Non-GAAP Measures of Financial Performance

To supplement our financial statements, which are presented on the basis of U.S. generally accepted accounting principles (GAAP), the followingnon-GAAP measures of financial performance are included in this release: revenue growth rate at constant currency, adjusted gross profit and adjusted gross margin, adjusted income from operations and adjusted operating margin, earnings before interest, taxes, depreciation and amortization (EBITDA), adjusted EBITDA, adjusted net income, adjusted net income per share, adjusted earnings per diluted share (EPS), adjusted cost of sales, adjusted research & development expense, adjusted selling, general and administrative expense and income tax expense. The Company provides organic revenue growth rates in constant currency to exclude the impact of both foreign currency translation, and the impact of acquisition revenue for current year periods that have no prior year comparable, in order to facilitate a comparison of its current revenue performance to its past revenue performance. The Company provides revenue growth rates in constant currency in order to facilitate a comparison of its current revenue performance to its past revenue performance. To calculate revenue growth rates in constant currency, the Company converts actual net sales from local currency to U.S. dollars using constant foreign currency exchange rates in the current and prior period.

The Company’snon-GAAP financial results and/ornon-GAAP guidance exclude the impact of: acquisition and integration costs related to the Company’s acquisitions of TangenX Technology Corporation, Spectrum Lifesciences, LLC (formerly known as Spectrum, Inc.), and C Technologies Inc.; inventorystep-up charges; intangible amortization costs;non-cash interest expense; the impact on tax of intangible amortization and acquisition costs; and, in the case of EBITDA, cash interest expense related to the Company’s convertible debt. These costs are excluded because management believes that such expenses do not have a direct correlation to future business operations, nor do the resulting charges recorded accurately reflect the performance of our ongoing operations for the period in which such charges are recorded.

A reconciliation of GAAP to adjustednon-GAAP financial measures is included as an attachment to this press release. When analyzing the Company’s operating performance and guidance investors should not considernon-GAAP measures as substitutable for the comparable financial measures prepared in accordance with GAAP.
