INTRODUCTION Legal regulations concerning the promotion of medicines and medicinal products for human use in Türkiye aim to strike a delicate balance between protecting public health and ensuring the sector's right to pursue legitimate commercial activities. Accordingly, the means by which promotion may be conducted, the target audience, and the limits within which it must remain have been specified in detail by law and secondary legislation; in particular, the distinction between scientific communication and commercial promotion has been established through a careful normative architecture. The normative framework, which began with the Pharmaceutical and Medical Preparations Act No. 1262 of 1928, is now essentially shaped by the Regulation on Promotion Activities for Medicinal products for human use (the “Regulation”). The legislation generally prohibits advertising to the public, while stipulating that advertising activities directed at healthcare professionals must be conducted in accordance with specific rules and principles of transparency and proportionality. The purpose of this article is to examine the legal regime governing the promotion of medicines and medicinal products in Türkiye, including its normative framework, scope of application, and sanction mechanisms, and to evaluate key issues such as the ban on promotion to the general public, the limits of promotion to healthcare professionals, scientific meetings, and the legal nature of digital promotional activities from a holistic perspective. The article also aims to analyze the structural problems encountered in regulations concerning promotional activities, uncertainties in implementation, and new legal needs arising from technological developments, and to provide assessments regarding the effectiveness and improvement of legislation. I. THE NORMATIVE DEFINITION AND SCOPE OF PROMOTIONAL ACTIVITIES A. Legal Boundaries of the Concept of Promotion Promotion refers to all information-sharing activities carried out with healthcare professionals regarding the medical and scientific characteristics of products, including the activities and visits of product promotion representatives, advertisements in medical and professional publications, announcements made through communication tools, scientific meetings, product promotion meetings, and similar activities. This definition shows that the concept of promotion is considered in a broad spectrum. Legislation does not limit promotion to direct advertising activities only, but also includes information provision, education, and scientific communication activities. This approach reflects a protective regulatory understanding that takes into account the multidimensional nature of drug promotion and its potential areas of impact. B. Limitation of the Promotion Audience Promotion covers promotional activities for products aimed at doctors, dentists and pharmacists, and the promotion of medicinal products for human use to any other professional group is not permitted. The restriction of the promotion recipient is based on the assumption that decisions regarding the use of medicines require medical knowledge and expertise. C. Classification of Promotion Methods Promotion is carried out using promotional materials, by organizing or supporting scientific meetings and product promotion meetings, and through visits by product promotion representatives. The legislation regulates promotion methods in three main categories: (i) promotional materials, (ii) meetings, and (iii) individual visits. This classification reflects the understanding that different promotion methods carry different risks and therefore require different regulatory approaches.   II. LEGAL BASIS AND SCOPE OF THE PUBLIC PROMOTION PROHIBITION A. General Prohibition Principle and Legal Justifications Products cannot be promoted directly or indirectly to the public through any media or communication channels, including the internet, and this promotion ban also covers patients, meaning that promotion cannot be directed at patients or their relatives. The prohibition on advertising to the public is one of the cornerstones of the Turkish pharmaceutical law system. This prohibition aims to prevent individuals from making decisions regarding the use of medicines under the influence of medical information asymmetry and advertising. The prohibition is based on public interest grounds such as the protection of public health and the rational use of medicines. B. Exceptions and Limits to the Ban Information about medicines may be provided, but this content must not be promotional in nature. In addition, information regarding the approved instructions for use and indications of products by the Turkish Medicines and Medical Devices Agency may be published on the websites of pharmaceutical companies. These exceptions aim to strike a balance between the right to information and the protection of public health by preventing the strict application of the ban on advertising to the public. However, the scope of the exceptions should be interpreted narrowly and should not be broadened in a way that would undermine the purpose of the ban. C. Distinction Between Providing Information and Advertising Licence or authorization holders may create their own websites and social media pages to provide information about diseases, but this information must not be intended, either explicitly or implicitly, to promote or direct people towards a particular medicine. There is no objection to sharing general information such as information about the disease and methods of protection against diseases, and even information about treatment methods may be provided, but information such as “this medicine is good for this disease” cannot be provided. The distinction between providing information and advertising is one of the most sensitive and open to interpretation areas of legislation. This distinction creates the obligation to determine the fine line between objective information and commercial messages. The legislation requires an assessment based on the nature of the content (scientific/commercial), its purpose (educational/sales) and its effect (informative/promotional).   