NON-GAAP FINANCIAL MEASURES

The following discussions in “OVERVIEW AND OUTLOOK,” “RESULTS OF OPERATIONS,” and “LIQUIDITY AND CAPITAL RESOURCES” include references to financial measures that are not defined under U.S. generally accepted accounting principles (GAAP). These non-GAAP financial measures include Refining, Renewable Diesel, and Ethanol segment margin; adjusted operating income (including adjusted operating income for each of our reportable segments, as applicable); Refining segment adjusted operating expenses (excluding depreciation and amortization expense); and capital investments attributable to Valero. We have included these non-GAAP financial measures to help facilitate the comparison of operating results between years, to help assess our cash flows, and because we believe they provide useful information as discussed further below. Refer to the tables in note (f), beginning on page 53, for the reconciliations of Refining, Renewable Diesel, and Ethanol segment margin; adjusted operating income (including adjusted operating income for each of our reportable segments, as applicable); and adjusted Refining operating expenses (excluding depreciation and amortization expense) to their most directly comparable GAAP financial measures. Also in note (f), we disclose the reasons why we believe our use of such non-GAAP financial measures provides useful information. See the table on page 61 for a reconciliation of capital investments attributable to Valero to its most directly comparable GAAP financial measure, and also on page 61, we disclose the reasons why we believe our use of this non-GAAP financial measure provides useful information.

OVERVIEW AND OUTLOOK

Overview

Business Operations Update

Our results for the year ended December 31, 2025 were supported by strong worldwide demand for petroleum-based transportation fuels, while worldwide supply of those products remained constrained. However, our results were also impacted by the asset impairment loss of $1.1 billion ($877 million after taxes) associated with our operations in California, as described in Note 2 of Notes to Consolidated Financial Statements.

Our results, particularly for our Renewable Diesel segment, were also negatively impacted by trade and other policy changes during 2025. For instance, the U.S. federal government implemented new or revised tariffs, duties, and other actions with respect to U.S. and foreign trade, manufacturing, and investment that impacted our business operations during 2025. Although energy commodities, including crude oil and refined petroleum products, are generally exempt from the recently effective U.S. tariffs, our Renewable Diesel segment was subject to new tariffs on renewable feedstocks imported into the U.S. These tariffs have at times made the use of certain feedstocks, particularly foreign-sourced feedstocks, economically impractical and resulted in reduced margins. We have taken actions to mitigate the impact of tariffs and duties on our business, including utilizing established free-trade zones, adjusting our feedstock slates, and optimizing our supply chain. Also, a significant portion of the new tariffs and existing duties we incurred are eligible for recovery through duty drawback claims, and we have implemented processes that allow us to file such claims in an efficient and timely manner.

In addition, effective January 1, 2025, the blender’s tax credit, which offered a tax incentive of $1.00 per gallon to blenders of certain renewable fuels, was replaced by the clean fuel production credit. The clean fuel production credit is a tax credit available for qualifying sales of certain low-carbon transportation fuels produced in the U.S. and the value of the credit is dependent on the CI of the fuel, among other factors. The transition to the clean fuel production credit has resulted in fewer volumes being eligible for a tax credit as well as lower credit values for fuels that were previously incentivized under the blender’s tax credit, which had a negative impact on our Renewable Diesel segment margins.

For a discussion on the risks and uncertainties with respect to trade and other policy matters discussed above, see “ITEM 1A. RISK FACTORS—BUSINESS, INDUSTRY, AND OPERATIONS RISKS—The availability and prices of our feedstocks and other critical supplies expose us to risks.”

For the year ended December 31, 2025, we reported $2.3 billion of net income attributable to Valero stockholders driven by strong demand for our products and continued strength in refining margins. Our operating results for 2025, including operating results by segment, are described in the summary on the following page, and detailed descriptions can be found under “RESULTS OF OPERATIONS” beginning on page 46.

Our operations generated $5.8 billion of cash in 2025. Also, we issued $650 million of 5.150 percent Senior Notes due February 15, 2030 during 2025, as described in Note 9 of Notes to Consolidated Financial Statements. The cash generated by our operations, along with the net proceeds from our debt issuance, was used to make $1.9 billion of capital investments in our business, return $4.0 billion to our stockholders through purchases of common stock for treasury and dividend payments, and repay $440 million of our public debt that matured in 2025. As a result of this and other activity during the year, our cash, cash equivalents, and restricted cash increased by $36 million to $4.9 billion as of December 31, 2025. We had $9.8 billion in liquidity as of December 31, 2025. The components of our liquidity and

descriptions of our cash flows, capital investments, and other matters impacting our liquidity and capital resources can be found under “LIQUIDITY AND CAPITAL RESOURCES” beginning on page 57.

