“We are pleased with our overall performance for the first quarter of 2008. Growth in the Fluid and Metering Technologies segment was driven by strong global demand in the process control and infrastructure-related end markets. In the Health and Science Technologies segment, we realized strong growth in the core health and science end markets. Within the Dispensing Equipment segment, timing of orders unfavorably impacted first quarter revenue. Despite softness in our fire suppression business, our engineered band clamping and rescue tools businesses performed well within the Fire & Safety/Diversified Products segment.

For the second quarter of 2008, we expect solid performance in the Fluid and Metering Technologies segment as a result of continued strong global investment in the infrastructure-related markets and process control industries. Within the Health and Science Technologies segment, growth will be driven by strength in the core analytical instrumentation, IVD and biotechnology markets. Growth in the Dispensing Equipment segment will be driven by continued paint channel expansion in global markets and anticipated program orders in the large U.S. retail markets. We expect our Fire & Safety/Diversified Products segment to perform well, driven by strong demand for band clamping applications and global expansion of our rescue tools business, partially offset by continued weakness in the North American fire suppression market.

Given these trends and current market conditions, we reaffirm our expected full year 2008 total revenue growth in the range of 13 to 15 percent and EPS in the range of $2.10 to $2.18 compared to $1.90 in the prior year. In addition, 2008 free cash flow is projected to exceed net income by 10 to 20 percent. For the second quarter of 2008, we project total revenue growth in the range of 14 to 16 percent and EPS in the range of 53 to 56 cents per diluted share.

Overall, we are pleased with our first quarter 2008 results and we anticipate continued strong performance in 2008.”

Chairman and Chief Executive Officer

Business Highlights
Fluid & Metering Technologies

o Sales in the first quarter of $170.9 million reflected 25 percent growth (17 percent acquisitions, 5 percent organic and 3 percent foreign currency translation). Growth was driven by continued global demand for infrastructure-related applications and acquisition performance.

o Operating margin of 20.0 percent represented a 180 basis point decline compared with the first quarter of 2007 primarily driven by the impact of recent acquisitions.

Health & Science Technologies

o Sales in the first quarter of $83.6 million reflected 4 percent growth (4 percent acquisitions, -2 percent organic and 2 percent foreign currency translation). Strong growth in core analytical instrumentation, IVD and biotechnology markets coupled with acquisitions was partially offset by slow growth in specific pneumatic OEM markets.

o Operating margin of 18.0 percent represented an 80 basis point improvement compared with the first quarter of 2007, primarily driven by favorable mix.

Dispensing Equipment

o Sales of $50.0 million in the first quarter reflected 4 percent growth compared with the first quarter of 2007 (-6 percent organic and 10 percent foreign currency translation). Growth was unfavorably impacted by order timing.

o Operating margin of 22.5 percent represented a 190 basis point decline compared with the first quarter of 2007, driven by lower volume.

Fire & Safety/Diversified Products

o Sales in the first quarter of $68.7 million were essentially flat versus the prior year (-4 percent organic and 4 percent foreign currency translation). The engineered band clamping business as well as the rescue business achieved strong growth, offset by weak demand in the North American fire suppression market.

o Operating margin of 25.8 percent represented a 360 basis point increase compared with the first quarter of 2007, as a result of favorable mix.

For the first quarter of 2008, Fluid & Metering Technologies contributed 46 percent of sales and 44 percent operating income; Health & Science Technologies accounted for 23 percent of sales and 19 percent of operating income; Dispensing Equipment accounted for 13 percent of sales and 14 percent of operating income; and Fire & Safety/Diversified Products represented 18 percent of sales and 23 percent of operating income.

Bank Term Loan

On April 18, 2008, IDEX Corporation closed a $100 million senior bank term loan with consistent covenants and expiration of the existing revolving credit facility. The term loan was timed to capitalize on current, favorable market conditions and will be used to fund the company’s ongoing capital deployment strategy which is primarily focused on acquisitive growth.

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.
