Notes to Consolidated Financial Statements (Unaudited) Note 1 – General, Description of Business, and Basis of Presentation General Our accompanying interim consolidated financial statements do not include all the notes in our annual financial statements and, therefore, should be read in conjunction with the consolidated financial statements and notes thereto for the year ended December 31, 2020, in our Annual Report on Form 10-K. The accompanying unaudited financial statements include all normal recurring adjustments and others that, in the opinion of management, are necessary to present fairly our interim financial statements. The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results could differ from those estimates. Unless the context clearly indicates otherwise, references in this report to “Williams,” “we,” “our,” “us,” or like terms refer to The Williams Companies, Inc. and its subsidiaries. Unless the context clearly indicates otherwise, references to “Williams,” “we,” “our,” and “us” include the operations in which we own interests accounted for as equity-method investments that are not consolidated in our financial statements. When we refer to our equity investees by name, we are referring exclusively to their businesses and operations. Description of Business We are a Delaware corporation whose common stock is listed and traded on the New York Stock Exchange. Our operations are located in the United States and are presented within the following reportable segments: Transmission & Gulf of Mexico, Northeast G&P, and West, consistent with the manner in which our chief operating decision maker evaluates performance and allocates resources. All remaining business activities, including our recently acquired upstream operations, as well as corporate activities are included in Other. Transmission & Gulf of Mexico is comprised of our interstate natural gas pipelines, Transcontinental Gas Pipe Line Company, LLC (Transco) and Northwest Pipeline LLC (Northwest Pipeline), as well as natural gas gathering and processing and crude oil production handling and transportation assets in the Gulf Coast region, including a 51 percent interest in Gulfstar One LLC (Gulfstar One) (a consolidated variable interest entity, or VIE), which is a proprietary floating production system, a 50 percent equity-method investment in Gulfstream Natural Gas System, L.L.C., and a 60 percent equity-method investment in Discovery Producer Services LLC (Discovery). Northeast G&P is comprised of our midstream gathering, processing, and fractionation businesses in the Marcellus Shale region primarily in Pennsylvania and New York, and the Utica Shale region of eastern Ohio, as well as a 65 percent interest in Ohio Valley Midstream LLC (Northeast JV) (a consolidated VIE) which operates in West Virginia, Ohio, and Pennsylvania, a 66 percent interest in Cardinal Gas Services, L.L.C. (Cardinal) (a consolidated VIE) which operates in Ohio, a 69 percent equity-method investment in Laurel Mountain Midstream, LLC (Laurel Mountain), a 50 percent equity-method investment in Blue Racer Midstream LLC (Blue Racer) (we previously effectively owned a 29 percent indirect interest in Blue Racer through our 58 percent equity-method investment in Caiman Energy II, LLC (Caiman II) until acquiring a controlling interest of Caiman II in November 2020), and Appalachia Midstream Services, LLC, a wholly owned subsidiary that owns equity-method investments with an approximate average 66 percent interest in multiple gas gathering systems in the Marcellus Shale region (Appalachia Midstream Investments). West is comprised of our gas gathering, processing, and treating operations in the Rocky Mountain region of Colorado and Wyoming, the Barnett Shale region of north-central Texas, the Eagle Ford Shale region of south Texas, the Haynesville Shale region of northwest Louisiana, and the Mid-Continent region which includes the 12 Notes (Continued) Anadarko and Permian basins. This segment also includes our natural gas liquid (NGL) and natural gas marketing business, storage facilities, an undivided 50 percent interest in an NGL fractionator near Conway, Kansas, a 50 percent equity-method investment in Overland Pass Pipeline Company LLC, a 50 percent equity-method investment in Rocky Mountain Midstream Holdings LLC (RMM), a 20 percent equity-method investment in Targa Train 7 LLC (Targa Train 7) (a nonconsolidated VIE), and a 15 percent interest in Brazos Permian II, LLC (Brazos Permian II) (a nonconsolidated VIE). Basis of Presentation Significant risks and uncertainties We believe that the carrying value of certain of our property, plant, and equipment and other identifiable intangible assets, notably certain acquired assets accounted for as business combinations between 2012 and 2014, may be in excess of current fair value. However, the carrying value of these assets, in our judgment, continues to be recoverable. It is reasonably possible that future strategic decisions, including transactions such as monetizing non-core assets or contributing assets to new ventures with third parties, as well as unfavorable changes in expected producer activities, could impact our assumptions and ultimately result in impairments of these assets. Such transactions or developments may also indicate that certain of our equity-method investments have experienced other-than-temporary declines in value, which could result in impairment. Note 2 – Variable Interest Entities Consolidated VIEs As of June 30, 2021, we consolidate the following VIEs: Northeast JV We own a 65 percent interest in the Northeast JV, a subsidiary that is a VIE due to certain of our voting rights being disproportionate to our obligation to absorb losses and substantially all of the Northeast JV’s activities being performed on our behalf. We are the primary beneficiary because we have the power to direct the activities that most significantly impact the Northeast JV’s economic performance. The Northeast JV provides midstream services for producers in the Marcellus Shale and Utica Shale regions. Future expansion activity is expected to be funded with capital contributions from us and the other equity partner on a proportional basis. Gulfstar One We own a 51 percent interest in Gulfstar One, a subsidiary that, due to certain risk-sharing provisions in its customer contracts, is a VIE. Gulfstar One includes a proprietary floating production system, Gulfstar FPS, and associated pipelines that provide production handling and gathering services in the eastern deepwater Gulf of Mexico. We are the primary beneficiary because we have the power to direct the activities that most significantly impact Gulfstar One’s economic performance. Cardinal We own a 66 percent interest in Cardinal, a subsidiary that provides gathering services for the Utica Shale region and is a VIE due to certain risks shared with customers. We are the primary beneficiary because we have the power to direct the activities that most significantly impact Cardinal’s economic performance. Future expansion activity is expected to be funded with capital contributions from us and the other equity partner on a proportional basis. 