| Accounting Policies [Abstract] | |
| Summary of Significant Accounting Policies | NOTE 1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Basis of presentation — The accompanying unaudited interim financial statements of Wesbanco, Inc. and its consolidated subsidiaries (“Wesbanco” or the "Company") have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim financial information and the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements and should be read in conjunction with our Annual Report on Form 10-K for the year ended December 31, 2025. Wesbanco’s interim financial statements have been prepared following the significant accounting policies disclosed in Note 1 of the Notes to the Consolidated Financial Statements of its 2025 Annual Report on Form 10-K filed with the Securities and Exchange Commission ("SEC"), as well as with the policy changes indicated below. In the opinion of management, the accompanying interim financial information reflects all adjustments, including normal recurring adjustments, necessary to present fairly Wesbanco’s financial position and results of operations for each of the interim periods presented. Results of operations for interim periods are not necessarily indicative of the results of operations that may be expected for a full year. Recent accounting pronouncements—The Financial Accounting Standards Board (“FASB”) issued Accounting Standards Updates (“ASU”) as noted below. ASU 2025‑12 — Codification Improvements In December 2025, the FASB issued ASU 2025‑12, “Codification Improvements.” This Update is part of the Board’s ongoing effort to address technical corrections, clarifications, and minor improvements across the FASB Accounting Standards Codification. These improvements refine the application of existing guidance, resolve inconsistencies, and improve the usability of the Codification without introducing significant changes to accounting practice or requiring substantial implementation effort. The amendments are not expected to significantly affect current practice. However, updates will be reviewed for any potential effects on accounting policies or disclosure processes. The amendments in this Update are effective for all entities for annual periods beginning after December 15, 2026, including interim periods within those annual periods. Early adoption is permitted. The adoption of this pronouncement is not expected to have a material impact on the Consolidated Financial Statements. ASU 2025‑11 — Interim Reporting (Topic 270): Narrow‑Scope Improvements In December 2025, the FASB issued ASU 2025‑11, “Interim Reporting (Topic 270): Narrow‑Scope Improvements.” The amendments are intended to improve the navigability and clarity of interim reporting requirements under Topic 270. The Update clarifies when Topic 270 applies, adds a comprehensive list of required interim disclosures, and introduces a disclosure principle requiring entities to disclose events occurring after the most recent annual period that have a material impact on the entity. The Update does not expand or reduce overall interim disclosure requirements but instead compiles and organizes them to improve consistency and comparability. The guidance also clarifies form‑and‑content expectations for interim financial statements, including the use of condensed statements, and aligns GAAP with prior SEC requirements regarding material events. The amendments are effective for interim reporting periods beginning after December 15, 2027, for public business entities and one year later for all other entities. Early adoption is permitted, with prospective or retrospective application available. The adoption of this pronouncement is not expected to have a material impact on the Consolidated Financial Statements. ASU 2025‑10 — Government Grants (Topic 832): Accounting for Government Grants Received by Business Entities In December 2025, the FASB issued ASU 2025‑10, “Government Grants (Topic 832): Accounting for Government Grants Received by Business Entities.” The amendments establish authoritative U.S. GAAP for the recognition, measurement, and presentation of government grants received by business entities. Historically, in the absence of explicit guidance, entities analogized to IAS 20 or ASC 958‑605, resulting in diversity in practice. ASU 2025‑10 adopts a model largely based on IAS 20, with revisions for U.S. GAAP. Under this Update, a government grant is defined as a transfer of a monetary or tangible nonmonetary asset from a governmental body in a non‑exchange transaction. The guidance excludes transactions such as income‑tax credits under Topic 740, below‑market interest rate loans, government guarantees, contributions from nongovernmental sources, and transfers of intangible assets or services. Recognition is required when it is probable that the entity will comply with grant conditions and the grant will be received. Grants related to assets are recognized as the related costs are incurred; grants related to income are recognized as the related expenses are incurred. The amendments are effective for public business entities for annual periods beginning after December 15, 2028, and one year later for all other entities. Early adoption is permitted. The adoption of this pronouncement is not expected to have a material impact on the Consolidated Financial Statements. ASU 2025-09 — Derivatives and Hedging (Topic 815): Hedging Accounting Improvements In November 2025, the FASB issued ASU 2025‑09, “Derivatives and Hedging (Topic 815): Hedge Accounting Improvements.” The amendments in this Update enhance and clarify several aspects of hedge accounting to better align financial reporting with the economics of an entity’s risk‑management activities. The guidance addresses key areas including similar risk assessments for groups of forecasted transactions, hedging of forecasted interest payments on “choose‑your‑rate” debt instruments, hedging of nonfinancial forecasted transactions, use of net written options as hedging instruments, and the treatment of foreign currency‑denominated debt in certain dual hedging strategies. The amendments allow a broader set of forecasted transactions to qualify for hedge accounting by focusing on “similar risk exposure” rather than requiring identical risk characteristics. Entities must evaluate this criterion at hedge inception and on an ongoing basis, using qualitative assessments where appropriate. The amendments in this Update are effective for public business entities for annual periods beginning after December 15, 2026, and one year later for all other entities. Early adoption is permitted. Adoption is prospective, with transition provisions available to facilitate migration of existing hedging relationships. The adoption of this pronouncement is not expected to have a material impact on the Consolidated Financial Statements. ASU 2025-08 — Financial Instruments—Credit Losses (Topic 326): Purchased Loans In November 2025, the FASB issued ASU 2025‑08, “Financial Instruments—Credit Losses (Topic 326): Purchased Loans.” The amendments in this update make significant changes to the accounting for certain acquired seasoned loans subject to CECL. The Board decided not to change the existing models for originated assets, purchased credit deteriorated ("PCD") assets or other acquired assets. Under the ASU, the initial allowance for credit losses recorded upon the acquisition of loans in scope is recognized as an adjustment to the amortized cost basis of the loan–similar to the PCD model. For these loans, the “day-one” credit loss estimate does not impact earnings immediately but rather is amortized over time as an adjustment to interest income. Subsequent changes in the allowance for credit losses are reported in earnings within credit loss expense. The amendments in this Update are effective for all entities for fiscal years beginning after December 15, 2026, including interim periods within those fiscal years, and are to be applied prospectively to loans acquired on or after the date of adoption. Early adoption is permitted. The adoption of this pronouncement is not expected to have a material impact on the Consolidated