Mergers and acquisitions are often discussed in terms of numbers. People talk about valuations, EBITDA multiples, growth assumptions, synergies, and returns on investment.
Those metrics absolutely matter, and as a CFO, I spend a great deal of time focused on them.
But after working through more than forty acquisitions over the last seven years, I can say with confidence that successful M&A is about far more than financial engineering.
At EP Wealth Advisors, acquisitions have been a major part of our growth story. We have grown to nearly $29 billion in assets under management, more than 500 employees, and close to fifty offices across the country.
We are now one of the top twelve registered investment advisers in the United States, operating in an industry that remains highly fragmented, with more than fifteen thousand RIAs nationwide.
Our growth has accelerated significantly over the past several years. We have been growing at a compound annual growth rate of nearly forty percent, effectively doubling the size of the firm every two years.
That growth has been driven largely through acquisitions, although we prefer to call them partnerships because, frankly, nobody likes to feel acquired.

The story of EP Wealth Advisors itself reflects the kind of long-term thinking that matters in business. The firm was founded by two childhood friends from San Diego who both ended up in wealth management.
Their first client was one of the cofounder’s grandmothers, who entrusted them with $800 to manage. That was the largest amount she felt comfortable investing at the time.
Today, the firm has grown into a multibillion-dollar business serving clients across the country.
In our industry, we operate under the fee-only registered investment adviser model. Unlike broker-dealers that generate commissions from transactions, our fees are based on the portfolios we manage for our clients.
Most of our clients are individuals with investable assets ranging from one to ten million dollars, and we provide a broad suite of services including financial planning, estate planning, retirement planning, and portfolio management.
Because our industry is so fragmented, M&A activity has become a significant driver of growth.
But growth alone is not enough. Acquisitions only create value when they are executed thoughtfully, integrated effectively, and supported consistently after the deal closes.
Over time, I’ve come to think about the CFO’s role in M&A as a lifecycle that extends well beyond the initial transaction.
It starts with valuation and underwriting, moves through due diligence and integration planning, and ultimately depends on what happens after the close. In many ways, the post-close phase is where the real work begins.
Understanding the CFO’s role in M&A
People often assume the CFO’s role in acquisitions is primarily financial oversight. That is certainly part of it. Valuation, capital planning, deal structure, forecasting, and risk management are all core responsibilities.
But one thing I’ve learned repeatedly is that creativity and flexibility are just as important as technical financial expertise.
Every acquisition is different, even when two deals appear nearly identical on the surface. The structure that works for one seller may not work for another. The timing of payments, the balance between cash and equity consideration, and the long-term expectations of both parties can vary dramatically.
In many cases, the CFO becomes a translator between strategy and execution. You are helping determine not only whether a deal makes financial sense, but also whether the business can realistically absorb and integrate the acquired firm.
That means balancing growth ambitions with operational realities.
When I think about the lifecycle of an acquisition, I break it into four broad stages. The first is valuation and underwriting. The second is due diligence. The third is integration planning. The fourth is post-close optimization.
Each stage presents its own challenges, and weaknesses at any point in the process can create problems later.

Valuation is more than choosing a multiple
One of the first questions in any acquisition is determining how to value the business.
The answer depends heavily on the industry and the structure of the transaction. In wealth management, we primarily use multiples of revenue or EBITDA. Those are the most common valuation metrics in our space.
I always joke a little when I see EBITDA figures because there is often a difference between the EBITDA that has been polished to look attractive and the actual free cash flow realities of the business.
Part of the CFO’s job is separating optimism from reality.
In our case, all of our acquisitions are asset purchases, which simplifies certain aspects of the process compared to equity transactions. But regardless of structure, valuation is only the starting point.
The more important question is what the business is likely to become over time.
That is where underwriting and forecasting come into play. A discounted cash flow model, for example, forces you to think beyond current performance and evaluate how the business may perform in the future.
What are the growth assumptions? Are they realistic? What external factors could impact performance? In our industry, market conditions play a major role in outcomes. Interest rates matter. Equity markets matter. Client asset flows matter.
You also need to think carefully about synergies.
When people hear the word “synergy,” they often immediately think about cost-cutting or headcount reductions. Those can certainly be part of the equation, but I think that definition is too narrow.
Some of the most valuable synergies we’ve realized have come from the people and expertise we acquired. Firms bring institutional knowledge, industry perspective, and intellectual capital that can strengthen the broader organization.
If you focus only on eliminating costs, you risk missing the real value of the acquisition.

