F.N.B. CORPORATION AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

March 31, 2023

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 March 31, 2023, 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. Events occurring subsequent to March 31, 2023 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 2022 Annual Report on Form 10-K filed with the SEC on February 24, 2023.

10

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, income taxes and deferred tax assets and litigation reserves, 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 2022 Annual Report on Form 10-K.

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

Standard	Description	Financial Statements Impact
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 Method	This Update expands the use of the proportional amortization method of accounting, previously only allowable for LITHC 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 will be effective as of January 1, 2024. Early adoption of this Update is permitted. We are in the process of reviewing our existing tax equity investment portfolios and assessing the potential impact to our consolidated financial statements.
Troubled Debt Restructuring and Charge-offs
ASU 2022-02, Financial Instruments – Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures	This Update eliminates the recognition and measurement guidance on TDRs for creditors that have adopted ASC 326 and requires entities to apply loan refinancing and restructuring guidance to determine whether a modification results in a new loan or a continuation of an existing loan. The Update requires enhanced disclosures for certain loan modifications by creditors when a borrower is experiencing financial difficulty if the modification includes principal forgiveness, an interest rate reduction, an other-than-insignificant payment delay, a term extension, or a combination of those modification types. This Update also requires public business entities to present current-period gross write-offs by year of origination in their vintage disclosures.	This Update is to be applied using a prospective method. For the transition method related to TDRs, an entity has the option to apply a modified retrospective transition method. We adopted this Update on January 1, 2023. Adoption of this Update did not have a material impact on our consolidated financial statements.

NOTE 3.    MERGERS AND ACQUISITIONS

Howard Bancorp, Inc.

On January 22, 2022, we completed our acquisition of Howard, a bank holding company headquartered in Baltimore City, Maryland. The acquisition enhanced our presence in the Mid-Atlantic Region. Additionally, cost savings, efficiencies and other benefits were realized from the combined operations. On the acquisition date, Howard had assets with a net book value of approximately $2.4 billion, including $1.8 billion in both loans and deposits. The acquisition was valued at approximately $443 million and resulted in the issuance of 34,074,495 shares of our common stock in exchange for 18,930,329 shares of Howard common stock. We also acquired restricted stock units and the fully vested outstanding stock options of Howard.

This merger was accounted for in accordance with the acquisition method of accounting. Fair values for all assets and liabilities are presented in Table 3.1. Determining the fair value of assets and liabilities is a complex process involving significant judgment regarding estimates and assumptions used to calculate fair values. We have completed the review of valuations for the acquired assets and liabilities.

Goodwill related to the Howard acquisition was recorded in the Community Banking business segment and is not deductible for income tax purposes as the acquisition was accounted for as a tax-free exchange for tax purposes. We incurred merger expenses relating to the Howard acquisition of $28.6 million for the first three months of 2022. We did not record any merger expenses relating to the Howard acquisition in 2023.

Purchased loans and leases that reflect a more-than-insignificant deterioration of credit from origination are considered PCD. We consider various factors in connection with the identification of more-than-insignificant deterioration in credit, including but not limited to nonperforming status, delinquency, risk ratings, TDR classification, FICO scores and other qualitative factors that indicate deterioration in credit quality since origination. For PCD loans and leases, the initial estimate of expected credit losses is recognized in the ACL on the date of acquisition using the same methodology as other loans and leases held-for-investment. As part of the Howard acquisition, we acquired PCD loans and leases of $186.9 million. We established an ACL at acquisition of $10.0 million with a corresponding gross-up to the amortized cost of the PCD loans and leases. The non-credit discount on the PCD loans and leases was $5.4 million and the Day 1 fair value was $171.5 million. The initial provision expense for non-PCD loans associated with the Howard acquisition was $19.1 million.

We integrated the systems and the operating activities of Howard into FNB in February 2022. Due to that integration, it is impracticable to disclose the revenue from the Howard assets acquired and income before income taxes subsequent to the acquisition.

UB Bancorp

On December 9, 2022, we completed our acquisition of Union, a bank holding company based in Greenville, North Carolina. This acquisition further increases our presence in North Carolina and adds low-cost granular deposits which continue to be value accretive in the current economic environment. On the acquisition date, Union had assets with a net book value of approximately $1.1 billion, including $0.7 billion in loans and $1.0 billion in deposits. The acquisition was valued at approximately $126 million and resulted in the issuance of 9,672,691 shares of our common stock in exchange for 6,008,123 shares of Union common stock.

This merger was accounted for in accordance with the acquisition method of accounting. Preliminary fair values for all assets and liabilities are presented in Table 3.1. Determining the fair value of assets and liabilities is a complex process involving significant judgment regarding estimates and assumptions used to calculate fair values. Accordingly, the initial accounting for the merger is not complete.

We continue to analyze the valuations assigned to the acquired assets and assumed liabilities. Due to the complexity in valuing the loans and the significant amount of data inputs required, the valuation of the loans is not yet final. We are also assessing the valuation on deferred taxes. The valuation on acquired premises, core deposit intangibles and debt have been completed.

Goodwill related to the Union acquisition was recorded in the Community Banking business segment and is not deductible for income tax purposes as the acquisition was accounted for as a tax-free exchange for tax purposes. We incurred merger expenses relating to the Union acquisition of $2.1 million for the first three months of 2023. We recorded core deposit intangibles of $41 million which reflect the much higher cost of alternative funding given the higher interest rate environment at the time of acquisition.

12

Purchased loans and leases that reflect a more-than-insignificant deterioration of credit from origination are considered PCD. We consider various factors in connection with the identification of more-than-insignificant deterioration in credit, including but not limited to nonperforming status, delinquency, risk ratings, FICO scores and other qualitative factors that indicate deterioration in credit quality since origination. For PCD loans and leases, the initial estimate of expected credit losses is recognized in the ACL on the date of acquisition using the same methodology as other loans and leases held-for-investment. As part of the Union acquisition, we acquired PCD loans and leases of $36.9 million. We established an ACL at acquisition of $1.8 million with a corresponding gross-up to the amortized cost of the PCD loans and leases. The non-credit discount on the PCD loans and leases was $0.5 million and the Day 1 fair value was $34.7 million. The initial provision expense for non-PCD loans associated with the Union acquisition was $9.4 million.

We integrated the systems and the operating activities of Union in December 2022. Due to that integration, it is impracticable to disclose the revenue from the Union assets acquired and income before income taxes subsequent to the acquisition.

The following table summarizes the amounts recorded on the consolidated balance sheets as of the acquisition dates in conjunction with the Howard and Union acquisitions discussed above.

Accrued interest receivable on AFS debt securities totaled $8.9 million at both March 31, 2023 and December 31, 2022, 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 the amortized cost basis of AFS debt securities.

The amortized cost and fair value of HTM debt securities are presented in the table below. The ACL for the HTM portfolio was $0.32 million and $0.23 million at March 31, 2023 and December 31, 2022, respectively. Accrued interest receivable on HTM debt securities totaled $13.6 million and $14.0 million at March 31, 2023 and December 31, 2022, respectively, 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 the amortized cost basis of HTM debt securities.

There were no significant gross gains or gross losses realized on securities during the three months ended March 31, 2023 or 2022. Unrealized losses on the AFS and HTM portfolios are due to the increase in market interest rates with 84.9% of these securities backed or sponsored by the U.S. government as of March 31, 2023.

We evaluated the AFS debt securities that were in an unrealized loss position at March 31, 2023. Based on the credit ratings and implied government guarantee for these securities, we concluded the loss position is temporary and caused by the significant movement of interest rates since 2022 and does not reflect any expected credit losses. We do not intend to sell these

17

AFS debt securities and it is not more likely than not that we will be required to sell these securities before the recovery of their amortized cost basis.

Credit Quality Indicators

We use credit ratings and the most recent financial information to help evaluate the credit quality of our credit-related AFS and HTM securities portfolios. Management reviews the credit profile of each issuer on an annual basis, and more frequently as needed. Based on the nature of the issuers and current conditions, we have determined that securities backed by the UST, Fannie Mae, Freddie Mac, FHLB, Ginnie Mae, and the SBA have zero expected credit loss.

Our municipal bond portfolio, with a carrying amount of $1.1 billion as of March 31, 2023 is highly rated with an average rating of AA and 100% of the portfolio having an A or better rating. All of the securities in the municipal portfolio are general obligation bonds. Geographically, municipal bonds support our primary footprint as 60% of the securities are from municipalities located in the primary states within which we conduct business. The average holding size of the securities in the municipal bond portfolio is $2.5 million. In addition to the strong stand-alone ratings, 60% of the municipal bonds have some formal credit enhancement (e.g., insurance) that strengthens the creditworthiness of the bond.

The ACL on the HTM municipal bond portfolio is calculated on each bond using:

•The bond’s underlying credit rating, time to maturity and exposure amount;

•Credit enhancements that improve the bond’s credit rating (e.g., insurance); and

•Moody’s U.S. Bond Defaults and Recoveries, 1970-2021 study.

By using these components, we derive the expected credit loss on the HTM general obligation municipal bond portfolio. We further refine the expected credit loss by factoring in economic forecast data using our Commercial and Industrial Non-Manufacturing loan portfolio forecast adjustment as derived through our assessment of the loan portfolio as a proxy for our municipal bond portfolio.

Our corporate bond portfolio, with a carrying amount of $36.1 million as of March 31, 2023 primarily consists of subordinated debentures of banks within our footprint. The average holding size of the securities in the corporate bond portfolio is $2.4 million.

The ACL on the HTM corporate bond portfolio is calculated using:

•The bond’s credit rating, time to maturity and exposure amount;

•Moody’s Annual Default Study, 03/13/2023; and

•Most recent financial statements.

By using these components, we derive the expected credit loss on the HTM corporate bond portfolio. We further refine the expected credit loss by factoring in economic forecast data using our bank-wide loan portfolio forecast adjustment as derived through our assessment of the Bank's loan portfolio as a proxy for our corporate bond portfolio.

For the year-to-date periods ending March 31, 2023 and 2022, we had no significant provision expense and no charge-offs or recoveries. The ACL on the HTM portfolio was $0.32 million, consisting of $0.07 million relating to the municipal bond portfolio and $0.25 million relating to other debt securities, as of March 31, 2023, and $0.07 million relating to the municipal bond portfolio and $0.16 million relating to other debt securities as of December 31, 2022. The AFS securities portfolios did not have an ACL at March 31, 2023 or December 31, 2022 and there were no securities that were past due or on non-accrual at either date.

NOTE 5.    LOANS AND LEASES

Accrued interest receivable on loans and leases, which totaled $100.4 million at March 31, 2023 and $99.3 million at December 31, 2022, is excluded from the estimate of credit losses and assessed separately in other assets in the Consolidated Balance Sheets for both periods and not included in the following tables.

Loans and Leases by Portfolio Segment

Following is a summary of total loans and leases, net of unearned income:

Total consumer loans	11,161		10,965
Total loans and leases, net of unearned income	$	30,673	$	30,255

The remaining accretable discount included in the amortized cost of acquired loans was $54.5 million and $58.6 million at March 31, 2023 and December 31, 2022, respectively, which includes $10.1 million and $30.9 million established for Howard and Union, respectively, at the time of acquisition.

The loans and leases portfolio categories are comprised of the following types of loans, where in each case the LGD is dependent on the nature and value of the respective collateral:

•Commercial real estate includes both owner-occupied and non-owner-occupied loans secured by commercial properties where operational cash flows on owner-occupied properties or rents received by our borrowers from their tenant(s) on both a property and global basis are the primary default risk drivers, including rents paid by stand-alone business customers for owner-occupied properties;

•Commercial and industrial includes loans to businesses that are not secured by real estate where the borrower's leverage and cash flows from operations are the primary default risk drivers;

•Commercial leases consist of leases for new or used equipment where the borrower's cash flow from operations is the primary default risk driver;

•Other is comprised primarily of credit cards and mezzanine loans where the borrower's cash flow from operations is the primary default risk driver;

•Direct installment is comprised of fixed-rate, closed-end consumer loans for personal, family or household use, such as home equity loans and automobile loans where the primary default risk driver is the borrower's employment status and income;

•Residential mortgages consist of conventional and jumbo mortgage loans for 1-4 family properties where the primary default risk driver is the borrower's employment status and income;

•Indirect installment is comprised of loans originated by approved third parties and underwritten by us, primarily automobile loans where the primary default risk driver is the borrower's employment status and income; and

19

•Consumer lines of credit include home equity lines of credit and consumer lines of credit that are either unsecured or secured by collateral other than home equity where the primary default risk driver is the borrower's employment status and income.

The loans and leases portfolio consists principally of loans to individuals and small- and medium-sized businesses within our primary market in seven states and the District of Columbia. Our primary 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.

The following table shows occupancy information relating to commercial real estate loans:

Credit Quality

We monitor the credit quality of our loan portfolio using several performance measures based on payment activity and borrower performance. We use an internal risk rating assigned to a commercial loan or lease at origination, summarized below.

TABLE 5.3

Rating Category	Definition
Pass	in general, the condition of the borrower and the performance of the loan is satisfactory or better
Special Mention	in general, the condition of the borrower has deteriorated, requiring an increased level of monitoring
Substandard	in general, the condition of the borrower has significantly deteriorated and the performance of the loan could further deteriorate if deficiencies are not corrected
Doubtful	in general, the condition of the borrower has significantly deteriorated and the collection in full of both principal and interest is highly questionable or improbable

The use of these internally assigned credit quality categories within the commercial loan and lease portfolio permits our use of transition matrices to establish a basis which is then impacted by quantitative inputs from our econometric model forecasts over the R&S period. Our internal credit risk grading system is based on past experiences with similarly graded loans and leases and conforms to regulatory categories. In general, loan and lease risk ratings within each category are reviewed on an ongoing basis according to our policy for each class of loans and leases. Each quarter, we analyze the resulting ratings, as well as other external statistics and factors such as delinquency, to track the migration performance of the commercial loan and lease portfolio. Loans and leases within the Pass credit category or that migrate toward the Pass credit category generally have a lower risk of loss compared to loans and leases that migrate toward the Substandard or Doubtful credit categories. Accordingly, we apply higher risk factors to Substandard and Doubtful credit categories.

We use delinquency transition matrices within the consumer and other loan classes to establish the basis for the R&S forecast portion of the credit risk. Each month, management analyzes payment and volume activity, FICO scores and Debt-to-Income (DTI) scores and other external factors such as unemployment, to determine how consumer loans are performing.

The carrying value of residential-secured consumer OREO held as a result of obtaining physical possession upon completion of a foreclosure or through completion of a deed in lieu of foreclosure amounted to $1.0 million at March 31, 2023 and $1.1 million at December 31, 2022. The recorded investment of residential-secured consumer OREO for which formal foreclosure proceedings are in process at March 31, 2023 and December 31, 2022 totaled $14.4 million and $11.8 million, respectively.

Approximately $49.0 million of commercial loans are collateral dependent at March 31, 2023. Repayment is expected to be substantially through the operation or sale of the collateral on the loan. These loans are primarily secured by business assets or commercial real estate.

Loan Modifications

During the period, there are loans whose contractual terms have been modified in a manner that grants a concession to a borrower experiencing financial difficulties. These modifications typically result from loss mitigation activities and could include a term extension, interest rate reduction, principal forgiveness and other actions intended to minimize the economic loss and to avoid foreclosure or repossession of collateral. Accrued interest receivable on loan modifications totaled $0.02 million at March 31, 2023, and is excluded from the amortized cost of loan modifications in the tables below.

25

The following table shows the amortized cost basis at the end of the reporting period of the loans modified to borrowers experiencing financial difficulty, disaggregated by class of financing receivable, type of concession granted and the financial effect of the modifications made to borrowers experiencing financial difficulty:

TABLE 5.7

(dollars in millions)	Amortized Cost Basis		% of Total Class of Financing Receivable		Financial Effect

Residential mortgages	0.1		—		Multiple modifications were made with no material financial effect.
Total	$	0.7
Total Outstanding Modified	$	3.9

Some loan modifications may not ultimately result in the full collection of principal and interest, as modified, and may result in potential incremental losses which are factored into the ACL. There were no additional funds committed to borrowers whose loans were modified during the first three months of 2023.

Commercial loans over $1.0 million whose terms have been modified are generally placed on non-accrual, individually analyzed and measured based on the fair value of the underlying collateral. Our ACL includes specific reserves for commercial loans modified. There was $1.6 million and no specific reserve for commercial loans modified at March 31, 2023 and December 31, 2022, respectively, and pooled reserves for individual loans of $1.1 million and $1.1 million for those same periods, respectively, based on loan segment LGD. Upon default, the amount of the recorded investment of the modified loan balance in excess of the fair value of the collateral, less estimated selling costs, is generally considered a confirmed loss and is charged-off against the ACL.

All other classes of loans whose terms have been modified are pooled and measured based on the loan segment LGD. Our ACL included pooled reserves for these classes of loans of $3.7 million for March 31, 2023 and $3.8 million for December 31, 2022. Upon default of an individual loan, our charge-off policy is followed for that class of loan.

26

Following is a summary of loans modified in a manner that grants a concession to a borrower experiencing financial difficulties, by class, for which there was a payment default, excluding loans that have been paid off and/or sold. Default occurs when a loan is 90 days or more past due or in non-accrual and is within 12 months of restructuring.

NOTE 6.    ALLOWANCE FOR CREDIT LOSSES ON LOANS AND LEASES

The ACL is maintained for credit losses expected in the existing loan and lease portfolio and is presented as a reserve against loans and leases on the Consolidated Balance Sheets. Loan and lease losses are charged off against the ACL, with recoveries of amounts previously charged off credited to the ACL. Provisions for credit losses are charged to operations based on management’s periodic evaluation of the appropriate level of the ACL.

28

Following is a summary of changes in the ACL, by loan and lease class:

Following is a summary of changes in the AULC by portfolio segment:

TABLE 6.2

	Three Months Ended March 31,
	2023		2022
(in millions)
Balance at beginning of period	$	21.4	$	19.1
Provision for unfunded loan commitments and letters of credit:
Commercial portfolio	(0.9)		(0.3)
Consumer portfolio	—		—
Balance at end of period	$	20.5	$	18.8

The model used to calculate the ACL is dependent on the portfolio composition and credit quality, as well as historical experience, current conditions and forecasts of economic conditions and interest rates. Specifically, the following considerations are incorporated into the ACL calculation:

•a third-party macroeconomic forecast scenario;

•a 24-month R&S forecast period for macroeconomic factors with a reversion to the historical mean on a straight-line basis over a 12-month period; and

•the historical through-the-cycle mean was calculated using an expanded period to include a prior recessionary period.

At March 31, 2023 and December 31, 2022, we utilized a third-party consensus macroeconomic forecast reflecting the current and projected macroeconomic environment. For our ACL calculation at March 31, 2023, the macroeconomic variables that we utilized included, but were not limited to: (i) the purchase only Housing Price Index, which declines 2.5% over our R&S forecast period, (ii) a Commercial Real Estate Price Index, which declines 4.6% over our R&S forecast period, (iii) S&P Volatility, which decreases 39.7% in 2023 and 10.5% in 2024 and (iv) bankruptcies, which increase steadily over the R&S forecast period but average below historical levels. Macroeconomic variables that we utilized for our ACL calculation as of December 31, 2022 included, but were not limited to: (i) the purchase only Housing Price Index, which declines 3.7% over our R&S forecast period, (ii) a Commercial Real Estate Price Index, which declines 0.9% over our R&S forecast period, (iii) S&P Volatility, which decreases 41.0% in 2023 and 8.1% in 2024 and (iv) bankruptcies, which increase steadily over the R&S forecast period but average below historical levels.

The ACL on loans and leases of $403.4 million at March 31, 2023 increased $1.7 million, or 0.4%, from December 31, 2022. Our ending ACL coverage ratio at March 31, 2023 was 1.32%, compared to 1.33% at December 31, 2022. Total provision for credit losses for the three months ended March 31, 2023 was $14.1 million compared to $18.0 million for the same period of 2022. Provision was primarily due to loan growth, CECL-related model impacts from forecasted macroeconomic conditions and charge-off activity. The first quarter of 2023 reflected net charge-offs of $13.2 million, or 0.18% annualized of average total loans, compared to $1.9 million, or 0.03% annualized, in the first quarter of 2022.

NOTE 7.    LOAN SERVICING

Mortgage Loan Servicing

We retain the servicing rights on certain mortgage loans sold. The unpaid principal balance of mortgage loans serviced for others is listed below:

Balance at end of period	$	54.3	$	48.5
Fair value, beginning of period	$	68.6	$	46.0
Fair value, end of period	67.8		58.2

We had no valuation allowance for MSRs as of March 31, 2023 or December 31, 2022.

