Rubico Announces Record Date of Monday, September 28 and Ex-Dividend Date of Tuesday, October 6 for Previously-Announced 0.50 Common Shares Per Common Share Stock Dividend

ATHENS, Greece, Sept. 25, 2026 (GLOBE NEWSWIRE) -- Rubico Inc. (Nasdaq: RUBI) (“Rubico,” or the “Company”), a global provider of shipping transportation services specializing in the ownership of vessels, announces that, in relation to the previously announced stock dividend of 0.50 common shares for each common share outstanding (the “Stock Dividend”), the Nasdaq Capital Market (“Nasdaq”) has determined that the ex-dividend date will be October 6, 2026. The Stock Dividend will be distributed on or about October 5, 2026 (the “Distribution Date”) to shareholders of record as of the close of business on September 28, 2026. No fractional shares will be issued in connection with the Stock Dividend; any fractional shares resulting from the Stock Dividend will be paid in cash based on the closing price of the Company’s common shares on Nasdaq on September 28, 2026.

As a result of “due bill” trading procedures expected to be established by Nasdaq, Rubico common shares are expected to trade with due bills from September 28, 2026 through and including the Distribution Date. Accordingly, holders of Rubico common shares as of September 28, 2026 will need to hold such shares through and including the Distribution Date in order to receive the Stock Dividend.

This would mean that holders who purchase Rubico common shares during the due bill period (even if the trades are to be settled after the due bill period) will be entitled to receive the Stock Dividend with respect to those shares. Conversely, sellers who sell Rubico common shares during the due bill period (even if the trades are to be settled after the due bill period) will not be entitled to the Stock Dividend with respect to those shares.

Due bills obligate a seller of securities to deliver the distribution payable on such securities to the buyer. The due bill obligations are customarily settled between the brokers representing buyers and sellers of the securities. The Company has no obligation for either the amount of the due bill or the processing of the due bill. Buyers and sellers of Rubico’s common shares should consult their brokers before trading to ensure they understand the effect of Nasdaq’s due bill procedures.