III. REGULATORY FRAMEWORK FOR ADVERTISING TARGETED AT HEALTH PROFESSIONALS A. Legal Nature of the Prohibition on In-Kind and Monetary Benefits When conducting promotional activities, no in-kind or monetary benefits may be provided to healthcare professionals, nor may they be offered, and the relevant healthcare professionals may not accept or request any incentives during the promotional activity conducted for them. The prohibition of in-kind and monetary benefits is a fundamental regulatory tool aimed at preserving independence and objectivity in the relationships between the pharmaceutical industry and healthcare professionals. This prohibition serves the purpose of preventing conflicts of interest, ensuring that medical decisions are made on a scientific basis, and protecting the professional independence of healthcare professionals. The fact that the prohibition includes the phrase "may not even be offered" indicates that it prohibits not only the actual provision of benefits but also any initiative that could potentially create a conflict of interest. This broad scope reflects a preventive approach. B. Regulation of Promotional Materials Promotional materials cannot be other than those defined in the legislation and must be directed solely at healthcare professionals; they refer to any material distributed at meetings or visits directed at healthcare professionals, and the monetary value of these materials must not exceed 2.5% of the current gross monthly minimum wage. These materials may include symbolic visit gifts that can be used during the practice of the profession, visual or audio materials such as brochures, slides, or films containing information about the product, any publications or electronic access to them that can be used as a source of information or reference about the product, free samples, demo devices, and materials for patient education. The regulation of promotional materials imposes restrictions in terms of both content and value. Linking the monetary value limit to the minimum wage reflects a dynamic regulatory approach that provides automatic updates in inflationary environments. These materials should not be positioned or displayed in a manner visible to the public. This regulation aims to prevent promotional materials from becoming an indirect means of promotion to the public and creates a complementary protection mechanism that enhances the effectiveness of the ban on public promotion. C. Prohibition on the Use of Healthcare Professionals in Advertising The Regulation also prohibits healthcare professionals from appearing as actors in product promotions without special permission from the Ministry of Health. This prohibition aims to prevent the credibility and authority of healthcare professionals in the eyes of society from being exploited for commercial purposes. The prohibition aims both to protect the professional reputation of healthcare professionals and to prevent the public from being misled. IV. LEGAL ASPECTS OF SCIENTIFIC MEETINGS AND SUPPORT MECHANISMS A. Legal Nature and Scope of Scientific Meetings Scientific meetings are congresses, symposiums, workshops and similar meetings organized by license and permit holders for the purpose of providing information on scientific topics; these meetings may also be organized electronically, but in this case the meeting cannot be open to the public, participants must have their own username and password, and can only access the meeting on the days of the meeting. Scientific meetings constitute one of the legitimate areas of interaction between the pharmaceutical industry and healthcare professionals. These meetings serve legitimate purposes such as sharing scientific knowledge, communicating medical developments, and supporting professional education. However, these legitimate purposes may be intertwined with commercial interests and may create a risk of conflict of interest. B. Participant Support Mechanism and Restrictions A healthcare professional may receive support for scientific and electronic scientific meetings a total of four times within a calendar year; for a maximum of two of these four instances, support may be provided by the same licence/permit holder; the meeting must be on scientific topics related to the healthcare professional's area of expertise/duty. The regulation of the participant support mechanism reflects the effort to strike a balance between scientific training needs and the risk of dependency. Limiting the number of annual supports and restricting the number of supports that can be received from the same company aims to prevent healthcare professionals from becoming dependent on specific