Earnings headlines have often been followed by modest moves, with one notable selloff on a strong quarter; most non-earnings news drew small positive reactions.

Recent Company History

Over the last six months, Old Second Bancorp has combined steady earnings with balance sheet growth and acquisition activity. Q2 and Q3 2025 earnings showed solid core performance but mixed market reactions, while Q4 2024 results reflected higher credit costs. Integration of Evergreen Bank Group on Oct 20, 2025 and sponsor finance deals supported growth and diversification. Today’s Q4 2025 earnings, with higher net income and adjusted net income, build on this acquisition-driven expansion trend.

Balance sheet growth, tangible equity gains and asset quality metrics provide important context. Investors should focus on future trends in credit provisions, noninterest expense, and loan growth, as well as how consistently Old Second maintains returns and capital ratios at or above the levels disclosed for this quarter.

Key Terms

7 terms

non-gaap financial

"Adjusted net income, a non-GAAP financial measure that excludes certain..."

Non-GAAP refers to financial measures that companies use to show their earnings or performance without including certain expenses or income that are often added back to give a different picture. It matters because it can make a company's results look better or more favorable, but it may also hide important costs, so investors need to look at both GAAP (official rules) and non-GAAP numbers to get a full understanding.

mortgage servicing rights financial

"included the exclusion of $428,000 of mortgage servicing rights ("MSRs")..."

Mortgage servicing rights are the contractual right to collect mortgage payments, manage escrow accounts, handle customer service and delinquency actions on a pool of home loans, in exchange for a portion of the loan’s payments. They matter to investors because their value behaves like a revenue stream that can rise or fall with interest rates and borrower behavior — similar to owning a toll bridge where income depends on traffic volume and maintenance costs — and thus affect a lender’s earnings and risk profile.

mark to market financial

"mortgage servicing rights ("MSRs") mark to market losses, and $2.3 million..."

Mark to market is an accounting practice that records the value of an asset or liability at its current market price instead of its original purchase cost. For investors, it means a company's reported earnings, balance sheet and capital ratios change as market prices move—like updating a price tag each day—so reported profits and risk can fluctuate quickly with market swings.

net interest margin financial

"The tax equivalent net interest margin has remained resilient and impressive at 5.09%..."

Net interest margin measures how much a bank earns from lending and investing compared with what it pays for funding, expressed as a percentage of its interest-earning assets. Think of it like a grocery store’s markup: it shows the gap between buying cost and selling price per dollar of goods — here, the cost is interest paid and the sale is interest received. Investors watch it because a higher margin usually means a bank is more profitable and better at managing interest rate and credit conditions.

efficiency ratio financial

"and the adjusted efficiency ratio was a very healthy 51.28%."

A measure of how much a company spends to produce each dollar of revenue, usually shown as operating expenses divided by revenue and expressed as a percentage. Think of it as a household’s budget: a lower percentage means more of each dollar earned stays as profit, while a higher number means costs are eating into returns. Investors use it to judge cost control and compare how efficiently companies turn revenue into earnings, especially in banks and financial firms.

tangible common equity financial

"tangible common equity capital ratio to 11.02% from 10.04% last year end..."

Tangible common equity is the portion of a company’s net worth that belongs to ordinary shareholders after removing intangible items (like goodwill or patents) and any preferred claims; it’s often expressed on a per-share basis. Think of it as the hard, sellable value left for common owners if you removed non-physical assets and paid off debts—investors use it to judge how much real cushion a company has and whether the stock might be under- or over-valued.

tier 1 risk-based capital ratio regulatory

"Tier 1 risk-based capital ratio | | 13.41 | | 12.85 | | 13.34"

A Tier 1 risk-based capital ratio measures a bank’s core financial cushion—its highest-quality capital such as common equity—relative to the size and risk of its assets, where riskier loans count for more. Think of it as the safety margin a bank keeps against losses compared to the amount and riskiness of what it owns; investors use it to judge a bank’s solvency, regulatory strength, and ability to withstand shocks or sustain payouts.

