Introduction
Public offering in Turkey is one of the most important methods for companies to raise capital, broaden their shareholder base, increase corporate visibility and access institutional and retail investors. A public offering, especially an initial public offering, is not only a financial transaction but also a highly regulated legal process. Companies that intend to offer shares, debt instruments or other capital market instruments to the public must comply with Turkish Capital Market Law, the regulations of the Capital Markets Board of Türkiye and, where relevant, the rules of Borsa İstanbul.
The main legislation governing public offerings in Turkey is Capital Markets Law No. 6362. The law introduced a modern regulatory structure for Turkish capital markets and aims to strengthen investor protection, market transparency and confidence in financial markets. The Capital Markets Board of Türkiye, known as the CMB in English and SPK in Turkish, is the principal authority responsible for regulating and supervising public offerings and capital market activities in Turkey. The CMB’s official materials identify public offering registration, prospectus standards, disclosure requirements, supervision of offering-related publications and regulation of issuances as core primary market functions.
A public offering in Turkey requires careful legal preparation. The process usually includes corporate restructuring, financial reporting, legal due diligence, preparation of a prospectus, CMB application, CMB review and approval, public disclosure, sales and distribution, possible Borsa İstanbul listing and post-offering compliance. Any failure in this process may result in administrative sanctions, civil liability, criminal exposure and investor claims.
What Is a Public Offering in Turkey?
A public offering generally refers to an invitation made to the public for the purchase of capital market instruments and the sale of such instruments following that invitation. In practical terms, a public offering may involve the sale of newly issued shares, existing shares held by current shareholders, debt securities or other capital market instruments to a broad group of investors.
In Turkey, the public character of the transaction is legally significant. If a company collects money from the public by promising shares, partnership rights, dividends or investment returns, the transaction may fall within the scope of capital market legislation. The CMB has publicly warned that collecting money from the public through shares, partnerships or similar structures without fulfilling the prospectus or issue document obligations may trigger serious legal consequences.
Therefore, companies must not treat a public offering as a simple marketing campaign or private fundraising effort. Once the public is targeted, Turkish securities law requirements may apply. This is particularly important for start-ups, real estate projects, digital platforms, energy ventures, crowdfunding-style models and companies using social media to attract investors.
Main Legal Framework for Public Offerings in Turkey
The legal framework for public offerings in Turkey is based on Capital Markets Law No. 6362 and the secondary legislation issued by the CMB. The CMB’s official legislation page lists the core regulations relevant to capital market instruments, including the Communiqué on Prospectus and Issue Document II-5.1, the Communiqué on Sales of Capital Market Instruments II-5.2, the Communiqué on Shares VII-128.1, regulations on debt securities, lease certificates, foreign capital market instruments and other capital market products.
For a share offering or IPO, the most relevant rules usually include Capital Markets Law No. 6362, the Prospectus and Issue Document Communiqué, the Sales of Capital Market Instruments Communiqué, the Shares Communiqué, corporate governance rules, financial reporting rules, material event disclosure rules and Borsa İstanbul listing rules. Depending on the nature of the issuer and the instrument, additional regulations may apply.
The CMB has published English translations of many communiqués relevant to global institutions and investors, including the Prospectus and Issue Document Communiqué, Sales of Capital Market Instruments Communiqué, Communiqué on Shares, Communiqué on Corporate Governance, Communiqué on Material Events Disclosure and investment services regulations.
The Role of the Capital Markets Board of Türkiye
The CMB is the central regulatory authority in the Turkish public offering process. It reviews prospectuses and issue documents, supervises issuers and intermediary institutions, determines disclosure standards, oversees offering-related advertisements and announcements, regulates capital market instruments and protects investors.
The CMB’s role should not be misunderstood. CMB approval is an essential legal requirement for many public offerings, but approval does not mean that the CMB guarantees the commercial success of the offering, the financial strength of the issuer or the future price performance of the securities. Under the Capital Market Law framework, the Board approves a prospectus when the information is found to be consistent, comprehensible and complete according to the applicable prospectus standards; the approval does not mean that the Board guarantees the accuracy of the information.
This principle is crucial for both issuers and investors. Issuers remain responsible for the accuracy and completeness of the information disclosed. Investors must understand that regulatory approval does not eliminate investment risk.
Prospectus Requirement in Public Offerings
The prospectus is the central legal document in a public offering in Turkey. It is prepared to inform investors about the issuer, the securities, the rights attached to the securities, risk factors, financial condition, business activities, management structure, use of proceeds, legal disputes and other material information.
