NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of presentation — The accompanying unaudited interim financial statements of Wesbanco, Inc. and its consolidated subsidiaries (“Wesbanco”) 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, 2022.

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 2022 Annual Report on Form 10-K filed with the Securities and Exchange Commission, 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. Certain prior period amounts have been reclassified to conform to the current period presentation. Such reclassifications had no impact on Wesbanco’s net income and shareholders’ equity. Results of operations for interim periods are not necessarily indicative of the results of operations that may be expected for a full year.

Modifications for Borrowers Experiencing Financial Difficulty (“MBEFD”) — A modification of a loan for borrowers experiencing financial difficulty is applicable when the loan modification results in a direct change in the timing or amount of contractual cash flows. The most common modifications provided to borrowers experiencing financial difficulty are expected to occur in the form of principal forgiveness, interest rate reductions, other-than-insignificant-payment delays, or term extensions under ASC 310-10-50-39. Upon Wesbanco's adoption of Accounting Standards Update (“ASU”) 2022-02 on January 1, 2023, Troubled Debt Restructuring ("TDR") accounting was prospectively discontinued and economic concessions for modifications occurring on or after the adoption date are no longer measured. This accounting also results in the elimination of any existing economic concession related to a loan that was previously designated as a TDR if such loan is restructured on or after January 1, 2023. Due to the elimination of economic concessions under ASU 2022-02, the standard may result in modified loans being subject to the new disclosures that would have not been considered concessions and not treated as TDRs.

When determining whether a debtor is experiencing financial difficulties, consideration is given to any known default on any of its debt or whether it is probable that the debtor would be in payment default in the foreseeable future without the modification. Other indicators of financial difficulty include whether the debtor has declared or is in the process of declaring bankruptcy, the debtor’s ability to continue as a going concern, or the debtor’s projected cash flow to service its debt (including principal & interest) in accordance with the contractual terms for the foreseeable future, without a modification. If the payment of principal at original maturity is primarily dependent on the value of collateral, the current value of that collateral is considered in determining whether the principal will be paid.

The modification of a loan does not increase the allowance or provision for credit losses unless the loan is extended, or the loans are commercial loans that are individually evaluated for impairment, in which case a specific reserve is established pursuant to GAAP. Portfolio segment loss history is the primary factor for establishing the allowance for residential real estate, home equity and consumer MBEFDs.

Non-accrual loans that are restructured remain on non-accrual, but may move to accrual status after they have performed according to the restructured terms for a period of time. MBEFDs on accrual status generally remain on accrual as long as they continue to perform in accordance with their modified terms. MBEFDs may also be placed on non-accrual if they do not perform in accordance with the restructured terms. Loans may be removed from MBEFD status after they have performed according to the renegotiated terms for a period of time.

Recent accounting pronouncements—The Financial Accounting Standards Board (“FASB”) issued Accounting Standards Updates (“ASU”) as noted below.

ASU 2023-02 – Investments Equity Method and Joint Ventures (Topic 323)

In March 2023, the FASB issued ASU 2023-02, Investments—Equity Method and Joint Ventures (Topic 323): Accounting for Investments in Tax Credit Structures Using the Proportional Amortization Method. ASU 2023-02 allows reporting entities to elect to account for qualifying tax equity investments using the proportional amortization method, regardless of the program giving rise to the related income tax credits. The ASU’s amendments “remove the specialized guidance for [low-income-housing tax credit] investments that are not accounted for using the proportional amortization method and instead require that those LIHTC investments be accounted for using the guidance in other [GAAP].” For Wesbanco, the amendments are effective for fiscal years beginning after December 15, 2023, including interim periods within those fiscal years. The adoption of this pronouncement is not expected to have a material impact on the Consolidated Financial Statements.

ASU 2023-01 - Leases (Topic 842): Common Control Arrangements

In March 2023, the FASB issued ASU 2023-01, Leases (Topic 842): Common Control Arrangements. ASU 2023-01 amends certain provisions of ASC 842 that apply to arrangements between related parties under common control. Additionally, ASU 2023-01 amends the accounting for leasehold improvements in common-control arrangements for all entities. For Wesbanco, the amendments are effective for fiscal years beginning after December 15, 2023, including interim periods within those fiscal years. Early adoption is permitted in any annual or interim period as of the beginning of the related fiscal year. The adoption of this pronouncement is not expected to have a material impact on the Consolidated Financial Statements.

7

ASU 2022-04 Liabilities – Supplier Finance Programs (Sub-topic 405-50)

In September 2022, the FASB issued ASU 2022-04, “Liabilities—Supplier Finance Programs (Subtopic 405-50).” The amendments in this ASU require that a buyer in a supplier finance program disclose sufficient information about the program to allow a user of financial statements to understand the program’s nature, activity during the period, changes from period to period, and potential magnitude. To achieve that objective, the buyer should disclose qualitative and quantitative information about its supplier finance programs. For Wesbanco, this update was effective beginning on January 1, 2023, except for the amendment on rollforward information, which is effective for fiscal years beginning after December 15, 2023. The adoption of this full pronouncement is not expected to have a material impact on the Consolidated Financial Statements.

ASU 2022-03 Fair Value Measurement (Topic 820)

In June 2022, the FASB issued ASU 2022-03, "Fair Value Measurement (Topic 820).” The amendments in this ASU clarify that a contractual restriction on the sale of an equity security is not considered part of the unit of account of the equity security, and therefore, is not considered in measuring fair value. Furthermore, the amendments to this ASU clarify that an entity cannot, as a separate unit of account, recognize and measure a contractual sale restriction. The update to this ASU requires the following disclosures for equity securities: (1) The fair value of equity securities subject to contractual sale restrictions reflected in the balance sheet; (2) The nature and remaining duration of the restriction(s) and; (3) The circumstances that could cause a lapse in the restriction(s). The amendments in this Update are effective for fiscal years beginning after December 15, 2023, and interim periods within those fiscal years. Wesbanco is currently assessing the impact of ASU 2022-03 on its Consolidated Financial Statements.

ASU 2022-02 Financial Instruments - Credit Losses (Topic 326)

In March 2022, the FASB issued ASU 2022-02, "Financial Instruments - Credit Losses (Topic 326)." The amendments in this ASU eliminate the accounting guidance for TDRs by creditors in Subtopic 310-40, "Receivables - Troubled Debt Restructurings by Creditors," while enhancing disclosure requirements for certain loan refinancings and restructurings by creditors when a borrower is experiencing financial difficulty. Specifically, rather than applying the recognition and measurement guidance for TDRs, an entity must apply the loan refinancing and restructuring guidance in paragraphs 310-20-35-9 through 35-11 to determine whether a modification results in a new loan or a continuation of an existing loan. In addition, for public business entities, the amendments in this Update require that an entity disclose current-period gross writeoffs by year of origination for financing receivables and net investments in leases within the scope of Subtopic 326-20, "Financial Instruments - Credit Losses - Measured at Amortized Cost." For Wesbanco, this update was effective beginning on January 1, 2023. The adoption of this pronouncement did not have a material impact on the Consolidated Financial Statements. For the additional disclosure requirements in this ASU, please refer to Footnote 4, "Loans and the Allowance for Credit Losses."

ASU 2020-04, ASU 2021-01 and ASU 2022-06 Reference Rate Reform (Topic 848)

In March 2020, the FASB issued ASU 2020-04, “Reference Rate Reform (Topic 848).” This ASU provided temporary, optional guidance to ease the potential burden in accounting for, or recognizing the effects of, the transition away from the London Interbank Offered Rate ("LIBOR") or other reference rate expected to be discontinued on financial reporting. The ASU also provides optional expedients for contract modifications that replace a reference rate affected by reference rate reform. The guidance is effective as of March 12, 2020 through December 31, 2022, and can be adopted at any time during this period. In January 2021, the FASB issued ASU 2021-01, “Reference Rate Reform (Topic 848): Scope.” This ASU refines the scope of Topic 848 and addresses questions about whether Topic 848 can be applied to derivative instruments that do not reference a rate that is expected to be discontinued, but that use an interest rate for margining, discounting or contract price alignment that is expected to be modified as a result of reference rate reform. ASU 2021-01 is effective upon issuance through December 31, 2024, and can be adopted at any time during this period. Wesbanco has not offered LIBOR for any new contracts after December 31, 2021. Wesbanco has chosen the One Month Term Secured Overnight Financing Rate ("1M Term SOFR") as its alternative replacement rate for LIBOR on both back-to-back swaps and on one-month variable loans. A transition plan was implemented in 2021 to identify and modify Wesbanco's loans and other financial instruments with attributes that are either directly or indirectly influenced by LIBOR, and Wesbanco continues to assess the impact of adopting the new guidance on the consolidated financial statements on an ongoing basis, with no material impacts expected at this time. In December 2022, the FASB issued ASU 2022-06, “Reference Rate Reform (Topic 848): Deferral of the Sunset Date of Topic 848.” In the Update, the Board decided to defer the sunset date of Topic 848 to December 31, 2024, to permit entities to apply the guidance in Topic 848 through the expected cessation date of USD LIBOR. In the Board’s view, that time frame would have been sufficient to provide flexibility for additional unforeseen changes to the timeline of USD LIBOR cessation and to accommodate global interbank offered rate (IBOR) transition. The update is not expected to have a material impact on Wesbanco’s Consolidated Financial Statements.

NOTE 2. EARNINGS PER COMMON SHARE

Earnings per common share are calculated as follows:

	For the Three Months Ended March 31,
(unaudited, in thousands, except shares and per share amounts)	2023		2022
Numerator for both basic and diluted earnings per common share:
Net income available to common shareholders	$	39,810	$	41,593
Denominator:
Total average basic common shares outstanding		59,217,711		61,445,399
Effect of dilutive stock options and other stock compensation		157,342		147,966
Total diluted average common shares outstanding		59,375,053		61,593,365
Earnings per common share - basic	$	0.67	$	0.68
Earnings per common share - diluted	$	0.67	$	0.68

As of March 31, 2023 and 2022, 483,011 and 384,761 options to purchase shares were not included in the diluted share computation for the three months ended March 31, 2023 and 2022, 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, 2023, an aggregate of 42,624 contingently issuable shares were estimated to be awarded under the 2022 and 2021 total shareholder return ("TSR") plans, as stock performance targets had been met as of such date and therefore those shares were included in the diluted calculation. No shares related to the 2023 plan were included because the effect would be antidilutive. As of March 31, 2022, 16,224 contingently issuable shares were estimated to be awarded under the 2022 TSR plan, as stock performance targets had been met as of such date and therefore those shares were included in the diluted calculation. As of March 31, 2022, the shares related to the 2021 and 2020 TSR plans were not included in the calculation because the effect would be antidilutive.

In addition, performance-based restricted stock ("PBRS") compensation totaling 61,510 and 61,267 shares were estimated to be awarded as of March 31, 2023 and March 31, 2022, respectively.

(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, 2023 and December 31, 2022, respectively.

At March 31, 2023 and December 31, 2022, 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 $9.3 million 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 $11.8 million and $11.5 million at March 31, 2023 and December 31, 2022, 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, 2023. 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 fair value of $2.1 billion at March 31, 2023 and December 31, 2022, respectively, were pledged as security for public and trust funds, and securities sold under agreements to repurchase. Proceeds from the sale of available-for-sale securities for the three months ended March 31, 2023 and 2022 totaled $20.5 million and $0 million, respectively. Net unrealized losses on available-for-sale securities included in accumulated other comprehensive income, net of tax, as of March 31, 2023 and December 31, 2022 were $233.9 million and $261.8 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, 2023 and 2022, respectively. All gains and losses presented in the table below are included in the net securities gains (losses) line item of the 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 income statement in the provision for credit losses. Accrued interest receivable on held-to-maturity securities, which was $9.3 million and $9.5 million as of March 31, 2023 and December 31, 2022, 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, 2023 and 2022:

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 Federal Home Loan Bank (“FHLB”) of Pittsburgh stock totaling $59.2 million and $36.2 million at March 31, 2023 and December 31, 2022, 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.

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 $10.3 million and $9.6 million at March 31, 2023 and December 31, 2022, respectively. The un-accreted discount on purchased loans from acquisitions was $16.7 million at March 31, 2023 and $18.0 million at December 31, 2022.

As of March 31, 2023, accrued interest receivable for loans was $53.0 million. 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, Wesbanco does have a $0.2 million reserve on the accrued interest related to loan modifications allowed under the Coronavirus Aid, Relief and Economic Security ("CARES") Act due to the timing and nature of these modifications. As of March 31, 2023, accrued interest related to COVID-19 loan modifications as permitted under the CARES Act was $16.7 million.

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.

15

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.

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 $20.4 million at March 31, 2023 and $24.8 million at December 31, 2022, of which $2.6 million and $5.9 million were accruing, for each period, respectively. These loans are not included in the tables above. In addition, $30.3 million and $25.0 million of unfunded commercial loan commitments are also not included in the tables above at March 31, 2023 and December 31, 2022, respectively.

