Share-Based Payment Arrangement [Abstract] |
Share-Based Compensation | 10. Share-Based Compensation Amended and Restated enGene Therapeutics Inc. 2023 Incentive Equity Plan The Company's Amended and Restated enGene Therapeutics Inc. 2023 Incentive Equity Plan (the "2023 Plan") was adopted on May 15, 2024 and superseded all prior plans. The 2023 Plan is administered by the Board or, at the discretion of the Board, by a committee of the Board, (the "Committee"). The exercise prices, vesting and other restrictions are determined at the discretion of the Board, or its committee if so delegated, except that the exercise price per share of stock options may not be less than 100% of the fair market value of the Common Shares on the date of grant and the term of stock option may not be greater than ten years. Common Shares that are expired, terminated, surrendered or cancelled under the 2023 Plan without having been fully exercised will be available for future awards. The Plan authorizes the award of incentive stock options, or ISOs, non-qualified stock options, or NQSOs, Stock Units, Stock Appreciation Rights, or SARs, and other share-based awards including performance awards and share bonus awards. The Plan contains the evergreen provision (the "Evergreen Provision") pursuant to which on the first business day of each calendar year, the aggregate number of Common Shares that could be issued or transferred thereunder (the "Plan Share Reserve") and the number of Common Shares available for options intended to qualify as incentive stock options (the "ISO Sublimit") each increase by such number of Common Shares as equals 5% of the aggregate number of Common Shares outstanding on the final day of the immediately preceding calendar year (or such smaller number of shares as is determined by the compensation committee), and the ISO Sublimit by the lesser of 2,500,000 Common Shares and the increase in the Plan Share Reserve (or such smaller number of shares may be determined by the compensation committee of the Company’s board of directors). On January 1, 2026, the Committee allowed the full 5% increase for 2026 under the Evergreen Provision. As of April 30, 2026, inclusive of (i) the Common Shares subject to the outstanding grants under the prior plans, and (ii) 3,349,283 Common Shares added effective January 1, 2026 under the Evergreen Provision, the re were 11,882,624 of Common Shares reserved for issuance under the Plan and there are 2,916,016 shares remaining for issuance. 2025 Employee Stock Purchase Plan On June 10, 2025, at its 2025 Annual General Meeting of shareholders, the shareholders of enGene Therapeutics Inc. approved the adoption of the 2025 Employee Stock Purchase Plan (the "ESPP”), pursuant to which 2,000,000 common shares of the Company, no par value, will be reserved for issuance. The price of common stock purchased under the ESPP is equal to 85% of the lower of the fair market value of the common stock on the first trading day of the offering period or the relevant purchase date and is subject to change by a Plan Administrator prior to each purchase period. As of April 30, 2026, there were no shares issued and 2,000,000 shares remained available for issuance. Inducement Grants The Company may grant an inducement equity award consisting of a non-qualified stock option to purchase Common Shares to newly hired employees as an inducement material to such employees entering into employment with the Company in accordance with NASDAQ Listing Rule 5635(c)(4), which awards are granted outside of the 2023 Plan. No inducement awards have been granted during the three and six months ended April 30, 2026.
