INFORMATION REGARDING THE ANNUAL GENERAL MEETING

General

This proxy statement (“Proxy Statement”) has information about the 2026 Annual General Meeting of Shareholders (the “Annual Meeting”) and was prepared by our management for the Board of Directors (the “Board”) of Alpha and Omega Semiconductor Limited, an exempted limited liability company organized under the laws of Bermuda (“we,” “our,” “us,” or the “Company”). Our Board’s recommendation for each proposal is described in this Proxy Statement for which your vote is solicited.

In accordance with the “e-proxy” rules approved by the Securities and Exchange Commission (“SEC”) and in connection with the solicitation of proxies by the Board, on or about September 30, 2026, we will send a Notice of Internet Availability of Proxy Materials (the “Notice”) and provide access to our proxy materials (consisting of this Proxy Statement, our Annual Report on Form 10-K for the year ended June 30, 2026 and a form of proxy) over the internet to each shareholder entitled to vote at the Annual Meeting. We will not mail a full set of proxy materials to shareholders unless such shareholders request such mailing at http://www.investorvote.com/AOSL. We intend to mail to requesting shareholders full sets of our Proxy Materials (consisting of this Proxy Statement, our Annual Report on Form 10-K for the year ended June 30, 2026, and a form of proxy) within three to five business days from the date of receipt of such request.

Our Board asks you to appoint Mr. Stephen C. Chang, our Chief Executive Officer, and Yifan Liang, our Chief Financial Officer and Corporate Secretary, as your proxy holders to vote your shares at the Annual Meeting. You may make this appointment by properly completing the enclosed proxy as described below. If appointed by you, your shares represented by a properly completed proxy received by us will be voted at the Annual Meeting in the manner specified in the proxy card or, if no instructions are marked on the proxy card, your shares will be voted as described below. Although management does not know of any other matter to be acted upon at the Annual Meeting, unless contrary instructions are given, shares represented by valid proxies will be voted by the persons named on the accompanying proxy card in the manner the proxy holders deem appropriate for any other matters that may properly come before the Annual Meeting.

We maintain our registered office in Bermuda at Richmond House, 12 Par-la-Ville Road, Hamilton HM 08, Bermuda. Our telephone number in the United States is (408) 830-9742. The mailing address of our business offices in the United States is 475 Oakmead Parkway, Sunnyvale, CA 94085.

Record Date and Shares Outstanding

The record date for the Annual Meeting has been set as the close of business on September 17, 2026 (the “Record Date”). Only shareholders of record as of such date will be entitled to notice of and to vote at the meeting. On the Record Date, there were 30,305,071 issued and outstanding common shares, par value $0.002 per share (“common shares” or “shares”). Each issued common share is entitled to one vote on the proposals to be voted on at the Annual Meeting. Shares held as of the Record Date include common shares that are held directly in your name as the shareholder of record and those shares held for you as a beneficial owner through a broker, bank, trust or other nominee.

QUESTIONS AND ANSWERS RELATING TO THE ANNUAL GENERAL MEETING

Why did I receive these materials?

Only our shareholders as of the close of business on September 17, 2026, which we refer to as the “Record Date,” are entitled to vote at the Annual Meeting, which will be held at 8:00 a.m. on Wednesday, November 18, 2026, Taiwan local time (or 4:00 p.m. on Tuesday, November 17, 2026, U.S. Pacific Standard Time), at Illume Taipei Hotel, No. 100, Dun Hua N Rd., Songshan District, Taipei City, Taiwan. As a shareholder, you are invited to attend the Annual Meeting and are requested to vote on the items of business described in the Proxy Statement. We distribute the Proxy Statement and related materials to our shareholders of record on the Record Date.

The Proxy Statement provides notice of the Annual Meeting, describes the proposals presented for shareholder actions and includes information about the proposals, information concerning our management, corporate governance, principal shareholders and other relevant information. The accompanying proxy card also enables shareholders to vote on the matters without having to attend the Annual Meeting in person.

What is a proxy?

A proxy is your legal designation of another person to vote on your behalf. By completing and returning the enclosed proxy card, you are providing each of our Chief Executive Officer and Chief Financial Officer with the authority to vote your shares in the manner you indicate on your proxy card.

What are the proposals to be considered at the Annual Meeting and what vote is required to approve each proposal?

The Board is submitting the following five (5) proposals for shareholder actions at the Annual Meeting:

•Proposal 1 - the election of eight (8) nominees to serve as directors on our Board until the next annual general meeting of shareholders or until their successors are duly elected and qualified. The affirmative vote of a plurality of the votes cast at the Annual Meeting is required for the election of directors. “Plurality” means that the individuals who receive the highest number of votes are elected as directors, up to the number of directors to be chosen at the meeting. A properly executed proxy marked “withhold authority” with respect to the election of one or more directors will not be voted with respect to the director or directors indicated, although it will be counted for purposes of determining whether there is a quorum. Broker non-votes will have no effect on the outcome of the election of directors.

•Proposal 2 - the approval, on an advisory basis, of the compensation of our named executive officers as described in the Proxy Statement, commonly known as the “say-on-pay” vote. This proposal is deemed to be approved by shareholders if it receives the affirmative vote of holders of a majority of the votes cast in person or represented by proxy and entitled to vote at the Annual Meeting. However, Proposal 2 represents only an advisory vote of shareholders and is not binding on the Company, although our Board will consider results of the vote in setting the compensation of our named executive officers. Abstentions and broker non-votes will have no effect on the outcome of this proposal.

•Proposal 3 - the approval of the amendment and restatement of the Company’s 2018 Omnibus Incentive Plan to, among other things, increase the number of common shares authorized for issuance under such plan from 5,202,000 shares to 6,372,000 shares. The affirmative vote of holders of a majority of the votes cast in person or represented by proxy and entitled to vote at the Annual Meeting will be required to approve this proposal. Abstentions and broker non-votes will have no effect on the outcome of this proposal.

• Proposal 4 - the approval of the amendment and restatement of the Company’s 2018 Employee Share Purchase Plan to increase the number of common shares authorized for issuance under such plan from 3,700,000 shares to 5,700,000 shares. The affirmative vote of holders of a majority of the votes cast in person or represented by proxy and entitled to vote at the Annual Meeting will be required to approve this proposal. Abstentions and broker non-votes will have no effect on the outcome of this proposal.

•Proposal 5 - the approval and ratification of the appointment of Deloitte & Touche LLP (“Deloitte”) as our independent registered public accounting firm, and the authorization for our Board, acting through our Audit

Committee, to determine the remuneration of the accounting firm, for the fiscal year ending June 30, 2027. The affirmative vote of holders of a majority of the votes cast in person or represented by proxy and entitled to vote at the Annual Meeting will be required to approve this proposal. Abstention will have no effect on the outcome of this proposal.

How are votes counted and how will a broker non-vote be treated and counted?

If you are a “street name” holder or beneficial owner, you have the right to direct your broker, bank, trust or other nominee on how to vote your shares at the Annual Meeting. The broker, bank, trust or other nominee that is the shareholder of record for your shares is obligated to provide you with a voting instruction card for you to use for this purpose. If you hold your shares in a brokerage account but you fail to return your voting instruction card to your broker, your shares may constitute “broker non-votes.” Generally, broker non-votes occur on a matter when a broker is not permitted to vote on that matter without instructions from the beneficial owner and instructions are not given. If you are a beneficial owner and your broker, bank, trust or other nominee holds your shares in its name, it is not permitted for the broker, bank, trust or other nominees to vote your shares without your instructions on the election of directors (Proposal 1); the “say-on-pay” vote (Proposal 2); the approval of the amendment and restatement of the 2018 Omnibus Incentive Plan (Proposal 3); and the approval of the

amendment and restatement of the 2018 Employee Share Purchase Plan (Proposal 4). The broker, bank, trust or other nominees, however, are permitted to vote for the approval and ratification of the appointment of Deloitte & Touche LLP (Proposal 5), therefore we do not expect any broker non-votes for Proposal 5. Broker non-votes are counted for purposes of establishing a quorum. A properly executed proxy marked “abstain” with respect to Proposals 2, 3, 4 will not be voted, although

they will be counted for purposes of determining whether there is a quorum. The effects of broker non-votes for each proposal are described in more detail in response to the previous question above.

For Proposal 1 with respect to the election of directors, you may vote “FOR” all or some of the nominees or you may vote “WITHHELD” with respect to one or more of the nominees. You may not cumulate your votes for the election of directors. Broker non-votes do not have any effect on the outcome of the votes.

For Proposal 2 with respect to the “say-on-pay” vote, you may vote “FOR,” “AGAINST” or “ABSTAIN.” Abstentions and broker non-votes will have no effect on the outcome of the votes.

For Proposal 3 with respect to the amendment and restatement of the 2018 Omnibus Incentive Plan, you may vote “FOR,” “AGAINST” or “ABSTAIN.” Abstentions and broker non-votes will have no effect on the outcome of the votes.

For Proposal 4 with respect to the amendment and restatement of the 2018 Employee Share Purchase Plan, you may vote “FOR,” “AGAINST” or “ABSTAIN.” Abstentions and broker non-votes will have no effect on the outcome of the votes.

For Proposal 5 with respect to the appointment and election of Deloitte & Touche LLP as the Company’s independent registered public accounting firm, you may vote “FOR,” “AGAINST” or “ABSTAIN.” Abstentions will have no effect on the outcome of the votes.

Who is entitled to vote at the Annual Meeting?

Only shareholders of record at the close of business on the Record Date are entitled to receive notice of and to participate and vote in the Annual Meeting and any adjournment or postponement thereof. If you were a shareholder of record on the Record Date, you will be entitled to vote all of the shares that you held on that date at the Annual Meeting.

How many votes do I have?

You will be entitled to one vote for each outstanding share of our common shares you own as of the Record Date. As of the Record Date, there were 30,305,071 shares of our common shares outstanding and eligible to vote at the Annual Meeting.

What is the difference between a “shareholder of record” and a “street name” holder or a “beneficial owner”?

As the shareholder of record, you have the right to grant your voting proxy directly to our management or to vote in person at the Annual Meeting. If your shares are held in a brokerage, bank, trust or other nominee, you are considered the beneficial owner of shares held in “street name.” As the beneficial owner, you have the right to direct your broker, bank, trust or nominee how to vote and are also invited to attend the Annual Meeting.

How can I vote my shares at the Annual Meeting?

If you are a shareholder of record, you may vote by mailing a completed proxy card, via the Internet, or by telephone. To vote by mailing a proxy card, sign and return the enclosed proxy card in the enclosed prepaid and addressed envelope and your shares will be voted at the Annual Meeting in the manner you directed. Instructions for voting via the Internet are described in the proxy card attached to the Proxy Statement. To vote by telephone, call toll free 1-800-652-VOTE (8683) within the USA, US territories and Canada. You may also vote in person at the Annual Meeting.

If you are a beneficial owner, your broker, bank, trust or nominee should have provided voting instructions for you to use in directing them how to vote your shares. You may be eligible to vote your shares over the Internet rather than by mailing a completed voting instruction card provided by the broker, bank, trust or nominee. Please check the voting instructions card provided by your bank or brokerage house for instructions. You may also vote in person at the Annual Meeting. To do so, you must obtain a legal proxy from the broker, bank, trust or other nominee that holds your shares giving you the right to vote the shares. Please contact that organization for instructions regarding obtaining a legal proxy.

Can I vote electronically through the Internet?

If you are a shareholder of record, you may vote electronically through the Internet at www.investorvote.com/AOSL. The instructions are included in your proxy card.

If your shares are held in “street name,” please check your proxy card or contact your broker, bank, trust or other nominee to determine whether you will be able to vote electronically through the Internet and the deadline for such voting.

Can I change my vote after I return my proxy card?

Yes. If you are a shareholder of record and submitted your proxy through the mail or Internet, you may revoke your proxy before the vote is taken at the Annual Meeting by any of the following ways:

•granting a proxy through the Internet after the date of your original proxy and before the deadlines for voting included on your proxy card;

•submitting a later-dated proxy by mail before your earlier-dated proxy is voted at the Annual Meeting;

•giving written notice of the revocation of your proxy to our Corporate Secretary at the address shown above that is actually received by our Corporate Secretary prior to the Annual Meeting; or

•voting in person at the Annual Meeting.

If you are a “street name” holder, you may change your vote by submitting new voting instructions to your broker, bank, trust or other nominee or, if you have obtained a legal proxy from your broker, bank, trust or other nominee giving you the right to vote your shares, by attending the Annual Meeting and voting in person. In either case, the powers of the proxy holders will be suspended if you attend the Annual Meeting in person and so request, although attendance at the Annual Meeting will not by itself revoke a previously granted proxy.

How many shares must be present or represented to conduct business at the Annual Meeting?

The presence at the Annual Meeting of at least two shareholders, in person or by proxy and entitled to vote, representing not less than 50% of the aggregate voting power of the Company’s common shares issued and outstanding on the Record Date, will constitute a quorum, permitting the conduct of business at the Annual Meeting.

Proxies received but marked as abstentions, votes withheld and broker non-votes (as described below) will be included in the calculation of the number of shares present at the Annual Meeting for quorum purposes.

What happens if the Annual Meeting is postponed or adjourned?

Your proxy may be voted at the postponed or adjourned meeting. You will still be able to change your proxy until it is voted.

Who can attend the Annual Meeting?

All shareholders of record as of the close of business on the Record Date may attend the meeting. To attend the Annual Meeting, please follow these instructions:

•If you are a shareholder of record, bring proof of ownership of your shares and a form of identification; or

•If you are a “street name” holder, bring proof of ownership of your shares through your broker, bank, trust or nominee, and a form of identification. You must have obtained a “legal proxy” from your broker, bank, trust or nominee to vote at the Annual Meeting.

What are the Board’s recommendations?

Unless you give other instructions on your proxy card, the person named as proxy holder on the proxy card will vote in accordance with the recommendations of the Board. After careful consideration, the Board recommends the following vote for proposals:


	Proposals	Recommendation of the Board

1	Election of Directors	For all Nominees

2	Approval on an advisory basis of the compensation of our named executive officers	For

5	Approval and ratification of the appointment of Deloitte & Touche LLP as our independent registered public accounting firm and authorization for the Board, acting through our Audit Committee, to determine its remuneration for the fiscal year ending June 30, 2027	For

Will shareholders be asked to vote on any other matters?

To the knowledge of the Company and its management, shareholders will vote only on the matters described in the Proxy Statement. However, if any other matters properly come before the Annual Meeting, the persons named as proxies for shareholders will vote on those matters in the manner they consider appropriate.

What should I do if I receive more than one set of voting materials?

You may receive more than one set of voting materials, including multiple copies of the Proxy Statement and multiple proxy cards or voting instruction cards. For example, if you hold your shares in more than one brokerage account, you may receive a separate voting instruction card for each brokerage account in which you hold shares. If you are a shareholder of record and your shares are registered in more than one name, you will receive more than one proxy card. Please complete, sign, date and return each proxy card and voting instruction card that you receive.

How can I find out the results of the voting at the 2026 Annual Meeting?

Preliminary voting results will be announced at the Annual Meeting. Final voting results will be disclosed in a Current Report on Form 8-K filed with the SEC at the website, www.sec.gov, within four business days after the Annual Meeting or any adjournment or postponement thereof.

Who bears the costs of proxy solicitation?

The Company will bear the entire cost of this solicitation of proxies, including the preparation, assembly, printing, and mailing of this Proxy Statement, the proxy card, and any additional solicitation materials that the Company may provide to

shareholders. The Company may also decide to engage a proxy solicitation firm to assist in the solicitation of votes, although the Company has not engaged such firm prior to the filing of this proxy statement. If the Company engages a proxy solicitation firm, the Company will pay its fees and expenses. Copies of solicitation materials will be provided to brokerage firms, fiduciaries and custodians holding shares in their names that are beneficially owned by others so that they may forward the solicitation materials to such beneficial owners. The Company will reimburse the brokerage firms, fiduciaries and custodians holding shares in their names for reasonable expenses incurred by them in sending solicitation materials to its beneficial shareholders. The solicitation of proxies will be made by various methods, including by mail, electronic mail, telephone, facsimile, or personally by directors, officers and employees of the Company who will receive no extra compensation for such services.

Mr. Michael Pfeiffer will not stand for re-election at the Annual Meeting, and his service as a member of our Board will end immediately after the Annual Meeting. Our Board is the decision-making body responsible for, among other things, determining policies and guidelines for our business. Our Board also supervises our executive officers and monitors their implementation of policies and guidelines established from time to time by our Board.

No shareholder has the contractual right to designate persons to be elected to our Board, and our Bye-laws provide that directors be elected upon a resolution passed at a duly convened shareholders meeting, to hold office for such term as the shareholders may determine or until their successors are appointed or elected in accordance with our Bye-laws. There is no age limit requirement for qualification to serve as a member of our Board. While share ownership is not a required qualification for a director nominee, our Board has adopted stock ownership guidelines for executive officers and non-employee directors who are elected to serve on the Board.

We have determined that each of our directors and director nominees, except for Mr. Stephen Chang, our Chief Executive Officer and Dr. Mike F. Chang, our Executive Vice President of Strategic Initiatives, is an “independent director” under the current corporate governance rules of the NASDAQ Global Select Market and applicable rules and regulations under the Securities Exchange Act of 1934, as amended (the “Exchange Act”).

Board Meetings and Committees; Annual Meeting Attendance

Our Board held four meetings during the fiscal year ended June 30, 2026, including regular scheduled meetings and special meetings called in connection with reviewing time-sensitive matters. During the fiscal year ended June 30, 2026, each director attended or participated in eighty-nine percent (89%) or more of the aggregate of (i) the total number of meetings of the Board during the period for which he or she has been a director and (ii) the total number of meetings held by all committees of the Board on which the director served during fiscal year 2026. All of our Board members attended our 2025 annual general meeting of shareholders.

Committees of the Board

We have three standing committees: an Audit Committee, a Compensation Committee, and a Nominating and Corporate Governance Committee. We believe that the composition of these committees meets the criteria for independence, and the functioning of these committees complies with, the applicable requirements, of the Sarbanes-Oxley Act of 2002, as amended, the current rules of the NASDAQ Global Select Market and applicable SEC rules and regulations. The written charters for our Audit Committee, Compensation Committee, and Nominating and Corporate Governance Committee are available at the Investor Relations section of our website at http://investor.aosmd.com/. The contents of this website are not a part of the Proxy Statement. In addition, the Board may delegate certain authorities and powers to a committee of the Board established from time to time in accordance with the Bye-laws of the Company and applicable laws.

Each committee has the composition and responsibilities described below:

Audit Committee

Our Audit Committee currently consists of Claudia Chen, Michael L. Pfeiffer and Michael J. Salameh, and following the Annual Meeting is expected to consist of Claudia Chen, Michael J. Salameh, and So-Yeon Jeong. The Audit Committee is chaired by Ms. Claudia Chen. Our Board of Directors has determined that Ms. Claudia Chen is an Audit Committee financial expert, as defined by the rules and regulations promulgated by the SEC.

Leadership Structure of the Board

Currently Dr. Mike F. Chang is our Executive Vice President of Strategic Initiatives and serves as Chairman of the Board, and Mr. Stephen Chang serves as our Chief Executive Officer and a director. The Board believes this is the optimal and most effective leadership structure but continues to monitor and review such structure from time to time. The Board also believes this leadership structure will ensure that the Company achieves the next level of success as it pursues its ambitious business and financial objectives.

Dr. Chang has extensive knowledge of the power semiconductor industry and an in-depth understanding of our strategic initiatives, which make him well suited to set the agenda and lead the discussions at board meetings. He also facilitates communications between the Board and management by ensuring a regular flow of information, thereby enhancing the Board's ability to make informed decisions on critical issues facing our company. In addition, the Board has appointed a lead independent director, Mr. Michael J. Salameh. The lead independent director presides over all executive sessions of independent directors and coordinates activities and communications between the management and independent directors. He also has the responsibility to serve as a liaison between independent directors and the Chairman, communicate with major shareholders as appropriate, and review and approve scheduling of Board meetings and executive sessions.

To ensure a strong independent Board of Directors, six (6) out of the total eight (8) members of our Board following the Annual Meeting will be independent directors. The Board holds executive sessions where only independent directors attend, and these executive sessions provide an effective method to perform oversight and advisory functions of the Board. In addition, our Audit, Compensation and Nominating and Corporate Governance Committees consist solely of independent directors. We believe that the Board leadership described above is the best structure to lead us in the achievement of our goals and objectives and establishes an effective balance between management leadership and appropriate oversight by independent directors.

Oversight of Risk Management by the Board

One of the key functions of our Board is informed oversight of our risk management process. The Board administers this oversight function directly through the Board as a whole, through standing committees and ad-hoc committees of the Board that address risks inherent in their respective areas of oversight, as well as through our lead independent director. In particular, our Board is responsible for monitoring and assessing strategic and operational risk exposure, including risks associated with acquisition of significant assets, changes in business models, major corporate transactions and market conditions in the semiconductor industry. Our Audit Committee has the responsibility to consider and discuss our major financial risk exposures and the steps our management has taken to monitor and control these exposures, including guidelines and policies to govern the process by which risk assessment and management is undertaken. The Audit Committee provides general oversight of our financial reporting, internal controls and audit functions. The Audit Committee also established the Cybersecurity Subcommittee, which provides oversight and management on cybersecurity risks and supervise the Company’s responses to cybersecurity incidents. The Cybersecurity Subcommittee reports to the Board on major cybersecurity issues and has various responsibilities in all IT related matters, including review of the quality and effectiveness of our policies and procedures with respect to our IT systems, as well as compliance with applicable regulatory requirement relating to cybersecurity matters. Our Compensation Committee assesses and monitors whether any of our compensation policies and programs has the potential to encourage excessive risk-taking. Our Nominating and Corporate Governance Committee monitors the effectiveness of our corporate governance guidelines and is primarily responsible for assessing the risks associated with corporate governance

practices, the independence of our directors, and management succession plans. In addition, the Shareholders Communications Subcommittee of the Nominating and Corporate Governance Committee has the responsibility to manage any risks relating to investors relationships and ESG matters. In addition, the Board establishes ad-hoc special committees to provide independent oversight and review of significant transactions or matters affecting the Company.

Nominations for Election of Directors

Director Qualifications

The Nominating and Corporate Governance Committee utilizes a variety of criteria to evaluate the qualifications and skills necessary to serve as members of our Board. The Nominating and Corporate Governance Committee may assess character, judgment, diversity, business acumen, scientific expertise, familiarity with issues affecting the semiconductor industry and other backgrounds and attributes that are needed to help strengthen and balance the Board. Other qualifications will be determined on a case-by-case basis, depending on whether the Nominating and Corporate Governance Committee desires to fill a vacant seat or increase the size of the Board to add new directors. In addition, while the Nominating and Corporate Governance Committee does not prescribe specific diversity standards, the Committee considers diversity in the context of the Board as a whole and takes into account the personal characteristics and experiences of current and prospective directors, as well as other traits and attributes, that reflect a broad range of perspectives and diverse backgrounds in the Board’s decision making process.

Identification and Evaluation of Nominees for Directors

The Nominating and Corporate Governance Committee utilizes a variety of methods for identifying and evaluating nominees for director. The Nominating and Corporate Governance Committee assesses the appropriate size of the Board, and whether any vacancies on the Board are expected due to retirement or otherwise. In the event that vacancies are anticipated, or otherwise arise, the Nominating and Corporate Governance Committee considers various potential candidates for director. In addition, the Board and the Nominating and Corporate Governance Committee may form ad-hoc sub-committees to consider potential nominees and their qualification. Candidates may come to the attention of the Nominating and Corporate Governance Committee through current members of the Board, executive officers, professional search firms, shareholders or other persons. These candidates are evaluated at regular or special meetings of the Nominating and Corporate Governance Committee, and may be considered at any point during the year. The Nominating and Corporate Governance Committee recommends the director nominees to our Board for approval for election at each annual general meeting of shareholders. Under our Bye-laws, any director appointed by our Board is subject to re-election by shareholders at our next annual general meeting of shareholders. The nominees for election at this annual general meeting were recommended and approved unanimously by members of our Nominating and Corporate Governance Committee and the Board, respectively.

A shareholder seeking to recommend a prospective nominee for the Nominating and Corporate Governance Committee’s consideration should submit the candidate’s name and qualifications to our Corporate Secretary at our business office in the United States at 475 Oakmead Parkway, Sunnyvale, California 94085. The Nominating and Corporate Governance Committee will consider a properly submitted shareholder nomination that meets the requirements under our Bye-laws and applicable U.S. federal securities laws. Our Bye-laws require, among other things, an advance written notice of the nomination in writing of not less than sixty (60) nor more than one hundred and eighty (180) days from the date of the annual general meeting. This notice must also include certain information relating to the nominee and the nominating shareholders, as described in more detail below in “Future Shareholder Proposals and Nominations for the 2027 Annual General Meeting.”

Shareholder Communication with our Board

Although we do not have a formal policy regarding communications with the Board, shareholders may communicate with the Board, including the independent directors, by sending a letter to Alpha and Omega Semiconductor Limited, Board of Directors, c/o Investor Relations, Alpha and Omega Semiconductor, Inc., 475 Oakmead Parkway, Sunnyvale, CA 94085. Shareholders may also direct their submission to a particular member of the Board.

Code of Ethics

Our Board has adopted the Code of Business Conduct and Ethics (the “Code”) that applies to members of senior management, including the Chief Executive Officer, as well as all other employees of the Company. Our Code of Business Conduct and Ethics is publicly available on our website at https://investor.aosmd.com/corporate-governance/governance-documents/default.aspx. In the event that we make any amendments to or grant any waivers of, a provision of the Code that applies to the principal executive officer, principal financial officer, or principal accounting officer that requires disclosure under applicable SEC rules, we intend to disclose such amendment or waiver, and the reasons therefor, on our website at

www.aosmd.com, in the Investors section.

Corporate Responsibilities

Environment Sustainability

We recognize that environmental responsibility plays an important part in the manufacturing of our products. The semiconductor production process, including the semiconductor wafer manufacturing and packaging process, generates air emissions, liquid wastes, wastewater and other industrial and hazardous materials. We understand the impact our operations have on the environment, the community, as well as the health and safety of our employees, contractors, and suppliers. Therefore, we are fully committed to environmentally sustainable business practices and to minimizing the environmental impact across our supply chain. We expect our suppliers and vendors to adhere to the same environmentally sustainable business practices.

For example, we have installed various types of pollution control equipment for the treatment of air emissions and liquid waste and equipment for recycling and treatment of water in our packaging and testing facilities in China and wafer manufacturing facility in Oregon, USA. Waste generated at our manufacturing facilities, including acid waste, alkaline waste, flammable waste, toxic waste, is collected and sorted for proper disposal. Our operations in China are subject to regulation and periodic monitoring by China’s State Environmental Protection Bureau, as well as local environmental protection authorities, including those under the Shanghai Municipal Government, which may in some cases establish stricter standards than those imposed by the State Environmental Protection Bureau. Our operation in Oregon is subject to Oregon Department of Environmental Quality regulations, Federal Environmental Protection Agency laws and regulations, and local jurisdictional regulations. We have been in material compliance with all applicable environmental regulations and standards and have not had a material or adverse effect on our results of operations from complying with these regulations.

We have implemented the International Organization for Standardization (“ISO”) 14001 environmental management system in our manufacturing facilities in China and Oregon. We also require our subcontractors, including foundries and assembly houses, to meet ISO 14001 standards. We have adopted pollution control measures for the effective maintenance of environmental protection standards consistent with the requirements applicable to the semiconductor industry in China and the U.S. Our key suppliers are either ISO14001 or EMAS certified.

Climate change is identified as one of the greatest challenges facing nations, governments, businesses and citizens over future decades. Climate change has implications for both human and natural systems and could lead to significant changes in resource use, production and economic activity. In response, we have been recognized in accordance with ISO 14064-1 worldwide standard, which means that we develop and implement programs to limit greenhouse gas (GHG) concentrations. Such GHS initiatives rely on the quantification, monitoring, reporting and verification of GHG emissions or removals.

Our products comply with the European Directive 2011/65/EU regarding the restriction of the use of certain hazardous substances in electrical and electronic equipment (“RoHS”), which requires that the products do not contain more than agreed levels of toxic substance. Our manufacturing facilities in China also obtained QC080000 certification, which is an IECQ Certificate of Conformity Hazardous Substance Process Management, and obtained a Certificate of Green Partner for Sony Green Partner Program. We avoid using these restricted materials to the extent possible when we design our products.

As part of our broader business strategies, we continue to develop innovative, proprietary and cutting-edge technology to design and manufacture power semiconductor products that meet the high standards of our customers. These standards include the achievement of specified power and electric efficiency of various consumer products. We believe our advanced technology enables us to deliver products that saves energy and improves power efficiency of consumer electronics, which has a positive impact on our environment.

Key ongoing initiatives include:

•PFAS Chemicals elimination – We have made meaningful progress in phasing out per- and polyfluoroalkyl substances (PFAS) from our manufacturing processes. We continue to pursue further reductions across our operations in alignment with evolving regulatory requirements and our own sustainability goals and aim to be PFAS free on all products by 2030.