The Communiqué on Prospectus and Issue Document II-5.1 regulates the preparation, approval and publication of prospectuses and issue documents, as well as advertisements and announcements related to them. Its official text states that the communiqué sets out principles concerning the preparation, approval and promulgation of prospectuses and issue documents pursuant to Law No. 6362.
A prospectus is not a promotional brochure. It is a legal disclosure document. It must be drafted with precision, supported by due diligence and reviewed by legal, financial and technical advisors. Misleading, incomplete or inconsistent information may expose the issuer, directors, selling shareholders, intermediary institutions and other responsible persons to liability.
A proper prospectus usually includes detailed information on the company’s business model, financial statements, capital structure, shareholding structure, risk factors, management, related-party transactions, material contracts, litigation, regulatory risks, dividend policy and the intended use of offering proceeds. The risk factors section is especially important because it informs investors about sectoral, financial, operational, legal and market risks.
Issue Document and Non-Public Offering Transactions
Not every issuance is a public offering. Turkish capital market legislation also recognizes issuances without public offering, private placements and sales to qualified investors. In these transactions, a full public offering prospectus may not always be required, but an issue document and CMB approval may still be necessary depending on the instrument and structure.
The distinction between a public offering and a non-public issuance is legally important. A company may prefer a qualified investor sale because it may be faster and less burdensome than a full public offering. However, this does not mean that the transaction is completely unregulated. Sale restrictions, investor classification, disclosure obligations, CMB applications and issue document requirements must be reviewed carefully.
The Sales of Capital Market Instruments Communiqué also includes rules on sales periods for issuances without public offering and common provisions on sales periods. For example, the communiqué contains specific rules on when sales may begin and how long they may continue in certain non-public offering structures.
Legal Steps of a Public Offering in Turkey
A public offering in Turkey generally follows several legal and practical stages. Although the details vary depending on whether the transaction is an IPO, secondary offering, capital increase, debt issuance or another type of offering, the main stages are usually similar.
The first stage is internal preparation. The company must review whether it is legally, financially and operationally ready for a public offering. This includes reviewing articles of association, board structure, shareholding arrangements, privileged shares, capital structure, financial statements, litigation risks, employment liabilities, tax issues, intellectual property rights and material contracts.
The second stage is appointment of advisors. Public offerings usually require an intermediary institution, legal counsel, independent auditors and sometimes valuation experts or sector consultants. The intermediary institution plays a central role in structuring the offering, communicating with investors, assisting with documentation and managing the sales process.
The third stage is legal and financial due diligence. Due diligence aims to identify risks that must be disclosed in the prospectus or resolved before the offering. Hidden liabilities, shareholder disputes, defective corporate resolutions, unregistered intellectual property, tax exposure, regulatory violations or major litigation may affect the success of the offering.
The fourth stage is preparation of the prospectus and application documents. These documents must comply with CMB standards and must be internally consistent. Financial statements, risk factors, management explanations, legal disclosures and offering terms must be aligned.
The fifth stage is submission to the CMB. The CMB reviews the application and may request revisions, additional information or supporting documents. The approval process is not merely formal; the CMB examines whether the prospectus satisfies the applicable standards.
The sixth stage is publication, marketing and sales. After approval, the prospectus is published through the required channels, and the offering is conducted in accordance with the approved documents and applicable sales rules.
The final stage is post-offering compliance. If the issuer becomes a public or listed company, it must comply with ongoing disclosure, corporate governance, financial reporting and investor relations obligations.
Public Offering of Shares and IPOs
An initial public offering is the first sale of a company’s shares to the public. In Turkey, IPOs are usually conducted through a capital increase, sale of existing shares or a combination of both. In a capital increase, the company issues new shares and receives the offering proceeds. In a sale of existing shares, current shareholders sell part of their shares and receive the proceeds.
The Communiqué on Shares VII-128.1 is one of the key regulations for share offerings. The CMB’s communiqués list confirms that the Communiqué on Shares is among the main capital market regulations relevant to offerings and issuers.
Before an IPO, the company should review its corporate governance structure. Public investors are more likely to trust companies with transparent management, clear financial reporting, independent oversight and fair treatment of minority shareholders. A company that is legally disorganized may face difficulties during the CMB review process and investor marketing stage.
IPO preparation also requires careful management of existing shareholders. Share transfer restrictions, privileged shares, shareholder agreements, pre-emption rights and board nomination rights must be analyzed. Some structures may need to be amended before public offering.