Financial Statements. ASU 2025-07 — Derivatives and Hedging (Topic 815) and Revenue from Contracts with Customers (Topic 606) In September 2025, the FASB issued ASU 2025-07, “Derivatives and Hedging (Topic 815) and Revenue from Contracts with Customers (Topic 606).” The amendments in this Update apply to all entities that enter into non exchange-traded contracts with underlyings based on operations or activities specific to one of the parties to the contract. The amendments in this Update exclude from derivative accounting non exchange-traded contracts with underlyings that are based on operations or activities specific to one of the parties to the contract. However, this scope exception does not apply to (1) variables based on a market rate, market price, or market index, (2) variables based on the price or performance of a financial asset or financial liability of one of the parties to the contract, (3) contracts (or features) involving the issuer’s own equity that are evaluated under the guidance in Subtopic 815-40, Derivatives and Hedging—Contracts in Entity’s Own Equity, and (4) call options and put options on debt instruments. The amendments in this Update are effective for all entities for annual reporting periods beginning after December 15, 2026, and interim reporting periods within those annual reporting periods. Early adoption is permitted. The adoption of this pronouncement is not expected to have a material impact on the Consolidated Financial Statements. ASU 2025-05 — Financial Instruments—Credit Losses (Topic 326) In July 2025, the FASB issued ASU 2025-05, “Financial Instruments – Credit Losses (Topic 326).” The amendments provide (1) all entities with a practical expedient when estimating expected credit losses for current accounts receivable and current contract assets arising from transactions accounted for under Topic 606 and (2) entities other than public business entities with an accounting policy election for those same asset classes. The amendments will be effective for annual reporting periods beginning after December 15, 2025, and interim reporting periods within those annual reporting periods. The Company adopted ASU 2025‑05 effective January 1, 2026 and elected the practical expedient for in-scope current accounts receivable and contract assets. Loans and other financial assets measured at amortized cost are not within the scope of this guidance. Therefore, the adoption of this pronouncement does not have a material impact on the Consolidated Financial Statements, including the allowance for credit losses. ASU 2025-01 & 2024-03 — Income Statement — Reporting Comprehensive Income –Expense Disaggregation Disclosures (Subtopic 220-40) In November 2024, the FASB issued ASU 2024-03, “Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures.” The amendments in this Update improve financial reporting by requiring that public business entities disclose additional information about specific expense categories in the notes to financial statements at interim and annual reporting periods. This information is generally not presented in the financial statements today. For Wesbanco, the amendments in this Update are effective for annual reporting periods beginning after December 15, 2026, and interim reporting periods beginning after December 15, 2027. Early adoption is permitted. In January 2025, the FASB issued ASU 2025-01, “Income Statement — Reporting Comprehensive Income – Expense Disaggregation Disclosures (Subtopic 220-40).” The amendment in this Update amends the effective date of ASU 2024-03 to clarify that all public business entities are required to adopt the guidance in annual reporting periods beginning after December 15, 2026, and interim periods within annual reporting periods beginning after December 15, 2027. Early adoption is permitted. The adoption of these pronouncements is not expected to have a material impact on the Consolidated Financial Statements, but is expected to result in additional disclosures and potential changes to the line items on the Consolidated Statement of Income. |

| Earnings Per Common Share | NOTE 2. EARNINGS PER COMMON SHARE Earnings per common share are calculated as follows:
As of March 31, 2026 and 2025, 237,001 and 325,701 options to purchase shares were not included in the diluted share computation for the three months ended March 31, 2026 and 2025, respectively, because the exercise price was greater than the average market price of a common share, and, therefore, the effect would be antidilutive. As of March 31, 2026 and 2025, 24,000 shares were estimated to be awarded under the 2025 and 2024 total shareholder return ("TSR") plans and were included in the diluted calculation as stock performance targets had been met. In addition, 106,119 shares of performance-based restricted stock were included in the diluted calculation as of March 31, 2026 because the performance criteria was met. Similarly, at March 31, 2025, 92,813 shares were estimated to be awarded and were included in the diluted calculation. As previously disclosed, 28,738,104 shares were issued as merger consideration to complete the PFC acquisition on February 28, 2025. To accomplish this, Wesbanco used 8,421,434 shares of Treasury stock and 20,316,670 newly-issued common shares. These shares are included in the average shares outstanding beginning on those dates mentioned. |

| Securities | NOTE 3. SECURITIES The following table presents the fair value and amortized cost of available-for-sale and held-to-maturity debt securities:
(1) Total held-to-maturity debt securities are presented on the balance sheet net of their allowance for credit losses totaling $0.2 million at March 31, 2026 and December 31, 2025.
At March 31, 2026 and December 31, 2025, there were no holdings of any one issuer, other than U.S. government sponsored entities and its agencies, in an amount greater than 10% of Wesbanco’s shareholders’ equity. Equity securities, of which $27.6 million and $28.2 million at March 31, 2026 and December 31, 2025, respectively, consist of investments in various mutual funds held in grantor trusts formed in connection with the Company’s deferred compensation plan, are recorded at fair value, and totaled $30.3 million and $30.8 million at March 31, 2026 and December 31, 2025, respectively. The following table presents the amortized cost and fair value of available-for-sale and held-to-maturity debt securities by contractual maturity date at March 31, 2026. Actual maturities will differ from contractual maturities because borrowers may have the right to call or prepay debt obligations with or without prepayment penalties. Mortgage-backed securities and collateralized mortgage obligations are classified in the table below based on their contractual maturity date; however, regular principal payments and prepayments of principal are received on a monthly basis.
Securities with an aggregate carrying value of $2.8 billion at March 31, 2026 and December 31, 2025, respectively, were pledged as security for public and trust funds, and securities sold under agreements to repurchase. There were no security sales that occurred in the three months ended March 31, 2026. Proceeds from the sale of available-for-sale securities for the three months ended March 31, 2025 totaled $873.8 million. Net unrealized losses on available-for-sale securities included in accumulated other comprehensive income, net of tax, as of March 31, 2026 and December 31, 2025 were $153.5 million and $139.5 million, respectively. The following table presents the gross realized gains and losses on sales and calls of available-for-sale and held-to-maturity debt securities, as well as gains and losses on equity securities from both sales and market adjustments, for the three months ended March 31, 2026 and 2025, respectively. All gains and losses presented in the table below are included in the net securities gains (losses) line item of the consolidated income statement. For those equity securities relating to the key officer and director deferred compensation plan, the corresponding change in the obligation to the participant is recognized in employee benefits expense.
