Exhibit 99.1

FINANCIAL INSTITUTIONS, INC. ANNOUNCES THIRD QUARTER RESULTS

WARSAW, N.Y., October 29, 2020 – Financial Institutions, Inc. (Nasdaq:FISI) (the “Company” “we” or “us”), parent company of Five Star Bank (the “Bank”), SDN Insurance Agency, LLC (“SDN”), Courier Capital, LLC (“Courier Capital”) and HNP Capital, LLC (“HNP Capital”), today reported financial and operational results for the third quarter ended September 30, 2020.

Net income for the quarter was $12.3 million compared to $12.8 million for the third quarter of 2019. After preferred dividends, net income available to common shareholders was $11.9 million for the quarter, or $0.74 per diluted share, compared to $12.5 million, or $0.78 per diluted share, for the third quarter of 2019.

Pre-tax pre-provision income⁽¹⁾ was the highest in Company history at $19.2 million for the quarter, an increase of $283 thousand from the third quarter of 2019.

Third quarter 2020 net income and pre-tax pre-provision income reflect approximately $1.6 million of non-recurring expenses related to the previously announced closure of six bank branches and a staffing reduction.

President and Chief Executive Officer Martin K. Birmingham stated, “The past seven months have tested us, and I am proud to say that my teammates have responded extraordinarily well in continuing to deliver positive results for our customers, communities and shareholders. We generated record pre-tax pre-provision income in the quarter, driven by growth in net interest income, our diversified revenue streams and disciplined expense management.

“We continue to prudently lend and experienced 5.4% growth in our commercial mortgage portfolio, 2.0% growth in residential real estate loans and 1.5% growth in consumer indirect loans. Relationship managers are working closely with customers to assist with their needs and to ensure that we understand trends in our markets across all operating sectors. We continue to benefit from a stable Western New York economy and experienced low net charge-offs in the second and third quarters of 2020. Consistent with our cautiously optimistic outlook, we did increase the allowance for credit losses - loans to total loans ratio by five basis points.

“Re-entry plans are being implemented and we continue to monitor external COVID-19 indicators in our footprint to help guide decisions on future re-entry or closure to keep customers and associates safe. Additional associates are now working in our corporate offices; however, we expect to maintain occupancy levels in these locations at approximately 50% for the foreseeable future.

“I want to thank our associates for their tireless work to help our customers and communities impacted by COVID-19. Despite significant uncertainty and challenges, they continue to adapt and find innovative ways to work more efficiently and effectively. I am incredibly proud of our organization.”

Chief Financial Officer Justin K. Bigham added, “Net interest margin remained relatively constant at 3.22%, down one basis point from the linked quarter, despite a heightened Federal Reserve interest-earning cash balance and the full quarter impact of low-yielding Payroll Protection Program loans.

“We continue to focus on expense discipline. Third quarter expenses include non-recurring severance and real estate related restructuring charges of approximately $1.6 million in connection with the July announcement of branch closures and staffing reductions. Excluding these non-recurring expenses, the efficiency ratio for the quarter was just under 57%.

“Subsequent to quarter-end, we took advantage of the low interest rate environment and issued $35 million of 10-year fixed-to-floating rate subordinated notes. While we were confident that we had appropriate capital levels to effectively run our business, we determined that it would be prudent to access the debt markets at favorable rates to add capital for use in serving our customers, taking advantage of growth opportunities, and strengthening the Bank’s capital ratios. We also deemed it wise to add capital given uncertainty around long-term impacts of the global pandemic.”

Enterprise Standardization Program

The Company’s enterprise standardization program is focused on improving operational efficiency and enhancing future profitability. On July 17, 2020, in connection with the program, Five Star Bank announced changes to adapt to a full-service branch model to streamline retail branches to better align with shifting customer needs and preferences.

The announcement was the result of a nine-month comprehensive assessment of all lines of business and functional areas, conducted in partnership with a leading process improvement organization. The data-driven analysis identified, among other things, overlapping service areas, automation opportunities and streamlining of processes and operations that would enhance customer experiences and facilitate the long-term sustainability of current and future branches.

The July announcement included the consolidation of eleven branches into five, resulting in six branch closings and a reduction in staffing. The consolidations represent about ten percent of the branch network and impacted approximately six percent of the Company’s total workforce. These actions resulted in one-time expenses related to severance and real estate related charges of approximately $1.6 million in the third quarter of 2020. Expense savings of $2.6 million are anticipated on an annualized basis.

