The Sherwin-Williams Company Reports 2013 Third Quarter and First Nine Months Financial Results

CLEVELAND, OHIO, October 25, 2013 - The Sherwin-Williams Company (NYSE: SHW) announced its financial results for the third quarter and nine months ended September 30, 2013. Compared to the same periods in 2012, consolidated net sales increased $244.2 million, or 9.4%, to $2.85 billion in the quarter and increased $415.9 million, or 5.7%, to $7.73 billion in nine months due primarily to higher paint sales volume in our Paint Stores Group. Acquisitions increased consolidated net sales 1.1% in the quarter and increased consolidated net sales 0.9% in nine months. Unfavorable currency translation rate changes decreased consolidated net sales 0.8% in the quarter and decreased consolidated net sales 0.7% in nine months.

Diluted net income per common share in the quarter increased to $2.55 per share from $2.24 per share in 2012, including a 2013 charge of $.13 per share resulting from government tax assessments related to our Brazilian operations. Diluted net income per common share increased in nine months to $6.11 per share from $5.37 per share last year, including 2013 charges of $.21 per share related to the Brazil tax assessments. The increases in third quarter and nine months diluted net income per common share were due primarily to improved operating results of the Paint Stores, Consumer and Global Finishes Groups. Currency translation rate changes increased diluted net income per common share by $.02 per share in the quarter and decreased diluted net income per common share by $.02 per share in nine months. Acquisitions decreased diluted net income per common share by $.02 in the quarter and had no impact on diluted net income per common share in nine months.

Net sales in the Paint Stores Group increased 13.5% to $1.76 billion in the quarter and increased 9.0% to $4.54 billion in nine months due primarily to higher architectural paint sales volume across all end market segments. Net sales from stores open for more than twelve calendar months increased 10.9% in the quarter and increased 7.4% in nine months over last year’s comparable periods. Paint Stores Group segment profit increased $58.8 million to $359.4 million in the quarter from $300.6 million last year and increased $141.8 million to $822.0 million in nine months from $680.3 million last year due primarily to higher paint sales volume partially offset by increases in selling, general and administrative expenses. Segment profit as a percent to net sales increased in the quarter to 20.4% from 19.3% last year and increased in nine months to 18.1% from 16.3% in 2012.

Net sales of the Consumer Group increased 5.4% to $366.8 million in the quarter due primarily to timing of seasonal shipments to some customers. Net sales increased 0.3% to $1.07 billion in nine months due primarily to higher sales in the quarter and acquisitions partially offset by the previously disclosed elimination of a portion of a paint program with a large retail customer. Acquisitions increased net sales 0.2% in the quarter and increased net sales 2.7% in nine months. Segment profit increased to $73.1 million in the quarter from $57.1 million last year and increased to $206.1 million in nine months from $193.1 million last year due primarily to higher volume sales and improved operating efficiencies. Acquisitions had no significant impact on segment profit in the quarter and increased segment profit $1.8 million in nine months. As a percent to net external sales, segment profit increased in the quarter to 19.9% from 16.4% last year and increased in nine months to 19.3% from 18.1% in 2012.

The Global Finishes Group’s net sales stated in U.S. dollars increased 3.2% to $507.3 million in the quarter and increased 2.3% to $1.51 billion in nine months due primarily to selling price increases and acquisitions. Acquisitions increased net sales in U.S. dollars by approximately 1.3% in the quarter and nine months. Currency translation rate changes decreased net sales by 0.4% in the quarter and nine months. Stated in U.S. dollars, segment profit increased in the quarter to $44.5 million from $36.4 million last year and increased in nine months to $132.9 million from $113.1 million last year due primarily to improved operating efficiencies and selling price increases. Currency translation rate changes increased segment profit $3.4 million in the quarter and had no significant impact in nine months. Acquisitions had no significant impact on segment profit in the quarter or nine months. As a percent to net external sales, segment profit was 8.8% in the quarter versus 7.4% last year and 8.8% in nine months compared to 7.7% in 2012.

