Rubico Inc., a global provider of shipping transportation services specializing in the ownership of vessels, estimated its net asset value (NAV) at $183.1 million as of June 30, 2026. This figure represents a 94% increase from the previous NAV reported on March 2, 2026. The surge in valuation is attributed to updated charter free vessel value estimates from third-party international brokers, alongside considerations for outstanding debt and cash.

The company’s management calculated the NAV based on the number of common shares currently outstanding. On a basic basis, the NAV stands at $300.26 per common share. On a fully diluted basis, which assumes the exercise of all 669,193 outstanding warrants and the conversion of all the Series G Convertible Preferred Shares, the NAV is $72.22 per common share.

Rubico Inc. has expanded its fleet and secured future cash flows through the acquisition of a newbuilding MR tanker, increasing its total potential gross revenue backlog by 33% to approximately $304.6 million. The company entered into a share purchase agreement with Top Ships Inc. to purchase 100% of the shares of a special purpose vehicle (SPV) that holds a shipbuilding contract with Guangzhou Shipyard International Company Limited and China Shipbuilding Trading Co., Ltd. The aggregate purchase price is approximately $6.25 million, payable in full at closing, which is expected by September 30, 2026.

The 47,499 dwt chemical/product oil carrier is scheduled for delivery in the third quarter of 2029. The SPV has secured time charter employment with a major oil trader for a firm duration of seven years, with an option to extend for four additional years. This specific contract contributes about $75.4 million to the potential gross revenue backlog. Including this new vessel, the total potential gross revenue backlog from Rubico's two newbuilding MR tankers rises to approximately $151.0 million.

Financing Structure

The SPV has entered into a sale and leaseback financing agreement with a major Chinese leasing company for 85% of the installment payments under the shipbuilding contract. The purchase price for the vessel is $45.2 million, with $6.8 million already paid. The financing carries an interest rate of Term SOFR plus a margin of 1.80%. Post-delivery, Rubico will pay quarterly installments of $0.5 million over 10 years, concluding with a balloon payment of $18.2 million. Top Ships Inc. and Rubico will provide corporate guarantees to the leasing company.

Corporate Governance and Financials

A special committee of independent and disinterested members of Rubico's board of directors approved the acquisition, obtaining a fairness opinion from an independent financial advisor. Kalliopi Ornithopoulou, President, Chairwoman & Chief Executive Officer, highlighted that the acquisition aligns with the strategy of redeploying capital into the core tanker business. She also referenced the company's 2025 financial results, published on March 23, 2026, which reported a net income of $2.6 million, total assets of $134.1 million, and stockholders’ equity of $45.8 million.
