EXPLANATORY NOTE

This is (i) Post-Effective Amendment No. 1 to the Registration Statement on Form S-8 (File No. 333-107736) (the “2003 Form S-8”), filed by Wesbanco, Inc. (the “Registrant”) with the Securities and Exchange Commission (the “Commission”) on August 7, 2003, relating to the Wesbanco, Inc. Incentive Bonus, Option and Restricted Stock Plan (the “Prior Plan”); (ii) Post-Effective Amendment No. 1 to the Registration Statement on Form S-8 (File No. 333-166541) (the “2010 Form S-8”), filed by the Registrant with the Commission on May 5, 2010, relating to the Prior Plan; (iii) Post-Effective Amendment No. 1 to the Registration Statement on Form S-8 (File No. 333-217398) (the “2017 Form S-8”), filed by the Registrant with the Commission on April 20, 2017, relating to the Prior Plan; (iv) Post-Effective Amendment No. 1 to the Registration Statement on Form S-8 (File No. 333-255443) (the “2021 Form S-8”), filed by the Registrant with the Commission on April 22, 2021, relating to the Prior Plan; and (v) Post-Effective Amendment No. 1 to the Registration Statement on Form S-8 (File No. 333-278833) (the “2024 Form S-8”), filed by the Registrant with the Commission on April 19, 2024, relating to the Prior Plan.

On April 15, 2026 (the “Effective Date”), the Registrant’s shareholders approved the Wesbanco, Inc. 2026 Equity Incentive Plan (the “2026 Plan”). Under the terms of the 2026 Plan, no further awards may be made under the Prior Plan as of the Effective Date. Contemporaneously with the filing of this Post-Effective Amendment, the Registrant is filing a Registration Statement on Form S-8 with the Commission to register the offer and sale of 1,665,046 newly authorized shares under the 2026 Plan.

As of the Effective Date, (i) an aggregate of 3,006,400 shares of Common Stock were issued by the Registrant pursuant to vested awards granted under the Prior Plan, (ii) 1,579,898 shares of Common Stock were subject to outstanding awards under the Prior Plan, and (iii) 1,313,702 shares of Common Stock were available for the granting of awards under the Prior Plan. An aggregate of 1,772,378 shares, consisting of (i) 1,579,898 shares of Common Stock which were subject to outstanding awards under the Prior Plan as of the Effective Date and (ii) 192,480 shares of Common Stock which will remain in the Prior Plan to satisfy dividend equivalent rights on awards outstanding under the Prior Plan on such date and related to dividends and distributions to be paid after such date, would become available for issuance under the 2026 Plan if such related awards subsequent to the Effective Date are terminated or cancelled without having been exercised or are forfeited, cancelled or repurchased by the Registrant (to the extent of such termination, cancellation, forfeiture or repurchase).

The 2003 Form S-8, the 2010 Form S-8 and the 2017 Form S-8 registered the offer and sale of an aggregate of 2,800,000 shares of Common Stock. All shares of Common Stock covered by each of the 2003 Form S-8, the 2010 Form S-8 and the 2017 Form S-8 were offered and sold pursuant thereto. The Registrant is filing Post-Effective Amendment No. 1 to the 2003 Form S-8, Post-Effective Amendment No. 1 to the 2010 Form S-8 and Post Effective Amendment No. 1 to the 2017 Form S-8 to reflect that the offering and sale of shares of Common Stock under each such registration statement has been terminated.

