The CFO’s Role in an M&A Process: From Diligence to Close 

Mergers and acquisitions are among the most consequential events in the life of any company. Whether you are the acquirer or the target, whether the deal is a strategic acquisition, a private equity recapitalization, or a full exit, the financial complexity involved is extraordinary. And the CFO, or the person playing the CFO role in your organization, sits at the center of nearly every critical decision point in the process. 

Many founders discover this the hard way. They enter an M&A process underestimating the financial workload, assuming that their existing team and systems can handle the demands of diligence on top of normal operations. That assumption is almost always wrong. The result is delayed deals, renegotiated terms, and in some cases failed transactions that could have been avoided with better preparation. 

This post is for founders and executives who want to understand what a CFO actually does in an M&A process and why having experienced financial leadership in place long before a deal materializes is one of the best investments a growing company can make. 

The Pre-Deal Work That Most Companies Miss 

Every serious buyer will conduct financial due diligence. That process will involve a detailed review of your historical financial statements, your accounting policies, your revenue recognition practices, your working capital trends, your debt and equity structure, and a wide range of operational metrics. The depth and duration of this review will depend on the size and complexity of the deal, but even for relatively straightforward transactions, the scope is substantial. 

A CFO who understands what is coming begins preparing for diligence long before a letter of intent is signed. This means ensuring that historical financials are accurate, complete, and prepared on a consistent basis. It means documenting accounting policies in writing. It means cleaning up any classification errors or inconsistencies that an acquirer’s advisors would flag. It means being able to produce a quality of earnings analysis, either independently or in collaboration with the buyer’s advisors, that stands up to scrutiny. 

Companies that are not diligence-ready face two problems. The first is that gaps in their financial records slow down the process, which costs time and money and creates negotiating leverage for the buyer. The second is that material issues discovered mid-diligence can result in price adjustments or broken deals. According to Deloitte research, approximately 30% of M&A transactions result in price reductions during diligence, and financial issues are among the most common causes. 

Building and Defending the Financial Model 

In any M&A transaction, the financial model is the single most important document your company will produce. It drives valuation discussions, informs the deal structure, and shapes every assumption the buyer makes about the future performance of the business. Building that model and defending it under questioning from sophisticated financial buyers and their advisors is demanding work that requires both technical skill and strategic judgment. 

A CFO will build the forward model in a way that is both ambitious and defensible. This means grounding every projection in historical data, documenting the assumptions behind growth rates and margin targets, and anticipating the questions that experienced diligence teams will ask. It also means being prepared to walk an acquirer through the model in detail, explaining variances from prior budgets and demonstrating a clear understanding of the drivers behind the business. 

This is not work that can be delegated to a junior finance team member or assembled from last year’s budget in a weekend. It requires the expertise of someone who has been through M&A processes before and understands the language, expectations, and standards that institutional buyers bring to the table.

Working Capital and Deal Mechanics 

One area where many founders are caught off guard in M&A deals is the working capital adjustment. Most M&A transactions include a working capital target in the purchase agreement, meaning that the final purchase price is adjusted up or down based on the actual working capital delivered at close versus the target amount negotiated during the deal. 

If your accounts receivable are higher than expected at close, you may receive more. If your payables are understated or your inventory is overvalued, the adjustment goes the other way. These adjustments can meaningfully affect the net proceeds a seller receives, and they are frequently contested between buyer and seller advisors after close. 

A CFO who understands working capital mechanics will negotiate the target calculation methodology carefully, ensure that the company’s accounting practices are documented clearly, and track the working capital position closely in the weeks leading up to close. This is technical, detail-oriented work that pays off directly in the final proceeds. 

Managing the Business While the Deal Gets Done 

One of the most underappreciated aspects of a CFO’s role in an M&A process is ensuring that the business does not deteriorate while the transaction is underway. Deals take time. A typical M&A process from signed LOI to close takes three to six months, and during that period the company still needs to operate. Customers still need to be served. Employees need to stay engaged. Financial performance needs to hold. 

This is harder than it sounds. Key employees often become distracted or anxious when word of a deal circulates. Management bandwidth is consumed by diligence requests. Decision-making can slow down because leaders are uncertain about what commitments they should be making during a pending transaction. 

A strong CFO provides stability and continuity during this period. They keep the finance team focused on the operating business, manage the flow of information to the diligence team in a disciplined way, and ensure that leadership is not so consumed by the deal that the business metrics that made the company attractive in the first place start to erode before close.
