The Role of the C-Level in M&A Transactions

The C-level role in M&A

Buying a business is one of the most consequential decisions an executive or business owner can make. Whether you're acquiring your first company or expanding an existing platform, the outcome of any deal hinges on what happens at the top: the vision, judgment, and decision-making authority that only you can provide.

More than 50% of acquisitions fail to meet expectations, according to Deloitte research. In most cases, the breakdown isn't in the financials or the legal documents. It's in the quality of leadership driving the transaction. Understanding what the C-level role actually requires, and where your gaps are, is the most important preparation you can do before pursuing an acquisition.

This article is written for business owners and executives considering buying a business in the lower middle market, typically companies valued between $2 million and $50 million. It draws on frameworks used by experienced acquirers and applies them to buyers who may be making their first acquisition or have limited deal-specific experience.

The five stakeholder groups in a deal

Deloitte's research on M&A best practices identifies five distinct stakeholder groups that must work together for a transaction to succeed. For large enterprises, each group may be staffed by dedicated teams. For a lower-middle-market buyer, you may personally fill two or three of these roles while sourcing external support for the others.

Understanding this structure helps you identify where you're exposed before a deal is underway, not after.

In a large company, an Investment Committee (IC) includes the CEO and senior executives who serve as the ultimate decision-makers, retaining accountability for every transaction. For a first-time buyer, you are the IC, even if it's just you and a trusted advisor in the room.

The IC should be involved early to establish a clear acquisition strategy and unified vision, then step back while other groups handle execution. The key responsibility isn't to manage every detail. It's to maintain strategic clarity and avoid letting momentum replace judgment.

What you're accountable for as the buyer

Regardless of the size of your team or the depth of your deal experience, four areas of accountability belong to you as the C-level buyer. These cannot be fully delegated, even to the best advisors.

Strategic direction

You must be able to articulate why you're making this acquisition and how it advances your goals. This means defining your acquisition criteria before you start looking: industry, size, geography, customer concentration, owner-dependency, and growth profile. Without this clarity, you'll waste months evaluating deals that were never right for you.

Financial oversight

You don't need to build the financial model yourself, but you do need to understand what it says and challenge the assumptions behind it. This includes understanding how the business is valued, what the deal structure means for your returns, and how the financing affects your cash position post-close. A CFO or financial advisor can support this work, but the final judgment on capital deployment is yours.

Governance and decision-making

One of the most underestimated risks in any acquisition is "deal fever," the momentum that builds as a deal progresses and makes it emotionally harder to walk away even when the facts say you should. Your role as the C-level is to pressure-test the deal at every stage: Is this still the right target? Are the projections realistic? What's the downside if the business underperforms?

Stakeholder communication

You will be the face of this transaction to the seller. Sellers in the lower middle market often have deep emotional ties to their businesses, and they are evaluating you as much as you're evaluating them. Your credibility, communication style, and demonstrated seriousness directly affect whether the deal proceeds on favorable terms.

CEO, CFO, and COO responsibilities

In an established acquirer, M&A responsibilities are divided across the executive team. For a buyer who wears multiple hats, understanding how these roles are divided helps you identify where to focus your energy and where to lean on external support.

If you're a solo buyer or part of a small team, you are likely functioning as CEO and CFO simultaneously. This is manageable with the right advisors, but it requires honest self-assessment. Where is your financial literacy strongest? Where do you need a CPA or financial advisor to fill in? Answering these questions before a deal starts prevents expensive gaps from surfacing mid-transaction.

What experience do you actually need?

The honest answer is that there is no minimum credential required to buy a business. But the gap between "business owner" and "experienced acquirer" is real, and it has measurable consequences for deal outcomes.

For context, corporate development professionals at the Managing Director level, the career equivalent of running an M&A program, typically have a decade or more of deal experience. At that level, a team might review 50 to 100 deals per year and close only 2 to 4. Closing zero deals in a given year is, according to practitioners, entirely plausible.

For a first-time buyer, this context is useful not to discourage you, but to calibrate expectations. Buying a business takes longer, involves more complexity, and requires more professional support than most buyers anticipate going in.

When advisors can fill your gaps and when they can't

External advisors play a critical role in any acquisition, but their value depends on how clearly you understand what they can and cannot replace. Deloitte's research is direct on this point: advisors "augment" internal capabilities. They do not replace the strategic judgment and decision authority of the buyer.

The key decision for any buyer is weighing the cost of experienced advisors against the risk of running a flawed process. For a first-time buyer, that calculation almost always favors investing in advisors. The cost of a missed due diligence red flag or a poorly structured deal is far higher than advisor fees.

Some buyers need advisor support on every deal. Others develop internal capability over time and use advisors selectively. Where you fall depends on your experience, your team, and the complexity of the specific transaction.

Common C-level mistakes in M&A transactions

The 50%+ deal failure rate cited by Deloitte isn't random. It clusters around specific, recurring mistakes, most of which originate at the leadership level. Recognizing these patterns before you're inside a deal is one of the most valuable things you can do to protect your investment.

One of the most underestimated mistakes is the time commitment required during live deal execution. Active deals do not pause for weekends. Data room questions, management meetings, lender conversations, and last-minute diligence requests all require immediate attention. Corporate development professionals routinely work 60 to 70 or more hours per week during deal sprints. For a buyer who also runs an operating business, this demand is significant and needs to be planned for in advance.

Integration planning is the other area consistently underestimated by first-time buyers. The decisions made during diligence, about management retention, operational changes, customer communication, and systems integration, directly determine whether the business performs as projected post-close. Waiting until after closing to think through these issues is one of the most reliable paths to underperformance.

Building your team around your gaps

The most effective lower-middle-market buyers don't try to do everything themselves. They define their role clearly, identify their gaps honestly, and build a team that compensates for those gaps before they become problems in a live deal.

The sequencing of when you engage each advisor matters as much as who you engage. Buyers who bring in legal counsel after informally agreeing to deal terms are at a disadvantage. Buyers who haven't spoken with a lender before making an offer have no real sense of their financing capacity or timeline. The best advisors add value throughout the process, not just at the finish line.
