Pentair plc (US7096311052) stock closed at USD 64.33 on July 15, 2026 after a 15 percent drop, and the latest available market snapshot in this call shows the shares at USD 55.92 with a market cap of USD 8.925 billion on September 19, 2026.

Guidance cut still shapes the story

According to Stockhouse, Pentair said on July 14, 2026 that second-quarter sales should be about USD 930 million, down 17 percent versus the previous guide of up about 1 percent. The same report said adjusted EPS should be about USD 1.12 versus prior guidance of USD 1.47 to USD 1.50, while full-year 2026 sales were cut to down about 4 percent to 7 percent from a prior range of up 2 percent to 4 percent.

That revision matters more than the later legal follow-up. It gave the market a concrete sales reset of roughly USD 210 million versus the earlier second-quarter plan of about USD 1.14 billion and showed how sharply Pool-channel destocking hit the outlook.

What the market is pricing

Pentair shares trade 13.0 percent below the July 15 close of USD 64.33 and sit 28.1 percent below the intraday high of USD 77.56 from September 2026 based on the figures in this call. The latest Yahoo Finance snapshot also puts the 52-week range at USD 51.99 to USD 100.50 and volume at 1,810,452 shares on September 18, 2026.

For investors, the comparison is clear: the stock is still being judged against the July 14 reset, not against a fresh upgrade cycle. The next visible catalyst in the material from this call is the market's reaction to whether the revised 2026 guide proves conservative or not.

Key figures to watch

Yahoo Finance lists Pentair at USD 55.92 on September 19, 2026, with a market capitalization of USD 8.925 billion and a year-to-date gain of 5.51 percent. It also shows trailing revenue of USD 6.06 billion, trailing net income of USD 324 million and diluted EPS of USD 4.86, which frame the valuation after the guidance shock.
