How do you prepare a portfolio company for an M&A exit?

  • Posted by: Frédérique Pardon

To prepare a portfolio company for an M&A exit, you need to start early, build financial transparency, and remove the operational friction that causes buyers to discount their offers or walk away. The process is far more than gathering documents at the last minute. It requires structured preparation across financial reporting, governance, and team readiness, ideally beginning 12 to 24 months before a planned transaction. The questions below walk through each dimension of exit readiness in practical terms.

What does M&A exit readiness actually involve?

M&A exit readiness means getting a company to a state where it can withstand rigorous buyer scrutiny, tell a compelling value story, and close a transaction without surprises derailing the deal. It covers financial quality, operational clarity, governance structure, and the team’s ability to run a process while continuing to operate the business.

Exit readiness is not a single checklist. It is a condition the company needs to reach across several dimensions simultaneously. Buyers and their advisors will probe financial statements, customer concentration, legal compliance, management depth, and the reliability of forward projections. Any gap in these areas creates negotiating leverage for the buyer and risk for the seller.

The most important principle is this: the key question is not whether a deal can be done, but whether it should be done and whether the company is genuinely ready to deliver on the value it is claiming. Buyers pay for certainty. The more clearly a company can demonstrate the quality and sustainability of its earnings, the stronger its negotiating position.

How early should exit preparation begin?

Exit preparation should begin at least 12 to 24 months before the intended transaction. Starting earlier gives you time to fix structural issues, build a track record of clean reporting, and avoid the rushed corrections that signal to buyers that the company was not well managed.

Many founders and PE sponsors underestimate the lead time required. Financial statements need at least two to three years of clean, audited history before buyers will take them seriously as a basis for valuation. If your reporting has been inconsistent or your management accounts have been prepared informally, correcting that takes time, and buyers will notice if the cleanup happened right before the process started.

Starting early also gives you the opportunity to resolve known issues proactively. Customer contracts that are not properly documented, related-party transactions that need restructuring, or revenue recognition policies that differ from industry norms are all easier to address when you are not under deal pressure. Trying to fix these during a live process is expensive, time-consuming, and often damages buyer confidence.

What financial information do buyers expect during due diligence?

During M&A due diligence, buyers expect a comprehensive data room covering audited financial statements for at least three years, management accounts, cash flow analysis, debt and working capital schedules, tax compliance records, and detailed financial projections with clearly stated assumptions.

Beyond the basic documents, sophisticated buyers will look closely at the quality of earnings. This means they want to understand which revenues are recurring versus one-off, how margins have trended, and whether reported EBITDA reflects the true underlying performance of the business or has been inflated by accounting choices or non-recurring items.

Other information buyers consistently request includes:

  • Customer and revenue concentration analysis, showing dependence on individual clients
  • Pipeline and backlog data to support forward projections
  • Working capital trends and seasonality patterns
  • Details on any contingent liabilities, disputes, or off-balance-sheet commitments
  • Cap table, shareholder agreements, and any change-of-control provisions
  • Key employee contracts and retention arrangements

The more organized and proactively prepared this information is, the faster the process moves and the more confidence buyers develop. Disorganized or incomplete data rooms slow deals down and raise red flags about how the business has been managed.

How do you clean up financials before an M&A sale?

Cleaning up financials before an M&A sale means normalizing your earnings, eliminating one-off items, aligning accounting policies with industry standards, and ensuring your reporting is consistent, audited, and easy for an outside party to understand and verify.

Start by identifying any items in your historical financials that distort the true picture of performance. Common examples include owner salaries above market rate, personal expenses run through the business, one-time restructuring costs, or revenue from customers that no longer exist. These need to be clearly identified and adjusted in any quality of earnings analysis.

Next, review your revenue recognition policies. If you have been recognizing revenue in a way that differs from how buyers in your sector typically do it, you need to either align your approach or be prepared to explain the difference clearly. Inconsistencies here are a common source of valuation disputes.

Working capital is another area that requires attention. Buyers will negotiate a normalized working capital target as part of the deal structure. If your working capital has fluctuated significantly or if you have been managing it aggressively ahead of the sale, buyers will notice and adjust their offer accordingly. Understanding your own working capital cycle and being able to explain it clearly is essential.

What operational and governance gaps kill M&A deals?

The operational and governance gaps most likely to kill M&A deals are key-person dependency, weak internal controls, undocumented processes, compliance failures, and governance structures that give buyers pause about the reliability of the business after the founder or sponsor exits.

Key-person risk is one of the most common deal-breakers. If the business is entirely dependent on one or two individuals, and those individuals are leaving as part of the transaction, buyers face a real continuity risk. Addressing this means building a management team that can operate independently and demonstrating that the business has systems and processes that do not rely on any single person’s knowledge or relationships.

Governance issues that frequently surface in due diligence include:

  • Board minutes that are missing, incomplete, or not reflective of actual decisions made
  • Shareholder agreements with provisions that complicate a sale or transfer of ownership
  • Related-party transactions that have not been disclosed or properly documented
  • Inconsistent or informal HR practices that create employment law exposure
  • Data protection and IT security gaps, particularly relevant in tech and healthcare sectors

Operational gaps that reduce buyer confidence include a lack of scalable systems, heavy reliance on manual processes, and an inability to produce timely and accurate management information. Buyers want to see that the business can continue to perform after the transaction closes, and operational fragility directly undermines that confidence.

Who should be on the exit team for a portfolio company?

The exit team for a portfolio company should include the CEO or managing director, a CFO or senior financial lead, legal counsel with M&A experience, and an external M&A advisor with expert services who can manage the process and provide independent validation of assumptions and valuation.

