Announces $0.24 Dividend

Bank of Marin Bancorp, "Bancorp" (NASDAQ:BMRC), parent company of Bank of Marin, "Bank," announced earnings of $9.7 million in the fourth quarter of 2021, compared to $5.3 million in the third quarter of 2021 and $8.1 million in the fourth quarter of 2020. Diluted earnings per share were $0.61 in the fourth quarter of 2021, compared to $0.35 in the prior quarter and $0.60 the same quarter a year ago. Annual earnings were $33.2 million in 2021 compared to $30.2 million in 2020. Diluted earnings per share were $2.30 for the year ended December 31, 2021, compared to $2.22 per share for the year ended December 31, 2020.

"As illustrated by our fourth-quarter earnings, we are poised to reap the benefits of better scale gained through our acquisition of American River Bankshares with most of the one-time costs behind us and the increase in our balance sheet size," said Tim Myers, President and Chief Executive Officer. "Improving economic forecasts led to reduced credit loss provisions in 2021 when compared to the prior year, and key hires helped us build substantial momentum as we finished the year with robust loan production across our Northern California footprint. We expect that traction to drive continued growth and strong results for our shareholders in 2022."

Bancorp also provided the following highlights for the fourth quarter and year ended December 31, 2021:

Merger-related one-time and conversion costs reduced net income by $791 thousand, net of taxes, or 5 cents per share in the fourth quarter and by $4.9 million, net of taxes, or 34 cents per share for the year ended December 31, 2021. Return on average assets ("ROA") and return on average equity ("ROE") ratios were also significantly impacted by provisions for credit losses on acquired loans and shares issued in conjunction with the merger. As shown in the reconciliation of GAAP to non-GAAP financial measures on pages 2 and 3, without those acquisition related components, year-to-date ROA of 0.94% and ROE of 8.43% would have been 1.08% and 9.67%, respectively, compared to 1.04% and 8.60% for the same periods in 2020. For the quarter ended December 31, 2021, ROA and ROE were 0.90% and 8.50%, respectively, compared to 0.56% and 4.99%, respectively, in the prior quarter. The comparable non-GAAP ROA and ROE were 0.97% and 9.19%, respectively, for the quarter ended December 31, 2021, versus 0.98% and 8.69% in the prior quarter.

Loans increased $167.1 million in 2021, or 8%, to $2.256 billion at December 31, 2021, from $2.089 billion at December 31, 2020. Year-over-year growth was largely attributable to the August 6, 2021 acquisition of $419.4 million from American River Bank. Non-PPP loan originations of $181.7 million for the year were concentrated in commercial and real estate loans and compared to $165.5 million in 2020. Payoffs included $218.1 million non-PPP loans compared to $169.2 million in 2020. In 2021, PPP loan originations were $136.2 million and PPP loans forgiven and paid off were $328.5 million.

Bank of Marin made significant talent investments in the fourth quarter. We hired a Commercial Banking Sales Manager, a new role at the Bank, to oversee and direct commercial banking growth across the enterprise. This hire also has significant experience in the Sacramento area, and we added two new commercial bankers to support our anticipated growth in that market.

Credit quality remains strong, with non-accrual loans representing 0.37% of the Bank's loan portfolio as of December 31, 2021, compared to 0.36% as of September 30, 2021. Over the course of 2021, we recorded net reversals of $1.4 million and $992 thousand to our respective allowances for credit losses on loans and unfunded commitments, compared to provisions of $4.6 million and $1.6 million, respectively, in 2020. 2021 activity included the effects of the business combination with American River Bank and ongoing improvements in the underlying economic forecasts. In 2020, the current expected credit loss model was implemented at year end. During the first three quarters, allowance for credit losses were calculated under the incurred loss model and included significant qualitative adjustments for uncertainties associated with the pandemic.

