Pentair's filings show steady profit growth alongside tariff refund uncertainty and a dense MD&A.
The four readings.
What the filing actually says.
The 2025 annual figures are broadly consistent with the narrative of improving profitability. Operating cash flow of $814.8 million exceeded net income of $653.8 million, a ratio of 1.25, which means reported earnings were backed by cash generated from operations in that year. Long-term debt fell from $1.99 billion at the end of 2023 to $1.64 billion at the end of 2025, and was unchanged from 2024. Equity grew to $3.87 billion, while total liabilities of $3.0 billion were below the $3.35 billion reported for 2023. The forensic screens point in a similar direction, but each needs to be read on its own terms. The Beneish M-Score of -2.573 is below the -1.78 threshold and is not in the elevated manipulation-risk zone; this is a screening result, not proof that the reported numbers are accurate. The Altman Z-Score of 4.09 is in the safe zone under the label provided, which indicates a low distress signal under that model. The Piotroski F-Score is 8 of 9 computable signals, meaning eight of the nine simple financial-strength tests that could be computed were passed. The Fog Index of 16.53 is in the hard-to-read band, so the MD&A demands more effort than typical filings. Readers may want to look at the tariff and Pillar Two discussions in Item 7, how the Hydra-Stop purchase price was allocated in the 10-K notes, and whether future filings quantify the revenue effect of the 80/20 exits. The excerpts provided do not separate the effect of pricing actions from the effect of tariffs on margins, so that question remains open.
Catalyst.According to the Item 7 MD&A in the 10-Q for the quarter ended March 31, 2026, management points to its Transformation Program, 80/20 guiding principles, and business restructuring as the main levers for margin expansion. The 2025 annual results give the latest full-year backdrop: revenues rose 2.3% to $4.18 billion from $4.08 billion, operating income climbed to $857.5 million from $803.8 million, and net income reached $653.8 million versus $625.4 million. The company completed the $292.1 million cash acquisition of Hydra-Stop in September 2025, which sits in the Flow segment. Effective January 1, 2026, management reorganized segments by moving the legacy residential and irrigation flow business into Water Solutions, while the Pool segment is unchanged.
Hidden risk.The most material tension is between management's margin story and the cost and revenue exposure described elsewhere in the filings. The MD&A says inflationary costs, including tariffs, will likely persist throughout 2026, and that transformation costs will continue beyond 2026. Management also says the 80/20 approach may involve reducing lower-margin sales, and the risk factors state that revenues could be reduced by exiting certain customers and products. Refunds for IEEPA tariffs struck down by the U.S. Supreme Court on February 20, 2026 remain uncertain in timing and amount. Separately, the MD&A has a Fog Index of 16.53, which falls in the hard-to-read band, so the narrative is dense for a casual reader.

Shares that traders have borrowed and sold, betting the price will fall, and not yet bought back. Brokers report the total to FINRA twice a month. Days to cover divides it by the shares that change hands on a typical day.

What it tells us
A noticeable minority of traders is betting that PNR shares will fall.
Short sellers closed some of their bets: shares sold short fell 12.3% since the Aug 31 report.
At normal trading volume, short sellers would need about 2.1 days to buy back every borrowed share.
How investors use it
- Squeeze watching. Some aggressive traders seek out heavily shorted stocks, betting that good news will force short sellers to buy back shares and push the price higher.
- Hedging. Funds short one company to offset risk in another, often owning a stronger business and shorting a weaker one in the same industry.
- Timing. Chart-based traders pair rising short interest with price patterns, such as a break below a level where buyers used to step in, to decide when to enter or exit.
- Warning sign. Some owners treat a sharp rise in short interest as a red flag and respond by tightening stop-loss orders or holding smaller positions.
