You should carefully consider the following risk factors in addition to the other information included in this report. Each of these risks could adversely affect our business, financial condition, results of operations, and/or liquidity, as well as, in certain cases, the value of an investment in our securities. Although the risks are organized by headings and each risk is discussed separately, many are interrelated.

BUSINESS, INDUSTRY, AND OPERATIONS RISKS

Our financial results are affected by volatile margins, which are dependent upon factors beyond our control, including the prices we pay to acquire feedstocks and the market prices at which we can sell our products.

Our financial results are affected by the margin (i.e., the difference) between our product prices and the prices for crude oil, corn, and other feedstocks that we purchase, which can vary greatly based on global and regional market conditions, as well as by type and class of product or feedstock. Historically, product margins have been volatile, and we believe they will continue to be volatile in the future. The prices we pay to acquire feedstocks and the market prices at which we can ultimately sell our products depend upon several factors, including global and regional supplies, inventory levels, and availability of and demand for feedstocks, liquid transportation fuels, and other products. These in turn depend on, among other things, global and regional production levels, or capacities of suppliers and competitors; operational costs and flexibility (including natural gas, electricity, and water availability and costs); transportation and logistics availability and costs; proximity and access to product and feedstock supplies and markets; economic activity and growth levels; U.S. and foreign relations (including tariffs, duties, sanctions, or other trade restrictions); political affairs; government regulations; and the events described in many of the other risk factors below. The ability of the members of the Organization of Petroleum Exporting Countries (OPEC) and other petroleum-producing nations that collectively make up OPEC+ to agree on and to maintain crude oil price and production controls has also had, and is likely to continue to have, a significant impact on the market prices of crude oil and certain of our products. Although several refinery closures have recently been announced or are in process and others are expected in the future, there have also been recent additions to global refining capacity, which create risks and uncertainties related to product margins, volatility, and market perceptions of the refining industry. Regarding low-carbon fuels margins, see also, among other risk factors set forth below, “The availability and prices of our feedstocks and other critical supplies expose us to risks,” and “We are subject to risks arising from the Renewable and Low-Carbon Fuel Programs, and other regulations, policies, international certifications, and standards impacting low-carbon fuels.”

Many of these factors are interrelated, beyond our control, can vary globally and regionally, and may change quickly, adding to market volatility, while others may have longer-term effects that are uncertain. We do not produce any of our primary feedstocks (other than DCOs produced by our ethanol plants), and must purchase nearly all of the feedstocks we process. We generally purchase our feedstocks long before we process them and sell the resulting products. Price level changes during the period between purchasing feedstocks and selling the resulting products have had, and could continue to have, a significant effect on our financial results. A decline in market prices for our products and feedstocks has also had, and could again have, a negative impact to the carrying value of our inventories. Factors outside of our control, such as economic, legal, regulatory, and political uncertainties; global geopolitical and other conflicts and tensions; inflation (and the potential for increased prices to reduce demand); prolonged periods of high interest rates; and public health crises (such as pandemics or epidemics) have negatively affected, and many such factors could continue to negatively affect, economic activity and growth levels of the U.S.

and other countries. In turn, the demand for and consumption of our products, and also our revenues, margins, growth prospects, and capital allocation decisions have been and could again be negatively impacted.

A significant portion of our profitability is derived from the ability to purchase and process crude oil feedstocks that historically have been cheaper than benchmark crude oils. These crude oil feedstock differentials vary significantly depending on many factors, including global and regional economic conditions, trends and conditions within crude oil and refined petroleum products markets, and the events described above and in many of the other risk factors below. Previous declines in such differentials have had, and any future declines will likely again have, a negative impact on our results of operations.

We are subject to risks arising from the availability and prices of natural gas, electricity, and water.

Our operations depend on the reliable supply of natural gas, electricity, and water. We consume significant amounts of natural gas, electricity, and water to operate our refineries and plants, and the prices thereof can have a measurable effect on the total cost of our operations. Volatility in the prices for natural gas and electricity, in particular, is an ongoing risk to such costs. We also purchase other commodities whose prices may vary depending on the prices of natural gas, electricity, and water. The availability and prices of natural gas, electricity, and water have been, and could continue to be, affected by numerous events, such as (as applicable) government regulations or actions (including sanctions); rationing and curtailment; rate increases; weather (e.g., droughts, hurricanes, and periods of extreme heat or cold); logistics interruptions; electric grid outages; cybersecurity incidents; intermittent electricity generation (particularly from wind and solar); hostilities; terrorism; protests; human error; population and industry growth; infrastructure or supply mismanagement; and supply and demand imbalances.

