Telix Pharmaceuticals Limited ACN 616 620 369 55 Flemington Road North Melbourne Victoria, 3051 Australia ASX ANNOUNCEMENT Page 1 FDA Accepts NDA for TLX101-Px (Pixclara®) Melbourne (Australia) and Indianapolis, IN (U.S.) – April 10, 2026. Telix Pharmaceuticals Limited (ASX: TLX, NASDAQ: TLX, “Telix”) today announces that the United States (U.S.) Food and Drug Administration (FDA) has accepted the Company’s resubmitted New Drug Application (NDA) for TLX101-Px1, (Pixclara®2, Floretyrosine F 18 or 18F-FET), an investigational PET3 agent for the imaging of glioma (brain cancer), and has assigned a PDUFA4 goal date of September 11, 2026. The approval of TLX101-Px will fulfil a significant unmet medical need for the characterization of recurrent or progressive glioma from treatment related changes in both adult and pediatric patients5. Neuroimaging of glioma with 18F-FET is already broadly recommended in international clinical practice guidelines – including NCCN Guidelines®6 – and TLX101-Px has been granted Orphan Drug7 and Fast Track8 designations by the FDA. “There remains a critical unmet need in improving our ability to image residual glioma after treatment,” said Thomas Hope, MD, Vice Chair, Department of Radiology and Biomedical Imaging, University of California, San Francisco (UCSF). “We have worked with Telix for the last three years to help leverage our clinical data to help make FET-PET9 available to patients in the United States.” Patrick Wen, MD, E. Antonio Chiocca, MD, PhD, Family Endowed Chair in Neuro-Oncology at Mass General Brigham Cancer Institute, added, “Distinguishing tumor progression from treatment-related change remains one of the most challenging aspects of glioma care. PET imaging with 18F-FET is an important tool in clinical practice worldwide, and the FDA’s acceptance of this application is a meaningful step toward broader access for patients and clinicians in the United States.” Kevin Richardson, CEO, Telix Precision Medicine, added, “The FDA’s acceptance of our NDA resubmission is an important milestone for Telix. We appreciate the FDA’s constructive engagement and look forward to working closely with the Agency to urgently obtain approval and then bring this product to market for the benefit of patients.” Telix’s FY 2026 financial guidance does not include any revenue contribution from TLX101-Px.

This enables TLX101-Px to be potentially utilized as a patient selection and response assessment tool for Telix’s LAT1-targeting therapy candidate TLX101-Tx (iodofalan 131I), currently under investigation in the pivotal IPAX-BrIGHT trial in patients with recurrent glioblastoma10 . TLX101-Px and TLX101-Tx have not received marketing authorizations in any jurisdiction. About gliomas Gliomas are diffusely infiltrative tumors that affect the surrounding brain tissue. They are the most common form of central nervous system (CNS) cancer that originates from glial cells, accounting for approximately 30% of all brain and CNS tumors and 80% of all malignant brain tumors11. In the U.S., there are approximately 24,000 new glioma cases diagnosed annually12. Glioblastoma (GBM) is a high-grade glioma and the most common and aggressive form of primary brain cancer. The mainstay of treatment for GBM comprises surgical resection, followed by combined radiotherapy and chemotherapy. Despite such treatment, recurrence occurs in almost all patients13, with an expected survival duration of 12-15 months from diagnosis14.
