Enterprise Bancorp, Inc. Announces Fourth Quarter Financial Results

LOWELL, MA, January 26, 2023 (GLOBE NEWSWIRE) - Enterprise Bancorp, Inc. (NASDAQ: EBTC), parent of Enterprise Bank, announced net income for the three months ended December 31, 2022, of $12.3 million, or $1.01 per diluted common share, compared to $10.8 million, or $0.90 per diluted common share, for the three months ended December 31, 2021. Net income for the year ended December 31, 2022, amounted to $42.7 million, or $3.52 per diluted common share, compared to $42.2 million, or $3.50 per diluted common share, for the year ended December 31, 2021.

Chief Executive Officer Jack Clancy commented, "Net income for the quarter increased 13% over the prior year period led by strong loan growth and higher interest rates. In the fourth quarter, loans increased by 2% (9% annualized) and tax-equivalent net interest margin (non-GAAP) increased to 3.81%, which was the highest level since the first quarter of 2020."

Mr. Clancy continued, "Core loan growth (non-GAAP), which excludes PPP loans, was 12% for the full year and was funded primarily from our overnight liquidity position. Total customer deposits increased 1% over the prior year. Credit quality and loan reserves remain solid. Non-performing loans amounted to 0.19% of total loans and the allowance for credit losses to total loans was 1.66% as of December 31, 2022. Additionally, we had $4.3 million in reserves for unfunded commitments."

Executive Chairman & Founder George Duncan commented, "2022 was a very successful year with net income of $42.7 million and diluted earnings per share of $3.52 for the year ended December 31, 2022, and on January 17, 2023, the Company declared a quarterly dividend of $0.23 per share, an increase of 12% over the prior year quarter."

Mr. Duncan continued, "During 2022, we opened a branch in Londonderry, New Hampshire, which was our third branch opening since the pandemic began in 2020, following successful openings in Lexington, Massachusetts in 2020 and North Andover, Massachusetts in 2021. Our branch growth strategy is to enter strong demographic markets and invest significantly in business development and community initiatives. Our focus on community involvement, outstanding and responsive service, and a strong digital platform provides the foundation to deliver valued products and services including commercial lending, residential mortgages, cash management, and wealth management. Our approach has been highly successful and we are experiencing excellent market penetration in these new locations."

Mr. Duncan also highlighted, "In November 2022, we were recognized by the Boston Globe for our deep commitment to our team members. Enterprise Bank ranked 7<sup>th</sup> on the Boston Globe's Top Places to Work ("TPTW") list. We were the highest rated bank in our category of large sized companies in Massachusetts and our inclusion in 2022 was our eleventh consecutive year on the TPTW list. I want to personally thank and commend our entire dedicated team for their continual efforts in fostering an employee-centric culture whose foundation is based on respect, trust, care, personal accountability and excellence."

*<u>Net Income</u>*

Net income for the three months ended December 31, 2022, amounted to $12.3 million, an increase of $1.5 million, or 13%, compared to the three months ended December 31, 2021.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;*•* The increase in net income was due primarily to an increase in net interest income of $6.5 million, partially offset by increases in the provision for credit losses of $838 thousand and non-interest expense of $1.6 million and a decrease in non-interest income of $1.8 million.

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;*•* The decrease in non-interest income for the three months ended December 31, 2022 was impacted by three non-core operating transactions further discussed under the heading "Non-Interest Income," below.

*<u>Net Interest Income</u>*

Net interest income for the three months ended December 31, 2022, amounted to $42.2 million, an increase of $6.5 million, or 18%, compared to the three months ended December 31, 2021.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The increase in net interest income was due largely to increases in loan income, excluding Paycheck Protection Program ("PPP") income (non-GAAP), of $8.5 million and other interest-earning asset income of $3.2 million, partially offset by a decrease in PPP income of $3.2 million and an increase in deposit interest expense of $2.4 million.

*<u>Net Interest Margin</u>*

Tax-equivalent net interest margin ("net interest margin") (non-GAAP) was 3.81% for the three months ended December 31, 2022, compared to 3.61% and 3.34% for the three months ended September 30, 2022 and December 31, 2021, respectively.

Net interest margin has been favorably impacted by increases in market interest rates and the prime lending rate over the comparable periods. In particular, interest-earning deposits with banks have been impacted most favorably, as noted below.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Average interest-earning deposits with banks amounted to $358.2 million, a decrease of $173.3 million, or 33%, while the yield increased 354 basis points. The decrease in average interest-earning deposits with banks resulted primarily from funding growth in the loan portfolio and the increase in yield reflected a significant change in market interest rates during 2022.