•Renewable Energy Sourcing – We took steps in FY26 to expand the use of renewable energy and plan to continue these efforts as part of our broader strategy to reduce greenhouse gas emissions associated with our operations.

•F-GHGs Abatement – We have installed advanced abatement systems on all fluorinated greenhouse gas (F-GHG) manufacturing processes to minimize emissions of high-global-warming-potential gases.

•Supplier Code of Conduct – To reinforce our expectations for responsible environmental and business practices across our supply chain and operations, we have published our Supplier Code of Conduct on our company website. In 2026,

our manufacturing facilities in China and Oregon also completed Responsible Business Alliance (RBA) audits, further supporting our commitment to responsible and sustainable business practices.

•Waste Reduction and Recycling – We are committed to reducing waste and increasing reuse and recycling across our operations. At our Oregon manufacturing facility, approximately 88% of waste generated is currently diverted from landfill through reuse or recycling, supporting our goal of achieving zero waste to landfill by 2030.

Conflict Minerals

We are dedicated to ensuring that we use responsibly sourced minerals in both our supply chain as well as through our suppliers. The armed conflict and human rights atrocities that proliferate and are funded by the exploitation of natural resources in the Democratic Republic of Congo and adjoining countries (“DRC”) are unacceptable and any manufacture of product connected with this will not be tolerated.

Commonly known conflict minerals are those such as tantalum, tin, tungsten, and gold. Conflict minerals originating from the DRC must not be included in materials or products supplied to the Company. We are committed to ensuring an ethical and diverse supply chain that is focused on responsible mineral sourcing. We require all of our suppliers who manufacture raw metal materials containing tantalum, tin, tungsten or gold to implement their own conflict mineral policies. All such suppliers are required to undertake reasonable due diligence within their supply chains to ensure that the minerals are not being sourced from mines in conflict areas. We support the traceability and transparency of such information so that our customers can be assured that the metals used in their products are not contributing to any conflicts and come from sustainable sources.

Social Responsibility

At AOS, we are dedicated to fostering a culture of diversity, respect, and inclusion. We believe that every individual brings unique perspectives and talents that enrich our community and drive our collective success.

Commitment to Diversity: We actively seek to build a diverse team that reflects varied backgrounds, experiences, and perspectives of our global community. By embracing diversity, we enhance our creativity, innovation, and decision-making processes.

Commitment to Respect: Respect is at the core of our values. We are dedicated to treating every individual with dignity and fairness, recognizing the inherent worth of each person. We promote open dialogue and actively listen to different viewpoints, fostering an environment where everyone feels heard and appreciated.

Commitment to Inclusion: Inclusion is about ensuring that all voices are heard and valued. We strive to create a workplace where everyone feels a sense of belonging and can contribute to their fullest potential. Our policies, practices, and programs are designed to support an inclusive culture where everyone can thrive.

Human Rights and Labor Practices

We are committed to protect, improve and promote the welfare of our employees, partners and communities. We strive to provide an environment in which our employees can fully unleash their talents, and are treated with respect, care and dignity. We make great efforts to coach, train, and develop all employees so that they can grow their career at the Company while contributing to business growth. We train our managers to become good stewards for our employees, balancing the need for humanity while driving performance results. Our employees appreciate and value the strength of our people-oriented environment and the benefits our workplace diversity brings.

We offer competitive and fair compensation and benefits packages which include but are not limited to a combination of base salary, annual bonus, discretionary bonus for outstanding achievements, Employee Share Purchase Plan, and time-based and performance based long term equity compensation. The equity-related compensation programs are designed to motivate and incentivize our employees and link their rewards to financial and other strategic business performance results and at the same time increase our shareholder value.

We regularly host employee engagement activities such as social and team-building events, summer picnics, and holiday parties so that employees have an opportunity to connect and collaborate with their colleagues in an effort to strengthen our team-oriented culture. AOS believes strongly in our open-door policy which is in place to assist and encourage employees to discuss with management any concerns, issues and ideas relating to their working conditions and careers. In particular, at our China manufacturing location, we conduct bi-annual employee satisfaction surveys to solicit employee feedback, upon which we perform deep dives to understand the underlying needs so that we can identify and implement improvement measures accordingly. We upgrade our worker dormitory and on-site canteen facilities as well as office areas to improve worker’s

satisfaction. In addition, we actively identify development needs of focus groups and organize various training programs to elevate organizational capabilities. We organize quarterly worker communication meetings to address workers’ needs and foster continuous improvement. Our most recent surveys not only indicated a record high participation rate, but also revealed that employees across the board were more satisfied in their jobs now than they were in previous years. At our various locations, we engage with employees requiring ADA accommodations to ensure that workplace environments are appropriately designed to support their needs. All of these efforts contribute to enhanced employee engagement and morale.

We are committed to complying with labor standards and fair business practices everywhere we do business, and our Board has adopted a Labor and Human Rights Policy that applies to employees, interns, suppliers, agents, representatives, consultant and advisors. With respect to AOS’s specific business and countries of operation, we have assessed the below topics as the greatest potential impact for our company on human rights:

•Prohibition on Forced or Compulsory Employment or Labor: AOS ensures all work is voluntary and free from any form of forced labor. We prohibit bonded labor, involuntary prison labor, slavery, and trafficking. Workers have unrestricted movement within company facilities, and AOS ensures clarity in employment terms and forbids any fees charged to employees.

◦To ensure proper implementation, we conduct regular training with managers to ensure they understand their obligations related to Prohibition on Forced or Compulsory Employment or Labor. Employees are informed of this mandate through transparent quarterly meetings. Further, our hiring process includes checks conducted to affirm these mandates are upheld.

•Prohibition of Child Labor: Child labor is strictly prohibited under company policy. AOS adheres to local minimum age laws and immediately discontinues engagement with suppliers or subcontractors found utilizing child labor.

◦In practice, this involves regular training of those involved in the hiring process to ensure compliance. Additionally, we maintain strict oversight, with designated responsibilities across HR, EHS, and payroll teams to ensure that all processes meet health, safety, and labor standards, including immediate reporting and rectification of any child labor incidents.

•Fair and Transparent Employment Practices: We commit to fair labor practices, providing wages and benefits that meet or exceed the minimum standards in the countries we operate in. Compliance with local labor and wage laws is strictly followed, covering minimum wage, overtime, and legally mandated benefits.

◦To ensure proper follow through, our human resources and payroll teams oversee adherence local labor and wage laws. At some work locations we have implemented dedicated working hours control teams which are charged with monitoring compliance to overtime rules, analyzing issues, and suggesting improvements to maintain effective labor practices.

•Human Rights and Non-Discrimination in the Workplace: The Company maintains a workplace free from discrimination and harassment, supporting equality and respecting minority rights.

◦At AOS, we provide comprehensive training to managers and employees on the prevention of discrimination and harassment in the workplace. We actively and timely address related worker complaints and encourage employees to raise issues of concern through various channels such as directly to a management or human resources representative, utilization of Lighthouse Services a third-party service provider, WeChat or email. We take great measure to ensure prompt follow-up and resolutions by all relevant departments.

•Freedom of Association and Collective Bargaining: AOS respects the rights of workers to organize, form trade unions, engage in collective bargaining, and participate in peaceful assembly, all in accordance with local laws, while also respecting the rights of workers to refrain from such activities.

◦In practice, HR and the union actively inform employees about their rights to unionize or opt-out, and jointly facilitate policy discussions relevant to employee interests. Additionally, the company maintains robust communication through regular meetings and bi-annual and annual surveys to continually assess and enhance employee engagement, workplace safety and job satisfaction. These survey results have led to improvements in workplace dormitory and canteen facilities as well as led to the development of focus groups to enhance worker training programs.

As a global company, we seek to conduct business operations in accordance with international human rights principles including the UN Guiding Principles on Business and Human Rights. We recognize the value of a diverse and inclusive workforce and work diligently to uphold and maintain work environments that promote equal opportunities and are free of discrimination and harassment on the basis of protected classifications. As such, employees failing to meet these expectations will be held to our internal accountability standards and procedures.

Health and Safety

AOS has established a health and safety management system to eliminate or minimize the risks to personnel and other parties who could be exposed to hazards associated with its activities. Such system includes:

• Occupational Safety: We protect our workers from hazards such as chemicals, electricity, and fire by enforcing engineering controls, preventive maintenance, safe work practices, and comprehensive safety training. Employees are equipped with necessary protective gear and educated on its proper use.

• Emergency Preparedness: AOS is proactive in identifying potential emergencies, developing reporting mechanisms, and training employees through drills. We maintain equipped emergency exits and recovery plans to handle crises effectively.

• Occupational Injury and Illness: We implement rigorous procedures to prevent, manage, and report occupational injuries and illnesses. This includes promoting thorough incident reporting and providing essential medical equipment.

• Facilities Management: AOS provides facilities that adhere to health standards, offering clean sanitation facilities, potable water, and safe food handling areas. We manage environmental health risks by regularly assessing and controlling exposures to hazards.

• Employee Accommodation and Communication: We accommodate employees with disabilities and ensure all health and safety communications are clear and accessible, promoting an open dialogue about safety concerns.

Our commitment is to comply with applicable legal requirements. Under the control of the health and safety management system, we are able to control hazards originating within the workplace which could adversely affect the health and safety of our employees. We ensure that we regularly deliver health and safety training to our employees to eliminate or minimize the risks.

The health and safety of our employees are of paramount importance to the Company. At each of our major locations, we have established a site safety committee to conduct routine meetings to check and review the effectiveness of our policies and guidelines, incident rates, and oversee the implementation of corrective actions to ensure a safe and healthy work environment. We have implemented ISO45001 Occupational health and safety management systems in our manufacturing facility in China. We monitor and follow requirements and guidance related to disease prevention in the workplace published by the US Occupational Safety and Health Administration.

In August 2026, our China manufacturing facility activated its emergency response protocols in response to severe typhoon and flooding conditions. With employee safety as the highest priority, the site implemented established preparedness and response measures, including early-warning procedures, facility protection, safety communications, appropriate personal protective equipment, and evacuation protocols. Our EHS team maintained continuous on-site emergency coverage, monitored employee wellbeing, coordinated with local authorities, and prioritized personnel safety throughout the event.

Community Engagement and Workforce Development

We take proactive actions to support our communities in which we conduct our business operations. Our commitment is particularly focused on developing the next generation of skilled workers and creating pathways to rewarding careers in advanced manufacturing and semiconductor technology.

We maintain a state-of-the-art and advanced semiconductor manufacturing facility, named Jireh Semiconductor, in Hillsboro, Oregon, where we employed approximately 620 local residents as of August 25, 2026. Since 2012, we have invested more than $300 million to upgrade, improve and enhance this facility, which allowed us to provide high-paying jobs and long-term careers to Oregon residents, while contributing to the strength and economic vitality of the local community.

A key part of our workforce strategy is building awareness of advanced manufacturing careers and creating opportunities for students and educators to better understand the skills and career pathways available within the semiconductor industry. We help lead the Advanced Manufacturing Training and Education Coalition of Hillsboro (AM-TECH), which supports awareness

and training for the manufacturing industry. We also collaborate with the School District to support Educator Externship programs, where teachers and counselors learn about career opportunities in semiconductor manufacturing and share that knowledge with students.

We also helped develop and sponsor the first Oregon-Manufacturing Youth Apprenticeship program, with the students completing a two-year apprenticeship program. Our third cohort of four students will begin at the start of the 2026/2027 school year. The two-year program provides students with meaningful, hands-on experience and an opportunity to develop skills that can lead to careers in advanced manufacturing. We have graduated seven students to date and three have stayed with us and started their careers.

We participate in Manufacturing Day and other events that bring local high school students to tour our facility and learn about the process and science behind semiconductor technology. These experiences provide students with a firsthand understanding of advanced manufacturing and demonstrate that rewarding technical careers are available close to home.

We also continue to support the Career and College Pathways programs at our local School District, support the Hillsboro Schools Foundation and partner with Portland Community College to help develop educational and training programs aligned with the needs of today's manufacturing workforce. These partnerships help create clearer connections between education, technical training, and employment opportunities.

In addition, as a member of the State of Oregon’s Higher Education Coordinating Commission Manufacturing Industry Consortium, we are actively involved in identifying and supporting initiatives and strategies that enable the manufacturing industry to engage workforce, develop talents and align economic opportunity with local communities.

By investing in local people, education, training, and career pathways, we are helping build a stronger and more sustainable workforce for Oregon while supporting the continued growth of U.S. semiconductor manufacturing, design and research, thereby fortifying our nation’s chip supply chains. In doing so, we contribute to the resilience of our nation's semiconductor supply chains and help ensure that the communities where we operate can participate in the opportunities created by this critical industry.

Governance

Our Code provides guidelines for our employees and members of the Board to exercise good judgment to ensure the safety and welfare of all personnel and to maintain a cooperative, efficient, positive, harmonious and productive work environment and business organization. The Code covers policies related to governance, ethics, and corporate social responsibility. It describes how we conduct business with integrity towards employees, customers, stockholders, suppliers, and all other third parties. It sets forth what the Company values, what we prohibit as a company, and highlights programs and resources to help employees meet these expectations. The Code can be found on our website (www.aosmd.com) in the Investors section.

In summary, the Code addresses the following topics:

•Conflicts of Interest;

•Corporate Opportunities;

•Protecting the Company’s Confidential Information;

•Obligations under Securities Laws – Insider Trading

•Financial Matters and Disclosure Obligations;

•Use of Company’s Assets;

•Anti-Bribery and Corruption

•Anti-Discrimination or Harassment.

The Company is committed to fostering ongoing dialogue with all its stakeholders through multiple channels and offers employees, business partners and other stakeholders an opportunity to report any suspected ethical issues or violations of the Code or law, and to do so anonymously (where permissible by law) or with attribution. The Company makes every effort to investigate reported concerns appropriately, consistently, and in a timely manner, including promptly responding to any concerns or reports of employee misconduct and inquiries from any government agency. Furthermore, during the fiscal year, the Company has committed additional resources to improve and enhance its legal and regulatory compliance capabilities, including the hiring of additional staff attorneys; implementing new corporate and compliance policies and procedures; and providing more training and educational opportunities to employees on compliance matters.

Our Board has adopted the Corporate Governance Policy to establish a framework within which it will conduct its business. We also provide our directors training on issues facing us and on subjects that would assist the directors in discharging their duties. In addition, the Board has adopted a share ownership guideline for our executive officers and non-employee members of the Board, which align the interests of our management members with those of our shareholders. The

Corporate Governance Policy can be found on our website (www.aosmd.com) in the Investors section; none of the material on our website is part of this Proxy Statement or is incorporated by reference herein. In addition, we have established the Shareholders Communications Subcommittee that is responsible for managing and providing oversight on ESG matters.

The Company and our Board are committed to a diverse, inclusive and equitable environment where all Board members, staff, and volunteers feel respected and valued regardless of gender, age, race, ethnicity, national origin, sexual orientation or identity, disability, or any other bias. The Board believes in the benefits of having a Board composed of individuals with diverse skills, experience, backgrounds and perspectives as well as support for the mission of the Company. For purposes of Board composition, diversity includes, but is not limited to, business and industry skills and experience, gender and ethnicity. All Board appointments should collectively reflect the diverse nature of the business environment in which the Company operates and be made on merit, in the context of the skills, experience, qualification and knowledge which the Board requires to be effective. The Board is committed to complying with all federal, state and local laws and regulations regarding diversity of composition of the Board, including any diversity legislation enacted by state governments to the extent the Company is subject to such legislation.

Our Shareholders Communications Subcommittee reviews, assesses, and recommends actions relating to our ESG capabilities and consults with our counsel and advisors regarding compliance with applicable laws, regulations and rules relating to ESG matters. The Shareholders Communications Subcommittee reports directly to the Board regarding ESG matters at least twice a year.

COMPENSATION OF NON-EMPLOYEE DIRECTORS

Our non-employee director compensation policy provides for the following cash and equity compensation:

Cash Retainer and Fees: Each non-employee director serving as a member of the Board at the beginning of the Company’s fiscal year will receive an annual retainer of $60,000 and the Lead Independent director will receive an additional retainer of $21,000. In addition, each non-employee director serving as the chairperson of a committee of the Board will receive an additional retainer as follows: Audit Committee - $25,000; Compensation Committee - $16,000; Nominating and Governance Committee - $15,000; Shareholders Communications Subcommittee - $10,000; and Cybersecurity Subcommittee - $10,000. Each non-employee director serving as a member of a committee of the Board (other than the chairperson) will receive an additional retainer as follows: Audit Committee - $12,000; Compensation Committee - $7,500; and Nominating and Governance Committee - $5,000. Non-employee directors will not receive any additional compensation for attending regular Board or committee meetings. However, with respect to special meetings of the Board or a committee, the Board shall determine whether such meetings will be eligible for payment of special fees, and if so, each non-employee director will receive $2,000 for a meeting attended in person and $1,000 for a meeting attended via teleconference.

Equity Grants: Each individual who is elected by the Company’s shareholders to serve as a non-employee director at the Company’s annual shareholders meeting and each individual who is to continue to serve as a non-employee director following such meeting whether or not that individual is standing for re-election at that meeting, will be granted on the date of such meeting, an award of restricted share units under the 2018 Omnibus Incentive Plan, as may be amended from time to time (the “2018 Plan”). The number of shares subject to each such annual award will be determined by dividing $170,000 by the Average Per Share Price, up to a maximum of 10,000 shares. The Average Per Share Price for an award means the average closing price per common share over the 90 day-period immediately prior to the date of grant of the award. The award will vest in four equal quarterly installments upon the non-employee director’s completion of each quarter of Board service following the grant date; provided, however, that if the Company’s annual shareholders meeting for the year following the year of grant occurs prior to the end of the one-year period measured from the grant date, the last quarterly installment will become vested upon the date of such subsequent annual shareholders meeting, provided that the non-employee director continues in Board service until such date. In the event a new non-employee director is elected or appointed to the Board on a date other than at the Company’s annual shareholders meeting, such individual will be granted on the date of such election or appointment, an award of restricted share units for a number of shares determined by dividing $170,000 as pro-rated based on the period from the date of election or appointment to the anticipated date of the next annual shareholders meeting by the Average Per Share Price, provided such individual has not previously been in the employ or service of the Company. The award shall vest on the same dates that the annual grants made at the preceding annual shareholders meeting vest with the number of shares vesting on each vesting date based on the period of service, with the number of shares vesting in substantially equal installments on each of the remaining vesting dates until the next annual shareholders meeting.

The awards (to the extent outstanding) will vest in full (i) upon the non-employee director’s termination of Board service by reason of death or permanent disability (as defined in the 2018 Plan) and (ii) immediately prior to the consummation of a change in control (as defined in the 2018 Plan). Shares that vest under an award on a quarterly vesting date or upon termination of Board service will be issued on the earlier of (i) the date of the annual shareholders meeting that is coincident with or next following the applicable vesting date or (ii) the date of the non-employee director’s termination of Board service. Shares that vest upon the consummation of a change in control will be issued as soon as practicable following the change in control.

Reimbursements: All non-employee directors receive reimbursement from the Company for their reasonable expenses of travel (including airfare and ground transportation) to and from meetings of the Board or a committee, and reasonable lodging and meal expenses.

EXECUTIVE COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

The Compensation Committee for fiscal year 2026 consisted of Dr. Lucas S. Chang, So-Yeon Jeong, Dr. King Owyang and Michael J. Salameh, and Dr. Lucas S. Chang resigned as a director on April 13, 2026. None of our Compensation Committee members has been an officer or employee of us or our subsidiaries at any time. None of our executive officers serves on the board of directors or compensation committee of any entity that has one or more executive officers serving as a member of our Board or our Compensation Committee.

PROPOSAL NO. 2

ADVISORY VOTE ON THE COMPENSATION OF THE NAMED EXECUTIVE OFFICERS

Under the Dodd-Frank Wall Street Reform and Consumer Protection Act, or the Dodd-Frank Act, and Section 14A of the Exchange Act, our shareholders are entitled to vote, on an advisory basis, to approve the compensation of our named executive officers as disclosed in this Proxy Statement in accordance with the rules of the SEC.

We design our executive compensation program to implement our core objectives of attracting and retaining superior executive talent, ensuring executive compensation is substantially dependent on our financial performance and provides incentives for the attainment of our key strategic business objectives and aligning executives’ incentives with the creation of shareholder value. The key elements of the compensation program that were in effect during the 2026 fiscal year for the Company’s named executive officers are described in detail in the Compensation Discussion and Analysis section of this Proxy Statement.

The vote on this proposal is not intended to address any specific element of compensation; rather the vote relates to the compensation of our named executive officers, as described in this Proxy Statement in accordance with the compensation disclosure rules of the SEC.

Although this vote is advisory and the outcome is not binding on our Board, the annual views expressed by our shareholders, whether through this vote or otherwise, are important to us. As a result, the Board and the Compensation Committee will carefully review the results of this vote, and they will consider these results in making future decisions about our executive compensation programs and arrangements.

The shareholders are being asked to approve by advisory vote the following resolution relating to the compensation of the named executive officers as described in this Proxy Statement:

“Resolved, that the Company’s shareholders hereby approve the compensation paid to the Company’s executive officers named in the Summary Compensation Table of this Proxy Statement, as that compensation is disclosed pursuant to Item 402 of Regulation S-K, including the Compensation Discussion and Analysis, the various compensation tables and the accompanying narrative discussion included in this Proxy Statement.”

Recommendation of the Board

The Board recommends that shareholders vote FOR the approval, on a non-binding, advisory basis, of the compensation of our named executive officers as disclosed in this Proxy Statement pursuant to the SEC’s compensation disclosure rules.

PROPOSAL NO. 3

APPROVAL OF AMENDMENT AND RESTATEMENT OF THE 2018 OMNIBUS INCENTIVE PLAN

We are asking our shareholders to approve an amendment and restatement of the Alpha & Omega Semiconductor Limited 2018 Omnibus Incentive Plan (the “2018 Plan”), which would increase the number of common shares authorized for issuance under the 2018 Plan by 1,170,000 shares to an aggregate of 6,372,000 shares and make certain other corresponding amendments. The Board approved the amendment and restatement of the 2018 Plan upon the recommendation our Compensation Committee to ensure that we can continue to grant equity awards and long-term incentives to our current and future officers, employees, non-employee directors, consultants and other independent advisors in our employ or service (or the employ or service of our affiliates).

In approving the amendment and restatement of the 2018 Plan, the Board made the following material changes, along with certain other conforming or clarifying revisions and non-substantive changes:

•increase the share reserve by 1,170,000 shares; and

•implement a corresponding increase to the number of shares that may be issued in settlement of exercised incentive stock options by an additional 1,170,000 shares.

The success of our business is dependent on our ability to motivate and retain our talented team to achieve important goals, and also to recruit top talent. We compete for talent in an industry and in geographic regions (including the Silicon Valley) where equity incentive compensation programs play a pivotal role in incentivizing and retaining key personnel. We believe that our continued ability to offer equity awards is a competitive necessity in our industry and is essential to recruiting and retaining the highly qualified technical and other key employees essential to our long-term growth and financial success, as well as rewarding and motivating current employees.

As of August 31, 2026, there were 366,370 common shares available for future grants under the 2018 Plan (i.e., after deducting shares subject to outstanding awards as of August 31, 2026). If this proposal is approved, the total number of authorized shares under the 2018 Plan will be increased by 1,170,000 shares to a total of 6,372,000, and the total number of shares available for future grants under the 2018 Plan will be approximately 1,536,370 shares. Although the number of shares required for our annual grants and other grants varies based on a number of factors, including our share price at the time of the grant and the size of individual grants awarded by our Compensation Committee, we do not believe that we have sufficient shares available under the 2018 Plan for our annual grants and other grants in fiscal year 2027 (the majority of which will be made during the first quarter of calendar year 2027) and beyond. Approval of this proposal is critical to sustaining our momentum as we build shareholder value. In this regard, our Board believes that if this proposal is not approved, we may be at a disadvantage against our competitors for recruiting, retaining and motivating individuals critical to our success and we could be forced to increase cash compensation to provide a market-competitive total compensation package necessary to attract, retain, and motivate the talent critical to our future successes. We do not believe this would be in our best interests or the best interests of our shareholders because these additional cash payments would, among other things, reduce resources available to meet our business needs and cause a loss of motivation by employees to achieve superior performance over a longer period of time. Equity-based incentives, by contrast, directly align a portion of the compensation of our service providers with the economic interests of our shareholders and meet the expected industry recruiting standards needed to enable us to attract, retain and motivate employees.

We are asking our shareholders to approve the amendment and restatement of the 2018 Plan in order to (i) meet NASDAQ listing requirements, (ii) allow incentive stock options awarded under the 2018 Equity Incentive Plan to meet the requirements of the Internal Revenue Code of 1986, as amended, and the regulations promulgated thereunder and (iii) conform to good corporate governance.

Plan Background

Our Board adopted the 2018 Plan on October 3, 2018 and our shareholders approved the 2018 Plan on November 8, 2018 (the “Plan Effective Date”). Our shareholders have subsequently approved increases to the share reserve under the 2018 Plan (at annual general meetings of our shareholders) as follows: 800,000 shares in 2019; 1,000,000 shares in 2021; 740,000 shares in 2022; 427,000 shares in 2023; 377,000 shares in 2024; and 593,000 shares in 2025.

The 2018 Plan is the only discretionary plan under which equity awards may be granted to our employees and other service providers. The 2018 Plan serves as the successor to our 2009 Share Option/Share Issuance Plan (the “Predecessor Plan”) which terminated following adoption of the 2018 Plan; while no further awards may be made under the Predecessor Plan, there are outstanding awards under the Predecessor Plan as described below.

Determination of Share Reserve Under 2018 Plan

If this proposal is approved, the total number of authorized shares under the 2018 Plan will be increased by 1,170,000 shares to a total of 6,372,000, and the total number of shares available for future grants under the 2018 Plan (i.e., after deducting shares subject to outstanding awards as of August 31, 2026) will be approximately 1,536,370 shares. In determining the number of shares to be authorized for issuance under the 2018 Plan, the Board considered a number of factors, including the number of shares remaining available for issuance under the 2018 Plan, our past share usage (burn rate), the number of shares needed for future awards and a dilution analysis.

Dilution Analysis

Our compensation philosophy reflects broad-based eligibility for equity awards. However, we recognize that equity awards dilute existing shareholders, and, therefore, we are mindful to responsibly manage the growth of our equity compensation program. We are committed to effectively monitoring our equity compensation share reserve relative to our industry and broader market norms to ensure that we maximize shareholders’ value by granting the appropriate number of equity awards necessary to attract, reward, and retain employees, non-employee directors and consultants and other independent advisors.

As of August 31, 2026, 366,370 shares were available for future awards under the 2018 Plan. No awards may be granted under the Predecessor Plan. As indicated in the table below, assuming shareholders approve the amendment and restatement of the 2018 Plan as set forth in this proposal, we expect to have a total of 1,536,370 shares available for issuance under the 2018 Plan.

The Company currently has awards outstanding under the 2018 Plan and the Predecessor Plan. As of August 31, 2026, there were 2,804,583 shares subject to time-based and performance-based restricted share unit awards under the 2018 Plan, and 255,500 shares subject to performance-based restricted share unit awards under the Predecessor Plan, as described in the table below. As of August 31, 2026, there were no outstanding options under either the 2018 Plan or the Predecessor Plan.


Plans as of August 31, 2026	Shares Subject to Outstanding Options	Shares Subject to Outstanding Full Value Awards (1)	Shares Available for Future Grant	Total Aggregate Shares
2018 Plan	—	2,804,583	366,370	3,170,953
Predecessor Plan (2)	—	255,500	—	255,500
Total (before amendment and restatement of the 2018 Plan is approved by the shareholders)	—	3,060,083	366,370	3,426,453
Shares Available for Future Grant Upon Approval of the amendment and restatement of the 2018 Plan by the shareholders (3)	—	—	1,536,370	4,596,453

(1) Consists of 1,601,645 shares subject to time-based restricted share units and 1,458,438 shares subject to performance-based restricted share units assuming target performance (which may settle in a range of 0% to 100% of target depending on level of performance attained).

(2) Consists of 255,500 shares subject to market-based restricted share unit awards. No additional awards may be granted under the Predecessor Plan.

(3) The share reserve may be adjusted as described in more detail in the section titled “Securities Subject to 2018 Plan” below.

We note that the number of shares remaining available for future grant as described above differs from those reported below under “Equity Compensation Plan Information,” because that table, required by SEC disclosure rules, is dated as of June 30, 2026, and therefore does not take into account vesting events and grants between July 1, 2026 and August 31, 2026.

Based on the Company’s common shares outstanding as of August 31, 2026, the additional 1,170,000 shares under the 2018 Plan represents an overhang of approximately 3.5% of our fully diluted shares. The Company calculates “fully diluted shares” as the total number of shares outstanding plus shares underlying outstanding awards and shares available for issuance under future equity awards.

Our Board believes that the number of shares under the 2018 Plan (as proposed to be increased) represents a reasonable amount of potential equity dilution, which will allow the Company to continue to grant equity awards which are an important component of our compensation program.

