Pentair plc (NYSE: PNR), a leading global water solutions provider, has agreed to acquire Hydra-Stop LLC, a US-based manufacturer of specialty valve solutions, in a $290 million cash deal. The acquisition, expected to close by the end of 2025, subject to regulatory clearance and other conditions, aims to enhance Pentair's existing solutions and support the growing water needs of cities.

Hydra-Stop, founded in 1981, specializes in safe, efficient, and cost-effective insertion valves and line stop fittings, serving water utility service providers and municipalities in the United States. The company employs more than 50 team members and generates approximately 99% of its sales in the US. For full year 2025, Hydra-Stop is expected to generate around $50 million in revenue, with a Return on Sales of approximately 30% [1].

De’Mon Wiggins, Executive Vice President and President of Pentair Flow, stated, "This strategic acquisition will help accelerate our growth initiatives for our commercial and infrastructure business by supporting municipalities and their service providers in addressing critical water issues" [1]. Upon completion, Hydra-Stop will operate within Pentair's Commercial and Infrastructure business unit of its Flow business segment.

The acquisition is expected to net approximately $240 million after accounting for expected tax benefits of around $50 million [1, 2]. Pentair, with a strong financial health rating and a market cap of $17.2 billion, appears well-positioned to finance this deal [2].

Recent financial performance has been robust for Pentair. The company reported second-quarter 2025 earnings that surpassed analyst expectations, leading to an increase in full-year guidance. Despite the strong performance, shares experienced a slight dip in pre-market trading due to mixed guidance [2].
