The Sherwin-Williams Company Reports 2018 Third Quarter Financial Results

CLEVELAND, OHIO, October 25, 2018 - The Sherwin-Williams Company (NYSE: SHW) announced its financial results for the third quarter ended September 30, 2018. Compared to the same period in 2017, consolidated net sales increased $224.5 million, or 5.0%, to $4.73 billion in the quarter and increased $2.47 billion, or 22.4%, to $13.47 billion in nine months. The increase in the quarter was due primarily to higher paint sales volume in The Americas and Consumer Brands Groups and selling price increases. Currency translation rate changes decreased consolidated net sales by 1.1% in the third quarter. The increase in nine months was due primarily to incremental Valspar sales from the five months ended May 2018, higher paint sales volume in The Americas Group and selling price increases. Incremental Valspar sales from the five months ended May 2018 increased net sales 16.8% for the first nine months. As a result of the new revenue standard (ASC 606) adopted in the first quarter of 2018, certain advertising support that was previously classified as selling, general and administrative expenses is now classified as a reduction of revenue with no effect on net income. The new revenue standard reduced consolidated net sales approximately .8% in the quarter and first nine months.

Diluted net income per share in the quarter increased to $3.72 per share from $3.33 per share in 2017. Third quarter 2018 diluted net income per share included charges of $1.09 and $.87 per share from the California litigation and acquisition-related costs, respectively. The pre-tax charge for the California litigation of $136.3 million is one-third of the amount of the abatement fund, as recalculated by the trial court. Currency translation rate changes decreased diluted net income per share in the quarter by $.09 per share. In the quarter, we incurred incremental supply chain costs in an effort to keep pace with load-in demand of a new customer program while supporting what is traditionally our peak sales volume quarter, which reduced third quarter earnings per share by approximately $.16 per share. Third quarter 2017 diluted net income per

1

share included a $1.42 per share charge from acquisition-related costs. Diluted net income per share in the first nine months increased to $10.59 per share from $9.23 per share in 2017. First nine months 2018 diluted net income per share included charges of $3.05, $1.09, and $.25 per share from acquisition-related costs, the California litigation and environmental expense provisions, respectively. Currency translation rate changes decreased diluted net income per share in the first nine months 2018 by $.09 per share. Diluted net income per share for the first nine months 2017 included a $.44 per share charge for discontinued operations and a $2.22 per share charge from acquisition-related costs.

Net sales in The Americas Group increased 5.0% to $2.67 billion in the quarter and increased 6.4% to $7.37 billion in nine months due primarily to higher architectural paint sales volume across most end market segments and selling price increases. Currency translation rate changes decreased Group net sales by 1.4% and .7% in the quarter and nine months, respectively. Net sales from stores in the U.S. and Canada open for more than twelve calendar months increased 5.2% in the quarter and 5.7% in nine months over last year’s comparable periods. Segment profit increased $52.2 million to $577.7 million in the quarter and increased $121.5 million to $1.49 billion in nine months due primarily to higher paint sales volume and selling price increases, partially offset by increased raw material costs. Currency translation rate changes decreased segment profit by 1.4% and .8% in the quarter and nine months, respectively. Segment profit as a percent to net sales increased in the quarter to 21.7% from 20.7% last year. In the first nine months, segment profit as a percent to net sales increased to 20.1% from 19.7% last year.

Net sales of the Consumer Brands Group increased 6.5% to $770.5 million in the quarter and increased 39.3% to $2.20 billion in nine months. The increase in the quarter was due primarily to a new customer program and selling price increases, partially offset by lower volume sales to some of the Group’s retail customers. The increase in nine months was due primarily to incremental Valspar sales and selling price increases, partially offset by lower volume sales to some of the Group’s retail customers. Incremental Valspar sales from the five months ended May 2018 increased Group net sales 36.6% for the first nine months. Currency translation rate changes had no material impact on net sales in the quarter and nine months. The new revenue standard reduced Group net sales by 4.7% and 5.5% in the quarter and nine months, respectively. Segment profit increased to $83.9 million in the quarter from $70.4 million last year due primarily to selling price increases and reduced impacts of purchase accounting, partially offset by increased raw material costs and incremental supply chain costs in an effort to keep pace with load-in demand of a new customer program. As a percent of net external sales, segment profit increased in the quarter to 10.9% from 9.7% last year. Purchase accounting expense in the quarter was $26.0 million, a decrease of $28.5 million from last year. In the first nine months, segment profit increased to $249.1 million from $202.4 million last year. Segment profit for the first nine months was increased by incremental Valspar operations profit for the first five months of $75.8 million. Purchase accounting net expense through nine months was $86.4 million, an increase of $11.6 million over last year. As a percent of net external sales, segment profit decreased in the first nine months to 11.3% from 12.8% last year due primarily to increased raw material costs, increased purchase accounting expense, and incremental supply chain costs in an effort to keep pace with load-in demand.