The corporate and municipal bonds in Wesbanco’s held-to-maturity debt portfolio are analyzed quarterly to determine if an allowance for current expected credit losses is warranted. Wesbanco uses a database of historical financials of all corporate and municipal issuers and actual historic default and recovery rates on rated and non-rated transactions to estimate expected credit losses on an individual security basis. The expected credit losses are adjusted quarterly and are recorded in an allowance for expected credit losses on the balance sheet, which is deducted from the amortized cost basis of the held-to-maturity portfolio as a contra asset. The losses are recorded on the consolidated income statement in the provision for credit losses. Accrued interest receivable on held-to-maturity securities, which was $8.0 million and $8.2 million as of March 31, 2026 and December 31, 2025, respectively, is excluded from the estimate of credit losses. Held-to-maturity investments in U.S. Government sponsored entities and agencies as well as mortgage-backed securities and collateralized mortgage obligations, which are all either issued by a direct governmental entity or a government-sponsored entity, have no historical evidence supporting expected credit losses; therefore, Wesbanco has estimated these losses at zero, and will monitor this assumption in the future for any economic or governmental policies that could affect this assumption. The following table provides a roll-forward of the allowance for credit losses on held-to-maturity securities for the three months ended March 31, 2026 and 2025:
(1) The total provision for credit losses on held-to-maturity securities is reported in the consolidated statements of income in the provision for credit losses line item, which also includes the provision for credit losses - loans and loan commitments. For more information on the provision relating to loans and loan commitments, please see Note 4, "Loans and the Allowance for Credit Losses."
The following tables provide information on unrealized losses on available-for-sale debt securities that have been in an unrealized loss position for less than twelve months and twelve months or more, for which an allowance for credit losses has not been recorded, as of March 31, 2026 and December 31, 2025, respectively:
Unrealized losses on debt securities in the table above represent temporary fluctuations resulting from changes in market rates in relation to fixed yields. Unrealized losses in the available-for-sale portfolio are accounted for as an adjustment, net of taxes, to other comprehensive income in shareholders’ equity. Wesbanco does not believe the securities presented above are impaired due to reasons of credit quality, as substantially all debt securities are rated above investment grade and all are paying principal and interest according to their contractual terms. Wesbanco does not intend to sell, nor is it more likely than not that it will be required to sell, loss position securities prior to recovery of their cost; therefore, management believes the unrealized losses detailed above do not require an allowance for credit losses relating to these securities to be recognized. Securities that do not have readily determinable fair values and for which Wesbanco does not exercise significant influence are carried at cost. Cost method investments consist primarily of FHLB stock totaling $50.1 million and $58.5 million at March 31, 2026 and December 31, 2025, respectively, and are included in other assets in the Consolidated Balance Sheets. Cost method investments are evaluated for impairment whenever events or circumstances suggest that their carrying value may not be recoverable.

| Loans and the Allowance for Credit Losses | NOTE 4. LOANS AND THE ALLOWANCE FOR CREDIT LOSSES The recorded investment in loans is presented in the Consolidated Balance Sheets net of deferred loan fees and costs, and discounts on purchased loans. Net deferred loan costs were $14.8 million and $13.9 million at March 31, 2026 and December 31, 2025, respectively. The unaccreted discount on purchased loans from acquisitions was $288.8 million at March 31, 2026 and $302.4 million at December 31, 2025.
Allowance for Credit Losses The allowance for credit losses under the current expected credit losses methodology is calculated on non-PCD loans utilizing a probability of default ("PD") and loss given default ("LGD") approach, which is then discounted to net present value. PD is the probability the asset will default within a given time frame and LGD is the percentage of the asset not expected to be collected due to default. The primary macroeconomic drivers of the quantitative model include forecasts of national unemployment and interest rates, as well as modeling adjustments for changes in prepayment speeds, portfolio mix, concentrations and loan growth. At March 31, 2026, the primary drivers of the change in the allowance model calculation from December 31, 2025 were macroeconomic variables, prepayment speeds, qualitative factors for credit quality, changes in risk grading, increases to specific reserves on individually-evaluated loans and an increase in net charge-offs. The forecast was based upon a probability weighted approach which is designed to incorporate loss projections from a baseline, upside and downside economy. Due to the nonlinearity of credit losses to the economy, the asymmetry is best captured by evaluating multiple economic scenarios through a probability weighted approach. At quarter-end, national unemployment was projected to be 4.8%, and subsequently increase to an average of 5.2% over the remainder of the forecast period. In addition to the quantitative and qualitative changes noted above, the allowance is reflective of $7.6 million in net charge-offs recorded during the first three months of 2026. Accrued interest receivable for loans was $85.2 million and $87.8 million at March 31, 2026 and December 31, 2025, respectively. Wesbanco made an accounting policy election to exclude accrued interest from the measurement of the allowance for credit losses because the Company has a policy in place to reverse or write-off accrued interest when loans are placed on non-accrual. However, due to their unique nature, Wesbanco does have a $0.1 million reserve on the accrued interest related to individually-evaluated loans at March 31, 2026.
The following tables summarize changes in the allowance for credit losses applicable to each category of the loan portfolio:
(1) The total provision for credit losses - loans and loan commitments is reported in the consolidated statements of income in the provision for credit losses line item, which also includes the provision for credit losses on held-to-maturity securities. For more information on the provision relating to held-to-maturity securities, please see Note 3, "Securities." (2) The charge-offs on the acquired PFC loan portfolio prior to the acquisition were $22.7 million.
