Such statements are “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933, as amended (Securities Act), and Section 21E of the Securities Exchange Act of 1934, as amended (Exchange Act). These forward-looking statements relate to anticipated financial performance, management’s plans and objectives for future operations, business prospects, outcome of regulatory proceedings, market conditions, and other matters.
All statements, other than statements of historical facts, included in this report that address activities, events, or developments that we expect, believe, or anticipate will exist or may occur in the future are forward-looking statements. Forward-looking statements can be identified by various forms of words such as “anticipates,” “believes,” “seeks,” “could,” “may,” “should,” “continues,” “estimates,” “expects,” “forecasts,” “intends,” “might,” “goals,” “objectives,” “targets,” “planned,” “potential,” “projects,” “scheduled,” “will,” “assumes,” “guidance,” “outlook,” “in-service date,” or other similar expressions.

The impact of the coronavirus (COVID-19) pandemic.
Forward-looking statements are based on numerous assumptions, uncertainties, and risks that could cause future events or results to be materially different from those stated or implied in this report. Many of the factors that will determine these results are beyond our ability to control or predict. Specific factors that could cause actual results to differ from results contemplated by the forward-looking statements include, among others, the following:

The impact of operational and developmental hazards and unforeseen interruptions;

Development and rate of adoption of alternative energy sources;

The strength and financial resources of our competitors and the effects of competition;

Availability of supplies, including lower than anticipated volumes from third parties, and market demand;

Volatility of pricing including the effect of lower than anticipated energy commodity prices;

Changes in maintenance and construction costs, as well as our ability to obtain sufficient construction- related inputs, including skilled labor;

The impact of existing and future laws and regulations, the regulatory environment, environmental matters, and litigation, as well as our ability to obtain necessary permits and approvals, and achieve favorable rate proceeding outcomes;

Increasing scrutiny and changing expectations from stakeholders with respect to our environmental, social, and governance practices;

The physical and financial risks associated with climate change;

Our exposure to the credit risk of our customers and counterparties;

Our ability to successfully expand our facilities and operations;

Whether we are able to successfully identify, evaluate, and timely execute our capital projects and investment opportunities;

Risks related to financing, including restrictions stemming from debt agreements, future changes in credit ratings as determined by nationally recognized credit rating agencies, and the availability and cost of capital;

Inflation, interest rates, and general economic conditions (including future disruptions and volatility in the global credit markets and the impact of these events on customers and suppliers);

The risks resulting from outbreaks or other public health crises, including COVID-19;

Changes in the current geopolitical situation;situation, including the Russian invasion of Ukraine;

Changes in U.S. governmental administration and policies;

Risks associated with weather and natural phenomena, including climate conditions and physical damage to our facilities;

Acts of terrorism, cybersecurity incidents, and related disruptions; and

Additional risks described in our filings with the Securities and Exchange Commission (SEC).
Given the uncertainties and risk factors that could cause our actual results to differ materially from those contained in any forward-looking statement, we caution investors not to unduly rely on our forward-looking statements. We disclaim any obligations to and do not intend to update the above list or announce publicly the result of any revisions to any of the forward-looking statements to reflect future events or developments.
In addition to causing our actual results to differ, the factors listed above and referred to below may cause our intentions to change from those statements of intention set forth in this report. Such changes in our intentions may also cause our results to differ. We may change our intentions, at any time and without notice, based upon changes in such factors, our assumptions, or otherwise.
Because forward-looking statements involve risks and uncertainties, we caution that there are important factors, in addition to those listed above, that may cause actual results to differ materially from those contained in the forward-looking statements. For a detailed discussion of those factors, see Part I, Item 1A. Risk Factors in our Annual Report on Form 10-K for the year ended December 31, 2020,2021, as filed with the SEC on February 24, 2021.28, 2022, as supplemented by disclosures in Part II, Item 1A.

Remaining Performance Obligations

Our remaining performance obligations primarily include reservation charges on contracted capacity on our firm transportation and storage contracts with customers. Amounts from certain contracts included in the table below, which are subject to periodic review and approval by the Federal Energy Regulatory Commission (FERC),FERC, reflect the rates for such services in our current FERC tariffs, net of estimated reserve for refund, 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 is not currently known.FERC. This table excludes the variable consideration component for commodity charges. Certain of our contracts contain evergreen and other renewal provisions for periods beyond the initial term of the contract. The remaining performance obligations as of SeptemberJune 30, 2021,2022 do not consider potential future performance obligations for which the renewal has not been exercised. The table below also does not includeexercised and exclude contracts with customers for which the underlying facilities have not received FERC authorization to be placed into service.

