SEC Mandates Activist Investors Disclose Client Identities in Filings

The U.S. Securities and Exchange Commission (SEC) has clarified its rules to require activist investors to disclose the identities of their clients in key regulatory filings. The unexpected update signals a push for greater transparency in a corner of the market where anonymity has long been standard practice.

New Disclosure Guidance

The SEC issued the new requirements through updated interpretations of its rules for 13D filings and proxy statements. According to lawyers cited by Reuters, the move was not widely anticipated. The guidance specifically targets entities created to acquire a company's securities and launch an activist campaign.

Two key clarifications were made:

• Question 110.09 states that the "identities of the investors in an entity formed for the purpose of acquiring securities of a specific issuer and engaging in an activism campaign" must be disclosed.
• Question 155.02 clarifies that clients of a limited partnership are considered "participants" in a proxy solicitation if they invested more than $500.

Impact on Activist Investing

The new interpretation directly affects the growing use of special purpose vehicles, often called "sidecars," which allow a fund's clients to invest in a specific campaign rather than the main fund. Hedge funds have historically argued that keeping the identity of their investors, or limited partners, confidential is crucial to protect their strategies from copycats and maintain a competitive edge.

Conversely, companies targeted by activists have argued that knowing who is funding a campaign is necessary information to mount a proper defense and engage with shareholders. This SEC guidance could shift the balance of power by providing corporate boards with more information about the investors seeking to influence their companies.

Context and Precedent

The SEC's move comes amid a busy year for shareholder activism, with firms like Elliott Investment Management and Ancora Alternatives launching campaigns at major companies such as Warner Bros Discovery and Devon Energy.

The debate over investor disclosure is not new. In 2022, medical device firm Masimo Corp amended its bylaws to force activist Politan Capital to disclose its limited partners. The move sparked an outcry from the activist community, and while hundreds of companies reportedly considered similar measures, Masimo eventually reversed the policy in early 2023.
