Enterprise Bancorp, Inc. Announces Third Quarter Financial Results

LOWELL, MA, October 21, 2021 (GLOBE NEWSWIRE) - Enterprise Bancorp, Inc. (NASDAQ: EBTC), parent of Enterprise Bank, announced net income for the three months ended September 30, 2021 of $9.8 million, or $0.81 per diluted common share, compared to $10.3 million, or $0.87 per diluted common share, for the three months ended September 30, 2020. Net income for the nine months ended September 30, 2021 amounted to $31.3 million, or $2.60 per diluted common share, compared to $21.6 million, or $1.81 per diluted common share, for the nine months ended September 30, 2020.

As previously announced on October 19, 2021, the Company declared a quarterly dividend of $0.185 per common share to be paid on December 1, 2021 to shareholders of record as of November 10, 2021.

Chief Executive Officer Jack Clancy commented, "I am pleased to report our strong third quarter and year-to-date financial results. Our financial results during the third quarter of 2021 were derived primarily from strong net interest income, which included $4.9 million in PPP loan income, and a lower provision for credit losses, partially offset by higher non-interest expense. During the quarter we reduced future interest expense by paying off a borrowing and terminating interest-rate hedges, resulting in a loss on termination of $1.8 million."

Mr. Clancy continued, "Our balance sheet remains characterized by high liquidity with interest-earning deposits with banks amounting to $606.3 million or 14% of total assets at September 30, 2021. During the third quarter of 2021 we invested significantly in our bond portfolio increasing total investments to $819.2 million at September 30, 2021, compared to $634.0 million at June 30, 2021. Despite the increase, our liquidity remained elevated as we experienced $156.2 million in PPP loan forgiveness and $81.3 million in deposit growth over the same period. As of September 30, 2021, PPP loans outstanding amounted to $148.2 million, net of deferred SBA fees. Excluding PPP loans, we had strong loan growth of $45.8 million during the third quarter of 2021."

Executive Chairman & Founder George Duncan commented, "During the third quarter of 2021, we achieved very positive accomplishments in our branch network. We completed the Lawrence, Massachusetts branch relocation and made great progress towards our Lexington, Massachusetts relocation, which we expect to complete in late December or early January. Construction on our 27th branch, which will be located in Londonderry, New Hampshire, has begun and we anticipate opening in the second quarter of 2022."

On September 9, 2021, Enterprise Bank was recognized at the Boston Business Journal's Corporate Citizenship Summit as ranking 3rd for the highest average hours of community service and 51st among the largest corporate donors in Massachusetts. Mr. Duncan said, "I am personally very proud of this team accomplishment. Our

commitment to the communities we serve is entrenched in our culture and reflects our deep sense of purpose as a

genuine community bank."

Net Income

Net income for the three and nine months ended September 30, 2021 amounted to $9.8 million, a decrease of $494 thousand, and $31.3 million, an increase of $9.7 million, compared to the respective prior year periods. The changes in net income were primarily attributable to increases in net interest income and decreases in the provision for credit losses, partially offset by decreases in non-interest income and increases in non-interest expense. Non-interest income for the third quarter of 2021 included a $1.8 million loss from the termination of interest-rate swaps used in hedge transactions. Excluding this realized loss, non-interest income increased over the respective prior year periods.

Net Interest Income

Net interest income for the three and nine months ended September 30, 2021 amounted to $35.9 million, an increase of $2.3 million, or 7%, and $105.9 million, an increase of $9.9 million, or 10%, compared to the respective prior year periods.

•The quarter-to-date increase was due largely to increases in PPP loan income of $1.4 million and investment security income of $668 thousand and lower deposit interest expense of $1.4 million, partially offset by lower non-PPP loan income of $1.5 million.

•The year-to-date increase was due largely to an increase in PPP loan income of $10.5 million and lower deposit interest expense of $6.6 million, partially offset by a decrease in non-PPP loan income of $7.2 million and an increase in subordinated debt interest expense of $1.2 million.

•Net interest income included PPP loan income of $4.9 million and $16.5 million for the three and nine month periods of 2021, compared to $3.5 million and $6.0 million for each of the respective periods in 2020.

Net Interest Margin

Tax equivalent net interest margin ("net interest margin" or "margin") was 3.39% and 3.46% for the three months ended September 30, 2021 and 2020, respectively. Margin was 3.48% and 3.63% for the nine months ended September 30, 2021 and 2020, respectively.

Margin has been negatively impacted by large balances in lower-yielding interest-earning deposits with banks, and to a lesser extent loan pay-downs and a lower interest rate environment, partially offset by accelerated SBA fee income on PPP loan forgiveness.

For the three months ended September 30, 2021 and 2020:

•The average interest-earning deposits with banks were $675.7 million and $257.8 million.

•The average PPP loan balances, net of deferred SBA fees, were $223.6 million and $493.8 million.

