Jana Partners Continues Buying Houston Exploration (THX) After Offer Shot Down

In an amended 13D filing on Houston Exploration Co. (NYSE: THX) after the close Monday, Jana Partners disclosed a 14.8% stake (4.1 million shares) in the company. This is up from the 12.8% stake (3.7 million shares) the firm disclosed in a past filing.

On June 12, the hedge fund sent a letter to Houston Exploration's Board proposing to purchase the Company for $62 per share. In response to the offer, Houston Exploration's board said the unsolicited offer from JANA Partners was not in the best interest of its shareholders.
