Role of Board in Risk Oversight

One of the key functions of the Board is informed oversight of the Company’s risk management process. The Board does not have a standing risk management committee, but rather administers this oversight function directly through the Board as a whole, as well as through the Board’s various standing committees that address risks inherent in their respective areas of oversight. Specifically, the audit committee of the Board is responsible for overseeing the management of risks associated with the Company’s financial reporting, accounting, and auditing matters, and the compensation committee of the Board oversees the management of risks associated with the Company’s compensation policies and programs.

Cooper, the Chief Executive Officer and President of enGene, (ii) Philip Astley-Sparke, (iii) Gerald Brunk, (iv) Dr. Richard Glickman, (v) Dr. William Grossman, (vi) Paul Hastings, (vii) Michael Heffernan, (viii) Wouter Joustra and (ix) Lota Zoth. Under the Business Corporations Act (British Columbia) (“BCBCA”), a director may be removed with or without cause by a resolution passed by a special majority of the votes cast by shareholders present in person or by proxy at a meeting and who are entitled to vote.

Staggered Board Provisions

Our articles of incorporation and notice of articles (together, the “Articles”) provide for a staggered board of directors consisting of three groups of directors with directors serving staggered three-year terms.

At every annual general meeting and in every unanimous shareholder resolution in lieu thereof, all of the directors whose terms expire cease to hold office immediately before the election or appointment of directors, but are eligible for re-election or re-appointment. The shareholders entitled to vote at the annual general meeting for the election of directors may elect, or in a unanimous resolution appoint, the number of directors required to fill any vacancies created. The directors will hold office for the applicable terms contemplated in the staggered board provisions. Upon the resignation of a director, the remaining directors may fill the casual vacancy resulting from such resignation for the remainder of the unexpired term.

The terms of office for each of our directors are as follows:

Upon the expiry of the initial terms described above, directors will be elected pursuant to Article 14.2 of the Articles to hold office for three-year terms expiring on the third annual general meeting following their election.

Replacement or Removal of Directors

Under the BCBCA and the Articles, a director may be removed with or without cause by a special resolution passed by a special majority (being two-thirds) of the votes cast by shareholders present in person or by proxy at a duly convened meeting and who are entitled to vote.

To the extent directors are elected or appointed to fill casual vacancies or vacancies arising from the removal of directors, in both instances whether by shareholders or directors, the directors shall hold office until the remainder of the unexpired portion of the term of the departed director that was replaced.

Under the Articles, the number of directors of enGene must be set at a minimum of three (3). The directors will be authorized to determine the actual number of directors to be elected from time to time.

Director Term Limits and Other Mechanisms of Board Renewal

enGene’s Board has not adopted director term limits or other automatic mechanisms of board renewal. Rather than adopting formal term limits, mandatory age-related retirement policies and other mechanisms of board renewal, the nominating and corporate governance committee of the Board has developed a skills and competencies matrix for enGene’s Board as a whole and for individual directors. The nominating and corporate governance committee has developed and oversees a process for the assessment of the Board, each committee and each director regarding their or its effectiveness and contribution, and report evaluation results to the Board on a regular basis.

enGene does not have a formal policy nor measurable objectives (such as a target) regarding board diversity or for the representation of women on their board of directors, management team or executive officers. enGene expects that its priority in the selection of enGene’s Board members will be to identify members who will further the interests of its shareholders through their established record of professional accomplishment, the ability to contribute positively to the collaborative culture among board members, and knowledge of enGene’s business and understanding of the competitive landscape.

Independence of the Members of the Board of Directors

Director Independence

Applicable Nasdaq rules require a majority of a listed company’s board of directors to be comprised of independent directors. Under applicable Nasdaq rules, a director will only qualify as an “independent director” if, in the opinion of the listed company’s board of directors, that person does not have a relationship that would interfere with the exercise of independent judgment in carrying out the responsibilities of a director. Under National Instrument 58-101 – Disclosure of Corporate Governance Practices (“NI 58-101”) implemented by the Canadian Securities Administrators, a director is considered to be independent if that person is independent within the meaning of National Instrument 52-110 — Audit Committees (“NI 52-110”). Pursuant to NI 52-110, an independent director is a director who is free from any direct or indirect relationship which could, in the view of enGene’s Board of Directors, be reasonably expected to interfere with a director’s independent judgment.

enGene’s Board has determined that (i) each of Philip Astley-Sparke, Gerald Brunk, Richard Glickman, William Grossman, Paul Hastings, Michael Heffernan, Wouter Joustra and Lota Zoth is an independent director under applicable Nasdaq rules and pursuant to NI 52-110 and (ii) each of Philip Astley-Sparke, Gerald Brunk, Richard Glickman, William Grossman, Paul Hastings, Michael Heffernan and Lota Zoth are independent under the heightened independence standards of NI 52-110, the SEC and Nasdaq rules for audit committee independence.

The independent directors of enGene’s Board hold regularly scheduled meetings at which non-independent directors and members of management are not in attendance.

