Acer and Pegatron both declined to comment on the news.
Acer's existing ultrabook models are outsourced to Wistron with the devices' global sales expected to reach 250,000-300,000 units by the end of 2011.
For 2012, Digitimes Research expects Pegatron's total notebook shipments to reach 18.99 million units, up 22% on year, and the maker will stay firmly as the fourth largest notebook ODM worldwide.