The fair value of MSRs is highly sensitive to changes in assumptions and is determined by estimating the present value of the asset’s future cash flows utilizing market-based prepayment rates, discount rates and other assumptions validated through comparison to trade information, industry surveys and the use of independent third-party valuations. Changes in prepayment speed assumptions have the most significant impact on the fair value of MSRs. Generally, as interest rates decline, mortgage loan prepayments accelerate due to increased refinance activity, which results in a decrease in the fair value of MSRs and as interest rates increase, mortgage loan prepayments decline, which results in an increase in the fair value of MSRs. Measurement of fair value is limited to the conditions existing and the assumptions utilized as of a particular point in time, and those assumptions may not be appropriate if they are applied at a different point in time.

31

Following is a summary of the sensitivity of the fair value of MSRs to changes in key assumptions:

TABLE 7.4

(dollars in millions)	March 31, 2023			December 31, 2022
Weighted average life (months)	95			96
Constant prepayment rate (annualized)	7.5		%	7.3		%
Discount rate	10.0		%	10.0		%

-0.50%	(3)			(3)
-1.00%	(7)			(6)
-2.00%	(18)			(15)

The sensitivity calculations above are hypothetical and should not be considered to be predictive of future performance. Changes in fair value based on adverse changes in assumptions generally cannot be extrapolated because the relationship of the changes in assumptions to fair value may not be linear. Also, in this table, the effects of an adverse variation in a particular assumption on the fair value of MSRs is calculated without changing any other assumptions, while, in reality, changes in one factor may result in changing another, which may magnify or contract the effect of the change.

NOTE 8.    LEASES

We have operating leases primarily for certain branches, office space, land and office equipment. We have finance leases for certain branches. Our operating leases expire at various dates through the year 2046 and generally include one or more options to renew. Our finance leases expire at various dates through the year 2051 and generally include one or more options to renew. The exercise of lease renewal options is at our sole discretion. As of March 31, 2023, we had operating lease right-of-use assets and operating lease liabilities of $135.1 million and $145.2 million, respectively. We have finance lease right-of-use assets and finance lease liabilities of $25.5 million and $26.2 million, respectively.

Our operating lease agreements do not contain any material residual value guarantees or material restrictive covenants. As of March 31, 2023, we have certain operating lease agreements, primarily for administrative office space, that have not yet commenced. At commencement, it is expected that these leases will add approximately $76.4 million in right-of-use assets and $97.8 million in other liabilities. These operating leases are currently expected to commence throughout the remainder of 2023 with lease terms of up to 21 years. These operating leases include the lease, with a related party, of the future new FNB headquarters building in Pittsburgh, Pennsylvania. The related party operating lease is accounted for in a manner consistent with all other leases on the basis of the legally enforceable terms and conditions of the lease and the related party represents a VIE for which we are not the primary beneficiary.

As a lessor we offer commercial leasing services to customers in need of new or used equipment primarily within our market areas of Pennsylvania, Ohio, Maryland, North Carolina, South Carolina and West Virginia. Additional information relating to commercial leasing is provided in Note 5, “Loans and Leases” in the Notes to Consolidated Financial Statements.

NOTE 9.     VARIABLE INTEREST ENTITIES

We evaluate our interest in certain entities to determine if these entities meet the definition of a VIE and whether we are the primary beneficiary and required to consolidate the entity based on the variable interest we held both at inception and when there is a change in circumstances that requires a reconsideration.

Unconsolidated VIEs

The following table provides a summary of the assets and liabilities included in our Consolidated Financial Statements, as well as the maximum exposure to losses, associated with our interests related to VIEs for which we hold an interest, but are not the primary beneficiary, at March 31, 2023 and December 31, 2022.

Trust-Preferred Securities

We have certain wholly-owned trusts whose assets, liabilities, equity, income and expenses are not included within our Consolidated Financial Statements. These trusts have been formed for the sole purpose of issuing TPS, from which the proceeds are then invested in our junior subordinated debentures, which are reflected in our Consolidated Balance Sheets as subordinated notes. The TPS are the obligations of the trusts, and as such, are not consolidated within our Consolidated Financial Statements. For additional information relating to our TPS, see Note 10, “Borrowings” in the Notes to Consolidated Financial Statements.

Each issue of the junior subordinated debentures has an interest rate equal to the corresponding TPS distribution rate. We have the right to defer payment of interest on the debentures at any time, or from time-to-time for a period not exceeding five years provided that no extension period may extend beyond the stated maturity of the related debentures. During any such extension period, distributions to the TPS will also be deferred and our ability to pay dividends on our common stock will be restricted. Periodic cash payments and payments upon liquidation or redemption with respect to TPS are guaranteed by us to the extent of funds held by the trusts. The guarantee ranks subordinate and junior in right of payment to all of our indebtedness to the same extent as the junior subordinated debt. The guarantee does not place a limitation on the amount of additional indebtedness that may be incurred by us.

Affordable Housing Tax Credit Partnerships

We make equity investments as a limited partner in various partnerships that sponsor affordable housing projects utilizing the LIHTC pursuant to Section 42 of the Internal Revenue Code. The purpose of these investments is to support initiatives

34

associated with the Community Reinvestment Act while earning a satisfactory return. The activities of these LIHTC partnerships include the development and operation of multi-family housing that is leased to qualifying residential tenants. These partnerships are generally located in communities where we have a banking presence and meet the definition of a VIE; however, we are not the primary beneficiary of the entities, as the general partner or managing member has both the power to direct the activities that most significantly impact the economic performance of the entities and the obligation to absorb losses beyond our own equity investment. We record our investment in LIHTC partnerships as a component of other assets and use the proportional amortization method to account for our investments in LIHTC partnerships. Amortization related to our LIHTC investments is recorded on a net basis as a component of the provision for income taxes on the Consolidated Statements of Income.

The following table presents the balances of our affordable housing tax credit investments and related unfunded commitments:

NOTE 10.    BORROWINGS

Following is a summary of short-term borrowings:

TABLE 10.1

(in millions)	March 31, 2023		December 31, 2022
Securities sold under repurchase agreements	$	255	$	317
Federal Home Loan Bank advances	1,600		930
Federal funds purchased	175		—
Subordinated notes	119		125
Total short-term borrowings	$	2,149	$	1,372

Borrowings with original maturities of one year or less are classified as short-term. Securities sold under repurchase agreements are comprised of customer repurchase agreements, which are sweep accounts with next-day maturities utilized by larger commercial customers to earn interest on their funds. Securities are pledged to these customers in an amount at least equal to

35

the outstanding balance. Of the total short-term FHLB advances, 9.4% had overnight maturities as of March 31, 2023. We did not have any short-term FHLB advances with overnight maturities as of December 31, 2022. At March 31, 2023, $800.0 million, or 50.0%, of the short-term FHLB advances were swapped to fixed rates with various maturities through 2024. This compares to $930.0 million, or 100.0%, as of December 31, 2022.

Following is a summary of long-term borrowings:

TABLE 10.2

Subordinated notes	75		70
Junior subordinated debt	72		72
Other subordinated debt	303		303
Total long-term borrowings	$	1,298	$	1,093

During the third quarter of 2022, we completed a debt offering in which we issued $350 million aggregate principal amount of 5.150% fixed-rate senior notes due in 2025. The net proceeds of the debt offering after deducting underwriting discounts and commissions and offering costs were $347.4 million. These proceeds were used for general corporate purposes, which included the repayment of $300 million in 2.200% Senior Notes that matured in February 2023, and may also include investments at the holding company level, capital to support the growth of FNBPA and refinancing of outstanding indebtedness.

During 2022, we assumed $25 million of other subordinated debt and $5 million of junior subordinated debt from the Howard acquisition and $31 million of other subordinated debt from the Union acquisition. Those additions are reflected in the balances above and in the tables below.

Our banking affiliate has available credit with the FHLB of $10.5 billion, of which $2.1 billion was utilized and included in short-term and long-term borrowings and $590.0 million was utilized for a letter of credit for pledging of public funds as of March 31, 2023. These advances are secured by loans collateralized by residential mortgages, home equity lines of credit, commercial real estate and FHLB stock and the short-term borrowings are scheduled to mature in various amounts periodically during 2023 while the long-term borrowings are scheduled to mature in 2025. Effective interest rates paid on the long-term FHLB advances held during 2023 ranged from 4.55% to 4.69% for the three months ended March 31, 2023. There were no long-term FHLB borrowings during the first three months of 2022, or as of December 31, 2022.

(5) Assumed from an acquisition and adjusted to fair value at the time of acquisition.

(6) After deducting underwriting discounts and commissions and offering costs. For the debt assumed from acquisitions, this is the fair value of the debt at the time of the acquisition.

The junior subordinated debt is comprised of the debt securities issued by FNB, or companies we acquired, in relation to our four unconsolidated subsidiary trusts (collectively, the Trusts), which are unconsolidated VIEs, and are included on the Consolidated Balance Sheets in long-term borrowings. Since third-party investors are the primary beneficiaries, the Trusts are not consolidated in our Financial Statements. We record the distributions on the junior subordinated debt issued to the Trusts as interest expense.

The following table provides information relating to the Trusts as of March 31, 2023:

NOTE 11.    DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES

We are exposed to certain risks arising from both our business operations and economic conditions. We principally manage our exposures to a wide variety of business and operational risks through management of our core business activities. We manage economic risks, including interest rate risk, primarily by managing the amount, source, and duration of our assets and liabilities, and through the use of derivative instruments. Derivative instruments are used to reduce the effects that changes in interest rates may have on net income and cash flows. We also use derivative instruments to facilitate transactions on behalf of our customers.

All derivatives are carried on the Consolidated Balance Sheets at fair value and do not take into account the effects of master netting arrangements we have with other financial institutions. Credit risk is included in the determination of the estimated fair value of derivatives. Derivative assets are reported in the Consolidated Balance Sheets in other assets and derivative liabilities are reported in other liabilities. Changes in fair value are recognized in earnings except for certain changes related to derivative instruments designated as part of a cash flow hedging relationship, which are recognized in other comprehensive income.

The following table presents notional amounts and gross fair values of our derivative assets and derivative liabilities which are not offset in the Consolidated Balance Sheets:

TABLE 11.1

Total	$	13,759	$	83	$	324	$	13,718	$	96	$	411

Certain derivative exchanges have enacted a rule change which in effect results in the legal characterization of variation margin payments for certain derivative contracts as settlement of the derivatives mark-to-market exposure and not collateral. Accordingly, we have changed our reporting of certain derivatives to record variation margin on trades cleared through these exchanges as settled.  The daily settlement of the derivative exposure does not change or reset the contractual terms of the instrument.

We adopted Reference Rate Reform (RRR) on October 1, 2020, and the guidance will be followed until the Update terminates on December 31, 2024. As of October 16, 2020, we changed our valuation methodology to reflect changes made by central clearinghouses that changed the discounting methodology and interest calculation of cash migration from overnight index swap (OIS) to SOFR for U.S. dollar cleared interest rate swaps to better reflect prices obtainable in the markets in which we transact. Certain of these valuation methodology changes were applied to eligible hedging relationships. Accordingly, we have updated our hedge documentation to reflect the election of certain expedients and exceptions related to our cash flow hedging programs. The change in valuation methodology was applied prospectively as a change in accounting estimate and did not have a material impact on our consolidated financial position or results of operations.

38

Derivatives Designated as Hedging Instruments under GAAP

Interest Rate Contracts. We entered into interest rate derivative agreements to modify the interest rate characteristics of certain commercial loans and certain of our FHLB advances from variable rate to fixed rate in order to reduce the impact of changes in future cash flows due to market interest rate changes. These agreements are designated as cash flow hedges, hedging the exposure to variability in expected future cash flows. The derivative’s gain or loss, including any ineffectiveness, is initially reported as a component of other comprehensive income and subsequently reclassified into earnings in the same line item associated with the forecasted transaction when the forecasted transaction affects earnings.

The following table shows amounts reclassified from AOCI:

TABLE 11.2

	Amount of Gain (Loss) Recognized in OCI on Derivatives				Location of Gain (Loss) Reclassified from AOCI into Income	Amount of Gain (Loss) Reclassified from AOCI into Income

The effects of cash flow hedging:
Gain (loss) on cash flow hedging relationships:
Interest rate contracts:
Amount of gain (loss) reclassified from AOCI into net income	(10)		6		2		(4)

As of March 31, 2023, the maximum length of time over which forecasted interest cash flows are hedged is 3.1 years. In the twelve months that follow March 31, 2023, we expect to reclassify from the amount currently reported in AOCI net derivative losses of $23.9 million ($18.5 million net of tax), in association with interest on the hedged loans and FHLB advances. This amount could differ from amounts actually recognized due to changes in interest rates, hedge de-designations, and the addition of other hedges subsequent to March 31, 2023.

There were no components of derivative gains or losses excluded from the assessment of hedge effectiveness related to these cash flow hedges. Also, during the three months ended March 31, 2023 and 2022, there were no gains or losses from cash flow hedge derivatives reclassified to earnings because it became probable that the original forecasted transactions would not occur.

39

Derivatives Not Designated as Hedging Instruments under GAAP

A description of interest rate swaps, interest rate lock commitments, forward delivery commitments and credit risk contracts can be found in Note 16, "Derivative Instruments and Hedging Activities" in the Consolidated Financial Statements included in our 2022 Annual Report on Form 10-K filed with the SEC on February 24, 2023.

Interest rate swap agreements with loan customers and with the offsetting counterparties are reported at fair value in other assets and other liabilities on the Consolidated Balance Sheets with any resulting gain or loss recorded in current period earnings as other income or other expense.

Risk participation agreements sold with notional amounts totaling $483.7 million as of March 31, 2023 have remaining terms ranging from one month to eighteen years. Under these agreements, our maximum exposure assuming a customer defaults on their obligation to perform under certain derivative swap contracts with third parties would be $0.2 million at March 31, 2023 and $0.1 million at December 31, 2022. The fair values of risk participation agreements purchased and sold were $0.1 million and $0.2 million, respectively, at March 31, 2023 and $0.1 million and $0.1 million, respectively at December 31, 2022.

The following table presents the effect of certain derivative financial instruments on the Consolidated Statements of Income:

Counterparty Credit Risk

We are party to master netting arrangements with most of our swap derivative dealer counterparties. Collateral, usually marketable securities and/or cash, is exchanged between FNB and our counterparties, and is generally subject to thresholds and transfer minimums. For swap transactions that require central clearing, we post cash and securities to our clearing agency. Collateral positions are settled or valued daily, and adjustments to amounts received and pledged by us are made as appropriate to maintain proper collateralization for these transactions.

Certain master netting agreements contain provisions that, if violated, could cause the counterparties to request immediate settlement or demand full collateralization under the derivative instrument. If we had breached our agreements with our derivative counterparties we would be required to settle our obligations under the agreements at the termination value and would be required to pay nothing as of March 31, 2023 and an additional $0.1 million as of December 31, 2022, in excess of amounts previously posted as collateral with the respective counterparty.

NOTE 12.    COMMITMENTS, CREDIT RISK AND CONTINGENCIES

We have commitments to extend credit and standby letters of credit that involve certain elements of credit risk in excess of the amount stated in the Consolidated Balance Sheets. Our exposure to credit loss in the event of non-performance by the customer is represented by the contractual amount of those instruments. The credit risk associated with commitments to extend credit and standby letters of credit is essentially the same as that involved in extending loans and leases to customers and is subject to normal credit policies. Since many of these commitments expire without being drawn upon, the total commitment amounts do not necessarily represent future cash flow requirements.

Following is a summary of off-balance sheet credit risk information:

TABLE 12.1

(in millions)	March 31, 2023		December 31, 2022
Commitments to extend credit	$	13,009	$	13,250
Standby letters of credit	229		207

At March 31, 2023, funding of 73.7% of the commitments to extend credit was dependent on the financial condition of the customer. We have the ability to withdraw such commitments at our discretion. Commitments generally have fixed expiration

41

dates or other termination clauses and may require payment of a fee. Based on management’s credit evaluation of the customer, collateral may be deemed necessary. Collateral requirements vary and may include accounts receivable, inventory, property, plant and equipment and income-producing commercial properties.

Standby letters of credit are conditional commitments issued by us that may require payment at a future date. The credit risk involved in issuing letters of credit is actively monitored through review of the historical performance of our portfolios.

Our AULC for commitments that are not unconditionally cancellable, which is included in other liabilities on the Consolidated Balance Sheets, was $20.5 million at March 31, 2023 and $21.4 million at December 31, 2022. Additional information relating to the AULC is provided in Note 6, "Allowance for Credit Losses on Loans and Leases" in the Notes to Consolidated Financial Statements.

In addition to the above commitments, subordinated notes issued by FNB Financial Services, LP, a wholly-owned finance subsidiary, are fully and unconditionally guaranteed by FNB. These subordinated notes are included in the summaries of short-term borrowings and long-term borrowings in Note 10, “Borrowings” in the Notes to Consolidated Financial Statements.

Other Legal Proceedings

In the ordinary course of business, we may assert claims in legal proceedings against another party or parties, and we are routinely named as defendants in, or made parties to, pending and potential legal actions. Also, as regulated entities, we are subject to governmental and regulatory examinations, information-gathering requests, and may be subject to investigations and proceedings (both formal and informal). Such threatened claims, litigation, investigations, regulatory and administrative proceedings typically entail matters that are considered incidental to the normal conduct of business. Claims for significant monetary damages may be asserted in many of these types of legal actions, while claims for disgorgement, reimbursement, restitution, penalties and/or other remedial actions or sanctions may be sought in regulatory matters. In these instances, if we determine that we have meritorious defenses, we will engage in an aggressive defense. However, if management determines, in consultation with counsel, that settlement of a matter is in the best interest of FNB and our shareholders, we may do so. It is inherently difficult to predict the eventual outcomes of such matters given their complexity and the particular facts and circumstances at issue in each of these matters. However, on the basis of current knowledge and understanding, and advice of counsel, we do not believe that judgments, sanctions, settlement resolutions, regulatory actions, investigations, settlements or orders, if any, that have arisen or may arise from these matters (either individually or in the aggregate, after giving effect to applicable reserves and insurance coverage) will have a material adverse effect on our financial position or liquidity, although they could potentially have a material effect on net income in a given period.

In view of the inherent unpredictability of outcomes in litigation and governmental and regulatory matters, particularly where (i) the damages sought are indeterminate, (ii) the proceedings are in the early stages, or (iii) the matters involve novel legal theories or a large number of parties, as a matter of course, there is considerable uncertainty surrounding the timing or ultimate resolution of litigation and governmental and regulatory matters, including a possible eventual loss, fine, restitution, penalty, business or adverse reputational impact, if any, associated with each such matter. In accordance with applicable accounting guidance, we establish accruals for litigation and governmental and regulatory matters when those matters proceed to a stage where they present loss contingencies that are both probable and reasonably estimable. In such cases, there may be a possible exposure to loss in excess of any amounts accrued. We will continue to monitor such matters, including ongoing reviews, examinations, and investigations by banking regulatory agencies and other government authorities, for developments that could affect the amount of the accrual, and will adjust the accrual amount as appropriate. If the loss contingency in question is not both probable and reasonably estimable, we do not establish an accrual and the matter will continue to be monitored for any developments that would make the loss contingency both probable and reasonably estimable. We believe that our accruals for legal proceedings are appropriate and, in the aggregate, are not material to our consolidated financial position, although future accruals could have a material effect on net income in a given period.

NOTE 13.    STOCK INCENTIVE PLANS

Restricted Stock

We issue restricted stock awards to key employees under our Incentive Compensation Plan (Plan). We issue time-based awards and performance-based awards under this Plan, both of which are based on a three-year vesting period. The grant date fair value of the time-based awards is equal to the price of our common stock on the grant date. The fair value of the performance-based awards is based on a Monte-Carlo simulation valuation of our common stock as of the grant date. The assumptions used for this valuation include stock price volatility, risk-free interest rate and dividend yield. We granted 470,173 and 495,844 restricted stock units during the three months ended March 31, 2023 and 2022, respectively, including 282,106 and 297,508

42

performance-based restricted stock units during those same periods, respectively. As of March 31, 2023, we had available up to 8,680,887 shares of common stock to issue under this Plan, including 7,397,956 shares registered during the second quarter of 2022.

The unvested restricted stock unit awards are eligible to receive cash dividends or dividend equivalents which are ultimately used to purchase additional shares of stock and are subject to forfeiture if the requisite service period is not completed or the specified performance criteria are not met. These awards are subject to certain accelerated vesting provisions upon retirement, death, disability or in the event of a change of control as defined in the award agreements.

