- Fourth Quarter GAAP Diluted EPS from Continuing Operations of $0.53;

Non-GAAP Diluted EPS from Continuing Operations of $0.57 -

NORWALK, CONNECTICUT, February 23, 2012 – EMCOR Group, Inc. (NYSE: EME) today reported results for the fourth quarter ended December 31, 2011.

As previously announced, the Company completed the sale of its Canadian subsidiary, Comstock Canada, in August 2011.  Accordingly, Comstock’s results for the 2011 fourth quarter and all prior periods have been classified as discontinued operations.

For the fourth quarter of 2011, net income from continuing operations attributable to EMCOR was $36.3 million, or $0.53 per diluted share. Excluding a pre-tax, non-cash impairment charge of $3.8 million, or $0.03 per diluted share after-tax, related to the change in value of certain customer relationships and trade names within the Company’s U.S. facilities services segment, non-GAAP net income from continuing operations for the fourth quarter of 2011 was $38.6 million, or $0.57 per diluted share. Net income from continuing operations for the fourth quarter of 2010 was $41.7 million, or $0.61 per diluted share.

Revenues increased 16.7% to $1.52 billion in the fourth quarter of 2011, compared to revenues of $1.30 billion in the year ago period.  Organic revenue growth in the quarter was 7.3%.

Including the above-mentioned non-cash impairment charge, operating income for the fourth quarter of 2011 was $62.4 million, or 4.1% of revenues. Excluding the non-cash impairment charge, the Company’s non-GAAP operating income for the fourth quarter of 2011 was $66.2 million, or 4.4% of revenues. For the fourth quarter of 2010, the Company reported operating income of $70.8 million, or 5.4% of revenues, which included strong profitability within the Company’s U.S. mechanical construction and facilities services segment as a result of work obtained during the pre-recessionary period and the favorable settlement of an outstanding claim on a project. The Company recorded restructuring expenses of $0.1 million in the 2011 fourth quarter and $1.5 million in the 2010 fourth quarter.

Selling, general and administrative expenses (“SG&A”) were $148.0 million, or 9.7% of revenues, in the fourth quarter of 2011, compared to $129.2 million, or 9.9% of revenues, in the 2010 fourth quarter.

Net income for the fourth quarter of 2011 of $36.7 million included $0.3 million of income from discontinued operation.  For the fourth quarter of 2010, the Company reported net income of $40.0 million, which includes a loss of $1.7 million from discontinued operation.

Excluding Comstock Canada’s backlog from the current quarter and prior periods, the Company’s backlog as of December 31, 2011 was $3.33 billion, an increase of 7.1% over backlog of $3.11 billion a year ago.  This increase reflects growth in the commercial, institutional and industrial sectors, which offset the declines in the healthcare, hospitality/gaming, water/wastewater and transportation sectors.  Commercial backlog almost doubled within the year to $980 million with organic growth contributing over $244 million or approximately 50% of the 2011 increase.  Commercial backlog represents 29.5% of total backlog versus 16.2% of total backlog in December of 2010.  On an organic basis, total backlog was down 6.2%, or $193 million, with all of the decrease coming in the fourth quarter.

Tony Guzzi, President and Chief Executive Officer of EMCOR Group, commented, “We are pleased with our results for the 2011 fourth quarter and full-year periods, which continued to reflect strong execution in a challenging market environment. During the quarter, we delivered solid organic growth, particularly in our facilities services segment, and profitability continued to meaningfully benefit from the successful completion of several large projects and continued strong performance from our companies that perform industrial work.  We remain steadfast in our commitment to cost control, as SG&A margins for both the three and twelve month periods declined relative to the year ago periods despite the increase in revenues.”

Mr. Guzzi continued, “Over the course of 2011, we undertook a number of actions that further strengthen and diversify our business. We increased our focus on our core operations with the sale of our Canadian business, and also took advantage of opportunities to build on our capabilities with the strategic acquisitions of Bahnson Holdings and USM Services Holdings.  USM significantly enhances our ability to service multi-site customers and has contributed to push the facilities services segment revenues in 2011 to over $2 billion.  While the unusually temperate winter combined with normal integration challenges affected USM’s results, our experience affirms our longer-term view of the market opportunities this acquisition brings to EMCOR.  This has been evidenced by sales successes we have achieved that would not have been possible without the combined efforts of USM and EMCOR.  Furthermore, we expect to fully realize the $5-$6 million in cost synergies originally anticipated as a result of the acquisition.

