Sable Offshore Corp. Investor Presentation November 2025

2 FORWARD LOOKING STATEMENTS The information in this presentation includes “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995. When used in this presentation, the words “could,” “should,” “will,” “may,” “believe,” “anticipate,” “intend,” “estimate,” “expect,” “project,” “continue,” “plan,” “forecast,” “predict,” “potential,” “future,” “outlook,” and “target,” the negative of such terms and other similar expressions are intended to identify forward-looking statements, although not all forward-looking statements will contain such identifying words. These statements are based on the current beliefs and expectations of Sable’s management and are subject to significant risks and uncertainties. Actual results may differ materially from those described in the forward-looking statements. Factors that could cause Sable’s actual results to differ materially from those described in the forward-looking statements include: the ability to recommence production of the Santa Ynez Unit assets including the implementation of an offshore storage and treating vessel (“OS&T”) strategy, bringing oil to market, and the cost and time required therefor, and production levels once recommenced; availability of future financing; our financial performance, including liquidity estimates; production levels once recommenced; commodity price volatility; low prices for oil and/or natural gas; global economic conditions and inflation; increased operating costs; lack of availability of drilling and production equipment, supplies, services and qualified personnel; processing volumes and pipeline throughput; geographical concentration of operations; environmental and weather risks; regulatory changes and uncertainties; the uncertainty inherent in estimating oil and natural gas resources and in projecting future rates of production; reductions in cash flow and lack of access to capital; restrictions in existing or future debt agreements or structured or other financing arrangements; managing growth and integration of acquisitions, and failure to realize the expected value of acquisitions; the ability to recognize the anticipated benefits of the business combination; developments relating to our competitors and our industry; litigation, complaints and/or adverse publicity; privacy and data protection laws, privacy or data breaches, or loss of data; our ability to comply with laws and regulations applicable to our business; and other one-time events and other factors that can be found in Sable’s Annual Report on Form 10-K for the year ended December 31, 2024, and any subsequent Quarterly Report on Form 10-Q or Current Report on Form 8-K, which are filed with the Securities and Exchange Commission and are available on Sable’s website (www.sableoffshore.com) and on the Securities and Exchange Commission’s website (www.sec.gov). Except as required by applicable law, Sable undertakes no obligation to publicly release the result of any revisions to these forward-looking statements to reflect the impact of events or circumstances that may arise after the date of this presentation. DISCLAIMER The Santa Ynez Unit assets discussed in this presentation restarted production in May 2025 and have not sold commercial quantities of hydrocarbons since such Santa Ynez Unit assets were shut in during June of 2015 when the only Onshore Pipeline transporting hydrocarbons produced from such Santa Ynez Unit assets to market ceased transportation. Since the May 2025 production restart, the oil produced has been transported via pipeline to storage tanks onshore at Sable’s Las Flores Canyon processing facility where it is being stored pending resumption of petroleum transportation through the Onshore Pipeline. There can be no assurance that the necessary approvals will be obtained that would allow the Onshore Pipeline to recommence transportation or the contemplated use of an Offshore Storage and Treating Vessel that would allow the Santa Ynez Unit assets to recommence sales. OIL AND GAS RESOURCE INFORMATION This presentation includes information regarding estimates of oil and natural gas resources attributable to the Santa Ynez Unit. None of the oil and gas resources attributable to the Santa Ynez Unit are currently classifiable as proved or other reserves because, since the cessation of operations on the pipeline transporting production from the assets, there has been no means to deliver production from the assets to market. Sable has obtained a report (the “NSAI Report”) from Netherland, Sewell & Associates, Inc. (“NSAI”), independent petroleum consultants, with respect to the net estimated contingent resources attributable to the acquired assets and the related pre-tax discounted (at 10%) future net contingent cash flow from such contingent resources, as of December 31, 2021, based on 12-month unweighted arithmetic average of the first-day-of-the-month prices for each month in the period from January to December 2021. As defined by the Society of Petroleum Engineers and used in the NSAI Report, “contingent resources” are those quantities of petroleum which are estimated, on a given date, to be potentially recoverable from known accumulations, but which are not currently considered to be commercially recoverable. Contingent resource