The following table summarizes the activity relating to restricted stock units during the periods indicated:

Stock Options

All outstanding stock options were assumed from acquisitions and are fully vested. Upon consummation of our acquisitions, all outstanding stock options issued by the acquired companies were converted into equivalent FNB stock options. We issue shares of treasury stock or authorized but unissued shares to satisfy stock options exercised.

As of March 31, 2023, we had 110,222 stock options outstanding and exercisable at a weighted average exercise price per share of $9.86, compared to 176,602 stock options outstanding and exercisable at a weighted average exercise price per share of $8.96 as of March 31, 2022.

The intrinsic value of outstanding and exercisable stock options at March 31, 2023 was $0.2 million. The aggregate intrinsic value represents the amount by which the fair value of underlying stock exceeds the option exercise price.

Income tax expense was higher in 2023 due to higher pre-tax earnings as we had merger-related expenses from the Howard and Union acquisitions in 2022. The decrease in the effective tax rate for the three months ended March 31, 2023 compared to 2022 was primarily driven by higher deduction levels from employee stock compensation vesting.

Deferred Income Taxes

Deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and tax purposes. Deferred tax assets and liabilities are measured based on the enacted tax rates that will apply in the years in which the temporary differences are expected to be recovered or paid. Net deferred tax assets were $133.7 million and $147.7 million at March 31, 2023 and December 31, 2022, respectively.

The amounts reclassified from AOCI related to debt securities AFS are included in net securities gains on the Consolidated Statements of Income, while the amounts reclassified from AOCI related to derivative instruments in cash flow hedge programs are generally included in interest income on loans and leases on the Consolidated Statements of Income. The tax (benefit) expense amounts reclassified from AOCI in connection with the debt securities AFS and derivative instruments reclassifications are included in income taxes on the Consolidated Statements of Income.

NOTE 16.    EARNINGS PER COMMON SHARE

Basic earnings per common share is calculated by dividing net income available to common stockholders by the weighted average number of shares of common stock outstanding net of unvested shares of restricted stock.

Diluted earnings per common share is calculated by dividing net income available to common stockholders by the weighted average number of shares of common stock outstanding, adjusted for the dilutive effect of potential common shares issuable for stock options and restricted shares, as calculated using the treasury stock method. Adjustments to the weighted average number of shares of common stock outstanding are made only when such adjustments dilute earnings per common share.

The following table sets forth the computation of basic and diluted earnings per common share:

NOTE 19.    FAIR VALUE MEASUREMENTS

Refer to Note 26 "Fair Value Measurements" to the Consolidated Financial Statements included in our 2022 Annual Report on Form 10-K filed with the SEC on February 24, 2023 for a description of additional valuation methodologies for assets and liabilities measured at fair value on a recurring and non-recurring basis.

The following table presents the balances of assets and liabilities measured at fair value on a recurring basis:

We review fair value hierarchy classifications on a quarterly basis. Changes in the observability of the valuation attributes may result in reclassification of certain financial assets or liabilities. Such reclassifications are reported as transfers in/out of Level 3 at fair value at the beginning of the period in which the changes occur. There were no transfers of assets or liabilities between the hierarchy levels during the first three months of 2023 or 2022.

From time to time, we measure certain assets at fair value on a non-recurring basis. These adjustments to fair value usually result from the application of the lower of cost or fair value accounting or write-downs of individual assets. Valuation methodologies used to measure these fair value adjustments were described in Note 26, "Fair Value Measurements" to the Consolidated Financial Statements included in 2022 Annual Report on Form 10-K. For assets measured at fair value on a non-recurring basis still held at the Balance Sheet date, the following table provides the hierarchy level and the fair value of the related assets or portfolios:

TABLE 19.3

(in millions)	Level 1		Level 2		Level 3		Total

Collateral dependent loans	$	—	$	—	$	34	$	34
Other assets - SBA servicing asset	—		—		2		2

The fair value amounts for collateral dependent loans and OREO in the table above were estimated at a date during the three months or twelve months ended March 31, 2023 and December 31, 2022, respectively. Consequently, the fair value information presented is not necessarily as of the period’s end. Collateral dependent loans measured or re-measured at fair value on a non-recurring basis during the three months ended March 31, 2023 had a carrying amount of $29.9 million, which includes an allocated ACL of $8.8 million. The ACL includes a credit to the provision applicable to the current period fair value measurements of $6.9 million, which was included in provision for credit losses for the three months ended March 31, 2023.

SBA servicing assets measured at fair value on a non-recurring basis had a carrying value of $1.9 million. During 2023, the valuation allowance decreased $0.3 million to $1.3 million as of March 31, 2023, down from $1.6 million at December 31, 2022, which is reflected in the year-to-date provision expense.

OREO measured at fair value on a non-recurring basis during 2023 had a carrying amount of $0.6 million, which included a valuation allowance of $0.3 million, as of March 31, 2023. The valuation allowance includes a loss of $0.4 million, which was included in earnings for the three months ended March 31, 2023.

Fair Value of Financial Instruments

Refer to Note 26, "Fair Value Measurements" to the Consolidated Financial Statements included in our 2022 Annual Report on Form 10-K filed with the SEC on February 24, 2023 for a description of methods and assumptions that were used to estimate the fair value of each financial instrument.

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

MD&A represents an overview of and highlights material changes to our financial condition and consolidated results of operations at and for the three-month periods ended March 31, 2023 and 2022. This MD&A should be read in conjunction with the Consolidated Financial Statements and Notes thereto contained herein and our 2022 Annual Report on Form 10-K filed with the SEC on February 24, 2023. Our results of operations for the three months ended March 31, 2023 are not necessarily indicative of results expected for the full year.

CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING INFORMATION

This Report may contain statements regarding our outlook for earnings, revenues, expenses, tax rates, capital and liquidity levels and ratios, asset quality levels, financial position and other matters regarding or affecting our current or future business and operations. These statements can be considered “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995. These forward-looking statements involve various assumptions, risks and uncertainties which can change over time. Actual results or future events may be different from those anticipated in our forward-looking statements and may not align with historical performance and events. As forward-looking statements involve significant risks and uncertainties, caution should be exercised against placing undue reliance upon such statements. Forward-looking statements are typically identified by words such as "believe," "plan," "expect," "anticipate," "intend," "outlook," "estimate," "forecast," "will," "should," "project," "goal," and other similar words and expressions. We do not assume any duty to update forward-looking statements, except as required by federal securities laws.

Our forward-looking statements are subject to the following principal risks and uncertainties:

•Our business, financial results and balance sheet values are affected by business, economic and political circumstances, including, but not limited to: (i) developments with respect to the U.S. and global financial markets; (ii) supervision, regulation, enforcement and other actions by several governmental agencies, including the FRB, FDIC, Financial Stability Oversight Council (FSOC), DOJ, CFPB, UST, OCC and Department of Housing and Urban Development (HUD), state attorney generals and other governmental agencies whose actions may affect, among other things, our consumer and mortgage lending and deposit practices, capital structure, investment practices, dividend policy, annual FDIC insurance premium assessment and growth, money supply, market interest rates or otherwise affect business activities of the financial services industry; (iii) a slowing of the U.S. economy in general and regional and local economies within our market area; (iv) inflation concerns; (v) the impacts of tariffs or other trade policies of the U.S. or its global trading partners; and (vi) the sociopolitical environment in the U.S.

•Business and operating results are affected by our ability to identify and effectively manage risks inherent in our businesses, including, where appropriate, through effective use of systems and controls, third-party insurance, derivatives, and capital management techniques, and to meet evolving regulatory capital and liquidity standards.

•Competition can have an impact on customer acquisition, growth and retention, and on credit spreads, deposit gathering and product pricing, which can affect market share, loans, deposits and revenues. Our ability to anticipate, react quickly and continue to respond to technological changes and potential additional novel coronavirus disease of 2019 (COVID-19) challenges can also impact our ability to respond to customer needs and meet competitive demands.

•Business and operating results can also be affected by widespread natural and other disasters, pandemics and post-pandemic return to normalcy, global events, including the Ukraine-Russia conflict, shortages of labor, supply chain disruptions and shipping delays, terrorist activities, system failures, security breaches, significant political events, cyber-attacks or international hostilities through impacts on the economy and financial markets generally, or on us or our counterparties specifically.

•Legal, regulatory and accounting developments could have an impact on our ability to operate and grow our businesses, financial condition, results of operations, competitive position, and reputation. Reputational impacts could affect matters such as business generation and retention, liquidity, funding, and the ability to attract and retain talent. These developments could include:

◦Policies and priorities of the current U.S. presidential administration, including legislative and regulatory reforms, more aggressive approaches to supervisory or enforcement priorities with consumer and anti-discrimination lending laws by the federal banking agencies and DOJ, changes affecting oversight of the financial services industry, regulatory obligations or restrictions, consumer protection, taxes, employee benefits, compensation practices, pension, bankruptcy and other industry aspects, and changes in accounting policies and principles.

52

◦Changes to regulations or accounting standards governing bank capital requirements, loan loss reserves and liquidity standards.

◦Changes in monetary and fiscal policies, including interest rate policies and strategies of the FOMC.

◦Unfavorable resolution of legal proceedings or other claims and regulatory and other governmental investigations or inquiries. These matters may result in monetary judgments or settlements, enforcement actions or other remedies, including fines, penalties, restitution or alterations in our business practices, and in additional expenses and collateral costs, and may cause reputational harm to FNB.

◦Results of the regulatory examination and supervision process, including our failure to satisfy requirements imposed by the federal bank regulatory agencies or other governmental agencies.

◦Business and operating results are affected by our ability to effectively identify and manage risks inherent in our businesses, including, where appropriate, through effective use of policies, processes, systems and controls, third-party insurance, derivatives, and capital and liquidity management techniques.

◦The impact on our financial condition, results of operations, financial disclosures and future business strategies related to the impact on the ACL due to changes in forecasted macroeconomic conditions as a result of applying the “current expected credit loss” accounting standard, or CECL.

◦A failure or disruption in or breach of our operational or security systems or infrastructure, or those of third parties, including as a result of cyber-attacks or campaigns.

•The COVID-19 pandemic and the federal, state, and local regulatory and governmental actions implemented in response to COVID-19 have resulted in increased volatility of the financial markets and national and local economic conditions, supply chain challenges, rising inflationary pressures, increased levels of unemployment and business failures, and the potential to have a material impact on, among other things, our business, financial condition, results of operations, liquidity, or on our management, employees, customers and critical vendors and suppliers. In view of the many unknowns associated with the COVID-19 pandemic, our forward-looking statements continue to be subject to various conditions that may be substantially different in the future than what we are currently experiencing or expecting, including, but not limited to, challenging headwinds for the U.S. economy and labor market and the possible change in commercial and consumer customer fundamentals, expectations and sentiments. As a result of the COVID-19 impact, including uncertainty regarding the potential impact of continuing variant mutations of the virus, U.S. government responsive measures to manage it or provide financial relief, the uncertainty regarding its duration and the success of vaccination efforts, it is possible the pandemic may have a material adverse impact on our business, operations and financial performance.

The risks identified here are not exclusive or the types of risks we may confront and actual results may differ materially from those expressed or implied as a result of these risks and uncertainties, including, but not limited to, the risk factors and other uncertainties described under Item 1A. Risk Factors and the Risk Management sections of our 2022 Annual Report on Form 10-K, our subsequent 2023 Quarterly Reports on Form 10-Q (including the risk factors and risk management discussions) and our other 2023 filings with the SEC, which are available on our corporate website at https://www.fnb-online.com/about-us/investor-information/reports-and-filings or the SEC's website at www.sec.gov. More specifically, our forward-looking statements may be subject to the evolving risks and uncertainties related to the COVID-19 pandemic and its macro-economic impact and the resulting governmental, business and societal responses to it. We have included our web address as an inactive textual reference only. Information on our website is not part of our SEC filings.

APPLICATION OF CRITICAL ACCOUNTING POLICIES

A description of our critical accounting policies is included in the MD&A section of our 2022 Annual Report on Form 10-K filed with the SEC on February 24, 2023 under the heading “Application of Critical Accounting Policies”. There have been no significant changes in critical accounting policies or the assumptions and judgments utilized in applying these policies since December 31, 2022.

USE OF NON-GAAP FINANCIAL MEASURES AND KEY PERFORMANCE INDICATORS

To supplement our Consolidated Financial Statements presented in accordance with GAAP, we use certain non-GAAP financial measures, such as operating net income available to common stockholders, operating earnings per diluted common share, return on average tangible common equity, operating return on average tangible common equity, return on average tangible assets, tangible book value per common share, the ratio of tangible equity to tangible assets, the ratio of tangible common equity to tangible assets, efficiency ratio and net interest margin (FTE) to provide information useful to investors in understanding our

53

operating performance and trends, and to facilitate comparisons with the performance of our peers. Management uses these measures internally to assess and better understand our underlying business performance and trends related to core business activities. The non-GAAP financial measures and key performance indicators we use may differ from the non-GAAP financial measures and key performance indicators other financial institutions use to assess their performance and trends.

These non-GAAP financial measures should be viewed as supplemental in nature, and not as a substitute for, or superior to, our reported results prepared in accordance with GAAP. When non-GAAP financial measures are disclosed, the SEC's Regulation G requires: (i) the presentation of the most directly comparable financial measure calculated and presented in accordance with GAAP and (ii) a reconciliation of the differences between the non-GAAP financial measure presented and the most directly comparable financial measure calculated and presented in accordance with GAAP. Reconciliations of non-GAAP operating measures to the most directly comparable GAAP financial measures are included later in this report under the heading “Reconciliations of Non-GAAP Financial Measures and Key Performance Indicators to GAAP”.

Management believes items such as merger expenses, initial provision for non-PCD loans acquired and branch consolidation costs are not organic to run our operations and facilities. These items are considered significant items impacting earnings as they are deemed to be outside of ordinary banking activities. The merger expenses and branch consolidation costs principally represent expenses to satisfy contractual obligations of the acquired entity or closed branch without any useful ongoing benefit to us. These costs are specific to each individual transaction and may vary significantly based on the size and complexity of the transaction.

To facilitate peer comparisons of net interest margin and efficiency ratio, we use net interest income on a taxable-equivalent basis in calculating net interest margin by increasing the interest income earned on tax-exempt assets (loans and investments) to make it fully equivalent to interest income earned on taxable investments (this adjustment is not permitted under GAAP).  Taxable-equivalent amounts for the 2023 and 2022 periods were calculated using a federal statutory income tax rate of 21%.

FINANCIAL SUMMARY

Net income available to common stockholders for the first quarter of 2023 was $144.5 million or $0.40 per diluted common share, compared to net income available to common stockholders for the first quarter of 2022 of $51.0 million or $0.15 per diluted common share. On an operating basis, earnings per diluted common share (non-GAAP) was $0.40 for the first quarter of 2023, excluding $2.1 million (pre-tax) in merger-related significant items, while the first quarter of 2022 was $0.26, excluding $47.8 million (pre-tax) in merger-related significant items and $4.2 million (pre-tax) in branch consolidation costs.

During the first quarter, we reported record total revenue of $416.0 million, a $103.6 million, or 33% increase from the prior-year quarter, with strong momentum on several key performance metrics including return on average tangible common equity (non-GAAP) of 20%, return on average assets of 1.4%, and an efficiency ratio (non-GAAP) of 50.6%. Our strong financial performance was due to the consistent execution of our conservative business model and focus on customer primacy which led to stable deposit balances, solid capital with a CET1 ratio of 10% and ample liquidity to cover our uninsured and non-collateralized deposits by 170%.

Income Statement Highlights (First quarter of 2023 compared to first quarter of 2022, except as noted)

•Record total revenue of $416.0 million increased $103.6 million, or 33.2%.

•Net interest income increased $102.6 million, or 43.8%, to $336.7 million primarily due to the benefit of growth in earning assets, the impact from the higher interest rate environment, strong deposit growth and prudent management of deposit pricing and betas.

•On a linked-quarter basis net interest income of $336.7 million increased $1.8 million, or 0.5%, from the prior quarter total of $334.9 million, primarily due to growth in average earning assets and net benefits from the higher interest rate environment.

•Net interest margin (FTE) (non-GAAP) increased 95 basis points primarily due to higher yields on loans, investment securities and interest-bearing deposits with banks reflecting the higher interest rate environment, partially offset by increased cost of funds.

•On a linked-quarter basis, the net interest margin (FTE) (non-GAAP) increased 3 basis points to 3.56% as the earning asset yield (non-GAAP) increased 39 basis points and the cost of funds increased 38 basis points.

54

•The annualized net charge-offs to total average loans ratio was 0.18%, compared to 0.03%. While slightly elevated from recent quarters, net charge-offs remain at historically low levels and largely utilized previously established specific reserves.

•The effective tax rate was 19.5%, compared to 20.9%, driven by higher deduction levels from employee stock compensation vesting.

•The efficiency ratio (non-GAAP) was 50.6%, fueled by higher revenue, compared to 60.7% for the year-ago quarter.

Balance Sheet Highlights (period-end balances, March 31, 2023 compared to December 31, 2022, unless otherwise indicated)

•Total average deposits increased $274.2 million, or 0.8%, from the fourth quarter 2022 levels, reflecting organic growth in new and existing customer relationships and inflows from the Union acquisition.

•Period-end deposits remained stable with a slight decrease of $579.7 million, or 1.7%, primarily due to normal seasonal declines in public funds and other corporate deposit balances. From March 8, 2023 to quarter end, total deposit balances decreased slightly by $226 million, or 0.7%, largely due to normal wholesale and retail customer activity. This time frame represents the beginning period of the disruption in the banking industry due to the recent bank failures. We ended the quarter with approximately 76% of deposits insured by the FDIC or collateralized.

•Total average deposits grew $1.2 billion, or 3.7%, from the same prior-year period, led by increases in average time deposits of $1.2 billion, or 42.1%, average non-interest-bearing deposits of $154.6 million, or 1.4%, and average savings deposits of $148.5 million, or 3.8%, more than offsetting the decline in average interest-bearing demand deposits of $323.5 million, or 2.2%. Average deposit growth reflected organic growth in new and existing customer relationships and inflows from the Union acquisition which closed in December 2022 and the Howard acquisition that closed in January 2022.

•Period-end total loans and leases, increased $3.8 billion, or 14.3%, as compared to March 31, 2022, which includes the Union acquired loans. Commercial loans and leases increased $1.9 billion, or 11.0%, and consumer loans increased $1.9 billion, or 20.6%. Our strong organic loan growth was driven by the continued success of our strategy to grow high-quality loans across our diverse geographic footprint.

•On a linked-quarter basis, period-end loans and leases increased $418.3 million, or 1.4%, including an increase of $222.0 million in commercial loans and leases and $196.4 million in consumer loans. Average loans and leases increased $1.0 billion, or 3.6%, linked-quarter, with growth of $795.4 million in commercial loans and leases and $254.3 million in consumer loans.

•The ratio of loans to deposits was 89.7%, compared to 87.0%, as loan growth outpaced deposits. Additionally, the deposit funding mix reflected non-interest-bearing deposits of 33% of total deposits, compared to 34%, reflecting customers' preferences migrating towards savings and time deposits given higher available rates on those products.

•Total assets were $44.1 billion, compared to $43.7 billion, an increase of $421.0 million, or 1.0%, primarily due to organic growth in loans.

•The ratio of the ACL to total loans and leases was stable at 1.32%, compared to 1.33%. The ACL on loans and leases totaled $403 million, compared to $402 million.

•The ratio of non-performing loans and OREO to total loans and OREO decreased 2 basis points to 0.38%. Total delinquency decreased 11 basis points to 0.60%, compared to 0.71%, and continues to remain at a historically low level.

•Tangible book value per common share (non-GAAP) of $8.66, increased $0.39, or 4.7%. AOCI reduced the tangible book value per common share (non-GAAP) by $0.87 as of March 31, 2023, primarily due to the impact of higher interest rates on the fair value of AFS securities, a $0.12 improvement compared to a $0.99 reduction as of December 31, 2022.

•The CET1 regulatory capital ratio was 10.0%, up slightly from 9.8% at December 31, 2022, benefiting from the strong retained earnings growth in the quarter.

55

•During the first quarter of 2023, we repurchased 850,000 shares of common stock at a weighted average share price of $13.78.

