Gianpiero Morbello, Acer's UK managing director, said: "We decided not to renew the contract when it expired. Northamber did not shift as much stock as we needed them to last year. Their results were poor."
A representative from Northamber told CRN: "We weren't really handling that much Acer stock anyway."
The removal of Northamber leaves Computer 2000, Enta, ETC, Ingram, Lynx, Micro-Peripherals, VIP Computers, and Westcoast as Acer's distributors.
Gianpiero said the vendor would not be replacing Northamber.
The move follows the termination of Acer's contract with distributor Midwich last year.