estimates may be characterized further as 1C (low estimate), 2C (best estimate) and 3C (high estimate). The contingent resources reflected in the NSAI Report are, as stated in the report, category 1C (low estimate). The NSAI Report states that the estimates included in the report are contingent on (1) approval from federal, state and local regulators to restart production, (2) reestablishment of oil transportation systems to deliver production to market, and (3) commitment to restart the wells and facilities. The NSAI Report states that, if these contingencies are successfully addressed, some portion of the contingent resources estimated in the report may be reclassified as reserves but notes that the estimates have not been risked to account for the possibility that the contingencies are not successfully addressed. The NSAI Report does not address (1) the portion of the contingent resources that could be reclassified as reserves if the contingencies are successfully addressed or (2) whether or to what extent any of the contingent resources that could be so reclassified would be classified as proved, probable or possible reserves. As defined in the Society of Petroleum Engineers’ Petroleum Resources Management System (“PRMS”), "best estimate" is the most realistic assessment of recoverable quantities if only a single result were reported. There is at least a 50% probability that the quantities actually recovered will equal or exceed the “best estimate.” As defined in the PRMS, "low estimate" is a conservative estimate of the quantity that will actually be recovered from the accumulation by a project. There is at least a 90% probability that the quantities actually recovered will equal or exceed the “low estimate.” The resource estimates and related future cash flow information included in this presentation reflect management's estimates, based in part on the contingent resources estimated in the NSAI Report and supplemented by management's own estimates of contingent resources attributable to the acquired assets and using the pricing and other assumptions noted in this presentation, of the contingent resources and cash flow that may have been attributable to the acquired assets if the contingencies had been addressed successfully on the date as of which the information is presented. Resource engineering is a process of estimating underground accumulations of hydrocarbons that cannot be measured in an exact way. The accuracy of any resource or reserve estimate depends on the quality of available data, the interpretation of such data, and price and cost assumptions made by reserve engineers. In addition, the results of drilling, testing, and production activities may justify revisions of estimates that were made previously. If significant, such revisions could impact the combined company’s strategy and change the schedule of any production and development drilling. Accordingly, resource estimates may differ significantly from the quantities of oil and natural gas that are ultimately recovered. USE OF PROJECTIONS AND ESTIMATES This presentation contains financial projections and estimates for Sable, including with respect to its future capital expenditures, initial timing and production estimates and future cash costs. Sable’s auditors have not audited, reviewed, compiled or performed any procedures with respect to the projections and estimates for the purpose of their inclusion in this presentation, and, accordingly, no such auditors have expressed an opinion or provided any other form of assurance with respect thereto for the purpose of this presentation. These projections and estimates are for illustrative purposes only and should not be relied upon as being necessarily indicative of future results. The assumptions and estimates underlying the projected information are inherently uncertain and are subject to a wide variety of significant business, regulatory, economic and competitive risks and uncertainties that could cause actual results to differ materially from those contained in the projected information. Even if the assumptions and estimates are correct, projections and estimates are inherently uncertain due to a number of factors outside Sable’s control. Accordingly, there can be no assurance that the projected results are indicative of Sable’s future performance or that actual results will not differ materially from those presented in the projected information. Inclusion of the projected information in this presentation should not be regarded as a representation by any person, including, without limitation, Sable, that the results contained in the projected information will be achieved.

(3) 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 onshore oil and natural gas processing facility 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(3)  Sable is evaluating and pursuing an OS&T as an offtake alternative to LFC (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). (3) SYU-produced oil is being held in the Company’s storage tanks at LFC while Sable awaits regulatory approvals to resume petroleum transportation through the Las Flores Pipeline System as outlined in the Consent Decree. Alternatively, Sable is evaluating and pursuing installing Offshore Storage & Treating vessel to process oil and gas production.