Industry Developments

BANKING INDUSTRY DISRUPTION

During the second week of March 2023, Silicon Valley Bank failed and was taken over by federal regulators. The size of the bank, being over $200 billion in assets, made it the second largest U.S. bank to fail. Subsequently that week, Signature Bank with assets over $100 billion, was also closed by federal regulators. On May 1, 2023, it was announced that First Republic Bank was another bank closed by federal regulators. While these failures were idiosyncratic in nature, these events called into question the stability of the entire banking sector and also sparked customer fears of potential loss of deposit balances exceeding the FDIC's $250,000 insurance limit.

While the high-profile bank failures had a diminishing effect on public confidence of the banking system, the federal government took mitigating action. To strengthen public confidence, the federal government announced that that all depositors of both banks would be protected with any losses to the DIF recovered by a special assessment on banks. In addition to those actions, the FRB made available additional funding to eligible depository institutions to help assure banks the ability to meet the needs of all their depositors. This action will bolster the capacity of the banking system to safeguard deposits and ensure the ongoing provision of money and credit to the economy.

The additional funding was made available through the creation of a new BTFP, offering loans of up to one year in length to banks, savings associations, credit unions and other eligible depository institutions pledging U.S. Treasuries, agency debt and mortgage-backed securities and other qualifying assets as collateral. These assets will be valued at par. The BTFP will be an additional source of liquidity against high-quality securities, eliminating an institution's need to quickly sell those securities in

56

times of stress. As of March 31, 2023, we have not participated in this program. Additionally, our total deposit balances have remained stable as a result of our granular deposit base with our average customer deposit account balance at approximately $30,000 (below the peer median) and our median consumer deposit account balance at approximately $5,000 as of quarter-end. FDIC-insured or collateralized deposits represented approximately 76% of our total deposits at March 31, 2023, which was higher than our peer median (based on peer data as of December 31, 2022) and we had ample liquidity to fund up to 170% of our uninsured and non-collateralized deposits.

LIBOR and SOFR

The United Kingdom’s Financial Conduct Authority (FCA), who is the regulator of LIBOR, announced on March 5, 2021 that they will no longer require any panel bank to continue to submit LIBOR after December 31, 2021. As it pertains to U.S. Dollar LIBOR, the FCA announced that certain LIBOR tenors will continue to be published through June 30, 2023. Bank regulators, in a joint statement urged banks to stop using LIBOR altogether on new transactions by the end of 2021 to avoid the possible creation of safety and soundness risk. The FRB of New York has created a working group called the Alternative Reference Rate Committee (ARRC) to assist U.S. institutions in transitioning away from LIBOR as a benchmark interest rate. The ARRC has recommended the use of SOFR as a replacement index for LIBOR.

On March 15, 2022, the Adjustable Interest Rate Act (the LIBOR Act) was signed into law. As required by the LIBOR Act, the FRB's final rule, effective February 27, 2023, identifies FRB-based benchmark replacements for LIBOR contracts that will not mature prior to the LIBOR replacement date and do not contain clear and practical benchmark replacements. The final rule identifies different SOFR-based FRB-selected benchmark replacements for different categories of LIBOR contracts. In addition, the final rule identifies certain benchmark replacement conforming changes related to the implementation, administration and calculation of the FRB-selected benchmark replacement. The final rule expressly indicates that a determining person may select the FRB-selected benchmark which will become the benchmark replacement. Finally, the FRB's final rule preempts any state or local law or standard relating to the selection or use of a benchmark replacement or conforming changes.

We have LIBOR exposure in various agreements, including variable rate loans, derivatives and debt we issued and acquired. We created an internal transition team that is managing our transition away from LIBOR. This transition team is a cross-functional team composed of representatives from the commercial, retail and mortgage banking lines of business, as well as representatives from loan operations, information technology, legal, finance and other support functions. The transition team determined that the primary index to be utilized for loans will be SOFR-based.

Beginning in September 2020, adjustable rate mortgage loans have been originated with SOFR as the underlying index. We started originating commercial loans utilizing SOFR and other indices in the fourth quarter of 2021 and, effective January 1, 2022, ceased origination of LIBOR-based loans. For all existing LIBOR-based loans, remediation efforts are scheduled to be completed by June 30, 2023.

Our transition team continues to work within the guidelines established by the FCA, FRB and the ARRC to provide for a smooth transition away from LIBOR.

RESULTS OF OPERATIONS

Three Months Ended March 31, 2023 Compared to the Three Months Ended March 31, 2022

Net income available to common stockholders for the first three months of 2023 was $144.5 million or $0.40 per diluted common share, compared to $51.0 million or $0.15 per diluted common share for the first three months of 2022. On an operating basis (non-GAAP), net income available to common stockholders for the first three months of 2023 was $146.1 million, or $0.40, compared to $92.0 million or $0.26 per diluted common share for the first three months of 2022. Net interest income totaled $336.7 million, an increase of $102.6 million, or 43.8%, compared to $234.1 million, as total average earning assets increased $2.1 billion, or 5.6%, including a $4.2 billion increase in average loans and leases from organic origination activity and acquired Union loans, as well as a $313.3 million increase in average investment securities. The net interest margin (FTE) (non-GAAP) increased 95 basis points to 3.56%, as the yield on earning assets (non-GAAP) increased 185 basis points to 4.68%, primarily due to higher yields on loans, investment securities and interest-bearing deposits with banks reflecting the higher interest rate environment. The total cost of funds increased 96 basis points to 1.18% with a 136 basis point increase in interest-bearing deposit costs to 1.50%. Between March 31, 2022, and March 31, 2023, the FOMC raised the target Federal Funds interest rate by 450 basis points. The provision for credit losses for the first three months of 2023 totaled $14.1 million, compared to $18.0 million. The year-ago quarter included $19.1 million of initial provision for non-PCD loans associated with the Howard acquisition. Non-interest income totaled $79.4 million, an increase of $1.1 million, or 1.4%, reflecting increased

57

contributions from wealth management and dividends on non-marketable equity securities, partially offset by reduced contributions from mortgage banking due to the sharp increase in interest rates in 2022. Non-interest expense totaled $219.9 million, decreasing $7.5 million, or 3.3%. On an operating basis (non-GAAP), non-interest expense totaled $217.9 million, an increase of $23.2 million, or 11.9%, compared to the first quarter of 2022. Salaries and benefits increased $8.1 million, or 7.2%, due to annual merit increases, reduced salary deferrals given lower loan origination volumes and the addition of the acquired Howard and Union expense bases.

Net Interest Income

Net interest income on an FTE basis (non-GAAP) totaled $339.9 million, increasing $103.3 million, or 43.6%, as the higher interest rate environment benefited earning asset yields given the asset sensitive positioning of the balance sheet, which was partially offset by the higher cost of interest-bearing deposits given customers' preferences migrating toward time deposits and the current competitive interest rate environment. Average earning assets grew $2.1 billion, or 5.6%, primarily driven by organic loan origination activity and acquired Union and Howard loans and an increase in average investment securities. The net interest margin (FTE) (non-GAAP) increased 95 basis points to 3.56%, primarily reflecting higher yields on loans, investment securities and interest-bearing deposits with banks reflecting the higher interest rate environment.

The following table provides certain information regarding changes in net interest income on an FTE basis (non-GAAP) attributable to changes in the average volumes and yields earned on interest-earning assets and the average volume and rates paid for interest-bearing liabilities for the three months ended March 31, 2023, compared to the three months ended March 31, 2022:

(1)The amount of change not solely due to rate or volume changes was allocated between the change due to rate and the change due to volume based on the net size of the rate and volume changes.

(2)Interest income amounts are reflected on an FTE basis (non-GAAP) which adjusts for the tax benefit of income on certain tax-exempt loans and investments using the federal statutory tax rate of 21%. We believe this measure to be the preferred industry measurement of net interest income and provides relevant comparison between taxable and non-taxable amounts.

Interest income on an FTE basis (non-GAAP) of $446.8 million for the first three months of 2023, increased $190.6 million, or 74.4%, from the same period of 2022, resulting from the interest rate increases by the FOMC and a $2.1 billion increase in earning assets. The increase in earning assets was primarily driven by a $4.2 billion, or 15.9%, increase in average loans and an increase in average investment securities of $313.3 million, partially offset by a decrease of $2.3 billion, or 73.7%, in average cash balances. Growth in total average commercial loans included $1.1 billion, or 17.9%, in commercial and industrial loans and $960.9 million, or 9.1%, in commercial real estate driven by a combination of organic loan origination activity led by the Pittsburgh, Cleveland and North Carolina markets, as well as adding the Union loans to portfolio balances. Average consumer loans increased $2.1 billion, or 22.8%, with an increase in residential mortgage loans of $1.4 billion, or 35.0%, reflecting adjustable-rate mortgages held in portfolio on the balance sheet and the continued success of the Physicians First mortgage program, which is a digital program that provides a bundled suite of specialized products to meet the personal and professional needs of physicians, dentists, veterinarians and other healthcare professionals. Additionally, indirect installment loans increased $325.7 million, or 26.8%, and direct home equity installment loans increased $283.3 million, or 11.4%, driven by strong organic loan origination activity throughout 2022. Additionally, the net increase in the securities interest income was a result of replacing maturing securities with higher yielding securities, as the average securities yield increased 59 basis points. For the first three months of 2023, the yield on average earning assets (non-GAAP) increased 185 basis points to 4.68%,

60

compared to the first three months of 2022, primarily due to higher yields on loans, investment securities and interest-bearing deposits with banks reflecting the higher interest rate environment.

Interest expense of $106.8 million for the first three months of 2023 increased $87.3 million, or 447.8%, from the same period of 2022, primarily due to the higher interest rate environment and an increase in average interest-bearing deposits. The growth in average deposits reflected solid organic growth in new and existing customer relationships and inflows from the Union and Howard acquisition. Average interest-bearing deposits increased $1.1 billion, or 4.9%, which reflects the benefit of solid organic growth in customer relationships and the addition of the Union and Howard acquisition. Average time deposits increased $1.2 billion, or 42.1%, as customer preferences shifted towards certificates of deposits as interest rates increased. Average long-term borrowings increased $372.2 million, or 52.4%, primarily due to an increase of $228.5 million in senior debt resulting from the issuance of $350 million in 5.150% fixed-rate senior notes during August 2022, partially offset by the maturity of $300 million in 2.20% fixed-rate senior notes in February 2023. Additionally, long-term FHLB borrowings increased $101.1 million. The rate paid on interest-bearing liabilities increased 137 basis points to 1.70% for the first three months of 2023, compared to the first three months of 2022, as the cost of interest-bearing deposits increased 136 basis points from 0.14% to 1.50%. These increases were primarily a result of the interest rate actions taken by the FOMC, combined with the issuance of senior debt in August 2022.

Provision for Credit Losses

The following table presents information regarding the provision for credit loss expense and net charge-offs:

The provision for credit losses was $14.1 million, compared to $18.0 million in the first quarter of 2022. The provision for credit losses in the first quarter of 2022 included $19.1 million of initial provision for non-PCD loans associated with the Howard acquisition. The provision for credit losses for the first quarter of 2023 was primarily due to loan growth, CECL-related model impacts from forecasted macroeconomic conditions, and charge-off activity. The first quarter of 2023 reflected net charge-offs of $13.2 million, or 0.18% annualized of total average loans, compared to $1.9 million, or 0.03% annualized, in the first quarter of 2022. While slightly elevated from the year-ago quarter, net charge-offs remain at historically low levels. The ACL was $403.4 million, an increase of $32.8 million, with the ratio of the ACL to total loans and leases decreasing 7 basis points to 1.32%, reflecting the strong loan growth, partially offset by the increase in the ACL.

Total non-interest income	$	79,389	$	78,322	$	1,067	1.4	%

Total non-interest income increased $1.1 million, or 1.4%. The variances in significant individual non-interest income items are explained in the following paragraphs.

Service charges of $32.6 million increased $1.1 million, or 3.6%, driven by treasury management services and interchange fees, offsetting the expected decline in overdraft and non-sufficient fund service charges from the previously announced overdraft practice changes that we implemented in the first quarter of 2023.

Securities commissions and fees of $7.4 million increased $1.7 million, or 29.7%, due to record securities commissions and fees driven by higher transaction activity and annuity sales.

Mortgage banking operations income of $4.9 million decreased $1.8 million, or 27.2%, as secondary market revenue and mortgage held-for-sale pipelines declined from 2022 levels given the sharp increase in mortgage rates and growth in adjustable-rate mortgage originations which we held in portfolio on the balance sheet. During the first three months of 2023, we sold $206.7 million of residential mortgage loans, a 45.7% decrease compared to $380.7 million for the same period of 2022.

Dividends on non-marketable equity securities of $4.1 million increased $2.0 million, or 91.1%, reflecting increases in both FRB and FHLB dividends given the higher interest-rate environment.

Other non-interest income was $2.4 million and $4.6 million for the first three months of 2023 and 2022, respectively, as SBA premium income declined $1.1 million from elevated 2022 levels as the higher interest rate environment reduced market premiums and correspondingly lowered sold loan volumes. Additionally, Small Business Investment Company (SBIC) funds income was $0.9 million lower.

Non-Interest Expense

The breakdown of non-interest expense for the three months ended March 31, 2023 and 2022 is presented in the following table:

TABLE 8

	Three Months Ended March 31,				$		%

Total non-interest expense	$	219,917	$	227,426	$	(7,509)	(3.3)	%

Total non-interest expense of $219.9 million for the first three months of 2023 decreased $7.5 million, a 3.3% decrease from the same period of 2022. On an operating basis, non-interest expense (non-GAAP) increased $23.2 million, or 11.9%, when excluding significant items of $2.1 million in merger-related costs in the first three months of 2023, compared to $28.6 million in merger-related costs and $4.2 million in branch consolidation costs in the first three months of 2022. The variances in the individual non-interest expense items are further explained in the following paragraphs.

Salaries and employee benefits of $120.2 million increased $8.1 million, or 7.2%, due to annual merit increases, reduced salary deferrals given lower loan origination volumes and the addition of the acquired Howard and Union expense bases. Included in salaries and employee benefits in the first quarter of 2023 and 2022 were $6.7 million and $6.2 million, respectively, related to normal seasonal long-term compensation expense.

Net occupancy and equipment expense of $39.4 million increased $3.2 million, or 9.0%, primarily from the acquired Howard and Union expense bases, as well as technology-related investments.

Amortization of intangibles of $5.1 million increased $1.9 million, or 58.6%, primarily related to the Union core deposit intangible.

Outside services increased $2.4 million, or 13.9%, with higher volume-related technology and third-party costs, as well as the acquired Howard and Union expense bases.

FDIC insurance of $7.1 million increased $2.5 million, or 55.6%, primarily due to the previously announced FDIC assessment rate increase which was effective in the first quarter of 2023.

We recorded $2.1 million in merger-related costs related to the Union acquisition completed in December 2022, compared to $28.6 million in the first three months of 2022 related to the Howard acquisition completed in January 2022.

Income Taxes

The following table presents information regarding income tax expense and certain tax rates:

Income tax expense	$	35,560		$	14,015
Effective tax rate	19.5		%	20.9		%
Statutory federal tax rate	21.0			21.0

Income tax expense was higher in 2023 due to higher pre-tax earnings, as we had merger-related expense from the Howard acquisition in 2022. However, the effective tax rate was lower in 2023 as a result of higher deduction levels from employee stock compensation vesting.

Lending Activity

The loan and lease portfolio consists principally of loans and leases to individuals and small- and medium-sized businesses within our primary markets 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.

Following is a summary of loans and leases:

TABLE 12

Total loans and leases	$	30,673	$	30,255	$	418	1.4	%

65

The commercial and industrial growth was led by activity in the Pittsburgh, Cleveland and North Carolina markets while the growth in residential mortgages reflected growth in adjustable-rate mortgages held in portfolio on the balance sheet and the continued success of our Physicians First mortgage program. Our commercial real estate portfolio was comprised of $8 billion of non-owner occupied loans of which 22% represented office space. Office space was primarily made up of smaller offices located outside of metropolitan business districts.

Non-Performing Assets

Following is a summary of non-performing assets:

TABLE 13

Non-performing assets decreased $0.8 million, from $119.5 million at December 31, 2022 to $118.7 million at March 31, 2023. This reflects a decrease of $0.1 million in non-performing loans and leases and a decrease of $0.7 million in OREO.

Allowance for Credit Losses on Loans and Leases

The model used to calculate the ACL is dependent on the portfolio composition and credit quality, as well as historical experience, current conditions and forecasts of economic conditions and interest rates. Specifically, the following considerations are incorporated into the ACL calculation:

•a third-party macroeconomic forecast scenario;

•a 24-month R&S forecast period for macroeconomic factors with a reversion to the historical mean on a straight-line basis over a 12-month period; and

•the historical through-the-cycle default mean calculated using an expanded period to include a prior recessionary period.

At March 31, 2023 and December 31, 2022, we utilized a third-party consensus macroeconomic forecast reflecting the current and projected macroeconomic environment. For our ACL calculation at March 31, 2023, the macroeconomic variables that we utilized included, but were not limited to: (i) the purchase only Housing Price Index, which declines 2.5% over our R&S forecast period, (ii) a Commercial Real Estate Price Index, which declines 4.6% over our R&S forecast period, (iii) S&P Volatility, which decreases 39.7% in 2023 and 10.5% in 2024 and (iv) bankruptcies, which increase steadily over the R&S forecast period but average below historic levels. Macroeconomic variables that we utilized for our ACL calculation as of December 31, 2022 included, but were not limited to: (i) the purchase only Housing Price Index, which declines 3.7% over our R&S forecast period, (ii) a Commercial Real Estate Price Index, which declines 0.9% over our R&S forecast period, (iii) S&P Volatility, which decreases 41.0% in 2023 and 8.1% in 2024 and (iv) bankruptcies, which increase steadily over the R&S forecast period but average below historical levels.

Allowance for credit losses/total loans and leases					1.32	%	1.38	%
Allowance for credit losses/non-performing loans					356.09	%	364.99	%

The ACL on loans and leases of $403.4 million at March 31, 2023 increased $1.7 million, or 0.4%, from December 31, 2022. Our ending ACL coverage ratio at March 31, 2023 was stable at 1.32%, compared to 1.33% at December 31, 2022. Total provision for credit losses for the three months ended March 31, 2023 was $14.1 million, compared to $18.0 million for the same period in 2022 with the year-ago quarter reflecting $19.1 million of initial provision for non-PCD loans associated with the Howard acquisition. Net charge-offs were $13.2 million for the three months ended March 31, 2023, compared to $1.9 million for the first three months of 2022. While slightly elevated from the year-ago quarter, net charge-offs remain at historically low levels. The ACL as a percentage of non-performing loans for the total portfolio was flat at 356% as of March 31, 2023 compared to 354% as of December 31, 2022.

Deposits

Our primary source of funds is deposits. Our diversified and granular deposit base are provided by business, consumer and municipal customers who we serve within our footprint.

Following is a summary of deposits:

TABLE 15

(in millions)	March 31, 2023		December 31, 2022		$ Change		% Change
Non-interest-bearing demand	$	11,297	$	11,916	$	(619)	(5.2)	%
Interest-bearing demand	14,091		15,100		(1,009)		(6.7)
Savings	4,053		4,142		(89)		(2.1)
Certificates and other time deposits	4,749		3,612		1,137		31.5
Total deposits	$	34,190	$	34,770	$	(580)	(1.7)	%

Total deposits decreased $579.7 million, or 1.7%, from December 31, 2022, primarily due to normal seasonal declines in public funds deposit balances. Even with the banking industry disruption in early March, our deposit balances remained stable as total deposit balances decreased slightly by $226 million, or 0.7%, from March 8, 2023 to quarter end, largely due to normal business and consumer activity of our customers. We ended the quarter with approximately 76% of all deposits insured by the FDIC or collateralized. Additionally, customer preferences shifted to certificates of deposits as interest rates increased.

Capital Resources and Regulatory Matters

The access to, and cost of, funding for new business initiatives, the ability to engage in expanded business activities, the ability to pay dividends and the level and nature of regulatory oversight depend, in part, on our capital position.

The assessment of capital adequacy depends on a number of factors such as expected organic growth in the Consolidated Balance Sheet, asset quality, liquidity, earnings performance and sustainability, changing competitive conditions, regulatory changes or actions, and economic forces. We seek to maintain a strong capital base to support our growth and expansion activities, to provide stability to current operations and to promote public confidence.

