Item 2.02. Results of Operations and Financial Condition.

On April 27, 2006, Tennant Company (the “Company”) issued the news release that is attached hereto as Exhibit 99 and incorporated herein by reference.

This news release includes presentations of non-GAAP measures that include or exclude unusual or non-recurring items. For each non-GAAP measure, the news release also provides the most directly comparable GAAP measure and a reconciliation of the non-GAAP measure to the GAAP measure. Management believes that the non-GAAP measures provide useful information to investors regarding the Company’s results of operations and financial condition because they permit a more meaningful comparison and understanding of the Company’s operating performance for the current, past or future periods. Management uses these non-GAAP measures to monitor and evaluate ongoing operating results and trends and to gain an understanding of the comparative operating performance of the Company.
