News Release

EnPro Industries Reports Continued

Strong Results in the Second Quarter of 2011

CHARLOTTE, N.C., August 4, 2011 — EnPro Industries (NYSE: NPO) today reported consolidated net income of $12.2 million, or $0.56 a share, for the second quarter of 2011. These results reflect the deconsolidation of Garlock Sealing Technologies LLC (GST) and its subsidiaries, effective June 5, 2010. (See the note on deconsolidation at the end of this press release.) All per share amounts in this release are stated on a diluted basis.

In the second quarter of 2010, the company reported net income of $45.2 million, or $2.20 a share, including an after-tax gain of $33.8 million, or $1.64 a share, on the deconsolidation of GST.

Before selected items, EnPro’s consolidated net income in the second quarter of 2011 was $16.5 million, or $0.76 share. In the second quarter of 2010, income before selected items was $17.9 million, or $0.87 a share, and included a contribution of $4.7 million or $0.23 a share, from GST prior to June 5. A table listing these selected items and their effect on EnPro’s consolidated earnings in both periods is included in the press release.

Consolidated sales in the second quarter of 2011 were $263.7 million, a 5% improvement over the second quarter of 2010, when sales were $250.8 million and included $33.3 million in third-party sales from GST. Excluding GST’s sales prior to June 5, 2010, third-party sales increased 19% over the second quarter of 2010.

Consolidated earnings before interest, income taxes, depreciation, amortization, asbestos-related expenses and other selected items (EBITDAA) were $39.8 million, or 15.1% of sales, in the second quarter of 2011. In the second quarter of 2010, EBITDAA was $40.7 million, or 16.2% of sales, including a contribution of $8.4 million from GST. Adjusted to exclude GST, EBITDAA margins on third-party sales were 15.0% in the second quarter of 2010.

“Our second quarter results continue the trend of improvement in our markets and our performance,” said Steve Macadam, president and chief executive officer. “Growing demand for many of our products, the contribution of acquisitions and the positive results of our continuous improvement initiatives are all reflected in our performance. Profits and profit margins in our Sealing Products and Engineered Products segments benefited from higher volumes and our efforts to optimize pricing. Although engine shipments declined as expected, our Engine Products and Services segment also reported higher margins as the profitability of the product mix improved.”

Six Months Results

For the first six months of 2011, EnPro’s consolidated net income from continuing operations was $27.4 million, or $1.26 a share. By comparison, consolidated net income from continuing operations in the first six months of 2010 was $50.1 million, or $2.44 a share, and included the after-tax gain of $33.8 million, or $1.64 a share, on the deconsolidation of GST.

Before selected items, EnPro’s consolidated net income in the first half of 2011 was $36.3 million, or $1.67 share. In the first half of 2010, income before selected items was $33.0 million, or $1.60 a share, and included a contribution of $8.7 million, or $0.42 a share, from GST prior to June 5. A table listing these selected items and their effect on EnPro’s consolidated earnings in both periods is included in the press release.

Consolidated sales in the first six months of 2011 were $533.3 million compared to $479.0 million in the first six months of 2010, when GST contributed sales of $77.7 million. Excluding GST from 2010, third-party sales increased by 30% over the first half of 2010.

Consolidated EBITDAA in the first half of 2011 was $82.4 million, or 15.5% of sales. In the first half of 2010, when GST contributed EBITDA of $16.3 million to consolidated results, EBITDA was $77.8 million, or 16.2% of sales. Excluding GST from 2010 results, EBITDAA was 15.4% of sales.

Sealing Products Segment

Sales in the Sealing Product segment improved by $24.2 million, or 20%, over the second quarter of 2010, when GST was included in the segment’s results prior to deconsolidation. Excluding GST from 2010, the segment’s sales improved by 70%, with acquisitions accounting for growth of about 40% and an organic growth rate of about 30%. Sales benefited from increased demand for high performance sealing products from power generation, oil and gas, aerospace and semiconductor markets; higher volumes at Stemco, as activity in heavy-duty truck markets strengthened and as sales to both original equipment manufacturers and the aftermarket increased; and the contribution of acquisitions, which added about $31 million to the segment’s sales in the second quarter.

Profit in the Sealing Products segment improved by 14% over the second quarter of 2010 when GST was included in the segment’s results. However, excluding GST’s contribution in the second quarter of 2010,

2

the segment’s profit improved by nearly 80%, reflecting higher volumes, improved pricing and contributions from acquisitions, primarily Rome Tool & Die and PSI, which were acquired in the first quarter of 2011.