We have an effective shelf registration statement filed with the SEC. Pursuant to this registration statement, we may, from time to time, issue and sell in one or more offerings any combination of common stock, preferred stock, debt securities, depositary shares, warrants, stock purchase contracts or units. On August 25, 2022, we completed an offering of $350 million of 5.150% fixed-rate senior notes due in 2025 under this registration statement. The net proceeds of the debt offering after deducting underwriting discounts and commissions and offering expenses were $347.4 million. We used the net proceeds from the sale of the notes for general corporate purposes, including repayment of the $300 million in 2.200% senior notes that matured in February 2023, investments at the holding company level, capital to support the growth of FNBPA and refinancing of outstanding indebtedness.

On April 18, 2022, we announced that our Board of Directors approved an additional $150 million for the repurchase of our common stock through our existing share repurchase program bringing the total authorization to $300 million. Since inception, we repurchased 11.8 million shares at a weighted average share price of $11.50 for $136.1 million under this repurchase program, with $163.9 million remaining for repurchase. The repurchases will be made from time to time on the open market at prevailing market prices or in privately negotiated transactions. The purchases will be funded from available working capital. There is no guarantee as to the exact number of shares that will be repurchased and we may discontinue purchases at any time. The Inflation Reduction Act of 2022 includes a 1% excise tax on stock repurchases beginning January 1, 2023.

Capital management is a continuous process, with capital plans and stress testing for FNB and FNBPA updated at least annually. These capital plans include assessing the adequacy of expected capital levels assuming various scenarios by projecting capital needs for a forecast period of 2-3 years beyond the current year. From time to time, we issue shares initially acquired by us as treasury stock under our various benefit plans. We may issue additional preferred or common stock to maintain our well-capitalized status.

FNB and FNBPA are subject to various regulatory capital requirements administered by the federal banking agencies (see discussion under “Enhanced Regulatory Capital Standards”). Quantitative measures established by regulators to ensure capital adequacy require FNB and FNBPA to maintain minimum amounts and ratios of total, tier 1 and CET1 capital (as defined in the regulations) to risk-weighted assets (as defined) and of leverage ratio (as defined). Failure to meet minimum capital requirements could lead to initiation of certain mandatory, and possibly additional discretionary actions, by regulators that, if undertaken, could have a direct material effect on our Consolidated Financial Statements, dividends and future business and corporate strategies. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, FNB and FNBPA must meet specific capital guidelines that involve quantitative measures of assets, liabilities and certain off-balance sheet items as calculated under regulatory accounting practices. FNB’s and FNBPA’s capital amounts and classifications are also subject to qualitative judgments by the regulators about components, risk weightings and other factors.

At March 31, 2023, the capital levels of both FNB and FNBPA exceeded all regulatory capital requirements and their regulatory capital ratios were above the minimum levels required to be considered “well-capitalized” for regulatory purposes.

In December 2018, the FRB and other U.S. banking agencies approved a rule to address the impact of CECL on regulatory capital by allowing bank holding companies (BHCs) and banks, including FNB, the option to phase in the day-one impact of CECL over a three-year period. In March 2020, the FRB and other U.S. banking agencies issued a final rule that became effective on March 31, 2020, and provides BHCs and banks with an alternative option to temporarily delay the impact of CECL, relative to the incurred loss methodology for the ACL, on regulatory capital. We have elected this alternative option instead of the one described in the December 2018 rule. As a result, under the final rule, we delayed recognizing the estimated impact of CECL on regulatory capital until after a two-year deferral period, which for us extended through December 31, 2021. Beginning on January 1, 2022, we were required to phase in 25% of the previously deferred capital impact of CECL, with an additional 25% to be phased in at the beginning of each subsequent year until fully phased in by the first quarter of 2025. Under the final rule, the estimated impact of CECL on regulatory capital that we will defer and later phase in is calculated as the entire day-one impact at adoption plus 25% of the subsequent change in the ACL during the two-year deferral period. As of

68

March 31, 2023, the total deferred impact on CET1 capital related to our adoption of CECL was approximately $34.4 million, or 10 basis points, which will continue to be reduced by approximately $17.2 million annually.

In this unprecedented economic and uncertain environment, we frequently run stress tests for a variety of economic situations, including severely adverse scenarios that have economic conditions like the current conditions. Under these scenarios, the results of these stress tests indicate that our regulatory capital ratios would remain above the regulatory requirements and we would be able to maintain appropriate liquidity levels, demonstrating our expected ability to continue to support our constituencies under stressful financial conditions.

Following are the capital amounts and related ratios for FNB and FNBPA:

Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 (Dodd-Frank Act)

The Dodd-Frank Act broadly affects the financial services industry by establishing a framework for systemic risk oversight, creating a resolution authority for institutions determined to be systemically important, mandating higher capital and liquidity requirements, requiring banks to pay increased fees to regulatory agencies and containing numerous other provisions aimed at strengthening the sound operation of the financial services sector that significantly change the system of regulatory oversight as described in more detail under Part I, Item 1, “Business - Government Supervision and Regulation” included in our 2022 Annual Report on Form 10-K as filed with the SEC on February 24, 2023.

LIQUIDITY

Our primary liquidity management goal is to satisfy the cash flow requirements of customers and the operating cash needs of FNB with cost-effective funding. Our Board of Directors has established an Asset/Liability Management Policy to guide management in achieving and maintaining earnings performance consistent with long-term goals, while maintaining acceptable levels of interest rate risk, a “well-capitalized” Balance Sheet and adequate levels of liquidity. Our Board of Directors has also established Liquidity and Contingency Funding Policies to guide management in addressing the ability to identify, measure, monitor and control both normal and stressed liquidity conditions. These policies designate our ALCO as the body responsible for meeting these objectives. The ALCO, which is comprised of members of executive management, reviews liquidity on a continuous basis and approves significant changes in strategies that affect Balance Sheet or cash flow positions. Liquidity is centrally managed daily by our Treasury Department. Liquidity sources from assets include payments from loans and investments, as well as the ability to securitize, pledge or sell loans, investment securities and other assets. Liquidity sources from liabilities are generated primarily through the banking offices of FNBPA in the form of deposits and customer repurchase agreements. FNB also has access to reliable and cost-effective wholesale sources of liquidity. Short- and long-term funds are available for use to help fund normal business operations, and unused credit availability can be utilized to serve as contingency funding if faced with a liquidity crisis.

The principal sources of the parent company’s liquidity are its strong existing cash resources plus dividends and interest it receives from its subsidiaries. These dividends may be impacted by the parent’s or its subsidiaries’ capital needs, statutory laws and regulations, corporate policies, contractual restrictions, profitability and other factors. In addition, through one of our subsidiaries, we regularly issue subordinated notes, which are guaranteed by FNB. The cash position at March 31, 2023 was $360.3 million, down $294.0 million from year-end, primarily due to the repayment of $300 million in Senior Notes due in February 2023. During the third quarter of 2022, we completed a Senior Debt offering of which $347.7 million net proceeds were used to retire debt in February of 2023 (for additional information, see Note 10, "Borrowings" in the Notes to the Consolidated Financial Statements in this Report). Management has utilized various strategies to ensure sufficient cash on hand is available to meet the parent's funding needs.

Two metrics that are used to gauge the adequacy of the parent company’s cash position are the Liquidity Coverage Ratio (LCR) and Months of Cash on Hand (MCH). The LCR is defined as the sum of cash on hand plus projected cash inflows over the next 12 months divided by projected cash outflows over the next 12 months. The MCH is defined as the number of months of corporate expenses and dividends that can be covered by the cash on hand.

The LCR and MCH ratios are presented in the following table:

TABLE 17

	March 31, 2023	December 31, 2022	Internal Limit
Liquidity coverage ratio	2.5 times	1.7 times	> 1 time
Months of cash on hand	15.4 months	13.6 months	> 12 months

Management has concluded that our cash levels remain appropriate given the current market environment.

Over time, our liquidity position has been positively impacted by our ability to generate growth in relationship-based accounts. Organic growth in low-cost transaction deposits was complemented by management’s continued strategy of deposit gathering efforts focused on attracting new customer relationships and deepening relationships with existing customers, in part through internal lead generation efforts leveraging data analytics capabilities.  Total deposits decreased $579.7 million, or 1.7%, from December 31, 2022, primarily due to normal seasonal declines in public funds and other corporate deposit balances. From March 8, 2023 to quarter-end, total deposit balances decreased slightly by $226 million, or 0.7%, largely due to normal wholesale and retail customer activity. We ended the quarter with approximately 76% of deposits insured by the FDIC or

70

collateralized, an improvement from approximately 74% at December 31, 2022. Non-interest-bearing demand deposit accounts decreased $618.9 million, or 5.2%. Interest-bearing demand deposits decreased $1.0 billion, or 6.7% and savings account balances decreased $89.3 million, or 2.2%, while time deposits increased $1.1 billion, or 31.5%, as customers' preferences are shifting back to certificates of deposits (CDs) as interest rates have increased substantially. In an abundance of caution related to the banking industry disruption, between March 8th and March 31st, we executed approximately $1.3 billion in wholesale borrowings including advances from the FHLB and overnight borrowings in the Fed Funds market, which added cash on the balance sheet, supported loan growth and covered the deposit decline. Additionally, our cash balances held at the FRB increased $147.7 million from December 31, 2022 to $1.3 billion at March 31, 2023.

We continue to have ample unused borrowing capacity that could cover 1.7 times of the uninsured deposit and non-collateralized deposit balances as of March 31, 2023. A portion of this capacity includes the FRB's Discount Window and their newly created BTFP. We had no borrowings under either facility during the quarter. Additional sources of unused wholesale credit availability for FNBPA include the ability to borrow from the FHLB, correspondent bank lines, and access to other channels. In addition to credit availability, FNBPA also possesses salable unpledged government and agency securities that could be utilized to meet funding needs. We currently have excess cash to meet our pledging requirements. At March 31, 2023, we have $2.3 billion of cash and salable unpledged government and agency securities to total assets, or 5.2%. This compares to a policy minimum of 3.0%.

The following table presents certain information relating to FNBPA’s credit availability and salable unpledged securities:

TABLE 18

(dollars in millions)	March 31, 2023			December 31, 2022
Unused wholesale credit availability	$	16,070		$	15,669

Salable unpledged government and agency securities as a % of FNBPA assets	2.3		%	1.4		%
Cash and salable unpledged government and agency securities as a % of FNBPA assets	5.2		%	3.9		%

Another metric for measuring liquidity risk is the liquidity gap analysis. The following liquidity gap analysis as of March 31, 2023 compares the difference between our cash flows from existing earning assets and interest-bearing liabilities over future time intervals. Management monitors the size of the liquidity gaps so that sources and uses of funds are reasonably matched in the normal course of business and in relation to implied forward rate expectations. A reasonably matched position lays a better foundation for dealing with additional funding needs during a potential liquidity crisis. A positive gap position means that more assets are expected to mature over the next 12 months than liabilities. The twelve-month cumulative gap to total assets ratio was 1.6% as of March 31, 2023, compared to 3.8% as of December 31, 2022. The change in the twelve-month cumulative gap to total assets was primarily related to the active management of deposit pricing across the deposit product maturity tenors which reduced our asset sensitivity. Management calculates this ratio at least quarterly and it is reviewed regularly by ALCO.

In addition, the ALCO regularly monitors various liquidity ratios, stress scenarios of our liquidity position and assumptions considering market disruptions, lending demand, deposit behavior, and funding availability. The stress scenarios forecast that adequate funding will be available even under severe conditions. Management believes we have sufficient liquidity available to meet our normal operating and contingency funding cash needs.

MARKET RISK

Market risk refers to potential losses arising predominately from changes in interest rates, foreign exchange rates, equity prices and commodity prices. We are primarily exposed to interest rate risk inherent in our lending and deposit-taking activities as a financial intermediary. To succeed in this capacity, we offer an extensive variety of financial products to meet the diverse needs of our customers. These products sometimes contribute to interest rate risk for us when product groups do not complement one another. For example, depositors may want short-term deposits, while borrowers may desire long-term loans.

Changes in market interest rates may result in changes in the fair value of our financial instruments, cash flows and net interest income. Subject to its ongoing oversight, the Board of Directors has given ALCO the responsibility for market risk management, which involves devising policy guidelines, risk measures and limits, and managing the amount of interest rate risk and its effect on net interest income and capital. We use derivative financial instruments for interest rate risk management purposes and not for trading or speculative purposes.

Interest rate risk is comprised of repricing risk, basis risk, yield curve risk and options risk. Repricing risk arises from differences in the cash flow or repricing between asset and liability portfolios. Basis risk arises when asset and liability portfolios are related to different market rate indices, which do not always change by the same amount. Yield curve risk arises when asset and liability portfolios are related to different maturities on a given yield curve; when the yield curve changes shape, the risk position is altered. Options risk arises from “embedded options” within asset and liability products as certain borrowers have the option to prepay their loans, which may be with or without penalty, when rates change, while certain depositors can redeem their certificates of deposit early, which may be with or without penalty, when rates change.

We use an asset/liability model to measure our interest rate risk. Interest rate risk measures we utilize include earnings simulation, EVE and gap analysis. Gap analysis and EVE are static measures that do not incorporate assumptions regarding future business. Gap analysis, while a helpful diagnostic tool, displays cash flows for only a single rate environment. EVE’s long-term horizon helps identify changes in optionality and longer-term positions. However, EVE’s liquidation perspective does not translate into the earnings-based measures that are the focus of managing and valuing a going concern. Net interest income simulations explicitly measure the exposure to earnings from changes in market rates of interest. In these simulations, our current financial position is combined with assumptions regarding future business to calculate net interest income under various hypothetical rate scenarios. The ALCO regularly reviews earnings simulations over multiple years under various interest rate scenarios. Reviewing these various measures provides us with a comprehensive view of our interest rate risk profile, which provides the basis for balance sheet management strategies.

72

The following repricing gap analysis as of March 31, 2023 compares the difference between the amount of interest-earning assets and interest-bearing liabilities subject to repricing over a period of time. Management utilizes the repricing gap analysis as a diagnostic tool in managing net interest income and EVE risk measures.

Cumulative Gap to Assets	0.8		%	1.4		%	2.7		%	4.0		%

The twelve-month cumulative repricing gap to total assets was 4.0% and 8.4% as of March 31, 2023 and December 31, 2022, respectively. The positive cumulative gap positions indicate that we have a greater amount of repricing earning assets than repricing interest-bearing liabilities over the subsequent twelve months. The change in the cumulative repricing gap at March 31, 2023, compared to December 31, 2022, is primarily related to customers moving into higher yielding deposit products and shorter-term time deposits.

The allocation of non-maturity deposits and customer repurchase agreements to the one-month maturity category above is based on the estimated sensitivity of each product to changes in market rates. For example, if a product’s rate is estimated to increase by 50% as much as the market rates, then 50% of the account balance was placed in this category.

Using a static Balance Sheet structure and utilizing net interest income simulations, the following net interest income metrics were calculated using rate shocks which move market rates in an immediate and parallel fashion. The variance percentages represent the change between the net interest income and EVE calculated under the particular rate scenario compared to the net interest income and EVE that was calculated assuming market rates as of March 31, 2023. The measures do not reflect management's potential actions.

73

The following table presents an analysis of the potential sensitivity of our net interest income and EVE to changes in interest rates using rate shocks:

TABLE 21

	March 31, 2023		December 31, 2022		ALCO Limits
Net interest income change (12 months):
+ 300 basis points	4.1	%	5.5	%	n/a
+ 200 basis points	2.8		3.3		(5.0)	%
+ 100 basis points	1.4		1.1		(5.0)
- 100 basis points	2.9		1.2		(5.0)
- 200 basis points	3.6		0.9		(5.0)
Economic value of equity:
+ 300 basis points	1.7		(6.8)		(25.0)
+ 200 basis points	2.6		(4.0)		(15.0)
+ 100 basis points	1.7		(1.4)		(10.0)
- 100 basis points	(3.5)		(2.0)		(10.0)
- 200 basis points	(8.3)		(5.8)		(15.0)

We also model rate scenarios which move all rates gradually over twelve months (Rate Ramps) and model scenarios that gradually change the shape of the yield curve. The comparative percentages are based on the projected base net interest income at the respective measurement dates. Assuming a static Balance Sheet, a +100 basis point Rate Ramp increases net interest income (12 months) by 1.0% at March 31, 2023 and 0.5% at December 31, 2022. For a +200 basis point Rate Ramp, net interest income (12 months) increases by 1.9% at March 31, 2023 and 2.0% at December 31, 2022. The corresponding metrics for a minus 100 basis point Rate Ramp are 1.6% and 0.6% at March 31, 2023 and December 31, 2022, respectively. These results use historical long-term deposit rate beta assumptions for both rising and falling rate scenarios. Recent market events and the relatively fast rise in short-term Treasury rates suggest the possibility of lower deposit rate betas in falling rate scenarios in an effort to retain deposit balances in the flat balance simulation. Sensitivity analysis using lower betas in the minus 100 basis point Rate Shock decreases net interest income (12 months) by (0.9%) at March 31, 2023. The corresponding metric for a minus 100 basis point Rate Ramp is (0.4%) at March 31, 2023. These changes are a direct result of our managing our interest rate exposure to benefit from higher rates during 2022. Management has reduced our exposure to higher interest rates as prospects for additional FOMC interest rate hikes has moderated and we will continue to manage to a more neutral position.

Forty-eight percent of our net loans and leases are indexed to short-term LIBOR, SOFR, Prime and other indices that reprice within the next three months. Our cash position related to increased deposits has also been a significant factor in our asset sensitivity metrics. The deployment of cash into loans and investments, as well as a higher base net interest income due to the increase in the loan indices, are the primary factors of the change in the percentage sensitivity since December. The FOMC increased the Federal Funds rate by 425 basis points in 2022 and by 50 basis points in the first quarter of 2023. Our balance sheet is positioned to benefit, in the near term, from further FOMC increases of the Federal Funds rate.

There are multiple factors that influence our interest rate risk position and impact net interest income. These include external factors such as the shape of the yield curve and expectations regarding future interest rates, as well as internal factors regarding product offerings, product mix and pricing of loans and deposits.

Management continues to be proactive in managing our interest rate risk (IRR) position. In particular, we have made use of interest rate swaps to commercial borrowers (commercial swaps) to manage our IRR position as the commercial swaps effectively increase our level of adjustable-rate loans. Total variable and adjustable-rate loans were 60.4% of total net loans and leases as of March 31, 2023 and 60.2% as of December 31, 2022. As of March 31, 2023, the commercial swaps totaled $5.4 billion of notional principal, with $213 million in original notional swap principal originated during the first three months of 2023. Furthermore, we regularly sell long-term fixed-rate residential mortgages in the secondary market and have been successful in the origination of consumer and commercial loans with short-term repricing characteristics. Further, during 2023, management has adjusted our IRR position by opportunistically deploying excess cash balances into higher yielding loans and actively managed customer preferences for higher yielding deposit products and, in particular, shorter term time deposits. We also have outstanding derivatives to manage the IRR position. For additional information regarding interest rate swaps, see Note 11, "Derivative Instruments and Hedging Activities" in the Notes to the Consolidated Financial Statements in this Report.

74

We recognize that all asset/liability models have some inherent shortcomings. Asset/liability models require certain assumptions to be made, such as prepayment rates on interest-earning assets and repricing impact on non-maturity deposits, which may differ from actual experience. These business assumptions are based upon our experience, business plans, economic and market trends and available industry data. While management believes that its methodology for developing such assumptions is reasonable, there can be no assurance that modeled results will be achieved. Furthermore, the metrics are based upon the Balance Sheet structure as of the valuation date and do not reflect the planned growth or management actions that could be taken.

RISK MANAGEMENT

As a financial institution, we take on a certain amount of risk in every business decision, transaction and activity. Our Board of Directors and senior management have identified seven major categories of risk: credit risk, market risk, liquidity risk, reputational risk, operational risk, legal and compliance risk and strategic risk. In its oversight role of our risk management function, the Board of Directors focuses on the strategies, analyses and conclusions of management relating to identifying, understanding and managing risks to optimize total shareholder value, while balancing prudent business and safety and soundness considerations.

The Board of Directors adopted a risk appetite statement that defines acceptable risk levels and limits under which we seek to operate in order to optimize returns. As such, the board monitors a series of KRIs, or Key Risk Indicators, for various business lines, operational units, and risk categories, providing insight into how our performance aligns with our stated risk appetite. These results are reviewed periodically by the Board of Directors and senior management to ensure adherence to our risk appetite statement, and where appropriate, adjustments are made to applicable business strategies and tactics where risks are approaching stated tolerances or for emerging risks.

