Additional Explanations

At the Ordinary General Assembly Meeting of our Company held on December 2, 2024, regarding the fiscal year 2023, the Share Buyback Program ("Program"), prepared in accordance with the relevant legislation, was approved and the Board of Directors was authorized to initiate share buyback transactions. Following the discussions, the Board of Directors resolved at its meeting dated May 13, 2025, to commence the share buyback within the scope of the aforementioned Program.

Under the Program, the maximum number of shares subject to buyback is 2,500,000, corresponding to 2.7% of the Company's share capital. If economic and commercial conditions, capital market circumstances, trading volumes on Borsa Istanbul, and/or the Company's financial standing are deemed unfavorable, the Board of Directors is fully authorized to terminate or suspend the Buyback Program prior to reaching the specified maximum number of shares.

In line with the resolution, on May 13, 2025, our Company repurchased ATATP shares with a total nominal value of TL 98,530 on Borsa Istanbul at a price range of TL 79.6 – TL 81.0 per share (weighted average price: TL 80.39).

The ratio of the repurchased shares to the Company's total capital is 0.1051%.
