PITTSBURGH, February 1, 2018 /PRNewswire/ -- WESCO International, Inc. (NYSE: WCC), a leading provider of electrical, industrial, and communications MRO and OEM products, construction materials, and advanced supply chain management and logistics services, announces its results for the fourth quarter and full year 2017.
Mr. John J. Engel, WESCO's Chairman, President and CEO, commented, "Our fourth quarter results reflect continued positive and broad-based momentum in our business. Sales grew 10% organically, our highest growth rate in six years, with all end markets and geographies contributing. Building on our return to growth in June, our sales momentum accelerated in July and remained consistently high throughout the second half of the year and into January. Backlog grew sequentially versus the typical seasonal decline, and expanded to an all-time record level within the quarter. Operating margin was consistent with our outlook, while free cash flow generation was below expectations due to increased working capital to support our accelerating sales growth."
The following are results for the three months ended December 31, 2017 compared to the three months ended December 31, 2016:

• | Net sales were $2.0 billion for the fourth quarter of 2017, compared to $1.79 billion for the fourth quarter of 2016, an in crease of 11.3%. Organic sales for the fourth quarter of 2017 grew by 10.1% as foreign exchange rates had a 1.2% positive impact on net sales. Sequentially, net sales decreased 0.2% and organic sales increased 1.6%.

• | Cost of goods sold for the fourth quarter of 2017 was $1.61 billion and gross profit was $383.1 million, compared to cost of goods sold and gross profit of $1.44 billion and $348.6 million for the fourth quarter of 2016, respectively. As a percentage of net sales, gross profit was 19.2% and 19.4% for the fourth quarter of 2017 and 2016, respectively.

• | Selling, general and administrative expenses were $285.4 million, or 14.3% of net sales, for the fourth quarter of 2017, compared to $249.9 million, or 13.9% of net sales, for the fourth quarter of 2016.

• | Operating profit was $81.4 million for the current quarter, compared to $82.1 million for the fourth quarter of 2016. Operating profit as a percentage of net sales was 4.1% for the fourth quarter of 2017, compared to 4.6% for the fourth quarter of 2016.

• | The effective tax rate for the current quarter was 65.2%, compared to 26.0% for the prior year fourth quarter. As adjusted, the effective tax rate for the fourth quarter of 2017 was 23.9%. The higher effective tax rate in the current quarter as compared to the effective tax rate for the prior year’s comparable quarter is due to $26.4 million of provisional discrete income tax expense related to the application of the Tax Cuts and Jobs Act of 2017 (TCJA).

• | Net income attributable to WESCO International, Inc. was $22.5 million for the fourth quarter of 2017, compared to a net income of $47.4 million for the fourth quarter of 2016. Adjusted net income attributable to WESCO International, Inc. was $48.9 million for the fourth quarter of December 31, 2017.

• | Earnings per diluted share was $0.47 for the fourth quarter of 2017, based on 47.5 million diluted shares, compared to earnings per diluted share of $0.96 for the fourth quarter of 2016, based on 49.2 million shares. Adjusted earnings per diluted share for the fourth quarter of 2017 was $1.03.

• | Operating cash flow for the fourth quarter of 2017 was $68.0 million, compared to $83.0 million for the fourth quarter of 2016. The reduction in operating cash flow was primarily driven by changes in working capital to support sales growth. Free cash flow for the fourth quarter of 2017 was $62.5 million, or 129% of adjusted net income, compared to $78.2 million, or 164% of adjusted net income, for the fourth quarter of 2016.

The following are results for the year ended December 31, 2017 compared to the year ended December 31, 2016:

• | Net sales were $7.68 billion for 2017, compared to $7.34 billion for 2016, an in crease of 4.7%. Organic sales for 2017 grew by 4.5% as foreign exchange rates and acquisitions had a positive impact on net sales of 0.4% and 0.2%, respectively, and were partially offset by a 0.4% impact from the number of workdays.

• | Cost of goods sold for 2017 was $6.19 billion and gross profit was $1.48 billion, compared to cost of goods sold and gross profit of $5.89 billion and $1.45 billion for 2016, respectively. As a percentage of net sales, gross profit was 19.3% and 19.7% for 2017 and 2016, respectively.

Non-cash interest expense for 2017 and 2016, which includes amortization of debt discounts and debt issuance costs, and interest related to uncertain tax positions, was $4.1 million and $7.8 million, respectively.

• | Loss on debt redemption of $123.9 million for 2016 was the result of a non-cash charge from the early redemption of the Company's 6.0% Convertible Senior Debentures due 2029 on September 15, 2016.

• | The effective tax rate for 2017 was 35.4%, compared to 23.1% for 2016. As adjusted, the effective tax rate for 2017 was 24.9%. The higher effective tax rate in the current year as compared to the effective tax rate for the prior year is due to $26.4 million of provisional discrete income tax expense related to the application of the TCJA.

• | Operating cash flow for 2017 was $149.1 million, compared to $300.2 million for 2016. The reduction in operating cash flow was primarily driven by changes in working capital to support sales growth. Free cash flow for 2017 was $127.6 million, or 67% of adjusted net income, compared to $282.2 million, or 154% of adjusted net income, for 2016. Additionally, the Company repurchased $100 million of shares in 2017.

Mr. Engel continued, "We are pleased with our return to growth in 2017 and our positive business momentum to start this year. We expect favorable economic conditions and positive growth in our end markets to continue in 2018. Our plan includes above-market performance, execution of our profitable growth initiatives, investments in our people and processes, and maintaining our cost and cash management discipline. As a result, we reaffirm our 2018 expectation of sales growth in the range of 3% to 6%, EPS of $4.40 to $4.90 per diluted share ($4.05 to $4.55 excluding the impact of U.S. tax reform legislation), and free cash flow generation of at least 90% of net income, all as outlined in our investor outlook call in December."

NON-GAAP FINANCIAL MEASURES
This earnings release includes certain non-GAAP financial measures. These financial measures include organic sales growth, gross profit, financial leverage, earnings before interest, taxes, depreciation and amortization, free cash flow, adjusted net income 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 of the aforementioned non-GAAP measures either focus on or exclude transactions impacting comparability of results, 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.

WESCO INTERNATIONAL, INC.
RECONCILIATION OF NON-GAAP FINANCIAL MEASURES
Note: Adjusted net income attributable to WESCO International, Inc. for the three and twelve month periods ended December 31, 2017, does not include provisional discrete income tax expense of $26.4 million associated with the application of the TCJA. For the year ended 2016, adjusted net income attributable to WESCO International, Inc. is defined as income (loss) before income taxes plus the 2016 third quarter loss on debt redemption, less the provision for income taxes excluding the 2016 third quarter benefit of such loss.
For the three and twelve month periods ended December 31, 2017, adjusted earnings per diluted share is computed by dividing adjusted net income by the weighted-average common shares outstanding and common share equivalents. For the year ended 2016, adjusted earnings per diluted share is computed by adding the loss per diluted share on the debt redemption and deducting the related income tax benefit per diluted share recognized in the third quarter of 2016 divided by the weighted-average common shares outstanding and common share equivalents.
The Company believes that these non-GAAP financial measures are useful to investors' overall understanding of the Company's current financial performance and provides a consistent measure for assessing the current and historical financial results.
