Exhibit 99.1 Eagle Rock Energy Partners, L.P. Reports Results for Fourth Quarter and Full Year 2006 HOUSTON--(BUSINESS WIRE)--April 2, 2007--Eagle Rock Energy Partners, L.P. (Nasdaq:EROC) today reported its financial results for the fourth quarter and full year ended December 31, 2006. For the fourth quarter of 2006, the Partnership reported $115.7 million of revenues as compared to $57.4 million for the fourth quarter of 2005. Total revenues for the year ended December 31, 2006 were $478.4 million as compared to total revenues of $73.7 million for the year ended December 31, 2005. The Partnership reported a net loss of $11.7 million for the fourth quarter of 2006, compared to net income of $3.2 million for the same period in 2005. Net loss for the fourth quarter of 2006 included a $4.8 million net loss for unrealized risk management activities as compared to an $8.9 million net gain for the fourth quarter of 2005. Additionally, during the fourth quarter of 2006, the Partnership recorded a pre-tax $6.0 million expense related to the termination of an advisory services agreement, which contributed to the net loss reported. Net loss for the year ended December 31, 2006 was $23.3 million as compared to net income of $2.7 million for the year ended December 31, 2005. Included in net loss for 2006 was $23.5 million net loss of unrealized risk management activities as compared to $8.9 million of net gains for unrealized risk management activities in 2005, in addition to the pre-tax expense attributable to the $6.0 million expense related to the termination of an advisory services agreement. Adjusted EBITDA for the fourth quarter of 2006 was $19.0 million, which was in the guidance range the Partnership reported earlier. For the fourth quarter of 2005, adjusted EBITDA was $3.1 million. Adjusted EBITDA for the year ended December 31, 2006 was $81.2 million as compared to $3.4 million for the year ended December 31, 2005. The increase in revenues and adjusted EBITDA for the fourth quarter of 2006 as compared to the previous year's fourth quarter reflects the impact from a full quarter inclusion of the Panhandle Texas acquisition (assets acquired December 1, 2005) and the Brookeland and MGS acquisitions during 2006. The improvement in results also reflects the impact of the organic growth projects during the year including the first phase of the Tyler County Pipeline project, as well as the growth from the well attachment programs during the year. The Partnership also announced the filing of its Annual Statement on Form 10-K for the year ended December 31, 2006 with the Securities and Exchange Commission. Eagle Rock will host a conference call to discuss financial results and the previously announced potential acquisitions, financing and organizational changes on Wednesday, April 4, 2007, at 9 a.m. CT (10 a.m. ET).
