Birkenstock: Brothers behind shoe brand are worth $3.5 billion

German brothers Alex and Christian Birkenstock, owners of Birkenstock Holding Plc, have become billionaires with a net worth of $3.4 billion after the company’s recent trading debut in New York. Despite a 13% drop in shares, it is still a significant return on their decision to hand over majority control to private equity firm L Catterton in 2021. The brothers received over €3 billion from the transaction, in addition to dividends of €100 million per year in the two years prior.
