PNR Shareholder Alert: October 2, 2026 Lead Plaintiff Deadline in Pentair plc Securities Class Action - Contact SueWallSt

Promise vs. reality: Pentair guided investors to full year 2026 sales growth of 2 to 4 percent and adjusted EPS of $5.30 to $5.40, then updated to an expected sales decline of 4 to 7 percent and adjusted EPS of $4.60 to $4.80 after allegedly undisclosed Pool channel destocking surfaced.

NEW YORK, Sept. 24, 2026 /PRNewswire/ -- SueWallSt notifies investors in Pentair plc (NYSE: PNR) that a class action has been filed on behalf of shareholders who purchased securities between April 28, 2026 and July 14, 2026. Find out if you could qualify to recover your per-share losses. You may also contact Joseph E. Levi, Esq. at [email protected] or (888) SueWallSt.

PNR closed at $75.68 on July 14, 2026. After the guidance revision, the stock fell $11.35 per share, or 15%, on unusually heavy trading volume to close at $64.33. The last day to move for lead plaintiff is October 2, 2026.

The Promise

On April 28, 2026, the Company projected positive full year 2026 sales growth of approximately 2 to 4 percent, GAAP EPS of $4.83 to $4.93, and adjusted EPS of $5.30 to $5.40. Second quarter sales were guided up approximately 1 percent, with second quarter adjusted EPS of approximately $1.47 to $1.50.

The Reality

On July 14, 2026, after the market closed, the Company reported preliminary second quarter sales of approximately $930 million, down 17 percent against the previous guide, and revised full year sales guidance to project an approximate 4 to 7 percent decline. The lawsuit maintains that the April guidance omitted significant destocking of inventory in the Pool channel that was already affecting sales and operating income.

Promise vs. Actual: By the Numbers

• Full year 2026 sales: promised up 2 to 4 percent; revised to down 4 percent to 7 percent
• Q2 2026 sales: guided up approximately 1 percent; reported down 17 percent, at approximately $930 million
• Full year GAAP EPS: promised $4.83 to $4.93; revised to $3.90 to $4.10
• Full year adjusted EPS: promised $5.30 to $5.40; revised to $4.60 to $4.80
• Q2 adjusted EPS: guided $1.47 to $1.50; reported approximately $1.12
• Pool channel destocking impact: approximately $170 million in Q2 segment sales and $105 million in segment income; approximately $250 million in sales and $155 million in income for the full year

Plaintiffs assert that the gap between the April projections and the July results reflects conditions that existed when the earlier guidance was issued, rather than developments that arose afterward.

"When a company reduces full year adjusted earnings guidance from $5.30 to $5.40 down to $4.60 to $4.80 within a few weeks, investors are entitled to ask what was known internally at the time of the original projection. The complaint alleges the Pool channel inventory situation was material and undisclosed." -- Joseph E. Levi, Esq.

Frequently Asked Questions About the PNR Lawsuit

Q: What specific misstatements does the PNR lawsuit allege? A: The complaint alleges Pentair made materially false or misleading statements regarding inventory conditions and full year 2026 financial guidance during the Class Period, failing to disclose significant destocking in the Pool channel. When the Company disclosed that Pool channel destocking reduced segment sales by approximately $170 million and cut full year guidance, the stock price declined sharply.

Q: How much did PNR stock drop? A: Shares fell approximately 15%, a decline of $11.35 per share, after the Company disclosed preliminary second quarter results, revised full year 2026 guidance, and a CFO departure. Investors who purchased during the Class Period at artificially inflated prices and suffered losses may be eligible to seek compensation.

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 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 do PNR investors need to do right now? A: Investors may gather brokerage records showing purchase dates, share quantities, and prices paid. Contact SueWallSt, a brand of Levi & Korsinsky LLP, for a no-cost, no-obligation case 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: What does it cost me to participate? A: There is no upfront cost to submit your information and review whether you may be eligible to recover. Should you choose to participate in the securities class action, they are generally handled on a contingency basis, with any attorneys' fees and expenses subject to court approval.

Q: How long will the lawsuit take to resolve? A: Securities class actions typically take two to four years from initial filing to resolution. Timing depends on the court schedule, case developments, and whether the matter is dismissed, settled, or litigated further.
