As previously disclosed, on December 17, 2025, CVB Financial Corp., a California corporation ("CVBF"), and Heritage Commerce Corp, a California corporation ("Heritage"), entered into an Agreement and Plan of Reorganization and Merger (the "Reorganization Agreement"), pursuant to which Heritage will merge with and into CVBF, with CVBF continuing as the surviving corporation (the "Merger"). Promptly following the Merger, Heritage Bank of Commerce, a California banking corporation and wholly-owned subsidiary of Heritage ("Heritage Bank") will merge (the "Bank Merger" and with the "Merger", the "Mergers") with and into Citizens Business Bank, National Association, a national bank and wholly-owned subsidiary of CVBF ("Citizens"), with Citizens continuing as the surviving bank in the Bank Merger.

In connection with the proposed Merger, CVBF filed with the Securities and Exchange Commission (the "SEC") a registration statement on Form S-4 containing a joint proxy statement/prospectus, as amended, which was declared effective by the SEC on February 12, 2026. CVBF filed a definitive joint proxy statement/prospectus and Heritage filed a definitive proxy statement with the SEC, each dated February 12, 2026 (collectively, the "joint proxy statement/prospectus"), which CVBF and Heritage first mailed to their respective shareholders on or about February 13, 2026. Each of CVBF and Heritage will hold a special meeting of shareholders on March 26, 2026 to consider certain proposals related to the Reorganization Agreement as further described in the joint proxy statement/prospectus.

*Litigation Related to the Merger* 

Following the announcement of the Reorganization Agreement, as of the date of this Current Report on Form 8-K, three lawsuits challenging the Merger have been filed (each, a "Lawsuit" and, collectively, the "Lawsuits"). The first Lawsuit, captioned *Thompson v. Heritage Commerce Corp et al*. (Case No. 651158/2026), was filed in New York Supreme Court, New York County on February 25, 2026. The second Lawsuit, *Johnson v. Heritage Commerce Corp et al*. (Case No. 651177/2026), was filed in New York Supreme Court, New York County on February 26, 2026. The third Lawsuit, *Siegel v. Abate et al*. (Case No. 26CV488158), was filed in the Superior Court of California, County of Santa Clara on March 3, 2026. In addition, CVBF and Heritage have received demand letters from counsel representing purported shareholders of Heritage (the "Demand Letters" and, together with the Lawsuits, the "Matters"). The Matters each allege that, among other things, the joint proxy statement/prospectus contains certain disclosure deficiencies and/or incomplete information regarding the Merger.

CVBF and Heritage believe that the claims asserted in the Matters are without merit and supplemental disclosures are not required or necessary under applicable laws. However, in order to moot certain of the plaintiffs' disclosure claims in the Lawsuits and Demand Letters, to avoid the risk that the Matters delay or otherwise adversely affect the Merger, to minimize the costs, risks and uncertainties inherent in litigation, and to provide additional information to shareholders of CVBF and Heritage, and without admitting any liability or wrongdoing, CVBF and Heritage are supplementing the joint proxy statement/prospectus as described in this Current Report on Form 8-K. 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. To the contrary, CVBF and Heritage specifically deny all allegations in the Matters that any additional disclosure was or is required.

To the extent that information in the below supplemental disclosures, differs from, or updates information contained in, the joint proxy statement/prospectus, the information in the below supplemental disclosures will supersede or supplement the information in the joint proxy statement/prospectus. Except as otherwise described in the below supplemental disclosures or the documents referred to, contained in or incorporated by reference herein, the joint proxy statement/prospectus, the annexes to the joint proxy statement/prospectus and the documents referred to, contained in or incorporated by reference in the joint proxy statement/prospectus are not otherwise modified, supplemented or amended.

12. *The section of the joint proxy statement/prospectus titled "The Merger — Interests of Heritage Directors and Executive Officers in the Merger" starting on page 91 is hereby amended as follows:* 

For all purposes under the section of the joint proxy statement/prospectus titled "The Merger — Interests of Heritage Directors and Executive Officers in the Merger," Seth Fonti (Executive Vice President and Chief Financial Officer of Heritage) shall be treated as a named executive officer of Heritage, and Heritage shall be treated as having four executive officers who are not named executive officers: Messrs. Edmonds-Waters and Shu, and Mses. Sabnani and Tam. Specifically, the second to last sentence in the paragraph after this section title on page 91 is hereby amended as follows: Heritage has five <u>four</u> executive officers who are not named executive officers: Messrs. Fonti, Edmonds-Waters and Shu and Mses. Sabnani and Tam.