Capital planning requires flexibility
Once valuation and underwriting are complete, the conversation shifts toward capital planning and deal structure.
This is where flexibility becomes essential.
When we negotiate transactions, one of the key questions is the mix of consideration. How much cash are we offering? How much equity? Are there holdbacks? Earn-outs? Deferred payments?
The answers have major implications for liquidity planning and cash flow forecasting.
Some deals may involve payouts over one or two years. Others may stretch much longer. Even transactions that appear structurally similar can require entirely different approaches depending on the priorities of the seller.
I cannot overstate how important adaptability is during this stage.
Rigid deal structures often fail because they ignore the human side of the negotiation. Sellers may care deeply about the future of their employees, the continuity of client relationships, or their own long-term involvement in the business.
A successful transaction requires understanding those motivations and structuring the deal accordingly.

Due diligence goes far beyond the financials
Once you move past the letter of intent, the due diligence process begins.
Financial due diligence is obviously critical. You are reviewing historical financial statements, evaluating key performance indicators, analyzing profitability, and validating revenue streams.
At EP Wealth Advisors, we perform what we describe as a “quality of earnings light” review. We spend time tracing cash flows to ensure the revenue we believe we are acquiring is actually there.
You also need to evaluate liabilities carefully.
Even in an asset transaction where liabilities are technically excluded, there may still be obligations that become part of the operational reality after the close. Office leases, vendor agreements, technology contracts, and long-term commitments can all influence the economics of the deal.
But financial diligence is only one piece of the puzzle.
Operational diligence and cultural diligence often end up consuming even more time.
Technology integration, for example, can become incredibly complicated.
At EP Wealth Advisors, we operate under a fully integrated model. Some firms in our industry function more like aggregators, acquiring businesses while allowing them to continue operating independently.
That is not our approach.
When we acquire firms, they become part of one integrated organization with a unified technology stack and operating model.
That means we have to think carefully about the timing and complexity of technology transitions.
Most importantly, every decision has to remain client-centric.
Clients did not ask for their advisory firm to be acquired. They simply expect the same level of service they have always received. If the acquisition creates disruption or confusion for clients, the integration has already started to fail.
That is why maintaining a seamless client experience becomes one of the most important operational priorities.

Culture determines whether acquisitions succeed
In my experience, culture and people are often the biggest determinants of success in M&A.
The acquisitions that have performed best for us are consistently the ones where the people joining the organization remained engaged and committed after the close.
You can see the difference in the numbers almost immediately.
When engagement is high, integration tends to move smoothly, collaboration increases, and growth opportunities emerge naturally.
When engagement is low, problems surface quickly.
One reason this matters so much is that many firms we acquire are entrepreneurial businesses built over decades. Some are only three- or four-person organizations. Others may have fifty or sixty employees.
For founders and senior leaders, selling the company is not just a financial transaction. It is emotional.
Many of these individuals have spent twenty or thirty years building their firms. Their identities are deeply connected to the business.
That is why empathy matters.
Acquisitions may happen frequently for large organizations, but for many sellers, this may be the only acquisition they experience in their entire career.
Clear communication becomes essential.
People need clarity around reporting structures, roles, responsibilities, and expectations. A CFO from a three-person firm is obviously not going to become the CFO of a five-hundred-person organization, so what is the right role for that person going forward?
Those conversations need to happen early.
Training is also critical, especially when technology platforms are changing. Teams need repeated and consistent support to ensure they are comfortable with new systems before they are expected to operate independently.
I’m also a strong believer in creating a single point of contact during integration.
Large organizations can feel overwhelming. People may not know who to contact for technology issues, operational questions, or process guidance.
Having one dedicated resource who can help navigate the organization reduces frustration and improves the overall experience.
Why integration planning matters so much
One of the biggest mistakes companies make is treating due diligence as the finish line.
In reality, due diligence is only valuable if you have a clear integration strategy for acting on what you learned.
At EP Wealth Advisors, we have a dedicated partnership integration team responsible for managing the process from due diligence through onboarding.
That team develops timelines, identifies objectives, coordinates departments, and ensures accountability across the organization.
The integration plan needs to answer practical questions.
How long will integration take? Can it realistically happen in a month, or will it require six months? What are the priorities? Who owns each responsibility?
In wealth management, integration can be particularly complex because client consent is required for account transitions. That process alone can take considerable time.
Another challenge is internal alignment.
Departments involved in integration still have their normal day-to-day responsibilities. Operations teams, client service teams, and portfolio management teams all have existing workloads.
If integration work is viewed as secondary or optional, progress slows dramatically.
That is why organizational buy-in is so important.
Everyone involved has to understand the strategic significance of the acquisition and their role in making it successful.

