Registered Investment Adviser M&A: Client Consents and Advisers Act Compliance

The registered investment adviser (RIA) sector has been a consistent source of M&A activity, driven by succession planning at founder-led advisory firms, platform consolidation by acquirers building scale, and private equity investment in the wealth management space. Unlike most M&A transactions, RIA acquisitions are subject to a statutory constraint with no parallel in industrial M&A: the Investment Advisers Act of 1940 prohibits an investment adviser from assigning an advisory contract without the client's consent, and a change of control of the adviser constitutes an assignment of all existing advisory contracts by operation of law.

This sub-article is part of the Financial Services M&A: Legal Guide. It covers the RIA M&A market and the regulatory framework that governs these transactions; Section 205(a)(2) of the Advisers Act and the scope of the assignment prohibition; what constitutes a direct versus indirect assignment, including the 25% ownership change threshold for indirect assignment; negative consent mechanics and the procedural requirements for a valid negative consent notice; affirmative consent requirements and when affirmative consent is necessary; advisory contract review and custody documentation in diligence; ADV amendment obligations for Parts 1 and 2 post-closing; SEC notice requirements and wrap-fee program considerations; state notice filings across jurisdictions; books and records transfer obligations; Form 13F and 13H filing considerations for large advisers; custody rule implications and qualified custodian requirements; fiduciary duty considerations in the transition period; IAR transitions and Form U4 amendment obligations; continuing education and licensing requirements for transitioning personnel; and successor adviser liability for the target's pre-closing conduct.

RIA M&A Market Overview and Regulatory Framework

The registered investment adviser sector encompasses a wide range of business models, from sole-proprietor financial planners with a handful of retail clients to large institutional managers overseeing hundreds of billions in assets across multiple strategies and client types. The common thread is registration under the Investment Advisers Act of 1940: advisers managing $110 million or more in regulatory assets under management (AUM) are required to register with the SEC as investment advisers, while advisers below that threshold generally register with the applicable state securities regulator in the state where they maintain their principal office.

M&A activity in the RIA sector is driven by several structural factors. Founder succession is the most common motivation at smaller firms: principals who built their practice over decades often have no internal successor and find acquisition by a larger platform to be the most viable exit path. At the other end of the spectrum, large RIA aggregators backed by private equity capital pursue a roll-up strategy, acquiring dozens of independent advisory firms to build scale, shared infrastructure, and a national distribution footprint.

The regulatory framework applicable to RIA acquisitions is primarily the Investment Advisers Act of 1940 and the rules thereunder, administered by the SEC's Division of Investment Management. State securities laws add a concurrent layer of regulation for state-registered advisers and for the state registrations of investment adviser representatives employed by federally registered advisers. The Financial Industry Regulatory Authority (FINRA) is not the primary regulator for RIAs that are not also broker-dealers, but FINRA's CRD system is the registration database used to maintain IAR registrations in states that participate in the Investment Adviser Registration Depository (IARD) system.

The fundamental regulatory constraint in RIA M&A flows from the Advisers Act's prohibition on assignment of advisory contracts without client consent. Every other compliance obligation in an RIA acquisition, including ADV amendment, IAR re-registration, and custody rule compliance, is secondary to getting the consent process right. An acquisition that closes without valid client consent to the assignment of affected advisory contracts is not merely a technical violation: the advisory contracts for non-consenting clients are void from the date of assignment, meaning the successor adviser has no legal basis for collecting advisory fees from those clients and is potentially exposed to fee disgorgement and other remedies.

Section 205(a)(2): The Assignment Prohibition

Section 205(a)(2) of the Investment Advisers Act makes it unlawful for a registered investment adviser to enter into, extend, renew, or perform any investment advisory contract that "provides for assignment of such contract by the investment adviser without the consent of the other party to the contract." The statute thus prohibits not merely the act of assignment without consent, but also the entry into any contract that purports to permit such an assignment, closing off the possibility of drafting around the requirement through contractual provisions authorizing automatic assignment on a change of control.

The Advisers Act defines "assignment" to include not only any direct assignment of the advisory contract itself, but also any transfer of a material interest in the advisory firm. Specifically, the Act provides that assignment includes "any transfer of a material interest in [the] investment adviser." This broad definition captures indirect assignments that occur through changes in ownership or control of the adviser, even when the advisory contracts themselves are not formally transferred to a new legal entity.

