1. Item 3 of the Schedule 13D is hereby amended and restated in its entirety as follows: Merger Shares & Pre-Funded Warrants As more fully described in Items 4 and 6 below, on March 30, 2023, the Issuer, Dawn Merger Sub, Inc., a Delaware corporation and a wholly-owned subsidiary of the Issuer ("Merger Sub"), and EIP Pharma, Inc., a Delaware corporation ("EIP"), entered into an Agreement and Plan of Merger (as amended from time to time, the "Merger Agreement"), pursuant to which, among other things, and subject to the satisfaction or waiver of certain conditions set forth in the Merger Agreement, at the effective time of the merger (the "Effective Time"), Merger Sub merged with and into EIP, with EIP continuing as a wholly-owned subsidiary of Issuer and the surviving corporation of the merger (the "Merger"). The closing of the Merger occurred on August 16, 2023 (the "Closing Date") and, at the Effective Time, the Issuer filed an amendment to its certificate of incorporation to change its name from "Diffusion Pharmaceuticals Inc." to "CervoMed Inc." Pursuant to the terms of the Merger Agreement, effective as of the Closing Date and after giving effect to the Merger exchange ratio of 0.1151 shares of Common Stock for each share of EIP capital stock and a 1-for-1.5 reverse stock split of the Common Stock implemented by the Issuer immediately prior to the Effective Time: - 823,407 shares of EIP common stock, 694,652 shares of EIP Series A-2 preferred stock, and 365,670 shares of EIP common stock issued upon conversion of EIP convertible notes, in each case, owned directly by the Reporting Person converted into the right to receive, in the aggregate, 216,817 shares of Common Stock. - 472,303 shares of EIP common stock and 820,000 shares of EIP common stock issued upon conversion of EIP convertible notes, in each case, owned by The Joshua S. Boger 2021 Trust DTD 12/09/2021 (the "JSB 2021 Trust") converted into the right to receive, in the aggregate, 148,744 shares of Common Stock. The Reporting Person is the sole trustee of the JSB 2021 Trust. - 1,700,680 shares of EIP common stock issued upon conversion of EIP convertible notes owned by The Amy S. Boger 2021 Trust (the "ASB 2021 Trust") converted into the right to receive, in the aggregate, 195,748 shares of Common Stock. The Reporting Person is the sole trustee of the ASB 2021 Trust. - 3,428,571 shares of EIP Series B preferred stock and 880,689 shares of EIP common stock issued upon conversion of EIP convertible notes, in each case, owned by the JSB 2021 Trust converted into the right to receive a pre-funded warrant to purchase, in the aggregate, 495,995 shares of Common Stock at an exercise price of $0.001 per share (the "Pre-Funded Warrant"). The Pre-Funded Warrant was originally subject to certain limitations with respect to any exercise that would result in the Reporting Person beneficially owning in excess of 9.99% of the outstanding Common Stock after giving effect to such exercise and, accordingly, were excluded from the Reporting Person's beneficial ownership. On February 26, 2024, the Issuer and the JSB 2021 Trust entered into an amendment (the "Warrant Amendment") to the Pre-Funded Warrant pursuant to which the parties eliminated the beneficial ownership limitation. On February 26, 2024, following the effectiveness of the Warrant Amendment, the Pre-Funded Warrant was exercised in full on a cashless basis. In accordance with the terms of the Pre-Funded Warrant, 36 shares of Common Stock were withheld in lieu of a cash payment of the exercise price and the JSB 2021 Trust was issued the remaining 495,959 shares of Common Stock underlying the Pre-Funded Warrant. Stock Options Effective as of February 7, 2024, the Reporting Person was appointed as a member and the non-executive chairperson (the "Chair") of the board of directors of the Issuer (the "Board"). In connection with the Reporting Person's service on the Board and pursuant to the Issuer's non-employee director compensation program and the terms of the Issuer's form of stock option agreement (the "Option Agreement"), the Reporting Person has been granted stock options to purchase, in the aggregate, 32,000 shares of Common Stock, of which 23,541 shares are exercisable within 60 days of June 11, 2026. 