IDEX CORPORATION REPORTS SECOND QUARTER 2010 RESULTS;
ADJUSTED EARNINGS PER SHARE OF 50 CENTS

NORTHBROOK, IL, July 19 — IDEX Corporation (NYSE: IEX) today announced second quarter 2010 results.

New orders in the quarter totaled $377 million, up 18 percent compared to the prior-year period. Sales in the quarter totaled $379 million, 13 percent higher than the prior-year period.

Second quarter 2010 operating income, adjusted for $1 million of restructuring related charges, was $64 million and resulted in adjusted operating margin of 16.9 percent, up 200 basis points from the prior year (excluding prior year restructuring related charges) due to volume and improved productivity. Adjusted and reported second quarter operating income includes approximately $2 million of acquisition related costs, primarily related to the previously announced Seals Ltd. acquisition.

Excluding the impact from restructuring related charges, second quarter diluted earnings per share was 50 cents, an increase of 13 cents, or 35 percent, from the second quarter of the previous year (excluding prior year restructuring related charges).

Second Quarter 2010 Highlights

• Orders increased 18 percent compared to the prior year (+17 percent organic, +2 percent acquisition and -1 percent for foreign currency translation).

• Sales increased 13 percent compared to the prior year (+11 percent organic, +3 percent acquisition and -1 percent for foreign currency translation).

• Reported net income of $40 million was $12 million, or 45 percent, higher than the prior year. Excluding restructuring related charges, adjusted net income of $41 million was $11 million, or 37 percent, higher than the prior year (excluding prior year restructuring charges).

• Diluted EPS of $0.49 was 15 cents, or 43 percent, higher than the prior year. Excluding restructuring related charges, adjusted diluted EPS of $0.50 was 13 cents, or 35 percent higher than the prior year (excluding prior year restructuring charges).

• EBITDA of $78 million was 21 percent of sales and covered interest expense by more than 21 times.

• Free cash flow of $60 million represents 150% of net income and was 21% higher than the prior year.

“Our second quarter sales results were outstanding. The Health and Science and Fluid and Metering Technology segments outperformed our expectations and, more importantly, continue to outperform the growth rates in the markets we serve. Our Fire and Safety and Dispensing segments continue to perform as planned. These top line results drove strong profitability and this is reflected in a second quarter operating margin of nearly 17 percent, which is 200 basis points higher than the prior year.

Based on current outlook, our projected third quarter 2010 EPS is in the range of 46 to 48 cents on a fully diluted basis. Third quarter estimates exclude approximately $3 million of restructuring related costs associated with the closure of a Health and Science Technologies site in Denmark. Our outlook for the full year 2010 has improved from previous estimates; we expect organic revenue growth in the high single digit range which will result in diluted EPS of $1.85 to $1.90, excluding restructuring related charges.”

Lawrence D. Kingsley
Chairman and Chief Executive Officer

A Note on EBITDA and Free Cash Flow

EBITDA means earnings before interest, income taxes, depreciation and amortization, while free cash flow means cash flow from operating activities less capital expenditures plus the excess tax benefit from stock-based compensation. Management uses these non-GAAP financial measures as internal operating metrics and for enterprise valuation purposes. Management believes these measures are useful as analytical indicators of leverage capacity and debt servicing ability, and uses them to measure financial performance as well as for planning purposes. However, they should not be considered as alternatives to net income, cash flow from operating activities or any other items calculated in accordance with U.S. GAAP, or as an indicator of operating performance. The definitions of EBITDA and free cash flow used here may differ from those used by other companies.
