Milwaukee, Wis.— Global water technology company A. O. Smith Corporation (“the Company”) (NYSE: AOS) today announced its third quarter 2025 results.

Key Financial Metrics

Third Quarter

(in millions, except per share amounts)


	Q3 2025	Q3 2024	% Change YoY
Net sales	$942.5	$902.6	4%
Net earnings	$132.0	$120.1	10%
Diluted earnings per share	$0.94	$0.82	15%

Steve Shafer, chief executive officer, stated, "In the third quarter, the A. O. Smith team achieved sales growth of 4%. The North America segment delivered 6% growth driven by the benefits of pricing actions implemented earlier this year to address increased costs in North America and continued demand resiliency for our commercial water heaters and boilers. This performance was partially offset by continued economic challenges in China, which experienced a 12% local currency sales decline in the quarter."

"I am pleased with the performance of our North America segment on both the top and bottom lines and believe our previously announced strategic assessment of our China business is helping us clarify our path forward for that business," continued Shafer.

Segment-level Performance

North America

Third quarter sales of $742.8 million grew 6% compared to the prior year period primarily due to the benefits of pricing actions as well as higher commercial water heater and boiler volumes.

Segment earnings of $179.7 million in the third quarter of 2025 increased 11% compared to segment earnings of $162.5 million in the third quarter of 2024. Segment operating margin was 24.2%, an expansion of 110 basis points versus the prior-year period. The higher segment earnings and expanded segment operating margin were driven primarily by pricing actions and stronger year-over-year volumes, which more than offset higher material and other input costs.

Rest of World

Rest of World sales of $207.9 million decreased 1% compared to prior year sales of $210.3 million. China sales decreased 12% in local currency year-over-year. Organic sales in India grew 13% in local currency, and Pureit contributed $17 million to sales in the third quarter of 2025.

Segment earnings were $15.4 million, and segment margin was 7.4% in the third quarter of 2025 compared to segment earnings of $13.6 million and segment margin of 6.5%, representing increases of 13% and 90 basis points, respectively, versus the prior-year period. The higher segment earnings and segment margin were primarily a result of the benefits of 2024 restructuring actions and other cost control measures in China, which more than offset the lower China volumes.

Balance Sheet, Liquidity and Capital Allocation

As of September 30, 2025, cash and marketable securities totaled $172.8 million and debt totaled $185.8 million, resulting in a leverage ratio of 9.2% as measured by total debt-to-total capitalization.

Cash provided by operations was $433.7 million and free cash flow was $380.5 million in the first nine months of 2025, both increased compared to 2024, primarily due to lower inventory balances that were partially offset by other working capital outlays including lower customer deposits in China.

As part of its commitment to return capital to shareholders, the Company repurchased 5 million shares at a cost of $335.4 million in the first nine months of 2025. As of September 30, 2025, authority remained to repurchase approximately 1.8 million additional shares. The Company expects to spend approximately $400 million to repurchase shares in 2025.

On October 13, 2025, the Company’s board of directors approved a 6% increase in the dividend rate, resulting in a five-year compound annual dividend growth rate of 7%. The Company has increased its dividend for more than 30 consecutive years.

Outlook

2025 Outlook

(in millions, except per share amounts)


	2024	2025 Outlook
	Actual	Low End	High End
Net sales	$3,818	$3,800	$3,850
Diluted earnings per share	$3.63	$3.70	$3.85
Adjusted earnings per share	$3.731	$3.70	$3.85

1Excludes restructuring and impairment expenses. See accompanying GAAP to Non-GAAP reconciliations

“Our third quarter performance was strong; however we are cautious about the remainder of the year primarily due to continued headwinds in the China market and the impact of weakening new home construction on residential water heating in North America. Therefore, we have lowered our full year 2025 sales outlook to a projection of flat to up 1% compared to last year and lowered the midpoint of our EPS outlook with an anticipated range of $3.70 to $3.85. We remain confident in our ability to manage the tariff and competitive landscapes and are pleased with the performance we achieved in our growth priorities,” Shafer said.

The Company’s guidance excludes the potential impacts from future acquisitions and any potential outcomes of the assessment of its China business. The Company has not set a timetable for completion of this assessment process.

A. O. Smith will host a webcasted conference call at 10:00 a.m. (Eastern Daylight Time) today. The call can be heard live on the Company’s website. An audio replay of the call will be available on the Company’s website after the live event.

To provide improved transparency into the operating results of its business, the Company is providing non-GAAP measures. Free cash flow is defined as cash provided by operations less capital expenditures. Adjusted earnings, adjusted EPS, adjusted segment earnings and adjusted corporate expenses exclude the impact of restructuring and impairment charges.
