Cross-border mergers and acquisitions involving Turkish companies continue to be one of the most important channels for foreign investment into Türkiye. The Turkish Competition Authority’s 2025 M&A Overview Report states that foreign investors planned investments in Türkiye-based companies through 55 separate transactions in 2025, with a notified value of about TRY 277.5 billion, while the broader report also shows a very active control environment for acquisitions involving Turkish targets or Turkish market effects. At the same time, Türkiye’s official investment framework describes foreign investment legislation as simple, internationally aligned, and based on equal treatment for investors. That combination of market activity and legal openness is exactly why cross-border M&A transactions involving Turkish companies remain commercially attractive, but also legally technical.
The central legal point is that Türkiye does not operate a general economy-wide foreign investment approval regime for ordinary acquisitions merely because the buyer is foreign. The Investment Office states that the FDI Law is based on equal treatment, that international investors have the same rights and liabilities as local investors, and that the system is notification-based rather than approval-based. But that liberal baseline should not be misunderstood. A cross-border deal can still require merger clearance, sector-specific approvals, capital-markets compliance, document legalization, registry work, and post-closing foreign-investment reporting. In Turkish practice, the transaction is open in principle, yet layered in execution.
The basic legal framework for inbound and outbound Turkish M&A
The official Investment Office guidance states that the conditions for setting up a business and transferring shares are the same as those applied to local investors. It also confirms that foreign investors may establish any company form provided for under the Turkish Commercial Code and that joint stock companies (JSCs) and limited liability companies (LLCs) are the most common company types in Türkiye. For cross-border M&A, this matters because most foreign acquisitions of Turkish businesses are implemented through one of these vehicles, either by buying the shares of an existing Turkish target or by using a Turkish acquisition vehicle.
The same official source explains that company establishment and registration are handled through Trade Registry Directorates and that the Turkish system is organized as a kind of one-stop shop. This is commercially important in cross-border transactions because it shows that Turkish execution mechanics are registry-centered and document-driven. In other words, a cross-border deal involving a Turkish company is not completed only through an SPA signed abroad. It normally has to pass through Turkish corporate formality, local representation, and documentary usability requirements.
Cross-border structuring also depends on whether the transaction is a share deal, an asset deal, a merger, or a joint venture. The Competition Authority’s 2025 overview states that acquisitions may occur through shares, assets, or other means, and that a transaction becomes relevant under merger control when it results in a permanent change in control. The same report also notes that the establishment of a joint venture performing all the functions of an independent economic entity is treated as an M&A transaction. This matters because cross-border Turkish M&A is not defined only by nationality. It is defined by legal structure and control change.
Why document formalities matter so much in cross-border Turkish deals
One of the most practical issues in Turkish cross-border M&A is not substantive law, but the usability of foreign documents in Türkiye. The Investment Office states that documents issued and executed outside Türkiye generally must be notarized and apostilled, or alternatively ratified by the relevant Turkish consulate, and then officially translated and notarized by a Turkish notary before being used in Turkish procedures. This rule is highly important for board resolutions, powers of attorney, certificates of incumbency, constitutional documents, and foreign parent approvals. Many Turkish deals slow down not because the commercial terms are unsettled, but because the document chain was not prepared for Turkish use from the start.
This requirement has real transaction consequences. If the buyer is a foreign legal entity, counsel should expect Turkish closings to depend on apostilled authority documents and locally usable translations. If the deal involves a Turkish subsidiary acquisition, capital increase, joint venture formation, or branch-level reorganization, the foreign investor cannot safely assume that its home-country documents will be accepted in raw form. In Turkish M&A, documentary readiness is often as important as legal theory.
The same official guidance also explains that certain FDI-related forms, including the FDI Share Transfer Data Form, are submitted electronically through E-TUYS, and that those forms are no longer accepted in hard copy. This means a cross-border Turkish acquisition is not only a signing and closing event. It is also a reporting event inside Türkiye’s electronic foreign-investment system. For foreign investors, that makes post-closing compliance part of the deal architecture rather than a clerical afterthought.
Foreign investment is open, but sector limits still matter
Türkiye’s official investment materials say there are no restrictions on the nationality of shareholders or management-right holders except in certain sectors such as TV broadcasting, maritime, and civil aviation. This is one of the most important practical points in cross-border M&A involving Turkish companies. The general rule is openness; the exception is sector regulation. For that reason, the correct first question is rarely “Can a foreigner buy a Turkish company?” The better question is “Can a foreigner buy this Turkish company, operating in this sector, under this ownership and governance model?”
This distinction shapes due diligence and structuring. A foreign acquisition of an ordinary Turkish manufacturing, services, or software company may mainly raise company-law, competition-law, and document-formality issues. A foreign acquisition of a broadcaster, aviation business, maritime operator, or another specially regulated undertaking may require ownership analysis that goes far beyond the share transfer agreement. In Turkish practice, sector-specific rules do not eliminate cross-border deals, but they often change the permissible ownership structure or the approvals needed before closing.
