Sable Offshore Corp. 8-K

What Happened

• Sable Offshore Corp. announced via an 8-K filed December 23, 2025 that the U.S. Department of Transportation’s Pipeline and Hazardous Materials Safety Administration (PHMSA) notified the company on December 22, 2025 that it approved Sable’s Restart Plan for the Las Flores Pipeline System (Lines CA-324 and CA-325).
• The PHMSA approval letter is attached to the filing as Exhibit 99.1.

Key Details

• PHMSA approval date: December 22, 2025.
• 8-K filing date: December 23, 2025; signed by Gregory D. Patrinely, Executive Vice President and Chief Financial Officer.
• Approved assets: Las Flores Pipeline System — Line CA-324 and Line CA-325.
• Supporting document: PHMSA approval letter included as Exhibit 99.1 in the filing.

Why It Matters

• Regulatory approval of the Restart Plan is a required step before the company can resume operations of the specified pipeline segments; this is a material operational development.
• For investors, the approval could affect the company’s near-term operational status and potential revenue from the Las Flores system once any remaining conditions or activities needed for restart are completed.
• The 8-K provides the formal notice and the PHMSA letter for investors to review; any further updates about timing, conditions for restart, or operational milestones would be material and should be watched for in future filings.