NOTE 5. 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 Bank's assets and liabilities 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, 2023 and December 31, 2022, Wesbanco had 169 and 159 customer interest rate swaps and caps with an aggregate notional amount of $1.1 billion and $0.9 billion, respectively, related to this program. Wesbanco recognized income for the related swap and cap fees of $1.8 million and $0.2 million for the three months ended March 31, 2023 and 2022, 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, 2023 and December 31, 2022, Wesbanco had 17 and 16 risk participation-in agreements with an aggregate notional amount of $195.1 million and $187.8 million, respectively. As of March 31, 2023 and December 31, 2022, Wesbanco had one risk participation-out agreement with an aggregate notional amount of $9.5 million and $9.6 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 $40.0 million and $14.5 million at March 31, 2023 and December 31, 2022, 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, 2023 and December 31, 2022:

Total		$	(1,041	)	$	2,586

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. If Wesbanco had breached any of these provisions at March 31, 2023, 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. In certain market situations, Wesbanco can also request collateral from the derivative counterparties. Due to the recent rise in interest rates, as of March 31, 2023, Wesbanco is holding collateral from various derivative counterparties with a market value of $27.6 million.

NOTE 6. BENEFIT PLANS

The following table presents the net periodic pension income for Wesbanco’s Defined Benefit Pension Plan (the “Plan”) and the related components:

	For the Three Months Ended March 31,
(unaudited, in thousands)	2023			2022
Service cost – benefits earned during year	$	350		$	540
Interest cost on projected benefit obligation		1,554			1,013
Expected return on plan assets		(2,750	)		(2,853	)
Amortization of prior service cost		(9	)		(8	)
Amortization of net loss		223			125
Net periodic pension income	$	(632	)	$	(1,183	)

The service cost of $0.4 million and $0.5 million for the three months ended March 31, 2023 and 2022, respectively, is included in salaries and wages, and periodic pension income of $1.0 million and $1.7 million for the three months ended March 31, 2023 and 2022, respectively, is included in employee benefits.

The Plan covers all employees of Wesbanco and its subsidiaries who were hired on or before August 1, 2007 who satisfy minimum age and length of service requirements, and is not available to employees hired after such date.

A minimum required contribution is not required for 2023, and Wesbanco currently does not expect to make a voluntary contribution to the Plan in 2023.

NOTE 7. 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.

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.

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 table 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, 2023 and December 31, 2022:

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 significant transfers between level 1, 2 or 3 for the three months ended March 31, 2023 or for the year ended December 31, 2022.

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:

	Quantitative Information about Level 3 Fair Value Measurements

(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.

Net loans: Fair values for loans are estimated 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.

NOTE 8. REVENUE RECOGNITION

Interest income, net securities gains (losses) and bank-owned life insurance are not in scope of ASC 606, Revenue from Contracts with Customers. For the revenue streams in scope of ASC 606 - trust fees, service charges on deposits, net securities brokerage revenue, payment processing fees, electronic banking fees, mortgage banking income and net gain or loss on sale of other real estate owned and other assets – there are no significant judgements related to the amount and timing of revenue recognition.

The following table summarizes the point of revenue recognition and the income recognized for each of the revenue streams for the three months ended March 31, 2023 and 2022, respectively:

NOTE 10. 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 $9.1 million and $8.4 million at March 31, 2023 and December 31, 2022, 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 $0.3 million and $0.2 million as of March 31, 2023 and December 31, 2022, respectively.

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:

	March 31,		December 31,
(unaudited, in thousands)	2023		2022
Lines of credit	$	3,938,353	$	3,806,398
Loans approved but not closed		548,801		398,204
Overdraft limits		391,322		380,143
Letters of credit		32,317		30,362
Contingent obligations and other guarantees		21,682		30,782

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.

NOTE 11. BUSINESS SEGMENTS

Wesbanco operates two reportable segments: community banking and trust and investment services. Wesbanco’s community banking segment offers services traditionally offered by full-service commercial banks, including commercial demand, individual demand and time deposit accounts, as well as commercial, mortgage and individual installment loans, and certain non-traditional offerings, such as insurance and securities brokerage services. The trust and investment services segment offers trust services as well as various alternative investment products including mutual funds. The market value of assets managed or held in custody by the trust and investment services segment was approximately $5.0 billion and $5.4 billion at March 31, 2023 and 2022, respectively. These assets are held by Wesbanco in fiduciary or agency capacities for their customers and therefore are not included as assets on Wesbanco’s Consolidated Balance Sheets.

OVERVIEW

Wesbanco is a multi-state bank holding company operating through 194 branches and 185 ATM machines in West Virginia, Ohio, western Pennsylvania, Kentucky, southern Indiana and Maryland, offering retail banking, corporate banking, personal and corporate trust services, brokerage services, mortgage banking and insurance. Wesbanco’s businesses are significantly impacted by economic factors such as market interest rates, federal monetary and regulatory policies, local and regional economic conditions and the competitive environment’s effect upon Wesbanco’s business volumes. Wesbanco’s deposit levels are affected by numerous factors including personal savings rates, personal income, and competitive rates on alternative investments, as well as competition from other financial institutions within the markets we serve and liquidity needs of Wesbanco. Loan levels are also subject to various factors including construction demand, business financing needs, consumer spending and interest rates, as well as loan terms offered by competing lenders.

APPLICATION OF CRITICAL ACCOUNTING POLICIES AND ESTIMATES

Wesbanco’s critical accounting policies involving the significant judgments and assumptions used in the preparation of the Consolidated Financial Statements as of March 31, 2023 have remained unchanged from the disclosures presented in Wesbanco’s Annual Report on Form 10-K for the year ended December 31, 2022 within the section “Management’s Discussion and Analysis of Financial Condition and Results of Operations.”

RESULTS OF OPERATIONS

EARNINGS SUMMARY

Net income available to common shareholders for the first quarter of 2023 was $39.8 million, with diluted earnings per share of $0.67, compared to $41.6 million or $0.68 per diluted share, respectively, for the first quarter of 2022. Net income available to common shareholders, excluding after-tax restructuring and merger-related expenses, for the three months ended March 31, 2023, was $42.3 million or $0.71 per diluted share, as compared to $42.9 million or $0.70 per diluted share, respectively, in the prior year quarter (non-GAAP measures).

	For the Three Months Ended March 31,
	2023						2022
(unaudited, dollars in thousands, except per share amounts)	Net Income			Diluted Earnings Per Share			Net Income			Diluted Earnings Per Share
Net income available to common shareholders (Non-GAAP)(1)	$	42,301		$	0.71		$	42,851		$	0.70
Less: After-tax restructuring and merger-related expenses		(2,491	)		(0.04	)		(1,258	)		(0.02	)
Net income available to common shareholders (GAAP)	$	39,810		$	0.67		$	41,593		$	0.68

(1)Non-GAAP net income excludes after-tax restructuring and merger-related expenses. The above non-GAAP financial measures used by Wesbanco provide information useful to investors in understanding Wesbanco’s operating performance and trends, and facilitate comparisons with the performance of Wesbanco’s peers.

Net interest income increased $16.6 million or 15.4% in the first quarter of 2023 compared to the same quarter of 2022, due to the 425 basis point increase in the federal funds rate through February 2023. Higher yields in all earning asset categories, due to the repricing of existing loans and higher investment rates offered in the current market environment, resulted in a 41 basis point increase in the net interest margin in the first quarter of 2023 as compared to the first quarter of 2022. Over the same time period, the yield on earning assets increased by a total of 125 basis points while the cost of interest bearing liabilities increased 133 basis points. Average loan balances increased by 10.7% from the first quarter of 2022, mainly attributable to higher new loan demand, partially offset by forgiveness of PPP loans and higher levels of commercial real estate loan payoffs, while average securities increased by 1.0% over the same time period due to investment purchases occurring in the first half of 2022. Average deposits decreased 5.8% over the same time period as a result of interest rate and inflationary pressures and rising costs across the economy. Accretion from prior acquisitions benefited the first quarter 2023 net interest margin by 4 basis points, as compared to 8 basis points in the prior year period.

Loan growth and slower prepayment speeds resulted in a provision of $3.6 million in the first quarter of 2023, as compared to a negative provision of $3.4 million in the first quarter of 2022. Annualized net loan charge-offs, as a percentage of average portfolio loans, were 0.07% and 0.00% for the first quarter of 2023 and 2022, respectively.

For the first quarter of 2023, non-interest income decreased $2.7 million or 9.0% compared to the first quarter of 2022, driven primarily by lower bank-owned life insurance and mortgage banking income, which decreased by $1.9 million and $1.5 million, respectively, from the first quarter of 2022. Bank-owned life insurance decreased due to $1.9 million of death benefits received in the first quarter of 2022, compared to none in the first quarter of 2023. Mortgage banking income decreased due to a reduction in residential mortgage originations, primarily driven by the higher interest rate environment and retention of more residential mortgages on the balance sheet as production continues to migrate towards shorter-term adjustable rate mortgage products. First quarter 2023 mortgage originations decreased by 40.3% from the first quarter of 2022. New commercial swap fees, which are recorded in other income, increased $1.7 million from the prior year period to $1.8 million, while associated fair market value adjustments totaled negative $1.0 million during the first quarter, as compared to a positive $1.5 million last year.

Non-interest expense, excluding restructuring and merger-related expenses, increased in the first quarter of 2023 by $7.0 million or 8.2%, to $93.0 million, compared to the first quarter of 2022. Salaries and wages increased $3.0 million or 7.7% from the first quarter of 2022 to the first quarter of 2023 due to higher staffing levels, mostly revenue-producing positions, and normal merit increases. Employee benefits expense increased $2.9 million from last year's first quarter due to higher staffing levels, increased pension expense and higher health insurance contributions. FDIC insurance expense increased by $1.4 million in the first quarter of 2023 from the first quarter of 2022 due to the two basis point increase in the minimum rate for all banks.

During the first quarter of 2023, the effective tax rate was 19.0% as compared to 18.3% in last year’s first quarter, and the provision for income taxes increased by $0.1 million over the same time period. The increase in the effective tax rate from last year's first quarter is attributable to lower bank-owned life insurance income in 2023 as compared to 2022.

Net interest income, which is Wesbanco’s largest source of revenue, is the difference between interest income on earning assets, primarily loans and securities, and interest expense on liabilities, primarily deposits and short and long-term borrowings. Net interest income is affected by the general level of, and changes in interest rates, the steepness and shape of the yield curve, changes in the amount and composition of interest earning assets and interest bearing liabilities, as well as the frequency of repricing of existing assets and liabilities. Net interest income increased $16.6 million or 15.4% in the first quarter of 2023 compared to the first quarter of 2022, due to a 41 basis point increase in the net interest margin to 3.36% resulting from the 425 basis point increase in the federal funds rate from April 2022 through February 2023, as the yield on earning assets increased at a faster rate than the rate on interest bearing liabilities, slightly offset by lower purchase accounting accretion. Portfolio loans increased by 11.9% from March 31, 2022, due to higher new loan demand and internal initiatives to improve lending efficiencies. Total purchase accounting accretion continued to decrease in the first quarter of 2023 as compared to the first quarter of 2022, as approximately 4 basis points of accretion from prior acquisitions was included in the first quarter 2023 net interest margin as compared to 8 basis points in the 2022 first quarter net interest margin. Total average deposits, excluding CDs, decreased in the first quarter of 2023 by $396.3 million or 3.2% compared to the first quarter of 2022. The cost of interest bearing deposits increased by 88 basis points and the cost of total interest bearing liabilities increased by 133 basis points from the first quarter of 2022 to the first quarter of 2023. The increase in the cost is primarily due to rate increases for interest bearing deposits in response to the general increase in overall borrowing rates in the marketplace resulting from the previously mentioned federal fund rate increases in 2022 and 2023.

Interest income increased $48.4 million or 43.1% in the first quarter of 2023 compared to the same period of 2022 due to the 425 basis point federal funds rate increases between April of 2022 and February of 2023. Earning asset yields were influenced positively as market rates started to increase in the second half of 2022 and first quarter of 2023. Average loan balances increased $1.0 billion or 10.7% in the first quarter of 2023 compared to the first quarter of 2022, while loan yields increased by 114 basis points during this same period to 5.03% due to the previously mentioned rising rate environment and its effect on the repricing of portfolio loans, as well as higher offered rates on new loans. Loans provide the greatest impact on interest income and the yield on earning assets as they have the largest balance and the highest yield within major earning asset categories. In the first quarter of 2023, average loans represented 70.8% of average earning assets, an increase from 65.0% in the first quarter of 2022. Average total securities balances increased $40.1 million or 1.0% from the first quarter of 2022, and represented 27.0% of total earning assets in the first quarter of 2023. Taxable securities yields increased by 63 basis points in the first quarter of 2023 from the first quarter of 2022 due to the increased rate environment for this type of security. Tax-exempt securities yields, which are the highest yields within total securities, remained relatively flat with an increase of 1 basis point from the first quarter of 2022 to the first quarter of 2023.

