"We began this year with another solid quarter, highlighted by strong earnings. The successful workout of a large commercial real estate loan that entered non-accrual status at the end of 2022 aided our first quarter performance. Our team remains conscious of the current credit environment as we seek to limit risk while still taking steps to grow prudently. Excluding loan payoff activity that we initiated, we experienced modest loan growth and expect that to continue throughout the year. Orrstown's Wealth Management team is leading the way in generating strong fee income. As in prior years, expenses were higher in the first quarter and, excluding merger-related costs, are expected to normalize in the second quarter. Our liquidity position was bolstered by strong deposit growth, which included successful CD and money market production, as well as seasonal and short-term balances from which we expect some runoff,” commented Thomas R. Quinn, Jr., President and Chief Executive Officer.

DISCUSSION OF RESULTS

Balance Sheet

Loans

Loans held for investment increased by $4.8 million from December 31, 2023 to March 31, 2024. The residential mortgage portfolio increased by $7.9 million in the three months ended March 31, 2024 from continued portfolio production. Commercial loans decreased by $2.3 million from December 31, 2023 to March 31, 2024; however, the balance at March 31, 2024 reflected the payoffs of a commercial real estate loan on nonaccrual status totaling $13.4 million and a special mention commercial loan totaling $7.2 million during the first quarter of 2024.

Loans held-for-sale decreased by $5.3 million to $0.5 million at March 31, 2024 from $5.8 million at December 31, 2023. During the first quarter of 2024, the Bank sold a portfolio of residential mortgage loans that had a book value, which approximated fair value, of $5.1 million at December 31, 2023.

Investment Securities

Investment securities, all of which are classified as available-for-sale, increased by $1.4 million to $514.9 million at March 31, 2024 compared to $513.5 million at December 31, 2023. During the first quarter of 2024, purchases of $21.8 million were partially offset by a call of a non-agency collateralized mortgage obligation ("CMO") totaling $10.0 million, paydowns of $8.1 million and an increase in net unrealized losses on investment securities of $1.8 million. The overall duration of the Company's investment securities portfolio was 4.4 years at March 31, 2024. See Appendix B for a summary of the Bank's investment securities at March 31, 2024, highlighting their concentrations, credit ratings and credit enhancement levels.

Deposits

During the first quarter of 2024, deposits increased by $137.1 million totaling approximately $2.7 billion at March 31, 2024 compared to $2.6 billion at December 31, 2023. In the first quarter of 2024, interest-bearing demand deposits increased by $56.9 million, time deposits increased by $50.4 million and money market deposits increased by $48.7 million. These increases were partially offset by decreases in non-interest bearing deposits of $12.4 million and savings deposits of $6.5 million. The increase in interest-bearing demand deposits reflects some seasonal public funds activity in addition to balances that are believed to be short-term in nature. The increase in time deposits was attributable to promotional offerings of up to 18-month terms. The declines in noninterest-bearing deposits and savings deposits were primarily due to clients shifting to higher-yielding products within the Bank. At March 31, 2024, deposits that are uninsured and not collateralized totaled $413.5 million, or 15%, of total deposits compared to $442.7 million, or 17%, of total deposits at December 31, 2023. The Bank's loan-to-deposit ratio was lowered to 85% at March 31, 2024 compared to 90% at December 31, 2023 due to the increase in deposits during the first quarter of 2024.

Borrowings

The Bank actively manages its liquidity position through its various sources of funding to meet the needs of its clients. FHLB advances and other borrowings decreased by $22.5 million to $115.0 million at March 31, 2024 compared to $137.5 million at December 31, 2023. The Bank repaid overnight borrowings during the first quarter of 2024 based on available liquidity from deposits. The Bank seeks to maintain sufficient liquidity to ensure client needs can be addressed in a timely basis. The Bank had available alternative funding sources, such as FHLB advances and other wholesale options, of approximately $1.0 billion at March 31, 2024.

Income Statement

Net Interest Income and Margin

Net interest income was $26.9 million for the three months ended March 31, 2024 compared to $26.0 million for the three months ended December 31, 2023. The net interest margin, on a tax equivalent basis, increased to 3.77% in the first quarter of 2024 from 3.71% in the fourth quarter of 2023. During the three months ended March 31, 2024, the Bank recognized interest income previously applied to principal of $1.6 million from the payoff of a commercial real estate loan on nonaccrual status, which contributed 21 basis points to net interest margin. The net interest margin was negatively impacted by the increase in funding costs of 27 basis points due primarily to higher interest-bearing deposit balances. Also, the interest rate increased on the subordinated notes, which converted from a fixed rate to a floating rate on December 30, 2023. In addition, the net interest margin was lower by six basis points from excess cash compared to the fourth quarter of 2023.

