Quixant has lifted its H1 pretax profit to $4.4m, from $2.6m. Revenue was $41.3m, from $13.6m.
"Quixant's business is in excellent shape. Within the Gaming division, we have several opportunities to win major business with the largest gaming machine manufacturers and we have continued to invest in the business for many years to ensure we maximise our chances of success," the company said in a statement.
"Our decision to aggressively market our gaming monitor line has also yielded success in addressing our customers' desire to have a smaller number of trusted suppliers for the components in their machine. Consequentially, the impact is an increased spend with Quixant.
"The Densitron division has also demonstrated growth. We believe that the benefit of the enhancements will lead to improvements in profitability and growth over time in the division.
"Following a strong first half, we enter the second half of the year with confidence in achieving market expectations for the full year. Our positioning in several major opportunities also gives us strong confidence for continued growth in 2017 and beyond."