Burn Rate

In connection with our share-based compensation programs, we are committed to using equity incentive awards prudently and within reasonable limits. Accordingly, we closely monitor our share award “burn rate” each year. Our annual burn rate is determined by dividing the number of our common shares subject to time-based restricted share unit awards (“RSUs”) we grant, or the number of our common shares vested in the case of performance-based restricted share unit awards (“PSUs”) and market-based restricted share unit awards (“MSUs”), in a fiscal year by the weighted average number of our common shares outstanding for that fiscal year.


Fiscal Year	RSUs Granted	PSUs/MSUs Vested	Withholding Tax for RSUs/PSUs/MSUs Vested	Total RSU Granted or Vested if PSUs/MSUs	Weighted Average Common Share Outstanding	Burn Rate
2026(1)	874,131	406,308	(335,189)	945,250	30,253,076	3.1%
2025(2)	655,738	403,910	(327,793)	731,855	29,405,090	2.5%
2024	679,993	398,632	—	1,078,625	28,236,084	3.8%



3-Year	736,621	402,950	(220,994)	918,577	29,298,083	3.1%

(1) For fiscal year 2026, the table above excludes (a) 148,020 shares from the number of PSUs/MSUs vested, representing the number of shares withheld to cover taxes upon vesting of PSUs and MSUs during the period from November 2025 through June 2026 and (b) 187,169 shares from the RSUs vested during the period from November 2025 through June 2026. Commencing in November 2024, any shares that are withheld to satisfy tax withholding obligations will not be added back to the share reserve under the 2018 Plan and will not become available for future grants under the 2018 Plan; we therefore excluded such shares from the numerator of the burn rate calculation to more effectively demonstrate our burn rate.

(2) For fiscal year 2025, the table above excludes (a) 152,024 shares from the number of PSUs/MSUs vested, representing the number of shares withheld to cover taxes upon vesting of PSUs and MSUs during the period from November 2024 through June 2025 and (b) 175,769 shares from the RSUs vested during the period from November 2024 through June 2025. Commencing in November 2024, any shares that are withheld to satisfy tax withholding obligations will not be added back to the share reserve under the 2018 Plan and will not become available for future grants under the 2018 Plan; we therefore excluded such shares from the numerator of the burn rate calculation to more effectively demonstrate our burn rate.

The following table shows the number of common shares subject to PSUs and MSUs granted and vested in each fiscal year:

1. Represents MSUs granted in July 2018

2. Represents MSUs granted in December 2021

The number of shares to be ultimately earned under the fiscal year 2026, 2025, and 2024 PSUs is determined based on the level of attainment of predetermined financial goals (not to exceed the target number of shares). Any shares earned based on performance vest in four equal annual installments after the end of the performance period based on continued service.

The number of shares to be ultimately earned under the fiscal year 2022 MSUs (as amended in August 2024 and August 2026) is determined based on the Company’s achievement of specified stock prices and revenue thresholds during the performance period from September 19, 2023 to December 31, 2026. Any shares earned under the 2022 MSUs based on performance vest in four equal annual installments commencing January 1, 2027, subject to continued service. No executive officers are participants of the fiscal year 2022 MSU program.

The number of shares earned under the fiscal year 2019 MSUs was determined based on the Company’s achievement of specified stock prices and revenue thresholds during the performance period from January 1, 2019 to December 31, 2022. The shares earned under the 2019 MSUs based on performance vest in four equal annual installments commencing January 1, 2023, subject to continued service.

Based on our current equity award practices, our Board estimates that the authorized shares under the 2018 Plan (as proposed to be increased) may be sufficient to provide us with an opportunity to grant equity awards for approximately one year, in amounts determined appropriate by our Compensation Committee, which administers the 2018 Plan (as discussed below). This is only an estimate, and circumstances could cause the share reserve to be used more quickly or more slowly. These circumstances include, but are not limited to, the future price of our common shares, the mix of options and full value awards provided as long-term incentive compensation, grant amounts provided by our competitors, payout of performance-based awards in excess of target in the event of superior performance, hiring activity, and promotions during the next few years.

Highlights of the 2018 Plan

The 2018 Plan contains a number of provisions that we believe are consistent with best practices in equity compensation and which protect the shareholders’ interests, as described below.

No evergreen authorization: The 2018 Plan does not have an evergreen provision, which would have permitted an increase in the share pool without further shareholder approval.

No liberal share recycling: Any shares that are withheld by the Company or tendered by a participant to satisfy tax withholding obligations or to pay the exercise price of an option and any shares that are subject to a share appreciation right granted under the 2018 Plan that are not issued upon the exercise of such award will not be added back to the share reserve and will not become available for future grants under the 2018 Plan.

No automatic vesting upon a change in control: The 2018 Plan allows for an acquiring corporation to assume outstanding awards, and if awards are assumed, they will generally not accelerate on the change in control. If awards are not assumed, the vesting of such awards will be accelerated (with performance-based awards vesting based on actual performance attainment as of the date of the change in control or on a pro-rated basis for time elapsed in the ongoing performance period based on target level). The plan administrator also has the discretion to take alternative actions such as accelerating the vesting of outstanding awards on a termination following a change in control or requiring that participants exchange outstanding awards for cash.

No liberal change-in-control definition: A change in control is narrowly defined under the 2018 Plan in order to avoid windfall compensation without the occurrence of an actual change in control of the Company. As such, the 2018 Plan defines a change in control based on the consummation of the transaction rather than the announcement or shareholder approval of the transaction. A change in control is not triggered by shareholder approval or announcement of a transaction, a change in less than half of the Board, or an acquisition of a low percentage of common stock. Instead, the 2018 Plan defines a change in

control as (i) the consummation of a merger, consolidation or other reorganization approved by our shareholders, unless our shareholders continue to own more than fifty percent (50%) of the total combined voting power of the voting securities of the successor corporation; (ii) the consummation of a shareholder-approved sale of all or substantially all of our assets; (iii) the acquisition by any person or related group of persons of more than fifty percent (50%) of the total combined voting power of our outstanding securities; or (iv) a change in a majority of the Board over a twelve (12)-month period, unless the Board members have been approved by the incumbent Board.

Prohibition on repricings: The 2018 Plan prohibits the repricing of options or share appreciation rights, the cancellation and replacement of options or share appreciation rights with a grant with a lower exercise price, or a buyout of an underwater option or share appreciation right (except as permitted in a change in control or in the case of a corporate transaction as described in the section titled “Changes in Capitalization” below).

Minimum vesting requirements: The 2018 Plan provides that awards granted under the 2018 Plan that are payable in shares may vest no earlier than the first anniversary of the grant date, subject to certain exceptions set forth in the 2018 Plan, as described below.

No discounted options or share appreciation rights: Options and share appreciation rights must have an exercise price at or above fair market value per share on the date of grant.

Limit on director pay: The maximum aggregate grant date fair value (computed as of the date of grant in accordance with applicable financial accounting rules) of all awards made to a non-employee director under the 2018 Plan in a single calendar year, taken together with any cash payments (including the annual retainer and any other compensation) paid to such non-employee director in respect of such calendar year, shall not exceed $750,000 ($1,000,000 in the initial year of election or appointment) in total value.

No tax gross-ups: The 2018 Plan does not provide for any tax gross-ups.

Limitation on dividends and dividend equivalents: Any dividends or dividend equivalents payable in connection with an award will be subject to the same restrictions as the underlying award and will not be paid until and unless such award vests.

Administered by an independent committee: The 2018 Plan is administered by the Compensation Committee of our Board of Directors, which consists entirely of independent directors. The Compensation Committee may delegate its authority to a subcommittee or officer, as described in more detail below.

Summary Description of 2018 Omnibus Incentive Plan

The principal terms and provisions of the amended and restated 2018 Plan are set forth below. The summary, however, is not intended to be a complete description of all the terms of the 2018 Plan and is qualified in its entirety by reference to the complete text of the amended and restated 2018 Plan, filed with this Proxy Statement as Appendix A.

Types of Awards. The following types of awards may be granted under the 2018 Plan: options, share appreciation rights, share awards, restricted share units, dividend equivalent rights and other share-based awards. The principal features of each type of award are described below.

Administration. The Compensation Committee has the exclusive authority to administer the 2018 Plan with respect to awards made to our executive officers and non-employee directors and has the authority to make awards under the 2018 Plan to all other eligible individuals. However, our Board may at any time appoint a secondary committee of one (1) or more members of the Board to have separate but concurrent authority with the Compensation Committee to make awards under the 2018 Plan to individuals other than executive officers and non-employee directors. The Board or the Compensation Committee may also delegate authority to administer the 2018 Plan with respect to individuals other than executive officers and non-employee directors to one or more officers of the Company.

The term “plan administrator,” as used in this summary, will mean our Compensation Committee, the Board, any secondary committee and any delegates thereof, to the extent each such entity or person is acting within the scope of its administrative authority under the 2018 Plan.

Eligibility. Officers and employees, non-employee directors, as well as consultants and other independent advisors, in our employ or service or in the employ or service of our affiliates (whether now existing or subsequently established) are eligible to participate in the 2018 Plan. As of August 31, 2026, approximately 2,515 employees (including 4 executive officers and 1

employee director), 6 non-employee directors were eligible to participate in the 2018 Plan. For purposes of the 2018 Plan, an affiliate means a parent corporation or any entity in which the Company has an equity interest.

Securities Subject to 2018 Plan. Subject to the capitalization adjustments and the add back provisions related to outstanding awards, each as described below, if this proposal is approved, an aggregate of up to 6,372,000 shares shall be reserved for issuance under the 2018 Plan.

Shares subject to outstanding awards under the 2018 Plan and awards granted under the Predecessor Plan that expire, are forfeited or cancelled or otherwise terminate prior to the issuance of the shares subject to those awards or are settled in cash will be available for subsequent issuance under the 2018 Plan.

In addition, the following share counting procedures will apply in determining the number of common shares available from time to time for issuance under the 2018 Plan:

•Should the exercise price of an option or any withholding taxes incurred in connection with the exercise of an option or share appreciation right granted under the 2018 Plan be paid in common shares (whether through the withholding of a portion of the otherwise issuable shares or through tender of actual outstanding shares), then in each such case, the tendered or withheld shares will not be added to the shares reserved for issuance under the 2018 Plan.

•Should common shares be withheld by us, or if shares are tendered by the participant, in each case in satisfaction of the withholding taxes incurred in connection with the issuance, vesting or settlement of an award (other than an option or share appreciation right) granted under the 2018 Plan or the Predecessor Plan, then in each case the number of shares so tendered or withheld will not be added to the common shares available for issuance under the 2018 Plan.

•Upon the exercise of any share appreciation right granted under the 2018 Plan, the share reserve will be reduced by the gross number of shares subject to the award.

If this proposal is approved, the maximum number of common shares which may be issued pursuant to options intended to qualify as incentive stock options under the federal tax laws shall be limited to 6,372,000.

The plan administrator may grant awards in assumption of, or in substitution for, outstanding awards previously granted by an entity acquired by the Company or with which the Company combines. Such substitute awards will not reduce the common shares authorized for issuance under the 2018 Plan (but will count against the aggregate number of incentive stock options available for awards, as described above). Additionally, subject to applicable stock exchange requirements, if the acquired company’s equity plan has shares available, such shares may be available for grant under the 2018 Plan, which will not reduce (or be added back to) the shares authorized for issuance under the 2018 Plan.

The common shares issuable under the 2018 Plan may be made available from our authorized but unissued common shares or from common shares that we acquire, including shares purchased on the open market.

Participant Award Limits. The maximum number of common shares which may be issued pursuant to awards that are settled in shares and granted to any person under the 2018 Plan in any fiscal year shall not exceed 800,000 shares.

In addition, the maximum aggregate grant date fair value (computed as of the date of grant in accordance with applicable financial accounting rules) of all awards made to a non-employee director under the 2018 Plan in a single calendar year, taken together with any cash payments (including the annual retainer and any other compensation) paid to such non-employee director in respect of such calendar year, shall not exceed $750,000 ($1,000,000 in the non-employee director’s initial year of election or appointment) in total value.

Vesting Requirements. Awards granted under the 2018 Plan that are payable in shares may vest no earlier than the first anniversary of the grant date, provided that such minimum vesting requirement will not apply to (i) awards with respect to a maximum of 5% of the total number of shares available for issuance under the 2018 Plan as of the date of the Annual Meeting (including the 1,170,000 new shares if this proposal is approved by the shareholders), (ii) substitute awards, (iii) shares delivered in lieu of fully vested cash-based obligations, and (iv) awards granted to non-employee directors that vest on the earlier of the one-year anniversary of the grant date and the next annual shareholder’s meeting that is a last 50 weeks after the prior year’s annual meeting.

Awards. The plan administrator has complete discretion to determine (a) which eligible individuals are to receive awards, (b) the type, size, terms and conditions of the awards to be made, (c) the time or times when those awards are to be granted, (d)

the number of shares or amount of payment subject to each such award, (e) the time when the award is to become exercisable, (f) the status of any granted option as either an incentive stock option or a non-statutory option under the federal tax laws, (g) the maximum term for which the award is to remain outstanding, (h) the vesting and issuance schedules applicable to the shares which are the subject of the award, (i) the cash consideration (if any) payable per share subject to the award and the form of payment in which the award is to be settled, (j) with respect to performance-based awards, the amount payable at one or more levels of attained performance, the payout schedule and the form of payment, (k) in the event of the participant’s death or disability, accelerate the vesting or exercisability of an award, and (l) in the event of the consummation of a change in control, take any action described under the paragraph “General Provisions – Change in Control” below as authorized by the 2018 Plan.

Share Options. Each granted option will have an exercise price per share determined by the plan administrator, but the exercise price will not be less than one hundred percent (100%) of the fair market value of the option shares on the grant date. No granted option will have a term in excess of ten (10) years. The shares subject to each option will generally vest in one or more installments over a specified period of service measured from the grant date or upon the achievement of pre-established performance objectives. However, one or more options may be structured so that they will be immediately exercisable for any or all of the option shares. The shares acquired under such immediately exercisable options will be subject to repurchase by us, at the lower of the exercise price paid per share or the fair market value per share at the time of repurchase, if the optionee ceases service prior to vesting in those shares. Payment of the exercise price may be paid in one or more of the following forms as determined by the plan administrator: cash, our common shares, through a cashless exercise procedure pursuant to which the optionee effects a same-day exercise of the option and sale of the purchased shares through a broker in order to cover the exercise price for the purchased shares and the applicable withholding taxes and/or through a net exercise procedure pursuant to which we withhold a number of shares otherwise issuable upon exercise of the option having a value equal to the exercise price and applicable withholding taxes.

Upon cessation of service, the optionee will have a limited period of time in which to exercise his or her outstanding options to the extent exercisable for vested shares. The plan administrator has complete discretion to extend the period following the optionee’s cessation of service during which his or her outstanding options may be exercised.

Share Appreciation Rights. The 2018 Plan allows the issuance of two types of share appreciation rights:

•Tandem share appreciation rights granted in conjunction with options, which provide the holders with the right to surrender the related option grant for an appreciation distribution from us in an amount equal to the excess of (i) the fair market value of the vested common shares subject to the surrendered option over (ii) the aggregate exercise price payable for those shares.

•Stand-alone share appreciation rights, which allow the holders to exercise those rights as to a specific number of our common shares and receive in exchange an appreciation distribution from us in an amount equal to the excess of (i) the fair market value of the common shares as to which those rights are exercised over (ii) the aggregate exercise price in effect for those shares. The exercise price per share may not be less than the fair market value per underlying common share on the date the stand-alone share appreciation right is granted, and the right may not have a term in excess of ten (10) years.

The appreciation distribution on any exercised share appreciation right will be paid in (i) cash, (ii) our common shares or (iii) a combination of cash and our common shares. Upon cessation of service with us, the holder of a share appreciation right will have a limited period of time in which to exercise that right to the extent exercisable at that time. The plan administrator has complete discretion to extend the period following the holder’s cessation of service during which his or her outstanding share appreciation rights may be exercised.

Repricing. The plan administrator may not implement any of the following repricing programs (except in the case of a corporate transaction as described in the section titled “Changes in Capitalization” below): (i) the cancellation of outstanding options or share appreciation rights in return for new options or share appreciation rights with a lower exercise price per share, (ii) the cancellation of outstanding options or share appreciation rights with exercise prices per share in excess of the then current fair market value per common share for consideration payable in cash, other awards or our equity securities (except in the event of the consummation of a change in control) or (iii) the direct reduction of the exercise price in effect for outstanding options or share appreciation rights.

Share Awards and Restricted Share Units. Our common shares may be issued under the 2018 Plan subject to performance or service vesting requirements established by the plan administrator without any cash outlay required of the recipient. Our common shares may also be issued under the 2018 Plan pursuant to restricted share units, which entitle the recipients to receive those shares upon the attainment of designated performance goals or the completion of a prescribed service

period or upon the expiration of a designated time period following the vesting of those units, including (without limitation), a deferred distribution date following the termination of the recipient’s service with us.

The plan administrator will have the discretionary authority to structure one or more such awards so that the common shares subject to those awards (or cash, as applicable) will vest only upon the achievement of certain pre-established corporate performance goals which may be based on one or more of the following criteria: (i) cash flow; (ii) earnings (including earnings before interest and taxes, earnings before taxes, earnings before interest, taxes, depreciation, amortization and charges for share-based compensation, earnings before interest, taxes, depreciation and amortization, and net earnings); (iii) earnings per share; (iv) growth in earnings or earnings per share; (v) share price; (vi) return on equity or average shareholder equity; (vii) total shareholder return or growth in total shareholder return either directly or in relation to a comparative group; (viii) return on capital; (ix) return on assets or net assets; (x) invested capital, required rate of return on capital or return on invested capital; (xi) revenue, growth in revenue or return on sales; (xii) income or net income; (xiii) operating income, net operating income or net operating income after tax; (xiv) profit, operating profit or net operating profit; (xv) operating margin or gross margin; (xvi) return on operating revenue or return on operating profit; (xvii) sales or bookings targets; (xviii) billings; (xix) expense or expense control and/or cost reductions; (xx) capital expenditure; (xxi) improvement in or attainment of working capital levels; (xxii) market share or penetration; (xxiii) debt reduction or debt levels (xxiv) project and product measures; (xxv) operation performance; (xxvi) systems and systems improvement; (xxvii) manufacturing; (xxviii) manufacturing efficiencies, improvement or variances; (xxix) delivery performance; (xxx) product and technology development; (xxxi) manufacturing and operational achievements; (xxxii) capacity utilization or milestones; (xxxiii) environmental goals or management; (xxxiv) market capitalization, (xxxv) application approvals, (xxxvi) litigation and regulatory resolution goals, (xxxvii) implementation, completion or attainment of key projects, (xxviii) product sales or milestones, (xxxix) budget comparisons, (xl) growth in shareholder value relative to the growth of a peer group or index; (xli) development and implementation of strategic plans and/or organizational restructuring goals; (xlii) development and implementation of risk and crisis management programs; (xli) improvement in workforce diversity; (xlii) compliance requirements and compliance relief; (xliii) productivity goals; (xliv) workforce management and succession planning goals; (xlv) economic value added (including typical adjustments consistently applied from generally accepted accounting principles required to determine economic value added performance measures); ( xlvi) contract win, renewal or extension; (xlvii) design win; (xlviii) delivery and/or design schedule; (xlix) development or milestones in new generation of products or technologies; (l) product technology or quality; (li) leadership metrics; recruiting and maintaining personnel, employee retention, measures of customer satisfaction, employee satisfaction or staff development; (li) development or marketing collaborations, formations of joint ventures or partnerships or the completion of other similar transactions intended to enhance the Company’s revenue or profitability or enhance its customer base; (lii) merger and acquisitions; and (liii) other similar criteria consistent with the foregoing. In addition, such performance criteria may be based upon the attainment of specified levels of the Company’s performance under one or more of the measures described above relative to the performance of other entities and may also be based on the performance of any of the Company’s business units or divisions or any parent or subsidiary. Each applicable performance goal may include a minimum threshold level of performance below which no award will be earned, levels of performance at which specified portions of an award will be earned and a maximum level of performance at which an award will be fully earned. Each applicable performance goal may be structured at the time of the award to provide for appropriate adjustment for one or more of the following items: (A) asset impairments or write-downs; (B) litigation or claim judgments or settlements; (C) the effect of changes in tax law, accounting principles or other such laws or provisions affecting reported results; (D) accruals for reorganization and restructuring programs; (E) the operations of any business acquired by the Company; (F) the divestiture of one or more business operations or the assets thereof; (G) the effects of any corporate transaction, such as a merger, consolidation, separation (including spin-off or other distributions of stock or property by the Company) or reorganization; (H) restructurings, discontinued operations, extraordinary items, and other unusual, infrequently occurring or non-recurring charges or events; (I) acquisitions or divestitures; (J) change in the corporate structure or capital structure of the Company; (K) an event either not directly related to the operations of the Company, parent, subsidiary, division, business segment or business unit or not within the reasonable control of management; (L) foreign exchange gains and losses; (M) a change in the fiscal year of the Company; (N) the refinancing or repurchase of bank loans or debt securities; (O) unbudgeted capital expenditures; (P) the issuance or repurchase of equity securities and other changes in the number of outstanding shares; (Q) conversion of some or all of convertible securities to common stock; (R) any business interruption event; (S) the cumulative effects of tax or accounting changes in accordance with GAAP; (T) the effect of changes in other laws or regulatory rules affecting reported results; and (U) any other adjustment consistent with the operation of the 2018 Plan. The Compensation Committee may also grant awards that are based on performance goals other than those set forth above.

Should the participant cease to remain in service while holding one or more unvested shares or should the performance objectives not be attained with respect to one or more such unvested shares, then those shares will be immediately subject to cancellation. Outstanding restricted share units will automatically terminate, and no common shares will actually be issued in satisfaction of those awards, if the performance goals or service requirements established for such awards are not attained.

Dividend Equivalent Rights. The plan administrator may provide a participant as part of an award (other than options or share appreciation rights) with dividends or dividend equivalents, payable in cash, common shares, or a combination of cash

and common shares, on such terms as determined by the plan administrator. However, any dividend or dividend equivalent will only be paid if the underlying award vests and will be subject to a risk of forfeiture to the same extent as the underlying award.

Other Share-Based Awards. Under the 2018 Plan, the plan administrator may grant other types of awards that are denominated in common shares to anyone eligible to participate in the 2018 Plan. The plan administrator will determine the terms and conditions of such awards.

New Plan Benefits

No awards have been granted that are contingent upon approval of this proposal by our shareholders at the Annual Meeting. Any awards following approval of this proposal to participants shall be at the discretion of the plan administrator. Accordingly, the benefits or amounts that may be received by or allocated to (i) each of the executive officers listed in the Summary Compensation Table, (ii) each of the nominees for election as a director, (iii) all non-employee directors as a group, (iv) all of our present executive officers as a group, and (v) all of our employees, including all other current officers, as a group under the 2018 Plan are not determinable at this time. However, pursuant to our non-employee director compensation policy described above, each individual who is elected to serve as a non-employee director at the Annual Meeting will be granted on the date of such meeting, an award of restricted share units covering a number of shares determined by dividing $170,000 by the average closing price per common share over the 90 day-period immediately prior to the date of grant of the award. For information with respect to awards in the 2026 fiscal year to our named executive officers, see the “Executive Compensation- Grants of Plan-Based Awards” section of this Proxy Statement and for information with respect to grants made in the 2026 fiscal year to our non-employee directors, see the “Compensation of Non-Employee Directors – Director Compensation for Fiscal Year 2026” section of this Proxy Statement.

General Provisions

Change in Control. In the event of the consummation of a change in control, the following provisions are in effect for all outstanding awards under the 2018 Plan, unless provided otherwise in an award agreement entered into with the participant:

•Each outstanding award may be assumed, substituted, replaced with a cash retention program that preserves the intrinsic value of the award and provides for subsequent payout in accordance with the same vesting schedule applicable to the award or otherwise continued in effect by the successor corporation.

•To the extent an award is not so assumed, substituted, replaced or continued, the award will automatically accelerate in full (with vesting of performance-based awards to be determined with reference to actual performance attained as of the change in control or on a pro-rated basis for time elapsed in the ongoing performance period based on target level).

•An award may provide that if the award is assumed or otherwise continued in effect in connection with a change in control, the shares subject to the award will automatically vest on an accelerated basis in the event the individual’s service with us or the successor entity is terminated within a designated period following the change in control.

•Unless the plan administrator establishes a different definition for one or more awards, a change in control will be deemed to occur for purposes of the 2018 Plan in the event (a) we are acquired by merger or asset sale, (b) there occurs any transaction pursuant to which any person or group of related persons becomes directly or indirectly the beneficial owner of securities possessing more than fifty percent (50%) of the total combined voting power of our outstanding securities, or (c) there is a change in the majority of the Board effected through one or more contested elections for board membership.

The 2018 Plan defines change in control based on the consummation of the transaction rather than the announcement or shareholder approval of the transaction.

Changes in Capitalization. In the event any change is made to the outstanding common shares by reason of any share split, share dividend, recapitalization, combination of shares, exchange of shares, spin-off transaction, extra-ordinary distribution (whether in cash, securities or other property) or other change in corporate structure effected without our receipt of consideration or should the value of our outstanding common shares be substantially reduced by reason of a spin-off transaction or extraordinary dividend or distribution or should there occur any merger, consolidation, reincorporation or other reorganization, equitable adjustments will be made to: (i) the maximum number and/or class of securities issuable under the 2018 Plan; (ii) the maximum number and/or class of securities for which incentive options may be granted under the 2018 Plan; (iii) the maximum number and/or class of securities for which any one (1) person may be granted common share-denominated awards under the 2018 Plan per fiscal year; and (iv) the number and/or class of securities and the exercise price per share in

effect for outstanding awards and the cash consideration (if any) payable per share. Such adjustments will be made in such manner as the plan administrator deems appropriate.

Valuation. The fair market value per common share on any relevant date under the 2018 Plan is deemed to be equal to the closing selling price per share on that date as determined on the NASDAQ Global Select Market. As of August 31, 2026, the fair market value of a common share determined on such basis was $24.66 per share.

Shareholder Rights and Transferability. No optionee has any shareholder rights with respect to the option shares until such optionee has exercised the option and paid the exercise price for the purchased shares. The holder of a share appreciation right will not have any shareholder rights with respect to the shares subject to that right unless and until such person exercises the right and becomes the holder of record of any common shares distributed upon such exercise. Options are not assignable or transferable other than by will or the laws of inheritance following optionee’s death, and during the optionee’s lifetime, the option may only be exercised by the optionee. However, the plan administrator may structure one or more non-statutory options under the 2018 Plan so that those options will be transferable during optionee’s lifetime to one or more members of the optionee’s family or to a trust established for the optionee and/or one or more such family members or to the optionee’s former spouse, to the extent such transfer is in connection with the optionee’s estate plan or pursuant to a domestic relations order. Stand-alone share appreciation rights will be subject to the same transferability restrictions applicable to non-statutory options.

A participant will have full shareholder rights with respect to any common shares issued to him or her under the 2018 Plan, whether or not his or her interest in those shares is vested. A participant will not have any shareholder rights with respect to the common shares subject to restricted share units until that award vests and the common shares are actually issued thereunder. However, dividend-equivalent units may be paid or credited, either in cash or in actual or phantom common shares, on outstanding restricted share units, subject to such terms and conditions as the plan administrator may deem appropriate. Notwithstanding the foregoing, any dividends or dividend equivalents payable in connection with an award will be subject to the same restrictions as the underlying award and will not be paid until and unless such award vests.

Withholding taxes. A participant shall be required to pay to the Company, and the Company shall have the right to withhold, from any cash, shares or other securities or property issuable under any award or from any other compensation, any required withholding or any other applicable taxes or other amounts due in respect of an award. The plan administrator may provide one or more holders of awards under the 2018 Plan with the right to have us withhold a portion of the shares otherwise issuable to such individuals in satisfaction of the withholding taxes to which they become subject in connection with the issuance, exercise or settlement of those awards. Alternatively, the plan administrator may allow such individuals to deliver previously acquired common shares in payment of such withholding tax liability.

Deferral Programs. The plan administrator may structure one or more awards so that the participants may be provided with an election to defer the compensation associated with those awards for federal income tax purposes.

The plan administrator may also implement a non-employee director retainer fee deferral program that allows the non-employee directors the opportunity to elect to convert the Board and Board committee retainer fees to be earned for a year into restricted share units that defer the issuance of the common shares that vest under those units until a permissible date or event under Internal Revenue Code Section 409A.

To the extent we maintain one or more separate non-qualified deferred compensation arrangements which allow the participants the opportunity to make notional investments of their deferred account balances in common shares, the plan administrator may authorize the share reserve under the Plan to serve as the source of any common shares that become payable under those deferred compensation arrangements.

Clawback / Forfeiture. All awards will be subject to any clawback, recoupment or other similar policy adopted by the Board, and any cash, common shares or other property or amounts due, paid or issued to a participant will be subject to the terms of such policy.

Amendment and Termination. Our Board may amend or modify the 2018 Plan at any time subject to shareholder approval to the extent required under applicable law or regulation or pursuant to the listing standards of the stock exchange on which our common shares are at the time primarily traded. Unless sooner terminated by our Board, the 2018 Plan will terminate on the earliest of (i) November 7, 2028, (ii) the date on which all shares available for issuance under the 2018 Plan have been issued as fully-vested shares or (iii) the termination of all outstanding awards in connection with certain changes in control or ownership.

