Old Second Bancorp, Inc. Reports Fourth Quarter 2023 Net Income of $18.2 Million,

or $0.40 per Diluted Share

AURORA, IL, January 24, 2024 – 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 2023. Our net income was $18.2 million, or $0.40 per diluted share, for the fourth quarter of 2023, compared to net income of $24.3 million, or $0.54 per diluted share, for the third quarter of 2023, and net income of $23.6 million, or $0.52 per diluted share, for the fourth quarter of 2022. Adjusted net income, a non-GAAP financial measure that excludes nonrecurring litigation related expenses and Visa portfolio liquidation and deconversion costs, as applicable, was $19.1 million, or $0.42 per diluted share, for the fourth quarter of 2023, compared to $24.8 million, or $0.55 per diluted share, for the third quarter of 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. Noteworthy items impacting fourth quarter 2023 results include a $1.2 million litigation reserve related to prior years’ overdraft fee compliance and $1.3 million in expense related to the fair value of mortgage servicing rights.

Net income decreased $6.1 million in the fourth quarter of 2023 compared to the third quarter of 2023. The decrease was primarily due to the increase of $5.0 million in provision for credit losses, a $1.3 million increase in interest expense, and a decrease in noninterest income of $1.1 million in the fourth quarter of 2023, which were partially offset by a $397,000 decrease in noninterest expense and a $1.4 million decrease in provision for income taxes. Net income decreased $5.4 million in the fourth quarter of 2023 compared to the fourth quarter of 2022, primarily due to an increase in provision for credit losses of $6.5 million and a decrease in net interest income of $2.9 million year over year due to rising market interest rates, which also resulted in an $8.8 million increase in interest expense. These decreases to net income in the fourth quarter of 2023 were partially offset by a decrease in noninterest expenses of $2.7 million. The fourth quarter of 2023 was minimally impacted by a pre-tax net loss on the call of securities of $2,000, compared to more significant pre-tax net losses on the sale of securities of $924,000 and $910,000 in the third quarter of 2023 and the fourth quarter of 2022, respectively.

Operating Results

●

Fourth quarter 2023 net income was $18.2 million, reflecting a $6.1 million decrease from the third quarter 2023, and a decrease of $5.4 million from the fourth quarter of 2022. Adjusted net income, as defined above, was $19.1 million for the fourth quarter of 2023, a decrease of $5.7 million from adjusted net income for the third quarter of 2023, and a decrease of $4.9 million from adjusted net income for the fourth quarter of 2022.

●

Net interest and dividend income was $61.2 million for the fourth quarter of 2023, reflecting a decrease of $1.8 million, or 2.8%, from the third quarter of 2023, and a decrease of $2.9 million, or 4.5%, from the fourth quarter of 2022.

●

We recorded a net provision for credit losses of $8.0 million in the fourth quarter of 2023, compared to a net provision for credit losses of $3.0 million in the third quarter of 2023, and a net provision for credit losses of $1.5 million in the fourth quarter of 2022.

●

Noninterest income was $8.7 million for the fourth quarter of 2023, a decrease of $1.1 million, or 11.6%, compared to $9.9 million for the third quarter of 2023, and a decrease of $217,000, or 2.4%, compared to $8.9 million for the fourth quarter of 2022.

●

Noninterest expense was $37.0 million for the fourth quarter of 2023, a decrease of $397,000, or 1.1% compared to $37.4 million for the third quarter of 2023, and a decrease of $2.7 million, or 6.7%, compared to $39.7 million for the fourth quarter of 2022.

●

We had a provision for income tax of $6.7 million for the fourth quarter of 2023, compared to a provision for income tax of $8.1 million for the third quarter of 2023 and a provision of $8.2 million for the fourth quarter of 2022. The effective tax rate for each of the periods presented was 26.9%, 25.1%, and 25.9%, respectively.

●

On January 16, 2024, our Board of Directors declared a cash dividend of $0.05 per share payable on February 5, 2024, to stockholders of record as of January 26, 2024.