Interest expense increased $31.8 million in the first quarter of 2023 as compared to the same period in 2022, due to the timing of the previously mentioned federal funds rate increases and their effect on the costs of deposits and borrowings. The cost of interest bearing liabilities increased by 133 basis points from the first quarter of 2022 to 1.52% in the first quarter of 2023. Average interest bearing deposits decreased $791.7 million or 8.7% from the first quarter of 2022, due specifically to an 11.0% decrease in average interest bearing demand deposits, a 9.6% decrease in average money market accounts, and a 31.2% decrease in average certificates of deposit. The rate on interest bearing deposits increased 88 basis points to 1.00% from the first quarter of 2022, primarily from increases in rates on interest bearing public funds, money market funds and savings deposits, which were previously near their floors. Average non-interest bearing demand deposit balances increased from the first quarter of 2022 to the first quarter of 2023 by $3.4 million or 0.1%, and were 35.6% of total average deposits at March 31, 2023, compared to 33.5% at March 31, 2022, reflecting customers’ preferences and ongoing checking account marketing strategies. The average balance of FHLB borrowings increased $790.0 million from the first quarter of 2022 to 2023, due to increased loan funding demand. Average repurchase agreements combined with subordinated debt and junior subordinated debt balances increased $108.8 million or 35.8% from the first quarter of 2022 to 2023, due primarily to the subordinated debt issuance late in the first quarter of 2022.

PROVISION FOR CREDIT LOSSES – LOANS AND LOAN COMMITMENTS

The provision for credit losses – loans is the amount to be added to the allowance for credit losses – loans after net (charge-offs) recoveries have been (deducted) added to bring the allowance to a level considered appropriate to absorb lifetime expected losses for all portfolio loans. The provision for credit losses – loan commitments is the amount to be added to the allowance for credit losses for loan commitments to bring that allowance to a level considered appropriate to absorb lifetime expected losses on unfunded loan commitments. The provision for credit losses - loans and loan commitments increased to $3.6 million in the first quarter of 2023 compared to a negative provision of $3.4 million in the first quarter of 2022. While the provision increased year-over-year, the $3.6 million provision in the first quarter of 2023 was a result of an increase to the bank’s quantitative results and interest rate risk. Non-performing loans were 0.36% of total loans as of March 31, 2023, decreasing from 0.38% of total loans at the end of the first quarter of 2022. Criticized and classified loans were 1.60% of total loans as of March 31, 2023, decreasing from 3.68% as of March 31, 2022, primarily due to risk rating improvements. Past due loans at March 31, 2023 were 0.16% of total loans, compared to 0.35% at March 31, 2022. Annualized net loan charge-offs increased to 0.07% for the three months ended March 31, 2023 compared to 0.00% for the three months ended March 31, 2022.

Non-interest income is a significant source of revenue and an important part of Wesbanco’s results of operations, as it represents 18.2% of total revenue for the three months ended March 31, 2023. Wesbanco offers its customers a wide range of retail, commercial, investment and electronic banking services, which are viewed as a vital component of Wesbanco’s ability to attract and maintain customers, as well as providing additional fee income beyond normal spread-related income to Wesbanco. For the first quarter of 2023, non-interest income decreased $2.7 million or 9.0% compared to the first quarter of 2022, primarily due to a $1.9 million decrease in bank-owned life insurance, a $1.5 million decrease in mortgage banking income, a $0.8 million decrease in net swap fee and valuation income and a $0.7 million decrease in electronic banking fees. The decreases were somewhat offset by a $1.0 million increase in net gain (loss) on other real estate owned and other assets and a $0.8 million increase in net securities gains (losses).

Trust fees decreased $0.3 million or 4.4% compared to the first quarter of 2022, due to market value declines. Total trust assets were $5.0 billion at March 31, 2023 as compared to $5.4 billion at March 31, 2022. As of March 31, 2023, trust assets include managed assets of $4.0 billion and non-managed (custodial) assets of $1.0 billion. Assets managed for the WesMark Funds, a proprietary group of mutual funds that is advised by Wesbanco Trust and Investment Services, were $0.8 billion and $1.0 billion as of March 31, 2023 and March 31, 2022, respectively, and are included in managed assets.

Bank-owned life insurance decreased $1.9 million or 49.5% compared to the first quarter of 2022 due to a decrease in mortality-related benefits received in the first quarter of 2023. No mortality-related benefits were received in the first quarter of 2023.

Net securities gains (losses) include both gains and losses on investment security transactions as well as market value adjustments on the Company's deferred compensation plan. For the three months ended March 31, 2023, net securities gains (losses) increased $0.8 million compared to the same period of 2022, due to a $0.2 million increase in market adjustments on the deferred compensation plan in the first quarter of 2023 as compared to a $0.5 million decrease in the first quarter of 2022. These market adjustments had an offsetting effect in employee benefits expense.

Mortgage banking income decreased $1.5 million or 77.8% in the first quarter of 2023 compared to the first quarter of 2022, as mortgage originations decreased due to the current market environment. Wesbanco retained more 1-to-4 family mortgages on the balance sheet as production continues to migrate towards shorter-term adjustable rate mortgage products. For the first quarter of 2023, mortgage production was $161.7 million, which decreased by 40.3% from the first quarter of 2022. For the three months ended March 31, 2023, $39.9 million in mortgages were sold into the secondary market at a net margin of 1.1% as compared to $78.7 million at a net margin of 2.4% in the comparable 2022 period. Included in mortgage banking income and the calculation of net margin noted above are gains of $28 thousand and $0.8 million from the fair value adjustments on mortgage loan commitments and related derivatives for the three months ended March 31, 2023 and 2022, respectively.

Net gain (loss) on other real estate owned and other assets increased $1.0 million or 128.8% in the three months ended March 31, 2023 as compared to the same period in 2022, due mostly to a negative market value adjustment of $1.2 million recorded in the first quarter of 2022 on an investment made by Wesbanco’s CDC in a start-up firm more than ten years ago that was acquired by a public company in 2021. This investment was sold later in 2022.

Net swap fee and valuation income, which includes fair value adjustments, decreased $0.8 million in the first quarter of 2023 compared to the first quarter of 2022, due to negative fair value adjustments on the swap portfolio in 2023 as compared to 2022. For the three months ended March 31, 2023, new swaps executed totaled $162.6 million in notional principal, resulting in $1.8 million of fee income, compared to new swaps executed of $7.4 million in notional principal resulting in $0.2 million of fee income for the three months ended March 31, 2022. Fair value adjustments on existing swaps for the three months ended March 31, 2023 were a negative $1.0 million as compared to a positive $1.5 million for the three months ended March 31, 2022.

Non-interest expense in the first quarter of 2023 increased $8.6 million or 9.8% as compared to the same quarter in 2022, principally from a $3.0 million increase in salaries and wages, a $2.9 million increase in employee benefits, a $1.6 million increase in restructuring and merger-related expenses, a $1.4 million increase in FDIC insurance expense and a $1.1 million increase in equipment and software expense. These increases were slightly offset by a $1.0 million decrease in consulting, regulatory, accounting and advisory fees and a $0.6 million decrease in net occupancy. Excluding restructuring and merger-related expenses, non-interest expense increased $7.0 million or 8.2% from the first quarter of 2022 to the first quarter of 2023.

Salaries and wages increased $3.0 million or 7.7% in the first quarter of 2023 as compared to the first quarter of 2022 due to higher salary expense related to higher staffing levels in revenue-producing positions, and normal merit increases. Average full time equivalent employees increased by 2.0% from the first quarter of 2022 to the first quarter of 2023 due to targeted hiring of loan officers.

Employee benefits expense increased by $2.9 million or 31.7% in the first quarter of 2023 as compared to the first quarter of 2022. This increase was due to a $0.6 million increase in deferred compensation plan expense, which relates to the increase in the market value of the underlying investments, a $0.7 million increase in pension expense, a $0.8 million increase in health insurance contributions and increases in other employee benefits categories due to the increase in FTEs.

Equipment and software costs increased $1.1 million or 13.1% in the first quarter of 2023 as compared to the first quarter of 2022, due primarily to general inflationary cost increases for existing service agreements as well as the planned upgrade to one-third of Wesbanco's ATM fleet with the latest technology.

FDIC insurance expense increased $1.4 million or 89.5% in the first quarter of 2023 as compared to the first quarter of 2022 due primarily to the two basis point increase in the minimum FDIC assessment rate for all banks.

Restructuring and merger-related expenses in the first quarter of 2023 totaled $3.2 million, an increase of $1.6 million as compared to the first quarter of 2022. The expenses in both periods consisted of fixed asset writedowns and lease termination expenses associated with the closure of branches and back-office buildings as a result of the continued execution of the branch optimization strategy.

Consulting, regulatory, accounting and advisory fees decreased $1.0 million or 26.8% from the first quarter of 2022 to the first quarter of 2023, due particularly to decreases in regulatory examination fees and consulting fees.

INCOME TAXES

The provision for income taxes was $9.9 million for the three months ended March 31, 2023, which is a $0.1 million increase compared to the provision for the three months ended March 31, 2022. The increase in the provision for income taxes is due to an increase in the effective tax rate from 18.3% in the first quarter of 2022 to 19.0% in the first quarter of 2023. This increase is attributable to lower bank-owned life insurance income in 2023 as compared to 2022.

39

FINANCIAL CONDITION

Total assets and shareholders’ equity each increased 2.0%, while total deposits decreased 2.0% compared to December 31, 2022. Total securities decreased $72.2 million or 1.9% from December 31, 2022 to March 31, 2023, primarily driven by $74.1 million in paydowns on securities and $20.5 million in security sales, partially offset by a $36.8 million improvement in the unrealized loss position of the available-for-sale securities portfolio. Total portfolio loans increased $186.0 million or 1.7% as new originations outpaced pay downs. Deposits decreased $257.9 million, or 2.0% from December 31, 2022, as decreases of 0.2%, 3.0% and 3.9% in certificates of deposit, demand deposits and money market deposits, respectively, were partially offset by increase of 1.6% in savings deposits. The overall decrease in transaction-based accounts is primarily attributable to inflationary pressure and rising costs across the country causing a decrease in personal savings. Deposits declined by approximately $360 million early during the quarter and remained flat through February and March. Deposits were also somewhat impacted by bonus and royalty payments for Marcellus and Utica shale gas payments from energy companies in Wesbanco’s southwestern Pennsylvania, eastern Ohio, and northern West Virginia markets. The balance in certificates of deposit is virtually unchanged from December 31, 2022. Total borrowings increased 49.2% or $551.3 million during the first three months of 2023, which was primarily due to $575.0 million in new FHLB advances and partially offset by a $23.9 million decrease in other short-term borrowings. Total shareholders’ equity increased approximately $48.8 million or 2.0%, compared to December 31, 2022, primarily due to a $28.0 million increase in other comprehensive income, and net income exceeding cash dividends for the period by $19.2 million.

(1)At March 31, 2023 and December 31, 2022, 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.

(2)Weighted average yields have been calculated on a taxable-equivalent basis using the federal statutory tax rate of 21%.

Total investment securities, which are a source of liquidity for Wesbanco as well as a contributor to interest income, decreased by $72.2 million or 1.9% from December 31, 2022 to March 31, 2023. Through the first three months of the year, the available-for-sale portfolio decreased by $63.1 million or 2.5%, primarily due to $72.1 million in paydowns, $20.5 million in sales and $5.7 million in maturities and calls, partially offset by a decrease of $36.8 million in unrealized losses. The held-to-maturity portfolio decreased by $9.4 million or 0.8% due to maturities of municipal securities. The weighted average yield of the portfolio increased 3 basis points from 2.45% at December 31, 2022 to 2.48% at March 31, 2023, primarily due to increases in the indices tied to variable rate securities.

40

Total gross unrealized securities losses decreased $68.5 million from $510.7 million at December 31, 2022 to $442.2 million at March 31, 2023. The decrease in unrealized losses from December 31, 2022 was due to the decrease in market rates in 2023 to date, causing market prices to increase slightly on the portfolio. Wesbanco did not allocate any allowance for credit losses to the unrealized losses on available-for-sale debt securities at March 31, 2023. Please refer to Note 4, “Securities,” of the Consolidated Financial Statements for additional information. Wesbanco does not have any investments in private mortgage-backed securities or those that are collateralized by sub-prime mortgages, nor does Wesbanco have any exposure to collateralized debt obligations or government-sponsored enterprise preferred stocks.

