Purpose of Transaction (Item 4)
Stilwell Joseph
We are filing this Third Amendment to announce that we have served our notice of intent to nominate Mark D. Alcott for election as a director at the Issuer's upcoming 2027 annual meeting of shareholders (the "2027 Annual Meeting"), with Corissa B. Porcelli as our alternate nominee. Copies of the Nominee Agreements (as defined below) are attached as Exhibits 2 and 3 to this Third Amendment. Additionally, we have submitted a non-binding proposal (the "Sale Proposal") seeking shareholder approval of a request that the Board shall take all necessary steps to promptly effectuate a sale of the Issuer. A copy of the Sale Proposal is attached hereto as Exhibit 5 and is incorporated herein by reference. Our purpose in acquiring shares of Common Stock of the Issuer is to profit from the appreciation in the market price of the shares of Common Stock through asserting shareholder rights. We do not believe the value of the Issuer's assets is adequately reflected in the current market price of the Issuer's Common Stock. THIS THIRD AMENDMENT MAY BE DEEMED TO BE SOLICITATION MATERIAL IN RESPECT OF THE SOLICITATION OF PROXIES BY THE 13D GROUP FROM THE ISSUER'S SHAREHOLDERS IN CONNECTION WITH THE ISSUER'S 2027 ANNUAL MEETING. SECURITY HOLDERS ARE ADVISED TO READ THE PROXY STATEMENT AND OTHER DOCUMENTS RELATING TO THE SOLICITATION BY THE 13D GROUP AND OTHER PARTICIPANTS OF PROXIES FROM THE ISSUER'S SHAREHOLDERS FOR USE AT THE ISSUER'S 2027 ANNUAL MEETING OF SHAREHOLDERS WHEN THEY BECOME …The first part of Item 4 of the SCHEDULE 13D/A filed 2026-08-27; 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.
