Fourth Quarter 2016 Business and Product Release Highlights:

• Debuted a proprietary global media plan functionality to support larger, more complex social campaigns with multiple objectives.
• Launched support for the Store Visits objective, giving marketers a better view of the impact of Facebook advertising on offline store traffic.
• Developed Search Intent Harvesting tools that allow marketers to leverage search signals in social campaigns to maximize performance of cross channel initiatives.
• Invited select customers to participate in the Platform Beta program, which delivers improved scale, faster data loading and application speed, combined with significant usability improvements.
• Continued to update optimization tools, further enhancing Marin Software’s ability to deliver performance for marketers. Improvements include: faster bid calculations, easier bidding setup with advanced clustering technology, device-specific goals, forecasting, and budget allocation tools.

Financial Outlook:

Non-GAAP loss from operations and non-GAAP net loss per share excludes the effects of stock-based compensation, amortization of internally developed software, amortization of intangible assets, noncash expenses related to warrants, non-recurring costs associated with acquisitions and restructurings, and capitalization of internally developed software.

Additionally, the Company does not reconcile its forward-looking non-GAAP financial measures, non-GAAP loss from operations and non-GAAP net loss per share, due to variability between revenues and non-cash items such as stock-based compensation. The GAAP measures, loss from operations and net loss per share, include stock-based compensation expense, which is affected by hiring and retention needs, as well as the future price of Marin Software’s stock. As a result, reconciliation of the forward-looking non-GAAP financial measures to the corresponding GAAP measures cannot be made without unreasonable effort.

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 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 income (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 and for bonus compensation purposes, 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.
