Enhanced Platform
Blades and Vanes
Improved blade and seal concept provides
highest efficiency.
Optimized seal concept in shape of shroud
and number of fins minimizes leakages
All HP blades utilize well proven
root/clamping design, thus ensuring
reliability
Improved cylindrical and conical HP
blades allow for longer airfoils and
provide most competitive cost
3D optimized HP blades reach highest
efficiency, still allowing simple processes
in sales, engineering, and production due
to predefined sub-components
The integration of all current state of the
art last stage blades provides full
flexibility to meet customer requirements

NOTES AND FORWARD-LOOKING STATEMENTS
This document contains statements related to our future business and financial performance and future events or developments involving Siemens that may
constitute forward-looking statements. These statements may be identified by words such as “expects,” “looks forward to,” “anticipates,” “intends,” “plans,”
“believes,” “seeks,” “estimates,” “will,” “project” or words of similar meaning. We may also make forward-looking statements in other reports, in presentations, in
material delivered to stockholders and in press releases. In addition, our representatives may from time to time make oral forward-looking statements. Such
statements are based on the current expectations and certain assumptions of Siemens’ management, and are, therefore, subject to certain risks and uncertainties.
A variety of factors, many of which are beyond Siemens’ control, affect Siemens’ operations, performance, business strategy and results and could cause the
actual results, performance or achievements of Siemens to be materially different from any future results, performance or achievements that may be expressed or
implied by such forward-looking statements or anticipated on the basis of historical trends. These factors include in particular, but are not limited to, the matters

Further information about risks and uncertainties affecting Siemens is included throughout our most recent annual, and interim reports as well as our most recent
earnings release, which are available on the Siemens website, www.siemens.com, and throughout our most recent annual report on Form 20-F and in our other
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, performance or achievements of Siemens may vary materially from
those described in the relevant forward-looking statement as being expected, anticipated, intended, planned, believed, sought, estimated or projected. Siemens
neither intends, nor assumes any obligation, to update or revise these forward-looking statements in light of developments which differ from those anticipated.