companies. C. Types of Support and Legal Limits The Regulation details the types of support that can be provided for scientific meetings. In this context, general sponsorship of a scientific meeting is provided solely to the organizer for the purpose of holding the meeting; this support cannot be used to cover participants' registration, accommodation or travel expenses. In contrast, participant and speaker support is a separate type of support that refers to the license/authorization holder covering the registration, accommodation, travel and speaker fees on behalf of individuals attending, presenting or submitting papers at the meeting. Satellite symposiums are sessions held during scientific meetings for product promotion, and the support provided for these sessions, as with general sponsorship, cannot be used to cover participants' individual expenses. Furthermore, stand participation support is provided in the form of the licence/permit holder renting a stand in the organisation area for the purpose of product or company promotion and covering expenses related to refreshments and similar items at the stand. The fact that the types of support are differentiated in this way and different rules are stipulated for each one demonstrates that the Regulation adopts a detailed, restrictive and comprehensive regulatory technique. The fact that all this support is directed not to individuals but to the organisation hosting the meeting is a fundamental principle aimed at preventing personal gain and increasing transparency. D. Principle of Reasonableness and Proportionality The support provided must be reasonable and not excessive, and hospitality that overshadows the meeting itself must also be avoided. The principle of reasonableness and proportionality aims to ensure that scientific meetings do not deviate from their primary purpose and do not turn into luxury holidays or entertainment events. E. Notification and Oversight Mechanisms Licence/permit holders shall apply to the Turkish Medicines and Medical Devices Agency for scientific meetings they will organize or support; at least fifteen working days prior to each domestic meeting, the content of the meeting, the list of potential participants, the items of expenditure to be incurred, and the activities must be reported to the Agency; Notifications are responded to by the Agency within ten working days; if no response is received, the application is deemed approved; after the sponsored meeting has taken place, the license/authorization holder must notify the Agency in detail of the list of participants, expense items, and activities carried out within a maximum of thirty days. Notification obligations are important regulatory tools aimed at increasing transparency and facilitating oversight. The tacit approval mechanism (approval deemed granted if no response is provided) aims to streamline administrative processes and reduce bureaucracy. Health inspectors appointed by the Turkish Medicines and Medical Devices Agency may attend these meetings with or without prior notice for inspection purposes. This regulation provides the opportunity for surprise inspections, which are necessary for effective oversight. V. PRODUCT PROMOTION MEETINGS AND THEIR DIFFERENCES FROM SCIENTIFIC MEETINGS A. Legal Nature of Product Promotion Meetings Product promotion meetings are meetings organized by the license or permit holder to promote their product; the purpose is to convey existing medical information about the products and to present new information about them; product promotion meetings can only be organized by the license/permit holders of medicinal products for human use. Unlike scientific meetings, product promotion meetings are directly product-focused. These meetings occupy a middle ground between scientific knowledge sharing and commercial promotion. B. Comparative Analysis of Support Restrictions In product promotion meetings organized by license/authorization holders, the travel and accommodation expenses of participants, excluding speakers, cannot be covered by the license/authorization holders. This regulation demonstrates that product promotion meetings have more limited support opportunities than scientific meetings. The distinction reflects a differentiated regulatory approach based on the nature of the meeting (scientific/commercial). While scientific meetings may be held for students studying at faculties or colleges that train healthcare professionals, product promotion meetings may not be organized. This prohibition aims to prevent students from being exposed to commercial promotion and to protect the independence of the educational process. VI. LEGAL ISSUES RELATED TO PROMOTION IN THE DIGITAL ENVIRONMENT A. General Principles of Promotion in the Digital Environment With the advancement of technology, globalization, and the increasing importance of digital communication, pharmaceutical companies have begun to conduct their promotion and marketing activities not only physically but also in the digital environment; corporate digital marketing has become an increasingly important issue, particularly in a competitive environment, and one of the main reasons for this is its advantages, such as providing fast and easy access to a large number of people at low cost. The rules applicable to promotion in the physical environment are equally applicable to promotion in the digital environment, with no flexibility