**FINANCIAL INSTITUTIONS, INC. ANNOUNCES SECOND QUARTER 2025 RESULTS**

**WARSAW, N.Y., July 24, 2025** – Financial Institutions, Inc. (NASDAQ: FISI) (the "Company," "we" or "us"), parent company of Five Star Bank (the "Bank") and Courier Capital, LLC ("Courier Capital"), today reported financial and operational results for the second quarter ended June 30, 2025.

The Company reported net income of $17.5 million in the second quarter of 2025, compared to $16.9 million in the first quarter of 2025 and $25.6 million in the second quarter of 2024. After preferred dividends, net income available to common shareholders was $17.2 million, or $0.85 per diluted share, in the second quarter of 2025, compared to $16.5 million, or $0.81 per diluted share, in the first quarter of 2025, and $25.3 million, or $1.62 per diluted share, in the second quarter of 2024. The Company recorded a provision for credit losses of $2.6 million in the current quarter, compared to $2.9 million in the linked quarter and $2.0 million in the prior year quarter.

**Second Quarter 2025 Highlights:**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Net interest margin of 3.49% for second quarter of 2025 was up 14 and 62 basis points from the linked and year-ago quarters, respectively, while net interest income of $49.1 million for second quarter of 2025 increased $2.3 million, or 4.8%, from the first quarter of 2025 and $7.9 million, or 19.2%, from the second quarter of 2024.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Noninterest income was $10.6 million in the second quarter of 2025, compared to $10.4 million in the linked quarter and $24.0 million in the year-ago quarter, when results benefited from a $13.5 million pre-tax gain associated with the sale of the Company's insurance business.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Total loans were $4.54 billion at June 30, 2025, reflecting a decrease of $17.3 million, or 0.4%, from March 31, 2025, driven by a decrease in our consumer indirect lending portfolio as pay-downs exceeded originations, and an increase of $74.5 million, or 1.7%, from one year prior.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Total deposits were $5.16 billion at June 30, 2025, down $216.9 million, or 4.0%, from March 31, 2025, driven by both seasonal public deposit outflows and the previously announced wind-down of the Company's Banking-as-a-Service, or BaaS, offering, and relatively flat compared to one year prior.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Nonperforming assets to total assets were 0.53% at June 30, 2025, down from 0.63% at the linked quarter-end and up from 0.41% one year prior.

"Second quarter 2025 financial results were highlighted by continued margin expansion, increased net interest income and durable noninterest revenues, which allowed us to deliver 4% growth in net income available to common shareholders from the linked first quarter," said President and Chief Executive Officer Martin K. Birmingham. "Profitability continues to be a paramount focus, and we were pleased to maintain an efficiency ratio below 60% and report solid annualized return on average assets and return on average equity of 1.13% and 11.78%, respectively, for the most recent quarter.

"Deposit balances reflect typical seasonality within our public deposit portfolio and total loans were relatively flat with the end of the first quarter, as commercial business lending growth was more than offset by a reduction in consumer indirect balances. Given our strong first quarter loan production and existing pipelines, we continue to expect low single-digit full year loan growth that aligns with our credit-disciplined philosophy."

Chief Financial Officer and Treasurer W. Jack Plants II added, "Our results continue to benefit from our team's focus on prudent balance sheet stewardship through redeployment of cash flows into higher yielding assets, active investment portfolio management and our ability to effectively reprice deposits, supporting a six basis point reduction in our overall cost of funds. Expenses in the second quarter were somewhat elevated, in part reflecting timing of certain expenses and some higher costs that we expect to be nonrecurring, and we will remain intently focused on expense management through the coming quarters to support positive operating leverage in 2025."

**Net Interest Income and Net Interest Margin**

Net interest income was $49.1 million for the second quarter of 2025, an increase of $2.3 million from the first quarter of 2025, and an increase of $7.9 million from the second quarter of 2024.

------

Average interest-earning assets for the current quarter of $5.65 billion were flat with the first quarter of 2025, as a $46.9 million increase in average loans was offset by a $32.7 million decrease in the average balance of Federal Reserve interest-earning cash and a $14.0 million decrease in the average balance of investment securities. Average interest-earning assets decreased $114.5 million from the second quarter of 2024, as a $123.2 million decrease in the average balance of investment securities and a $95.1 million decrease in the average balance of Federal Reserve interest-earning cash were partially offset by a $103.8 million increase in average loans.

