中微公司董事长尹志尧减持股份，股价短期承压但基本面支撑仍存

Core Viewpoint - The recent share reduction by the chairman of the company due to personal tax arrangements may exert short-term pressure on market sentiment and stock prices, but the company's strong business growth and industry-leading position provide long-term value support [1]. Executive Changes - Since February 2026, the chairman and general manager has repeatedly reduced his shareholding through centralized bidding, including reductions of 30,000 shares at an average price of 350.88 CNY/share on February 9, 2026, 14,000 shares at 354.46 CNY/share on February 6, 2026, 22,000 shares at 350.86 CNY/share on February 4, 2026, and 32,000 shares at 345.11 CNY/share on February 3, 2026. These reductions are due to personal tax arrangements and do not exceed 0.046% of the total share capital, in line with prior disclosure plans [2]. Stock Price and Fund Performance - Following the reduction announcement, the company's stock price fell to 346.86 CNY on February 11, 2026, a decrease of 1.04% from the previous day, with a net outflow of 55.32 million CNY in main capital, indicating that the reduction event may exacerbate short-term selling pressure. The current price-to-earnings ratio stands at 113.48, significantly higher than the industry average, suggesting that executive reductions may amplify valuation correction risks [3]. Performance and Operating Conditions - The company's fundamentals show resilience, with revenue of 8.063 billion CNY in the first three quarters of 2025, representing a year-on-year growth of 46.40%. Revenue from thin-film deposition equipment reached 403 million CNY, a staggering increase of 1332.69%, and the acquisition of a CMP equipment manufacturer is expected to enhance the upstream process layout. Strong performance growth may partially offset the negative impact of the share reductions [4]. Institutional Perspectives - Despite recent reductions by some index funds, institutional ratings remain predominantly "buy" or "add," indicating that long-term confidence has not fundamentally wavered [5]. Industry Policy and Environment - The trend towards domestic production of semiconductor equipment is clear, and the company's technological leadership supports long-term value. However, attention should be paid to the potential diversion of investment focus due to the self-research wave in AI chips [6]. Future Development - Potential risks include further share reductions by major shareholders, which may suppress stock prices; concentrated executive reductions could trigger retail investor sell-offs, raising liquidity risks; and a slowdown in global semiconductor equipment capital expenditure growth may impact the company's order growth momentum. Overall, while the executive reductions may increase stock price volatility and capital outflow pressure in the short term, the company's fundamentals and industry prosperity still provide support [7].
