Mergers and Acquisitions in Turkey: A Strategic Guide for Foreign Investors and MNCs in 2026

Mergers and acquisitions in Turkey have surged to the forefront of cross-border deal-making as multinational corporations, private equity funds, and high-net-worth individuals seek strategic entry into one of the world’s most dynamic emerging markets. With a domestic consumer base exceeding 85 million, a geographic position bridging Europe and Asia, and a regulatory framework that has undergone significant reform in early 2026, Turkey presents compelling — yet complex — opportunities for foreign acquirers. The Turkish Competition Board’s February 2026 amendment to the merger control communiqué has fundamentally recalibrated notification thresholds, making it essential for every foreign investor to understand the new landscape before committing capital.
For C-level executives evaluating acquisition targets in Istanbul, Ankara, or Izmir, the stakes extend far beyond purchase price. Turkish M&A transactions implicate competition law clearances, sector-specific regulatory approvals, tax structuring imperatives, employment transfer obligations, and — increasingly — data protection compliance under KVKK. Istanbul Attorneys, through our corporate and commercial law practice and the Lexin Legal strategic alliance spanning 40+ countries, provides the full-spectrum legal architecture that sophisticated cross-border acquirers demand.
Key Takeaways: M&A in Turkey for Foreign Investors
The Turkish Competition Board’s February 2026 amendment raised cumulative local turnover thresholds to TRY 3 billion and individual thresholds to TRY 1 billion — a fourfold increase from prior levels.
Technology sector acquisitions retain a lower notification threshold of TRY 250 million for Turkish-established targets, reflecting heightened regulatory scrutiny of digital economy consolidation.
Foreign investors may acquire 100% of Turkish companies in most sectors under the Foreign Direct Investment Law (Law No. 4875), with no general foreign ownership caps.
Strategic sectors including defence, energy, telecommunications, banking, and media require sector-specific regulatory approvals beyond Competition Board clearance.
Phase I Competition Board review typically concludes within 30 calendar days; Phase II in-depth investigations can extend up to 6 months.
The Regulatory Framework for M&A Transactions in Turkey
Turkish Competition Law and Merger Control
Turkey’s merger control regime is governed by the Competition Law (Law No. 4054) and Communiqué No. 2010/4 on Mergers and Acquisitions Requiring the Approval of the Competition Board. The Turkish Competition Authority (TCA) exercises exclusive jurisdiction over merger clearance, and no transaction that meets notification thresholds may be completed without prior approval. Transactions closed without mandatory clearance are deemed legally void — a risk that no sophisticated foreign investor can afford to take.
The February 2026 amendment to Communiqué No. 2010/4 represents the most significant overhaul of Turkish merger control thresholds in over a decade. The revision quadrupled the individual Turkish turnover threshold from TRY 250 million to TRY 1 billion, while cumulative Turkish turnover thresholds rose from TRY 750 million to TRY 3 billion. These increases reflect both Turkish lira depreciation and the TCA’s policy objective of focusing enforcement resources on transactions with genuine competitive significance.
Foreign Direct Investment Law
Under the Foreign Direct Investment Law (Law No. 4875), Turkey maintains an open investment regime with national treatment for foreign investors. There are no general screening mechanisms for inbound acquisitions — a notable contrast to the increasingly restrictive foreign investment review frameworks in the EU and United States. Foreign entities may establish wholly-owned subsidiaries, acquire existing Turkish companies outright, or enter joint ventures without prior government approval in most sectors.
However, sector-specific regulations impose additional approval requirements in banking (BDDK approval for 10%+ acquisitions), insurance (SEDDK), energy (EPDK), telecommunications (BTK), and broadcasting (RTÜK, which caps foreign ownership at 50%). Defence sector transactions may trigger national security reviews under separate legislation.
Due Diligence Requirements for Foreign Acquirers in Turkey
Legal and Corporate Due Diligence
Comprehensive legal due diligence is the cornerstone of any successful M&A transaction in Turkey. Foreign acquirers must verify the target company’s corporate records at the Turkish Trade Registry (Ticaret Sicili), confirm share ownership structure, review board and general assembly resolutions, and examine all material contracts for change-of-control provisions. As we discussed in our guide to company formation in Turkey for foreign investors, the choice between limited liability company (LLC) and joint-stock company (JSC) structures has direct implications for share transfer mechanics and minority shareholder protections in M&A contexts.
Tax and Financial Due Diligence
Tax due diligence must examine the target’s corporate income tax compliance, VAT exposure, withholding tax obligations on cross-border payments, transfer pricing documentation, and any pending tax disputes or inspections. Turkey’s 25% corporate income tax rate, combined with the newly introduced minimum corporate tax regime effective January 2026, creates specific structuring considerations for acquisition vehicles. Foreign acquirers should evaluate whether the transaction should be structured as an asset purchase or share purchase based on available tax amortization benefits and potential successor liability exposure.
Employment and Labour Due Diligence
Turkish labour law imposes automatic transfer of employment relationships in the event of a business transfer under Article 6 of the Labour Law (Law No. 4857). All existing employment contracts, accrued severance entitlements, and collective bargaining agreements transfer to the acquirer by operation of law. Severance liability — calculated at approximately one month’s gross salary per year of service with no statutory cap on accrual — represents one of the most material hidden liabilities in Turkish M&A transactions.
Step-by-Step M&A Process in Turkey for Foreign Investors
1. Strategic Assessment and Target Identification
The process begins with strategic assessment of the Turkish market opportunity, sector-specific regulatory constraints, and identification of suitable acquisition targets. Foreign investors should engage Turkish legal counsel at this stage to assess preliminary regulatory feasibility and identify potential deal-breakers before incurring significant transaction costs.