Summary of Federal Income Tax Consequences

The following is a summary of the Federal income taxation treatment applicable to us and the participants who receive awards under the 2018 Plan.

Option Grants. Options granted under the 2018 Plan may be either incentive options, which satisfy the requirements of Section 422 of the Internal Revenue Code, or non-statutory options, which are not intended to meet such requirements. The federal income tax treatment for the two types of options differs as follows:

Incentive Options. No taxable income is recognized by the optionee at the time of the option grant, and no taxable income is recognized for regular tax purposes at the time the option is exercised, although taxable income may arise at that time for alternative minimum tax purposes. The optionee will recognize taxable income in the year in which the purchased shares are sold or otherwise made the subject of certain other dispositions. For Federal tax purposes, dispositions are divided into two categories: (i) qualifying, and (ii) disqualifying. A qualifying disposition occurs if the sale or other disposition is made more than two (2) years after the date the option for the shares involved in such sale or disposition is granted and more than one (1) year after the date the option is exercised for those shares. If the sale or disposition occurs before these two periods are satisfied, then a disqualifying disposition will result.

Upon a qualifying disposition, the optionee will recognize long-term capital gain in an amount equal to the excess of (i) the amount realized upon the sale or other disposition of the purchased shares over (ii) the exercise price paid for the shares. If there is a disqualifying disposition of the shares, then the excess of (i) the fair market value of those shares on the exercise date or (if less) the amount realized upon such sale or disposition over (ii) the exercise price paid for the shares will be taxable as ordinary income to the optionee. Any additional gain or loss recognized upon the disposition will be a capital gain or loss.

If the optionee makes a disqualifying disposition of the purchased shares, then we will be entitled to an income tax deduction, for the taxable year in which such disposition occurs, equal to the amount of ordinary income recognized by the optionee as a result of the disposition. We will not be entitled to any income tax deduction if the optionee makes a qualifying disposition of the shares.

Non-Statutory Options. No taxable income is recognized by an optionee upon the grant of a non-statutory option. The optionee will in general recognize ordinary income, in the year in which the option is exercised, equal to the excess of the fair market value of the purchased shares on the exercise date over the exercise price paid for the shares, and the optionee will be required to satisfy the tax withholding requirements applicable to such income. We will be entitled to an income tax deduction equal to the amount of ordinary income recognized by the optionee with respect to the exercised non-statutory option subject to the limit on deductibility of compensation under Section 162(m) of the Code as described below. The deduction will in general be allowed for our taxable year in which such ordinary income is recognized by the optionee.

Share Appreciation Rights. No taxable income is recognized upon receipt of a share appreciation right. The holder will recognize ordinary income in the year in which the share appreciation right is exercised, in an amount equal to the excess of the fair market value of the underlying shares on the exercise date over the exercise price in effect for the exercised right, and the holder will be required to satisfy the tax withholding requirements applicable to such income. We will be entitled to an income tax deduction equal to the amount of ordinary income recognized by the holder in connection with the exercise of the share appreciation right subject to the limit on deductibility of compensation under Section 162(m) of the Code as described below. The deduction will be allowed for the taxable year in which such ordinary income is recognized.

Share Awards. The recipient of unvested common shares issued under the 2018 Plan will not recognize any taxable income at the time those shares are issued but will have to report as ordinary income, as and when those shares subsequently vest, an amount equal to the excess of (i) the fair market value of the shares on the vesting date over (ii) the cash consideration (if any) paid for the shares. The recipient may, however, elect under Section 83(b) of the Internal Revenue Code to include as ordinary income in the year the unvested shares are issued an amount equal to the excess of (i) the fair market value of those shares on the issue date over (ii) the cash consideration (if any) paid for such shares. If the Section 83(b) election is made, the recipient will not recognize any additional income as and when the shares subsequently vest. We will be entitled to an income tax deduction equal to the amount of ordinary income recognized by the recipient with respect to the unvested shares subject to the limit on deductibility of compensation under Section 162(m) of the Code as described below. The deduction will in general be allowed for our taxable year in which such ordinary income is recognized by the recipient.

Restricted Share Units. No taxable income is recognized upon receipt of restricted share units. The holder will recognize ordinary income in the year in which the shares subject to the units are actually issued to the holder. The amount of that income will be equal to the fair market value of the shares on the date of issuance, and the holder will be required to satisfy the tax withholding requirements applicable to such income. We will be entitled to an income tax deduction equal to the amount of ordinary income recognized by the holder at the time the shares are issued subject to the limit on deductibility of compensation

under Section 162(m) of the Code as described below. The deduction will be allowed for the taxable year in which such ordinary income is recognized.

Dividend Equivalent Rights. No taxable income is recognized upon receipt of a dividend equivalent right award. The holder will recognize ordinary income in the year in which a dividend or distribution, whether in cash, securities or other property, is paid to the holder. The amount of that income will be equal to the fair market value of the cash, securities or other property received, and the holder will be required to satisfy the tax withholding requirements applicable to such income. We will be entitled to an income tax deduction equal to the amount of the ordinary income recognized by the holder of the dividend equivalent right award at the time the dividend or distribution is paid to such holder. That deduction will be allowed for the taxable year in which such ordinary income is recognized.

Other Share-Based Award. In general, no taxable income is recognized upon receipt of other share-based awards. The holder will recognize ordinary income in the year in which the share-based awards are actually settled, and the participant will be required to satisfy the tax withholding requirements applicable to such income. We will be entitled to an income tax deduction equal to the amount of ordinary income recognized by the participant at the time of settlement subject to the limit on deductibility of compensation under Section 162(m) of the Code as described below. The deduction will be allowed for the taxable year in which such ordinary income is recognized.

Section 162(m) of the Code. Section 162(m) of the Code limits the deductibility for Federal income tax purposes of the compensation paid to certain executive officers to $1 million in a taxable year with respect to each such officer.

As in prior years, while deductibility of executive compensation for federal income tax purposes is among the factors the Compensation Committee considers when structuring our executive compensation arrangements, it is not the sole or primary factor considered. We retain the flexibility to authorize compensation that may not be deductible if we believe it is in the best interests of the Company.

Accounting Treatment. Pursuant to the accounting standards under FASB Accounting Standards Codification Topic 718, we will be required to determine the grant date fair value of all share-based equity awards, including grants of share options, share appreciation rights, share awards, restricted share units and all other share-based awards under the 2018 Plan. The total compensation cost of such equity awards will be amortized and charged to our reported earnings over the vesting period.

Required Vote

Provided a quorum is present, the affirmative vote of holders of a majority of the votes cast in person or represented by proxy and entitled to vote at the Annual Meeting will be required to approve the amendment and restatement of the 2018 Plan. Should such approval not be obtained, then the share reserve under the 2018 Plan will not be increased. However, awards will continue to be made under the 2018 Plan until the date all the common shares currently reserved for issuance thereunder have been issued or any earlier termination of the 2018 Plan.

Recommendation of the Board

The Board believes that Proposal 3 is in our best interests and in the best interests of our shareholders and recommends that shareholders vote FOR the approval of the amendment and restatement of the 2018 Plan.

Unless otherwise indicated thereon, the accompanying proxy will be voted FOR approval of the amendment and restatement of the 2018 Omnibus Incentive Plan.

PROPOSAL NO. 4

APPROVAL OF AMENDMENT OF THE 2018 EMPLOYEE SHARE PURCHASE PLAN

We are asking our shareholders to approve an amendment and restatement of the Alpha & Omega Semiconductor Limited 2018 Employee Share Purchase Plan (the “Purchase Plan”), which would increase by 2,000,000 common shares the total number of common shares authorized for issuance under the Purchase Plan. If this proposal is approved by our shareholders, the total shares available for issuance under the Purchase Plan would increase from 3,700,000 common shares to 5,700,000 common shares. The share reserve may be adjusted as described in more detail in the section titled “Securities Subject to the Purchase Plan below.

As of August 31, 2026, there were 475,658 common shares available for issuance under the Purchase Plan. Our Board of Directors believes that the currently available shares are insufficient to meet our future needs with respect to attracting, motivating and retaining employees in a competitive market for talent. Therefore, on or about September 10, 2026, our Board of Directors approved the increase in shares to be issued under the Purchase Plan from 3,700,000 common shares to 5,700,000 common shares, subject to shareholder approval at the Annual Meeting. In this regard, our Board of Directors believes that if this proposal is not approved, we may be at a disadvantage against our competitors for recruiting, retaining and motivating employees and we could be forced to increase cash compensation, thereby reducing resources available to meet our business needs.

We are asking our shareholders to approve the amendment of the Purchase Plan as required by the Internal Revenue Code.

Plan Background

Our Board of Directors adopted the Purchase Plan on October 3, 2018 and our shareholders approved the Purchase Plan on November 8, 2018 (the “Purchase Plan Effective Date”). Our shareholders have subsequently approved increases to the share reserve under the Purchase Plan (at annual general meetings of our shareholders) as follows: 1,070,000 shares in 2021 and 1,200,000 shares in 2023.

The Purchase Plan is designed to allow eligible employees of the Company and its participating parent and subsidiaries (whether now existing or subsequently established or acquired) to purchase common shares at designated intervals at a discount through their accumulated payroll deductions or other contributions.

The Purchase Plan is intended to qualify as an employee share purchase plan under Section 423 of the Internal Revenue Code of 1986, as amended (“Section 423”). Favorable tax treatment is available for United States tax residents participating in a Section 423 plan. The Purchase Plan also authorizes the grant of rights to purchase shares that do not qualify under Section 423 pursuant to offerings implemented by the plan administrator to achieve tax, securities law or other compliance requirements and objectives in particular locations outside of the United States.

The following is a summary of the principal features of the amended Purchase Plan. The summary, however, is not intended to be a complete description of the Purchase Plan and is qualified in its entirety by reference to the complete text of the Purchase Plan, filed with this Proxy Statement as Appendix B.

Administration

The Purchase Plan is administered by the Compensation Committee of the Board of Directors. Such committee, as plan administrator, has full authority to adopt administrative rules and procedures and to interpret the provisions of the Purchase Plan.

Securities Subject to the Purchase Plan

If this proposal is approved, the number of common shares reserved for issuance under the Purchase Plan will be 5,700,000 shares, subject to adjustments described below. The common shares issuable under the Purchase Plan may be made available from our authorized but unissued common shares or from common shares repurchased by the Company, including shares repurchased on the open market.

In the event any change is made to the common shares by reason of any share split, share dividend, recapitalization, combination of shares, exchange of shares, spin-off transaction, extraordinary distribution (whether in cash, securities or other property) or other change affecting the outstanding common shares as a class without the our receipt of consideration, or should the value of the outstanding common shares be substantially reduced as a result of a spin-off transaction or an extraordinary

dividend or distribution, then equitable adjustments shall be made to (i) the maximum number and class of securities issuable under the Purchase Plan, (ii) the maximum number and class of securities purchasable per participant on any one Purchase Date, (iii) the maximum number and class of securities purchasable in total by all participants on any one Purchase Date and (iv) the number and class of securities and the price per share in effect under each outstanding purchase right. The adjustments will be made in such manner as the plan administrator deems appropriate.

Offering Periods and Purchase Rights

Common shares are offered for purchase under the Purchase Plan through a series of successive offering periods which will be of such duration (not to exceed 27 months) as determined by the plan administrator. Unless otherwise specified by the plan administrator prior to the start of the applicable offering period, offering periods will commence on May 15 and November 15 (or if such dates are not trading days, then the first trading day immediately following such dates) and will be of a duration of approximately twenty-four (24) months. The initial offering period under the Purchase Plan commenced on November 15, 2018.

Each offering period will consist of one or more successive purchase intervals as determined by the plan administrator prior to the commencement of such offering period. Until such time as otherwise determined by the plan administrator, each offering period will be comprised of four (4) purchase intervals; purchase intervals will generally run from May 15 to November 14 each year and from November 15 each year to May 14 in the next year.

Should the fair market value per common share on any purchase date within an offering period be less than the fair market value per common share on the start date of that offering period, then the individuals participating in that offering period will, immediately after the purchase of our common share on their behalf on such purchase date, be transferred from that offering period and automatically enrolled in the new offering period commencing on the next business day following such purchase date, provided the fair market value per share on the start date of that new offering period is lower than the fair market value per common share on the start date of the offering period in which they were currently enrolled.

On the first day of each offering period, each participant will be granted a purchase right to acquire our common shares on the last day of the applicable purchase interval within the offering period, subject to certain limitations described below.

Eligibility and Participation

All employees of the Company or any participating parent or subsidiary corporation (whether any such corporation is currently a parent or subsidiary or subsequently acquired or is subsequently established at any time during the term of the Purchase Plan) will be eligible to participate in any offering period implemented under the Purchase Plan. The Purchase Plan currently provides that an employee of the Company or a participating parent or subsidiary who is employed on a basis under which he or she is regularly expected to work for more than twenty hours per week for more than five months per calendar year is eligible to participate in an offering period under the Purchase Plan. However, the plan administrator may waive one or both of the service requirements.

To participate in a particular offering period, an eligible employee must complete and file the requisite enrollment forms during the enrollment period for that offering period.

As of August 31, 2026, approximately 692 employees, including 4 executive officers, were eligible to participate in the Purchase Plan.

Contributions and Stock Purchases

Each participant may authorize contributions in any multiple of one percent up to a maximum of fifteen percent (or such other limit established by the plan administrator) of the base salary or cash earnings (as established by the plan administrator for an offering period) paid to the participant for the offering period.

Participants contribute to the Purchase Plan through payroll deductions or, if permitted, through other means specified by the plan administrator. Currently, contributions are permitted only through payroll deductions.

The accumulated contributions will automatically be applied to the acquisition of common shares on each purchase date (generally May 14 or November 14 each year). Accordingly, on each purchase date, each participant’s contributions accumulated for the purchase interval ending on that purchase date will automatically be applied to the purchase of whole and

fractional shares of common stock at the purchase price in effect for that purchase date. The first purchase under the Purchase Plan was May 14, 2019.

Purchase Price

The purchase price of the common shares acquired on each purchase date will not be less than eighty-five percent of the lower of the fair market value per share of the common shares on the first day of the offering period or the fair market value on the purchase date for that offering period.

The fair market value per common share on any particular date under the Purchase Plan is deemed to be equal to the closing selling price per share on such date on the NASDAQ Global Select Market (or if there is no closing price on such date, then the closing selling price per share on the last preceding date for which such quotation exists). On August 31, 2026, the fair market value of a common share determined on such basis was $24.66 per share.

Special Limitations

The Purchase Plan imposes certain limitations upon a participant’s rights to acquire common shares, including the following limitations:

•Purchase rights granted to a participant may not permit such individual to purchase more than $25,000 worth of our common shares (valued at the time each purchase right is granted) for each calendar year those purchase rights are outstanding at any time.

• Purchase rights may not be granted to any individual if such individual would, immediately after the grant, own or hold outstanding options or other rights to purchase, shares possessing five percent (5%) or more of the total combined voting power or value of all classes of our outstanding shares or the outstanding shares of any of the Company’s affiliates.

•No participant may purchase more than 875 common shares on any purchase date during any offering period and no more than 300,000 common shares may be purchased by all participants on any purchase date during any offering period (in each case subject to adjustment as indicated above).

The plan administrator will have the discretionary authority to increase or decrease the per participant and aggregate limitation as of the start date of any new offering period under the Purchase Plan, with the new limit to be in effect for that offering period. On August 12, 2021, the plan administrator approved an increase in the maximum number of common shares purchasable in total by all participants in the Purchase Plan on any one purchase date within the particular offering

period from 200,000 shares to 300,000 shares.

Termination of Purchase Right

The participant may withdraw from the Purchase Plan at any time prior to the next scheduled purchase date, and his or her accumulated contributions for the offering period in which that withdrawal occurs will at the participant’s election, either be applied to the purchase of shares on the next scheduled purchase date or be refunded immediately.

The participant’s purchase right will immediately terminate upon his or her cessation of employment or loss of eligible employee status. Any contributions which the participant may have made for the offering period in which such cessation of employment or loss of eligibility occurs will be refunded.

Shareholder Rights

No participant will have any shareholder rights with respect to the shares covered by his or her purchase rights until the shares are actually purchased on the participant’s behalf and the participant has become a holder of record of the purchased shares. No adjustment will be made for dividends, distributions or other rights for which the record date is prior to the date of such purchase.

Assignability

No purchase rights will be assignable or transferable by the participant, and the options will be exercisable only by the participant.

Change of Control

Should we be acquired by merger, or should there occur a sale of substantially all of our assets or of securities possessing more than fifty percent of the total combined voting power of our outstanding securities, or should there occur certain changes in the majority of our board of directors, all outstanding purchase rights will automatically be exercised immediately prior to the effective date of such change in control. The purchase price for any abbreviated offering period will be based on the purchase price formula in effect for the offering period in which such change in control occurs.

The limitation on the maximum number of shares purchasable by each participant (but not the limitation on all participants in the aggregate) on any one purchase date will be applicable to any purchase date attributable to such change in control.

Share Pro-Ration

Should the total number of common shares to be purchased pursuant to outstanding purchase rights on any particular date exceed the number of shares then available for issuance under the Purchase Plan, then the plan administrator will make a pro-rata allocation of the available shares on a uniform and nondiscriminatory basis, and the contributions of each participant, to the extent in excess of the aggregate purchase price payable for the common shares pro-rated to such individual, will be refunded.

Amendment and Termination

The Purchase Plan will terminate upon the earliest to occur of (i) November 14, 2028, (ii) the date on which all shares available for issuance thereunder are sold pursuant to exercised purchase rights or (iii) the date on which all purchase rights are exercised in connection with a change in control or ownership, unless terminated earlier by the plan administrator.

The plan administrator may alter or amend the Purchase Plan at any time. In no event may the plan administrator effect either of the following amendments or revisions to the Purchase Plan without the approval of the shareholders: (i) increase the number of shares of the common stock issuable under the Purchase Plan, except for permissible adjustments in the event of certain changes in the Company’s capitalization or (ii) modify the class of corporations that may be designated for participation in the Purchase Plan.

New Plan Benefits

The amendment to the Purchase Plan will not become effective unless it is approved by the shareholders at the 2026 annual meeting and no purchase rights have been granted under the Purchase Plan that are contingent upon approval of this proposal by our shareholders at the Annual Meeting.

Summary of Federal Income Tax Consequences

The Purchase Plan is intended to be an “employee stock purchase plan” within the meaning of Section 423. Under a plan which so qualifies, no taxable income will be recognized by a participant, and no deductions will be allowable to the company, upon either the grant or the exercise of the purchase rights. Taxable income will not be recognized until there is a sale or other disposition of the shares acquired under the Purchase Plan or in the event the participant should die while still owning the purchased shares.

If the participant sells or otherwise disposes of the purchased shares within two years after the start date of the offering period in which such shares were acquired or within one year after the purchase date of those shares, then the participant will recognize ordinary income in the year of sale or disposition equal to the amount by which the fair market value of the shares on the purchase date exceeded the purchase price paid for those shares, and the company will be entitled to an income tax deduction, for the taxable year in which such sale or disposition occurs, equal in amount to such excess.

If the participant sells or disposes of the purchased shares more than two years after the start date of the offering period in which the shares were acquired and more than one year after the purchase date of those shares, then the participant will recognize ordinary income in the year of sale or disposition equal to the lesser of (i) the amount by which the fair market value of the shares on the sale or disposition date exceeded the purchase price paid for those shares or (ii) fifteen percent (15%) of the fair market value of the shares on the start date of that offering period, and any additional gain upon the disposition will be taxed as a long-term capital gain. The company will not be entitled to an income tax deduction with respect to such sale or disposition.

If the participant still owns the purchased shares at the time of death, then the participant will recognize ordinary income at such time equal to the lesser of (i) the amount by which the fair market value of the shares on the date of death exceeds the purchase price or (ii) fifteen percent (15%) of the fair market value of the shares on the start date of the offering period in which those shares were acquired.

Foreign Taxation

The income tax consequences to participants in the Purchase Plan who are resident outside the U.S. will vary by country. Generally, those participants will be subject to taxation at the time the shares are purchased.

Summary of Accounting Treatment

Pursuant to Accounting Standards Codification Topic 718 of the Financial Accounting Standards Board, the grant date fair value of each option granted will be charged as a direct compensation expense to the Company’s reported earnings over the offering period to which that option pertains.

Required Vote

Provided a quorum is present, the affirmative vote of holders of a majority of the votes cast in person or represented by proxy and entitled to vote at the Annual Meeting will be required to approve the amendment of the Purchase Plan. Should such approval not be obtained, then the share reserve under the Purchase Plan will not be increased. However, awards will continue to be made under the Purchase Plan until the date all the common shares currently reserved for issuance thereunder have been issued or any earlier termination of the Purchase Plan.

Recommendation of the Board of Directors

The Board believes that Proposal 4 is in our best interests and in the best interests of our shareholders and recommends that shareholders vote FOR the approval of the amendment and restatement of the 2018 Employee Share Purchase Plan.

Unless otherwise indicated thereon, the accompanying proxy will be voted FOR approval of the amendment and restatement of the 2018 Employee Share Purchase Plan.

EXECUTIVE COMPENSATION

Compensation Discussion and Analysis

This Compensation Discussion and Analysis section discusses the compensation policies and arrangements that were in effect for the fiscal year ended June 30, 2026 for our chief executive officer, our chief financial officer, and our three most highly paid executive officers as determined under the rules of the SEC. Such individuals are referred to as our named executive officers. This discussion should be read together with the Summary Compensation Table and the other compensation tables and related disclosures that follow.

Fiscal Year 2026 Business and Financial Highlights

The Company is a designer, developer, and global supplier of a broad range of discrete power devices, wide band gap power devices, power management ICs and modules, including a wide portfolio of Power MOSFET, SiC, IGBT, IPM, TVS, HV Gate Drivers, Power IC, and Digital Power products. The Company differentiates itself by integrating its expertise in technology, design and advanced manufacturing and packaging to optimize product performance and cost. Its portfolio of products targets high-volume applications, including personal computers, graphic cards, game consoles, home appliances, power tools, smart phones, battery packs, consumer and industrial motor controls and power supplies for computers, servers and telecommunications equipment.

During the fiscal year ended June 30, 2026, the Company achieved several important financial, business and operational milestones, including the following:

•Recorded annual revenue of $678.9 million;

•Further strengthened our investment in R&D and developed over 70 new products and expanded our product portfolio, and progressed towards our objective of becoming a total power solution provider;

•Continued our focused growth strategy by solidifying our relationships with key Tier-1 customers and expanding our serviceable available markets, including additional design wins at Tier 1 customers that increased the percentage of our total revenues from Tier 1 customers; and

•Developed and continued to develop new products addressing the advanced computing market, which consists of AI, server, and graphics card, by leveraging our strength in client computing. Revenue of advanced computing increased 16.8% year-over-year; and

•Completed a $150 million sale transaction of equity interest in our JV company, which further enhanced our shareholders’ value and strengthened our financial positions.

Compensation Philosophy and Objectives

Our philosophy is to provide our named executive officers with compensation that will motivate and retain them, provide them with meaningful incentives to achieve and exceed short-term and long-term corporate objectives set by our Compensation Committee, and align their long-term interests with those of our shareholders.

Based on this philosophy, the compensation programs for our named executive officers are designed to achieve the following primary objectives:

•establish a compensation structure that is competitive enough to attract, retain and motivate outstanding executive talent;

•ensure that any cash incentive compensation programs for our named executive officers are aligned with our corporate strategies and business objectives by tying the potential payouts under such programs to the achievement of key strategic, financial and operational goals; and

•utilize long-term equity awards to further link pay to performance, align interests between our named executive officers and shareholders and promote retention.

Executive Compensation Practices

We strive to maintain sound governance standards and compensation practices and have incorporated many best practices into our fiscal year 2026 compensation programs, including the following:


WHAT WE DO
Align our executive pay with performance						Maintain a clawback policy to recoup cash and equity incentive compensation
Impose a 1 year post-vesting holding period on shares issued to our chief executive officer						Hold an annual “say-on-pay” advisory vote
Set challenging performance objectives for our performance-based equity awards and annual cash bonus plan						Maintain robust share ownership guidelines for our executive officers and Board members
Use multi-year vesting periods for our equity awards						Prohibit hedging and pledging of Company common stock
Place a substantial majority of executive pay at risk						Maintain an independent compensation committee
Cap annual cash bonus and long-term performance-based equity award payouts						Regularly evaluate our peer group and pay positioning
•Set pre-established grant dates for executive officers’ annual equity awards						Annually assess risks in our compensation programs


WHAT WE DON’T DO
X Offer contracts with multi-year guaranteed salary or bonus increases						X Offer guaranteed retirement benefits or non-qualified deferred compensation plans
X Provide tax gross-ups except in connection with certain perquisites						X Provide excessive perquisites
X Time the release of material non-public information to affect the value of executive compensation

CEO Post-Vesting Holding Requirement

For full value awards (i.e., share awards, performance share awards, restricted share units, and performance share units) granted to our Chief Executive Officer beginning on or after August 7, 2025, there is a one-year post-vesting holding requirement that requires the Chief Executive Officer to hold at least 50% of the common shares issued to the Chief Executive Officer under such full value awards (i.e., share awards, performance share awards, restricted share units, and performance share units), net of any common shares withheld to cover applicable taxes, for a period of one-year following the vesting date (the “Holding Period”). However, the Holding Period will not apply after a change in control, termination of service, or the date of the Chief Executive Officer’s death or disability. This post-vesting Holding Period, along with the common share ownership requirement described below, focuses the Chief Executive Officer on the long-term success of the Company and further aligns the executive officer’s interests with those of our shareholders.

Impact of 2025 Say-on-Pay Vote

We held our last “say on pay” vote in 2025 and approximately 98.6% of the total votes cast on such proposal were in favor of the compensation of the named executive officers, as that compensation was disclosed in the Compensation Discussion and Analysis and the various compensation tables and narrative that appeared in the Company’s proxy statement dated September 18, 2025. Based on that high level of shareholder approval, the Compensation Committee decided not to make any material changes to the Company’s compensation philosophies, policies and practices for the fiscal year 2026 compensation of the named executive officers.

The Compensation Committee will continue to take into account future shareholder advisory votes on executive compensation and other relevant market developments affecting executive officer compensation in order to determine whether any subsequent changes to the Company’s executive compensation programs and policies would be warranted to reflect any shareholder concerns reflected in those advisory votes or to address market developments.

Compensation Decision-Making Process

The Compensation Committee meets on a regular schedule throughout the year to manage our compensation programs. The Compensation Committee reviews the principal components of compensation for our executive officers on an annual basis, typically at its first meeting in the calendar year. As part of that review process, the Compensation Committee reviews and may adjust the base salaries of our named executive officers, establishes the cash bonus plan for the

year and determines the cash bonuses payable to our named executive officers for the preceding year based on achievement of the pre-specified performance goals for that prior year and grants equity awards to our named executive officers.

In setting executive compensation, the Compensation Committee takes into account a number of factors, including the nature and scope of the named executive officer’s responsibilities, his or her individual performance level and contribution to the achievement of our corporate objectives, the experience level of the executive, the recommendations from its compensation consultant, the recommendations from our Chief Executive Officer for each executive’s compensation package (other than his own), the results of the last “say on pay” vote and the compensation trends in the industry.

Role of Compensation Consultant

The Compensation Committee retained Compensia to advise the committee on the compensation for executive officers and other senior officers for fiscal year 2026 and to develop a peer group that represents companies that are comparable in business and/or size to the Company and with which the Company competes for talent. Compensia recommended a revised peer group for fiscal year 2026 as compared to its fiscal year 2025 peer group. Based on such recommendation, the Compensation Committee approved the peer group set forth below. The peer group was used primarily in connection with a review of competitive compensation for our Chief Executive Officer and Chief Financial Officer.

Form Factor	Power Integrations	Wolfspeed
Ichor Holdings, Ltd.	Semtech	Indie Semiconductor

In January 2026, Compensia provided the Compensation Committee with compensation data based on the peer group companies for our Chief Executive Officer and our Chief Financial Officer. With respect to all officers, Compensia provided Radford survey data for public companies with revenues in the range of $200 million to $1.5 billion supplemented by data from its own database. Compensia also provided an analysis with respect to market positioning and the cost to bring the compensation of our named executive officers to various levels of market.

Our Compensation Committee reviewed and considered the 2026 Compensia report and analysis in connection with establishing base salary, bonus potential and equity awards for fiscal year 2026 but relied on its own judgment and experience in establishing and adjusting executive compensation for fiscal year 2026.

For a discussion of the specific responsibilities of our Compensation Committee, see "Board of Directors and Committees of the Board - Committees of the Board - Compensation Committee” above.

Role of Management

Our Chief Executive Officer, with input from our Vice President of Human Resources, provides our Compensation Committee with his recommendations as to the base salary, cash bonus potential and equity incentive award for each of our named executive officers other than himself based on that executive’s level of responsibility, individual performance and contribution to the attainment of our strategic corporate objectives and market data. Our Compensation Committee takes the Chief Executive Officer’s recommendations into consideration in setting named executive officer compensation, but retains complete discretionary authority to make all compensation-related decisions for our named executive officers. Our Compensation Committee makes its compensation decisions with respect to the Chief Executive Officer on the basis of relevant market data furnished by Compensia and its subjective assessment of his individual performance and contributions to our overall corporate performance. Any decisions regarding our Chief Executive Officer's compensation are made without him present.

