Sable Resumes Oil Flow as Ordered by the Federal DPA with Expected Gross Oil Rate of 50,000 Bbls/d and Expects First Sales by April 1, 2026

Sable Offshore Corp. ("Sable," or the "Company") (NYSE:SOC) today announced that on March 14, 2026, the Company resumed the transportation of hydrocarbons (oil) produced at the Santa Ynez Unit ("SYU") through the federally regulated and approved to operate Santa Ynez Pipeline System ("SYPS") from Las Flores Canyon ("LFC") to Pentland Station at the direction of the United States Secretary of Energy, Chris Wright.

On March 13, 2026, President of the United States, Donald J. Trump, signed an Executive Order to, among other things, delegate certain authorities under the Defense Production Act of 1950 ("DPA") to the United States Secretary of Energy. Subsequently on March 13, 2026, the United States Secretary of Energy, Chris Wright, issued an order to Sable invoking the DPA (the "DPA Order") to immediately prioritize and allocate pipeline transportation services for hydrocarbons from the SYU through the SYPS in order to address the energy scarcity and supply disruption risks caused by California policies that have left the region and U.S. military forces dependent on foreign oil. Sable immediately complied with this federal DPA Order and began shipping hydrocarbons from LFC to Pentland Station on March 14, 2026 with federal safety regulators present in observance.

As stated in the DPA Order, all federally produced barrels from the SYU must flow through the SYPS, up to the existing pipeline capacity of 200,000 Bbls/d. Sable completed its onshore anomaly repair program and hydrotested all segments of the SYPS consistent with applicable requirements as of May 2025.

Prior to resuming hydrocarbon transportation from LFC to Sable's sales point at Pentland Station, Sable had approximately 540,000 barrels of processed crude oil in storage at LFC, representing more than the line fill volume for the SYPS between LFC and Pentland Station. Sable is fully staffed and will continue to implement the conditions of the Emergency Special Permit previously issued by the United States Department of Transportation, Pipeline and Hazardous Materials Safety Administration.

Sable is currently producing hydrocarbons from its Platform Harmony at the SYU and our wells continue to perform as expected. Production ramp-up is anticipated to proceed with full production resumption at Platforms Harmony and Heritage this month, in March 2026, and Platform Hondo in June 2026. The Company plans to commence first sales by April 1, 2026 at an expected gross oil rate of 50,000 Bbls/d.

Also on March 13, 2026, Sable and Pacific Pipeline Company ("PPC") sued California Department of Parks and Recreation ("State Parks") in a lawsuit styled Sable Offshore Corp. and Pacific Pipeline Company, Plaintiffs v. Armando Quitero, in his official capacity as Director of the California Department of Parks and Recreation, Defendant, Case, No. 2:26-cv-02739 in the United States District Court for the Central District of California. The lawsuit requests declaratory relief to confirm Sable and PPC's rights (and their ability to fulfill their obligations) under the DPA Order. Subsequently, on March 14, 2026, State Parks sent a letter to Sable contesting Sable's rights under the DPA Order.

As previously stated, Sable is pursuing all financing options, including federal credit support. The Company plans to refinance its Senior Secured Term Loan, deploy its commodity hedging program, and evaluate shareholder return options shortly after commencing first sales.

"Sable Offshore is putting California consumers first by increasing domestic supply of crude oil into the California market by approximately 17% and we look forward to continuing to execute as so ordered by the Defense Production Act executed on March 13, 2026," said Jim Flores, Sable's Chairman and Chief Executive Officer. Flores continued, "We look forward to working closely with the Department of Energy in fully complying with the DPA and working with the Trump administration to take all necessary steps to deliver the energy necessary for the security and defense of the country."
