Despite improved income streams leading to revenues jumping by 28.9pc to 4.29 billion Br, these gains did not translate into robust profit growth. Pre-tax earnings slid by 1.36pc to 714 million Br, while net profit inched ahead by just 2.1pc to 555 million Br. The borderline increase in net profit coincided with a slight dip in the net profit margin, which went to 12.94pc from 13.04pc a year earlier. Rising costs, particularly operating and personnel expenses, constrained the benefits of higher income.
