When a buyer evaluates an acquisition in Turkey, the legal question is rarely limited to price, valuation, or the transfer mechanics of the shares. The more decisive question is often whether the transaction can legally close without one or more regulatory approvals. In Turkish deal practice, an acquisition may require review not only under competition law, but also under banking, insurance, capital markets, media, foreign-investment, and real-estate rules, depending on the target’s business and asset profile. Turkey’s official investment guidance states that foreign investors are generally treated on an equal footing with local investors and that the conditions for setting up a business and transferring shares are the same as those applied to local investors. At the same time, the same official guidance makes clear that sector-specific exceptions and post-closing reporting obligations still exist.
That combination of openness and regulation explains why acquisitions in Turkey should be analyzed through two different lenses at once. First, there is the general acquisition framework, under which share transfers are in principle possible and foreign investment is broadly permitted. Second, there is the approval framework, under which certain transactions must obtain consent from public authorities before they become legally valid or before the acquirer may safely exercise control. In practice, the most important approval regimes usually involve the Turkish Competition Board, the Banking Regulation and Supervision Agency, the Insurance and Private Pension Regulation and Supervision Authority, and the Capital Markets Board for publicly held companies, with additional layers in sectors such as broadcasting and in certain real-estate situations involving foreign-controlled Turkish companies.
This article explains the main regulatory approvals required for acquisitions in Turkey and, just as importantly, when a transaction may not need a pre-closing approval but still requires regulatory filings, reporting, or compliance steps. That distinction is critical because many foreign investors mistakenly assume that Turkey either operates a broad approval-based foreign investment screening regime or no meaningful approval regime at all. The correct answer is more nuanced. Turkey’s FDI framework is fundamentally notification-based rather than approval-based, but acquisition approvals still arise where competition law, sector law, public-company rules, or asset-specific regimes require them.
The starting point: foreign investment is generally open, but not unregulated
Turkey’s official investment materials describe the country’s foreign investment legislation as simple, internationally aligned, and based on equal treatment for investors. The Investment Office also states that the Foreign Direct Investment Law aims to encourage FDI, protect investor rights, and establish a notification-based rather than an approval-based system. That is the starting point for acquisition analysis in Turkey. A foreign investor does not usually need a universal, economy-wide foreign-investment screening clearance merely because it is foreign. Instead, the investor typically needs to determine whether the target falls into a regulated sector, whether merger control is triggered, and whether post-closing reporting and formalities must be completed.
The same official guidance is also clear that international investors may establish any company form recognized by the Turkish Commercial Code, and that the most common vehicles are joint stock companies and limited liability companies. It further explains that the Trade Registry system functions as a one-stop shop for company formation and that foreign-issued documents to be used in Turkey generally must be notarized and apostilled, or alternatively ratified by the Turkish consulate, and then translated and notarized in Turkey. So even when no special acquisition approval is required, a foreign-led deal can still depend on registry usability, signatory authority, and documentary formalities.
An equally important practical point is the E-TUYS system. The Investment Office states that the Activity Information Form for FDI, the FDI Capital Data Form, and the FDI Share Transfer Data Form are now submitted electronically through E-TUYS and are no longer received in printed form. This does not usually make E-TUYS a pre-closing approval condition in the same way as merger clearance, but it does make it a core compliance step in many foreign-led acquisitions. In other words, Turkey does not generally require pre-approval simply because foreign capital is involved, but it does require the transaction to be properly reported and documented after closing.
Competition Board approval is the most common acquisition approval in Turkey
For a wide range of transactions, the most important regulatory approval required for an acquisition in Turkey is Competition Board clearance. Communiqué No. 2010/4 states that its purpose is to identify the mergers and acquisitions that require notification to and authorization by the Competition Board in order to gain legal validity. The same communiqué explains that it applies to transactions falling within Article 7 of the Competition Act and that notifiable mergers and acquisitions must receive Board authorization before becoming legally valid.
The Turkish Competition Authority’s 2025 M&A Overview Report explains the core trigger in practical terms. A transaction first has to create a permanent change in control. The report further states that acquisitions can occur through shares, assets, or other means and that a full-function joint venture can also qualify as an M&A transaction. It also states that share transfers that do not change control and acquisitions within the same economic entity are not subject to notification. That means Competition Board approval is not required for every share sale, but it becomes mandatory where the transaction changes control and crosses the relevant thresholds.