Note 3 – Contingent Liabilities and Commitments

Environmental Matters

We have had studies underway for many years to test some of our facilities for the presence of toxic and hazardous substances such as polychlorinated biphenyls (PCBs) and mercury to determine to what extent, if any, remediation may be necessary. We have also similarly evaluated past on-site disposal of hydrocarbons at a number of our facilities. We have worked closely with and responded to data requests from the U.S. Environmental Protection Agency (EPA) and state agencies regarding such potential contamination of certain of our sites. We are conducting environmental assessments and implementing a variety of remedial measures that may result in increases or decreases in the total estimated costs. At SeptemberJune 30, 2022, we had a balance of approximately $2.7 million for the expense portion of these estimated costs, $0.9 million recorded in Accrued liabilities- Other and $1.8 million recorded in Other Long-Term Liabilities - Other on the Balance Sheet. At December 31, 2021, we have accruedhad a balance of approximately $2.6$2.5 million for the expense portion of these estimated costs, $0.7 million of which is recorded in Accrued liabilities - Otherand $1.9$1.8 million of which is recorded in Other Long-Term Liabilities - Other inon the accompanying Condensed Balance Sheet. At December 31, 2020, we had a balance of approximately $2.4 million for the expense portion of these estimated costs, $0.7 million of which is recorded in Accrued liabilities and $1.7 million of which is recorded in Other Long-Term Liabilities - Other in the accompanying Condensed Balance Sheet.

Notes (Continued)

We have been identified as a potentially responsible party (PRP) at various Superfund and state waste disposal sites. Based on present volumetric estimates and other factors, our estimated aggregate exposure for remediation of these sites is less than $0.5 million. The estimated remediation costs for all of these sites are included in the environmental liabilities discussed above. Liability under the Comprehensive Environmental Response, Compensation and Liability Act and applicable state law can be joint and several with other PRPs. Although volumetric allocation is a factor in assessing liability, it is not necessarily determinative; thus, the ultimate liability could be substantially greater than the amounts described above.

The EPA and various state regulatory agencies routinely propose and promulgate 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, review and updates to the National Ambient Air Quality Standards, and rules for new and existing source performance standards for volatile organic compounds and methane. We continuously monitor these regulatory changes and how they may impact our operations. Implementation of new or modified regulations may result in impacts to our operations and increase the cost additions to Property,Total property, plant, and equipment, net in on the Condensed Balance Sheet for both new and existing facilities in affected areas; however, due to regulatory uncertainty on final rule content and applicability timeframes, we are unable to reasonably estimate the cost of these regulatory impacts at this time.

We consider prudently incurred environmental assessment and remediation costs and the costs associated with compliance with environmental standards to be recoverable through rates. To date, we have been permitted recovery of environmental costs, and it is our intent to continue seeking recovery of such costs through future rate filings.

Other Matters

Various other proceedings are pending against us and are considered incidental to our operations.

Summary

We have disclosed all significant matters for which we are unable to reasonably estimate a range of possible loss. We estimate that for all matters for which we are able to reasonably estimate a range of loss, including those noted above and others that are not individually significant, our aggregate reasonably possible losses beyond amounts accrued for all of our contingent liabilities 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. We have disclosed all significant matters for which we are unable to reasonably estimate a range of possible loss.

Note 4 – Debt and Financing Arrangements

Credit Facility

We, along with Williams and Northwest Pipeline LLC (Northwest), are party to a credit agreement with aggregate commitments available of $3.75 billion, with up to an additional $500 million increase in aggregate commitments available under certain circumstances. We and Northwest are each able to borrow up to $500 million under the credit facility to the extent not otherwise utilized by the other co-borrowers. At June 30, 2022, 0 letters of credit have been issued and 0 loans were outstanding under the credit facility.

Notes (Continued)

Credit Facility

In October 2021, we, along with Williams and Northwest Pipeline LLC (Northwest), the lenders named therein, and an administrative agent entered into an amended and restated credit agreement (Credit Agreement) that reduced aggregate commitments available from $4.5 billion to $3.75 billion, with up to an additional $500 million increase in aggregate commitments available under certain circumstances. The Credit Agreement was effective on October 8, 2021. The maturity date of the credit facility is October 8, 2026. However, the co-borrowers may request up to two extensions of the maturity date each for an additional one-year period to allow a maturity date as late as October 8, 2028, under certain circumstances. The Credit Agreement allows for swing line loans up to an aggregate of $200 million, subject to available capacity under the credit facility, and letters of credit commitments of $500 million. We and Northwest are each able to borrow up to $500 million under this credit facility to the extent not otherwise utilized by the other co-borrowers. At September 30, 2021, and as of October 8, 2021, the effective date of the amended and restated Credit Agreement, 0 letters of credit have been issued and 0 loans were outstanding under the credit facility.

