Why it may matterVerify against the original reporting

A >$245M verdict is material for a mid-cap like Guardant and could trigger earnings pressure, affecting EPS and cash flow. If broader IP-litigation concerns escalate, multiple sequencing peers (ILMN, PACB) may reprice, impacting sector valuations and potentially the S&P 500, though overall impact remains modest absent broader spillovers.
