1.    BASIS OF PRESENTATION AND SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation

General

The terms “Valero,” “we,” “our,” and “us,” as used in this report, may refer to Valero Energy Corporation, one or more of its consolidated subsidiaries, or all of them taken as a whole. The term “DGD,” as used in this report, may refer to Diamond Green Diesel Holdings LLC, its wholly owned consolidated subsidiary — Diamond Green Diesel LLC, or both of them taken as a whole.

These unaudited financial statements have been prepared in accordance with United States (U.S.) generally accepted accounting principles (GAAP) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X of the Securities Exchange Act of 1934. Accordingly, they do not include all of the information and notes required by U.S. GAAP for complete financial statements. In the opinion of management, all adjustments considered necessary for a fair presentation of our results for the nine months ended September 30, 2021 have been included. All such adjustments are of a normal recurring nature unless disclosed otherwise. Operating results for the nine months ended September 30, 2021 are not necessarily indicative of the results that may be expected for the year ending December 31, 2021. The financial statements presented herein should be read in conjunction with the financial statements included in our annual report on Form 10-K for the year ended December 31, 2020.

The balance sheet as of December 31, 2020 has been derived from our audited financial statements as of that date. For further information, refer to our financial statements and notes thereto included in our annual report on Form 10-K for the year ended December 31, 2020.

Significant Accounting Policies

Use of Estimates

The preparation of financial statements in conformity with U.S. GAAP requires us to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates. On an ongoing basis, we review our estimates based on currently available information. Changes in facts and circumstances may result in revised estimates.

Adoption of Accounting Pronouncement

The following Financial Accounting Standards Board (FASB) Accounting Standards Update (ASU) was issued and adopted by us on January 7, 2021. Our adoption of this ASU did not have a material impact on our financial statements or related disclosures.

2.    UNCERTAINTIES

At the onset of the COVID-19 pandemic in March 2020, governmental authorities around the world imposed restrictions, such as stay-at-home orders and other social distancing measures, to slow the spread of COVID-19. These measures resulted in significant economic disruption globally as reduced economic

7

VALERO ENERGY CORPORATION

CONDENSED NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

activity negatively impacted many businesses, including our business. We experienced a decline in the demand for most of the transportation fuels that we produce and sell, and thus also a decline in the market prices of those products, due to a decrease in the level of individual movement and travel resulting from the restrictions and general public health concerns. Some governmental authorities began lifting restrictions in the latter part of 2020 and this has continued throughout the first nine months of 2021. These actions have contributed to increasing levels of individual movement and travel and a resulting increase in the demand for and market prices of our products. However, some governmental authorities continue to impose some level of restrictions due in part to new outbreaks, including those related to new variants of the COVID-19 virus.

The distribution of vaccines beginning in late 2020 has helped decrease rates of infection and contributed to the lifting of many restrictions. The ongoing distribution of vaccines may result in the continued lifting of restrictions globally and may be seen as a key factor contributing to the ongoing restoration of public confidence, and thus also to stimulating and increasing global economic activity. However, the risk remains that vaccines may not be distributed widely on a timely basis, they may not be as effective against new variants of the virus, the distribution of some or all of the vaccines may be paused or withdrawn due to concerns with potential side effects, and/or the level of individuals’ willingness to receive a vaccine may not be as strong or as timely as needed. Additionally, many governmental authorities have recently announced requirements and mandates, including steep fines for non-compliance, on employers concerning workforce vaccination and testing. Many large companies across the globe, independent of such government regulations, have also begun implementing vaccine requirements and mandates for their workforce, or as a prerequisite to providing customers certain goods and services in person. These requirements and mandates have evoked mixed reactions and have created additional challenges and costs, both administratively and operationally, for employers and employees. Developments with respect to such requirements and mandates are evolving at a rapid pace and the ultimate impact thereof remains uncertain.

Based on these and other circumstances that cannot be predicted, the broader implications of the pandemic on our results of operations and financial position remain uncertain and may continue to be significant. We believe we have proactively responded to many of the known impacts of the pandemic on our business to the extent practicable and we strive to continue to do so, but there can be no assurance that these or other measures will be fully effective.

3.    INVENTORIES

Inventories consisted of the following (in millions):

	September 30, 2021		December 31, 2020
Refinery feedstocks	$	1,646	$	1,979
Refined petroleum products and blendstocks	3,944		3,425
Renewable diesel feedstocks and products	113		50
Ethanol feedstocks and products	233		297
Materials and supplies	291		287
Inventories	$	6,227	$	6,038

8

VALERO ENERGY CORPORATION

CONDENSED NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

We compare the market value of inventories to their cost on an aggregate basis, excluding materials and supplies. In determining the market value of our inventories, we assume that feedstocks are converted into refined products, which requires us to make estimates regarding the refined products expected to be produced from those feedstocks and the conversion costs required to convert those feedstocks into refined products. We also estimate the usual and customary transportation costs required to move the inventory from our plants to the appropriate points of sale. We then apply an estimated selling price to our inventories. If the aggregate market value is less than the aggregate cost, we recognize a loss for the difference in our statements of income. To the extent the aggregate market value of our last-in, first-out (LIFO) inventories subsequently increases, we recognize an increase to the value of our inventories (not to exceed cost) and a gain in our statements of income.

The market value of our LIFO inventories fell below their LIFO inventory carrying amounts as of March 31, 2020, and as a result, we recorded an LCM inventory valuation reserve of $2.5 billion in order to state our inventories at market. As of September 30, 2020, we reevaluated our inventories and determined that our cost was lower than market. As a result, our LCM inventory valuation reserve was fully reversed as of September 30, 2020. The change in our LCM inventory valuation reserve resulted in a net benefit of $313 million during the three months ended September 30, 2020. The net benefit of $19 million for the nine months ended September 30, 2020 was due to the foreign currency translation effect of the portion of the LCM inventory valuation adjustment attributable to our international operations. As of September 30, 2021 and December 31, 2020, the replacement cost (market value) of LIFO inventories exceeded their LIFO carrying amounts by $5.2 billion and $1.3 billion, respectively.

During the three and nine months ended September 30, 2020, we recognized the impact of an expected liquidation of LIFO inventory layers that increased cost of materials and other by $326 million. Our LIFO inventory levels decreased throughout the first nine months of 2020 due to lower production resulting from lower demand for our products caused by the negative economic impacts of the COVID-19 pandemic on our business. Consequently, we expected our LIFO inventory levels as of December 31, 2020 would remain below their December 31, 2019 levels.

Our non-LIFO inventories accounted for $1.2 billion and $918 million of our total inventories as of September 30, 2021 and December 31, 2020, respectively.

4.    PROPERTY, PLANT, AND EQUIPMENT

In September 2021 and 2020, we reduced the estimated useful lives of our ethanol plants in Jefferson, Wisconsin and Riga, Michigan, respectively, which reduced their net book values to estimated salvage value. The additional depreciation expense for the three and nine months ended September 30, 2021 and 2020 of $48 million and $30 million, respectively, resulting from these changes did not have a material impact on our results of operations nor was there a material impact to our financial position.

The Jefferson plant was temporarily idled in 2020 at the onset of the COVID-19 pandemic in response to the decreased demand for ethanol resulting from the effects of the pandemic on our business, and we had previously evaluated this plant for potential impairment assuming that operations would resume. However, we completed an evaluation of the plant during the third quarter of 2021 and concluded that it

VALERO ENERGY CORPORATION

CONDENSED NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

was no longer a strategic asset for our ethanol business. As a result, the plant’s operations have permanently ceased.

The Riga plant was temporarily idled in 2019 due to corn quality issues with the local third-party corn feedstock supply. Although we expected operations to resume after an improved corn harvest, we completed an evaluation of this plant during the third quarter of 2020 and concluded that it was no longer a strategic asset for our ethanol business. The plant’s operations permanently ceased at that time.

5.    DEBT

Public Debt

In September 2021, we redeemed our Floating Rate Senior Notes due September 15, 2023 (the Floating Rate Notes) for $575 million, or 100.00 percent of stated value, plus accrued and unpaid interest.

Outstanding borrowings under the DGD Revolver generally bear interest, at DGD’s option, at either (i) an alternate base rate plus the applicable margin or (ii) an adjusted LIBOR rate for the applicable interest period in effect from time to time plus the applicable margin. The DGD Revolver also requires payments for customary fees, including unused commitment fees, letter of credit fees, and administrative agent fees. As of September 30, 2021, the variable interest rate on the DGD Revolver was 1.840 percent.

IEnova Revolver

In May 2021, the borrowing capacity under the IEnova Revolver was increased from $660 million to $743 million.

7.    VARIABLE INTEREST ENTITIES

Consolidated VIEs

We consolidate a VIE when we have a variable interest in an entity for which we are the primary beneficiary. As of September 30, 2021, our significant consolidated VIEs included:

•DGD, a joint venture with a subsidiary of Darling Ingredients Inc., which owns and operates a plant that processes rendered and recycled materials, including animal fats, used cooking oils, and other vegetable oils, into renewable diesel; and

•Central Mexico Terminals, which is a collective group of three subsidiaries of Infraestructura Energetica Nova, S.A.B. de C.V. (IEnova), a Mexican company and subsidiary of Sempra Energy, a U.S. public company. We have terminaling agreements with Central Mexico Terminals that represent variable interests. We do not have an ownership interest in Central Mexico Terminals.

The assets of our VIEs can only be used to settle their own obligations and the creditors of our VIEs have no recourse to our other assets. We do not provide financial guarantees to our VIEs. Although we have provided credit facilities to some of our VIEs in support of their construction or acquisition activities, these transactions are eliminated in consolidation. Our financial position, results of operations, and cash flows are impacted by the performance of our consolidated VIEs, net of intercompany eliminations, to the extent of our ownership interest in each VIE.

The following tables present summarized balance sheet information for the significant assets and liabilities of our consolidated VIEs, which are included in our balance sheets (in millions):

Non-Consolidated VIEs

We hold variable interests in VIEs that have not been consolidated because we are not considered the primary beneficiary. These non-consolidated VIEs are not material to our financial position or results of operations and are accounted for as equity investments.

On April 19, 2021, we sold a 24.99 percent membership interest in MVP, an unconsolidated joint venture with a subsidiary of Magellan Midstream Partners, L.P. (Magellan), for $270 million that resulted in a gain of $62 million, which is included in “other income, net.” MVP owns and operates a marine terminal located adjacent to the Houston Ship Channel in Pasadena, Texas. We retained a 25.01 percent membership interest in MVP.

As previously disclosed in our annual report on Form 10-K for the year ended December 31, 2020, we plan to contribute approximately $128 million to our pension plans and $22 million to our other postretirement benefit plans during 2021. During the nine months ended September 30, 2021, we contributed $121 million and $12 million to our pension and other postretirement benefit plans, respectively. During the nine months ended September 30, 2020, we contributed $28 million and $12 million to our pension and other postretirement benefit plans, respectively.

9.    INCOME TAXES

Our income tax expense for the three and nine months ended September 30, 2021 included a permanent income tax benefit to our estimated annual effective tax rate from DGD’s share of pre-tax income that is not taxable to us and a benefit for the settlement of the audits of certain state tax returns for 2004 through 2006. In addition, income tax expense for the nine months ended September 30, 2021 included a $64 million charge, which resulted from certain statutory income tax rate changes (primarily an increase in the United Kingdom (U.K.) rate from 19 percent to 25 percent effective in 2023) that were enacted during the three months ended June 30, 2021. The variation in the customary relationship of our effective tax rate to the U.S. federal statutory rate for the three and nine months ended September 30, 2021 was primarily due to these components of our tax expense.

On March 27, 2020, the Coronavirus Aid, Relief and Economic Security (CARES) Act was enacted, which resulted in significant changes to the U.S. Internal Revenue Code of 1986, as amended. Our income tax benefit for the three and nine months ended September 30, 2020, therefore, included a tax benefit of $121 million and $238 million, respectively, attributable to the carryback of our 2020 tax net operating loss (NOL) to our 2015 income tax year when we paid U.S. federal income taxes at a 35 percent tax rate. The variation in the customary relationship of our effective tax rate to the U.S. federal statutory rate for the three and nine months ended September 30, 2020 was primarily due to this income tax benefit.

11.    REVENUES AND SEGMENT INFORMATION

Revenue from Contracts with Customers

Disaggregation of Revenue

Revenue is presented in the table below under “Segment Information” disaggregated by product because this is the level of disaggregation that management has determined to be beneficial to users of our financial statements.

Contract Balances

Contract balances were as follows (in millions):

	September 30, 2021		December 31, 2020
Receivables from contracts with customers, included in receivables, net	$	5,597	$	3,642
Contract liabilities, included in accrued expenses	67		55

During the nine months ended September 30, 2021 and 2020, we recognized as revenue $44 million and $53 million that was included in contract liabilities as of December 31, 2020 and 2019, respectively. Revenue recognized during the three months ended September 30, 2021 and 2020 related to contract liabilities was not material.

