Milwaukee, Wis.- January 27, 2012 - A. O. Smith Corporation (NYSE-AOS) today announced sales of $1.71 billion and earnings of $111.2 million, or $2.39 per share, from continuing operations for 2011.

Sales for 2011 grew 15 percent from $1.49 billion recorded in 2010. The recently acquired Lochinvar business added $75.9 million to sales, and sales of A. O. Smith branded products in China grew 29 percent to approximately $370 million for the year. Higher commercial water heater volumes in North America also contributed to higher sales.

Earnings from continuing operations for 2011 of $111.2 million, or $2.39 per share, included an after-tax gain of $12.9 million, or $.28 per share, related to shares of Regal Beloit Corporation (NYSE: RBC) hedged with an equity collar, a legal settlement with a component supplier and an increase to a warranty reserve associated with a similar component in Canada. The Lochinvar business contributed $.07 per share to full-year earnings, which included interest expense and $.10 per share from non-recurring professional fees related to the acquisition and purchase accounting charges. Earnings from continuing operations in 2010 were $57.1 million, or $1.24 per share, and included flood costs of $21.6 million or $.47 per share.

In the fourth quarter, the company earned $31.5 million or $.68 per share on sales of $475.8 million. Earnings from continuing operations for the same three-month period in 2010 were $20.5 million or $.44 per share on sales of $370.2 million.

"The A. O. Smith team did an excellent job of achieving this record performance in a less than ideal economy," Paul W. Jones, chairman and chief executive officer, observed. "Our acquisition of Lochinvar is achieving all that we expected, our growth in China continued at the high end of our expectations, and we are delighted with the acceptance of our products and growth in India. As a result, we were able to overcome global economic headwinds to achieve record earnings from continuing operations for the fifth time in the last six years. "

Operating Results
A number of factors contributed to the record-setting sales performance in addition to the incremental sales from Lochinvar. These included strong double digit sales growth in China, a full year of sales of the company's line of tankless water heaters in North America, volume increases in its US commercial water heaters primarily as a result of the anticipated air quality standard change in Southern California for 2012 and raw material related pricing actions. In addition, the company's water heater business in India more than doubled its sales over the prior year to nearly $19 million.

Operating profit increased to $196.5 million in 2011 compared with $132.9 million in 2010. Higher operating profit in 2011 was driven by organic volume growth in the company's China and US commercial businesses, as well as $13.2 million from Lochinvar. Operating profit from growth was partially offset by a decline in Canadian water heater volumes and losses at the company's water treatment business. Operating profit in 2011 included the net $3.0 million positive impact of the gain related to the settlement with the component supplier offset in part by the increase in the warranty reserve in Canada. Operating profit in 2010 included a one-time charge of $35.4 million associated with the May 2010 flood at the Ashland City, Tenn., facility. Operating margins of 11.5 percent in 2011 were higher than last year's operating margins of 8.9 percent, which included the impact from the flood.

Sales for the quarter were $475.8 million compared with $370.2 million in the fourth quarter 2010 and included $55.2 million from Lochinvar. Sales of A. O. Smith branded products in China grew over 30 percent from the previous year. Higher residential volumes and the pre-buy of commercial water heaters in the US also contributed to the sales increase.

Fourth quarter operating profit of $58.4 million included $10.2 million from Lochinvar and was $14.8 million higher than in the fourth quarter of 2010. Higher China and US water heater volumes and operating profit from Lochinvar were partially offset by higher steel costs and lower water heater volumes in Canada. Operating margin increased to 12.3 percent from the 11.8 percent operating margin in the fourth quarter of 2010.

Cash Flow and Share Buyback Authorization
The company generated $57.3 million in cash from continuing operating activities in 2011 which included the pre-tax impact from $175 million in pension contributions. Cash balances, largely held offshore, were $463.4 million, and outstanding debt was $461.6 million at the end of 2011. The company's leverage as measured by the ratio of debt to total capital increased to 30 percent at the end of 2011 compared with 23 percent at the end of last year as a result of borrowing to fund the purchase of Lochinvar.

During the fourth quarter, the company repurchased approximately 475,000 shares of common stock at an average price of $37.69 per share, representing a total of approximately $17.9 million. For the entire year, repurchases totaled 611,000 shares at an average price of $38.69 per share for a total of approximately $23.5 million. A total of approximately 890,000 shares remained in the existing repurchase authority at the end of 2011.

Outlook for 2012
"Although the U. S. economy is showing no signs of recovery, we continued to demonstrate that we can be successful in creating shareholder value without a benefit from new construction, and we believe A. O. Smith is well-positioned for future growth when new construction begins to recover," Jones said. "Our balance sheet and cash flow are strong and will support our active acquisition pipeline, our replacement water heater business in North America remains stable, and we are well established in China and India. The addition of Lochinvar and its potential to grow in both the domestic and international markets is another positive, which we expect will add $.40 to $.50 per share to our results in 2012."

"While we carefully watch for signs of an economic slowdown in China and are concerned about the ongoing weakness of domestic construction, we believe our China businesses will grow approximately twice as fast as China's GDP rate, and we expect no benefit from new construction in North America. We could see a decline in North American commercial volumes as a result of the pre-buy in the fourth quarter 2011 related to the Southern California air quality standard change, but we believe the balance of North American water heater volumes will be flat in 2012 because of the replacement business. We expect our Lochinvar business will grow in excess of 10 percent in 2012 compared with full year 2011, as the boiler industry continues to transition from lower efficiency to higher efficiency boilers. We expect improved operating performance from our India water heater and China water treatment businesses in 2012 compared with 2011. However, we estimate significantly higher pension expense in 2012 partially due to a lower discount rate and lower investment returns. All this considered, we estimate 2012 earnings will be in a range of $2.65 and $2.85 per share. This range does not include the potential impact from any future acquisitions or the impact of the RBC share activity."

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.