The 2021 Form S-8 registered the offer and sale of 2,000,000 shares of Common Stock. As of the Effective Date, (i) 206,400 shares of Common Stock covered by the 2021 Form S-8 were offered and sold pursuant thereto by means of vested awards granted under the Prior Plan; (ii) 1,579,898 shares of Common Stock covered by the 2021 Form S-8 were subject to outstanding awards under the Prior Plan; and (iii) 213,702 shares of Common Stock covered by the 2021 Form S-8 remained available for offer and sale pursuant thereto. In addition to the 1,579,898 shares of Common Stock covered by the 2021 Form S-8 that were subject to outstanding awards under the Prior Plan as of the Effective Date, 192,480 shares of Common Stock covered by the 2021 Form S-8 will remain in the Prior Plan to satisfy dividend equivalent rights on outstanding awards under the Prior Plan on such date and related to dividends and distributions to be paid after such date. Pursuant to the undertaking in Item 512(a)(1)(iii) of Regulation S-K that the Registrant disclose a material change in the plan of distribution, and pursuant to the Commission’s Corporation Finance Interpretation Question 126.43, the Registrant is filing this Post-Effective Amendment No. 1 to the 2021 Form S-8 to reflect that (a) 213,702 shares of Common Stock that remained available for offer and sale pursuant to the 2021 Form S-8 as of the Effective Date instead may be offered and sold under the 2026 Plan, and (b) up to 1,772,378 shares of Common Stock, consisting of (1) up to 1,579,898 shares of Common Stock that are currently subject to outstanding awards under the Prior Plan and (2) up to 192,480 shares of Common Stock being retained for availability under the Prior Plan to satisfy dividend equivalent rights on awards outstanding under the Prior Plan on the Effective Date and related to dividends and distributions to be paid after the Effective Date, instead be offered and sold under the 2026 Plan if such awards subsequent to the Effective Date are terminated or cancelled without having been exercised or are forfeited, cancelled or repurchased by the Registrant (to the extent of such termination, cancellation, forfeiture or repurchase).

The 2024 Form S-8 registered the offer and sale of 1,100,000 shares of Common Stock. As of the Effective Date, (i) no shares of Common Stock covered by the 2024 Form S-8 were offered and sold pursuant thereto; (ii) no shares of Common Stock covered by the 2021 Form S-8 were subject to outstanding awards under the Prior Plan; and (iii) 1,100,000 shares of Common Stock covered by the 2024 Form S-8 remained available for offer and sale pursuant thereto. Pursuant to the undertaking in Item 512(a)(1)(iii) of Regulation S-K that the Registrant disclose a material change in the plan of distribution, and pursuant to the Commission’s Corporation Finance Interpretation Question 126.43, the Registrant is filing this Post-Effective Amendment No. 1 to the 2021 Form S-8s to reflect that 1,100,000 shares of Common Stock that remained available for offer and sale pursuant to the 2021 Form S-8 as of the Effective Date instead may be issued under the 2026 Plan.

ITEM 6. INDEMNIFICATION OF DIRECTORS AND OFFICERS.

The Registrant’s Bylaws provide, and West Virginia law permits, the indemnification of directors and officers against certain liabilities. Officers and directors of the Registrant and its subsidiaries are indemnified, to the maximum extent permitted under the West Virginia Business Corporation Act (including advanced indemnification payments), against liabilities incurred in connection with proceedings in which they are made parties by reason of their being or having been directors or officers of the corporation, except for certain prohibitions set forth in the Registrant’s Bylaws regarding “prohibited indemnification payments.” The Registrant does provide indemnity insurance to its officers and directors. Such insurance will not, however, indemnify officers or directors for willful misconduct or gross negligence in the performance of a duty to the Registrant.

I. Article VI of the Bylaws of Wesbanco provides:

Indemnification of Directors and Officers

SECTION 1. Indemnification . Each director and officer, whether or not then in office, shall be indemnified by the corporation against liability incurred by and imposed upon him in connection with or resulting from any action, suit or proceeding, to which he may be made a party by reason of his being or having been a director or officer of the corporation, or of any other company which he served at the request of the corporation, to the maximum extent permitted under the West Virginia Business Corporation Act, except as prohibited by Section 2 and Section 4 of this Article VI. The foregoing right of indemnification shall not be exclusive of other rights to which he may be entitled as a matter of law. Expenses incurred in defending a civil or criminal action, suit or proceeding may be paid by the corporation in advance of the final disposition of such action, suit or proceeding as authorized by the board of directors in accordance with the provisions of the West Virginia Business Corporation Act.

