Atmos Energy Corporation Reports

Solid Results for Fiscal 2004 First Quarter

DALLAS (February 10, 2004)—Atmos Energy Corporation (NYSE: ATO) today reported net income of $29.5 million, or $0.57 per diluted share, for the three months ended December 31, 2003, compared with net income of $25.8 million, or $0.60 per diluted share, for the three months ended December 31, 2002. Results for the fiscal 2004 first quarter represent a 14 percent increase in net income, compared with the same period last year, despite weather that was 12 percent warmer than last year. Earnings per diluted share decreased 5 percent because the company’s average number of diluted shares outstanding rose by 8.9 million shares, or 21 percent, from December 31, 2002, to December 31, 2003.

“Our strategy of combining complementary utility and nonutility operations benefited our shareholders once again this quarter,” said Robert W. Best, chairman, president and chief executive officer of Atmos Energy Corporation. “The strong performance by our nonutility gas marketing segment helped to overcome lower results in our gas utility operations caused largely by unseasonably warm weather.”

“The steps taken by our nonutility operations during the past year to reduce the segment’s risk profile have enhanced its margins,” Best said. “In addition, tariff revisions recently approved in two of our rate jurisdictions will add approximately $8.4 million annually to future revenue. Therefore, we feel confident that Atmos Energy is on track to meet our earlier-announced guidance for fiscal 2004 of earning between $1.55 and $1.60 per diluted share.”

Consolidated gross profit for the three months ended December 31, 2003, was $159.1 million, compared with $137.2 million for the prior-year quarter. Consolidated utility gas throughput for the three months ended December 31, 2003, was 68.2 billion cubic feet (Bcf), compared with 70.9 Bcf for the prior-year quarter. The increase in gross profit primarily reflects the effect of a full three months of results in the current period from the acquisition in December 2002 of Mississippi Valley Gas Company (MVG), compared with one month’s results in the prior-year quarter. Also contributing to gross profit were strong results in the nonutility natural gas marketing segment. These positive factors were partially offset by a decrease in utility throughput attributable to weather that was 12 percent warmer than the prior-year quarter and 5 percent warmer than normal as adjusted for jurisdictions with weather-normalized operations.

Atmos Energy’s net income from nonutility operations, which operate under Atmos Energy Holdings, Inc., was $8.4 million for the three months ended December 31, 2003, compared with net income of $4.7 million for the three months ended December 31, 2002. Nonutility operations

contributed 29 percent of consolidated net income for the 2004 first quarter, compared with 18 percent for the prior-year quarter. Consolidated natural gas marketing sales volumes were 58.9 Bcf for the three months ended December 31, 2003, compared with 59.3 Bcf for the three months ended December 31, 2002.

Nonutility net income was higher in the first quarter of fiscal 2004 primarily due to improved margins and an increase in mark to market gains primarily attributable to the net change in the value of physical storage and corresponding financial hedges.

Operation and maintenance expense for the three months ended December 31, 2003, was $56.9 million, compared with $50.5 million for the three months ended December 31, 2002. Excluding the provision for doubtful accounts and a $6.1 million increase attributable to the acquired MVG assets, operation and maintenance expense for first quarter of fiscal 2004 was slightly lower than operations and maintenance expense for the same period last year. The provision for doubtful accounts was $3.2 million for the three months ended December 31, 2003, compared with $2.9 million for the three months ended December 31, 2002. In the utility segment, the average cost of natural gas for the first quarter of fiscal 2004 was $6.35 per thousand cubic feet (Mcf), compared with $5.03 per Mcf for the first quarter of fiscal 2003.

Taxes, other than income taxes, for the three months ended December 31, 2003, were $15.1 million, compared with $12.8 million for the three months ended December 31, 2002. The increase primarily was attributable to additional franchise, payroll and property taxes associated with the acquired MVG assets and to higher franchise taxes due to higher revenues. Increases in franchise taxes have no effect on net income because these amounts are revenue-based and are recovered through customer billings.

Miscellaneous income for the three months ended December 31, 2003, was $1.2 million, compared with miscellaneous income of $4.1 million for the three months ended December 31, 2002. The $2.9 million decrease primarily reflects the absence in the current-year quarter of a $3.9 million gain recognized in the prior-year quarter associated with a sales-type lease of a distributed electric generation plant and a decrease in year-over-year earnings of $0.5 million from an indirect equity interest in Heritage Propane Partners, L.P. These amounts were partially offset by the favorable effect of the absence of $1.9 million in weather insurance amortization expense in the fiscal 2004 first quarter, resulting from the termination of a weather insurance policy in the third quarter of fiscal 2003.

Interest charges increased $1.9 million during the three months ended December 31, 2003, compared with the three months ended December 31, 2002. The increase was primarily due to interest expense associated with Atmos Energy’s $250.0 million debt offering in January 2003 used to partially finance its MVG acquisition.

For the three months ended December 31, 2003, operating activities provided cash of $11.5 million, compared with a use of cash of $13.4 million for the three months ended December 31, 2002. The year-over-year increase was primarily due to favorable changes in various working capital accounts.