Results for the Year Ended December 31, 2025

For 2025, we reported net income attributable to Valero stockholders of $2.3 billion compared to $2.8 billion for 2024. The decrease of $422 million was primarily due to decreases in operating income of $574 million and “other income, net” of $119 million, partially offset by a decrease in net income attributable to noncontrolling interests of $338 million. The details of our operating income (loss) and adjusted operating income, where applicable, by segment and in total are reflected below (in millions). Adjusted operating income excludes the adjustments reflected in the tables in note (f) beginning on page 53.

While our operating income decreased by $574 million in 2025 compared to 2024, adjusted operating income increased by $615 million primarily due to the following:

•Refining segment. Refining segment adjusted operating income increased by $1.3 billion primarily due to higher gasoline, distillate (primarily diesel), and other product margins and an increase in throughput volumes, partially offset by a decline in crude oil and other feedstock differentials and increases in adjusted operating expenses (excluding depreciation and amortization expense) and depreciation and amortization expense.

•Renewable Diesel segment. Renewable Diesel segment operating income decreased by $663 million primarily due to higher feedstock costs and a decline in the value of low-carbon fuel tax incentives, partially offset by higher product prices (primarily renewable diesel) and a decrease in operating expenses (excluding depreciation and amortization expense).

•Ethanol segment. Ethanol segment adjusted operating income increased by $59 million primarily due to higher ethanol prices and an increase in production volumes, partially offset by higher corn prices and an increase in operating expenses (excluding depreciation and amortization expense).

Outlook

Many uncertainties remain with respect to the supply and demand balances in petroleum-based product markets worldwide. While it is difficult to predict future worldwide economic activity and its resulting impact on product supply and demand, including the effects of tariffs thereon, we have noted several factors below that have impacted or may impact our results of operations during the first quarter of 2026.

•Global demand for gasoline, diesel, and jet fuel continues to rise, with growth in demand for jet fuel outpacing growth of other primary petroleum-based transportation fuels. In addition, colder temperatures across the North Atlantic and moderation in biofuel consumption growth are expected to support petroleum-based diesel demand.

•Expected reductions in refining capacity in the U.S. and Europe, unplanned outages at Russian refineries due to the Russia-Ukraine conflict, and a prolonged ramp-up of new capacity in emerging markets continue to support utilization of remaining global refining capacity.

•Crude oil differentials are expected to widen as a result of an increase in sour crude oil production from OPEC+ suppliers and recent developments involving the Venezuelan government and associated sanctions. However, potential sanction adjustments related to Iran and Russia, ongoing uncertainty in Venezuela, and the continued Russia-Ukraine conflict could result in increased volatility in the crude oil market and potentially impact crude oil differentials.

•Renewable diesel demand is expected to remain consistent with current levels.

•Ethanol demand is expected to follow typical seasonal patterns.

Total Company, Corporate, and Other

The following table includes selected financial data for the total company, corporate, and other for 2025 and 2024. The selected financial data is derived from the Financial Highlights by Segment and Total Company tables, unless otherwise noted.

Revenues decreased by $7.2 billion in 2025 compared to 2024 primarily due to decreases in product prices for the petroleum-based transportation fuels associated with sales made by our Refining segment. This decrease in revenues, along with the effect of an asset impairment loss of $1.1 billion in 2025 (see note (d)), was partially offset by a decrease in cost of sales of $7.8 billion primarily due to decreases in crude oil and other feedstock costs.

Operating income decreased by $574 million in 2025; however, adjusted operating income, which excludes the adjustments in the table in note (f), increased by $615 million, from $3.8 billion in 2024 to $4.4 billion in 2025. The components of this $615 million increase in adjusted operating income are discussed by segment in the segment analyses that follow.

“Other income, net” decreased by $119 million in 2025 compared to 2024 primarily due to lower interest income on cash driven by a decrease in interest rates in 2025.

49

Table of Contents

Net income attributable to noncontrolling interests decreased by $338 million in 2025 compared to 2024 primarily due to lower earnings associated with DGD, whose operations compose our Renewable Diesel segment. See Note 12 of Notes to Consolidated Financial Statements regarding our accounting for DGD and the Renewable Diesel segment analysis beginning on page 51.

Refining Segment Results

The following table includes selected financial and operating data of our Refining segment for 2025 and 2024. The selected financial data is derived from the Financial Highlights by Segment and Total Company tables, unless otherwise noted.

Refining segment operating income increased by $69 million in 2025 compared to 2024; however, Refining segment adjusted operating income, which excludes the adjustments in the table in note (f), increased by $1.3 billion in 2025 compared to 2024. The components of this increase in the adjusted results, along with the reasons for the changes in those components, are outlined below.

•Refining segment margin increased by $2.1 billion in 2025 compared to 2024.

