DALLAS, October 22, 2012 – Lennox International Inc. (NYSE: LII) today reported financial results for the third quarter of 2012. Financial results presented have been adjusted for discontinued operations related to the company’s previously announced plans to divest the Service Experts business.

Revenue for the third quarter was $810 million, up 1% from the prior-year quarter. At constant currency, revenue was up 3%. Adjusted earnings per share from continuing operations was $0.97, up 23% from $0.79 in the prior-year quarter. On a GAAP basis, earnings per share from continuing operations was $0.97, up 47% from $0.66 in the prior-year quarter.

“Our Residential business continued its strong growth in both replacement and new construction markets in the third quarter, with revenue up 9% and profit up 20%,” said Chairman and CEO Todd Bluedorn. “In our Commercial business, profit was up 5% on 1% revenue growth at constant currency – with North America down low single digits on the timing of national account business and Europe up high single digits. In Refrigeration, revenue was down 6% at constant currency, also impacted by the timing of national account business in North America as well as some slowing in Europe – our other regions saw nice growth. Strong execution on operational initiatives drove 22% profit growth in Refrigeration. Overall for the company, revenue was up 3% at constant currency in the quarter, with total segment profit up 19%. Looking ahead, we expect our momentum in Residential to continue. Backlog and order rates in our Commercial and Refrigeration businesses look solid overall, and we expect an improved national account environment in the fourth quarter. For the full year, our guidance for adjusted EPS from continuing operations is now $2.60-$2.80, with the midpoint up 20% from $2.25 last year.”

Segment profit was $38 million, up 20% from the prior-year quarter. Segment profit margin was 9.8%, up 100 basis points.

Segment profit was $33 million, up 5% from the prior-year quarter. Segment profit margin was 14.8%, up 90 basis points.

FULL-YEAR OUTLOOK

• Raising GAAP EPS from continuing operations guidance from $2.30-$2.60 to a range of $2.55-$2.75.
