Key Takeaways:
Pentair plc shares plunged 15% on Wednesday after the water treatment company slashed its full-year outlook, reported preliminary second-quarter results well below its prior forecast, and disclosed the departure of its chief financial officer.
"The preliminary results and guidance cut point to issues having gotten materially worse," Andrew Buscaglia, senior analyst at BNP Paribas, said in a note. "We suspect the inventory dynamics relate to PNR's largest customer, Pool Corp."
The London-based company now expects 2026 sales to decline 4% to 7%, a sharp reversal from its earlier forecast of 2% to 4% growth. Adjusted earnings per share are seen at $4.60 to $4.80, down from a prior range of $5.30 to $5.40. For the second quarter, Pentair anticipates revenue of about $930 million, down 17% from its previous guidance of roughly 1% growth, and adjusted EPS of approximately $1.12, compared with the $1.47 to $1.50 it had projected 11 weeks ago.
The miss was driven entirely by destocking in the Pool segment, Pentair's most profitable division. Distributors reduced inventory ahead of the 2027 pool season, cutting pool equipment sales by about $170 million and segment income by roughly $105 million in the quarter. For the full year, the company expects the destocking drag to reach $250 million in sales and $155 million in income. Stifel analyst Nathan Jones estimated Pentair's pool equipment revenue fell 40% to 42% year over year, Reuters reported.
The CFO transition compounded the bad news. Nicholas Brazis resigned on July 10 after roughly four months in the role to pursue an opportunity at a private company. Former CFO Bob Fishman returned as interim executive vice president and CFO effective immediately. RBC Capital Markets analyst Deane Dray called the leadership change "an embarrassing development" and downgraded the stock to Sector Perform from Outperform, cutting his price target by $27 to $74.
Pentair's Flow and Water Solutions segments performed roughly in line with prior expectations, according to RBC. The company also collected an estimated $35 million to $50 million in tariff refunds tied to duties previously collected under the International Emergency Economic Powers Act, and repurchased about 2 million shares for $150 million during the quarter.
The 15% decline pushed Pentair shares to a new 52-week low of $57.60, far below the $113.95 high reached over the past year. The stock is down 38% year to date and trades at about 16 times earnings, with a dividend yield near 1.64%.
At least five law firms — including Bleichmar Fonti & Auld, Hagens Berman, Block & Leviton, Pomerantz, and Levi & Korsinsky — have announced investigations into whether Pentair misled investors about its inventory levels before the guidance cut.
The decline puts Pentair at its lowest valuation in years, testing whether the destocking is a temporary cycle or a permanent loss of market share to competitors like Hayward. The company's full second-quarter results are due before the market opens on July 28, when management will face questions about the pace of the inventory correction and the search for a permanent CFO.
