According to Digitimes, each shipped about eight million own-brand motherboards globally during the first half of 2015 and are only expected to deliver 18 million units each in the whole year.
This is down from an original forecast of 20 million units each. Gigabyte is coming off the worse because of weakening motherboard shipment performance and the fact that its other product lines only performed mildly.
Asustek and Gigabyte are flat out competing aggressively over pricing and smaller companies such as MSI, ASRock, Elitegroup Computer Systems and Biostar have all seen serious impacts on their profitability.
ASRock and MSI both shipped around two million motherboards in the first half and may ship less than six million units in 2015.
MSI was able to claw back a lot thanks to its successful gaming notebook line so is not in such a dire predicament.
ASRock is pushing into the server and industrial PC industries, but is losing seeing profit fall as the two businesses so far still have not yet had any major contribution to its bottom line.
ECS already stepped out of the brand motherboard business and Biostar is expected to ship 2.5-3 million motherboards in 2015.
