All other content on this page is deterministically > extracted from the original SEC filing. > Williams Companies' 2026 10-K Risk Factors filing shows 2 risk factor sections from 2025 with no close textual match in 2026, specifically addressing pipeline opposition and FERC regulatory constraints on rate recovery. The 2026 filing contains 38 substantially similar matched sections and 4 matched sections with meaningful text differences compared to 2025, with no new risk factor sections appearing in 2026 that lack a textual match in 2025. --- ## Summary | Status | Count | |--------|-------| | New risks added | 0 | | Risks removed | 2 | | Risks modified | 4 | | Unchanged | 38 | --- ## No Match in Current: Williams, Transco, and NWP face opposition to the operation and expansion of pipelines and facilities from various individuals and groups. *This section from the 2025 filing does not have a high-confidence textual match in 2026. It may have been removed, merged, or substantially reworded.* Williams, Transco, and NWP have experienced, and anticipate continuing to face, opposition to the operation and expansion of pipelines and facilities from governmental officials, environmental groups, landowners, tribal groups, local groups, and other advocates. In some instances, Williams, Transco, and NWP encounter opposition that disfavors hydrocarbon-based energy supplies regardless of practical implementation or financial considerations. Opposition to operation and expansion can take many forms, including the delay or denial of required governmental permits, organized protests, attempts to block or sabotage operations, intervention in regulatory or administrative proceedings involving assets, or lawsuits or other actions designed to prevent, disrupt, or delay the operation or expansion of assets and business. In addition, acts of sabotage or eco-terrorism could cause significant damage or injury to people, property, or the environment or lead to extended interruptions of operations. Any such event that delays or prevents the expansion of Williams', Transco's, or NWP's businesses, that interrupts the revenues generated by operations, or that causes significant expenditures not covered by insurance, could adversely affect Williams', Transco's, and NWP's financial condition and results of operations. --- ## No Match in Current: The natural gas sales, transportation, and storage operations of Williams', Transco's, and NWP's natural gas pipelines are subject to regulation by the FERC, which could have an adverse impact on their ability to establish transportation and storage rates that would allow them to recover the full cost of operating their respective pipelines and storage assets, including a reasonable rate of return. *This section from the 2025 filing does not have a high-confidence textual match in 2026. It may have been removed, merged, or substantially reworded.* In addition to regulation by other federal, state, and local regulatory authorities, interstate pipeline transportation and storage services and related assets are subject to regulation by the FERC. Federal regulation extends to such matters as: •Transportation and sale for resale of natural gas in interstate commerce; •Rates, operating terms, types of services, and conditions of service; •Certification and construction of new interstate pipelines and storage facilities; •Acquisition, extension, disposition, or abandonment of existing interstate pipelines and storage facilities; •Accounts and records; •Depreciation and amortization policies; •Relationships with affiliated companies that are involved in marketing functions of the natural gas business; •Market manipulation in connection with interstate sales, purchases, or transportation of natural gas. Regulatory or administrative actions in these areas, including successful complaints or protests against the rates of the gas pipelines, can affect Williams', Transco's, and NWP's businesses in many ways, including decreasing tariff rates and revenues or setting future tariff rates to levels such that revenues are inadequate to recover increases in operating costs or to sustain an adequate return on capital investments, decreasing volumes in the pipelines, increasing costs, and otherwise altering the profitability of the pipeline business. Furthermore, Transco charges its transportation customers a separate fee to access its offshore facilities in the Gulf of America, unlike other interstate pipelines that own facilities offshore. The separate charge is referred to as an "IT feeder" charge. The "IT feeder" rate is charged only when gas is actually transported on the applicable facilities and typically it is paid by producers or marketers. Because the "IT feeder" rate is typically paid by producers and marketers, it generally results in netback prices to producers that are slightly lower than the netbacks realized by producers transporting on other interstate pipelines. This rate design disparity can result in producers bypassing Transco's offshore facilities in favor of alternative transportation facilities. --- ## Modified: Certain of Williams', Transco's, and NWP's natural gas pipeline services are subject to long-term, fixed-price contracts that are not subject to adjustment, even if the cost to perform such services exceeds the revenues received from such contracts. **Key changes:** - Reworded sentence: "Regulatory or administrative actions in these areas, including successful complaints or protests against the rates of the gas pipelines, can affect Williams', Transco's, and NWP's businesses in many ways, including decreasing tariff rates and revenues or setting future tariff rates to levels such that revenues are inadequate to recover increases in operating costs or to sustain an adequate return on capital investments, decreasing volumes in the pipelines, increasing costs, and otherwise altering the profitability of the pipeline business." - Added sentence: "Furthermore, Transco charges