Pathfinder Bancorp, Inc. Announces Fourth Quarter 2022

Net Income of $3.5 Million and Full Year Net Income of $12.9 Million

Results Include Record Earnings, Strong Loan Growth, Continued Solid Asset Quality

And Prudent Expense Management

Oswego, N.Y. — January 31, 2023 — Pathfinder Bancorp, Inc. (“Company”) (NASDAQ: PBHC), the holding company for Pathfinder Bank (“Bank”), announced fourth quarter 2022 net income available to common shareholders of $3.5 million, or $0.58 per basic and diluted share, compared to $3.9 million, or $0.64 per basic and diluted share, for the fourth quarter of 2021. For the full year 2022, total net income attributable to Pathfinder Bancorp, Inc. was $12.9 million, or $2.13 per basic and diluted share, compared to $12.4 million, or $2.07 per basic and diluted share, in 2021.

2022 Fourth Quarter and Full Year Performance Highlights

“Fourth quarter 2022 results were highlighted by strong revenue growth, focused expense management and continued strong credit quality metrics, which contributed to another record full year earnings and profitability in 2022. Heading into 2023, Pathfinder Bancorp is well positioned to continue our growth trajectory,” said James A. Dowd, President and Chief Executive Officer. “Full year net income available to common shareholders was up 4.2% compared to 2021, as we benefited from the increases in interest rates, continued loan growth and net interest margin expansion. We also continued to improve upon our key profitability metrics, with a strong return on average assets of 0.96% and return on average equity of 11.77% for the full year of 2022.”

“Our consistent focus throughout 2022 on enhancing our operating leverage continued to provide strong revenue growth of 6.3%, while keeping expenses stable, despite a difficult inflationary environment. In 2023, and in the face of significant economic uncertainty, our focus will continue to be on balancing effective expense management while concurrently making appropriate investments to support the future growth of the Company.”

“Our balance sheet growth included an increase of $65.3 million, or 7.8%, growth in total loans and our total deposits grew by more than $70.1 million, or 6.6%, over the prior full year. Deposit customer preferences caused a shift in the mix of deposits from noninterest bearing to interest-bearing deposits. Our deposit gathering efforts will continue to focus on transactional deposits and, consequently, reducing our reliance on time deposits. We are pleased with the outcome of our efforts in 2022 to control our funding costs, despite nearly unprecedented increases in interest rates, as the average cost of total interest-bearing liabilities increased only 15 basis points year-over-year.”

“Credit quality continues to be a strength of our bank with our $897.8 million loan portfolio producing a ratio of nonperforming loans to total loans of 1.00% at December 31, 2022, a level that was stable in comparison to 2021, and less than half of the 2.58% we reported in 2020. Our ratio of allowance for loan losses to nonperforming loans stood at 169.93% at year end. Loan loss provision returned to a more normalized level in 2022, and increased in the fourth quarter, as the Bank evaluated all risks associated with the loan portfolio and identified the need for certain credit downgrades on a small number of large loan relationships.”

“Our projected loan pipeline volume remains solid at year end. However, we anticipate loan demand slowing from the robust levels experienced following the pandemic and we will continue to maintain our prudent and consistent underwriting standards as we move forward. Our Central New York markets remain vibrant and we continue to take multiple strategic steps to bring about further growth for the Company. We were happy to announce the opening of our newest branch in the Southwest Corridor of the City of Syracuse during the fourth quarter of 2022. We are certain that this branch location will allow us to better serve our growing customer base in that portion of our existing footprint and will provide a range of community banking services to an under-served neighborhood. We continue to believe that our strong financial performance, dedicated and highly capable team and healthy capital position leaves us well-positioned for 2023 and beyond.”

Income Statement for the Quarter and Year Ended December 31, 2022

Fourth quarter 2022 net income was $3.5 million, a decrease of $350,000, or 9.0% from $3.9 million in the fourth quarter of the previous year. Net interest income, before provision for loan losses, increased by $1.5 million, or 14.9%, in the fourth quarter of 2022 to $11.2 million, compared to $9.7 million for the same quarter in 2021. The increase in net interest income between comparable quarters was primarily due to the $3.8 million, or 34.3%, increase in interest and dividend income in the fourth quarter of 2022. Interest and dividend income increased to $15.0 million, compared to $11.2 million in the same quarter in 2021. These improvements in interest and dividend income were partially offset by an increase in interest expense for the fourth quarter of 2022 of $2.4 million, or 163.9%, to $3.8 million, from $1.5 million for the prior year quarter.

