The Role of Due Diligence in Nigerian Business Acquisitions

Let me tell you something about failed acquisitions that every Nigerian business leader should know.

Every Nigerian business acquisition that has gone badly wrong has a due diligence story at its center.

Sometimes the due diligence was inadequate. Conducted too quickly. With too narrow a scope. With insufficient access to the information that would have revealed the problem.

Sometimes the due diligence was technically adequate, but the findings were rationalised away. An acquisition team became emotionally committed to completing the transaction and treated the due diligence process as a compliance exercise rather than a genuine risk assessment.

And sometimes the due diligence was thorough and honest, but the findings were presented to a board that lacked the governance discipline to walk away from a transaction whose problems the due diligence had clearly identified.

The pattern across all of these failed acquisition stories is the same. The information needed to make a better decision was either not gathered, not understood, not presented, or not acted upon.

Due diligence is the process through which acquirers gather and assess the information they need to make informed acquisition decisions. In the Nigerian context, that process carries specific demands that make it more challenging than standard international due diligence frameworks anticipate.

The information environment for Nigerian private companies is less transparent. The governance quality is more variable. The regulatory compliance record is more complex. And the specific risks of the Nigerian operating environment are more numerous than due diligence frameworks developed for more developed market contexts address.

This article examines what comprehensive due diligence for Nigerian business acquisitions requires, where the most significant risks are concentrated, and how Nigerian acquirers can build due diligence processes that genuinely protect them from the acquisition risks that the Nigerian market presents.

What due diligence actually is and why its definition matters

Due diligence is one of the most frequently referenced and most frequently misunderstood concepts in Nigerian M&A practice. Its misunderstanding produces due diligence processes that are too narrow in scope, too shallow in depth, or too disconnected from the actual acquisition decision.

According to Investopedia, due diligence is defined as “an investigation, audit, or review performed to confirm facts or details of a matter under consideration. In the financial world, due diligence requires an examination of financial records before entering into a proposed transaction with another party.”

Due diligence has expanded beyond financial matters and now encompasses legal, regulatory, commercial, operational, environmental, and governance dimensions of a proposed transaction. The purpose of due diligence is to provide the buyer with sufficient information to make an informed decision about whether to proceed with the transaction, on what terms, and with what risk mitigation measures.

The four purposes of due diligence in Nigerian acquisitions.

Information verification is the most commonly understood purpose. Confirming that the information the seller has represented about the business is accurate. Revenue and profitability claims. Asset values. Customer base characteristics. Employee numbers and contracts. Regulatory license status. All are factual representations that due diligence should verify.

Risk identification goes beyond verifying what the seller has represented. It identifies risks that the seller has not represented, either because those risks were not disclosed, were not known to the seller, or were framed in ways that obscured their commercial significance. Nigerian acquisition due diligence routinely identifies material risks that were not in the information memorandum: undisclosed liabilities, regulatory compliance failures, pending litigation, tax obligations that have not been properly reserved for, and governance failures that create post-acquisition liability.

Valuation support provides the evidence base for the acquirer’s valuation of the target business. Due diligence findings that reveal earnings quality problems, overstated assets, understated liabilities, or one-time revenue items that distort reported profitability support downward revision of the acquisition price.

Transaction structure and protection design uses due diligence findings to inform the specific warranties, representations, indemnities, and transaction structure protections that the acquirer should require in the acquisition agreement.

The strengthening of Nigerian regulatory enforcement across multiple sectors has elevated the regulatory compliance dimension of Nigerian acquisition due diligence significantly compared to previous years. Acquirers that conducted Nigerian acquisitions without comprehensive regulatory compliance due diligence are in some cases discovering post-acquisition regulatory issues that are materially more expensive to remediate.

The specific challenges of due diligence in the Nigerian context

Standard international due diligence frameworks must be adapted for Nigerian conditions.

The information quality challenge.

Nigerian privately held companies are not subject to the financial disclosure requirements that publicly listed companies face. Their financial statements may not be audited to the standards of major international accounting firms. They may reflect accounting policies that prioritise tax minimisation over accurate financial representation. And they may not include the consolidation of related party entities.

The information quality challenge requires specific approaches to verify financial information that cannot simply be accepted at face value. Cross-referencing financial statements against bank statements, tax filings, supplier and customer correspondence, and operational records provides independent verification.

The undisclosed liability challenge.

Nigerian businesses, particularly family-owned enterprises and businesses that have not been subject to formal audit and governance requirements, frequently carry undisclosed liabilities that due diligence must systematically search for.

The most common categories include unremitted statutory deductions including PAYE tax, pension contributions, and NSITF levies collected from employees but not remitted. Outstanding tax liabilities not fully provided for in financial statements. Legal claims in early stages or not formalised. Related party transactions creating obligations not visible in standalone financial statements. And environmental or regulatory compliance obligations not formally assessed.

