San Francisco, CA (August 8, 2019) – 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, 2019.

“Marin strengthened its balance sheet during the second quarter and continued to expand support for emerging channels such as Amazon, LinkedIn, and Apple Search Ads,” said Chris Lien, Chief Executive Officer of Marin Software. “We are also helping navigate significant industry changes such as Intelligent Tracking Prevention, so that advertisers can focus on growing their business through search, social and eCommerce advertising.”

Second Quarter 2019 Financial Updates:

●	Net revenues totaled $12.5 million, a year-over-year decrease of 12% when compared to $14.3 million in the second quarter of 2018.

●	GAAP loss from operations was ($4.5) million, resulting in a GAAP operating margin of (36%), as compared to a GAAP loss from operations of ($8.4) million and a GAAP operating margin of (59%) for the second quarter of 2018.

●	Non-GAAP loss from operations was ($2.6) million, resulting in a non-GAAP operating margin of (21%), as compared to a non-GAAP loss from operations of ($6.3) million and a non-GAAP operating margin of (44%) for the second quarter of 2018.

●	Cash, cash equivalents and restricted cash totaled $10.9 million as of June 30, 2019, as compared to $11.5 million as of December 31, 2018.

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.”

Financial Outlook:

Marin is providing guidance for its third quarter of 2019 as follows:

Forward-Looking Guidance

In millions

	Range of Estimate
	From			To
Three Months Ending September 30, 2019
Revenues, net	$	10.8		$	11.3
Non-GAAP loss from operations		(3.5	)		(3.0	)

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.

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. 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, provision for income taxes, other income, net and non-recurring costs associated with 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.

Prior to 2019, Marin also included deferred costs associated with contracts and the related amortization as an adjustment to net loss for the purposes of calculating the non-GAAP financial measures described above, but has updated its definition to no longer include those items. Non-GAAP financial measures for prior periods have been adjusted to conform to current period presentation.
