Prometheus Energy, an alternative and renewable energy company backed by US buyout group Denham Capital Management, is planning to delist itself from London’s junior Alternative Investment Market to attract private equity funding, following a 95% drop in its market capitalisation since listing less than two years ago.

Prometheus said it had been in discussions with a number of parties to secure funding and that “every party” it spoke with said the “maintenance of the Aim listing is an impediment to them making an investment.”
