Shares of Rotork (ROR.L) skyrocketed on Thursday morning after Swiss engineering group ABB (ABBN.SW, ABB.ST) announced a $5.5 billion takeover offer for the British industrial valve actuator manufacturer.
Under the deal, which has the unanimous backing of Rotork's board, ABB is offering 5.03 pounds sterling per share in cash, plus an entitlement to an interim dividend of up to 0.03 pound per share.
Rotork's stock was up 67% in early morning trading in London, while ABB's shares were down 3% in Zürich and Stockholm.
ABB said it will finance the acquisition through existing cash and committed bank facilities, with expected net proceeds of $4.8 billion from the sale of its robotics business to SoftBank expected to mitigate the cash outflow.
Completion is expected in the first half of 2027, subject to the approval of Rotork's shareholders and regulatory clearances. Rotork, which would operate as a separate division under a strategic growth mandate within ABB's automation business area, is expected to be 3% accretive to ABB's revenue.
"ABB has followed Rotork over many years...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," ABB Chief Executive Morten Wierod said.
Separately, ABB the same day reported higher first-half net income and revenue. Attributable net income for the six months ended June 30 grew to $2.56 billion from $2.25 billion a year earlier, while revenue amounted to $18.21 billion, compared with $15.68 billion earlier.