13 Notes (Continued) The following table presents amounts included in the Consolidated Balance Sheet that are only for the use or obligation of our consolidated VIEs: June 30, 2021 December 31, 2020 (Millions) Assets (liabilities): Cash and cash equivalents $ 81 $ 107 Trade accounts and other receivables – net 151 148 Other current assets and deferred charges 9 7 Property, plant, and equipment – net 5,406 5,514 Intangible assets – net of accumulated amortization 2,322 2,376 Regulatory assets, deferred charges, and other 15 15 Accounts payable ( 55 ) ( 42 ) Accrued liabilities ( 39 ) ( 34 ) Regulatory liabilities, deferred income, and other ( 286 ) ( 289 ) Nonconsolidated VIEs Targa Train 7 We own a 20 percent interest in Targa Train 7, which provides fractionation services at Mt. Belvieu and is a VIE due primarily to our limited participating rights as the minority equity holder. At June 30, 2021, the carrying value of our investment in Targa Train 7 was $ 49 million. Our maximum exposure to loss is limited to the carrying value of our investment. Brazos Permian II We own a 15 percent interest in Brazos Permian II, which provides gathering and processing services in the Delaware basin and is a VIE due primarily to our limited participating rights as the minority equity holder. During the first quarter of 2020 we recorded an impairment of our equity-method investment in Brazos Permian II. Our maximum exposure to loss is limited to the carrying value of our investment. 14 Notes (Continued) Note 3 – Revenue Recognition Revenue by Category The following table presents our revenue disaggregated by major service line: Transco Northwest Pipeline Gulf of Mexico Midstream Northeast Midstream West Midstream Other Eliminations Total (Millions) Three Months Ended June 30, 2021 Revenues from contracts with customers: Service revenues: Regulated interstate natural gas transportation and storage $ 613 $ 108 $ — $ — $ — $ — $ ( 2 ) $ 719 Gathering, processing, transportation, fractionation, and storage: Monetary consideration — — 90 315 278 — ( 26 ) 657 Commodity consideration — — 10 2 39 — — 51 Other 2 — 7 52 10 — ( 4 ) 67 Total service revenues 615 108 107 369 327 — ( 32 ) 1,494 Product sales 16 — 53 24 726 44 ( 87 ) 776 Total revenues from contracts with customers 631 108 160 393 1,053 44 ( 119 ) 2,270 Other revenues (1) — — 3 6 ( 1 ) 8 ( 3 ) 13 Total revenues $ 631 $ 108 $ 163 $ 399 $ 1,052 $ 52 $ ( 122 ) $ 2,283 Three Months Ended June 30, 2020 Revenues from contracts with customers: Service revenues: Regulated interstate natural gas transportation and storage $ 592 $ 110 $ — $ — $ — $ — $ ( 1 ) $ 701 Gathering, processing, transportation, fractionation, and storage: Monetary consideration — — 78 308 297 — ( 19 ) 664 Commodity consideration — — 3 1 21 — — 25 Other 2 — 10 41 17 — ( 4 ) 66 Total service revenues 594 110 91 350 335 — ( 24 ) 1,456 Product sales 20 — 17 1 303 — ( 31 ) 310 Total revenues from contracts with customers 614 110 108 351 638 — ( 55 ) 1,766 Other revenues (1) 2 — 1 5 2 9 ( 4 ) 15 Total revenues $ 616 $ 110 $ 109 $ 356 $ 640 $ 9 $ ( 59 ) $ 1,781 15 Notes (Continued) Transco Northwest Pipeline Gulf of Mexico Midstream Northeast Midstream West Midstream Other Eliminations Total (Millions) Six Months Ended June 30, 2021 Revenues from contracts with customers: Service revenues: Regulated interstate natural gas transportation and storage $ 1,238 $ 221 $ — $ — $ — $ — $ ( 5 ) $ 1,454 Gathering, processing, transportation, fractionation, and storage: Monetary consideration — — 176 626 540 — ( 47 ) 1,295 Commodity consideration — — 21 5 74 — — 100 Other 5 — 10 93 29 — ( 8 ) 129 Total service revenues 1,243 221 207 724 643 — ( 60 ) 2,978 Product sales 30 — 106 56 1,806 100 ( 177 ) 1,921 Total revenues from contracts with customers 1,273 221 313 780 2,449 100 ( 237 ) 4,899 Other revenues (1) 2 — 5 12 ( 32 ) 15 ( 6 ) ( 4 ) Total revenues $ 1,275 $ 221 $ 318 $ 792 $ 2,417 $ 115 $ ( 243 ) $ 4,895 Six Months Ended June 30, 2020 Revenues from contracts with customers: Service revenues: Regulated interstate natural gas transportation and storage $ 1,196 $ 225 $ — $ — $ — $ — $ ( 3 ) $ 1,418 Gathering, processing, transportation, fractionation, and storage: Monetary consideration — — 177 620 596 — ( 41 ) 1,352 Commodity consideration — — 8 3 42 — — 53 Other 5 — 16 82 26 — ( 9 ) 120 Total service revenues 1,201 225 201 705 664 — ( 53 ) 2,943 Product sales 40 — 49 30 662 — ( 60 ) 721 Total revenues from contracts with customers 1,241 225 250 735 1,326 — ( 113 ) 3,664 Other revenues (1) 2 — 3 10 5 17 ( 7 ) 30 Total revenues $ 1,243 $ 225 $ 253 $ 745 $ 1,331 $ 17 $ ( 120 ) $ 3,694 ______________________________ (1) Revenues not derived from contracts with customers consist of leasing revenues associated with our headquarters building and management fees that we receive for certain services we provide to operated equity-method investments, which are reported in Service revenues in the Consolidated Statement of Operations, and amounts associated with our derivative contracts, which are reported in Product sales in the Consolidated Statement of Operations. 