FIVE9, INC.

2026 Inducement Equity Incentive Plan

Adopted by the Board of Directors: June 5, 2026

1.	GENERAL.

(a) Eligible Award Recipients. Awards under the Plan may only be granted to Employees who satisfy each of the following conditions: (i) the grant of an Award under the Plan constitutes a material inducement to such person’s decision to enter into employment with the Company or an Affiliate and (ii) prior to entering into such employment, such person either (a) has not previously served as a Director or an Employee of the Company or any Affiliate, or (b) is a former Employee who is returning to employment with the Company or an Affiliate following a bona fide period of non-employment.

(b) Available Awards. The Plan provides for the grant of the following Awards: (i) Options, (ii) Stock Appreciation Rights, (iii) Restricted Stock Awards, (iv) Restricted Stock Unit Awards, (v) Performance Stock Awards, and (vi) Other Stock Awards.

(c) Purpose. The purpose of this Plan is to provide awards as an inducement material to certain employees of the Company who are entering into employment with the Company or any of its Affiliates and to provide incentives for such persons to exert maximum efforts for the success of the Company and any Affiliate, and provide a means by which the eligible recipients may benefit from increases in value of the Common Stock. This Plan, and the Awards granted under this Plan, are intended to comply with Rule 5635(c)(4) of the Listing Rules, which provide an exception to the Listing Rules shareholder approval requirements for the issuance of securities in connection with grants to employees of the Company and its Affiliates where such grants are inducements material to such persons’ entering into employment with the Company or its Affiliates (and, notwithstanding anything in this Plan to the contrary, this Plan shall be administered and interpreted consistent with such intention).

2.	ADMINISTRATION.

(a) Administration by Committee. The Committee will administer the Plan. The Committee may delegate administration of the Plan as provided in Section 2(c).

(b) Powers of Committee. The Committee will have the power, subject to, and within the limitations of, the express provisions of the Plan and the requirements for inducement awards under the Listing Rules:

(i) To determine: (A) who will be granted Awards; (B) when and how each Award will be granted; (C) what type of Award will be granted; (D) the provisions of each Award (which need not be identical), including when a person will be permitted to exercise or otherwise receive Common Stock under the Award; (E) the number of shares of Common Stock subject to an Award; and (F) the Fair Market Value applicable to an Award.

(ii) To construe and interpret the Plan and Awards granted under it, and to establish, amend and revoke rules and regulations for administration of the Plan and Awards. The Committee, in the exercise of these powers, may correct any defect, omission or inconsistency in the Plan or in any Award Agreement, in a manner and to the extent it will deem necessary or expedient to make the Plan or Award fully effective.

(iii) To settle all controversies regarding the Plan and Awards granted under it.

(iv) To accelerate, in whole or in part, the time at which an Award may be exercised or vest (or at which shares of Common Stock may be issued).

(v) To amend, suspend or terminate the Plan at any time. Except as otherwise provided in the Plan or an Award Agreement, amendment, suspension or termination of the Plan will not materially impair a Participant’s rights under his or her then-outstanding Award without his or her written consent. A Participant’s rights will not be deemed to have been impaired by any such amendment if the Committee, in its sole discretion, determines that the amendment, taken as a whole, does not materially impair the Participant’s rights. In addition, subject to the limitations of applicable law, if any, the Committee may amend the terms of any one or more Awards without the affected Participant’s consent (A) to clarify the manner of exemption from, or to bring the Award into compliance with Section 409A; (B) to correct clerical or typographical errors; or (C) to comply with other applicable laws or listing requirements.

(vi) Generally, to exercise such powers and to perform such acts as the Committee deems necessary or expedient to promote the best interests of the Company and that are not in conflict with the provisions of the Plan or Awards.

(vii) To adopt such procedures and sub-plans as are necessary or appropriate to permit participation in the Plan by Employees who are foreign nationals or employed outside the United States.

(viii) To effect, with the consent of any adversely affected Participant, (A) the reduction of the exercise, purchase or strike price of any outstanding Award; (B) the cancellation of any outstanding Award and the grant in substitution therefor of a new (1) Option or SAR, (2) Restricted Stock Award, (3) Restricted Stock Unit Award, (4) Other Stock Award and/or (5) award of other valuable, equity-linked consideration determined by the Committee, in its sole discretion, with any such substituted award (x) covering the same or a different number of shares of Common Stock as the cancelled Award and (y) granted under the Plan or another equity or compensatory plan of the Company; or (C) any other action that is treated as a repricing under generally accepted accounting principles.

(c) Delegation by Committee. The Committee may delegate some or all of the administration of the Plan to the fullest extent permitted by law and the requirements for inducement awards under the Listing Rules. Any delegation of administrative powers will be reflected in resolutions, not inconsistent with the provisions of the Plan, adopted from time to time by the Committee. The Committee may retain the authority to concurrently administer the Plan with its delegate and may, at any time, revest in the Committee some or all of the powers previously delegated.

(d) Effect of Committee’s Decision. All determinations, interpretations and constructions made by the Committee in good faith will not be subject to review by any person and will be final, binding and conclusive on all persons.

3.	SHARES SUBJECT TO THE PLAN.

(a) Share Reserve.

(i) Subject to Section 9(a) relating to Capitalization Adjustments, the aggregate number of shares of Common Stock that may be issued pursuant to Stock Awards shall consist of a new share reserve of 2,900,000 shares of Common Stock (the “Share Reserve”).

(ii) For clarity, the Share Reserve is a limitation on the number of shares of Common Stock that may be issued pursuant to the Plan. Accordingly, this Section 3(a) does not limit the granting of Stock Awards except as provided in Section 7(a) (that is, availability of shares).

(b) Reversion of Shares to the Share Reserve. Shares will return to the Plan, and will not reduce (or otherwise offset) the number of shares of Common Stock that may be available for issuance under the Plan, if the Stock Award, or any portion thereof:

(i) expires or otherwise terminates without all of the shares covered by such Stock Award having been issued; or

(ii) is forfeited back to or repurchased by the Company because of the failure to meet a contingency or condition required to vest such shares in the Participant.

(c) Source of Shares. The stock issuable under the Plan will be shares of authorized but unissued or reacquired Common Stock, including shares repurchased by the Company on the open market or otherwise.

