In Q1'26, IONQ's total operating expenses reached $243.8M USD, with R&D expenses at $125.7M USD and SG&A expenses at $118.1M USD, marking a significant escalation from prior quarters and reflecting intensified investment in research and administrative functions. From Q2'23 to Q1'26, operating expenses exhibited a strong upward trend, starting at $34.4M USD and climbing to $243.8M USD, driven by consistent growth in both R&D (from $19.9M USD to $125.7M USD) and SG&A (from $14.5M USD to $118.1M USD). Notable inflection points include sharp increases in Q4'24 (total $78.6M USD) and Q2'25 (total $162.3M USD), indicating accelerated spending possibly tied to expansion or operational scaling, with R&D maintaining a slight edge over SG&A throughout the period in a stacked bar visualization.
