Why Labcorp Holdings Stock Dropped Today

Labcorp Holdings stock fell 3.3% after the Centers for Medicare & Medicaid Services announced plans to reduce lab testing reimbursement rates by 15% starting next year, with potential additional cuts through 2029. Since CMS accounts for approximately 8% of Labcorp's revenue, a full 15% reduction would decrease annual revenue by 1.2%, with a worst-case scenario of 3.6% reduction if cuts continue through 2029. The stock's decline appears to have already priced in this worst-case scenario.