The following tables present the allowance for credit losses and recorded investments in loans by category, as of each period-end:
(1) For additional detail relating to loan commitments, see Note 11, "Commitments and Contingent Liabilities." Commercial Loan Risk Grades Commercial loan risk grades are determined based on an evaluation of the relevant characteristics of each loan, assigned at inception and adjusted thereafter at any time to reflect changes in the risk profile throughout the life of each loan. The primary factors used to determine the risk grade are the sufficiency, reliability and sustainability of the primary source of repayment and overall financial strength of the borrower. The rating system more heavily weights the debt service coverage, leverage and loan to value factors to derive the risk grade. Other factors that are considered at a lesser weighting include management, industry or property type risks, payment history, collateral or guarantees. Commercial real estate – land and construction consists of loans to finance investments in vacant land, land development, construction of residential housing, and construction of commercial buildings. Commercial real estate – improved property consists of loans for the purchase or refinance of all types of improved owner-occupied and investment properties. Factors that are considered in assigning the risk grade vary depending on the type of property financed. The risk grade assigned to construction and development loans is based on the overall viability of the project, the experience and financial capacity of the developer or builder to successfully complete the project, project specific and market absorption rates and comparable property values, and the amount of pre-sales for residential housing construction or pre-leases for commercial investment property. The risk grade assigned to commercial investment property loans is based primarily on the adequacy of the net operating income generated by the property to service the debt (“debt service coverage”), the loan to appraised value, the type, quality, industry and mix of tenants, and the terms of leases. The risk grade assigned to owner-occupied commercial real estate is based primarily on global debt service coverage and the leverage of the business, but may also consider the industry in which the business operates, the business’ specific competitive advantages or disadvantages, collateral margins and the quality and experience of management. Commercial and industrial (“C&I”) loans consist of revolving lines of credit to finance accounts receivable, inventory and other general business purposes; term loans to finance fixed assets other than real estate, and letters of credit to support trade, insurance or governmental requirements for a variety of businesses. Most C&I borrowers are privately-held companies with annual sales up to $100 million. Primary factors that are considered in risk rating C&I loans include debt service coverage and leverage. Other factors including operating trends, collateral coverage along with management experience are also considered. Pass loans are those that exhibit a history of positive financial results that are at least comparable to the average for their industry or type of real estate. The primary source of repayment is acceptable and these loans are expected to perform satisfactorily during most economic cycles. Pass loans typically have no significant external factors that are expected to adversely affect these borrowers more than others in the same industry or property type. Any minor unfavorable characteristics of these loans are outweighed or mitigated by other positive factors including but not limited to adequate secondary or tertiary sources of repayment, including guarantees. Criticized loans, considered as compromised, have potential weaknesses that deserve management's close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the asset or in the bank's credit position at some future date. Criticized loans are not adversely classified by the banking regulators and do not expose the bank to sufficient risk to warrant adverse classification. Classified loans, considered as substandard and doubtful, are equivalent to the classifications used by banking regulators. Substandard loans are inadequately protected by the current sound worth and paying capacity of the obligor or of the collateral pledged, if any. Loans so classified must have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt. They are characterized by the distinct possibility that the bank will sustain some loss if the deficiencies are not corrected. These loans may or may not be reported as non-accrual. Doubtful loans have all the weaknesses inherent in those classified substandard, with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of currently known facts, conditions, and values, highly questionable and improbable. These loans are reported as non-accrual. The following tables summarize commercial loans by their assigned risk grade:
Residential real estate, home equity and consumer loans are not assigned internal risk grades other than as required by regulatory guidelines that are based primarily on the age of past due loans. Wesbanco primarily evaluates the credit quality of residential real estate, home equity and consumer loans based on repayment performance and historical loss rates. The aggregate amount of residential real estate, home equity and consumer loans classified as substandard in accordance with regulatory guidelines was $54.0 million at March 31, 2026 and $61.4 million at December 31, 2025, of which $8.3 million and $16.5 million were accruing, for each period, respectively. These loans are not included in the tables above. In addition, $72.1 million and $57.1 million of unfunded commercial loan commitments are also not included in the tables above at March 31, 2026 and December 31, 2025, respectively. Past Due and Nonperforming Loans The following tables summarize the age analysis of all categories of loans:
The following tables summarize nonperforming loans:
(1) The difference between the unpaid principal balance and the recorded investment generally reflects amounts that have been previously charged-off, fair market value adjustments on acquired nonperforming loans and capitalized loan origination fees and costs.
The following table presents the recorded investment in non-accrual loans:
(1) At March 31, 2026, there were seventeen borrowers with a loan balance greater than $1.0 million, which totaled $87.7 million, as compared to eleven borrowers with loan balances greater than $1.0 million totaling $35.5 million at December 31, 2025. Total non-accrual loans may include loans that are also restructured for borrowers experiencing financial difficulty. Such loans are also set forth in the following tables.
Financial Difficulty Modifications
Tables in the following section exclude the financial effects of modifications for loans that were paid off or are otherwise no longer in the loan portfolio as of period end. The following table displays the details of portfolio loans that were modified during the three months ended March 31, 2026 and 2025 presented by loan category:
Unfunded loan commitments on financial difficulty modifications ("FDMs") totaled $0.4 million for loans modified during the three months ended March 31, 2026 and $1.0 million for loans modified during the three months ended March 31, 2025. These commitments are not included in the tables above.
The following table summarizes the financial impacts of loan modifications and payment deferrals made to portfolio loans during the three months ended March 31, 2026 and 2025, presented by loan category:
The following table summarizes loans with FDMs which defaulted (defined as 90 days past due) within 12 months of the loan being modified during the three months ended March 31, 2026 and 2025. Modified loans, including those that have defaulted, are already included in the allowance for credit losses through the various methodologies used to estimate the allowance. As such, no modification to the allowance is recorded specifically due to a modified loan subsequently defaulting.
The following tables present an aging analysis of portfolio loans by loan category that were modified during the twelve months prior to March 31, 2026 and March 31, 2025.

