The Reporting Persons and Mr. Alwin intend to monitor the performance and corporate governance of the Company, as well as the actions of the Company's management and board. As they deem necessary, the Reporting Persons and Mr. Alwin will assert their stockholder rights.

To the extent the actions described herein may be deemed to constitute a "control purpose" with respect to the Exchange Act and the regulations thereunder, the Reporting Persons and Mr. Alwin have such a purpose. Except as noted in this Schedule 13D, the Reporting Persons and Mr. Alwin do not have any plans or proposals, which relate to, or would result in, any of the matters …The first part of Item 4 of the SCHEDULE 13D/A filed 2026-02-24; 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.
