PITTSBURGH, Feb. 10, 2026 /PRNewswire/ -- Wesco International (NYSE: WCC), a leading provider of business-to-business distribution, logistics services and supply chain solutions, announces its results for the fourth quarter and full year 2025.

"We closed out 2025 with positive momentum and again outperformed the market with our leading portfolio of products, services and solutions. Record sales of $23.5 billion were up 8% and increased by double-digits in the second half. Backlog was up 19% to a record level at year end, highlighting the strength of our business, and providing another proof point that Wesco is benefiting from the secular growth trends of AI-driven data centers, increased power generation, and supply chain re-shoring," said John Engel, Chairman, President and CEO.

Mr. Engel continued, "In the fourth quarter, CSS and EES delivered excellent results. CSS delivered 16% sales growth while expanding adjusted EBITDA margin 90 basis points and EES delivered 9% sales growth with adjusted EBITDA margin up 50 basis points. UBS continued to face ongoing sales and margin challenges with public power customers, while sales to investor owned utilities accelerated in the fourth quarter. Utility backlog increased over 20% at year end, providing a strong set-up for 2026. Adjusted EPS in the quarter was below our expectations, as the continued operating strength in our CSS and EES businesses was more than offset by lower sales and margin in UBS. Additionally, adjusted EPS was impacted to a larger degree by non-operating items, including updated tax positions."

Mr. Engel continued, "Due to our strong fourth quarter sales, particularly when considering normal seasonality, we increased our investment in working capital which impacted our normal expectation of cash generation in the quarter. We expect to collect cash from our higher receivables balance during the first quarter. We expect much stronger cash generation in 2026 as we continue to make progress on our working capital management initiatives. In the near term, our capital allocation priorities remain focused on debt reduction and stock repurchases to offset annual equity award dilution. We also continue to invest in our tech enabled business transformation and manage an active M&A pipeline."

Mr. Engel added, "We made excellent progress on our enterprise-wide digitalization efforts in 2025. We advanced our technology and capabilities build and have deployed our new technology stack in pilot locations in each of our three business units. The centerpiece of our new tech stack is a world-class data lake where we're working to apply AI to improve the efficiency and effectiveness of our business. We were pleased to be recognized by Fortune in their inaugural AI ranking of Fortune 500 companies with a number 10 ranking. Once our digital transformation is completed, we will accelerate our earnings growth through even greater cross-sell, expand our margins through improved pricing and operating cost leverage, and increase our working capital turns by leveraging our single global IT instance."

Mr. Engel concluded, "Looking ahead in 2026, we expect to continue to outperform the market and deliver mid- to high-single-digit organic sales growth, strong operating leverage and margin expansion, double-digit EPS growth, and improved free cash flow generation. I am pleased to announce that we plan to increase our common stock dividend 10% again this year to $2.00 per share. As the market leader, and with positive momentum building, I'm confident that Wesco will continue to outperform our markets and deliver exceptional value to our customers and shareholders in 2026 and beyond. Finally, I continue to be very proud of our talented and dedicated Wesco team, whose relentless focus on serving customers, advancing our digital transformation agenda, and driving superior execution across our businesses is producing notable results, as we realize our vision of becoming the best tech-enabled supply chain solutions provider in the world."

Net Sales

  • On an organic basis, which removes the impact of the Ascent, LLC ("Ascent") acquisition and differences in foreign exchange rates, sales for the fourth quarter of 2025 grew by 9.2%. The increase in organic sales reflects volume growth in all three segments (CSS, EES and UBS), as well as a favorable impact from changes in price. Backlog at the end of the fourth quarter of 2025 increased by 19% compared to the end of the fourth quarter of 2024.
  • For 2025, organic sales, which removes the impact of the Wesco Integrated Supply ("WIS") divestiture and Ascent acquisition, differences in foreign exchange rates, and the impact from the number of workdays, grew by 8.6%. The increase in organic sales reflects volume growth in the CSS and EES segments, as well as a favorable impact from changes in price.

Gross Profit and Gross Margin

  • Gross margin for the fourth quarter of 2025 remained flat compared to the fourth quarter of 2024.
  • The decrease in gross margin for the twelve months ended December 31, 2025 primarily reflects a decrease in gross margin across all three segments, most significantly in the UBS segment due to competitive pressures in the public power market, as well as in the EES and CSS segments driven by large project sales.

