MELBOURNE,Australia,July 19,2023 --Telix Pharmaceuticals Limited (ASX: TLX,Telix,the Company) today issues its Appendix 4C quarterly cash flow report and accompanying Activities Report for the quarter ended 30 June 2023 (Q2 2023). All figures are inAUD$ unless otherwise stated[1] and provided on an unaudited basis.

Summary

Total revenue up 21% quarter-on-quarter to $120.7M driven by global product sales

Positive operating cash flow ($10.8M,an improvement of $8.4M on the prior quarter)

Cash receipts from customers were $112.2M (up 35% from $83.2M in the prior quarter)

Closing cash balance of $131.7M (compared to $121.4M at prior quarter end)

Managing Director and Group CEO,Dr ChristianBehrenbruch commented,"Q2 2023 was another strong quarter for Telix,characterised by the ongoing trend of double-digit revenue growth from sales ofIlluccix® and continued positive operating cash flow. This is reflective of our excellent commercial performance and strength in PSMA-PETimaging[2]inall of Telix's operating markets.

"Simultaneously we are focused on the marketing authorisation of two further products for kidney and brain cancer imaging. Following successful planning meetings with the United States Food and Drug Administration (FDA),we are focused on preparing regulatory marketing applications,scaling up manufacturing and preparing for future product approvals and launch. Momentum also continues to build with our therapeutic pipeline,with clear clinical progress deliveredacrossourprostate,kidneyandglioblastoma programs. This activity is reflected in our investment in research and development (R&D),which remains in line with our stated plan."

During the quarterTelix opened its manufacturing site in Brussels South,[3] and announced two modest acquisitions. These strategic initiatives broaden the late-stage pipeline and further enhance Telix's position as a vertically-integrated radiopharmaceutical company to support a breadth of future product offerings across the continuum of patient care.

"Our depth and commitment to urologic oncology starts with Illuccix and,with the agreement to acquire Lightpoint Medical,[4] now continues into surgical intervention. We have also added to our artificial intelligence (AI) capability through the acquisition of Dedicaid GmbH,[5] which brings with it a dedicated team of scientists to bridge reader and clinical decision support,and eventually disease prediction.

"Finally,theinaugurationofourEuropean radiopharmaceuticalproductionfacility –Telix Manufacturing Solutions – represents a significant milestone for the Company and a vital step towards building the foundation for long-term,commercial success and delivering to the needs of patients," added DrBehrenbruch.

Clinical Programs Update

The Company has over 20 clinical studies underway,including Telix-sponsored and collaborative investigator-initiated trials.

Duringthequarter,notableupdateswerepublishedonthenewssectionoftheCompany'swebsite (www.telixpharma.com/news-views) and are summarised in this section of the Activities Report.

Priority focus areas for the clinical pipeline:

Preparation of a Biologics License Application (BLA) and commercialisation of TLX250-CDx (89Zr-DFO- girentuximab),Telix'sinvestigationalkidneycancerimaging agent: As supported under the Breakthrough Therapy designation,the Company is actively engaging with the FDA as it prepares its regulatory filing. The Company participated in a Type B meeting with the agency duringthe quarter. Based on this positive discussion the Company continues to progress its BLA submission in 2023 as planned.

Telix is in the process of implementing an Expanded Access Program (EAP) in the U.S. and providing compassionate use access in the rest of world,to provide TLX250-CDx to patients and physicians in areas of unmet need,prior to obtaining marketing authorisation. During the quarter the first sites and requests were on-boarded and fulfilled. The Company is also conducting new research and clinical studies to explore the theranostic utility of this investigational asset in other cancers expressing carbonic anhydraseIX(CAIX),where there are currently high unmet medical needs.

Preparation of a New Drug Application (NDA) for TLX101-CDx (18F-FET),Telix's investigational brain cancer imagingagent: TheCompany continuestoprogress itsregulatoryfilingwiththeFDAforsubmissionduring2023,in preparation for U.S. commercial launch in 2024,pending regulatory approval.

Pipeline Expansion and Advanced Manufacturing Highlights

Urologic product offering enhanced with two acquisitions

Telix is building on its differentiated offering for the field of urologic oncology with the announcement of two acquisitions during the quarter – Lightpoint Medical (Lightpoint) and Dedicaid GmbH (Dedicaid) – which accelerate the Company'slate-stagedevelopmentprogramsinsurgical technologyandAI,respectively.Bothofthesetechnologiesare complementary to the Company's existing product and research pipeline,further enhancing Telix's innovation positionandproductdepthfortheurologycustomer andpatient.TheLightpoint acquisitionagreementissubject tocompletionof agreed closing conditions.

Lightpoint's SENSEI® device is an ultra-miniature robotic gamma probe for intra-cavital use that is able to provide radiopharmaceutical-basedsurgicalguidance (radio-guidedsurgery)byenablingtheintra-operativedetectionofcancer in real-time. Telix's initial commercial objective is to align SENSEI with Telix's Illuccix and TLX599-CDx (99ᵐTc-HYNIC- iPSMA) programs for prostate cancer. Additionally,there is considerable scope to expand into other urologic and non- urologic malignancies. Lightpoint also has innovative capabilities in AI for surgical guidance that will complement Telix's AI program. SENSEI has been approved by the FDA and has attained a Conformité Européenne (CE) Mark in Europe for intra-operative detection of sentinel lymph nodes and cancer metastasis via the lymphatic system,and is currently the only gamma probe validated for use with the Intuitive Surgical DaVinci® robotics system.[18]

TheacquisitionofDedicaidexpands Telix'sAIoffering,withtheaddition ofaclinicaldecisionsupport softwareplatform designed to predict outcomes such as the severity of disease,risk to the patient and/or inform treatment decisions.

The Dedicaid AI platform is also favourably differentiated from commercially-available AI solutions currently used in PSMA-PET imaging,which are limited to supporting clinicians in the interpretation and reading of images – without a prediction capability.
