Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation The accounting and reporting policies of First Commonwealth Financial Corporation and subsidiaries (“First Commonwealth” or the “Company”) conform with generally accepted accounting principles in the United States of America (“GAAP”). The preparation of financial statements in conformity with GAAP requires management to make estimates, assumptions and judgments that affect the amounts reported in the financial statements and accompanying notes. Actual realized amounts could differ from those estimates. In the opinion of management, the unaudited interim consolidated financial statements include all adjustments (consisting of only normal recurring adjustments) necessary for a fair presentation of First Commonwealth’s financial position, results of operations, comprehensive income, cash flows and changes in shareholders’ equity as of and for the periods presented. Certain information and Note disclosures normally included in Consolidated Financial Statements prepared in accordance with GAAP have been condensed or omitted pursuant to the rules and regulations of the SEC. 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.

Business Combination and Asset Acquisition [Abstract]
Business Combination Disclosure	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- purchased credit-deteriorated ("non-PCD") loans and on an individual basis for purchased credit-deteriorated ("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 February 1, 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.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingent Liabilities	Commitments and Contingent Liabilities Commitments and Letters of Credit 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 of 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 the date shown below: September 30, 2023 December 31, 2022 (dollars in thousands) Financial instruments whose contract amounts represent credit risk: Commitments to extend credit $ 2,525,601 $ 2,356,539 Financial standby letters of credit 12,265 18,417 Performance standby letters of credit 15,801 12,853 Commercial letters of credit 161 573 The notional amounts outstanding as of September 30, 2023 include amounts issued in 2023 of $0.9 million in performance standby letters of credit and $0.3 million in financial standby letters of credit. There were no commercial letters of credit issued in 2023. A liability of $0.1 million has been recorded as of both September 30, 2023 and December 31, 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 related to these commitments resulted in the recording of a liability of $8.9 million and $10.0 million as of September 30, 2023 and December 31, 2022, respectively. This liability is reflected in "Other liabilities" in the unaudited 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 as well as estimated utilization for each loan category. 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 September 30, 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.

These obligations have contractual maturities ranging from less than one year to approximately 40 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.

Securities held to maturity with an amortized cost of $119.2 million and $368.8 million were pledged as of September 30, 2023 and December 31, 2022, respectively, to secure public deposits and for other purposes required or permitted by law. Other Investments As a member of the Federal Home Loan Bank ("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 September 30, 2023 and December 31, 2022, our FHLB stock totaled $42.8 million and $25.2 million, respectively, and is included in “Other investments” on the unaudited 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 during the three and nine months ended September 30, 2023. As of both September 30, 2023 and December 31, 2022, "Other investments" also includes $6.2 million and $1.2 million, respectively, in equity securities. These securities do not have a readily determinable fair value and are carried at cost. During the nine-months ended September 30, 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 the severity and duration of decline in estimated fair value, 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 September 30, 2023 for both available for sale and held to maturity securities by investment category and time frame for which 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 $ 633 $ (15) $ 3,233 $ (526) $ 3,866 $ (541) Mortgage-Backed Securities – Commercial 95,858 (1,190) 293,015 (80,472) 388,873 (81,662) Obligations of U.S. Government-Sponsored Enterprises: Mortgage-Backed Securities – Residential 3,042 (79) 628,596 (151,986) 631,638 (152,065) Mortgage-Backed Securities – Commercial — — 2,798 (55) 2,798 (55) Other Government-Sponsored Enterprises — — 18,143 (5,318) 18,143 (5,318) Obligations of States and Political Subdivisions 4,526 (177) 26,284 (4,856) 30,810 (5,033) Debt Securities Issued by Foreign Governments 195 (5) 753 (47) 948 (52) Corporate Securities 8,552 (202) 20,917 (4,082) 29,469 (4,284) Total Securities $ 112,806 $ (1,668) $ 993,739 $ (247,342) $ 1,106,545 $ (249,010) At September 30, 2023, fixed income securities issued by the U.S. Government and U.S. Government-sponsored enterprises comprised 96% of total unrealized losses. All unrealized losses are the result of changes in market interest rates. At September 30, 2023, there are 231 debt securities in an unrealized loss position.

