How this record is built
Every figure on this page is one figure from a public SEC filing, printed as the filing states it and cited to the document. Compensation totals are INSMED's own disclosed totals, not summed by Velarion. Insider transactions are read from Form 4 filings and cover every line filed since the most recent proxy. Nothing is estimated by Velarion; where the company does not disclose a value the cell reads "—", and a section appears only where the company discloses the data. Corrections: records@velarion.ai.