Other items impacting net interest margin for the three months ended December 31, 2022, compared to the prior year period, included:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Average investment securities increased $81.6 million, or 9%, while the tax-equivalent yield remained unchanged.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Average loans increased $245.3 million, or 9%, and the tax-equivalent yield increased 32 basis points.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;*◦* Average core loans (non-GAAP) increased $347.1 million, or 13%, and the yield increased 62 basis points. Core loan yields (non-GAAP) have benefited primarily from increases in the prime lending rate of 425 basis points between March and December of 2022.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;*◦* Average PPP loans outstanding decreased $101.7 million, or 98%, due to the continued forgiveness of PPP loans by the Small Business Administration (the "SBA") during the period. PPP income amounted to $24 thousand for the three months ended December 31, 2022, compared to $3.2 million for the three months ended December 31, 2021.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Average total deposits increased $128.8 million, or 3%, and the yield increased 23 basis points as a result of higher market rates due to competition within the market.

*<u>Provision for Credit Losses</u>*

The provision for credit losses for the three months ended December 31, 2022, amounted to $1.9 million, compared to $1.0 million for the three months ended December 31, 2021.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;*•* The provision for the three months ended December 31, 2022, consisted of $1.6 million for loans outstanding and $266 thousand for reserves on unfunded commitments (included in other liabilities).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The majority of the provision for credit losses during the fourth quarter of 2022 related to growth in the Company's loan portfolio and in off-balance sheet commitments.

------

*<u>Non-Interest Income</u>*

Non-interest income for the three months ended December 31, 2022, amounted to $4.2 million, a decrease of $1.8 million, or 30%, compared to the three months ended December 31, 2021 and was impacted by the following three non-core operating items:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• On October 5, 2022, the Company ended its revenue sharing relationship with an insurance agency and sold the rights to the future cash flows on these insurance policies to the agency. The transaction resulted in a one-time gain on sale of insurance commissions of $2.0 million and the Company has no other insurance agency relationships. Prior to the sale, the Company had referred clients, assisted with servicing and shared the resulting revenue.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• In the fourth quarter, the Company realized net losses on sales of debt securities of $3.0 million after executing a bond restructure in which it sold lower-yielding debt securities with an amortized cost of $39.9 million.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Non-interest income for the prior year quarter was impacted by a gain on the sale of other real estate owned ("OREO") of $1.1 million.

Excluding these three non-core operating items, non-interest income increased $359 thousand, or 7%, resulting primarily from increases in deposit and interchange fees of $448 thousand, partially offset by a decrease in wealth management fees of $201 thousand.

*<u>Non-Interest Expense</u>*

Non-interest expense for the three months ended December 31, 2022, amounted to $28.2 million, an increase of $1.6 million, or 6%, compared to the three months ended December 31, 2021.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The increase in non-interest expense over the prior year period resulted primarily from increases in salaries and employee benefits of $1.4 million, audit, legal and other professional fees of $226 thousand and advertising and public relation expense of $250 thousand.

*<u>Credit Quality</u>*

*The allowance for credit losses ("ACL") for loans* amounted to $52.6 million, or 1.66% of total loans, at December 31, 2022, compared to $47.7 million, or 1.63% of total loans, at December 31, 2021. The reserve for unfunded commitments (included in other liabilities) amounted to $4.3 million at December 31, 2022, compared to $3.7 million at December 31, 2021. The Company's reserves were impacted by growth and worsening forecasted economic conditions, partially offset by strong credit quality.

*Net charge-offs* for the three months ended December 31, 2022, amounted to $166 thousand, compared to net recoveries of $108 thousand for the three months ended December 31, 2021.

*Non-performing loans* amounted to $6.1 million, or 0.19% of total loans, at December 31, 2022, compared to $26.5 million, or 0.91% of total loans, at December 31, 2021. The decrease in non-performing loans was due primarily to two commercial relationships, amounting to $17.9 million, which were upgraded and restored to accrual status during the second quarter of 2022, due to improved financial strength and consistent payment history. At December 31, 2022 and December 31, 2021, the Company had no OREO.

*<u>Balance Sheet</u>*

*Total assets* amounted to $4.44 billion at December 31, 2022, compared to $4.45 billion at December 31, 2021, a decrease of $9.5 million.

*Total interest-earning deposits with banks* amounted to $230.7 million at December 31, 2022, compared to $403.0 million at December 31, 2021, a decrease of $172.3 million, or 43%. The decrease in interest-earning deposits with banks was primarily from loan growth.

