MINNEAPOLIS, MN (Aug. 6, 2025)—Tennant Company ("Tennant" or the "Company") (NYSE: TNC) today reported its financial results for the quarter ended June 30, 2025.

•Delivered net sales of $318.6 million for the second quarter of 2025, reflecting a 3.7% decrease from the second quarter of 2024, or a 4.5% organic decline. The year-over-year decline was driven by volume decreases across all geographies, particularly in North America, as we lapped a $26 million backlog-reduction benefit concentrated in higher-margin products in the prior-year period.

•Underlying business fundamentals remain robust with order rates increasing 4.0% compared to the second quarter of 2024, demonstrating continued market demand and customer confidence in our solutions.

•Achieved Adjusted EBITDA(a) of $51.0 million, in line with our expectations, representing a decrease of $7.6 million compared to the second quarter of 2024. Adjusted EBITDA(a) margin of 16.0% decreased 170 basis points, primarily driven by volume declines, due mostly to the challenging comparison against the significant backlog-reduction benefit that enhanced margins in the prior year.

•Returned capital to shareholders through dividends totaling $5.4 million and share repurchases of 179,824 shares for $13.4 million during the quarter.

•Reaffirms its 2025 guidance as we continue to manage macroeconomic uncertainties. We are actively implementing mitigation strategies to address tariff impacts through strategic supply-chain optimization and targeted pricing initiatives.

•Announced the launch of the Z50 Citadel™ Outdoor Sweeper, a market-leading solution purpose-built for industrial and municipal outdoor environments. The Z50 marks Tennant Company's entry into the outdoor sweeping market, unlocking new growth opportunities within our existing and adjacent markets.

"Tennant delivered solid second quarter results that keep us on track to achieve our full-year guidance," said Dave Huml, Tennant President and Chief Executive Officer. "We delivered net sales of $319 million with adjusted EBITDA(a) of $51 million, or 16% of sales. The organic sales decline of 4.5% is driven by the lapping of

a $26 million backlog reduction benefit in the prior year second quarter. Our underlying order demand grew 4% and is our fifth consecutive quarter of order growth at or above long-term targets. The growth in order demand is a direct result of the global team's focused execution of our enterprise growth strategy, and we are clearly building momentum into the second half of 2025. While macroeconomic uncertainty and potential tariff impacts remain variables for the remainder of the year, we remain committed to prioritizing investments that align with our strategic objectives while maintaining spending discipline to deliver sustained profitable growth."

Consolidated net sales for the second quarter of 2025 totaled $318.6 million, a 3.7% decrease compared to consolidated net sales of $331.0 million in the second quarter of 2024. The components of the consolidated net sales change were as follows:

Organic sales, which exclude the effects of foreign currency and acquisitions, decreased 4.5% in the second quarter compared to the prior year. This decrease was driven by volume declines across all geographies, partly offset by price realization.

Americas(b): The 5.5% decrease in the second quarter was primarily driven by volume declines in industrial equipment, particularly in North America, which was lapping a $26 million backlog-reduction benefit in the prior-year period. This was partially offset by price realization and volume increases in commercial equipment.

EMEA(c): The 1.4% decrease in the second quarter was primarily due to volume declines in Germany and the Middle East region, partly offset by volume increases in the UK and Iberia, and price realization.

APAC(d): The 5.0% decrease in the second quarter was primarily due to decreased volumes in China, partly offset by increased equipment volume in Australia.

The gross profit margin of 42.1% in the second quarter of 2025 declined 100 basis points compared to the second quarter of 2024. This decrease was driven by product and customer mix as well as ongoing inflation and lower productivity, partly offset by price realization. The prior-year quarter benefited from a significant backlog, largely consisting of higher-margin industrial products sold through direct channels.

Selling and Administrative ("S&A") expense totaled $93.7 million in the second quarter of 2025, a $0.8 million increase compared to the second quarter of 2024. The increase was primarily driven by higher costs linked to our strategic investments, including Enterprise Resource Planning ("ERP") costs, and a bad debt charge. This increase was partly offset by lower variable compensation and discretionary spending. When excluding non-GAAP costs, Adjusted S&A(a) as a percentage of net sales increased to 27.3% in the second quarter of 2025, compared to 26.4% in the second quarter of 2024. The increase was primarily due to a bad debt charge.

Adjusted EBITDA(a) was $51.0 million in the second quarter of 2025, compared to $58.6 million in the prior-year period. The decrease in Adjusted EBITDA(a) was primarily due to volume declines in net sales and a lower gross margin rate. Adjusted EBITDA margin(a) for the second quarter of 2025 was 16.0%, down 170 basis points compared to 17.7% in the prior-year period.

Net income was $20.2 million in the second quarter of 2025 compared to $27.9 million in the second quarter of 2024. Adjusted net income(a) was $27.8 million in the second quarter of 2025, a decrease of $7.4 million compared to the second quarter of 2024. The decrease was primarily due to lower operating performance mentioned above, partly offset by lower income taxes.

Tennant generated $22.5 million of cash flow for operating activities during the second quarter of 2025, a $3.9 million increase compared to the prior-year period. Operating cash flow in the second 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 $18.7 million in the second quarter of 2025, which included investments in our ERP project of $16.0 million. When excluding ERP investments, the Company converted 137.2% of net income to free cash flow in the second quarter of 2025.

Liquidity remained strong with a balance of $80.1 million in cash and cash equivalents at the end of the second quarter, and $434.3 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 second quarter of 2025, the Company invested $3.8 million in capital expenditures and returned $18.8 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 0.66 times Adjusted EBITDA.(a)(e)

For 2025, Tennant reaffirms the following guidance ranges:
