The UK Competition & Markets Authority (CMA) launched a Phase 1 investigation into McCormick & Co.’s merger with Unilever PLC’s food business on Wednesday.
The regulator is evaluating the deal valued at approximately £33.8 billion.
Officials are assessing whether the transaction significantly reduces competition within the United Kingdom.
The merger unites McCormick’s French’s mustard with Unilever’s Knorr and Hellmann’s brands to create a global condiments leader.
The CMA established a November 11, 2026 deadline for its preliminary decision.
Unilever shares declined in London early Wednesday following the announcement.
