Wisconsin Energy posts first quarter results

MILWAUKEE - Wisconsin Energy (NYSE: WEC) today reported net income from continuing operations of $176.6 million or 76 cents a share for the first quarter of 2013. This compares with net income from continuing operations of $172.1 million or 74 cents a share for the first quarter of 2012.

First quarter 2013 revenues were $1.28 billion. In the corresponding quarter a year ago, revenues totaled $1.19 billion.

Cold winter temperatures in the first quarter of 2013 compared to warmer than normal conditions last year drove strong customer demand for natural gas and higher revenues than the company recorded in the first quarter of 2012.

In addition to the weather, slightly higher earnings at We Power and the impact of the company's share repurchase program were major factors in the positive first quarter performance.

Residential use of electricity rose by 5.2 percent over last year's first quarter. Consumption of electricity by small commercial and industrial customers grew by 1.3 percent. Electricity use by large commercial and industrial customers was down 3.9 percent - in line with the company's expectations.

At the end of March, the company was serving approximately 3,000 more electric customers and 6,000 more natural gas customers than a year ago.

“We performed well - operationally and financially - in the first quarter. The year is off to a solid start, and overall, we're very pleased with our results,” said Gale Klappa, chairman, president and chief executive officer.

“We're reaffirming our earnings guidance for calendar year 2013 in the range of $2.38 to $2.48 a share,” he said.

Earnings per share listed in this news release are on a fully diluted basis.