The same official report sets out the current thresholds. Competition Board authorization is required where the total Turkish turnovers of the transaction parties exceed TRY 750 million and the Turkish turnovers of at least two parties each exceed TRY 250 million. Authorization is also required where, in an acquisition, the target company, asset, or business has Turkish turnover exceeding TRY 250 million and another transaction party has global turnover exceeding TRY 3 billion. The report also confirms that transactions implemented abroad must still be notified in Turkey if the thresholds are exceeded, which is why foreign-to-foreign transactions involving a Turkish nexus frequently require Turkish merger clearance.
Competition approval has become even more important because of Turkey’s special treatment of technology undertakings. The Competition Authority’s current framework, reflected in the communiqué and in recent official reporting, treats certain acquisitions involving digital, software, gaming, fintech, biotech, pharmacology, agricultural chemicals, and health technology businesses differently from ordinary turnover-only cases. In practice, this means some technology transactions with a Turkish nexus need to be screened more carefully for filing risk, even if the Turkish turnover profile looks modest at first glance.
Timing also matters. The Competition Authority reported that it examined 416 transactions in 2025 and that all notified merger and acquisition transactions received final decisions after an average of 10 days following the final date of notification. That relatively short average does not make filing optional; it simply means that a well-prepared filing can often be integrated into the timetable efficiently. The critical point remains that, where the transaction is notifiable, Board approval is a true pre-closing regulatory condition.
Banking acquisitions require BRSA approval at specified thresholds
Acquisitions involving banks are subject to one of the clearest approval regimes in Turkish law. Under Article 18 of the Banking Law, any acquisition of shares that results in one person directly or indirectly acquiring 10 percent or more of a bank’s capital, or crossing the thresholds of 10 percent, 20 percent, 33 percent, or 50 percent, requires the permission of the Board. The same article provides that assignments causing a shareholder’s stake to fall below those thresholds also require permission. In addition, transfers of preferential shares carrying board or audit committee appointment rights, or the issuance of new privileged shares, require authorization regardless of those thresholds.
The Banking Law goes further than a simple approval obligation. It states that unauthorized transfers are not to be recorded in the share ledger and that any such entries are null and void. It also provides that the same principles apply to the acquisition of voting rights and the establishment of usufruct rights over shares. This means that, in the banking sector, an acquisition can fail not only because approval was not obtained, but because the legal effects of the transfer itself are blocked under sector legislation.
Article 19 of the same law adds another layer for structural transactions. It states that Board permission is required for a bank operating in Turkey to merge with one or more other banks or financial institutions, to transfer all its assets and liabilities and other rights and obligations to another bank, to take over all the assets and liabilities and rights and obligations of another bank, to disintegrate, or to change shares. So in banking M&A, both acquisitions of shareholding thresholds and broader reorganization transactions fall squarely within the approval regime.
The practical implication is straightforward. An acquisition of a regulated bank in Turkey cannot be analyzed only as a corporate or competition-law exercise. BRSA approval is often a primary closing condition, and without it the transfer may not produce the legal effect the parties expect. For investors, this makes banking one of the most approval-intensive acquisition sectors in the Turkish market.
Insurance acquisitions are also approval-driven
Insurance-sector acquisitions in Turkey are similarly regulatory in nature. The Insurance and Private Pension Regulation and Supervision Authority’s official activity reporting states that establishment, licensing, merger, share transfer, portfolio transfer, and title change transactions of insurance, reinsurance, and pension companies are evaluated within the framework of the Insurance Law, the private pension legislation, and the relevant implementing regulations. That official description alone shows that acquisitions in the insurance sector are not treated as ordinary private corporate transfers.
The same official reporting also confirms that share-transfer requests are not theoretical. The Authority states in its 2024 annual report that approval was granted for the share transfers of ten companies, and its earlier reports likewise note that share-transfer applications are reviewed and approved within the sector’s supervisory framework. These reports demonstrate the regulatory practice clearly: when an acquisition concerns an insurance or pension undertaking, the deal team should expect regulatory review by the specialized authority, not merely company-law execution.