Remaining Performance Obligations

We have spot and term contracts with customers, the majority of which are spot contracts with no remaining performance obligations. We do not disclose remaining performance obligations for contracts that have terms of one year or less. The transaction price for our remaining term contracts includes a fixed component and variable consideration (i.e., a commodity price), both of which are allocated entirely to a wholly unsatisfied promise to transfer a distinct good that forms part of a single performance obligation. The fixed component is not material and the variable consideration is highly uncertain. Therefore, as of September 30, 2021, we have not disclosed the aggregate amount of the transaction price allocated to our remaining performance obligations.

Segment Information

We have three reportable segments — refining, renewable diesel, and ethanol. Each segment is a strategic business unit that offers different products and services by employing unique technologies and marketing strategies and whose operations and operating performance are managed and evaluated separately. Operating performance is measured based on the operating income generated by the segment, which includes revenues and expenses that are directly attributable to the management of the respective segment. Intersegment sales are generally derived from transactions made at prevailing market rates. The following is a description of each segment’s business operations.

•The refining segment includes the operations of our petroleum refineries, the associated marketing activities, and logistics assets that support our refining operations. The principal products manufactured by our refineries and sold by this segment include gasolines and blendstocks, distillates, and other products.

VALERO ENERGY CORPORATION

CONDENSED NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

•The renewable diesel segment represents the operations of DGD, our consolidated joint venture as discussed in Note 7. The principal product manufactured by DGD and sold by this segment is renewable diesel. This segment sells some renewable diesel to the refining segment, which is then sold to that segment’s customers.

•The ethanol segment includes the operations of our ethanol plants, the associated marketing activities, and logistics assets that support our ethanol operations. The principal products manufactured by our ethanol plants are ethanol and distillers grains. This segment sells some ethanol to the refining segment for blending into gasoline, which is sold to that segment’s customers as a finished gasoline product.

Operations that are not included in any of the reportable segments are included in the corporate category.

In order to determine net cash provided by operating activities, net income (loss) is adjusted by, among other things, changes in current assets and current liabilities as follows (in millions):

	Nine Months Ended September 30,
	2021		2020
Decrease (increase) in current assets:
Receivables, net	$	(2,643)	$	3,229
Inventories	(232)		1,577
Prepaid expenses and other	28		70
Increase (decrease) in current liabilities:
Accounts payable	3,624		(4,893)
Accrued expenses	538		17
Taxes other than income taxes payable	200		(24)
Income taxes payable	115		(208)
Changes in current assets and current liabilities	$	1,630	$	(232)

Changes in current assets and current liabilities for the nine months ended September 30, 2021 were primarily due to the following:

•the increase in receivables was primarily due to an increase in refined petroleum product prices in September 2021 compared to December 2020 combined with an increase in refined petroleum product sales volumes, partially offset by a decrease in income taxes receivable associated with the receipt of a $962 million refund related to our U.S federal income tax return for 2020;

•the increase in accounts payable was primarily due to an increase in crude oil and other feedstock prices in September 2021 compared to December 2020 combined with an increase in crude oil and other feedstock volumes purchased; and

•the increase in accrued expenses was primarily due to an increase in our environmental credit obligations under fixed-price contracts that resulted from higher prices for Renewable Identification Numbers (RINs) in September 2021 compared to December 2020.

Changes in current assets and current liabilities for the nine months ended September 30, 2020 were primarily due to the following:

•the decrease in receivables was due to (i) a decrease of $3.6 billion as a result of a decrease in sales volumes combined with a decrease in refined petroleum product prices in September 2020 compared to December 2019 and (ii) the collection of $449 million for a blender’s tax credit receivable attributable to volumes blended during 2019 and 2018, partially offset by an increase in income taxes receivable of $770 million primarily due to the recognition of a current income tax benefit;

•the decrease in inventories was primarily due to lower inventory levels in September 2020 compared to December 2019; and

•the decrease in accounts payable was due to a decrease in crude oil and other feedstock volumes purchased combined with a decrease in crude oil and other feedstock prices in September 2020 compared to December 2019.

A description of our assets and liabilities recognized at fair value along with the valuation methods and inputs we used to develop their fair value measurements are as follows:

•Commodity derivative contracts consist primarily of exchange-traded futures, which are used to reduce the impact of price volatility on our results of operations and cash flows as discussed in Note 14. These contracts are measured at fair value using a market approach based on quoted prices from the commodity exchange and are categorized in Level 1 of the fair value hierarchy.

•Physical purchase contracts represent the fair value of fixed-price corn purchase contracts. The fair values of these purchase contracts are measured using a market approach based on quoted prices from the commodity exchange or an independent pricing service and are categorized in Level 2 of the fair value hierarchy.

•Foreign currency contracts consist of foreign currency exchange and purchase contracts and foreign currency swap agreements related to our international operations to manage our exposure to exchange rate fluctuations on transactions denominated in currencies other than the local (functional) currencies of our operations. These contracts are valued based on quoted foreign currency exchange rates and are categorized in Level 1 of the fair value hierarchy.

•Investments of certain benefit plans consist of investment securities held by trusts for the purpose of satisfying a portion of our obligations under certain U.S. nonqualified benefit plans. The plan assets categorized in Level 1 of the fair value hierarchy are measured at fair value using a market approach based on quoted prices from national securities exchanges. The plan assets categorized

27

VALERO ENERGY CORPORATION

CONDENSED NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

in Level 3 of the fair value hierarchy represent insurance contracts, the fair value of which is provided by the insurer.

•Environmental credit obligations represent our liability for the purchase of (i) biofuel credits (primarily RINs in the U.S.) needed to satisfy our blending obligation under the U.S. federal Renewable Fuel Standard (RFS) and similar biofuel blending programs, such as the U.K. Renewable Transport Fuel Obligation, (collectively, the biofuels programs); and (ii) emission credits needed under various other environmental emissions programs (collectively, the other environmental emissions programs). To the degree we are unable to blend biofuels (such as ethanol and biodiesel, including renewable diesel) at percentages required under the biofuel programs, we must purchase biofuel credits to comply with these programs. Under the other environmental emissions programs, we also must purchase emission credits to comply with these programs. These programs are described in Note 14 under “Risk Management Activities by Type of Risk—Environmental Compliance Program Price Risk.” The liability for environmental credits is based on our deficit for such credits as of the balance sheet date, if any, after considering any credits acquired or under contract, and is equal to the product of the credits deficit and the market price of these credits as of the balance sheet date. The environmental credit obligations are categorized in Level 2 of the fair value hierarchy and are measured at fair value using a market approach based on quoted prices from an independent pricing service.

Nonrecurring Fair Value Measurements

There were no assets or liabilities that were measured at fair value on a nonrecurring basis as of September 30, 2021 and December 31, 2020.

Other Financial Instruments

Financial instruments that we recognize in our balance sheets at their carrying amounts are shown in the following table along with their associated fair values (in millions):

14.    PRICE RISK MANAGEMENT ACTIVITIES

General

We are exposed to market risks primarily related to the volatility in the price of commodities, foreign currency exchange rates, and the price of credits needed to comply with various government and regulatory programs. We enter into derivative instruments to manage some of these risks, including derivative instruments related to the various commodities we purchase or produce, and foreign currency exchange and purchase contracts, as described below under “Risk Management Activities by Type of Risk.” These derivative instruments are recorded as either assets or liabilities measured at their fair values (see Note 13), as summarized below under “Fair Values of Derivative Instruments.” The effect of these derivative instruments on our income and other comprehensive income (loss) is summarized below under “Effect of Derivative Instruments on Income and Other Comprehensive Income (Loss).”

Risk Management Activities by Type of Risk

Commodity Price Risk

We are exposed to market risks related to the volatility in the price of feedstocks (primarily crude oil and corn), the products we produce (primarily refined petroleum products), 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, such as futures and options. 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 has been approved by our board of directors.

We primarily use commodity derivative instruments as cash flow hedges and economic hedges. Our objectives for entering into each type of hedge is described below.

•Cash flow hedges – The objective of our cash flow hedges is to lock in the price of forecasted purchases and/or product sales at existing market prices that we deem favorable.

•Economic hedges – Our objectives for holding economic hedges are to (i) manage price volatility in certain feedstock and product inventories and (ii) lock in the price of forecasted purchases and/or product sales at existing market prices that we deem favorable.

VALERO ENERGY CORPORATION

CONDENSED NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

As of September 30, 2021, we had the following outstanding commodity derivative instruments that were used as cash flow hedges and economic hedges, as well as commodity derivative instruments related to the physical purchase of corn at a fixed price. The information presents the notional volume of outstanding contracts by type of instrument and year of maturity (volumes in thousands of barrels, except corn contracts that are presented in thousands of bushels).

	Notional Contract Volumes by Year of Maturity
	2021	2022
Derivatives designated as cash flow hedges:
Refined petroleum products:
Futures – long	1,162	501
Futures – short	3,400	501
Derivatives designated as economic hedges:
Crude oil and refined petroleum products:
Futures – long	63,320	1,354
Futures – short	61,498	1,173
Corn:
Futures – long	85,540	1,615
Futures – short	103,295	6,395
Physical contracts – long	16,441	4,792

Foreign Currency Risk

We are exposed to exchange rate fluctuations on transactions related to our international operations that are denominated in currencies other than the local (functional) currencies of our operations. To manage our exposure to these exchange rate fluctuations, we use foreign currency contracts. These contracts are not designated as hedging instruments for accounting purposes and therefore are classified as economic hedges. As of September 30, 2021, we had foreign currency contracts to purchase $463 million of U.S. dollars and $1.1 billion of U.S. dollar equivalent Canadian dollars. Of these commitments, $425 million matured on or before October 25, 2021 and the remaining $1.138 billion will mature by December 6, 2021.

Environmental Compliance Program Price Risk

We are exposed to market risk related to the volatility in the price of credits needed to comply with various governmental and regulatory environmental compliance programs. To manage this risk, we enter into contracts to purchase these credits as appropriate. Some of these contracts are derivative instruments; however, we elect the normal purchase exception and do not record these contracts at their fair values. Certain of these programs, such as the biofuels programs described in Note 13, require us to blend biofuels into the products we produce, and we are subject to such programs in most of the countries in which we operate. These countries, or local governments thereof, set annual quotas for the percentage of biofuels that must be blended into the motor fuels consumed in their jurisdictions. As a producer of motor fuels from petroleum, we are obligated to blend biofuels into the products we produce at a rate that is at least equal to the applicable quota. To the degree we are unable to blend at the applicable rate, we must purchase biofuel credits (primarily RINs in the U.S.). We are exposed to

30

VALERO ENERGY CORPORATION

CONDENSED NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

the volatility in the market price of these credits, and we manage that risk by purchasing biofuel credits as appropriate. The cost of meeting our credit obligations under the biofuels programs was $618 million and $143 million for the three months ended September 30, 2021 and 2020, respectively, and $1.6 billion and $391 million for the nine months ended September 30, 2021 and 2020, respectively. These amounts are reflected in cost of materials and other.

We are subject to additional requirements under the other environmental emissions programs as discussed in Note 13. Under these other environmental emissions programs, we purchase various emission credits to comply with these programs. Therefore, we are exposed to the volatility in the market price of these credits. The cost of the various credits under the other environmental emissions programs are significant; however, we recovered substantially all of these costs from our customers for the three and nine months ended September 30, 2021 and 2020 and expect to continue to recover the majority of these costs in the future. For the three and nine months ended September 30, 2021 and 2020, the net cost of meeting our credit obligations under these other environmental emissions programs was immaterial.

Fair Values of Derivative Instruments

The following tables provide information about the fair values of our derivative instruments as of September 30, 2021 and December 31, 2020 (in millions) and the line items in the balance sheets in which the fair values are reflected. See Note 13 for additional information related to the fair values of our derivative instruments.

As indicated in Note 13, we net fair value amounts recognized for multiple similar derivative contracts executed with the same counterparty under master netting arrangements, including cash collateral assets and obligations. The following table, however, is presented on a gross asset and gross liability basis, which results in the reflection of certain assets in liability accounts and certain liabilities in asset accounts:

Market Risk

Our price risk management activities involve the receipt or payment of fixed price commitments into the future. These transactions give rise to market risk, which is the risk that future changes in market conditions may make an instrument less valuable. We closely monitor and manage our exposure to market risk on a daily basis in accordance with policies approved by our board of directors. Market risks are monitored by our risk control group to ensure compliance with our stated risk management policy. We do not require any collateral or other security to support derivative instruments into which we enter. We also do not have any derivative instruments that require us to maintain a minimum investment-grade credit rating.

