Explore Ameren Corporation (AEE) free cash flow from 2023 through the latest reported quarter, with SEC-sourced operating cash flow, capital expenditures, and period-by-period analysis.

Free cash flow takeaway

A quick read on the company's cash generation and what it means for investors.

For the quarter, revenue was higher than both the prior quarter and the year-ago period, while operating cash flow declined from the prior quarter but stayed near the year-ago level. Free cash flow became further negative due to a substantial increase in capital expenditure, resulting in a much weaker margin.

  • Revenue increased, but operating cash flow did not keep pace, falling from the prior quarter. The conversion of revenue into cash from operations weakened, and after significant capital spending, free cash flow turned deeply negative.
  • Compared to the previous quarter, revenue improved, operating cash flow decreased, capital expenditure rose, and free cash flow worsened. Relative to the same quarter last year, revenue was slightly higher, operating cash flow was similar, capital expenditure was higher, and free cash flow was more negative.

Recent events shaping cash flow

Near-term business events that help explain the free cash flow result.

Watch

Capital Expenditure Increase

Capital expenditure rose substantially compared to both the prior quarter and the year-ago period, outpacing the growth in revenue and operating cash flow.

The elevated capital spending was the main cause of the weakened free cash flow position.

What the cash flow says

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

Revenue increased, but operating cash flow did not keep pace, falling from the prior quarter. The conversion of revenue into cash from operations weakened, and after significant capital spending, free cash flow turned deeply negative.

Compared to the previous quarter, revenue improved, operating cash flow decreased, capital expenditure rose, and free cash flow worsened. Relative to the same quarter last year, revenue was slightly higher, operating cash flow was similar, capital expenditure was higher, and free cash flow was more negative.

Monitor the level of capital expenditure relative to operating cash flow, as the current quarter's elevated spending was the primary factor behind the negative free cash flow.
