What has pushed the shares higher over the past 9 weeks?
After bottoming out in mid-February, Telix shares have rebounded following a flurry of consecutive good-news updates.
In late-February, the company confirmed that it had filed a key regulatory approval in Europe.
Later in March, Telix posted several announcements about its growth and development plans.
It released positive Part 1 results from its global Phase 3 ProstACT study of TLX591-Tx, its novel prostate cancer therapy in early-March.
The following week, Telix announced it had resubmitted its New Drug Application (NDA) to the U.S. FDA for TLX101-Px (Pixclara®), a brain cancer imaging candidate. Telix's resubmission includes new data addressing the US Food and Drug Administration (FDA)'s previous requests.
The good news continued on through April, too.
On the 10th of April, the company announced that the FDA has accepted its NDA for TLX101-Px (Pixclara®).
Just a few days later, Telix announced a major collaboration with US-based Regeneron Pharmaceuticals. The two companies entered a 50/50 global cost and profit-sharing agreement to co-develop radiopharmaceutical therapies targeting solid tumours.
Last week, the biopharma company released an investor presentation which revealed a 56% increase in group revenue and underlying profitability supported by a positive cash balance of US$142 million. Telix also issued FY26 revenue guidance in the range of US$950 million to US$970 million.
The company has also priced and increased its US$600 million convertible bond offering, up from US$550 million due to strong global investor demand.
The flurry of good news has caused a positive swing of sentiment and it looks like many are now buying back into the biopharmaceutical's shares while they are trading for cheap.
