What is a Joint Stock Company?

An Anonim Şirketi (A.Ş.) — translated as Joint Stock Company or Anonymous Company — is a corporate structure governed by the Turkish Commercial Code (TTK Law No. 6102, Articles 329–563). It is the most sophisticated and flexible company type under Turkish law, and the preferred structure for larger enterprises, institutional investors, and businesses with complex capital requirements.

Unlike the Ltd. Şti., which limits shareholders to 50 and restricts share transfers, the A.Ş. places no limit on the number of shareholders (TTK Art. 338) and allows shares to be freely transferred — making it suitable for attracting external investment, issuing shares to employees, and eventually listing on a public market.

For foreign investors, the A.Ş. is fully accessible under DYYK (Law No. 4875) Art. 3/a, which guarantees that foreign nationals may establish or participate in Turkish companies on equal terms with domestic investors (the milli muamele — national treatment — principle). This applies to both natural persons and corporate foreign investors.

Key distinction

The A.Ş. is the only company type in Turkey that can make a public offering of shares. All companies listed on Borsa İstanbul are Joint Stock Companies.

Share capital and types of shares

The minimum share capital for an A.Ş. is ₺250,000 (TTK Art. 332). Of this, at least 25% (₺62,500) must be deposited into a designated bank account before Trade Registry registration (TTK Art. 344/1). The remaining 75% must be paid in full within 24 months of registration.

The A.Ş. structure allows considerable flexibility in how shares are structured:

  • Bearer shares (hamiline yazılı hisse) — ownership is determined by physical possession of the certificate. Transferable without formality, though subject to Central Registry Agency (MKK) recording requirements.
  • Registered shares (nama yazılı hisse) — ownership is recorded in the share ledger. Transfer restrictions can be imposed in the Articles.
  • Preference shares — shares carrying preferential rights to dividends, voting, or assets upon liquidation. Useful for structuring investor rounds.
  • Convertible instruments — the A.Ş. can issue bonds and other debt instruments convertible into equity, subject to general assembly approval.
Capital markets note

A.Ş. companies intending to make a public offering or list on Borsa İstanbul must additionally comply with Capital Markets Board (Sermaye Piyasası Kurulu — SPK) regulations, which impose additional disclosure, governance, and audit requirements.

Board of Directors

The A.Ş. is managed by a Board of Directors (Yönetim Kurulu). Under the 2012 revision of the Turkish Commercial Code, the minimum board size was reduced to one member — a significant simplification that makes the A.Ş. more accessible for smaller enterprises.

Board members may be shareholders or third parties, and may be natural persons or legal entities (though legal entity board members must designate a natural person to act as representative). At least one board member must have Turkish residency for certain regulated activities.

The board is responsible for the management and representation of the company. Day-to-day management may be delegated to an executive director (murahhas üye) or an external management team, provided the delegation is reflected in the Articles of Association and registered with the Trade Registry.

General Assembly

The General Assembly (Genel Kurul) is the supreme governing body of the A.Ş., comprising all shareholders. It must meet at least once per year for the ordinary general assembly (olağan genel kurul) to approve annual financial statements and dividend distribution. Extraordinary general assemblies (olağanüstü genel kurul) can be called at any time for matters such as capital increases, amendments to the Articles, or board changes.

Liability

Shareholders of an A.Ş. enjoy full limited liability — they are not personally liable for the company's debts beyond the value of their shares. Crucially, unlike Ltd. Şti. shareholders, A.Ş. shareholders are generally not subject to secondary liability for unpaid public debts (taxes, social security premiums). This is a meaningful advantage for companies in sectors with significant regulatory obligations.

Board members, however, have personal liability to shareholders and creditors for losses arising from their breach of duty. The 2012 TCC strengthened these director liability provisions significantly.

Auditing requirements

The A.Ş. has more rigorous financial reporting and audit requirements than the Ltd. Şti.:

  • Companies meeting certain thresholds (balance sheet total, net revenue, or number of employees) are required to undergo independent audit (bağımsız denetim) by a licensed audit firm.
  • Publicly held A.Ş. companies are subject to continuous SPK oversight and must publish audited financial statements quarterly and annually.
  • All A.Ş. companies must prepare annual financial statements in accordance with TFRS (Turkish Financial Reporting Standards) or relevant simplified standards.

