Old Second Bancorp, Inc. Reports Fourth Quarter 2024 Net Income of $19.1 Million,

or $0.42 per Diluted Share

AURORA, IL, January 22, 2025 – Old Second Bancorp, Inc. (the “Company,” “Old Second,” “we,” “us,” and “our”) (NASDAQ: OSBC), the parent company of Old Second National Bank (the “Bank”), today announced financial results for the fourth quarter of 2024.  Our net income was $19.1 million, or $0.42 per diluted share, for the fourth quarter of 2024, compared to net income of $23.0 million, or $0.50 per diluted share, for the third quarter of 2024, and net income of $18.2 million, or $0.40 per diluted share, for the fourth quarter of 2023. Adjusted net income, a non-GAAP financial measure that excludes certain nonrecurring items, as applicable, was $20.3 million, or $0.44 per diluted share, for the fourth quarter of 2024, compared to $23.3 million, or $0.51 per diluted share, for the third quarter of 2024, and $19.1 million, or $0.42 per diluted share, for the fourth quarter of 2023. The adjusting item impacting the fourth quarter of 2024 included $1.5 million of transaction-related expenses due to the early December 2024 purchase of five branches from First Merchants Bank (“FRME”). The adjusting items impacting the third quarter of 2024 included $471,000 of FRME transaction-related expenses; the adjusting items impacting the fourth quarter of 2023 results included $1.2 million of nonrecurring litigation expense.  See the discussion entitled “Non-GAAP Presentations” below and the tables beginning on page 17 that provide a reconciliation of each non-GAAP measure to the most comparable GAAP equivalent.

Net income decreased $3.8 million in the fourth quarter of 2024 compared to the third quarter of 2024. The decrease was primarily due to a $1.5 million increase in provision for credit losses, as well as a $5.0 million increase in noninterest expense in the fourth quarter of 2024, compared to the prior linked quarter.  These reductions to the current quarter’s net income were partially offset by a $1.0 million increase in net interest and dividend income and a $1.0 million increase in noninterest income. Net income increased $885,000 in the fourth quarter of 2024 compared to the fourth quarter of 2023, primarily due to a decrease of $4.5 million in provision for credit losses, an increase in noninterest income of $2.9 million, and an increase in net interest income of $349,000. The year over year fourth quarter increase is partially offset by a $7.3 million increase in noninterest expenses.

Operating Results

Fourth quarter 2024 net income was $19.1 million, reflecting a $3.8 million decrease from the third quarter of 2024, and an increase of $885,000 from the fourth quarter of 2023.  Adjusted net income, as defined above, was $20.3 million for the fourth quarter of 2024, a decrease of $3.0 million from adjusted net income for the third quarter of 2024, and an increase of $1.2 million from adjusted net income for the fourth quarter of 2023.
Net interest and dividend income was $61.6 million for the fourth quarter of 2024, reflecting an increase of $1.0 million, or 1.7%, from the third quarter of 2024, and an increase of $349,000, or 0.6%, from the fourth quarter of 2023.
--- ---
We recorded a net provision for credit losses of $3.5 million in the fourth quarter of 2024 compared to a net provision for credit losses of $2.0 million in the third quarter of 2024, and a net provision for credit losses of $8.0 million in the fourth quarter of 2023.
--- ---
Noninterest income was $11.6 million for the fourth quarter of 2024, an increase of $1.0 million, or 9.7%, compared to $10.6 million for the third quarter of 2024, and an increase of $2.9 million, or 33.0%, compared to $8.7 million for the fourth quarter of 2023.
--- ---
Noninterest expense was $44.3 million for the fourth quarter of 2024, an increase of $5.0 million, or 12.8%, compared to $39.3 million for the third quarter of 2024, and an increase of $7.3 million, or 19.7%, compared to $37.0 million for the fourth quarter of 2023.