Effect of Derivative Instruments on Income and Other Comprehensive Income (Loss)

The following table provides information about the gain (loss) recognized in income and other comprehensive income (loss) due to fair value adjustments of our cash flow hedges (in millions):

Derivatives in Cash Flow Hedging Relationships	Location of Gain (Loss) Recognized in Income on Derivatives	Three Months Ended September 30,				Nine Months Ended September 30,

For cash flow hedges, no component of any derivative instrument’s gains or losses was excluded from the assessment of hedge effectiveness for the three and nine months ended September 30, 2021 and 2020. For the three and nine months ended September 30, 2021 and 2020, cash flow hedges primarily related to forward sales of renewable diesel. The estimated deferred after-tax loss that is expected to be reclassified into revenues over the next 12 months as a result of the hedged transactions that are forecasted to occur as of September 30, 2021 was immaterial. For the three and nine months ended September 30, 2021 and 2020, there were no amounts reclassified from accumulated other comprehensive loss into income as a result of the discontinuance of cash flow hedge accounting. The changes in accumulated other comprehensive loss by component, net of tax, for the three and nine months ended September 30, 2021 and 2020 are described in Note 6.

NON-GAAP FINANCIAL MEASURES

The discussions in “OVERVIEW AND OUTLOOK,” “RESULTS OF OPERATIONS,” and “LIQUIDITY AND CAPITAL RESOURCES” below include references to financial measures that are not defined under U.S. GAAP. These non-GAAP financial measures include adjusted operating income (loss) (including adjusted operating income (loss) for each of our reportable segments, as applicable); refining, renewable diesel, and ethanol segment margin; and capital investments attributable to Valero. We have included these non-GAAP financial measures to help facilitate the comparison of operating results between periods, to help assess our cash flows, and because we believe they provide useful information as discussed further below. See the tables in note (g) beginning on page 57 for reconciliations of adjusted operating income (loss) (including adjusted operating income (loss) for each of our reportable segments, as applicable) and refining, renewable diesel, and ethanol segment margin to their most directly comparable U.S. GAAP financial measures. Also in note (g), we disclose the reasons why we believe our use of such non-GAAP financial measures provides useful information. See the table on page 64 for a reconciliation of capital investments attributable to Valero to its most directly comparable U.S. GAAP financial measure. Beginning on page 63, we disclose the reasons why we believe our use of this non-GAAP financial measure provides useful information.

IMPACT OF THE COVID-19 PANDEMIC TO OUR BUSINESS

The COVID-19 pandemic has negatively impacted our business. Although we have experienced improvements in 2021, the broader implications of the pandemic on our results of operations and financial position remain uncertain. Information about the uncertainties of the COVID-19 pandemic on our business is discussed in Note 2 of Condensed Notes to Consolidated Financial Statements.

OVERVIEW AND OUTLOOK

Overview

Business Operations Update

Our business continued to recover throughout the third quarter of 2021 as a result of ongoing improvements in the demand for and market prices of refined petroleum products, primarily gasoline and diesel, with demand for these products near pre-pandemic levels for most of the first nine months of 2021, and we have recently experienced demand for diesel well in excess of pre-pandemic levels. Jet fuel demand has also continued to improve throughout the third quarter and first nine months of 2021, although at a slower pace than other products we produce relative to pre-pandemic levels. These ongoing improvements in demand and an associated increase in refining margins contributed to us reporting net income attributable to Valero stockholders of $463 million for the third quarter of 2021.

Refining margins have improved more slowly than demand over the first nine months of 2021, although the improvement has been more significant during the third quarter of 2021 as refined product inventories continued to fall, especially in the U.S. In fact, U.S. refined product inventories are at five-year lows due to the effect of increased demand, the impact from lower production resulting from a portion of U.S. Gulf Coast refining capacity being offline in late August and most of September 2021 because of Hurricane Ida, and the impact of lower imports from Europe as rising natural gas prices in Europe have made their supply less economic. Renewable diesel margins have remained strong over the first nine months of 2021 due to continued demand for this low-carbon transportation fuel. However, our renewable diesel operations were negatively impacted during the third quarter of 2021 as a result of Hurricane Ida. We shut down two refineries and our renewable diesel plant in Louisiana in preparation for the storm, and although the refineries and the plant sustained minimal damage, we were delayed from restarting operations until electrical supply and other utilities were restored and from shipping product to our customers until the Mississippi River was reopened to ship and barge traffic.

While we reported positive earnings for the third quarter of 2021, we generated a net loss attributable to Valero stockholders of $79 million for the first nine months of 2021. The factor primarily impacting the nine-month results was a significant increase in the cost of electricity and natural gas at certain of our refineries and ethanol plants arising out of Winter Storm Uri. We incurred excess energy costs estimated at $579 million, or $467 million after taxes, in February 2021.

Our results of operations for the third quarter and the first nine months of 2021 are more fully discussed in “Third Quarter Results” and “First Nine Months Results” below and in “RESULTS OF OPERATIONS” beginning on page 41.

Despite the lingering, but improving, impacts of the pandemic on our operations, the negative effects arising out of Winter Storm Uri on energy costs at certain of our refineries and ethanol plants, and the negative effects of Hurricane Ida on our renewable diesel operations, our operations generated $3.4 billion of cash during the first nine months of 2021. Approximately a quarter of that amount, however, was due to the receipt of our 2020 U.S. federal income tax refund of $962 million. In addition, we received proceeds of $270 million from the sale of a partial interest in MVP in April 2021, made $1.7 billion in capital investments, redeemed the total outstanding balance of our $575 million Floating Rate Notes due in 2023, and paid $1.2 billion in dividends during the nine-month period. As a result of this and other activity, our cash and cash equivalents increased by $185 million, from $3.3 billion as of December 31, 2020 to $3.5 billion as of September 30, 2021. We did not issue any debt or make any borrowings under our credit facilities (excluding activity with respect to the committed facilities of our VIEs) during the first nine months of 2021, and we had $8.5 billion in liquidity as of September 30, 2021.

38

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 61.

Third Quarter Results

For the third quarter of 2021, we reported net income attributable to Valero stockholders of $463 million compared to a net loss of $464 million for the third quarter of 2020. The increase of $927 million was primarily due to higher operating income of $1.3 billion, partially offset by higher income tax expense of $402 million.

While our operating income increased by $1.3 billion in the third quarter of 2021 compared to the third quarter of 2020, adjusted operating income also increased by $1.3 billion. Adjusted operating income excludes the adjustments reflected in the table in note (g) on page 60.

The $1.3 billion increase in adjusted operating income was primarily due to the following:

•Refining segment. Refining segment adjusted operating income increased by $1.4 billion primarily due to higher gasoline and distillate (primarily diesel) margins and higher throughput volumes, partially offset by the higher costs of biofuel credits and higher operating expenses (excluding depreciation and amortization expense). This is more fully described on pages 45 and 46.

•Renewable diesel segment. Renewable diesel segment adjusted operating income decreased by $75 million primarily due to higher feedstock costs and lower sales volumes, partially offset by higher renewable diesel prices. This is more fully described on pages 46 and 47.

•Ethanol segment. Ethanol segment adjusted operating income decreased by $32 million primarily due to higher corn prices and higher operating expenses (excluding depreciation and amortization expense), partially offset by higher ethanol and corn related co-product prices. This is more fully described on pages 47 and 48.

First Nine Months Results

For the first nine months of 2021, we reported a net loss attributable to Valero stockholders of $79 million compared to $1.1 billion for the first nine months of 2020. The improvement of $983 million was primarily due to higher operating income of $1.6 billion, partially offset by higher income tax expense of $700 million. The increase in operating income included the favorable effect from a $326 million charge recognized in the first nine months of 2020 for the expected liquidation of LIFO inventory layers, which is described in Note 3 of Condensed Notes to Consolidated Financial Statements.

While our operating income increased by $1.6 billion in the first nine months of 2021 compared to the first nine months of 2020, adjusted operating income increased by $1.4 billion. Adjusted operating income excludes the adjustments reflected in the table in note (g) on page 60.

The $1.4 billion increase in adjusted operating income was primarily due to the following:

•Refining segment. Refining segment adjusted operating income increased by $1.3 billion primarily due to higher margins on gasoline, distillates (primarily diesel), and other products and higher throughput volumes, partially offset by the higher costs of biofuel credits, lower discounts

39

on crude oils, and estimated excess energy costs arising out of Winter Storm Uri. This is more fully described on pages 52 and 53.

•Renewable diesel segment. Renewable diesel segment adjusted operating income increased by $49 million primarily due to higher renewable diesel prices, partially offset by higher feedstock costs, an unfavorable impact from commodity derivative instruments associated with our price risk management activities, lower sales volumes, and higher operating expenses (excluding depreciation and amortization expense). This is more fully described on pages 54 and 55.

•Ethanol segment. Ethanol segment adjusted operating income increased by $100 million primarily due to higher ethanol and corn related co-product prices and higher production volumes, partially offset by higher corn prices and estimated excess energy costs arising out of Winter Storm Uri. This is more fully described on pages 55 and 56.

Outlook

As previously discussed, many uncertainties remain with respect to the COVID-19 pandemic, and while it is difficult to predict the ultimate economic impacts that the pandemic may have on us and how quickly we will continue to recover as the pandemic subsides, we have noted several factors below that have impacted or may impact our results of operations during the fourth quarter of 2021.

•Gasoline and diesel product demand has returned to near pre-pandemic levels and is expected to follow typical seasonal patterns. Jet fuel demand continues to slowly improve but remains below pre-pandemic levels.

•Sour crude oil discounts are expected to continue to improve as OPEC production increases in response to anticipated continued growth in global crude oil demand.

•Renewable diesel margins are expected to moderate somewhat from the levels achieved in the third quarter; however, these effects may be offset by an expected increase in sales volumes following the start up in October 2021 of the expansion of DGD’s renewable diesel plant in Louisiana. The plant’s renewable diesel production capacity was recently expanded by 400 million gallons per year, from 290 million gallons to 690 million gallons per year.

•Ethanol margins are expected to improve due to lower corn prices.

Total Company, Corporate, and Other

The following table includes selected financial data for the total company, corporate, and other for the third quarter of 2021 and 2020. The selected financial data is derived from the Financial Highlights by Segment and Total Company tables on pages 41 and 42, unless otherwise noted.

	Three Months Ended September 30,
	2021		2020		Change
Revenues	$	29,520	$	15,809	$	13,711

Net income attributable to noncontrolling interests	45		85		(40)

Revenues increased by $13.7 billion in the third quarter of 2021 compared to the third quarter of 2020 primarily due to increases in refined petroleum product prices, as well as an increase in the volume of refined petroleum products sold by our refining segment. This increase in revenues was partially offset by an increase in cost of sales of $12.4 billion primarily due to increases in crude oil and other feedstock costs, resulting in a $1.3 billion increase in operating income, from an operating loss of $621 million in the third quarter of 2020 to operating income of $693 million in the third quarter of 2021.

Adjusted operating income also increased by $1.3 billion, from an adjusted operating loss of $553 million in the third quarter of 2020 to adjusted operating income of $760 million in the third quarter of 2021. The components of this increase in adjusted operating income are discussed by segment in the segment analyses that follow.

Income tax expense increased by $402 million in the third quarter of 2021 compared to the third quarter of 2020 primarily as a result of higher income before income tax expense. Our effective tax rate was 11 percent for the third quarter of 2021, which primarily reflects the permanent benefit to our estimated annual effective tax rate from the portion of DGD’s net income that is not taxable to us and a benefit for the settlement of the audits of certain state tax returns in the third quarter of 2021, compared to 47 percent

44

for the third quarter of 2020. The effective tax rate for the third quarter of 2020 was impacted by the U.S. federal tax NOL for 2020, which was carried back to 2015 when the U.S. statutory rate was 35 percent. See Note 9 of Condensed Notes to Consolidated Financial Statements for additional information on these tax matters.

Net income attributable to noncontrolling interests decreased by $40 million in the third quarter of 2021 compared to the third quarter of 2020 primarily due to lower earnings associated with DGD. As described in Note 7 of Condensed Notes to Consolidated Financial Statements, DGD is a joint venture that we consolidate, and DGD’s operations comprise our renewable diesel segment. See the renewable diesel segment analysis below for the reasons for the lower earnings associated with DGD.

Refining Segment Results

The following table includes selected financial and operating data of our refining segment for the third quarter of 2021 and 2020. The selected financial data is derived from the Financial Highlights by Segment and Total Company tables on pages 41 and 42, respectively, unless otherwise noted.

	Three Months Ended September 30,
	2021		2020		Change
Operating income (loss)	$	835	$	(629)	$	1,464

Depreciation and amortization expense	549		538		11
Throughput volumes (thousand barrels per day) (see note (h) on page 60)	2,864		2,526		338

Refining segment operating income increased by $1.5 billion in the third quarter of 2021; however, refining segment adjusted operating income, which excludes the adjustments in the table in note (g) on page 59, increased by $1.4 billion in the third quarter of 2021 compared to the third quarter of 2020. 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 $1.6 billion in the third quarter of 2021 compared to the third quarter of 2020.

