A. O. Smith reports record earnings per share for 2009

Milwaukee, Wis.—A. O. Smith Corporation (NYSE:AOS) today announced the achievement of record earnings per share in 2009 in spite of lower revenues caused by the lingering housing crisis, a weak commercial construction market, and the global recession. Sales in 2009 were $2.0 billion, 14 percent lower than 2008 sales of $2.3 billion.

For the year, the company earned $81.3 million or $3.39 per share. Non-GAAP earnings, adjusted for the effect of the Smith Investment Company transaction which closed in April 2009, were $89.7 million, or $2.96 per share, 10 percent higher than non-GAAP earnings of $81.9 million or $2.70 per share earned in 2008. Growth in higher-margin China sales, aggressive cost management, lower raw material costs, and lower restructuring costs contributed to the improved results. Additionally, the company generated record cash flow from operations in 2009 of $267.6 million.

The company earned $22.7 million or $.74 per share in the fourth quarter of 2009 compared with non-GAAP earnings of $6.7 million or $.22 per share earned in the same period last year. Fourth quarter 2009 sales were $509.6 million, essentially flat compared with 2008 fourth quarter sales of $508.6 million.

“Our company and our employees performed extremely well under difficult circumstances last year,” Chairman and Chief Executive Officer Paul W. Jones said. “We recognized the onset of the global recession early, made the difficult decisions necessary to address the expected impact on the company, and then stuck by those decisions. The expense reduction and cash conservation programs we put in place had the desired effect, helping us maintain our profitability and generate significant cash flow throughout the year.”

“Our employees deserve a lot of credit for finding countless ways to reduce expenses and generate cash while remaining focused on our customers,” Jones added.

Water Products Company

Water Products sales decreased approximately five percent to $1.38 billion compared with 2008 sales of $1.45 billion. Lower sales of residential and commercial water heaters in the U. S. were partially offset by a 19 percent sales increase in China to more than $219 million.

Operating profit increased 11 percent to $148.9 million compared with profit of $134.7 million in 2008. Growth in China sales, aggressive cost management, and lower raw material costs contributed to the higher profits. Operating margin increased to 10.8 percent compared with 9.3 percent in 2008.

In the fourth quarter, Water Products sales of $362.2 million were approximately five percent higher than 2008 fourth quarter sales of $346.2 million, primarily the result of a 32 percent increase in China sales. Fourth quarter 2009 operating profit was $44.5 million, more than 50 percent higher than the $29.6 million profit for the same period in 2008, as a result of China sales growth, aggressive cost reduction programs, and lower raw material costs. Operating margin was 12.3 percent, an increase over the fourth quarter 2008 margin of 8.6 percent.

On Nov. 24, 2009, A. O. Smith concluded its purchase of 80 percent of the water treatment business of Tianlong Holding Co. Ltd. of Hong Kong. The newly formed company, A. O. Smith (Shanghai) Water Treatment Products Co., Ltd., will supply reverse osmosis water purification products to the China residential and commercial markets, as well as export markets throughout the world. A. O. Smith expects the new business to add between $0.10 and $0.15 to 2010 earnings per share.

Electrical Products

Sales in 2009 for Electrical Products decreased by 28 percent to $620.4 million as the weakened domestic housing market and the slowdown in the global commercial construction market reduced demand in all of its major market segments. Operating profit in 2009 declined to $32.5 million compared with $39.1 million in 2008. Aggressive cost reduction programs, lower raw material costs, and repositioning savings partially offset the significant impact of lower sales. The 2009 operating profit included restructuring income of $1.6 million primarily associated with the sale of a plant in China and an incremental $6.6 million LIFO benefit net of lower absorption of fixed costs associated with significant inventory reductions compared with 2008. Earnings in 2008 included $8.7 million of restructuring expense. Operating margin increased to 5.2 percent compared with 2008 operating margin of 4.6 percent.

6

In the fourth quarter, Electrical Products reported sales of $148.4 million, approximately nine percent lower than fourth quarter 2008 sales of $163.2 million. The weak housing market and soft global commercial construction activity contributed to the sales decline. Operating profit in the fourth quarter was $5.1 million compared with a loss of $5.2 million in the fourth quarter of 2008 as a result of cost reduction programs implemented early in 2009, lower raw material costs, and net LIFO benefit of $6.4 million. Fourth quarter 2008 earnings included restructuring charges of $2.9 million. Fourth quarter 2009 operating margin was 3.4 percent.

Cash flow and leverage

Record cash flow from operating activities in 2009 of $267.6 million was more than double the $98.4 million in cash generated in 2008. The strong focus on reducing working capital, most notably inventory reductions and improved accounts payable terms in China, drove the cash flow improvement. The company’s debt-to-capital ratio at the end of 2009 decreased to 24 percent from 34 percent at the end of 2008 despite the $77 million purchase price for the water treatment business in the fourth quarter. The company reduced debt by almost $100 million during the year.

Outlook

“There are a number of positive trends going into 2010, most notably continued growth in China and the start up of manufacturing in India, a full year of our new water treatment business, and evidence of improved demand in many of our global motor markets,” Jones said. “But, we remain cautious because of continued weakness in new commercial construction activity and rising commodity costs,” “Consequently, we expect earnings per share will range from $2.95 to $3.25 in 2010.”

A. O. Smith will broadcast a live conference call at 10:00 a.m. (Eastern Standard Time) today. The call can be heard on the company’s web site, www.aosmith.com. An audio replay of the call will be available on the company’s web site after the live event.

Smith Investment transaction impact to reported results

The 2008 and 2009 full year and fourth quarter 2008 results were impacted by required GAAP accounting related to the company’s previously announced transaction with Smith Investment Company (SICO), which closed April 22, 2009.

The company believes that providing non-GAAP information is beneficial to investors in understanding the current and historical operations of the company. A reconciliation of GAAP to non-GAAP earnings and earnings per share calculations is shown as part of the financial statements that accompany this release. Future quarterly financial statements will not be affected by the transaction; however, the company will provide non-GAAP financial information for historical comparison purposes.
