Amkor announced pricing for a secondary offering of 10 million shares at $48.75. The shares are being sold by 915 Investments, which is an investment vehicle for the Kim family and the company's Chairman. The company won't receive any proceeds from the sale since it's entirely from existing shareholders. Following the sale, the Kim family will still own over 49% of the stock. They have a 180-day lock-up period for their remaining shares.
