Otworth Michael
The Reporting Person is the Executive Chairman and a Class III director of the Issuer. He acquired all of his securities for investment purposes only and are being held as a long-term investment. The Reporting Person does not have any current plans or proposals which relate to or would result in any matters set forth in Items 4(a) through 4(j) of Schedule 13D.Item 4 of the SCHEDULE 13D filed 2025-08-18

Commonwealth Asset Management LP
The Reporting Persons acquired the Shares based on the Reporting Persons' belief that the Shares, when acquired, represented an attractive investment opportunity. Depending upon overall market conditions, other investment opportunities available to the Reporting Persons, and the availability of Shares at prices that would make the purchase or sale of Shares desirable, the Reporting Persons may endeavor to increase or decrease their position in the Issuer through, among other things, the purchase or sale of Shares on the open market or in private transactions or otherwise, on such terms and at such times as the Reporting Persons may deem advisable. On February 17, 2026, CWAM delivered a letter (the "CWAM Letter") to the Issuer's Board of Directors (the "Board") to, among other things, express its profound dissatisfaction with the Company's performance, governance practices, and strategic direction. As set forth in the CWAM Letter, CWAM believes that the Issuer's current business plan and financial trajectory are untenable as the Issuer continues to fund both operations and portfolio investments through ongoing dilutive and value destructive stock sales rather than organic revenue generation. CWAM believes the current state of affairs at the Issuer is particularly concerning considering that Accelsius, the Issuer's majority-owned subsidiary, has established itself as a market leader in two-phase direct-to-chip cooling for data centers, which are experiencing unprecedented …The first part of Item 4 of the SCHEDULE 13D filed 2026-02-17; the filing has the rest

Where this comes from
Anyone who comes to own more than 5% of a class of a listed company's voting shares has to tell the SEC. A holder who may seek to change or influence the company files Schedule 13D, and has to say in Item 4, "Purpose of Transaction", what it intends to do. A holder with no such intent, such as many index and passive funds, may file the shorter Schedule 13G. Both are amended when the stake changes, including when it falls below 5%.
Every row here is one of those filings, linked to the filing itself. Percentages and share counts are exactly as the holder filed them, for the holder the filing names; an amendment showing a lower figure is shown as filed. Item 4 text is quoted word for word. Where a 13D's Item 4 contains a sentence stating a definite intent to influence the company, that sentence is marked and quoted; the page does not describe the holder or its motives beyond the words it filed. Nothing here is investment advice.
