RECENT DEVELOPMENTS

On September 2, 2025, Mechanics Bancorp (formerly known as HomeStreet, Inc.), a Washington corporation, consummated a merger (the “Merger”) pursuant to the terms of an Agreement and Plan of Merger, dated as of March 28, 2025 (as amended, the “Merger Agreement”), by and among the Company, HomeStreet Bank, a Washington state-chartered commercial bank and wholly-owned subsidiary of the Company, and Mechanics Bank, a California banking corporation. At the effective time of the Merger (the “Effective Time”), HomeStreet Bank merged with and into Mechanics Bank, with Mechanics Bank surviving the Merger and becoming a wholly-owned subsidiary of the Company, and the Company’s business became primarily the business conducted by Mechanics Bank.

In accordance with the terms and subject to the conditions set forth in the Merger Agreement, at the Effective Time, each share of common stock, par value $50 per share, of Mechanics Bank designated as voting common stock issued and outstanding immediately prior to the Effective Time, subject to certain exceptions, was converted into the right to receive 3,301.0920 shares of Class A common stock, no par value, of the Company (the “Class A common stock”). All existing shares of Company common stock held by legacy Company shareholders were redesignated as Class A common stock pursuant to an amendment to the Company’s articles of incorporation (the “Articles Amendment”) that was adopted in connection with the Merger. Further, in accordance with the terms and subject to the conditions set forth in the Merger Agreement, at the Effective Time, each share of common stock, par value $50 per share, of Mechanics Bank designated as non-voting common stock issued and outstanding immediately prior to the Effective Time was converted into the right to receive 330.1092 shares of Class B common stock, no par value, of the Company (the “Class B common stock,” and together with the Class A common stock, the “Company common stock”), which was newly created pursuant to the Articles Amendment. Each holder of Mechanics Bank common stock who would have been entitled to receive a fraction of a share of Company common stock (after taking into account all shares of Mechanics Bank common stock held by such holder) instead received cash in lieu of such fractional share in accordance with the terms of the Merger Agreement.

The aggregate number of shares of (i) Class A common stock that the Company issued to Mechanics Bank shareholders at the Effective Time was 200,901,384, resulting in approximately 219,822,191 shares of Class A common stock outstanding immediately following the Effective Time, and (ii) Class B common stock that the Company issued to Mechanics Bank shareholders at the Effective Time was 1,114,448, resulting in 1,114,448 shares of Class B common stock outstanding immediately following the Effective Time. As a result, immediately following the Effective Time, (1) legacy Mechanics Bank shareholders owned approximately 91.7% of the Company on an economic basis and 91.3% of the voting power of the Company and (2) legacy Company shareholders owned approximately 8.3% of the Company on an economic basis and 8.7% of the voting power of the Company.

Following the Merger, EB Acquisition Company LLC, EB Acquisition Company II LLC, Ford Financial Fund II, L.P. and Ford Financial Fund III, L.P. (the “Ford Entities”) controlled approximately 77.7% of the voting power of the Company, and accordingly, the Company became a “controlled company” for purposes of the Nasdaq listing rules.

At the Effective Time, the Company’s board of directors was reconstituted such that it was composed of the members of the board of directors of Mechanics Bank immediately prior to the Merger, and one member of the legacy HomeStreet, Inc. board of directors, who was designated to be Nancy D. Pellegrino. In addition, C.J. Johnson was appointed the President and Chief Executive Officer, Nathan Duda was appointed the Chief Financial Officer, and other executive officers of Mechanics Bank immediately prior to the Merger were appointed into executive officer roles with the Company. The biographies of the current members of our Board of Directors (“Board”) and executive officers are set forth in this Proxy Statement.

For purposes of the election of directors, abstentions and broker non-votes will not be counted as votes cast and will have no effect on the result of the vote, although they will be considered present for purposes of determining a quorum. Under the applicable rules of the New York Stock Exchange, a broker or other nominee does not have the authority to vote for the director nominees in the absence of instructions from the beneficial owner of the relevant shares. Shareholders may not cumulate votes in the election of directors.

THE BOARD UNANIMOUSLY RECOMMENDS VOTING “FOR” THE ELECTION OF EACH OF THE EIGHT DIRECTOR NOMINEES.

CORPORATE GOVERNANCE

General

As a bank holding company, we believe it is important to foster an operating environment that articulates a strong focus on compliance and ethical standards, and the Board sets this tone from the top. The Board is actively engaged in designing, monitoring and enforcing compliance with high governance standards. We discuss our most important corporate governance policies and practices below.

Board Leadership Structure

The Board believes that it is in the best interests of the Company and its shareholders for the Board to retain discretion to determine whether to separate the roles of Chairman of the Board and Chief Executive Officer based on the business and governance needs and the membership of our Board. The Board has determined separate positions of Chairman and Chief Executive Officer provides the appropriate leadership structure for us at this time, particularly since the separation of those two positions enables our Chief Executive Officer to focus on running the Company’s daily operations and executing the Board’s strategic plan, while the Executive Chairman primarily focuses on governance, strategy and high-level oversight.

Risk Oversight

The Board, together with its committees and senior management, has oversight of our risk management framework and is responsible for helping to ensure that our risks are managed in a sound manner. The Board’s principal responsibility in this area is to oversee an enterprise-wide approach to risk management and ensure that sufficient resources, with appropriate technical and managerial skills, are provided throughout the Company to identify, assess and facilitate processes and practices to address material risks.

In addition, the Board has delegated oversight of certain categories of risk to the Audit Committee, the Risk Committee, the Compensation Committee and the N&G Committee. The Audit Committee reviews and discusses with management significant financial and non-financial risk exposures and the steps management has taken to monitor, control and report such exposures. The Risk Committee oversees and assesses the adequacy of the Company’s risk management framework, monitors compliance with the Board-approved risk appetite measures and other key risk measures and oversees management of key risks not overseen by other committees of the Board, including legal, compliance and operational risks, information technology, information security and cybersecurity risks. The Compensation Committee oversees management of risks relating to the Company’s compensation plans and programs. The N&G Committee oversees management of risks relating to the Company’s nominating and corporate governance functions. The Audit Committee, the Risk Committee, the Compensation Committee and the N&G Committee report to the Board as appropriate on matters that involve specific areas of risk that each committee oversees, and with the Board, each committee periodically discusses with management the Company’s policies with respect to risk assessment and risk management. The board of directors of our primary subsidiary, Mechanics Bank, also oversees certain risks specific to Mechanics Bank, including credit, liquidity, interest rate and price risk, through various committees of the Mechanics Bank board.

Board Performance

The Board of Directors conducts an evaluation of performance with a view to improving effectiveness of the Board and its committees. In addition, the full Board of Directors reviews annually the qualifications and effectiveness of its committees and its members.

Controlled Company Status

The Ford Entities control approximately 77.6% of the voting power of the Company. As a result, the Company is a “controlled company” for purposes of Nasdaq listing rules and qualifies for exemptions from certain governance standards that would otherwise be applicable. Under Nasdaq listing rules, a company of which more than 50% of the voting power is held by an individual, a group or another company is a “controlled company” and is exempt from certain corporate governance requirements that would otherwise require a company to have: (i) a nominating committee comprised solely of independent directors or select or recommend director nominees by a majority of the independent directors and (ii) a compensation committee comprised solely of independent directors. The Company relies on these exemptions. The controlled company exemption does not modify the independence requirements for the audit committee, and the Company complies with the requirements of Nasdaq with respect thereto.

Director Independence

The Board has affirmatively determined that seven of the eight nominees for election as directors at the Annual Meeting have no material relationship with the Company (either directly or as a partner, stockholder or officer of an organization that has a relationship with the Company) and are independent within the meaning of the director independence requirements of the listing standards of Nasdaq. The independent directors are E. Michael Downer, Patricia Cochran, Adrienne Y. Crowe, Douglas Downer, Nancy D. Pellegrino, Kenneth D. Russell, and Jon R. Wilcox. In addition, each member of the Audit Committee has been affirmatively determined by the Board to be independent under the rules promulgated by the Securities and Exchange Commission and Nasdaq listing standards for the purposes of Audit Committee service. Carl B. Webb is not independent under the Nasdaq listing standards. Mr. Webb is employed by GJF Management II, LLC, an affiliate of Gerald J. Ford, which the Bank has a Bank Services Agreement with.

