Old Second Bancorp, Inc. Reports Second Quarter 2023 Net Income of $25.6 Million,

or $0.56 per Diluted Share

AURORA, IL, July 19, 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 second quarter of 2023.  Our net income was $25.6 million, or $0.56 per diluted share, for the second quarter of 2023, compared to net income of $23.6 million, or $0.52 per diluted share, for the first quarter of 2023, and net income of $12.2 million, or $0.27 per diluted share, for the second quarter of 2022. Adjusted net income, a non-GAAP financial measure that excludes net pre-tax losses totaling $29,000 from branch sales, was also $25.6 million, or $0.56 per diluted share, for the second quarter of 2023, compared to $23.4 million, or $0.52 per diluted share, for the first quarter of 2023, and $13.8 million, or $0.31 per diluted share, for the second quarter of 2022.  See the discussion entitled “Non-GAAP Presentations” below and the tables beginning on page 16 that provide a reconciliation of each non-GAAP measure to the most comparable GAAP equivalent.

Net income increased $2.0 million in the second quarter of 2023 compared to the first quarter of 2023. The increase was primarily due to the increase in interest and dividend income of $3.7 million, the decrease of $1.5 million in provision for credit losses, and a decrease in noninterest expense of $1.1 million in the second quarter of 2023, which were partially offset by a $4.2 million increase in interest expense. Net income increased $13.3 million in the second quarter of 2023 compared to the second quarter of 2022, primarily due to an increase in net interest income year over year due to rising market interest rates.  The second quarter of 2023 was impacted by the recognition of $362,000 of deferred issuance costs related to the early payoff of approximately $45.0 million in senior debt on June 30, 2023, and a pre-tax net loss on the sale of securities of $1.5 million, compared to pre-tax net losses on the sale of securities of $1.7 million in the first quarter of 2023, and pre-tax net losses on the sale of securities of $33,000 in the second quarter of 2022.

Operating Results

Second quarter 2023 net income was $25.6 million, reflecting a $2.0 million increase from the first quarter 2023, and an increase of $13.3 million from the second quarter of 2022.  Adjusted net income, a non-GAAP financial measure that excludes acquisition-related costs, net of gains on branch sales, was $25.6 million for the second quarter of 2023, an increase of $2.2 million from adjusted net income for the first quarter of 2023, and an increase of $11.8 million from adjusted net income for the second quarter of 2022.
Net interest and dividend income was $63.6 million for the second quarter of 2023, reflecting a decrease of $506,000 from the first quarter of 2023, and an increase of $18.3 million, or 40.5%, from the second quarter of 2022.
--- ---
We recorded a net provision for credit losses of $2.0 million in the second quarter of 2023, compared to a net provision for credit losses of $3.5 million in the first quarter of 2023, and a net provision for credit losses of $550,000 in the second quarter of 2022.
--- ---
Noninterest income was $8.2 million for the second quarter of 2023, an increase of $873,000, or 11.9%, compared to $7.4 million for the first quarter of 2023, and a decrease of $988,000, or 10.7%, compared to $9.2 million for the second quarter of 2022.

Noninterest expense was $34.8 million for the second quarter of 2023, a decrease of $1.1 million, or 3.0% compared to $35.9 million for the first quarter of 2023, and a decrease of $2.4 million, or 6.5%, compared to $37.2 million for the second quarter of 2022.
We had a provision for income tax of $9.4 million for the second quarter of 2023, compared to a provision for income tax of $8.4 million for the first quarter of 2023 and a provision of $4.4 million for the second quarter of 2022.

On July 18, 2023, our Board of Directors declared a cash dividend of $0.05 per share payable on August 7, 2023, to stockholders of record as of July 28, 2023.

President and Chief Executive Officer Jim Eccher said “Old Second reported strong results in the second quarter as we earned $25.6 million in net income, ROAA of 1.73% and ROATCE of 25.30%.  Adjusting for merger related items, our earnings per share increased by 81% over the second quarter 2022.  Our performance over the last year has been driven by the strength of the core deposit franchise we have built here at Old Second. Stable funding costs combined with quality loan growth have resulted in 146 basis points of expansion in our tax equivalent net interest margin over the same quarter last year. The efficiency ratio in the second quarter of 2023 was 46.8% on a GAAP basis and reflects strong balance sheet management, expense discipline in an inflationary environment and successful investments in lending teams and sales people over the last eighteen months.

