Guardant Health (GH) Q4'25 Earnings Call

Financial quality
The sleeper story is Shield's economics converging on Cologuard's profitability while maintaining superior adherence, potentially creating an unassailable competitive moat in blood-based screening. The obvious revenue beat and strong 2026 guidance mask a more concerning deceleration in G360 volume growth from 40% to 38% and management's regression from 'more than 30%' to 'nearly 30%' language. The binding constraint isn't demand but execution - Shield's commercial payer contracting speed will determine ASP sustainability, while G360's plateau risk emerges despite Smart apps supposedly driving adoption. Most revealing quote: 'We are not counting any kind of contribution from Quest co-promotion' - a notable walk-back from Q3's bullish positioning. My view changes if G360 liquid growth drops below 25% or Shield ASP falls below $750, signaling either market saturation or reimbursement challenges.
