Piedmont Reports Third Quarter Results
CHARLOTTE, N.C., September 2 /PRNewswire-FirstCall/ — Charlotte-based Piedmont Natural Gas (NYSE: PNY) announced results for its third fiscal quarter ended July 31, 2005. For the quarter, the Company reported a seasonal loss of $4.7 million and ($0.06) per diluted share, compared with an $8.2 million loss and ($0.11) per diluted share for the same quarter in 2004.

For the nine months ended July 31, 2005, net income was $106.2 million and diluted earnings per share were $1.38, compared with $107.7 million and $1.46 for the prior nine-month period. Earnings in the prior year nine-month period include $4.6 million, or $.06 per diluted share, of one-time joint venture gains that were reported in the first quarter.

Margin in the third quarter increased compared with the prior year’s quarter primarily due to higher consumption in the residential and commercial markets because of colder weather in May, improved results in the large volume market and in secondary market margins. Operations and maintenance expenses increased from the prior-year quarter primarily due to higher employee benefit, payroll and uncollectible expenses. General taxes increased primarily due to higher payroll and property taxes.

Other income, net of income taxes, was $3.8 million for the quarter, compared with $3.1 million for the same quarter of the prior year. The Company’s interest in SouthStar Energy Services LLC, which is primarily engaged in the unregulated retail natural gas market in Georgia, contributed $1.6 million to net income or $0.02 per diluted share in the third quarters of both the current and prior years. Two other joint ventures, Pine Needle LNG and Cardinal Pipeline, contributed combined diluted earnings per share of $0.01 in the third quarters of both the current and prior years.

At the Company’s regular quarterly meeting of its Board of Directors held today, a quarterly dividend on Common Stock of 23 cents per share was declared, payable October 14, 2005, to holders of record at the close of business on September 23, 2005.

Piedmont Natural Gas reaffirms its guidance for fiscal year 2005 earnings from continuing operations in the range of $1.23 to $1.30 per diluted share. Guidance reflects actual results for the first nine months of fiscal year 2005 and expected performance for the balance of the year assuming normal weather.
