"The results follow an intensive year of strategic acquisitions and business integration effort that will enable us to build on the continuous growth since the IPO, and to deliver an increased performance rate across the global utilities and airports businesses," chief executive Ian Black said.
"Both businesses experienced 40 percent plus revenue growth over prior year and recurring revenues from annual fees and support services were up 43 percent."
In 2017, Gentrack added 12 new utility and nine new airport customers, launched its first South East Asian utilities office in Singapore, and entered new airport markets in Greenland, Abu Dhabi, Jersey, and Kenya.
Utilities is its biggest business, delivering $63.5m in revenue and $20.7m in ebitda in the latest year, while its airports revenue was $11.7m and ebitda was $3.2m. One-third of the company's revenue came from Australia, where energy regulatory reform is driving growth, 23 per cent from the UK and Europe, and 12 per cent from New Zealand.
The company lifted staff numbers 55 per cent in the latest year, to 429, with the bulk of those new hires in Europe. It says its expansion of offices in Melbourne and London will "support ongoing resource growth."
The shares last traded at $6.10, and have gained 75 per cent this year.