4.	ELIGIBILITY.

The only persons eligible to participate in the Plan and receive grants thereunder are Employees who satisfy the standards for inducement awards under Rule 5635(c)(4) of the Listing Rules. A person who previously served as an Employee or Director will not be eligible to receive Awards under the Plan, other than following a bona fide period of non-employment. Stock Awards may not be granted to Employees who are providing Continuous Service only to any “parent” of the Company, as such term is defined in Rule 405 of the Securities Act, unless (i) the stock underlying such Stock Awards is “service recipient stock” under Section 409A of the Code (for example, because the Stock Awards are granted pursuant to a Change in Control such as a spin off transaction), (ii) the Company, in connection with its legal counsel, has determined that such Stock Awards are otherwise exempt from Section 409A of the Code, or (iii) the Company, in connection with its legal counsel, has determined that such Stock Awards comply with the requirements of Section 409A of the Code.

5.	OPTIONS AND STOCK APPRECIATION RIGHTS.

Each Option or SAR will be in such form and will contain such terms and conditions as the Committee deems appropriate. The provisions of separate Options or SARs need not be identical. However, each Award Agreement will conform to (through incorporation of provisions hereof by reference in the applicable Award Agreement or otherwise) the substance of each of the following provisions:

(a) Term. No Option or SAR will be exercisable after the expiration of ten years from the date of its grant or such shorter period specified in the Award Agreement.

(b) Exercise Price. The exercise or strike price of each Option or SAR will be not less than 100% of the Fair Market Value of the Common Stock subject to the Option or SAR on the date the Award is granted. Each SAR will be denominated in shares of Common Stock equivalents.

(c) Purchase Price for Options. The purchase price of Common Stock acquired on the exercise of an Option may be paid, to the extent permitted by applicable law and as determined by the Committee in its sole discretion, by any combination of the methods of payment set forth below. The Committee will have the authority to grant Options that do not permit all of the following methods of payment (or otherwise restrict the ability to use certain methods) and to grant Options that require the consent of the Company to use a particular method of payment. The permitted methods of payment are as follows:

(i) by cash, check, bank draft, electronic funds, wire transfer, or money order payable to the Company;

(ii) through a program developed under Regulation T as established by the Federal Reserve Board that, prior to the issuance of the stock subject to the Option, results in either the receipt of cash (or check) by the Company or the receipt of irrevocable instructions to pay the aggregate exercise price to the Company from the sales proceeds (sometimes called a “same day sale” or “sell to cover”);

(iii) by a “net exercise” arrangement by which the Company will reduce the number of shares of Common Stock received upon exercise by the largest whole number of shares with a fair market value that does not exceed the aggregate exercise price, coupled with a cash payment for any remaining balance of the aggregate exercise price not satisfied by such reduction in the number of whole shares to be issued (and for clarity, these shares used to pay the exercise price will be issued at exercise, and then immediately reacquired by the Company);

(iv) by delivery to the Company (either by actual delivery or attestation) of other shares of Common Stock already owned by the Award holder; or

(v) in any other form of legal consideration that may be acceptable to the Committee and specified in the applicable Award Agreement.

(d) Exercise and Payment of a SAR. To exercise any outstanding SAR, the Participant must provide written notice of exercise to the Company in compliance with the provisions of the Stock Appreciation Right Agreement evidencing such SAR. The appreciation distribution payable on the exercise of a SAR will be not greater than an amount equal to the excess of (A) the aggregate fair market value (on the date of the exercise of the SAR) of a number of shares of Common Stock equal to the number of Common Stock equivalents in which the Participant is vested under such SAR, and with respect to which the Participant is exercising the SAR on such date, over (B) the strike price. The appreciation distribution may be paid in Common Stock.

(e) Transferability of Options and SARs. The Committee may, in its sole discretion, impose such limitations on the transferability of Options and SARs as the Committee will determine. In the absence of such a determination by the Committee to the contrary, the following restrictions on the transferability of Options and SARs will apply:

(i) Restrictions on Transfer. An Option or SAR will not be transferable except by will or by the laws of descent and distribution (or pursuant to subsections (ii) and (iii) below), and will be exercisable during the lifetime of the Participant only by the Participant. The Committee may permit transfer of the Option or SAR in a manner that is not prohibited by applicable tax and securities laws. Except as explicitly provided herein, neither an Option nor a SAR may be transferred for consideration.

(ii) Domestic Relations Orders. Subject to the approval of the Committee, an Option or SAR may be transferred pursuant to the terms of a domestic relations order, official marital settlement agreement or other divorce or separation instrument as permitted by Treasury Regulations 1.421-1(b)(2).

(iii) Beneficiary Designation. Subject to the approval of the Committee, a Participant may, by delivering written notice to the Company, in a form approved by the Company (or the designated broker), designate a third party who, on the death of the Participant, will thereafter be entitled to exercise the Option or SAR and receive the Common Stock or other consideration resulting from such exercise. In the absence of such a designation, the executor or administrator of the Participant’s estate will be entitled to exercise the Option or SAR and receive the Common Stock or other consideration resulting from such exercise. However, the Company may prohibit designation of a beneficiary at any time, including due to any conclusion by the Company that such designation would be inconsistent with the provisions of applicable laws.

(f) Vesting Generally. The total number of shares of Common Stock subject to an Option or SAR may vest and therefore become exercisable in periodic installments that may or may not be equal. The Option or SAR may be subject to such other terms and conditions on the time or times when it may or may not be exercised (which may be based on the satisfaction of Performance Goals or other criteria) as the Committee may deem appropriate. The vesting provisions of individual Options or SARs may vary.

(g) Termination of Continuous Service. Except as otherwise provided in the applicable Award Agreement or other agreement between the Participant and the Company, if a Participant’s Continuous Service terminates (other than for Cause and other than upon the Participant’s death or Disability), the Participant may exercise his or her Option or SAR (to the extent that the Participant was entitled to exercise such Award as of the date of termination of Continuous Service) within the period of time ending on the earlier of (i) the date three months following the termination of the Participant’s Continuous Service and (ii) the expiration of the term of the Option or SAR as set forth in the Award Agreement. If, after termination of Continuous Service, the Participant does not exercise his or her Option or SAR within the applicable time frame, the Option or SAR will terminate. In all cases, the unvested piece of an Option or SAR will terminate on the termination of Continuous Service.

