Share-Based Payment Arrangement [Abstract] |
Share Based Compensation | 9. Share Based Compensation On September 22, 2023, in connection with the Merger, the Company adopted the CDT Equity Inc. 2023 Stock Incentive Plan (the “2023 Plan”). The 2023 Plan became effective upon the closing of the Merger. The 2023 Plan initially provided for the issuance of up to 38 shares of Common Stock. Pursuant to the 2023 Plan’s “evergreen” provision, on February 6, 2025 and January 10, 2024, the Company increased the number of shares of Common Stock available for issuance under the 2023 Plan by 23 and 12 shares, respectively. The number of authorized shares will automatically increase on January 1, 2026 and continuing annually on each anniversary thereof through (and including) January 1, 2033, equal to the lesser of (i) 5% of the shares of Common Stock outstanding on the last day of the immediately preceding fiscal year and (ii) such smaller number of shares of Common Stock as determined by the Board or the applicable committee of the Board. The 2023 Plan allows for awards to be issued to employees and non-employee directors in the form of options, stock appreciation rights, restricted stock, restricted stock units (“RSUs”), performance stock units, dividend equivalents, other stock-based, or other cash-based awards. On August 5, 2025, at the Company’s 2025 Annual Meeting of Stockholders, stockholders approved an amendment and restatement of the Company’s 2023 Stock Incentive Plan (as amended, the “Amended 2023 Stock Incentive Plan”) to authorize an additional 10,000 shares of Common Stock for awards under the Amended 2023 Stock Incentive Plan. The Amended 2023 Stock Incentive Plan was recommended and approved by the Board on July 8, 2025. On January 1, 2026, in accordance with the 2023 Plan, the number of authorized shares under the 2023 plan increased by 4,630 shares. As of March 31, 2026, there were 5,842 shares of Common Stock available for issuance under the 2023 Plan. Board of Directors Shares On March 30, 2025, certain non-employee directors elected to receive their unpaid cash retainers due through the period ended June 30, 2025, under the Director Compensation Program, in the form of fully vested shares of Common Stock. In total, $0.1 million of unpaid retainers was settled through the issuance 53 unregistered shares of Common Stock (the “Retainer Shares”). The Company recorded the Retainer Shares at their fair value, as determined by intraday share prices of the Company’s Common Stock on March 31, 2025. In relation to the Retainer Shares, the Company recorded $0.1 million of expense within general & administration expense in the unaudited condensed consolidated statement of operations and comprehensive loss during the three months ended March 31, 2025, respectively. Stock Options The Company did not grant stock options during the three months ended March 31 2026 or March 31, 2025. The Company accounts for forfeitures as they occur, which may result in the reversal of compensation costs in subsequent periods as the forfeitures arise. The following table summarizes stock option activity for the 2023 Plan: Schedule of Stock Option Activity

The aggregate intrinsic value of options is calculated as the difference between the exercise price of the underlying options and the fair value of the Company’s Common Stock for those options that had exercise prices lower than the fair value of the Company’s Common Stock. As of March 31, 2026, the total compensation cost related to non-vested option awards not yet recognized was $1.4 million with a weighted average remaining vesting period of 1.23 years. For the three months ended March 31, 2026 and 2025, there was a total of $0.2 million and $0.2 million, respectively, recorded in stock-based compensation expense recognized within general and administrative expenses on the unaudited condensed consolidated statements of operations and comprehensive loss, respectively.