Refining segment margin is primarily affected by the prices of the refined petroleum products that we sell and the cost of crude oil and other feedstocks that we process. The table on page 43 reflects market reference prices and differentials that we believe had a material impact on the change in our refining segment margin in the third quarter of 2021 compared to the third quarter of 2020.

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

◦An increase in gasoline margins had a favorable impact of approximately $1.1 billion.

45

◦An increase in distillate (primarily diesel) margins had a favorable impact of approximately $645 million.

◦An increase in throughput volumes of 338,000 barrels per day had a favorable impact of approximately $127 million. As noted in “OVERVIEW AND OUTLOOK—Overview—Business Operations Update” on pages 38 and 39, the impacts of the COVID-19 pandemic have continued to subside so far in 2021. As a result, we have increased production of most of our products at our refineries to align with improvements in demand.

◦An increase in the cost of biofuel credits (primarily RINs in the U.S.) had an unfavorable impact of $475 million. See Note 14 of Condensed Notes to Consolidated Financial Statements for additional information on our government and regulatory compliance programs.

•Refining segment operating expenses (excluding depreciation and amortization expense) increased by $206 million primarily due to higher natural gas and electricity costs of $129 million, an increase in certain employee compensation expenses of $27 million, and higher chemical and catalyst costs of $14 million.

Renewable Diesel Segment Results

The following table includes selected financial and operating data of our renewable diesel segment for the third quarter of 2021 and 2020. The selected financial data is derived from the Financial Highlights by Segment and Total Company tables on pages 41 and 42, respectively, unless otherwise noted.

	Three Months Ended September 30,
	2021		2020		Change
Operating income	$	108	$	184	$	(76)
Adjusted operating income (see note (g) on page 59)	109		184		(75)

Depreciation and amortization expense	11		10		1
Sales volumes (thousand gallons per day) (see note (h) on page 60)	671		870		(199)

Renewable diesel segment operating income decreased by $76 million in the third quarter of 2021, and renewable diesel segment adjusted operating income, which excludes the adjustment in the table in note (g) on page 59, decreased by $75 million in the third quarter of 2021 compared to the third quarter of 2020. This decrease in the adjusted results was primarily due to lower renewable diesel segment margin.

Renewable diesel segment margin decreased by $71 million in the third quarter of 2021 compared to the third quarter of 2020. Renewable diesel segment margin is primarily affected by the price of the renewable diesel that we sell and the cost of the feedstocks that we process. The table on page 44 reflects market reference prices that we believe had a material impact on the change in our renewable diesel segment margin in the third quarter of 2021 compared to the third quarter of 2020.

46

The decrease in renewable diesel segment margin was primarily due to the following:

•An increase in the cost of the feedstocks we process had an unfavorable impact of approximately $139 million.

•A decrease in sales volumes of 199,000 gallons per day primarily attributed to unplanned downtime at the DGD plant due to Hurricane Ida had an unfavorable impact of approximately $52 million. See “OVERVIEW AND OUTLOOK—Overview—Business Operations Update” on pages 38 and 39 for further discussion of the impact of Hurricane Ida on our renewable diesel segment.

•Higher renewable diesel prices had a favorable impact of approximately $131 million.

Ethanol Segment Results

The following table includes selected financial and operating data of our ethanol segment for the third quarter of 2021 and 2020. The selected financial data is derived from the Financial Highlights by Segment and Total Company tables on pages 41 and 42, respectively, unless otherwise noted.

	Three Months Ended September 30,
	2021		2020		Change
Operating income (loss)	$	(44)	$	22	$	(66)
Adjusted operating income (see note (g) on page 59)	4		36		(32)
Ethanol margin (see note (g) on page 58)	$	154	$	165	$	(11)
Operating expenses (excluding depreciation and amortization expense reflected below)	128		105		23
Depreciation and amortization expenses (see note (d) on page 56)	70		54		16
Production volumes (thousand gallons per day) (see note (h) on page 60)	3,625		3,800		(175)

Ethanol segment operating income decreased by $66 million in the third quarter of 2021; however, ethanol segment adjusted operating income, which excludes the adjustments in the table in note (g) on page 59, decreased by $32 million in the third quarter of 2021 compared to the third quarter of 2020. The components of this decrease in the adjusted results, along with the reasons for the changes in those components, are outlined below.

•Ethanol segment margin decreased by $11 million in the third quarter of 2021 compared to the third quarter of 2020.

Ethanol segment margin is primarily affected by prices of the ethanol and corn related co-products that we sell and the cost of corn that we process. The table on page 44 reflects market reference prices that we believe had a material impact on the change in our ethanol segment margin in the third quarter of 2021 compared to the third quarter of 2020.

47

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

◦Higher corn prices had an unfavorable impact of approximately $406 million.

◦Higher ethanol prices had a favorable impact of approximately $318 million.

◦Higher prices on the co-products that we produce, primarily distillers grains, had a favorable impact of approximately $77 million.

•Ethanol segment operating expenses (excluding depreciation and amortization expense) increased by $23 million primarily due to higher natural gas and electricity costs.

Revenues increased by $29.8 billion in the first nine months of 2021 compared to the first nine months of 2020 primarily due to increases in refined petroleum product prices associated with sales made by our refining segment. This increase in revenues was partially offset by an increase in cost of materials and other of $27.0 billion primarily due to increases in crude oil and other feedstock costs, higher operating expenses (excluding depreciation and amortization expense) of $950 million primarily due to estimated excess energy costs of $532 million arising out of Winter Storm Uri, and an increase in general and administrative expenses (excluding depreciation and amortization expense) of $47 million primarily due to an increase in certain employee compensation expenses of $36 million and higher advertising expenses of $11 million. The increase in cost of materials and other was partially offset by the favorable effect from a $326 million LIFO liquidation adjustment in the first nine months of 2020. These changes resulted

51

in a $1.6 billion increase in operating income, from an operating loss of $1.1 billion in the first nine months of 2020 to operating income of $536 million in the first nine months of 2021.

Adjusted operating income increased by $1.4 billion, from an adjusted operating loss of $742 million in the first nine months of 2020 to adjusted operating income of $653 million in the first nine months of 2021. The components of this $1.4 billion increase in adjusted operating income are discussed by segment in the segment analyses that follow.

“Other income, net” increased by $72 million in the first nine months of 2021 compared to the first nine months of 2020 primarily due to the gain of $62 million on the sale of a 24.99 percent membership interest in MVP, partially offset by an asset impairment loss of $24 million resulting from the cancellation of a pipeline extension project by our unconsolidated joint venture, Diamond Pipeline LLC. These matters are more fully described in note (e) on page 56.

“Interest and debt expense, net of capitalized interest” increased by $41 million in the first nine months of 2021 compared to the first nine months of 2020 primarily due to interest expense associated with $4.0 billion aggregate principal amount of debt we issued in public debt offerings in 2020. See Note 5 of Condensed Notes to Consolidated Financial Statements for additional details.

Income tax expense increased by $700 million in the first nine months of 2021 compared to the first nine months of 2020 primarily as a result of a higher income before income tax expense. In addition, the increase in income tax expense was impacted by a $64 million charge, which resulted from certain statutory tax rate changes, as discussed in note (f) on page 57, as well as the effect of a benefit in the first nine months of 2020 of $238 million associated with the U.S. federal tax NOL for 2020, which was carried back to 2015 when the U.S. federal statutory rate was 35 percent. See Note 9 of Condensed Notes to Consolidated Financial Statements for additional information on these tax matters.

Refining Segment Results

The following table includes selected financial and operating data of our refining segment for the first nine months of 2021 and 2020. The selected financial data is derived from the Financial Highlights by Segment and Total Company tables on pages 48 and 49, respectively, unless otherwise noted.

	Nine Months Ended September 30,
	2021		2020		Change
Operating income (loss)	$	592	$	(965)	$	1,557
Adjusted operating income (loss) (see note (g) on page 59)	660		(629)		1,289

Throughput volumes (thousand barrels per day) (see note (h) on page 60)	2,705		2,557		148

Refining segment operating income increased by $1.6 billion in the first nine months of 2021; however, refining segment adjusted operating income, which excludes the adjustments in the table in note (g) on page 59, increased by $1.3 billion in the first nine months of 2021 compared to the first nine months of

52

2020. 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 the first nine months of 2021 compared to the first nine months of 2020.

Refining segment margin is primarily affected by the prices of the refined petroleum products that we sell and the cost of crude oil and other feedstocks that we process. The table on page 50 reflects market reference prices and differentials that we believe had a material impact on the change in our refining segment margin in the first nine months of 2021 compared to the first nine months of 2020.

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

◦An increase in gasoline margins had a favorable impact of approximately $2.8 billion.

◦An increase in distillate (primarily diesel) margins had a favorable impact of approximately $890 million.

◦Higher margins on other products had a favorable impact of approximately $349 million.

◦An increase in throughput volumes of 148,000 barrels per day had a favorable impact of approximately $224 million. As noted in “OVERVIEW AND OUTLOOK—Overview—Business Operations Update” on pages 38 and 39, the impacts of the COVID-19 pandemic have continued to subside so far in 2021. As a result, we have increased production of most of our products at our refineries to align with improvements in demand.

◦An increase in the cost of biofuel credits (primarily RINs in the U.S.) had an unfavorable impact of $1.2 billion. See Note 14 of Condensed Notes to Consolidated Financial Statements for additional information on our government and regulatory compliance programs.

◦Lower discounts on crude oils had an unfavorable impact of approximately $1.2 billion.

•Refining segment operating expenses (excluding depreciation and amortization expense) increased by $818 million primarily due to higher energy costs, which includes the effect of estimated excess energy costs arising out of Winter Storm Uri of $478 million (see note (a) on page 56).

Renewable Diesel Segment Results

The following table includes selected financial and operating data of our renewable diesel segment for the first nine months of 2021 and 2020. The selected financial data is derived from the Financial Highlights by Segment and Total Company tables on pages 48 and 49, respectively, unless otherwise noted.

	Nine Months Ended September 30,
	2021		2020		Change
Operating income	$	559	$	511	$	48
Adjusted operating income (see note (g) on page 59)	560		511		49
Renewable diesel margin (see note (g) on page 58)	$	681	$	607	$	74
Operating expenses (excluding depreciation and amortization expense reflected below)	86		63		23
Depreciation and amortization expense	35		33		2
Sales volumes (thousand gallons per day) (see note (h) on page 60)	819		844		(25)

Renewable diesel segment operating income increased by $48 million in the first nine months of 2021; however, renewable diesel segment adjusted operating income, which excludes the adjustment in the table in note (g) on page 59, increased by $49 million in the first nine months of 2021 compared to the first nine months of 2020. The components of this increase in the adjusted results, along with the reasons for the changes in those components, are outlined below.

•Renewable diesel segment margin increased by $74 million in the first nine months of 2021 compared to the first nine months of 2020. Renewable diesel segment margin is primarily affected by the price of the renewable diesel that we sell and the cost of the feedstocks that we process. The table on page 51 reflects market reference prices that we believe had a material impact on the change in our renewable diesel segment margin in the first nine months of 2021 compared to the first nine months of 2020.

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

◦Higher renewable diesel prices had a favorable impact of approximately $504 million.

◦An increase in the cost of the feedstocks we process had an unfavorable impact of approximately $294 million.

◦Price risk management activities had an unfavorable impact of $79 million. We recognized a hedge loss of $37 million in the first nine months of 2021 compared to a hedge gain of $42 million in the first nine months of 2020.

◦A decrease in sales volumes of 25,000 gallons per day primarily attributed to unplanned downtime at the DGD plant due to Hurricane Ida had an unfavorable impact of approximately $25 million. See “OVERVIEW AND OUTLOOK—Overview—Business Operations Update” on pages 38 and 39 for further discussion of the impact of Hurricane Ida on our renewable diesel segment.

54

•Renewable diesel segment operating expenses (excluding depreciation and amortization expense) increased by $23 million primarily due to higher maintenance expenses of $7 million, an increase in certain employee compensation expenses of $7 million, and higher chemical and catalyst costs of $2 million.

Ethanol Segment Results

The following table includes selected financial and operating data of our ethanol segment for the first nine months of 2021 and 2020. The selected financial data is derived from the Financial Highlights by Segment and Total Company tables on pages 48 and 49, respectively, unless otherwise noted.

