Anglo American confirms June delisting from the SIX Swiss Exchange ahead of its $53 billion merger with Teck Resources, retaining its primary London listing
Anglo American has announced it will delist its shares from the SIX Swiss Exchange on 26 June 2026, ahead of the completion of its $53 billion merger with Teck Resources. Following the combination, Anglo American intends to maintain its primary listing on the London Stock Exchange, with secondary listings in Johannesburg, Toronto and New York, each subject to the relevant exchange approvals. The Swiss delisting is a structural tidying exercise ahead of a transaction that will create one of the world's largest diversified mining groups. Maintaining London as the primary listing venue is significant: it anchors the combined group to UK Listing Rules, the UK Corporate Governance Code, and FCA continuing obligations — meaning ongoing disclosure, significant transaction, and related party requirements will be governed by the UK regime. For capital markets practitioners, the post-merger listing rationalisation generates a distinct workload: prospectus or circular preparation for the relevant exchanges, delisting notifications, shareholder communications, and coordination with four separate exchanges across three continents. The retention of a London primary listing also preserves access to FTSE index inclusion for the combined entity, which matters for passive fund flows and liquidity.
Why this matters
Retaining London as primary listing venue for a $53 billion combined mining group is commercially significant for the City: it confirms that post-merger listing consolidation continues to favour LSE over competing venues, despite ongoing debate about London's competitiveness. The delisting and relisting exercise activates capital markets, corporate governance, and regulatory advisory work across multiple jurisdictions simultaneously. The 'why now' is straightforward — merger completion requires listing structure rationalisation before the deal closes. For firms advising on the transaction, the multi-exchange coordination work is non-trivial, given differing prospectus equivalence regimes between the UK, Canada and South Africa.
On the Ground
A trainee on this matter would assist with drafting and proofreading shareholder circular and listing application forms for the retained exchanges, prepare PDMR (persons discharging managerial responsibilities) notification letters following any structural changes, and help coordinate the verification note process for any public documents issued in connection with the delisting and re-registration.
Interview prep
Soundbite
Post-merger listing rationalisation at this scale keeps London's primacy debate live — every exchange choice carries index and regulatory consequences.
Question you might get
“What ongoing obligations does a primary LSE-listed company have under the UK Listing Rules following a major merger, and how do those differ from obligations on secondary-listed exchanges?”
Full answer
Anglo American will delist from the Swiss exchange in June ahead of its $53 billion merger with Teck Resources, retaining London as its primary listing venue. For law firms, this activates a multi-exchange workload: delisting notifications, prospectus or circular preparation, and ongoing compliance with UK Listing Rules for the combined group. The wider picture is the sustained debate about whether London can retain large-cap mining and commodity listings against rival venues — Anglo American's choice to anchor to the LSE is a data point in that debate. This suggests that for dual-listed resource companies, London's deep institutional investor base and FTSE index inclusion remain decisive factors even in a complex multi-jurisdictional combination.
