In Q2'26, Micron Technology's (MU) total operating expenses reached $1.59B USD, with R&D expenses at $1.25B USD and SG&A expenses at $344M USD, marking a sequential increase driven primarily by elevated R&D investments. Over the period from Q3'23 to Q2'26, operating expenses exhibited a clear upward trend, rising from $977M USD to $1.59B USD, fueled by consistent growth in R&D from $758M USD to $1.25B USD amid semiconductor innovation demands, while SG&A remained relatively stable, fluctuating between $219M USD and $344M USD with modest annual gains. Key inflection points include a sharp R&D surge starting in Q1'24, contributing to overall volatility in earlier quarters before stabilizing into steady expansion, highlighting cost pressures in a competitive tech landscape.
