Table V Proved Reserve Quantity Information*

Summary of Net Oil and Gas Reserves

• Reserve quantities include natural gas projected to be consumed in operations of 2,634, 2,462 and 2,655 billions of cubic feet and equivalent synthetic oil projected to be consumed in operations of 0, 0, and 27 millions of barrels as of December 31, 2025, 2024 and 2023, respectively.

Reserves Governance The company has adopted a comprehensive reserves and resources classification system modeled after a system developed and approved by a number of organizations, including the Society of Petroleum Engineers, the World Petroleum Congress and the American Association of Petroleum Geologists. The company classifies discovered recoverable hydrocarbons into six categories based on their status at the time of reporting – three deemed commercial and three potentially recoverable. Within the commercial classification are proved reserves and two categories of unproved reserves: probable and possible. The potentially recoverable categories are also referred to as contingent resources. For reserves estimates to be classified as proved, they must meet all SEC and company standards.

Proved oil and gas reserves are the estimated quantities that geoscience and engineering data demonstrate with reasonable certainty to be economically producible in the future from known reservoirs under existing economic conditions, operating methods and government regulations. Net proved reserves exclude royalties and interests owned by others and reflect contractual arrangements and royalty obligations in effect at the time of the estimate.

Proved reserves are classified as either developed or undeveloped. Proved developed reserves are the quantities expected to be recovered through existing wells with existing equipment and operating methods, or in which the cost of the required equipment is relatively minor compared to the cost of a new well. Proved undeveloped reserves are the quantities expected to be recovered from new wells on undrilled acreage or from existing wells where a relatively major expenditure is required for recompletion.

Due to the inherent uncertainties and the limited nature of reservoir data, estimates of reserves are subject to change as additional information becomes available.

Proved reserves are estimated by company asset teams composed of earth scientists and engineers. As part of the internal control process related to reserves estimation, the company maintains a Reserves Advisory Committee (RAC) that is chaired by the Manager of Reserves and Storage, an organization that is separate from the business organizations that estimate reserves. The Manager of Reserves and Storage has more than 35 years of experience working in the oil and gas industry and holds both undergraduate and graduate degrees in geoscience. His experience includes various technical and management roles in providing reserve and resource estimates in support of major capital and exploration projects, and more than 10 years of overseeing oil and gas reserves processes. He has been named a Distinguished Lecturer by the American Association of Petroleum Geologists and is an active member of the American Association of Petroleum Geologists, the SEPM Society of Sedimentary Geologists and the Society of Petroleum Engineers.

All RAC members are degreed professionals, each with more than 10 years of experience in various aspects of reserves estimation relating to reservoir engineering, petroleum engineering, earth science or finance. The members are knowledgeable in SEC guidelines for proved reserves classification and receive annual training on the preparation of reserves estimates.

The RAC has the following primary responsibilities: establish the policies and processes used within the business organizations to estimate reserves; provide independent reviews and oversight of the business units’ recommended reserves estimates and changes; confirm that proved reserves are recognized in accordance with SEC guidelines; determine that reserve quantities are calculated using consistent and appropriate standards, procedures and technology; and maintain the Chevron Corporation Reserves Manual, which provides standardized procedures used corporatewide for classifying and reporting hydrocarbon reserves.

During the year, the RAC is represented in meetings with each of the company’s business organizations and regions to review and discuss reserve changes recommended by the various asset teams. Major changes are also reviewed with the company’s senior leadership team including the Chief Executive Officer and the Chief Financial Officer. The company’s annual reserves activity is also reviewed with the company’s Board Audit Committee and Board of Directors. If major changes to reserves were to occur between the annual reviews, those matters would also be discussed with the Board.

RAC sub-teams also conduct in-depth reviews during the year of many of the fields that have large proved reserves quantities. These reviews include an examination of the proved reserve records and documentation of their compliance with the Chevron Corporation Reserves Manual.

