Highlights

Delivered net sales of $303.3 million for the third quarter of 2025, reflecting a 4.0% decrease from the third quarter of 2024, or a 5.4% organic decline. The year-over-year decline was driven by volume decreases across most geographies, particularly in North America, as we lapped a $33.0 million backlog reduction. The decline was partly offset by price realization. Order rates rose 2.0% compared to the third quarter of 2024, reflecting continued customer confidence in the value and reliability of our solutions.
Achieved Adjusted EBITDA^(a) of $49.8 million, representing an increase of $1.9 million compared to the third quarter of 2024. Adjusted EBITDA^(a) margin of 16.4% increased 120 basis points, driven by gross margin expansion coupled with selling and administrative ("S&A") leverage.
Announced a 5.1% increase in the Company's quarterly cash dividend to $0.31 per share, marking the 54th consecutive year the Company has increased its annual cash dividend payout.
Announced the launch of the T360 walk-behind scrubber as the latest addition to our mid-tier growth strategy. The T360 delivers solid cleaning performance at an economical price point ideal for tight customer budgets and simple, intuitive operation helpful to onboarding first-time users.
Reaffirming our 2025 net sales, Adjusted EBITDA, and EPS guidance based on business outlook for the fourth quarter as we continue to manage in a dynamic demand environment amid significant macroeconomic uncertainties.

"We are pleased to report third quarter results that demonstrate the resilience of our business model even as we navigate an increasingly complex and uncertain market environment," said Dave Huml, Tennant President and Chief Executive Officer. "Net sales of $303 million reflected expected headwinds from lapping last year's significant backlog reduction, resulting in a 5.4% organic decline. We generated 2% year-over-year order growth, expanded gross margins by 30 bps despite tariff-driven inflationary headwinds, and prudently managed S&A expenses to grow adjusted EBITDA^(a)margins to 16.4%, a 120-basis-point increase. Underlying business performance remains stable, though customer demand softened in some sectors, notably in North American industrial amid ongoing tariff uncertainty. We remain focused and committed to executing our enterprise growth strategies, mitigating actions to offset tariff-driven inflation, managing to customer demand dynamics and controlling for S&A expenses accordingly."

Net Sales

Consolidated net sales for the third quarter of 2025 totaled $303.3 million, a 4.0% decrease compared to consolidated net sales of $315.8 million in the third quarter of 2024. The components of the consolidated net sales change were as follows:

	Three Months Ended September 30,	Nine Months Ended September 30,
	2025 vs. 2024
Price	2.8%	1.5%
Volume	(8.2)%	(6.4)%
Organic decline	(5.4)%	(4.9)%
Acquisitions	—%	0.1%
Foreign currency	1.4%	—%
Total	(4.0)%	(4.8)%

Organic Sales

Organic sales, which exclude the effects of foreign currency and acquisitions, decreased 5.4% in the third quarter compared to the prior year. This decrease was driven by volume declines across geographies, partly offset by price realization.

	Three Months Ended September 30, 2025				Nine Months Ended September 30, 2025
	Americas	EMEA	APAC	Total	Americas	EMEA	APAC	Total
Organic sales decline	(7.0)%	(0.4)%	(6.4)%	(5.4)%	(6.4)%	(0.4)%	(6.3)%	(4.9)%

Americas^(b): The 7.0% decrease in the third quarter was primarily driven by volume declines in North America, a result of lapping a significant backlog-reduction benefit in the prior-year period. This was partly offset by price realization.

EMEA^(c): The 0.4% decrease in the third quarter reflected mixed regional performance with volume declines in certain markets partly offset by strong performance in the UK and southern Europe, and price realization.

APAC^(d): The 6.4% decrease in the third quarter was primarily due to decreased commercial equipment volume in China and industrial equipment volume in South Korea.

Operating Results

The gross profit margin of 42.7% in the third quarter of 2025 was 30 basis points higher compared to the third quarter of 2024. The margin rate improved primarily due to strong price realization from strategic pricing actions, supplemented by additional tariff-related pricing adjustments. This was partially offset by lower productivity due to volume decreases.

