Commentary

Managing Director and Group CEO, Dr. Christian Behrenbruch, commented on the result:

“Telix continues to deliver strong revenue growth while building a foundation for the future. The first half of 2025 was a period of rapid transformation as we expanded our global manufacturing operations, invested in launching new products in new markets, and accelerated the development of our therapeutic pipeline. These investments have positioned Telix for sustainable, long-term growth, while our diversified business provides multiple drivers of success. To generate future revenue growth, we are confident in securing product approvals for Pixclara and Zircaix while advancing geographic and indication expansion for the PSMA portfolio.”
