ONEOK Announces Higher Second-quarter 2012 Financial Results;

Updates 2012 Earnings Guidance

TULSA, Okla. – July 31, 2012 – ONEOK, Inc. (NYSE: OKE) today announced second-quarter 2012 earnings of 29 cents per diluted share, compared with 25 cents per diluted share on a split-adjusted basis for the same period last year. Second-quarter net income attributable to ONEOK was $61.0 million, compared with $55.1 million for the same period in 2011.

Net income attributable to ONEOK for the six-month period ended June 30, 2012, was $183.9 million, or 87 cents per diluted share, compared with $185.3 million, or 85 cents per diluted share on a split-adjusted basis for the same period last year.

ONEOK updated its 2012 net income guidance range to $345 million to $375 million, compared with the previous range of $360 million to $410 million. The updated guidance reflects lower expected earnings in the energy services and natural gas distribution segments, offset partially by higher expected earnings in the ONEOK Partners segment.

“Our ONEOK Partners segment posted strong second-quarter results, benefiting from continued favorable natural gas liquids price differentials, increased natural gas liquids volumes gathered, and higher natural gas volumes gathered and processed, as a result of recently completed growth projects,” said John W. Gibson, ONEOK chairman and chief executive officer.

“Our natural gas distribution segment delivered solid results, while our energy services segment continues to operate in a challenging marketing environment,” Gibson said.

ONEOK’s second-quarter 2012 operating income was $234.1 million, compared with $216.2 million for the second quarter 2011.

Second-quarter 2012 results benefited from solid performance in the ONEOK Partners segment including higher natural gas liquids (NGL) optimization margins resulting from favorable NGL price differentials and increased NGL transportation capacity available for optimization activities, and higher NGL volumes gathered in the natural gas liquids business; and higher natural gas volumes gathered and processed, offset partially by lower natural gas and NGL product prices in the natural gas gathering and processing business.

Second-quarter 2012 results for the natural gas distribution segment were slightly higher due primarily to higher rates and surcharge recoveries in Texas and Kansas, offset partially by higher depreciation expense due to increased capital expenditures.

The energy services segment had lower second-quarter 2012 results due primarily to lower transportation and premium-services margins.

Year-to-date 2012 operating income was $560.0 million, compared with $544.5 million for the same period last year.

The increase in year-to-date 2012 results was driven primarily by higher NGL optimization and exchange margins resulting from favorable NGL price differentials and increased NGL fractionation and transportation capacity available for optimization activities; higher NGL volumes gathered and fractionated in the natural gas liquids business; and higher natural gas volumes gathered and processed, offset partially by lower natural gas prices and NGL product prices in the ONEOK Partners segment.

These increases were offset by lower margins in the energy services segment due primarily to lower storage and marketing margins, net of hedging activities, including a required $29.9 million reclassification of losses on certain financial contracts and a $10.3 million non-recurring goodwill impairment charge in the first quarter 2012, and lower transportation margins, net of hedging activities.

Operating costs for the second quarter 2012 were $231.3 million, compared with $223.6 million in the same period last year. Operating costs for the six-month 2012 period were $455.3 million, compared with $445.3 million in the same period last year. The increases for both the three- and six-month 2012 periods were due primarily to the ONEOK Partners segment’s expanding operations as a result of several internal growth projects that were placed in service and scheduled maintenance costs.

In February 2012, ONEOK sold its retail natural gas marketing business, which was accounted for in the natural gas distribution segment, to Constellation Energy Group, Inc. for $32.9 million, including working capital, and recognized an after-tax gain of $13.5 million. Financial information for this business is reflected as discontinued operations.

BUSINESS-UNIT RESULTS:

ONEOK Partners

ONEOK Partners’ second-quarter 2012 operating income was $228.1 million, compared with $202.0 million in the same period last year.

