CLEVELAND, OHIO, April 22, 2010 — The Sherwin-Williams Company (NYSE: SHW) announced its financial results for the first quarter ended March 31, 2010. Compared to the same period in 2009, consolidated net sales increased $14.8 million, or 1.0%, to $1.565 billion in the quarter due to the favorable impact of foreign currency translation rate changes partially offset by a decline in domestic paint sales volume. Favorable currency translation rate changes increased consolidated net sales 2.9% in the quarter.

Diluted net income per common share in the quarter, including a one-time increase in income tax expense of $.10 per share relating to the Health Care and Education Reconciliation Act of 2010 passed by Congress on March 25, 2010, decreased to $.30 per share from $.32 per share in 2009. The unfavorable impact of the health care legislation was not included in our guidance for first quarter or full year 2010 diluted net income per share issued on January 26, 2010. Foreign currency rate changes and acquisitions had no significant impact on diluted net income per common share in the quarter.

Net sales in the Paint Stores Group decreased 5.3% to $850.9 million in the quarter due primarily to a decline in paint sales volume and corresponding weakness in non-paint sales. During the quarter, net sales from stores open for more than twelve calendar months decreased 5.4% over last year’s first quarter. Paint Stores Group segment profit decreased to $47.8 million in the quarter from $56.6 million last year due primarily to lower sales volume and raw material cost increases partially offset by reductions in selling, general and administrative expenses. Segment profit as a percent to net sales decreased to 5.6% from 6.3% last year due to volume.

Net sales of the Consumer Group increased 1.4% to $292.1 million in the quarter due primarily to new product introductions partially offset by soft DIY demand at some of the Segment’s retail customers. Segment profit increased to $37.5 million in the quarter from $30.2 million last year. Segment profit in the quarter increased as a percent to net external sales to 12.8% from 10.5% last year due primarily to good cost control and cost savings realized from previous year plant rationalizations partially offset by increasing raw material costs and reduced fixed cost absorption from lower manufacturing and distribution volume.

The Global Finishes Group’s net sales stated in U.S. dollars increased 16.2% to $421.1 million in the quarter due primarily to favorable currency translation rate changes and higher paint sales volume. In the quarter, favorable currency translation rate changes increased net sales of the Global Finishes Group in U.S. dollars by 10.3%. Stated in U.S. dollars, Global Finishes Group segment profit in the quarter increased to $23.0 million from $5.3 million in last year’s first quarter due primarily to increased paint sales volume and good expense control. Foreign currency rate changes reduced segment profit in the quarter by $1.1 million. As a percent to net external sales, segment profit was 5.5% in the quarter versus 1.5% last year.

The Company acquired 400,000 shares of its common stock through open market purchases in the quarter and had remaining authorization at March 31, 2010 to purchase 10.35 million shares.

Commenting on the financial results for the first quarter, Christopher M. Connor, Chairman and Chief Executive Officer, said, “Sales in the quarter were slightly stronger than we anticipated, although domestic demand remains soft. Paint Stores Group volume decreased at the lowest rate since the fourth quarter 2008 due to improvements in certain architectural segments. In the Global Finishes Group, we are pleased with the growth in architectural, OEM, and automotive finishes sales volume. Our Consumer Group improved their operating results through disciplined cost management and realizing the benefits from prior year site rationalizations. Our operating segment management teams continue to control costs and have announced or implemented price increases to help mitigate increasing raw material costs.

“We continued to invest in our business by opening 3 net new locations in the Paint Stores Group and 1 in our Global Finishes Group. For the year, we expect our Paint Stores Group to open 40 to 50 new stores while slowing the rate at which we close redundant store locations. In April, we completed the acquisition of Sayerlack Industrial Wood Coatings, a leading coatings innovator in the joinery, furniture, and cabinets markets. We made further progress in our management of working capital, reducing our working capital ratio to 12.4% of sales from 12.8% of sales in the first quarter of last year. During the quarter, we used our cash to continue to buy shares of stock and we increased the dividend rate to $.36 from $.355 last year. Our balance sheet remains fiscally sound and capable of financing our planned business operations and growth in the foreseeable future.

“For the second quarter, we anticipate that our consolidated net sales will increase a high single digit percentage compared to last year’s second quarter. We expect diluted net income per common share for the second quarter to be in the range of $1.55 to $1.70 per share compared to $1.35 per share in 2009. For the full year 2010, we expect consolidated net sales to increase above 2009 levels by a mid-to-high single digit percentage. With annual sales at that level, we have raised our expectation for diluted net income per common share for 2010 to be in the range of $4.20 to $4.60 per share, including the unfavorable tax impact of health care legislation, compared to $3.78 per share earned in 2009.”
