Autolus 2Q25 confirms the strong Aucatzyl US launch, EU launch put on hold

Yesterday before US market open, Autolus reported 2Q25 Aucatzyl sales of $20.9m, coming in above expectations (CSS: $13.4m). 1H25 sales of $29.9m implies 66 infused patients (i.e. approx. 6% market share), and points to a stronger than anticipated launch, which means our KBCS FY25 sales estimate of $43m is looking on the low end. Despite the strong US performance, the stock took a hit, likely due to the EU launch being put on hold, though we think this could protect the US business from an MFN perspective until there is more clarity. We reiterate our $10 TP and Buy rating.