	Nine Months Ended September 30,
	2021		2020		Change
Operating loss	$	(1)	$	(84)	$	83
Adjusted operating income (loss) (see note (g) on page 59)	47		(53)		100
Ethanol margin (see note (g) on page 58)	$	513	$	307	$	206
Operating expenses (excluding depreciation and amortization expense reflected below) (see note (a) on page 56)	403		293		110
Depreciation and amortization expense (see note (d) on page 56)	111		97		14
Production volumes (thousand gallons per day) (see note (h) on page 60)	3,797		3,408		389

The ethanol segment operating loss decreased by $83 million in the first nine months of 2021; however, ethanol segment adjusted operating income, which excludes the adjustments in the table in note (g) on page 59, increased by $100 million in the first nine months of 2021 compared to the first nine months of 2020. 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 $206 million in the first nine months of 2021 compared to the first nine months of 2020.

Ethanol segment margin is primarily affected by prices of the ethanol and corn related co-products that we sell and the cost of corn that we process. The table on page 51 reflects market reference prices that we believe had a material impact on the change in our ethanol segment margin in the first nine months of 2021 compared to the first nine months of 2020.

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

◦Higher ethanol prices had a favorable impact of approximately $490 million.

◦Higher prices on the co-products that we produce, primarily distillers grains, had a favorable impact of approximately $152 million.

◦An increase in production volumes of 389,000 gallons per day had a favorable impact of approximately $66 million. As noted in “OVERVIEW AND OUTLOOK—Overview—Business Operations Update” on pages 38 and 39, the impacts of the COVID-19

55

pandemic have continued to subside so far in 2021. As a result, we have increased the aggregate production of ethanol across our plants to align with improvements in demand.

◦Higher corn prices had an unfavorable impact of approximately $489 million.

•Ethanol segment operating expenses (excluding depreciation and amortization expense) increased by $110 million primarily due to higher energy costs, which includes the effect of estimated excess energy costs arising out of Winter Storm Uri of $54 million (see note (a) on page 56).

________________________

The following notes relate to references on pages 37 through 56.

(a)In mid-February 2021, many of our refineries and plants were impacted to varying extents by the severe cold, utility disruptions, and higher energy costs arising out of Winter Storm Uri. The higher energy costs resulted from an increase in the prices of natural gas and electricity that significantly exceeded rates that we consider normal, such as the average rates we incurred the month preceding the storm. As a result, our operating income for the nine months ended September 30, 2021 includes estimated excess energy costs of $579 million.

The above-mentioned pre-tax estimated excess energy charge is reflected in our statement of income line items and attributable to our reportable segments as follows (in millions):

	Refining		Renewable Diesel		Ethanol		Total
Cost of materials and other	$	47	$	—	$	—	$	47
Operating expenses (excluding depreciation and amortization expense)	478		—		54		532
Total estimated excess energy costs	$	525	$	—	$	54	$	579

(b)Cost of materials and other for the three and nine months ended September 30, 2020 includes a charge of $326 million for the impact of an expected liquidation of LIFO inventory layers attributable to our refining segment. Our inventory levels decreased throughout the first nine months of 2020 due to lower demand for our products resulting from the negative economic impacts of the COVID-19 pandemic on our business. Consequently, we expected our inventory levels as of December 31, 2020 would remain below their December 31, 2019 levels.

(c)The market value of our inventories accounted for under the LIFO method fell below their historical cost on an aggregate basis as of March 31, 2020. As a result, we recorded an LCM inventory valuation adjustment of $2.5 billion in March 2020. The market value of our LIFO inventories improved due to the subsequent recovery in market prices, which resulted in a reversal of $2.2 billion in the three months ended June 30, 2020 and the remaining amount in the three months ended September 30, 2020. Of the $313 million benefit recognized in the three months ended September 30, 2020, $296 million and $17 million is attributable to our refining and ethanol segments, respectively. The LCM inventory valuation adjustment for the nine months ended September 30, 2020 reflects a net benefit of $19 million due solely to the foreign currency translation effect of the portion of the LCM inventory valuation adjustments attributable to our international operations.

(d)Depreciation and amortization expense for the three and nine months ended September 30, 2021 and 2020 includes accelerated depreciation of $48 million and $30 million, respectively, related to changes in the estimated useful lives of two of our ethanol plants.

(e)On April 19, 2021, we sold a 24.99 percent membership interest in MVP for $270 million. “Other income, net” for the nine months ended September 30, 2021 includes a gain on the sale of $62 million.

“Other income, net” for the nine months ended September 30, 2021 also includes a $24 million charge representing our portion of the asset impairment loss recognized by Diamond Pipeline LLC, an unconsolidated

56

joint venture with a subsidiary of Plains All American Pipeline, L.P., resulting from the joint venture’s cancellation of its pipeline extension project.

(f)Certain statutory tax rate changes were enacted during the second quarter of 2021 (primarily an increase in the U.K. rate from 19 percent to 25 percent effective in 2023) which resulted in the remeasurement of our deferred tax liabilities. Under U.S. GAAP, we are required to recognize the effect of a change in tax law in the period of enactment. As a result, we recognized income tax expense of $64 million during the nine months ended September 30, 2021, which represents the net increase in our deferred tax liabilities resulting from the change in the tax rates.

(g)We use certain financial measures (as noted below) that are not defined under U.S. 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 our adjusted operating income measures (including for our refining and ethanol segments) are useful to assess our ongoing financial performance because, when reconciled to their most comparable U.S. GAAP measures, they provide improved comparability between periods through the exclusion of certain items that we believe are not indicative of our core operating performance and that may obscure our underlying business results and trends. We believe our refining margin, renewable diesel margin, and ethanol margin, as applicable, are important measures of the relevant segment’s operating and financial performance because, with respect to such segment, 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. 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 our 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 we may define them differently, which diminishes their utility.

Non-GAAP measures are as follows:

◦Refining margin is defined as refining segment operating income (loss) excluding the LIFO liquidation adjustment, the LCM inventory valuation adjustment, operating expenses (excluding depreciation and amortization expense), depreciation and amortization expense, and other operating expenses, as reflected in the table below.

LIQUIDITY AND CAPITAL RESOURCES

Overview

During the nine months ended September 30, 2021, our liquidity was positively impacted by the cash generated by our operations notwithstanding the lingering impacts of the COVID-19 pandemic, excess energy costs arising out of Winter Storm Uri, and the effects of Hurricane Ida, as described in “OVERVIEW AND OUTLOOK—Overview—Business Operations Update.”

We believe that we have sufficient funds from operations and from available capacity under our credit facilities to fund our ongoing operating requirements and other commitments. 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.

Our Liquidity

Our liquidity consisted of the following as of September 30, 2021 (in millions):

Available capacity from our committed facilities (a):
Valero Revolver	$	3,712
Canadian Revolver (b)	114
Accounts receivable sales facility	1,300
Letter of credit facility	50
Total available capacity	5,176
Cash and cash equivalents (c)	3,322
Total liquidity	$	8,498

________________________

(a)Excludes the committed facilities of our VIEs.

(b)The amount for our Canadian Revolver is shown in U.S. dollars. As set forth in the summary of our credit facilities in Note 5 of Condensed Notes to Consolidated Financial Statements, the availability under our Canadian Revolver as of September 30, 2021 in Canadian dollars was C$145 million.

(c)Excludes $176 million of cash and cash equivalents related to our VIEs that is available for use only by our VIEs.

Information about our outstanding borrowings, letters of credit issued, and availability under our credit facilities is reflected in Note 5 of Condensed Notes to Consolidated Financial Statements.

Cash Flows

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

	Nine Months Ended September 30,
	2021		2020
Cash flows provided by (used in):
Operating activities	$	3,405	$	852
Investing activities	(1,412)		(1,852)

Net increase in cash and cash equivalents	$	185	$	1,464

Cash Flows for the Nine Months Ended September 30, 2021

In the first nine months of 2021, we used $3.4 billion of cash generated by our operations to make $1.4 billion of investments in our business, fund $1.9 billion of other financing activities, and increase our available cash on hand by $185 million.

As previously noted, our operations generated $3.4 billion of cash in the first nine months of 2021, driven primarily by a positive change in working capital of $1.6 billion, noncash charges to income of $1.6 billion, and net income of $178 million. Our net income of $178 million reflects the unfavorable impact of increased energy costs at certain of our refineries and ethanol plants due to effects arising out of Winter Storm Uri, as described in “OVERVIEW AND OUTLOOK—Overview—Business Operations Update.” Noncash charges included $1.8 billion of depreciation and amortization expense, partially offset by a $150 million deferred income tax benefit and a $62 million gain on the sale of a partial interest in MVP, as described in Note 7 of Condensed Notes to Consolidated Financial Statements. Details regarding the components of the change in working capital, along with the reasons for the changes in those components, are described in Note 12 of Condensed 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 $1.4 billion consisted of $1.7 billion in capital investments, as defined below, of which $736 million related to self-funded capital investments by DGD, and $59 million was related to capital expenditures of VIEs other than DGD. These activities were partially offset by $270 million received from the sale of a partial interest in MVP, as described in Note 7 of Condensed Notes to Consolidated Financial Statements.

Other financing activities of $1.9 billion consisted primarily of $1.2 billion in dividend payments, $672 million of payments of debt and finance lease obligations (excluding VIEs), and $15 million for the purchase of common stock for treasury in connection with stock-based compensation plans.

Cash Flows for the Nine Months Ended September 30, 2020

In the first nine months of 2020, we used $852 million of cash generated by our operations and $4.5 billion in borrowings to make $1.9 billion of investments in our business, fund $2.1 billion of other

62

financing activities, and increase our available cash on hand by $1.4 billion. The borrowings are described in Note 5 of Condensed Notes to Consolidated Financial Statements.

As previously noted, our operations generated $852 million of cash in the first nine months of 2020, which resulted from noncash charges to income of $1.9 billion, partially offset by an unfavorable change in working capital of $232 million. Noncash charges primarily included $1.8 billion of depreciation and amortization expense and $177 million of deferred income tax expense. The change in working capital was affected primarily by a $1.3 billion use of cash1 resulting from the rapid decline in market prices of refined petroleum products and crude oil as a result of the negative economic effects of the COVID-19 pandemic that impacted our receivables and accounts payable. This use of cash, along with other uses of cash, were partially offset by a $1.6 billion source of cash driven by a reduction in inventory levels on hand. Details regarding the components of the change in working capital, along with the reasons for the changes in those components, are described in Note 12 of Condensed Notes to Consolidated Financial Statements. In addition, see “RESULTS OF OPERATIONS” for an analysis of the significant components of our net loss.

Our investing activities of $1.9 billion consisted of $1.9 billion in capital investments, as defined below, of which $329 million related to self-funded capital investments by DGD, and $196 million was related to capital expenditures of VIEs other than DGD.

Other financing activities of $2.1 billion consisted primarily of $1.2 billion in dividend payments, $461 million of payments of debt and finance lease obligations (excluding VIEs), $208 million to pay distributions to noncontrolling interests, and $147 million for the purchase of common stock for treasury.

Capital Investments

Our capital investments include capital expenditures, deferred turnaround and catalyst cost expenditures, and investments in unconsolidated joint ventures. Capital investments attributable to Valero, which is a non-GAAP financial measure, reflects our net share of capital investments and is defined as all capital expenditures, deferred turnaround and catalyst cost expenditures, and investments in unconsolidated joint ventures presented in our consolidated statements of cash flows, excluding the portion of DGD’s capital investments attributable to our joint venture partner and all of the capital expenditures of other VIEs.

We are a 50/50 joint venture partner in DGD and consolidate DGD’s financial statements; 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. DGD’s partners 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 partner, only 50 percent of DGD’s capital investments should be attributed to our net share of capital investments. We also exclude the capital expenditures of our other consolidated VIEs because we do not operate those VIEs. 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, its most comparable U.S. GAAP measure, nor should it be considered in isolation or as a substitute for an analysis of our cash flows as reported under U.S. GAAP. In addition, this non-GAAP

1 Represents the net cash flow change in “receivables, net” of $3.6 billion and accounts payable of $4.9 billion during the nine months ended September 30, 2020, as described in Note 12 of Condensed Notes to Consolidated Financial Statements.

63

measure may not be comparable to similarly titled measures used by other companies because we may define it differently, which may diminish its utility.

	Nine Months Ended September 30,
	2021		2020
Reconciliation of capital investments to capital investments attributable to Valero
Capital expenditures (excluding VIEs)	$	368	$	775
Capital expenditures of VIEs:
DGD	730		311
Other VIEs	59		196
Deferred turnaround and catalyst cost expenditures (excluding VIEs)	544		529
Deferred turnaround and catalyst cost expenditures of DGD	6		18
Investments in unconsolidated joint ventures	8		39
Capital investments	1,715		1,868
Adjustments:
DGD’s capital investments attributable to our joint venture partner	(368)		(165)
Capital expenditures of other VIEs	(59)		(196)
Capital investments attributable to Valero	$	1,288	$	1,507

As previously disclosed in our annual report on Form 10-K for the year ended December 31, 2020, we expect to incur $2.0 billion for capital investments attributable to Valero during 2021; however, we continuously evaluate our capital budget and make changes as conditions warrant. Approximately 60 percent of the expected capital investments attributable to Valero are for sustaining the business and 40 percent are for growth strategies, of which over 60 percent is allocated to expanding the renewable diesel business.

