Disclaimer
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 “expect,” “look forward to,” “anticipate,” “intend,” “plan,” “believe,”
“seek,” “estimate,” “will,” “project” or words of similar meaning. We may also
make forward-looking statements in other reports, in presentations, in material
delivered to shareholders 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, of which many are beyond
Siemens’ control. These are subject to a number of risks, uncertainties and
factors, including, but not limited to those described in disclosures, in particular in
the chapter Risks in the Annual Report.
Should one or more of these risks or uncertainties materialize, or should
underlying expectations not occur or assumptions prove incorrect, actual results,
performance or achievements of Siemens may (negatively or positively) vary
materially from those described explicitly or implicitly in the relevant forward-
looking statement.
Siemens neither intends, nor assumes any obligation, to update or revise these
forward-looking statements in light of developments which differ from those
anticipated.
This document includes – in the applicable financial reporting framework not
clearly defined – supplemental financial measures that are or may be alternative
performance measures (non-GAAP-measures). These supplemental financial
measures should not be viewed in isolation or as alternatives to measures of
Siemens’ net assets and financial positions or results of operations as presented
in accordance with the applicable financial reporting framework in its
Consolidated Financial Statements. Other companies that report or describe
similarly titled alternative performance measures may calculate them differently.
Due to rounding, numbers presented throughout this and other documents may
not add up precisely to the totals provided and percentages may not precisely
reflect the absolute figures.

Cyber Security Challenges & Needs
Energy SecurityKeeping Critical Infrastructure Safe & Secure
• Previously stand-alone assets are increasingly connected to the outside world, which
improves efficiency but may open the door to external attacks.
• Risk management is vital. Having credible policies for security, continuity and performance
auditing systems can make the difference between competitive edge
and competitive failure.
• Power assets are classified as national critical infrastructure, leading to tighter regulatory
scrutiny and rising compliance standards
• Power generation companies need to invest in high performing cyber security solutions to
survive and prosper in a more connected and competitive world.

• At the same time, the stability of a converter dominated transmission system is challenging.
The frequency and voltage control as well as fault ride through capability can require
installation of new additional equipment for stable and safe grid operation.
• Need for reactive power compensation
• Need for storage and flexible load peak units
• Increased demand on ancillary grid services and flexible dispatchable load

➢ Lack of physical inertia
➢ Need for reactive power compensation
➢ Need for storage and flexible load peak units

What is the hesitance to use synchronous rotating
equipment long term?
Back-up power & ancillary services✓ CO2 emissions
✓ Operational cost
✓ Maintenance effort
✓ Efficiency, operational
losses in kW
✓ Foot print, landscape
consumption
✓ Reliability & Safety
Rotating grid stabilization equipment is emission-free, even in a configuration
with a GT, if operated by synthetic fuel, e.g. hydrogen
Advanced state of the art rotating products are characterized by unstaffed
operation and very low supervision effort
Electrical synchronous machines, fly wheels are almost maintenance free
products with very long life time, unmanned operation , digital twin approach
Handicap due to rotational ventilation losses. Purposeful design can minimize
the impact. The handicap is questionable considering the excess energy
production periods by renewables
Size ratio significantly better compared to several inverter based configurations,
e.g. HV-DC link converters
Decades of experience with reliable and safe operation of rotating equipment
Rotating equipment provides the basis for reliable and safe system integration
of converter based units with commercial benefit
