CFO TRANSITION

John L. Stauch, President and Chief Executive Officer of Pentair, said, "Our Board and leadership team are pleased to have Bob Fishman rejoin Pentair on an interim basis as we conduct a search for his successor. During Bob’s six year tenure at Pentair, he helped to strengthen our financial foundation and enhance our operating discipline. Given his deep financial expertise, clear understanding of our business and strong relationships across Pentair and the financial community, I am confident he will step back in seamlessly as we execute on our key strategic and financial priorities to build long-term value."

Bob Fishman said, "I’m excited to return to Pentair and support the company during this transition. Pentair has a strong portfolio, talented team and clear strategy for long-term success. I’m optimistic about the opportunities ahead and look forward to working alongside John and the team to support disciplined execution and create value for our customers, shareholders and employees."

PRELIMINARY SECOND QUARTER 2026 RESULTS AND FULL YEAR 2026 GUIDANCE

Separately, the company also announced today preliminary results for the second quarter 2026 and provided revised guidance for the full year 2026.

Preliminary Second Quarter 2026 Results:

• Sales are expected to be approximately $930 million, down 17 percent versus previous guide of up approximately 1 percent primarily due to the adverse impact of Pool channel inventory
• Operating income from continuing operations is expected to be approximately $165 million; Adjusted Operating Income is expected to be approximately $235 million as the result of the adverse impact of Pool channel inventory and the positive impact of recoveries of tariffs previously collected under the International Emergency Economic Powers Act ("IEEPA")
• Earnings per diluted share from continuing operations ("EPS") are expected to be approximately $0.80 versus previous guidance of $1.39 to $1.42; Adjusted EPS is expected to be approximately $1.12 versus previous guide of $1.47 to $1.50 as the result of the adverse impact of Pool channel inventory and the positive impact of IEEPA refunds
• The company estimates that the destocking of inventory in the Pool channel negatively impacted Pool segment sales by approximately $170 million and Pool segment income by approximately $105 million
• The company’s results are expected to include approximately $35 million of IEEPA refunds

Revised Full Year 2026 Guidance:

• Sales are expected to be down approximately 4 percent to 7 percent versus previous guide of up 2 percent to 4 percent mostly attributable to destocking of inventory in the Pool channel and right sizing of channel inventory in preparation for the 2027 pool season
• Operating income from continuing operations is expected to be down approximately 1 percent to 6 percent; Adjusted Operating Income is expected to be down approximately 5 percent to 9 percent as the result of the adverse impact of Pool channel inventory and the positive impact of IEEPA refunds
• GAAP EPS is expected to be approximately $3.90 to $4.10 versus the previous guide of $4.83 to $4.93; Adjusted EPS is expected to be approximately $4.60 to $4.80 versus previous guide of $5.30 to $5.40 as a result of the adverse impact of Pool channel inventory and the positive impact of IEEPA refunds
• The company’s net income from continuing operations for the year is expected to be approximately $635 million to $670 million; EBITDA for the year is expected to be approximately $1,050 million
• The company estimates that the destocking of inventory in the Pool channel negatively impacts Pool segment sales by approximately $250 million and Pool segment income by approximately $155 million
• The company’s results are expected to include approximately $35 million to $50 million of IEEPA refunds

Reconciliations of GAAP to non-GAAP measures are in the attached financial tables.

Second quarter performance was impacted by a decline in Pool sales largely attributed to a more pronounced inventory realignment with major channel partners than previously estimated and worsening business conditions, including higher interest rates and inflation. The company’s full year 2026 guidance includes destocking of inventory in the Pool channel and right sizing of channel inventory in preparation for the 2027 pool season. Pentair is taking decisive actions to address near-term challenges in the Pool segment by strengthening its relationships with channel partners – including dealers, distribution partners, and service professionals – accelerating the development of new, innovative products and enhancing its technical support solutions. With the leading brand position in the industry, and the most advanced technology to serve customers, Pentair is confident in the fundamentals of its Pool business and the compelling opportunities ahead to drive growth.

The company’s Flow and Water Solutions segments and corporate spending are expected to perform roughly in line with prior guidance for the second quarter and full year 2026.

In addition, the company repurchased approximately 2.0 million shares for $150 million during the second quarter of 2026.

John L. Stauch, Pentair’s President and Chief Executive Officer commented, "We believe these headwinds are temporary and we are taking decisive actions to adapt the business to current demand levels while positioning it to return to normalized performance in 2027. We are confident that these actions will bring us closer to our dealers, accelerate innovation and drive long-term growth. Our Pool business is an industry leader with a premier brand, strong customer base, and a large install base, with leading positions in energy-efficient and smart connected pool technologies. Importantly, our Flow and Water Solutions segments performed generally in line with expectations as we continue to successfully execute our growth agenda, demonstrating the strength and balance of our portfolio."

Bob Fishman said, "We have assessed our full year forecast and feel confident that we can execute successfully in 2026 and position ourselves for significant growth in 2027. With a solid balance sheet, strong cash flow, a balanced capital deployment strategy and a resilient business model, we remain well positioned to deliver long-term shareholder value."
