Earnings Release

This bulletin has been prepared based on the inflation-adjusted financial statements of OYAK Cement Factories Inc. in accordance with the Turkish Accounting and Financial Reporting Standards (TFRS) and the requirements of the Capital Markets Board Decision dated December 28, 2023.

In the third quarter of 2025, OYAK Cement's consolidated revenues increased by 16% quarteron-quarter, reaching TRY 15.4 billion, supported by higher sales volumes despite limited price increases. While price adjustments remained below inflation and the strong base effect led to flat revenue performance in the first nine months of the year, export volumes rose by 21% year-onyear during the same period.

Cement and ready-mixed concrete (RMC) volumes recorded double-digit quarterly growth in the third quarter (10% and 14%, respectively). Backed by its robust market presence and a network of 60 concrete plants across seven regions of Türkiye, the Company achieved over 30% year-onyear growth in RMC volumes for two consecutive quarters (2Q25: +39%; 3Q25: +31%).

EBITDA increased by 57% in real terms compared to the previous quarter, while the EBITDA margin expanded by 8 percentage points, reaching 30.6% in the third quarter. For the first nine months of 2025, EBITDA amounted to TRY 10.9 billion, corresponding to a 26.8% margin.

The Company's net profit rose by 22% in real terms year-on-year to TRY 3.4 billion in the third quarter, bringing the total for the first nine months of 2025 to TRY 7.3 billion.

The solar power plant in Beypazarı (Ankara) is expected to commence partial operations by the end of 2025 and reach full capacity in the first quarter of 2026. Waste heat recovery projects at the Adana, Ankara, and Mardin plants are planned to be commissioned gradually throughout 2026.
