HTC sells its own smartphones and also makes handsets for a number of leading US companies, including Google's Nexus One.
The company has recently unveiled a new series of smartphones as it faces intense competition from Apple and South Korea's Samsung and seen its third quarter profit tumble 79.1 percent year-on-year.
