McCormick & Company has chosen the London Stock Exchange for a secondary listing of the combined company it is forming through its merger with Unilever's Foods business. The company will keep its primary listing on the New York Stock Exchange. McCormick confirmed the London listing on July 23, 2026, with the listing expected to take effect when the deal closes (StreetInsider; TradingView).

The announcement follows a multi-month deal timeline. Unilever confirmed receiving an offer from McCormick on March 20, 2026, disclosed advanced discussions on March 30, and signed a binding agreement on March 31 (London Stock Exchange; London Stock Exchange; London Stock Exchange). Unilever's regulatory filings had referenced both the London Stock Exchange and Euronext Amsterdam as potential listing venues, as documented in Form 425 filings hosted on McCormick's IR site dated April 1 and June 2, 2026 (McCormick IR; McCormick IR).

The ownership split defines the deal's structure. When the transaction closes, Unilever shareholders are expected to own 55.1% of the combined company, while McCormick shareholders will hold 35.0% (McCormick IR). India and certain other geographies are excluded from the deal, a detail confirmed in McCormick's second-quarter 2026 financial release (McCormick IR).

The deal still requires McCormick shareholder approval and the necessary regulatory clearances, with an expected close by mid-2027 (London Stock Exchange). McCormick had previously said it would announce the secondary listing location by the end of July 2026, a timeline met with the July 23 disclosure (McCormick IR).

The broader context here is why a London listing makes structural sense for this particular deal. Unilever Foods comes with deep European distribution roots, and a secondary listing on the LSE gives Unilever's existing shareholder base a familiar trading venue after the merger. With Unilever shareholders set to own the majority of the combined company, keeping a London listing path is a way to retain those investors rather than forcing them to sell their shares or move to a US-listed security.

The ownership math explains the listing decision. A combined company where the seller's shareholders hold 55.1% and the buyer's hold 35.0% creates a different governance and trading dynamic than a standard acquisition. The LSE listing gives Unilever's institutional investors continued access to trade the stock without having to convert into a US-listed share. Whether this structure adds trading liquidity or splits volume across two exchanges is an open question that will depend on index inclusion, depositary receipt arrangements (instruments that let investors buy foreign stocks through a local intermediary), and the depth of demand on each exchange.

The exclusion of India and certain other markets from the deal is a meaningful detail for anyone modeling the combined company's financials. Carving out markets with different regulatory regimes or joint-venture structures lowers the complexity of integrating the two businesses. But it also narrows the revenue base of what McCormick is acquiring. Investors calculating the combined company's future revenue and EBITDA (earnings before interest, taxes, depreciation, and amortization) will need to adjust for the carve-out rather than using Unilever's reported Foods segment figures as-is.

The mid-2027 close timeline leaves a wide regulatory runway. McCormick shareholder approval is a procedural step that is typically straightforward given the ownership structure, though not automatic. More significant are the antitrust and competition reviews across multiple jurisdictions, given the overlap between McCormick and Unilever Foods in packaged foods and condiments. The geographic carve-out of India and other markets may partly be a pre-emptive move to reduce regulatory friction, though the filings do not detail the specific rationale.

For market participants, the immediate practical question is how the dual-listing structure will work. McCormick's NYSE listing remains the primary one, and the LSE listing is secondary, meaning it will not carry the same reporting primacy or potential index weighting as a primary LSE listing. The combined company's operating model and executive team, disclosed alongside the listing location on July 23, will govern how the two businesses integrate day to day. The listing structure, separately, governs where capital flows and how shareholders exercise their rights. Both deserve scrutiny as the deal moves toward close.
