I have been reading Lyft S-1, especially their risk factor assessment. While it is full of normal warnings like limited operating history, competitors etc. One of the warnings stood out for me. Our results of operations vary and are unpredictable from period-to-period, which could cause the trading price of our Class A common stock to decline. If this is the case, I wonder how do they can they even predict their future growth? How much credence can be given to the data they present or expect about their growth?