Deposits grew $1.304 billion, or 52%, to $3.809 billion at December 31, 2021, compared to $2.504 billion at December 31, 2020. Growth was comprised of $790.0 million related to the August 6, 2021 American River Bank acquisition, new accounts and growth in the existing customer base. Non-interest bearing deposits grew by $555.6 million, or 41%, in 2021 and made up 50% of total deposits at year end. Cost of deposits remained low at 0.07% for the full year of 2021, down from 0.11% in 2020. Additionally, the Bank maintained $173.1 million in deposits off-balance sheet with deposit networks at December 31, 2021 as part of our liquidity management.

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 pages 2 and 3, the efficiency ratio excluding merger-related one-time and conversion costs of 53.63% for the quarter ended December 31, 2021, improved from 56.02% and 55.93% in the quarters ended September 30, 2021 and December 31, 2020, respectively.

All capital ratios were above regulatory requirements for a well-capitalized institution. The total risk-based capital ratio for Bancorp was 14.6% at December 31, 2021 and 16.0% at December 31, 2020. Tangible common equity to tangible assets declined to 8.8% at December 31, 2021 from 11.3% at December 31, 2020 primarily due to share repurchases and growth in legacy Bank of Marin deposits (refer to footnote 5 on page 7 for definition of this non-GAAP financial measure). The total risk-based capital ratio for the Bank was 14.4% at December 31, 2021 and 15.8% at December 31, 2020.

Bank of Marin Bancorp repurchased 149,983 shares totaling $5.6 million in the fourth quarter of 2021 for a cumulative total of 1,117,666 shares and $40.8 million in 2021.

The Board of Directors declared a cash dividend of $0.24 per share on January 21, 2022. This is the 67^th consecutive quarterly dividend paid by Bank of Marin Bancorp. The cash dividend is payable on February 11, 2022 to shareholders of record at the close of business on February 4, 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.

"Thanks to sound underwriting practices, pandemic-driven downgrades within our portfolio have been manageable. We continue to help our customers navigate this environment while maintaining strong capital, liquidity and overall credit quality," said Tani Girton, EVP and Chief Financial Officer. "The American River addition strengthened our relationship banking model and industry-leading low-cost deposit base, leaving us even better positioned financially and strategically to pursue growth opportunities in the year ahead."

Loans and Credit Quality

Loans decreased by $61.4 million in the fourth quarter and totaled $2.256 billion at December 31, 2021. Non-PPP-related loan originations were $80.0 million and $181.7 million for the fourth quarter and full year of 2021, compared to $43.1 million and $165.5 million for the same periods in 2020. Non-PPP loan payoffs were $72.8 million and $218.1 million in the fourth quarter and full year of 2021, compared to $44.9 million and $169.2 million for the same periods of 2020. Loan payoffs in the fourth quarter and full year 2021 consisted largely of commercial borrower real estate asset sales and cash paydowns as part of ongoing deleveraging. Approximately $54 million in PPP loans were forgiven in the fourth quarter and $329 million over the course of the year.

Bank of Marin and American River Bank 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 December 31, 2021 there were 368 loans outstanding totaling $111.2 million (net of $2.5 million in unrecognized fees and costs). In 2021 and 2020 respectively, Bank of Marin recognized $8.3 million and $3.8 million in PPP fees, net of costs.

During the onset of the pandemic, Bank of Marin granted payment relief for 269 loans totaling $402.9 million. As of December 31, 2021, only 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 $8.4 million, or 0.37% of the Bank's loan portfolio at December 31, 2021, compared to $8.4 million, or 0.36%, at September 30, 2021 and $9.2 million, or 0.44%, a year ago. Non-accrual loans at 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 of 2020. Loans classified substandard totaled $36.2 million at December 31, 2021, $19.0 million at September 30, 2021, and $25.8 million at December 31, 2020. The increase in substandard loans in the fourth quarter of 2021 was primarily due to one borrowing relationship with two secured non-owner-occupied commercial real estate loans that were negatively affected by the pandemic. Classified loans included one $114 thousand loan acquired from American River Bank with a doubtful risk rating as of December 31, 2021, which is well-secured by real estate collateral. There were no loans classified doubtful at December 31, 2020. Accruing loans past due 30 to 89 days totaled $1.7 million at December 31, 2021, compared to $1.4 million at September 30, 2021 and $1.8 million a year ago.