The Credit Agreement contains the following terms and conditions:

Various covenants may limit, among other things, a borrower’s and its material subsidiaries’ ability to grant certain liens supporting indebtedness, merge or consolidate, sell all or substantially all of its assets in certain circumstances, make certain distributions during an event of default, and each borrower and each borrower’s respective material subsidiaries’ ability to enter into certain restrictive agreements.

If an event of default with respect to a borrower occurs under the credit facility, the lenders will be able to terminate the commitments for the respective borrowers and accelerate the maturity of the loans of the defaulting borrower under the credit facility and exercise other rights and remedies.

Other than swing line loans, each time funds are borrowed, the applicable borrower may choose from two methods of calculating interest: a fluctuating base rate equal to an alternative base rate as defined in the Credit Agreement plus an applicable margin or a periodic fixed rate equal to the London Interbank Offered Rate (LIBOR) plus an applicable margin. Williams is required to pay a commitment fee based on the unused portion of the credit facility. The applicable margin is determined by reference to a pricing schedule based on the applicable borrower’s senior unsecured long-term debt ratings and the commitment fee is determined by reference to a pricing schedule based on Williams’ senior unsecured long-term debt ratings. The Credit Agreement also includes customary provisions to provide for replacement of LIBOR with an alternative benchmark rate when LIBOR ceases to be available.

The ratio of debt to capitalization (defined as net worth plus debt), each as defined in the Credit Agreement, must be no greater than 65 percent for each of Transco and Northwest Pipeline.

At September 30, 2021, we are in compliance with this covenant.

Fair Value Methods

The following methods and assumptions were used to estimate the fair value of each class of financial instruments for which it is practicable to estimate that value:

ARO Trust investments: We deposit a portion of our collected rates, pursuant to the terms of the Docket No. RP18-1126 rate case settlement, into the ARO Trust, which is specifically designated to fund future asset retirement obligations.AROs. 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 are reported in Other Assets-OtherAssets - Other inon the Condensed Balance Sheet. However, both realized and unrealized gains and losses are ultimately recorded as regulatory assets or liabilities. (SeeSee Note 5 ARO Trust for more information regarding the ARO Trust.)information.

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 value of the financing obligations associated with our Dalton, and Atlantic Sunrise expansions,and Leidy South projects, which are included within long-term debt, were determined using an income approach (See(see Note 4 Debt and Financing Arrangements)Arrangements).

Note 7 – Transactions with Affiliates

We are a participant in Williams’ cash management program, and we make advances to and receive advances from and make advances to Williams. At SeptemberJune 30, 20212022 and December 31, 2020,2021, our advances to Williams totaled approximately $1,448.3 million$2.0 billion and $642.7 million,$1.7 billion, respectively. These advances are represented by demand notes and are classified as Receivables - Advances to affiliate inon the accompanying Condensed Balance Sheet. Advances are stated at the historical carrying amounts. The interest rate on these intercompany demand notes is based upon the daily overnight investment rate paid on Williams’ excess cash at the end of each month. At September 30, 2021, the interest rate was 0.01 percent.

1413


Notes (Continued)

Interest expense and income are recognized when earned and the collectability is reasonably assured. The interest rate on these intercompany demand notes is based upon the daily overnight investment rate paid on Williams’ excess cash at the end of each month, which was 1.21 percent at June 30, 2022. The interest income from these advances was $3.3 million and $3.5 million for the three and six months ended June 30, 2022, respectively, and minimal for the three and six months ended June 30, 2021. Such interest income is included in Other (Income) and Other Expenses - Interest income on the Statement of Net Income.

Included in Operating Revenues inon the accompanying Condensed Statement of Net Income are revenues received from affiliates of $15.4$22.6 million and $20.1$43.7 million for the three and ninesix months ended SeptemberJune 30, 2021,2022, respectively, and $2.8$2.1 million and $8.0$4.7 million for the three and ninesix months ended SeptemberJune 30, 2020,2021, respectively. The rates charged to provide sales and services to affiliates are the same as those that are charged to similarly-situated nonaffiliated customers.