13. *The second bullet of the section of the joint proxy statement/prospectus titled "The Merger — Interests of Heritage Directors and Executive Officers in the Merger — Certain Assumptions" on page 91 is hereby amended and restated as follows:* 

• the effective time of the merger as referenced in this section occurs on January 25, 2026 <u>March</u> <u>13, 2026</u>, which is the assumed date of the effective time of the merger solely for purposes of the disclosure in this section (the "Assumed Closing Date"); and

No Heritage non-employee directors or executive officers hold outstanding and unvested Heritage option awards. The aggregate number of unvested Heritage restricted stock awards held by the seven current Heritage non-employee directors (not including Mr. DiNapoli, who no longer holds any unvested Heritage restricted stock awards following his scheduled retirement) is 39,698. If the closing does not occur prior to March 2026, Heritage non-employee directors will be granted their ordinary course annual award of Heritage restricted stock, with an estimated aggregate grant date fair value of $385,000, which will vest at closing (or, at Heritage's election, cash awards in lieu thereof) <u>30,970</u>. For an estimate of the amounts that would be realized by each of Heritage's named executive officers on the Assumed Closing Date in respect of their Heritage equity awards that are outstanding and unvested on such date, see the section below entitled "—*Quantification of Potential Payments and Benefits to Heritage's Named Executive Officers in Connection with the Merger*." The aggregate number of shares of Heritage common stock underlying unvested Heritage RSU Awards, Heritage PSU Awards and Heritage restricted stock awards held by the five <u>four</u> executive officers who are not named executive officers is 173,473 <u>178,329</u> based on the assumptions described herein.

15. *The section of the joint proxy statement/prospectus titled "The Merger — Interests of Heritage Directors and Executive Officers in the Merger — Heritage Employment Agreements with Executive Officers" is hereby amended as follows:* 

#### Amending the second paragraph of such section on page 93:
See the section below entitled "—*Quantification of Potential Payments and Benefits to Heritage's Named Executive Officers in Connection with the Merger*" for the estimated amounts that each of Heritage's named executive officers would receive upon a qualifying termination of employment following the effective time. Based on the assumptions described above under "*— Certain Assumptions*," the estimated aggregate value of the severance benefits that the four executive officers with employment agreements who are not named executive officers (i.e., Messrs. Shu and Edmonds-Waters and Mses. Sabnani and Tam) would receive under their employment agreements, <u>or, in the case of Ms.</u> <u>Tam, under Heritage's existing severance policy,</u> upon a qualifying termination of employment following the effective time is $5,609,692 <u>$3,918,678</u> (assuming no reduction in payments or benefits for purposes of the excise tax under Section 4999 of the Code).

Ms. Tam has been allocated a retention award of $300,000 , which will vest in full on the date that is 30 days following systems conversion, subject to Ms. Tam's continued employment through such date. If Ms. Tam's employment is terminated without cause following the effective time, or due to Ms. Tam's death or disability following the effective time, Ms. Tam's retention award will immediately vest, subject to the effectiveness of a customary release of claims <u>pursuant to the employment offer letter with Citizens, as further described under the section titled "</u>*The Merger — Interests of Heritage Directors and Executive Officers in the Merger — Potential Employment Arrangements with CVBF"*<u>.</u>

17. *The fourth paragraph on page 95 of the joint proxy statement/prospectus under the Section "The Merger — Interests of Heritage Directors and Executive Officers in the Merger — Potential Employment Arrangements with CVBF" is hereby deleted and replaced in its entirety with the following disclosure:* 

<u>Citizens and Heritage Bank have jointly informed Messrs. Edmonds-Waters, Fonti and Sa and Mses. Just and Sabnani that their respective positions with Heritage and Heritage Bank will be eliminated in connection with the closing of the merger. As a result thereof, such executive officers will receive the severance payments and benefits to which they are entitled pursuant to their existing employment agreements with Heritage, as described above under the section titled "— Heritage Employment Agreements with Executive Officers", less applicable withholdings, and subject to the execution of a waiver and release agreement.</u> 

<u>With respect to Ms. Tam, Citizens and Heritage Bank have jointly offered Ms. Tam employment with the surviving bank for an interim period post-closing until July 3, 2026 (which is subject to further extension) (the "interim employment period"). During the interim employment period, Ms. Tam will serve as Senior Vice President and Conversion & Integration Lead for the surviving bank and will receive compensation paid on a pro rata basis based on an annualized base salary of $270,000. Upon the conclusion of the interim employment period or an earlier qualifying termination of employment, Ms. Tam will be eligible to receive (i) the severance payments and benefits pursuant to Heritage's existing employee severance policy, and (ii) a retention bonus of $300,000, in each case, less applicable tax withholdings, and subject to the execution of a waiver and release agreement.</u>

