The group helps its customers to streamline retail offerings to passengers.
In July, Datalex announced plans for the potential equity fundraising, which was expected to take place in early autumn.
The capital raise was completed at a premium to the current share price following support from shareholders, the company confirmed in a statement today.
Funds raised will be used to repay the entire debt owed to Tireragh, a company controlled by billionaire Dermot Desmond.
Datalex secured a loan facility of €5m last year from Tireragh.
This brings its total loan facility to €15m with a repayment date set for the end of this year, according to annual results published earlier this year.
Around €13m has been drawn down so far.
The equity fundraising was supported by Mr Desmond, who owns just over 40pc of the stock market-listed software firm. Mr Desmond had told the group that he would procure support for the planned fundraising.
Datalex added earlier this year that the planned fundraising could also provide sufficient working capital for investment in the group’s product roadmap and activation projects, while it also continues to compete for new revenue opportunities.
“The funds will be used to strengthen the Company’s balance sheet, enabling us to complete the repayment of the outstanding Tieragh loan facility and transition to a more sustainable capital structure for the group,” Datalex chief executive Jonathan Rockett said.
“This marks the beginning of a new chapter for Datalex; a chapter which will provide the company with greater scope to implement is growth strategy, generate new revenue opportunities, accelerate investment in our product roadmap and continue with activation projects and opening the door for exciting partnerships,” he added.
Datalex reported a loss after tax of $6.1m (€5.5m) in the first half of 2024, a slight improvement from the same time last year.
The group also reported an Ebitda (earnings before interest, taxes, depreciation, and amortisation) loss of $2m (€1.8m).
This was a 37pc improvement from the first half of 2023, with Datalex attributing this to gross profit growth and positive foreign exchange gains.
The company recorded total revenue of $13.2m (€11.8m) in the first half of the year, up 3pc compared to the same period in 2023.
Platform revenue increased 14pc to $7.3m following product activations with new customers.
