AI Summary

5.0
Neutral

ALKS is now an acquisition-driven, leveraged execution story rather than a straightforward profitable neuroscience play: investors should wait for margin and EBITDA recovery toward 2026 guidance to validate that Lumryz/Avadel benefits and alixorexton upside can support $1.57B of debt, as weak interest coverage leaves little room for delays.