As of December 31, 2022, our corporate securities had an amortized cost and estimated fair value of $32.0 million and $29.2 million, respectively. Corporate securities are comprised of debt issued by large regional banks. There were eight and six corporate securities, respectively, in an unrealized loss position as of September 30, 2023 and December 31, 2022. When unrealized losses exist, management reviews each of the issuer’s asset quality, earnings trends 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. There was no expected credit related impairment recognized on investment securities during the nine months ended September 30, 2023 and 2022.

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 September 30, 2023 and December 31, 2022, this category includes $0.9 million and $4.3 million 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. Nonowner Occupied - Consists of loans secured by non-owner occupied commercial real estate 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 owner occupied commercial real estate 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 3.78% and during the one-year forecast period it was projected to average 4.59%, with a peak of 4.86%. 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 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 Company’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. The following tables represent our credit risk profile by creditworthiness: September 30, 2023 Non-Pass Pass OAEM Substandard Doubtful Loss Total Non-Pass Total (dollars in thousands) Commercial,

Portfolio Risks The credit quality of our loan portfolio 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 net charge-offs for the nine months ended September 30, 2023 and 2022 were $13.8 million and $5.1 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 September 30, 2023 and December 31, 2022.

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 on 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 becomes 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 for repayment of 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 that 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. At September 30, 2023 and December 31, 2022, there were no nonperforming loans held for sale. During both the nine months ended September 30, 2023 and 2022, there were no gains recognized on the sale of nonperforming loans. The following tables include the recorded investment and unpaid principal balance for nonperforming loans with the associated allowance amount, if applicable, as of September 30, 2023 and December 31, 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 using month-end balances of the loans for the period reported and are included in the table below based on their period-end allowance position. The increase in nonperforming loans is primarily a result of $22.0 million in loans acquired from Centric, offset by the removal of $6.4 million in accruing troubled debt restructurings ("TDR's"). The TDR's were eliminated as a result of our adoption of ASU 2022-02, Financial Instruments Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures ("ASU 2022-02"). This standard was adopted on January 1, 2023 and eliminates the accounting guidance for TDR's while enhancing disclosure requirements for loan modifications for borrowers experiencing financial difficulty.

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. The following tables present the amortized cost basis of loan modifications made to borrowers experiencing financial difficulty: For the Nine Months Ended September 30, 2023 Rate Reduction Term Extension Principal Forgiveness Term Extension and Payment Deferral To

Leases [Abstract]
Lessee, Operating Leases [Text Block]	LeasesFirst Commonwealth has elected to apply certain practical expedients provided 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; and (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, including 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 unaudited Consolidated Statements of Condition classification of the Company’s right of use ("ROU") assets and lease liabilities, lease costs and other lease information. September 30, 2023 December 31, 2022 Balance sheet: Operating lease asset classified as premises and equipment $ 45,783 $ 40,747 Operating lease liability classified as other liabilities 50,155 45,149 For the Three Months Ended For the Nine Months Ended September 30, 2023 September 30, 2022 September 30, 2023 September 30, 2022 Income statement: Operating lease cost classified as occupancy and equipment expense $ 1,521 $ 1,259 $ 4,565 $ 3,727 Weighted average lease term, in years 13.37 14.10 Weighted average discount rate 3.51 % 3.28 % Operating cash flows $ 1,571 $ 1,245 In the above table, the increase in the ROU asset and lease liability at September 30, 2023 compared to December 31, 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 Federal Home Loan Bank ("FHLB") of Pittsburgh. This rate is consistent with a collateralized borrowing rate and is available for terms similar to the lease payment schedules. Future minimum payments for operating leases with initial or remaining terms of one year or more as of September 30, 2023 were as follows (dollars in thousands): For the twelve months ended: September 30, 2024 $ 5,847 September 30, 2025 5,621 September 30, 2026 5,160 September 30, 2027 4,909 September 30, 2028 4,672 Thereafter 37,922 Total future minimum lease payments 64,131 Less remaining imputed interest 13,976 Operating lease liability $ 50,155

