~~Item~~The ~~5.07~~Merger ~~Submission~~Agreement has been unanimously approved by the boards of ~~Matters~~directors of BFC and Centre. The transaction is expected to aclose ~~Vote~~in the first quarter of ~~Security~~2026, ~~Holders~~subject to customary closing conditions discussed below.

~~Proposal~~Representations and 1Warranties. The Merger Agreement contains usual and customary representations and warranties that BFC and Centre made to each other as of specific dates. The assertions embodied in those representations and warranties were made solely for purposes of the contract between BFC and Centre and may be subject to important qualifications and limitations agreed to by the parties in connection with negotiating certain terms. Moreover, certain of the representations and warranties are subject to a contractual standard of materiality that may be different from what may be viewed as material to shareholders, and the representations and warranties may have been used to allocate risk between BFC and Centre rather than establishing matters of fact. For the foregoing reasons, no one should rely on such representations, warranties, covenants or other terms, provisions or conditions as statements of factual information regarding BFC or Centre at the time they were made or otherwise. The representations and warranties of the parties will not survive the closing.

~~The~~Covenants; No ~~proposal~~Solicitation. ~~was~~Each party also has agreed to ~~elect~~customary ascovenants, ~~directors~~including, among others, covenants relating to the ~~three~~conduct of its business during the interim period between the execution of the Merger Agreement and the consummation of the Merger.

In the event that Centre receives a proposal with respect to ~~serve~~an ~~until~~alternative acquisition transaction that the ~~2028~~Centre ~~Annual~~board ~~Meeting~~of directors determines is superior to the Merger, BFC will have an opportunity to match the terms of ~~Shareholders~~such proposal, subject to certain requirements.

Cautionary Statements Regarding Forward-Looking Information.

This Current Report contains “forward-looking statements” as defined in the Private Securities Litigation Reform Act of 1995. In general, forward-looking statements usually use words such as “may,” “believe,” “expect,” “anticipate,” “intend,” “should,” “plan,” “estimate,” “predict,” “continue” and “potential” or the negative of these terms or other comparable terminology, including statements related to the expected timing of the closing of the Merger, the expected returns and other benefits of the Merger to shareholders, expected improvement in operating efficiency resulting from the Merger, estimated expense reductions resulting from the transactions and the timing of achievement of such reductions, the impact on and timing of the recovery of the impact on tangible book value, and the effect of the Merger on BFC’s capital ratios. Forward-looking statements represent management’s beliefs, based upon information available at the time the statements are made, with regard to the matters addressed; they are not guarantees of future performance. Forward-looking statements are subject to numerous assumptions, risks and uncertainties that change over time and could cause actual results or financial condition to differ materially from those expressed in or implied by such statements.

Factors that could cause or contribute to such differences include, but are not limited to (1) the risk that the cost savings and any revenue synergies from the Merger may not be realized or take longer than anticipated to be realized, (2) disruption from the Merger with customers, suppliers, employee or other business partners, (3) the occurrence of any event, change or other circumstances that could give rise to the termination of the Merger Agreement, (4) the risk of successful integration of Centre’s business into BFC, (5) the failure to obtain the necessary approval by the shareholders of Centre, (6) the amount of the costs, fees, expenses and charges related to the Merger, (7) the ability of the parties to obtain required governmental approvals of the Merger, (8) reputational risk and the reaction of each of the companies’ customers, suppliers, employees or other business partners to the Merger, (9) the failure of the closing conditions in the Merger Agreement to be satisfied, or any unexpected delay in closing of the Merger, (10) the risk that the integration of Centre’s operations into the operations of BFC will be materially delayed or will be more costly or difficult than expected, (11) the possibility that the Merger may be more expensive to complete than anticipated, including as a result of unexpected factors or events, (12) the dilution caused by BFC’s issuance of additional shares of its common stock in the Merger transaction, and (13) general competitive, economic, political and market conditions. Other relevant risk factors may be detailed from time to time in BFC’s reports and filings with the SEC. Consequently, no forward-looking statement can be guaranteed. Neither BFC nor Centre undertakes any obligation to update or revise any forward-looking statements, whether as a result of new information, future events or otherwise. For any forward-looking statements made in this Current Report on Form 8-K, the exhibits hereto or any related documents, BFC and Centre claim protection of the safe harbor for forward-looking statements contained in the Private Securities Litigation Reform Act of 1995.
