Rick Smith, President and CEO added; "The actions and activities that we pursued during the second half of last year continue to benefit Tri Counties Bank as evidenced by the significant reduction in noninterest expenses and our efficiency ratio. In addition, we rewarded shareholders with an increase in our dividend which now equates to $1.00 per year paid in quarterly amounts of $0.25. Our entire team has become more energized by the idea and growing ability to return to our offices, as well as the increasing level of market activity and opportunities that we continue to pursue."

SBA Paycheck Protection Program

In March 2020, the Small Business Administration ("SBA") Paycheck Protection Program ("PPP") was created to help small businesses keep workers employed during the COVID-19 crisis. In December 2020, the SBA announced plans for a second round of PPP lending with streamlined requirements for both borrowers and lenders. Effective Friday, January 15, 2021, Tri Counties Bank launched and began accepting applications via an improved on-line portal which allows borrowers to open a new account and submit PPP applications under the new PPP guidance.

The following is a summary of PPP loan related activity as of the periods indicated:

(dollars in thousands)	March 31, 2021		December 31, 2020		September 30, 2020		June 30, 2020

As of March 31, 2021, the total gross balance outstanding of PPP loans (Round 1) was $193,958,000 (948 loans) as compared to total round 1 PPP originations of $438,510,000. Included in the balance of outstanding PPP loans as of March 31, 2021 are approximately 115 loans totaling $75,669,000 that have been submitted to and are pending forgiveness by the SBA. In connection with the origination of these loans, the Company earned approximately $15,735,000 in loan fees, offset by deferred loan costs of approximately $763,000, the net of which will be recognized over the earlier of loan maturity (generally 24 months), repayment or receipt of forgiveness confirmation. As of March 31, 2021 there was approximately $2,358,000 in net deferred fee income remaining to be recognized. During the three months ended March 31, 2021, the Company recognized $4,854,000 in fees on round 1 PPP loans.

As of March 31, 2021, the total gross balance outstanding of PPP loans (Round 2) was $176,316,000 (1,536 loans) as compared to round 2 originations of the same amount. In connection with the origination of these loans, the Company earned approximately $7,850,000 in loan fees, offset by deferred loan costs of approximately $400,000, the net of which will be recognized over the earlier of loan maturity (generally 60 months), repayment or receipt of forgiveness confirmation. As of March 31, 2021 there was approximately $7,072,000 in net deferred fee income remaining to be recognized. During the three months ended March 31, 2021, the Company recognized $378,000 in fees on round 2 PPP loans. Based on application and approval activity occurring subsequent to March 31, 2021, management anticipates that total round 2 PPP originations will approximate 1,700 loans for $190,215,000 and which are expected generate $9,055,000 in fees from the SBA.

COVID Deferrals

Following the passage of the CARES Act legislation, the "Interagency Statement on Loan Modifications and Reporting for Financial Institutions Working with Customers Affected by the Coronavirus" was issued by federal bank regulators, which offers temporary relief from troubled debt restructuring accounting for loan payment deferrals for certain customers whose businesses are experiencing economic hardship due to Coronavirus. The applicable period for this relief, originally expected to expire on December 31, 2020, was extended through 2021 by way of the Consolidated Appropriations Act. The Company continues to closely monitor the effects of the pandemic on our loan and deposit customers. Our management team continues to be focused on assessing the risks in our loan portfolio and working with our customers to mitigate where possible, the risk of potential losses. Beginning in April 2020, the Company implemented loan programs to allow certain consumers and businesses impacted by the pandemic to defer loan principal and interest payments.

