CFI 155.02 establishes a bright-line threshold: any investor that contributes more than $500 to an entity formed specifically to finance a proxy solicitation at a particular company is a participant in that solicitation under Schedule 14A and must be disclosed. Combined with CFIs 110.09 and 110.10 from the same package, which imposed analogous disclosure requirements for Schedule 13D, the July 9 CFIs collectively increase the transparency of activist campaign financing structures in a way that materially changes both the activist's disclosure obligations and the corporate defence team's ability to identify the real principals behind a campaign.
This post covers what a proxy solicitation participant is, what CFI 155.02 specifically says, what the $500 threshold means operationally, what information must be disclosed about each investor, what this changes for activist campaign structures, and what corporate defence and IR teams must update in their monitoring playbooks.
What Is a "Participant" in a Proxy Solicitation Under Schedule 14A?
Schedule 14A is the form used to make proxy solicitations under the Exchange Act. When a company or any other person solicits proxies from shareholders, they are required to provide the solicited shareholders with a proxy statement that discloses material information about the solicitation and the persons conducting it.
The concept of a participant in a proxy solicitation is defined in Instruction 3 of Item 4 of Schedule 14A and elaborated in Rule 14a-2. A participant includes any person on whose behalf a proxy solicitation is made, any person who directly or indirectly solicits proxies on behalf of the filing party, any committee or group formed to solicit proxies, and any person who finances or organises the solicitation.
The participant category is broad by design. Congress and the SEC recognised that proxy contests and solicitations are frequently conducted not by a single individual but by coalitions, syndicates, and coordinated groups. Requiring only the lead filer to disclose while allowing the financial backers to remain anonymous would undermine the transparency objectives of the proxy disclosure rules. Participants must file Schedule 14A (or an amendment to it) disclosing their identity, background, and interests in the outcome of the solicitation.
For an activist investor who is conducting a solicitation to replace directors or influence a corporate vote, participant status requires disclosure of the activist's identity, any relevant prior criminal proceedings or court injunctions, their security holdings in the target company, and any arrangements or understandings with respect to the securities of the company. This information goes into the proxy statement that all solicited shareholders receive, giving those shareholders visibility into who is actually behind the campaign.
The question that CFI 155.02 addresses is how participant status applies when the activist operates through an investment vehicle, specifically an entity formed for the purpose of financing a specific proxy campaign.
What Did the SEC Establish in CFI 155.02 on July 9, 2026?
CFI 155.02, issued July 9, 2026, addresses the following specific scenario: an entity, such as a limited partnership, is formed for the purpose of raising funds to acquire securities of a specific registrant and engage in a proxy solicitation to change the composition of the registrant's board. Prospective investors in the entity are informed in advance of the specific purpose for which their funds will be used, including the identity of the targeted registrant and the proxy contest the entity intends to conduct. An investor then contributes capital to the entity.
The SEC's question in CFI 155.02 is whether that investor is a participant in the proxy solicitation. The answer is yes, with respect to each investor that contributed more than $500 to the entity.
The CFI's logic follows directly from the definition of participant. If a person finances a proxy solicitation, they are a participant. An investor who contributes capital to an entity that was formed, disclosed to be, and used for the purpose of conducting a proxy campaign at a specific target company is financing that proxy solicitation. The $500 threshold is the SEC's practical mechanism for distinguishing material financial contributors from de minimis investors who have nominal stakes in the vehicle but no meaningful financial relationship with the campaign.
The same underlying facts in CFI 155.02 were also addressed in CFI 110.09, which applies the same analysis to Schedule 13D. When an entity is formed to finance the acquisition of securities of a specific issuer and engage in an activism campaign, the investors who provide acquisition financing must be disclosed under Item 3 of Schedule 13D. The July 9 package thus imposes parallel disclosure obligations under both the proxy rules (CFI 155.02 via Schedule 14A) and the beneficial ownership rules (CFIs 110.09 and 110.10 via Schedule 13D) for the same category of formed entity.
What Is the $500 Threshold and Why Does It Matter?
The $500 threshold in CFI 155.02 is the materiality cutoff below which an investor's contribution to the activist vehicle is treated as de minimis and the investor is not required to be disclosed as a participant. An investor who contributes $500 or less is not a participant under CFI 155.02. An investor who contributes more than $500 is a participant and must be named in the proxy solicitation materials.
The $500 threshold is operationally significant for three reasons.
First, it is extremely low relative to the typical capital structure of an activist fund. Most activist funds raise minimum commitments in the millions of dollars. An LP that contributes $1 million to an activist fund formed to target a specific company is not near the $500 threshold; they are 2,000 times above it. The threshold means that virtually every meaningful LP in a purpose-built activist vehicle will be a required participant disclosure.
