PITTSBURGH, November 4, 2021 /Business Wire/ -- WESCO International, Inc. (NYSE: WCC), a leading provider of business-to-business distribution, logistics services, and supply chain solutions, announces its results for the third quarter of 2021.
“We had another exceptional quarter and again delivered outstanding results across the board. Early in the second year of our transformational combination of WESCO and Anixter, the substantial value creation of the new WESCO is building,” said John Engel, Chairman, President and CEO. “Our sales growth accelerated versus 2019 pre-pandemic levels, and our margin performance and backlog achieved new records for the company. We are outperforming the market across our three business units by utilizing our increased scale, expanded portfolio and industry-leading positions. And, we are continuing to de-lever our balance sheet at a rapid rate while investing in our digital transformation. The impressive progress we’re making in the integration is a direct result of the dedication, commitment and relentless execution of the entire WESCO team. I want to thank all our associates for their strong teamwork on our transformation, supplier engagement and customer focus in providing the products, services and resilient supply chain solutions our customers need.”
Mr. Engel continued, “We are seeing sales and margin momentum in each of our three strategic business units. Based on our strong third quarter results, we are raising our full year 2021 outlook for sales, margin and profitability for the third time this year. We now expect sales to increase 11% to 13%, adjusted EBITDA margin to expand to between 6.4% and 6.5%, and adjusted EPS to grow to a range of $9.20 to $9.40. As a result of our expected sales growth and increasing inventories to support our customers, we are also adjusting our full year 2021 outlook for free cash flow to approximately 80% of net income.”
Mr. Engel added, “We are transforming into a growth company as a result of our digital investments, cross-selling our expanded portfolio of products and services, and providing resilient and sustainable supply chain solutions for our customers around the world. Continued execution of our aggressive integration plan, and capitalizing on the secular growth trends, will only accelerate this shift. The value creation potential of the new WESCO is building, and we are only in the early days.”

The following are results for the three months ended September 30, 2021 compared to the three months ended September 30, 2020.
•Net sales were $4.7 billion for the third quarter of 2021 compared to $4.1 billion for the third quarter of 2020, an increase of 14.2%. Organic sales for the third quarter of 2021 grew by 13.6% as foreign exchange rates positively impacted reported net sales by 1.4% and divestitures negatively impacted reported net sales by 0.8%. Sequentially, net sales grew 2.9% and organic sales increased 3.4%. All segments increased sales versus the prior year period. Backlog at the end of the third quarter of 2021 increased by over 60% compared to the prior year quarter and the end of 2020. Sequentially, backlog grew approximately 15%. WESCO's book-to-bill ratio was above 1.0 for the quarter ended September 30, 2021, indicating strong demand.
•Cost of goods sold for the third quarter of 2021 was $3.7 billion compared to $3.4 billion for the third quarter of 2020, and gross profit was $1.0 billion and $785.5 million, respectively. As a percentage of net sales, gross profit was 21.3% and 19.0% for the third quarter of 2021 and 2020, respectively. Gross profit as a percentage of net sales for the third quarter of 2021 reflects the favorable impact of margin improvement initiatives, partially offset by a write-down to the carrying value of certain personal protective equipment products, which had a negative impact of 10 basis points. Gross profit as a percentage of net sales for the third quarter of 2020 was 19.6% excluding the effect of merger-related fair value adjustments of $28.0 million. Sequentially, gross profit as a percentage of net sales increased 30 basis points from 21.0% for the second quarter of 2021.
•Selling, general and administrative expenses were $721.8 million, or 15.3% of net sales, for the third quarter of 2021, compared to $562.0 million, or 13.6% of net sales, for the third quarter of 2020. SG&A expenses for the third quarter of 2021 include merger-related costs of $35.8 million. Adjusted for this amount, SG&A expenses were $686.0 million, or 14.5% of net sales, for the third quarter of 2021. SG&A expenses for the third quarter of 2021 reflect higher salaries, variable compensation expense and benefit costs, as well as volume-related costs driven by significant sales growth, partially offset by the realization of integration cost synergies. SG&A expenses for the third quarter of 2020 include $14.2 million of merger-related costs, as well as a gain on the sale of an operating branch in the U.S. of $19.8 million. Adjusted for these amounts, SG&A expenses were $567.6 million, or 13.7% of net sales, for the third quarter of 2020, reflecting cost reduction actions taken in response to the COVID-19 pandemic that lowered SG&A expenses as a percentage of net sales by approximately 70 basis points.
•Operating profit was $229.5 million for the third quarter of 2021, compared to $178.1 million for the third quarter of 2020, an increase of $51.4 million, or 28.8%. Operating profit as a percentage of net sales was 4.9% for the current quarter, compared to 4.3% for the third quarter of the prior year. Operating profit for the third quarter of 2021 includes the aforementioned merger-related costs. Additionally, in connection with an integration initiative to review the Company's brand strategy, certain legacy WESCO trademarks are migrating to a master brand architecture, which resulted in $15.1 million of accelerated amortization expense for the third quarter of 2021. Adjusted for these amounts, operating profit was $280.4 million, or 5.9% of net sales. In the third quarter of 2020, operating profit was $200.5 million, or 4.8% of net sales, adjusted for merger-related costs and fair value adjustments totaling $42.2 million and the gain on sale of a U.S. operating branch of $19.8 million. Adjusted operating margin was up 110 basis points compared to the prior year.
•Net interest expense for the third quarter of 2021 was $69.7 million, compared to $74.5 million for the third quarter of 2020. The decrease reflects a reduction of debt, including the repayment of higher fixed rate debt with lower variable rate debt.
•The effective tax rate for the third quarter of 2021 was 27.2%, compared to 23.3% for the third quarter of 2020. The higher effective tax rate in the current quarter reflects the impact on the estimated annual effective tax rate of a decrease in expected foreign tax credit utilization.
•Net income attributable to common stockholders was $105.2 million for the third quarter of 2021, compared to $66.2 million for the third quarter of 2020. Adjusted for merger-related costs and fair value adjustments, accelerated amortization expense associated with migrating to the Company's master brand architecture, gain on sale of a U.S. operating branch, and the related income tax effects, net income attributable to common stockholders was $142.6 million and $83.6 million for the third quarter of 2021 and 2020, respectively, an increase of 70.6%.
•Earnings per diluted share for the third quarter of 2021 was $2.02, based on 52.1 million diluted shares, compared to $1.31 for the third quarter of 2020, based on 50.5 million diluted shares. Adjusted for merger-related costs and fair value adjustments, accelerated amortization expense associated with migrating to the Company's master brand architecture, gain on sale of a U.S. operating branch, and the related income tax effects, earnings per diluted share for the third quarter of 2021 and 2020 was $2.74 and $1.66, respectively, an increase of 65.1%.
•Operating cash flow for the third quarter of 2021 was $69.9 million, compared to $286.3 million for the third quarter of 2020. Free cash flow for the third quarter of 2021 was $85.0 million, or 54% of adjusted net income, compared to $307.4 million, or 315% of adjusted net income, for the third quarter of 2020. Free cash flow for the current year period was lower than the comparable prior year period primarily due to changes in working capital to support double-digit sales growth.

