“In 2011, we improved the strength of our business operations, driving increased operating margins, and a 19 percent improvement in earnings per share despite a challenging economic backdrop in a number of our key residential and commercial building end markets,” said Michael W. Lamach, chairman, president and CEO. “We are pleased with the progress we made during this past year. We made notable improvements in pricing capabilities, productivity and working capital management that helped to drive the strong cash flow that supported our share buyback and dividend expansion. We have also taken the necessary actions to improve the performance of the residential HVAC business. Our management team is focused on accelerating restructuring and cost reduction actions to generate sustained profitable growth in what we expect to be a slow growth economy in 2012.”

Additional Highlights for the 2011 Fourth Quarter

Revenues: The company’s reported revenues declined by 5 percent to $3,507 million, compared with revenues of $3,693 million for the 2010 fourth quarter. Total revenues, excluding the recently divested Hussmann business, were up approximately 1 percent, compared with 2010. U.S. revenues, excluding Hussmann, were flat compared to 2010, and revenues from international operations increased approximately 2 percent (up 3 percent excluding currency), as strong growth in Latin America was partially offset by slower activity in Asia.

Operating Income and Margin: Operating income for the 2011 fourth quarter was $339.2 million, an increase of 8 percent compared with $315.2 million for the 2010 fourth quarter. The fourth-quarter operating margin was 9.7 percent (9.5 percent when adjusted for impairment) compared to an operating margin of 8.5 percent for the same period of 2010. Pricing actions and operational excellence initiatives drove the increase in operating profits and margins. These improvements were partially offset by inflation and unfavorable revenue mix.

Fourth-Quarter Business Review

Climate Solutions delivers energy-efficient solutions globally and includes Trane, which provides heating, ventilation and air conditioning (HVAC) systems and building services, parts and controls for commercial buildings, and Thermo King, the leader in transport temperature control solutions. The total results of the recently divested Hussmann refrigeration business are included for the third quarter of 2011 and in all prior periods. The company’s ownership interest in Hussmann was reported using the equity method of accounting for the fourth quarter of 2011 and the same method will be used in all future periods. Fourth-quarter results also included approximately $37 million of revenues and $3 million of operating income for several Hussmann branch operations divested on November 30, 2011.

Revenues for the fourth quarter of 2011 were $1,905 million and declined by 8 percent compared with the fourth quarter of 2010. Excluding Hussmann, revenue increased by 4 percent (up 5 percent excluding currency). Bookings, excluding Hussmann, increased 2 percent year-over-year.

On a year-over-year basis, total commercial HVAC revenues increased slightly, with a 1 percent increase in equipment and systems revenues and flat revenues in parts, services and solutions. Commercial revenues increased in all major overseas markets and declined slightly in North America. Fourth-quarter bookings were down 3 percent compared with the 2010 fourth quarter where equipment bookings were up 21 percent due to orders placed by customers in advance of announced price increases.

Total Thermo King refrigerated transport revenues increased significantly in the fourth quarter compared with last year, due to strong growth in the refrigerated trailer and truck businesses. Seagoing container revenues, auxiliary power units and worldwide aftermarket revenues also increased.

Fourth-quarter segment operating margin of 10.1 percent increased by 3 percentage points compared with last year (excluding Hussmann, operating margin was 10.2 percent). The combination of higher volumes, pricing and productivity actions offset the negative impact of higher commodity costs.

Industrial Technologies provides products, services and solutions to enhance customers’ productivity, energy efficiency and operations. Products include compressed air systems, tools, fluid power products, and golf and utility vehicles. Total revenues in the fourth quarter of $744 million increased approximately 8 percent (up 8 percent excluding currency) compared with the fourth quarter of 2010. Air and Productivity revenues increased 7 percent, with volume increases in all major geographic regions except Asia. Revenues in the Americas increased mid-teens percent compared with 2010. Air and Productivity Solutions revenues outside the Americas increased slightly. Bookings increased 5 percent year-over-year as gains in the Americas and Europe offset slower activity in Asia.

Club Car revenues increased by 9 percent compared with the fourth quarter of 2010, showing gains in golf cars, utility vehicles and aftermarket activity. Bookings increased slightly as golf-related markets continued to show low activity levels.

Fourth-quarter segment operating margin for Industrial Technologies was 15.3 percent, an increase of 2.2 percentage points compared with last year. The segment margin improvement was due to higher volumes, improved pricing and productivity, which were partially offset by inflation, the acceleration of restructuring activity in China and negative foreign exchange.

Residential Solutions includes the Trane and Schlage brands, which deliver safety, comfort and efficiency to homeowners throughout the Americas. Products, services and solutions include mechanical and electronic locks, HVAC systems, indoor air quality solutions and controls, and remote home management systems. Fourth-quarter revenues were $443 million, a decrease of approximately 13 percent (down 13 percent, excluding currency) compared with 2010. Bookings also declined significantly year-over-year.