(h) Extension of Termination Date. If the exercise of an Option or SAR following the termination of the Participant’s Continuous Service (other than for Cause and other than upon the Participant’s death or Disability) would be prohibited at any time solely because the issuance of shares of Common Stock would violate the registration requirements under the Securities Act, then the Option or SAR will terminate on the earlier of (i) the expiration of a total period of three months (that need not be consecutive) after the termination of the Participant’s Continuous Service during which the exercise of the Option or SAR would not be in violation of such registration requirements, and (ii) the expiration of the term of the Option or SAR as set forth in the applicable Award Agreement. In addition, unless otherwise provided in a Participant’s Award Agreement, if the immediate sale of any Common Stock received on exercise of an Option or SAR following the termination of the Participant’s Continuous Service (other than for Cause and other than upon the Participant’s death or Disability) would violate the Company’s insider trading policy, then the Option or SAR will terminate on the earlier of (i) the expiration of a total period of three months (that need not be consecutive) after the termination of the Participant’s Continuous Service during which the sale of the Common Stock received upon exercise of the Option or SAR would not be in violation of the Company’s insider trading policy, or (ii) the expiration of the term of the Option or SAR as set forth in the applicable Award Agreement.

(i) Disability of Participant. Except as otherwise provided in the applicable Award Agreement or other agreement between the Participant and the Company, if a Participant’s Continuous Service terminates as a result of the Participant’s Disability, the Participant may exercise his or her Option or SAR (to the extent that the Participant was entitled to exercise such Option or SAR as of the date of termination of Continuous Service), but only within such period of time ending on the earlier of (i) the date 12 months following such termination of Continuous Service and (ii) the expiration of the term of the Option or SAR as set forth in the Award Agreement. If, after termination of Continuous Service, the Participant does not exercise his or her Option or SAR within the applicable time frame, the Option or SAR (as applicable) will terminate.

(j) Death of Participant. Except as otherwise provided in the applicable Award Agreement or other agreement between the Participant and the Company, if (i) a Participant’s Continuous Service terminates as a result of the Participant’s death, or (ii) the Participant dies within the period (if any) specified in the Award Agreement for exercisability after the termination of the Participant’s Continuous Service for a reason other than death, then the Option or SAR may be exercised (to the extent the Participant was entitled to exercise such Option or SAR as of the date of death) by the Participant’s estate, by a person who acquired the right to exercise the Option or SAR by bequest or inheritance or by a person designated to exercise the Option or SAR upon the Participant’s death, but only within the period ending on the earlier of (A) the date 12 months following the date of death and (B) the expiration of the term of such Option or SAR as set forth in the Award Agreement. If, after the Participant’s death, the Option or SAR is not exercised within the applicable time frame, the Option or SAR will terminate.

(k) Termination for Cause. Except as explicitly provided otherwise in a Participant’s Award Agreement, if a Participant’s Continuous Service is terminated for Cause, the Option or SAR will terminate upon the date on which the event giving rise to the termination for Cause first occurred, and the Participant will be prohibited from exercising his or her Option or SAR from and after the date on which the event giving rise to the termination for Cause first occurred (or, if required by law, the date of termination of Continuous Service).

(l) Non-Exempt Employees. If an Option or SAR is granted to an Employee who is a non-exempt employee for purposes of the Fair Labor Standards Act of 1938, as amended, the Option or SAR will not be first exercisable for any shares of Common Stock until at least six (6) months following the date of grant of the Option or SAR (although the Award may vest prior to such date). Consistent with the provisions of the Worker Economic Opportunity Act, (i) if such non-exempt Employee dies or suffers a Disability, (ii) upon a Change in Control in which such Option or SAR is not assumed, continued, or substituted, or (iii) upon the Participant’s retirement (as such term may be defined in the Participant’s Award Agreement or in another agreement between the Participant and the Company, or, if no such definition, in accordance with the Company’s then current employment policies and guidelines), the vested portion of any Options and SARs may be exercised earlier than six months following the date of grant. The foregoing provision is intended to operate so that any income derived by a non-exempt employee in connection with the exercise or vesting of an Option or SAR will be exempt from his or her regular rate of pay. If permitted and/or required for compliance with the Worker Economic Opportunity Act to ensure that any income derived by a non-exempt employee in connection with the exercise, vesting or issuance of any shares under any other Stock Award will be exempt from the employee’s regular rate of pay, the provisions of this paragraph will apply to all Stock Awards and are hereby incorporated by reference into such Award Agreements.

6.	STOCK AWARDS OTHER THAN OPTIONS AND SARS.

(a) Restricted Stock Awards. Each Award Agreement will be in such form and will contain such terms and conditions as the Committee deems appropriate. To the extent consistent with the Company’s bylaws, at the Committee’s election, shares of Common Stock may be (x) held in book entry form subject to the Company’s instructions until any restrictions relating to the Restricted Stock Award lapse; or (y) evidenced by a certificate, which certificate will be held

in such form and manner as determined by the Committee. The terms and conditions of Award Agreements may change from time to time, and the terms and conditions of separate Award Agreements need not be identical. Each Award Agreement will conform to (through incorporation of the provisions hereof by reference in the agreement or otherwise) the substance of each of the following provisions:

(i) Consideration. A Restricted Stock Award may be awarded in consideration for (A) cash, check, bank draft, electronic funds, wire transfer, or money order payable to the Company, (B) past services to the Company or an Affiliate, or (C) any other form of legal consideration that may be acceptable to the Committee, in its sole discretion, and permissible under applicable law.

(ii) Vesting. Shares of Common Stock awarded under the Restricted Stock Award may be subject to forfeiture to the Company in accordance with a vesting schedule to be determined by the Committee.

(iii) Termination of Participant’s Continuous Service. If a Participant’s Continuous Service terminates, the Company may receive through a forfeiture condition or a repurchase right any or all of the shares of Common Stock held by the Participant that have not vested as of the date of termination of Continuous Service under the terms of the Award Agreement.

