Watch

Capital Expenditure Increase

Capital expenditure rose compared to both the prior quarter and the same quarter last year, outpacing the growth in operating cash flow. This was the strongest observable driver of the sequential decline in free cash flow and margin.

Higher capital expenditure absorbed a larger share of operating cash flow, reducing free cash flow and compressing the free cash flow margin.

What the cash flow says

How to interpret the company's free cash flow beyond the headline number.

Operating cash flow as a proportion of revenue weakened from the prior quarter but improved versus the same quarter last year. The free cash flow margin narrowed sequentially due to higher capital expenditure relative to operating cash flow, yet it was slightly lower than the year-ago margin.

Compared to the prior quarter, operating cash flow was lower and capital expenditure was higher, resulting in a lower free cash flow and a weakened margin. Versus the same quarter one year earlier, revenue, operating cash flow, capital expenditure, and free cash flow were all higher, while the free cash flow margin was slightly lower.

Monitor the trend in capital expenditure relative to operating cash flow, as the sequential increase in capex was the primary factor behind the decline in free cash flow margin.