Second-quarter results reflect:

A $25.7 million increase in the natural gas gathering and processing business due primarily to volume growth in the Williston Basin from the new Garden Creek plant and increased drilling activity, which resulted in higher natural gas volumes gathered, compressed, processed, transported and sold, and higher fees, offset partially by lower natural gas volumes gathered in the Powder River Basin as a result of continued production declines and reduced drilling activity;

An $18.0 million increase in the natural gas liquids business from higher NGL volumes gathered in the Mid-Continent and Rocky Mountain regions and Texas, higher NGL volumes fractionated in the Mid-Continent region and contract renegotiations for higher fees associated with its NGL exchange-services activities, offset partially by lower

volumes fractionated in Texas due to scheduled maintenance in May 2012 at the Mont Belvieu, Texas, fractionation facility;

A $10.9 million increase in the natural gas liquids business from higher optimization margins, which consisted of a $24.8 million increase from favorable NGL price differentials and additional transportation capacity available for optimization activities resulting from the completed expansions of the Arbuckle and Sterling I pipelines; offset partially by a $13.8 million decrease due primarily to lower NGL product sales and higher NGL inventory held as a result of scheduled maintenance at the Mont Belvieu fractionation facility. The partnership expects to fractionate this NGL inventory and realize margins resulting from the physical-forward sale of this inventory by the end of 2012;

·	A $6.0 million increase due to higher storage margins in the natural gas liquids business as a result of favorable contract renegotiations;

·	A $10.1 million decrease in the natural gas gathering and processing business from lower realized natural gas and NGL product prices, particularly ethane and propane, offset partially by higher condensate prices;

·	An $8.6 million decrease in the natural gas gathering and processing business due primarily to higher compression costs and third-party transportation and processing costs associated with volume growth, primarily in the Williston Basin; and

·	A $2.2 million decrease in the natural gas liquids business due to the impact of operational measurement losses.

For the first six months 2012, the ONEOK Partners segment posted operating income of $484.1 million, compared with $379.6 million in the same period a year earlier.

Six-month 2012 results, compared with the same period last year, reflect:

A $71.2 million increase in optimization margins in the natural gas liquids business, which consisted of an $84.8 million increase from favorable NGL price differentials and additional fractionation and transportation capacity available for optimization activities resulting from a fractionation services agreement with a third party and the completed expansions of the Arbuckle and Sterling I pipelines; offset partially by a $13.8 million decrease due primarily to lower NGL product sales and higher NGL inventory held as a result of scheduled maintenance at the Mont Belvieu fractionation facility. The partnership expects to fractionate this NGL inventory and realize margins resulting from the physical-forward sale of this inventory by the end of 2012;

A $52.9 million increase in the natural gas gathering and processing business due primarily to volume growth in the Williston Basin from the new Garden Creek plant and increased drilling activity, which resulted in higher natural gas volumes gathered, compressed, processed, transported and sold, and higher fees, offset partially by lower natural gas volumes gathered in the Powder River Basin as a result of continued production declines and reduced drilling activity;

A $35.8 million increase in the natural gas liquids business from higher NGL volumes gathered and fractionated and favorable contract renegotiations for higher fees associated with its NGL exchange-services activities, offset partially by higher costs associated with NGL volumes fractionated by third parties;

·	An $8.7 million increase in the natural gas liquids business due to higher storage margins as a result of favorable contract renegotiations;

·	A $4.2 million increase in the natural gas liquids business due to the impact of operational measurement losses in the same period last year;

·	A $15.3 million decrease in the natural gas gathering and processing business from lower realized natural gas and NGL product prices, particularly ethane and propane, offset partially by higher condensate prices;

·	A $14.6 million decrease in the natural gas gathering and processing business due primarily to higher compression costs and third-party transportation and processing costs associated with volume growth, primarily in the Williston Basin;

·	A $3.7 million decrease in the natural gas pipelines business primarily from lower realized natural gas prices on its retained fuel position; and

·	A $1.9 million decrease in the natural gas liquids business in isomerization margins from lower isomerization volumes, offset partially by wider price differentials between normal butane and iso-butane.

Second-quarter 2012 operating costs were $123.4 million, compared with $113.6 million in the second quarter 2011. Six-month 2012 operating costs were $239.2 million, compared with $222.3 million in the same period a year earlier.

The increases for both the three- and six-month 2012 periods were due primarily to increased expenses for materials, utilities and outside services associated with scheduled maintenance; and increased employee-related costs associated with the growth of ONEOK Partners’ operations and completed projects in the natural gas gathering and processing and natural gas liquids businesses.

Key Statistics: More detailed information is listed on page 20 of the tables.

