ABB to Acquire Rotork for $5.5B in Industrial Automation Push

ABB has struck a deal to acquire Rotork, a UK-based provider of intelligent flow control solutions, for approximately $5.5 billion in cash. The transaction will expand ABB's automation portfolio and strengthen its position in the field-device layer of industrial control systems.

Under the agreement, Rotork shareholders will receive 503 pence per share in cash—a roughly 60% premium over the company's three-month average share price. Shareholders will also be entitled to an interim dividend of up to 3 pence per share for the period ending June 30, 2026, according to details first reported by Marine Link.

Strategic fit in automation

Rotork's flow control and instrumentation technology complements ABB's existing automation business by adding intelligent field devices and software used to monitor and manage industrial processes. Following the transaction's completion, Rotork will operate as a separate division within ABB's Automation business area.

The acquisition targets a company that generated around $1 billion in revenue in 2025 with an adjusted operating profit margin of 24.6%. ABB expects the deal to add approximately 3% to its revenues and immediately improve its Operational EBITA margin.

Financing and timeline

ABB will finance the acquisition through existing cash reserves and committed bank facilities. The company noted that its planned sale of its Robotics business to SoftBank—expected to generate about $4.8 billion in net cash proceeds—will further strengthen its liquidity position.

The transaction will be implemented through a court-sanctioned scheme of arrangement under the UK Companies Act. Completion is anticipated in the first half of 2027, pending Rotork shareholder approval and customary regulatory clearances.

Why it matters

This acquisition represents a significant consolidation move in industrial automation, where field-level intelligence is increasingly critical for operational efficiency and sustainability goals. By preserving Rotork as a separate division, ABB aims to maintain the acquired company's entrepreneurial culture while leveraging scale advantages—a model that will be closely watched by other automation consolidators.

"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," said Morten Wierod, ABB's CEO. He added that ABB's strong balance sheet leaves room for additional M&A activity and execution of its announced share buyback program.

Dorothy Thompson, Chair of Rotork, said the combination brings together two companies with aligned purposes focused on automation and electrification to enable more sustainable and efficient operations. Rotork's board has unanimously agreed to recommend the offer to shareholders.
