Viridian Therapeutics (VRDN)

Companies that benchmark against VRDN
7 companies name VRDN as a compensation peer

Each company listed discloses VRDN in its own benchmarking peer group, as disclosed in each company's most recent proxy statement within the last two proxy seasons. Two companies are therefore absent by design: one that named VRDN in an earlier year and no longer does, and one whose own most recent disclosure is older than the last two seasons.

Equity transactions since the proxy statement was filed

Every insider equity transaction reported on Form 4 after the 2025 proxy statement — acquisitions, dispositions, exercises, and withholdings — and therefore not reflected in any table in that document.

Disclosed peer group — fiscal year 2025

The compensation peer group as the company disclosed it in its own proxy — the reference set behind the percentile above.

10a

Peer reciprocity

Of the companies Viridian Therapeutics names as compensation peers, which name it back in their own disclosed peer groups. A peer set the market reciprocates reads differently from one selected in a single direction.

Reciprocity shown where the peer's own current proxy has been read — each mark is cited in the register to that peer's filing. A dash means the peer's current proxy was read and names no reciprocal group including Viridian Therapeutics.

10b

Chief executive pay against the peer group

Most recent fiscal-year chief executive compensation at each disclosed peer, taken from that company's own proxy statement.