Second, the threshold applies at the investor level, not the campaign level. It is not asking whether the campaign as a whole is material; it is asking whether this particular investor contributed more than $500 to the specific entity. This prevents the use of nominee structures or split-contribution arrangements to keep individual investors below the disclosure threshold.
Third, the $500 threshold appears to correspond to an existing threshold in the Schedule 13D context, specifically the $500 mentioned in CFI 110.09 which uses identical language for the Schedule 13D Item 3 disclosure obligation. The parallel thresholds suggest the SEC's intent to create consistent treatment across the two disclosure regimes for the same activist vehicle structure.
The practical effect for activists: any purpose-built campaign vehicle must either accept that every meaningful investor will be a publicly disclosed participant in the proxy solicitation, or structure the campaign without using a purpose-built entity to raise financing. The latter option is still available, but it forecloses the use of capital-raising structures that involve informing investors of the specific target and campaign before they invest.
What Is the Specific Scenario the CFI Addresses: Entity Formed to Finance a Proxy Campaign
The fact pattern in CFI 155.02 is specific, and it is worth being precise about what it covers and what it does not, because the participant status analysis is narrow in its factual scope.
CFI 155.02 covers an entity that is formed for the purpose of raising funds to acquire securities of a specific registrant and engage in a proxy solicitation at that registrant. The critical elements are all three of these: formed for the purpose of raising funds, to acquire securities of a specific registrant, and to engage in a proxy solicitation at that registrant.
Each element carries significance.
"Formed for the purpose of raising funds" distinguishes a purpose-built campaign vehicle from an existing activist fund that happens to take a position in a company and later launches a campaign. An existing fund that raises capital from investors without disclosing a specific target, then later identifies a target and launches a campaign, is in a different factual position from a vehicle formed with the target and campaign already identified. The CFI's logic is that investors in the purpose-built vehicle are knowingly financing a specific proxy campaign; investors in a general-purpose fund are not necessarily financing any specific campaign.
"Specific registrant" confirms that the CFI applies to single-target vehicles. A vehicle raised to pursue a basket of activism opportunities at multiple as-yet-unnamed companies is in a different position from a vehicle raised to pursue a campaign at Company X specifically.
"Engage in a proxy solicitation" ties the participant status specifically to the proxy solicitation context. The same entity's Schedule 13D obligations are addressed in CFIs 110.09 and 110.10. CFI 155.02 addresses the proxy rules dimension separately.
For corporate defence teams, the practical implication is that the CFI is most directly relevant when the activist announces that they are forming a new vehicle to run a campaign. If the activist's campaign vehicle exists as a pre-existing fund, the participant disclosure obligations are different and CFI 155.02's bright-line rule does not automatically apply.
What Information Must the Entity Disclose About Each $500+ Investor?
Once an investor is identified as a participant under CFI 155.02, the proxy solicitation materials must include the information required by Schedule 14A for each participant. The required disclosures for a participant who is a natural person include:
Name and business address.
Any arrangement or understanding with any other person pursuant to which the participant is, or was, a participant in the solicitation.
Any substantial interest, direct or indirect, in any matter to be acted upon at the meeting, including security holdings in the registrant.
Any material interest in any contract or proposal to be acted upon at the meeting.
Any prior criminal proceedings or court injunctions within the past 10 years.
The participant disclosure must be included in the proxy statement or an amendment to it filed before the solicitation is made. For an activist proxy campaign, this means the activist's proxy statement must name and describe each of the investors who contributed more than $500 to the campaign vehicle, along with the required information about each of them.
The scale of this disclosure obligation should not be underestimated for large activist campaigns. A purpose-built vehicle that raises $500 million from 50 institutional investors would be required to disclose all 50 as participants, with name, address, interest, and background information for each. The resulting proxy statement participant disclosure section could be substantial.
For sophisticated institutional investors in activist vehicles, this participant disclosure obligation changes the calculus of investing in purpose-built campaign vehicles. Pension funds, sovereign wealth funds, endowments, and other institutional investors that participate in activist vehicles prefer to maintain a degree of anonymity about their specific investment decisions. A mandatory participant disclosure that names them as financial backers of a campaign against a public company exposes them to potential reputational consequences, commercial relationship risks with the target company, and scrutiny from the target company's other institutional shareholders who may themselves be investors in the activist's other funds.
What Does This Change for How Activists Structure Their Campaigns?
CFI 155.02, combined with CFIs 110.09 and 110.10, significantly increases the transparency cost of using purpose-built capital-raising structures for single-company activism campaigns.
Before the July 9 CFIs, the disclosure obligations for investors in activist vehicles were less certain, particularly for participants in the proxy context. While Schedule 14A's participant definition had long been broad, the specific application to LP investors in a formed entity was a grey area that activists could navigate with some degree of opacity.
