Exhibit 99.1 • Resumed oil production from Platform Heritage in early April 2026. Operational Updates • July 2026 preliminary oil sales estimate of approximately 38,000 gross barrels of oil per day. August 2026 oil sales average to date is approximately 42,000 gross barrels of oil per day through August 9th. • In July 2026, an average of approximately 47 wells at Platforms Harmony and Heritage were online, producing an average of approximately 721 gross barrels of oil per day per well. Sable expects to bring all 77 production wells on these two platforms online during the third quarter of 2026 and expects Platform Hondo to come online in September 2026. • Wireline campaign for Perforation Additions (“Perf Adds”) and producing well optimization at Platform Harmony commenced in August 2026. • Five completed Perf Adds forecasted to produce an incremental 600 estimated gross barrels of oil per day, each, are expected to come online at Platform Hondo along with the restart of the platform in September 2026. • An additional four Perf Adds at Platform Hondo forecasted to produce an incremental estimated 600 gross barrels of oil per day are planned for completion and to be brought online in early Q4 2026. Midstream and Brent Crude Oil Marketing Update • Due to the California regulatory environment, local refineries were not able to plan in advance for SYU first sales and ultimately were forced to displace various imported cargos in the second quarter. As a result, Sable incurred $18.5 million of non-recurring demurrage charges throughout the quarter, recognized in operational expenses. • The sudden supply influx of Pacific Outer Continental Shelf (“Pacific OCS”) crude has forced refiners to temporarily limit throughput of Pacific OCS crude and charge quality deducts for sulfur content and other items. • Platform Hondo is expected to produce lower sulfur content oil, which should bring field-wide sulfur content to normal levels upon planned restart in September 2026. • Chemical-based solutions are expected to be tested in Q4 2026 that would potentially sweeten SYU crude production and lower sulfur content with full implementation anticipated in 2027. • Starting in July 2026, Sable was temporarily constrained to a maximum of 40,000 average gross barrels of oil per day of oil sales throughput by downstream partners. We expect this short-term constraint to be alleviated starting in the back half of August. • California refineries are expected to adjust their crude oil supply slate starting in September 2026 to begin accepting more Pacific OCS barrels from the SYU and less imported barrels, alleviating the SYU throughput constraint altogether. • Sable is also in active negotiations to implement waterborne crude oil marketing solutions from existing marine terminals in the Los Angeles area in the near-term in order to improve marketing optionality. • Additionally, the pending acquisition of the Crimson Utilities (San Pablo Bay Pipeline) pipeline network by a third party could provide further relief and marketing optionality to California oil producers with access to the San Francisco refinery market once that pipeline potentially restarts operations. 2

Exhibit 99.1 Guidance • Reduced 2H 2026E midpoint capex by 41% to $85 million. Planned capex reductions are intended to optimize cash flow and accelerate debt amortization. • Increased 2027 expected oil ratio to approximately 100% from prior midpoint of 91% due to the deferral of POPCO gas plant capital items and stronger than anticipated oil cut from producing wells. • In light of the short-term midstream throughput constraints and widened differentials, Sable’s 2H 2026 capex budget is focused on maintaining asset integrity, maximizing midstream throughput, executing high return Perf Adds, and well optimization work. • FY 2027E guidance reflects the expected normalization of fully ramped, post-restart operations. 2H 2026E FY 2027E Sales Gross Average Daily Sales (Boe/d) 47,500‒ 52,500 50,000‒ 55,000 Working Interest / Net Revenue Interest (%) 83.6% 83.6% Net Average Daily Sales (Boe/d) 40,000‒ 45,000 42,500‒ 47,500 % Oil ~100.0% ~100.0% Estimated Marketing and GP&T Deduct ($/Bbl) $24.00‒ $28.00 $21.00‒ $25.00 Cash Costs ($ / Net Boe) Lease Operating Expense $17.00‒ $21.00 $9.00‒ $12.00 Cash General & Administrative $6.00‒ $9.00 $3.50‒ $6.50 Severance & Ad Valorem Taxes (% of Revenue) 0.5 % ‒ 1.0% 0.5 % ‒ 1.0% Capital Expenditures ($MM) Total Capex $75‒ $95 $80‒ $100 Note: No benefits from waterborne marketing solutions, chemical treatments, and broader California infrastructure improvements assumed in guidance.

We are encouraged by the productivity of the wells at the SYU with their higher than expected production with minimal to no observable decline.” He continued, “Through the various solutions we have identified, we look forward to working with our midstream and downstream partners to maximize the amount of domestic crude oil from the SYU getting to market for the benefit of California consumers and the U.S. Military and its allies globally.” About Sable Sable Offshore Corp. is an independent oil and gas company, headquartered in Houston, Texas, focused on responsibly developing the Santa Ynez Unit in federal waters offshore California.
