Material Changes vs. Prior Period
- Revenue Growth: Consolidated net sales increased 2.3% driven by a 4.0% price increase and favorable currency effects, partially offset by a 2.1% volume decline. The Pool segment was the primary growth driver (+8.5%), while Water Solutions declined (-6.1%) due to business exits and lower volume.
- Margin Expansion: Gross margin improved by 130 basis points to 40.5%, aided by pricing actions and productivity gains from the Transformation Program, despite inflationary pressures on raw materials and tariffs.
- Acquisitions: Completed the acquisition of Hydra-Stop, LLC for $292.1 million (Flow segment) in September 2025. In late 2024, acquired G & F Manufacturing for $116.0 million (Pool segment).
- Impairments and Charges: Recorded $49.1 million in asset impairments and write-offs, including a $30.9 million write-off of a customer relationship intangible asset in the Water Solutions segment due to a business exit. A $26.3 million loss on sale of business was also recorded.
- Debt Reduction: Repaid $250.0 million of the Term Loan Facility in Q2 2025, reducing net interest expense by 21.7% year-over-year.
Guidance, Outlook, and Risks
- Transformation Program: Management continues to execute a Transformation Program focused on operational excellence, cost reduction, and margin expansion. The company implemented "80/20" guiding principles to focus on high-value customers and products.
- Capital Allocation: The Board authorized a new $1.0 billion share repurchase program in December 2025. Dividends were increased by 8% to $0.27 per share, marking the 50th consecutive year of dividend increases.
- Tax Environment: The effective tax rate increased to 14.1% in 2025 (from 13.0% in 2024), impacted by the OECD Pillar Two global minimum tax rules and a decrease in favorable unrecognized tax benefits.
- Key Risks:
- Macroeconomic & Trade: Exposure to inflation, tariffs (including potential new U.S. tariffs), and global economic instability.
- Supply Chain: Continued volatility in raw material costs (metals, resins) and logistics.
- Customer Concentration: One customer in the Pool segment represented approximately 18% of consolidated net sales in 2025.
- Legal & Environmental: Ongoing asbestos-related litigation (approx. 795 claims pending) and environmental remediation obligations.
Investor Verification Checklist
- Segment Reorganization: Verify the impact of the January 1, 2026, segment restructuring on future comparability of Flow and Water Solutions results.
- Intangible Asset Impairment: Review the $30.9 million impairment charge in Water Solutions and the rationale for the business exit.
- Tax Rate Sustainability: Assess the long-term impact of OECD Pillar Two rules on the effective tax rate, which rose to 14.1% in 2025.
- Customer Concentration: Monitor the 18% sales concentration in the Pool segment and potential risks associated with this single customer.
- Acquisition Integration: Track the integration progress and financial contribution of the Hydra-Stop acquisition ($292.1M) in the Flow segment.
- Debt Covenants: Confirm compliance with leverage ratios (max 3.75x) given the mix of fixed and variable rate debt.
