CEO Perspective

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

"Strong demand for natural gas and the resiliency of our well-positioned business are clearly reflected in our second-quarter 2019 results. Compared to second-quarter 2018, our Cash Flow From Operations increased by 20% and Adjusted Income Per Share rose by 53%. Low gas prices will continue to incentivize demand growth, and demand for low cost power generation, LNG exports and new industrial loads will grow even faster in the second half of the year. So we expect this predictable cash flow growth to continue.

"We expect to maintain the momentum we've achieved in deleveraging as we continue our intense focus on the efficiency of our operations and lowering our costs. This disciplined approach ensures we deliver the most competitive cost structure in our space for our shareholders. We now see our 2019 leverage coming in better than

1

expected at less than 4.5x versus our original guidance of less than 4.75x. That's a tribute to crisp execution in operations, growth projects and value-adding transactions."

Armstrong added, "This quarter also saw the delivery of our 2018 Sustainability Report. We recognize the important role natural gas plays in helping to address environmental concerns about air quality and climate change, while providing lower utility bills to consumers and industry. As our actions demonstrate, Williams is eager to do its part to help our country meet its climate goals with low carbon natural gas solutions that are ready now and keep jobs and industry here at home."

GAAP Measures

• Second-quarter 2019 Net Income benefited from increased service revenues in the Atlantic-Gulf segment primarily from Transco expansion projects and in the Northeast G&P segment driven by growth in gathering volumes, partially offset by a decline in the West segment results due to lower commodity margins and the absence of the former Four Corners area business sold in fourth-quarter 2018. The current year benefited from a $122 million gain on the sale of our 50 percent interest in Jackalope, partially offset by the absence of a $62 million gain in the prior year associated with the deconsolidation of that Jackalope interest. Asset impairments in the current year were substantially offset by similar levels of impairments in the prior year. Second-quarter 2019 also includes $43 million of estimated employee severance and related costs. The estimated severance costs are primarily associated with a voluntary separation program announced in anticipation of our pending organizational realignment and considering our ongoing evaluation of cost structure. The current year also reflects higher interest expense associated with financing obligations for leased pipeline capacity and higher provision for income taxes driven by higher pre-tax income. Net Income also reflects less income attributable to noncontrolling interests driven by the WPZ merger in the third-quarter 2018.

• Year-to-date 2019 Net Income benefited from increased service revenues in the Atlantic-Gulf segment primarily from Transco expansion projects and in the Northeast G&P segment driven by growth in volumes, partially offset by a decline in West segment results due to lower commodity margins and the

2

absence of the former Four Corners area business. Other drivers of the improvement are similar to those described for the second-quarter results, partially offset by a $74 million first-quarter 2019 impairment of an equity-method investment.

• The increase in Cash Flow From Operations for second-quarter and year-to-date 2019 periods was largely driven by the increased service revenues in the Atlantic-Gulf and Northeast G&P segments, the collection of Transco's filed rates subject to refund, and the receipt of an income tax refund, partially offset by the decline in West segment results.

Non-GAAP Measures

• The increase in Adjusted EBITDA for second-quarter 2019 and year-to-date 2019 largely reflects the previously mentioned increased service revenues in the Atlantic-Gulf and Northeast G&P segments, partially offset by the decline in West segment results.

• Adjusted Income for both the quarter and year-to-date periods also improved, driven by the higher Adjusted EBITDA and less income attributable to noncontrolling interests, partially offset by higher interest expense and provision for income taxes.

• Second-quarter and year-to-date 2019 DCF are higher, reflecting the increased Adjusted EBITDA, an income tax refund received in 2019, and lower maintenance capital, partially offset by higher net interest expense.

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.

Atlantic-Gulf

• Improvement in second-quarter and year-to-date 2019 Modified and Adjusted EBITDA is driven by Transco expansion projects, including Atlantic Sunrise (in service October 2018) and Gulf Connector (in service early January 2019).

• Unfavorable impact from a reduced allowance for equity funds used during construction due to lower levels of construction activity.

• Modified EBITDA was further impacted by the absence of a net favorable regulatory adjustment resulting from Tax Reform in the prior year, along with current-year charges for estimated employee severance and related costs and the reversal of expenditures capitalized in prior years, all of which are excluded from Adjusted EBITDA.

West

• Lower second-quarter and year-to-date 2019 Modified and Adjusted EBITDA reflect lower NGL margins (excluding Four Corners) driven by lower NGL prices.

• Additionally, both second-quarter and year-to-date results reflect the absence of EBITDA from our former Four Corners area business.

• Modified EBITDA for both the quarter and year-to-date 2019 periods includes asset impairment charges and estimated employee severance and related costs that are excluded from Adjusted EBITDA.

• Completed sale of our 50% interest in Jackalope (an equity-method investment) for $485 million in second-quarter 2019.

• Placed into service Ft. Lupton III processing plant expansion of 200 MMcf/d.

3

Northeast G&P

• Improvement in Modified and Adjusted EBITDA for second-quarter and year-to-date 2019 driven by increased gathering volumes in the Susquehanna Supply Hub and in the Utica Shale region and higher proportional EBITDA from investments in the Marcellus South and Bradford gas gathering systems. Modified EBITDA also includes estimated employee severance and related costs that are excluded from Adjusted EBITDA.

• Gross gathering volumes, including 100% of operated equity-method investments, reflect a 17% increase for second-quarter 2019 over second-quarter 2018. Year-to-date, gross gathering volumes increased 16% over the same reporting period in 2018.

• The consolidation of Utica East Ohio Midstream ("UEO") following our March 2019 purchase of the remaining 38% ownership stake in UEO favorably impacted both Modified and Adjusted EBITDA, driving an $11 million increase for second-quarter 2019 over second-quarter 2018. Year-to-date results reflect a $13 million favorable impact over the same reporting period in 2018 due to the consolidation of UEO.

• Successfully completed the formation of the new Northeast JV with CPPIB in June 2019, receiving approximately $1.33 billion from CPPIB for its 35% interest in the venture.

Non-GAAP Measures

This news release and accompanying materials may include certain financial measures – Adjusted EBITDA, adjusted income (“earnings”), adjusted earnings per share, distributable cash flow 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. Management believes this measure provides investors meaningful insight into results from ongoing operations.

Distributable cash flow is defined as Adjusted EBITDA less maintenance capital expenditures, cash portion of net interest expense, income attributable to or dividends/ distributions paid to noncontrolling interests and cash income taxes, and certain other adjustments that management believes affects the comparability of results. Adjustments for maintenance capital expenditures and cash portion of interest expense include our proportionate share of these items of our equity-method investments. We also calculate the ratio of distributable cash flow to the total cash dividends paid (dividend coverage ratio). This measure reflects Williams’ distributable cash flow relative to its actual cash dividends paid.

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 distributable cash flow 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.

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, outcome 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 herein 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 and natural gas liquids 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 herein. 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:

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

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

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

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

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

• 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 to consummate asset sales on acceptable terms;

• Development and rate of adoption of alternative energy sources;

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

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

• 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;

• Changes in the current geopolitical situation;

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

• 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;

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

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

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

• 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

18

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 herein. 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 filed with the SEC on February 21, 2019.
