In September 2025, a $2.1 billion RIA in Denver was acquired for $38 million — roughly 9x EBITDA, in line with market multiples. Eighteen months later, the acquiring firm disclosed in an earnings call that $600 million in client assets had left. Not because of poor performance. Not because of fee disputes. Because three senior advisors, who collectively managed those relationships, resigned within six months of the deal closing.

The acquirer bought $2.1 billion in AUM. It kept $1.5 billion. The $38 million purchase price, justified by a multiple on the full book, was effectively a multiple on a smaller number. Nobody renegotiated.

This is the talent drain reshaping RIA M&A, and most acquirers are still underwriting deals as if advisors are furniture.

The retention data nobody puts in the pitch deck

RIA M&A volume has been staggering. Echelon Partners tracked over 350 RIA transactions in 2025, with total transacted AUM exceeding $800 billion. The buyer universe has expanded from traditional consolidators — Focus Financial Partners, Hightower Advisors, CI Financial — to include private equity firms, insurance companies, and even accounting firms building wealth management arms.

But the retention statistics tell a harder story. Industry research by DeVoe & Company found that acquirers retain approximately 85% of client assets in the first year post-acquisition — meaning 15% walks. For deals where key advisors depart, that figure drops to 60-65%. The difference between a successful deal and a failed one is not the multiple paid. It is whether the advisors stay.

The economics are stark. Consider a $1 billion RIA acquired at 10x EBITDA of $3 million — a $30 million purchase price. If 15% of assets leave in year one, and the firm’s 30% EBITDA margin holds, the acquirer paid 10x for earnings that are now $2.55 million. The effective multiple is 11.8x. If a key advisor leaves and 35% of assets follow, the effective multiple jumps to 15.4x — a price no buyer would knowingly pay.

Yet most deal models assume 90%+ retention. The models are wrong, and the acquirers know it.

Why advisors leave

The reasons are rarely about money. Acquirers typically offer competitive compensation — often better than what advisors earned independently. The departures are about autonomy, culture, and identity.

An advisor who spent 20 years building an independent practice has a specific way of serving clients: investment philosophy, communication style, even the art on the office walls. An acquirer that standardizes portfolios, mandates CRM workflows, and replaces the advisor’s name on the door with a corporate brand is asking that advisor to become an employee. Some accept the trade. Many do not.

The data bears this out. A 2025 survey by Cerulli Associates found that “loss of independence” ranked as the top concern among advisors considering a sale — above purchase price. Advisors who stayed post-acquisition cited “cultural fit” and “client service continuity” as more important than economics. The acquirers that retain advisors are not the highest bidders. They are the ones that leave the practice most intact.

This creates a paradox at the heart of RIA consolidation. The acquirer’s thesis is scale: centralized operations, unified technology, streamlined compliance. But the asset being acquired — the advisor-client relationship — is inherently personal and local. Every step toward standardization increases efficiency and increases departure risk simultaneously.

The acquirers who get it right

The most successful consolidators have learned to underwrite retention, not just AUM. Hightower Advisors, which has completed over 130 acquisitions, structures deals with significant equity participation for selling advisors — making them owners, not employees. The retention data shows it works: Hightower’s disclosed advisor retention exceeds 95%.

Focus Financial Partners takes a different approach, operating as a partnership where acquired firms maintain substantial autonomy. The trade-off is less operational synergy, but the model has proven resilient — Focus firms have shown stronger organic growth post-acquisition than peers at more integrated platforms.

Private equity buyers, newer to the space, are learning the same lesson expensively. Several high-profile PE-backed roll-ups have seen advisor departures spike in years two and three, when initial retention bonuses vest and the cultural integration accelerates. The pattern is consistent enough that sophisticated sellers now negotiate “culture clauses” — contractual commitments about operational independence — alongside price.

The counterargument: maybe AUM is what matters

The consolidation bulls argue that advisor departures, while painful, don’t invalidate the model. Client assets are sticky — even when an advisor leaves, a meaningful percentage of clients stay with the firm, especially if the transition is managed well. The acquirer’s brand, technology, and service model retain value independent of any individual.

There is truth here. DeVoe’s data shows that even in deals with advisor departures, acquirers retain 60-65% of assets — not zero. And the industry’s overall growth means that organic inflows often offset departure-related outflows within 18-24 months.

But this argument concedes the central point. If the bull case requires 18 months to recover from advisor departures, then the acquisition multiple should reflect that reality. Paying full price for assets that will partially leave, then waiting two years to rebuild, is not a 10x EBITDA deal. It is a 10x deal on hope.

The honest underwriting starts with a different question. Not “what multiple should we pay for this AUM?” but “what is the probability the advisors stay, and what is this firm worth if they don’t?” Most acquirers don’t ask the second question. The ones that do are winning.

The Denver deal’s $600 million in departed assets didn’t leave because the acquirer was incompetent. It left because three people decided they’d rather work somewhere else. In RIA M&A, the most important due diligence isn’t on the financials. It’s on the humans.
