Old Second Bancorp, Inc. Reports First Quarter 2025 Net Income of $19.8 Million,

or $0.43 per Diluted Share

AURORA, IL, April 23, 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 first quarter of 2025. Our net income was $19.8 million, or $0.43 per diluted share, for the first quarter of 2025, compared to net income of $19.1 million, or $0.42 per diluted share, for the fourth quarter of 2024, and net income of $21.3 million, or $0.47 per diluted share, for the first quarter of 2024. Adjusted net income, a non-GAAP financial measure that excludes certain nonrecurring items, as applicable, was $20.6 million, or $0.45 per diluted share, for the first quarter of 2025, compared to $20.0 million, or $0.44 per diluted share, for the fourth quarter of 2024, and $21.2 million, or $0.47 per diluted share, for the first quarter of 2024. The pre-tax adjusting items impacting the first quarter of 2025 included the exclusion of $570,000 of mortgage servicing rights (“MSRs”) mark to market losses, and $454,000 of transaction-related expenses primarily from the First Merchants Bank (“FRME”) branch purchase in December 2024 as well as the pending merger with Bancorp Financial, Inc. (“Bancorp Financial”) that was announced in late February 2025. The adjusting items impacting the fourth quarter of 2024 included the exclusion of $385,000 of MSRs mark to market gains and $1.5 million of transaction-related expenses due to the FRME branch purchase. The adjusting item impacting the first quarter of 2024 included the exclusion of $94,000 of MSRs mark to market gains. 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 increased $720,000 in the first quarter of 2025 compared to the fourth quarter of 2024. The increase was primarily due to a $1.1 million decrease in provision for credit losses, as well as a $3.0 million decrease in interest expense in the first quarter of 2025, compared to the prior linked quarter. These increases to the current quarter’s net income were partially offset by a $1.7 million decrease in interest and dividend income and a $1.4 million decrease in noninterest income. Net income decreased $1.5 million in the first quarter of 2025 compared to the first quarter of 2024, primarily due to an increase of $6.3 million in noninterest expense, partially offset by a $3.1 million increase in net interest and dividend income, a $1.1 million decrease in provision for credit losses, and a $861,000 decrease in provision for income taxes.

²Both the Company and the Bank ratios are inclusive of a capital conservation buffer of 2.50%, and both are subject to the minimum capital adequacy guidelines of 7.00%, 8.50%, 10.50%, and 4.00% for the Common equity tier 1, Tier 1 risk-based, Total risk-based and Tier 1 leverage ratios, respectively.

Chairman, President and Chief Executive Officer Jim Eccher said “Old Second reported strong results in the first quarter of 2025 led by exceptional margin performance and disciplined operating efficiency. Tangible book value per share increased by more than 15% on both a linked quarter annualized and year over year basis despite the dilution associated with a branch purchase transaction in the fourth quarter of 2024. Nonperforming assets and classified loans have declined meaningfully on both year over year and linked quarter basis as well. First quarter return on average assets and return on average tangible common equity were 1.42% and 14.70%, respectively, the tax equivalent net interest margin was expanded meaningfully to 4.88% and the efficiency ratio was a very healthy 56.46%. This strong bottom-line performance and a well-positioned balance sheet drove an increase in the tangible common equity capital ratio to 10.34% from 9.04% for the prior year like period. We are exceptionally proud of our performance from both a bottom line perspective and in positioning ourselves to deliver value to our stockholders over the remainder of the year.”

“In February, we announced an agreement to acquire Evergreen Bank Group, a $1.5 billion bank holding company headquartered in Oak Brook, Illinois. We believe the transaction will add meaningful consumer lending capabilities and enhance the flexibility and profitability of Old Second’s balance sheet. Darin Campbell and his team have built an exceptional business that will diversify our revenue streams, enhance our management depth and provide a continuing opportunity to drive long-term stockholder value. Most importantly, we believe it strengthens our competitive position in Chicago and represents a step forward in our efforts to build the best bank possible for our customers and communities.”

Asset Quality & Earning Assets

●

Nonperforming loans, comprised of nonaccrual loans plus loans past due 90 days or more and still accruing, totaled $34.8 million at March 31, 2025, $30.3 million at December 31, 2024, and $65.1 million at March 31, 2024. Nonperforming loans, as a percent of total loans, were 0.9% at March 31, 2025, 0.8% at December 31, 2024, and 1.6% at March 31, 2024. The increase in the first quarter of 2025 for nonperforming loans is driven by nonaccrual loans inflows of $11.6 million, primarily driven by two larger commercial relationships, partially offset by $7.1 million of nonaccrual outflows. Nonaccrual loan outflows consist of $1.7 million paid off, $1.5 million of fully charged off loans, and $3.9 million of partial principal reductions from payments and partial charge-offs.

