TAIPEI, Taiwan, Aug. 21, 2015 -- Advanced Semiconductor Engineering, Inc. (TAIEX: 2311, NYSE: ASX) ("ASE") announced today that it plans to commence on August 24, 2015, tender offers in the Republic of China and the United States for common shares and American Depositary Shares ("ADSs") of Siliconware Precision Industries Co., Ltd. ("SPIL") at a price of NT$45 per common share and NT$225 per ADS payable in the equlvant amount of U.S. dollars, respectively. The Taiwan offer is being made to all holders of common shares and the U.S. offer is being made to all holders of ADSs.

The Taiwan offer will commence at 9:00 a.m., Taiwan time, on August 24, 2015 and expire at 3:30 p.m., Taiwan time, on September 22, 2015.  The U.S. offer will commence at 12:01 a.m., New York City time, on August 24, 2015 and expire at 12:00 p.m. noon, New York City time, on September 22, 2015.  ASE plans to acquire an estimated maximum number of 779,000,000 common shares of SPIL (including common shares represented by ADSs), equivalent to approximately 25% of the common shares issued by SPIL.

In the face of intensifying global competition and rising of new contenders, the drive for consolidation of the semiconductor industry is becoming increasingly apparent.  ASE believes that industry peers in Taiwan should actively search for opportunities to cooperate and integrate resources, in order to protect and further improve the competitive advantage of the Taiwanese packaging and testing industry.  The purpose of ASE acquiring an equity interest in SPIL through the tender offer is to establish the basis and opportunity for exploration of possible avenues of cooperation between ASE and SPIL; within the legally permitted scope and taking into full consideration the mutual interests of both parties' employees and shareholders, ASE is willing to discuss specific details of such avenues of cooperation with SPIL's operations team.  Until such time, the acquisition of equity interest in SPIL by ASE through this tender offer is purely a financial investment, and ASE will not intervene in SPIL's operations.  As SPIL reported strong operating performance in the past, ASE believes that its financial investment should yield excellent return.

During the tender offer period, if the number of common shares tendered in Taiwan reaches the minimum number of 155,818,056 shares (equivalent to 5% of common shares issued by SPIL), ASE shall lawfully acquire common shares and ADSs of SPIL tendered in the Taiwan and U.S. offers up to the limits expressed in the second paragraph, and subject to proration, as described in the the Taiwan and U.S. offers, and subject to the terms and conditions of the Taiwan and U.S. offers.
