- Sycamore Partners, the current owner of Boots, is actively seeking potential buyers for the British pharmacy giant operating more than 1,800 locations

Shares of Sigma Healthcare (SIG) tumbled as much as 5.5% to A$2.76 on Wednesday following the Australian pharmaceutical retailer’s acknowledgment that it has initiated early-stage negotiations to purchase British pharmacy giant Boots.
Sigma Healthcare Limited, SIG.AX
The disclosure was made through an Australian Securities Exchange submission, in which Sigma stated it had “engaged in preliminary discussions in relation to the sale process.” However, the company emphasized that “there is no certainty that any transaction will eventuate.”
According to initial reports from the Financial Times, the potential acquisition could see Boots valued at more than $10 billion. Sigma faces competition in the bidding process, with the Weston family from Canada—majority owners of Loblaw—also pursuing the opportunity.
Sycamore Partners, a United States-based private equity group, currently controls Boots. The pharmacy network maintains over 1,800 retail locations throughout the United Kingdom and extends its operations to 11 nations, including Ireland, Mexico, and Thailand, totaling 3,776 stores as of August last year.
Should the sale proceed, it would terminate Boots’ intentions to pursue a public listing on the London Stock Exchange, the Financial Times confirmed.
Sigma’s pursuit of Boots aligns with the company’s strategic expansion into global territories. In recent weeks, the firm announced a collaboration with UK-based Greenlight Healthcare to establish Chemist Warehouse-branded pharmacies throughout London while providing operational support to Greenlight’s existing 22 stores through supply chain and promotional assistance.
Chemist Warehouse Financial Power
Sigma’s international ambitions are supported by substantial Australian capital. The company’s largest stakeholders include billionaire siblings Jack and Sam Gance, alongside their business associate Mario Verrochi—the founding partners behind the Chemist Warehouse empire.
Verrochi currently maintains a real-time net worth of $5.5 billion. Jack Gance holds wealth totaling $3.4 billion, while Sam Gance’s fortune stands at $3.2 billion, based on Forbes calculations.
Earlier this year in February 2025, Chemist Warehouse completed its combination with Sigma Healthcare through a merger that formed a pharmaceutical conglomerate valued above $22 billion. The unified organization now operates more than 950 retail locations spanning Australia, China, Dubai, Ireland, and New Zealand.
Implications of a Boots Acquisition for Sigma
Acquiring Boots would represent far more than a modest expansion. With approximately 3,800 stores worldwide and franchise agreements extending into the Middle East and Indonesia, such a purchase would fundamentally reshape Sigma’s global footprint.
The pharmaceutical group has not revealed specific financial details regarding its potential offer, nor has it confirmed whether it is collaborating with financing partners to facilitate a transaction of this magnitude.
Wednesday’s market response demonstrates investor uncertainty. A deal surpassing $10 billion would dwarf any previous transaction undertaken by the organization, and the final outcome remains highly uncertain.
Sigma has pledged to provide market updates should any significant progress occur.