(iv) Transferability. The right to acquire shares of Common Stock under a Restricted Stock Award will not be transferable by the Participant. Once the shares of Common Stock are issued, the Committee may allow the holder to transfer unvested shares, but only on the terms and conditions in the Award Agreement, and only so long as the Common Stock awarded under the Award Agreement remains subject to the terms of the Award Agreement in the hands of the recipient.

(v) Dividends. In the absence of an Award Agreement expressly providing otherwise, any dividends paid on Restricted Stock will be subject to the same vesting and forfeiture restrictions as apply to the shares subject to the Restricted Stock Award to which they relate.

(b) Restricted Stock Unit Awards. Each Award Agreement will be in such form and will contain such terms and conditions as the Committee will deem appropriate. The terms and conditions of Award Agreements may change from time to time, and the terms and conditions of separate Award Agreements need not be identical. Each Award Agreement will conform to (through incorporation of the provisions hereof by reference in the agreement or otherwise) the substance of each of the following provisions:

(i) Consideration. At the time of grant of a Restricted Stock Unit Award, the Committee will determine the consideration, if any, to be paid by the Participant upon delivery of each share of Common Stock subject to the Restricted Stock Unit Award. The consideration to be paid (if any) by the Participant for each share of Common Stock subject to a Restricted Stock Unit Award may be paid in any form of legal consideration that may be acceptable to the Committee, in its sole discretion, and permissible under applicable law.

(ii) Vesting. At the time of the grant of a Restricted Stock Unit Award, the Committee may impose such restrictions on or conditions to the vesting of the Restricted Stock Unit Award as it, in its sole discretion, deems appropriate.

(iii) Payment. A Restricted Stock Unit Award may be settled by the delivery of shares of Common Stock, their cash equivalent, any combination thereof or in any other form of consideration, as determined by the Committee and contained in the Award Agreement.

(iv) Additional Restrictions. At the time of the grant of a Restricted Stock Unit Award, the Committee, as it deems appropriate, may impose such restrictions or conditions that delay the delivery of the shares of Common Stock (or their cash equivalent) subject to a Restricted Stock Unit Award to a time after the vesting of such Restricted Stock Unit Award.

(v) Dividend Equivalents. Dividend equivalents may be credited in respect of shares of Common Stock covered by a Restricted Stock Unit Award, as determined by the Committee and contained in the Award Agreement. At the sole discretion of the Committee, such dividend equivalents may be converted into additional shares of Common Stock covered by the Restricted Stock Unit Award in such manner as determined by the Committee. Any additional shares covered by the Restricted Stock Unit Award credited by reason of such dividend equivalents will be subject to all of the same terms and conditions of the underlying Award Agreement to which they relate.

(vi) Termination of Participant’s Continuous Service. Except as otherwise provided in the applicable Award Agreement, the unvested portion of the Restricted Stock Unit Award will be forfeited upon the Participant’s termination of Continuous Service.

(c) Performance Stock Awards. A Performance Stock Award is a Stock Award that is payable (including that may be granted, vest or exercised) contingent on the attainment during a Performance Period of certain Performance Goals. A Performance Stock Award may, but need not, require the completion of a specified period of Continuous Service. The length of any Performance Period, the Performance Goals to be achieved during the Performance Period, and the measure of whether and to what degree such Performance Goals have been attained will be conclusively determined by the Committee in its sole discretion.

(d) Other Stock Awards. Other forms of Stock Awards valued in whole or in part by reference to, or otherwise based on, Common Stock, including the appreciation in value thereof (e.g., options or stock rights with an exercise price or strike price less than 100% of the Fair Market Value of the Common Stock at the time of grant) may be granted either alone or in addition to Stock Awards provided for under Section 5 and the preceding provisions of this Section 6. Subject to the provisions of the Plan, the Committee will have sole and complete authority to determine the persons to whom and the time or times at which such Other Stock Awards will be granted, the number of shares of Common Stock to be granted pursuant to such Other Stock Awards and all other terms and conditions of such Other Stock Awards.

7.	COVENANTS OF THE COMPANY.

(a) Availability of Shares. The Company will keep available at all times the number of shares of Common Stock reasonably required to satisfy then-outstanding Awards.

(b) Securities Law Compliance. To the extent reasonably practicable, the Company will seek to obtain from each regulatory commission or agency having jurisdiction over the Plan such authority as may be required to grant Stock Awards and to issue and sell shares of Common Stock upon exercise of the Stock Awards. However, this undertaking will not require the Company to register under the Securities Act the Plan, any Stock Award or any Common Stock issued or issuable pursuant to any such Stock Award. If, after reasonable efforts and at a reasonable cost, the Company is unable to obtain from any such regulatory commission or agency the authority that counsel for the Company deems necessary for the lawful issuance and sale of Common Stock under the Plan, the Company will be relieved from any liability for failure to issue and sell Common Stock upon exercise of such Stock Awards unless and until such authority is obtained. A Participant will not be eligible for the grant of an Award or the subsequent issuance of cash or Common Stock pursuant to the Award if such grant or issuance would be in violation of any applicable securities law.

(c) No Obligation to Notify or Minimize Taxes. The Company will have no duty or obligation to any Participant to advise such holder as to the time or manner of exercising such Stock Award. Furthermore, the Company will have no duty or obligation to warn or otherwise advise such holder of a pending termination or expiration of an Award or a possible period in which the Award may not be exercised. The Company has no duty or obligation to minimize the tax consequences of an Award to the holder of such Award.

8.	MISCELLANEOUS.

(a) Use of Proceeds from Sales of Common Stock. Proceeds from the sale of shares of Common Stock pursuant to Awards will constitute general funds of the Company.

(b) Corporate Action Constituting Grant of Awards. Corporate action constituting a grant by the Company of an Award to any Participant will be deemed completed as of the date of such corporate action, unless otherwise determined by the Committee, regardless of when the instrument, certificate, or letter evidencing the Award is communicated to, or actually received or accepted by, the Participant. In the event that the corporate records (e.g., Committee consents, resolutions or minutes) documenting the corporate action constituting the grant contain terms (e.g., exercise price, vesting schedule or number of shares) that are inconsistent with those in the Award Agreement as a result of a clerical error in the papering of the Award Agreement, the corporate records will control and the Participant will have no legally binding right to the incorrect term in the Award Agreement.