its transportation customers a separate fee to access its offshore facilities in the Gulf of America, unlike other interstate pipelines that own facilities offshore." - Added sentence: "The separate charge is referred to as an "IT feeder" charge." - Added sentence: "The "IT feeder" rate is charged only when gas is actually transported on the applicable facilities and typically it is paid by producers or marketers." - Added sentence: "Because the "IT feeder" rate is typically paid by producers and marketers, it generally results in netback prices to producers that are slightly lower than the netbacks realized by producers transporting on other interstate pipelines." **Prior (2025):** Williams', Transco's, and NWP's natural gas pipelines provide some services pursuant to long-term, fixed-price contracts. It is possible that costs to perform services under such contracts will exceed the revenues collected. Although other services are priced at cost-based rates that are subject to adjustment in rate cases, under FERC policy, a regulated service provider and a customer may mutually agree to sign a contract for service at a "negotiated rate" that may be above or below the FERC regulated cost-based rate for that service. These "negotiated rate" contracts are not generally subject to adjustment for increased costs that could be produced by inflation or other factors relating to the specific facilities being used to perform the services. Further, the costs of testing, maintaining, or repairing regulated facilities for Williams, Transco, and NWP may exceed Williams', Transco's and NWP's expectations, and the FERC may not allow, or competition in the markets may prevent, recovery of such costs in the rates charged for applicable services at Williams', Transco's, and NWP's regulated pipelines and facilities. Williams, Transco and NWP have experienced and could experience in the future unexpected leaks or ruptures on their regulated natural gas pipeline systems or storage facilities. Either as a preventative measure or in response to a leak or another issue, Williams, Transco and NWP could be required by regulatory authorities to test or undertake modifications to their regulated systems. If the cost of testing, maintaining, or repairing regulated facilities exceeds expectations, and the FERC does not allow recovery, or competition in the markets prevents recovering such costs in the rates charged for Williams', Transco's and NWP's regulated services, such costs could have a material adverse impact on Williams', Transco's and NWP's businesses, financial condition, results of operation, and cash flows. **Current (2026):** Williams', Transco's, and NWP's natural gas pipelines provide some services pursuant to long-term, fixed-price contracts.

Suitable acquisition candidates or assets may not be available on terms and conditions Williams finds acceptable or, where multiple parties are trying to acquire an acquisition candidate or assets, Williams may not be chosen as the acquirer. If Williams is able to acquire a targeted business, Williams may not be able to successfully integrate the acquired businesses and realize anticipated benefits in a timely manner. Additionally, as part of Williams', Transco's, and NWP's growth strategy, Williams, Transco, and NWP engage in significant capital projects and have both a project lifecycle process and an investment evaluation process. These are the processes used to identify, evaluate, and execute on capital projects, and the investment evaluation process is used by Williams' to identify, evaluate, and execute on acquisitions. Williams, Transco, and NWP may not always have sufficient and accurate information to identify and value potential opportunities and risks or the investment evaluation process may be incomplete or flawed. Growth may also be dependent upon the construction of new natural gas gathering, transportation, compression, processing, or treating pipelines and facilities, NGL transportation, or fractionation or storage facilities as well as the expansion of existing facilities. Additional risks associated with construction may include the inability to obtain rights-of-way, skilled labor, equipment, materials, permits, and other required inputs in a timely manner such that projects are completed, on time or at all, and the risk that construction cost overruns, including due to inflation or the imposition of tariffs on foreign-made materials and 34 34 34 goods (including steel and steel pipes) necessary to conduct business, could cause total project costs to exceed budgeted costs. Additional risks associated with growing the business include, among others, that: •Changing circumstances and deviations in variables could negatively impact the investment analysis, including projections of revenues, earnings, and cash flow relating to potential investment targets, resulting in outcomes that are materially different than anticipated; •Williams, Transco, or NWP could be required to contribute additional capital to support acquired businesses or assets, and Williams, Transco, or NWP may assume liabilities that were not disclosed, exceed estimates and for which contractual protections are either unavailable or prove inadequate; •Acquisitions could disrupt ongoing business, distract management, divert financial and operational resources from existing operations, and make it difficult to maintain current business standards, controls, and procedures; •Acquisitions and capital projects may require substantial new capital, including the issuance of debt or equity, and Williams, Transco, or NWP may not be able to access credit or capital markets or obtain acceptable terms. If realized, any of these risks could have an adverse impact on Williams', Transco's, and NWP's financial condition, results of operations, including the possible impairment of assets, or cash flows. **Current (2026):** As part of Williams' growth strategy, Williams considers acquisition opportunities.