We have publicly announced GHG emissions reduction/offset targets for 2025 and 2035. We believe that our expected allocation of growth capital into lower-carbon projects is consistent with such targets. Certain of these lower-carbon projects are already in execution and the associated capital investments are included in our expected capital investments for 2021 discussed above. Our capital investments in future years to achieve these targets are expected to include investments associated with certain lower-carbon projects currently at various stages of progress, evaluation, or approval.

Other Matters Impacting Liquidity and Capital Resources

Stock Purchase Program

As of September 30, 2021, we had $1.4 billion available for purchase under our stock purchase program, which has no expiration date. We have not purchased any shares of our common stock under our stock purchase program since mid-March 2020, and we will evaluate the timing of repurchases when appropriate. We have no obligation to make purchases under this program.

Pension Plan Funding

As previously disclosed in our annual report on Form 10-K for the year ended December 31, 2020, we plan to contribute approximately $128 million to our pension plans and $22 million to our other postretirement benefit plans during 2021. As described in Note 8 of Condensed Notes to Consolidated

64

Financial Statements, during the nine months ended September 30, 2021 we contributed $121 million to our pension plans and $12 million to our other postretirement benefit plans.

Environmental Matters

Our operations are subject to extensive environmental regulations by governmental authorities relating to the discharge of materials into the environment, waste management, pollution prevention measures, GHG emissions, and characteristics and composition of gasolines and distillates. Because environmental laws and regulations are becoming more complex and stringent and new environmental laws and regulations are continuously being enacted or proposed, the level of future expenditures required for environmental matters could increase in the future. In addition, any major upgrades in any of our refineries or plants could require material additional expenditures to comply with environmental laws and regulations. See Note 14 of Condensed Notes to Consolidated Financial Statements for additional information on our government and regulatory compliance program and related costs.

Tax Matters

We deferred approximately $250 million of value-added and motor fuel tax payments that were due in 2020 as permitted by various taxing authorities to help companies address the negative impacts of the COVID-19 pandemic. Of this amount, approximately 90 percent will be paid in 2021 and 10 percent in 2022. During the first nine months of 2021, we paid approximately $125 million of these tax payments.

Cash Held by Our International Subsidiaries

As of September 30, 2021, $3.0 billion of our cash and cash equivalents was held by our international subsidiaries. Cash held by our international subsidiaries can be repatriated to us without any U.S. federal income tax consequences, but certain other taxes may apply, including, but not limited to, withholding taxes imposed by certain international jurisdictions and U.S. state income taxes. Therefore, there is a cost to repatriate cash held by certain of our international subsidiaries to us, but we believe that such amount is not material to our financial position or liquidity.

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 the COVID-19 pandemic and volatility in the global 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.

Contractual Obligations

As of September 30, 2021, our contractual obligations included debt, finance lease obligations, operating lease obligations, purchase obligations, and other long-term liabilities. In the ordinary course of business, we had debt-related activities during the nine months ended September 30, 2021, as described in Note 5 of Condensed Notes to Consolidated Financial Statements. There were no material changes outside the ordinary course of business with respect to our contractual obligations during the nine months ended September 30, 2021.

Our 4.0 percent Gulf Opportunity Zone Revenue Bonds Series 2010 (GO Zone Bonds), which total $300 million, are due December 1, 2040, but are subject to mandatory tender on June 1, 2022, (the Mandatory Tender Date), at a price equal to par plus accrued and unpaid interest up to, but excluding, the Mandatory Tender Date. However, we have the option to effectuate a remarketing of these bonds, and we

65

currently expect to remarket them effective on or soon after the Mandatory Tender Date or otherwise refinance them, but we cannot provide any assurance that we will be able to do so. The GO Zone Bonds are reflected in current portion of debt and finance lease obligations as of September 30, 2021.

Central Mexico Terminals’ outstanding borrowings under the IEnova Revolver are also reflected in current portion of debt and finance lease obligations as of September 30, 2021 as IEnova can demand repayment from Central Mexico Terminals, but we do not expect IEnova to demand repayment during the next 12 months. Central Mexico Terminals is owned by IEnova. See Note 7 of Condensed Notes to Consolidated Financial Statements for a description of and accounting for Central Mexico Terminals.

CRITICAL ACCOUNTING ESTIMATES

The preparation of financial statements in conformity with U.S. GAAP requires us to make estimates and assumptions that affect the amounts reported in our financial statements and accompanying notes. Actual results could differ from those estimates. As of September 30, 2021, there were no significant changes to our critical accounting estimates since the date our annual report on Form 10-K for the year ended December 31, 2020 was filed.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

COMMODITY PRICE RISK

We are exposed to market risks related to the volatility in the price of feedstocks (primarily crude oil and corn), the products we produce (primarily refined petroleum products), 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 in order to lock-in such forecasted transactions 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 has been approved by our board of directors.

As of September 30, 2021 and December 31, 2020, 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 14 of Condensed Notes to Consolidated Financial Statements for notional volumes associated with these derivative contracts as of September 30, 2021.

66

COMPLIANCE PROGRAM PRICE RISK

We are exposed to market risk related to the volatility in the price of credits needed to comply with various governmental and regulatory environmental compliance programs. To manage this risk, we enter into contracts to purchase these credits as appropriate. As of September 30, 2021 and December 31, 2020, 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 14 of Condensed Notes to Consolidated Financial Statements for a discussion about these compliance programs.

INTEREST RATE RISK

The following table provides information about our debt instruments (dollars in millions), the fair values of which are sensitive to changes in interest rates. Principal cash flows and related weighted-average interest rates by expected maturity dates are presented. See Note 5 of Condensed Notes to Consolidated Financial Statements for additional information related to our debt.

(b)As of September 30, 2021, our floating rate debt included $100 million associated with borrowings under the DGD Revolver, which is only available to the operations of DGD. DGD’s lender does not have recourse against us. As of September 30, 2021 and December 31, 2020, our floating rate debt included $627 million and $598 million, respectively, associated with borrowings under the IEnova Revolver for the construction of terminals in Mexico by Central Mexico Terminals. The IEnova Revolver is only available to the operations of Central Mexico Terminals. IEnova does not have recourse against us.

(c)See “MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS—LIQUIDITY AND CAPITAL RESOURCES—Other Matters Impacting Liquidity and Capital Resources—Contractual Obligations” for a discussion of the Mandatory Tender Date and maturity date of our GO Zone Bonds.

(d)As of September 30, 2021 and December 31, 2020, we had an interest rate swap associated with $26 million and $31 million, respectively, of our floating rate debt resulting in an effective interest rate of 3.85 percent as of each of those reporting dates. The fair value of the swap was immaterial for all periods presented.

67

FOREIGN CURRENCY RISK

We are exposed to exchange rate fluctuations on transactions related to our international 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 use foreign currency contracts. The following table provides information about our foreign currency contracts (dollars in millions) that, as of the dates set forth below, mature in 2021, the fair values of which are sensitive to changes in foreign currency exchange rates. Currency abbreviations presented below are as follows: U.S. dollars (USD), Canadian dollars (CAD), and pounds sterling (GBP).

	Receive USD/ Pay CAD		Receive USD/ Pay GBP		Receive CAD/ Pay USD

ITEM 4.     CONTROLS AND PROCEDURES

(a)Evaluation of disclosure controls and procedures.

Our management has evaluated, with the participation of our principal executive officer and principal financial officer, the effectiveness of our disclosure controls and procedures (as defined in Rule 13a-15(e) under the Securities Exchange Act of 1934) as of the end of the period covered by this report, and has concluded that our disclosure controls and procedures were effective as of September 30, 2021.

(b)Changes in internal control over financial reporting.

There has been no change in our internal control over financial reporting that occurred during our last fiscal quarter that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

PART II – OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

The information below describes new proceedings or material developments in proceedings that we previously reported in our annual report on Form 10-K for the year ended December 31, 2020 or in our quarterly reports on Form 10-Q for the quarterly periods ended March 31, 2021 and June 30, 2021.

Environmental Enforcement Matters

While it is not possible to predict the outcome of the following environmental proceeding, if it was decided against us, we believe that there would be no material effect on our financial position, results of operations, or liquidity. We are reporting this proceeding to comply with U.S. SEC regulations, which require us to disclose certain information about proceedings arising under federal, state, or local provisions regulating the discharge of materials into the environment or protecting the environment if we reasonably believe that such proceedings may result in monetary sanctions of $300,000 or more.

Texas Commission on Environmental Quality (TCEQ) (Bill Greehey East Refinery). On August 27, 2021, our Bill Greehey East Refinery received a Notice of Enforcement (NOE) from the TCEQ resulting from violations of its Title V permit. We are working with the TCEQ to resolve the NOE, which we reasonably believe may result in penalties in excess of $300,000.

ITEM 1A. RISK FACTORS

There have been no material changes from the risk factors disclosed in our annual report on Form 10-K for the year December 31, 2020. However, to the extent the COVID-19 pandemic adversely affects our business, financial condition, results of operation, and liquidity, it may also have the effect of heightening many of the other risks described in such risk factors.

Basis of Presentation

General

The terms “Valero,” “we,” “our,” and “us,” as used in this report, may refer to Valero Energy Corporation, one or more of its consolidated subsidiaries, or all of them taken as a whole. The term “DGD,” as used in this report, may refer to Diamond Green Diesel Holdings LLC, its wholly owned consolidated subsidiary — Diamond Green Diesel LLC, or both of them taken as a whole.

These unaudited financial statements have been prepared in accordance with United States (U.S.) generally accepted accounting principles (GAAP) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X of the Securities Exchange Act of 1934. Accordingly, they do not include all of the information and notes required by U.S. GAAP for complete financial statements. In the opinion of management, all adjustments considered necessary for a fair presentation of our results for the nine months ended September 30, 2021 have been included. All such adjustments are of a normal recurring nature unless disclosed otherwise. Operating results for the nine months ended September 30, 2021 are not necessarily indicative of the results that may be expected for the year ending December 31, 2021. The financial statements presented herein should be read in conjunction with the financial statements included in our annual report on Form 10-K for the year ended December 31, 2020.

The balance sheet as of December 31, 2020 has been derived from our audited financial statements as of that date. For further information, refer to our financial statements and notes thereto included in our annual report on Form 10-K for the year ended December 31, 2020.

Significant Accounting Policies

Use of Estimates

The preparation of financial statements in conformity with U.S. GAAP requires us to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates. On an ongoing basis, we review our estimates based on currently available information. Changes in facts and circumstances may result in revised estimates.

Adoption of Accounting Pronouncement

The following Financial Accounting Standards Board (FASB) Accounting Standards Update (ASU) was issued and adopted by us on January 7, 2021. Our adoption of this ASU did not have a material impact on our financial statements or related disclosures.

UNCERTAINTIES

2.    UNCERTAINTIES

At the onset of the COVID-19 pandemic in March 2020, governmental authorities around the world imposed restrictions, such as stay-at-home orders and other social distancing measures, to slow the spread of COVID-19. These measures resulted in significant economic disruption globally as reduced economic

activity negatively impacted many businesses, including our business. We experienced a decline in the demand for most of the transportation fuels that we produce and sell, and thus also a decline in the market prices of those products, due to a decrease in the level of individual movement and travel resulting from the restrictions and general public health concerns. Some governmental authorities began lifting restrictions in the latter part of 2020 and this has continued throughout the first nine months of 2021. These actions have contributed to increasing levels of individual movement and travel and a resulting increase in the demand for and market prices of our products. However, some governmental authorities continue to impose some level of restrictions due in part to new outbreaks, including those related to new variants of the COVID-19 virus.

The distribution of vaccines beginning in late 2020 has helped decrease rates of infection and contributed to the lifting of many restrictions. The ongoing distribution of vaccines may result in the continued lifting of restrictions globally and may be seen as a key factor contributing to the ongoing restoration of public confidence, and thus also to stimulating and increasing global economic activity. However, the risk remains that vaccines may not be distributed widely on a timely basis, they may not be as effective against new variants of the virus, the distribution of some or all of the vaccines may be paused or withdrawn due to concerns with potential side effects, and/or the level of individuals’ willingness to receive a vaccine may not be as strong or as timely as needed. Additionally, many governmental authorities have recently announced requirements and mandates, including steep fines for non-compliance, on employers concerning workforce vaccination and testing. Many large companies across the globe, independent of such government regulations, have also begun implementing vaccine requirements and mandates for their workforce, or as a prerequisite to providing customers certain goods and services in person. These requirements and mandates have evoked mixed reactions and have created additional challenges and costs, both administratively and operationally, for employers and employees. Developments with respect to such requirements and mandates are evolving at a rapid pace and the ultimate impact thereof remains uncertain.

