Cautionary Statement This presentation contains forward-looking statements made by Valero Energy Corporation (“VLO” or “Valero”) within the meaning of federal securities laws. These statements discuss future expectations, contain projections of results of operations or of financial condition or state other forward-looking information. You can identify forward-looking statements by words such as ”plan,” “should,” “anticipate,” “believe,” “estimate,” “expect,” “could,” “continue,” “focused,” “opportunity,” “scheduled,” “may,” “targeting,” guidance, ambition, executing, pursuing, developing, evaluating, advancing, would,“ or other similar expressions that convey the uncertainty of future events or outcomes. Forward-looking statements in this presentation include, but are not limited to, those relating to our low-carbon projects, statements relating our low-carbon fuels strategy, our 2025 and 2035 GHG emissions reduction/displacement targets, 2050 ambition, future capital expenditures, expected timing, cost and performance of projects, the effect of projects on our financial performance, future low-carbon policies and demand for low-carbon fuels, future business plans and strategies, future safety and environmental performance, future operating and financial performance, future market and industry conditions, future production and manufacturing ability and size, management of future risks and 2024 guidance, among others. These forward-looking statements are not guarantees of future performance and are subject to risks, uncertainties and other factors, some of which are beyond the control of Valero and are difficult to predict including, but not limited to, the effect, impact, potential duration or other implications of, global geopolitical and other conflicts and tensions, the impact of inflation on margins and costs, economic activity levels, market dynamics, cyberattacks, weather events, other matters affecting Valero’s operations, financial performance or the demand for Valero’s products, and the uncertainties that remain with respect to current or contemplated legal, political or regulatory developments that are adverse to or restrict refining and marketing operations, or that impose profits, windfall or margin taxes or penalties, and the adverse effects the foregoing may have on Valero's business plan, strategy, operations and financial performance. These statements are often based upon various assumptions, many of which are based, in turn, upon further assumptions, including examination of historical operating trends made by the management of Valero. Although Valero believes that the assumptions were reasonable when made, because assumptions are inherently subject to significant uncertainties and contingencies, which are difficult or impossible to predict and are beyond its control, Valero cannot give assurance that it will achieve or accomplish its expectations, beliefs or intentions. When considering these forward-looking statements, you should keep in mind the risk factors and other cautionary statements contained in Valero’s filings with the Securities and Exchange Commission, including Valero’s annual report on Form 10-K, quarterly reports on Form 10-Q, and other reports available on Valero’s website at www.valero.com. These risks could cause the actual results of Valero to differ materially from those contained in any forward-looking statement. This presentation includes certain financial measures that are not defined under U.S. Generally Accepted Accounting Principles (GAAP) and are considered to be non-GAAP measures. Valero has defined these non-GAAP measures and believes they are useful to the external users of its financial statements, including industry analysts, investors, lenders, and rating agencies. Valero believes these measures are useful to assess its ongoing financial performance because, when reconciled to their most comparable U.S. GAAP measures, they provide improved comparability between periods after adjusting for certain items that Valero believes are not indicative of its core operating performance and that may obscure its underlying business results and trends. These non-GAAP measures should not be considered as alternatives to their most comparable U.S. GAAP measures nor should they be considered in isolation or as a substitute for an analysis of Valero’s results of operations as reported under U.S. GAAP. In addition, these non-GAAP measures may not be comparable to similarly titled measures used by other companies because Valero may define them differently, which diminishes their utility. Valero’s reconciliations of GAAP financial measures to non-GAAP financial measures are located at the end of this presentation. See also slides 42-44.

Expanding our competitive advantage with sustainable aviation fuel (SAF) DGD Port Arthur SAF Project • Large-scale SAF project at the recently constructed DGD Port Arthur plant is expected to be completed in the fourth quarter of 2024 − The plant will have the capability to upgrade up to 50% of its current renewable diesel production capacity to SAF, or ~235 million gallons per year − The project’s estimated cost is $315 million, with half of that attributable to Valero − Project scope includes a heater, a fractionation unit to separate the SAF and renewable diesel product streams and additional product tankage • Project is expected to exceed our minimum return threshold of an after-tax IRR of 25% − Under the Inflation Reduction Act (IRA), SAF is expected to receive a higher Clean Fuel Production Credit value than renewable diesel, resulting in higher margin for SAF production • Valero is independently evaluating an Ethanol-to-Jet process that would convert ethanol from our ethanol plants that have carbon sequestration capability to SAF See slides 42-44 for notes regarding this slide.

