The Insider Sale Details
United Microelectronics Corporation (UMC) CFO and Senior Vice President Liu Chitung completed an open-market sale of 1,900,000 shares on July 13, 2026, for a total transaction value of $294,291,000, with a Form 4 insider transaction filing submitted the same day. The sale represents 0.485% of UMC’s $60.7 billion current market capitalization, a large-scale executive transaction that stands apart from the company’s recent small-scale executive sales.
Cross-Referenced Signals
Per recent public Form 4 filings, on June 30, 2026, Vice President HU CHE-JEN sold just 10,000 shares for $1,713,000, a far smaller transaction than this one. The sale was executed at $154.89 per share, a notable difference from the current secondary market price of $24.34. Additionally, 2025 year-end 13F institutional holdings data shows UMC had 282 institutional holders (up 31 quarter-over-quarter), with aggregate institutional ownership of 6.1% of the float, including 61 new positions, 177 increased positions, 56 reduced positions, and 32 fully closed positions.
Signal Limits and Next Steps
This Form 4 filing only discloses transaction specifics, and does not confirm the personal motivation behind the sale, whether the trade was executed under a pre-arranged 10b5-1 plan (no explicit confirmation is provided in the available data), nor does it reflect a judgment on the company’s future valuation or performance outlook. Monitor for additional large-scale executive transaction filings, as well as UMC’s Q2 2026 earnings report scheduled for July 29, 2026.

本次内幕交易详情
联华电子(UMC)CFO兼高级副总裁刘池同于2026年7月13日完成190万股公开市场股票出售，交易总额达294,291,000美元，同日提交了Form 4内幕交易备案。该笔减持占UMC当前607亿美元总市值的0.485%，属于高管大额持仓变动，与公司近期其他小额高管交易形成显著区别。
横向对比信号
对比公司近期公开的Form 4备案记录，2026年6月30日副总裁HU CHE-JEN仅减持1万股，对应金额171.3万美元，交易规模远低于本次操作。本次减持的成交价格为每股154.89美元，与当前二级市场公开报价24.34美元存在明显差异。此外，2025年12月31日的13F机构持仓数据显示，UMC共有282家机构持有者，较上一季度增加31家，机构合计持仓占浮筹比例为6.1%，其中61家为新持仓、177家增持、56家减持、32家清仓。
信号局限与后续关注
本次Form 4备案仅披露交易细节，无法直接证明此次减持的个人动机、是否基于10b5-1预先安排交易计划，也不代表对公司未来估值或业绩前景的判断。后续需留意是否有更多高管层面的大额交易备案，以及公司2026年7月29日即将发布的2026年第二季度财报。
