Open Country has yet to pay a dividend, eschewing payouts in favour of investment for future growth. Margrain said it was looking to invest in more plant in the Waikato but that wasn't on the cards for this financial year.
"You could expect to see measured investment forward in the future," he said.
The company paid $507.9m for milk in the latest financial year, up from $480.2m a year earlier. Receipts from customers rose to $811.2m from $707.4m.
Founded in 2001 as a rival to dairy giant Fonterra Cooperative Group, Open Country's first Waharoa cheese factory started production in 2004 and the company has since expanded throughout the country, building factories in Southland and Wanganui to enable it to source milk from the country's largest dairying regions. In its early stages, the company's focus was on producing commodity products such as whole milk powder, however in recent times it has ramped up production of higher value products.
"We continued our push into higher value food ingredients," Margrain said. "We make considerably less baseline whole milk powders than we used to, we are now more about supplying our major customers around the world with high quality higher value food ingredients, not branded products per se but food ingredients. That's been an aspiration of ours for some years, we continue to fulfill it and we will keep doing it."
He declined to detail the percentage of milk powder the company now produced, compared with past years.
Open Country expects to pay its farmer suppliers around $6 per kilogram of milk solids for the current 2016/17 season. That's above the level most farmers require to produce a profit, following two years below breakeven level, and Margrain said the payout is also likely to be profitable for next year as global demand and supply come into balance. The company hasn't yet forecast a payout for next season.
"At the moment we think they are not too badly matched in terms of the growth in demand and the growth in supply, and so you would expect logically that there is a much higher degree of stability likely in the next 12 months than has been in the last two years," Margrain said. "Our view is that we are in a relatively stable market period at this point in time, and we see no logical reason why that should dramatically change."
Still, he said global competition is "very severe".
"It's hard work, it's a volatile industry, it's an industry in which you should operate conservative balance sheets and one should never ever be complacent."