Chairman, President and Chief Executive Officer Jim Eccher said “Profitability at Old Second remains exceptionally strong and balance sheet strengthening continues with our tangible common equity to tangible assets ratio increasing by 86 basis points linked quarter to 8.53%. We believe we are being proactive in addressing commercial real estate loans facing deterioration from higher interest rates, declining appraisal values and cash flow pressures. Importantly, the total of substandard and criticized loans are now at their lowest levels since June 2022 as we have seen previously identified loans work toward resolution and the pace of downgrades has improved dramatically. The loan portfolio, exclusive of office CRE and healthcare, has remained well behaved and we remain confident in our credit quality overall. Absent a significant recession, I am optimistic that this quarter will mark the inflection point in our asset quality trends as we have seen the bulk of our loan portfolio reprice and transition into the current interest rate environment. This expectation comes despite Old Second maintaining an economic view that is significantly more cautious than consensus market forecasts. Our focus therefore remains on assessing and monitoring risks within the loan portfolio and optimizing the earning asset mix in order to reduce our overall sensitivity to interest rates. Net interest margin trends are stable and income statement efficiency remains at record levels. Marginal spreads in deposit and lending markets remain exceptionally tight but balance sheet flexibility and the expectation for continuing record efficiency gives me confidence we are well positioned to deliver another strong year in 2024. I look forward to the opportunity to demonstrate the strength of the franchise we have built.”

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 $68.8 million at December 31, 2023, $63.3 million at September 30, 2023, and $32.9 million at December 31, 2022. Nonperforming loans, as a percent of total loans, were 1.7% at December 31, 2023, 1.6% at September 30, 2023, and 0.9% at December 31, 2022. The increase in the fourth quarter of 2023 is driven by the downgrade of a few credits during the quarter, due primarily to office-related loans and assisted living properties within the commercial real estate-investor portfolio and debt service coverage shortfalls.

●

Total loans were $4.04 billion at December 31, 2023, reflecting an increase of $13.4 million compared to September 30, 2023, and an increase of $173.3 million compared to December 31, 2022. The increase year over year was largely driven by the growth in leases, commercial real estate-investor, and multifamily portfolios. Average loans (including loans held-for-sale) for the fourth quarter of 2023 totaled $4.02 billion, reflecting an increase of $5.6 million from the third quarter of 2023 and an increase of $138.3 million from the fourth quarter of 2022.

●

Available-for-sale securities totaled $1.19 billion at December 31, 2023, compared to $1.23 billion at September 30, 2023, and $1.54 billion at December 31, 2022. The unrealized mark to market loss on securities totaled $84.2 million as of December 31, 2023, compared to $120.5 million as of September 30, 2023, and $123.5 million as of December 31, 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 December 31, 2023, there were no securities sold, however $55.9 million of maturities and calls resulted in net realized losses of $2,000, compared to sales of $65.6 million during the quarter ended September 30, 2023, which resulted in net realized losses of $924,000, and security sales of $27.7 million for the quarter ended December 31, 2022, which resulted in net realized losses of $910,000. We may continue to sell strategically identified securities as opportunities arise.

¹ Tax equivalent (TE) basis is calculated using a marginal tax rate of 21% in 2023 and 2022. See the discussion entitled “Non-GAAP Presentations” below and the tables beginning on page 17 that provides 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 expense of $922,000 for the fourth quarter of 2023, loan fee expense of $780,000 for the third quarter of 2023, and loan fee income of $916,000 the fourth quarter of 2022. Nonaccrual loans are included in the above stated average balances.

The increased yield of six basis points on interest earning assets compared to the linked period was driven by repricing within the existing variable rate portfolios for securities available-for-sale. 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 66 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 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 fourth quarter of 2022 through the fourth quarter of 2023, from $3.13 billion to $2.74 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 89 basis points for the quarter ended December 31, 2023, from 65 basis points for the quarter ended September 30, 2023, and from 17 basis points for the quarter ended December 31, 2022. A 29 basis point increase in the cost of money market funds for the quarter ended December 31, 2023 compared to prior linked quarter, and a 105 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 December 31, 2023 increased by 57 basis points and 176 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 fourth quarter of 2023, compared to the third quarter of 2023, primarily due to the decrease in average other short-term borrowings of $36.5 million stemming from a decrease in average FHLB advances over the prior quarter. Partially offsetting the decrease in borrowing costs in the fourth quarter of 2023 was the increase in average securities sold under repurchase agreements of $3.6 million. The increase of $346.4 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) decreased five basis points to 4.59% for the fourth quarter of 2023, compared to 4.64% for the third quarter of 2023, and decreased one basis point compared to 4.60% for the fourth quarter of 2022. Our net interest margin (TE) decreased four basis points to 4.62% for the fourth quarter of 2023, compared to 4.66% for the third quarter of 2023, and decreased one basis point compared to 4.63% for the fourth quarter of 2022. The decrease in the fourth quarter, compared to the prior quarter, is primarily due to the growth in interest expense due to the rising interest rate environment and its effect on interest bearing deposits. The decrease in the fourth quarter of 2023, compared to the prior year like quarter, is primarily due to an increase in market interest rates, and the related 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.

