Rights Offering for Common Shares

Advanced Semiconductor Engineering, Inc.
(Incorporated as a company limited by shares in the Republic of China)

_______________

We distributed to holders of our existing common shares rights to subscribe for an aggregate of 240,000,000 of our common shares, par value 10 NT dollars per share (the “New Shares”). Each common share held of record as of 5:00 p.m. (the close of trading on the Taiwan Stock Exchange) on February 15, 2017 (Taiwan time) entitled its holder to one right to subscribe for 31.23335914 New Shares at the subscription price of NT$34.30 per New Share (the “Subscription Price”). A holder of rights that exercised all of its rights was also able to apply during the Preemptive Subscription Period (as defined below) to subscribe at the Subscription Price for additional New Shares that were not subscribed for pursuant to the exercise of rights (the “Additional Shares”). We accepted subscription for whole common shares only. The subscription period for the rights commenced on February 21, 2017 and expired at the close of business in Taiwan on March 21, 2017 (the “Preemptive Subscription Period”) and after the Preemptive Subscription Period, New Shares, including fractional New Shares, that were not subscribed for were offered at the Subscription Price to Chairman of ASE’s Board of Directors and his designated persons (the “Designated Persons”) during a period starting on March 23, 2017 (Taiwan time) following the expiration of the Preemptive Subscription Period (as defined below) and ending at the close of business in Taiwan on March 27, 2017 (the “Additional Shares Allocation Period”).

Holders of American Depositary Shares, or ADSs, each representing five common shares, did not receive rights to subscribe for new ADSs. The rights with respect to ordinary shares represented by ADSs were issued to Citibank, N.A., as depositary (the “Depositary”). At the instruction of holders, a total of 15,321,903 ADSs were cancelled during the period from February 16, 2017 until March 7, 2017, and the shares and the rights underlying such ADSs were delivered upon the instruction of the cancelling holders. The Depositary determined, in consultation with us, that it was not reasonably practicable to sell the rights it receives with respect to the common shares represented by ADSs (as the rights are not listed or eligible to trade on any securities exchange), and therefore such rights were not sold by the Depositary and the holders of ADSs will not receive any cash proceeds from the sale of rights.

We made this offering directly to shareholders without the use of any underwriters, agents or dealers.

The results of the offering are set forth below:

194,863,030 New Shares were subscribed for by the holders of rights during the Preemptive Subscription Period; and

45,136,970 Additional Shares were subscribed for by the Designated Persons during the Additional Shares Allocation Period.
