GH reported Q3 2026 revenue of $361M, beating estimates by 2.9%, with adjusted EPS of -$0.29, beating by 7.8%. The company raised full-year revenue guidance to $1.37B.

Management expects continued growth from payer coverage expansions and product innovations, with cash flow breakeven targeted by 2027.