For example, the real-time market structure of the largest grid operator in Texas exposes many of our refineries and operations located in Texas to “scarcity pricing” during periods of supply and demand imbalance. As electrification continues to grow, or if there are increased restrictions or costs imposed on the ability of utilities or power suppliers to utilize certain energy sources (such as through restrictions on, or other pressure not to use, fossil fuel or nuclear-generated electricity), there will likely be increased strains on and risks to the integrity, reliability, and resilience of electrical grids, and increased volatility and tightness in natural gas and electricity supplies across the world. These events could negatively affect the cost, reliability, and availability of our natural gas and electricity supplies and may cause sporadic outages disrupting our operations. Growing electrification and rapidly developing and increasing technology use (such as artificial intelligence (AI), computer processing, cryptocurrency mining, and cloud storage, as well as the data centers and power supplies required to support these activities) will also likely increase the intermittency and decrease the reliability of electricity supplies, particularly for grids highly dependent upon wind and solar power, which exacerbate the foregoing challenges, including by increasing costs. Government and private impediments and opposition to certain infrastructure projects (including pipelines) have also resulted in, and could continue to result in, the underinvestment in, or unavailability of, the infr

RISK MANAGEMENT AND STRATEGY

We take an enterprise approach to information security risk management and governance. Our information security program and framework comprise processes, policies, practices, systems, and technologies that are designed to identify, assess, prioritize, manage, and monitor risks to our information systems, including risks from cybersecurity threats and risks associated with the use of third-party service providers.

Our established recovery approach is designed to provide for the ready availability and use of our business-critical processes in the event of any downtime, disaster, or outages. We also seek to identify and mitigate the risks associated with the use of third-party service providers through the review of their security programs prior to our engagement thereof. Additionally, our control environment and internal audit process are designed to bring a systematic, disciplined approach to evaluate our risk management, control, and governance processes concerning cybersecurity and our information security framework.

We have a cybersecurity Incident Response Plan (IRP) that sets forth a process designed to effectively respond to an incident by obtaining information, coordinating activities, assessing results, and communicating applicable developments to our stakeholders, including employees, law enforcement, other external parties and agencies, and our Board. The IRP includes the following major components: preparation, detection and analysis, containment, eradication, notification, recovery, reporting, and lessons learned. Specific technical and legal playbooks have also been developed for data breaches, malware, unauthorized remote access, ransomware, and ransom-related incidents. We have also retained certain third-party experts to assist us with various aspects of incident assessment and response in the event those services become necessary or useful.

Typically, we (i) perform periodic tabletop exercises with a company-wide cross-functional team that are facilitated by a third-party expert and are intended to simulate a real-life security incident, (ii) conduct penetration testing as needed and annually conduct Payment Card Industry Data Security Standard testing and firewall reviews, and have periodically engaged a third-party expert to help therewith, (iii) hold annual cybersecurity awareness trainings, and (iv) periodically engage a third-party expert to conduct a review of our information security framework, which is designed to help identify existing and emerging risks, and mitigate such risks. These internal efforts and external third-party reviews also support our efforts to regularly assess our information security program and framework against emerging risks, market and industry developments and provide opportunities to make adjustments or enhancements when deemed prudent or necessary. In 2024, we established a company-wide cross-functional team to assess the risks and opportunities from conventional and generative AI. We continued these assessments in 2025 and expect to continue these efforts going forward. To date, there have been no cybersecurity incidents that have materially affected us, or that are reasonably likely to materially affect us, including our business strategy, financial condition, or results of operations.

For additional information on the cybersecurity risks we face, see “ITEM 1A. RISK FACTORS—CYBERSECURITY AND PRIVACY RELATED RISKS—We are subject to risks arising from a significant breach of our information systems.”

