Background: Chemist Warehouse launched in Australia in 2000 with a model that flipped the script on pharmacies. It entered the game with a new idea: sell more than prescriptions. We're talking discounted vitamins, cosmetics, and fragrances. Today, it has 500 stores, 20,000 staff, and fills around 1.5 million prescriptions weekly, with a $34 billion mega-merger with Sigma Healthcare further scaling its reach.

What happened: The group recently opened nine stores in New Zealand….17 in Ireland… and sells online in Dubai and China. So, the next step? Expanding into the UK by acquiring a 75% interest in Greenlight Healthcare, a 22-store pharmacy chain in London.

What else: While Sigma is ultra-profitable... Greenlight has been loss-making, posting a $2.1 million AUD pre-tax loss in 2024 and seeking external investors. So, rather than building from scratch, Sigma is licensing the Chemist Warehouse brand across Greenlight stores. Chemist Warehouse branding upfront... Greenlight operations underneath.

What's the key learning?

💡Starting a business overseas from zero is one of the hardest things a company can do... but licensing your brand to someone who already exists? That's a very different game.

💡Brand expansion is faster (and cheaper) when you plug into existing networks. Instead of building stores and hiring staff from scratch, Sigma taps into the existing Greenlight pharmacy network, with Chemist Warehouse simply layering its brand on top.

💡Overseas expansion is high risk for Australian retailers. Bunnings' failed UK push cost a $1 billion write-down in 2018, while Smiggle is currently struggling with its international expansion.  Sigma just has to hope the Brits give Chemist Warehouse the green light so that they can keep expanding their brand.
