In Q1'26, TEM's total operating expenses reached $258.1M USD, with SG&A Expenses at $212.6M USD comprising the majority (82%) and R&D Expenses at $45.9M USD making up the remainder, reflecting a significant drop from the prior quarter's elevated levels. From Q2'23 to Q1'26, operating expenses exhibited volatile growth, starting at $116.8M USD and surging to a peak of $609.0M USD in Q2'24 driven by spikes in both R&D (from $45.6M to $145.9M USD) and SG&A (from $71.2M to $463.1M USD), before stabilizing and climbing steadily to $298.7M USD in Q4'25; the sharp decline in Q1'26 suggests potential cost optimization or one-time factors, with SG&A consistently dominating the stack (averaging 70-80% of total) while R&D showed moderate upward trends outside the Q2'24 anomaly.