Merger control is usually the most important approval issue
For a large number of cross-border M&A transactions involving Turkish companies, the most important regulatory issue is Competition Board authorization. The Competition Authority’s 2025 M&A Overview Report explains that certain transactions must be notified to the Competition Board and approved before they can become legally valid. The same report states that, for a transaction to fall within this regime, it must first create a permanent change in control. Share transfers that do not change control and acquisitions within the same economic entity are outside the notification requirement, but acquisitions of direct or indirect control over all or part of an undertaking are potentially inside it.
The current thresholds are especially important for cross-border deal teams. According to the Authority’s 2025 report, authorization is required where the total Turkish turnovers of the transaction parties exceed TRY 750 million and at least two transaction parties each have Turkish turnover above TRY 250 million, or, in acquisitions, where the target company, asset, or business has Turkish turnover above TRY 250 million and another transaction party has global turnover above TRY 3 billion. The same official report expressly states that mergers and acquisitions implemented abroad must still be notified in Türkiye if these thresholds are exceeded. That is the key reason foreign-to-foreign transactions can still require Turkish merger clearance.
This point is often underestimated in global transactions. A foreign buyer may acquire a foreign group in a deal signed and closed outside Türkiye, yet still need Turkish approval because the target has a Turkish business or because Turkish turnover thresholds are met. In that sense, Turkish merger control is not geographically narrow. It is effects-oriented and turnover-oriented. If the Turkish nexus is large enough, the acquisition cannot be analyzed only through the laws of the buyer’s or seller’s home jurisdiction.
The current Turkish regime is also highly active. The Competition Authority’s 2025 report states that it examined 416 merger and acquisition transactions in 2025, the highest number in the last thirteen years, and that all notified transactions received final decisions after an average of 10 days following the final date of notification. That combination of volume and speed is important for cross-border M&A. It shows that Turkish review is not exceptional or dormant; it is a live, high-throughput system that sophisticated deal teams should build into their timetable from the start.
Technology deals require additional caution
Cross-border acquisitions involving Turkish technology businesses or Turkish users deserve special attention. The Competition Authority’s 2025 report notes that the usual TRY 250 million threshold is disregarded in certain transactions involving technology companies operating or conducting R&D in the Turkish geographic market or providing services to users in Türkiye. This means that software, gaming, fintech, biotech, platform, and health-tech transactions with a Turkish nexus may require a more careful filing analysis than a conventional turnover-only review would suggest.
For foreign investors, this is particularly significant because many Turkish technology targets may still be at a growth stage where local revenue does not yet look large in absolute terms. Yet if the business has Turkish users, Turkish R&D, or falls inside the official technology-company logic, Turkish merger-control exposure can arise earlier than expected. In cross-border M&A, this makes “niche Turkish digital business” a potentially more regulated acquisition than its headline revenue would imply.
Public company deals add a separate capital-markets layer
If the Turkish target is a publicly held company, the transaction enters the capital-markets regime as well. Official CMB search results and legislation pages identify the Communiqué on Takeover Bids (II-26.1) and the broader capital-markets framework as the main source for voluntary and mandatory takeover bids, while the Capital Markets Law itself regulates takeover-bid obligations tied to control. In practical terms, this means a cross-border acquisition of a listed or publicly held Turkish company can trigger not only merger-control analysis, but also tender-offer rules, equal-treatment principles, and public disclosure obligations.
This public-company layer matters because a foreign bidder cannot treat a Turkish listed company acquisition as if it were a private bilateral block trade only. Once management control or the relevant capital-markets thresholds are reached, the takeover-bid regime may require the acquirer to engage with the broader shareholder base as well. Public Turkish M&A is therefore structurally different from private-company M&A, even where the foreign investor’s commercial objective is simply to acquire control.
Joint ventures are often used in cross-border Turkish M&A
Cross-border M&A involving Turkish companies is not limited to straight acquisitions. Many foreign investors enter the market through joint ventures with Turkish partners. The Investment Office states that a joint venture is generally considered an ordinary partnership under Turkish law, but that parties usually choose to establish a commercial company, most often a joint stock company, and that it is common practice to conclude a shareholders’ agreement governing the relationship between the joint venture parties. The same guidance also states that there is no specific joint venture legislation in Türkiye, so the arrangement is governed by the company type and the contractual structure chosen.
This is important in cross-border practice because many foreign investors prefer staged entry rather than full acquisition. A Turkish joint venture can be commercially useful for market access, licensing, sector know-how, or gradual capital deployment. Legally, however, it requires careful design around governance, share transfer, reserved matters, deadlock, and exit rights precisely because there is no single JV code that fills those gaps automatically. In a cross-border setting, the shareholders’ agreement usually becomes the core operational constitution of the relationship.