Included in Cost of natural gas sales inon the accompanying Condensed Statement of Net Income are costs of gas purchased from affiliates of $1.4$1.8 million and $5.5$7.2 million for the three and ninesix months ended SeptemberJune 30, 2021,2022, respectively, and $0.8$0.7 million and $3.8$4.1 million for the three and ninesix months ended SeptemberJune 30, 2020,2021, respectively. All gas purchases are made at market or contract prices.

We have no employees. Services necessary to operate our business are provided to us by Williams and certain affiliates of Williams. We reimburse Williams and its affiliates for all direct and indirect expenses incurred or payments made (including salary, bonus, incentive compensation and benefits) in connection with these services. Employees of Williams also provide general, administrative and management services to us, and we are charged for certain administrative expenses incurred by Williams. These charges are either directly identifiable or allocated to our assets. Direct charges are for goods and services provided by Williams at our request. Allocated charges are based on a three-factor formula, which considers revenues; property, plant and equipment; and payroll. In management’s estimation, the allocation methodologies used are reasonable and result in a reasonable allocation to us of our costs of doing business incurred by Williams. In the accompanying Condensed Statement of Net Income, weWe have recorded approximately $82.1$87.4 million and $237.8$167.0 million for the three and ninesix months ended SeptemberJune 30, 2021,2022, respectively, and $68.7$75.7 million and $214.5$154.5 million for the three and ninesix months ended SeptemberJune 30, 2020,2021, respectively, for these service expenses, which are primarily included in Operation and maintenance and Administrative and general expenses.expenses on the Statement of Net Income.

We provide services to certain of our affiliates. We recorded reductions in operating expenses for services provided to and reimbursed by our affiliates of $1.9$2.1 million and $5.4$3.7 million for the three and ninesix months ended SeptemberJune 30, 2021,2022, respectively, and $1.6$1.8 million and $3.8$3.5 million for the three and ninesix months ended SeptemberJune 30, 2020,2021, respectively.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

General

The following discussion should be read in conjunction with the Financial Statements, Notes and Management’s Discussion and Analysis contained in Items 7 and 8 of our 20202021 Annual Report on Form 10-K and with the Condensed Financial Statements and Notes contained in this Form 10-Q.

Results of Operations

Operating IncomeThis analysis discusses financial results of our operations for the six-month periods ended June 30, 2022 and Net Income2021. Variances due to the changes in natural gas prices and transportation volumes have little impact on revenues, because under our rate design methodology, the majority of overall cost of service is recovered through firm capacity reservation charges in our transportation rates.

We have cash out sales, which settle gas imbalances with shippers. In the course of providing transportation services to customers, we may receive different quantities of gas from shippers than the quantities delivered on behalf of those shippers. Additionally, we transport gas on various pipeline systems, which may deliver different quantities of gas on our behalf than the quantities of gas received from us. These transactions result in gas transportation and exchange imbalance receivables and payables. Our tariff includes a method whereby the majority of transportation imbalances are settled on a monthly basis through cash out sales or purchases. The cash out sales have no impact on our operating income.

OperatingDuring the first six months of 2022, we recognized Net Incomeof for the nine months ended September 30, 2021 was $1,015.4$554.0 million compared to $995.3$531.2 million for the same period in 2020. The increase in Operating Income of $20.1 million (2.0 percent) was primarily due to higher Natural gas transportation revenues inrecognized during the first ninesix months of 2021 compared to the same period in 2020, partially offset by an unfavorable change in Operating Costs and Expenses, as2021. The significant components of this year-over-year increase of $22.8 million (4.3 percent) are discussed further below.

Net Income for the nine months ended September 30, 2021 was $791.2 million compared to $779.7 million for the same period in 2020. In addition to the impacts to Operating Income mentioned above, the increase in Net Income of $11.6 million (1.5 percent) was further unfavorably impacted by Other (Income) and Other Expenses, as discussed below.

Operating Revenues

Natural gas salesdecreased $11.6 revenues increased $28.8 million (19.0 percent) for the nine months ended September 30, 2021 compared to the same period in 2020. The decrease was primarily due to lower cash out sales, partially offset by higher prices. Cash out sales are offset in operating costscash-out volumes and expenses and therefore have no impact on our operating income or results of operations.pricing.

Natural gas storage revenuesincreased $6.2$9.5 million (5.2(11.3 percent) for the nine months ended September 30, 2021 compared to the same period in 2020. The increase was primarily due to an increase in rates that became effective induring the second quarter of 2020.2022.

