Brown Kimberly 4

What Happened

• Kimberly Brown, Chief Accounting Officer of Lantheus Holdings (LNTH), was granted 6,158 stock units on March 5, 2026 (reported March 9, 2026). The grant is reported as an award/acquisition (code A) with a $0.00 per-share price because these are restricted/performance-based units.
• On the same date, 133 shares were disposed (code F) to satisfy tax withholding at a price of $76.31 per share, totaling approximately $10,149.

Key Details

• Transaction date: 2026-03-05; filing date: 2026-03-09 (filed within the Form 4 reporting window).
• Award: 6,158 shares reported as acquired at $0.00 (codes A).
• Tax withholding: 133 shares withheld/settled at $76.31/share = $10,149 (code F, “Payment of exercise price or tax liability”).
• Shares owned after the transactions: not specified in this filing.
• Footnote: The 6,158 units consist of 3,079 time-based restricted stock units (vesting in equal installments over three years) and 3,079 Total Shareholder Return performance-based RSUs (PSUs) that cliff vest after a three‑year performance period. PSU payout is target-based and may range from 0% to 200% of target.

Context

• The acquisition is an equity award (not an open-market purchase) and thus is part of routine executive compensation rather than a cash investment signal.
• The 133-share disposition represents share withholding to cover taxes upon grant/vesting, a common administrative step when RSUs/PSUs are issued.
• PSUs are performance-contingent: actual shares earned at the end of the performance period could be lower or higher than the target (0–200%).
