Gross margin takeaway

- Cost of revenue remained stable versus the prior quarter, while revenue declined, which compressed gross profit and margin. Compared to the year-ago quarter, cost of revenue increased at a faster pace than revenue, pressuring gross margin.
- Gross margin weakened sequentially and also declined compared to the same quarter last year. The sequential decline was driven by a larger drop in gross profit relative to revenue, while the year-over-year decline reflected cost of revenue growing faster than revenue.
