Why is Labcorp stock sliding today?
Labcorp (LH) stock fell 3.4% after-hours to $310 following CMS's proposal to cut Medicare lab reimbursements by up to 15% annually starting 2027. CMS claims this corrects overpayments, potentially saving $1B yearly. Truist raised its price target to $365 but kept a Buy rating. Quest Diagnostics faces similar headwinds. The selloff was sector-specific, with broader markets flat.
