IDEX CORPORATION REPORTS THIRD QUARTER 2009 RESULTS;
ADJUSTED EARNINGS PER SHARE OF 39 CENTS;
RECORD FREE CASH FLOW OF $78 MILLION

NORTHBROOK, IL, October 19 — IDEX Corporation (NYSE: IEX) today announced third quarter 2009 results.

New orders in the quarter totaled $339 million, down 4 percent compared to the prior-year period. Sales in the quarter totaled $323 million, 12 percent lower than the prior-year period.

Third quarter 2009 operating income, adjusted for restructuring related charges of $2.8 million, was $49 million and resulted in adjusted operating margin of 15.2 percent, down 290 basis points from prior year (excluding prior year restructuring related charges of $5.3 million and goodwill impairment charges of $30 million). On an as-reported basis, third quarter operating income of $47 million was 51 percent higher than the prior-year period.

Excluding the impact of restructuring related charges, third quarter 2009 adjusted diluted earnings per share was 39 cents, a decrease of 13 cents, or 25 percent, from the third quarter of the previous year (excluding prior year unfavorable impact of restructuring related charges and goodwill impairment charges). On an as-reported basis, diluted earnings per share of 37 cents increased 13 cents, or 54 percent, from the third quarter of the previous year.

Third Quarter 2009 Results

• Orders declined 4 percent compared to the prior year (+7 percent acquisitions, -9 percent organic and -2 percent foreign currency translation).

• Sales declined 12 percent compared to the prior year (+7 percent acquisitions, -17 percent organic and -2 percent foreign currency translation).

• Reported net income was $30 million, or 50 percent higher than the prior year. Adjusted net income of $32 million was $12 million, or 27 percent, lower than the prior year (excluding prior year restructuring and goodwill impairment charges).

• Diluted EPS of 37 cents was 13 cents, or 54 percent, higher than the prior year. Adjusted diluted EPS of 39 cents was 13 cents, or 25 percent, lower than the prior year (excluding prior year impact of restructuring and goodwill impairment charges).

• EBITDA of $62 million was 19 percent of sales and covered interest expense by more than 15 times.

• Free cash flow of $78 million, 15 percent higher than prior year, was an all-time high.

“We achieved solid profit performance and excellent cash flow in the third quarter. Our operating model and flexible cost structure once again illustrates that we can limit the unfavorable margin impact in a down sales environment while continuing to focus on growing market share, demonstrating outstanding responsiveness to changing order patterns and new business opportunities. We continue to generate very strong cash flow, converting 175 percent of net income to free cash thus far in our year-to-date results.

As we look to the fourth quarter, we expect that energy, water, and select health and science end markets will reflect sequential improvement; while the industrial process, retail paint dispensing, and fire suppression end markets will be slightly down sequentially.

Based on current conditions, our projected fourth quarter EPS is in the range of 35 to 37 cents on a fully diluted basis. For the full year, we expect organic revenue to decline approximately 15 percent resulting in adjusted diluted EPS of $1.44 to $1.46.”

Lawrence D. Kingsley
Chairman and Chief Executive Officer

Business Highlights (excluding restructuring related charges)

Fluid & Metering Technologies

• Sales in the third quarter of $157 million reflected an 8 percent decline compared to the third quarter of 2008 (+12 percent acquisitions, -19 percent organic and -1 percent foreign currency translation).

• Operating margin of 16.8 percent represented a 390 basis point decline compared with the third quarter of 2008. Excluding the impact of acquisitions, operating margin was 18.4 percent, a 230 basis point decline compared with the prior-year period due to lower sales.

Health & Science Technologies

• Sales in the third quarter of $76 million reflected an 8 percent decline compared to the third quarter of 2008 (+6 percent acquisitions, -13 percent organic and -1 percent foreign currency translation). The organic decline was primarily due to continued market softness in the non-core HST businesses.

• Operating margin of 20.1 percent reflected a 120 basis point decline compared with the third quarter of 2008. Excluding the impact of the Semrock acquisition, operating margin was 19.7 percent, a 160 basis point decline compared with the prior-year period due to lower sales.

Dispensing Equipment

• Sales of $26 million in the third quarter reflected a 19 percent decline compared with the third quarter of 2008 (-15 percent organic and -4 percent foreign currency translation), as a result of continued deterioration in capital spending for both the North American and European markets.

• Operating margin of 1.2 percent reflected a 180 basis point decline compared with the third quarter of 2008 due to lower volumes in North America and Europe (excluding prior year goodwill impairment charge).

Fire & Safety/Diversified Products

• Sales in the third quarter of $66 million reflected a 19 percent decline compared with the third quarter of 2008 (-16 percent organic and -3 percent foreign currency translation).

• Operating margin of 24.4 percent represented a 90 basis point decline compared with the third quarter of 2008 on lower volumes and unfavorable product mix within the segment.

For the third quarter of 2009, Fluid & Metering Technologies contributed 48 percent of sales and 46 percent of operating income; Health & Science Technologies accounted for 24 percent of sales and 25 percent of operating income; Dispensing Equipment accounted for 8 percent of sales and 1 percent of operating income; and Fire & Safety/Diversified Products represented 20 percent of sales and 28 percent of operating income.

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.
