Item 3.01 Notice of Delisting or Failure to Satisfy a Continued Listing Rule or Standard; Transfer of Listing.

As previously reported, on April 16, 2025, Marin Software Incorporated, a Delaware corporation (the “Company”), received a notification letter (the “Initial Notice”) from the Listing Qualifications Department of The Nasdaq Stock Market LLC (“Nasdaq”) advising the Company that it was not in compliance with Nasdaq’s continued listing requirements under Nasdaq Listing Rule 5250(c)(1) (the “Rule”) as a result of its failure to timely file its Annual Report on Form 10-K for the fiscal year ended December 31, 2024 (the “Form 10-K”).

On May 21, 2025, the Company received an additional notification letter (the “Second Notice”) from Nasdaq advising the Company that it was not in compliance with Nasdaq’s continued listing requirements under the Rule as a result of its failure to timely file its Quarterly Report on Form 10-Q for the quarter ended March 31, 2025 (the “Form 10-Q”) and continued failure to file its Form 10-K, as previously communicated in the Initial Notice.

In response to the Initial Notice and the Second Notice, on June 16, 2025, the Company submitted a letter to Nasdaq requesting an exception to extend the Company’s listing on Nasdaq for 180 days, until October 13, 2025.

On June 17, 2025, the Company received a letter (the “Denial Letter”) from Nasdaq stating that Nasdaq had determined that the Company did not provide a definitive plan evidencing its ability to achieve compliance with the Rule, and as a result, (i) the Company’s request for continued listing on Nasdaq was denied; (ii) the Company’s securities will be delisted from Nasdaq; (ii) trading of the Company’s common stock will be suspended at the opening of business on June 26, 2025; and (iii) a Form 25-NSE will be filed with the Securities and Exchange Commission (the “SEC”), which will remove the Company’s securities from listing and registration on Nasdaq, unless the Company appeals these determinations.

The Company does not expect to appeal Nasdaq’s determinations and expects Nasdaq to file a Form 25-NSE (Notification of Removal from Listing) with the SEC to remove the Company’s common stock from listing and registration on Nasdaq.

Further, the Company does not currently intend to apply for its common stock to be traded on any of the markets operated by the OTC Markets Group Inc. due to the associated costs and in light of both the previously announced potential transaction the Company is currently exploring whereby a private equity firm would acquire substantially all of the assets of the Company, which may be through a voluntary reorganization transaction (the “Potential Transaction”), as well as the voluntary dissolution and liquidation of the Company (the “Dissolution”) that was previously approved by the Company’s stockholders. There can be no assurance that the Potential Transaction will be entered into or ultimately be successful, and the Company may abandon pursuing the Potential Transaction and instead pursue the Dissolution as previously described in the Company’s Definitive Proxy Statement on Schedule 14A filed with the SEC on May 7, 2025 (the “Proxy Statement”).

Once the Company’s common stock is delisted, the Company’s stockholders may find it difficult to obtain accurate quotations of the Company’s common stock, experience a lack of liquidity with difficulty finding buyers to purchase the stock, a lack of market makers to support the stock price, and the Company’s common stock is classified as a “penny stock” which requires brokers trading in the Company’s common stock to adhere to more stringent rules, which may result in a reduced level of trading activity in the secondary trading market for the Company’s common stock.

Item 8.01 Other Events

On June 20, 2025, the Company issued a press release regarding its receipt of the Denial Letter. A copy of the foregoing press release is attached as Exhibit 99.1 to this Current Report on Form 8-K (the “Current Report”) and is incorporated by reference herein.
