C.J. Johnson, President and CEO of Mechanics, said, “We had a productive first quarter of 2026 and I’m happy to report we successfully converted all Legacy HomeStreet customers onto Mechanics Bank’s core banking platform during the final week of March. This was a major milestone that was achieved thanks to a tremendous amount of planning and hard work from all our employees. We will substantially complete our merger integration during the second quarter and as a result expect to realize significant additional expense synergies moving forward.”

Nathan Duda, CFO of Mechanics, added, “Our reported net income of $44.1 million for the first quarter was impacted by several notable items that do not reflect the underlying performance of the franchise. These included $6.5 million of pre‑tax provision expense related to qualitative factor adjustments arising from geopolitical uncertainty, $4.8 million of merger‑related expenses, and a $1.7 million remeasurement of deferred tax assets.”

Presentation of Results – HomeStreet Bank Merger

On September 2, 2025, the merger of HomeStreet Bank, the wholly owned subsidiary of Mechanics Bancorp (formerly known as HomeStreet, Inc.) with and into Mechanics Bank, was completed. Mechanics Bank is the accounting acquirer (legal acquiree), HomeStreet Bank is the accounting acquiree and Mechanics Bancorp is the legal acquirer. Mechanics’ financial results for all periods ended prior to September 2, 2025 reflect Mechanics Bank’s historical financial results on a standalone basis and results of the combined company beginning September 2, 2025. In addition, for periods prior to September 2, 2025, the number of shares issued and outstanding, earnings per share, and all references to share quantities or metrics of Mechanics have been retrospectively restated to reflect the equivalent number of shares issued in the merger since the merger was accounted for as a reverse acquisition. As the accounting acquirer, Mechanics Bank remeasured the identifiable assets acquired and liabilities assumed in the merger as of September 2, 2025 at their acquisition date fair values. The estimates of fair value were recorded based on valuations as of the merger date. These estimates are considered preliminary as of March 31, 2026, are subject to change for up to one year after the merger date, and any changes could be material.

Adoption of Purchased Seasoned Loans Accounting Standard

The Company early adopted Accounting Standards Update (“ASU”) 2025-08, “Financial Instruments–Credit Losses (Topic 326): Purchased Loans,” during the fourth quarter of 2025. This new standard, which the Company elected to early adopt as of January 1, 2025, requires acquired loans that meet certain criteria at acquisition (purchased seasoned loans) to be recognized at their purchase price plus the amount of the allowance for expected credit losses (gross-up approach). As a result, for purchased seasoned loans acquired in the HomeStreet merger, the Company established an allowance for credit losses of $20.3 million at the date of acquisition for these loans and reversed the provision for credit losses recorded in the third quarter of 2025, and recorded it as part of the acquired loans initial amortized cost basis. Required disclosures regarding the impact of the adoption were presented when the Company filed its annual report on Form 10-K for the year ended December 31, 2025. In addition, third quarter 2025 results will be retrospectively adjusted when the Company files its quarterly report on Form 10-Q for the quarter ended September 30, 2026.

The impact of the adoption is reflected in the respective comparative prior period results presented in this earnings release for the fourth quarter of 2025 and as of September 30, 2025.

(1)Prior period comparative disclosures for the fourth quarter of 2025 have been adjusted to reflect the impact of adoption of ASU 2025-08.

Net Interest Income

Net interest income in the first quarter of 2026 was $3.9 million lower than the fourth quarter of 2025 primarily as a result of a decrease in average interest earning assets of $622.1 million, partially offset by lower interest expense on certificates of deposit. Mechanics’ net interest margin increased from 3.50% (2) to 3.61% primarily due to lower cost of deposits from Fed rate cuts and runoff of higher cost certificates of deposit.

(2)Net interest margin for the fourth quarter of 2025 has been adjusted to reflect the impact of adoption of ASU 2025-08.

Provision for Credit Losses

The provision for credit losses in the first quarter of 2026, which consists of the provision for credit losses on loans and provision for unfunded commitments, was $7.8 million, compared to a reversal of provision of $3.2 million for the fourth quarter of 2025. Although net charge-offs were favorable and credit metrics remained strong, the provision in the first quarter of 2026 was driven primarily by an increase in provision of $6.5 million related to economic uncertainty and the potential impact of higher energy prices stemming from the conflict in the Middle East. The reversal of provision in the fourth quarter of 2025 was primarily due to lower loan balances due to repayments during the quarter.

Noninterest Income

Noninterest income in the first quarter of 2026 decreased from the fourth quarter of 2025 primarily due to the preliminary bargain purchase gain from the HomeStreet merger of $55.1 million in the fourth quarter of 2025.

3

Noninterest Expense

Noninterest expense increased $917 thousand in the first quarter of 2026 compared to the fourth quarter of 2025, primarily due to a slight increase in non-recurring acquisition and integration related costs recognized with the HomeStreet merger, which were $4.8 million in the first quarter of 2026 compared to $3.5 million in the fourth quarter of 2025.