In addition, all of our former directors who served during 2025 prior to the Merger were also affirmatively determined to have no material relationship with the Company (either directly or as a partner, stockholder or officer of an organization that has a relationship with the Company) and were independent within the meaning of the director independence requirements of the listing standards of Nasdaq, other than Mark K. Mason, who was the former President and Chief Executive Officer of HomeStreet, Inc.

In conducting its annual review of director independence, the Board considered transactions and relationships between each director or any member of his or her immediate family and the Company.

Corporate Governance Principles

The Company has adopted Corporate Governance Principles to promote the effective functioning of the Board and its committees, promote the interest of stockholders, and further the Company’s commitment to best practices in corporate governance. The Corporate Governance Principles can be found on our investor relations website: https://ir.mechanicsbank.com.

Code of Conduct

The Board has established a code of ethics as defined under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), which applies to all directors, officers and employees of the Company and its subsidiaries, including our principal executive officer, principal financial officer and principal accounting officer or controller. A copy of our Code of Conduct (“Code of Conduct”) can be found on our investor relations website: https://ir.mechanicsbank.com. We will post on our website any amendments to, or waivers (with respect to our principal executive officer, principal financial officer and principal accounting officer or controller) from, this Code of Conduct within four business days of any such amendment or waiver and, to the extent required by the listing standards of Nasdaq, by filing a Current Report on Form 8-K with the SEC disclosing such information. Among other things, the Code of Conduct addresses the following principles:

•maintaining accurate and complete records;

•avoiding conflicts of interest;

•complying with laws and regulations;

•prohibiting insider trading;

•avoiding questionable gifts or favors;

•treating others in an ethical manner;

•maintaining integrity of consultants, agents and representatives; and

•protecting proprietary information and proper use of assets.

Employee Compensation Risks

The Company’s management and the Compensation Committee have assessed the risks associated with our compensation policies and practices for all employees, including non-executive officers. Based on the results of this assessment, we do not believe that our compensation policies and practices for any employees, including non-executive officers, create excessive risks or risks that are reasonably likely to have a material adverse effect on the Company.

Board Meetings and Committees

Pre-Merger

From January 1, 2025 through September 1, 2025, the board of directors of Legacy HomeStreet held 14 meetings. From January 1, 2025 through September 1, 2025, there were six meetings held by the Audit Committee; three meetings held by the Enterprise Risk Committee; three meetings held by the Compensation Committee; two meetings held by the N&G Committee; and two meetings held by the Finance Committee.

Post-Merger

From September 2, 2025 through December 31, 2025, the Board held 2 meetings. From September 2, 2025 through December 31, 2025, there were two meetings held by the Audit Committee; one meeting held by the Risk Committee; and two meetings held by the Compensation Committee.

During the fiscal year 2025, each of our directors attended or participated in at least 75% or more of the aggregate of the total number of meetings of the Board and the total number of meetings held by all committees of the Board on which that director served.

The Board has four standing committees: the Audit Committee, the Risk Committee, the Compensation Committee and the N&G Committee. The following table indicates the current membership of each committee.

The Board has determined that Patricia Cochran is qualified as an “audit committee financial expert.”

The Audit Committee helps our Board ensure the integrity of our financial statements, the qualifications and independence of our independent registered public accounting firm and the performance of our internal audit function and independent registered public accounting firm. Our Board has adopted a written Audit Committee charter that meets the requirements of the applicable Exchange Act rules and the applicable Nasdaq corporate governance standards. A copy of this charter can be found on our investor relations website: https://ir.mechanicsbank.com. Among other things, this charter requires the Audit Committee to:

The Audit Committee of the Company meets jointly with the Audit Committee of Mechanics Bank.

Risk Committee

The Risk Committee oversees and assesses the adequacy of the Company’s tolerance and management of key enterprise-wide risks, including credit, interest rate, liquidity, market, capital, operational, technology/information security, compliance, legal, strategic and reputational risks.

Deferred Compensation Agreements

In December 2024, legacy HomeStreet entered into deferred compensation agreements (the “Agreements”) with Mark Mason, former Chief Executive Officer of legacy HomeStreet, John Michel, former Chief Financial Officer of legacy HomeStreet and William Endresen, former Executive Vice President, Commercial Real Estate of HomeStreet Bank in lieu of equity awards they would have been granted under legacy HomeStreet’s Amended and Restated 2014 Executive Incentive Plan (the “Plan”) which expired in March 2024.

Legacy HomeStreet entered into deferred compensation agreements, effective as of January 1, 2025, with Mr. Mason, Mr. Michel, and Mr. Endresen. Under their respective agreements, Mr. Mason, Mr. Michel, and Mr. Endresen were entitled to receive $855,088, $293,638, and $215,150, respectively, with 50% of the amount, for each executive, vesting in equal installments on each of the next three anniversaries of the effective date his agreement (the “Annual Vesting Amount”) and the remaining 50% vesting in full on the third anniversary of the effective date of his agreement (the “Cliff Vesting Amount”), subject, in each case, to the executive’s continuous service through the applicable vesting date.

If the executive’s service terminated due to death or disability, the executive was deemed to have vested in a pro rata portion of the Annual Vesting Amount and the Cliff Vesting Amount as of the date of such termination. If the executive’s service terminated on or prior to January 1, 2028 as a result of the executive’s retirement on or after age 65, the executive was to vest in a pro rata portion of the deferred compensation amount.

If a “Change in Control” (as defined in the Agreements) occurred prior to January 1, 2028, and the executive’s service was terminated without “cause” (as defined in the Agreements), in connection with the Change in Control or within 12 months following such Change of Control, then the deferred compensation amount was deemed to have vested in full on the effective date of the termination of the executive’s service. If the executive’s service terminated at the initiation of the executive for “Good Reason” (as defined in the Agreements), the deferred compensation amount for that executive was to be deemed vested in full on the effective date of the termination of the executive’s service.

The preceding three paragraphs are a summary of the material terms of the deferred compensation agreements, and the summary does not purport to be complete. A copy of the form of the deferred compensation agreements applicable to Messrs. Michel, Endresen and Mason is filed as Exhibit 10.13 to the fiscal year end 2025 Form 10-K.

Mechanics Bancorp CEO Compensation

Pursuant to that certain Bank Services Agreement, as amended, between Mechanics Bank and GJF Management, the Company compensates GJF Management up to $10 million per annum for services rendered by GJF Management, and GJF Management compensates certain personnel of Ford Management II, L.P. and Ford Management III, L.P., including Mr. Johnson, for their services to the Company. See the section entitled “Certain Relationships And Related Transactions” for more information on the Mechanics Bank Services Agreement.

Bonus

The Company approved a one-time special bonus to Mr. Duda in the amount of $177,800 and to Mr. Givans in the amount of $116,400 in connection with the completion of the Merger. Mr. Duda and Mr. Givans also each received a $100,000 discretionary bonus.

Annual Cash Incentives

The Company’s Annual Incentive Plan provides for annual performance-based cash bonuses to certain key employees selected by the Compensation Committee for participation. The Annual Incentive Plan is designed to reward executives whose performance during the fiscal year enabled the Company to achieve favorable business results and to assist the Company in attracting and retaining executives. A participant may receive a cash bonus under the Annual Incentive Plan based on the attainment, during each performance period, of certain individual and corporate performance objectives that are established by the Compensation Committee in support of the Company’s business strategy. These performance objectives may be based on one or more performance criteria.

The performance objectives may be applied with respect to Mechanics Bancorp or any one or more of its divisions, business units or business segments and may be applied to performance relative to a market index or a group of other

companies. The Compensation Committee may adjust the performance goals applicable to any awards to reflect any unusual or non-recurring events.

Participation in the Annual Incentive Plan does not guarantee the payment of an award. All awards payable pursuant to the Annual Incentive Plan are discretionary and subject to approval by the Compensation Committee. After the performance period ends, the Compensation Committee determines the payment amount, if any, of individual awards based on the achievement of the performance objectives. The payment of a cash bonus to a participant for a performance period is conditioned upon the participant’s active employment on the date that the final awards are paid. Mechanics Bancorp may amend or terminate the Annual Incentive Plan at any time.