Based on these and other circumstances that cannot be predicted, the broader implications of the pandemic on our results of operations and financial position remain uncertain and may continue to be significant. We believe we have proactively responded to many of the known impacts of the pandemic on our business to the extent practicable and we strive to continue to do so, but there can be no assurance that these or other measures will be fully effective.

Inventory Disclosure [Abstract]

INVENTORIES

3.    INVENTORIES

Inventories consisted of the following (in millions):

	September 30, 2021		December 31, 2020
Refinery feedstocks	$	1,646	$	1,979
Refined petroleum products and blendstocks	3,944		3,425
Renewable diesel feedstocks and products	113		50
Ethanol feedstocks and products	233		297
Materials and supplies	291		287
Inventories	$	6,227	$	6,038

We compare the market value of inventories to their cost on an aggregate basis, excluding materials and supplies. In determining the market value of our inventories, we assume that feedstocks are converted into refined products, which requires us to make estimates regarding the refined products expected to be produced from those feedstocks and the conversion costs required to convert those feedstocks into refined products. We also estimate the usual and customary transportation costs required to move the inventory from our plants to the appropriate points of sale. We then apply an estimated selling price to our inventories. If the aggregate market value is less than the aggregate cost, we recognize a loss for the difference in our statements of income. To the extent the aggregate market value of our last-in, first-out (LIFO) inventories subsequently increases, we recognize an increase to the value of our inventories (not to exceed cost) and a gain in our statements of income.

The market value of our LIFO inventories fell below their LIFO inventory carrying amounts as of March 31, 2020, and as a result, we recorded an LCM inventory valuation reserve of $2.5 billion in order to state our inventories at market. As of September 30, 2020, we reevaluated our inventories and determined that our cost was lower than market. As a result, our LCM inventory valuation reserve was fully reversed as of September 30, 2020. The change in our LCM inventory valuation reserve resulted in a net benefit of $313 million during the three months ended September 30, 2020. The net benefit of $19 million for the nine months ended September 30, 2020 was due to the foreign currency translation effect of the portion of the LCM inventory valuation adjustment attributable to our international operations. As of September 30, 2021 and December 31, 2020, the replacement cost (market value) of LIFO inventories exceeded their LIFO carrying amounts by $5.2 billion and $1.3 billion, respectively.

During the three and nine months ended September 30, 2020, we recognized the impact of an expected liquidation of LIFO inventory layers that increased cost of materials and other by $326 million. Our LIFO inventory levels decreased throughout the first nine months of 2020 due to lower production resulting from lower demand for our products caused by the negative economic impacts of the COVID-19 pandemic on our business. Consequently, we expected our LIFO inventory levels as of December 31, 2020 would remain below their December 31, 2019 levels.

Our non-LIFO inventories accounted for $1.2 billion and $918 million of our total inventories as of September 30, 2021 and December 31, 2020, respectively.

PROPERTY, PLANT, AND EQUIPMENT

4.    PROPERTY, PLANT, AND EQUIPMENT

In September 2021 and 2020, we reduced the estimated useful lives of our ethanol plants in Jefferson, Wisconsin and Riga, Michigan, respectively, which reduced their net book values to estimated salvage value. The additional depreciation expense for the three and nine months ended September 30, 2021 and 2020 of $48 million and $30 million, respectively, resulting from these changes did not have a material impact on our results of operations nor was there a material impact to our financial position.

The Jefferson plant was temporarily idled in 2020 at the onset of the COVID-19 pandemic in response to the decreased demand for ethanol resulting from the effects of the pandemic on our business, and we had previously evaluated this plant for potential impairment assuming that operations would resume. However, we completed an evaluation of the plant during the third quarter of 2021 and concluded that it

was no longer a strategic asset for our ethanol business. As a result, the plant’s operations have permanently ceased.

The Riga plant was temporarily idled in 2019 due to corn quality issues with the local third-party corn feedstock supply. Although we expected operations to resume after an improved corn harvest, we completed an evaluation of this plant during the third quarter of 2020 and concluded that it was no longer a strategic asset for our ethanol business. The plant’s operations permanently ceased at that time.

DGD Revolver

In March 2021, DGD (as described in Note 7) entered into a $400 million unsecured revolving credit facility (the DGD Revolver) that matures in March 2024. DGD has the option to increase the aggregate commitments under the DGD Revolver to $550 million, subject to certain restrictions. Initially, the DGD Revolver also provided for the issuance of letters of credit of up to $10 million. In September 2021, the DGD Revolver was amended to increase the letter of credit facility from $10 million to $50 million and to limit DGD’s indebtedness arising under other letters of credit that DGD may obtain up to $25 million at

any one time outstanding. This restriction does not impact Valero’s other letter of credit facilities. The DGD Revolver is only available to the operations of DGD. DGD’s lender does not have recourse against us.

Outstanding borrowings under the DGD Revolver generally bear interest, at DGD’s option, at either (i) an alternate base rate plus the applicable margin or (ii) an adjusted LIBOR rate for the applicable interest period in effect from time to time plus the applicable margin. The DGD Revolver also requires payments for customary fees, including unused commitment fees, letter of credit fees, and administrative agent fees. As of September 30, 2021, the variable interest rate on the DGD Revolver was 1.840 percent.

IEnova Revolver

In May 2021, the borrowing capacity under the IEnova Revolver was increased from $660 million to $743 million. As of September 30, 2021 and December 31, 2020, the variable weighted-average interest rate on the IEnova Revolver was 3.497 percent and 3.870 percent, respectively. The IEnova Revolver is available only to the operations of Central Mexico Terminals (as described in Note 7). IEnova does not have recourse against us.

Consolidated VIEs

We consolidate a VIE when we have a variable interest in an entity for which we are the primary beneficiary. As of September 30, 2021, our significant consolidated VIEs included:

•DGD, a joint venture with a subsidiary of Darling Ingredients Inc., which owns and operates a plant that processes rendered and recycled materials, including animal fats, used cooking oils, and other vegetable oils, into renewable diesel; and

•Central Mexico Terminals, which is a collective group of three subsidiaries of Infraestructura Energetica Nova, S.A.B. de C.V. (IEnova), a Mexican company and subsidiary of Sempra Energy, a U.S. public company. We have terminaling agreements with Central Mexico Terminals that represent variable interests. We do not have an ownership interest in Central Mexico Terminals.

The assets of our VIEs can only be used to settle their own obligations and the creditors of our VIEs have no recourse to our other assets. We do not provide financial guarantees to our VIEs. Although we have provided credit facilities to some of our VIEs in support of their construction or acquisition activities, these transactions are eliminated in consolidation. Our financial position, results of operations, and cash flows are impacted by the performance of our consolidated VIEs, net of intercompany eliminations, to the extent of our ownership interest in each VIE.

The following tables present summarized balance sheet information for the significant assets and liabilities of our consolidated VIEs, which are included in our balance sheets (in millions):

Non-Consolidated VIEs

We hold variable interests in VIEs that have not been consolidated because we are not considered the primary beneficiary. These non-consolidated VIEs are not material to our financial position or results of operations and are accounted for as equity investments.

On April 19, 2021, we sold a 24.99 percent membership interest in MVP, an unconsolidated joint venture with a subsidiary of Magellan Midstream Partners, L.P. (Magellan), for $270 million that resulted in a gain of $62 million, which is included in “other income, net.” MVP owns and operates a marine terminal located adjacent to the Houston Ship Channel in Pasadena, Texas. We retained a 25.01 percent membership interest in MVP.

INCOME TAXES

9.    INCOME TAXES

Our income tax expense for the three and nine months ended September 30, 2021 included a permanent income tax benefit to our estimated annual effective tax rate from DGD’s share of pre-tax income that is not taxable to us and a benefit for the settlement of the audits of certain state tax returns for 2004 through 2006. In addition, income tax expense for the nine months ended September 30, 2021 included a $64 million charge, which resulted from certain statutory income tax rate changes (primarily an increase in the United Kingdom (U.K.) rate from 19 percent to 25 percent effective in 2023) that were enacted during the three months ended June 30, 2021. The variation in the customary relationship of our effective tax rate to the U.S. federal statutory rate for the three and nine months ended September 30, 2021 was primarily due to these components of our tax expense.

On March 27, 2020, the Coronavirus Aid, Relief and Economic Security (CARES) Act was enacted, which resulted in significant changes to the U.S. Internal Revenue Code of 1986, as amended. Our income tax benefit for the three and nine months ended September 30, 2020, therefore, included a tax benefit of $121 million and $238 million, respectively, attributable to the carryback of our 2020 tax net operating loss (NOL) to our 2015 income tax year when we paid U.S. federal income taxes at a 35 percent tax rate. The variation in the customary relationship of our effective tax rate to the U.S. federal statutory rate for the three and nine months ended September 30, 2020 was primarily due to this income tax benefit.

Revenue from Contracts with Customers

Disaggregation of Revenue

Revenue is presented in the table below under “Segment Information” disaggregated by product because this is the level of disaggregation that management has determined to be beneficial to users of our financial statements.

Contract Balances

Contract balances were as follows (in millions):

	September 30, 2021		December 31, 2020
Receivables from contracts with customers, included in receivables, net	$	5,597	$	3,642
Contract liabilities, included in accrued expenses	67		55

During the nine months ended September 30, 2021 and 2020, we recognized as revenue $44 million and $53 million that was included in contract liabilities as of December 31, 2020 and 2019, respectively. Revenue recognized during the three months ended September 30, 2021 and 2020 related to contract liabilities was not material.

Remaining Performance Obligations

We have spot and term contracts with customers, the majority of which are spot contracts with no remaining performance obligations. We do not disclose remaining performance obligations for contracts that have terms of one year or less. The transaction price for our remaining term contracts includes a fixed component and variable consideration (i.e., a commodity price), both of which are allocated entirely to a wholly unsatisfied promise to transfer a distinct good that forms part of a single performance obligation. The fixed component is not material and the variable consideration is highly uncertain. Therefore, as of September 30, 2021, we have not disclosed the aggregate amount of the transaction price allocated to our remaining performance obligations.

Segment Information

We have three reportable segments — refining, renewable diesel, and ethanol. Each segment is a strategic business unit that offers different products and services by employing unique technologies and marketing strategies and whose operations and operating performance are managed and evaluated separately. Operating performance is measured based on the operating income generated by the segment, which includes revenues and expenses that are directly attributable to the management of the respective segment. Intersegment sales are generally derived from transactions made at prevailing market rates. The following is a description of each segment’s business operations.

•The refining segment includes the operations of our petroleum refineries, the associated marketing activities, and logistics assets that support our refining operations. The principal products manufactured by our refineries and sold by this segment include gasolines and blendstocks, distillates, and other products.

•The renewable diesel segment represents the operations of DGD, our consolidated joint venture as discussed in Note 7. The principal product manufactured by DGD and sold by this segment is renewable diesel. This segment sells some renewable diesel to the refining segment, which is then sold to that segment’s customers.

•The ethanol segment includes the operations of our ethanol plants, the associated marketing activities, and logistics assets that support our ethanol operations. The principal products manufactured by our ethanol plants are ethanol and distillers grains. This segment sells some ethanol to the refining segment for blending into gasoline, which is sold to that segment’s customers as a finished gasoline product.

Operations that are not included in any of the reportable segments are included in the corporate category.

The following tables reflect information about our operating income (loss) by reportable segment (in millions):

Supplemental Cash Flow Information [Abstract]

SUPPLEMENTAL CASH FLOW INFORMATION

12.    SUPPLEMENTAL CASH FLOW INFORMATION

In order to determine net cash provided by operating activities, net income (loss) is adjusted by, among other things, changes in current assets and current liabilities as follows (in millions):

	Nine Months Ended September 30,
	2021		2020
Decrease (increase) in current assets:
Receivables, net	$	(2,643)	$	3,229
Inventories	(232)		1,577
Prepaid expenses and other	28		70
Increase (decrease) in current liabilities:
Accounts payable	3,624		(4,893)
Accrued expenses	538		17
Taxes other than income taxes payable	200		(24)
Income taxes payable	115		(208)
Changes in current assets and current liabilities	$	1,630	$	(232)

Changes in current assets and current liabilities for the nine months ended September 30, 2021 were primarily due to the following:

•the increase in receivables was primarily due to an increase in refined petroleum product prices in September 2021 compared to December 2020 combined with an increase in refined petroleum product sales volumes, partially offset by a decrease in income taxes receivable associated with the receipt of a $962 million refund related to our U.S federal income tax return for 2020;

•the increase in accounts payable was primarily due to an increase in crude oil and other feedstock prices in September 2021 compared to December 2020 combined with an increase in crude oil and other feedstock volumes purchased; and

•the increase in accrued expenses was primarily due to an increase in our environmental credit obligations under fixed-price contracts that resulted from higher prices for Renewable Identification Numbers (RINs) in September 2021 compared to December 2020.

