We calculate Adjusted EBITDA margin as Adjusted EBITDA divided by revenue.

Key Metrics and Non-GAAP Financial Measures

ironSource monitors the key business metrics set forth below to help evaluate the business and growth trends, establish budgets, measure the effectiveness of sales and marketing efforts, and assess operational efficiencies. The calculation of the key metrics discussed below may differ from other similarly titled metrics used by other companies, securities analysts or investors.

Customers Contributing More than $100,000 of Revenue

ironSource's larger customer relationships drive scale, improved unit economics and operating leverage in its business model, which improves ironSource's solutions and thereby increases the value proposition to all of ironSource's customers. To measure ironSource's ability to scale with its customers and attract large enterprises to its platform, ironSource counts the number of customers that contributed more than $100,000 in revenue in the trailing 12 months. ironSource's gross customer retention rate is calculated by comparing two twelve month periods to see how many customers in the previous period remain active customers in the current period. ironSource's customer count is subject to adjustments for acquisitions, consolidations, spin-offs and other market activity.

Dollar-Based Net Expansion Rate

ironSource believes the growth in the use of its platform by existing customers is an important measure of the health of its business and future growth prospects. ironSource monitors its performance in this area using an indicator management refers to as dollar-based net expansion rate. ironSource calculates dollar-based net expansion rate for a period by dividing current period revenue from a set of customers by prior period revenue of the same set of customers. Prior period revenue is the trailing 12-month revenue measured as of such prior period end. Current period revenue is the trailing 12-month revenue from the same customers as of the current period end. Management's calculation of dollar-based net expansion rate includes the effect of any customer renewals, expansion, contraction and churn, but excludes revenue from new customers.

Adjusted EBITDA and Adjusted EBITDA Margin

ironSource defines Adjusted EBITDA as income from continuing operations, net of income taxes, as adjusted for income taxes, financial expenses, net and depreciation and amortization, further adjusted for assets impairment, share-based compensation expense and fair value adjustment related to contingent consideration, acquisition-related costs and offering costs. ironSource defines Adjusted EBITDA Margin as Adjusted EBITDA calculated as a percentage of revenue. Adjusted EBITDA and Adjusted EBITDA Margin are included in this press release because they are key metrics used by management and our board of directors to assess our financial performance. Adjusted EBITDA and Adjusted EBITDA Margin are frequently used by analysts, investors and other interested parties to evaluate companies in our industry. ironSource management believes that Adjusted EBITDA and Adjusted EBITDA Margin are appropriate measures of operating performance because each eliminates the impact of expenses that do not relate directly to the performance of the underlying business.

Adjusted EBITDA and Adjusted EBITDA Margin are non-GAAP measures of our financial performance and should not be considered as alternatives to net loss as a measure of financial performance, as alternatives to cash flows from operations as a measure of liquidity, or as alternatives to any other performance measure derived in accordance with GAAP. Adjusted EBITDA and Adjusted EBITDA Margin should not be construed as inferences that our future results will be unaffected by unusual or other items. Additionally, Adjusted EBITDA and Adjusted EBITDA Margin are not intended to be measures of free cash flow for management's discretionary use, as they do not reflect our tax payments and certain other cash costs that may recur in the future, including, among other things, cash requirements for costs to replace assets being depreciated and amortized. Management compensates for these limitations by relying on our GAAP results in addition to using Adjusted EBITDA and Adjusted EBITDA Margin as supplemental measures. Our measures of Adjusted EBITDA and Adjusted EBITDA Margin are not necessarily comparable to similarly titled captions of other companies due to different methods of calculation. For more information on the non-GAAP financial measures, please see the reconciliation tables provided below. The accompanying tables have more details on the GAAP financial measures that are most directly comparable to non-GAAP financial measures and the related reconciliations between these financial measures. The Company has not reconciled its Adjusted EBITDA guidance to net income because net income is not accessible on a forward-looking basis. Certain items that impact Adjusted EBITDA are out of the Company's control and/or cannot be reasonably predicted. These items include, but are not limited to, share based compensation expenses. These items are uncertain, depend on various factors, and could have a material impact on GAAP reported results for the guidance period. Accordingly, a reconciliation to net income is not available without unreasonable effort. For more information regarding the non-GAAP financial measures discussed in this release, please see Annex A of this release for the reconciliations of GAAP financial measures to non-GAAP financial measures.