Refining segment margin is primarily affected by the prices for the petroleum-based transportation fuels that we sell and the cost of crude oil and other feedstocks that we process. The table on page 48 reflects market reference prices and differentials that we believe impacted our Refining segment margin in 2025 compared to 2024.

The increase in Refining segment margin was primarily due to the following:

◦An increase in distillate (primarily diesel) margins had a favorable impact of approximately $1.8 billion.

◦An increase in margins for products other than gasoline and distillates had a favorable impact of approximately $940 million.

◦An increase in gasoline margins had a favorable impact of approximately $650 million.

50

Table of Contents

◦An increase in throughput volumes of 76,000 barrels per day had a favorable impact of approximately $340 million.

◦A decline in crude oil differentials had an unfavorable impact of approximately $1.1 billion.

◦A decline in differentials for other feedstocks had an unfavorable impact of approximately $600 million.

•Refining segment adjusted operating expenses (excluding depreciation and amortization expense), which excludes the adjustment in the table in note (f), increased by $430 million primarily due to increases in energy costs of $197 million, certain employee compensation expenses of $84 million, and maintenance expenses of $69 million.

•Refining segment depreciation and amortization expense increased by $363 million primarily due to incremental depreciation expense of approximately $300 million related to our plan to idle the processing units and cease refining operations at our Benicia Refinery by the end of April 2026, as described in Note 2 of Notes to Consolidated Financial Statements.

Renewable Diesel Segment Results

The following table includes selected financial and operating data of our Renewable Diesel segment for 2025 and 2024. The selected financial data is derived from the Financial Highlights by Segment and Total Company tables, unless otherwise noted.

Renewable Diesel segment operating income decreased by $663 million in 2025 compared to 2024. The components of this decrease, along with the reasons for the changes in those components, are outlined below.

•Renewable Diesel segment margin decreased by $703 million in 2025 compared to 2024.

Renewable Diesel segment margin is primarily affected by the price for the low-carbon fuels that we sell, the value of the related low-carbon fuel tax credits, and the cost of the feedstocks that we process. The table on page 49 reflects market reference prices that we believe impacted our Renewable Diesel segment margin in 2025 compared to 2024.

51

Table of Contents

The decrease in Renewable Diesel segment margin was primarily due to the following:

◦An increase in the cost of the feedstocks processed during the period had an unfavorable impact of approximately $940 million. During 2025, we became subject to newly imposed tariffs on certain foreign-sourced renewable feedstocks, resulting in higher costs for those feedstocks. Furthermore, these tariffs resulted in increased demand for qualifying domestic feedstocks and, consequently, higher market prices for domestic-sourced feedstocks. See “OVERVIEW AND OUTLOOK—Overview—Business Operations Update” beginning on page 43 for additional discussion.

◦A decline in the value of tax incentives for low-carbon fuels had an unfavorable impact of approximately $675 million. Effective January 1, 2025, the blender’s tax credit was replaced by the clean fuel production credit. This transition resulted in a reduction in the volumes of fuel eligible for a tax credit, as well as lower credit values for certain fuels that were previously incentivized under the blender’s tax credit regime. See “OVERVIEW AND OUTLOOK—Overview—Business Operations Update” beginning on page 43 for additional discussion.

◦An increase in product prices, primarily renewable diesel, had a favorable impact of approximately $880 million.

•Renewable Diesel segment operating expenses (excluding depreciation and amortization expense) decreased by $42 million primarily due to decreases in outside services of $22 million and chemicals and catalysts costs of $19 million.

Ethanol Segment Results

The following table includes selected financial and operating data of our Ethanol segment for 2025 and 2024. The selected financial data is derived from the Financial Highlights by Segment and Total Company tables, unless otherwise noted.

Ethanol segment operating income increased by $86 million in 2025 compared to 2024; however, Ethanol segment adjusted operating income, which excludes the adjustment in the table in note (f), increased by $59 million in 2025 compared to 2024. The components of this increase in the adjusted results, along with the reasons for the changes in those components, are outlined below.

•Ethanol segment margin increased by $136 million in 2025 compared to 2024.

52

Table of Contents

Ethanol segment margin is primarily affected by prices for the ethanol and corn-related co-products that we sell and the cost of corn that we process. The table on page 49 reflects market reference prices that we believe impacted our Ethanol segment margin in 2025 compared to 2024.

The increase in Ethanol segment margin was primarily due to the following:

◦An increase in ethanol prices had a favorable impact of approximately $150 million.

◦An increase in production volumes of 73,000 gallons per day had a favorable impact of approximately $30 million.

◦An increase in corn prices had an unfavorable impact of approximately $50 million.

•Ethanol segment operating expenses (excluding depreciation and amortization expense) increased by $75 million primarily due to increases in energy costs of $55 million and certain employee compensation expenses of $12 million.

________________________

The following notes relate to references on pages 46 through 52.

