Williams Reports Third-Quarter 2006 Financial Results

TULSA, Okla., Nov. 2 /PRNewswire-FirstCall/ -- Williams today announced third-quarter 2006 unaudited net income of $106.2 million, or 18 cents per share on a diluted basis, compared with net income of $4.4 million, or 1 cent per share, for third-quarter 2005.

Third-quarter 2006 benefited from a 112 percent increase in natural gas liquids (NGL) sales margins, 22 percent higher natural gas production volumes, and significantly lower levels of forward unrealized mark-to-market losses. These benefits were partially offset by higher operating and maintenance costs.

Quarterly Summary Information 3Q 2006 3Q 2005 Per share amounts are reported on a diluted basis millions millions per share millions per share Income from continuing operations $110.1 $0.19 $5.7 $0.01 Loss from discontinued operations ($3.9) ($0.01) ($1.3) $0.00 Net income $106.2 $0.18 $4.4 $0.01 Recurring income (loss) from continuing operations* $113.4 $0.19 ($4.6) ($0.01) After-tax mark-to-market adjustments $59.0 $0.09 $129.9 $0.23 Recurring income from continuing operations - after mark-to-market adjustment* $172.4 $0.28 $125.3 $0.22 Year-to-Date Summary Information YTD 2006 YTD 2005 Per share amounts are reported on a diluted basis millions per share millions per share Income from continuing operations $177.3 $0.29 $248.6 $0.42 Loss from discontinued operations ($15.2) ($0.02) ($1.8) $0.00 Net income $162.1 $0.27 $246.8 $0.42 Recurring income from continuing operations* $361.9 $0.60 $259.7 $0.44 After-tax mark-to-market adjustments $165.5 $0.27 $97.6 $0.16 Recurring income from continuing operations - after mark-to-market adjustment* $527.4 $0.87 $357.3 $0.60 * A schedule reconciling income from continuing operations to recurring income from continuing operations and mark-to-market adjustments (non- GAAP measures) is available at http://www.williams.com/ and as an attachment to this press release.

Year-to-date through Sept. 30, Williams reported net income of $162.1 million, or 27 cents per share on a diluted basis, compared with net income of $246.8 million, or 42 cents per share, for the same period in 2005.

Results for the first nine months of 2006 are significantly reduced by the after-tax impact of legacy litigation charges recorded in the second quarter totaling approximately $175 million.

While these nonrecurring charges obscure the company's strong performance overall in 2006, Williams has realized significantly higher NGL sales margins and continues to rapidly increase its natural gas production in the western United States. Production in the Piceance Basin - the company's cornerstone property for production growth - increased 31 percent year-over-year in the third quarter.

Recurring Results Adjusted to Remove the Effect of Mark-to-Market Accounting

To provide an added level of disclosure and transparency, Williams continues to provide an analysis of recurring earnings adjusted to remove all mark-to-market effects from its Power business.

Recurring earnings exclude items of income or loss that the company characterizes as unrepresentative of its ongoing operations.

Recurring income from continuing operations - after adjusting for the mark-to-market effect to reflect income as though mark-to-market accounting had never been applied to Power's derivatives - increased 38 percent from a year ago to $172.4 million, or 28 cents per share, in third-quarter 2006 from $125.3 million, or 22 cents per share in third-quarter 2005.

Year-to-date through Sept. 30, recurring income from continuing operations - adjusted to remove the effect of mark-to-market accounting - was $527.4 million, or 87 cents per share, an increase of 48 percent compared with $357.3 million, or 60 cents per share, for the same period in 2005.

The quarterly and year-to-date improvement is primarily the result of higher NGL sales margins; increased natural gas production, particularly in the Piceance and Powder River basins; increased gathering and processing revenue; and improved results in the power portfolio.

A reconciliation of the company's income from continuing operations to recurring income from continuing operations and mark-to-market adjustments accompanies this news release.

Williams Increases Guidance Again

Williams has raised its guidance for 2006 based on the company's strong operating performance through three quarters, anticipated increases in natural gas production volumes, and its outlook for energy commodity prices - key factors that have driven higher sales margins for natural gas liquids.

