Swedish-Swiss multinational company
ABB Ltd is a global leader in electrification, robotics, motion, and process automation, with roughly USD 32 billion in 2024 revenue across four core divisions.
The company was formed in 1988 by merging Sweden's ASEA with Switzerland's Brown, Boveri & Cie (BBC) - one of the largest cross-border industrial mergers in European history - and has since operated as a Swiss-Swedish dual-heritage group with its statutory seat and group headquarters in Zurich.
The listed parent ABB Ltd is a Swiss Aktiengesellschaft registered in Canton Zurich, dual-listed on SIX (ABBN) and NYSE (ABB). Previously ABB also carried a Stockholm listing, which was delisted in 2024 to simplify the capital structure; the Stockholm listing had been a legacy of the Swedish ASEA side of the original 1988 merger.
ABB employs roughly 105,000 people globally, with major manufacturing and R&D sites in Zurich, Vasteras (Sweden), Auburn Hills (Michigan), and Ludenscheid (Germany). The Zurich HQ on Affolternstrasse houses group functions, treasury, and IR.
ABB is the canonical example of a Swiss Aktiengesellschaft used as the post-merger vehicle for two predecessor European industrial groups. The 1988 ASEA-BBC merger had to resolve a structural question: where does the combined group domicile? The two options were Sweden (home of ASEA) and Switzerland (home of BBC). Switzerland won for three reasons that still matter for cross-border merger structuring today.
First, Swiss AG governance tolerated a 50/50 initial ownership split between Swedish and Swiss shareholders more cleanly than a Swedish AB structure would have. Swiss corporate law permits bearer and registered share classes, permits cross-shareholdings, and permits a holding company to sit above licensed operating subsidiaries in multiple jurisdictions without triggering entity-level taxation at the holdco.
Sweden offered no comparable clarity in 1988.
Second, Swiss cantonal tax was materially lower than Swedish corporate tax even before TRAF reform. Canton Zurich's combined rate was roughly 20% through the 1990s, compared with Swedish rates in the high-20s to low-30s. The merged group structurally optimised 7-10 percentage points of corporate tax on retained earnings by choosing Zurich.
Third, the Swiss franc's stability and Switzerland's non-EU neutral status gave the merged group balance-sheet optionality that a Stockholm-domiciled parent could not match. ABB could route financing through Swiss-franc debt, report in dollars, and invoice in euros without currency-regime constraints that bound EU-resident industrials.
Legally Swiss since the 1988 ASEA-BBC merger. The parent company ABB Ltd is registered in Canton Zurich and listed on SIX as its primary venue. The Swedish Stockholm listing was delisted in 2024. Operationally the group retains a large Swedish workforce and R&D presence in Vasteras.
Affolternstrasse 44, 8050 Zurich, Canton of Zurich. Group functions, treasury, and IR are all Zurich-based.
The Stockholm listing was a 1988 merger legacy with declining trading volume. Consolidating to SIX plus NYSE simplified the capital structure, reduced compliance cost, and concentrated liquidity in two deeper markets.
ABB sold its Power Grids division to Hitachi in 2020 for roughly USD 11 billion. Hitachi Energy is now independent of ABB, though the two companies maintain commercial relationships.
