Mergers and Acquisitions and the Notification Obligation within the Framework of Competition Law 19 October 2025
Mergers and acquisitions (M&A) are at the center of the growth and restructuring strategies of companies. These transactions, serving the purpose of companies to expand both nationally and internationally to increase their market shares or to enter into new markets, not only give rise to economic and commercial consequences but also carry the potential to directly affect the competition dynamics in the relevant market. Therefore, merger and acquisition transactions may affect the competition structure in the market. In this respect, while M&A transactions create strategic opportunities, they are also among the areas carefully scrutinized by regulatory authorities to preserve competitive order.

This article addresses the conditions governing mergers and acquisitions under Turkish competition law and the legal consequences of failing to comply with the notification requirement. |
1. M&A transactions within the Act on the Protection of Competition |
Pursuant to Article 7 of the Act on the Protection of Competition No. 4054 (the "Act"), |
|
|
The Competition Authority has regulated in secondary regulations which mergers and acquisitions are subject to the above obligations. |
2. Secondary Regulations |
The procedures and principles regarding the determination of mergers or acquisitions that are required to obtain authorization from the Competition Board (the "Board") in order to gain legal validity, and their notification to the Board, are regulated by the Communique No. 2010/4 on Mergers and Acquisitions Requiring Authorization from the Competition Board (the "Communique"). |
3. Cases Considered as Mergers and Acquisitions as per the Competition Law |
According to Article 5 of the Communique, in a manner to bring about a permanent change of control: |
|
|
Pursuant to Article 7 of the Communique, in the cases considered as mergers and acquisitions mentioned above, in order for the planned merger or acquisition transaction to gain legal validity, the requirement to obtain the authorization of the Board arises if certain turnover thresholds are exceeded. Accordingly: |
|
|
In transactions involving the acquisition of technology undertakings operating in the Turkish geographical market, having R&D activities or providing services to users in Turkiye, the 250 million TRY thresholds shall not apply. |
Cases Not Considered as Mergers and Acquisitions as per the Competition Law |
Pursuant to Article 6, for transactions listed below the authorization of the Board is not required: |
|
|
|
|
Before any explicit or implicit decision is rendered regarding notification made in respect of mergers or acquisitions subject to authorization, the merger or acquisition cannot gain legal validity. |
4. Failure to Notify |
In cases where mergers or acquisitions that are required to be notified are not notified to the Board or are notified after the transaction has been carried out, |
|
|
5. Evaluation of the Report |
In the assessment of mergers and acquisitions, in particular; the structure of the relevant market, the actual and potential competition of the undertakings established within or outside the country, the position of the undertakings in the market, their economic and financial powers, the alternatives to find suppliers and customers, the possibility of access to sources of supply, barriers to entry into the markets, supply and demand trends, the interests of consumers, efficiencies to the benefit of consumers, and other matters shall be taken into consideration. |
Mergers or acquisitions that result, by creating a dominant position or strengthening an existing dominant position, in a significant lessening of effective competition within the whole or part of the country is not permitted. |
6. Conclusion |
In conclusion, mergers and acquisitions are not only instruments of corporate growth and restructuring but also transactions that directly impact market competition. Therefore, in order to obtain legal validity, they must be notified to the Competition Board, and the required approvals must be secured. Failure to comply with this obligation may result in the invalidity of the transaction and the imposition of administrative fines, as well as the potential termination of anti-competitive transactions by the Board. |

The employee undertakes not to compete with the employer during the term of the employment contract as part of their loyalty obligation.