The company now expects $1.05 to $1.20 for diluted earnings per share in 2006 on a recurring basis adjusted to remove the effect of mark-to-market accounting, compared with the previous expectation of 95 cents to $1.20.

Williams also is raising its expectations for 2006 consolidated segment profit on a recurring basis adjusted to remove the effect of mark-to-market accounting. The company now expects approximately $1.8 billion to $2.02 billion for this measure. Williams previously expected $1.69 billion to $2.01 billion.

Williams also modified its expected capital budget for 2006 through 2008. The increase in planned capital spending for 2007 and 2008 is for Midstream growth projects - primarily in the western deepwater Gulf of Mexico - that are expected to provide attractive returns on investment.

Updated Cap-Ex Guidance NEW PREVIOUS 2006 $2.175 billion - $2.375 billion $2.2 billion - $2.4 billion 2007 $2 billion - $2.2 billion $1.775 billion - $1.975 billion 2008 $1.8 billion - $2.05 billion $1.575 billion-$1.825 billion CEO Perspective

"This is the second time we've raised our earnings guidance this year," said Steve Malcolm, Williams' chairman, president and chief executive officer. "And we like the momentum we have going into 2007 and beyond."

"Our outlook is based on the fact that our natural gas production continues to rapidly climb, our older below-market hedges for that production are beginning to roll off, we see sustained strength in NGL sales margins, and our Midstream business has sizeable opportunities on the horizon.

"As we've shown, we're poised to capture value creation with diligence, determination and fiscal discipline. Our businesses offer unique capabilities that our customers value. Our assets are strategically located in areas where we can capture meaningful growth. The scale of our operations gives us competitive advantages. And our liquidity and cash flow remain very robust.

"Overall, our portfolio of businesses is performing extremely well. Our business diversity is designed to help us do well in different price environments. We have a great deal of balance that is evidenced in our revenue streams.

"This year is a perfect example. Our Midstream business has provided a natural hedge to the price exposure we have in Exploration & Production. So while natural gas prices have been lower, the NGL margins in Midstream have been higher - significantly higher."

Business Segment Performance: Substantial Increase in 3Q Segment Profit

Consolidated results include segment profit for Williams' primary businesses - Exploration & Production, Midstream Gas & Liquids, Gas Pipeline and Power - as well as results reported in the Other segment.

Recurring Segment Profit Adjusted for Mark-to-Market Effect Amounts are reported in millions 3Q YTD 2006 2005 2006 2005 Segment profit $395.8 $204.5 $1,101.0 $970.6 Nonrecurring adjustments $1.1 ($35.5) $60.8 ($0.3) Recurring segment profit $396.9 $169.0 $1,161.8 $970.3 Reverse forward unrealized mark-to- market (gains) losses $15.5 $141.1 $11.1 ($102.1) Add realized mark-to-market gains previously recognized $80.0 $71.9 $256.9 $262.2 Recurring segment profit after mark- to-market adjustments $492.4 $382.0 $1,429.8 $1,130.4

Williams' businesses reported consolidated segment profit of $395.8 million in the third-quarter this year, 94 percent higher than $204.5 million a year ago.

These significantly higher results in third-quarter 2006 are primarily attributable to higher margins for NGL sales, significantly lower levels of forward unrealized mark-to-market losses and increased natural gas production. These benefits were partially offset by higher operating and maintenance costs.

For the first three quarters of 2006, Williams' businesses reported consolidated segment profit of $1.1 billion, an increase of 13 percent compared with $970.6 million for the same period in 2005.

Results for the first nine months of 2005 benefited from $102.1 million of forward unrealized mark-to-market gains in Power, compared with a forward unrealized loss of $11.1 million for the same period in 2006. The 2006 period also includes approximately $70 million in litigation accruals associated with the Gulf Liquids verdict earlier this year.

On a basis adjusted to remove the effect of nonrecurring items and mark- to-market accounting, Williams had recurring consolidated segment profit of $492.4 million in third-quarter 2006, compared with $382.0 million a year ago - an increase of 29 percent. On the same basis, Williams had recurring consolidated segment profit of approximately $1.4 billion in the first three quarters of 2006, compared with approximately $1.1 billion for the same period in 2005 - an increase of 26 percent.