whatsoever. Just as in the physical environment, products cannot be promoted directly or indirectly to the public in the electronic environment. The legislation clearly states that the change in environment does not change the rules and does not treat the digital environment differently from the physical environment. B. Obligation to Separate Content It is also important that content prepared for the public and healthcare professionals in a digital environment is always separated from each other. Pharmaceutical companies may establish websites for the purpose of providing information, but the content prepared for the public and healthcare professionals must always be separated on these pages. Sections of the website accessible to the general public may include current medical practices, health, diseases, and treatment methods of a general nature, but this information must be scientific in nature and must not include any indirect or direct product promotion or mention any drug names; recommendations such as “The information on this site is not a substitute for consulting a doctor or pharmacist” should be included; When designing websites, it must be ensured that only doctors, dentists or pharmacists have access to sections intended for promotion or information to healthcare professionals, and it must be stated that the relevant sections are intended only for doctors, dentists and pharmacists. The obligation to separate content addresses the difficulties arising from the technical characteristics of the digital environment. The presence of content aimed at different target audiences on the same platform in the digital environment increases the risk of circumventing the advertising ban. C. Specific Issues in Social Media and Mobile Applications Pharmaceutical companies' social media pages are directly accessible to the public, and it is important that they always refrain from promoting medicines due to situations such as not knowing who is accessing the relevant page or not being able to distinguish between pharmacists, doctors, or dentists. When downloading mobile applications, names that include product names or information that could promote the product should be avoided. Social media and mobile applications constitute the most problematic areas of promotion in the digital environment. The public nature of these platforms and the difficulty of distinguishing users make compliance with regulations difficult.   VII. LEGAL ANALYSIS OF THE PROHIBITION ON COVERT ADVERTISING In addition to all these specific regulations, it should not be forgotten that covert advertising that circumvents legal restrictions is also prohibited. The prohibition of covert advertising is of critical importance in terms of protecting the spirit of legislation and preventing circumvention of legal regulations. This prohibition constitutes a complementary protection mechanism alongside explicit regulations. The concept of covert advertising is open to broad interpretation, which may create legal uncertainty. Determining which activities constitute covert advertising is a matter that must be assessed based on the specific characteristics of each case. Legislation has not established objective criteria in this regard, and the assessment is largely left to the discretion of the administrative authority.   VIII. THE NORMATIVE STRUCTURE AND EFFECTIVENESS OF THE SANCTION SYSTEM A. Graduated Sanction System The licence/permit holder is first warned by the Authority. If any non-compliant act is detected within one year of the warning date, the holder is prohibited from carrying out promotional activities for three months. If any non-compliant act is detected again within one year of the date of the three-month prohibition, the holder is prohibited from carrying out promotional activities for one year. Product promotion representatives are also first warned by the Authority; if any non-compliant act is detected within one year following the date of the warning, the Institution shall suspend the relevant person's certificate of competence for three months. If any non-compliant act is detected again within one year following the date of the three-month suspension of the certificate of competence, the relevant person's certificate of competence shall be suspended for one year. The graduated sanction system reflects the principle of proportionality and provides increasing deterrence for repeated violations. The system has a structure that progresses from warning to short-term ban to long-term ban. B. Sanctions Against Healthcare Professionals Disciplinary proceedings are initiated against healthcare professionals who violate the Regulation by their affiliated institution or professional organization. The regulation of sanctions against healthcare professionals within the framework of disciplinary law emphasizes the dimension of professional ethics and responsibility. This regulation demonstrates that sanctions can be applied not only to pharmaceutical companies but also to healthcare professionals who engage in conduct that violates the legislation.   