Filing Released Lang Actions
第二届监事会第九次会议决议公告
Regulatory Filings Classification · 95% confidence The document is a resolution announcement from the Supervisory Board of Hefei Xinhui Microelectronics Co., Ltd. It details the meeting held on April 29, 2025, including the approval of the 2025 Q1 report, employee stock ownership plans, and amendments to supervisory meeting rules. The document does not contain the actual financial report or detailed financial data but refers to the 2025 Q1 report being disclosed on the Shanghai Stock Exchange website. The document is a formal announcement of meeting resolutions and approvals rather than the report itself. Given the short length (1979 characters) and the nature of the content, this fits best under Regulatory Filings (RNS) as it is a regulatory announcement of supervisory board resolutions and approvals, not the full quarterly report or other detailed filings.
