Overview

• When companies evaluate a potential acquisition, financial statements tell only part of the story. Revenue may be growing, margins may look attractive, and forecasts may support the valuation, but none of that guarantees that the business can actually operate at the expected level after the transaction closes.

  This is where operational due diligence in M&A becomes important. Operational due diligence, often shortened to ODD, examines how a target company actually functions. It looks at the processes, people, technology, suppliers, facilities and organizational structures that support the financial results presented during a transaction.

  The goal is not simply to find problems. A good operational due diligence process should determine whether the target's operating model can support the investment thesis, identify risks that may affect valuation, and uncover opportunities to create additional value after closing.

  What Is Operational Due Diligence in M&A?

  Operational due diligence is a structured review of the operating capabilities and risks of a target company before an acquisition or investment.

  Unlike financial due diligence, which concentrates primarily on earnings quality, cash flow, liabilities and financial performance, operational diligence asks a different set of questions:

  • How efficiently does the business operate?
  • Are its processes scalable?
  • How dependent is it on particular employees or suppliers?
  • Can current systems support future growth?
  • Are projected cost savings realistic?
  • How much investment will be required after the acquisition?
  • What operational problems could disrupt customers or reduce profitability?

  EY describes operational due diligence as an assessment that goes beyond financial analysis to evaluate the capabilities, risks and value drivers underlying a target business. Typical areas include the operating model, cost structure, supply chain, R&D and selling, general and administrative functions.

  In practical terms, ODD helps buyers understand whether the business they are buying can deliver what the financial model assumes.

  Why Operational Due Diligence Matters

  A company can appear attractive financially while carrying significant operational weaknesses.

  Consider a manufacturer reporting strong EBITDA growth. Further investigation might reveal that most production depends on one aging facility that requires substantial capital expenditure within two years.

  A software company may have strong recurring revenue but depend on a small development team responsible for critical legacy systems.

  A retailer may appear highly profitable but rely on a single logistics provider or an unusually favorable warehouse contract that will expire shortly after closing.

  These issues may not immediately appear in a financial model, yet they can materially change the economics of the transaction.

  Operational due diligence helps convert such findings into specific financial implications:

  Operational issue → business impact → financial impact → deal decision

  For example:

  Warehouse capacity is nearly exhausted → additional distribution center required → $8 million of unplanned capital expenditure → purchase price or investment case needs adjustment.

  That connection between operational reality and transaction economics is one of the most important functions of ODD.

  Key Areas of Operational Due Diligence

  The exact scope depends on the industry and deal thesis, but several areas appear in most operational reviews.

  Operating Model

  The operating model explains how the organization turns its strategy into day-to-day activity.

  Due diligence should examine:

  • organizational structure;
  • decision-making responsibilities;
  • centralized versus decentralized functions;
  • management layers;
  • shared services;
  • outsourcing arrangements;
  • performance-management processes.

  Buyers should determine whether the existing operating model is suitable for the expected future business.

  This becomes particularly important when two companies will be integrated. McKinsey notes that M&A transactions often require changes to organizational structures, processes, talent and behaviors to achieve the objectives of the combined company.

  Cost Structure

  Understanding expenses means going deeper than the income statement.

  The diligence team should determine which costs are:

  • fixed;
  • variable;
  • discretionary;
  • temporary;
  • contractually committed;
  • likely to increase;
  • potentially removable after the transaction.

  A company may report attractive margins because it has postponed maintenance, technology upgrades or hiring.

  Those expenses do not disappear. They become obligations for the new owner.

  The analysis should therefore distinguish between reported profitability and sustainable profitability.

  Supply Chain and Procurement

  Supply-chain risk can have an immediate effect on deal value.

  Areas to investigate include:

  • supplier concentration;
  • critical single-source suppliers;
  • contract duration;
  • purchasing terms;
  • lead times;
  • inventory levels;
  • alternative suppliers;
  • geographical exposure;
  • logistics arrangements;
  • commodity-price sensitivity.

  A business dependent on one critical supplier represents a very different operational risk from a company with a diversified supplier base.

  Procurement can also provide value-creation opportunities. A strategic buyer may obtain better pricing by combining purchasing volumes with the target.

  Production and Capacity

  For manufacturing and asset-intensive businesses, operational diligence should examine whether current facilities can support the business plan.

  Questions may include:

  • What is current capacity utilization?
  • Where are production bottlenecks?
  • How much unused capacity remains?
  • What maintenance has been deferred?
  • When will new equipment be required?
  • What capital expenditure is necessary?
  • How efficient is production compared with industry benchmarks?

  If management forecasts revenue doubling over five years while production is already operating at 95% capacity, significant additional investment is likely to be required.

  Technology and Systems

  Technology increasingly forms part of operational due diligence even when the target is not a technology company.

  The buyer should understand the systems supporting:

  • finance;
  • inventory;
  • customer relationships;
  • manufacturing;
  • procurement;
  • HR;
  • reporting;
  • data management.

  Important questions include whether systems are scalable, properly supported and integrated.

  Legacy technology can create significant post-deal costs.

  For example, an acquisition may require migration from an outdated ERP platform, consolidation of multiple CRM systems or replacement of unsupported software.

  Technology assessment should also consider cybersecurity, data quality and system resilience, although a detailed cyber review may be performed as a separate diligence workstream.

  People and Organizational Risk

  Operations depend on people.

  A business may have documented processes and sophisticated systems but still rely heavily on a small number of employees.