SECTION 2. Prohibited Indemnification Payment. Notwithstanding the provisions of Section 1 of this Article VI, no director or officer shall receive a “prohibited indemnification payment,” which is any payment or agreement to make a payment to pay or reimburse such director or officer for any liability or legal expenses in any administrative proceeding brought by the appropriate federal banking agency that results in a final order or settlement in which the director or officer is assessed a civil money penalty, is removed or prohibited from conducting the business of banking, or is required to cease an action or take any affirmative action, including making restitution, with respect to Wesbanco Bank, Inc. or the corporation.

SECTION 3. Insurance. The corporation may purchase commercial insurance to cover certain costs that the corporation incurs under the indemnification provisions of Section 1 of this Article VI. Costs that may be covered include legal expenses and restitution that an individual may be ordered to make to the corporation. Such insurance may not, however, pay or reimburse a director or officer for any final judgment or civil money penalty assessed against such individual. Furthermore, partial indemnification for legal expenses is permitted in connection with a settlement when there is a formal and final finding that the director or officer has not breached a fiduciary duty, engaged in unsafe or unsound practices, and is not subject to a final prohibition order.

SECTION 4. Determination that Indemnification is Proper. The corporation may make or agree to make a reasonable indemnification payment if all of the following conditions are met: (i) the board of directors investigates and determines in writing that the director or officer acted in good faith and in the best interests of Wesbanco Bank, Inc.; (ii) the board of directors investigates and determines that the payment will not materially adversely affect the safety and soundness of Wesbanco Bank, Inc. or the corporation; (iii) the payment does not fall within the definition of a prohibited indemnification payment; and (iv) the director or officer agrees in writing to reimburse the corporation, to the extent not covered by permissible insurance, for advanced indemnification payments that subsequently become prohibited indemnification payments.

II. W. Va. Code Section 31D-8-851 through Section 31D-8-856 provides:

Section 31D-8-851. Permissible Indemnification.

(a) Except as otherwise provided in this section, a corporation may indemnify an individual who is a party to a proceeding because he or she is a director against liability incurred in the proceeding if:

(1) (A) He or she conducted himself or herself in good faith; and

(B) He or she reasonably believed: (i) In the case of conduct in his or her official capacity, that his or her conduct was in the best interests of the corporation; and (ii) in all other cases, that his or her conduct was at least not opposed to the best interests of the corporation; and

(C) In the case of any criminal proceeding, he or she had no reasonable cause to believe his or her conduct was unlawful; or

(2) He or she engaged in conduct for which broader indemnification has been made permissible or obligatory under a provision of the articles of incorporation as authorized by subdivision (5), subsection (b), section two hundred two, article two of this chapter.

(b) A director’s conduct with respect to an employee benefit plan for a purpose he or she reasonably believed to be in the interests of the participants in, and the beneficiaries of, the plan is conduct that satisfies the requirement of subparagraph (ii), paragraph (B), subdivision (1), subsection (a) of this section.

(c) The termination of a proceeding by judgment, order, settlement or conviction, or upon a plea of nolo contendere or its equivalent, is not determinative that the director did not meet the relevant standard of conduct described in this section.

(d) Unless ordered by a court under subdivision (3), subsection (a), section eight hundred fifty-four of this article, a corporation may not indemnify a director:

(1) In connection with a proceeding by or in the right of the corporation, except for reasonable expenses incurred in connection with the proceeding if it is determined that the director has met the relevant standard of conduct under subsection (a) of this section; or

(2) In connection with any proceeding with respect to conduct for which he or she was adjudged liable on the basis that he or she received a financial benefit to which he or she was not entitled, whether or not involving action in his or her official capacity.

Section 31D-8-852. Mandatory Indemnification.

