In 2016, the company made its first ebitda profit of $204,000, compared to an ebitda loss of $1.4m a year earlier.
The company prefers ebitda because it believes the measure avoids distortions. It's forecasting ebitda in 2018 of between $2m and $4m, and a net profit.
"We continue to be satisfied with our top line growth trend in Q3 but margin and profit performance was disappointing for the quarter," chief executive Greg Allen said.
"While we had expected to make a loss in Q3 due to seasonality of demand, it turned out worse than forecast. We do expect a stronger Q4, closer to revenue and margin levels seen earlier in the year, subject to the caveat that those later Q4 orders are reducing our normal revenue visibility.
"The company's provisional FY2018 growth and earnings outlook are underpinned by the expectation of adding further new customers, continuing growth in demand for our new products and lower supply chain costs," Allen said.
The shares last traded at 17 cents, up 4.9 per cent this year.
