"Stock levels are also well managed."
ShareClarity managing director Daniel Kieser said Hallenstein Glasson's forecast result was impressive.
"With inventory levels under control, it says their products are on trend and selling. It also suggests their new concept mega stores are continuing to gain traction," Kieser said.
Revenue growth in the second-half was down 13 per cent, from 19 per cent in the first half.
"Still a great result, but I wouldn't be surprised if some investors had priced in a higher second-half growth," he said.
The retailer sold Storm to the sub-brand's management for an undisclosed sum that wasn't material to earnings, saying the unit wasn't a core business.
Instead, Hallenstein Glasson planned to focus its efforts on expanding its two major brands.
Storm chief executive Deborah Caldwell, who owns the brand through her newly-established company Blackstar Holdings, said the group's results had nothing to do with the sale of Storm.
"We had no asset value to them," Caldwell said.
"We congratulate the group on their trading results, and we continue to have a strong and supportive relationship."
Hallenstein Glasson will make a full earnings statement on September 28.
Its shares last traded at $5.53 and have gained 40 per cent so far this year.
