Second-Quarter 2018 Financial Results

Williams reported unaudited second-quarter 2018 net income attributable to Williams of $135 million, an increase of $54 million from second-quarter 2017. The favorable change was driven primarily by a $32 million increase in operating income due primarily to an increase in service revenues and NGL margins partially offset by the absence of $25 million of operating income earned in second-quarter 2017 by our former olefins operations. Other Investing Income for the quarter was favorably impacted by a $62 million gain on the deconsolidation of Williams Partners' interests in the Jackalope Gas Gathering System. Partially offsetting the improvements were $66 million

of impairments of certain assets in second-quarter 2018 and a $33 million decrease in equity earnings primarily driven by lower earnings at Discovery Producer Services.

Year to date, Williams reported unaudited net income attributable to Williams of $287 million, an unfavorable change of $167 million over the same period in 2017. The decrease was driven primarily by a $202 million unfavorable change in Other Investing Income due largely to the absence of a $269 million gain in first-quarter 2017 associated with a transaction involving certain joint-venture interests in the Permian Basin and Marcellus Shale, partially offset by a $62 million gain on Williams Partners' interests in the Jackalope Gas Gathering System. The unfavorable change also reflects a $58 million decrease in equity earnings primarily driven by lower earnings at Discovery Producer Services and $66 million of impairments of certain assets in second-quarter 2018. Partially offsetting the decrease was a $93 million improvement in operating income, due primarily to an increase in service revenues and NGL margins overcoming the absence of $57 million of operating income earned in the first half of 2017 by our former olefins operations.

Williams reported second-quarter 2018 Adjusted income per share of $0.17, a 31 percent increase over second-quarter 2017 Adjusted income per share of $0.13. The improvement was driven by the same factors affecting net income attributable to Williams, adjusted primarily for excluding the gain on the deconsolidation of the Jackalope Gas Gathering System and impairments of certain assets. Year-to-date, Adjusted income per share was $0.36, a 33 percent improvement over the first-half 2017 result of $0.27.

Williams reported second-quarter 2018 Adjusted EBITDA of $1.11 billion, a $3 million decrease from second-quarter 2017. The modest change was driven by a $37 million decrease in proportional EBITDA from joint ventures due primarily to less production on the Discovery system, the absence of $23 million Adjusted EBITDA earned in second-quarter 2017 from the NGL & Petchem Services business primarily as a result of the sale of the Geismar olefins facility, and $26 million increased operating & maintenance (O&M) expenses at Williams Partners' businesses primarily due to increased reliability and integrity costs at Transco. Partially offsetting these decreases was a $46 million increase in service revenues, driven primarily by expansion projects brought online by Transco in 2017 and 2018. Second-quarter 2018 service revenues would have increased by $67 million over second-quarter 2017 if revenue-recognition standards adopted in 2018 had been applied to second-quarter 2017 results. Additionally, NGL and Marketing margins improved by $35 million.

Year-to-date, Williams reported Adjusted EBITDA of $2.245 billion, a decrease of $13 million from the same six-month reporting period in 2017. The unfavorable change was driven by the absence of $72 million Adjusted EBITDA earned in 2017 from the NGL & Petchem Services business primarily as a result of the sale of the Geismar olefins facility, a $60 million decrease in proportional EBITDA from joint ventures due primarily to less production on the Discovery system, $38 million increased O&M expenses at Williams Partners' businesses primarily due to increased reliability and integrity costs at Transco, and a $12 million regulatory charge per approved pipeline transportation rates associated with the Tax Reform Act. Partially offsetting these decreases was a $125 million increase in service revenues, driven primarily by expansion projects brought online by Transco in 2017 and 2018. Service revenue would have increased by $165 million over first half of 2017 if revenue-recognition standards adopted in 2018 had been applied to first-half 2017 results. Additionally, NGL and Marketing margins improved by $49 million.

CEO Perspective

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

"Our consistent strategy of connecting growing natural gas demand to growing low-cost gas production delivered results which slightly exceeded our business plan for second quarter, and we look forward to an even stronger second half of the year as the Atlantic Sunrise project nears completion and producer activity on our systems in the Northeast and Wyoming is ramping up. We are also excited about the transactions announced earlier this week. Selling assets in a maturing basin at attractive multiples, and redeploying that capital to higher growth basins enhances our position to capitalize on future growth opportunities and follows our strategy to connect the best supplies to the best markets.