We had a provision for income tax of $6.3 million for the fourth quarter of 2024, compared to a provision for income tax of $6.9 million for the third quarter of 2024 and a provision for income tax of $6.7 million for the fourth quarter of 2023. The effective tax rate for each of the periods presented was 24.7%, 23.1%, and 26.9%, respectively. The reduction in the effective tax rate in the third and fourth quarters of 2024, compared to the fourth quarter of 2023, reflects the new state ruling regarding tax rate apportionment factors related to income generated from securities or loans originated in other states.
On January 21, 2025, our Board of Directors declared a cash dividend of $0.06 per share of common stock, payable on February 10, 2025, to stockholders of record as of January 31, 2025.

Chairman, President and Chief Executive Officer Jim Eccher said “Old Second reported strong results in the fourth quarter of 2024 with exceptional profitability and positive trends in a number of verticals. Tangible book value per share increased by more than fifteen percent on a year over year basis inclusive of the dilution associated with a branch purchase transaction in the fourth quarter. We believe we are being proactive in addressing commercial loans facing deterioration from higher interest rates, declining appraisal values and cash flow pressures. Importantly, classified and criticized loans have declined meaningfully both year over year and linked quarter and are now at their lowest levels since June 2022. We have seen previously identified loans work toward resolution and the pace of upgrades relative to downgrades has improved dramatically. Losses realized in the fourth quarter in both the loan portfolio and in OREO write downs drive the expectation of further meaningful reduction in nonperforming assets early in 2025. Exceptional profitability has afforded Old Second the opportunity to aggressively address problem acquired credits and position us to deliver improved performance in 2025. Fourth quarter return on average assets and return on average tangible common equity were 1.34% and 13.79%, respectively, the tax equivalent net interest margin was stable at 4.68% and the efficiency ratio is a very healthy 57.12%. This strong bottom-line performance and a well-positioned balance sheet drove an increase in the tangible common equity capital ratio to 10.04% from 8.53% last year end, in light of the strength of the balance sheet and resilient income statement and margin trends. In summary, we are proud of the sustainability of our performance this year and believe we are well positioned to capitalize on growth opportunities that we believe will come our way in the near future.”

Asset Quality & Earning Assets

Nonperforming loans, comprised of nonaccrual loans plus loans past due 90 days or more and still accruing, totaled $30.3 million at December 31, 2024, $52.3 million at September 30, 2024, and $68.8 million at December 31, 2023.  Nonperforming loans, as a percent of total loans, were 0.8% at December 31, 2024, 1.3% at September 30, 2024, and 1.7% at December 31, 2023.  The decrease in the fourth quarter of 2024 for nonperforming loans is driven by net nonaccrual loans outflows of $23.3 million, partially offset by $1.3 million of net inflows of loans past due 90 days or more and still accruing. Nonaccrual loan outflows consist of $8.9 million paid off, largely driven by one commercial real estate – investor loan of $6.6 million, a $13.0 million commercial real estate – owner occupied relationship transferred to OREO, $8.3 million of partial principal reductions from payments, and $3.2 million of upgrades. The nonaccrual outflows were partially offset by additions of $10.0 million, primarily driven by one large commercial real estate – owner occupied relationship.
Total loans were $3.98 billion at December 31, 2024, reflecting a decrease of $9.7 million compared to September 30, 2024, and a decrease of $61.6 million compared to December 31, 2023. The decrease year over year was largely driven by the declines in commercial, commercial real estate-owner occupied and multifamily portfolios.  Average loans (including loans held-for-sale) for the fourth quarter of 2024 totaled $4.00 billion, reflecting an increase of $36.3 million from the third quarter of 2024, and a decrease of $13.4 million from the fourth quarter of 2023.
--- ---
Available-for-sale securities totaled $1.16 billion at December 31, 2024, compared to $1.19 billion at September 30, 2024 and December 31, 2023.  The unrealized mark to market loss on securities totaled $68.6 million as of December 31, 2024, compared to $56.2 million as of September 30, 2024, and $84.2 million as of December 31, 2023, due to market interest rate fluctuations as well as changes year over year in the composition of the securities portfolio. During the quarter ended December 31, 2024, we had security purchases of $84.9 million, and security maturities, calls and paydowns of $101.2 million, compared to security purchases of $22.7 million and security calls and paydowns of $31.3 million during the quarter ended September 30, 2024.  During the quarter ended December 31, 2023, we had security purchases of $9.2 million and $81.6 million of maturities, calls, and paydowns, which resulted in net realized losses of $2,000.  We may continue to buy and sell strategically identified securities as opportunities arise.

