A comprehensive analysis of shareholders' agreements (SHAs) in Turkish joint stock companies: legal nature, interaction with the articles of association, tag-along, drag-along, ROFR, put/call options, veto rights, mandatory limits of the Turkish Commercial Code (TCC), the case-law of the 11th Civil Chamber of the Court of Cassation and English law practice.
The Shareholders' Agreement (SHA) sits at the very centre of modern corporate law and international M&A practice and has grown increasingly complex over the past two decades. Although the Turkish Commercial Code (TCC) does not expressly regulate the SHA, it is recognised as valid under the Turkish Code of Obligations (TCO) and the principle of freedom of contract. An SHA governs the obligations that shareholders undertake vis-à-vis one another, the balance of power within the management of the company, share transfer mechanisms, exit scenarios and dispute resolution. This article examines in detail the legal nature of the SHA, its interaction with the articles of association, the operation of standard clauses, the mandatory limits imposed by the TCC, the settled approach of the 11th Civil Chamber of the Court of Cassation, international practice, and the practical points to which particular attention should be paid.
1. Legal Nature of the Shareholders' Agreement Under Turkish Law
An SHA is a multi-party contract of obligations concluded between the shareholders of a joint stock or limited liability company, governing the shareholders' rights and obligations within the company, the manner in which voting rights will be exercised, restrictions on share transfers, exit mechanisms and dispute resolution. Under Turkish law, the prevailing view is that the SHA constitutes an innominate (atypical) contract and derives its validity from the general provisions of the TCO and the principle of freedom of contract (TCO Article 26). The SHA is not expressly regulated in the TCC, but functions as an instrument complementing the company's articles of association. The limits of contractual freedom are set out in TCO Article 27, according to which any provision that is not contrary to public morals, public policy, personality rights or mandatory rules of law is considered valid. The increasing prevalence of the SHA under Turkish law is a consequence of the growing participation of foreign investors in Turkish companies, the rise of venture capital investments, joint venture structures and the institutionalisation of family businesses.
2. Distinction Between the Articles of Association and the Shareholders' Agreement
The distinction between the articles of association and the SHA is one of the fundamental issues of Turkish company law. The articles of association constitute the founding instrument of the company; they are registered and announced at the trade registry, produce effects vis-à-vis third parties, and bind the corporate organs and shareholders. The SHA, by contrast, is binding only between the parties under the law of obligations and cannot be directly invoked against third parties or the company itself - it operates on an inter partes basis. This distinction produces the following practical consequences: a share transfer effected in breach of the SHA may be accepted as valid by the corporate organs, whereas the other shareholders retain the right to claim damages against the breaching party or to enforce the contractual penalty mechanisms provided in the SHA. Provisions in the articles of association are subject to the mandatory limits of the TCC, while provisions in the SHA benefit from a broader margin of flexibility. It is therefore common practice to reflect critical provisions (such as transfer restrictions and pre-emption rights) in both instruments; core transfer restrictions and pre-emption rights are mirrored in the articles of association, while detailed governance and exit provisions are typically kept in the SHA.
3. Binding Force of the SHA and the Question of Enforceability Against the Company
The most contentious legal issue relating to the SHA concerns the scope of its binding force. According to the settled case-law of the 11th Civil Chamber of the Court of Cassation, an SHA produces effects only between the parties and cannot be directly invoked against the company. This approach is consistent with that of the Swiss Federal Tribunal and the German Federal Court of Justice (Bundesgerichtshof). The practical consequence of this approach is that a share transfer effected in breach of the SHA is accepted as valid vis-à-vis the company; it may be entered in the share ledger and the transferee acquires the status of shareholder. In case of breach of the SHA, the remaining shareholders' remedies are limited to claiming damages from the breaching party or enforcing the contractual penalty. To overcome this limited binding force, the practical solution is to reflect critical provisions in the articles of association as well, to structure share transfer restrictions as transfer restrictions (bağlam) under TCC Articles 492 et seq. and, where appropriate, to create in rem rights (such as pledges or usufructs) over the shares.
4. Standard SHA Clauses (I): Share Transfer Restrictions and Pre-emption Rights
Share transfer restrictions form the core of the SHA. Among the most common provisions of this kind are: first, right of first refusal (ROFR) clauses, under which a shareholder wishing to sell its shares to a third party must first offer them to the other shareholders on the same terms; second, right of first offer (ROFO) clauses, under which the selling shareholder is required to obtain an offer from the other shareholders first, and may sell to a third party only if it does not accept that offer; third, lock-up clauses, which may prohibit any share transfer for a specified period; fourth, permitted transfer exceptions, which typically exempt intra-group transfers and transfers to family members from the ROFR. The key considerations for the effective operation of these clauses are the form of the transfer notice, the applicable time periods, the pricing mechanism (whether based on the third-party offer or on an independent valuation), and the clear articulation of the sanctions applicable in case of breach.
