Atmos Energy Corporation’s Nonutility Performance

Drives Fiscal 2006 First Quarter Results

DALLAS (February 7, 2006)—Atmos Energy Corporation (NYSE: ATO) today reported consolidated results for its first quarter of fiscal 2006 ending December 31, 2005.

• For the fiscal 2006 first quarter net income was $71.0 million, or $0.88 per diluted share, up approximately 19 percent from net income of $59.6 million, or $0.79 per diluted share in the prior-year quarter, despite a 5 million increase in weighted average shares outstanding year over year.

• Nonutility businesses contributed $22.6 million, or $0.28 per diluted share in the fiscal 2006 first quarter, largely due to capturing favorable arbitrage spreads during a period of unprecedented market volatility.

• Gross profit for the fiscal 2006 first quarter was negatively affected by $8.0 million from weather that was 7 percent warmer than normal, as adjusted for jurisdictions with weather-normalized rates. Warmer-than-normal-weather in the Mid-Tex Division accounted for $4.5 million of the reduction in gross profit. Atmos Energy’s budgeted earnings for the full 2006 fiscal year reflect 30-year normal weather.

• First quarter results reflect the adverse impact of the effects of Hurricane Katrina on operations in the Louisiana Division, which reduced gross profit by about $2.5 million. As previously disclosed, the company expects a negative impact on gross profit of between $10 million and $12 million for the full 2006 fiscal year.

“In the first quarter, we were able to offset much of the effect on our earnings of unseasonably warm weather with a continued strong performance in our nonutility businesses, especially our natural gas marketing operations, and our continued control of operations and maintenance expenses,” said Robert W. Best, chairman, president and chief executive officer of Atmos Energy Corporation. “Weather in our Mid-Tex Division, which makes up almost 50 percent of our customer base and does not have weather-normalized rates, was 17 percent warmer than normal. We remain focused on seeking rate design that will mitigate the effects of weather, conservation and regulatory lag on our utility margins.”

Consolidated gross profit for the three months ended December 31, 2005 was $346.6 million, compared with $322.1 million in the prior-year quarter. Utility gross profit increased $22.9

million to $280.2 million for the three months ended December 31, 2005, compared with $257.3 million in the prior-year quarter, before intersegment eliminations. Consolidated utility throughput increased to 125.8 billion cubic feet (Bcf) for the three months ended December 31, 2005, compared with 118.9 Bcf for the prior-year quarter. The increases in utility gross profit and throughput primarily reflect weather, as adjusted for jurisdictions with weather-normalized rates that was 7 percent colder than the prior-year quarter. Additionally, the Mississippi Division benefited from an increase in its WNA coverage during the three months ended December 31, 2005, and colder than normal weather prior to the beginning of its WNA period. Offsetting these increases was a reduction in gross profit in the Louisiana Division due to the impact of Hurricane Katrina.

Natural gas marketing gross profit decreased $0.5 million to $26.3 million for the three months ended December 31, 2005, compared with $26.8 million for the three months ended December 31, 2004, before intersegment eliminations. For the fiscal 2006 first quarter, the storage and marketing margin of $26.3 million included a negative $29.5 million mark-to-market impact, which resulted from the change in value of the physical/financial portfolio from September 30, 2005. For the first quarter of fiscal 2005, the storage and marketing margin of $26.8 million included a positive $10.7 million of mark-to-market impact, which resulted from the change in value of the physical/financial portfolio from September 30, 2004. As of December 31, 2005, the physical storage position was 12.8 Bcf with equal and offsetting financial hedges, compared to physical/financial positions of 6.4 Bcf at December 31, 2004. Consolidated natural gas marketing sales volumes were 71.5 Bcf for the three months ended December 31, 2005, compared with 60.3 Bcf in the prior-year quarter.

Pipeline and storage gross profit increased $2.2 million to $39.7 million for the three months ended December 31, 2005, compared with $37.5 million in the prior-year quarter. The increase in pipeline and storage gross profit was primarily attributable to increased throughput on the Atmos Pipeline–Texas system coupled with higher transportation and related services margins.

