Telix Pharmaceuticals (ASX:TLX) Valuation After ZIRCON-X Data Highlights TLX250-CDx’s Potential Clinical and Commercial Impact

Telix Pharmaceuticals (ASX:TLX) just released ZIRCON-X study data showing its TLX250-CDx kidney imaging agent could have changed clinical decisions for almost half of patients, with more than 20% potentially avoiding invasive biopsy.

See our latest analysis for Telix Pharmaceuticals.

Despite the latest ZIRCON-X update highlighting the potential commercial impact of TLX250-CDx, Telix’s recent share price performance has been choppy, with a 1 month share price return of minus 9.68 percent and a resilient 3 year total shareholder return of 105.47 percent suggesting longer term momentum remains intact.

If this kind of clinical inflection point has your attention, it could be worth exploring other interesting healthcare stocks that might be setting up for their own rerating.

With the share price down sharply this year despite strong multi year returns and Telix trading at a steep discount to analyst targets, is this a mispriced growth story, or is the market already discounting everything ahead?

Price-to-Sales of 4.8x: Is it justified?

On a price-to-sales ratio of 4.8x versus a last close of A$14.28, Telix screens as clearly undervalued relative to peers and its own fair range.

The price-to-sales multiple compares the company’s market value to its revenue, which can be especially useful for high growth or earlier stage biopharma where earnings can be distorted by investment and one off items.

For Telix, trading at 4.8x sales while peers in the Australian Biotechs space sit around 15.3x suggests the market is heavily discounting its revenue base, despite forecasts for earnings to grow strongly and profitability to improve over time. Relative to an estimated fair price-to-sales ratio of 5.9x, there is also room for the market multiple to expand toward a level more in line with what its fundamentals might warrant if execution continues.

Against a peer average multiple of 20.6x, Telix’s 4.8x stands out as deeply conservative, implying investors are assigning it a substantial discount compared to similar biotech names despite its commercial stage assets and pipeline.

Result: Price-to-Sales of 4.8x (UNDERVALUED)

However, Telix remains vulnerable to clinical trial setbacks and regulatory delays, while recent share price volatility hints at shifting risk appetite for growth biotech names.
