1. ORGANIZATION
WESCO International, Inc. (“Wesco International”) and its subsidiaries (collectively, “Wesco” or the “Company”), headquartered in Pittsburgh, Pennsylvania, is a leading provider of business-to-business distribution, logistics services and supply chain solutions.
The Company has operating segments comprising three strategic business units consisting of Electrical & Electronic Solutions (“EES”), Communications & Security Solutions (“CSS”) and Utility & Broadband Solutions (“UBS”).
2. ACCOUNTING POLICIES
Basis of Presentation
The accompanying unaudited Condensed Consolidated Financial Statements of Wesco have been prepared in accordance with Rule 10-01 of Regulation S-X of the Securities and Exchange Commission (the “SEC”). The unaudited condensed consolidated financial information should be read in conjunction with the audited Consolidated Financial Statements and Notes thereto included in WESCO International, Inc.’s Annual Report on Form 10-K for the year ended December 31, 2024, as filed with the SEC on February 14, 2025. The Condensed Consolidated Balance Sheet at December 31, 2024 was derived from the audited Consolidated Financial Statements as of that date, but does not include all the disclosures required by accounting principles generally accepted in the United States of America.
The unaudited Condensed Consolidated Balance Sheet as of June 30, 2025, the unaudited Condensed Consolidated Statements of Income and Comprehensive Income, the unaudited Condensed Consolidated Statements of Stockholders’ Equity for the three and six months ended June 30, 2025 and 2024, and the unaudited Condensed Consolidated Statements of Cash Flows for the six months ended June 30, 2025 and 2024, respectively, in the opinion of management, have been prepared on the same basis as the audited Consolidated Financial Statements and include all adjustments necessary for the fair statement of the results of the interim periods presented herein. All adjustments reflected in the unaudited condensed consolidated financial information are of a normal recurring nature unless indicated. The results for the interim periods presented herein are not necessarily indicative of the results to be expected for the full year.
Reclassifications
The unaudited Condensed Consolidated Statement of Cash Flows for the six months ended June 30, 2024, includes certain reclassifications to previously reported amounts to conform to the current period's presentation. Such reclassifications had no impact on the totals of operating, investing and financing cash flow activities.
In the first quarter of 2025, a portion of the EES reportable segment was moved to the CSS reportable segment as a result of operational realignment. The reportable segment financial information for the three and six months ended June 30, 2024 has been recast to conform to the current year presentation. The recast does not impact previously reported condensed consolidated results. Refer to Note 14, “Business Segments” for the recasted segment disclosures.
Recently Adopted and Recently Issued Accounting Standards and Disclosure Rules
In November 2023, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standards Update (“ASU”) 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures, which enhances prior reportable segment disclosure requirements in part by requiring entities to disclose significant expenses related to their reportable segments. The amendments in this ASU were effective on a retrospective basis for annual periods beginning after December 15, 2023 and interim periods within fiscal years beginning after December 15, 2024. The Company adopted the annual disclosure requirements of this ASU in the fourth quarter of 2024 and the interim disclosure requirements in the first quarter of 2025. The adoption of this ASU resulted in additional required disclosures, including the disclosure of certain expenses at the reportable segment level, described further in Note 14, “Business Segments”.
In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which requires disaggregated information about a reporting entity's effective tax rate reconciliation as well as information on income taxes paid to enhance the transparency and decision usefulness of income tax disclosures. The amendments in this ASU are effective for annual periods beginning after December 15, 2024 on a prospective basis; however, retrospective application is permitted. Management is currently evaluating the impact that this accounting standard will have on its consolidated financial statements and notes thereto.

In November 2024, the FASB issued ASU 2024-03, Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses, which is intended to enhance expense disclosures, primarily by requiring disclosure of disaggregated information about certain income statement expense line items on an annual and interim basis. The amendments in this ASU are effective for fiscal years beginning after December 15, 2026 and interim periods within fiscal years beginning after December 15, 2027. The amendments in this ASU may be applied prospectively or retrospectively. Management is currently evaluating the impact that this accounting standard will have on its consolidated financial statements and notes thereto.
Other pronouncements issued by the FASB or other authoritative accounting standards groups with future effective dates are either not applicable or are not expected to be material to Wesco’s financial position, results of operations or cash flows.
3. REVENUE
Wesco distributes products and provides services to customers globally in various end markets within its business segments. The segments operate in the United States, Canada and various other countries.
The following table disaggregates Wesco’s net sales by geography for the periods presented:

| Three Months Ended |  | Six Months Ended
| June 30 |  | June 30
(In millions) | 2025 |  | 2024 |  | 2025 |  | 2024
United States | $ | 4,386.9 |  |  | $ | 4,050.5 |  |  | $ | 8,361.5 |  |  | $ | 8,048.1 |
Canada | 804.0 |  |  | 744.4 |  |  | 1,516.8 |  |  | 1,462.9 |
Other International(1) | 708.7 |  |  | 684.8 |  |  | 1,365.0 |  |  | 1,318.7 |
Total by geography(2) | $ | 5,899.6 |  |  | $ | 5,479.7 |  |  | $ | 11,243.3 |  |  | $ | 10,829.7 |

(1) No individual country's net sales are greater than 10% of total net sales.
(2) Wesco attributes revenues from external customers to individual countries on the basis of point of sale.
Due to the terms of certain contractual arrangements, Wesco bills or receives payment from its customers in advance of satisfying the respective performance obligation. Such advance billings or payments are recorded as deferred revenue and recognized as revenue when the performance obligation has been satisfied and control has transferred to the customer, which is generally upon shipment. Deferred revenue is generally recognized within a year or less from the date of the advance billing or payment receipt. At June 30, 2025 and December 31, 2024, $108.7 million and $141.8 million, respectively, of deferred revenue was recorded as a component of other current liabilities in the Condensed Consolidated Balance Sheets. The Company recognized $13.0 million and $70.4 million of revenue during the three and six months ended June 30, 2025, respectively, that was included in the deferred revenue balance as of December 31, 2024, and recognized $14.3 million and $57.1 million of revenue during the three and six months ended June 30, 2024, respectively, that was included in the deferred revenue balance as of December 31, 2023.
Wesco’s revenues are adjusted for variable consideration, which includes customer volume rebates, returns and discounts. Wesco measures variable consideration by estimating expected outcomes using analysis and inputs based upon historical data, as well as current and forecasted information. Variable consideration is reviewed by management on a monthly basis and revenue is adjusted as necessary. Variable consideration reduced revenue by approximately $109.4 million and $110.0 million, for the three months ended June 30, 2025 and 2024, respectively, and by approximately $222.4 million and $220.8 million for the six months ended June 30, 2025 and 2024, respectively. As of June 30, 2025 and December 31, 2024, the Company's estimated product return obligation was $41.9 million and $41.0 million, respectively.
Billings to customers for shipping and handling are recognized in net sales. Wesco has elected to recognize shipping and handling costs as a fulfillment cost. Shipping and handling costs recorded as a component of selling, general and administrative expenses totaled $83.9 million and $75.7 million for the three months ended June 30, 2025 and 2024, respectively, and $160.4 million and $145.3 million for the six months ended June 30, 2025 and 2024, respectively.

4. ACQUISITIONS AND DIVESTITURES
Industrial Software Solutions
On January 2, 2025, the Company acquired 100% of the equity securities of Industrial Software Solutions I, Inc. and Industrial Software Solutions ULC (collectively, “ISS”), an industrial automation consulting company, software distributor, and AVEVA Select Partner, for total cash consideration of $36.3 million, net of cash acquired. The assets acquired primarily included a distribution agreement intangible asset and a customer relationships intangible asset, with fair values of $10.6 million and $5.0 million, respectively, based on income valuation methods, with the excess of $20.1 million primarily allocated to goodwill in the Company’s EES reportable segment.
Ascent, LLC
On December 5, 2024, through its wholly-owned subsidiary Anixter Inc., the Company acquired 100% of the equity securities of Ascent, LLC (“Ascent”). Headquartered in St. Louis, Missouri, Ascent is a provider of data center facility management services with more than 300 employees in the U.S. and Canada. Ascent’s expertise in engineering and design-build consultation services, in addition to daily site operations and critical facility intelligence software, extends the Company’s suite of capabilities and solutions that serve the entire lifecycle of the data center. The Company funded the purchase price paid at closing with cash on hand as well as borrowings under its revolving credit facility. The total fair value of consideration transferred for the acquisition of Ascent consisted of $179.2 million, net of cash acquired.
The preliminary purchase consideration was allocated to the identified assets acquired and liabilities assumed based on their respective acquisition date fair value, with the excess allocated to goodwill. The Company identified a customer relationship intangible asset and estimated its fair value using an income valuation method. The excess purchase consideration recorded as goodwill is not deductible for income tax purposes, and has been assigned to the Company’s CSS reportable segment. The resulting goodwill is primarily attributable to Ascent’s workforce and expertise in engineering and design-build consultation services.
The estimated fair values of assets acquired and liabilities assumed are based on preliminary calculations and valuations using estimates and assumptions at the time of acquisition. As the Company obtains additional information during the measurement period (not to exceed one year from the acquisition date), estimates and assumptions for the preliminary purchase consideration allocations may change materially. Since the initial measurement of the identified assets acquired and liabilities assumed, the Company has not recorded any material fair value adjustments.
The following table sets forth the preliminary allocation of the purchase consideration to the respective fair values of assets acquired and liabilities assumed for the acquisition of Ascent:

Assets | (In millions)