The practical significance of the assignment prohibition is that it makes client consent a condition precedent to consummating virtually any RIA acquisition. A buyer who structures its acquisition as a purchase of the RIA's equity (a stock purchase) rather than its assets does not avoid the consent requirement, because the change of control of the adviser constitutes an indirect assignment that is equally prohibited under Section 205(a)(2). An asset purchase structure in which the buyer acquires the RIA's client contracts directly constitutes a direct assignment, which also requires consent. There is no transaction structure for an RIA acquisition that avoids the assignment prohibition.

The assignment prohibition applies to advisory contracts with all clients, including retail clients, institutional clients, and private fund clients. For private fund clients, the fund's investment advisory agreement with the RIA is the relevant contract, and an assignment of that agreement requires the consent of the fund (typically acting through its board of directors or general partner) rather than the individual limited partners or shareholders.

What Constitutes an Assignment: Direct vs. Indirect, and the 25% Ownership Change Threshold

The Advisers Act defines "assignment" to include "any transfer of a material interest in [the] investment adviser." SEC rules and staff guidance have interpreted "material interest" for purposes of the indirect assignment trigger, providing that a change in a controlling block of the adviser's outstanding voting securities constitutes an assignment. The SEC has historically interpreted a controlling block as any block of 25% or more of the adviser's outstanding voting securities, so that a transaction that transfers 25% or more of the adviser's voting equity to a new owner constitutes an indirect assignment of all advisory contracts.

The 25% threshold is not a bright line in all circumstances. The SEC staff has noted that a change in ownership below 25% can still constitute an assignment if the transferred block represents a controlling interest given the specific ownership structure of the adviser. For example, if an adviser is owned by two principals each holding 50%, and one principal transfers a 20% stake to a third party, that transfer would not by itself constitute a change of control (since the remaining principal still holds a majority). But if the transfer is accompanied by management rights, board representation, or veto authority that gives the new 20% holder effective control over the adviser's business, the SEC may view the transaction as a change of control constituting an indirect assignment.

A direct assignment of advisory contracts occurs in any transaction where the advisory contract itself is transferred from one legal entity to another. This typically arises in asset purchase structures where the RIA's client contracts are among the purchased assets. The buyer steps into the shoes of the seller as the counterparty to each transferred advisory contract, which is a textbook assignment requiring the consent of each client whose contract is being transferred.

A merger in which the RIA is the non-surviving entity also constitutes an assignment of all advisory contracts, because the RIA as the original contract counterparty ceases to exist as a legal entity and its contractual rights and obligations transfer by operation of law to the surviving entity. From the client's perspective, the counterparty to the advisory contract has changed, which is the economic equivalent of a direct assignment. The SEC and its staff have consistently confirmed that mergers involving the RIA as the non-surviving entity constitute assignments requiring client consent.

Negative Consent Mechanics: The 45-Day Notice Letter

The SEC staff has issued a series of no-action letters permitting the use of negative consent procedures in connection with RIA change of control transactions. Under a negative consent procedure, the adviser provides each client with a written notice describing the proposed transaction and the material facts about the new ownership, and the client is deemed to have consented to the assignment if the client does not object or terminate the advisory relationship within a specified notice period. The client's silence, rather than an affirmative act, constitutes consent.

The SEC staff's no-action guidance has articulated several requirements for a valid negative consent notice. The notice must describe the proposed transaction in sufficient detail that the client can make an informed decision about whether to consent to the new ownership. At a minimum, the notice should identify the acquirer, describe the nature of the transaction (merger, stock purchase, asset purchase), identify the key individuals who will be responsible for managing the client's account after closing, describe any material changes to the advisory services or fee arrangements, and clearly inform the client of the right to terminate the advisory relationship without penalty before the effective date of the assignment.

The notice period must be reasonable and must provide clients with adequate time to review the notice, seek advice, and decide whether to consent or terminate. The SEC staff has not specified a mandatory minimum notice period, but 45 days has emerged as the industry standard. Some practitioners use 60 days to provide additional margin, particularly for transactions where clients include retail investors who may be slower to respond or who have more complex circumstances to evaluate. The notice period should begin running before the closing of the transaction so that by the time the transaction closes, the consent period has either expired or is in its final days.

The negative consent notice is typically sent after signing of the acquisition agreement and before closing, during the period when all regulatory and other conditions to closing are being satisfied. The timing must be coordinated with the transaction schedule: if the negative consent period expires before closing, clients who did not object have technically consented to an assignment that has not yet occurred, which may require a follow-up notice if the closing is significantly delayed. Counsel should build the consent timeline into the acquisition agreement's condition structure, often including a condition that a specified minimum percentage of client AUM has consented (or not objected) before the buyer is required to close.