Based upon financial and individual performance measures and the Compensation Committee’s discretion, the 2025 annual cash incentive payments were awarded as follows:

2025 Annual Incentive Plan (1)


NEO	Salary ($)	Target %	Factors			Performance			2025 Payout
			Bank %	Business Unit %	Discretionary %	Bank %	Business Unit %	Discretionary %	Bank ($)	Business Unit ($)	Discretionary ($)	Total ($)

Nathan Duda	600,000	50	80	—	20	100	—	100	240,000	—	60,000	300,000
Scott Givans	525,000	50	80	—	20	100	—	100	210,000	—	52,500	262,500

(1)Based upon 2025 performance but paid in March 2026.

Mr. Mason and Mr. Michel, were eligible to participate in the legacy HomeStreet, Inc. Annual Incentive Plan, which provided an opportunity to receive an annual incentive award that was contingent on achieving pre-defined annual corporate objectives, as well as individual goals which target their respective areas of responsibility. Mr. Endresen was eligible for annual incentive awards under a separate arrangement, which provided for incentive payout opportunities based on business unit performance results. Mr. Mason and Mr. Michel each met their corporate objectives and individual goals, and received incentive awards for performance in 2025. Mr. Endresen received incentive awards under a separate agreement for his performance in 2025. As a result of the resignations of the former executives in connection with the completion of the Merger, the former executives received pro-rated incentive awards pursuant to the foregoing for performance in 2025.

Long-Term Incentives

Our long-term incentive compensation consists of a combination of time-based restricted share units (“RSUs”) and performance share units (“PSUs”) that are granted under the Mechanics Bancorp 2025 Equity Incentive Plan (the “2025 Plan”).

In 2025, the Company granted long-term incentive awards consisting of RSUs, as approved by the Compensation Committee. The value of the equity awards determined by the Compensation Committee was based on a target value as a percentage of base salary. The Compensation Committee determines the target by reviewing Peer Group data and appropriate market data relevant to the banking industry and sets targets at levels intended to create a meaningful opportunity for reward predicated on increasing shareholder value. In addition to considering competitive market data, the Compensation Committee also considers an individual’s performance history, experience, an individual’s potential for future advancement and promotions, the CEO’s recommendations for awards other than his own, and the value of existing vested and unvested outstanding equity awards. The relative weight given to each of these factors varies among individuals at the Compensation Committee’s discretion.

The RSUs are awarded annually as part of our long-term incentive plan and vest incrementally in four annual installments from the grant date. In each case, the vesting of the award is contingent on the NEO’s employment with the Company not having been terminated for any reason other than retirement, death or disability prior to the applicable vesting date.

PSUs are earned and vested based on achieving a specified company performance result and continued employment over the three-year performance period. In each case, the vesting of the award is also contingent on the NEO’s employment with the Company not having been terminated for any reason other than retirement, death or disability prior to the date the Compensation Committee certifies the achievement of the performance goal for the relevant performance period.

None of the former executives received any RSU or PSU awards in 2025. Following the Merger, Messrs. Duda and Givans received 21,818 and 19,091 RSUs in 2025, respectively, with a grant date fair value of $299,998 and $262,501, respectively.

Nonqualified Deferred Compensation Plan

Each of our NEOs is eligible to participate in the Mechanics Bancorp Deferred Compensation Plan (“Deferred Compensation Plan”), which is a nonqualified retirement savings plan that allows for deferrals above the IRS limits on qualified plans.

Participants may elect to defer up to 85% of base salary and up to 100% of certain eligible incentive awards. The Company may, at its discretion, make Company contributions to the Deferred Compensation Plan on behalf of any participant. Participants may generally elect to receive their distribution in a lump sum following the participant’s retirement or over a period of up to 10 years. Mr. Givans participates in the Deferred Compensation Plan.

OTHER PRACTICES, POLICIES AND GUIDELINES

Recoupment of Incentive Compensation

The Board has adopted an Incentive Compensation Recoupment Policy. Under this policy, if any of our executive officers receive incentive compensation as a result of our achievement of financial results measured on the basis of consolidated financial statements that are required to be restated, the Company generally will be obligated to recoup from those executive officers the amount by which the incentive compensation they had received based on those consolidated financial statements or the satisfaction of those metrics exceeds the incentive compensation they would have received had such incentive compensation been determined on the basis of the restated consolidated financial statements or revised metric results (“excess compensation”). This policy provides for the recoupment of excessive compensation paid to or received by any executive officer during the three years immediately preceding the accounting restatement. This policy further provides that the Company may seek recovery of any gain realized on the vesting, exercise, settlement, sale, transfer or other disposition of any equity-based awards. This policy is intended to comply with Section 10D of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), Rule 10-D-1 of the Exchange Act, Nasdaq Listing Rule 5608 and other regulations, rules and guidance of the SEC. The description of the Incentive Compensation Recoupment Policy above is qualified in its entirety by the text of the policy, which can be found as Exhibit 97.1 to our Annual Report on Form 10-K for the year ended December 31, 2025.

Hedging Policy

Our Insider Trading Policy expressly bars hedging, derivative, or any other speculative transactions involving the Company’s stock by all directors, officers, employees and consultants of the Company, including its subsidiaries. Such prohibited transactions include hedging or derivative transactions, such as “cashless” collars, forward contracts, equity swaps or other similar or related transactions, or any short sale, “sale against the box,” or any equivalent transaction involving the Company’s stock. In addition, we prohibit our executive officers, directors, and employees from purchasing or selling our securities while in possession of material, non-public information, or otherwise using such information for their personal benefit and we maintain a quarterly black-out window where applicable individuals may not trade. We may, in appropriate circumstances, permit transactions pursuant to a blind trust or a pre-arranged trading program that complies with Rule 10b5-1 to take place during periods in which the individual entering into the transaction may have material nonpublic information or during black-out periods.

Policy Regarding Options and Similar Equity Awards

We do not currently grant new awards of stock options, stock appreciation rights or similar option-like equity awards. Accordingly, we have no specific policy or practice on the timing of grants of such awards in relation to the disclosure of material nonpublic information. In the event we determine to grant new awards of stock options or similar equity awards in the future, the Compensation Committee will evaluate the appropriate steps to take in relation to the foregoing.

Health and Welfare Benefits

All NEOs are provided with the same medical, dental, vision and life insurance programs as all other benefits-eligible employees of the Company on the same terms and conditions as applicable to these employees generally.

401(k) Savings Plan

All employees, including our NEOs, are eligible to make pre-tax contributions under the Mechanics Bank Profit Sharing/ 401(k) Plan (the “401(k) Plan”) and may be eligible to receive a discretionary matching contribution. An employer matching contribution may begin immediately after enrollment in the 401(k) Plan for employees who meet applicable service requirements. The Company may make profit sharing contributions or nonelective contributions to this plan at the discretion of the Board of Directors of the Company. Currently, the Company matches 100% on the first 1% of the employee’s eligible compensation and 50% on the next 5% of deferrals (up to a maximum of 3.5%). This matching contribution is taxable when the employee withdraws the money unless the employee elects matching funds to be contributed on a post-tax basis.

After the closing of the Merger, the legacy HomeStreet 401(k) plan was maintained separately from the Mechanics Bank 401(k) Plan. The plan was frozen as of December 31, 2025, and will merge into the Mechanics Bank 401(k) Plan in the first half of 2026.

Perquisites and Other Personal Benefits

Other than car allowances, the Company’s current executives generally receive only medical benefits, life insurance and long-term disability coverage, as well as matching contributions to the Company’s 401(k) program, on the same terms and conditions as generally available to all employees.

Prior to the Merger, the Company did not have a formal perquisite policy or provide any supplemental executive retirement plans, although the Compensation Committee periodically reviewed perquisites for our NEOs. We provide our NEOs with benefits that we believe are reasonable and consistent with our overall compensation program and beneficial to the Company in attracting and retaining qualified executives. Among these benefits are health club memberships and parking.

Employment Agreements and Change in Control Agreements

The Company does not currently maintain any employment agreements with our NEOs. We do, however, maintain change in control agreements with active NEOs other than Mr. Johnson.

