German tank gearbox maker Renk returned to the Frankfurt Stock Exchange on Wednesday, highlighting growing investor appetite for the defense industry in the wake of Russia’s war in Ukraine.
Shares in the Augsburg-based company traded at 17.50 euros ($19) at the opening, well above the IPO price of 15 euros that valued Renk at over 1.5 billion euros.
Most of the company’s contracts are in the defense sector, where order books are currently overflowing. But Renk’s products also include components for the hydrogen and heat pump sectors, considered crucial to the shift towards green energy.