16 Notes (Continued) Contract Assets The following table presents a reconciliation of our contract assets: Three Months Ended June 30, Six Months Ended June 30, 2021 2020 2021 2020 (Millions) Balance at beginning of period $ 25 $ 18 $ 12 $ 8 Revenue recognized in excess of amounts invoiced 38 46 83 69 Minimum volume commitments invoiced ( 25 ) ( 34 ) ( 57 ) ( 47 ) Balance at end of period $ 38 $ 30 $ 38 $ 30 Contract Liabilities The following table presents a reconciliation of our contract liabilities: Three Months Ended June 30, Six Months Ended June 30, 2021 2020 2021 2020 (Millions) Balance at beginning of period $ 1,171 $ 1,189 $ 1,209 $ 1,215 Payments received and deferred 72 74 85 102 Significant financing component 2 2 5 5 Recognized in revenue ( 52 ) ( 62 ) ( 106 ) ( 119 ) Balance at end of period $ 1,193 $ 1,203 $ 1,193 $ 1,203 Remaining Performance Obligations Remaining performance obligations primarily include reservation charges on contracted capacity for our gas pipeline firm transportation contracts with customers, storage capacity contracts, long-term contracts containing minimum volume commitments associated with our midstream businesses, and fixed payments associated with offshore production handling. For our interstate natural gas pipeline businesses, remaining performance obligations reflect the rates for such services in our current Federal Energy Regulatory Commission (FERC) tariffs for the life of the related contracts; however, these rates may change based on future tariffs approved by the FERC and the amount and timing of these changes are not currently known. Our remaining performance obligations exclude variable consideration, including contracts with variable consideration for which we have elected the practical expedient for consideration recognized in revenue as billed. Certain of our contracts contain evergreen and other renewal provisions for periods beyond the initial term of the contract. The remaining performance obligation amounts as of June 30, 2021, do not consider potential future performance obligations for which the renewal has not been exercised and exclude contracts with customers for which the underlying facilities have not received FERC authorization to be placed into service. Consideration received prior to June 30, 2021, that will be recognized in future periods is also excluded from our remaining performance obligations and is instead reflected in contract liabilities. 17 Notes (Continued) The following table presents the amount of the contract liabilities balance expected to be recognized as revenue when performance obligations are satisfied and the transaction price allocated to the remaining performance obligations under certain contracts as of June 30, 2021. Contract Liabilities Remaining Performance Obligations (Millions) 2021 ( six months ) $ 83 $ 1,724 2022 ( one year ) 130 3,409 2023 ( one year ) 111 3,137 2024 ( one year ) 106 2,723 2025 ( one year ) 101 2,330 Thereafter 662 18,055 Total $ 1,193 $ 31,378 Accounts Receivable The following is a summary of our Trade accounts and other receivables – net : June 30, 2021 December 31, 2020 (Millions) Accounts receivable related to revenues from contracts with customers $ 928 $ 892 Other accounts receivable 71 107 Trade accounts and other receivables – net $ 999 $ 999 Note 4 – Investing Activities Equity Earnings (Losses) Equity earnings (losses) for the six months ended June 30, 2020, includes a $ 78 million loss associated with the first-quarter 2020 full impairment of goodwill recognized by our investee RMM, which was allocated entirely to our member interest per the terms of the membership agreement. Impairment of Equity-Method Investments Impairment of equity-method investments for the six months ended June 30, 2020, includes $ 938 million associated with the first-quarter 2020 impairment of certain equity-method investments (see Note 10 – Fair Value Measurements and Guarantees). 18 Notes (Continued) Note 5 – Provision (Benefit) for Income Taxes The Provision (benefit) for income taxes includes: Three Months Ended June 30, Six Months Ended June 30, 2021 2020 2021 2020 (Millions) Current: Federal $ — $ — $ ( 2 ) $ ( 28 ) State 1 ( 1 ) — — 1 ( 1 ) ( 2 ) ( 28 ) Deferred: Federal 85 93 200 ( 41 ) State 33 25 62 ( 18 ) 118 118 262 ( 59 ) Provision (benefit) for income taxes $ 119 $ 117 $ 260 $ ( 87 ) The effective income tax rates for the total provision (benefit) for both the three and six months ended June 30, 2021 and 2020 are greater than the federal statutory rate, primarily due to the effect of state income taxes. During the next 12 months, we do not expect ultimate resolution of any unrecognized tax benefit associated with domestic or international matters to have a material impact on our unrecognized tax benefit position. Note 6 – Earnings (Loss) Per Common Share Three Months Ended June 30, Six Months Ended June 30, 2021 2020 2021 2020 (Dollars in millions, except per-share amounts; shares in thousands) Net income (loss) available to common stockholders $ 304 $ 303 $ 729 $ ( 215 ) Basic weighted-average shares 1,215,250 1,213,601 1,214,950 1,213,310 Effect of dilutive securities: Nonvested restricted stock units 2,208 980 2,385 — Stock options 18 — 9 — Diluted weighted-average shares (1) 1,217,476 1,214,581 1,217,344 1,213,310 Earnings (loss) per common share: Basic $ .25 $ .25 $ .60 $ ( .18 ) Diluted $ .25 $ .25 $ .60 $ ( .18 ) ______________________________ (1) For the six months ended June 30, 2020, 1.1 million weighted-average nonvested restricted stock units have been excluded from the computation of diluted earnings (loss) per common share as their inclusion would be antidilutive due to our loss available to common stockholders. 19 Notes (Continued) Note 7 – Employee Benefit Plans Net periodic benefit cost (credit) is as follows: Pension Benefits Three Months Ended June 30, Six Months Ended June 30, 2021 2020 2021 2020 (Millions) Components of net periodic benefit cost (credit): Service cost $ 7 $ 7 $ 15 $ 15 Interest cost 7 9 14 19 Expected return on plan assets ( 11 ) ( 14 ) ( 22 ) ( 27 ) Amortization of net actuarial loss 3 7 7 11 Net actuarial loss from settlements 1 2 1 8 Net periodic benefit cost (credit) $ 7 $ 11 $ 15 $ 26 Other Postretirement Benefits Three Months Ended June 30, Six Months Ended June 30, 2021 2020 2021 2020 (Millions) Components of net periodic benefit cost (credit): Interest cost $ 2 $ 1 $ 3 $ 3 Expected return on plan assets ( 3 ) ( 2 ) ( 5 ) ( 5 ) Reclassification to regulatory liability — — 1 1 Net periodic benefit cost (credit) $ ( 1 ) $ ( 1 ) $ ( 1 ) $ ( 1 ) The components of Net periodic benefit cost (credit) other than the Service cost component are included in Other income (expense) – net below Operating income (loss) in the Consolidated Statement of Operations. During the six months ended June 30, 2021, we contributed $ 3 million to our pension plans and $ 3 million to our other postretirement benefit plans. We presently anticipate making additional contributions of approximately $ 1 million to our pension plans and approximately $ 2 million to our other postretirement benefit plans in the remainder of 2021. Note 8 – Debt and Banking Arrangements Long-Term Debt Issuances and retirements On March 2, 2021, we completed a public offering of $ 900 million of 2.6 percent senior unsecured notes due 2031. Commercial Paper Program At June 30, 2021, no Commercial paper was outstanding under our $ 4 billion commercial paper program. 