(c) Stockholder Rights. No Participant will be deemed to be the holder of, or to have any of the rights of a holder with respect to, any shares of Common Stock subject to an Award unless and until (i) such Participant has satisfied all requirements for exercise of, or the issuance of shares under, the Award pursuant to its terms, and (ii) the issuance of the Common Stock subject to such Award has been entered into the books and records of the Company.

(d) No Employment or Other Service Rights. Nothing in the Plan, any Award Agreement or any other instrument executed thereunder or in connection with any Award granted pursuant thereto will confer upon any Participant any right to continue to serve the Company or an Affiliate in the capacity in effect at the time the Award was granted or will affect the right of the Company or an Affiliate to terminate (i) the employment of an Employee with or without notice and with or without cause, (ii) the service of a Consultant pursuant to the terms of such Consultant’s agreement with the Company or an Affiliate, or (iii) the service of a Director pursuant to the bylaws of the Company or an Affiliate, and any applicable provisions of the corporate law of the state in which the Company or the Affiliate is incorporated, as the case may be.

(e) Change in Time Commitment. If a Participant’s regular level of time commitment in the performance of his or her services for the Company and any Affiliates is reduced (for example, and without limitation, if the Participant is an Employee of the Company and the Employee has a change in status from a full-time Employee to a part-time Employee) after the date of grant of any Award to the Participant, the Committee has the right in its sole discretion (and without the need to seek or obtain the consent of the affected Participant) to (x) make a corresponding reduction in the number of shares or cash amount subject to any portion of such Award that is scheduled to vest or become payable after the date of such change in time commitment, and (y) in lieu of or in combination with such a reduction, extend the vesting or payment schedule applicable to such Award. In the event of any such reduction, the Participant will have no right with respect to any portion of the Award that is so reduced.

(f) Investment Assurances. The Company may require a Participant, as a condition of exercising or acquiring Common Stock under any Award, (i) to give written assurances satisfactory to the Company as to the Participant’s knowledge and experience in financial and business matters and/or to employ a purchaser representative reasonably satisfactory to the Company who is knowledgeable and experienced in financial and business matters and that he or she is capable of evaluating, alone or together with the purchaser representative, the merits and risks of exercising the Award; and (ii) to give written assurances satisfactory to the Company stating that the Participant is acquiring Common Stock subject to the Award for the Participant’s own account and not with any present intention of selling or otherwise distributing the Common Stock. The foregoing requirements, and any assurances given pursuant to such requirements, will be inoperative if (A) the issuance of the shares upon the exercise or acquisition of Common Stock under the Award has been registered under a then currently effective registration statement under the Securities Act and any other applicable foreign securities laws, or (B) as to any particular requirement, a determination is made by counsel for the Company that such requirement need not be met in the circumstances under then applicable securities laws. The Company may, upon advice of counsel to the Company, place legends on stock certificates issued under the Plan as such counsel deems necessary or appropriate in order to comply with applicable securities laws, including, but not limited to, legends restricting the transfer of the Common Stock.

(g) Withholding Obligations. Unless prohibited by the terms of an Award Agreement or applicable law, the Company may, in its sole discretion, satisfy any federal, state or local tax withholding obligation relating to an Award by any of the following means or by a combination of such means: (i) causing the Participant to tender a cash payment; (ii) withholding shares of Common Stock from the shares of Common Stock issued or otherwise issuable to the Participant in connection with the Award; (iii) withholding cash from an Award settled in cash; (iv) withholding payment from any amounts otherwise payable to the Participant; or (v) by such other method as may be set forth in the Award Agreement. If shares of Common Stock are withheld to satisfy tax obligations, such shares will be deemed issued and then immediately tendered to the Company and no shares of Common Stock will be withheld for these purposes to the extent they have a value exceeding the minimum amount of tax required to be withheld by law (or such lesser amount as may be necessary to avoid classification of the Stock Award as a liability for financial accounting purposes). For clarity, no partial shares will be withheld, and the Participant must satisfy the tax obligation related to any such partial share using another permitted form of payment.

(h) Electronic Delivery. Any reference herein to a “written” agreement or document will include any agreement or document delivered electronically, filed publicly at www.sec.gov (or any successor website thereto) or posted on the Company’s intranet or other shared electronic medium controlled by the Company to which the Participant has access.

(i) Deferrals. To the extent permitted by applicable law, the Committee, in its sole discretion, may determine that the delivery of Common Stock, upon the exercise, vesting or settlement of all or a portion of any Award may be deferred and may establish programs and procedures for deferral elections to be made by Participants. Deferrals by Participants will be made in accordance with Section 409A of the Code. Consistent with Section 409A of the Code, the Committee may provide for distributions while a Participant is still an employee or otherwise providing services to the Company. The Committee is authorized to make deferrals of Awards and determine when, and in what annual percentages, Participants may receive payments, including lump sum payments, following the Participant’s termination of Continuous Service, and implement such other terms and conditions consistent with the provisions of the Plan and in accordance with applicable law.

(j) Compliance with Section 409A. Unless otherwise expressly provided for in an Award Agreement, the Plan and Award Agreements will be interpreted to the greatest extent possible in a manner that makes the Plan and the Awards granted hereunder exempt from Section 409A of the Code, and, to the extent not so exempt, in compliance with Section 409A of the Code. If the Committee determines that any Award granted hereunder is not exempt from and is therefore subject to Section 409A of the Code, the Award Agreement evidencing such Award will incorporate the terms and conditions necessary to avoid the consequences specified in Section 409A(a)(1) of the Code, and to the extent an Award Agreement is silent on terms necessary for compliance, such terms are hereby incorporated by reference into the Award Agreement, with the permitted distribution events and timing being the earlier of the date of termination of Continuous Service and the date of a Change in Control. Notwithstanding anything to the contrary in this Plan (and unless the Award Agreement specifically provides otherwise), if the shares of Common Stock are publicly traded, and if a Participant holding an

Award that constitutes “deferred compensation” under Section 409A of the Code is a “specified employee” for purposes of Section 409A of the Code, no distribution or payment of any amount that is due because of a “separation from service” (as defined in Section 409A of the Code without regard to alternative definitions thereunder) will be issued or paid before the date that is six (6) months following the date of such Participant’s “separation from service” or, if earlier, the date of the Participant’s death, unless such distribution or payment can be made in a manner that complies with Section 409A of the Code, and any amounts so deferred will be paid in a lump sum on the day after such six (6) month period elapses, with the balance paid thereafter on the original schedule.