Thereafter | 646.4 |
Total | $ | 1,023.2 |

6. STOCK-BASED COMPENSATION
Wesco’s stock-based compensation awards consist of stock options, stock-settled stock appreciation rights, restricted stock units and performance-based awards. Compensation cost for all stock-based awards is measured at fair value on the date of grant and compensation cost is recognized, net of estimated forfeitures, over the service period for awards expected to vest. The fair value of stock options and stock-settled stock appreciation rights is determined using the Black-Scholes model. The fair value of restricted stock units is determined by the grant-date closing price of Wesco’s common stock. The fair value of performance-based awards with performance conditions is determined by a Monte Carlo simulation as well as the grant-date closing price of Wesco’s common stock. The forfeiture assumption is based on Wesco’s historical participant behavior that is reviewed on at least an annual basis. For stock options and stock-settled stock appreciation rights that are exercised, and for restricted stock units and performance-based awards that vest, shares are issued out of Wesco's outstanding common stock.
Stock options and stock-settled stock appreciation rights vest ratably over a three-year period and terminate on the tenth anniversary of the grant date unless terminated sooner under certain conditions. Restricted stock units awarded under the WESCO International, Inc. 2021 Omnibus Incentive Plan, which was adopted on May 27, 2021, typically vest ratably over a three-year period on each of the first, second and third anniversaries of the grant date. Vesting of performance-based awards is based on a three-year performance period, and the number of shares earned, if any, depends on the attainment of certain performance levels, as described below. Outstanding awards would vest upon the consummation of a change in control transaction, with performance-based awards vesting at the greater of the target level or actual.
Prior to the 2025 awards, performance-based awards were typically based on two equally-weighted performance measures: the three-year average growth rate of Wesco’s net income attributable to common stockholders and the three-year cumulative return on net assets. The 2025 performance-based awards are based on two equally-weighted performance measures: the growth rate of Wesco’s earnings per share and return on net assets, both of which are measured on an annual basis as well as on a three-year cumulative basis, with each of the three years and the three-year cumulative measurement equally-weighted. The 2025 performance-based awards also include a relative Total Stockholder Return (“TSR”) modifier that impacts the number of shares earned based on the Company's TSR over the performance period in relation to the TSR of the companies comprising the S&P MidCap 400 Index. These awards are accounted for as awards with performance conditions; compensation cost is recognized over the performance period based upon Wesco’s determination of whether it is probable that the performance targets will be achieved. The fair value of the relative TSR modifier as of the March 1, 2025 grant date was measured using a Monte Carlo simulation.

During the three and six months ended June 30, 2025 and 2024, Wesco granted the following stock options, restricted stock units, and performance-based awards at the following weighted-average fair values:

| Three Months Ended |  | Six Months Ended
| June 30, 2025 |  | June 30, 2024 |  | June 30, 2025 |  | June 30, 2024
Stock options granted | 4,745 |  |  | — |  |  | 89,221 |  |  | 85,425 |
Weighted-average fair value | $ | 79.03 |  |  | n/a |  | $ | 76.72 |  |  | $ | 72.05 |
Restricted stock units granted | 7,144 |  |  | 35,992 |  |  | 222,747 |  |  | 238,291 |
Weighted-average fair value | $ | 164.30 |  |  | $ | 184.73 |  |  | $ | 179.33 |  |  | $ | 157.19 |
Performance-based awards granted | 4,562 |  |  | 570 |  |  | 76,864 |  |  | 193,565 |
Weighted-average fair value | $ | 194.03 |  |  | $ | 147.40 |  |  | $ | 191.86 |  |  | $ | 108.83 |

The fair values of stock options, as disclosed in the table above, were estimated using the following weighted-average assumptions in the respective periods:

| Three Months Ended |  | Six Months Ended
| June 30, 2025 |  | June 30, 2024 |  | June 30, 2025 |  | June 30, 2024
Risk free interest rate | 4.0 | % |  | n/a |  | 4.1 | % |  | 4.2 | %
Expected life (in years) | 5 |  | n/a |  | 5 |  | 5
Expected volatility | 47 | % |  | n/a |  | 47 | % |  | 55 | %
Expected dividend yield | 0.98 | % |  | n/a |  | 1.01 | % |  | 1.09 | %

The risk-free interest rate is based on the U.S. Treasury Daily Yield Curve rate as of the grant date. The expected life is based on historical exercise experience, the expected volatility is based on the volatility of the Company’s daily stock price over the expected life preceding the grant date of the award, and the expected dividend yield is based on the calculated yield on the Company’s common stock at date of grant using the current fiscal year projected dividend distribution rate.
The following table sets forth a summary of stock options and related information for the six months ended June 30, 2025:

| Awards |  | Weighted- Average Exercise Price |  | Weighted- Average Remaining Contractual Term (In years) |  | Aggregate Intrinsic Value (In millions)
Outstanding at December 31, 2024 | 234,814 |  |  | $ | 147.08 |  |  |  |  |
Granted | 89,221 |  |  | 180.72 |  |  |  |  |
Exercised | (2,139) |  |  | 140.90 |  |  |  |  |
Forfeited | (12,488) |  |  | 169.83 |  |  |  |  |
Outstanding at June 30, 2025 | 309,408 |  |  | $ | 155.90 |  |  | 8.0 |  | $ | 9.1 |
Exercisable at June 30, 2025 | 153,368 |  |  | $ | 141.94 |  |  | 6.8 |  | $ | 6.6 |

For the six months ended June 30, 2025, the aggregate intrinsic value of stock options exercised during such period was not material.

7. STOCKHOLDERS’ EQUITY
Share Repurchases
On May 31, 2022, the Company’s Board of Directors adopted a resolution authorizing the repurchase of up to $1 billion of the Company’s common stock and 10.625% Series A Fixed-Rate Reset Cumulative Perpetual Preferred Stock (the “Series A Preferred Stock”). The share repurchase authorization has no expiration date and may be modified, suspended, or terminated at any time without prior notice.
During the three and six months ended June 30, 2025, the Company entered into spot repurchase transactions through a broker to purchase 147,300 and 300,528 shares, respectively, of its common stock in the open market for cash totaling $25.3 million and $50.6 million, respectively, including excise taxes. Wesco funded the repurchases with available cash and borrowings under its accounts receivable securitization and revolving credit facilities. During the three and six months ended June 30, 2024, the Company entered into spot repurchase transactions through a broker to purchase 1,679,176 and 2,022,323 shares, respectively, of its common stock in the open market for cash totaling $303.0 million and $353.5 million, respectively, including excise taxes. Wesco funded the repurchases with available cash and borrowings under its accounts receivable securitization and revolving credit facilities.
Series A Preferred Stock Redemption
On February 13, 2025, the Company's Board of Directors adopted a resolution authorizing the redemption of all outstanding shares of the Company's Series A Preferred Stock. As this authorization was separate from the May 31, 2022 share purchase authorization noted above, the redemption of Series A Preferred Stock did not impact the approximate dollar value of shares that may be repurchased under the earlier 2022 authorization.
As of June 22, 2025, the Company redeemed all 21,612 outstanding shares of its Series A Preferred Stock, and the related depositary shares, each representing 1/1,000th of one share of Series A Preferred Stock, at a redemption price of $25,000 per share, for a total payment of $540.3 million. The Company accrued $5.4 million in excise tax and recognized a $27.6 million gain from the redemption as income attributable to common stockholders. As described in Note 9, “Debt”, Wesco funded the redemption with the net proceeds from the March 2025 issuance of the 6.375% senior notes due 2033.
Dividends
The Company’s dividends on common stock are declared at the discretion of the Board of Directors. The following table is a summary of cash dividends declared and paid on the Company’s common stock for the six months ended June 30, 2025:

For the three months ended June 30, 2025, the dividend rate per depositary share was prorated to $0.598, compared to the prior period dividend rates of $0.664, as a result of the redemption of the Series A Preferred Stock in June 2025. During the three and six months ended June 30, 2024, the Company's Board of Directors declared and the Company paid quarterly cash dividends of $0.664 per depositary share relating to its Series A Preferred Stock totaling $14.4 million and $28.7 million, respectively.
8. EARNINGS PER SHARE
Basic earnings per share is computed by dividing net income attributable to common stockholders by the weighted-average number of common shares outstanding during the periods. Diluted earnings per share is computed by dividing net income attributable to common stockholders by the weighted-average common shares and common share equivalents outstanding during the periods. The dilutive effect of common share equivalents is considered in the diluted earnings per share computation using the treasury stock method, which includes consideration of equity awards.
The following table sets forth the computation of basic and diluted earnings per share for the periods presented:

| Three Months Ended |  | Six Months Ended
| June 30 |  | June 30
(In millions, except per share data) | 2025 |  | 2024 |  | 2025 |  | 2024
Net income attributable to WESCO International, Inc. | $ | 174.5 |  |  | $ | 232.1 |  |  | $ | 292.9 |  |  | $ | 347.9 |
Plus: Gain on redemption of Series A Preferred Stock | 27.6 |  |  | — |  |  | 27.6 |  |  | — |
Less: Preferred stock dividends | 12.9 |  |  | 14.4 |  |  | 27.3 |  |  | 28.7 |
Net income attributable to common stockholders | $ | 189.2 |  |  | $ | 217.7 |  |  | $ | 293.2 |  |  | $ | 319.2 |
Weighted-average common shares outstanding used in computing basic earnings per share | 48.8 |  |  | 50.2 |  |  | 48.8 |  |  | 50.5 |
Common shares issuable upon exercise of dilutive equity awards | 0.6 |  |  | 0.7 |  |  | 0.7 |  |  | 0.8 |
Weighted-average common shares outstanding and common share equivalents used in computing diluted earnings per share | 49.4 |  |  | 50.9 |  |  | 49.5 |  |  | 51.3 |
Earnings per share attributable to common stockholders |  |  |  |  |  |  |
Basic | $ | 3.88 |  |  | $ | 4.34 |  |  | $ | 6.01 |  |  | $ | 6.32 |
Diluted | $ | 3.83 |  |  | $ | 4.28 |  |  | $ | 5.92 |  |  | $ | 6.22 |

The computation of diluted earnings per share attributable to common stockholders excludes stock-based awards that would have had an antidilutive effect on earnings per share. For the three and six months ended June 30, 2025, there were approximately 0.5 million antidilutive shares. For the three and six months ended June 30, 2024, there were approximately 0.2 million antidilutive shares.

