Burow Kristina 4

What Happened

• Kristina Burow, a director of Scholar Rock Holding Corp. (SRRK), received two equity awards on June 4, 2026: 6,839 restricted stock units (RSUs) and 4,310 derivative units, both reported as grants (transaction code A) at $0.00 per unit (total cash paid $0).
• The RSUs represent a contingent right to receive one share per unit upon vesting; vesting occurs on the earlier of June 15, 2027 or the company’s next Annual Meeting, subject to continued service (see footnote F1). These are compensation awards (not open-market purchases or sales).

Key Details

• Transaction date: 2026-06-04; filing date: 2026-06-08 (filed within normal Form 4 timing).
• Price: $0.00 per unit (awarded, not purchased).
• Reported post-transaction holdings (per filing): 110,871 shares of common stock and 6,839 RSUs (see footnote F2). The filing also records the separate 4,310 derivative-unit grant.
• Institutional/ownership notes: footnotes (F3–F4) indicate many shares are held by ARCH Venture Fund VIII, L.P., with related partnership entities and managers referenced; those entities/managers disclaim beneficial ownership except to the extent of pecuniary interest.
• No indication of a sale or immediate cashless exercise — these are standard equity compensation grants.

Context

• Awards like RSUs are routine compensation and do not necessarily signal an insider buying or selling stock. The derivative units simply mean the right to receive shares at vesting (not current shares).
• For retail investors: watch the vesting schedule (earliest of June 15, 2027 or next Annual Meeting) to know when shares may convert and potentially enter the market.
