Every M&A deal in Oman starts to look simple on paper and gets complicated the moment someone opens the target company’s books. A share purchase agreement can be drafted in a week. Understanding what you are actually buying, legally, financially, and operationally, takes far longer, and skipping that step is where most cross-border deals in the Sultanate run into trouble. Between sector-specific approvals, a foreign investment framework that treats certain industries differently from others, and a merger control regime that requires clearance before a deal can close, the due diligence process Oman investors need to follow is more structured than many first-time buyers expect.
This article walks through that process from the first engagement letter to post-completion integration, with a focus on what actually needs to happen at each stage rather than generic best practice. It draws on the kind of transaction issues MFN Auditing regularly helps clients work through when entering or expanding in the Omani market.
Why Due Diligence Looks Different in Oman
Oman’s regulatory environment has shifted considerably since the Foreign Capital Investment Law (Royal Decree 50/2019) came into force, opening most sectors to 100% foreign ownership. That liberalization is real, but it did not remove the layers of approval that still sit underneath many transactions. Banking targets need Central Bank of Oman clearance. Investment funds and brokerages need Capital Market Authority approval. Utilities and electricity companies need sign-off from the Authority for Electricity Regulation. Deals that create market dominance need clearance from the competition regulator before they can legally close.
None of this makes Oman a difficult place to transact. It makes due diligence in Oman a genuinely regulatory exercise, not just a financial and legal box-ticking exercise borrowed from a Western M&A playbook. A due diligence process built for a UK or US deal, and simply translated for the Omani market, will miss half of what actually determines deal risk here.
Stage 1: Pre-Diligence Planning
Before any documents are requested, the buy side needs to answer a few questions that shape everything downstream.
What sector does the target operate in, and does that sector carry ownership restrictions?
Oman maintains a Negative List under Ministerial Decision 209/2020 that restricts full foreign ownership in specific activities. Some sectors, including oil and gas, construction, tourism, banking, and mining, require a local shareholder holding at least 30%, unless the Ministry of Commerce, Industry and Investment Promotion approves a reduction. Confirming this early determines whether the deal structure needs a joint venture from day one.
Does the deal trigger merger control notification?
Under the Competition Protection and Monopoly Prevention Law (Royal Decree 67/2014), any transaction that could result in a party acquiring a dominant market position, generally interpreted as more than 50% of the relevant market, must be notified to the regulator before completion. The regulator has 90 days to respond, and the deal is deemed approved if it does not respond within that window.
Will the target need a sector regulator’s approval for change of control?
Banks, investment firms, brokerages, and electricity companies all sit under separate regulatory approval requirements. These approvals are not a formality. They involve the regulator reviewing the acquirer’s financial standing, ownership structure, and sometimes its ultimate beneficial owners, so they need to start early in parallel with commercial diligence rather than after signing.
Getting clear answers to these three questions shapes the scope, timeline, and team composition for everything that follows.
Stage 2: Assembling the Diligence Team
Because Omani due diligence spans legal, financial, tax, regulatory, and often technical or environmental workstreams, most serious transactions bring in a mix of internal deal leads and external specialists rather than trying to run it all in-house. A typical team includes:
- Legal counsel with Omani corporate and regulatory experience, to handle the Commercial Companies Law, licensing, and sector approvals
- Financial due diligence specialists, usually an audit or advisory firm, to validate the target’s numbers
- Tax advisors familiar with Oman’s corporate tax rules, withholding tax exposure, and increasingly, the incoming personal income tax framework for 2028
- HR and labor advisors, given Oman’s Omanisation quotas and the requirement, in force since April 2026, for foreign-owned businesses to employ at least one Omani national within a year of starting operations
- Sector specialists where relevant, such as environmental consultants for industrial targets or IT auditors for tech-heavy acquisitions
Buyers who try to run this process with a single generalist advisor typically end up re-doing work later, once gaps surface that a specialist would have caught the first time.
Stage 3: Legal Due Diligence
Legal diligence in Oman covers the same broad categories as most jurisdictions, corporate standing, contracts, litigation, and IP, but with a few areas that deserve extra attention locally.
Corporate Structure and Licensing
The starting point is confirming the target’s registration with the Ministry of Commerce, Industry and Investment Promotion, its commercial register extract, and its Foreign Capital Investment Law status if it already has foreign shareholders. Buyers should verify that all required sector licenses are current, that share capital requirements have actually been met (not just declared), and that there are no pending disputes over ownership.
Material Contracts
Reviewing customer, supplier, financing, and lease agreements matters everywhere, but in Oman it is worth paying particular attention to change-of-control clauses. Many long-term government and semi-government contracts, which are common in Oman’s oil and gas, construction, and infrastructure sectors, include termination or renegotiation rights triggered by a change in ownership. Missing one of these clauses can turn a clean acquisition into a target that loses its most valuable contract the day the deal closes.
Litigation and Regulatory Compliance History
This includes checking for pending court cases, labor disputes, and any history of regulatory penalties, particularly under the Competition Law, environmental regulations, or sector-specific licensing conditions. A target with unresolved regulatory issues can pass its liabilities directly to the acquirer.
Stage 4: Financial Due Diligence
Financial due diligence in Oman engagements typically follows the standard structure of quality of earnings, working capital analysis, and net debt review, but a few local factors change how that analysis needs to be read.
Oman introduced VAT in 2021, and reviewing VAT compliance history, including filing accuracy and any outstanding assessments, is now a standard part of financial diligence. Corporate income tax exposure is checked against the target’s actual tax filings rather than management’s representations alone, since the Oman Tax Authority has become more active in recent years. And because Oman’s Social Protection Fund contribution rules changed substantially in 2023, and continue to be phased in for expatriate employees through 2027 and 2028, buyers should confirm that payroll contributions are calculated correctly and that there is no accumulated liability quietly on the balance sheet.