Net unrealized losses on available-for-sale securities included in accumulated other comprehensive income, net of tax, as of March 31, 2023 and December 31, 2022 were $233.9 million and $261.8 million, respectively. These net unrealized pre-tax losses represent temporary fluctuations resulting from changes in market rates in relation to fixed yields in the available-for-sale portfolio, and on an after-tax basis are accounted for as an adjustment to other comprehensive income in shareholders’ equity. Net unrealized pre-tax losses in the held-to-maturity portfolio, which are not accounted for in other comprehensive income, were $131.6 million at March 31, 2023, compared to $164.2 million at December 31, 2022. With approximately 33% of the investment portfolio in the held-to-maturity category, the recent volatility in interest rates does not have as much impact on other comprehensive income as if the entire portfolio were included in the available-for-sale category.

Equity securities, of which a portion consists of investments in various mutual funds held in grantor trusts formed in connection with a key officer and director deferred compensation plan, are recorded at fair value. Gains and losses due to fair value fluctuations on equity securities are included in net securities gains or losses. For those equity securities relating to the key officer and director deferred compensation plan, the corresponding change in the obligation to the employee 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 income statement in the provision for credit losses. Accrued interest receivable on held-to-maturity securities, which was $9.3 million and $9.5 million as of March 31, 2023 and December 31, 2022, 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.

Wesbanco uses prices from independent pricing services and, to a lesser extent, indicative (non-binding) quotes from independent brokers, to measure the fair value of its securities. Wesbanco validates prices received from pricing services or brokers using a variety of methods, including, but not limited to, comparison to secondary pricing services, corroboration of pricing by reference to other independent market data such as secondary broker quotes and relevant benchmark indices, review of pricing by personnel familiar with market liquidity and other market-related conditions, review of pricing service methodologies, review of independent auditor reports received from the pricing service regarding its internal controls, and through review of inputs and assumptions used in pricing certain securities thinly traded or with limited observable data points. The procedures in place provide management with a sufficient understanding of the valuation models, assumptions, inputs and pricing to reasonably measure the fair value of Wesbanco’s securities. For additional disclosure relating to fair value measurements, refer to Note 7, “Fair Value Measurement” in the Consolidated Financial Statements.

41

LOANS AND CREDIT RISK

Loans represent Wesbanco’s single largest balance sheet asset classification and the largest source of interest income. Business purpose loans consist of CRE loans and other C&I loans that are not secured by real estate. CRE loans are further segmented into land and construction loans, and loans for improved property. Consumer purpose loans consist of residential real estate loans, home equity lines of credit and other consumer loans. Loans held for sale generally consist of residential real estate loans originated for sale in the secondary market, but at times may also include other types of loans. The outstanding balance of each major category of the loan portfolio is summarized in Table 10.

The risk that borrowers will be unable or unwilling to repay their obligations and default on loans is inherent in all lending activities. Credit risk arises from many sources including general economic conditions, external events that impact businesses or industries, isolated events that impact a major employer, individual loss of employment or other personal hardships, as well as changes in interest rates or the value of collateral. Credit risk is also impacted by a concentration of exposure within a geographic market or to one or more borrowers, industries or collateral types. The primary goal in managing credit risk is to minimize the impact of default by an individual borrower or group of borrowers. Credit risk is managed through the initial underwriting process as well as through ongoing monitoring and administration of the portfolio that varies by the type of loan. The Bank’s credit policies establish standard underwriting guidelines for each type of loan and require an appropriate evaluation of the credit characteristics of each borrower. This evaluation includes the borrower’s primary source of repayment capacity; the adequacy of collateral, if any, to secure the loan; the potential value of personal guarantees as secondary sources of repayment; and other factors unique to each loan that may increase or mitigate its risk. Credit bureau scores are also considered when evaluating consumer purpose loans as well as guarantors of business purpose loans. However, the Bank does not periodically update credit bureau scores subsequent to when loans are made to determine changes in credit history.

Credit risk is mitigated for all types of loans by continuously monitoring delinquency levels and pursuing collection efforts at the earliest stage of delinquency. The Bank also monitors general economic conditions, including employment, housing activity and real estate values in its market. The Bank also periodically evaluates and changes its underwriting standards when warranted based on market conditions, the historical performance of a category of the portfolio, or other external factors. Credit risk is also regularly evaluated for the impact of adverse economic and other events that increase the risk of default and the potential loss in the event of default, to understand the impact on the Bank’s earnings and capital.

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 and personal guarantees.

(1)Loans are presented gross of the allowance for loan credit losses – loans and net of unearned income, credit valuation adjustments, and unamortized net deferred loan fee income and loan origination costs.

Total portfolio loans increased $186.0 million from December 31, 2022, and have increased $1.2 billion or 11.9% over the last twelve months. The increase over the last twelve months was driven by a 15.8% growth in improved property loans due to increased originations and declining prepayment rates, as well as a 27.4% increase in residential real estate balances, which also stems from declining prepayment rates and construction advances, despite efforts to sell more loans into the secondary market. Land and construction loans declined by 14.8% as a large number of construction projects were completed and subsequently transferred to improved property loans, which further increased those balances. Home equity loans have increased 16.7% and commercial and industrial loans have increased 0.4% over the 12 month period, while consumer loans have decreased 18.8%.

Total loan commitments of $4.9 billion, including loans approved but not closed, increased $295.7 million or 6.4% from December 31, 2022 due primarily to increased availabilities under lines of credit and loans approved but not closed. The average line utilization percentage for the commercial portfolio was 32.6% for the three months ended March 31, 2023 compared to 34.7% for the three months ended December 31, 2022.

The commercial portfolio is monitored for potential concentrations of credit risk by market, type of lending, CRE property type, C&I and owner-occupied CRE by industry, investment CRE dependence on common tenants and industries or property types that are similarly impacted by external factors.

42

Loans held for sale at both March 31, 2023 and December 31, 2022 are originated residential mortgages that are committed to be sold into the secondary market. Loans held for sale increased by $4.5 million or 54.2% from December 31, 2022 due to an increase in demand for fixed rate mortgages in the first quarter as mortgage rates declined slightly from December 31, 2022.

NON-PERFORMING ASSETS AND LOANS PAST DUE 90 DAYS OR MORE

Non-performing assets consist of non-accrual loans, other real estate acquired through or in lieu of foreclosure, bank premises held for sale, and repossessed automobiles acquired to satisfy defaulted consumer loans.

(1)Loans previously designated as TDRs that were also on non-accrual of $1.7 million are included in total non-accrual loans as of December 31, 2022.

(2)TDRs no longer exist as of January 1, 2023 because of Wesbanco's adoption of ASU 2022-02.

As of the adoption of ASU 2022-02, non-performing loans consist only of non-accrual loans. Non-performing loans in prior periods also include loans that were previously designated as TDRs. Non-performing loans decreased $2.2 million or 5.3%, from December 31, 2022 due to this change. Non-accrual loans increased $1.0 million or 2.7%. (Please see the Notes to the Consolidated Financial Statements for additional discussion).

Loans past due 30 days or more and accruing interest, excluding non-accruals, decreased $3.4 million or 16.2% from December 31, 2022. These loans continue to accrue interest because they are both well-secured and in the process of collection. Loans 90 days or more past due decreased $0.9 million and represented 0.04% and 0.05% of total portfolio loans at March 31, 2023 and December 31, 2022, respectively. Loans 30 to 89 days past due represented 0.12% of total portfolio loans at March 31, 2023 and 0.14% at December 31, 2022.

ALLOWANCE FOR CREDIT LOSSES - LOANS AND LOAN COMMITMENTS

As of March 31, 2023, the total allowance for credit losses – loans and commitments was $127.8 million, of which $118.7 million related to loans and $9.1 million related to loan commitments. The allowance for credit losses – loans was 1.09% of total portfolio loans as of March 31, 2023, compared to 1.10% as of December 31, 2022.

The allowance for credit losses– loans individually-evaluated decreased $0.8 million from December 31, 2022 to March 31, 2023. The population of individually-evaluated loans consisted primarily of one hotel loan and one office loan, with a total outstanding loan balance of $15.8 million. The allowance for loans collectively-evaluated increased from December 31, 2022 to March 31, 2023 by $1.7 million. The allowance for credit losses- loan commitments was $9.1 million at March 31, 2023 as compared to $8.4 million as of December 31, 2022, and is included in other liabilities on the Consolidated Balance Sheets.

The allowance for credit losses by loan category, presented in Note 4, “Loans and the Allowance for Credit Losses” of the Consolidated Financial Statements, summarizes the impact of changes in various factors that affect the allowance for loan losses in each segment of the portfolio. The allowance for credit losses under CECL is calculated utilizing the PD/LGD, 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, loan risk grades, portfolio mix, concentrations and loan growth. For the calculation as of March 31, 2023, 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 4.0%, and subsequently increase to an average of 4.5% over the remainder of the forecast period. Economic drivers of the quantitative model, including those for prepayment speed fluctuations, caused the allowance for credit losses - loans to increase from December 31, 2022 to March 31, 2023, by $0.9 million.

Criticized and classified loans were 1.60% of total portfolio loans at March 31, 2023, decreasing from 2.34% at December 31, 2022. Criticized and classified loans decreased from $250.5 million at December 31, 2022 to $173.8 million at March 31, 2023. The $76.7 million decline is primarily due to upgrades across the commercial loan portfolio. See Footnote 4, “Loans and the Allowance for Credit Losses” for more information.

Table 13 summarizes the allocation of the allowance for credit losses to each category of the loan portfolio.

Although the allowance for credit losses is allocated as described in Table 13, the total allowance is available to absorb actual losses in any category of the loan portfolio. However, differences between management’s estimation of probable losses and actual net charge-offs in subsequent periods for any category may necessitate future adjustments to the allowance for credit losses applicable to the category. Management believes the allowance for credit losses is appropriate to absorb expected losses at March 31, 2023.

Total deposits	$	12,873,196	$	13,131,090	$	(257,894	)		(2.0	)

Deposits, which represent Wesbanco’s primary source of funds, are offered in various account forms at various rates through Wesbanco’s 194 financial centers. The FDIC insures deposits up to $250,000 per account owner.

Total deposits decreased $257.9 million or 2.0% during the first three months of 2023. Savings deposits increased 1.6%, while money market deposit accounts and demand deposits decreased 3.9% and 3.0%, respectively. The overall decrease in transaction-based accounts is primarily attributable to inflationary pressures and rising costs across the country causing a decrease in personal savings. Deposit balances were also impacted by bonus and royalty payments for Marcellus and Utica shale gas payments from energy companies in Wesbanco’s southwestern Pennsylvania, eastern Ohio and northern West Virginia markets. In addition, Wesbanco also participates in the Insured Cash Sweep (ICS®) deposit program. ICS® reciprocal balances totaled $623.4 million at March 31, 2023 compared to $580.6 million at December 31, 2022. In addition, ICS® one-way buys totaled $100.0 million at March 31, 2023 compared to $0 at December 31, 2022.

Certificates of deposit were basically unchanged from December 31, 2022 to March 31, 2023. Wesbanco does not generally solicit brokered or other deposits out-of-market or over the internet, but does participate in the Certificate of Deposit Account Registry Services (CDARS®) program. CDARS® balances totaled $57.3 million in outstanding balances at March 31, 2023, of which $39.5 million represented one-way buys, compared to $21.0 million in total outstanding balances, none of which represented one-way buys, at December 31, 2022. Certificates of deposit greater than $250,000 were approximately $113.6 million at March 31, 2023 compared to $133.9 million at December 31, 2022. Certificates of deposit totaling approximately $548.4 million at March 31, 2023 with a cost of 0.93% are scheduled to mature within the next 12 months. Wesbanco intends to continue to focus on its core deposit strategies and improving its overall mix of transaction accounts to total deposits. From time to time, the Bank may offer special promotions or match competitor rates on certain certificates of deposit maturities and savings products based on competition, sales strategies, liquidity needs and wholesale borrowing costs.

Total	$	1,672,805	$	1,121,473	$	551,332			49.2

While borrowings are a significant source of funding for Wesbanco, they are less significant as compared to total deposits. FHLB borrowings increased $575.0 million from December 31, 2022 to March 31, 2023, as $1.3 billion in new advances were partially offset by $0.7 billion in maturities. The average cost of maturing FHLB advances was 4.72% during the first three months of 2023, compared to an average cost of 4.96% for new borrowings during the first three months of 2023.

Other short-term borrowings, which may consist of federal funds purchased, callable repurchase agreements, overnight sweep checking accounts, and borrowings on a revolving line of credit, were $111.2 million at March 31, 2023, compared to $135.1 million at December 31, 2022. There were no outstanding federal funds purchased at either March 31, 2023 or December 31, 2022.

Wesbanco renewed a revolving line of credit in August 2022, which is a senior obligation of the parent company, with another financial institution. This line of credit, with each advance accruing interest at the borrower selected rate of either an adjusted base rate, Daily SOFR, or Term SOFR, provides for aggregate unsecured borrowings of up to $30.0 million. There were no outstanding balances at either March 31, 2023 or December 31, 2022.

