Pentair stock falls to a 52 week low after weak sales

Pentair plc (IE00BLS0VV05) stock traded at USD 55.97 on September 17, 2026, after touching a 52 week low of USD 55.97 and a 52 week high of USD 113.95, while Yahoo Finance showed a market cap of USD 9.011 billion and volume of 2,294,492 shares on the same snapshot.

Q2 FY26 set the tone

Yahoo Finance's Pentair page showed Q2 FY26 revenue of USD 932.6 million and earnings of USD 128.6 million, with profit margin at 13.79 percent. The same snapshot listed adjusted EPS of USD 1.14 versus the estimate of USD 1.147, a small miss in a quarter that still left the company close to consensus.

Investing.com said on September 17, 2026 that Pentair's stock reached a 52 week low at USD 55.97, down from the 52 week high of USD 113.95. That puts the share price at exactly half the top of the range, which matters more than the daily change on a thin news day.

Analyst tone stayed positive

Yahoo Finance also showed that Wolfe Research upgraded Pentair on September 15, 2026 to Outperform and set a price target of USD 91. The same page listed an average analyst target of USD 77.36 and a high target of USD 94.00.

For investors, the gap between USD 55.97 and USD 91 is the number to watch, because it is larger than the one-day move and much larger than the current market cap of USD 9.011 billion.

Price and range

Pentair stock closed at USD 55.97 on September 17, 2026, on the NYSE, with a prior close of USD 56.58 and a daily change of minus 0.21 percent. The current quote sits near the bottom of a 52 week range that stretches from USD 55.99 to USD 113.95.