Accounts Receivable Securitization Facility
On February 28, 2025, Wesco Distribution amended its accounts receivable securitization facility (the “Receivables Facility”) pursuant to the terms and conditions of a Ninth Amendment to Fifth Amended and Restated Receivables Purchase Agreement (the “Ninth Receivables Amendment”), by and among WESCO Receivables Corp., Wesco Distribution, the various purchasers and purchaser agents party thereto and PNC Bank, National Association, as administrator. The Ninth Receivables Amendment modified the receivables purchase agreement originally entered into on June 22, 2020. The Ninth Receivables Amendment, among other things, extended the scheduled termination date of the Receivables Facility to February 28, 2028, and removed the credit spread adjustment applicable to term SOFR investments. No other material terms were changed.
Revolving Credit Facility
On February 28, 2025, Wesco Distribution amended its revolving credit facility (the “Revolving Credit Facility”) pursuant to the terms and conditions of the Seventh Amendment to Fourth Amended and Restated Credit Agreement (the “Seventh Revolver Amendment”), by and among Wesco Distribution, the other U.S. borrowers party thereto, WESCO Distribution Canada LP, the other Canadian borrowers party thereto, Wesco, the lenders party thereto and Barclays Bank PLC, as administrative agent. The Seventh Revolver Amendment amended the revolving credit agreement originally entered into on June 22, 2020, to, among other things, (i) extend the maturity date of the Revolving Credit Facility to February 28, 2030, (ii) increase the capacity to request increases in the revolving commitments under the Revolving Credit Facility from $450 million to $500 million, (iii) increase certain negative covenant baskets, and (iv) remove the credit spread adjustment applicable to term SOFR and daily simple SOFR loans. No other material terms were changed.
6.375% Senior Notes due 2033
On March 6, 2025, Wesco Distribution issued $800 million aggregate principal amount of 6.375% senior notes due 2033 (the “2033 Notes”). The 2033 Notes were issued at a price of 100% of the aggregate principal amount thereof. Wesco incurred costs related to the issuance of the 2033 Notes totaling $10.3 million, which were recorded as a reduction to the carrying value of the debt and are amortized over the life of the notes.
17

Table of Contents
WESCO INTERNATIONAL, INC. AND SUBSIDIARIES
NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS—(CONTINUED)
(unaudited)
The 2033 Notes were issued pursuant to, and are governed by, an indenture (the “2033 Notes Indenture”), dated as of March 6, 2025, among Wesco Distribution, the Company, Anixter Inc., and U.S. Bank Trust Company, National Association, as trustee (the “Trustee”). The 2033 Notes and related guarantees were issued in a private transaction exempt from the Securities Act of 1933, as amended (the “Securities Act”), and have not been, and will not be, registered under the Securities Act and may not be offered or sold in the United States absent registration or an applicable exemption from, or in a transaction not subject to, the registration requirements of the Securities Act and other applicable securities laws.
The Company used the net proceeds from the issuance of the 2033 Notes to redeem all of the Company’s outstanding Series A Preferred Stock and all of the related depositary shares representing fractional interests in the Series A Preferred Stock in June 2025, and to repay a portion of the amounts outstanding under the Revolving Credit Facility. Prior to redeeming the Series A Preferred Stock, the Company used the net proceeds to temporarily repay all of the outstanding borrowings under its Revolving Credit Facility and to repay a portion of the amounts outstanding under its Receivables Facility. The Company subsequently redrew under the Receivables Facility and the Revolving Credit Facility in an aggregate amount sufficient to redeem the Series A Preferred Stock.
The 2033 Notes are unsecured and unsubordinated obligations of Wesco Distribution and are guaranteed on an unsecured, unsubordinated basis by the Company and Anixter Inc. The 2033 Notes accrue interest at a rate of 6.375% per annum, payable semi-annually in arrears on March 15 and September 15 of each year. The 2033 Notes will mature on March 15, 2033.
Wesco Distribution may redeem all or a part of the 2033 Notes at any time prior to March 15, 2028 by paying a “make-whole” premium plus accrued and unpaid interest, if any, to but excluding the redemption date. In addition, any time prior to March 15, 2028, Wesco Distribution may redeem up to 35% of the original aggregate principal amount of the 2033 Notes with the net cash proceeds from certain equity offerings. At any time between March 15, 2028 and March 14, 2029, Wesco Distribution may redeem all or a part of the 2033 Notes at a redemption price equal to 103.188% of the principal amount. Between March 15, 2029 and March 14, 2030, Wesco Distribution may redeem all or a part of the 2033 Notes at a redemption price equal to 101.594% of the principal amount. On and after March 15, 2030, Wesco Distribution may redeem all or a part of the 2033 Notes at a redemption price equal to 100% of the principal amount.
The 2033 Notes Indenture contains certain covenants that, among other things, limit the Company’s and its restricted subsidiaries’ ability to incur liens on assets, make certain restricted payments, engage in certain sale and leaseback transactions or sell certain assets or merge or consolidate with or into other companies, subject to certain qualifications and exceptions, including the termination of certain of these covenants upon the 2033 Notes receiving investment grade credit ratings.
The 2033 Notes Indenture contains certain events of default, including, among other things, failure to make required payments, failure to comply with certain agreements or covenants, failure to pay or acceleration of certain other indebtedness, certain events of bankruptcy and insolvency, and failure to pay certain judgments. An event of default under the 2033 Notes Indenture will allow either the Trustee or the holders of at least 25% in aggregate principal amount of the series of the then-outstanding 2033 Notes to accelerate or, in certain cases, will automatically cause the acceleration of the amounts due under the 2033 Notes.
10. PENSION PLAN SETTLEMENT
Anixter Inc. sponsored the Anixter Inc. Pension Plan, which was terminated in 2022 and settled in 2024. On February 12, 2024, the remaining benefit obligation of the Anixter Inc. Pension Plan was settled through the purchase of single premium annuity contracts for total cash of $138.8 million. The purchase was funded entirely by the assets of the plan.
During the six months ended June 30, 2024, the Company recognized settlement cost of $5.5 million to recognize unrealized losses previously reported as a component of other comprehensive income (loss) related to the benefit obligation of the Anixter Inc. Pension Plan.
11. FAIR VALUE OF FINANCIAL INSTRUMENTS
The Company’s financial instruments primarily consist of cash and cash equivalents, accounts receivable, accounts payable, bank overdrafts, outstanding indebtedness, foreign currency forward contracts, and benefit plan assets. Except for benefit plan assets, outstanding indebtedness and foreign currency forward contracts, the carrying value of the Company’s other financial instruments approximates fair value.
The assets of the Company’s various defined benefit plans primarily comprise common/collective/pool funds (i.e., mutual funds). These funds are valued at the net asset value (“NAV”) of shares held in the underlying funds. Investments for which fair value is measured using the NAV per share practical expedient are not classified in the fair value hierarchy.
18

Table of Contents
WESCO INTERNATIONAL, INC. AND SUBSIDIARIES
NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS—(CONTINUED)
(unaudited)
The Company uses a market approach to determine the fair value of its debt instruments, utilizing quoted prices in active markets, interest rates and other relevant information generated by market transactions involving similar instruments. Therefore, the inputs used to measure the fair value of the Company’s debt instruments are classified as Level 2 within the fair value hierarchy.
The carrying value of Wesco’s debt instruments with fixed interest rates was $3,875.5 million and $3,074.9 million as of June 30, 2025 and December 31, 2024, respectively. The estimated fair value of this debt was $3,984.9 million and $3,127.3 million as of June 30, 2025 and December 31, 2024, respectively. The reported carrying values of Wesco’s other debt instruments, including those with variable interest rates, approximated their fair values as of June 30, 2025 and December 31, 2024.
The Company purchases foreign currency forward contracts to reduce the effect of fluctuations in foreign currency-denominated accounts on its earnings. The foreign currency forward contracts are not designated as hedges for accounting purposes. The Company’s strategy is to negotiate terms for its derivatives and other financial instruments to be highly effective, such that the change in the value of the derivative offsets the impact of the underlying hedge. Its counterparties to foreign currency forward contracts have investment-grade credit ratings. The Company regularly monitors the creditworthiness of its counterparties as a risk mitigation effort to protect the value of its derivatives.
The Company does not hedge 100% of its foreign currency-denominated accounts. In addition, the results of hedging can vary significantly based on various factors, such as the timing of executing foreign currency forward contracts versus the movement of currencies, as well as fluctuations in the account balances throughout each reporting period. The fair value of foreign currency forward contracts is based on the difference between the contract rate and the current price of a forward contract with an equivalent remaining term. The fair value of foreign currency forward contracts is measured using observable market information. These inputs are considered Level 2 in the fair value hierarchy. At June 30, 2025 and December 31, 2024, foreign currency forward contracts were revalued at then-current foreign exchange rates with the changes in valuation reflected directly in other non-operating expense (income) in the Condensed Consolidated Statements of Income and Comprehensive Income offsetting the transaction gain (loss) recorded on foreign currency-denominated accounts. The gross and net notional amounts of foreign currency forward contracts outstanding were approximately $414.8 million and $345.7 million, at June 30, 2025 and December 31, 2024, respectively. While all of the Company’s foreign currency forward contracts are subject to master netting arrangements with its counterparties, assets and liabilities related to these contracts are presented on a gross basis within the Condensed Consolidated Balance Sheets. The gross fair value of assets and liabilities related to foreign currency forward contracts were immaterial.
12. COMMITMENTS AND CONTINGENCIES
From time to time, a number of lawsuits and claims have been or may be asserted against the Company relating to the conduct of its business, including litigation relating to commercial, product and employment matters. The outcome of any litigation cannot be predicted with certainty, and some lawsuits may be determined adversely to Wesco. However, management does not believe that the ultimate outcome of any such pending matters is likely to have a material adverse effect on Wesco’s financial condition or liquidity, although the resolution in any fiscal period of one or more of these matters may have a material adverse effect on Wesco’s results of operations for that period.
13. INCOME TAXES
The effective tax rate for the three months ended June 30, 2025 and 2024 was 26.1% and 27.4%, respectively. For the three months ended June 30, 2025 and 2024, the effective tax rate reflects discrete income tax benefits of $0.3 million and $0.7 million, respectively, resulting from the exercise and vesting of stock-based awards. These discrete income tax benefits reduced the effective tax rates in the respective periods by approximately 0.1 and 0.2 percentage points.
The effective tax rate for the six months ended June 30, 2025 and 2024 was 25.0% and 25.4%, respectively. For the six months ended June 30, 2025 and 2024, the effective tax rates reflect discrete income tax benefits of $5.0 million and $8.5 million, respectively, resulting from the exercise and vesting of stock-based awards. These discrete income tax benefits reduced the effective tax rates in the respective periods by approximately 1.3 and 1.8 percentage points.
During the first six months of 2025, the Company purchased $54.4 million of transferable clean energy tax credits. The Company used $53.3 million of these tax credits to reduce its 2024 U.S. federal income tax liability and $1.1 million to reduce its 2025 U.S. federal income tax liability. The Company has taken appropriate measures to mitigate the transferee liability associated with these tax credits, including but not limited to conducting due diligence to confirm the eligibility of the underlying projects or production, as applicable, for the tax credits and the eligibility of the tax credits for transfer, obtaining appropriate contractual protections from the sellers, and obtaining tax credit insurance.

