The Company believes that the allegations in the Matters are wholly without merit, that the disclosures in the proxy statement comply fully with applicable laws, and that no additional disclosures are required or necessary under applicable laws. However, to moot the disclosure claims, avoid the risk that the Matters delay or otherwise adversely affect the special meeting of the Company’s stockholders or the closing of the Transaction, and to avoid the cost and distraction of litigation, and without admitting any liability or wrongdoing, the Company is making additional disclosures as described in this Current Report on Form 8-K. The Company and its directors expressly deny that they have violated any laws, negligently misrepresented or concealed any information, or breached any fiduciary duties. Nothing in this Current Report on Form 8-K shall be deemed an admission of the legal necessity or materiality under applicable laws of any of the disclosures set forth herein or in the proxy statement. To the contrary, the Company and its directors specifically deny all allegations in the Matters and that any additional disclosure in the proxy statement was or is required.

Forward-Looking Statements

This report contains forward-looking statements within the meaning of the Private Securities Litigation Reform Act. Forward-looking statements include statements regarding the proposed merger, its timing and anticipated future results. Forward-looking statements can be identified by the fact that they do not relate strictly to historical or current facts. They often include words like “believe,” “expect,” “anticipate,” “estimate,” and “intend,” or future or conditional verbs such as “will,” “would,” “should,” “could,” or “may.” These forward-looking statements are necessarily speculative and speak only as of the date made, and are subject to numerous assumptions, risks, and uncertainties, all of which may change over time. Actual results could differ materially from such forward-looking statements. Certain factors that could cause actual results to differ materially from expected results include: failure to obtain necessary regulatory approvals (and the risk that such approvals may result in the imposition of conditions that could adversely affect the combined company); failure to obtain shareholder approvals or to satisfy any of the other conditions of the transaction on a timely basis or at all or other delays in completing the merger; the reputational risks and the reaction of Hometown’s and the Company’s customers to the transaction; the impacts of tariffs, sanctions and other trade policies of the United States and its global trading counterparts; the occurrence of any event, change, or other circumstances that could give rise to the right of one or both of the parties to terminate the merger agreement; difficulties in achieving cost savings from the merger or in achieving such cost savings within the expected time frame; difficulties in integrating the Company; increased competitive pressures; changes in the interest rate environment; changes in general economic conditions, including potential recessionary conditions; legislative and regulatory changes that adversely affect the business in which the Company is engaged; and changes in the securities markets and other risks and uncertainties. Additional factors that could cause results to differ materially from those described above can be found in the Company’s Annual Report on Form 10-K for the year ended June 30, 2024, and in its subsequent Quarterly Reports on Form 10-Q, including in the respective Risk Factors sections of such reports, as well as in subsequent filings with the SEC, each of which is on file with the SEC and available in the “Investors Relations” section of the Company’s website, www.colonialfed.com, under the heading “Recent SEC Filings.”