| Investments in Limited Partnerships | NOTE 5. INVESTMENTS IN LIMITED PARTNERSHIPS Wesbanco is a limited partner in several tax-advantaged limited partnerships whose purpose is to invest in approved low-income housing investment tax credit projects. These investments are accounted for using the proportional amortization method of accounting and are included in other assets in the Consolidated Balance Sheets. The limited partnerships are considered to be VIEs as they generally do not have equity investors with voting rights or have equity investors that do not provide sufficient financial resources to support their activities. The VIEs have not been consolidated because Wesbanco is not considered the primary beneficiary. All of Wesbanco’s investments in limited partnerships are privately held, and their market values are not readily available. As of March 31, 2026 and December 31, 2025, Wesbanco had $80.7 million and $83.7 million, respectively, invested in these partnerships. Wesbanco also recognizes the unconditional unfunded equity commitments of $33.8 million and $37.5 million at March 31, 2026 and December 31, 2025, respectively, within other liabilities on the Consolidated Balance Sheets. Wesbanco classifies the amortization of the investment as a component of income tax expense (benefit) and proportionally amortizes the investment over the tax credit period. The for the three months ended March 31, 2026 and 2025 was $3.1 million and $1.9 million, respectively. Tax benefits attributed to these partnerships include low-income housing and historic tax credits, which are projected to total $11.6 million for 2026, and totaled $9.9 million for 2025, which are also included in income tax expense. Wesbanco is also a limited partner in three other limited partnerships as of March 31, 2026. These provide seed money and capital to startup companies, and financing to low-income housing projects. As of March 31, 2026 and December 31, 2025, Wesbanco had $4.3 million and $4.0 million, respectively, invested in these partnerships, which are recorded in other assets using the equity method. Wesbanco included in operations under the equity method of accounting its share of the partnerships’ net income for the three months ended March 31, 2026 and 2025 of $27 thousand and $5 thousand, respectively. The following table presents the scheduled equity commitments to be paid to the limited partnerships over the next five years and in the aggregate thereafter as of March 31, 2026:

| Derivatives and Hedging Activities | NOTE 6. DERIVATIVES AND HEDGING ACTIVITIES Risk Management Objective of Using Derivatives Wesbanco is exposed to certain risks arising from both its business operations and economic conditions. Wesbanco principally manages its exposures to a wide variety of business and operational risks through management of its core business activities. Wesbanco manages economic risks, including interest rate, liquidity, and credit risk, primarily by managing the amount, sources, and duration of its assets and liabilities. Wesbanco’s existing interest rate derivatives result from a service provided to certain qualifying customers and, therefore, are not used to manage interest rate risk in Wesbanco’s assets or liabilities. Wesbanco manages a matched book with respect to its derivative instruments in order to minimize its net risk exposure resulting from such transactions. A matched book is when the assets and liabilities of Wesbanco Bank, Inc., Wesbanco's banking subsidiary (the "Bank") are equally distributed but also have similar maturities. Loan Swaps Wesbanco executes interest rate swaps and interest rate caps with commercial banking customers to facilitate their respective risk management strategies. Those interest rate swaps and caps are economically hedged by offsetting interest rate swaps and caps that Wesbanco executes with a third party, such that Wesbanco minimizes its net risk exposure resulting from such transactions. As the interest rate swaps and caps associated with this program do not meet the hedge accounting requirements of ASC 815, changes in the fair value of both the customer swaps and caps and the offsetting third-party swaps and caps are recognized directly in earnings. As of March 31, 2026 and December 31, 2025, Wesbanco had 373 and 368 customer interest rate swaps and caps, respectively, with an aggregate notional amount of $2.6 billion related to this program. Wesbanco recognized income for the related swap and cap fees of $1.2 million and $2.0 million for the three months ended March 31, 2026 and 2025, respectively. Risk participation agreements are entered into as financial guarantees of performance on interest rate swap derivatives. The purchased asset or sold liability allows Wesbanco to participate-in (fee received) or participate-out (fee paid) the risk associated with certain derivative positions executed by the borrower of the lead bank in a loan syndication. As of March 31, 2026 and December 31, 2025, Wesbanco had 25 and 26 risk participation-in agreements with an aggregate notional amount of $241.6 million and $271.8 million, respectively. As of March 31, 2026 and December 31, 2025, Wesbanco had nine risk participation-out agreements with an aggregate notional amount of $89.3 million and $89.5 million, respectively. Mortgage Loans Held for Sale and Interest Rate Lock Commitments Certain residential mortgage loans are originated for sale in the secondary mortgage loan market. These loans are classified as held for sale and carried at fair value as Wesbanco has elected the fair value option. Fair value is determined based on rates obtained from the secondary market for loans with similar characteristics. Wesbanco sells loans to the secondary market on either a mandatory or best efforts basis. The loans sold on a mandatory basis are not committed to an investor until the loan is closed with the borrower. Wesbanco enters into forward to be announced (“TBA”) contracts to manage the interest rate risk between the lock commitment and the closing of the loan. The total balance of forward TBA contracts entered into was $92.1 million and $91.0 million at March 31, 2026 and December 31, 2025, respectively. The loans sold on a best efforts basis are committed to an investor simultaneous to the interest rate commitment with the borrower, and as a result, the Company does not enter into a separate forward TBA contract to offset the fair value risk as the investor accepts such risk in exchange for paying a lower premium on sale. Fair Values of Derivative Instruments on the Balance Sheet All derivatives are carried on the consolidated balance sheet at fair value. Derivative assets are classified in the consolidated balance sheet under other assets, and derivative liabilities are classified in the consolidated balance sheet under other liabilities. Changes in fair value are recognized in earnings. None of Wesbanco’s derivatives are designated in a qualifying hedging relationship under ASC 815. The table below presents the fair value of Wesbanco’s derivative financial instruments as well as their classification on the Balance Sheet as of March 31, 2026 and December 31, 2025:
Effect of Derivative Instruments on the Income Statement The table below presents the change in the fair value of the Company’s derivative financial instruments reflected within non-interest income on the consolidated income statement for the three months ended March 31, 2026 and 2025, respectively.
Credit-risk-related Contingent Features Wesbanco has agreements with its derivative counterparties that contain a provision, which provides that if Wesbanco defaults on any of its indebtedness, including default where repayment of the indebtedness has not been accelerated by the lender, then Wesbanco could also be declared in default on its derivative obligations. Wesbanco also has agreements with certain of its derivative counterparties that contain a provision where if Wesbanco fails to maintain its status as either a “well” or “adequately-capitalized” institution, then the counterparty could terminate the derivative positions and Wesbanco would be required to settle its obligations under the agreements. Dependent upon the net present value of the underlying swaps, Wesbanco has minimum collateral posting thresholds with certain of its derivative counterparties. Wesbanco was holding net cash collateral from various derivative counterparties totaling $4.9 million within interest bearing deposit accounts as of March 31, 2026, while Wesbanco had posted net cash collateral with a market value of $16.0 million as of December 31, 2025. If Wesbanco had breached any of these provisions at March 31, 2026, it could have been required to settle its obligations under the agreements at the termination value and would have been required to pay any additional amounts due in excess of amounts previously posted as collateral with the respective counterparties. |

