News Release

EnPro Industries Reports Results for the

First Quarter of 2012

CHARLOTTE, N.C., May 3, 2012 — EnPro Industries (NYSE: NPO) today reported consolidated net income of $13.8 million, or $0.64 a share, for the first quarter of 2012. These results compare to consolidated net income of $15.2 million or $0.71 a share, in the first quarter of 2011.

Before selected items, including interest due to Garlock Sealing Technologies LLC (GST), a deconsolidated subsidiary, and restructuring costs associated with the integration of acquisitions, income in the first quarter of 2012 was $19.5 million, or $0.91 a share. In the first quarter of 2011, income before selected items was $19.7 million or $0.92 a share. The results of GST and its subsidiaries were deconsolidated effective June 5, 2010, when GST entered a process to reach a permanent resolution of all current and future asbestos claims. A table on page 10 of this press release shows the effect of selected items, including interest due to GST and restructuring costs, in the first quarters of 2012 and 2011.

All per share amounts are stated on a diluted basis.

Sales in the first quarter of 2012 were $311.5 million, a 16% increase over the first quarter of 2011, when sales were $269.6 million. Acquisitions completed in 2011 contributed about 12 points, or $31.5 million, of the increase over the first quarter of 2011, while the effectiveness of the company’s operating strategies and continued improvements in its markets, especially in the Sealing Products segment, contributed about 5 points of the increase. Foreign exchange was slightly unfavorable in the quarter.

Consolidated earnings before interest, income taxes, depreciation and amortization and other selected items (EBITDA) were $46.5 million in the first quarter of 2012, a 9% improvement over the first quarter of 2011, when EBITDA was $42.6 million.

“Our performance in the first quarter of 2012 is an encouraging start to the new year,” said Steve Macadam, president and chief executive officer. “Despite high demand in the first quarter of 2011 as several of our businesses benefitted from restocking by their customers, our first quarter 2012 sales showed healthy year-over-year growth in many of our markets. We saw benefits from our enterprise excellence programs as we intensify our sales efforts in order to gain market share and introduce new products. In addition, acquisitions that we completed in 2011 contributed to both sales and profits in the quarter. We are confident in the effectiveness of our strategy and performance improvement program, and we expect them to continue to benefit our results throughout the year.”

Sealing Products Segment

Acquisitions, the benefit of the company’s enterprise excellence programs and strengthening markets combined to increase sales in the Sealing Products segment by 29%, or $33.8 million, over the first quarter of 2011. Acquisitions completed in 2011 added sales of $25.2 million, an increase of about 20%. Organic factors contributed growth of 9% as the segment benefited from demand in nuclear power, semiconductor and upstream oil and gas markets, as well as from original equipment manufacturers in the heavy-duty truck industry.

The segment’s profits improved to $22.5 million in the first quarter of 2012, a 15% increase over the first quarter of 2011. Segment profits included a restructuring charge of $0.4 million and an increase of $1.1 million in amortization expenses compared to the first quarter of 2011 and were also affected by investments to improve efficiencies and support the growth of businesses in the segment. Within the segment, profits improved in the consolidated operations of the Garlock family of companies, despite ongoing integration costs associated with the PSI acquisition, including the closure of a facility in Houston and the transfer of manufacturing to the Pikotek facility near Denver. The Technetics Group also reported a stronger quarter, reflecting the benefit of the Tara acquisition and volume increases from its semiconductor and energy markets. Profits declined at Stemco as the business recorded higher sales of original equipment products and of braking products, which tend to have lower margins than Stemco’s core aftermarket products, and costs associated with facility improvements at Rome Tool and Die, which was acquired in the first quarter of 2011.

Segment profit margins were 15.1% in the first quarter of 2012 compared to 16.9% in the first quarter of 2011. The decrease primarily reflects the performance of Stemco, increased sales of lower margin products in the Technetics Group as a result of the acquisition of Tara Technologies in the third quarter of 2011, and high margin nuclear sales in the first quarter of 2011.