(a)Cost of materials and other for the year ended December 31, 2025 includes a charge of $37 million related to the liquidation of certain LIFO inventory layers attributable to our Refining segment. Inventory levels for our West Coast refining operations decreased during the year ended December 31, 2025 in connection with our plan to idle the processing units and cease refining operations at the Benicia Refinery by the end of April 2026.

(b)Taxes other than income taxes includes excise taxes on sales by certain of our foreign operations.

(c)Operating expenses (excluding depreciation and amortization expense) for the year ended December 31, 2025 includes employee retention and separation costs of $50 million related to the Benicia Refinery. In connection with our plan to idle the processing units and cease refining operations at the Benicia Refinery, we implemented a transition plan for eligible employees, which includes retention incentive payments and separation benefits.

(d)In March 2025, we approved a plan with respect to the operations at our Benicia Refinery and currently intend to idle the processing units and cease refining operations by the end of April 2026. In addition, we considered strategic alternatives for our remaining operations in California. As a result, we evaluated the assets of the Benicia and Wilmington refineries for impairment as of March 31, 2025 and concluded that the carrying values of these assets were not recoverable. Therefore, we reduced the carrying values of the Benicia and Wilmington refineries to their estimated fair values and recognized a combined asset impairment loss of $1.1 billion in the year ended December 31, 2025.

(e)In December 2024, the Internal Revenue Service (IRS) approved our application for registration as a producer of second-generation biofuels with respect to the cellulosic ethanol produced at our ethanol plants. As a result, we recognized a current income tax benefit of $79 million in December 2024 for the tax credit attributable to volumes of cellulosic ethanol produced and sold by us in the U.S. from 2020 through 2024.

(f)We use certain financial measures (as noted below) that are not defined under GAAP and are considered to be non-GAAP measures.

We have defined these non-GAAP measures and believe they are useful to the external users of our financial statements, including industry analysts, investors, lenders, and rating agencies. We believe these measures are useful to assess our ongoing financial performance because, when reconciled to their most comparable GAAP measures, they provide improved comparability between periods after adjusting for certain items that we believe are not indicative of our core operating performance and that may obscure our underlying business results and

trends. These non-GAAP measures should not be considered as alternatives to their most comparable GAAP measures nor should they be considered in isolation or as a substitute for an analysis of our results of operations as reported under GAAP. In addition, these non-GAAP measures may not be comparable to similarly titled measures used by other companies because we may define them differently, which diminishes their utility.

Non-GAAP financial measures are as follows (in millions):

•Refining margin is defined as Refining segment operating income excluding the LIFO liquidation adjustment, operating expenses (excluding depreciation and amortization expense), depreciation and amortization expense, the asset impairment loss, and other operating expenses, as reflected in the table below.

•Renewable Diesel margin is defined as Renewable Diesel segment operating income (loss) excluding operating expenses (excluding depreciation and amortization expense) and depreciation and amortization expense, as reflected in the table below.

54

Table of Contents

•Ethanol margin is defined as Ethanol segment operating income excluding operating expenses (excluding depreciation and amortization expense), depreciation and amortization expense, and other operating expenses, as reflected in the table below.

•Adjusted Refining operating income is defined as Refining segment operating income excluding the LIFO liquidation adjustment, employee retention and separation costs, the asset impairment loss, and other operating expenses, as reflected in the table below.

•Adjusted Ethanol operating income is defined as Ethanol segment operating income excluding other operating expenses, as reflected in the table below.

55

Table of Contents

•Adjusted operating income is defined as total company operating income excluding the LIFO liquidation adjustment, employee retention and separation costs, the asset impairment loss, and other operating expenses, as reflected in the table below.

•Adjusted Refining operating expenses (excluding depreciation and amortization expense) is defined as Refining segment operating expenses (excluding depreciation and amortization expense) excluding employee retention and separation costs, as reflected in the table below.

(g)The RVO cost represents the average market cost on a per barrel basis to comply with the RFS program. The RVO cost is calculated by multiplying (i) the average market price during the applicable period for the RINs associated with each class of renewable fuel (i.e., biomass-based diesel, cellulosic biofuel, advanced biofuel, and total renewable fuel) by (ii) the quotas for the volume of each class of renewable fuel that must be blended into petroleum-based transportation fuels consumed in the U.S., as set or proposed by the EPA, on a percentage basis for each class of renewable fuel and adding together the results of each calculation.

(h)We use throughput volumes, sales volumes, and production volumes for the Refining segment, Renewable Diesel segment, and Ethanol segment, respectively, due to their general use by others who operate facilities similar to those included in our segments.

LIQUIDITY AND CAPITAL RESOURCES

Our Liquidity

Our liquidity consisted of the following as of December 31, 2025 (in millions):

_______________________

(a)Excludes the committed facilities of the consolidated VIEs.

