Rubico’s board declared a stock dividend of 0.50 common shares for each common share outstanding. Shareholders of record at the close of business on September 28, 2026, are scheduled to receive the distribution on or about October 5, 2026. No fractional shares will be issued; resulting fractions will be paid in cash based on Rubico’s Nasdaq Capital Market closing price on the record date. Under the terms of the company’s outstanding warrants, the exercise price will be reduced by 33.33% and the number of shares issuable upon exercise will increase by 50% immediately after the record date. Nasdaq is expected to establish due-bill trading procedures, meaning market purchasers through the distribution date are expected to receive the stock dividend, while existing shareholders must hold their shares through October 5. Rubico’s shares are expected to begin trading on a stock dividend-adjusted basis on or about October 6.