If realized, any of these risks could have an adverse impact on Williams', Transco's, and NWP's financial condition, results of operations, including the possible impairment of assets, or cash flows. 34 34 34 Further, Williams has invested in several power innovation projects and continues to evaluate power innovation projects related to data center growth. Additional risks associated with identifying, evaluating, and executing on power innovation projects may include accurately predicting future power needs of data centers due to rapidly changing technology and market dynamics, which could result in underutilized or stranded assets; managing the potential power demand; obtaining or constructing power generation sources, including sourcing turbines and batteries and maintaining other transmission capabilities to meet potential load growth from any data center customer; financing the capital investment needed to build and maintain the necessary infrastructure to support data center development; managing community opposition; managing the possible environmental impact of power innovation projects, and evaluating and complying with evolving regulations related to data center development. Risks associated with construction are similar to those described above for other capital projects, including obtaining long-lead specialized equipment and materials, such that projects are completed, on time or at all, and the risk that construction cost overruns, including due to inflation or the imposition of tariffs on foreign-made materials and goods necessary to conduct business, could cause total project costs to exceed budgeted costs. Williams' behind the meter power generation projects require the constant, reliable production of electricity, which if not met, may result in contractual penalties and reputational damage, among other consequences. If realized, any of these risks could have an adverse impact on Williams' financial condition, results of operations, including the possible impairment of assets, or cash flows. --- ## Modified: Williams, Transco, and NWP may face opposition to the operation and expansion of pipelines and facilities from various individuals and groups or face increased scrutiny from various stakeholders with respect to environmental, social and governance practices. **Key changes:** - Reworded sentence: "Williams, Transco, and NWP have experienced, and anticipate continuing to face, opposition to the operation and expansion of pipelines and facilities from governmental officials, environmental groups, landowners, tribal groups, local groups, and other advocates." - Reworded sentence: "Williams, Transco, and NWP adopted certain practices as highlighted in Williams' 2024 Sustainability Report, including with respect to air emissions, biodiversity and land use, climate change, and environmental stewardship." **Prior (2025):** Companies across all industries are facing increasing scrutiny from stakeholders related to their environmental, social and governance ("ESG") practices. Investor advocacy groups, institutional investors, investment funds and other influential investors are also increasingly focused on ESG practices and in recent years have placed increasing importance on the implications and social cost of their investments. Regardless of the industry, investors' increased focus and activism related to ESG (as proponents or opponents) and similar matters may hinder access to capital, as investors may decide to reallocate capital or to not commit capital as a result of their assessment of a company's ESG practices. Companies that do not adapt to or comply with investor or other stakeholder expectations and standards, which are evolving, or that are perceived to have not responded appropriately to the concern for ESG issues, regardless of whether there is a legal requirement to do so, may suffer from reputational damage, and the business, financial condition, and/or stock price of such a company could be materially and adversely affected. Williams, Transco, and NWP face pressures from their stakeholders, who are increasingly focused on climate change, to prioritize sustainable energy practices, reduce carbon footprint, and promote sustainability. Williams' stockholders may require Williams to implement ESG procedures or standards to continue engaging with Williams, to remain invested in Williams, or before they may make further investments in Williams. Additionally, Williams, Transco, and NWP may face reputational challenges in the event their ESG procedures or standards do not meet the standards set by certain constituencies. Williams, Transco, and NWP adopted certain practices as highlighted in Williams' 2023 Sustainability Report, including with respect to air emissions, biodiversity and land use, climate 38 38 38 change, and environmental stewardship. It is possible, however, that Williams', Transco's, and NWP's stakeholders might not be satisfied with these sustainability efforts or the speed of their adoption. If Williams, Transco and NWP do not meet stakeholders' expectations, Williams', Transco's, and NWP's businesses, ability to access capital, and/or Williams' stock price could be harmed. Additionally, adverse effects upon the oil and gas industry related to the worldwide social and political environments, including uncertainty or instability resulting from climate change, changes in political leadership and environmental policies, changes in geopolitical-social views toward fossil fuels and renewable energy, concern about the environmental impact of climate change, and investors' expectations regarding ESG matters, may also adversely affect demand for Williams', Transco's, and NWP's services. Any long-term material adverse effect on the oil and gas industry could have a significant financial and operational adverse impact on Williams', Transco's, and NWP's businesses. The occurrence of any of the foregoing could have a material adverse effect on the price of Williams' stock and Williams', Transco's, and NWP's businesses and financial condition. **Current (2026):** Williams, Transco, and NWP have experienced, and anticipate continuing to face, opposition to the operation and expansion of pipelines and facilities from governmental officials, environmental groups, landowners, tribal groups, local groups, and other advocates.