CONCLUSION AND EVALUATION The legal framework governing the promotion of pharmaceuticals and medicinal products in Türkiye is a comprehensive regulatory system that aims to strike a balance between protecting public health and commercial freedom. While legislation generally prohibits promotion to the public, it imposes strict rules on promotion to healthcare professionals. The fundamental approach of the legislation reflects a paternalistic understanding of protection. This approach aims to prevent individuals from making decisions regarding drug use under the influence of medical information asymmetry and advertising, and to position healthcare professionals as “gatekeepers” of decisions regarding drug use. However, the legislation contains some structural problems and implementation difficulties. Firstly, the lack of concretisation of subjective criteria (reasonableness, absence of excessiveness) creates uncertainty in practice. Secondly, the timeliness of the legislation is questionable in the face of rapidly developing technological capabilities for promotion in the digital environment. Thirdly, the lack of objective criteria for enforcing the ban on surreptitious advertising creates difficulties in the monitoring and sanctioning processes. The effectiveness of the legislation depends not only on the existence of rules but also on their effective implementation, monitoring and continuous updating. Increasing the capacity of monitoring mechanisms, strengthening the deterrent effect of sanctions and adapting the legislation to technological developments appear necessary to improve the effectiveness of the system. In conclusion, while Turkish pharmaceutical advertising legislation constitutes an important regulatory framework serving the purpose of protecting public health, the structural issues outlined above must be addressed, and the system must be continuously improved.

The Republic of Türkiye occupies a unique position in the global investment landscape, serving as a geographic and economic bridge between Europe, Asia, and the Middle East. For foreign investors contemplating market entry, Türkiye offers a liberal foreign direct investment (“FDI”) framework grounded in principles of national treatment and freedom of investment. Notwithstanding this liberal framework, successful market entries into Türkiye by foreign investors require careful navigation of local legal requirements, sector-specific regulations, competition law clearances, and knowledge of distinctive Turkish business practices. This article examines the legislative framework, market entry mechanisms, regulatory requirements, and transactional considerations that shape cross-border investment activity in Türkiye, providing practical guidance for foreign investors evaluating entry strategies.   The Legislative Framework and Fundamental Principles Fundamental Principles of the FDI Regime Türkiye's FDI regime rests upon Law No. 4875 on Foreign Direct Investments, enacted in 2003 as part of comprehensive economic reforms. Law No. 4875 establishes the definitional scope of foreign direct investment, encompassing business activities conducted by foreign investors through establishing companies, acquiring shares in existing companies, opening branches or liaison offices, and participating in joint ventures. Türkiye’s foreign direct investment framework operates according to four foundational principles:   The principle of equal treatment: Law No. 4875 guarantees foreign investors the same legal rights and obligations as Turkish nationals. This national treatment standard prohibits discrimination based on nationality in company formation, share acquisition, property ownership, and access to incentive programs. Turkish investment regime permits; 100% foreign ownership in most sectors without requiring local partners or minimum Turkish shareholding, representing a substantial competitive advantage relative to jurisdictions maintaining foreign ownership caps or mandatory joint venture requirements. The equal treatment principle extends to dispute resolution, ensuring foreign investors access to Turkish courts and arbitration on the same basis as domestic parties.  100% foreign management, as the managers of a Turkish entity being solely foreign persons. That said, in terms of fully foreign-managed companies operating in Türkiye, (i) practical considerations may require additional local management support and (ii) Turkish banks’ anti-money laundering regulations and know-your-customer requirements under Banking Regulation and Supervision Agency guidelines may impose additional requirements. The principle of freedom to invest: There are no pre-approval requirements specifically required for foreign direct investment. Foreign investors may establish companies, acquire shares in existing Turkish entities, and open branches or liaison offices without obtaining prior governmental authorization. Privileged sectors including broadcasting, defence, education and aviation may impose limitations on foreign ownership percentages or require specific governmental approvals, which shall be identified prior to transaction planning. The principle of freedom of transfer: Foreign investors may freely transfer abroad profits, dividends, proceeds from share sales or liquidation, compensation for expropriation, and payments arising from licensing or technical assistance agreements. These transfers are subject to standard tax withholding obligations and must comply with general anti-money laundering and counter-terrorism financing regulations applicable to all cross-border payments. The principle of protection against expropriation: The Turkish Constitution permits expropriation only for public interest purposes, subject to prior payment of compensation reflecting real value. Law No. 4875 reinforces these protections, guaranteeing that any expropriation of foreign investments must comply with due process requirements and provide prompt, adequate, and effective compensation calculated at fair market value.   