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 2022.

“Wesco delivered a stellar encore performance for the full year 2022 including exceptional fourth quarter results, clearly demonstrating our ability to drive sustained growth and market outperformance. The success of our business model and integration efforts over the past two and a half years since our transformational combination with Anixter resulted in record full year sales of $21.4 billion, an increase of 18% over last year. We again set new company records for margin and profitability, and reduced leverage to below 3.0x for the first time since 2019. With this trajectory, we have taken a significant step forward in the achievement of our long-term target of 10%+ EBITDA margin. I am confident 2023 will be another transformational year with additional advances in our digital capabilities, strong topline growth, continued margin expansion and record free cash generation to support our capital allocation priorities,” said John Engel, Chairman, President and CEO.

Mr. Engel continued, “Strong seasonal fourth-quarter growth was driven by secular demand trends, continued share gains and the start of supply chain pressures easing. We meaningfully reduced net working capital while delivering stronger than anticipated topline growth in the fourth quarter, and generated record quarterly free cash flow of approximately $400 million.”

Mr. Engel added, “Each of our strategic business units again delivered strong double-digit organic sales and profit growth underscoring the success of our enterprise-wide cross selling and margin improvement programs. The fourth-quarter performance of our latest acquisition, Rahi Systems, builds on our data center solutions strategy and better positions us to capture value from this important secular-growth market. Our profitable execution across all three business units supports our investment in Wesco’s digital transformation positioning us to deliver an even higher level of performance, operating efficiency and customer loyalty.”

Mr. Engel concluded, “We are building on our strong positive momentum and 2023 is off to an excellent start. Our three-year post-merger integration plan is coming to a close. Our digital transformation plan is accelerating, and we are on-track to deliver advanced digital capabilities that will create superior value for our customers and supplier partners. We are confident in our ability to drive mid- to high-single digit sales growth this year, along with continued EBITDA margin expansion and approximately $600 to $800 million in free cash flow generation that supports our growth initiatives and capital allocation priorities. Most importantly, our dedicated team of colleagues continues to provide resilient and critical supply chain solutions for our customers around the world, capturing the benefits of our exposure to sustainable secular trends that are deep and drive our future sales and profitability. We look forward with greater confidence than ever to a future of sustained growth and market outperformance.”

The following are results for the three months ended December 31, 2022 compared to the three months ended December 31, 2021:

• Net sales were $5.6 billion for the fourth quarter of 2022 compared to $4.9 billion for the fourth quarter of 2021, an increase of 14.6%, reflecting price inflation and volume growth, secular demand trends, execution of our cross-sell program, and moderate easing of supply chain constraints. Organic sales for the fourth quarter of 2022 grew 14.4% as the acquisition of Rahi Systems on November 1, 2022 positively impacted reported net sales by 2.3%, while fluctuations in foreign exchange rates negatively impacted reported net sales by 2.1%. Sequentially, net sales grew 2.1% while organic sales increased 3.7%. The acquisition of Rahi Systems positively impacted reported net sales by 2.1%, while the number of workdays and fluctuations in foreign exchange rate changes negatively impacted reported net sales by 3.1% and 0.6%, respectively. Backlog at the end of the fourth quarter of 2022 increased by more than 40% compared to the end of 2021. Sequentially, backlog declined slightly by approximately 1% following seven consecutive quarters of strong growth.

• Cost of goods sold for the fourth quarter of 2022 was $4.3 billion compared to $3.8 billion for the fourth quarter of 2021, and gross profit was $1.2 billion and $1.0 billion, respectively. As a percentage of net sales, gross profit was 21.9% and 20.8% for the fourth quarter of 2022 and 2021, respectively. Gross profit as a percentage of net sales for the fourth quarter of 2022 reflects our focus on value-driven pricing and pass-through of inflationary costs, along with the continued momentum of our gross margin improvement program and higher supplier volume rebates as a percentage of net sales. Cost of goods sold for the fourth quarter of 2021 included a write-down to the carrying value of certain personal protective equipment inventories that unfavorably impacted gross profit as a percentage of net sales by approximately 12 basis points.

• Selling, general and administrative (“SG&A”) expenses were $793.1 million, or 14.3% of net sales, for the fourth quarter of 2022 compared to $733.7 million, or 15.1% of net sales, for the fourth quarter of 2021. SG&A expenses for the fourth quarter of 2022 and 2021 include merger-related and integration costs of $15.2 million and $38.7 million, respectively. Adjusted for these amounts, SG&A expenses were $777.9 million, or 14.0% of net sales, for the fourth quarter of 2022 and $695.0 million, or 14.3% of net sales, for the fourth quarter of 2021. Adjusted SG&A expenses for the fourth quarter of 2022 reflect higher salaries due to wage inflation and increased headcount, an increase in commissions and volume-related costs driven by significant sales growth, as well as the impact of the Rahi Systems acquisition. In addition, digital transformation initiatives contributed to higher expenses in the fourth quarter of 2022, including those related to professional and consulting fees. These increases were partially offset by the realization of integration cost synergies and a reduction to incentive compensation expense.

