The Marshall Islands is the principal flag of registry of the Company’s vessels. The Company’s business is currently organized into two reportable segments: Crude Tankers and Product Carriers. The crude oil fleet is comprised of most major crude oil vessel classes. The products fleet transports refined petroleum product cargoes from refineries to consuming markets characterized by both long and short-haul routes.

As of December 31, 2025, the Company owned or operated a fleet of 70 wholly-owned or lease financed and time chartered-in oceangoing vessels. In addition to its operating fleet, four LR1 newbuilds are scheduled for delivery to the Company by third quarter of 2026, bringing the total operating and newbuild fleet to 74 vessels as of December 31, 2025. The Company’s operating fleet list excludes vessels chartered-in where the duration of the charter was one year or less at inception. Vessels chartered-in may be bareboat charters or time charters. Under either a bareboat charter or time charter, a customer pays a daily or monthly rate for a fixed period of time for use of the vessel. Under a bareboat charter, the customer pays all costs of operating the vessel, including voyage expenses, such as fuel, canal tolls and port charges, and vessel expenses such as crew costs, vessel stores and supplies, lubricating oils, maintenance and repair, insurance and communications associated with operating the vessel. Under a time charter, the customer pays all voyage expenses and the shipowner pays all vessel expenses.
