Discussion of Non-GAAP Financial Measures

We use certain non-GAAP financial measures, including those concerning our financial outlook, to supplement the performance measures in our consolidated financial statements, which are presented in accordance with GAAP. A reconciliation of these non-GAAP measures to the closest GAAP measure can be found later in this release. The timing and impact of any adjustments to arrive at the corresponding GAAP financial measures concerning our financial outlook are inherently dependent on future events that are typically uncertain or that may be outside of our control. These non-GAAP financial measures include non-GAAP gross profit, non-GAAP gross margin, non-GAAP operating expenses, non-GAAP operating income, non-GAAP operating margin, non-GAAP tax rate, non-GAAP net income, non-GAAP pro forma diluted earnings per share, and non-GAAP pro forma weighted-average share count.

We use these non-GAAP financial measures for financial and operational decision-making and as a means to assist us in evaluating period-to-period comparisons. By excluding certain items that may not be indicative of our recurring core operating results, we believe that, non-GAAP gross profit, non-GAAP gross margin, non-GAAP operating expenses, non-GAAP operating income, non-GAAP operating margin, non-GAAP tax rate, non-GAAP net income, non-GAAP pro forma diluted earnings per share, and non-GAAP pro forma weighted-average share count provide meaningful supplemental information regarding our performance. Accordingly, we believe these non-GAAP financial measures are useful to investors and others because they allow for additional information with respect to financial measures used by management in its financial and operational decision-making and they may be used by our institutional investors and the analyst community to help them analyze the health of our business. However, there

are a number of limitations related to the use of non-GAAP financial measures, and these non-GAAP measures should be considered in addition to, not as a substitute for or in isolation from, our financial results prepared in accordance with GAAP. Other companies, including companies in our industry, may calculate these non-GAAP financial measures differently or not at all, which reduces their usefulness as comparative measures.

We adjust the following items from one or more of our non-GAAP financial measures:

Stock-based compensation expense

We exclude non-cash stock-based compensation expense from certain of our non-GAAP financial measures because we believe that excluding this item provides meaningful supplemental information regarding operational performance. In particular, companies calculate non-cash stock-based compensation expense using a variety of valuation methodologies and subjective assumptions. Moreover, stock-based compensation expense is a non-cash charge that can vary significantly from period to period for reasons that are unrelated to our core operating performance, and therefore excluding this item provides investors and other users of our financial information with information that allows meaningful comparisons of our business performance across periods.

Acquisition-related costs

We exclude acquisition-related costs incurred in connection with our acquisitions, which we generally would have not otherwise incurred in the periods presented as part of our continuing operations. Acquisition-related costs include certain incremental expenses incurred to effect a business combination such as third-party costs: advisory, legal, accounting, valuation, and other professional fees. We believe that providing the non-GAAP measures excluding these costs assists our investors because such costs are not reflective of our ongoing operating results.

Employer payroll taxes related to stock-based compensation resulting from our IPO

We exclude employer payroll taxes related to the time-based vesting and net settlement of restricted stock units in connection with our initial public offering (the “IPO”), because this does not correlate to the operation of our business. We believe that excluding this item provides meaningful supplemental information regarding operational performance given the amount of employer payroll tax-related items on employee stock transactions was immaterial prior to our IPO.

Income tax effect

This represents the impact of the non-GAAP adjustments on an after-tax basis and one-off discrete tax adjustments that are unrelated to our core operating performance in connection with the presentation of non-GAAP net income and non-GAAP net income per diluted share. This approach is designed to enhance investors’ ability to understand the impact of our non-GAAP tax expense on our current operations, provide improved modeling accuracy, and substantially reduce fluctuations caused by GAAP to non-GAAP adjustments.

Non-GAAP pro forma weighted-average shares to compute non-GAAP pro forma net income per share

We present non-GAAP pro forma weighted-average shares, assuming our redeemable convertible preferred stock is converted from the beginning of each respective periods presented, to provide meaningful supplemental information regarding EPS trend on a consistent basis. All of our outstanding redeemable preferred stock converted into the equivalent number of shares of common stock in connection with our IPO.

Moreover, we operate in a very competitive and rapidly changing environment, and new risks may emerge from time to time. It is not possible for our management to predict all risks, nor can we assess the impact of all factors on our business or the extent to which any factor(s) may cause actual results or outcomes to differ materially from those contained in any forward-looking statements we may make.