(k) Clawback/Recovery.

(i) Awards granted under the Plan are subject to the terms and conditions of the Five9, Inc. Compensation Recoupment Policy (effective October 31, 2023, as may be further updated or amended from time to time) and any other clawback provisions, policy or policies (if any) as may be in effect from time to time, including any that specifically implement Section 10D of the Exchange Act, and any applicable rules or regulations promulgated thereunder (including applicable rules and regulations of any national securities exchange on which the shares of Common Stock at any point may be traded) (collectively, the “Clawback Policy”). In addition, the Committee may impose such other clawback, recovery or recoupment provisions in an Award Agreement as the Committee determines necessary or appropriate, including but not limited to a reacquisition right in respect of previously acquired shares of Common Stock or other cash or property upon the occurrence of Cause. The implementation of any clawback policy will not be deemed a triggering event for purposes of any definition of “good reason” for resignation or “constructive termination.” Further, by accepting any Award under the Plan, each Participant agrees (or has agreed) to fully cooperate with and assist the Company in connection with any of such Participant’s obligations to the Company pursuant to the Clawback Policy, and agrees (or has agreed) that the Company may enforce its rights under the Clawback Policy through any and all reasonable means permitted under applicable law as it deems necessary or desirable under the Clawback Policy, from and after the effective date thereof. Such cooperation and assistance shall include, but is not limited to, executing, completing and submitting any documentation necessary to facilitate the recovery or recoupment by the Company from such Participant of any such amounts, including from such Participants’ accounts or from any other compensation, to the extent permissible under Section 409A of the Code.

(ii) Otherwise, any Award Agreement (or any part thereof) may provide for the cancellation or forfeiture of an Award or the forfeiture and repayment to the Company of any gain or earnings related to an Award (or other provisions intended to have similar effects), including upon such terms and conditions as may be determined by the Committee in accordance with the Clawback Policy or any applicable laws, rules, regulations or requirements that impose mandatory clawback or recoupment requirements under the circumstances set forth in such laws, rules, regulations or requirements in effect from time to time (including as may operate to create additional rights for the Company with respect to such Awards and the recovery of amounts or benefits relating thereto).

(l) Whistleblower Protection. Nothing in the Plan, an Award Agreement or otherwise (a) limits the Participant’s right to any monetary award offered by a government-administered whistleblower award program for providing information directly to a government agency (including the Securities and Exchange Commission pursuant to Section 21F of the Exchange Act, the Dodd-Frank Wall Street Reform and Consumer Protection Act or The Sarbanes-Oxley Act of 2002) or (b) prevents the Participant from providing, without prior notice to the Company, information (including documents) to governmental authorities or agencies regarding possible legal violations or otherwise testifying or participating in any investigation or proceeding by any governmental authorities or agencies regarding possible legal violations (for purpose of clarification, the Participant is not prohibited from providing information (including documents) voluntarily to the Securities and Exchange Commission pursuant to Section 21F of the Exchange Act). The Company nonetheless asserts and does not waive its attorney-client privilege over any information protected by privilege.

(m) Rule 16b-3 Compliance. The Company intends that the Plan and any Awards comply in all respects with Rule 16b-3, and will be interpreted to give effect to such intention.

9.	CHANGES IN CAPITALIZATION; OTHER CORPORATE EVENTS.

(a) Capitalization Adjustments. In the event of a Capitalization Adjustment, the Committee will appropriately and proportionately adjust: (i) the class(es) and maximum number of securities subject to the Plan pursuant to Section 3(a), and (ii) the class(es) and number of securities and price per share of stock subject to outstanding Awards. The Committee will make such adjustments, and its determination will be final, binding and conclusive.

(b) Dissolution or Liquidation. Except as otherwise provided in the Award Agreement, in the event of a dissolution or liquidation of the Company, all outstanding Stock Awards (other than Stock Awards consisting of vested and outstanding shares of Common Stock not subject to a forfeiture condition or the Company’s right of repurchase) will terminate immediately prior to the completion of such dissolution or liquidation, and the shares of Common Stock subject to the Company’s repurchase rights or subject to a forfeiture condition may be repurchased or reacquired by the Company notwithstanding the fact that the holder of such Stock Award is providing Continuous Service. However, the Committee may, in its sole discretion, cause some or all Stock Awards to become fully vested, exercisable and/or no longer subject to repurchase or forfeiture (to the extent such Stock Awards have not previously expired or terminated) before the dissolution or liquidation is completed but contingent on its completion.

(c) Change in Control. The following provisions will apply to Awards in the event of a Change in Control unless otherwise provided in the Award Agreement or any other written agreement between the Company or any Affiliate and the Participant or unless otherwise expressly provided by the Committee at the time of grant.

On a Change in Control, the Committee will take one or more of the following actions with respect to Awards, contingent upon the closing or completion of the Change in Control:

(i) arrange for the surviving corporation or acquiring corporation (or the surviving or acquiring corporation’s parent company) to assume or continue the Award or to substitute a similar award for the Award (including, but not limited to, an award to acquire the same consideration paid to the stockholders of the Company pursuant to the Change in Control);

(ii) arrange for the assignment of any reacquisition or repurchase rights held by the Company in respect of Common Stock issued pursuant to the Award to the surviving corporation or acquiring corporation (or the surviving or acquiring corporation’s parent company);

(iii) accelerate the vesting, in whole or in part, of the Award (and, if applicable, the time at which the Award may be exercised) to a date prior to the effective time of such Change in Control as the Committee will determine (or, if the Committee will not determine such a date, to the date that is five days prior to the effective date of the Change in Control), with such Award terminating if not exercised (if applicable) at or prior to the effective time of the Change in Control;

(iv) arrange for the lapse, in whole or in part, of any reacquisition or repurchase rights held by the Company with respect to the Award on a date prior to the effective time of such Change in Control as the Committee will determine (or, if the Committee will not determine such a date, on the date that is five days prior to the effective date of the Change in Control); or

(v) cancel or arrange for the cancellation of the Award, to the extent not vested or not exercised prior to the effective time of the Change in Control, in exchange for a payment, in such form as may be determined by the Committee equal to the excess, if any, of (A) the value of the property the Participant would have received upon the exercise of the Award immediately prior to the effective time of the Change in Control, over (B) any exercise price payable by such holder in connection with such exercise. For clarity, this payment may be zero if the fair market value of the property is equal to or less than the exercise price.