In early October, the Company announced the planned closure of one additional branch in January 2021. This location was not included in the branch consolidations announced in July, as alternative options were being considered and consolidation was not possible given its significant distance from other Five Star Bank branches. This closure is expected to result in one-time expenses related to severance costs and real estate related charges of approximately $130 thousand in the fourth quarter of 2020. Expected expense savings are anticipated at $340 thousand on an annualized basis.

The enterprise standardization program is not yet complete as we continue to evaluate activities and functions across the organization, focusing on ways to improve operational efficiency while enhancing the employee and customer experience.

Subordinated Note Issuance

On October 7, 2020, the Company completed a private placement of $35 million of fixed-to-floating rate subordinated notes due 2030 (the “Notes”) to qualified institutional buyers and accredited institutional investors. The Notes have a maturity date of October 15, 2030 and bear interest, payable semi-annually, at the rate of 4.375% per annum, until October 15, 2025. Commencing on that date, the interest rate will reset quarterly to an interest rate per annum equal to the then-current three-month secured overnight financing rate (“SOFR”) plus 426.5 basis points, payable quarterly until maturity.

The Company is entitled to redeem the Notes, in whole or in part, on any interest payment date on or after October 15, 2025, and in whole at any time upon certain other specified events. The Company intends to use the net proceeds for general corporate purposes, organic growth and to support regulatory capital ratios at Five Star Bank.

In connection with the issuance and sale of the Notes, the Company entered into a registration rights agreement with the purchasers of the Notes pursuant to which the Company has agreed to take certain actions to provide for the exchange of the Notes for subordinated notes that are registered under the Securities Act of 1933, as amended, with substantially the same terms as the Notes.

Net Interest Income and Net Interest Margin

Net interest income was $35.5 million for the quarter, an increase of $1.3 million from the second quarter of 2020 and $3.0 million higher than the third quarter of 2019.

Noninterest Income

Noninterest income was $12.4 million for the quarter compared to $9.8 million in the second quarter of 2020 and $12.4 million in the third quarter of 2019.

Noninterest Expense

Noninterest expense was $28.7 million in the quarter compared to $26.7 million in the second quarter of 2020 and $25.9 million in the third quarter of 2019.

Income Taxes

Income tax expense was $2.9 million for the quarter compared to $2.4 million for the second quarter of 2020 and $4.3 million for the third quarter of 2019. As a result of the Tax Cuts and Jobs Act, the Company estimated tax benefits and recorded a provisional amount in and for the year ended December 31, 2017. In the third quarter of 2019 an adjustment was made to the provisional amount resulting in incremental expense of approximately $600 thousand.

The effective tax rate was 19.3% for the quarter compared to 18.0% for the second quarter of 2020 and 25.0% for the third quarter of 2019. The Company’s effective tax rates differ from statutory rates because of interest income from tax-exempt securities, earnings on company owned life insurance and the impact of tax credit investments. The higher effective tax rate in the third quarter of 2019 was driven by the incremental expense described above. 

Balance Sheet and Capital Management

Total assets were $4.96 billion at September 30, 2020, up $278.3 million from June 30, 2020, and up $626.5 million from September 30, 2019.

Investment securities were $806.9 million at September 30, 2020, up $27.6 million from June 30, 2020, and up $25.2 million from September 30, 2019. The Company’s 2020 investment strategy has been to reinvest cash flow from the portfolio, coupled with deploying excess liquidity into cash flowing agency mortgage backed securities.

Total loans were $3.57 billion at September 30, 2020, up $82.7 million, or 2.4%, from June 30, 2020, and up $412.1 million, or 13.1%, from September 30, 2019. PPP loans of approximately $2 million and $269 million were funded in the third and second quarters of 2020, respectively. The loans carry a 1% interest rate and the Company recorded net PPP loan origination fees of approximately $7.4 million that are amortized over a 24-month period.

