DALLAS, July 24, 2012 – Lennox International Inc. (NYSE: LII) today reported financial results for the second quarter of 2012. Financial results presented have been adjusted for discontinued operations related to the company’s sale of its Hearth business, which was completed in April 2012.

Revenue for the second quarter was $934 million, up 2% from the prior-year quarter. At constant currency, revenue was up 4%. Adjusted earnings per share from continuing operations was $0.96, up 12% from $0.86 in the prior-year quarter. On a GAAP basis, earnings per share from continuing operations was $0.93, up 9% from $0.85 in the prior-year quarter.

“Continued strong execution drove 11% revenue growth and 19% profit growth in our Residential business in the second quarter,” said Todd Bluedorn, Chairman and CEO of Lennox International. “Residential again realized strong growth in both new construction and replacement business, with warm weather comparable overall to the second quarter a year ago. Commercial revenue was up 5% at constant currency, with growth in both North America and Europe, and margin expanded 130 basis points to 15.0%. Refrigeration revenue was flat at constant currency on softness in Australia and Europe in the second quarter, but margin expanded 50 basis points to 10.3%. In Service Experts, revenue was down 8% at constant currency, and margin declined 70 basis points. Looking ahead for the company overall, we remain cautious on the global macroeconomic environment for the second half of the year but continue to be encouraged by the strength in our Residential and Commercial businesses, and Refrigeration backlog remains solid. We are raising our 2012 adjusted EPS from continuing operations guidance range, with a new midpoint of $2.50, and plan a minimum of $50 million of stock repurchases in the second half of this year.”

FINANCIAL HIGHLIGHTS

Revenue: Revenue for the second quarter was $934 million, up 2% from the prior-year quarter. At constant currency, revenue was up 4%. Volume and price were up, and mix was down from the prior-year quarter.

Gross Profit: Gross profit for the second quarter was $249 million, up 2% from the prior-year quarter. Gross margin was 26.6% compared to 26.7% in the prior-year quarter. Gross margin was negatively impacted by lower product mix and foreign exchange, partially offset by price and productivity initiatives. The annual adjustment for warranty reserves was neutral in the second quarter of 2012 compared to a favorable adjustment of $3 million in the prior-year quarter.

Income from Continuing Operations: Adjusted income from continuing operations in the second quarter was $49.6 million, or $0.96 earnings per share, compared to $46.8 million, or $0.86 earnings per share, in the prior-year quarter. Adjusted earnings from continuing operations for the second quarter of 2012 excludes an after-tax charge of $0.4 million for restructuring activities, $0.3 million after-tax for the net change in unrealized losses on open future contracts, and an after-tax charge of $0.7 million for other items, net.

On a GAAP basis, income from continuing operations for the second quarter was $48.2 million, or $0.93 earnings per share, compared to $46.1 million, or $0.85 earnings per share, in the prior-year quarter.

Loss from Discontinued Operations: The Hearth business was placed in discontinued operations in the first quarter of 2012 due to the planned sale by the company. The transaction was completed in April 2012. The loss from discontinued operations in the second quarter of 2012 was $3.5 million, or $0.06 per share, including transaction costs, compared to a loss of $1.1 million, or $0.02 per share, in the second quarter of 2011.

BUSINESS SEGMENT HIGHLIGHTS

Residential Heating & Cooling

Second quarter 2012 revenue in the Residential Heating & Cooling business segment was $412 million, up 11% from the prior-year quarter. Currency was neutral to revenue growth. Segment profit was $42 million, up 19% from the prior-year quarter. Segment profit margin was 10.2%, up 70 basis points. Results were primarily impacted by higher volume, favorable price, and sourcing and productivity initiatives, with offsets from lower mix and a less favorable warranty reserve adjustment than in the prior-year quarter.

Commercial Heating & Cooling

Revenue in the Commercial Heating & Cooling business segment was $201 million, up 1% from the prior-year quarter. At constant currency, revenue was up 5%. Segment profit was $30 million, up 11% from the prior-year quarter. Segment profit margin was 15.0%, up 130 basis points. Results were primarily impacted by higher volume, favorable price/mix, and sourcing and productivity initiatives, with offsets from higher freight expenses and negative foreign exchange.

Service Experts

Revenue in the Service Experts business segment was $133 million in the second quarter, down 9% from the prior-year quarter. At constant currency, revenue was down 8%. Segment profit was $2 million and segment profit margin was 1.5%, compared to segment profit of $3 million and segment profit margin of 2.2% in the prior-year quarter. Results were primarily impacted by lower volume, partially offset by lower SG&A expenses driven by productivity initiatives.

Segment profit was $21 million, flat with the prior-year quarter. Segment profit margin was 10.3%, up 50 basis points from the prior-year quarter.

FULL-YEAR OUTLOOK

The company is updating its revenue and EPS from continuing operations guidance ranges for 2012.

• Narrowing guidance for revenue growth at constant currency from 2-6% to a range of 3-6%. The company now assumes a negative 1 point impact from foreign exchange on a full-year basis, resulting in new revenue growth guidance of 2-5% at actual currency.

• Raising adjusted EPS from continuing operations guidance from $2.20-$2.60 to a range of $2.35-$2.65.

• Raising GAAP EPS from continuing operations guidance from $2.17-$2.57 to a range of $2.30-$2.60.

• Reiterating tax rate guidance of 33-34% for the full year.

• Reiterating average diluted share count guidance of approximately 51 million shares for the full year, including a minimum of $50 million of stock repurchases in the second half of 2012.