WESCO INTERNATIONAL, INC. AND SUBSIDIARIES
NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS—(CONTINUED)
(unaudited)
The effective tax rate, excluding discrete income tax benefits, differs from the federal statutory income tax rate due primarily to state income taxes, nondeductible expenses, and the tax impact of international operations.
There have been no material adjustments to the Company's assessment of uncertain tax positions since December 31, 2024.
On July 4, 2025, the U.S. enacted H.R. 1, commonly referred to as the One Big Beautiful Bill Act (“OBBBA”) into law. The OBBBA makes permanent certain expiring provisions of the 2017 Tax Cuts and Jobs Act (“TCJA”) and modifies other provisions of the TCJA and the Inflation Reduction Act. The OBBBA contains various effective dates with certain provisions effective in 2025 and others effective in 2026 and beyond. Accounting Standards Codification (“ASC”) 740, Income Taxes, requires the impact of changes in tax laws (or rates) to be recognized in the financial statements as of the date of enactment, which is when all legislative steps necessary for the bill to become law are complete. Consequently, there is no impact from the OBBBA reflected in our financial statements for the current period. We are currently evaluating the impact of the OBBBA tax law changes and will reflect the impact in future financial statements, which include the date of enactment. At this time, we do not expect the provisions of the OBBBA to materially impact the 2025 effective tax rate.
14. BUSINESS SEGMENTS
The Company has operating segments comprising three strategic business units: EES, CSS and UBS. These operating segments are equivalent to the Company’s reportable segments. The President and Chief Executive Officer serves as the Company’s Chief Operating Decision Maker (“CODM”). The CODM evaluates the performance of the Company’s reportable segments based on adjusted earnings before interest, taxes, depreciation and amortization (“adjusted EBITDA”), which is the Company’s measure of segment profit or loss.
The Company incurs corporate costs primarily related to treasury, tax, information technology, legal and other centralized functions. The Company also has various corporate assets. Segment assets may not include jointly used assets, but segment results include depreciation expense or other allocations related to those assets. Interest expense and other non-operating items are either not allocated to the segments or reviewed on a segment basis. Corporate expenses and assets not directly identifiable with a reportable segment are reported in the tables below to reconcile the reportable segments to the consolidated financial statements.
As previously described in Note 2, “Accounting Policies,” the reportable segment information for the three and six months ended June 30, 2024 for the EES and CSS reportable segments has been recast to conform to the current year presentation.
The following tables present information about the Company’s reportable segments and reconcile adjusted EBITDA by segment to income before income taxes on a consolidated basis for the periods presented:

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations.
The following discussion should be read in conjunction with the unaudited condensed consolidated financial statements and notes thereto included in Item 1 of this Quarterly Report on Form 10-Q and WESCO International, Inc.’s audited Consolidated Financial Statements and Management’s Discussion and Analysis of Financial Condition and Results of Operations included in its Annual Report on Form 10-K for the fiscal year ended December 31, 2024. The matters discussed herein may contain forward-looking statements that are subject to certain risks and uncertainties that could cause actual results to differ materially from expectations. Certain of these risks are set forth in Item 1A of WESCO International, Inc.’s Annual Report on Form 10-K for the fiscal year ended December 31, 2024, as well as WESCO International, Inc.’s other reports filed with the Securities and Exchange Commission. In this Item 2, “Wesco” refers to WESCO International, Inc., and its subsidiaries and its predecessors unless the context otherwise requires. References to “we,” “us,” “our” and the “Company” refer to Wesco and its subsidiaries.
In addition to the results provided in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”), our discussion and analysis of financial condition and results of operations includes certain non-GAAP financial measures, which are defined further below. These financial measures include organic sales growth, earnings before interest, taxes, depreciation and amortization (“EBITDA”), adjusted EBITDA, adjusted EBITDA margin, financial leverage, adjusted selling, general and administrative expenses, adjusted income from operations, adjusted other non-operating expense (income), adjusted provision for income taxes, adjusted income before income taxes, adjusted net income, adjusted net income attributable to WESCO International, Inc., adjusted net income attributable to common stockholders, and adjusted earnings per diluted share. We believe that these non-GAAP measures are helpful to users of our financial statements as they provide a better understanding of our financial condition and results of operations on a comparable basis. Additionally, certain non-GAAP measures either focus on or exclude items impacting comparability of results, allowing users to more easily compare our financial performance from period to period. Management uses certain non-GAAP financial measures in its evaluation of the performance of the Company’s operating segments and in the determination of incentive compensation. Management does not use these non-GAAP financial measures for any purpose other than the reasons stated above.
Company Overview
Wesco, headquartered in Pittsburgh, Pennsylvania, is a leading provider of business-to-business distribution, logistics services and supply chain solutions.
We employ approximately 20,000 people, maintain relationships with more than 35,000 suppliers, and serve nearly 140,000 customers worldwide. With millions of products, end-to-end supply chain services, and leading digital capabilities, Wesco provides innovative solutions to meet customer needs across commercial and industrial businesses, contractors, educational institutions, government agencies, technology companies, telecommunications providers, and utilities. Our innovative solutions include supply chain management, logistics and transportation, procurement, warehousing and inventory management, as well as kitting and labeling, limited assembly of products and installation enhancement. We operate more than 700 sites, including distribution centers, fulfillment centers, and sales offices, in approximately 50 countries, providing a local presence for customers and a global network to serve multi-location businesses and global corporations.
We have operating segments comprising three strategic business units: Electrical & Electronic Solutions (“EES”), Communications & Security Solutions (“CSS”) and Utility & Broadband Solutions (“UBS”). These operating segments are equivalent to our reportable segments. The following is a description of each of our reportable segments and their business activities.
Electrical & Electronic Solutions
The EES segment, serving customers in over 50 countries, is a North American leader, and supplies a broad range of products and solutions primarily to construction, industrial and original equipment manufacturer (“OEM”) customers. The EES product portfolio includes a broad range of electrical equipment and supplies, automation and connected devices (the “Internet of Things” or “IoT”), security, lighting, wire and cable, safety, and maintenance, repair and operating (“MRO”) products from industry-leading manufacturing partners. The EES service portfolio includes solutions to improve project execution, direct and indirect manufacturing supply chain optimization programs, lighting and renewables advisory services, and digital and automation solutions to improve safety and productivity.

WESCO INTERNATIONAL, INC. AND SUBSIDIARIES
Communications & Security Solutions
The CSS segment, serving customers in over 50 countries, is a global leader in data center, enterprise network infrastructure and security solutions. CSS sells directly to end-users or through an extensive network of channel partners, including data communications contractors, security and network integrators, professional audio/visual integrators, and systems integrators. CSS also provides a wide range of professional A/V, safety, facilities, and energy management solutions. The full CSS product portfolio is frequently coupled with services designed to enhance efficiency and productivity across all customer segments globally. These services include data center services, advisory, installation enhancement, project deployment, supply chain solutions, and management platforms.
Utility & Broadband Solutions
The UBS segment is a leader in North America, serving customers primarily in the U.S. and Canada, and provides products and services to investor-owned utilities, public power companies, including municipalities, as well as global service providers, wireless providers, broadband operators and the contractors that service these customers. The products sold include wire and cable, transformers, transmission and distribution hardware, switches, protective devices, connectors, lighting, conduit, fiber and copper cable, connectivity products, pole line hardware, racks, cabinets, safety and MRO products, and point-to-point wireless devices. UBS also offers a complete set of service solutions to improve customer supply chain efficiencies.
Business Highlights
Despite uncertainty and volatility persisting in the market, our financial results reflect continued sales momentum in the second quarter of 2025. Our financial results for the first six months of 2025 compared to the first six months of 2024 reflect an increase in reported sales of 3.8%, and as adjusted for mergers & acquisitions activity, fluctuations in foreign exchange rates and number of workdays, an increase in organic sales of 6.4%. Our data center business is primarily driving this growth in sales, but also contributing to lower gross margins as compared to prior year, as there have been several large project wins at lower margins. We saw weakness in the utility business within UBS, as expected, due to ongoing customer destocking and cautious spending related to tariff and market uncertainties. However, utility has begun to show signs of improvement as sales to investor-owned utilities returned to growth in the second quarter of 2025.
As of June 22, 2025, we redeemed all outstanding shares of our Series A Preferred Stock for $540.3 million. As a result of the transaction, the Company recorded a $27.6 million gain recognized as income attributable to common stockholders. The redemption was funded with the net proceeds from our 6.375% senior notes due 2033, which we issued in the first quarter of 2025. This redemption reduced our total financing costs and creates ongoing net income, EPS, and cash flow benefits. Following this redemption, we have no significant debt maturities until 2028 and have strong liquidity to execute our capital allocation priorities of debt reduction, stock buybacks and acquisitions.
We continued our approach to addressing supplier price increases in response to global tariffs enacted by the United States under the International Emergency Economic Powers Act of 1977, including but not limited to, passing through price increases, leveraging scale to provide locally sourced products, reducing imports from high tariff countries, optimizing supply chain logistics, and re-engineering our global supply chain.
During the second quarter of 2025, we continued to execute on our multi-year, phased development and implementation of a new Digital and Data Platform (“DDP”). The DDP is intended to be a unified, technology-enabled operating model that spans all business functions, maintains and enhances the flow of financial information, and improves resource efficiency.
Taking the above highlights into consideration, we believe we are well positioned to benefit from enduring secular growth trends of AI-driven data centers, increased power generation, electrification, automation, and reshoring.