Interest income on loans, on a tax equivalent basis, increased by $2.3 million to $36.4 million for the three months ended March 31, 2024 compared to $34.1 million for the three months ended December 31, 2023, which was primarily due to the aforementioned interest recovery.

Interest income on investment securities, on a tax equivalent basis, was $5.7 million for the first quarter of 2024 compared to $5.9 million in the fourth quarter of 2023. The decrease in interest income on investment securities was primarily caused by the call of one higher-yielding non-agency CMO of $10.0 million during the three months ended March 31, 2024 as well as accelerated discount accretion in the fourth quarter of 2023.

Interest expense, on a tax equivalent basis, increased by $1.8 million to $15.8 million for the three months ended March 31, 2024 compared to $14.0 million for the three months ended December 31, 2023 due primarily to higher average deposit balances and an increase in rates on deposits and the subordinated notes. Average interest-bearing deposits increased by $55.1 million during the three months ended March 31, 2024 compared to the three months ended December 31, 2023.

Provision for Credit Losses

The Company recorded a provision for credit losses of $0.3 million for the three months ended March 31, 2024 compared to $0.4 million for the three months ended December 31, 2023. The allowance for credit losses ("ACL") on loans increased to $29.2 million at March 31, 2024 from $28.7 million at December 31, 2023. The ACL was impacted primarily by a reduction in prepayment speed assumptions within the quantitative model due to current economic conditions partially offset by an improvement in the gross domestic product forecast. The ACL to total loans was 1.27% at March 31, 2024 compared to 1.25% at December 31, 2023. Net recoveries were less than $0.1 million for both the three months ended March 31, 2024 and December 31, 2023.

Special mention loans decreased by $8.2 million from $24.2 million at December 31, 2023 to $16.0 million at March 31, 2024 primarily due to repayments, including $7.2 million from one commercial client. Classified loans decreased by $6.0 million to $49.0 million at March 31, 2024 from $55.0 million at December 31, 2023. The decrease in classified loans was primarily due to repayments of $15.4 million, including the payoff of one commercial real estate loan totaling $13.4 million, partially offset by downgrades of $9.5 million, including one commercial relationship totaling $6.3 million. Non-accrual loans decreased by $12.6 million to $12.9 million at March 31, 2024 from $25.5 million at December 31, 2023 primarily due to the payoff of one commercial real estate loan totaling $13.4 million. Management believes the ACL to be adequate based on current asset quality metrics and economic conditions.

Management regularly analyzes the commercial real estate portfolio, which includes the review of occupancy, cash flows, expenses and expiring leases, as well as the location of the real estate. At March 31, 2024, the Company had $225.9 million in loans related to office space compared to $236.4 million at December 31, 2023. The weighted average loan-to-value ratio was 56% and the weighted average debt coverage ratio was 1.82x at March 31, 2024. Management believes that the office space portfolio is well-diversified and includes only limited exposure to properties located in major metro markets (approximately 2% of the total commercial real estate loan balance as of March 31, 2024).

Noninterest Income

Noninterest income increased by $0.1 million to $6.6 million in the three months ended March 31, 2024 compared to $6.5 million in the three months ended December 31, 2023.

4

For the three months ended March 31, 2024, mortgage banking income increased by $0.4 million compared to the fourth quarter of 2023. During the first quarter of 2024, residential mortgage sales totaled $14.7 million, including a portfolio of loans to another financial institution, compared to $3.7 million during the fourth quarter of 2023. Market conditions and elevated interest rates continued to hinder mortgage production.

Wealth management income increased by $0.2 million in the three months ended March 31, 2024 compared to the three months ended December 31, 2023 due to both new client generation and strong market conditions.

During the first quarter of 2024, the Company recorded swap fee income of $0.2 million compared to $0.6 million in the three months ended December 31, 2023. Swap fee income fluctuates based on market conditions and client demand.

Noninterest Expenses

Noninterest expenses increased by $0.1 million to $22.5 million in the three months ended March 31, 2024 from $22.4 million in the three months ended December 31, 2023.

Salaries and benefits expense increased by $1.0 million to $13.8 million for the three months ended March 31, 2024 compared to $12.8 million for the three months ended December 31, 2023. The increase is primarily attributable to an increase in employee benefit costs, including social security and unemployment taxes, which are typically higher at the beginning of the year, and increased incentive compensation associated with the prior year's performance.

