Explanation of Non-GAAP Financial Measures

In addition to our results determined in accordance with generally accepted accounting principles in the United States (U.S. GAAP), we believe the following non-GAAP measures are useful in evaluating our operating performance. We use the following non-GAAP financial information to evaluate our ongoing operations and for internal planning and forecasting purposes. We believe that non-GAAP financial information, when taken collectively, may be helpful to investors because it provides consistency and comparability with past financial performance. However, non-GAAP financial information is presented for supplemental informational purposes only, has limitations as an analytical tool and should not be considered in isolation or as a substitute for financial information presented in accordance with U.S. GAAP. In particular, free cash flow is not a substitute for cash provided by (used in) operating activities. Additionally, the utility of free cash flow as a measure of our liquidity is further limited as it does not represent the total increase or decrease in our cash balance for a given period. In addition, other companies, including companies in our industry, may calculate similarly-titled non-GAAP measures differently or may use other measures to evaluate their performance, all of which could reduce the usefulness of our non-GAAP financial measures as tools for comparison. A reconciliation is provided above for each non-GAAP financial measure to the most directly comparable financial measure stated in accordance with U.S. GAAP. Investors are encouraged to review the related U.S. GAAP financial measures and the reconciliation of these non-GAAP financial measures to their most directly comparable U.S. GAAP financial measures, and not to rely on any single financial measure to evaluate our business.

Expenses Excluded from Non-GAAP Measures. We exclude stock-based compensation expense, which is a non-cash expense, from certain of our non-GAAP financial measures because we believe that excluding this item provides meaningful supplemental information regarding operational performance. We exclude employer payroll tax expenses related to stock-based compensation which is a cash expense, from certain of our non-GAAP financial measures because such expenses are dependent on the price of our common stock and other factors that are beyond our control and do not correlate to the operation of our business. We exclude amortization of acquired intangible assets, which is a non-cash expense, related to business combinations from certain of our non-GAAP financial measures because such expenses are related to business combinations and have no direct correlation to the operation of our business. We exclude acquisition-related and other expenses from certain of our non-GAAP financial measures because such expenses are related to business combinations and have no direct correlation to the operation of our business. Acquisition-related and other expenses can be cash or non-cash expenses and include third-party transaction costs and compensation expense for key acquired personnel. We exclude amortization of debt discount and issuance costs, which is a non-cash expense, from certain of our non-GAAP financial measures because such expenses have no direct correlation to the operation of our business.

Non-GAAP Gross Profit and Non-GAAP Gross Margin. We define non-GAAP gross profit and non-GAAP gross margin as U.S. GAAP gross profit and U.S. GAAP gross margin, respectively, excluding stock-based compensation and related employer payroll taxes and amortization of acquired intangible assets.

Non-GAAP Income (Loss) from Operations and Non-GAAP Operating Margin. We define non-GAAP income (loss) from operations and non-GAAP operating margin as U.S. GAAP loss from operations and U.S. GAAP operating margin, respectively, excluding stock-based compensation and related employer payroll taxes, amortization of acquired intangible assets, and acquisition-related and other expenses.

Non-GAAP Net Income (Loss) and Non-GAAP Net Income (Loss) per Share, Diluted. We define non-GAAP net income (loss) as GAAP net income (loss) adjusted for stock-based compensation and related employer payroll taxes, amortization of acquired intangible assets, acquisition-related and other expenses, loss on extinguishment of debt, and a non-GAAP provision for (benefit from) income taxes. Generally, the difference between our GAAP and non-GAAP income tax expense (benefit) is primarily due to adjustments in stock-based compensation and related employer payroll taxes, amortization of acquired intangibles associated with business combinations, acquisition-related and other expenses, and amortization of debt discount and issuance costs. We define non-GAAP net loss per share, diluted, as non-GAAP net loss divided by the weighted-average common shares outstanding. Calculation of non-GAAP net loss per share, diluted excludes all potentially dilutive securities as their effect is antidilutive. We define non-GAAP net income per share, diluted, as non-GAAP net income divided by the weighted-average common shares outstanding, adjusted for dilutive potential shares that were assumed outstanding during period. Currently, potential dilutive effect mainly consists of employee equity incentive plans and convertible senior notes. We believe that excluding these items from non-GAAP net income (loss) per share, diluted, provides management and investors with greater visibility into the underlying performance of our core business operating results.

Free Cash Flow and Free Cash Flow Margin. Free cash flow is a non-GAAP financial measure that we calculate as net cash provided by (used in) operating activities less cash used for purchases of property and equipment and capitalized internal-use software. Free cash flow margin is calculated as free cash flow divided by revenue. We believe that free cash flow and free cash flow margin are useful indicators of liquidity that provide information to management and investors about the amount of cash generated from our operations that, after the investments in property and equipment and capitalized internal-use software, can be used for strategic initiatives, including investing in our business, and strengthening our financial position. We believe that historical and future trends in free cash flow and free cash flow margin, even if negative, provide useful information about the amount of cash generated (or consumed) by our operating activities that is available (or not available) to be used for strategic initiatives. For example, if free cash flow is negative, we may need to access cash reserves or other sources of capital to invest in strategic initiatives. One limitation of free cash flow and free cash flow margin is that they do not reflect our future contractual commitments. Additionally, free cash flow does not represent the total increase or decrease in our cash balance for a given period.