After the July 9 CFIs, the path is clear. Activists who want to maintain investor anonymity in their campaign financing must avoid forming purpose-built entities that inform investors of a specific target before they invest. The alternative structures available include:
Using a pre-existing diversified fund that has not been presented to investors as a vehicle for a specific campaign. Investors in a general-purpose activist fund who invest without knowing the specific target are in a different position from investors in a purpose-built vehicle who are explicitly told the target and campaign intent before investing.
Financing the campaign from the activist's own balance sheet without raising external capital for the specific campaign. This limits the scale of the campaign to the activist's own resources but avoids the participant disclosure obligation for external investors.
Proceeding with the participant disclosure and accepting the transparency cost. Some activists may conclude that the required disclosure is manageable and that the ability to raise purpose-built campaign capital is worth the disclosure cost.
The Gibson Dunn analysis of the July 9 CFIs noted that these interpretations update four sections of the staff's CFI guidance and clarify several recurring issues in the shareholder activism context. The combined effect of the six CFIs is to make campaign financing structures more transparent at multiple levels: investor identity through the proxy participant rule (CFI 155.02), investor financing through Schedule 13D Item 3 (CFI 110.09), the investing entity's relationship to the campaign through Schedule 13D Instruction C (CFI 110.10), and the TRS position through beneficial ownership (CFIs 105.08 through 105.10).
What Does This Mean for Corporate Defense: Who Are the Real Principals Behind the Campaign?
From the corporate defence perspective, CFI 155.02 is the most directly useful of the July 9 CFIs for understanding the true principals behind an activist campaign.
Before the CFI, a proxy statement from an activist might disclose the lead activist fund as a participant and name its principals, while the investors who financed the campaign vehicle remained private limited partners whose identities were not publicly available. The target company and its shareholders knew who was running the campaign but not necessarily who was funding it.
After CFI 155.02, where the activist has used a purpose-built vehicle that informed investors of the specific target before they invested, every investor contributing more than $500 must be disclosed as a participant. This disclosure is available to the target company, all other shareholders of the target, the financial press, and the public at large.
The corporate defence implications:
The target company can identify the institutional investor base that is aligned with the activist. If a pension fund, endowment, or sovereign wealth fund that the target company regarded as a passive long-term holder is disclosed as a participant in the activist vehicle, that changes the target company's understanding of its shareholder base and the likely voting dynamics of the contest.
The target company can identify any commercial conflicts or relationships between the activist's investors and the target company. A financial institution that has a credit facility with the target company but is also disclosed as an investor in the activist vehicle creates a relationship management issue that the target company can address directly.
The target company can assess the concentration of campaign financing. If a single large investor accounts for the majority of the activist vehicle's capital, that investor's interests and views become particularly important to understand as the target company formulates its response to the campaign.
The target company's IR and legal team should review the participant disclosure in the activist's proxy statement as soon as it is filed, identify each participant, cross-reference them against the target company's shareholder base and commercial relationships, and assess the implications for the campaign's likely success and the target company's response strategy.
What Must Your IR and Legal Team Update in Their Activist Monitoring Playbook?
Three specific updates to the activist monitoring and response playbook after CFI 155.02.
Review proxy statements from activists for participant disclosures. When an activist files a proxy statement, the participant disclosure section now should name each investor who contributed more than $500 to any purpose-built vehicle used to finance the campaign. Make reviewing that participant list the first step in the proxy response analysis. Map each participant to the target company's institutional investor relations database, commercial relationship database, and any other relevant relationship registry.
Update the early warning monitoring framework. When an activist begins accumulating a position, one of the signals that the accumulation is campaign-related rather than passive investment is the formation of a new investment vehicle that is being marketed to investors. If your monitoring programme tracks activist fund formation activity, the formation of a purpose-built vehicle naming your company as a target may itself be a monitoring trigger that allows you to identify likely campaign investors before the proxy statement is filed. The CFI clarifies that those investors will eventually be disclosed, which is useful for anticipating who will be in the participant list.
Assess the interaction with investor relations strategy. If the participant list reveals that institutional investors who are also current shareholders of your company are financing the activist campaign, those investor relationships require immediate and specific engagement. The standard IR approach of broad shareholder engagement needs to be supplemented with direct conversations with the participants to understand their specific concerns and whether a resolution can be reached that avoids a contested proxy fight.
How Does CFI 155.02 Interact With the New 13D Disclosures in CFIs 105.08 through 105.10?
The July 9, 2026 package of six CFIs creates an interlocking transparency framework across both the beneficial ownership reporting rules and the proxy solicitation rules. Understanding how they interact is essential for a complete picture of what the package requires.
CFI 105.08 confirmed that a standard cash-settled TRS does not create beneficial ownership. CFI 105.09 confirmed that a TRS with voting or acquisition rights does. CFI 105.10 addressed the evasion scheme standard. These three CFIs primarily affect how an activist can build economic exposure before filing a Schedule 13D.