A corporation must indemnify a director who was wholly successful, on the merits or otherwise, in the defense of any proceeding to which he or she was a party because he or she was a director of the corporation against reasonable expenses incurred by him or her in connection with the proceeding.

Section 31D-8-853. Advance for Expenses.

(a) A corporation may, before final disposition of a proceeding, advance funds to pay for or reimburse the reasonable expenses incurred by a director who is a party to a proceeding because he or she is a director if he or she delivers to the corporation:

(1) A written affirmation of his or her good faith belief that he or she has met the relevant standard of conduct described in section eight hundred fifty-one of this article or that the proceeding involves conduct for which liability has been eliminated under a provision of the articles of incorporation as authorized by subdivision (4), subsection (b), section two hundred two, article two of this chapter; and

(2) His or her written undertaking to repay any funds advanced if he or she is not entitled to mandatory indemnification under section eight hundred fifty-two of this article and it is ultimately determined under section eight hundred fifty-four or eight hundred fifty-five of this article that he or she has not met the relevant standard of conduct described in section eight hundred fifty-one of this article.

(b) The undertaking required by subdivision (2), subsection (a) of this section must be an unlimited general obligation of the director but need not be secured and may be accepted without reference to the financial ability of the director to make repayment.

(1) By the board of directors:

(A) If there are two or more disinterested directors, by a majority vote of all the disinterested directors, a majority of whom constitute a quorum for this purpose, or by a majority of the members of a committee of two or more disinterested directors appointed by a vote; or

(B) If there are fewer than two disinterested directors, by the vote necessary for action by the board in accordance with subsection (c), section eight hundred twenty-four of this article in which authorization directors who do not qualify as disinterested directors may participate; or

(2) By the shareholders, but shares owned by or voted under the control of a director who at the time does not qualify as a disinterested director may not be voted on the authorization; or

(3) By special legal counsel selected in a manner in accordance with subdivision (2), subsection (b), section eight hundred fifty-five of this article.

Section 31D-8-854. Circuit Court-Ordered Indemnification and Advance for Expenses.

(a) A director who is a party to a proceeding because he or she is a director may apply for indemnification or an advance for expenses to the circuit court conducting the proceeding or to another circuit court of competent jurisdiction. After receipt of an application and after giving any notice it considers necessary, the circuit court shall:

(1) Order indemnification if the circuit court determines that the director is entitled to mandatory indemnification under section eight hundred fifty-two of this article;

(2) Order indemnification or advance for expenses if the circuit court determines that the director is entitled to indemnification or advance for expenses pursuant to a provision authorized by subsection (a), section eight hundred fifty-eight of this article; or

(3) Order indemnification or advance for expenses if the circuit court determines, in view of all the relevant circumstances, that it is fair and reasonable:

(A) To indemnify the director; or

(B) To advance expenses to the director, even if he or she has not met the relevant standard of conduct set forth in subsection (a), section eight hundred fifty-one of this article, failed to comply with section eight hundred fifty-three of this article or was adjudged liable in a proceeding referred to in subdivision (1) or (2), subsection (d), section eight hundred fifty-one of this article, but if he or she was adjudged so liable his or her indemnification is to be limited to reasonable expenses incurred in connection with the proceeding.

(b) If the circuit court determines that the director is entitled to indemnification under subdivision (1), subsection (a) of this section or to indemnification or advance for expenses under subdivision (2) of said subsection, it shall also order the corporation to pay the director’s reasonable expenses incurred in connection with obtaining circuit court-ordered indemnification or advance for expenses. If the circuit court determines that the director is entitled to indemnification or advance for expenses under subdivision (3) of said subsection, it may also order the corporation to pay the director’s reasonable expenses to obtain circuit court-ordered indemnification or advance for expenses.

Section 31D-8-855. Determination and Authorization of Indemnification.

