Under the terms of the bid, which has been accepted by John Laing’s board of directors, shareholders will receive 403p per share in cash, a premium of 27 per cent to the closing price on May 5, the day before the company confirmed that it was in takeover talks.

Investors will vote on the offer in early July.

Asset manager Schroders, which owns 8% of John Laing, described as a “fair deal” for investors.

Aberdeen Standard Life, John Laing’s largest investor with a 15% stake, has yet to declare its voting intention.

John Laing’s chair, Will Samuel, said: “KKR is a strong partner, providing long-term capital and global expertise to accelerate John Laing’s strategy, growing the development capacity and assets of John Laing and creating opportunities for our employees and broader stakeholders.

“This is particularly relevant in the current environment where there may be significant opportunities to invest in critical infrastructure which responds to public needs.”

Tara Davies, a partner and co-head of European infrastructure at KKR, said: “There is growing global demand for national infrastructure that delivers societal benefit and reflects technological advances and policy priorities across areas such as connectivity, renewable energy and transport.”