CFIs 110.09 and 110.10 addressed the Schedule 13D content obligations once the filing threshold is crossed. CFI 110.09 requires that the investors who financed the acquisition through a purpose-built vehicle be identified in Item 3 of Schedule 13D. CFI 110.10 addresses the Instruction C disclosure for persons controlling the filing entity.
CFI 155.02 then extends the same investor identification obligation to the proxy solicitation context. An investor who contributed more than $500 to a purpose-built campaign vehicle may need to be disclosed both in the Schedule 13D (under CFI 110.09) and in the proxy statement (under CFI 155.02) if the same vehicle is used for both the acquisition and the proxy solicitation.
The interaction produces a dual-track disclosure obligation for purpose-built vehicles. At the Schedule 13D filing stage, the entity's investors are disclosed under Item 3. When the proxy solicitation begins, the same investors are again disclosed as participants under Schedule 14A. The result is that investors in purpose-built campaign vehicles face public identification at two separate stages: acquisition disclosure and proxy solicitation disclosure.
Frequently Asked Questions
What is SEC CFI 155.02?
CFI 155.02, issued by the SEC's Division of Corporation Finance on July 9, 2026, addresses the proxy rules under Schedule 14A. It establishes that an investor who contributes more than $500 to an entity formed for the purpose of raising funds to acquire securities of a specific registrant and engage in a proxy solicitation at that registrant is a participant in the proxy solicitation. As a participant, the investor must be disclosed in the activist's proxy statement, along with the information required by Schedule 14A for participants.
Who is a "participant" in a proxy solicitation?
Under Instruction 3 of Item 4 of Schedule 14A and Rule 14a-2, a participant includes any person on whose behalf a proxy solicitation is made, any person who directly or indirectly solicits proxies on behalf of the filer, any committee or group formed to solicit proxies, and any person who finances or organises the solicitation. CFI 155.02 confirms that investors who finance a purpose-built proxy campaign vehicle are participants to the extent they contribute more than $500.
Does the $500 threshold apply to all activist funds?
No. CFI 155.02's analysis applies specifically to entities formed for the purpose of raising funds to acquire securities of a specific registrant and engage in a proxy solicitation at that registrant. A pre-existing diversified activist fund that has not been marketed to investors as a vehicle for a specific campaign is in a different factual position. The $500 threshold creates automatic participant status for investors in purpose-built single-target vehicles, not for investors in general-purpose activist funds.
What must be disclosed about each $500+ investor in an activist entity?
Schedule 14A requires participant disclosures to include name, business address, security holdings in the registrant, any material interests in matters to be acted upon, any arrangements or understandings with respect to the solicitation, and any relevant prior criminal proceedings or court injunctions within the past 10 years. These disclosures are included in the activist's proxy statement and are publicly available to all shareholders of the target company.
How does CFI 155.02 change activist campaign structures?
CFI 155.02 increases the transparency cost of using purpose-built capital-raising vehicles for single-company proxy campaigns. Activists who want to maintain investor anonymity must either use pre-existing diversified funds (avoiding the purpose-built vehicle structure), finance campaigns from their own balance sheet without external capital, or accept that every investor contributing more than $500 to a purpose-built vehicle will be publicly disclosed as a participant.
Key Takeaways
- CFI 155.02, issued July 9, 2026, establishes that any investor contributing more than $500 to an entity formed for the purpose of raising capital to acquire securities of a specific registrant and engage in a proxy solicitation at that registrant is a participant in the proxy solicitation and must be disclosed under Schedule 14A.
- The $500 threshold is extremely low relative to typical activist fund commitments. Virtually every meaningful LP in a purpose-built campaign vehicle will be a required participant disclosure.
- The participant disclosure must be included in the activist's proxy statement and is publicly available to the target company, all other shareholders, and the general public.
- CFI 155.02 applies specifically to purpose-built single-target vehicles. Pre-existing diversified activist funds that have not been presented to investors as vehicles for a specific campaign are in a different factual position.
- Combined with CFIs 110.09 and 110.10 (requiring investor identification in Schedule 13D), the July 9 CFI package creates a dual-track disclosure obligation for purpose-built campaign vehicles: investor identification at the Schedule 13D filing stage and again at the proxy solicitation stage.
- For corporate defence teams, the participant disclosure provides visibility into the institutional investor base that is financing the activist campaign, which changes the IR engagement strategy and the assessment of the contest's likely outcome.
- IR and legal teams should review proxy statement participant disclosure sections as the first step in proxy response analysis, map participants against the target company's shareholder and commercial relationship databases, and update early warning monitoring frameworks to track activist vehicle formation as a pre-filing signal.
- Activists who wish to maintain investor anonymity have three options post-CFI 155.02: use pre-existing diversified funds, self-finance campaigns, or accept public participant disclosure for every investor contributing more than $500 to a purpose-built vehicle.