Natural gas gathered was 1,079 billion British thermal units per day (BBtu/d) in the second quarter 2012, up 5 percent compared with the same period last year due to increased drilling activity in the Williston Basin and in western Oklahoma, and the completion of the partnership’s new Garden Creek plant in the Williston Basin; offset partially by continued production declines and reduced drilling activity in the Powder River Basin in Wyoming; and up 3 percent compared with the first quarter 2012;

Natural gas processed was 823 BBtu/d in the second quarter 2012, up 21 percent compared with the same period last year due to increased drilling activity in the Williston Basin and western Oklahoma, and the completion of the partnership’s new Garden Creek plant in the Williston Basin; and up 7 percent compared with the first quarter 2012;

Natural Gas Distribution

Prior reporting periods for the natural gas distribution segment have been recast to exclude retail marketing operations that were sold in February 2012. Those operations are now reflected as discontinued operations.

The natural gas distribution segment reported operating income of $21.7 million in the second quarter 2012, compared with $20.2 million in the second quarter 2011.

Second-quarter results reflect higher rates and surcharge recoveries in Texas and Kansas offset by higher depreciation expense from increased capital expenditures, including investments in automated meter-reading devices in Oklahoma.

For the six months 2012, operating income was $120.6 million, compared with $123.3 million in the same period in 2011.

Six-month 2012 results reflect higher depreciation expense from increased capital expenditures, including investments in automated meter-reading devices in Oklahoma; and a decrease in transportation margins in Kansas and Oklahoma due to warmer-than-normal weather in the first quarter 2012 that reduced commercial customer demand that is not subject to weather normalization, offset partially by higher rates and surcharge recoveries in Texas and Kansas.

Second-quarter 2012 operating costs were $103.8 million, compared with $104.5 million in the second quarter 2011. Six-month 2012 operating costs were $208.7 million, compared with $209.2 million in the same period a year earlier. The decreases for both the three- and six-month 2012 periods were due primarily to lower share-based compensation costs offset partially by higher outside services, legal expenses and pension costs.

Key Statistics: More detailed information is listed on page 20 of the tables.

·	Residential natural gas sales volumes were 9.0 billion cubic feet (Bcf) in the second quarter 2012, down 27 percent compared with the same period last year due to warmer temperatures in the second quarter 2012;

·	Total natural gas volumes sold were 15.3 Bcf in the second quarter 2012, down 12 percent compared with the same period last year due to warmer temperatures in the second quarter 2012;

·	Total natural gas volumes delivered were 61.2 Bcf in the second quarter 2012, down 4 percent compared with the same period last year; and

·	Total natural gas transportation volumes were 45.8 Bcf in the second quarter 2012, down 1 percent compared with the same period last year due to warmer temperatures in the second quarter 2012.

Energy Services

The energy services segment reported a second-quarter 2012 operating loss of $15.1 million, compared with an operating loss of $5.8 million in the same period in 2011.

The decrease in second-quarter 2012 operating income, compared with the same period in 2011, reflects:

·	An $8.7 million decrease in transportation margins, net of hedging, primarily due to lower hedge settlements in 2012; and

·	A $2.1 million decrease in premium-services margins due to lower demand fees.

For the first six months 2012, the energy services segment posted an operating loss of $45.8 million, compared with operating income of $42.0 million in the same period a year earlier.

Six-month 2012 results, compared with the same period last year, reflect:

A $65.4 million decrease in storage and marketing margins due primarily to a $29.9 million decrease related to the continued decline in natural gas prices that resulted in the required reclassification of losses on certain financial contracts in the first quarter 2012 that were used to hedge forecasted purchases of natural gas. The combination of the cost bases of the forecasted purchases of inventory and the financial contracts exceed the amount expected to be recovered through sales of that inventory, after considering related sales hedges, which required reclassification of the loss from accumulated other comprehensive income (loss) to current period earnings; a $15.1 million decrease primarily due to lower realized seasonal natural gas storage price differentials; a $9.3 million decrease due to unrealized fair value changes on non-qualifying economic hedges; and a $6.2 million decrease primarily to decreased marketing activities;

·	A $13.6 million decrease in transportation margins, net of hedging, primarily due to lower hedge settlements in 2012 and the release of contracted transportation capacity to a third-party; and

·	A $3.2 million decrease in premium-services margins due to lower demand fees.

Additionally, this segment recorded a $10.3 million non-recurring goodwill impairment charge in the first quarter 2012.

Second-quarter 2012 operating costs were $4.6 million, compared with $5.3 million in the second quarter 2011. Six-month 2012 operating costs were $9.4 million, compared with $13.3 million in the same period a year earlier. The decreases for both the three- and six-month 2012 periods were due primarily to lower employee-related costs.

