Filing Released Lang Actions
国浩律师（杭州）事务所关于实朴检测技术（上海）股份有限公司2023年限制性股票激励计划部分已授予尚未归属限制性股票作废事项之法律意见书
Regulatory Filings Classification · 85% confidence The document is a standalone legal opinion letter (“法律意见书”) prepared by Grandall Law Firm for the company’s 2023 restricted stock incentive plan, specifically concerning the cancellation of certain unvested shares. It contains no financial statements or voting results, nor is it an earnings release, regulatory notice of interest rate, or M&A document. It is part of the compliance/submission materials for a share incentive scheme and does not fit any specialized category, so under the fallback it should be classified as a general regulatory filing (RNS).

国浩律师（杭州）事务所关于实朴检测技术（上海）股份有限公司2025年年度股东会之法律意见书
Regulatory Filings Classification · 91% confidence The document is a legal opinion letter issued by Grandall Law Firm regarding the convening, procedures, attendees, agenda, voting process, and voting results of the company’s 2025 Annual General Meeting (AGM). It is an attestation of the meeting’s legality and procedure rather than the AGM materials themselves or a standalone vote-results announcement. Under the “Certification Rule,” such legal opinions or attestation letters should be classified as Regulatory Filings (RNS) rather than as AGM presentations (AGM-R), vote-result declarations (DVA), or other specific report types.

关于召开2026年第一次临时股东会的通知
Proxy Solicitation & Information Statement Classification · 85% confidence The document is a formal notice convening the company’s first 2026 interim shareholders’ meeting (临时股东会), including meeting logistics, agenda, proxy authorization form, and voting instructions. It is sent to shareholders to provide information and solicit votes for the meeting, which matches the definition of a Proxy Solicitation & Information Statement.

关于作废部分已授予尚未归属的限制性股票的公告
Share Issue/Capital Change Classification · 85% confidence The document is a corporate announcement detailing the cancellation (“作废”) of portions of granted but unvested restricted shares under the company’s 2023 restricted stock incentive plan, including board and shareholder meeting approvals and share quantities. This is not a financial report, earnings release, or management discussion, nor is it an actual repurchase of shares on the market. Rather, it constitutes an internal capital structure change concerning the company’s share capital (cancellation of reserved equity). Under the filing definitions, this falls under “Share Issue/Capital Change” (Code: SHA).

国泰海通证券股份有限公司关于实朴检测技术（上海）股份有限公司2025年度持续督导跟踪报告
Regulatory Filings Classification · 82% confidence The document is a continuous supervision (ongoing sponsor tracking) report prepared by the sponsor (Cathay Haitong Securities) for a listing company, detailing review and compliance work, supervisory findings, and follow-up measures. It is not a company’s annual or interim financial report, nor an earnings release, proxy statement, or management presentation. It is effectively a regulatory compliance filing submitted to the exchange and does not match any specific category (10-K, IR, AR, etc.). It therefore falls under the fallback “Regulatory Filings (RNS)” category.
2026-05-11 Chinese
国泰海通证券股份有限公司关于实朴检测技术（上海）股份有限公司2025年度持续督导工作现场检查报告
Regulatory Filings Classification · 82% confidence The document is not a standard financial report (10-K, IR, ER) or management presentation; it is a sponsor’s on-site inspection report relating to continuous regulatory supervision work. It contains detailed compliance checklists and findings rather than financial statements or announcements of dividends, board changes or financing. It does not fit any specific category like Interim Report (IR) or Audit Report (AR) which applies to accounting audits. Therefore, it falls under the fallback category of general regulatory filings (RNS).
