Forward-Looking Statements

This press release includes forward-looking statements within the meaning of the "safe harbor" provisions of the Private Securities Litigation Reform Act of 1995. All statements contained in this press release other than statements of historical fact, including statements regarding our future results of operations and financial position, business strategy and plans and objectives for future operations, are forward-looking statements and represent our views as of the date of this press release. The words “anticipate,” "believe,” “continue,” “estimate,” “expect,” “intend,” “may,” “will” and similar expressions are intended to identify forward-looking statements. We have based these forward-looking statements on our current expectations and projections about future events and financial trends that we believe may affect our financial condition, results of operations, business strategy, short-term and long-term business operations and objectives and financial needs. These forward-looking statements are subject to a number of assumptions and risks and uncertainties, many of which involve factors or circumstances that are beyond our control that could affect our financial results. These risks and uncertainties are detailed in the sections titled "Risk Factors" and "Management's Discussion and Analysis of Financial Condition and Results of Operations" in our Annual Report on Form 10-K for the year ended December 31, 2022, our Quarterly Report on Form 10-Q for the quarter ended September 30, 2023 and other filings that we make from time to time with the SEC, which are available on the SEC's website at sec.gov. Moreover, we operate in a very competitive and rapidly changing environment. New risks 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, or combination of factors, may cause actual results to differ materially from those contained in any forward-looking statements we may make. In light of these risks, uncertainties and assumptions, the future events and trends discussed in this press release may not occur and actual results could differ materially and adversely from those anticipated or implied in any forward-looking statements. Except as required by law, we are under no obligation to update these forward-looking statements subsequent to the date of this press release, or to update the reasons if actual results differ materially from those anticipated in the forward-looking statements.

Non-GAAP Financial Measures

To supplement our consolidated financial statements, which are prepared and presented in accordance with GAAP, we use certain non-GAAP financial measures, as described below, to understand and evaluate our core operating performance. These non-GAAP financial measures, which may be different than similarly titled measures used by other companies, are presented to enhance the overall understanding of our financial performance and should not be considered a substitute for, or superior to, the financial information prepared and presented in accordance with GAAP.

We believe that these non-GAAP financial measures provide useful information about our financial performance, enhance the overall understanding of our past performance and future prospects and allow for greater transparency with respect to important metrics used by management for financial and operational decision-making. We include these non-GAAP financial measures to present our financial performance using a management view and because we believe that these measures provide an additional comparison of our core financial performance over multiple periods with other companies in our industry.

Reconciliations of non-GAAP financial measures to the most directly comparable GAAP financial measures are included in the financial tables accompanying this press release.

Calculated Current Billings: We define calculated current billings, a non-GAAP financial measure, as total revenue recognized in a period plus the change in current deferred revenue in the corresponding period. We believe that calculated current billings is a key metric to measure our periodic performance. Given that most of our customers pay in advance (including multi-year contracts), but we generally recognize the related revenue ratably over time, we use calculated current billings to measure and monitor our ability to provide our business with the working capital generated by upfront payments from our customers. We believe that calculated current billings, which excludes deferred revenue for periods beyond twelve months in a customer’s contractual term, more closely correlates with annual contract value and that the variability in total billings, depending on the timing of large multi-year contracts and the preference for annual billing versus multi-year upfront billing, may distort growth in one period over another.

Free Cash Flow and Unlevered Free Cash Flow: We define free cash flow, a non-GAAP financial measure, as net cash provided by operating activities less purchases of property and equipment and capitalized software development costs. We believe free cash flow is an important liquidity measure of the cash that is available (if any), after purchases of property and equipment and capitalized software development costs, for investment in our business and to make acquisitions. We believe that free cash flow is useful as a liquidity measure because it measures our ability to generate or use cash. We define unlevered free cash flow as free cash flow plus cash paid for interest and other financing costs. We believe unlevered free cash flow is useful as a liquidity measure as it measures the cash that is available to invest in our business and meet our current debt obligations and future financing needs. However, given our debt obligations, non-cancelable commitments and other contractual obligations, unlevered free cash flow does not represent residual cash flow available for discretionary expenses.

Non-GAAP Income from Operations and Non-GAAP Operating Margin: We define these non-GAAP financial measures as their respective GAAP measures, excluding the effect of stock-based compensation, acquisition-related expenses, restructuring expenses, costs related to the intra-entity asset transfers resulting from the internal restructuring of legal entities, and amortization of acquired intangible assets. Acquisition-related expenses include transaction and integration expenses, as well as costs related to the intercompany transfer of acquired intellectual property. Restructuring expenses include non-ordinary course severance, employee related benefits, and other charges. We believe that the exclusion of these expenses provides for a useful comparison of our operating results to prior periods and to our peer companies, which commonly exclude restructuring expenses.

Non-GAAP Net Income and Non-GAAP Earnings Per Share: We define non-GAAP net income as GAAP net loss, excluding the effect of stock-based compensation, acquisition-related expenses, restructuring expenses and amortization of acquired intangible assets, including the applicable tax impacts. In addition, we exclude the tax impact and related costs of intra-entity asset transfers resulting from the internal restructuring of legal entities as well as deferred income tax benefits recognized in connection with acquisitions. We use non-GAAP net income to calculate non-GAAP earnings per share.

Non-GAAP Gross Profit and Non-GAAP Gross Margin: We define non-GAAP gross profit as GAAP gross profit, excluding the effect of stock-based compensation and amortization of acquired intangible assets. Non-GAAP gross margin is defined as non-GAAP gross profit as a percentage of revenue.

Non-GAAP Sales and Marketing Expense, Non-GAAP Research and Development Expense and Non-GAAP General and Administrative Expense: We define these non-GAAP measures as their respective GAAP measures, excluding stock-based compensation, acquisition-related expenses and costs related to intra-entity asset transfers resulting from the internal restructuring of legal entities.
