Non-GAAP Financial Measures

To complement our condensed consolidated statements of operations, we use non-GAAP financial measures of adjusted selling and marketing (“S&M”) expenses, adjusted research and development (“R&D”) expenses, adjusted general and administrative (“G&A”) expenses, and adjusted EBITDA. Management believes that these non-GAAP financial measures complement our GAAP amounts and such measures are useful to securities analysts and investors to evaluate our ongoing results of operations when considered alongside our GAAP measures. The presentation of these non-GAAP measures is not meant to be considered in isolation or as an alternative to net loss as an indicator of our performance.

The following table provides a reconciliation from GAAP S&M expenses to non-GAAP adjusted S&M expenses (amounts in thousands):

The following table provides a reconciliation from GAAP R&D expenses to non-GAAP adjusted R&D expenses (amounts in thousands):

The following table provides a reconciliation from GAAP G&A expenses to non-GAAP adjusted G&A expenses (amounts in thousands):

The following table provides a reconciliation from net loss to non-GAAP adjusted EBITDA, with net loss being the most directly comparable GAAP measure (amounts in thousands):

We present adjusted EBITDA, which is net loss excluding adjustments that are outlined in the quantitative reconciliation provided above, as a supplemental measure of our performance and because we believe this measure is frequently used by securities analysts, investors, and other interested parties in the evaluation of companies in our industry. The adjusted EBITDA measure excludes the financial impact of items management does not consider in assessing our ongoing operating performance, and thereby facilitates review of our operating performance on a period-to-period basis.

In evaluating adjusted EBITDA, one should be aware that in the future we may incur expenses similar to the adjustments noted above. Our presentation of adjusted EBITDA should not be construed as an inference that our future results will be unaffected by these types of adjustments. Adjusted EBITDA is not a measurement of our financial performance under GAAP and should not be considered as an alternative to net loss, operating loss, or any other performance measures derived in accordance with GAAP or as an alternative to cash flow from operating activities as a measure of our liquidity.

Our adjusted EBITDA measure has limitations as an analytical tool, and should not be considered in isolation or as a substitute for analysis of our results as reported under GAAP. Some of these limitations are:

• it does not reflect our cash expenditures, future requirements for capital expenditures, or contractual commitments;
• it does not reflect changes in, or cash requirements for, our working capital needs;
• it does not reflect stock-based compensation, which is an ongoing expense;
• although depreciation and amortization are non-cash charges, the assets being depreciated and amortized will often have to be replaced in the future, and our adjusted EBITDA measure does not reflect any cash requirements for such replacements;
• it is not adjusted for all non-cash income or expense items that are reflected in our condensed consolidated statements of cash flows;
• it does not reflect the impact of earnings or charges resulting from matters we consider not to be indicative of our ongoing operations;
• it does not reflect limitations on or costs related to transferring earnings from our subsidiaries to us; and
• other companies in our industry may calculate this measure differently than we do, limiting its usefulness as a comparative measure.

Because of these limitations, adjusted EBITDA should not be considered as a measure of discretionary cash available to us to invest in the growth of our business or as a measure of cash that will be available to use to meet our obligations. You should compensate for these limitations by relying primarily on our GAAP results and using adjusted EBITDA only supplementally.
