Filing Released Lang Actions
北京盈科（厦门）律师事务所关于三达膜2025年年度股东会的法律意见书
Regulatory Filings Classification · 75% confidence The document is a “法律意见书” (Legal Opinion Letter) issued by a law firm regarding the legality of the procedures and vote counts at the company’s 2025 Annual General Meeting. It is a compliance/legal opinion submission rather than an actual annual report, proxy statement, earnings release or presentation. It does contain voting results, but as part of a legal opinion rather than a standalone voting‐results announcement. None of the highly specific categories (e.g., proxy solicitation, AGM slides, management discussion) precisely fit a standalone legal opinion letter. Thus, it falls into the fallback “Regulatory Filings” category (RNS).

2025年年度股东会决议公告
Declaration of Voting Results & Voting Rights Announcements Classification · 92% confidence The document is an official announcement of the resolutions (议案) voted on and passed at the company's 2025 Annual General Meeting (AGM), including detailed voting results for each proposal. This matches the definition of a Declaration of Voting Results & Voting Rights Announcements (DVA).

关于股东减持股份计划公告
Regulatory Filings Classification · 50% confidence The document is a regulatory announcement by 三达膜环境技术股份有限公司 detailing a planned reduction of holdings by a >5% shareholder and senior executives. It is not a financial report, proxy statement, dividend notice, or share issuance; nor is it the company buying back its own shares. This falls into the miscellaneous regulatory announcement category for filings that don’t neatly fit other types. Hence it is classified as a Regulatory Filing (RNS).

关于参加“2026年陕西辖区上市公司投资者集体接待日暨2025年度业绩说明会”的公告
Regulatory Filings Classification · 75% confidence The document is an announcement by 三达膜环境技术股份有限公司 about participating in a regional investor reception day and holding a 2025 annual performance briefing, inviting investors to submit questions. It contains no actual financial statements or presentation materials; it merely notifies investors of an upcoming event. This falls under general regulatory announcements and does not fit a more specific category such as an Annual Report, Earnings Release, or Investor Presentation itself. Therefore, it should be classified as a Regulatory Filing (RNS).
2026-05-11 Chinese
关于召开2025年度暨2026年第一季度业绩说明会的公告
Investor Presentation Classification · 85% confidence The document is a public notice announcing the time, venue, and format of the company’s performance explanation meeting (“业绩说明会”) for the full‐year 2025 results and Q1 2026. It does not contain any actual financial statements or detailed MD&A, nor is it the release of the annual or interim report itself; rather, it informs investors of an upcoming presentation/interactive session. This aligns with the definition of an Investor Presentation (IP).
2026-05-11 Chinese
关于持股5%以上股东减持股份结果公告
Major Shareholding Notification Classification · 100% confidence The document is an announcement regarding the results of a shareholding reduction by a shareholder holding more than 5% of the company's shares. It details the shareholder's name, shareholding before and after the reduction, the number of shares reduced, the reduction period, and compliance with regulations. This fits the definition of a Major Shareholding Notification (MRQ), which covers notifications of changes in significant share ownership levels crossing thresholds. The document is not a full financial report, earnings release, or other types of filings. Therefore, the correct classification is MRQ.