S&A expense totaled $96.6 million in the third quarter of 2025, a $3.9 million increase compared to the third quarter of 2024. The increase in S&A expense was primarily driven by $5.3 million of legal contingency costs related to an intellectual property dispute, $6.7 million associated with our strategic investments, and $1.3 million in restructuring costs. The increase was partially offset by cost savings realized through lower variable compensation and reduced payroll expense following the restructuring actions executed at the end of the prior year. When excluding non-GAAP costs, Adjusted S&A^(a) as a percentage of net sales decreased to 27.5% in the third quarter of 2025, compared to 28.1% in the third quarter of 2024.

Adjusted EBITDA^(a) was $49.8 million in the third quarter of 2025, compared to $47.9 million in the prior-year period. The increase in Adjusted EBITDA^(a) was primarily due to gross margin expansion coupled with S&A leverage. Adjusted EBITDA margin^(a) for the third quarter of 2025 was 16.4%, up 120 basis points compared to 15.2% in the prior-year period.

Net income was $14.9 million in the third quarter of 2025, compared to $20.8 million in the third quarter of 2024. Adjusted net income^(a) was $27.3 million in the third quarter of 2025, an increase of $0.7 million compared to the third quarter of 2024. The increase was primarily driven by strong operating performance from gross margin expansion coupled with S&A leverage.

Adjusted diluted EPS^(a) was $1.46 in the third quarter of 2025, compared to $1.39 in the third quarter of 2024. The increase was driven equally by improved operating performance and share accretion.

Cash Flow, Liquidity and Capital Allocation

Tennant generated $28.7 million of cash flow for operating activities during the third quarter of 2025, a $2.0 million decrease compared to the prior-year period. Operating cash flow in the third quarter of 2025 was impacted by investments in our ERP project as well as working capital investments and lower operating performance. Tennant generated free cash flow^(a) of $22.3 million in the third quarter of 2025, which included investments in our ERP project of $14.0 million. When excluding ERP investments, the Company converted 183.3% of net income to free cash flow in the third quarter of 2025.

Liquidity remained strong with a balance of $99.4 million in cash and cash equivalents at the end of the third quarter, and $409.3 million of unused borrowing capacity under the Company's revolving credit facility.

The Company continues to strategically deploy cash flow to meet operational capital requirements and to return capital to shareholders in alignment with its capital allocation priorities. During the third quarter of 2025, the Company invested $6.4 million in capital expenditures and returned $28.0 million to shareholders through dividends and share repurchases. The Company remains diligent in managing its debt and maintaining a strong balance sheet. The Company's net leverage ratio was 0.69 times Adjusted EBITDA.^(a)(e)

2025 Guidance

As we enter the final quarter of 2025, we continue to face macroeconomic volatility and escalating tariff pressures. While tariff impacts are expected to increase modestly compared to mid-year estimates, our strategic initiatives position us to substantially neutralize tariff-driven inflation. Despite demand softness in the third quarter, particularly within industrial sales in the Americas, we remain well-positioned to deliver full-year net sales within our $1.210 billion to $1.250 billion guidance, buoyed by strong fourth-quarter momentum, strategic account expansion, and breakthrough products including the Z50 Citadel™ Outdoor Sweeper and X6 ROVR. It is important to note that while we expect to meet our overall net sales target, we now project organic growth to be marginally below our (1)% to (4)% guidance,, as a more significant contribution from favorable foreign currency movements is expected to offset increased pressure on organic net sales.

Rigorous cost management across gross margin and S&A will underpin our path to Adjusted EBITDA of $196 million to $209 million, with expectations toward the lower end of this range. While the fourth quarter will deliver sequential and year-over-year margin improvement, the margin headwinds absorbed in the first half create a structural headwind to full-year expansion.

(In millions, except per share data)	2025 Guidance Ranges
Net sales	$1,210 - $1,250
Organic net sales decline	(3.0)% - (5.0)%
Diluted net income per share	$3.80 - $4.30
