Shareholders of Siliconware Precision Industries Co., Ltd.

Re: Notice of Extraordinary General Meeting of Shareholders

Dear Shareholder:

You are cordially invited to attend an extraordinary general meeting of shareholders of Siliconware Precision Industries Co., Ltd. (the “Company”) to be held on , 2017 at a.m. (Taipei time). The meeting will be held at Taichung Industrial Park Service Center Administrative Building, Floor 1, Conference Room 101, No. 2, Gongyecyu 5th Road, Situn District, Taichung City, Taiwan. The accompanying notice of the extraordinary general meeting and proxy statement provide information regarding the matters to be acted on at the extraordinary general meeting, including at any adjournment or postponement thereof.

At the extraordinary general meeting, you will be asked to consider and vote upon a proposal to approve the Joint Share Exchange Agreement dated June 30, 2016 (the “Joint Share Exchange Agreement”), between the Company and Advanced Semiconductor Engineering, Inc. (“ASE”) and to approve the transactions contemplated by the Joint Share Exchange Agreement. A copy of the English translation of the Joint Share Exchange Agreement is attached as Annex A to the accompanying proxy statement. Under the terms of the Joint Share Exchange Agreement, it is expected that ASE will incorporate ASE Industrial Holding Co., Ltd. (“HoldCo”), a holding company, which will (i) purchase the Company’s issued ordinary shares (the “Shares”) in cash and (ii) issue new shares to the shareholders of ASE (the “ASE Shareholders”) in exchange for the common shares of ASE (collectively, the “Share Purchase”). HoldCo will be a company incorporated in Taiwan, Republic of China (“Taiwan” or the “ROC”) which, upon the completion of the Share Purchase (the “Effective Time”), will be beneficially owned by the ASE Shareholders. If the Share Purchase is completed, the Company will continue its operations as a privately held company and will be beneficially owned by HoldCo. As the result of the Share Purchase, the Company’s American depositary shares (“ADSs”), each representing five Shares, will no longer be listed on the Nasdaq Global Market (“NASDAQ”) and the American depositary shares program for the ADSs will terminate.

If the Joint Share Exchange Agreement is approved by the requisite vote of the Company’s shareholders and the Share Purchase is completed:

| • |  | each Share issued immediately prior to the Effective Time, including the treasury shares of the Company and the Shares beneficially owned by ASE, will be transferred to HoldCo in exchange for the right to receive New Taiwan dollars (“NT Dollars” or “NT$”) 51.2 (the “Final Per Share Consideration”), which represents NT$55.0, the original per Share consideration under the Joint Share Exchange Agreement, minus a cash dividend and a return of capital reserve of NT$3.8 per Share distributed by the Company on July 1, 2016. The Final Per Share Consideration will be paid to the holders of the Shares in NT dollars in cash, without interest and net of any applicable withholding taxes; and

| • |  | each ADS, representing five Shares, including the ADSs beneficially owned by ASE, will be cancelled in exchange for the right to receive, through the ADS Depositary (as defined below), the U.S. dollar equivalent of NT$256 (representing five times the Final Per Share Consideration) minus the total of (A) all processing fees and expenses per ADS in relation to the conversion from NT dollars into U.S. dollars and (B) US$0.05 per ADS cancellation fees pursuant to the terms of the deposit agreement dated January 6, 2015 by and among the Company, JPMorgan Chase Bank, N.A. (the “ADS Depositary”) and the holders and beneficial owners from time to time of ADSs issued thereunder (the “Final Per ADS Consideration”). The Final Per ADS Consideration will be paid to the holders of ADSs in U.S. dollars in cash, without interest and net of any applicable withholding taxes.

The Shares owned by shareholders who have validly exercised and have not effectively withdrawn or lost their appraisal rights (the “Dissenting Shares”) under the ROC Business Mergers and Acquisitions Act (the “ROC M&A Act”) will be purchased by the Company for their appraised value or other agreed value in accordance with Article 12 of the ROC M&A Act, without interest and net of any applicable withholding taxes, as described in more detail below.

An audit committee of the board of directors of the Company (the “Board”), acting as the special committee of the Company pursuant to the ROC M&A Act and composed solely of independent directors (the “Special Committee”), has reviewed and considered the terms and conditions of the Joint Share Exchange Agreement and the transactions contemplated by the Joint Share Exchange Agreement, including the Share Purchase. The Special Committee unanimously determined that the terms and conditions of the Joint Share Exchange Agreement are reasonable and fair to the Company and submitted its review minutes and conclusions to the Board for consideration. Having carefully considered all relevant factors, including the unanimous determination of the Special Committee, the Board (a) determined that it is fair to and in the best interests of the Company, and declared it advisable, that the Company should approve and, as the case may be, enter into the Joint Share Exchange Agreement and the Share Purchase, (b) approved the execution, delivery and performance by the Company of the Joint Share Exchange Agreement and the completion of the transactions contemplated thereby, including the Share Purchase, and (c) directed that the authorization and approval of the Joint Share Exchange Agreement be submitted to a vote at an extraordinary general meeting of the shareholders of the Company and recommended that the shareholders of the Company authorize and approve by way of a special resolution the Joint Share Exchange Agreement and the Share Purchase.

The Board recommends that you vote FOR the proposal to approve the Joint Share Exchange Agreement and the transactions contemplated by the Joint Share Exchange Agreement, including the Share Purchase and FOR the proposal to authorize the persons designated by the Board (including the chairman of the Board, the president of the Company and/or the persons designated by them) to do all things necessary to give effect to the Joint Share Exchange Agreement.

The accompanying proxy statement provides detailed information about the Share Purchase and the extraordinary general meeting. We encourage you to read the entire document and all of the attachments and other documents referred to or incorporated by reference herein carefully. You may also obtain more information about the Company from documents the Company has filed with the Securities and Exchange Commission (“SEC”), which are available for free at the SEC’s website: www.sec.gov.

The Share Purchase cannot be completed unless the Joint Share Exchange Agreement and the transactions contemplated by the Joint Share Exchange Agreement, including the Share Purchase, are approved by an affirmative vote of shareholders representing (a) a simple majority of the voting power of the Shares present and voting in person or by proxy as a single class at the extraordinary general meeting at which shareholders representing two-thirds or more of the total number of the issued and outstanding Shares are present, or (b) two-thirds or more of the voting power of the Shares present and voting in person or by proxy as a single class at the extraordinary general meeting of the Company at which shareholders representing less than two-thirds but more than a simple majority of the total number of the issued and outstanding Shares are present. Each Share is entitled to one (1) vote on all matters subject to shareholders’ vote.

ii

Even if you plan to attend the extraordinary general meeting in person , we request that you either (i) complete the accompanying proxy card in accordance with the instructions provided on the proxy card, or (ii) vote electronically through a shareholder voting platform by accessing the following website: https://www.stockvote.com.tw/evote/login/shareholder.html, as promptly as possible. The deadline to lodge your proxy card is , 2017 at a.m. (Taipei time) (being no later than five (5) days before the date of the extraordinary general meeting). The deadline to exercise your electronic vote is , 2017 at a.m. (Taipei time) (being no later than two (2) days before the date of the extraordinary general meeting). Voting at the extraordinary general meeting will take place by poll voting as the chairman of the Board has undertaken to demand poll voting at such meeting. Each shareholder has one (1) vote for each Share held as of the close of business day in Taiwan on , 2017, the share record date (the “Share Record Date”).

The ADS Depositary, as the record holder of the Shares represented by ADSs, will NOT vote the Shares it holds on deposit at the extraordinary general meeting in accordance with the individual voting instructions it receives. Instead, the ADS Depositary will vote ALL the Shares it holds on deposit at the extraordinary general meeting as follows:

| • |  | if holders of at least 51% of the ADSs outstanding at 12:00 p.m. in New York City on , 2017 (the “ADS Record Date”), instruct the ADS Depositary to vote in the same manner regarding a resolution, the ADS Depositary will appoint Mr. Bough Lin, the chairman of the Board, or his designee (the “Voting Representative”), as the voting representative to vote ALL the Shares represented by the ADSs outstanding in the manner so instructed.

| • |  | if the ADS Depositary does not receive instructions from holders of at least 51% of the ADSs outstanding at the close of business in New York City on the ADS Record Date, to vote in the same manner regarding a resolution, the ADS Depositary itself will not provide any voting instruction and instead will appoint the Voting Representative to vote ALL the Shares represented by the ADSs outstanding as the Voting Representative deems appropriate, which may not be in your interest.

As a result, to the extent that you would like to ensure that the Shares underlying your ADSs are voted as you instructed, we urge you to consider whether you want to cancel your ADSs and become holders of Shares prior to the close of business in Taiwan on the Share Record Date, in accordance with the procedure described below.

As of the date hereof, the Company is not aware of any substantial opposition to any matter to be voted on at the extraordinary general meeting and does not believe that any such matter will have a material adverse impact on the rights of the Company’s shareholders. Holders of ADSs will not be able to attend the extraordinary general meeting unless they cancel their ADSs and become holders of Shares prior to the close of business in Taiwan on the Share Record Date. ADS holders who wish to cancel their ADSs need to make arrangements to deliver the ADSs to the ADS Depositary for cancellation before the close of business in New York City on , 2017 together with (a) delivery instructions for the corresponding Shares (name and address of the person who will be the registered holder of the Shares), and (b) payment of the ADS cancellation fees (US$0.05 per ADS to be cancelled) and any applicable taxes. If you hold your ADSs in a brokerage, bank or nominee account, please contact your broker, bank or nominee to find out what actions you need to take to instruct the broker, bank or nominee to cancel the ADSs on your behalf. Upon cancellation of the ADSs, the ADS Depositary will arrange for JPMorgan Chase Bank, N.A., Taipei Branch, the custodian holding the Shares, to transfer registration of the Shares to the former ADS holder (or a person designated by the former ADS holder). If after the registration of Shares in your name you wish to receive a certificate evidencing the Shares registered in your name, you will need to request the registrar of the Shares to issue and mail a certificate to your attention.

iii

Shareholders who elect to dissent from the Share Purchase will have the right to seek appraisal and payment of the fair value of their Shares if the Share Purchase is completed, but only if they deliver to the Company, before or during the extraordinary general meeting at which the vote is taken, a written objection or an oral objection that has been put into the record to the Share Purchase and subsequently comply with all procedures and requirements of Article 12 of the ROC M&A Act for the exercise of appraisal rights, the English translation of the relevant part of which is attached as Annex E to the accompanying proxy statement. The appraised value of your Shares as determined under that statute could be more than, the same as, or less than the Share Purchase consideration you would receive pursuant to the Joint Share Exchange Agreement if you do not exercise appraisal rights with respect to your Shares.

ADS HOLDERS WILL NOT HAVE THE RIGHT TO SEEK APPRAISAL AND PAYMENT OF THE FAIR VALUE OF THE SHARES UNDERLYING THEIR ADSs. THE ADS DEPOSITARY WILL NOT ATTEMPT TO PERFECT ANY DISSENTERS’ RIGHTS WITH RESPECT TO ANY OF THE SHARES THAT IT HOLDS, EVEN IF AN ADS HOLDER REQUESTS THE ADS DEPOSITARY TO DO SO. ADS HOLDERS WISHING TO EXERCISE APPRAISAL RIGHTS MUST SURRENDER THEIR ADSs TO THE ADS DEPOSITARY, PAY THE ADS DEPOSITARY’S FEES REQUIRED FOR THE CANCELLATION OF THE ADSs AND PROVIDE INSTRUCTIONS FOR THE REGISTRATION OF THE CORRESPONDING SHARES BEFORE THE CLOSE OF BUSINESS IN NEW YORK CITY ON , 2017, AND BECOME HOLDERS OF SHARES BY THE CLOSE OF BUSINESS IN TAIWAN ON THE SHARE RECORD DATE. THEREAFTER, SUCH FORMER ADS HOLDERS MUST COMPLY WITH THE PROCEDURES AND REQUIREMENTS FOR EXERCISING APPRAISAL RIGHTS WITH RESPECT TO THE SHARES UNDER ARTICLE 12 OF THE ROC M&A ACT.

Neither the SEC nor any state securities regulatory agency has approved or disapproved the Share Purchase, passed upon the merits or fairness of the Share Purchase or passed upon the adequacy or accuracy of the disclosure in this letter or in the accompanying notice of the extraordinary general meeting or proxy statement. Any representation to the contrary is a criminal offense.

It is expected that the common shares of HoldCo will be traded on the TWSE and the American depositary shares of HoldCo will be traded on the New York Stock Exchange. It is expected that HoldCo’s principal executive offices will be located at Room 1901, No. 333, Section 1 Keelung Rd. Taipei, Taiwan, Republic of China and its telephone number at the above address will be +886-2-6636-5678.

The Share Purchase

You are being asked to vote to approve the Share Purchase and the Joint Share Exchange Agreement, between the Company and ASE. Pursuant to the Joint Share Exchange Agreement, a holding company, HoldCo, will be formed at the Effective Time and the HoldCo will (i) acquire all Shares by paying the Share Purchase consideration in cash and (ii) issue new shares to the shareholders of ASE in exchange for the ASE Shares. Once the Joint Share Exchange Agreement is approved by the requisite vote of the shareholders of the Company and ASE and the other conditions to the completion of the transactions contemplated by the Joint Share Exchange Agreement are satisfied or waived in accordance with the terms of the Joint Share Exchange Agreement and upon the consummation of the Share Purchase, the Company will cease to be a publicly-traded company and will become a wholly-owned subsidiary of HoldCo. Following the completion of the Share Purchase, the Company will continue to do business under the name “Siliconware Precision Industries Co., Ltd.” A copy of the English translation of the Joint Share Exchange Agreement is attached as Annex A to this proxy statement. You should carefully read the Joint Share Exchange Agreement in its entirety because the Joint Share Exchange Agreement, not this proxy statement, is the legal document that governs the Share Purchase.

Share Purchase Consideration (Page 80)

Under the terms of the Joint Share Exchange Agreement, at the completion of the Share Purchase (the “Effective Time”):

| • |  | each Share issued immediately prior to the Effective Time (including the Company’s treasury shares and the Shares beneficially owned by ASE) will be transferred to HoldCo in exchange for the right to receive NT$51.2 (the “Final Per Share Consideration”), which represents NT$55.0, the original per Share consideration under the Joint Share Exchange Agreement (the “Original Per Share Consideration”), minus a cash dividend and a return of capital reserve of NT$3.8 per Share distributed by the Company on July 1, 2016. The Final Per Share Consideration will be paid to the holders of the Shares in NT dollars in cash, without interest and net of any applicable withholding taxes; and

| • |  | each ADS, representing five Shares, including the ADSs beneficially owned by ASE, will be cancelled in exchange for the right to receive, through the ADS Depositary, the US dollar equivalent of NT$256 (representing five times the Final Per Share Consideration) minus the total of (A) all processing fees and expenses per ADS in relation to the conversion from NT dollars into U.S. dollars and (B) US$0.05 per ADS cancellation fees pursuant to the terms of the Deposit Agreement (the “Final Per ADS Consideration”). The Final Per ADS Consideration will be paid to the holders of ADSs in U.S. dollars in cash, without interest and net of any applicable withholding taxes.

Please see “Dividend Policy” beginning on page 72 for additional information in respect of the cash distribution made by the Company on July 1, 2016. Each outstanding Dissenting Share will be purchased by the Company for its appraised value or other agreed value in accordance with the ROC M&A Act, without interest and net of any applicable withholding taxes.

The Company’s Zero Coupon Convertible Bonds due 2019

As of [ ] 2017, the Company had outstanding zero coupon convertible bonds due 2019 (the “Bonds”) in the aggregate principal amount of US$[ ] million. According to the terms and conditions included in the indenture related to the Bonds (the “Indenture”), bondholders may take the following actions in respect of the Share Purchase:

Conversion

Under the terms and conditions of the Bonds, holders of the Bonds can elect to convert their outstanding Bonds into Shares by , 2017, being the last business day before the 30-day period prior to the extraordinary general meeting. Holders of the Bonds will be permitted to convert each outstanding Bond (with a US$1,000,000 principal amount) at a conversion price of NT$[45.7579] per Share or [7.528] per ADS.

Under the terms and conditions of the Bonds, on the day that a holder of the Bonds properly deposits a conversion notice, the holder of such Bond will be deemed to be a holder of Shares he or she is entitled to receive upon conversion. Accordingly, a holder of Bonds who properly deposits a conversion notice prior to the Effective Time will be permitted, like all other shareholders of the Company, to receive the Share Purchase consideration.

Change of Control Repurchase

Under the terms and conditions of the Bonds, the completion of the Share Purchase is considered a “change of control” event, and the holders of the Bonds shall have the right to require the Company to repurchase, in whole or in part (being $250,000 in principal amount or an integral multiple thereof), such holder’s Bonds on the date set by the Company for such repurchase, which shall be less than 30 days but no more than 60 days following the date on which the Company notifies the trustee for the Bonds of the change of control event. The repurchase price for each Bond with a principal amount of US$1,000,000 is expected to be US$[1,020,150.52], US$[1,025,251.24] and US$[1,030,377.52] if the notice is given in the period of October 31, 2016, April 30, 2017 and October 31, 2017, respectively.

3

Delisting Repurchase

Under the terms and conditions of the Bonds, the completion of the Share Purchase is considered a “delisting” event, and the holders of the Bonds shall have the right to require the Company to repurchase, in whole or in part (being $250,000 in principal amount or an integral multiple thereof), such holder’s Bonds on the date set by the Company for such repurchase, which shall be less than 30 days but no more than 60 days following the date on which the holders of the Bonds are notified of the delisting event pursuant to the notice procedures set forth in the Indenture. The repurchase price for each Bond with a principal amount of US$1,000,000 is expected to be US$[1,025,251.24] and US$[1,030,377.52] if the notice is given in the six-month period ending April 30, 2017 and October 31, 2017, respectively.

Treatment of the Bonds under the Joint Share Exchange Agreement

If any of the Bonds have not been redeemed or repurchased by the Company and cancelled or converted by holders of the Bonds prior to the Effective Time, HoldCo, as co-obligors with the Company pursuant to a supplemental indenture to be entered into among HoldCo, the Company and the trustee of the Bonds, will pay the Final Per Share Consideration (subject to additional adjustments according to the terms of the Joint Share Exchange Agreement and applicable laws) to such holders of the Bonds for each Share they are entitled to receive if they exercise their conversion rights after the Effective Time.

Record Date and Voting Information (Page 74)

Before voting your Shares, we encourage you to read this proxy statement in its entirety, including all of the annexes, attachments, exhibits and materials incorporated by reference, and carefully consider how the Share Purchase will affect you. You are entitled to vote at the extraordinary general meeting if you have Shares registered in your name at the close of business in Taiwan on the Share Record Date. To ensure that your Shares can be voted at the extraordinary general meeting, please either submit your proxy in accordance with the instructions set forth on the proxy card or vote electronically through a shareholder voting platform by accessing the following website: https://www.stockvote.com.tw/evote/login/shareholder.html, as promptly as possible. The deadline to lodge your proxy card is , 2017 at a.m. (Taipei time) (being no later than five (5) days before the date of the extraordinary general meeting) and the deadline to exercise your electronic vote is , 2017 at a.m. (Taipei time) (being no later than two (2) days before the date of the extraordinary general meeting). Voting at the extraordinary general meeting will take place by poll voting as the chairman of the Board has undertaken to demand poll voting at such meeting. Each shareholder has one vote for each Share held as of the close of business on the Share Record Date.

If you own ADSs as of the close of business in New York City on , 2017, you cannot vote at the extraordinary general meeting directly, but you may instruct the ADS Depositary (as the holder of the Shares underlying the ADSs) how to vote the Shares underlying your ADSs. The ADS Depositary must receive such instructions no later than 12:00 p.m. (New York City time) on , 2017 in order to ensure that the Shares underlying your ADSs are properly voted at the extraordinary general meeting. If you hold ADSs, please complete, sign, date and return the ADS voting instructions card to the ADS Depositary. If a broker holds your Shares or ADSs in “street name,” your broker should provide you with instructions on how to vote your Shares or ADSs.

4

However, please be aware that the ADS Depositary, as the record holder of the Shares represented by ADSs, will NOT vote the Shares it holds on deposit at the extraordinary general meeting in accordance with the individual voting instructions it receives. Instead, the ADS Depositary will vote ALL the Shares it holds on deposit at the extraordinary general meeting as follows:

| • |  | if holders of at least 51% of the ADSs outstanding at the close of business in New York City on the ADS Record Date, instruct the ADS Depositary to vote in the same manner regarding a resolution, the ADS Depositary will appoint the Voting Representative to vote ALL the Shares represented by the ADSs outstanding in the manner so instructed.

| • |  | if the ADS Depositary does not receive instructions from holders of at least 51% of the ADSs outstanding at the close of business in New York City on the ADS Record Date, to vote in the same manner regarding a resolution, the ADS Depositary itself will not provide any voting instruction and instead will appoint the Voting Representative to vote ALL the Shares represented by the ADSs outstanding as the Voting Representative deems appropriate, which may not be in your best interest.

As a result, to the extent that you would like to ensure that your Shares are voted as you instructed, we urge you to consider whether you want to cancel your ADSs and become holders of Shares prior to the close of business in Taiwan on the Share Record Date in accordance with the procedure described below.

Holders of ADSs will not be able to attend the extraordinary general meeting unless they cancel their ADSs and become holders of Shares prior to the close of business in Taiwan on the Share Record Date. ADS holders who wish to cancel their ADSs need to make arrangements to deliver the ADSs to the ADS Depositary for cancellation before the close of business in New York City on , 2017 together with (a) delivery instructions for the corresponding Shares (name and address of the person who will be the registered holder of the Shares), and (b) payment of the ADS cancellation fees (US$0.05 per ADS to be cancelled) and any applicable taxes. If you hold your ADSs in a brokerage, bank or nominee account, please contact your broker, bank or nominee to find out what actions you need to take to instruct the broker, bank or nominee to cancel the ADSs on your behalf. Upon cancellation of the ADSs, the ADS Depositary will arrange for JPMorgan Chase Bank, N.A., Taipei Branch, the custodian holding the Shares, to transfer registration of the Shares to the former ADS holder (or a person designated by the former ADS holder). If after the registration of Shares in your name you wish to receive a certificate evidencing the Shares registered in your name, you will need to request the registrar of the Shares to issue and mail a certificate to your attention.

Each outstanding Share on the Share Record Date entitles the holder to one vote on each matter submitted to the shareholders for approval at the extraordinary general meeting and any adjournment thereof. We expect that, as of the Share Record Date, there would be [265,676,800] Shares entitled to be voted at the extraordinary general meeting. .

Shareholder Vote Required to Approve the Joint Share Exchange Agreement (Page 75)

Approval of the Joint Share Exchange Agreement requires the approval by an affirmative vote of shareholders representing (a) a simple majority of the voting power of the Shares present and voting in person or by proxy as a single class at the extraordinary general meeting at which shareholders representing two-thirds or more of the total number of the issued and outstanding Shares are present, or (b) two-thirds or more of the voting power of the Shares present and voting in person or by proxy as a single class at the extraordinary general meeting of the Company at which shareholders representing less than two-thirds but more than a simple majority of the total number of the issued and outstanding Shares are present. Each Share is entitled to one (1) vote on all matters subject to shareholders’ vote.

If your Shares are held in the name of a broker, bank or other nominee, your broker, bank or other nominee will not vote your Shares in the absence of specific instructions from you. These non-voted Shares are referred to as “broker non-votes.”

Appraisal Rights of Shareholders and ADS Holders (page 70)

Shareholders who elect to dissent from the Share Purchase will have the right to seek appraisal and payment of the fair value of their Shares if the Share Purchase is completed, but only if they deliver to the Company, before or during the extraordinary general meeting at which the vote is taken, a written objection or an oral objection that has been put into the record to the Share Purchase and subsequently comply with all procedures and requirements of Article 12 of the ROC M&A Act for the exercise of appraisal rights. The appraised fair value of your Shares as determined under that statute could be more than, the same as, or less than the Share Purchase consideration you would receive pursuant to the Joint Share Exchange Agreement if you do not exercise appraisal rights with respect to your Shares.

ADS HOLDERS WILL NOT HAVE THE RIGHT TO SEEK APPRAISAL AND PAYMENT OF THE FAIR VALUE OF THE SHARES UNDERLYING THEIR ADSs. THE ADS DEPOSITARY WILL NOT ATTEMPT TO PERFECT ANY DISSENTERS’ RIGHTS WITH RESPECT TO ANY OF THE SHARES THAT IT HOLDS, EVEN IF AN ADS HOLDER REQUESTS THE ADS DEPOSITARY TO DO SO. ADS HOLDERS WISHING TO EXERCISE APPRAISAL RIGHTS MUST SURRENDER THEIR ADSs TO THE ADS DEPOSITARY, PAY THE ADS DEPOSITARY’S FEES REQUIRED FOR THE CANCELLATION OF THE ADSs AND PROVIDE INSTRUCTIONS FOR THE REGISTRATION OF THE CORRESPONDING SHARES BEFORE THE CLOSE OF BUSINESS IN NEW YORK CITY ON , 2017, AND BECOME HOLDERS OF SHARES BY THE CLOSE OF BUSINESS IN TAIWAN ON THE SHARE RECORD DATE. THEREAFTER, SUCH FORMER ADS HOLDERS MUST COMPLY WITH THE PROCEDURES AND REQUIREMENTS FOR EXERCISING APPRAISAL RIGHTS WITH RESPECT TO THE SHARES UNDER ARTICLE 12 OF THE ROC M&A ACT.

We encourage you to read the section of this proxy statement entitled “Dissenters’ Rights” as well as Annex E to this proxy statement carefully and to consult your Taiwan legal counsel if you desire to exercise your appraisal rights.

Purposes and Effects of the Share Purchase (page 38 and 63)

The purpose of the Share Purchase is to enable HoldCo to acquire 100% control of the Company in a transaction whereby the holders of the Shares and ADSs will exchange their Shares and ADSs for the Final Per Share Consideration and the Final Per ADS Consideration, respectively. Please see “Special Factors—ASE’s Purposes of and Reasons for the Share Purchase” beginning on page 38 for additional information.

The Shares are currently listed on the TWSE under the stock code “2325.” ADSs representing the Shares are currently listed on the Nasdaq Global Market (“NASDAQ”) under the symbol “SPIL.” It is expected that, following the completion of the Share Purchase, the Company will cease to be a publicly-traded company and will instead become a private company beneficially owned by HoldCo. Following the completion of the Share Purchase, our Shares and ADSs will no longer be listed on any securities exchange or quotation system, including the Taiwan Stock Exchange and NASDAQ, and price quotations with respect to sales of the Shares and the ADSs in the public market will no longer be available. Please see “Special Factors—Effects of the Share Purchase on the Company” beginning on page 63 for additional information.

Plans for the Company after the Share Purchase (Page 64)

Following the completion of the Share Purchase, it is anticipated that the Company will continue to conduct its operations substantially as they are currently being conducted, except that it will cease to be a publicly-traded company and will instead be a wholly-owned subsidiary of HoldCo. The Company will no longer be subject to the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or NASDAQ compliance and reporting requirements and the related direct and indirect costs and expenses.

ASE has advised the Company that, except for the transactions contemplated by the Joint Share Exchange Agreement and transactions already under consideration by the Company, ASE does not have any current plans, proposals or negotiations that relate to or would result in any of the following:

| • |  | an extraordinary corporate transaction, such as a merger, reorganization, liquidation or relocation of any material operations, involving the Company or any of its subsidiaries;

| • |  | the sale or transfer of a material amount of the assets of the Company or any of its subsidiaries; or

| • |  | any other material changes in the Company’s business, including with respect to the Company’s corporate structure or business.

Please see “Special Factors—Plans for the Company after the Share Purchase” beginning on page 64 for additional information.

Review Conclusion of the Special Committee and Recommendation of Our Board (Page 33)

The Special Committee unanimously determined that the terms and conditions of the Joint Share Exchange Agreement are reasonable and fair to the Company and submitted its review minutes and conclusions to the Board for consideration. Based in part on the unanimous determination of the Special Committee, our Board determined that it is fair to and in the best interests of the Company, and declared it advisable, that the Company should approve and, as the case may be, enter into the Joint Share Exchange Agreement and the Share Purchase, and approved the execution, delivery and performance by the Company of the Joint Share Exchange Agreement and the completion of the transactions contemplated thereby, including the Share Purchase. ACCORDINGLY, OUR BOARD OF DIRECTORS RECOMMENDS THAT YOU VOTE FOR THE APPROVAL OF THE JOINT SHARE EXCHANGE AGREEMENT AND THE APPROVAL OF THE TRANSACTIONS CONTEMPLATED BY THE JOINT SHARE EXCHANGE AGREEMENT, INCLUDING THE SHARE PURCHASE.

The primary benefits of the Share Purchase to the Company’s shareholders and ADS holders (other than ASE) include, without limitation, the following:

| • |  | the Original Per Share Consideration (or the US Dollar equivalent of NT$275.0 per ADS (the “Original Per ADS Consideration”)). The Original Per Share Consideration and the Original Per ADS Consideration represent an 8.9% and 12.3% premium over the Company’s closing price of NT$50.5 per share and $7.52 per ADS, respectively, as quoted by the TWSE and NASDAQ, respectively, on May 25, 2016, the last trading day (the “Last Trading Day”) prior to the Company’s announcement on May 26, 2016 that a non-binding share purchase memorandum of understanding was entered into by and between the Company and ASE (the “Share Purchase MOU”). The Original Per Share Consideration and the Original Per ADS Consideration also represents a premium of 17.4% and 19.7% over the Company’s one-month volume-weighted average price of NT$46.86 per Share and $7.06 per ADS, respectively, and a premium of 10.3% and 11.6% over the Company’s three-month volume-weighted average price of NT$49.85 per Share and $7.57 per ADS, respectively, in each case as quoted by the TWSE and NASDAQ, respectively, on the Last Trading Day.

| • |  | the all-cash Share Purchase consideration, which will allow our shareholders and ADS holders to promptly realize liquidity for their investment and provide them with certainty of the value of their Shares or ADSs.

7

The primary detriments of the Share Purchase to the Company’s shareholders and ADS holders (other than ASE) include, without limitation, the following:

| • |  | the shareholders and ADS holders (other than ASE) will have no ongoing equity participation in the Company following the Share Purchase, and they will cease to participate in our future earnings or growth, if any, or to benefit from increases, if any, in the value of the Shares, and will not participate in any potential future sale of the Company to a third party or any potential recapitalization of the Company, which could include a dividend to shareholders.

| • |  | the inability to participate in any potential future sale of part or all of the Company following the Share Purchase to one or more purchasers at a valuation higher than that being paid in the Share Purchase.

| • |  | the taxability of an all cash transaction to our shareholders and ADS holders who are U.S. Holders (as defined under “Material U.S. Federal Income Tax Considerations”) for U.S. federal income tax purposes.

The foregoing summary of information and factors considered by the Special Committee and our Board is not intended to be exhaustive. For a more detailed discussion of the material factors considered by the Special Committee in determining that the terms and conditions of the Joint Share Exchange Agreement are reasonable and fair to the Company and by our Board in determining to recommend the approval of the Joint Share Exchange Agreement and the approval of the transactions contemplated by the Joint Share Exchange Agreement and in determining that it is fair to and in the best interests of the Company that the Company should approve and, as the case may be, enter into the Joint Share Exchange Agreement and the Share Purchase, see “Special Factors—Reasons for the Share Purchase, Review Conclusion of the Special Committee and Recommendation of Our Board” beginning on page 33 and “Special Factors—Effects of the Share Purchase on the Company—Primary Benefits and Detriments of the Share Purchase” beginning on page 63 for additional information. The foregoing summary is qualified in its entirety by reference to these sections.

Position of ASE as to Fairness of the Share Purchase (Page 39)

ASE believes that the Share Purchase is substantively and procedurally fair to the Company’s other shareholders and ADS holders. Its belief is based upon the factors discussed under the caption “Special Factors—Position of ASE as to Fairness of the Share Purchase” beginning on page 39.

ASE is making the statements included in this paragraph solely for the purpose of complying with the requirements of Rule 13e-3 and related rules under the Exchange Act. The views of ASE as to the fairness of the merger are not intended to be and should not be construed as a recommendation to any shareholder of the Company as to how that shareholder should vote on the proposal to approve the Joint Share Exchange Agreement and the transactions contemplated by the Joint Share Exchange Agreement, including the Share Purchase.

Financing of the Share Purchase (Page 87)

HoldCo intends to fund the Share Purchase, which is an aggregate amount of approximately NT$173.16 billion, with a combination of ASE’s cash on hand and debt financing. Subject to the amount of cash on hand at the time when ASE arranges for financing, ASE may arrange bank loans up to NT$173 billion with a combination of a syndication loan of NT$120 billion and a short-term bridge loan of NT$53 billion. In a highly confident letter dated November 7, 2016 issued by Citibank Taiwan Limited (“Citibank”) to ASE, Citibank stated that it is highly confident of its ability to arrange debt facilities for the Share Purchase up to an amount of US$3.8 billion equivalent, subject to the terms and conditions set forth in that letter. In another highly confident letter dated November 16, 2016 issued by DBS Bank Ltd., Taipei Branch (“DBS”) to ASE, DBS stated that it is confident of its ability to arrange debt facilities for the Share Purchase up to an amount of NT$53 billion, subject to the terms and conditions set forth in that letter. In addition, ASE may enter into other arrangements or transactions, including through a capital increase in cash to reduce the amount of bank loans on or prior to the Effective Time.