The quarter-over-quarter improvement in net interest income before provision for loan losses, discussed above, was more than offset by an increase in the provision for loan losses recorded in the fourth quarter of 2022. The Bank reported a provision for loan losses of $1.9 million for the fourth quarter of 2022, compared to a credit to provision for loan losses of $1.0 million for the fourth quarter of 2021. Therefore, net interest income, after provision for loan losses, decreased by $1.5 million, or 13.7%, in the fourth quarter of 2022 to $9.3 million, compared to $10.8 million for the same quarter in 2021.

Noninterest income increased in the fourth quarter of 2022 to $1.9 million, an increase of $448,000, or 31.9%, compared to the same quarter in 2021. Total revenues after provision for loan losses therefore decreased $1.0 million, or -8.4%, to $11.2 million from $12.2 million in the same quarter of the previous year. Noninterest expense increased in the fourth quarter of 2022 by $19,000, remaining essentially unchanged from the same quarter in 2021 at $7.2 million.

Net income for the full year ended December 31, 2022 was $12.9 million, an increase of 524,000, or 4.2% from $12.4 million in 2021. Net interest income, before provision for loan losses, increased by $3.1 million, or 8.1%, in 2022 to $41.4 million, compared to $38.3 million in 2021. The increase in net interest income between the two years was primarily due to the $5.3 million, or 11.5%, increase in interest and dividend income in 2022. Interest and dividend income increased to $51.1 million, compared to $45.8 million in the year ended December 31, 2021. These improvements in interest and dividend income were partially offset by an increase in interest expense in 2022 of $2.2 million, or 28.7%, to $9.7 million from $7.5 million for the prior year.

The year-over-year improvement in net interest income before provision for loan losses, discussed above, was partially offset by an increase in the provision for loan losses recorded in 2022. The Bank reported a provision for loan losses of $2.8 million in 2022, compared to a provision for loan losses of $1.0 million in the previous year. Therefore, net interest income, after provision for loan losses, increased by $1.4 million, or 3.7%, in 2022 to $38.6 million, compared to $37.3 million in 2021.

Noninterest income decreased in 2022 to $5.9 million, a decrease of $317,000, or 5.1%, compared to 2021. Total revenues after provision for loan losses therefore increased $1.1 million, or 2.4%, to $44.6 million from $43.5 million in the previous year. Noninterest expense increased in 2022 by $1.4 million, or 5.0%, increasing from $27.5 million in 2021 to $28.9 million in 2022.

Components of Net Interest Income

Fourth quarter 2022 net interest income was $11.2 million, an increase of $1.5 million, or 14.9%, compared to $9.7 million for the same quarter in 2021. Interest and dividend income in the 2022 fourth quarter was $15.0 million, compared to $11.2 million in the fourth quarter of 2021. The increase in interest and dividend income between comparable quarters was a result of a 41-basis-point increase in the average loan yield, and a $38.8 million increase in average taxable investment securities combined with a 133-basis-point increase in the average yield on those instruments. Partially offsetting those increases was an 82-basis-point increase in rates paid on interest-bearing liabilities. Total interest expense for the fourth quarter of 2022 was $3.8 million, an increase of $2.4 million, or 163.9%, from $1.5 million for the prior year quarter. The increase in the quarterly interest expense was primarily a result of the increase in cost of deposits resulting from the rapidly rising interest rate environment. The deposit mix included a $108.7 million increase in average time deposit balances combined with a 115-basis-point increase in the average interest rate paid on those deposits. The resultant net interest margin for the fourth quarter of 2022 was 3.42%, a 14-basis-point increase compared to a net interest margin of 3.28% for the fourth quarter of 2021.

Net interest income for the full year of 2022 increased $3.1 million, or 8.1%, to $41.4 million compared to $38.3 million for the full year of 2021. Interest and dividend income for the full year ended December 31, 2022 was $51.1 million, an increase of $5.3 million, or 11.5%, compared to $45.8 million for 2021. The increase was due to a $38.8 million increase in average taxable investment securities and a $36.3 million, or 4.4%, increase in average loan balances compared to the prior year. Partially offsetting these increases in interest income in 2022, as compared to the previous year, was an increase in interest expense to $9.7 million, representing an increase of $2.2 million, or 28.7%, from the prior year period. This increase in interest expense was primarily due to an increase in time deposit balances, along with a 22 basis point increase in the interest rate paid on those deposits. Full year 2022 net interest margin of 3.24% was up three basis points from 3.21% for the twelve months ended December 31, 2021.

