FLIER JEFFREY S. 4

What Happened
Jeffrey S. Flier, a director of Scholar Rock Holding Corp. (SRRK), was granted equity awards on June 4, 2026. The Form 4 reports 6,839 restricted stock units (RSUs) and an additional 4,310 RSUs (reported as a derivative award) were acquired with a reported price of $0.00 (typical for stock awards). These were awards (transaction code A), not open-market purchases or sales, so no cash changed hands at grant.

Context
RSU grants are standard compensation for directors and reflect compensation decisions by the company rather than an insider buying or selling stock. Because these are awards subject to future vesting conditions, they do not immediately increase Flier’s voting shares until vested and converted to common stock. For investors, awards are informative about how the company compensates leadership but are not the same signal as an insider purchase or sale.
