Independent research house Morningstar has come out in favour of the upcoming Meridian Energy float, saying it is likely to appeal to long-term investors seeking yield.
But Morningstar said the company, which accounts for 30 per cent of New Zealand's electricity output, would be susceptible to political change and the weather.
Independent valuations from Morningstar ($1.75), Wellington-based investment bank Woodward Partners ($1.81) and TDB Advisory ($1.70) were all at the top end of the Government's final price range of $1.50 to $1.80.
Brokers First NZ Capital, which is also not involved in the partial privatisation process, was more conservative. Applying Contact Energy and Mighty River multiples would indicate a fully paid trading range for Meridian shares of between $1.43 and $1.60, with a $1.51 midpoint, First NZ said.
All four valuation reports published to date pointed to the risks associated with the Labour/Greens' plan to take control of the electricity market, but ascribed less risk to the possibility of Meridian's biggest customer, the Tiwai Point aluminium smelter, pulling out.
