CEO Perspective

Alan Armstrong, president and chief executive officer, made the following comments:

“Our natural gas-focused strategy delivered excellent financial results again in 2023 with contracted transmission capacity, gathering volumes and Adjusted EBITDA surpassing previous highs, demonstrating our ability to grow despite low natural gas prices. We expect this strong performance to continue in 2024 and have set our Adjusted EBITDA guidance midpoint at $6.95 billion, paving the way for what we anticipate will be a breakout year in 2025 as several large fee-based projects come online.

"In addition to outstanding financial results in 2023, we acquired strategic natural gas transmission, gathering and storage assets in the Rockies and on the Gulf Coast, enhancing our footprint in key areas and adding highly contracted take-or-pay transmission and fee-based storage assets to our business. We also continue to expand our existing infrastructure with 18 high-return projects in execution, including approximately 3.1 Bcf/d of expansions on Transco coming online over the next few years. I’m extremely proud of our teams for their commitment to best-in-class project execution in what has become a complex and challenging permitting environment for energy infrastructure of all types."

Armstrong added, “Looking ahead, Williams is excited to provide additional natural gas solutions to support the reliability of the U.S. power sector as it faces growing regional demand driven in large part by the emergence of new, large-scale data centers that are accelerating throughout our key markets. With the buildout of electrification and renewables, as well as previously permitted LNG export growth, Williams will be there to provide additional natural gas baseload to ensure reliability. Our infrastructure today is vital to meeting the energy needs of tomorrow. Natural gas is an immediate and scalable climate solution to reduce global emissions and serve the growing need for energy security, while creating long-term value for our shareholders.”

GAAP Measures

Fourth-quarter 2023 net income increased by $478 million compared to the prior year driven by a $534 million gain related to the net cash received from the favorable resolution of litigation with Energy Transfer. The improvement also reflects a favorable change of $147 million in net unrealized gains/losses on commodity derivatives and higher service revenues driven by recent acquisitions and expansion projects. These improvements were partially offset by lower gas marketing margins reflecting the absence of favorable severe winter weather impacts in the prior year, lower results from our upstream business, and higher depreciation and operating expenses resulting from acquisitions. The income tax provision increased $114 million primarily due to higher pretax income.

Full-year 2023 net income increased $1.2 billion compared to the prior year reflecting a favorable change of $909 million in net unrealized gains/losses on commodity derivatives, the previously described $534 million net litigation gain, and higher service revenues driven by recent acquisitions, expansion projects, and increased Northeast G&P volumes and rates. The improvement also included a $129 million gain on the sale of the Bayou Ethane system in 2023, partially offset by lower results from our upstream business, and higher depreciation and operating expenses resulting from acquisitions. The income tax provision increased $580 million primarily due to higher pretax income and the absence of $134 million benefit associated with the release of valuation allowances on deferred income tax assets and federal income tax settlements recorded in the prior year, and a lower benefit associated with decreases in our estimate of the state deferred income tax rate in both periods. The 2023 period also reported a loss from discontinued operations associated with an adverse legal ruling involving former refinery operations.

Cash flow from operations for the fourth quarter increased compared to the prior year primarily due to $534 million of net cash received related to the favorable Energy Transfer litigation outcome and favorable net changes in working capital. Full-year cash flow from operations increased compared to the prior year reflecting similar drivers, as well as favorable changes in derivative margin requirements partially offset by lower distributions from certain equity-method investments.

Non-GAAP Measures

Fourth-quarter 2023 Adjusted EBITDA decreased by $53 million from the prior year, driven by the previously described higher service revenues, more than offset by lower gas marketing margins, reduced upstream results and higher operating costs. Full-year 2023 Adjusted EBITDA increased by $361 million over the prior year, driven by the previously described higher service revenues, partially offset by reduced upstream results and higher operating costs.

Fourth-quarter 2023 Adjusted Net Income decreased by $65 million compared to the prior year, driven by the previously described impacts to net income, adjusted primarily to remove the net litigation gain, net unrealized gains/losses on commodity derivatives, and the related tax effects of these adjustments. Full-year Adjusted Net Income increased by $106 million over the prior year driven by the previously described impacts to net income from continuing operations, adjusted primarily for the litigation gain, net unrealized gains/losses on commodity derivatives, the gain on the sale of the Bayou Ethane system, amortization of certain assets from the Sequent acquisition, and the related tax effects of these adjustments as well as excluding the impact of the previously described prior year favorable income tax benefits.

Fourth-quarter 2023 Available Funds From Operations (AFFO) decreased slightly by $34 million compared to the prior year primarily due to lower operating results exclusive of noncash items. Full-year 2023 AFFO increased by $295 million primarily reflecting higher results from continuing operations exclusive of non-cash items partially offset by lower distributions from certain equity method investments.

