The aggregate number and percentage of the Common Stock beneficially owned by each Reporting Person are set forth on Rows 11 and 13 of the cover pages of this Schedule 13D and are incorporated herein by reference. Calculations of the percentage of the shares of Common Stock beneficially owned are based on the 2,838,697 shares of Common Stock outstanding as of November 2, 2026, as reported in the Issuer's Quarterly Report on Form 10-Q filed on November 4, 2026, as adjusted to include the 789,686 shares of Common Stock issuable upon conversion of the 115,000 shares of Series A Preferred Stock. This Amendment No. 4 is being filed to report a greater than 1% increase in the Reporting Persons' beneficial ownership that was due solely to the decrease in outstanding shares of Common Stock as disclosed by the Issuer. As of September 15, 2026, Aggregator LP directly holds 115,000 shares of Series A Preferred Stock (after giving effect to the accrual of dividends in kind paid thereunder as of September 15, 2026), which is currently convertible into 789,686 shares of Common Stock, calculated as the sum of the principal investment amount and accrued dividends, divided by a conversion price equal to $175.00 per share (the "Conversion Price"), and Bloom Acquisitions 1, LP, a Delaware limited partnership and an affiliate of Aggregator LP, directly holds, in the aggregate, 25,172 shares of Common Stock. On June 17, 2026, the Issuer effected a 1-for-10 reverse stock split of its issued and outstanding Common Stock (the "Reverse Stock Split"), pursuant to which every ten shares of Common Stock were automatically combined into one share of Common Stock, without any change in par value per share, and stockholders who would otherwise have been entitled to a fractional share received a cash payment in lieu thereof. In accordance with the terms of the Series A Preferred Stock, the Conversion Price was proportionately adjusted from $17.50 per share to $175.00 per share. All share numbers and the Conversion Price reported in this Amendment No. 4 reflect the Reverse Stock Split. Neither the filing of this Schedule 13D nor any of its contents shall be deemed to constitute an admission that any of the foregoing or the Reporting Persons are the beneficial owners of the Common Stock referred to herein for purposes of Section 13(d) of the Securities Exchange Act of 1934, as amended, or for any other purpose.

The aggregate number of shares of Common Stock as to which each Reporting Person has sole power to vote or to direct the vote, shared power to vote or to direct the vote, sole power to dispose or to direct the disposition, or shared power to dispose or to direct the disposition is set forth on Rows 7 through 10 of the cover pages of this Schedule 13D and is incorporated herein by reference. Aggregator GP exercises sole voting and investment discretion over the reported securities. Holdings is the sole shareholder and director of Fund IV GP Ltd., the sole member of Aggregator GP, and therefore Holdings and the Holdings Members may be deemed to beneficially own the reported securities but disclaim such beneficial ownership.

Except as otherwise disclosed in this Amendment No. 4, the Reporting Persons have effected no transactions in Common Stock within the prior 60 days.
