As previously announced on the Public Disclosure Platform on April 11, 2025, our Company has signed the contract for the "Construction of Additional Units for the Wastewater Treatment Plant (3)" tender, held by the İstanbul Su ve Kanalizasyon İdaresi Genel Müdürlüğü (İSKİ), which represents a significant development in line with our vision to contribute to Turkey's infrastructure investments. We submitted the most advantageous bid with a contract value of TRY 2,500,000,000.00 and were awarded the project. The contract has been officially signed as of today.

This project is of great importance in terms of increasing İstanbul's wastewater treatment capacity in response to the city's growing population and urbanization dynamics, protecting environmental health, and implementing sustainable infrastructure solutions.

As Kontrolmatik, we aim to successfully complete this strategically important project by leveraging our engineering expertise in water technologies, technology-driven approach, and project management capabilities. While continuing to play an active role in infrastructure projects that deliver environmental sustainability and social benefit, we remain committed to creating long-term value for our investors.

This material event disclosure has been prepared in both Turkish and English. In case of any discrepancy between the two versions, the Turkish version shall prevail.

Respectfully announced to the public.