●

Total loans were $3.94 billion at March 31, 2025, reflecting a decrease of $41.1 million compared to December 31, 2024, and a decrease of $29.2 million compared to March 31, 2024. The decrease from the prior quarter end as well as 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 first quarter of 2025 totaled $3.96 billion, reflecting a decrease of $44.0 million from the fourth quarter of 2024, and a decrease of $60.3 million from the first quarter of 2024.

●

Available-for-sale securities totaled $1.15 billion at March 31, 2025, compared to $1.16 billion at December 31, 2024 and $1.17 billion at March 31, 2024. The unrealized mark to market loss on securities totaled $59.7 million as of March 31, 2025, compared to $68.6 million as of December 31, 2024, and $85.0 million as of March 31, 2024, due to market interest rate fluctuations as well as changes year over year in the composition of the securities portfolio. During the quarter ended March 31, 2025, we had security purchases of $82.9 million, and security maturities, calls and paydowns of $106.3 million, compared to security purchases of $84.9 million and security maturities, calls and paydowns of $101.2 million during the quarter ended December 31, 2024. During the quarter ended March 31, 2024, we had security purchases of $15.7 million, $32.7 million of maturities and paydowns, and sales of $5.3 million, which resulted in net realized gains of $1,000. 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 2025 and 2024. 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 TE basis, which is a non-GAAP financial measure as discussed in the table on page 17, and includes loan fee income of $545,000 for the first quarter of 2025, loan fee income of $140,000 for the fourth quarter of 2024, and loan fee expense of $867,000 for the first quarter of 2024. Nonaccrual loans are included in the above stated average balances.

The decreased yield of two basis points on interest earning assets compared to the linked period was primarily driven by repricing within the loan portfolio and, to a lesser extent, a reduction in correspondent bank account yields which was partially offset by higher volumes. 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.

The year over year increase of nine 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 $1.6 million in the first quarter of 2025 compared to the prior year like quarter, while the tax equivalent yield on the securities available for sale portfolio increased 41 basis points year over year primarily due to variable security rate resets. Average balances of loans and loans held for sale decreased $60.3 million in the first quarter of 2025 compared to the prior year like quarter, while the tax equivalent yield on loans and loans held for sale increased four basis points.

Average balances of interest bearing deposit accounts have increased steadily since the fourth quarter of 2024 through the first quarter of 2025, from $2.89 billion to $3.10 billion, as NOW, money market, savings, and time account average balances all increased. We have continued to control the cost of funds over the periods reflected by monitoring market activity as well as allowing previous exception-priced deposits to runoff naturally, which resulted in a 13 basis point reduction in the cost of interest bearing deposits, from 141 basis points for the quarter ended December 31, 2024, to 128 basis points for the quarter ended March 31, 2025. A 52 basis point decrease in the cost of time deposits for the quarter ended March 31, 2025 drove a significant portion of the overall decrease from the prior linked quarter. The cost of interest bearing deposits increased ten basis points for the quarter ended March 31, 2025 from 118 basis points for the quarter ended March 31, 2024. A 22 basis point increase in the cost of money market accounts drove a significant portion of the overall increase from the prior year like quarter.

Borrowing costs decreased in the first quarter of 2025, compared to the fourth quarter of 2024, primarily due to the $203.3 million decrease in average other short-term borrowings stemming from a decrease in average daily FHLB advances over the prior linked quarter as the remainder of this borrowing was paid down in the first quarter of 2025. The decrease of $330.8 million year over year of average FHLB advances was based on daily liquidity needs and was the primary driver of the $4.5 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, showed steady growth over the periods presented above. Our net interest margin (GAAP) increased 19 basis points to 4.85% for the first quarter of 2025, compared to 4.66% for the fourth quarter of 2024, and increased 30 basis points compared to 4.55% for the first quarter of 2024. Our net interest margin (TE) increased 20 basis points to 4.88% for the first quarter of 2025, compared to 4.68% for the fourth quarter of 2024, and increased 30 basis points compared to 4.58% for the first quarter of 2024. The increase in net interest margin for the first quarter of 2025, compared to the prior linked quarter, was driven by market interest rates as well as the impact of a full quarter of average deposit balances stemming from the acquired FRME branches, which drove down our cost of funds. 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 first quarter of 2025, 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 decreased $1.4 million, or 12.1%, in the first quarter of 2025, compared to the fourth quarter of 2024, and decreased $300,000, or 2.9%, compared to the first quarter of 2024. The decrease from the fourth quarter of 2024 was primarily driven by a $1.0 million decrease in residential mortgage banking revenue due to a decrease of $955,000 in MSRs mark to market valuation. Also contributing to the decrease during the quarter was a $210,000 decrease in wealth management income primarily due to a decline in estate fees, and a $269,000 decrease in the cash surrender value of BOLI due to market interest rates.

