Larry Robbins, a director at Butterfly Network, Inc. ($BFLY), reported the sale of 156,163 shares of company stock on August 3, 2026, according to a Form 4 filed with the Securities and Exchange Commission. The shares were sold in an open-market transaction at an average price of $8.10 per share, yielding total proceeds of approximately $1.27 million. The filing was submitted the same day as the trade. After the transaction, Robbins held 12,458,763 shares.
Three days earlier, on July 31, Robbins sold 1,720,129 shares at an average price of $7.39 per share, generating proceeds of approximately $12.72 million. That trade was disclosed on the same August 3 Form 4, representing a three-day gap between execution and reporting. Together, the two dispositions amounted to 1,876,292 shares sold for combined proceeds of roughly $13.98 million.
Robbins was not the only Butterfly Network insider selling shares during the July-to-August window. Founder Jonathan M. Rothberg executed three open-market sales between July 17 and July 21, disposing of a combined 3,126,453 shares. The transactions broke down as 1,195,857 shares at $6.60 on July 17, 1,177,276 shares at $6.61 on July 20, and 753,320 shares at $6.74 on July 21. The aggregate proceeds from Rothberg's three sales totaled approximately $20.74 million.
Other insider selling during the same stretch included two transactions by Joseph Devivo — 204,725 shares at $7.87 on July 7 and 211,798 shares at $6.56 on July 20 — along with a sale of 57,136 shares by John N. Doherty on July 20 at $6.56, and a sale of 35,649 shares by Victor Ku on July 7 at $7.87. In total, at least five Butterfly Network insiders reported open-market sales between July 7 and August 3.
The recent sales occurred at prices well above the levels at which Robbins accumulated his position in late 2025. Between November 19 and December 11, 2025, Robbins executed seven open-market purchases of Butterfly Network stock totaling 4,379,911 shares. Those purchases were made at prices ranging from $2.35 to $3.06 per share, with an aggregate acquisition cost of approximately $11.5 million. At the time of the August 3 sale, Robbins' remaining stake of 12.46 million shares reflected a position built principally during that late-2025 buying period.
Butterfly Network, a health care sector company specializing in medical imaging technology, had a market capitalization of approximately $1.86 billion at the time of the filing. The stock closed at $7.11 on July 31, the date of Robbins' larger sale.
