$IRONForm 424B5Filed Oct 19, 2026, 5:42 PM ET0001193125-26-425425Original filing

Disc Medicine filed a 424B5 prospectus supplement for a $350 million underwritten offering of common stock and pre-funded warrants, priced one day after announcing positive topline results from the pivotal Phase 3 APOLLO trial of bitopertin in erythropoietic protoporphyria (EPP), which met all primary and secondary endpoints. Jefferies, Leerink, Morgan Stanley, and Cantor are joint book-running managers, with a 30-day option to purchase up to an additional $52.5 million of shares. IRON's closing price on October 19, 2026 was $78.93, and the offering follows an earlier CRL on the bitopertin NDA that the APOLLO data are intended to overcome.
