Shares of British engineering firm Rotork surged 67% on Thursday after Swiss industrial conglomerate ABB announced a $5.5 billion cash acquisition, the largest in ABB's history. The deal underscores a broader trend of overseas buyers targeting UK-listed companies, with takeover offers exceeding $231 billion so far this year.
ABB's Largest Deal Yet
The recommended cash offer surpasses ABB's previous record acquisitions, including the $4.2 billion purchase of Baldor in 2011 and the $3.9 billion acquisition of Thomas & Betts a year later. ABB plans to finance the deal using proceeds from the planned $4.8 billion sale of its robotics division to SoftBank Group, announced last October.
Rotork specializes in actuators and flow control equipment that automate industrial valves used in oil and gas, power generation, water treatment, chemicals, mining, and marine operations. The company generated roughly $1 billion in revenue in 2025, growing at an annual rate of about 8%, and reported an operating margin of 24.6%.
ABB expects the acquisition to add approximately 3% to group revenue while immediately boosting profitability. "ABB has followed Rotork over many years," said CEO Morten Wierod. "We are convinced of the compelling strategic fit of the transaction that will expand our automation offering at the field device layer."
UK M&A Boom Accelerates
The Rotork deal adds to a growing list of UK-listed companies agreeing to overseas takeover offers, putting Britain on track for its busiest year ever for mergers and acquisitions. Recent bids include those for Intertek, Schroders, Unilever's food business, and Tate & Lyle, which received an offer from US-listed Ingredion in June.
Separately, energy services company DCC said on Thursday it had received an improved proposal from investment firms KKR and Energy Capital Partners, adding up to 125 pence per share in cash to a previous £5.7 billion offer. The bidders have until July 27 to submit a firm offer or walk away.
Foreign buyers account for 86% of the total value of UK mergers and acquisitions in 2026, up from 75% a year earlier, with US companies responsible for more than half of overseas bids. The sustained pace of acquisitions continues to reduce the number of companies listed on the London Stock Exchange as international buyers seek to capitalize on comparatively lower UK valuations.
For context, similar takeover dynamics have driven significant moves in other sectors, as seen in Watches of Switzerland's 138% surge on US growth and takeover speculation.
Strong Earnings Support Acquisition
ABB's takeover announcement coincided with stronger-than-expected second-quarter earnings. Operational EBITA rose 20% year over year to $1.93 billion, ahead of analyst expectations of $1.88 billion. Revenue increased 14% to $9.48 billion, while net income rose 7% to $1.23 billion. Orders climbed 30% to $12.04 billion, driven by continued investment in electrification and automation equipment, particularly for data centers supporting AI workloads.
"Our second-quarter results reflect high demand in the majority of our customer segments," Wierod said. ABB's shares rose about 3% in premarket trading in Zurich following the earnings release and the acquisition announcement.
The broader market has also seen strong earnings from major players, such as JPMorgan's record $21.2B net income in Q2, highlighting the robust demand for financial and industrial services.
