In Q4'25, AMD's operating expenses reached a total of $3.53B USD, with R&D expenses at $2.33B USD and SG&A expenses at $1.20B USD, marking the highest quarterly figure in the observed period and reflecting accelerated investments in innovation and operations. From Q1'23 to Q4'25, total operating expenses exhibited a consistent upward trend, growing from $2.00B USD to $3.53B USD, driven primarily by R&D expenses which surged from $1.41B USD to $2.33B USD—a 65% increase—while SG&A expenses rose more steadily from $585M USD to $1.20B USD. This pattern highlights AMD's expanding focus on research and development amid competitive pressures in the semiconductor sector, with no significant declines or volatility observed across the 12-quarter timeframe.
