In Q4'26, CRWD's total operating expenses reached $979.89M USD, with R&D expenses at $356.41M USD and SG&A expenses at $623.48M USD, reflecting a slight quarterly increase from Q3'26's $995.88M USD total driven by modest R&D growth offset by a dip in SG&A. Over the period from Q1'24 to Q4'26, operating expenses exhibited a robust upward trend, expanding from $542.81M USD to nearly $980M USD, fueled by consistent increases in both R&D (from $179.07M USD to $356.41M USD, with acceleration post-Q4'24) and SG&A (from $363.74M USD to $623.48M USD, marked by a sharp 37% jump in Q3'25). SG&A consistently dominated the breakdown, comprising 65-75% of total expenses, while R&D showed steady growth averaging 15% quarterly, indicating scaling investments in innovation amid overall expense inflation. No significant declines occurred until a minor SG&A pullback in Q4'26, suggesting potential cost optimization.