The Latin America Coatings Group’s net sales stated in U.S. dollars was flat at $208.6 million in the quarter due primarily to selling price increases and higher paint sales volume offset by unfavorable currency translation rate changes. Nine month net sales stated in U.S. dollars increased 0.9% to $610.3 million due primarily to selling price increases partially offset by unfavorable currency translation rate changes. Unfavorable currency translation rate changes decreased net sales by 8.9% in the quarter and decreased net sales by 6.2% in nine months. Stated in U.S. dollars, segment profit decreased to a loss of $1.0 million in the quarter from income of $21.9 million last year due primarily to charges relating to a Brazil import duty tax assessment partially offset by selling price increases and higher paint sales volume. Stated in U.S. dollars, segment profit in nine months decreased to $20.7 million from $51.1 million last year due primarily to the Brazil tax assessments and unfavorable currency translation rate changes partially offset by selling price increases. Charges of $19.8 million and $31.6 million were recorded in the quarter and nine months, respectively. These charges were primarily related to import duty taxes paid to the Brazilian government related to the handling of import duties on products brought into the country for the years 2006 through 2012. The Company elected to pay the taxes through an existing voluntary amnesty program offered by the government to resolve these issues rather than contest them in court. Foreign currency translation rate changes had no significant impact on segment profit in the quarter and reduced segment profit $1.9 million in nine months. As a percent to net external sales, segment profit decreased in the quarter to negative 0.5% from 10.5% last year and decreased in nine months to 3.4% from 8.5% in 2012.

The Company acquired 1.5 million shares of its common stock through open market purchases in the quarter and 2.8 million shares in nine months. The Company had remaining authorization at September 30, 2013 to purchase 13.65 million shares.

Commenting on the financial results, Christopher M. Connor, Chairman and Chief Executive Officer, said, “We are pleased to report record sales and earnings per share in the third quarter and first nine months of 2013 on the continued positive sales volume and strong operating results of our Paint Stores Group. The Paint Stores Group architectural volume growth was strong across all end market segments. Our Consumer Group improved their operating margins through better than expected sales and improved operating efficiencies. Our Global Finishes Group continues to improve its operating margins through improved operating efficiencies and good cost control. The Latin America Coatings Group is minimizing the impact on its core operating margins through selling price increases and good cost control despite the difficult environment in which they are operating.

“We are continuing to invest in our business. In the first nine months, Paint Stores Group opened 42 net new stores. In September, we completed the acquisition of the Comex U.S. and Canada businesses which added an additional 306 stores. Our working capital ratio (accounts receivable plus inventories less accounts payable to sales) at September 30, 2013 was 12.5% compared to 12.7% last year. During the quarter, we continued to buy shares of our stock and we increased the dividend rate to $.50 from $.39 last year. Our balance sheet is positioned well for the anticipated closing of the Comex Mexico acquisition and other investments in our business.

“For the fourth quarter, we anticipate our core consolidated net sales will increase five to seven percent compared to last year’s fourth quarter. At that anticipated sales level, we estimate core diluted net income per common share in the fourth quarter to be in the range of $1.29 to $1.39 per share compared to $.65 per share earned in the fourth quarter of 2012. We anticipate our Comex acquisition will increase net sales $95 million to $105 million and negatively impact diluted net income per common share $.20 to $.40 per share in the fourth quarter. For the full year 2013, we expect consolidated net sales to increase above 2012 levels by a mid single digit percentage. With annual sales at that level, we are updating our guidance for diluted net income per common share for 2013 to an expected range of $7.00 to $7.30 per share compared to $6.02 per share earned in 2012.”

Regulation G Reconciliation

Management of the Company believes that investors’ understanding of the Company’s operating performance is enhanced by the disclosure of diluted net income per common share excluding the Comex acquisition. This adjusted earnings per share measurement is not in accordance with U.S. generally accepted accounting principles (GAAP). It should not be considered a substitute for earnings per share computed in accordance with U.S. GAAP and may not be comparable to similarly titled measures reported by other companies. The following table reconciles the anticipated diluted net income per common share computed in accordance with U.S. GAAP to the anticipated diluted net income per common share excluding the Comex acquisition for the quarter and year ended December 31, 2013:
