BANK OF MARIN BANCORP REPORTS EARNINGS OF $5.1 MILLION

NOVATO, CA, October 23, 2017 - Bank of Marin Bancorp, "Bancorp" (NASDAQ: BMRC), parent company of Bank of Marin, "Bank," announced earnings of $5.1 million in the third quarter of 2017, compared to $5.2 million in the second quarter of 2017 and $7.0 million in the third quarter of 2016. Diluted earnings per share were $0.83 in the third quarter of 2017, compared to $0.84 in the prior quarter and $1.14 in the same quarter last year. Earnings for the first nine months of 2017 totaled $14.9 million, compared to $17.4 million in the same period last year. Diluted earnings per share were $2.41 and $2.86 in the first nine months of 2017 and 2016, respectively. Earnings in the third quarter and the first nine months of 2017 included $495 thousand in expenses related to the pending Bank of Napa acquisition, without which diluted earnings per share would have been $0.88 and $2.46, respectively. Additionally, earnings in the third quarter and first nine months of 2016 were $0.35 per share higher than the same periods of 2017 due to the large recovery of a problem credit and early payoff of an acquired loan in 2016.

“Our strong third quarter results show that we continue to be successful growing loans and deposits organically. We are also on target to complete our acquisition of Bank of Napa,” said Russell A. Colombo, President and Chief Executive Officer. “We are executing on our strategic plan to generate prudent and sustainable growth, build long-term client relationships and increase shareholder value.”

Bancorp also provided the following highlights for the third quarter of 2017:

•

Beginning on October 8, 2017, much of the North Bay region of Northern California was struck by massive wildfires. Management is closely monitoring the situation, continues to respond to the immediate needs of customers and employees, and has made contributions to several disaster relief organizations. It is not possible at this time to assess the full scope of this disaster or its impact on our customers and those of Bank of Napa.


•	On July 31, 2017, Bancorp entered into a definitive agreement to acquire Bank of Napa. The transaction is expected to close in November of 2017. Upon consummation of the transaction, the Bank will have approximately $2.4 billion in assets and operate twenty-three branches in San Francisco, Marin, Sonoma, Napa and Alameda counties.


•	On October 16, 2017, James S. Kimball, formerly of Wells Fargo, joined the Bank as an executive vice president in the newly created position of Chief Operating Officer. Mr. Kimball is responsible for Commercial Banking, Retail Banking, Wealth Management & Trust, and Marketing. His addition strengthens a management team focused on a growth trajectory for the Bank.


•	Total deposits increased $50.4 million in the third quarter to $1,891.0 million. Non-interest bearing deposits represented 48.9% of total deposits and the cost of total deposits for the quarter was 0.07%, up one basis point from last quarter and down one basis point from last year.

•

Gross loans totaled $1,524.4 million at September 30, 2017 and increased $32.9 million from $1,491.5 million at June 30, 2017. New loan volume of $42.3 million in the third quarter of 2017 was $14.0 million lower than the same quarter of 2016, which was mostly offset by a $13.4 million decrease in loan payoffs. The increase in the third quarter was partially due to the purchase of $7.0 million in high quality tenancy-in-common loans. Our current pipeline is slightly larger than last year at this time, and should translate into loan growth throughout the remainder of 2017 and into 2018.


•	Excellent credit quality remains the hallmark of the Bank's culture. Non-accrual loans represented 0.09% of total loans as of September 30, 2017. There was no provision for loan losses recorded in the quarter. The Bank recorded a $100 thousand provision for losses on off-balance sheet commitments primarily related to an increase in total commitments during the quarter.


•	All capital ratios are well above regulatory requirements for a well-capitalized institution. Total risk-based capital ratio for Bancorp was 15.1% at September 30, 2017, compared to 15.0% at June 30, 2017. Tangible common equity to tangible assets was 11.0% at September 30, 2017, compared to 11.1% at June 30, 2017.


•	The Board of Directors declared a cash dividend of $0.29 per share on October 20, 2017. This represents the 50^th consecutive quarterly dividend paid by Bank of Marin Bancorp. The dividend is payable on November 10, 2017, to shareholders of record at the close of business on November 3, 2017.

Loans and Credit Quality

Third quarter loan originations totaled $42.3 million, compared to $55.5 million last quarter and $56.3 million in the same quarter last year. Loan payoffs for the quarter were $25.2 million, down from $48.1 million in the second quarter and $38.6 million in the same quarter last year. The largest portion of payoffs in the current quarter came from the successful completion of construction projects and the sale of assets underlying other loans.

Non-accrual loans totaled $1.3 million, or 0.09% of the loan portfolio at September 30, 2017, compared to $1.2 million, or 0.08% at June 30, 2017, and $540 thousand, or 0.04% a year ago. Classified loans totaled $33.5 million at September 30, 2017, compared to $29.3 million at June 30, 2017 and $22.6 million at September 30, 2016. The increase during the quarter was due to draws on commitments to existing classified borrowers. Accruing loans past due 30 to 89 days totaled $205 thousand at September 30, 2017, compared to $393 thousand at June 30, 2017 and $160 thousand a year ago.