The improvement in 2006 on an adjusted basis is primarily the result of significantly higher results in Midstream, Power and Exploration & Production.

For the first three quarters of 2006, net cash provided by operating activities was approximately $1.3 billion, compared with approximately $1.1 billion for the same period in 2005. Net cash generated this year is primarily being reinvested in capital expenditures.

Williams invested approximately $1.8 billion in capital expenditures in the first nine months this year, essentially doubling investments of approximately $886 million in the same period a year ago.

Exploration & Production: Volumes Up 22% From Year Ago

Exploration & Production includes natural gas production and development in the U.S. Rocky Mountains, San Juan Basin and Mid-Continent, and oil and natural gas operations in South America.

This business reported third-quarter 2006 segment profit of $144.5 million, compared with segment profit of $158.8 million a year ago. The third quarter of 2005 included the benefit of a $21.7 million gain on the sale of certain properties in the Powder River Basin.

Average daily production from domestic and international interests in third-quarter 2006 totaled 831 MMcfe, an increase of 22 percent compared with volumes of 682 MMcfe in third-quarter 2005.

Third-quarter 2006 average daily production in the Piceance Basin was 430 MMcfe - up 31 percent compared with 329 MMcfe in third-quarter 2005.

Production in the Powder River Basin also increased - up 23 percent to 147 MMcfe, compared with 120 MMcfe a year ago. Increased production in the Powder River primarily is coming from volumes in the Big George area of the basin.

The benefit of higher production volumes in the third quarter of 2006 was partially offset by 10 percent lower domestic net realized average prices; increased lease operating expenses; higher depreciation, depletion and amortization; and higher general and administrative expenses due to increased business activities and generally higher industry costs. However, third- quarter 2006 included a $5 million unrealized gain from hedge ineffectiveness and certain basis swaps not designated as hedges, compared with a $16 million unrealized loss for third-quarter 2005.

For the first nine months of 2006, Exploration & Production reported segment profit of $411.9 million, an increase of 8 percent compared with $380.8 million for the first three quarters of 2005.

The improvement in the first three quarters of 2006 primarily reflects increased production volumes. The first nine months of 2006 also include a $21 million unrealized gain from hedge ineffectiveness and certain basis swaps not designated as hedges, compared with a $16 million unrealized loss for the same period in 2005.

Year-to-date increases in 2006 were partially offset by the same expense items previously noted for the third quarter, as well as the absence of gains totaling $29.6 million on the sale of certain assets in 2005.

Williams now has 24 rigs operating in the Piceance Basin of western Colorado - 9 more than it had at this time a year ago. The rig count includes eight new-generation drilling rigs that are purpose-built for conditions in the tight-sands development. Two more of the new rigs are scheduled for delivery later this year.

Williams is on pace to invest $1.15 billion to $1.25 billion in Exploration & Production in 2006. These investments primarily focus on increasing the pace of developing the company's natural gas reserves.

Williams has narrowed the range of segment profit it expects from Exploration & Production in 2006 based on lower domestic net realized prices and higher lease operating expenses in the third quarter. The company now expects $550 million to $600 million in segment profit for this business. The company's prior guidance was $550 million to $650 million.

Midstream Gas & Liquids: 3Q Segment Profit Rises 75 Percent

Midstream provides gathering and processing services for oil and gas producers, along with NGL services and olefins production.

This business reported segment profit of $212.2 million in the third quarter, up 75 percent compared with $121.1 million a year ago.

The significant increase in Midstream's results is primarily from higher margins realized from the company's NGL sales. Per-unit margins in third- quarter 2006 were approximately 112 percent higher than margins in the same period a year ago. Williams markets natural gas liquids via equity volumes the company retains as payment-in-kind under certain processing contracts.

In addition, Williams experienced strong growth in production handling volumes and revenues in the deepwater Gulf of Mexico, and higher fee-based gathering and processing revenues. The 2006 quarter also benefited from $7.9 million in gains on asset sales. These benefits were partially offset by higher operating expenses, a $10.6 million adjustment to increase accrued accounts payable and a $5.2 million loss associated with an asset abandonment.

