Rockhopper Exploration plc (AIM: RKH) has entered into a subscription agreement to acquire its 35% participating interest in the OSX-1 floating production, storage and offloading vessel, which is planned for use at the Sea Lion project in the North Falkland Basin.
The company will subscribe for US$44 million of ordinary shares in a newly incorporated special-purpose vehicle that owns the FPSO.
The investment will be funded entirely from Rockhopper’s existing cash resources.
The US$44 million commitment represents Rockhopper’s 35% share of the previously disclosed total acquisition cost of approximately US$125 million for the OSX-1 vessel.
The FPSO is intended to support the accelerated development of the Central Development Area at Sea Lion, making the transaction a significant piece of project infrastructure rather than a financial investment in an unrelated asset.
The special-purpose vehicle has been established specifically to own the FPSO and has no material trading history or other business activities.
That means Rockhopper’s economic exposure is directly linked to the ownership, holding and eventual deployment of the vessel.
Until the FPSO enters operational service, Rockhopper expects to incur net holding costs attributable to its 35% interest of approximately US$1.4 million per year.
For investors, the transaction removes another element of uncertainty around a critical piece of Sea Lion infrastructure and confirms that Rockhopper has sufficient cash to fund its share of the acquisition without an immediate equity raise.
However, the US$44 million outlay also represents a material deployment of cash ahead of first production, while the additional US$1.4 million annual holding cost will continue until the vessel is brought into productive use.
The key issue is therefore no longer simply whether Rockhopper will participate in the FPSO acquisition, but how quickly OSX-1 can be prepared, integrated into the wider Sea Lion development and converted from a cash-consuming asset into productive infrastructure.
For investors, the next important milestones remain progress on the wider Sea Lion development programme, modification and deployment of the FPSO, project financing and confirmation of the timetable towards first oil.