On August 28, 2025, each of Messrs. Duda and Givans entered into an amended and restated change in control agreement with Mechanics Bank (the “Change in Control Agreements”). These agreements provide that in the event of a qualifying termination (described below), Mechanics Bank will pay such executive, subject to the execution by such executive of a general release, (i) a cash amount equal to 2.75 times the sum of (x) the executive’s annual base salary as in effect as of the date of the executive’s qualifying termination or, if greater, as in effect as of the date of the “Change in Control” (as defined in the Change in Control Agreements) and (y) the executive’s target annual bonus for the year in which the executive’s qualifying termination occurs or, if greater, for the year in which a Change in Control occurs and (ii) premiums for COBRA continuation coverage for a period of 18 months following such qualifying termination. The initial term will expire on the second anniversary of the date of the agreement, but the term automatically renews for successive one-year periods, unless either party provides advance written notice to the other party no less than 120 days prior to any anniversary of the date of the agreement that the term will not be further renewed, in which case the term will expire on the last day of the then-current term. The term automatically expires upon termination of the executive’s employment. Under the Change in Control Agreements, a qualifying termination means (i) the termination of the executive’s employment during the two-year period immediately following a “Change in Control” either by Mechanics Bank without “Cause” or by the executive for “Good Reason” (each as defined in the Change in Control Agreements) or (ii) the termination of the executive’s employment by Mechanics Bank during the six-month period immediately preceding a “Change in Control” (other than for Cause). The Change in Control Agreements also provide that in the event that payments to the executive become subject to the tax imposed by Section 4999 of the Code (the “Excise Tax”), then the amounts payable to the executive will be reduced (such reduction, the “Cutback”) such that such payments, in the aggregate, equal the Safe Harbor Amount (as defined in the Change in Control Agreement) if the executive would have a greater Net After-Tax Receipt (as defined in the Change in Control Agreement) of aggregate payments if such payments were so reduced. If the executive would not have a greater Net After-Tax Receipt of aggregate payments if such payments were so reduced, the executive would receive all payments to which the executive is entitled.

Each of the former executives previously had employment agreements and change in control agreements with the Company, which were in effect until their resignation in connection with the completion of the Merger. Mr. Mason, the Company and Mechanics Bank entered into a consulting agreement, dated March 28, 2025 (the “Consulting Agreement”). Pursuant to the Consulting Agreement, Mr. Mason upon termination in connection with the completion of the Merger received cash severance payments equal to the sum of (x) 2.5 times Mr. Mason’s annual salary at the rate in effect as of immediately prior to the consummation of the Merger, plus (y) 2.5 times the greater of (A) the annual incentive payment earned by Mr. Mason in the year prior to termination and (B) Mr. Mason’s target annual incentive payment for the year of termination, (ii) continuing health insurance coverage for Mr. Mason and his dependents for 18 months, provided Mr. Mason and his dependents timely elect COBRA continuation coverage under the Company’s group health plan(s), (iii) accelerated vesting of all of Mr. Mason’s unvested equity awards and cash long-term incentive awards (in the case of performance stock units, with performance deemed achieved at target) and (iv) certain accrued but unpaid benefits. Following his termination, Mr. Mason will make himself available to perform certain transitional services, on the terms and conditions set forth in the Consulting Agreement, for the period (the “Consulting Period”) beginning on September 3, 2025 and ending on the second anniversary of the effective time of the Merger, provided that the Consulting Period will terminate immediately upon the death or disability of Mr. Mason or upon an earlier termination of the Consulting Period by the Company or Mr. Mason. The Consulting Agreement provides that, during the Consulting Period, Mr. Mason will provide consulting and advisory services as may be requested from time to time by the Company, provided that in no event will Mr. Mason be required to provide services in excess of 32 hours per month. In consideration of such services and the

restrictive covenants described below, the Company will pay Mr. Mason $4,000,000 (collectively, the “Consulting Fee”). Pursuant to the terms of the Consulting Agreement, in the event of a termination of the Consulting Period prior to the second anniversary of the effective time of the Merger, the Company will have no further obligation to make further payments of the Consulting Fee, provided that if such termination is by the Company other than for “cause” (as defined in the Consulting Agreement) or by Mr. Mason due to any of Mechanics Bancorp’s or its subsidiaries’ or affiliates’ material breach of the Consulting Agreement (which breach remains uncured for 15 days after the Company or any of its subsidiaries or affiliates is provided notice of such breach), or occurs as a result of Mr. Mason’s death or disability, Mr. Mason will continue to receive such payments through the remainder of the scheduled Consulting Period, subject to Mr. Mason’s execution and non-revocation of a release of claims and continued compliance with certain restrictive covenants.

Prior to the Merger, the Company utilized employment agreements with Messrs. Mason, Michel and Endresen, each of which, as was described above, were terminated in connection with the completion of the Merger.

•Mr. Mason’s employment agreement (the “HomeStreet CEO Employment Agreement”) effective January 25, 2018 and last amended March 5, 2025, provided for an annual base salary of not less than $700,000 and eligibility for an annual performance-based incentive bonus with a target award equal to 75% of his annual salary, provided that the Board or the Compensation Committee may set a lower or higher bonus amount based on individual and Company performance and Peer Group data. Mr. Mason’s target award was 75% in 2025, and his annual base salary in 2025 was $880,750. In connection with entering into his employment agreement, Mr. Mason had entered into a change in control agreement with the Company which provided for payment and benefits in connection with a change in control.

•Mr. Michel’s initial employment agreement, effective May 11, 2020 and last amended March 5, 2025, provided for an annual base salary of not less than $435,000 and eligibility for an annual performance-based incentive bonus with a target award equal to 60% of his annual salary, provided that the Board or the Compensation Committee may set a lower or higher bonus amount based on individual and Company performance and Peer Group data. Mr. Michel’s annual base salary was $504,140 for 2025. In connection with entering into his employment agreement, Mr. Michel had entered into a change in control agreement with the Company which provided for payment and benefits in connection with a change in control.

•Mr. Endresen’s employment agreement, effective February 26, 2018 provides for an annual base salary of not less than $315,000 and a loan production commissioned based incentive plan. Mr. Endresen’s base salary was increased to $430,300 effective March 2024. On February 25, 2021, the Company entered into an amended and restated Executive Employment Agreement with Mr. Endresen, which amended and restated his prior agreement dated February 26, 2018. The material terms of his Executive Employment Agreement remain the same as they were under his prior agreement. On March 5, 2025, the term of Mr. Endresen’s employment agreement was extended. Mr. Endresen’s annual base salary in 2025 was $443,170. In connection with entering into his employment agreement, Mr. Endresen had entered into a change in control agreement with the Company which provided for payment and benefits in connection with a change in control.

Mr. Mason was also party to a deferred compensation agreement which provided for a target payout of $119,093 for the 2024 to 2026 measuring period. The actual payout amount was based on the Company’s total shareholder return relative to a peer group during the measurement period: if the relative performance is at the 25th percentile, payment is 50% of target; if at the 50th percentile, payment is 100% of target; and if at the 75th percentile, payout is 150% of target. For results in between the 25th and 50th or 50th and 75th, there was to be a straight-line interpolation calculation. If achievement was below the 25th percentile, or the Company’s absolute total shareholder return over the measurement period was negative, then 0% of the payout will have vested. The peer group consisted of all companies included in the KBW Regional Banking Index at the end of the measuring period (excluding the Company itself, if it happens to be a component company on that date). This agreement was terminated in connection with the completion of the Merger. A copy of Mr. Mason’s deferred compensation agreement is filed as Exhibit 10.19 to the fiscal year end 2025 Form 10-K.

PROPOSAL 2
ADVISORY (NON-BINDING) VOTE ON EXECUTIVE COMPENSATION

Overview

As required pursuant to Section 14A of the Exchange Act, we are asking our shareholders to indicate their support for our named executive officer compensation as described in this Proxy Statement. This proposal, commonly known as a “say-on-pay” proposal, gives our shareholders the opportunity to express their views on the compensation of our named executive officers each year. This vote is not intended to address any speciﬁc item of compensation, but rather the overall compensation of our named executive officers and our compensation policies and practices for named executive officers described in this Proxy Statement. In accordance with the requirements of the SEC, we are providing you the opportunity, as a shareholder, to endorse or not endorse our executive pay program through the following non-binding resolution:

“RESOLVED, that the compensation paid to the named executive officers for 2025, as described in the compensation tables and related materials included in the Proxy Statement, is hereby approved.”