• Depreciation and amortization for the fourth quarter of 2022 was $43.4 million compared to $53.9 million for the fourth quarter of 2021, a decrease of $10.5 million. In connection with an integration initiative to review the Company's brand strategy, certain legacy trademarks are migrating to a master brand architecture, which resulted in $0.4 million and $11.8 million of accelerated amortization expense for the fourth quarter of 2022 and 2021, respectively.

• Operating profit was $381.8 million for the fourth quarter of 2022 compared to $220.3 million for the fourth quarter of 2021, an increase of $161.5 million, or 73.3%. Operating profit as a percentage of net sales was 6.9% for the current quarter, compared to 4.5% for the fourth quarter of the prior year. Adjusted for the merger-related and integration costs, and accelerated trademark amortization described above, operating profit was $397.4 million, or 7.1% of net sales, for the fourth quarter of 2022 and $270.8 million, or 5.6% of net sales, for the fourth quarter of 2021. Adjusted operating margin was up 150 basis points compared to the prior year.

• Net interest expense for the fourth quarter of 2022 was $87.3 million compared to $60.4 million for the fourth quarter of 2021. The increase reflects higher borrowings and an increase in variable interest rates.

• The effective tax rate for the fourth quarter of 2022 was 24.6% compared to 15.7% for the fourth quarter of 2021. The effective tax rate for the fourth quarter of the prior year was favorably impacted by a reduction in the valuation allowance recorded against certain foreign tax credit carryforwards, as well as higher tax benefits related to intercompany financing and certain foreign derived intangible income.

• Net income attributable to common stockholders was $204.6 million for the fourth quarter of 2022 compared to $153.1 million for the fourth quarter of 2021. Adjusted for merger-related and integration costs, accelerated trademark amortization expense, and the related income tax effects, net income attributable to common stockholders was $216.3 million for the fourth quarter of 2022. Adjusted for merger-related and integration costs, accelerated trademark amortization expense, a $36.6 million curtailment gain resulting from the remeasurement of the Company's pension obligations in the U.S. and Canada due to amending certain terms of such defined benefit plans, and the related income tax effects, net income attributable to common stockholders was $165.7 million for the fourth quarter of 2021. Adjusted net income attributable to common stockholders increased 30.5% year-over-year.

• Earnings per diluted share for the fourth quarter of 2022 was $3.90, based on 52.4 million diluted shares, compared to $2.93 for the fourth quarter of 2021, based on 52.3 million diluted shares. Adjusted for merger-related and integration costs, accelerated trademark amortization expense, and the related income tax effects, earnings per diluted share for the fourth quarter of 2022 was $4.13. Adjusted for merger-related and integration costs, accelerated trademark amortization expense, curtailment gain, and the related income tax effects, earnings per diluted share for the fourth quarter of 2021 was $3.17. Adjusted earnings per diluted share increased 30.3% year-over-year, including a positive impact from the Rahi acquisition completed during the quarter.

• Operating cash flow for the fourth quarter of 2022 was an inflow of $421.7 million compared to an outflow of $105.5 million for the fourth quarter of 2021. Free cash flow for the fourth quarter of 2022 was $398.7 million, or 172.7% of adjusted net income, reflecting a significant reduction in working capital including a decrease in inventories of $69.3 million from the end of the third quarter of 2022. An increase in accounts payable of $73.3 million and a decrease in trade accounts receivable of $47.1 million also contributed to the strong free cash flow performance for the fourth quarter of 2022. Additionally, the Company repurchased $11.1 million of its common stock shares during the fourth quarter of 2022.

The following are results for the year ended December 31, 2022 compared to the year ended December 31, 2021:

• Net sales were $21.4 billion for 2022 compared to $18.2 billion for 2021, an increase of 17.6% reflecting price inflation and volume growth, secular demand trends, and execution of our cross-sell program. Organic sales for 2022 grew 18.2% as the acquisition of Rahi Systems in the fourth quarter of 2022, offset by the divestiture of Wesco's legacy utility and data communications businesses in Canada in the first quarter of 2021, positively impacted reported net sales by 0.5%. Additionally, the number of workdays positively impacted reported net sales by 0.4%, while fluctuations in foreign exchange rates negatively impacted reported net sales by 1.5%.

