1.Purpose. This Policy sets forth the terms on which the Company may recover erroneously awarded compensation to its executive officers. This Policy is intended to comply with Section 10D of the Exchange Act and Section 303A.14 of the NYSE Listed Company Manual.

(g)“executive officer” means the Company’s president, principal financial officer, principal accounting officer (or if there is no such accounting officer, the controller), any vice-president of the Company in charge of a principal business unit, division or function (such as sales, administration or finance), any other officer who performs a policy-making function, or any other person who performs similar policy-making functions for the Company. Executive officers of the Company’s parent(s) or subsidiaries are deemed executive officers of the Company if they perform such policy-making functions for the Company. Policy-making function is not intended to include policy-making functions that are not significant. An “executive officer” for purposes of this Policy includes the executive officers identified pursuant to Item 401(b) of SEC Regulation S-K.

(h)“financial reporting measures” means measures that are determined and presented in accordance with the accounting principles used in preparing the Company’s financial statements, and any measures that are derived wholly or in part from such measures. Stock price and total shareholder return are also financial reporting measures.

(k)“received” has the following meaning: incentive-based compensation is deemed received in the Company’s fiscal period during which the financial reporting measure specified in the incentive-based compensation award is attained, even if the payment or grant of the incentive-based compensation occurs after the end of that period.

3.Recovery of Erroneously Awarded Compensation. The Company shall recover reasonably promptly the amount of erroneously awarded incentive-based compensation in the event that the Company is required to prepare an accounting restatement due to the material noncompliance of the Company with any financial reporting requirement under the securities laws, including any required accounting restatement to correct an error in previously issued financial statements that is material to the previously issued financial statements, or that would result in a material misstatement if the error were corrected in the current period or left uncorrected in the current period.

(iv)During the three completed fiscal years immediately preceding the date that the Company is required to prepare an accounting restatement as described in the first paragraph of this Section 3. The Company’s obligation to recover erroneously awarded compensation is not dependent on if or when the restated financial statements are filed.

(b)Date of Accounting Restatement. The date that the Company is required to prepare an accounting restatement as described in the first paragraph of this Section 3 is the earlier to occur of:

(i)the date on which the Board, a committee thereof or the Company’s officer(s) authorized to take such action if Board action is not required, concludes, or reasonably should have concluded, that the Company is required to prepare an accounting restatement as described in the first paragraph of this Section 3; and

(c)Amount Subject to Recovery. The amount of incentive-based compensation subject to this Policy (“erroneously awarded compensation”) is the amount of incentive-based compensation received that exceeds the amount of incentive-based compensation that otherwise would have been received had it been determined based on the restated amounts and shall be computed without regard to any taxes paid. For incentive-based compensation based on stock price or total shareholder return, where the amount of erroneously awarded compensation is not subject to mathematical recalculation directly from the information in an accounting restatement: (i) the amount shall be based on a reasonable estimate of the effect of the accounting restatement on the stock price or total shareholder return upon which the incentive-based compensation was received; and (ii) the

(d)Impracticability of Recovery. The Company shall recover erroneously awarded compensation in compliance with this Policy except to the extent that the conditions of clauses (i), (ii) or (iii) below are met, and the Committee (or in the absence thereof, a majority of the independent directors serving on the Board) has made a determination that recovery would be impracticable.

(i)The direct expense paid to a third party to assist in enforcing this Policy would exceed the amount to be recovered. Before concluding that it would be impracticable to recover any amount of erroneously awarded compensation based on expense of enforcement, the Company shall make a reasonable attempt to recover such erroneously awarded compensation, document such reasonable attempt(s) to recover, and provide that documentation to the Exchange.

(ii)Recovery would violate home country law where that law was adopted prior to November 28, 2022. Before concluding that it would be impracticable to recover any amount of erroneously awarded compensation based on violation of home country law, the Company shall obtain an opinion of home country counsel, acceptable to the Exchange, that recovery would result in such a violation, and shall provide such opinion to the Exchange.

(iii)Recovery would likely cause an otherwise tax-qualified retirement plan, under which benefits are broadly available to employees of the Company, to fail to meet the requirements of 26 U.S.C. 401(a)(13) or 26 U.S.C. 411(a) and regulations thereunder.

(f)Method of Recovery. The Committee shall determine, in its sole and exclusive discretion, the method or methods for recovering any erroneously awarded compensation, which methods need not be the same, or applied in the same manner, to each executive officer, provided that any such method shall provide for reasonably prompt recovery and otherwise comply with any requirements of the Exchange.

4.Disclosure. The Company shall file all disclosures with respect to this Policy in accordance with the requirements of the Federal securities laws, including the disclosure required by the applicable rules of the SEC.

(a)Effective Date. This Policy shall take effect on October 2, 2023 and shall supplement the WESCO International, Inc. Clawback Policy, dated April 11, 2013 (the “Existing Policy”).

(b)Authority of Committee. This Policy shall be administered and interpreted by the Committee in accordance with Section 303A.14 of the NYSE Listed Company Manual, Section 10D of the Exchange Act and other applicable Federal securities laws and regulations. Except as limited by applicable law, and subject to the

provisions of this Policy, the Committee shall have full power, authority and sole and exclusive discretion to construe, interpret and administer this Policy, and to delegate its authority pursuant to this Policy. In addition, the Committee shall have full and exclusive power to adopt such rules, regulations and guidelines for carrying out this Policy and to amend this Policy, in each case, as it may deem necessary or proper. Subject to Section 3(d), this Policy also may be administered by the Board, and references in this Policy to the “Committee” shall be understood to refer to the full Board. Before the Committee determines to seek recovery pursuant to this Policy, it shall provide, where feasible, the executive officer or former executive officer with written notice and the opportunity to be heard, at a meeting of the Committee (which may be in-person or telephonic, as determined by the Committee).

(c)Decisions Binding. In making any determination or in taking or not taking any action under this Policy, the Committee may obtain and rely on the advice of experts, including employees of, and professional advisors to, the Company. Any action taken by, or inaction of, the Committee or its delegates relating to or pursuant to this Policy that are taken or made in good faith shall be within the absolute discretion of the Committee or its delegates. Such action or inaction of the Committee or its delegates shall be conclusive and binding on the Company and any current or former executive officer affected by such action or inaction.

(d)Policy Not Exclusive. Any right of recovery under this Policy is in addition to, and not in lieu of, any other remedies or rights of recovery, recoupment, forfeiture or offset that may be available to the Company pursuant to the terms of any other applicable Company policy (including the Existing Policy), compensation or benefit plan, agreement or arrangement or other agreement or applicable law; provided, however, that there shall be no duplication of recovery under this Policy, the Existing Policy or any other remedies or rights.
