NORTHBROOK, IL, February 3 — IDEX Corporation (NYSE: IEX) today announced its financial results for the three- and twelve-month periods ended December 31, 2009.

New orders in the quarter totaled $348 million, up 4 percent compared to the prior-year period. Sales in the quarter totaled $343 million, 3 percent lower than the prior-year period. Both orders and sales were favorably impacted by 3 percent foreign currency translation and 1 percent acquisitions.

Fourth quarter 2009 operating income, adjusted for restructuring related charges of $3.8 million, was $56 million and resulted in adjusted operating margin of 16.4 percent, up 220 basis points from the prior year (excluding prior year restructuring related charges of $12.7 million). On an as-reported basis, fourth quarter operating income of $52 million was 39 percent higher than the prior-year period.

Excluding the impact of restructuring related charges, fourth quarter adjusted diluted earnings per share was 43 cents, an increase of 5 cents, or 13 percent, from the fourth quarter of the previous year (excluding prior year unfavorable impact of restructuring related charges). On an as-reported basis, diluted earnings per share of 40 cents increased 13 cents, or 48 percent, from the fourth quarter of the previous year.

Full Year 2009 Highlights

• Orders decreased 10 percent compared to the prior year (+5 percent acquisitions, -13 percent organic and -2 percent foreign currency translation).

• Sales decreased 11 percent compared to the prior year (+5 percent acquisitions, -14 percent organic and -2 percent foreign currency translation).

• Reported net income of $113 million was $14 million, or 11 percent, lower than the prior year. Excluding restructuring related charges and the acquisition related inventory fair value expense, adjusted net income of $124 million was $35 million, or 22 percent, lower than the prior year (excluding prior year restructuring and goodwill impairment charges).

• Diluted EPS of $1.40 was 13 cents, or 8 percent, lower than the prior year. Excluding restructuring related charges and the acquisition related inventory fair value expense, adjusted diluted EPS of $1.53 was 39 cents, or 20 percent, lower than the prior year (excluding prior year restructuring and goodwill impairment charges).

• EBITDA of $242 million was 18 percent of sales and covered interest expense by more than 14 times.

• Free cash flow of $190 million represented 168 percent of net income.

“While 2009 proved to be a challenging year, we are seeing signs of recovery in the global economy and stabilization in most of our end markets. In the fourth quarter, we achieved strong sequential revenue growth and, while revenue is not yet back to prior year levels, we have seen improved order activity across all segments. Our restructuring efforts are nearly complete. We are realizing significant operating margin improvement. Overall, we are very pleased with our performance in the fourth quarter.

Looking ahead to 2010, we are well positioned to deliver top-line growth across most of the markets we serve. Our current outlook projects strong growth from our energy, water and health & science end markets, partially offset by weakness in the fire suppression and dispensing end markets. We will continue to leverage our cost structure and focus on commercial excellence and operational execution while we invest in global markets that will enable long-term sustainable growth.

Based on current outlook, our projected first quarter 2010 EPS is in the range of 40 to 42 cents on a fully diluted basis. For the full year 2010, we expect organic revenue growth of approximately 2 - 4 percent resulting in diluted EPS of $1.63 to $1.73. Organic growth higher than 4 percent will be dependent on the extent and sustainability of second half 2010 economic recovery.”

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.
