Filing Highlights

Financial Performance

Net sales decreased by 1.27% year-over-year to $1,011.3 million in Q2 2025 and by 1.39% year-over-year to $1,975.2 million for the first six months, primarily driven by lower residential water heater volumes in North America and an 8% decline in China sales, partially offset by recent acquisitions.

Gross profit margin increased to 39.3% in Q2 2025 from 38.7% in Q2 2024, attributed to mix benefits in water treatment. However, net earnings for Q2 2025 decreased by 2.56% year-over-year to $152.2 million, impacted by higher selling, general, and administrative expenses and a significant 155.56% increase in interest expense.

Cash provided by operating activities increased by 8.72% year-over-year to $178.3 million for the first six months of 2025, and free cash flow improved to $139.9 million from $119.1 million in the prior year period. This indicates efficient cash conversion and management of working capital despite the revenue challenges.
