CEO Perspective

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

“Our 8 percent higher Adjusted EBITDA was driven by the continued outperformance of our transmission, storage and gathering businesses, which delivered 13 percent higher Adjusted EBITDA compared to the same period last year. Contracted transmission capacity achieved another record in the first quarter and our Transco projects recently placed into service contributed additional fee-based revenues, as did our immediately accretive acquisitions, including the Gulf Coast storage portfolio that we closed in the quarter."

“Crisp execution by our teams in both integrating newly acquired assets and building large-scale organic projects has us on track to be in the top half of our original 2024 guidance range. As our natural gas-focused strategy continues to gain momentum, we are successfully executing a full slate of high return growth projects, with new regulatory milestones reached on seven of our FERC-regulated expansion projects so far this year and progressing on a healthy backlog of expansion opportunities to serve accelerating demand for natural gas.

Armstrong added, “Our track record of generating predictable, growing earnings in all market cycles underscores the value of Williams as a resilient, long-term investment with a strong dividend. We’ve built a business positioned for the future, and we’re leveraging our existing infrastructure and project development capabilities to serve rising domestic and global security needs, while lowering emissions and creating sustainable value for our shareholders.”

GAAP Measures

First-quarter 2024 net income decreased by $295 million compared to the prior year reflecting an unfavorable change of $419 million in net unrealized gains/losses on commodity derivatives, higher net interest expense from recent debt issuances and retirements, as well as higher operating costs, depreciation and interest expense resulting from recent acquisitions. These unfavorable changes were

2

partially offset by a $211 million increase in service revenues driven by acquisitions and expansion projects. The tax provision decreased primarily due to lower pretax income.

First-quarter 2024 cash flow from operations decreased compared to the prior year primarily due to unfavorable net changes in both working capital and derivative collateral requirements.

Non-GAAP Measures

First-quarter 2024 Adjusted EBITDA increased by $139 million over the prior year, driven by the previously described favorable net contributions from acquisitions and expansion projects.

First-quarter 2024 Adjusted Net Income improved by $35 million over the prior year, driven by the previously described impacts to net income, adjusted primarily to remove the effects of net unrealized gains/losses on commodity derivatives and the related income tax effects.

First-quarter Available Funds From Operations (AFFO) increased by $62 million compared to the prior year primarily due to the change in operating results exclusive of non-cash items.

Business Segment Results & Form 10-Q

Williams' operations are comprised of the following reportable segments: Transmission & Gulf of Mexico, Northeast G&P, West and Gas & NGL Marketing Services, as well as Other. For more information, see the company's first-quarter 2024 Form 10-Q.

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

First-quarter 2024 Modified and Adjusted EBITDA improved compared to the prior year driven by favorable net contributions from the Gulf Coast Storage and MountainWest acquisitions and the Regional Energy Access expansion project. Modified EBITDA for both periods was impacted by one-time acquisition costs, which are excluded from Adjusted EBITDA.

Northeast G&P

First-quarter 2024 Modified and Adjusted EBITDA increased over the prior year driven by higher rates and volumes at Susquehanna Supply Hub, higher rates at Cardinal, and higher contribution from our Aux Sable investment, partially offset by lower volumes at Ohio Valley Midstream.

West

First-quarter 2024 Modified and Adjusted EBITDA increased compared to the prior year benefiting from the DJ Basin Acquisitions and improved commodity margins reflecting favorable changes in shrink prices related to the absence of a short-term gas price spike at Opal in 2023, partially offset by lower realized gains on natural gas hedges. Modified EBITDA was also impacted by the absence of a 2023 favorable contract settlement, which is excluded from Adjusted EBITDA.

Gas & NGL Marketing Services

First-quarter 2024 Modified EBITDA decreased from the prior year primarily reflecting lower commodity marketing margins and a $427 million net unfavorable change in unrealized gains/losses on commodity derivatives, which is excluded from Adjusted EBITDA.

2024 Financial Guidance

After our strong first-quarter performance, Williams expects Adjusted EBITDA at the top half of its 2024 guidance range of $6.8 billion and $7.1 billion. The company continues to expect 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 for emissions reduction and modernization initiatives. For 2025, the company continues to expect 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 continues to anticipate 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, 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 net income (loss) excluding the effect of certain noncash items, reduced by distributions from equity-method investees, net distributions to noncontrolling interests, and preferred dividends. AFFO may also 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.