Results of Operations
Second Quarter of 2025 versus Second Quarter of 2024
Net Sales
The following table sets forth net sales and organic sales growth for the periods presented:

| Three Months Ended |  | Growth/(Decline)
| June 30, 2025 |  | June 30, 2024 |  | Reported Sales |  | Acquisition |  | Foreign Exchange |  | Workday |  | Organic Sales
| (In millions) |  |  |  |  |  |  |  |  |  |
Net sales | $ | 5,899.6 |  |  | $ | 5,479.7 |  |  | 7.7 | % |  | 0.5 | % |  | — | % |  | — | % |  | 7.2 | %

Note: Organic sales growth is a non-GAAP financial measure of sales performance. Organic sales growth is calculated by deducting the percentage impact from acquisitions and divestitures for one year following the respective transaction, fluctuations in foreign exchange rates and number of workdays from the reported percentage change in consolidated net sales. Workday impact represents the change in the number of operating days period-over-period after adjusting for weekends and public holidays in the United States; there was no change in the number of workdays in the second quarter of 2025 compared to the second quarter of 2024.
Net sales were $5.9 billion for the second quarter of 2025 compared to $5.5 billion for the second quarter of 2024, an increase of 7.7%. Adjusting for the increase from the acquisition of Ascent, organic sales for the second quarter of 2025 grew by 7.2%. This growth is reflective of an approximate 6% increase in volume, driven by volume increases in the CSS and EES segments, partially offset by a decline in the UBS segment, and by the impact of changes in price, which favorably impacted consolidated organic sales by approximately 1%.
Cost of Goods Sold
Cost of goods sold for the second quarter of 2025 was $4.7 billion compared to $4.3 billion for the second quarter of 2024, an increase of 8.8%. Cost of goods sold as a percentage of net sales was 78.9% and 78.1% for the second quarter of 2025 and 2024, respectively. The unfavorable increase of 80 basis points reflects a decrease in gross margin in all three segments, which is inclusive of higher inventory adjustments, partially offset by higher supplier volume rebates.
Selling, General and Administrative Expenses
Selling, general and administrative (“SG&A”) expenses for the second quarter of 2025 totaled $872.2 million versus $828.4 million for the second quarter of 2024, an increase of $43.8 million, or 5.3%.
The following table reconciles SG&A expenses to adjusted SG&A expenses, which is a non-GAAP financial measure, for the periods presented:

| Three Months Ended
| June 30, 2025 | % of net sales | June 30, 2024 | % of net sales
Adjusted SG&A Expenses: | (In millions)
Selling, general and administrative expenses | $ | 872.2 | 14.8% | $ | 828.4 | 15.1%
Digital transformation costs(1) | (7.6) |  | (6.1) |
Restructuring costs(2) | (0.5) |  | (0.9) |
Loss on abandonment of assets(3) | — |  | (17.8) |
Adjusted selling, general and administrative expenses | $ | 864.1 | 14.6% | $ | 803.6 | 14.7%

(1) Digital transformation costs include costs associated with certain digital transformation initiatives.
(2) Restructuring costs include severance costs incurred pursuant to an ongoing restructuring plan.
(3) Loss on abandonment of assets represents the write-off of certain capitalized cloud computing arrangement implementation costs relating to a third-party developed operations management software product in favor of an application with functionality that better suits the Company’s operations.
SG&A payroll and payroll-related expenses for the second quarter of 2025 of $541.5 million increased by $34.9 million compared to the same period in 2024 primarily as a result of an increase of $28.3 million in salaries and $9.6 million in benefits, partially offset by a decrease of $3.0 million in commissions and incentives.

Table of Contents
WESCO INTERNATIONAL, INC. AND SUBSIDIARIES
SG&A expenses not related to payroll and payroll-related costs for the second quarter of 2025 were $330.7 million, an increase of $8.9 million compared to the same period in 2024, which primarily reflects higher costs to operate our facilities of $9.2 million, higher transportation costs of $8.2 million, higher IT costs of $5.4 million, and higher employee expenses of $2.9 million. These increases were partially offset by a $17.1 million decrease in other income and deductions, primarily attributable to the loss on abandonment of assets in the second quarter of 2024 as discussed above.
Income from Operations
Income from operations was $322.2 million for the second quarter of 2025 compared to $323.5 million for the second quarter of 2024, a decrease of $1.3 million, or 0.4%.
Interest Expense, net
Net interest expense totaled $92.9 million for the second quarter of 2025 compared to $98.8 million for the second quarter of 2024. The decrease of $5.9 million, or 6.0%, was primarily driven by lower interest rates on the Receivables Facility as well as lower borrowings and lower interest rates on the Revolving Credit Facility, partially offset by higher borrowings on the Receivables Facility throughout the second quarter of 2025 compared to the second quarter of 2024 due to the impact of the WIS divestiture on outstanding borrowings and increased working capital investments.
Other Income, net
Other non-operating income totaled $7.3 million for the second quarter of 2025 compared to $95.9 million for the second quarter of 2024. We recognized a net foreign currency exchange gain of $3.0 million for the second quarter of 2025 compared to a net foreign currency exchange loss of $3.4 million for the second quarter of 2024. We recognized $2.3 million of income in the second quarter of 2025 from an adjustment to the fair value of the contingent consideration liability related to the entroCIM acquisition. We recognized net benefits of $0.8 million and $0.4 million associated with the non-service cost components of net periodic pension (benefit) cost for the three months ended June 30, 2025 and 2024, respectively.
The following table reconciles other non-operating income to adjusted other non-operating (income) expense, which is a non-GAAP financial measure, for the periods presented:

| Three Months Ended
| June 30, 2025 |  | June 30, 2024
Adjusted Other (Income) Expense, net: | (In millions)
Other income, net | $ | (7.3) |  | $ | (95.9)
Gain on divestiture(1) | — |  | 102.9
Loss on termination of business arrangement(2) | — |  | (3.8)
Adjusted other (income) expense, net | $ | (7.3) |  | $ | 3.2

(1) Gain on divestiture represents the gain recognized as a result of the divestiture of the Wesco Integrated Supply (“WIS”) business on April 1, 2024.
(2) Loss on termination of business arrangement represents the loss recognized as a result of management's decision to terminate a business arrangement with a third party.
Income Taxes
The provision for income taxes was $61.8 million for the second quarter of 2025 compared to $87.8 million for the corresponding quarter of the prior year, resulting in effective tax rates of 26.1% and 27.4%, respectively. The lower effective tax rate for the second quarter of 2025 is due to a higher provision for income taxes related to uncertain tax positions in the prior year period.
Net Income and Earnings per Share
Net income and earnings per diluted share attributable to common stockholders were $189.2 million and $3.83, respectively, for the second quarter of 2025 compared to $217.7 million and $4.28, respectively, for the second quarter of 2024. Adjusted for the non-GAAP adjustments above and the related income tax effects, and the $27.6 million gain recognized as a result of the Company's redemption of its outstanding Series A Preferred Stock, net income and earnings per diluted share attributable to common stockholders were $167.5 million and $3.39, respectively, for the three months ended June 30, 2025 and $163.5 million and $3.21, respectively, for the three months ended June 30, 2024.
29

Table of Contents
WESCO INTERNATIONAL, INC. AND SUBSIDIARIES
The increase in adjusted earnings per diluted share primarily reflects the increase in net sales and the decrease in interest expense, as discussed above, partially offset by the increase in cost of goods sold as a percentage of net sales, an increase in SG&A expenses, and the decrease in other income. Additionally, there was a positive impact from the reduction in outstanding shares during the second quarter of 2025 as compared to the second quarter of 2024.
Adjusted EBITDA
Adjusted EBITDA, a non-GAAP financial measure, was $394.2 million for the second quarter of 2025, compared to $400.1 million for the second quarter of 2024, a decrease of $5.9 million, or 1.5% year-over-year. The decrease primarily reflects a $375.2 million increase in cost of goods sold related to increased large project sales with lower margins, and a $43.8 million increase in SG&A expenses, as described above, partially offset by an increase in net sales.

The following is a discussion of the financial results of our operating segments comprising three strategic business units consisting of EES, CSS and UBS for the three months ended June 30, 2025. As further described below and in Note 14, “Business Segments” of our Notes to the unaudited Condensed Consolidated Financial Statements, the Chief Operating Decision Maker (the “CODM”) allocates resources and evaluates the performance of the Company’s reportable segments based on adjusted EBITDA, which is the Company’s measure of segment profit or loss. Adjusted EBITDA and adjusted EBITDA margin percentage are non-GAAP financial measures. As previously described in Note 2, “Accounting Policies,” the reportable segment information for the three months ended June 30, 2024 for the EES and CSS reportable segments has been recast to conform to the current year presentation.

