Quest Diagnostics posts Q3 2026 results, raises full‑year revenue and EPS outlook

Quest Diagnostics reported third‑quarter 2026 revenue of about $3.10 billion, a 10% year‑over‑year increase, and adjusted earnings per share of $3.00, up 15.4% from the prior year. The company lifted its full‑year 2026 revenue guidance to a range of $12.065 billion‑$12.105 billion and its adjusted EPS guidance to $11.25‑$11.35. Management highlighted strong volume growth, new Apple Health app lab ordering, and an upcoming acquisition of outreach lab assets, while noting a potential 1% revenue headwind from PAMA reimbursement changes in 2027.

The raised guidance signals higher expected earnings and cash flow for the year, which may support a higher valuation for DGX. Management also warned that PAMA reimbursement cuts could reduce 2027 revenue by roughly 1%, a risk investors should consider.