2012 EARNINGS GUIDANCE UPDATED

ONEOK’s 2012 net income is expected to be in the range of $345 million to $375 million, compared with its previously announced range of $360 million to $410 million. The updated guidance reflects lower expected earnings in the energy services and natural gas distribution segments offset partially by higher expected earnings in the ONEOK Partners segment. Additional information is available in the guidance tables on the ONEOK website.

The midpoint of ONEOK’s 2012 operating income guidance decreased to $1.104 billion, compared with its previous guidance midpoint of $1.132 billion. The midpoint for ONEOK’s 2012 net income guidance is $360 million, compared with its previous guidance of $385 million.

The midpoint of the ONEOK Partners segment’s 2012 operating income guidance increased to $948 million, compared with its previous guidance of $910 million. The updated 2012 guidance reflects higher expected earnings in the natural gas liquids business and lower expected earnings in the natural gas gathering and processing business.

The average unhedged prices assumed for the second half of 2012 at ONEOK Partners are $85.42 per barrel for New York Mercantile Exchange (NYMEX) crude oil, $2.88 per MMBtu for NYMEX natural gas and $0.71 per gallon for composite natural gas liquids. Previous guidance released on May 23, 2012, assumed $97.75 per barrel for NYMEX crude oil,

July 31, 2012

Page 11

$3.30 per MMBtu for NYMEX natural gas and $1.20 per gallon for composite natural gas liquids.

Currently, ONEOK Partners estimates that in its natural gas gathering and processing business, a 1-cent-per-gallon change in the composite price of NGLs would change annual net margin by approximately $2.5 million. A $1.00-per-barrel change in the price of crude oil would change annual net margin by approximately $1.3 million. Also, a 10-cent-per-MMBtu change in the price of natural gas would change annual net margin by approximately $2.3 million. All of these sensitivities exclude the effects of hedging and assume normal operating conditions.

Additionally, ONEOK Partners estimates that in the natural gas liquids business, the Conway-to-Mont Belvieu OPIS average ethane in ethane/propane mix price differential is expected to be 28 cents for the second half of 2012, compared with its previous full-year 2012 guidance of 32 cents.

The midpoint of the natural gas distribution segment’s 2012 operating income guidance has been updated to $215 million, compared with its previous guidance of $223 million, reflecting lower margins due to warmer than normal weather.

The midpoint of the energy services segment’s 2012 operating income guidance has been updated to a loss of $60 million, compared with its previous guidance of $0 million. Updated 2012 guidance reflects the $29.9 million required reclassification of losses on certain financial contracts and the $10.3 million non-recurring goodwill impairment charge, both occurring in the first quarter 2012. This segment also expects lower transportation and premium-services margins in 2012. Additional information on the energy services segment’s revised guidance is available in the guidance tables on the ONEOK website.

Capital expenditures for 2012 are expected to be approximately $2.3 billion, comprised of approximately $2.0 billion at ONEOK Partners and $304 million on a stand-alone basis.

On a stand-alone basis, the midpoint of ONEOK’s 2012 guidance for cash flow before changes in working capital has been updated to $695 million, compared with its previous guidance of $740 million. Cash flow before changes in working capital is expected to exceed capital expenditures and dividends by $115 million to $145 million. Additional information is available in the guidance tables on the ONEOK website.

ONEOK’s 2012 earnings guidance also includes projected 2.5-cent-per-quarter increases in unitholder distributions from ONEOK Partners, subject to ONEOK Partners board approval.

NON-GAAP (GENERALLY ACCEPTED ACCOUNTING PRINCIPLES) FINANCIAL MEASURE

ONEOK has disclosed in this news release stand-alone cash flow, before changes in working capital, which is a non-GAAP financial measure. Stand-alone cash flow, before changes in working capital, is used as a measure of the company’s financial performance. Stand-alone cash flow, before changes in working capital, is defined as net income less the portion attributable to non-controlling interests, adjusted for equity in earnings and distributions received from ONEOK Partners, and ONEOK’s stand-alone depreciation, amortization and impairments, deferred income taxes, and certain other items.

The non-GAAP financial measure described above is useful to investors because the measurement is used as a measurement of financial performance of the company’s fundamental business activities. ONEOK stand-alone cash flow, before changes in working capital, should not be considered in isolation or as a substitute for net income or any other measure of financial performance presented in accordance with GAAP.

This non-GAAP financial measure excludes some, but not all, items that affect net income. Additionally, this calculation may not be comparable with similarly titled measures of other companies. A reconciliation of stand-alone cash flow, before changes in working capital, to net income is included in the financial tables.
