Guardant Health posts strong Q3 revenue growth but raises full‑year cash‑burn outlook

Guardant Health reported third‑quarter 2026 revenue of $360.98 million, up 36.1% year over year, while its net loss widened to $124.36 million. The company lifted its full‑year revenue guidance to $1.36 billion‑$1.37 billion and increased its free‑cash‑flow burn outlook to $205 million‑$220 million. Despite the earnings beat, the stock slipped about 5.5% in after‑hours trading.

The higher cash‑burn forecast signals greater spending to scale commercial operations, which may pressure cash runway and affect investor sentiment, as reflected by the share‑price decline (the company notes the market reaction to the burn guidance).