“We are exceptionally pleased with our financial performance thus far in 2023 but we remain focused on the little things, such as receiving fair risk adjusted returns on our investments in a time of increasing funding costs while constantly assessing risks both within the loan portfolio and in the broader economy.  To that end, we are continuing to build capital quickly and remain focused on optimizing the earning asset mix and reducing our overall sensitivity to interest rates in a prudent manner. Balance sheet growth over the remainder of the year is expected to be minimal and deposit funding costs are expected to increase modestly as we respond to competition in our markets.  Any additional interest rate increases would benefit Old Second but not to the degree of prior increases.  Tangible book value per share is compounding nicely and we are nearing targeted capital levels less than two years after a significant acquisition and following a period of significant volatility in interest rates.  We look to finish the second half of the year on a strong note and effectively position Old Second for the years ahead.”

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 $61.2 million at June 30, 2023, $64.5 million at March 31, 2023, and $42.1 million at June 30, 2022.  Nonperforming loans, as a percent of total loans, were 1.5% at June 30, 2023, 1.6% at March 31, 2023, and 1.2% at June 30, 2022.  The decrease in the second quarter of 2023 is driven by the upgrade of a few credits during the quarter, due to improved borrower financial performance and debt service coverage enhancements.
Total loans were $4.02 billion at June 30, 2023, reflecting an increase of $12.2 million compared to March 31, 2023, and an increase of $390.5 million compared to June 30, 2022. The increase year over year was largely driven by the growth in commercial, leases, commercial real estate-investor, and multifamily portfolios.  Average loans (including loans held-for-sale) for the second quarter of 2023 totaled $4.04 billion, reflecting an increase of $107.7 million from the first quarter of 2023 and an increase of $531.3 million from the second quarter of 2022.
--- ---
Available-for-sale securities totaled $1.34 billion at June 30, 2023, compared to $1.46 billion at March 31, 2023, and $1.73 billion at June 30, 2022.  The unrealized mark to market loss on securities totaled $112.4 million as of June 30, 2023, compared to $105.6 million as of March 31, 2023, and $89.8 million as of June 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 June 30, 2023, securities sales of $74.0 million resulted in net realized losses of $1.5 million, compared to sales of $66.2 million during the quarter ended March 31, 2023, which resulted in net realized losses of $1.7 million, and one security sold for the quarter ended June 30, 2022 that resulted in a loss of $33,000.  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 16 that provides a reconciliation of each non-GAAP measures 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 16, and includes loan fee expense of $242,000 for the second quarter of 2023, and loan fee expense of $730,000 and $588,000 for the first quarter of 2023 and the second quarter of 2022, respectively. Nonaccrual loans are included in the above stated average balances.

The increased yield of 20 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 206 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 commercial, leases, 4

and commercial real estate 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 and timely purchases of higher yielding securities, as we work to increase the weighted average yield in the portfolio.

Average balances of interest bearing deposit accounts have decreased steadily since the second quarter of 2022 through the second quarter of 2023, from $3.34 billion to $2.87 billion, with these decreases reflected in all deposit categories. We have continued to control the cost of funds over the periods reflected, with the rate of overall interest bearing deposits increasing to 40 basis points for the quarter ended June 30, 2023, from 25 basis points for the quarter ended March 31, 2023, and from seven basis points for the quarter ended June 30, 2022. A 25 basis point increase in the cost of money market funds for the quarter ended June 30, 2023 compared to prior linked quarter, and a 59 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 June 30, 2023 also increased by 44 basis points and 83 basis points in the quarter over linked quarter and year over year quarters, respectively, primarily due to CD rate specials we offered.