Identifying these requires specific due diligence procedures beyond reviewing disclosed financial statements. Direct enquiries with tax authorities. Legal proceedings searches. Regulatory compliance reviews. Environmental assessments where relevant. And related party transaction analysis mapping all entities and individuals with commercial relationships with the target.

The corporate governance quality challenge.

The corporate governance quality of Nigerian acquisition targets varies enormously. From well-governed private equity-backed businesses with professional boards, independent auditors, and documented policies, to informally managed family businesses where governance is entirely personal and undocumented.

Assessing governance quality is not simply checking whether formal governance structures exist. It is understanding whether those structures actually function as governance mechanisms. Due diligence must assess governance quality through behavioral evidence including the quality and consistency of board minutes, the independence of the external auditor and the quality of their audit management letter, the existence and enforcement of documented policies for key risk areas, and the patterns of management decision-making visible in operational and financial records.

The related party transactions challenge.

Nigerian family businesses and closely controlled private companies commonly engage in related party transactions. Value is transferred between the business and its owners, their families, or their connected entities in ways that may not be fully visible in the reported financial statements.

Common forms include rental of business premises from a related entity at above-market rates. Procurement from related party suppliers at above-market prices. Sales to related party customers at below-market prices. Management fees paid to related party entities for services whose value is not proportionate to their cost. And inter-company loans and guarantees creating contingent liabilities.

Identifying and analysing related party transactions requires mapping all entities and individuals with ownership, management, or commercial relationships with the target. Examining all significant contracts and transactions for related party involvement. And assessing whether identified related party transactions are at arm’s-length terms that will be maintained post-acquisition.

For support with risk identification, our acquisition target screening and strategic fit assessment can help.

The due diligence work streams for Nigerian business acquisitions

Comprehensive acquisition due diligence requires multiple specialist work streams working in coordination.

Financial due diligence.

Financial due diligence is the most familiar and extensively practiced work stream. In the Nigerian context, it must address several specific requirements.

Quality of earnings analysis adjusts reported financial performance to identify sustainable, recurring earnings representing the true underlying profitability. This removes one-time income items that inflate reported profitability, adds back excessive management remuneration or related party costs, identifies accounting policy choices that have accelerated income recognition, and normalises reported earnings for economic conditions.

Working capital analysis assesses the working capital requirements of the business and whether the target’s working capital position at completion will meet agreed targets. Nigerian businesses with seasonal sales patterns, with significant credit sales to customers with variable payment behavior, and with inventory subject to price volatility require careful analysis.

Cash flow analysis traces actual cash generation and consumption over the due diligence period, independent of accrual accounting financial statements. Comparing reported profitability to actual cash generation frequently reveals earnings quality issues and working capital absorption not visible in the income statement.

Balance sheet analysis assesses the quality and recoverability of reported assets and the completeness of reported liabilities. Asset quality issues commonly include overvalued property, accounts receivable with old balances not genuinely recoverable, inventory including slow-moving or obsolete stock, and goodwill or intangible assets whose value depends on unsupported assumptions.

Legal due diligence.

Legal due diligence must address the legal framework of the transaction itself, the legal standing and compliance of the target business, and the specific legal risks that the Nigerian legal environment creates.

Corporate legal due diligence verifies legal existence and good standing, confirms shares are validly issued and properly owned by purported sellers, identifies any restrictions on share transfer including pre-emption rights and change of control provisions, and confirms board and shareholder approvals are properly obtained.

Material contract review examines key commercial contracts including customer contracts, supplier agreements, distribution agreements, lease arrangements, and financing agreements. It identifies contracts containing change of control provisions that could be triggered by the acquisition, contracts terminable in ways that would significantly affect post-acquisition commercial position, and contracts whose terms materially differ from acquirer assumptions.

Employment law due diligence assesses compliance with Nigerian employment law requirements, including proper documentation of employment contracts, compliance with minimum wage requirements, proper remittance of statutory deductions, and compliance with collective agreement terms where trade unions are present.

Litigation and dispute due diligence identifies all current, threatened, and reasonably foreseeable legal proceedings, assesses likely outcomes and financial implications, and identifies patterns of dispute involvement reflecting ongoing commercial or operational risk.

Tax due diligence.

Tax due diligence addresses one of the most significant sources of undisclosed liability. The complexity of Nigeria’s tax system, the frequency with which Nigerian businesses are not fully compliant, and the tendency of tax liabilities to accumulate for years create material tax risk.

Corporate income tax due diligence reviews corporation tax returns and assessments, assesses completeness and accuracy of reported taxable income, identifies deductions that may not withstand FIRS scrutiny, and estimates potential exposure from identified issues.

Value Added Tax due diligence reviews VAT registration, filing compliance, and remittance history. Businesses that have been making taxable supplies without proper VAT registration, under-remitting VAT collected, or making incorrect VAT claims create VAT liabilities.

