Earlier today, Acer posted its earnings report from Q1 of 2011. The company saw after-tax earnings per share hit an eight year low of NT$0.45 as PC shipments declined. Acer accrued NT$1.93 billion in operating net income, which was down nearly 56% quarter-over-quarter. The company does expect its operating profit margin to remain flat year-over-year, but industry analysts are forecasting a 1% to 2% decline.
