Henderson Land Development Co. said its net profit for the first half fell 62% from a year earlier despite higher revenue, as a substantial fair value loss on its investment properties dragged earnings.

The developer posted a net profit of 2.83 billion Hong Kong dollars (US$365.1 million) for the period.

Revenue rose 35% from a year earlier to HK$10.94 billion, thanks to an 83% surge in property sales, as the low-interest rate environment supported the real estate market.

Looking ahead, Henderson Land said it expects the operating environment to remain challenging amid the "lingering Covid-19 pandemic, strained Sino-U.S. relations and heightened geopolitical tensions."

The firm also expects potential further fair value losses on its investment properties, as the public health crisis pressures property prices.
