Swiss tech giant makes strategic play to strengthen field-device layer in sweeping all-cash offer
ZURICH: ABB Ltd has announced a blockbuster $5.5 billion acquisition of UK-based Rotork plc, a global leader in intelligent flow control solutions, in a move that significantly bolsters the Swiss automation giant’s position at the critical field-device layer of industrial operations.
The recommended all-cash offer values Rotork at 503 pence per share, representing a striking 60% premium to the company’s three-month average share price. The deal, which values Rotork at approximately 5.3 times its 2025 sales and 19.5 times its 2025 EBITDA, is expected to close in the first half of 2027, a statement said.
A Strategic Marriage of Automation Capabilities
ABB’s acquisition of Rotork represents far more than simple consolidation. The combination unites two companies whose missions are closely aligned around automation and electrification, creating what ABB describes as an enhanced “sense-control-act” automation loop through intelligent field devices and software.
Rotork’s mission-critical flow control and instrumentation solutions — encompassing electric actuators, valve control systems, and monitoring equipment — are highly complementary to ABB’s existing automation portfolio. The company serves segments including oil & gas, chemical, process industries, data centers, water, and power generation.
“ABB has followed Rotork over many years, and we admire the execution excellence, engineering quality, and customer trust that Rotork’s teams deliver each day,” said Morten Wierod, CEO of ABB. “We are convinced of the compelling strategic fit of the transaction that will expand our automation offering at the field device layer, generating significant value for customers, employees, and shareholders of both companies.”
Financial Impact and Synergies
Rotork’s financial performance makes it an attractive target. The company recorded 8% average annual organic revenue growth from 2022 to 2025, with 2025 revenues reaching approximately $1 billion and adjusted operating profit margins of 24.6%.
Upon closing, Rotork is expected to:
· Add approximately 3% to ABB’s total revenues
· Contribute around 12% to ABB’s Automation business area revenues
· Be immediately accretive to ABB’s Operational EBITA margin
· Deliver synergies that reduce the EV/EBITDA multiple toward the “mid-teens” level
Preserving Entrepreneurial Spirit
In a notable move emphasizing its decentralized operating philosophy, ABB intends to operate Rotork as a separate division under a strategic growth mandate within its Automation business area. This approach aligns with ABB’s “ABB Way” model, which prioritizes accountability, transparency, and decision-making speed at the divisional level.
“We’re committed to running Rotork as a separate division,” Wierod added. “This will allow Rotork to accelerate its growth and value creation while preserving its entrepreneurial spirit and customer proximity that makes this business so successful.”
Commitment to UK Operations
ABB has explicitly addressed concerns about Rotork’s UK presence, stating it has “no current plans to significantly change Rotork’s presence in the UK,” which is expected to remain an important manufacturing and technology base. The company already employs over 1,700 people in the UK market.
Dorothy Thompson, Chair of Rotork, endorsed the deal, stating: “The Board believes that the offer from ABB reflects the high quality of Rotork and recognizes the significant progress delivered through the successful implementation of our Growth+ strategy, whilst providing an attractive opportunity for Rotork shareholders to accelerate the value creation of the Company’s strong future prospects, in cash at closing.”
Financing the Deal
ABB will finance the transaction through existing cash resources — the company reported approximately **$5.8 billion in cash and marketable securities** as of June 30, 2026 — as well as committed bank facilities. The deal is further supported by the expected $4.8 billion in net cash proceeds from ABB’s recently signed divestment of its Robotics business to SoftBank, targeted for completion in the second half of 2026.
Deal Timeline and Approvals
The transaction, which will be implemented through a court-sanctioned scheme of arrangement under the UK Companies Act 2006, remains subject to:
· Rotork shareholder approval
· Customary regulatory clearances
The Rotork board has unanimously approved the transaction and will recommend shareholders vote in favor at an upcoming meeting.
Barclays served as sole financial advisor to ABB, with Freshfields providing legal counsel.
