The bosses at Mexican-themed fast-food chain Guzman y Gomez probably had a few celebratory tequilas last night after the company yesterday made the biggest debut on the Australian Stock Exchange (ASX) in 3 years… The company’s valuation topped $3 billion yesterday after it started trading as its share price quickly rose to $30 – $8 more than the issue price. Quite the success story… Guzman y Gomez started in Sydney back in 2006 and has since opened more than 200 stores across the country – as well as Japan, Singapore and the US. If you’re not familiar, they serve things like burritos, nachos, tacos and quesadillas – and they’ve got plans to open 1,000 stores, so you could be saying ‘hola’ soon…