The decrease in noninterest income of $300,000 in the first quarter of 2025, compared to the first quarter of 2024, is primarily due to a $499,000 decrease in residential mortgage banking revenue mainly due to a $664,000 decrease in MSRs mark to market valuations driven by increased prepayment speeds during the first quarter compared to the prior quarter. Also contributing to the reduction in noninterest income during the quarter was a $674,000 decrease in the cash surrender value of BOLI from the like period in 2024 due to market interest changes. Partially offsetting the decrease in noninterest income from the prior year like quarter was a $528,000 increase in wealth management income primarily due to growth in advisory fees and estate fees and a $304,000 increase in service charges on deposits.

¹The 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, net of gain or loss on branch sales, divided by the sum of net interest income on a fully TE basis, total noninterest income less net gains or losses on securities, 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 18 that provides a reconciliation of this non-GAAP financial measure to the most comparable GAAP equivalent.

Noninterest expense for the first quarter of 2025 increased $183,000, or 0.4%, compared to the fourth quarter of 2024, and increased $6.3 million, or 16.4%, compared to the first quarter of 2024. The increase in the first quarter of 2025, compared to the fourth quarter of 2024, was attributable to a $1.4 million increase in salaries and employee benefits, with increases reflected primarily in restricted stock expense, payroll taxes, and increases in salaries based on increased base salary rates. Also contributing to the increase in noninterest expense in the first quarter of 2025 was a $321,000 increase in the amortization of core deposit intangible due to the FRME branch purchase in December 2024. Partially offsetting the increase over the prior linked quarter was a $311,000 decrease in computer and data processing, a $457,000 decrease in consulting & management fees, and a $363,000 decrease in other expenses, which were all due to FRME acquisition-related costs recorded in the fourth quarter of 2024.

The year over year increase in noninterest expense is primarily attributable to a $2.7 million increase in salaries and employee benefits, primarily due to increases in annual base salary rates, officers’ incentives, and restricted stock expense in the first quarter of 2025. Also contributing to the increase was a $621,000 increase in occupancy, furniture and equipment, a $457,000 increase in core deposit intangible, and a $246,000 increase in legal fees primarily due to transaction-related costs incurred related to the FRME branches purchased in December 2024 as well as growth in legal costs related to our pending acquisition of Bancorp Financial. Other increases year over year include a $1.8 million increase in other real estate owned expense, net, as the first quarter of 2025 included a $236,000 loss on the sale of an OREO property compared to no net gain or loss in the first quarter of 2024, a $454,000 increase in OREO valuation reserve expense based on valuation write downs on two of our OREO properties in the first quarter of 2025, and a $1.1 million increase in other OREO expenses due to the operations and subsequent sales of two OREO properties and the associated closing costs in the first quarter of 2025.

Total loans decreased by $41.1 million at March 31, 2025, compared to December 31, 2024, and decreased $29.2 million for the year over year period. The decrease in total loans in the first quarter of 2025 compared to the prior linked quarter was due to increased paydowns, net of originations, over the first quarter, primarily in commercial, commercial real estate-owner occupied, and multifamily loans. The year over year reduction in loans is primarily due to paydowns, net of originations, in commercial real estate – owner occupied of $112.6 million, commercial of $63.7 million, multifamily of $46.2 million, partially offset by lease originations, net of paydowns, of $79.8 million, commercial real estate – investor loan growth of $87.1 million and construction loan growth of $36.7 million. Increases were noted in the leases segment in the first quarter of 2025 compared to the prior linked quarter and compared to the prior year like period primarily due to continued expansion of this product line over the past year.

