Profit is expected to rise by at least 50% from the previous year, despite this year’s fairly ambitious target of VND700 billion in after-tax profit. Chairman Bolat emphasized that Coteccons continues to maintain positive cash flow, a clear testament to the company’s solid financial foundation. He noted that the figures shared today are not yet final results, but representing data Coteccons is confident enough to share with shareholders at this point.