GOVERNANCE

Our Board’s Role in Cybersecurity Oversight

Oversight of risk management, including with respect to risks from cybersecurity threats, is the responsibility of our Board, which exercises its oversight responsibilities both directly and through its committees. The Audit Committee of our Board has formal oversight responsibilities established in its committee charter concerning our initiatives and strategies respecting cybersecurity and information technology risks. At least once annually, the heads of our information services and internal audit teams provide a report to the Audit Committee on cybersecurity and information technology risks, as well as our information security operations, structure, framework, various cybersecurity and information technology metrics, our cybersecurity and information security management and improvement efforts, future projects, and our governance and assessments related to cybersecurity and information technology. The chair of the Audit Committee reports to the Board a summary of the information presented by the heads of our information services and internal audit teams during their cybersecurity update. Periodically, the Board also receives reports on such matters directly. As noted above, the IRP also contains notification procedures to the Board.

Management’s Role in Assessment and Management of Material Risks from Cybersecurity Threats

We have an Information Security Committee (Infosec Committee) consisting of refining, renewables, logistics, human resources, and information services personnel that typically meets weekly to evaluate third-party exchange of data and collaborate on strategy for dealing with information security risks and other related matters. The Infosec Committee reports to our Information Security Oversight Committee (Infosec Oversight Committee) and our Executive Steering Committee on cybersecurity (Executive Steering Committee). Our Infosec Oversight Committee consists of information services, refining, and internal audit personnel and typically meets quarterly to discuss network threats and the overall security landscape. Our Executive Steering Committee consists of management within our information services, internal audit, refining, renewable diesel, ethanol, legal, and logistics teams, and typically meets twice per year to review and discuss information security metrics and results of security assessments, among other items. Key members of the Infosec Oversight Committee and the Executive Steering Committee provide a report to the Audit Committee of the Board as discussed above.

Our information services team is led by our Vice President-Information Services and Technology, who also chairs the Infosec Oversight Committee and has approximately 25 years of experience in the information technology industry. Collectively, the members of our Infosec Committee, Infosec Oversight Committee, and Executive Steering Committee have decades of experience within the information technology industry and/or cybersecurity areas. On a monthly basis, our Vice President-Information Services and Technology provides executive management with an Information Security Scorecard, which includes any cybersecurity incidents that have occurred. If a cybersecurity incident is declared under the IRP, we will evaluate whether such incident might have a material adverse impact on our business, financial condition, results of operations, or reputation, among other considerations, and communicate that discussion to executive management, who will then determine if escalation to the Board is warranted and if further disclosure is required to the SEC, other government agencies, and/or other parties.

LITIGATION

We incorporate by reference into this item our disclosures made in Note 1 of Notes to Consolidated Financial Statements under “Legal Contingencies.”

ENVIRONMENTAL ENFORCEMENT MATTERS

SEC regulations require us to disclose certain information about proceedings arising under federal, state, or local provisions regulating the discharge of materials into the environment or primarily for the purpose of protecting the environment if a governmental authority is a party to such proceeding and we reasonably believe that such proceeding will result in monetary sanctions that exceed a specified threshold. There were no proceedings required to be disclosed in this item under SEC regulations. Pursuant to SEC regulations, we use a threshold of $1 million for purposes of determining whether disclosure of any such proceedings is required. We believe any such proceedings less than this threshold are not material to our business and financial condition.

None.

PART II

Our common stock trades on the NYSE under the trading symbol “VLO.”

As of January 31, 2026, there were 3,996 holders of record of our common stock.

Dividends are considered quarterly by the Board, may be paid only when approved by the Board, and will depend on our financial condition, results of operations, cash flows, prospects, industry conditions, capital requirements, and other factors and restrictions our Board deems relevant. There can be no assurance that we will pay a dividend in the future at the rates we have paid historically, or at all.

The following table discloses purchases of shares of our common stock made by us or on our behalf during the fourth quarter of 2025.

(a)The shares reported in this column include 102,682 shares related to our purchases of shares from participants in our stock-based compensation plans in connection with the vesting of restricted stock and other stock compensation transactions in accordance with the terms of our stock-based compensation plans.

(b)The average price paid per share reported in this column excludes brokerage commissions and a one percent excise tax on share purchases.