We believe that our compensation policies and procedures are strongly aligned with the long-term interests of our shareholders. Our compensation program is designed to motivate our leaders to contribute to the achievement of our financial goals and to focus on long-term value creation for our shareholders. For more information, we invite you to consider the details of its executive compensation provided under “Executive Compensation” on page 14 of this Proxy Statement. That section provides you with information about the structure of our executive compensation and the objectives that the compensation program is intended to achieve.

We currently conduct annual advisory votes on named executive officer compensation, and we expect to conduct the next advisory vote at our 2027 annual meeting of shareholders.

Because your vote is advisory, it will not be binding upon the Board. However, we value the opinions that our shareholders express in their votes and will take into account the outcome of the vote when considering future executive compensation arrangements.

Vote Required and Board Recommendation

The proposal on the advisory (non-binding) vote to approve named executive officer compensation requires that the number of votes affirmatively cast “FOR” the matter exceeds the number of votes cast against the matter.

THE BOARD UNANIMOUSLY RECOMMENDS VOTING “FOR” APPROVAL OF THE
COMPENSATION PAID TO THE NAMED EXECUTIVE OFFICERS AS DESCRIBED IN THIS
PROXY STATEMENT.

PROPOSAL 3
ADVISORY (NON-BINDING) RATIFICATION OF APPOINTMENT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

Overview

The Audit Committee has selected Crowe as the Company’s independent registered public accounting ﬁrm to audit the consolidated ﬁnancial statements of the Company and its subsidiaries for the ﬁscal year ending December 31, 2026.

Shareholder ratiﬁcation of the appointment of Crowe is not required by our Bylaws or other applicable legal requirements. However, the Board considers it desirable for shareholders to pass upon the selection of auditors as a matter of good corporate practice. We are submitting this proposal to our shareholders on an advisory (non-binding) basis, and the outcome of the vote will not be binding on the Company. In the event that this appointment of Crowe as our independent registered public accounting ﬁrm is not ratiﬁed by our shareholders at the Annual Meeting, the appointment of Crowe as our independent registered public accounting ﬁrm will be reconsidered by the Audit Committee. Even if the selection is ratiﬁed, the Audit Committee in its discretion may direct the appointment of a different accounting ﬁrm at any time during the year if the Audit Committee determines that such a change would be in the best interests of the Company and its shareholders.

Representatives from Crowe are expected to be present at the Annual Meeting and will be given the opportunity to make a statement at the Annual Meeting if they desire to do so and respond to appropriate questions.

Fees of Independent Registered Public Accounting Firm

The following table presents fees billed for professional audit services and other services rendered to the Company by Crowe for the years ended December 31, 2025 and 2024.


($ in thousands)	2025		2024

Audit fees (1)	$	3,589	$	1,119
Audit-related fees (2)	396		120
Tax fees (3)	152		63
All other fees	—		—
Total	$	4,137	$	1,302

(1)Audit fees consist of fees billed for professional services rendered for the audit of our consolidated ﬁnancial statements included in our Annual Report on Form 10-K and for the review of our quarterly ﬁnancial statements, as well as services that generally only our independent registered public accounting ﬁrm can reasonably provide, including statutory audits and services rendered in connection with SEC ﬁlings. For 2025, this amount includes approximately $208,000 in audit fees paid by HomeStreet, Inc. prior to the closing of the Merger on September 2, 2025 in connection with Crowe’s representation of HomeStreet, Inc. prior to the Merger.

(2)Audit-related fees consist of fees for procedures related to Crowe’s consent on registration statements and other filings in connection with the Merger, 401(k) plan and other attest services.

(3)Tax fees consist of aggregate fees billed for tax consulting and tax preparation services.

Pre-Approval of Audit and Non-Audit Services

It is the responsibility of the Audit Committee to pre-approve all audit and non-audit services provided by our independent registered public accounting firm. The Audit Committee has adopted a policy authorizing certain permissible audit and non-audit services to be performed by our independent registered public accounting firm with subsequent reporting and oversight required by the Audit Committee. Permissible services, not pre-approved pursuant to this policy, require speciﬁc review and approval prior to the engagement by the Audit Committee, or a designated member. All services rendered by and fees paid to our independent registered public accounting firm are reported to and monitored quarterly by the Audit Committee. The Audit Committee considers whether the provision of related audit services is compatible with maintaining the independent registered public accounting ﬁrm’s independence. To assist the Audit Committee in its oversight responsibilities, the pre-approval policy identiﬁes the three basic principles of independence with respect to services provided by the independent registered public accounting ﬁrm: (1) whether the services are consistent with applicable rules on independent registered public accounting firm independence; (2) whether the independent registered public accounting firm is best positioned to provide the services in an effective and efficient manner, taking into consideration its familiarity with the Company’s business, people, culture, accounting systems, risk profile and other factors; and (3) whether the

service might enhance the Company’s ability to manage or control risk or improve audit quality. The pre-approval policy also identifies the non-audit services the independent registered public accounting ﬁrm is prohibited from providing. All services provided by Crowe in each of the last two ﬁscal years were pre-approved by the Audit Committee.

Engagement of Independent Registered Public Accounting Firm

In determining whether to engage or re-engage an audit ﬁrm, the Audit Committee annually considers, among other factors, the ﬁrm’s qualiﬁcations, performance and independence, including that of the lead partner, to determine whether the ﬁrm will serve in the best interest of the Company and its shareholders.

Based on the foregoing, the Audit Committee has retained Crowe as the Company’s independent registered public accounting ﬁrm for ﬁscal year 2026.

Vote Required and Board Recommendation

The proposal on the advisory (non-binding) vote to ratify the appointment of our independent registered public accounting firm requires that the number of votes affirmative cast “FOR” the matter exceeds the number of votes cast against the matter.

THE BOARD UNANIMOUSLY RECOMMENDS VOTING “FOR” THE RATIFICATION OF THE APPOINTMENT OF CROWE LLP AS THE COMPANY’S INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM FOR THE FISCAL YEAR ENDING DECEMBER 31, 2026

CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

Related Party Transactions

Ordinary Banking Transactions

The Bank, in the ordinary course of business, has deposit transactions with directors and executives. In addition, the Bank has made or acquired loans to directors and/or executives, their immediate family members, and companies in which they have an interest, in the ordinary course of its business as a bank. In management’s opinion, these loans were made on substantially the same terms, including interest rates and collateral, as those prevailing at the time for comparable loans with persons not related to the Bank and do not involve more than the normal risk of collectability or present other unfavorable features. At December 31, 2025 and 2024, respectively, there were approximately $263 thousand and $141 thousand in loans outstanding to directors, executives and their related interests. At December 31, 2025 and 2024, respectively, there were no unfunded commitments to directors, executives and their related interests. At December 31, 2025 and 2024, respectively, there were approximately $3.6 million and $3.4 million in deposit balances from directors and executives. As of the date of this filing, no related party loans were categorized as nonaccrual, past due, restructured, or potential problem loans.

Bank Services Agreement

Mechanics Bank is a party to the Mechanics Bank Services Agreement with GJF Management, an affiliate of Gerald J. Ford, a former director and now director emeritus of Mechanics Bank. GJF Management serves as the management company to Ford Financial Fund II, L.P. and Ford Financial Fund III, L.P., which collectively own approximately 77.6% of the voting power of the Company. Further, Mr. Webb, Executive Chairman of the Mechanics Bancorp and Mechanics Bank boards, is employed by GJF Management. Additionally, Mr. Johnson, President and Chief Executive Officer of Mechanics Bancorp and Mechanics Bank, is employed by GJF Management.

Either party may terminate this agreement upon thirty days’ prior notice to the other. Mechanics Bank has also agreed to indemnify and hold harmless GJF Management for its performance or provision of these services, except for gross negligence and willful misconduct.

Registration Rights Agreement

The Company, Mechanics Bank, the Ford Entities and Rabobank International Holding B.V. (“Rabobank”) entered into a registration rights agreement, dated as of March 28, 2025 (the “registration rights agreement”), which became effective on September 2, 2025 in connection with the closing of the Merger.

Pursuant to the registration rights agreement, (i) each of the Ford Entities and Rabobank is entitled to certain demand registration rights, shelf takedown rights and piggyback registration rights with respect to shares of the Company’s common stock, in each case, subject to certain minimum and maximum thresholds and other customary limitations, including the right of underwriters in an underwritten offering to limit the number of shares to be included in an offering and the Company’s right to suspend the use of (or discontinue the disposition of the Company’s common stock pursuant to) a registration statement under specified circumstances, and (ii) the Company is required to use reasonable best efforts to file, within 180 days of September 2, 2025, a resale shelf registration statement on Form S-3 covering the shares of the Company’s common stock acquired by the Ford Entities and Rabobank in the Merger.