In third-quarter 2006, Midstream sold 334.0 million gallons of NGL equity volumes - 21 percent higher than equity sales of 276.4 million gallons in third-quarter 2005.

For the first nine months of 2006, Midstream reported segment profit of $494.4 million, 38 percent higher than $358.8 million for the first three quarters of 2005.

The improvement in 2006 primarily reflects a $164.2 million increase in NGL sales margins; significantly higher production handling volumes and revenues in the deepwater Gulf of Mexico; and higher fee-based gathering and processing revenues. These increases were partially offset by higher operating expenses and approximately $70 million in litigation accruals associated with the Gulf Liquids matter.

Year-to-date through Sept. 30, the sale of Williams' NGL equity volumes has generated margins of $323.4 million, 103 percent higher than margins of $159.2 million for the same period in 2005. Higher margins during the first three quarters of 2006 are primarily the result of the difference between higher liquids prices - which typically track closely with crude oil prices - and lower natural gas prices.

The Cameron Meadows natural gas processing plant in Louisiana's Cameron Parish is returning to its full design capacity after being damaged by Hurricane Rita in September 2005. The plant is expected to be available to process up to 500 MMcf/d of natural gas in early November as crews finalize the startup procedures on the plant's second processing unit. Cameron Meadows had been operating at about half of its design capacity since February.

Williams is raising its guidance again for segment profit it expects from Midstream. The company now expects $675 million to $750 million in segment profit for this business in 2006 based on its performance in the first three quarters and Williams' outlook for strong NGL prices. The company's prior guidance in August was $550 million to $675 million in segment profit for Midstream.

Gas Pipeline: Capacity Replacement Project Nearing Completion

Gas Pipeline primarily delivers natural gas to markets along the Eastern Seaboard, in the Northwest, and in Florida. This business reported third- quarter 2006 segment profit of $109.0 million, down 32 percent compared with $161.1 million a year ago.

Results for the third quarter of 2006 were reduced by approximately $22 million in higher selling, general and administrative costs primarily due to higher personnel costs, property insurance costs and information systems support costs. In addition, the results reflect approximately $8 million in lower equity earnings and higher operating and maintenance costs related to pipeline assessment and repair costs.

The third-quarter of 2005 benefited from a $14 million favorable adjustment from the resolution of litigation associated with Gas Pipeline's fuel tracker filings.

New rates for both of Williams' wholly-owned interstate transmission systems - Transco and Northwest Pipeline - will be effective, subject to refund, in first-quarter 2007. Northwest Pipeline filed its rate case with the Federal Energy Regulatory Commission on June 30. Transco filed its rate case Aug. 31. The filings reflect, among other things, current levels of operating costs and rate base.

For the first nine months of 2006, Gas Pipeline reported segment profit of $366.4 million, down 26 percent compared with $493.0 million for the same period in 2005.

The reduction for the first three quarters of 2006 is attributable to higher operating and maintenance costs; higher selling, general and administrative costs, including the absence of a $34.8 million benefit in prior-period adjustments recorded in 2005; and the absence of the $14 million benefit of the 2005 fuel tracker settlement. The increased costs are primarily due to the same factors previously mentioned for the third quarter.

In July, Transco filed an application with the Federal Energy Regulatory Commission to provide additional capacity to the greater Washington D.C. and Baltimore metropolitan areas. The proposal, known as the Potomac Expansion, is designed to increase firm transportation capacity by 165,000 dekatherms per day beginning in November 2007.

In August, the commission also issued a certificate enabling Northwest Pipeline to proceed with a 37-mile expansion in Colorado known as the Parachute Lateral project. The 450,000-dekatherm expansion is scheduled to be completed by January 2007.

Northwest Pipeline expects to have its Capacity Replacement project between Sumas, Wash., and Washougal, Wash., in service by December. The company abandoned 268-miles of 26-inch diameter pipeline and replaced its 360,000 dekatherms of capacity with 80-miles of 36-inch diameter pipeline in four sections along the same corridor. Startup operations on the new pipeline sections began the week of Oct. 23.

Williams has narrowed the range of segment profit it expects from Gas Pipeline. The company now expects $475 million to $500 million in segment profit for this business in 2006. Williams previously expected $475 million to $520 million in segment profit for Gas Pipeline.