Borrowing costs increased in the second quarter of 2023, primarily due to the increase in average short term borrowings of $201.7 million stemming from growth in average FHLB advances over the prior quarter, and an average increase of $402.5 million year over year 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 increase, as this issuance references three month LIBOR, and rising market interest rates as well as recognition of $362,000 of deferred issuance costs upon redemption resulted in a 381 basis point increase to 12.85% for the quarter ended June 30, 2023, compared to 9.04% for the quarter ended March 31, 2023, and a 764 basis point increase from 5.21% for the quarter ended June 30, 2022. On June 30, 2023, we redeemed all of the $45.0 million senior notes, net of deferred issuance costs, which were originally due in 2026. 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 11 basis points to 4.61% for the second quarter of 2023, compared to 4.72% for the first quarter of 2023, and increased 145 basis points compared to 3.16% for the second quarter of 2022.  Our net interest margin (TE) decreased 10 basis points to 4.64% for the second quarter of 2023, compared to 4.74% for the first quarter of 2023, but increased 146 basis points compared to 3.18% for the second quarter of 2022.  The decrease in the current quarter, compared to the prior quarter, is primarily due to increases in interest expense from FHLB advances and the redemption of the senior notes. The increase in the current 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 16 that provide a reconciliation of each non-GAAP measure to the most comparable GAAP equivalent.

Noninterest income increased $873,000, or 11.9%, in the second quarter of 2023, compared to the first quarter of 2023, and decreased $988,000, or 10.7%, compared to the second quarter of 2022.  The increase from the first quarter of 2023 was primarily driven by a $621,000 increase in mortgage servicing rights (“MSR”) mark to market gains, a $128,000 decrease in securities losses, net, based on strategic sales, and a $446,000 increase in card related income primarily due to increased activity.  These increases in noninterest income in the second quarter of 2023, compared to the first quarter of 2023, were partially offset by a $716,000 decrease in other income driven by credits received in the first quarter of 2023 from a few vendors related to prior year service discounts.

The decrease in noninterest income of $988,000 in the second quarter of 2023, compared to the second quarter of 2022, is primarily due to an increase in security losses of $1.5 million on strategic sales for the quarter ended June 30, 2023. These decreases were partially offset by a $660,000 increase in net gains on sales of mortgage loans and a $346,000 increase in the cash surrender value of BOLI due to market interest rate changes.

^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, 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, and includes a tax equivalent adjustment on the change in cash surrender value of BOLI.  See the discussion entitled “Non-GAAP Presentations” below and the table on page 17 that provides a reconciliation of this non-GAAP financial measure to the most comparable GAAP equivalent.

Noninterest expense for the second quarter of 2023 decreased $1.1 million, or 3.0%, compared to the first quarter of 2023, and decreased $2.4 million, or 6.5%, compared to the second quarter of 2022.  The decrease in the second quarter of 2023 compared to the first quarter of 2023 was attributable to a $450,000 decrease in salaries and employee benefits, primarily due to reductions in employee benefits expense related to a decline in group insurance premiums and payroll taxes, partially offset by an increase in salaries and the officer incentive accrual.  Also contributing to the decrease in the second quarter of 2023 was a $484,000 decrease in computer and data processing costs as the first quarter of 2023 included additional costs due to timing of software contracts and incentives.   Noninterest expense was further decreased in the second quarter of 2023 as there was no OREO valuation adjustment recorded compared to a $269,000 OREO valuation reserve recorded on two properties in the first quarter of 2023, reflected in other real estate owned expense, net. 6

The year over year decrease in noninterest expense is primarily attributable to a $2.7 million decrease in computer and data processing expenses and a $319,000 decrease in net teller & bill paying expense, both stemming from acquisition related costs in the second quarter of 2022 from our West Suburban acquisition. Partially offsetting the decrease in noninterest expense in the second quarter of 2023, compared to the second quarter of 2022, was a $466,000 increase in salaries and employee benefits and a $593,000 increase in occupancy, furniture and equipment expenses. Officer incentive compensation increased $735,000 in the second quarter of 2023, compared to the second quarter of 2022, as incentive accruals increased in the current year due to growth in our commercial and sponsored finance lending team staffing year over year, as well as loan growth in the year over year periods.

