F.N.B. CORPORATION AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
(Unaudited)
September 30, 2024
The terms “FNB,” “the Corporation,” “we,” “us” and “our” throughout this Report mean F.N.B. Corporation and our consolidated subsidiaries, unless the context indicates that we refer only to the parent company, F.N.B. Corporation. When we refer to "FNBPA" in this Report, we mean our bank subsidiary, First National Bank of Pennsylvania, and its subsidiaries.
NATURE OF OPERATIONS
F.N.B. Corporation, headquartered in Pittsburgh, Pennsylvania, is a diversified financial services company operating in seven states and the District of Columbia. Our market coverage spans several major metropolitan areas including: Pittsburgh, Pennsylvania; Baltimore, Maryland; Cleveland, Ohio; Washington, D.C.; Charlotte, Raleigh, Durham and the Piedmont Triad (Winston-Salem, Greensboro and High Point) in North Carolina; and Charleston, South Carolina. As of September 30, 2024, we had 349 branches throughout Pennsylvania, Ohio, Maryland, West Virginia, North Carolina, South Carolina, Washington D.C. and Virginia.
We provide a full range of commercial banking, consumer banking and wealth management solutions through our subsidiary network which is led by our largest affiliate, FNBPA, founded in 1864. Commercial banking solutions include corporate banking, small business banking, investment real estate financing, government banking, business credit, capital markets and lease financing. Consumer banking provides a full line of consumer banking products and services, including deposit products, mortgage lending, consumer lending and a complete suite of mobile and online banking services. Wealth management services include asset management, private banking and insurance.
NOTE 1.    SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
Basis of Presentation
Our accompanying Consolidated Financial Statements and these Notes to Consolidated Financial Statements (unaudited) include subsidiaries in which we have a controlling financial interest. We own and operate FNBPA, First National Trust Company, First National Investment Services Company, LLC, F.N.B. Investment Advisors, Inc., First National Insurance Agency, LLC, Bank Capital Services, LLC, F.N.B. Capital Corporation, LLC and Waubank Securities, LLC, and include results for each of these entities in the accompanying Consolidated Financial Statements.
Companies in which we hold a controlling financial interest, or are a VIE in which we have the power to direct the activities of an entity that most significantly impact the entity’s economic performance and have an obligation to absorb losses or the right to receive benefits which could potentially be significant to the VIE, are consolidated. For a voting interest entity, a controlling financial interest is generally where we hold more than 50% of the outstanding voting shares. VIEs in which we do not hold the power to direct the activities of the entity that most significantly impact the entity’s economic performance or an obligation to absorb losses or the right to receive benefits which could potentially be significant to the VIE are not consolidated. Investments in companies that are not consolidated are accounted for using the equity method when we have the ability to exert significant influence or the cost method when we do not have the ability to exert significant influence. Investments in private investment partnerships that are accounted for under the equity method or the cost method are included in other assets and our proportional interest in the equity investments’ earnings are included in other non-interest income. Investment interests accounted for under the cost and equity methods are periodically evaluated for impairment.
The accompanying interim unaudited Consolidated Financial Statements include all adjustments that are necessary, in the opinion of management, to fairly reflect our financial position and results of operations in accordance with GAAP. All significant intercompany balances and transactions have been eliminated. Certain prior period amounts have been reclassified to the current period presentation. Such reclassifications had no impact on our net income and stockholders' equity. Events occurring subsequent to September 30, 2024 have been evaluated for potential recognition or disclosure in the Consolidated Financial Statements through the date of the filing of the Consolidated Financial Statements with the SEC.
Certain information and Note disclosures normally included in Consolidated Financial Statements prepared in accordance with GAAP have been condensed or omitted pursuant to the rules and regulations of the SEC. The interim operating results are not necessarily indicative of operating results we expect for the full year. These interim unaudited Consolidated Financial Statements should be read in conjunction with the audited Consolidated Financial Statements and Notes thereto included in our 2023 Annual Report on Form 10-K filed with the SEC on February 26, 2024.

