John Stroup, President and CEO of Belden Inc., said, “We’re pleased with our strong start to the year.

Year-over-year operating income margin expansion is a clear highlight and a direct result of our business transformation and commitment to continuous improvement.”

Outlook

“Although the global macroeconomic environment has proven challenging and difficult to predict, we feel confident that our portfolio, business system, and focus on execution provide a level of stability and predictability. Therefore, we are increasing our earnings outlook for the full year,” said Mr. Stroup.

RECONCILIATION OF NON-GAAP MEASURES

(Unaudited)

We define free cash flow, which is a non-GAAP financial measure, as net cash provided by operating activities adjusted for acquisition and divestiture transaction costs, capital expenditures net of the proceeds from the disposal of tangible assets, and non-recurring tax payments related to divestitures and settlement of a tax sharing agreement. We believe free cash flow provides useful information to investors regarding our ability to generate cash from business operations that is available for acquisitions and other investments, service of debt principal, dividends and share repurchases. We use free cash flow, as defined, as one financial measure to monitor and evaluate performance and liquidity. Non-GAAP financial measures should be considered only in conjunction with financial measures reported according to accounting principles generally accepted in the United States. Our definition of free cash flow may differ from definitions used by other companies.

RECONCILIATION OF NON-GAAP MEASURES

(Unaudited)

In addition to reporting financial results in accordance with accounting principles generally accepted in the United States, we provide non-GAAP operating results adjusted for certain items including asset impairments, purchase accounting effects related to acquisitions, acquisition and divestiture transaction costs, revenue and cost of sales deferrals, severance and other restructuring costs, gains (losses) recognized on the disposal of businesses and tangible assets, amortization of intangible assets, gains (losses) on debt extinguishment, and other costs. We utilize the adjusted results to review our ongoing operations without the effect of these adjustments and for comparison to budgeted operating results. We believe the adjusted results are useful to investors because they help them compare our results to previous periods and provide important insights into underlying trends in the business and how management oversees our business operations on a day-to-day basis. Adjusted results should be considered only in conjunction with results reported according to accounting principles generally accepted in the United States.
