Acer on Friday drastically lowered its 2011 shipment forecast for tablet PCs, Taiwan Economic News reported. The company now anticipates shipping approximately 2.5 million consumer tablets in 2011, down 50% or more from earlier projections of between 5 and 7 million units. Acer chairman J. T. Wang said at a shareholder meeting that Acer would likely meet its second-quarter shipment goals, which are down 10% sequentially, and that third-quarter shipments could be marginally better. Wang said performance will likely not improve until the company’s planned restructuring is completed in the fourth quarter, however. Company president Jim Wong said the company lowered its tablet shipment forecast due mainly to excessive inventory that has built up at distributor locations. Wong believes end user sales have been lower than expected because of strong competition from competing tablet models.
