Filing Released Lang Actions
董事会薪酬与考核委员会关于公司2026年限制性股票激励计划首次授予激励对象名单的核查意见（截止授予日）
Regulatory Filings Classification · 72% confidence The document is a formal announcement by the Board’s Remuneration and Appraisal Committee regarding the eligibility and approval of the initial grant list under a 2026 restricted stock incentive plan. It does not present financial statements or an earnings call transcript, nor is it an AGM presentation or a shareholder vote result. It is a routine regulatory disclosure about an equity incentive plan under Chinese securities rules, fitting the “Regulatory Filings” category (RNS) as a general compliance announcement rather than a direct capital issuance notice or a US-style remuneration proxy (DEF 14A).
2026-05-19 Chinese
第二届董事会第十六次会议决议公告
Board/Management Information Classification · 78% confidence The document is a corporate announcement of the resolutions passed at the company’s Second Board (Session 2) Sixteenth Meeting, detailing board meeting procedures, voting results, and approvals (e.g., exemption of notice period, stock incentive grant). This is neither a financial report nor a shareholder meeting vote, but rather a board meeting resolution announcement. This matches the Board/Management Information category (MANG).

上海市锦天城律师事务所关于胜科纳米（苏州）股份有限公司2026年限制性股票激励计划首次授予限制性股票之法律意见书
Regulatory Filings Classification · 32% confidence The document is a legal opinion letter issued by a law firm regarding the legality of a restricted stock incentive plan. It does not present financial statements, earnings data, management commentary, or an actual share issuance announcement. It is also not a U.S. proxy statement (DEF 14A), nor a full annual or interim report. Rather, it is a compliance/legal document provided for regulatory purposes. This does not neatly fit any other category, so it should be classified under the fallback Regulatory Filings (RNS).
2026-05-19 Chinese
华泰联合证券有限责任公司关于胜科纳米（苏州）股份有限公司2025年度持续督导跟踪报告
Regulatory Filings Classification · 90% confidence The document is a “持续督导跟踪报告” (continuous supervision follow-up report) prepared by the IPO sponsor (Huatai United Securities) for Shengke Nano, detailing issues found, risk analysis, financial indicators, use of IPO proceeds, shareholding changes, etc. It is a regulatory submission required by Chinese securities law following an initial public offering, not a standard annual or interim financial report, earnings release, or proxy/meeting material. It does not fit any more specific category, so it falls under the fallback “Regulatory Filings (RNS).”
2026-05-18 Chinese
上海市锦天城律师事务所关于胜科纳米（苏州）股份有限公司2025年年度股东会的法律意见书
Regulatory Filings Classification · 78% confidence The document is a legal opinion letter (“法律意见书”) issued by Allbright Law Offices regarding the 2025 annual shareholders’ meeting procedures, qualifications, and vote validity of Shengke Nano (Suzhou) Co., Ltd. It is not the AGM materials or presentation itself (AGM-R), nor merely a voting results announcement (DVA), nor a standard corporate report (10-K, IR, ER, etc.), but rather a legal opinion accompanying the shareholder meeting. There is no specific category for legal opinion letters under the definitions provided. Therefore, this falls under the fallback category for miscellaneous regulatory submissions: Regulatory Filings (Code: RNS).
2026-05-18 Chinese
关于股东减持计划实施完毕暨减持股份结果公告
Major Shareholding Notification Classification · 96% confidence The document is a shareholder announcement (“股东减持股份计划实施完毕暨减持股份结果公告”) detailing the completion of a substantial shareholder’s reduction of holdings (from 5.92% down to 4.92%), including quantities, dates, methods and compliance statements.
