A2 Milk shares jumped 14.2 percent after the company said it expects annual operating profit margin will be stronger than previously communicated and in the range of 29-30 per cent.
The shares jumped to $14.62 from $12.80 when trading opened at 10am, still shy of its record at $18.04 at the end of July.
The alternative milk and infant formula company said it expected to see strong revenue growth, supported by its investment in China and the United States, in the current financial year.
"Overall, for FY20 we anticipate continued strong revenue growth across our key regions supported by brand and marketing investment in China and the US and the development of both capability and infrastructure to support in-market execution," chief executive Jayne Hrdlicka said in notes prepared for the annual meeting today.
She said the company's earnings before interest, tax, depreciation and amortisation margin percentage was now anticipated to be stronger than previously announced, and in the range of 29-30 per cent.
The margin would benefit from improved price yields and a reduction in the cost of goods sold.
Shares in a2 Milk are expected to rally when the market opens at 10 am, on the back of a2 Milk's better than expected margins, Matt Goodson, managing director of Salt Funds, said.