Income Tax Disclosure	Income Taxes In accordance with FASB ASC Topic 740-10, “Accounting for Uncertainty in Income Taxes,” at September 30, 2023 and December 31, 2022, First Commonwealth had no material unrecognized tax benefits or accrued interest and penalties. If applicable, First Commonwealth will record interest and penalties 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, 2019 are no longer open to examination by federal and state taxing authorities.

Fair Values of Assets and Liabi

Fair Values of Assets and Liabilities	9 Months Ended

Fair Value Disclosures [Abstract]
Fair Values of Assets and Liabilities	Fair Values of Assets and Liabilities FASB ASC Topic 820, “Fair Value Measurements and Disclosures” ("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 unaudited Consolidated Statements of Financial Condition or in the “Other assets” category of the unaudited 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: • 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 observable inputs for identical or comparable assets or liabilities from alternative pricing sources with reasonable levels of price transparency. Level 2 includes Obligations of U.S. Government securities issued by Agencies and Sponsored Enterprises, Obligations of States and Political Subdivisions, corporate securities, FHLB stock, loans held for sale, premise held for sale, interest rate derivatives (including interest rate caps, interest rate collars, interest rate swaps and risk participation agreements), certain other real estate owned and certain nonperforming loans. 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 recorded in the unaudited Consolidated Statements of Financial Condition are primarily comprised of FHLB stock whose estimated fair value is based on its par value. Additional information on FHLB stock is provided in Note 7, “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 or 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, and consist of interest rate swaps where there is no significant deterioration in the counterparties' and/or 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 Secured Overnight Financing Rate ("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 12, “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. 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. • 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 valuation 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 non-marketable equity investments, certain interest rate derivatives and certain nonperforming loans. The estimated fair value of 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 the credit quality of the underlying counterparties (loan customers). In accordance with ASU No. 2011-04, the following table provides information related to quantitative inputs and assumptions used in Level 3 fair value measurements. Fair Value (dollars Valuation Unobservable Inputs Range / September 30, 2023 Other Investments $ 6,182 Carrying Value N/A N/A Nonperforming Loans 253 (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 26,397 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.

There were no gains or losses included in earnings for the periods presented that are attributable to the change in realized gains (losses) relating to assets held at September 30, 2023 and 2022.

There were no gains or losses included in earnings for the periods presented that are attributable to the change in realized gains (losses) relating to assets held at September 30, 2023 and 2022. The tables below present the balances of assets measured at fair value on a nonrecurring basis at the dates shown below: September 30, 2023 Level 1 Level 2 Level 3 Total (dollars in thousands) Nonperforming loans $ — $ 21,934 $ 9,764 $ 31,698 Other real estate owned — 834 — 834 Total Assets $ — $ 22,768 $ 9,764 $ 32,532 December 31, 2022 Level 1 Level 2 Level 3 Total (dollars in thousands) Nonperforming loans $ — $ 23,140 $ 11,636 $ 34,776 Other real estate owned — 553 — 553 Total Assets $ — $ 23,693 $ 11,636 $ 35,329 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 for 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 has a current carrying value of $0.8 million as of September 30, 2023 and consists of seven residential real estate 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 cost 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 goodwill is provided in Note 13, “Goodwill.” There were no other assets or liabilities measured at fair value on a nonrecurring basis during the nine months ended September 30, 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 discussed 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 securities available for sale and held to maturity 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 and other equity investments, is considered a reasonable estimate of fair value. 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. Loans held for sale : The estimated fair value of loans held for sale is based on market bids obtained from potential buyers. 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 September 30, 2023 and December 31, 2022. See Note 6, “Commitments and Contingent Liabilities,” 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 type borrowings.

