Old Second Bancorp, Inc. Reports Third Quarter 2023 Net Income of $24.3 Million,

or $0.54 per Diluted Share

AURORA, IL, October 18, 2023 – 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 third quarter of 2023.  Our net income was $24.3 million, or $0.54 per diluted share, for the third quarter of 2023, compared to net income of $25.6 million, or $0.56 per diluted share, for the second quarter of 2023, and net income of $19.5 million, or $0.43 per diluted share, for the third quarter of 2022. Adjusted net income, a non-GAAP financial measure that excludes Visa portfolio and land trust portfolio gains on sale, Visa portfolio liquidation and deconversion costs, and any merger related costs, as applicable, was $24.8 million, or $0.55 per diluted share, for the third quarter of 2023, compared to $25.6 million, or $0.56 per diluted share, for the second quarter of 2023, and $19.6 million, or $0.43 per diluted share, for the third quarter of 2022.  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 $1.2 million in the third quarter of 2023 compared to the second quarter of 2023. The decrease was primarily due to the increase of $1.0 million in provision for credit losses, and an increase in noninterest expense of $2.6 million in the third quarter of 2023, which were partially offset by a $1.7 million increase in noninterest income and a $1.3 million decrease in provision for income taxes. Net income increased $4.8 million in the third quarter of 2023 compared to the third quarter of 2022, primarily due to an increase in net interest income of $7.5 million year over year due to rising market interest rates and a $1.5 million decrease in provision for credit losses. The increase in net income in the third quarter of 2023 was partially offset by a $1.6 million decrease in noninterest income and a $1.4 million increase in noninterest expense.  The third quarter of 2023 was impacted by a pre-tax net loss on the sale of securities of $924,000, compared to pre-tax net losses on the sale of securities of $1.5 million and $1,000 in the second quarter of 2023 and the third quarter of 2022, respectively.  In addition, the third quarter of 2023 was also impacted by $629,000 of deconversion and liquidation costs from the 2022 sale of our Visa credit card portfolio.

Operating Results

Third quarter 2023 net income was $24.3 million, reflecting a $1.2 million decrease from the second quarter 2023, and an increase of $4.8 million from the third quarter of 2022.  Adjusted net income, as defined above, was $24.8 million for the third quarter of 2023, a decrease of $776,000 from adjusted net income for the second quarter of 2023, and an increase of $5.2 million from adjusted net income for the third quarter of 2022.
Net interest and dividend income was $63.0 million for the third quarter of 2023, reflecting a decrease of $550,000, or 0.9%, from the second quarter of 2023, and an increase of $7.5 million, or 13.4%, from the third quarter of 2022.
--- ---
We recorded a net provision for credit losses of $3.0 million in the third quarter of 2023, compared to a net provision for credit losses of $2.0 million in the second quarter of 2023, and a net provision for credit losses of $4.5 million in the third quarter of 2022.
--- ---
Noninterest income was $9.9 million for the third quarter of 2023, an increase of $1.7 million, or 20.1%, compared to $8.2 million for the second quarter of 2023, and a decrease of $1.6 million, or 14.1%, compared to $11.5 million for the third quarter of 2022.

Noninterest expense was $37.4 million for the third quarter of 2023, an increase of $2.6 million, or 7.4% compared to $34.8 million for the second quarter of 2023, and an increase of $1.4 million, or 4.0%, compared to $36.0 million for the third quarter of 2022.
We had a provision for income tax of $8.1 million for the third quarter of 2023, compared to a provision for income tax of $9.4 million for the second quarter of 2023 and a provision of $7.1 million for the third quarter of 2022. The effective tax rate for each of the periods presented was 25.1%, 26.9%, and 26.5%, respectively.
--- ---
On October 17, 2023, our Board of Directors declared a cash dividend of $0.05 per share payable on November 6, 2023, to stockholders of record as of October 27, 2023.

Chairman, President and Chief Executive Officer Jim Eccher said “Old Second reported strong results in the third quarter as we earned $24.3 million in net income, ROAA of 1.67% and ROATCE of 22.80%.  Adjusting for merger related expenses, the gain on the land trust sale and Visa portfolio related items, our earnings per share increased by 28% over the third quarter 2022.  Our tangible book value per share has increased by more than 30% over the last year and capital ratios continue to build very quickly with our tangible common equity ratio increasing by 50 basis points on a linked quarter basis to 7.67%.  Our focus over the near term will continue to be on assessing risks both within the loan portfolio and more broadly and optimizing the earning asset mix while reducing our overall sensitivity to interest rates.  We believe the ability to deliver exceptional returns and compound book value, at a time when marginal spreads in deposit and lending markets are tight, illustrates the quality of the franchise we have built. With a strong balance sheet, low-cost granular funding and continuing excellent overall profitability, Old Second is well positioned for the remainder of 2023 and beyond.”