For clarity, if the surviving corporation or acquiring corporation (or the surviving or acquiring corporation’s parent company) refuses to assume, continue, replace with new awards or otherwise substitute a new award for, an outstanding Award (including unvested outstanding shares), that Award will become fully vested as of immediately prior to the closing of the Change in Control.

The Committee need not take the same action or actions with respect to all Awards or portions thereof or with respect to all Participants. Only to the extent permitted under Code Section 409A, the Committee may provide that payments under this provision may be delayed to the same extent that payment of consideration to the holders of the Company’s Common Stock in connection with the Change in Control is delayed as a result of escrows, earn outs, holdbacks or other contingencies. An Award may be subject to additional acceleration of vesting and exercisability upon or after a Change in Control as provided in the Award Agreement for such Award or as may be provided in any other written agreement between the Company or any Affiliate and the Participant, but in the absence of such provision, no such acceleration will occur.

13.

DEFINITIONS.

(a) “Affiliate” means, at the time of determination, any “parent” or “subsidiary” of the Company as such terms are defined in Rule 405 of the Securities Act. The Committee will have the authority to determine the time or times at which “parent” or “subsidiary” status is determined within the foregoing definition.

(b) “Award” means a Stock Award.

(c) “Award Agreement” means a written agreement between the Company and a Participant evidencing the terms and conditions of an Award.

Notwithstanding the foregoing, the conversion of any convertible securities of the Company will not be treated as a Capitalization Adjustment.

(f) “Cause” means the occurrence of any one or more of the following: (i) the Participant’s commission of any felony involving fraud, dishonesty or moral turpitude; (ii) the Participant’s attempted commission of or participation in a fraud or act of dishonesty against the Company that results in (or might have reasonably resulted in) material harm to the business of the Company; (iii) the Participant’s intentional, material violation of any contract or agreement between the Participant and the Company or any statutory duty that the Participant owes to the Company; or (iv) the Participant’s conduct that constitutes gross insubordination, incompetence or habitual neglect of duties and that results in (or might have reasonably resulted in) material harm to the business of the Company. However, the action or conduct described in clauses (iii) and (iv) above will constitute “Cause” only if such action or conduct continues after the Company has provided the Participant with written notice thereof and thirty (30) days to cure the same.

(g) “Change in Control” means the occurrence, in a single transaction or in a series of related transactions, of any one or more of the following events:

(i) any Exchange Act Person becomes the Owner, directly or indirectly, of securities of the Company representing more than 50% of the combined voting power of the Company’s then outstanding securities other than by virtue of a merger, consolidation or similar transaction. A Change in Control will not be deemed to occur (A) on account of the acquisition of securities of the Company by an investor, any affiliate thereof or any other Exchange Act Person that acquires the Company’s securities in a transaction or series of related transactions the primary purpose of which is to obtain financing for the Company through the issuance of equity securities; or (B) solely because the level of Ownership held by any Exchange Act Person (the “Subject Person”) exceeds the designated percentage threshold of the outstanding voting securities as a result of a repurchase or other acquisition of voting securities by the Company reducing the number of shares outstanding, provided that if a Change in Control would occur (but for the operation of this sentence) as a result of the acquisition of voting securities by the Company, and after such share acquisition, the Subject Person becomes the Owner of any additional voting securities that, assuming the repurchase or other acquisition had not occurred, increases the percentage of the then outstanding voting securities Owned by the Subject Person over the designated percentage threshold, then a Change in Control will be deemed to occur;

(ii) there is consummated a merger, consolidation or similar transaction involving (directly or indirectly) the Company and, immediately after the consummation of such merger, consolidation or similar transaction, the stockholders of the Company immediately prior thereto do not Own, directly or indirectly, either (A) outstanding voting securities representing more than 50% of the combined outstanding voting power of the surviving Entity in such merger, consolidation or similar transaction or (B) more than 50% of the combined outstanding voting power of the parent of the surviving Entity in such merger, consolidation or similar transaction, in each case in substantially the same proportions as their Ownership of the outstanding voting securities of the Company immediately prior to such transaction;

(iii) there is consummated a sale, lease, exclusive license or other disposition of all or substantially all of the consolidated assets of the Company and its Subsidiaries, other than a sale, lease, license or other disposition of all or substantially all of the consolidated assets of the Company and its Subsidiaries to an Entity, more than 50% of the combined voting power of the voting securities of which are Owned by stockholders of the Company in substantially the same proportions as their Ownership of the outstanding voting securities of the Company immediately prior to such sale, lease, license or other disposition; or

(iv) individuals who, on the Effective Date, are members of the Board (the “Incumbent Board”) cease for any reason to constitute at least a majority of the members of the Board. However, if the appointment or election (or nomination for election) of any new Board member was approved or recommended by a majority vote of the members of the Incumbent Board then still in office, such new member will, for purposes of this Plan, be considered as a member of the Incumbent Board.

For purposes of determining voting power under the term Change in Control, voting power shall be calculated by assuming the conversion of all equity securities convertible (immediately or at some future time) into shares entitled to vote, but not assuming the exercise of any warrant or right to subscribe to or purchase those shares. In addition, the term Change in Control will not include (A) a sale of assets, merger or other transaction effected exclusively for the purpose of changing the domicile of the Company, or (B) a change in the voting power of any one or more stockholders as a result of the conversion of any class of the Company’s securities into another class of the Company’s securities having a different number of votes per share pursuant to the conversion provisions set forth in the Company’s Amended and Restated Certificate of Incorporation.