^1^ Tax equivalent (TE) basis is calculated using a marginal tax rate of 21% in 2024 and 2023. See the discussion entitled “Non-GAAP Presentations” below and the tables beginning on page 17 that provide a reconciliation of each non-GAAP measure to the most comparable GAAP equivalent.

^2^ Interest income from loans is shown on a tax equivalent basis, which is a non-GAAP financial measure as discussed in the table on page 17, and includes loan fee income of $140,000 for the fourth quarter of 2024, loan fee expense of $155,000 for the third quarter of 2024, and loan fee expense of $922,000 for the fourth quarter of 2023. Nonaccrual loans are included in the above stated average balances.

The decreased yield of 11 basis points on interest earning assets compared to the linked period was driven by repricing within the loan and taxable securities portfolios. Changes in the market interest rate environment impact earning assets at varying intervals depending on the repricing timeline of loans, as well as the securities maturity, paydown and purchase activities.

​ 4

The year over year increase of 17 basis points on interest earning assets was primarily driven by overall increases to benchmark interest rates over the past twelve months, primarily impacting variable rate loans and securities. Average balances of securities available for sale decreased $12.0 million in the fourth quarter of 2024 compared to the prior year like quarter, while the tax equivalent yield on the securities available for sale portfolio increased 21 basis points year over year due to variable security rate resets.

Average balances of interest-bearing deposit accounts have increased moderately since the third quarter of 2024 through the fourth quarter of 2024, from $2.79 billion to $2.89 billion, as NOW, money market, savings, and time account average balances all increased due to the deposits acquired from the FRME branch purchase. We have continued to control the cost of funds over the periods reflected by slowing the pace of change with the rate of overall interest-bearing deposits decreasing to 141 basis points for the quarter ended December 31, 2024, from 148 basis points for the quarter ended September 30, 2024, but the cost of deposits increased from 89 basis points for the quarter ended December 31, 2023. A 15 basis point decrease in the cost of money market funds for the quarter ended December 31, 2024 compared to the prior linked quarter, and a 46 basis point increase compared to the prior year like quarter, drove a significant portion of the overall decrease from the prior linked quarter and the increase from the prior year like quarter. Although there was an increase in transactional account average balances from the prior year like quarter for NOW and savings accounts, average rates paid on these combined balances remained relatively steady. Average rates paid on time deposits for the quarter ended December 31, 2024 decreased by 16 basis points and increased 96 basis points in the quarter over linked quarter and year over year quarters, respectively, primarily due to CD rate specials that were offered.

Borrowing costs decreased in the fourth quarter of 2024, compared to the third quarter of 2024, primarily due to the $100.7 million decrease in average other short-term borrowings stemming from a decrease in average daily FHLB advances over the prior linked quarter as a majority of this borrowing was paid down in December 2024. The decrease of $185.9 million year over year of average FHLB advances was based on daily liquidity needs, and was the primary driver of the $2.9 million decrease to interest expense on other short-term borrowings. Subordinated and junior subordinated debt interest expense were essentially flat over each of the periods presented.