CAPITAL RESOURCES

Shareholders' equity increased $48.8 million or 2.0% from December 31, 2022, to $2.5 billion at March 31, 2023. The increase resulted from net income during the current three-month period of $42.3 million and a $28.0 million other comprehensive gain for the three months ended March 31, 2023, exceeding the declaration of common and preferred shareholder dividends totaling $20.6 million and $2.5 million, respectively. Wesbanco also increased its quarterly dividend rate $0.01 per quarter to $0.35 per share in November 2022, representing a 2.9% increase over the prior quarterly rate and a cumulative 150% increase since 2010.

Wesbanco did not purchase any shares of its common stock during the three-month period ended March 31, 2023 under the current share repurchase authorization. At March 31, 2023, the remaining shares authorized to be purchased under the last approved repurchase plan totaled 1,183,207 shares.

Regulatory guidelines require bank holding companies and commercial banks to maintain certain minimum capital ratios and define companies as “well capitalized” that sufficiently exceed the minimum ratios. At March 31, 2023, regulatory capital levels for both the Bank and Wesbanco were substantially greater than the minimum amounts needed to be considered “well capitalized” under the regulations. There are various legal limitations under federal and state laws that limit the payment of dividends from the Bank to Wesbanco. As of March 31, 2023, under FDIC regulations, Wesbanco could receive, without prior regulatory approval, a dividend of approximately $43.2 million from the Bank.

On March 26, 2020, regulators issued interim financial rule (“IFR”) “Regulatory Capital Rule: Revised Transition of the Current Expected Losses Methodology for Allowances” in response to the disrupted economic activity from the spread of COVID-19. The IFR provides financial institutions that adopt CECL during 2020 with the option to delay for two years the estimated impact of CECL on regulatory capital, followed by a three-year transition period to phase out the aggregate amount of the capital benefit provided by the initial two-year delay (“five-year transition”). Wesbanco adopted CECL effective January 1, 2020 and elected to implement the five-year transition. Regulatory capital levels without the capital benefit at March 31, 2023 for both the Bank and Wesbanco would have continued to be greater than the amounts needed to be considered “well capitalized,” as the capital benefit approximated 11 to 16 basis points for three of the four regulatory ratios, while total risk-based capital would have been slightly higher without the transition.

The following table summarizes risk-based capital amounts and ratios for Wesbanco and the Bank for the periods indicated:

LIQUIDITY RISK

Liquidity is defined as a financial institution’s capacity to meet its cash and collateral obligations at a reasonable cost. Liquidity risk is the risk that an institution’s financial condition or overall safety and soundness is adversely affected by an inability, or perceived inability, to meet its obligations. An institution’s obligations, and the funding sources to meet them, depend significantly on its business mix, balance sheet structure, and the cash flows of its on- and off-balance sheet obligations. Institutions confront various internal and external situations that can give rise to increased liquidity risk including funding mismatches, market constraints on funding sources, contingent liquidity events, changes in economic conditions, and exposure to credit, market, operation, legal and reputation risk. Wesbanco actively manages liquidity risk through its ability to provide adequate funds to meet changes in loan demand, unexpected outflows in deposits and other borrowings as well as to take advantage of market opportunities and meet operating cash needs. This is accomplished by maintaining liquid assets in the form of securities, sufficient borrowing capacity and a stable core deposit base. Liquidity is centrally monitored by Wesbanco’s Asset/Liability Committee (“ALCO”).

Wesbanco determines the degree of required liquidity by the relationship of total holdings of liquid assets to the possible need for funds to meet unexpected deposit losses and/or loan demands. The ability to quickly convert assets to cash at a minimal loss is a primary function of Wesbanco’s investment portfolio management. Wesbanco believes its cash flow from the loan portfolio, the investment portfolio, and other sources, adequately meet its liquidity requirements. Wesbanco’s net loans to assets ratio was 62.3% at March 31, 2023 and deposit balances funded 74.5% of assets.

The following table lists the sources of liquidity from assets at March 31, 2023 expected within the next year:

(unaudited, in thousands)
Cash and cash equivalents	$	597,503
Securities with a maturity date within the next year and callable securities		255,583
Projected payments and prepayments on mortgage-backed securities and collateralized mortgage obligations (1)		269,496
Loans held for sale		12,722
Accruing loans scheduled to mature		986,012
Normal loan repayments		1,180,335
Total sources of liquidity expected within the next year	$	3,301,651

(1)Projected prepayments are based on current prepayment speeds.

Deposit flows are another principal factor affecting overall Wesbanco liquidity. Deposits totaled $12.9 billion at March 31, 2023. Deposit flows are impacted by current interest rates, products and rates offered by Wesbanco versus various forms of competition, as well as customer behavior. Certificates of deposit scheduled to mature within one year totaled $548.4 million at March 31, 2023, with a weighted average cost of 0.93%, which includes jumbo regular certificates of deposit totaling $209.7 million with a weighted-average cost of 0.99%, and jumbo CDARS® deposits of $53.4 million with a weighted-average cost of 3.11%, which included $39.5 million of one-way buys.

Uninsured deposits, as reported for regulatory purposes, totaled $4.1 billion at March 31, 2023, which include $870.4 million of public funds deposits that are over the FDIC-insured limit. Wesbanco secures these public funds deposits by pledging investment securities with a market value at or above the deposit balance. Excluding these public funds, at March 31, 2023, uninsured deposits are $3.2 billion, or 25% of total deposits.

Wesbanco maintains a line of credit with the FHLB as an additional funding source. Available credit with the FHLB approximated $3.3 billion and $3.6 billion at March 31, 2023 and December 31, 2022, respectively. The FHLB requires securities to be specifically pledged to the FHLB and maintained in a FHLB-approved custodial arrangement if the member wishes to include such securities in the maximum borrowing capacity calculation. Wesbanco has elected not to specifically pledge to the FHLB otherwise unpledged securities. At March 31, 2023, the Bank had unpledged available-for-sale securities with an estimated fair value of $598.7 million, or 24.9% of the total available-for-sale portfolio. A portion of these securities could be sold for additional liquidity, or such securities could be pledged to secure additional FHLB borrowings. A significant portion of the portfolio is pledged to public deposit customers, as public deposit balances have increased significantly through the several acquisitions made since 2015. In addition, at March 31, 2023, the Bank had unpledged held-to-maturity securities with an estimated fair value of $844.1 million. Most of these securities are tax-exempt municipal securities, which can only be pledged in limited circumstances. Generally, these securities cannot be sold without tainting the remainder of the held-to-maturity portfolio. If tainting occurs, all remaining securities with the held-to-maturity designation would be required to be reclassified as available-for-sale, and the held-to-maturity designation would not be available to Wesbanco for a period of time.

Wesbanco participates in the Federal Reserve Bank’s Borrower-in-Custody Program (“BIC”) whereby Wesbanco pledges certain consumer loans as collateral for borrowings. Wesbanco did not have any BIC borrowings outstanding at March 31, 2023. Alternative funding sources may include the utilization of existing overnight lines of credit with third party banks totaling $235.0 million, none of which was outstanding at March 31, 2023, along with seeking other lines of credit, borrowings under repurchase agreement lines, increasing deposit rates to attract additional funds, accessing brokered deposits, or selling securities available-for-sale or certain types of loans. In addition, in March 2023, the Federal Reserve announced that it would make available additional funding to eligible depository institutions through the creation of a new Bank Term Funding Program ("BTFP"). The BTFP would offer loans of up to one year in length to eligible depository institutions that pledge U.S. Treasuries, agency debt and mortgage-backed securities, or other qualifying assets as collateral. As of March 31, 2023, Wesbanco has not utilized the BTFP for funding, but does have $583.9 million in par value of qualifying investment securities that could be used to access funds from the program.

Other short-term borrowings of $111.2 million at March 31, 2023 consisted of callable repurchase agreements and overnight sweep checking accounts for large commercial customers. Other short-term borrowings may also include federal funds purchased. The overnight sweep checking accounts require U.S. Government securities to be pledged equal to or greater than the average deposit balance in the related customer accounts.

48

The principal sources of parent company liquidity are dividends from the Bank, $276.1 million in cash on hand, and a $30.0 million revolving line of credit with another bank, which did not have an outstanding balance at March 31, 2023. Wesbanco is in compliance with all applicable loan covenants. There are various legal limitations under federal and state laws that limit the payment of dividends from the Bank to the parent company. As of March 31, 2023, under FDIC and State of West Virginia regulations, Wesbanco could receive, without prior regulatory approval, dividends of approximately $43.3 million from the Bank. Management believes these are appropriate levels of cash for the parent company given the current environment. Management continuously monitors the adequacy of parent company cash levels and sources of liquidity through the use of metrics that relate current cash levels to historical and forecasted cash inflows and outflows.

Wesbanco had outstanding commitments to extend credit in the ordinary course of business approximating $4.9 billion and $4.6 billion at March 31, 2023 and December 31, 2022, respectively. On a historical basis, only a portion of these commitments will result in an outflow of funds. Please refer to Note 10, “Commitments and Contingent Liabilities” of the Consolidated Financial Statements and the “Loans and Credit Risk” section of this MD&A for additional information.

Federal financial regulatory agencies have previously issued guidance to provide for sound practices for managing funding and liquidity risk and strengthening liquidity risk management practices. Wesbanco maintains a comprehensive management process for identifying, measuring, monitoring, and controlling liquidity risk, which is fully integrated into its risk management process. Management believes Wesbanco has sufficient current liquidity to meet current obligations to borrowers, depositors and others and that Wesbanco’s current liquidity risk management policies and procedures, as periodically reviewed and adjusted, adequately address this guidance.

LIBOR TRANSITION

LIBOR is a widely used short-term reference interest rate benchmark for variable rate loans and securities, borrowings, and interest rate hedge/swap transactions. In July 2017, the U.K. Financial Conduct Authority (“FCA”) announced the discontinuation of LIBOR after certain banks provided purported interest rate figures which did not truly reflect the rate at which they could borrow. In addition to FCA, as early as 2014, financial institution regulators and the Federal Financial Institutions Examination Council (“FFIEC”) began to work to develop a uniform approach to the phase-out of LIBOR because the continued reliance on LIBOR could present systematic risk to financial institutions. The Board of Governors of the Federal Reserve System and the Federal Reserve Bank of New York convened the Alternative Reference Rates Committee (“AARC”) to identify alternative reference rates to LIBOR. The AARC released consultations on contractual fallback language to prepare for the transition away for LIBOR and on June 22, 2017, identified SOFR as the recommended alternative to LIBOR.

On July 1, 2020, the FFIEC issued a Joint Statement on Managing the LIBOR Transition to further explain that new financial contracts should either utilize a reference rate other than LIBOR or have robust fallback language that defines an alternative reference rate after LIBOR’s discontinuation. The FFIEC statement encouraged supervised financial institutions to continue their efforts to prepare for the change and address the risks associated with the LIBOR transition.

On November 6, 2020, the Board of Governors of the Federal Reserve System, the Office of the Comptroller of the Currency, and the Federal Deposit Insurance Corporation (collectively, the “Agencies”) issued a statement providing that a financial institution may use any reference rate for its loans that the financial institution determines to be appropriate for its funding model and customer needs.

Thereafter, on November 30, 2020, the Agencies issued an additional joint statement encouraging financial institutions to continue to transition away from LIBOR as soon as practicable, but no later than December 31, 2021. Given the risks associated with the use of LIBOR, the Agencies stated that entering into new contracts that use LIBOR as a reference rate after December 31, 2021, would create safety and soundness risks.

On March 5, 2021, the U.K. FCA and Intercontinental Exchange (“ICE”) Benchmark Administration announced that the publication of the overnight, as well as, the one, three, six, and twelve month LIBOR rates will continue through June 30, 2023, which will provide additional time to wind down or renegotiate existing contracts that reference LIBOR.

On October 20, 2021, the Agencies with the Consumer Financial Protection Bureau, National Credit Union Administration, and State Bank and Credit Union Regulators, issued an additional Joint Statement on Managing the LIBOR Transition to once again emphasize the expectation that supervised institutions with LIBOR exposure continue to progress toward an orderly transition away from LIBOR. The statement confirmed that entering into new contracts, including derivatives that use LIBOR as a reference rate after December 31, 2021, would create safety and soundness risks, including litigation, operational, and consumer protection risks.

On March 15, 2022, President Biden signed the Adjustable Interest Rate (LIBOR) Act into law (the “LIBOR Act”). The LIBOR Act provides a clear and uniform federal solution for transitioning legacy contracts that either lack or contain insufficient contractual provisions addressing the permanent cessation of LIBOR by providing for the transition from LIBOR to a replacement rate and avoiding related litigation.