• Cost of goods sold for 2022 was $16.8 billion compared to $14.4 billion for 2021, and gross profit was $4.7 billion and $3.8 billion, respectively. As a percentage of net sales, gross profit was 21.8% and 20.8% for 2022 and 2021, respectively. Gross profit as a percentage of net sales for 2022 reflects our focus on value-driven pricing and pass-through of inflationary costs, along with the continued momentum of our gross margin improvement program and higher supplier volume rebates as a percentage of net sales. Cost of goods sold for 2021 included a write-down to the carrying value of certain personal protective equipment inventories that unfavorably impacted gross profit as a percentage of net sales by approximately 14 basis points.

• SG&A expenses for 2022 were $3.0 billion, or 14.2% of net sales, compared to $2.8 billion for 2021, or 15.3% of net sales. SG&A expenses for 2022 include merger-related and integration costs of $67.4 million. Adjusted for this amount, SG&A expenses for 2022 were 13.9% of net sales and reflect higher salaries due to wage inflation and increased headcount, as well as an increase in commissions and volume-related costs driven by significant sales growth. In addition, digital transformation initiatives contributed to higher expenses in 2022, including those related to professional and consulting fees. These increases were partially offset by the realization of integration cost synergies and a reduction to incentive compensation expense. SG&A expenses for 2021 include merger-related and integration costs of $158.5 million, as well as a net gain of $8.9 million resulting from the Canadian divestitures described above. Adjusted for these amounts, SG&A expenses were 14.5% of net sales for 2021.

• Depreciation and amortization for 2022 was $179.0 million compared to $198.6 million for 2021, a decrease of $19.6 million. In connection with an integration initiative to review the Company's brand strategy, certain legacy trademarks are migrating to a master brand architecture, which resulted in $9.8 million and $32.0 million of accelerated amortization expense for 2022 and 2021, respectively.

• Operating profit was $1.4 billion for 2022 compared to $0.8 billion for 2021, an increase of $636.2 million, or 79.3%. Operating profit as a percentage of net sales was 6.7% for the current year, compared to 4.4% for the prior year. Operating profit for 2022 includes the merger-related and integration costs, and accelerated trademark amortization expense described above. Adjusted for these amounts, operating profit was 7.1% of net sales. For 2021, operating profit was 5.4% as adjusted for merger-related and integration costs of $158.5 million, accelerated trademark amortization expense of $32.0 million, and the net gain on the Canadian divestitures of $8.9 million. Adjusted operating margin was up 170 basis points compared to the prior year.

• Net interest expense for 2022 was $294.4 million compared to $268.1 million for 2021. The increase reflects higher borrowings and an increase in variable interest rates.

• The effective tax rate for 2022 was 24.2% compared to 19.9% for 2021. The effective tax rates for both the current year and the prior year were favorably impacted by the tax benefits related to intercompany financing and reductions in the valuation allowance recorded against certain foreign tax credit carryforwards. The higher effective tax rate in the current year is primarily due to lower tax benefits from intercompany financing arrangements resulting from changes in Canadian tax law and certain foreign derived intangible income.

• Net income attributable to common stockholders was $803.1 million for 2022 compared to $408.0 million for 2021. Adjusted for merger-related and integration costs, accelerated trademark amortization expense, and the related income tax effects, net income attributable to common stockholders was $860.1 million for 2022. Adjusted for merger-related and integration costs, accelerated trademark amortization expense, net gain on Canadian divestitures, a $36.6 million curtailment gain, and the related income tax effects, net income attributable to common stockholders was $519.3 million for 2021. Adjusted net income attributable to common stockholders increased 65.6% year-over-year.

• Earnings per diluted share for 2022 was $15.33, based on 52.4 million diluted shares, compared to $7.84 for 2021, based on 52.0 million diluted shares. Adjusted for merger-related and integration costs, accelerated trademark amortization expense, and the related income tax effects, earnings per diluted share for 2022 was $16.42. Adjusted for merger-related and integration costs, accelerated trademark amortization expense, net gain on divestitures, curtailment gain, and the related income tax effects, earnings per diluted share for 2021 was $9.98. Adjusted earnings per diluted share increased 64.5% year-over-year.

• Operating cash flow for 2022 was $11.0 million compared to $67.1 million for 2021. Operating cash flow for the current year was lower than the prior year primarily due to changes in working capital, including an increase in inventories of $817.0 million and an increase in trade accounts receivable of $690.6 million. The increase in inventories resulted from investments to address supply chain challenges and to support growth in our sales backlog, including project-based business. The increase in trade accounts receivable was due to significant sales growth. These outflows were partially offset by an increase in accounts payable of $552.9 million.

The year-over-year increase in organic sales reflects price inflation, growth in our industrial, construction, and original equipment manufacturer businesses, as well as the benefits of cross selling and secular growth trends. Additionally, supply chain constraints have had a negative impact on sales in both 2022 and 2021, however, these pressures have begun to moderate.

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 merger-related and integration costs, and the related income tax effect of such items, 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.