In practical terms, insurance approvals matter for many of the same reasons as bank approvals. Regulators assess not only the formal transfer itself, but also the financial strength and reputation of the shareholders, the organizational structure, and the institution’s ability to continue operating on a sound basis. The official 2020 activity report describes this broader supervisory assessment in some detail, including review of shareholder strength, organizational structure, capital adequacy, and operational readiness. So the relevant approval in insurance M&A is functionally connected to prudential oversight, not just ownership change.
Public company acquisitions trigger capital-markets approvals and takeover rules
When the target is a publicly held company, the acquisition process also enters the capital-markets regime. Turkey’s official capital-markets legislation page lists II-26.1 Communiqué on Takeover Bids, II-23.2 Communiqué on Merger and Demerger, and II-27.2 Communiqué of Squeeze-out and Sell-out Rights among the relevant rules. The Capital Markets Law itself also provides, in Article 25, that the procedures and principles related to voluntary takeover bids and mandatory takeover bids arising from management control in publicly held corporations are determined by the Board.
The official search result for the takeover-bids communiqué states that it sets out the principles relating to voluntary and mandatory takeover bids in publicly held corporations. The squeeze-out and sell-out rights communiqué is also an important part of the framework, and the public-company materials confirm that “management control” concepts are central in this area. For acquisition planning, that means a bidder for a listed Turkish company may face not only ordinary share-transfer mechanics, but also mandatory tender-offer consequences, disclosure obligations, and minority shareholder protections.
This does not always operate as a single approval in the same way as a banking consent, but it is still a regulatory regime that can materially affect the ability to close or the conditions on which control may be acquired. Public M&A in Turkey is therefore structurally different from private-company M&A, and acquisition documents need to incorporate the capital-markets timetable from the start.
Broadcasting acquisitions must respect ownership limits and RTÜK-related requirements
Media and broadcasting transactions in Turkey require special care because sector law imposes ownership limits and licensing rules. The official English text of the Audio-visual Media Law states that the total direct foreign capital share in a media service provider may not exceed 50 percent of the paid-in capital and that a foreign real or legal person may directly become a partner of a maximum of two media service providers. The same article also requires, where foreign persons become indirect partners through intermediate companies, that the chair, deputy chair, and majority of the board as well as the general manager be Turkish citizens, and that the majority of votes in the general assembly belong to Turkish citizens or Turkish legal persons.
The same law also shows that RTÜK’s role is not limited to content supervision. It provides for broadcasting licenses and transmission authorizations and states that, in public offerings of media service providers, the consent of the Supreme Council must be obtained before registration with the Capital Markets Board. While that specific rule is framed in capital-markets terms, it illustrates a broader point for acquisitions: when the target holds broadcasting licenses or sits inside a licensed media structure, the acquisition must be screened not only for general company-law validity but also for compliance with sector ownership and authorization rules.
For buyers, this means that a media acquisition can be blocked not simply because an authority dislikes the transaction commercially, but because the post-closing ownership composition would violate the law’s foreign-shareholding limits or its governance requirements for indirectly foreign-owned broadcasters. In that sense, broadcasting is another example of a sector where equal-treatment principles are qualified by specific legal limits.
Foreign-owned Turkish companies may need permission for certain real-estate acquisitions
Real-estate rules do not usually determine whether a company acquisition may happen at all, but they can create an additional approval layer after a foreign investor acquires control of a Turkish company that holds or plans to acquire real estate. The Investment Office states that Turkish companies with foreign capital are treated as foreign-owned companies for real-estate purposes where foreign investors hold 50 percent or more of the shares or are entitled to appoint and dismiss the majority of the board of directors. Such companies may acquire property and limited rights in rem for the activities set out in their articles of association, but they must first apply to the governor’s office where the property is located.
The same official guidance adds that if the relevant property is located in a prohibited military zone or military security zone, permission of the General Staff is required, while property in a private security zone requires permission from the governor’s office. It also clarifies that certain transactions do not require governor’s-office permission, including the creation of a mortgage, acquisitions in organized industrial zones and certain other designated zones, and transfers arising out of mergers and demergers. This means that, in acquisitions involving real-estate-heavy targets, the regulatory analysis does not always stop at the share transfer itself. Control changes can bring the target into the foreign-owned company regime for land-law purposes.
