Mechanics Bancorp lifts profit on HomeStreet merger

Earnings surge on merger-related gains

Mechanics Bancorp reported sharply higher profit for the fourth quarter and full year 2025, driven largely by its acquisition of HomeStreet Bank and associated accounting impacts. For Q4 2025, net income rose to $124.3 million, or $0.54 per diluted Class A share, compared with $55.2 million, or $0.25 per share, in Q3 2025 and $51.7 million a year earlier. For the full year 2025, net income increased to $265.7 million, or $1.22 per diluted share, versus $29.0 million, or $0.14 per share, in 2024.

The September 2, 2025 merger of HomeStreet Bank into Mechanics Bank transformed the company’s scale and earnings profile. Mechanics Bank is the accounting acquirer, so pre‑merger periods reflect only Mechanics’ historical results, while 2025 includes four months of combined operations. A preliminary bargain purchase gain from the transaction totaled $145.5 million for the year, including $90.4 million recognized in Q3 and $55.1 million in Q4, materially lifting reported profitability.

President and CEO C.J. Johnson described the quarter as “very strong” and highlighted progress on merger integration, while acknowledging that additional work remains. Chief Financial Officer Nathan Duda said the updated valuation of the bank’s Fannie Mae DUS intangible increased the total bargain purchase gain beyond original expectations.

Net interest income and margins improve

Quarterly net interest income rose to $181.5 million in Q4 2025 from $145.7 million in Q3 and $128.4 million in Q4 2024, reflecting the inclusion of HomeStreet’s loan portfolio and higher yields on securities. For full year 2025, net interest income increased by $66.5 million to $585.7 million, as the net interest margin expanded to 3.43% from 3.31% in 2024.

In Q4, the net interest margin improved to 3.47% from 3.36% in Q3, supported by a full quarter of interest income on acquired loans and a slightly lower cost of deposits. Management attributed the annual margin increase to a seven basis point rise in earning‑asset yields and a 15 basis point reduction in rates paid on interest‑bearing liabilities, aided by the payoff of $750 million of Bank Term Funding Program borrowings in September 2024.

Total interest income in Q4 2025 was $255.1 million, up from $204.9 million in Q3, while interest expense rose to $73.7 million from $59.2 million, reflecting a larger deposit base and higher long‑term debt balances acquired in the merger. The total cost of deposits was 1.43% for Q4 and 1.40% for the full year.

Credit provisioning, asset quality and new loan accounting

Mechanics recorded a net reversal of provision for credit losses of $23.5 million in Q4 2025, compared with a $47.0 million provision in Q3 and a $4.7 million reversal in Q4 2024. For the full year, the provision for credit losses on loans and unfunded commitments was $19.5 million, versus a $1.5 million net reversal in 2024.

The Q4 reversal primarily reflected the company’s early adoption of Accounting Standards Update 2025‑08 for purchased seasoned loans. Mechanics established a $20.3 million allowance for credit losses at acquisition for certain HomeStreet loans and reversed provision previously recorded in Q3, eliminating a double count of credit marks and allowances on those portfolios. Loan repayments, particularly in the higher‑reserved auto portfolio, further reduced required reserves.

Asset quality metrics remained stable to improving. Nonperforming assets declined to $51.8 million at December 31, 2025 from $64.9 million at September 30, with nonperforming assets representing 0.23% of total assets. Total delinquent loans were $93.1 million, or 0.66% of loans held for investment, little changed from 0.65% in the prior quarter. The allowance for credit losses on loans was $153.3 million, equal to 1.08% of loans, down from 1.16% at September 30.

Expenses, integration costs and efficiency

Noninterest expense fell to $129.5 million in Q4 2025 from $163.3 million in Q3, mainly due to a sharp decline in acquisition and integration charges. Such costs were $3.5 million in Q4 versus $63.9 million in Q3, and totaled $73.4 million for full‑year 2025. Other operating expenses increased with the inclusion of four months of legacy HomeStreet operations.

Excluding intangible amortization, the non‑GAAP efficiency ratio improved to 46.9% in Q4 from 62.3% in Q3 and 55.6% in Q4 2024. For the year, the adjusted efficiency ratio was 55.9%, better than 87.5% in 2024, reflecting higher revenue, the bargain purchase gain and cost actions. Johnson said the bank is progressing in eliminating redundant costs and remains on track to achieve expected merger‑related savings by Q4 2026.

Total noninterest income was $78.5 million in Q4, down from $109.8 million in Q3, as the bargain purchase gain recognized in the quarter was smaller. Excluding that item, fee‑based revenues such as service charges, trust fees and ATM income continued to provide diversification but remain smaller contributors than net interest income.

Balance sheet trends, capital and liquidity

At December 31, 2025, Mechanics reported total assets of $22.4 billion, slightly below $22.7 billion at September 30 but up from $16.5 billion a year earlier, reflecting the addition of HomeStreet. Total loans held for investment were $14.2 billion, down $392 million during Q4 due mainly to repayments. Securities available‑for‑sale increased by $502.9 million in the quarter to $4.0 billion, while held‑to‑maturity securities declined modestly to $1.34 billion.

Total deposits decreased by $428 million in Q4 to $19.0 billion, largely because of maturing certificates of deposit acquired in the HomeStreet merger. Noninterest‑bearing deposits were stable at $6.7 billion, representing 35% of total deposits. Insured deposits were $12.2 billion, or 64% of the total, compared with 66% at September 30. The company reported no wholesale funding, with all HomeStreet Federal Home Loan Bank borrowings and brokered deposits paid off.

Capital ratios remained strong. At December 31, 2025, Mechanics Bancorp’s total risk‑based capital ratio was 16.28% and Tier 1 leverage ratio was 8.65%, both preliminary. Shareholders’ equity increased by $88.2 million during Q4 to $2.86 billion. Book value per common share rose to $12.93 from $12.54 at September 30, while tangible book value per common share ticked up to $7.81.

Outlook and investor communications

Management emphasized that 2025 results were materially influenced by the HomeStreet merger and related accounting changes, and that 2026 will be an important year for completing integration and realizing cost synergies. The company highlighted available borrowing capacity of $6.2 billion from the FHLB, $4.4 billion from the Federal Reserve and $5.3 billion under lines with other institutions, underscoring ample liquidity.

Mechanics plans to provide additional detail on the merger accounting and the implementation of the purchased seasoned loans standard in its 2025 Form 10‑K and to retrospectively adjust Q3 2025 results in its Q3 2026 Form 10‑Q. The bank also scheduled a conference call and webcast for January 30, 2026 to discuss Q4 and full‑year performance with investors and analysts, noting that certain 2025 capital ratios and fair value estimates remain preliminary and subject to change within the permitted one‑year measurement period following the merger.
