Westinghouse Air Brake Technologies (WAB) Free Cash Flow & Quarterly History

Explore Westinghouse Air Brake Technologies Corporation (WAB) 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.

Free cash flow was stable compared to the year-ago quarter as operating cash flow and capital expenditure moved in line. However, it dropped sharply from the prior quarter, driven by a significantly lower operating cash flow.

  • Revenue remained stable sequentially but improved versus the same quarter last year. Operating cash flow was steady year-over-year but materially lower than the preceding quarter, resulting in a free cash flow margin that weakened compared to the prior quarter and was similar to the year-ago level.
  • Compared with the immediately preceding quarter, revenue was unchanged yet free cash flow and margin were both much lower due to a substantially lower operating cash flow. Versus the same quarter last year, revenue, operating cash flow, capital expenditure, and free cash flow were all higher, but the margin was slightly lower.

Watch

Operating Cash Flow Volatility

The sharp drop in operating cash flow from the preceding quarter is the strongest observable driver of the free cash flow decline, as revenue remained flat and capital expenditure was lower. The filing notes that operating cash flow was supported by higher net income but partially offset by increased working capital requirements.

This volatility in operating cash flow directly caused a materially lower free cash flow and margin in the current quarter.

What the cash flow says

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

Revenue remained stable sequentially but improved versus the same quarter last year. Operating cash flow was steady year-over-year but materially lower than the preceding quarter, resulting in a free cash flow margin that weakened compared to the prior quarter and was similar to the year-ago level.

Compared with the immediately preceding quarter, revenue was unchanged yet free cash flow and margin were both much lower due to a substantially lower operating cash flow. Versus the same quarter last year, revenue, operating cash flow, capital expenditure, and free cash flow were all higher, but the margin was slightly lower.

Monitor the trend in operating cash flow, which declined significantly from the prior quarter despite stable revenue.
