ANNUAL REPORT

Form 10-K

(Pursuant to Securities Exchange Act of 1934)

PART I

Part I is included in the Tennant Company 2002 Annual Report to Shareholders (to the extent specific pages are referred to on the Cross Reference Sheet) and is incorporated in this Form 10-K Annual Report by reference, except Item 3 — “Legal Proceedings,” of which there were no material legal proceedings pending, and Item 4 — “Submission of Matters to a Vote of Security Holders” during the fourth quarter, of which there were none.

ITEM 1 — Business

General Development of Business

Tennant Company, a Minnesota corporation incorporated in 1909, is a world leader in designing, manufacturing and marketing products that help create a cleaner, safer world. The Company’s floor maintenance equipment, outdoor cleaning equipment, coatings and related products are used to clean factories, office buildings, parking lots and streets, airports, hospitals, schools, warehouses, shopping centers and more. Customers include the building service contract cleaners to whom organizations now outsource facilities maintenance, as well as user corporations, health care facilities, schools and federal, state and local governments who handle facilities maintenance themselves. We reach these customers through the industry’s largest direct sales and service organization and through a strong and well-supported network of authorized distributors worldwide.

Tennant’s shares are traded on the New York Stock Exchange (NYSE) under the symbol TNC.

Industry Segments, Foreign and Domestic Operations and Export Sales

The Company, as described under “General Development of Business,” has one business segment. The Company sells its products domestically and internationally. Financial information on the Company’s geographic areas is provided on page 27, segment reporting, of the 2002 Annual Report to Shareholders. Nearly all of the Company’s foreign investment in assets reside within Australia, Canada, Japan, Spain, the Netherlands, the United Kingdom, France, and Germany. While subject to increases or decreases in value over time due to foreign exchange rate movements, we believe that these investments are a low business risk.

Principal Products, Markets and Distribution

Products consisting mainly of motorized cleaning equipment and related products, including floor coating and preservation products, are sold through a direct sales organization and independent distributors in North America, primarily through a direct sales organization in Australia, France, Spain, the Netherlands, Germany, and the United Kingdom, and through independent distributors in more than 50 foreign countries. Additional information pertaining to products is included on pages 2 and 3 of the 2002 Annual Report to Shareholders. Tennant is headquartered in Minneapolis, Minnesota, and also has manufacturing operations in Holland, Michigan and Uden, the Netherlands.

Raw Materials and Purchased Components

The Company has not experienced any significant or unusual problems in the purchase of raw materials or other product components and is not disproportionately dependent upon any single source or supply. The Company has some sole-source vendors for certain components, primarily for automotive and plastic parts. A disruption in supply from such vendors may cause a short-term disruption in the Company’s operations. However, the Company believes that it can find alternate sources in the event there is a disruption in supply from such vendors.

Patents and Trademarks

The Company applies for and is granted United States and foreign patents and trademarks in the ordinary course of business, no one of which is of material importance in relation to the business as a whole.

Seasonality

Although the Company’s business is not seasonal in the traditional sense, historically revenues and earnings have been more concentrated in the fourth quarter of each year reflecting the tendency of customers to increase capital spending during such quarter, and the Company’s efforts to close orders and reduce order backlogs.

Major Customers

The Company sells its products to a wide variety of customers, no one of which is of material importance in relation to the business as a whole.

Backlog

The Company routinely fills orders within 30 days on average. Consequently, order backlogs are generally not indicative of future sales levels.

Competition

While there is no industry association or industry data, the Company believes, through its own market research, that it is a world-leading manufacturer of floor maintenance equipment. Active competition exists in most geographic areas; however, it tends to originate from different sources in each area, and the Company believes its market share exceeds that of the leading competitor in many areas. The Company competes primarily on the basis of offering a broad line of high-quality, innovative products supported by an extensive sales/service network in major markets.

Product Research and Development

The Company believes that it regularly commits an above-average amount of resources to product research and development. In 2002, 2001 and 2000, respectively, the Company spent $16,331,000, $16,578,000 and $15,466,000 on research and development activities relating to the development of new products or improvements of existing products or manufacturing processes.

Environmental Protection

Compliance with federal, state and local provisions regulating the discharge of materials into the environment, or otherwise relating to the protection of the environment, has not had, and is not expected to have, a material effect upon the Company’s capital expenditures, earnings or competitive position.

Employment

The Company employed 2,380 persons in worldwide operations as of December 31, 2002.

Access to Information on the Company’s Website

The Company makes available free of charge, through the Company’s website, its annual reports on Form 10-K, quarterly reports on Form 10-Q, and current reports on Form 8-K, and any amendments to those reports filed or furnished pursuant to Section 13(a) or Section 15(d) of the Exchange Act as soon as reasonably practicable after such reports are filed with, or furnished to, the SEC.

ITEM 2 — Properties

The Company’s corporate offices are owned by the Company and are located in the Minneapolis, Minnesota metropolitan area. Manufacturing facilities are located in Minnesota, Michigan and the Netherlands. Sales offices, warehouse and storage facilities are leased in various locations in North America, Europe, Japan, and Australia. The Company’s facilities are in good operating condition, suitable for their respective uses and adequate for current needs. Further information regarding the Company’s property and lease commitments is included on pages 21, 24 and 25 of the 2002 Annual Report to Shareholders Notes to Consolidated Financial Statements.

ITEM 3 — Legal Proceedings

There are no material pending legal proceedings other than ordinary routine litigation incidental to the Company’s business.

ITEM 4 — Submission of Matters to a Vote of Security Holders

No matters were submitted to a vote of security holders during the fourth quarter of 2002.

PART II

Part II is included in the Tennant Company 2002 Annual Report to Shareholders (to the extent specific pages are referred to on the Cross Reference Sheet) and is incorporated in this Form 10-K Annual Report by reference, except Item 9, “Changes in and Disagreements with Accountants on Accounting and Financial Disclosure,” of which there were none.
