Yamaichi Investment Co. plans to acquire shares in Powerchip Innovation Investment Holding, formerly Powerchip Technology, for up to NT$1 billion. The proposed price is NT$40 to NT$45 per share, according to an announcement issued through its appointed agent, Jen-Ming Attorneys-at-Law.
Applications will be accepted from Nov. 10 through Nov. 16, 2026. Shareholders who want to sell must state their own proposed price. Applications will be matched from the lowest price upward. If two applications carry the same price, the earlier submission will take priority. The process will continue until the total transaction value reaches NT$1 billion.
Purchase terms and order handling
Yamaichi Investment is a core holding company of the family of Powerchip founder Huang Chung-jen and the largest shareholder of Etron Technology. The company appointed lawyers to publish the purchase announcement on Nov. 6, setting the price range at NT$40 to NT$45 and the maximum planned investment at NT$1 billion.
If the accumulated applications reach the funding ceiling and the final eligible application exceeds the amount still available, Yamaichi may reduce the number of shares included in that transaction. The announcement also gives Yamaichi the right to conduct the final review and decide which applicants will become counterparties.
Submission window and delivery requirements
Shareholders wishing to sell must submit a “Share Sale Intention Form” to Jen-Ming Attorneys-at-Law between Nov. 10 and Nov. 16. The forms will be accepted during business hours, from 9:00 a.m. to 4:30 p.m. each day, either by delivery or fax.
The agent will use its receipt stamp or the fax machine record to determine the submission time. Late applications and documents that fail to meet the stated requirements will not be accepted. After the deadline, applications that pass the review will be transferred to the stock affairs agency department of Capital Securities for the next stage of processing.
Tax, share transfer and settlement
Capital Securities’ stock affairs agency department is expected to mail transfer documents to eligible shareholders by registered post on Nov. 20. Shareholders must complete the securities transaction tax payment and share-transfer procedures between Nov. 23 and Nov. 27.
Under the applicable rules, the seller will bear the securities transaction tax. The required process depends on whether the shares are held in a registration account or a brokerage account. Shareholders must prepare the tax payment receipt and relevant documents before visiting the stock affairs agency department or their original broker to complete the transfer.
Cash deposit and settlement timetable
To support its performance obligations, Yamaichi has committed to depositing more than NT$1 billion in cash into a dedicated account at CTBC Bank on Nov. 10, 2026. A lawyer will witness the account balance.
Once eligible shareholders have completed the tax payment and share-transfer procedures, Yamaichi expects to remit the purchase funds to the financial accounts designated by shareholders on Dec. 4, completing the settlement.
Powerchip control contest before the special meeting
The purchase comes after Huang Chung-jen, the founder of the Powerchip group, died in late July 2026. It also comes ahead of the company’s Nov. 25 special shareholders meeting, where all director and supervisor seats are scheduled for re-election.
The market faction led by Lin Wei-cheng, the convener of the Powerchip self-rescue group, has called on retail investors to raise more than NT$13.6 billion. Its plan is to purchase a 20% stake at NT$50 per share.
The company faction has filed a lawsuit in response, alleging that the plan violates tender-offer rules. It also issued an open letter to all shareholders, with the management team reporting its performance to 270,000 minority shareholders.
The company faction has pledged to amend the articles of incorporation at the special meeting to introduce independent directors and an audit committee. The proposed changes are intended to establish a governance foundation for Powerchip’s return to the emerging-stock market and the listed or OTC markets.