Noninterest income decreased $1.1 million, or 11.6%, in the fourth quarter of 2023, compared to the third quarter of 2023, and decreased $217,000, or 2.4%, compared to the fourth quarter of 2022. The decrease from the third quarter of 2023 was primarily driven by a $1.6 million decrease in residential mortgage banking revenue, a $378,000 decrease in the cash surrender value of BOLI, and a $114,000 decrease in other income, partially offset by a $922,000 decrease in security losses, net, based on strategic sales in the third quarter of 2023 compared to none during the fourth quarter of 2023.

The decrease in noninterest income of $217,000 in the fourth quarter of 2023, compared to the fourth quarter of 2022, is primarily due to an increase of $846,000 on mortgage servicing rights mark to market losses, a $284,000 decrease in card related income, and a $384,000 decrease in other income. These decreases were partially offset by a $197,000 increase in wealth management income, a $908,000 decrease in security losses, net, based on strategic sales in the fourth quarter of 2022 compared to none during the fourth quarter of 2023, and a $165,000 increase in the cash surrender value of BOLI due to market interest rate changes.

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 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, litigation expense, and acquisition-related costs, net of gains on branch sales (as applicable), 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 fourth quarter of 2023 decreased $397,000, or 1.1%, compared to the third quarter of 2023, and decreased $2.7 million, or 6.7%, compared to the fourth quarter of 2022. The decrease in the fourth quarter of 2023 compared to the third quarter of 2023 was attributable to a $1.7 million decrease in salaries and employee benefits, primarily due to a decrease in the officer incentive accrual and to a lesser extent various components of salary expense. Also contributing to the decrease in the fourth quarter of 2023 was a $161,000 decrease in FDIC insurance due to a reduction in total assets assessed. Partially offsetting the decrease in noninterest expense in the fourth quarter of 2023 was a $311,000 increase in occupancy, furniture and equipment, a $369,000 increase in computer and data processing, a $290,000 increase in advertising expense, and a $245,000 increase in OREO related expenses due to two additions to OREO during the fourth quarter of 2023 quarter totaling $4.9 million.

The year over year decrease in noninterest expense is primarily attributable to a $2.9 million decrease in salaries and employee benefits, primarily due to a decrease in various components of salary expense as well as officers’ incentives. Also contributing to the decrease was a $311,000 decrease in occupancy, furniture and equipment, a $687,000 decrease in computer and data processing, and a $123,000 decrease in consulting and management fees. The elevated expense totals in the fourth quarter of 2022 were driven by the final merger-related costs recorded stemming from the West Suburban acquisition in December 2021. Partially offsetting the decrease in noninterest expense in the fourth quarter of 2023, compared to the fourth quarter of 2022, was a $253,000 increase in advertising expenses, a $184,000 increase in OREO related expenses, and a $854,000 increase in other expenses due to a $1.2 million litigation expense recorded in the fourth quarter of 2023 for a pending overdraft fee compliance claim.

Our securities portfolio totaled $1.19 billion fair market value as of December 31, 2023, a decrease of $36.8 million from $1.23 billion as of September 30, 2023, and a decrease of $346.5 million since December 31, 2022. The portfolio reduction of $36.8 million in the fourth quarter of 2023, compared to the prior quarter-end, was due to maturities and calls of $55.9 million as well as paydowns of $25.6 million, partially offset by the effects of declining interest rates which increased fair market value. Net unrealized losses at December 31, 2023 were $84.2 million, compared to $120.5 million at September 30, 2023 and $123.5 million at December 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.

¹As 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 $55.7 million, net of purchase accounting adjustments, at December 31, 2023. PCD loans that meet the definition of nonperforming loans are included in our nonperforming disclosures. Nonperforming loans to total loans was 1.7% as of December 31, 2023, 1.6% as of September 30, 2023, and 0.9% as of December 31, 2022. Nonperforming assets to total loans plus OREO was 1.8% as of December 31, 2023, 1.6% as of September 30, 2023, and 0.9% as of December 31, 2022. Our allowance for credit losses to total loans was 1.1% as of December 31, 2023, and 1.3% as of September 30, 2023 and December 31, 2022.