20 Notes (Continued) Credit Facilities June 30, 2021 Stated Capacity Outstanding (Millions) Long-term credit facility (1) $ 4,500 $ — Letters of credit under certain bilateral bank agreements 17 (1) In managing our available liquidity, we do not expect a maximum outstanding amount in excess of the capacity of our credit facility inclusive of any outstanding amounts under our commercial paper program. Note 9 – Stockholders’ Equity Stockholder Rights Agreement As disclosed in our Annual Report on Form 10-K filed February 24, 2021, a purported shareholder filed a putative class action lawsuit in the Delaware Court of Chancery challenging our stockholder rights agreement (Rights Agreement). On February 26, 2021, the Delaware Court of Chancery issued a decision which declared the Rights Agreement unenforceable and permanently enjoined the continued operation of the Rights Agreement, which otherwise would have expired on March 20, 2021. AOCI The following table presents the changes in AOCI by component, net of income taxes: Cash Flow Hedges Foreign Currency Translation Pension and Other Postretirement Benefits Total (Millions) Balance at December 31, 2020 $ ( 3 ) $ ( 1 ) $ ( 92 ) $ ( 96 ) Other comprehensive income (loss) before reclassifications ( 26 ) — — ( 26 ) Amounts reclassified from accumulated other comprehensive income (loss) 6 — 6 12 Other comprehensive income (loss) ( 20 ) — 6 ( 14 ) Balance at June 30, 2021 $ ( 23 ) $ ( 1 ) $ ( 86 ) $ ( 110 ) Reclassifications out of AOCI are presented in the following table by component for the six months ended June 30, 2021: Component Reclassifications Classification (Millions) Cash flow hedges: Energy commodity contracts $ 8 Product sales Pension and other postretirement benefits: Amortization of actuarial (gain) loss and net actuarial loss from settlements included in net periodic benefit cost (credit) 8 Other income (expense) – net below Operating income (loss) Income tax benefit ( 4 ) Provision (benefit) for income taxes Reclassifications during the period $ 12 21 Notes (Continued) Note 10 – Fair Value Measurements and Guarantees The following table presents, by level within the fair value hierarchy, certain of our significant financial assets and liabilities. The carrying values of cash and cash equivalents, accounts receivable, margin deposits, and accounts payable approximate fair value because of the short-term nature of these instruments. Therefore, these assets and liabilities are not presented in the following table. Fair Value Measurements Using Carrying Amount Fair Value Quoted Prices In Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) (Millions) Assets (liabilities) at June 30, 2021: Measured on a recurring basis: ARO Trust investments $ 257 $ 257 $ 257 $ — $ — Additional disclosures: Long-term debt, including current portion ( 23,234 ) ( 27,643 ) — ( 27,643 ) — Guarantees ( 40 ) ( 26 ) — ( 10 ) ( 16 ) Assets (liabilities) at December 31, 2020: Measured on a recurring basis: ARO Trust investments $ 235 $ 235 $ 235 $ — $ — Additional disclosures: Long-term debt, including current portion ( 22,344 ) ( 27,043 ) — ( 27,043 ) — Guarantees ( 40 ) ( 27 ) — ( 11 ) ( 16 ) Fair Value Methods We use the following methods and assumptions in estimating the fair value of our financial instruments: Assets measured at fair value on a recurring basis ARO Trust investments : Transco deposits a portion of its collected rates, pursuant to its rate case settlement, into an external trust (ARO Trust) that is specifically designated to fund future asset retirement obligations (ARO). The ARO Trust invests in a portfolio of actively traded mutual funds that are measured at fair value on a recurring basis based on quoted prices in an active market and is reported in Regulatory assets, deferred charges, and other in the Consolidated Balance Sheet. Both realized and unrealized gains and losses are ultimately recorded as regulatory assets or liabilities. Additional fair value disclosures Long-term debt, including current portion : The disclosed fair value of our long-term debt is determined primarily by a market approach using broker quoted indicative period-end bond prices. The quoted prices are based on observable transactions in less active markets for our debt or similar instruments. The fair values of the financing obligations associated with our Dalton lateral and Atlantic Sunrise projects, which are included within long-term debt, were determined using an income approach. Guarantees : Guarantees primarily consist of a guarantee we have provided in the event of nonpayment by our previously owned communications subsidiary, Williams Communications Group (WilTel), on a lease performance obligation that extends through 2042. Guarantees also include an indemnification related to a disposed operation. 22 Notes (Continued) To estimate the fair value of the WilTel guarantee, an estimated default rate is applied to the sum of the future contractual lease payments using an income approach. The estimated default rate is determined by obtaining the average cumulative issuer-weighted corporate default rate based on the credit rating of WilTel’s current owner and the term of the underlying obligation. The default rate is published by Moody’s Investors Service. The carrying value of the WilTel guarantee is reported in Accrued liabilities in the Consolidated Balance Sheet. The maximum potential undiscounted exposure is approximately $ 26 million at June 30, 2021. Our exposure declines systematically through the remaining term of WilTel’s obligation. The fair value of the guarantee associated with the indemnification related to a disposed operation was estimated using an income approach that considered probability-weighted scenarios of potential levels of future performance. The terms of the indemnification do not limit the maximum potential future payments associated with the guarantee. The carrying value of this guarantee is reported in Regulatory liabilities, deferred income, and other in the Consolidated Balance Sheet. We are required by our revolving credit agreement to indemnify lenders for certain taxes required to be withheld from payments due to the lenders and for certain tax payments made by the lenders. The maximum potential amount of future payments under these indemnifications is based on the related borrowings and such future payments cannot currently be determined. These indemnifications generally continue indefinitely unless limited by the underlying tax regulations and have no carrying value. We have never been called upon to perform under these indemnifications and have no current