Accounting Policies [Abstract]
Statement of Accounting Policies	Statement of Accounting Policies General The following summary of accounting and reporting policies is presented to aid the reader in obtaining a better understanding of the consolidated financial statements of First Commonwealth Financial Corporation and its subsidiaries (“First Commonwealth”) contained in this report. First Commonwealth's subsidiaries include First Commonwealth Bank ("FCB" or the "Bank"), First Commonwealth Insurance Agency, Inc. ("FCIA"), FRAMAL and First Commonwealth Financial Advisors, Inc. ("FCFA"). The financial information is presented in accordance with generally accepted accounting principles and general practice for financial institutions in the United States of America. In preparing financial statements, management is required to make estimates and assumptions that affect the reported amount of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements. In addition, these estimates and assumptions affect revenues and expenses in the financial statements and as such, actual results could differ from those estimates. Through its subsidiaries, which include a commercial bank and an insurance agency, First Commonwealth provides a full range of loan, deposit, trust, insurance and personal financial planning services primarily to individuals and small to middle market businesses in 30 counties in central and western Pennsylvania as well as throughout Ohio. First Commonwealth has determined that it has one business segment. First Commonwealth is subject to regulations of certain state and federal agencies. These regulatory agencies periodically examine First Commonwealth for adherence to laws and regulations. Basis of Presentation The accompanying Consolidated Financial Statements include the accounts of First Commonwealth previously defined above. All material intercompany transactions have been eliminated in consolidation. Certain prior period amounts have been reclassified to conform to the current period's presentation. Equity investments of less than a majority but at least 20% ownership are accounted for by the equity method and classified as “Other assets.” Earnings on these investments are reflected in “Other income” on the Consolidated Statements of Income, as appropriate, in the period earned. Investment Securities Debt securities that First Commonwealth has the positive intent and ability to hold to maturity are classified as securities held to maturity and are reported at amortized cost adjusted for amortization of premium and accretion of discount on a level yield basis. Debt and equity securities that are bought and held principally for the purpose of selling them in the near term are to be classified as trading securities and reported at fair value, with unrealized gains and losses included in earnings. Debt securities not classified as either held-to-maturity securities or trading securities are classified as securities available for sale and are reported at fair value, with unrealized gains and losses that are not related to impairment excluded from earnings and reported as a component of other comprehensive income, which is included in shareholders’ equity, net of deferred taxes. First Commonwealth has securities classified as held to maturity and available for sale and does not engage in trading activities. First Commonwealth utilizes the specific identification method to determine the net gain or loss on debt securities and the average cost method to determine the net gain or loss on the equity securities. First Commonwealth conducts a comprehensive review of the investment portfolio on a quarterly basis to evaluate for expected credit losses. When evaluating available-for-sale securities, management first considers whether we intend to sell the security, or if it is more likely than not that we will be required to sell the security before recovery of its amortized cost basis. If there is intent to sell, the security's amortized cost is written down to fair value through income. Otherwise, available-for-sale securities whose market values have fallen below their book value are evaluated at the issuer-specific level to determine if the decline in value is a result of credit losses. Issuer-specific securities include obligations of U.S. Government agencies and sponsored enterprises, single issue trust preferred securities, corporate debentures and obligations of states and political subdivisions. Further analysis of these securities includes a review of research reports, analysts’ recommendations, credit rating changes, news stories, annual reports, impact of interest rate changes and any other relevant information pertaining to the affected security. Any loss not determined to be a credit loss is recorded as a reduction to shareholders equity, through other comprehensive income. Held-to-maturity securities are evaluated for impairment on an annual basis, using historical probability of default and loss given default information specific to the investment category. On a quarterly basis, a qualitative review is completed incorporating changes to the mix and credit quality of the investment portfolio. If this evaluation determines that credit losses exist an allowance for credit loss is recorded and included in earnings as a component of credit loss expense. Mortgage Loans Held for Sale Certain residential mortgage loans are originated for sale in the secondary mortgage loan market with the majority sold with servicing rights released. These loans are classified as loans held for sale and are carried at the estimated market value on an aggregate basis. Market value is determined on the basis of rates obtained in the respective secondary market for the type of loan held for sale. Loans are generally sold at a premium or discount from the carrying amount of the loan. Such premium or discount is recognized at the date of sale. Gain or loss on the sale of loans is recorded in non-interest income at the time consideration is received and all other criteria for sales treatment have been met. Loans Loans are carried at the principal amount outstanding. Interest is accrued as earned. Loans held for sale are carried at the lower of cost or fair market value determined on an individual basis. First Commonwealth considers a loan to be past due and still accruing interest when payment of interest or principal is contractually past due but the loan is both well secured and in the process of collection. For installment, mortgage, term and other loans with amortizing payments that are scheduled monthly, 90 days past due is reached when four monthly payments are due and unpaid. For demand, time and other multi-payment obligations with payments scheduled other than monthly, delinquency status is calculated using number of days instead of number of payments. Revolving credit loans, including personal credit lines and home equity lines, are considered to be 90 days past due when the borrower has not made the minimum payment for four monthly cycles. A loan is placed in nonaccrual status when, based on current information and events, it is probable that First Commonwealth will be unable to fully collect principal or interest due according to the contractual terms of the loan. A loan is also placed in nonaccrual status when, based on regulatory definitions, the loan is maintained on a “cash basis” due to the weakened financial condition of the borrower. When a determination is made to place a loan in nonaccrual status, all accrued and unpaid interest is reversed. Nonaccrual loans are restored to accrual status when, based on a sustained period of repayment by the borrower in accordance with the contractual terms of the loan, First Commonwealth expects repayment of the remaining contractual principal and interest or when the loan otherwise becomes well-secured and in the process of collection. First Commonwealth adopted ASU 2022-02 on January 1, 2023 on a prospective basis. As a result, only periods prior to this date would include loans classified as troubled debt restructured loan ("TDR"). A loan is considered to be a TDR when the loan terms have been renegotiated to provide a reduction or deferral of principal or interest as a result of the financial difficulties experienced by the borrower, who could not obtain comparable terms from alternate financing sources. During those periods, TDR loans are considered to be nonperforming loans. A loan is considered to be nonperforming when, based on current information and events, it is expected that First Commonwealth will be unable to collect principal or interest that is due in accordance with contractual terms of the loan. Expected losses on nonperforming loans are measured based on the present value of expected cash flows discounted at the loan’s effective interest rate or, as a practical expedient, at the loan’s observable market price or the fair value of the collateral if the loan is collateral dependent. For loans other than those that First Commonwealth expects repayment through liquidation of the collateral, when the remaining recorded investment in the loan is less than or equal to the present value of the expected cash flows, income is applied as a reduction to loan principal rather than interest income. Loans deemed uncollectible are charged off through the allowance for credit losses. Factors considered in assessing ultimate collectability include past due status, financial condition of the borrower, collateral values and debt covenants including secondary sources of repayment by guarantors. Payments received on previously charged off loans are recorded as recoveries in the allowance for credit losses. Acquired Loans Acquired loans are recorded at estimated fair value on the date of acquisition with no carryover of the related allowance for credit losses. The fair value of acquired loans is determined by estimating the principal and interest cash flows expected to be collected on the loans and discounting those cash flows at a market rate of interest. The estimated fair value considers factors such as loan term, internal risk rating, delinquency status, prepayment rates, estimated value of the underlying collateral and the current interest rate environment. Acquired loans are classified into two categories: PCD loans and non-PCD loans. PCD loans are defined as a loan or group of loans that have experienced more than insignificant credit deterioration since origination. Non-PCD loans will have an allowance for credit losses established on acquisition date, which is recognized as an expense through provision for credit losses. For PCD loans, an allowance for credit losses is recognized on day 1 by adding it to the fair value of the loan, which is the “Day 1 amortized cost”. There is no provision for credit loss expense recognized on PCD loans because the initial allowance for credit losses is established by grossing-up the amortized cost of the PCD loan. Loan Fees Loan origination and commitment fees, net of associated direct costs, are deferred and the net amount is amortized as an adjustment to the related loan yield on the interest method, generally over the contractual life of the related loans or commitments. Other Real Estate Owned Real estate, other than bank premises, is recorded at fair value less estimated selling costs at the time of acquisition. After that time, other real estate is carried at the lower of cost or fair value less estimated costs to sell. Fair value is determined based on an independent appraisal. Expenses related to holding the property and rental income earned on the property are generally reflected in earnings in the current period. Depreciation is not recorded on the other real estate owned properties. Allowance for Credit Losses for Loans and Leases When determining the allowance for credit losses, our loan and lease portfolio includes five primary loan categories with fourteen segments. Refer to Note 9, "Loans and Leases and Allowance for Credit Losses" for further discussion of these portfolio segments. The allowance for credit losses is calculated by pooling loans of similar credit risk characteristics and applying a discounted cash flow methodology after incorporating probability of default and loss given default estimates. Probability of default represents an estimate of the likelihood of default and loss given default measures the expected loss upon default. Inputs impacting the expected losses includes a forecast of macroeconomic factors, using a weighted forecast from a nationally recognized firm. Our model incorporates a one-year forecast of macroeconomic factors, after which the factors revert back to the historical mean over a one-year period. All nonperforming credits in excess of $250 thousand are individually evaluated on a quarterly basis. A specific reserve is established for individually evaluated loans in an amount equal to the total amount of estimated losses for the loans that are reviewed. Based on this reserve as a percentage of reviewed loan balances, a reserve is also established for the nonperforming loan balances that are not individually reviewed. An additional component of the allowance is determined by management based on a qualitative analysis of certain factors related to portfolio risks that are not incorporated in the calculated model. Factors considered by management include lending practices, ability and experience of the credit staff, the overall lending environment and external factors such as the regulatory environment and competition. Portfolio risks include unusual changes or recent trends in specific portfolios such as unexpected changes in the trends or levels of delinquency. No matter how detailed an analysis of potential credit losses is performed, these estimates are inherently imprecise. Management must make estimates using assumptions and information that is often subjective and changes rapidly. First Commonwealth made the accounting policy election to exclude accrued interest from the allowance for credit loss calculation because these balances are written off or reversed when a loan is placed in non-accrual status. Allowance for Off-Balance Sheet Credit Exposures First Commonwealth maintains an allowance for off-balance sheet credit exposure at a level deemed sufficient to absorb losses that are inherent to off-balance sheet credit risk. Off-balance sheet credit exposure includes commitments to extend credit, standby letters of credit and commercial letters of credit. The Company’s methodology for assessing the appropriateness of the allowance for off-balance sheet credit exposure consists of analysis of historical usage trends. The calculation begins with historical usage trends related to lines of credit as well as letters of credit and then utilizes those figures to determine the probable usage of available lines. These values are then adjusted by the expected loss percentage calculated for comparable loan categories as part of the allowance for credit losses for loans. This amount is adjusted quarterly and any change to the allowance is reported as part of provision expense on the Consolidated Statements of Income. The allowance for off-balance sheet credit exposures is reflected in "Other Liabilities" in the Consolidated Statements of Financial Condition. Bank Owned Life Insurance First Commonwealth and the banks that First Commonwealth has acquired have purchased insurance on the lives of certain groups of employees. The policies accumulate asset values to meet future liabilities, including the payment of employee benefits such as health care. Increases in the cash surrender value are recorded as non-interest income in the Consolidated Statements of Income and cash receipts and disbursements are included in "Operating Activities" in the Consolidated Statements of Cash Flows. Under some of these policies, the beneficiaries receive a portion of the death benefit. The net present value of the future death benefits scheduled to be paid to the beneficiaries was $3.5 million and $3.7 million as of December 31, 2023 and 2022, respectively, and is reflected in "Other Liabilities" on the Consolidated Statements of Financial Condition. Premises, Equipment and Lease Commitments Premises and equipment are carried at cost less accumulated depreciation on First Commonwealth’s Consolidated Statements of Financial Condition. Depreciation is computed on the straight-line and accelerated methods over the estimated useful life of the asset. A straight-line depreciation method was used for substantially all furniture and equipment as well as buildings and improvements. Charges for maintenance and repairs are expensed as incurred. Leasehold improvements are expensed over the term of the lease or the estimated useful life of the improvement, whichever is shorter. Software costs are amortized on a straight-line basis over a period not to exceed 7 years. A right-of-use asset and related lease liability is recognized on the Consolidated Statements of Financial Condition for operating leases First Commonwealth has entered to lease certain office facilities. These amounts are reported as components of premises and equipment and other liabilities. Short-term operating leases, which are leases with an original term of 12 months or less and do not have a purchase option that is likely to be exercised, are not recognized as part of the right-of-use asset or lease liability. First Commonwealth has no material leasing arrangements for which it is the lessor of property or equipment. Business Combinations Business combinations are accounted for by using the acquisition method of accounting. Under the acquisition method, identifiable assets acquired and liabilities assumed at the acquisition date are measured at their fair values as of that date, and are recognized separately from goodwill. The difference between the purchase price and the fair value of the net assets acquired is recorded as goodwill. Results of operations of the acquired entities are included in the Consolidated Statements of Income from the date of acquisition. Acquisition costs are expensed when incurred. Goodwill Intangible assets resulting from acquisitions under the purchase method of accounting consist of goodwill and other intangible assets (see “Other Intangible Assets” section below). Goodwill is not amortized and is subject to at least annual assessments for impairment. First Commonwealth reviews goodwill annually and again at any quarter-end if a material event occurs during the quarter that may affect goodwill. When circumstances indicate that it is more likely than not that fair value is less than carrying value, a triggering event has occurred and a quantitative impairment test is performed. Goodwill is evaluated for potential impairment by determining if our fair value has fallen below carrying value. Other Intangible Assets Other intangible assets consist of core deposits and customer lists obtained through acquisitions. Core deposit intangibles are amortized over their estimated lives using the present value of the benefit of the core deposits and straight-line methods of amortization. Customer list intangibles are amortized over the expected lives using expected cash flows based on retention of the customer base. These intangibles are evaluated for impairment on an annual basis and when events or changes in circumstances indicate that the carrying amount may not be recoverable. Accounting for the Impairment of Long-Lived Assets First Commonwealth reviews long-lived assets, such as premises and equipment and intangibles, for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. These changes in circumstances may include a significant decrease in the market value of an asset or the extent or manner in which an asset is used. If there is an indication that the carrying amount of an asset may not be recoverable, future undiscounted cash flows expected to result from the use of the asset are estimated. If the sum of the expected cash flows is less than the carrying value of the asset, a loss is recognized for the difference between the carrying value and fair value of the asset. Long-lived assets classified as held for sale are measured at the lower of their carrying amount or fair value less cost to sell. Depreciation or amortization is discontinued on long-lived assets classified as held for sale. Income Taxes First Commonwealth records taxes in accordance with the asset and liability method of FASB ASC Topic 740, “Income Taxes,” ("Topic 740") whereby deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amount of existing assets and liabilities and their respective tax bases given the provisions of the enacted tax laws. Deferred tax assets are reduced, if necessary, by the amount of such benefits that are more likely than not expected to be realized based upon available evidence. In accordance with Topic 740, interest or penalties incurred for taxes will be recorded as a component of noninterest expense. Comprehensive Income Disclosures “Other Comprehensive Income” (comprehensive income, excluding net income) includes the after-tax effect of changes in unrealized holding gains and losses on available-for-sale securities, changes in the funded status of defined benefit postretirement plans and changes in the fair value of cash flow hedges. Comprehensive income is reported in the accompanying Consolidated Statements of Comprehensive Income, net of tax. Cash and Cash Equivalents For purposes of reporting cash flows, cash and cash equivalents include cash on hand, amounts due from banks, federal funds sold and interest-bearing bank deposits. Generally, federal funds are sold for one-day periods. Derivatives and Hedging Activities First Commonwealth accounts for derivative instruments and hedging activities in accordance with FASB ASC Topic 815, “Derivatives and Hedging" ("Topic 815"). All derivatives are evaluated at inception as to whether or not they are hedging or non-hedging activities, and appropriate documentation is maintained to support the final determination. First Commonwealth recognizes all derivatives as either assets or liabilities on the Consolidated Statements of Financial Condition and measures those instruments at fair value. For derivatives designated as fair value hedges, changes in the fair value of the derivative and the hedged item related to the hedged risk are recognized in earnings. Any hedge ineffectiveness would be recognized in the income statement line item pertaining to the hedged item. For derivatives designated as cash flow hedges, changes in fair value of the effective portion of the cash flow hedges are reported in other comprehensive income ("OCI"). When the cash flows associated with the hedged item are realized, the gain or loss included in OCI is recognized in the Consolidated Statement of Income. When First Commonwealth purchases a portion of a commercial loan that has an existing interest rate swap, it enters a risk participation agreement with the counterparty and assumes the credit risk of the loan customer related to the swap. Any fee paid to First Commonwealth as a result of the risk participation agreement is offset by credit risk of the counterparties and is recognized in the income statement. Credit risk on the risk participation agreements is determined after considering the risk rating, probability of default and loss given default of the counterparties. Management periodically reviews contracts from various functional areas of First Commonwealth to identify potential derivatives embedded within selected contracts. As of December 31, 2023, First Commonwealth has interest rate derivative positions that are designated as hedging instruments and others that are not designated as hedging instruments. See Note 7, “Derivatives,” for a description of these instruments. Earnings Per Common Share Basic earnings per share excludes dilution and is computed by dividing income available to common shareholders by the weighted-average number of common shares outstanding for the period. Diluted earnings per share reflects the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock or resulted in the issuance of common stock that then shared in the earnings of the entity. For all periods presented, the dilutive effect on average shares outstanding is the result of unvested restricted stock grants. Fair Value Measurements In accordance with FASB ASC Topic 820, “Fair Value Measurements and Disclosures" ("Topic 820"), First Commonwealth groups financial assets and financial liabilities measured at fair value into three levels, based on the markets in which the assets and liabilities are traded and the reliability of the assumptions used to determine fair value. These levels are: • Level 1—Valuations for assets and liabilities traded in active exchange markets, such as the New York Stock Exchange ("NYSE"). Valuations are obtained from readily available pricing sources for market transactions involving identical assets or liabilities. • Level 2—Valuations for assets and liabilities traded in less active dealer or broker markets. Valuations are obtained for identical or comparable assets or liabilities from alternative pricing sources with reasonable levels of price transparency. Level 2 securities include U.S. Government securities issued by Agencies and Sponsored Enterprises, Obligations of States and Political Subdivisions, certain corporate securities, FHLB stock, loans held for sale, interest rate derivatives that include interest rate swaps, risk participation agreements and foreign currency contracts, certain other real estate owned and certain nonperforming loans. • Level 3—Valuations for assets and liabilities that are derived from other valuation methodologies, including option pricing models, discounted cash flow models and similar techniques, and not based on market exchange, dealer or broker traded transactions. If the inputs used to provide the evaluation are unobservable and/or there is very little, if any, market activity for the security or similar securities, the securities would be considered Level 3 securities. Level 3 valuations incorporate certain assumptions and projections in determining the fair value assigned to such assets or liabilities. The assets included in Level 3 are nonmarketable equity investments, certain other real estate owned and certain nonperforming loans. In general, fair values of financial instruments are based upon quoted market prices, where available. If such quoted market prices are not available, fair value is based upon pricing models that primarily use, as inputs, observable market-based parameters. Valuation adjustments may be made to ensure that financial instruments are recorded at fair value. These adjustments may include amounts to reflect counterparty credit quality and our creditworthiness, among other things, as well as unobservable parameters. Any such valuation adjustments are applied consistently over time. See Note 17 “Fair Values of Assets and Liabilities” for additional information. Revenue from Contracts with Customers First Commonwealth records revenue from contracts with customers in accordance with ASC Topic 606, “Revenue from Contracts with Customers” (“Topic 606”). Under Topic 606, the Company must identify the contract with a customer, identify the performance obligations in the contract, determine the transaction price, allocate the transaction price to the performance obligations in the contract, and recognize revenue when (or as) the Company satisfies a performance obligation. A significant component of the Company's revenue, net interest earned on financial assets and liabilities, is excluded from the scope of Topic 606. First Commonwealth generally fully satisfies its performance obligations on its contracts with customers as services are rendered and the transaction prices are typically fixed; charged either on a periodic basis or based on activity. Because performance obligations are satisfied as services are rendered and the transaction prices are fixed, the Company has made no significant judgments in applying the revenue guidance prescribed in Topic 606 that affect the determination of the amount and timing of revenue from contracts with customers.