Average interest-bearing liabilities for the current quarter were $4.52 billion, reflecting an increase of $11.6 million from the linked quarter and a decrease of $29.8 million from the year-ago quarter. The increase from the first quarter of 2025 was primarily due to a $66.4 million increase in average time deposits that was partially offset by a $23.1 million decrease in average savings and money market deposits, a $14.2 million decrease in average interest-bearing demand deposits, a $9.1 million decrease in average short-term borrowings, and an $8.4 million decrease in average long-term borrowings. The year-over-year decrease was due to an $83.4 million decrease in average savings and money market deposits, a $54.0 million decrease in average short-term borrowings, a $10.0 million decrease in average interest-bearing demand deposits, and an $8.2 million decrease in average long-term borrowings, partially offset by a $125.7 million increase in average time deposits. The continued outflow of BaaS-related deposits, following the Company's September 2024 announcement that it would wind-down its BaaS platform, was the primary driver of the reduction in average savings and money market deposits from the linked and year-ago periods.

Net interest margin was 3.49% in the current quarter as compared to 3.35% in the first quarter of 2025, and 2.87% in the second quarter of 2024. Expansion from the linked quarter was due to increases in the average yields of both investment securities and loans, as well as lower average cost of interest-bearing liabilities, reflecting repricing of non-public and reciprocal deposits. Year-over-year margin expansion was driven by an increase in the average yield on investment securities, following the previously disclosed restructuring of the available-for-sale securities portfolio in December 2024, which supported an increase in the average yield on interest-earning assets.

**Noninterest Income** 

The Company reported noninterest income of $10.6 million for the second quarter of 2025, compared to $10.4 million in the first quarter of 2025 and $24.0 million in the second quarter of 2024.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•The Company's sale of its former insurance subsidiary generated a net gain of $13.5 million in the second quarter of 2024.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Investment advisory income of $2.9 million was $148 thousand higher than the first quarter of 2025 and up $106 thousand from the second quarter of 2024.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Income from company-owned life insurance ("COLI") of $3.0 million was $188 thousand higher than the first quarter of 2025 and $1.6 million higher than the second quarter of 2024, due to the previously disclosed restructuring of a portion of the Company's COLI portfolio into higher-yielding separate account policies in January 2025.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Income from investments in limited partnerships of $307 thousand was $108 thousand lower than the first quarter of 2025 and $496 thousand lower than the second quarter of 2024. The Company has made several investments in limited partnerships, primarily small business investment companies, and accounts for these investments under the equity method. Income from these investments fluctuates based on the maturity and performance of the underlying investments.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Other noninterest income of $1.3 million was $292 thousand lower than the linked quarter and $227 thousand lower than the year-ago quarter.

**Noninterest Expense**

Noninterest expense was $35.7 million in the second quarter of 2025, compared to $33.7 million in the first quarter of 2025, and $33.0 million in the second quarter of 2024.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Salaries and employee benefits expense of $18.1 million was $1.2 million higher than the first quarter of 2025 and $2.3 million higher than the second quarter of 2024, reflecting an increase in health insurance benefits due to higher medical claims than in the linked quarter, while the increase from the prior year quarter was primarily due to annual merit increases.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Occupancy and equipment expense of $4.0 million reflects increases of $392 thousand and $534 thousand from the linked and year-ago quarters, respectively. The linked quarter increase was due in part to timing given a change in facilities maintenance service vendors, as well as costs associated with an ongoing ATM conversion, while the year-over-year variance was due in part to the ATM conversion and upgrade project.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Professional services expenses of $1.5 million were $240 thousand lower than the first quarter of 2025 and $343 thousand lower than the second quarter of 2024. The linked quarter variance was primarily due to the timing of

------

audit related expenses, while the year-over-year variance was primarily attributable to legal expenses incurred in the second quarter of 2024 related to the Company's previously disclosed deposit-related fraud event.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Computer and data processing expense of $5.9 million was $392 thousand higher than the first quarter of 2025 and $537 thousand higher than the second quarter of 2024. Both the linked quarter and year-over-year increases were driven by the timing of expenses for in-process technology enhancement and upgrade initiatives.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•The Company recorded deposit-related charged-off items of $233 thousand for the current quarter, compared to charged-off recoveries of $294 thousand in the first quarter of 2025 and charged-off items of $398 thousand in the second quarter of 2024, with the linked quarter variance primarily driven by insurance proceeds received in the first quarter of 2025 related to a past commercial deposit charged-off item.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Other expense of $3.6 million was down $179 thousand from the linked quarter and down $381 thousand from the year-ago quarter, with the year-over-year variance primarily due to higher interest rate swap collateral charges in the second quarter of 2024.

**Income Taxes**

Income tax expense was $4.0 million for the second quarter of 2025, compared to $3.7 million in the first quarter of 2025 and $4.5 million in the second quarter of 2024. The Company also recognized federal and state tax benefits related to tax credit investments placed in service and/or amortized during the second quarter of 2025, first quarter of 2025, and second quarter of 2024, resulting in income tax expense reductions of $1.1 million, $1.1 million, and $1.3 million, respectively.

