Sable Offshore Corp. (NYSE:SOC) disclosed that the SEC and federal prosecutors in New York have issued subpoenas for company documents regarding allegations that the company shared sensitive non-public information with select high-profile investors, including Phil Mickelson, while excluding others. The company faces potential civil and criminal penalties. SOC shares have dropped over 70% in the past six months and were trading down 8.88% at $8.22.

Sable Offshore's stock surged 30% following a December 31, 2025 U.S. Court of Appeals ruling that denied environmental groups' request to halt the Las Flores pipeline restart. The 9th Circuit decision, combined with a federal permit issued by PHMSA on December 22, allows the company to resume oil production from its Santa Ynez Unit facility, potentially generating 45,000 barrels per day. This removes the company's pre-revenue status and enables refinancing of its $900 million ExxonMobil loan at lower rates. Analysts project 60-70% upside potential, though execution risks and continued legal challenges remain.

Sable Offshore's stock plummeted 13.49% on December 26, 2025, after environmental groups including the Sierra Club filed a lawsuit to challenge a federal regulator's decision approving the restart of the Las Flores pipeline in California. The Department of Transportation's Pipeline and Hazardous Materials Safety Administration had ruled that the pipeline falls under federal rather than state oversight, but the lawsuit seeks an emergency stay to halt the restart. The pipeline has a troubled history, including a 2015 spill of over 100,000 gallons of oil.

Sable Offshore surged 36% on December 23, 2025, after federal regulators approved the restart of its Las Flores Pipeline System in California.
