TULSA, Okla. –Williams (NYSE: WMB) announced second-quarter 2012 unaudited net income attributable to Williams of $132 million, or $0.21 per share on a diluted basis, compared with net income of $227 million, or $0.38 per share on a diluted basis for second-quarter 2011.

Williams (NYSE:WMB) · 2Q 2012 Financial Results · Aug. 1, 2012 Page 1 of 8

A sharp decline in natural gas liquid (NGL) margins and other factors at Williams Partners, as well as the absence of $56 million in income from discontinued operations in second-quarter 2011, drove the decline in net income during second-quarter 2012.

For the first half of 2012, Williams reported net income of $555 million, or $0.90 per share on a diluted basis, compared with net income of $548 million, or $0.92 per share, for the same time period in 2011.

The increase in year-to-date 2012 net income is primarily due to gains associated with the sale of Williams’ former assets in Venezuela. A number of factors mostly offset this benefit, including the absence of a $124 million income tax benefit primarily associated with a federal settlement that was recorded during first-quarter 2011; and the previously noted decline in NGL margins at Williams Partners and other factors during the second quarter of 2012.

Prior-period results throughout this release have been recast to reflect the separation of Williams’ former exploration and production business on Dec. 31, 2011. The results of the former exploration and production business are reported in discontinued operations for 2011.

Adjusted Income from Continuing Operations

Adjusted income from continuing operations was $138 million, or $0.22 per share, for second-quarter 2012, compared with $172 million, or $0.29 per share for second-quarter 2011. The second-quarter adjusted results are $0.01 higher than the estimate of $0.21 per share that the company provided in its July 23 guidance news release.

The decline in adjusted earnings for the second quarter of 2012 is due to lower results at Williams Partners driven by the sharply lower NGL margins and other factors in the second quarter.

Year-to-date through June 30, adjusted income from continuing operations was $374 million, or $0.61 per share, compared with $341 million, or $0.57 per share for the first half of 2011.

The increase in adjusted income from continuing operations for the first half of 2012 was due to improvement in the Midstream Canada & Olefins segment, driven by a strong first quarter, and decreased interest expense reflecting both corporate debt retirements in December 2011 and increased capitalized interest at Midstream Canada & Olefins associated with construction projects. Lower second-quarter results in the Williams Partners segment partially offset these benefits in the year-to-date period.

Williams (NYSE:WMB) · 2Q 2012 Financial Results · Aug. 1, 2012 Page 2 of 8

Adjusted income from continuing operations reflects the removal of items considered unrepresentative of ongoing operations and is a non-GAAP measure. Reconciliation to the most relevant GAAP measure is attached to this news release.

CEO Comment

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

“As we previously announced, the second-quarter results were driven down by a sharp decline in NGL prices. While we lowered our 2012 and 2013 earnings guidance, we raised our 2014 earnings guidance and reaffirmed our commitment to delivering strong dividend growth.

“We continue to see growth in Williams Partners’ fee-based revenue, particularly in the partnership’s midstream business, where the fee-based revenue was up 19 percent during the second quarter; we expect that trend to continue, as Williams Partners’ fee-based business is expected to be more than 80 percent of its total business by 2014.

“Furthermore, the proposed drop-down of the Geismar facility will significantly benefit both Williams and Williams Partners. We expect to continue to see volatility in the natural gas-to-ethane spread as domestic NGL markets go through growth spurts and periods of oversupply prior to significant new cracking capacity coming online in 2015 and beyond. This will shift Williams Partners’ commodity exposure from ethane to ethylene which we expect to be in tighter supply during this same period.”

Business Segment Results

Williams’ business segments for financial reporting are Williams Partners, Midstream Canada & Olefins, and Other.

Williams Partners

Williams Partners is focused on natural gas transportation, gathering, treating, processing and storage; NGL fractionation; and oil transportation.

For second-quarter 2012, Williams Partners reported segment profit of $339 million, compared with $471 million for second-quarter 2011. Year-to-date through June 30, Williams Partners reported $827 million in segment profit, compared with $908 million for the same period in 2011.

The decline in Williams Partners’ segment profit during the second quarter and year-to-date 2012 is primarily due to a significant decline in NGL prices, primarily in the second quarter of 2012, which led to lower NGL margins and lower marketing margins in Williams Partners’ midstream business. Other factors also negatively affected the second-quarter results, including higher expenses, primarily associated with the partnership’s recent acquisitions. An increase in fee-based revenue, including an increase of 19 percent in the partnership’s midstream business, partially offset the negative impacts of lower NGL prices and other factors.

* Fee-based revenues is a non-GAAP measure. A reconciliation to the most relevant measure included in GAAP is attached to this news release.