(c)On February 22, 2024, we announced that our Board authorized us to purchase shares of our outstanding common stock for a total cost of up to $2.5 billion with no expiration date, and we completed all authorized share purchases under that program during the fourth quarter of 2025. On October 29, 2024, we announced that our Board authorized us to purchase shares of our outstanding common stock for a total cost of up to $2.5 billion with no expiration date (the September 2024 Program). This authorization was granted on September 19, 2024. As of December 31, 2025, we had $1.7 billion remaining available for purchase under the September 2024 Program. On February 25, 2026, our Board authorized us to purchase shares of our outstanding common stock for a total cost of up to $2.5 billion with no expiration date, which is in addition to the amount remaining under the September 2024 Program.

The performance graph below is not “soliciting material,” is not deemed filed with the SEC, and is not to be incorporated by reference into any of our filings under the Securities Act of 1933 or the Securities Exchange Act of 1934, respectively.

This performance graph and the related textual information are based on historical data and are not indicative of future performance. The following line graph compares the cumulative total return4 on an investment in our common stock against the cumulative total return of the S&P 500 Composite Index and an index of peers (that we selected) for the five-year period commencing December 31, 2020 and ending December 31, 2025. Our selected peer group comprises the following eleven members: ConocoPhillips; CVR Energy, Inc.; Delek US Holdings, Inc.; the Energy Select Sector SPDR Fund; EOG Resources, Inc.; HF Sinclair Corporation; LyondellBasell Industries N.V.; Marathon Petroleum Corporation; Occidental Petroleum Corporation; PBF Energy Inc.; and Phillips 66. The Energy Select Sector SPDR Fund (XLE) serves as a proxy for stock price performance of the energy sector and includes energy companies with which we compete for capital. We believe that our peer group represents a group of companies for making head-to-head performance comparisons in a competitive operating environment that is primarily characterized by U.S.-based companies that have business models predominantly consisting of downstream refining operations, together with similarly sized energy companies that share operating similarities to us, and that are in adjacent segments of the oil and gas industry.

COMMODITY PRICE RISK

We are exposed to market risks related to the volatility in the price of feedstocks (primarily crude oil, waste and renewable feedstocks, and corn), the products we produce, and natural gas used in our operations. To reduce the impact of price volatility on our results of operations and cash flows, we use commodity derivative instruments, including futures and options to manage the volatility of:

• inventories and firm commitments to purchase inventories generally for amounts by which our current year inventory levels (determined on a LIFO basis) differ from our previous year-end LIFO inventory levels; and

• forecasted purchases and/or product sales at existing market prices that we deem favorable.

Our positions in commodity derivative instruments are monitored and managed on a daily basis by our risk control group to ensure compliance with our stated risk management policy that is periodically reviewed with our Board and/or relevant Board committee.

As of December 31, 2025 and 2024, the amount of gain or loss that would have resulted from a 10 percent increase or decrease in the underlying price for all of our commodity derivative instruments entered into for purposes other than trading with which we have market risk was not material. See Note 20 of Notes to Consolidated Financial Statements for notional volumes associated with these derivative contracts as of December 31, 2025.

COMPLIANCE PROGRAM PRICE RISK

We are exposed to market risk related to the volatility in the price of credits needed to comply with the Renewable and Low-Carbon Fuel Programs. To manage this risk, we enter into contracts to purchase these credits. As of December 31, 2025 and 2024, the amount of gain or loss in the fair value of derivative instruments that would have resulted from a 10 percent increase or decrease in the underlying price of the contracts was not material. See Note 20 of Notes to Consolidated Financial Statements for a discussion about these blending programs.

INTEREST RATE RISK

The following tables provide information about our debt instruments (dollars in millions), the fair values of which are sensitive to changes in interest rates. A 10 percent increase or decrease in our floating interest rates would not have a material effect on our results of operations. Principal cash flows and related weighted-average interest rates by expected maturity dates are presented. See Note 9 of Notes to Consolidated Financial Statements for additional information related to our debt.

(a)Excludes unamortized discounts and debt issuance costs.

FOREIGN CURRENCY RISK

We are exposed to exchange rate fluctuations on transactions related to our foreign operations that are denominated in currencies other than the local (functional) currencies of those operations. To manage our exposure to these exchange rate fluctuations, we often use foreign currency contracts.