Share Ownership of ASE (Page 67)

Interests of the Company’s Executive Officers and Directors in the Share Purchase (Page 68)

In considering the recommendations of the Board, the Company’s shareholders should be aware that certain of the Company’s directors and executive officers have interests in the transaction that are different from, and/or in addition to, the interests of the Company’s shareholders generally. These interests include, among others:

| • |  | continuation of service of the directors and the executive officers of the Company in positions that are substantially similar to their current positions;

| • |  | independent operations of the Company after the Effective Time: After the Share Purchase is completed, the Company will be allowed to continue to maintain its independent operations, including:

| • |  | the Company’s entire operations shall be managed by the Board, which shall have independent decision power in respect of the Company’s organizational documents, personnel, payroll or welfare systems, financial budgets, audit, technology research and development, operations, marketing and other matters; and

| • |  | any matter regarding the Company’s rights and obligations shall be conducted by its Board or under its authorization, and the operation of its businesses shall also be conducted by its Board or under its directions;

10

| • |  | guarantee of the benefits and rights of the Company’s employees subsequent to the Effective Time:

| • |  | the Company’s employees will be retained and the existing employee benefits, working conditions and personnel regulations as of the date of the Joint Share Exchange Agreement will continue to apply to the employees;

| • |  | HoldCo will reserve a portion of its employee stock options for the Company’s employees when HoldCo issues new employee stock options, and the Board may reasonably adjust the Company’s employee compensation and benefits by reference to ASE’s employee compensation and benefits; and

| • |  | HoldCo will determine the terms of the employee stock options plan and the portion to be reserved for the Company’s employees based on the number of employees, each employee’s contribution, performance results and profitability of HoldCo’s future subsidiaries.

As of the date of this proxy statement, the Company’s directors and executive officers (as set forth in “Security Ownership of Certain Beneficial Owners and Management of the Company” beginning on page 98), as a group, beneficially own an aggregate of [116,866,101] Shares, representing approximately [3.75]% of the total Shares that will be purchased as part of the Share Purchase. The maximum amount of cash payments our directors and executive officers may receive in respect of their Shares and options if the Share Purchase is consummated is approximately $[197.5] million. Please see “Special Factors—Interests of Certain Persons in the Share Purchase” beginning on page 67 for additional information.

The Special Committee and our Board were aware of these potential conflicts of interest and considered them, among other matters, in reaching their decisions and recommendations with respect to the Joint Share Exchange Agreement and related matters. Please see “Special Factors—Interests of Certain Persons in the Share Purchase” beginning on page 67 for additional information.

No Solicitation by the Company of Acquisition Proposals (see page 85)

Under the terms of the Joint Share Exchange Agreement, the Company agreed not to offer, agree, enter into or sign with any third party any contract, agreement or other arrangements in respect to certain alternative transactions, subject to certain exceptions as described in the section entitled “The Joint Share Exchange Agreement — Pre-Closing Covenants of the Company — Superior Proposals.”

| • |  | no order (or agreement with the FTC) is in effect and enforceable prohibiting, enjoining or rendering illegal the consummation of the Share Purchase, and no law shall have been enacted or enforced after the date the Joint Share Exchange Agreement was executed rendering illegal or prohibiting the consummation of the Share Purchase; provided that the enforcement of an order or law shall not include the decision by a governmental entity to extend the waiting period or initiate an investigation under antitrust laws or other applicable law.

12

ASE Board does not intend to waive (where capable of waiver by ASE) any of these or any other conditions unless it determines that the Share Purchase is in the best interest of ASE and ASE shareholders despite the condition(s) not being satisfied in whole or in part.

In addition, the expected timing for the completion of the Share Purchase may be impacted by other conditions described in this proxy statement.

Termination of the Joint Share Exchange Agreement (see page 89)

The Joint Share Exchange Agreement may be terminated prior to the Effective Time by either ASE or the Company if any of the following occurs:

| • |  | a law, judgment, court order or administrative decision issued by a competent authority restricts or prohibits the consummation of the Share Purchase, and such restriction or prohibition has been confirmed and cannot be remedied by amending the Joint Share Exchange Agreement; or

| • |  | the Joint Share Exchange Agreement and Share Purchase are not approved by ASE’s shareholders or the Company’s shareholders at their respective shareholder meetings.

The Joint Share Exchange Agreement may also be terminated at any time prior to the Effective Time by ASE if the Company has breached or failed to perform any of its representations, warranties, undertakings or obligations under the Joint Share Exchange Agreement and such breach (i) leads to the failure to satisfy the conditions to the consummation of the Share Purchase, (ii)is by its nature not curable or is not cured by the Company within 30 business days of receiving written notice of such breach, and (iii) is not waived in writing by ASE.

The Joint Share Exchange Agreement may also be terminated at any time prior to the Effective Time by the Company if ASE has breached or failed to perform any of its representations, warranties, undertakings or obligations under the Joint Share Exchange Agreement and such breach (i) leads to the failure to satisfy the conditions to the consummation of the Share Purchase, (ii)is by its nature not curable or is not cured by ASE within 30 business days of receiving written notice of such breach, and (iii) is not waived in writing by the Company.

If the Share Purchase is not consummated on or before the Long Stop Date, the Joint Share Exchange Agreement will automatically terminate at midnight on the day immediately following the Long Stop Date.

Termination Fees Relating to the Share Purchase (see page 85)

The Company may be required to pay a termination fee of NT$17 billion if the Joint Share Exchange Agreement is terminated due to the Company’s acceptance of a Superior Proposal (as defined in the Joint Share Exchange Agreement and further explained under the section entitled “The Joint Share Exchange Agreement — Pre-Closing Covenants and Agreements — Superior Proposals” beginning on page 85). See the section entitled “The Joint Share Exchange Agreement — Pre-Closing Covenants of the Company — Superior Proposals” for a more complete description of the circumstances under which the Company may be required to pay ASE a termination fee.

Remedies and Liquidated Damages (see page 67)

Upon the occurrence of certain prescribed material events of default, in addition to any right of termination and claims for expenses, the non-defaulting party will also be entitled to liquidated damages in the amount of NT$8.5 billion from the defaulting party, subject to adjustments for contributory negligence by the non-defaulting party. Please see the section entitled “The Joint Share Exchange Agreement — Termination and Events of Default” for a more complete description of the circumstances under which ASE or the Company may be required to pay the other party liquidated damages.

Material U.S. Federal Income Tax Considerations (Page 99)

The receipt of cash pursuant to the Share Purchase or through the exercise of dissenters’ rights will be a taxable transaction for U.S. federal income tax purposes and may also be a taxable transaction under applicable state, local and other tax laws. Please see “Material U.S. Federal Income Tax Considerations” beginning on page 99 for additional information. The tax consequences of the Share Purchase or the exercise of dissenters’ rights to you will depend upon your personal circumstances. You should consult your tax advisors for a full understanding of the U.S. federal, state, local, foreign and other tax consequences of the Share Purchase to you.

Material Taiwan Income Tax Considerations (Page 103)

Whether or not the receipt of cash pursuant to the Share Purchase or through the exercise of dissenters’ rights will be treated as a taxable transaction for ROC income tax purposes and/or ROC securities transaction tax purposes depends on your residency for tax purposes and the type of securities you are holding. For Non-ROC Holders (as defined in “Material Taiwan Tax Considerations” beginning on page 103), capital gains on transactions in common shares are currently exempt from income tax. Transfers of ADSs are not regarded as a sale of an ROC security and, as a result, any gains on such transactions are not subject to ROC income tax. In addition, a securities transaction tax, at a rate of 0.3% of the sale proceeds, will be withheld upon a sale of common shares in the ROC. However, transfers of ADSs are not subject to ROC securities transaction tax. Please see “Material Taiwan Income Tax Considerations” beginning on page 103 for additional information. The tax consequences of the Share Purchase will depend upon your personal circumstances. You should consult your tax advisors for a full understanding of the ROC tax and other tax consequences of the Share Purchase to you.

Regulatory Approvals Required to Complete the Share Purchase (Page 70)

The completion of the Share Purchase is subject to obtaining antitrust and other regulatory approvals in certain jurisdictions, as noted below. ASE and the Company submitted required materials to the TFTC on July 29, 2016 and TFTC issued a no objection letter in respect of the Share Purchase on November 16, 2016. In addition, the FTC has issued a subpoena and civil investigative demand relating to the proposed combination. ASE and the Company are fully cooperating with such investigation. There can be no assurance as to if and when regulatory approvals will be obtained in the PRC, if and when the FTC will complete its investigation without seeking an injunction, or the conditions or limitations that such regulatory authorities may seek to impose. Please see the section entitled “Special Factors — Regulatory Approvals Required to Complete the Share Purchase.”

Accounting Treatment of the Share Purchase (Page 69)

The Company will account for the Share Purchase as a transaction between the Company’s shareholders under the International Financial Reporting Standards as issued by the International Accounting Standards Board (“IFRS”) or the International Financial Reporting Standards as adopted in Taiwan (“Taiwan-IFRS”). From the perspective of the Company’s consolidated financial statements, no special accounting treatment will be applied as a result of the Share Purchase.

14

Market Price of the Shares and the ADSs (Page 71)

The closing prices of the Shares and the ADSs on the TWSE and NASDAQ, respectively, on the Last Trading Day, were NT$50.5 per Share and US$7.52 per ADS. The Original Per Share Consideration (or the Original Per ADS Consideration) to be paid in the Share Purchase represents a premium of approximately 8.9% and 12.3% over the respective closing prices.

Fees and Expenses (Page 69)

Whether or not the Share Purchase is completed, all costs and expenses incurred in connection with the Joint Share Exchange Agreement and the transactions contemplated thereby will be paid by the party incurring such costs and expenses except as otherwise provided in the Joint Share Exchange Agreement.

QUESTIONS AND ANSWERS ABOUT THE EXTRAORDINARY GENERAL MEETING AND THE SHARE PURCHASE

The following questions and answers address briefly some questions you may have regarding the extraordinary general meeting and the Share Purchase. These questions and answers may not address all questions that may be important to you as a shareholder of the Company. Please refer to the more detailed information contained elsewhere in this proxy statement, the annexes to this proxy statement and the documents referred to or incorporated by reference in this proxy statement.

Q: | What is the proposed transaction?

A: | The Share Purchase is a transaction pursuant to which a holding company, HoldCo, will be formed at the Effective Time and HoldCo will acquire (i) all Shares of the Company and (ii) issue new shares to the shareholders of ASE in exchange for all the ASE Shares. Once the Joint Share Exchange Agreement is approved by the shareholders of the Company and the other closing conditions under the Joint Share Exchange Agreement have been satisfied or waived, HoldCo will acquire all the Shares of the Company, and the Company will continue its operations as a privately held company owned solely by HoldCo. As a result of the Share Purchase, the Shares will no longer be listed on the Taiwan Stock Exchange, the ADSs will no longer be listed on NASDAQ, and the Company will cease to be a publicly-traded company.

Q: | What will I receive in the Share Purchase?

A: | If you own Shares and the Share Purchase is completed, you will be entitled to the Final Per Share Consideration, without interest and net of any applicable taxes, for each Share you own as of the Effective Time (unless you validly exercise and have not effectively withdrawn or lost your appraisal rights under Article 12 of the ROC M&A Act with respect to the Share Purchase, in which case you will be entitled to the appraised fair value or other agreed value of each Share pursuant to Article 12 of the ROC M&A Act, without interest and net of any applicable withholding tax).

If you own ADSs and the Share Purchase is completed, you will be entitled to receive, through the ADS Depositary, the Final Per ADS Consideration, without interest and net of any applicable withholding taxes, for each ADS you own as of the Effective Time unless you (a) surrender your ADS to the ADS Depositary, pay the ADS Depositary’s fees required for the cancellation of ADSs and provide instructions for the registration of the corresponding Shares before the close of business in New York City on , 2017 and become a holder of Shares by the close of business in Taiwan on the Share Record Date and (b) comply with the procedures and requirements for exercising appraisal rights for the Shares under Article 12 of the ROC M&A Act.

Please see “Material U.S. Federal Income Tax Considerations” and “Material Taiwan Tax Considerations” beginning on page 99 for a more detailed description of the tax consequences of the Share Purchase. You should consult your own tax advisor for a full understanding of how the Share Purchase will affect your U.S. federal, state, local, foreign and other taxes.

16

Q: | After the Share Purchase is completed, how will I receive the Share Purchase consideration for my Shares (not including Shares represented by ADSs)?

A: | If you are a registered holder of Shares, within three (3) business days after the Effective Time, HoldCo will pay the Share Purchase consideration to the Company’s stock agent, who will send you, as soon as practicable but no later than [ ] business days after the Effective Time, the Final Per Share Consideration in cash, without interest and net of any applicable withholding taxes, for each Share you held according to the registration information in the shareholder roster of the Company immediately before the Effective Time, unless you validly exercised and have not effectively withdrawn or lost your appraisal rights in accordance with Article 12 of the ROC M&A Act.

Q: | After the Share Purchase is completed, how will I receive the cash for my ADSs?

A: | If your ADSs are represented by certificates, also referred to as American depositary receipts (“ADRs”), unless you have surrendered your ADRs to the ADS Depositary for cancellation prior to the Effective Time, upon your surrender of the ADRs (or an affidavit and indemnity of loss in lieu of the ADRs) together with a duly completed letter of transmittal (which will be supplied to you by the ADS Depositary after the effective time), the ADS Depositary will send you a check for the Final Per ADS Consideration, without interest and net of any applicable withholding taxes, for each ADS represented by the ADRs, in exchange for the cancellation of your ADRs after the completion of the Share Purchase. The per ADS exchange consideration may be subject to backup withholding taxes if the ADS Depositary has not received from you a properly completed and signed U.S. Internal Revenue Service Form W-8 or W-9.

In the event of a transfer of ownership of ADSs that is not registered in the register of ADS holders maintained by the ADS Depositary, the check for any cash to be exchanged upon cancellation of the ADSs will be issued to such transferee only if the ADRs, if applicable, are presented to the ADS Depositary, accompanied by all documents reasonably required to evidence and effect such transfer and to evidence that any applicable ADS transfer taxes have been paid or are not applicable. The per ADS exchange consideration may be subject to backup withholding taxes if the ADS Depositary has not received from the transferee a properly completed and signed U.S. Internal Revenue Service Form W-8 or W-9.

If your ADSs are held in “street name” by your broker, bank or other nominee, you will not be required to take any action to receive the Share Purchase consideration for your ADSs as the ADS Depositary will arrange for the surrender of the ADSs and the remittance of the per ADS exchange consideration with The Depository Trust Company (the clearance and settlement system for the ADSs) for distribution to your broker, bank or nominee on your behalf. If you have any questions concerning the receipt of the per ADS exchange consideration, please contact your broker, bank or nominee.

Q: | When and where will the extraordinary general meeting be held?

A: | The extraordinary general meeting will take place on , 2017, at a.m. (Taipei time) at Taichung Industrial Park Service Center Administrative Building, Floor 1, Conference Room 101, No. 2, Gongyecyu 5th Road, Situn District, Taichung City, Taiwan.

Q: | What matters will be voted on at the extraordinary general meeting?

A: | You will be asked to consider and vote on the following proposals:

| • |  | to approve the Joint Share Exchange Agreement and the transactions contemplated by the Joint Share Exchange Agreement, including the Share Purchase; and

17

Q: | What vote of our shareholders is required to approve the Joint Share Exchange Agreement?

A: | The only vote of the holders of any class or series of share capital of the Company necessary to approve and adopt the Joint Share Exchange Agreement is the affirmative vote of shareholders representing (a) a simple majority of the voting power of the Shares present and voting in person or by proxy as a single class at the extraordinary general meeting at which shareholders representing two-thirds or more of the total number of the issued and outstanding Shares are present, or (b) two-thirds or more of the voting power of the Shares present and voting in person or by proxy as a single class at the extraordinary general meeting of the Company at which shareholders representing less than two-thirds but more than a simple majority of the total number of the issued and outstanding Shares are present. Each Share is entitled to one (1) vote on all matters subject to the shareholders’ vote. At the close of business in Taiwan on the Share Record Date, [265,676,800] Shares are expected to be outstanding and entitled to vote at the extraordinary general meeting.

Q: | How does the Board recommend that I vote on the proposals?

A: | Having carefully considered all the relevant factors and upon the unanimous determination of the Special Committee, our Board unanimously recommends that you vote:

| • |  | FOR the proposal to approve the Joint Share Exchange Agreement and the transactions contemplated by the Joint Share Exchange Agreement, including the Share Purchase; and

| • |  | FOR the proposal to authorize the Designated Persons to do all things necessary to give effect to the Joint Share Exchange Agreement.

You should read “Special Factors—Reasons for the Share Purchase, Review Conclusion of the Special Committee and Recommendation of Our Board” beginning on page 33 for a discussion of the factors that the Special Committee considered in determining that the terms and conditions of the Joint Share Exchange Agreement are fair and reasonable and the Board considered in deciding to recommend the approval of the Joint Share Exchange Agreement. In addition, in considering the determination of the Special Committee and the recommendation of the Board with respect to the Joint Share Exchange Agreement, you should be aware that some of the Company’s directors and executive officers have interests in the Share Purchase that are different from, or in addition to, the interests of our shareholders generally. See “Special Factors—Interests of Certain Persons in the Share Purchase” beginning on page 67.

Q: | Who is entitled to vote at the extraordinary general meeting?

A: | The Share Record Date is , 2017. Only shareholders entered in the shareholder registry of the Company at the close of business in Taiwan on the Share Record Date or their proxy holders are entitled to vote at the extraordinary general meeting or any adjournment thereof. The ADS Record Date is , 2017. Only ADS holders of the Company at the close of business in New York City on the ADS Record Date are entitled to instruct the ADS Depositary to vote at the extraordinary general meeting. Alternatively, you may vote at the extraordinary general meeting if you cancel your ADSs by the close of business in New York City on , 2017 and become a holder of Shares by the close of business in Taiwan on the Share Record Date. If you wish to cancel your ADSs, please see below for additional information or see “The Extraordinary General Meeting—Procedures for Voting—ADSs” beginning on page 75.

18

Q: | What constitutes a quorum for the extraordinary general meeting?

A: | The presence, in person, by proxy or by corporate representative, of shareholders holding a simple majority of the issued and outstanding Shares that are entitled to vote on the record date will constitute a quorum for the extraordinary general meeting.

Q: | When do you expect the Share Purchase to be completed?

A: | We are working toward completing the Share Purchase as quickly as possible and currently expect the Share Purchase to close in the [second quarter of 2017]. In order to complete the Share Purchase, we must obtain shareholder approval of the Share Purchase at the extraordinary general meeting and the other closing conditions under the Joint Share Exchange Agreement, including, without limitation, approvals of or no objections to anti-trust approval authorities in Taiwan, the United States and the PRC, must be satisfied or waived in accordance with the Joint Share Exchange Agreement.

Q: | What happens if the Share Purchase is not completed?

A: | If the Joint Share Exchange Agreement is not approved by the shareholders or if the Share Purchase is not completed for any other reason, shareholders will not receive any payment for their Shares or ADSs in connection with the Share Purchase nor will the holders of any share options receive payment pursuant to the Joint Share Exchange Agreement. Instead, the Shares will continue to be listed and traded on the TWSE and the ADSs will continue to be listed and traded on NASDAQ, provided that the Company continues to meet the respective listing requirements of the stock exchanges, and the Company will remain subject to SEC reporting obligations. Therefore, the Company’s shareholders will continue to be subject to similar risks and opportunities as they currently are with respect to their ownership of our Shares or ADSs. Accordingly, if the Share Purchase is not completed, there can be no assurance as to the effect of these risks and opportunities on the future value of your Shares or ADSs, including the risk that the market price of the ADSs may decline to the extent that the current market price reflects a market assumption that the Share Purchase will be completed.

Q: | What do I need to do now?

A: | We urge you to read this proxy statement carefully, including its annexes, exhibits, attachments and the other documents referred to or incorporated by reference herein and to consider how the Share Purchase affects you as a shareholder. After you have done so, please vote as soon as possible.

Q: | How do I vote if my Shares are registered in my name?

A: | If Shares are registered in your name (that is, you do not hold ADSs) as of the Share Record Date for shareholder voting, you should simply indicate on your proxy card how you want to vote, and sign and mail your proxy card in the accompanying return envelope as soon as possible, but in any event no later than five (5) days before the date of the extraordinary general meeting, so that your Shares will be represented and may be voted at the extraordinary general meeting.

19

You may also vote electronically through the shareholder voting platform maintained by Taiwan Depository and Clearing Corporation (the “Electronic Voting Platform”) no later than two (2) days prior to the date of the extraordinary general meeting (the “Electronic Voting Period”) by accessing the following website: https://www.stockvote.com.tw/evote/login/shareholder.html. You can log into the Electronic Voting Platform with (i) your identity card number or your unified business number and (ii) an eligible electronic certificate, such as a securities firm online order placement certificate, natural person certificate or industrial and commercial certificate and proceed in accordance with the instructions provided therein. Voting electronically will not deprive you of your right to attend the extraordinary general meeting and vote in person, provided that you withdraw your electronic vote no later than two (2) days prior to the date of the extraordinary general meeting. If you do not withdraw your vote before such deadline and attend the extraordinary general meeting to vote in person, your vote exercised electronically will prevail.

Alternatively, if you do not submit a proxy card or vote electronically, you can attend the extraordinary general meeting and vote in person. If your Shares are held by your broker, bank or other nominee, please see below for additional information.

Q: | How do I vote if I own ADSs?

A: | If you own ADSs as of the close of business in New York City on the ADS Record Date, you cannot vote at the meeting directly, but you may instruct the ADS Depositary (as the holder of the Shares underlying your ADSs) how to vote the Shares underlying your ADSs by completing and signing the ADS voting instruction card and returning it in accordance with the instructions printed on it as soon as possible but, in any event, so as to be received by the ADS Depositary no later than 12:00 p.m. (New York City time) on , 2017. However, please be aware that the ADS Depositary, as the record holder of the Shares represented by ADSs, will NOT vote the Shares it holds on deposit at the extraordinary general meeting in accordance with the individual voting instructions it receives. Instead, the ADS Depositary will vote ALL the Shares it holds on deposit at the extraordinary general meeting as follows:

| • |  | if holders of at least 51% of the ADSs outstanding at the close of business in New York City on the ADS Record Date, instruct the ADS Depositary to vote in the same manner regarding a resolution, the ADS Depositary will appoint the Voting Representative to vote ALL the Shares represented by the ADSs outstanding in the manner so instructed.

| • |  | if the ADS Depositary does not receive instructions from holders of at least 51% of the ADSs outstanding at the close of business in New York City on the ADS Record Date, to vote in the same manner regarding a resolution, the ADS Depositary itself will not provide any voting instruction and instead will appoint the Voting Representative to vote ALL the Shares represented by the ADSs outstanding as the Voting Representative deems appropriate, which may not be in your best interest.

Alternatively, you may vote at the extraordinary general meeting if you cancel your ADSs prior to the close of business in New York City on , 2017 and become a holder of Shares by the close of business in Taiwan on the Share Record Date. If you hold your ADSs through a financial intermediary such as a broker, you must rely on the procedures of the financial intermediary through which you hold your ADSs if you wish to vote. If your ADSs are held by your broker, bank or other nominee, see below.

20

If you wish to cancel your ADSs, you need to make arrangements to deliver your ADSs to the ADS Depositary for cancellation prior to the close of business in New York City on , 2017 together with (a) delivery instructions for the corresponding Shares (name and address of the person who will be the registered holder of Shares), and (b) payment of the ADS cancellation fees (US$0.05 per ADS to be cancelled) and any applicable taxes. If you hold your ADSs in a brokerage, bank or nominee account, please contact your broker, bank or nominee to find out what actions you need to take to instruct the broker, bank or nominee to cancel the ADSs on your behalf. Upon cancellation of the ADSs, the ADS Depositary will arrange for JPMorgan Chase Bank, N.A., Taipei Branch, the custodian holding the Shares, to transfer registration of the Shares to the former ADS holder. If after registration of Shares in your name you wish to receive a certificate evidencing the Shares registered in your name, you will need to request the registrar of the Shares to issue and mail a certificate to your attention.

As of the date hereof, the Company is not aware of any substantial opposition to any matter to be voted on at the extraordinary general meeting and does not believe that any such matter will have a material adverse impact on the rights of the Company’s shareholders.

Q: | If my Shares or ADSs are held in a brokerage account, will my broker vote my Shares on my behalf?

A: | Your broker, bank or other nominee will only vote your Shares on your behalf or give voting instructions with respect to the Shares underlying your ADSs if you instruct it on how to vote. Therefore, it is important that you promptly follow the directions provided by your broker, bank or nominee regarding how to instruct it to vote your Shares. If you do not instruct your broker, bank or other nominee how to vote your Shares that it holds, those Shares may not be voted.

Q: | What will happen if I abstain from voting or fail to vote on the proposal to approve the Joint Share Exchange Agreement?

A: | If you abstain from voting, fail to cast your vote in person, fail to complete and return your proxy card in accordance with the instructions set forth on the proxy card, or fail to give voting instructions to your broker, dealer, commercial bank, trust company or other nominee, your vote will not be counted.

However, if you hold ADSs and do not give the ADS Depositary voting instructions in a timely manner, under the deposit agreement, the ADS Depositary will appoint the Voting Representative to vote ALL the Shares represented by the ADSs outstanding in the manner as instructed by at least 51% of the ADSs outstanding, or as the Voting Representative deems appropriate if the ADSs Depositary does not receive instructions to vote in the same manner by at least 51% of the ADS outstanding.

As of the date hereof, the Company is not aware of any substantial opposition to any matter to be voted on at the extraordinary general meeting and does not believe any such matter will have a material adverse impact on the rights of the Company’s shareholders.

21

Q: | May I change my vote?

A: | Yes.

If you previously delivered a valid proxy to the Company, you may change your vote in one of two ways:

| • |  | first, you may attend the extraordinary general meeting and vote in person. Attendance, by itself, will not revoke a proxy. It will only be revoked if the shareholder files a written notice of revocation with the Company no later than two (2) days before the date of the extraordinary general meeting. Any written notice revoking a proxy should be sent to Siliconware Precision Industries Co., Ltd., No. 123, Sec. 3, Da Fong Road, Tantzu, Taichung, Taiwan, Republic of China, Attention: Eva Chen; or

| • |  | second, you may complete, date and submit a new proxy card, which shall include an explicit statement revoking the previous proxy and bear a later date than the proxy card sought to be revoked to the Company no later than five (5) days prior to the date of the extraordinary general meeting.

If you previously exercised your vote electronically, you may change your vote in one of three ways:

| • |  | first, you may attend the extraordinary general meeting and vote in person. Attendance, by itself, will not revoke an electronic vote. It will only be revoked if you withdraw your electronic vote through the Electronic Voting Platform no later than two (2) days before the date of the extraordinary general meeting;

| • |  | second, you may change your vote by logging into the Electronic Voting Platform no later than two (2) days prior to the date of the extraordinary general meeting; or

| • |  | third, you may complete, date and submit a new proxy card, which shall include an explicit statement revoking the previous electronic vote and bear a later date than the electronic vote sought to be revoked to the Company no later than five (5) days prior to the date of the extraordinary general meeting.

If you hold Shares through a broker, bank or other nominee and have instructed the broker, bank or other nominee to vote your Shares, you must follow directions received from the broker, bank or other nominee to change your instructions.

Holders of our ADSs may revoke their voting instructions by notification to the ADS Depositary in writing at any time prior to 12:00 p.m. (New York City time) on , 2017. A holder of ADSs can do this in one of two ways:

| • |  | first, a holder of ADSs can revoke its voting instructions by written notice of revocation timely delivered to the ADS Depositary.

| • |  | second, a holder of ADSs can complete, date and submit a new ADS voting instruction card to the ADS Depositary bearing a later date than the ADS voting instruction card sought to be revoked.

22

If you hold your ADSs through a broker, bank or nominee and you have instructed your broker, bank or nominee to give ADS voting instructions to the ADS Depositary, you must follow the directions of your broker, bank or nominee to change those instructions.

Q: | What should I do if I receive more than one set of voting materials?

A: | You may receive more than one set of voting materials, including multiple copies of this proxy statement or multiple proxy or voting instruction cards. For example, if you hold your Shares or ADSs in more than one brokerage account, you will receive a separate voting instruction card for each brokerage account in which you hold Shares or ADSs. If you are a holder of record and your Shares or ADSs are registered in more than one name, you will receive more than one proxy card. Please submit each proxy card that you receive.

Q: | Should I send in my share certificates or my ADRs now?

A: | No. After the Share Purchase is completed, you will be sent a form of letter of transmittal with detailed written instructions for exchanging your share certificates for the Share Purchase consideration. Please do not send in your certificates now. Similarly, you should not send in the ADRs that represent your ADSs at this time. Promptly after the Share Purchase is completed, the ADS Depositary will call for the surrender of all ADRs for delivery of the Share Purchase consideration. ADR holders will be receiving a similar form of letter of transmittal and written instructions from the ADS Depositary relating to the foregoing.

All holders of uncertificated Shares and uncertificated ADSs (i.e., holders whose Shares or ADSs are held in book entry) will automatically receive their cash consideration shortly after the Share Purchase is completed without any further action required on the part of such holders.

If your Shares or your ADSs are held in “street name” by your broker, bank or other nominee, you will receive instructions from your broker, bank or other nominee as to how to effect the surrender of your share certificates or ADRs in exchange for the Share Purchase consideration.

Q: | Am I entitled to appraisal rights?

A: | Yes. Shareholders electing to dissent from the Share Purchase will have the right to seek appraisal and payment of the fair value of their Shares if the Share Purchase is completed, but only if they deliver to the Company, before or during the extraordinary general meeting at which the vote is taken, a written objection or an oral objection that has been put into the record to the Share Purchase and they subsequently comply with all procedures and requirements of Article 12 of ROC M&A Act for the exercise of appraisal rights. The fair value of your Shares as determined under that statute could be more than, the same as, or less than the Share Purchase consideration you would receive pursuant to the Joint Share Exchange Agreement if you did not exercise appraisal rights with respect to your Shares.

ADS holders will not have the right to seek appraisal and payment of the fair value of the Shares underlying their ADSs. The ADS Depositary will not attempt to perfect any dissenters’ rights with respect to any of the Shares that it holds, even if an ADS holder requests the ADS Depositary to do so. ADS holders wishing to exercise appraisal rights must surrender their ADSs to the ADS Depositary, pay the ADS Depositary’s fees required for such surrender and provide instructions for the registration of the corresponding Shares before the close of business in New York City on , 2017, and become registered holders of Shares by the close of business in Taiwan on the Share Record Date. Thereafter, such former ADS holders must comply with the procedures and requirements for exercising dissenter and appraisal rights with respect to the Shares under Article 12 of the ROC M&A Act.

We encourage you to read the section of this proxy statement entitled “Dissenters’ Rights” beginning on page 93 as well as “Annex E—ROC Business Mergers and Acquisitions Act —Article 12” to this proxy statement carefully and to consult your own Taiwan legal counsel if you desire to exercise your appraisal rights.

Q: | If I own ADSs and seek to perfect appraisal rights, how do I convert my ADSs to Shares, and when is the deadline for completing the conversion of ADSs to Shares?

A: | If you own ADSs and wish to exercise appraisal rights, you must surrender your ADSs at the ADS Depositary’s office at 270 Park Ave, New York, NY 10017. Upon your payment of its fees, including the applicable ADS surrender fee (US$0.05 per ADS being cancelled) and any applicable taxes, the ADS Depositary will transfer the Shares and any other deposited securities underlying the ADSs to such ADS holder or a person designated by such ADS holder.

The deadline for surrendering ADSs to the ADS Depositary for these purposes is the close of business in New York City on , 2017.

You must become a registered holder of your shares and lodge a written notice of objection to the Share Purchase prior to the extraordinary general meeting.

Q: | Will any proxy solicitors be used in connection with the extraordinary general meeting?

A: | No. The Company does not plan to engage a proxy solicitor to assist in the solicitation of proxies.

Q: | Do any of the Company’s directors or executive officers have interests in the Share Purchase that may differ from those of other shareholders?

Yes. Some of the Company’s directors or executive officers have interests in the Share Purchase that may differ from those of other shareholders, including the continuation of service of then directors and the executive officers of the Company in positions that are substantially similar to their current positions. Please see “Special Factors—Interests of Certain Persons in the Share Purchase” beginning on page 67 for a more detailed discussion of how some of the Company’s directors and executive officers have interests in the Share Purchase that are different from, or in addition to, the interests of our shareholders generally.

SPECIAL FACTORS

Effects of the Share Purchase

Upon the terms and subject to the conditions of the Joint Share Exchange Agreement, and in accordance with the applicable provisions of the Company Law of the ROC, at the Effective Time, HoldCo will acquire all issued shares of ASE and the Company, and ASE and the Company will become wholly owned subsidiaries of HoldCo concurrently.

The following chart depicts the organizational structure of each of ASE and the Company (“SPIL” stands for the Company for the purpose of the below chart) before the Share Purchase as of the date of this proxy statement and immediately after the Effective Time.

Before the Share Purchase as of the date of this proxy statement:

Immediately after the Effective Time:

Pursuant to the terms and subject to the conditions set forth in the Joint Share Exchange Agreement, at the Effective Time:

| (i) | for the Company’s shareholders:

| • |  | each Share, par value NT$10 per share, issued immediately prior to the Effective Time (including the Company’s treasury shares and the Shares beneficially owned by ASE), will be transferred to HoldCo in consideration for the right to the Final Per Share Consideration, payable by HoldCo in cash in NT dollars, without interest and net of any applicable withholding taxes; and

| • |  | each ADS will be cancelled in exchange for the right to receive through ADS Depositary, the Final Per ADS Consideration, without interest and net of any applicable withholding taxes.

25

The Final Per Share Consideration and the Final Per ADS Consideration will be subject to adjustments if the Company issues shares or pays cash dividends from the date of this proxy statement to the Effective Time, provided, however, that the Final Per Share Consideration and the Final Per ADS Consideration shall not be subject to adjustment if the aggregate amount of the cash dividends distributed by the Company in fiscal year 2017 is less than 85% of its after-tax net profit for fiscal year 2016.

Upon consummation of the Share Purchase, the Company would become a privately held corporation. Accordingly, the Company’s former shareholders would not have the opportunity to participate in the earnings and growth of the Company after the Share Purchase and would not have any right to vote on corporate matters. Similarly, the Company’s former shareholders would not face the risk of losses generated by the Company’s operations or decline in the value of the Company after the Share Purchase. Further, the Shares would be delisted from the TWSE and the ADSs would be delisted from NASDAQ and would become eligible for deregistration under the Exchange Act.

| (ii) | for ASE shareholders:

| • |  | each ASE Share, par value NT$10 per share, issued immediately prior to the Effective Time (including ASE’s treasury shares), will be transferred to HoldCo in consideration for the right to receive 0.5 common shares of Holdco (“Holdco Common Share”); and

| • |  | each ASE ADS, currently representing five ASE Shares, will, after the Effective Time, represent the right to receive 1.25 American depositary shares of HoldCo (“HoldCo ADSs”), each HoldCo ADS representing two HoldCo Common Shares, upon surrender for cancellation to Citibank, N.A. (the “ASE Depositary”) after the Effective Time.