EES reported net sales of $2.3 billion for the second quarter of 2025 compared to $2.1 billion for the second quarter of 2024, an increase of $123.3 million, or 5.8%. EES organic sales for the second quarter of 2025 grew by 6.0%, driven primarily by volume growth of approximately 5%, as well as the impact of changes in price, which favorably impacted organic sales by approximately 1%.
EES adjusted EBITDA decreased $7.3 million, or 3.8% year-over-year. The decrease primarily reflects lower margin project activity and product mix, partially offset by an increase in volume. Additionally, SG&A expenses increased $14.1 million as compared to the prior year, which was primarily attributed to an increase in salaries of $7.1 million and an increase in transportation costs of $3.6 million.

CSS reported net sales of $2.3 billion for the second quarter of 2025 compared to $1.9 billion for the second quarter of 2024, an increase of $360.9 million, or 19.0%, which is inclusive of a favorable impact from the acquisition of Ascent of 1.5%. CSS organic sales for the second quarter of 2025 grew by 17.3%, primarily reflecting volume growth of approximately 15%, driven primarily by growth in the data center solutions business, as well as the impact of changes in price, which favorably impacted organic sales by approximately 2%.

CSS adjusted EBITDA increased $43.4 million, or 27.9% year-over-year. The increase primarily reflects an increase in volume, specifically within the data center solutions business, as described above, partially offset by an increase in SG&A expenses of $18.2 million. The increase in SG&A expenses is primarily attributed to a $5.8 million increase in transportation costs consistent with higher sales, increased salaries of $5.7 million, increased commissions and incentives of $3.0 million, higher benefits of $2.7 million, and increased operations expenses of $2.3 million.

UBS reported net sales of $1,376.6 million for the second quarter of 2025 compared to $1,440.9 million for the second quarter of 2024, a decrease of $64.3 million, or 4.5%. UBS organic sales for the second quarter of 2025 declined by 4.4%, reflecting volume declines, primarily as a result of ongoing customer destocking and cautious spending related to tariff and market uncertainties. Changes in price did not have a material impact on the year-over-year decline in UBS organic sales.
UBS adjusted EBITDA decreased $29.8 million, or 17.2% year-over-year. The decrease primarily reflects a decline in volume, as described above. SG&A expenses increased $5.5 million as compared to the prior year, primarily due to higher costs to operate our facilities of $5.0 million.

Six Months Ended June 30, 2025 versus Six Months Ended June 30, 2024
Net Sales
The following table sets forth net sales and organic sales growth for the periods presented:

| Six Months Ended |  | Growth/(Decline)
| June 30, 2025 |  | June 30, 2024 |  | Reported Sales |  | Acquisition/Divestiture |  | Foreign Exchange |  | Workday |  | Organic Sales
| (In millions) |  |  |  |  |  |  |  |  |  |
Net sales | $ | 11,243.3 |  |  | $ | 10,829.7 |  |  | 3.8 | % |  | (1.2) | % |  | (0.6) | % |  | (0.8) | % |  | 6.4 | %

Note: Organic sales growth is a non-GAAP financial measure of sales performance. Organic sales growth is calculated by deducting the percentage impact from acquisitions and divestitures for one year following the respective transaction, fluctuations in foreign exchange rates and number of workdays from the reported percentage change in consolidated net sales. Workday impact represents the change in the number of operating days period-over-period after adjusting for weekends and public holidays in the United States; the first six months of 2025 had one less workday compared to the first six months of 2024.
Net sales were $11.2 billion for the first six months of 2025 compared to $10.8 billion for the first six months of 2024, an increase of 3.8%. Adjusting in part for the 1.2% net decrease from the divestiture of the WIS business and the acquisition of Ascent, organic sales for the first six months of 2025 grew by 6.4%. This growth is reflective of an approximate 5% increase in volume, driven by growth in the CSS and EES segments, partially offset by a decline in the UBS segment, and the impact of changes in price, which favorably impacted consolidated organic sales by approximately 1%.
Cost of Goods Sold
Cost of goods sold for the first six months of 2025 was $8.9 billion compared to $8.5 billion for the first six months of 2024, an increase of 4.5%. Cost of goods sold as a percentage of net sales was 78.9% and 78.4% for the first six months of 2025 and 2024, respectively. The unfavorable increase of 50 basis points primarily reflects a decrease in gross margin in all three segments, which is inclusive of higher inventory adjustments, partially offset by higher supplier volume rebates.
Selling, General and Administrative Expenses
SG&A expenses for the first six months of 2025 totaled $1,708.5 million versus $1,657.8 million for the first six months of 2024, an increase of $50.7 million, or 3.1%.
The following table reconciles SG&A expenses to adjusted SG&A expenses, which is a non-GAAP financial measure, for the periods presented:

| Six Months Ended
| June 30, 2025 | % of net sales | June 30, 2024 | % of net sales
Adjusted SG&A Expenses: | (In millions)
Selling, general and administrative expenses | $ | 1,708.5 | 15.2% | $ | 1,657.8 | 15.3%

Adjusted selling, general and administrative expenses | $ | 1,693.1 | 15.1% | $ | 1,614.1 | 14.9%

(1) Digital transformation costs include costs associated with certain digital transformation initiatives.
(2) Restructuring costs include severance costs incurred pursuant to an ongoing restructuring plan.
(3) Loss on abandonment of assets represents the write-off of certain capitalized cloud computing arrangement implementation costs relating to a third-party developed operations management software product in favor of an application with functionality that better suits the Company’s operations.
(4) Excise taxes on excess pension plan assets represent the excise taxes applicable to the excess pension plan assets following the final settlement of the Company's U.S. pension plan.

WESCO INTERNATIONAL, INC. AND SUBSIDIARIES
SG&A payroll and payroll-related expenses for the first six months of 2025 of $1,060.9 million increased by $30.1 million compared to the same period in 2024 primarily as a result of higher salaries of $28.4 million due to wage inflation, partially offset by the impact of the divestiture of the WIS business, and higher benefits expense of $8.5 million, partially offset by lower commissions and incentive compensation expenses of $6.2 million.
SG&A expenses not related to payroll and payroll-related costs for the first six months of 2025 were $647.6 million, an increase of $20.5 million compared to the same period in 2024, which primarily reflects higher costs to operate our facilities of $16.1 million, higher transportation costs of $15.0 million, and higher IT costs of $6.5 million, partially offset by a decrease of $15.5 million in other income and deductions, primarily attributable to the loss on abandonment of assets in the second quarter of 2024 as discussed above.
Income from Operations
Income from operations was $563.1 million for the first six months of 2025 compared to $586.5 million for the first six months of 2024. The decrease of $23.4 million, or 4.0%, reflects an increase in sales exceeded by higher cost of goods sold as a percentage of net sales due to a decrease in gross margin in all three segments, as well as an increase in SG&A expenses, as described above.
Interest Expense, net
Net interest expense totaled $179.2 million for the first six months of 2025 compared to $193.2 million for the first six months of 2024. The decrease of $14.0 million, or 7.2%, primarily reflects lower borrowings on the Receivables Facility and the Revolving Credit Facility, partly driven by repayment from refinancing activity related to the issuance of the 2029, 2032, and 2033 Notes, as well as lower interest rates on both facilities.
Other Income, net
Other non-operating income totaled $7.1 million for the first six months of 2025 compared to $74.3 million for the first six months of 2024. We recognized $2.4 million of income in the first six months of 2025 from an adjustment to the fair value of the contingent consideration liability related to the entroCIM acquisition. Due to fluctuations in the U.S. dollar against certain foreign currencies, we recognized a net foreign currency exchange gain of $1.9 million for the first six months of 2025 compared to a net loss of $20.7 million for the first six months of 2024. We recognized net benefits of $1.6 million and net costs of $5.5 million associated with the non-service cost components of net periodic pension cost (benefit) for the six months ended June 30, 2025 and 2024, respectively. The year-over-year decrease in net periodic pension costs was due to pension settlement cost to recognize unrealized losses previously reported as a component of other comprehensive income (loss) related to the benefit obligation of the Anixter Inc. Pension Plan as a result of the final settlement of the plan in the first quarter of 2024.
The following table reconciles other non-operating income to adjusted other non-operating (income) expense, which is a non-GAAP financial measure, for the periods presented:

| Six Months Ended

Loss on termination of business arrangement(1) | (0.3) |  | (3.8)
Pension settlement cost(2) | — |  | (5.5)
Gain on divestiture(3) | — |  | 102.9
Adjusted other (income) expense, net | $ | (7.4) |  | $ | 19.3

(1) Loss on termination of business arrangement represents the loss recognized as a result of management's decision to terminate a business arrangement with a third party.
(2) Pension settlement cost represents expense related to the final settlement of the Company's U.S. pension plan.
(3) Gain on divestiture represents the gain recognized as a result of the divestiture of the Wesco Integrated Supply (“WIS”) business on April 1, 2024.
Income Taxes
The provision for income taxes was $97.9 million for the first six months of 2025 compared to $118.7 million in last year's comparable period, resulting in effective tax rates of 25.0% and 25.4%, respectively.