The Company will pay the registration expenses (other than underwriting discounts, selling commissions, stock transfer taxes and fees and certain legal fees) of the shares registered pursuant to the demand registration rights, shelf takedown rights and piggyback registration rights. The applicable Ford Entities or Rabobank and its permitted transferees (the “Rabobank Parties”) will pay such underwriting discounts, selling commissions, stock transfer taxes and fees and legal fees. The Company, on the one hand, and the Rabobank Parties and the Ford Entities, on the other hand, will each indemnify the other and its representatives for certain securities law matters in connection with any registration statement.

Further, the Company, Mechanics Bank, the Ford Entities and Rabobank each agreed to, and agreed to cause their respective affiliates, to cooperate with each other with respect to certain bank regulatory matters and to use reasonable best

efforts to comply with certain regulatory requirements. As long as the Rabobank Parties beneficially own, in the aggregate, at least 4.9% of the outstanding capital stock and other classes of equity securities of the Company, the Rabobank Parties will have the right to appoint one observer to the Board of Directors, and from and after such time as the Rabobank Parties acquire additional shares of the Company’s voting common stock such that they beneficially own, in the aggregate, 9.9% or more of the Company’s voting common stock, the Rabobank Parties will have the right to appoint one director to the Board of Directors (subject to the Board’s reasonable approval).

The registration rights agreement will terminate (i) upon the mutual written agreement of each of the parties thereto, (ii) in the case of the Rabobank Parties, when the Rabobank Parties no longer beneficially own any outstanding capital stock or other class of equity securities of the Company and (iii) in the case of the Ford Entities, when the Ford Entities no longer beneficially own any outstanding capital stock or other class of equity securities of the Company.

OTHER MATTERS

Participants in the Solicitation

Under applicable regulations of the SEC, each of our directors and certain of our executive officers and other employees are “participants” in this proxy solicitation. For more information about our directors and executive officers, please see “Principal Shareholders” on page 31 of this Proxy Statement and “Proposal 1 — Election of Directors” on page 4 of this Proxy Statement. Other than the persons described in this Proxy Statement, no regular employees of the Company have been or are to be employed to solicit shareholders in connection with this proxy solicitation. However, in the course of their regular duties, employees may be asked to perform clerical or ministerial tasks in furtherance of this solicitation.

Costs of Solicitation

The Company will bear the expenses of calling and holding the Annual Meeting and the solicitation of proxies on behalf of our Board with respect to the Annual Meeting. These costs will include, among other items, the expense of preparing, assembling, printing and mailing the proxy materials to shareholders of record and beneﬁcial owners, and reimbursements paid to brokers, banks and other nominees for their reasonable out-of-pocket expenses for forwarding proxy materials to shareholders and obtaining voting instructions from beneﬁcial owners. In addition to soliciting proxies by mail, directors, officers and employees may solicit proxies on behalf of our Board, without additional compensation, personally or by telephone. We may also solicit proxies by email from shareholders who are our employees or who previously requested to receive proxy materials electronically. Excluding the salaries and wages of our regular employees, we have not incurred, and do not expect to incur, expenses related to our solicitation of proxies.

Shareholders Sharing the Same Address

SEC rules permit us to deliver only one copy of our proxy materials to multiple shareholders of record who share the same address and have the same last name, unless we have received contrary instructions from one or more of the shareholders. This delivery method, called “householding,” reduces our printing and mailing costs. Shareholders who participate in householding will continue to receive separate proxy cards.

If you are a shareholder of record who currently receives a single copy of our proxy materials and wishes to receive a separate copy of our proxy materials or if you are currently receiving multiple copies of our proxy materials at the same address and wish to receive only a single copy, please write to the Corporate Secretary at 1111 Civic Drive, Walnut Creek, California 94596 or CorporateSecretary@mechanicsbank.com.

Beneficial owners sharing an address who are currently receiving multiple copies of our proxy materials and wish to receive only a single copy in the future, or who currently receive a single copy and wish to receive separate copies in the future, should contact their bank, broker or other nominee to request that only a single copy or separate copies, as the case may be, be delivered to all shareholders at the shared address in the future.

Shareholder List

A list of our shareholders as of the close of business on April 1, 2026 will be available for inspection during business hours for 10 days prior to the Annual Meeting at our principal executive offices located at 1111 Civic Drive, Walnut Creek, California 94596. This list will also be accessible during the Annual Meeting on-site and through the meeting website www.virtualshareholdermeeting.com/MCHB2026.

Shareholders Proposals and Director Nominations for the 2027 Annual Meeting

For inclusion in the Company’s proxy materials: To be considered for inclusion in the proxy materials for next year’s annual meeting of shareholders (the “2027 Annual Meeting”) under Rule 14a-8 of the Exchange Act, proposals must be received by our Corporate Secretary no later than December 16, 2026, and must comply will all applicable requirements of Rule 14a-8 of the Exchange Act.

To be brought before an annual meeting of shareholders: In addition, our Bylaws establish an advance notice procedure for shareholders who wish to present certain matters before an annual meeting of shareholders.

In general, nominations for the election of directors may be made (1) by or at the direction of the Board or (2) by a shareholder of the Company entitled to vote at such meeting who has delivered written notice to our Corporate Secretary at our principal executive offices within the Notice Period (as deﬁned below), who was a shareholder at the time of such notice and as of the Record Date, and whose notice is in accordance with the procedures set forth in our Bylaws.

Our Bylaws also provide that the only business that may be conducted at an annual meeting is business that is speciﬁed in the notice of meeting given by or at the direction of the Board, (2) properly brought before the meeting by or at the direction of the Board or (3) properly brought before the meeting by a shareholder who has delivered written notice to our Corporate Secretary at our principal executive offices within the Notice Period (as deﬁned below), who was a shareholder at the time of such notice and as of the Record Date, and whose notice complies with our Bylaws.

Except as otherwise provided by law, our Articles of Incorporation or our Bylaws, the Executive Chairman of the meeting shall have the power and duty to determine whether a nomination or any business proposed to be brought before the meeting was made or proposed, as the case may be, in compliance with our Bylaws, and if any proposed nomination or business is not in compliance with our Bylaws, to declare that such proposal or nomination shall be disregarded.

The “Notice Period” is deﬁned as that period not earlier than 5:00 pm Pacific Time on the 120th day and not later than 5:00 pm Pacific Time on the 90th day prior to the ﬁrst anniversary of the preceding year’s annual meeting. As a result, the Notice Period for the 2027 Annual Meeting will start on January 28, 2027 and end on February 27, 2027. Our Bylaws contain different notice submission date requirements in the event our annual meeting is held more than 30 days before or 60 days after May 28, 2027.

In addition, shareholders who intend to solicit proxies in support of director nominees other than the Company’s nominees pursuant to the SEC’s universal proxy rules must comply with the additional requirements of Rule 14a-19.

ADDITIONAL INFORMATION ABOUT THE ANNUAL MEETING

1.Why am I receiving these materials?

Our Board has sent you the Notice of Internet Availability and accompanying Proxy Statement to ask for your vote, as a shareholder of the Company, on certain matters that will be voted on at the Annual Meeting. As a shareholder, you are invited to attend the Annual Meeting, virtually or in person, and are entitled to and requested to vote on the proposals set forth in this Proxy Statement.

2.Who is entitled to vote?

All shareholders of record of Mechanics Bancorp’s Class A common stock and Class B common stock, which we refer to collectively as common stock, at the close of business on April 1, 2026 are entitled to notice of, and to vote at, the Annual Meeting. Each holder of Class A common stock and Class B common stock is entitled to one (1) vote per share of common stock on matters submitted to the vote of holders of common stock. The Class A common stock and Class B common stock vote together as a single class on all matters submitted to a vote of shareholders, except as may otherwise be required by law or certain adverse amendments to the rights of Class B common stock. The common stock will vote as one class with respect to the matters described in this Proxy Statement.

3.How many shares are entitled to vote at the meeting?