The effective tax rate was 18.4% for the second quarter of 2025, 18.2% for the first quarter of 2025, and 15.0% for the second quarter of 2024. The effective tax rate fluctuates on a quarterly basis primarily due to the level of pre-tax earnings and may differ from statutory rates because of interest income from tax-exempt securities, earnings on COLI, the tax impact of the COLI repositioning, and the impact of tax credit investments.

**Balance Sheet and Capital Management**

Total assets were $6.14 billion at June 30, 2025, down $196.7 million from March 31, 2025, and flat with June 30, 2024.

Investment securities were $1.01 billion at June 30, 2025, down $31.8 million from March 31, 2025, and flat with June 30, 2024.

Total loans were $4.54 billion at June 30, 2025, a decrease of $17.3 million, or 0.4%, from March 31, 2025, and an increase of $74.5 million, or 1.7%, from June 30, 2024.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Commercial business loans totaled $726.2 million, up $17.1 million, or 2.4%, from March 31, 2025, and up $12.3 million, or 1.7%, from June 30, 2024.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Commercial mortgage loans totaled $2.22 billion, a decline of $13.1 million, or 0.6%, from March 31, 2025, and an increase of $129.3 million, or 6.2%, from June 30, 2024.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Residential real estate loans totaled $647.2 million, up $3.2 million, or 0.5%, from March 31, 2025, and down $470 thousand, or 0.1%, from June 30, 2024.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Consumer indirect loans totaled $833.5 million, down $19.7 million, or 2.3%, from March 31, 2025, and down $61.1 million, or 6.8%, from June 30, 2024.

Total deposits were $5.16 billion at June 30, 2025, down $216.9 million, or 4.0%, from March 31, 2025, and up $22.7 million, or 0.4%, from June 30, 2024. The decrease from March 31, 2025 was primarily due to seasonally lower public deposit balances in addition to the outflow of BaaS-related deposits. The modest increase from June 30, 2024 reflected a higher level of brokered deposits, which were utilized to offset the anticipated reduction in BaaS-related deposits, as well as lower reciprocal deposit balances. The Company had approximately $7 million in BaaS-related deposits at June 30, 2025, compared to approximately $55 million at March 31, 2025 and approximately $108 million at June 30, 2024. Public deposit balances represented 21% of total deposits at June 30, 2025, 24% at March 31, 2025, and 20% at June 30, 2024.

Short-term borrowings were $101.0 million at June 30, 2025, compared to $55.0 million at March 31, 2025, and $202.0 million at June 30, 2024. Short-term borrowings and brokered deposits have historically been utilized to manage the seasonality of public deposits.

Shareholders' equity was $601.7 million at June 30, 2025, compared to $589.9 million at March 31, 2025, and $467.7 million at June 30, 2024. The linked quarter period-end increase was due to net income, net of dividends, retained, while the year-over-year period end increase was primarily driven by additional paid-in-capital resulting from the common stock capital raise executed in the fourth quarter of 2024 and a decrease in accumulated other comprehensive loss between period ends following the investment securities restructuring in the fourth quarter of 2024.

Common book value per share was $29.03 at June 30, 2025, an increase of $0.55, or 1.9%, from $28.48 at March 31, 2025, and a decrease of $0.08, or 0.3%, from $29.11 at June 30, 2024. Tangible common book value per share<sup>(1)</sup> was $26.02 at

------

June 30, 2025, an increase of $0.56, or 2.2%, from $25.46 at March 31, 2025, and an increase of $0.85, or 3.4%, from $25.17 at June 30, 2024. The common equity to assets ratio was 9.51% at June 30, 2025, compared to 9.03% at March 31, 2025, and 7.34% at June 30, 2024. Tangible common equity to tangible assets<sup>(1)</sup>, or the TCE ratio, was 8.61%, 8.15% and 6.41% at June 30, 2025, March 31, 2025, and June 30, 2024, respectively. The year-over-year increases in both ratios were attributable to the additional capital raised in the fourth quarter of 2024 and the decrease in accumulated other comprehensive loss as a result of the investment securities restructuring in the fourth quarter of 2024.

During the second quarter of 2025, the Company declared a common stock dividend of $0.31 per common share, consistent with the linked quarter and reflecting an increase of $0.01, or 3.3%, over the year-ago quarter. The dividend returned more than 36% of second quarter net income to common shareholders.

The Company's regulatory capital ratios at June 30, 2025 continued to exceed all regulatory capital requirements to be considered well capitalized.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Leverage Ratio was 9.45% compared to 9.24% and 8.61% at March 31, 2025, and June 30, 2024, respectively.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Common Equity Tier 1 Capital Ratio was 10.84% compared to 10.38% and 10.03% at March 31, 2025, and June 30, 2024, respectively.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Tier 1 Capital Ratio was 11.17% compared to 10.71% and 10.36% at March 31, 2025, and June 30, 2024, respectively.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Total Risk-Based Capital Ratio was 13.27% compared to 13.09% and 12.65% at March 31, 2025, and June 30, 2024, respectively.