Income Taxes

Our effective tax rate during the first quarter of 2026 was 28.7% as compared to 17.8% in the fourth quarter of 2025 and our federal statutory rate was 21.0%. The effective tax rate increased compared to the prior quarter as a result of a $1.7 million remeasurement of deferred tax assets. In addition, the bargain purchase gain was the primary reason for the low effective tax rate in the fourth quarter of 2025.

Investment Securities

Trading securities totaled $49.5 million at March 31, 2026 and December 31, 2025. Securities available-for-sale decreased by $59.7 million during the first quarter of 2026 to $3.9 billion at March 31, 2026, primarily due to paydowns and declines in fair values. Securities held-to-maturity decreased by $23.1 million in the first quarter of 2026, due to paydowns, and totaled $1.3 billion at March 31, 2026.

Loans

Total loans at March 31, 2026 were $13.9 billion, a decrease of $324.7 million from $14.2 billion at December 31, 2025, due primarily to loan repayments during the quarter.

4

Deposits

Total deposits decreased by $782.2 million during the first quarter of 2026 to $18.2 billion at March 31, 2026. The net decrease was due primarily to maturities of certificates of deposit acquired in the HomeStreet merger, as well as seasonal outflows in noninterest-bearing demand deposits.

Noninterest-bearing demand deposits totaled $6.5 billion and represented 36% of total deposits at March 31, 2026, compared to $6.7 billion, or 35% of total deposits, at December 31, 2025.

Borrowings

Total borrowings were $128.8 million at March 31, 2026, compared to $192.0 million at December 31, 2025. The decrease in the first quarter of 2026 was due to the redemption of our $65.0 million of Senior Notes on March 1, 2026.

Equity

During the first quarter of 2026, total shareholders’ equity decreased by $71.0 million to $2.8 billion and tangible common equity (1) decreased by $63.8 million to $1.7 billion at March 31, 2026. The decrease in total shareholders’ equity for the first quarter of 2026 primarily resulted from a net decrease in retained earnings in the first quarter of 2026 from net income, less dividends paid to common shareholders, and a decrease in accumulated other comprehensive income due to changes in fair value of securities available-for-sale.

At March 31, 2026, book value per common share decreased to $12.61, compared to $12.93 at December 31, 2025. At March 31, 2026, tangible book value per common share (1) decreased to $7.53, compared to $7.81 at December 31, 2025.

At March 31, 2026, total delinquent loans were $77.0 million, compared to $93.1 million at December 31, 2025. The decrease was primarily due to improvement in auto loan portfolio delinquencies. Total delinquent loans as a percentage of total loans were 0.56% at March 31, 2026, as compared to 0.66% at December 31, 2025.

At March 31, 2026, nonperforming assets were $53.1 million, compared to $51.8 million at December 31, 2025. The slight increase was primarily due to a commercial real estate loan that was modified and was placed on nonaccrual status. Nonperforming assets as a percentage of total assets increased to 0.25% at March 31, 2026, as compared to 0.23% at December 31, 2025.

(1) Prior period comparative disclosures for the fourth quarter of 2025 have been adjusted to reflect the impact of adoption of ASU 2025-08. As discussed in “Adoption of Purchased Seasoned Loans Accounting Standard,” for purchased seasoned loans acquired in the HomeStreet merger, the Company established an allowance for credit losses of $20.3 million at the date of acquisition for these loans and reversed the provision for credit losses recorded in the third quarter of 2025, and recorded it as part of the acquired loans initial amortized cost basis.

(2) Ratios are annualized.

The allowance for credit losses on loans totaled $156.8 million, or 1.13% of total loans at March 31, 2026, compared to $153.3 million, or 1.08% of total loans at December 31, 2025. The increase in allowance was the result of an increase in qualitative factors across loan types, with the greatest impact on commercial real estate loans due to the size of the portfolio. The qualitative factor increase was primarily driven by economic uncertainty and the potential impact of higher energy prices stemming from the conflict in the Middle East.

The following factors, among others, could cause actual results to differ materially from those set forth in the forward-looking statements: substantial non-recurring and integration costs, which may be greater than anticipated due to unexpected events;

the soundness of other financial institutions; our ability to maintain sufficient liquidity, or an increase in the cost of liquidity; unpredictable economic, market and business conditions; interest rate risk, and fluctuations in interest rates; inflationary pressures and rising prices; adverse changes in real estate market values; the impact of climate change, including indirectly through impacts on our customers; the adequacy of our allowances for credit losses for loans and debt securities; incurring losses in our loan portfolio despite strict adherence to our underwriting practices; fluctuations in our mortgage origination business based upon seasonal and other factors; our geographic concentration, which may magnify the adverse effects and consequences of any regional or local economic downturn; the accuracy of independent appraisals to determine the value of the real estate that secures a substantial portion of our loans; the ability of our small- to medium-sized borrowers to weather adverse business developments;

