HS Optimus (SGX:504) expects a larger net loss for the half year ended Sept. 30, compared with the previous year, according to a Friday filing on the Singapore Exchange.

The company cited ongoing macroeconomic uncertainties and inflation as factors leading to reduced revenue.

Additionally, a decline in the US dollar against the Malaysian ringgit is projected to cause significant unrealized foreign exchange losses in the fiscal half year, reversing the gains from a year ago, the filing said.