expectation of a future claim. Nonrecurring fair value measurements During the first quarter of 2020, we observed a significant decline in the publicly traded price of our common stock (NYSE: WMB), which declined 40 percent during the quarter, including a 26 percent decline in the month of March. These changes were generally attributed to macroeconomic and geopolitical conditions, including significant declines in crude oil prices driven by both surplus supply and a decrease in demand caused by the coronavirus (COVID-19) pandemic. As a result of these conditions, we performed an interim assessment of the goodwill associated with our Northeast G&P reporting unit as of March 31, 2020. The assessment considered the total fair value of the businesses within the Northeast G&P reporting unit, which was determined using income and market approaches. We utilized internally developed industry weighted-average discount rates and estimates of valuation multiples of comparable publicly traded gathering and processing companies. In assessing the fair value as of the March 31, 2020 measurement date, we were required to consider recent publicly available indications of value, which included lower observed publicly traded EBITDA (earnings before interest, taxes, depreciation, and amortization) market multiples as compared with recent history and significantly higher industry weighted-average discount rates. The fair value of the reporting unit was further reconciled to our estimated total enterprise value as of March 31, 2020, which considered observable valuation multiples of comparable publicly traded companies applied to each distinct business including the Northeast G&P reporting unit. This assessment indicated that the estimated fair value of the Northeast G&P reporting unit was below its carrying value, including goodwill. As a result of this Level 3 measurement, we recognized a full impairment charge of $ 187 million as of March 31, 2020, in Impairment of goodwill in the Consolidated Statement of Operations. Our partner’s $ 65 million share of this impairment is reflected within Net income (loss) attributable to noncontrolling interests in the Consolidated Statement of Operations. 23 Notes (Continued) The following table presents impairments of equity-method investments associated with certain nonrecurring fair value measurements within Level 3 of the fair value hierarchy. Impairments Six Months Ended June 30, Segment Date of Measurement Fair Value 2021 2020 (Millions) Impairment of equity-method investments: RMM (1) West March 31, 2020 $ 557 $ 243 Brazos Permian II (1) West March 31, 2020 — 193 Caiman II (2) Northeast G&P March 31, 2020 191 229 Appalachia Midstream Investments (2) Northeast G&P March 31, 2020 2,700 127 Aux Sable (2) Northeast G&P March 31, 2020 7 39 Laurel Mountain (2) Northeast G&P March 31, 2020 236 10 Discovery (2) Transmission & Gulf of Mexico March 31, 2020 367 97 Impairment of equity-method investments $ — $ 938 _______________ (1) Following the previously described declining market conditions during the first quarter of 2020, we evaluated these investments for other-than-temporary impairment. The fair value was measured using an income approach. Both investees operate in primarily oil-driven basins where significant expected reductions in producer activities led to reduced estimates of expected future cash flows. Our fair value estimates also reflected discount rates of approximately 17 percent for these investments. We also considered any debt held at the investee level, and its impact to fair value. The industry weighted-average discount rates utilized were significantly influenced by the market declines previously discussed. (2) Following the previously described declining market conditions during the first quarter of 2020, we evaluated these investments for other-than-temporary impairment. The impairments within our Northeast G&P segment are primarily associated with operations in wet-gas areas where producer drilling activities are influenced by NGL prices which historically trend with crude oil prices. The fair values of our investments in Caiman II and Aux Sable Liquid Products LP (Aux Sable) were estimated using a market approach, reflecting valuation multiples ranging from 5.0 x to 6.2 x EBITDA (weighted-average 6.0 x). The fair values of the other investments, including gathering systems that are part of Appalachia Midstream Investments, were estimated using an income approach, with discount rates ranging from 9.7 percent to 13.5 percent (weighted-average 12.6 percent). We also considered any debt held at the investee level, and its impact to fair value. The assumed valuation multiples and industry weighted-average discount rates utilized were both significantly influenced by the market declines previously discussed. Note 11 – Contingent Liabilities Reporting of Natural Gas-Related Information to Trade Publications Direct and indirect purchasers of natural gas in various states filed individual and class actions against us, our former affiliate WPX Energy, Inc. (WPX) and its subsidiaries, and others alleging the manipulation of published gas price indices and seeking unspecified amounts of damages. Such actions were transferred to the Nevada federal district court for consolidation of discovery and pre-trial issues. We have agreed to indemnify WPX and its subsidiaries related to this matter. 24 Notes (Continued) In the individual action, filed by Farmland Industries Inc. (Farmland), the court issued an order on May 24, 2016, granting one of our co-defendant’s motion for summary judgment as to Farmland’s claims. On January 5, 2017, the court extended such ruling to us, entering final judgment in our favor. Farmland appealed. On March 27, 2018, the appellate court reversed the district court’s grant of summary judgment, and on April 10, 2018, the defendants filed a petition for rehearing with the appellate court, which was denied on May 9, 2018. The case was remanded to the Nevada federal district court and subsequently remanded to its originally filed court, the Kansas federal district court where we re-urged our motion for summary judgment. The district court denied the motion but granted our request to seek permission for an immediate appeal to the appellate court. Oral argument occurred before the appellate court on January 19, 2021. On June 22, 2021, the appellate court ruled that we are not entitled to summary judgment and remanded the case to the Kansas federal district court. The court has scheduled trial to begin May 9, 2022. In the putative class actions, on March 30, 2017, the