Chesapeake Energy Corporation has been named to Forbes' Platinum 400 list of America Best Big Companies and was further identified as the best managed company in the Oil & Gas Operations category in the magazine's January 8, 2007 issue. Chesapeake ranked 34th on the Platinum 400 list based on its 40% five-year total return as computed by Forbes. In addition, Forbes complimented the company leadership for "their knack for snapping up promising acreage."

The Platinum 400 list was compiled from over 1,000 corporations having at least $1 billion in revenue in the most recent fiscal year and included both American and foreign corporations that have a significant presence in the U.S. Companies were then assigned to 26 industries and ranked against their peers not only for financial performance but also for leadership, innovation and execution. The ranking system also included consensus forecasts for long-term earnings growth and debt to capital ratios. Using these individual rankings, Forbes gave each company a composite score and an overall rank within its industry.