The CFO role is particularly critical. The financial lead needs to be able to build and defend the financial model, manage the data room, coordinate with buyers’ advisors during due diligence, and advise on deal structure. If the company does not have a CFO with M&A experience, bringing in an interim or fractional CFO specifically for the process is a practical and increasingly common approach.

The CEO’s role is to maintain business performance and lead buyer conversations at the strategic level. One of the most common mistakes in exit processes is allowing the CEO to become so consumed by the transaction that the business underperforms during the process, which directly affects the final valuation.

Depending on the complexity of the transaction, the team may also include a tax advisor to optimize deal structure, an HR advisor to manage retention and employment issues, and sector-specific consultants if the business operates in a regulated industry. The key is assembling the team early enough that everyone understands their role before the process goes live.

How Greyt helps you prepare for an M&A exit

We work with portfolio companies and their sponsors to build genuine exit readiness, not just surface-level preparation. Our approach is built around a structured five-phase methodology that starts well before a deal goes live and continues through closing and integration.

In practice, this means we help with:

  • Finance Maturity Assessment: A structured review of your financial organization, reporting quality, and deal readiness, so you know exactly where you stand before a buyer does
  • Financial cleanup and normalization: Identifying and addressing the gaps in your historical reporting, working capital management, and accounting policies
  • Due diligence coordination: Managing the data room, responding to buyer requests, and validating assumptions so the process stays on track
  • Embedded financial leadership: Providing an experienced CFO or financial lead who can run the financial side of the transaction without pulling your management team off the business
  • Independent validation: Challenging assumptions and stress-testing the investment thesis from a CFO perspective, so you go into negotiations with a clear and defensible position

If you are planning an exit in the next one to two years, the right time to start is now. Get in touch with us to discuss where your company stands and what a structured preparation process would look like for your situation.

Frequently Asked Questions

What is the difference between a quality of earnings report and a standard audit, and do we need both?

A standard audit verifies that financial statements comply with accounting standards, while a quality of earnings (QoE) report goes deeper — it assesses whether reported earnings accurately reflect the true, sustainable performance of the business. Most sophisticated buyers will commission their own QoE report during due diligence, so commissioning a sell-side QoE in advance allows you to identify and address issues before the buyer does, giving you greater control over the narrative and reducing the risk of late-stage valuation adjustments. In most M&A transactions of meaningful size, you will need both: audited financials to establish credibility and a QoE to defend your EBITDA.

What is a realistic timeline for a full M&A exit process from preparation to closing?

From the point when preparation begins in earnest, a full M&A exit process typically takes 18 to 36 months in total — 12 to 24 months of structured preparation followed by a live deal process that usually runs 6 to 12 months from mandate to closing. The live process itself includes preparing marketing materials, running a buyer outreach process, managing management presentations and due diligence, negotiating heads of terms, and completing legal documentation. Delays most commonly occur during due diligence when financial or operational gaps are discovered, which is precisely why early preparation is so valuable.

How do we handle key-person dependency if the founder is central to the business but also planning to exit?

This is one of the most sensitive and common challenges in founder-led exits, and it needs to be addressed well before the process goes live. The practical solution is to build and empower a second tier of management — ideally 12 to 18 months ahead of the transaction — so that the business demonstrably functions without the founder's day-to-day involvement. Buyers will want to see evidence of this in management accounts, customer relationships, and operational decisions. In some cases, structuring an earnout or a transitional consulting arrangement for the founder can also help bridge buyer concerns about continuity.

What level of customer concentration is considered a red flag for buyers, and how can we mitigate it?

As a general rule, buyers become concerned when a single customer accounts for more than 15–20% of revenue, or when the top three to five customers collectively represent the majority of revenue without long-term contracts in place. Mitigation starts with diversifying the customer base over time, but if that is not possible before the transaction, the next best approach is to ensure key customer relationships are contractually secured with multi-year agreements and that the revenue is demonstrably recurring and relationship-independent rather than founder-dependent. Transparent disclosure with a clear explanation of why concentration is stable and defensible is far better than hoping buyers will not notice.

What are the most common mistakes companies make when building their data room?

The most common mistakes are disorganization, incompleteness, and reactive population — meaning documents are only added as buyers request them rather than being proactively prepared. A well-structured data room should be logically organized by category (financial, legal, commercial, HR, IT, etc.), fully indexed, and populated before the process goes live. Another frequent error is including outdated or inconsistent documents without explanation, which raises immediate red flags. Working with an experienced advisor to build the data room in advance ensures it tells a coherent story rather than creating confusion or inviting unnecessary questions.

How should we think about setting the right valuation expectation before going to market?

Valuation expectations should be grounded in a rigorous, bottoms-up analysis of your normalized EBITDA, relevant sector trading multiples, and recent comparable transaction data — not in aspirational figures or what a founder believes the business is worth. One of the most damaging mistakes in an exit process is going to market with an inflated expectation that cannot be supported by the financials, as it wastes time, erodes buyer confidence, and can permanently damage relationships with strategic acquirers. An independent CFO or M&A advisor can provide a realistic valuation range before the process begins, helping you set expectations that are ambitious but defensible.

Can a company still run a successful exit process if it has had one or two loss-making years in its recent history?

Yes, but it requires a clear, credible, and well-documented explanation of what drove the underperformance and what has structurally changed since then. Buyers are not necessarily deterred by historical losses if the narrative is honest and the recovery is evidenced in the numbers — for example, a COVID-impacted year followed by strong recovery is generally well understood. What buyers will not accept is a vague explanation, a sudden unexplained improvement right before the sale, or projections that assume a dramatic step-change without operational evidence to support them. In these situations, a sell-side QoE and a strong management presentation become especially important tools for rebuilding buyer confidence.
