CVB Financial and Heritage Commerce Corp (HTBK) outline proposed bank merger

Rhea-AI Filing Summary

CVB Financial Corp. and Heritage Commerce Corp. describe a proposed merger under an Agreement and Plan of Reorganization and Merger dated December 17, 2025. The communication focuses on forward-looking statements about potential benefits, future financial and operating results, and the expected timing of completion, while emphasizing that many economic, regulatory, operational, and integration risks could cause actual outcomes to differ.

CVB Financial plans to file a Form S-4 registration statement that will include a joint proxy statement and prospectus so shareholders of both companies can consider and vote on the merger. The text explains how investors can obtain these SEC documents for free and notes that directors and executive officers of both companies may be deemed participants in the proxy solicitation, directing readers to existing SEC filings for detailed information about their holdings and risk factors.

Disclosure outlines a planned bank merger and its risks, with no financial terms here.

The communication explains that CVB Financial Corp. and Heritage Commerce Corp. have entered into a merger agreement and plan a stockholder vote supported by a future Form S-4 with a joint proxy statement and prospectus. The emphasis is on legal and procedural transparency rather than deal economics, which are not described in this excerpt.

Most of the text is a detailed caution about forward-looking statements, listing numerous macro, regulatory, credit, technology, integration, and market risks that could affect the combined company and the merger’s anticipated benefits. It also highlights conditions such as the need for regulatory and shareholder approvals and the possibility that the agreement could be terminated under certain circumstances.

The notice points investors to existing Form 10-Ks, 10-Qs, proxy statements and future S-4 materials for specific risk factors and information on directors’ and officers’ shareholdings. Overall, this looks like a standard communication accompanying a bank merger announcement, important as context but not sufficient on its own to assess the transaction’s financial impact.

(“CVBF”) and Heritage Commerce Corp (“Heritage”), the expected timing of completion of the transaction, and other statements that are not historical facts. Such statements are subject to numerous assumptions, risks, estimates, uncertainties and other important factors that may change over time and could cause actual results to differ materially from any results, performance, or events expressed or implied by such forward-looking statements, including as a result of the factors referenced below. Statements that do not describe historical or current facts, including statements about beliefs and expectations, are forward-looking statements.
