On December 29, 2025, MediciNova, Inc. (the “Company”) entered into an equity distribution agreement with Lucid Capital Markets, LLC (“Agent”) to sell shares of the Company’s common stock, par value $0.001 per share (the “Common Stock”), from time to time through the Agent, acting as sales agent, having a maximum aggregate offering price of $50,000,000 (the “Sales Agreement”).

Upon delivery of a placement notice and subject to the terms and conditions of the Sales Agreement, the Agent may sell the common stock by methods deemed to be an “at the market offering” as defined in Rule 415(a)(4) promulgated under the Securities Act of 1933, as amended (the “Securities Act”).

The Company will designate the maximum amount of common stock to be sold through the Agent in any placement under the Sales Agreement. Subject to the terms and conditions of the Sales Agreement, the Agent has agreed to use its commercially reasonable efforts to sell on the Company’s behalf all of the shares of Common Stock requested to be sold by the Company. The Company may instruct the Agent not to sell common stock if the sales cannot be effected at or above a price designated by the Company in a placement notice. The Company or the Agent may suspend the offering of Common Stock pursuant to the Sales Agreement upon proper notice to the other party. The Company and the Agent each have the right, by giving written notice as specified in the Sales Agreement, to terminate the Sales Agreement in each party’s sole discretion at any time.

The Sales Agreement provides that the Agent will be entitled to aggregate compensation for its services of 3.0% of the gross sales price per share of all shares sold through the Agent under the Sales Agreement. The Company has no obligation to sell any shares under the Sales Agreement. The Company has agreed in the Sales Agreement to provide indemnification and contribution to the Agent against certain liabilities, including liabilities under the Securities Act. In addition, the Company has agreed to reimburse certain legal expenses incurred by the Agent in connection with execution of the Sales Agreement in an amount up to $75,000, in addition to certain ongoing legal expenses.
