The investigation centers around whether the Company provided inaccurate or deceptive statements and/or neglected to reveal important information that would impact investors. On June 22, 2023, Siemens Energy made public that it had uncovered a significant rise in failure rates of wind turbine components and had taken steps to conduct a comprehensive technical assessment in response. This technical review is projected to incur a cost of 1 billion euros, causing the Company to retract its profit guidance for fiscal year 2023. As a result of this announcement, Siemens Energy shares experienced a 27% decline on the following day.
