Executive Commentary

Dr. Christian Behrenbruch, Managing Director and Group CEO, stated, “Growth accelerated across

our Precision Medicine business in the first quarter, with U.S. dose volumes increasing 5% quarter-

over-quarter. This performance reflects the growing uptake of Gozellix alongside Illuccix,

contributing to market share gains underpinned by disciplined sales execution and pricing, and

high-quality service delivery despite extreme North American weather conditions, an advantage of

the pharmacy distribution model. With our two‑product PSMA9 imaging strategy, differentiated

clinical positioning and expanding commercial presence globally, we are seeing a solid foundation

for continued growth through 2026. Importantly, we are delivering on our strategic priorities to

advance our high-value clinical programs, demonstrated by the momentum in our therapeutics

pipeline this quarter."

Therapeutics Business Unit

Telix continues to progress its industry-leading Therapeutics pipeline, which spans multiple product

candidates and disease areas. Q1 2026 highlights include:

•TLX591-Tx (lutetium (177Lu) rosopatamab tetraxetan): Part 1 of ProstACT Global, the Phase

3 trial of its lead prostate cancer therapy candidate, achieved its study objectives,

demonstrating an acceptable safety and tolerability profile with no new safety signals

observed1. No adverse drug-drug interactions were observed in TLX591-Tx combinations,

demonstrating the feasibility of integrating TLX591-Tx with current standard of care therapies

for mCRPC10, including ARPIs11 (enzalutamide or abiraterone) and docetaxel. Telix has

commenced engagement with the FDA to present data from Part 1 and ascertain eligibility for

U.S. patients to participate in Part 2 (randomized treatment expansion). Part 2 is open for

enrollment in Australia, New Zealand and Canada, with site activation underway in preparation

to open enrollment in China, Singapore, South Korea, Türkiye, the United Kingdom and Japan,

where regulatory approvals have already been granted.

•TLX250-Tx (lutetium (177Lu) girentuximab tetraxetan): Telix has opened its first clinical site

and is recruiting patients for Part 1 of LUTEON12, a pivotal trial of TLX250-Tx as a

monotherapy in advanced ccRCC13. Trial recruitment will initially focus ex-U.S.

•TLX101-Tx (131I-iodofalan): Telix has enrolled the first patient in IPAX-BrIGHT, an international,

multi-center pivotal trial of TLX101-Tx in patients with recurrent glioblastoma14. The trial is now

open for enrollment in Australia, Austria and the Netherlands and has received regulatory

approval to commence in Belgium.

•TLX090-Tx (153Sm-DOTMP): Telix continues to dose patients in SOLACE15, a Phase 1 study of

a drug candidate for treating pain in patients with osteoblastic bone metastases from prostate

and breast cancers. The study was expanded this quarter to include additional U.S. sites to

accelerate recruitment.

•TLX597-Tx (177Lu-DOTA-HYNIC-panPSMA): TLX597-Tx is a "next generation" PSMA-

targeting prostate cancer therapy candidate being developed to facilitate patient access in

select geographies, where routine clinical availability to approved therapies is limited or not

available. Early clinical data suggests a favorable asset biodistribution with limited uptake in

healthy organs of concern (e.g., salivary glands, kidneys) relative to available 177Lu-PSMA

therapies. Interim data from OPTIMAL-PSMA16, an investigator-led, randomized, dose

intensification study of TLX597-Tx in mCRPC, will be presented at the International Prostate

Cancer Symposium in April 2026.

PSMA imaging portfolio:

•Telix continues to expand its commercial footprint with Illuccix now launched in 21 countries

globally, which includes 16 countries in Europe. This growing international presence enhances

access to PSMA-PET/CT imaging17 while establishing a scalable commercial and operational

platform to support future product launches, including follow-on therapeutic products.

•Telix's broad proposed label for TLX591-Px (Illuccix) is under review by the NMPA Centre for

Drug Evaluation as part of the NDA submission18.

TLX101-Px, (Floretyrosine F 18 or 18F-FET):

•Telix has resubmitted its NDA in the U.S. with the additional clinical data and analysis as

agreed with the FDA.

•Telix has submitted a MAA in Europe covering commercially significant markets, seeking to

expand patient access to advanced brain imaging.

Zircaix®3 (TLX250-Px, 89Zr-DFO-girentuximab):

•Based on two successful Type A meetings with the FDA, Telix believes it has aligned on key

outstanding issues for the Biologics License Application (BLA) resubmission, including

demonstration of drug product comparability between clinical trial material and scale-up

commercial production. The Company is now completing the agreed deliverables and

documentation required, targeting a H1 submission.

Corporate Updates

Telix has announced the appointment of David Gill as Non-Executive Director (NED), effective May

11, 2026, as part of its Board renewal process19. Mr. Gill is expected to be appointed as Chair in

U.S. public company governance, financial oversight and senior leadership across commercial and

clinical-stage biopharmaceutical companies.
