What happened

IDEXX Laboratories (IDXX) stock jumped about 20% to above $660 on Monday after the pet diagnostics maker beat third-quarter earnings and sales estimates and raised its 2026 forecast. Sales rose 10% from a year ago to $1.21 billion, and profit per share was $3.96 after adjusting for one-time items, above the roughly $3.72 analysts expected. Repeat lab and test revenue from pets (recurring revenue) grew 11%, and IDEXX lifted its full-year outlook (guidance). Some outlets put the day's gain nearer 22%, depending on the price used.

Why it matters

IDEXX makes the lab machines and tests that vets use to check pets' health, so its results show how much pet owners are still spending on care. The strong report suggests testing demand held up even though U.S. vet clinic visits fell an estimated 1.8%. IDEXX is part of the S&P 500, so a move this big also touches many index funds.
