Hallal David 4

What Happened

• David Hallal, Chief Executive Officer of Scholar Rock Holding Corp (SRRK), was granted 128,004 restricted stock units (RSUs) on February 9, 2026. The award was reported on Form 4 and shows an acquisition price of $0.00, so there is no immediate cash value to the grant.
• The RSUs are time‑based and will convert into one share per RSU upon vesting (see vesting schedule below). This is an equity grant (award), not an open‑market purchase or sale.

Context

• RSU grants are compensation awards that vest over time; they do not involve an immediate cash outlay by the insider and do not equate to an open‑market purchase or sale. Such awards are common for executive compensation and are primarily tied to retention and, in some cases, performance metrics (this grant is time‑based).
• For retail investors: awards increase potential future share supply when vested shares are issued, but by themselves do not indicate immediate insider buying or selling intent.