Affirmative Consent Requirements

Certain categories of advisory clients require affirmative consent to an assignment rather than mere non-objection to a negative consent notice. The most significant category is clients whose existing advisory contracts contain affirmative consent provisions: if the contract expressly requires the client's written approval before any assignment is effective, the negative consent procedure is not available for those clients, and the adviser must obtain a signed consent or a new advisory agreement before the assignment can occur.

Government entity clients present a particular affirmative consent consideration. Many public pension funds, endowments, and other governmental investors are subject to state or local laws that require affirmative board or committee approval before amending or extending significant contracts, including investment advisory agreements. For these clients, the signing of a new advisory agreement or a formal consent resolution by the governing body is the appropriate procedure, and the timeline for obtaining that approval must be factored into the overall transaction schedule. Government board meeting schedules can introduce delays of several weeks or months.

ERISA plan clients (including corporate pension plans, 401(k) plans, and other employee benefit plans) also merit careful attention. ERISA fiduciaries who are evaluating whether to consent to an advisory contract assignment must assess whether the proposed successor adviser satisfies their fiduciary duty of prudence under ERISA Section 404, including a review of the successor's qualifications, investment process, and fee structure. A change of control that results in materially different personnel managing the plan's assets may prompt ERISA plan clients to terminate and rebid their advisory mandates rather than consent to the assignment.

The mechanics of affirmative consent vary by client type. Retail clients may sign a new advisory agreement presented at or before closing. Institutional clients may require a more formal process involving their investment committees or boards. Fund clients may require a vote of the fund's independent directors or a consent of the general partner, depending on the fund's governance documents. In each case, the form of consent and the process by which it is obtained must be documented carefully, as the successor adviser will need to demonstrate valid consent if the assignment is later challenged by the client or by a regulator.

Advisory Contracts and Custody Documentation in Diligence

Due diligence on the target RIA's advisory contracts is the foundation of the consent process. Each advisory contract must be reviewed to determine its assignment provisions, any consent requirements, the term and termination provisions, the fee structure, and any conditions that might be triggered by a change of control. This review requires access to the executed contract file for each client, including any amendments, side letters, or other modifications that have been agreed since the original contract was executed.

Many RIA client contracts are based on standardized form agreements, but variations introduced over years of client negotiations can create meaningful differences among individual contracts. Some clients may have negotiated lower fee rates, performance-based fee arrangements, or non-standard termination provisions that affect the value of those client relationships and the mechanics of obtaining consent. Fee rate schedules attached to individual advisory contracts must be reviewed against the adviser's disclosed fee schedule on Form ADV Part 2A to confirm that all fee arrangements are appropriately disclosed.

Custody documentation review is a distinct component of RIA due diligence. The target adviser must maintain, under the custody rule (Rule 206(4)-2), documentation of the custodial arrangements for each client account, including the name and contact information of the qualified custodian holding each client's assets. The buyer must confirm that the target's custodial arrangements comply with the custody rule and that the transition of advisory responsibility will not disrupt the client's custodial relationship. Where the adviser serves as a trustee or has direct access to client funds, the custody rule imposes heightened requirements that must be confirmed as part of diligence.

Wrap fee program documentation requires specific attention. If the target adviser participates in wrap fee programs sponsored by broker-dealers, each program agreement must be reviewed to determine whether a change of control of the adviser requires notice to or approval from the wrap program sponsor, and whether the adviser's participation in the program can be assigned to the successor adviser without the program sponsor's consent. Some wrap program agreements require the sponsor's affirmative consent to any change in the management of the advisory team, even if they do not explicitly address assignment.

ADV Amendments: Part 1, Part 2, and Brochure Delivery

The Form ADV is the primary disclosure document for registered investment advisers, filed with and maintained by the SEC through the IARD system. Form ADV consists of two parts: Part 1 (the structured data form used by regulators and available to the public on the SEC's Investment Adviser Public Disclosure website) and Part 2 (the narrative brochure and brochure supplement provided to clients). Both parts must be amended to reflect the change of control and other material changes resulting from the acquisition.

Form ADV Part 1 must be amended promptly when the information reported on the form becomes materially inaccurate. A change of control is a material change to the information reported in Item 1 (basic information), Item 7 (financial industry affiliations), and Schedules A and B (direct and indirect owners and executive officers), at a minimum. The amendment must be filed through the IARD system and becomes publicly available on the IAPD website. Practically speaking, the Part 1 amendment should be filed on or promptly after the closing date.

Form ADV Part 2A (the firm brochure) must be updated to reflect material changes to the information disclosed to clients, including the change in ownership, any changes to the key personnel responsible for managing client accounts, any changes to the investment strategies employed, and any changes to the conflict of interest disclosures resulting from the new ownership structure. The updated Part 2A must be delivered to all existing clients either in full or through a summary of material changes document, with the full updated brochure available on request and through the IAPD website. The timing of Part 2A delivery is regulated: annual updates must be delivered within 120 days of the fiscal year end, but material interim changes should be delivered promptly to affected clients.