Our net interest margin, for both GAAP and TE presentations, was relatively static over the periods presented above. Our net interest margin (GAAP) increased four basis points to 4.66% for the fourth quarter of 2024, compared to 4.62% for the third quarter of 2024, and increased seven basis points compared to 4.59% for the fourth quarter of 2023.  Our net interest margin (TE) increased four basis points to 4.68% for the fourth quarter of 2024, compared to 4.64% for the third quarter of 2024, and increased six basis points compared to 4.62% for the fourth quarter of 2023.  The increase in the fourth quarter of 2024, compared to the prior linked quarter, was driven by market interest rates as well as the composition of assets and liabilities. Although interest income and expense both decreased compared to the prior linked quarter, interest expense decreased at a higher rate leading to increased net interest income. The net interest margin increased in the fourth quarter of 2024, compared to the prior year like quarter, primarily due to higher security and loan yields on lower average balances, partially offset by the increase in costs of interest-bearing deposits. See the discussion entitled “Non-GAAP Presentations” and the tables beginning on page 17 that provide a reconciliation of each non-GAAP measure to the most comparable GAAP equivalent.

Noninterest income increased $1.0 million, or 9.7%, in the fourth quarter of 2024, compared to the third quarter of 2024, and increased $2.9 million, or 33.0%, compared to the fourth quarter of 2023.  The increase from the third quarter of 2024 was primarily driven by a $1.4 million increase in residential mortgage banking revenue due to an increase of $1.3 million in MSRs mark to market valuation. Also contributing to the increase during the quarter was a $512,000 increase in wealth management income primarily due to growth in estate fees. Partially offsetting the increase in noninterest income from the prior quarter was a $744,000 decrease in other income primarily due to various refunds and incentive bonuses received in the third quarter of 2024.

The increase in noninterest income of $2.9 million in the fourth quarter of 2024, compared to the fourth quarter of 2023, is primarily due to a $1.8 million increase in residential mortgage banking revenue mainly due to a $1.7 million increase in MSRs mark to market valuations, a $699,000 increase in wealth management income primarily due to growth in advisory fees and estate fees, and a $226,000 increase in the cash surrender value of BOLI.

^1^The efficiency ratio shown in the table above is a GAAP financial measure calculated as noninterest expense, excluding amortization of core deposits and OREO expenses, divided by the sum of net interest income and total noninterest income less net gains or losses on securities, death benefit realized on BOLI, and mark to market gains or losses on MSRs.

^2^ The adjusted efficiency ratio shown in the table above is a non-GAAP financial measure calculated as noninterest expense, excluding amortization of core deposits, OREO expenses, and acquisition expenses, divided by the sum of net interest income on a fully tax equivalent basis, total noninterest income less net gains or losses on securities, death benefit realized on BOLI, mark to market gains or losses on MSRs, and includes a tax equivalent adjustment on the change in cash surrender value of BOLI.  See the discussion entitled “Non-GAAP Presentations” below and the table on page 17 that provides a reconciliation of this non-GAAP financial measure to the most comparable GAAP equivalent.

Noninterest expense for the fourth quarter of 2024 increased $5.0 million, or 12.8%, compared to the third quarter of 2024, and increased $7.3 million, or 19.7%, compared to the fourth quarter of 2023.  The increase in the fourth quarter of 2024 compared to the third quarter of 2024, was attributable to a $937,000 increase in salaries and employee benefits, with increases reflected primarily in officers’ incentives due to a higher projection of year end accruals based on our bank’s performance utilizing measures previously approved by our compensation committee, deferred executive compensation due to changes in market interest rates, and increases in salaries based on increased base salary rates.  Also contributing to the increase in noninterest expense in the fourth quarter of 2024 was a $581,000 increase in occupancy, furniture and equipment, a $284,000 increase in computer and data processing expenses, a $403,000 increase in consulting & management fees, and a $400,000 increase in other expenses, all due to transaction-related costs incurred related to our purchase of five bank branches from FRME. Other notable increases during the quarter consisted of a $458,000 increase in legal fees due to loan related legal costs, and a $1.8 million increase in other real estate owned expense, net, as a $1.7 million OREO valuation reserve expense was recorded based on valuation write downs on two of our OREO properties.