Selling, General, and Administrative ("SG&A") Expenses

  • The increase in SG&A expenses for the fourth quarter of 2025 is driven by higher commissions and incentives, higher salaries, higher IT costs, higher transportation costs, and increased costs to operate our facilities. SG&A expenses for the fourth quarter of 2025 include $11.0 million of digital transformation costs, compared to $10.0 million of digital transformation and restructuring costs for the fourth quarter of 2024. Adjusted for these costs, SG&A expenses were 14.8% and 14.7% of net sales for the fourth quarter of 2025 and 2024, respectively.
  • The increase in SG&A expenses for 2025 is driven by higher salaries, higher commissions and incentives, increased costs to operate our facilities, higher transportation costs, and higher IT costs, partially offset by the impact of the divestiture of the WIS business. SG&A expenses for 2025 include $35.2 million of digital transformation costs. SG&A expenses for 2024 include $37.0 million of digital transformation and restructuring costs, a $17.8 million loss on abandonment of assets and $4.9 million of excise taxes on excess pension plan assets. Adjusted for these costs, SG&A expenses were 14.9% of net sales for 2025 and 2024.

Adjusted EBITDA and Adjusted EBITDA Margin

  • The increase in Adjusted EBITDA for the fourth quarter of 2025 primarily reflects an increase in net sales, partially offset by increases in cost of goods sold, related to large project sales with lower margins, and SG&A expenses as described above.
  • The increase in Adjusted EBITDA for 2025 primarily reflects an increase in net sales, partially offset by increases in cost of goods sold, related to large project sales with lower margins, and SG&A expenses as described above.

Effective Tax Rate

  • The provision for income taxes was $57.6 million for the fourth quarter of 2025 compared to $43.5 million for the fourth quarter of 2024, resulting in effective tax rates of 26.4% and 20.8%, respectively. The effective tax rate for the quarter ended December 31, 2025 was higher due to higher tax expense related to uncertain tax positions and an increase in valuation allowance against foreign tax credit deferred tax assets.
  • The provision for income taxes was $213.4 million for 2025 compared to $231.6 million for the 2024, resulting in effective tax rates of 24.9% and 24.4%, respectively.

Adjusted Earnings Per Diluted Share

  • The increase in adjusted earnings per diluted share in the fourth quarter of 2025 primarily reflects the favorable impact of the June 2025 redemption of the Company's 10.625% Series A Fixed-Rate Reset Cumulative Perpetual Preferred Stock (the "Series A Preferred Stock") and the corresponding decrease in preferred dividends, as well as higher adjusted EBITDA. The increase in adjusted earnings per diluted share was offset by a $23.5 million increase in interest expense primarily driven by the issuance of the 2033 Notes and an increase from adjustments for uncertain tax positions, partially offset by lower borrowings and lower interest rates on the Receivables Facility. There was also a positive impact from the reduction in outstanding common shares during the fourth quarter of 2025 as compared to the fourth quarter of 2024.
  • The increase in adjusted earnings per diluted share in 2025 primarily reflects the favorable impact of the Series A Preferred Stock redemption and the corresponding decrease in preferred dividends. There was also a positive impact from the reduction in outstanding common shares during 2025 as compared to 2024.

Operating Cash Flow

  • Net cash provided by operating activities for the fourth quarter of 2025 totaled $71.9 million compared to $276.6 million in the fourth quarter of 2024. The $204.7 million decrease is primarily driven by a $201.9 million impact from changes in accounts payable, due to the timing of payments to suppliers, as well as a $21.6 million impact from changes in trade accounts receivable, driven primarily by sales growth in all three segments.
  • Net cash provided by operating activities for 2025 totaled $125.0 million, compared to $1,101.2 million for 2024. The $976.2 million decrease is primarily driven a $507.3 million impact from changes in trade accounts receivable and a $428.1 million impact from changes in inventories. The impact from trade accounts receivable was primarily due to sales growth in the CSS and EES segments, as well as the timing of receipts from customers as compared to the prior year. The impact from inventories was primarily due to an increase in volume related to growth in large projects as compared to the prior year. These decreases were partially offset by an increase in net income as adjusted for certain non-cash items.

