SAN FRANCISCO–(BUSINESS WIRE)–Marin Software Incorporated (NASDAQ: MRIN), a leading provider of digital marketing software for performance-driven advertisers and agencies, announced that at its annual meeting of stockholders held today, stockholders voted to approve a proposal authorizing the Board of Directors to effect a reverse stock split of Marin’s outstanding shares of common stock at a ratio of not less than 1-for-4 and not more than 1-for-6, with the exact ratio to be set within that range at the discretion of the Board of Directors, and a proposal to reduce the number of authorized shares of Marin’s common stock from 142,857,143 to that number of shares equal to 142,857,143 multiplied by two times the stock split ratio. Marin’s Board of Directors has determined that the reverse stock split ratio will be 1-for-6 (the “Reverse Stock Split”).

Upon the effectiveness of the Reverse Stock Split, every 6 shares of Marin’s issued and outstanding common stock will be automatically combined and converted into one issued and outstanding share of common stock with any fractional amounts rounded down and paid in cash in lieu of the fractional amount. The Reverse Stock Split will reduce the number of shares of outstanding common stock from approximately 18.4 million to approximately 3.1 million. The Reverse Stock Split will not affect any stockholder’s ownership percentage of Marin’s common stock.

At the opening of trading on April 15, 2024, Marin’s common stock will continue to trade on the Nasdaq Capital Market under the symbol “MRIN,” but will be assigned a new CUSIP number (56804T 304) and will trade on a split-adjusted basis.

Broadridge Corporate Issuer Solutions, Inc., Marin’s transfer agent, will provide instructions to registered stockholders regarding the process for exchanging their stock certificates.
