On June 15, 2026, the Company announced the implementation of a plan to reduce its workforce by approximately 50% to streamline operations and preserve cash. The Company’s board of directors (the “Board”) approved this strategic restructuring, effective June 14, 2026, in order to preserve shareholder capital as the Company awaits additional durability data and meetings with the Food and Drug Administration (“FDA”) in connection with the Company’s LEGEND pivotal cohort. The Company has retained personnel and resources required to meet its key strategic goals and milestones, including completion of the LEGEND Cohort 1; enrolling the detalimogene plus surfactant cohort; meeting with the FDA and planning for Biologics License Application (“BLA”) initiation in the second half of 2026; and completing necessary pre-commercial activities required to support the commercial launch of detalimogene in 2027, if approved. The Company currently estimates it will incur restructuring costs of approximately $5.7 to $6.4 million, consisting primarily of employee severance, benefits, and other related costs, as well as approximately $4.7 million to $5.0 million in non-cash stock-based compensation expense primarily associated with accelerated vesting of stock options.

~~Proposal~~Further, 2in –connection ~~Appointment~~with the strategic restructuring, on June 14, 2026, the Company’s board of directors approved performance-based cash retention bonus awards for certain executive employees and ~~Remuneration~~the non-executive employees of ~~Auditor~~the Company. Subject to remaining actively employed and in good standing with the Company, aggregate cash retention bonus awards of approximately $1.7 million will be paid upon the achievement of two milestones: (i) the completion of the pre-BLA meeting with the FDA relating to detalimogene on or prior to December 31, 2026 and (ii) confirmation from the FDA that the Company’s filing of the BLA with the FDA with respect to detalimogene has been completed and accepted by the FDA, provided that such confirmation is received by the Company from the FDA no later than September 30, 2027.

The estimated charges that the Company expects to incur as a result of the restructuring are subject to several assumptions, and actual results may differ materially from these estimates. The Company may incur additional costs due to events associated with or resulting from the strategic restructuring and workforce reduction. The Company expects to record the majority of these expenses in the second half of 2026.

Separation of Chief Financial Officer

In connection with the strategic restructuring, on June 15, 2026, the Company announced that its Chief Financial Officer, Ryan Daws, will depart the Company effective July 15, 2026 (the “Daws Separation Date”). The Company, through its subsidiary, enGene USA, Inc. (“enGene USA”), expects to enter into a separation and general release agreement with Mr. Daws (the “Daws Separation

Agreement”), that will supplement the Amended and Restated Employment Agreement, dated June 10, 2025, between Mr. Daws and enGene USA.

If the parties enter into the Daws Separation Agreement, in exchange for his execution and non-revocation of a customary release, Mr. Daws will be entitled to (i) continuation of his base salary for a period of twelve months, in a total amount of $517,880, to be paid over the length of such term; (ii) subject to Mr. Daws’ continued copayment of health insurance premium amounts, a monthly payment equal to the employer payment toward twelve months of continued health insurance benefits, (iii) payment of a prorated portion of his 2026 target annual bonus and (iv) acceleration and vesting of any then unvested time-based equity awards that would have vested in the twelve-month period following the Separation Date.

On June 14, 2026, the Board appointed Kathleen Richton as Senior Vice President, Finance of the Company, with her appointment to become effective on or about July 16, 2026.

Ms. Richton, 48, has served as Vice President, Controller of the Company since March 2026. Ms. Richton also served as Executive Director of Finance of the Company from January 2025 to March 2026.

The Company, through its subsidiary enGene USA, expects to enter into an employment agreement with Ms. Richton, to be effective on or about July 15, 2026 (the “Richton Employment Agreement”). If the parties enter into the Richton Employment Agreement, it is anticipated such agreement will have no fixed term and be terminable at will, and will entitle Ms. Richton to an annual base salary of $370,000, to an annual 35% bonus opportunity, and to participate in employee benefit plans. In addition, (a) upon the termination of Ms. Richton’s employment by enGene USA without Cause (as defined in the Richton Employment Agreement) or by Ms. Richton for Good Reason (as defined in the Richton Employment Agreement), Ms. Richton will be entitled to receive post-termination severance benefits from enGene USA consisting of (i) twelve months’ base salary, (ii) twelve months of continued health insurance benefits, (iii) a prorated portion of her annual bonus, if such termination occurs six months or more into the applicable performance period for such annual bonus, and (iv) acceleration and vesting of any then unvested time-based equity awards that would have vested in the twelve-month period following such termination; and (b) upon the termination of Ms. Richton by enGene USA without Cause or by Ms. Richton for Good Reason during a change in control period, which includes the ninety days prior to and twelve months following a change in control, the Company expects that Ms. Richton will be entitled to receive post-termination severance benefits from enGene USA consisting of (i) twelve months’ base salary, (ii) an amount equal to her annual bonus opportunity at the target level, (iii) twelve months of post-termination health insurance benefits; and (iv) acceleration and vesting of all then unvested time-based equity awards. In addition, the Company expects that the Richton Employment Agreement will provide for standard restrictive covenant obligations for Ms. Richton, including a noncompete and nonsolicit obligation which will run while employed and for twelve months thereafter.

If the parties enter into the Richton Employment Agreement, the Company intends to file a copy of such agreement as an exhibit to the Company’s Quarterly Report on Form 10-Q for the period ended July 31, 2026.