The following is a summary of COVID related loan customer modifications with outstanding balances as of March 31, 2021:

Total modifications	$	48,266	1.0	%	95.7	%	4.3	%	23.3	%	59.4	%	17.3	%

Since inception, total loan modifications associated with CARES Act legislation totaled approximately $439,346,000, of which $48,266,000 and $48,358,000 remained outstanding under their modified terms as of March 31, 2021 and December 31, 2020, respectively. Of the remaining balance outstanding as of March 31, 2021, $18,039,000 is related to second deferrals which are expected to conclude their modification period by August, 2021 and $1,845,000 is related to third deferrals expected to conclude in October, 2021. The Company has elected to forgo the CARES Act Relief guidance for loans totaling $2,160,000 and including all borrowers requesting third deferrals and has deemed such loans along with a limited number of other loans to be impaired under traditional TDR guidance. The remaining balance of loans with modified terms are expected to conclude their modification period

3

during fiscal 2021, however, as long as the current pandemic and recessionary economic conditions continue, it is anticipated that additional borrowers may request an initial or subsequent modification to their loan terms.

Management believes that its analysis of each borrower receiving a loan modification supports the ability of that borrower to return to their normal payment terms at the conclusion of the modification period. However, management determined that risk rating downgrades for each credit receiving a deferral modification was prudent until such time that the borrower's actual payment performance supported an upgrade to the pre-modification risk grade.

Balance Sheet

Total loans outstanding, excluding PPP, grew to $4.61 billion as of March 31, 2021, an increase of 5.2% over the same quarter of the prior year, and an annualized increase of 15.3% over the trailing quarter. Investments outstanding increased to $1.96 billion as of March 31, 2021, an increase of 56.7% annualized over the trailing quarter. Average earning assets to total average assets continued to increase to 92.7% at March 31, 2021, as compared to 92.4% and 90.4% at December 31, 2020, and March 31, 2020, respectively. The Company's loan to deposit ratio was 72.4% at March 31, 2021, as compared to 73.2% and 81.1% at December 31, 2020, and March 31, 2020, respectively.

Total shareholders' equity increased by $17,425,000 during the quarter ended March 31, 2021, primarily as a result of net income of $33,649,000, partially offset by a decrease in accumulated other comprehensive income of $9,319,000, and by $7,432,000 in cash dividends paid on common stock. As a result, the Company’s book value increased to $31.71 per share at March 31, 2021 as compared to $31.12 and $28.91 at December 31, 2020, and March 31, 2020, respectively. The Company’s tangible book value per share, a non-GAAP measure, calculated by subtracting goodwill and other intangible assets from total shareholders’ equity and dividing that sum by total shares outstanding, was $23.72 per share at March 31, 2021, as compared to $23.09 and $20.80 at December 31, 2020, and March 31, 2020, respectively.

Trailing Quarter Balance Sheet Change

Ending balances	As of March 31,		December 31,		$ Change		Annualized  % Change
(dollars in thousands)	2021		2020
Total assets	$	8,031,612	$	7,639,529	$	392,083	20.5	%
Total loans	4,966,977		4,763,127		203,850		17.1	%
Total loans, excluding PPP	4,606,133		4,436,357		169,776		15.3	%
Total investments	1,962,780		1,719,102		243,678		56.7	%
Total deposits	$	6,863,400	$	6,505,934	$	357,466	22.0	%

The growth of deposit balances continued during the first quarter of 2021, increasing by $357,466,000 or 22.0% annualized. The available liquidity from deposit growth was allocated to fund non-PPP loan and investment growth during the period, which increased by $169,776,000 and $243,678,000, or 15.3% and 56.7% annualized, respectively. Approximately $101,466,000 of the non-PPP loan growth during the quarter is attributed to an acquired pool of mortgage loans. New originations of the second round of PPP stimulus more than offset the decline in loans outstanding from the first round of PPP following SBA forgiveness, resulting in an increase of total loans during the first quarter of 2021 by $203,850,000 or 17.1% on an annualized basis as compared to the trailing quarter.

