Core Viewpoint - Hangzhou Steam Turbine Power Group Co., Ltd. and Hangzhou Hailianxun Technology Co., Ltd. are set to undergo a share swap merger, marking the first successful "B to A" conversion in the B-share market in three years, reflecting the deepening reform of state-owned enterprises in Hangzhou and the acceleration of high-quality development in advanced manufacturing [3][4][5]. Group 1: B to A Conversion - The "B to A" conversion allows the company to transition from B-shares, aimed at foreign investors, to A-shares, which target a broader investor base [4]. - Hangzhou Steam Turbine has faced limitations in capital market financing due to the constraints of the B-share market, having raised only 1.71 billion HKD since its establishment [4][5]. - The conversion is expected to enhance the company's value and liquidity, attracting more institutional and individual investors, and improving the overall shareholder structure [5]. Group 2: Strategic Importance - The merger is a response to policy guidance and market opportunities, aimed at strengthening the state-owned enterprises and enhancing resource integration [7]. - The integration is anticipated to create a win-win situation, with Hangzhou Steam Turbine leveraging Hailianxun's A-share platform to inject new growth into its high-end equipment manufacturing business [7]. - The combined market capitalization of both companies has exceeded 20 billion RMB, reflecting positive market expectations regarding the merger [7]. Group 3: Future Development - Hangzhou Steam Turbine aims to become a world-class smart energy service provider, transitioning from a manufacturing-focused model to a technology and service-oriented approach [9]. - The company has invested approximately 1 billion RMB in the development of its self-developed gas turbine over 11 years, with plans for further advancements in this area [8][9]. - The successful "B to A" conversion and the ignition of the self-developed gas turbine mark a new starting point for the company's growth trajectory [9].

Core Viewpoint - Hangzhou Steam Turbine Power Group Co., Ltd. (referred to as "the Company" or "Hangzhou Steam Turbine") will undergo a stock suspension and a share exchange merger with Hangzhou Hailian Technology Co., Ltd. (referred to as "Hailian Technology") starting from November 5, 2025, with the last trading day being November 4, 2025 [1][6][16]. Summary by Sections Cash Option Distribution and Implementation - The cash option record date is set for November 4, 2025, after which the distribution will proceed, allowing shareholders to exercise their rights at a price of 7.54 HKD per share, equivalent to 6.90 CNY per share [2][10][25]. - Shareholders can exercise their cash options during specified hours on the declaration day, and the company warns that exercising these options may lead to losses due to the current trading price being higher than the exercise price [2][10][19]. Share Exchange Merger - Following the completion of the cash option exercise and settlement, the Company will announce the share exchange record date, allowing shareholders to convert their shares into Hailian Technology shares at a 1:1 ratio [3][11][12]. - Hailian Technology will inherit all assets, liabilities, and rights of Hangzhou Steam Turbine upon completion of the merger, which will result in the termination of Hangzhou Steam Turbine's listing and legal status [9][11][16]. Important Dates and Procedures - The last trading day for Hangzhou Steam Turbine shares is November 4, 2025, with a continuous suspension starting November 5, 2025 [1][6][16]. - Shareholders must ensure their shares are not pledged or frozen to exercise their cash options, and any unexercised options will be canceled after the declaration period [24][34]. Contact Information - For inquiries, shareholders can contact the designated representatives at Hangzhou Steam Turbine, with provided contact details for further assistance [13][14][37].

Core Viewpoint - The absorption merger of Hangzhou Turbine (杭汽轮) by Hailianxun is expected to establish a new corporate governance structure, optimize management, and enhance the company's development quality without affecting its current operations [1][3]. Group 1: Company Operations - Hangzhou Turbine's daily operations have not experienced any adjustments or fluctuations during the merger process [3]. - The company has successfully completed critical testing phases for its gas turbines, including compressor, turbine, and combustion chamber experiments, achieving successful ignition in May and completing full-speed and full-load tests [5]. Group 2: Financial Performance - For the first three quarters of 2023, Hangzhou Turbine reported revenues of 3.825 billion yuan, a year-on-year decline of 10.27%, and a net profit attributable to shareholders of 123 million yuan, down 35.14% year-on-year [5]. Group 3: Strategic Development - The merger is a significant step for Hangzhou Turbine B to transition from B-shares to A-shares, aiming to create a synergistic development model of "high-end equipment manufacturing + power information" and move towards the goal of becoming a "world-class industrial driving service provider" [5].