court issued an order denying the plaintiffs’ motions for class certification. On June 13, 2017, the United States Court of Appeals for the Ninth Circuit granted the plaintiffs’ petition for permission to appeal the order. On August 6, 2018, the Ninth Circuit reversed the order denying class certification and remanded the case to the Nevada federal district court. We reached an agreement to settle two of the actions, and on April 22, 2019, the Nevada federal district court preliminarily approved the settlements, which are on behalf of Kansas and Missouri class members. The final fairness hearing on the settlement occurred August 5, 2019, and a final judgment of dismissal with prejudice was entered the same day. Two putative class actions remain unresolved, and they have been remanded to their originally filed court, the Wisconsin federal district court. Trial was scheduled to begin June 14, 2021, but the court struck the setting and has not reset it. Because of the uncertainty around the remaining unresolved issues, we cannot reasonably estimate a range of potential exposure at this time. However, it is reasonably possible that the ultimate resolution of these actions and our related indemnification obligation could result in a potential loss that may be material to our results of operations. In connection with this indemnification, we have an accrued liability balance associated with this matter and have exposure to future developments. Alaska Refinery Contamination Litigation We are involved in litigation arising from our ownership and operation of the North Pole Refinery in North Pole, Alaska, from 1980 until 2004, through our wholly owned subsidiaries Williams Alaska Petroleum Inc. (WAPI) and MAPCO Inc. We sold the refinery to Flint Hills Resources Alaska, LLC (FHRA), a subsidiary of Koch Industries, Inc., in 2004. The litigation involves three cases, with filing dates ranging from 2010 to 2014. The actions primarily arise from sulfolane contamination allegedly emanating from the refinery. A putative class action lawsuit was filed by James West in 2010 naming us, WAPI, and FHRA as defendants. We and FHRA filed claims against each other seeking, among other things, contractual indemnification alleging that the other party caused the sulfolane contamination. In 2011, we and FHRA settled the claim with James West. Certain claims by FHRA against us were resolved by the Alaska Supreme Court in our favor. FHRA’s claims against us for contractual indemnification and statutory claims for damages related to off-site sulfolane were remanded to the Alaska Superior Court. The State of Alaska filed its action in March 2014, seeking damages. The City of North Pole (North Pole) filed its lawsuit in November 2014, seeking past and future damages, as well as punitive damages. Both we and WAPI asserted counterclaims against the State of Alaska and North Pole, and cross-claims against FHRA. FHRA has also filed cross-claims against us. The underlying factual basis and claims in the cases are similar and may duplicate exposure. As such, in February 2017, the three cases were consolidated into one action in state court containing the remaining claims from the James West case and those of the State of Alaska and North Pole. The State of Alaska later announced the discovery of additional contaminants per- and polyfluoralkyl (PFOS and PFOA) offsite of the refinery, and the court permitted the State of Alaska to amend its complaint to add a claim for offsite PFOS/PFOA contamination. The court subsequently remanded the offsite PFOS/PFOA claims to the Alaska Department of Environmental 25 Notes (Continued) Conservation for investigation and stayed the claims pending their potential resolution at the administrative agency. Several trial dates encompassing all three cases have been scheduled and stricken. In the summer of 2019, the court deconsolidated the cases for purposes of trial. A bench trial on all claims except North Pole’s claims began in October 2019. In January 2020, the Alaska Superior Court issued its Memorandum of Decision finding in favor of the State of Alaska and FHRA, with the total incurred and potential future damages estimated to be $ 86 million. The court found that FHRA is not entitled to contractual indemnification from us because FHRA contributed to the sulfolane contamination. On March 23, 2020, the court entered final judgment in the case. Filing deadlines were stayed until May 1, 2020. However, on April 21, 2020, we filed a Notice of Appeal. We also filed post-judgment motions including a Motion for New Trial and a Motion to Alter or Amend the Judgment. These post-trial motions were resolved with the court’s denial of the last motion on June 11, 2020. Our Statement of Points on Appeal was filed on July 13, 2020. On June 22, 2020, the court stayed the North Pole’s case pending resolution of the appeal in the State of Alaska and FHRA case. On December 23, 2020, we filed our opening brief on appeal. We have recorded an accrued liability in the amount of our estimate of the probable loss. It is reasonably possible that we may not be successful on appeal and could ultimately pay up to the amount of judgment. Royalty Matters Certain of our customers, including Chesapeake Energy Corporation (Chesapeake), have been named in various lawsuits alleging underpayment of royalties and claiming, among other things, violations of anti-trust laws and the Racketeer Influenced and Corrupt Organizations Act. We have also been named as a defendant in certain of these cases filed in Pennsylvania based on allegations that we improperly participated with Chesapeake in causing the alleged royalty underpayments. We believe that the claims asserted are subject to indemnity obligations owed to us by Chesapeake. Chesapeake has reached a settlement to resolve substantially all Pennsylvania royalty cases pending, which settlement applies to both Chesapeake and us. The settlement does not require any contribution from us and is awaiting court approval. Litigation Against Energy Transfer and Related Parties On April 6, 2016, we filed suit in Delaware Chancery Court against Energy Transfer Equity, L.P. (Energy Transfer) and LE GP, LLC (the general partner for Energy Transfer) alleging willful and material breaches of the Agreement and Plan of Merger (ETE Merger Agreement) with Energy Transfer resulting from the private offering by Energy Transfer on March 8, 2016, of Series A Convertible Preferred Units (Special Offering) to certain Energy Transfer insiders and other accredited investors. The suit seeks, among other things, an