Average Trailing Quarter Balance Sheet Change

Qtrly avg balances	As of March 31,		As of December 31,		$ Change		Annualized  % Change

Total assets	$	7,808,912	$	7,570,952	$	237,960	12.6	%
Total loans	4,763,025		4,767,715		(4,690)		(0.4)	%

Total deposits	$	6,653,754	$	6,341,175	$	312,579	19.7	%

The decline in average total loans of $4,690,000, or (0.4)% on an annualized basis, during the first quarter of 2021 was inconsistent with the actual period end growth as compared to the trailing quarter of $203,850,000 or 17.1%, primarily due to the Company's loan originations occurring in the latter half of the quarter. In addition, the Company purchased a pool of single family residential mortgages totaling approximately $101,466,000 on the final day of the quarter. These purchased loans had at weighted average coupon of approximately 2.72% and an expected yield of approximately 2.48%. The significant growth in both ending and average balances of investment securities was a direct result of management's focus on the deployment of excess cash balances which remained elevated due to continued deposit growth during the quarter.

Total deposits	$	6,863,400	$	5,402,698	$	1,460,702	27.0	%

As discussed in previous quarters, the PPP program generated significant increases in volume during the twelve months ended March 31, 2021 for both loan and deposit balances. Other forms of stimulus payments have further elevated deposit levels during the same period. While excess deposit proceeds are ratably being allocated to the purchase of investment securities with medium term durations to improve overall margin, we expect to maintain above average levels of liquidity through 2021, as the economic impacts of COVID-19 and amount of future stimulus both remain uncertain. Investment securities increased to $1,962,780,000 at March 31, 2021, a change of $580,754,000 or 42.0% from $1,382,026,000 at March 31, 2020.

(1)Information is presented on a fully tax-equivalent (FTE) basis. The Company believes the use of this non-generally accepted accounting principles (non-GAAP) measure provides additional clarity in assessing its results, and the presentation of these measures on a FTE basis is a common practice within the banking industry.

Loans may be acquired at a premium or discount to par value, in which case, the premium is amortized (subtracted from) or accreted (added to) interest income over the remaining life of the loan. Generally, as time goes on, the effects of loan discount accretion and loan premium amortization decrease as the purchased loans mature or pay off early. Upon the early pay off of a loan, any remaining unaccreted discount or unamortized premium is immediately taken into interest income; and as loan payoffs may vary significantly from quarter to quarter, so may the impact of discount accretion and premium amortization on interest income. As a result of the uptick in interest rates, the prepayment rate of portfolio loans, inclusive of those acquired at a premium or discount, decreased during the first quarter of 2021. During the three months ended March 31, 2021, December 31, 2020, and March 31, 2020, purchased loan discount accretion was $1,712,000, $1,960,000, and $1,748,000, respectively.

(1)Fully taxable equivalent (FTE). All yields and rates are calculated using specific day counts for the period and year as applicable.

(2)Net interest spread is the average yield earned on interest-earning assets minus the average rate paid on interest-bearing liabilities.

(3)Net interest margin is computed by calculating the difference between interest income and interest expense, divided by the average balance of interest-earning assets.

Net interest income (FTE) during the three months ended March 31, 2021 increased $37,000 or 0.1% to $66,717,000 compared to $66,680,000 during the three months ended December 31, 2020. Over the same period, net interest margin decreased 5 basis points to 3.74% as compared to 3.79% in the trailing quarter. The 5 basis point decrease is attributed to a 2 basis point decrease in non-PPP loan yields, and a 7 basis point decline in investment security yields, which were 1.74% during the three months ended March 31, 2021, as compared to 1.81% during the trailing quarter. Conversely, those yield declines were partially offset due to a 2 basis point improvement in the rate paid on interest-bearing liabilities, and an increase in yields on the PPP loans, which earned 6.68% during the three months ended March 31, 2021, as compared to 5.59% during the trailing quarter. The quarterly increase in yield on PPP loans is due to an acceleration of deferred loan fee accretion resulting from approximately $140,024,000 in PPP loans being approved by the SBA for forgiveness during the quarter, as compared to $103,811,000 in forgiven loans during the last quarter of 2020.