Net recoveries for the fourth quarter of 2021 totaled $9 thousand compared to net recoveries of $9 thousand last quarter and $13 thousand in the fourth quarter of 2020. Net recoveries totaled $93 thousand for the year ended December 31, 2021, compared to net charge-offs of $1 thousand in 2020. The ratio of allowance for credit losses to loans was 1.02% at December 31, 2021, 0.97% at September 30, 2021 and 1.10% at December 31, 2020.

In the fourth quarter of 2021, we recorded a provision for credit losses on loans of $600 thousand resulting from adjustments to qualitative risk factors primarily impacted by recent changes in executive leadership, senior lending positions, and integration of the American River Bank lending staff and loan portfolio as well as further refinements to the discounted cash flow assumptions applied to acquired loans within the allowance model. However, there was a reduction in qualitative risk factors due to a decline in the volume of loans downgraded to substandard classification, fewer delinquencies, and the elimination of an allowance related to a commercial real estate loan that had been individually analyzed for potential credit losses in the previous periods and paid off in the fourth quarter. Additionally, there was an overall improvement in the underlying economic forecasts. In the fourth quarter of 2021, we also recorded a provision of $210 thousand for losses on unfunded commitments due to the adjustments to qualitative risk factors mentioned above.

Cash, Cash Equivalents and Restricted Cash

Cash, cash equivalents and restricted cash totaled $347.6 million at December 31, 2021, compared to $584.7 million at September 30, 2021. The $237.1 million decrease was primarily due to the deployment of funds into investment securities, as noted below.

Investments

The investment portfolio totaled $1.510 billion at December 31, 2021, an increase of $350.0 million from September 30, 2021 and an increase of $1.008 billion from December 31, 2020. The increase in the fourth quarter of 2021 was primarily the result of securities purchases totaling $416.9 million, partially offset by maturities, calls, paydowns, and sales totaling $51.8 million. The year-over-year increase was due to purchases of $925.6 million and acquisition of $297.8 million in securities related to the merger, partially offset by maturities, calls, paydowns and sales totaling $188.4 million.

Deposits

Deposits totaled $3.809 billion at December 31, 2021, compared to $3.728 billion at September 30, 2021 and $2.504 billion at December 31, 2020. The $80.9 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 fourth quarter at 0.06%.

Earnings

Net Interest Income

Net interest income totaled $30.6 million in the fourth quarter of 2021, compared to $27.8 million in the prior quarter and $23.6 million in the same quarter a year ago. The $2.9 million increase from the prior quarter was primarily related to an increase of $1.5 million in loan interest and $1.6 million in investment securities interest income. We recognized $1.8 million in fees, net of cost on SBA PPP loans in the current quarter as compared to $2.3 million in prior quarter, and $1.0 million in the same quarter a year ago. Quarter-over-quarter, average loan balances increased $80.2 million to $2.3 billion and the yield increased 10 basis points to 4.43%, mostly due to lower rate PPP loans paying off. While average yields on investment securities decreased 36 basis points in the fourth quarter to 1.65%, the deployment of cash that resulted in a $565.3 million increase in average investments to $1.4 billion significantly contributed to the increase in quarterly net interest income.

The $7.0 million net interest income increase over the same quarter last year was primarily due to higher loan balances and a 52 bps higher average loan yield driven by accelerated fee recognition from PPP loan payoffs. Additionally, incremental balances in the investment portfolio, while pushing the average yield lower, added $2.4 million to net interest income. Fourth quarter average interest-earning assets increased $1.3 billion versus the same quarter last year, primarily due to the American River Bank acquisition, leading to a $172.9 million increase in average loans and a $911.7 million increase in average investment securities. Average interest-bearing deposit balances increased $720.9 million.