Changes in current assets and current liabilities for the nine months ended September 30, 2020 were primarily due to the following:

•the decrease in receivables was due to (i) a decrease of $3.6 billion as a result of a decrease in sales volumes combined with a decrease in refined petroleum product prices in September 2020 compared to December 2019 and (ii) the collection of $449 million for a blender’s tax credit receivable attributable to volumes blended during 2019 and 2018, partially offset by an increase in income taxes receivable of $770 million primarily due to the recognition of a current income tax benefit;

•the decrease in inventories was primarily due to lower inventory levels in September 2020 compared to December 2019; and

•the decrease in accounts payable was due to a decrease in crude oil and other feedstock volumes purchased combined with a decrease in crude oil and other feedstock prices in September 2020 compared to December 2019.

Recurring Fair Value Measurements

The following tables present information (in millions) about our assets and liabilities recognized at their fair values in our balance sheets categorized according to the fair value hierarchy of the inputs utilized by us to determine the fair values as of September 30, 2021 and December 31, 2020.

We have elected to offset the fair value amounts recognized for multiple similar derivative contracts executed with the same counterparty, including any related cash collateral assets or obligations as shown below; however, fair value amounts by hierarchy level are presented in the following tables on a gross basis. We have no derivative contracts that are subject to master netting arrangements that are reflected gross on the balance sheet.

A description of our assets and liabilities recognized at fair value along with the valuation methods and inputs we used to develop their fair value measurements are as follows:

•Commodity derivative contracts consist primarily of exchange-traded futures, which are used to reduce the impact of price volatility on our results of operations and cash flows as discussed in Note 14. These contracts are measured at fair value using a market approach based on quoted prices from the commodity exchange and are categorized in Level 1 of the fair value hierarchy.

•Physical purchase contracts represent the fair value of fixed-price corn purchase contracts. The fair values of these purchase contracts are measured using a market approach based on quoted prices from the commodity exchange or an independent pricing service and are categorized in Level 2 of the fair value hierarchy.

•Foreign currency contracts consist of foreign currency exchange and purchase contracts and foreign currency swap agreements related to our international operations to manage our exposure to exchange rate fluctuations on transactions denominated in currencies other than the local (functional) currencies of our operations. These contracts are valued based on quoted foreign currency exchange rates and are categorized in Level 1 of the fair value hierarchy.

•Investments of certain benefit plans consist of investment securities held by trusts for the purpose of satisfying a portion of our obligations under certain U.S. nonqualified benefit plans. The plan assets categorized in Level 1 of the fair value hierarchy are measured at fair value using a market approach based on quoted prices from national securities exchanges. The plan assets categorized

in Level 3 of the fair value hierarchy represent insurance contracts, the fair value of which is provided by the insurer.

•Environmental credit obligations represent our liability for the purchase of (i) biofuel credits (primarily RINs in the U.S.) needed to satisfy our blending obligation under the U.S. federal Renewable Fuel Standard (RFS) and similar biofuel blending programs, such as the U.K. Renewable Transport Fuel Obligation, (collectively, the biofuels programs); and (ii) emission credits needed under various other environmental emissions programs (collectively, the other environmental emissions programs). To the degree we are unable to blend biofuels (such as ethanol and biodiesel, including renewable diesel) at percentages required under the biofuel programs, we must purchase biofuel credits to comply with these programs. Under the other environmental emissions programs, we also must purchase emission credits to comply with these programs. These programs are described in Note 14 under “Risk Management Activities by Type of Risk—Environmental Compliance Program Price Risk.” The liability for environmental credits is based on our deficit for such credits as of the balance sheet date, if any, after considering any credits acquired or under contract, and is equal to the product of the credits deficit and the market price of these credits as of the balance sheet date. The environmental credit obligations are categorized in Level 2 of the fair value hierarchy and are measured at fair value using a market approach based on quoted prices from an independent pricing service.

Nonrecurring Fair Value Measurements

There were no assets or liabilities that were measured at fair value on a nonrecurring basis as of September 30, 2021 and December 31, 2020.

Other Financial Instruments

Financial instruments that we recognize in our balance sheets at their carrying amounts are shown in the following table along with their associated fair values (in millions):

Derivative Instruments and Hedging Activities Disclosure [Abstract]

PRICE RISK MANAGEMENT ACTIVITIES

14.    PRICE RISK MANAGEMENT ACTIVITIES

General

We are exposed to market risks primarily related to the volatility in the price of commodities, foreign currency exchange rates, and the price of credits needed to comply with various government and regulatory programs. We enter into derivative instruments to manage some of these risks, including derivative instruments related to the various commodities we purchase or produce, and foreign currency exchange and purchase contracts, as described below under “Risk Management Activities by Type of Risk.” These derivative instruments are recorded as either assets or liabilities measured at their fair values (see Note 13), as summarized below under “Fair Values of Derivative Instruments.” The effect of these derivative instruments on our income and other comprehensive income (loss) is summarized below under “Effect of Derivative Instruments on Income and Other Comprehensive Income (Loss).”

Risk Management Activities by Type of Risk

Commodity Price Risk

We are exposed to market risks related to the volatility in the price of feedstocks (primarily crude oil and corn), the products we produce (primarily refined petroleum products), 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, such as futures and options. 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 has been approved by our board of directors.

We primarily use commodity derivative instruments as cash flow hedges and economic hedges. Our objectives for entering into each type of hedge is described below.

•Cash flow hedges – The objective of our cash flow hedges is to lock in the price of forecasted purchases and/or product sales at existing market prices that we deem favorable.

•Economic hedges – Our objectives for holding economic hedges are to (i) manage price volatility in certain feedstock and product inventories and (ii) lock in the price of forecasted purchases and/or product sales at existing market prices that we deem favorable.

As of September 30, 2021, we had the following outstanding commodity derivative instruments that were used as cash flow hedges and economic hedges, as well as commodity derivative instruments related to the physical purchase of corn at a fixed price. The information presents the notional volume of outstanding contracts by type of instrument and year of maturity (volumes in thousands of barrels, except corn contracts that are presented in thousands of bushels).

	Notional Contract Volumes by Year of Maturity
	2021	2022
Derivatives designated as cash flow hedges:
Refined petroleum products:
Futures – long	1,162	501
Futures – short	3,400	501
Derivatives designated as economic hedges:
Crude oil and refined petroleum products:
Futures – long	63,320	1,354
Futures – short	61,498	1,173
Corn:
Futures – long	85,540	1,615
Futures – short	103,295	6,395
Physical contracts – long	16,441	4,792

Foreign Currency Risk

We are exposed to exchange rate fluctuations on transactions related to our international operations that are denominated in currencies other than the local (functional) currencies of our operations. To manage our exposure to these exchange rate fluctuations, we use foreign currency contracts. These contracts are not designated as hedging instruments for accounting purposes and therefore are classified as economic hedges. As of September 30, 2021, we had foreign currency contracts to purchase $463 million of U.S. dollars and $1.1 billion of U.S. dollar equivalent Canadian dollars. Of these commitments, $425 million matured on or before October 25, 2021 and the remaining $1.138 billion will mature by December 6, 2021.

Environmental Compliance Program Price Risk

We are exposed to market risk related to the volatility in the price of credits needed to comply with various governmental and regulatory environmental compliance programs. To manage this risk, we enter into contracts to purchase these credits as appropriate. Some of these contracts are derivative instruments; however, we elect the normal purchase exception and do not record these contracts at their fair values. Certain of these programs, such as the biofuels programs described in Note 13, require us to blend biofuels into the products we produce, and we are subject to such programs in most of the countries in which we operate. These countries, or local governments thereof, set annual quotas for the percentage of biofuels that must be blended into the motor fuels consumed in their jurisdictions. As a producer of motor fuels from petroleum, we are obligated to blend biofuels into the products we produce at a rate that is at least equal to the applicable quota. To the degree we are unable to blend at the applicable rate, we must purchase biofuel credits (primarily RINs in the U.S.). We are exposed to

the volatility in the market price of these credits, and we manage that risk by purchasing biofuel credits as appropriate. The cost of meeting our credit obligations under the biofuels programs was $618 million and $143 million for the three months ended September 30, 2021 and 2020, respectively, and $1.6 billion and $391 million for the nine months ended September 30, 2021 and 2020, respectively. These amounts are reflected in cost of materials and other.

We are subject to additional requirements under the other environmental emissions programs as discussed in Note 13. Under these other environmental emissions programs, we purchase various emission credits to comply with these programs. Therefore, we are exposed to the volatility in the market price of these credits. The cost of the various credits under the other environmental emissions programs are significant; however, we recovered substantially all of these costs from our customers for the three and nine months ended September 30, 2021 and 2020 and expect to continue to recover the majority of these costs in the future. For the three and nine months ended September 30, 2021 and 2020, the net cost of meeting our credit obligations under these other environmental emissions programs was immaterial.

Fair Values of Derivative Instruments

The following tables provide information about the fair values of our derivative instruments as of September 30, 2021 and December 31, 2020 (in millions) and the line items in the balance sheets in which the fair values are reflected. See Note 13 for additional information related to the fair values of our derivative instruments.

As indicated in Note 13, we net fair value amounts recognized for multiple similar derivative contracts executed with the same counterparty under master netting arrangements, including cash collateral assets and obligations. The following table, however, is presented on a gross asset and gross liability basis, which results in the reflection of certain assets in liability accounts and certain liabilities in asset accounts:

Total		$	777	$	705	$	412	$	392

Market Risk

Our price risk management activities involve the receipt or payment of fixed price commitments into the future. These transactions give rise to market risk, which is the risk that future changes in market conditions may make an instrument less valuable. We closely monitor and manage our exposure to market risk on a daily basis in accordance with policies approved by our board of directors. Market risks are monitored by our risk control group to ensure compliance with our stated risk management policy. We do not require any collateral or other security to support derivative instruments into which we enter. We also do not have any derivative instruments that require us to maintain a minimum investment-grade credit rating.

Effect of Derivative Instruments on Income and Other Comprehensive Income (Loss)

The following table provides information about the gain (loss) recognized in income and other comprehensive income (loss) due to fair value adjustments of our cash flow hedges (in millions):

Derivatives in Cash Flow Hedging Relationships	Location of Gain (Loss) Recognized in Income on Derivatives	Three Months Ended September 30,				Nine Months Ended September 30,

Gain (loss) reclassified from accumulated other comprehensive loss into income	Revenues	(3)		(3)		(37)		42

For cash flow hedges, no component of any derivative instrument’s gains or losses was excluded from the assessment of hedge effectiveness for the three and nine months ended September 30, 2021 and 2020. For the three and nine months ended September 30, 2021 and 2020, cash flow hedges primarily related to forward sales of renewable diesel. The estimated deferred after-tax loss that is expected to be reclassified into revenues over the next 12 months as a result of the hedged transactions that are forecasted to occur as of September 30, 2021 was immaterial. For the three and nine months ended September 30, 2021 and 2020, there were no amounts reclassified from accumulated other comprehensive loss into income as a result of the discontinuance of cash flow hedge accounting. The changes in accumulated other comprehensive loss by component, net of tax, for the three and nine months ended September 30, 2021 and 2020 are described in Note 6.

Variable interest entities

We consolidate a VIE when we have a variable interest in an entity for which we are the primary beneficiary.We hold variable interests in VIEs that have not been consolidated because we are not considered the primary beneficiary. These non-consolidated VIEs are not material to our financial position or results of operations and are accounted for as equity investments.

Offsetting fair value amounts of commodity derivative contracts

We have elected to offset the fair value amounts recognized for multiple similar derivative contracts executed with the same counterparty, including any related cash collateral assets or obligations as shown below; however, fair value amounts by hierarchy level are presented in the following tables on a gross basis. We have no derivative contracts that are subject to master netting arrangements that are reflected gross on the balance sheet.

Derivatives

We are exposed to market risks primarily related to the volatility in the price of commodities, foreign currency exchange rates, and the price of credits needed to comply with various government and regulatory programs. We enter into derivative instruments to manage some of these risks, including derivative instruments related to the various commodities we purchase or produce, and foreign currency exchange and purchase contracts, as described below under “Risk Management Activities by Type of Risk.” These derivative instruments are recorded as either assets or liabilities measured at their fair values (see Note 13), as summarized below under “Fair Values of Derivative Instruments.” The effect of these derivative instruments on our income and other comprehensive income (loss) is summarized below under “Effect of Derivative Instruments on Income and Other Comprehensive Income (Loss).”

Derivative instruments collateral requirements

We do not require any collateral or other security to support derivative instruments into which we enter.