The Performance Coatings Group’s net sales stated in U.S. dollars increased 4.2% to $1.29 billion in the quarter and increased 56.4% to $3.89 billion in nine months. The increase in the quarter was due primarily to selling price increases and continued strong demand in most of our North American businesses. The increase in nine months was due primarily to the inclusion of Valspar sales and selling price increases. Incremental Valspar sales from the five months ended May 2018 increased Group net sales 51.1% for the first nine months. Currency translation rate changes decreased Group net sales by 1.1% in the quarter and had an immaterial impact in the nine months. Stated in U.S. dollars, segment profit increased in the quarter to $104.9 million from $59.6 million last year due primarily to selling price increases and reduced impacts of purchase accounting, partially offset by increased raw material costs. Currency translation rate changes decreased segment profit $3.3 million in the quarter. As a percent to net external sales, segment profit in the quarter increased to 8.1% from 4.8% last year. Purchase accounting expense in the quarter was $55.4 million, a decrease of $46.5

2

million from last year. Stated in U.S. dollars, segment profit increased in the first nine months to $339.8 million from $179.1 million last year due primarily to the inclusion of Valspar operations, partially offset by higher purchase accounting costs. Currency translation rate changes decreased segment profit by $1.2 million in the first nine months. Segment profit for the first nine months was increased by incremental Valspar operations profit for the first five months of $184.3 million. Purchase accounting expense through nine months was $160.6 million, an increase of $19.6 million over last year. As a percent of net external sales, segment profit increased in the first nine months to 8.7% from 7.2% last year.

The Company purchased 925,000 shares of its common stock in the nine months ended September 30, 2018. At September 30, 2018, the Company had remaining authorization to purchase 10.73 million shares of its common stock through open market purchases. In the first nine months, the Company opened 43 net new store locations in The Americas Group. Net operating cash improved 13.7% to $1.43 billion in the nine months ended September 30, 2018. This strong cash generation allowed us to return over $600 million to our shareholders in the form of dividends and share buyback, while paying down debt of $850 million.

Commenting on the third quarter, John G. Morikis, Chairman, President and Chief Executive Officer, said, “We continue to make great progress on the integration of Sherwin-Williams and Valspar into a faster growing, more profitable enterprise, but our results in the third quarter don’t fully reflect that progress. Revenue growth slowed from the pace set in the second quarter, due primarily to slower growth in some North American architectural businesses, a sequential slow-down in some of our industrial businesses in China and Europe and unfavorable currency translation rate changes. The price increases implemented over the past 12 months have largely kept pace with accelerating raw material inflation on a consolidated basis, but some of our Performance Coatings businesses continue to lag in that effort. During the quarter, our Global Supply Chain team incurred incremental costs in an effort to keep pace with load-in demand during what is traditionally our peak sales volume quarter. These unfavorable impacts were mostly offset by a lower than anticipated effective tax rate on both a reported and adjusted basis. Our effective tax rates on reported net income and adjusted net income were 14.9 percent and 18.5 percent, respectively. While our results in the quarter fell short of our initial expectations, we remain confident in, and excited about, the long term value created by the combination of these two great companies.

“For the fourth quarter, we anticipate our consolidated net sales will increase a mid-single digit percentage compared to last year’s fourth quarter. For the full year 2018, we expect our consolidated net sales will increase by a high teen percentage, including incremental Valspar sales of $1.85 billion for the first five months of 2018, compared to the full year 2017. With annual sales at this level, we are updating our full year 2018 diluted net income per share to be in the range of $13.85 to $14.00 per share, including charges of $3.86 per share for acquisition-related costs, $1.09 per share for the California litigation, and $.25 per share for environmental expense provisions. Diluted net income per share in 2017 was $18.67 per share, including a one-time benefit of $7.04 per share from deferred income tax reductions, a one-time charge of $.44 per share for discontinued operations and a charge of $3.00 per share for acquisition-related costs. The incremental supply chain costs incurred in the third quarter make it unlikely we will reach the higher end of the full year adjusted diluted net income per share range provided last quarter. We are therefore narrowing our full year 2018 adjusted diluted net income per share to be in the range of $19.05 to $19.20 per share, excluding acquisition costs, the charge for the California litigation, and environmental expense provisions, compared to $15.07 per share on a comparable basis in 2017. We now expect our 2018 effective tax rate to be approximately nineteen to twenty percent.”
