Annual Recurring Revenue ("ARR"): ARR is calculated as the sum of the annualized value of our subscription contracts as of the measurement date, including existing customers with expired contracts that we expect to be renewed. Our ARR amounts exclude professional services, overages from subscription customers and Legacy revenue.

**Non-GAAP Financial Measures**

In addition to our results determined in accordance with generally accepted accounting principles in the United States, or "GAAP", we consider our non-GAAP operating income (loss), non-GAAP net income (loss), Adjusted EBITDA, and free cash flow in evaluating our operating performance. We define non-GAAP operating income (loss) as net income (loss) excluding, interest expense, other (income) expense, net, provision for income taxes, stock-based compensation, amortization of acquired intangible assets, shareholder activism related costs, restructuring costs, impairment charges for underutilized real estate, litigation related expenses from a shareholder class action suit, and certain other costs. We define non-GAAP net income (loss) as net income (loss) excluding stock-based compensation, amortization of acquired intangible assets, shareholder activism related costs, restructuring costs, impairment charges for underutilized real estate, litigation-related expenses from a shareholder class action suit, and certain other costs. We define Adjusted EBITDA as net income (loss) excluding interest expense, other (income) expense, net, provision for income taxes, depreciation and amortization, amortization of acquired intangible assets, amortization of cloud implementation costs, stock-based compensation, restructuring costs, impairment charges for underutilized real estate, litigation related expenses from a shareholder class action suit, and shareholder activism related costs. We define free cash flow as net cash provided by (used in) operating activities, less purchases of property and equipment.

We use non-GAAP operating income (loss), non-GAAP net income (loss), and Adjusted EBITDA to evaluate our ongoing operations and for internal planning and forecasting purposes, and we use free cash flow to measure and evaluate cash generated through normal business operations. We believe non-GAAP operating income (loss), non-GAAP net income (loss), and Adjusted EBITDA may be helpful to investors because they provide consistency and comparability with past financial performance. We believe free cash flow may be helpful to investors because it reflects that some purchases of property and equipment are necessary to support ongoing operations, while providing a measure of cash available to acquire customers, expand within existing customers and otherwise pursue our business strategies.

However, these non-GAAP financial measures are each presented for supplemental informational purposes only, have limitations as analytical tools and should not be considered in isolation or as a

------

substitute for financial information presented in accordance with GAAP. Non-GAAP financial measures have no standardized meanings prescribed by GAAP and are not prepared under a comprehensive set of accounting rules or principles. In addition, other companies, including companies in our industry, may calculate similarly titled non-GAAP financial measures differently or may use other measures to evaluate their performance, all of which could reduce the usefulness of our non-GAAP financial measure as a tool for comparison.

We do not provide a quantitative reconciliation of the forward-looking non-GAAP financial measures included in this press release to the most directly comparable GAAP measures due to the high variability and difficulty to predict certain items excluded from these non-GAAP financial measures; in particular, the effects of stock-based compensation expense, and restructuring and transaction expenses. We expect the variability of these excluded items may have a significant, and potentially unpredictable impact on our future GAAP financial results.

Reconciliations of these non-GAAP financial measures to their most directly comparable GAAP financial measure are included in the tables at the end of this press release.

Such statements are based on our current beliefs, expectations, and assumptions about future events or conditions, which are subject to inherent risks and uncertainties, including our ability to attract new customers and expand sales to existing customers; declines in our growth rate; fluctuation in our performance; our history of net losses; competition; technological development in our markets; decline in demand for our solutions; our ability to expand our sales and marketing capabilities and otherwise achieve our growth; the impact of the resumption of in-person marketing activities on our customer growth rate; disruptions or other issues with our technology or third-party services; compliance with data privacy, import and export controls, customs, sanctions and other laws and regulations; intellectual property matters; and matters relating to our common stock, along with the other risks and uncertainties discussed in the filings we make from time to time with the Securities and Exchange Commission.