Withholding tax due diligence assesses whether the target has properly withheld and remitted withholding tax on payments to contractors, consultants, and related parties. Withholding tax non-compliance is among the most common issues discovered.

Transfer pricing due diligence is relevant for targets with related party transactions with offshore entities, assessing whether transactions have been conducted at arm’s-length prices and whether appropriate transfer pricing documentation exists.

Regulatory and compliance due diligence.

Regulatory and compliance due diligence assesses whether the target has met its obligations under all applicable regulatory frameworks.

Sector regulatory due diligence verifies the status of all regulatory licenses and permits, confirms their validity, identifies any conditions attached, and assesses whether there are pending regulatory actions affecting their continuation.

CBN and financial sector compliance for fintech and financial institution acquisitions must assess AML and KYC compliance, consumer protection compliance, capital adequacy, and the history of regulatory interactions.

NAFDAC compliance for pharmaceutical and food sector acquisitions must assess product registration compliance, manufacturing facility standards, and the history of NAFDAC interactions.

NDPA compliance for businesses that process significant personal data must assess the adequacy of data protection policies, security measures, and the history of any data incidents.

Commercial and operational due diligence.

Commercial due diligence assesses the quality and sustainability of the target’s commercial position. The strength and loyalty of its customer base. The quality of its supplier relationships. The defensibility of its competitive position. And the realistic growth prospects.

Customer base analysis examines revenue concentration, the tenure and loyalty of key customer relationships, contractual terms, and the commercial history of each significant customer relationship including the trajectory of their spending.

Operational due diligence assesses physical assets, operational processes, technology systems, and workforce capability. For manufacturing acquisitions, this includes physical inspection of production facilities, equipment assessment, maintenance record review, and production efficiency analysis.

Environmental and social due diligence has become more broadly relevant as ESG considerations have become more central to investor evaluation of Nigerian businesses. Nigerian acquirers with international investors or financing should ensure their due diligence programmes include ESG assessment proportional to the target’s footprint.

Organising and managing the Nigerian acquisition due diligence process

Due diligence that is poorly organised produces findings that are incomplete, contradictory, and difficult to act on.

The due diligence team.

Comprehensive due diligence requires a coordinated team of specialists whose work is managed by a lead advisor who maintains oversight of all work streams and synthesises findings into a coherent overall risk assessment.

The financial due diligence team should be led by an experienced transaction services firm with demonstrated Nigerian market experience and should include accountants with specific expertise in the target’s industry sector.

The legal due diligence team should be led by a Nigerian law firm with corporate M&A experience and should include specialists in employment law, regulatory law, and property law as required.

Tax due diligence should be conducted by tax specialists with FIRS engagement experience and knowledge of specific tax issues most common in the target’s sector.

Regulatory due diligence should engage specialists familiar with the specific regulatory frameworks applicable to the target.

Coordination requires a due diligence workplan defining scope, approach, and timeline for each work stream. A data room management process ensuring all teams have access to needed information. Regular cross-team coordination calls surfacing issues requiring input from multiple work streams. And a finding consolidation process ensuring the overall due diligence report presents an integrated view of risks.

The data room and information access.

The quality of due diligence is fundamentally constrained by the quality and completeness of the information made available to the due diligence team. Nigerian targets vary significantly in their ability and willingness to provide comprehensive, well-organised information.

The due diligence information request should be comprehensive and specific. Information requests that are vague or incomplete produce selective information provision, allowing the seller to provide what is favourable while omitting what is not.

Virtual data rooms that provide controlled digital access to transaction documents have become increasingly standard, providing better document management, better access control, and better audit trails.

Red flags and deal breakers.

The due diligence team must maintain a clear distinction between findings that are deal breakers, findings that require price adjustment or transaction structure protection, and findings that require post-acquisition remediation planning.

Deal breaker findings include fundamental misrepresentations undermining the strategic rationale for the acquisition. Undisclosed liabilities material relative to the acquisition price. Regulatory compliance failures that would prevent the combined entity from operating the business legally. And governance failures indicating a risk of fraud or financial misappropriation that the acquirer cannot mitigate.

The organisational discipline to act on deal breaker findings by withdrawing from the transaction is one of the most important governance capabilities that Nigerian acquirers must build. The sunk cost of a due diligence process is not a reason to complete an acquisition that due diligence has demonstrated is not in the acquirer’s interest.

For support with deal breaker assessment, our acquisition decision advisory based on due diligence findings can help.

Those that treat due diligence as a compliance step to be completed quickly and cheaply are accumulating exposure to undisclosed liabilities, regulatory failures, governance problems, and commercial misrepresentations.

Start by defining your due diligence scope. Then assemble your team. Then access information. Then synthesise findings. Then make disciplined decisions.

The companies that master due diligence will be the ones that succeed in Nigerian M&A.
