American River Conversion Complete

Bank of Marin Bancorp, "Bancorp" (NASDAQ:BMRC), parent company of Bank of Marin, "Bank," announced earnings of $10.5 million in the first quarter of 2022, compared to $9.7 million in the fourth quarter of 2021 and $8.9 million in the first quarter of 2021. Diluted earnings per share were $0.66 in the first quarter, $0.61 in the prior quarter, and $0.66 in the same quarter last year. First quarter 2022 and fourth quarter 2021 earnings were impacted by the costs associated with our recent acquisition, the details of which are discussed throughout this report.

"During the first quarter, we successfully completed the system conversion of American River Bankshares, our largest conversion to date, with minimal disruption to customers," said Tim Myers, President and Chief Executive Officer. "As loan demand increases in the market, our talented teams are well positioned to capitalize on this trend and drive new loan originations across our newly expanded footprint."

Bancorp also provided the following highlights from the first quarter of 2022:

Conversion of our core systems occurred in March, bringing acquired American River Bank ("ARB") accounts and key systems under the umbrella of Bank of Marin. For a smooth end-user experience in line with standards of legendary service, extra resources were deployed to assist our customers with the transition.

Merger-related one-time and conversion costs reduced net income by $385 thousand, net of taxes, or $0.02 per share in the quarter. As shown in the reconciliation of GAAP to non-GAAP financial measures on page 3, without those acquisition related components, ROA of 0.98% and ROE of 9.61% would have been 1.01% and 9.96%, respectively, compared to 0.97% and 9.19% for the quarter ended December 31, 2021. ROA and ROE were 1.21% and 10.22% for the first three months of 2021.

A good indicator of the merger's positive impact on operating earnings is the efficiency ratio, as it neither includes provisions for losses on loans and unfunded commitments, nor is it impacted by changes in share counts. As shown in the reconciliation of GAAP to non-GAAP financial measures on page 3, the efficiency ratios excluding merger-related one-time and conversion costs were 57.46% and 53.63% for the quarters ended March 31, 2022 and December 31, 2021, respectively, as compared to 59.13% and 56.92%. The change over the prior quarter was primarily due to typical first quarter increases in salaries, benefits and professional services expenses. The significant improvement in operating leverage generated by the acquisition is evident in the decline in efficiency ratio from 64.60% in first quarter of 2021, which was not impacted by merger costs.

Loan balances of $2.202 billion at March 31, 2022 included an increase of $16.6 million in traditional commercial loans and a decrease of $70.6 million in Small Business Administration ("SBA") Paycheck Protection Program ("PPP") loans forgiven and paid off, resulting in a net decrease in loans of $53.8 million from December 31, 2021. First quarter loan originations of $49.8 million represented a six year peak for first quarter originations, and commercial line utilization increased to 38% of total commitments as of March 31, 2022, from 34% at December 31, 2021.

Credit quality remains strong, with non-accrual loans representing 0.35% of total loans as of March 31, 2022, compared to 0.37% at December 31, 2021. While classified loans did not change significantly from the prior quarter end, special mention loans decreased by $10.0 million, the majority of which was due to payoffs and upgrades to pass risk ratings. Reversals of $485 thousand to the allowance for credit losses on loans and $318 thousand to the allowance for credit losses on unfunded loan commitments resulted from improved economic forecasts.

Deposits grew by $52.8 million to $3.861 billion at March 31, 2022, compared to $3.809 billion at December 31, 2021, with most of the growth coming from non-interest bearing balances. Non-interest bearing deposits made up 51% of total deposits as of March 31, 2022 versus 50% as of December 31, 2021. The 0.06% cost of average deposits in the first quarter was unchanged from the fourth quarter of 2021 and compared to 0.07% in the first quarter of 2021. Additionally, as part of our liquidity management, the Bank maintained $180.0 million in deposits off-balance sheet with deposit networks at March 31, 2022.

All capital ratios were above well-capitalized regulatory requirements. The total risk-based capital ratio for Bancorp was 14.4% at March 31, 2022, compared to 14.6% at December 31, 2021. Bancorp's tangible common equity to tangible assets was 8.0% at March 31, 2022, compared to 8.8% at December 31, 2021 (refer to footnote 5 on page 7 for a discussion of this non-GAAP financial measure). The decline in tangible equity from December 31, 2021 was primarily due to the $37.3 million other comprehensive loss, net of taxes, related to significant increases in interest rates during the quarter. The Bank's total risk-based capital ratio was 14.3% at March 31, 2022, compared to 14.4% at December 31, 2021.

