Notice of Extraordinary General Meeting of Shareholders

To Be Held on August 26, 2026 at 11.00AM, Eastern Standard Time

QUESTIONS AND ANSWERS ABOUT THE EXTRAORDINARY GENERAL MEETING AND THE PROPOSALS

The following are answers to some questions that you, as a shareholder of Garden Stage Limited (“GSIW” or the “Company”), may have regarding the Proposals and related matters being considered at GSIW’s extraordinary general meeting of shareholders, which is referred to herein as the “EGM”.

Shareholders are encouraged to vote as soon as possible after carefully reviewing this proxy statement. If GSIW shareholders fail to approve a resolution, such resolution cannot be passed and approved.

If you are a registered shareholder, meaning that you hold your shares in certificate form, you have four voting options:

If you hold your shares through an account with a bank or broker, your ability to vote by the Internet depends on their voting procedures. Please follow the directions that your bank or broker provides.

For a discussion of the rules regarding the voting of shares held by beneficial owners, please see the question below entitled “If I am a beneficial owner of GSIW ordinary shares, what happens if I don’t provide voting instructions? What is discretionary voting? What is a broker non-vote?”

Abstentions and broker non-votes will count for purposes of determining quorum but will have no effect on the outcome of the vote because abstentions and broker non-votes do not count as votes cast.

THE EXTRAORDINARY GENERAL MEETING

Date, Time and Place of the EGM

The EGM will be held on August 26, 2026 at 11:00 P.M., Hong Kong Time (11 A.M. Eastern Time on August 26, 2026) in a virtual meeting format at: https://meeting.vstocktransfer.com/GARDENSTAGEAUG26 .

Purpose of the EGM

At the EGM, the Company is asking its shareholders as of the record date of 29 July 2026 (the “Record Date”) to consider, vote upon and approve the following resolutions:

Record Date; Shares Entitled to Vote; Quorum

Shareholders will be entitled to vote or direct votes to be cast at the EGM if they owned GSIW ordinary shares on the Record Date. Shareholders will have one vote for each share of GSIW Class A ordinary share owned at the close of business on the Record Date, and one hundred votes for each share of GSIW Class B ordinary share owned at the close of business on the Record Date. If your shares are held in “street name” or are in a margin or similar account, you should contact your broker to ensure that votes related to the shares you beneficially own are properly counted.

As of the close of business on the Record Date, there were 1,462,399 outstanding GSIW Class A ordinary shares, and 9,250,000 outstanding GSIW Class B ordinary shares.

A quorum of GSIW shareholders is necessary to hold a valid meeting. The presence in person or by proxy of shareholders holding not less than an aggregate of one-third of the class or series of voting shares in the Company at the EGM is necessary to constitute a quorum. Abstentions will count as present for the purposes of establishing a quorum but will be disregarded for purposes of determining the results of voting.

Vote Required; Abstentions and Broker Non-Votes

The approval of the first proposal, increase of the authorized share capital, the third proposal, authorization of the transfer agent and share registrar, and registered office provider, and the fourth proposal, adjournment of EGM, requires that a simple majority of the votes cast at the EGM be voted “For” the proposal, provided we have quorum for the meeting.

The approval of the second proposal, adoption of the Third M&A, requires that a two-thirds majority of the votes cast at the EGM be voted “For” the proposal, provided we have quorum for the meeting.

Abstentions and broker non-votes will count for purposes of determining quorum but will have no effect on the outcome of the vote because abstentions and broker non-votes do not count as votes cast.

Voting of Proxies

If your shares are registered in your name with our transfer agent, VStock Transfer, LLC, you may cause your shares to be voted by returning a signed proxy card, or you may vote in person at the EGM. Additionally, you may submit electronically over the Internet a proxy authorizing the voting of your shares by following the instructions on your proxy card. You must have the enclosed proxy card available, and follow the instructions on the proxy card, in order to submit a proxy electronically over the Internet. Based on your proxy cards or Internet proxies, the proxy holders will vote your shares according to your directions.

Voting instructions are included on your proxy card. All shares represented by properly executed proxies received in time for the EGM will be voted at the EGM in accordance with the instructions of the shareholder.

If your shares are held in “street name” through a broker, bank or other nominee, you may vote through your broker, bank or other nominee by completing and returning the voting form provided by your broker, bank or other nominee, or by the Internet or telephone through your broker, bank or other nominee if such a service is provided. To vote via the Internet or telephone through your broker, bank or other nominee, you should follow the instructions on the voting form provided by your broker, bank or other nominee. If you do not return your bank’s, broker’s or other nominee’s voting form, do not vote via the Internet or telephone through your broker, bank or other nominee, if possible, and do not attend the EGM and vote in person with a proxy from your broker, bank or other nominee, your shares will not be counted for purposes of determining quorum or for purposes of the voting results.

Shareholders are encouraged to vote prior to the EGM using the methods described above. Voting in advance ensures your vote is counted and is not necessary to vote during the Virtual Meeting. However, if you wish to vote during the Virtual Meeting, the following instructions apply:

Revocability of Proxies

If you are a shareholder of record, you may change your vote or revoke your proxy at any time before it is voted at the EGM by:

Please note that to be effective, your new proxy card, fax or email voting instructions or written notice of revocation must be received by us prior to the EGM and, in the case of internet or mail voting instructions, must be received before 11:59 P.M. Hong Kong time on August 25, 2026 (11:59 A.M. Eastern time on August 25, 2026). If you have submitted a proxy, your appearance at the EGM, in the absence of voting in person or submitting an additional proxy or revocation, will not have the effect of revoking your prior proxy.

If you hold your ordinary shares in “street name,” you should contact your bank, broker or other nominee for instructions regarding how to change your vote. You may also vote in person at the EGM if you obtain a valid “legal” proxy from your bank, broker or other nominee. Any adjournment, recess or postponement of the EGM for the purpose of soliciting additional proxies will allow GSIW shareholders who have already sent in their proxies to revoke them at any time prior to their use at the EGM as adjourned, recessed or postponed.

Board of Directors’ Recommendation

After careful consideration, the Company’s Board has determined that the proposed resolutions are fair to, and in the best interest of, the Company and its shareholders. They unanimously recommend that you vote or give instruction to vote:

“FOR” the increase in authorized share capital;

“FOR” the adoption of third amended and restated memorandum and articles of association;

“FOR” the authorization of transfer agent and share registrar and registered office provider; and

“FOR” the adjournment of EGM.

Solicitation of Proxies

The expense of soliciting proxies in the enclosed form will be borne by GSIW. Proxies may also be solicited by some of our directors, officers and employees, personally or by telephone, facsimile, email or other means of communication. No additional compensation will be paid for such services.

Other Matters

At this time, we know of no other matters to be submitted at the EGM.

Householding of EGM Materials

Unless we have received contrary instructions, we may send a single copy of this proxy statement and notice to any household at which two or more shareholders reside if we believe the shareholders are members of the same family. Each shareholder in the household will continue to receive a separate proxy card. This process, known as “house holding”, reduces the volume of duplicate information received at your household and helps to reduce our expenses.
