Key Financial Metrics and Transaction Details
- Acquisition Cost: Approximately $6.5 million for 100% of the shares of Roman Shark V Inc. (the SPV).
- Payment Terms: Payable by September 30, 2026. A $0.3 million advance is credited against the total. The balance may be paid in cash or newly-issued Series G Preferred Shares.
- Financing Structure: An 85% sale and leaseback financing agreement covers pre-delivery installments totaling $45.2 million ($6.8 million already settled). The effective interest rate is Term SOFR plus 1.80%.
- Debt Obligations: Post-delivery, the Company will make quarterly payments of $0.5 million over 10 years, with a balloon payment of $18.2 million due at maturity.
- Revenue Backlog: The vessel has a secured time charter for 7 years (with a 4-year extension option), generating a potential gross revenue backlog of approximately $75.4 million.
Material Changes and Unusual Items
The filing does not provide comparative financial statements (revenue, profit, or cash flow) for the period. The material change is the execution of the Share Purchase Agreement (SPA) on July 27, 2026, to acquire the SPV holding the rights to a 47,499 dwt chemical/product oil carrier scheduled for delivery in Q2 2029.
A "Cash Sweep" provision mandates that 100% of net cash proceeds from any equity financing prior to closing must be applied to the purchase price, unless the Seller waives this requirement.
Outlook, Risks, and Management Commentary
Management views this transaction as a strategic expansion of the fleet with a long-term revenue anchor. The transaction was approved by a special committee of independent directors and supported by an independent fairness opinion.
Risks and Contingencies:
- Financing Risk: The transaction relies on the definitive sale and leaseback financing agreement with ABC Financial Leasing Co., Ltd.
- Equity Dilution: The Company may issue Series G Preferred Shares to settle the purchase price.
- Capital Constraints: The Cash Sweep provision restricts the use of future equity raise proceeds for other corporate purposes prior to closing.
