Third quarter 2010 operating income, adjusted for $4 million of restructuring related charges, was $66 million and resulted in adjusted operating margin of 17.6 percent, up 240 basis points from the prior year (excluding prior year restructuring related charges) due to volume and improved productivity.

Excluding the impact from restructuring related charges, third quarter adjusted diluted earnings per share was 50 cents, an increase of 11 cents, or 28 percent, from the third quarter of the previous year (excluding prior year restructuring related charges).

Third Quarter 2010 Highlights

• Orders increased 13 percent compared to the prior year (+11 percent organic, +4 percent acquisition and -2 percent for foreign currency translation).

• Sales increased 16 percent compared to the prior year (+14 percent organic, +4 percent acquisition and -2 percent for foreign currency translation).

• Reported net income of $39 million was $9 million, or 30 percent, higher than the prior year. Excluding restructuring related charges, adjusted net income of $41 million was $9 million, or 29 percent, higher than the prior year (excluding prior year restructuring charges).

• EBITDA of $77 million was 21 percent of sales and covered interest expense by more than 18 times.

• Free cash flow of $54 million represents 140% of net income.

“Our third quarter results were better than expected, driven by broad based demand. International markets continue to fuel strong organic performance and we are experiencing solid domestic sales as well. We are investing in people and new product to drive growth in 2011 and beyond.

Third quarter operating margin was up 240 basis points as a result of operating leverage on fixed cost improvement achieved over the past two years and ongoing operational excellence initiatives. We also continue to deliver very strong customer service performance.

We anticipate that the fourth quarter 2010 EPS will now be between 49 and 51 cents on a fully diluted basis, excluding restructuring charges. For the full year; we now anticipate organic revenue growth to be approximately 10 percent and diluted EPS to be $1.95 to $1.97, excluding restructuring charges.”

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.