As compared to the same quarter in the prior year, average loan yields, excluding PPP, decreased 21 basis points from 5.23% during the three months ended March 31, 2020, to 5.02% during the three months ended March 31, 2021. The 21 basis point decrease in yields on loans during the comparable three month periods ended March 31, 2021 and 2020 was entirely attributable to decreases in market rates and loan fees as the accretion of discounts from acquired loans added 16 basis points to loan yields in both quarterly periods. The index utilized in a significant portion of the Company’s variable rate loans, Wall Street Journal Prime, has remained unchanged at 3.25% since March 15, 2020, when it was reduced from 4.25%.

The decline in interest expense when compared to both the trailing quarter and the same quarter from the prior year was primarily attributed to reductions in the rates offered on deposit products. As a result, the cost of interest-bearing deposits, which decreased by 2 basis points as of March 31, 2021, to 0.10% from 0.12% at December 31, 2020.

In addition, the growth of noninterest-bearing deposits continues to benefit the average cost of total deposits as compared to historical periods. Specifically, the ratio of average total noninterest-bearing deposits to total average deposits was 39.9% and 40.3% as of March 31, 2021 and December 31, 2020, respectively, as compared to 34.4% in the quarter ended March 31, 2020. As a result, the average cost of total deposits decreased to 0.06% at March 31, 2021, compared to 0.19% in the same period of 2020.

Interest Rates and Loan Portfolio Composition

During the first quarter of 2020, several market interest rates, including many rates that serve as reference indices for variable rate loans, declined markedly from previous levels. This prolonged retraction in rates continued to apply downward pressure on the portfolio in the first quarter of 2021. As of March 31, 2021, the Company's loan portfolio consisted of approximately $4.97 billion in outstanding principal with a weighted average coupon rate of 4.20%, inclusive of the PPP program loans. Excluding PPP loans, the Company's loan portfolio has approximately $4.60 billion outstanding with a weighted average coupon rate of 4.46% as of March 31, 2021. Included in the March 31, 2021 loan total, exclusive of PPP loans, are variable rate loans totaling $3.01 billion of which 88.3% or $2.66 billion were at their floor rate. The remaining variable rate loans totaling $351.0 million, which carried a weighted average coupon rate of 4.91% as of March 31, 2021, are subject to further rate adjustment. If those remaining variable rate loans were to collectively, through future rate adjustments, be reduced to their respective floors, they would have a weighted average coupon rate of approximately 4.29% which would result in the reduction of the weighted average coupon rate of the total loan portfolio, exclusive of PPP loans, from 4.46% to approximately 4.41%.

As of December 31, 2020, the Company's loan portfolio consisted of approximately $4.80 billion in outstanding principal with a weighted average coupon rate of 4.35%, inclusive of the PPP program loans. Excluding PPP loans, the Company's loan portfolio has approximately $4.47 billion outstanding with a weighted average coupon rate of 4.60% as of December 31, 2020. Included in the December 31, 2020 loan total, exclusive of PPP loans, are variable rate loans totaling $3.02 billion of which 88.2% or $2.66 billion were at their floor rate. The remaining variable rate loans totaling $357.0 million, which carried a weighted average coupon rate of 5.03% as of December 31, 2020, are subject to further rate adjustment. If those remaining variable rate loans were to collectively, through future rate adjustments, be reduced to their respective floors, they would have a weighted average coupon rate of approximately 4.36% which would result in the reduction of the weighted average coupon rate of the total loan portfolio, exclusive of PPP loans, from 4.60% to approximately 4.55%.

Asset Quality and Credit Loss Provisioning

During the three months ended March 31, 2021, the Company recorded a reversal of provision for credit losses of $6,060,000, as compared to a provision expense of $4,850,000 for the trailing quarter, and a provision expense of $8,070,000 during the first quarter of 2020.