Compensation Structure

Elements of Compensation

We utilize three main components in structuring compensation programs for our named executive officers:

•Base salary, which is the only fixed compensation element in our executive compensation program and is primarily used to recruit and retain executive talent and provide an element of economic security from year to year;

•Annual performance-based cash bonuses that are primarily designed to reward achievement of short-term financial and operational goals; and

•Equity incentive awards designed to ensure long-term retention of our executive talent and align their interests with those of our shareholders.

We further align the interests of our executives and those of our shareholders and the long-term interests of the Company through:

•our stock ownership requirements; and

•the post-vesting holding period requirement for shares issued to our Chief Executive Officer upon vesting of full value awards (i.e., share awards, performance share awards, restricted share units, and performance share units), as described above in the section titled “Executive Compensation Practices– CEO Post-Vesting Holding Requirement”

We view each component of compensation as related but distinct. It is the practice of our Compensation Committee to allocate a substantial portion of each named executive officer’s total compensation to performance and long-term incentive compensation as a result of the philosophy described above. There is no pre-established policy for the allocation of compensation between cash and non-cash components or between short-term and long-term components, and there are no pre-established ratios between the compensation of our Chief Executive Officer and that of the other named executive officers. Instead, our Compensation Committee determines the compensation of each named executive officer based on its review of the market data provided by Compensia, its subjective analysis of that executive’s performance and contribution to our financial performance, the executive’s relative criticality to the Company and the other factors identified in the Compensation Decision-Making Process section above to determine the appropriate level and balance of total compensation. We believe that this approach allows us to tailor compensation for each named executive officer to attract, retain and motivate that executive officer within the parameters of our compensation philosophy.

Base Salaries

Base salaries are set at levels that are intended to recognize the experience, skills, knowledge and responsibilities required of all our named executive officers. Each named executive officer's base salary level is typically reviewed on an annual basis and adjustments may be made to the executive’s base salary on the basis of his or her level of performance, the overall performance of the Company and the various compensation trends in our industry.

In March 2026, the Compensation Committee approved salary adjustments over the fiscal year 2026. Additionally, in May 2026, the Compensation Committee approved an additional increase in Mr. Li’s base salary to reflect the expansion of his role and responsibilities. In approving the increase, the Compensation Committee considered the increased scope of Mr. Li’s responsibilities and the demands associated with his expanded role, and determined that an adjustment to his base salary was appropriate to better align his compensation with his current responsibilities.

The base salaries for the named executive officers effective July 1, 2026 (and May 18, 2026 for Mr. Li) were as follows:


Named Executive Officer	Annual Base Salary
Stephen C. Chang	$	519,841
Yifan Liang	$	392,533


Wenjun Li	$	383,963
Bing Xue	$	371,315

Annual Performance-Based Cash Bonuses

Our named executive officers are eligible to receive a cash bonus under our annual Executive Incentive Plan. Each year, our Compensation Committee establishes the performance objectives to be attained and the target bonuses payable based on the level of attainment of the specified goals. The bonus is determined on a calendar year basis with performance goals based on the Company’s annual operating plan which is established on a calendar year basis.

On February 28, 2025, the Compensation Committee approved the calendar year 2025 Executive Incentive Cash Bonus Plan (the “2025 Incentive Plan”), pursuant to which the named executive officers were eligible to receive a cash incentive award based on the level of attainment of specified Company performance goals. The aggregate amount of the

award was to determined based on the level of attainment of a range of non-GAAP earnings per share and revenue for the year. A specified minimum amount of each of the non-GAAP earnings per share and revenue goals must be achieved before payment of an award under the 2025 Incentive Plan. Because the lowest threshold for non-GAAP earnings per share and revenue were not achieved, no bonuses were paid in 2025.

On March 2026, the Compensation Committee approved the calendar year 2026 Executive Incentive Cash Bonus Plan (the “2026 Incentive Plan”), pursuant to which the named executive officers will be eligible to receive a cash incentive award based on the level of attainment of specified Company performance goals. The aggregate amount of the award will be determined based on the level of attainment of a range of non-GAAP earnings per share and revenue for the year. A specified minimum amount of each of the adjusted earnings per share and revenue goals must be achieved as a condition to payment of any award under the 2026 Incentive Plan.

The Compensation Committee believes that the adjusted earnings per share and revenue goals are the appropriate criteria for our performance-based compensation because they focus our executives on key goals for the success of our business. The revenue goal relates to the importance of growing the Company’s total revenues which is an important measure of success in our competitive industry and is helpful in showing the marketplace that our business has the size and scale required to serve large customers. The adjusted earnings per share goal ties to our corporate emphasis on increasing shareholder value through the improvement of the Company’s adjusted earnings per share. The Committee believes that the performance goals for the target bonus represent a significant degree of difficulty and the maximum bonus amount can only be earned if stretched goals are achieved.

The actual aggregate amount of the award earned by a named executive officer for the 2026 calendar year will range from $0 to the maximum amount established for that officer depending on the level of attainment of the performance goals. Assuming the minimum performance goals have been achieved, the minimum, target and maximum bonus payable to each named executive officer of the Company (as a percentage of base salary) are as follows:


Name	Minimum Bonus	Target Bonus	Maximum Bonus
Stephen Chang	23%	100%	220%
Yifan Liang	16%	70%	154%
Wenjun Li	16%	70%	154%
Bing Xue	16%	70%	154%

Long Term Equity Incentive Awards

Our equity award program is the primary vehicle for offering long-term incentives to our named executive officers and providing an inducement for long-term retention. Equity compensation represents a significant component of the total compensation package we provide to each of our named executive officers. We believe this is appropriate because it aligns the interests of our named executive officers with those of our shareholders and focuses their attention on the creation of shareholder value in the form of stock price appreciation. The Compensation Committee may use both options and restricted share units as part of the Company’s long-term incentive program for named executive officers, although in recent years, only restricted share units have been awarded to the named executive officers. The Company believes that there are several advantages of using restricted share units, including ongoing concerns over the dilutive effect of option grants on the Company’s outstanding shares, the Company’s desire to have a more direct correlation between the compensation expense it must record for financial accounting purposes and the actual value delivered to executive officers, and the fact that the incentive and retention value of a restricted share unit award is less affected by market volatility than options.

We grant both time-based restricted share units that vest based on continued service and performance-based restricted share units that vest based on the level of attainment of Company performance goals and continued service. The Compensation Committee believes that including performance-based restricted share units as part of our equity-based compensation program strengthens the executive’s focus on the Company’s financial performance and shareholder value creation and performance-based restricted share units now generally represent 50% each executive officers’ equity awards. For 2018, the performance-based restricted share unit awards granted to our named executive officers included market performance restricted share units that vest based on our long-term stock price performance with a multiplier based on revenue growth and a subsequent service period, which further focus our executives on long-term stock price appreciation.

Our Compensation Committee reviews our equity compensation program annually and may, at its discretion, grant additional equity awards to existing named executive officers consistent with our named executive officer compensation objectives. In determining the size of those additional grants, our Compensation Committee typically takes into account the recommendations of our Chief Executive Officer, data provided by (and recommendation of) Compensia and its own

subjective assessment of the named executive officer’s performance and the retention value of his or her existing equity awards.

A subcommittee comprised of our Chief Executive Officer and Chief Financial Officer is authorized to grant options and restricted share unit awards (other than annual refresher equity grant awards) to existing and newly-hired employees, other than executive officers, within prescribed caps established by the Compensation Committee. These grants are generally made on the 15th day of each month.

The awards granted to our named executive officers in fiscal year 2026 and previously granted awards that vested in fiscal year 2026 are summarized below. For more information concerning the awards we granted to our named executive officers in 2026, please see “Grants of Plan-Based Awards” below.

March 2026 Grants: On March 5, 2026, the Compensation Committee authorized, effective as of March 16, 2026, the grant of restricted share units to each of our named executive officers for the number of our common shares allocated between time-based restricted share units and performance-based restricted share units as indicated below.


Named Executive Officer	Time-Based Restricted Share Units (Shares)	Performance -Based Restricted Share Unit (Target Shares)
Stephen C. Chang	67,500	67,500

Yifan Liang	22,500	22,500

Wenjun Li	10,000	10,000

Bing Xue	15,000	15,000

Each time-based restricted share unit entitles the holder to receive one common share following vesting. Each such award will vest with respect to 25% of the units annually upon the participant’s completion of each year of service over the four-year period measured from March 16, 2026.

Each performance-based restricted share unit award will vest based on the level of attainment of revenue goals from specified strategic initiatives over the period January 1, 2026 to December 31, 2026 and the participant’s continued service over a four-year period measured from March 16, 2026. In addition to the multi-years market-based restricted share unit awards program, the Compensation Committee believes there are a number of benefits in structuring performance awards with a one-year performance period combined with a three-year service period. In particular, the Compensation Committee’s ability to reset performance objectives and tailor goals year over year in response to near-term changes in the Company’s performance or strategic goals, makes a one-year performance period more powerful as a tool for incentivizing consistent, exceptional performance.

The Compensation Committee believes the performance goals for the 2026 performance-based restricted share unit awards are challenging and difficult to achieve, but attainable with significant skill and effort on the part of the executive team. The Company discloses specific goals, and actual achievement, at the end of each performance period as the Compensation Committee has determined that disclosing all such levels at the beginning of the performance period could cause competitive harm to the Company.

Vesting of February 2025 Grants: On February 28, 2025, the Compensation Committee authorized, effective as of March 15, 2025, the grant of restricted share units to each of our named executive officers for the number of our common shares allocated between time-based restricted share units and performance-based restricted share units as indicated below.


Named Executive Officer	Time-Based Restricted Share Units (Shares)	Performance -Based Restricted Share Unit (Target Shares)
Stephen C. Chang	67,500	67,500

Yifan Liang	22,500	22,500

Wenjun Li	10,000	10,000

Bing Xue	15,000	15,000

Each time-based restricted share unit entitles the holder to receive one common share following vesting. Each such award vests with respect to 25% of the units annually upon the participant’s completion of each year of service over the four-year period measured from March 17, 2025. Accordingly, the time-based award vested with respect to 25% of the units on March 17, 2026.

Each performance-based restricted share unit award was to vest based on the level of attainment of specified non-GAAP earnings per share and revenue goals over the period January 1, 2025 to December 31, 2025 and the participant’s continued service over a four-year period measured from March 15, 2024. The applicable performance conditions were (1) if the Company achieves one Power IC design win in AI data center, 30% of the target number of units designated for each employee shall be eligible to vest, and (2) if the Company generates revenue related to two strategic accounts pre-defined by the Company, up to 70% of the target number of units designated for each employee shall be eligible to vest based on the amount of the revenue generated. In March 2026, based on the achievement of the design win and revenue for the performance period, the Compensation Committee determined that the performance goals had been attained at 100% of target.

Vesting of 2018 Market Performance Restricted Share Unit Grants: In 2018, the Compensation Committee approved a special grant of market performance-based restricted share unit awards to provide significant long-term incentives to directly align the interests of the executive officers with those of shareholders and at the same time to further enhance retention. Performance vesting was tied to share price performance over a 4-year period and revenue achieved in calendar year 2022. The number of earned shares is then subject to a 4-year service vesting commencing January 1, 2023. Accordingly, there is a 7-year combined performance and service vesting period applicable to each award.

The number of shares earned was to be determined upon completion of the performance period based on the highest average price of the Company’s common shares for any period of 20 consecutive trading days (“Average Company Price”) attained during the period January 1, 2019 to December 31, 2022, with $26.24 at threshold performance (representing an increase of 83% from the Average Company Price on the grant date) to $45.00 at target performance (representing a 214% increase from the Average Company Price on the grant date) and a multiplier based on the Company’s revenue for calendar year 2022 ranging from 0.5 at threshold revenue of $550 million and 1 for target revenue of $600 million.

In February 2023, based on the Average Company Price of $45.237 during the performance period and revenue of $794 million for 2022, the Compensation Committee determined that the market performance-based awards were earned at 100% of target.

The table below sets forth the target number of our common shares subject to the market performance-based restricted share units awarded to each of our named executive officers. Each officer vests in these shares in 4 equal installments upon completion of each year of service over the 4-year period measured from January 1, 2023. Accordingly, each named executive officer vested in 25% of the shares on January 1, 2026.


Named Executive Officer									Market Performance -Based Restricted Share Unit (Target Shares)
Stephen C. Chang									90,000

Yifan Liang									90,000

Wenjun Li									30,000

Bing Xue									90,000

Termination and Change in Control Benefits

We have entered into an employment agreement with Mr. Stephen C. Chang who became our Chief Executive Officer effective March 1, 2023, which sets forth certain terms and conditions governing his period of continued employment with us, including certain benefits to which he would become entitled were his employment to be terminated involuntarily. We have entered into an employment agreement with Dr. Mike F. Chang, who was our Chief Executive Officer until March 1, 2023 after which he served as our Executive Chairman of the Board until March 3, 2025 and now serves as Chairman of the Board and Executive Vice President of Strategic Initiatives, which sets forth certain terms and conditions governing his period of continued employment with us including certain benefits to which he would become entitled were his employment

to be terminated involuntarily. In addition, we have entered into retention agreements with each of Messrs. Liang, Li, and Xue pursuant to which such officers are entitled to certain severance benefits upon an involuntary termination of employment. Mr. Stephen C. Chang’s employment agreement, Dr. Mike F. Chang’s employment agreement, and the retention agreements for the other officers are summarized below in the section of this proxy entitled “Agreements Regarding Employment, Change in Control and Termination of Employment”.

Pursuant to the terms of our equity plans, outstanding options and time-based restricted share unit awards held by our named executive officers and our other employees will accelerate upon the consummation of a change in control unless those options or awards are assumed, replaced or otherwise continued by the acquiring entity. The performance-based restricted share unit awards (other than the market performance restricted share unit awards) will convert into the right to receive 50% of the target number of shares or the actual number of shares based on level of attainment of performance goals depending on when the change in control occurs and will be paid out at the time of the change in control unless those awards are assumed, replaced or otherwise continued by the acquiring entity. The performance qualified shares under the market performance restricted share unit awards (for which the performance period is already completed) will be paid out at the time of the change in control unless those awards are assumed, replaced or otherwise continued by the acquiring entity. Any awards that are assumed, replaced or otherwise continued will continue to vest over the service period for the award subject to accelerated vesting of the market performance share unit awards upon the executive officer’s involuntary termination within 18 months following the change in control (12 months for our named executive officers under their employment and retention agreements with respect to awards other than the market performance restricted share unit awards). The Compensation Committee believes that accelerated vesting under such a limited circumstance is appropriate because it protects a significant component of the named executive officer's total compensation in the event those options and awards would otherwise terminate in the acquisition or upon a subsequent involuntary termination and allows our named executive officers to remain focused on the Company’s business without undue concern over this significant component of their compensation package should the Company become an acquisition target in a transaction in which the outstanding equity awards would not be assumed or replaced or following which the named executive officer may be terminated.

Our severance and change of control provisions for the named executive officers are discussed in more detail in “Potential Payments upon Termination or Change in Control” below.

Benefits and Other Compensation

We maintain broad-based employee benefit plans, which are provided to all eligible employees, including our named executive officers. These plans provide group medical and dental coverage, life insurance, disability insurance, flexible spending accounts and a 401(k) savings program for our employees based in the United States. We believe these benefits are consistent with the benefits offered by companies with which we compete for employees and are necessary to attract and retain qualified employees.

Perquisites

We believe that cash and equity compensation are the key components needed to attract and retain our executive officers. As a result, we generally do not provide any substantial perquisites to our named executive officers.

Mr. Xue is provided a Company vehicle for his use in connection with his sales activities and other Company business and his personal use. He receives a payment of up to $10,000 each year to cover the taxes payable as a result of this benefit.

We also offer bonuses for patented inventions, authoring technical articles and making technical presentations at major symposiums; and long service; our named executive officers are eligible to receive bonuses under these programs on the same basis as our other employees. In fiscal year 2026, we also provided headphones and reimbursement for fitness membership fees to our named executive officers.

Stock Ownership Guidelines

We have adopted stock ownership guidelines for our executive officers and the non-employee members of our Board. Under these guidelines, each executive officer is required to own shares with a value equal to a specified multiple of his or her annual base salary and each non-employee member of our Board is required to own shares with a value equal to a specified multiple of his or her annual cash retainer for services on the Board and standing committees of the Board as follows:




Position						Specified Multiple

Chief Executive Officer						Three times base salary

Other Executive Officer						One times base salary

Board Member						Three times annual retainer

Shares that count towards satisfaction of the guidelines include shares beneficially owned by the individual or immediate family members, shares held in trust for the benefit of the individual or immediate family members and deferred shares subject to vested restricted share units or performance units and other vested equity awards. Unvested restricted share units, unvested performance units or restricted shares, and unexercised stock options do not count towards satisfaction of the guidelines.

Our executive officers and the non-employee members of our Board are required to meet these ownership requirements within five years of the later of (1) May 3, 2018 (the date of adoption of the guidelines) or (2) becoming an executive officer or non-employee member of our Board, as applicable. The Compensation Committee believes that this stock ownership aligns the financial interests of our executive officers with those of our shareholders.

The following table shows each named executive officer’s and each Board member’s share ownership as of June 30, 2026:


	Share Ownership ($) (1)	Share Ownership Guideline ($) (2)
Named Executive:
Stephen C. Chang	17,556,827	1,514,100
Yifan Liang	8,029,676	381,100
Wenjun Li	2,008,354	352,260
Bing Xue	2,066,428	360,500

Board Members:
Mike F. Chang	162,633,879	437,750
Claudia Chen	1,199,863	270,000

So-Yeon Jeong	991,989	202,500
Hanqing (Helen) Li	991,989	195,000
King Owyang	3,427,402	247,500
Michael J. Salameh	2,933,655	327,000

(1) This amount is calculated by multiplying (i) the sum of the Company’s common shares actually owned by (ii) $47.33, the closing selling price of the common shares on June 30, 2026.

(2) This amount is equal to three times the base salary in effect for Mr. Stephen C. Chang for the 2026 fiscal year, one times the base salary in effect for the other named executive officers for such year and three times the annual retainer for the non-employee Board members for such year.

Insider Trading, Anti-Hedging and Anti-Pledging Policies

We have adopted a Statement of Company Policy Regarding Insider Trading (the “Insider Trading Policy”) governing the purchase, sale and other dispositions of the Company’s securities that applies to all personnel of the Company and its subsidiaries, including directors, officers and employees and other covered persons. We believe that our Insider Trading Policy is reasonably designed to promote compliance with insider trading laws, rules and regulations, as well as applicable listing standards. Further, our Insider Trading Policy explicitly prohibits any director or employee, including our NEOs, from hedging their equity ownership in the Company by engaging in short sales or trading in any derivatives involving the Company’s securities without obtaining pre-clearance from our Chief Financial Officer or Chief Executive Officer. All employees are also prohibited from holding Company securities in a margin account or otherwise pledging Company securities or using financial instruments such as prepaid variable forwards, equity swaps, exchange funds and collars without prior written approval pursuant to the pre-clearance procedures set forth in the policy.

A copy of our Insider Trading Policy can be found as Exhibit 19.1 to our Annual Report on Form 10-K for the fiscal year ended June 30, 2026.

Clawback Policy

We have adopted the Compensation Recoupment Policy, effective October 2, 2023, pursuant to the new SEC rules and NASDAQ listing requirements. which applies to all equity and/or cash incentive-based compensation, and allows the Company to recover incentive-based compensation from current or former executive officers in the event of a restatement of the Company’s financial statements in compliance with Section 10D of the Exchange Act. The clawback will apply to incentive compensation that was awarded during the three completed fiscal years immediately preceding the date the Company is required to prepare the restatement with the amount of the clawback to be calculated as the portion of incentive-based compensation received by the executive officer based on the erroneous data in the original financial statements over the incentive-based compensation that would have been received based on the restated results.

Risk Assessment

The Compensation Committee believes the various components of the total compensation package of our named executive officers, as discussed above, are appropriately balanced so as to avoid any excessive risk taking by such individuals. Factors considered by the Compensation Committee include:

•Our executive compensation program reflects an appropriate mix of compensation elements and balances annual and long-term performance objectives and cash and equity compensation.

•A significant portion of our executive compensation program is performance-based and aligns with the long-term interests of our shareholders.

•We use a combination of performance metrics that are consistent with our business objectives and correlate to long-term shareholder value.

•Our performance goals are set at levels that we believe are reasonable in light of past performance and market conditions.

•Long-term equity awards tied to the market price of our common shares represent a significant component of executive officer compensation and promote a commonality of interest between the executive officers and our shareholders in increasing shareholder value.

•The use of restricted share units which provide varying levels of compensation as the market price of the Company’s common shares fluctuates over time mitigates the potential risk that options pose in encouraging risk taking in the short term and are less likely to contribute to excessive risk taking. Furthermore, our equity awards are comprised of time-based and performance-based awards that vest, if at all, over a period of years, and that vesting element encourages the award recipients to focus on sustaining our long-term performance.

•Under the annual cash bonus program, an individual target bonus amount is established for each named executive officer at each level of potential goal attainment. Accordingly, at all levels of performance goal attainment, there are limits in place for the potential bonus payout. In addition, a maximum bonus amount is established for each executive officer such that no executive officer may earn more than a fixed percentage of his or her base salary.

•Our share ownership guidelines require our named executive officers to hold a significant level of our common shares so that each executive has personal wealth tied to the long-term success of the Company and is thereby aligned with shareholders’ interests.

•Our Chief Executive Officer is required to hold at least 50% of the shares issued to him (net of shares withheld to cover taxes) under full value awards (i.e., share awards, performance share awards, restricted share units, and performance share units) for a period of one year which further aligns his interests with shareholders’ interests, as described above in the section titled “Executive Compensation Practices – CEO Post-Vesting Holding Requirement”.

Accordingly, our overall compensation structure is not overly-weighted toward short-term incentives, and the Compensation Committee has taken what it believes are reasonable steps to protect against the potential of disproportionately large short-term incentives that might encourage excessive risk taking.

Internal Revenue Code Section 162(m)

Section 162(m) of the Internal Revenue Code generally disallows a federal income tax deduction for publicly-traded companies such as the Company for compensation paid to its named executive officers and certain other executive officers to the extent that such compensation exceeds one million dollars per officer in any one year.

While the Compensation Committee considers tax deductibility as one of many factors in determining executive compensation, it may continue to provide one or more named executive officers with the opportunity to earn incentive compensation, whether through cash incentive programs or equity incentive programs, which may be in excess of the amount deductible by reason of Section 162(m) or other provisions of the Internal Revenue Code.

Summary Compensation Table

The following table provides information regarding the compensation paid during our fiscal year ended June 30, 2026 to our principal executive officer, our principal financial officer and our two other executive officers with aggregate compensation in excess of $100,000. We refer to these individuals as our named executive officers.

(1)						The dollar value shown represents the grant date fair value of the award determined in accordance with FASB ASC Topic 718 without taking into account any estimated forfeitures related to service vesting conditions. For assumptions used in determining such grant date fair value, see Note 10 to the consolidated financial statements contained in our Annual Report on Form 10-K for the fiscal year ended June 30, 2026, as filed with the SEC on August 27, 2026. For time-based restricted share unit awards, the grant date fair value was determined using the closing share price of the Company’s common shares on the date of grant. For the performance-based restricted share unit awards, the grant-date fair value is calculated based on the probable outcome of the attainment of the respective pre-established performance objectives as of the grant date at target attainment (which is the maximum level of attainment).

(2)						No bonuses were payable for the 2024-2026 calendar years.

(1)						Each named executive officer was granted a performance- based restricted share units award under our 2018 Omnibus Incentive Plan covering the target number of shares specified in the table which represents the maximum number of shares that may be earned under the award. The number of shares to be ultimately earned under award is determined based on the level of predetermined financial goals during the performance period from January 1, 2026 to December 31, 2026. The units earned based on performance vest in four equal annual installments over the four-year period of service measured from March 16, 2026, subject to accelerated vesting in the event of a change in control of our company as further described in “Agreements Regarding Employment, Change in Control and Termination of Employment” section below. The minimum number of shares that can be earned under the awards assumes that threshold level has been attained.

(2)						Each named executive officer was granted a time-based restricted share units award under our 2018 Omnibus Incentive Plan. The units vest in four equal annual installments over a four-year period of service measured from March 16, 2026, subject to accelerated vesting in the event of a change in control of our company as further described in “Agreements Regarding Employment, Change in Control and Termination of Employment” section below.







(3)						Reflects the grant-date fair value of the restricted share unit awards as calculated in accordance with FASB ASC Topic 718 without taking into account any estimated forfeitures related to service vesting conditions. For assumptions used in determining such grant date fair value, see Note 10 to the consolidated financial statements contained in our Annual Report on Form 10-K for the fiscal year ended June 30, 2026, as filed with the Securities Exchange Commission on August 27, 2026. For the performance-based restricted share unit awards, the grant-date fair value is calculated based on the probable outcome of the attainment of the pre-established performance objectives as of the grant date at target attainment (which is the maximum level of attainment).

Agreements Regarding Employment, Change in Control and Termination of Employment

Employment Agreement and Retention Agreements

We entered into an employment agreement with Mr. Stephen Chang effective March 1, 2023 in connection with his appointment as our Chief Executive Officer. We had previously entered into an employment agreement with Dr. Mike F. Chang which was amended effective March 1, 2023 to reflect his role as the Executive Chairman. This employment agreement was further amended, effective March 3, 2025, in connection with his transition to Executive Vice President of Strategic Initiatives. We have also entered into retention agreements with each of Messrs. Liang, Li and Xue. Mr. Liang’s agreement superseded his prior retention agreement.

Pursuant to his employment agreement, Mr. Stephen Chang is entitled to a base salary of $490,000 per year (effective

March 1, 2023). His base salary is subject to annual review and may be adjusted by our Compensation Committee at its discretion. The Compensation Committee increased his salary to $519,841 effective July 1, 2026. In addition, Mr. Stephen Chang is eligible to receive a cash bonus in an amount determined by our Compensation Committee based on attainment of specified performance goals. He is also entitled to participate in the benefit plans generally available to our employees, such as group health care coverage and 401(k) plan participation.

Under the terms of his employment agreement, should Mr. Stephen Chang’s employment be involuntarily terminated by us without cause or by him for good reason at any time other than during the 12 months following a change in control of the Company, he will be entitled to receive (i) continued base salary for a period of 12 months and (ii) continued health care coverage for himself and his eligible dependents for a period of 12 months. Should his employment be involuntarily terminated by us without cause or by him for good reason within 12 months following a change in control of the Company, he will be entitled to receive (i) continued base salary for a period of 24 months, (ii) 200% of his target bonus for the year of termination payable in 24 installments at the same time as continued base salary payments, (iii) continued health care coverage for himself and his eligible dependents for a period of 24 months, and (iv) accelerated vesting of his then unvested equity awards (other than the market performance share unit awards).

Pursuant to the retention agreements, each of Messrs. Liang, Li and Xue is entitled to receive severance payments and benefits upon an involuntary termination of his employment. Should the named executive officer's employment be involuntarily terminated by us without cause or by him for good reason at any time other than during the 12 months following a change in control of the Company, he will be entitled to receive (i) continued base salary for a period of 6 months, and (ii) continued health care coverage for himself and his eligible dependents for a period of 6 months. In the event that such involuntary termination occurs within 12 months following a change in control of the Company, then the named executive officer will be entitled to receive (i) continued base salary for a period of 6 months, (ii) 50% of his target bonus for the year of termination payable in 6 installments at the same time as continued base salary payments, (iii) continued health care coverage for himself and his eligible dependents for a period of 6 months and (iv), full vesting acceleration of his outstanding equity awards (other than the market performance share unit awards).

If any payment or benefit in connection with a change in control or the subsequent termination of a named executive officer's employment would be subject to an excise tax under Section 280G of the Internal Revenue Code, then such payment of benefit will be reduced to the extent necessary to maximize his net after tax benefits.

As a condition to the severance payments and benefits, each named executive officer must deliver a general release of all claims against us and our affiliates. In addition, severance benefits are conditioned on the executive's continued compliance with non-compete and non-solicitation restrictive covenants for the severance period.

For purposes of the employment agreements and the retention agreements with our named executive officers, the following definitions will be in effect:

A change in control will be deemed to occur upon (i) a merger, consolidation or other reorganization approved by our shareholders, unless our shareholders continue to own more than fifty percent (50%) of the total combined voting power of the voting securities of the successor corporation; (ii) a shareholder-approved sale of all or substantially all of our assets; or (iii) the acquisition by any person or related group of persons of more than fifty percent (50%) of the total combined voting power of our outstanding securities; or (iv) a change in a majority of the Board over a 12-month period, unless the Board members have been approved by the incumbent Board.

A resignation for good reason will be deemed to occur should the individual resign from his employment with us for any of the following reasons during the applicable change in control protection period: (i) a material diminution in his authorities, duties or responsibilities; (ii) a material reduction in his base compensation; (iii) a material relocation of his existing work site; or (iv) any material breach by us of any provision of any agreement we have with such individual.