The increase in fee-based revenues during second-quarter 2012 was primarily due to new volumes on Williams Partners’ recently acquired Ohio Valley Midstream system and Susquehanna Supply Hub gathering assets in the Marcellus Shale and higher volumes on the Perdido Norte gas and oil pipelines in the western deepwater Gulf of Mexico.

As previously announced, Williams Partners maintained its outlook for strong annual cash distribution growth. It expects an increase of 8 percent in 2012 and 9 percent in both 2013 and 2014 at guidance midpoints.

There is a more detailed description of Williams Partners’ interstate gas pipeline and midstream business results in the partnership’s second-quarter 2012 financial results news release, which is also being issued today.

Midstream Canada & Olefins

Midstream Canada & Olefins includes Williams’ operations in the United States and Canada focused on recovering, transporting, storing and producing ethylene, propylene, NGLs and other related products.

Midstream Canada & Olefins reported segment profit of $68 million for second-quarter 2012, compared with $72 million for second-quarter 2011.

The slight decline in segment profit during second-quarter 2012 was due to lower Canadian NGL product margins driven by lower sales volumes and lower per-unit margins. The lower sales volumes were due to the impact of filling the new Boreal Pipeline, which was placed into service in June. These items were mostly offset by higher Geismar ethylene product margins.

For the first half of 2012, Midstream Canada & Olefins reported segment profit of $171 million, compared with $146 million for the first half of 2011. The increase in segment profit for the first half of 2012 was primarily due to strong

Williams (NYSE:WMB) · 2Q 2012 Financial Results · Aug. 1, 2012 Page 5 of 8

results in the first quarter, driven by higher Geismar ethylene product sales margins and higher Geismar butadiene and other product margins. These items were partially offset by higher operating and maintenance costs and lower Canadian NGL product margins.

Other

The Other segment benefited from gains related to the 2010 sale of the company’s Accroven investment in Venezuela of $53 million in the year-to-date 2012 period and $11 million in the year-to-date 2011 period.

Guidance Unchanged from July 23 Announcement

Williams’ guidance issuedon July 23 for dividends, earnings and capital expenditures for 2012-14 is unchanged. Williams continues to expect to pay a full-year 2012 shareholder dividend of $1.20 per share, a 55 percent increase over 2011. As well, the company expects the full-year dividend it pays shareholders in each of 2013 and 2014 to increase by 20 percent – to $1.44 and $1.75 per share, respectively.

Williams’ revised guidance midpoints for full-year 2012 and 2013 are, respectively, $1.15 and $1.38 for adjusted earnings per share. For 2014, the company’s guidance for adjusted earnings per share is a range with midpoint of $1.95 – a level 59 percent higher than the $1.23 it reported in 2011.

As previously reported on July 23, Williams’ guidance ranges were based on lower near-term NGL prices resulting from record warm winter, high third-party ethylene cracker downtime, growing supplies and other factors.

Williams continues to expect the influence of NGL prices on its earnings to diminish over the next few years as it transitions to a business mix that is increasingly fee-based in its Williams Partners segment. The company’s 2013 and 2014 earnings expectations reflect that shift to greater fee-based business; the benefit of projects coming into service; and some improvement from current NGL market conditions.

The previously reported increase in 2014 earnings guidance is based on the ethylene crack spread recovering to the first-half 2012 level, the strength of the company’s fundamental businesses, growth and some improvement in NGL prices.

For capital and investing expenditures, the company’s guidance includes ranges with midpoints of $6.7 billion in 2012, $3.6 billion in 2013 and $2.6 billion in 2014. The 2013 and 2014 ranges do not include a number of potential projects in development that have not yet been placed into guidance.

Non-GAAP Measures

This press release includes certain financial measures – adjusted segment profit, fee-based revenues, adjusted income from continuing operations (“earnings”) and adjusted earnings per share – that are non-GAAP financial measures as defined under the rules of the Securities and Exchange Commission. Adjusted segment profit, adjusted earnings and adjusted earnings per share measures exclude items of income or loss that the company characterizes as unrepresentative of its ongoing operations. Management believes these measures provide investors meaningful insight into the company’s results from ongoing operations. Fee-based revenues include total revenues less commodity-based and tracked revenue. Such excluded items can be volatile due to changing market conditions, which are largely beyond our management’s control. Fee-based revenues provide investors with information about the growth of our revenues that are not subject to this volatility.

This press 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 widely accepted financial indicators used by investors to compare a company’s performance. In addition, management believes that these measures provide investors an enhanced perspective of the operating performance of the company and aid investor understanding. Neither fee-based revenues, adjusted segment profit, adjusted earnings, nor adjusted earnings per share measures are intended to represent an alternative to revenues, segment profit, net income or earnings per share. 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.