Net Income and Earnings per Share
Net income and earnings per diluted share attributable to common stockholders were $293.2 million and $5.92, respectively, for the first six months of 2025 compared to $319.2 million and $6.22, respectively, for the first six months of 2024. Adjusted for the non-GAAP adjustments above and the related income tax effects, and the $27.6 million gain recognized as a result of the Company's redemption of its outstanding Series A Preferred Stock, net income and earnings per diluted share attributable to common stockholders were $277.2 million and $5.60, respectively, for the first six months of 2025 and $282.9 million and $5.51, respectively, for the first six months of 2024.
The increase in adjusted earnings per diluted share primarily reflects the increase in net sales as well as the decrease in interest expense, as discussed above, partially offset by the increase in cost of goods sold as a percentage of net sales, the decrease in other income, and the increase in SG&A expenses. Additionally, there was a positive impact from the reduction in outstanding shares during the first six months of 2025 as compared to the first six months of 2024.
Adjusted EBITDA
Adjusted EBITDA, a non-GAAP financial measure, was $704.9 million for the first six months of 2025 compared to $740.5 million for the first six months of 2024, a decrease of $35.6 million, or 4.8% year-over-year. The decrease primarily reflects a $381.2 million increase in cost of goods sold, and a $50.7 million increase in SG&A expenses, as described above, partially offset by a $413.6 million increase in net sales. Included in the increase in SG&A expenses was a $17.8 million increase from the absence of asset abandonment loss in first six months of 2025 compared to the first six months of 2024, and a $4.8 million increase from the absence of excise taxes on excess pension plan assets in first six months of 2025 compared to the first six months of 2024. Additionally, there was a year-over-year decrease in restructuring costs of $7.4 million. All three items are adjustments to calculate adjusted EBITDA.

EES reported net sales of $4.3 billion for the first six months of 2025 compared to $4.2 billion for the first six months of 2024, an increase of $124.3 million, or 3.0%. EES organic sales for the first six months of 2025 grew by 4.7%, driven primarily by volume growth of approximately 3%, primarily as a result of growth in the original equipment manufacturers business, and by the impact of changes in price, which favorably impacted organic sales by approximately 2%.
EES adjusted EBITDA decreased $26.4 million, or 7.5% year-over-year. The decrease primarily reflects an unfavorable change in product mix, partially offset by an increase in volume and price, as described above. Additionally, SG&A expenses increased $21.1 million as compared to the prior year, which was primarily attributed to an increase in salaries of $8.2 million, an increase in transportation costs of $6.0 million, an increase in operations expenses of $4.0 million, and an increase in bad debt expense of $3.0 million, partially offset by lower commissions and incentives of $3.5 million.

CSS reported net sales of $4.3 billion for the first six months of 2025 compared to $3.6 billion for the first six months of 2024, an increase of $656.4 million, or 18.2%, which is inclusive of a favorable impact from the acquisition of Ascent of 1.9%. CSS organic sales for the first six months of 2025 grew by 17.7%, driven primarily by volume growth of approximately 17% as a result of growth in the data center solutions business and less significant growth in the security solutions business, partially offset by volume decline in the enterprise network infrastructure business, and by the impact of changes in price, which favorably impacted organic sales by approximately 1%.
CSS adjusted EBITDA increased $70.6 million, or 24.6% year-over-year. The increase reflects an increase in volume, specifically within the data center solutions business and the security solutions business, as described above. Further, there was an increase in SG&A expenses of $38.9 million. The increase in SG&A expenses is primarily attributed to higher transportation costs of $12.7 million consistent with higher sales, higher salaries of $9.8 million, higher commissions and incentives of $6.6 million, and higher benefits expense of $6.0 million.

UBS reported net sales of $2.7 billion for the first six months of 2025 compared to $3.0 billion for the first six months of 2024, a decrease of $367.1 million, or 12.1%, which is inclusive of an unfavorable impact from the divestiture of the WIS business of 6.3%. UBS organic sales for the first six months of 2025 declined by 4.7%, reflecting volume declines, primarily as a result of ongoing customer destocking and cautious spending related to tariff and market uncertainties. Changes in price did not have a material impact on the year-over-year decline in UBS organic sales.
UBS adjusted EBITDA decreased $60.9 million, or 17.8% year-over-year. The decrease primarily reflects a decline in volume, as described above. The decrease in adjusted EBITDA was further offset by a decrease in SG&A expenses of $12.3 million as compared to the prior year, which was primarily attributed to lower salaries of $4.8 million, lower commissions and incentives of $4.7 million, and lower benefits expense of $2.4 million, all of which were driven by the impact of the WIS divestiture.

Liquidity and Capital Resources
Our liquidity needs generally arise from fluctuations in our working capital requirements, information technology investments, capital expenditures, acquisitions, the payment of dividends, and debt service obligations. As of June 30, 2025, we had approximately $1.2 billion in available borrowing capacity under our Revolving Credit Facility, after giving effect to outstanding letters of credit and certain borrowings under our international lines of credit, and $250.0 million of available borrowing capacity under our Receivables Facility, which combined with available cash of $350.5 million, provided liquidity of approximately $1.8 billion. Cash included in our determination of liquidity represents cash in certain deposit and interest-bearing investment accounts held in the United States and Canada. We monitor the depository institutions that hold our cash and cash equivalents on a regular basis, and we believe that we have placed our deposits with creditworthy financial institutions.
As described in Note 9, “Debt” of our Notes to the unaudited Condensed Consolidated Financial Statements, on March 6, 2025, Wesco Distribution issued $800 million aggregate principal amount of 6.375% senior notes due 2033 (the “2033 Notes”). We used the net proceeds from the issuance of the 2033 Notes to redeem all of the Company’s outstanding Series A Preferred Stock and all of the related depositary shares representing fractional interests in the Series A Preferred Stock in June 2025, and to repay a portion of the amounts outstanding under the Revolving Credit Facility. Prior to redeeming the Series A Preferred Stock, we used the net proceeds to temporarily repay all of the outstanding borrowings under our Revolving Credit Facility and to repay a portion of the amounts outstanding under our Receivables Facility. We subsequently redrew under the Receivables Facility and the Revolving Credit Facility in an aggregate amount sufficient to redeem the Series A Preferred Stock.
We regularly review our mix of fixed versus variable rate debt, and we may, from time to time, issue or retire borrowings and/or refinance existing debt in an effort to mitigate the impact of interest rate and foreign exchange rate fluctuations, and to maintain a cost-effective capital structure consistent with our anticipated capital requirements. Interest rates remained stable in the first six months of 2025 after the Federal Reserve reduced its benchmark interest rate by a total of 100 basis points in the second half of 2024. Future interest rate changes would raise or lower the rates we pay on our variable rate debt and would contribute to fluctuations in interest expense versus prior periods.
As of June 30, 2025, approximately 68% of our debt portfolio consisted of fixed rate debt. We believe our capital structure has an appropriate mix of fixed versus variable rate debt and secured versus unsecured instruments.
Over the next several quarters, we expect that our excess liquidity will be directed primarily at share repurchases, the payment of dividends, debt reduction, digital transformation initiatives, and potential acquisitions and related integration activities. We expect to maintain sufficient liquidity through our credit facilities and cash balances. We continue to monitor the sufficiency of our liquidity given the potential impact of current economic conditions and uncertainty, including tariffs, interest rates, and inflation. While we did not face significant challenges with our sources or uses of cash in the first six months of 2025, future market disruptions could occur which could potentially affect our liquidity. We believe cash provided by operations and financing activities will be adequate to cover our operational and business needs for at least the next twelve months.
We communicate on a regular basis with our lenders regarding our financial and working capital performance, and liquidity position. We were in compliance with all financial covenants and restrictions contained in our debt agreements as of June 30, 2025.
We also measure our ability to meet our debt obligations based on our financial leverage ratio, which was 3.4x as of June 30, 2025 and 2.9x as of December 31, 2024.

WESCO INTERNATIONAL, INC. AND SUBSIDIARIES
Most of the undistributed earnings of our foreign subsidiaries have been taxed in the U.S. under either the one-time tax imposed on the deemed repatriation of undistributed foreign earnings (the “transition tax”), or the global intangible low-taxed income tax regime imposed by the Tax Cuts and Jobs Act of 2017. However, the distribution of earnings by our foreign subsidiaries in the form of dividends, or otherwise, may be subject to additional taxation. We believe that we are able to maintain sufficient liquidity for our domestic operations and commitments without repatriating cash from our foreign subsidiaries. Therefore, we continue to assert that the remaining undistributed earnings of our foreign subsidiaries are indefinitely reinvested.
We finance our operating and investing needs primarily with borrowings under our Revolving Credit Facility and Receivables Facility, as well as uncommitted lines of credit entered into by certain of our foreign subsidiaries to support local operations, some of which are overdraft facilities. The Revolving Credit Facility has a borrowing limit of $1,725 million and the purchase limit under the Receivables Facility is $1,550 million. As of June 30, 2025, we had $475.0 million outstanding on the Revolving Credit Facility and $1,300.0 million outstanding under the Receivables Facility. The maximum borrowing limits of our international lines of credit vary by facility and range between $0.6 million and $9.5 million. Our international lines of credit generally are renewable on an annual basis and certain facilities are fully and unconditionally guaranteed by Wesco Distribution. Accordingly, certain borrowings under these lines directly reduce availability under our Revolving Credit Facility. As of June 30, 2025, we had $5.6 million outstanding under our international lines of credit.
For information regarding amendments to the Receivables Facility and Revolving Credit Facility as well as disclosure of our debt instruments, including our outstanding indebtedness as of June 30, 2025, see Note 9, “Debt” of our Notes to the unaudited Condensed Consolidated Financial Statements.
An analysis of cash flow for the first six months of 2025 and 2024 follows:
Operating Activities
Net cash provided by operating activities for the first six months of 2025 totaled $135.8 million, compared to $522.5 million for the first six months of 2024. Net cash provided by operating activities for the first six months of 2025 included net income of $293.1 million and non-cash adjustments to net income totaling $130.0 million, which primarily comprised depreciation and amortization, stock-based compensation expense, and amortization of debt issuance costs and debt discount.
Other sources of cash in the first six months of 2025 primarily included an increase in accounts payable of $574.7 million primarily due to the increase in inventory, as well as the timing of purchases and payment to suppliers, and an increase in other current and noncurrent liabilities of $21.9 million, primarily due to increases in accrued interest payable and accrued legal expenses. Primary uses of cash in the first six months of 2025 included an increase in trade accounts receivable of $431.2 million due to significant growth in sales in the CSS segment, as well as the timing of receipts from customers, and an increase in inventories of $403.1 million, primarily due to an increase in volume related to ongoing projects and stock replenishment. Uses of cash in the first six months of 2025 also included a decrease in accrued payroll and benefit costs of $38.0 million primarily due to the payment of management incentive compensation earned in 2024 and a decrease in accrued incentives, and an increase in other current and noncurrent assets of $24.4 million primarily due to increases in capitalized costs associated with developing cloud computing arrangements.
Net cash provided by operating activities for the first six months of 2024 included net income of $348.9 million and non-cash adjustments to net income totaling $32.1 million, which primarily comprised depreciation and amortization, a loss on abandonment of assets, stock-based compensation expense, amortization of debt discount and debt issuance costs, a loss recognized on the extinguishment of debt, and pension settlement costs, partially offset by a gain resulting from the divestiture of the WIS business, as described in Note 4, “Acquisitions and Divestitures”.
Other sources of cash in the first six months of 2024 included an increase in accounts payable of $341.9 million primarily due to the timing of inventory purchases and payment to suppliers, an increase in other current and noncurrent liabilities of $69.6 million, due to increases in accrued interest payable, deferred revenue, and federal income taxes payable, and a decrease in other accounts receivable of $60.7 million primarily due to the collection of supplier volume rebates earned in 2023 in excess of income accrued during the current period. Net operating cash flow was also positively impacted by $18.9 million from a decrease in inventories. Primary uses of cash in the first six months of 2024 included an increase in trade accounts receivable of $258.8 million due to the timing of receipts from customers, and an increase in other current and noncurrent assets of $90.0 million primarily due to an increase in supplier prepayments, capitalized costs associated with developing cloud computing arrangements, and an increase in federal income taxes receivable.