•Adjusted net interest margin (non-GAAP) was 3.68% and 3.84%.

For the nine months ended September 30, 2021 and 2020:

•The average interest-earning deposits with banks were $488.2 million and $146.5 million.

•The average PPP loan balances, net of deferred SBA fees, were $361.9 million and $288.0 million.

•Adjusted net interest margin (non-GAAP) was 3.69% and 3.87%.

Provision for Credit Losses

The provision for credit losses for the three and nine months ended September 30, 2021, amounted to $28 thousand, and $747 thousand, a decrease of $1.5 million and $9.7 million, compared to the respective prior year periods.

•The current three-and-nine-month provisions resulted primarily from core loan growth (non-GAAP) and an increase in reserves for unfunded commitments, partially offset by a reduction from changes in general loan loss reserve factors and declines in reserves for individually evaluated loans.

•The provision in the prior year periods reflected increases in reserves related to the anticipated impact of the COVID-19 pandemic on the credit quality of the loan portfolio and an increase in reserves for individually evaluated loans.

Non-Interest Income

Non-interest income for the three and nine months ended September 30, 2021, amounted to $3.1 million, a decrease of $1.2 million, or 29%, and $12.1 million, a decrease of $402 thousand, or 3%, compared to the respective prior year periods.

•The decrease for the current three-month period resulted primarily from a $1.8 million loss on the early termination of $75.0 million in interest-rate swaps used in hedges.

•Excluding the interest-rate swap termination, non-interest income during the third quarter of 2021 increased $602 thousand, compared to the prior period, resulting primarily from increases in wealth management fees of $299 thousand and deposit and interchange fees of $206 thousand, partially offset by decreases in net gains on sales of loans of $152 thousand and on sales of debt securities of $127 thousand.

•Excluding the interest-rate swap termination, year-to-date non-interest income increased $1.4 million, compared to the prior year, resulting primarily from increases in wealth management fees of $763 thousand, deposit and interchange fees of $266 thousand and equity securities market value gains of $290 thousand included in other income.

Non-Interest Expense

Non-interest expense for the three and nine months ended September 30, 2021, amounted to $25.8 million, an increase of $3.0 million, or 13%, and $75.6 million, an increase of $5.8 million, or 8%, compared to the respective prior year periods.

•The increase for the current three-month period resulted primarily from increases in salaries and employee benefits of $2.2 million, occupancy and equipment of $372 thousand and technology and telecommunications of $267 thousand due primarily to the Company's long-term growth and technology initiatives.

•The increase for the current nine-month period resulted primarily from increases in salaries and employee benefits of $3.1 million, occupancy and equipment of $911 thousand, technology and telecommunications of $1.1 million, and a loss on the redemption of subordinated debt of $713 thousand included in other operating expenses, partially offset by the decrease in deposit insurance premiums of $363 thousand.

•The current three-and-nine-month results were impacted by increases of $1.3 million and $1.8 million, respectively, in the Company's variable compensation incentive plan, which are included in salary and employee benefits. Excluding this increase, non-interest expense for the three and nine-month periods increased 8% and 6% over the comparable prior year results.

Adoption of CECL

In the first quarter of 2021, the Company adopted the Financial Accounting Standards Board's guidance related to measuring credit losses, including the current expected credit losses ("CECL") methodology for estimating the allowance for credit losses ("ACL"). The CECL methodology requires earlier recognition of credit losses using a lifetime credit loss measurement approach that also requires the consideration of reasonable and supportable forecasts in the estimate.

The adoption of CECL resulted in the Company recording a net cumulative-effect adjustment, effective January 1, 2021, that decreased retained earnings by $6.5 million, net of $2.5 million in deferred income taxes. The ACL for loans increased by $6.6 million and the ACL for unfunded commitments (included in other liabilities) increased by $2.4 million.

Asset Quality

The ACL for loans amounted to $47.3 million, or 1.66% of total loans and 1.75% of total core loans (non-GAAP), at September 30, 2021, compared to $44.6 million, or 1.45% of total loans and 1.69% of total core loans (non-GAAP), at December 31, 2020. The ACL for unfunded commitments amounted to $3.0 million at September 30, 2021.

Net charge-offs for the three and nine months ended September 30, 2021 amounted to $2.1 million and $4.1 million, compared to $64 thousand and $176 thousand for the respective prior year periods. Net charge-offs for 2021 related primarily to two individually evaluated commercial loans, which were fully reserved for prior to 2021.

3

Payment deferrals due to COVID-19 remained active on 4 loans, amounting to $11.8 million, or 0.44% of total core loans (non-GAAP), at September 30, 2021, compared to 17 loans amounting to $36.0 million, or 1.36% of total core loans (non-GAAP), at June 30, 2021.

Non-performing assets amounted to $30.2 million, or 0.68% of total assets, at September 30, 2021, compared to $38.1 million, or 0.95% of total assets, at December 31, 2020, and $21.6 million, or 0.53% of total assets, at September 30, 2020.

