AI Summary

6.0
Neutral

KNSA is now a profitable, cash-generative specialty-pharma company, but at ~77x earnings and with ARCALYST driving nearly all value, investors should wait for sustained penetration-driven growth or a more attractive entry point while treating KPL-387 as upside optionality—not a proven second engine.