The following table presents details of the provision for credit losses for the periods indicated:

	Three months ended
(dollars in thousands)	March 31, 2021		December 31, 2020		September 30, 2020		June 30, 2020		March 31, 2020

Total provision for credit losses	$	(6,060)	$	4,850	$	7,649	$	22,244	$	8,070

The allowance for credit losses (ACL) was $85,941,000 as of quarter ended March 31, 2021, a net decrease of $5,906,000 over the immediately preceding quarter. More specifically, the reversal of allowance for credit losses of $6,240,000 consisted of $5,906,000 in changes relating to qualitative factors, loan volume and changes in credit quality associated with levels of classified, past due and non-performing loans, plus net recoveries totaling $334,000 during the quarter. The portfolio-wide qualitative indicator associated with the

7

forecast levels of US unemployment and the qualitative factors associated with portfolio concentration risks contributed approximately $3,540,000 and $2,954,000, respectively, to the reversal in credit reserves on loans as of March 31, 2021. Further reductions in required reserves of approximately $471,000 were associated with historical loss rates which have continued to remain low despite the recent economic uncertainty. California Unemployment factors, however, did not demonstrate a similar level of improvement and added approximately $834,000 to reserves as of March 31, 2021, as compared to December 31, 2020.

The Company utilizes a forecast period of approximately eight quarters and obtains the forecast data from publicly available sources as of the balance sheet date. This forecast data continues to evolve and included significant shifts in the magnitude of changes for both the unemployment and GDP factors leading up to the balance sheet date. Management noted that the majority of economic forecasts utilized in the ACL calculation seem to have rebounded in the current quarter, coinciding with the widespread availability of vaccines, continued easing of occupancy and social distancing restrictions, and continued government stimulus efforts.

Loans past due 30 days or more increased by $3,783,000 during the quarter ended March 31, 2021 to $10,550,000, as compared to $6,767,000 at December 31, 2020. Non-performing loans were $28,941,000 at March 31, 2021, an increase of $2,077,000 and $10,986,000, respectively, from $26,864,000 and $17,955,000 as of December 31, 2020, and March 31, 2020, respectively.

The following table illustrates the total loans by risk rating and their respective percentage of total loans for the periods presented.

	March 31,			% of Total Loans		December 31,			% of Total Loans		March 31,			% of Total Loans
(dollars in thousands)	2021					2020					2020

Loans past due 30+ days to total loans	0.21		%			0.14		%			0.67		%

The Company's loan portfolio for non-classified loans (loans graded special mention or better) remains generally consistent for the quarter ended March 31, 2021, as compared to the trailing quarter December 31, 2020, representing 98.8% and 99.0% of total loans outstanding, respectively. Loans risk graded special mention decreased by approximately $14,564,000 during the quarter ended March 31, 2021 as compared to the trailing quarter, while loans risk graded substandard increased by approximately $8,388,000 during the same periods. The change in both loan risk rating categories is largely due to the migration from special mention to substandard of three loans to separate borrowers, which totaled approximately $10,380,000. Only one of these loans is considered by management to be impaired as of March 31, 2021 and management believes that there is no ultimate risk of loss and therefore, no specific reserves have been recorded on this loan.

There were no additions to other real estate owned during the quarter ended March 31, 2021 and there was one sale for proceeds of approximately $576,000, which generated a gain of $51,000. As of March 31, 2021, other real estate owned consisted of six properties with a carrying value of $2,309,000.