5. Standard SHA Clauses (II): Tag-Along and Drag-Along Rights
Tag-along and drag-along rights, among the most critical provisions of international M&A practice, are designed to balance the interests of majority and minority shareholders. Under a tag-along right, the majority shareholder wishing to sell a controlling stake is required to allow minority shareholders to sell their shares on the same terms - protecting minority shareholders from being left behind when control changes. Under a drag-along right, where the majority shareholder's shares are being sold to a buyer above a certain threshold, the majority may compel the minority to join in the sale on the same terms. This right allows the majority to guarantee a 100 per cent sale in exit scenarios and eliminates the obstacles a strategic buyer would otherwise face in acquiring the minority stake. In drafting tag-along and drag-along clauses, the following elements require particular attention: trigger thresholds, pricing mechanisms, exemptions (permitted transfers, intra-group transfers), time limitations, and clear procedural steps. Poorly drafted tag/drag clauses can prove unenforceable in practice and lead to significant disputes.
6. Standard SHA Clauses (III): Put and Call Options and Exit Mechanisms
Put and call options are mechanisms that regulate the rights of shareholders to sell or purchase shares upon the occurrence of certain events. A put option grants the option holder the right to sell its shares to another shareholder upon the occurrence of a specified event. A call option, in contrast, grants the option holder the right to purchase the other shareholder's shares upon the occurrence of a specified event. Common trigger events for such options include breach of contract, management deadlock, achievement or failure to achieve specified financial targets, an IPO process, and bankruptcy or composition proceedings. Pricing may be based on a fixed formula (multiple), an independent valuation, market value or a penal price (a discounted price applicable in case of breach). The validity of option agreements under Turkish law is well established, and the general provisions of TCO Articles 211 et seq. governing sales undertakings apply. In the event of an IPO, automatic exit mechanisms, liquidation preferences and drag-along rights must be regulated with particular care in the SHA.
7. Standard SHA Clauses (IV): Governance, Veto Rights and Reserved Matters
The governance section of the SHA provides detailed regulation of the composition of the board of directors, appointment rights, veto rights and reserved matters. The number of board members, appointment ratios (for example, a 30 per cent shareholder's right to appoint one member) and the appointment of independent directors may be regulated in the SHA. Reserved matters typically cover amendments to the articles of association, capital increases or reductions, mergers, demergers, changes of legal form, material asset disposals, adoption of the annual budget, borrowing limits, execution of material contracts, appointment of senior executives, and changes to the company's field of activity. Decisions on such matters may require a super-majority or the consent of the minority shareholder. Reserved matters mechanisms ensure that the minority shareholder has a voice in the company's fundamental strategic decisions and prevent arbitrary action by the majority. In addition, deadlock resolution mechanisms are essential: mediation, expert determination, Russian roulette, Texas shoot-out or comparable mechanisms are commonly employed.
8. Mandatory Limits of the TCC and the Article 340 Question
The most critical legal boundary in drafting an SHA is the mandatory provisions of the TCC. Under TCC Article 340, the articles of association may only derogate from the provisions of the TCC on joint stock companies to the extent expressly permitted by law, and mandatory provisions of other statutes are reserved. This provision embodies a strict typology principle in the law of joint stock companies. However, the case-law of the 11th Civil Chamber of the Court of Cassation accepts that Article 340 applies only to the articles of association, and that the SHA may accommodate more flexible arrangements within the scope of contractual freedom. Nevertheless, provisions in the SHA must not contradict the fundamental structural features of the company; clauses that effectively strip the board of directors of its powers, undermine the essential attributes of shareholder rights, or unlawfully restrict voting rights may be treated as invalid. Furthermore, mandatory provisions such as TCC Article 435 (prohibition of transfer of voting rights), TCC Article 436 (prohibition on voting on matters concerning the shareholder's own interest) and TCC Article 480 (prohibition on falling below the minimum statutory capital) also directly affect the SHA.
9. Non-Compete and Non-Solicitation Provisions
Non-compete and non-solicitation clauses restricting shareholders from competing with the company's business and from soliciting the company's employees, customers or suppliers are common features of SHAs. Although the validity of such clauses is assessed under a framework distinct from TCO Articles 444-447 (non-competition in employment contracts), it is accepted that they must remain within reasonable limits as to duration, subject matter and geographical scope. The case-law of the Court of Cassation invalidates, in whole or in part, non-compete clauses that unreasonably restrict a shareholder's economic freedom, or are unlimited in time or scope. In international practice, non-compete durations are typically set at between two and five years from the exit date; the geographical scope is limited to the region in which the company actually operates; and the subject-matter scope is confined to the company's principal commercial activity. Non-solicitation clauses generally cover the poaching of employees, customers and suppliers, and are supported by contractual penalties for breach.
10. Information Rights, Reporting and Transparency Obligations
SHAs commonly include detailed regulation of the minority shareholder's information rights beyond the minimum standard prescribed by the TCC. Whereas TCC Article 437 permits a shareholder to request information at general meetings, an SHA may impose an obligation to provide the shareholders with the annual budget, monthly financial reports, audit reports, material contracts and management reports on a periodic basis. In structures involving foreign investors and venture capital funds, SHAs additionally provide for monthly MIS reports, KPI monitoring, auditor appointment rights, mandatory independent audit and observer appointment rights. The balance between information rights, commercial confidentiality and the non-compete regime must be carefully calibrated; safeguards for the sharing of sensitive information (NDAs, need-to-know principles, secure data rooms) should be expressly regulated.