This is not a universal acquisition approval in the same sense as merger control, but it is still highly relevant in practice. A buyer that acquires a Turkish company with major real-estate assets may discover that future asset movements, registrations, or expansion plans depend on permissions that a purely domestic company would not need in the same way. That is why real estate should be part of the regulatory approval map in many inbound Turkish transactions.
Some transactions require filings rather than approvals
A recurring source of confusion in Turkish M&A is the difference between a filing and an approval. Competition Board clearance, banking permissions, and some sector consents are true approvals. By contrast, E-TUYS reporting is generally a filing obligation rather than a prior authorization. The Investment Office makes this distinction clear by describing the FDI system as notification-based and by explaining that the relevant FDI forms, including the FDI Share Transfer Data Form, are submitted electronically through E-TUYS.
This difference matters because parties often over-lawyer the wrong issue. A transaction may not need a broad foreign-investment pre-approval simply because the acquirer is non-Turkish, but it may still require post-closing filings, registry formalities, and local-document legalization. Conversely, a transaction may look routine from an FDI perspective while actually requiring a hard regulatory approval because the target is a bank, insurer, broadcaster, or listed company, or because the merger-control thresholds are exceeded. The safest approach is therefore to separate the regulatory matrix into “must be approved before closing” and “must be filed or completed as part of closing or immediately after.”
Regulatory approvals shape the acquisition agreement itself
Because these approvals can be decisive, Turkish acquisition agreements are usually drafted around them. Competition clearance often appears as a condition precedent. BRSA or insurance-authority permission may be written as a mandatory regulatory condition with a long-stop date. Public-company deals may include detailed tender-offer compliance provisions. Cross-border deals routinely contain covenants on apostille, notarization, Turkish translations, and delivery of authority documents that the trade registry or regulators will accept. The official Turkish investment guidance on document legalization and trade-registry processes explains why these mechanics are so central.
In practice, the correct regulatory condition language depends on the sector. A competition filing usually raises questions about remedies, cooperation, and risk allocation if the authority requests more information. A banking or insurance approval often raises questions about who bears the risk of rejection and whether the parties must propose an alternative structure. A media or listed-company acquisition requires the agreement to accommodate ownership caps, tender-offer requirements, or sector licensing logic. The underlying business may be the same, but the approval package can change the transaction design completely.
A practical approval map for acquisitions in Turkey
The most useful way to think about Turkish acquisition approvals is as a layered sequence. The first layer asks whether the deal changes control and triggers Competition Board authorization. The second asks whether the target operates in a prudentially regulated sector such as banking or insurance, where a specialized regulator’s consent may be required for share acquisitions, mergers, or reorganizations. The third asks whether the target is a publicly held company, in which case the Capital Markets Board regime on takeover bids and related rules comes into play. The fourth asks whether the target is a media service provider, where RTÜK-related ownership and authorization rules matter. The fifth asks whether the target, after the acquisition, becomes a foreign-owned Turkish company holding real estate in a way that triggers governor’s-office permission for asset-side actions. Alongside all of that sits the E-TUYS and registry formalities layer.
Not every acquisition will involve all of these layers. Many ordinary private-company deals only need company-law execution and, where thresholds are met, Competition Board clearance. But for regulated targets, approvals can become the central issue in the transaction. That is why acquisition planning in Turkey should always begin with a regulatory perimeter analysis, not only with financial modeling or headline valuation.
Conclusion
The phrase regulatory approvals required for acquisitions in Turkey does not refer to one single approval. It refers to a framework in which different authorities may become relevant depending on the nature of the deal. Turkey’s baseline FDI policy is open and notification-based, with equal treatment for foreign and domestic investors, but that baseline is overlaid by hard approval regimes in merger control, banking, insurance, public-company acquisitions, and certain sector-specific ownership structures. Real-estate permissions and post-closing E-TUYS filings add further compliance layers in many inbound transactions.
For investors, sellers, and counsel, the practical takeaway is simple. An acquisition in Turkey should never be documented as though the only task is to transfer the shares. The correct question is which approvals, consents, filings, and formalities stand between signing and legally effective closing. In some deals, that answer is “none beyond ordinary corporate execution.” In others, it includes Competition Board clearance, BRSA permission, insurance authority approval, takeover-bid compliance, RTÜK-related ownership analysis, and real-estate permissions for a foreign-controlled company. The transactions that close smoothly are usually the ones where that map is prepared at the start rather than discovered midway through the closing process.