Asset Quality & Earning Assets

Nonperforming loans, comprised of nonaccrual loans plus loans past due 90 days or more and still accruing, and, prior to January 1, 2023, performing troubled debt restructurings, totaled $63.6 million at September 30, 2023, $61.2 million at June 30, 2023, and $52.9 million at September 30, 2022.  Nonperforming loans, as a percent of total loans, were 1.6% at September 30, 2023, 1.5% at June 30, 2023, and 1.4% at September 30, 2022.  The increase in the third quarter of 2023 is driven by the downgrade of a few credits during the quarter, due primarily to office-related loans within the commercial real estate-investor portfolio and debt service coverage shortfalls.
Total loans were $4.03 billion at September 30, 2023, reflecting an increase of $14.0 million compared to June 30, 2023, and an increase of $160.2 million compared to September 30, 2022. The increase year over year was largely driven by the growth in leases, commercial real estate-investor, construction, and multifamily portfolios.  Average loans (including loans held-for-sale) for the third quarter of 2023 totaled $4.01 billion, reflecting a decrease of $29.3 million from the second quarter of 2023 and an increase of $257.7 million from the third quarter of 2022.
--- ---
Available-for-sale securities totaled $1.23 billion at September 30, 2023, compared to $1.34 billion at June 30, 2023, and $1.61 billion at September 30, 2022.  The unrealized mark to market loss on securities totaled $120.5 million as of September 30, 2023, compared to $112.4 million as of June 30, 2023, and $131.0 million as of September 30, 2022, due to market interest rate fluctuations as well as changes year over year in the composition of the securities portfolio. During the quarter ended September 30, 2023, securities sales of $65.6 million resulted in net realized losses of $924,000, compared to sales of $74.0 million during the quarter ended June 30, 2023, which resulted in net realized losses of $1.5 million, and no security sales for the quarter ended September 30, 2022, with a loss of $1,000 on the call of securities.  We may continue to sell strategically identified securities as opportunities arise.

^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 expense of $780,000 for the third quarter of 2023, and loan fee expense of $242,000 and $588,000 for the second quarter of 2023 and the third quarter of 2022, respectively. Nonaccrual loans are included in the above stated average balances.

The increased yield of 10 basis points on interest earning assets compared to the linked period was driven by higher yields on loan originations than those in the previous period as well as repricing within the existing variable rate portfolios for securities available-for-sale and loans. 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 136 basis points on interest earning assets was driven by significant increases to benchmark interest rates as well as strong loan growth throughout the period, specifically within the leases, commercial real estate and multifamily portfolios, as these loan segments generally produce the greatest yield. The increases in 4

benchmark interest rates impacted yields on the securities portfolio through the inverse relationship between interest rates and market value coupled with maturities and strategic sales of lower yielding assets, as we work to increase the weighted average yield in the portfolio.

Average balances of interest bearing deposit accounts have decreased steadily since the third quarter of 2022 through the third quarter of 2023, from $3.23 billion to $2.79 billion, with decreases reflected in all deposit categories excluding time deposits. We have continued to control the cost of funds over the periods reflected, with the rate of overall interest bearing deposits increasing to 65 basis points for the quarter ended September 30, 2023, from 40 basis points for the quarter ended June 30, 2023, and from nine basis points for the quarter ended September 30, 2022. A 32 basis point increase in the cost of money market funds for the quarter ended September 30, 2023 compared to prior linked quarter, and a 91 basis point increase compared to the prior year like quarter were both due to select deposit account exception pricing, and drove a significant portion of the overall increase.  Average rates paid on time deposits for the quarter ended September 30, 2023 increased by 63 basis points and 140 basis points in the quarter over linked quarter and year over year quarters, respectively, primarily due to CD rate specials we offered.

Borrowing costs decreased in the third quarter of 2023, compared to the second quarter of 2023, primarily due to the redemption of the senior notes as of June 30, 2023, partially offset by an increase in average short-term borrowings of $24.6 million stemming from increased average FHLB advances over the prior quarter. The increase of $421.7 million year over year of average FHLB advances was based on daily liquidity needs. Subordinated and junior subordinated debt interest expense were essentially flat over each of the periods presented. Senior notes had the most significant interest expense decrease, as we had redeemed all of the $45.0 million senior notes, net of deferred issuance costs, in June 2023, resulting in senior notes having no balance after that time. In February 2023, we paid off the remaining balance of $9.0 million on the original $20.0 million term note issued in 2020, resulting in notes payable and other borrowings having no balance after that time.

