Melbourne (Australia) and Indianapolis, IN (U.S.) – April 14, 2026. Telix Pharmaceuticals Limited (ASX: TLX, NASDAQ: TLX) (“Telix”) today launches an offering of US$550 million convertible notes due 2031 to be issued by its wholly-owned subsidiary, Telix Pharmaceuticals (Investments) Inc. (the “Issuer”), and guaranteed by Telix and Telix Pharmaceuticals (US) Inc. (the “Offering”). The convertible notes, also referred to as “convertible bonds” (“Convertible Bonds”), are convertible into fully paid ordinary shares in Telix (“Ordinary Shares”).

Managing Director and Group CEO, Dr. Christian Behrenbruch, said: “The refinance of the existing Convertible Bonds represents our proactive approach to capital management. The new Convertible Bonds will continue to provide the business with cost effective financing.”

The new Convertible Bonds represent attractive, low-cost financing to Telix and are non-dilutive until any potential future conversions occur. The initial conversion price will be at a premium to Telix’s current share price.

After deduction of commissions, professional fees and other administrative expenses, it is intended that the net proceeds will be used to repurchase the existing convertible bonds due 2029 (“Existing Convertible Bonds”). Any funds raised above that required for the repurchase of the Existing Convertible Bonds will be applied to general corporate purposes.

Convertible Bonds Offering

Stock Borrow Facility

To assist the implementation of the Convertible Bonds Offering, Elk River Holdings Pty Ltd as the trustee for The Behrenbruch Family Trust¹ (“Stock Lender”) intends to enter into a stock lending agreement with an affiliate of J.P. Morgan (“Stock Borrower”) pursuant to which the Stock Lender will lend a certain number of Ordinary Shares to the Stock Borrower, and the Stock Borrower will be required to return the borrowed Ordinary Shares to the Stock Lender pursuant to the terms of the agreement (“Stock Borrow Facility”).

Concurrent Repurchase

Additionally, Telix is conducting a reverse bookbuilding process to receive indications of interest from holders of the Existing Convertible Bonds on a repurchase of the outstanding Existing Convertible Bonds (“Concurrent Repurchase”). The number of Existing Convertible Bonds to be repurchased and the purchase price will be determined by the reverse bookbuilding process.

Adviser

J.P. Morgan Securities plc (“J.P. Morgan”) is Sole Bookrunner on the Offering and Sole Dealer Manager on the Concurrent Repurchase.