2026 Private Placement On June 11, 2026, the Issuer completed a private placement (the "Private Placement") pursuant to a securities purchase agreement, dated June 9, 2026 (the "Purchase Agreement"), with the JSB 2021 Trust, and certain other accredited investors named therein. Pursuant to the Purchase Agreement, the JSB 2021 Trust purchased an aggregate of 955,414 units (the "Units"), each Unit comprised of (i) one share of the Issuer's Common Stock, (ii) one Series B warrant to purchase one share of Common Stock or a pre-funded warrant to purchase one share of Common Stock (each, a "Series B Warrant"), and (iii) one Series C warrant to purchase one share of Common Stock or a pre-funded warrant to purchase one share of Common Stock (each, a "Series C Warrant", and together with the Series B Warrants, the "Warrants") (the shares of Common Stock issuable upon exercise of the Warrants or any pre-funded warrants, the "Warrant Shares") for a purchase price of $3.14 per Unit. The Series B Warrants have an exercise price equal to $3.32 per Warrant Share or $3.319 per pre-funded warrant, are exercisable immediately, and will expire five years from the issuance date of the Series B Warrant. The Series C Warrants have an exercise price equal to $3.14 per Warrant Share or $3.139 per pre-funded warrant, are exercisable immediately, and will expire one year from the issuance date of the Series C Warrant. Under the terms of the Series B Warrants and the Series C Warrants, the Issuer may not effect the exercise of any portion thereof, and the JSB 2021 Trust will not have the right to exercise any portion thereof, which, upon giving effect to such exercise, would cause the JSB 2021 Trust (together with its affiliates and other attribution parties) to own more than 19.99% of the number of shares of Common Stock outstanding immediately after giving effect to such exercise. To the extent that exercise of the Series B Warrants or Series C Warrants will result in the JSB 2021 Trust (together with its affiliates and other attribution parties) beneficially owning shares of Common Stock above such ownership limitations, the JSB 2021 Trust may exercise its Series B Warrants or Series C Warrants for pre-funded warrants to purchase shares of Common Stock, which pre-funded warrants will include a substantially similar maximum ownership limitation. The foregoing descriptions of the Merger Agreement, the Pre-Funded Warrant, the Warrant Amendment, the Option Agreement, the Purchase Agreement, the Series B Warrant, and the Series C Warrant are qualified in their entirety by reference to the full text thereof, copies of which are filed as exhibits to this Schedule 13D and incorporated herein by reference.

As of the date of this Schedule 13D, the Reporting Person may be deemed to beneficially own, in the aggregate, 2,204,143 shares of Common Stock, which represents approximately 19.99% of the shares of Common Stock outstanding. The Reporting Person (together with its affiliates and other attribution parties) holds (i) 216,817 shares of Common Stock owned directly by the Reporting Person, (ii) 1,600,117 shares of Common Stock held by the JSB 2021 Trust, (iii) 195,748 shares of Common Stock held by the ASB 2021 Trust, (iv) 955,414 shares of Common Stock underlying Series B Warrants held by the JSB 2021 Trust, (v) 955,414 shares of Common Stock underlying Series C Warrants held by the JSB 2021 Trust, and (vi) 32,000 shares of Common Stock underlying stock options granted to the Reporting Person for service on the Issuer's Board.

Accordingly, the securities reported as beneficially owned by the Reporting Person consist of (i) 2,012,682 shares of Common Stock, (ii) 23,541 shares of Common Stock underlying options exercisable within 60 days of June 11, 2026, and (ii) an aggregate of 167,920 shares of Common Stock that may be acquired upon the exercise of Series B Warrants and/or Series C Warrants, as limited by the Maximum Ownership Limitation. The Reporting Person is currently prohibited from exercising the Series B Warrants and/or Series C Warrants to the extent that such exercise would result in its beneficial ownership of more than 2,204,143 shares of Common Stock. The Reporting Person disclaims beneficial ownership of the securities held by the ASB 2021 Trust and the JSB 2021 Trust, except as to his pecuniary interest therein (if any), and this report shall not be deemed an admission that the Reporting Person is the beneficial owner of such securities for purposes of Section 13 or for any other purpose. The foregoing beneficial ownership is based on an aggregate of 11,026,233 shares of Common Stock outstanding based on (i) 9,258,719 shares of Common Stock as of May 6, 2026, as reported in the Issuer's Quarterly Report on Form 10-Q filed with the SEC on May 15, 2026, and (ii) 1,767,514 shares of Common Stock issued in the Issuer's private placement completed June 11, 2026, as reported in the Issuer's Current Report on Form 8-K filed with the SEC on June 10, 2026.