(b)Excludes $228 million of cash and cash equivalents related to the consolidated VIEs that is for their use only.

Information about our outstanding borrowings, letters of credit issued, and availability under our credit facilities is reflected in Note 9 of Notes to Consolidated Financial Statements.

Our debt and financing agreements do not have rating agency triggers that would automatically require us to post additional collateral. However, in the event of certain downgrades of our senior unsecured debt by the ratings agencies, the cost of borrowings under some of our bank credit facilities and other arrangements may increase. As of December 31, 2025, all of our ratings on our senior unsecured debt, including debt guaranteed by us, were at or above investment grade level as follows:

We cannot provide assurance that these ratings will remain in effect for any given period of time or that one or more of these ratings will not be lowered or withdrawn entirely by a rating agency. We note that these credit ratings are not recommendations to buy, sell, or hold our securities. Each rating should be evaluated independently of any other rating. Any future reduction below investment grade or withdrawal of one or more of our credit ratings could have a material adverse impact on our ability to obtain short- and long-term financing and the cost of such financings.

We believe we have sufficient funds from operations and from available capacity under our credit facilities to fund our ongoing operating requirements and other commitments over the next 12 months and thereafter for the foreseeable future. We expect that, to the extent necessary, we can raise additional cash through equity or debt financings in the public and private capital markets or the arrangement of additional credit facilities. However, there can be no assurances regarding the availability of any future financings or additional credit facilities or whether such financings or additional credit facilities can be made available on terms that are acceptable to us.

Cash Flows

Components of our cash flows are set forth below (in millions):

Cash Flows for the Year Ended December 31, 2025

In 2025, we used the $5.8 billion of cash generated by our operations and the $7.6 billion from our debt issuance and borrowings to make $1.8 billion of investments in our business, repay $7.7 billion of debt and finance lease obligations, return $4.0 billion to our stockholders through purchases of our common stock for treasury and dividend payments, and increase our available cash on hand by $36 million. The debt issuance, borrowings, and repayments are described in Note 9 of Notes to Consolidated Financial Statements.

As previously noted, our operations generated $5.8 billion of cash in 2025, resulting from net income of $2.2 billion and noncash charges of $3.8 billion, partially offset by a negative change in working capital of $192 million. Noncash charges primarily included a $1.1 billion asset impairment loss associated with our operations in California, as described in Note 2 of Notes to Consolidated Financial Statements, and $3.2 billion of depreciation and amortization expense, partially offset by a $197 million deferred income tax benefit. Details regarding the components of the change in working capital, along with the reasons for the changes in those components, are described in Note 18 of Notes to Consolidated Financial Statements. In addition, see “RESULTS OF OPERATIONS” for an analysis of the significant components of our net income.

Our investing activities of $1.8 billion primarily consisted of $1.9 billion in capital investments, as defined on the following page under “Capital Investments,” of which $170 million related to capital investments made by DGD.

Cash Flows for the Year Ended December 31, 2024

In 2024, we used the $6.7 billion of cash generated by our operations, $7.1 billion in debt borrowings, and $595 million of cash on hand to make $2.0 billion of investments in our business, repay $7.8 billion of debt and finance lease obligations, and return $4.3 billion to our stockholders through purchases of our common stock for treasury and dividend payments. The debt borrowings and repayments are described in Note 9 of Notes to Consolidated Financial Statements.

58

Table of Contents

As previously noted, our operations generated $6.7 billion of cash in 2024, driven by net income of $3.0 billion, noncash charges of $2.9 billion, and a positive change in working capital of $795 million. Noncash charges primarily included $2.8 billion of depreciation and amortization expense. Details regarding the components of the change in working capital, along with the reasons for the changes in those components, are described in Note 18 of Notes to Consolidated Financial Statements. In addition, see “RESULTS OF OPERATIONS” for an analysis of the significant components of our net income.

Our investing activities of $2.0 billion primarily consisted of $2.1 billion in capital investments, of which $321 million related to capital investments made by DGD.

Our Capital Resources

Our material cash requirements as of December 31, 2025 primarily consisted of working capital requirements, capital investments, contractual obligations, and other matters, as described below. Our operations have historically generated positive cash flows to fulfill our working capital requirements and other uses of cash as discussed below.

Capital Investments

Capital investments consist of our capital expenditures, deferred turnaround and catalyst cost expenditures, and investments in nonconsolidated joint ventures, as reflected in our statements of cash flows as shown on page 78. Capital investments exclude acquisitions, if any.

We also identify our capital investments by the nature of the project with which the expenditure is associated as follows:

•Sustaining capital investments are generally associated with projects that are expected to extend the lives of our property assets, sustain their operating capabilities and safety (including deferred turnaround and catalyst cost expenditures), or comply with regulatory requirements. Regulatory compliance capital investments are generally associated with projects that are incurred to comply with government regulatory requirements, such as requirements to reduce emissions and prohibited elements from our products.