But the more batteries you use, the more weight you add—and the more to delivery power you need. Even with big breakthroughs in battery technology, electric vehicles will probably never be a 4 practical solution for things like 18-wheelers, cargo ships, and passenger jets.

Pages 4- 5 and 29-30 of our 2022 TCFD Report contain additional information on the independent third-party analysis, and the notes near the end of our 2022 TCFD Report contain additional information on our value chain analysis. Slides 6 and 17 Free cash flow is defined as net cash provided by operating activities less capital expenditures of VLO and DGD, deferred turnaround and catalyst cost expenditures, investments in joint ventures, and changes in current assets and liabilities. Average free cash flow reflects 2012 through the most recent annual filing. Average free cash flow as a percentage of market cap for PBF reflects years 2013 to 2023 due to its December 2012 IPO. Volatility expressed as coefficient of variance, or the standard deviation divided by the mean, of the respective metric on a quarterly basis from the first quarter of 2012 through the fourth quarter of 2023. EBITDA is net income (loss) before depreciation and amortization expense, “interest and debt expense, net of capitalized interest”, income tax expense (benefit), and income (loss) from discontinued operations. Refining peer group includes PSX, MPC, DINO, and PBF. Oil majors include XOM, CVX, COP and EOG. Slides 8 and 28 Amounts shown for annual EBITDA represent targeted or estimated EBITDA growth or contribution. Valero is unable to provide a reconciliation of such forward-looking measures because certain information needed to make a reasonable forward-looking estimate and reconciliation is difficult to estimate and dependent on future events, which are uncertain or outside of its control, including with respect to unknown financing terms, project timing and costs, and other potential future variables that are not known or reasonably estimable at this time. Accordingly, a reconciliation is not available without unreasonable effort. Such forward-looking non-GAAP measures are estimated consistent with the relevant definitions and assumptions. Amounts shown for stronger market environment and system optimization & strategic growth projects under the refining margin table reflect the estimated impact of revenue net of costs of goods sold.

Notes Slide 8 Texas City Crude Flexibility: Upgraded crude receipt and tankage logistics to increase the number of crude segregations and allow import and processing of discounted crude oils. Port Arthur Butane Rail Rack: Added railcar LPG loading and unloading rack, associated rail track, and LPG tankage at Port Arthur refinery to allow import of excess butane from some of our other refineries during summer months for storage at Fannett Wells and export of butane during the winter months. Import / export allows capture of seasonal arbitrage and avoids third party storage or sales. St. Charles Gasoline Blender: Installed a state-of-the-art gasoline blend system with online analyzers for blend optimization. Project provides the capability to blend additional grades (RBOB and export grades) and minimizes gasoline quality (octane, RVP) giveaway. Slide 10 DGD expects to produce synthetic paraffinic kerosene (SPK), a renewable blending component, using the Hydrotreated Esters and Fatty Acids (HEFA) process. SPK is also commonly referred to as “SAF” or “neat SAF.” Current aviation regulations allow SPK to be blended up to 50 percent with conventional jet fuel for use in an aircraft. This blend is commonly referred to as “SAF” or “blended SAF.” This document refers to both SPK and blended SAF as SAF. Slide 13 Targeted net debt-to-cap ratio based on total debt reduced by balance sheet cash. Peer group includes PSX, MPC, DINO, and PBF. Payout ratio is the sum of dividends and stock buybacks divided by adjusted net cash provided by operating activities.