We support our risk management process through a governance structure involving our Board of Directors and senior management. The joint Risk Committee of our Board of Directors and the FNBPA Board of Directors helps ensure that business decisions are executed within appropriate risk tolerances. The Risk Committee has oversight responsibilities with respect to the following:

•identification, measurement, assessment and monitoring of enterprise-wide risk;

•development of appropriate and meaningful risk metrics to use in connection with the oversight of our businesses and strategies;

•review and assessment of our policies and practices to manage our credit, market, liquidity, legal, regulatory and operating risk (including technology, operational, compliance and fiduciary risks); and

•identification and implementation of risk management best practices.

The Risk Committee serves as the primary point of contact between our Board of Directors and the Risk Management Council, which is the senior management level committee responsible for risk management. Risk appetite is an integral element of our business and capital planning processes through our Board Risk Committee and Risk Management Council. We use our risk appetite processes to promote appropriate alignment of risk, capital and performance tactics, while also considering risk capacity and appetite constraints from both financial and non-financial risks. Our top-down risk appetite process serves as a limit for undue risk-taking for bottom-up planning from our various business functions. Our Board Risk Committee, in collaboration with our Risk Management Council, approves our risk appetite on an annual basis, or more frequently, as needed to reflect changes in the risk, regulatory, economic and strategic plan environments, with the goal of ensuring that our risk appetite remains consistent with our strategic plans and business operations, regulatory environment and our shareholders' expectations. Reports relating to our risk appetite and strategic plans, and our ongoing monitoring thereof, are regularly presented to our various management level risk oversight and planning committees and periodically reported up through our Board Risk Committee.

As noted above, we have a Risk Management Council comprised of senior management. The purpose of this committee is to provide regular oversight of specific areas of risk with respect to the level of risk and risk management structure. Management has also established an Operational Risk Committee that is responsible for identifying, evaluating and monitoring operational risks across FNB, evaluating and approving appropriate remediation efforts to address identified operational risks and providing periodic reports concerning operational risks to the Risk Management Council. The Risk Management Council reports on a regular basis to the Risk Committee of our Board of Directors regarding our enterprise-wide risk profile and other significant risk management issues. Our Chief Risk Officer is responsible for the design and implementation of our enterprise-wide risk

75

management strategy and framework through the multiple second line of defense areas, including the following departments, which all report to the Chief Risk Officer to ensure the coordinated and consistent implementation of risk management initiatives and strategies on a day-to-day basis:

•Enterprise-Wide Risk Management Department - conducts risk and control assessments across all our business and operational areas to ensure the appropriate risk identification, risk management and reporting of risks enterprise wide.

•Fraud Risk Department - monitors for internal and external fraud risk across all our business and operational units.

•Loan Review Department - conducts independent testing of our loan risk ratings to ensure their accuracy, which is instrumental to calculating our ACL.

•Model Risk Management Department - oversees validation and testing of all models used in managing risk across our company.

•Third-Party Risk Management Department - ensures effective risk management and oversight of third-party relationships throughout the vendor life cycle.

•Anti-Money Laundering and Bank Secrecy Act Department - monitors for compliance with money laundering risk and associated regulatory compliance requirements.

•Appraisal Review Department - facilitates independent ordering and review of real estate appraisals obtained for determining the value of real estate pledged as collateral for loans to customers.

•Compliance Department - develops policies and procedures and monitors compliance with applicable laws and regulations which govern our business operations.

•Information and Cyber Security Department - maintains a risk assessment of our information and cybersecurity risks and ensures appropriate controls are in place to manage and control such risks, using the National Institute of Standards and Technology framework for improving critical infrastructure by measuring and evaluating the effectiveness of information and cybersecurity controls. This department also oversees our disaster recovery planning and testing efforts to allow us to be capable and ready for business resumption in the event of a disaster.

We have in place various business and emergency continuity plans to respond to different crises and circumstances which include rapid deployment of our Crisis Management Team, Incident Management Team and Business Continuity Coordinators to activate our plans for various types of emergency circumstances. Further, our audit function performs an independent assessment of our internal controls environment and plays an integral role in testing the operation of the internal controls systems and reporting findings to management and our Audit Committee. Each of the Risk, Audit, Credit Risk and CRA Committees of our Board of Directors regularly report on risk-related matters to the full Board of Directors. In addition, both the Risk Committee of our Board of Directors and our Risk Management Council regularly assess our enterprise-wide risk profile and provide guidance on actions needed to address key and emerging risk issues.

The Board of Directors believes that our enterprise-wide risk management process is effective and enables the Board of Directors to:

•assess the quality of the information they receive;

•understand the businesses, investments and financial, accounting, legal, regulatory and strategic considerations and the risks that FNB faces;

•oversee and assess how senior management evaluates risk; and

•assess appropriately the quality of our enterprise-wide risk management processes.

The table above shows how operating net income available to common stockholders (non-GAAP) is derived from amounts reported in our financial statements. We believe certain charges, such as merger expenses, initial provision for non-PCD loans acquired and branch consolidation costs are not organic costs to run our operations and facilities. The merger expenses and branch consolidation costs principally represent expenses to satisfy contractual obligations of the acquired entity or closed branches without any useful ongoing benefit to us. These costs are specific to each individual transaction, and may vary significantly based on the size and complexity of the transaction.

ITEM 3.    QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

The information called for by this item is provided in the Market Risk section of "MD&A," which is included in Item 2 of this Report, and is incorporated herein by reference.

ITEM 4.    CONTROLS AND PROCEDURES

EVALUATION OF DISCLOSURE CONTROLS AND PROCEDURES. FNB’s management, with the participation of our principal executive and financial officers, evaluated our disclosure controls and procedures (as defined in Rules 13a–15(e) and 15d–15(e) under the Securities Exchange Act of 1934, as amended) as of the end of the period covered by this Quarterly Report on Form 10-Q. Based on this evaluation, our management, including the Chief Executive Officer (CEO) and the Chief Financial Officer (CFO), concluded that, as of the end of the period covered by this quarterly report, our disclosure controls and procedures were effective as of such date at the reasonable assurance level as discussed below to ensure that information required to be disclosed by us in the reports we file under the Securities Exchange Act of 1934, as amended, is recorded, processed, summarized and reported within the time periods specified in the rules and forms of the SEC and that such information is accumulated and communicated to our management, including our principal executive officer and principal financial officer, as appropriate to allow timely decisions regarding required disclosure.

LIMITATIONS ON THE EFFECTIVENESS OF CONTROLS. FNB’s management, including the CEO and the CFO, does not expect that our disclosure controls and internal controls will prevent all errors and all fraud. A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within FNB have been detected. These inherent limitations include the realities that judgments in decision making can be faulty, and that breakdowns can occur because of simple error or mistake. In addition, controls can be circumvented by the individual acts of some persons, by collusion of two or more people or by management override of the controls.

CHANGES IN INTERNAL CONTROLS. The CEO and the CFO have evaluated the changes to our internal controls over financial reporting that occurred during our fiscal quarter ended March 31, 2023, as required by paragraph (d) of Rules 13a–15 and 15d–15 under the Securities Exchange Act of 1934, as amended, and have concluded that there were no such changes that materially affected, or are reasonably likely to materially affect, our internal controls over financial reporting.

PART II - OTHER INFORMATION

ITEM 1.    LEGAL PROCEEDINGS

The information required by this Item is set forth in the “Other Legal Proceedings” discussion in Note 12, "Commitments, Credit Risk and Contingencies" of the Notes to the Consolidated Financial Statements, which is incorporated herein by reference in response to this Item.

ITEM 1A.    RISK FACTORS

For information regarding risk factors that could affect our results of operations, financial condition and liquidity, see the risk factors disclosed in the “Risk Factors” section of our 2022 Annual Report on Form 10-K.

The risk factors below relate to the recent banking industry disruption, and are in addition to the risk factors previously disclosed in our 2022 Annual Report on Form 10-K.

Recent volatility in the banking sector, triggered by the failures of Silicon Valley Bank and Signature Bank, may result in legislative initiatives, agency rulemaking activities, or changes in agency policies and priorities that could subject FNB and FNBPA to enhanced government regulation and supervision.

On March 10, 2023, Silicon Valley Bank (SVB) was closed by the California Department of Financial Protection and Innovation. Two days later, on March 12, 2023, Signature Bank (SBNY) also failed. In each case, the FDIC was appointed as receiver. The FDIC, together with the FRB and the UST, then took action under applicable emergency systemic risk authority to fully protect the depositors of each bank as the institutions were wound down. SVB and SBNY each had substantial business relationships with, and exposure to, entities within the innovation sector, including financial technology and digital asset companies, and had received an influx of deposits over the course of several years which coincided with the rapid growth of that sector. In recent periods, however, SVB and SBNY each began to experience significant deposit withdrawals. These withdrawals increased rapidly in early March, ultimately causing each institution to fail as it became apparent that available sources of liquidity would be inadequate to cover the withdrawals. Subsequently on May 1, 2023 First Republic Bank (FRC) became another large bank to fail.

The SVB and SBNY bank failures and subsequent industry volatility may lead to governmental initiatives intended to prevent future bank failures and stem significant deposit outflows from the banking sector, including (i) legislation aimed at preventing similar future bank runs and failures and stabilizing confidence in the banking sector over the long term, (ii) agency rulemaking to modify and enhance relevant regulatory requirements - specifically with respect to liquidity risk management, deposit concentrations, capital adequacy, stress testing and contingency planning, and safe and sound banking practices, and (iii) enhancement of the agencies’ supervision and examination policies and priorities. More specifically, for instance, the federal banking agencies may modify the risk-based capital regulations to eliminate the ability of certain banks to offset portions of their AOCI when calculating regulatory capital requirements. Alternatively, the treatment of AOCI under GAAP also could be modified, the effect of which may carry through to banks’ capital management and regulatory compliance practices. The federal banking agencies may also re-evaluate applicable liquidity risk management standards, such as by reconsidering the mix of assets that are deemed to be “high-quality liquid assets” (HQLA) and/or how HQLA holdings and cash inflows and outflows are tabulated and weighted for liquidity management purposes.

Although we cannot predict which initiatives may be pursued by lawmakers and agency leadership, nor can we predict the terms and scope of any such initiatives, any of the potential changes referenced above could, among other things, subject us to additional material costs, limit the types of financial services and products we may offer, and limit our future growth, any of which could materially and adversely affect our business, results of operations or financial condition.

We may experience increases in FDIC insurance assessments.

The losses incurred by the DIF in connection with the resolution of SVB and SBNY, which are estimated to amount to approximately $22.5 billion in the aggregate, are required by law to be recovered through one or more special assessments on depository institutions and, potentially, their holding companies if the FDIC determines such action to be appropriate and the Secretary of the UST concurs with the FDIC’s determination. The FDIC must consider a variety of factors in determining the terms and applicability of any such special assessment, including, among others, the types of entities that benefit from the action taken by the agencies, economic conditions, and anticipated industry impacts. It is also possible that our regular deposit insurance assessment rates will increase should the FDIC alter the assessment rate schedule or calculation methodology for all larger financial institutions (including FNBPA) as a result of the recent bank failures. Although we cannot predict the specific

81

timing and terms of any special assessment relating to the resolution of SVB and SBNY, or any other increase in our deposit insurance assessment rates, any increase in our assessment fees could have a materially adverse effect on our results of operations and financial condition.

Liquidity risk could impair our ability to fund operations and meet our obligations as they become due.

Our ability to implement our business strategy will depend on our liquidity and ability to obtain funding for loan originations, working capital and other general purposes. Liquidity is needed to fund various obligations, including credit commitments to borrowers, mortgage and other loan originations, withdrawals by depositors, repayment of borrowings, dividends to shareholders, operating expenses and capital expenditures. Liquidity risk is the potential that we will be unable to meet our obligations as they come due, capitalize on growth opportunities as they arise, or pay regular dividends on our common stock because of an inability to liquidate assets or obtain adequate funding on a timely basis, at a reasonable cost and within acceptable risk tolerances. Our preferred sources for funding are deposits and customer repurchase agreements, which are low cost and stable sources of funding for us. We compete with commercial banks, savings banks and credit unions, as well as nondepository competitors such as mutual funds, fintechs, securities and brokerage firms and insurance companies, for deposits and customer repurchase agreements. If a significant portion of our deposits were to be withdrawn within a short period of time or if we are unable to attract and maintain sufficient levels of deposits and customer repurchase agreements to fund our loan growth and liquidity objectives, we may be subject to paying higher funding costs by raising interest rates that are paid on deposits and customer repurchase agreements or cause us to source funds from third-party providers which may be higher cost funding, impacting our net interest margin. Additionally, our ability to attract depositors during a time of actual or perceived distress or instability in the marketplace may be limited. Because our available-for-sale investment securities lose value when interest rates rise, after-tax proceeds resulting from the sale of such assets may be diminished during periods when interest rates are elevated. However, should we sell all or a material portion of our securities portfolio to increase liquidity in the face of depositor withdrawals in the current interest rate environment, we would be required to realize significant losses that would, in turn, reduce our regulatory capital position.

We are subject to supervision and examination by U.S. government authorities which could result in investigations, enforcement actions, fines, and other adverse effects.

The federal banking agencies, including the OCC, the CFPB, as well as the DOJ, have in recent years adopted a more aggressive enforcement posture in line with general enforcement priorities - specifically with respect to consumer protection issues and anti-discrimination lending laws. These government agencies have expressed a heightened interest in fair lending and loan servicing, mortgage loan origination and mortgage loan servicing, bank and financial institution sales practices, management of consumer accounts and the charging of overdraft and various other fees, fair credit reporting, predatory lending, debt collection, and meaningful disclosure of credit and savings terms, among others, and perform periodic reviews, examinations, and investigations in these areas. An adverse finding or outcome of any such review, examination, or investigation that involves an assertion of regulatory noncompliance or a violation of law could result in possible fines, penalties, restitution, or other forms of remediation that could have a material adverse effect on our business, financial condition, results of operations, or reputation.

In addition, the recent failures of SVB, SBNY, and FRC have further increased the regulatory focus and scrutiny of financial institutions. Congress and the federal banking agencies have begun to evaluate the events leading to the failures of SVB, SBNY and FRC to ascertain possible explanations for these developments. Preliminarily, legislators and the leadership of the federal banking agencies have posited varying theories, including, for example, inadequate prudential regulation of regional banking organizations (generally, institutions with less than $250 billion in total assets), insufficient supervision of such organizations, and a failure by the institutions themselves to properly manage risks—specifically including interest rate and liquidity risks in consideration of each institution’s business model, exposure to the innovation sector, and substantial uninsured deposit liabilities.

Further evaluation of recent developments may lead to governmental initiatives intended to prevent future bank failures and stem significant deposit outflows from the banking sector. Although we cannot predict with certainty which initiatives may be pursued by lawmakers and agency leadership, nor can we predict the terms and scope of any such initiatives, any potential changes could, among other things, subject us to additional costs, limit the types of financial services and products we may offer, and limit our future growth, any of which could materially and adversely affect our business, results of operations or financial condition.

Accounting Policies [Abstract]

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

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. Events occurring subsequent to March 31, 2023 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 2022 Annual Report on Form 10-K filed with the SEC on February 24, 2023.

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, income taxes and deferred tax assets and litigation reserves, 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 2022 Annual Report on Form 10-K.

The following table summarizes accounting pronouncements issued by the FASB that we recently adopted or will be adopting in the future.

TABLE 2.1

Standard	Description	Financial Statements Impact
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 Method	This Update expands the use of the proportional amortization method of accounting, previously only allowable for LITHC 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 will be effective as of January 1, 2024. Early adoption of this Update is permitted. We are in the process of reviewing our existing tax equity investment portfolios and assessing the potential impact to our consolidated financial statements.
Troubled Debt Restructuring and Charge-offs
ASU 2022-02, Financial Instruments – Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures	This Update eliminates the recognition and measurement guidance on TDRs for creditors that have adopted ASC 326 and requires entities to apply loan refinancing and restructuring guidance to determine whether a modification results in a new loan or a continuation of an existing loan. The Update requires enhanced disclosures for certain loan modifications by creditors when a borrower is experiencing financial difficulty if the modification includes principal forgiveness, an interest rate reduction, an other-than-insignificant payment delay, a term extension, or a combination of those modification types. This Update also requires public business entities to present current-period gross write-offs by year of origination in their vintage disclosures.	This Update is to be applied using a prospective method. For the transition method related to TDRs, an entity has the option to apply a modified retrospective transition method. We adopted this Update on January 1, 2023. Adoption of this Update did not have a material impact on our consolidated financial statements.

MERGERS AND ACQUISITIONS

Business Combination and Asset Acquisition [Abstract]

MERGERS AND ACQUISITIONS

MERGERS AND ACQUISITIONS

Howard Bancorp, Inc.

On January 22, 2022, we completed our acquisition of Howard, a bank holding company headquartered in Baltimore City, Maryland. The acquisition enhanced our presence in the Mid-Atlantic Region. Additionally, cost savings, efficiencies and other benefits were realized from the combined operations. On the acquisition date, Howard had assets with a net book value of approximately $2.4 billion, including $1.8 billion in both loans and deposits. The acquisition was valued at approximately $443 million and resulted in the issuance of 34,074,495 shares of our common stock in exchange for 18,930,329 shares of Howard common stock. We also acquired restricted stock units and the fully vested outstanding stock options of Howard.

This merger was accounted for in accordance with the acquisition method of accounting. Fair values for all assets and liabilities are presented in Table 3.1. Determining the fair value of assets and liabilities is a complex process involving significant judgment regarding estimates and assumptions used to calculate fair values. We have completed the review of valuations for the acquired assets and liabilities.

Goodwill related to the Howard acquisition was recorded in the Community Banking business segment and is not deductible for income tax purposes as the acquisition was accounted for as a tax-free exchange for tax purposes. We incurred merger expenses relating to the Howard acquisition of $28.6 million for the first three months of 2022. We did not record any merger expenses relating to the Howard acquisition in 2023.

Purchased loans and leases that reflect a more-than-insignificant deterioration of credit from origination are considered PCD. We consider various factors in connection with the identification of more-than-insignificant deterioration in credit, including but not limited to nonperforming status, delinquency, risk ratings, TDR classification, FICO scores and other qualitative factors that indicate deterioration in credit quality since origination. For PCD loans and leases, the initial estimate of expected credit losses is recognized in the ACL on the date of acquisition using the same methodology as other loans and leases held-for-investment. As part of the Howard acquisition, we acquired PCD loans and leases of $186.9 million. We established an ACL at acquisition of $10.0 million with a corresponding gross-up to the amortized cost of the PCD loans and leases. The non-credit discount on the PCD loans and leases was $5.4 million and the Day 1 fair value was $171.5 million. The initial provision expense for non-PCD loans associated with the Howard acquisition was $19.1 million.

We integrated the systems and the operating activities of Howard into FNB in February 2022. Due to that integration, it is impracticable to disclose the revenue from the Howard assets acquired and income before income taxes subsequent to the acquisition.

UB Bancorp

On December 9, 2022, we completed our acquisition of Union, a bank holding company based in Greenville, North Carolina. This acquisition further increases our presence in North Carolina and adds low-cost granular deposits which continue to be value accretive in the current economic environment. On the acquisition date, Union had assets with a net book value of approximately $1.1 billion, including $0.7 billion in loans and $1.0 billion in deposits. The acquisition was valued at approximately $126 million and resulted in the issuance of 9,672,691 shares of our common stock in exchange for 6,008,123 shares of Union common stock.

This merger was accounted for in accordance with the acquisition method of accounting. Preliminary fair values for all assets and liabilities are presented in Table 3.1. Determining the fair value of assets and liabilities is a complex process involving significant judgment regarding estimates and assumptions used to calculate fair values. Accordingly, the initial accounting for the merger is not complete.

We continue to analyze the valuations assigned to the acquired assets and assumed liabilities. Due to the complexity in valuing the loans and the significant amount of data inputs required, the valuation of the loans is not yet final. We are also assessing the valuation on deferred taxes. The valuation on acquired premises, core deposit intangibles and debt have been completed.

Goodwill related to the Union acquisition was recorded in the Community Banking business segment and is not deductible for income tax purposes as the acquisition was accounted for as a tax-free exchange for tax purposes. We incurred merger expenses relating to the Union acquisition of $2.1 million for the first three months of 2023. We recorded core deposit intangibles of $41 million which reflect the much higher cost of alternative funding given the higher interest rate environment at the time of acquisition.