Our securities available-for-sale portfolio totaled $1.15 billion as of March 31, 2025, reflecting a decrease of $15.0 million from December 31, 2024, and a decrease of $22.1 million since March 31, 2024. The portfolio’s decrease in the first quarter of 2025, compared to the prior quarter-end, was due to $106.3 million in maturities, calls, and paydowns, partially offset by $82.9 million in purchases and an $8.9 million reduction in unrealized losses. Net unrealized losses at March 31, 2025 were $59.7 million, compared to $68.6 million at December 31, 2024 and $85.0 million at March 31, 2024. 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.

¹Repossessed assets are reported in other assets.

Nonperforming loans consist of nonaccrual loans and loans 90 days or more past due and still accruing interest. Purchased credit-deteriorated (“PCD”) loans acquired in our acquisitions of West Suburban and ABC Bank totaled $10.6 million, net of purchase accounting adjustments, at March 31, 2025. No PCD loans were acquired with our FRME branch acquisition. PCD loans that meet the definition of nonperforming loans are included in our nonperforming disclosures. Nonperforming loans to total loans was 0.9% as of March 31, 2025, 0.8% as of December 31, 2024, and 1.6% as of March 31, 2024.

Classified loans as of March 31, 2025 decreased by $7.0 million from December 31, 2024, and decreased by $50.4 million from March 31, 2024. The net decrease from the fourth quarter of 2024 was primarily driven by outflows of $1.7 million of paid off loans, $481,000 of loans upgraded, $4.4 million of principal reductions from payments and partial charge-offs, and $1.5 million full loan charge-offs. The decrease in classified loans in the first quarter of 2025 was partially offset by additions of $1.1 million on twelve loans. 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 March 31, 2025, our allowance for credit losses (“ACL”) on loans totaled $41.6 million, and our ACL on unfunded commitments, included in other liabilities, totaled $2.0 million. In the first quarter of 2025, we recorded provision expense of $2.4 million based on historical loss rate updates, our assessment of nonperforming loan metrics and trends, as well as estimated future credit losses. The first quarter of 2025 provision expense consisted of a $2.3 million provision for credit losses on loans, and a $115,000 provision for credit losses on unfunded commitments. The increase 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 $4.4 million in the first quarter of 2025, primarily within the commercial portfolio. The fourth quarter 2024 provision expense of $3.5 million consisted of a $4.1 million provision for credit losses on loans, and $600,000 reversal of provision for credit losses on unfunded commitments. We recorded net charge-offs of $4.9 million in the fourth quarter of 2024. In the first quarter of 2024, we recorded a provision expense of $3.5 million, which consisted of a $3.5 million provision for credit losses on loans and a $44,000 reversal of provision for credit losses on unfunded commitments. We recorded net charge-offs of $3.7 million in the first quarter of 2024. Our ACL on loans to total loans was 1.1% as of March 31, 2025, December 31, 2024, and March 31, 2024.

The ACL on unfunded commitments totaled $2.0 million as of March 31, 2025, $1.9 million as of December 31, 2024, and $2.7 million as of March 31, 2024.

²Represents the percentage of net charge-offs attributable to each category of loans.

Gross charge-offs for the first quarter of 2025 were $4.5 million, compared to $8.9 million for the fourth quarter of 2024 and $4.0 million for the first quarter of 2024. Gross recoveries were $176,000 for the first quarter of 2025, compared to $4.1 million for the fourth quarter of 2024, and $293,000 for the first quarter of 2024. Continued recoveries are indicative of the ongoing aggressive efforts by management to effectively manage and resolve prior charge-offs, however, recoveries cannot be forecasted or expected at the same pace in the future.

Deposits

Total deposits were $4.85 billion at March 31, 2025, an increase of $84.1 million, or 1.8%, compared to $4.77 billion at December 31, 2024, primarily due to increases in noninterest bearing deposits of $8.8 million, savings of $20.4 million, NOW accounts of $31.0 million, and money market accounts of $68.0 million. These increases were partially offset by a decline in time deposits of $44.1 million. Total quarterly average deposits for the year over year period increased $218.7 million, or 4.8%, driven by an increase in average time deposits of $166.9 million, and NOW and money markets combined of $185.7 million, partially offset by decreases in our average demand deposits of $116.1 million, and savings accounts of $17.8 million. The overall increase in quarterly average deposits for the year over year period was primarily due to the acquisition of FRME branches in December 2024. During the first quarter of 2025, we have seen run-off of FRME time deposits offset by seasonal increases in our legacy portfolio.

Borrowings

As of March 31, 2025, we had no other short-term borrowings, compared to $20.0 million as of December 31, 2024, and $220.0 million as of March 31, 2024, all of which are short-term FHLB advances. The large decrease in short-term FHLB advances 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.
