Q&A

What is this lawsuit about? 
According to the complaint, between March 11, 2025 and July 14, 2026, Pentair and certain executives failed to disclose that: (1) there was significant destocking of inventory in the Pool channel; and (2) as a result, the Company's sales and operating income were adversely affected. The truth allegedly began to emerge on July 14, 2026, after the market closed, when Pentair announced preliminary second quarter 2026 financial results, disclosing that Pool channel destocking had reduced Pool segment sales by approximately $170 million and Pool segment income by approximately $105 million. As a result, second quarter 2026 sales were expected to be down 17 percent versus the prior guide of approximately 1 percent growth, and full year 2026 sales were expected to be down approximately 4 percent to 7 percent versus the prior guide of up 2 percent to 4 percent. Pentair also announced the immediate departure of its Chief Financial Officer. On this news, Pentair's stock price fell $11.35, or 15%, to close at $64.33 per share on July 15, 2026, on unusually heavy trading volume.

Who is Pentair?

The Company operates through three segments: Flow, Water Solutions, and Pool. The Pool segment designing and selling residential and commercial pool equipment, including pumps, filters, heaters, and automatic controls.

Allegations focus on the personal accountability of Pentair's Chief Executive Officer and former Chief Financial Officer, following the alleged omission of significant Pool channel destocking before PNR shares fell $11.35 in a single session.

, /PRNewswire/ -- Levi & Korsinsky, LLP alerts investors in Pentair plc (NYSE: PNR) that a securities class action has been filed naming Chief Executive Officer John L. Stauch and former Chief Financial Officer Nicholas J. Brazis as individual defendants, on behalf of shareholders who purchased securities between April 28, 2026 and July 14, 2026. Find out if you are eligible to recover losses. You may also contact Joseph E. Levi, Esq. at [email protected] or (212) 363-7500.

PNR closed at a Class Period high of $82.86 on April 28, 2026. Following the July 14, 2026 after-hours announcement, shares closed $64.33 on unusually heavy volume. The window to apply for lead plaintiff closes on October 2, 2026.

The Named Individual Defendants

Stauch served as Chief Executive Officer throughout the Class Period. Brazis served as Chief Financial Officer until his departure on July 10, 2026, disclosed four days later alongside the revised guidance. The complaint charges that both held the power and authority to control the content of Pentair's SEC reports, press releases, and presentations to analysts and institutional investors.

Alleged Control Person Liability

The pleading asserts that the individual defendants are liable under Section 20(a) of the Securities Exchange Act of 1934 for the following:

Control over the April 28, 2026 earnings release projecting full year 2026 sales up approximately 2 to 4 percent and adjusted EPS of $5.30 to $5.40 Control over the Form 10-Q for the period ended March 31, 2026, including its inventory disclosures Receipt of internal budgets, plans, projections, and reports reflecting channel conditions in the Pool segment Authority to prevent issuance of the challenged statements or cause them to be corrected Direct and supervisory involvement in day-to-day operations of a segment that accounted for roughly 37% of fiscal 2025 net sales and 46% of reportable income Sarbanes-Oxley Certification Obligations

As averred, senior officers who sign Sections 302 and 906 certifications attest personally to the accuracy and completeness of the periodic reports they submit. The complaint charges that the certified filings omitted significant destocking of inventory in the Pool channel, which Pentair later estimated reduced Pool segment sales by approximately $170 million and Pool segment income by approximately $105 million in the second quarter alone.

"Corporate officers have a duty to ensure their companies' public statements are accurate and complete. Here, the complaint alleges that guidance affirmed in April was issued without disclosing destocking that the Company would later quantify at approximately $250 million in full year Pool segment sales." -- Joseph E. Levi, Esq.

Frequently Asked Questions About the PNR Lawsuit

Q: Who are the defendants named in the PNR lawsuit? A: The complaint names Pentair plc and individual defendants including senior executives who signed SEC filings, made public statements, or certified financial disclosures under Sarbanes-Oxley, specifically Chief Executive Officer John L. Stauch and former Chief Financial Officer Nicholas J. Brazis.

Q: What court was the PNR class action filed in? A: The case was filed in the United States District Court for the Southern District of New York, governed by the Private Securities Litigation Reform Act of 1995.

Q: What specific misstatements does the PNR lawsuit allege? A: The complaint alleges Pentair made materially false or misleading statements regarding inventory conditions in the Pool channel and full year 2026 financial guidance during the Class Period. When the Company disclosed preliminary second quarter results showing approximately $170 million of Pool segment sales impact and announced its CFO's departure, the stock price declined sharply.

Q: What is a lead plaintiff and why does it matter? A: A lead plaintiff is the investor appointed by the court to represent the entire class. Lead plaintiffs are typically investors with the largest documented losses. Being appointed does not increase individual recovery but gives direct oversight of how the case is run.

