"This is likely to result in Powerhouse pursuing value creation or liquidity events for some portfolio companies to realign the portfolio," it said.
The company reiterated its comments of last week that it is considering an unsolicited offer for some of its shares in one investee company. If that occurred, Powerhouse would "benefit from a substantial immediate cash inflow and a fair value uplift," it said today.
The carrying value of its portfolio of companies fell to $17.5m as at June 30 from $20.7m a year earlier, with the Hydroworks impairment offset by valuation uplifts for its 33 per cent-owned Photonic Innovations and other companies including Syft Technologies (since sold).
Powerhouse said it expects an increase in the value of its portfolio in 2018 and combined with "stringent cost control and the potential for value creation events is expected to result in much stronger earnings in H1 FY18 and an increase in NTA per share," it said. Net tangible assets per share dropped to 68 cents at balance date from $1.17 a year earlier.
Powerhouse was established to help commercialise research generated by universities in New Zealand and Australia. It has a portfolio of 23 companies ranging from early stage to mature businesses in clean-tech and engineering, medical and healthcare, agritech and environmental, and ICT.
The biggest shareholder in Powerhouse is Christchurch City Council-owned Canterbury Development Corp with 22.5 per cent.