Our net interest margin (GAAP) increased three basis points to 4.64% for the third quarter of 2023, compared to 4.61% for the second quarter of 2023, and increased 71 basis points compared to 3.93% for the third quarter of 2022.  Our net interest margin (TE) increased two basis points to 4.66% for the third quarter of 2023, compared to 4.64% for the second quarter of 2023, and increased 70 basis points compared to 3.96% for the third quarter of 2022.  The increase in the third quarter, compared to the prior quarter, is primarily due to the growth in interest income due to the rising interest rate environment, and a decrease in borrowing interest expense due to the redemption of the senior notes in June 2023. The increase in the third quarter, compared to the prior year like quarter, is primarily due to an increase in market interest rates, and the related rate resets on loans and securities during the past year, as well as continuing loan growth relative to a more modest increase in costs of interest bearing liabilities. 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.

The decrease in noninterest income of $1.6 million in the third quarter of 2023, compared to the third quarter of 2022, is primarily due to an increase in security losses, net, of $923,000 on strategic sales for the quarter ended September 30, 2023, a decrease of $267,000 on mortgage servicing rights mark to market gains, and a $1.1 million decrease in other income due to a $743,000 pretax gain on a Visa credit card portfolio sale and a $180,000 pretax gain on the sale of a land trust portfolio recorded in the third quarter of 2022. These decreases were partially offset by a $773,000 increase in the cash surrender value of BOLI due to market interest rate changes. 6

^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 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-related costs, net of gains on branch sales, Visa credit card portfolio liquidation and related deconversion costs, as well as any merger related costs, if applicable, divided by the sum of net interest income on a fully tax equivalent basis, total noninterest income less net gains or losses on securities, mark to market gains or losses on MSRs, gain on the sale of our Visa credit card and land trust portfolios, 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 third quarter of 2023 increased $2.6 million, or 7.4%, compared to the second quarter of 2023, and increased $1.4 million, or 4.0%, compared to the third quarter of 2022.  The increase in the third quarter of 2023 compared to the second quarter of 2023 was attributable to a $1.3 million increase in salaries and employee benefits, primarily due to an increase in salaries and the officer incentive accrual.  Also contributing to the increase in the third quarter of 2023 was a $632,000 increase in computer and data processing costs as the second quarter reflects software contract incentives, and a $787,000 increase in other expenses primarily due to $629,000 of liquidation costs recorded from the September 2023 Visa credit card portfolio deconversion, which we sold in the third quarter of 2022 and continued to service through the third quarter of 2023.  Partially offsetting the increase in noninterest expense in the third quarter of 2023 was a $186,000 decrease in legal fees, as the second quarter of 2023 experienced higher legal costs due to senior debt redemption, the proxy filing, and benefit plan reviews.

The year over year increase in noninterest expense is primarily attributable to a $2.1 million increase in salaries and employee benefits, primarily due to an increase in salaries due to higher wage rates in the current year. Also contributing to the increase was a $765,000 increase in other expense, which was primarily due to $629,000 of liquidation and deconversion costs recorded on the Visa credit card portfolio liquidation in the third quarter of 2023. Partially offsetting the increase in noninterest expense in the third quarter of 2023, compared to the third quarter of 2022, was a $613,000 decrease in furniture and equipment expenses, a $621,000 decrease in computer and data processing expenses, and a $115,000 decrease in legal fees, all stemming from acquisition related costs that were recorded in the third quarter of 2022. 7

The portfolio decrease of $106.0 million in the third quarter of 2023, compared to the prior quarter-end, was due to security sales of $65.6 million, which resulted in a net realized loss of $924,000, as well as paydowns of $29.6 million.  Net unrealized losses at September 30, 2023 were $120.5 million, compared to $112.4 million at June 30, 2023 and $131.0 million at September 30, 2022. 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 sales 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. 8

^1^As of January 1, 2023, the Company prospectively adopted ASU 2022-02, Topic 326 “Troubled Debt Restructurings (“TDRs”) and Vintage Disclosures”, which eliminated the need for recognition, measurement and disclosure of TDRs going forward.

