$IRONForm 424B5Filed Oct 21, 2026, 5:21 PM ET0001193125-26-427982Original filing

Disc Medicine priced a $450 million follow-on offering of 6 million shares at $75.00, a roughly 5.6% discount to the prior close of $79.48, with a 900,000-share greenshoe and net proceeds of about $422.4 million. The raise comes just two days after positive APOLLO Phase 3 topline results for bitopertin in erythropoietic protoporphyria, which met all primary and secondary endpoints; the company plans to resubmit its NDA by end of 2026 with an FDA decision anticipated by mid-2027.