The year over year increase in noninterest expense is primarily attributable to a $4.2 million increase in salaries and employee benefits, primarily due to increases in annual base salary rates, officers’ incentives, and deferred employee compensation due to market interest rate changes.  Also contributing to the increase was a $640,000 increase in occupancy, furniture and equipment, a $368,000 increase in computer and data processing, and a $327,000 increase in consulting & management fees, all primarily due to transaction-related costs incurred related to our branch purchase from FRME. Other increases year over year were a $432,000 increase in legal fees due to loan related legal costs, and a $1.8 million increase in other real estate owned expense, net, as a $1.7 million OREO valuation reserve expense was recorded based on valuation write downs on two of our OREO properties. Partially offsetting the increases in noninterest expense in the fourth quarter of 2024, compared to the fourth quarter of 2023, was a $731,000 decrease in other expenses primarily due to a $1.2 million litigation expense recorded in the fourth quarter of 2023 related to an overdraft case, which was settled in 2025 at the total that was originally accrued in 2023.

Total loans decreased by $9.7 million at December 31, 2024, compared to September 30, 2024, and decreased $61.6 million for the year over year period.  The decrease in total loans in the fourth quarter of 2024 compared to the prior linked quarter was due to increased paydowns, net of originations, over the fourth quarter, primarily in commercial real estate-owner occupied and multifamily loans, and increased transfers into OREO for $13.0 million. The year over year reduction in loans is primarily due to paydowns, net of originations, in commercial real estate – owner occupied of $113.3 million, commercial of $41.2 million, multifamily of $50.4 million, partially offset by lease originations, net of paydowns, of $93.5 million, commercial real estate – investor loan growth of $44.4 million and construction loan growth of $36.3 million. Increases were noted in the leases segment in the fourth quarter of 2024 compared to the prior linked quarter and compared to the prior year like period primarily due to an expansion of this product line over the past year.

The portfolio’s decrease in the fourth quarter of 2024, compared to the prior quarter-end, was due to $101.2 million in maturities, calls, and paydowns, as well as an increase in unrealized losses of $12.4 million, partially offset by $84.9 million in purchases. Net unrealized losses at December 31, 2024 were $68.6 million, compared to $56.2 million at September 30, 2024 and $84.2 million at December 31, 2023. The year over year decrease in net unrealized losses is due to changes in the market interest rate environment as well as the impact of security paydowns and purchases undertaken to further reduce the portfolio’s interest rate sensitivity. The portfolio continues to consist of high quality fixed-rate and floating-rate securities, with more than 99% of publicly issued securities rated AA or better.

Classified loans as of December 31, 2024 decreased by $20.8 million from September 30, 2024, and decreased by $40.8 million from December 31, 2023. The net decrease from the third quarter of 2024 was primarily driven by outflows of $9.4 million of paid off loans, $6.1 million of loans upgraded, $9.7 million of principal reductions from payments, and $13.0 million transferred to OREO. The decrease in classified loans in the fourth quarter of 2024 was partially offset by additions of $17.3 million, primarily driven by one construction loan totaling $13.6 million. Remediation work continues on these credits, with the goal of cash flow improvements with increased tenancy.

