Date of events: 2017/12/14

To which item it meets: paragraph 49

Statement:

1. Date of occurrence of the event: 2017/12/14

2. Company name: Advanced Semiconductor Engineering, Inc.

3. Relationship to the Company (please enter ”head office” or ”subsidiaries”): head office

4. Reciprocal shareholding ratios: N/A

5. Cause of occurrence: ASE and SPIL signed a Supplemental Agreement to Joint Share Exchange Agreement to amend and extend the Long Stop Date of Joint Share Exchange.

6. Countermeasures: N/A

7. Any other matters that need to be specified: Advanced Semiconductor Engineering, Inc. (TWSE Code: 2311, NYSE Code: ASX) (”ASE”) and Siliconware Precision Industries Co., Ltd. (”SPIL”)(Taiwan Stock Exchange: 2325, NASDAQ: SPIL) have entered into a Joint Share Exchange Agreement (the “Joint Share Exchange Agreement”) on June 30, 2016, whereby ASE will file an application to establish ASE Industrial Holding Co., Ltd. (“HoldCo”) by means of a statutory share exchange, and HoldCo will acquire all issued and outstanding shares of both ASE and SPIL. Upon the closing of the share exchange, ASE and SPIL will be delisted from the Taiwan Stock Exchange and become wholly-owned subsidiaries of HoldCo concurrently (the “Joint Share Exchange”). Since ASE and SPIL only received the conditional approval on the Joint Share Exchange from the Anti-Monopoly Bureau under the Ministry of Commerce of the People’s Republic of China (”MOFCOM”) on November 24, 2017, to accommodate the time required for closing, ASE and SPIL have signed a supplemental agreement (“Supplemental Agreement”) to Joint Share Exchange Agreement extend the last day of the Joint Share Exchange from December 31, 2017 to October 31, 2018. The Supplemental Agreement will be effective upon the approval by ASE’s and SPIL’s respective board of directors.

ASE and SPIL will continue with the establishment of HoldCo. It is expected that an extraordinary general meeting will be convened in February 2018 and the establishment of HoldCo will be completed by the end of April 2018. This timeline, however, is subject to the review progress of the competent authorities.