An individual's employment will be deemed to have been terminated for cause if such termination occurs by reason of: (i) the commission of any act of fraud, embezzlement or dishonesty by the individual or his conviction of a felony, (ii) any unauthorized use or disclosure by the individual of confidential information or trade secrets of the Company (or any parent or subsidiary), (iii) any other misconduct by the individual adversely affecting the business or affairs of the Company in a material manner, (iv) the individual’s failure to cure any breach of his obligations under certain agreements with the Company, or (v) the individual’s breach of any of his fiduciary duties as an officer or director of the Company.

Potential Payments upon Termination or Change in Control

Below is a description of the potential payments and benefits that would be provided to our named executive officers upon termination of their employment or a change in control under their employment or retention agreements and equity award agreements.

Restricted Share Unit Acceleration on Change in Control

The time-based restricted share unit awards granted to our named executive officers under our various equity plans will each vest on an accelerated basis as to all the shares in the event those awards are not assumed, replaced or otherwise continued in connection with certain changes in control or ownership of the Company. In the event of such changes, the performance-based restricted share unit awards will convert into (i) the right to receive 50% of the number of target shares subject to the award in the event such change occurs prior to completion of the performance period and (ii) the right to receive the number of shares based on actual performance if such change occurs after completion of the performance period, subject in each case to continued service requirements; such shares will vest on an accelerated basis in the event those awards are not assumed, replaced or otherwise continued in connection with the change in control or ownership. Under the market performance restricted share unit awards (with respect to which the performance period has already been completed), the performance qualified shares will be paid out at the time of the change in control unless those awards are assumed, replaced or otherwise continued by the acquiring entity. Any awards that are assumed, replaced or otherwise continued will continue to vest over the service period for the award subject to accelerated vesting upon the executive officer’s involuntary termination within 12 months following the change in control (in accordance with the employment and retention agreements) and with respect to the market performance restricted share unit awards, upon the executive officer’s termination by the Company other than for cause within 18 months following the change in control.

The table below sets forth the intrinsic value of the restricted share unit awards held by each named executive officer that would accelerate (in accordance with the terms of the equity plans or agreements governing those awards) upon a change in control or ownership in which those awards were not assumed or replaced had such change in control or ownership occurred on June 30, 2026:


Named Executive Officer	Intrinsic Value of Accelerated RSUs (1)
Stephen C. Chang	$	15,648,481
Yifan Liang	$	5,827,506

Wenjun Li	$	2,603,150
Bing Xue	$	4,496,350


(1)						Such value is determined by multiplying (A) the fair market value per common share on June 30, 2026 ($47.33 per share) by (B) the number of unvested shares that would vest on an accelerated basis under such awards.

Potential Payments upon Termination of Employment

Termination in Absence of Change in Control. The following table provides the total dollar value of the compensation that each named executive officer would have been entitled to receive had his employment been terminated without cause or he had resigned for good reason on June 30, 2026 in the absence of a change in control of the Company:


Named Executive Officer	Cash Severance		Health Benefits (1)		Total
Stephen C. Chang	$	504,700	$	35,282	$	539,982
Yifan Liang	$	190,550	$	17,871	$	208,421

Wenjun Li	$	176,130	$	22,147	$	198,277
Bing Xue	$	180,250	$	25,132	$	205,382


(1)						Represents the aggregate full premium payments that would be required to be paid on behalf of each named executive officer to provide continued health insurance coverage under COBRA (based on the executive's health insurance coverage as of June 30, 2026) for the maximum period available to the executive.

Termination in Connection with Change in Control. The following table provides the total dollar value of the compensation that each named executive officer would be entitled to receive if his employment was terminated without cause or he resigned for good reason on June 30, 2026 in connection with a change in control of the Company in which the outstanding equity awards are assumed, replaced or otherwise continued.


Named Executive Officer	Cash Severance (1)		Health Benefits (2)		Bonus (3)		Accelerated Vesting of Restricted Share units (4)(5)		Total
Stephen C. Chang	$	1,009,400	$	70,564	$	1,009,400	$	15,648,481	$	17,737,845

Yifan Liang	$	190,550	$	17,871	$	133,385	$	5,827,506	$	6,169,312



Wenjun Li	$	176,130	$	22,147	$	123,291	$	2,603,150	$	2,924,718

(1)						Represents the continued base salary payable for the specified period.

(2)						Represents the aggregate full premium payments that would be required to be paid on behalf of each named executive officer to provide continued health insurance coverage under COBRA (based on the executive's health insurance coverage as of June 30, 2026) for the maximum period available to the executive.



(3)						For Stephen C. Chang, represents 200% of the named executive officer’s target bonus for fiscal year 2026 (which target bonus is calculated as 100% of Stephen C. Chang’s base salary as of June 30, 2026); for the other named executive officers, represents 50% of the named executive officer’s target bonus for fiscal year 2026 (which target bonus is calculated as 70% of the executive’s base salary as of June 30, 2026).

(4)						Represents the value of restricted share units that would vest on an accelerated basis in connection with such termination. The value is determined by multiplying (A) the number of unvested units that would vest on an accelerated basis under the award by (B) the fair market value per common share on June 30, 2026 ($47.33 per share).

(5)						Includes the value of market performance share unit awards that accelerate only on a termination without cause.

CEO Pay Ratio

As required by Section 953(b) of the Dodd-Frank Act and Item 402(u) of Regulation S-K, we are providing the following information about the relationship of the median of the annual total compensation of our employees and the annual total compensation of our Chief Executive Officer.

For fiscal year 2026, the total annual compensation of our Chief Executive Officer was $3,401,014, and the total annual compensation for our median employee, located in China, was $20,821, resulting in a pay ratio of 163:1. The median employee’s 2026 total compensation was calculated in the same manner as would be required by Item 402(c)(2)(x) of Regulation S-K if the employee was a named executive officer in 2026, and the 2026 annual total compensation of our Chief Executive Officer represents the amount reported in the “Total” column of the Summary Compensation Table.

To help understand this disclosure, it is important to provide context to our operations and employee population. Of our total employee population of 2,519 employees based on 2026 data, only 817 employees (i.e. approximately 32%) are located in the U.S. and 68% are located outside the U.S., and 58% of our employees work in China. The majority of the positions in China are hourly direct labor. The median employee is senior accounting clerk at our manufacturing facilities in China who in fiscal year 2026 earned the U.S. dollar equivalent of $20,821, which is competitive pay for this position in China but significantly lower than the salary paid for a similar position in the U.S. Our ratio is thus impacted by our strategy to source our core manufacturing in China.

In light of the significant percentage of employees located outside of the U.S., and in the interest of providing additional disclosures that investors and shareholders may find meaningful, we also conducted two supplemental pay ratio calculations based on the same methodology and assumptions used in calculating the pay ratio for the median employee based on the entire employee population, as described below. For the first one, we compared Chief Executive Officer pay with compensation of all our employees other than hourly direct labor employees in China (this alternate group was comprised of 1,709 employees worldwide, including China) which resulted in a median employee with total U.S. dollar equivalent compensation of $62,370 and a pay ratio of 55:1. For the second calculation, we included only our U.S. employees which resulted in a median employee with compensation equal to $109,475 and a pay ratio of 31:1.

We used the following methodology and assumptions to identify the median employee and calculate the annual total compensation of the median-paid employee for all three ratios presented herein:

•We selected June 30, 2026 as the date on which to determine our median employee. As of that date, we had approximately 2,519 employees, of which approximately 1,702 were located outside the U.S.

•SEC regulations allow employers to identify the median based on a “consistently applied compensation measure” (CACM). We used (A) annualized base salary plus (B) overtime pay plus (C) bonus or other incentive compensation for fiscal year ended June 30, 2026 as our CACM because these elements are consistently available across all countries where we have employees. Base pay for hourly employees was calculated based on a reasonable estimate of hours worked (including overtime) in fiscal 2026, and on salary levels for all remaining employees.

•We ranked this compensation measure for our employees from lowest to highest. This calculation was performed for all employees except our Chief Executive Officer, whether employed on full-time or part-time basis. We converted amounts paid in foreign currencies to the U.S. dollar based on the exchange rates on June 30, 2026.

•As indicated above, we performed two additional calculations: one involved excluding our direct labor employees in China and the second one involved including only our U.S. employees.

The pay ratio reported above is a reasonable estimate calculated in a manner consistent with SEC rules based on our internal records and the methodology described above. Because the SEC rules for identifying the median compensated employee and calculating pay ratio allow companies to adopt a variety of methodologies, apply certain exclusions, and make reasonable estimates and assumptions that reflect their employee populations and compensation practices, our pay ratio may not be comparable to the pay ratios reported by other companies.

COMPENSATION COMMITTEE REPORT

The information contained in the Compensation Committee Report shall not be deemed to be “soliciting material” or to be “filed” with the SEC, nor shall such information be incorporated by reference into any future filing under the Securities Act of 1933, as amended (the “Securities Act”), except to the extent that the company specifically incorporates the information by reference in such filing.

The Compensation Committee has reviewed and discussed the Compensation Discussion and Analysis required by Item 402(b) of Regulation S-K with management. Based on such review and discussions, the Compensation Committee has recommended to our Board that the Compensation Discussion and Analysis be included in this Proxy Statement.

PAY VERSUS PERFORMANCE

In accordance with Section 953(a) of the Dodd-Frank Act and Item 402(v) of Regulation S-K, we are providing the following information about the relationship between executive compensation actually paid (“CAP”) as calculated under applicable SEC rules to each of our chief executive officers, also referred to as our principal executive officers (the “PEOs”) and our other named executive officers (the “Non-PEO NEOs”) and certain measures of company performance for the fiscal years listed below.

In determining the CAP to our PEOs and the CAP to our Non-PEO NEOs, we are required to make various adjustments to the total compensation amounts that have been reported in the Summary Compensation Table (“SCT”) for each such individual, as the SEC’s valuation methods for this section differ from those required in the SCT. Information regarding the methodology for calculating CAP to our PEO(s) and the CAP to our Non-PEO NEOs, including details regarding the amounts that were deducted from, and added to, the SCT totals to arrive at the values presented for CAP, are provided in the footnotes to the table. A narrative discussion of the relationship between CAP and the financial performance measures is also presented below. Note that for Non-PEO NEOs, compensation is reported as an average.

For information on our compensation philosophy, please see “Compensation Discussion and Analysis.” The compensation setting process for our named executive officers as described therein is done independently from the disclosure requirements shown in this section. Accordingly, the Compensation Committee did not consider the pay versus performance disclosure below in making its pay decisions for any of the years shown.

The metric in this column, the Company’s revenue in the Company’s audited financial statements, in our assessment, represents the most important Company financial performance measure (that is not otherwise disclosed in this table) used to link Compensation Actually Paid to the Company’s performance for our PEOs and Non-PEO NEOs for all years presented. We believe revenue is the most important financial performance measure because as a technology company, our ability to grow and expand our market is a critical element of our success, and our investors and shareholders evaluate our success by the amount of sales we make to customers. Other key financial performance measures linked to executive compensation are described in the section below titled “Financial Performance Measures”.

Relationship Between Compensation Actually Paid and Performance

“Compensation Actually Paid”, as calculated in accordance with Item 402(v) of Regulation S-K, reflects adjusted values to unvested and vested equity awards during the years presented based on year-end stock prices, various accounting valuation assumptions, and projected performance modifiers, but does not reflect actual amounts paid out for those awards. “Compensation Actually Paid” generally fluctuates due to stock price achievement and varying levels of projected and actual achievement of performance goals.

The following graphs show the relationship between “Compensation Actually Paid” to our PEOs and other Non-PEO NEOs in the years presented and (1) TSR of both our common shares and the Philadelphia Semiconductor Index, (2) our net income, and (3) our company selected financial measure.

Financial Performance Measures

As described in further detail in this Compensation Discussion and Analysis, our executive compensation program incorporates various financial performance measures. Such measures are used in both our long-term and short-term incentive awards and are selected with the objective of incentivizing our PEOs and Non-PEO NEOs to increase the long-term value of our company for shareholders. The most important financial performance measures used in fiscal year 2026 to link Compensation Actually Paid to our PEO and Non-PEO NEOs to our financial performance are as follows (listed in no particular order of importance):


Revenue

Gross Margin
Non-GAAP Gross Margin

SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT

The following table sets forth information with respect to the beneficial ownership of our common shares, as of September 17, 2026, by:

•each of our directors and executive officers named in the Summary Compensation Table of the Executive Compensation section of this Proxy Statement;

•all current directors, director nominees and named executive officers as a group: and

•each person known to us to own beneficially more than 5% of our common shares.

The calculations in the shareholder table below are based on 30,305,071 common shares outstanding as of September 17, 2026. Beneficial ownership is determined in accordance with the rules of the SEC. All common shares issuable upon exercise of outstanding options and vesting of restricted share units within 60 days following September 17, 2026 are deemed to be beneficially owned by the shareholder holding such options or units for the purpose of computing the number of shares beneficially owned by such shareholder. They are not, however, deemed to be outstanding for the purpose of computing the percentage ownership of any other shareholder.

Except as described in the footnotes below, we believe each shareholder has sole voting and investment power with respect to the common shares indicated in the table as beneficially owned.

Policies and Procedures

The Audit Committee of the Board is responsible for establishing policies and procedures for reviewing and approving all related party transactions as defined under SEC rules and regulations. The Audit Committee also adopted the Related Party Transactions Policy (the “Policy”) that sets forth the substantive and procedural requirements for approving related party transactions. The following provides a summary of the Policy.

The Policy provides that the Audit Committee is entrusted with the responsibility and authority to review “interested transaction,” the definition of which is materially consistent with the definition of “related party transactions” under SEC rules (the “Interested Transaction”). The Audit Committee shall review the material facts of all Interested Transactions that require the Audit Committee’s approval and either approve or disapprove of the entry into the Interested Transaction.

In determining whether to approve or ratify an Interested Transaction, the Audit Committee will take into account all factors that it deems appropriate, including whether the Interested Transaction is negotiated or consummated on terms no less favorable to the Company than terms generally available or offered to an unaffiliated third-party under the same or similar circumstances and the extent of the related party’s interest in the transaction. The Policy also provides that no director shall participate in any discussion or approval of an Interested Transaction for which he or she is a related party, except that the director shall provide all material information concerning the Interested Transaction to the Audit Committee.

The Policy provides a list of Interested Transactions that are deemed to be pre-approved by the Audit Committee such that no separate approval will be required by the Audit Committee, including:

•Employment of executive officer if the compensation is approved by the Compensation Committee;

•Compensation of directors that is consistent with the Company’s director compensation policies and required to be disclosed in the proxy statement;

•Transaction with another company where the related party’s relationship is an employee (other than executive officer or director) or a shareholder, if the value of the transaction does not exceed the greater of $1,000,000 or 2% of such company’s annual revenue; and

•Certain charitable contributions if the aggregate amount does not exceed $1,000,000 or 2% of the organization’s annual revenue.

REPORT OF THE AUDIT COMMITTEE

The following is the report of the Audit Committee with respect to our audited financial statements for the fiscal year ended June 30, 2026. The information contained in this report shall not be deemed to be “soliciting material” or to be “filed” with the SEC, nor shall such information be incorporated by reference into any future filing under the Securities Act, except to the extent that the company specifically incorporates the information by reference in such filing.

The Audit Committee is comprised of three independent directors: Claudia Chen, Chair of the Audit Committee, Michael L. Pfeiffer, and Michael J. Salameh, and following the Annual Meeting is expected to consist of Claudia Chen, Michael J. Salameh, and So-Yeon Jeong. The purpose of the Audit Committee is to assist our Board in its general oversight of our financial reporting, internal controls and audit functions. The Audit Committee is directly responsible for the appointment, retention, evaluation, compensation, oversight and termination of our independent registered public accounting firm.

The Audit Committee reviews the results and scope of audit and other services provided by the independent auditors and reviews the accounting principles and auditing practices and procedures to be used in our financial reporting process, including its systems of internal control, and in the preparation of consolidated financial statements in accordance with generally accepted accounting principles. Our independent registered public accounting firm for the last fiscal year, Deloitte & Touche LLP (“Deloitte”), was responsible for performing an independent audit of those financial statements. As more fully explained in the Audit Committee’s charter, the Audit Committee’s responsibility is to provide oversight of and to review those processes. The Audit Committee does not conduct auditing or accounting reviews or perform procedures and the Audit Committee relies on information and representations provided by management and the independent auditors. The Audit Committee has relied on management’s representation that the financial statements have been prepared with integrity and objectivity and in conformity with accounting principles generally accepted in the United States and on the representations of the independent registered public accounting firm included in their report on our financial statements.

The Audit Committee has reviewed and discussed the audited financial statements with our management. Management is responsible for maintaining adequate internal control over financial reporting and for assessing the effectiveness of internal control over financial reporting. The Audit Committee was kept apprised of the progress of management’s assessment of our internal control over financial reporting and provided oversight to management during the process. In connection with this oversight, the Audit Committee received periodic updates provided by management at meetings throughout the year. At the conclusion of the process, management provided the Audit Committee with a report on the effectiveness of our internal control over financial reporting. The Audit Committee reviewed this report of management and Item 9A, “Control and Procedures,” contained in our Annual Report on Form 10-K for the fiscal year ended June 30, 2026 filed with the SEC, as well as Deloitte’s reports of independent registered public accounting firm (included in our Annual Report on Form 10-K) relating to its audits of the consolidated financial statements and of internal control over financial reporting. The Audit Committee has reviewed with management and Deloitte (a) matters related to the conduct of the audit of the consolidated financial statements by the independent registered public accounting firm and its audit of internal control over financial reporting pursuant to Section 404 of the Sarbanes-Oxley Act of 2002, as amended and (b) the additional analyses undertaken and procedures performed by us to support certifications by our Chief Executive Officer and Chief Financial Officer that are required by the SEC and the Sarbanes-Oxley Act of 2002 to accompany our periodic filings with the SEC.

In addition, the Audit Committee has reviewed and discussed the audited financial statements with Deloitte, including such items set forth in Public Company Accounting Oversight Board (PCAOB) Auditing Standard No. 16, Communications with Audit Committees or any successor standard. The Audit Committee has received from Deloitte the written disclosures and the letter required by the PCAOB, and the Audit Committee has discussed with Deloitte the independence of the independent registered public accounting firm.

After review of all discussions and all written correspondence described above, as well as such other matters deemed relevant and appropriate by the Audit Committee, the Audit Committee recommended to our Board that the audited financial statements for the last fiscal year be included in our Annual Report on Form 10-K for the fiscal year ended June 30, 2026.

PROPOSAL NO. 5

Ratification of Appointment of Independent Registered Public Accounting Firm

The Audit Committee has selected Deloitte & Touche LLP (“Deloitte”) as our independent registered public accounting firm to conduct the audit for the fiscal year ending June 30, 2027. Shareholders are asked to approve and ratify the appointment of Deloitte as our independent registered public accounting firm, and to authorize our Board, acting through our Audit Committee, to determine the remuneration of such accounting firm. On November 19, 2024, we announced that our Audit Committee had approved the engagement of Deloitte as our independent registered public accounting firm, replacing Baker Tilly US, LLP (“Baker Tilly”), effective immediately, our prior independent registered public accounting firm. Representatives of Deloitte are expected to be present at the Annual Meeting to respond to any questions from shareholders.

Change of Independent Public Accountants

On November 19, 2024, the Audit Committee of the Board approved the dismissal of Baker Tilly as the Company’s independent registered public accounting firm, effective immediately.

The audit reports of Baker Tilly on the Company’s consolidated financial statements as of and for the fiscal years ended June 30, 2024 and 2023 did not contain an adverse opinion or a disclaimer of opinion, and were not qualified or modified as to uncertainty, audit scope or accounting principle. The audit report of Baker Tilly on the effectiveness of internal control over financial reporting as of June 30, 2023 indicated that the Company did not maintain effective internal control over financial reporting as of June 30, 2023, because of the effect of the material weakness, described below.

During fiscal years ended June 30, 2024 and 2023, and the subsequent interim period through November 19, 2024, there were no disagreements as described under Item 304(a)(1)(iv) of Regulation S-K with Baker Tilly on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure, which disagreements, if not resolved to the satisfaction of Baker Tilly, would have caused Baker Tilly to make reference to the subject matter thereof in connection with its reports on the financial statements of the Company for such years. In addition, during the fiscal years ended June 30, 2024 and 2023, and the subsequent interim period through November 19, 2024, there were no reportable events as described under Item 304(a)(1)(v) of Regulation S-K, except for the material weakness in the Company’s internal control over financial reporting, as reported in Item 9A of Part II of the Company’s Annual Report on Form 10-K for the year ended June 30, 2023, filed with the SEC on August 29, 2023, related to (i) ineffective design and maintenance of effective information technology general controls in the areas of user access, and segregation of duties for one of the information technology systems that supports the Company’s financial reporting over inventory (work in process and finished goods) in costing; and (ii) failure to identify and test controls to ensure the reliability of the costing of inventory (work in process and finished goods). The Company remediated the material weakness as of June 30, 2024, as reported in Item 9A of Part II of the Company’s Annual Report on Form 10-K for the year ended June 30, 2024, filed with the SEC on August 23, 2024. The Company and the Audit Committee have discussed the reportable event described above with Baker Tilly and have authorized Baker Tilly to respond fully to the inquiries of the successor independent registered public accounting firm concerning this material weakness.

The Company has provided Baker Tilly with a copy of the disclosure contained in its Current Report on Form 8-K filed on November 25, 2024 (the “Original Form 8-K”), as amended, and requested that Baker Tilly furnish it with a letter addressed to the SEC stating whether or not it agrees with the statements contained in the Original Form 8-K. A copy of Baker Tilly’s letter, dated November 25, 2024, was filed as Exhibit 16.1 to the Original Form 8-K.

Effective as of November 19, 2024, the Audit Committee of the Board approved the appointment of Deloitte to serve as the Company’s independent registered public accounting firm for the fiscal year ended June 30, 2025, subject to Deloitte’s completion of its standard client acceptance procedures.

During the two fiscal years ended June 30, 2024 and 2023, and the subsequent interim period through November 19, 2024, neither the Company nor anyone acting on its behalf has consulted with Deloitte with respect to (i) the application of accounting principles to a specified transaction, either completed or proposed, or the type of audit opinion that might be rendered on the Company’s financial statements, and neither a written report nor oral advice was provided that Deloitte concluded was an important factor considered by us in reaching a decision as to any accounting, auditing or financial reporting issue; (ii) any matter that was the subject of a disagreement as defined in Item 304(a)(1)(iv) of Regulation S-K of Securities and Exchange Act of 1934, as amended, and the related instructions thereof; or (iii) a reportable event as described in Item 304(a)(1)(v) of Regulation S-K.

Recommendation of the Board

The Board recommends that shareholders vote FOR the approval and ratification of the appointment of Deloitte as our independent registered public accounting firm, and the authorization for our Board, acting through our Audit Committee, to determine the remuneration of the accounting firm, for fiscal year ending June 30, 2027.

FUTURE SHAREHOLDER PROPOSALS AND NOMINATIONS FOR

THE 2027 ANNUAL GENERAL MEETING

Under Rule 14a-8 of the Exchange Act, for a shareholder proposal to be considered for inclusion in the proxy statement for the 2027 annual general meeting of shareholders, we must have received the written proposal by such shareholder no later than June 2, 2027. Such proposals must comply with the other provisions of Rule 14a-8 and additional applicable SEC rules regarding the inclusion of shareholder proposals in the proxy materials. In addition, under Rule 14a-4 of the Exchange Act, the proxy solicited by the Board of Directors for the Annual Meeting in 2027 will confer discretionary authority to vote on any shareholder proposal presented at that meeting, if we do not receive notice of such proposal prior to August 16, 2027.

If you wish to bring a matter before an annual general meeting and the proposal is submitted outside the process of Rule 14a-8, you may use the procedures set forth in the Bye-laws to make a shareholder proposal, including director nominations, not intended to be included in our proxy statement under Rule 14a-8 so long as such proposal complies with our Bye-laws. Shareholder nominations and proposals may be voted on at an annual general meeting of shareholders only if such nominations and proposals are submitted to us pursuant to written notice timely and accompanied by certain information. To be timely, a shareholder’s written notice must be received by us not less than 60 nor more than 180 days to the date set for the annual general meeting of shareholders (or if no such date is set, the date that is not less than 60 nor more than 180 days prior to the anniversary of the previous year’s annual general meeting of shareholders). The notice must contain the information specified in Sections 59 and 60 of our Bye-laws with respect to the person to be nominated as director and include all material information on the proposal, statement or resolution to be put to the meeting, together with details of shareholder submitting the proposal, statement or resolution and such other information as may from time to time be specified by our Board. Under Section 60(4) of Bye-laws, the advance notice must include, but are not limited to, the following information:

•the meeting at which the person nominated is proposed for election as a director;

•information relating to direct and indirect beneficial ownership of shares, including ownership of derivative instrument, by the shareholders and their affiliates and associates acting in concert with the shareholders;

•any agreement, arrangement, relationship by the shareholders that may increase or decrease the voting power of the shareholders;

•a description of direct and indirect compensation, material monetary agreement and other related party transactions between the shareholders and their affiliates and associates acting in concert therewith and the nominees;

•a signed questionnaire by the nominee regarding his or her background, qualifications and other representations;

•a written consent of the nominee to his being named in a proxy statement as a nominee and to serve as a director, if elected; and

•any other information relating to such shareholder that would be required to be disclosed in the proxy statement under the Exchange Act;

In addition, the shareholder will be required to update and supplement, if necessary, the advance notice so the information is true and correct as of date of the annual meeting and as of the date that is 10 business days from the meeting. Our Board will review proposals from eligible shareholders which it receives by that date and will determine whether any such proposal has been received in accordance with the Bye-laws and whether any such proposal will be acted upon at the annual general meeting of shareholders. All shareholder proposals and shareholder nominations should be mailed to Alpha and Omega Semiconductor Limited, Board of Directors, c/o Investor Relations, Alpha and Omega Semiconductor, Inc. 475 Oakmead Parkway, Sunnyvale, CA 94085.

Moreover, Section 79 of the Companies Act 1981 of Bermuda, as amended, provides that shareholders representing either (i) 5% or greater of the total voting rights of the shares eligible to vote at a general meeting of shareholders, or (ii) not less than 100 shareholders may propose any resolution which may properly be moved at the next annual general meeting of shareholders. Upon timely receipt of notice, we shall, at the expense of such shareholder(s), give our other shareholders entitled to receive notice of the next annual general meeting of shareholders notice of such proposed resolution. To be timely, the proposal requiring notice of a resolution must be deposited at our registered office at least six weeks before the next annual general meeting of shareholders. Shareholders satisfying the criteria of Section 79 may also require us to circulate a statement

in respect of any matter to come before an annual general meeting of shareholders by notice deposited at our registered office not less than one week prior to the annual general meeting of shareholders.

OTHER MATTERS

The Board knows of no other business to be acted upon at the Annual Meeting. However, if any other matter shall properly come before the Annual Meeting, the proxy holder named in the proxy accompanying this statement will have discretionary authority to vote all proxies in accordance with his best judgment.

ALPHA & OMEGA SEMICONDUCTOR LIMITED

2018 OMNIBUS INCENTIVE PLAN

(As amended and restated effective November 17, 2026)

ARTICLE 1

GENERAL PROVISIONS

1.1 PURPOSE OF THE PLAN

This 2018 Omnibus Incentive Plan (the “Plan”) is intended to promote the interests of Alpha and Omega Semiconductor Limited, a company incorporated and existing under the laws of the Islands of Bermuda, by providing eligible persons in the Company’s employ or service with the opportunity to acquire a proprietary interest, or otherwise increase their proprietary interest, in the Company as an incentive for them to continue in such employ or service.

The Plan serves as the successor to the Company’s 2009 Share Option/Share Issuance Plan (the “Predecessor Plan”), and no further awards shall be made under the Predecessor Plan on or after the Plan Effective Date. All awards outstanding under the Predecessor Plan on the Plan Effective Date shall remain outstanding under the Predecessor Plan and shall continue to be governed solely by the terms of the documents evidencing such award, and no provision of the Plan shall be deemed to affect or otherwise modify the rights or obligations of the holders of such awards.

Capitalized terms shall have the meanings assigned to such terms in the attached Appendix.

1.2 TYPES OF AWARDS

Awards may be made under the Plan in the form of (i) options, (ii) share appreciation rights, (iii) share awards, (iv) restricted share units, (v) dividend equivalent rights and (vi) other share-based awards.

1.3 ADMINISTRATION OF THE PLAN

(a) The Compensation Committee shall have sole and exclusive authority to administer the Plan with respect to Section 16 Insiders. Administration of the Plan with respect to all other persons eligible to participate in the Plan may, at the Board’s discretion, be vested in the Compensation Committee or a Secondary Board Committee, or the Board may retain the power to administer those programs with respect to such persons. To the extent permitted by law, the Board or the Compensation Committee may delegate any or all of its authority to administer the Plan with respect to one or more classes of eligible persons (other than Section 16 Insiders) to one or more officers of the Company.

