How a pharmacy chain became a retail giant by rethinking the medicine cabinet

In short: Chemist Warehouse transformed the Australian pharmacy landscape by pivoting from traditional prescriptions to a high-volume, discount-driven model. By leveraging a complex franchise structure and aggressive e-commerce strategies, the company now commands half the market share, though its rapid ascent has frequently sparked friction with industry regulators and labor unions.

The origins of Chemist Warehouse trace back to 1972, when brothers Jack and Sam Gance purchased their first pharmacy in Reservoir, Melbourne. Mario Verrocchi joined as a trainee under Sam Gance in 1980. After leaving the Amcal chain in 1997 to establish My Chemist, the duo founded the Chemist Warehouse brand in 2000. Today, the group operates over 500 stores in Australia and employs more than 20,000 staff, positioning itself as a dominant force in the retail sector.

The company’s business model relies on a sophisticated franchise structure designed to navigate Australian regulations that restrict pharmacy ownership density. By requiring minimal equity from individual pharmacists while enforcing strict group-wide trading terms, the company effectively controls about 400 pharmacies. Unlike traditional pharmacies, the bulk of its revenue stems from non-prescription goods like vitamins, cosmetics, and fragrances. The company also maintains partial ownership of several brands, including Goat Soap and Wagner supplements, and holds a stake in medical vape manufacturer Liber Pharmaceuticals.

International expansion began in 2017 with a New Zealand store, followed by entries into Ireland, China, and the United Arab Emirates. The company’s digital footprint is equally expansive, utilizing platforms like Alibaba’s Tmall Global. During the November 2018 Singles’ Day sale, the brand moved over A$20 million in stock in just seven hours. In February 2025, the company achieved a major corporate milestone by merging with Sigma Healthcare, transitioning into a publicly listed entity on the ASX.

This growth has not been without controversy. The Pharmacy Guild of Australia and labor unions have criticized the company’s impact on healthcare standards and employment conditions. In 2016, the Fair Work Ombudsman ordered the company to back-pay over $3.5 million to nearly 6,000 employees. Additionally, in 2020, the company faced a $53,280 fine for advertising therapeutic goods that had been removed from the Australian Register of Therapeutic Goods. Despite these challenges, the company continues to diversify, recently entering the optometry market and hospital pharmacy sector.