  Operational due diligence should identify:

  • key managers;
  • specialized technical employees;
  • succession risks;
  • employee turnover;
  • skills shortages;
  • management depth;
  • compensation issues;
  • recruitment challenges.

  One important question is:

  What happens if the five most important employees leave immediately after closing?

  If the answer is that the company would struggle to operate, retention planning should begin before the transaction closes.

  Customer Operations

  ODD should also examine how the business serves customers.

  This may include:

  • customer onboarding;
  • order fulfillment;
  • delivery performance;
  • service quality;
  • customer support;
  • complaint management;
  • returns;
  • service-level agreements.

  Operational problems can reveal risks that have not yet appeared in the financial statements.

  Growing customer complaints, for example, may eventually result in declining retention and revenue even if historical financial performance remains strong.

  Testing the Business Plan

  One of the most valuable uses of operational due diligence is testing management's forecast.

  Suppose management expects:

  • revenue growth of 20% per year;
  • improved gross margins;
  • reduced operating expenses;
  • no major increase in capital expenditure.

  Operational diligence should examine whether those assumptions can coexist.

  Can the sales organization generate the expected growth?

  Can production handle additional volume?

  Can the supply chain support it?

  Does the company need more employees?

  Will warehouses require expansion?

  Will IT systems handle twice as many transactions?

  If the answer to several of these questions is no, the business plan may be financially attractive but operationally unrealistic.

  Identifying Synergies

  Operational due diligence is also important for evaluating M&A synergies.

  Potential cost synergies may include:

  • procurement savings;
  • facility consolidation;
  • elimination of duplicate functions;
  • shared services;
  • logistics optimization;
  • technology consolidation;
  • reduced management overhead.

  Revenue opportunities may involve:

  • cross-selling;
  • expanded distribution;
  • new geographical markets;
  • combined product offerings.

  However, projected synergies should be tested carefully.

  It is not enough to say that both businesses have finance departments and therefore half of the combined finance organization can be eliminated.

  The diligence team needs to understand which activities are actually duplicated, what systems each company uses and what resources the future operating model will require.

  Experienced acquirers often look beyond simple cost reductions and use transactions to redesign shared services, operating models and business processes.

  Integration Readiness

  Operational due diligence should not end with a list of risks.

  Its findings should influence integration planning.

  Before closing, the buyer should understand what needs to happen:

  Day One

  Operations must continue without disruption.

  Customers need to receive products and services. Employees need access to systems. Suppliers need to know where to send invoices.

  First 100 Days

  Early integration priorities may include management changes, governance, procurement initiatives, reporting processes and retention measures.

  Longer Term

  More complex initiatives may involve technology migration, facility consolidation, organizational redesign or supply-chain restructuring.

  This connection between diligence and integration is critical.

  McKinsey notes that effective integration planning covers organizational design, talent, technology, culture and operational processes rather than treating integration as a purely financial exercise.

  Common Operational Due Diligence Red Flags

  No business is perfect, and identifying a red flag does not automatically mean the transaction should stop.

  However, certain findings deserve close attention:

  • extreme dependence on one supplier;
  • significant deferred maintenance;
  • undocumented critical processes;
  • outdated or unsupported IT systems;
  • high employee turnover;
  • dependence on one or two executives;
  • capacity constraints inconsistent with growth projections;
  • unusually high inventory;
  • poor operational KPIs;
  • weak management reporting;
  • substantial unplanned capital expenditure;
  • recurring customer-service problems;
  • unrealistic synergy assumptions.

  The important question is not simply whether these issues exist.

  The buyer needs to understand how much they will cost to fix and whether they change the investment thesis.

  Operational Due Diligence Checklist

  A practical ODD review may cover:

  Organization

  • structure and management;
  • key employees;
  • decision-making;
  • headcount;
  • outsourcing.

  Operations

  • major processes;
  • productivity;
  • capacity;
  • quality;
  • facilities.

  Supply Chain

  • suppliers;
  • procurement;
  • logistics;
  • inventory;
  • concentration risks.

  Technology

  • ERP and operational systems;
  • infrastructure;
  • integrations;
  • scalability;
  • technical debt.

  • maintenance requirements;
  • growth investments;
  • deferred expenditure.

  Integration

  • synergy opportunities;
  • one-time integration costs;
  • Day One requirements;
  • operating-model changes.

  From Findings to Deal Decisions

  The final operational due diligence report should not simply contain hundreds of observations.

  The most useful output organizes findings around their effect on the transaction.

  Each major issue should answer four questions:

  1. What did we find?
  2. Why does it matter?
  3. What is the financial impact?
  4. What action should the buyer take?

  Potential responses may include:

  • adjusting valuation;
  • changing the purchase agreement;
  • requesting additional warranties;
  • changing synergy assumptions;
  • increasing the integration budget;
  • requiring management retention agreements;
  • creating a post-closing improvement plan;
  • walking away from the transaction.

  In this way, operational due diligence becomes part of the investment decision rather than simply another diligence checklist.

  Final Thoughts

  Operational due diligence in M&A is ultimately about determining whether the operational reality of a business supports the story presented in the deal model.

  Financial due diligence may establish what the company has earned. Commercial due diligence may assess whether customers and markets can support future growth. Operational due diligence asks whether the organization can actually deliver that growth.

  The strongest ODD processes combine risk assessment with value creation. They identify weaknesses, quantify the cost of fixing them, test management forecasts, evaluate synergies and begin shaping the post-deal operating model before closing.

  For buyers, private equity investors and corporate development teams, that can make the difference between acquiring a business that looks attractive on paper and acquiring one that can actually deliver the expected returns.
