Item 4 of the Schedule 13D is hereby amended and supplemented as follows: As disclosed in Amendment No. 2 to the Schedule 13D filed by Yaacov (Kobe) Nagar on January 23, 2026, Mr. Nagar was no longer a member of the group as of January 22, 2026. On February 8, 2026, the Issuer appointed Mr. McKnight to the Board, effective February 9, 2026, to fill the vacancy created by the resignation of James Vanderhider from the Board. Mr. Vanderhider's resignation and Mr. McKnight's appointment were made in accordance with the Agreement between Mr. Nagar and the Issuer. Mr. McKnight is the third candidate that was mutually acceptable to both the Issuer and Mr. Nagar pursuant to the terms of the Agreement. Accordingly, the Reporting Persons have each determined independently that they are no longer deemed to be acting as a "group," as that term is used in Section 13(d) of the Exchange Act and the rules thereunder.Item 4 of the SCHEDULE 13D/A filed 2026-03-12

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.
