Ocho Investments LLC 1401 Lavaca Street Unit 40912 Austin, TX 78701 April 17, 2025 Dear Fellow Digimarc Corporation Shareholders: Ocho Investments LLC (“Ocho”) has been a sizable shareholder of Digimarc Corporation (“Digimarc”, “DMRC”, or “the Company”) since late 2020. In the past two months, Ocho increased its position and currently owns 1,115,000 shares, which represent 5.2% of the Company. In connection with the Company’s upcoming Annual Meeting scheduled for May 7, 2025, Ocho will:

| • |     | Vote “WITHHOLD” on Riley McCormack, who as CEO is responsible for the Company’s poor 
 performance and destruction of shareholder value                                     |

| • |     | “VOTE NO” on the Company’s                                                                                                                                       
 say-on-pay (Proposal No. 3 on your proxy card); this incentive plan has created misalignment between management versus shareholders in that executives were well 
 compensated while shareholders lost significant value                                                                                                            |