•Growth capital investments, including low-carbon growth capital investments that support the development and growth of our low-carbon fuels businesses, are generally associated with projects for the construction of new property assets that are expected to enhance our profitability and cash-generating capabilities, including investments in nonconsolidated joint ventures.

We have developed an extensive multi-year capital investment program, which we update and revise based on changing internal and external factors. Our capital investment program aims to manage our capital investments on average over a multi-year period given the year-to-year variability with respect to timing, costs, and other aspects of capital projects, particularly growth capital projects. Capital projects may be accelerated, deferred, or canceled based on costs, market and economic conditions, regulatory approvals, project execution, competing uses of capital, and other variables, and capital investments and costs may particularly increase or decrease at the beginning and ending of a project. The variability in our year-to-year growth capital investments primarily reflects shifts in expected timing and costs of capital projects rather than a change in our capital allocation strategy. See also “ITEM 1A. RISK FACTORS—BUSINESS, INDUSTRY, AND OPERATIONS RISKS—Our pursuit of capital and other strategic projects and actions exposes us to various risks” regarding other considerations with respect to our capital investments.

59

Table of Contents

The following table reflects our expected capital investments for the year ending December 31, 2026 by nature of the project and segment, along with historical amounts for the years ended December 31, 2025 and 2024 (in millions). The following table also reflects capital investments attributable to Valero, which is a non-GAAP measure that we define and reconcile to capital investments below under “Capital Investments Attributable to Valero.”

________________________

(a)All expected amounts for the year ending December 31, 2026 exclude capital expenditures that the consolidated VIEs (other than DGD) may incur because we do not operate those VIEs.

(b)Capital investments attributable to Valero by nature of the project are as follows (in millions):

We have a publicly disclosed GHG emissions reductions/displacements target and our capital investments in future years are expected to include investments associated with certain low-carbon projects currently at various stages of progress, evaluation, or approval in line therewith. Certain low-carbon projects and the associated capital investments are also included in our expected capital investments for 2026.

Table of Contents

Capital Investments Attributable to Valero

Capital investments attributable to Valero is a non-GAAP financial measure that reflects our net share of capital investments and is defined as all capital expenditures, deferred turnaround and catalyst cost expenditures, and investments in nonconsolidated joint ventures, excluding the portion of DGD’s capital investments attributable to the other joint venture member and all of the capital expenditures of other consolidated VIEs.

We are a 50 percent joint venture member in DGD and consolidate its financial statements, and DGD’s operations compose our Renewable Diesel segment. As a result, all of DGD’s net cash provided by operating activities (or operating cash flow) is included in our consolidated net cash provided by operating activities. In general, DGD’s members use DGD’s operating cash flow (excluding changes in its current assets and current liabilities) to fund its capital investments rather than distribute all of that cash to themselves. Because DGD’s operating cash flow is effectively attributable to each member, only 50 percent of DGD’s capital investments should be attributed to our net share of capital investments. We also exclude all of the capital expenditures of other VIEs that we consolidate because we do not operate those VIEs. See Note 12 of Notes to Consolidated Financial Statements for more information about the VIEs that we consolidate. We believe capital investments attributable to Valero is an important measure because it more accurately reflects our capital investments.

Capital investments attributable to Valero should not be considered as an alternative to capital investments, which is the most comparable GAAP measure, nor should it be considered in isolation or as a substitute for an analysis of our cash flows as reported under GAAP. In addition, this non-GAAP measure may not be comparable to similarly titled measures used by other companies because we may define it differently, which may diminish its utility.

The following table (in millions) reconciles our capital investments to capital investments attributable to Valero for the years ended December 31, 2025 and 2024.

Contractual Obligations

Below is a summary of our contractual obligations (in millions) as of December 31, 2025 that are expected to be paid within the next year and thereafter. These obligations are reflected in our balance sheets, except (i) the interest payments related to debt obligations, operating lease liabilities, and finance lease obligations and (ii) purchase obligations.

________________________

(a)Debt obligations and a maturity analysis of our debt are described in Note 9 of Notes to Consolidated Financial Statements. Debt obligations exclude amounts related to net unamortized debt issuance costs and other.

(b)Interest payments related to debt obligations are the expected payments based on information available as of December 31, 2025.

(c)Operating lease liabilities, finance lease obligations, and maturity analyses of remaining minimum lease payments are described in Note 5 of Notes to Consolidated Financial Statements. Operating lease liabilities and finance lease obligations reflected in this table include related interest expense.

(d)Other long-term liabilities are described in Note 8 of Notes to Consolidated Financial Statements. Other long-term liabilities exclude amounts related to the long-term portion of operating lease liabilities that are separately presented above.