Operating Costs and Expenses,excluding the Cost of natural gas sales, which directly offsets Natural gas sales in Operating Revenues, increased $68.5 million (12.2 percent). This increase was primarily attributable to:

$48.4 million increase in Operation and maintenance costs primarily resulting from (i) increased transportation costs of $20.0 million associated with Leidy South, (ii) higher electric power costs of $13.5 million (electric power costs are recovered from customers through transportation rates and are offset in Operating Revenues resulting in no net impact on our results of operations), (iii) higher storage costs of $8.4 million (offset in Operating Revenues resulting in no net impact on our results of operations) and (iv) higher employee-related labor and benefit costs of $5.9 million;

Management’s Discussion and Analysis (Continued)
Pipeline Expansion Projects

Leidy South

The Leidy South Project involves an expansion of our existing natural gas transmission system and an extension of our system through a capacity lease with National Fuel Gas Supply Corporation that will enable us to provide incremental firm transportation from Clermont, Pennsylvania and from the Zick interconnection on Transco’s Leidy Line to the River Road regulating station in Lancaster County, Pennsylvania. In July 2020, we received approval from the FERC for the project. We placed 125 Mdth/d of capacity under the project into service in the fourth quarter of 2020, and in September and October of 2021, we placed approximately 382 Mdth/d of additional capacity into service. We plan to place the remainder of Transco’s facilities under the project into service by year-end 2021. The project is expected to increase capacity by 582 Mdth/d.

Regional Energy Access

The Regional Energy Access Expansion involves an expansion of our existing natural gas transmission system to provide incremental firm transportation capacity from receipt points in northeastern Pennsylvania to multiple delivery points in Pennsylvania, New Jersey, and Maryland. We filed our certificate application for the project with the FERC on March 26, 2021. We plan to place the project into service as early as the fourth quarter of 2023,2024, assuming timely receipt of all necessary regulatory approvals. The project is expected to increase capacity by 829 Mdth/d.

Southside Reliability Enhancement

The Southside Reliability Enhancement Project is an incremental expansion of our existing natural gas transmission system to provide firm transportation capacity from receipt points in Virginia and North Carolina to delivery points in North Carolina. The expansion project will add a total of approximately 423 Mdth/d of capacity. We plan to place the project into service as early as the 2024/2025 winter heating season assuming timely receipt of all necessary regulatory approvals. We filed our certificate application for the project with the FERC on May 23, 2022.

Item 4. Controls and Procedures

Disclosure Controls and Procedures

Our management, including our Senior Vice President and our Vice President and Chief Accounting Officer, does not expect that our disclosure controls and procedures (as defined in Rules 13a-15(e)13a - 15(e) and 15d-15(e)15d - 15(e) of the Securities Exchange Act, of 1934, as amended) (Disclosure Controls) or our internal control over financial reporting (Internal Controls) will prevent all errors and all fraud. A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within the company have been detected. These inherent limitations include the realities that judgments in decision-making can be faulty, and that breakdowns can occur because of simple error or mistake. Additionally, controls can be circumvented by the individual acts of some persons, by collusion of two or more people, or by management override of the control. The design of any system of controls also is based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions. Because of the inherent limitations in a cost-effective control system, misstatements due to error or fraud may occur and not be detected. We monitor our Disclosure Controls and Internal Controls and make modifications as necessary; our intent in this regard is that the Disclosure Controls and Internal Controls will be modified as systems change and conditions warrant.

Evaluation of Disclosure Controls and Procedures

An evaluation of the effectiveness of the design and operation of our Disclosure Controls was performed as of the end of the period covered by this report. This evaluation was performed under the supervision and with the participation of our management, including our Senior Vice President and our Vice President and Chief Accounting Officer. Based upon that evaluation, our Senior Vice President and our Vice President and Chief Accounting Officer concluded that these Disclosure Controls are effective at a reasonable assurance level.

Changes in Internal Control Overover Financial Reporting

On July 1, 2021, our parent implemented a new enterprise resource planning (ERP) system on a company-wide basis. We will continue to evaluate and test control changes in order to provide certification on the effectiveness, in all material respects, of our internal controls over financial reporting for the year ending December 31, 2021.

Other than as set forth above, thereThere have been no changes during the thirdsecond quarter of 20212022 that have materially affected, or are reasonably likely to materially affect, our Internal Control over Financial Reporting.
PART II — OTHER INFORMATION.

Item 1. Legal Proceedings

Environmental
