Performance Amidst Market Crosscurrents

A. O. Smith's recent financial performance reflects the impact of varying market conditions across its segments. In the first quarter of 2025, consolidated net sales decreased by 2% year-over-year to $963.9 million. This decline was primarily driven by lower residential and commercial water heater volumes in North America, partly attributable to a tough comparison against Q1 2024 which benefited from pre-buy ahead of a price increase, and continued softness in China. However, these headwinds were partially offset by strong growth in North America boiler sales (up 10%) and the incremental contribution from the Pureit acquisition in the Rest of World segment ($12 million in Q1 2025).

Profitability in Q1 2025 saw a slight dip in gross profit margin to 38.9% from 39.3% in the prior year, mainly due to lower volumes. North America segment earnings decreased 7% with margins contracting by 120 basis points to 24.7%, impacted by lower water heater volumes, reduced volume-related absorption, and ongoing strategic investments. Conversely, the Rest of World segment demonstrated resilience, with sales essentially flat but segment earnings increasing 15% and margins expanding by 110 basis points to 8.7%. This margin improvement was primarily driven by cost control measures and the benefits of restructuring actions initiated in Q4 2024, which helped offset the impact of lower volumes in China. The Pureit acquisition is expected to be a near-term margin headwind in the Rest of World segment as integration efforts are prioritized.

Looking back at the full year 2024, sales decreased 1% to $3.8 billion compared to a record 2023. Adjusted EPS for 2024 was $3.73, a 2% decrease from 2023, reflecting the impact of lower sales and restructuring expenses ($17.6 million recognized in 2024). The North America segment saw a slight sales increase in 2024, but adjusted earnings and margins decreased due to lower water heater volumes and strategic investments. The Rest of World segment experienced a more significant decrease in adjusted earnings and margins in 2024, primarily due to the challenging market conditions in China, where local currency sales decreased 6%.

Despite the top-line pressures, A. O. Smith has maintained solid cash flow generation. Cash provided by operating activities in Q1 2025 was $38.7 million, lower than Q1 2024 ($106.6 million), primarily due to lower receivables collections and earnings, but Q1 is typically the lowest cash quarter. For the full year 2024, operating cash flow was $581.8 million, resulting in free cash flow of $473.8 million (89% conversion, or 95% excluding higher CapEx), lower than 2023 but still robust. The company's balance sheet remains strong, with a leverage ratio of 12.7% at March 31, 2025, up from 9.3% at the end of 2024 due to increased debt funding share repurchases, but well within covenant limits.

Strategic Responses and Future Outlook

A. O. Smith is actively implementing strategic initiatives to navigate the current market environment and position itself for future growth. In China, where consumer demand softness is expected to persist, the company is undertaking restructuring to optimize its cost structure and align with lower volumes, aiming for approximately $15 million in annual savings upon substantial completion by the end of Q2 2025. This is expected to support China operating margins in the 8% to 10% range in 2025, even with projected local currency sales decreasing 5% to 8%.

In North America, the company is addressing market dynamics by focusing on operational efficiency, including efforts to level load production to avoid the volatility seen in 2024. The North America water treatment business is undergoing a strategic realignment, intentionally shifting focus away from the less profitable retail channel towards dealer, direct-to-consumer, and e-commerce channels. While this is expected to result in a sales decrease of approximately 5% for the NA water treatment business in 2025 ($235-$245 million projected sales), it is anticipated to drive a significant operating margin expansion of approximately 250 basis points for that segment.

The volatile tariff environment presents a notable risk, with management estimating a potential 6% to 8% annual increase in total cost of goods sold based on currently announced tariffs, before mitigation. A. O. Smith is responding with a multi-pronged approach, including announced price increases (averaging 6% to 9% on most North America water heaters, with benefits expected by the end of Q2 2025), strategic sourcing, footprint optimization, and accelerating the transition of gas tankless production to Mexico. Management is confident that these actions will offset the impact of currently announced tariffs and has factored this into its earnings outlook.

For 2025, A. O. Smith projects consolidated sales to be approximately flat to up 2% compared to 2024. This outlook is based on expected flat industry residential and commercial water heater volumes in North America and the projected sales decrease in China, partially offset by growth in boilers (3-5%) and the contribution from Pureit ($50 million projected annual sales). The company expects full-year earnings per share between $3.60 and $3.90, with the midpoint slightly higher than 2024 adjusted EPS. This guidance assumes steel and other input costs (excluding tariffs) are similar to 2024, with steel increasing in the second half. North America segment margin is projected between 24% and 24.5%, and Rest of World segment margin between 8% and 9%.

A. O. Smith's strong balance sheet and expected free cash flow generation ($500-$550 million in 2025) provide flexibility for continued capital allocation. The company has a long track record of returning value to shareholders, having increased its dividend for over 32 consecutive years and returning nearly $1 billion through dividends and buybacks over the last two years. For 2025, the company plans to repurchase approximately $400 million of its shares, front-loading purchases in Q1 based on management's view that the shares were undervalued. The company also maintains an active acquisition pipeline, seeking opportunities that meet its financial metrics and expand shareholder value, as demonstrated by the Pureit acquisition which significantly enhanced its position in the attractive India water treatment market.

Conclusion

A. O. Smith Corporation stands as a resilient global leader in the water technology space, grounded in a long history and a stable core business driven by replacement demand. While facing near-term headwinds from a challenging macro environment, particularly in China, and volume softness in North America water heaters, the company is actively leveraging its technological strengths, strategic investments, and operational discipline to navigate these pressures.

The focus on high-efficiency products, the expansion into growing categories like heat pumps and tankless water heaters supported by significant capacity and R&D investments, and strategic acquisitions like Pureit are positioning A. O. Smith for long-term profitable growth. The company's ability to implement cost control measures and restructuring actions, coupled with planned pricing adjustments, provides confidence in its ability to offset potential tariff impacts and maintain profitability. With a strong balance sheet and robust free cash flow generation supporting continued dividends and share repurchases, A. O. Smith appears well-equipped to weather current market volatility and capitalize on future opportunities in the essential global markets for heating and treating water. Investors should monitor the execution of restructuring plans, the impact of tariff mitigation efforts, and the pace of recovery in the China market as key indicators for the company's performance against its 2025 outlook and beyond.