------

*Total investm*e*nt securities at fair value* amounted to $820.4 million at December 31, 2022, compared to $958.2 million at December 31, 2021, a decrease of $137.8 million, or 14%. The change resulted primarily from a decline in the fair value of the Company's debt securities portfolio of $130.0 million during the period. Management has concluded that the unrealized losses resulted from significant increases in market interest rates during 2022 and that no allowance for credit losses was considered necessary as of December 31, 2022.

*Total loans* amounted to $3.18 billion at December 31, 2022, compared to $2.92 billion at December 31, 2021, an increase of $259.8 million, or 9%.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;*• Core loans (non-GAAP)* increased $329.1 million, or 12%, over the respective periods. Included in the loan growth for the period was $75.7 million in retained residential mortgages.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;*•* At December 31, 2022, the Company had $2.2 million in PPP loans outstanding, compared to $71.5 million at December 31, 2021. Loans that were originated under the PPP and remained outstanding at December 31, 2022 are considered to be core loans (non-GAAP), as management does not expect the majority of the remaining balances to be forgiven by the SBA.

*Customer deposits* amounted to $4.04 billion at December 31, 2022, compared to $3.98 billion at December 31, 2021, an increase of $55.6 million, or 1%.

*<u>Shareholders' Equity & Regulatory Capital</u>*

*Total shareholders' equity* amounted to $282.3 million at December 31, 2022, compared to $346.9 million at December 31, 2021, a decrease of $64.6 million, or 19%. The change was attributable primarily to a decrease in accumulated other comprehensive income ("AOCI") of $100.9 million since December 31, 2021, partially offset by an increase in retained earnings of $32.8 million over the same period. The change in AOCI resulted from a decrease in the fair value of debt securities, which is attributed to the significant increase in market interest rates during the year ended December 31, 2022. The Company classifies all debt securities as available-for-sale and anticipates they will mature or be called at par value.

The Company's reported book value per common share and return on average shareholders' equity ratios were impacted by the change in AOCI as follows:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;*• Book value per common share* was $23.26 at December 31, 2022, compared to $28.82 at December 31, 2021, a decrease of 19%. Excluding AOCI (non-GAAP), book value per common share was $31.19 at December 31, 2022, compared to $28.43 at December 31, 2021, an increase of 10%.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;*• Return on average shareholders' equity* was 18.08% and 12.56% for the quarters ended December 31, 2022, and December 31, 2021, respectively. Return on average shareholders' equity, excluding AOCI (non-GAAP), was 13.03% and 12.69% for the quarters ended December 31, 2022, and December 31, 2021, respectively.

*Total Capital and Tier 1 Capital to risk weighted assets,* of which AOCI is not a component, amounted to 13.49% and 10.56%, respectively, at December 31, 2022 compared to 13.73% and 10.62%, respectively, at December 31, 2021. The decrease in capital ratios was attributed mostly to loan growth.

*<u>Wealth Management</u>*

*Wealth assets under management and wealth assets under administration*, which are not carried as assets on the Company's consolidated balance sheets, amounted to $891.5 million and $198.6 million, respectively, at December 31, 2022, representing decreases of $150.0 million, or 14%, and $59.3 million, or 23%, respectively, compared to December 31, 2021. The decreases in wealth assets under management and wealth assets under administration were attributable primarily to declines in market values during the year ended December 31, 2022.

*<u>Non-GAAP Measures</u>*

Throughout this press release, certain measures have been adjusted to provide what management believes are more meaningful comparisons between periods. The items principally impacted and reported as non-GAAP were loans (PPP loans), shareholders' equity (AOCI), and any related measures presented. We refer to any prior period measure that excludes PPP loans as "core". The remaining PPP loans outstanding at December 31, 2022 are included in core

------

loans (non-GAAP), as the majority of the remaining balances are no longer expected to be forgiven by the SBA. The activity which resulted in the Company's use of non-GAAP measures consisted of: (1) the Company's origination of over $715 million in short-term PPP loans between April 2020 and May 2021; (2) forgiveness of PPP loans by the SBA which began in November 2020 and continued through the current period, and approximately 99.7% of the principal balance of PPP loans originated by the Company has been forgiven by the SBA through December 31, 2022; and (3) the significant increase in market interest rates during 2022 has resulted in unrealized losses in the Company's available-for-sale debt securities portfolio at December 31, 2022 of $124.1 million and an accumulated other comprehensive loss, included in shareholder's equity, of $96.2 million. The tables beginning on page 12 of this press release provide a reconciliation of the non-GAAP measures to the information presented under U.S. generally accepted accounting principles ("GAAP").