Regulatory Approvals  Notwithstanding the generally liberal character of Türkiye’s FDI regime, certain sector-specific restrictions and approval requirements merit careful attention during investment planning. These can be summarized as follows: Sector Specific Approvals: Banking, insurance, capital markets, energy, telecommunications, mining, and certain other sectors require specific licenses or authorizations before commencing operations. Merger Control: Competition law clearance requirements constitute a critical consideration for merger and acquisition transactions. Turkish Competition Law No. 4054 is modelled substantially on European Union competition law and requires notification and approval of transactions that result in a permanent change of control and exceed specified turnover thresholds. Under the recently revised framework, a merger or acquisition transaction is subject to notification to the Turkish Competition Authority where; the aggregate Turkish turnover of the transaction parties exceeds TRY 3 billion, and the Turkish turnovers of at least two of the transaction parties each exceed TRY 1 billion, or in the case of acquisitions, the Turkish turnover of the assets or activities subject to the transaction, or in merger transactions, the Turkish turnover of at least one of the transaction parties exceeds TRY 1 billion, and the worldwide turnover of at least one of the other transaction parties exceeds TRY 9 billion. In case of transactions involving technology undertakings, TRY 1 billion threshold shall be applied as 250 million TRY with respect to the transaction party subject to the transfer in merger transactions where at least one of the transaction parties is an undertaking established in Türkiye and in transactions concerning the acquisition of such undertakings. Governmental Notification Requirements: Foreign investors must also complete mandatory notifications regarding company establishment, share transfers, and capital increases. This notification-based system, administered through the Foreign Capital Information System operated by the Ministry of Industry and Technology, requires only post-investment reporting for statistical and monitoring purposes. Whilst these notifications do not prevent transaction closing, failure to comply may result in administrative penalties and complications in subsequent dealings with governmental authorities.   Legal Structures for Market Entry Foreign investors entering the Turkish market have several structural options, each suited to different levels of commitment and operational objectives. The three primary mechanisms—company incorporation, branch offices, and liaison offices—offer distinct legal, operational, and strategic characteristics. Full Legal Entity (Company) Incorporation Establishing a separate legal entity, represents the most comprehensive market entry option. This structure creates an independent Turkish legal entity, separate from the foreign parent company, which limits liability exposure to the entity's own assets and obligations. This option provides the greatest operational flexibility and is the preferred structure for sustained, full-scale operations and growth in the Turkish market. Foreign investors establishing operations in Türkiye must select an appropriate legal entity structure, balancing considerations including minimum capital requirements, governance complexity, operational flexibility, tax efficiency, and future strategic options. Turkish law recognizes several entity types suitable for foreign investment, each presenting distinct characteristics and implications. Mainly “joint stock company” or “limited liability company”, (which are both limited liability companies in terms of shareholder liability with certain distinctions) are considered in practice. Selection between joint stock company and limited liability company structures requires evaluating several factors: Joint Stock Company: Foreign investors pursuing substantial investments requiring significant capital deployment and local operations, typically select “joint stock” company structures. The enhanced flexibility, favourable tax treatment, and facilitation of future strategic transactions justify the additional administrative requirements. Share transfer mechanics favour joint stock companies for investors anticipating future merger and acquisition activity or eventual exit through sale. Limited Liability Company: Smaller investments or direct subsidiaries of global entities more commonly employ “limited liability company” structures, benefiting from reduced complexity and lower capital requirements. Governance complexity and administrative burden favour limited liability companies for investors prioritizing operational simplicity. Branch Office: A branch office operates as an extension of the foreign parent company rather than as a separate legal entity. Branch offices are suited for situations where investors wish to conduct direct commercial operations without establishing a separate legal entity and test the market before committing to full-scale investment through incorporation.  