There was no provision for loan losses recorded in the third quarter of 2017, which is consistent with the prior quarter as the level of reserves was deemed appropriate for the portfolio. A $1.6 million reversal of the provision for loan losses in the third quarter of 2016 resulted from a $2.2 million charged-off principal recovery on a problem credit. Net recoveries were $16 thousand in the third quarter of 2017, compared to $13 thousand in the prior quarter and $2.2 million in the same quarter a year ago. The ratio of loan loss reserves to loans was 1.00% at September 30, 2017, compared to 1.02% at June 30, 2017 and 1.07% at September 30, 2016. At September 30, 2017, total loan loss reserves to loans excluding acquired loans was 1.05%.

Investments

The investment portfolio increased $11.3 million from the prior quarter to $413.2 million. The increase was primarily due to purchases of $41.8 million, partially offset by principal paydowns and maturities during the third quarter. Given the interest rate environment, the Bank opted to leave excess cash at the Federal Reserve Bank as a short-term investment alternative.

Deposits

Total deposits increased to $1,891.0 million at September 30, 2017, compared to $1,840.5 million at June 30, 2017. We continue to see increases from large commercial clients' operational cash flows. These increases include the placement by existing clients of funds from asset sales that will be distributed to the beneficiaries of trusts or transitioned into real estate or other investments.

Earnings

“Our earnings, excluding acquisition-related expenses, reflect a very healthy $0.88 per diluted share,” said Tani Girton, Chief Financial Officer. “The strength of our earnings is a testament to our ability to grow loans and deposits and maintain profitablility while investing in the future of the Bank.”

Net interest income totaled $18.8 million in the third quarter of 2017, compared to $18.3 million in the prior quarter. The increase in net interest income from the prior quarter reflects an increase of $74.3 million in average earnings assets, partially offset by lower acquired loan income as shown in the table below.

Net interest income of $18.8 million in the third quarter of 2017 decreased by $600 thousand from $19.4 million for the same quarter last year. The decrease was primarily due to a $1.4 million interest recovery on a problem credit in the third quarter of 2016. Additionally, acquired loan income decreased by $486 thousand in the third quarter of 2017 compared to the same period last year. These declines were partially offset by a $97.4 million increase in average earning assets. Higher yields on investment securities and interest-bearing cash, and upward repricing of variable rate loans also positively impacted interest income for the current quarter.

Net interest income totaled $54.7 million in the first nine months of 2017, compared to $55.2 million for the same period in 2016. The $472 thousand decline was driven by the decrease in acquired loan income and the interest recovery mentioned above, partially offset by a $78.2 million increase in average earning assets compared to the same period in 2016. Additionally, higher yields on investment securities and interest-earning cash, a decline in the cost of funds and the upward repricing of variable rate loans positively impacted net interest income.

The tax-equivalent net interest margin was 3.77% in the third quarter of 2017, compared to 3.85% in the prior quarter and 4.05% in the same quarter a year ago. The eight basis point decrease in the third quarter of 2017 compared to the prior quarter was primarily due to an increase in interest-earning cash that is lower yielding than loans and investment securities. The twenty-eight basis point decline compared to the third quarter of 2016 is primarily due to the impact of the interest recovery upon the payoff of a problem loan in 2016 and decrease in acquired loan income mentioned in the preceding paragraphs.

Loans obtained through the acquisition of other banks are classified as purchased credit impaired ("PCI") or non-PCI loans and are recorded at fair value at acquisition date. For acquired loans not considered credit impaired, the level of accretion varies due to maturities and early payoffs. Accretion on PCI loans fluctuates based on changes in cash flows expected to be collected. Gains on payoffs of PCI loans are recorded as interest income when the payoff amounts exceed the recorded investment.

As our acquired loans from prior acquisitions continue to pay off, we expect the accretion on these loans to continue to decline. Accretion and gains on payoffs of purchased loans recorded to interest income were as follows:

¹ Accretable yield on PCI loans totaled $1.2 million, $1.3 million and $1.6 million at September 30, 2017, June 30, 2017 and September 30, 2016, respectively.

² Unaccreted purchase discounts on non-PCI loans totaled $1.3 million, $1.4 million and $1.9 million at September 30, 2017, June 30, 2017 and September 30, 2016, respectively.

Non-interest income totaled $2.1 million in both the second and third quarters of 2017, and in the third quarter of 2016. Non-interest income totaled $6.3 million in the first nine months of 2017, compared to $6.7 million for the same period of 2016. The decrease primarily relates to $394 thousand in gains on the sale of investment securities in 2016.

Non-interest expense totaled $13.0 million in the third quarter of 2017, $12.6 million in the prior quarter, and $11.9 million in the same quarter a year ago. The increase from the prior quarter was primarily due to expenses associated with the pending Bank of Napa acquisition, which totaled $495 thousand. In addition, we recognized a $100 thousand provision for losses on off-balance sheet commitments, compared to a $208 thousand reversal of provision in the prior quarter. The provision resulted from an increase in total commitments during the quarter.

The increase from the same quarter a year ago was primarily due to higher salaries and benefits related to filling open positions and incentive bonuses, as well as acquisition-related expenses.

Non-interest expense totaled $38.7 million in the first nine months of 2017, compared to $35.9 million in the same period of 2016. The increase was primarily due to higher salaries and benefits related to filling open positions, which resulted in additional incentive bonuses, stock-based compensation and 401(k) employer match. The search for qualified employees resulted in recruiting fees, which contributed to an increase in other expenses. Occupancy and equipment expense also increased, primarily due to higher rent and maintenance costs.

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 35 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.