the potential that we may identify material weaknesses in our internal control over financial reporting in the future, which may result in material misstatements of our financial statements; the potential that we may write off goodwill and other intangible assets resulting from business combinations; dependence on our management team; exposure to fraudulent and negligent acts by our customers and the parties they do business with, as well as from employees, contractors and vendors; legal claims and litigation, including potential securities law liabilities; employee class action lawsuits or other legal proceedings; our ability to raise additional capital, if needed; competition from other financial institutions and financial service companies; regulatory restrictions that may delay, impede or prohibit our ability to consider certain acquisitions and opportunities; extensive supervision and regulation that could restrict our activities and impose financial requirements or limitations on the conduct of our business and limit our ability to generate income; our ability to comply with stringent capital requirements; the impact of federal and state regulators’ examination of our business; our ability to comply with the Bank Secrecy Act and other anti-money laundering statutes and regulations; our reliance on dividends from Mechanics Bank; our ability to raise debt or capital to pay off our debts upon maturity; our level of indebtedness following the completion of the HomeStreet merger; increasing and continually evolving cybersecurity and other technological risks; our ability to adapt to rapid technological change; our ability to effectively implement new technological solutions or enhancements to existing systems or platforms; our ability to manage risks and challenges relating to the development and use of artificial intelligence; our dependence on our computer and communications systems; our ability to effectively manage and aggregate data; Ford Financial Funds and their controlled affiliates control approximately 77% of the voting power of Mechanics, and have the ability to elect all of our directors and control most other matters submitted to our shareholders for approval; we are a “controlled company” within the meaning of the rules of Nasdaq, and, as a result, we qualify for, and rely on, exemptions from certain corporate governance standards; future sales of shares by existing shareholders could cause our stock price to decline; our reliance on certain entities affiliated with the Ford Financial Funds for services; reduced disclosure requirements as a smaller reporting company; and certain of our shareholders have registration rights, the exercise of which could adversely affect the trading price of our common stock.

Presentation of Results – HomeStreet Bank Merger On September 2, 2025, the merger of HomeStreet Bank, the wholly owned subsidiary of Mechanics Bancorp (formerly known as HomeStreet, Inc.) with and into Mechanics Bank, was completed. Mechanics Bank is the accounting acquirer (legal acquiree), HomeStreet Bank is the accounting acquiree and Mechanics Bancorp is the legal acquirer. Mechanics’ financial results for all periods ended prior to September 2, 2025 reflect Mechanics Bank’s historical financial results on a standalone basis. In addition, Mechanics’ reported financial results reflect Mechanics Bank’s financial results on a standalone basis until the closing of the merger on September 2, 2025 and results of the combined company beginning September 2, 2025. For periods prior to September 2, 2025, the number of shares issued and outstanding, earnings per share, and all references to share quantities or metrics of Mechanics have been retrospectively restated to reflect the equivalent number of shares issued in the merger since the merger was accounted for as a reverse acquisition. As the accounting acquirer, Mechanics Bank remeasured the identifiable assets acquired and liabilities assumed in the merger as of September 2, 2025 at their acquisition date fair values. Adoption of Purchased Seasoned Loans Accounting Standard The Company early adopted Accounting Standards Update (“ASU”) 2025-08, “Financial Instruments–Credit Losses (Topic 326): Purchased Loans,” during the fourth quarter of 2025. This new standard, which the Company elected to early adopt as of January 1, 2025, requires acquired loans that meet certain criteria at acquisition (purchased seasoned loans) to be recognized at their purchase price plus the amount of the allowance for expected credit losses (gross-up approach). As a result, for purchased seasoned loans acquired in the HomeStreet merger, the Company established an allowance for credit losses of $20.3 million at the date of acquisition for these loans and reversed the provision for credit losses recorded in the third quarter of 2025, and recorded it as part of the acquired loans initial amortized cost basis. Required disclosures regarding the impact of the adoption were presented when the Company filed its Annual Report on Form 10-K for the year ended December 31, 2025. In addition, third quarter 2025 results will be retrospectively adjusted when the Company files its Quarterly Report on Form 10-Q for the quarter ended September 30, 2026. The impact of the adoption is reflected in the respective comparative prior period results presented in this presentation for the third and fourth quarter of 2025. General Note The sum of the amounts in tables and charts may not equal the total amounts presented due to rounding. 3

We are working to grow each of our core business lines across our West Coast footprint with a technology roadmap that is increasingly focused on leveraging AI tools to improve productivity ➢ We expect a relatively flat NIM for the next 2-3 quarters as auto loan runoff remains a drag. Our deposit costs will also flatten out as we no longer assume any Fed rate cuts. Our NIM should begin expanding again in early 2027 as the impact of auto fades, driven by Legacy Mechanics Bank earning asset repricing ➢ We project a ~17-18% ROATCE and ~1.3-1.4% ROAA in 2027 and beyond; $275 – $300mm of 2027E GAAP net income ➢ Lower earnings primarily due to (i) no rate cuts assumed vs. two cuts previously; (ii) ~$400mm lower high-cost CD balances; and (iii) ~$200mm lower construction balances
