Filing Released Lang Actions
北京市中伦（深圳）律师事务所关于兆易创新2021年、2023年、2024年股权激励计划调整相关事项的法律意见书
Regulatory Filings Classification · 85% confidence The document is a standalone legal opinion (法律意见书) prepared by Zhong Lun law firm concerning adjustments to the company’s stock option and restricted share incentive plans. It does not itself contain financial statements, market data, or investor presentation material, nor is it announcing a dividend, share issuance, or M&A transaction. It is essentially a certification/attestation letter that accompanies a corporate action filing. Such legal opinion letters fall under the ‘Regulatory Filings’ (RNS) category as per the certification rule.

兆易创新关于调整2023年股票期权激励计划相关事项的公告
Regulatory Filings Classification · 81% confidence The document is a Chinese regulatory announcement (“公告”) detailing adjustments to the company’s 2023 stock option incentive plan, including board approvals, exercise price changes due to dividend distribution, cancellation of options, and repurchase of restricted shares. - It is not an Annual Report, Audit Report, Earnings Release, or similar financial report. - It is not a simple publication notice (RPA) or officer certification (RNS certification rule doesn’t apply here as there is substantive corporate action detail). - It is not a change in senior management (MANG), nor a voting result (DVA), nor a dividend notice (DIV) as the primary purpose. - It includes repurchase of restricted shares and cancellation of options, but the core is plan adjustment rather than a straightforward buyback (POS) or share issue/capital change (SHA). - It is best classified under generic Regulatory Filings (RNS), as it is a compliance announcement with no dedicated slot in our taxonomy.

兆易创新关于持股5%以上股东权益变动触及1%刻度的提示性公告
Major Shareholding Notification Classification · 92% confidence The document is a Chinese securities disclosure entitled “关于持股5%以上股东权益变动触及1%刻度的提示性公告,” detailing how a 5%+ shareholder’s stake has changed (from 7.90% down to 7.00%), triggering a 1% threshold tick. This perfectly matches the definition of a Major Shareholding Notification (Code: MRQ). It is not an earnings release, proxy statement, or other report, but a threshold-based shareholding change announcement.

兆易创新关于调整2021年股票期权与限制性股票激励计划相关事项的公告
Transaction in Own Shares Classification · 85% confidence The document is an official announcement detailing board and committee approvals concerning adjustments to the company’s 2021 stock option and restricted stock incentive plan, including the repurchase and cancellation of restricted shares and the adjustment of repurchase prices. As it describes the company’s own share repurchase actions rather than issuing new shares or providing financial results, it aligns with Transaction in Own Shares (POS).
2026-05-26 Chinese
兆易创新关于调整2024年股票期权激励计划相关事项的公告
Regulatory Filings Classification · 52% confidence The document is a corporate “公告” (public announcement) by a Chinese listed company detailing board and committee approvals and the adjustment of the exercise price under its 2024 stock option incentive plan due to a dividend distribution. It does not present actual financial statements (IR/10-K), nor is it an earnings release, proxy solicitation, merger filing, executive compensation proxy (DEF 14A), or investor presentation. It’s not about issuing new shares imminently or share repurchases but a regulatory announcement of an equity incentive plan adjustment. There is no specialized category for equity incentive plan adjustments, so this falls into the general regulatory announcement/fallback category (RNS).
2026-05-26 Chinese
兆易创新2025年年度权益分派实施公告
Notice of Dividend Amount Classification · 92% confidence The document is a formal corporate announcement by the board of MegaChip Innovation (stock code 603986) detailing the cash dividend per share for the 2025 fiscal year, record date, ex-dividend date, dividend payment date, total dividend amount, tax treatment for different shareholder categories, and implementation procedures. This matches the definition of a Notice of Dividend Amount (DIV), which covers announcements of dividend amounts, payment dates, and related details. It is not a report publication announcement, financial report, or regulatory filing fallback.