Non-GAAP Disclosures Return on Invested Capital (ROIC) VLO defines return on invested capital (ROIC) as adjusted net income (loss) attributable to VLO stockholders before adjusted net interest expense after-tax, divided by average adjusted invested capital. VLO defines adjusted net income attributable to VLO as net income (loss) attributable to VLO stockholders adjusted for the after-tax effect of special items attributable to VLO that VLO believes are not indicative of its core operating performance and that may obscure VLO’s underlying business results and trends (see corresponding earnings release for each year). VLO defines adjusted net interest expense as “interest and debt expense, net of capitalized interest” adjusted to exclude “interest and debt expense, net of capitalized interest” attributable to noncontrolling interests. The income tax effect of adjusted net interest expense is estimated based on the U.S. statutory income tax rate for the respective annual period. Average adjusted invested capital is defined as the average of total adjusted invested capital for the current annual period and total adjusted invested capital for the prior annual period. VLO defines total adjusted invested capital as debt attributable to VLO, plus VLO stockholders’ equity less adjusted cash and cash equivalents. Debt attributable to VLO is defined as the current portion of debt and finance lease obligations, plus “debt and finance lease obligations, less current portion”, less total debt and finance lease obligations attributable to consolidated VIEs. Debt attributable to VLO for the year ended December 31, 2014 includes an adjustment to reflect the retrospective adoption of ASU No. 2015- 15 subtopic 835-30, which resulted in the reclassification of certain debt issuance costs from “deferred charges and other assets, net” to “debt and finance lease obligations, less current portion.” Adjusted cash and cash equivalents is defined as cash and cash equivalents adjusted to exclude cash and cash equivalents of consolidated VIEs. Debt and cash attributable to consolidated VIEs are excluded because amounts are only available to fund the operations of the VIEs and the creditors do not have recourse against VLO. Free Cash Flow VLO defines free cash flow as net cash provided by operating activities less capital expenditures of VLO and DGD, deferred turnaround and catalyst cost expenditures, investments in joint ventures, and changes in current assets and liabilities. VLO believes that the presentation of free cash flow provides useful information to investors in assessing VLO’s ability to cover ongoing costs and VLO’s ability to generate cash returns to stockholders. The GAAP measures most directly comparable to free cash flow are net cash provided by operating activities and net cash used in investing activities. Refining Segment Adjusted EBITDA per Barrel Refining segment adjusted EBITDA is defined as Refining segment operating income (loss) excluding depreciation and amortization expense and the effect of special items that VLO believes are not indicative of its core operating performance and that may obscure VLO’s underlying business results, trends and comparability between periods. Refining segment adjusted EBITDA per barrel is annual Refining segment adjusted EBITDA divided by refinery throughput volume for the period. Throughput volumes are calculated by multiplying throughput volumes per day by the number of days in the applicable period. Refining Margin Refining margin is defined as Refining segment operating income excluding the asset impairment loss, operating expenses (excluding depreciation and amortization expense), depreciation and amortization expense, and other operating expenses. We believe Refining margin is an important measure of our Refining segment’s operating and financial performance as it is the most comparable measure to the industry’s market reference product margins, which are used by industry analysts, investors, and others to evaluate our performance.

Non-GAAP Disclosures Renewable Diesel Net Cumulative Cash Flow VLO defines renewable diesel net cumulative cash flow as DGD’s cumulative adjusted EBITDA attributable to VLO, less DGD’s cumulative capital expenditures attributable to VLO. VLO defines DGD’s adjusted EBITDA attributable to VLO as 50 percent (VLO’s ownership interest) of DGD’s operating income (loss) before depreciation and amortization expense, adjusted for the effect of special items that VLO believes are not indicative of DGD's core operating performance and that may obscure underlying business results, trends, and comparability between the periods. VLO defines DGD’s capital expenditures attributable to VLO as 50 percent of DGD’s capital investments. Because DGD’s net cash flow is effectively attributable to each joint venture member, only 50 percent of DGD’s adjusted EBITDA and capital expenditures should be attributed to VLO’s renewable diesel cash flow. Therefore, renewable diesel cash flow has been adjusted for the portion of DGD’s adjusted EBITDA and capital expenditures attributable to VLO’s joint venture member’s ownership interest because VLO believes that it more accurately reflects cash flow generated by its renewable diesel segment. Ethanol Segment Adjusted EBITDA per Gallon Ethanol segment adjusted EBITDA is defined as Ethanol segment operating income excluding depreciation and amortization expense, adjusted for the effect of special items that VLO believes are not indicative of its core operating performance and that may obscure underlying business results and trends. VLO believes adjusting for these items provides improved comparability between periods. Ethanol segment adjusted EBITDA per gallon is Ethanol segment adjusted EBITDA divided by ethanol production volume for the period. Production volumes are calculated by multiplying production volumes per day by the number of days in the applicable period. Capital Investments Attributable to Valero VLO defines capital investments attributable to Valero as all capital expenditures, deferred turnaround and catalyst cost expenditures, and investments in non-consolidated joint ventures presented in VLO’s consolidated statements of cash flows excluding the portion of DGD’s capital investments attributable to the other joint venture member and all of the capital expenditures of other VIEs. Capital investments attributable to Valero are allocated between sustaining capital expenditures attributable to Valero and growth capital investments attributable to Valero. 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 VLO’s net share of capital investments. VLO also excludes the capital expenditures of other consolidated VIEs because VLO does not operate those VIEs. VLO believes that capital investments attributable to Valero is an important measure because it more accurately reflects capital investments of VLO.

