Nowadays, mergers and acquisitions are no longer rare, high‑stakes events reserved for only the largest companies. With trillions of dollars in private equity capital seeking deployment and a surge of buy‑and‑build strategies targeting smaller firms, even mid‑market CEOs are finding acquisition conversations landing unexpectedly on their desks. Whether a company is preparing to buy or is being approached to sell, the CFO is increasingly thrust into the center of the process, often before the organization is truly ready.

What becomes clear, again and again, is that most companies dramatically underestimate what it takes to protect value in an M&A transaction. The financials, the operations, the people, and even the story behind the numbers all play a role. And when these elements aren’t aligned, deals fall apart, or close at a fraction of their potential value.

The difference between a successful exit and a failed one often comes down to the preparedness of the Office of the CFO. Moving beyond basic EBITDA analysis into deep operational scrutiny is essential to secure millions in value during the final stages of an acquisition.

Why So Many Deals Fail Before They Begin

Despite the excitement surrounding acquisitions, the statistics are sobering. A majority of businesses are not prepared to sell, and even among those that go to market, only a small fraction actually close. On the buy side, most acquirers report failing to achieve the value they expected. Both sides lose, and the root causes are surprisingly consistent.

One of the most common issues is the financial story. Many sellers provide tax returns or internal books that haven’t been optimized for valuation. Companies still operating on a cash basis during growth periods often present artificially depressed EBITDA, leaving millions of dollars on the table. A shift to accrual accounting alone can dramatically increase enterprise value, especially when buyers apply multiples of eight, ten, or more.

But the challenge goes deeper. Buyers look back three years, not three months. If the financial narrative across that period is inconsistent, incomplete, or poorly supported, trust erodes quickly. And trust is one of the most powerful drivers of valuation. When financials reconcile cleanly, when trends make sense, and when the story holds up under scrutiny, buyers move toward the higher end of their valuation range. When they don’t, deals stall or die.

The First Crime Scene: Due Diligence

The earliest and most common point of failure is due diligence. This is where the financial story is tested, and it’s where most deals collapse. Companies that haven’t maintained GAAP‑compliant records, haven’t reconciled accounts, or haven’t normalized EBITDA through proper add‑backs face immediate credibility issues.

Add‑backs, such as personal expenses, one‑time costs, or temporary consulting engagements, are essential for presenting a true picture of earnings. When done correctly and transparently, they are accepted by sophisticated buyers. When done sloppily or aggressively, they raise red flags.

Buyers also make mistakes. Many rush into a letter of intent based on marketing materials rather than rebuilding the financials themselves. Once trust begins to erode, renegotiations become contentious, and the deal becomes fragile. Experienced buyers take their time before issuing an LOI, ensuring the foundation is solid before moving forward.

The Working Capital Trap

Working capital is one of the most misunderstood (and most contentious) elements of a transaction. Sellers often assume they can walk away with their accounts receivable, while buyers expect a certain level of working capital to be delivered with the business. When expectations aren’t aligned early, deals fall apart late.

The typical “three‑month average” clause found in many agreements is vague and often unfair. Working capital should be neutral, not a windfall for the buyer or a haircut for the seller. Yet even among accountants, determining the right number can be surprisingly difficult. Without clarity, frustration builds, and negotiations break down.

Cashflow: The Canary in the Coal Mine

One of the most overlooked indicators of business health, and a major differentiator in M&A, is cash flow visibility. Many companies, even those with tens of millions in revenue, operate without a proper cash flow statement or forecast. This blind spot hides operational issues that could have been detected months or years earlier.

Cashflow forecasting is not just about timing inflows and outflows. It reveals deeper operational problems: inventory mismanagement, AR deterioration, margin compression, or uncontrolled spending. When companies can demonstrate a clear, consistent cash flow history and forward‑looking model, they stand out immediately in diligence. It signals discipline, transparency, and operational maturity.

What Buyers Value Most (and What CEOs Often Miss)

Beyond the financials, several operational and strategic factors significantly influence valuation:

• Leadership depth: Companies overly dependent on the founder or CEO receive lower multiples.
• Recurring revenue: Subscription or membership models command higher valuations than project‑based revenue.
• Technology and data maturity: Systems, reporting, and automation reduce perceived risk.
• Standard operating procedures: Documented processes make integration smoother and reduce uncertainty.
• Customer concentration: Heavy reliance on a few clients suppresses value unless mitigated.

Many CEOs assume that passion, hard work, and growth alone create value. In reality, buyers reward predictability, scalability, and clarity.

The CFO’s Expanded Role: From Finance Leader to Deal Architect

In modern M&A, the CFO is not just a financial steward; they are a strategic partner throughout the entire transaction. Their involvement begins long before the LOI and continues through closing and integration.

Key responsibilities include:

• Rebuilding and validating the financial story
• Identifying operational risks and opportunities
• Structuring and negotiating earnouts
• Ensuring alignment between legal language and business reality
• Protecting the seller (or buyer) from value leakage
• Translating financial insights into integration plans

Earnouts, in particular, have become increasingly common. While often viewed with skepticism, they can be powerful tools when structured correctly. The key is clarity, especially around definitions like net revenue or bad debt. Without precise language, earnouts become battlegrounds. With it, they become bridges that close valuation gaps.

Preparing for M&A Is Preparing for a Better Business

The most compelling insight from the field is this: preparing for an acquisition is simply good business. The same practices that increase valuation (clean financials, cashflow visibility, operational discipline, leadership depth) also increase profitability and resilience.

Whether a company sells in three years or never sells at all, the preparation pays dividends.

In this episode of FinFactor, host Blaine Bertsch sits down with 35-year CPA and M&A expert Holli Moeini to uncover the "crime scenes" that destroy deal value for mid-market companies. While many CEOs focus solely on revenue, Holli explains why the office of the CFO must look deeper into operational details, human judgment, and the "romance" between the P&L and the balance sheet to secure a successful exit.

Blaine and Holli discuss why 70-80% of businesses fail to sell and how proactive cash flow forecasting, GAAP-compliant records, and strategic "add-backs" can bridge the gap between a standard multiple and a premium valuation. Whether you are on the buy-side or preparing for an eventual sale, this conversation provides a roadmap for navigating working capital hurdles, managing earnouts, and building a finance function that commands trust during due diligence.
