Purpose of Transaction (Item 4)
Stilwell Joseph
We hope to work with management and the board to maximize shareholder value. 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. Members of the Group may seek to make additional purchases or sales of shares of Common Stock. Except as described in this filing, no member of the Group has any plans or proposals which relate to, or could result in, any of the matters referred to in paragraphs (a) through (j), inclusive, of Item 4 of Schedule 13D. Members of the Group may, at any time and from time to time, review or reconsider their positions and formulate plans or proposals with respect thereto. Since 2000, members or affiliates of the Group have taken an 'activist position' in 79 other publicly-traded companies. In each instance, our purpose has been to profit from the appreciation in the market price of the shares we held by asserting shareholder rights. In addition, we believed that the values of the companies' assets were not adequately reflected in the market prices of their shares. Our actions with respect to such publicly-traded companies are described in Schedule A, attached hereto and incorporated herein by reference.Item 4 of the SCHEDULE 13D filed 2026-03-31

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.