Note: Williams uses Modified EBITDA for its segment reporting. Definitions of Modified EBITDA and Adjusted EBITDA and schedules reconciling to net income are included in this news release.

Transmission & Gulf of Mexico

Fourth-quarter 2023 Modified and Adjusted EBITDA improved compared to the prior year driven by the MountainWest acquisition. Modified EBITDA for full-year 2023 was further impacted by the gain on the sale of the Bayou Ethane system, benefits from the NorTex acquisition and expansion projects, increased benefit of allowance for equity funds used during construction, and one-time MountainWest acquisition and transition costs, while 2022 included a loss related to Eminence storage cavern abandonments and a regulatory charge associated with Transco’s deferred state income tax rate. The gain on sale, MountainWest acquisition and transition costs, Eminence abandonment costs, and Transco’s regulatory charge are all excluded from Adjusted EBITDA.

Northeast G&P

Fourth-quarter and full-year 2023 Modified and Adjusted EBITDA improved reflecting increased rates and volumes driven by the Ohio Valley, Cardinal, and Susquehanna operations. For our joint ventures, the full-year benefits of higher volumes and rates at Marcellus South and higher volumes at Blue Racer were more than offset by lower rates and volumes at Laurel Mountain Midstream and Bradford compared to the prior year. Modified EBITDA for full-year 2023 also reflects our share of a loss contingency accrual at Aux Sable which is excluded from Adjusted EBITDA.

West

Fourth-quarter 2023 Modified and Adjusted EBITDA decreased compared to the prior year primarily reflecting lower NYMEX-based rates in the Barnett partially offset by benefits from the DJ Basin Acquisitions. Full-year Modified and Adjusted EBITDA improved compared to the prior year driven by benefits from the DJ Basin and Trace Midstream Acquisitions and higher volumes at our Overland Pass joint venture. Favorable changes in operating and administrative costs were more than offset by lower processing margins reflecting a short-term gas price spike at Opal early in the year and severe weather impacts and lower service revenues reflecting lower NYMEX-based rates in the Barnett partially offset by favorable changes in realized gains on natural gas hedges and higher Haynesville volumes.

Gas & NGL Marketing Services

Fourth-quarter 2023 Modified EBITDA improved from the prior year primarily reflecting a $142 million net favorable change in unrealized gains/losses on commodity derivatives partially offset by lower gas marketing margins reflecting the absence of favorable severe winter weather impacts in the prior year. Full-year 2023 Modified EBITDA improved from the prior year primarily reflecting a $933 million net favorable change in unrealized gains/losses on commodity derivatives and higher commodity marketing margins reflecting reduced levels of inventory write-downs partially offset by the previously discussed lower gas marketing margins. The unrealized gains/losses on commodity derivatives are excluded from Adjusted EBITDA.

Other

4

Fourth-quarter and full-year 2023 Modified EBITDA increased compared to the prior year primarily reflecting the $534 million gain from the net cash received from the favorable resolution of our litigation with Energy Transfer, partially offset by lower results from our upstream business driven by lower prices, partially offset by higher production volumes. The full-year comparison also reflects a $24 million unfavorable change in unrealized gains/losses on commodity derivatives. Adjusted EBITDA for both comparative periods was lower and excludes the favorable litigation gain and the effects of changes in unrealized gains/losses on commodity derivatives.

Financial Guidance

The company expects 2024 Adjusted EBITDA between $6.8 billion and $7.1 billion. The company also expects 2024 growth capex between $1.45 billion and $1.75 billion and maintenance capex between $1.1 billion and $1.3 billion, which includes capital of $350 million based on midpoint for emissions reduction and modernization initiatives. For 2025, the company expects Adjusted EBITDA between $7.2 billion and $7.6 billion with growth capex between $1.65 billion and $1.95 billion and maintenance capex between $750 million and $850 million, which includes capital of $100 million based on midpoint for emissions reduction and modernization initiatives. Williams anticipates a leverage ratio midpoint for 2024 of 3.85x and has increased the dividend by 6.1% on an annualized basis to $1.90 in 2024 from $1.79 in 2023.

Non-GAAP Measures

This news release and accompanying materials may include certain financial measures – adjusted EBITDA, adjusted income (“earnings”), adjusted earnings per share, available funds from operations and dividend coverage ratio – that are non-GAAP financial measures as defined under the rules of the SEC.

Our segment performance measure, modified EBITDA, is defined as net income (loss) before income (loss) from discontinued operations, income tax expense, net interest expense, equity earnings from equity-method investments, other net investing income, impairments of equity investments and goodwill, depreciation and amortization expense, and accretion expense associated with asset retirement obligations for nonregulated operations. We also add our proportional ownership share (based on ownership interest) of modified EBITDA of equity-method investments.

