SCHEDULE 13G/A
Frazier-affiliated funds disclose their holdings in Disc Medicine (Common Stock, CUSIP 254604101). The largest single holding reported is 1,026,489 shares (3.0% of the class) held directly by Frazier Life Sciences Public Fund, L.P., with shared voting and dispositive power. Other direct holdings include 300,643 shares (0.9%) by Frazier Life Sciences Public Overage Fund, L.P., 264,484 shares (0.8%) by Frazier Life Sciences XI, L.P., and 63,218 shares (0.2%) by Frazier Life Sciences X, L.P.
The filing clarifies governance and attribution: several entities report shared voting and shared dispositive power over these positions and the Statement corrects any prior over-attribution of ownership to certain committee members. Percentages are calculated using 34,634,295 shares outstanding as stated in the filing.
Positive
- Clarification and correction of prior attributions reduces overstated beneficial ownership for individual committee members
- Detailed disclosure of shared voting and dispositive power provides clearer governance transparency
Negative
- None.
Insights
TL;DR Frazier entities hold small, non-control stakes (all below 5%), and the filing clarifies prior attribution errors.
The largest reported position is 1,026,489 shares (3.0%) held by Frazier Life Sciences Public Fund, L.P., with other Frazier funds holding between 0.2% and 0.9%. All reported holdings are stated as shared voting and dispositive power for the listed entities where applicable. The filing also explicitly corrects prior attributions to individual committee members, reducing previous overstatements of beneficial ownership. Given each position is below the 5% reporting threshold for control implications, the disclosure is primarily informational and governance-clarifying rather than indicative of control or a coordinated group.
TL;DR The filing emphasizes accurate attribution of voting and dispositive power and denies group formation for control purposes.
The Statement clarifies that general partners and investment committees for several Frazier entities manage the funds and that members of those committees are not to be attributed beneficial ownership of the funds' holdings. Reporting Persons state that the filing should not be construed as an admission of beneficial ownership under Sections 13(d)/(g) or as forming a group. These formal clarifications matter for governance and proxy contexts because they limit individual attribution of fund-held shares and correct previously overstated ownership positions.
