    Before this approval, the most bearish analysts were modeling about US$535.0 million of revenue and only US$22.0 million of earnings by 2029, so compared with the view that VIKTORIA 1 success and broad oncologist adoption could transform Celcuity’s prospects, you can see how far apart opinions were and why this new data and approval may lead both camps to revisit their assumptions.