Allowance for Credit Losses on Loans and Unfunded Commitments

At December 31, 2024, our allowance for credit losses (“ACL”) on loans totaled $43.6 million, and our ACL on unfunded commitments, included in other liabilities, totaled $1.9 million.  In the fourth quarter of 2024, we recorded provision expense of $3.5 million based on historical loss rate updates, our assessment of nonperforming loan metrics and trends, as well as estimated future credit losses. The fourth quarter’s provision expense consisted of a $4.1 million provision for credit losses on loans, and a $600,000 reversal of provision for credit losses on unfunded commitments.  The decrease in ACL on unfunded commitments was primarily due to an adjustment to historical benchmark assumptions, such as funding rates and the period used to forecast those rates, within the ACL calculation.  We recorded net charge offs of $4.9 million in the fourth quarter of 2024, primarily within the commercial portfolio. The third quarter 2024 provision expense of $2.0 million consisted of a $2.0 million provision for credit losses on loans, and an immaterial provision for credit losses on unfunded commitments. We recorded net recoveries of $155,000 in the third quarter of 2024. In the fourth quarter of 2023, we recorded a provision expense of $8.0 million, which consisted of an $8.0 million provision for credit losses on loans and an immaterial provision for credit losses on unfunded commitments. We recorded net charge-offs of $15.5 million in the fourth quarter of 2023. Our ACL on loans to total loans was 1.1% as of December 31, 2024, September 30, 2024, and December 31, 2023.

The ACL on unfunded commitments totaled $1.9 million as of December 31, 2024, $2.5 million as of September 30, 2024, and $2.7 million as of December 31, 2023.

Deposits

Total deposits were $4.77 billion at December 31, 2024, an increase of $303.3 million, or 6.8%, compared to $4.47 billion at September 30, 2024, primarily due to increases in noninterest bearing deposits of $35.9 million, $46.3 million in savings, $72.5 million in NOW accounts, $70.7 million in money market accounts, and $77.9 million in time deposits. The overall increase in deposits was primarily due to the acquisition of FRME’s five Illinois branches. Average deposits for the quarter to date ending December 31, 2024 increased $114.3 million compared to September 30, 2024. Total quarterly average deposits for the year over year period increased $22.0 million, or 0.5%, driven by an increase in average time deposits of $194.5 million, and NOW and money markets combined of $39.4 million, partially offset by decreases in our average demand deposits of $126.2 million, and savings accounts of $85.8 million. The bulk of the increase in total deposits in the fourth quarter of 2024 occurred in December, driven primarily by the acquisition of the FRME branches.

Borrowings

As of December 31, 2024, we had $20.0 million in other short-term borrowings due to short-term FHLB advances, compared to $335.0 million as of September 30, 2024, and $405.0 million as of December 31, 2023. The large decrease in short-term FHLB advances at December 31, 2024 is due to an influx of cash resulting from the acquisition of the five FRME branches on December 6, 2024, which allowed us to utilize the purchased deposits for lower cost funding.

Non-GAAP Presentations

Management has disclosed in this earnings release certain non-GAAP financial measures to evaluate and measure our performance, including the presentation of adjusted net income, net interest income and net interest margin on a fully taxable equivalent basis, and our efficiency ratio calculations on a taxable equivalent basis. The net interest margin fully taxable equivalent is calculated by dividing net interest income on a tax equivalent basis by average earning assets for the period.  Consistent with industry practice, management has disclosed the efficiency ratio including and excluding certain items, which is discussed in the noninterest expense presentation on page 7.

We consider the use of select non-GAAP financial measures and ratios to be useful for financial and operational decision making and useful in evaluating period-to-period comparisons.  We believe that these non-GAAP financial measures provide meaningful supplemental information regarding our performance by excluding certain expenditures or assets that we believe are not indicative of our primary business operating results or by presenting certain metrics on a fully taxable equivalent basis.  We believe these measures provide investors with information regarding balance sheet profitability, and we believe that management and investors benefit from referring to these non-GAAP financial measures in assessing our performance and when planning, forecasting, analyzing, and comparing past, present and future periods.

These non-GAAP financial measures should not be considered as a substitute for GAAP financial measures, and we strongly encourage investors to review the GAAP financial measures included in this earnings release and not to place undue reliance upon any single financial measure. In addition, because non-GAAP financial measures are not standardized, it may not be possible to compare the non-GAAP financial measures presented in this earnings release with other companies’ non-GAAP financial measures having the same or similar names. The tables beginning on page 17 provide a reconciliation of each non-GAAP financial measure to the most comparable GAAP equivalent.
