The latest data point for RKLB's PEG Ratio in Q4'25 stands at -1.12, indicating a negative valuation metric that suggests the stock may be undervalued relative to its earnings growth, though the negative value reflects potential challenges in profitability or growth projections. This follows a volatile period, with the ratio fluctuating significantly across quarters. Over the timeframe from Q1'23 to Q4'25, the PEG Ratio exhibits high volatility, starting at -0.48 in Q1'23, spiking dramatically to 150.23 in Q2'23 before settling into a pattern of oscillation between positive peaks (e.g., 1.16 in Q1'24 and 1.99 in Q2'24) and deepening negatives (e.g., -8.32 in Q2'25). Notable inflection points include the sharp decline to -1.24 in Q3'24 and a brief recovery to 0.82 in Q3'25, underscoring inconsistent growth expectations; Q4'24 has no data, but the overall trend leans toward instability rather than sustained improvement or decline.