(e)Purchase obligations are described in Note 10 of Notes to Consolidated Financial Statements. Purchase obligations are based on (i) fixed or minimum quantities to be purchased and (ii) fixed or estimated prices to be paid based on current market conditions.

In 2025, we issued $650 million of public debt and used a portion of the net proceeds to repay $440 million of our public debt that matured in 2025, as described in Note 9 of Notes to Consolidated Financial Statements.

The amount outstanding associated with the IEnova Revolver, as defined and described in Note 9 of Notes to Consolidated Financial Statements, is reflected in current portion of debt and finance lease obligations in our balance sheet as of December 31, 2025, and also included in the table above in debt obligations – short-term. The IEnova Revolver is subject to repayment on demand; however, we do not expect the lender to demand repayment during the next 12 months. Thus, the final cash flows for this instrument cannot be predicted with certainty at this time.

We have not entered into any transactions, agreements, or other contractual arrangements that would result in off-balance sheet liabilities.

Other Matters Impacting Liquidity and Capital Resources

Stock Purchase Programs

During the year ended December 31, 2025, we purchased for treasury 16,659,800 of our shares for a total cost of $2.6 billion. See Note 11 of Notes to Consolidated Financial Statements for additional information related to our stock purchase programs. 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

62

Table of Contents

expiration date, which is in addition to the amount remaining under the September 2024 Program. We will continue to evaluate the timing of purchases when appropriate. We have no obligation to make purchases under these programs.

Pension Plan Funding

During 2026, we plan to contribute approximately $70 million and $20 million to our pension plans and other postretirement benefit plans, respectively. See Note 13 of Notes to Consolidated Financial Statements for a discussion of our employee benefit plans.

Tax Matters

The OBBB

On July 4, 2025, the OBBB was enacted, which resulted in a broad range of changes to the Code, as more fully described in Note 15 of Notes to Consolidated Financial Statements. These changes and other provisions of this legislation did not have a material effect on our financial condition, results of operations, and liquidity in 2025. However, certain provisions of this legislation become effective over time and may require further clarification through regulations and other guidance issued by the U.S. Department of the Treasury and the IRS. We will continue to evaluate the effects of the OBBB on our financial condition, results of operations, and liquidity in the future.

Pillar Two

The Organisation for Economic Co-operation and Development (OECD) has introduced a framework that provides for a 15 percent global minimum effective tax rate for large multinational corporations on the income arising in each jurisdiction where they operate, known as Pillar Two. While all OECD countries and jurisdictions have agreed to Pillar Two, the related rules are being implemented on a country-by-country basis. Certain countries in which we operate, such as Canada, the U.K., and Ireland, have enacted tax legislation to implement Pillar Two with effective dates beginning in 2024, and we are subject to the tax laws of those countries. The Pillar Two rules did not have a material effect on our financial condition, results of operations, or liquidity in 2025. On January 5, 2026, the OECD released an administrative guidance package, including a “Side-by-Side System” designed to prevent other jurisdictions from imposing tax on U.S. profits of U.S. companies. We will continue to monitor U.S. and international legislative developments to assess the potential impacts of these rules. We currently do not expect that compliance with these rules will have a material effect on our financial condition, results of operations, or liquidity in the future.

Cash Held by Our Foreign Subsidiaries

As of December 31, 2025, $4.1 billion of our cash and cash equivalents was held by our foreign subsidiaries. Cash held by our foreign subsidiaries can be repatriated to us through dividends without any U.S. federal income tax consequences, but certain other taxes may apply, including, but not limited to, withholding taxes imposed by certain foreign jurisdictions, U.S. state income taxes, and U.S. federal income tax on foreign exchange gains. Therefore, there is a cost to repatriate cash held by certain of our foreign subsidiaries to us.

Asset Retirement Obligations

See Notes 2 and 8 of Notes to Consolidated Financial Statements for information regarding our expected asset retirement obligations.

Environmental Matters

Our operations are subject to extensive environmental regulations by government authorities relating to, among other matters, the release or discharge of materials into the environment, climate, waste

63

Table of Contents

management, pollution prevention measures, GHG and other emissions, our facilities and operations, and characteristics and composition of many of our products. Because environmental laws and regulations have become more complex and stringent and new or revised environmental laws and regulations are continuously being enacted or proposed, the level of future costs and expenditures required for environmental matters could increase. See Note 1 of Notes to Consolidated Financial Statements regarding our accounting for our environmental liabilities under “Environmental Matters” and see Note 8 of Notes to Consolidated Financial Statements for disclosure of these liabilities. See also “ITEMS 1. and 2. BUSINESS AND PROPERTIES—GOVERNMENT REGULATIONS” and the items incorporated by reference therein.