Use of Estimates
Our accounting and reporting policies conform with GAAP. The preparation of financial statements in conformity with GAAP requires us to make estimates and assumptions that affect the amounts reported in the Consolidated Financial Statements and accompanying Notes to Consolidated Financial Statements (unaudited). Actual results could materially differ from those estimates. Material estimates that are particularly susceptible to significant changes include the ACL, fair value of financial instruments, goodwill and other intangible assets and income taxes and deferred tax assets, which are listed in the critical accounting estimates. For a detailed description of our significant accounting policies and critical accounting estimates, see Note 1, "Summary of Significant Accounting Policies" and the "Application of Critical Accounting Policies" section in the MD&A, both in our 2023 Annual Report on Form 10-K.
Adoption of New Accounting Standards
Effective January 1, 2024, we adopted the provision of ASU 2023-02, Accounting for Investments in Tax Credit Structures Using the Proportional Amortization Method, which permits reporting entities to make an accounting policy election to account for tax equity investments using the proportional amortization method if certain conditions are met. The election is to be made on a tax-credit-program-by-tax-credit-program basis and should be applied consistently to all investments within an elected tax credit program. Upon the adoption of ASU 2023-02, we elected to apply the proportional amortization method of accounting to our qualifying historic and new market tax credit investments. The proportional amortization method recognizes the amortized cost of the investment as a component of income tax expense on the consolidated statements of income and as a component of operating activities within other assets and other liabilities on the consolidated statements of cash flows. We historically applied proportional amortization to the majority of our LIHTC investments. LIHTCs that do not meet the requirements of the proportional amortization method are recognized using the equity method. See Note 8, "Variable Interest Entities" for additional information.
NOTE 2.    NEW ACCOUNTING STANDARDS
The following table summarizes accounting pronouncements issued by the FASB that we recently adopted or will be adopting in the future.
TABLE 2.1
StandardDescriptionFinancial Statements Impact
Income Taxes
ASU 2023-09, Income Taxes: Improvements to Income Tax Disclosures
This Update requires public business entities to disclose additional categories of information about federal, state, and foreign income taxes in the tabular rate reconciliation table. Additionally, entities must provide more details regarding reconciling items in some categories if the items are equal to or greater than a specified quantitative threshold.
This Update also requires all entities to annually disclose income taxes paid, net of refunds received, disaggregated by federal, state, and foreign taxes and further disaggregated by jurisdiction based on a specified quantitative threshold.
This Update is to be applied using a prospective method with an option to apply it retrospectively for each period presented and will be effective as of January 1, 2025. Early adoption is permitted.
We are currently evaluating the effect this Update will have on our consolidated financial statements, the related disclosures and our processes, systems, and controls related to disclosures.

StandardDescriptionFinancial Statements Impact
Segment Reporting
ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment DisclosureThis Update requires all public entities to disclose significant segment expenses and other segment items on an annual and interim basis and to provide in interim periods all disclosures about a reportable segment’s profit or loss and assets that are currently required in annual disclosures.
This Update is to be applied using a retrospective method to all prior periods presented and is effective for annual periods beginning on January 1, 2024, and will be effective for interim periods beginning on January 1, 2025. Early adoption is permitted.
We do not expect the adoption of this Update to materially impact our consolidated financial statements and we are currently evaluating the effect this Update will have on the related disclosures.
Tax Equity Investments
ASU 2023-02, Investments – Equity Method and Joint Ventures (Topic 323): Accounting for Investments in Tax Credit Structures Using the Proportional Amortization MethodThis Update expands the use of the proportional amortization method of accounting, previously only allowable for LIHTC investments, to equity investments in other tax credit structures that meet certain criteria.

The Update also removed the specialized guidance for LIHTC investments that are not accounted for using the proportional amortization method or equity method and require that those investments are accounted for using Topic 321 regarding equity investments.
This Update is to be applied using either a modified retrospective or a retrospective method and is effective as of January 1, 2024. Early adoption of this Update is permitted.

We adopted this Update on January 1, 2024 on a modified retrospective basis for tax credit programs that are eligible to apply proportional amortization. As a result, we recorded a reduction of $0.5 million in retained earnings for the cumulative effect of the adoption.
NOTE 3.    SECURITIES
The amortized cost and fair value of AFS debt securities are presented in the table below. There was no ACL associated with the AFS portfolio at September 30, 2024 and December 31, 2023. Accrued interest receivable on AFS debt securities totaled $14.1 million at September 30, 2024 and $9.6 million at December 31, 2023, and is excluded from the estimate of credit losses and assessed separately in other assets in the Consolidated Balance Sheets. Accordingly, we have excluded accrued interest receivable from both the fair value and amortized cost basis of AFS debt securities.
