What Is Merger Control?
Merger control refers to the regulatory process by which competition authorities review mergers, acquisitions, or joint ventures to ensure that such transactions do not harm market competition.
In Turkey, merger control is preventive in nature — it aims to avoid market dominance or anti-competitive concentration before it occurs, rather than penalizing it afterward.
This system ensures that structural changes in the market, such as consolidations or takeovers, do not create or strengthen a dominant position that could restrict competition or harm consumers.
Legal Framework and Competent Authority
Merger control in Turkey is primarily governed by:
- Law No. 4054 on the Protection of Competition, and
- Communiqué No. 2010/4 on Mergers and Acquisitions Requiring the Approval of the Competition Board (amended by Communiqués No. 2017/2 and No. 2022/2).
The Turkish Competition Authority (TCA), an independent administrative body, enforces these provisions.
The Competition Board — the decision-making body within the TCA — is responsible for:
- assessing merger and acquisition notifications,
- approving or prohibiting transactions, and
- imposing remedies or fines if necessary.
Which Transactions Are Subject to Merger Control?
According to Article 5 of Communiqué No. 2010/4, the following transactions must be notified to the TCA if they result in a change of control on a lasting basis:
- Mergers between two or more undertakings; or
- Acquisitions of direct or indirect control over all or part of one or more undertakings by another undertaking or person that already controls at least one undertaking.
Control can be acquired through:
- purchase of shares or assets,
- contractual arrangements (e.g., voting rights, management agreements), or
- any other means conferring decisive influence.
Both domestic and foreign-to-foreign transactions can fall under Turkish merger control if the turnover thresholds are met.
Why Is Merger Control Important for Businesses?
Compliance with Turkish merger control obligations provides several benefits:
- Legal certainty for closing transactions,
- Avoidance of financial penalties and administrative delays,
- Enhanced credibility and transparency with regulators,
- Protection from future challenges by competitors or public authorities.
Especially in high-growth sectors such as technology, health, and finance, understanding these rules is essential to execute M&A transactions efficiently and lawfully.
