On July 9, 2026, the SEC’s Division of Corporation Finance issued new Corporation Finance Interpretations (CFIs) that clarify the disclosure requirements for campaign-specific activist investment vehicles. The guidance clarifies that investors who fund campaign-specific activist investments through special purpose vehicles, sidecars, or co-investment vehicles may need to be identified in Schedule 13D filings.
Before the SEC’s July 2026 guidance, activist investors generally interpreted Schedule 13D filings as requiring disclosure of the activist vehicle making the investment, not of the underlying investors providing capital to the vehicle. As a result, special purpose vehicles and sidecars have been frequently used to finance individual activist campaigns without requiring public disclosure of those underlying investors in Schedule 13D filings.
Rather than creating a new rule, the SEC sought to clarify how existing Schedule 13D disclosure requirements should be applied to campaign-specific funding arrangements. Question 110.09 of these CFIs focuses on the purpose of the fundraising, whether investors knew the identity of the target company before providing capital, and whether the investment was made through a vehicle established for a specific activist campaign.
One important consideration identified in the new guidance is the purpose of the fundraising. The SEC distinguishes capital raised through a vehicle established specifically to support an activist campaign from capital raised through a broader investment fund. Campaign-specific fundraising arrangements are more likely to require disclosure under Schedule 13D.
The SEC also addresses a situation in which investors knew the identity of the target company before providing capital. When investors commit funds with advance knowledge that the capital will be used to support activism at a particular public company, their identities may be required to be disclosed in Schedule 13D.
The structure of the investment vehicle is another important consideration. Special purpose vehicles (SPVs), sidecars, and other entities formed for a specific activist campaign are more likely to be subject to additional regulatory review than existing investment funds with broader investment objectives. As a result, these campaign-specific structures are more likely to require additional disclosure under the new guidance.
Under the SEC’s interpretation, underlying investors must be disclosed when capital is raised through a separate investment vehicle, such as a special purpose vehicle, that is formed specifically to support an activist campaign targeting a particular public company. Disclosure is generally expected when investors know in advance both the identity of the target company and the specific purpose of their investment, and the investment vehicle proceeds to acquire more than 5% of the company’s outstanding shares, triggering Schedule 13D reporting requirements.
The SEC issued this interpretation to increase transparency in activist investing by providing more visibility into the sources of capital behind activist campaigns. These CFIs are intended to ensure that investors who finance campaign-specific investments are disclosed when required under Schedule 13D, improving transparency around the financing of activist campaigns.
In practice, for activist funds, the interpretation is likely to increase disclosure obligations and require more oversight of campaign-specific fundraising structures. Funds may encounter higher legal and compliance costs, more extensive review of SPVs and other investment vehicles, and additional planning before launching activist campaigns. The increased disclosure requirements may also make it more difficult to raise campaign-specific capital, as some investors may choose not to participate if their identities could become publicly disclosed.
In response to the SEC’s interpretation, activist funds may reconsider how they raise capital and structure investments. Instead of creating campaign-specific SPVs after identifying a target company, some funds may raise capital through broader activist funds before selecting a specific investment. Others may put more emphasis on long-term investment strategies rather than campaign-specific fundraising, depending on their investment objectives and disclosure considerations.
