The SENS statement said much the decline in revenue for its South African industrial services and support services businesses was due to poor macroeconomic conditions.
"As the market leader in the South African staffing industry, it goes without saying that we are directly impacted by South Africa's economic and employment woes.
"In the first half of this year, unemployment increased to 29%, business confidence fell to the lowest level in over two decades and the post-election economic relief, which many of our corporate clients were holding out for, has not materialised," the statement said.
The statement added that in South Africa, Adcorp remained a stable business and that its focus over the short term would be the implementation of "tactical interventions to claw back on the losses" incurred in the first half of 2019.
On Wednesday afternoon, Adcorp shares were changing hands at R14.00, compared to R23.57 per share in mid-July.