As of the Record Date, an aggregate of 221,400,590 shares of our common stock, consisting of 220,286,142 shares of our Class A common stock and 1,114,448 shares of our Class B common stock, were issued, outstanding and entitled to vote at the Annual Meeting. We have no other class of stock outstanding that is entitled to vote on the matters at the Annual Meeting.

4.How many votes do I have?

Each share of common stock you own on the Record Date is entitled to one vote for each director candidate. You may NOT cumulate votes relating to the election of directors. For the other matters presented at this meeting, you are entitled to one vote for each share of common stock you owned on the Record Date.

5.Who is a registered shareholder and who is a beneﬁcial shareholder?

Registered Shareholders: A “registered shareholder” is a person or entity whose name appears in the Company’s registered list of shareholders as an owner of one or more shares of the Company’s common stock. If you are a registered shareholder, the Notice of Internet Availability, proxy card or voting instruction are being sent directly to you and you are invited to attend the Annual Meeting, whether in person or virtually through the website for the meeting using the control number provided on your Notice of Internet Availability, proxy card or voting instruction materials.

Beneﬁcial Shareholders: A “beneﬁcial shareholder” is a person or entity whose shares of the Company’s common stock are held by a bank, broker or other nominee (a.k.a. in “street name”). If you are a beneficial shareholder, the Notice of Internet Availability, proxy card or voting instruction materials are being forwarded to you by your bank, broker or other nominee who is considered the registered shareholder of those shares. As the beneficial owner, you have the right to direct your bank, broker or other nominee on how to vote your shares and you are also invited to attend the Annual Meeting in person or virtually through the website for the meeting using the control number provided on your Notice of Internet Availability, proxy card or voting instruction materials. Your bank, broker or other nominee has provided a voting instruction form for you to use in directing how to vote your shares.

Under certain circumstances, banks, brokers and other nominees are prohibited from exercising discretionary authority for beneficial owners who have not provided voting instructions to the bank, broker or other nominee, which is referred to as a “broker non-vote”. In these cases, those shares will be counted for the purpose of determining whether a quorum is present. Pursuant to applicable regulations, if you do not give instructions to your bank, broker or other nominee, we expect that your bank, broker or other nominee will not be permitted to vote your shares with respect to Proposal 1, election of directors or Proposal 2, approval on an advisory (non-binding) basis of the compensation of the Company’s named executive officers.

6.How do I vote?

Registered Shareholders: If you are a “registered shareholder,” you can vote your shares in the following four ways:

•By Internet: Visit the website shown on your Notice of Internet Availability, proxy card or voting instruction materials to vote via the Internet (www.proxyvote.com);

•By Telephone: Use the toll-free telephone number shown on your Notice of Internet Availability, proxy card or voting instruction materials to vote by telephone;

•By Mail: If you received proxy materials by mail, you can vote by submitting a proxy by mail by completing, signing and dating your proxy card and mailing it using the postage pre-paid envelope that was enclosed with your proxy materials. Note that you cannot vote by marking the Notice of Internet Availability and returning it. The Notice of Internet Availability provides instruction on how to vote via the Internet and how to request paper copies of the proxy materials.

•At the Annual Meeting: If you virtually attend the Annual Meeting through the website provided using the control number from your Notice of Internet Availability, proxy card or voting instruction materials, you may vote your shares associated with that control number online during the Annual Meeting. However, you are encouraged to read the Proxy Statement and vote by telephone or by Internet or complete, sign and date your proxy card and mail it using the postage pre-paid envelope that was enclosed with your proxy materials regardless of whether you plan to attend the Annual Meeting to ensure your vote is counted.

Beneﬁcial Shareholders: If you are a “beneﬁcial shareholder,” then you will receive voting instructions from your bank, broker or other nominee on how you may vote your shares, which will include a control number that you can use to virtually attend the Annual Meeting on the website www.virtualshareholdermeeting.com/MCHB2026. You may also attend the Annual Meeting in person.

For more information, please see “Additional Information about the Annual Meeting” — How do I attend and participate in the Annual Meeting on page 39 of this Proxy Statement.

7.What is a proxy?

A proxy is your legal designation of another person to vote the stock you own. That other person is called a proxy. If you designate someone as your proxy in a written document, that document is also called a proxy or a proxy card. We have designated C.J. Johnson and Laura Jacob, as the Company’s proxies for the Annual Meeting.

8.What should I do if I receive more than one proxy card or set of proxy materials from the Company?

Your shares may be owned through more than one brokerage or other share ownership account. In order to vote all of the shares that you own, you must either sign and return all of the proxy cards or follow the instructions for any alternative voting procedure on each of the proxy cards that you receive.

Please note that if you have more than one account through which you hold shares, you will receive more than one control number. The control number is used to vote your shares, and is also used to log on to the meeting website to virtually attend the meeting, which will allow you to vote the shares held in the account associated with that control number at the meeting. However, you will not be able to vote shares held in other accounts not associated with the control number you are using to log in to the virtual shareholder meeting. Therefore, it is important that you return your proxy cards for all of your accounts prior to the Annual Meeting so that all of your shares may be counted.

9.Can I revoke my proxy?

Yes. You can revoke your proxy and/or change your vote at any time prior to the Annual Meeting as described below. Only your latest dated voting instructions or proxy will count.

Registered Shareholders: If you are a “registered shareholder” who has properly executed and delivered a proxy, you may revoke such proxy at any time before the Annual Meeting in any of the following ways:

•submitting another proxy with a later date by telephone or by Internet or by signing, dating and returning your proxy card using the instructions on your proxy card;

•sending a written notice of revocation to our Corporate Secretary at Mechanics Bancorp, 1111 Civic Drive, Walnut Creek, California 94596; or

•voting online during the Annual Meeting at www.virtualshareholdermeeting.com/MCHB2026.

Beneﬁcial Shareholders: If you are a “beneficial shareholder,” you may change your vote by submitting new voting instructions to your bank, broker or nominee in accordance with such bank, broker or nominee’s procedures. You can use your control number to log into and virtually attend the Annual Meeting and change your vote during the meeting, or you can also attend the meeting in person and change your vote during the meeting.

10.How will my shares be voted if I return the proxy card?

The shares represented by any proxy card that is properly executed and received by the Company prior to or at the Annual Meeting will be voted in accordance with the speciﬁcations made on that proxy card. Where a choice has been speciﬁed on the proxy card with respect to the proposals, the shares represented by the proxy card will be voted in accordance with the speciﬁcations.

The Board is not aware of any matters that are expected to come before the Annual Meeting other than those described in this Proxy Statement. If any other matter should be presented at the Annual Meeting upon which a vote may be properly taken, shares represented by the proxy cards received by the Board will be voted with respect thereto at the discretion of the person or persons named as proxies in the enclosed proxy card.

11.What happens if I sign and return my proxy card, but don’t mark my votes?

If you return a validly executed proxy card without indicating how your shares should be voted on a matter and you do not revoke your proxy, your proxy will be voted: “FOR” the election of the eight director nominees of the Board set forth on the proxy card (Proposal 1); “FOR” the approval on an advisory (non-binding) basis of the compensation of the Company’s named executive officers as described in the Proxy Statement under “Executive Compensation” (Proposal 2); and “FOR” the ratiﬁcation on an advisory (non-binding) basis of the appointment of Crowe LLP as the independent registered public accounting ﬁrm of the Company for the fiscal year ending December 31, 2026 (Proposal 3).

12.Will my shares be voted if I do nothing?

If your shares are registered in your name, you must sign and return a proxy card in order for your shares to be voted, unless you vote by telephone or by Internet or vote during the Annual Meeting (whether virtually or in person). If your shares are held in “street name” (that is, held for your account by a bank, broker or other nominee) and you do not instruct your bank, broker or other nominee how to vote your shares, your bank, broker or other nominee may not have discretionary authority to vote your shares on with respect to the election of directors (Proposal 1) or the approval on an advisory (non-binding) basis of the compensation of the Company’s named executive officers (Proposal 2). If you do not instruct your bank, broker or other nominee as to how to vote your shares and your bank, broker or other nominee does not have discretionary voting authority, these unvoted shares will be “broker non-votes”. Banks, brokers or other nominees generally may only exercise discretionary voting authority to vote “routine” proposals. The ratification on an advisory (non-binding) basis of the appointment of our independent registered public accounting firm for the fiscal year ending December 31, 2026 (Proposal 3) is the only routine proposal to be presented at the Annual Meeting. We do not expect broker non-votes on Proposal 3.