| Fair Value Measurement | NOTE 8. FAIR VALUE MEASUREMENT Fair value estimates are based on quoted market prices, if available, quoted market prices of similar assets or liabilities, or the present value of expected future cash flows and other valuation techniques. These valuations are significantly affected by discount rates, cash flow assumptions, and risk assumptions used. Therefore, fair value estimates may not be substantiated by comparison to independent markets and are not intended to reflect the proceeds that may be realizable in an immediate settlement of the instruments. Fair value is determined at one point in time and is not representative of future value. These amounts do not reflect the total value of a going concern organization. Management does not have the intention to dispose of a significant portion of its assets and liabilities, and therefore the unrealized gains or losses should not be interpreted as a forecast of future earnings and cash flows. The following is a discussion of assets and liabilities measured at fair value on a recurring basis and valuation techniques applied: Investment securities: The fair value of investment securities which are measured on a recurring basis are determined primarily by obtaining quoted prices on nationally recognized securities exchanges or matrix pricing, which is a mathematical technique used widely in the industry to value debt securities without relying exclusively on quoted prices for the specific securities but rather by relying on the securities’ relationship to other similar securities. These securities are classified within level 1 or 2 in the fair value hierarchy. Positions that are not traded in active markets for which valuations are generated using assumptions not observable in the market or management’s best estimate are classified within level 3 of the fair value hierarchy. This includes certain specific municipal debt issues for which the credit quality and discount rate must be estimated. Loans held for sale: Loans held for sale are carried, in aggregate, at fair value as Wesbanco previously elected the fair value option. The use of a valuation model using quoted prices of similar instruments are significant inputs in arriving at the fair value and therefore loans held for sale are classified within level 2 of the fair value hierarchy. Derivatives: Wesbanco enters into interest rate swap agreements with qualifying commercial customers to meet their financing, interest rate and other risk management needs. These agreements provide the customer the ability to convert from variable to fixed interest rates. The credit risk associated with derivatives executed with customers is essentially the same as that involved in extending loans and is subject to normal credit policies and monitoring. Those interest rate swaps are economically hedged by offsetting interest rate swaps that Wesbanco executes with derivative counterparties in order to offset its exposure on the fixed components of the customer interest rate swap agreements. The interest rate swap agreement with the loan customer and with the counterparty is reported at fair value in other assets and other liabilities on the consolidated balance sheet with any resulting gain or loss recorded in current period earnings as other income and other expense. Wesbanco enters into forward TBA contracts to manage the interest rate risk between the loan commitments to the customer and the closing of the loan for loans that will be sold on a mandatory basis to secondary market investors. The forward TBA contract is reported at fair value in other assets and other liabilities on the consolidated balance sheet with any resulting gain or loss recorded in current period’s earnings as mortgage banking income. Wesbanco determines the fair value for derivatives using widely accepted valuation techniques including discounted cash flow analysis on the expected cash flows of each derivative. This analysis reflects contractual terms of the derivative, including the period to maturity, and uses observable market-based inputs, including interest rate curves and implied volatilities. Wesbanco incorporates credit valuation adjustments to appropriately reflect both its own non-performance risk and the respective counterparty’s non-performance risk in the fair value measurements, and therefore both the derivative asset and derivative liability are classified within level 2 of the fair value hierarchy. We may be required from time to time to measure certain assets and liabilities at fair value on a nonrecurring basis in accordance with GAAP. These adjustments to fair value usually result from the application of lower of cost or market accounting or write-downs of individual assets and liabilities. Collateral dependent loans: Collateral dependent loans are carried at the amortized cost basis less the specific allowance calculated under the Current Expected Credit Losses Accounting Standard. Collateral dependent loans are calculated using a cost basis approach or collateral value approach, and therefore are classified within level 3 of the fair value hierarchy. Other real estate owned and repossessed assets: Other real estate owned and repossessed assets are carried at the lower of the investment in the assets or the fair value of the assets less estimated selling costs. The use of independent appraisals and management’s best judgment are significant inputs in arriving at the fair value measure of the underlying collateral, and therefore other real estate owned and repossessed assets are classified within level 3 of the fair value hierarchy. The fair value amounts presented in the tables below are intended to permit reconciliation of the fair value hierarchy to the amounts presented in the statement of financial position. The following tables set forth Wesbanco’s financial assets and liabilities that were accounted for at fair value on a recurring and nonrecurring basis by level within the fair value hierarchy as of March 31, 2026 and December 31, 2025:
Wesbanco’s policy is to recognize transfers between levels as of the actual date of the event or change in circumstances that caused the transfer. There were no transfers between level 1, 2 or 3 for the three months ended March 31, 2026 or for the year ended December 31, 2025. The following table presents additional quantitative information about assets measured at fair value on a nonrecurring basis and for which Wesbanco has utilized level 3 inputs to determine fair value:
(1) Fair value is generally determined through independent appraisals of the underlying collateral, which generally include various level 3 inputs, which are not identifiable. (2) Appraisals may be adjusted by management for qualitative factors such as economic conditions and estimated liquidation expenses. The range and weighted average of appraisal adjustments and liquidation expense are presented as a percent of the appraisal. (3) Includes estimated liquidation expenses and numerous dissimilar qualitative adjustments by management, which are not identifiable. The estimated fair values of Wesbanco’s financial instruments are summarized below:
The following methods and assumptions were used to measure the fair value of financial instruments recorded at cost on Wesbanco’s consolidated balance sheets: Cash and due from banks: The carrying amount for cash and due from banks is a reasonable estimate of fair value. Held-to-maturity debt securities: Fair values for debt securities held-to-maturity are determined in the same manner as investment securities, which are described above. The carrying value is net of the allowance for credit losses on held-to-maturity debt securities. Net loans: Fair values for loans are estimated in a valuation model using a discounted cash flow methodology. The discount rates take into account interest rates currently being offered to customers for loans with similar terms, the credit risk associated with the loan and other market factors, including liquidity. Wesbanco believes the discount rates are consistent with transactions occurring in the marketplace for both performing and distressed loan types. The carrying value is net of the allowance for loan losses and other associated premiums and discounts. Due to the significant judgment involved in evaluating credit quality, loans are classified within level 3 of the fair value hierarchy. Accrued interest receivable: The carrying amount of accrued interest receivable approximates its fair value. Deposits: The carrying amount is considered a reasonable estimate of fair value for demand, savings and other variable rate deposit accounts. The fair value of fixed maturity certificates of deposit is estimated by a discounted cash flow method using rates currently offered for deposits of similar remaining maturities. Federal Home Loan Bank borrowings: The fair value of FHLB borrowings is based on rates currently available to Wesbanco for borrowings with similar terms and remaining maturities. Other borrowings: The carrying amount of federal funds purchased and overnight sweep accounts generally approximate fair value. Other repurchase agreements are based on quoted market prices if available. If market prices are not available, for certain fixed and adjustable rate repurchase agreements, then quoted market prices of similar instruments are used. Subordinated debt and junior subordinated debt: The fair value of subordinated debt is determined primarily by obtaining quoted prices on nationally recognized securities exchanges or matrix pricing, which is a mathematical technique used widely in the industry to value debt securities without relying exclusively on quoted prices for the specific securities but rather by relying on the securities’ relationship to other similar securities. These securities are classified within level 2 in the fair value hierarchy. Due to the pooled nature of junior subordinated debt owed to unconsolidated subsidiary trusts, which are not actively traded, estimated fair value is determined by using comparable corporate bond indices and swap rates from the financial services sector and factoring in the applicable credit spreads and optional early redemption provisions. Accrued interest payable: The carrying amount of accrued interest payable approximates its fair value. Off-balance sheet financial instruments: Off-balance sheet financial instruments consist of commitments to extend credit, including letters of credit. Fair values for commitments to extend credit are estimated using the fees currently charged to enter into similar agreements, taking into account the remaining terms of the agreements and the present credit standing of the counterparties. The estimated fair value of the commitments to extend credit and letters of credit are insignificant and therefore are not presented in the above tables. |

