The Sherwin-Williams Company Reports 2012 Third Quarter and First Nine Months Financial Results

CLEVELAND, OHIO, October 25, 2012—The Sherwin-Williams Company (NYSE: SHW) announced its financial results for the third quarter and nine months ended September 30, 2012. Compared to the same periods in 2011, consolidated net sales increased $118.3 million, or 4.8%, to $2.60 billion in the quarter and increased $617.3 million, or 9.2%, to $7.31 billion in nine months due primarily to higher paint sales volume in our Paint Stores Group and selling price increases. Unfavorable currency translation rate changes decreased consolidated net sales approximately 2.2% in the quarter and nine months. Acquisitions increased consolidated net sales approximately 1.0% in the quarter and nine months.

Diluted net income per common share in the quarter increased to $2.24 per share from $1.71 per share in 2011 and increased in nine months to $5.37 per share from $3.98 per share last year. The third quarter and nine month increases in diluted net income per common share were due primarily to strong sales volumes and operating results driven primarily by Paint Stores Group. Unfavorable currency translation rate changes decreased diluted net income per common share by $.05 per share in the quarter and $.11 per share in nine months. Acquisitions had no significant effect on diluted net income per common share in the quarter and increased diluted net income per common share by $.02 per share in nine months.

Net sales in the Paint Stores Group increased 9.6% to $1.55 billion in the quarter and increased 14.2% to $4.16 billion in nine months due primarily to higher paint sales volume across all end market segments as well as higher year over year selling prices. Net sales from stores open for more than twelve calendar months increased 8.9% in the quarter and increased 13.6% in nine months over last year’s comparable periods. Paint Stores Group segment profit increased $63.7 million to $300.6 million in the quarter from $236.9 million last year and increased to $680.3 million in nine months from $512.4 million last year. The increases in segment profit in the quarter and nine months were due primarily to higher paint sales volume and higher selling prices partially offset by increases in raw material costs and selling, general and administrative expenses. Segment profit as a percent to net sales increased in the quarter to 19.3% from 16.7% last year and increased in nine months to 16.3% from 14.1% in 2011.

Net sales of the Consumer Group decreased 1.0% to $348.0 million in the quarter due primarily to lower volume sales to most of the Group’s retail customers mostly offset by acquisitions and selling price increases. Net sales increased 4.3% to $1.07 billion in nine months due primarily to selling price increases and acquisitions. Acquisitions increased net sales 5.3% and 2.4% in the quarter and nine months, respectively. Segment profit increased to $57.1 million in the quarter from $41.0 million last year and increased to $193.1 million in nine

months from $143.5 million last year due primarily to selling price increases and improved operating efficiencies partially offset by increasing raw material costs. As a percent to net external sales, segment profit increased in the quarter to 16.4% from 11.7% last year and increased in nine months to 18.1% from 14.0% in 2011. Acquisitions did not have a significant effect on segment profit in the quarter or nine months 2012.

The Global Finishes Group’s net sales stated in U.S. dollars decreased 1.0% to $491.8 million in the quarter due primarily to unfavorable currency translation rate changes and lower paint sales volume partially offset by selling price increases. Net sales increased 4.1% to $1.47 billion in nine months due primarily to selling price increases, acquisitions and higher paint sales volume partially offset by unfavorable currency translation rate changes. Acquisitions increased net sales in U.S. dollars by 2.4% in nine months. Unfavorable currency translation rate changes decreased net sales by 4.6% in the quarter and 4.2% in nine months. Stated in U.S. dollars, segment profit increased in the quarter to $36.4 million from $27.6 million last year due primarily to selling price increases partially offset by raw material cost increases and unfavorable foreign currency translation rate changes. In the first nine months, segment profit increased to $113.1 million from $77.3 million last year due primarily to selling price increases and higher paint sales volume partially offset by raw material cost increases. Acquisitions did not have a significant impact on segment profit in nine months 2012. Unfavorable currency translation rate changes decreased segment profit $5.1 million in the quarter and $9.5 million in nine months. As a percent to net external sales, segment profit was 7.4% in the quarter versus 5.5% last year and 7.7% in nine months compared to 5.5% in 2011.

The Latin America Coatings Group’s net sales stated in U.S. dollars decreased 4.0% to $208.7 million in the quarter and decreased 0.6% to $604.6 million in nine months due primarily to unfavorable currency translation rate changes partially offset by selling price increases and higher paint sales volume. Unfavorable currency translation rate changes decreased net sales by 13.8% in the quarter and 11.4% in nine months. Stated in U.S. dollars, segment profit increased to $21.9 million in the quarter from $15.9 million last year and increased to $51.1 million in nine months from $49.1 million last year due primarily to selling price increases and increased paint sales volume partially offset by raw material cost increases and unfavorable currency translation rate changes. Unfavorable foreign currency translation rate changes decreased segment profit $3.7 million in the quarter and $7.7 million in nine months. As a percent to net external sales, segment profit was 10.5% in the quarter versus 7.3% last year and 8.5% in nine months versus 8.1% in 2011.

The Company acquired 0.5 million shares of its common stock through open market purchases in the quarter and 3.8 million shares in nine months. The Company had remaining authorization at September 30, 2012 to purchase 17.25 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 on the continued positive sales volume and strong operating results of our Paint Stores Group. Selling price increases implemented across all segments in the previous twelve months are gaining traction against the higher raw material costs. The Paint Stores Group volume growth was strong across all end market segments. Our Consumer Group improved their operating results through operating efficiencies and selling price increases. Our Global Finishes and Latin America Coatings Groups are managing to improve their operating profit results despite the unfavorable effects of currency and the softening demand in their end markets.”

“We are continuing to invest in our business. In the first nine months, Paint Stores Group opened 28 net new locations. Our working capital ratio (accounts receivable plus inventories less accounts payable to sales) at September 30, 2012 was 12.7% compared to 13.3% last year. During the quarter, we continued to buy shares of our stock and pay a cash dividend of $.39 per common share. Our balance sheet remains flexible and is positioned for continued investments in our business.

“For the fourth quarter, we anticipate our consolidated net sales will increase in the mid single digits compared to the fourth quarter of 2011. At that anticipated sales level, we estimate diluted net income per common share in the fourth quarter to be in the range of $.98 to $1.18 per share compared to $.14 per share earned in the fourth quarter of 2011. For the full year 2012, we expect consolidated net sales to increase above 2011 levels by a high single digit percentage. With annual sales at that level, we have raised our expectation for diluted net income per common share for 2012 to be in the range of $6.35 to $6.55 per share compared to $4.14 per share earned in 2011.”
