French-German defense giant KNDS said on Wednesday ​it planned to list its shares in Frankfurt ⁠and Paris, in an ⁠initial public offering (IPO) that sources predict would value the maker of ​Leopard 2 tanks and ​Caesar howitzers ⁠at around 15 billion euros ($17 billion).

The offering will consist of 20% of the company’s existing share capital, KNDS said.

Germany will pay more than the IPO price for its 40% stake in the company under a formula that includes a customary control premium and ⁠post-listing ⁠share performance, according to a document seen by Reuters late on Tuesday.

The arrangement is part of Berlin’s effort to preserve parity with the French state following the listing. Parliament’s budget committee is expected to approve the ⁠deal on Friday, according to sources familiar with the matter.

Following the IPO, French state-owned GIAT ​and German state development bank KfW will each ​hold 40% of KNDS’s ordinary share capital and remain long-term ⁠shareholders, ‌the ‌company said.
