2. Forward Looking Statements
Our remarks that follow, including answers to your questions and these slides, include statements
that we believe are “forward-looking statements” within the meaning of the Private Securities
Litigation Reform Act of 1995. 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 presentation, 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, especially
given recent turmoil in the credit markets, the level of the Company’s borrowing costs and the
Company’s ability to maintain compliance with financial covenants in its credit agreement; the
cyclical nature of the Company’s access equipment, commercial and fire & emergency markets,
especially during a global economic downturn and credit crisis; the Company’s ability to offset
higher steel and raw material costs through other cost decreases or product selling price increases;
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 associated with international operations and sales, including foreign
currency fluctuations; the Company’s ability to turn around its Geesink business; risks related to the
collectibility of access equipment receivables; and the potential for increased costs relating to
compliance with changes in laws and regulations. Additional information concerning these and other
factors and assumptions is contained in our filings with the SEC, including our Form 8-K filed
November 3, 2008. Except as set forth in such Form 8-K, we disclaim any obligation to update
such forward-looking statements.
