What the margin says

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

Gross margin weakened sequentially as cost of revenue grew faster than revenue, compressing the spread between revenue and cost of revenue. The year-over-year improvement in gross margin was driven by a larger increase in revenue relative to cost of revenue.

Compared to the immediately preceding quarter, gross margin was lower, with revenue unchanged and cost of revenue higher. Compared to the same quarter one year earlier, gross margin was higher, with both revenue and cost of revenue higher, but revenue increased more than cost of revenue.

Monitor the trajectory of cost of revenue relative to revenue, as a slight increase in cost of revenue with flat revenue led to a sequential gross margin decline.