The Board of Directors declared a cash dividend of $0.24 per share on April 22, 2022, which represents the 68^th consecutive quarterly dividend paid by Bank of Marin Bancorp. The dividend is payable on May 13, 2022, to shareholders of record at the close of business on May 6, 2022.

Statement Regarding use of Non-GAAP Financial Measures

In this press release, Bancorp's financial results are presented in accordance with GAAP and refer to certain non-GAAP financial measures. Management believes that presentation of operating results using non-GAAP financial measures provides useful supplemental information to investors and facilitates the analysis of Bancorp's operating results and comparison of operating results across reporting periods. Management also uses non-GAAP financial measures to establish budgets and manage Bancorp's business. A reconciliation of the GAAP financial measures to comparable non-GAAP financial measures is presented below.

"We produced solid earnings in the first quarter, primarily due to new loan production paired with disciplined expense and liquidity management," said Tani Girton, EVP and Chief Financial Officer. "Our balance sheet and credit quality remain strong, enabling us to grow and deepen customer relationships in the year ahead."

Loans and Credit Quality

Loans totaled $2.202 billion at March 31, 2022 compared to $2.256 billion at December 31, 2021. Loan originations were $49.8 million for the first quarter of 2022, compared to $80.0 million in the fourth quarter of 2021 and $25.3 million in the first quarter of 2021 (excludes $119.5 million of SBA PPP loans originated in the first quarter of 2021). Non-PPP loan payoffs were $49.3 million in the first quarter 2022, compared to $72.8 million for the fourth quarter of 2021 and $34.6 million for first quarter of 2021. Loan payoffs in the first quarter were driven by investor commercial real estate assets outside the Bank's risk appetite or market area.

Bank of Marin and ARB originated a combined total of 3,556 loans amounting to $550.3 million in two rounds of SBA PPP loan financing. Of these amounts, as of March 31, 2022 there were 191 loans still outstanding totaling $40.6 million (net of $993 thousand in unrecognized fees and costs) compared to 368 loans outstanding at December 31, 2021 for a total of $111.2 million (net of $2.5 million in unrecognized fees and costs). In the first quarter of 2022, Bank of Marin recognized $1.5 million in PPP fees, net of costs, compared to $1.8 million in the prior quarter and $1.7 million in the same quarter of 2021.

During the onset of the pandemic, Bank of Marin granted payment relief for 269 loans totaling $402.9 million. As of March 31, 2022, two borrowing relationships with three loans totaling $23.6 million were continuing to benefit from payment relief. We monitor the financial situation of these clients closely and expect them to resume payments as the economy continues to recover.

Non-accrual loans totaled $7.7 million, or 0.35%, of the Bank's portfolio at March 31, 2022, compared to $8.4 million, or 0.37% at December 31, 2021, and $9.2 million, or 0.43%, a year ago. Non-accrual loans at March 31, 2022 and year end included two secured owner-occupied commercial real estate loans totaling $7.1 million, which were placed on non-accrual status in fourth quarter 2020. Classified loans totaled $36.5 million at March 31, 2022, compared to $36.2 million at December 31, 2021 and $26.4 million at March 31, 2021. Accruing loans past due 30 to 89 days totaled $2.3 million at March 31, 2022, compared to $1.7 million at December 31, 2021.

Net recoveries for both the first quarter of 2022 and fourth quarter of 2021 totaled $9 thousand, compared to $13 thousand in the first quarter a year ago. The ratio of allowance for credit losses to total loans was 1.02% at March 31, 2022 and December 31, 2021.

In the first quarter of 2022, we recorded a reversal of provision for credit losses on loans of $485 thousand, compared to a provision of $600 thousand in the prior quarter and a reversal of provision of $2.9 million in the first quarter of 2021. There was a reversal of provision for credit losses on unfunded commitments of $318 thousand in the first quarter of 2022, compared to a $210 thousand provision in the prior quarter and a $590 thousand reversal in the first quarter of 2021. Current quarter provision reversals were due primarily to the improvement in underlying economic forecasts.

Cash, Cash Equivalents and Restricted Cash

Total cash, cash equivalents and restricted cash were $170.9 million at March 31, 2022, compared to $347.6 million at December 31, 2021. The $176.7 million decrease was primarily due to the deployment of funds into investment securities, as noted below.

Investments

The investment securities portfolio totaled $1.746 billion at March 31, 2022, an increase of $235.9 million from December 31, 2021. The increase was primarily the result of securities purchases totaling $339.4 million, partially offset by maturities, calls, and paydowns totaling $48.0 million and an increase in unrealized losses of $53.0 million on available-for-sale investment securities primarily due to a sharp rise in market interest rates during the first quarter of 2022.