Engineered Products

Sales in the Engineered Products segment improved by 33%. Acquisitions contributed about 15% of the improvement while the balance came from organic growth and favorable foreign exchange, which contributed about equally. Increases in industrial and automotive demand produced higher volumes at GGB Bearing Technology. Compressor Products International (CPI) benefited from acquisitions, which contributed about $11 million to the segment’s sales in the second quarter, and higher activity levels in its refining and petrochemical markets. CPI’s natural gas markets showed modest improvement in the second quarter.

The segment’s profit margin rose to 9.4% of sales and profit improved by 81%. The profit and profit margin benefited from higher volumes, better pricing and increased productivity at GGB. At CPI, profit improved as the business benefited from the contribution of acquisitions, but margins declined slightly on a less attractive sales mix.

Engine Products and Services

As expected, the Engine Products and Services segment shipped no engines in the second quarter of 2011 and sales declined from a year ago, when the segment shipped eight engines and associated equipment. Aftermarket sales were also lower than a year ago. However, the segment’s profit margin increased as the profitability of the product mix improved. The segment also received new engine orders valued at about $60 million in the quarter.

Garlock Sealing Technologies

3

The deconsolidated operations of Garlock Sealing Technologies and its subsidiaries reported a 17% increase in third party sales compared to the second quarter of 2010, when they were included in EnPro’s consolidated results prior to June 5. The increase in sales reflects higher demand from a broad range of markets, including the steel industry and the petrochemical industry in the United States. The profitability of these operations improved as volumes increased and they benefited from better pricing. Measures of GST’s profitability, including adjusted net income, do not reflect expenses of about $4.7 million incurred in connection with the asbestos claims resolution process.

Cash Flows

EnPro’s cash balance stood at $54.7 million at June 30, 2011, a reduction of approximately $165 million from December 31, 2010, when the cash balance was $219.2 million. The balance was reduced primarily by an investment of $155 million in three acquisitions that were completed in the first quarter of 2011. In addition, operating activities provided cash of $12.6 million in the first half of 2011 as volume increases were partially offset by increased working capital needs. In the first half of 2010, operating activities, which included net asbestos cash outflows of $3.8 million and an increase in working capital, used cash of $16.2 million.

GST finished the second quarter with a cash balance of $115.5 million dollars, compared with $87.1 million at the end of 2010.

Outlook

EnPro expects generally stable levels of demand for the remainder of the year from the markets served by its Sealing Products and Engineered Products segments, with the possibility that seasonal factors may reduce activity levels in some markets. These segments will also continue to benefit from acquisitions completed in 2011, which the company expects to contribute sales of about $150 million for the full year. The company’s 2011 outlook for the Engine Products and Services segment is unchanged, with sales about equal to 2010 and all remaining engine shipments scheduled for the third quarter. As a result, that segment’s sales in the third quarter should be substantially higher than in the second quarter.

“We are clearly seeing the benefits of our efforts towards making EnPro a stronger and more versatile company,” said Macadam, “and we look forward to increasing advantages from these efforts as we go through the remainder of the year.”

Deconsolidation of Garlock Sealing Technologies

Results for the second quarter and first six months of 2011 reflect the deconsolidation of Garlock Sealing Technologies LLC (GST) and its subsidiaries, effective June 5, 2010, when GST filed a voluntary petition to begin an asbestos claims resolution process intended to permanently resolve all current and future asbestos claims against it under Section 524(g) of the U.S. Bankruptcy Code. Deconsolidation is required by generally accepted accounting standards, which do not permit the restatement of results of prior periods to reflect the deconsolidation. However, to aid in comparisons of year-over-year data, the company has attached a schedule to this press release showing key operating measures for both EnPro and GST on a pro forma basis. The schedule presents results for the second quarters and full years of 2011 and 2010 as if the deconsolidation of GST had occurred on January 1, 2010.

Non-GAAP Financial Information

This press release contains financial measures that have not been prepared in accordance with GAAP. They include income before asbestos-related expenses and other selected items, EBITDAA, EBITDA and

Management of the Company believes that it would be helpful to the readers of the financial statements to understand the impact of certain selected items on the Company’s reported net income and earnings per share, including items that may recur from time to time. This presentation enables readers to better compare EnPro Industries, Inc. to other diversified industrial manufacturing companies that do not incur significant asbestos-related expenses, the sporadic impact of restructuring activities or other selected items. Management acknowledges that there are many items that impact a company’s reported results and this list is not intended to present all items that may have impacted these results.

The amounts above, which may be considered non-GAAP financial measures, are shown on an after-tax basis and have been calculated by applying a 37.5% assumed effective tax rate to the pre-tax amount . The pre-tax amounts for the asbestos-related expenses and gain on deconsolidation of GST are separately presented in the accompanying consolidated statements. The interest expense with GST is included in interest expense and the restructuring costs and other are included as part of other operating expense. Per share amounts were calculated by dividing by the weighted-average shares of common stock outstanding during the periods.