"It is clear that our focus on natural gas volume growth combined with our advantaged infrastructure and the continued confidence in low-price natural gas continues to drive demand for services on our systems. Placing the Transco expansion projects into service in 2017 and 2018 is now delivering exceptional fee-based revenue

growth - a $50 million increase for second-quarter 2018 over second-quarter 2017 for Transco transportation revenues thanks to those expansion projects coming online. Our growth was not limited to Transco as Williams Partners' current business segments posted year-over-year increases in Adjusted EBITDA for the quarter and year-to-date.

"I'm pleased our teams were able to complete so much maintenance work this quarter, especially in our high-growth areas where we accelerated inspections and other key maintenance needs into this quarter to take advantage of the timing of outages associated with expansion construction work and project work - particularly important in association with a project like Atlantic Sunrise, which is preparing to bring additional loads on to that system. I'm proud of our team's exceptional focus on safety and environmental compliance throughout the construction and commissioning process on this large and complex project.

"We are also making great progress on several other projects. In Wyoming, we just announced an expansion on our Jackalope Gas Gathering System and associated Bucking Horse gas processing facility in the Powder River Basin, Niobrara Shale play that will increase processing capacity to 345 million cubic feet per day ('MMcf/d') by the end of 2019 to meet growing customer demand in this underserved growth basin. We also completed major modifications to our Mobile Bay processing plant to enable the handling of large volumes of gas liquids from Shell's Norphlet fields in the Eastern Gulf of Mexico. Additionally, a major expansion of our Oak Grove gas-processing facility in West Virginia is also underway. Construction is going well on Transco's Gulf Connector project, and we realized great progress on the permitting of several other Transco projects in the Northeast and Northwest Pipeline in Seattle."

The midstream business provides natural gas gathering, treating, processing and compression services; NGL production, fractionation, storage, marketing and transportation; deepwater production handling and crude oil transportation services; and is comprised of several wholly owned and partially owned subsidiaries and joint project investments.

Williams Partners reported second-quarter 2018 Modified EBITDA of $1.115 billion, an increase of $39 million from second-quarter 2017. Adjusted EBITDA decreased by $7 million to $1.097 billion.The change in Adjusted EBITDA was driven by a $37 million decrease in proportional EBITDA from joint ventures due primarily to less production on the Discovery system, the absence of $23 million Adjusted EBITDA earned in second-quarter 2017 from the NGL & Petchem Services business primarily as a result of the sale of the Geismar olefins facility, and $26 million increased O&M expenses at Williams Partners' businesses primarily due to increased reliability and integrity costs at Transco. Partially offsetting these decreases was a $46 million increase in service revenues, driven primarily by expansion projects brought online by Transco in 2017 and 2018. Second-quarter 2018 service revenues would have increased by $67 million over second-quarter 2017 if revenue-recognition standards adopted in 2018 had been applied to second-quarter 2017 results.

Year-to-date, the Williams Partners segment reported Modified EBITDA of $2.222 billion, an improvement of $14 million over the same six-month reporting period in 2017. Adjusted EBITDA decreased by $2 million to $2.219 billion. The slight change was driven by the absence of $72 million Adjusted EBITDA earned in 2017 from the NGL & Petchem Services business primarily as a result of the sale of the Geismar olefins facility, a $60 million decrease in proportional EBITDA from joint ventures due primarily to less production on the Discovery system, $38 million increased O&M expenses at Williams Partners' businesses primarily due to increased reliability and integrity costs at Transco, and a $12 million regulatory charge per approved pipeline transportation rates associated with the Tax Reform Act.

Year-to-date, Williams' Other segment reported Modified EBITDA of ($44) million, a decrease of $45 million over the same six-month reporting period in 2017.

Form 10-Q

Non-GAAP Measures

This news release and accompanying materials may include certain financial measures – Adjusted EBITDA, adjusted income (“earnings”), adjusted earnings per share, cash available for dividends and other uses, dividend coverage ratio, distributable cash flow and cash distribution 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 these measures provide investors meaningful insight into results from ongoing operations.

Cash available for dividends and other uses is defined as cash received from our ownership in WPZ and Adjusted EBITDA from our Other segment, less interest, taxes and maintenance capital expenditures associated with our Other segment. We also calculate the ratio of cash available for dividends to the total cash dividends paid (dividend coverage ratio). This measure reflects our cash available for dividends relative to 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 the Company’s assets and the cash that the business is generating.

Neither Adjusted EBITDA, adjusted income, cash available for dividends and other uses or 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.
