We use these non-GAAP financial measures to evaluate our operating performance and trends and make planning decisions. We believe that these non-GAAP financial measures help identify underlying trends in our business that could otherwise be masked by the effect of the expenses and other items that we exclude in these non-GAAP financial measures. Accordingly, we believe that these non-GAAP financial measures provide useful information to investors and others in understanding and evaluating our operating results, enhancing the overall understanding of our past performance and future prospects, and allowing for greater transparency with respect to a key financial metric used by our management in its financial and operational decision-making. Non-GAAP financial measures should not be considered in isolation of, or as an alternative to, measures prepared in accordance with U.S. GAAP. We define adjusted EBITDA as net income (loss) adjusted to exclude the impact of depreciation, stock-based compensation expense, interest income, interest expense, other income (expense), income taxes and other items that we do not consider representative of our underlying operating performance. We define adjusted EBITDA margin as adjusted EBITDA divided by revenue. We calculate gross margin excluding the impact of tariff duties and refunds as gross profit dollars removing the impact of tariffs imposed on goods imported to the U.S. from China and any tariffs refunds subject to a tariff refund claim approved by U.S. Customs and Border Protection divided by revenue. We define free cash flow as net cash from operations less purchases of property and equipment. We calculate adjusted EBITDA excluding the impact of tariffs as net income (loss) excluding the impact of tariffs imposed on goods manufactured in China and any tariffs refunds subject to a tariff refund claim approved by U.S. Customs and Border Protection and adjusted to exclude the impact of depreciation, stock-based compensation expense, interest income, interest expense, other income (expense), income taxes and other items that we do not consider representative of our underlying operating performance. We do not provide a reconciliation of forward-looking non-GAAP financial measures to their comparable GAAP financial measures because we cannot do so without unreasonable effort due to unavailability of information needed to calculate reconciling items and due to the variability, complexity and limited visibility of the adjusting items that would be excluded from the non-GAAP financial measures in future periods. When planning, forecasting and analyzing future periods, we do so primarily on a non-GAAP basis without preparing a GAAP analysis as that would require estimates for certain items such as stock-based compensation, which is inherently difficult to predict with reasonable accuracy. Stock-based compensation expense is difficult to estimate because it depends on our future hiring and retention needs, as well as the future fair market value of our common stock, all of which are difficult to predict and subject to constant change. In addition, for purposes of setting annual guidance, it would be difficult to quantify stock-based compensation expense for the year with reasonable accuracy in the current quarter. As a result, we do not believe that a GAAP reconciliation would provide meaningful supplemental information about our outlook.#19Reconciliation of Net Income (Loss) to Adjusted EBITDA Net income (loss) Add (deduct): Depreciation and amortization Stock-based compensation expense Interest income Interest expense Other income, net Provision for (benefit from) income taxes Restructuring and related expenses Legal and transaction related costs (2) Adjusted EBITDA Revenue Adjusted EBITDA margin (1) Note: $ in thousands, unaudited.