The definition of Change in Control (or any analogous term) in an individual written agreement between the Company or any Affiliate and the Participant will supersede the foregoing definition with respect to Awards subject to such agreement. If required for compliance with Section 409A of the Code, in no event will a Change in Control be deemed to have occurred if such transaction is not also a “change in the ownership or effective control of” the Company or “a change in the ownership of a substantial portion of the assets of” the Company as determined under Treasury Regulation Section 1.409A-3(i)(5) (without regard to any alternative definition thereunder). The Board may, in its sole discretion and without a Participant’s consent, amend the definition of “Change in Control” to conform to the definition of “Change in Control” under Section 409A of the Code, and the regulations thereunder.

(h) “Code” means the Internal Revenue Code of 1986, as amended, including any applicable regulations and guidance thereunder.

(i) “Committee” means the Compensation Committee of the Board or a group of Directors consisting solely of a majority of Directors who meet the requirements for independence under the Listing Rules.

(l) “Consultant” means any person, including an advisor, who is (i) engaged by the Company or an Affiliate to render consulting or advisory services and is compensated for such services, or (ii) serving as a member of the board of directors of an Affiliate and is compensated for such services. However, service solely as a Director, or payment of a fee for such service, will not cause a Director to be considered a “Consultant” for purposes of the Plan. However, a person may be treated as a Consultant under this Plan only if a Form S-8 Registration Statement under the Securities Act is available to register either the offer or the sale of the Company’s securities to such person.

(m) “Continuous Service” means that the Participant’s service with the Company or an Affiliate is not interrupted or terminated. A change in the capacity in which the Participant renders service to the Company or an Affiliate or a change in the entity for which the Participant renders such service, provided that there is no interruption or termination of the Participant’s service with the Company or an Affiliate, will not terminate a Participant’s Continuous Service. If the Entity for which a Participant is rendering services ceases to qualify as an Affiliate, such Participant’s Continuous Service will be considered to have terminated on the date such Entity ceases to qualify as an Affiliate. To the extent permitted by law, the Committee or the chief executive officer of the Company, in that party’s sole discretion, may determine whether Continuous Service will be considered interrupted in the case of (i) any leave of absence approved by the Committee or chief executive officer, including sick leave, military leave or any other personal leave, or (ii) transfers between the Company, an Affiliate, or their successors. A leave of absence will be treated as Continuous Service for purposes of vesting in an Award only to such extent provided in the Company’s leave of absence policy, in the written terms of any leave of absence agreement applicable to the Participant, or as otherwise required by law. In addition, if required for exemption from or compliance with Section 409A of the Code, the determination of Continuous Service will be made, and such term will be construed, in a manner that is consistent with the definition of “separation from service” as defined under Treasury Regulation Section 1.409A-1(h) (without regard to any alternative definition thereunder).

(n) “Director” means a member of the Board.

(o) “Disability” means, with respect to a Participant, the inability of such Participant to engage in any substantial gainful activity by reason of any medically determinable physical or mental impairment that can be expected to result in death or that has lasted or can be expected to last for a continuous period of not less than 12 months, as provided in Sections 22(e)(3) and 409A(a)(2)(c)(i) of the Code, and will be determined on the basis of such medical evidence as the Company deems warranted under the circumstances.

(p) “Effective Date” means June 5, 2026.

(q) “Employee” means any person employed by the Company or an Affiliate. However, service solely as a Director, or payment of a fee for such services, will not cause a Director to be considered an “Employee” for purposes of the Plan.

(r) “Entity” means a corporation, partnership, limited liability company or other entity.

(s) “Exchange Act” means the Securities Exchange Act of 1934, as amended, and the rules and regulations promulgated thereunder.

(u) “Fair Market Value” means, as of any date, the value of the Common Stock determined as follows:

(i) If the Common Stock is listed on any established stock exchange or traded on any established market, the Fair Market Value of a share of Common Stock will be, unless otherwise determined by the Committee, the closing sales price for such stock as quoted on such exchange or market (or the exchange or market with the greatest volume of trading in the Common Stock) on the date of determination, as reported in a source the Committee deems reliable.

(ii) Unless otherwise provided by the Committee, if there is no closing sales price for the Common Stock on the date of determination, then the Fair Market Value will be the closing selling price on the last preceding date for which such quotation exists.

(iii) In the absence of such markets for the Common Stock, the Fair Market Value will be determined by the Committee in good faith and in a manner that complies with Sections 409A and 422 of the Code.

In determining the value of a share for purposes of tax reporting on the exercise, issuance or transfer of shares subject to Awards, fair market value may be calculated using the definition of Fair Market Value, the actual sales price in the transaction at issue (e.g., “sell to cover”), or such other value determined by the Company’s General Counsel in good faith in a manner that complies with applicable tax laws.

(v) “Listing Rules” means the Nasdaq Stock Market LLC Listing Rules.

(w) “Officer” means a person who is an officer of the Company within the meaning of Section 16 of the Exchange Act.

(z) “Own,” “Owned,” “Owner,” “Ownership” A person or Entity will be deemed to “Own,” to have “Owned,” to be the “Owner” of, or to have acquired “Ownership” of securities if such person or Entity, directly or indirectly, through any contract, arrangement, understanding, relationship or otherwise, has or shares voting power, which includes the power to vote or to direct the voting, with respect to such securities.

(aa) “Participant” means a person to whom an Award is granted pursuant to the Plan or, if applicable, such other person who holds an outstanding Stock Award.

(bb) “Performance Goals” means, for a Performance Period, the one or more goals established by the Committee for the Performance Period. Performance Goals may be based on a Company-wide basis, with respect to one or more business units, divisions, Affiliates, or business segments, and in either absolute terms or relative to the performance of one or more comparable companies or the performance of one or more relevant indices. If the Committee determines that a change in the business, operations, corporate structure or capital structure of the Company (or its business units, divisions, Affiliates, or business segments) or the manner in which it conducts its business, or other events or circumstances render the Performance Goals unsuitable, the Committee may in its discretion modify such Performance Goals or the targets or actual levels of achievement regarding the Performance Goals in whole or in part, as the Committee deems appropriate and equitable.

(cc) “Performance Period” means the period of time selected by the Committee over which the attainment of one or more Performance Goals will be measured for the purpose of determining a Participant’s right to and the payment of a Stock Award. Performance Periods may be of varying and overlapping duration, at the sole discretion of the Committee.