Mandate of the Board of Directors

enGene’s Board is responsible for the stewardship of the Company and providing oversight as to the management of enGene and its affairs, including providing guidance and strategic oversight to management. enGene’s Board has adopted a formal mandate that includes the following:

Meetings of Directors

enGene’s board of directors may meet together for the conduct of business, adjourn and otherwise regulate their meetings as they think fit, and meetings of the directors held at regular intervals may be held at the place, at the time and on the notice, if any, as the directors may from time to time determine. The independent members of enGene’s board of directors will also meet, as required, without the non-independent directors and members of management before or after each regularly scheduled board meeting.

A director who has a material interest in a matter before the Board or any committee on which they serve is required to disclose such interest as soon as the director becomes aware of it. In situations where a director has a material interest in a matter to be considered by the Board or any committee on which they serve, such director may be required to absent themselves from the meeting while discussions and voting with respect to the matter are taking place. Directors will also be required to comply with the relevant provisions of the BCBCA regarding conflicts of interest.

The frequency of meetings of the Board and the nature of agenda items may change from year to year depending upon the Company’s activities, however the Board generally meets at least quarterly, and at each meeting there is a review of enGene’s business. The Board facilitates its exercise of independent supervision over the Company’s management by holding regular meetings of the Board where the directors discuss significant corporate activities and plans, both with and without members of the Company’s management being in attendance.

Board Committees

The standing committees of the Board consist of an audit committee, a compensation committee, a nominating and corporate governance committee and a research and development committee. The Board may from time to time establish other committees.

Our chief executive officer and other executive officers will regularly report to the non-executive directors and the audit, the compensation, the nominating and corporate governance and the research and development committees to ensure effective and efficient oversight of our activities and to assist in proper risk management and the ongoing evaluation of management controls. We believe that the leadership structure of the board of directors provides appropriate risk oversight of our activities.

Audit Committee

enGene has established an audit committee comprised of independent directors as required by applicable SEC, Nasdaq rules and NI 52-110. At least one member of the audit committee will qualify as an “audit committee financial expert”, as such term is defined the rules and regulations established by the SEC, and all members of the audit committee are “financially literate”, as such term is defined in NI 52-110 (except as may be permitted by NI 52-110). The principal purpose of enGene’s audit committee is to assist the Board in its oversight of:

The Board has established a written charter setting forth the purpose, composition, authority and responsibility of the audit committee, consistent with the rules of the Nasdaq, the SEC and NI 52-110.

enGene’s audit committee has access to all of the Company’s books, records, facilities and personnel and may request any information about enGene as it may deem appropriate. It also has the authority in its sole discretion and at enGene’s expense, to retain and set the compensation of outside legal, accounting or other advisors as necessary to assist in the performance of its duties and responsibilities.

The audit committee currently consists of Lota Zoth (Chair), Philip Astley-Sparke and Michael Heffernan. The Board has determined that Ms. Zoth qualifies as an audit committee financial expert.

Compensation Committee

Under SEC and the Nasdaq rules, there are heightened independence standards for members of the compensation committee. enGene’s compensation committee members meet this heightened standard and are also independent for purposes of NI 58-101. The functions of the compensation committee include:

The Board has established a written charter that sets forth the purpose, composition, authority and responsibility of the compensation committee consistent with the rules of the Nasdaq, the SEC and the guidance of the Canadian Securities Administrators.

The compensation committee currently consists of Gerald Brunk (Chair), Paul Hastings, Michael Heffernan and Wouter Joustra.

Nominating and Corporate Governance Committee

The members of the nominating and governance committee are independent for purposes of NI 58-101.

enGene’s Board has established a written charter that sets forth the purpose, composition, authority and responsibility of enGene’s nominating and corporate governance committee. The nominating and corporate governance committee’s purpose is to assist the Board in:

In identifying new candidates for enGene’s Board, the nominating and corporate governance committee will consider what competencies and skills the Board, as a whole, should possess and assess what competencies and skills each existing director possesses, considering enGene’s Board as a group, and the personality and other qualities of each director, as these may ultimately determine the boardroom dynamic.

It is the responsibility of the nominating and corporate governance committee to regularly evaluate the overall efficiency of enGene’s Board and its Chair and all board committees and their chairs. As part of its mandate, the nominating and corporate governance committee will conduct the process for the assessment of enGene’s Board, each committee and each director regarding their or its effectiveness and contribution, and report evaluation results to the Board on a regular basis.

The nominating and corporate governance committee currently consists of Richard Glickman (Chair), Philip Astley-Sparke, Paul Hastings and Lota Zoth.

Research and Development Committee

enGene’s Board has established a written charter that sets forth the purpose, composition, authority and responsibility of enGene’s research and development committee. The research and development committee’s purpose is to assist the Board by:

The research and development committee currently consists of William Grossman (Chair), Gerald Brunk and Richard Glickman.

Code of Business Conduct and Ethics

enGene has established a code of business conduct and ethics (the “Code of Conduct”) applicable to all of enGene’s directors, officers and employees, including its Chief Executive Officer, Chief Financial Officer, controller or principal accounting officer, or other persons performing similar functions, which will be a “code of ethics” as defined in Item 406(b) of Regulation S-K promulgated by the SEC and which will be a “code” under NI 58-101. The Code of Conduct sets out the fundamental values and standards of behavior that are expected from enGene’s directors, officers, employees, consultants and contractors with respect to all aspects of its business. The objective of the Code of Conduct is to provide written standards designed to promote integrity and deter wrongdoing.