Working capital normalization also needs local context. Payment terms with government and semi-government counterparties in Oman can run considerably longer than commercial norms elsewhere in the Gulf, which affects how a buyer should interpret the target’s receivables aging and cash conversion cycle.
Stage 5: Tax and Regulatory Due Diligence
This stage deserves its own line of work rather than being folded into general financial diligence, because Oman’s tax and regulatory landscape is moving quickly. Key areas to cover include:
- The target’s corporate income tax position and any unresolved assessments from the Oman Tax Authority
- Withholding tax exposure on cross-border payments to foreign shareholders, lenders, or service providers
- VAT compliance history and customs duty treatment for any imported goods
- Exposure to Oman’s upcoming Personal Income Tax Law, effective 1 January 2028, which will require payroll withholding for employees earning above OMR 42,000 a year
- Whether any sector-specific approvals the target holds transfer automatically on a share sale, or need to be re-applied for under the new ownership
For a target with a high-earning management team, the 2028 tax transition is not a distant issue. It is a cost that needs to be modeled into post-acquisition projections now, alongside whatever pre-completion notifications the deal itself may need to a sector regulator or the competition authority.
Stage 6: Operational and Commercial Due Diligence
Beyond the numbers and the paperwork, buyers need a clear view of how the business actually runs day to day. This typically covers:
- Management and workforce: the quality and retention risk of the leadership team, and how dependent the business is on a small number of key people
- Customer and supplier concentration: whether revenue or supply relies heavily on a handful of relationships that could be disrupted by a change in ownership
- Physical assets: condition and maintenance history for asset-heavy businesses, including any equipment nearing end of life
- IT systems and cybersecurity: particularly for any target handling customer data or operating critical infrastructure
- Omanisation compliance: whether the target meets its sector’s required ratio of Omani national employees, since a shortfall can lead to penalties or restrictions on work permit renewals after the deal closes
Stage 7: Deal Structuring and Regulatory Approvals
Once diligence findings are in, the deal team needs to translate them into structure and documentation. This is where the Negative List restrictions, sector ownership limits, and merger control thresholds identified in Stage 1 get finalized into the actual transaction structure, whether that is a straightforward share purchase, an asset deal, or a joint venture with a local partner holding the required minimum stake.
Regulatory approvals should be filed as early as the deal timeline allows, since sector regulator reviews and competition clearance can run in parallel with final documentation but rarely move faster than their statutory timeframes. A deal that assumes a 90-day competition clearance can be compressed to satisfy an aggressive closing date is usually a deal that ends up delayed.
Stage 8: Post-Completion Integration
Due diligence does not end at signing. The findings from each workstream should feed directly into a post-completion action plan, correcting payroll contribution shortfalls, renegotiating contracts with problematic change-of-control clauses, closing out any Omanisation quota gaps, and putting a plan in place for the 2028 income tax transition if the target has employees who will cross the threshold.
Buyers who treat diligence purely as a pre-signing exercise, rather than a source of an integration roadmap, tend to lose much of the value that diligence was supposed to create.
When to Bring in Specialist Due Diligence Services
Given how many regulatory threads run through a single Omani transaction, most acquirers, particularly those entering the market for the first time, choose to work with specialist due diligence services in Oman rather than assembling every capability independently. A local advisor who understands the interplay between the Foreign Capital Investment Law, sector regulator approval processes, and the Competition Law can often identify deal-breaking issues in the first two weeks of diligence that would otherwise surface only after signing, when they are far more expensive to fix.
Making Due Diligence Work for Oman Deals
Due diligence in Oman rewards buyers who treat it as a regulatory process first and a financial exercise second. The Sultanate’s ownership rules, sector approvals, competition clearance requirements, and evolving tax and social protection framework all shape deal risk in ways that a generic international checklist will not catch. Building a diligence process around Oman’s actual legal and regulatory structure, starting with the right questions before a single document is requested, is what separates a deal that closes on schedule from one that stalls in regulatory review or unravels after completion.
This is the kind of process MFN Auditing works through with clients on a regular basis, helping buyers move from initial deal planning through legal, financial, and regulatory diligence, and into a post-completion plan that reflects what diligence uncovered. For investors weighing a deal in Oman, getting this structure right from the outset is what turns due diligence from a compliance step into a genuine source of deal confidence.
Frequently Asked Questions
How long does the due diligence process typically take for an M&A deal in Oman?
- Straightforward, single-sector deals with no regulatory approval needed: roughly 4 to 6 weeks
- Deals requiring sector regulator clearance (banking, capital markets, electricity): 8 to 12 weeks, driven by the regulator’s own review timeline
- Deals triggering competition law notification: add up to 90 days for the regulator’s statutory response window, though it can move faster if no concerns arise
Is foreign ownership always capped in Oman?
No. Most sectors allow up to 100% foreign ownership under the Foreign Capital Investment Law. Restrictions only apply to activities listed on the Negative List, which includes sectors like oil and gas, construction, tourism, banking, and mining, where a local shareholder holding at least 30% is generally required unless the Ministry of Commerce, Industry and Investment Promotion approves an exception.
What happens if a deal closes without required regulatory approval?
Completing a transaction that needed sector regulator or competition authority clearance without obtaining it can expose the deal to being unwound, fines, or the acquirer being unable to register the change of ownership with the relevant authority. It can also complicate future licensing or approval requests for the acquiring entity.
Do private, non-listed target companies require the same level of due diligence as listed ones?
Yes, in most respects. While listed companies carry additional Capital Market Authority disclosure obligations, private targets still carry the same legal, financial, tax, and regulatory risks.
