FOR IMMEDIATE RELEASE

GARDNER DENVER REPORTS SECOND QUARTER 2012 RESULTS

WAYNE, Pa., July 19, 2012 — Gardner Denver, Inc. (NYSE: GDI) today reported second quarter 2012 net income of $75.3 million, or $1.51 per diluted share, compared to $67.1 million, or $1.27 per diluted share in the second quarter of 2011. Results for the second quarter of 2012 included unfavorable after-tax charges of $0.02 diluted earnings per share primarily related to the Company’s disposition of two facilities and acquisition related costs, resulting in Adjusted DEPS of $1.53. ⁽¹⁾

Second quarter 2012 revenues were $613.0 million, an increase of 0.4% compared to the prior year second quarter. The positive contribution from the recent Robuschi acquisition as well as increased sales of pressure pumps and associated after markets parts, and late cycle projects in the Engineered Products Group (“EPG”) were offset by headwind from foreign exchange, as the U.S. Dollar appreciated against other major currencies, as well as declines in the Industrial Products Group (“IPG”) primarily in Europe.

Operating income for the second quarter of 2012 was $108.0 million, compared to $99.2 million in the second quarter of the prior year, resulting in an increase in operating margins of 140 basis points to 17.6%. Operating margins expanded in both segments driven by tight cost controls and the impact of the recent Robuschi acquisition.

“In a slower growth environment, Gardner Denver had a good second quarter as DEPS increased 19% over the prior year to $1.51, exceeding our previously stated guidance,” said Michael M. Larsen, Gardner Denver’s interim Chief Executive Officer. “We executed well on our margin expansion initiatives as operating margins expanded in both segments and we continued to take steps toward optimizing our cost structure, as we announced the closure of 8 facilities globally and reduced staffing by 3%. Our cash flow from operating activities was $66 million, an increase of 36% compared to the first quarter of 2012, and we returned over $107 million in cash to our shareholders in the second quarter through the repurchase of 1.664 million shares of our common stock and the payment of dividends.”

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

Engineered Products Group (EPG)

EPG revenues increased 0.2% to $283 million for the second quarter of 2012 compared to the prior year second quarter principally as a result of higher unit volumes in pressure pumps and associated aftermarket parts offset by declines in the shorter cycle Thomas business. Operating income in the second quarter of 2012 increased 4% to $67.2 million as operating margins improved to 23.7%, up 80 basis points from last year’s second quarter.

“Second quarter shipments of OEM pressure pumps and fluid ends increased at a double-digit rate versus the same period in the prior year. As expected, EPG orders declined 36% driven by significantly lower demand for Petroleum and Industrial Pumps partially offset by orders for Nash pumps as a result of strength in chemical and oil & gas end markets. In our Petroleum and Industrial Pumps business we continue to focus on capturing the aftermarket opportunity and taking decisive cost actions to partially offset the impact of the expected decline in shipments in the second half of 2012,” said Larsen.

Industrial Products Group (IPG)

IPG revenues increased 0.6% to $330 million for the second quarter of 2012 compared to the prior year second quarter driven primarily by the positive contribution from the recent Robuschi acquisition and strong demand in the Asia Pacific region, offset by lower sales principally in Europe and China as well as headwind from foreign exchange. Operating income in the second quarter of 2012 increased 19% to $40.8 million as operating margins expanded to 12.4%, up 190 basis points from last year’s second quarter.

“IPG had a solid second quarter as the team delivered on our ‘14 x 14’ margin expansion strategy in a slower growth environment, and we were very pleased with the operational and financial performance of our recent Robuschi acquisition. In addition, we continue to take the necessary steps to optimize our cost structure in a more challenging environment as the development of our European restructuring plans is nearing completion,” said Larsen.

Outlook

“Halfway through 2012 we are pleased with our operational and financial performance as revenues in the first six months of 2012 increased 7% and Adjusted DEPS increased 17% over the same period in 2011. ⁽¹⁾ Looking forward to the balance of 2012, we face headwinds from a more challenging macroeconomic environment, principally in Europe, lower shipments of OEM pressure pumps in line with previous expectations and foreign exchange. We remain fully committed to our strategic initiatives, supported by the lean principles of the Gardner Denver Way, as we continue to

2

execute on our plans for margin expansion and cash generation. Our capital deployment strategy of opportunistically repurchasing our stock remains unchanged and we currently have a 1.6 million share repurchase authorization from our Board of Directors,” said Larsen.

The company now expects full-year DEPS to be in the range of $4.90 to $5.10 as compared to its prior guidance of $5.20 to $5.40. This new forecast represents a $0.30 adjustment driven principally by a broadly weaker economy in Europe and the exchange rate impact of foreign currencies. Third quarter 2012 earnings are expected to be in the range of $1.12 to $1.22 DEPS. These projections include profit improvement costs and other items totaling $0.03 per diluted share for the third quarter and $0.40 per diluted share for the total year. Third quarter 2012 Adjusted DEPS are expected to be in a range of $1.15 to $1.25 and full year 2012 Adjusted DEPS are expected to be in a range of $5.30 to $5.50, as compared to prior guidance of $5.60 to $5.80. ⁽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.
