Non-GAAP Financial Measures

Marin uses certain non-GAAP financial measures in this release. Marin uses these non-GAAP financial measures internally in analyzing its financial results and believes they are useful to investors, as a supplement to GAAP measures, in evaluating its ongoing operational performance. Marin believes that the use of these non-GAAP financial measures provides an additional tool for investors to use in evaluating 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 to investors. Non-GAAP financial measures that Marin uses may differ from measures that other companies may use.

Non-GAAP financial measures should not be considered in isolation from, or as a substitute for, financial information prepared in accordance with GAAP. A reconciliation of the non-GAAP financial measures to their most directly comparable GAAP measures has been provided in the financial statement tables included below in this press release. Investors are encouraged to review the reconciliation of these non-GAAP financial measures to their most directly comparable GAAP financial measures.

Non-GAAP expenses, measures and net loss per share. Marin defines non-GAAP sales and marketing, non-GAAP research and development, non-GAAP general and administrative, non-GAAP gross profit, non-GAAP operating loss and non-GAAP net loss as the respective GAAP balances, adjusted for stock-based compensation expense, the amortization of intangible assets, the capitalization of internally developed software, noncash expenses related to the issuance of warrants, the amortization of internally developed software, the benefit from income taxes related to acquisition and the non-recurring costs associated with acquisitions and restructurings. Non-GAAP net loss per share is calculated as non-GAAP net loss divided by the weighted average shares outstanding that are adjusted to assume the conversion of outstanding preferred shares to common shares as of the beginning of the period.

Adjusted EBITDA. Marin defines Adjusted EBITDA as net loss, adjusted for stock-based compensation expense, depreciation, the amortization of internally developed software, the amortization of intangible assets, the capitalization of internally developed software, interest expense, net, the benefit from or provision for income taxes, other income or expenses, net and the non-recurring costs associated with acquisitions and restructurings. These amounts are often excluded by other companies to help investors understand the operational performance of their business. The Company uses Adjusted EBITDA as a measurement of its operating performance because it assists in comparing the operating performance on a consistent basis by removing the impact of certain non-cash and non-operating items. Adjusted EBITDA reflects an additional way of viewing aspects of the operations that Marin believes, when viewed with the GAAP results and the accompanying reconciliations to corresponding GAAP financial measures, provide a more complete understanding of factors and trends affecting its business.

Non-GAAP constant currency revenues and growth. Marin defines non-GAAP constant currency revenues as total revenues excluding the impact of foreign exchange rate movements, and uses it to determine the constant currency revenue growth on a year-over-year basis. Non-GAAP constant currency revenues are calculated by translating current quarter or year-to-date revenues using the average prior period exchange rates. Constant currency revenue growth (expressed as a percentage) is calculated by determining the increase in current quarter and year-to-date revenues over prior period revenues, where current quarter international revenues are translated using prior period exchange rates. The Company considers non-GAAP constant currency revenues and growth as useful metrics as they facilitate management's internal comparison to historical performance, because they exclude the effects of foreign currency volatility that are not indicative of the Company’s operating results. Marin believes they provide useful supplemental information to investors about the financial performance of the business, enable a comparison of financial results between periods where certain items may vary independent of business performance and allow for greater transparency with respect to key metrics used by management in operating the business.
