Aston forecast sales of 6,300-6,500 cars to dealers this year, down from earlier prediction of 7,100 to 7,300.
A "challenging external environment" had worsened, it said, as had "macro-economic uncertainties".
"We anticipate that this softness will continue for the remainder of the year and are planning prudently for 2020," it said.
The BBC noted Aston was the latest car company to take a hit to its business from a slowdown in consumer confidence in Europe.