Q: What happens after I contact Levi & Korsinsky? A: An attorney will review your trading history at no cost and provide an initial assessment of your potential eligibility.

Q: What if I already sold my PNR shares -- can I still recover losses? A: Yes. Eligibility is based on when you purchased, not whether you still hold the shares. Investors who bought during the Class Period and sold at a loss may still be eligible to participate.

Q: Do I need to go to court or give testimony? A: No. The overwhelming majority of class members never appear in court or give depositions. If there is a settlement or recovery, eligible class members generally submit a claim form to seek their portion.

Q: What does it cost me to participate? A: There is no upfront cost to contact the firm. Securities class actions are generally handled on a pure contingency basis. No upfront fees, no retainer, and no out-of-pocket costs. Any attorneys' fees and expenses awarded to class counsel are subject to court approval.

San Francisco, California--(Newsfile Corp. - September 8, 2026) - Hagens Berman Sobol Shapiro LLP alerts investors in Pentair plc (NYSE: PNR) that a securities fraud class action lawsuit filed against the company has been expanded to cover an earlier class period. Investors who suffered substantial losses are urged to submit their losses now.

CASE DETAILS

Expanded Class Period: March 11, 2025 - July 14, 2026 (Previously April 28, 2026 - July 14, 2026)
Lead Plaintiff Deadline: Oct. 2, 2026
Contact Hagens Berman: Visit www.hbsslaw.com/pnr, email [email protected], or call (844) 916-0895

ALLEGED MISCONDUCT & EXPANDED CLASS PERIOD

The new class action lawsuit alleges that beginning on March 11, 2025, Pentair plc and certain of its top executives made a series of materially false and misleading statements and omitted critical adverse operational information regarding Pentair's financial health, channel inventory, and internal controls.

Specifically, the lawsuit alleges Defendants failed to disclose that:

Pentair was experiencing severe, undisclosed channel inventory destocking-particularly within its core Pool segment. The company engaged in unsustainable channel-loading and sales practices with distributors to artificially inflate short-term financial metrics. As a result, Pentair's positive statements regarding its business, full-year financial guidance, and operating income lacked a reasonable basis.THE DISCLOSURE & MARKET REACTION

The complaint alleges that the artificial inflation in Pentair shares came to an abrupt end on July 14, 2026, after the market closed, when Pentair shocked investors by pre-announcing preliminary second-quarter 2026 financial results that fell substantially below consensus estimates.

The disclosures revealed severe operational headwinds:

Massive Revenue Miss: Sales were expected to be approximately $930 million-a drastic miss against prior forecasts of $1.14 billion. The company disclosed that inventory destocking in the Pool channel negatively impacted Pool segment sales by approximately $170 million and income by approximately $105 million.Full-Year Guidance Slashed: Pentair dramatically cut its full-year 2026 outlook, reversing earlier projections. Full-year sales were projected to be down approximately 4% to 7%, compared to prior guidance of up 2% to 4% growth.Abrupt CFO Departure: Compounding the shock, Pentair announced the immediate departure of its Chief Financial Officer, Nicholas Brazis, after serving in the role for only four months, raising questions regarding internal controls and financial reporting.Following these disclosures, Pentair's stock price plummeted 15% in a single session-losing $11.35 per share to close at $64.33 on unusually heavy trading volume on July 15, 2026.

"We are closely examining the timing of these disclosures, the sudden departure of the CFO after only four months, and the severe impact of channel destocking on Pentair's financial health," said Reed Kathrein, the Hagens Berman partner leading the firm's investigation of the alleged claims.

What Affected PNR Investors Should Do

If you purchased or acquired Pentair common stock between March 11, 2025, and July 14, 2026, and suffered significant financial losses, you have until October 2, 2026, to ask the court to appoint you as lead plaintiff.

Captioned City of Warren General Retirement Health, Life and Disability Benefits Plan and Trust v. Pentair plc, No. 26-cv-03597 (D. Minn.), the Pentair class action lawsuit charges Pentair as well as certain of Pentair’s top current and former executive officers with violations of the Securities Exchange Act of 1934.

CASE ALLEGATIONS: Pentair is a global manufacturer of water solution products.

The Pentair class action lawsuit alleges defendants throughout the Class Period made false and/or misleading statements and/or failed to disclose that: (i) Pentair’s 80/20 program had failed to improve Pentair’s business and operations and had instead materially impaired Pentair’s longstanding commercial relationships, alienated its customers, and created widespread customer dissatisfaction, particularly within Pentair’s Pool segment; (ii) Pentair was losing business and market share, as a significant portion of its Pool customers had turned to competitors in response to Pentair’s 80/20 program initiatives, which had more than offset any purported benefits to Pentair’s business and financial results as a result of the implementation of the 80/20 program; (iii) Pentair’s implementation of the 80/20 program had caused certain of its remaining Pool customers to buy inventory in excess of their current needs in advance of future price increases, cannibalizing Pentair’s future sales; (iv) Pentair’s remaining Pool customers had received rebates at rates above historical norms, which had artificially inflated Pentair’s sales and revenue in the short-term at the expense of future periods; and (v) as a result of the above, Pentair was acutely exposed to material, undisclosed risks of significant financial and operational harms as a result of Pentair’s implementation of its 80/20 program.