Purchased loans and leases that reflect a more-than-insignificant deterioration of credit from origination are considered PCD. We consider various factors in connection with the identification of more-than-insignificant deterioration in credit, including but not limited to nonperforming status, delinquency, risk ratings, FICO scores and other qualitative factors that indicate deterioration in credit quality since origination. For PCD loans and leases, the initial estimate of expected credit losses is recognized in the ACL on the date of acquisition using the same methodology as other loans and leases held-for-investment. As part of the Union acquisition, we acquired PCD loans and leases of $36.9 million. We established an ACL at acquisition of $1.8 million with a corresponding gross-up to the amortized cost of the PCD loans and leases. The non-credit discount on the PCD loans and leases was $0.5 million and the Day 1 fair value was $34.7 million. The initial provision expense for non-PCD loans associated with the Union acquisition was $9.4 million.

We integrated the systems and the operating activities of Union in December 2022. Due to that integration, it is impracticable to disclose the revenue from the Union assets acquired and income before income taxes subsequent to the acquisition.

The following table summarizes the amounts recorded on the consolidated balance sheets as of the acquisition dates in conjunction with the Howard and Union acquisitions discussed above.

The amortized cost and fair value of AFS debt securities are presented in the table below. There was no ACL in the AFS portfolio at March 31, 2023 and December 31, 2022. Accrued interest receivable on AFS debt securities totaled $8.9 million at both March 31, 2023 and December 31, 2022, 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 the amortized cost basis of AFS debt securities.

The ACL for the HTM portfolio was $0.32 million and $0.23 million at March 31, 2023 and December 31, 2022, respectively. Accrued interest receivable on HTM debt securities totaled $13.6 million and $14.0 million at March 31, 2023 and December 31, 2022, respectively, 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 the amortized cost basis of HTM debt securities.

There were no significant gross gains or gross losses realized on securities during the three months ended March 31, 2023 or 2022. Unrealized losses on the AFS and HTM portfolios are due to the increase in market interest rates with 84.9% of these securities backed or sponsored by the U.S. government as of March 31, 2023.

We evaluated the AFS debt securities that were in an unrealized loss position at March 31, 2023. Based on the credit ratings and implied government guarantee for these securities, we concluded the loss position is temporary and caused by the significant movement of interest rates since 2022 and does not reflect any expected credit losses. We do not intend to sell these

AFS debt securities and it is not more likely than not that we will be required to sell these securities before the recovery of their amortized cost basis.

Credit Quality Indicators

We use credit ratings and the most recent financial information to help evaluate the credit quality of our credit-related AFS and HTM securities portfolios. Management reviews the credit profile of each issuer on an annual basis, and more frequently as needed. Based on the nature of the issuers and current conditions, we have determined that securities backed by the UST, Fannie Mae, Freddie Mac, FHLB, Ginnie Mae, and the SBA have zero expected credit loss.

Our municipal bond portfolio, with a carrying amount of $1.1 billion as of March 31, 2023 is highly rated with an average rating of AA and 100% of the portfolio having an A or better rating. All of the securities in the municipal portfolio are general obligation bonds. Geographically, municipal bonds support our primary footprint as 60% of the securities are from municipalities located in the primary states within which we conduct business. The average holding size of the securities in the municipal bond portfolio is $2.5 million. In addition to the strong stand-alone ratings, 60% of the municipal bonds have some formal credit enhancement (e.g., insurance) that strengthens the creditworthiness of the bond.

The ACL on the HTM municipal bond portfolio is calculated on each bond using:

•The bond’s underlying credit rating, time to maturity and exposure amount;

•Credit enhancements that improve the bond’s credit rating (e.g., insurance); and

•Moody’s U.S. Bond Defaults and Recoveries, 1970-2021 study.

By using these components, we derive the expected credit loss on the HTM general obligation municipal bond portfolio. We further refine the expected credit loss by factoring in economic forecast data using our Commercial and Industrial Non-Manufacturing loan portfolio forecast adjustment as derived through our assessment of the loan portfolio as a proxy for our municipal bond portfolio.

Our corporate bond portfolio, with a carrying amount of $36.1 million as of March 31, 2023 primarily consists of subordinated debentures of banks within our footprint. The average holding size of the securities in the corporate bond portfolio is $2.4 million.

The ACL on the HTM corporate bond portfolio is calculated using:

•The bond’s credit rating, time to maturity and exposure amount;

•Moody’s Annual Default Study, 03/13/2023; and

•Most recent financial statements.

By using these components, we derive the expected credit loss on the HTM corporate bond portfolio. We further refine the expected credit loss by factoring in economic forecast data using our bank-wide loan portfolio forecast adjustment as derived through our assessment of the Bank's loan portfolio as a proxy for our corporate bond portfolio.

For the year-to-date periods ending March 31, 2023 and 2022, we had no significant provision expense and no charge-offs or recoveries. The ACL on the HTM portfolio was $0.32 million, consisting of $0.07 million relating to the municipal bond portfolio and $0.25 million relating to other debt securities, as of March 31, 2023, and $0.07 million relating to the municipal bond portfolio and $0.16 million relating to other debt securities as of December 31, 2022. The AFS securities portfolios did not have an ACL at March 31, 2023 or December 31, 2022 and there were no securities that were past due or on non-accrual at either date.

LOANS AND LEASES

LOANS AND LEASES

Accrued interest receivable on loans and leases, which totaled $100.4 million at March 31, 2023 and $99.3 million at December 31, 2022, is excluded from the estimate of credit losses and assessed separately in other assets in the Consolidated Balance Sheets for both periods and not included in the following tables.

Loans and Leases by Portfolio Segment

Following is a summary of total loans and leases, net of unearned income:

TABLE 5.1

(in millions)	March 31, 2023		December 31, 2022
Commercial real estate	$	11,528	$	11,526

Total consumer loans	11,161		10,965
Total loans and leases, net of unearned income	$	30,673	$	30,255

The remaining accretable discount included in the amortized cost of acquired loans was $54.5 million and $58.6 million at March 31, 2023 and December 31, 2022, respectively, which includes $10.1 million and $30.9 million established for Howard and Union, respectively, at the time of acquisition.

The loans and leases portfolio categories are comprised of the following types of loans, where in each case the LGD is dependent on the nature and value of the respective collateral:

•Commercial real estate includes both owner-occupied and non-owner-occupied loans secured by commercial properties where operational cash flows on owner-occupied properties or rents received by our borrowers from their tenant(s) on both a property and global basis are the primary default risk drivers, including rents paid by stand-alone business customers for owner-occupied properties;

•Commercial and industrial includes loans to businesses that are not secured by real estate where the borrower's leverage and cash flows from operations are the primary default risk drivers;

•Commercial leases consist of leases for new or used equipment where the borrower's cash flow from operations is the primary default risk driver;

•Other is comprised primarily of credit cards and mezzanine loans where the borrower's cash flow from operations is the primary default risk driver;

•Direct installment is comprised of fixed-rate, closed-end consumer loans for personal, family or household use, such as home equity loans and automobile loans where the primary default risk driver is the borrower's employment status and income;

•Residential mortgages consist of conventional and jumbo mortgage loans for 1-4 family properties where the primary default risk driver is the borrower's employment status and income;

•Indirect installment is comprised of loans originated by approved third parties and underwritten by us, primarily automobile loans where the primary default risk driver is the borrower's employment status and income; and

•Consumer lines of credit include home equity lines of credit and consumer lines of credit that are either unsecured or secured by collateral other than home equity where the primary default risk driver is the borrower's employment status and income.

The loans and leases portfolio consists principally of loans to individuals and small- and medium-sized businesses within our primary market in seven states and the District of Columbia. Our primary 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.

The following table shows occupancy information relating to commercial real estate loans:

Credit Quality

We monitor the credit quality of our loan portfolio using several performance measures based on payment activity and borrower performance. We use an internal risk rating assigned to a commercial loan or lease at origination, summarized below.

TABLE 5.3

Rating Category	Definition
Pass	in general, the condition of the borrower and the performance of the loan is satisfactory or better
Special Mention	in general, the condition of the borrower has deteriorated, requiring an increased level of monitoring
Substandard	in general, the condition of the borrower has significantly deteriorated and the performance of the loan could further deteriorate if deficiencies are not corrected
Doubtful	in general, the condition of the borrower has significantly deteriorated and the collection in full of both principal and interest is highly questionable or improbable

The use of these internally assigned credit quality categories within the commercial loan and lease portfolio permits our use of transition matrices to establish a basis which is then impacted by quantitative inputs from our econometric model forecasts over the R&S period. Our internal credit risk grading system is based on past experiences with similarly graded loans and leases and conforms to regulatory categories. In general, loan and lease risk ratings within each category are reviewed on an ongoing basis according to our policy for each class of loans and leases. Each quarter, we analyze the resulting ratings, as well as other external statistics and factors such as delinquency, to track the migration performance of the commercial loan and lease portfolio. Loans and leases within the Pass credit category or that migrate toward the Pass credit category generally have a lower risk of loss compared to loans and leases that migrate toward the Substandard or Doubtful credit categories. Accordingly, we apply higher risk factors to Substandard and Doubtful credit categories.

The following table summarize the designated loan rating category by loan class including term loans on an amortized cost basis by origination year and year-to-date gross charge-offs by originating year:

We use delinquency transition matrices within the consumer and other loan classes to establish the basis for the R&S forecast portion of the credit risk. Each month, management analyzes payment and volume activity, FICO scores and Debt-to-Income (DTI) scores and other external factors such as unemployment, to determine how consumer loans are performing.

The carrying value of residential-secured consumer OREO held as a result of obtaining physical possession upon completion of a foreclosure or through completion of a deed in lieu of foreclosure amounted to $1.0 million at March 31, 2023 and $1.1 million at December 31, 2022. The recorded investment of residential-secured consumer OREO for which formal foreclosure proceedings are in process at March 31, 2023 and December 31, 2022 totaled $14.4 million and $11.8 million, respectively.

Approximately $49.0 million of commercial loans are collateral dependent at March 31, 2023. Repayment is expected to be substantially through the operation or sale of the collateral on the loan. These loans are primarily secured by business assets or commercial real estate.

Loan Modifications

During the period, there are loans whose contractual terms have been modified in a manner that grants a concession to a borrower experiencing financial difficulties. These modifications typically result from loss mitigation activities and could include a term extension, interest rate reduction, principal forgiveness and other actions intended to minimize the economic loss and to avoid foreclosure or repossession of collateral. Accrued interest receivable on loan modifications totaled $0.02 million at March 31, 2023, and is excluded from the amortized cost of loan modifications in the tables below.

The following table shows the amortized cost basis at the end of the reporting period of the loans modified to borrowers experiencing financial difficulty, disaggregated by class of financing receivable, type of concession granted and the financial effect of the modifications made to borrowers experiencing financial difficulty:

Some loan modifications may not ultimately result in the full collection of principal and interest, as modified, and may result in potential incremental losses which are factored into the ACL. There were no additional funds committed to borrowers whose loans were modified during the first three months of 2023.

Commercial loans over $1.0 million whose terms have been modified are generally placed on non-accrual, individually analyzed and measured based on the fair value of the underlying collateral. Our ACL includes specific reserves for commercial loans modified. There was $1.6 million and no specific reserve for commercial loans modified at March 31, 2023 and December 31, 2022, respectively, and pooled reserves for individual loans of $1.1 million and $1.1 million for those same periods, respectively, based on loan segment LGD. Upon default, the amount of the recorded investment of the modified loan balance in excess of the fair value of the collateral, less estimated selling costs, is generally considered a confirmed loss and is charged-off against the ACL.

All other classes of loans whose terms have been modified are pooled and measured based on the loan segment LGD. Our ACL included pooled reserves for these classes of loans of $3.7 million for March 31, 2023 and $3.8 million for December 31, 2022. Upon default of an individual loan, our charge-off policy is followed for that class of loan.

Following is a summary of loans modified in a manner that grants a concession to a borrower experiencing financial difficulties, by class, for which there was a payment default, excluding loans that have been paid off and/or sold. Default occurs when a loan is 90 days or more past due or in non-accrual and is within 12 months of restructuring.

ALLOWANCE FOR CREDIT LOSSES ON LOANS AND LEASES

ALLOWANCE FOR CREDIT LOSSES ON LOANS AND LEASESThe ACL is maintained for credit losses expected in the existing loan and lease portfolio and is presented as a reserve against loans and leases on the Consolidated Balance Sheets. Loan and lease losses are charged off against the ACL, with recoveries of amounts previously charged off credited to the ACL. Provisions for credit losses are charged to operations based on management’s periodic evaluation of the appropriate level of the ACL.

Following is a summary of changes in the ACL, by loan and lease class:

The model used to calculate the ACL is dependent on the portfolio composition and credit quality, as well as historical experience, current conditions and forecasts of economic conditions and interest rates. Specifically, the following considerations are incorporated into the ACL calculation:

•a third-party macroeconomic forecast scenario;

•a 24-month R&S forecast period for macroeconomic factors with a reversion to the historical mean on a straight-line basis over a 12-month period; and

•the historical through-the-cycle mean was calculated using an expanded period to include a prior recessionary period.

At March 31, 2023 and December 31, 2022, we utilized a third-party consensus macroeconomic forecast reflecting the current and projected macroeconomic environment. For our ACL calculation at March 31, 2023, the macroeconomic variables that we utilized included, but were not limited to: (i) the purchase only Housing Price Index, which declines 2.5% over our R&S forecast period, (ii) a Commercial Real Estate Price Index, which declines 4.6% over our R&S forecast period, (iii) S&P Volatility, which decreases 39.7% in 2023 and 10.5% in 2024 and (iv) bankruptcies, which increase steadily over the R&S forecast period but average below historical levels. Macroeconomic variables that we utilized for our ACL calculation as of December 31, 2022 included, but were not limited to: (i) the purchase only Housing Price Index, which declines 3.7% over our R&S forecast period, (ii) a Commercial Real Estate Price Index, which declines 0.9% over our R&S forecast period, (iii) S&P Volatility, which decreases 41.0% in 2023 and 8.1% in 2024 and (iv) bankruptcies, which increase steadily over the R&S forecast period but average below historical levels.

The ACL on loans and leases of $403.4 million at March 31, 2023 increased $1.7 million, or 0.4%, from December 31, 2022. Our ending ACL coverage ratio at March 31, 2023 was 1.32%, compared to 1.33% at December 31, 2022. Total provision for credit losses for the three months ended March 31, 2023 was $14.1 million compared to $18.0 million for the same period of 2022. Provision was primarily due to loan growth, CECL-related model impacts from forecasted macroeconomic conditions and charge-off activity. The first quarter of 2023 reflected net charge-offs of $13.2 million, or 0.18% annualized of average total loans, compared to $1.9 million, or 0.03% annualized, in the first quarter of 2022.

Fair value, end of period	67.8		58.2

We had no valuation allowance for MSRs as of March 31, 2023 or December 31, 2022.

The fair value of MSRs is highly sensitive to changes in assumptions and is determined by estimating the present value of the asset’s future cash flows utilizing market-based prepayment rates, discount rates and other assumptions validated through comparison to trade information, industry surveys and the use of independent third-party valuations. Changes in prepayment speed assumptions have the most significant impact on the fair value of MSRs. Generally, as interest rates decline, mortgage loan prepayments accelerate due to increased refinance activity, which results in a decrease in the fair value of MSRs and as interest rates increase, mortgage loan prepayments decline, which results in an increase in the fair value of MSRs. Measurement of fair value is limited to the conditions existing and the assumptions utilized as of a particular point in time, and those assumptions may not be appropriate if they are applied at a different point in time.

Following is a summary of the sensitivity of the fair value of MSRs to changes in key assumptions:

TABLE 7.4

(dollars in millions)	March 31, 2023			December 31, 2022
Weighted average life (months)	95			96
Constant prepayment rate (annualized)	7.5		%	7.3		%

-0.50%	(3)			(3)
-1.00%	(7)			(6)
-2.00%	(18)			(15)

The sensitivity calculations above are hypothetical and should not be considered to be predictive of future performance. Changes in fair value based on adverse changes in assumptions generally cannot be extrapolated because the relationship of the changes in assumptions to fair value may not be linear. Also, in this table, the effects of an adverse variation in a particular assumption on the fair value of MSRs is calculated without changing any other assumptions, while, in reality, changes in one factor may result in changing another, which may magnify or contract the effect of the change.

LEASES

We have operating leases primarily for certain branches, office space, land and office equipment. We have finance leases for certain branches. Our operating leases expire at various dates through the year 2046 and generally include one or more options to renew. Our finance leases expire at various dates through the year 2051 and generally include one or more options to renew. The exercise of lease renewal options is at our sole discretion. As of March 31, 2023, we had operating lease right-of-use assets and operating lease liabilities of $135.1 million and $145.2 million, respectively. We have finance lease right-of-use assets and finance lease liabilities of $25.5 million and $26.2 million, respectively.

Our operating lease agreements do not contain any material residual value guarantees or material restrictive covenants. As of March 31, 2023, we have certain operating lease agreements, primarily for administrative office space, that have not yet commenced. At commencement, it is expected that these leases will add approximately $76.4 million in right-of-use assets and $97.8 million in other liabilities. These operating leases are currently expected to commence throughout the remainder of 2023 with lease terms of up to 21 years. These operating leases include the lease, with a related party, of the future new FNB headquarters building in Pittsburgh, Pennsylvania. The related party operating lease is accounted for in a manner consistent with all other leases on the basis of the legally enforceable terms and conditions of the lease and the related party represents a VIE for which we are not the primary beneficiary.

VARIABLE INTEREST ENTITIES

VARIABLE INTEREST ENTITIES

We evaluate our interest in certain entities to determine if these entities meet the definition of a VIE and whether we are the primary beneficiary and required to consolidate the entity based on the variable interest we held both at inception and when there is a change in circumstances that requires a reconsideration.

Unconsolidated VIEs

The following table provides a summary of the assets and liabilities included in our Consolidated Financial Statements, as well as the maximum exposure to losses, associated with our interests related to VIEs for which we hold an interest, but are not the primary beneficiary, at March 31, 2023 and December 31, 2022.

Trust-Preferred Securities

We have certain wholly-owned trusts whose assets, liabilities, equity, income and expenses are not included within our Consolidated Financial Statements. These trusts have been formed for the sole purpose of issuing TPS, from which the proceeds are then invested in our junior subordinated debentures, which are reflected in our Consolidated Balance Sheets as subordinated notes. The TPS are the obligations of the trusts, and as such, are not consolidated within our Consolidated Financial Statements. For additional information relating to our TPS, see Note 10, “Borrowings” in the Notes to Consolidated Financial Statements.

Each issue of the junior subordinated debentures has an interest rate equal to the corresponding TPS distribution rate. We have the right to defer payment of interest on the debentures at any time, or from time-to-time for a period not exceeding five years provided that no extension period may extend beyond the stated maturity of the related debentures. During any such extension period, distributions to the TPS will also be deferred and our ability to pay dividends on our common stock will be restricted. Periodic cash payments and payments upon liquidation or redemption with respect to TPS are guaranteed by us to the extent of funds held by the trusts. The guarantee ranks subordinate and junior in right of payment to all of our indebtedness to the same extent as the junior subordinated debt. The guarantee does not place a limitation on the amount of additional indebtedness that may be incurred by us.

Affordable Housing Tax Credit Partnerships

We make equity investments as a limited partner in various partnerships that sponsor affordable housing projects utilizing the LIHTC pursuant to Section 42 of the Internal Revenue Code. The purpose of these investments is to support initiatives

associated with the Community Reinvestment Act while earning a satisfactory return. The activities of these LIHTC partnerships include the development and operation of multi-family housing that is leased to qualifying residential tenants. These partnerships are generally located in communities where we have a banking presence and meet the definition of a VIE; however, we are not the primary beneficiary of the entities, as the general partner or managing member has both the power to direct the activities that most significantly impact the economic performance of the entities and the obligation to absorb losses beyond our own equity investment. We record our investment in LIHTC partnerships as a component of other assets and use the proportional amortization method to account for our investments in LIHTC partnerships. Amortization related to our LIHTC investments is recorded on a net basis as a component of the provision for income taxes on the Consolidated Statements of Income.

The following table presents the balances of our affordable housing tax credit investments and related unfunded commitments:

TABLE 10.1

(in millions)	March 31, 2023		December 31, 2022
Securities sold under repurchase agreements	$	255	$	317
Federal Home Loan Bank advances	1,600		930
Federal funds purchased	175		—
Subordinated notes	119		125
Total short-term borrowings	$	2,149	$	1,372

Borrowings with original maturities of one year or less are classified as short-term. Securities sold under repurchase agreements are comprised of customer repurchase agreements, which are sweep accounts with next-day maturities utilized by larger commercial customers to earn interest on their funds. Securities are pledged to these customers in an amount at least equal to

the outstanding balance. Of the total short-term FHLB advances, 9.4% had overnight maturities as of March 31, 2023. We did not have any short-term FHLB advances with overnight maturities as of December 31, 2022. At March 31, 2023, $800.0 million, or 50.0%, of the short-term FHLB advances were swapped to fixed rates with various maturities through 2024. This compares to $930.0 million, or 100.0%, as of December 31, 2022.

