On August 22, 2025, Alpha Cognition Inc. (the “Company”) entered into an At the Market Offering Agreement (the “ATM Agreement”) with H.C. Wainwright & Co., LLC (“Wainwright”) as sales agent. Under the terms of the ATM Agreement, the Company will be entitled to sell, at its sole discretion and from time to time as it may choose, common shares in the capital of the Company (“Shares”) through Wainwright, with such sales having an aggregate gross sales value of up to US$75.0 million (the “Offering”). The ATM Agreement will remain in full force and effect until the date that the ATM Agreement is terminated in accordance with the terms therein.

Subject to the terms and conditions of the Agreement, Wainwright will use its commercially reasonable efforts to sell the Shares from time to time, based upon the Company’s instructions. The Company has provided Wainwright with customary indemnification rights, and Wainwright will be entitled to a commission at a commission rate of up to 3.0% of the gross sales price of the Shares sold.

Sales of the Shares, if any, under the Agreement may be made in transactions that are deemed to be “at the market offerings” as defined in Rule 415 under the Securities Act of 1933, as amended (the “Securities Act”), including sales made by means of ordinary brokers’ transactions, including on the Nasdaq Capital Market, at market prices or as otherwise agreed with Wainwright. The Company has no obligation to sell any of the Shares, and may at any time suspend offers under the Agreement or terminate the Agreement.

This report shall not constitute an offer to sell or the solicitation of an offer to buy nor shall there be any sale of the Shares in any state in which such offer, solicitation or sale would be unlawful prior to registration or qualification under the securities laws of any such state.

The ATM Agreement was filed as an exhibit to the Company’s shelf registration statement on Form S-3 (File No. 333-289792) previously filed with the Securities and Exchange Commission on August 22, 2025 (the “Registration Statement”). The description of the material terms of the ATM Agreement above is qualified in its entirety by reference to the ATM Agreement filed as Exhibit 1.2 to the Registration Statement.
