Marin Software Announces Second Quarter Financial Results

San Francisco, CA (August 7, 2020) – Marin Software Incorporated (NASDAQ: MRIN), a leading provider of digital marketing software for performance-driven advertisers and agencies, today announced financial results for the second quarter ended June 30, 2020.

“In the second quarter, Marin continued to help advertisers drive performance during the COVID-19 pandemic, adjusting their online marketing investments to reflect changing market dynamics and customer behavior. Via MarinOne, our next generation, cross-channel platform, Marin clients were able to leverage all client views and dashboards to easily spot and react to changes across all lines of business. Marin also expanded our performance reporting for devices to provide advertisers with fine-grained analytics and control of their online advertising investments across smartphones, tablets, and PCs, especially as customer behavior adjusts with the new patterns of work from home and remote learning,” said Chief Executive Officer Chris Lien.

Second Quarter 2020 Business and Product Release Highlights:

Second Quarter 2020 Financial Updates:

Reconciliations of GAAP to non-GAAP financial measures have been provided in the financial statement tables included in this press release. An explanation of these measures is also included below, under the heading “Non-GAAP Financial Measures.”

In July 2020, after the second quarter ended June 30, 2020, the Company commenced the implementation of a restructuring and reduction in force plan to reduce the Company’s operating costs and address the impact of the COVID-19 pandemic, which is expected to result in the reduction of the Company’s global workforce by approximately 60 employees, approximately half of which are located outside of the United States. The Company estimates that the restructuring plan and other planned cost savings that the Company plans to implement in 2020 will result in estimated pre-tax annualized cost savings of approximately $11.0 million to $12.0 million, of which approximately $8.0 million to $9.0 million is related to the restructuring plan. The Company expects to begin realizing the savings from the reduction in force in the third quarter of 2020 and that it will incur approximately $1.5 million to $2.0 million in cash expenditures in connection with the restructuring plan, substantially all of which relates to severance costs.

Financial Outlook:

Marin is providing guidance for its third quarter of 2020 as follows:

Non-GAAP loss from operations excludes the effects of stock-based compensation, amortization of internally developed software and intangible assets, impairment of goodwill and long-lived assets, capitalization of internally developed software and non-recurring costs associated with restructurings and divestitures.

Additionally, the Company does not reconcile its forward-looking non-GAAP loss from operations, due to variability between revenues and non-cash items such as stock-based compensation. The GAAP loss from operations includes stock-based compensation expense, which is affected by hiring and retention needs, as well as the future price of Marin’s stock. As a result, a 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, amortization of internally developed software and intangible assets, impairment of goodwill and long-lived assets, non-cash expenses related to debt agreements, capitalization of internally developed software and non-recurring costs associated with restructurings and divestitures. Non-GAAP net loss per share is calculated as non-GAAP net loss divided by the weighted average shares outstanding.

Adjusted EBITDA. Marin defines Adjusted EBITDA as net loss, adjusted for stock-based compensation expense, depreciation, amortization of internally developed software and intangible assets, capitalization of internally developed software, impairment of goodwill and long-lived assets, benefit from or provision for income taxes, other income, net and non-recurring costs associated with restructurings and divestitures.

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.
