WAYNE, Pa., February 22, 2013 — Gardner Denver, Inc. (NYSE: GDI) today reported fourth quarter and full year 2012 results that included record Adjusted DEPS. ⁽¹⁾

Revenues for the fourth quarter ended December 31, 2012 were $589.7 million, down 4% compared with the prior year fourth quarter. Operating income for the fourth quarter of 2012 was $95.9 million, compared with $108.1 million in the fourth quarter of the prior year, resulting in an operating margin decline of 130 basis points to 16.3%. Net income attributable to Gardner Denver for the fourth quarter of 2012 was $69.1 million, or $1.40 DEPS, compared with $77.4 million, or $1.52 DEPS, in the same period of 2011. Results for the fourth quarter of 2012 included after-tax charges of $0.09 per diluted share primarily related to the Company’s ongoing restructuring activities, severance related costs and costs incurred in connection with the exploration of strategic alternatives. Excluding these charges, Adjusted DEPS for the fourth quarter of 2012 was $1.49, compared with $1.54 in the same period of 2011. ⁽¹⁾ 

For the full year ended December 31, 2012, revenues were $2.356 billion compared with $2.371 billion in the same period of 2011. Adjusted Operating Income declined slightly to $404.3 million, compared with $414.3 million earned in the same period of 2011. ⁽¹⁾ DEPS was $5.28 for 2012 and Adjusted DEPS reached a record high of $5.74, up from $5.51 per diluted share in 2011. ⁽¹⁾ 

“During 2012, we successfully executed our strategy in the midst of a challenging economic environment and as a result we achieved record Adjusted DEPS for 2012 as well as strong cash flow from operations of $289 million,” said Michael M. Larsen, Gardner Denver’s President and Chief Executive Officer. “We took decisive actions to improve productivity and reduce structural costs and we were pleased with our strong finish for 2012 that positions us well for 2013 performance.”

Factors affecting fourth quarter results for the Company’s business segments included: ⁽²⁾

Engineered Products Group (EPG)

In the fourth quarter of 2012, EPG revenues decreased 10% to $263.3 million compared with the same period of 2011. On a sequential basis, Gardner Denver grew revenues by 11% in the fourth quarter of 2012 compared with $236.7 million in the third quarter of 2012. Operating income in the fourth quarter of 2012 decreased 20% to $57.2 million and as a result operating margins decreased to 21.7%, down 280 basis points from last year’s fourth quarter.

For the full year 2012, EPG revenues decreased 5% to $1.062 billion from $1.115 billion in the same period of 2011. Adjusted Operating Income for the full year 2012 was $244.6 million, a decrease of 8% versus prior year, and Adjusted Operating Margins decreased 70 basis points to 23.0%. ⁽¹⁾ As expected, EPG Adjusted Operating Income in the fourth quarter decreased and Adjusted Operating Margins fell due to lower revenues in our Petroleum and Industrial Pump business.

Industrial Products Group (IPG)

IPG revenues increased 1% to $326.4 million for the fourth quarter of 2012 compared to the same period of 2011. Operating income in the fourth quarter of 2012 increased 5% to $38.7 million and Adjusted Operating Margins increased to 12.9%, up 130 basis points from the same period of 2011. ⁽¹⁾

For the full year 2012, IPG revenues increased 3% to $1.294 billion from $1.256 billion for the full year of 2011, driven largely by the Robuschi acquisition. Adjusted Operating Income for the full year 2012 was $159.7 million, an increase of 7% versus prior year, and Adjusted Operating Margins increased to 12.3%, up 40 basis points from the same period of 2011. ⁽¹⁾

“Our IPG group executed well on our margin expansion initiatives supported by the principles of the Gardner Denver Way,” said Mr. Larsen. “We are implementing decisive cost control actions, such as our previously announced European restructuring plan, and will continue to opportunistically right-size and restructure our operations as needed. We will also continue to execute our strategy with a distinct focus on expanding our sales presence and capturing the aftermarket opportunity, which we believe will help us to mitigate the challenging environment for Petroleum and Industrial Pumps. We believe these actions position Gardner Denver to achieve continued margin expansion and long-term profitable growth,” said Mr. Larsen.

Outlook

“We remain focused on executing our proven strategy that has allowed Gardner Denver to achieve sustainable, profitable growth over the past 4 years,” said Mr. Larsen. “Our dynamic plan reflects the current macroeconomic challenges as well

as our commitment to driving growth and value for our shareholders. We are confident that Gardner Denver is taking the steps necessary to position the Company to capitalize on favorable long-term industry trends, including recovery in the global markets, particularly energy. In the near-term, we are encouraged by recent improvements in economic indicators and order rates, and we believe the Company is poised to benefit from improving trends should they occur faster than expected. At the same time, we believe we are being appropriately cautious in our 2013 outlook.”

Earnings for the full year of 2013 are expected to be in the range of $4.25 to $4.50 per diluted share. First quarter 2013 DEPS are expected to range between $0.90 and $1.00. These projections include profit improvement costs and other items totaling $0.04 per diluted share for the first quarter and $0.75 per diluted share for the full year 2013. Based upon this, first quarter 2013 Adjusted DEPS are expected to range between $0.94 and $1.04 and full year 2013 Adjusted DEPS are expected to range between $5.00 and $5.25. ⁽¹⁾

While Gardner Denver, Inc. reports financial results in accordance with accounting principles generally accepted in the U.S. (“GAAP”), this press release includes non-GAAP measures. These non-GAAP measures are not in accordance with, nor are they a substitute for, GAAP measures. Gardner Denver, Inc. believes the non-GAAP financial measures of Adjusted Operating Income and Adjusted DEPS provide important supplemental information to both management and investors regarding financial and business trends used in assessing its results of operations. Gardner Denver believes excluding the specified items from operating income and DEPS provides management a more meaningful comparison to the corresponding reported periods and internal budgets and forecasts, assists investors in performing analysis that is consistent with financial models developed by investors and research analysts, provides management with a more relevant measurement of operating performance, and is more useful in assessing management performance.
