Operating Cash Flow Decline

The most observable driver of the weaker free cash flow was the decrease in operating cash flow, which fell in both sequential and year-over-year comparisons. Capital expenditure increased, further pressuring free cash flow.

The free cash flow margin weakened as a result, declining from the prior quarter and from the year-ago quarter.