49

On December 16, 2022, the Federal Reserve Board adopted a final rule that implements the Adjustable Interest Rate (LIBOR) Act by identifying benchmark rates based on SOFR that will replace LIBOR in certain financial contracts after June 30, 2023. The final rule is substantially similar to the proposal with certain clarifying changes made in response to comments.

•For a LIBOR contract that is a derivative transaction, the “Fallback Rate (SOFR)” as defined in the 2020 IBOR Fallbacks Protocol published by the International Swaps and Derivatives Association (ISDA protocol), which incorporates the statutorily prescribed tenor spread adjustment.

•For a LIBOR contract that is an FHFA-regulated-entity contract:

•For Federal Home Loan Bank advances, the “Fallback Rate (SOFR)” as defined in the ISDA protocol; and

•For all other FHFA-regulated-entity contracts, SOFR (in place of overnight LIBOR) or 30-day compounded average SOFR published by FRBNY (“30-day Average SOFR,” in place of one-, three-, six-, or 12-month LIBOR), plus the applicable statutorily prescribed tenor spread adjustment.

•For a LIBOR contract that is a FFELP ABS, either (i) 30-day Average SOFR (for one-, six-, and 12-month LIBOR) or (ii) 90-day compounded average SOFR published by FRBNY (for three-month LIBOR), plus the applicable statutorily prescribed tenor spread adjustment.

•For all other LIBOR contracts, including consumer loans, SOFR (in place of overnight LIBOR) or term SOFR published by CME Group Benchmark Administration, Ltd. (in place of one-, three-, six-, or 12-month LIBOR), plus the statutorily prescribed tenor spread adjustment.

As early as 2018, in anticipation of the potential discontinuance of LIBOR, Wesbanco established a LIBOR transition committee to effectively manage the Company’s transition away from LIBOR in two phases. The first phase included adding additional fallback language to loan documents to allow Wesbanco to replace LIBOR with an equivalent rate index plus the margin to ensure the resulting interest rate is the same as it previously was using LIBOR. Also, as part of the first phase, Wesbanco began quoting to the Treasury Rate published by the Federal Reserve Board instead of the ICE LIBOR Swap Index (which is tied to LIBOR) when repricing certain term loans and originating new loans. The second phase consists of working to continue to transition existing adjustable-rate loans that fluctuate monthly or periodically that are tied to LIBOR or the ICE LIBOR Swap Index. Wesbanco is tracking the dollar amount and number of loans tied to LIBOR or the ICE LIBOR Swap Index, monitoring current industry trends, and working with legal counsel to ensure the smooth transition away from LIBOR. As of March 31, 2023, Wesbanco had a total of $1.3 billion in loans tied to either LIBOR or the ICE LIBOR Swap index, of which $1.2 billion have a maturity date after June 30, 2023. As referenced above, the U.K. FCA and ICE Benchmark Administration has extended the date of publication of certain tenors of LIBOR through June 30, 2023, giving existing LIBOR based contracts time to mature. However, in compliance with and based upon the Agencies Joint Statements referenced above, Wesbanco has not offered LIBOR for new contracts after December 31, 2021. Accordingly, Wesbanco has initially chosen the 1M Term SOFR, which is published by the Chicago Mercantile Exchange, as an alternative replacement rate for LIBOR. Wesbanco may also continue to utilize the Wall Street Journal Prime Rate, the Treasury Rates, and other indexes as part of its lending program. At a date in the future, prior to the cessation of the publication of the one month LIBOR, Wesbanco will transition all remaining LIBOR based loans to the replacement index after notification to the impacted borrowers. This transition will be aided by the passage of the LIBOR Act. With respect to its back-to-back swap program, Wesbanco worked with its swap counterparty customers to institute and accept the International Swaps and Derivatives Association 2020 Interbank Offered Rate Fallbacks Protocol to address LIBOR cessation in swap transactions. Moreover, Wesbanco chose 1M Term SOFR as its replacement index for new loans in the bank’s back-to-back swap program, beginning on January 1, 2022.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

The disclosures set forth in this item are qualified by the section captioned “Forward-Looking Statements” included in Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations of this report.

MARKET RISK

The primary objective of the ALCO is to maximize net interest income within established policy parameters. This objective is accomplished through the management of balance sheet composition, market risk exposures arising from changing economic conditions and liquidity risk.

Market risk is defined as the risk of loss due to adverse changes in the fair value of financial instruments resulting from fluctuations in interest rates and bond prices. Management considers interest rate risk to be Wesbanco’s most significant market risk. Interest rate risk is the exposure to adverse changes in net interest income due to changes in interest rates. The consistency of Wesbanco’s net interest income is largely dependent on effective management of interest rate risk. As interest rates change in the market, rates earned on interest rate-sensitive assets and rates paid on interest rate-sensitive liabilities do not necessarily move concurrently. Differing rate sensitivities may arise because fixed rate assets and liabilities may not have the same maturities, or because variable rate assets and liabilities differ in the timing and/or the percentage of rate changes.

Wesbanco’s ALCO is an executive management committee with Board representation, responsible for monitoring and managing interest rate risk within approved policy limits, utilizing earnings sensitivity simulation and economic value-at-risk models. These models are highly dependent on various assumptions, which change regularly as the balance sheet and market interest rates change. The key assumptions and strategies employed are analyzed, reviewed and documented at least quarterly by the ALCO.

The earnings sensitivity simulation model projects changes in net interest income resulting from the effects of changes in interest rates. Forecasting changes in net interest income requires management to make certain assumptions regarding loan and security prepayment rates, call dates, changes to deposit product betas and non-maturity deposit decay rates, which may not necessarily reflect the manner in which actual cash flows, yields, and costs respond to changes in market interest rates. Assumptions are based on historical experience, current market rates and economic forecasts, and are internally back-tested and periodically reviewed by a third-party consultant. The net interest income sensitivity results presented in Table 1, “Net Interest Income Sensitivity,” assumes that the balance sheet composition of interest sensitive assets and liabilities existing at the end of the period remains constant over the period being measured and also assumes that a particular change in interest rates is reflected uniformly across the yield curve, regardless of the duration of the maturity or re-pricing of specific assets and liabilities. Since the assumptions used in the model relative to changes in interest rates are uncertain, the simulation analysis may not be indicative of actual results. In addition, this analysis does not consider actions that management might employ in response to changes in interest rates, as well as changes in earning asset and costing liability balances.

Interest rate risk policy limits are determined by measuring the anticipated change in net interest income over a twelve-month period, assuming immediate and sustained market interest rate increases of 100 - 200 basis points and decreases of 100 - 400 basis points across the entire yield curve, as compared to a stable rate environment or base model. Wesbanco’s current policy limits this exposure for the noted interest rate changes to a reduction of between 7.5% - 20%, or less, of net interest income from the stable rate base model over a twelve-month period. The table below indicates Wesbanco’s interest rate sensitivity at March 31, 2023 and December 31, 2022, assuming the above-noted interest rate changes, as compared to a base model.

TABLE 1. NET INTEREST INCOME SENSITIVITY

Immediate Change in	Percentage Change in
Interest Rates	Net Interest Income from Base over One Year		ALCO
(basis points)	March 31, 2023	December 31, 2022	Guidelines
+200	5.0%	5.6%	(10.0%)
+100	2.5%	2.8%	(7.5%)
-100	(3.1%)	(4.4%)	(7.5%)
-200	(7.3%)	(9.8%)	(10.0%)
-300	(12.2%)	(15.6%)	(15.0%)
-400	(17.8%)	N/A	(20.0%)

Adjustments to relative sensitivities are due to the impact of the current lower rate and yield curve environment on base case net interest income and the related calculation of parallel rate shock changes in rising and falling rate scenarios. Additional differences typically result from changes in the various earning assets and costing liabilities mix and growth rates, as well as adjustments for various modeling assumptions. Generally, deposit betas utilized in modeling are estimated at more conservative percentages for various rate scenarios than has been the Bank’s historical experience, as a result of both competitive factors in our markets and as public funds and institutional contract terms are renewed. Deposit betas, decay rates and loan prepayment speeds are adjusted periodically in our models for non-maturity deposits and loans. Indicated model asset sensitivity in rising rate scenarios may be less than anticipated due to slower prepayment speeds, rate floors, below forecast new loan yields, spread compression between new asset yields and funding costs, mortgage-related extension risk and other factors. In a decreasing rate environment, asset sensitivity may have greater impact on the margin than currently modeled as prepayment speeds increase, customers refinance or request rate reductions on existing loans, estimated deposit betas do not perform as modeled, or for other reasons.

51

In addition to the aforementioned parallel rate shock earnings sensitivity simulation model, the ALCO also reviews a “dynamic” forecast scenario to project net interest income over a rolling two-year time period. This forecast is updated at least quarterly, incorporating revisions and updated assumptions into the model for estimated loan and deposit growth, expected balance sheet re-mixing strategies, changes in forecasted rates for various maturities, competitive market spreads for various products and other assumptions. Such modeling is directionally consistent with typical parallel rate shock scenarios, and it assists in predicting changes in forecasted outcomes as well as suggesting potential adjustments to management plans to assist in achieving earnings goals.

Wesbanco also periodically measures the economic value of equity (“EVE”), which is defined as the market value of tangible equity in various rate scenarios. Generally, changes in the economic value of equity relate to changes in various assets and liabilities, changes in the yield curve, as well as changes in loan prepayment speeds and deposit decay rates. The following table presents these results and Wesbanco’s policy limits as of March 31, 2023 and December 31, 2022. Changes in EVE sensitivity since year-end 2022 relate to the change in market interest rates and their impact upon the fair values of earning assets and costing liabilities.

Immediate Change in	Percentage Change in
Interest Rates	Economic Value of Equity from Base over One Year		ALCO
(basis points)	March 31, 2023	December 31, 2022	Guidelines
+200	(3.4%)	(4.3%)	(20.0%)
+100	(1.3%)	(1.8%)	(10.0%)
-100	(1.6%)	(0.8%)	(10.0%)
-200	(7.2%)	(7.9%)	(20.0%)
-300	(15.6%)	(17.5%)	(30.0%)
-400	(26.0%)	N/A	(40.0%)

The Bank has significant additional borrowing capacity with the FHLB of Pittsburgh, the Federal Reserve Bank of Cleveland and various correspondent banks, and may utilize these funding sources or interest rate swap strategies as necessary to lengthen liabilities, offset mismatches in various asset maturities and manage liquidity. CDARS® and ICS® deposits also may be utilized for similar purposes for certain customers seeking higher-yielding instruments or maintaining deposit levels below FDIC insurance limits. Significant balance sheet strategies to assist in managing the net interest margin in the current interest rate environment include:

•increasing total loans, particularly commercial and home equity loans that have variable or adjustable features;

•selling a percentage of longer-term residential mortgage loan production into the secondary market;

•growing demand deposit account types to increase the relative portion of these account types to total deposits;

•employing back-to-back loan swaps for certain commercial loan customers desiring a term fixed-rate loan equivalent, with the Bank receiving a variable rate;

•adjusting terms for FHLB short-term maturing borrowings to balance asset/liability mismatches; or paying them off with excess liquidity;

•using CDARS® and ICS® deposit programs to manage funding needs and overall liability mix; and

•adjusting the size, mix or duration of the investment portfolio as part of liquidity and balance sheet management strategies.

Management is aware of the significant effect that inflation or deflation has upon interest rates and ultimately upon financial performance. Wesbanco’s ability to cope with inflation or deflation is best determined by analyzing its capability to respond to changing market interest rates, as well as its ability to manage the various elements of non-interest income and expense during periods of increasing or decreasing inflation or deflation. Wesbanco monitors the level and mix of interest-rate sensitive assets and liabilities through ALCO in order to reduce the impact of inflation or deflation on net interest income. Management also controls the effects of inflation or deflation by conducting periodic reviews of the prices, costs and terms of its various products and services, as well as competitive factors, by approving new products and services or adjusting the terms and availability of existing products and services for both Wesbanco as well as its business loan customers. Over the last few quarters, inflation has been trending higher and has impacted the cost of labor and purchased goods and services. Wesbanco is also monitoring the potential impact that inflation is having on single family home construction and multifamily properties as proposed rental rate caps and controls are put in place in areas across Wesbanco’s footprint.

ITEM 4. CONTROLS AND PROCEDURES

EVALUATION OF DISCLOSURE CONTROLS AND PROCEDURES— Wesbanco’s Chief Executive Officer (“CEO”) and Chief Financial Officer (“CFO”) have concluded that Wesbanco’s disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended), based on their evaluation of these controls and procedures as of the end of the period covered by this Form 10-Q, are effective to ensure that information required to be disclosed by Wesbanco in the reports it files under the Securities Exchange Act of 1934, as amended, is recorded, processed, summarized and reported within the time periods specified in the rules and forms of the SEC and that such information is accumulated and communicated to Wesbanco’s management, including its principal executive officer and principal financial officer, as appropriate to allow timely decisions regarding required disclosure.

