To be effective August 19, 2026
Aiming to meet the minimum bid price requirement for maintaining listing on Nasdaq
ATHENS, GREECE – August 17, 2026 – C3IS INC. (the “Company”) (Nasdaq: CISS) today announced that its board of directors has determined to effect a one-for-forty (1-for-40) reverse stock split of the Company’s common stock, par value $0.01 per share.
The reverse stock split will take effect at 11:59 pm Eastern Time on August 18, 2026, and the Company’s common stock will begin trading on a split-adjusted basis on The Nasdaq Capital Market (“Nasdaq”) as of the opening of trading on August 19, 2026. The CUSIP number of Y18284409 will be assigned to the Company’s common stock when the reverse stock split becomes effective.
When the reverse stock split becomes effective, every forty (40) of the Company’s issued shares of common stock will be combined into one issued share of common stock, without any change to the par value per share. This will reduce the number of outstanding shares of common stock from approximately 57.6 million shares to approximately 1.44 million shares. The Company’s outstanding warrants and Series A Convertible Preferred Stock will be proportionately adjusted to increase the exercise price and reduce the number of shares issuable upon exercise. With respect to the Company’s Class B Warrants and Class C Warrants, the exercise price and number of shares issuable upon exercise will be adjusted further in an adjustment period ending on the fifth trading day after the effective time of the reverse split pursuant to the terms of such warrants.
No fractional shares will be issued in connection with the reverse stock split. Stockholders who would otherwise hold a fraction of a share of common stock of the Company will receive a cash payment in lieu thereof at a price equal to that fraction of a share to which the stockholder would otherwise be entitled, multiplied by the closing price of the Company’s common stock on Nasdaq on August 18, 2026 (as adjusted for the reverse split).
Stockholders with shares held in book-entry form or through a bank, broker, or other nominee are not required to take any action and will see the consequence of the reverse stock split reflected in their accounts on or after August 19, 2026. Such beneficial holders may contact their bank, broker, or nominee for more information.
The reverse stock split ratio approved by the board of directors is within the range of ratios for a reverse stock split authorized by the stockholders of the Company.
The purpose of the reverse stock split is to increase the market price of the Company’s common stock. The Company believes that the reverse stock split will increase the market price for its common stock and allow it to satisfy the minimum bid price requirement for maintaining listing on Nasdaq.