Sales and Distribution Rules
The public offering process does not end with prospectus approval. The actual sale and distribution of capital market instruments are also regulated. The Communiqué on Sales of Capital Market Instruments II-5.2 is listed by the CMB as one of the core regulations concerning capital market instruments.
Sales rules may concern offering methods, allocation principles, investor categories, distribution, delivery, pricing, sales periods and disclosure of changes. These rules are designed to ensure that investors are treated fairly and that the offering is conducted transparently.
In practice, sales may be made through fixed-price sale, book-building or other methods permitted under the applicable framework. The offering structure should be selected according to the issuer’s profile, investor demand, market conditions and regulatory requirements.
The issuer and intermediary institution must ensure that all marketing materials, investor presentations and announcements are consistent with the approved prospectus. Statements promising guaranteed returns, risk-free profit or unrealistic price performance may create serious legal risks.
Advertising and Marketing Restrictions
Advertising is a sensitive issue in Turkish public offerings. Public offering communications must not mislead investors, exaggerate expected returns or omit material risks. The Prospectus and Issue Document Communiqué expressly covers advertisements and announcements related to prospectuses and issue documents.
Companies should avoid informal investor solicitations before completing the required legal process. This is especially important in social media campaigns, online investment platforms, YouTube promotions, Telegram groups, WhatsApp groups and influencer marketing. A message that appears to be a simple promotional announcement may be treated as part of a public solicitation if it invites the public to invest.
The CMB has warned that unauthorized public fundraising through internet, social media and digital platforms may harm investors and may fall within the scope of capital market violations where money is collected from the public under partnership, share or dividend promises without the required approved prospectus or issue document.
CMB Approval Process
The CMB approval process is one of the most critical stages of a public offering in Turkey. The issuer submits the prospectus, application documents, corporate approvals, financial statements, intermediary institution documents and other required materials to the CMB.
The CMB reviews whether the prospectus is consistent, comprehensible and complete according to the applicable standards. If the CMB identifies deficiencies, it may request corrections, additional disclosure or amendments. The issuer must respond carefully and accurately. A weak response may delay the process or create further regulatory questions.
CMB approval should be viewed as a disclosure-based regulatory review. It is not an endorsement of the issuer’s investment quality. Therefore, prospectus drafting must be accurate, balanced and legally defensible. The risk factors should not be treated as a formality. They should reflect the actual legal, financial and operational risks of the issuer.
Borsa İstanbul Listing
In many public offerings, especially IPOs, the issuer also seeks listing and trading of its shares on Borsa İstanbul. Listing brings additional requirements concerning financial criteria, corporate structure, free float, public disclosure, investor relations and exchange rules.
CMB approval and Borsa İstanbul listing are related but distinct processes. A company may need to satisfy both capital market regulatory requirements and exchange listing conditions. Therefore, IPO planning should be coordinated with both CMB and Borsa İstanbul expectations.
Once listed, the company becomes subject to continuous market discipline. Share price movements, investor expectations, analyst reports, public disclosures and corporate actions become part of the company’s daily legal and commercial environment. For this reason, an IPO should not be viewed as the end of a process but as the beginning of a new regulatory status.
Investor Protection in Public Offerings
Investor protection is the main reason why public offerings are regulated. In a public offering, investors rely heavily on information disclosed by the issuer and reviewed through the regulatory process. Most retail investors do not have direct access to company records, internal reports or management discussions. Therefore, the prospectus and public disclosures must provide reliable information.
Investor protection mechanisms include prospectus approval, disclosure rules, financial reporting, independent audit, sales regulations, intermediary institution duties, market abuse rules and post-offering public disclosure obligations.
However, investor protection does not mean that investors are protected against all losses. Capital market investments involve risk. Share prices may decrease after an IPO. Market conditions may change. The issuer’s business may perform worse than expected. The law protects investors against misleading information, unauthorized offerings and unlawful conduct, but it does not guarantee investment returns.
Liability Risks in Public Offerings
Public offerings create significant liability risks. If the prospectus contains false, misleading or incomplete information, investors may claim that they made investment decisions based on defective disclosure. Depending on the facts, liability may arise for the issuer, directors, selling shareholders, intermediary institutions, auditors or other responsible persons.
Directors and managers must be especially careful when approving prospectus content. They should ensure that financial information, litigation disclosures, risk factors, related-party transactions and use-of-proceeds statements are accurate. A company cannot hide material risks to make the offering more attractive.