Form ADV Part 2B (brochure supplements for investment adviser representatives) must also be updated to reflect changes in supervision arrangements, disciplinary history, or other material information about the IARs who provide investment advice to retail clients. Post-closing, the successor adviser should review all existing Part 2B supplements and prepare updated supplements for any IARs whose circumstances have changed as a result of the transaction.

SEC Notice Requirements and Wrap-Fee Considerations

The SEC does not require advance notice of an RIA change of control transaction as a condition of the transaction's validity, unlike the Federal Reserve's advance approval requirement for bank holding company acquisitions. However, the SEC may conduct a cause examination of the successor adviser in the period following a significant change of control, particularly if the change involves a registered adviser with a large retail client base, outstanding compliance concerns, or prior enforcement history.

Advisers with $1 billion or more in AUM attributable to separately managed accounts are required to file Section 13F reports with the SEC on a quarterly basis, disclosing their holdings in equity securities meeting specified thresholds. An RIA acquisition that transfers management of a large equity portfolio to a successor adviser requires confirmation that the successor is filing 13F reports covering the acquired AUM in the quarter following the closing, and that the first post-closing 13F filing reflects the combined AUM under management. 13F filings are due within 45 days of the end of each calendar quarter.

Advisers and their principals who are large traders (defined as trading 2 million or more shares or $20 million or more in securities in a calendar day, or 20 million or more shares or $200 million or more in a calendar month) must register with the SEC on Form 13H. An RIA acquisition that causes the successor adviser to cross the large trader threshold, or that transfers large trader status from the target to the successor, requires prompt evaluation of Form 13H filing obligations for the post-closing entity.

Wrap-fee program participation requires specific post-closing notification. When the RIA is a participant in a wrap fee program sponsored by a third-party broker-dealer, the broker-dealer sponsor must typically be notified of the change of control and may have contractual rights to approve or reject the continuation of the advisory relationship under the program. The successor adviser should review all wrap program participation agreements and send required notices to each program sponsor promptly after the closing.

State Notice Filings Across Jurisdictions

SEC-registered investment advisers are exempt from state registration requirements under Section 203A of the Advisers Act, but they are subject to state notice filing requirements in states where they have a place of business or where they exceed a threshold number of clients (generally six or more clients in a state, though some states use different thresholds). A change of control of an SEC-registered adviser does not convert it to a state-registered adviser, but it does trigger the obligation to update the adviser's notice filings in all states where the adviser currently maintains those filings to reflect the new ownership information.

State notice filings for SEC-registered advisers are submitted through the IARD system as amendments to Form ADV Part 1. The filing fees associated with state notice filings vary by state and by the type of amendment being filed. The successor adviser's compliance team should maintain a current map of all states where the adviser has notice-filing obligations and confirm that each state's records are updated within the time periods those states require.

State-registered advisers face a more demanding post-closing filing process. A change of control of a state-registered investment adviser may require a new application for registration in the relevant state, a change of ownership notification within a specified number of days, or a formal approval from the state securities regulator before the transaction can close in that state. Each state's securities statute and regulations specify different requirements, and the compliance obligations of a state-registered RIA with clients in multiple states can be complex to map and satisfy on a coordinated basis.

Some states impose substantive review standards on changes of control of state-registered advisers that go beyond mere notification. These states may evaluate the qualifications of the new controlling persons, review the new ownership structure for potential conflicts of interest, or impose conditions on the approval of the change of control. The acquirer's counsel must identify these states early in the transaction planning process and factor the state review timeline into the overall closing schedule.

Books and Records Transfer Obligations

Rule 204-2 under the Investment Advisers Act requires registered investment advisers to make and maintain specified books and records for defined minimum retention periods. The records subject to the rule include trading records, client account records, correspondence, research materials, compliance policies and procedures, and financial records. Most record types must be retained for five years, with the most recent two years maintained in an easily accessible location (typically an electronic records system that can produce records within a short period for examination purposes).

In an RIA acquisition, the obligation to maintain the target's books and records for the remainder of the applicable retention periods passes to the successor adviser. If the transaction is structured as a merger in which the target is the non-surviving entity, all of the target's records become records of the surviving entity by operation of law. If the transaction is an asset purchase, the purchase agreement must address which records transfer to the buyer and which remain with the seller, and the buyer must ensure that the records it receives are sufficient to satisfy its ongoing regulatory obligations.