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

CHANGES IN INTERNAL CONTROLS— There were no changes in Wesbanco's internal control over financial reporting that occurred during our fiscal quarter ended March 31, 2023 as required to be reported by paragraph (d) of Rules 13a-15 and 15d-15 under the Securities Exchange Act of 1934, that materially affected, or are reasonably likely to materially affect, the Company's internal control over financial reporting.

53

PART II – OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

Wesbanco is involved in various lawsuits, claims, investigations and proceedings, which arise in the ordinary course of business. While any litigation contains an element of uncertainty, Wesbanco does not believe that a material loss related to such proceedings or claims pending or known to be threatened is reasonably possible.

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”) 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, 2022.

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 2022 Annual Report on Form 10-K filed with the Securities and Exchange Commission, 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. Certain prior period amounts have been reclassified to conform to the current period presentation. Such reclassifications had no impact on Wesbanco’s net income and shareholders’ equity. Results of operations for interim periods are not necessarily indicative of the results of operations that may be expected for a full year.

Modifications for Borrowers Experiencing Financial Difficulty (“MBEFD”) — A modification of a loan for borrowers experiencing financial difficulty is applicable when the loan modification results in a direct change in the timing or amount of contractual cash flows. The most common modifications provided to borrowers experiencing financial difficulty are expected to occur in the form of principal forgiveness, interest rate reductions, other-than-insignificant-payment delays, or term extensions under ASC 310-10-50-39. Upon Wesbanco's adoption of Accounting Standards Update (“ASU”) 2022-02 on January 1, 2023, Troubled Debt Restructuring ("TDR") accounting was prospectively discontinued and economic concessions for modifications occurring on or after the adoption date are no longer measured. This accounting also results in the elimination of any existing economic concession related to a loan that was previously designated as a TDR if such loan is restructured on or after January 1, 2023. Due to the elimination of economic concessions under ASU 2022-02, the standard may result in modified loans being subject to the new disclosures that would have not been considered concessions and not treated as TDRs.

When determining whether a debtor is experiencing financial difficulties, consideration is given to any known default on any of its debt or whether it is probable that the debtor would be in payment default in the foreseeable future without the modification. Other indicators of financial difficulty include whether the debtor has declared or is in the process of declaring bankruptcy, the debtor’s ability to continue as a going concern, or the debtor’s projected cash flow to service its debt (including principal & interest) in accordance with the contractual terms for the foreseeable future, without a modification. If the payment of principal at original maturity is primarily dependent on the value of collateral, the current value of that collateral is considered in determining whether the principal will be paid.

The modification of a loan does not increase the allowance or provision for credit losses unless the loan is extended, or the loans are commercial loans that are individually evaluated for impairment, in which case a specific reserve is established pursuant to GAAP. Portfolio segment loss history is the primary factor for establishing the allowance for residential real estate, home equity and consumer MBEFDs.

Non-accrual loans that are restructured remain on non-accrual, but may move to accrual status after they have performed according to the restructured terms for a period of time. MBEFDs on accrual status generally remain on accrual as long as they continue to perform in accordance with their modified terms. MBEFDs may also be placed on non-accrual if they do not perform in accordance with the restructured terms. Loans may be removed from MBEFD status after they have performed according to the renegotiated terms for a period of time.

Recent accounting pronouncements—The Financial Accounting Standards Board (“FASB”) issued Accounting Standards Updates (“ASU”) as noted below.

ASU 2023-02 – Investments Equity Method and Joint Ventures (Topic 323)

In March 2023, the FASB issued ASU 2023-02, Investments—Equity Method and Joint Ventures (Topic 323): Accounting for Investments in Tax Credit Structures Using the Proportional Amortization Method. ASU 2023-02 allows reporting entities to elect to account for qualifying tax equity investments using the proportional amortization method, regardless of the program giving rise to the related income tax credits. The ASU’s amendments “remove the specialized guidance for [low-income-housing tax credit] investments that are not accounted for using the proportional amortization method and instead require that those LIHTC investments be accounted for using the guidance in other [GAAP].” For Wesbanco, the amendments are effective for fiscal years beginning after December 15, 2023, including interim periods within those fiscal years. The adoption of this pronouncement is not expected to have a material impact on the Consolidated Financial Statements.

ASU 2023-01 - Leases (Topic 842): Common Control Arrangements

In March 2023, the FASB issued ASU 2023-01, Leases (Topic 842): Common Control Arrangements. ASU 2023-01 amends certain provisions of ASC 842 that apply to arrangements between related parties under common control. Additionally, ASU 2023-01 amends the accounting for leasehold improvements in common-control arrangements for all entities. For Wesbanco, the amendments are effective for fiscal years beginning after December 15, 2023, including interim periods within those fiscal years. Early adoption is permitted in any annual or interim period as of the beginning of the related fiscal year. The adoption of this pronouncement is not expected to have a material impact on the Consolidated Financial Statements.

ASU 2022-04 Liabilities – Supplier Finance Programs (Sub-topic 405-50)

In September 2022, the FASB issued ASU 2022-04, “Liabilities—Supplier Finance Programs (Subtopic 405-50).” The amendments in this ASU require that a buyer in a supplier finance program disclose sufficient information about the program to allow a user of financial statements to understand the program’s nature, activity during the period, changes from period to period, and potential magnitude. To achieve that objective, the buyer should disclose qualitative and quantitative information about its supplier finance programs. For Wesbanco, this update was effective beginning on January 1, 2023, except for the amendment on rollforward information, which is effective for fiscal years beginning after December 15, 2023. The adoption of this full pronouncement is not expected to have a material impact on the Consolidated Financial Statements.

ASU 2022-03 Fair Value Measurement (Topic 820)

In June 2022, the FASB issued ASU 2022-03, "Fair Value Measurement (Topic 820).” The amendments in this ASU clarify that a contractual restriction on the sale of an equity security is not considered part of the unit of account of the equity security, and therefore, is not considered in measuring fair value. Furthermore, the amendments to this ASU clarify that an entity cannot, as a separate unit of account, recognize and measure a contractual sale restriction. The update to this ASU requires the following disclosures for equity securities: (1) The fair value of equity securities subject to contractual sale restrictions reflected in the balance sheet; (2) The nature and remaining duration of the restriction(s) and; (3) The circumstances that could cause a lapse in the restriction(s). The amendments in this Update are effective for fiscal years beginning after December 15, 2023, and interim periods within those fiscal years. Wesbanco is currently assessing the impact of ASU 2022-03 on its Consolidated Financial Statements.

ASU 2022-02 Financial Instruments - Credit Losses (Topic 326)

In March 2022, the FASB issued ASU 2022-02, "Financial Instruments - Credit Losses (Topic 326)." The amendments in this ASU eliminate the accounting guidance for TDRs by creditors in Subtopic 310-40, "Receivables - Troubled Debt Restructurings by Creditors," while enhancing disclosure requirements for certain loan refinancings and restructurings by creditors when a borrower is experiencing financial difficulty. Specifically, rather than applying the recognition and measurement guidance for TDRs, an entity must apply the loan refinancing and restructuring guidance in paragraphs 310-20-35-9 through 35-11 to determine whether a modification results in a new loan or a continuation of an existing loan. In addition, for public business entities, the amendments in this Update require that an entity disclose current-period gross writeoffs by year of origination for financing receivables and net investments in leases within the scope of Subtopic 326-20, "Financial Instruments - Credit Losses - Measured at Amortized Cost." For Wesbanco, this update was effective beginning on January 1, 2023. The adoption of this pronouncement did not have a material impact on the Consolidated Financial Statements. For the additional disclosure requirements in this ASU, please refer to Footnote 4, "Loans and the Allowance for Credit Losses."

ASU 2020-04, ASU 2021-01 and ASU 2022-06 Reference Rate Reform (Topic 848)

In March 2020, the FASB issued ASU 2020-04, “Reference Rate Reform (Topic 848).” This ASU provided temporary, optional guidance to ease the potential burden in accounting for, or recognizing the effects of, the transition away from the London Interbank Offered Rate ("LIBOR") or other reference rate expected to be discontinued on financial reporting. The ASU also provides optional expedients for contract modifications that replace a reference rate affected by reference rate reform. The guidance is effective as of March 12, 2020 through December 31, 2022, and can be adopted at any time during this period. In January 2021, the FASB issued ASU 2021-01, “Reference Rate Reform (Topic 848): Scope.” This ASU refines the scope of Topic 848 and addresses questions about whether Topic 848 can be applied to derivative instruments that do not reference a rate that is expected to be discontinued, but that use an interest rate for margining, discounting or contract price alignment that is expected to be modified as a result of reference rate reform. ASU 2021-01 is effective upon issuance through December 31, 2024, and can be adopted at any time during this period. Wesbanco has not offered LIBOR for any new contracts after December 31, 2021. Wesbanco has chosen the One Month Term Secured Overnight Financing Rate ("1M Term SOFR") as its alternative replacement rate for LIBOR on both back-to-back swaps and on one-month variable loans. A transition plan was implemented in 2021 to identify and modify Wesbanco's loans and other financial instruments with attributes that are either directly or indirectly influenced by LIBOR, and Wesbanco continues to assess the impact of adopting the new guidance on the consolidated financial statements on an ongoing basis, with no material impacts expected at this time. In December 2022, the FASB issued ASU 2022-06, “Reference Rate Reform (Topic 848): Deferral of the Sunset Date of Topic 848.” In the Update, the Board decided to defer the sunset date of Topic 848 to December 31, 2024, to permit entities to apply the guidance in Topic 848 through the expected cessation date of USD LIBOR. In the Board’s view, that time frame would have been sufficient to provide flexibility for additional unforeseen changes to the timeline of USD LIBOR cessation and to accommodate global interbank offered rate (IBOR) transition. The update is not expected to have a material impact on Wesbanco’s Consolidated Financial Statements.

Earnings Per Common Share

NOTE 2. EARNINGS PER COMMON SHARE

Earnings per common share are calculated as follows:

	For the Three Months Ended March 31,
(unaudited, in thousands, except shares and per share amounts)	2023		2022
Numerator for both basic and diluted earnings per common share:
Net income available to common shareholders	$	39,810	$	41,593
Denominator:
Total average basic common shares outstanding		59,217,711		61,445,399
Effect of dilutive stock options and other stock compensation		157,342		147,966

Earnings per common share - basic	$	0.67	$	0.68
Earnings per common share - diluted	$	0.67	$	0.68

As of March 31, 2023 and 2022, 483,011 and 384,761 options to purchase shares were not included in the diluted share computation for the three months ended March 31, 2023 and 2022, 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, 2023, an aggregate of 42,624 contingently issuable shares were estimated to be awarded under the 2022 and 2021 total shareholder return ("TSR") plans, as stock performance targets had been met as of such date and therefore those shares were included in the diluted calculation. No shares related to the 2023 plan were included because the effect would be antidilutive. As of March 31, 2022, 16,224 contingently issuable shares were estimated to be awarded under the 2022 TSR plan, as stock performance targets had been met as of such date and therefore those shares were included in the diluted calculation. As of March 31, 2022, the shares related to the 2021 and 2020 TSR plans were not included in the calculation because the effect would be antidilutive.

In addition, performance-based restricted stock ("PBRS") compensation totaling 61,510 and 61,267 shares were estimated to be awarded as of March 31, 2023 and March 31, 2022, respectively.

(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, 2023 and December 31, 2022, respectively.

At March 31, 2023 and December 31, 2022, 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 $9.3 million 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 $11.8 million and $11.5 million at March 31, 2023 and December 31, 2022, 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, 2023. 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 fair value of $2.1 billion at March 31, 2023 and December 31, 2022, respectively, were pledged as security for public and trust funds, and securities sold under agreements to repurchase. Proceeds from the sale of available-for-sale securities for the three months ended March 31, 2023 and 2022 totaled $20.5 million and $0 million, respectively. Net unrealized losses on available-for-sale securities included in accumulated other comprehensive income, net of tax, as of March 31, 2023 and December 31, 2022 were $233.9 million and $261.8 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, 2023 and 2022, respectively. All gains and losses presented in the table below are included in the net securities gains (losses) line item of the 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 income statement in the provision for credit losses. Accrued interest receivable on held-to-maturity securities, which was $9.3 million and $9.5 million as of March 31, 2023 and December 31, 2022, 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, 2023 and 2022:

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 Federal Home Loan Bank (“FHLB”) of Pittsburgh stock totaling $59.2 million and $36.2 million at March 31, 2023 and December 31, 2022, 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 $10.3 million and $9.6 million at March 31, 2023 and December 31, 2022, respectively. The un-accreted discount on purchased loans from acquisitions was $16.7 million at March 31, 2023 and $18.0 million at December 31, 2022.