(b) Members of the Compensation Committee or any Secondary Board Committee shall serve for such period of time as the Board may determine and may be removed by the Board at any time. The Board may also at any time terminate the functions of any Secondary Board Committee and reassume all powers and authority previously delegated to such committee.

(c) Each Plan Administrator shall, within the scope of its administrative functions under the Plan, have full authority to determine (i) which eligible persons are to receive Awards under the

A - 1

Plan, (ii) the type, size, terms and conditions of the Awards to be made to each Participant, (iii) the time or times when those Awards are to be made, (iv) the number of shares or amount of payment to be covered by each such Award, (v) the time or times when the Award is to become exercisable, (vi) the status of an option for U.S. federal tax purposes, (vii) the maximum term for which an Award is to remain outstanding, (viii) the vesting and issuance schedules applicable to the shares which are the subject of the Award, (ix) the cash consideration (if any) payable for those shares and the form (cash or Common Shares) in which the Award is to be settled, (x) with respect to performance-based Awards, the performance objectives for each such Award, the amounts payable at designated levels of attained performance, any applicable service vesting requirements, and the payout schedule for each such Award, (xi) in the event of the Participant’s death or disability, accelerate the vesting or exercisability of an Award, and (xii) in the event of a Change in Control, take any action authorized by Section 2.7 hereof.

(d) Each Plan Administrator shall, within the scope of its administrative functions under the Plan, have full power and authority (subject to the provisions of the Plan) to establish such rules and regulations as it may deem appropriate for proper administration of the Plan and to make such determinations under, and issue such interpretations of, the provisions of the Plan and any outstanding Awards thereunder as it may deem necessary or advisable. Decisions of the Plan Administrator within the scope of its administrative functions under the Plan shall be final and binding on all parties who have an interest in the Plan under its jurisdiction or any Award thereunder.

(e) Service as a Plan Administrator by the members of the Compensation Committee or the Secondary Board Committee shall constitute service as Board members, and the members of each such committee shall accordingly be entitled to full indemnification and reimbursement as Board members for their service on such committee. No member of the Compensation Committee or the Secondary Board Committee shall be liable for any act or omission made in good faith with respect to the Plan or any Award thereunder.

1.4 ELIGIBILITY

(a) The persons eligible to participate in the Plan are as follows:

(i) Employees,

(ii) Non-Employee Directors and non-employee members of the board of any Parent or Subsidiary, and

(iii) consultants and other independent advisors who provide services to the Company (or any Parent or Subsidiary).

1.5 SHARES SUBJECT TO THE PLAN

(a) The shares issuable under the Plan shall be authorized but unissued or reacquired Common Shares, including shares repurchased by the Company on the open market. The number of Common Shares reserved for issuance over the term of the Plan shall be limited to Six Million Three Hundred Seventy-Two Thousand (6,372,000) shares, subject to adjustment pursuant to Section 1.5(e) and Section 1.5(f).

(b) Subject to adjustment pursuant to Section 1.5(f), the maximum number of Common Shares that may be issued pursuant to Incentive Options granted under the Plan shall be Six Million Three Hundred Seventy-Two Thousand (6,372,000) shares.

A - 2

(c) Subject to adjustment pursuant to Section 1.5(f), the maximum number of Common Shares for which Awards that are settled in shares may be made to any person under the Plan in any fiscal year shall not exceed Eight Hundred Thousand (800,000) shares in the aggregate.

(d) The maximum aggregate number of Common Shares for which Awards may made to any Non-Employee Director under the Plan in any calendar year, taken together with any cash retainer paid to such Non-Employee Director in respect of such calendar year, shall not exceed $750,000 ($1,000,000 in the calendar year in which the Non-Employee Director is initially elected or appointed to the Board) in total value (calculating the value of any such Awards based on the grant date fair value of such Awards for financial reporting purposes and excluding, for this purpose, the value of any dividends or dividend equivalents paid on any Common Shares or Awards).

(e) Common Shares subject to outstanding Awards (including awards granted under the Predecessor Plan) shall be available for subsequent award and issuance under the Plan to the extent those Awards expire, are forfeited or cancelled or terminate for any reason prior to the issuance of the Common Shares subject to those Awards or are settled in cash. Upon the exercise of any share appreciation right under the Plan, the share reserve shall be reduced by the gross number of shares as to which such right is exercised. Should the exercise price of an option or any Withholding Taxes incurred in connection with the exercise of an option or share appreciation right under the Plan be paid with Common Shares (whether through the withholding of a portion of the otherwise issuable shares or through the tender of actual outstanding shares), then in each such case, the shares so tendered or withheld shall not be added to the Common Shares available for grant under the Plan. If Common Shares otherwise issuable under the Plan are withheld by the Company in satisfaction of the Withholding Taxes incurred in connection with the vesting or settlement of an Award (including an award granted under the Predecessor Plan) other than an option or share appreciation right, then in each such case the Common Shares so tendered or withheld shall not be added back to the Common Shares available for issuance under the Plan.

(f) Should any change be made to the Common Shares by reason of any share split, share dividend, recapitalization, combination of shares, exchange of shares, spin-off transaction, extraordinary distribution (whether in cash, securities or other property) or other change affecting the outstanding Common Shares as a class without the Company’s receipt of consideration, or should the value of outstanding Common Shares be substantially reduced as a result of a spin-off transaction or an extraordinary dividend or distribution, or should there occur any merger, consolidation, reincorporation or other reorganization, then equitable adjustments shall be made by the Plan Administrator to (i) the maximum number and/or class of securities issuable under the Plan, (ii) the maximum number and/or class of securities for which any one person may be granted Awards under the Plan in any fiscal year, (iii) the maximum number and/or class of securities that may be issued pursuant to Incentive Options, (iv) the number and/or class of securities and the exercise or base price per share in effect under each outstanding Award under the Plan (including awards under the Predecessor Plan) and the consideration (if any) payable per share, and (v) the number and/or class of securities subject to cancellation or the Company’s outstanding repurchase rights under the Plan and the repurchase price payable per share. The adjustments shall be made in such manner as the Plan Administrator deems appropriate and such adjustments shall be final, binding and conclusive. In addition, in the event of a Change in Control, the provisions of Section 2.7 shall apply.

(g) Awards may, in the sole discretion of the Plan Administrator, be granted under the Plan in assumption of, or in substitution for, outstanding awards previously granted by an entity directly or indirectly acquired by the Company or with which the Company combines (“Substitute Awards”). Substitute Awards shall not be counted against the share limit (nor shall Substitute Awards be added to the

A - 3

share limit as provided above); provided, that Substitute Awards issued in connection with the assumption of, or in substitution for, outstanding options intended to qualify as Incentive Options within the meaning of Section 422 of the Code shall be counted against the aggregate number of Common Shares available for Awards of Incentive Options under the Plan. Subject to applicable stock exchange requirements, available shares under a shareholder approved plan of an entity directly or indirectly acquired by the Company or with which the Company combines (as appropriately adjusted to reflect the acquisition or combination transaction) may be used for Awards under the Plan and shall not reduce (or be added back to) the number of Common Shares available for issuance under the Plan.

(h) Outstanding Awards granted pursuant to the Plan shall in no way affect the right of the Company to adjust, reclassify, reorganize or otherwise change its capital or business structure or to merge, consolidate, dissolve, liquidate or sell or transfer all or any part of its business or assets.

1.6 MINIMUM VESTING

Notwithstanding any other provision of the Plan to the contrary, Awards granted under the Plan that are payable in Common Shares shall vest no earlier than the first anniversary of the date on which the Award was granted, provided that the foregoing minimum vesting requirement does not apply to:

(a) Awards with respect to a maximum of 5% of the number of Common Shares available for issuance under the Plan as of the 2026 Annual Shareholders Meeting, taking into account the 2026 Share Increase (subject to shareholder approval at the 2026 Annual Shareholders Meeting), subject to adjustment under Section 1.5(f);

(b) Substitute Awards;

(d) Awards granted to Non-Employee Directors that vest on the earlier of the one-year anniversary of the date on which the Award was granted and the next annual meeting of shareholders that occurs at least 50 weeks after the prior year’s annual meeting of shareholders.

ARTICLE 2

AWARDS

2.1 OPTIONS

(a) Authority. The Plan Administrator shall have full power and authority, exercisable in its sole discretion, to grant Incentive Options and Non-Statutory Options evidenced by an Award Agreement in the form approved by the Plan Administrator; provided, however, that the terms of each such agreement shall not be inconsistent with the terms specified below. Each agreement evidencing an Incentive Option shall, in addition, be subject to the provisions of Section 2.1(f) below.

(b) Exercise Price.

(i) The exercise price per share shall be fixed by the Plan Administrator; provided, however, that such exercise price shall not be less than one hundred percent (100%) of the Fair Market Value per Common Share on the grant date.

A - 4

(ii) The exercise price shall be payable in one or more of the following forms as determined by the Plan Administrator and specified in the Award Agreement:

(A) cash or check made payable to the Company,

(B) Common Shares (whether delivered in the form of actual share certificates or through attestation of ownership) held for the requisite period (if any) necessary to avoid any resulting charge to the Company’s earnings for financial reporting purposes and valued at Fair Market Value on the Exercise Date,

(C) Common Shares otherwise issuable under the option but withheld by the Company in satisfaction of the exercise price, with such withheld shares to be valued at Fair Market Value on the Exercise Date, or

(D) to the extent the option is exercised for vested Common Shares, through a special sale and remittance procedure pursuant to which the Participant shall concurrently provide instructions to (a) a brokerage firm (reasonably satisfactory to the Company for purposes of administering such procedure in compliance with the Company’s pre-clearance/pre-notification policies) to effect the immediate sale of the purchased shares and remit to the Company, out of the sale proceeds available on the settlement date, sufficient funds to cover the aggregate exercise price payable for the purchased shares plus all applicable income and employment taxes required to be withheld by the Company by reason of such exercise and (b) the Company to deliver the certificates for the purchased shares directly to such brokerage firm on such settlement date in order to complete the sale.

Except to the extent such sale and remittance procedure is utilized, payment of the exercise price for the purchased shares must be made on the Exercise Date.

(iii) The Plan Administrator shall have the discretion (exercisable at any time) to permit the exercise price of an outstanding option to be paid in one or more of the forms specified in Section 2.1(b)(ii).

(c) Exercise and Term of Options. Each option shall be exercisable at such time or times, during such period and for such number of shares as shall be determined by the Plan Administrator and set forth in the Award Agreement evidencing the option. However, no option shall have a term in excess of ten (10) years measured from the option grant date.

(d) Effect of Termination of Service.

(i) The following provisions shall govern the exercise of any options that are outstanding at the time of the Participant’s cessation of Service or death:

(A) Any option outstanding at the time of the Participant’s cessation of Service for any reason shall remain exercisable for such period of time thereafter as shall be determined by the Plan Administrator and set forth in the documents evidencing the option, but no such option shall be exercisable after the expiration of the option term.

(B) Any option held by the Participant at the time of the Participant’s death and exercisable in whole or in part at that time may be subsequently exercised by the personal representative of the Participant’s estate or by the person or persons to whom the option is transferred pursuant to the Participant’s will or the laws of inheritance or by the Participant’s designated beneficiary or beneficiaries of that option.

A - 5

(C) Should the Participant’s Service be terminated for Misconduct or should the Participant otherwise engage in Misconduct while holding one or more outstanding options, then all of those options shall terminate immediately and cease to be outstanding.

(D) During the applicable post-Service exercise period, the option may not be exercised for more than the number of vested shares for which the option is at the time exercisable. Upon the expiration of the applicable exercise period or (if earlier) upon the expiration of the option term, the option shall terminate and cease to be outstanding for any shares for which the option has not been exercised.

(ii) The Plan Administrator shall have complete discretion, exercisable either at the time an option is granted or at any time while the option remains outstanding, to:

(A) extend the period of time for which the option is to remain exercisable following the Participant’s cessation of Service from the limited exercise period otherwise in effect for that option to such greater period of time as the Plan Administrator shall deem appropriate, but in no event beyond the expiration of the option term; and/or

(B) include an automatic extension provision whereby the specified post-Service exercise period in effect for any option shall automatically be extended by an additional period of time equal in duration to any interval within the specified post-Service exercise period during which the exercise of that option or the immediate sale of the shares acquired under such option could not be effected in compliance with applicable federal and state securities laws, but in no event shall such an extension result in the continuation of such option beyond the expiration date of the term of that option.

(e) Early Exercise. The Plan Administrator shall have the discretion to grant options which are exercisable for unvested Common Shares. Should the Participant cease Service while holding unvested shares received upon such early exercise of an option, the Company shall have the right to repurchase any or all of those unvested shares at a price per share equal to the lower of (i) the exercise price paid per share or (ii) the Fair Market Value per Common Share at the time of repurchase. The terms upon which such repurchase right shall be exercisable (including the period and procedure for exercise and the appropriate vesting schedule for the purchased shares) shall be established by the Plan Administrator and set forth in the document evidencing such repurchase right.

(f) Incentive Options. The terms specified below shall be applicable to all Incentive Options. Except as modified by the provisions of this Section 2.1(f), all the provisions of the Plan shall be applicable to Incentive Options. Options which are specifically designated as Non-Statutory Options when issued under the Plan shall not be subject to the terms of this Section 2.1(f).

(i) Eligibility. Incentive Options may only be granted to Employees.

(ii) Dollar Limitation. The aggregate Fair Market Value of the Common Shares (determined as of the respective date or dates of grant) for which one or more options granted to any Employee under the Plan (or any other option plan of the Company or any Parent or Subsidiary) may for the first time become exercisable as Incentive Options during any one calendar year shall not exceed the sum of One Hundred Thousand Dollars ($100,000).

To the extent the Employee holds two (2) or more such options which become exercisable for the first time in the same calendar year, then for purposes of the foregoing limitations on the exercisability of those options as Incentive Options, such options shall be deemed to

A - 6

become first exercisable in that calendar year on the basis of the chronological order in which they were granted, except to the extent otherwise provided under applicable law or regulation.

(iii) 10% Shareholder. If any Employee to whom an Incentive Option is granted is a 10% Shareholder, then the exercise price per share shall not be less than one hundred ten percent (110%) of the Fair Market Value per Common Share on the option grant date, and the option term shall not exceed five (5) years measured from the option grant date.

2.2 SHARE APPRECIATION RIGHTS

(a) Authority. The Plan Administrator shall have full power and authority, exercisable in its sole discretion, to grant share appreciation rights evidenced by an Award Agreement in the form approved by the Plan Administrator; provided, however, that the terms of each such agreement shall not be inconsistent with the terms specified below.

(b) Types. Two types of share appreciation rights shall be authorized for issuance under this Section 2.2: (i) tandem share appreciation rights (“Tandem Rights”) and (ii) stand-alone share appreciation rights (“Stand-alone Rights”).

(i) One or more Participants may be granted a Tandem Right, exercisable upon such terms and conditions as the Plan Administrator may establish, to elect between the exercise of the underlying option for Common Shares or the surrender of that option in exchange for a distribution from the Company in an amount equal to the excess of (i) the Fair Market Value (on the option surrender date) of the number of shares in which the Participant is at the time vested under the surrendered option (or surrendered portion thereof) over (ii) the aggregate exercise price payable for such vested shares.

(ii) Any distribution to which the Participant becomes entitled upon the exercise of a Tandem Right may be made in (i) Common Shares valued at Fair Market Value on the option surrender date, (ii) cash or (iii) a combination of cash and Common Shares, as specified in the applicable Award Agreement.

(d) Stand-Alone Rights. The following terms and conditions shall govern the grant and exercise of Stand-alone Rights:

(i) One or more Participants may be granted a Stand-alone Right not tied to any underlying option. The Stand-alone Right shall relate to a specified number of Common Shares and shall be exercisable upon such terms and conditions as the Plan Administrator may establish. In no event, however, may the Stand-alone Right have a maximum term in excess of ten (10) years measured from the grant date.

(ii) Upon exercise of the Stand-alone Right, the holder shall be entitled to receive a distribution from the Company in an amount equal to the excess of (i) the aggregate Fair Market Value (on the exercise date) of the Common Shares underlying the exercised right over (ii) the aggregate base price in effect for those shares.

(iii) The number of Common Shares underlying each Stand-alone Right and the base price in effect for those shares shall be determined by the Plan Administrator in its sole discretion at

A - 7

the time the Stand-alone Right is granted. In no event, however, may the base price per share be less than the Fair Market Value per underlying Common Share on the grant date.

(iv) The distribution with respect to an exercised Stand-alone Right may be made in (i) Common Shares valued at Fair Market Value on the exercise date, (ii) cash or (iii) a combination of cash and Common Shares, as specified in the applicable Award agreement.

(v) The holder of a Stand-alone Right shall have no shareholder rights with respect to the shares subject to the Stand-alone Right unless and until such person shall have exercised the Stand-alone Right and become a holder of record of the Common Shares issued upon the exercise of such Stand-alone Right.

(e) Post-Service Exercise. The provisions governing the exercise of Tandem and Stand-alone Rights following the cessation of the Participant’s Service shall be substantially the same as those set forth in Section 2.1(d) for the options granted under the Plan, and the Plan Administrator’s discretionary authority under Section 2.1(d)(ii) shall also extend to any outstanding Tandem Rights and Stand-alone Appreciation Rights.

2.3 SHARE AWARDS

(a) Authority. The Plan Administrator shall have full power and authority, exercisable in its sole discretion, to grant share awards through direct and immediate issuances of Common Shares. Each share award shall be evidenced by an Award Agreement in the form approved by the Plan Administrator; provided, however, that the terms of each such agreement shall not be inconsistent with the terms specified below.

(b) Consideration.

Common Shares may be issued under a share award for any of the following items of consideration which the Plan Administrator may deem appropriate in each individual instance:

(i) cash or check made payable to the Company,

(ii) past services rendered to the Company (or any Parent or Subsidiary); or

(iii) any other valid consideration under the Companies Act 1981 of Bermuda, as amended.

(i) Share awards may, in the discretion of the Plan Administrator, vest in one or more installments over the Participant’s period of Service and/or upon the attainment of specified performance objectives.

(ii) The Plan Administrator shall also have the discretionary authority to structure one or more share awards so that the Common Shares subject to those Awards shall vest upon the achievement of pre-established performance objectives based on one or more Performance Goals and measured over the performance period specified by the Plan Administrator at the time of the grant of the Award. The elements of the vesting schedule applicable to any share award shall be determined by the Plan Administrator and incorporated into the Award Agreement.

A - 8

(iii) Should the Participant cease to remain in Service while holding one or more unvested Common Shares issued under a share award or should the performance objectives not be attained with respect to one or more such unvested Common Shares, then those shares shall be immediately surrendered to the Company for cancellation, and the Participant shall have no further shareholder rights with respect to those shares. To the extent the surrendered shares were previously issued to the Participant for consideration paid in cash or cash equivalent, the Company shall repay to the Participant the lower of (i) the cash consideration paid for the surrendered shares or (ii) the Fair Market Value of those shares at the time of cancellation.

(iv) Any new, substituted or additional securities or other property (including money paid other than as a regular cash dividend) which the Participant may have the right to receive with respect to the Participant’s unvested Common Shares by reason of any share dividend, share split, recapitalization, combination of shares, exchange of shares, spin-off transaction, extraordinary dividend or distribution or other change affecting the outstanding Common Shares as a class without the Company’s receipt of consideration shall be issued subject to (i) the same vesting requirements applicable to the Participant’s unvested Common Shares and (ii) such escrow arrangements as the Plan Administrator shall deem appropriate. Equitable adjustments to reflect each such transaction shall also be made by the Plan Administrator to the repurchase price payable per share by the Company for any unvested securities subject to its existing repurchase rights under the Plan; provided the aggregate repurchase price shall in each instance remain the same.

2.4 RESTRICTED SHARE UNITS

(a) Authority. The Plan Administrator shall have the full power and authority, exercisable in its sole discretion, to grant restricted share units evidenced by an Award Agreement in the form approved by the Plan Administrator; provided, however, that the terms of each such agreement shall not be inconsistent with the terms specified below.

(b) Terms. Each restricted share unit award shall entitle the Participant to receive the shares underlying that Award (or an amount based on the value of the shares) upon vesting or upon the expiration of a designated time period following the vesting of the Award. Payment of shares underlying a restricted share unit award may be deferred for a period specified by the Plan Administrator at the time the restricted share unit award is initially granted or (to the extent permitted by the Plan Administrator) designated by the Participant pursuant to a timely deferral election made in accordance with the requirements of Code Section 409A. Restricted share units subject to performance vesting may also be structured so that the underlying shares are convertible into Common Shares (or a payment based on the value of the shares), but the rate at which each share is to so convert shall be based on the attained level of performance for each applicable performance objective.

(i) Restricted share units may, in the discretion of the Plan Administrator, vest in one or more installments over the Participant’s period of Service or upon the attainment of specified performance objectives.

(ii) The Plan Administrator shall also have the discretionary authority to structure one or more restricted share unit awards so that the Common Shares subject to those Awards shall vest (or vest and become issuable) upon the achievement of pre-established performance objectives based on one or more Performance Goals and measured over the performance period specified by the Plan Administrator at the time of the grant of the Award.

A - 9

(iii) Outstanding restricted share units shall automatically terminate without any payment if the performance goals or Service requirements established for those Awards are not attained or satisfied.

(d) Payment. Restricted share units that vest may be settled in (i) cash, (ii) Common Shares valued at Fair Market Value on the payment date or (iii) a combination of cash and Common Shares, as determined by the Plan Administrator in its sole discretion and set forth in the Award Agreement.

2.5 DIVIDEND EQUIVALENT RIGHTS

(a) Authority. The Plan Administrator shall have full power and authority, exercisable in its sole discretion, to grant dividend equivalent rights evidenced by an Award Agreement in the form approved by the Plan Administrator; provided however, that the terms of each such agreement shall not be inconsistent with the terms specified below.

(b) Terms. The dividend equivalent rights may be granted as stand-alone awards or in tandem with other Awards made under the Plan, except dividend equivalent rights shall not be granted in connection with an option or share appreciation right. The term of each dividend equivalent right award shall be established by the Plan Administrator at the time of grant, but no such award shall have a term in excess of ten (10) years.

(c) Entitlement. Each dividend equivalent right shall represent the right to receive the economic equivalent of each dividend or distribution, whether in cash, securities or other property (other than Common Shares), which is made per issued and outstanding Common Share during the term the dividend equivalent right remains outstanding. A special account on the books of the Company shall be maintained for each Participant to whom a dividend equivalent right is granted, and that account shall be credited per dividend equivalent right with each such dividend or distribution made per issued and outstanding Common Share during the term of that dividend equivalent right remains outstanding.

(d) Timing of payment. Payment of the amounts credited to such book account shall not be made to the Participant prior to the vesting of that Award (or the portion thereof to which the dividend equivalent right award relates) and shall accordingly be subject to cancellation and forfeiture to the same extent as the underlying Award. Payment may be deferred for a period specified by the Plan Administrator at the time the dividend equivalent right award is initially granted or (to the extent permitted by the Plan Administrator) designated by the Participant pursuant to a timely deferral election made in accordance with the requirements of Code Section 409A.

(e) Form of payment. Payment of the amounts due with respect to dividend equivalent rights may be made in (i) cash, (ii) Common Shares or (iii) a combination of cash and Common Shares, as determined by the Plan Administrator in its sole discretion and set forth in the Award Agreement. If payment is to be made in the form of Common Shares, the number of Common Shares into which the cash dividend or distribution amounts are to be converted for purposes of the Participant’s book account may be based on the Fair Market Value per Common Share on the date of conversion, a prior date or an average of the Fair Market Value per Common Share over a designated period, as determined by the Plan Administrator in its sole discretion.

A - 10

2.6 OTHER SHARE-BASED AWARDS

The Plan Administrator may grant other Awards denominated in Common Shares (including performance shares or performance units) under the Plan, alone or in tandem with other Awards, in such amounts as the Plan Administrator shall from time to time in its sole discretion determine. Each Other Share-Based Award granted under the Plan shall be evidenced by an Award Agreement in the form approved by the Plan Administrator. Each Other Share-Based Award so granted shall be subject to such conditions not inconsistent with the Plan as may be reflected in the applicable Award Agreement.

2.7 EFFECT OF CHANGE IN CONTROL

(a) In the event of a Change in Control, each outstanding Award, as determined by the Plan Administrator in its sole discretion, may be (i) assumed by the successor corporation (or parent thereof), (ii) canceled and substituted with an Award granted by the successor corporation (or parent thereof), (iii) otherwise continued in full force and effect pursuant to the terms of the Change in Control transaction, or (iv) replaced with a cash retention program of the Company or any successor corporation (or parent thereof) which preserves the spread existing on the unvested Award shares subject to the Award at the time of the Change in Control (the excess of the Fair Market Value of those shares over the aggregate purchase price payable for such shares) and, subject to Section 2.7(c) below, provides for subsequent payout of that spread in accordance with the same exercise/vesting schedule applicable to those unvested Award shares.

(b) To the extent an outstanding Award is not assumed, substituted, continued or replaced in accordance with Section 2.7(a), such Award shall automatically vest in full immediately prior to the effective date of the Change in Control, unless the acceleration of such Award is subject to other limitations imposed by the Plan Administrator at the time of the grant of the Award. The Plan Administrator in its sole discretion shall have the authority to provide that to the extent any such Award, as so accelerated, remains unexercised and outstanding on the effective date of the Change in Control, such Award shall terminate and cease to be outstanding. The holder of such Award shall become entitled to receive, upon consummation of the Change in Control and subject to Section 2.7(c), a lump sum cash payment in an amount equal to the product of (i) number of Common Shares subject to such Award and (ii) the excess of (a) the Fair Market Value per Common Share on the date of the Change in Control over (b) the per share exercise price, base price or purchase price in effect for such Award. However, any such Award shall be subject to cancellation and termination, without cash payment or other consideration due the Award holder, if the Fair Market Value per Common Share on the date of such Change in Control is less than the per share exercise price, base price or purchase price in effect for such Award. Notwithstanding the foregoing, if any Award is subject to a performance-vesting condition tied to the attainment of one or more specified performance goals, and such Award is not to be so assumed, substituted, continued, or replaced, that Award shall vest based on actual performance attainment as of the date of the Change in Control or on a pro-rated basis for time elapsed in the ongoing performance period based on target level, immediately prior to the effective date of the actual Change in Control transaction, and the Common Shares underlying the portion of the Award that vests on such accelerated basis shall be issued in accordance with the applicable Award Agreement, unless such accelerated vesting is precluded by other limitations imposed in the Award Agreement.

(c) The Plan Administrator shall have the authority to provide that any escrow, holdback, earn-out or similar provisions in the definitive agreement effecting the Change in Control shall apply to any cash payment made pursuant to Section 2.7(a) or Section 2.7(b) to the same extent and in the same manner as such provisions apply to a holder of a Common Shares.

A - 11

(d) Immediately following the consummation of the Change in Control, all outstanding Awards shall terminate and cease to be outstanding, except to the extent assumed by the successor corporation (or parent thereof) or otherwise continued in full force and effect pursuant to the terms of the Change in Control transaction.

(e) In the event of any Change in Control, the Plan Administrator in its sole discretion may determine that all outstanding repurchase or cancellation rights (i) are to be assigned to the successor corporation (or parent thereof) or otherwise continued in full force and effect pursuant to the terms of the Change in Control transaction or (ii) are to be terminated and the Common Shares subject to those terminated rights are to immediately vest in full, unless such accelerated vesting is precluded by limitations imposed by the Plan Administrator at the time the right is issued.

(f) Each Award which is assumed in connection with a Change in Control or otherwise continued in effect shall be appropriately adjusted, immediately after such Change in Control, to apply to the number and class of securities into which the Common Shares subject to that Award would have been converted in consummation of such Change in Control had those shares actually been outstanding at that time. Appropriate adjustments to reflect such Change in Control shall also be made to (i) the exercise or base price or cash consideration payable per share in effect under each outstanding Award, provided the aggregate exercise or base price or cash consideration in effect for such securities shall remain the same, (ii) the maximum number and/or class of securities available for issuance over the remaining term of the Plan, (iii) the maximum number and/or class of securities for which Incentive Options may be granted under the Plan, (iv) the maximum number and/or class of securities for which any one person may be granted Awards under the Plan per calendar year and (v) the number and/or class of securities subject to the Company’s outstanding repurchase rights under the Plan and the repurchase price payable per share. To the extent the actual holders of the Company’s outstanding Common Shares receive cash consideration for their Common Shares in consummation of the Change in Control, the successor corporation may, in connection with the assumption or continuation of the outstanding Awards under the Plan and subject to the Plan Administrator’s approval, substitute, for the securities underlying those assumed Awards, one or more shares of its own common stock with a fair market value equivalent to the cash consideration paid per Common Shares in such Change in Control transaction.

(g) An Award may provide that if the Award is assumed or otherwise continued in effect in connection with a Change in Control, the shares subject to the Award will automatically vest on an accelerated basis should the Participant’s Service terminate by reason of an Involuntary Termination within a designated period following the effective date of the Change in Control.

(h) The portion of any Incentive Option accelerated in connection with a Change in Control shall remain exercisable as an Incentive Option only to the extent the applicable One Hundred Thousand Dollar ($100,000) limitation is not exceeded. To the extent such dollar limitation is exceeded, the accelerated portion of such option shall be exercisable as a Non-Statutory Option under the Federal tax laws.