For the periods presented in the table above and for purposes of calculating the "% of Loans Outstanding", PPP loans are included in the segment "Commercial and Industrial." PPP loans are fully guaranteed and therefore would not require any loss reserve allocation. Excluding the net outstanding balances of PPP loans from the ratio of the ACL to total loans results in a reserve ratio of approximately 1.87% as of March 31, 2021. In addition to the allowance for credit losses above, the Company has acquired various performing loans whose fair value as of the acquisition date was determined to be less than the principal balance owed on those loans. This difference represents the collective discount of credit, interest rate and liquidity measurements which is expected to be amortized over the life of the loans. As of March 31, 2021, the unamortized discount associated with acquired loans totaled $22,652,000 and if aggregated with the ACL would collectively represent 2.18% of total gross loans and 2.36% of total loans less PPP loans.

Non-interest Income

Total non-interest income	$	16,110	$	16,580	$	(470)	(2.8)	%

Non-interest income decreased $470,000 or 2.8% to $16,110,000 during the three months ended March 31, 2021 compared to $16,580,000 during the trailing quarter December 31, 2020. Mortgage loan origination volume declined slightly during the period ended March 31, 2021 as a result of an uptick in the interest rate environment, leading to a decrease in loans originated for sale and a $213,000 decrease in gain on sale of loans, as compared to the trailing quarter. Additionally, other non-interest income contributed $704,000 during the quarter ended March 31, 2021, a decrease of $431,000 from the trailing quarter. This decrease was primarily due

9

to an absence of a one-time death benefit totaling $498,000 realized during the quarter ended December 31, 2020. As an offset to these decreases in non-interest income, the change in valuation of mortgage servicing rights increased by $12,000 during the quarter as the expected duration of loans serviced for others extended, which represented an improvement of $388,000 as compared to the trailing quarter ended December 31, 2020.

The following table presents the key components of non-interest income for the periods indicated:

	Three months ended March 31,

Total non-interest income	$	16,110	$	11,820	$	4,290	36.3	%

In addition to the discussion above within the non-interest income for the three months ended March 31, 2021 and trailing December 31, 2020, deposit account related fee revenue has declined $777,000 or 19.2% during the three months ended March 31, 2021 when compared to the same period in the prior year as a result of the pandemic related stimulus which has bolstered average deposit balances and reduced the volume of transactions with fees such as minimum account balance charges and non-sufficient funds. As an offset, social distancing guidelines resulted in more online and debit card payment transactions benefiting ATM and interchange fees, which increased by $750,000 or 14.7% over the same quarter in the prior year.

Non-interest expense for the quarter ended March 31, 2021 decreased $4,127,000 or 9.0% to $41,618,000 as compared to $45,745,000 during the trailing quarter ended December 31, 2020. Salaries, net of deferred loan origination costs decreased by $999,000 to $15,511,000 for the three months ended March 31, 2021 due to a decrease in average full-time equivalent staff, in addition to a $404,000 increase in the total amount of deferred salaries attributed to loan production. Incentive compensation increased by $1,238,000 or 52.9% to $3,580,000 during the quarter ended March 31, 2021 as compared to the trailing period, as a result of the organic loan growth and strong overall Company performance during the quarter. Benefits and other compensation costs decreased by $3,382,000 to $6,239,000 during the quarter, primarily as a result of decreases in expenses associated with retirement obligations and group insurance costs.

Non-interest expense decreased by $3,131,000 or 7.0% to $41,618,000 during the three months ended March 31, 2021 as compared to $44,749,000 for the three months ended March 31, 2020. For reasons similar to those discussed above, salary and benefit expense decreased by $1,942,000 or 7.1% to $25,330,000 during the three months ended March 31, 2021 as compared to $27,272,000 for the same period in 2020. During the three months ended March 31, 2021, the 140 decline in average full-time equivalent employees benefited employee salary expense by $1,591,000, and increases in capitalized salary costs from loan origination activities reduced the expense an additional $445,000, respectively, as compared to the quarter ended March 31, 2020. Miscellaneous expenses also decreased during the period by $581,000 or 19.8% to $2,349,000 as compared to the same period in 2020, which is primarily attributed to precautionary reductions in travel and outside training expenses associated that began late in the first quarter of 2020.