Formation process overview

Forming an A.Ş. follows a similar path to the Ltd. Şti. but with additional steps reflecting its greater structural complexity. All registrations are processed through MERSİS (Merkezi Sicil Kayıt Sistemi), Turkey's centralized online Trade Registry system. Foreign shareholders must obtain a Turkish tax number (vergi kimlik numarası) before they can be entered into MERSİS.

  1. Company name reservation — uniqueness check with the Trade Registry under TTK naming rules.
  2. Articles of Association drafting — more detailed than the Ltd. Şti., specifying share classes, board structure, transfer restrictions, and authorized capital (if applicable). Notarized and bilingual. Mandatory clauses governed by TTK Art. 339.
  3. Capital deposit — at least 25% of the minimum ₺250,000 (₺62,500) deposited before registration per TTK Art. 344/1. Bank issues a confirmation letter for the Trade Registry.
  4. Trade Registry filing via MERSİS — electronic submission of all documents to the Ticaret Sicil Müdürlüğü. Registration typically takes 1 business day after submission.
  5. Gazette publication — the formation is published in the Turkish Trade Registry Gazette (Türkiye Ticaret Sicili Gazetesi — TTSG). This is a mandatory formal requirement for all A.Ş. formations.
  6. Tax, SGK, and Chamber registration — automatic triggers following Trade Registry registration.

Ongoing obligations

The A.Ş. has more extensive ongoing compliance obligations than the Ltd. Şti.:

  • Annual general assembly — must be held within 3 months of the fiscal year end. Minutes must be recorded and filed with the Trade Registry.
  • Financial statements — prepared and approved annually. Subject to audit if applicable thresholds are met.
  • Board resolutions — all material board decisions must be formally recorded and maintained in the board minutes book.
  • Share ledger maintenance — registered shares must be accurately tracked, and transfers recorded promptly.
  • MKK registration — bearer shares must be registered with the Central Registry Agency (Merkezi Kayıt Kuruluşu — MKK), regardless of whether the company is listed.
  • Trade Registry updates — changes to board composition, Articles, capital, or registered address must be filed promptly.

Foreign investors: rights and considerations

The A.Ş. is frequently the preferred vehicle for large foreign direct investments in Turkey. Under DYYK (Law No. 4875), foreign investors who hold at least 10% of shares in a Turkish company are classified as direct foreign investors and benefit from treaty-level protections. Key protections applicable to foreign shareholders of an A.Ş.:

  • Free transfer of dividends and proceeds (DYYK Art. 3/c) — profits, dividends, and sale proceeds may be transferred abroad freely through Turkish banks or authorized financial institutions.
  • Expropriation protection (DYYK Art. 3/b) — investment cannot be nationalized or expropriated except for public interest, under due process, on a non-discriminatory basis, with fair and timely compensation.
  • International arbitration access (DYYK Art. 3/e) — investment disputes may be referred to ICSID (International Centre for Settlement of Investment Disputes) or other international arbitral bodies agreed upon in investment contracts.
  • MIGA coverage — Turkey's MIGA membership allows eligible foreign investors to obtain insurance against non-commercial risks including currency transfer restrictions, expropriation, contract breach by government entities, and war/civil disturbance.
Foreign corporate investor documents

A foreign company acquiring shares in a Turkish A.Ş. must provide apostilled corporate documents: a Certificate of Incorporation (faaliyet belgesi) dated within 6 months, a Trade Registry excerpt (sicil özeti) showing directors and ownership structure, an apostilled power of attorney (vekaletname), and a board resolution authorizing the investment. All documents must be accompanied by certified Turkish translations.

When to choose an A.Ş.

Despite its higher capital requirement and greater compliance overhead, the A.Ş. is the right choice in several scenarios:

  • Multinational subsidiaries — large foreign groups often prefer the A.Ş. for its structural familiarity and cleaner shareholder liability profile.
  • Investment vehicles — funds and holding companies benefit from flexible share structure and unlimited shareholder capacity.
  • Businesses raising capital — preferred shares and convertible instruments make the A.Ş. the natural choice for startups planning equity rounds.
  • Employee equity plans — stock option and share purchase programs are more cleanly implemented in an A.Ş. structure.
  • Future IPO candidates — any company with a realistic path to public listing must be structured as an A.Ş. from the outset.
  • Regulated industries — banking, insurance, and capital markets activities require the A.Ş. structure by law.

Not sure which structure is right?

Most businesses — including the majority of foreign-owned subsidiaries in Turkey — are better served by the Ltd. Şti. The A.Ş. makes sense when you have specific capital-raising, governance, or regulatory requirements. We can help you decide based on your specific situation.
