F1	The transaction reported in this Form 4 reflects additional shares of common stock issued by Lantheus Holdings, Inc. ("LNTH") to the reporting person upon the vesting of relative Total Shareholder Return performance-based restricted stock units ("PSUs") that were previously granted and included in the Form 4 filed on March 7, 2022. The number of shares reported in the Form 4 reflected 100% of the target number of shares underlying the PSUs.
