Strong Operating Cash Flow

Operating cash flow increased compared to both the prior quarter and the year-ago quarter. This was the primary factor supporting free cash flow improvement, as free cash flow also rose versus both periods.

The higher operating cash flow drove free cash flow and free cash flow margin higher despite a year-over-year increase in capital expenditure.
