UPDATED - Automation and robotics exporter Scott Technology enjoyed a multi-million dollar profit increase in the year to August, driven by strong growth across its divisions.

The company today reported profit before tax of $5.5m on operating revenues of $46.6m for the year ended 31 August 2010, compared to respective results of $400,000 and $31.3m in the 2009 year.

Mighty River Power, the final major power company to post its annual results, has made the best of extremely challenging hydro conditions in the year to 30 June 2010.

The company emphasised underlying earnings after tax of $139.6m and ebitdaf of $327.8m – both close to growth targets projected in May.

This compares to underlying earnings last year of $211.7m and epitdaf of $251m.

“Last year’s result really represented an alignment of all the stars for Mighty River Power,” chairwoman Joan Withers told media during a briefing this morning.

The year to 30 June 2010 was a year of two halves for state-owned coal miner Solid Energy.

A net profit after tax of $67.8m represents a major turnaround on a $6.5m loss at the half year – but is 39% down on last year’s full year result of $110.8m.

Solid Energy chairman John Palmer attributed the reduced full year profit to weak international demand and prices and prolonged industrial action.

Revenue is down 29.6% on last year to $690m, with almost two thirds achieved in the second half of the year. No announcement on full year dividend has been made.

New Zealand Oil and Gas (NZOG) will pay a dividend for the third consecutive year – despite a net loss after tax of $3.3m in the year to 30 June 2010.

Last year, the company reported an after tax profit of $53.2m, largely driven by the ongoing success of the Tui area oil fields, in which NZOG holds a 12.5% stake.

This year’s results reflect a predicted decline in yield from Tui and a significant increase in exploration expenditure.

Total operating revenue this year sits at $99.4m, down 28% on last year.

Sky City Entertainment Group has achieved the double-digit growth it was aiming for with a record full-year net profit of $141.7 million.

The result, for the year to June 30, is up $26.4 million, or almost 30% on the same time last year.

During the year, the casino, hotel and restaurant operator earned revenue of $837.9m – down 1% on the same time last year.

A one-off, deferred tax liability of $39.7 million was incurred from changes to the way buildings are depreciated, announced in the May budget.

Adjusting for this amount, net profit was $102 million.

Despite a record result, Solid Energy is blaming plummeting international coal prices and demand in the second half of the year for an annual profit below half of what it forecast.

But the company’s hedging policy also resulted in a foreign exchange loss of $102 million and as market volatility continued, Solid Energy made impairment and onerous contract adjustments that reduced net profit before tax by $26.7 million.

The $111 million record-profit was up from $34 million in 2008 and its base revenue almost doubled to $980 million, from $552 million in 2008.