injunction ordering the defendants to unwind the Special Offering and to specifically perform their obligations under the ETE Merger Agreement. On April 19, 2016, we filed an amended complaint seeking the same relief. On May 3, 2016, Energy Transfer and LE GP, LLC filed an answer and counterclaims. On May 13, 2016, we filed a separate complaint in Delaware Chancery Court against Energy Transfer, LE GP, LLC and the other Energy Transfer affiliates that are parties to the ETE Merger Agreement, alleging material breaches of the ETE Merger Agreement for failing to cooperate and use necessary efforts to obtain a tax opinion required under the ETE Merger Agreement (Tax Opinion) and for otherwise failing to use necessary efforts to consummate the merger under the ETE Merger Agreement wherein we would be merged with and into the newly formed Energy Transfer Corp LP (ETC) (ETC Merger). The suit sought, among other things, a declaratory judgment and injunction preventing Energy Transfer from terminating or otherwise avoiding its obligations under the ETE Merger Agreement due to any failure to obtain the Tax Opinion. The Court of Chancery coordinated the Special Offering and Tax Opinion suits. On May 20, 2016, the Energy Transfer defendants filed amended affirmative defenses and verified counterclaims in the Special Offering and Tax Opinion suits, alleging certain breaches of the ETE Merger Agreement by us and seeking, among other things, a declaration that we were not entitled to specific performance, that Energy Transfer could terminate the ETC Merger, and that Energy Transfer is entitled to a $ 1.48 billion termination fee. On June 24, 2016, following a two-day trial, the court issued a Memorandum Opinion and Order denying our requested relief in the Tax Opinion suit. The court did not rule on the substance of our claims related to the Special Offering or on the substance of Energy Transfer’s 26 Notes (Continued) counterclaims. On June 27, 2016, we filed an appeal of the court’s decision with the Supreme Court of Delaware, seeking reversal and remand to pursue damages. On March 23, 2017, the Supreme Court of Delaware affirmed the Court of Chancery’s ruling. On March 30, 2017, we filed a motion for reargument with the Supreme Court of Delaware, which was denied on April 5, 2017. On September 16, 2016, we filed an amended complaint with the Court of Chancery seeking damages for breaches of the ETE Merger Agreement by defendants. On September 23, 2016, Energy Transfer filed a second amended and supplemental affirmative defenses and verified counterclaim with the Court of Chancery seeking, among other things, payment of the $ 1.48 billion termination fee due to our alleged breaches of the ETE Merger Agreement. On December 1, 2017, the court granted our motion to dismiss certain of Energy Transfer’s counterclaims, including its claim seeking payment of the $ 1.48 billion termination fee. On December 8, 2017, Energy Transfer filed a motion for reargument, which the Court of Chancery denied on April 16, 2018. The Court of Chancery originally scheduled trial for May 20 through May 24, 2019; the court struck that setting and reset trial to occur in 2020. All 2020 trial settings were struck due to COVID-19. Trial was held May 10 through May 17, 2021. Post-trial argument is scheduled for September 16, 2021. Environmental Matters We are a participant in certain environmental activities in various stages including assessment studies, cleanup operations, and/or remedial processes at certain sites, some of which we currently do not own. We are monitoring these sites in a coordinated effort with other potentially responsible parties, the U.S. Environmental Protection Agency (EPA), or other governmental authorities. We are jointly and severally liable along with unrelated third parties in some of these activities and solely responsible in others. Certain of our subsidiaries have been identified as potentially responsible parties at various Superfund and state waste disposal sites. In addition, these subsidiaries have incurred, or are alleged to have incurred, various other hazardous materials removal or remediation obligations under environmental laws. As of June 30, 2021, we have accrued liabilities totaling $ 31 million for these matters, as discussed below. Estimates of the most likely costs of cleanup are generally based on completed assessment studies, preliminary results of studies, or our experience with other similar cleanup operations. At June 30, 2021, certain assessment studies were still in process for which the ultimate outcome may yield different estimates of most likely costs. Therefore, the actual costs incurred will depend on the final amount, type, and extent of contamination discovered at these sites, the final cleanup standards mandated by the EPA or other governmental authorities, and other factors. The EPA and various state regulatory agencies routinely promulgate and propose new rules and issue updated guidance to existing rules. These rulemakings include, but are not limited to, rules for reciprocating internal combustion engine and combustion turbine maximum achievable control technology, air quality standards for one-hour nitrogen dioxide emissions, and volatile organic compound and methane new source performance standards impacting design and operation of storage vessels, pressure valves, and compressors. The EPA previously issued its rule regarding National Ambient Air Quality Standards for ground-level ozone. We are monitoring the rule’s implementation as it will trigger additional federal and state regulatory actions that may impact our operations. Implementation of the regulations is expected to result in impacts to our operations and increase the cost of additions to Property, plant, and equipment – net in the Consolidated Balance Sheet for both new and existing facilities in affected areas. We are unable to reasonably estimate the cost of additions that may be required to meet the regulations at this time due to uncertainty created by various legal challenges to these regulations and the need for further specific regulatory guidance. Continuing operations Our interstate gas pipelines are involved in remediation activities related to certain facilities and locations for polychlorinated biphenyls, mercury, and other hazardous substances. These activities have involved the EPA and various state environmental authorities, resulting in our identification as a potentially responsible party at various Superfund waste sites. At June 30, 2021, we have accrued liabilities of $ 4 million for these costs. We expect that these costs will be recoverable through rates. 