Business Combination and Asset Acquisition [Abstract]
Acquisition	Acquisition On January 31, 2023, the Company completed its acquisition of Centric Financial Corporation (“Centric”) and its banking subsidiary, Centric Bank, for consideration of 9,688,478 shares of the Company's common stock. Through the acquisition, the Company obtained seven full-service banking offices and one loan production office in the Harrisburg, Philadelphia and Lancaster Metropolitan Service Areas ("MSAs"). The table below summarizes the net assets acquired (at fair value) and consideration transferred in connection with the Centric acquisition (dollars in thousands): Consideration paid Cash paid to shareholders - fractional shares $ 1 Shares issued to shareholders (9,688,478 shares) 141,355 Total consideration paid $ 141,356 Fair value of assets acquired Cash and due from banks 14,492 Investment securities 34,302 FHLB stock 7,658 Loans 923,555 Premises and equipment 17,186 Core deposit intangible 16,671 Bank owned life insurance 4,502 Other assets 17,391 Total assets acquired 1,035,757 Fair value of liabilities assumed Deposits 757,003 Borrowings 179,301 Other liabilities 18,484 Total liabilities assumed 954,788 Total fair value of identifiable net assets 80,969 Goodwill $ 60,387 The Company determined that this acquisition constitutes a business combination and therefore was accounted for using the acquisition method of accounting. Accordingly, as of the date of the acquisition, the Company recorded the assets acquired, liabilities assumed and consideration paid at fair value. The $60.4 million excess of the consideration paid over the fair value of assets acquired was recorded as goodwill and is not amortizable or deductible for tax purposes. The amount of goodwill arising from the acquisition consists largely of the synergies and economies of scale expected from combining the operations of the Company with Centric. The fair value of the 9,688,478 common shares issued was determined based on the $14.59 closing market price of the Company's common shares on the acquisition date, January 31, 2023. The valuation of the acquired assets and liabilities was completed in the second quarter of 2023. The following is a description of the valuation methodologies used to estimate the fair values of major categories of assets acquired and liabilities assumed. The Company used an independent valuation specialist to assist with the determination of fair values for certain acquired assets and assumed liabilities. Cash and due from banks - The estimated fair value was determined to approximate the carrying amount of these assets. Investment securities - The estimated fair value of the investment portfolio was based on quoted market prices, dealer quotes, and pricing obtained from independent pricing services. Loans - The estimated fair value of loans were based on a discounted cash flow methodology applied on a pooled basis for non- PCD loans and on an individual basis for PCD loans. The valuation considered underlying characteristics including loan type, term, rate, payment schedule and credit rating. Other factors included assumptions related to prepayments, probability of default and loss given default. The discount rates applied were based on a build-up approach considering the funding mix, servicing costs, liquidity premium and factors related to performance risk. Acquired loans are classified into two categories: PCD loans and non-PCD loans. PCD loans are defined as a loan or group of loans that have experienced more than insignificant credit deterioration since origination. Non-PCD loans will have an allowance established on acquisition date, which is recognized as an expense through provision for credit losses. For PCD loans, an allowance is recognized on day 1 by adding it to the fair value of the loan, which is the “Day 1 amortized cost”. There is no provision for credit loss expense recognized on PCD loans because the initial allowance is established by grossing-up the amortized cost of the PCD loan. A day 1 allowance for credit losses on non-PCD loans of $10.7 million was recorded through the provision for credit losses within the Consolidated Statements of Income. At the date of acquisition, of the $979.5 million of loans acquired from Centric, $304.7 million, or 31.1%, of Centric's loan portfolio, was accounted for as PCD loans as of February 1, 2023. Premise and equipment - The estimated fair value of land and buildings were determined by independent market-based appraisals. Core deposit intangible - The core deposit intangible was valued utilizing the cost savings method approach, which recognizes the cost savings represented by the expense of maintaining the core deposit base versus the cost of an alternative funding source. The valuation incorporates assumptions related to account retention, discount rates, deposit interest rates, deposit maintenance costs and alternative funding rates. Time deposits - The estimated fair value of time deposits was determined using a discounted cash flow approach incorporating a discount rate equal to current market interest rates offered on time deposits with similar terms and maturities. Borrowings - The estimated fair value of short-term borrowings was determined to approximate stated value. Subordinated debentures were valued using a discounted cash flow approach incorporating a discount rate that incorporated similar terms, maturities and credit ratings. The following table provides details related to the fair value of acquired PCD loans as of January 31, 2023. Unpaid Principal Balance PCD Allowance for Credit Loss at Acquisition (Discount) Premium on Acquired Loans Fair Value of PCD Loans at Acquisition (dollars in thousands) Commercial, financial, agricultural and other $ 84,095 $ (19,417) $ 117 $ 64,795 Time and demand 84,095 (19,417) 117 64,795 Real estate construction 29,947 (287) (479) 29,181 Construction other 16,978 (227) (179) 16,572 Construction residential 12,969 (60) (300) 12,609 Residential real estate 16,564 (527) (496) 15,541 Residential first lien 13,740 (197) (264) 13,279 Residential junior lien/home equity 2,824 (330) (232) 2,262 Commercial real estate 174,002 (6,971) (6,073) 160,958 Multifamily 13,169 (234) (1,413) 11,522 Non-owner occupied 97,324 (2,739) (1,902) 92,683 Owner occupied 63,509 (3,998) (2,758) 56,753 Loans to individuals 62 (3) (3) 56 Automobile and recreational vehicles 62 (3) (3) 56 Total loans and leases $ 304,670 $ (27,205) $ (6,934) $ 270,531 The following table provides details related to the fair value and Day 1 provision related to the acquired non-PCD loans as of January 31, 2023.

These amounts were expensed as incurred and are recorded as a merger and acquisition related expense in the Consolidated Statements of Income. As a result of the full integration of the operations of Centric, it is not practicable to determine revenue or net income included in the Company's operating results relating to Centric since the date of acquisition as Centric results cannot be separately identified.

Cash and Due from Banks [Abstract]
Cash and Due from Banks	Cash and Due from Banks Regulations of the Board of Governors of the Federal Reserve System impose uniform reserve requirements on all depository institutions with transaction accounts, such as checking accounts and NOW accounts. Reserves are maintained in the form of vault cash or balances held with the local Federal Reserve Bank. Because balances held at the Federal Reserve earn interest, depending on our liquidity position, we may maintain balances in excess of the reserve requirement. First Commonwealth maintained average balances of $171.0 million during 2023 and $181.6 million during 2022 with the Federal Reserve Bank of Cleveland.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivatives	Derivatives Derivatives Not Designated as Hedging Instruments First Commonwealth is a party to interest rate derivatives that are not designated as hedging instruments. These derivatives relate to interest rate swaps that First Commonwealth enters into with customers to allow customers to convert variable rate loans to a fixed rate. First Commonwealth pays interest to the customer at a floating rate on the notional amount and receives interest from the customer at a fixed rate for the same notional amount. At the same time the interest rate swap is entered into with the customer, an offsetting interest rate swap is entered into with another financial institution. First Commonwealth pays the other financial institution interest at the same fixed rate on the same notional amount as the swap entered into with the customer, and receives interest from the financial institution for the same floating rate on the same notional amount. The changes in the fair value of the swaps offset each other, except for the credit risk of the counterparties, which is determined by taking into consideration the risk rating, probability of default and loss given default for all counterparties. We have 28 risk participation agreements with financial institution counterparties for interest rate swaps related to loans in which we are a participant. The risk participation agreements provide credit protection to the financial institution should the borrower fail to perform on its interest rate derivative contract with the financial institution. We have 19 risk participation agreements with financial institution counterparties for interest rate swaps related to loans in which we are the lead bank. The risk participation agreement provides credit protection to us should the borrower fail to perform on its interest rate derivative contract with us. First Commonwealth is also party to interest rate caps and collars that are not designated as hedging instruments. The interest rate caps relate to contracts that First Commonwealth enters into with loan customers that provide a maximum interest rate on their variable rate loan. At the same time the interest rate cap is entered into with the customer, First Commonwealth enters into an offsetting interest rate cap with another financial institution. The notional amount and maximum interest rate on both interest cap contracts are identical. The interest rate collars relate to contracts that First Commonwealth enters into with loan customers that provides both a maximum and minimum interest rate on their variable rate loan. At the same time the interest rate collar is entered into with the customer, First Commonwealth enters into an offsetting interest rate collar with another financial institution. The notional amount and the maximum and minimum interest rates on both interest collar contracts are identical. The fee received, less the estimate of the loss for the credit exposure, was recognized in earnings at the time of the transaction. Derivatives Designated as Hedging Instruments In August 2019, the Company entered into two interest rate swap contracts that are designated as cash flow hedges. These contracts mature on August 15, 2024 and August 15, 2026 and have notional amounts of $30.0 million and $40.0 million, respectively. The Company's risk management objective for these hedges is to reduce its exposure to variability in expected future cash flows related to interest payments made on subordinated debentures. Initially these swaps were benchmarked to the 3-month LIBOR rate; however, as a result of the discontinuance of the LIBOR rate on June 30, 2023, both of the swap contracts were amended to hedge exposure to the variability of the 3-month CME Term SOFR. This change is in agreement with amendments made to the interest rate on the subordinated debentures as a result of the discontinuance of LIBOR. Therefore, the interest rate swaps convert the interest rate benchmark on the first $70.0 million of 3-month SOFR based subordinated debentures to a fixed rate. During 2021, the Company entered into eight interest rate swap contracts that were designated as cash flow hedges. The interest rate swaps have a total notional amount of $500.0 million; $75.0 million with an original maturity of three years, $250.0 million with an original maturity of four years, and $175.0 million with an original maturity of five years. The Company's risk management objective for these hedges is to reduce its exposure to variability in expected future cash flows related to interest payments on commercial loans. Initially these swaps were benchmarked to the 1-month LIBOR rate, however as a result of the discontinuance of the LIBOR rate on June 30, 2023, these swaps were amended to hedge exposure to the variability of the 1- month CME SOFR rate. Therefore, the interest rate swaps convert the interest payments on the first $500.0 million of 1-month SOFR based commercial loans into fixed rate payments. The periodic net settlement of these interest rate swaps are recorded as an adjustment to "Interest on subordinated debentures" or "Interest and fees on loans" in the Consolidated Statement of Income. For the years ended December 31, 2023 and 2022, net interest income decreased $19.0 million and $4.8 million, respectively, and increased $0.6 million for the year ended December 31, 2021 as a result of these interest rate swaps. Changes in the fair value of the cash flow hedges are reported on the balance sheet and in OCI. When the cash flows associated with the hedged item are realized, the gain or loss included in OCI is recognized in "Interest on subordinated debentures" or "Interest and fees on loans," in the Consolidated Statements of Income in the same line item as the income or expense on the hedged items. The cash flow hedges were highly effective at December 31, 2023 and changes in the fair value attributed to hedge ineffectiveness were not material. The Company also enters into interest rate lock commitments in conjunction with its mortgage origination business. These are commitments to originate loans whereby the interest rate on the loan is determined prior to funding and the customers have locked into that interest rate. The Company locks in the rate with an investor and commits to deliver the loan if settlement occurs (“best efforts”) or commits to deliver the locked loan in a binding (“mandatory”) delivery program with an investor. Loans under mandatory rate lock commitments are covered under forward sales contracts of mortgage-backed securities (“MBS”). Forward sales contracts of MBS are recorded at fair value with changes in fair value recorded in "Noninterest income" in the Consolidated Statements of Income. The impact to noninterest income for the years ended December 31, 2023, 2022 and 2021was a decrease of $0.4 million, $0.1 million and $0.5 million, respectively. Interest rate lock commitments and commitments to deliver loans to investors are considered derivatives. The market value of interest rate lock commitments and best efforts contracts are not readily ascertainable with precision because they are not actively traded in stand-alone markets. We determine the fair value of rate lock commitments and delivery contracts by measuring the fair value of the underlying asset, which is impacted by current interest rates and taking into consideration the probability that the rate lock commitments will close or will be funded. At December 31, 2023, the underlying funded mortgage loan commitments had a carrying value of $7.1 million and a fair value of $8.1 million, while the underlying unfunded mortgage loan commitments had a notional amount of $38.2 million. At December 31, 2022, the underlying funded mortgage loan commitments had a carrying value of $4.3 million and a fair value of $4.0 million, while the underlying unfunded mortgage loan commitments had a notional amount of $12.0 million. In addition, based on customer activity, a small amount of interest income on loans may be exposed to changes in foreign exchange rates. Several commercial borrowers have a portion of their operations outside of the United States and borrow funds on a short-term basis to fund those operations. In order to reduce the risk related to the translation of foreign denominated transactions into U.S. dollars, the Company may enter into foreign exchange forward contracts. These contracts relate principally to the Euro and the Canadian dollar. The contracts are recorded at fair value with changes in fair value recorded in "Other operating expenses" in the Consolidated Statements of Income. There were no foreign exchange forward contracts outstanding at December 31, 2023 and 2022. There was no impact on noninterest expense for the year ended December 31, 2023 and the impact for the years ended December 31, 2022 and 2021 totaled $5 thousand and $11 thousand, respectively.