The following table details the components of net interest income for the three and twelve months ended December 31, 2022 and 2021:

Paycheck Protection Program Discussion

From April 2020 to May 2021, the Company participated in all phases of the Paycheck Protection Program (“PPP”) as administered by the U.S. Small Business Administration (the “SBA”). PPP loans were substantially guaranteed as to timely repayment by the SBA and had unique forgiveness features whereby loan principal amounts may be discharged, for the benefit of the borrowers, by direct payments from the SBA to the lending institution holding the indebtedness. The Company has received both interest (calculated at a stated rate of 1%) and various levels of fee income related to the origination of PPP loans. The total outstanding balance of PPP loans was $203,000 at December 31, 2022, a decline of $19.6 million from the $19.8 million outstanding balance of PPP loans at December 31, 2021. Information related to the Company’s PPP loans are included in the following tables:

Provision for Loan Losses

The Bank reported a provision for loan losses of $1.9 million for the fourth quarter of 2022, compared to a credit to provision for loan losses of $1.0 million for the fourth quarter of 2021. During the fourth quarter of 2021, the Bank evaluated all risks associated with the loan portfolio and reduced its allowance for loan losses by a net $1.0 million, based on all information available at that time. The increase in the provision for loan losses in the fourth quarter of 2022 was primarily due to the results of a similar loan portfolio evaluation that indicated the need for certain downgrades of four large loan relationships totaling approximately $12.0 million. Management believes that these downgrades are not reflective of any broader patterns of loan quality deterioration within the Bank’s loan portfolios. Certain credit sensitive portfolios continue to be carefully monitored, and the Bank will consistently apply its loan classification and reserve building methodologies to the analysis of these portfolios. The provision for loan losses for the full year of 2022 was $2.8 million, compared to $1.0 million in 2021.

In June 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (ASU) 2016-13, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, requiring financial institutions, such as the Bank, to adopt the Current Expected Credit Loss (“CECL”) according to a specified implementation timeline that was based on the size of the reporting entity. In order to meet this requirement, the Bank adopted the CECL methodology for calculating its Allowance for Credit Losses (“ACL”) on January 1, 2023. The transition adjustment upon the adoption of CECL will be accounted for as a one-time charge to retained earnings and does not impact earnings per share in either 2022 or 2023. Management estimates that the required CECL transition adjustment will not exceed $1.7 million, after tax effects. This one-time adjustment will translate to a reduction of approximately $0.28 per share in the Company’s tangible book value (TBV), after tax effects as of the adoption date.

Noninterest Income

Fourth quarter 2022 noninterest income was $1.9 million, an increase of $448,000, or 31.9%, compared to $1.4 million for the same three-month period in 2021. Noninterest income was $5.9 million for the full year 2022, compared to $6.2 million for 2021.

The following table details the components of noninterest income for the three and twelve months ended December 31, 2022, and 2021:

Noninterest income before (losses) gains increased $579,000, or 43.6%, in the fourth quarter of 2022, primarily due to the recognition of $660,000 in historical tax credit subsidies made available upon the completion of the Bank’s new branch location in Syracuse, NY. Absent that nonrecurring revenue addition in the fourth quarter of 2022, noninterest income before (losses) gains would have decreased $81,000, or 6.1% in the fourth quarter of

5

2022, as compared to the same quarter in 2021. This decline in noninterest income was primarily due to a decline of $132,000, or 34.6%, in service charges on deposit accounts that was due principally to a reduction in certain fee structures that the Bank enacted in January 2022 in response to the locally competitive market. All other categories of noninterest income before (losses) gains increased $51,000 in aggregate during the fourth quarter of 2022, as compared to the same quarter in 2021, due to individually immaterial net increases in other recurring sources of noninterest income.

During the fourth quarter of 2022, the Bank recognized an impairment charge of $380,000 related to a real estate property investment that was newly categorized as available-for-sale. Partially offsetting this unrealized loss recognition, the Company also recognized unrealized gains on equity securities, held by the holding company, due to increases in the securities’ net asset values.

Noninterest income before (losses) gains increased $676,000, or 12.86%, for the full year 2022, primarily due to the fourth quarter recognition of $660,000 in historical tax credit subsidies made available upon the completion of the Bank’s new branch location in Syracuse, NY. Absent that nonrecurring revenue addition in the fourth quarter of 2022, noninterest income before (losses) gains increased $16,000, or 0.3%, for the full year 2022, as compared to 2021. Of note, service charges on deposit accounts declined $338,000, or 23.1%, in 2022, as compared to the previous year due to the reduction in the Bank’s fee structures discussed above. All other categories of recurring noninterest income before (losses) gains, excluding the $660,000 historical tax credit recorded in the fourth quarter of 2022, increased $354,000 in aggregate during 2022, as compared to 2021, due to individually immaterial net increases in other recurring sources of noninterest income.