At the Effective Time, HoldCo will acquire all issued shares of ASE. HoldCo would be entitled to all benefits resulting from its 100% ownership of ASE, including all of ASE’s net book value and net income or loss. Similarly, HoldCo would also bear all of the risk of losses generated by ASE’s operations and any decrease in the value of ASE after the Share Purchase. Upon consummation of the Share Purchase, ASE would become a privately held corporation. ASE Shares would be delisted from the TWSE and ASE ADSs would be delisted from NYSE and would become eligible for deregistration under the Exchange Act.

Background of the Share Purchase; Past Contacts; Negotiations

Events leading to the execution of the Joint Share Exchange Agreement described in this “Background of the Share Purchase; Past Contacts; Negotiations” section occurred in various locations that regularly included Taiwan, United States and Hong Kong. As a result, Taiwan Standard Time is used for all dates and times given.

The Board and senior management of the Company have periodically reviewed the Company’s long-term strategic plan with the goal of maximizing shareholder value. As part of this ongoing process, the Board and senior management of the Company also have periodically reviewed potential strategic alternatives that may be available to the Company.

On August 21, 2015, ASE announced that it planned to commence, on August 24, 2015, tender offers at a price of NT$45 per Share and NT$225 per ADS, respectively, for 779,000,000 Shares (including those represented by ADSs), which represented approximately 24.99% of the issued and outstanding share capital of the Company (the “Initial ASE Tender Offers”).

26

On August 24, 2015, ASE commenced the Initial ASE Tender Offers. On the same day, the Company announced that it had (i) formed a review committee (the “Review Committee”) consisting of its independent directors to evaluate the Initial ASE Tender Offers, and (ii) retained J.P. Morgan as its financial advisor, Simpson Thacher & Bartlett (“Simpson Thacher”) as its United States legal counsel and Jones Day as its Taiwan legal counsel.

On August 28, 2015, the Review Committee and the Board separately held a Review Committee meeting and a Board meeting to discuss and evaluate the Initial ASE Tender Offers. Prior to such meetings, J.P. Morgan provided an opinion to the Board, stating that the consideration of NT$45 per Share and NT$225 per ADS were inadequate from a financial point of view. Ding Shuo Certified Public Accountants (“Ding Shuo”) also delivered a fairness opinion to the Company, which valued the Shares and the ADSs at NT$48.91 to NT$60.58 per Share and NT$244.55 to NT$302.90 per ADS. Having considered all the relevant factors, including a review of the opinions of J.P. Morgan and Ding Shuo, both the Review Committee and the Board unanimously concluded that the Initial ASE Tender Offers were inadequate and determined to recommend that the holders of the Shares and ADSs reject the Initial ASE Tender Offers and not tender any Shares or ADSs pursuant to the Initial ASE Tender Offers (the “Company Recommendation to the Initial Tender Offers”).

On the same day, the Company entered into a letter of intent with Hon Hai Precision Industry Co., Ltd. (“Hon Hai”) pursuant to which (i) the Company would issue 840,600,000 Shares in exchange for 359,230,769 common shares issued by Hon Hai, representing approximately 21.24% and 2.20% of the issued and outstanding share capital of the Company and Hon Hai, respectively (the “Hon Hai Share Exchange”), and (ii) the Company and Hon Hai would cooperate on certain commercial matters specified in such letter of intent (the “Hon Hai Commercial Cooperation”).

On the same day, the Company issued a press release and filed a Solicitation/Recommendation Statement on Schedule 14D-9 (as amended, the “First Schedule 14D-9”) with the SEC announcing (i) the Company Recommendation to the Initial Tender Offers and (ii) the proposed Hon Hai Share Exchange and Hon Hai Commercial Cooperation.

The Hon Hai Share Exchange would have required an increase in the authorized but unissued capital of the Company (the “Capital Increase”) and amendments to the Company’s acquisition and disposition procedures (the “By-Law Amendments”), which would have required the approval of the Company’s shareholders at an extraordinary shareholders’ meeting (the “First EGM”). Later that date, the Company held a meeting of the Board, which approved the calling of the First EGM on October 15, 2015, and set a record date of September 15, 2015 for the First EGM, which date was prior to the expiration and closing of the Initial ASE Tender Offers. ASE was therefore not eligible to vote its Shares at the First EGM.

The Initial ASE Tender Offers expired on September 22, 2015. Pursuant to the Initial ASE Tender Offers, there were validly tendered and not validly withdrawn a number of Shares and ADSs representing approximately 36.83% of the issued and outstanding share capital of the Company. On September 23, 2015, ASE accepted for purchase Shares and ADSs representing approximately 24.99% of the issued and outstanding share capital of the Company.

On September 22, 2015, ASE filed an injunction with the Taichung District Court seeking to enjoin the First EGM.

On September 23, 2015 following the expiration of the Initial ASE Tender Offers, , ASE’s Chairman and Chief Executive Officer, Mr. Jason Chang (“Mr. Chang”) met with the Company’s Chairman, Mr. Lin, to express his regret that, due to certain legal limitations, ASE had not been able to discuss the Initial ASE Tender Offers with the Company prior to its commencement. Mr. Chang also stated that the purpose of ASE’s investment was to explore avenues of mutual cooperation in the face of intensifying global competition and industry consolidation and that ASE opposed the proposed Hon Hai Share Exchange.

27

On September 28, 2015 and October 1, 2015, ASE issued open letters to the Company’s shareholders urging them to vote against the proposals to be voted on at the First EGM in connection with the Hon Hai Share Exchange.

On October 1, 2015, pursuant to the Initial ASE Tender Offers, ASE closed its acquisition of, and paid for, 725,749,060 Shares and 10,650,188 ADSs, representing approximately 24.99% of the issued and outstanding share capital of the Company.

Also on October 1, 2015, ASE filed a suit in the Taichung District Court seeking the invalidation of the Board’s resolution convening the First EGM.

On October 2, 2015, the Company formally received a preliminary injunction petition from the Taichung District Court filed by ASE seeking to enjoin the First EGM. Following the receipt of such petition, the Company convened internal meetings and had discussions with its outside counsels.

On October 5, 2015, ASE issued a further open letter to the Company’s shareholders urging them to vote against the proposals to be voted on at the First EGM in connection with the Hon Hai Share Exchange, noting that two leading proxy advisors agreed with ASE’s position.

On October 13, 2015, the Taichung District Court denied ASE’s petition seeking an injunction to enjoin the First EGM.

On October 15, 2015, the Company’s Capital Increase and By-Law Amendments were not approved by its shareholders at the First EGM.

Also on October 15, 2015, the Company filed a suit in the Kaohsiung District Court (the “SPIL Kaohsiung Suit”) against ASE seeking the invalidation of the Initial ASE Tender Offers and the confirmation that ASE did not have the right to be registered as a shareholder in the Company’s shareholder register. On the same day, ASE withdrew its suit seeking the invalidation of the Board’s resolution convening the First EGM. Subsequently, the Kaohsiung District Court revoked the SPIL Kaohsiung Suit on June 27, 2016.

On October 22, 2015 and on November 2, 2015, Mr. Chang sent letters to Mr. Lin reiterating that the purpose of ASE’s investment in the Company was to establish a basis for possible future cooperation and that ASE hoped to discuss and establish specific plans for such cooperation.

On November 4, 2015, Mr. Lin sent a letter to Mr. Chang noting that the Company did not recognize ASE as a shareholder of the Company and requesting that ASE provided a written undertaking prior to any discussions with the Company. The undertaking shall specify that (i) if ASE became a shareholder of the Company, ASE would maintain its financial investor status, and would not intervene, participate in or interfere with the Company’s business operations, and would not nominate any person for appointment as a director of the Company, and (ii) ASE would treat the communications and discussions between both parties as confidential, and would not disclose such information externally without the Company’s consent.

28

On November 6, 2015, Mr. Chang sent a letter to Mr. Lin stating that ASE had lawfully acquired 779,000,000 Shares (including those represented by ADSs) upon completion of the Initial ASE Tender Offers and requesting a meeting before November 13, 2015 to discuss specific details of the undertaking proposed by Mr. Lin and plans for potential cooperation.

On November 16, 2015, ASE filed an amendment to its report on Schedule 13D indicating its concerns regarding the Company’s actions in response to ASE’s acquisition of the Shares.

On December 11, 2015, the Company announced a potential transaction with Tsinghua Unigroup Ltd. (“Tsinghua” and the “Tsinghua Transaction”). Pursuant to the Tsinghua Transaction, if approved by the shareholders of the Company, Tsinghua would purchase newly issued Shares by way of private placement at a price of NT$55 per Share. The Tsinghua Transaction would also have required the approval of the Company’s shareholders. On the same day, the Company announced that it planned to hold an extraordinary shareholders’ meeting on January 28, 2016 for shareholders to vote on the Tsinghua Transaction. Upon completion of the Tsinghua Transaction, Tsinghua would have owned 24.9% of the Company’s then-outstanding Shares and have the right to appoint one director to the Board.

On December 14, 2015, ASE submitted a written proposal to the Board proposing to acquire 100% of the remaining outstanding Shares of the Company for NT$55 per Share in cash and 100% of the remaining outstanding ADSs for NT$275 per ADS in cash (the “December 14, 2015 Proposal”). The December 14, 2015 Proposal was subject to execution and delivery of a mutually satisfactory definitive share exchange agreement containing customary terms and conditions, and was contingent on the termination or cancellation of the Tsinghua Transaction. ASE requested a written response from the Board by December 21, 2015 to confirm whether or not the Company was willing to discuss the December 14, 2015 Proposal.

On December 21, 2015, the Company issued a press release stating that it would assess the December 14, 2015 Proposal and that it would discuss the December 14, 2015 Proposal at a meeting of the Board to be held on December 28, 2015.

On December 22, 2015, ASE announced that it planned to commence, on December 29, 2015, tender offers in the ROC and the United States (the “Second ASE Tender Offers”) for up to 770,000,000 Shares, including those represented by ADSs, at a price of NT$55 per Share (and NT$275 per ADS), which represented approximately 24.71% of the issued and outstanding share capital of the Company. In addition, ASE disclosed that if the Second ASE Tender Offers were consummated, subject to either (i) the Company’s shareholders not approving the Tsinghua Transaction at the proposed extraordinary shareholders’ meeting on January 28, 2016 or (ii) the Company terminating the Tsinghua Transaction and cancelling the proposed extraordinary shareholders’ meeting, ASE would seek to cause the Company to enter into a share exchange or other similar business combination with ASE pursuant to which ASE would acquire 100% of the shares of the Company not owned by ASE (a “Proposed Combination”) for the consideration of NT$55 per Share and NT$275 per ADS (subject to adjustment if the Company issued shares or cash dividends prior to the closing of such Proposed Combination). After the Company learned about the Second ASE Tender Offers later that day, the Company contacted Simpson Thacher and Jones Day to act as its U.S. legal advisor and Taiwan legal advisor, respectively. On the same day, the Company issued a press release requesting that ASE cease its plan to commence the Second ASE Tender Offers and provide responses to certain questions as a precondition to any potential discussions on the December 14, 2015 Proposal. The Company also announced on the same day that it planned to postpone the proposed extraordinary general meeting that had been scheduled for January 28, 2016 to consider the Tsinghua Transaction.

29

On December 28, 2015, the Board held a meeting to discuss the December 14, 2015 Proposal and resolved that the Company would agree to initiate the evaluation of the December 14, 2015 Proposal if two conditions were met: (i) ASE immediately ceased its plan to commence the Second ASE Tender Offers and (ii) both parties started the negotiation based on mutually agreed foundations (the “Response”). On the same day, the Company issued a press release announcing the Response and also announced that it planned to postpone the proposed extraordinary shareholders’ meeting that had been scheduled for January 28, 2016 to discuss the Tsinghua Transaction.

On the same day, ASE announced that it intended, as previously announced, to commence the Second ASE Tender Offers on December 29, 2015 and that it believed that the Second ASE Tender Offers did not preclude any discussions with the Company with respect to the December 14, 2015 Proposal.

On December 29, 2015, ASE commenced the Second ASE Tender Offers.

On December 30, 2015, the Company received ASE’s prospectus in respect of the Second ASE Tender Offers. The Company then submitted such prospectus to the Review Committee and the Board to evaluate the Second ASE Tender Offers and engaged Ding Shuo and Diwan & Company Certified Public Accountants (“Diwan”) to separately conduct valuations of the Company and issue fairness opinions. On the same day, the Company announced that it would convene meetings of the Review Committee and the Board to discuss the Second ASE Tender Offers.

On January 7, 2016, the Review Committee and the Board separately held a review committee meeting and a board meeting to discuss and evaluate the Second ASE Tender Offers. Prior to such meetings, Ding Shuo and Diwan delivered fairness opinions, which valued the Shares at NT$56.33 to NT$68.60 per Share and at NT$58.32 to NT$63.44 per Share, respectively. Having considered all the relevant factors, including a review of the fairness opinions provided by Ding Shuo and Diwan, the Review Committee and the Board unanimously concluded that the Second ASE Tender Offers were inadequate and unanimously determined to recommend that holders of the Shares and ADRs consider the Review Committee and the Board’s reservations regarding the Second ASE Tender Offers and further review the relevant risks of the Second ASE Tender Offers before deciding individually whether or not to participate in the Second ASE Tender Offers (the “Company Recommendation to the Second Tender Offers”).

Later on the same day, the Company issued a press release and filed a Solicitation/Recommendation Statement on Schedule 14D-9 (as amended, the “Second Schedule 14D-9”) with the SEC announcing the Company Recommendation to the Second Tender Offers, which it subsequently amended, that shareholders of the Company consider the reservations of the Review Committee and the Board regarding the Second ASE Tender Offers, and further review the relevant risks before deciding individually whether or not to participate in the Second ASE Tender Offers.

On February 4, 2016, ASE extended the Second ASE Tender Offers until March 17, 2016 in order to permit the TFTC further time to review the Proposed Combination. The Second ASE Tender Offers had previously been scheduled to expire on February 16, 2016.

Between February 17, 2016 and March 9, 2016, the Company filed a number of amendments to the Second Schedule 14D-9 clarifying the scope of the Company Recommendation to the Second ASE Tender Offers. During this time, ASE published various advertisements in newspapers in the ROC and made various shareholder communications in connection with the Second ASE Tender Offers.

30

On March 17, 2016, ASE announced that the Second ASE Tender Offers were unsuccessful, as ASE had not received approval from the TFTC for the Proposed Combination between ASE and the Company prior to the expiration of the Second ASE Tender Offers. ASE further stated that it continued to seek to obtain control of the Company, with the purpose of effecting an acquisition of 100% of the Shares and ADSs that ASE did not already own. In addition, ASE stated that it would otherwise continue to seek opportunities for cooperation with the Company and would consider other possibilities, including further acquisitions of Shares. ASE also disclosed that the TFTC was still in the process of reviewing the Proposed Combination. If the TFTC approved the Proposed Combination, ASE expected to continue to seek the support of the shareholders of the Company in order to acquire 100% of the issued and outstanding share capital of the Company not owned by ASE. ASE further explained that, simultaneously with the acquisition of the Company, ASE planned to establish a holding company in Taiwan that would hold 100% of the equity interests of both ASE and the Company such that ASE and the Company would be wholly owned subsidiaries of such holding company, which would maintain all current operations of ASE and the Company in Taiwan.

Between March 24, 2016 and April 7, 2016, ASE acquired by way of market purchases additional Shares and ADSs amounting to an additional 8.29% of the issued and outstanding Shares (including those represented by ADSs) for an aggregate purchase price of NT$13.7 billion.

On April 17, 2016, Mr. Lin and Mr. Chang, together with representatives of ASE and the Company, had a meeting at which they discussed, among other things, the possibility of a combination transaction. During the meeting, Mr. Lin and Mr. Chang discussed whether it would be in the best interests of the two companies and their respective shareholders to explore the possibility of entering into a combination transaction.

Between April 25, 2016 and May 19, 2016, representatives of ASE and the Company, together with their respective legal and financial advisors, held a series of in-person meetings and conference calls to discuss a variety of issues, and explore whether it would be possible to develop the terms of a possible share purchase transaction by ASE of the Company (“Proposed Share Purchase”), including the structure, price, board composition of the new holding company after the Proposed Share Purchase, protection of the Company’s employee rights and the timing of any announcement. ASE furnished the Company with proposed draft transaction documents and presentation materials relating to the Proposed Share Purchase, which contemplated the Company and ASE entering into a share purchase transaction at a price of NT$55.0 per Share and set forth the other terms of such transaction. There was no agreement with respect to the Proposed Share Purchase by the end of these meetings.

On April 28, 2016, upon consideration of subjective and objective factors of the Company and Tsinghua, the Board resolved to terminate the Tsinghua Transaction (the “Tsinghua Transaction Termination”). On the same day, the Company issued a press release announcing the Tsinghua Transaction Termination.

On May 22, 2016, ASE furnished to the Company a draft of the Share Purchase MOU, which contemplated the Company and ASE entering into a share purchase transaction at a price of NT$55.0 per Share and set forth the other terms of such transaction. Prior to the execution thereof, Simpson Thacher and Jones Day, acting as the Company’s legal counsels, exchanged multiple drafts of the Share Purchase MOU with ASE’s legal counsels, Davis Polk and Baker & McKenzie.

On May 23, 2016, the audit committee of the Company held a meeting, at which members of the senior management of the Company participated. At the meeting, the audit committee discussed the background of the Share Purchase, the draft Share Purchase MOU and the engagement of IP International CPAs Firm (“IP International”) to evaluate the fairness of the transaction. Having considered the background of the transaction and all the relevant factors, the audit committee unanimously approved such engagement of IP International. In addition, the audit committee noted during the meeting that they would be acting as the Special Committee of the Company.

31

On May 25, 2016, Mr. Hsu of IP International provided the First IP International Opinion to the Special Committee, concluding that, taking into account various methods they applied in evaluating the share consideration, the consideration of NT$55.0 per Share falls within the range of the reasonable shareholders’ equity value between NT$40.45 and NT$58.98 and, therefore, is fair and reasonable.

On May 26, 2016, the Special Committee held a meeting to discuss the draft Share Purchase MOU, at which members of the senior management of the Company participated. Having considered all the relevant factors, including the First IP International Opinion, the Special Committee unanimously approved the execution of the Share Purchase MOU. Later that same day, the Board held a meeting to discuss the draft Share Purchase MOU, at which members of the senior management of the Company and representatives of the Company’s legal counsel and financial advisor participated. Having considered all the relevant factors, including the decision of the Special Committee, the Board unanimously approved the execution of the Share Purchase MOU and the engagement of J.P. Morgan to evaluate the fairness of this transaction.

On the same date, the board of directors of ASE (the “ASE Board”) held a meeting, at which members of ASE’s senior management participated, to discuss the draft Share Purchase MOU and review the conclusions of ASE’s legal and financial advisors. In connection with the deliberations of the ASE Board, Mr. Ji-Sheng Chiu, CPA of Crowe Horwath, an independent public accounting firm engaged by ASE, delivered to the ASE Board his oral opinion, which was confirmed by delivery of a written opinion dated May 25, 2016, that the cash consideration of NT$55.00 per Share and the exchange ratio pursuant to which ASE Shares would be exchanged for shares in the holding company, were reasonable and fair.

Later on the same day, ASE and the Company issued a joint press release announcing the execution of the Share Purchase MOU and setting a deadline for execution of a definitive Joint Share Exchange Agreement of June 25, 2016. Also on May 26 2016, Mr. Chang sent a letter to Mr. Lin reiterating his support for the proposed combination.

On May 27, 2016, ASE and the Company clarified by their respective press releases that the original per Share consideration of NT$55 per Share included the cash dividend and a returning of capital reserve of NT$3.8 per Share previously declared by the Company, and that the adjusted Final Per Share Consideration should be NT$51.2 per Share.

On June 3, 2016, Baker & McKenzie, ASE’s legal counsel, sent a proposed draft of the Joint Share Exchange Agreement to the Company’s legal counsel, Jones Day, which contemplated, among other things, that ASE would exchange all of ASE’s issued ASE Shares for shares in a newly formed holding company, and all issued Shares would be acquired for NT$55.00 per share in cash and NT$275 per ADS (prior to cash dividend and a returning of capital reserve adjustment).

Between June 3, 2016 and June 24, 2016, representatives of ASE and the Company, together with representatives of each of their legal and financial advisors, held a series of telephonic and in-person meetings to negotiate the terms of the draft Joint Share Exchange Agreement, including the post-closing commitments of the surviving company, the timetable for the transaction and the required regulatory approvals. During this period, ASE’s legal advisors Davis Polk and Baker & McKenzie exchanged multiple drafts of the draft Joint Share Exchange Agreement with the Company’s legal advisors Simpson Thacher and Jones Day.

32

On June 24, 2016, ASE and the Company executed a supplemental Share Purchase MOU, extending the deadline for ASE and the Company to execute a definitive agreement to June 30, 2016.

On June 29, 2016, Mr. Hsu of IP International provided the Second IP International Opinion to the Special Committee, concluding that taking into account various methods they applied in evaluating the share consideration, the consideration of NT$55 per Share (prior to the dividend adjustment) falls within the range of the reasonable shareholders’ equity value between NT$42.80 and NT$60.38 and therefore, is fair and reasonable.

On June 30, 2016, the Special Committee held a meeting to discuss the draft Joint Share Exchange Agreement, at which members of the senior management of the Company participated. Having considered all the relevant factors including the Second IP International Opinion, the Special Committee unanimously determined that the draft Joint Share Exchange Agreement and the transactions contemplated thereby were reasonable and fair to the Company and its shareholders and approved the execution of the Joint Share Exchange Agreement. Later that day, the Board held a meeting to discuss the draft Joint Share Exchange Agreement, at which members of the senior management of the Company and the representatives of the legal and financial counsel of the Company participated. In connection with the deliberations of the Board, J.P. Morgan provided an oral opinion on June 30, 2016 (which was subsequently confirmed by the delivery of a written opinion on the same date) to the Board, stating that the consideration of NT$51.2 per Share and NT$256 per ADS were fair and reasonable from a financial point of view. Having carefully considered all relevant factors, the Board approved the execution, delivery and performance by the Company of the Joint Share Exchange Agreement.

On June 30, 2016, the ASE audit committee unanimously determined that the draft Joint Share Exchange Agreement and the transactions contemplated thereby were advisable, fair to and in the best interests of ASE and its shareholders and approved the draft Joint Share Exchange Agreement and the other transactions contemplated therein. Later that same day, the ASE Board met to discuss the draft Joint Share Exchange Agreement, in which members of ASE senior management participated. Prior to the meeting, members of the ASE Board had been provided with a set of meeting materials, including the draft Joint Share Exchange Agreement and certain financial analyses. In connection with the deliberations of the ASE Board, an independent expert engaged by ASE, Mr. Ji-Sheng Chiu, CPA, delivered to the ASE Board his oral opinion, which was confirmed by delivery of a written opinion dated June 29, 2016, that the consideration in the draft Joint Share Exchange Agreement of NT$55.00 per Share and NT$275 per ADS (prior to cash dividend and a returning of capital reserve adjustment) and the exchange ratio pursuant to which ASE Shares would be exchanged for shares in the holding company, were reasonable and fair.

On June 30, 2016, ASE and the Company issued a joint press release announcing the execution of the Joint Share Exchange Agreement.

Reasons for the Share Purchase, Review Conclusion of the Special Committee and Recommendation of Our Board

Based on the foregoing considerations, the Board has concluded that it is more beneficial to the Company to undertake the Share Purchase and become a private company as a result of the Share Purchase than to remain a public company. In evaluating the Share Purchase, including the terms and conditions of the Joint Share Exchange Agreement, our Board consulted with the management team of the Company and the legal and financial advisors and acted upon the unanimous determination of the Special Committee.

33

At a meeting on June 30, 2016, the Special Committee, taking into account the conclusion of Mr. Hsu of IP International, an independent expert retained by the Special Committee, unanimously determined that the terms and conditions of the Joint Share Exchange Agreement are reasonable and fair to the Company and submitted its review minutes and conclusions to the Board for consideration.

At a meeting on June 30, 2016, having carefully considered all relevant factors, including the unanimous determination of the Special Committee, our Board adopted resolutions that:

| • |  | determined that it is fair to and in the best interests of the Company, and declared it advisable, that the Company should approve and, as the case may be, enter into the Joint Share Exchange Agreement and the Share Purchase;

| • |  | approved the execution, delivery and performance by the Company of the Joint Share Exchange Agreement and the completion of the transactions contemplated thereby, including the Share Purchase; and

| • |  | directed that the authorization and approval of the Joint Share Exchange Agreement be submitted to a vote at an extraordinary general meeting of the shareholders of the Company and recommended that the shareholders of the Company authorize and approve by way of a special resolution the Joint Share Exchange Agreement and the Share Purchase.

In the course of reaching their respective determinations, the Special Committee and/or our Board considered the following substantive factors and potential benefits of the Share Purchase, each of which the Special Committee and our Board believed supported their respective decisions, but which are not listed in any relative order of importance:

| • |  | our Board’s knowledge of our business, financial condition, results of operations, prospects and competitive position and its belief that the Share Purchase is more favorable to our shareholders than any other alternative reasonably available to the Company and our shareholders;

| • |  | estimated forecasts of our future financial performance prepared by our management, together with our management’s view of our financial condition, results of operations, business, prospects and competitive position;

| • |  | the belief of the Special Committee that the terms of the Joint Share Exchange Agreement, including the parties’ representations, warranties and covenants, and the conditions to their respective obligations, are reasonable;

| • |  | the all-cash Share Purchase consideration, which will allow our shareholders and ADS holders to promptly realize liquidity for their investment and provide them with certainty of the value for their Shares or ADSs;

| • |  | the current and historical market prices of our Shares and ADSs, including the fact that the Original Per Share Consideration and the Original Per ADS Consideration represent a premium of 8.9% and 12.3%, respectively, over the closing price of NT$50.5 per Share and $7.52 per ADS, respectively, on the Last Trading Day, and a premium of 17.4% and 10.3%, respectively, over the Company’s one-month and three-month volume-weighted average price of NT$46.86 and NT$49.85, respectively, as quoted by the Taiwan Stock Exchange on the Last Trading Day, and a premium of 19.7% and 11.6%, respectively, over the Company’s one-month and three-month volume-weighted average price of $7.06 and $7.57, respectively, as quoted by NASDAQ on the Last Trading Day;

34

| • |  | the possibility that it could take a considerable period of time before the trading price of the Shares and the ADSs would reach and sustain at least the Share Purchase consideration of the Final Per Share Consideration or the Final Per ADS Consideration, as adjusted for present value;

| • |  | the fact that the Company can independently conduct its business after the consummation of the Share Purchase;

| • |  | the ability of the Company to terminate the Joint Share Exchange Agreement upon acceptance of a Superior Proposal (as defined in the section entitled “The Joint Share Exchange Agreement—Pre-Closing Covenants of the Company—Superior Proposals”), subject to compliance with the terms and conditions of the Joint Share Exchange Agreement;

| • |  | the likelihood that the Share Purchase would be completed based on, among other things (not in any relative order of importance):

| • |  | the absence of financing condition in the Joint Share Exchange Agreement; and

| • |  | the likelihood and anticipated timing of completing the Share Purchase in light of the limited scope of the conditions to completion;

| • |  | our ability, under certain circumstances, to change, withhold, withdraw, qualify or modify our recommendation that our shareholders vote to adopt the Joint Share Exchange Agreement;

| • |  | the IP International Opinions rendered to the Special Committee on May 25, 2016 and June 29, 2016, respectively, as to the fairness, from a financial point of view, of the Original Per Share Consideration and the Original Per ADS Consideration;

| • |  | the financial analysis reviewed and discussed with the Board by representatives of J.P. Morgan, as well as the opinion of J.P. Morgan rendered to the Board on June 30, 2016 as to the fairness, from a financial point of view, of the Final Per Share Consideration and the Final Per ADS Consideration to be paid to holders of Shares and ADSs in the Share Purchase, as of June 30, 2016, based upon and subject to the procedures followed, assumptions made, qualifications and limitations on the review undertaken and other matters considered by J.P. Morgan in preparing its opinion. Please see “—Opinion of the Board’s Financial Advisor” beginning on page 44 for additional information; and

| • |  | since the announcement of the proposed transaction on May 26, 2016 and prior to the entry into the Joint Share Exchange Agreement, no party other than ASE had contacted the Company or the Special Committee expressing an interest in exploring an alternative transaction with the Company.

In addition, the Special Committee and our Board believed that sufficient procedural safeguards were and are present to ensure that the Share Purchase is procedurally fair to our shareholders and ADS holders and to permit the Special Committee and our Board to represent effectively the interests of such shareholders and ADS holders. These procedural safeguards, which are not listed in any relative order of importance, are discussed below:

| • |  | the consideration of the Joint Share Exchange Agreement was conducted under the control and supervision of the Special Committee, which consists solely of independent directors, each of whom is an outside, non-employee director, and no limitations were placed on the Special Committee’s authority;

35

| • |  | in considering the transaction with ASE, the Special Committee had independent judgment free from the influence of any interested parties;

| • |  | all of the directors serving on the Special Committee during the entire process were and are independent directors and free from any affiliation with ASE. In addition, none of such directors is or ever was an employee of the Company or any of its subsidiaries or affiliates, and none of such directors has any financial interest in the Share Purchase that is different from that of the shareholders and ADS holders other than the members’ indemnification and liability insurance rights under the Joint Share Exchange Agreement;

| • |  | the Special Committee was assisted in its evaluation of the Share Purchase by IP International’s fairness opinions;

| • |  | the Special Committee and our Board were empowered to consider, attend to and take any and all actions in connection with the proposed Joint Share Exchange Agreement and the transactions contemplated thereby from the date the committee was established, and no evaluation, negotiation, or response regarding the transaction or any documentation in connection therewith from that date forward was considered by our Board for approval unless the Special Committee had recommended such action to our Board;

| • |  | the terms and conditions of the Joint Share Exchange Agreement were the product of extensive negotiations between the authorized representatives of the Company and its advisors, under the supervision of the Special Committee, on the one hand, and ASE and its advisors, on the other hand;

| • |  | the Special Committee was empowered to exercise any power or authority that the Special Committee determined was necessary or advisable in carrying out and fulfilling its duties and responsibilities;

| • |  | the recognition by the Special Committee and our Board that they had no obligation to recommend the approval of the Share Purchase proposal from ASE or any other transaction;

| • |  | the recognition by the Special Committee and our Board that, under the terms of the Joint Share Exchange Agreement, they have the ability to consider any acquisition proposal reasonably likely to lead to a Superior Proposal until the date our shareholders vote upon and approve the Joint Share Exchange Agreement;

| • |  | the ability of the Company to terminate the Joint Share Exchange Agreement upon acceptance of a Superior Proposal, subject to compliance with the terms and conditions of the Joint Share Exchange Agreement; and

| • |  | the availability of appraisal rights to the shareholders who comply with all of the required procedures under the ROC M&A Act for exercising dissenters’ and appraisal rights, which allow such shareholders to seek appraisal of the fair value of their Shares as determined by the court in Taiwan.

36

The Special Committee and/or the Board also considered a variety of potentially negative factors discussed below concerning the Joint Share Exchange Agreement and the Share Purchase, which are not listed in any relative order of importance:

| • |  | the fact that the shareholders and ADS holders will have no ongoing equity participation in the Company following the Share Purchase, and that they will cease to participate in our future earnings or growth, if any, or to benefit from increases, if any, in the value of the Shares, and will not participate in any potential future sale of the Company to a third party or any potential recapitalization of the Company which could include a dividend to shareholders;

| • |  | the restrictions on the conduct of the Company’s business prior to the completion of the Share Purchase, which may delay or prevent the Company from undertaking business opportunities that may arise or any other action it would otherwise take with respect to the operations of the Company pending completion of the Share Purchase;

| • |  | the risks and costs to the Company if the Share Purchase does not close, including the diversion of management and employee attention, potential employee attrition, and the potential disruptive effect on business and customer relationships;

| • |  | that the Company will be required to, in the event of the Company’s material breach of certain provisions of the Joint Share Exchange Agreement, pay liquidated damages to ASE in the amount of NT$8.5 billion, and reimburse ASE’s expenses, in connection with the termination of the Joint Share Exchange Agreement;

| • |  | the fact that the Company’s remedy in the event of breach of the Joint Share Exchange Agreement by ASE is limited, under certain circumstances, to receipt of liquidated damages in the amount of NT$8.5 billion and reimbursement of the Company’s expenses, and under certain circumstances the Company may not be entitled to a liquidated damage or expenses at all;

| • |  | the terms of ASE’s participation in the Share Purchase and the fact that ASE may have interests in the transaction that are different from, or in addition to, those of our shareholders and ADS holders (please see “—Interests of Certain Persons in the Share Purchase” beginning on page 67 for additional information);

| • |  | the risk that the parties may fail to obtain the required approval from the shareholders of the Company or the shareholders of ASE or that completion may be unduly delayed for reasons beyond the control of the Company and/or ASE, including the potential length of the regulatory review process and the risk that applicable antitrust and competition authorities may prohibit or enjoin the Share Purchase or otherwise impose unanticipated conditions on the Company and/or ASE, in order to obtain clearance for the Share Purchase;

| • |  | the possibility that the Share Purchase might not be completed and the negative impact of a public announcement of the Share Purchase on our sales and operating results and our ability to attract and retain key management, marketing and technical personnel;

| • |  | the taxability of an all-cash transaction to our shareholders and ADS holders who are U.S. Holders (as defined under “Material U.S. Federal Income Tax Considerations”) for U.S. federal income tax purposes; and

| • |  | the possibility that ASE and/or HoldCo may be unable or unwilling to complete the Share Purchase, including if ASE and/or HoldCo is unable to obtain sufficient financing to complete the Share Purchase despite their compliance with their financing obligations set forth in the Joint Share Exchange Agreement or if ASE chooses not to complete despite the availability of financing.