The real work begins after the close
One of my least favorite phrases is “post-merger optimization” because it sounds overly corporate and abstract.
But the concept itself is critically important.
Once the deal closes, the organization has to prove the acquisition thesis was correct.
That starts with measurement.
Can you track the acquired firm’s performance effectively? Do you have access to the right data? Are the assumptions from the original forecast actually materializing?
You also need to evaluate whether planned synergies are occurring on schedule.
If the acquisition was expected to generate cost savings or operational efficiencies, when are those benefits supposed to appear?
Our board often asks a simple but important question after an acquisition closes: “So what?”
In other words, what happens next?
That question forces accountability.
We go back to the original growth assumptions, discuss the forecast, and evaluate whether execution is aligning with expectations.
One of the most valuable things we do during this phase is maintain constant communication with newly acquired firms.
We gather feedback continuously.
Sometimes the feedback leads to new ideas and operational improvements. Sometimes it reveals frustrations or complaints. Both are valuable.
If you plan to pursue acquisitions consistently, your integration process needs to evolve continuously as well.
Support also matters enormously during this phase.
One mistake I see frequently in the industry is the assumption that once the acquisition closes, the acquired team should immediately perform at full capacity inside the new organization.
That expectation is unrealistic.
People need support, guidance, and time to adapt.
Successful integration is not something that happens automatically on day one.

What happens when things go wrong
No matter how thorough your due diligence process is, not every acquisition will unfold exactly as planned.
Growth assumptions may prove too optimistic. Market conditions may change. Integration challenges may emerge unexpectedly.
When that happens, the first thing I do is go back to the original assumptions.
Were the forecasts unrealistic? Did we miss something during diligence? Was the process itself flawed?
Sometimes the issue is simply that expectations were disconnected from reality.
For example, some acquisitions in our industry are succession deals involving founders who plan to retire within the next twelve to twenty-four months.
In those situations, we intentionally maintain lower growth expectations because the business may naturally stabilize rather than expand aggressively.
If a transaction was modeled with aggressive growth assumptions that never materialize, the problem may begin with the forecast itself.
But regardless of the cause, the solution usually starts with people.
We have open conversations about what is working and what is not.
At EP Wealth Advisors, we have a learning and development department dedicated to helping advisers build the skills necessary for success.
You cannot always control outcomes, but you can ensure the organization is properly resourced to respond to challenges.
The key is addressing problems directly rather than hoping they resolve themselves.

Communication can make or break an acquisition
One of the most important lessons I’ve learned through acquisitions is that communication failures create many of the worst integration outcomes.
Employees need transparency.
When people are left in the dark and suddenly informed that their company has been acquired, uncertainty spreads quickly.
That uncertainty often leads to disengagement, distrust, and turnover.
By contrast, the best integrations are usually the ones where employees are brought into the process thoughtfully and early.
That includes honest conversations about organizational changes, future roles, and potential synergies.
Headcount reductions, when necessary, should never come as a surprise.
In many cases, sellers already understand that synergies are part of the transaction and that those efficiencies may influence the purchase price.
But communication around those changes has to be handled carefully and respectfully.
If an integration reaches the point where management is rushing for the exits and employees feel abandoned, something has likely gone very wrong in the process.

Building infrastructure for repeatable M&A success
As acquisition activity scales, process discipline becomes increasingly important.
One common frustration in due diligence is inefficiency.
Sellers often end up answering the same questions repeatedly for different teams inside the acquiring organization.
That creates frustration and wastes time.
At EP Wealth Advisors, we addressed this by creating a dedicated partnership integration team that guides firms from the letter of intent through closing.
The team centralizes communication and coordinates information requests so the process remains organized and focused.
We also use project management tools like Monday.com to track responsibilities across departments and ensure accountability throughout the integration process.
The goal is not to create unnecessary administrative work.
In fact, one of the worst things an acquirer can do is ask for information that is not actually needed.
I’ve seen diligence request lists that are miles long when only a small fraction of the information is truly relevant.
Effective infrastructure should simplify the process, not complicate it.
M&A success is ultimately about balance
At its core, M&A is about balancing financial discipline with human understanding.
You need rigorous valuation models, thoughtful capital planning, thorough due diligence, and strong operational execution.
But you also need empathy, communication, flexibility, and patience.
The most successful acquisitions are not necessarily the ones with the most aggressive forecasts or the biggest synergies on paper.
They are the ones where strategy, people, operations, and execution align over time.
For CFOs, that means bringing more than financial oversight to the table.
It means acting as a strategic partner throughout the entire lifecycle of the transaction.
It means understanding that value creation does not stop when the deal closes.
In many ways, that is when the real work finally begins.