18. *The tables and accompanying footnotes on pages 96 through 98 of the joint proxy statement/prospectus in the section titled "The Merger — Interests of Heritage Directors and Executive Officers in the Merger — Quantification of Potential Payments and Benefits to Heritage's Named Executive Officers in Connection with the Merger" are hereby amended and restated as follows:*

| (1). | *Named Executive Officers*. Deborah Reuter retired as Executive Vice President and Chief Risk Officer effective as of January 5, 2026, and Ms. Reuter will continue as a non-executive employee advisor until March 31, 2026, unless otherwise extended by mutual agreement. Ms. Reuter is a named executive officer for purposes of this disclosure but is not entitled to receive any compensation in connection with the merger. Lawrence McGovern (Former Executive Vice President and Chief Financial Officer), who terminated employment on February 14, 2025, is also a named executive officer for purposes of this disclosure but is not entitled to receive any compensation in connection with the merger.  |

---

(2). *Cash*. Consists of the following:

*Cash Severance*. A lump sum cash severance payment in respect of the executive's employment agreement with Heritage equal to 2.75 times (for Mr. Jones) or 2 times (for the other executives) the sum of the executive's (i) current annual base salary and (ii) average annual bonus or incentive compensation paid to or earned by the executive over the prior three-year period. The payments under the Heritage employment agreements are "double-trigger," meaning that both a change in control of Heritage and a qualifying termination of employment must occur prior to the cash severance payments described above being made to any such named executive officer, but as described above, such amounts may be paid by Heritage immediately prior to the effective time on a "single-trigger" basis, without regard to termination of employment (other than as described above for Messrs. Jones and Warford). As noted above, Citizens and Heritage Bank have jointly notified Messrs. Fonti and Sa and Ms. Just that their respective positions will be eliminated following the effective time, and such executives will be entitled to receive such cash severance payments upon termination of employment (to the extent not paid by Heritage immediately prior to the effective time).

*2026 Prorated Annual Bonus*. Pursuant to the merger agreement, each named executive officer would be eligible to receive a prorated annual bonus under Heritage's cash incentive plans and programs in respect of the 2026 performance year through the Assumed Closing Date, as described above in the section entitled "*—2026 Annual Bonus Opportunity*." The prorated annual bonus is "double-trigger" and would only be payable prior to the date on which CVBF pays bonuses in 2027 if the executive's employment is terminated by CVBF without cause, as described above in the section entitled "—*2026 Annual Bonus Opportunity*." For purposes of the following table, prorated annual bonuses are calculated assuming the target level of achievement. The estimated amount of each such payment is shown in the following table:

| (3). | *Equity*. The amounts in this column represent the value of the accelerated vesting of Heritage restricted stock awards, Heritage RSU Awards and Heritage PSU Awards, in each case outstanding as of the Assumed Closing Date and calculated based on the Assumed Stock Price (in the case of Ms. Just and Messrs. Sa and Warford, not including awards that previously vested in connection with mitigation actions under Section 280G of the Code, as described above; Messrs. Jones and Fonti did not have awards vested for such purpose). For Heritage PSU Awards, such amounts are based on assumed achievement of target levels of performance, per the merger agreement. These amounts are "single-trigger" and will be paid in connection with the effective time pursuant to the terms of the merger agreement. For further details regarding the treatment of Heritage equity awards in connection with the Merger, see the section above entitled "*—Treatment of Outstanding Heritage Equity Awards*."  |

Mr. Warford holds Heritage option awards, all of which are fully vested as of the date hereof and therefore not reflected in the table below.

| (4). | *Pension/NQDC*. Consists of an amount equal to 100% of the accrued liability balance under the SERP for Mr. Jones calculated as if Mr. Jones had attained age 65 on the Assumed Closing Date ($708714), less the amount Mr. Jones would be eligible to receive under the SERP on a voluntary separation from service prior to age 65 absent a change in control ($214584). This amount is "double-trigger," meaning that both a change in control of Heritage and Mr. Jones's qualifying termination of employment must occur prior to the incremental benefit described above being paid to Mr. Jones, and becomes payable only if Mr. Jones experiences an involuntary separation from service for any reason other than for cause within two years following the effective time.  |

| (5). | *Perquisites/Benefits*. Consists of continuation of medical, dental and vision coverage at the employer's cost for a period of 24 months and, for Mr. Jones, $5,000 in respect of outplacement services. These amounts are "double-trigger," meaning that both a change in control of Heritage and a qualifying termination of employment must occur within the period beginning 120 days prior to the date of the definitive merger agreement and ending 24 months following a change in control (including the merger) prior to such amounts being paid to any such named executive officer, in each case, as described above in the section entitled "—*Heritage Employment Agreements with Executive Officers*." As described above, Mr. Jones and Mr. Warford are each currently expected to continue in employment with CVBF and Citizens following the merger, in which case they would not receive these enhanced amounts.  |