37

The foregoing discussion of information and factors considered by the Special Committee and/or our Board is not intended to be exhaustive, but includes a number of the factors considered by the Special Committee and/or our Board. In view of the wide variety of factors considered by the Special Committee and/or our Board, neither the Special Committee nor our Board found it practicable to quantify or otherwise assign relative weights to the foregoing factors in reaching its conclusions. In addition, individual members of the Special Committee and/or our Board may have given different weights to different factors and may have viewed some factors more positively or negatively than others. The Special Committee determined that the terms and conditions of the Joint Share Exchange Agreement are fair and reasonable, and our Board approved the Joint Share Exchange Agreement based upon the totality of the information presented to and considered by it.

Neither the Special Committee nor our Board considered the liquidation value of the Company’s assets because each considers the Company to be a viable-going concern business where value is derived from cash flows generated from its continuing operations. In addition, the Special Committee and the Board believe that the value of the Company’s assets that might be realized in liquidation would be significantly less than its going-concern value. Each of the Special Committee and the Board believes that the analyses and additional factors it reviewed provided an indication of our going-concern value. Each of the Special Committee and the Board also considered the historical market prices of our ADSs as described under the caption “Market Price of the Company’s ADSs, Dividends and Other Matters—Market Price of the ADSs” beginning on page 72. Neither the Special Committee nor our Board considered the Company’s net book value, which is defined as total assets minus total liabilities, attributable to the shareholders of the Company, as a factor. The Special Committee and the Board believe that net book value is not a material indicator of the value of the Company as a going concern. The Company’s net book value per Share as of December 31, 2015 was NT$22.31 (or NT$22.31 based on the weighted average number of outstanding Shares during 2015). Net book value does not take into account the future prospects of the Company, market conditions, trends in the industry related to the development, manufacturing and marketing of mobile communications devices and accessories or the business risks inherent in competing with larger companies in that industry.

In reaching its determination that the Joint Share Exchange Agreement and the transactions contemplated thereby, including the Share Purchase, are in the best interests of the Company and our shareholders and ADS holders and its decision to approve the Joint Share Exchange Agreement and recommend the approval of the Joint Share Exchange Agreement by our shareholders, our Board considered the analysis and conclusions of the Special Committee and the factors examined by the Special Committee as described above in this section and adopted such analysis and conclusions. For the foregoing reasons, our Board believes that the Joint Share Exchange Agreement and the transactions contemplated thereby are substantively and procedurally fair to our shareholders and ADS holders.

ASE’s Purposes of and Reasons for the Share Purchase

Under a possible interpretation of the SEC rules governing “going private” transactions, ASE may be deemed to be engaged in a “going private” transaction and, therefore, required to express its reasons for the Share Purchase to the Company’s unaffiliated security holders, as defined in Rule 13e-3 of the Exchange Act. ASE is making the statements included in this section solely for the purpose of complying with the requirements of Rule 13e-3 and related rules under the Exchange Act. For ASE, the purpose of the Share Purchase is to enable HoldCo to acquire 100% control of the Company, in a transaction in which all shareholders of the Company will be cashed out in exchange for the Final Per Share Consideration and Final Per ADS Consideration, as applicable, so that HoldCo will bear the rewards and risks of the sole ownership of the Company, including any increases in value of the Company as a result of improvements to the Company’s operations or acquisitions of other businesses.

38

ASE believes that in light of the increase in competition and the consolidation trends in the global semiconductor industry, an investment in the Company would present attractive opportunities. ASE further believes that, as a privately held company, the Company will have greater flexibility to focus on addressing the challenges to the Company’s long-term profitability without the constraints caused by the public equity market’s valuation of the Company and emphasis on short-term period-to-period performance. Further, as a privately held company, the Company will be relieved of many of the expenses, burdens and constraints imposed on companies that are subject to the public reporting requirements under the U.S. federal securities laws, including the Exchange Act and the Sarbanes-Oxley Act of 2002.

ASE decided to undertake the “going private” transaction at this time because it wants to take advantage of the benefits of the Company being a privately held company as described above.

Position of ASE as to Fairness of the Share Purchase

Although ASE has informed us that it does not believe at this time that it is an affiliate of the Company, pursuant to SEC rules ASE may be deemed to be an affiliate of the Company, and if so, pursuant to SEC rules, the Share Purchase may constitute a “going-private” transaction as defined in Rule 13e-3 under the Exchange Act. Under Rule 13e-3 under the Exchange Act, ASE is required to express its beliefs as to the fairness of the Share Purchase to the Company’s unaffiliated security holders, as defined in Rule 13e-3. ASE is making the statements included in this section solely for the purpose of complying with the requirements of Rule 13e-3 and related rules under the Exchange Act. The views of ASE as to the fairness of the Share Purchase are not intended to be and should not be construed as a recommendation to any shareholder of the Company as to how to vote on the proposal to authorize and approve the Joint Share Exchange Agreement and the transactions contemplated by the Joint Share Exchange Agreement, including the Share Purchase.

ASE believes that the interests of the Company’s unaffiliated security holders were represented by the Board and Special Committee, which negotiated the terms and conditions of the Joint Share Exchange Agreement with the assistance of its legal and financial advisors. ASE did not participate in the deliberations of the Board and Special Committee regarding, and did not receive any advice from the Board’s or Special Committee’s advisors as to, the fairness of the Share Purchase to the Company’s unaffiliated security holders. ASE attempted to negotiate a transaction that would be most favorable to ASE and its shareholder, and not to the Company’s unaffiliated security holders and, accordingly, did not negotiate the Joint Share Exchange Agreement with a goal of obtaining terms that were substantively and procedurally fair to such holders. ASE agreed with the analyses and determinations as to the fairness reached by the Special Committee, based upon the reasonableness of the analyses and determinations, and their respective knowledge. ASE expressly adopted the analysis and conclusions reached by the Company that the Share Purchase is fair to the Company’s unaffiliated security holders.

Based on their knowledge and analysis of the Company, as well as discussions with the Company’s management regarding the Company and its business, and the factors considered by, and the conclusions of, the Board and the Special Committee discussed in “Reasons for the Share Purchase, Review Conclusion of the Special Committee and Recommendation of Our Board” beginning on page 33, ASE believes that the Share Purchase is both substantively and procedurally fair to the Company’s unaffiliated security holders based upon the following factors, which are not listed in any relative order of importance:

| • |  | in considering the Share Purchase, the Special Committee, which consists solely of independent directors, acted solely to represent the interests of the Company and the Company’s shareholders, unanimously approved the Share Purchase, and had independent control of the negotiations with ASE on behalf of the Company and the shareholders of the Company;

39

| • |  | despite holding a 33.29% equity interest in the Company, ASE did not, and currently does not, have any appointee on the Board. All of the directors serving on the Board during the entire process were and are free from any affiliation with ASE. In addition, none of the directors and executive officers involved in the process is or ever was an employee of ASE or any of its subsidiaries or affiliates and none of such directors or executive officers has any financial interest in the Share Purchase that is different from that of the unaffiliated security holders other than the director’s receipt of board compensation and executive officers’ salaries in the ordinary course;

| • |  | the Special Committee retained and was advised by legal and independent experts experienced in assisting committees such as the Special Committee in similar transactions;

| • |  | neither the Special Committee nor the Board had any obligation to recommend authorization or approval of the Joint Share Exchange Agreement and the transactions contemplated thereby, including the Share Purchase, or any other transaction;

| • |  | the fact that the Special Committee received from its independent expert, Mr. Hsu of IP International, two opinions dated May 25, 2016 and June 29, 2016, and the Board received from its financial advisor, J.P. Morgan an opinion, dated June 30, 2016, in each case as to the fairness, from a financial point of view and as of their respective dates, of the consideration to be received by holders of the Shares in the Share Purchase;

| • |  | the First Crowe Horwath Opinion, dated May 25, 2016, and the Second Crowe Horwath Opinion, dated June 29, 2016, to the ASE Board as to the fairness, from a financial point of view and as of the respective date of each opinion, to ASE, of the cash consideration to be paid by HoldCo to the Company shareholders and the Exchange Ratio pursuant to which ASE shareholders will exchange their shares for HoldCo Shares pursuant to the Joint Share Exchange Agreement;

| • |  | the current and historical market prices of the Shares, including the fact that the Original Per Share Consideration represents a 9.0% premium to the closing price of Shares on the TWSE on the Last Trading Date, a 14% premium to the average closing price for the one week prior to the announcement of the Share Purchase MOU, and an 18% premium to the average closing price for the four weeks prior to the announcement of the Share Purchase MOU;

| • |  | the current and historical market prices of ADSs, including the fact that the Cash Consideration of NT$275 in cash per ADS represents a 13% premium to the closing price of ADSs on NASDAQ on the Last Trading Date, a 19% premium to the average closing price for the one week prior to the announcement of the Share Purchase MOU, and a 21% premium to the average closing price for the four weeks prior to the announcement of the Share Purchase MOU;

40

| • |  | the consideration payable to the shareholders of the Company in the Share Purchase will be paid in cash, which provides the shareholders of the Company certainty of value and immediate liquidity without exposure to longer-term business risks;

| • |  | the Share Purchase provides shareholders the opportunity to liquidate their positions without a discount to reflect market conditions;

| • |  | the Share Purchase provides the opportunity for the shareholders of the Company to sell their shares without incurring brokerage and other costs typically associated with market sales;

| • |  | the fact that, under the terms of the Joint Share Exchange Agreement, the Company has the ability to consider any proposal regarding an alternative transaction that is a Superior Proposal subject to compliance with the terms and conditions of the Joint Share Exchange Agreement;

| • |  | the ability of the Board, under certain circumstances, to choose to terminate the Joint Share Exchange Agreement in connection with a Superior Proposal, subject to compliance with the terms and conditions of the Joint Share Exchange Agreement;

| • |  | the right of the Company to choose to accept a Superior Proposal from a third party the conditions of which, in the respective opinions of the Special Committee and the Board, are more favorable than those of the Share Purchase; and

| • |  | the availability of dissenter rights to the shareholders of the Company who comply with all of the required procedures under the ROC M&A Act for exercising dissenter rights, which allow such holders to receive the fair value of their Shares.

ASE also considered the following factors, each of which they considered to be negative, in their deliberations concerning the fairness of the terms of the Share Purchase:

| • |  | following the successful completion of the Share Purchase, shareholders of the Company would cease to participate in the future earnings or growth, if any, of the Company or benefit from increases, if any, in the value of their holdings of the Company;

| • |  | as to the cash consideration paid to the shareholders of the Company in the Share Purchase, the financial interests of ASE are different from the financial interests of the shareholders of the Company;

| • |  | the approval of a majority of the shareholders of the Company not affiliated with ASE will not be required to approve the Share Purchase; and

| • |  | the receipt of cash proceeds by U.S. holders in the Share Purchase is taxable to certain shareholders.

In reaching its conclusion as to fairness, ASE did not consider the Company’s total enterprise value, or estimate the value of any of the Company’s assets, and ASE did not otherwise consider the liquidation value of the Company’s assets because ASE considers the Company to be a viable going concern. In addition, the liquidation of the Company’s assets was not considered to be a viable course of action based on ASE’s desire for the Company to continue to conduct its business. Therefore, no appraisal of liquidation value was sought for purposes of valuing the Shares and ADSs, and ASE believes that the liquidation value of the Company is irrelevant to a determination as to whether the Share Purchase is fair to the Company’s unaffiliated security holders.

41

In reaching its conclusion as to fairness, ASE considered the market prices for the Shares, including the average closing prices for the Shares over the 60, 90 and 180-business day periods prior to the announcement of the execution of the Share Purchase MOU and the execution of the Joint Share Exchange Agreement.

ASE did not consider net book value, which is an accounting concept, as a factor because ASE believes that net book value is not a material indicator of the value of the Company as a going concern, but rather is indicative of historical costs. Based on the Company’s financial statements as of and for the six months ended June 30, 2016, the Company’s net book value per share as of September 30, 2016, calculated by dividing total shareholders’ equity by the number of the Shares (including those represented by ADSs) outstanding, was NT$20.35 (US$0.65).

ASE is not aware of any firm offers made for the Company during the past two years and, in any event ASE has no current intention of selling the Shares and ADSs it owns, and therefore did not consider any such offers in reaching its conclusion as to fairness.

ASE’s consideration of the factors described above reflects its assessment of the fairness of the cash consideration offered to the Company’s unaffiliated security holders in relation to the going-concern value of the Company on a stand-alone basis.

Certain Financial Projections

The Company’s management does not, as a matter of course, make available to the public future financial projections. However, in connection with their financial analysis of the Share Purchase, our management provided certain financial projections for the fiscal year ending December 31, 2016 through the fiscal year ending December 31, 2025 to J.P. Morgan. Please see “—Background of the Share Purchase; Past Contacts; Negotiations” beginning on page 26 for additional information. These financial projections, which were based on our management’s projection of our future financial performance as of the date provided, were prepared by the Company’s management for internal use and for use by the Special Committee and J.P. Morgan in their financial analyses, and were not prepared with a view toward public disclosure or compliance with published guidelines of the SEC regarding forward-looking information or the guidelines established by the American Institute of Certified Public Accountants for preparation and presentation of financial forecasts or U.S. generally accepted accounting principles (“U.S. GAAP”).

The financial projections are not a guarantee of performance and actual results may differ materially from those anticipated in the financial projections as a result of various factors including those set forth under “Item 3.D. Risk Factors” of the Company’s Annual Report on Form 20-F for the year ended December 31, 2015. They involve significant risks, uncertainties and assumptions. In compiling the projections, the Company’s management took into account historical performance, combined with estimates regarding revenues, operating income and operating expenses. Although the projections are presented with numerical specificity, they were based on numerous assumptions and estimates as to future events made by our management that our management believed were reasonable at the time the projections were prepared. However, this information is not fact and should not be relied upon as being necessarily indicative of actual future results and since our projections rely on the use of estimates and assumptions, actual results could differ from what we expect. This is especially true with some financial projections the accounting policies of which require higher degrees of judgment than others in their application. Significant accounting estimates include revenue recognition, allowance for doubtful accounts, income taxes, fair value and impairment of goodwill and intangible assets, business acquisition and share-based compensation. In addition, factors such as industry performance, the market for our existing and new products, the competitive environment, expectations regarding future acquisitions or any other transaction and general business, economic, regulatory, market and financial conditions, all of which are difficult to predict and beyond the control of our management, may cause actual future results to differ materially from the results forecasted in these financial projections. In addition, the projections do not take into account any circumstances or events occurring after the date that they were prepared. For instance, the projections do not give effect to the Share Purchase or any changes to our operations or strategy that may be implemented after the time the projections were prepared. There can be no assurance that the projections will be realized or that actual results will not be significantly different from those contained in the projections.

The prospective financial information included in this proxy statement has been prepared by, and is the responsibility of, the Company’s management. The Company and its management believe that the prospective financial information has been prepared on a reasonable basis, reflecting the best estimates and judgments, and represent, to the best of management’s knowledge and opinion, the Company’s expected course of action. However, because this information is highly subjective, it should not be relied on as necessarily indicative of future results. PricewaterhouseCoopers, Taiwan (“PwC Taiwan”) has neither examined, compiled, nor performed any procedures with respect to the prospective financial information contained herein and, accordingly, PwC Taiwan does not express an opinion or any other form of assurance on such information or its achievability. PwC Taiwan assumes no responsibility for and denies any association with the prospective financial information. PwC Taiwan’s report, incorporated herein by reference to the Company’s annual report on Form 20-F filed with the SEC on April 25, 2016, refers exclusively to the Company’s historical financial statements. It does not extend to the prospective financial information and should not be read to do so. The financial projections included in this proxy statement are included solely to give shareholders access to certain information that was made available to ASE and are not included for the purpose of influencing any shareholder to make any investment decision with respect to the Share Purchase, including whether or not to seek appraisal for his or her Shares.

The inclusion of the projections should not be regarded as an indication that the Company, ASE, the Special Committee, any of their respective financial advisors or anyone who received the projections then considered, or now considers, them a reliable prediction of future events, and the projections should not be relied upon as such. None of the Company, ASE, the Special Committee or any of their financial advisors or any of their affiliates assumes any responsibility for the validity, reasonableness, accuracy or completeness of the projections. None of the Company, ASE, the Special Committee or any of their financial advisors or any of their affiliates intends to, and each of them disclaims any obligation to, update, revise or correct the projections if they are or become inaccurate (even in the short term).

The inclusion of the projections in this proxy statement should not be deemed an admission or representation by the Company, ASE or the Special Committee that they are viewed by the Company, ASE or the Special Committee as material information of the Company, and in fact the Company, ASE and the Special Committee view the projections as non-material because of the inherent risks and uncertainties associated with such long-range forecasts. The projections should be evaluated, if at all, in conjunction with the historical financial statements and other information regarding the Company contained in the Company’s public filings with the SEC. In light of the foregoing factors and the uncertainties inherent in the projections, shareholders are cautioned not to place undue, if any, reliance on the projections included in this proxy statement.

Opinion of the Board’s Financial Advisor

Pursuant to an engagement letter dated May 26, 2016, the Board retained J.P. Morgan as its financial advisor to deliver a fairness opinion in connection with the Joint Share Exchange Agreement. J.P. Morgan is an internationally recognized financial services firm that, among other things, is regularly engaged in the investment banking business, including the valuation of businesses and securities in connection with mergers and acquisitions, underwritings and private placements of securities, and other investment banking services.

At the meeting of the Board on June 30, 2016, J.P. Morgan rendered its oral opinion to the Board that, as of such date and based upon and subject to the factors, assumptions and limitations set forth in its opinion, the consideration to be paid to the holders of the Shares, including the Shares represented by ADSs in the proposed Share Purchase, was fair, from a financial point of view, to such holders. J.P. Morgan has confirmed its oral opinion rendered on June 30, 2016 by delivering its written opinion to the Board, dated as of the same date, that, as of such date, the consideration to be paid to the holders of the Shares, including the Shares represented by ADSs in the proposed Share Purchase, was fair, from a financial point of view, to such holders. No limitations were imposed by the Board upon J.P. Morgan with respect to the investigations made or procedures followed by it in rendering its opinions.

44

The full text of the written opinion of J.P. Morgan dated June 30, 2016, which sets forth the procedures followed, assumptions made, matters considered and qualifications and limitations on the review undertaken, is attached as Annex B to this proxy statement and is incorporated herein by reference. The summary of the opinion of J.P. Morgan set forth in this proxy statement is qualified in its entirety by reference to the full text of such opinion. The shareholders of the Company are urged to read the opinion in its entirety. J.P. Morgan’s written opinion is addressed to the Board (in its capacity as such), is directed only to the consideration to be paid to the holders of the Shares, including the Shares represented by ADSs in the proposed Share Purchase and does not constitute a recommendation to any shareholder of the Company, or holder of ADSs, as to how such shareholder or holder of ADSs should vote with respect to the Share Purchase or any other matter.

In connection with preparing its opinion, J.P. Morgan, among other things:

| • |  | reviewed a draft of the Joint Share Exchange Agreement dated June 30, 2016;

| • |  | reviewed certain publicly available business and financial information concerning the Company and the industries in which it operates;

| • |  | compared the proposed financial terms of the Share Purchase with the publicly available financial terms of certain transactions involving companies that J.P. Morgan deemed relevant, and the consideration paid for such companies;

| • |  | compared the financial and operating performance of the Company with publicly available information concerning certain other companies that J.P. Morgan deemed relevant and reviewed the current and historical market prices of the Shares and certain publicly traded securities of such other companies;

| • |  | reviewed certain internal financial analyses and forecasts prepared by or at the direction of the management of the Company relating to its business; and

| • |  | performed such other financial studies and analyses and considered such other information as J.P. Morgan deemed appropriate for the purposes of its opinion.

J.P. Morgan also held discussions with certain members of the management of the Company with respect to certain aspects of the Share Purchase, the past and current business operations of the Company, the financial condition and future prospects and operations of the Company, and certain other matters J.P. Morgan believed necessary or appropriate to its inquiry.

In giving its opinion, J.P. Morgan relied upon and assumed the accuracy and completeness of all information that was publicly available or was furnished to or discussed with J.P. Morgan by the Company or otherwise reviewed by or for J.P. Morgan. J.P. Morgan did not independently verify (nor did J.P. Morgan assume responsibility or liability for independently verifying) any such information or its accuracy or completeness. J.P. Morgan did not conduct and was not provided with any valuation or appraisal of any assets or liabilities, nor did J.P. Morgan evaluate the solvency of the Company under any applicable laws relating to bankruptcy, insolvency or similar matters. In relying on financial analyses and forecasts provided to it or derived therefrom, J.P. Morgan assumed that they had been reasonably prepared based on assumptions reflecting the best then-available estimates and judgments by management as to the expected future results of operations and financial condition of the Company to which such analyses or forecasts relate. J.P. Morgan expressed no view as to such analyses or forecasts or the assumptions on which they were based. J.P. Morgan also assumed that the Share Purchase and the other transactions contemplated by the Joint Share Exchange Agreement will be consummated as described in the draft Joint Share Exchange Agreement, and that the definitive Joint Share Exchange Agreement will not differ in any material respects from the draft furnished to J.P. Morgan. J.P. Morgan also assumed that the representations and warranties made by the Company and ASE in the Joint Share Exchange Agreement and the related agreements were and will be true and correct in all respects material to its analysis. J.P. Morgan did not act as legal, regulatory or tax experts and relied on the assessments made by advisors to the Company with respect to such issues. J.P. Morgan further assumed that all material governmental, regulatory or other consents and approvals necessary for the consummation of the Share Purchase will be obtained without any adverse effect on the Company or on the contemplated benefits of the Share Purchase.

45

The financial projections furnished to J.P. Morgan for the Company and used in connection with J.P. Morgan’s analysis of the Share Purchase were prepared by or at the direction of the management of the Company and approved for use by J.P. Morgan by the Company. The Company informed J.P. Morgan that it does not publicly disclose internal management projections of the type provided to J.P. Morgan in connection with J.P. Morgan’s analysis of the Share Purchase, and such projections were not prepared with a view toward public disclosure. These projections were based on numerous variables and assumptions that are inherently uncertain and may be beyond the control of management, including, without limitation, factors related to general economic and competitive conditions and prevailing interest rates. Accordingly, actual results could vary significantly from those set forth in such projections.

J.P. Morgan’s opinion is necessarily based on economic, market and other conditions as in effect on, and the information made available to J.P. Morgan as of June 30, 2016 (being the date of such opinion). It should be understood that subsequent developments may affect J.P. Morgan’s opinion, and J.P. Morgan does not have any obligation to update, revise or reaffirm such opinion. J.P. Morgan’s opinion is limited to the fairness, from a financial point of view, of the consideration to be paid to the holders of the Shares, including the Shares represented by ADSs in the proposed Share Purchase, and J.P. Morgan expressed no opinion as to the fairness of any consideration paid in connection with the Share Purchase to the holders of any other class of securities, creditors or other constituencies of the Company or as to the underlying decision by the Company to engage in the Share Purchase. Furthermore, J.P. Morgan expressed no opinion with respect to the amount or nature of any compensation to any officers, directors or employees of any party to the Share Purchase, or any class of such persons relative to the consideration to be paid to the holders of the Shares, including the Shares represented by ADSs in the Share Purchase or with respect to the fairness of any such compensation. J.P. Morgan expressed no opinion with respect to the value of the common shares of Holdco when issued or the prices at which such common shares will trade at any time.

J.P. Morgan noted that, prior to June 30, 2016, the date on which J.P. Morgan delivered the written opinion to the Board, it was not authorized to and did not solicit any expressions of interest from any other parties with respect to the sale of all or any part of the Company or any other alternative transaction in connection with the Share Purchase.

In accordance with customary investment banking practice, J.P. Morgan employed generally accepted valuation methodologies in reaching its opinion. The following is a summary of the material financial analyses utilized by J.P. Morgan in connection with providing its opinion. J.P. Morgan has consented to the inclusion and disclosure of its financial analyses in this proxy statement. Some of the summaries of the financial analyses include information presented in tabular format. The tables are not intended to stand alone. In order to fully understand the financial analyses used by J.P. Morgan, the tables must be read together with the full text of each summary. Considering the data in the tables without considering the full narrative description of the financial analyses, including the methodologies and assumptions underlying the analyses, could create a misleading or incomplete view of J.P. Morgan’s financial analyses. All values in the Company’s historical financial statements and management projections used in connection with J.P. Morgan’s analyses were prepared by the management and presented in accordance with Taiwan IFRS.

46

All values in the sections “Discounted Cash Flow Analysis” and “Public Trading Multiples Analysis” below are presented on an equity value per common share basis. In arriving at equity value per common share for the Company, the analysis started with the determination of enterprise value, or “EV, ” for the Company. Enterprise value was then adjusted by subtracting total debt outstanding as of March 31, 2016 (excluding the Company’s US$400 million convertible bonds from total debt if the implied per share price under respective methodologies is higher than the estimated conversion price of NT$45.75 per share), subtracting total unconsolidated investments as of March 31, 2016 (including the total available-for-sale financial assets and long-term investments under equity method), and adding pro-forma cash and cash equivalents (cash and cash equivalents as of March 31, 2016 adjusted by subtracting dividends payable of NT$11.8 billion for the dividends announced on May 16, 2016) to arrive at an equity value for the Company. Equity value was then divided by the diluted share count to arrive at equity value per share. All market data used by J.P. Morgan in its analyses was as of June 28, 2016. Accordingly, this information may not reflect current or future market conditions. In addition, as each ADS represents five underlying Shares, all calculations of equity value per common share or implied equity value per common share below represent the value attributable to 0.2 ADSs.

Discounted Cash Flow Analysis

J.P. Morgan conducted a discounted cash flow analysis for the purpose of determining the [diluted] equity value per share. A discounted cash flow analysis is a method of evaluating an asset using estimates of the future unlevered free cash flows generated by the asset and taking into consideration the time value of money with respect to those future cash flows by calculating their “present value.” “Present value” refers to the current value of one or more future cash payments from the asset, which is referred to as that asset’s cash flows, and is obtained by discounting those cash flows back to the present using a discount rate that takes into account macro-economic assumptions and estimates of risk, the opportunity cost of capital, capitalized returns and other appropriate factors. “Terminal value” refers to the capitalized value of all cash flows from an asset for periods beyond the final forecast period.

J.P. Morgan calculated the unlevered free cash flows that the Company is expected to generate during fiscal years 2016 to 2025 based upon financial projections prepared by the management of the Company. See “Special Factors—Certain Financial Projections” beginning on page 42 for additional information.

J.P. Morgan also calculated a range of terminal asset values of the Company at the end of the projection period ended 2025 by applying a perpetual growth rate ranging from 1.25% to 1.75%. The perpetual growth rate range was selected based on a combination of macro-economic factors, such as general industry trends and expected inflation rates, and the professional judgment of J.P. Morgan. The unlevered free cash flows and the range of terminal asset values were then discounted to present values using a range of discount rates from 9.0% to 10.0%, which were chosen by J.P. Morgan based upon an analysis of the weighted average cost of capital of the Company. The present value of the unlevered free cash flows and the range of terminal asset values were then adjusted by subtracting total debt outstanding as of March 31, 2016 (excluding the Company’s US$400 million convertible bonds from total debt if the implied per share price under respective methodologies is higher than the estimated conversion price of NT$45.75 per share), subtracting total unconsolidated investments as of March 31, 2016 (including the total available-for-sale financial assets and long-term investments under equity method), and adding pro-forma cash and cash equivalents (cash and cash equivalents as of March 31, 2016 adjusted by subtracting dividend payable for the dividends announced on May 16, 2016) to arrive at equity value for the Company. Based on these assumptions, the discounted cash flow analysis indicated a range of per share equity values of between NT$46.20 and NT$54.41.

47

Public Trading Multiples Analysis

Using publicly available information, J.P. Morgan compared selected financial data of the Company with similar data for selected publicly traded companies engaged in businesses which J.P. Morgan judged to be most similar to the Company. The companies selected by J.P. Morgan were:

Advanced Semiconductor Engineering, Inc.

Powertech Technology, Inc.

Amkor Technology, Inc.

Chipbond Technology Corporation

These companies were selected, among other reasons, because they represent the main publicly traded peers in the Outsourced Semiconductor Assembly and Test industry with operations and businesses that, for purpose of J.P. Morgan’s analysis, may be considered similar to that of the Company. However, none of the selected companies reviewed is identical to the Company. Accordingly, a complete analysis of the results of the following calculations cannot be limited to a quantitative review of such results and involves complex considerations and judgments concerning the differences in the financial and operating characteristics of the selected companies compared to the Company’s and other factors that could affect the public trading value of the selected companies and the Company.

In all instances, multiples were based on closing share prices on June 28, 2016. For each of the following analyses performed by J.P. Morgan, estimated financial data for the selected companies were based on the selected companies’ filings with the SEC and any other relevant stock exchanges as well as the publicly available consensus estimates of Wall Street analysts, and estimated financial data for the Company was based on the financial projections prepared by the management of the Company. See “Special Factors—Certain Financial Projections” beginning on page 42 for additional information.

In conducting its analyses, J.P. Morgan reviewed the selected companies’ trading multiples based on (1) the ratio of EV to estimated earnings before interest, taxes, depreciation and amortization (“EBITDA”) for calendar year 2016, (2) the ratio of EV to estimated EBITDA for calendar year 2017 and (3) the ratio of equity value to book value as of March 31, 2016, referred to as the P/B multiple. Results of the analyses were presented for the selected companies, as indicated in the following table:

|  | EV/EBITDA |  |  |  |
|  | CY 2016E |  |  | CY 2017E |  |  | P/B |
Advanced Semiconductor Engineering, Inc. |  |  | 5.6x |  |  |  | 5.3x |  |  |  | 1.8x |
Powertech Technology, Inc. |  |  | 3.6x |  |  |  | 3.3x |  |  |  | 1.6x |
Amkor Technology, Inc. |  |  | 3.4x |  |  |  | 2.8x |  |  |  | 1.1x |
Chipbond Technology Corporation |  |  | 5.2x |  |  |  | 4.6x |  |  |  | 1.1x |

48

Based on the above analyses, J.P. Morgan applied a multiple reference range of (1) 1.1x to 1.8x for equity value to the Company’s book value, which is based on the Company’s book value as of March 31, 2016 adjusted by (i) including the Company’s US$400 million convertible bonds as part of equity if the implied per share price is higher than the estimated conversion price of NT$45.75 per share and (ii) subtracting dividends payable of NT$11.8 billion for the dividends announced on May 16, 2016, (2) 3.4x to 5.6x for EV to the Company’s estimated EBITDA for calendar year 2016 based on management estimates, and (3) 2.8x to 5.3x for EV to the company’s estimated EBITDA for calendar year 2017 based on management estimates. In comparison to the per common share consideration, the analyses indicated the following equity values per common share:

P/B |  | EV/EBITDA 2016E |  | EV/EBITDA 2017E
NT$21.38 to NT$34.98 |  | NT$25.80 to NT$43.57 |  | NT$23.65 to NT$46.28

Other Analysis for Information Purpose Only

J.P. Morgan noted that historical stock trading and precedent transaction multiple analyses are not valuation methodologies but were presented merely for informational purposes.

The closing price of the Company on May 13, 2016 was NT$44.85 per share. The trading range of closing prices for the Company for the 52-week period ended May 13, 2016 was between NT$33.10 and NT$52.70 per share. May 13, 2016 was the last trading date immediately prior to May 16, 2016, on which date Taiwan local media reported that recent communications between ASE and the Company prompted speculation that ASE’s tender offer on the Company’s remaining shares could be revived.

J.P. Morgan also conducted an analysis of selected transactions in the Asia Outsourced Semiconductor Assembly and Test industry. For each of the selected transactions, J.P. Morgan calculated, to the extent information was publicly available, (1) the enterprise value of the target company divided by the target company’s EBITDA for the 12 months ended the last financial reporting date prior to the announcement of the respective transactions, or “LTM EV/EBITDA, ” and (2) equity value divided by book value as of the last financial reporting date prior to the announcement of the respective transaction, or “P/B”. The transaction reviewed, the date each transaction was announced, and the resulting LTM EV/EBITDA and P/B are as follows:

Announcement Date |  | Target |  | Acquiror |  | Stake Acquired |  |  | Equity Value |  |  | Enterprise Value |  |  | LTM EV / EBITDA |  |  | P / B |
Sept 4, 2007 |  | ASE Test |  | Advanced Semi-conductor Engineering |  |  | 53.5 | % |  |  | 1,538 |  |  |  | 1,225 |  |  |  | 6.1x |  |  |  | 1.7x |
June 26, 2007 |  | UTAC |  | Affinity Partners |  |  | 100.0 | % |  |  | 1,417 |  |  |  | 1,452 |  |  |  | 5.7x |  |  |  | 1.7x |

Based on the result of this analysis, J.P. Morgan observed a range of 5.7x to 6.1x LTM EV/ EBITDA and 1.7x P/B, which imply an equity value per share of NT$44.30 to NT$44.47 and NT$33.04, respectively, when applied to the LTM EBITDA and book value of the Company as of March 31, 2016. In comparison, at the Final Per Share Consideration, the implied LTM EV/EBITDA and implied P/B are 6.6x and 2.4x, respectively. Adjustments were made for (1) the Company’s US$400 million convertible bond converting to equity at an estimated conversion price of NT$45.75 per share if the implied per share price is higher than the estimated conversion price and (2) dividends payable of NT$11.8 billion for the dividends announced on May 16, 2016.

In addition, J.P. Morgan observed that on August 21, 2015, ASE announced a tender offer to purchase up to approximately 24.99% of the outstanding share capital of the Company for NT$45 per Share or NT$225 per ADS, which implies an LTM EV/EBITDA of 5.1x and P/B of 2.2x. Adjustments were made for dividends payable of NT$9.3 billion for the dividends announced on June 16, 2015.

