Scholar Rock (SRRK) CHRO Caryn Parlavecchio Sells 6,600 Shares

What Happened Caryn Parlavecchio, Chief Human Resources Officer of Scholar Rock Holding Corp (SRRK), disposed of 6,600 shares on January 16, 2026 at $44.48 per share, for a total of $293,553. The filing reports this was an open market/private sale designated to satisfy tax withholding obligations tied to RSUs that vested on January 15, 2026 — not a discretionary sale.

Key Details

  • Transaction date and price: January 16, 2026; 6,600 shares sold at $44.48 each; proceeds $293,553.
  • Transaction code: S (sale). Footnote F1: sale was a mandatory "sell to cover" directed by the issuer to cover tax withholding on vested RSUs.
  • RSU details: The vested RSUs originated from awards granted on Feb 14, 2022 and Feb 12, 2024; each RSU converts to one share and the shares subject to these awards are fully vested.
  • Ownership after transaction (per filing, Footnote F2): beneficially owns 78,283 shares of common stock and holds 70,581 RSUs.
  • Filing date / period of report: Form filed Jan 21, 2026 reporting the Jan 16, 2026 transaction.

Context This was a routine, issuer-mandated "sell to cover" for tax withholding on vested RSUs, which means it reflects tax logistics rather than a voluntary decision to reduce exposure. Such mandated sales are common following RSU vesting and are different from discretionary insider selling that might signal a change in sentiment.