Noninterest Expense

Total noninterest expense for the fourth quarter of 2022 was $7.2 million, essentially unchanged from the same three-month period in 2021. Noninterest expense for the fourth quarter of 2022, in comparison to the same quarter in the previous year, was driven by increases in salaries and benefits expense of $74,000, or 1.9%, partially offset by aggregate decreases in all other expense categories of $205,000, or 6.3%. The $74,000 increase in salaries and benefits expense for the three months ended December 31, 2022, as compared to the same three month period in 2021, was primarily due to increases in individual staff salaries and certain commissions paid related to insurance and investment services activities. Additionally, salaries and benefits expenses increased due to additions to staff headcount concentrated primarily in the loan servicing areas and within the Bank's branch system. Staffing increases in the Bank's branch system were made as a result of the opening of the Bank's eleventh branch in November 2022. During 2022, the Company increased its salary structure where it was deemed appropriate in order to effectively respond to inflationary and competitive pressures within our marketplace to recruit and retain talent.

Total noninterest expense for the full year 2022 was $28.9 million, an increase of $1.4 million, or 5.0%, compared with $27.5 million in 2021. The increase in noninterest expenses in 2022, as compared to 2021, was primarily a result of an increase in salaries and employee benefits expense of $1.6 million, or 11.4%, that was primarily comprised of an $737,000, or 7.2%, increase in salaries, a $530,000 reduction in the level of deferred employee-related expenses related to loan origination volume declines following the cessation of the PPP, and a $370,000 increase in all other salaries and employee benefit expenses.

The following table details the components of noninterest expense for the three and twelve-months ended December 31, 2022 and 2021:

Balance Sheet on December 31, 2022

The Company’s total assets on December 31, 2022 were $1.40 billion, an increase of $114.7 million, or 8.9%, from $1.29 billion on December 31, 2021. This increase was primarily driven by increased loan balances and an increase in held-to-maturity securities. Total loans of $897.8 million increased by $65.3 million, or 7.9%, compared with $832.5 million on December 31, 2021. Investment securities totaled $394.0 million, an increase of $37.6 million compared to $356.4 million on December 31, 2021.

Total deposits on December 31, 2022 were $1.13 billion, an increase of $70.0 million, or 6.6%, from $1.06 billion, at December 31, 2021. Interest-bearing deposits of $941.7 million at 2022 year end were up by $78.0 million, or 9.1%, while noninterest-bearing deposits totaled $183.7 million at December 31, 2022, a decrease of $8.0 million, or 4.2%, from the 2021 year end. The decrease in noninterest-bearing deposits was the result of the rapidly rising interest rate environment which increased the competition for deposits in general and caused depositor preferences to shift from transactional deposits to time deposits as the year progressed.

Shareholders’ equity was $111.0 million at December 31, 2022, reflecting an increase of $709,000, or 0.64%, compared with $110.3 million at December 31, 2021. The increase was primarily a result of a $10.4 million or 17.0% increase in retained earnings, offset by an increase of $10.9 million in accumulated other comprehensive loss, due to unrealized temporary losses on investment securities categorized as available-for-sale, and $1.2 million in declared dividend distributions.

Asset Quality

The Bank continued to maintain strong asset quality metrics, as measured by annualized net loan charge-offs to average loans, for fourth quarter 2022 of 0.04%. Annualized net loan charge-offs to average loans were 0.12% for the fourth quarter 2021.

Nonperforming loans remained stable at December 31, 2022, as compared to December 31, 2021. Management continues to monitor all nonaccrual loans closely and has incorporated our current estimate of the ultimate collectability of these loans into the reported allowance for loan losses at December 31, 2022.

7

The following table summarizes nonaccrual loans by category and status at December 31, 2022:

The allowance for loan losses to non-performing loans at December 31, 2022 was 169.93%, compared with 155.99% at December 31, 2021. The change in the allowance for loans losses to non-performing loans is reflective of the changes in nonaccrual loans discussed above and compared to a reserve release during the fourth quarter of 2021.

Cash Dividend Declared

On December 27, 2022, the Company announced that its Board of Directors declared a cash dividend of $0.09 per share on the Company's voting common and non-voting common stock, and a cash dividend of $0.09 per notional share for the issued warrant relating to the fiscal quarter ended December 31, 2022. The dividend will be payable to all shareholders of record on January 17, 2023 and will be paid on February 10, 2023. Based on the closing price of the Company’s common stock of $19.14 on December 30, 2022, the implied dividend yield is 1.9%. The quarterly cash dividend of $0.09 equates to a dividend payout ratio of 20.9%.
