Insights

Large warrant exercise shifts a 10% holder from derivatives into common stock.

The filing shows a 10% shareholder group affiliated with Invus Global Management, LLC exercising a warrant for 1,575,008 Scholar Rock common shares at $7.35 per share. The corresponding derivative position, a warrant originally covering the same share amount, now shows 0 derivative securities remaining.

Post-transaction, the group directly holds 10,825,013 common shares, consolidating exposure into the underlying equity instead of the warrant. A control chain from Invus Public Equities, L.P. through Invus Global Management and Siren, L.L.C. to Mr. Raymond Debbane is described, with each reporting person disclaiming beneficial ownership of others’ holdings beyond their pecuniary interest.

This is characterized as a change in form of beneficial ownership (code X), rather than a simple open-market buy or sale. Actual impact on ownership dynamics depends on overall shares outstanding and future trading decisions by these entities, which are not detailed in the excerpt.
