As of Q4'25, UPST's P/E Ratio stands at 71.276, marking a significant turnaround from the previous quarter’s negative value. This latest data point reflects a return to positive territory after a prolonged period of negative P/E Ratios, with the most extreme low recorded at -1016.852 in Q2'25. From Q1'23 to Q2'25, the P/E Ratio exhibited a persistent downward trend, deepening into increasingly negative values and reaching its lowest point in Q2'25. However, Q3'25 saw a dramatic reversal, with the P/E Ratio surging to 139.662, followed by a stabilization at 71.276 in Q4'25. This sharp inflection suggests a major shift in UPST’s earnings outlook, possibly driven by a return to profitability or significant changes in market expectations.
