Aug 7 Duke Energy Corp, the largest electricity provider in the United States, posted a 64 percent jump in quarterly revenue, helped in part by its buyout last year of a key rival, but earnings fell.
For the second quarter, the company posted net income of $339 million, or 48 cents per share, compared with $444 million, or 99 cents per share, in the year-ago period.
The company's 2012 buyout of rival Progress Energy substantially increased the company's float.
Operating revenue rose to $5.88 billion from $3.58 billion.
Duke said it still expects to earn $4.20 to $4.45 per share this year.