•The Company had $2.4 million in OREO at September 30, 2021, consisting of one commercial office building reclassified to OREO in April 2021, and had no OREO at December 31, 2020 and September 30, 2020.

•The decrease in non-performing assets at September 30, 2021, compared to December 31, 2020, was due to the partial charge-off of two commercial relationships, including the note related to the OREO property discussed above, as well as principal pay-downs and credit upgrades based on improved performance, partially offset by additional downgrades.

•The increase in non-performing assets at December 31, 2020, compared to September 30, 2020, was due primarily to three commercial relationships, including the note related to the OREO property discussed above, which were placed on non-accrual in late 2020 and are in industries that have been highly impacted by the pandemic.

Balance Sheet

Total assets amounted to $4.45 billion at September 30, 2021, compared to $4.01 billion at December 31, 2020, an increase of $437.1 million, or 11%. The increase related primarily to net increases in interest-earning assets.

Total interest-earning deposits with banks amounted to $606.3 million at September 30, 2021, compared to $213.1 million at December 31, 2020. The increase resulted primarily from increases in customer deposits and PPP loan forgiveness payments received from the SBA. Excess liquidity was partially utilized to fund growth in the Company's investment security portfolio and core loans (non-GAAP) during the quarter ended September 30, 2021.

Total investments amounted to $819.2 million at September 30, 2021, compared to $583.0 million at December 31, 2020, an increase of $236.2 million, or 41%. The increase resulted primarily from purchases of $211.4 million during the current quarter.

Total loans amounted to $2.85 billion at September 30, 2021, compared to $3.07 billion at December 31, 2020, a decrease of $225.8 million, or 7%.

•As of September 30, 2021, the Company had 846 PPP loans outstanding with a principal balance of $153.6 million and deferred SBA fees of $5.3 million compared to 2,633 PPP loans outstanding with a principal balance of $453.1 million and deferred SBA fees of $10.0 million at December 31, 2020.

•During the nine-month period ended September 30, 2021, PPP forgiveness payments received from the SBA amounted to $507.3 million and round three PPP originations, which ended in May 2021, amounted to $207.8 million.

Total core loans (non-GAAP) amounted to $2.70 billion at September 30, 2021 and increased $69.1 million or 3%, compared to December 31, 2020. Core loans (non-GAAP) increased $45.8 million, or 2%, during the third quarter (7% annualized rate).

Customer deposits amounted to $3.97 billion at September 30, 2021, compared to $3.48 billion at December 31, 2020, an increase of $494.7 million, or 14%. Customer deposits increased $81.3 million, or 2%, during the third quarter of 2021.

Wealth assets under management, which are not carried as assets on the Company's consolidated balance sheets, amounted to $966.2 million at September 30, 2021, compared to $976.5 million at December 31, 2020, a decrease of $10.3 million, or 1%. The decrease resulted primarily from the departure of a large institutional relationship following the client's merger. Excluding the aforementioned client, assets under management increased 9% over the nine-month period from net new assets and increases in market values.

Capital

The Total Regulatory Capital and Tier 1 Capital to risk weighted asset ratios for the Company were 14.15% and 10.93%, respectively, at September 30, 2021. The Company's September 30, 2021 capital ratios have been impacted by the following since September 30, 2020:

•The redemption of $15.0 million of fixed-to-floating rate subordinated notes in the first quarter of 2021, which were classified as Tier 2 capital. Tier 1 capital was not impacted by the redemption.

•The adoption of CECL in the first quarter of 2021,which resulted in a $6.5 million deduction from capital.

•Additionally, the Total Regulatory Capital and Tier 1 Capital ratios were positively impacted by growth in lower risk-weighted assets and retained earnings during the period.

Non-GAAP Measures

Throughout this press release we have noted certain balances, ratios or other measures of the Company's performance which exclude the impact of PPP loans, which we expect to be short-term in nature. We refer to any balance, ratio or measure that excludes PPP loans as "core." In addition, we refer to any balance, ratio or measure that excludes PPP loans and interest-earning deposits with banks as "adjusted." The core and adjusted balances, ratios and measures were derived in order to provide more meaningful comparisons to prior periods as: (1) PPP loans outstanding have been originated within the last 18 months and the majority are expected to pay off during the next several quarters; and (2) growth in customer deposits and PPP loan pay-downs have led to temporarily high liquidity, carried as lower-yielding interest-earning deposits with banks, compared to prior periods. The tables beginning on page 10 provide a reconciliation of the non-GAAP measures to the information presented under U.S. generally accepted accounting principles ("GAAP").

NON-GAAP MEASURES

Non-GAAP financial measures are not a substitute for GAAP measures; they should be read and used in conjunction with the Company's GAAP financial information. In addition, the non-GAAP financial measures we present may differ from non-GAAP financial measures used by our peers or other companies.
