Pentair's Q3 2026 Earnings Disclosure and Non-GAAP Financial Measure Framework

Pentair plc (NYSE:PNR), incorporated in Ireland and headquartered at Regal House, 70 London Road, Twickenham, London, filed this Form 8-K under Item 2.02 (Results of Operations and Financial Condition) on October 27, 2026. The filing attaches a press release as Exhibit 99.1 announcing the company's third-quarter 2026 earnings, with a conference call also referenced in connection with the release.

The filing describes several non-GAAP financial measures the company uses alongside its GAAP results. According to the filing, "core sales" refers to GAAP net sales from continuing operations excluding the impact of currency translation and the impact of net sales from acquired businesses recorded prior to the first anniversary of the acquisition. The filing explains that management utilizes these adjusted measures "to assess the run-rate of its continuing operations against those of prior periods without the distortion of these factors." The company also noted that its non-GAAP measures "may not be comparable to similarly titled measures reported by other companies."

Regarding free cash flow, the filing states the company "believes free cash flow is an important measure of liquidity because it provides the Company and its investors a measurement of cash generated from operations that is available to pay dividends, repurchase shares and repay debt." The 2025 adjusted figures, as described in the filing, additionally eliminated items including certain legal accrual adjustments and settlements, asset impairment and write-offs, loss on sale of business, pension and other post-retirement mark-to-market loss, and certain tax items - categories not listed among the 2026 adjustments.
