Rhea-AI Filing Summary

This Schedule 13G/A reports the beneficial ownership positions of multiple Frazier Life Sciences entities in Lexeo Therapeutics, Inc. common stock and clarifies prior attributions. Frazier Life Sciences Public Fund, L.P. directly holds 3,073,467 shares and related entities hold additional positions including 624,804, 87,424, 232,784 and 406,246 shares across several affiliated funds, with individual percentages reported as high as 5.7% and others at 1.2%, 0.2%, 0.4% and 0.8% respectively.

The filing states these reported share amounts exclude certain warrants and discloses warrant ceilings: FLSPF holds warrants to purchase 2,647,440 shares; FLSPOF 781,005; FLS X 109,280; FLS XI 290,980; and FLS XII 507,809, each subject to a ~9.99% beneficial-ownership exercise limit. The statement explains shared voting and dispositive power structures through general partners and investment committees and corrects any prior over-attribution to individual committee members. The percentage calculations rely on the issuer's reported outstanding shares and shares sold in a public offering as set forth in the filing.

Dieses Schedule 13G/A meldet die wirtschaftlichen Eigentumspositionen mehrerer Frazier Life Sciences-Einheiten an Stammaktien der Lexeo Therapeutics, Inc. und stellt frühere Zuschreibungen klar. Frazier Life Sciences Public Fund, L.P. hält direkt 3,073,467 Aktien und verbundene Gesellschaften halten zusätzliche Positionen in Höhe von 624,804, 87,424, 232,784 und 406,246 Aktien über mehrere angeschlossene Fonds, wobei einzelne Prozentsätze mit bis zu 5.7% und weitere mit 1.2%, 0.2%, 0.4% und 0.8% angegeben werden.

Die Einreichung stellt fest, dass diese gemeldeten Aktienmengen bestimmte Warrants ausschließen und offenbart die Warrant-Obergrenzen: FLSPF hält Warrants zum Erwerb von 2,647,440 Aktien; FLSPOF 781,005; FLS X 109,280; FLS XI 290,980; und FLS XII 507,809, jeweils unterliegt jedes einem Ausübungsgrenzwert von rund ~9.99% des wirtschaftlichen Eigentums. Die Erklärung erläutert die gemeinsamen Strukturen von Stimm- und Verfügungsgewalt über General Partner und Investmentkomitees und korrigiert etwaige frühere Überzuschreibungen auf einzelne Komiteemitglieder. Die Prozentberechnungen basieren auf den vom Emittenten gemeldeten ausstehenden Aktien und den in einem öffentlichen Angebot verkauften Aktien, wie in der Einreichung dargestellt.

Positive
  • Clarifies beneficial ownership of Lexeo Therapeutics shares and corrects prior over-attribution to individual committee members
  • Discloses warrant holdings and exercise limits (e.g., FLSPF warrants for 2,647,440 shares), allowing clearer assessment of potential dilution
Negative
  • None.

Insights

TL;DR: Clarifying a >5% stake and allocation of warrants reduces prior over-attribution and improves disclosure transparency.

The filing provides detailed, corrective disclosure on who holds voting and dispositive power across multiple affiliated Frazier funds. The confirmation that FLSPF directly holds 3,073,467 shares (reported as ~5.7%) is material for investor ownership tables. The explicit exclusion of warrants from reported share counts and the identification of warrant volumes and 9.99% exercise limits is important for modeling potential dilution. This is primarily an informational, transparency-driven update rather than a change in control.

TL;DR: The statement corrects attribution of ownership among investment-committee-managed entities, narrowing individual director/member holdings.

The filing explains governance arrangements: several general partners are managed by investment committees whose members are not being attributed beneficial ownership of fund holdings, and the filing expressly corrects prior attributions. That clarification reduces ambiguity about which individuals exercise voting power over the reported stakes. For governance analysis, the distinction between shared fund-level power and individual member ownership is material to assessing influence but does not indicate any new corporate governance action.
