Kim Jean Jinsun 4

What Happened
Director Kim Jean Jinsun disposed of a total of 104,215 shares and option-equivalents on 2026-02-27 pursuant to Avidity’s Merger Agreement with Novartis. The merger consideration was $72.00 per share. The reported disposals include 6,692 shares of common stock (including RSUs) and 97,523 derivative units (options and/or other derivatives). Common stock/RSUs were exchanged at $72 per share; reported options were cashed out for the difference between the $72 merger price and each option’s exercise price. If every unit were paid at $72 the notional amount would be about $7.50 million, though actual option payouts equal only the spread over strike prices.