The following table shows classified loans by segment, which include nonaccrual loans, PCD loans if the risk rating so indicates, and all other loans considered substandard, for the following periods.

Classified loans as of December 31, 2023 decreased by $20.5 million from September 30, 2023, and increased by $23.9 million from December 31, 2022. The net decrease from the third quarter of 2023 was mostly driven by seven loans that had principal charge offs, totaling $15.8 million, seven loans that were upgraded totaling $11.8 million, and two loans that were transferred to OREO, totaling $4.9 million. These decreases in classified loans in the fourth quarter were offset by $18.6 million of additions, primarily driven by three loans in commercial real estate – owner occupied which totaled $11.1 million and seven loans in commercial which totaled $4.2 million. Remediation work continues on these credits, with the goal of cash flow improvements with increased tenancy. Reductions in commercial classified loans were noted in the fourth quarter of 2023 from the linked quarter due to ongoing remediation efforts.

Allowance for Credit Losses on Loans and Unfunded Commitments

At December 31, 2023, our allowance for credit losses (“ACL”) on loans totaled $44.3 million, and our ACL on unfunded commitments, included in other liabilities, totaled $2.7 million. In the fourth quarter of 2023, we recorded provision expense of $8.0 million based on historical loss rate updates, loan growth, our assessment of nonperforming loan metrics and trends, and estimated future credit losses. The fourth quarter’s provision expense consisted of a $8.0 million provision for credit losses on loans, and a $6,000 provision for credit losses on unfunded commitments. The increase in ACL on 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 $15.5 million in the fourth quarter of 2023, which reduced the ACL. The majority of the fourth quarter charge offs were specific to seven borrowers within the commercial real estate portfolio on which we had existing specific allocations within the ACL of $2.5 million at September 30, 2023. The third quarter 2023 provision expense of $3.0 million 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. We recorded net charge-offs of $6.6 million in the third quarter of 2023. In the fourth quarter of 2022, we recorded provision expense of $1.5 million based on our assessment of nonperforming loan metrics and trends and estimated future credit losses. We recorded net charge-offs of $940,000 in the fourth quarter of 2022, which reduced the ACL. Our ACL on loans to total loans was 1.1% as of December 31, 2023 and 1.3% as of September 30, 2023 and December 31, 2022.

The $143,000 decrease in our ACL on unfunded commitments at December 31, 2023, compared to September 30, 2023, was driven by purchase accounting accretion of $149,000 on unfunded commitments recorded during the quarter, partially offset by $6,000 of provision expense in the quarter discussed above. The ACL on unfunded commitments totaled $2.7 million as of December 31, 2023, $2.9 million as of September 30, 2023, and $5.1 million as of December 31, 2022.

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

Gross charge-offs for the fourth quarter of 2023 were $16.0 million, compared to $6.9 million for the third quarter of 2023 and $1.1 million for the fourth quarter of 2022. Gross recoveries were $491,000 for the fourth quarter of 2023, compared to $339,000 for the third quarter of 2023, and $136,000 for the fourth quarter of 2022. Continued recoveries are indicative of the ongoing aggressive efforts by management to effectively manage and resolve prior charge-offs.

Deposits

Total deposits were $4.57 billion at December 31, 2023, a decrease of $43.6 million, or 0.9%, compared to $4.61 billion at September 30, 2023, primarily due to a decline in savings of $32.2 million, followed by a decrease of $30.9 million in money markets and $27.8 million in non-interest bearing deposits. The large decreases were partially offset by an increase of $49.9 million in certificates of deposit. The bulk of the linked quarter decline in deposit balances occurred in October 2023 and is consistent with seasonal historical trends related to tax payments and commercial customer business volumes. Total quarterly average deposits decreased $636.6 million, or 12.2%, in the year over year period, driven by declines in our average demand deposits of $245.2 million, and savings, NOW and money markets combined of $438.8 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 December 31, 2023, we had $405.0 million in other short-term borrowings due to short-term FHLB advances, compared to $435.0 million at September 30, 2023, and $90.0 million as of December 31, 2022.

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.
