The Company’s third quarter and 2022 financial outlook is based on a number of assumptions that are subject to change and many of which are outside the Company’s control. If actual results vary from these assumptions, the Company’s expectations may change. There can be no assurance that the Company will achieve these results.

The Company does not provide guidance for operating loss, the most directly comparable GAAP measure to Non-GAAP operating loss, and similarly cannot provide a reconciliation between its forecasted Non-GAAP operating loss and Non-GAAP net loss per share and these comparable GAAP measures without unreasonable effort due to the unavailability of reliable estimates for certain items. These items are not within the Company’s control and may vary greatly between periods and could significantly impact future financial results.

Use of Non-GAAP Financial Measures

We have provided in this press release certain financial information that has not been prepared in accordance with generally accepted accounting principles in the United States (“GAAP”). Our management uses these Non-GAAP financial measures internally in analyzing our financial results and believes that use of these Non-GAAP financial measures is useful to investors as an additional tool to evaluate ongoing operating results and trends and in comparing our financial results with other companies in our industry, many of which present similar Non-GAAP financial measures. Non-GAAP financial measures are not meant to be considered in isolation or as a substitute for comparable financial measures prepared in accordance with GAAP and should be read only in conjunction with our consolidated financial statements prepared in accordance with GAAP. A reconciliation of our historical Non-GAAP financial measures to the most directly comparable GAAP measures has been provided in the financial statement tables included in this press release, and investors are encouraged to review these reconciliations.

Annual Revenue Run-Rate (ARR)

We calculate annual revenue run-rate (“ARR”) at the end of each month as the sum of: (1) contractual monthly recurring revenue at the end of the period, which includes platform subscription fees, invoiced growth adjustments, feed management subscription fees, recurring professional services revenue, and other recurring revenue, multiplied by twelve to prospectively annualize recurring revenue, and (2) the sum of the trailing twelve-month non-recurring and variable revenue, which includes one-time partner integrations, one-time fees, payments revenue share, and any other revenue that is non-recurring and variable.

Subscription ARR

We calculate subscription annual revenue run-rate (“ARR”) at the end of each month as contractual monthly recurring revenue at the end of the period, which includes platform subscription fees, invoiced growth adjustments, feed management subscription fees, recurring professional services revenue, and other recurring revenue, multiplied by twelve to prospectively annualize recurring revenue.

Enterprise Account Metrics

To measure the effectiveness of our ability to execute against our growth strategy, particularly within the mid-market and enterprise business segments, we calculate ARR attributable to Enterprise Accounts. We define Enterprise Accounts as accounts with at least one unique Enterprise plan subscription or an enterprise level feed management subscription (collectively “Enterprise Accounts”). These accounts may have more than one Enterprise plan or a combination of Enterprise plans and Essentials plans.

Average Revenue Per Account

We calculate average revenue per account (ARPA) for accounts above the ACV threshold at the end of a period by including customer-billed revenue and an allocation of partner and services revenue, where applicable. We allocate partner revenue, where applicable, primarily based on each customer’s share of GMV processed through that partner’s solution. For partner revenue that is not directly linked to customer usage of a partner’s solution, we allocate such revenue based on each customer’s share of total platform GMV. Each account’s partner revenue allocation is calculated by taking the account’s trailing twelve-month partner revenue, then dividing by twelve to create a monthly average to apply to the applicable period in order to normalize ARPA for seasonality.

Adjusted EBITDA

We define Adjusted EBITDA as our net loss, excluding the impact of stock-based compensation expense and related payroll tax expense, third party acquisition-related costs, and other acquisition related expenses, including contingent compensation arrangements entered into in connection with acquisitions, depreciation and amortization expense, interest income, interest expense, changes in fair value of financial instruments, and our provision for income taxes. The most directly comparable GAAP measure is net loss.

Non-GAAP Operating Loss

We define Non-GAAP Operating Loss as our GAAP Loss from operations, excluding the impact of stock-based compensation expense and related payroll tax expense, third party acquisition-related costs, and other acquisition related expenses, including contingent compensation arrangements entered into in connection with acquisitions and amortization of acquisition-related intangible assets. The most directly comparable GAAP measure is our loss from operations.

Non-GAAP Net Loss

We define Non-GAAP Net Loss as our GAAP net loss, excluding the impact of stock-based compensation expense and related payroll tax expense, third party acquisition-related costs, and other acquisition related expenses, including contingent compensation arrangements entered into in connection with acquisitions, amortization of acquisition-related intangible assets and changes in fair value of financial instruments. The most directly comparable GAAP measure is our net loss.

Non-GAAP Net Loss per Share

We define Non-GAAP Net Loss per Share as our Non-GAAP Net Loss, defined above, divided by our basic and diluted GAAP weighted average shares outstanding. The most directly comparable GAAP measure is our net loss per share.

Free Cash Flow

We define Free Cash flow as our GAAP cash flow from operating activities plus our GAAP purchases of property and equipment (Capital Expenditures). The most directly comparable GAAP measure is our cash flow from operating activities.
