Reasoning
The upside case is driven by mix and embedment, not just more tests. If oncology becomes a larger share of revenue, more Signatera volume moves into covered buckets, and Natera adds companion-diagnostic, pathway, and workflow economics, the business can keep compounding well above ordinary diagnostics. I still assume some multiple compression as the company matures, but not all the way to commodity-lab levels because the oncology franchise is evidence-led, data-rich, and increasingly cash generative.