The Bank's strong liquidity position enabled the transfer of $357.5 million in available-for-sale securities to held-to-maturity classification, effective March 1, 2022, which serves to partially insulate other comprehensive income and equity from changes in interest rates. This transfer had no impact on net income, and future price changes on these securities due to changes in interest rates will not affect capital.

Deposits

Deposits totaled $3.861 billion at March 31, 2022, compared to $3.809 billion at December 31, 2021. The $52.8 million increase in deposits from the prior quarter is consistent with activity experienced throughout 2021 from larger business clients. The average cost of deposits remained consistent in the first quarter at 0.06%.

Earnings

Net Interest Income

Net interest income totaled $29.9 million in the first quarter of 2022, compared to $30.6 million in the prior quarter and $22.0 million in the first quarter a year ago. The $735 thousand decrease from the prior quarter was primarily attributable to changes in amortization and accretion on acquired loans, lower loan prepayment fees, lower PPP fee recognition and fewer days in the quarter, partially offset by higher average balances and yields on investment securities. The $7.9 million increase from the comparative quarter a year ago was reflective of the ARB merger, a larger allocation of the loan portfolio to higher rate loans, deployment of cash into investment securities, and costs associated with the early redemption of subordinated debt in the first quarter of 2021. Increases were partially offset by a lower average yield on the investment portfolio.

The tax-equivalent net interest margin was 2.96% in the first quarter, 3.03% in the prior quarter, and 3.19% in the first quarter of 2021. The decrease from the prior quarter was primarily due to changes in amortization and accretion on acquired loans, lower loan prepayment fees, lower PPP fee recognition, and a higher proportion of investment securities from balance sheet growth. Average yields on the non-PPP portion of the loan portfolio and the investment portfolio are beginning to reflect recent increases in interest rates, particularly commercial loans.

The decrease in tax-equivalent net interest margin from the same period a year ago was primarily attributed to a higher proportion of investment securities in the larger balance sheet associated with ARB's lower loan-to-deposit ratio and other deposit growth with average yields 74 basis points lower.

Non-Interest Income

Non-interest income totaled $2.9 million in the first quarter of 2022, compared to $2.7 million in the prior quarter and $1.8 million in the first quarter a year ago. The $148.0 thousand increase from the prior quarter was related to a payment on bank-owned life insurance. The $1.0 million increase from the first quarter of 2021 was mostly attributable to increased activity associated with the ARB acquisition.

Non-Interest Expense

Non-interest expense totaled $19.4 million in the first quarter of 2022, $19.0 million in the prior quarter and $15.4 million in the same quarter last year. The increase from the prior quarter was primarily due to seasonal increases related to annual incentives, share-based compensation and 401(k) contributions included in salaries and related benefits. Additionally, the cost of professional services increased due to audit work performed in the first quarter related to both the year-end financial statement audit and the acquisition. Increases were partially offset by a decrease in acquisition-related one-time data processing expenses. The largest increases over prior year first quarter expenses came from salaries and related benefits, which rose $2.3 million due to increased numbers of employees in acquired branch and loan offices, regularly scheduled annual merit and related increases, and lower deferred loan origination costs. Higher expenses across most other categories reflect the acquisition, including one-time and conversion costs of $547 thousand and additional amortization associated with the ARB core deposit intangible asset in the first quarter of 2022.

Share Repurchase Program

The Bancorp Board of Directors approved a share repurchase program on July 16, 2021 under which Bancorp may repurchase up to $25.0 million of its outstanding common stock through July 31, 2023. On October 22, 2021, the Board of Directors approved an amendment that increased the total authorization from $25.0 million to $57.0 million. Bancorp repurchased 23,275 shares totaling $877 thousand in the first quarter of 2022. From the start of this program, the Bancorp has repurchased 618,991 shares totaling $22.3 million as of March 31, 2022.

¹Interest income/expense is divided by actual number of days in the period times 360 days to correspond to stated interest rate terms, where applicable.
²Yields on available-for-sale securities are calculated based on amortized cost balances rather than fair value, as changes in fair value are reflected as a component of stockholders' equity. Investment security interest is earned on 30/360 day basis monthly.
³Yields and interest income on tax-exempt securities and loans are presented on a taxable-equivalent basis using the Federal statutory rate of 21 percent in 2022 and 2021.
⁴Average balances on loans outstanding include non-performing loans. The amortized portion of net loan origination fees is included in interest income on loans, representing an adjustment to the yield.
⁵2021 interest on subordinated debenture included $1.3 million in accelerated discount accretion from the early redemption of our last subordinated debenture on March 15, 2021.