Power: Solid Performance as Expected

Power manages a portfolio of more than 7,000 megawatts and provides services that support Williams' natural gas businesses.

Power Recurring Segment Profit (Loss) Adjusted for Mark-to-Market Effect Amounts are reported in millions 3Q YTD 2006 2005 2006 2005 Segment loss ($69.7) ($226.4) ($171.8) ($187.3) Nonrecurring adjustments ($9.2) $0.4 ($9.2) $24.9 Recurring segment loss ($78.9) ($226.0) ($181.0) ($162.4) Mark-to-market adjustments -- net $95.5 $213.0 $268.0 $160.1 Recurring segment profit (loss) after MTM adjustments $16.6 ($13.0) $87.0 ($2.3)

Power reported a third-quarter 2006 segment loss of $69.7 million, compared with a segment loss of $226.4 million for third-quarter 2005. Results include the effect of forward noncash unrealized mark-to-market gains and losses.

The improved results in third-quarter 2006 are primarily the result of lower noncash unrealized mark-to-market losses, higher accrual portfolio earnings and the benefit of a $12.7 million reduction in contingent obligations associated with a former business. The improvement was partially offset by a $3.5 million litigation accrual.

On a basis adjusted for the effect of mark-to-market accounting, Power reported recurring segment profit of $16.6 million in third-quarter 2006, compared with a recurring segment loss of $13.0 million in the 2005 period.

The improvement in third-quarter 2006 recurring segment profit adjusted to remove the effect of mark-to-accounting reflects the benefit of having additional megawatts economically hedged on Power's tolling positions. Third- quarter 2006 adjusted results include approximately $13 million of losses related to the write-down of natural gas storage inventory due to falling prices and $7 million of certain related realized hedge losses. These losses - on a basis adjusted for mark-to-market accounting - are timing-related only. The company expects to recover these losses since the inventory is hedged at fixed prices.

For the first nine months of 2006, Power reported a segment loss of $171.8 million, compared with a segment loss of $187.3 million for the first three quarters of 2005. The improved results in 2006 are primarily the result of higher accrual portfolio earnings and a $24.8 million gain on the sale of certain third party receivables in first-quarter 2006, offset by lower noncash unrealized mark-to-market earnings.

The 2006 period includes forward unrealized mark-to-market losses of $11.1 million, compared with forward unrealized mark-to-market gains of $102.1 million in the first nine months of 2005. The year-over-year variance resulted primarily from commodity price changes on fewer nondesignated contracts subject to mark-to-market accounting.

For the first nine months of 2006, Power reported a recurring segment profit on a basis to remove the effect of mark-to-market accounting of $87.0 million, significantly improved compared with a loss $2.3 million for the first three quarters of 2005.

The year-to-date improvement primarily reflects the benefits of having additional megawatts economically hedged on Power's tolling positions, the liquidation of certain non-core basis positions in the gas portfolio and lower expenses from the positive effect of a gain on the sale of certain third-party receivables in the first quarter.

The 2006 adjusted results also include $20 million of storage-related losses for the write-down of natural gas inventory due to falling prices and $30 million of certain related realized hedge losses. These losses - on a basis adjusted for mark-to-market accounting - are timing-related only. The company expects to recover these losses since the inventory is hedged at fixed prices.

For 2006, Williams now expects a segment loss of $190 million to $240 million from Power, which includes year-to-date unrealized mark-to-market losses on derivative contracts but assumes no future change in fair value on these contracts. Williams previously expected a segment loss of $150 million to $200 million from Power.

Williams continues to expect Power to generate 2006 recurring segment profit of $75 million to $125 million after removing the effect of mark-to- market accounting.

The tax rate applied to Midstream's international contract dispute settlement in 1st quarter 2006 is 34%. The tax rate applied to nonrecurring items for 2nd quarter 2006 has been adjusted for the effect of nondeductible expenses associated with securities litigation settlement and related costs and early debt retirement costs related to our convertible debt. Note: The sum of earnings (loss) per share for the quarters may not equal the total earnings (loss) per share for the year due to changes in the weighted-average number of common shares outstanding.
