The New York Mercantile Exchange owner is planning a public offering that could be valued to more than $1 billion.
Nymex filed with the Securities and Exchange Commission Friday to sell an undisclosed amount of common stock. The proceeds are said to be intended for general corporate purposes.
Nymex became the biggest debut gainer when it went public in November 2006, raising $384 million. Nymex members were told in November that they could sell part of their stakes this spring, but the company’s board decided Thursday to let a sale, known as a secondary offering, take place sooner.
Part of the reason behind the decision is because Nymex stock has done so well in the market, trading as high as $152 from an initial price of $59 a share.