These obligations have contractual maturities ranging from less than one year to approximately 30 years with lower anticipated lives to maturity due to prepayments. All mortgage backed securities contain a certain amount of risk related to the uncertainty of prepayments of the underlying mortgages. Interest rate changes have a direct impact upon prepayment speeds; therefore, First Commonwealth uses computer simulation models to test the average life and yield volatility of all mortgage backed securities under various interest rate scenarios to monitor the potential impact on earnings and interest rate risk positions. Expected maturities will differ from contractual maturities because issuers may have the right to call or repay obligations with or without call or prepayment penalties. Other fixed income securities within the portfolio also contain prepayment risk.

Other Investments As a member of the FHLB, First Commonwealth is required to purchase and hold stock in the FHLB to satisfy membership and borrowing requirements. The level of stock required to be held is dependent on the amount of First Commonwealth's mortgage related assets and outstanding borrowings with the FHLB. This stock is restricted in that it can only be sold to the FHLB or to another member institution, and all sales of FHLB stock must be at par. As a result of these restrictions, FHLB stock is unlike other investment securities insofar as there is no trading market for FHLB stock and the transfer price is determined by FHLB membership rules and not by market participants. As of December 31, 2023 and 2022, our FHLB stock totaled $44.7 million and $25.2 million, respectively and is included in “Other investments” on the Consolidated Statements of Financial Condition. FHLB stock is held as a long-term investment and its value is determined based on the ultimate recoverability of the par value. First Commonwealth evaluates impairment quarterly and has concluded that the par value of its investment in FHLB stock will be recovered. Accordingly, no impairment charge was recorded on these securities for the year ended December 31, 2023. At December 31, 2023 and 2022, Other Investments consisted of $6.2 million and $1.2 million, respectively, of securities that include bankers bank membership stock and investments in community development organizations. These securities do not have a readily determinable fair value and are carried at cost. For the years ended December 31, 2023 and 2022, there were no gains or losses recognized through earnings on equity securities. On a quarterly basis, management evaluates equity securities by reviewing research reports, analysts’ recommendations, credit rating changes, news stories, annual reports, regulatory filings, impact of interest rate changes and other relevant information. Impairment of Investment Securities We review our investment portfolio on a quarterly basis for indications of impairment. For available for sale securities the review includes analyzing the financial condition and near-term prospects of the issuer, including any specific events which may influence the operations of the issuer and whether we are more likely than not to sell the security. We evaluate whether we are more likely than not to sell debt securities based upon our investment strategy for the particular type of security and our cash flow needs, liquidity position, capital adequacy, tax position and interest rate risk position. Held-to-maturity securities are evaluated for impairment on a quarterly basis using historical probability of default and loss given default information specific to the investment category. If this evaluation determines that credit losses exist, an allowance for credit loss is recorded and included in earnings as a component of credit loss expense. First Commonwealth utilizes the specific identification method to determine the net gain or loss on debt securities and the average cost method to determine the net gain or loss on equity securities. The following table presents the gross unrealized losses and estimated fair values at December 31, 2023 for available for sale securities for which an allowance for credit losses has not been recorded and held to maturity securities by investment category and time frame for which the securities have been in a continuous unrealized loss position: Less Than 12 Months 12 Months or More Total Estimated Gross Estimated Gross Estimated Gross (dollars in thousands) Obligations of U.S. Government Agencies: Mortgage-Backed Securities – Residential $ — $ — $ 3,395 $ (322) $ 3,395 $ (322) Mortgage-Backed Securities – Commercial — — 300,642 (66,956) 300,642 (66,956) Obligations of U.S. Government-Sponsored Enterprises: Mortgage-Backed Securities – Residential 1,124 (3) 643,735 (115,367) 644,859 (115,370) Mortgage-Backed Securities – Commercial — — 2,160 (30) 2,160 (30) Other Government-Sponsored Enterprises — — 19,280 (4,263) 19,280 (4,263) Obligations of States and Political Subdivisions 2,641 (62) 26,887 (3,377) 29,528 (3,439) Debt Securities Issued by Foreign Governments 199 (1) 765 (35) 964 (36) Corporate Securities 11,416 (45) 21,426 (3,574) 32,842 (3,619) Total Securities $ 15,380 $ (111) $ 1,018,290 $ (193,924) $ 1,033,670 $ (194,035) At December 31, 2023, fixed income securities issued by U.S. Government Agencies and U.S. Government-sponsored enterprises comprised 96% of total unrealized losses. All unrealized losses are a result of changes in market interest rates. At December 31, 2023, there were 207 debt securities in an unrealized loss position. There were no equity securities in an unrealized loss position at December 31, 2023. The following table presents the gross unrealized losses and estimated fair value at December 31, 2022 for both available for sale and held to maturity securities by investment category and time frame for which the securities had been in a continuous unrealized loss position: Less Than 12 Months 12 Months or More Total Estimated Gross Estimated Gross Estimated Gross (dollars in thousands) Obligations of U.S. Government Agencies: Mortgage-Backed Securities – Residential $ 3,734 $ (405) $ — $ — $ 3,734 $ (405) Mortgage-Backed Securities – Commercial 92,208 (12,364) 240,241 (54,722) 332,449 (67,086) Obligations of U.S. Government-Sponsored Enterprises: Mortgage-Backed Securities – Residential 239,760 (21,543) 482,195 (110,306) 721,955 (131,849) Mortgage-Backed Securities – Commercial 4,666 (129) — — 4,666 (129) Other Government-Sponsored Enterprises — — 18,603 (4,619) 18,603 (4,619) Obligations of States and Political Subdivisions 21,234 (1,979) 9,230 (2,181) 30,464 (4,160) Debt Securities Issued by Foreign Governments 587 (13) 373 (27) 960 (40) Corporate Securities 14,406 (590) 12,632 (2,395) 27,038 (2,985) Total Securities $ 376,595 $ (37,023) $ 763,274 $ (174,250) $ 1,139,869 $ (211,273) As of December 31, 2023, our corporate securities had an amortized cost and estimated fair value of $51.9 million and $48.4 million, respectively. At December 31, 2022, these securities had an amortized cost of $32.0 million and estimated fair value of $29.2 million. When unrealized losses exist, management reviews each of the issuer’s asset quality, earnings trend and capital position, to determine whether the unrealized loss position is a result of credit losses. All interest payments on the corporate securities are being made as contractually required.

When calculating the allowance for credit losses these categories are classified into fourteen portfolio segments. The composition of loans by portfolio segment includes; Commercial, financial, agricultural and other Time & Demand - Consists primarily of commercial and industrial loans. This category consists of loans that are typically cash flow dependent and therefore have different risk and loss characteristics than other commercial loans. Loans in this category include revolving and term structures with fixed and variable interest rates. The primary macroeconomic drivers for estimating credit losses for this category include forecasts of national unemployment and economic conditions measured by GDP. At December 31, 2023 and 2022, this category includes $0.2 million and $4.3 million, respectively, in Paycheck Protection Program ("PPP") loans for small businesses. Because PPP loans are fully guaranteed by the SBA, there is no allowance for credit losses recognized for these loans. Commercial Credit Cards - Consists of unsecured credit cards for commercial customers. These commercial credit cards have separate characteristics outside of normal commercial non-real estate loans, as they tend to have shorter overall duration. The primary macroeconomic drivers for estimating credit losses for this category include forecasts of national unemployment and economic conditions measured by GDP. Equipment Finance - Consists of loans and leases to finance the purchase of equipment for commercial customers. The risk and loss characteristics are unique for this group due to the type of collateral. The primary macroeconomic drivers for estimating credit losses for this category include forecasts of national unemployment and economic conditions measured by GDP. Time & Demand Other - Consists primarily of loans to state and political subdivisions and other commercial loans that have different characteristics than loans in the Time and Demand category. The primary macroeconomic drivers for estimating credit losses for this category include forecasts of household debt to income and economic conditions measured by GDP. Real estate construction Construction Other - Consists of construction loans to commercial builders and developers and are secured by the properties under development. Construction Residential - Consists of loans to finance the construction of residential properties during the construction period. Borrowers are typically individuals who will occupy the completed single family property. The risk and loss characteristics of these two construction categories are different than other real estate secured categories due to the collateral being at various stages of completion. The nature of the project and type of borrower of the two construction categories provides for unique risk and loss characteristics for each category. The primary macroeconomic drivers for estimating credit losses for construction loans include forecasts of national unemployment and measures of completed construction projects. Residential real estate Residential first lien - Consists of loans with collateral of 1-4 family residencies with a senior lien position. The risk and loss characteristics are unique for this group because the collateral for these loans are the borrower’s primary residence. The primary macroeconomic drivers for estimating credit losses for this category include forecasts of national unemployment and residential property values. Residential Junior Lien/Home Equity - Consists of loans with collateral of 1-4 family residencies with an open end line of credit or junior lien position. The junior lien position for the majority of these loans provides a higher risk of loss than other residential real estate loans. The primary macroeconomic drivers for estimating credit losses for this category include forecasts of national unemployment and residential property values. Commercial real estate Multifamily - Consists of loans secured by commercial multifamily properties. Real estate related to rentals to consumers provide unique risk and loss characteristics. The primary macroeconomic drivers for estimating credit losses for this category include forecasts of commercial real estate values and national unemployment. Non-owner Occupied - Consists of loans secured by commercial real estate non-owner occupied and provides different loss characteristics than other real estate categories. The primary macroeconomic drivers for estimating credit losses for this category include forecasts of national unemployment and economic conditions measured by GDP. Owner Occupied - Consists of loans secured by commercial real estate owner occupied properties. The risk and loss characteristics of this category were considered different than other real estate categories because it is owner occupied and would impact the ability to conduct business. The primary macroeconomic drivers for estimating credit losses for this category include forecasts of national unemployment and economic conditions measured by GDP. Loans to individuals Automobile and recreational vehicles - Consists of both direct and indirect loans with automobiles and recreational vehicles held as collateral. The primary macroeconomic drivers for estimating credit losses for this category include forecasts of consumer sentiment and automobile retention value. Consumer Credit Cards – Consists of unsecured consumer credit cards The primary macroeconomic drivers for estimating credit losses for this category include forecasts of consumer sentiment and economic conditions measured by GDP. Other Consumer - Consists of lines of credit, student loans and other consumer loans, not secured by real estate or autos. The primary macroeconomic drivers for estimating credit losses for this category include forecasts of consumer sentiment and retail sales. The allowance for credit losses is calculated by pooling loans of similar credit risk characteristics and applying a discounted cash flow methodology after incorporating probability of default and loss given default estimates. Probability of default represents an estimate of the likelihood of default and loss given default measures the expected loss upon default. Inputs impacting the expected losses include a forecast of macroeconomic factors, using a weighted forecast from a nationally recognized firm. Our model incorporates a one-year forecast of macroeconomic factors, after which the factors revert back to the historical mean over a one-year period. The most significant macroeconomic factor used in estimating credit losses is the national unemployment rate. The forecasted value for national unemployment at the beginning of the forecast period was 3.79% and during the one-year forecast period it was projected to average 4.55%, with a peak of 4.82%. Credit Quality Information As part of the on-going monitoring of credit quality within the loan portfolio, the following credit worthiness categories are used in grading our commercial loans: Pass Acceptable levels of risk exist in the relationship. Includes all loans not classified as OAEM, substandard or doubtful. Other Assets Especially Mentioned (OAEM) Potential weaknesses that deserve management’s close attention. The potential weaknesses may result in deterioration of the repayment prospects or weaken the Bank’s credit position at some future date. The credit risk may be relatively minor, yet constitute an undesirable risk in light of the circumstances surrounding the specific credit. No loss of principal or interest is expected. Substandard Well-defined weakness or a weakness that jeopardizes the repayment of the debt. A loan may be classified as substandard as a result of deterioration of the borrower’s financial condition and repayment capacity. Loans for which repayment plans have not been met or collateral equity margins do not protect the Company may also be classified as substandard. Doubtful Loans with the characteristics of substandard loans with the added characteristic that collection or liquidation in full, on the basis of presently existing facts and conditions, is highly improbable. The Company’s internal creditworthiness grading system provides a measurement of credit risk based primarily on an evaluation of the borrower’s cash flow and collateral. Category ratings are reviewed each quarter, at which time management analyzes the results, as well as other external statistics and factors related to loan performance.