Goodwill Disclosure [Abstract]
Goodwill	GoodwillFASB ASC Topic 350-20, “Intangibles – Goodwill and Other” 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 at September 30, 2023 and December 31, 2022 was $363.7 million and $303.3 million, respectively. The $60.4 million increase in goodwill during the nine months ended September 30, 2023 is the result of the Centric acquisition. No impairment charges on goodwill or other intangible assets were incurred in 2023 or 2022. 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. As of September 30, 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.

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 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 Company 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 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, subject to regulatory approval, 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 rate 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 12 - "Derivatives".

Revenue Recognition and Deferred Revenue [Abstract]
Revenue from Contract with Customer	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 ASC Topic 606 - "Revenue from Contracts with Customers" ("Topic 606"). 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 $0.3 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 $3.1 million and $2.9 million in commission expense as of September 30, 2023 and 2022, respectively. 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 daily 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 the related gain or 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 Three Months Ended September 30, For the Nine Months Ended September 30, 2023 2022 2023 2022 (dollars in thousands) Noninterest Income In-scope of Topic 606: Trust income $ 2,949 $ 2,777 $ 7,967 $ 8,063 Service charges on deposit accounts 5,600 5,194 15,842 14,695 Insurance and retail brokerage commissions 2,305 2,048 7,171 6,806 Card-related interchange income 7,221 6,980 21,422 20,607 Gain on sale of other loans and assets 102 40 268 393 Other income 1,097 991 3,233 3,064 Noninterest Income (in-scope of Topic 606) 19,274 18,030 55,903 53,628 Noninterest Income (out-of-scope of Topic 606) 5,552 7,884 16,409 20,771 Total Noninterest Income $ 24,826 $ 25,914 $ 72,312 $ 74,399

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 September 30, 2023 and December 31, 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 using month-end balances of the loans for the period reported and are included in the table below based on their period-end allowance position. The increase in nonperforming loans is primarily a result of $22.0 million in loans acquired from Centric, offset by the removal of $6.4 million in accruing troubled debt restructurings ("TDR's"). The TDR's were eliminated as a result of our adoption of ASU 2022-02, Financial Instruments Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures ("ASU 2022-02"). This standard was adopted on January 1, 2023 and eliminates the accounting guidance for TDR's while enhancing disclosure requirements for loan modifications for borrowers experiencing financial difficulty.

Leases Lease Liability Maturity

Leases Lease Liability Maturity (Tables)	9 Months Ended

Leases [Abstract]
Lessee, Operating Leases [Text Block]	LeasesFirst Commonwealth has elected to apply certain practical expedients provided 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; and (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, including 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 unaudited Consolidated Statements of Condition classification of the Company’s right of use ("ROU") assets and lease liabilities, lease costs and other lease information. September 30, 2023 December 31, 2022 Balance sheet: Operating lease asset classified as premises and equipment $ 45,783 $ 40,747 Operating lease liability classified as other liabilities 50,155 45,149 For the Three Months Ended For the Nine Months Ended September 30, 2023 September 30, 2022 September 30, 2023 September 30, 2022 Income statement: Operating lease cost classified as occupancy and equipment expense $ 1,521 $ 1,259 $ 4,565 $ 3,727 Weighted average lease term, in years 13.37 14.10 Weighted average discount rate 3.51 % 3.28 % Operating cash flows $ 1,571 $ 1,245 In the above table, the increase in the ROU asset and lease liability at September 30, 2023 compared to December 31, 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 Federal Home Loan Bank ("FHLB") of Pittsburgh. This rate is consistent with a collateralized borrowing rate and is available for terms similar to the lease payment schedules. Future minimum payments for operating leases with initial or remaining terms of one year or more as of September 30, 2023 were as follows (dollars in thousands): For the twelve months ended: September 30, 2024 $ 5,847 September 30, 2025 5,621 September 30, 2026 5,160 September 30, 2027 4,909 September 30, 2028 4,672 Thereafter 37,922 Total future minimum lease payments 64,131 Less remaining imputed interest 13,976 Operating lease liability $ 50,155
