- Resources-company investor Riverstone Energy posted a first-half loss amid falls in the value of holdings including Hammerhead, Centennial and CNOR.

The company booked a net loss for the six months through June of $373.1m.

Its net asset value per share fell 26% to $13.24, or to £10.43 in sterling terms.

'Since the end of last year, Riverstone has announced three new transactions that reflect its focus on diversifying the portfolio and implementing its modified investment approach,' chairman Richard Hayden said.

'The most recent commitment to Aleph Midstream, which is representative of the modified investment approach, provides an opportunity for Riverstone to capitalise on the need for infrastructure in one of the most prolific shale basins outside of North America.'

'We look forward to continuing to evaluate new opportunities and deploying capital in a tactical manner across subsectors to actively manage our portfolio construction.'
