DUBLIN - Investment firm Citadel Group has disclosed a 2.33% ownership position in Mural Oncology plc, according to a regulatory filing released Friday.

The disclosure, made under Irish Takeover Panel rules, shows Citadel holds 403,916 shares representing a long position in the biopharmaceutical company, alongside a short position of 212,823 shares, equivalent to 1.22% of outstanding stock.

The filing details that Citadel’s position includes 375,816 directly owned shares and additional exposure through stock-settled derivatives. The disclosure also documents multiple transactions conducted on August 21, with Citadel both purchasing and selling Mural Oncology shares at prices ranging from $2.07 to $2.09 per share.