Other operating expenses decreased by $0.6 million to $2.0 million during the first quarter of 2024 compared to $2.6 million during the fourth quarter of 2023 due to a decrease of $0.6 million in credit value adjustments on derivatives for the three months ended March 31, 2024 compared to the three months ended December 31, 2023.

For the three months ended March 31, 2024, merger-related expenses totaled $0.7 million, a decrease of $0.4 million, compared to $1.1 million for the three months ended December 31, 2023. The decrease is due to higher due diligence costs and professional fees incurred during the fourth quarter of 2023. The Company expects to incur additional merger-related expenses until the completion of the merger of equals.

Taxes other than income increased by $0.3 million to $0.5 million in the three months ended March 31, 2024 compared to $0.2 million in the three months ended December 31, 2023. The increase reflects the tax credits recognized on charitable contributions during the fourth quarter of 2023.

Income Taxes

The Company's effective tax rate for the first quarter of 2024 was 20.6% compared to 21.2% for the fourth quarter of 2023. The Company's effective tax rate for the three months ended March 31, 2024 is less than the 21% federal statutory rate primarily due to tax-exempt income, including interest earned on tax-exempt loans and securities and income from life insurance policies and tax credits, partially offset by the disallowed portion of interest expense against earnings in association with the Bank's tax-exempt investments under the Tax Equity and Fiscal Responsibility Act of 1982 ("TEFRA") and the impact of nondeductible merger-related costs. The nondeductible merger-related costs increased the effective tax rate by 1.2% for the first quarter of 2024. The effective tax rate for the fourth quarter of 2023 was higher due to an increase in state taxes in addition to the disallowed portion of interest expense against earnings in association with the Bank's tax-exempt investments under the TEFRA. The nondeductible merger-related costs increased the effective tax rate by 1.4% for the fourth quarter of 2023. The Company regularly analyzes its projected taxable income and makes adjustments to the provision for income taxes accordingly.

Capital

Shareholders’ equity totaled $271.7 million at March 31, 2024, an increase of $6.6 million from $265.1 million at December 31, 2023. The increase was primarily attributable to net income of $8.5 million, partially offset by dividends paid of $2.1 million. Other comprehensive losses totaled $0.2 million for the first quarter of 2024, which consisted of after-tax net unrealized losses on investment securities of $1.3 million partially offset by net unrealized gains on cash flow hedges of $1.1 million. The remaining activity is related to share-based compensation.

5

Tangible book value per share(1) increased to $23.47 per share at March 31, 2024 from $23.03 per share at December 31, 2023 due to the increase in shareholders' equity.

The Company's tangible common equity ratio decreased to 7.9% at March 31, 2024 from 8.0% at December 31, 2023, as total assets increased primarily due to the increase in deposits during the first quarter of 2024. The Company's total risk-based capital ratio was 13.4% at March 31, 2024 compared to 13.0% at December 31, 2023. The increase in the total risk-based capital ratio was partially due to the payoff of a commercial real estate loan on nonaccrual status, which reduced risk weighted assets by $20.0 million. The Company's Tier 1 leverage ratio was 8.9% at both March 31, 2024 and December 31, 2023. At March 31, 2024, all four capital ratios applicable to the Company were above regulatory minimum levels to be deemed “well capitalized” under current bank regulatory guidelines. The Company continues to believe that capital is adequate to support the risks inherent in the balance sheet, as well as growth requirements.

(1) Capital ratios are estimated, subject to regulatory filings. The Company elected the three-year phase in option for the day-one impact of ASU 2016-13 for current expected credit losses ("CECL") to regulatory capital. Beginning in 2023, the Company adjusted retained earnings, allowance for credit losses includable in tier 2 capital and the deferred tax assets from temporary differences in risk weighted assets by the permitted percentage of the day-one impact from adopting the new CECL standard.

Appendix A- Supplemental Reporting of Non-GAAP Measures and GAAP to Non-GAAP Reconciliations

Management believes providing certain other “non-GAAP” financial information will assist investors in their understanding of the effect on recent financial results from non-recurring charges.

As a result of acquisitions, the Company has intangible assets consisting of goodwill, core deposit and other intangible assets, which totaled $20.9 million and $21.1 million at March 31, 2024 and December 31, 2023, respectively. In addition, during the three ended March 31, 2024 and December 31, 2023, the Company incurred $0.7 million and $1.1 million in merger-related expenses, respectively.

