TSE has designated the following issues as Securities Under Supervision (Examination).
1. Issue Name
| Issue Name (Stock) | Code | Market Segment |
|---|---|---|
| UMC Electronics Co.,Ltd. | 6615 | Prime Market |
| SUNWELS Co.,Ltd. | 9229 | Prime Market |
2. Period of Designation as Securities Under Supervision (Examination)
From Apr. 1, 2026 (Wed.) to the day when TSE determines whether the issues have fallen under the delisting criteria
3. Reason
Because the stock(s) on the list are not likely to meet the continued listing criteria within the improvement period and examination is being conducted in connection with a transfer of market segment
(Enforcement Rules for Securities Listing Regulations, Rule 604, Paragraph 1, Item (2))
Details of Reason
The company(ies) listed in "1. Issue Name" above did not meet the continued listing criteria as of the previous record date. Therefore, unless they meet said criteria within the improvement period, their stock(s) will be delisted. As of today, TSE cannot confirm said company(ies)' compliance with the continued listing criteria, and therefore considers it likely that their stock(s) will be delisted. In addition, as the company(ies) have filed an application for transfer of market segment and are currently undergoing examination by Japan Exchange Regulation, TSE hereby designates their stock(s) as Securities Under Supervision (Examination).
Please note that TSE will examine a listed company's compliance status with the continued listing criteria using the “Table of Distribution of Stocks, etc.” submitted by the company.
- ･If TSE confirms compliance with the continued listing criteria based on its examination of the “Distribution Status of Share Certificates, etc.” or approves a market segment transfer as a result of the segment transfer examination, the stock(s) will remain listed.