Intermediary institutions also have duties. They should assist in preparing accurate documentation, ensure compliance with sales rules and avoid misleading promotional conduct. If they fail to fulfill their professional obligations, they may face regulatory and civil consequences.
Criminal Consequences of Unauthorized Public Offerings
Unauthorized public offerings are not merely administrative violations. They may also trigger criminal consequences. The CMB has warned that public offerings made without fulfilling the obligation to publish an approved prospectus, or issuances made without an approved issue document, may be subject to imprisonment and judicial fines under the Capital Markets Law framework.
This is particularly important for companies or individuals who collect money from the public under the name of shares, partnerships, investment opportunities or profit-sharing arrangements. If the structure actually involves capital market instruments or public solicitation, the absence of CMB approval may create serious legal exposure.
Entrepreneurs should therefore seek legal advice before launching investment campaigns. The fact that a project is innovative, digital or structured outside traditional finance does not automatically remove it from capital market regulation.
Foreign Investors and Cross-Border Public Offerings
Foreign investors may participate in Turkish public offerings, and foreign issuers may also consider Turkish investors as part of their fundraising strategy. However, cross-border offerings require careful legal analysis.
If a foreign issuer markets securities to Turkish residents, uses Turkish-language materials, appoints local agents, holds investor meetings in Turkey or targets Turkish investors through digital channels, Turkish capital market rules may become relevant. The CMB’s legal framework includes regulations on foreign capital market instruments, depositary receipts and foreign investment funds, which shows that cross-border capital market activity is specifically addressed within the Turkish regulatory system.
Foreign investors should also consider tax, custody, foreign exchange, anti-money laundering and beneficial ownership rules. Institutional investors may have additional internal compliance obligations when participating in Turkish offerings.
Practical Compliance Checklist for Issuers
Before starting a public offering in Turkey, an issuer should complete a comprehensive legal review. The following issues should be examined carefully:
The company’s articles of association should be reviewed for compliance with capital market requirements. Share classes, privileges, transfer restrictions, board structure and general assembly procedures should be checked. Financial statements should be prepared in accordance with applicable standards and audited where required. Material contracts, litigation files, tax liabilities and regulatory permits should be analyzed. Related-party transactions should be documented and disclosed where necessary.
The issuer should also prepare an internal disclosure system. After becoming public, the company must be able to identify material events and disclose them properly. Investor relations, legal, finance and management teams should coordinate efficiently.
Risk factors should be drafted honestly. A prospectus that hides obvious risks may create serious liability. The better approach is to identify risks clearly and explain them in a balanced manner.
Practical Compliance Checklist for Investors
Investors considering participation in a Turkish public offering should review the approved prospectus carefully. They should focus not only on the company’s growth story but also on risk factors, financial condition, debt level, related-party transactions, litigation, use of proceeds and dividend policy.
Investors should understand that CMB approval does not guarantee profit. It means that the prospectus has passed the applicable regulatory review standards, not that the investment is risk-free. Investors should also avoid relying on social media rumors, unofficial price targets or unlicensed investment advice.
For significant investments, especially by foreign or institutional investors, legal and financial due diligence may be necessary. This is particularly true in offerings involving complex corporate structures, high-growth companies, regulated sectors, real estate portfolios, technology platforms or debt-heavy issuers.
Conclusion
Public offering in Turkey is a legally structured and highly regulated process. It provides companies with access to capital and investors with access to investment opportunities, but it also creates significant legal responsibilities. Capital Markets Law No. 6362, CMB communiqués and Borsa İstanbul rules must be followed carefully.
The CMB approval process is centered on disclosure, transparency and investor protection. The prospectus must be consistent, comprehensible and complete. Sales and marketing must be conducted in accordance with the approved documents and regulatory rules. Issuers, directors, selling shareholders and intermediary institutions must avoid misleading statements and incomplete disclosures.
For companies, a successful public offering requires early preparation, legal due diligence, accurate documentation, financial discipline and strong corporate governance. For investors, the key is to read the prospectus carefully, understand the risks and rely on official disclosures rather than market rumors.
In conclusion, public offering in Turkey is not merely a financing transaction. It is a legal transformation that places the issuer under a transparent, supervised and investor-facing regime. Any company planning a public offering, IPO, share sale, debt issuance or cross-border offering involving Turkish investors should obtain professional legal advice before taking any step.
