ERP stabilization held during the quarter, though the expected optimization benets did not fully materialize, with residual ineciencies in North America and continued pricing and volume pressure in EMEA weighing on results. Orders of $339.5 million increased 6.6% year over year, growing across most regions and building backlog to $127 million, reinforcing healthy underlying demand. Net sales of $324.0 million increased 1.7% year over year, reecting price realization and favorable foreign currency eects, partially oset by an organic sales decline driven by softer volumes in EMEA and APAC. Adjusted EBITDA (a) of $35.3 million, or 10.9% of net sales, declined compared to the prior year as gross margin and cost leverage fell short of expectations, driven by residual ERP-related ineciencies in North America and pricing and cost pressure in EMEA. Adjusted diluted EPS (a) of $0.83 declined compared to the prior year, primarily due to lower gross margin rates and higher operating costs, partially oset by the benet of share repurchases. Robotics momentum continued to build, with AMR sales of approximately $31 million increasing 37% year over year, underscoring progress toward the Company's $250 million AMR revenue target by 2028. a) See supplemental non-GAAP nancial tables below for a reconciliation of adjusted non-GAAP nancial measures to GAAP. “Our second quarter results reect solid demand and order growth, though margin recovery progressed more slowly than we expected,” said Dave Huml, Tennant President and Chief Executive Ocer. “Orders grew across most of our regions, robotics revenue grew approximately 37%, and backlog continued to build, underscoring the strength of underlying demand for our products. At the same time, residual ERP-related ineciencies in North America and margin pressure in EMEA weighed on protability more than we anticipated. We are taking targeted actions to address these challenges. Reecting the strength of our order book, backlog, and continued robotics momentum, we are raising our full-year net sales guidance while lowering our full-year Adjusted EBITDA guidance range to reect both the protability impacts experienced in the rst half of the year and a more measured pace of margin recovery in the second half.” Net Sales Consolidated net sales for the second quarter of 2026 totaled $324.0 million, a 1.7% increase compared to consolidated net sales of $318.6 million in the second quarter of 2025. The components of the consolidated net sales change were as follows: 2

This decrease was the result of price realization being more than oset by lower volume, reecting production and fulllment constraints in North America and softer demand in certain EMEA and APAC markets.

Operating Results The gross prot margin of 39.5% in the second quarter of 2026 was 260 basis points lower compared to the second quarter of 2025. The margin rate decline was driven primarily by ERP-related recovery costs, supply constraints, and elevated freight and tari-related material costs in North America. In EMEA, margin was pressured by competitive price concessions, volume deleverage, and unfavorable mix. These impacts were partially oset by price realization and cost management actions. Selling and administrative ("S&A") expense totaled $99.5 million in the second quarter of 2026, a $5.8 million increase compared to the second quarter of 2025. The increase was primarily driven by unfavorable foreign currency, higher people-related costs and technology spend, partially oset by lower bad debt expense and other administrative expenses. S&A expense as a percentage of sales was 30.7% in the second quarter of 2026, compared to 29.4% in the second quarter of 2025. Adjusted S&A(a) as a percentage of net sales increased to 29.1% in the second quarter of 2026, compared to 27.3% in the second quarter of 2025. Research and development ("R&D") expense totaled $12.5 million in the second quarter of 2026, compared to $9.8 million in the second quarter of 2025. The increase was primarily driven by continued investment in innovation, including robotics and autonomous solutions. Adjusted EBITDA(a) was $35.3 million in the second quarter of 2026, compared to $51.0 million in the prior-year period. The decrease in Adjusted EBITDA(a) was primarily due to gross margin declines coupled with S&A deleverage. Adjusted EBITDA margin(a) for the second quarter of 2026 was 10.9%, down 510 basis points compared to 16.0% in the prior-year period. Net income was $7.6 million in the second quarter of 2026, compared to $20.2 million in the second quarter of 2025. Adjusted net income(a) was $14.4 million in the second quarter of 2026, a decrease of $13.4 million compared to the second quarter of 2025. The decrease was primarily driven by lower operating performance from gross margin compression coupled with S&A deleverage. Adjusted diluted EPS(a) was $0.83 in the second quarter of 2026, compared to $1.49 in the second quarter of 2025. The decrease was driven by lower adjusted net income resulting from gross margin compression and S&A deleverage, partially oset by a reduction of approximately 1.5 million diluted weighted average shares outstanding versus the prior-year period. Cash Flow, Liquidity and Capital Allocation Tennant generated $5.0 million of cash ow for operating activities during the second quarter of 2026, a $17.5 4

Page 5

million decrease compared to the prior ‑ year period, primarily driven by lower operating performance and increased working capital requirements, including higher accounts receivable and inventory balances and lower accounts payable. Working capital levels and cash conversion were adversely aected by operational and process ineciencies associated with the North America ERP implementation, and management remains focused on improving working capital eciency as stabilization and fulllment eorts progress. Liquidity remained strong with a balance of $76.9 million in cash and cash equivalents at the end of the second quarter, and $289.4 million of unused borrowing capacity under the Company's revolving credit facility. The Company continues to strategically deploy cash ow to meet operational capital requirements and to return capital to shareholders in alignment with its capital allocation priorities. During the second quarter of 2026, the Company invested $5.3 million in capital expenditures and returned $5.3 million to shareholders through dividends. The Company remains diligent in managing its debt and maintaining a strong balance sheet. The Company had a net leverage ratio (Adjusted Net Debt(a) / trailing twelve months (TTM) Adjusted EBITDA(a)) of 2.0 times as of June 30, 2026. (a) See supplemental non-GAAP nancial tables below for a reconciliation of adjusted non-GAAP nancial measures to GAAP. 2026 Guidance Our rst-half results reect solid demand and order growth, though gross margin recovery progressed more slowly than we anticipated. Residual ERP-related ineciencies in North America, together with pricing and volume pressure in EMEA and incremental freight and material costs tied to Middle East disruptions, weighed on margin performance during the second quarter. Order momentum remained healthy, with orders up 6.6% year over year and backlog building to $127 million, and robotics revenue grew approximately 37% year over year. Based on our rst-half performance and our outlook for the second half, we are raising our full-year net sales guidance, reecting our order and backlog position and continued robotics momentum, while lowering our full-year Adjusted EBITDA guidance range to reect the slower pace of margin recovery, as follows.
