The effective shelf creates a persistent dilution overhang. Monitor for any takedown announcements or ATM sales, which would accelerate dilution. The cross-filing amplifier (effect-ipo-context + effect-shelf-context) suggests this is a material event; watch for pricing of any offering within 1-2 days.

Executive Summary
Milestone Pharmaceuticals' $300M universal shelf registration (S-3, File No. 333-295860) became effective on May 22, 2026. This allows the company to sell securities, including up to $100M via an ATM facility with Cantor Fitzgerald, creating potential dilution overhang of up to ~44% at current market cap. The shelf is opportunistic to fund commercial launch of CARDAMYST and AFib-RVR development, not distress-driven, given $184.2M cash runway into H2 2027.
