Infinis, a waste-to-energy specialist with ambitions to crack into the wind industry, says it bought the 5.6 million Novera shares – or 3.9% of the total – from a single shareholder for £0.75 each. UK law compels Infinis to extend that price to all of Novera’s shareholders.

London-based renewables developer Novera saw its share price rocket 16% on the fresh offer.