Engineered Products Segment

In the first quarter of 2012, the Engineered Products segment reported an increase in sales of $6.3 million, or 7%, compared to the first quarter of 2011. Sales benefited from organic growth of about 2%, primarily reflecting

2

increased demand from petro-chemical markets in the United States. Acquisitions completed in 2011 increased sales by 7%, or $6.3 million. The effect of unfavorable foreign exchange reduced sales by about 2%, partially offsetting the benefits of organic growth and acquisitions.

The segment’s profits declined by $1.1 million, or 11%, in the first quarter of 2012 compared to the first quarter of 2011. Within the segment, profits improved at GGB Bearing Technology as it benefited from favorable pricing, lower raw material costs and improved efficiencies. However, profits at Compressor Products International decreased as CPI recognized restructuring costs associated with the acquisition of the Mid Western Companies. CPI also experienced softness in its European markets and the temporary effects of moving production into a new facility in Germany. Acquisition related costs in the quarter included restructuring expense of $0.9 million and increased amortization costs of $0.3 million.

Segment profit margins declined to 8.9% in the first quarter of 2012 from 10.7% in the first quarter of 2011.

Engine Products and Services Segment

In the Engine Products and Services segment, Fairbanks Morse Engine shipped fewer engines in the first quarter of 2012 than in the first quarter of 2011, but the use of percentage of completion accounting in the segment and increased aftermarket activity resulted in slightly higher sales. The segment began using percentage of completion accounting for engine programs in the third quarter of 2011. Lower costs and a favorable product mix led to a slight increase in segment profits and profit margins.

Garlock Sealing Technologies

Third party sales at GST and its subsidiaries increased by 10% over the first quarter of 2011. Among the factors benefitting GST’s sales were higher volumes in North American industrial markets and better pricing. Price increases contributed to improved operating profits at GST and profit margins were about the same as in the first quarter of 2011.

Measures of GST’s profitability, including adjusted net income, do not reflect expenses incurred in connection with the asbestos claims resolution process. Those expenses were $4.2 million in the first quarter of 2012 compared to $4.3 million in the first quarter of 2011.

Cash Flows

EnPro’s cash balance stood at $39.4 million at March 31, 2012, an increase of approximately $9 million from December 31, 2011. Operating activities provided cash of $3.0 million in the first quarter of 2012, despite an increase in working capital of about $35 million as sales improved. In the first quarter of 2011, operations used cash of $12.8 million, reflecting higher working capital and income tax payments.

After the close of the first quarter, EnPro completed the acquisition of Motorwheel Commercial Vehicle Systems in a cash transaction which was funded by borrowings of approximately $85 million from the company’s revolving credit facility. After funding the acquisition, borrowing availability under the facility was approximately $30 million. For the remainder of the year, the company believes operating cash flows will be sufficient to fund working capital and capital expenditures and to repay a substantial amount of borrowings against the credit facility.

GST finished the first quarter of 2012 with a cash balance of $119.8 million dollars, compared with $126.3 million at the end of 2011.

Outlook

“Our first quarter results have laid the foundation for improved performance in 2012,” said Macadam. “We are effectively executing our enterprise excellence programs, and we expect to see growing benefits from them as we focus on the successful integration of our acquisitions. These initiatives, combined with stable markets, should continue to benefit us for the remainder of the year.”

Macadam said the company currently expects 2012 sales to increase by more than 12% over 2011, including the benefit of the recent Motorwheel acquisition. The company outlook for full year sales anticipates stable organic growth with typical seasonal patterns and a contribution from acquisitions of between $55 and $60 million over the final three quarters of 2012. The contribution from acquisitions includes Motorwheel and those completed in the last nine months of 2011.

Macadam said the company also continues to expect total segment profit margins for the full year of 2012 to improve over those reported in 2011, although expenses related to acquisitions should continue to affect year-over-year comparisons.