49

When conducting a fairness analysis, it is J.P. Morgan’s standard practice to review various potential valuation methodologies and select those valuation methodologies that are most suitable for the transaction in question. J.P. Morgan believes that such review not only could enhance the quality of the valuation analysis but is also necessary and advisable given the wide range of valuation methodologies that are available. Such review and analyses and any determination to select certain but not other valuation methodologies necessarily involve complex considerations and judgments concerning differences in the theoretical basis and characteristics of the valuation methodologies, financial and operational characteristics of the companies involved, the history and background of the transaction in question, the identity of the parties involved and other factors that could affect the accuracy or suitability of the valuation methodologies. For example, the multiples applied in precedent transactions as a valuation methodology may be subject to distortion by factors including (without limitation) the competitive dynamic in the precedent transaction, the conditions and prospects of the industries and geographical regions in which companies involved in the precedent transactions operate, and the specific circumstances and growth prospects of such companies, and therefore may or may not produce reliable reference points for the transaction currently being analyzed. Similarly, historical stock prices of the subject company may also be subject to distortion by factors including (without limitation) historical events that may no longer be relevant to the company’s current value, as well as various other factors that could affect the stock prices of publicly traded companies.

However, J.P. Morgan presented certain data relevant to certain valuation methodologies for informational purposes only even though such methodologies were not selected as valuation methodologies in its fairness analysis, because, among other reasons, (i) such presentation demonstrates the scope of J.P. Morgan’s analysis and that it considered these valuation methodologies, which could be useful to the Board’s evaluation of J.P. Morgan’s advice and (ii) J.P. Morgan recognizes that the Board’s determination on whether or not to pursue any particular strategic alternative of the Company necessarily takes into account various factors beyond just the fairness, from a financial point of view, of the consideration payable in any transaction being evaluated, and therefore, although the data presented were not directly used as the basis of J.P. Morgan’s fairness analysis, such data could nonetheless be useful to the Board’s decision-making process.

The foregoing summary of certain material financial analyses does not purport to be a complete description of the analyses or data presented by J.P. Morgan. The preparation of a fairness opinion is a complex process and is not necessarily susceptible to partial analysis or summary description. J.P. Morgan believes that the foregoing summary and its analyses must be considered as a whole and that selecting portions of the foregoing summary and these analyses, without considering all of its analyses as a whole, could create an incomplete view of the processes underlying the analyses and its opinion. In arriving at its opinion, J.P. Morgan did not attribute any particular weight to any analyses or factors considered by it and did not form an opinion as to whether any individual analysis or factor (positive or negative), considered in isolation, supported or failed to support its opinion. Rather, J.P. Morgan considered the totality of the factors and analyses performed in determining its opinion.

Analyses based upon forecasts of future results are inherently uncertain, as they are subject to numerous factors or events beyond the control of the parties and their advisors. Accordingly, forecasts and analyses used or made by J.P. Morgan are not necessarily indicative of actual future results or, should the Share Purchase fail to be consummated, the future value of the shares, which may be significantly more or less favorable than suggested by those analyses. Moreover, J.P. Morgan’s analyses are not and do not purport to be appraisals or otherwise reflective of the prices at which businesses actually could be bought or sold. None of the selected companies reviewed as described in the above summary is identical to the Company. However, the companies selected were chosen because they are publicly traded companies with operations and businesses that, for purposes of J.P. Morgan’s analysis, may be considered similar to those of the Company. The analyses necessarily involve complex considerations and judgments concerning differences in financial and operational characteristics of the companies involved and other factors that could affect the companies compared to the Company.

As a part of its investment banking business, J.P. Morgan and its affiliates are continually engaged in the valuation of businesses and their securities in connection with mergers and acquisitions, investments for passive and control purposes, negotiated underwritings, secondary distributions of listed and unlisted securities, private placements, and valuations for estate, corporate and other purposes. J.P. Morgan was selected to deliver an opinion to the Board with respect to the Share Purchase on the basis of such experience and its familiarity with the Company.

Under the terms of J.P. Morgan’s engagement and for its service, the Company has agreed to pay J.P. Morgan (1) a fee of $3.0 million upon public announcement of the Share Purchase and (2) an additional fee of $2.0 million, payable upon the consummation of the Share Purchase. In addition, the Company has agreed to reimburse J.P. Morgan for its reasonable expenses incurred in connection with its services, including the reasonable fees and expenses of outside legal counsel engaged by J.P. Morgan in connection with its performance of services hereunder. The Company has also agreed to indemnify J.P. Morgan for certain liabilities arising out of J.P. Morgan’s engagement.

In addition, during the two years preceding June 30, 2016 (being the date of its opinion), J.P. Morgan and its affiliates have had, and may continue to have in the future, commercial and/or investment banking relationships with the Company, for which J.P. Morgan and such affiliates have received and may in the future receive customary compensation. Such services during such period have included acting as bookrunner for the Company’s convertible bond offering completed in October 2014 and acting as financial advisor for the Company in connection with ASE’s tender offer for the Company announced in August 2015. As of June 28, 2016 (being the date of its opinion), J.P. Morgan and/or its affiliates own, on a proprietary basis, approximately 0.11% of the outstanding shares of the Company. In the ordinary course of its businesses, J.P. Morgan and its affiliates may actively trade the debt and equity securities of the Company and ASE for its own account or for the accounts of customers and, accordingly, J.P. Morgan and its affiliates may at any time hold long or short positions in such securities.

Opinions of the Special Committee’s Independent Expert

On May 25, 2016, Mr. Hsu, CPA, of IP International, an independent expert engaged by the Special Committee, delivered to the Special Committee the First IP International Opinion that, from a financial point of view, the Original Per Share Consideration to be paid to the holders of the Shares (including the Shares represented by the ADSs) in the Share Purchase, as of May 25, 2016, was fair and reasonable. On June 29, 2016, Mr. Hsu delivered to the Special Committee the Second IP International Opinion that, from a financial point of view, the Original Per Share Consideration (prior to the dividend adjustment) to be paid to the holders of the Shares (including the Shares represented by the ADSs) in the Share Purchase, as of June 29, 2016, was fair and reasonable.

The Special Committee selected Mr. Hsu of IP International to act as an independent expert to provide the IP International Opinions in connection with the Share Purchase based on Mr. Hsu’s reputation and experience in the Taiwan market. No material limitations were imposed by the Special Committee on Mr. Hsu’s work in connection with the Share Purchase.

The full text of the English translation of the IP International Opinions has been included in Annex C to this proxy statement. The IP International Opinions outline the procedures followed, assumptions made, matters considered and qualifications and limitations on the review undertaken by Mr. Hsu in rendering the IP International Opinions. The descriptions of the IP International Opinions set forth below are qualified in their entirety by reference to the full text of such opinions. You are urged to read the entire opinion carefully in connection with your consideration of the Share Purchase.

51

The IP International Opinions speak only as of the date of each such opinion. The IP International Opinions were directed to the Special Committee and are directed only to the fairness of the Original Per Share Consideration. They do not address the underlying business decision of the Company to engage in the Share Purchase and do not constitute advice or a recommendation to any shareholder, or holder of ADSs, of the Company as to how to act or vote with respect to the Share Purchase or any other matter.

In connection with rendering the IP International Opinions, Mr. Hsu reviewed and considered the audited or unaudited financial statements of the Company for the years 2014, 2015 and the first quarter of 2016, relevant business overviews, financial statements, and other materials Mr. Hsu deemed relevant and available to the public from, among other sources, the Market Observation Post System of TWSE, the TWSE and the Taipei Exchange. In performing its review, Mr. Hsu relied upon the accuracy and completeness of all of the financial and other information that was available to Mr. Hsu from public sources or that was otherwise reviewed by Mr. Hsu, and Mr. Hsu assumed such accuracy and completeness for purposes of preparing the IP International Opinions.

Mr. Hsu expressed no opinion as to the trading values of the Shares after the date of each respective IP International Opinion or what the value of the Shares will be upon consummation of the Share Purchase. Mr. Hsu expressed no opinion as to any of the legal, accounting, and tax matters relating to the Share Purchase. The IP International Opinions were necessarily based on financial, economic, market and other conditions as in effect on, and the information made available to Mr. Hsu as of, the date of the respective IP International Opinions. Events occurring after the date thereof could materially affect the IP International Opinions. Mr. Hsu has not undertaken to update, revise, reaffirm or withdraw the IP International Opinions or otherwise comment upon events occurring after the date of the IP International Opinions.

In rendering the IP International Opinions, Mr. Hsu performed a variety of financial analyses. The following is a summary of the material analyses performed by Mr. Hsu in each Opinion, but it is not a complete description of all the analyses underlying each Opinion. The summary includes information presented in tabular format. In order to fully understand the financial analyses, these tables must be read together with the accompanying text. The tables alone do not constitute a complete description of the financial analyses. The preparation of a fairness opinion is a complex process involving subjective judgments as to the most appropriate and relevant methods of financial analysis and the application of those methods to the particular circumstances. The process, therefore, is not necessarily susceptible to a partial analysis or summary description. Mr. Hsu believes that his analyses must be considered as a whole and that selecting portions of the factors and analyses to be considered without considering all factors and analyses could create an incomplete view of the evaluation process underlying his opinion. Also, no company included in Mr. Hsu’s comparative analyses described below is identical to the Company and no transaction is identical to the Share Purchase. Accordingly, an analysis of comparable companies or transactions involves complex considerations and judgments concerning differences in financial and operating characteristics of the companies and other factors that could affect the public trading values of the Company and the companies to which they are being compared.

First IP International Opinion

Mr. Hsu elected for a market-based approach as the primary evaluation method while taking into account other non-quantitative factors to evaluate the reasonableness of the Original Per Share Consideration. Under the market-based approach, Mr. Hsu adopted a (i) market price method (the “Market Value Method”) that analyzed historical market prices of the Shares; (ii) a price-earnings ratio method (the “P/E Ratio Method”) that applied the average price to earnings per share ratios of the Comparable Companies (as defined below) to the Company’s earnings per share as of March 31, 2016; and (iii) a price-book ratio method (the “P/B Ratio Method”) that applied the average price-to-book value ratios of the Comparable Companies to the Company’s net book value for the quarter ended March 31, 2016. Mr. Hsu determined not to use an income-based approach, which requires using a company’s estimates of future cash flows, because such an approach involves multiple assumptions and has a relatively higher level of uncertainty and lesser objectivity as compared to other valuation methods. In addition, Mr. Hsu determined that an asset-based approach was not appropriate for evaluation in light of the Company’s asset composition and revenue stability, and therefore did not use such an approach.

52

Of the semiconductor manufacturing companies listed on the TWSE, four industry peers (collectively, the “Comparable Companies”) set forth in the following table were selected for comparison based on relative similarities in customer attributes, business activities and business mode:

Quoted Entity |  | No. of the stock
Advanced Semiconductor Engineering, Inc. (“ASE”) |  | 2311
Powertech Technology Inc. (“PTI”) |  | 6239
ChipMOS Technologies Inc. (“CMOS”) |  | 8150
King Yuan Electronics Co. (“KYEC”) |  | 2449

In applying the Market Value Method, Mr. Hsu used the Company’s recent public trading prices for the Shares to evaluate the average market closing price for 30, 60 and 90 business days up to, and including, May 25, 2016 to calculate a range of the estimated fair market value per Share as follows:

Item |  | Average per Share price (NT$) |
30-Day Average Closing Price |  |  | 47.93 |
60-Day Average Closing Price |  |  | 49.18 |
90-Day Average Closing Price |  |  | 50.04 |

As shown in the table above, based on the Market Value Method, the estimated fair market value per Share falls in the range of NT$47.93 to NT$50.04, without taking any adjusting factors into account.

In applying the P/E Ratio Method, Mr. Hsu applied the average price to earnings per share ratios of the Comparable Companies (based on earnings per share for the four quarters ended March 31, 2016) to the Company’s earnings per share for the four quarters ended March 31, 2016 to calculate the estimated fair market value per Share, as set forth in the following table.

In applying the P/B Ratio Method, Mr. Hsu applied the average price to book value per share ratios of the Comparable Companies (based on net value per share as of March 31, 2016) to the Company’s net book value per Share as of March 31, 2016 to calculate the estimated fair market value per Share, as set forth in the following table.

Stock No. |  | Comparable Companies |  |  | P/E ratio |  |  | P/B ratio |
2311 |  |  | ASE |  |  |  | 13.17 |  |  |  | 1.60 |
6239 |  |  | PTI |  |  |  | 12.53 |  |  |  | 1.51 |
8150 |  |  | CMOS |  |  |  | 15.33 |  |  |  | 1.51 |
2449 |  |  | KYEC |  |  |  | 14.31 |  |  |  | 1.43 |
Average ratio of the Comparable Companies (A) |  |  |  |  |  |  | 13.84 |  |  |  | 1.51 |
Earnings per Share/Net book value per Share (B) |  |  |  |  |  |  | 2.48 |  |  |  | 23.23 |
Fair market value per Share (C=A*B) (NT$) |  |  |  |  |  |  | 34.32 |  |  |  | 35.08 |

53

As shown in the table above, based on the P/E Ratio Method, the estimated fair market value per Share is NT$34.32, without taking any adjusting factors into account; based on the P/B Ratio Method, the estimated fair market value per Share is NT$35.08, without taking any adjusting factors into account.

Based on the Market Price Method, the P/E Ratio Method and the P/B Ratio Method, Mr. Hsu concluded that the reasonable range of the fair market value per Share is as set forth in the following table:

Valuation Method |  | Fair market value per Share |  |  | Reasonable range of the fair market value per Share prior to the control premium adjustment
Market Value Method (NT$) |  |  | 47.93~50.04 |  |  | 34.32~50.04
P/E Ratio Method (NT$) |  |  | 34.32 |  |
P/B Ratio Method (NT$) |  |  | 35.08 |  |

Mr. Hsu then applied an adjustment of 17.87% to account for the average control premium. The adjusted fair price range per Share is presented in the table below:

Valuation Method |  | Fair market value per Share |  |  | Reasonable range of the fair market value per Share after the control premium adjustment
Market Value Method (NT$) |  |  | 56.50~58.98 |  |  | 40.45~58.98
P/E Ratio Method (NT$) |  |  | 40.45 |  |
P/B Ratio Method (NT$) |  |  | 41.35 |  |

On the basis of this analysis, Mr. Hsu concluded that, as of May 25, 2016, the reasonable price range per Share should be between NT$40.45 and NT$58.98 and the Original Per Share Consideration was fair and reasonable.

Second IP International Opinion

Mr. Hsu elected for a market-based approach as the primary evaluation method while taking into account other non-quantitative factors to evaluate the reasonableness of the Original Per Share Consideration. Under the market-based approach, Mr. Hsu adopted a (i) market price method (the “Market Value Method”) that analyzed historical market prices of the Shares; (ii) a price-earnings ratio method (the “P/E Ratio Method”) that applied the average price to earnings per share ratios of the Comparable Companies to the Company’s earnings per share as of March 31, 2016; and (iii) a price-book ratio method (the “P/B Ratio Method”) that applied the average price-to-book value ratios of the Comparable Companies to the Company’s net book value for the quarter ended March 31, 2016. Mr. Hsu determined not to use an income-based approach, which requires using a company’s estimates of future cash flows, because such an approach involves multiple assumptions and has a relatively higher level of uncertainty and lesser objectivity as compared to other valuation methods. In addition, Mr. Hsu determined that an asset-based approach was not appropriate for evaluation in light of the Company’s asset composition and revenue stability, and therefore did not use such an approach.

Of the semiconductor manufacturing companies listed on the TWSE, four industry peers were selected for comparison based on relative similarities in customer attributes, business activities and business mode: ASE, CMOS, PTI and KYEC.

54

In applying the Market Value Method, Mr. Hsu used the Company’s recent public trading prices for the Shares to evaluate the average market closing price for 30, 60 and 90 business days up to, and including, June 29, 2016 to calculate a range of the estimated fair market value per Share as follows:

Item |  | Average per Share price (NT$) |
Average Price of 30 Days |  |  | 51.23 |
Average Price of 60 Days |  |  | 49.94 |
Average Price of 90 Days |  |  | 50.14 |

As shown in the table above, based on the Market Value Method, the estimated fair market value per Share falls in the range of NT$49.94 to NT$51.23, without taking any adjusting factors into account.

In applying the P/E Ratio Method, Mr. Hsu applied the average price to earnings per share ratios of the Comparable Companies (based on earnings per share for the four quarters ended March 31, 2016) to the Company’s earnings per share for the four quarters ended March 31, 2016 to calculate the estimated fair market value per Share, as set forth in the following table.

In applying the P/B Ratio Method, Mr. Hsu applied the average price to book value per share ratios of the Comparable Companies (based on net value per share as of March 31, 2016) to the Company’s net book value per Share as of March 31, 2016 to calculate the estimated fair market value per Share, as set forth in the following table.

Stock No. |  | Comparable Companies |  |  | P/E ratio |  |  | P/B ratio |
2311 |  |  | ASE |  |  |  | 14.28 |  |  |  | 1.72 |
6239 |  |  | PTI |  |  |  | 13.75 |  |  |  | 1.67 |
8150 |  |  | CMOS |  |  |  | 16.06 |  |  |  | 1.58 |
2449 |  |  | KYEC |  |  |  | 14.48 |  |  |  | 1.46 |
Average ratio of the Comparable Companies (A) |  |  |  |  |  |  | 14.64 |  |  |  | 1.61 |
Earnings per Share/Net book value per Share (B) |  |  |  |  |  |  | 2.48 |  |  |  | 23.23 |
Fair market value per Share (C=A*B) (NT$) |  |  |  |  |  |  | 36.31 |  |  |  | 37.40 |

As shown in the table above, based on the P/E Ratio Method, the estimated fair market value per Share is NT$36.31, without taking any adjusting factors into account; based on the P/B Ratio Method, the estimated fair market value per Share is NT$37.40, without taking any adjusting factors into account.

Based on the Market Price Method, the P/E Ratio Method and the P/B Ratio Method, Mr. Hsu concluded that the reasonable range of the fair market value per Share is as set forth in the following table:

Valuation Method |  | Fair market value per Share |  |  | Reasonable range of the fair market value per Share prior to the control premium adjustment
Market Value Method (NT$) |  |  | 49.94~51.23 |  |  | 36.31~51.23
P/E Ratio Method (NT$) |  |  | 36.31 |  |
P/B Ratio Method (NT$) |  |  | 37.40 |  |

Mr. Hsu then applied an adjustment of 17.87% to account for the average control premium. The adjusted fair price range per Share is presented in the table below:

Valuation Method |  | Fair market value per Share |  |  | Reasonable range of the fair market value per Share prior to the control premium adjustment
Market Value Method (NT$) |  |  | 58.86~60.38 |  |  | 42.80~60.38
P/E Ratio Method (NT$) |  |  | 42.80 |  |
P/B Ratio Method (NT$) |  |  | 44.08 |  |

55

On the basis of this analysis, Mr. Hsu concluded that, as of June 29, 2016, the reasonable price range per Share should be between NT$42.80 and NT$60.38 and the Original Per Share Consideration was fair and reasonable.

Opinions of ASE’s Independent Expert

Crowe Horwath Opinions

On May 25, 2016, Mr. Ji-Sheng Chiu, CPA, of Crowe Horwath (TW) CPAs, an independent expert engaged by ASE, delivered to ASE its written opinion that the proposed exchange of each ASE Share for 0.5 HoldCo Common Shares and each Share for NT$55 in cash pursuant to the Share Purchase was fair and reasonable. On June 29, 2016, Mr. Ji-Sheng Chiu delivered to ASE another written opinion that the proposed exchange of each ASE Share for 0.5 HoldCo Common Shares and each Share for NT$55 in cash pursuant to the Share Purchase was fair and reasonable.

ASE selected Mr. Ji-Sheng Chiu of Crowe Horwath (TW) CPAs to act as an independent expert to provide the Crowe Horwath Opinions in connection with the Share Purchase based on Mr. Ji-Sheng Chiu’s reputation, experience in the Taiwan market and familiarity with ASE and its business. Mr. Ji-Sheng Chiu is regularly engaged in the valuation of businesses and their securities in connection with mergers and acquisitions, private placements and related financings and valuations for corporate and other purposes for ROC corporations. Mr. Ji-Sheng Chiu in the past has delivered opinions to ASE during the two-year period prior to date of the First Crowe Horwath Opinion in connection with (i) a spin-off transaction involving Universal Scientific Industrial Co., Ltd., a subsidiary of ASE, (ii) the Initial ASE Tender Offers, (iii) a private placement under which ASE sold its shareholdings in Universal Scientific Industrial Co., Ltd. to another subsidiary of ASE for corporate restructuring proposes, (iv) the proposal to the Company to acquire 100% of its outstanding shares not owned by ASE in cash dated December 14, 2015 and (v) the Second ASE Tender Offers. Mr. Ji-Sheng Chiu received aggregate compensation of NT$300,000 (US$9,593.9) in connection with these prior opinions and was paid an opinion fee of NT$60,000 (US$1,918.8) for each of the First Crowe Horwath Opinion and the Second Crowe Horwath Opinion. Mr. Ji-Sheng Chiu may in the future deliver opinions to ASE, for which services Mr. Ji-Sheng Chiu may receive compensation. No material limitations were imposed by ASE on Mr. Ji-Sheng Chiu’s work in connection with the Share Purchase.

The full text of the English translation of the Crowe Horwath Opinions have been included in Annex D to this proxy statement (“Share Purchase” in this section “Opinions of ASE’s Independent Expert” stands for “Share Exchange” in Annex D). The Crowe Horwath Opinions will also be available for any interested ASE shareholder (or any representative of an ASE shareholder who has been so designated in writing) to inspect and copy at ASE’s principal executive offices during regular business hours. The Crowe Horwath Opinions outline the procedures followed, assumptions made, matters considered and qualifications and limitations on the review undertaken by Mr. Ji-Sheng Chiu in rendering the Crowe Horwath Opinions. The descriptions of the Crowe Horwath Opinions set forth below are qualified in their entirety by reference to the full text of such opinions. Holders of ASE Shares or the Company Shares are urged to read the entire opinion carefully in connection with their consideration of the Share Purchase.

The Crowe Horwath Opinions speak only as of the date of each such opinion. The Crowe Horwath Opinions were directed to ASE Board and are directed only to the fairness of the proposed exchange of each ASE Share for 0.5 HoldCo Common Shares and each Share for NT$55 in cash pursuant to the Share Purchase. They do not address the underlying business decision of ASE or the Company to engage in the Share Purchase and do not constitute recommendation as to whether or not any holder of Common Shares should vote in favor of the Share Purchase at any shareholder meeting, or at all.

56

In connection with rendering the Crowe Horwath Opinions, Mr. Ji-Sheng Chiu reviewed and considered the audited or unaudited financial statements of ASE and the Company for the years 2014, 2015 and the first quarter of 2016, relevant business overviews, financial statements, and other materials Mr. Ji-Sheng Chiu deemed relevant and available to the public from, among other sources, the TWSE’s Market Observation Post System, the website of the TWSE, the website of the Taipei Exchange (GreTai Securities Market), the Commerce and Industry Registration Enquiry System of the Department of Commerce, Ministry of Economic Affairs, Taiwan, the Taiwan Economic Journal (TEJ) Database, and comparison, analysis and historical stock price data of ASE, the Company, and their peers compiled by Bloomberg. In performing its review, Mr. Ji-Sheng Chiu relied upon the accuracy and completeness of all of the financial and other information that was available to Mr. Ji-Sheng Chiu from public sources or that was otherwise reviewed by Mr. Ji-Sheng Chiu, and Mr. Ji-Sheng Chiu assumed such accuracy and completeness for purposes of preparing the Crowe Horwath Opinions.

Mr. Ji-Sheng Chiu expressed no opinion as to the trading values of ASE Shares or the Company Shares after the date of each respective Opinion or what the value of ASE Shares or Shares will be upon consummation of the Share Purchase. Mr. Ji-Sheng Chiu expressed no opinion as to any of the legal, accounting, and tax matters relating to the Share Purchase. The Crowe Horwath Opinions were necessarily based on financial, economic, market and other conditions as in effect on, and the information made available to Mr. Ji-Sheng Chiu as of, the date of the respective Crowe Horwath Opinions. Events occurring after the date thereof could materially affect the Crowe Horwath Opinions. Mr. Ji-Sheng Chiu has not undertaken to update, revise, reaffirm or withdraw the Crowe Horwath Opinions or otherwise comment upon events occurring after the date of the Crowe Horwath Opinions.

In rendering the Crowe Horwath Opinions, Mr. Ji-Sheng Chiu performed a variety of financial analyses. The following is a summary of the material analyses performed by Mr. Ji-Sheng Chiu in each Opinion, but it is not a complete description of all the analyses underlying each Opinion. The summary includes information presented in tabular format. In order to fully understand the financial analyses, these tables must be read together with the accompanying text. The tables alone do not constitute a complete description of the financial analyses. The preparation of a fairness opinion is a complex process involving subjective judgments as to the most appropriate and relevant methods of financial analysis and the application of those methods to the particular circumstances. The process, therefore, is not necessarily susceptible to a partial analysis or summary description. Mr. Ji-Sheng Chiu believes that its analyses must be considered as a whole and that selecting portions of the factors and analyses to be considered without considering all factors and analyses could create an incomplete view of the evaluation process underlying its opinion. Also, no company included in Mr. Ji-Sheng Chiu’s comparative analyses described below is identical to the Company and no transaction is identical to the Share Purchase. Accordingly, an analysis of comparable companies or transactions involves complex considerations and judgments concerning differences in financial and operating characteristics of the companies and other factors that could affect the public trading values of the Company and the companies to which they are being compared.

First Crowe Horwath Opinion

Consideration for ASE Shares

Mr. Ji-Sheng Chiu evaluated the proposed exchange of each ASE Share for 0.5 HoldCo Common Shares pursuant to Share Purchase. Mr. Ji-Sheng Chiu used the equity attributable to owners of parent of ASE based on the audited or unaudited consolidated financial statements of ASE (NT$158,016,614,000 as of March 31, 2016) and the total issued ASE Shares based on the latest update from the Commerce and Industry Registration Enquiry System of Department of Commerce, Ministry of Economic Affairs, Taiwan (7,918,272,896 as of April 26, 2016) to calculate a net book value per share of NT$19.956. Under the Share Purchase, 7,918,272,892 ASE Shares would result in 3,959,136,448 as of the Effective Time. The net book value per HoldCo Common Share was calculated based on ASE’s equity attributable to owners of parent as of March 31, 2016 to be NT$39.912 per share. Mr. Ji-Sheng Chiu concluded that the shareholders’ equity for the holders of HoldCo Common Shares would not be impaired in any way by the exchange ratio of 0.5 HoldCo Common Shares for each ASE Share.

57

The fact that the net value of ASE’s equity attributable to owners of parent as of the Effective Time may vary from that as of March 31, 2016 was also considered. However, since the shareholders of ASE will contribute will contribute all the ASE Shares as of the Effective Time in exchange for all the HoldCo Common Shares, Mr. Ji-Sheng Chiu concluded that the shareholders’ equity for the holders of HoldCo Common Shares will not be affected as a result of the Share Purchase.

Based on this analysis, Mr. Ji-Sheng Chiu concluded that, as of May 25, 2016, the proposed exchange of each ASE Share for 0.5 HoldCo Common Shares pursuant to the Share Purchase was fair and reasonable.

Consideration for Shares

Mr. Ji-Sheng Chiu elected for a market approach as the primary evaluation method while taking into account other non-quantitative factors to evaluate the reasonableness of the proposed exchange of each Share for NT$55 in cash pursuant to the Share Purchase. Under the market approach, Mr. Ji-Sheng Chiu adopted a (i) market price method that analyzed historical market prices of the Shares; (ii) a price-book ratio method that applied the average price-to-book value ratios of the Comparison Group (as defined below) to the Company’s book value for the quarter ended March 31, 2016; and (iii) a price-earnings ratio method that applied the average price to earnings per share ratios of the Comparison Group to the Company’s earnings per share for the four quarters ended March 31, 2016. Mr. Ji-Sheng Chiu determined not to use an income approach, which requires using a company’s estimates for future cash flows, because such an approach involves multiple assumptions and has a relatively higher level of uncertainty and lesser objectivity as compared to other valuation methods. In addition, Mr. Ji-Sheng Chiu determined that a cost approach was not appropriate for evaluation in light of the Company’s operating model and capital structure, and therefore did not use such an approach.

Of the semiconductor manufacturing companies listed on the TWSE, three industry peers were selected for comparison based on relative similarities in customer attributes, business activities and business mode: ChipMOS TECHNOLOGIES (Bermuda) LTD. (“ChipMOS”); Chipbond Technology Corporation (“Chipbond”); and Powertech Technology Inc. (“Powertech,” and together with ChipMOS and Chipbond, the “Comparison Group”).

In applying the market price method, Mr. Ji-Sheng Chiu used the Company’s recent public trading prices for Shares to evaluate the average market closing price for 60, 90 and 180 business days up to, and including, May 25, 2016 to calculate a range of theoretical values for Shares as follows:

Items |  | Average closing price |  |  | Theoretical price range
|  |  |  |  | Prices in NT$
Latest 60 business days |  |  | 49.18 |  |  | 47.13 - 50.04
Latest 90 business days |  |  | 50.04 |  |
Latest 180 business days |  |  | 47.13 |  |

Note: | Sources of ex-rights/ex-dividend adjusted closing prices are from compilations of Taiwan Economic Journal (2015/8/28 - 2016/5/25); all average prices are calculated by simple arithmetic averaging.

58

As shown in the table above, based on the market price method, the theoretical value per Share falls in the range of NT$47.13 to NT$50.04, without taking any adjusting factors into account.

In applying the price-book ratio method, Mr. Ji-Sheng Chiu used the book value per Share and the average price-to-book value ratios of the Comparison Group along with average closing prices for 180 days up to, and including, May 25, 2016 to calculate price-to-book value ratios of the Comparison Group and to calculate a range of values for Shares as follows:

Comparing to peer companies |  | Average closing prices in latest 180 business days |  |  | Net value per share for the first half of 2016 |  |  | Price-book value ratio |
|  | Prices in NT$ |
ChipMOS |  |  | 32.53 |  |  |  | 21.20 |  |  |  | 1.53 |
Chipbond |  |  | 47.86 |  |  |  | 36.31 |  |  |  | 1.32 |
Powertech |  |  | 66.98 |  |  |  | 44.48 |  |  |  | 1.51 |

Note: | Sources of ex-rights/ex-dividend adjusted closing prices are from compilations of Taiwan Economic Journal (2015/8/28 - 2016/5/25); all average prices are calculated by simple arithmetic averaging.

Items |  | Descriptions
|  | Prices in NT$
Range of multipliers |  | 1.32 - 1.53 times
Net value per Share for the first quarter of 2016 |  | 23.23
Theoretical price range |  | 30.66 - 35.54

As shown in the table above, based on the price-to-book value ratio method, the theoretical price per Share falls in the range of NT$30.66 to NT$35.54, without taking any adjusting factors into account.

In applying the price-earnings ratio method, Mr. Ji-Sheng Chiu applied the price to earnings per share ratios of the Comparison Group (based on earnings per share for the four quarters ended March 31, 2016 and the average closing prices for 180 days up to, and including, May 25, 2016) to the Company’s earnings per share for the four quarters ended March 31, 2016 to calculate a range of values for Shares as follows:

Comparing to peer companies |  | Average closing prices in latest 180 business days |  |  | Earnings per share in the four quarters ended March 31, 2016 |  |  | Price-earnings ratio |
|  | Prices in NT$ |
ChipMOS |  |  | 32.53 |  |  |  | 2.09 |  |  |  | 15.56 |
Chipbond |  |  | 47.86 |  |  |  | 2.64 |  |  |  | 18.13 |
Powertech |  |  | 66.98 |  |  |  | 5.37 |  |  |  | 12.47 |

Note: | Sources of ex-rights/ex-dividend adjusted closing prices are from compilations of Taiwan Economic Journal (2015/8/28 - 2016/5/25); all average prices are calculated by simple arithmetic averaging.

Items |  | Descriptions
|  | Prices in NT$
Range of multipliers |  | 12.47 – 18.13 times
Consolidated earnings per Share |  | 2.49
Theoretical price range |  | 31.05 – 45.14

As shown in the table above, based on the price to earnings per share ratio method, the theoretical price range per Share falls in the range of NT$31.05 to NT$45.14, without taking any adjusting factors into account.

59

Mr. Ji-Sheng Chiu, after taking into account certain non-quantitative key factors, weighted each of the three methods described above equally to obtain a theoretical price per Share, as set forth below:

Evaluation Method |  | Price range per Share |  | Weight |  |  | Theoretical price range per Share
|  | Prices in NT$
Market Price Method |  | 47.13 - 50.04 |  |  | 33.3 | % |  | 36.28 - 43.57
Price-book Ratio Method |  | 30.66 - 35.54 |  |  | 33.3 | % |
Price-earnings Ratio Method |  | 31.05 - 45.14 |  |  | 33.3 | % |

Mr. Ji-Sheng Chiu then applied an adjustment of 33.24% to account for the average premium paid in mergers involving the global semiconductor industry since the third quarter of 2015. The adjusted price range per Share is presented in the table below:

Evaluation Method |  | Price range per Share |  | Adjusted price range per Share
|  | Prices in NT$
The weighted average of the results under the Market Price, Price-to-book and the Price to Earnings Methods |  | 36.28 - 43.57 |  | 48.34 - 58.05

On the basis of this analysis, Mr. Ji-Sheng Chiu concluded that, as of May 25, 2016, the reasonable price range per Share should be between NT$48.34 and NT$58.05 and the proposed exchange of each Share for NT$55 in cash pursuant to the Share Purchase was fair and reasonable.

Second Crowe Horwath Opinion

Consideration for ASE Shares

Mr. Ji-Sheng Chiu evaluated the proposed exchange of each ASE Share for 0.5 HoldCo Common Shares pursuant to Share Purchase. Mr. Ji-Sheng Chiu used the equity attributable to owners of parent of ASE based on the audited or reviewed consolidated financial statements of ASE (NT$158,016,614,000 as of March 31, 2016) and the total issued ASE Shares based on the latest update from the Commerce and Industry Registration Enquiry System of Department of Commerce, Ministry of Economic Affairs, Taiwan (7,918,272,896 as of April 26, 2016) to calculate a net book value per share of NT$19.956. Under the Share Purchase, 7,918,272,892 ASE Shares would result in 3,959,136,448 as of the Effective Time. The net book value per HoldCo Common Share was calculated based on ASE’s equity attributable to owners of parent as of March 31, 2016 to be NT$39.912 per share. Mr. Ji-Sheng Chiu concluded that the shareholders’ equity for the holders of HoldCo Common Shares would not be impaired in any way by the exchange ratio of 0.5 HoldCo Common Shares for each ASE Share.

