However the results are likely to be better three months from now as nine in 10 of the dealerships have reopened.
In China, where Aston Martin restarted sales in June, retail sales are up 11% – an “encouraging” sign, bosses said on Wednesday.
Shares rose by around 8%.
It has been a turbulent six months for Aston Martin, which was forced to raise £688 million from a consortium of shareholders led by new chairman Lawrence Stroll.
He said: “Obviously, it has been a challenging period with our dealers and factories closed due to Covid-19, in addition to aligning our sales with inventory with the associated impact on financial performance as we reposition for future success.
“However, I have been most impressed that through this most challenging of times we have been able to reduce our dealers’ sports car inventory by 869 units.”
Meanwhile, the business said that an accounting method error in the US had forced it to recalculate some of its figures from last year.
It meant a reduction of £15.3 million in earnings before interest and tax in 2019.
