Penner Sports Group, the investment vehicle of Denver Broncos owners Greg Penner and Carrie Walton Penner, has acquired an approximately 40% minority stake in the Colorado Rockies, making it the largest minority partner in the MLB franchise. The deal, announced by Rockies chairman and CEO Dick Monfort and approved by Major League Baseball, allows the club to retire all outstanding debt and fund improvements to Coors Field. Dick and Charlie Monfort will retain their leadership roles, with Walker Monfort continuing as team president. Forbes has valued the Rockies at $1.68 billion. The Penners emphasized that their primary focus remains the Broncos, but expressed commitment to being long-term partners of the Rockies and Major League Baseball.
