AI Summary

6.0
Neutral

ILMN is now a high-expectations execution story rather than a simple turnaround: maintain or add exposure only if mid-single-digit organic growth and free-cash-flow margins stabilize, as its premium valuation and leverage leave little room for margin erosion or weaker demand.