2.8 REPRICING PROGRAMS

The Plan Administrator shall not have the discretionary authority, except pursuant to Section 1.5(g), to (i) implement cancellation/regrant programs pursuant to which outstanding options or share appreciation rights under the Plan are cancelled and new options or share appreciation rights are granted in replacement with a lower exercise or base price per share, (ii) cancel outstanding options or share appreciation rights under the Plan with exercise or base prices per share in excess of the then current Fair Market Value per Common Share for consideration payable in cash or in equity securities of the Company

A - 12

(except in the case of a Change in Control) or (iii) reduce the exercise or base price in effect for outstanding options or share appreciation rights under the Plan, in any case without shareholder approval.

ARTICLE 3

MISCELLANEOUS

3.1 DEFERRED COMPENSATION

(a) The Plan Administrator may, in its sole discretion, structure one or more Awards (other than options and share appreciation rights) so that the Participants may be provided with an election to defer the compensation associated with those Awards for federal income tax purposes. Any such deferral opportunity shall comply with all applicable requirements of Code Section 409A.

(b) The Plan Administrator may implement a non-employee Board member retainer fee deferral program under the Plan so as to allow the non-employee Board members the opportunity to elect, prior to the start of each calendar year, to convert the Board and Board committee retainer fees to be earned for such year into restricted share units under the Plan that will defer the issuance of the Common Shares that vest under those restricted share units until a permissible date or event under Code Section 409A. If such program is implemented, the Plan Administrator shall have the authority to establish such rules and procedures as it deems appropriate for the filing of such deferral elections and the designation of the permissible distribution events under Code Section 409A.

(c) To the extent the Company maintains one or more separate non-qualified deferred compensation arrangements which allow the participants the opportunity to make notional investments of their deferred account balances in Common Shares, the Plan Administrator may authorize the share reserve under the Plan to serve as the source of any Common Shares that become payable under those deferred compensation arrangements. In such event, the share reserve under the Plan shall be reduced on a share-for-share basis for each Common Shares issued under the Plan in settlement of the deferred compensation owed under those separate arrangements.

3.2 TRANSFERABILITY OF AWARDS

The transferability of Awards granted under the Plan shall be governed by the following provisions:

(a) Incentive Options. During the lifetime of the Participant, Incentive Options shall be exercisable only by the Participant and shall not be assignable or transferable other than by will or the laws of inheritance following the Participant’s death.

(b) Other Awards. All other Awards shall be subject to the same limitation on transfer as Incentive Options, except that the Plan Administrator may structure one or more such Awards so that the Award may be assigned in whole or in part during the Participant’s lifetime to one or more Family Members of the Participant or to a trust established exclusively for the Participant and/or such Family Members, to the extent such assignment is in connection with the Participant’s estate plan or pursuant to a domestic relations order. The assigned portion of an Award may only be exercised (if applicable) by the person or persons who acquire a proprietary interest in the Award pursuant to the assignment. The terms applicable to the assigned portion of the Award shall be the same as those in effect for the Award immediately prior to such assignment and shall be set forth in such documents issued to the assignee as the Plan Administrator may deem appropriate.

A - 13

(c) Beneficiary Designation. Notwithstanding the foregoing, a Participant may, to the extent permitted by the Plan Administrator, designate one or more persons as the beneficiary or beneficiaries of some or all of his or her outstanding Awards, and those Awards shall, in accordance with such designation and to the extent valid under applicable law, automatically be transferred to such beneficiary or beneficiaries upon the Participant’s death while holding those Awards. Such beneficiary or beneficiaries shall take the transferred Awards subject to all the terms and conditions of the applicable agreement evidencing each such transferred Award, including (without limitation) the limited time period during which the Award may be exercised (if applicable) following the Participant’s death.

3.3 SHAREHOLDER RIGHTS

A Participant shall not have any of the rights of a shareholder (including the right to vote or receive dividends) with respect to Common Shares covered by an Award until the Participant becomes the holder of record of such shares. A Participant may be granted the right to receive dividend equivalents under Section 2.5 with respect to one or more outstanding Awards. However, any dividend or dividend equivalent payable in connection with an unvested Award shall not be paid until and unless the underlying Award vests and shall be subject to risk of forfeiture to the same extent as the underlying Award.

3.4 TAX WITHHOLDING

The Company’s obligation to deliver Common Shares, other securities or cash upon the exercise, issuance, vesting or settlement of an Award under the Plan shall be subject to the satisfaction of all applicable Withholding Tax requirements. The Company (or any Parent or Subsidiary employing or retaining the Participant) shall have the right and is hereby authorized to withhold, from any cash, Common Shares, other securities or other property issuable or deliverable under any Award or from any compensation or other amounts owing to the Participant, the amount (in cash, Common Shares, other securities or other property) of any required Withholding Taxes in respect of an Award and to take such other action as may be necessary in the opinion of the Plan Administrator to satisfy all obligations for the payment of such Withholding Taxes. Without limiting the generality of the foregoing, the Plan Administrator may, in its sole discretion, permit a Participant to satisfy the foregoing Withholding Tax liability in whole or in part by (A) the delivery of Common Shares previously acquired by such individual (other than in connection with the exercise, issuance, vesting or settlement triggering the Withholding Taxes) with an aggregate Fair Market Value equal to the Withholding Taxes or (B) having the Company withhold, from the Common Shares otherwise issuable upon the issuance, exercise, vesting or settlement of such Award, a portion of those shares with an aggregate Fair Market Value at the time of delivery equal to the Withholding Taxes, in each case at a withholding rate determined by the Plan Administrator but in no event to exceed the maximum statutory rate applicable to the Participant.

3.5 SHARE ESCROW/LEGENDS

Unvested shares may, in the Plan Administrator’s discretion, be held in escrow by the Company until the Participant’s interest in such shares vests or may be issued directly to the Participant with restrictive legends on the certificates evidencing those unvested shares.

3.6 EFFECTIVE DATE AND TERM OF THE PLAN

(a) The Plan became effective on the Plan Effective Date. The Plan was amended in 2019, 2021, 2022, 2023, 2024 and 2025 to increase the share reserve and the Company’s shareholders approved the amendments at the 2019 Annual Shareholders Meeting, 2021 Annual Shareholders Meeting, 2022 Annual Shareholders Meeting, 2023 Annual Shareholders Meeting, 2024 Annual Shareholders Meeting,

(b) The Plan shall terminate upon the earliest to occur of (i) the date immediately preceding the tenth anniversary of the Plan Effective Date, (ii) the date on which all shares available for issuance under the Plan shall have been issued as fully vested shares, (iii) the termination of all outstanding Awards in connection with a Change in Control, or (iii) the termination of the Plan by the Board. Should the Plan terminate under subsection (i) above, then all Awards outstanding at that time shall continue to have force and effect in accordance with the provisions of the documents evidencing those Awards.

3.7 TERMINATION AND AMENDMENT OF THE PLAN

(a) The Board shall have complete and exclusive power and authority to terminate the Plan at any time. The Board shall also have complete and exclusive power and authority to amend or modify the Plan in any or all respects, subject to shareholder approval to the extent required under applicable law or regulation or pursuant to the listing standards of the Stock Exchange on which the Common Shares are at the time primarily traded. However, no such amendment or modification shall adversely affect the rights and obligations with respect to Awards at the time outstanding under the Plan unless the Participant consents to such amendment or modification.

(b) The Compensation Committee shall have the discretionary authority to adopt and implement from time to time such addenda or subplans to the Plan as it may deem necessary in order to bring the Plan into compliance with applicable laws and regulations of any foreign jurisdictions in which Awards are to be made under the Plan and/or to obtain favorable tax treatment in those foreign jurisdictions for the individuals to whom the Awards are made.

(c) Awards may be made under the Plan that involve Common Shares in excess of the number of shares then available for issuance under the Plan, provided no shares shall actually be issued pursuant to those Awards until the number of Common Shares available for issuance under the Plan is sufficiently increased by shareholder approval of an amendment of the Plan authorizing such increase. If such shareholder approval is not obtained within twelve (12) months after the date the first excess Award is made, then all Awards granted on the basis of such excess shares shall terminate and cease to be outstanding.

3.8 USE OF PROCEEDS

Any cash proceeds received by the Company from the sale of Common Shares under the Plan shall be used for general corporate purposes.

3.9 REGULATORY APPROVALS

(a) The implementation of the Plan, the granting of any Award under the Plan and the issuance of any Common Shares in connection with the issuance, exercise, vesting or settlement of any Award under the Plan shall be subject to the Company’s procurement of all approvals and permits required by regulatory authorities having jurisdiction over the Plan, the Awards made under the Plan and the Common Shares issuable pursuant to those Awards.

(b) No Common Shares or other assets shall be issued or delivered under the Plan unless and until there shall have been compliance with all applicable requirements of applicable securities

A - 15

laws, and all applicable listing requirements of any Stock Exchange on which the Common Shares are then listed for trading.

3.10 NO EMPLOYMENT/SERVICE RIGHTS

Nothing in the Plan shall confer upon the Participant any right to continue in Service for any period of specific duration or interfere with or otherwise restrict in any way the rights of the Company (or any Parent or Subsidiary employing or retaining such person) or of the Participant, which rights are hereby expressly reserved by each, to terminate such person’s Service at any time for any reason, with or without cause.

3.11 RECOUPMENT

Participants shall be subject to any clawback, recoupment or other similar policy adopted by the Board as in effect (and as modified) from time to time and Awards and any cash, Common Shares or other property or amounts due, paid or issued to a Participant shall be subject to the terms of such policy, as in effect (and as modified) from time to time.

APPENDIX B

ALPHA AND OMEGA SEMICONDUCTOR LIMITED

2018 EMPLOYEE SHARE PURCHASE PLAN

(As amended and restated effective November 17, 2026)

I.PURPOSE OF THE PLAN

This 2018 Employee Share Purchase Plan is intended to promote the interests of Alpha and Omega Semiconductor Limited, a company incorporated and existing under the laws of the Islands of Bermuda, by providing eligible employees with the opportunity to acquire a proprietary interest in the Company.

The Company intends that the Plan qualify as an “employee stock purchase plan” under Code Section 423 for one or more specified offerings made under the Plan. The Company may, however, establish one or more offerings under the Plan that are not designed to comply with the requirements of Code Section 423 but are intended to comply with the tax, securities and other compliance requirements of, and obtain tax and other objectives in, the foreign jurisdictions in which those offerings are conducted in order to allow participants in such offerings to purchase shares in a manner similar to the Plan. Such offerings shall be separate from any offering designed to comply with the Code Section 423 requirements but may be conducted concurrently with any such offering.

The Plan shall serve as the successor to the Company’s Employee Share Purchase Plan (the “Predecessor Plan”), and no additional offerings will commence under the Predecessor Plan on or after the Effective Date. All outstanding offerings under the Predecessor Plan, however, shall continue in effect in accordance with their terms, consistent with the Predecessor Plan.

Capitalized terms herein shall have the meanings assigned to such terms in the attached Appendix.

II. ADMINISTRATION OF THE PLAN

The Plan Administrator shall have full authority to interpret and construe any provision of the Plan and to adopt such rules and regulations for administering the Plan as it may deem necessary in order to comply with the requirements of Code Section 423 or other applicable law. Decisions of the Plan Administrator shall be final and binding on all parties having an interest in the Plan.

III. SHARES SUBJECT TO PLAN

A. The shares purchasable under the Plan shall be authorized but unissued or reacquired Common Shares, including Common Shares purchased on the open market. Subject to Section III.B, the number of Common Shares reserved for issuance over the term of the Plan shall not exceed Five Million Seven Hundred Thousand (5,700,000) shares.

B. Should any change be made to the Common Shares by reason of any share split, share dividend, recapitalization, combination of shares, exchange of shares, spin-off transaction, extraordinary distribution (whether in cash, securities or other property) or other change affecting the outstanding Common Shares as a class without the Company’s receipt of consideration, or should the value of the outstanding Common Shares be substantially reduced as a result of a spin-off transaction or

B - 1

an extraordinary dividend or distribution, then equitable adjustments shall be made to (i) the maximum number and class of securities issuable under the Plan, (ii) the maximum number and class of securities purchasable per Participant on any one Purchase Date, (iii) the maximum number and class of securities purchasable in total by all Participants on any one Purchase Date and (iv) the number and class of securities and the price per share in effect under each outstanding purchase right. The adjustments shall be made in such manner as the Plan Administrator deems appropriate in order to prevent the dilution or enlargement of benefits thereunder.

IV. OFFERING PERIODS

A. The Plan shall be implemented in one or more offerings. Offerings may be consecutive or overlapping. Each offering shall be in such form and shall contain such terms and conditions as the Plan Administrator shall deem appropriate. The terms and conditions of each offering may vary, and two or more offerings may run concurrently under the Plan, each with its own terms and conditions. In addition, special offerings may be established with respect to entities that are acquired by the Company (or any subsidiary of the Company) or under such other circumstances as the Plan Administrator deems appropriate. In no event, however, shall the terms and conditions of any offering contravene the express limitations and restrictions of the Plan, and to the extent required by Code Section 423, the Participants in each separate offering shall have equal rights and privileges under that offering in accordance with the requirements of Code Section 423(b)(5).

B. Common Shares shall be offered for purchase under each offering through a series of overlapping offering periods until such time as (i) the maximum number of Common Shares available for issuance under the Plan shall have been purchased or (ii) the Plan shall have been sooner terminated.

C. Each offering period shall be of such duration (not to exceed twenty-seven (27) months) as determined by the Plan Administrator prior to the commencement date of such offering period. Until such time as otherwise determined by the Plan Administrator, offering periods will commence on May 15 and November 15 (or if such dates are not Trading Days, then the first Trading day immediately following such dates) and will be of a duration of approximately twenty-four (24) months.

D. Each offering period shall consist of one or more successive Purchase Intervals as determined by the Plan Administrator prior to the commencement of such offering period. Until such time as otherwise determined by the Plan Administrator, Purchase Intervals will commence on May 15 and November 15 each year (or if such dates are not Trading Days, then the first Trading Day immediately following such dates) and end on November 14 and May 14, respectively (or if such dates are not Trading Days, then the immediately preceding Trading Day).

E. Should the Fair Market Value per Common Share on any Purchase Date within a particular offering period be less than the Fair Market Value per Common Share on the start date of that offering period, then the individuals participating in such offering period shall, immediately after the purchase of Common Shares on their behalf on such Purchase Date, be transferred from that offering period and automatically enrolled in the next offering period commencing on the next business day following such Purchase Date, provided and only if the Fair Market Value per Common Share on the start date of that new offering period is lower than the Fair Market Value per Common Share on the start date of the offering period in which they were currently enrolled.

F. The terms and conditions of each offering period may vary, and two or more offerings periods may run concurrently under the Plan, each with its own terms and conditions. In addition, special offering periods may be established with respect to entities that are acquired by the Company (or any subsidiary of the Company) or under such other circumstances as the Plan Administrator deems appropriate. In no event, however, shall the terms and conditions of any offering period contravene

B - 2

the express limitations and restrictions of the Plan, and to the extent required by Code Section 423, the Participants in each separate offering shall have equal rights and privileges under that offering in accordance with the requirements of Code Section 423(b)(5).

V. ELIGIBILITY

A. Purchase rights may be granted under the Plan only to Employees of the Company or an Affiliate. Unless otherwise determined by the Plan Administrator for an offering, each individual who is an Eligible Employee on the start date of any offering period under the Plan may enter that offering period on such start date. However, no Eligible Employee may participate in more than one offering period at any one time.

B. The date an individual enters an offering period shall be designated his or her Entry Date for purposes of that offering period.

C. Except as otherwise provided in Section IV.E above, an Eligible Employee must, in order to participate in the Plan for a particular offering period, complete and timely submit the enrollment forms prescribed by the Plan Administrator (which may include accessing the website designated by the Company and electronically completing and submitting the enrollment forms) and file such forms with the Plan Administrator (or its designate) on or before his or her scheduled Entry Date. However, unless sooner enrolled in the Plan in accordance with the foregoing, any Participant enrolled in any offering period outstanding under the Predecessor Plan on the Effective Date shall automatically, following the completion of that offering period, be enrolled upon the same terms and conditions in effect for that offering period, including the authorized rate of payroll deduction, on the start date of the first offering period under the Plan thereafter that incorporates those same terms and conditions.

VI. PAYROLL DEDUCTIONS

A. The payroll deduction authorized by the Participant for purposes of acquiring Common Shares during an offering period may be any multiple of one percent (1%) of the Cash Earnings or Base Salary (as determined by the Plan Administrator prior to the start of the offering period) paid to the Participant during each Purchase Interval within that offering period, up to a maximum of fifteen percent (15%). The deduction rate so authorized shall continue in effect throughout the offering period, except to the extent such rate is changed in accordance with the following guidelines:

(i) The Participant may, at any time during the offering period, reduce his or her rate of payroll deduction to become effective as soon as possible after filing the appropriate form with the Plan Administrator. Unless otherwise determined by the Plan Administrator for an offering, the Participant may not, however, effect more than one (1) such reduction per Purchase Interval.

(ii) The Participant may, prior to the commencement of any new Purchase Interval within the offering period or prior to the start date of any new offering period, increase the rate of his or her payroll deduction by filing the appropriate form with the Plan Administrator. The new rate (which may not exceed the maximum payroll deduction percentage in effect for that offering period) shall become effective on the start date of the first Purchase Interval or first offering period (if earlier) following the filing of such form.

(iii) The Participant may at any time reduce his or her rate of payroll deduction to 0%. Such reduction shall become effective as soon as administratively practicable following the filing of the appropriate form with the Plan Administrator. The Participant’s existing payroll

B - 3

deductions for the Purchase Interval in which such reduction occurs shall be applied to the purchase of Common Shares on the next scheduled Purchase Date.

B. Payroll deductions shall begin on the first pay day administratively feasible following the Participant’s Entry Date and shall (unless sooner terminated by the Participant) continue through the pay day ending with or immediately prior to the last day of that offering period. The amounts so collected shall be credited to the Participant’s book account under the Plan, but no interest shall be paid on the balance from time to time outstanding in such account unless otherwise required by applicable law. The amounts collected from the Participant shall not be required to be held in any segregated account or trust fund and may be commingled with the general assets of the Company and used for general corporate purposes unless otherwise required by applicable law.

C. Payroll deductions (together with any permitted contributions) shall automatically cease upon the termination of the Participant’s purchase right in accordance with the provisions of the Plan.

D. The Plan Administrator may permit Employees in one or more offerings to contribute to the Plan by means other than payroll deductions.

E. The Participant’s acquisition of Common Shares under the Plan on any Purchase Date shall neither limit nor require the Participant’s acquisition of Common Shares on any subsequent Purchase Date, whether within the same or a different offering period.

VII. PURCHASE RIGHTS

A. Grant of Purchase Rights. A Participant shall be granted a separate purchase right for each offering period in which he or she is enrolled. The purchase right shall be granted on the Participant’s Entry Date and shall provide the Participant with the right to purchase Common Shares, in a series of one or more successive installments during that offering period, upon the terms set forth below.

Under no circumstances shall purchase rights be granted under the Plan to any Eligible Employee if such individual would, immediately after the grant, own (within the meaning of Code Section 424(d)) or hold outstanding options or other rights to purchase, shares possessing five percent (5%) or more of the total combined voting power or value of all classes of shares of the Company or any Affiliate.

B. Exercise of the Purchase Right. Each purchase right shall be automatically exercised on each successive Purchase Date within the offering period, and Common Shares shall accordingly be purchased on behalf of each Participant on each such Purchase Date. The purchase shall be effected by applying the Participant’s payroll deductions (or, to the extent applicable, his or her lump sum contribution) for the Purchase Interval ending on such Purchase Date to the purchase of whole Common Shares at the purchase price in effect for the Participant for that Purchase Date.

C. Purchase Price. The purchase price per share at which Common Shares will be purchased on the Participant’s behalf on each Purchase Date within the particular offering period in which he or she is enrolled shall be determined by the Plan Administrator and shall not be less than eighty-five percent (85%) of the lower of (i) the Fair Market Value per Common Share on the Participant’s Entry Date or (ii) the Fair Market Value per Common Share on that Purchase Date. Unless such time as otherwise determined by the Plan Administrator the purchase price per share on any Purchase Date shall be equal to eighty-five percent (85%) of the lower of (i) the Fair Market Value per Common Share on the Participant’s Entry Date or (ii) the Fair Market Value per Common Share on that Purchase Date.

B - 4

D. Number of Purchasable Shares. The number of Common Shares purchasable by a Participant on each Purchase Date during the particular offering period in which he or she is enrolled shall be the number of whole shares obtained by dividing the amount collected from the Participant through payroll deductions during the Purchase Interval ending with that Purchase Date (or, to the extent applicable, his or her lump sum contributions) by the purchase price in effect for the Participant for that Purchase Date. However, the maximum number of Common Shares purchasable per Participant on any one Purchase Date within such offering period shall not exceed 875 shares and the maximum number of Common Shares purchasable in total by all Participants on any one Purchase Date within such offering period shall not exceed 300,000 shares, with each such limitation subject to periodic adjustments in the event of certain changes in the Company’s capitalization. The Plan Administrator shall have the discretionary authority, exercisable prior to the start of any offering period under the Plan, to increase or decrease the limitations to be in effect for the number of shares purchasable per Participant and in total by all Participants on each Purchase Date within that offering period.

E. Excess Payroll Deductions. Any payroll deductions (or contributions) not applied to the purchase of Common Shares on any Purchase Date because they are not sufficient to purchase a whole Common Share or by reason of the limitation on the maximum number of shares purchasable per Participant or in total by all Participants on the Purchase Date shall be promptly refunded.

F. Suspension of Payroll Deductions. In the event that a Participant is, by reason of the accrual limitations in Article VIII, precluded from purchasing additional Common Shares on one or more Purchase Dates during the offering period in which he or she is enrolled, then no further payroll deductions (or contributions) shall be collected from such Participant with respect to those Purchase Dates. The suspension of such deductions (or contributions) shall not terminate the Participant’s purchase right for the offering period in which he or she is enrolled, and payroll deductions (or, to the extent applicable, contributions) shall automatically resume on behalf of such Participant once he or she is again able to purchase shares during that offering period in compliance with the accrual limitations of Article VIII.

G. Withdrawal from Offering Period. The following provisions shall govern the Participant’s withdrawal from an offering period:

(i) A Participant may withdraw from the offering period in which he or she is enrolled at any time prior to the next scheduled Purchase Date by filing the appropriate form with the Plan Administrator (or its designate), and no further payroll deductions (or contributions) shall be collected from the Participant with respect to that offering period. Any payroll deductions (or contributions) collected during the Purchase Interval in which such withdrawal occurs shall, at the Participant’s election, be immediately refunded or held for the purchase of shares on the next Purchase Date. If no such election is made at the time of such withdrawal, then the payroll deductions (or contributions) collected from the Participant during the Purchase Interval in which such withdrawal occurs shall be refunded as soon as possible.

(ii) The Participant’s withdrawal from a particular offering period shall be irrevocable, and the Participant may not subsequently rejoin that offering period at a later date. In order to resume participation in any subsequent offering period, such individual must re-enroll in the Plan (by making a timely filing of the prescribed enrollment forms) on or before his or her scheduled Entry Date into that offering period.

B - 5

H. Termination of Purchase Right. The following provisions shall govern the termination of outstanding purchase rights:

(i) Should the Participant cease to remain an Eligible Employee for any reason (including death, disability or change in status) while his or her purchase right remains outstanding, then that purchase right shall immediately terminate, and all of the Participant’s payroll deductions (or, to the extent applicable, his or her lump sum contributions) for the Purchase Interval in which the purchase right so terminates shall be immediately refunded.

(ii) However, should the Participant cease to remain in active service by reason of an approved unpaid leave of absence, then the Participant shall have the right, exercisable up until the last business day of the Purchase Interval in which such leave commences, to (a) withdraw all the payroll deductions (or contributions) collected to date on his or her behalf for that Purchase Interval or (b) have such funds held for the purchase of shares on his or her behalf on the next scheduled Purchase Date. Unless otherwise determined by the Plan Administrator for one or more offerings, in no event, however, shall any further payroll deductions be collected on the Participant’s behalf during such leave. Upon the Participant’s return to active service (x) within three (3) months following the commencement of such leave or (y) prior to the expiration of any longer period for which such Participant has a right to reemployment with the Company (or an Affiliate) provided by statute or contract, his or her payroll deductions under the Plan shall automatically resume (and the Participant may resume contributions to the extent permitted) at the rate in effect at the time the leave began, unless the Participant withdraws from the Plan prior to his or her return. Unless otherwise determined by the Plan Administrator for one or more offerings, an individual who returns to active employment following a leave of absence that exceeds in duration the applicable (x) or (y) time period will be treated as a new Employee for purposes of subsequent participation in the Plan and must accordingly re-enroll in the Plan (by making a timely filing of the prescribed enrollment forms) on or before his or her scheduled Entry Date into the offering period.

I. Change in Control. Each outstanding purchase right shall automatically be exercised, immediately prior to the effective date of any Change in Control, by applying the payroll deductions of each Participant (or, to the extent applicable, his or her lump sum contributions) for the Purchase Interval in which such Change in Control occurs to the purchase of whole Common Shares at the purchase price per share in effect for that Purchase Interval. However, any applicable limitation on the number of Common Shares purchasable per Participant shall continue to apply to any such purchase, but not the limitation applicable to the maximum number of Common Shares purchasable in total by all Participants on any one Purchase Date.

The Company shall use its best efforts to provide at least ten (10) days’ prior written notice of the occurrence of any Change in Control, and the Participants shall, following the receipt of such notice, have the right to terminate their outstanding purchase rights prior to the effective date of the Change in Control.

J. Proration of Purchase Rights. Should the total number of Common Shares to be purchased pursuant to outstanding purchase rights on any particular date exceed the number of shares then available for issuance under the Plan, the Plan Administrator shall make a pro-rata allocation of the available shares on a uniform and nondiscriminatory basis, and the payroll deductions of each Participant, to the extent in excess of the aggregate purchase price payable for the Common Shares pro-rated to such individual, shall be refunded.

K. ESPP Brokerage Account. The Plan Administrator shall have the discretionary authority to require that the shares purchased on behalf of each Participant be deposited directly into a

B - 6

brokerage account which the Company shall establish for the Participant at a Company-designated brokerage firm. The account will be known as the ESPP Brokerage Account, and any shares deposited in the Participant’s ESPP Broker Account must remain in that account until the earliest to occur of (i) the date those shares are to be sold or transferred by gift, (ii) the date on which the requisite holding period necessary to avoid a disqualifying disposition of those shares under the federal tax laws has been satisfied, or (iii) the date of the Participant’s death.

L. Assignability. The purchase right shall be exercisable only by the Participant and shall not be assignable or transferable by the Participant.

M. Shareholder Rights. A Participant shall have no shareholder rights with respect to the shares subject to his or her outstanding purchase right until the shares are purchased on the Participant’s behalf in accordance with the provisions of the Plan and the Participant has become a holder of record of the purchased shares.

N. Withholding Taxes. The Company’s obligation to deliver shares upon exercise of a purchase right under the Plan shall be subject to the satisfaction of all income, employment and payroll taxes, social insurance, social security, national insurance and other contributions, payment on account obligations or other payments required to be collected, withheld or accounted for in connection with the purchase right. The Company or appropriate Affiliate may, but shall not be obligated to, withhold from any compensation or other accounts payable to the Participant the amount necessary to satisfy such obligations.

VIII. ACCRUAL LIMITATIONS

A. No Participant shall be entitled to accrue rights to acquire Common Shares pursuant to any purchase right outstanding under this Plan if and to the extent such accrual, when aggregated with (i) rights to purchase Common Shares accrued under any other purchase right granted under this Plan and (ii) similar rights accrued under other employee share purchase plans (within the meaning of Code Section 423) of the Company or any Affiliate, would otherwise permit such Participant to purchase more than Twenty-Five Thousand Dollars ($25,000.00) worth of shares of the Company or any Affiliate (determined on the basis of the Fair Market Value per share on the date or dates such rights are granted) for each calendar year such rights are at any time outstanding.

B. For purposes of applying such accrual limitations to the purchase rights granted under the Plan, the following provisions shall be in effect:

(i) The right to acquire Common Shares under each outstanding purchase right shall accrue in a series of installments on each successive Purchase Date during the offering period in which such right remains outstanding.

(ii) No right to acquire Common Shares under any outstanding purchase right shall accrue to the extent the Participant has already accrued in the same calendar year the right to acquire Common Shares under one or more other purchase rights at a rate equal to Twenty-Five Thousand Dollars ($25,000.00) worth of Common Shares (determined on the basis of the Fair Market Value per share on the date or dates of grant) for each calendar year such rights were at any time outstanding.

C. If by reason of such accrual limitations, any purchase right of a Participant does not accrue for a particular Purchase Interval, then the payroll deductions (or contributions) that the Participant made during that Purchase Interval with respect to such purchase right shall be promptly refunded.

B - 7

D. In the event there is any conflict between the provisions of this Article and one or more provisions of the Plan or any instrument issued thereunder, the provisions of this Article shall be controlling.
