Disclaimers

The Santa Ynez Unit assets discussed in this press release restarted production in May 2025 and have not sold commercial quantities of hydrocarbons since such Santa Ynez Unit assets were shut in during June of 2015 when the only onshore pipeline transporting hydrocarbons produced from such Santa Ynez Unit assets to market ceased transportation. Since the May 2025 production restart, the oil produced has been transported via pipeline to storage tanks onshore at Sable’s Las Flores Canyon processing facility where it is being stored pending resumed petroleum transportation through the Las Flores Pipeline System. There can be no assurance that the necessary approvals will be obtained that would allow the Las Flores Pipeline System to recommence transportation or the contemplated use of an Offshore Storage and Treating Vessel that would allow the Santa Ynez Unit assets to recommence sales.