The following are results for the nine months ended September 30, 2021 compared to the nine months ended September 30, 2020. The Company completed the merger with Anixter on June 22, 2020, thereby impacting comparisons to the prior year.

•Cost of goods sold for the first nine months of 2021 was $10.6 billion compared to $6.6 billion for the first nine months of 2020, and gross profit was $2.8 billion and $1.6 billion, respectively. As a percentage of net sales, gross profit was 20.8% and 19.0% for the first nine months of 2021 and 2020, respectively. Gross profit as a percentage of net sales for the first nine months of 2021 reflects the favorable impact of margin improvement initiatives, partially offset by the write-down to the carrying value of certain personal protective equipment products, which had a negative impact of 20 basis points. Gross profit as a percentage of net sales for the first nine months of 2020 was 19.3% excluding the effect of merger-related fair value adjustments of $28.0 million.
•Selling, general and administrative expenses were $2.1 billion, or 15.4% of net sales, for the first nine months of 2021, compared to $1.2 billion, or 14.9% of net sales, for the first nine months of 2020. SG&A expenses for the first nine months of 2021 include merger-related costs of $119.8 million, as well as a net gain of $8.9 million resulting from the sale of WESCO's legacy utility and data communications businesses in Canada during the first quarter of 2021, which were divested in connection with the merger.

Adjusted operating margin was up 100 basis points compared to the prior year.
•Net interest expense for the first nine months of 2021 was $207.7 million, compared to $152.3 million for the first nine months of 2020. The increase in interest expense was driven by financing activity related to the Anixter merger.
•The effective tax rate for the first nine months of 2021 was 22.0%, compared to 22.9% for the first nine months of 2020. The effective tax rate for the current year-to-date period reflects discrete income tax benefits resulting from a decrease in the valuation allowance recorded against foreign tax credit carryforwards of $8.3 million and deductible stock-based compensation of $7.8 million, which were partially offset by discrete income tax expense of $4.2 million associated with return-to-provision adjustments. These discrete items reduced the estimated annual effective tax rate by approximately 3.1 percentage points.

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, adjusted gross profit, gross margin, adjusted gross margin, earnings before interest, taxes, depreciation and amortization (EBITDA), adjusted EBITDA, adjusted EBITDA margin, financial leverage, free cash flow, adjusted income from operations, adjusted operating margin, 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 sales performance, and the use of debt and liquidity on a comparable basis. Additionally, certain non-GAAP measures either focus on or exclude items impacting comparability of results such as merger-related 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.
