David H. Dingus, president and chief executive officer of AZZ incorporated, commented, “As we reported last quarter, opportunities are increasing, but pricing remains a challenge due to competitive forces. This has and will continue to impact our backlog growth as we continue to adhere to our margin targets for new business. We are pleased that our book to ship ratio was strong despite these competitive conditions as we strive to improve the margins in our backlog. Quarterly revenues reflected improvement in both segments and is encouraging. Operating margins, while below our prior year, were in line with our internal expectations. Galvanizing had another quarter of solid organic and acquisition growth. Our customers remain concerned as to what the domestic and international market growth will be. Effective execution on all our opportunities, expansion of served domestic and international markets, and seeking out additional product and market opportunities to further enhance our strategic position will continue to be the focus and emphasis of our activities.”

Based upon the evaluation of information currently available to management, we are revising our fiscal year 2012 guidance for revenues to be in the range of $450 to $475 million. Our earnings guidance is revised and anticipated to be within the range of $2.90 to $3.10 per diluted share. The previously issued guidance was for revenues to be in the range of $425 to $450 million and that fully diluted earnings per share would be in the range of $2.70 to $3.05. Our guidance does include the increased interest expense in fiscal 2012 of $0.34 per diluted share associated with the $125 million of Senior Private Placement Notes issued on January 20, 2011.