The tax-equivalent net interest margin was 3.03% for the fourth quarter of 2021, compared to 3.15% in the prior quarter and 3.40% in the fourth quarter of 2020. The 12 basis points decrease from the prior quarter was primarily due to a higher proportion of investment securities in the growing balance sheet. The positive impact of SBA PPP loans to the fourth quarter of 2021 net interest margin was 2 basis points lower than the prior quarter. The 37 basis points decrease from the same quarter a year ago was also largely due to the shift in balance sheet composition. The SBA PPP loans improved the fourth quarter of 2021 net interest margin by 11 basis points as compared to lowering the fourth quarter of 2020's net interest margin by 13 basis points.

Net interest income totaled $105.0 million and $96.7 million in 2021 and 2020, respectively. The $8.3 million increase in 2021 was primarily due to higher average loan and investment balances and higher PPP loan income. The tax-equivalent net interest margin decreased 38 basis points to 3.17% in 2021, from 3.55% in 2020 for the reasons mentioned above. The SBA PPP loans improved the 2021 net interest margin by 10 basis points as compared to lowering the 2020 net interest margin by 6 basis points.

Non-Interest Income

Non-interest income totaled $2.7 million in the fourth quarter of 2021, compared to $3.6 million in the third quarter of 2021 and $1.8 million in the fourth quarter of 2020. The decrease from prior quarter was largely attributed to the collection of $1.1 million in benefits on bank-owned life insurance policies in the third quarter of 2021. The $892 thousand increase in the fourth quarter of 2021 compared to the fourth quarter a year ago was spread across most categories and resulted from increased activity largely related to the expanded deposit base.

Non-interest income totaled $10.1 million in 2021, a $1.5 million increase from $8.6 million in 2020. The increase was primarily due to the $1.1 million in benefits collected on bank-owned life insurance policies and changes in other categories as noted above. Wealth Management and Trust Services income increased by $371 thousand due to increases in specialized trust administration matters, new accounts and price appreciation of assets under management. In addition, investment securities sales produced a net loss of $16 thousand in 2021 compared to net gains of $915 thousand in 2020.

Non-Interest Expense

Non-interest expense totaled $19.0 million in the fourth quarter of 2021, compared to $22.7 million in prior quarter and $14.2 million in the same quarter last year. Decreases from prior quarter of $2.4 million in salaries and benefits and $1.8 million in professional services were largely due to one-time merger related costs in the third quarter. Additionally, salaries and benefits expense included offsetting changes related to higher deferred loan origination costs and year-end true-ups to incentives. When compared to the fourth quarter of 2020, increases came largely from acquisition-related one-time and conversion costs, acquisition-related expense growth across categories, and 2021 true-ups to incentive and vacation accruals.

Non-interest expense increased $14.1 million to $72.6 million in 2021 from $58.5 million in 2020. The largest increase of $6.5 million came from acquisition related one-time and conversion costs. In addition to $3.0 million in one-time merger cost, salaries and related benefits rose another $4.5 million due to increased numbers of employees, regularly scheduled annual merit and related increases, and lower deferred loan origination costs. Professional services included $817 thousand more in consulting expenses for PPP loan forgiveness application processing, investment advisory services, and legal costs. Data processing increased by an additional $828 thousand primarily due to increases core processing and mobile banking systems charges, and other categories increased due to the larger size of the bank. Charitable contributions decreased due to supplemental contributions in 2020 related to the pandemic.

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 149,983 shares totaling $5.6 million in the fourth quarter of 2021 for a cumulative total of 1,117,666 shares and $40.8 million in 2021 under the current and prior authorizations.

¹ Interest 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.
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.
⁵ 2021 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.
⁶ Average balances and rate consider $13.9 million in FHLB borrowings acquired from American River Bank that were redeemed on August 25, 2021.