The acquisition of Hess Corporation (Hess) was completed on July 18, 2025. Given the timing of the acquisition, Chevron has continued to rely on legacy Hess reserves staff and processes for reviewing reserves with input and guidance from the Chevron RAC. The processes include internal reviews and an external audit. Accordingly, the company continued to retain DeGolyer and MacNaughton, an independent petroleum engineering consulting firm, to complete an audit of the legacy Hess proved reserves at December 31, 2025 (representing approximately 13 percent of Chevron’s total proved reserves). Based upon their evaluation, DeGolyer and MacNaughton issued an unqualified audit opinion, and their report is attached as Exhibit 99.2 to this Annual Report on Form 10-K.

Technologies Used in Establishing Proved Reserves Additions In 2025, additions to Chevron’s proved reserves were based on a wide range of geologic and engineering technologies. Information generated from subsurface data and geoscience and engineering analysis was used in both proprietary and commercially available analytic tools, including reservoir simulation, geologic modeling and seismic processing, to provide “reasonably certain” proved reserves estimates. These technologies have been utilized extensively by the company in the past, and the company believes that they provide a high degree of confidence in establishing reliable and consistent reserves estimates.

Proved Undeveloped Reserves

Noteworthy changes in proved undeveloped reserves are shown in the table below and discussed below.

In 2025, revisions include an increase of 55 million BOE in Israel, primarily at the Leviathan field, based on production performance-driven reservoir model changes that resulted in a re-allocation of proved developed and proved undeveloped reserves estimates. In Australia, there was an increase of 40 million BOE, largely attributable to positive reservoir performance at Jansz Io. The net decrease of 34 million BOE in the United States was primarily from the Denver-Julesburg (DJ) Basin with a decrease of 49 million BOE mainly due to portfolio optimization, partially offset by positive revisions in the Midland and Delaware basins. In Argentina, a negative revision of 33 million BOE was primarily attributable to shale and tight portfolio optimization.

In 2025, extensions and discoveries in the United States totaled 214 million BOE, primarily attributable to planned development of new locations in shale and tight assets in the Midland and Delaware basins (136 million BOE) and in the DJ Basin (73 million BOE). In Australia, additions of 128 million BOE resulted from the sanctioning of the Gorgon Stage 3 project. In Other Americas, extensions and discoveries totaled 95 million BOE, primarily attributable to the Hammerhead project sanctioned in Guyana (52 million BOE) and to additions from shale and tight assets in Argentina (40 million BOE).

In 2025, purchases of 221 million BOE in the United States are primarily attributable to the acquisition of Hess assets in North Dakota. In Other Americas, purchases of 193 million BOE are attributable to the acquisition of Hess interests in the Stabroek block in Guyana.

The difference in 2025 extensions and discoveries of 167 million BOE, between the net quantities of proved reserves of 607 million BOE as reflected on pages 116 through 118 and net quantities of proved undeveloped reserves of 440 million BOE, is primarily due to proved extensions and discoveries that were not recognized as proved undeveloped reserves in the prior year and were recognized directly as proved developed reserves in 2025.

Transfers to proved developed reserves in 2025 include 544 million BOE in the United States, from the Midland and Delaware basins (279 million BOE), Gulf of America (153 million BOE), and DJ Basin (112 million BOE). Other significant transfers to proved developed were 170 million BOE in Kazakhstan, largely driven by the startup of the Future Growth Project at TCO. A combined 86 million BOE of transfers to proved developed were recorded in Argentina, the Partitioned Zone, Australia, Nigeria, Angola, Canada, and other international locations. These transfers are the consequence of development expenditures on completing wells and facilities.

