Gross margin takeaway
Quarter ended Mar 31, 2026 · FY2026 Q1
Revenue and gross profit both rose compared to both the prior quarter and the same quarter a year earlier. Gross margin weakened relative to the prior quarter but improved compared to the year-ago period.
- The gross profit increased more than proportionally relative to cost of revenue when compared with the same quarter last year, leading to an improved gross margin. However, the sequential increase in cost of revenue outpaced the revenue growth, causing the gross margin to weaken from the prior quarter.
- Compared with the prior quarter, revenue was higher and gross profit was higher, but gross margin was lower due to a larger relative increase in cost of revenue. Compared with the same quarter one year earlier, revenue, gross profit, and gross margin were all higher.