Non-GAAP Disclosures Adjusted Net Cash Provided by Operating Activities VLO defines adjusted net cash provided by operating activities as net cash provided by operating activities excluding the items noted below. VLO believes adjusted net cash provided by operating activities is an important measure of its ongoing financial performance to better assess its ability to generate cash to fund VLO’s investing and financing activities. The basis for VLO’s belief with respect to each excluded item is provided below. • Changes in current assets and current liabilities – Current assets net of current liabilities represents VLO’s operating liquidity. VLO believes that the change in its operating liquidity from period to period does not represent cash generated by VLO’s operations that is available to fund VLO’s investing and financing activities. • DGD’s adjusted net cash provided by operating activities attributable to the other joint venture member’s ownership interest in DGD – VLO is a 50 percent joint venture member in DGD and consolidates DGD’s financial statements; as a result, all of DGD’s net cash provided by operating activities (or operating cash flow) is included in VLO’s consolidated net cash provided by operating activities. 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. Nevertheless, DGD’s operating cash flow is effectively attributable to each member and only 50 percent of DGD’s operating cash flow should be attributed to VLO’s net cash provided by operating activities. Therefore, net cash provided by operating activities has been adjusted for the portion of DGD’s operating cash flow attributable to the other joint venture member’s ownership interest because VLO believes that it more accurately reflects the operating cash flow available to VLO to fund VLO’s investing and financing activities. Return on Invested Capital (ROIC) Including Amounts Attributable to the Other Joint Venture Members VLO defines ROIC including amounts attributable to the other joint venture members as adjusted net income (loss) before net interest expense after-tax divided by average invested capital. VLO defines adjusted net income (loss) as net income (loss) adjusted for the after-tax effect of special items that VLO believes are not indicative of its core operating performance and that may obscure VLO’s underlying business results, trends and comparability between periods (see corresponding earnings release for each year). Net income (loss) reflects VLO consolidated earnings prior to the exclusion of net income (loss) attributable to noncontrolling interests. The after-tax effect of special items includes the effect of special items that are attributable to the other joint venture members. The income tax effect of net interest expense is estimated based on the U.S. statutory income tax rate for the respective annual period. Average invested capital is defined as the average of total invested capital for the current annual period and total invested capital for the prior annual period. VLO defines total invested capital as debt plus total equity less cash and cash equivalents. Adjusted Return on Equity (ROE) Attributable to Valero VLO defines adjusted ROE attributable to Valero as adjusted net income (loss) attributable to VLO stockholders divided by average VLO stockholders’ equity. VLO defines adjusted net income (loss) attributable to VLO stockholders as net income (loss) attributable to VLO stockholders adjusted for the after-tax effect of special items attributable to VLO stockholders that VLO believes are not indicative of its core operating performance and that may obscure VLO’s underlying business results, trends and comparability between periods (see corresponding earnings release for each year). Average VLO stockholders’ equity is defined as the average of total VLO stockholders’ equity for the current annual period and total VLO stockholders’ equity for the prior annual period. VLO stockholders’ equity reflects stockholders’ equity prior to the inclusion of equity attributable to noncontrolling interests. I N V E S T O R P R E S E N T A T I O N | M A Y 2 0 2 4 47

Non-GAAP Disclosures DGD Adjusted EBITDA per Gallon DGD adjusted EBITDA is defined as DGD’s operating income (loss) excluding depreciation and amortization expense, adjusted for the effect of special items that VLO believes are not indicative of DGD's core operating performance and that may obscure underlying business results, trends, and comparability between periods. DGD adjusted EBITDA per gallon is DGD adjusted EBITDA divided by DGD’s sales volume for the period. Sales volumes are calculated by multiplying sales volumes per day by the number of days in the applicable period. Adjusted EBITDA VLO defines EBITDA as net income (loss) before depreciation and amortization expense, “interest and debt expense, net of capitalized interest”, income tax expense (benefit), and income (loss) from discontinued operations. VLO defines adjusted EBITDA as EBITDA further adjusted for the effect of special items that VLO believes are not indicative of its core operating performance and that may obscure VLO’s underlying business results and trends. VLO believes that the presentation of adjusted EBITDA provides useful information to investors to assess its ongoing financial performance because when reconciled to net income, it provides improved comparability between periods. The U.S. GAAP measures most directly comparable to adjusted EBITDA are net income and net cash provided by operating activities. I N V E S T O R P R E S E N T A T I O N | M A Y 2 0 2 4 48