can potentially represent significant risk to our earnings, capital and liquidity. First Commonwealth devotes substantial resources to managing this risk primarily through our credit administration department that develops and administers policies and procedures for underwriting, maintaining, monitoring and collecting loans. Credit administration is independent of lending departments and oversight is provided by the Credit Committee of the First Commonwealth Board of Directors. Total gross charge-offs for the years ended December 31, 2023 and 2022 were $33.3 million and $9.8 million, respectively. Age Analysis of Past Due Loans by Segment The following tables delineate the aging analysis of the recorded investments in past due loans as of December 31. Also included in these tables are loans that are 90 days or more past due and still accruing because they are well-secured and in the process of collection. 2023 30 - 59 60 - 89 90 days Nonaccrual Total past Current Total (dollars in thousands) Commercial, financial, agricultural and other $ 1,206 $ 745 $ 4,187 $ 10,060 $ 16,198 $ 1,527,151 $ 1,543,349 Time and demand 565 691 4,187 9,218 14,661 1,172,639 1,187,300 Commercial credit cards 7 54 — — 61 12,845 12,906 Equipment finance 600 — — 842 1,442 231,502 232,944 Time and demand other 34 — — — 34 110,165 110,199 Real estate construction — — — 3,288 3,288 594,447 597,735 Construction other — — — 3,288 3,288 538,345 541,633 Construction residential — — — — — 56,102 56,102 Residential real estate 6,982 1,535 1,062 8,573 18,152 2,398,724 2,416,876 Residential first lien 4,130 940 171 4,443 9,684 1,729,423 1,739,107 Residential junior lien/home equity 2,852 595 891 4,130 8,468 669,301 677,769 Commercial real estate 4,157 — 3,509 17,385 25,051 3,028,101 3,053,152 Multifamily — — — 55 55 551,087 551,142 Non-owner occupied 2,303 — 3,509 14,282 20,094 1,752,691 1,772,785 Owner occupied 1,854 — — 3,048 4,902 724,323 729,225 Loans to individuals 4,613 878 678 166 6,335 1,351,314 1,357,649 Automobile and recreational vehicles 4,115 612 151 164 5,042 1,272,927 1,277,969 Consumer credit cards 39 71 — — 110 10,181 10,291 Consumer other 459 195 527 2 1,183 68,206 69,389 Total $ 16,958 $ 3,158 $ 9,436 $ 39,472 $ 69,024 $ 8,899,737 $ 8,968,761 2022 30 - 59 60 - 89 90 days Nonaccrual Total past Current Total (dollars in thousands) Commercial, financial, agricultural and other $ 1,233 $ 279 $ 355 $ 2,374 $ 4,241 $ 1,207,465 $ 1,211,706 Time and demand 1,121 270 352 2,374 4,117 1,019,707 1,023,824 Commercial credit cards 27 9 — — 36 13,884 13,920 Equipment finance — — — — — 79,674 79,674 Time and demand other 85 — 3 — 88 94,200 94,288 Real estate construction 502 — — — 502 512,599 513,101 Construction other — — — — — 395,439 395,439 Construction residential 502 — — — 502 117,160 117,662 Residential real estate 3,023 1,178 811 5,683 10,695 2,183,974 2,194,669 Residential first lien 1,547 771 214 3,369 5,901 1,541,291 1,547,192 Residential junior lien/home equity 1,476 407 597 2,314 4,794 642,683 647,477 Commercial real estate 7,870 25 93 20,539 28,527 2,396,485 2,425,012 Multifamily 202 — — — 202 430,949 431,151 Non-owner occupied 7,547 — 92 19,575 27,214 1,483,133 1,510,347 Owner occupied 121 25 1 964 1,111 482,403 483,514 Loans to individuals 3,268 571 732 449 5,020 1,292,635 1,297,655 Automobile and recreational vehicles 2,694 368 295 361 3,718 1,206,733 1,210,451 Consumer credit cards 53 29 5 — 87 10,570 10,657 Consumer other 521 174 432 88 1,215 75,332 76,547 Total $ 15,896 $ 2,053 $ 1,991 $ 29,045 $ 48,985 $ 7,593,158 $ 7,642,143 Nonaccrual Loans The previous tables summarize nonaccrual loans by loan segment. The Company generally places loans on nonaccrual status when the full and timely collection of interest or principal becomes uncertain, when part of the principal balance has been charged off and no restructuring has occurred, or the loans reach a certain number of days past due. Generally, loans 90 days or more past due are placed on nonaccrual status, except for consumer loans which are placed in nonaccrual status at 150 days past due. When a loan is placed on nonaccrual, the accrued unpaid interest receivable is reversed against interest income and all future payments received are applied as a reduction to the loan principal. Generally, the loan is returned to accrual status when (a) all delinquent interest and principal become current under the terms of the loan agreement or (b) the loan is both well-secured and in the process of collection and collectability is no longer in doubt. Nonperforming Loans Management considers loans to be nonperforming when, based on current information and events, it is determined that the Company will not be able to collect all amounts due according to the loan contract, including scheduled interest payments. When management identifies a loan as nonperforming, the credit loss is measured based on the present value of expected future cash flows, discounted at the loan’s effective interest rate, except when the sole source or repayment for the loan is the operation or liquidation of collateral. When the loan is collateral dependent, the appraised value less estimated cost to sell is utilized. If management determines the value of the loan is less than the recorded investment in the loan, a credit loss is recognized through an allowance estimate or a charge-off to the allowance for credit losses. When the ultimate collectability of the total principal of a nonperforming loan is in doubt and the loan is on nonaccrual status, all payments are applied to principal, under the cost recovery method. When the ultimate collectability of the total principal of a nonperforming loan is not in doubt and the loan is on nonaccrual status, contractual interest is credited to interest income when received under the cash basis method. There were no nonperforming loans held for sale at December 31, 2023 and 2022. There were no gains on nonperforming loans held for sale during both of the years ended December 31, 2023 and 2022. There was $0.4 million in gains on sale of nonperforming loans recognized during the year ended December 31, 2021. The following tables include the recorded investment and unpaid principal balance for nonperforming loans with the associated allowance amount, if applicable, as of December 31, 2023 and 2022. Also presented are the average recorded investment in nonperforming loans and the related amount of interest recognized while the loan was considered nonperforming. Average balances are calculated based on month-end balances of the loans for the period reported and are included in the table below based on its period end allowance position. The increase in nonperforming loans is primarily a result of $14.5 million in loans acquired from Centric, offset by the removal of $6.4 million in accruing TDR's. The TDR's were eliminated as a result of our adoption of ASU 2022-02. 2023 Recorded Unpaid Related Average Interest (dollars in thousands) With no related specific allowance recorded: Commercial, financial, agricultural and other $ 4,369 $ 18,014 $ 7,895 $ 143 Time and demand 3,527 17,172 7,569 143 Equipment finance 842 842 326 — Time and demand other — — — — Real estate construction 3,288 3,288 1,096 — Construction other 3,288 3,288 1,096 — Construction residential — — — — Residential real estate 7,042 8,763 6,440 136 Residential first lien 4,161 5,151 3,760 129 Residential junior lien/home equity 2,881 3,612 2,680 7 Commercial real estate 12,402 18,219 20,715 260 Multifamily 55 58 37 — Non-owner occupied 10,971 17,092 18,454 122 Owner occupied 1,376 1,069 2,224 138 Loans to individuals 166 259 365 7 Automobile and recreational vehicles 164 257 299 7 Consumer other 2 2 66 — Subtotal 27,267 48,543 36,511 546 With a specific allowance recorded: Commercial, financial, agricultural and other 5,691 6,787 $ 4,044 6,574 (16) Time and demand 5,691 6,787 4,044 6,574 (16) Equipment finance — — — — — Time and demand other — — — — — Real estate construction — — — — — Construction other — — — — — Construction residential — — — — — Residential real estate 1,531 1,697 118 1,183 — Residential first lien 282 279 39 47 — Residential junior lien/home equity 1,249 1,418 79 1,136 — Commercial real estate 4,983 5,294 387 655 — Multifamily — — — — — Non-owner occupied 3,311 3,550 174 397 — Owner occupied 1,672 1,744 213 258 — Loans to individuals — — — — — Automobile and recreational vehicles — — — — — Consumer other — — — — — Subtotal 12,205 13,778 4,549 8,412 (16) Total $ 39,472 $ 62,321 $ 4,549 $ 44,923 $ 530 2022 Recorded Unpaid Related Average Interest (dollars in thousands) With no related specific allowance recorded: Commercial, financial, agricultural and other $ 3,141 $ 9,555 $ 3,751 $ 157 Time and demand 3,141 9,555 3,751 157 Equipment finance — — — — Time and demand other — — — — Real estate construction — — — — Construction other — — — — Construction residential — — — — Residential real estate 9,145 11,010 9,040 241 Residential first lien 5,754 6,848 5,280 172 Residential junior lien/home equity 3,391 4,162 3,760 69 Commercial real estate 21,505 24,119 22,983 172 Multifamily — — 172 43 Non-owner occupied 20,155 22,565 21,304 104 Owner occupied 1,350 1,554 1,507 25 Loans to individuals 528 563 455 16 Automobile and recreational vehicles 440 475 378 16 Consumer other 88 88 77 — Subtotal 34,319 45,247 36,229 586 With a specific allowance recorded: Commercial, financial, agricultural and other 1,168 1,186 $ 711 261 8 Time and demand 1,168 1,186 711 261 8 Equipment finance — — — — — Time and demand other — — — — — Real estate construction — — — — — Construction other — — — — — Construction residential — — — — — Residential real estate — — — — — Residential first lien — — — — — Residential junior lien/home equity — — — — — Commercial real estate — — — — — Multifamily — — — — — Non-owner occupied — — — — — Owner occupied — — — — — Loans to individuals — — — — — Automobile and recreational vehicles — — — — — Consumer other — — — — — Subtotal 1,168 1,186 711 261 8 Total $ 35,487 $ 46,433 $ 711 $ 36,490 $ 594 2021 Average Interest (dollars in thousands) With no related specific allowance recorded: Commercial, financial, agricultural and other $ 9,240 $ 389 Time and demand 9,240 389 Real estate construction 53 — Residential real estate 10,315 375 Residential first lien 5,674 279 Residential junior lien/home equity 4,641 96 Commercial real estate 26,235 119 Multifamily 1,223 — Non-owner occupied 22,668 28 Owner occupied 2,344 91 Loans to individuals 479 15 Automobile and recreational vehicles 425 15 Consumer other 54 — Subtotal 46,322 898 With a specific allowance recorded: Commercial, financial, agricultural and other 84 — Time and demand 84 — Real estate construction — — Residential real estate — — Residential first lien — — Residential junior lien/home equity — — Commercial real estate 665 — Multifamily 444 — Non-owner occupied — — Owner occupied 221 — Loans to individuals — — Automobile and recreational vehicles — — Consumer other — — Subtotal 749 — Total $ 47,071 $ 898 Unfunded commitments related to nonperforming loans were $0.1 million and $0.2 million at December 31, 2023 and 2022, respectively. After consideration of the requirements to draw and available collateral related to these commitments, it was determined that no reserve was required for these commitments at December 31, 2023 or 2022. Loan Modifications Made to Borrowers Experiencing Financial Difficulty The Company adopted ASU 2022-02 on January 1, 2023 on a prospective basis. Disclosures for years prior to adoption continue to reflect TDR's as nonperforming loans and include TDR disclosures required under the previous guidance. Upon adoption of this guidance, the Company no longer establishes a specific reserve for modifications to borrowers experiencing financial difficulty. Instead, these modifications are included in their respective loan segment and an allowance is determined by a loss given default and probability of default methodology. Modifications to borrowers experiencing financial difficulty may include interest rate reductions, principal forgiveness, other-than-insignificant payment delay, term extensions or any combination thereof.

Commitments and Letters of Cred

Commitments and Contingencies Disclosure [Abstract]
Commitments and Letters of Credit	Commitments and Letters of Credit First Commonwealth is a party to financial instruments with off-balance sheet risk in the normal course of business to meet the financial needs of its customers. These financial instruments include commitments to extend credit, standby letters of credit and commercial letters of credit. Those instruments involve, to varying degrees, elements of credit and interest rate risk in excess of the amount recognized in the Consolidated Statements of Financial Condition. First Commonwealth’s exposure to credit loss in the event of nonperformance by the other party of the financial instrument for commitments to extend credit, standby letters of credit and commercial letters of credit is represented by the contract or notional amount of those instruments. First Commonwealth uses the same credit policies for underwriting all loans, including these commitments and conditional obligations. As of December 31, 2023 and 2022, First Commonwealth did not own or trade other financial instruments with significant off-balance sheet risk including derivatives such as futures, forwards, option contracts and the like, although such instruments may be appropriate to use in the future to manage interest rate risk. See Note 7, “Derivatives,” for a description of interest rate derivatives entered into by First Commonwealth. Standby letters of credit and commercial letters of credit are conditional commitments issued by First Commonwealth to guarantee the performance of a customer to a third party. The contract or notional amount of these instruments reflects the maximum amount of future payments that First Commonwealth could be required to pay under the guarantees if there were a total default by the guaranteed parties, without consideration for possible recoveries under recourse provisions or from collateral held or pledged. In addition, many of these commitments are expected to expire without being drawn upon; therefore, the total commitment amounts do not necessarily represent future cash requirements. The following table identifies the notional amount of those instruments at December 31: 2023 2022 (dollars in thousands) Financial instruments whose contract amounts represent credit risk: Commitments to extend credit $ 2,517,905 $ 2,356,539 Financial standby letters of credit 14,300 18,417 Performance standby letters of credit 17,194 12,853 Commercial letters of credit 555 573 Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Since many of the commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. First Commonwealth evaluates each customer’s creditworthiness on a case-by-case basis. The amount of collateral obtained, if deemed necessary by First Commonwealth upon extension of credit, is based on management’s credit evaluation of the counterparty. Collateral that is held varies but may include accounts receivable, inventory, property, plant and equipment, and residential and income-producing commercial properties. The notional amounts outstanding at December 31, 2023 include amounts issued in 2023 of $0.3 million in financial standby letters of credit and $1.3 million in performance standby letters of credit. There were no commercial letters of credit issued during 2023. A liability of $0.1 million has been recorded as of December 31, 2023 and 2022, which represents the estimated fair value of letters of credit issued. The fair value of letters of credit is estimated based on the unrecognized portion of fees received at the time the commitment was issued. Unused commitments and letters of credit provide exposure to future credit loss in the event of nonperformance by the borrower or guaranteed parties. Management’s evaluation of the credit risk in these commitments resulted in the recording of a liability of $7.3 million and $10.0 million as of December 31, 2023 and 2022, respectively. This liability is reflected in “ Other liabilities ” in the Consolidated Statements of Financial Condition. The credit risk evaluation incorporates the expected loss percentage calculated for comparable loan categories as part of the allowance for credit losses for loans.