Tangible book value per common share and the impact of the merger-related expenses on net income and associated ratios, as used by the Company in this earnings release, are determined by methods other than in accordance with U.S. Generally Accepted Accounting Principles ("GAAP"). While we believe this information is a useful supplement to GAAP based measures presented in this earnings release, readers are cautioned that this non-GAAP disclosure has limitations as an analytical tool, should not be viewed as a substitute for financial measures determined in accordance with GAAP, and should not be considered in isolation or as a substitute for analysis of our results and financial condition as reported under GAAP, nor are such measures necessarily comparable to non-GAAP performance measures that may be presented by other companies. This supplemental presentation should not be construed as an inference that our future results will be unaffected by similar adjustments to be determined in accordance with GAAP.

The following tables present the computation of each non-GAAP based measure:

Cautionary Note Regarding Forward-Looking Statements

This press release contains “forward-looking statements” within the meaning of Section 27A of the Securities Act and Section 21E of the Exchange Act. Forward-looking statements reflect the current views of the Company's management with respect to, among other things, future events and the Company's financial performance. These statements are often, but not always, made through the use of words or phrases such as “may,” “should,” “could,” “predict,” “potential,” “believe,” “will likely result,” “expect,” “continue,” “will,” “anticipate,” “seek,” “estimate,” “intend,” “plan,” “project,” “forecast,” “goal,” “target,” “would” and “outlook,” or the negative variations of those words or other comparable words of a future or forward-looking nature. These forward-looking statements are not historical facts, and are based on current expectations, estimates, predictions or projections about events or the Company's industry, management’s beliefs and certain assumptions made by management, many of which, by their nature, are inherently uncertain and beyond the Company's control. Accordingly, the Company cautions you that any such forward-looking statements are not guarantees of future performance and are subject to risks, assumptions and uncertainties that are difficult to predict. Although the Company believes that the expectations reflected in these forward-looking statements are reasonable as of the date made, actual results may prove to be materially different from the results expressed or implied by the forward-looking statements and there can be no assurances that the Company will achieve the desired level of new business development and new loans, growth in the balance sheet and fee-based revenue lines of business, successful merger and acquisition activity and cost savings initiatives and continued reductions in risk assets or mitigation of losses in the future. Factors which could cause the actual results of the Company's operations to differ materially from expectations include, but are not limited to: general economic conditions (including inflation and concerns about liquidity) on a national basis or in the local markets in which the Company operates; ineffectiveness of the Company's strategic growth plan due to changes in current or future market conditions; changes in interest rates; failure to complete the merger with Codorus Valley Bancorp, Inc. or unexpected delays related to the merger or either party's inability to satisfy closing conditions required to complete the merger; certain restrictions during the pendency of the proposed transactions with Codorus Valley Bancorp, Inc. that may impact the parties' abilities to pursue certain business opportunities or strategic transactions; the diversion of management's attention from ongoing business operations and opportunities; the effects of competition and how it may impact our community banking model, including industry consolidation and development of competing financial products and services; changes in consumer behavior due to changing political, business and economic conditions, or legislative or regulatory initiatives; changes in laws and regulations; changes in credit quality; inability to raise capital, if necessary, under favorable conditions; volatility in the securities markets; the demand for our products and services; deteriorating economic conditions; geopolitical tensions; operational risks including, but not limited to, cybersecurity incidents, fraud, natural disasters and future pandemics; expenses associated with litigation and legal proceedings; and other risks and uncertainties, including those detailed in our Annual Report on Form 10-K for the year ended December 31, 2023 under the sections titled “Risk Factors” and “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and in subsequent filings made with the Securities and Exchange Commission.

The foregoing list of factors is not exhaustive. If one or more events related to these or other risks or uncertainties materializes, or if the Company's underlying assumptions prove to be incorrect, actual results may differ materially from what the Company anticipates. Accordingly, you should not place undue reliance on any such forward-looking statements. Any forward-looking statement speaks only as of the date on which it is made, and the Company disclaims any obligation to publicly update or review any forward-looking statement, whether as a result of new information, future developments or otherwise. New risks and uncertainties arise from time to time, and it is not possible for the Company to predict those events or how they may affect it. In addition, the Company cannot assess the impact of each factor on its business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward-looking statements. All forward-looking statements, expressed or implied, included in this press release are expressly qualified in their entirety by this cautionary statement. This cautionary statement should also be considered in connection with any subsequent written or oral forward-looking statements that the Company or persons acting on the Company's behalf may issue.

22

The review period for subsequent events extends up to and includes the filing date of a public company’s financial statements, when filed with the Securities and Exchange Commission. Accordingly, the consolidated financial information presented in this announcement is subject to change. Annualized, pro forma, projected and estimated numbers in this document are used for illustrative purposes only and are not forecasts and may not reflect actual results.
