According to insiders, the German battery manufacturer BMZ is planning a listing on the Frankfurt stock exchange in September.
The company from Karlstein could be valued at around two billion euros, said people familiar with the plans to the Reuters news agency.
The banks Citi, JP Morgan and Berenberg prepared the IPO, which could have a volume of around 500 million euros.
BMZ is constantly reviewing its options, said a company spokeswoman on Monday.
The banks did not want to comment.
With the switch to electromobility under the pressure of global climate protection policy, battery manufacturers have good business prospects and are therefore in demand with investors.
BMZ manufactures batteries and battery systems for electric vehicles, from e-bikes to trucks, as well as for forklifts, tools, medical devices and power storage.
The medium-sized company, which employs around 3,000 people at seven locations in Europe, the USA and Asia, made EUR 400 million in sales last year and expects significant growth this year.
The company value could be five times as high as the expected annual turnover, similar to that of the competitor Akasol, said two insiders. BMZ's customers include forklift manufacturer Kion, medical device manufacturer Philips and tool manufacturer Stihl. Founded in 1994, the company was profitable from the start and has increased sales by 20 percent annually over the past ten years.
