Filing Released Lang Actions
第五届董事会第十二次会议决议公告
Regulatory Filings Classification · 0% confidence The document is a public announcement of the resolutions passed at the 12th meeting of the 5th Board of Directors of a listed company. It lists board approvals of the 2025 annual report, various work reports, financial statements, remuneration schemes, financing plans, internal control evaluations, governance rules, and other proposals, referencing that the detailed reports are published on the designated regulatory website. It is not the report itself (those are on the website), nor a shareholder voting result, nor a change in board composition, nor a financing notice, etc. It is a regulatory announcement of board meeting resolutions that does not fit any highly specific category, so it falls into the fallback “Regulatory Filings” category.

营业收入扣除情况的专项核查意见
Audit Report / Information Classification · 1% confidence The document is a standalone audit opinion (“专项核查意见”) issued by an accounting firm regarding the deduction of operating revenue for the 2025 fiscal year. It includes auditor responsibilities, scope, and an audit opinion, and is to be filed with the annual report. It is not the annual report itself, nor an earnings release or a short announcement, but a specific audit report. This matches the Audit Report / Information category (AR).

国泰海通证券股份有限公司关于长沙景嘉微电子股份有限公司2026年度日常关联交易预计的核查意见
Regulatory Filings Classification · 1% confidence The document is a formal disclosure by the sponsor (Guotai Huitong Securities) reviewing and providing opinions on the company’s expected daily related-party transactions for 2026. It is not a full annual or quarterly report, nor an earnings release, call transcript, management change, dividend notice, or other specific transaction notice. This type of corporate announcement of related-party transaction forecasts and sponsor opinions falls under the general regulatory disclosure category. Therefore, the appropriate classification is the fallback Regulatory Filings (RNS).

2025年度可持续发展报告
Environmental & Social Information Classification · 1% confidence The document is the company’s full 2025 Sustainable Development (ESG) Report, covering governance, environmental, social performance, stakeholder engagement, and sustainability practices. It follows GRI, SASB, and Shenzhen Stock Exchange guidelines for a sustainability report. This aligns exactly with the Environmental & Social Information category.

关于“质量回报双提升”行动方案的进展公告
Regulatory Filings Classification · 1% confidence The document is an announcement by Changsha Jingjia Microelectronics Co., Ltd. detailing the progress of its previously disclosed “Quality Return Double Enhancement” action plan, including R&D, governance improvements, investor communications, and shareholder return mechanisms. It is not an earnings release (no quarterly financial highlights), not an interim or annual report, not a call transcript, not a board or management change, and not a dividend notice. It does not simply announce the publication of another report but provides substantive progress details. As it doesn’t neatly fit any other specific category, it falls under the general “Regulatory Filings” fallback.

It is not an AGM presentation, annual or interim report, earnings release, board change notice, dividend notice, or any of the standard financial or governance filings. It is not a transcript, not a proxy solicitation, not a capital raising or M&A announcement, and not a share buyback or issuance notice. It represents a bespoke legal opinion on the company’s incentive plan, which does not match any specific category except the general “Regulatory Filings” fallback. Therefore, it should be classified under RNS.