| Commitments and Contingencies Disclosure [Abstract] | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Commitments and Contingent Liabilities | NOTE 11. COMMITMENTS AND CONTINGENT LIABILITIES Commitments — In the normal course of business, Wesbanco offers off-balance sheet credit arrangements to enable its customers to meet their financing objectives. Those instruments involve, to varying degrees, elements of credit and interest rate risk in excess of the amount recognized in the financial statements. Wesbanco’s exposure to credit losses in the event of non-performance by the other parties to the financial instruments for commitments to extend credit and standby letters of credit is limited to the contractual amount of those instruments. Wesbanco uses the same credit policies in making commitments and conditional obligations as for all other lending. 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. The allowance for credit losses associated with commitments was $7.2 million and $7.0 million at March 31, 2026 and December 31, 2025, respectively, and is included in other liabilities on the Consolidated Balance Sheets. Letters of credit are conditional commitments issued by banks to guarantee the performance of a customer to a third party. Those guarantees are primarily issued to support public and private borrowing arrangements, including normal business activities, bond financing and similar transactions. Letters of credit are considered guarantees. The liability associated with letters of credit was $0.4 million as of both March 31, 2026 and December 31, 2025. Contingent obligations to purchase loans funded by other entities include credit card guarantees, loans sold with recourse as well as obligations to the FHLB. Credit card guarantees are credit card balances not owned by Wesbanco, whereby the Bank guarantees the performance of the cardholder. The following table presents total commitments to extend credit, guarantees and various letters of credit outstanding:
Contingent Liabilities — Wesbanco is a party to various legal and administrative proceedings and claims. While any litigation contains an element of uncertainty, management does not believe that a material loss related to such proceedings or claims pending or known to be threatened is reasonably possible. |

| Business Segments | NOTE 12. BUSINESS SEGMENTS Wesbanco operates two reportable segments: community banking and trust and investment services. Wesbanco’s community banking segment offers a wide range of banking products and services through various delivery channels and business units, including commercial demand, individual demand and time deposit accounts; commercial, mortgage and individual installment loans, and certain non-traditional offerings, such as insurance and securities brokerage services. For purposes of determining the community banking reportable segment, these lines of business are aggregated, in accordance with the review of the Chief Operating Decision Maker ("CODM"). The trust and investment services segment offers trust services as well as various alternative investment products, including mutual funds, and also serves as investment adviser to a family of mutual funds called the “WesMark Funds.” The fund family is comprised of the WesMark Large Company Fund, the WesMark Balanced Fund, the WesMark Small Company Fund, the WesMark Government Bond Fund, the WesMark West Virginia Municipal Bond Fund, and the WesMark Tactical Opportunity Fund. Corporate support functions, which are generally all attributable to the parent company, do not represent a reportable segment and are presented within Corporate Other for purposes of reconciling to the consolidated financials. All of Wesbanco’s revenue is derived from domestic operations, and Wesbanco has no major customers providing greater than 10% of total segment revenue. Wesbanco’s CODM is its . The CODM uses net income as the reported measure of segment profit or loss in making business decisions regarding reinvestment into the Company’s segments, using profits for acquisitions and/or paying dividends to shareholders. In addition, net income is used to monitor budget versus actual results, to perform competitive analysis by benchmarking to peers and as a factor to establish compensation for certain employees. Wesbanco does not have any material intra-entity sales or transfers. The market value of trust assets totaled approximately $7.8 billion and $7.0 billion at March 31, 2026 and 2025, respectively. These assets are held by Wesbanco in fiduciary or agency capacities and are not included as assets on Wesbanco’s Consolidated Balance Sheets. Therefore, substantially all of Wesbanco’s assets are attributable to the community banking segment. The following tables present selected financial information with respect to Wesbanco’s business segments for the three months ended March 31, 2026 and 2025 as received and reviewed on a regular basis by the CODM:
(1) Within Corporate other, this represents interest expense on subordinated and junior subordinated debt issued by the parent company of Wesbanco. (2) The significant expense categories and amounts align with the segment-level information that is regularly provided to the CODM. (3) Includes depreciation and amortization expense of $2.1 million for the community banking segment. Such expenses for the trust and investment services segment are immaterial. (4) Includes depreciation and amortization expense of $2.9 million for the community banking segment. Such expenses for the trust and investment services segment are immaterial. (5) Corporate overhead expenses allocated to the trust and investment services segment consist of audit and accounting services, human resources, bank administration and information technology. (6) Other segment items included in segment expenses for the community banking segment include ATM and digital banking interchange expenses, correspondent service fee expense, postage expense, corporate insurance expense and other general banking service expenses. Other segment items included in segment expenses for the trust and investment services segment include postage expense, securities safekeeping expense and other miscellaneous operating expenses.

| Accounting Policies [Abstract] | |
| Basis of presentation | Basis of presentation — The accompanying unaudited interim financial statements of Wesbanco, Inc. and its consolidated subsidiaries (“Wesbanco” or the "Company") have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim financial information and the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements and should be read in conjunction with our Annual Report on Form 10-K for the year ended December 31, 2025. Wesbanco’s interim financial statements have been prepared following the significant accounting policies disclosed in Note 1 of the Notes to the Consolidated Financial Statements of its 2025 Annual Report on Form 10-K filed with the Securities and Exchange Commission ("SEC"), as well as with the policy changes indicated below. In the opinion of management, the accompanying interim financial information reflects all adjustments, including normal recurring adjustments, necessary to present fairly Wesbanco’s financial position and results of operations for each of the interim periods presented. Results of operations for interim periods are not necessarily indicative of the results of operations that may be expected for a full year. |
| Recent accounting pronouncements | Recent accounting pronouncements—The Financial Accounting Standards Board (“FASB”) issued Accounting Standards Updates (“ASU”) as noted below. ASU 2025‑12 — Codification Improvements In December 2025, the FASB issued ASU 2025‑12, “Codification Improvements.” This Update is part of the Board’s ongoing effort to address technical corrections, clarifications, and minor improvements across the FASB Accounting Standards Codification. These improvements refine the application of existing guidance, resolve inconsistencies, and improve the usability of the Codification without introducing significant changes to accounting practice or requiring substantial implementation effort. The amendments are not expected to significantly affect current practice. However, updates will be reviewed for any potential effects on accounting policies or disclosure processes. The amendments in this Update are effective for all entities for annual periods beginning after December 15, 2026, including interim periods within those annual periods. Early adoption is permitted. The adoption of this pronouncement is not expected to have a material impact on the Consolidated Financial Statements. ASU 2025‑11 — Interim Reporting (Topic 270): Narrow‑Scope Improvements In December 2025, the FASB issued ASU 2025‑11, “Interim Reporting (Topic 270): Narrow‑Scope Improvements.” The amendments are intended to improve the navigability and clarity of interim reporting requirements under Topic 270. The Update clarifies when Topic 270 applies, adds a comprehensive list of required interim disclosures, and introduces a disclosure principle requiring entities