Beneficial Ownership: Key Insights from the CA100 Section 21(a) Report

Liz recently blogged about the SEC’s recent Section 21(a) report addressing the actions of certain members of Climate Action 100+ (“CA100”) during the 2021 proxy contest targeting Exxon Mobil. This Cooley memo highlights some of the key insights to be drawn from that report:

– No enforcement action, but a clear warning. The SEC’s investigation raised serious concerns, and the SEC used the report to provide guidance for investors participating in similar organizations. Coordinated action prompted by an intermediary’s pressure on members to align regarding the acquisition, holding, disposition or voting of securities may provide circumstantial evidence of an agreement or understanding sufficient to create a “group” as determined under Sections 13(d)(3) and 13(g)(3).

– Disclaimers alone are not enough. Investors may reserve independent voting discretion and disclaim “group” status, but the SEC emphasized that actual conduct controls. At the same time, parallel voting, ordinary-course communications, independent voting decisions and passive receipt of an activist solicitation do not, standing alone, establish a “group.”

– Schedule 13G eligibility presents a separate risk. Even if investors have not formed a “group,” a qualified institutional investor or passive investor holding more than 5% may lose eligibility to report on Schedule 13G if its activities have the purpose or effect of changing or influencing control of the issuer. The report suggests that this analysis can extend beyond a director contest to coordinated efforts targeting specific management or policy outcomes.

– Proxy advisers are a natural area to watch. The report repeatedly focuses on intermediaries that organize investors around shared objectives and voting outcomes. That framework closely tracks the December 2025 executive order, which specifically directed the SEC to consider whether a proxy adviser can facilitate coordination among investment advisers sufficient to create a “group” as determined under Sections 13(d)(3) and 13(g)(3).

We’re posting memos in our “Schedule 13D & 13G” Practice Area.
