The Sherwin-Williams Company Reports 2012 Year-end Financial Results

CLEVELAND, OHIO, January 31, 2013 - The Sherwin-Williams Company (NYSE: SHW) announced its financial results for the year and fourth quarter ended December 31, 2012. Compared to the same periods in 2011, consolidated net sales increased $768.8 million, or 8.8%, to $9.53 billion in the year and increased $151.4 million, or 7.3%, to $2.22 billion in the quarter due primarily to higher paint sales volume in our Paint Stores Group and selling price increases. Acquisitions increased consolidated net sales approximately 0.9% in the year and in the quarter. Unfavorable currency translation rate changes decreased consolidated net sales 1.8% in the year and 1.0% in the quarter.

Diluted net income per common share in the year increased to $6.49 per share, including asset impairment charges of $.02 per share, from $4.14 per share in 2011, including asset impairment charges of $.03 per share and an increase in income tax expense of $.70 per share relating to the IRS settlement. Unfavorable currency translation rate changes decreased diluted net income per common share by $.13 per share for the year. Acquisitions had no impact on diluted net income per common share for the year. Diluted net income per common share was $1.12 per share in the quarter compared to $.14 per share a year ago, including the asset impairment charges and the IRS settlement noted above for the fourth quarter 2012 and 2011. Acquisitions and currency translation rate changes had an unfavorable impact on fourth quarter diluted net income per common share resulting in a reduction of $.03 per share.

Net sales in the Paint Stores Group increased 13.2% to $5.41 billion in the year and increased 9.8% to $1.25 billion in the quarter 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 12.5% in the year and 9.2% in the quarter over last year’s comparable periods. Paint Stores Group segment profit increased to $861.8 million in the year from $645.7 million last year and increased to $181.5 million in the quarter from $133.4 million last year. The increases in segment profit in the year and quarter were due primarily to higher paint sales volume and higher selling prices partially offset by increases in raw material costs and in selling, general, and administrative expenses. Segment profit as a percent to net sales increased in the year to 15.9% from 13.5% in 2011 and increased in the quarter to 14.6% from 11.8% last year. Trademark impairment charges for the planned conversion of various acquired brands were $3.4 million in the year and fourth quarter 2012 compared to $4.7 million in the year and fourth quarter 2011.

Net sales of the Consumer Group increased 3.7% to $1.32 billion in the year due primarily to selling price increases and acquisitions. Net sales increased 1.4% to $255.8 million in the quarter due primarily to acquisitions partially offset by lower volume sales to most of the Group’s retail customers. Acquisitions increased net sales 3.2% and 6.5% in the year and quarter, respectively. Segment profit increased to $216.4 million in the year from $173.7 million last

year due primarily to selling price increases and improved operating efficiencies partially offset by increases in raw material costs. Segment profit decreased to $23.3 million in the quarter from $30.2 million last year due primarily to a more normal seasonal decline in our internal finished goods inventory compared to the fourth quarter 2011 and increases in raw material costs that were partially offset by selling price increases. As a percent to net external sales, segment profit increased in the year to 16.4% from 13.6% in 2011 and decreased in the quarter to 9.1% from 12.0% last year.

The Global Finishes Group’s net sales stated in U.S. dollars increased 4.4% to $1.96 billion in the year due primarily to selling price increases, higher paint sales volume, and acquisitions partially offset by unfavorable currency translation rate changes. In the quarter, the Global Finishes Group’s net sales increased 5.1% to $487.1 million due primarily to selling price increases and higher paint sales volume partially offset by unfavorable currency translation rate changes. In the year, acquisitions increased net sales in U.S. dollars by 1.8%. Unfavorable currency translation rate changes decreased net sales 3.5% and 1.4% in the year and quarter, respectively. Stated in U.S. dollars, segment profit in the year increased to $147.2 million from $90.3 million last year and increased in the quarter to $34.1 million from $13.0 million last year due primarily to selling price increases, increased paint sales volume, and good expense control partially offset by increases in raw material costs. Unfavorable foreign currency translation rate changes and acquisitions decreased segment profit $11.9 million in the year and $3.4 million in the quarter. As a percent to net external sales, segment profit was 7.5% in twelve months 2012 compared to 4.8% in 2011 and 7.0% in the quarter versus 2.8% last year. Trademark impairment charges were $0.7 million in the year and fourth quarter 2012 compared to $0.8 million in the year and fourth quarter 2011.

The Latin America Coatings Group’s net sales stated in U.S. dollars increased 0.9% to $836.1 million in the year and increased 5.2% to $231.5 million in the quarter due primarily to selling price increases and higher paint sales volume partially offset by unfavorable currency translation rate changes. Unfavorable currency translation rate changes decreased net sales by 10.2% and 6.7% in the year and quarter, respectively. Stated in U.S. dollars, segment profit in the year increased to $81.2 million compared to $75.5 million last year and increased to $30.1 million in the quarter from $26.4 million last year due primarily to selling price increases and increased paint sales volume partially offset by increases in raw materials costs and unfavorable foreign currency translation rate changes. Foreign currency translation rate changes reduced segment profit $9.7 million in the year and decreased segment profit $2.0 million in the quarter. As a percent to net external sales, segment profit was 9.7% in twelve months compared to 9.1% in 2011 and 13.0% in the quarter versus 12.0% in the fourth quarter last year.

The Company acquired 0.8 million shares of its common stock through open market purchases in the quarter bringing our total purchased to 4.60 million shares in the year. The Company had remaining authorization at December 31, 2012 to purchase 16.45 million shares.

Commenting on the financial results, Christopher M. Connor, Chairman and Chief Executive Officer, said, “We are pleased to report record highs for multiple financial measures in 2012, including sales, earnings per share, net operating cash and earnings before interest, taxes, depreciation and amortization. All of our operating segments contributed to the record year with increases in sales and operating profit, lead by our Paint Stores Group.”

“Over the past year, our Paint Stores Group had positive sales volume across all end market segments and drove strong operating results. Our Consumer Group improved operating results through operating efficiencies and selling price increases. The Global Finishes Group continued improving segment profit as a percent to sales through increased selling prices and efficiencies gained from the continued integration of prior year acquisitions. Our Latin America Coatings Group managed to improve their operating results despite the unfavorable effects of currency and the softening of demand in their end markets.

“We continue to generate significant cash from operations allowing us to invest in the business and return a substantial portion to our shareholders. In 2012, we generated net operating cash flow of $887.9 million. Our working capital ratio (accounts receivable plus inventories less accounts payable to sales), excluding acquisitions, at December 31, 2012 was 10.7% compared to 10.9% last year. We are continuing to invest in our business by expanding the Paint Stores platform. In 2012, we added 70 net new stores, finishing the year with 3,520 stores in operation. During the year, we continued to buy our stock on the open market and paid an annual cash dividend of $1.56 per common share. Our balance sheet is positioned well for the anticipated closing of the Comex acquisition and other investments in our business enabling us to borrow approximately $1.0 billion in debt in the fourth quarter at an average blended rate of 2.1%.

“In the first quarter of 2013, we anticipate our consolidated net sales will increase a low single digit percentage compared to the first quarter of 2012. At that anticipated sales level, we estimate diluted net income per common share in the first quarter of 2013 will be in the range of $1.03 to $1.13 per share compared to $.95 per share earned in the first quarter of 2012. 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 anticipate diluted net income per common share for 2013 will be in the range of $7.45 to $7.55 per share compared to $6.49 per share earned in 2012. These results exclude any effect from the proposed Comex acquisition.”
