The filing of this Schedule 13G should not be construed in and of itself as an admission by any Reporting Person as to beneficial ownership of the shares of Common Stock reported herein. The principal business address of each of the Reporting Persons is 2 Wooster Street, 2nd Floor, New York, NY 10013. 3i is a Delaware limited partnership. Tumim is a Delaware limited liability company. 3i Management is a Delaware limited liability company. Mr. Tarlow is a citizen of the United States. Y 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 Reporting Persons are filing this Schedule 13G as a result of 3i's delivery of a notice to the issuer on April 21, 2026, effective 61 days thereafter, to increase the Blockers in the Notes from 4.99% to 9.99%.

As of the date of this Schedule 13G, Tumim holds 47,800 shares of Common Stock. Due to the interaction between the Blockers in each of the Warrants and the Notes, 3i may exercise the Warrants for and/or convert the Notes, in any combination, into an aggregate of 1,271,220 shares of Common Stock as a result of the triggering of the applicable 4.99% and 9.99% Blockers, each of which prohibits 3i from exercising the Warrants for, or converting the Notes 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 4.99% or 9.99%, as applicable, of the total number of shares of Common Stock then issued and outstanding immediately after giving effect to such exercise or conversion. Consequently, 3i beneficially owns 1,271,220shares of Common Stock (the "3i Shares") and Tumim beneficially owns 47,800 shares of Common Stock (the "Tumim Shares", and collectively with the 3i Shares, the "Shares"). 3i 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 general partner of 3i.

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.
