19 Appendix

20 This presentation contains certain financial measures not presented in accordance with U.S. generally accepted accounting principles ("GAAP"), including adjusted gross margin, adjusted gross margin %, adjusted income from operations, adjusted EBITDA, adjusted EBITDA margin % (collectively, the "non-GAAP financial measures"). These non-GAAP financial measures are not calculated in accordance with GAAP and should not be considered in isolation from, or as a substitute for, the most directly comparable GAAP measures, and may not be comparable to similarly titled measures used by other companies. Management uses these non-GAAP financial measures, together with the comparable GAAP measures, to evaluate the Company's operating performance and underlying business trends across periods on a consistent basis, and to assist in operational and financial decision-making, including with respect to internal budgeting and resource allocation. Reconciliations of each non-GAAP financial measure to its most directly comparable GAAP measure are set forth in the tables accompanying this presentation. Non-GAAP Financial Measures Footnotes