Liaison Office: Liaison offices are usually established for a limited period of time prior to initiating any commercial activities and to test the market. Liaison offices are initially granted permits for a limited term of maximum 3 years typically, and the permit is solely for the scope of activities declared in their application. Liaison offices serve preparatory and auxiliary functions only and are strictly prohibited from engaging in commercial activities or generating revenue in Türkiye.   Strategic Market Entry Planning  Having selected an appropriate legal structure (as outlined in Section II), foreign investors must determine their strategic market entry approach. The principal strategies comprise greenfield investment, mergers and acquisitions, and joint ventures, each presenting distinct advantages, risks, and regulatory implications depending on investment timeline, risk tolerance, capital availability, and sector characteristics:   Greenfield Investments  Greenfield investments involve establishing a new legal entity in Türkiye, providing complete operational control and enabling investors to build operations according to their specifications without inheriting legacy issues. This approach suits investors pursuing long-term strategic market presence. The greenfield approach offers several advantages for investors to exercise complete control over business model, operational procedures, corporate governance, and organizational culture from inception. The entity structure can be optimized for the specific business activity, ownership structure, and future growth plans. Greenfield investments require careful planning from the onset, especially in terms of company incorporation, obtaining necessary permits and licenses, recruiting personnel, and building customer relationships, depending on the type of business. Accordingly, careful consideration of market entry timelines and pre-planning of local requirements is essential.   Mergers and Acquisitions  Acquisition of existing Turkish companies provides accelerated market access, immediate revenue generation, and the ability to leverage established customer relationships, operational infrastructure, and in regulated sectors direct access to existing licenses and permits. Direct acquisition offers distinct advantages: As the market entry occurs rapidly, immediate access to established operations, customer base, revenue streams, and market position is achieved. Existing licenses, permits, and regulatory approvals transfer with the acquisition, avoiding potentially lengthy licensing processes. That said, mergers and acquisitions require careful management as to legacy liabilities including undisclosed obligations, contingent liabilities, tax exposures, and litigation risks which may materialize post-closing. Compliance issues including regulatory violations, employment law non-compliance, or intellectual property deficiencies may require remediation. Comprehensive due diligence constitutes the primary risk mitigation mechanism in acquisition transactions. Due diligence scope and methodology must be tailored to the specific transaction, target company, and sector, balancing thoroughness against practical constraints including seller cooperation, time limitations, and cost considerations. Transaction documentation must provide contractual protections addressing risks identified during due diligence and allocating risk appropriately between buyer and seller. Share purchase agreements should include comprehensive representations and warranties, covering corporate organization, title to shares, financial condition, assets, contracts, employment matters, compliance, and litigation.   Joint Ventures  Joint venture structures enable foreign investors to partner with Turkish or international companies, sharing investment risk, accessing local market knowledge and relationships, and in regulated sectors leveraging partners' existing licenses or expertise. Whilst Turkish law permits 100% foreign ownership in most sectors without requiring local partners, strategic or practical considerations may favour joint venture arrangements. Joint ventures prove particularly valuable in regulated sectors where local partners possess necessary licenses, regulatory relationships, or technical expertise.  Turkish law recognizes two principal joint venture structures: Equity joint ventures established through a special purpose vehicle company represent the most common approach. The joint venture partners establish a new Turkish company, typically structured as a joint stock company or limited liability company, with shareholdings, governance rights, and economic interests defined in the articles of association and a shareholders agreement.   Contractual joint ventures, established solely through a joint venture agreement without creating a separate legal entity, are less common in Turkish practice compared to equity joint ventures. This structure appears primarily in specific tender processes, particularly in the construction sector, where temporary cooperation for a defined project suits the parties' objectives. Turkish corporate law permits substantial contractual freedom in shareholders agreements, provided terms comply with mandatory statutory provisions. Essential provisions typically address; board composition, day-to-day governance, reserved matters requiring enhanced approval thresholds (such as business plans, significant capital expenditures), information and reporting rights, financial governance including dividend policies and funding obligations, and exit mechanisms through pre-emption rights, drag-along and tag-along provisions, and put/call options.   