2. Non-Disclosure Agreement and Preliminary Due Diligence
Execution of a bilateral NDA under Turkish law (governed by the Turkish Code of Obligations) precedes access to the target’s data room. Preliminary due diligence focuses on confirming the target’s legal standing, identifying material liabilities, and validating key commercial assumptions.
3. Letter of Intent or Term Sheet
A non-binding letter of intent or term sheet establishes the commercial parameters of the transaction: indicative valuation range, deal structure (share purchase vs. asset purchase), key conditions precedent, exclusivity period, and timeline. Under Turkish law, even non-binding LOIs may create good faith negotiation obligations under Article 29 of the Turkish Code of Obligations.
4. Comprehensive Due Diligence
Full-scope legal, tax, financial, employment, environmental, and IP due diligence is conducted. For transactions involving Turkish real estate assets, title deed (TAPU) verification and zoning compliance checks are essential. KVKK data protection compliance audits have become standard in technology and consumer-facing acquisitions.
5. Share Purchase Agreement Negotiation and Execution
The share purchase agreement (SPA) is the definitive transaction document, typically governed by Turkish law for domestic targets. Key provisions include representations and warranties, indemnification mechanics, purchase price adjustment mechanisms (locked-box or completion accounts), conditions precedent (including regulatory approvals), and post-closing covenants. For JSC share transfers, notarial endorsement of share certificates is required under the Turkish Commercial Code.
6. Competition Board Notification and Regulatory Approvals
If applicable thresholds are met, the parties must file a merger notification with the Turkish Competition Board before closing. The notification must include detailed market analysis, competitive overlap assessment, and supporting financial data. Phase I review takes approximately 30 days; Phase II investigation can extend to 6 months. Sector-specific approvals (BDDK, EPDK, BTK, etc.) run in parallel.
7. Closing, Registration, and Post-Acquisition Integration
Upon receipt of all required approvals, the transaction closes with share transfer, purchase price payment, and registration of the new ownership structure with the Turkish Trade Registry. Post-acquisition integration requires notification to tax authorities, social security institutions, and — where applicable — employees and counterparties under change-of-control clauses.
Costs, Thresholds, and Timelines for M&A in Turkey — 2026 Update
Competition Board filing fees for 2026 are set at 0.04% of the combined Turkish turnover of the transaction parties, with a minimum fee of approximately TRY 90,000 and a maximum cap. Notarial fees for share transfer endorsement in JSC transactions typically range from TRY 5,000 to TRY 50,000 depending on transaction value. Trade Registry registration fees are nominal but vary by commercial registry district.
The overall M&A timeline for a standard foreign investor acquisition in Turkey — from LOI to closing — typically ranges from 3 to 6 months. Transactions requiring Competition Board Phase II review or multiple sector-specific approvals may extend to 9-12 months. Turkish legal counsel fees for full-scope M&A representation are structured as fixed-fee or hourly arrangements depending on transaction complexity, with premium cross-border transactions typically commanding fees in the range of $50,000 to $250,000+ for comprehensive legal advisory.
Frequently Asked Questions: Mergers and Acquisitions in Turkey
Do foreign investors need Competition Board approval for M&A in Turkey?
Yes. Under the Turkish Competition Law (Law No. 4054) and the Communiqué No. 2010/4, mergers and acquisitions that exceed specified turnover thresholds require prior approval from the Turkish Competition Board (Rekabet Kurumu). As of February 2026, the revised thresholds require notification when cumulative Turkish turnover exceeds TRY 3 billion or individual Turkish turnover exceeds TRY 1 billion. Transactions completed without mandatory approval are deemed legally invalid.
What are the 2026 merger notification thresholds in Turkey?
Following the February 2026 amendment to Communiqué No. 2010/4, mandatory merger notification is triggered when (i) the combined Turkish turnover of transaction parties exceeds TRY 3 billion with at least two parties each exceeding TRY 1 billion, or (ii) in acquisitions, the Turkish turnover of the transferred assets or business exceeds TRY 1 billion and the worldwide turnover of at least one party exceeds TRY 3 billion. A lower threshold of TRY 250 million applies to technology undertakings established in Turkey.
How long does the M&A approval process take in Turkey?
The Turkish Competition Board operates a two-phase review system. Phase I review takes approximately 30 calendar days from complete notification. If the Board identifies potential competition concerns, it initiates a Phase II in-depth investigation, which can extend up to 6 months. Most straightforward foreign investor acquisitions are cleared in Phase I within 4-6 weeks.
Are there restricted sectors for foreign acquisitions in Turkey?
While Turkey generally applies equal treatment to foreign and domestic investors under the Foreign Direct Investment Law (Law No. 4875), certain strategic sectors impose additional regulatory requirements. Defence, energy, telecommunications, banking, insurance, and media sectors require sector-specific regulatory approvals beyond Competition Board clearance. The Banking Regulation and Supervision Agency (BDDK) must approve acquisitions of 10% or more in Turkish banks.
What due diligence is required for M&A transactions in Turkey?
Comprehensive M&A due diligence in Turkey should cover corporate records and share structure, real estate title deed (TAPU) verification, tax compliance history, employment obligations and severance liabilities, environmental permits, intellectual property registrations, pending litigation, regulatory licenses, and KVKK (data protection) compliance. Foreign investors should also verify that the target company has no undisclosed liabilities registered with the Turkish Trade Registry.
Can foreign companies acquire 100% of a Turkish company?
Yes. Under Turkey’s Foreign Direct Investment Law (Law No. 4875), foreign investors may acquire 100% ownership of Turkish companies in most sectors without requiring special permission. There are no general foreign ownership caps. However, sector-specific restrictions apply in broadcasting (maximum 50% foreign ownership), aviation, and certain energy concessions. The acquisition must still comply with Competition Board notification requirements if applicable thresholds are met.