Nonperforming loans consist of nonaccrual loans and loans 90 days or more past due and still accruing interest.  Prior to January 1, 2023, nonperforming loans also included performing troubled debt restructured loans accruing interest.  Purchased credit-deteriorated (“PCD”) loans acquired in our acquisitions of West Suburban and ABC Bank totaled $61.2 million, net of purchase accounting adjustments, at September 30, 2023.  PCD loans that meet the definition of nonperforming loans are included in our nonperforming disclosures.  Nonperforming loans to total loans was 1.6% as of September 30, 2023, 1.5% as of June 30, 2023, and 1.4% as of September 30, 2022. Nonperforming assets to total loans plus OREO was 1.6% as of September 30, 2023, 1.5% as of June 30, 2023, and 1.4% as of September 30, 2022. Our allowance for credit losses to total loans was 1.3% as of September 30, 2023, 1.4% as of June 30, 2023, and 1.3% as of September 30, 2022.

Classified loans as of September 30, 2023 increased $25.7 million from June 30, 2023, and $39.5 million from September 30, 2022. The net increase from the second quarter of 2023 was driven by two additions totaling $17.6 million in commercial real estate – owner occupied, two additions totaling $17.3 million in construction, and offset by $6.8 million charged off in commercial real estate - investor. Remediation work continues on these three credits, with the goal of cash flow improvements with increased tenancy.  Reductions in commercial and multifamily classified loans were noted in the third quarter of 2023 from the linked quarter and prior year like quarter due to ongoing remediation efforts.

Allowance for Credit Losses on Loans and Unfunded Commitments

At September 30, 2023, our allowance for credit losses (“ACL”) on loans totaled $51.7 million, and our ACL on unfunded commitments, included in other liabilities, totaled $2.9 million.  In the third quarter of 2023, we recorded provision expense of $3.0 million based on historical loss rate updates, loan growth, our assessment of nonperforming loan metrics and trends, and estimated future credit losses. The third quarter’s provision expense consisted of a $3.0 million provision for credit losses on loans, and a $11,000 reversal of provision for credit losses on unfunded commitments.  The decrease in unfunded commitments was primarily due to an adjustment of 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 $6.6 million in the third quarter of 2023, which reduced the ACL. The majority of the third quarter charge offs were specific to two borrowers within commercial real estate on which we had existing specific allocations within the ACL of $4.7 million at June 30, 2023. The second quarter 2023 provision expense of $2.0 million consisted of a $2.4 million provision for credit losses on loans, and a $427,000 reversal of provision for credit losses on unfunded commitments. We recorded net charge-offs of $505,000 in the second quarter of 2023. In the third quarter of 2022, we recorded provision expense of $4.5 million based on our assessment of nonperforming loan metrics and trends and estimated future credit losses.  We recorded net charge-offs of $68,000 in the third quarter of 2022, which reduced the ACL. Our ACL on loans to total loans was 1.3% as of September 30, 2023 and 1.4% as of June 30, 2023, and 1.3% as of September 30, 2022.

The $235,000 decrease in our ACL on unfunded commitments at September 30, 2023, compared to June 30, 2023, was driven by a $11,000 reversal of provision expense in the quarter discussed above, as well as purchase accounting accretion on unfunded commitments recorded during the quarter.  The ACL on unfunded commitments totaled $2.9 million as of September 30, 2023, $3.1 million as of June 30, 2023, and $5.4 million as of September 30, 2022.

Deposits

Total deposits were $4.61 billion at September 30, 2023, a decrease of $103.3 million, or 2.2%, compared to $4.72 billion at June 30, 2023, primarily due to a decline in savings of $47.0 million, followed by a decrease of $35.0 million in non-interest bearing deposits and $29.3 million in money markets. The bulk of the linked quarter decline in deposit balances occurred in August 2023 and is consistent with seasonal historical trends related to tax payments and commercial customer business volumes. Total quarterly average deposits decreased $659.4 million, or 12.4%, in the year over year period, driven by declines in our average demand deposits of $225.1 million, and savings, NOW and money markets combined of $440.7 million. In general, the bulk of the decline in deposits year over year can be characterized as rate sensitive with significant flows and transfers into investing activities, materially offsetting the significant expansion in those same accounts in the immediate aftermath of the pandemic.

Borrowings

As of September 30, 2023, we had $435.0 million in other short-term borrowings due to short-term FHLB advances, compared to $485.0 million at June 30, 2023, and $25.0 million as of September 30, 2022.

During the second quarter of 2023, we redeemed all of the $45.0 million senior notes that were due in 2026.  This senior debt issuance carried an interest rate of 9.39% at the time of redemption, and upon redemption, the related deferred debt issuance costs of $362,000 were also recorded as interest expense, resulting in an effective cost of this debt issuance of 12.85% for the second quarter of 2023.

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.
