One quarter into the current financial year, Verbiest said the company was striving for a return to sustainable earnings growth.
In August, the company said it was targeting low, single-digit growth in operating earnings and a low, single-digit decline in total revenue.
"When we outlined our core strategy to investors in May 2013, we said that we realistically expected 2014 and 2015 to be years in which we stabilised the business and reduced costs, targeting revenue and margin growth and improvement in unit costs in 2016 and beyond," Verbiest said.
"If anything, we actually think we are slightly ahead of this plan, however, we know that the market is not standing still - competition remains intense, particularly in the mobile and broadband markets."
In its latest result for the June year, Spark reported its profit from ordinary activities came to $321 million, excluding discontinued operations, up 19.8 per cent on the previous year, he said.
