His resignation from the positions of director, chairman, and chairman of the board's strategy committee took effect on June 5, 2026, upon delivery to the board.

The company will promptly proceed with the process of electing a new director and chairman.
Yingxin Development Co., Ltd. has announced that its enterprise-grade DRAM storage products, primarily used in servers and data centers, have achieved mass production and are being delivered in batches. The company's enterprise business is in a phase of accelerated expansion. It is noted that cloud service providers have extremely high requirements for suppliers' technical capabilities, product reliability, delivery capacity, and service quality, and the testing and certification cycles are lengthy. Specific details should be referred to the company's official disclosures. Changxing Semiconductor focuses on building full-chain capabilities for semiconductor storage application products, possessing comprehensive capabilities in chip design (USB flash drives), firmware algorithm development, packaging and testing, and module manufacturing, providing consumer-grade, industrial-grade storage chips, and industry-specific storage hardware and software application solutions to the market.

Upon resumption of trading, the stock's abbreviated name will change to "Fanli Technology," and the daily price fluctuation limit will be adjusted from 5% to 10%. The delisting risk warning was initially applied on April 28, 2025, because the company's audited net profit for 2024 was negative, and its operating revenue after deducting income from businesses unrelated to its main operations and income without commercial substance was below 300 million yuan. For the 2025 fiscal year, the company's audited figures are as follows: total profit: -67.2041 million yuan; net profit attributable to shareholders: -63.3278 million yuan; net profit attributable to shareholders after deducting non-recurring gains and losses: -49.7614 million yuan; operating revenue after deducting income from businesses unrelated to its main operations and income without commercial substance: 486 million yuan; and audited net assets attributable to shareholders at the end of the reporting period: 396 million yuan.

The company's main business involves borosilicate pharmaceutical packaging glass products and high borosilicate heat-resistant glass products. In response to recent high market attention regarding the application of glass substrates in the semiconductor field, the company clarifies that it is exploring new application areas such as glass substrates and glass-ceramics. Related products are still in the R&D, testing, or sample submission stage and have not yet generated any related revenue. The company's main business remains unchanged. This R&D endeavor carries the risk of failure and potential operational losses. There is significant uncertainty regarding whether these products can be successfully industrialized for mass production, secure orders, and generate operating income in the future.
Xinke Materials Co., Ltd. has announced that on June 5, 2026, it held its tenth board of directors' seventh meeting and reviewed and passed a proposal to terminate its 2026 plan for a private placement of A-shares to specific investors and to withdraw the application documents.

The net proceeds were intended to repay bank loans and supplement working capital.
Sanfu Co., Ltd. has announced a shareholding reduction. On February 7, 2026, the company disclosed a shareholder reduction plan, where Tangshan Yuanheng Technology Co., Ltd. planned to reduce its holdings between March 9, 2026, and June 8, 2026. The plan included reducing no more than 1% of the total shares via centralized bidding and no more than 2% via block trading. The company has verified that during the recent period of abnormal stock price volatility, Yuanheng Technology did reduce its holdings, consistent with the previously disclosed plan. The reduction plan has now been completed. In a separate announcement on the same day detailing the reduction results, the company stated that on June 5, 2026, Yuanheng Technology sold 3.82 million shares (1% of total shares) via centralized bidding, with a total value of approximately 200 million yuan and a price range of 50.55 to 52.82 yuan per share. Following this transaction, Yuanheng Technology's shareholding decreased to 97.1443 million shares, representing a 25.3889% stake. This reduction plan was completed ahead of schedule.
Zhongzhong Technology Co., Ltd. has announced that its main business involves the R&D, process design, production, technical services, and sales of intelligent rolling equipment and complete production lines for the metallurgical sector. Its core products include fully automated rolling production lines and related spare parts for hot-rolled sections, strip steel, bar and wire rod, and medium and heavy plates. The company is classified under the special equipment manufacturing industry. All of its operating revenue during the reporting period was derived from this main business of metallurgical intelligent equipment. The company's main business remains unchanged, and it is not involved in the production or manufacturing of robots or their components.
Microgate Technology Co., Ltd. has provided clarification in response to market attention on certain products and clients within its electronic components business. The Bias-Tee (biaser) module is a passive device the company has been supplying to optical module manufacturers since 2023, suitable for internal laser driver and signal transmission applications. The company's magnetic beads are also applicable in optical module scenarios. Currently, revenue from this product constitutes a small proportion of the company's total operating revenue and has a limited impact on its performance. However, this product is an essential component for optical modules and remains one of the company's key products for promotion in the optical module market. The high-frequency, high-power, high-voltage customized isolation transformer project for SST (Solid State Transformer) is a key technology roadmap product that the company's controlling subsidiary, Chengdu Jinzhichuan Electronics Co., Ltd., has been co-developing with a client since 2023. Jinzhichuan has completed initial samples with the client and is currently conducting testing and verification. This product has the potential to become a mainstream solution for high-power data center power supply in the future, but industrialization still requires long-term validation from downstream clients. Regarding clients, the company has obtained open platform R&D project permissions from Nvidia. Currently, some integrated molding and high-computing-power copper-iron co-fired inductor part numbers have achieved small-batch trial production, but uncertainties in the international trade environment and other external factors may impact subsequent product promotion and volume growth.
LabTech Instruments Co., Ltd. has issued a clarification regarding recent market discussions about its Inductively Coupled Plasma Mass Spectrometer (ICP-MS) series products, including the LabMS3000 ICP-MS and LabMS5000 ICP-MS/MS. The company stated that the discussed content was not officially released by the company and constitutes speculative market rumors. In 2025, the total sales revenue from these products was 32.203 million yuan, accounting for 8.03% of the company's total operating revenue of 401.08 million yuan. Furthermore, the industries served by these products primarily include environmental protection, disease control, customs inspection, semiconductors, healthcare, and universities. Revenue from the semiconductor sector remains very limited within this product category. The company solemnly reminds investors that the progress of related business expansion, the scale of subsequent orders, and profit contributions are all subject to high uncertainty. Investors should not equate market rumors with the company's performance commitments.
Shengyang Technology Co., Ltd. has announced a plan for a private placement of A-shares to specific investors to raise no more than 1.076 billion yuan.

Fuchuang Precision Co., Ltd. has announced that the time window for a previously disclosed shareholding reduction plan by a shareholder and certain directors and senior executives expired on June 5, 2026.

The original plan was to reduce up to 3.00%, which was not fully executed. Director and Deputy General Manager Ni Shiwen reduced 6,633 shares (0.0022%), completing his plan. Director and Deputy General Manager Song Yang reduced 2,948 shares (0.0010%), completing his plan. Deputy General Manager Song Yansong reduced 3,445 shares (0.0011%), completing his plan.

Concurrently, the company plans to raise supporting funds of no more than 175 million yuan from no more than 35 specific investors to pay the cash portion of the transaction consideration, intermediary fees, and related taxes. This transaction constitutes a connected transaction but does not constitute a backdoor listing. The assessed value of the target assets using the income approach is 1.07 billion yuan, representing a premium of 128.38%.
