As CEO of Cost Plus Drug Co., Mark Cuban is telling other CEOs: “If the big 3 PBMs, which also own the insurance companies, lose 5 of the top 15 non-PBM Fortune 50 companies, their business practices are going to change.”

Many people know Mark Cuban as one of the “sharks” on the ABC-TV show “Shark Tank” – and the colorful owner of the Dallas Mavericks basketball team. But he also is a successful entrepreneur who understands the importance of controlling costs.

“As a CEO, when I finally realized that my sickest employees were subsidizing this rebate check I was getting, it made me sick to my stomach,” Cuban said on the recent “Relentless Health Value” podcast. “And that’s what I’m here to tell CEOs of self-insured companies and CFOs and HR people.”
