(1) Introduction and Background
On April 2, 2026, the Turkish Competition Authority (“Authority”) published the Turkish Competition Board’s (“Board”) reasoned decision concerning its investigation into Carrefoursa Carrefour Sabancı Ticaret Merkezi AŞ (“CarrefourSA”) and Yeni Mağazacılık AŞ (“A101”) regarding allegations that the undertakings had infringed Article 4 of Law No. 4054 on the Protection of Competition (“Law No. 4054”) through concerted practices involving parallel pricing (“Decision”).1 The investigation originated from a series of consumer complaints submitted from late 2023 onwards, which pointed to identical or closely aligned prices for products such as eggs, yoghurt, rice, butter and wafers across several national grocery retailers. The complaints also alleged that price increases were frequently implemented on the same or nearby dates.
