Major Shareholding Notification Classification · 100% confidence The document is titled "详式权益变动报告书" which translates to "Detailed Equity Change Report." It is issued by Shanghai Tieda Telecom Technology Co., Ltd. and details a significant change in shareholding involving the transfer of a 99% partnership interest in a fund that holds shares in the listed company.

This matches the definition of a Major Shareholding Notification (Code: MRQ), which covers notifications of changes in significant share ownership levels crossing thresholds. It is not an announcement of a report publication, nor a general regulatory filing, nor a proxy or voting result document. Therefore, the correct classification is MRQ with high confidence.