As previously disclosed, in April 2025, the Company called $10.0 million of its $40.0 million of fixed-to-floating subordinated debt that was originally issued in April 2015. These notes initially bore interest at a fixed rate of 6.00% and began repricing on a quarterly basis at a rate equal to the then-current three-month term SOFR plus 4.20561% after the April 2025 call date. The Company currently expects to retain the remaining $30.0 million of April 2015 notes, as well as the separate $35.0 million of fixed-to-floating rate subordinated notes that were issued in October 2020, which currently bear interest at a fixed rate of 4.375%, and are set to reprice at a rate of the then-current three-month term SOFR plus 4.265% beginning in October 2025. The April 2015 notes are callable on a quarterly basis going forward and the October 2020 notes become callable beginning in October 2025. The Company will continue to evaluate options relative to its outstanding subordinated debt, which may include redemption in part or in full, as well as replacing or refinancing the facilities.

**Credit Quality**

Non-performing loans were $32.4 million, or 0.72% of total loans, at June 30, 2025, as compared to $40.0 million, or 0.88% of total loans, at March 31, 2025, and $25.2 million, or 0.57% of total loans, at June 30, 2024. The decrease from March 31, 2025 reflects a reduction of approximately $3.7 million in non-performing loans associated with the foreclosure of a participated loan secured by real estate, as well as a $1.9 million partial charge-off of a credit facility for which a specific reserve was in place. Both the aforementioned foreclosed participated loan and the partially charged-off credit facility relate to a previously disclosed commercial business relationship that was placed on nonaccrual status in the fourth quarter of 2023. The increase in non-performing loans from June 30, 2024 was primarily driven by one commercial loan relationship that was placed on nonaccrual status during the third quarter of 2024. Net charge-offs were $4.1 million, representing 0.36% of average loans on an annualized basis, for the current quarter, as compared to $2.4 million, or an annualized 0.21% of average loans, in the first quarter of 2025 and $1.1 million, or an annualized 0.10%, in the second quarter of 2024.

At June 30, 2025, the allowance for credit losses on loans to total loans ratio was 1.04%, compared to 1.08% at March 31, 2025 and 0.99% at June 30, 2024.

Provision for credit losses was $2.6 million in the current quarter, compared to $2.9 million in the linked quarter and $2.0 million in the prior year quarter. Provision for credit losses on loans was $2.4 million in the current quarter, compared to $3.3 million in the first quarter of 2025, and $2.0 million in the second quarter of 2024. The allowance for unfunded commitments, also included in provision for credit losses as required by the current expected credit loss standard ("CECL"), totaled $179 thousand in the second quarter of 2025, $364 thousand in the first quarter of 2025, and $43 thousand in the second quarter of 2024. The provision for credit losses for the second quarter of 2025 was driven by a combination of factors, including improvement in the forecasted loss rate for pooled loans and a reduction in specific reserves, partly offset by higher net charge-offs.

The Company has remained strategically focused on the importance of credit discipline, allocating resources to credit and risk management functions as the loan portfolio has grown. The ratio of allowance for credit losses on loans to non-performing loans was 146% at June 30, 2025, 122% at March 31, 2025, and 174% at June 30, 2024, with the improvement from the end of the linked quarter reflective of the decrease in nonperforming loans reported at June 30, 2025.

**Subsequent Events**

The Company is required, under generally accepted accounting principles ("GAAP"), to evaluate subsequent events through the filing of its consolidated financial statements for the quarter ended June 30, 2025, on Form 10-Q. As a result, the

**Non-GAAP Financial Information** 

In addition to results presented in accordance with U.S. generally accepted accounting principles ("GAAP"), this press release contains certain non-GAAP financial measures. A reconciliation of these non-GAAP measures to GAAP measures is included in Appendix A to this document.

The Company believes that providing certain non-GAAP financial measures provides investors with information useful in understanding our financial performance, performance trends and financial position. Our management uses these measures for internal planning and forecasting purposes and we believe that our presentation and discussion, together with the accompanying reconciliations, allows investors, security analysts and other interested parties to view our performance and the factors and trends affecting our business in a manner similar to management. These non-GAAP measures should not be considered a substitute for GAAP measures, and we strongly encourage investors to review our consolidated financial statements in their entirety and not to rely on any single financial measure to evaluate the Company. Non-GAAP financial measures have inherent limitations, are not uniformly applied and are not audited. Because non-GAAP financial measures are not standardized, it may not be possible to compare these financial measures with other companies' non-GAAP financial measures having the same or similar names.