Amortization of lease right-of-use assets totaled $3.6 million in 2023, $3.4 million in 2022 and $1.4 million in 2021. Lease Commitments First Commonwealth has elected to apply certain practical expedients under ASU 2016-02 "Leases" (Topic 842), including (i) to not apply the requirements in the new standard to short-term leases (ii) to not reassess the lease classification for any expired or existing lease (iii) to account for lease and non-lease components separately (iv) to not reassess initial direct costs for any existing leases. The impact of this standard primarily relates to operating leases of certain real estate properties, primarily certain branch and ATM locations and office space. First Commonwealth has no material leasing arrangements for which it is the lessor of property or equipment. The following table represents the lease costs and other lease information for the years ended December 31. 2023 2022 (dollars in thousands) Balance sheet: Operating lease asset classified as premises and equipment $ 45,005 $ 40,747 Operating lease liability classified as other liabilities 49,327 45,149 Income statement: Operating lease cost classified as occupancy and equipment expense $ 6,089 $ 4,990 Weighted average lease term, in years 13.19 13.95 Weighted average discount rate 3.54 % 3.29 % Operating cash flows $ 6,169 $ 4,838 In the above table, the increase in the ROU asset and lease liability at December 31, 2023 compared to December 21, 2022, is primarily a result of leases assumed as part of the Centric acquisition. The ROU assets and lease liabilities are impacted by the length of the lease term and the discount rate used to present value the minimum lease payments. First Commonwealth's lease agreements often include one or more options to renew at the Company's discretion. If we consider the renewal option to be reasonably certain, we include the extended term in the calculation of the ROU asset and lease liability. First Commonwealth uses incremental borrowing rates when calculating the lease liability because the rate implicit in the lease is not readily determinable. The incremental borrowing rate used by First Commonwealth is an amortizing loan rate obtained from the FHLB. This rate is consistent with a collateralized borrowing rate and is available for terms similar to the lease payment schedules. The following table reconciles future minimum lease payments due under non-cancelable operating leases (those amounts subject to recognition) to the lease liability a s of December 31, 2023 (dollars in thousands): For the twelve months ended December 31, 2024 $ 5,845 2025 5,621 2026 5,150 2027 4,884 2028 4,695 Thereafter 36,749 Total future minimum lease payments 62,944 Less remaining imputed interest 13,617 Operating lease liability $ 49,327 Rent expense, net of rental income, for all operating leases totaled $5.9 million in 2023, $4.7 million in 2022 and $4.5 million in 2021

Goodwill and Other Amortizing I

Goodwill and Other Amortizing Intangible Assets	12 Months Ended

Goodwill Disclosure [Abstract]
Goodwill and Other Amortizing Intangible Assets	Goodwill and Other Intangible Assets FASB ASC Topic 350-20, “Intangibles—Goodwill and Other" ("Topic 350"), requires an annual valuation of the fair value of a reporting unit that has goodwill and a comparison of the fair value to the book value of equity to determine whether the goodwill has been impaired. Goodwill is also required to be tested on an interim basis if an event or circumstance indicates that it is more likely than not that an impairment loss has been incurred. When circumstances indicate that it is more likely than not that fair value is less than carrying value, a triggering event has occurred and a quantitative impairment test would be performed. We consider First Commonwealth to be one reporting unit. The carrying amount of goodwill as of December 31, 2023 and 2022 was $363.7 million and $303.3 million, respectively. The $60.4 million increase in goodwill during the year ended December 31, 2023 is the result of the Centric acquisition. No impairment charges on goodwill or other intangible assets were incurred in 2023, 2022 or 2021. We test goodwill for impairment as of November 30th each year and again at any quarter-end if any material events occur during a quarter that may affect goodwill. At November 30, 2023, the Company completed its annual goodwill impairment analysis and determined that it was more likely than not that the fair value of the Company was in excess of its carrying value, therefore goodwill was not considered impaired. As of December 31, 2023, no indicators of impairment were identified; however, changing economic conditions that may adversely affect our performance, the fair value of our assets and liabilities, or our stock price could result in impairment, which could adversely affect earnings in future periods. Management will continue to monitor events that could impact this conclusion in the future. Topic 350 also requires that an acquired intangible asset be separately recognized if the benefit of the intangible asset is obtained through contractual or other legal rights, or if the asset can be sold, transferred, licensed, rented or exchanged, regardless of the acquirer’s intent to do so. The following table summarizes other intangible assets: Gross Accumulated Net (dollars in thousands) December 31, 2023 Customer deposit intangibles $ 39,244 $ (20,747) $ 18,497 Customer list intangible 2,283 (2,049) 234 Total other intangible assets $ 41,527 $ (22,796) $ 18,731 December 31, 2022 Customer deposit intangibles $ 22,573 $ (16,750) $ 5,823 Customer list intangible 2,283 (1,921) 362 Total other intangible assets $ 24,856 $ (18,671) $ 6,185 Core deposits are amortized over their expected lives using the present value of the benefit of the core deposits and straight-line methods of amortization. The $12.7 million increase in core deposit intangibles for the year ended December 31, 2023 is a result of the Centric acquisition. The core deposits have a remaining amortization period of 6.5 years and a weighted average amortization period of approximately 6.1 years. The customer list intangible represents the estimated value of the customer base for an insurance agency acquired in 2014 and the wealth management business acquired as part of the DCB acquisition in 2017. These amounts are amortized over their expected lives using expected cash flows based on retention of the customer base. The customer list intangible has a remaining amortization period of 5.7 years and a weighted average amortization period of 4.0 years. First Commonwealth recognized amortization expense on other intangible assets of $4.1 million, $2.5 million, and $2.9 million for the years ended December 31, 2023, 2022 and 2021, respectively. In addition to customer deposit intangibles and customer list intangibles, First Commonwealth has servicing rights on mortgage loans as well as certain commercial loans totaling $4.1 million and $3.0 million as of December 31, 2023 and 2022, respectively. These servicing rights relate to loans sold to third parties on which the Company retains servicing responsibilities. The Company recognized amortization expense on these servicing assets of $0.9 million, $0.7 million and $0.6 million for the years ended December 31, 2023, 2022 and 2021, respectively. The following presents the estimated amortization expense of core deposit and customer list intangibles: Core Deposit Intangibles Customer List Intangible Total (dollars in thousands) 2024 $ 3,775 $ 97 $ 3,872 2025 3,364 69 3,433 2026 2,955 42 2,997 2027 2,565 15 2,580 2028 2,428 7 2,435 Thereafter 3,410 4 3,414 Total $ 18,497 $ 234 $ 18,731

The rate remains fixed at 4.50% until March 29, 2026, then adjusts quarterly to Prime + 1.00%. The Bank may redeem the notes, beginning with the interest payment due on March 29, 2026, in whole or in part at a redemption price equal to 100% of the principal amount of the subordinated notes, plus accrued and unpaid interest to the date of redemption. A fair value premium of $0.6 million was recognized in connection with the acquisition. On May 21, 2018, First Commonwealth Bank issued ten-year subordinated notes with an aggregate principal amount of $50.0 million. Interest is paid quarterly at a rate of three-month CME Term SOFR + 0.26161% + 1.845%. The Bank may redeem the notes, in whole or in part, at a redemption price equal to 100% of the principal amount of the subordinated notes, plus accrued and unpaid interest to the date of redemption. Deferred issuance costs of $0.9 million are being amortized on a straight-line basis over the term of the notes. On May 21, 2018, First Commonwealth Bank also issued fifteen-year subordinated notes with an aggregate principal amount of $50.0 million and a fixed-to-floating rate of 5.50%. The rate remains fixed until June 1, 2028, then adjusts on a quarterly basis to three-month CME Term SOFR + 0.26161% + 2.37%. The Bank may redeem the notes, beginning with the interest payment due on June 1, 2028, in whole or in part, at a redemption price equal to 100% of the principal amount of the subordinated notes, plus accrued and unpaid interest to the date of redemption. Deferred issuance costs of $1.1 million are being amortized on a straight-line basis over the term of the notes. First Commonwealth currently has two trusts, First Commonwealth Capital Trust II and First Commonwealth Capital Trust III, of which 100% of the common equity is owned by First Commonwealth. The trusts were formed for the purpose of issuing company obligated mandatorily redeemable capital securities to third-party investors and investing the proceeds from the sale of the capital securities solely in junior subordinated debt securities (“subordinated debentures”) of First Commonwealth. The subordinated debentures held by each trust are the sole assets of the trust. Interest on the debentures issued to First Commonwealth Capital Trust III is paid quarterly at a floating rate of three-month CME Term SOFR + 0.26161% + 2.85% which is reset quarterly. Subject to regulatory approval, First Commonwealth may redeem the debentures, in whole or in part, at its option on any interest payment date at a redemption price equal to 100% of the principal amount of the debentures, plus accrued and unpaid interest to the date of the redemption. Deferred issuance costs of $0.6 million are being amortized on a straight-line basis over the term of the securities. Interest on the debentures issued to First Commonwealth Capital Trust II is paid quarterly at a floating rate of three-month CME Term SOFR + 0.26161% + 2.85%, which is reset quarterly. Subject to regulatory approval, First Commonwealth may redeem the debentures, in whole or in part, at its option at a redemption price equal to 100% of the principal amount of the debentures, plus accrued and unpaid interest to the date of the redemption. Deferred issuance costs of $0.5 million are being amortized on a straight-line basis over the term of the securities. In order to reduce its exposure to variability in expected future cash flows related to interest payments on First Commonwealth Capital Trust II and III, the Company entered into two interest rate swap contracts that are designated as cash flow hedges. These contracts fix the index based portion of the interest rate on Capital Trust II at 1.515% until August 15, 2024 and on Capital Trust III at 1.525% until August 15, 2026. Additional information related to these cash flow hedges can be found in Note 7- "Derivatives".

Fair Value Disclosures [Abstract]
Fair Values of Assets and Liabilities	Fair Values of Assets and Liabilities FASB ASC Topic 820 requires disclosures for non-financial assets and non-financial liabilities, except for items that are recognized or disclosed at fair value in the financial statements on a recurring basis (at least annually). All non-financial assets are included either as a separate line item on the Consolidated Statements of Financial Condition or in the “Other assets” category of the Consolidated Statements of Financial Condition. Currently, First Commonwealth does not have any non-financial liabilities to disclose. FASB ASC Topic 825, “Financial Instruments" ("Topic 825"), permits entities to irrevocably elect to measure select financial instruments and certain other items at fair value. The unrealized gains and losses are required to be included in earnings each reporting period for the items that fair value measurement is elected. First Commonwealth has elected not to measure any existing financial instruments at fair value under Topic 825; however, in the future we may elect to adopt this guidance for select financial instruments. In accordance with Topic 820, First Commonwealth groups financial assets and financial liabilities measured at fair value in three levels, based on the principal markets in which the assets and liabilities are transacted and the observability of the data points used to determine fair value. These levels are defined in Note 1, "Statement of Accounting Policies." Level 2 investment securities are valued by a recognized third party pricing service using observable inputs. The model used by the pricing service varies by asset class and incorporates available market, trade and bid information as well as cash flow information when applicable. Because many fixed-income investment securities do not trade on a daily basis, the model uses available information such as benchmark yield curves, benchmarking of like investment securities, sector groupings and matrix pricing. The model will also use processes such as an option-adjusted spread to assess the impact of interest rates and to develop prepayment estimates. Market inputs normally used in the pricing model include benchmark yields, reported trades, broker/dealer quotes, issuer spreads, two-sided markets, benchmark securities, bids, offers and reference data including market research publications. Management validates the market values provided by the third party service by having another source price 100% of the securities on a monthly basis, monthly monitoring of variances from prior period pricing and, on a monthly basis, evaluating pricing changes compared to expectations based on changes in the financial markets. Other Investments include FHLB stock whose estimated fair value is based on its par value. Additional information on FHLB stock is provided in Note 8, “Investment Securities.” Loans held for sale include residential mortgage loans originated for sale in the secondary mortgage market. The estimated fair value for these loans was determined on the basis of rates obtained in the respective secondary market. Loans held for sale could also include the Small Business Administration guaranteed portion of small business loans. The estimated fair value of these loans is based on the contract with the third party investor. When loans held for sale include other commercial loans, fair value is determined using an executed trade and market bid obtained from potential buyers. Interest rate derivatives are reported at an estimated fair value utilizing Level 2 inputs and are included in "Other assets" and "Other liabilities" in the Consolidated Statements of Financial Condition. These consist of interest rate swaps where there is no significant deterioration in the counterparties' (loan customers') credit risk since origination of the interest rate swap as well as interest rate caps, interest rate collars and risk participation agreements. First Commonwealth values its interest rate swap and cap positions using a yield curve by taking market prices/rates for an appropriate set of instruments. The set of instruments used to determine the U.S. Dollar yield curve includes SOFR rates from overnight to one year, Eurodollar futures contracts and SOFR swap rates from one year to thirty years. These yield curves determine the valuations of interest rate swaps. Interest rate derivatives are further described in Note 7, “Derivatives.” For purposes of potential valuation adjustments to our derivative positions, First Commonwealth evaluates the credit risk of its counterparties as well as our own credit risk. Accordingly, we have considered factors such as the likelihood of default, expected loss given default, net exposures and remaining contractual life, among other things, in determining if any estimated fair value adjustments related to credit risk are required. We review our counterparty exposure quarterly, and when necessary, appropriate adjustments are made to reflect the exposure. We also utilize this approach to estimate our own credit risk on derivative liability positions. In 2023 and 2022, we have not realized any losses due to a counterparty's inability to pay any net uncollateralized position. Interest rate derivatives also include interest rate forwards entered into to hedge residential mortgage loans held for sale and the related interest-rate lock commitments. This includes forward commitments to sell mortgage loans. The fair value of these derivative financial instruments are based on derivative market data inputs as of the valuation date and the underlying value of mortgage loans for rate lock commitments. In addition, at times the Company hedges foreign currency risk through the use of foreign exchange forward contracts. The fair value of foreign exchange forward contracts is based on the differential between the contract price and the market-based forward rate. The estimated fair value for other real estate owned included in Level 2 is determined by either an independent market based appraisal less estimated costs to sell or an executed sales agreement. The estimated fair value of the other investments included in Level 3 is based on carrying value as these securities do not have a readily determinable fair value. The estimated fair value of limited partnership investments included in Level 3 is based on par value. For interest rate derivatives included in Level 3, the fair value incorporates credit risk by considering such factors as likelihood of default and expected loss given default based on credit quality of the underlying counterparties (loan customers). In accordance with ASU 2011-4, the following table provides information related to quantitative inputs and assumptions used in Level 3 fair value measurements. Fair Value Valuation Technique Unobservable Inputs Range / (weighted December 31, 2023 Other Investments $ 6,182 Carrying Value N/A N/A Limited Partnership Investments 27,137 Par Value N/A N/A December 31, 2022 Other Investments 1,170 Carrying Value N/A N/A Nonperforming Loans 363 (a) Gas Reserve study Discount rate 10.00% Gas per MMBTU $3.00 - $3.00 (b) Oil per BBL/d $80.00 - $80.00 (b) Limited Partnership Investments 17,691 Par Value N/A N/A (a) the remainder of nonperforming loans valued using Level 3 inputs are not included in this disclosure as the values of those loans are based on bankruptcy agreement documentation. (b) unobservable inputs are defined as follows: MMBTU—one million British thermal units; BBL/d—barrels per day. The discount rate is the significant unobservable input used in the fair value measurement of nonperforming loans. Significant increases in this rate would result in a decrease in the estimated fair value of the loans, while a decrease in this rate would result in a higher fair value measurement. Other unobservable inputs in the fair value measurement of nonperforming loans relate to gas, oil and natural gas prices. Increases in these prices would result in an increase in the estimated fair value of the loans, while a decrease in these prices would result in a lower fair value measurement.