Electronic records require particular attention in post-closing integration. Advisory firms increasingly maintain their books and records in cloud-based systems, and the transition from the target's records platform to the acquirer's platform must preserve the integrity, accessibility, and searchability of the transferred records. Some records management systems impose contractual restrictions on data portability or charge significant fees for data export, which should be identified in diligence and addressed in the purchase agreement's representations and transition services arrangements.

Email and other communications records present a specific challenge in adviser acquisitions. Communications between the RIA and its clients, and communications among employees that relate to advisory services, are books and records subject to Rule 204-2. The successor adviser must ensure that it can access and produce these records for the applicable retention period, which may require maintaining access to the target's email archiving system or migrating archived email records to the acquirer's system. Gaps in communications records are a common examination finding following adviser acquisitions.

Form 13F, Form 13H, and Custody Rule Implications

Section 13(f) of the Securities Exchange Act requires any institutional investment manager that exercises investment discretion over accounts holding $100 million or more in Section 13(f) securities (equity securities traded on a national securities exchange, certain convertible notes, options, and warrants) to file quarterly reports on Form 13F disclosing those holdings. The filing obligation attaches to the institutional investment manager, defined as any person who exercises investment discretion with respect to accounts holding the requisite amount of Section 13(f) securities.

When an RIA acquisition transfers management of accounts holding Section 13(f) securities from the target to the successor, the successor assumes the 13F filing obligation for those accounts. The successor must confirm that its 13F filings for the first quarter after closing include all Section 13(f) securities managed as a result of the acquisition, with the filing due 45 days after the end of the relevant calendar quarter. Conversely, the target's 13F obligations terminate when it ceases to exercise investment discretion over the transferred accounts, which typically occurs at the closing date.

The custody rule (Rule 206(4)-2) requires investment advisers who have custody of client funds or securities to meet specific requirements designed to protect those assets. An adviser has custody when it holds, directly or indirectly, client funds or securities, or has authority to obtain possession of client funds or securities. In an RIA acquisition, the successor adviser must review each client relationship in which the target adviser had custody and confirm that the successor's arrangements satisfy all applicable custody rule requirements for each client.

For advisers to private funds, the custody rule provides an alternative compliance path: advisers to pooled investment vehicles that are audited annually by an independent public accountant registered with and subject to regular inspection by the PCAOB, and whose audited financial statements are distributed to fund investors within 120 days of fiscal year end, are exempt from certain custody rule requirements applicable to separately managed accounts. The successor adviser must confirm that the fund's audit arrangements will continue without interruption post-closing and that the audit firm relationship transfers appropriately in the transaction.

IAR Transitions, Successor Liability, and Fiduciary Duty Through Closing

Investment adviser representatives employed by the target RIA who provide investment advice to retail clients are required to be registered with the state securities regulator in each state where they have a place of business or where they have clients (subject to certain de minimis exemptions). IAR registrations are maintained through the FINRA CRD system and are associated with the sponsoring firm (the registered investment adviser that employs the IAR).

When an RIA acquisition results in IARs moving from the target firm to the successor firm, each IAR's Form U4 must be amended through the CRD system to reflect the change in sponsoring firm. The Form U4 amendment must be filed within 30 days of the employment change. For IARs who are moving from a firm registered only with state regulators to an SEC-registered firm, the state IAR registrations may need to be maintained by the successor if the successor is notice-filed in those states, or they may need to be terminated if the successor does not have an IAR registration obligation in those states.

Continuing education requirements for IARs must be tracked through the transition. IARs who hold certain state securities licenses may have annual or biennial continuing education obligations, and the records of those obligations are maintained in the CRD system by the sponsoring firm. The successor adviser must ensure that it maintains appropriate records of IARs' continuing education compliance and that no lapses occur as a result of the transition from the target firm to the successor.

Successor liability for the target adviser's pre-closing conduct is a function of transaction structure and applicable law. In a merger transaction, the surviving entity succeeds to all of the non-surviving entity's liabilities by operation of Delaware law (or the law of the applicable jurisdiction), including liability for pre-closing securities violations, pending client disputes, and any regulatory enforcement actions that were initiated or threatened before closing. Asset purchase structures do not automatically transfer the seller's liabilities to the buyer, but successor liability doctrines under state law, including the de facto merger doctrine and the product line exception, may impose liability on the buyer if the transaction effectively transfers the seller's entire business including its workforce and client relationships. SEC enforcement actions against the successor adviser for pre-closing conduct are not barred by an asset purchase structure, and the SEC has brought actions against successor advisers for violations committed by the predecessor where the successor controls the relevant assets and personnel.
