Burow Kristina 4

What Happened

• Kristina Burow, a director of Scholar Rock Holding Corp (SRRK), exercised multiple option/derivative awards on April 23, 2026 to acquire a total of 89,800 common shares, paying about $820,324 in aggregate. The tranches reported were:
  • 7,800 shares @ $26.78 = $208,884
  • 28,000 shares @ $4.75 = $133,000
  • 36,000 shares @ $9.11 = $327,960
  • 18,000 shares @ $8.36 = $150,480
• The filing also shows corresponding disposals of the derivative instruments at $0, which reflects conversion/exercise of those derivatives into common stock rather than a sale of the shares. No sale of the acquired shares is reported in this Form 4.

Key Details

• Transaction date: April 23, 2026; Form 4 filed April 24, 2026 (timely).
• Total shares acquired: 89,800; total cash paid: $820,324.
• Shares owned after transactions (per filing footnote): 103,239 common shares and 7,632 RSUs.
• Transaction code: M (exercise/conversion of derivative).
• Relevant footnotes note holdings and vesting history of various options/awards; the filing does not indicate a cashless sell-to-cover — payment amounts are shown.

Context

• For retail investors: an option exercise like this increases the insider’s direct share ownership but is not by itself a buy in the open market sentiment sense. Because the filing shows payment of exercise prices (not an immediate sale), Burow added net common shares to her holdings rather than cashing out.
• The Form 4 appears timely (filed the next day), and the disclosure is straightforward: exercised options converted into shares, with no concurrent sales reported.
