In 2014, the company raised $17m selling shares at $1.10 apiece and existing investors sold a further $5m into the offer, however, the stock has been punished as a slowing Australian economy and late product launches weighed on Serko's revenue.
Serko raised $8.1m from institutional and existing investors at 84 cents apiece in late 2015 to help fund a marketing push and product launch, having previously signalled it didn't plan to go back to the market after its June 2014 initial public offering.
In March it said its existing Callaghan Innovation Grant has been extended for a further 2 years, to June 30, 2019 - with an additional value of $2m. The new funding is an extension to a previous $4.2m Callaghan Innovation Research and Development Growth Grant. The additional funding is being used to fuel development of its predictive technology, it said.
The stock last traded up 7 per cent at $0.80 and is up 8.2 per cent over the past year.
