Killer combo: Material agreement + unregistered equity (likely PIPE/convertible)
Actionable Insight • Neutral

Monitor for use of proceeds toward pipeline catalysts (revumenib, entinostat) and any subsequent equity issuances that could accelerate dilution. The convertible structure provides a low-cost financing source (2.25% coupon) but creates overhang given the conversion premium. Watch for any fundamental change events that could trigger note repurchase rights.