The fair value for nonperforming loans that are collateral based is determined by reviewing real property appraisals, equipment valuations, accounts receivable listings and other financial information. A discounted cash flow analysis is performed to determine fair value for nonperforming loans when an observable market price or a current appraisal is not available. For real estate secured loans, First Commonwealth’s loan policy requires updated appraisals be obtained at least every twelve months on all nonperforming loans with balances of $250 thousand and over. For real estate secured loans with balances under $250 thousand, we rely on broker price opinions. For non-real estate secured assets, the Company normally relies on third party valuations specific to the collateral type. The fair value of other real estate owned, determined by either an independent market based appraisal less estimated costs to sell or an executed sales agreement, is classified as Level 2. The fair value for other real estate owned determined using an internal valuation is classified as Level 3. Other real estate owned had a current carrying value of $0.4 million as of December 31, 2023 and consisted primarily of residential properties in Pennsylvania and Ohio. We review whether events and circumstances subsequent to a transfer to other real estate owned have occurred that indicate the balance of those assets may not be recoverable. If events and circumstances indicate further impairment, we will record a charge to the extent that the carrying value of the assets exceed their fair values, less estimated costs to sell, as determined by valuation techniques appropriate in the circumstances. Certain other assets and liabilities, including goodwill, core deposit intangibles and customer list intangibles are measured at fair value on a nonrecurring basis; that is, the instruments are not measured at fair value on an ongoing basis but are subject to fair value adjustments only in certain circumstances. Additional information related to this measurement is provided in Note 12 “Goodwill and Other Amortizing Intangible Assets.” There were no other assets or liabilities measured at fair value on a nonrecurring basis during 2023. FASB ASC Topic 825-10, “Transition Related to FSP FAS 107-1” and APB 28-1, “Interim Disclosures about Fair Value of Financial Instruments,” requires disclosure of the fair value of financial assets and financial liabilities, including those financial assets and financial liabilities that are not measured and reported at fair value on a recurring basis or nonrecurring basis. The methodologies for estimating the fair value of financial assets and financial liabilities that are measured at fair value on a recurring or nonrecurring basis are as discussed above. The methodologies for other financial assets and financial liabilities are provided below. Cash and due from banks and interest bearing bank deposits : The carrying amounts for cash and due from banks and interest-bearing bank deposits approximate the estimated fair values of such assets. Securities : Fair values for available for sale and held to maturity securities are based on quoted market prices, if available. If quoted market prices are not available, fair values are based on quoted market prices of comparable instruments. The carrying value of other investments, which includes FHLB stock, is considered a reasonable estimate of fair value. Loans held for sale : The estimated fair value of loans held for sale is based on market bids obtained from potential buyers. Loans: The fair values of all loans are estimated by discounting the estimated future cash flows using interest rates currently offered for loans with similar terms to borrowers of similar credit quality adjusted for past due and nonperforming loans. Off-balance sheet instruments : Many of First Commonwealth’s off-balance sheet instruments, primarily loan commitments and standby letters of credit, are expected to expire without being drawn upon; therefore, the commitment amounts do not necessarily represent future cash requirements. FASB ASC Topic 460, “Guarantees,” clarified that a guarantor is required to recognize, at the inception of a guarantee, a liability for the fair value of the obligation undertaken in issuing the guarantee. The carrying amount and estimated fair value for standby letters of credit was $0.1 million at both December 31, 2023 and 2022. See Note 10, “Commitments and Letters of Credit,” for additional information. Deposit liabilities : The estimated fair value of demand deposits, savings accounts and money market deposits is the amount payable on demand at the reporting date because of the customers' ability to withdraw funds immediately. The fair value of fixed rate time deposits are estimated by discounting the future cash flows using interest rates currently being offered and a schedule of aggregated expected maturities. Short-term borrowings : The fair values of borrowings from the FHLB were estimated based on the estimated incremental borrowing rate for similar types of borrowings. The carrying amounts of other short-term borrowings, such as federal funds purchased and securities sold under agreement to repurchase, were used to approximate fair value due to the short-term nature of the borrowings. Subordinated debt and long-term debt : The fair value is estimated by discounting the future cash flows using First Commonwealth’s estimate of the current market rate for similar types of borrowing arrangements.

Income Taxes	Income Taxes The income tax provision for the years ended December 31 is as follows: 2023 2022 2021 (dollars in thousands) Current tax provision: Federal $ 32,167 $ 33,545 $ 32,586 State 936 471 397 Total current tax provision 33,103 34,016 32,983 Deferred tax provision (benefit): Federal 7,488 (1,967) 1,501 State (99) (45) 76 Total deferred tax provision 7,389 (2,012) 1,577 Total tax provision $ 40,492 $ 32,004 $ 34,560 The statutory to effective tax rate reconciliation for the years ended December 31 is as follows: 2023 2022 2021 Amount % of Amount % of Amount % of (dollars in thousands) Tax at statutory rate $ 41,487 21 % $ 33,639 21 % $ 36,292 21 % Increase (decrease) resulting from: State income tax, net of federal benefit 725 — 361 — 326 — Income from bank owned life insurance (1,024) (1) (1,146) (1) (1,351) (1) Tax-exempt interest income, net (812) — (809) (1) (846) — Tax credits (804) — (341) — (127) — Other 920 — 300 1 266 — Total tax provision $ 40,492 20 % $ 32,004 20 % $ 34,560 20 % The total tax provision for financial reporting differs from the amount computed by applying the statutory federal income tax rate to income before taxes. First Commonwealth ordinarily generates an annual effective tax rate that is less than the statutory rate of 21% due to benefits resulting from tax-exempt interest, income from bank owned life insurance, and tax benefits associated with low-income housing tax credits. The consistent level of tax benefits that reduce First Commonwealth’s tax rate below the statutory rate produced an annual effective tax rate of 20% for each of the years ended December 31, 2023, 2022 and 2021. The tax effects of temporary differences between the financial statement carrying amounts and the tax bases of assets and liabilities that represent significant portions of the deferred tax assets and liabilities at December 31 are presented below: 2023 2022 (dollars in thousands) Deferred tax assets: Lease liability $ 10,542 $ 9,581 Allowance for credit losses 25,158 21,837 Postretirement benefits other than pensions 214 223 Unrealized loss on securities available for sale 30,469 36,673 Net operating loss carryforward 51 37 Deferred compensation 2,647 1,960 Accrued interest on nonaccrual loans 882 935 Accrued incentives 3,299 3,185 Unfunded loan commitments & other reserves 1,561 2,126 Purchase accounting adjustments 5,490 566 Other 738 953 Total deferred tax assets 81,051 78,076 Deferred tax liabilities: Loan origination fees and costs (1,252) (1,320) Right of use asset (9,618) (8,646) Depreciation of assets (1,484) (2,139) Section 197 intangibles (2,418) (1,717) Purchase accounting adjustments (3,321) (314) Other (228) (197) Total deferred tax liabilities (18,321) (14,333) Net deferred tax asset $ 62,730 $ 63,743 The Company has approximately $1.3 million of Pennsylvania net operating losses, which begin to expire in 2034. The Company expects to fully utilize the losses prior to expiration. Management assesses all available positive and negative evidence to estimate if sufficient future taxable income will be generated to utilize the existing deferred tax assets. Based on our evaluation, as of December 31, 2023, management has determined that no valuation allowance is necessary for the deferred tax assets because it is more likely than not that these assets will be realized through future reversals of existing temporary differences and future taxable income. In accordance with FASB ASC Topic 740-10, “Accounting for Uncertainty in Income Taxes,” the Company has no material unrecognized tax benefits or accrued interest and penalties as of December 31, 2023. We do not expect the total amount of unrecognized tax benefits to significantly increase in the next twelve months. The Company records interest and penalties on unrecognized tax benefits as a component of noninterest expense. First Commonwealth is subject to routine audits of our tax returns by the Internal Revenue Service (“IRS”) as well as all states in which we conduct business. Generally, tax years prior to the year ended December 31, 2020 are no longer open to examination by federal and state taxing authorities.

Retirement Benefits [Abstract]
Retirement Plans	Retirement Plans First Commonwealth has a savings plan pursuant to the provisions of section 401(k) of the Internal Revenue code. Effective January 1, 2020, a participating employee can receive a maximum matching contribution of 4% of their eligible compensation. In addition, each participating employee may contribute up to 80% of their eligible compensation to the plan. The 401(k) plan expense was $3.1 million in 2023, $2.9 million in 2022, and $3.0 million in 2021. First Commonwealth maintains a Non-Qualified Deferred Compensation Plan ( “ NQDC Plan ” ) to provide deferred compensation for those employees who are in the top 10% of full-time employees, as determined on the basis of eligible compensation. The NQDC Plan provides participants whose maximum retirement contribution is limited by IRS rules to defer additional compensation. Participants in the NQDC Plan are eligible to defer (on a pre-tax basis) from 1% to 25% of their eligible Plan compensation. Participants are also eligible to defer all or a portion of the Annual Incentive Plan (on a pre-tax basis) from 10% to 100% of their annual cash incentive earned. Effective January 1, 2020, an employer elective contribution is available to participants who reach the IRS Compensation limits in the 401(k) Plan. The ‘makeup match’ contribution is made to eligible participants on an annual basis. Effective January 1, 2021, an employer non-elective contribution is available to certain participants determined by the Company. The ‘discretionary’ contribution may be approved from year-to-year and allocated on an annual basis. There was $0.3 million and $0.2 million in NQDC Plan expense recognized in 2023 and 2022, respectively, and no NQDC Plan expense recognized in 2021. Select employees from former acquisitions were covered by postretirement benefit plans which provide medical and life insurance coverage. The measurement date for these plans was December 31. Postretirement Benefits Other than Pensions from Prior Acquisitions Net periodic benefit cost of these plans for the years ended December 31, was as follows: 2023 2022 2021 (dollars in thousands) Service cost $ — $ — $ — Interest cost on projected benefit obligation 25 35 23 Amortization of transition obligation — — — Amortization of prior service cost 76 75 76 Gain amortization (108) (96) (27) Net periodic benefit cost $ (7) $ 14 $ 72 The following table sets forth the change in the benefit obligation and plan assets as of December 31: 2023 2022 (dollars in thousands) Change in Benefit Obligation Benefit obligation at beginning of year $ 708 $ 986 Service cost — — Interest cost 35 22 Amendments — — Actuarial gain (119) (212) Net benefits paid (63) (88) Benefit obligation at end of year 561 708 Change in Plan Assets Fair value of plan assets at beginning of year — — Actual return on plan assets — — Employer contributions 63 88 Net benefits paid (63) (88) Fair value of plan assets at end of year — — Funded Status at End of Year 561 708 Unrecognized prior service cost (310) (386) Unrecognized net gain 750 728 Amounts recognized in retained earnings $ 1,001 $ 1,050 As of December 31, the funded status of the plan is: 2023 2022 (dollars in thousands) Amounts Recognized in the Statement of Financial Condition as Other liabilities $ 561 $ 708 The following table sets forth the amounts recognized in accumulated other comprehensive income that have not yet been recognized as components of net periodic benefit costs as of December 31: 2023 2022 2021 (dollars in thousands) Amounts recognized in accumulated other comprehensive income, net of tax: Net (gain) loss $ (590) $ (575) $ (461) Prior service cost 244 305 364 Total $ (346) $ (270) $ (97) Weighted-average assumptions used to determine the benefit obligation as of December 31 are as follows: 2023 2022 2021 Weighted-Average Assumptions Discount rate 4.90 % 5.31 % 2.38 % Health care cost trend: Initial 6.95 % 6.50 % 5.90 % Health care cost trend: Ultimate 4.75 % 4.75 % 4.75 % Year ultimate reached 2029 2028 2027 Weighted-average assumptions used to determine the net benefit costs as of December 31 are as follows: 2023 2022 2021 Weighted-Average Assumptions for Net Periodic Cost Discount rate 5.31 % 2.38 % 1.83 % Health care cost trend: Initial 6.50 % 5.90 % 5.95 % Health care cost trend: Ultimate 4.75 % 4.75 % 4.75 % Year ultimate reached 2028 2027 2026 Corridor 10.00 % 10.00 % 10.00 % Recognition period for gains and losses 9.3 9.9 10.4 The Medicare Prescription Drug, Improvement and Modernization Act of 2003 introduced a prescription drug benefit under Medicare Part D and a federal subsidy to sponsors of retiree health care benefit plans that provide a prescription drug benefit that is at least actuarially equivalent to Medicare Part D. The postretirement plans of First Commonwealth are provided through insurance coverage; therefore, First Commonwealth will not receive a direct federal subsidy. The preceding measures of the accumulated postretirement benefit cost assume that First Commonwealth will not receive the subsidy due to the relatively small number of retirees. As of December 31, 2023, the projected benefit payments for the next ten years are as follows: Projected Benefit (dollars in thousands) 2024 $ 83,837 2025 78,462 2026 73,542 2027 67,517 2028 61,396 2029 - 2033 219,643 The projected payments were calculated using the same assumptions as those used to calculate the benefit obligations included in this note. The estimated costs that will be amortized from accumulated other comprehensive income into net periodic cost for 2024 are as follows: Postretirement (dollars in thousands) Net gain $ (108) Prior service cost 76 Total $ (32)

Commitments and Contingencies Disclosure [Abstract]
Contingent Liabilities	Contingent Liabilities Legal proceedings First Commonwealth and its subsidiaries are subject in the normal course of business to various pending and threatened legal proceedings in which claims for monetary damages are asserted. As of December 31, 2023, management, after consultation with legal counsel, does not anticipate that the aggregate ultimate liability arising out of litigation pending or threatened against First Commonwealth or its subsidiaries will be material to First Commonwealth’s consolidated financial position. On at least a quarterly basis, First Commonwealth assesses its liabilities and contingencies in connection with such legal proceedings. For those matters where it is probable that First Commonwealth will incur losses and the amounts of the losses can be reasonably estimated, First Commonwealth records an expense and corresponding liability in its consolidated financial statements. To the extent the pending or threatened litigation could result in exposure in excess of that liability, the amount of such excess is not currently estimable. Although not considered probable, the range of reasonably possible losses for such matters in the aggregate, beyond the existing recorded liability (if any), is between $0 and $1 million. Although First Commonwealth does not believe that the outcome of pending litigation will be material to First Commonwealth’s consolidated financial position, it cannot rule out the possibility that such outcomes will be material to the consolidated results of operations and cash flows for a particular reporting period in the future.