The portfolio decrease of $119.4 million in the second quarter of 2023, compared to the prior quarter-end, was due to security sales of $74.0 million, which resulted in a net realized loss of $1.5 million, as well as paydowns of $30.9 million.  Net unrealized losses at June 30, 2023 were $112.4 million, compared to $105.6 million at March 31, 2023 and $89.8 million at June 30, 2022. The year over year increase 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 all except one publicly issued security rated AA or better, and displaying an effective duration of approximately 3 years.

^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 $64.1 million, net of purchase accounting adjustments, at June 30, 2023.  PCD loans that meet the definition of nonperforming loans are included in our nonperforming disclosures.  Nonperforming loans to total loans was 1.5% as of June 30, 2023, 1.6% as of March 31, 2023, and 1.2% as of June 30, 2022. Nonperforming assets to total loans plus OREO was 1.5% as of June 30, 2023, 1.6% as of March 31, 2023, and 1.2% as of June 30, 2022. Our allowance for credit losses to total loans was 1.4% as of June 30, 2023, and 1.3% as of both March 31, 2023 and June 30, 2022.

Classified loans as of June 30, 2023 increased $2.3 million from March 31, 2023, and $24.4 million from June 30, 2022. The net increase from the first quarter of 2023 was driven by a $3.6 million addition in commercial real estate – investor and two additions totaling $2.2 million in commercial real estate – owner occupied. 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 second 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 June 30, 2023, our allowance for credit losses (“ACL”) on loans totaled $55.3 million, and our ACL on unfunded commitments, included in other liabilities, totaled $3.1 million.  In the second quarter of 2023, we recorded provision expense of $2.0 million based on historical loss rate updates, loan growth, our assessment of nonperforming loan metrics and trends, and estimated future credit losses. The second quarter’s provision expense 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.  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 $505,000 in the second quarter of 2023, which reduced the ACL. The first quarter 2023 provision expense of $3.5 million consisted of a $4.7 million provision for credit losses on loans, and a $1.2 million reversal of provision for credit losses on unfunded commitments. We recorded net charge-offs of $740,000 in the first quarter of 2023. In the second quarter of 2022, we recorded provision expense of $550,000 based on our assessment of nonperforming loan metrics and trends and estimated future credit losses.  We recorded net charge-offs of $250,000 in the second quarter of 2022, which reduced the ACL. Our ACL on loans to total loans was 1.4% as of June 30, 2023 and 1.3% as of March 31, 2023 and June 30, 2022.

The $650,000 decrease in our ACL on unfunded commitments at June 30, 2023, compared to March 31, 2023, was driven by a $427,000 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 $3.1 million as of June 30, 2023, $3.8 million as of March 31, 2023, and $4.7 million as of June 30, 2022.

Gross charge-offs for the second quarter of 2023 were $733,000, compared to $1.0 million for the first quarter of 2023 and $386,000 for the second quarter of 2022.  Gross recoveries were $228,000 for the second quarter of 2023, compared to $282,000 for the first quarter of 2023, and $136,000 for the second 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 $4.72 billion at June 30, 2023, a decrease of $179.6 million, or 3.7%, compared to $4.90 billion at March 31, 2023, primarily due to a decline in money markets of $67.8 million, followed by a decrease of $58.2 million in savings and $52.5 million in non-interest bearing deposits. The bulk of the linked quarter decline in deposit balances occurred in April 2023 and is consistent with seasonal historical trends related to tax payments and commercial customer business volumes. Total quarterly average deposits decreased $667.2 million, or 12.2%, in the year over year period, driven by declines in our average demand deposits of $199.2 million, and savings, NOW and money markets combined of $435.5 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. 9

Borrowings

As of June 30, 2023, we had $485.0 million in other short-term borrowings due to short-term FHLB advances, compared to $315.0 million at March 31, 2023 and no short-term borrowings outstanding as of June 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.

During the first quarter of 2023, we paid off a $9.0 million term note payable upon maturity as of February 24, 2023.  The note payable carried an interest rate of 6.32% at maturity.  Please see Notes 9 and 10 of our Annual Report on Form 10-K for the year ended December 31, 2022, for further discussion of our borrowings.

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 6.

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 16 provide a reconciliation of each non-GAAP financial measure to the most comparable GAAP equivalent.
