In Q1'26, both R&D and SG&A expenses for SOUN show no data, resulting in total operating expenses of $0 USD, a significant departure from prior quarters where costs were substantial. From Q2'23 to Q4'25, SOUN's operating expenses exhibited a strong upward trend, rising from $23.2M USD in Q2'23 to a peak of $63.5M USD in Q3'25, driven by accelerating R&D costs (from $11.7M USD to $22.8M USD) and particularly sharp growth in SG&A (from $11.5M USD to $40.7M USD), reflecting expansion in sales, marketing, and administrative functions; however, a slight moderation occurred in Q4'25 with total expenses at $63.5M USD, before the absence of data in Q1'26.
