As of Q4'25, IONQ’s P/E Ratio has turned positive for the first time in the observed period, reaching 5.15. This marks a significant shift from the previous quarter (Q3'25), which recorded a negative P/E Ratio of -13.39, indicating a notable improvement in the company’s earnings relative to its share price. From Q1'23 to Q3'25, the P/E Ratio remained negative, fluctuating between -26.4 and -8.88, reflecting ongoing losses. The ratio showed a general improving trend from Q2'23 (-25.29) to Q2'24 (-8.88), before experiencing renewed volatility and deeper negatives in late 2024 and early 2025. The sharp reversal to a positive P/E Ratio in Q4'25 suggests a potential turnaround in profitability, representing a critical inflection point in IONQ’s financial performance over this nearly three-year period.
