In 2013, I followed people from the company to participate in the sale of Siemens Energy Division to Hitachi Group. The total transaction value is 7.6 billion euros, of which 4.5 billion euros are paid in cash and 3.1 billion euros are assumed as debt. In January 2016, it was announced that the total transaction value of the US software company CD-adapco was US$970 million, because CD-adapco is the world's leading engineering simulation software company, and its software products are widely used in aerospace, automotive, energy, heavy industry and other fields. . CD-adapco’s flagship product STAR-CCM+ is one of the most popular Computational Fluid Dynamics (CFD) software in the world, so we decided to acquire it and in the same year 2016 announced the launch of our company’s medical division, which launched in 2017 Safran Signalise, a French traffic signal lighting company, was listed in July this year, with a total transaction value of 720 million euros. In the same year, the wind power business merged with the Spanish company Gamesa. In November 2016, he assisted the company in acquiring Mentor Graphics, an American electronic design automation (EDA) software company, with a total transaction value of US$4.5 billion. . The transaction was completed in March 2017. Since the digital chemical factory business is one of the company's core businesses, I assisted in operating revenue of 5.9 billion euros and net profit of 1 billion euros in fiscal year 2017. The digital factory business mainly provides software and automation solutions to help customers improve production efficiency and flexibility.
