RAISES FULL YEAR EPS GUIDANCE

LAKE FOREST, IL, OCTOBER 16 - IDEX Corporation (NYSE: IEX) today announced its financial results for the three month period ended September 30, 2017.

Third Quarter 2017 Highlights

• Orders were up 8 percent overall and 7 percent organically

• Sales were up 8 percent overall and 7 percent organically

• Operating margin was 22.0 percent

• EPS was $1.08, up 17 cents, or 19 percent

Third Quarter 2017

Orders of $573.8 million were up 8 percent (+7 percent organic and +1 percent foreign currency translation) compared with the prior year period.

Sales of $574.5 million were up 8 percent (+7 percent organic and +1 percent foreign currency translation) compared with the prior year period.

Gross margin of 44.9 percent was up 140 basis points from the prior year period. Excluding $4.6 million of pre-tax fair value inventory step-up charges from the prior year period, gross margin would have been up 50 basis points primarily due to volume leverage.

Operating income of $126.5 million resulted in an operating margin of 22.0 percent, up 130 basis points from the prior year operating margin and 90 basis points from the prior year adjusted operating margin. Excluding the $4.6 million fair value step-up charges from the prior year results, operating margin would have been up 10 basis points. Operating income drove EBITDA of $146.1 million which was 25 percent of sales and covered interest expense by more than 13 times.

Net income was $83.8 million which resulted in EPS of $1.08, up 17 cents, or 19 percent, from the prior year period. Excluding the net loss on divestitures from the prior year period, EPS was up 16 cents, or 17 percent from adjusted prior year EPS.

Cash from operations for the third quarter of $124.0 million led to free cash flow of $115.5 million, which converted at 138 percent of net income.

The Company repurchased 116 thousand shares of common stock for $13.8 million in the third quarter of 2017.

“Solid execution, coupled with increasing demand, delivered another strong quarter for IDEX. Third quarter organic orders and sales both grew 7 percent, which drove operating margin of 22.0 percent. HST and FMT continued to lead the way with 10 percent and 7 percent organic revenue growth, respectively. This growth resulted in EPS of $1.08 which was up 16 cents, or 17 percent, from the adjusted prior year period. Free cash flow was very strong with a conversion rate at 138 percent of net income.
I am pleased with the solid organic growth rates we have achieved this year. Consistent with our capital deployment strategy, our number one priority is to fully fund long-term organic growth opportunities. Our commitment to segmenting our businesses and funding our best organic initiatives is helping to deliver on our goal of outperforming our underlying markets. Looking ahead, we will continue to fund these opportunities as an integral part of our capital deployment objectives which include pursuing strategic M&A, funding our dividend and being opportunistic in repurchasing our shares.
Based on our third quarter results and strength in orders across all three segments, we are raising full year 2017 adjusted EPS guidance to $4.25 to $4.27, with fourth quarter EPS of $1.06 to $1.08. We also reaffirm full year 2017 organic revenue growth of 5 percent, with 6 percent organic growth expected in the fourth quarter.”

Non-U.S. GAAP Measures of Financial Performance

The Company supplements certain U.S. GAAP financial performance metrics with non-U.S. GAAP financial performance metrics in order to provide investors with better insight and increased transparency while also allowing for a more comprehensive understanding of the financial information used by management in its decision making. Reconciliations of non-U.S. GAAP financial performance metrics to their most comparable U.S. GAAP financial performance metrics are defined and presented below and should not be considered a substitute for, nor superior to, the financial data prepared in accordance with U.S. GAAP. There were no adjustments to U.S. GAAP financial performance metrics other than the items noted below.

• Organic orders and sales are calculated according to U.S. GAAP excluding amounts from acquired or divested businesses during the first twelve months of ownership or divestiture and the impact of foreign currency translation.

• Adjusted operating income is calculated as operating income plus restructuring expenses plus or minus the net loss or gain on sale of businesses.

• Adjusted operating margin is calculated as adjusted operating income divided by net sales.

• Adjusted net income is calculated as net income plus restructuring expenses plus or minus the net loss or gain on sale of businesses, net of the statutory tax expense or benefit.

• EBITDA is calculated as net income plus interest expense plus provision for income taxes plus depreciation and amortization. We reconciled EBITDA to net income on a consolidated basis as we do not allocate consolidated interest expense or consolidated provision for income taxes to our segments.

• Adjusted EBITDA is calculated as EBITDA plus restructuring expenses plus or minus the net loss or gain on sale of businesses.

• Free cash flow is calculated as cash flow from operating activities less capital expenditures.
