Pentair plc (ISIN IE00BLS0VV05) stock is quoted at $62.10 as of August 28, 2026, with the shares trading well below their recent 52-week high after a sharp July setback linked to securities litigation headlines.
The latest price context from a market-data overview on Pentair as of August 28, 2026 indicates a closing share price of $62.10, with the stock down 45.50 percent from its 52-week high and up 7.81 percent from its 52-week low, underscoring the volatility investors have faced in recent months. This same snapshot notes an intraday high of $62.62 and low of $61.46 for the most recent session, giving a sense of the current trading range.
At the fundamental level, Pentair’s most recent quarterly figures for Q2 2026 show adjusted earnings per share of $1.14, modestly above the company’s own guidance for the period, while revenue came in at $932.6 million, down 17 percent year over year as the pool business softened. These results frame the company’s valuation and help explain why the market reaction has been more nuanced than the headline share-price drop might suggest.
Q2 2026 earnings highlight margin story
In its second quarter of 2026, Pentair reported adjusted EPS of $1.14, surpassing its stated expectation of $1.12 for the period. Taken together, this represents a small upside of $0.02 per share against guidance, even though adjusted EPS fell 18 percent compared with the $1.39 recorded in the year-ago quarter, highlighting the pressure from weaker pool-related demand.
The same Q2 2026 disclosure shows revenues of $932.6 million, a decline of 17 percent versus the comparable quarter a year earlier, and below the roughly $1.012 billion level that had been anticipated by market consensus, with the company having signaled an expectation of around $930 million heading into the report. Despite the revenue contraction, Pentair’s cost of goods sold decreased 19.3 percent to $537.6 million, which contributed to a gross profit of $395 million and an expansion of gross margin to 42.4 percent from 40.7 percent in the prior-year quarter.
The operating metrics underline that Pentair has been working to protect profitability even as volume trends soften. Reported operating income in Q2 2026 dropped 23.5 percent to $166.5 million, with return on sales contracting to 17.9 percent. On an adjusted basis, operating income declined 20 percent year over year to $237 million, corresponding to an adjusted return on sales of 25.4 percent, slightly lower than the prior-year level but still indicating healthy margins for a diversified water and flow solutions provider.
Segment data provide further context. In one of Pentair’s key divisions, segment income rose 27 percent to $69.8 million in Q2 2026, and segment return on sales expanded by 470 basis points to 26.5 percent. In the Water Solutions area, sales declined 5 percent to $422 million, with core sales down 3 percent, yet the company managed to balance this with improvements elsewhere and a focus on higher-value offerings. These figures together tell a story of a business coping with pockets of weakness while leveraging margin expansion where possible.
Balance sheet, cash flow and capital allocation
Pentair’s Q2 2026 report also offers insight into its financial position and capital allocation choices. Free cash flow for the period totaled $552.9 million, versus $595.8 million in the prior-year quarter, demonstrating that the company continues to generate substantial cash even in a more challenging demand environment. This cash flow supports ongoing investments, shareholder returns and strategic acquisitions.
As of the end of the second quarter of 2026, Pentair held $91.8 million in cash and cash equivalents and carried $1.61 billion of long-term debt on its balance sheet. The company repurchased $150 million of shares during the quarter and still had $650 million remaining under its share repurchase authorization, signaling continued commitment to returning capital to shareholders alongside operational investments.
From an investor’s perspective, these numbers point to a mixed but not structurally weak backdrop: earnings and revenue are under pressure versus the prior year, but margins, cash generation and buybacks suggest management is actively steering through the cycle. The Q2 2026 metrics are also timely in the context of the recent litigation-driven share-price volatility, as they provide a reference point for assessing whether the current valuation aligns with the underlying performance.
Litigation-driven volatility and recent price moves
Legal developments have added an extra layer of risk perception around Pentair stock in July and August 2026. A securities fraud class action has been filed against the company on behalf of investors, with a filing deadline set for October 2, 2026. One detailed notice of the action reports that following disclosures related to the case, Pentair’s stock price fell 15 percent in a single session, shedding $11.35 per share to close at $64.33 on heavy trading volume on July 15, 2026.
A separate law-firm announcement covering the same case states that on the relevant news, the price of Pentair’s stock dropped 15 percent, reinforcing the picture of an abrupt market repricing. For retail investors studying the stock as of late August 2026, the combination of that mid-July decline and today’s $62.10 level underscores how the litigation headlines have intersected with an already volatile fundamental backdrop.
Seen against the Q2 2026 earnings numbers, the current price zone in the low-$60s positions Pentair shares below where they traded before the 15 percent drop, while still reflecting margins that remain robust by historical standards. The quantified comparison between the $64.33 close on July 15, 2026 after the litigation-related selloff and the $62.10 price as of August 28, 2026 suggests that the stock has not fully recovered, even though the company’s operational performance has not deteriorated further in reported figures since the quarter.
Representative product: water treatment and filtration solutions
Pentair is best known to many consumers and commercial customers for its water treatment and filtration solutions, including systems designed to improve residential drinking water quality and manage water usage efficiently in industrial and agricultural settings. These products sit at the heart of the company’s Water Solutions segment, which generated $422 million of sales in Q2 2026 despite a modest decline compared with the prior-year quarter.
The company’s offerings range from point-of-entry filtration systems for homes and businesses to advanced membranes and pumps that support large-scale water-management projects. In practice, this means that Pentair’s performance is tied not only to cyclical demand in areas like pools, but also to long-term structural trends such as the need for reliable water infrastructure, regulatory focus on water quality and increasing pressure to optimize resource usage. For investors, the product suite helps explain why margins can remain resilient even when one end market, such as pool equipment, experiences a temporary slowdown.
Pentair stock at $62.10 as of August 28, 2026
As of August 28, 2026, 8:46 a.m. local time in the reference quote, Pentair stock is reported at $62.10, with the day’s high and low marked at $62.62 and $61.46 respectively in that same source. The stock’s position, 45.50 percent below its 52-week high yet 7.81 percent above its 52-week low, reflects both the impact of the July 15, 2026 15 percent drop connected to the securities class action disclosures and the broader adjustment to softer Q2 2026 earnings.
For US retail investors considering Pentair, this price level and volatility profile indicate that the market has already priced in a mix of legal risk and cyclical pressure on revenue, while still assigning value to the company’s margin strength, cash generation and share repurchases. The coming months, including any future quarterly updates and developments in the class action, will determine whether the current low-$60s range represents a consolidation zone or a stepping stone to a different valuation band.