to disclose events occurring after the most recent annual period that have a material impact on the entity. The Update does not expand or reduce overall interim disclosure requirements but instead compiles and organizes them to improve consistency and comparability. The guidance also clarifies form‑and‑content expectations for interim financial statements, including the use of condensed statements, and aligns GAAP with prior SEC requirements regarding material events. The amendments are effective for interim reporting periods beginning after December 15, 2027, for public business entities and one year later for all other entities. Early adoption is permitted, with prospective or retrospective application available. The adoption of this pronouncement is not expected to have a material impact on the Consolidated Financial Statements. ASU 2025‑10 — Government Grants (Topic 832): Accounting for Government Grants Received by Business Entities In December 2025, the FASB issued ASU 2025‑10, “Government Grants (Topic 832): Accounting for Government Grants Received by Business Entities.” The amendments establish authoritative U.S. GAAP for the recognition, measurement, and presentation of government grants received by business entities. Historically, in the absence of explicit guidance, entities analogized to IAS 20 or ASC 958‑605, resulting in diversity in practice. ASU 2025‑10 adopts a model largely based on IAS 20, with revisions for U.S. GAAP. Under this Update, a government grant is defined as a transfer of a monetary or tangible nonmonetary asset from a governmental body in a non‑exchange transaction. The guidance excludes transactions such as income‑tax credits under Topic 740, below‑market interest rate loans, government guarantees, contributions from nongovernmental sources, and transfers of intangible assets or services. Recognition is required when it is probable that the entity will comply with grant conditions and the grant will be received. Grants related to assets are recognized as the related costs are incurred; grants related to income are recognized as the related expenses are incurred. The amendments are effective for public business entities for annual periods beginning after December 15, 2028, and one year later for all other entities. Early adoption is permitted. The adoption of this pronouncement is not expected to have a material impact on the Consolidated Financial Statements. ASU 2025-09 — Derivatives and Hedging (Topic 815): Hedging Accounting Improvements In November 2025, the FASB issued ASU 2025‑09, “Derivatives and Hedging (Topic 815): Hedge Accounting Improvements.” The amendments in this Update enhance and clarify several aspects of hedge accounting to better align financial reporting with the economics of an entity’s risk‑management activities. The guidance addresses key areas including similar risk assessments for groups of forecasted transactions, hedging of forecasted interest payments on “choose‑your‑rate” debt instruments, hedging of nonfinancial forecasted transactions, use of net written options as hedging instruments, and the treatment of foreign currency‑denominated debt in certain dual hedging strategies. The amendments allow a broader set of forecasted transactions to qualify for hedge accounting by focusing on “similar risk exposure” rather than requiring identical risk characteristics. Entities must evaluate this criterion at hedge inception and on an ongoing basis, using qualitative assessments where appropriate. The amendments in this Update are effective for public business entities for annual periods beginning after December 15, 2026, and one year later for all other entities. Early adoption is permitted. Adoption is prospective, with transition provisions available to facilitate migration of existing hedging relationships. The adoption of this pronouncement is not expected to have a material impact on the Consolidated Financial Statements. ASU 2025-08 — Financial Instruments—Credit Losses (Topic 326): Purchased Loans In November 2025, the FASB issued ASU 2025‑08, “Financial Instruments—Credit Losses (Topic 326): Purchased Loans.” The amendments in this update make significant changes to the accounting for certain acquired seasoned loans subject to CECL. The Board decided not to change the existing models for originated assets, purchased credit deteriorated ("PCD") assets or other acquired assets. Under the ASU, the initial allowance for credit losses recorded upon the acquisition of loans in scope is recognized as an adjustment to the amortized cost basis of the loan–similar to the PCD model. For these loans, the “day-one” credit loss estimate does not impact earnings immediately but rather is amortized over time as an adjustment to interest income. Subsequent changes in the allowance for credit losses are reported in earnings within credit loss expense. The amendments in this Update are effective for all entities for fiscal years beginning after December 15, 2026, including interim periods within those fiscal years, and are to be applied prospectively to loans acquired on or after the date of adoption. Early adoption is permitted. The adoption of this pronouncement is not expected to have a material impact on the Consolidated Financial Statements. ASU 2025-07 — Derivatives and Hedging (Topic 815) and Revenue from Contracts with Customers (Topic 606) In September 2025, the FASB issued ASU 2025-07, “Derivatives and Hedging (Topic 815) and Revenue from Contracts with Customers (Topic 606).” The amendments in this Update apply to all entities that enter into non exchange-traded contracts with underlyings based on operations or activities specific to one of the parties to the contract. The amendments in this Update exclude from derivative accounting non exchange-traded contracts with underlyings that are based on operations or activities specific to one of the parties to the contract. However, this scope exception does not apply to (1) variables based on a market rate, market price, or market index, (2) variables based on the price or performance of a financial asset or financial liability of one of the parties to the contract, (3) contracts (or features) involving the issuer’s own equity that are evaluated under the guidance in Subtopic 815-40, Derivatives and Hedging—Contracts in Entity’s Own Equity, and (4) call options and put options on debt instruments. The amendments in this Update are effective for all entities for annual reporting periods beginning after December 15, 2026, and interim reporting periods within those annual reporting periods. Early adoption is permitted. The adoption of this pronouncement is not expected to have a material impact on the Consolidated Financial Statements. ASU 2025-05 — Financial Instruments—Credit Losses (Topic 326) In July 2025, the FASB issued ASU 2025-05, “Financial Instruments – Credit Losses (Topic 326).” The amendments provide (1) all entities with a practical expedient when estimating expected credit losses for current accounts receivable and current contract assets arising from transactions accounted for under Topic 606 and (2) entities other than public business entities with an accounting policy election for those same asset classes. The amendments will be effective for annual reporting periods beginning after December 15, 2025, and interim reporting periods within those annual reporting periods. The Company adopted ASU 2025‑05 effective January 1, 2026 and elected the practical expedient for in-scope current accounts receivable and contract assets. Loans and other financial assets measured at amortized cost are not within the scope of this guidance. Therefore, the adoption of this pronouncement does not have a material impact on the Consolidated Financial Statements, including the allowance for credit losses. ASU 2025-01 & 2024-03 — Income Statement — Reporting Comprehensive Income –Expense Disaggregation Disclosures (Subtopic 220-40) In November 2024, the FASB issued ASU 2024-03, “Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures.” The amendments in this Update improve financial reporting by requiring that public business entities disclose additional information about specific expense categories in the notes to financial statements at interim and annual reporting periods. This information is generally not presented in the financial statements today. For Wesbanco, the amendments in this Update are effective for annual reporting periods beginning after December 15, 2026, and interim reporting periods beginning after December 15, 2027. Early adoption is permitted. In January 2025, the FASB issued ASU 2025-01, “Income Statement — Reporting Comprehensive Income – Expense Disaggregation Disclosures (Subtopic 220-40).” The amendment in this Update amends the effective date of ASU 2024-03 to clarify that all public business entities are required to adopt the guidance in annual reporting periods beginning after December 15, 2026, and interim periods within annual reporting periods beginning after December 15, 2027. Early adoption is permitted. The adoption of these pronouncements is not expected to have a material impact on the Consolidated Financial Statements, but is expected to result in additional disclosures and potential changes to the line items on the Consolidated Statement of Income. |