Following is a summary of long-term borrowings:

Junior subordinated debt	72		72
Other subordinated debt	303		303
Total long-term borrowings	$	1,298	$	1,093

During the third quarter of 2022, we completed a debt offering in which we issued $350 million aggregate principal amount of 5.150% fixed-rate senior notes due in 2025. The net proceeds of the debt offering after deducting underwriting discounts and commissions and offering costs were $347.4 million. These proceeds were used for general corporate purposes, which included the repayment of $300 million in 2.200% Senior Notes that matured in February 2023, and may also include investments at the holding company level, capital to support the growth of FNBPA and refinancing of outstanding indebtedness.

During 2022, we assumed $25 million of other subordinated debt and $5 million of junior subordinated debt from the Howard acquisition and $31 million of other subordinated debt from the Union acquisition. Those additions are reflected in the balances above and in the tables below.

Our banking affiliate has available credit with the FHLB of $10.5 billion, of which $2.1 billion was utilized and included in short-term and long-term borrowings and $590.0 million was utilized for a letter of credit for pledging of public funds as of March 31, 2023. These advances are secured by loans collateralized by residential mortgages, home equity lines of credit, commercial real estate and FHLB stock and the short-term borrowings are scheduled to mature in various amounts periodically during 2023 while the long-term borrowings are scheduled to mature in 2025. Effective interest rates paid on the long-term FHLB advances held during 2023 ranged from 4.55% to 4.69% for the three months ended March 31, 2023. There were no long-term FHLB borrowings during the first three months of 2022, or as of December 31, 2022.

The following table provides information relating to our senior notes and other subordinated debt as of March 31, 2023. The subordinated notes are eligible for treatment as tier 2 capital for regulatory capital purposes.

(6) After deducting underwriting discounts and commissions and offering costs. For the debt assumed from acquisitions, this is the fair value of the debt at the time of the acquisition.

The junior subordinated debt is comprised of the debt securities issued by FNB, or companies we acquired, in relation to our four unconsolidated subsidiary trusts (collectively, the Trusts), which are unconsolidated VIEs, and are included on the Consolidated Balance Sheets in long-term borrowings. Since third-party investors are the primary beneficiaries, the Trusts are not consolidated in our Financial Statements. We record the distributions on the junior subordinated debt issued to the Trusts as interest expense.

DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES

DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES

We are exposed to certain risks arising from both our business operations and economic conditions. We principally manage our exposures to a wide variety of business and operational risks through management of our core business activities. We manage economic risks, including interest rate risk, primarily by managing the amount, source, and duration of our assets and liabilities, and through the use of derivative instruments. Derivative instruments are used to reduce the effects that changes in interest rates may have on net income and cash flows. We also use derivative instruments to facilitate transactions on behalf of our customers.

All derivatives are carried on the Consolidated Balance Sheets at fair value and do not take into account the effects of master netting arrangements we have with other financial institutions. Credit risk is included in the determination of the estimated fair value of derivatives. Derivative assets are reported in the Consolidated Balance Sheets in other assets and derivative liabilities are reported in other liabilities. Changes in fair value are recognized in earnings except for certain changes related to derivative instruments designated as part of a cash flow hedging relationship, which are recognized in other comprehensive income.

The following table presents notional amounts and gross fair values of our derivative assets and derivative liabilities which are not offset in the Consolidated Balance Sheets:

TABLE 11.1

Total	$	13,759	$	83	$	324	$	13,718	$	96	$	411

Certain derivative exchanges have enacted a rule change which in effect results in the legal characterization of variation margin payments for certain derivative contracts as settlement of the derivatives mark-to-market exposure and not collateral. Accordingly, we have changed our reporting of certain derivatives to record variation margin on trades cleared through these exchanges as settled.  The daily settlement of the derivative exposure does not change or reset the contractual terms of the instrument.

We adopted Reference Rate Reform (RRR) on October 1, 2020, and the guidance will be followed until the Update terminates on December 31, 2024. As of October 16, 2020, we changed our valuation methodology to reflect changes made by central clearinghouses that changed the discounting methodology and interest calculation of cash migration from overnight index swap (OIS) to SOFR for U.S. dollar cleared interest rate swaps to better reflect prices obtainable in the markets in which we transact. Certain of these valuation methodology changes were applied to eligible hedging relationships. Accordingly, we have updated our hedge documentation to reflect the election of certain expedients and exceptions related to our cash flow hedging programs. The change in valuation methodology was applied prospectively as a change in accounting estimate and did not have a material impact on our consolidated financial position or results of operations.

Derivatives Designated as Hedging Instruments under GAAP

Interest Rate Contracts. We entered into interest rate derivative agreements to modify the interest rate characteristics of certain commercial loans and certain of our FHLB advances from variable rate to fixed rate in order to reduce the impact of changes in future cash flows due to market interest rate changes. These agreements are designated as cash flow hedges, hedging the exposure to variability in expected future cash flows. The derivative’s gain or loss, including any ineffectiveness, is initially reported as a component of other comprehensive income and subsequently reclassified into earnings in the same line item associated with the forecasted transaction when the forecasted transaction affects earnings.

The following table shows amounts reclassified from AOCI:

TABLE 11.2

Amount of gain (loss) reclassified from AOCI into net income	(10)		6		2		(4)

As of March 31, 2023, the maximum length of time over which forecasted interest cash flows are hedged is 3.1 years. In the twelve months that follow March 31, 2023, we expect to reclassify from the amount currently reported in AOCI net derivative losses of $23.9 million ($18.5 million net of tax), in association with interest on the hedged loans and FHLB advances. This amount could differ from amounts actually recognized due to changes in interest rates, hedge de-designations, and the addition of other hedges subsequent to March 31, 2023.

There were no components of derivative gains or losses excluded from the assessment of hedge effectiveness related to these cash flow hedges. Also, during the three months ended March 31, 2023 and 2022, there were no gains or losses from cash flow hedge derivatives reclassified to earnings because it became probable that the original forecasted transactions would not occur.

Derivatives Not Designated as Hedging Instruments under GAAP

A description of interest rate swaps, interest rate lock commitments, forward delivery commitments and credit risk contracts can be found in Note 16, "Derivative Instruments and Hedging Activities" in the Consolidated Financial Statements included in our 2022 Annual Report on Form 10-K filed with the SEC on February 24, 2023.

Interest rate swap agreements with loan customers and with the offsetting counterparties are reported at fair value in other assets and other liabilities on the Consolidated Balance Sheets with any resulting gain or loss recorded in current period earnings as other income or other expense.

Risk participation agreements sold with notional amounts totaling $483.7 million as of March 31, 2023 have remaining terms ranging from one month to eighteen years. Under these agreements, our maximum exposure assuming a customer defaults on their obligation to perform under certain derivative swap contracts with third parties would be $0.2 million at March 31, 2023 and $0.1 million at December 31, 2022. The fair values of risk participation agreements purchased and sold were $0.1 million and $0.2 million, respectively, at March 31, 2023 and $0.1 million and $0.1 million, respectively at December 31, 2022.

The following table presents the effect of certain derivative financial instruments on the Consolidated Statements of Income:

Counterparty Credit Risk

We are party to master netting arrangements with most of our swap derivative dealer counterparties. Collateral, usually marketable securities and/or cash, is exchanged between FNB and our counterparties, and is generally subject to thresholds and transfer minimums. For swap transactions that require central clearing, we post cash and securities to our clearing agency. Collateral positions are settled or valued daily, and adjustments to amounts received and pledged by us are made as appropriate to maintain proper collateralization for these transactions.

Certain master netting agreements contain provisions that, if violated, could cause the counterparties to request immediate settlement or demand full collateralization under the derivative instrument. If we had breached our agreements with our derivative counterparties we would be required to settle our obligations under the agreements at the termination value and would be required to pay nothing as of March 31, 2023 and an additional $0.1 million as of December 31, 2022, in excess of amounts previously posted as collateral with the respective counterparty.

Commitments and Contingencies Disclosure [Abstract]

COMMITMENTS, CREDIT RISK AND CONTINGENCIES

COMMITMENTS, CREDIT RISK AND CONTINGENCIES

We have commitments to extend credit and standby letters of credit that involve certain elements of credit risk in excess of the amount stated in the Consolidated Balance Sheets. Our exposure to credit loss in the event of non-performance by the customer is represented by the contractual amount of those instruments. The credit risk associated with commitments to extend credit and standby letters of credit is essentially the same as that involved in extending loans and leases to customers and is subject to normal credit policies. Since many of these commitments expire without being drawn upon, the total commitment amounts do not necessarily represent future cash flow requirements.

Following is a summary of off-balance sheet credit risk information:

TABLE 12.1

(in millions)	March 31, 2023		December 31, 2022
Commitments to extend credit	$	13,009	$	13,250
Standby letters of credit	229		207

At March 31, 2023, funding of 73.7% of the commitments to extend credit was dependent on the financial condition of the customer. We have the ability to withdraw such commitments at our discretion. Commitments generally have fixed expiration

dates or other termination clauses and may require payment of a fee. Based on management’s credit evaluation of the customer, collateral may be deemed necessary. Collateral requirements vary and may include accounts receivable, inventory, property, plant and equipment and income-producing commercial properties.

Standby letters of credit are conditional commitments issued by us that may require payment at a future date. The credit risk involved in issuing letters of credit is actively monitored through review of the historical performance of our portfolios.

Our AULC for commitments that are not unconditionally cancellable, which is included in other liabilities on the Consolidated Balance Sheets, was $20.5 million at March 31, 2023 and $21.4 million at December 31, 2022. Additional information relating to the AULC is provided in Note 6, "Allowance for Credit Losses on Loans and Leases" in the Notes to Consolidated Financial Statements.

In addition to the above commitments, subordinated notes issued by FNB Financial Services, LP, a wholly-owned finance subsidiary, are fully and unconditionally guaranteed by FNB. These subordinated notes are included in the summaries of short-term borrowings and long-term borrowings in Note 10, “Borrowings” in the Notes to Consolidated Financial Statements.

Other Legal Proceedings

In the ordinary course of business, we may assert claims in legal proceedings against another party or parties, and we are routinely named as defendants in, or made parties to, pending and potential legal actions. Also, as regulated entities, we are subject to governmental and regulatory examinations, information-gathering requests, and may be subject to investigations and proceedings (both formal and informal). Such threatened claims, litigation, investigations, regulatory and administrative proceedings typically entail matters that are considered incidental to the normal conduct of business. Claims for significant monetary damages may be asserted in many of these types of legal actions, while claims for disgorgement, reimbursement, restitution, penalties and/or other remedial actions or sanctions may be sought in regulatory matters. In these instances, if we determine that we have meritorious defenses, we will engage in an aggressive defense. However, if management determines, in consultation with counsel, that settlement of a matter is in the best interest of FNB and our shareholders, we may do so. It is inherently difficult to predict the eventual outcomes of such matters given their complexity and the particular facts and circumstances at issue in each of these matters. However, on the basis of current knowledge and understanding, and advice of counsel, we do not believe that judgments, sanctions, settlement resolutions, regulatory actions, investigations, settlements or orders, if any, that have arisen or may arise from these matters (either individually or in the aggregate, after giving effect to applicable reserves and insurance coverage) will have a material adverse effect on our financial position or liquidity, although they could potentially have a material effect on net income in a given period.

In view of the inherent unpredictability of outcomes in litigation and governmental and regulatory matters, particularly where (i) the damages sought are indeterminate, (ii) the proceedings are in the early stages, or (iii) the matters involve novel legal theories or a large number of parties, as a matter of course, there is considerable uncertainty surrounding the timing or ultimate resolution of litigation and governmental and regulatory matters, including a possible eventual loss, fine, restitution, penalty, business or adverse reputational impact, if any, associated with each such matter. In accordance with applicable accounting guidance, we establish accruals for litigation and governmental and regulatory matters when those matters proceed to a stage where they present loss contingencies that are both probable and reasonably estimable. In such cases, there may be a possible exposure to loss in excess of any amounts accrued. We will continue to monitor such matters, including ongoing reviews, examinations, and investigations by banking regulatory agencies and other government authorities, for developments that could affect the amount of the accrual, and will adjust the accrual amount as appropriate. If the loss contingency in question is not both probable and reasonably estimable, we do not establish an accrual and the matter will continue to be monitored for any developments that would make the loss contingency both probable and reasonably estimable. We believe that our accruals for legal proceedings are appropriate and, in the aggregate, are not material to our consolidated financial position, although future accruals could have a material effect on net income in a given period.

STOCK INCENTIVE PLANS

STOCK INCENTIVE PLANS

Restricted Stock

We issue restricted stock awards to key employees under our Incentive Compensation Plan (Plan). We issue time-based awards and performance-based awards under this Plan, both of which are based on a three-year vesting period. The grant date fair value of the time-based awards is equal to the price of our common stock on the grant date. The fair value of the performance-based awards is based on a Monte-Carlo simulation valuation of our common stock as of the grant date. The assumptions used for this valuation include stock price volatility, risk-free interest rate and dividend yield. We granted 470,173 and 495,844 restricted stock units during the three months ended March 31, 2023 and 2022, respectively, including 282,106 and 297,508

performance-based restricted stock units during those same periods, respectively. As of March 31, 2023, we had available up to 8,680,887 shares of common stock to issue under this Plan, including 7,397,956 shares registered during the second quarter of 2022.

The unvested restricted stock unit awards are eligible to receive cash dividends or dividend equivalents which are ultimately used to purchase additional shares of stock and are subject to forfeiture if the requisite service period is not completed or the specified performance criteria are not met. These awards are subject to certain accelerated vesting provisions upon retirement, death, disability or in the event of a change of control as defined in the award agreements.

The following table summarizes the activity relating to restricted stock units during the periods indicated:

Stock Options

All outstanding stock options were assumed from acquisitions and are fully vested. Upon consummation of our acquisitions, all outstanding stock options issued by the acquired companies were converted into equivalent FNB stock options. We issue shares of treasury stock or authorized but unissued shares to satisfy stock options exercised.

As of March 31, 2023, we had 110,222 stock options outstanding and exercisable at a weighted average exercise price per share of $9.86, compared to 176,602 stock options outstanding and exercisable at a weighted average exercise price per share of $8.96 as of March 31, 2022.

The intrinsic value of outstanding and exercisable stock options at March 31, 2023 was $0.2 million. The aggregate intrinsic value represents the amount by which the fair value of underlying stock exceeds the option exercise price.

Income tax expense was higher in 2023 due to higher pre-tax earnings as we had merger-related expenses from the Howard and Union acquisitions in 2022. The decrease in the effective tax rate for the three months ended March 31, 2023 compared to 2022 was primarily driven by higher deduction levels from employee stock compensation vesting.

Deferred Income Taxes

Deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and tax purposes. Deferred tax assets and liabilities are measured based on the enacted tax rates that will apply in the years in which the temporary differences are expected to be recovered or paid. Net deferred tax assets were $133.7 million and $147.7 million at March 31, 2023 and December 31, 2022, respectively.

EARNINGS PER COMMON SHARE

Earnings Per Share [Abstract]

EARNINGS PER COMMON SHARE

EARNINGS PER COMMON SHARE

Basic earnings per common share is calculated by dividing net income available to common stockholders by the weighted average number of shares of common stock outstanding net of unvested shares of restricted stock.

Diluted earnings per common share is calculated by dividing net income available to common stockholders by the weighted average number of shares of common stock outstanding, adjusted for the dilutive effect of potential common shares issuable for stock options and restricted shares, as calculated using the treasury stock method. Adjustments to the weighted average number of shares of common stock outstanding are made only when such adjustments dilute earnings per common share.

The following table sets forth the computation of basic and diluted earnings per common share:

FAIR VALUE MEASUREMENTS

FAIR VALUE MEASUREMENTS

Refer to Note 26 "Fair Value Measurements" to the Consolidated Financial Statements included in our 2022 Annual Report on Form 10-K filed with the SEC on February 24, 2023 for a description of additional valuation methodologies for assets and liabilities measured at fair value on a recurring and non-recurring basis.

The following table presents the balances of assets and liabilities measured at fair value on a recurring basis:

We review fair value hierarchy classifications on a quarterly basis. Changes in the observability of the valuation attributes may result in reclassification of certain financial assets or liabilities. Such reclassifications are reported as transfers in/out of Level 3 at fair value at the beginning of the period in which the changes occur. There were no transfers of assets or liabilities between the hierarchy levels during the first three months of 2023 or 2022.

From time to time, we measure certain assets at fair value on a non-recurring basis. These adjustments to fair value usually result from the application of the lower of cost or fair value accounting or write-downs of individual assets. Valuation methodologies used to measure these fair value adjustments were described in Note 26, "Fair Value Measurements" to the Consolidated Financial Statements included in 2022 Annual Report on Form 10-K. For assets measured at fair value on a non-recurring basis still held at the Balance Sheet date, the following table provides the hierarchy level and the fair value of the related assets or portfolios:

TABLE 19.3

(in millions)	Level 1		Level 2		Level 3		Total

Collateral dependent loans	$	—	$	—	$	34	$	34
Other assets - SBA servicing asset	—		—		2		2

The fair value amounts for collateral dependent loans and OREO in the table above were estimated at a date during the three months or twelve months ended March 31, 2023 and December 31, 2022, respectively. Consequently, the fair value information presented is not necessarily as of the period’s end. Collateral dependent loans measured or re-measured at fair value on a non-recurring basis during the three months ended March 31, 2023 had a carrying amount of $29.9 million, which includes an allocated ACL of $8.8 million. The ACL includes a credit to the provision applicable to the current period fair value measurements of $6.9 million, which was included in provision for credit losses for the three months ended March 31, 2023.

SBA servicing assets measured at fair value on a non-recurring basis had a carrying value of $1.9 million. During 2023, the valuation allowance decreased $0.3 million to $1.3 million as of March 31, 2023, down from $1.6 million at December 31, 2022, which is reflected in the year-to-date provision expense.

OREO measured at fair value on a non-recurring basis during 2023 had a carrying amount of $0.6 million, which included a valuation allowance of $0.3 million, as of March 31, 2023. The valuation allowance includes a loss of $0.4 million, which was included in earnings for the three months ended March 31, 2023.

Fair Value of Financial Instruments

Refer to Note 26, "Fair Value Measurements" to the Consolidated Financial Statements included in our 2022 Annual Report on Form 10-K filed with the SEC on February 24, 2023 for a description of methods and assumptions that were used to estimate the fair value of each financial instrument.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)

3 Months Ended

Mar. 31, 2023

Accounting Policies [Abstract]

Basis of Presentation

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. Events occurring subsequent to March 31, 2023 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 2022 Annual Report on Form 10-K filed with the SEC on February 24, 2023.

Use of Estimates

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, income taxes and deferred tax assets and litigation reserves, 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 2022 Annual Report on Form 10-K.

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

Standard	Description	Financial Statements Impact
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 Method	This Update expands the use of the proportional amortization method of accounting, previously only allowable for LITHC 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 will be effective as of January 1, 2024. Early adoption of this Update is permitted. We are in the process of reviewing our existing tax equity investment portfolios and assessing the potential impact to our consolidated financial statements.
Troubled Debt Restructuring and Charge-offs
ASU 2022-02, Financial Instruments – Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures	This Update eliminates the recognition and measurement guidance on TDRs for creditors that have adopted ASC 326 and requires entities to apply loan refinancing and restructuring guidance to determine whether a modification results in a new loan or a continuation of an existing loan. The Update requires enhanced disclosures for certain loan modifications by creditors when a borrower is experiencing financial difficulty if the modification includes principal forgiveness, an interest rate reduction, an other-than-insignificant payment delay, a term extension, or a combination of those modification types. This Update also requires public business entities to present current-period gross write-offs by year of origination in their vintage disclosures.	This Update is to be applied using a prospective method. For the transition method related to TDRs, an entity has the option to apply a modified retrospective transition method. We adopted this Update on January 1, 2023. Adoption of this Update did not have a material impact on our consolidated financial statements.

The amortized cost and fair value of AFS debt securities are presented in the table below. There was no ACL in the AFS portfolio at March 31, 2023 and December 31, 2022. Accrued interest receivable on AFS debt securities totaled $8.9 million at both March 31, 2023 and December 31, 2022, 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 the amortized cost basis of AFS debt securities.
