Initial Financing In July 2026, Velaris Therapeutics, Inc., a Delaware corporation ("Velaris"), issued and sold an aggregate of 20,000,000 shares of Velaris preferred stock to Fund II at a purchase price of $0.01 per share. Agreement and Plan of Merger On October 13, 2026, the Company acquired Velaris in accordance with the terms of the Agreement and Plan of Merger, dated October 13, 2026 (the "Merger Agreement"), by and among the Company, Valkyrie Merger Sub I, Inc., a Delaware corporation and a wholly owned subsidiary of the Company ("First Merger Sub"), Valkyrie Merger Sub II, LLC, a Delaware limited liability company and wholly owned subsidiary of the Company ("Second Merger Sub"), and Velaris. Pursuant to the Merger Agreement, First Merger Sub merged with and into Velaris, pursuant to which Velaris was the surviving corporation and became a wholly owned subsidiary of the Company (the "First Merger"). Immediately following the First Merger, Velaris merged with and into Second Merger Sub, pursuant to which Second Merger Sub was the surviving entity (together with the First Merger, the "Merger"). Under the terms of the Merger Agreement, at the closing of the Merger (the "Closing"), the Company issued to the stockholders of Velaris (i) 105,286 shares of Series B Preferred Stock and (ii) 33,054 shares of Series C Preferred Stock, each share of which is convertible into 1,000 shares of Common Stock, subject to certain conditions. Pursuant to the Merger Agreement and the Purchase Agreement (as defined below), the Company has agreed to hold a stockholders' meeting to submit the following matters to its stockholders for their consideration: (i) the approval of the conversion of the Series B Preferred Stock and the Series C Preferred Stock into shares of Common Stock in accordance with certain of the rules of the Nasdaq Stock Market LLC (the "Conversion Proposal"), (ii) the approval of an amendment to the certificate of incorporation of the Company to (A) change the name of the Company to "Velaris Therapeutics, Inc.", (B) effectuate the redomestication of the Company, (C) effectuate a reverse stock split of all outstanding shares of Common Stock at a reverse stock split ratio to be determined by the Board with the consent of the Lead Investor (as defined below), (D) increase the number of authorized shares of Common Stock sufficient to permit the conversion in full of all then outstanding shares of Series B Preferred Stock and Series C Preferred Stock (the "Authorized Share Increase") and (E) such other changes as are mutually agreeable to the Company and Velaris, and (iii) the approval of a new equity incentive plan. In connection with these matters, the Company intends to file with the Securities and Exchange Commission (the "SEC") a proxy statement and other relevant materials. The Merger Agreement further provides that, effective upon stockholder approval of the Conversion Proposal, three directors of the Company will resign from the Board and designees of the lead investor in the Financing, an affiliate of the Reporting Persons (the "Lead Investor"), will be appointed to fill the resulting vacancies, such that the director designated by Velaris and the designees of the Lead Investor will constitute four of the five members of the Board. The Merger Agreement also requires that any redomestication of the Company provide that each director elected by the holders of the Series B Preferred Stock will be entitled to three votes on each matter presented to the Board. In addition, from the Closing until the earliest of the conversion of all outstanding shares of Series B Preferred Stock following stockholder approval of the Conversion Proposal, twelve months following the Closing and the date on which the Lead Investor otherwise agrees, the Company will conduct the development of Velaris's programs in all material respects in accordance with an agreed development plan and operating budget and will not materially deviate from such plan without the consent of the Lead Investor, subject to certain exceptions. The foregoing description of the Merger and the Merger Agreement does not purport to be complete and is qualified in its entirety by reference to the Merger Agreement, which is filed as Exhibit 99.2 to this Schedule 13D and is incorporated herein by reference. Certificates of Designation On October 13, 2026, the Company filed with the Secretary of State of the State of Delaware a Certificate of Designation of Preferences, Rights and Limitations of the Series B Preferred Stock (the "Certificate of Designation of Series B Preferred Stock") and a Certificate of Designation of Preferences, Rights and Limitations of the Series C Preferred Stock (the "Certificate of Designation of Series C Preferred Stock," and together with the Certificate of Designation of Series B Preferred Stock, the "Certificates of Designation") in connection with the Merger and the Financing. The Certificates of Designation provide for the issuance of shares of Series B Preferred Stock and Series C Preferred Stock, as applicable.

Except as otherwise required by law, the Series B Preferred Stock and Series C Preferred Stock do not have voting rights. However, as long as any shares of Series B Preferred Stock or Series C Preferred Stock, as applicable, are outstanding, the Company will not, without the affirmative vote of the holders of a majority of the then outstanding shares of Series B Preferred Stock or Series C Preferred Stock, as applicable, (a) alter or change adversely the powers, preferences or rights given to the Series B Preferred Stock or Series C Preferred Stock, as applicable, (b) alter or amend the applicable Certificate of Designation, (c) amend its certificate of incorporation or other charter documents in any manner that adversely affects any rights of the holders of Series B Preferred Stock or Series C Preferred Stock, as applicable, (d) issue further shares of Series B Preferred Stock or Series C Preferred Stock, as applicable, or increase or decrease (other than by conversion) the number of authorized shares of Series B Preferred Stock or Series C Preferred Stock, as applicable, (e) prior to stockholder approval of the Conversion Proposal and the Authorized Share Increase, amend, waive or modify the Merger Agreement in any manner that would be reasonably likely to prevent, impede or materially delay such approval, or (f) enter into any agreement with respect to any of the foregoing or, for the Series B Preferred Stock, with respect to the following.

In addition, from and after stockholder approval of the Conversion Proposal, for so long as at least 30% of the originally issued Series B Preferred Stock remains issued and outstanding, the holders of the Series B Preferred Stock, voting as a separate class, will be entitled to elect two directors of the Company. Following stockholder approval of the Conversion Proposal and the Authorized Share Increase, each share of Series B Preferred Stock will be convertible, at the option of the holder, into 1,000 shares of Common Stock and each share of Series C Preferred Stock will automatically convert into 1,000 shares of Common Stock, each subject to certain limitations, including that a holder of Series B Preferred Stock or Series C Preferred Stock is prohibited from converting shares of Series B Preferred Stock or Series C Preferred Stock, as applicable, into shares of Common Stock if, as a result of such conversion, such holder, together with its affiliates, would beneficially own more than a specified percentage (to be established by the holder between 0% and 19.99%) of the total number of shares of Common Stock issued and outstanding immediately after giving effect to such conversion.
