What the margin says

Filing-constrained interpretation of margin direction, comparisons, and what to monitor next.

Gross margin weakened from the prior quarter as cost of revenue fell less proportionally than revenue. Compared to a year ago, gross margin strengthened, with gross profit growing faster than cost of revenue relative to revenue.

Sequentially, revenue and gross profit were lower, and gross margin declined. Year-over-year, revenue and gross profit were higher, and gross margin improved.

Monitor the relationship between revenue and cost of revenue changes, as the sequential margin decline was driven by a proportionally smaller reduction in costs.
