Gross margin takeaway
Quarter ended Mar 31, 2026 · FY2026 Q3
Revenue and gross profit both increased compared to the prior quarter and the same quarter last year, while cost of revenue was stable relative to the prior quarter and higher year over year. Gross margin weakened slightly from both the prior quarter and the year-ago quarter, indicating that cost growth outpaced revenue growth on a relative basis.
- The strongest observable margin driver is the relationship between revenue and cost of revenue: revenue grew while cost of revenue remained unchanged sequentially, yet gross margin still declined, implying a shift in revenue composition or cost structure. The year-over-year comparison shows cost of revenue increased at a pace that outpaced revenue growth, compressing margin.
- Compared to the immediately preceding quarter, revenue and gross profit were higher, cost of revenue was stable, and gross margin was slightly lower. Compared to the same quarter one year earlier, revenue, gross profit, and cost of revenue were all higher, while gross margin was lower.

What the margin says
Filing-constrained interpretation of margin direction, comparisons, and what to monitor next.
The strongest observable margin driver is the relationship between revenue and cost of revenue: revenue grew while cost of revenue remained unchanged sequentially, yet gross margin still declined, implying a shift in revenue composition or cost structure. The year-over-year comparison shows cost of revenue increased at a pace that outpaced revenue growth, compressing margin.
Compared to the immediately preceding quarter, revenue and gross profit were higher, cost of revenue was stable, and gross margin was slightly lower. Compared to the same quarter one year earlier, revenue, gross profit, and cost of revenue were all higher, while gross margin was lower.
Monitor the trajectory of cost of revenue relative to revenue, as its stable sequential level combined with a margin decline suggests potential pressure from revenue mix or fixed cost absorption.
