"% of total stake" is the shares in an event against all the vested shares the person held that day, across every share class and holding entity, after that day's vesting. "n/a" means the person's holdings are not confirmed, or the row is a purchase. "Holdings record incomplete" means more shares were sold than the filings show the person held that day, so a percentage would be wrong.

Outside holders, reported separately

Invus Public Equities, L.P., Srinivas Akkaraju and Kristina Burow reported no open-market sales in the past 12 months. Large shareholders and the funds or companies that board members represent are not part of management, so they are left out of the figures above.

Common questions

Is the Scholar Rock Holding Corp CEO selling stock?

Yes. David Hallal sold 88K shares ($4.0M) in the past 12 months, none of it under a trading plan disclosed in the filings.

Why are Scholar Rock Holding Corp insiders selling?

Filings rarely give a reason, and we don't guess at one. What they show is how the sales were made: 45% of sales by value ran under 10b5-1 trading plans disclosed in the filings and 55% were to cover taxes. A trading plan schedules sales in advance.

Are any Scholar Rock Holding Corp insiders buying?

No. Officers and directors reported no purchases in the past 12 months.

Open-market sales (Form 4 code S) by people who were officers or directors, in split-adjusted shares. Earlier years include people who have since left. A sale that an outside holder also reports (a family trust, a fund) is counted with outside holders in every year. Shares, not dollars, are compared, so a change in the stock price doesn't look like a change in selling. Years the filings don't fully cover are shown but left out of the average.

Holdings and share of stake are being verified. Balances, unit counts and every share-of-stake figure for Scholar Rock Holding Corp are held back until that check is finished. Sales, proceeds, plan and tax status, titles and dates come straight from individual filings and are complete.

External context: we only cite outside events when a documented connection exists. None is shown for this period.

Sources and methodology320 filings on record, 46 filed in the 12-month period, and how we read them

All 320 Forms 3, 4 and 5 on record for Scholar Rock Holding Corp (SEC CIK 1727196), filed from May 23, 2018 to Sep 25, 2026; 46 of them were filed in the 12 months this page covers, retrieved from SEC EDGAR on Oct 16, 2026. Prices are the ones reported in each filing, often weighted averages.

Holdings. Each holding line (a share class plus an owner, such as a trust or LLC) carries its last reported balance forward. Entities first reported during the period start at zero, so transfers between an insider's own trusts don't count as selling. Lines not reported for three years or more are listed separately and left out of totals.

Sales. A sale counts as under a 10b5-1 plan if its footnote cites one or the filing's Rule 10b5-1 box is checked, and as tax-related if its footnote cites tax obligations or sell-to-cover. Shares withheld by the company for taxes are listed separately. Sales with neither attribute are labeled "no plan disclosed".
