Exhibit 99.1 Eagle Rock Energy Partners, L.P. Reports Third Quarter 2006 Financial Results HOUSTON--(BUSINESS WIRE)--Nov. 15, 2006--Eagle Rock Energy Partners, L.P. (Nasdaq:EROC) today reported its financial results for the third quarter ended September 30, 2006. The Partnership reported net income of $12.9 million for the current quarter as compared to a $0.2 million loss for the September 30, 2005 quarter and a $8.9 million loss for the June 30, 2006 quarter. Included in net income for the September 2006 and June 2006 quarters were unrealized risk management activities with a $7.9 million net gain and a $10.8 million net loss, respectively. "We are pleased with our third quarter results, the drilling activity around our assets, the activity level we have experienced with our well connect program, initial benefits of our organic growth programs and the further integration of our recently completed acquisitions," said Alex A. Bucher, Chairman, Chief Executive Officer and President of Eagle Rock Energy. "We continue to move ahead with progress on our organic growth programs as well as other strategic growth initiatives we are exploring." During the quarter, the Partnership was able to amend and restate its credit agreement with commitments of $500 million and the ability to expand the facility up to an additional $100 million by meeting certain financial conditions. As of September 30, 2006, the Partnership had outstanding debt of approximately $397 million with a cash balance of $16.9 million. Segment profit for the current year quarter is $50.9 million as compared to $18.6 million a quarter earlier and $1.1 million for the September 2005 quarter. The increase from the June 2006 quarter comprised of favorable change in unrealized risk management activities recorded in revenues of $29.4 million. The remaining favorable variance of $2.9 million is due to an overall net favorable commodity price environment for the September quarter, higher volume throughput and the full quarter effect of the MGS acquisition. "Looking ahead, we are very active in our organic and strategic growth programs with emphasis on growing our distributable cash flow and financial results," stated Bucher. "We have several initiatives that will impact our performance and cash distribution over the next several quarters. The Tyler Country pipeline extension and Red Deer processing plant start up are targeted organic growth programs with very positive contributions starting in early 2007. We continue to find opportunities in our cost structure and are active on the acquisition front. We feel we have a very strong level of stable cash flow from the mixture of our gas gathering and processing activities and contracts, downside protection from our risk management program, a healthy balance sheet and borrowing capacity within our credit agreement to facilitate future growth programs." Adjusted EBITDA for the current quarter was $24.2 million as compared to $63,000 for the September 2005 quarter and $21 million for the June 2006 quarter. The increase in Adjusted EBITDA from June reflects the impact from favorable commodity pricing environment during the September quarter, continued contribution from the Tyler County pipeline, well connect activities and the full quarter impact of the MGS acquisition. On November 10 and 14, the Partnership respectively declared and paid a distribution of $14.3 million to both common and subordinated unitholders of record as of September 30, 2006. The distribution was from September 30, 2006 quarter cash flow. The Partnership completed its initial public offering on October 24, 2006, issuing 12,500,000 common units to the public, representing approximately a 30% limited partner interest. "I want to thank the employees of Eagle Rock for their hard work and contribution over the past year, they are the key reason for our success. Our safety and environmental record continues to be excellent while handling the new challenges that come with growth," expressed Bucher.
