All statements other than statements of historical fact, including, without limitation, statements regarding the Company’s future financial position, business strategy, targets, projected sales, costs, earnings, capital expenditures, debt levels and cash flows, and plans and objectives of management for future operations, are forward-looking statements. When used in this press release, words such as “may,” “will,” “expect,” “intend,” “estimate,” “anticipate,” “believe,” “should,” “project” or “plan” or the negative thereof or variations thereon or similar terminology are generally intended to identify forward-looking statements. These forward-looking statements are not guarantees of future performance and are subject to risks, uncertainties, assumptions and other factors, some of which are beyond the Company’s control, which could cause actual results to differ materially from those expressed or implied by such forward-looking statements. These factors include the consequences of financial leverage associated with the JLG acquisition, including the level of the Company’s borrowing costs, the increased interest rates the Company would face if it experienced a deterioration or downgrade in credit agency ratings and the Company’s ability to maintain compliance with its financial covenants under its credit agreement; the cyclical nature of the Company’s access equipment, commercial and fire & emergency markets, especially during a global recession and credit crisis; the duration of the global recession, which could lead to additional impairment charges related to many of the Company’s intangible assets; risks related to the required rapid increase in the rate of production for the M-ATV contract and the amount, if any, of additional orders for M-ATVs that the Company may receive; the expected level and timing of U.S. Department of Defense procurement of products and services and funding thereof; risks related to reductions in government expenditures and the uncertainty of government contracts; risks related to production delays as a result of the economy’s impact on the Company’s suppliers; the potential for commodity costs to rise sharply in a future economic recovery; risks associated with international operations and sales, including foreign currency fluctuations; risks related to the collectability of receivables during a recession, particularly for those businesses with exposure to construction markets; and the potential for increased costs relating to compliance with changes in laws and regulations. Additional information concerning these and other factors is contained in the Company’s filings with the Securities and Exchange Commission, including the prospectus supplement for the offering to which this communication relates.