Sector Specific Considerations  The regulatory landscape differs substantially across industries, ranging from consumer protection compliance for retail businesses to comprehensive licensing regimes for regulated sectors. Understanding these requirements during the planning phase enables proper timeline and budget allocation. Foreign investors should consider the following industry-specific requirements during market entry planning:   Consumer-Facing Businesses Retail and consumer-facing market entries require extensive legal work during the launch phase. Turkish consumer protection law imposes detailed regulations governing consumer rights, advertising standards, promotional activities. Various additional rules also apply in terms of e-commerce operations. Product and service sales to consumers also require establishing comprehensive sales and after-sales service infrastructure. Consumer-related obligations including warranty service, product recalls, and complaint handling must be planned and implemented in accordance with Turkish consumer protection law. Certain product categories are subject to regulatory requirements mandating minimum after-sales service coverage. For example, automotive sector regulations require establishing at least 20 after-sales service locations distributed across seven different geographical regions of Türkiye. Retail operations must also comply with the Law on Protection of Personal Data No. 6698 (“KVKK”), as detailed in the technology section below, particularly regarding customer data processing, consent mechanisms, and data controller registration requirements.   Technology and Digital Platform Requirements Digital platforms and e-commerce operations must comply with specific regulations governing website disclosures, distance selling, and electronic communications, in addition to standard Turkish consumer law requirements. For instance; Electronic commerce platform obligations under the E-Commerce and Consumer Protection regulations, Social media platform regulations requiring local representation for platforms with significant Turkish users, Digital service tax obligations for digital advertising, content streaming, and online marketplace activities, Cybersecurity requirements for critical infrastructure providers, Local requirements as to handling of intellectual property. In terms of data protection requirements, whilst KVKK shares structural similarities with the GDPR, foreign investors should note that there are implementation differences in explicit consent requirements, data localisation considerations, and regulatory notification obligations that require careful compliance planning, especially for data-driven businesses.   Manufacturing and Industrial Operations Manufacturing facilities must obtain zoning approvals, environmental permits, and occupational health and safety certifications before commencing operations. The specific permits required depend on the type of manufacturing activity, with chemical production, food processing, and heavy industry facing particularly stringent environmental impact assessment and emissions control requirements. Workforce management requires advance planning, particularly regarding work permits for foreign personnel, compliance with occupational health and safety regulations, and collective labour agreement considerations in certain sectors. Access to government incentive programmes (including organised industrial zones, free zones, and technology development zones) requires coordination with relevant authorities and may involve commitments regarding employment levels, export ratios, or technology transfer.   Highly Regulated Sectors Regulated sectors including energy, mining, banking, financial technologies, payment services, and telecommunications demand particularly careful market entry planning; Specific licenses or authorizations are usually sought for incorporation or investments into regulated sectors; The target entity might be obligated to satisfy minimum capital requirements, technical capability standards, and fit and proper criteria for shareholders and managers. Early regulatory scoping with specialized local counsel is essential to identify licensing requirements, timelines, and compliance obligations. In some cases, regulatory requirements may make acquisition of an existing licensed entity more practical than applying for new licenses.   Conclusion  Successful market entry and investment in Türkiye requires careful navigation of local legal requirements, regulatory frameworks, and business practices that may differ from other jurisdictions. Early engagement with qualified Turkish legal, tax, and financial advisors, ideally at the same time with the transaction planning, enables proper structuring, identification of risks and opportunities, and localization of processes and documentation. Proper structuring from the outset, including selection of appropriate entity type, capitalization levels that satisfy both operational requirements and workforce deployment thresholds, governance mechanisms suited to the investment structure and objectives, and well-drafted shareholder arrangements, provides the foundation for successful operations and future strategic flexibility.