Total reported residential security revenues were up significantly compared with 2010 as a result of improved sales to the new builder markets and South American customers and higher sales to “big box” customers in the United States from new products.

Residential HVAC revenues declined significantly compared with strong fourth quarter 2010 results which benefitted from significant shipments of high-efficiency HVAC systems before the expiration of tax credits at the end of 2010. Residential revenues and operating profits were also negatively impacted by the growth of R-22 systems, the downward mix shift to lower SEER products and significant planned production reductions taken by the company in the fourth quarter that reduced inventory levels by approximately $90 million.

Fourth-quarter segment operating margin was negative (1.2 percent) compared with 9.4 percent recorded in 2010. The segment margin decline was due to lower volumes, negative mix and inflation, which were partially offset by pricing.

Security Technologies is a leading global supplier of commercial security products and services. The segment’s market-leading products include mechanical and electronic security products, biometric and access-control systems, and security and time and attendance scheduling software. Fourth-quarter revenues of $415 million declined by approximately 3 percent (down 3 percent excluding currency) compared with the fourth quarter of 2010. Fourth-quarter results reflect stagnant commercial building activity in the United States and in Europe. Revenues in the Americas were down slightly as price improvements were more than offset by lower volumes. Revenues in overseas markets also declined. Overall segment bookings were down 5 percent, with slight bookings improvement in the Americas and declines in both Europe and Asia. Fourth-quarter segment operating margin was 19.1 percent, compared with 18.9 percent in the fourth quarter of 2010. The higher segment operating margin was due to higher productivity and improved pricing, which were largely offset by lower volumes and inflation.

Balance Sheet and Share Repurchase

During the fourth quarter, working capital was 1.6 percent of revenues, an improvement of 1.0 percentage point compared with 2010. Available cash flow for the quarter was $332 million and the company generated $944 million of available cash

flow in 2011. Cash balances and total debt balances were $1.2 billion and $3.6 billion, respectively, at the end of the fourth quarter. The company purchased 19 million shares during the fourth quarter and purchased 36 million shares for approximately $1.2 billion during 2011.

Outlook

Ingersoll Rand’s major end markets showed a mixed and slowing demand pattern in the fourth quarter of 2011. There is sustained but moderating activity in the worldwide industrial markets, global parts and service, and across most of the company’s businesses in Asia. Refrigerated transport markets and commercial HVAC replacement activity are expected to demonstrate slower year-over-year growth, especially in Europe where performance is hampered by unstable financial markets. The North American commercial construction market is continuing its weak and uneven demand pattern and activity in North American consumer related markets, especially residential HVAC, is expected to remain depressed for most of 2012.

Revenues for the full year 2012 are expected to be in the range of $14,000 million to $14,400 million. The year-over-year change in currency exchange rates is expected to reduce reported revenue growth by 2 percentage points in 2012. Full-year EPS from continuing operations are expected to be in the range of $2.90 to $3.10. The forecast includes a tax rate of 25 percent for continuing operations and an average diluted share count for the full year of approximately 315 million shares. Available cash flow for full-year 2012 is expected to approximate $1.1 billion, based on projected earnings, capital expenditures and working capital requirements.

First-quarter 2012 revenues are expected to be in the range of $2,975 million to $3,075 million. EPS from continuing operations for the first quarter are expected to be in the range of $0.20 to $0.26. The first quarter earnings forecast includes approximately $50 million of restructuring and cost reduction investments. The first-quarter forecast reflects a tax rate of 25 percent for continuing operations and an average diluted share count of approximately 315 million shares.

The Company reports its financial results in accordance with generally accepted accounting principles in the United States (GAAP). This supplemental schedule provides adjusted non-GAAP financial information and a quantitative reconciliation of the difference between the non-GAAP financial measures and the financial measures calculated and reported in accordance with GAAP.

The non-GAAP financial measures should be considered supplemental to, not a substitute for or superior to, financial measures calculated in accordance with GAAP. They have limitations in that they do not reflect all of the costs associated with the operations of our businesses as determined in accordance with GAAP. In addition, these measures may not be comparable to non-GAAP financial measures reported by other companies.

We believe the non-GAAP financial information provides important supplemental information to both management and investors regarding financial and business trends used in assessing our financial condition and results of operations. We believe that it is meaningful to provide the relative impact of impairment charges and the corresponding tax impacts in order to present a better understanding of our results on a period to period comparative basis.

The non-GAAP financial measures for operating income and margin, tax rate and EPS assist investors with analyzing our business segment results as well as with predicting future performance. In addition, these non-GAAP financial measures are also reviewed by management in order to evaluate the financial performance of each segment. They are the basis for performance reviews, compensation and resource allocation. We believe that the presentation of these non-GAAP financial measures will permit investors to assess the performance of the Company on the same basis as management.

As a result, one should not consider these measures in isolation or as a substitute for our results reported under GAAP. We compensate for these limitations by analyzing results on a GAAP basis as well as a non-GAAP basis, prominently disclosing GAAP results and providing reconciliations from GAAP results to non-GAAP results.
