3 Sable’s premier offshore asset is unleashed following the Defense Production Act Order Sable Offshore Corp. (NYSE: SOC) Santa Ynez Unit LFC Midstream Processing Facilities United States Department of Energy invoked the Defense Production Act ordering Sable to bring its resource to market  First sales from the Santa Ynez Unit (“SYU”) through the Santa Ynez Pipeline System (“SYPS”) achieved in March 2026  Three offshore platforms located in federal waters north of Santa Barbara, California  Wholly owned onshore midstream processing facilities at Las Flores Canyon (“LFC”)  >100 identified infill drilling and step-out opportunities, along with low-cost production optimization operations on existing wellbores High Quality Asset Unleashed Sable is well-qualified to operate the SYU and the SYPS  Exemplary track record of operating safely in California and offshore(1)  Demonstrated expertise via numerous awards from state and federal agencies(1)  Reviving premier offshore asset through close coordination with federal regulatory agencies Proven Operators with Regulatory Expertise (1) While at Plains Exploration & Production, current Sable management team operated platforms included Irene at Point Pedernales and Hidalgo, Harvest and Hermosa at Point Arguello.

4 SYU History Premier offshore project developed by Exxon over 40+ years  Discovered in 1968, over the course of 14 years Exxon consolidated more than a dozen offshore federal oil leases into a streamlined production unit known as SYU ─ SYU construction began in 1976 with Platform Hondo, with first production in 1981, followed by Platform Harmony and Platform Heritage (both online in 1994); both Harmony and Heritage have dedicated rigs for future development. Production was initially processed in federal waters in an OS&T from 1981 to 1994. ─ SYU includes 112 wells (90 producers, 12 injectors, 10 idle); sizable inventory of infill drilling and additional step-out drilling opportunities(1) ─ Platforms located 5 to 9 miles offshore Santa Barbara County in shallow water depths of 900-1,200’(2) SYU Development Background  Wholly owned midstream processing facilities at Las Flores Canyon (not visible from highway)  Shut in from June 2015 to May 2025 due to pipeline issue (Plains All- American Pipeline (“AAPL”) operated) ─ Production at all Exxon platforms and facilities was safely suspended. SYU was placed into a preserved state with regular inspections and maintenance ─ AAPL received Consent Decree and began work to resume petroleum transportation ─ Exxon acquired pipeline from AAPL  Sable restarted production at SYU Platform Harmony in May 2025 and began flowing production to Las Flores Canyon  Oil sales resumed through the SYPS in March 2026 following the Defense Production Act Order (1) Sable management have identified >100 infill drilling and step-out opportunities. (2) Primary Reservoir: Miocene Monterey formation (Sour low-gravity oil (4-26 API); Secondary Reservoirs: Oligocene and Eocene oil/gas sandstone (Sweet high-gravity oil (35 API).

(1) 1.5 MMBbl/d of California petroleum consumption per EIA. (2) List of countries that import oil into California is illustrative and not comprehensive. Commentary • Policy decisions have caused energy infrastructure closures and production decreases across all major segments: exploration & production, midstream transport, and refining and marketing • Given the absence of domestic energy supply, California has relied on foreign nations to import the required oil supply to meet the 1.5 MMBbl/d of demand(1) • California is in desperate need of increased local oil output, but a decades-long underinvestment in the supply chain due to the regulatory environment offers very little opportunity for immediate solutions outside of Sable • California consumers and the 40+ United States Military installations in state are vulnerable Reliance on Foreign Imports Crude Oil Production Shortfall – 500 1,000 1,500 2,000 2,500 – 10 20 30 40 50 1982 1991 1999 2008 2016 2025 O pe ra tin g R ef in in g C ap ac ity (M B bl /d ) # of O pe ra tin g R ef in er ie s # of Operating Refineries Operating Refining Capacity (MBbl/d) (66%) Decrease (27%) Decrease – 200 400 600 800 1,000 1,200 1982 1989 1996 2003 2010 2017 2025 California Crude Oil Production (MBbl/d) (75%) Decrease 23% 16% 61% 2025 Source of CA Oil Supply California Alaska Foreign –% 20% 40% 60% 80% 100% 1982 1989 1996 2003 2010 2017 2025 Source of California Oil Supply (%) California Alaska Foreign (2) Middle East: • Saudi Arabia • Iraq South America: • Ecuador • Brazil • Colombia (2)

13 Sable Supports California Consumers and US Warfighters Newsom administration analysis states a need for 125MM barrels of oil produced locally to mitigate crisis California Crude Oil Production Forecast (MMBbl/yr) Source: EIA, CalGEM presentation to the chairs of the Natural Resources, Transportation, and Utilities and Energy Committees of the California State Assembly on August 20, 2025. Note: CalGEM presentation replicated to best extent possible, values are estimates. 2026 – 2028 California onshore production is Sable’s internally estimated California onshore production based on operator commentary in public disclosures and sell-side equity research analysis. Commentary • California’s stated goal is to produce 125MM barrels of oil per year locally to stabilize its refinery complex. • Even with potential SB-237 policy impacts, California cannot achieve the Newsom administration’s target without the SYU. • Sable’s SYU barrels are the only solution to California’s current energy crisis and buffer against a policy driven shortage of gasoline and aviation fuels, critical to West Coast and Pacific U.S. military supply lines. • SYU production is providing a real and immediate supply increase to California consumers and the U.S. military. 80 90 100 110 120 130 140 2026 2027 2028 Ca lif or ni a Cr ud e O il Pr od uc tio n (M M Bb l/y r) SB-237 Effective – 1/1/26 125 MMBbl/yr Target +23 MM Bbls/Year from SYU Projected State Production, Assuming No SB-237 Policy Impact Projected State Production, with SB-237 Policy Impact Projected State Production, with SB-237 Policy Impact and SYU Online