The full text of the Code of Conduct is posted on enGene’s website at www.engene.com. The written Code of Conduct is filed with the Canadian securities regulatory authorities on SEDAR+ at www.sedarplus.ca. Information contained on, or that can be accessed through, enGene’s website does not constitute a part of this Amendment No. 1 and is not incorporated by reference herein. If enGene makes any amendment to the Code of Conduct or grants any waivers, including any implicit waiver, from a provision of the code of ethics included within the Code of Conduct, enGene will disclose the nature of such amendment or waiver on its website to the extent required by the rules and regulations of the SEC and the Canadian Securities Administrators. enGene intends to satisfy the disclosure requirement under Item 5.05 of Form 8-K regarding an amendment to, or a waiver from, a provision of its code of ethics that applies to its principal executive officer, principal financial officer, principal accounting officer or controller or persons performing similar functions, by posting such information on enGene’s internet website.

Monitoring Compliance with the Code of Conduct

enGene’s nominating and corporate governance committee is responsible for reviewing and evaluating the Code of Conduct at least annually and recommending any necessary or appropriate changes to the Board for consideration. Additionally, the nominating and corporate governance committee assists enGene’s Board with the monitoring of compliance with the Code of Conduct, and will be responsible for considering any waivers of the Code of Conduct (other than waivers applicable to members of the nominating and corporate governance committee, which shall be considered by the audit committee, or waivers applicable to enGene’s directors or executive officers, which shall be subject to review by the Board as a whole).

Insider Trading Policy

We are committed to promoting high standards of ethical business conduct and compliance with applicable laws, rules and regulations. As part of this commitment, we have adopted and maintain our Insider Trading Policy which we believe is reasonably designed to promote compliance with insider trading laws, rules and regulations, and the exchange listing standards applicable to us. Our Insider Trading Policy was filed as Exhibit 19 to the Original Form 10-K filed with the SEC on December 22, 2025. Our Insider Trading Policy governs the purchase, sale and/or other disposition of our securities and applies to all directors, officers, and employees of enGene and its subsidiaries as well as consultants that we may designate from time to time. Pursuant to the Company’s Insider Trading Policy, every Company insider is prohibited from speculative or indirect trading in Company securities – such as short sales, trading in puts, calls or options – or similar rights or obligations to buy or sell Company securities, or the purchase of Company securities with the intention of quickly reselling them. In addition, Company insiders may not buy Company securities on margin, and are prohibited from purchasing financial instruments designed to hedge or offset a decrease in the market value of Company securities. Insiders are strongly discouraged from using Company securities as collateral for loans or in margin accounts. In addition, our policy prohibits Company insiders from purchasing or selling our securities while in possession of material, non-public information, or otherwise using such information for their personal benefit or to make recommendations or express opinions to another person regarding trading our securities. In addition, we maintain a quarterly black-out window and will impose special blackout periods during which applicable individuals may not trade.

Company insiders are permitted to enter into trading plans that are intended to comply with the requirements of Exchange Act Rule 10b5-1 and comparable Canadian securities law requirements so they may make predetermined trades of our securities.

Corporate Governance Guidelines

The Rule 5600 Series of the Nasdaq Listing Rules generally requires that a listed company’s constituting documents provide for a quorum for any meeting of the holders of the company’s Common Shares that is greater than 33-1/3% of the outstanding shares of the company’s Common Shares that provide voting rights. enGene’s Articles provide that a quorum of shareholders is the holders of at least 33-1/3% of the shares entitled to vote at the meeting, present in person or represented by proxy, and at least two persons entitled to vote at the meeting, present in person or represented by proxy.

Except as stated above, enGene complies with the rules generally applicable to U.S. domestic companies listed on the Nasdaq.

The Canadian Securities Administrators has issued corporate governance guidelines pursuant to National Policy 58-201 — Corporate Governance Guidelines (the “Corporate Governance Guidelines”), together with certain related disclosure requirements pursuant to NI 58-101. The Corporate Governance Guidelines are recommended as guidelines for issuers to consider in developing their own corporate governance practices. enGene recognizes that good corporate governance plays an important role in its overall success and in enhancing shareholder value and, accordingly, enGene has adopted certain corporate governance policies and practices which reflect its consideration of the recommended Corporate Governance Guidelines.

The disclosure herein describes enGene’s approach to corporate governance in relation to the Corporate Governance Guidelines.

Delinquent Section 16(a) Reports

Under Section 16(a) of the Exchange Act, directors, executive officers and beneficial owners of 10% or more of our common shares (collectively, “reporting persons”), are required to report to the SEC on a timely basis the initiation of their status as a reporting person and any changes with respect to their beneficial ownership of our common shares. Based solely on our review of copies of reports filed pursuant to Section 16(a), or written representations from reporting persons, we believe that during the fiscal year ended October 31, 2025, all Section 16(a) filing requirements applicable to the reporting persons were timely met, with the exception of one late Form 4 filing by Matthew Boyd caused by a delay in obtaining his EDGAR filer codes.

