Lyft reported its first-ever profitable quarter, with CEO David Risher highlighting record rides, riders, and a 40% increase in revenue year-on-year. The company saw active riders grow by 10% to 23.7 million and rides increase by 17% to 205 million. Despite these achievements, Lyft's shares fell nearly 20% due to a weaker-than-expected earnings forecast, raising concerns about its competition with Uber. Lyft's total bookings missed expectations at $4.02 billion, and it anticipates similar results in the third quarter.
