Pentair (PNR) Free Cash Flow & Quarterly History

Explore Pentair plc (PNR) 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.

Pentair's first-quarter free cash flow turned deeply negative, driven by a substantial shortfall in operating cash flow despite stable revenue. The cash conversion weakened sharply compared with both the prior quarter and the same quarter last year, reflecting typical seasonal cash usage.

  • Revenue remained stable from the prior quarter and the year-ago quarter, yet operating cash flow swung from positive to negative, causing free cash flow to turn negative at a wider margin. Capital expenditure was slightly lower than the prior quarter but higher than a year ago, amplifying the cash conversion decline.
  • Relative to the prior quarter, operating cash flow and free cash flow both weakened significantly, with free cash flow margin dropping from positive to negative. Compared with the same quarter last year, free cash flow was also lower, though the year-ago period was already negative.

Recent events shaping cash flow

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

Watch

Seasonal operating cash flow swing

The primary observable driver was the large negative swing in operating cash flow, which moved from a positive amount in the prior quarter to a negative amount, and was also worse than the negative level a year ago. Filing context notes consistent seasonal cash usage in the first quarter.

This seasonal cash outflow directly caused free cash flow to turn negative and widened the negative margin compared with both prior periods.

What the cash flow says

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

Revenue remained stable from the prior quarter and the year-ago quarter, yet operating cash flow swung from positive to negative, causing free cash flow to turn negative at a wider margin. Capital expenditure was slightly lower than the prior quarter but higher than a year ago, amplifying the cash conversion decline.

Relative to the prior quarter, operating cash flow and free cash flow both weakened significantly, with free cash flow margin dropping from positive to negative. Compared with the same quarter last year, free cash flow was also lower, though the year-ago period was already negative.

Monitor whether operating cash flow reverses to positive in the second quarter, as seasonal patterns described in the filing suggest a return to significant cash generation.
