Mister Spex has postponed its initial public offering. Three years ago, Mister Spex announced that it would go public by the end of this year. Goldman Sachs acquired one-fifth of Mister Spex's shares in January 2015. So far, the German eyewear retailer had collected €80 million from investors and employed more than 450 people. Mister Spex's investors – Goldman, Scottish Equity Partners and Grazia Equity – are apparently ready to go public. In 2017, the company announced that it had recorded total revenues of €100 million. According to ZVA, the German opticians' association, online sales in the eyewear retail industry currently stand at 4.3 percent of total sales. Mister Spex recently opened its tenth brick-and-mortar store in Münster, Germany. The German online retailer already opened two new physical stores near Frankfurt and in Erfurt in April, followed by one in Essen in May. Mister Spex opened its first physical store in Berlin in February 2016, followed by a second one in 2017. Four other brick-and-mortar stores followed in Bremen, Bochum, Dortmund and Oberhausen.