Item 11. Executive Compensation.

Executive Compensation Overview

The following discussion contains forward-looking statements that are based on our current plans, considerations, expectations and determinations regarding future compensation programs. The actual amount and form of compensation and the compensation policies and practices that we adopt in the future may differ materially from currently planned programs as summarized in this discussion.

The compensation provided to our named executive officers for the fiscal years ended October 31, 2025 and 2024 (“fiscal 2025” and “fiscal 2024,” respectively) is detailed in the Summary Compensation Table and accompanying footnotes and narrative that follow this section.

For fiscal 2025, the “named executive officers” and their positions were as follows:

Summary Compensation Table

The following table presents information regarding the total compensation awarded to, earned by, and paid to our named executive officers for services rendered to us in all capacities for the fiscal years ended October 31, 2025 and 2024.

Narrative to Summary Compensation Table

Base Salaries

We use base salaries to recognize the experience, skills, knowledge and responsibilities required of all our employees, including our named executive officers. Base salaries are reviewed annually, typically in connection with our annual performance review process, and adjusted from time to time to realign salaries with market levels after taking into account individual responsibilities, performance and experience. For the fiscal year ended October 31, 2025, the annualized base salary for each of Mr. Cooper, Mr. Daws and Dr. Sweiti, was $700,000, $484,000, and $525,000, respectively.

Cash Incentive Compensation

We seek to motivate and reward our executives for achievements relative to our corporate goals and expectations. Cash bonuses are earned by our executives based on the achievement of overall company performance criteria over the course of each calendar year (not fiscal year). Accordingly, amounts for each of the Company’s named executive officers in the “Nonequity incentive plan compensation” column for fiscal 2025 and fiscal 2024 were awarded as a result of the achievement of certain performance measures over calendar years 2025 and 2024. The company performance criteria for calendar years 2025 and 2024 included operational goals in the areas of the clinical development of detalimogene voraplasmid, or detalimogene, the manufacturing of detalimogene, potential indications for detalimogene, preparations for a potential biologics license application submission, financial discipline and building awareness. For 2025, the compensation committee determined that overall corporate performance was achieved based on an assessment of the pre-established corporate goals and determined to grant cash incentive compensation awards to our named executive officers (other than Dr. Sweiti) for 2025 in the amounts of $483,000 and $222,640 to Mr. Cooper and Mr. Daws, respectively. For Dr. Sweiti, his employment agreement provides that in lieu of any annual cash incentive compensation for 2025, he is entitled to a one-time cash bonus of $50,000, to be paid in the second regular payroll cycle in February 2026, subject to his continued employment in good standing through the payment date. See “— Employment Arrangements with our Named Executive Officers — Dr. Hussein Sweiti.” However, as a result of the performance of the company against the pre-established corporate goals during 2025, in January 2026, the compensation committee determined to grant a discretionary bonus award to Dr. Sweiti in the amount of $12,195.

Equity Compensation

Although we do not have a formal policy with respect to the grant of equity incentive awards to our executive officers, we believe that equity grants provide our executive officers with a strong link to our long-term performance, create an ownership culture and help to align the interests of our executive officers and our shareholders. In addition, we believe that equity grants with a time-based vesting feature promote executive retention because this feature incentivizes our executive officers to remain in our employment during the vesting period. We have used stock options to compensate our executive officers in the form of initial grants in connection with the executive officer’s appointment to his or her position, which are typically negotiated in connection with their hiring, and generally on an annual basis thereafter. In connection with the hiring of Dr. Sweiti in September 2025, we awarded him a stock option for Common Shares in the amount of 600,000. In connection with our annual compensation process, in January 2025, we awarded stock options for Common Shares in the amounts of 850,000 and 280,000 to Messrs. Cooper and Daws, respectively. The new hire stock options we grant to executives have a 10-year term and vest over four years, with 25% of the underlying shares vesting on the one-year anniversary of the grant date or employment commencement date, as applicable, and the remainder vesting in equal amounts monthly for three years thereafter, subject to the executive officer’s continued service as an employee of, or other service provider to, the Company through the applicable vesting dates. The stock options we grant to executives on an annual basis have a 10-year term and vest in equal amounts monthly over four years, subject to the executive officer’s continued service as an employee of, or other service provider to, the Company through the applicable vesting dates.

Outstanding Equity Awards at 2025 Fiscal Year-End

The following table sets forth information concerning outstanding equity awards held by each of our named executive officers as of October 31, 2025.

Employee Benefit and Equity Compensation Plans

Summary of the Equity Plans

For the fiscal years ended October 31, 2024 and 2025, executive compensation was under the enGene Holdings Inc. Amended and Restated 2023 Incentive Equity Plan (the “Incentive Equity Plan”). The following is a summary of the Incentive Equity Plan.

Type of Awards

The Incentive Equity Plan provides for the issuance of stock options (including non-statutory stock options and incentive stock options), stock appreciation rights (“SARs”), restricted shares, restricted share units and other share-based awards to employees, non-employee directors, and certain consultants and advisors of enGene or its subsidiaries.

