In Q1'26, AVGO's total operating expenses reached $3.98B USD, with R&D expenses at $2.97B USD and SG&A expenses at $1.02B USD, reflecting a slight quarterly decline of 0.6% from Q4'25's $4.00B USD total, primarily driven by a modest drop in R&D spending. From Q2'23 to Q1'26, operating expenses exhibited a sharp upward trajectory, surging from $1.75B USD to $3.98B USD, fueled by a dramatic 67% jump in R&D expenses in Q1'24 to $2.31B USD—likely tied to increased innovation investments—and subsequent growth to a peak of $3.05B USD in Q3'25, while SG&A expenses stabilized around $1.0B-$1.1B USD after an initial spike to $1.57B USD in Q1'24; this overall 127% increase highlights escalating cost pressures amid expansion, with R&D consistently dominating as the larger component in the stacked bar chart.
