Butterfly Network Founder Rothberg Sells Another 660,000 Shares. Should Investors Worry?

Butterfly Network founder Jonathan Rothberg sold approximately 660,000 shares (~$4.3 million) on July 22, 2026, under a pre-scheduled Rule 10b5-1 trading plan for estate planning purposes. While the sale was pre-planned, analysts note it's concerning timing given the stock's 250% surge over the past year and multiple recent insider sales. Despite positive analyst outlooks for 2026 revenue growth of 22%, investors are advised to reconsider their investment thesis given the founder's share liquidation near five-year highs.