Administration

The Incentive Equity Plan is administered by the compensation committee of the Board or another committee appointed by the Board to administer the Incentive Equity Plan (the “Committee”); provided that any grants to members of the Board must be authorized by a majority of the Board (counting all the Board members for purposes of a quorum, but only non-interested Board members for purposes of such majority approval). The Committee (if other than the full Board) must consist of directors who are “non-employee

directors” as defined under Rule 16b-3 promulgated under the Exchange Act and “independent directors,” as determined in accordance with the independence standards established by the stock exchange on which the Common Shares is at the time primarily traded. The Committee may delegate authority under the Incentive Equity Plan to one or more subcommittees as it deems appropriate. Subject to compliance with applicable law and stock exchange requirements, so long as the Chief Executive Officer is also a director on the Board, the Committee may delegate all or part of its authority to the Chief Executive Officer (or if there is none then appointed, the President), as it deems appropriate, with respect to grants to employees or consultants who are not executive officers under Section 16 of the Exchange Act.

Shares Subject to the Incentive Equity Plan

As of February 17, 2026, the number of Common Shares subject to the Incentive Equity Plan was 11,922,732, inclusive of 2,888,237 Common Shares enGene is authorized to issue under the plan, plus 8,761,570 Common Shares that are subject to outstanding grants and outstanding restricted stock units of 272,925 Common Shares. The Incentive Equity Plan contains an evergreen provision, pursuant to which, commencing with the first business day of each calendar year, the aggregate number of Common Shares that may be issued or transferred under the Incentive Equity Plan will be increased by a number of Common Shares equal to the lesser of (x) 5% of the issued and outstanding Common Shares, or (y) such lesser number of shares as may be determined by the Committee.

If any options or SARs granted under the Incentive Equity Plan (including options or SARs granted under the prior enGene Inc. Plans) expire or are canceled, forfeited, exchanged, or surrendered without having been exercised, or if any share awards, share units, or other share-based awards granted under the Incentive Equity Plan (including options or SARs granted under the prior enGene Inc. Plans) are forfeited, terminated, or otherwise not paid in full, the Common Shares subject to such awards will again be available for purposes of the Incentive Equity Plan. If Common Shares are surrendered in payment of the exercise price of an option, the number of Common Shares available for issuance under the Incentive Equity Plan will be reduced only by the net number of shares actually issued by the Company upon such exercise and not by the gross number of shares as to which such option is exercised. Upon the exercise of any SAR under the Incentive Equity Plan, the number of Common Shares available for issuance will be reduced only by the net number of shares actually issued by the Company upon such exercise.

If Common Shares are withheld by the Company in satisfaction of the withholding taxes incurred in connection with the issuance, vesting or exercise of any grant or the issuance of Common Shares under the Incentive Equity Plan, the number of Common Shares available for issuance will be reduced by the net number of shares issued, vested, or exercised under such grant, calculated in each instance after payment of such share withholding. If any awards are paid in cash, and not in Common Shares, any Common Shares subject to such awards will also be available for future awards. If the Company repurchases its Common Shares on the open market with the proceeds from the exercise price the Company receives from options, the repurchased shares will not be available for issuance under the Incentive Equity Plan.

Individual Limits for Non-Employee Directors

The maximum aggregate grant date value of Common Shares granted to any non-employee director in any one calendar year, taken together with any cash fees earned by such non-employee director for services rendered during the calendar year, shall not exceed $500,000 in total value; provided, however, that with respect to the year during which a non-employee director is first appointed or elected to the Board, the maximum aggregate grant date value of Common Shares granted to such non-employee director, taken together with any cash fees earned by such non-employee director for services rendered during such period, shall not exceed $750,000 in total value during the initial annual period.

Adjustments

In connection with stock splits, stock dividends, recapitalizations, and certain other events affecting Common Shares, the Committee will make adjustments as it deems appropriate in: the maximum number of Common Shares reserved for issuance as grants; the maximum amount of awards that may be granted to any individual non-employee director in any year; the number and kind of shares covered by outstanding grants; the number and kind of shares that may be issued under the Incentive Equity Plan; the price per share or market value of any outstanding grants; the exercise price of options; the base amount of SARs; and the performance goals or other terms and conditions as the Committee deems appropriate.

Eligibility and Vesting

All of the employees and non-employee directors of enGene are eligible to receive grants under the Incentive Equity Plan. In addition, consultants who perform certain services for enGene may receive grants under the Incentive Equity Plan. The Committee will (i) select the employees, non-employee directors, and consultants to receive grants and (ii) determine the number of Common Shares subject to a particular grant and the vesting and exercisability terms of awards granted under the Incentive Equity Plan.

Options

Under the Incentive Equity Plan, the Committee will determine the exercise price of the options granted and may grant options to purchase Common Shares in such amounts as it determines. The Committee may grant options that are intended to qualify as incentive stock options under Section 422 of the Code, or non-qualified stock options, which are not intended to so qualify. Incentive stock options may only be granted to employees. Anyone eligible to participate in the Incentive Equity Plan may receive a grant of non-qualified stock options. The exercise price of a stock option granted under the Incentive Equity Plan cannot be less than the fair market value of a Common Share on the date the option is granted. If an incentive stock option is granted to a 10% shareholder of the total combined voting power of all classes of enGene securities, the exercise price cannot be less than 110% of the fair market value of a Common Share on the date the option is granted.

