ABB, the Swiss industrial group, agrees to acquire Rotork, a UK-listed engineering company, in a deal valued at £4.1 billion, according to multiple reports. The acquisition is described as ABB’s largest ever, with one source also citing a corresponding figure of $5.5 billion. The transaction expands ABB’s automation-related offerings by bringing Rotork’s engineering capabilities into the group. Reporting also notes that the deal involves removing Rotork from the London Stock Exchange, following ABB’s agreement to buy the company outright. The coverage frames the transaction as part of a broader pattern of increased foreign interest in London-listed businesses, with the purchase adding to a series of similar cross-border takeovers. Other mentions in the circulation of headlines include live-market commentary ahead of a scheduled takeover. Across outlets, the central elements remain consistent: ABB is buying Rotork, the announced price is £4.1 billion, and the deal is positioned as a major step for ABB’s automation strategy.