Contractual Cash Obligations and Other Commercial Commitments
There were no material changes in our contractual obligations and other commercial commitments that would require an update to the disclosure provided in our Annual Report on Form 10-K for the fiscal year ended December 31, 2024.
Seasonality
Our operating results are not significantly affected by seasonal factors. Sales during the first and fourth quarters have historically been affected by a reduced level of activity due to the impact of weather on projects. Sales typically increase beginning in March, with slight fluctuations per month through October. During periods of economic expansion or contraction, our sales by quarter have varied significantly from this pattern.
Critical Accounting Estimates
There have been no significant changes to the critical accounting estimates disclosed in Part II, Item 7. “Management’s Discussion and Analysis of Financial Condition and Results of Operations” of our Annual Report on Form 10-K for the year ended December 31, 2024.
Recent Accounting Standards

Forward-Looking Statements
All statements made herein that are not historical facts should be considered as “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995. Such statements involve known and unknown risks, uncertainties and other factors that may cause actual results to differ materially. These statements include, but are not limited to, statements regarding business strategy, growth strategy, competitive strengths, productivity and profitability enhancement, competition, new product and service introductions, and liquidity and capital resources. Such statements can generally be identified by the use of words such as “anticipate,” “plan,” “believe,” “estimate,” “intend,” “expect,” “project,” and similar words, phrases or expressions or future or conditional verbs such as “could,” “may,” “should,” “will,” and “would,” although not all forward-looking statements contain such words. These forward-looking statements are based on current expectations and beliefs of Wesco's management, as well as assumptions made by, and information currently available to, Wesco's management, current market trends and market conditions and involve risks and uncertainties, many of which are outside of Wesco's and Wesco's management's control, and which may cause actual results to differ materially from those contained in forward-looking statements. Accordingly, you should not place undue reliance on such statements.
Important factors that could cause actual results or events to differ materially from those presented or implied in the forward-looking statements include, among others, the failure to achieve the anticipated benefits of, and other risks associated with, acquisitions, joint ventures, divestitures and other corporate transactions; the inability to successfully integrate acquired businesses; the impact of increased interest rates or borrowing costs; fluctuations in currency exchange rates; evolving impacts from tariffs or other trade tensions between the U.S. and other countries (including implementation of new tariffs and retaliatory measures); failure to adequately protect Wesco's intellectual property or successfully defend against infringement claims; the inability to successfully deploy new technologies, digital products and information systems or to otherwise adapt to emerging technologies in the marketplace, such as those incorporating artificial intelligence; failure to execute on our efforts and programs related to environmental, social and governance (ESG) matters; unanticipated expenditures or other adverse developments related to compliance with new or stricter government policies, laws or regulations, including those relating to data privacy, sustainability and environmental protection; the inability to successfully develop, manage or implement new technology initiatives or business strategies, including with respect to the expansion of e-commerce capabilities and other digital solutions and digitalization initiatives; disruption of information technology systems or operations; natural disasters (including as a result of climate change), health epidemics, pandemics and other outbreaks; supply chain disruptions; geopolitical issues, including the impact of the evolving conflicts in the Middle East and Russia/Ukraine; the impact of sanctions imposed on, or other actions taken by the U.S. or other countries against, Russia or China; the failure to manage the increased risks and impacts of cyber incidents or data breaches; and exacerbation of key materials shortages, inflationary cost pressures, material cost increases, demand volatility, and logistics and capacity constraints, any of which may have a material adverse effect on the Company's business, results of operations and financial condition. All such factors are difficult to predict and are beyond the Company's control. Additional factors that could cause results to differ materially from those described above can be found in Wesco's most recent Annual Report on Form 10-K and other periodic reports filed with the U.S. Securities and Exchange Commission.
Item 3. Quantitative and Qualitative Disclosures about Market Risks.
For a discussion of changes to the market risks that were previously disclosed in our Annual Report on Form 10-K for the fiscal year ended December 31, 2024, refer to Part I, Item 2, “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and to Part II, Item 1A, “Risk Factors”.
Item 4. Controls and Procedures.
Under the supervision and with the participation of our management, including our principal executive officer and principal financial officer, we conducted an evaluation of our disclosure controls and procedures (as defined in Exchange Act Rules 13a-15(e) and 15d-15(e)) and internal control over financial reporting (as defined in Exchange Act Rules 13a-15(f) and 15d-15(f)). Based on this evaluation, our principal executive officer and our principal financial officer concluded that our disclosure controls and procedures and internal control over financial reporting were effective as of the end of the period covered by this report.
There were no changes in the Company’s internal control over financial reporting that occurred during the quarterly period ended June 30, 2025, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

During the quarterly period ended June 30, 2025, the Company reached certain milestones as it relates to the multi-year, phased development and implementation of a new Digital and Data Platform (“DDP”). The DDP is intended to be a unified, technology-enabled operating model that spans all business functions, maintains and enhances the flow of financial information, and improves resource efficiency. The implementation, in certain cases, may affect the processes that constitute the Company’s internal control over financial reporting and will require testing for effectiveness.
The Company concluded, as part of its evaluation described in the above paragraphs, that the current quarter developments have not materially affected, or are reasonably likely to materially affect, its internal control over financial reporting and will continue to make such an assessment throughout the implementation period.

PART II—OTHER INFORMATION
Item 1. Legal Proceedings.
As set forth in Note 12, “Commitments and Contingencies” to the Notes to the unaudited Condensed Consolidated Financial Statements, from time to time, a number of lawsuits and claims have been or may be asserted against us relating to the conduct of our business, including litigation relating to commercial, product and employment matters. The outcome of any litigation cannot be predicted with certainty, and some lawsuits may be determined adversely to us. However, management does not believe that the ultimate outcome of any such pending matters is likely to have a material adverse effect on our financial condition or liquidity, although the resolution in any fiscal period of one or more of these matters may have a material adverse effect on our results of operations for that period.
Item 1A. Risk Factors.
There have been no material changes to the risk factors previously disclosed in Item 1A. to Part I of WESCO International, Inc.’s Annual Report on Form 10-K for the fiscal year ended December 31, 2024.

Total | 149,262 |  |  | $ | 169.74 |  |  | 147,300 |  |  |

(1) There were 1,962 shares purchased during the quarterly period ended June 30, 2025 that were not part of the publicly announced share repurchase program. These shares were surrendered by stock-based compensation plan participants to satisfy tax withholding obligations arising from the exercise of stock-settled stock appreciation rights and vesting of restricted stock units.
(2) On May 31, 2022, Wesco’s Board of Directors authorized the repurchase of up to $1 billion of the Company’s common stock and Series A Preferred Stock. The share repurchase authorization has no expiration date and may be modified, suspended, or terminated at any time without prior notice. During the three months ended June 30, 2025, the Company entered into spot repurchase transactions through brokers to purchase 147,300 shares of its common stock in the open market for cash totaling $25.0 million. Wesco funded the repurchases with available cash and borrowings under its accounts receivable securitization and revolving credit facilities.
The following table sets forth all issuer purchases of Series A Preferred Stock during the three months ended June 30, 2025:

| Total Number of Shares Purchased |  | Average Price Paid Per Share |  | Total Number of Shares Purchased as Part of Publicly Announced Plans or Programs (1) |  | Approximate Dollar Value of Shares That May Yet be Purchased Under the Plans or Programs (1)
Period |  |  |  |  |  |  | (In millions)

Total | 21,612 |  |  | $ | 25,000.00 |  |  | 21,612 |  |  |

(1) As of June 22, 2025, after receiving prior authorization from Wesco's Board of Directors, separate from the May 31, 2022 share purchase authorization noted above, the Company redeemed all 21,612 outstanding shares of its Series A Preferred Stock, and the related depositary shares, each representing 1/1,000th of one share of Series A Preferred Stock, at a redemption price of $25,000 per share, totaling $540.3 million. This redemption did not impact the approximate dollar value of shares that may be repurchased under the May 31, 2022 program. Wesco funded the redemption with borrowings under its accounts receivable securitization and revolving credit facilities, which had been partially repaid with the net proceeds from the issuance of its 6.375% senior notes due 2033 in the first quarter of 2025 and subsequently redrawn for this redemption.