Adjusted EBITDA further excludes items of income or loss that we characterize as unrepresentative of our ongoing operations. Such items are excluded from net income to determine adjusted income and adjusted earnings per share. Management believes this measure provides investors meaningful insight into results from ongoing operations.

Available funds from operations (AFFO) is defined as cash flow from operations excluding the effect of changes in working capital and certain other changes in noncurrent assets and liabilities, reduced by preferred dividends and net distributions to noncontrolling interests. AFFO may be adjusted to exclude certain items that we characterize as unrepresentative of our ongoing operations.

This news release is accompanied by a reconciliation of these non-GAAP financial measures to their nearest GAAP financial measures. Management uses these financial measures because they are accepted financial indicators used by investors to compare company performance. In addition, management believes that these measures provide investors an enhanced perspective of the operating performance of assets and the cash that the business is generating.

Neither adjusted EBITDA, adjusted income, nor available funds from operations are intended to represent cash flows for the period, nor are they presented as an alternative to net income or cash flow from operations. They should not be considered in isolation or as substitutes for a measure of performance prepared in accordance with United States generally accepted accounting principles.

(1) The sum of earnings per share for the quarters may not equal the total earnings per share for the year due to changes in the weighted-average number of common shares outstanding.
(2) The second quarter of 2022 includes adjustments for the reversal of valuation allowance due to the expected utilization of certain deferred income tax assets and previously unrecognized tax benefits from the resolution of certain federal income tax audits. The third quarter of 2022 includes an unfavorable adjustment to reverse the net benefit primarily associated with a significant decrease in our estimated deferred state income tax rate, partially offset by an unfavorable revision to a state net operating loss carryforward. The third quarter of 2023 includes an adjustment associated with a further decrease in our estimated deferred state income tax rate.

Forward-Looking Statements

The reports, filings, and other public announcements of The Williams Companies, Inc. (Williams) may contain or incorporate by reference statements that do not directly or exclusively relate to historical facts. 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, outcomes of regulatory proceedings, market conditions, and other matters. We make these forward-looking statements in reliance on the safe harbor protections provided under the Private Securities Litigation Reform Act of 1995.

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. These forward-looking statements are based on management’s beliefs and assumptions and on information currently available to management and include, among others, statements regarding:

•Levels of dividends to Williams stockholders;

•Future credit ratings of Williams and its affiliates;

•Amounts and nature of future capital expenditures;

•Expansion and growth of our business and operations;

•Expected in-service dates for capital projects;

•Financial condition and liquidity;

•Business strategy;

•Cash flow from operations or results of operations;

•Seasonality of certain business components;

•Natural gas, natural gas liquids, and crude oil prices, supply, and demand;

•Demand for our services.

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:

20

•Availability of supplies, market demand, and volatility of prices;

•Development and rate of adoption of alternative energy sources;

•The impact of existing and future laws and regulations, the regulatory environment, environmental matters, and litigation, as well as our ability and the ability of other energy companies, with whom we conduct or seek to conduct business, to obtain necessary permits and approvals, and our ability to achieve favorable rate proceeding outcomes;

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

•Our ability to acquire new businesses and assets and successfully integrate those operations and assets into existing businesses as well as successfully expand our facilities, and consummate asset sales on acceptable terms;

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

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

•The amount of cash distributions from and capital requirements of our investments and joint ventures in which we participate;

•Whether we will be able to effectively execute our financing plan;

•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;

•The impacts of operational and developmental hazards and unforeseen interruptions;

•The risks resulting from outbreaks or other public health crises;

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

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

•Our costs and funding obligations for defined benefit pension plans and other postretirement benefit plans;

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

•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);

•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;

21

•The ability of the members of the Organization of Petroleum Exporting Countries and other oil exporting nations to agree to and maintain oil price and production controls and the impact on domestic production;

•Changes in the current geopolitical situation, including the Russian invasion of Ukraine and conflicts in the Middle East including between Israel and Hamas and conflicts involving Iran and its proxy forces;

•Changes in U.S. governmental administration and policies;

•Whether we are able to pay current and expected levels of dividends;

•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 (a) Part I, Item 1A. Risk Factors in our Annual Report on Form 10-K for the year ended December 31, 2022, as filed with the SEC on February 27, 2023, (b) Part II, Item 1A. Risk Factors in subsequent Quarterly Reports on Form 10-Q, and (c) when filed with the SEC, Part I, Item 1A. Risk Factors in our Annual Report on Form 10-K for the year ended December 31, 2023.