Offsetting these decreases were larger regulatory assessment and insurance costs, which increased to a normalized quarterly rate of $612,000 during the period, an increase of $517,000 as compared to the first quarter of 2020, during which the FDIC issued a regulatory assessment credit of $437,000.

Provision for Income Taxes

The Company’s effective tax rate was 28.4% for the year ended March 31, 2021, as compared to 25.8% for the year ended December 31, 2020. The reduced effective tax rate in the prior year was made possible through the provisions of the Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”) which provided the Company with an opportunity to file amended tax returns and generate proposed refunds of approximately $805,000. Other differences between the Company's effective tax rate and applicable federal and state statutory rates are due to the proportion of non-taxable revenue and low income housing tax credits as compared to the levels of pre-tax earnings.

TRICO BANCSHARES—NON-GAAP FINANCIAL MEASURES

(Unaudited. Dollars in thousands)

In addition to results presented in accordance with generally accepted accounting principles in the United States of America (GAAP), this press release contains certain non-GAAP financial measures. Management has presented these non-GAAP financial measures in this press release because it believes that they provide useful and comparative information to assess trends in the Company's core operations reflected in the current quarter's results, and facilitate the comparison of our performance with the performance of our peers. However, these non-GAAP financial measures are supplemental and are not a substitute for any analysis based on GAAP. Where applicable, comparable earnings information using GAAP financial measures is also presented.

April 2021 Investor Presentation AGENDA • Most Recent Quarter Recap • Company Overview • Lending Overview • Deposit Overview • Financials 3

April 2021 Investor Presentation MOST RECENT QUARTER HIGHLIGHTS 4 Consistent Profitability • Pre-tax pre-provision return on average assets and average equity were 2.13% and 17.65%, respectively, for the quarter ended March 31, 2021, and 1.96% and 16.33%, respectively, for the trailing quarter. • Expense management strategies and disciplined business practices continue to result in improved operating performance. Our efficiency ratio improved to 50.4% compared to 55.1% for the current and trailing quarters, respectively. • Mortgage origination and sale activity and PPP fee accretion continued to positively contribute to earnings. Growth to Drive Results • Well positioned balance sheet and relative stock price to capitalize on opportunities as they arise. • Organic loan growth exceeded 6% on an annualized basis for the quarter. • Actively engaged in discussions with experienced leaders in various California communities with the intent to extend our historical Northern and Central California commercial lending footprint through new loan production offices. Net Interest Income and Margin • Net interest margin (FTE) was 3.74% for Q1 2021, compared to 3.79% for Q4 2020 and 4.34% in Q1 2020. • Growth in non-interest-bearing deposits continue to drive improved funding costs where total cost of deposits was 0.06% in Q1 2021 compared to 0.19% Q1 2020. • Accretion of PPP loan fees and multifamily loan growth are poised to buoy net interest income as excess balance sheet liquidity deployment occurs in and support of net interest margin builds. Credit Quality • Continued net recoveries and improving outlook key to a $6.2MM release in loan loss reserves, at 1.73% of total loans, or 1.87% when excluding PPP loans. • Nonperforming assets to total assets held at 0.39%, and the Bank’s Criticized and Classified portfolio as a percent of total loans declined to 4.1% in Q1 20201 versus 4.4% in Q4 2020. • Net recoveries for the three and twelve months ended March 31, 2021 were $334,000 and $82,000, respectively. Diverse Deposit Base • Non-interest-bearing deposits comprise 40.3% of total deposits, and deposits form 96.8% of total liabilities. Capital and Liquidity Strength • Over a 28-year history of quarterly cash dividends with periodic increases as most recently evidenced by the increase to the equivalent to $1.00 per year paid in quarterly amounts of $0.25. • Strength in core earnings and continued market capture key to self-financed and self-funded growth. • We remain well capitalized across all regulatory capital ratios. • Active share repurchase program with demonstrated utilization.