The exercise price for any option is generally payable in cash. In certain circumstances as permitted by the Committee, the exercise price may be paid: by the surrender of Common Shares with an aggregate fair market value, on the date the option is exercised, equal to the exercise price; by payment through a broker in accordance with procedures established by the Federal Reserve Board; solely with respect to non-qualified stock options, by Common Shares subject to the exercisable option that have a fair market value on the date of exercise equal to the aggregate exercise price; or by such other method as the Committee approves.

The term of an option cannot exceed 10 years from the date of grant, except that if an incentive stock option is granted to a 10% shareholder of the total combined voting power of all class of enGene securities, the term cannot exceed five years from the date of grant. In the event that on the last day of the term of a non-qualified stock option, the exercise is prohibited by applicable law, including a prohibition on purchases or sales of Common Shares under the enGene insider trading policy, or pursuant to any restrictions on transfer imposed by the Committee, the term of the non-qualified option will be extended for a period of 30 days following the end of the legal prohibition, or until the expiration of such restrictions on transfer, unless the Committee determines otherwise.

Except as provided in the grant instrument, an option may only be exercised while a participant is employed by or providing service to us. The Committee will determine in the grant instrument under what circumstances and during what time periods a participant may exercise an option after termination of employment.

Share Awards

Under the Incentive Equity Plan, the Committee may grant share awards. A share award is an award of Common Shares that may be subject to restrictions as the Committee determines. The restrictions, if any, may lapse over a specified period of employment or based on the satisfaction of pre-established criteria, in installments or otherwise, as the Committee may determine, including, but not limited to, restrictions based on the achievement of performance goals. Except to the extent restricted under the grant instrument relating to the share award, a participant will have all of the rights of a shareholder as to those shares, including the right to vote and the right to receive dividends or distributions on the shares. Dividends with respect to share awards that vest based on performance shall vest if and to the extent that the underlying share award vests, as determined by the Committee. All unvested share awards are forfeited if the participant’s employment or service is terminated for any reason, unless the Committee determines otherwise.

Share Units

Under the Incentive Equity Plan, the Committee may grant share units to anyone eligible to participate in the Incentive Equity Plan. Share units represent hypothetical Common Shares. Share units become payable on terms and conditions determined by the Committee, including specified performance goals, and will be payable in cash, Common Shares, or a combination thereof, as determined by the Committee. All unvested share units are forfeited if the participant’s employment or service is terminated for any reason, unless the Committee determines otherwise.

Stock Appreciation Rights

Under the Incentive Equity Plan, the Committee may grant SARs, which may be granted separately or in tandem with any option. SARs granted in tandem with a non-qualified stock option may be granted either at the time the non-qualified stock option is granted or any time thereafter while the option remains outstanding. SARs granted in tandem with an incentive stock option may be granted only at the time the grant of the incentive stock option is made. The Committee will establish the base amount of the SAR at the time the SAR is granted, which will be equal to or greater than the fair market value of a Common Share as of the date of grant.

If a SAR is granted in tandem with an option, the number of SARs that are exercisable during a specified period will not exceed the number of Common Shares that the participant may purchase upon exercising the related option during such period. Upon exercising the related option, the related SARs will terminate, and upon the exercise of a SAR, the related option will terminate to the extent of an equal number of Common Shares. Generally, SARs may only be exercised while the participant is employed by, or providing services to, us. When a participant exercises a SAR, the participant will receive the excess of the fair market value of the underlying Common Shares over the base amount of the SAR. The appreciation of a SAR will be paid in Common Shares, cash, or both.

The term of a SAR cannot exceed 10 years from the date of grant. In the event that on the last day of the term of a SAR, the exercise is prohibited by applicable law, including a prohibition on purchases or sales of Common Shares under our Insider Trading Policy, or pursuant to any restrictions on transfer imposed by the Committee, the term of the SAR will be extended for a period of 30 days following the end of the legal prohibition, or until the expiration of such restrictions on transfer, unless the Committee determines otherwise.

Other Share-Based Awards

Under the Incentive Equity Plan, the Committee may grant other types of awards that are based on, or measured by, Common Shares, and granted to anyone eligible to participate in the Incentive Equity Plan. The Committee will determine the terms and conditions of such awards. Other share-based awards may be payable in cash, Common Shares or a combination of the two, as determined by the Committee.

Dividend Equivalents

Under the Incentive Equity Plan, the Committee may grant dividend equivalents in connection with grants of share units or other share-based awards made under the Incentive Equity Plan. Dividend equivalents entitle the participant to receive amounts equal to ordinary dividends that are paid on the shares underlying a grant while the grant is outstanding. The Committee will determine whether dividend equivalents will be paid currently or accrued as contingent cash obligations. Dividend equivalents may be paid in cash or Common Shares. The Committee will determine the terms and conditions of the dividend equivalent grants, including whether the grants are payable upon the achievement of specific performance goals. Dividend equivalents with respect to share units or other share-based awards that vest based on performance shall vest and be paid only if and to the extent that the underlying share units or other share-based awards vest and are paid as determined by the Committee.