AURORA, IL / ACCESS Newswire / January 21, 2026 / 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 2025. Our net income was $28.8 million, or $0.54 per diluted share, for the fourth quarter of 2025, compared to net income of $9.9 million, or $0.18 per diluted share, for the third quarter of 2025, and net income of $19.1 million, or $0.42 per diluted share, for the fourth quarter of 2024.

Adjusted net income, a non-GAAP financial measure that excludes certain nonrecurring items, as applicable, was $30.8 million, or $0.58 per diluted share, for the fourth quarter of 2025, compared to $28.4 million, or $0.53 per diluted share, for the third quarter of 2025, and $20.0 million, or $0.44 per diluted share, for the fourth quarter of 2024. The pre-tax adjusting items impacting the fourth quarter of 2025 included the exclusion of $428,000 of mortgage servicing rights ("MSRs") mark to market losses, and $2.3 million of transaction-related expenses, net of gains on branch sales, primarily from our acquisition of Bancorp Financial, Inc ("Bancorp Financial"). The adjusting items impacting the third quarter of 2025 included the exclusion of $13.2 million of day two provision for credit losses recorded with our acquisition of Bancorp Financial, $389,000 of MSRs mark to market losses, $430,000 of death benefits realized on BOLI, and $11.5 million of transaction-related expenses, net of gains on branch sales, primarily from our acquisition of Bancorp Financial. 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, net of losses on branch sales, primarily from our purchase of five branches from First Merchants Bank ("FRME"). See the discussion entitled "Non-GAAP Presentations" below and the tables beginning on page 18 found at www.oldsecond.com under the Investor Relations page, that provide a reconciliation of each non-GAAP measure to the most comparable GAAP equivalent.

Net income increased $18.9 million in the fourth quarter of 2025 compared to the third quarter of 2025 driven by lower acquisition related costs. The increase was primarily due to a $16.7 million decrease in provision for credit losses, as $3.0 million of provision expense was recorded in the fourth quarter of 2025, compared to $13.2 million of a day two provision from our acquisition of Bancorp Financial and $6.5 million of provision expense in the prior linked quarter. In addition, there was a $2.0 million decrease in interest expense driven by the decrease in interest paid on deposits, and a $10.2 million decrease in noninterest expense in the fourth quarter of 2025, compared to the prior linked quarter, mainly due to the timing of costs incurred related to our acquisition of Bancorp Financial. The increases to the fourth quarter of 2025's net income, as compared to the prior quarter, were partially offset by a $1.8 million decrease in interest and dividend income, primarily due to declines in rates and volume on securities coupled with a decline on yields, partially offset by an increase in volume in the loan portfolio, a $955,000 decrease in noninterest income, and a $7.3 million increase in provision for income taxes. Net income increased $9.7 million in the fourth quarter of 2025 compared to the fourth quarter of 2024, primarily due to an increase of $27.0 million in interest and dividend income stemming from our acquisition of Bancorp Financial. The increase in net income compared to the prior year like quarter was partially offset by a $5.6 million increase in interest expense and an $8.6 million increase in noninterest expense, both of which were driven by the Bancorp Financial acquisition, as well as a $4.2 million increase in provision for income taxes due to higher pretax income.

Operating Results

• Fourth quarter 2025 net income was $28.8 million, reflecting an $18.9 million increase from the third quarter of 2025, and an increase of $9.7 million from the fourth quarter of 2024.