Revenue Recognition (Notes)

Revenue Recognition (Notes)	12 Months Ended

Revenue Recognition and Deferred Revenue [Abstract]
Revenue Recognition	Revenue Recognition Substantially all of the Company’s revenue is generated from contracts with customers. Revenue associated with financial instruments, including revenue from loans and securities, certain noninterest income streams such as fees associated with derivatives are not in scope of FASB ASU Topic 606 - "Revenue from Contracts with Customers". Topic 606 is applicable to noninterest revenue streams such as trust income, service charges on deposits, insurance and retail brokerage commissions, card-related interchange income and gain(loss) on sale of OREO. For contracts within the scope of Topic 606, the Company immediately expenses contract acquisition costs when the asset that would have resulted from capitalizing these costs would have been amortized in one year or less. Noninterest revenue streams in-scope of Topic 606 are discussed below: Trust Income Trust income is primarily comprised of fees earned from the management and administration of trusts and other customer assets. The Company’s performance obligation is generally satisfied over time and the resulting fees are recognized monthly, based upon a tiered scale of market value of the assets under management at month-end. Payment is generally received a few days after month end through a direct charge to customers’ accounts. The Company does not earn performance-based incentives. Optional services such as financial planning or tax return preparation services are also available to trust customers. The Company’s performance obligation for these transactional-based services is generally satisfied and related revenue recognized, at a point in time. Payment is received shortly after services are rendered. Service Charges on Deposit Accounts Service charges on deposit accounts consist of fees earned from its deposit customers for transaction-based, account maintenance, overdraft services and account analysis fees. Transaction-based fees, which include services such as ATM use fees, stop payment fees, statement rendering and ACH fees, are recognized at the time the transaction is executed which is the point in time the Company fulfills the customer’s request. Monthly account maintenance fees are earned over the course of the month, representing the period over which the Company satisfies the performance obligation. Overdraft fees are recognized at the point in time that the overdraft occurs. The Company’s performance obligation for account analysis fees is generally satisfied, and the related revenue recognized, during the month the service is provided. Payment for service charges on deposit accounts is primarily received immediately or in the following month through a direct charge to customers’ accounts. Insurance and Retail Brokerage Commissions Insurance income primarily consists of commissions received from execution of personal, business and health insurance policies when acting as an agent on behalf of insurance carriers. The Company’s performance obligation is generally satisfied upon the issuance of the insurance policy. Because the Company’s contracts with the insurance carriers are generally cancellable by either party, with minimal notice, insurance commissions are recognized during the policy period as received. Also, the majority of insurance commissions are received on a monthly basis during the policy period, however some carriers pay the full annual commission to First Commonwealth at the time of policy issuance or renewal. In these cases, First Commonwealth would be required to refund any commissions it would not be entitled to as a result of cancelled or terminated policies. The Company has established a refund liability for the remaining term of the policies expected to be cancelled. The Company also receives incentive-based contingency fees from the insurance carriers. Contingency fee revenue, which totals approximately $0.5 million per year, is recognized as received due to the immaterial amount. Retail brokerage income primarily consists of commissions received on annuity and investment product sales through a third-party service provider. The Company’s performance obligation is generally satisfied upon the issuance of the annuity policy or the execution of an investment transaction. The Company does not earn a significant amount of trailer fees on annuity sales. However, after considering the factors impacting these trailer fees, such as the uncertainty of investor behavior and changes in the market value of assets, First Commonwealth determined that it would recognize trailing fees as received because it could not reasonably estimate an amount of future trailing commissions for which collection is probable. Commissions from the third-party service provider are received on a monthly basis based upon customer activity for the month. The fees are recognized monthly with a receivable until commissions are received from the third-party service provider the following month. Because the Company acts as an agent in arranging the relationship between the customer and the third-party service provider and does not control the services rendered to the customers, retail brokerage fees are presented net of related costs, including $4.2 million and $4.0 million, respectively, in commission expense as of December 31, 2023 and 2022. Card-Related Interchange Income Card-related interchange income is primarily comprised of debit and credit card income, ATM fees and merchant services income. Debit and credit card income is primarily comprised of interchange fees earned whenever the Company’s debit and credit cards are processed through card payment networks such as MasterCard. ATM fees are primarily generated when a Company cardholder uses a non-Company ATM or a non-Company cardholder uses a Company ATM. Merchant services income mainly represents fees charged to merchants to process their debit and credit card transactions, in addition to account management fees. Card-related interchange income is recognized at the point in time as the customer transactions are settled. Other Income Other income includes service revenue from processing wire transfers, bill pay service, cashier’s checks, and other services. The Company’s performance obligation for these services are largely satisfied, and related revenue recognized, when the services are rendered or upon completion. Payment is typically received immediately or in the following month. Gains(losses) on sales of OREO First Commonwealth records a gain or loss from the sale of OREO when control of the property transfers to the buyer, which generally occurs at the time of an executed deed. When First Commonwealth finances the sale of OREO to the buyer, an assessment of whether the buyer is committed to perform their obligations under the contract is completed along with an evaluation of whether collectability of the transaction price is probable. Once these criteria are met, the OREO asset is derecognized and the gain or loss on sale is recorded upon transfer of control of the property to the buyer. In determining the gain or loss on the sale, First Commonwealth adjusts the transaction price and related gain(loss) on sale if a significant financing component is present. The following presents noninterest income, segregated by revenue streams in-scope and out-of-scope of Topic 606 for the year ended December 31: 2023 2022 2021 (dollars in thousands) Noninterest Income In-scope of Topic 606: Trust income $ 10,516 $ 10,518 $ 11,111 Service charges on deposit accounts 21,437 19,641 17,984 Insurance and retail brokerage commissions 9,628 8,857 8,502 Card-related interchange income 28,640 27,603 27,954 Gain on sale of other loans and assets 331 455 753 Other income 4,323 4,036 4,184 Noninterest Income (in-scope of Topic 606) 74,875 71,110 70,488 Noninterest Income (out-of-scope of Topic 606) 21,734 27,598 36,269 Total Noninterest Income $ 96,609 $ 98,708 $ 106,757

Related Party Transactions	Related Party Transactions Some of First Commonwealth’s directors, executive officers, principal shareholders and their related interests had transactions with the subsidiary bank in the ordinary course of business. All deposit and loan transactions were made on substantially the same terms, such as collateral and interest rates, as those prevailing at the time for comparable transactions. In the opinion of management, these transactions do not involve more than the normal risk of collectability nor do they present other unfavorable features. It is anticipated that similar transactions will be entered into in the future.

Broker-Dealer, Net Capital Requirement, SEC Regulation [Abstract]
Regulatory Restrictions and Capital Adequacy	Regulatory Restrictions and Capital Adequacy The amount of funds available to the parent from its subsidiary bank is limited by restrictions imposed on all depository institutions by banking regulation that restricts and limits the payment of dividends and the ability of depository institutions to engage in transactions, including lending transactions and asset purchases, with affiliates. First Commonwealth and First Commonwealth Bank are subject to various regulatory capital requirements administered by the federal banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory and possibly additional discretionary actions by regulators which, if undertaken, could have a direct material effect on First Commonwealth’s financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, First Commonwealth and First Commonwealth Bank must meet specific capital guidelines that involve quantitative measures of First Commonwealth’s assets, liabilities and certain off-balance sheet items as calculated under regulatory accounting practices. First Commonwealth’s capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk weighting and other factors. Effective January 1, 2015, First Commonwealth became subject to regulatory risk-based capital rules adopted by the federal banking agencies implementing Basel III. The capital rules require First Commonwealth to maintain the following minimum capital levels: • a minimum Tier I capital to risk-weighted assets of at least 6.0%, plus a capital conservation buffer of 2.5%, resulting in a required minimum ratio of 8.5% • a minimum Common Equity Tier 1 to risk weighted assets of at least 4.5%, plus the capital conservation buffer of 2.5%, resulting in a required minimum ratio of 7%. • a minimum Total Capital to risk weighted assets of at least 8.0%, plus the 2.5% capital conservation buffer, resulting in a required minimum of 10.5% • a minimum Leverage ratio, which is Tier 1 capital to adjusted average assets, of 4.0% The capital conservation buffer may only include capital that qualifies as Common Equity Tier 1. The Basel III Rules also permit banking organizations with less than $15.0 billion in assets to retain, through a one-time election, the exclusion of accumulated other comprehensive income from regulatory capital. The Company elected to retain this treatment, which reduces the volatility of regulatory capital levels. In 2018, First Commonwealth Bank, the Company's banking subsidiary, issued $100 million in subordinated debt, which under regulatory rules qualifies as Tier II capital. As of December 31, 2023, this subordinated debt issuance increased the total risk-based capital ratio by 94 basis points. In March 2020, regulators issued interim financial rule (“IFR”) “Regulatory Capital Rule: Revised Transition of the Current Expected Losses Methodology for Allowances” in response to the disrupted economic activity from the pandemic. The IFR provides financial institutions that adopt CECL during 2020 with the option to delay for two years the estimated impact of CECL on regulatory capital, followed by a three-year transition period to phase out the aggregate amount of the capital benefit provided by the initial two-year delay (“five-year transition”). The Company adopted CECL effective January 1, 2020 and elected to implement the five-year transition. Regulatory capital levels without the capital benefit at December 31, 2023 for both First Commonwealth and First Commonwealth Bank would have continued to be greater than the amounts needed to be considered “well capitalized”, as the transition provided a capital benefit of approximately 11 to 12 basis points. As of December 31, 2023 and 2022, First Commonwealth and First Commonwealth Bank met all capital adequacy requirements to which they are subject and were considered well-capitalized under the regulatory rules. To be considered well capitalized, the Company must maintain minimum Total risk-based capital, Tier I risk-based capital, Tier I leverage ratio and Common equity tier I risk-based capital as set for in the tables below: Actual Minimum Capital Required Required to be Considered Well Capital Ratio Capital Ratio Capital Ratio (dollars in thousands) As of December 31, 2023 Total Capital to Risk Weighted Assets First Commonwealth Financial Corporation $ 1,314,021 13.93 % $ 990,508 10.50 % $ 943,341 10.00 % First Commonwealth Bank 1,222,182 13.01 986,558 10.50 939,579 10.00 Tier I Capital to Risk Weighted Assets First Commonwealth Financial Corporation $ 1,122,814 11.90 % $ 801,840 8.50 % $ 754,673 8.00 % First Commonwealth Bank 1,030,975 10.97 798,642 8.50 751,663 8.00 Tier I Capital to Average Assets First Commonwealth Financial Corporation $ 1,122,814 10.04 % $ 447,542 4.00 % $ 559,427 5.00 % First Commonwealth Bank 1,030,975 9.24 446,530 4.00 558,163 5.00 Common Equity Tier I to Risk Weighted Assets First Commonwealth Financial Corporation $ 1,052,814 11.16 % $ 660,339 7.00 % $ 613,172 6.50 % First Commonwealth Bank 1,030,975 10.97 657,705 7.00 610,727 6.50 Actual Minimum Capital Required Required to be Considered Well Capital Ratio Capital Ratio Capital Ratio (dollars in thousands) As of December 31, 2022 Total Capital to Risk Weighted Assets First Commonwealth Financial Corporation $ 1,160,053 14.36 % $ 848,288 10.50 % $ 807,893 10.00 % First Commonwealth Bank 1,100,529 13.65 846,593 10.50 806,279 10.00 Tier I Capital to Risk Weighted Assets First Commonwealth Financial Corporation $ 966,072 11.96 % $ 686,709 8.50 % $ 646,314 8.00 % First Commonwealth Bank 906,548 11.24 685,337 8.50 645,023 8.00 Tier I Capital to Average Assets First Commonwealth Financial Corporation $ 966,072 10.18 % $ 379,527 4.00 % $ 474,408 5.00 % First Commonwealth Bank 906,548 9.58 378,578 4.00 473,223 5.00 Common Equity Tier I to Risk Weighted Assets First Commonwealth Financial Corporation $ 896,072 11.09 % $ 565,525 7.00 % $ 525,131 6.50 % First Commonwealth Bank 906,548 11.24 564,395 7.00 524,081 6.50

Capital	Capital At December 31, 2023, shareholders’ equity was $1.3 billion, an increase of $262.2 million from December 31, 2022. The increase was due to $141.4 million in common stock issued in connection with the Centric acquisition, $157.1 million in net income and a $25.9 million increase in the fair value of available for sale securities. This was partially offset by $50.8 million of dividends paid to shareholders and $15.1 million of common stock repurchases. Cash dividends declared per common share were $0.495, $0.475 and $0.455 for the years ended December 31, 2023, 2022 and 2021, respectively.