Change of Control

If the Company experiences a change of control where the Company is not the surviving company (or survives only as a subsidiary of another company), unless the Committee determines otherwise, all outstanding grants that are not exercised or paid at the time of the change of control will be assumed, or replaced with grants (with respect to cash, securities or a combination thereof) that have comparable terms, by the surviving company (or a parent or subsidiary of the surviving company).

If there is a change of control and all outstanding grants are not assumed, or replaced with grants that have comparable terms, by the surviving company, the Committee may (but is not obligated to) make adjustments to the terms and conditions of outstanding grants, including, without limitation, taking any of the following actions (or combination thereof) without the consent of any participant:

In general terms, a change of control under the Incentive Equity Plan occurs if:

Deferrals

The Committee may permit or require participants to defer receipt of the payment of cash or the delivery of Common Shares that would otherwise be due to the participant in connection with a grant under the Incentive Equity Plan. The Committee will establish the rules and procedures applicable to any such deferrals, consistent with the requirements of Section 409A of the Code.

Withholding

All grants under the Incentive Equity Plan are subject to applicable U.S. federal (including taxes under FICA), state, and local, foreign or other tax withholding requirements. The Company may require participants or other persons receiving grants or exercising grants to pay an amount sufficient to satisfy such tax withholding requirements with respect to such grants, or the Company may deduct from other wages and compensation paid by the Company the amount of any withholding taxes due with respect to such grant.

The Committee may permit or require that tax withholding obligation with respect to grants paid in Common Shares be paid by having shares withheld up to an amount that does not exceed the participant’s minimum applicable withholding tax rate for U.S. federal (including FICA), state, and local tax liabilities, or as otherwise determined by the Committee. In addition, the Committee may, in its discretion, and subject to such rules as the Committee may adopt, allow participants to elect to have such share withholding applied to all or a portion of the tax withholding obligation arising in connection with any particular grant.

Transferability

Except as permitted by the Committee with respect to non-qualified stock options, only a participant may exercise rights under a grant during the participant’s lifetime. Upon death, the personal representative or other person entitled to succeed to the rights of the participant may exercise such rights. A participant cannot transfer those rights except by will or by the laws of descent and distribution or, with respect to grants other than incentive stock options, pursuant to a domestic relations order. The Committee may provide in a grant instrument that a participant may transfer non-qualified stock options for no consideration to a permitted assign in compliance with applicable securities laws.

Amendment; Termination

The Board may amend or terminate the Incentive Equity Plan at any time, except that the Company’s shareholders must approve an amendment if such approval is required in order to comply with the Code, applicable laws or applicable stock exchange requirements. Unless terminated sooner by the Board or extended with shareholder approval, the Incentive Equity Plan will terminate on the day immediately preceding the tenth anniversary of the effective date of the Incentive Equity Plan.

Shareholder Approval

Except in connection with certain corporate transactions, including stock dividends, stock splits, a recapitalization, a change in control, a reorganization, a merger, an amalgamation, a consolidation, and a spin-off, shareholder approval is required (i) to reduce the exercise price or base price of outstanding stock options or SARs, (ii) to cancel outstanding stock options or SARs in exchange for the same type of grant with a lower exercise price or base price, and (iii) to cancel outstanding stock options or SARs that have an exercise price or base price above the current price of a Common Share, in exchange for cash or other securities, each as applicable.

Clawback

All grants under the Incentive Equity Plan (including any proceeds, gains or other economic benefit actually or constructively received upon receipt of any grant or receipt or resale of any Common Shares underlying the grant) will be subject to any applicable policies implemented by the Board, which may be adopted in the future and be amended from time to time, including any clawback or recoupment policies and share trading policies. Additionally, on November 22, 2023, the Board adopted a Clawback Policy consistent with Nasdaq Listing Rule 5608, which requires the Company to recoup incentive-based compensation from current and former executive officers in the event of an accounting restatement, subject to certain exceptions as provided by the Listing Rule.

Performance Measures

Under the Incentive Equity Plan, the grant, vesting, exercisability or payment of certain awards, or the receipt of Common Shares subject to certain awards, may be made subject to the satisfaction of performance measures. The performance goals applicable to a

particular award will be determined by the Committee at the time of grant. One or more of the following business criteria for the Company may be used by the Committee in establishing performance measures under the Incentive Equity Plan: cash flow; free cash flow; earnings (including gross margin, 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, adjusted earnings before interest, taxes, depreciation and amortization and net earnings); earnings per share; growth in earnings or earnings per share; book value growth; share price; return on equity or average shareholder equity; total shareholder return or growth in total shareholder return either directly or in relation to a comparative group; return on capital; return on assets or net assets; revenue, growth in revenue or return on sales; sales; expense reduction or expense control; expense to revenue ratio; income, net income or adjusted net income; operating income, net operating income, adjusted operating income or net operating income after tax; operating profit or net operating profit; operating margin; gross profit margin; return on operating revenue or return on operating profit; regulatory filings; regulatory approvals, litigation and regulatory resolution goals; other operational, regulatory or departmental objectives; budget comparisons; growth in shareholder value relative to established indexes, or another peer group or peer group index; development and implementation of strategic plans and/or organizational restructuring goals; development and implementation of risk and crisis management programs; improvement in workforce diversity; compliance requirements and compliance relief; safety goals; productivity goals; workforce management and succession planning goals; economic value added (including typical adjustments consistently applied from generally accepted accounting principles required to determine economic value added performance measures); measures of customer satisfaction, employee satisfaction or staff development; development or marketing collaborations, formations of joint ventures or partnerships or the completion of other similar transactions intended to enhance the enGene’s revenue or profitability or enhance its customer base; merger and acquisitions; and other similar criteria as determined by the Committee. Performance goals may be established on an absolute or relative basis and may be established on a corporate-wide basis or with respect to one or more business units, divisions, subsidiaries or business segments. Relative performance may be measured against a group of peer companies, a financial market index or other objective and quantifiable indices.