27 Notes (Continued) We also accrue environmental remediation costs for natural gas underground storage facilities, primarily related to soil and groundwater contamination. At June 30, 2021, we have accrued liabilities totaling $ 8 million for these costs. Former operations We have potential obligations in connection with assets and businesses we no longer operate. These potential obligations include remediation activities at the direction of federal and state environmental authorities and the indemnification of the purchasers of certain of these assets and businesses for environmental and other liabilities existing at the time the sale was consummated. Our responsibilities relate to the operations of the assets and businesses described below. • Former agricultural fertilizer and chemical operations and former retail petroleum and refining operations; • Former petroleum products and natural gas pipelines; • Former petroleum refining facilities; • Former exploration and production and mining operations; • Former electricity and natural gas marketing and trading operations. At June 30, 2021, we have accrued environmental liabilities of $ 19 million related to these matters. Other Divestiture Indemnifications Pursuant to various purchase and sale agreements relating to divested businesses and assets, we have indemnified certain purchasers against liabilities that they may incur with respect to the businesses and assets acquired from us. The indemnities provided to the purchasers are customary in sale transactions and are contingent upon the purchasers incurring liabilities that are not otherwise recoverable from third parties. The indemnities generally relate to breach of warranties, tax, historic litigation, personal injury, property damage, environmental matters, right of way, and other representations that we have provided. At June 30, 2021, other than as previously disclosed, we are not aware of any material claims against us involving the above-described indemnities; thus, we do not expect any of the indemnities provided pursuant to the sales agreements to have a material impact on our future financial position. Any claim for indemnity brought against us in the future may have a material adverse effect on our results of operations in the period in which the claim is made. In addition to the foregoing, various other proceedings are pending against us that are incidental to our operations, none of which are expected to be material to our expected future annual results of operations, liquidity, and financial position. Summary We have disclosed our estimated range of reasonably possible losses for certain matters above, as well as all significant matters for which we are unable to reasonably estimate a range of possible loss. We estimate that for all other matters for which we are able to reasonably estimate a range of loss, our aggregate reasonably possible losses beyond amounts accrued are immaterial to our expected future annual results of operations, liquidity, and financial position. These calculations have been made without consideration of any potential recovery from third parties. Note 12 – Segment Disclosures Our reportable segments are Transmission & Gulf of Mexico, Northeast G&P, and West. All remaining business activities are included in Other. (See Note 1 – General, Description of Business, and Basis of Presentation.) 28 Notes (Continued) Performance Measurement We evaluate segment operating performance based upon Modified EBITDA . This measure represents the basis of our internal financial reporting and is the primary performance measure used by our chief operating decision maker in measuring performance and allocating resources among our reportable segments. Intersegment Service revenues primarily represent transportation services provided to our marketing business and gathering services provided to our oil and gas properties. Intersegment Product sales primarily represent the sale of NGLs from our natural gas processing plants and our oil and gas properties to our marketing business. We define Modified EBITDA as follows: • Net income (loss) before: ◦ Provision (benefit) for income taxes; ◦ Interest incurred, net of interest capitalized; ◦ Equity earnings (losses); ◦ Impairment of equity-method investments; ◦ Other investing income (loss) – net; ◦ Impairment of goodwill; ◦ Depreciation and amortization expenses; ◦ Accretion expense associated with asset retirement obligations for nonregulated operations. • This measure is further adjusted to include our proportionate share (based on ownership interest) of Modified EBITDA from our equity-method investments calculated consistently with the definition described above. 29 Notes (Continued) The following table reflects the reconciliation of Segment revenues to Total revenues as reported in the Consolidated Statement of Operations and Total assets by reportable segment.

In February 2021, we acquired properties in the Wamsutter field in Wyoming from a supermajor oil and gas company for approximately $ 79 million, a portion of which was paid in the prior year. We recorded $ 290 million of property, plant, and equipment and $ 207 million of ARO related to this transaction. In June 2021, we acquired additional properties also in the Wamsutter field in Wyoming from an oil and gas company for approximately $ 86 million in cash, which is net of approximately $ 48 million reflecting the full settlement of outstanding receivables. We recorded $ 257 million of property, plant, and equipment and $ 125 million of ARO related to this transaction. Our oil and gas exploration and production activities are accounted for under the successful efforts method. 31 Notes (Continued) The following table reflects the reconciliation of Modified EBITDA to Net income (loss) as reported in the Consolidated Statement of Operations.

(collectively, Sequent). Total consideration paid was $ 134 million, which includes $ 84 million of working capital acquired, and is subject to post-closing adjustment. Sequent focuses on asset management and the wholesale marketing, trading, storage, and transportation of natural gas for a diverse set of natural gas utilities and producers, and moves gas to markets through transportation and storage agreements on strategically positioned assets, including along our Transco system. Due to the recent closing of this acquisition, we have not provided all required disclosures as the information necessary is still under development. We plan to provide these disclosures in future filings. 32