On February 3, 2026, Pentair announced its earnings results for its fourth fiscal quarter and full year ending December 31, 2025, revealing that Pentair’s net sales were on track to grow only 1% to 2% for its first fiscal quarter of 2026, missing analyst consensus estimates by tens of millions of dollars. During the related earnings call, Pentair disclosed that net sales growth in its critical Pool business had flatlined. Pentair concurrently announced that its Chief Transformation Officer & Chief Supply Officer, Steve Pilla, was abruptly departing and that the Chief Transformation position was being eliminated. On this news, the price of Pentair ordinary shares fell more than 10%.

Then, on April 28, 2026, Pentair announced results for its first fiscal quarter ending March 31, 2026, revealing that Pentair had cut its annual net sales guidance for Pool to a range of 1% to 3% net sales growth. During the related earnings call, defendant Nicholas J. Brazis further revealed that the downward revision reflected the need of channel partners to “reduce purchases in Q2 and Q3” in light of “sell-through dynamics” experienced in the first quarter. On this news, the price of Pentair ordinary shares fell more than 12%.

Finally, on July 14, 2026, Pentair announced preliminary earnings results for its second fiscal quarter ending June 30, 2026, revealing a significant deterioration in Pool segment sales. Pentair attributed the outsized erosion in its Pool business to a “pronounced inventory realignment with major channel partners” and efforts by customers to “right siz[e]” channel inventory. Specifically, the release stated that excess inventory destocking by Pentair customers had negatively impacted its quarterly Pool net sales by approximately $170 million, implying a 40% year-over-year segment decline. As a result, Pentair revealed that total net sales in the quarter had declined by 17% and that Pentair was not, in fact, on track to achieve 2026 net sales growth of 2% to 4% as previously represented, but instead on track to suffer a 4% to 7% decline. Pentair concurrently announced that defendant Brazis was abruptly departing Pentair only four months after becoming CFO. On this news, the price of Pentair ordinary shares fell approximately 15%.

The plaintiff is represented by Robbins Geller, which has extensive experience in prosecuting investor class actions including actions involving financial fraud. You can view a copy of the complaint by clicking here.

THE LEAD PLAINTIFF PROCESS: The Private Securities Litigation Reform Act of 1995 permits any investor who purchased Pentair ordinary shares during the Class Period to seek appointment as lead plaintiff in the Pentair class action lawsuit. A lead plaintiff is generally the movant with the greatest financial interest in the relief sought by the putative class who is also typical and adequate of the putative class. A lead plaintiff acts on behalf of all other class members in directing the Pentair class action lawsuit. The lead plaintiff can select a law firm of its choice to litigate the Pentair class action lawsuit. An investor’s ability to share in any potential future recovery of the Pentair class action lawsuit is not dependent upon serving as lead plaintiff.

Investors who bought during the Class Period and sold at a loss retain the same standing as those still holding. There is no minimum loss amount, and no filing fee or retainer is required to be treated as a class member.

Investor Options at a Glance

Purchasers who acquired PNR between April 28, 2026 and July 14, 2026 may qualify as class members. Class members who take no action before the lead plaintiff date generally remain eligible for any court-approved recovery. Investors seeking a supervisory role may apply for lead plaintiff appointment; courts typically consider the applicant with the largest provable loss. Documentation is straightforward: brokerage confirmations showing purchase dates, share counts, prices paid, and any sale prices. Securities cases of this type are generally handled on contingency, with any fees subject to court approval. Why the Class Period Boundaries Matter

The action alleges that statements about inventory and full year 2026 guidance made on April 28, 2026 omitted significant destocking in the Pool channel, a segment that accounted for roughly 37% of net sales in fiscal 2025. Plaintiffs contend that the July 14, 2026 preliminary results, which quantified an estimated $170 million sales impact and $105 million income impact for the quarter, corrected the prior alleged misstatements.

"Shareholders should understand that participation rights in a securities class action depend largely on purchase timing, and the Pentair Class Period is defined narrowly around the April 28 and July 14, 2026 disclosures," -- Joseph E. Levi, Esq.

Frequently Asked Questions About the PNR Lawsuit

Q: Who is eligible to join the PNR investor lawsuit? A: Investors who purchased PNR stock or securities between April 28, 2026 and July 14, 2026 and suffered financial losses may be eligible. Eligibility is based on purchase date and documented losses, not on whether you still hold the shares.