Retirement Plans

We maintain a US tax-qualified retirement plan that provides eligible employees with an opportunity to save for retirement on a US tax-advantaged basis. All participants’ interests in their contributions are 100% vested when contributed. Contributions are allocated to each participant’s individual account and are then invested in selected investment alternatives according to the participants’ directions. The retirement plan is intended to qualify under Section 401(a) of the Code. We contribute 3% of an individual’s eligible compensation to the 401(k) Plan irrespective of employee contribution.

We maintain a Canadian tax-qualified retirement plan that provides eligible employees with an opportunity to save for retirement on a Canadian tax-advantaged basis. All participants’ interests in their contributions are 100% vested when contributed. Contributions are allocated to each participant’s individual account and are then invested in selected investment alternatives according to the participants’ directions. We contribute 1.5% to the Registered Retirement Savings Plan (RRSP) irrespective of employee contribution.

Director Compensation

We compensate non-employee members of our Board for their service using a combination of cash and equity compensation. Directors who are also employees do not receive any compensation for service on the Board in addition to compensation payable for their service as our employees. The non-employee members of our Board are also reimbursed for travel, lodging, and other reasonable expenses incurred in attending Board or committee meetings. See the “Summary Compensation Table” above for a discussion of our Chief Executive Officer’s compensation and awards granted in the fiscal year ended October 31, 2025.

During the fiscal year ended October 31, 2025, we compensated our non-employee directors pursuant to the non-employee compensation policy established by our Board, upon the recommendation of our compensation committee:

______________

The stock options granted to our non-employee directors for service on our Board or its committees have an exercise price equal to the fair market value of the Common Shares on the date of grant, expire ten years after the date of grant, and are subject to the director’s continued service on our Board.

The following table sets forth information concerning the compensation for our non-employee directors during the fiscal year ended October 31, 2025.

Policies and Practices Related to the Grant of Certain Equity Awards

Our Board has adopted guidelines for granting equity-based awards in order to provide a clear and consistent framework for various types of equity awards, including incentive stock options, stock appreciation rights, and share awards. These awards may be granted either under the Incentive Equity Plan or as inducement grants outside of the Incentive Equity Plan. The guidelines are designed to ensure that all equity awards comply with relevant laws and regulations, stock exchange requirements, the Company’s governance policies, and the terms outlined in the Incentive Equity Plan. The guidelines provide for the grant of equity awards in connection with the Company’s annual compensation process, annual grants to directors, in connection with new hires and for promotions, retention or purposes other than annual or new hire grants, and further provide that all such grants may only occur at a time when the Company is not in possession of material nonpublic information.

During the fiscal year ended October 31, 2025, no named executive officer received a grant of stock options during the period beginning four business days before, and ending one business day after, the filing of a periodic report on Form 10-Q or Form 10-K, or the filing or furnishing of a current report on Form 8-K that disclosed material nonpublic information (excluding disclosure of any material new option award grant under Item 5.02(e) of Form 8-K). The Company does not time the disclosure of material nonpublic information for the purpose of affecting the value of executive compensation.

Security Ownership of Certain Beneficial Owners and Management

The following table sets forth information known to the Company regarding the beneficial ownership of the Company’s Common Shares as of February 17, 2026 by:

As of February 17, 2026, 66,989,466 Common Shares were issued and outstanding. Unless otherwise indicated, we believe that all persons named in the below table have sole voting and investment power with respect to all Common Shares beneficially owned by them. Except as otherwise noted herein, the number and percentage of Common Shares beneficially owned is determined in accordance with Rule 13d-3 of the Exchange Act, and the information is not necessarily indicative of beneficial ownership for any other purpose. Under such rule, a person is deemed to be a beneficial owner of a security if that person has sole or shared voting power, which includes the power to vote or to direct the voting of the security, or investment power, which includes the power to dispose of or to direct the disposition of the security. In determining beneficial ownership percentages, we deem shares that a person will have the right to acquire within 60 days following February 17, 2026, if any, to be outstanding and to be beneficially owned by the person with such right to acquire additional Common Shares for the purposes of computing the percentage ownership of that person (including in the total when calculating the applicable beneficial owner’s percentage of ownership), but we do not treat them as outstanding for the purpose of computing the percentage ownership of any other person.

Unless otherwise indicated, the address of each person named below is 4868 Rue Levy, Suite 220, Saint-Laurent, QC, Canada H4R 2P1.