YOUR VOTE IS VERY IMPORTANT. To assure that your shares are represented at the Annual Meeting, we ask you to vote by telephone or by Internet by following the instructions on the Notice of Internet Availability, proxy card or voting instruction materials or by completing, signing and dating your proxy card and promptly mailing it in the postage-paid envelope enclosed with your proxy materials, whether or not you plan to attend the Annual Meeting.

13.How do I attend and participate in the Annual Meeting virtually?

The Annual Meeting will be held both through an online virtual meeting webcast at www.virtualshareholdermeeting.com/MCHB2026, and in person at 1111 Civic Drive, Walnut Creek, California 94596.

The virtual meeting webcast on May 28, 2026 will begin promptly at 9:00 a.m. Pacific Time. We encourage you to access the meeting prior to the start time. Online check-in will begin at 8:45 a.m. Pacific Time, and you should allow ample time for the check-in procedures.

Only Mechanics Bancorp shareholders or their duly authorized and constituted proxies may attend the Annual Meeting. The control number printed on your Notice of Internet Availability, proxy card or voting instruction materials is required to virtually attend the meeting through the website at www.virtualshareholdermeeting.com/MCHB2026 regardless of whether you are a registered shareholder or a beneficial shareholder. We have been advised that Google Chrome and Microsoft Edge browsers will give the best user experience for participation in the virtual meeting.

Our Executive Chairman is expected to lead the meeting, and members of our Board are expected to be present and available during the Annual Meeting. During the Annual Meeting, you will be able to hear the business of the meeting as it is conducted, vote your shares if you have not already done so, access information that would normally be available at an in-person annual meeting, including the list of shareholders entitled to vote at the meeting, and submit questions to be answered by our Executive Chairman of the Board. Questions pertinent to meeting matters will be answered during the meeting, subject to time constraints, and additional instructions regarding the question and answer period of the Annual Meeting will be posted on the virtual meeting website.

The virtual Annual Meeting has been designed to provide the same rights to participate as you would have at an in-person meeting. Shareholders participating in the Annual Meeting virtually will be in a listen-only mode and will not be able to speak during the webcast. However, in order to maintain the interactive nature of the meeting, virtual attendees are able submit questions before and during the meeting through the virtual meeting portal. To submit a question, log into the virtual meeting platform at www.virtualshareholdermeeting.com/MCHB2026, type your question into the “Ask a Question” field, and click “Submit.” Questions and answers may be grouped by topic and substantially similar questions may be grouped and answered once. In order to promote fairness and efficient use of time, we will respond to up to two questions from a single shareholder and may not be able to respond to all questions.

Our virtual Annual Meeting website will be hosted by Broadridge Financial Solutions, Inc. In the event you have any technical difficulties logging into the meeting, please call the technical support number that will be posted on the virtual meeting platform at www.virtualshareholdermeeting.com/MCHB2026.

14.How do I attend the Annual Meeting in person?

An admission card or other proof of ownership, together with valid government-issued photo identification such as a driver’s license or passport, are required to attend the Annual Meeting. The registration desk will open at 8:45 a.m. Pacific Time on the day of the meeting, and the meeting will begin at 9:00 a.m. Pacific Time.

If you own shares in street name, you will need to ask your bank or broker for an admission card in the form of a confirmation of beneficial ownership. You will need to bring a confirmation of beneficial ownership with you to vote at the Annual Meeting. If you do not receive your confirmation of beneficial ownership in time, bring your most recent brokerage statement with you to the Annual Meeting. We can use that to verify your share ownership and admit you to the meeting; however, you will not be able to vote your shares at the Annual Meeting without a confirmation of beneficial ownership.

If you intend to attend the Annual Meeting in person, please preregister with the Company’s Investor Relations department no later than 5:00 p.m. Pacific Time on May 21, 2026.

For safety reasons, we will not allow anyone to bring large bags, briefcases, packages, or other similar items into the meeting or secondary rooms, or to record or photograph the meeting.

15.What constitutes a “quorum”?

A majority of the outstanding shares of common stock entitled to vote at the Annual Meeting, present in person (including virtually) at the Annual Meeting or represented by proxy, will constitute a quorum for the transaction of business at the Annual Meeting. Votes withheld, abstentions and broker non-votes will be counted as present or represented for purposes of determining the presence or absence of a quorum for the Annual Meeting. Without a quorum, no business may be transacted at the Annual Meeting. If less than a quorum of the outstanding shares is represented at the Annual Meeting, a majority of the shares so represented may adjourn the Annual Meeting without further notice.

16.What vote is required to approve each of the matters to be voted on at the Annual Meeting?

Proposal

Vote Required

Broker

Discretionary

Voting

Proposal 1: Election of eight directors

Majority of votes cast *

Proposal 2: Approval on an advisory (non-binding) basis of the compensation of the Company’s named executive officers

Number of votes cast in favor exceeds number of votes cast against

Proposal 3: Ratification on an advisory (non-binding) basis of the appointment of our independent registered public accounting firm for 2026

Number of votes cast in favor exceeds number of votes cast against

Yes

* Under the Bylaws, the voting standard in an uncontested election is a majority of votes cast standard. See “What vote is required to elect directors?” below.

17.What is the effect of abstentions and broker non-votes?

If you specify that you wish to “abstain” from voting on an item (or “abstain” from voting for a director), then your shares will not be voted on that particular item. Abstentions and broker non-votes are not considered “votes cast” and so are not counted either “for” or “against” any proposal that requires a majority of votes cast in order to pass, which includes all of the proposals being presented at the Annual Meeting (including the non-contested election of directors).

18.What vote is required to elect directors?

Our Bylaws provide that, in any election of directors that is not a “contested election” (as defined in our Bylaws and described below), the candidates elected are those receiving a majority of the votes cast. Therefore, to be elected, the number of votes cast “FOR” a nominee must exceed the number of votes cast “AGAINST” that nominee.

The term of any director nominee who is a director at the time of election and who does not receive a majority of votes cast in the election held under the majority voting standard described above terminates on the earliest to occur of: (i) 90 days after the date on which the voting results of the election are determined; (ii) the date the director’s resignation is accepted by the Board; or (iii) the date the Board fills the position. The following will not be votes cast and will have no effect on the election of any director nominee: (i) a share whose ballot is marked as “withheld”; (ii) a share otherwise present at the meeting but for which there is an abstention; and (iii) a share otherwise present at the meeting as to which a shareholder gives no authority or direction (other than a share voted pursuant to a signed proxy card on which the shareholder has not indicated any voting direction). Broker non-votes will have no effect on the outcome of this proposal. Shareholders may not cumulate their votes in the election of directors.

Our Bylaws provide that an election is considered “contested,” and will be held under a plurality standard, if (a) the Secretary of the Company receives a notice that a shareholder has nominated a person for election to the Board in compliance with the advance notice requirements for shareholder nominees set forth in Section 1.13 of our Bylaws who are not withdrawn by the advance notice deadline set forth in that section and (b) the Board has not determined before the notice of meeting is given that the shareholder’s nominee(s) do not create a bona fide election contest. No such shareholder notice was received by the Company in advance of this Annual Meeting.

19.What vote is required to approve, on an advisory (non-binding) basis, the compensation of the Company’s named executive officers and the ratiﬁcation of the appointment of our independent registered public accountants for the fiscal year ending December 31, 2026?

Each of the proposals to approve, on an advisory (non-binding) basis, the compensation of the Company’s named executive officers and the appointment of Crowe as the Company’s independent registered public accounting ﬁrm for the fiscal year ending December 31, 2026 will be adopted if a majority of the votes present in person or by proxy and voting on such matter are cast “for” the proposal. You may vote “for,” “against” or “abstain” from approving the proposal. Abstentions and broker non-votes will have no effect on the outcome of the proposal.

20.Who will count the votes?

Broadridge Financial Solutions, Inc. will serve as the independent inspector of election and, in such capacity, will count and tabulate the votes.

21.Where can I ﬁnd the results of the Annual Meeting?

We intend to announce preliminary voting results at the Annual Meeting and intend to publish ﬁnal results in a Current Report on Form 8-K, which we will ﬁle with the SEC within four business days after the Annual Meeting.

22.Who can help answer any other questions I may have?
