On June 17, 2025, the Company entered into a Securities Purchase Agreement (the “Purchase Agreement”) with institutional accredited investors whereby the Company offered units consisting of a share of Series A Non-Voting Convertible Preferred Stock (“Series A Preferred Stock”) and a warrant to purchase six shares of common stock.

RSUs have been granted to directors, employees and contractors in accordance with the Company’s Amended and Restated 2018 Omnibus Stock Incentive Plan (the “2018 Omnibus Plan”). Some RSUs are subject to delayed delivery of the shares underlying the vested RSUs until the termination of grantee service.

As of June 30, 2026, there was $6.4 million of unrecognized stock-based compensation expense related to RSUs which will be recognized over a weighted average period of 1.8 years.

Treasury Stock

On December 29, 2025, 82,324 shares were withheld from a delivery of RSUs to the Company’s Chief Executive Officer to cover the Company’s tax obligations, reflected as treasury stock as of December 31, 2025. The Company records repurchases of its own common stock at cost. Repurchased common stock is presented as a reduction of equity in the condensed balance sheets. Gains resulting from differences between the cost of treasury stock and the re-issuance proceeds would be credited to additional paid-in capital. Losses resulting from differences between the cost of treasury stock and the re-issuance proceeds would be debited to additional paid-in capital.

On March 20, 2026, the Company’s Board of Directors, pursuant to Section 243 of the Delaware General Corporation Law, approved a resolution whereby shares of the Company’s common stock that are withheld in the future upon vesting of the RSUs or exercise of options to satisfy tax withholding obligations or the exercise price of options, as the case may be, will automatically be retired and such shares will (1) resume the status of authorized but unissued shares of common stock and (2) again become available for issuance pursuant to inducement grants or the 2018 Omnibus Plan, as the case may be. As a result of the retirement, the Company derecognized the treasury shares to additional paid in capital during the six months ended June 30, 2026.

There was no treasury stock activity in the three months ended June 30, 2026.
