Chronology of Material Events

April 28, 2026 — Pentair announced first quarter 2026 results and raised its full year outlook. Reported sales came in at $1,037 million, up 3 percent year over year, with operating income of $210 million. Full year 2026 sales were guided up approximately 2 to 4 percent, GAAP EPS to approximately $4.83 to $4.93, and adjusted EPS to approximately $5.30 to $5.40. Second quarter sales were guided up approximately 1 percent. The Company filed its Form 10-Q for the period ended March 31, 2026 the same day. The filing states that these inventory and guidance representations were materially false and misleading because they allegedly omitted the significant destocking then occurring in the Pool channel.

April 28, 2026 through July 13, 2026 — No corrective disclosure regarding Pool channel inventory conditions was issued during this period, as set forth in the complaint. Pool represented roughly 37 percent of net sales and 46 percent of reportable income in fiscal 2025.

July 14, 2026, after the close — Pentair released preliminary second quarter 2026 results, announced the Company's Chief Financial Officer departed the company, and revised full year guidance downward.

July 15, 2026 — Shares closed at $64.33.

Timeline of Alleged Disclosure Failures

• April 28, 2026: Second quarter sales guided up approximately 1 percent; actual preliminary result later reported as down 17 percent, to approximately $930 million.
• April 28, 2026: Full year sales guided up 2 to 4 percent; revised on July 14, 2026 to down approximately 4 percent to 7 percent.
• April 28, 2026: Full year GAAP EPS guided to $4.83 to $4.93; revised to approximately $3.90 to $4.10.
• April 28, 2026: Full year adjusted EPS guided to $5.30 to $5.40; revised to approximately $4.60 to $4.80.
• July 14, 2026: Pool channel destocking estimated to have reduced second quarter Pool segment sales by approximately $170 million and segment income by approximately $105 million.
• July 14, 2026: Full year Pool destocking impact estimated at approximately $250 million in sales and $155 million in income, tied in part to right sizing channel inventory ahead of the 2027 pool season.

"Timely disclosure of material developments is fundamental to fair and efficient markets. Here the question is whether the scale of Pool channel destocking, later estimated at approximately $250 million in full year sales, was known internally while the Company was raising its outlook in April 2026." -- Joseph E. Levi, Esq.

What the July 14 Announcement Changed for Shareholders

The action is pending in the United States District Court for the Southern District of New York and asserts claims under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 and Rule 10b-5. It alleges that purchasers acquired PNR shares at artificially inflated prices between April 28, 2026 and July 14, 2026 and were damaged when the revised figures reached the market.

Frequently Asked Questions About the PNR Lawsuit

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 2026 results showing Pool channel destocking reduced segment sales by approximately $170 million, along with sharply reduced full year 2026 guidance and a CFO departure. Investors who purchased shares during the Class Period at artificially inflated prices and suffered losses may be eligible to seek compensation.

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 its resulting sales and operating income guidance during the Class Period. When the destocking impact and revised guidance were disclosed, the stock price declined sharply.

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 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 documents do I need to 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 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: 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.
