(NASDAQ:RUBI) (the "Company" or "Rubico"), a global provider of shipping transportation services specializing in the ownership of vessels, announced today that, pursuant to its previously announced letter of intent (the "LOI"), it has entered into a share purchase agreement (the "SPA") with Top Ships Inc., a related party controlled by Rubico's controlling shareholder, to purchase the shares of a company (the "SPV") that is party to a shipbuilding contract with Guangzhou Shipyard International Company Limited and China Shipbuilding Trading Co., Ltd. for the construction of a 47,499 dwt chemical/product oil carrier (the "Newbuilding MR Tanker"). The Newbuilding MR Tanker is scheduled for delivery in the second quarter of 2029.

The SPV has also entered into a sale and leaseback financing agreement with a major Chinese leasing company for an amount of 85% of the installment payments under the shipbuilding contract. The purchase price under the shipbuilding contract, payable in installments up to the delivery of the vessel, is $45.2 million out of which $6.8 million has already been settled. The financing bears an interest rate of Term SOFR plus a margin of 1.80%. Under the financing, following the delivery of the vessel, the Company will pay quarterly installments of $0.5 million over a period of 10 years with a balloon payment of $18.2 million payable together with the last installment. Top Ships Inc. and the Company will provide corporate guarantees in favor of the leasing company.

The aggregate purchase price for 100% of the shares of the SPV is approximately $6.5 million (the "Consideration"), payable in full at closing. The advance cash payment of $0.3 million of the LOI will be credited against the Consideration. The transaction is expected to close by September 30, 2026, subject to customary closing conditions.