During 2025, the company’s investments totaled approximately $7.1 billion in oil and gas producing activities, and about $0.1 billion in non-oil and gas producing activities, to advance the development of proved undeveloped reserves. The United States accounted for about $4.3 billion primarily related to various development activities in the Midland and Delaware basins, the Gulf of America and the DJ Basin. In Africa, about $1.0 billion was expended on various offshore development and natural gas projects in Nigeria and Angola. An additional $0.6 billion was spent on development activities in Australia. Development activities in other international locations were primarily responsible for about $1.2 billion of expenditures. The company’s equity affiliates investments in oil and gas producing activities to advance development of proved undeveloped reserves in 2025 was $0.5 billion primarily related to development projects for TCO in Kazakhstan.

Reserves that remain proved undeveloped for five or more years are a result of several factors that affect optimal project development and execution. These factors may include the complex nature of the development project in adverse and remote locations, physical limitations of infrastructure or plant capacities that dictate project timing, compression projects that are pending reservoir pressure declines, and contractual limitations that dictate production levels.

At year-end 2025, the company held approximately 396 million BOE of proved undeveloped reserves that have remained undeveloped for five years or more. The majority of these reserves are in locations where the company has a proven track record of developing major projects. In Australia, approximately 205 million BOE remain undeveloped for five years or more related to the Gorgon and Wheatstone Projects. Further field development to convert the remaining proved undeveloped reserves is scheduled to occur in line with operating constraints, reservoir depletion and infrastructure optimization. In Africa, approximately 137 million BOE have remained undeveloped for five years or more, due to facility constraints at various fields and infrastructure associated with the Escravos gas projects in Nigeria.

Annually, the company assesses whether any changes have occurred in facts or circumstances, such as changes to development plans, regulations, or government policies, that would warrant a revision to reserve estimates. In 2025, the positive impacts of higher natural gas prices in North America and of lower oil prices in production sharing contracts more than offset the negative impact of lower oil prices in tax and royalty assets, resulting in a proved reserve increase of approximately 57 million BOE. The year-end reserves quantities have been updated for these circumstances and significant changes are discussed in the appropriate reserves sections herein. Over the past three years, the ratio of proved undeveloped reserves to total proved reserves has ranged between 27 percent and 31 percent.

Proved Reserve Quantities For the three-year period ended December 31, 2025, the pattern of net reserve changes shown in the following tables is not necessarily indicative of future trends. Apart from acquisitions, the company’s ability to add proved reserves can be affected by events and circumstances that are outside the company’s control, such as delays in government permitting, partner approvals of development plans, changes in oil and gas prices, OPEC constraints, geopolitical uncertainties, civil unrest, events of war or military conflicts.

At December 31, 2025, proved reserves for the company were 10.6 billion BOE. The company’s estimated net proved reserves of liquids, including crude oil, condensate and synthetic oil for the years 2023, 2024 and 2025, are shown in the table on page 116. The company’s estimated net proved reserves of natural gas liquids (NGLs) are shown on page 117, and the company’s estimated net proved reserves of natural gas are shown on page 118.

Table VI - Standardized Measure of Discounted Future Net Cash Flows Related to Proved Oil and Gas Reserves

The standardized measure of discounted future net cash flows is calculated in accordance with SEC and FASB requirements. This includes using the unweighted arithmetic average of the first-day-of-the-month oil and gas prices for the 12-month period prior to the end of the reporting period, estimated future development and production costs assuming the continuation of existing economic conditions, estimated costs for asset retirement obligations (includes costs to retire existing wells and facilities in addition to those future wells and facilities necessary to produce proved undeveloped reserves), and estimated future income taxes based on appropriate statutory tax rates. Discounted future net cash flows are calculated using 10 percent mid-period discount factors. Estimates of proved reserve quantities are imprecise and change over time as new information becomes available. Probable and possible reserves, which may become proved in the future, are excluded from the calculations. The valuation requires assumptions as to the timing and amount of future development and production costs, which could change over time as new information becomes available. The calculations are made as of December 31 each year and do not represent management’s estimate of the company’s future cash flows or value of its oil and gas reserves. In the following table, the caption “Standardized Measure Net Cash Flows” refers to the standardized measure of discounted future net cash flows.