11. Dispute Resolution: Mediation, ISTAC, ICC and Choice of Forum
The dispute resolution mechanisms provided in an SHA are of significant practical importance. Under Turkish law, mandatory pre-litigation mediation applies to commercial disputes under Law No. 7155; SHAs typically include arbitration clauses that go beyond this requirement. Popular choices of arbitral institution for internationally oriented SHAs include the Istanbul Arbitration Centre (ISTAC), the International Chamber of Commerce (ICC), the London Court of International Arbitration (LCIA) and the German Arbitration Institute (Deutsche Institution für Schiedsgerichtsbarkeit - DIS). When drafting arbitration clauses, the seat of arbitration (Istanbul, Geneva, Paris or London), the language of arbitration (Turkish or English), the applicable substantive law, the number of arbitrators (one or three), emergency arbitrator provisions and interim relief mechanisms must all be expressly addressed. Turkish law is typically chosen as the substantive law, although Swiss or English law may also be selected in certain structures. Under Article 24 of the Turkish Private International Law Act (MÖHUK) No. 5718, choice of law is generally valid, subject to the mandatory rules of the TCC.
12. Settled Case-Law of the 11th Civil Chamber of the Court of Cassation
The settled case-law of the 11th Civil Chamber of the Court of Cassation on SHAs constitutes a key reference point in this area. The essential holdings of this line of authority may be summarised as follows: SHAs produce effects only between the parties and cannot be invoked against the company or third parties; share transfers effected in breach of the SHA are valid vis-à-vis the company, and the innocent shareholders' remedy is limited to a claim for damages against the breaching party; contractual penalties in the SHA are valid under TCO Articles 179 et seq., but the court has the power to reduce excessive penalties; arbitration clauses in the SHA are valid and binding on the parties; and provisions of the SHA may not contradict the articles of association, with any such contradictory provisions being invalid in favour of the articles of association. In practice, this case-law dictates a specific drafting strategy: critical share transfer restrictions, pre-emption rights and transfer restrictions should be reflected in the articles of association as well; and parallel amendments to the articles of association should be carried out in order to mitigate the risks of relying solely on the SHA.
13. The Influence of English Law and International SHA Practice
The structure of SHAs in international M&A and venture capital transactions has been largely shaped by English common law. Most SHAs drafted by Turkish lawyers follow the tripartite English M&A structure comprising the SPA (Share Purchase Agreement), SSA (Share Subscription Agreement) and SHA. This structure adapts to Turkish law the concepts of representations and warranties, indemnities, MAC (Material Adverse Change) clauses, disclosure schedules, deferred consideration, earn-out mechanisms and escrow arrangements. Under Turkish law, representations and warranties may be assessed within the framework of statutory warranty against defects and warranty undertakings under TCO Articles 219 et seq., but may also be structured more broadly by virtue of freedom of contract. Indemnity clauses under Turkish law are typically assessed as guarantee contracts under TCO Article 128; limitation periods, caps and de minimis / basket thresholds must be drafted with care.
14. SHAs in Venture Capital Investments: Preference Rights and Anti-Dilution
SHAs involving venture capital (VC) and private equity (PE) investments include specific provisions favouring the investor. These include preferred share structures, liquidation preferences, conversion rights, anti-dilution protection mechanisms (full ratchet or weighted average), pre-emption rights and information rights. Under Turkish law, preferred shares are regulated by TCC Articles 478-479, and preferential rights may be granted in respect of dividends, liquidation proceeds and subscription rights. However, the wholesale replication under Turkish law of the English preferred shares structure is limited; certain aspects of preferred shares are therefore reflected in the articles of association, while the economic elements of the preferential rights are largely regulated as contractual undertakings in the SHA. Anti-dilution provisions must also be aligned with TCC Article 461 (pre-emption rights) in the articles of association.
15. Conclusion and Practical Recommendations
The SHA has taken on an increasingly strategic role under Turkish company law and has become indispensable, particularly in the participation of foreign investors, venture capital fund investments and the institutionalisation of family businesses. The practical considerations to be observed in drafting an SHA are as follows: critical provisions (transfer restrictions, pre-emption rights, veto rights) should be reflected in both the SHA and the articles of association; the mandatory provisions of the TCC and the case-law of the Court of Cassation should be tracked meticulously; tag-along, drag-along and option mechanisms should be drafted in a clear and enforceable manner; deadlock resolution mechanisms should be provided; non-compete clauses should be kept within reasonable limits as to duration, subject matter and geographical scope; arbitration clauses should be drafted clearly as to institution, seat, language and number of arbitrators; contractual penalties should be set at levels that will not be considered excessive; preferred share structures should be adapted to Turkish law; and all provisions should be aligned in a consistent manner with the SPA, SSA and any related option agreements. The SHA is not merely a technical contract; it is the legal architecture of the trust relationship between shareholders, and its drafting requires careful foresight of the parties' long-term interests, exit scenarios and contingencies.
