LAKE FOREST, Ill.– IDEX Corporation (NYSE: IEX) today announced its financial results for the three month period ended March 31, 2013.

Sales in the quarter totaled $494 million, 1 percent higher than the prior year period and down 1 percent on an organic basis.

First quarter 2013 operating income was $95 million. This resulted in an operating margin of 19.2 percent, up 90 basis points from the prior year adjusted operating margin, primarily due to productivity and benefits from our structural cost actions taken in prior years.

First quarter earnings per share were 74 cents, an increase of 8 cents, or 12 percent, from the adjusted prior year.

Free cash flow was $67 million for the quarter, a 28 percent increase from prior year first quarter due to higher earnings.

First Quarter Highlights

Orders of $515 million decreased 3 percent compared to the prior year (-5 percent organic and +2 percent acquisition).

Sales of $494 million increased 1 percent compared to the prior year (-1 percent organic and +2 percent acquisition).

Operating margin of 19.2 percent was up 90 basis points from the adjusted prior year.

Net income of $61 million represents an increase of 10 percent compared to the prior year adjusted net income of $56 million.

EPS of 74 cents was 8 cents, or 12 percent, higher than the prior year adjusted EPS of 66 cents.

EBITDA of $116 million, which represents an 11 percent increase from the prior year, was 23 percent of sales and covered interest expense by 11 times.

Free cash flow of $67 million, which represents a 28 percent increase from the prior year, was over 109 percent of net income.

The Company completed the repurchase of 673 thousand shares of common stock for $34 million in the first quarter of 2013.

The Company acquired FTL Seals Technology.

The Board of Directors approved a 15 percent increase in the quarterly cash dividend in April.

“Excellent operating income growth, margin improvement and cash generation marked IDEX’s first quarter of 2013. As anticipated, orders proved a tough year-over-year comparison due to the large dispensing replenishment project in 2012. Orders decreased 3 percent year-over-year, but were up 7 percent sequentially, and we built over $20 million of backlog during the quarter. I am pleased with our ability to execute and deliver a 90 basis point improvement in operating margin and a 12 percent increase in EPS. The expected benefits from the recently completed restructuring and structural cost actions are being realized in our financials.

Previously I highlighted our team’s focus on executing a disciplined capital deployment plan of strategic acquisitions, shareholder dividends and share repurchases. In March, we successfully completed the acquisition of FTL Seals Technology (“FTL”). FTL is a leader in specialty seals and bearings, and will operate alongside Precision Polymer Engineering to expand our capabilities in proprietary sealing solutions. We are excited to have FTL join the IDEX portfolio. The IDEX Board of Directors also approved a 15 percent increase to the quarterly shareholder dividend, now 23 cents. We continued to execute our share repurchase program throughout the first quarter and expect it to continue throughout 2013.

On a regional basis, North America is improving, Europe remains soft and Asia is uneven. Despite this difficult organic growth environment, we are confident we can continue to generate strong operating margins and cash flows. We project second quarter 2013 EPS to be in the range of 73 to 75 cents, while maintaining our full year 2013 EPS guidance of $2.85 to $2.95, based on low- to mid-single digit organic revenue growth.”

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.
