Item 4.

Ownership

(a)

Amount beneficially owned:

The information required by this item with respect to each Reporting Person is set forth in Rows 5 through 9 and 11 of the cover pages to this Schedule 13G and is incorporated herein by reference for each such Reporting Person. The share amounts and ownership percentages disclosed on such cover pages as of the date of this Schedule 13G are based on 2,535,509 shares of Common Stock outstanding as of February 5, 2026, as disclosed in the Proxy Statement. The Reporting Persons are filing this Schedule 13G as a result of 3i's delivery of a notice to the issuer on February 20, 2026, effective 61 days thereafter, to increase the Blockers in the Warrants, the Pre-Funded Warrants, the Note, the Certificate of Designation of Preferences, Rights and Limitations of the Series B Non-Voting Convertible Preferred Stock (the "Series B Certificate of Designation") and the Certificate of Designation of Preferences, Rights and Limitations of Series C Non-Voting Convertible Preferred Stock (the "Series C Certificate of Designation") from 4.99% to 9.99%. As of the date of this Schedule 13G, 3i holds (i) 47,055 shares of Common Stock, (ii) Warrants exercisable for up to 6,515,464 shares of Common Stock, which exercises are subject to a Blocker, (iii) the Note in the principal aggregate amount of approximately $16.3 million, which conversions are subject to a Blocker, (iv) 2,155 shares of Series B Preferred Stock, which conversions are subject to a Blocker, and (v) 6,000 shares of Series C Preferred Stock, which conversions are subject to a Blocker. As of the date of this Schedule 13G, Tumim holds Pre-Funded Warrants exercisable for up to 437,012 shares of Common Stock. Due to the interaction between the Blockers in each of the Warrants, the Note, the Series B Certificate of Designation and the Series C Certificate of Designation, 3i may exercise the Warrants for and/or convert the Note, the shares of Series B Preferred Stock and the shares of Series C Preferred stock into, in any combination, an aggregate of 229,132 shares of Common Stock as a result of the triggering of the applicable Blockers, each of which prohibits 3i from exercising the Warrants for, or converting the Note, the shares of Series B Preferred Stock and the shares of Series C Preferred Stock into, shares of Common Stock if, as a result of such exercise or conversion, 3i, together with its affiliates and any persons acting as a group together with 3i or any of such affiliates, would beneficially own more than 9.99% of the total number of shares of Common Stock then issued and outstanding immediately after giving effect to such exercise or conversion. Tumim beneficially owns an aggregate of 229,132 shares of Common Stock as a result of 3i's ownership of 47,055 shares of Common Stock and the triggering of the 9.99% Blocker contained in the Pre-Funded Warrants, which prohibits Tumim from exercising the Pre-Funded Warrants for shares of Common Stock if, as a result of such exercise, the holder thereof, together with its affiliates and any persons acting as a group together with such holder or any of such affiliates, would beneficially own more than 9.99% of the total number of shares of Common Stock then issued and outstanding immediately after giving effect to such exercise. Consequently, 3i beneficially owns 276,187 shares of Common Stock (the "3i Shares") and Tumim beneficially owns 229,132 shares of Common Stock (the "Tumim Shares", and collectively with the 3i Shares, the "Shares"). 3i is the beneficial owner of the 3i Shares and has the power to dispose of and the power to vote the 3i Shares beneficially owned by it, which power may be exercised by 3i Management, the manager and general partner of 3i. Tumim is the beneficial owner of the Tumim Shares and has the power to dispose of and the power to vote the Tumim Shares beneficially owned by it, which power may be exercised by 3i Management, the manager and general partner of Tumim. Mr. Tarlow, as the manager of 3i Management, has shared power to vote and/or dispose of the Shares beneficially owned by each of 3i, Tumim and 3i Management. Mr. Tarlow does not directly own the Shares. By reason of the provisions of Rule 13d-3 of the Act, Mr. Tarlow may be deemed to beneficially own the Shares beneficially owned by 3i, Tumim and 3i Management, and 3i Management may be deemed to beneficially own the Shares beneficially owned by 3i and Tumim.
