Insights

Securities Analyst

TL;DR: A prominent investment adviser discloses an 8.4% passive stake, with sole voting and dispositive control over the shares held by its funds.

The filing shows Baker Bros. Advisors (and its GP and principals) exercises sole voting and dispositive authority over 10,168,901 shares of Immatics, equal to 8.4% of the reported outstanding stock. The stake is concentrated in two funds with clear allocation between them (9.35M and 0.81M). For investors, this disclosure clarifies ownership structure and confirms the adviser’s control over votes and dispositions of the reported shares, consistent with prior Schedule 13G filings.

Corporate Governance Expert

TL;DR: The amendment documents centralized authority within the adviser structure and identifies controlling persons for shareholder voting.

The amendment highlights that the funds’ general partners relinquished discretion to the adviser, making the adviser the sole decision-maker for these holdings; the GP and two individuals are disclosed as related reporting persons. This structure is important for governance transparency because it identifies who can direct voting on corporate matters and confirms the passive-status filing framework under Rule 13d-1.
