ClarusONE Sourcing Services LLP is the generic pharmaceutical sourcing venture that McKesson and Walmart established in McKesson's fiscal 2017, and it negotiates with generic drug manufacturers on behalf of both companies so that their combined United States volumes are bought as one book of business. Registered as a limited liability partnership in London, it runs the sourcing tools, demand forecasting and consolidated purchasing that set the terms on which generics reach McKesson's distribution network and Walmart's pharmacies, and it is one of the small group of buying consortia that concentrate most United States generic drug purchasing. McKesson consolidates the partnership in its accounts and reports Walmart's share as a noncontrolling interest.
Source
ClarusONE Sourcing Services LLP files nothing with the SEC, so none of this comes from a filer record. The description was written for this site in August 2026 from McKesson Corporation Form 10-K for the fiscal year ended 31 March 2026 (SEC), ClarusONE Sourcing Services company website and Meet The Power Buyers Driving Generic Drug Deflation (Drug Channels). The ownership figures below come from the holders' filings instead, and are sourced row by row.
The disclosed stakes
One row per position. Where a holder reports the same company in two share classes, both rows are shown rather than summed, because the class is part of a position's identity.
Where each figure comes from
A private stake has no ownership form behind it, so the source is always the holder's own filing or disclosure. Anything modelled says so, with the arithmetic.
- McKesson Corporation. McKesson's ownership percentage in ClarusONE and its individual carrying value are not disclosed. The FY2026 10-K discloses only a combined noncontrolling-interest balance of $395 million at 31 March 2026 and $380 million at 31 March 2025 covering ClarusONE, Vantage Oncology Holdings and SCRI Oncology together; the filing does not split this figure by entity, so no individual value or percentage can be sourced. Recorded unsized rather than omitted because the investee is named and the relationship (McKesson as controlling, consolidating party) is disclosed. source
What this page is not
It is not a complete register. It lists the holders who happen to be inside the researched set and disclosed the stake themselves. A private company can have many other shareholders, and nothing here rules them out: venture investors, founders and employees usually appear in no public filing at all. Percentages are of ClarusONE Sourcing Services LLP where a holder stated one, and are missing where no holder did.