Statement of Accounting Policies (Policies)	12 Months Ended

Accounting Policies [Abstract]
Business Combinations Policy [Policy Text Block]	Business Combinations Business combinations are accounted for by using the acquisition method of accounting. Under the acquisition method, identifiable assets acquired and liabilities assumed at the acquisition date are measured at their fair values as of that date, and are recognized separately from goodwill. The difference between the purchase price and the fair value of the net assets acquired is recorded as goodwill. Results of operations of the acquired entities are included in the Consolidated Statements of Income from the date of acquisition. Acquisition costs are expensed when incurred.
General	General The following summary of accounting and reporting policies is presented to aid the reader in obtaining a better understanding of the consolidated financial statements of First Commonwealth Financial Corporation and its subsidiaries (“First Commonwealth”) contained in this report. First Commonwealth's subsidiaries include First Commonwealth Bank ("FCB" or the "Bank"), First Commonwealth Insurance Agency, Inc. ("FCIA"), FRAMAL and First Commonwealth Financial Advisors, Inc. ("FCFA"). The financial information is presented in accordance with generally accepted accounting principles and general practice for financial institutions in the United States of America. In preparing financial statements, management is required to make estimates and assumptions that affect the reported amount of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements. In addition, these estimates and assumptions affect revenues and expenses in the financial statements and as such, actual results could differ from those estimates. Through its subsidiaries, which include a commercial bank and an insurance agency, First Commonwealth provides a full range of loan, deposit, trust, insurance and personal financial planning services primarily to individuals and small to middle market businesses in 30 counties in central and western Pennsylvania as well as throughout Ohio. First Commonwealth has determined that it has one business segment. First Commonwealth is subject to regulations of certain state and federal agencies. These regulatory agencies periodically examine First Commonwealth for adherence to laws and regulations.
Basis of Presentation	Basis of Presentation The accompanying Consolidated Financial Statements include the accounts of First Commonwealth previously defined above. All material intercompany transactions have been eliminated in consolidation. Certain prior period amounts have been reclassified to conform to the current period's presentation. Equity investments of less than a majority but at least 20% ownership are accounted for by the equity method and classified as “Other assets.” Earnings on these investments are reflected in “Other income” on the Consolidated Statements of Income, as appropriate, in the period earned.
Securities	Securities Debt securities that First Commonwealth has the positive intent and ability to hold to maturity are classified as securities held to maturity and are reported at amortized cost adjusted for amortization of premium and accretion of discount on a level yield basis. Debt and equity securities that are bought and held principally for the purpose of selling them in the near term are to be classified as trading securities and reported at fair value, with unrealized gains and losses included in earnings. Debt securities not classified as either held-to-maturity securities or trading securities are classified as securities available for sale and are reported at fair value, with unrealized gains and losses that are not related to impairment excluded from earnings and reported as a component of other comprehensive income, which is included in shareholders’ equity, net of deferred taxes. First Commonwealth has securities classified as held to maturity and available for sale and does not engage in trading activities. First Commonwealth utilizes the specific identification method to determine the net gain or loss on debt securities and the average cost method to determine the net gain or loss on the equity securities. First Commonwealth conducts a comprehensive review of the investment portfolio on a quarterly basis to evaluate for expected credit losses. When evaluating available-for-sale securities, management first considers whether we intend to sell the security, or if it is more likely than not that we will be required to sell the security before recovery of its amortized cost basis. If there is intent to sell, the security's amortized cost is written down to fair value through income. Otherwise, available-for-sale securities whose market values have fallen below their book value are evaluated at the issuer-specific level to determine if the decline in value is a result of credit losses. Issuer-specific securities include obligations of U.S. Government agencies and sponsored enterprises, single issue trust preferred securities, corporate debentures and obligations of states and political subdivisions. Further analysis of these securities includes a review of research reports, analysts’ recommendations, credit rating changes, news stories, annual reports, impact of interest rate changes and any other relevant information pertaining to the affected security. Any loss not determined to be a credit loss is recorded as a reduction to shareholders equity, through other comprehensive income. Held-to-maturity securities are evaluated for impairment on an annual basis, using historical probability of default and loss given default information specific to the investment category. On a quarterly basis, a qualitative review is completed incorporating changes to the mix and credit quality of the investment portfolio. If this evaluation determines that credit losses exist an allowance for credit loss is recorded and included in earnings as a component of credit loss expense.
Financing Receivable, Held-for-sale [Policy Text Block]	Mortgage Loans Held for Sale
Loans	Loans Loans are carried at the principal amount outstanding. Interest is accrued as earned. Loans held for sale are carried at the lower of cost or fair market value determined on an individual basis. First Commonwealth considers a loan to be past due and still accruing interest when payment of interest or principal is contractually past due but the loan is both well secured and in the process of collection. For installment, mortgage, term and other loans with amortizing payments that are scheduled monthly, 90 days past due is reached when four monthly payments are due and unpaid. For demand, time and other multi-payment obligations with payments scheduled other than monthly, delinquency status is calculated using number of days instead of number of payments. Revolving credit loans, including personal credit lines and home equity lines, are considered to be 90 days past due when the borrower has not made the minimum payment for four monthly cycles. A loan is placed in nonaccrual status when, based on current information and events, it is probable that First Commonwealth will be unable to fully collect principal or interest due according to the contractual terms of the loan. A loan is also placed in nonaccrual status when, based on regulatory definitions, the loan is maintained on a “cash basis” due to the weakened financial condition of the borrower. When a determination is made to place a loan in nonaccrual status, all accrued and unpaid interest is reversed. Nonaccrual loans are restored to accrual status when, based on a sustained period of repayment by the borrower in accordance with the contractual terms of the loan, First Commonwealth expects repayment of the remaining contractual principal and interest or when the loan otherwise becomes well-secured and in the process of collection. First Commonwealth adopted ASU 2022-02 on January 1, 2023 on a prospective basis. As a result, only periods prior to this date would include loans classified as troubled debt restructured loan ("TDR"). A loan is considered to be a TDR when the loan terms have been renegotiated to provide a reduction or deferral of principal or interest as a result of the financial difficulties experienced by the borrower, who could not obtain comparable terms from alternate financing sources. During those periods, TDR loans are considered to be nonperforming loans. A loan is considered to be nonperforming when, based on current information and events, it is expected that First Commonwealth will be unable to collect principal or interest that is due in accordance with contractual terms of the loan. Expected losses on nonperforming loans are measured based on the present value of expected cash flows discounted at the loan’s effective interest rate or, as a practical expedient, at the loan’s observable market price or the fair value of the collateral if the loan is collateral dependent. For loans other than those that First Commonwealth expects repayment through liquidation of the collateral, when the remaining recorded investment in the loan is less than or equal to the present value of the expected cash flows, income is applied as a reduction to loan principal rather than interest income. Loans deemed uncollectible are charged off through the allowance for credit losses. Factors considered in assessing ultimate collectability include past due status, financial condition of the borrower, collateral values and debt covenants including secondary sources of repayment by guarantors. Payments received on previously charged off loans are recorded as recoveries in the allowance for credit losses. Acquired Loans Acquired loans are recorded at estimated fair value on the date of acquisition with no carryover of the related allowance for credit losses. The fair value of acquired loans is determined by estimating the principal and interest cash flows expected to be collected on the loans and discounting those cash flows at a market rate of interest. The estimated fair value considers factors such as loan term, internal risk rating, delinquency status, prepayment rates, estimated value of the underlying collateral and the current interest rate environment. Acquired loans are classified into two categories: PCD loans and non-PCD loans. PCD loans are defined as a loan or group of loans that have experienced more than insignificant credit deterioration since origination. Non-PCD loans will have an allowance for credit losses established on acquisition date, which is recognized as an expense through provision for credit losses. For PCD loans, an allowance for credit losses is recognized on day 1 by adding it to the fair value of the loan, which is the “Day 1 amortized cost”. There is no provision for credit loss expense recognized on PCD loans because the initial allowance for credit losses is established by grossing-up the amortized cost of the PCD loan.
Loan Fees	Loan Fees Loan origination and commitment fees, net of associated direct costs, are deferred and the net amount is amortized as an adjustment to the related loan yield on the interest method, generally over the contractual life of the related loans or commitments.
Other Real Estate Owned	Other Real Estate Owned
Allowance for Credit Losses	Allowance for Credit Losses for Loans and Leases When determining the allowance for credit losses, our loan and lease portfolio includes five primary loan categories with fourteen segments. Refer to Note 9, "Loans and Leases and Allowance for Credit Losses" for further discussion of these portfolio segments. The allowance for credit losses is calculated by pooling loans of similar credit risk characteristics and applying a discounted cash flow methodology after incorporating probability of default and loss given default estimates. Probability of default represents an estimate of the likelihood of default and loss given default measures the expected loss upon default. Inputs impacting the expected losses includes a forecast of macroeconomic factors, using a weighted forecast from a nationally recognized firm. Our model incorporates a one-year forecast of macroeconomic factors, after which the factors revert back to the historical mean over a one-year period. All nonperforming credits in excess of $250 thousand are individually evaluated on a quarterly basis. A specific reserve is established for individually evaluated loans in an amount equal to the total amount of estimated losses for the loans that are reviewed. Based on this reserve as a percentage of reviewed loan balances, a reserve is also established for the nonperforming loan balances that are not individually reviewed. An additional component of the allowance is determined by management based on a qualitative analysis of certain factors related to portfolio risks that are not incorporated in the calculated model. Factors considered by management include lending practices, ability and experience of the credit staff, the overall lending environment and external factors such as the regulatory environment and competition. Portfolio risks include unusual changes or recent trends in specific portfolios such as unexpected changes in the trends or levels of delinquency. No matter how detailed an analysis of potential credit losses is performed, these estimates are inherently imprecise. Management must make estimates using assumptions and information that is often subjective and changes rapidly. First Commonwealth made the accounting policy election to exclude accrued interest from the allowance for credit loss calculation because these balances are written off or reversed when a loan is placed in non-accrual status.
Allowance for Off-Balance Sheet Credit Exposures	Allowance for Off-Balance Sheet Credit Exposures
Bank Owned Life Insurance	Bank Owned Life Insurance
Premises and Equipment	Premises, Equipment and Lease Commitments Premises and equipment are carried at cost less accumulated depreciation on First Commonwealth’s Consolidated Statements of Financial Condition. Depreciation is computed on the straight-line and accelerated methods over the estimated useful life of the asset. A straight-line depreciation method was used for substantially all furniture and equipment as well as buildings and improvements. Charges for maintenance and repairs are expensed as incurred. Leasehold improvements are expensed over the term of the lease or the estimated useful life of the improvement, whichever is shorter.
Goodwill	Goodwill Intangible assets resulting from acquisitions under the purchase method of accounting consist of goodwill and other intangible assets (see “Other Intangible Assets” section below). Goodwill is not amortized and is subject to at least annual assessments for impairment. First Commonwealth reviews goodwill annually and again at any quarter-end if a material event occurs during the quarter that may affect goodwill. When circumstances indicate that it is more likely than not that fair value is less than carrying value, a triggering event has occurred and a quantitative impairment test is performed. Goodwill is evaluated for potential impairment by determining if our fair value has fallen below carrying value.
Other Intangible Assets	Other Intangible Assets Other intangible assets consist of core deposits and customer lists obtained through acquisitions. Core deposit intangibles are amortized over their estimated lives using the present value of the benefit of the core deposits and straight-line methods of amortization. Customer list intangibles are amortized over the expected lives using expected cash flows based on retention of the customer base. These intangibles are evaluated for impairment on an annual basis and when events or changes in circumstances indicate that the carrying amount may not be recoverable.
Accounting for the Impairment of Long-Lived Assets	Accounting for the Impairment of Long-Lived Assets First Commonwealth reviews long-lived assets, such as premises and equipment and intangibles, for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. These changes in circumstances may include a significant decrease in the market value of an asset or the extent or manner in which an asset is used. If there is an indication that the carrying amount of an asset may not be recoverable, future undiscounted cash flows expected to result from the use of the asset are estimated. If the sum of the expected cash flows is less than the carrying value of the asset, a loss is recognized for the difference between the carrying value and fair value of the asset. Long-lived assets classified as held for sale are measured at the lower of their carrying amount or fair value less cost to sell. Depreciation or amortization is discontinued on long-lived assets classified as held for sale.
Income Taxes	Income Taxes
Comprehensive Income Disclosures	Comprehensive Income Disclosures
Cash and Cash Equivalents	Cash and Cash Equivalents For purposes of reporting cash flows, cash and cash equivalents include cash on hand, amounts due from banks, federal funds sold and interest-bearing bank deposits. Generally, federal funds are sold for one-day periods.
Derivatives and Hedging Activities	Derivatives and Hedging Activities First Commonwealth accounts for derivative instruments and hedging activities in accordance with FASB ASC Topic 815, “Derivatives and Hedging" ("Topic 815"). All derivatives are evaluated at inception as to whether or not they are hedging or non-hedging activities, and appropriate documentation is maintained to support the final determination. First Commonwealth recognizes all derivatives as either assets or liabilities on the Consolidated Statements of Financial Condition and measures those instruments at fair value. For derivatives designated as fair value hedges, changes in the fair value of the derivative and the hedged item related to the hedged risk are recognized in earnings. Any hedge ineffectiveness would be recognized in the income statement line item pertaining to the hedged item. For derivatives designated as cash flow hedges, changes in fair value of the effective portion of the cash flow hedges are reported in other comprehensive income ("OCI"). When the cash flows associated with the hedged item are realized, the gain or loss included in OCI is recognized in the Consolidated Statement of Income. When First Commonwealth purchases a portion of a commercial loan that has an existing interest rate swap, it enters a risk participation agreement with the counterparty and assumes the credit risk of the loan customer related to the swap. Any fee paid to First Commonwealth as a result of the risk participation agreement is offset by credit risk of the counterparties and is recognized in the income statement. Credit risk on the risk participation agreements is determined after considering the risk rating, probability of default and loss given default of the counterparties. Management periodically reviews contracts from various functional areas of First Commonwealth to identify potential derivatives embedded within selected contracts. As of December 31, 2023, First Commonwealth has interest rate derivative positions that are designated as hedging instruments and others that are not designated as hedging instruments. See Note 7, “Derivatives,” for a description of these instruments.
Earnings Per Common Share	Earnings Per Common Share Basic earnings per share excludes dilution and is computed by dividing income available to common shareholders by the weighted-average number of common shares outstanding for the period. Diluted earnings per share reflects the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock or resulted in the issuance of common stock that then shared in the earnings of the entity. For all periods presented, the dilutive effect on average shares outstanding is the result of unvested restricted stock grants.
Fair Value Measurements	Fair Value Measurements In accordance with FASB ASC Topic 820, “Fair Value Measurements and Disclosures" ("Topic 820"), First Commonwealth groups financial assets and financial liabilities measured at fair value into three levels, based on the markets in which the assets and liabilities are traded and the reliability of the assumptions used to determine fair value. These levels are: • Level 1—Valuations for assets and liabilities traded in active exchange markets, such as the New York Stock Exchange ("NYSE"). Valuations are obtained from readily available pricing sources for market transactions involving identical assets or liabilities. • Level 2—Valuations for assets and liabilities traded in less active dealer or broker markets. Valuations are obtained for identical or comparable assets or liabilities from alternative pricing sources with reasonable levels of price transparency. Level 2 securities include U.S. Government securities issued by Agencies and Sponsored Enterprises, Obligations of States and Political Subdivisions, certain corporate securities, FHLB stock, loans held for sale, interest rate derivatives that include interest rate swaps, risk participation agreements and foreign currency contracts, certain other real estate owned and certain nonperforming loans. • Level 3—Valuations for assets and liabilities that are derived from other valuation methodologies, including option pricing models, discounted cash flow models and similar techniques, and not based on market exchange, dealer or broker traded transactions. If the inputs used to provide the evaluation are unobservable and/or there is very little, if any, market activity for the security or similar securities, the securities would be considered Level 3 securities. Level 3 valuations incorporate certain assumptions and projections in determining the fair value assigned to such assets or liabilities. The assets included in Level 3 are nonmarketable equity investments, certain other real estate owned and certain nonperforming loans. In general, fair values of financial instruments are based upon quoted market prices, where available. If such quoted market prices are not available, fair value is based upon pricing models that primarily use, as inputs, observable market-based parameters. Valuation adjustments may be made to ensure that financial instruments are recorded at fair value. These adjustments may include amounts to reflect counterparty credit quality and our creditworthiness, among other things, as well as unobservable parameters. Any such valuation adjustments are applied consistently over time. See Note 17 “Fair Values of Assets and Liabilities” for additional information.
Revenue from Contract with Customer [Policy Text Block]	Revenue from Contracts with Customers First Commonwealth records revenue from contracts with customers in accordance with ASC Topic 606, “Revenue from Contracts with Customers” (“Topic 606”). Under Topic 606, the Company must identify the contract with a customer, identify the performance obligations in the contract, determine the transaction price, allocate the transaction price to the performance obligations in the contract, and recognize revenue when (or as) the Company satisfies a performance obligation. A significant component of the Company's revenue, net interest earned on financial assets and liabilities, is excluded from the scope of Topic 606. First Commonwealth generally fully satisfies its performance obligations on its contracts with customers as services are rendered and the transaction prices are typically fixed; charged either on a periodic basis or based on activity. Because performance obligations are satisfied as services are rendered and the transaction prices are fixed, the Company has made no significant judgments in applying the revenue guidance prescribed in Topic 606 that affect the determination of the amount and timing of revenue from contracts with customers.
Lessee, Leases	A right-of-use asset and related lease liability is recognized on the Consolidated Statements of Financial Condition for operating leases First Commonwealth has entered to lease certain office facilities. These amounts are reported as components of premises and equipment and other liabilities. Short-term operating leases, which are leases with an original term of 12 months or less and do not have a purchase option that is likely to be exercised, are not recognized as part of the right-of-use asset or lease liability. First Commonwealth has no material leasing arrangements for which it is the lessor of property or equipment.

Recorded Investment and Unpaid Principal Balance for Impaired Loans with Associated Allowance	The following tables include the recorded investment and unpaid principal balance for nonperforming loans with the associated allowance amount, if applicable, as of December 31, 2023 and 2022. Also presented are the average recorded investment in nonperforming loans and the related amount of interest recognized while the loan was considered nonperforming.