Concentration of Customers

Our operations have a concentration of customers in the refining industry and customers who are refined petroleum product wholesalers and retailers. These concentrations of customers may impact our overall exposure to credit risk, either positively or negatively, in that these customers may be similarly affected by changes in economic or other conditions, including the uncertainties concerning worldwide events causing volatility in the global crude oil markets. However, we believe that our portfolio of accounts receivable is sufficiently diversified to the extent necessary to minimize potential credit risk. Historically, we have not had any significant problems collecting our accounts receivable. See also “ITEM 1A. RISK FACTORS—LEGAL, GOVERNMENT, AND REGULATORY RISKS—We are subject to risks arising from legal, regulatory, and political developments regarding climate- and environmental-related matters, or that are adverse to or restrict refining and marketing operations.”

CRITICAL ACCOUNTING ESTIMATES

The preparation of financial statements in conformity with GAAP requires us to make estimates and assumptions, which we believe to be reasonable, that affect the amounts reported in our financial statements and accompanying notes. However, actual results could differ from those estimates and assumptions. The following summary provides further information about our critical accounting policies that involve critical accounting estimates, and should be read in conjunction with Note 1 of Notes to Consolidated Financial Statements, which summarizes our significant accounting policies. The following accounting policies involve estimates that are considered critical due to the level of subjectivity and judgment involved, as well as the impact on our financial position and results of operations. Unless otherwise noted, estimates of the sensitivity to earnings that would result from changes in the assumptions used in determining our estimates are not practicable due to the number of assumptions and contingencies involved, and the wide range of possible outcomes.

Unrecognized Tax Benefits

We take tax positions in our tax returns from time to time that ultimately may not be allowed by the relevant taxing authorities. When we take such positions, we evaluate the likelihood of sustaining those positions and determine the amount of tax benefit arising from such positions, if any, that should be recognized in our financial statements. Tax benefits not recognized by us are recorded as a liability for unrecognized tax benefits, which represents our potential future obligation to various taxing authorities if the tax positions are not sustained.

The evaluation of tax positions and the determination of the benefit arising from such positions that are recognized in our financial statements requires us to make significant judgments and estimates based on an analysis of complex tax laws and regulations and related interpretations. These judgments and estimates are subject to change due to many factors, including the progress of ongoing tax audits, case law, and changes in legislation.

64

Table of Contents

Details of our changes in unrecognized tax benefits, along with other information about our unrecognized tax benefits, are included in Note 15 of Notes to Consolidated Financial Statements.

Fair Value Measurements

Fair value represents the amount that we expect to receive or pay in an orderly transaction with a market participant at the measurement date. There are three generally accepted valuation approaches for measuring the fair value of assets and liabilities: the market approach, the income approach, and the cost approach. We primarily use the market approach for fair value measurements, which is based on observable information available as of the measurement date, such as quoted prices and other relevant market data for identical or comparable assets or liabilities. The income approach estimates fair value by discounting expected future amounts into a single present value that reflects current market expectations. Fair value under the cost approach reflects the amount that would currently be required to replace the service capacity of the asset and is often referred to as current replacement cost. Regardless of the valuation approach or combination thereof utilized, fair value estimates require us to apply considerable judgment in selecting inputs, which may be observable or unobservable, and significant assumptions based on historical and industry trends and other market conditions.

As discussed in Note 2 of Notes to Consolidated Financial Statements, we concluded that the carrying values of the Benicia and Wilmington refineries were impaired as of March 31, 2025, and as a result, reduced the carrying values of these assets to their estimated fair values. These nonrecurring fair value measurements were determined using a market approach based on the best information available. See Note 19 of Notes to Consolidated Financial Statements for further details on our fair value measurements.

Impairment of Long-Lived Assets

Long-lived assets (primarily property, plant, and equipment) 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 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 recoverable, an impairment loss is recognized for the amount by which the carrying amount of the long-lived asset exceeds its fair value, with fair value determined based on the most appropriate valuation approach or combination thereof.

In order to test for recoverability, we must make estimates of projected cash flows related to the asset being evaluated. Such estimates include, but are not limited to, assumptions about future sales volumes, commodity prices, operating costs, margins, the use or disposition of the asset, the asset’s estimated remaining useful life, and future expenditures necessary to maintain the asset’s existing service potential in light of existing and expected regulations. Due to the significant subjectivity of the assumptions used to test for recoverability, changes in market and economic conditions could result in significant impairment charges in the future, thus affecting our earnings.

New environmental and tax laws and regulations, as well as changes to existing laws and regulations, are continuously being enacted or proposed. The implementation of future legislative and regulatory initiatives (such as those discussed in ITEM 1A. RISK FACTORS) that may adversely affect our operations could indicate that the carrying value of an asset may not be recoverable and result in an impairment loss that could be material. If the circumstances that trigger an impairment also result in a reduction in the estimated useful life of the asset, then we may also be required to recognize an asset retirement obligation for that asset.