The fact that the net value of ASE’s equity attributable to owners of parent as of the Effective Time may vary from that as of March 31, 2016 was also considered. However, since the shareholders of ASE will contribute all the ASE Shares as of the Effective Time in exchange for all the HoldCo Common Shares, Mr. Ji-Sheng Chiu concluded that the shareholders’ equity for the holders of HoldCo Common Shares will not be affected as a result of the Share Purchase.

Based on this analysis, Mr. Ji-Sheng Chiu concluded that, as of June 29, 2016, the proposed exchange of each ASE Share for 0.5 HoldCo Common Shares pursuant to the Share Purchase was fair and reasonable.

Consideration for Shares

Mr. Ji-Sheng Chiu elected for a market approach as the primary evaluation method while taking into account other non-quantitative factors to evaluate the reasonableness of the proposed exchange of each Share for the Final Per Share Consideration pursuant to the Share Purchase. Under the market approach, Mr. Ji-Sheng Chiu adopted a (i) market price method that analyzed historical market prices of the Shares; (ii) a price-book ratio method that applied the average price-to-book value ratios of the Comparison Group (as defined below) to the Company’s book value for the quarter ended March 31, 2016; and (iii) a price-earnings ratio method that applied the average price to earnings per share ratios of the Comparison Group to the Company’s earnings per share for the four quarters ended March 31, 2016. Mr. Ji-Sheng Chiu determined not to use an income approach, which requires using a company’s estimates for future cash flows, because such an approach involves multiple assumptions and has a relatively higher level of uncertainty and lesser objectivity as compared to other valuation methods. In addition, Mr. Ji-Sheng Chiu determined that a cost approach was not appropriate for evaluation in light of the Company’s operating model and capital structure, and therefore did not use such an approach.

Of the semiconductor manufacturing companies listed on the TWSE, Mr. Ji-Sheng Chiu selected the Comparison Group for comparison based on relative similarities customer attributes, business activities and business model.

In applying the market price method, Mr. Ji-Sheng Chiu used the Company’s recent public trading prices for Shares to evaluate the average market closing price for 60, 90 and 180 business days up to, and including, June 29, 2016 to calculate a range of theoretical values for Shares as follows:

Items |  | Average closing price |  |  | Theoretical price range
|  | Prices in NT$
Latest 60 business days |  |  | 46.25 |  |  | 45.05 – 46.45
Latest 90 business days |  |  | 46.45 |  |
Latest 180 business days |  |  | 45.05 |  |

Note: | Sources of ex-rights/ex-dividend adjusted closing prices are from compilations of Taiwan Economic Journal (2015/10/5 - 2016/6/29); all average prices are calculated by simple arithmetic averaging.

As shown in the table above, based on the market price method, the theoretical value per Share falls in the range of NT$45.05 to NT$46.45, without taking any adjusting factors into account.

In applying the price-book ratio method, Mr. Ji-Sheng Chiu used the book value per Share and the average price-to-book value ratios of the Comparison Group along with average closing prices for 180 days up to, and including, June 29, 2016 to calculate price-to-book value ratios of the Comparison Group and to calculate a range of values for Shares as follows:

Comparing to peer companies |  | Average closing prices in latest 180 business days |  |  | Net value per share for the first half of 2016 |  |  | Price-book value ratio |
|  | Prices in NT$ |
ChipMOS |  |  | 32.53 |  |  |  | 21.20 |  |  |  | 1.53 |
Chipbond |  |  | 46.86 |  |  |  | 36.31 |  |  |  | 1.29 |
Powertech |  |  | 65.31 |  |  |  | 44.48 |  |  |  | 1.47 |

Note: | Sources of ex-rights/ex-dividend adjusted closing prices are from compilations of Taiwan Economic Journal (2015/10/5 - 2016/6/29); all average prices are calculated by simple arithmetic averaging.

Items |  | Descriptions
|  | Prices in NT$
Range of multipliers |  | 1.29 – 1.53 times
Net value per Share for the first quarter of 2016 |  | 23.23
Theoretical price range |  | 29.97 – 35.54

As shown in the table above, based on the price-to-book value ratio method, the theoretical price per Share falls in the range of NT$29.97 to NT$35.54, without taking any adjusting factors into account.

61

In applying the price-earnings ratio method, Mr. Ji-Sheng Chiu applied the price to earnings per share ratios of the Comparison Group (based on earnings per share for the four quarters ended March 31, 2016 and the average closing prices for 180 days up to, and including, June 29, 2016) to the Company’s earnings per share for the four quarters ended March 31, 2016 to calculate a range of values for Shares as follows:

Comparing to peer companies |  | Average closing prices in latest 180 business days |  |  | Earnings per share in the four quarters ended March 31, 2016 |  |  | Price-earnings ratio |
|  | Prices in NT$ |
ChipMOS |  |  | 32.53 |  |  |  | 2.09 |  |  |  | 15.56 |
Chipbond |  |  | 46.86 |  |  |  | 2.64 |  |  |  | 17.75 |
Powertech |  |  | 65.31 |  |  |  | 5.37 |  |  |  | 12.16 |

Note: | Sources of ex-rights/ex-dividend adjusted closing prices are from compilations of Taiwan Economic Journal (2015/10/5 - 2016/6/29); all average prices are calculated by simple arithmetic averaging.

Items |  | Descriptions
|  | Prices in NT$
Range of multipliers |  | 12.16 – 17.75 times
Consolidated earnings per Share |  | 2.49
Theoretical price range |  | 30.28 – 44.20

As shown in the table above, based on the price to earnings per share ratio method, the theoretical price range per Share falls in the range of NT$30.28 to NT$44.20, without taking any adjusting factors into account.

Mr. Ji-Sheng Chiu, after taking into account certain non-quantitative key factors, weighted each of the three methods described above equally to obtain a theoretical price per Share, as set forth below:

Evaluation Method |  | Price range per Share |  | Weight |  |  | Theoretical price range per Share
|  | Prices in NT$
Market Price Method |  | 45.05 – 46.45 |  |  | 33.3 | % |  | 35.10 – 42.06
Price-book Ratio Method |  | 29.97 – 35.54 |  |  | 33.3 | % |
Price-earnings Ratio Method |  | 30.28 – 44.20 |  |  | 33.3 | % |

Mr. Ji-Sheng Chiu then applied an adjustment of 33.86% to account for the average premium paid in mergers involving the global semiconductor industry since the third quarter of 2015. The adjusted price range per Share is presented in the table below:

Evaluation Method |  | Price range per Share |  | Adjusted price range per Share
|  | Prices in NT$
The weighted average of the results under the Market Price, Price-to-book and the Price to Earnings Methods |  | 35.10 – 42.06 |  | 46.98 – 56.30

On the basis of this analysis, Mr. Ji-Sheng Chiu concluded that, as of June 29, 2016, the reasonable price range per Share should be between NT$46.98 and NT$56.30 and the proposed exchange of each Share for the Final Per Share Consideration pursuant to the Share Purchase was fair and reasonable.

Effects of the Share Purchase on the Company

Private Ownership

The Company’s ADSs are currently listed on NASDAQ under the symbol “SPIL.” It is expected that, immediately following the completion of the Share Purchase, the Company will cease to be a publicly-traded company and will instead become a privately held company owned directly by HoldCo. Following the completion of the Share Purchase, the ADSs will cease to be listed on NASDAQ, and price quotations with respect to sales of the ADSs in the public market will no longer be available. In addition, registration of the Company’s ADSs and the underlying Shares under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), will be terminated. After the Effective Time, the Company will no longer be required to file periodic reports with the SEC or otherwise be subject to the U.S. federal securities laws, including the Sarbanes-Oxley Act, applicable to public companies. After the completion of the Share Purchase, our shareholders will no longer enjoy the rights or protections that the U.S. federal securities laws provide.

Upon completion of the Share Purchase, each Share issued immediately prior to the effective time, including the Shares beneficially owned by ASE and the treasury shares, but other than the Dissenting Shares (please see “Dissenter’s Rights” beginning on page 93), will be transferred to HoldCo in exchange for the right to receive the Final Per Share Consideration, and each ADS, representing five Shares, including the ADSs beneficially owned by ASE, will represent the right to receive, through the ADS Depositary, the Final Per ADS Consideration, respectively, without interest and net of any applicable withholding taxes. As a result, current shareholders and ADS holders of the Company will no longer have any equity interest in, or be shareholders or ADS holders of, the Company upon completion of the Share Purchase. As a result, our shareholders and ADS holders will not have the opportunity to participate in the earnings and growth of the Company and they will not have the right to vote on corporate matters following the completion of the Share Purchase. Similarly, our current shareholders and ADS holders will not be exposed to the risk of loss in relation to their investment in the Company.

Directors and Management of the Surviving Company

Upon completion of the Share Purchase, the directors of the Company will continue to serve as directors for their respective terms, and ASE has undertaken to reelect or appoint the directors whose terms end in June 2017, if they have not been found to violate their respective fiduciary duties. Mr. Lin, the Company’s chairman, and Mr. Chi-Wen Tsai, the Company’s president, are expected to serve as directors of the HoldCo. The directors of the Company are also authorized to retain the executive officers of the Company as long as the fiduciary duties of the directors can be discharged.

Primary Benefits and Detriments of the Share Purchase

The primary benefits of the Share Purchase to the Company’s shareholders and ADS holders include, without limitation, the following:

| • |  | the Original Per Share Consideration and the Original Per ADS Consideration offered to the holders of Shares and ADSs represent a premium of 8.9% and 12.3%, respectively, over the closing price of NT$50.5 per Share and $7.52 per ADS, respectively, on the Last Trading Day, and a premium of 17.4% and 10.3%, respectively, over the Company’s one-month and three-month volume-weighted average price of NT$46.86 and NT$49.85, respectively, as quoted by the TWSE on the Last Trading Day, and a premium of 19.7% and 11.6%, respectively, over the Company’s one-month and three-month volume-weighted average price of $7.06 and $7.57, respectively, as quoted by NASDAQ on the Last Trading Day; and

| • |  | the all-cash Share Purchase consideration, which will allow our shareholders and ADS holders to immediately realize liquidity for their investment and provide them with certainty of the value of their Shares or ADSs.

63

The primary detriments of the Share Purchase to the Company’s shareholders and ADS holders include, without limitation, the following:

| • |  | the shareholders and ADS holders will have no ongoing equity participation in the Company following the Share Purchase, and they will cease to participate in our future earnings or growth, if any, or to benefit from increases, if any, in the value of the Shares, and will not participate in any potential future sale of the Company to a third party or any potential recapitalization of the Company which could include a dividend to shareholders;

| • |  | the inability to participate in any potential future sale of part or all of the Company following the Share Purchase to one or more purchasers at a valuation higher than that being paid in the Share Purchase; and

| • |  | the taxability of an all-cash transaction to our shareholders and ADS holders who are U.S. Holders (as defined under “Material U.S. Federal Income Tax Considerations”) for U.S. federal income tax purposes.

The Company’s Net Book Value and Net Earnings

The table below sets out the indirect interest in the Company’s net book value and net earnings for ASE before and after the Share Purchase, based on the historical net book value and net earnings of the Company as of and for the year ended December 31, 2015.

Name |  | Ownership Prior to the Share Purchase |  |  | Ownership After the Share Purchase |
|  | Net Book Value |  |  | Earnings |  |  | Net Book Value |  |  | Earnings |
|  | (in millions) |  |  | % |  |  | (in millions) |  |  | % |  |  | (in millions) |  |  | % |  |  | (in millions) |  |  | % |
| NT$ |  |  | US$ |  |  |  | NT$ |  |  | US$ |  |  |  | NT$ |  |  | US$ |  |  |  | NT$ |  |  | US$ |  |
ASE |  |  | 21,113.2 |  |  |  | 675.2 |  |  |  | 33.29 |  |  |  | 2,414.7 |  |  |  | 77.2 |  |  |  | 33.29 |  |  |  | 63,422.0 |  |  |  | 2,028.2 |  |  |  | 100.00 |  |  |  | 7,253.5 |  |  |  | 232.0 |  |  |  | 100.00 |

Plans for the Company after the Share Purchase

Following the completion of the Share Purchase, HoldCo will own 100% of the equity interest in the Company. ASE anticipates that the Company will continue to conduct its operations substantially as they are currently being conducted, except that it will cease to be a publicly-traded company and will instead be a wholly-owned subsidiary of HoldCo.

Subsequent to the completion of the Share Purchase, the Company will no longer be subject to the Exchange Act and NASDAQ compliance and reporting requirements and the related direct and indirect costs and expenses, and may experience positive effects on profitability as a result of the elimination of such costs and expenses.

Except as set forth in this proxy statement and transactions already under consideration by the Company, ASE does not have any current plans, proposals or negotiations that relate to or would result in any of the following:

| • |  | an extraordinary corporate transaction, such as a merger, reorganization, liquidation or relocation of any material operations, involving the Company or any of its subsidiaries;

64

| • |  | the sale or transfer of a material amount of the assets of the Company or any of its subsidiaries; or

| • |  | any other material changes in the Company’s business, including with respect to the Company’s corporate structure or business.

However, the board of directors of HoldCo will continue to evaluate the Company’s entire business and operations from time to time, and may propose or develop plans and proposals which they consider to be in the best interests of the Company and its equity holders, including the disposition or acquisition of material assets, alliances, joint ventures, and other forms of cooperation with third parties or other extraordinary transactions.

Alternatives to the Share Purchase

Alternatives considered by the Company

Following the First ASE Tender Offers, the Company considered a number of alternative transactions to ASE’s proposed acquisition of the Company. The Company entered into a letter of intent with Hon Hai on August 28, 2015, pursuant to which the Hon Hai Share Exchange and Hon Hai Commercial Cooperation were proposed. However, the Capital Increase and By-Law Amendment required for the Hon Hai Exchange and Hon Hai Commercial Cooperation were not approved at the First EGM on October 15, 2015. The Company also proposed to enter into the Tsinghua Transaction with Tsinghua on December 11, 2015, which was terminated after the Board’s consideration on April 28, 2016.

In addition, the Board did not independently determine to initiate a process for the sale of the Company. The Special Committee was engaged in response to the execution of the Share Purchase MOU on May 23, 2016. Since the execution of the Share Purchase MOU on May 26, 2016, the Company has not received any actionable offer from any third party for (a) a merger or consolidation of the Company with another company, (b) the sale or transfer of all or substantially all of the Company’s assets or (c) the purchase of all or a substantial portion of the Shares that would enable such person to exercise control of or significant influence over the Company.

The Special Committee and the Board also took into account that, prior to the consummation of the Share Purchase, if the Company received a bona fide, unsolicited written proposal regarding a competing transaction, and if the Special Committee and the Board both have determined that such acquisition proposal constitutes a Superior Proposal, subject to certain conditions set forth in the Joint Share Exchange Agreement, the Company has certain flexibility to respond to a Superior Proposal, including the ability to negotiate with, propose to, inquire, deliberate with, contact, discuss, offer or consult with such third party, and the Board may change, withhold, withdraw, qualify, amend or modify its recommendation of the Share Purchase to the shareholders of the Company.

Alternatives considered by ASE

Following the concerns reflected in ASE’s November 16, 2015 amendment to its report on Schedule 13D, ASE considered a number of alternative structures and approaches in order to maximize the value of its investment in the Company. These alternatives involved launching the Second ASE Tender Offers or acquiring additional Shares through one or more market purchases or through one or more further tender offers. In addition, had the Second ASE Tender Offers been successfully consummated, ASE had intended to seek to discharge the Board at one or more shareholders’ meetings or await the expiration of the current Board’s term and elect new nominees to the Board, and to subsequently cause the Board to resolve in favor of a transaction proposed by ASE.

65

Following the commencement of discussions and negotiations between ASE and the Company in April 2016, the boards and senior management of ASE and the Company and their respective advisors considered alternative ways of structuring the transaction, including a direct acquisition by ASE of all Shares and ADSs. However, the boards and senior management of each of ASE and the Company concluded that the Share Purchase and establishment of HoldCo was the best way to incentivize healthy internal competition and promote cooperation, improve each company’s operating efficiency, economies of scale as well as research and development and innovation results, and thereby create an environment of mutual assistance and win-win mentality, strengthening competitiveness and improving the performance of HoldCo, with the main goals of improving the quality of customer service, creating shareholders’ value and benefiting the employees.

Effects on the Company If the Share Purchase Is Not Completed

If the Joint Share Exchange Agreement is not approved by the shareholders or if the Share Purchase is not completed for any other reason, shareholders will not receive any payment for their Shares or ADSs in connection with the Share Purchase nor will the holders of any share options receive payment pursuant to the Joint Share Exchange Agreement. Instead, the Company will remain a publicly-traded company with ASE being the largest shareholder, the Shares will continue to be listed and traded on the Taiwan Stock Exchange and the ADSs will continue to be listed and traded on NASDAQ, provided that the Company continues to meet the respective listing requirements of the stock exchanges, and the Company will remain subject to SEC reporting obligations. Therefore, the Company’s shareholders will continue to be subject to similar risks and opportunities as they currently are with respect to their ownership of our Shares or ADSs. Accordingly, if the Share Purchase is not completed, there can be no assurance as to the effect of these risks and opportunities on the future value of your Shares or ADSs, including the risk that the market price of the ADSs may decline to the extent that the current market price reflects a market assumption that the Share Purchase will be completed.

Under specified circumstances in which the Joint Share Exchange Agreement is terminated, the Company may be required to pay a termination fee of NT$17.0 billion. In the event of material defaults by the Company, the Company may be required to pay ASE liquidated damages in the amount of NT$8.5 billion and reimburse ASE and its affiliates for their expenses in connection with the Share Purchase; and in the event of material defaults by ASE, ASE may be required to pay the Company and its affiliates liquidated damages in the amount of NT$8.5 billion and reimburse the Company and its affiliates for their expenses in connection with the Share Purchase, in each case, as described under the caption “The Joint Share Exchange Agreement—Remedies and Liquidated Damages” beginning on page 67.

If the Share Purchase is not completed, from time to time, the Board will evaluate and review, among other things, the business, operations, dividend policy and capitalization of the Company and make such changes as are deemed appropriate and continue to seek to identify strategic alternatives to enhance shareholder value. If the Joint Share Exchange Agreement is not approved by the shareholders or if the Share Purchase is not completed for any other reason, there can be no assurance that any other transaction acceptable to the Company will be offered, or that the business, prospects or results of operations of the Company will not be adversely impacted.

66

Financing

The Company and ASE estimate that the total amount of funds necessary to complete the Share Purchase and the related transactions is anticipated to be approximately NT$173.16 billion, assuming no exercise of dissenters’ rights by shareholders of the Company and ASE. This amount includes the cash to be paid to the Company’s shareholders and holders of ADSs, as well as the related costs and expenses, in connection with the Share Purchase and the related transactions.

The Share Purchase and the related transactions are expected to be funded through a combination of ASE’s cash on hand and debt financing. Subject to the amount of cash on hand at the time when ASE arranges for financing, ASE may arrange bank loans up to NT$173 billion with a combination of a syndication loan of NT$120 billion and a short-term bridge loan of NT$53 billion. In a highly confident letter dated November 7, 2016 issued by Citibank to ASE, Citibank stated that it is highly confident of its ability to arrange debt facilities for the Share Purchase up to an amount of US$3.8 billion equivalent, subject to the terms and conditions set forth in that letter. In another highly confident letter dated November 16, 2016 issued by DBS to ASE, DBS stated that it is confident of its ability to arrange debt facilities for the Share Purchase up to an amount of NT$53 billion, subject to the terms and conditions set forth in that letter. In addition, ASE may enter into other arrangements or transactions, including through a capital increase in cash to reduce the amount of bank loans on or prior to the Effective Time.

Remedies and Liquidated Damage

Upon the occurrence of certain prescribed material events of default, in addition to any right of termination and claims for expenses, the non-defaulting party will also be entitled to liquidated damages in the amount of NT$8.5 billion from the defaulting party, subject to adjustments for contributory negligence by the non-defaulting party. Please see the section entitled “The Joint Share Exchange Agreement—Event of Default, Remedies and Liquidated Damages” for a more complete description of the circumstances under which the Company or ASE may be required to pay liquidated damages to the other party.

Interests of Certain Persons in the Share Purchase

In considering the review conclusions of the Special Committee and the recommendations of our Board with respect to the Share Purchase, you should be aware that ASE has interests in the transaction that are different from, and/or in addition to, the interests of our shareholders generally. The Board and Special Committee were aware of such interests and considered them, among other matters, in reaching their decisions to approve the Joint Share Exchange Agreement and the transactions contemplated by the Joint Share Exchange Agreement, including the Share Purchase, and recommend that our shareholders vote in favor of approving the Joint Share Exchange Agreement and the transactions contemplated by the Joint Share Exchange Agreement, including the Share Purchase.

Interests of ASE

On October 1, 2015, ASE closed its acquisition of, and paid for, 779,000,000 Shares (including those represented by ADSs) at a price of NT$45 per Share and NT$225 per ADS pursuant to the tender offers in the U.S. and in the ROC.

67

In March and April 2016, ASE acquired an additional 258,300,000 Shares (including those represented by ADSs) through open market purchases. The following table sets forth certain information relating to the aforesaid ASE’s open market purchases:

Period |  | Total Number of Shares Purchased |  |  | The Average Price Paid Per Share (in NT$) |  |  | The Range of Price Paid Per Share (in NT$) |

Shares Held by Directors and Executive Officers

As of the date of this proxy statement, our directors and executive officers (as set forth in “Security Ownership of Certain Beneficial Owners and Management of the Company” beginning on page 98), as a group, beneficially own an aggregate of [116,866,101] Shares.

After the completion of the Share Purchase, the maximum amount of cash payments our directors and executive officers may receive in respect of their Shares is approximately $[5,984] million.

The Special Committee

On May 23, 2016, a Special Committee was engaged to consider the proposal from ASE and to take any actions it deems appropriate to assess the fairness and viability of such proposal. The Special Committee was composed of John Hsuan, Tsai-Ding Lin and William W. Sheng. Other than their indemnification and liability insurance rights under the Joint Share Exchange Agreement, none of the members of the Special Committee has a financial interest in the Share Purchase or any of transactions contemplated thereby and none of them is related to ASE. Our Board did not place any limitations on the authority of the Special Committee regarding its investigation and evaluation of the Share Purchase.

Position with the Surviving Company

Upon completion of the Share Purchase, the directors of the Company will continue to serve as directors for their respective terms, and ASE has undertaken to reelect or appoint the directors whose terms end in June 2017, if they have not been found to violate their respective fiduciary duties. Mr. Lin, the Company’s chairman, and Mr. Chi-Wen Tsai, the Company’s president, are expected to serve as directors of the HoldCo. The directors of the Company are also authorized to retain the executive officers of the Company as long as the fiduciary duties of the directors can be discharged.

68

Related Party Transactions

The Company’s audit committee is required to review and approve all related party transactions as defined in Item 404 of Regulation S-K on an ongoing basis. For the years ended December 31, 2014 and 2015, the Company has entered into certain related party transactions, which are further detailed in “Item 7. Major Shareholders and Related Party Transactions,” included in the Company’s Annual Report on Form 20-F for the fiscal year ended December 31, 2015, incorporated by reference into this proxy statement. Please see “Where You Can Find More Information” beginning on page 106 for a description of how to obtain a copy of our Annual Report.

Fees and Expenses

Fees and expenses incurred or to be incurred by the Company and ASE in connection with the Share Purchase are estimated at the date of this proxy statement to be as follows:

Description |  | Amount |
Financing fees and expenses and other professional fees |  | $ | [ | ]
Legal fees and expenses |  | $ | [ | ]
Miscellaneous (including filing fees, printing fees, proxy solicitation fees and mailing costs) |  | $ | [ | ]
Total |  | $ | [ | ]

These expenses will not reduce the Share Purchase consideration to be received by the shareholders of the Company. If the Share Purchase is completed, the party incurring any costs and expenses in connection with the Share Purchase and the Joint Share Exchange Agreement will be responsible for such costs and expenses, except as otherwise provided in the Joint Share Exchange Agreement.

Voting by ASE at the Extraordinary General Meeting

ASE has expressed its intention to vote (or cause to be voted) all of the Shares that it owns to approve the Joint Share Exchange Agreement and the transactions contemplated by the Joint Share Exchange Agreement, including the Share Purchase, and has agreed not to in any manner impede, frustrate or prevent the Share Purchase or any other transactions contemplated by the Joint Share Exchange Agreement. ASE owns 988,847,740 Shares and 9,690,452 ADSs, which represent approximately 33.29% of the total voting power of the Company.

Litigation Related to the Share Purchase

We are not aware of any lawsuit that challenges the Share Purchase, the Joint Share Exchange Agreement or any of the transactions contemplated thereby.

Accounting Treatment of the Share Purchase

The Company will account for the Share Purchase as a transaction between the Company’s shareholders under Taiwan-IFRS or IFRS. From the perspective of the Company’s consolidated financial statements, no special accounting treatment will be applied as a result of the Share Purchase.

69

Regulatory Approvals Required to Complete the Share Purchase

ASE and the Company have each agreed to use their reasonable efforts to obtain all necessary governmental approvals required to complete the Share Purchase. The following is a summary of the regulatory approvals required for the completion of the Share Purchase. As of the date of this proxy statement, TFTC has issued a no objection letter in respect of the Share Purchase. However, there can be no assurance as to if and when regulatory approvals will be obtained in the PRC, if and when the FTC will complete its investigation without seeking an injunction, or the conditions or limitations that such regulatory authorities may seek to impose.

Taiwan Fair Trade Commission Approval

Both ASE and the Company operate in the ROC. Under the ROC Fair Trade Act, transactions involving parties with revenues above certain thresholds cannot be completed until they are reviewed and approved by the TFTC. ASE and the Company submitted the required materials to TFTC on July 29, 2016. TFTC formally accepted the parties’ notification materials on September 19, 2016 and issued a no objection letter in respect of the Share Purchase on November 16, 2016.

United States Antitrust Review

On October 26, 2016, the FTC issued a subpoena and civil investigative demand to ASE and the Company with respect to the transaction contemplated under the Joint Share Exchange Agreement. ASE and the Company are in the process of responding to these requests and fully cooperating with the investigation.

The Ministry of Commerce of the People’s Republic of China

Under the Anti-Monopoly Law of 2008 of the PRC, transactions involving parties with revenues above certain thresholds cannot be completed until they are reviewed and approved by the MOFCOM. ASE and the Company have sufficient revenues in China to exceed the statutory thresholds, and completion of the Share Purchase is therefore conditioned upon MOFCOM’s approval. ASE and the Company submitted the required materials to MOFCOM on August 25, 2016. ASE and the Company are waiting for MOFCOM to formally accept the parties’ notification materials and start Phase I of the review process.

Other Jurisdictions

ASE and the Company derive revenues in other jurisdictions where merger or acquisition control filings or clearances are or may be required. ASE and the Company have sufficient revenues in South Korea and Germany that exceed the statutory thresholds, and completion of the Share Purchase is therefore conditioned upon the approval of the Korea Fair Trade Commission (“KFTC”) and the German Federal Cartel Office (“FCO”). The KFTC cleared the Initial ASE Tender Offers on November 18, 2015. Under the laws of South Korea, the clearance on the Initial ASE Tender Offers extends to the Share Purchase and no additional filing is required. The FCO cleared the Initial ASE Tender Offers on February 1, 2016 and subsequently confirmed that its February 1, 2016 clearance extends to the Share Purchase on July 26, 2016.

Record Date; Shares and ADSs Entitled to Vote

You are entitled to vote at the extraordinary general meeting if you own Shares at the close of business in Taiwan on the Share Record Date for voting at the extraordinary general meeting. On the Share Record Date, [265,676,800] Shares are expected to be issued and outstanding. If you own Shares at the close of business in Taiwan on the Share Record Date, the deadline to lodge your proxy card is , 2017 at a.m. (Taipei time) (being no later than five (5) days before the date of the extraordinary general meeting) and the deadline to exercise your electronic vote is , 2017 at a.m. (Taipei time) (being no later than two (2) days before the date of the extraordinary general meeting). If you own ADSs at the close of business in New York City on the ADS Record Date, you cannot attend or vote at the extraordinary general meeting directly, but you may instruct the ADS Depositary (as the holder of the Shares underlying the ADSs) on how to vote the Shares underlying your ADSs. The ADS Depositary must receive your instructions no later than 5:00 p.m. (New York City time) on , 2017 in order to ensure your Shares are properly voted at the extraordinary general meeting.

However, please be aware that the ADS Depositary, as the record holder of the Shares represented by ADSs, will NOT vote the Shares it holds on deposit at the extraordinary general meeting in accordance with the individual voting instructions it receives. Instead, the ADS Depositary will vote ALL the Shares it holds on deposit at the extraordinary general meeting as follows:

| • |  | if holders of at least 51% of the ADSs outstanding at the close of business in New York City on the ADS Record Date instruct the ADS Depositary to vote in the same manner regarding a resolution, the ADS Depositary will appoint the Voting Representative to vote ALL the Shares represented by the ADSs outstanding in the manner so instructed; and

| • |  | if the ADS Depositary does not receive instructions from holders of at least 51% of the ADSs outstanding at the close of business in New York City on the ADS Record Date, to vote in the same manner regarding a resolution, the ADS Depositary itself will not provide any voting instruction and instead will appoint the Voting Representative to vote ALL the Shares represented by the ADSs outstanding as the Voting Representative deems appropriate, which may not be in your interest.

Alternatively, you may vote at the extraordinary general meeting if you held ADSs as of the ADS Record Date, you cancel your ADSs and you certify that you have not given, and will not give, voting instructions to the ADS Depositary as to the ADSs being cancelled by the close of business in New York City on , 2017, and become a holder of Shares by the close of business in Taiwan on the Share Record Date. Each outstanding Share on the Share Record Date entitles the holder to one vote on each matter submitted to the shareholders for approval at the extraordinary general meeting and any adjournment thereof. See “—Procedures for Voting” below.

Quorum

A quorum of our shareholders is necessary to have a valid shareholders’ meeting. The required quorum for the transaction of business at the extraordinary general meeting is the presence, in person or by proxy, of shareholders holding a simple majority of the issued and outstanding Shares that are entitled to vote on the record date. We expect, as of Share Record Date, there will be [265,676,800] Shares entitled to be voted at the extraordinary general meeting. In the event that a quorum is not present at the extraordinary general meeting, we currently expect that we will adjourn the extraordinary general meeting to solicit additional proxies in favor of the approval of the Joint Share Exchange Agreement.

ADSs

If you own ADSs as of the close of business in New York City on the ADS Record Date, you cannot attend or vote at the extraordinary general meeting directly, but you may instruct the ADS Depositary (as the holder of the Shares underlying the ADSs) how to vote the Shares underlying your ADSs by completing and signing the ADS voting instruction card and returning it in accordance with the instructions printed on it as soon as possible but, in any event, so as to be received by the ADS Depositary no later than 12:00 p.m. (New York City time) on , 2017. However, please be aware that the ADS Depositary, as the record holder of the Shares represented by ADSs, will NOT vote the Shares it holds on deposit at the extraordinary general meeting in accordance with the individual voting instructions it receives. Instead, the ADS Depositary will vote ALL the Shares it holds on deposit at the extraordinary general meeting as follows:

| • |  | if holders of at least 51% of the ADSs outstanding at the close of business in New York City on the ADS Record Date instruct the ADS Depositary to vote in the same manner regarding a resolution, the ADS Depositary will appoint the Voting Representative to vote ALL the Shares represented by the ADSs outstanding in the manner so instructed; and

| • |  | if the ADS Depositary does not receive instructions from holders of at least 51% of the ADSs outstanding at the close of business in New York City on the ADS Record Date to vote in the same manner regarding a resolution, the ADS Depositary itself will not provide any voting instruction and instead will appoint the Voting Representative to vote ALL the Shares represented by the ADSs outstanding as the Voting Representative deems appropriate, which may not be in your interest.

75

Alternatively, you may vote at the extraordinary general meeting if you cancel your ADSs by the close of business in New York City on , 2017 and become a holder of Shares by the close of business in Taiwan on the Share Record Date. If you hold your ADSs through a financial intermediary such as a broker, you must rely on the procedures of the financial intermediary through which you hold your ADSs if you wish to vote.

If you wish to cancel your ADSs, you need to make arrangements to deliver your ADSs to the ADS Depositary for cancellation together with (a) delivery instructions for the corresponding Shares (name and address of person who will be the registered holder of Shares) and (b) payment of the ADS cancellation fees (US$0.05 per ADS to be cancelled) and any applicable taxes. If you hold your ADSs in a brokerage, bank or nominee account, please contact your broker, bank or nominee to find out what actions you need to take to instruct the broker, bank or nominee to cancel the ADSs on your behalf. Upon cancellation of the ADSs, the ADS Depositary will arrange for JPMorgan Chase Bank, N.A., Taipei Branch, the custodian holding the Shares, to transfer registration of the Shares to the former ADS holder (or a person designated by the former ADS holder). In order to be a shareholder on the Share Record Date, you need to provide your ADSs and all applicable documentation and payments to the ADS Depositary by the close of business in New York City on , 2017. If after registration of Shares in your name you wish to receive a certificate evidencing the Shares registered in your name, you will need to request the registrar of the Shares to issue and mail a certificate to your attention.

If the ADS Depositary timely receives valid voting instructions from an ADS owner that fail to specify the manner in which the ADS Depositary is to vote the Shares represented by ADSs held by such ADS owner, such ADS owner is deemed to have instructed the ADS Depositary to vote in favor of the items set forth in the voting instructions.

As of the date hereof, the Company is not aware of any substantial opposition to any matter to be voted on at the extraordinary general meeting and does not believe that any such matter will have a material adverse impact on the rights of the Company’s shareholders.

Voting of Proxies and Failure to Vote

All Shares represented by valid proxies will be voted at the extraordinary general meeting in the manner specified by the holder. If a shareholder returns a properly signed proxy card but does not indicate how to vote, Shares represented by that proxy card will be voted FOR the proposal to approve the Share Exchange Agreement and the transactions contemplated by the Share Exchange Agreement, including the Share Purchase and FOR the proposal to authorize the Designated Persons to do all things necessary to give effect to the Share Exchange Agreement unless the shareholder appoints a person other than the chairman of the meeting as proxy, in which case the Shares represented by that proxy card will be voted (or not submitted for voting) as the proxy determines.

