This document contains forward-looking statements and information – that is, statements related to future, not past,

events. These statements may be identified either orally or in writing by words as “expects”, “anticipates”, “intends”,

“plans”, “believes”, “seeks”, “estimates”, “will” or words of similar meaning. Such statements are based on our current

expectations and certain assumptions, and are, therefore, subject to certain risks and uncertainties. A variety of factors,

many of which are beyond Siemens’ control, affect its operations, performance, business strategy and results and could

cause the actual results, performance or achievements of Siemens worldwide to be materially different from any future

results, performance or achievements that may be expressed or implied by such forward-looking statements. For us,

particular uncertainties arise, among others, from changes in general economic and business conditions, changes in

currency exchange rates and interest rates, introduction of competing products or technologies by other companies, lack

of acceptance of new products or services by customers targeted by Siemens worldwide, changes in business strategy

and various other factors. More detailed information about certain of these factors is contained in Siemens’ filings with the

SEC, which are available on the Siemens website, www.siemens.com and on the SEC’s website, www.sec.gov. Should

one or more of these risks or uncertainties materialize, or should underlying assumptions prove incorrect, actual results

may vary materially from those described in the relevant forward-looking statement as anticipated, believed, estimated,

expected, intended, planned or projected. Siemens does not intend or assume any obligation to update or revise these

forward-looking statements in light of developments which differ from those anticipated.