Chairman, President and Chief Executive Officer Jim Eccher said "Old Second concluded a great year with an extremely strong fourth quarter. Core earnings have exhibited very strong growth in recent periods and profitability remains among the best in the industry with return on average assets of 1.75% and return on average tangible equity of 17.23%, both excluding acquisition related purchase accounting and deal costs. The tax equivalent net interest margin has remained resilient and impressive at 5.09% and the adjusted efficiency ratio was a very healthy 51.28%. This strong bottom-line performance and a well-positioned balance sheet drove an increase in the tangible common equity capital ratio to 11.02% from 10.04% last year end and tangible book value per share increased by 14% in 2025 despite the dilution associated with a meaningful acquisition."

"In summary, we are proud of the strength and sustainability of our performance, and with marginal spreads in loan and deposit markets improving, we are excited about the opportunities for additional growth in 2026. We believe we have exceptional balance sheet flexibility and the strategic positioning to capitalize on growth opportunities that may come our way in the near future. I would like to thank our team for their hard work and execution in 2025, including integrations and systems conversions and upgrades that have made us a much better Old Second. I could not be more excited about the things we can accomplish within the next year."

Asset Quality & Earning Assets

• Nonperforming loans, comprised of nonaccrual loans plus loans past due 90 days or more and still accruing, totaled $52.8 million at December 31, 2025, $48.0 million at September 30, 2025, and $30.3 million at December 31, 2024. Nonperforming loans, as a percent of total loans, was 1.0% at December 31, 2025, 0.9% at September 30, 2025, and 0.8% at December 31, 2024. The $4.8 million increase in the fourth quarter of 2025 for nonperforming loans is driven by a $13.8 million increase in nonaccrual loans due to inflows of $18.3 million, primarily related to two commercial real estate relationships totaling $14.9 million, partially offset by outflows of $4.5 million, which include $2.4 million of loans paid off and $2.1 million of partial principal reductions from payments and partial charge-offs on loans. The increase to nonaccrual loans was partially offset by a $9.0 million decrease to loans past due 90 days or more and still accruing, primarily comprised of two legacy relationships, one that was paid off in the fourth quarter of 2025 and another that was downgraded to nonaccrual.

• Total loans were $5.25 billion at December 31, 2025, reflecting a decrease of $12.4 million compared to September 30, 2025 and an increase of $1.27 billion compared to December 31, 2024. The significant increase from December 31, 2024 is primarily driven by the $1.19 billion of loans acquired in our acquisition of Bancorp Financial. The decline in loans from September 30, 2025 is influenced by the seasonal reductions within the powersport portfolio. Based on historical data, the powersport portfolio shows much higher origination volume from March through September as compared to the remainder of the year. Excluding loans purchased from the Bancorp Financial acquisition, organic loan growth, net of paydowns, totaled $76.1 million, or 1.9%, compared to December 31, 2024 total loans. Average loans (including loans held-for-sale) for the fourth quarter of 2025 totaled $5.28 billion, reflecting an increase of $61.3 million from the third quarter of 2025, and an increase of $1.28 billion from the fourth quarter of 2024.

• Available-for-sale securities totaled $1.09 billion at December 31, 2025, compared to $1.16 billion at September 30, 2025 and $1.16 billion at December 31, 2024. The unrealized mark to market loss on securities totaled $43.1 million as of December 31, 2025, compared to $47.7 million as of September 30, 2025, and $68.6 million as of December 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 December 31, 2025, we had security purchases of $7.8 million and security maturities, calls and paydowns of $78.9 million, compared to security purchases of $20.6 million, security sales of $7.5 million, excluding the sale of Bancorp Financial's $117.6 million available-for-sale securities portfolio after the acquisition closed, and security maturities, calls and paydowns of $41.1 million during the quarter ended September 30, 2025. During the quarter ended December 31, 2024, we had security purchases of $84.9 million and $101.2 million of maturities, calls, and paydowns. We may continue to buy and sell strategically identified securities as opportunities arise.

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 8 found at www.oldsecond.com, under the Investor Relations page.

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 18 found at www.oldsecond.com, under the Investor Relations page, provide a reconciliation of each non-GAAP financial measure to the most comparable GAAP equivalent.