76

Brokers or other nominees who hold our Shares in “street name” for customers who are the beneficial owners of such Shares may not give a proxy to vote those customers’ Shares in the absence of specific instructions from those customers. Broker non-votes will be counted toward a quorum but will not be treated as voted at the extraordinary general meeting.

Revocability of Proxies

If you previously delivered a valid proxy to the Company, you may change your vote in one of two ways:

| • |  | first, you may attend the extraordinary general meeting and vote in person. Attendance, by itself, will not revoke a proxy. It will only be revoked if the shareholder files a written notice of revocation with the Company no later than two (2) days before the date of the extraordinary general meeting. Any written notice revoking a proxy should be sent to Siliconware Precision Industries Co., Ltd., No. 123, Sec. 3, Da Fong Road, Tantzu, Taichung, Taiwan, Republic of China, Attention: Eva Chen; or

| • |  | second, you may complete, date and submit a new proxy card, which shall include an explicit statement revoking the previous proxy and bear a later date than the proxy card sought to be revoked to the Company no later than five (5) days prior to the date of the extraordinary general meeting.

If you previously exercised your vote electronically, you may change your vote in one of three ways:

| • |  | first, you may attend the extraordinary general meeting and vote in person. Attendance, by itself, will not revoke an electronic vote. It will only be revoked if you withdraw your electronic vote through the Electronic Voting Platform no later than two (2) days before the date of the extraordinary general meeting;

| • |  | second, you may change your voting by logging into the Electronic Voting Platform no later than two (2) days prior to the date of the extraordinary general meeting; or

If a shareholder holds Shares through a broker and has instructed the broker to vote the shareholder’s Shares, the shareholder must follow directions received from the broker to change those instructions.

Holders of our ADSs may revoke their voting instructions by notification to the ADS Depositary in writing at any time prior to 12:00 p.m. (New York City time) on , 2017. A holder of ADSs can do this in one of two ways:

| • |  | first, a holder of ADSs can revoke its voting instruction by written notice of revocation timely delivered to the ADS Depositary; or

| • |  | second, a holder of ADSs can complete, date and submit a new ADS voting instruction card to the ADS Depositary bearing a later date than the ADS voting instruction card sought to be revoked to the ADS Depositary.

77

If you hold your ADSs through a broker, bank or nominee and you have instructed your broker, bank or nominee to give ADS voting instructions to the ADS Depositary, you must follow the directions of your broker, bank or nominee to change those instructions.

Rights of Shareholders Who Object to the Share Purchase

Shareholders who elect to dissent from the Share Purchase will have the right to seek appraisal and payment of the fair value of their Shares if the Share Purchase is completed, but only if they deliver to the Company, before or during the extraordinary general meeting at which the vote is taken, a written objection or an oral objection that has been put into record to the Share Purchase and subsequently comply with all procedures and requirements of Article 12 of the M&A Act for the exercise of appraisal rights, which is attached as Annex E to this proxy statement. The appraised fair value of your Shares as determined under that statute could be more than, the same as or less than the Share Purchase consideration you would receive pursuant to the Joint Share Exchange Agreement if you do not exercise appraisal rights with respect to your Shares.

ADS HOLDERS WILL NOT HAVE THE RIGHT TO SEEK APPRAISAL AND PAYMENT OF THE FAIR VALUE OF THE SHARES UNDERLYING THEIR ADSs. THE ADS DEPOSITARY WILL NOT ATTEMPT TO PERFECT ANY DISSENTERS’ RIGHTS WITH RESPECT TO ANY OF THE SHARES THAT IT HOLDS, EVEN IF AN ADS HOLDER REQUESTS THE ADS DEPOSITARY TO DO SO. ADS HOLDERS WISHING TO EXERCISE APPRAISAL RIGHTS MUST SURRENDER THEIR ADSs TO THE ADS DEPOSITARY, PAY THE ADS DEPOSITARY’S FEES REQUIRED FOR THE CANCELLATION OF THE ADSs AND PROVIDE INSTRUCTIONS FOR THE REGISTRATION OF THE CORRESPONDING SHARES BEFORE THE CLOSE OF BUSINESS IN NEW YORK CITY ON , 2017, AND BECOME HOLDERS OF SHARES BY THE CLOSE OF BUSINESS IN TAIWAN ON THE SHARE RECORD DATE. THEREAFTER, SUCH FORMER ADS HOLDERS MUST COMPLY WITH THE PROCEDURES AND REQUIREMENTS FOR EXERCISING APPRAISAL RIGHTS WITH RESPECT TO THE SHARES UNDER ARTICLE 12 OF THE ROC M&A ACT.

SUMMARY OF THE JOINT SHARE EXCHANGE AGREEMENT

The following section contains a summary of certain provisions of the Joint Share Exchange Agreement. The following summary is qualified in its entirety by reference to the Joint Share Exchange Agreement itself, which is incorporated herein by reference and included in this proxy statement as Annex A. We encourage you to read the Joint Share Exchange Agreement carefully and in its entirety, as it is the legal document governing the Share Purchase.

Structure of the Share Purchase

Pursuant to the Joint Share Exchange Agreement, all of the issued and outstanding shares of the Company and ASE will be transferred to a newly formed holding company, HoldCo, incorporated by ASE. HoldCo will issue new shares to ASE shareholders and pay the cash consideration to the Company’s shareholders, each as described below. At the Effective Time, the Company and ASE will become wholly owned subsidiaries of HoldCo, retaining their respective legal personalities, and the Company will cease to be a publicly traded company.

Directors and Officers of the Company

Upon completion of the Share Purchase, the directors of the Company will continue to serve as directors for their respective terms, and ASE has undertaken to reelect or appoint the directors whose terms end in June 2017, if they have not been found to violate their respective fiduciary duties. Mr. Lin, the Company’s chairman, and Mr. Chi-Wen Tsai, the Company’s president, are expected to serve as directors of the HoldCo. The directors of the Company are also authorized to retain the executive officers of the Company as long as the fiduciary duties of the directors can be discharged.

Consideration

At the Effective Time: (i) each issued Share immediately prior to the Effective Time (including the Company’s treasury shares), will automatically be transferred to HoldCo and converted into the right to receive the Original Per Share Consideration; and (ii) each ADS issued and outstanding immediately prior to the Effective Time, will be surrendered and converted into the right to receive the Original Per ADS Consideration.

In addition, at the Effective Time: (i) each issued ASE Share (including ASE’s treasury shares) immediately prior to the Effective Time, will be exchanged, in accordance with the exchange ratio, for 0.5 HoldCo Common Shares; and (ii) each ASE ADS issued and outstanding immediately prior to the Effective Time, will be surrendered in exchange for, in accordance with the exchange ratio, 1.25 HoldCo ADSs (following the Share Purchase, 1 HoldCo ADS will represent 2 HoldCo Common Shares, in contrast to the current ASE ADS, which represents 5 ASE Shares).

Treatment of Treasury Shares and Equity-Linked Securities

At the Effective Time, HoldCo shall become the successor to ASE under ASE’s US$200,000,000 Currency Linked Zero Coupon Convertible Bonds due 2018 (the “2015 CBs”) and US$400,000,000 Zero Coupon Convertible Bonds due 2018 (the “2013 CBs”, and together with the 2015 CBs, “ASE’s convertible bonds”) each pursuant to a supplemental indenture to be entered into among ASE, HoldCo and the trustee for such series of bonds. HoldCo shall assume all rights and obligations of ASE under ASE’s convertible bonds and holders of the 2015 CBs and the 2013 CBs to have the right convert each US$200,000,000 principal amount of such bond into approximately [●] and [●] shares of HoldCo, respectively. After the Effective time, ASE shall continue to serve as an obligor under ASE’s convertible bonds.

80

Treatment of the Bonds

If any of the Bonds have not been redeemed or repurchased by the Company and cancelled or converted by holders of the Bonds prior to the Effective Time, ASE and HoldCo jointly warrant to the Company that HoldCo, as co-obligors with the Company pursuant to a supplemental indenture to be entered into among the Company, HoldCo and the trustee of the Bonds, will pay the Final Per Share Consideration (subject to additional adjustments according to the terms of the Joint Share Exchange Agreement and applicable laws) to such holders of the Bonds for each Share they are entitled to receive if they exercise their conversion rights after the Effective Time.

Treatment of Fractional Shares

HoldCo will not issue any fractional shares of HoldCo Common Shares or HoldCo ADSs pursuant to the Share Purchase. Instead, ASE will aggregate the fractional entitlements and sell the aggregated ASE Shares using the closing price of ASE Shares on the TWSE on the trading day immediately preceding the Effective Time. Each holder of ASE Shares who otherwise would have received a fraction of a share of HoldCo Common Shares, will be entitled to receive, on a proportionate basis, the cash proceeds from the sale of such fractional shares.

Adjustments to the Consideration

The Original Per Share Consideration and the Original Per ADS Consideration will be adjusted if the Company issues any shares or cash dividends between the date of the Joint Share Exchange Agreement and the Effective Time, provided, that the cash consideration will not be so adjusted if the Company’s cash dividends in 2017, in aggregate, are less than 85% of the Company’s after-tax net profit for the year 2016.

ASE and the Company will negotiate changes to the cash consideration in good faith as a result of the occurrence of the events set forth below to the extent such events occur prior to the Effective Time and result in a reduction, individually or in aggregate, in the Company’s consolidated net book value by 10% or more compared to the Company’s net book value in its consolidated audited financial statements as of March 31, 2016 (excluding any such decrease resulting from dividends distributed by the Company):

| • |  | issuance of equity-linked securities by the Company (except for any Shares issued as a result of the exercise of conversion rights by the holders of the Bonds);

| • |  | disposal of material assets by the Company;

| • |  | occurrence of a major disaster causing a material adverse effect to the Company, material technical changes or other circumstances affecting the shareholders’ interests or the share price of Shares; and

If the Company receives a Superior Proposal from a third party the conditions of which, in the respective opinions of the Company’s audit committee and the Board, are more favorable than those of the Share Purchase, the Company will notify ASE in writing of such superior proposal and furnish ASE with details of the entire Superior Proposal. From the fifth business day following the delivery of such notice to ASE, the Company will be permitted to negotiate with, propose to, inquire with, deliberate with, contact, discuss with, offer to or consult with such third party.

DISSENTERS’ RIGHTS

The following is a brief summary of the rights of holders of the Shares to object to the Share Purchase and receive cash equal to the appraised fair value of their Shares, net of any applicable withholding taxes (“dissenters’ rights”). This summary is not a complete statement of the law, and is qualified in its entirety by the complete text of Article 12 of the ROC M&A Act, a copy of which is attached as Annex E to this proxy statement. If you are contemplating the possibility of objecting to the Share Purchase, you should carefully review the text of Annex E particularly the procedural steps required to perfect your dissenters’ rights. These procedures are complex and you should consult your Taiwan legal counsel. If you do not fully and precisely satisfy the procedural requirements of the ROC M&A Act, you will lose your dissenters’ rights.

Requirements for Exercising Dissenters’ Rights

Any registered holder of the Shares may object to the Share Purchase and request the Company to repurchase its, his or her Shares at the fair value of such Shares.

If you elect to exercise your dissenters’ rights, you will be precluded from exercising any other rights as a shareholder of the Company in connection with the Share Purchase, except for the right to participate fully in proceedings to determine the fair value of the Shares held by you and to seek relief on the grounds that the Share Purchase is void or unlawful. To exercise your dissenters’ rights, the following procedures must be followed:

| • |  | you must deliver a written objection or an oral objection that has been put into record to the Share Purchase and waive your voting right before or during the extraordinary general meeting;

| • |  | within 20 days immediately following the date on which the resolutions approving the Share Purchase are passed (the “Voting Date”), any dissenting shareholder who elects to dissent must deliver a written request to the Company, which shall specify the requested price for purchasing its, his or her Shares (the “Requested Repurchase Price”), and deposit the certificates of its, his or her Shares with an institution appointed by the Company and permitted by law to provided corporate action services;

| • |  | if the Company and a dissenting shareholder reach an agreement with respect to the repurchase price of such dissenting shareholder’s Shares, the Company will pay such agreed repurchase price to the dissenting shareholder within 90 days immediately following the Voting Date;

| • |  | if, within 60 days immediately following the Voting Date (the “Negotiation Period”), the Company fails to reach an agreement with respect to the repurchase price with any dissenting shareholder (the “Disputing Shareholder”), the Company shall, within 30 days immediately following the expiry of the Negotiation Period, file a petition with a competent court in the ROC for determination of the fair value of all the outstanding Dissenting Shares against all the Disputing Shareholders as the opposing parties. If the Company fails to file such petition, or such petition is voluntarily withdrawn by the Company or dismissed by the court, or the Company fails to list any Disputing Shareholder as the opposing party to such petition, the Company will be deemed as having agreed to the respective Requested Repurchase Price proposed by the relevant Disputing Shareholders. The Company shall bear all the costs of such proceeding;

93

| • |  | if, within 90 days immediately following the Voting Date, the Company fails to reach an agreement with respect to the repurchase price with any Disputing Shareholder, the Company shall pay for such Disputing Shareholder’s Shares at a price determined by the Company as the fair value of such Shares. If the Company fails to make such payment, it shall be deemed as agreeing to the Requested Repurchase Price proposed by such Disputing Shareholder; and

| • |  | before making a ruling on the fair price of the Shares (the “Appraised Price”), the court will allow the Company and the Disputing Shareholders to have a chance to present their positions in the court. After a final ruling is made, the Company shall, within 30 days thereafter, pay each Disputing Shareholder the Appraised Price for its, his or her Shares, deducting any previous payment and interest accrued (calculated based on a 5% annual rate) since the expiry of the 90-day period immediately following the Voting Date.

The provisions of Article 12 of the ROC M&A Act are technical and complex. If you fail to comply strictly with the procedures set forth in Article 12, you will lose your dissenters’ rights. You should consult your Taiwan legal counsel if you wish to exercise dissenters’ rights.

MATERIAL U.S. FEDERAL INCOME TAX CONSIDERATIONS

The following is a discussion of material U.S. federal income tax consequences to U.S. Holders (as defined below of the exchange of Shares or ADSs for cash pursuant to the Joint Share Exchange Agreement. This discussion only applies to U.S. Holders who hold their Shares or ADSs as capital assets for U.S. federal income tax purposes and does not describe all of the tax consequences that may be relevant in light of a U.S. Holder’s particular circumstances, including alternative minimum tax consequences and tax consequences applicable to U.S. Holders subject to special rules, such as:

| • |  | certain financial institutions;

| • |  | dealers or traders in securities or currencies;

| • |  | a regulated investment company;

| • |  | a real estate investment trust;

| • |  | an insurance company;

| • |  | a trader in securities that has elected the mark-to-market method of accounting for such securities;

| • |  | persons holding Shares or ADSs as part of a hedge, straddle, integrated transaction, or similar transaction;

| • |  | persons whose functional currency for U.S. federal income tax purposes is not the U.S. dollar;

99

| • |  | entities classified as partnerships or other pass-through entity for U.S. federal income tax purposes;

| • |  | tax-exempt entities, including “individual retirement accounts” or “Roth IRAs”;

| • |  | persons that own, or have owned, directly, indirectly or constructively, 10% or more of the total voting power of the Company;

| • |  | persons who received or acquired Shares or ADSs pursuant to the exercise of any employee stock option or otherwise as compensation;

| • |  | persons that continue to own after the Share Purchase, indirectly or constructively, shares of the Company; or

| • |  | persons holding Shares or ADSs in connection with a trade or business conducted outside the United States.

If an entity that is classified as a partnership for U.S. federal income tax purposes owns Shares or ADSs, the U.S. federal income tax treatment of a partner will generally depend on the status of the partner and the activities of the partnership. Partnerships owning Shares or ADSs and partners in such partnerships should consult their tax advisers as to the particular U.S. federal income tax consequences of the disposition of the Company’s Shares or ADSs.

This discussion is based on the U.S. Internal Revenue Code of 1986, as amended (the “Code”) administrative pronouncements, judicial decisions and final, temporary and proposed Treasury regulations, all as of the date hereof. These laws are subject to change, possibly with retroactive effect. U.S. Holders should consult their tax advisers to determine the particular U.S. federal income tax consequences to them of the transactions contemplated by the Joint Share Exchange Agreement, as well as the consequences under any applicable U.S. state, local and non-U.S. tax laws.

As used herein, the term “U.S. Holder” means a beneficial owner of Shares or ADSs that is, for U.S. federal income tax purposes:

| • |  | an individual citizen or resident of the United States;

| • |  | a corporation (or any other entity treated as a corporation for United States federal income tax purposes) created or organized in or under the laws of the United States, any state thereof or the District of Columbia;

| • |  | an estate, the income of which is subject to United States federal income taxation regardless of its source; or

| • |  | a trust if it (i) is subject to the primary supervision of a court within the United States and one or more United States persons have the authority to control all substantial decisions of the trust or (ii) has a valid election in effect under applicable United States Treasury regulations to be treated as a United States person.

This discussion does not contain a detailed description of all the United States federal income tax consequences to you in light of your particular circumstances or the effects of any state, local or non-United States tax laws. You are urged to consult your own tax advisor as to the particular tax consequences of the Share Purchase, including the effect of any federal, state, local, non-U.S. and other tax laws.

100

Exchange of Shares or ADSs for Cash. The exchange of the Company’s Shares or ADSs for cash will be a taxable transaction to a U.S. Holder for U.S. federal income tax purposes. Subject to the discussion in “—Passive Foreign Investment Company Rules” below, (i) an exchanging or dissenting U.S. Holder will generally recognize gain or loss on the disposition of Shares or ADSs equal to the difference between the amount of cash received and the U.S. Holder’s tax basis in the Shares or ADSs surrendered, and (ii) any gain or loss recognized will be capital gain or loss, and will be long-term capital gain or loss if the U.S. Holder has held the Shares or ADSs for more than one year.

Passive Foreign Investment Company Rules. In general, a non-U.S. corporation will be considered a “passive foreign investment company” or “PFIC” for any taxable year in which (i) 75% or more of its gross income consists of passive income (the “income test”) or (ii) 50% or more of the average quarterly value of its assets consists of assets that produce, or are held for the production of, passive income (the “asset test”). Passive income is any income that would be foreign personal holding company income under the Code, including, without limitation, dividends, interest, rents, royalties and capital gains. For purposes of the asset test, cash, cash equivalents, securities held for investment purposes and other similar assets are generally categorized as passive assets. If a non-U.S. corporation is a PFIC for any year during which a holder owns Shares or ADSs of that corporation, it generally will continue to be treated as a PFIC with respect to such holder for all succeeding years during which the holder holds the securities.

Based on the past and projected composition of our income and valuation of our assets, including goodwill, we do not believe we were a PFIC for our taxable year ended December 31, 2015 and we do not expect to become one in the current year, although there can be no assurance in this regard. As the determination of PFIC status requires extensive factual investigation, and because the Internal Revenue Service does not issue rulings with respect to PFIC status, there can be no assurance that we are not or will not become a PFIC. Accordingly, U.S. Holders are urged to consult their tax advisors with regard to the potential application of the tax consequences to them if we are a PFIC.

If we are a PFIC for the current taxable year, or was a PFIC during any prior year in which a U.S. Holder held Shares or ADSs and the U.S. Holder has not made a “deemed sale” election or mark-to-market election, any gain recognized by such U.S. Holder on the disposition of Shares or ADSs generally would be allocated ratably over such U.S. Holder’s holding period for the Shares or ADSs. The amount allocated to the taxable year of the disposition and to any year before we became a PFIC would be treated as ordinary income and could not be offset by any net operating losses. The amount allocated to each other taxable year would be subject to tax at the highest rate in effect for that year, and such amount would be increased by an additional tax equal to interest on the resulting tax deemed deferred with respect to such years. If we are a PFIC in a U.S. Holder’s taxable year of sale and a U.S. Holder has made a valid mark-to-market election with respect to its Shares or ADSs, any gain such U.S. Holder recognizes would be treated as ordinary income and any loss would be treated as ordinary loss, but only to the extent of the net amount previously included in income as a result of the mark-to-market election.

We did not and do not intend to provide the information U.S. Holders would need to make a qualified election fund election for the current taxable year, and as such the qualified election fund election has not been and will not be available to U.S. Holders.

Information Reporting and Backup Withholding. A U.S. Holder may be subject, under certain circumstances, to information reporting and backup withholding with respect to the amount of cash received in the Share Purchase. Under the backup withholding rules, a U.S. Holder may be subject to backup withholding unless the U.S. Holder is an exempt recipient and, when required, demonstrates this fact or provides a taxpayer identification number, makes certain certifications on IRS Form W-9, and otherwise complies with the applicable requirements. A U.S. Holder that does not provide its correct taxpayer identification number may also be subject to penalties imposed by the IRS.

101

Backup withholding is not an additional tax. Any amounts withheld under the backup withholding rules may be allowed as a refund or a credit against your U.S. Holder’s U.S. federal income tax liability provided the required information is furnished to the IRS.

Certain U.S. Holders who hold Shares or ADSs in physical form may be required to report the disposition of such Shares or ADSs on IRS Form 8938. Each U.S. Holder should consult its tax advisor concerning its reporting obligations with respect to a disposal of Shares or ADSs.

102

MATERIAL TAIWAN INCOME TAX CONSIDERATIONS

The following is a summary of material ROC tax consequences to the shareholders and ADS holders of the Company of the exchange of Shares or ADSs for cash pursuant to the Share Exchange Agreement.

For the purpose of this summary and/or the other relevant parts of this proxy statement, a “Non-ROC Holder” shall mean:

| • |  | an individual who is not an ROC citizen, who owns ADSs or Shares of the Company and who is not physically present in the ROC for 183 days or more during any calendar year; or

| • |  | a corporation or a non-corporate body that is organized under the laws of a jurisdiction other than the ROC for profit-making purposes and has no fixed place of business or other permanent establishment in the ROC.

The statements regarding ROC tax laws set forth below are based on the laws in force and applicable as of the date hereof, which are subject to change, possibly on a retroactive basis. This summary is not exhaustive of all tax considerations which may apply to a particular Non-ROC Holder and potential Non-ROC Holders are advised to consult their own tax advisors as to the overall tax consequences arising out of the Share Purchase.

Tax Consequences arising from the Share Purchase

Common shares

Capital gains

Capital gains obtained by Non-ROC Holders on transactions in the common shares are exempt from income tax.

Securities transaction tax

A securities transaction tax, at a rate of 0.3% of the sale proceeds, will be withheld upon a sale of common shares in the ROC.

ADSs

Capital gains

Capital gains obtained by holders of the ADSs arising out of a transaction such as the Share Purchase are not subject to ROC income tax. According to Article 8 of the Directions for Determination of ROC Sourced Income, adopted on September 3, 2009, any securities that are approved by competent ROC securities authorities and actually traded outside the ROC are outside the scope of ROC taxable income, and thus any income received by Non-ROC Holders from the sale of ADSs issued by ROC companies is not subject to ROC income tax.

Securities transaction tax

According to a letter issued by the ROC Ministry of Finance on March 23, 2010, no securities transaction tax will be imposed on transfer of the ADSs.

103

FUTURE SHAREHOLDER PROPOSALS

If the Share Purchase is completed, we will not have public shareholders and there will be no public participants in any future shareholders’ meeting. However, if the Share Purchase is not completed, an annual general meeting is expected to be held in [ ] 2017.

CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

Certain statements in this proxy statement, the documents attached hereto and the documents incorporated by reference in this proxy statement are forward-looking statements based on estimates and assumptions. These include statements as to such things as our financial condition, results of operations, plans, objectives, future performance and business, as well as forward-looking statements relating to the Share Purchase. Such forward-looking statements are based on facts and conditions as they exist at the time such statements are made. Forward-looking statements are also based on current expectations, estimates and projections about our business and the Share Purchase, the accurate prediction of which may be difficult and involve the assessment of events beyond our control. The forward-looking statements are further based on assumptions made by management. Forward-looking statements can be identified by forward-looking language, including words such as “believes,” “anticipates,” “expects,” “estimates,” “intends,” “may,” “plans,” “predicts,” “projects,” “will,” “would” and similar expressions, or the negative of these words. These statements are not guarantees of the underlying expectations or future performance and involve risks and uncertainties that are difficult to predict. Readers of this proxy statement are cautioned to consider these risks and uncertainties and not to place undue reliance on any forward-looking statements.

The following factors, among others, could cause actual results or matters related to the Share Purchase to differ materially from what is expressed or forecasted in the forward-looking statements:

| • |  | the satisfaction of the conditions to completion of the Share Purchase, including the approval of the Joint Share Exchange Agreement by our shareholders;

| • |  | the occurrence of any event, change or other circumstance that could give rise to the termination of the Joint Share Exchange Agreement;

| • |  | the cash position of the Company and its subsidiaries at the effective time;

| • |  | debt financing may not be funded at the effective time because of the failure of ASE to meet the closing conditions or for other reasons, which may result in the Share Purchase not being completed promptly or at all;

| • |  | the effect of the announcement or pendency of the Share Purchase on our business relationships, operating results and business generally;

| • |  | the risk that the Share Purchase may not be completed in a timely manner or at all, which may adversely affect our business and the prices of our Shares;

| • |  | the potential adverse effect on our business, properties and operations because of certain covenants we agreed to in the Joint Share Exchange Agreement;

| • |  | diversion of our management’s attention from our ongoing business operations;

104

| • |  | the amount of the costs, fees, expenses and charges related to the Share Purchase and the actual terms of the financings that will be obtained for the Share Purchase;

| • |  | the outcome of any legal proceedings, regulatory proceedings or enforcement matters that may be instituted against us and others relating to the Share Purchase; and

| • |  | other risks detailed in our filings with the SEC, including the information set forth under the caption “Item 3D. Risk Factors” in our Annual Report on Form 20-F for the year ended December 31, 2015. Please see “Where You Can Find More Information” beginning on page 106 for additional information.

Furthermore, the forward-looking statements do not reflect the potential impact of any future acquisitions, mergers, dispositions, joint ventures, collaborations, dividends or investments made by the parties. We believe that the assumptions on which our forward-looking statements are based are reasonable. However, many of the factors that will determine our future results are beyond our ability to control or predict and we cannot guarantee any future results, levels of activity, performance or achievements. We cannot assure you that the actual results or developments we anticipate will be realized or, if realized, that they will have the expected effects on our business or operations. In light of the significant uncertainties inherent in the forward-looking statements, readers should not place undue reliance on forward-looking statements, which speak only as of the date on which the statements were made and it should not be assumed that the statements remain accurate as of any future date. All subsequent written and oral forward-looking statements concerning the Share Purchase or other matters addressed in this proxy statement and attributable to us or any person acting on our behalf are expressly qualified in their entirety by the cautionary statements contained or referred to in this section. Further, forward-looking statements speak only as of the date they are made and, except as required by applicable law or regulation, we undertake no obligation to update these forward-looking statements to reflect future events or circumstances.

The Board of Directors

Siliconware Precision Industries Co., Ltd.

No. 123, Sec. 3, Da Fong Rd.

Tantzu, Taichung

Taiwan, Republic of China

Members of the Board of Directors:

You have requested our opinion as to the fairness, from a financial point of view, to the holders of common shares, par value NT$10 per share (the “Company Common Shares”), of Siliconware Precision Industries Co., Ltd. (the “Company”) of the consideration to be paid to such holders in the proposed share exchange (the “Transaction”) between the Company and a new holding company (“HoldCo”) to be established by Advanced Semiconductor Engineering, Inc. (“ASE”). Pursuant to the Joint Share Exchange Agreement, draft dated June 30, 2016 (the “Agreement”) between the Company and ASE, the Company will become a wholly-owned subsidiary of HoldCo and each outstanding Company Common Share, including the Company Common Shares represented by American Depositary Shares (“Company ADSs”) (each Company ADS representing five Company Common Shares) will be exchanged for the right to receive NT$51.20 per share in cash (the “Consideration”). Pursuant to the Agreement, ASE will also become a wholly-owned subsidiary of HoldCo and each outstanding common share, par value NT$10 per share, of ASE (the “ASE Common Shares”), including ASE Common Shares represented by American Depositary Shares, will be exchanged for the right to receive 0.5 common shares, par value NT$10 per share, of HoldCo.

In connection with preparing our opinion, we have (i) reviewed a draft dated June 30, 2016 of the Agreement; (ii) reviewed certain publicly available business and financial information concerning the Company and the industries in which it operates; (iii) compared the proposed financial terms of the Transaction with the publicly available financial terms of certain transactions involving companies we deemed relevant and the consideration paid for such companies; (iv) compared the financial and operating performance of the Company with publicly available information concerning certain other companies we deemed relevant and reviewed the current and historical market prices of the Company Common Shares and certain publicly traded securities of such other companies; (v) reviewed certain internal financial analyses and forecasts prepared by or at the direction of the management of the Company relating to its business; and (vi) performed such other financial studies and analyses and considered such other information as we deemed appropriate for the purposes of this opinion.

In addition, we have held discussions with certain members of the management of the Company with respect to certain aspects of the Transaction, and the past and current business operations of the Company, the financial condition and future prospects and operations of the Company, and certain other matters we believed necessary or appropriate to our inquiry.

In giving our opinion, we have relied upon and assumed the accuracy and completeness of all information that was publicly available or was furnished to or discussed with us by the Company or otherwise reviewed by or for us, and we have not independently verified (nor have we assumed responsibility or

B-1

liability for independently verifying) any such information or its accuracy or completeness. We have not conducted or been provided with any valuation or appraisal of any assets or liabilities, nor have we evaluated the solvency of the Company under any applicable laws relating to bankruptcy, insolvency or similar matters. In relying on financial analyses and forecasts provided to us or derived therefrom, we have assumed that they have been reasonably prepared based on assumptions reflecting the best currently available estimates and judgments by management as to the expected future results of operations and financial condition of the Company to which such analyses or forecasts relate. We express no view as to such analyses or forecasts or the assumptions on which they were based. We have also assumed that the Transaction and the other transactions contemplated by the Agreement will be consummated as described in the Agreement, and that the definitive Agreement will not differ in any material respects from the draft thereof furnished to us. We have also assumed that the representations and warranties made by the Company and ASE in the Agreement and the related agreements are and will be true and correct in all respects material to our analysis. We are not legal, regulatory or tax experts and have relied on the assessments made by advisors to the Company with respect to such issues.

Expert’s Opinion on the Fairness of the Share Price

To the audit committee of Siliconware Precision Industries Co., Ltd.

In accordance with Article 6 of the Business Mergers and Acquisitions Act, Siliconware Precision Industries Co., Ltd. (“SPIL”) engaged me to issue an opinion on the reasonableness of the consideration pursuant to an acquisition (“Acquisition”) of SPIL’s shares (the “Shares”) by Advanced Semiconductor Engineering Inc. (“ASE”).

I have completed the evaluation of the fair market price per Share as of May 25, 2016 (the “Valuation Base Date”). The evaluation process was conducted based on the Statements of Valuation Standards published by the Accounting Research and Development Foundation of the Republic of China.

SPIL engaged me to issue this opinion in respect of the fairness of the per Share consideration pursuant to the Acquisition. The fair price per Share and the content of this opinion will be significantly impacted by the purpose of the evaluation, the base and assumption of the evaluation and the date of the evaluation.

Based on the analysis, assumptions and limitations set forth in this opinion and by adopting the market-based approach (using the market price method, the price-earnings ratio (“P/E Ratio”) method and the price-book ratio (“P/B Ratio”) method with control premium adjustment, the reasonable price range per Share should be between NT$40.45 and NT$58.98.

Therefore, I am in an opinion that the consideration of NT$55 per Share pursuant to the Acquisition falls into the reasonable price range per Share and is fair and reasonable.

I. | Purpose of the Engagement

A. | Purpose of the Valuation

I was engaged by SPIL to evaluate the fair market price per Share as of the Valuation Base Date.

B. | Premise of Value

The premise of value is an assumption made for the transaction situation that mostly likely to happen, such as an assumption of on-going operation or an assumption of liquidation. Such assumption is the premise of determining the value of the subject to be evaluated. The premise of value for the purpose of this opinion is the going concern value.

C. | Standard of value

The standard of value for the purpose of this opinion is the fair market value. According to Annex II of the Standards of Valuation Process (Statements of Valuation Standards No. 4 published by the Accounting Research and Development Foundation), “fair market value” means the price for asset exchange or debt liquidation in cash or cash equivalent agreed by non-specific market participants with the willingness and ability to complete the transaction, informed by the related facts and without being enforced, in an open and unrestricted market through transactions in ordinary course.

D. | Assumption and Limitation

The conclusion in respect to the fair value of SPIL’s shares is only effective as of the Evaluation Base Date and for the purpose stated in this opinion.

In the process of evaluation, all the financial statements and other information provided by SPIL or its representatives, unless otherwise explicitly stated, are deemed as sufficiently reflecting the operation condition and results of SPIL during the applicable periods after due verification.

IV. | Evaluation Methods

According to the Standards of Valuation Process (Statements of Valuation Standards No. 4), the following three methods are normally used for companies and equity interests valuation.

A. Market-Based Approach. Market-based approach uses the transaction value of comparable companies as the base, taking into account the difference between the target company and the comparable companies and determine the valuation by applying an appropriate multiplier. Commonly used valuation methods adopting a market-based approach include:

| 1. | Comparable listed companies analysis, which compares the market price per share of the companies with the same or similar business operations to determine the valuation multiplier. Such analysis is commonly used for company or equity interest valuation.

| 2. | Comparable transactions analysis, which compares transaction values of similar transactions or the past transactions of the target company to determine the valuation multiplier. This analysis is commonly used for company, equity interest or individual asset or liability valuation.

Price to sales (P/S) ratio is commonly used to evaluate companies with a negative net asset value or a negative income or brand value. Because SPIL does not belong to the above category, the P/E Ratio and P/B Ratio through comparable listed companies analysis are used as the valuation multiplier. In addition, because SPIL is a publicly-listed company and its trading price on the stock market is available, I also used the market price method (by comparing the past trading price of the Shares) to evaluate the fair market value per Share.

