Rubico Inc. is expanding its fleet by agreeing to buy 100% of an SPV that holds a shipbuilding contract for a 47,499 dwt ECO MR product/chemical tanker scheduled for delivery in 2029, for a purchase price of about $4.2 million.

A seven-year time charter, plus four one-year options with a major oil trader, provides potential gross revenue backlog of about $75 million.
Because the seller is a related party, the deal was approved by an independent board committee that obtained a fairness opinion. Rubico also created Series G Perpetual Convertible Preferred Shares, which may be issued as consideration, carry a 15% annual cash dividend on a $1,000 liquidation amount, are convertible into common shares at a formula-based price with a $0.60 floor, and grant 1,000 votes per share subject to a 19.99% voting cap. The company highlights that future use of equity lines, warrants, and Series E and G preferred shares could dilute existing shareholders and may discourage takeovers.