Cross-border JVs can also raise merger-control issues. The Competition Authority’s 2025 report states that a joint venture permanently performing all functions of an independent economic entity is treated as an M&A transaction. So even where the foreign investor is not buying 100% of a Turkish company, Turkish competition law can still become relevant if the JV is functionally autonomous and the turnover thresholds are met.
Deal execution depends on company type and local formalities
The underlying Turkish company type can materially affect the difficulty of execution. The Ministry of Trade guide explains that, in a joint stock company, approval of the general assembly is generally not required for share transfers and shareholders may freely transfer shares, whereas in a limited company, transfer is subject to a written and notarized agreement, general-assembly approval unless otherwise provided, and registration or announcement steps. For cross-border acquisitions, this difference is highly practical. The same foreign investor may face a relatively clean share transfer in one Turkish target and a much more approval-intensive process in another simply because the company form differs.
This is why cross-border Turkish M&A due diligence should always confirm the legal form early. A buyer that assumes it is purchasing a Turkish company in a simple corporate form may discover later that the transfer cannot be completed without internal approvals, notarization, or recordal steps that were not built into the timetable. In inbound deals, local formalities are not friction at the edge of the deal. They are part of the core execution mechanics.
E-TUYS, registry practice, and closing readiness
Cross-border closing readiness in Türkiye usually depends on three parallel tracks. The first is the corporate authority track, meaning the seller’s and buyer’s approvals and signing power. The second is the document legalization track, meaning apostille, consular verification, translation, and notarization. The third is the reporting and registry track, meaning trade-registry usability and, where foreign investors are involved, E-TUYS filings such as the FDI share transfer reporting. The Investment Office’s materials set out each of these elements clearly enough that no inbound deal should reach closing without addressing them expressly.
This matters especially when the foreign investor assumes that signing abroad is enough. In Turkish practice, a deal can be economically settled and still not be procedurally ready. The need for apostilled documents, Turkish notarization, Turkish-resident representation in some procedures, and post-closing electronic FDI reporting means closing is often a more technical process than non-Turkish buyers first expect. A well-run Turkish M&A process therefore aligns legal drafting with document production from the beginning.
How current market data affects strategy
The Competition Authority’s 2025 report provides a useful current picture of how cross-border Turkish M&A is actually happening. It records 68 transactions involving at least one Turkish and one foreign party among the Türkiye-based transactions finalized in 2025, and separately notes the significant value of foreign-investor acquisitions of Türkiye-based targets. That matters because it shows cross-border M&A involving Turkish companies is not a narrow niche. It is a routine and substantial part of the Turkish transaction environment.
This market activity has two practical implications. First, foreign investors should not assume that Turkish approvals or formalities are unusual or untested. They are part of an active and regularly used system. Second, competitive deal processes involving Turkish targets may move quickly, which means buyers need Turkish legal workstreams—competition, foreign-investment reporting, document legalization, and sector review—to start early rather than waiting until the SPA is nearly finalized.
Key legal risks that often shape cross-border Turkish deals
The most common legal mistakes in cross-border Turkish M&A are usually not dramatic violations; they are category errors. One category error is assuming that a foreign acquisition does not need Turkish merger clearance because the signing is offshore. Another is assuming that foreign documents can be used in Türkiye without apostille and notarized translation. A third is treating a Turkish listed-company acquisition like a private block trade and discovering tender-offer consequences too late. A fourth is ignoring sector-specific restrictions because the FDI regime is generally liberal. Each of these mistakes comes from misunderstanding how Türkiye combines an open investment policy with formal legal execution rules.
A related risk is timeline mismatch. Turkish law may allow the acquisition commercially, but the closing date in the SPA can still be unrealistic if the deal team has not built in merger-clearance timing, legalization of foreign documents, internal approvals for limited-company transfers, and E-TUYS or registry follow-through. In cross-border M&A involving Turkish companies, timetable discipline is a legal issue, not only a project-management issue.
Conclusion
Cross-border M&A transactions involving Turkish companies operate inside a legal framework that is open in principle but layered in execution. Türkiye’s official investment regime is based on equal treatment and a notification-based FDI model, and foreign investors may acquire Turkish companies under the same general company-law framework that applies to local investors. But that openness exists alongside real legal filters: Turkish merger control can apply to foreign-to-foreign deals, technology transactions receive special scrutiny, public company acquisitions can trigger takeover-bid rules, certain sectors remain specifically regulated, and foreign-executed documents must usually be apostilled, translated, and notarized for Turkish use.
The practical takeaway is simple. A successful cross-border Turkish acquisition is rarely the result of one good SPA alone. It is the result of matching structure, approvals, document formalities, and post-closing reporting to the legal reality of the target and the transaction. Buyers who treat Turkish workstreams as central from the start usually close more smoothly. Buyers who treat them as local clean-up items often discover that the hardest part of the deal was not the negotiation, but the Turkish execution logic sitting behind it.