C1-4

B. Income-Based Approach. Income-based approach uses the estimates of the future cash flow and discounts such estimates to their present value by discounted cash flow or capitalization analysis. Due to the multiple assumptions involved in the income-based approach and the high uncertainty of the estimates of the future cash flow, the income-based approach is not used for the purpose of this opinion.

C. Asset-Based Approach. This approach evaluates the total value of the individual assets and liabilities covered by the target company to reflect the total value of the target company and the equity interest. This approach estimates the consideration for reorganizing or acquiring the evaluation target based on the premise of on-going operation. Only if the evaluation is not using on-going operation as the premise, the liquidation value of the target company or the equity interest should be evaluated.

Asset-based approach should be based on the balance sheet of the target company and takes into consideration the assets and liabilities outside the balance sheet to evaluate the total value of the target company or equity interest.

Asset-based approach is commonly used to evaluate companies with large amount of assets and high fluctuation of revenues or holding companies. Because SPIL does not belong to the above category, asset-based approach is not used for the purpose of this opinion.

V. | Value Calculation

A. | Market Price Method

As SPIL is a publicly-listed company and its trading price on the stock market is available, the market price method is used to evaluate the fair market price per Share. The average market closing prices for 30, 60 and 90 business days up to, and including, May 25, 2016, is set forth in the following table.

|  |  | Unit : NT$ |
Item |  | Average Market Closing Price |
30-Day Average Closing Price |  |  | 47.93 |
60-Day Average Closing Price |  |  | 49.18 |
90-Day Average Closing Price |  |  | 50.04 |

Information Source: Average market closing price obtained from the TWSE.

B. | Comparable Companies Analysis

This opinion uses the P/E Ratio method and P/B Ratio method to estimate the fair market value per Share. The average P/E Ratios and P/B Ratios of the comparable companies are calculated based on the information obtained from the TWSE and the Taipei Exchange as of the Valuation Base Date.

Stock No. |  | Comparable Companies |  | P/E ratio |  |  | P/B ratio |
2311 |  | ASE |  |  | 13.17 |  |  |  | 1.60 |
6239 |  | PTI |  |  | 12.53 |  |  |  | 1.51 |
8150 |  | CMOS |  |  | 15.33 |  |  |  | 1.51 |
2449 |  | KYEC |  |  | 14.31 |  |  |  | 1.43 |
Average ratio of comparable companies (A) |  |  | 13.84 |  |  |  | 1.51 |
Earnings per Share/Net book value per Share (B) |  |  | 2.48 |  |  |  | 23.23 |
Fair market value per share (C=A*B) |  |  | 34.32 |  |  |  | 35.08 |

C1-5

Note 1: The source of information in the above table is TWSE and Taipei Exchange.

Note 2: Earnings per Share are calculated for the four quarters ended March 31, 2016; the net book value per Share is calculated as of March 31, 2016.

Based on the market price method, the P/E method and the P/B method as set forth above, the reasonable range of the fair market value per Share is set forth in the following table:

Valuation Method |  | FMV per Share |  |  | Range of FMV per Share prior to control premium adjustment
Market Value Method |  |  | 47.93~50.04 |  |  | 34.32~50.04
P/E Ratio Method |  |  | 34.32 |  |
P/B Ratio Method |  |  | 35.08 |  |

VI. | Valuation Adjustment

In an open market, normally, the fair market value of the shares only reflects the value of the shares held by minority shareholders. If the investment is to obtain control of the target company, the control premium needs to be taken into account. According to statistics for listed companies being merged or acquired, the average overall control premium is at a rate of 17.87%. Therefore, for the purpose of this opinion, I used 17.87% as the control premium rate and the adjusted range of the fair market value per share is set forth in the following table:

Valuation Method |  | FMV per Share |  |  | Range of FMV per Share after control premium adjustment
Market Value Method |  |  | 56.50~58.98 |  |  | 40.45~58.98
P/E Ratio Method |  |  | 40.45 |  |
P/B Ratio Method |  |  | 41.35 |  |

VII. | Conclusion

In view of the above, based on the market value method, price-book ratio method and price-earnings ratio method and taking into account of the control premium adjustment, I am in an opinion that if fair market value per Share as of the Valuation Base Date falls into the range of NT$40.45 to NT$58.98 per Share, then such fair market value is reasonable and fair.

Because SPIL does not belong to the above category, the P/E Ratio and P/B Ratio through comparable listed companies analysis are used as the valuation multiplier.

Due to the multiple assumptions involved in the income-based approach and the high uncertainty of the estimates of the future cash flow, the income-based approach is not used for the purpose of this opinion.

C2-4

C. Asset-Based Approach. This approach evaluates the total value of the individual assets and liabilities covered by the target company to reflect the total value of the target company and the equity interest. This approach estimates the consideration for reorganizing or acquiring the evaluation target based on the premise of on-going operation. Only if the evaluation is not using on-going operation as the premise, the liquidation value of the target company or the equity interest should be evaluated.

Asset-based approach should be based on the balance sheet of the target company and takes into consideration the assets and liabilities outside the balance sheet to evaluate the total value of the target company or equity interest.

Asset-based approach is commonly used to evaluate companies with large amount of assets and high fluctuation of revenues or holding companies. Because SPIL does not belong to the above category, asset-based approach is not used for the purpose of this opinion.

V. | Value Calculation

A. | Market Price Method

As SPIL is a publicly-listed company and its trading price on the stock market is available, the market price method is used to evaluate the fair market price per Share. The average market closing prices for 30, 60 and 90 business days up to, and including, June 29, 2016, is set forth in the following table.

|  | Unit : NT$ |
Item |  | Average Market Closing Price |
30-Day Average Closing Price |  |  | 51.23 |
60-Day Average Closing Price |  |  | 49.94 |
90-Day Average Closing Price |  |  | 50.14 |

Information Source: Average market closing price obtained from the TWSE.

B. | Comparable Companies Analysis

This opinion uses the P/E Ratio method and P/B Ratio method to estimate the fair market value per Share. The average P/E Ratios and P/B Ratios of the comparable companies are calculated based on the information obtained from the TWSE and the Taipei Exchange as of the Valuation Base Date.

Stock No. |  | Comparable Companies |  | P/E ratio |  |  | P/B ratio |
2311 |  | ASE |  |  | 14.28 |  |  |  | 1.72 |
6239 |  | PTI |  |  | 13.75 |  |  |  | 1.67 |
8150 |  | CMOS |  |  | 16.06 |  |  |  | 1.58 |
2449 |  | KYEC |  |  | 14.48 |  |  |  | 1.46 |
Average ratio of comparable companies (A) |  |  | 14.64 |  |  |  | 1.61 |
Earnings per Share/Net book value per Share (B) |  |  | 2.48 |  |  |  | 23.23 |
Fair market value per share (C=A*B) |  |  | 36.31 |  |  |  | 37.40 |

Note 1: The source of information in the above table is TWSE and Taipei Exchange.

Note 2: Earnings per Share are calculated for the four quarters ended March 31, 2016; the net book value per Share is calculated as of March 31, 2016.

C2-5

Based on the market price method, the P/E method and the P/B method as set forth above, the reasonable range of the fair market value per Share is set forth in the following table:

Valuation Method |  | FMV per Share |  |  | Range of FMV per Share prior to control premium adjustment
Market Value Method |  |  | 49.94~51.23 |  |  | 36.31~51.23
P/E Ratio Method |  |  | 36.31 |  |
P/B Ratio Method |  |  | 37.40 |  |

VI. | Valuation Adjustment

In an open market, normally, the fair market value of the shares only reflects the value of the shares held by minority shareholders. If the investment is to obtain control of the target company, the control premium needs to be taken into account. According to statistics for listed companies being merged or acquired, the average overall control premium is at a rate of 17.87%. Therefore, for the purpose of this opinion, I used 17.87% as the control premium rate and the adjusted range of the fair market value per share is set forth in the following table:

Valuation Method |  | FMV per Share |  |  | Range of FMV per Share after control premium adjustment
Market Value Method |  |  | 58.86~60.38 |  |  | 42.80~60.38
P/E Ratio Method |  |  | 42.80 |  |
P/B Ratio Method |  |  | 44.08 |  |

VII. | Conclusion

In view of the above, based on the market value method, price-book ratio method and price-earnings ratio method and taking into account of the control premium adjustment, I am in an opinion that if fair market value per Share as of the Valuation Base Date falls into the range of NT$42.80 to NT$60.38 per Share, then such fair market value is reasonable and fair.

ANNEX D-1: OPINION ISSUED BY MR. JI-SHENG CHIU AS ASE’S INDEPENDENT EXPERT,

DATED MAY 25, 2016 (ENGLISH TRANSLATION)

Independent Expert Opinion

on the Fairness of the Consideration for Joint Share Exchange in the Joint Share Exchange

Memorandum of Understanding between Advanced Semiconductor Engineering, Inc. and

Siliconware Precision Industries Co., Ltd.

I. | Introduction

Both Advanced Semiconductor Engineering Inc. (“ASE”) and Siliconware Precision Industries Co., Ltd. (“SPIL”) are the world’s leading companies in semiconductor packaging and testing sector. ASE and SPIL intend to enter into the Joint Share Exchange Memorandum of Understanding (“MOU”) to newly establish an investment holding company (“HoldCo”) by joint share exchange whereby both ASE and SPIL will become wholly-owned subsidiaries of HoldCo, in order to pursue their operating scale and improve their overall operating performance while taking into account of the flexibility and efficiency of their individual independent operations (“Share Exchange”). The Share Exchange will result in the exchange of all of ASE common shares in consideration for newly issued common shares of HoldCo, at an exchange ratio of each ASE common share for 0.5 HoldCo common share. Furthermore, the Share Exchange will result in the exchange of each of SPIL’s issued and outstanding shares for NT$55 in cash payable by HoldCo. The fairness of the consideration for Share Exchange under MOU is described and evaluated as below.

II. | Financial Position

Financial position of ASE and SPIL for the last two years and the first quarter of 2016 are summarized as below:

III. | Sources of Information

| (1) | Audited financial statements of ASE and SPIL for the years of 2014 and 2015 and reviewed financial statements for the first quarter of 2016.

| (2) | Business overviews, financial statements and other important information for evaluation purposes regarding ASE, SPIL and their peers obtained from Market Observation Post System.

| (3) | Information from website of the Taiwan Stock Exchange, website of the Taipei Exchange (GreTai Securities Market), Taiwan Economic Journal (TEJ) Database and Bloomberg’s complied comparison, analysis and historical stock price data of ASE, SPIL and their peers.

| (4) | Information on the industry and peers of ASE and SPIL.

IV. | Consideration for Share Exchange and Fairness thereof

The consideration for Share Exchange will be at an exchange ratio of each ASE common share for 0.5 HoldCo common share and each of SPIL’s issued and outstanding shares for NT$55 in cash payable by HoldCo. After the completion of the Share Exchange, both ASE and SPIL will become wholly-owned subsidiaries of HoldCo. The fairness of consideration for Share Exchange in respect of each of ASE and SPIL is described and evaluated as below:

| (A) | ASE

| 1. | ASE shareholders will contribute all the common shares held by them in ASE as of the share exchange record date in consideration of issue of their subscribed common shares required for the establishment of HoldCo. Following consummation of the Share Exchange, ASE will become a wholly-owned subsidiary of HoldCo, and previous ASE shareholders will become HoldCo shareholders. As such, similar to SPIL’s cash consideration of NT$55, ASE will become a wholly-owned subsidiary of HoldCo by exchange of the shares of one single company; theoretically, the rights of previous ASE shareholders will not be affected by the exact Share Exchange ratio.

| 2. | According to ASE’s reviewed consolidated financial statements as of March 31, 2016, its equity attributable to owners of parent amounted to NT$158,016,614,000; based on the latest update from the Commerce and Industry Registration Enquiry System of Department of Commerce, Ministry of Economic Affairs, ASE had a total of 7,918,272,896 issued and outstanding common shares as of April 26, 2016. Therefore, its net book value per common share was NT$19.956. Each ASE common share will be exchanged for 0.5 HoldCo common share resulting in 3,959,136,448 HoldCo common shares as of the share exchange record date. In addition, the net book value per common share as calculated based on ASE’s equity attributable to owners of parent to be assumed by HoldCo will be increased in the ratio of 1:0.5. Based on ASE’s equity attributable to owners of parent as of March 31, 2016, HoldCo’s net book value per common share would be NT$39.912 per share. For HoldCo common shareholders after the Share Exchange, the shareholders’ equity will not be impaired in any way by the Share Exchange ratio.

D1-2

| 3. | Net value of ASE’s equity attributable to owners of parent as of the share exchange record date may vary from that as of March 31, 2016. However, ASE shareholders will contribute all the common shares held by them in ASE as of the share exchange record date in consideration of and exchange for the common shares required for the establishment of HoldCo. As such, for HoldCo common shareholders after the Share Exchange, the shareholders’ equity will not be affected as a result of the Share Exchange.

In summary, it shall be fair and reasonable for all of ASE’s issued and outstanding shares to be exchanged for and in consideration of newly issued common shares of HoldCo at an exchange ratio of each ASE common share for 0.5 HoldCo common share resulting in ASE to become a wholly-owned subsidiary of HoldCo.

| (B) | SPIL

1. Methodologies Used

There are many methods for evaluating stock value. In practice, common methods include: market approach, such as market price approach (focusing on listed target companies; the fair value can be estimated by market price on the stock exchange) and market comparison approach (based on financial information of target companies and their peers in the market, using market multiplier such as price-earnings ratio, price-book ratio for analysis and evaluation); income approach; and cost approach.

Among these methods, income approach requires the Company’s estimates of future cash flow, involving multiple assumptions and having a higher uncertainty. Given its less objective nature compared to other methods, this method is not used. Cost approach examines and weighs SPIL’s business model and capital structure. Therefore, it is not appropriate for valuation and also not used. As such, we intend to use the market approach as primary evaluation method while taking into account of other non-quantitative factors, to evaluate the reasonable consideration of the Share Exchange for SPIL.

2. Selection of Peers

Based on customer attributes, business activities and business model, ChipMOS Technologies (Bermuda) Ltd. (“ChipMOS”), Chipbond Technology Corporation (“Chipbond”) and Powertech Technology Inc. (“Powertech”) are selected as peers. The following table lists the financial conditions of these 3 peers for the first quarter of 2016:

|  | Peers |
Items |  | ChipMOS (8150) |  |  | Chipbond (6147) |  |  | Powertech (6239) |

Note 2: | Earnings per share are estimated for the four quarters ended the first quarter of 2016 based on the net profit attributable to owners of parent in the respective peer’s consolidated financial statements for the year 2015 and the first quarter of 2016, number of common shares obtained from the Commerce and Industry Registration Enquiry System of Department of Commerce, Ministry of Economic Affairs and other financial data.

3. Valuation

| (1) | Market Price Approach

As SPIL is a listed company with its open market trading prices available for objective reference, this opinion sampled its recent publicly traded prices to evaluate the average closing prices for 60, 90 and 180 business days up to and including the valuation date of May 25, 2016 as follows:

Item |  | Average closing price |  |  | Theoretical price range |
|  | NT$ |
Latest 60 business days |  |  | 49.18 |  |  |  | 47.13 ~ 50.04 |
Latest 90 business days |  |  | 50.04 |  |
Latest 180 business days |  |  | 47.13 |  |

Note: | Sources of ex-rights/ex-dividend adjusted closing prices are from compilations of Taiwan Economic Journal (8/28/2015~5/25/2016); all average prices are calculated by simple arithmetic averaging of ex-rights/ex-dividend adjusted closing prices.

| (2) | Price-book Ratio Approach

The reasonable value per share of SPIL is estimated by calculating the net book value per share based on the financial information of SPIL and sampling the average price-book ratios of publicly traded peers - ChipMOS, Chipbond and Powertech for comparison purposes. The price-book ratios of publicly traded peers are calculated using their closing prices for 180 business days up to and including the valuation date of May 25, 2016 for sampling purposes and based on the total equity attributable to owners of parent in the respective peer’s consolidated financial statements for the first quarter of 2016, the number of common shares for respective peer obtained from the Commerce and Industry Registration Enquiry System of Department of Commerce, Ministry of Economic Affairs and other financial data. The reasonable reference price of SPIL is imputed as follows:

Comparable peers |  | Average closing price for latest 180 business days |  |  | Net value per share for the first quarter of 2016 |  |  | Price-book ratio |
|  | NT$ |
ChipMOS |  |  | 32.53 |  |  |  | 21.20 |  |  |  | 1.53 |
Chipbond |  |  | 47.86 |  |  |  | 36.31 |  |  |  | 1.32 |
Powertech |  |  | 66.98 |  |  |  | 44.48 |  |  |  | 1.51 |

Note: | Sources of ex-rights/ex-dividend adjusted closing prices are from compilations of Taiwan Economic Journal (8/28/2015~5/25/2016); all average prices are calculated by simple arithmetic averaging of ex-rights/ex-dividend adjusted closing prices.

D1-4

Item |  | Description
|  | NT$
Range of multipliers |  | 1.32 ~ 1.53
Net value per share of SPIL for the first quarter of 2016 |  | 23.23
Theoretical price range |  | 30.66 ~ 35.54

| (3) | Price-earnings Ratio Approach

The reasonable value per share of SPIL is estimated by calculating the earnings per share based on the financial information of SPIL and sampling the average price-book ratios of publicly traded peers - ChipMOS, Chipbond and Powertech for comparison purposes. Earnings per share for the four quarters ended the first quarter of 2016 are estimated, and thereby the average price-earnings ratios of publicly traded peers are calculated, using their closing prices for 180 business days up to and including the valuation date of May 25, 2016 for sampling purposes and based on the net profits attributable to owners of parent in the respective peer’s consolidated financial statements for 2015 and the first quarter of 2016, the number of common shares for respective peer obtained from the Commerce and Industry Registration Enquiry System of Department of Commerce, Ministry of Economic Affairs and other financial data. The reasonable reference price of SPIL is imputed as follows:

Comparable peers |  | Average closing price for latest 180 business days |  |  | Earnings per share in last four quarters |  |  | Price-earnings ratio |
|  | NT$ |
ChipMOS |  |  | 32.53 |  |  |  | 2.09 |  |  |  | 15.56 |
Chipbond |  |  | 47.86 |  |  |  | 2.64 |  |  |  | 18.13 |
Powertech |  |  | 66.98 |  |  |  | 5.37 |  |  |  | 12.47 |

Note: | Sources of ex-rights/ex-dividend adjusted closing prices are from compilations of Taiwan Economic Journal (8/28/2015~5/25/2016); all average prices are calculated by simple arithmetic averaging of ex-rights/ex-dividend adjusted closing prices.

Item |  | Description
|  | NT$
Range of multipliers |  | 12.47 ~ 18.13
Consolidated earnings per share of SPIL |  | 2.49
Theoretical price range |  | 31.05 ~ 45.14

| (4) | Conclusion

Calculation results of value of common shares under the foregoing evaluation methods are summarized as below. The above three methods have their theoretical and practical basis. Therefore, for avoidance of biases in the evaluation process, the imputation used 33.3% for purposes of weighted averaging by taking into account of other non-quantitative key factors with reference to the statistics of Bloomberg and the average premium rate of 33.24% of the global merger and acquisition cases in semiconductor industry since the third quarter of 2015. On these basis, the reasonable price range per share of SPIL shall be from NT$48.34 to NT$58.05. As such, we are of opinion that it shall be fair and reasonable for each SPIL common share in exchange of NT$55 in cash.

Evaluation method |  | Reference price range per share |  |  | Weight |  |  | Theoretical price range per share |  |  | Reference price range after adjustment |
|  | NT$ |
Market Price Approach |  |  | 47.13~50.04 |  |  |  | 33.3 | % |  |  | 36.28~43.57 |  |  |  | 48.34~58.05 |
Price-book Ratio Approach |  |  | 30.66~35.54 |  |  |  | 33.3 | % |  |
Price-earnings Ratio Approach |  |  | 31.05~45.14 |  |  |  | 33.3 | % |  |

D1-5

V. | Conclusion

In summary, ASE and SPIL are proposed to become wholly-owned subsidiaries of HoldCo by the joint share exchange. In relation to the Share Exchange, I, as the accountant, am of the opinion that it shall be fair and reasonable for each ASE common share in exchange for 0.5 HoldCo common share and each SPIL common share in exchange of NT$55 in cash.

DATED JUNE 29, 2016 (ENGLISH TRANSLATION)

Independent Expert Opinion

on the Fairness of the Consideration for Joint Share Exchange in the Joint Share Exchange

Agreement between Advanced Semiconductor Engineering, Inc. and Siliconware Precision

Industries Co., Ltd.

I. | Introduction

Both Advanced Semiconductor Engineering Inc. (“ASE”) and Siliconware Precision Industries Co., Ltd. (“SPIL”) are the world’s leading companies in semiconductor packaging and testing sector. ASE and SPIL intend to enter into the Joint Share Exchange Agreement to newly establish ASE Industrial Holding Co., Ltd. (“HoldCo”) by joint share exchange whereby both ASE and SPIL will become wholly-owned subsidiaries of HoldCo, in order to pursue their operating scale and improve their overall operating performance while taking into account of the flexibility and efficiency of their individual independent operations (“Share Exchange”). The Share Exchange will result in the exchange of all of ASE common shares in consideration for newly issued common shares of HoldCo, at an exchange ratio of each ASE common share for 0.5 HoldCo common share. Furthermore, the Share Exchange will result in the exchange of each of SPIL’s issued and outstanding shares for NT$55 in cash payable by HoldCo (“Cash Consideration”). The Cash Consideration is adjusted to NT$51.2 after deduction of cash dividends distribution of NT$2.8 per share and capital reserve cash distribution of NT$1 per share as resolved at SPIL’s annual general shareholder’s meeting for 2016. The fairness of the consideration for the Share Exchange under the Share Exchange Agreement is described and evaluated as below.

III. | Sources of Information

| (1) | Audited financial statements of ASE and SPIL for the years of 2014 and 2015 and reviewed financial statements for the first quarter of 2016.

| (2) | Business overviews, financial statements and other important information for evaluation purposes regarding ASE, SPIL and their peers obtained from Market Observation Post System.

| (3) | Information from website of the Taiwan Stock Exchange, website of the Taipei Exchange (GreTai Securities Market), Commerce and Industry Registration Enquiry System of Department of Commerce, Ministry of Economic Affairs, Taiwan Economic Journal (TEJ) Database and Bloomberg’s complied comparison, analysis and historical stock price data of ASE, SPIL and their peers.

| (4) | Information on the industry and peers of ASE and SPIL.

IV. | Consideration for Share Exchange and Fairness thereof

The consideration for Share Exchange will be at an exchange ratio of each ASE common share for 0.5 HoldCo common share and each of SPIL’s issued and outstanding shares for Cash Consideration of NT$55 payable by HoldCo. The Cash Consideration is adjusted to NT$51.2 after deduction of cash dividends distribution of NT$2.8 per share and capital reserve cash distribution of NT$1 per share as resolved at SPIL’s annual general shareholder’s meeting for 2016. After the completion of the Share Exchange, both ASE and SPIL will become wholly-owned subsidiaries of HoldCo. The fairness of consideration for Share Exchange in respect of each of ASE and SPIL is described and evaluated as below:

| (A) | ASE

| 1. | ASE shareholders will contribute all the common shares held by them in ASE as of the share exchange record date in consideration of issue of their subscribed common shares required for the establishment of HoldCo. Following consummation of the Share Exchange, ASE will become a wholly-owned subsidiary of HoldCo, and previous ASE shareholders will become HoldCo shareholders. As such, similar to SPIL’s Cash Consideration, ASE will become a wholly-owned subsidiary of HoldCo by exchange of the shares of one single company; theoretically, the rights of previous ASE shareholders will not be affected by the exact Share Exchange ratio.

| 2. | According to ASE’s reviewed consolidated financial statements as of March 31, 2016, its equity attributable to owners of parent amounted to NT$158,016,614,000; based on the latest update from the Commerce and Industry Registration Enquiry System of Department of Commerce, Ministry of Economic Affairs, ASE had a total of 7,918,272,896 issued and outstanding common shares as of April 26, 2016. Therefore, its net book value per common share was NT$19.956. Each ASE common share will be exchanged for 0.5 HoldCo common share resulting in 3,959,136,448 HoldCo common shares as of the share exchange record date. In addition, the net book value per common share as calculated based on ASE’s equity attributable to owners of parent to be assumed by HoldCo will be increased in the ratio of 1:0.5. Based on ASE’s equity attributable to owners of parent as of March 31, 2016, HoldCo’s net book value per common share would be NT$39.912 per share. For HoldCo common shareholders after the Share Exchange, the shareholders’ equity will not be impaired in any way by the Share Exchange ratio.

D2-2

| 3. | Net value of ASE’s equity attributable to owners of parent as of the share exchange record date may vary from that as of March 31, 2016. However, ASE shareholders will contribute all the common shares held by them in ASE as of the share exchange record date in consideration of and exchange for the common shares required for the establishment of HoldCo. As such, for HoldCo common shareholders after the Share Exchange, the shareholders’ equity will not be affected as a result of the Share Exchange.

In summary, it shall be fair and reasonable for all of ASE’s issued and outstanding shares to be exchanged for and in consideration of newly issued common shares of HoldCo at an exchange ratio of each ASE common share for 0.5 HoldCo common share resulting in ASE to become a wholly-owned subsidiary of HoldCo.

| (B) | SPIL

| 1. | Methodologies Used

There are many methods for evaluating stock value. In practice, common methods include: market approach, such as market price approach (focusing on listed target companies; the fair value can be estimated by market price on the stock exchange) and market comparison approach (based on financial information of target companies and their peers in the market, using market multiplier such as price-earnings ratio, price-book ratio for analysis and evaluation); income approach; and cost approach.

Among these methods, income approach requires the Company’s estimates of future cash flow, involving multiple assumptions and having a higher uncertainty. Given its less objective nature compared to other methods, this method is not used. Cost approach examines and weighs SPIL’s business model and capital structure. Therefore, it is not appropriate for valuation and also not used. As such, we intend to use the market approach as primary evaluation method while taking into account of other non-quantitative factors, to evaluate the reasonable consideration of the Share Exchange for SPIL.

| 3. | Valuation

(1) Market Price Approach

As SPIL is a listed company with its open market trading prices available for objective reference, this opinion sampled its recent publicly traded prices to evaluate the average closing prices for 60, 90 and 180 business days up to and including the valuation date of June 29, 2016 as follows:

Item |  | Average closing price |  |  | Theoretical price range
|  | NT$
Latest 60 business days |  |  | 46.25 |  |  | 45.05 ~ 46.45
Latest 90 business days |  |  | 46.45 |  |
Latest 180 business days |  |  | 45.05 |  |

Note: | Sources of ex-rights/ex-dividend adjusted closing prices are from compilations of Taiwan Economic Journal (10/5/2015~6/29/2016); all average prices are calculated by simple arithmetic averaging of ex-rights/ex-dividend adjusted closing prices.

D2-4

(2) Price-book Ratio Approach

The reasonable value per share of SPIL is estimated by calculating the net book value per share based on the financial information of SPIL and sampling the average price-book ratios of publicly traded peers - ChipMOS, Chipbond and Powertech for comparison purposes. The price-book ratios of publicly traded peers are calculated using their closing prices for 180 business days up to and including the valuation date of June 29, 2016 for sampling purposes and based on the total equity attributable to owners of parent in the respective peer’s consolidated financial statements for the first quarter of 2016, the number of common shares for respective peer obtained from the Commerce and Industry Registration Enquiry System of Department of Commerce, Ministry of Economic Affairs and other financial data. The reasonable reference price of SPIL is imputed as follows:

Comparable peers |  | Average closing price for latest 180 business days |  |  | Net value per share for the first quarter of 2016 |  |  | Price- book ratio |
|  | NT$ |
ChipMOS |  |  | 32.53 |  |  |  | 21.20 |  |  |  | 1.53 |

Net value per share of SPIL for the first quarter of 2016 |  | 23.23
Theoretical price range |  | 29.97 ~ 35.54

(3) Price-earnings Ratio Approach

The reasonable value per share of SPIL is estimated by calculating the earnings per share based on the financial information of SPIL and sampling the average price-book ratios of publicly traded peers - ChipMOS, Chipbond and Powertech for comparison purposes. Earnings per share for the four quarters ended the first quarter of 2016 are estimated, and thereby the average price-earnings ratios of publicly traded peers are calculated, using their closing prices for 180 business days up to and including the valuation date of June 29, 2016 for sampling purposes and based on the net profits attributable to owners of parent in the respective peer’s consolidated financial statements for 2015 and the first quarter of 2016, the number of common shares for respective peer obtained from the Commerce and Industry Registration Enquiry System of Department of Commerce, Ministry of Economic Affairs and other financial data. The reasonable reference price of SPIL is imputed as follows:

Comparable peers |  | Average closing price for latest 180 business days |  |  | Earnings per share in last four quarters |  |  | Price- earnings ratio |
|  | NT$ |
ChipMOS |  |  | 32.53 |  |  |  | 2.09 |  |  |  | 15.56 |

(4) Summary

Calculation results of value of common shares under the foregoing evaluation methods are summarized as below. The above three methods have their theoretical and practical basis. Therefore, for avoidance of biases in the evaluation process, the imputation used 33.3% for purposes of weighted averaging by taking into account of other non-quantitative key factors with reference to the statistics of Bloomberg and the average premium rate of 33.86% of the global merger and acquisition cases in semiconductor industry since the third quarter of 2015. On these basis, the reasonable price range per share of SPIL shall be from NT$46.98 to NT$56.30. As such, we are of opinion that it shall be fair and reasonable for each SPIL common share in exchange of Cash Consideration of NT$55 (the Cash Consideration is adjusted to NT$51.2 after deduction of cash dividends distribution of NT$2.8 per share and capital reserve cash distribution of NT$1 per share as resolved at SPIL’s annual general shareholder’s meeting for 2016).

Evaluation method |  | Reference price range per share |  | Weight |  |  | Theoretical price range per share |  | Reference price range after adjustment
|  | NT$
Market Price Approach |  | 45.05~ 46.45 |  |  | 33.3 | % |  | 35.10~ 42.06 |  | 46.98~ 56.30
Price-book Ratio Approach |  | 29.97~35.54 |  |  | 33.3 | % |  |
Price-earnings Ratio Approach |  | 30.28~ 44.20 |  |  | 33.3 | % |  |

V. | Conclusion

In summary, ASE and SPIL are proposed to become wholly-owned subsidiaries of HoldCo by the joint share exchange. In relation to the Share Exchange, I, as the accountant, am of the opinion that it shall be fair and reasonable for each ASE common share in exchange for 0.5 HoldCo common share and each SPIL common share in exchange of Cash Consideration of NT$55 (the Cash Consideration is adjusted to NT$51.2 after deduction of cash dividends distribution of NT$2.8 per share and capital reserve cash distribution of NT$1 per share as resolved at SPIL’s annual general shareholder’s meeting for 2016).

ANNEX E: ROC BUSINESS MERGERS AND ACQUISITIONS ACT – ARTICLE 12

If the following event occurs when a company is undergoing a merger, consolidation, acquisition or division, a shareholder may request the company to repurchase her shares at the then fair price of such shares:

| 1. | In the event that the company is undergoing an acquisition as described in Article 27 of this Act, the shareholder delivers a written objection or an oral objection that has been put into record and waives her voting rights before or during the shareholders’ meeting;

Any shareholder who has made the request as provided in the preceding paragraph shall submit a written request that specifies the requested repurchase price and deposit the certificates of her shares within 20 days immediately following the date at which the shareholder resolutions are passed.

The company shall appoint an institution that is permitted by law to provide corporate action services to handle the shares deposited by the dissenting shareholder. The shareholder shall deposit her shares to such institution and the institution shall issue a certificate that specifies the type and amount of deposited shares to the shareholder; any deposit by book-entry transfer shall be governed by the procedures set forth in the rules and regulations in relation to the centralized securities depositary enterprises.

The request of a shareholder as provided in Paragraph 1 shall lose its effect when the company abandons its corporate action as provided in the same paragraph.

If the company and the shareholder reach an agreement with respect to the repurchase price, the company shall pay such repurchase price to the shareholder within 90 days immediately following date at which the shareholders resolutions are passed. If no agreement is reached, within 90 days immediately after the date at which the shareholders resolutions are passed, the company shall pay for the shareholder’s shares at a price determined by the company as the fair price for such shares; if the company fails to make such payment, the company shall be deemed as having agreed to the repurchase price requested by the shareholder pursuant to Paragraph 2.

If the company fails to reach an agreement with any shareholder with respect to the repurchase price within 60 days immediately following the date at which the shareholders’ resolutions are passed, the company shall, within 30 days after the expiry of the 60-day period, file a petition with a court for a ruling to determine the fair price of the shares against all the dissenting shareholders as the opposing parties. If the company fails to list any shareholder whom it has not reached an agreement with as an opposing party, or the petition is withdrawn by the company or dismissed by the court, the company shall be deemed as having agreed to the repurchase price requested by the shareholder pursuant to Paragraph 2. However, if the opposing party has already presented her position in the court or the court’s ruling has already been delivered to the opposing party, the company shall not withdraw the petition unless agreed by the opposing party.

When the company files a petition with the court for a ruling to determine the repurchase price, the company shall attach to the petition the audited and attested financial statements of the company and the fair price assessment report by the certified public accountants, and written copies and photocopies thereof according to the number of opposing parties for the court to distribute to each opposing party.

Before making a ruling with respect to the repurchase price, the court shall allow the company and the opposing parties to have the chance to present their positions. If there are two or more opposing parties, the provisions set out in Articles 41 to 44, as well as Paragraph 2 of Article 401 of ROC Civil Procedure Code shall apply mutatis mutandis.

E-1

If any party appeals against the ruling made pursuant to the preceding paragraph, the court shall allow the parties at dispute to have the chance to present their positions before making a decision on the appeal.

When the ruling with respect to the repurchase price becomes final and binding, the company shall, within 30 days immediately after the ruling becoming final and binding, pay such final repurchase price to the dissenting shareholders, deducting any previous payment and interest accrued since the expiry of the 90-day period immediately following the date at which shareholders resolutions are passed.

The provisions set forth in article 171 and paragraphs 1, 2 and 4 of article 182 of the ROC Non-Contentious Matters Act shall apply mutatis mutandis.

The company shall bear the expenses of the petition and the appraiser’s compensation.
