Arrow Reports 3rd Quarter Net Income of $9.0 Million, or $0.53 per Share

GLENS FALLS, N.Y. (October 31, 2024) - Arrow Financial Corporation (NasdaqGS® - AROW) ("Arrow" or "the Company") announced financial results for the three-month period ended September 30, 2024. Net income for the third quarter of 2024 was $9.0 million and fully diluted earnings per share ("EPS") was $0.53, versus $7.7 million and EPS of $0.46 for the same period in 2023.

This Earnings Release and related commentary should be read in conjunction with the Company's October 31, 2024 Form 8-K and related Third Quarter 2024 Investor Presentation, which can also be found on Arrow's website: arrowfinancial.com/documents/investor-presentations.

Arrow President and CEO David S. DeMarco:

"We delivered a solid third quarter with strong net interest margin expansion, improved core profitability, increased return on average assets and continued strong credit metrics. Stabilizing funding costs, increasing asset yields, and continued expense discipline have positioned us for increased core operating leverage for the upcoming quarters. Our incredible teamwork was recently recognized by being named to the prestigious Piper Sandler Sm-All Stars: Class of 2024, a list of 30 top-performing small-cap banks and thrifts in the country.

Among our third-quarter accomplishments, we completed two small acquisitions. We expanded our insurance business with the strategic acquisition of the assets of A&B Agency, Inc. and acquired a branch in Whitehall, New York. Our team continues to prepare for the unification of our banking subsidiaries, Glens Falls National Bank and Trust Company and Saratoga National Bank and Trust Company, into a single entity renamed Arrow Bank National Association, or Arrow Bank, slated for December 31, 2024. Starting in early November, our customers will gain surcharge-free access to the Allpoint ATM Network of more than 55,000 locations. As we continue to strengthen our market position, we also rewarded our shareholders with an increase to the fourth-quarter cash dividend, which we announced in early October."

Income Statement

•Net Income: Net income for the third quarter of 2024 was $9.0 million, increasing from $8.6 million in the second quarter of 2024 and $7.7 million in the third quarter of 2023.

◦Compared to the prior quarter, net income benefited from an increase of $1.3 million in net interest income, partially offset by an increase in non-interest expense of $0.8 million.

◦Compared to the third quarter of 2023, net income growth was driven by an increase in net interest income of $3.1 million, partially offset by an increase in non-interest expense of $0.6 million.

•Net Interest Income: Net interest income for the third quarter of 2024 was $28.4 million, increasing 4.7% from $27.2 million for the second quarter of 2024 and increasing 12.2% from $25.4 million in the third quarter of 2023.

◦Total interest and dividend income was $49.4 million for the third quarter of 2024, an increase from $48.0 million in the second quarter of 2024 and from $42.1 million for the third quarter of 2023. These increases were primarily driven by loan growth and higher loan yields. Interest expense for the third quarter of 2024 was $21.0 million, an increase from $20.8 million for the second quarter of 2024 and from $16.8 million for the third quarter of 2023. The increase from the prior year was driven primarily by higher deposit rates and changes in deposit composition.

•Net Interest Margin: Net interest margin, on an FTE basis, for the third quarter of 2024 was 2.79% compared to 2.69% for the second quarter of 2024 and 2.55% for the third quarter of 2023. The increase in net interest margin compared to the second quarter in 2024 was primarily the result of continued yield expansion on earning assets combined with the moderating cost of interest-bearing liabilities. As compared to the third quarter of 2023, the increase in net interest margin was primarily the result of yield on average earning assets increasing at a faster pace than costs of interest-bearing liabilities. Net interest margin is affected by deposits continuing to migrate to higher costing products, such as money market savings and time deposits.

•Provision for Credit Losses: For the third quarter of 2024, the provision for credit losses was $0.9 million compared to $0.8 million in the second quarter of 2024 and $0.4 million in the third quarter of 2023. The key drivers for the provision for credit losses in the third quarter of 2024 were replenishment of the allowance for charge-offs, growth in loan balances and changes to the economic forecast factors embedded in the credit loss allowance model.

•Non-Interest Income: Non-interest income for the three months ended September 30, 2024, was $8.1 million, an increase from $7.9 million in the second quarter of 2024 and consistent with the third quarter of 2023. The increases from the prior periods are primarily the result of the resumption of loan sales from current loan originations, higher wealth management fees resulting from improved market valuations of assets under management and increased insurance commissions resulting from the A&B asset acquisition. The third quarter of 2023 included one-time proceeds from bank-owned life insurance in other income.

•Non-Interest Expense: Non-interest expense for the third quarter of 2024 was $24.1 million, an increase from $23.3 million in the second quarter of 2024 and an increase from $23.5 million for the third quarter of 2023. The increase from the prior quarter was primarily attributable to several one-time non-core expenses related to the Whitehall and A&B asset acquisitions.