As of March 31, 2023, accrued interest receivable for loans was $53.0 million. 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, Wesbanco does have a $0.2 million reserve on the accrued interest related to loan modifications allowed under the Coronavirus Aid, Relief and Economic Security ("CARES") Act due to the timing and nature of these modifications. As of March 31, 2023, accrued interest related to COVID-19 loan modifications as permitted under the CARES Act was $16.7 million.

The following tables summarize changes in the allowance for credit losses applicable to each category of the loan portfolio:

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.

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 $20.4 million at March 31, 2023 and $24.8 million at December 31, 2022, of which $2.6 million and $5.9 million were accruing, for each period, respectively. These loans are not included in the tables above. In addition, $30.3 million and $25.0 million of unfunded commercial loan commitments are also not included in the tables above at March 31, 2023 and December 31, 2022, respectively.

Derivatives and Hedging Activities

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Derivatives and Hedging Activities

NOTE 5. 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 Bank's assets and liabilities 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, 2023 and December 31, 2022, Wesbanco had 169 and 159 customer interest rate swaps and caps with an aggregate notional amount of $1.1 billion and $0.9 billion, respectively, related to this program. Wesbanco recognized income for the related swap and cap fees of $1.8 million and $0.2 million for the three months ended March 31, 2023 and 2022, 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, 2023 and December 31, 2022, Wesbanco had 17 and 16 risk participation-in agreements with an aggregate notional amount of $195.1 million and $187.8 million, respectively. As of March 31, 2023 and December 31, 2022, Wesbanco had one risk participation-out agreement with an aggregate notional amount of $9.5 million and $9.6 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 $40.0 million and $14.5 million at March 31, 2023 and December 31, 2022, 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, 2023 and December 31, 2022:

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. If Wesbanco had breached any of these provisions at March 31, 2023, 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. In certain market situations, Wesbanco can also request collateral from the derivative counterparties. Due to the recent rise in interest rates, as of March 31, 2023, Wesbanco is holding collateral from various derivative counterparties with a market value of $27.6 million.

Fair Value Measurement

NOTE 7. 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.

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.

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 table 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, 2023 and December 31, 2022:

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 significant transfers between level 1, 2 or 3 for the three months ended March 31, 2023 or for the year ended December 31, 2022.

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.

Net loans: Fair values for loans are estimated 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 10. 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 $9.1 million and $8.4 million at March 31, 2023 and December 31, 2022, 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 $0.3 million and $0.2 million as of March 31, 2023 and December 31, 2022, respectively.

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:

	March 31,		December 31,
(unaudited, in thousands)	2023		2022
Lines of credit	$	3,938,353	$	3,806,398
Loans approved but not closed		548,801		398,204
Overdraft limits		391,322		380,143
Letters of credit		32,317		30,362
Contingent obligations and other guarantees		21,682		30,782

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 11. BUSINESS SEGMENTS

Wesbanco operates two reportable segments: community banking and trust and investment services. Wesbanco’s community banking segment offers services traditionally offered by full-service commercial banks, including commercial demand, individual demand and time deposit accounts, as well as commercial, mortgage and individual installment loans, and certain non-traditional offerings, such as insurance and securities brokerage services. The trust and investment services segment offers trust services as well as various alternative investment products including mutual funds. The market value of assets managed or held in custody by the trust and investment services segment was approximately $5.0 billion and $5.4 billion at March 31, 2023 and 2022, respectively. These assets are held by Wesbanco in fiduciary or agency capacities for their customers and therefore are not included as assets on Wesbanco’s Consolidated Balance Sheets.

Summary of Significant Accounting Policies (Policies)

3 Months Ended

Mar. 31, 2023

Accounting Policies [Abstract]

Basis of presentation

Basis of presentation — The accompanying unaudited interim financial statements of Wesbanco, Inc. and its consolidated subsidiaries (“Wesbanco”) 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, 2022.

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 2022 Annual Report on Form 10-K filed with the Securities and Exchange Commission, 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. Certain prior period amounts have been reclassified to conform to the current period presentation. Such reclassifications had no impact on Wesbanco’s net income and shareholders’ equity. Results of operations for interim periods are not necessarily indicative of the results of operations that may be expected for a full year.

Modifications for Borrowers Experiencing Financial Difficulty ("MBEFD")

Modifications for Borrowers Experiencing Financial Difficulty (“MBEFD”) — A modification of a loan for borrowers experiencing financial difficulty is applicable when the loan modification results in a direct change in the timing or amount of contractual cash flows. The most common modifications provided to borrowers experiencing financial difficulty are expected to occur in the form of principal forgiveness, interest rate reductions, other-than-insignificant-payment delays, or term extensions under ASC 310-10-50-39. Upon Wesbanco's adoption of Accounting Standards Update (“ASU”) 2022-02 on January 1, 2023, Troubled Debt Restructuring ("TDR") accounting was prospectively discontinued and economic concessions for modifications occurring on or after the adoption date are no longer measured. This accounting also results in the elimination of any existing economic concession related to a loan that was previously designated as a TDR if such loan is restructured on or after January 1, 2023. Due to the elimination of economic concessions under ASU 2022-02, the standard may result in modified loans being subject to the new disclosures that would have not been considered concessions and not treated as TDRs.

When determining whether a debtor is experiencing financial difficulties, consideration is given to any known default on any of its debt or whether it is probable that the debtor would be in payment default in the foreseeable future without the modification. Other indicators of financial difficulty include whether the debtor has declared or is in the process of declaring bankruptcy, the debtor’s ability to continue as a going concern, or the debtor’s projected cash flow to service its debt (including principal & interest) in accordance with the contractual terms for the foreseeable future, without a modification. If the payment of principal at original maturity is primarily dependent on the value of collateral, the current value of that collateral is considered in determining whether the principal will be paid.

The modification of a loan does not increase the allowance or provision for credit losses unless the loan is extended, or the loans are commercial loans that are individually evaluated for impairment, in which case a specific reserve is established pursuant to GAAP. Portfolio segment loss history is the primary factor for establishing the allowance for residential real estate, home equity and consumer MBEFDs.

Non-accrual loans that are restructured remain on non-accrual, but may move to accrual status after they have performed according to the restructured terms for a period of time. MBEFDs on accrual status generally remain on accrual as long as they continue to perform in accordance with their modified terms. MBEFDs may also be placed on non-accrual if they do not perform in accordance with the restructured terms. Loans may be removed from MBEFD status after they have performed according to the renegotiated terms for a period of time.

Recent accounting pronouncements

Recent accounting pronouncements—The Financial Accounting Standards Board (“FASB”) issued Accounting Standards Updates (“ASU”) as noted below.

ASU 2023-02 – Investments Equity Method and Joint Ventures (Topic 323)

In March 2023, the FASB issued ASU 2023-02, Investments—Equity Method and Joint Ventures (Topic 323): Accounting for Investments in Tax Credit Structures Using the Proportional Amortization Method. ASU 2023-02 allows reporting entities to elect to account for qualifying tax equity investments using the proportional amortization method, regardless of the program giving rise to the related income tax credits. The ASU’s amendments “remove the specialized guidance for [low-income-housing tax credit] investments that are not accounted for using the proportional amortization method and instead require that those LIHTC investments be accounted for using the guidance in other [GAAP].” For Wesbanco, the amendments are effective for fiscal years beginning after December 15, 2023, including interim periods within those fiscal years. The adoption of this pronouncement is not expected to have a material impact on the Consolidated Financial Statements.

ASU 2023-01 - Leases (Topic 842): Common Control Arrangements

In March 2023, the FASB issued ASU 2023-01, Leases (Topic 842): Common Control Arrangements. ASU 2023-01 amends certain provisions of ASC 842 that apply to arrangements between related parties under common control. Additionally, ASU 2023-01 amends the accounting for leasehold improvements in common-control arrangements for all entities. For Wesbanco, the amendments are effective for fiscal years beginning after December 15, 2023, including interim periods within those fiscal years. Early adoption is permitted in any annual or interim period as of the beginning of the related fiscal year. The adoption of this pronouncement is not expected to have a material impact on the Consolidated Financial Statements.

ASU 2022-04 Liabilities – Supplier Finance Programs (Sub-topic 405-50)

In September 2022, the FASB issued ASU 2022-04, “Liabilities—Supplier Finance Programs (Subtopic 405-50).” The amendments in this ASU require that a buyer in a supplier finance program disclose sufficient information about the program to allow a user of financial statements to understand the program’s nature, activity during the period, changes from period to period, and potential magnitude. To achieve that objective, the buyer should disclose qualitative and quantitative information about its supplier finance programs. For Wesbanco, this update was effective beginning on January 1, 2023, except for the amendment on rollforward information, which is effective for fiscal years beginning after December 15, 2023. The adoption of this full pronouncement is not expected to have a material impact on the Consolidated Financial Statements.

ASU 2022-03 Fair Value Measurement (Topic 820)

In June 2022, the FASB issued ASU 2022-03, "Fair Value Measurement (Topic 820).” The amendments in this ASU clarify that a contractual restriction on the sale of an equity security is not considered part of the unit of account of the equity security, and therefore, is not considered in measuring fair value. Furthermore, the amendments to this ASU clarify that an entity cannot, as a separate unit of account, recognize and measure a contractual sale restriction. The update to this ASU requires the following disclosures for equity securities: (1) The fair value of equity securities subject to contractual sale restrictions reflected in the balance sheet; (2) The nature and remaining duration of the restriction(s) and; (3) The circumstances that could cause a lapse in the restriction(s). The amendments in this Update are effective for fiscal years beginning after December 15, 2023, and interim periods within those fiscal years. Wesbanco is currently assessing the impact of ASU 2022-03 on its Consolidated Financial Statements.

ASU 2022-02 Financial Instruments - Credit Losses (Topic 326)

In March 2022, the FASB issued ASU 2022-02, "Financial Instruments - Credit Losses (Topic 326)." The amendments in this ASU eliminate the accounting guidance for TDRs by creditors in Subtopic 310-40, "Receivables - Troubled Debt Restructurings by Creditors," while enhancing disclosure requirements for certain loan refinancings and restructurings by creditors when a borrower is experiencing financial difficulty. Specifically, rather than applying the recognition and measurement guidance for TDRs, an entity must apply the loan refinancing and restructuring guidance in paragraphs 310-20-35-9 through 35-11 to determine whether a modification results in a new loan or a continuation of an existing loan. In addition, for public business entities, the amendments in this Update require that an entity disclose current-period gross writeoffs by year of origination for financing receivables and net investments in leases within the scope of Subtopic 326-20, "Financial Instruments - Credit Losses - Measured at Amortized Cost." For Wesbanco, this update was effective beginning on January 1, 2023. The adoption of this pronouncement did not have a material impact on the Consolidated Financial Statements. For the additional disclosure requirements in this ASU, please refer to Footnote 4, "Loans and the Allowance for Credit Losses."

ASU 2020-04, ASU 2021-01 and ASU 2022-06 Reference Rate Reform (Topic 848)

In March 2020, the FASB issued ASU 2020-04, “Reference Rate Reform (Topic 848).” This ASU provided temporary, optional guidance to ease the potential burden in accounting for, or recognizing the effects of, the transition away from the London Interbank Offered Rate ("LIBOR") or other reference rate expected to be discontinued on financial reporting. The ASU also provides optional expedients for contract modifications that replace a reference rate affected by reference rate reform. The guidance is effective as of March 12, 2020 through December 31, 2022, and can be adopted at any time during this period. In January 2021, the FASB issued ASU 2021-01, “Reference Rate Reform (Topic 848): Scope.” This ASU refines the scope of Topic 848 and addresses questions about whether Topic 848 can be applied to derivative instruments that do not reference a rate that is expected to be discontinued, but that use an interest rate for margining, discounting or contract price alignment that is expected to be modified as a result of reference rate reform. ASU 2021-01 is effective upon issuance through December 31, 2024, and can be adopted at any time during this period. Wesbanco has not offered LIBOR for any new contracts after December 31, 2021. Wesbanco has chosen the One Month Term Secured Overnight Financing Rate ("1M Term SOFR") as its alternative replacement rate for LIBOR on both back-to-back swaps and on one-month variable loans. A transition plan was implemented in 2021 to identify and modify Wesbanco's loans and other financial instruments with attributes that are either directly or indirectly influenced by LIBOR, and Wesbanco continues to assess the impact of adopting the new guidance on the consolidated financial statements on an ongoing basis, with no material impacts expected at this time. In December 2022, the FASB issued ASU 2022-06, “Reference Rate Reform (Topic 848): Deferral of the Sunset Date of Topic 848.” In the Update, the Board decided to defer the sunset date of Topic 848 to December 31, 2024, to permit entities to apply the guidance in Topic 848 through the expected cessation date of USD LIBOR. In the Board’s view, that time frame would have been sufficient to provide flexibility for additional unforeseen changes to the timeline of USD LIBOR cessation and to accommodate global interbank offered rate (IBOR) transition. The update is not expected to have a material impact on Wesbanco’s Consolidated Financial Statements.