Total deposits were $4.36 billion at September 30, 2020, $370.9 million higher than June 30, 2020, and $778.7 million higher than September 30, 2019. The increase from June 30, 2020, was primarily the result of a seasonal increase in public deposits combined with growth in the reciprocal and brokered deposit portfolios. The Company utilized lower cost brokered deposit balances to pay off a maturing Federal Home Loan Bank term advance of $100 million during the quarter. The increase from September 30, 2019, was primarily due to growth in non-public demand and the reciprocal and brokered deposits portfolios. Public deposit balances represented 23% of total deposits at September 30, 2020, compared to 23% of total deposits at June 30, 2020, and 28% at September 30, 2019.

Short-term borrowings were $5.3 million at September 30, 2020, a decrease of $100.0 million from June 30, 2020 and a decrease of $206.1 million from September 30, 2019. The lower level of short-term borrowings at September 30, 2020, is attributable to growth in brokered deposits, which were utilized as a cost-effective alternative to Federal Home Loan Bank borrowings. Short-term borrowings and brokered deposits have historically been utilized to manage the seasonality of public deposits, which reached a seasonal high point during the third quarter. In February 2020, the Company entered a long-term brokered sweep arrangement as a stable alternative borrowing source to diversify the wholesale borrowing base.

Shareholders’ equity was $456.4 million at September 30, 2020, compared to $448.0 million at June 30, 2020, and $432.6 million at September 30, 2019. Common book value per share was $27.38 at September 30, 2020, an increase of $0.52 or 1.9% from $26.86 at June 30, 2020, and an increase of $1.42 or 5.5% from $25.96 at September 30, 2019. Tangible common book value per share⁽¹⁾ was $22.76 at September 30, 2020, an increase of $0.54 or 2.4% from $22.22 at June 30, 2020, and an increase of $1.50 or 7.1% from $21.26 at September 30, 2019.

During the third quarter of 2020, the Company declared a common stock dividend of $0.26 per common share. The dividend returned 35% of third quarter net income to common shareholders.

The Company’s regulatory capital ratios at September 30, 2020, compared to the prior quarter and prior year:

Credit Quality

Non-performing loans were $10.9 million at September 30, 2020, compared to $13.2 million at June 30, 2020, and $9.8 million at September 30, 2019. Net charge-offs were $488 thousand in the quarter, $298 thousand lower than the second quarter of 2020 and $4.1 million lower than the third quarter of 2019. The decrease from the prior year period is primarily attributable to the third quarter 2019 $3.0 million partial charge-off of a $5.6 million loan that had been classified as non-performing in the second quarter of 2019.

Foreclosed assets at September 30, 2020, were $3.0 million, an increase of $2.3 million from June 30, 2020, and an increase of $2.9 million from September 30, 2019. The increase as compared to both periods is attributable to one commercial credit that was partially charged off during the first quarter of 2020 and foreclosure occurred in the third quarter.

The ratio of annualized net charge-offs to total average loans was 0.06% in the current quarter, 0.09% in the second quarter of 2020 and 0.58% in the third quarter of 2019.

The Company adopted CECL effective January 1, 2020, which resulted in an increase to the allowance for credit losses - loans of $9.6 million and established a reserve for unfunded commitments of $2.1 million, for a total pre-tax cumulative effect adjustment of $11.7 million.

At September 30, 2020, the allowance for credit losses - loans to total loans ratio was 1.38% compared to 1.33% at June 30, 2020, and 1.00% at September 30, 2019. The PPP loans are fully guaranteed by the Small Business Administration. Excluding PPP loans, the allowance for credit losses - loans to total loans ratio was 1.49% at September 30, 2020, and 1.44% at June 30, 2020.

The provision for credit losses - loans was $3.6 million in the quarter compared to $3.7 million in the second quarter of 2020 and $1.8 million in the third quarter of 2019. Higher provisioning in 2020 reflects deterioration in the economic environment as a result of the impact of COVID-19, which adversely impacted our unemployment forecast, the designated loss driver for our CECL model. Provision for credit losses of $4.0 million in the third quarter of 2020 also includes a $461 thousand increase in the allowance for unfunded commitments.

The Company has remained strategically focused on the importance of credit discipline, allocating what we believe are the necessary resources to credit and risk management functions as the loan portfolio has grown. The total non-performing loans to total loans ratio was 0.31% at September 30, 2020, 0.38% at June 30, 2020, and 0.31% at September 30, 2019. The ratio of allowance for credit losses - loans to non-performing loans was 453% at September 30, 2020, compared to 351% at June 30, 2020, and 324% at September 30, 2019.