•Provision for Income Taxes: The provision for income taxes and effective tax rate were $2.6 million and 22.2%, for the third quarter of 2024, $2.3 million and 21.2%, for the second quarter of 2024 and $1.8 million and 19.1%, for the third quarter of 2023. The increase in the effective tax rate from the second quarter of 2024 was primarily attributable to a decrease in the amount of tax advantaged earning assets as a percentage of total earning assets, while the increase in the effective tax rate from the third quarter of 2023 was primarily due to a change in pre-tax income combined with a decrease in the amount of tax advantaged earning assets as a percentage of total earning assets.

Balance Sheet

•Total Assets: Total assets were $4.4 billion at September 30, 2024, an increase of $167.0 million, or 3.9%, as compared to June 30, 2024 and an increase of $138.5 million, or 3.2%, as compared to September 30, 2023. For the third quarter of 2024, overall growth in the balance sheet was attributable to changes in cash balances, primarily seasonal municipal and corporate deposits, as well as growth in the loan portfolio.

•Investments: Total investments were $549.8 million as of September 30, 2024, a decrease of $6.6 million, or 1.2%, compared to June 30, 2024 and a decrease of $117.0 million, or 17.6%, compared to September 30, 2023. The decrease from June 30, 2024 was driven primarily by paydowns and maturities. The decrease from September 30, 2023 was also driven by paydowns and maturities as well as the fourth quarter 2023 repositioning of the investment portfolio, which reduced the portfolio by approximately $25 million at the time of the transaction. There were no credit quality issues related to the investment portfolio.

•Loans3: Total loans were $3.3 billion as of September 30, 2024. Loan growth for the third quarter of 2024 was $24.2 million, and $201.2 million since September 30, 2023. Loan growth was spread across all loan products. Please see the loan detail included in the Consolidated Financial Information table on page 13.

•Allowance for Credit Losses: The allowance for credit losses was $31.3 million as of September 30, 2024, which represented 0.94% of loans outstanding, as compared to $31.0 million, or 0.94%, at June 30, 2024, and $31.1 million, or 0.99%, at September 30, 2023. Net charge-offs, expressed as an annualized percentage of average loans outstanding, were 0.08% for the three-month period ended September 30, 2024, as compared to 0.16%4 for the three-month period ended June 30, 2024 and 0.05% for the three-month period ended September 30, 2023. Non

performing assets were $22.3 million as of September 30, 2024, representing 0.51% of period-end assets, compared to 0.50% at June 30, 2024 and 0.16% at September 30, 2023.

•Deposits: At September 30, 2024, deposit balances were $3.8 billion, an increase of $153.8 million from June 30, 2024 and an increase of $171.0 million from September 30, 2023. The increase from the second quarter was primarily attributable to the seasonality of municipal deposits. The increase from September 30, 2023 was partially attributable to $175 million of brokered CDs, primarily used to reduce borrowings and fund continued loan growth. Please refer to page 7 for further details related to deposits.

•Capital: Total stockholders' equity was $393.3 million at September 30, 2024, an increase of $10.3 million, or 2.7%, from June 30, 2024 and an increase of $33.3 million, or 9.2%, from the September 30, 2023 level of $360.0 million. The increase from the second quarter was primarily attributable to net income of $9.0 million, other comprehensive income of $5.7 million offset by dividends of $4.5 million. The increase in stockholders' equity from September 30, 2023 was primarily attributable to income for the period of $32.9 million, other comprehensive income of $26.6 million and various capital items of $1.1 million offset by dividends of $18.1 million and stock repurchases of $9.2 million. Arrow's regulatory capital ratios remained strong. As of September 30, 2024, Arrow's Common Equity Tier 1 Capital Ratio was 12.77% and Total Risk-Based Capital Ratio was 14.46%. The capital ratios of Arrow's subsidiary banks, Glens Falls National Bank and Trust Company and Saratoga National Bank and Trust Company, continued to exceed the "well capitalized" regulatory standards.

1.	Non-GAAP Financial Measure Reconciliation: Tangible Book Value, Tangible Equity, and Return on Tangible Equity exclude goodwill and other intangible assets, net from total equity. These are non-GAAP financial measures which Arrow believes provide investors with information that is useful in understanding its financial performance.

2.	Non-GAAP Financial Measure Reconciliation: Net Interest Margin is the ratio of annualized tax-equivalent net interest income to average earning assets. This is also a non-GAAP financial measure which Arrow believes provides investors with information that is useful in understanding its financial performance.

3.	Non-GAAP Financial Measure Reconciliation: Financial Institutions often use the "efficiency ratio", a non-GAAP ratio, as a measure of expense control. Arrow believes the efficiency ratio provides investors with information that is useful in understanding its financial performance. Arrow defines efficiency ratio as the ratio of non-interest expense to net gross income (which equals tax-equivalent net interest income plus non-interest income, as adjusted).
4.	For the current quarter, all of the regulatory capital ratios as well as the Total Risk-Weighted Assets are calculated in accordance with bank regulatory capital rules. The September 30, 2024 CET1 ratio listed in the tables (i.e., 12.77%) exceeds the sum of the required minimum CET1 ratio plus the fully phased-in Capital Conservation Buffer (i.e., 7.00%).