Consolidated operation and maintenance expense for the three months ended December 31, 2005, was $108.2 million, compared with $110.8 million for the three months ended December 31, 2004. Excluding the provision for doubtful accounts, operation and maintenance expense for the three months ended December 31, 2005, decreased $3.8 million compared with the prior-year quarter. The decrease was primarily attributable to a reduction in third-party costs for outsourced administrative and meter reading functions in the first quarter of fiscal 2005 that were subsequently in-sourced during the first quarter of fiscal 2006, partially offset by a $2.0 million charge for Hurricane Katrina-related losses, increased employee headcount and higher benefit costs. The provision for doubtful accounts increased from $7.5 million for the three months ended December 31, 2004 to $8.7 million for the three months ended December 31, 2005. The $1.2 million increase was primarily attributable to increases in the utility segment provision due to potential increased collection risk associated with higher natural gas prices. In the utility segment, the average cost of natural gas for the three months ended December 31, 2005, was $11.82 per thousand cubic feet (Mcf), compared with $7.22 per Mcf for the prior-year quarter.

Taxes, other than income taxes, for the three months ended December 31, 2005, were $45.4 million, compared with $38.7 million for the prior-year quarter. The $6.7 million increase was primarily related to franchise fees and state gross receipts taxes, both of which are calculated as a percentage of revenue and are paid by utility customers as a component of their monthly bills. Although these amounts are included as a component of revenue in accordance with the company’s tariffs, timing differences between when these amounts are billed to customers and when the company recognizes the associated expense may favorably or unfavorably affect net income on a temporary basis. However, there is no permanent effect on net income.

Interest charges for the three months ended December 31, 2005, were $36.2 million, compared with $32.5 million for the prior-year quarter. The $3.7 million increase was primarily due to higher average outstanding short-term debt balances used to fund natural gas purchases at significantly higher prices, coupled with an increase in the three-month LIBOR rate. These increases were partially offset by $1.2 million in interest savings arising from the early payoff of $72.5 million of the company’s First Mortgage Bonds in June 2005.

For the three months ended December 31, 2005, cash flow generated from operating activities reflected a $195.4 million cash outflow, compared with a $67.9 million cash inflow from operations for the three months ended December 31, 2004. Overall, operating cash flow was adversely impacted by significantly higher natural gas prices, which increased the levels of accounts receivable, natural gas inventories and under-collected deferred gas costs. These increases were partially offset by working capital management efforts which favorably affected the timing of payments for accounts payable and other accrued liabilities.

Capital expenditures increased to $102.5 million for the three months ended December 31, 2005, from $67.2 million for the three months ended December 31, 2004. The $35.3 million increase in capital expenditures primarily reflects increased spending associated with the company’s North Side Loop project in the Dallas/Fort Worth Metroplex and other pipeline expansion projects in the Atmos Pipeline–Texas Division as well as various capital projects in the Mid-Tex Division.

Outlook

Atmos Energy’s leadership remains focused on enhancing shareholder value by delivering consistent earnings growth and providing a sound and attractive dividend. As a result of additional short-term borrowings to fund natural gas purchases and meet working capital requirements during the winter heating season, the debt to capitalization ratio typically reaches its peak at the end of the fiscal first quarter. At December 31, 2005, debt to total capitalization was 61.9 percent. However, Atmos Energy remains committed to reducing the debt to capitalization ratio to a targeted range of 50 to 55 percent within two to four years.

The company believes that despite the continued unseasonably warm weather that is negatively impacting its utility results, natural gas price volatility creates the potential for the complementary nonutility businesses to deliver stronger results, thereby partially offsetting the impact of warmer weather at the utility. As a result, Atmos Energy still anticipates earnings per diluted share in the full 2006 fiscal year to be between $1.80 and $1.90, as previously announced. However, changes in these events or other circumstances that the

company cannot currently anticipate could materially impact earnings, and could result in earnings for fiscal 2006 significantly above or below this outlook.

Highlights and Recent Developments

New Credit Facilities

During the first quarter of fiscal 2006, Atmos Energy renewed and amended its credit facilities to increase its total availability under its committed and uncommitted credit facilities from $893 million to approximately $1.5 billion.

On October 18, 2005, Atmos Energy entered into a $600 million 3-year committed revolving credit facility to replace its $600 million 364-day working capital facility. The credit facility will expire on October 18, 2008. This facility serves as a backup liquidity facility for the company’s commercial paper program. Additionally, on November 10, 2005, Atmos Energy entered into a new $300 million 364-day committed revolving credit facility to supplement amounts available under its existing $18 million committed credit facility and $25 million uncommitted credit facility. The new $600 million and $300 million committed credit facilities contain essentially the same terms as those of the previous $600 million committed credit facility.

On November 28, 2005, Atmos Energy Marketing amended its $250 million uncommitted demand working capital credit facility, primarily to increase the amount of credit available from $250 million to a maximum of $580 million. The credit facility will expire on March 31, 2006. The new credit facility contains essentially the same terms as those of the previous credit facility.