(a) A corporation may not indemnify a director under section eight hundred fifty-one of this article unless authorized for a specific proceeding after a determination has been made that indemnification of the director is permissible because he or she has met the relevant standard of conduct set forth in section eight hundred fifty-one of this article.

(b) The determination is to be made:

(1) If there are two or more disinterested directors, by the board of directors by a majority vote of all the disinterested directors, a majority of whom constitute a quorum for this purpose, or by a majority of the members of a committee of two or more disinterested directors appointed by a vote;

(2) By special legal counsel:

(A) Selected in the manner prescribed in subdivision (1) of this subsection; or

(B) If there are fewer than two disinterested directors, selected by the board of directors in which selection directors who do not qualify as disinterested directors may participate; or

(3) By the shareholders, but shares owned by or voted under the control of a director who at the time does not qualify as a disinterested director may not be voted on the determination.

(c) Authorization of indemnification is to be made in the same manner as the determination that indemnification is permissible, except that if there are fewer than two disinterested directors or if the determination is made by special legal counsel, authorization of indemnification is to be made by those entitled under paragraph (B), subdivision (2), subsection (b) of this section to select special legal counsel.

Section 31D-8-856. Indemnification of Officers.

(a) A corporation may indemnify and advance expenses under this part to an officer of the corporation who is a party to a proceeding because he or she is an officer of the corporation:

(1) To the same extent as a director; and

(2) If he or she is an officer but not a director, to a further extent as may be provided by the articles of incorporation, the bylaws, a resolution of the board of directors or contract except for:

(A) Liability in connection with a proceeding by or in the right of the corporation other than for reasonable expenses incurred in connection with the proceeding; or

(B) Liability arising out of conduct that constitutes:

(i) Receipt by him or her of a financial benefit to which he or she is not entitled;

(ii) An intentional infliction of harm on the corporation or the shareholders; or

(iii) An intentional violation of criminal law.

(b) The provisions of subdivision (2), subsection (a) of this section apply to an officer who is also a director if the basis on which he or she is made a party to the proceeding is an act or omission solely as an officer.

(c) An officer of a corporation who is not a director is entitled to mandatory indemnification under section eight hundred fifty-two of this article and may apply to a court under section eight hundred fifty-four of this article for indemnification or an advance for expenses in each case to the same extent to which a director may be entitled to indemnification or advance for expenses under those provisions.

Certain rules of the Federal Deposit Insurance Corporation limit the ability of certain depository institutions, their subsidiaries and their affiliated depository institution holding companies to indemnify affiliated parties, including institution directors. In general, subject to the ability to purchase directors’ and officers’ liability insurance and to advance professional expenses under certain circumstances, the rules prohibit such institutions from indemnifying a director for certain costs incurred with regard to an administrative or enforcement action commenced by any federal banking agency that results in a final order or settlement pursuant to which the director is assessed a civil money penalty, removed from office, prohibited from participating in the affairs of an insured depository institution or required to cease and desist from or take an affirmative action described in Section 8(b) of the Federal Deposit Insurance Act (12 U.S.C. § 1818(b)).

Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than 20% change in the maximum aggregate offering price set forth in the “Calculation of Filing Fee Tables” or “Calculation of Registration Fee” table, as applicable, in the effective Registration Statement.

iii. To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in this Registration Statement;

provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) of this section do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the Commission by the Registrant pursuant to Section 13 or Section 15(d) of the Exchange Act that are incorporated by reference in this Registration Statement.

2. That, for the purpose of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

3. To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

(b) The undersigned Registrant hereby undertakes that, for purposes of determining any liability under the Securities Act, each filing of the Registrant’s annual report pursuant to Section 13(a) or Section 15(d) of the Exchange Act (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to Section 15(d) of the Exchange Act) that is incorporated by reference in this Registration Statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(c) Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the Registrant pursuant to the foregoing provisions, or otherwise, the Registrant has been advised that in the opinion of the Commission such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Registrant of expenses incurred or paid by a director, officer or controlling person of the Registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.