In addition to our efforts to enhance our strategic position, we also utilized our strong cash flows to return value directly to shareholders through the initiation of the first dividend and major share repurchase programs in the Company’s history.”

Mr. Guzzi concluded, “While I am very pleased with our results, our execution and the steps we have taken to enhance our growth prospects for the long-term, we continue to operate in the trough of the economic cycle and a sustained upturn remains difficult to predict.  Our backlog is solid with an improving mix of attractive commercial and industrial work; however backlog is now entirely composed of projects won during these challenging economic times with margins representative of the competitive pressures from the recession.  Against this backdrop, our focus will be on strong project execution and the successful integration of USM into our business.  EMCOR remains a late cycle company; however we are better positioned from a market sector diversity, cost structure and balance sheet perspective than at any time in our history and both top and bottom line performance will be enhanced substantially by the eventual up cycle in our markets.”

For the 2011 full-year period, net income from continuing operations attributable to EMCOR was $121.7 million, or $1.78 per diluted share. Income from continuing operations included the above-mentioned impairment charge as well as pre-tax transaction expenses related to the acquisition of USM of $4.7 million, or $0.06 per diluted share after-tax.  For the 2010 full-year period, the Company reported a net loss from continuing operations attributable to EMCOR of $85.8 million, or $(1.30) per diluted share. The 2010 net loss included a pre-tax non-cash impairment charge in the 2010 second and third quarters totaling $246.1 million, or $3.25 per diluted share after-tax, as well as a pre-tax gain of $7.9 million, or $0.12 per diluted share after-tax, in the 2010 second quarter from a gain on the sale of the Company’s equity interest in its Middle East Venture.

Excluding 2011’s USM acquisition transaction costs, as well as all of the 2011 and 2010 non-cash impairment charges and the gain on the Middle East sale, non-GAAP net income from continuing operations for the 2011 full-year period was $127.8 million, or $1.87 per diluted share, compared to $124.6 million, or $1.83 per diluted share, for the 2010 full-year period.

Revenues for the 2011 full-year period increased 15.7% to $5.61 billion, compared to $4.85 billion for the 2010 full-year period.  Organic revenue growth for the 2011 full-year period was 7.3%.

Operating income in the 2011 full-year period was $210.8 million, or 3.8% of revenues, compared to an operating loss of $26.5 million, or (0.5%) of revenues, a year ago.  Operating income for the 2011 full-year period included the USM transaction expenses of $4.7 million and the pre-tax non-cash impairment charge of $3.8 million, each discussed above.  Excluding those items, the Company’s non-GAAP operating income for the 2011 full-year period was $219.3 million, or 3.9% of revenues.  For the 2010 full-year period, the Company reported an operating loss of $26.5 million.  Excluding the $246.1 million pre-tax non-cash impairment charge discussed above, the Company’s non-GAAP operating income for 2010 was $219.6 million, or 4.5% of revenues.  The Company recorded restructuring expenses of $1.2 million in the 2011 full-year period and $1.8 million in the 2010 full-year period.

For the 2011 full-year period, SG&A totaled $518.1 million, or 9.2% of revenues, including the $4.7 million in transaction expenses discussed above.  SG&A for the 2010 full-year period was $472.1 million, or 9.7% of revenues.

Net income for the 2011 full-year period was $130.8 million and included $9.1 million of income from discontinued operation.  For the 2010 full-year period, the Company reported a net loss of $86.7 million, which included the above-mentioned non-cash impairment charge and a loss of $0.8 million from discontinued operation.

The Company noted that, based on the current size and mix of its contract backlog and assuming the continuation of current market conditions, it expects to generate revenues in 2012 of approximately $6.0 billion, and diluted earnings per share of $1.65 to $1.95.