MANAGEMENT’S REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING

Our management is responsible for establishing and maintaining adequate “internal control over financial reporting” (as defined in Rule 13a-15(f) under the Securities Exchange Act of 1934) for Valero Energy Corporation. Our management evaluated the effectiveness of Valero’s internal control over financial reporting as of December 31, 2025. In its evaluation, management used the criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Management believes that as of December 31, 2025, our internal control over financial reporting was effective based on those criteria.

Our independent registered public accounting firm has issued an attestation report on the effectiveness of our internal control over financial reporting, which begins on page 72 of this report.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Stockholders

Valero Energy Corporation:

Opinion on the Consolidated Financial Statements

We have audited the accompanying consolidated balance sheets of Valero Energy Corporation and subsidiaries (the Company) as of December 31, 2025 and 2024, the related consolidated statements of income, comprehensive income, equity, and cash flows for each of the years in the three-year period ended December 31, 2025, and the related notes (collectively, the consolidated financial statements). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2025 and 2024, and the results of its operations and its cash flows for each of the years in the three-year period ended December 31, 2025, in conformity with U.S. generally accepted accounting principles.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company’s internal control over financial reporting as of December 31, 2025, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission, and our report dated February 25, 2026 expressed an unqualified opinion on the effectiveness of the Company’s internal control over financial reporting.

Basis for Opinion

These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these consolidated financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. We believe that our audits provide a reasonable basis for our opinion.

Critical Audit Matters

The critical audit matters communicated below are matters arising from the current period audit of the consolidated financial statements that were communicated or required to be communicated to the audit committee and that: (1) relate to accounts or disclosures that are material to the consolidated financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the consolidated

financial statements, taken as a whole, and we are not, by communicating the critical audit matters below, providing separate opinions on the critical audit matters or on the accounts or disclosures to which they relate.

Sufficiency of audit evidence over quantities of inventories

As discussed in Note 4 to the consolidated financial statements, the Company held $7.6 billion of inventories as of December 31, 2025. The Company’s inventories are held across its refineries, renewable diesel plants, ethanol plants, and third-party locations.

We identified the evaluation of the sufficiency of audit evidence obtained related to the quantities of inventories at the multi-locations as a critical audit matter. Evaluating the sufficiency of audit evidence over quantities of inventories at the multi-locations required challenging auditor judgment to determine the nature and extent of procedures to be performed. This included determining the number of locations and which locations to visit.

The following are the primary procedures we performed to address this critical audit matter. We applied auditor judgment to determine the nature and extent of procedures to be performed over quantities of inventories at the multi-locations by evaluating:

• homogeneity of the locations

• historical locations visited and results of prior physical counts

• inventory dollars by location.

We evaluated the design and tested the operating effectiveness of certain internal controls related to the quantities of inventories held at multi-locations. This included certain controls related to the Company's inventory count process and reconciliations of inventories at the multi-locations. We assessed the recorded quantities of inventories by counting inventory quantities on a selection basis through location visits during the year and comparing counted quantities to the Company’s inventory records. We also obtained external confirmation of inventory quantities held at certain third-party locations. We evaluated the overall sufficiency of audit evidence obtained over the quantities of inventories at multi-locations by assessing the results of procedures performed including the appropriateness of the nature and extent of audit evidence.

Fair value of certain long-lived assets

As discussed in Note 1 to the consolidated financial statements, long-lived assets are tested for recoverability whenever events or changes in circumstances indicate that the carrying amount of the asset may not be recoverable. A long-lived asset is not deemed recoverable if its carrying amount exceeds the sum of the undiscounted cash flows expected to result from its use and eventual disposition. If a long-lived asset is not deemed recoverable, an impairment loss is recognized for the amount by which the carrying amount of the long-lived asset exceeds its fair value. As discussed in Note 2, as of March 31, 2025, the Company updated their evaluation of potential impairment and concluded that the carrying values of the Benicia and Wilmington refineries were not recoverable. As a result, the Company reduced the carrying values of these assets to their estimated fair values and recognized a combined asset impairment loss of $1.1 billion. As discussed in Note 19, the fair values of the refineries were determined using a market approach based on a comparison of recent property sales and other relevant real estate and market data.

We identified the evaluation of fair value of the Benicia and Wilmington refineries as a critical audit matter. Subjective and challenging auditor judgment was required to assess certai
