Gross margin takeaway
Quarter ended Sep 30, 2025 · FY2025 Q3
Revenue increased slightly from both the prior quarter and the same quarter last year, while cost of revenue held steady relative to the previous quarter and edged higher year-over-year. Gross profit rose in both comparisons, and gross margin improved sequentially and showed a larger improvement versus the prior year.
- Gross margin strengthened compared with both the preceding quarter and the same quarter one year earlier, driven primarily by revenue growing faster than cost of revenue. The strongest observable driver is the gross profit dollar growth, which outpaced the increase in revenue, indicating a favorable spread between revenue and cost.
- Sequentially, revenue rose slightly and cost remained unchanged, resulting in higher gross profit and an improved margin. Year-over-year, both revenue and cost increased, but the revenue gain was larger, leading to a higher gross profit and a stronger gross margin.

What the margin says
Filing-constrained interpretation of margin direction, comparisons, and what to monitor next.
Gross margin strengthened compared with both the preceding quarter and the same quarter one year earlier, driven primarily by revenue growing faster than cost of revenue. The strongest observable driver is the gross profit dollar growth, which outpaced the increase in revenue, indicating a favorable spread between revenue and cost.
Sequentially, revenue rose slightly and cost remained unchanged, resulting in higher gross profit and an improved margin. Year-over-year, both revenue and cost increased, but the revenue gain was larger, leading to a higher gross profit and a stronger gross margin.
Monitor the trajectory of cost of revenue given it was unchanged sequentially despite higher revenue, as any future cost increase could compress margin.