Q: What is the PNR lead plaintiff deadline? A: The deadline to apply for lead plaintiff appointment is October 2, 2026. This deadline applies only to investors seeking to serve as lead plaintiff. Class members who do not apply may still participate in any recovery without taking action before this date.

Q: Who are the defendants named in the PNR lawsuit? A: The complaint names Pentair plc and individual defendants including senior executives who signed SEC filings, made public statements, or certified financial disclosures under Sarbanes-Oxley.

Q: What if I already sold my PNR shares -- can I still recover losses? A: Yes. Eligibility is based on when you purchased, not whether you still hold the shares. Investors who bought during the Class Period and sold at a loss may still be eligible to participate.

Q: What if my PNR losses are small -- is it still worth contacting a lawyer? A: Yes. There is no minimum loss amount required to participate as a class member.

Q: Do I need to go to court or give testimony? A: No. The overwhelming majority of class members never appear in court or give depositions. If there is a settlement or recovery, eligible class members generally submit a claim form to seek their portion.

Q: What documents do I need to submit my information? A: Brokerage statements or trade confirmations showing purchase dates, share quantities, prices paid, and any subsequent sale dates and prices.

Q: What if I live outside the United States? A: U.S. securities class actions generally cover purchases on U.S. exchanges regardless of the investor's country of residence.

Market reaction angle: PNR shares declined 15% to close at $64.33 on unusually heavy volume after Pentair disclosed that Pool channel destocking allegedly stripped $170 million from segment sales.

, /PRNewswire/ -- Levi & Korsinsky, LLP alerts investors in Pentair plc (NYSE: PNR) of a pending securities class action on behalf of shareholders who purchased securities between April 28, 2026 and July 14, 2026. Find out if you may qualify to recover losses. You may also contact Joseph E. Levi, Esq. at [email protected] or (212) 363-7500.

PNR closed at a Class Period high of $82.86 on April 28, 2026. Following the July 14, 2026 after-hours announcement, shares fell $11.35, or 15%, to close at $64.33 on July 15, 2026, on unusually heavy trading volume. To be considered for lead plaintiff, investors must file by October 2, 2026.

How the Market Repriced PNR Shares

The pleading asserts that Pentair's April 28, 2026 outlook created an unrealistically positive view of the Company's Pool business. On July 14, 2026, Pentair reported preliminary second quarter sales of approximately $930 million, down 17 percent against prior guidance of up approximately 1 percent, and cut full year 2026 sales guidance to down approximately 4 percent to 7 percent from up 2 percent to 4 percent.

The trading response, as averred, reflected the removal of alleged artificial inflation rather than a routine earnings reaction. The same release disclosed a Chief Financial Officer transition effective immediately.

Alleged Market Impact by the Numbers

Class Period high closing price: $82.86 per share on April 28, 2026 Single-day decline: $11.35 per share, or 15%, to $64.33 Pool channel destocking impact on Q2 segment sales: approximately $170 million Pool channel destocking impact on Q2 segment income: approximately $105 million Full year 2026 estimated destocking impact: approximately $250 million in sales and $155 million in income Full year GAAP EPS guidance reduced to $3.90 to $4.10 from $4.83 to $4.93 Why the Volume Spike Matters

The complaint charges that the Pool segment accounted for roughly 37% of net sales and 46% of reportable income in fiscal 2025, making channel inventory conditions material to any reasonable assessment of PNR. The heavy trading volume on July 15, 2026 is alleged to demonstrate that the destocking information was material and previously unknown to the market.

"Corporate officers have a duty to ensure their companies' public statements are accurate and complete. The complaint alleges that Pentair's April 2026 guidance omitted significant Pool channel destocking that later contributed to a 17 percent sales shortfall." -- Joseph E. Levi, Esq.

Q: How much did PNR stock drop? A: Shares fell approximately 15%, a decline of $11.35 per share, after the Company disclosed that Pool channel destocking reduced Pool segment sales by approximately $170 million and cut full year 2026 guidance.

Q: What do PNR investors need to do right now? A: Gather brokerage records including purchase dates, share quantities, and prices paid. Contact Levi & Korsinsky for a free, no-obligation evaluation at [email protected] or (212) 363-7500. No immediate action is required to remain eligible as an absent class member.

Q: What if I already sold my PNR shares -- can I still recover losses? A: Yes. Eligibility is based on when you purchased, not whether you still hold the shares. Investors who bought during the Class Period and sold at a loss may still be eligible to participate.

Q: Do I need to go to court or give testimony? A: No. The overwhelming majority of class members never appear in court or give depositions. If there is a settlement or recovery, eligible class members generally submit a claim form to seek their portion.

Q: What does it cost me to participate? A: There is no upfront cost to contact the firm. Securities class actions are generally handled on a pure contingency basis.
