In an update, Rotala added that since April it had continued to align bus services with local requirements, reduce operating costs and conserve cash.
Cash flow, both at the underlying profit [EBITDA] level and net of all debt, interest and other payments, was quickly stabilised and remains positive, it said.
Rotala also negotiated an increase in its overdraft facility to £6.6mln in April and said it had operated well within that facility in the intervening period.
Interim results for the period to May 31, 2020, are scheduled to be released by mid-September and by no later than the end of the month, it added.