NON-GAAP FINANCIAL MEASURES

In addition to the results provided in accordance with U.S. Generally Accepted Accounting Principles ("U.S. GAAP") above, this earnings release includes certain non-GAAP financial measures. These financial measures include organic sales growth, gross profit, gross margin, earnings before interest, taxes, depreciation and amortization (EBITDA), adjusted EBITDA, adjusted EBITDA margin, financial leverage, free cash flow, adjusted selling, general and administrative expenses, adjusted income from operations, adjusted operating margin, 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. The Company believes that these non-GAAP measures are useful to investors 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 such as digital transformation costs, restructuring costs, cloud computing arrangement amortization, pension settlement cost and excise taxes on excess pension plan assets related to the settlement of the Anixter Inc. Pension Plan, loss on abandonment of assets, the gain recognized on the divestiture of the WIS business, the loss on termination of business arrangement, and the related income tax effects, as well as the gain on the redemption of the Series A Preferred Stock, allowing investors to more easily compare the Company's financial performance from period to period. Management does not use these non-GAAP financial measures for any purpose other than the reasons stated above.

          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 fourth quarter of 2025 had the same
number of workdays as the fourth quarter of 2024, and 2025 had one less workday compared to 2024.

            (1)   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.
      As a result, the reportable segment financial information for the three months ended December 31, 2024 has been recast to conform to the current year presentation.
      The recast does not impact previously reported condensed consolidated results.



          
            (2)  The reportable segments do not incur income taxes and interest expense as these costs are centrally controlled through the Corporate tax and treasury functions.



          
            (3)  Digital transformation costs include costs associated with certain digital transformation initiatives.



          
            (4)  Cloud computing arrangement amortization consists of expense recognized in selling, general and administrative expenses for capitalized implementation costs
      for cloud computing arrangements to support our digital transformation initiatives.



          
            (5)  Restructuring costs include severance costs incurred pursuant to an ongoing restructuring plan.



          
            (6)  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.





          Note: EBITDA, Adjusted EBITDA and Adjusted EBITDA margin % are non-GAAP financial measures that provide indicators of the Company's performance and its ability

            (1)   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. As a
      result, the reportable segment financial information for the year ended December 31, 2024 has been recast to conform to the current year presentation. The
      recast does not impact previously reported condensed consolidated results.



          
            (2)  The reportable segments do not incur income taxes and interest expense as these costs are centrally controlled through the Corporate tax and treasury
      functions.



          
            (3)    Other income for the UBS segment includes the gain on the divestiture of the WIS business.



          
            (4)  Digital transformation costs include costs associated with certain digital transformation initiatives.



          
            (5)  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 operation.



          
            (6)  Cloud computing arrangement amortization consists of expense recognized in selling, general and administrative expenses for capitalized implementation
      costs for cloud computing arrangements to support our digital transformation initiatives.



          
            (7)  Restructuring costs include severance costs incurred pursuant to an ongoing restructuring plan.



          
            (8)  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.





          Note: EBITDA, Adjusted EBITDA and Adjusted EBITDA margin % are non-GAAP financial measures that provide indicators of the Company's performance
and its ability to meet debt service requirements. For the year ended December 31, 2025, Adjusted EBITDA is defined as earnings before interest, taxes,
depreciation and amortization before other non-operating expenses (income), non-cash stock-based compensation expense, digital transformation costs,
cloud computing arrangement amortization and restructuring costs. For the year ended December 31, 2024, Adjusted EBITDA is defined as earnings before
interest, taxes, depreciation and amortization before other non-operating expenses (income), non-cash stock-based compensation expense, digital
transformation costs, loss on abandonment of assets, cloud computing arrangement amortization, restructuring costs and excise taxes on excess pension
plan assets related to the final settlement of the Anixter Inc. Pension Plan. Adjusted EBITDA margin % is calculated by dividing Adjusted EBITDA by net sales.

 Note: Financial leverage is a non-GAAP measure of the use of debt. Financial leverage ratio is calculated by dividing total debt, excluding debt discount, debt issuance costs and fair value adjustments, net of cash, by adjusted EBITDA. EBITDA is defined as the trailing twelve months earnings before interest, taxes, depreciation and amortization. Adjusted EBITDA is defined
  as the trailing twelve months EBITDA before other non-operating expense (income), non-cash stock-based compensation expense, digital transformation costs, cloud computing arrangement amortization, restructuring costs, loss on abandonment of assets, and excise taxes on excess pension plan assets related to the final settlement of the Anixter Inc. Pension Plan.

 Note: Free cash flow is a non-GAAP financial measure of liquidity. Capital expenditures are deducted from operating cash flow to determine free cash flow. Free cash flow is available to fund investing and financing activities. For the three and twelve months ended December 31, 2025 and 2024, the Company paid for certain costs related to digital transformation and
  restructuring. Such expenditures have been added back to operating cash flow to determine free cash flow for such periods. Our calculation of free cash flow may not be comparable to similar measures used by other companies.
