Arbutus Biopharma and Genevant Sciences have launched new patent lawsuits targeting lipid nanoparticle technology used in Pfizer BioNTech (NasdaqGS:BNTX) COVID-19 vaccines. The actions seek monetary damages and potential injunctions across Canada and multiple European countries.

For investors, the latest lawsuits arrive after a weaker period for BioNTech’s stock, with the share price at US$92.95 and short term momentum softening following a 90 day share price return that declined 10.15%, while the 1 year total shareholder return is down 15.54%.

"Amputation, intoxication and radiation". If students read about our current cancer treatment in 2050, they would probably date it back to 1960-70. Certainly not dating back to the time of AI, fusion reactors or recurring missiles.

Another View On BioNTech’s Valuation

While the community narrative points to a fair value of $499.94 per BioNTech share, the current P/S ratio of 7.3x paints a different picture. It is higher than both the fair ratio of 5.3x and the peer average of 6.1x, which hints at valuation risk rather than a clear bargain. This raises the question of whether the market is paying a premium for future potential that may take time to materialize.
