Item 2.01 Completion of Acquisition or Disposition of Assets. Effective April 17, 2026 (the “Closing Date”), CVB Financial Corp., a California corporation (“CVBF” or the “Company”) completed its previously announced acquisition of Heritage Commerce Corp, a California corporation (“Heritage”), in accordance with the terms and conditions of that certain Agreement and Plan of Reorganization and Merger, dated as of December 17, 2025, by and between CVBF and Heritage (the “Merger Agreement”). On the Closing Date, Heritage merged with and into CVBF, with CVBF being the surviving entity (the “Merger”). Immediately thereafter, Heritage’s wholly-owned banking subsidiary, Heritage Bank of Commerce, a California banking corporation (“Heritage Bank”) merged with and into CVBF’s wholly-owned banking subsidiary, Citizens Business Bank, National Association (“Citizens”), with Citizens being the surviving bank (the “Bank Merger” and with the “Merger”, the “Mergers”) Pursuant to the Merger Agreement, each share of Heritage’s common stock outstanding immediately prior to the effective time of the Merger (the “Effective Time”) was cancelled and converted into the right to receive 0.65 shares of CVBF’s common stock (the “Merger Consideration,” and such exchange ratio, the “Exchange Ratio”). In addition, at the Effective Time, (i) each unexercised and outstanding Heritage option award, whether vested or unvested, was cashed out and option holders received per option share the positive excess, if any, of (a) the applicable cashout price of such Heritage option award (calculated as an amount, rounded to the nearest cent, equal to the product of (x) $19.28, which was the 20-day volume weighted average closing price of a share of CVBF common stock as of the fifth business day prior to the Closing Date, and (y) the Exchange Ratio), over (b) the exercise price per option share, less applicable withholding taxes; (ii) Heritage restricted stock awards, Heritage restricted stock unit awards, interim Heritage restricted stock unit awards granted to Heritage employees in March 2026 (the “Interim Heritage RSUs”) and held by Heritage employees who are not continuing with CVBF, and Heritage performance-based restricted stock unit awards outstanding as of the Effective Time were accelerated and vested in full at the Effective Time (in the case of any performance-based restricted stock unit award, at the target number of shares subject to such award), and such Heritage stock awards, net of applicable withholding taxes, were converted into and became exchanged for the Merger Consideration; (iii) outstanding Interim Heritage RSUs held by Heritage employees who are continuing with CVBF as of the Effective Time, were substituted with CVBF restricted stock unit awards on substantially the same terms and conditions as such Interim Heritage RSUs, as adjusted for the Exchange Ratio, under CVBF’s 2018 Equity Incentive Plan, as amended. As a result of the Merger, CVBF issued approximately 41 million shares of CVBF common stock to former Heritage shareholders. The issuance of shares of CVBF common stock in connection with the Merger was registered under the Securities Act of 1933, as amended (the “Securities Act”), pursuant to a registration statement on Form S-4 (File No. 333-293102) filed by CVBF with the Securities and Exchange Commission (the “Commission”) and declared effective on February 12, 2026. The foregoing description of the transactions contemplated by the Merger Agreement does not purport to be complete and is qualified in its entirety by reference to the full text of the Merger Agreement, which is filed as Exhibit 2.1 to this Current Report on Form 8-K and incorporated herein by reference.
