With its clinker production, cement grinding capacity, and market share, OYAK Cement continued to be the largest player in Türkiye’s cement industry in 2024. Five publicly listed cement companies within OYAK Cement Concrete Paper—Adana Çimento, Bolu Çimento, Ünye Çimento, Aslan Çimento, and Mardin Çimento—were merged under Mardin Çimento Sanayii ve Ticaret A.Ş. on May 15, 2020 to ensure more efficient management, establish a strong financial, administrative, and legal structure, and strengthen production and distribution activities. Following the merger, the company’s name was changed to OYAK Çimento Fabrikaları A.Ş.
