Soroban Capital Partners reported a 16,357,600 share stake in Petrohawk Energy Corporation (NYSE:HK) through a Schedule 13G filed on April 11, 2011. The stake is 5.4% of shares outstanding and it makes Soroban Capital the natural gas company's largest shareholder. Based on Petrohawk's current price of $22.85, the position has a notional value of $373.77 million.
Soroban Capital Partners launched in November 2010 and has around $1.1 billion under management. We do not know what kind of leverage the firm employs and what positions they may have offsetting the long position, but the $373.77 million position is HUGE relative to the reported assets under management. Petrohawk Energy has often been mentioned as a possible acquisition target. It will be interesting to see how this investment develops.
Soroban is headed by Eric Mandelblatt who started at Goldman Sachs (NYSE:GS) in 1998 as an energy analyst. He later worked for the firm's principal strategies group as the chief operating officer. In 2005, Mandelblatt worked with former Goldman alum at TPG-Axon Capital Management LP. Mandelblatt is running Soroban with other TPG alum, Scott Friedman and Gaurav Kapdia.
