Investment Rating - The report maintains a "Buy" rating for the company, indicating an expected relative price increase of over 15% [4]. Core Insights - In 2024, the company achieved total revenue of 3.41 billion yuan, a year-on-year increase of 21.46%, and a total profit of 266 million yuan, up 37.7%. The net profit attributable to shareholders was 189 million yuan, reflecting a modest growth of 1.09%. The significant growth in revenue and total profit is primarily attributed to the consolidation of the gas operation business in Q2 2024, while traditional coal chemical equipment and engineering businesses performed steadily. The gross margin for core equipment is expected to remain stable [1][2]. - The company is strategically positioning itself in the green hydrogen and green alcohol industry chain, focusing on core equipment such as electrolyzers, gasifiers, and purification devices. This transition from coal chemical to green chemical is anticipated to create a second growth curve for the company's profits as the penetration rate of green hydrogen and hydrogen-based products increases [1][3][12]. Summary by Sections Coal Chemical Main Business - In 2024, revenue from coal efficient utilization reached 1.82 billion yuan with a gross margin of 24.7%. The expected revenue from EPC/design/consulting is estimated at 500-600 million yuan with a gross margin of 5-8%. Revenue from gasifiers is projected to be between 1.3 billion and 1.4 billion yuan, maintaining a gross margin of approximately 30% [3]. - High-end equipment manufacturing generated 300 million yuan in revenue with a gross margin of 28.7%, primarily from valve manufacturing, which was separately reported from equipment sales in 2023 [3]. Industrial Gas Operations - In April 2024, the company increased its stake in the previously affiliated company, Aerospace Hydrogen Energy, to 34.35%, becoming its controlling shareholder and consolidating it into the company's financial statements. This acquisition has made the industrial gas operation business a significant part of the company's operations, with ongoing projects such as the Cangzhou gas phase II project exceeding 80% completion and the successful commissioning of the Xinxiang gas project [3][11]. Hydrogen Energy Industry Chain Core Equipment - The company has made significant progress in the hydrogen energy industry chain, completing tests on a 2000-type alkaline water electrolyzer prototype, achieving leading domestic performance. Development of PEM electrolyzers in various capacities is ongoing, and the electrolyzer manufacturing process has been certified under three systems. The company has also received energy efficiency certification from the China Hydrogen Energy Alliance [12]. - The first hydrogen deep purification system and trace impurity removal system have completed trial operations, which can be used for purifying hydrogen from chemical by-products. The company possesses biomass gasification technology and equipment reserves, which are expected to contribute to profit growth as the industry transitions from coal chemical to green chemical [12][13]. Financial Projections - The company forecasts revenues of 5.42 billion yuan, 6.24 billion yuan, and 6.87 billion yuan for 2025, 2026, and 2027 respectively, with corresponding net profits of 236 million yuan, 310 million yuan, and 345 million yuan. The projected P/E ratios for these years are 38, 29, and 26 times [14][13].

1. Report Industry Investment Rating No relevant content provided. 2. Core Viewpoints of the Report - Rating downgrades in the convertible bond market from 2021 - 2024 showed high - frequency, seasonal, and industry - concentrated characteristics. Over 61% of downgrades were in June, with cyclical industries like industrial and materials dominating, and over 80% of downgraded entities being private enterprises in coastal developed areas. High - rating entities had lower downgrade risks [6]. - Rating adjustments drove market differentiation. High - growth sectors such as TMT, electronics, and non - ferrous metals had low downgrade risks, while industries like real estate, steel, and power equipment faced greater downgrade pressure. After a downgrade, convertible bond prices generally showed a "first decline then rise" pattern, and market sentiment was significantly affected by the rating window period [6]. - To deal with credit risks, a triple - strategy approach could be adopted: using equity - biased convertible bonds to hedge risks, seizing repair opportunities of undervalued low - price bonds, and using short - duration high - YTM bonds for defense [6]. 3. Summary According to Relevant Catalogs 3.1 Rating Adjustment Review 3.1.1 Historical Rating Adjustments and Market Performance - From 2021 - 2024, there were 193 downgrades in the convertible bond market, accounting for 4.51% of all rating adjustments. Over 61% of them were in June. Industries such as industrial and materials were dominant, private enterprises accounted for over 80%, mainly in coastal areas like Guangdong and Jiangsu. Downgraded entities were generally of weak quality, with issuance ratings concentrated at AA and AA - [6][8][10]. - The broader market index often weakened in May and June. The CSI Convertible Bond Index usually had a phased decline before the release of rating adjustment announcements due to risk pre - screening by institutions, leading to a chain reaction of "forward - priced risk → wider credit spread → market correction" [16]. - After a downgrade, convertible bond prices generally showed a "first decline then rise" pattern. For example, Zhongzhuang Zhuan 2 and Ying 19 Convertible Bond rebounded about 1 month after the downgrade [19]. 3.1.2 Identification of Downgraded Convertible Bonds - Factors leading to rating downgrades included performance losses, weakened solvency, low industry prosperity, equity issues, and liquidity risks. For example, Lingnan Convertible Bond was downgraded multiple times due to a plunge in EBITDA margin to - 119% and a high short - term debt ratio [6][23][24]. 3.1.3 Rating Adjustments Showed Structural Differentiation - High - growth sectors such as TMT, electronics, and non - ferrous metals had strong profitability and low downgrade risks. For example, the computer industry had a 471.86% year - on - year increase in net profit, the electronics industry had a ROE of 6.27% and a 37.24% net profit growth, and the non - ferrous metals industry had a ROE of 11.3% and a 53.23% net profit growth [26]. - Traditional industries such as real estate, steel, and power equipment faced greater downgrade risks. The real estate industry had a 274% drop in net profit, the steel industry had a negative ROE, and the power equipment industry had a low ROE of 3.6% [28]. 3.2 How to Select Bonds Around the Rating Adjustment Window Period 3.2.1 Equity - linked Convertible Bonds Could Hedge Credit Risks - In the face of credit risk shocks, equity - biased convertible bonds showed stronger price resilience. For example, during the "20 Hongda Xingye SCP001" default in 2020, equity - biased convertible bonds rose while others declined [32]. 3.2.2 Low - price Convertible Bonds Presented a Layout Window - During the credit adjustment window period, the low - price index usually showed a "first decline then rise" return characteristic. In 2024, low - price convertible bonds initially underperformed but later achieved the highest cumulative return for the year. Currently, attention could be paid to undervalued but cash - flow - stable bonds [33]. 3.2.3 Layout of Short - duration High - YTM Convertible Bonds - Short - duration high - YTM convertible bonds with a remaining term of less than 2 years and positive YTM could be selected. For example, Wanshun Zhuan 2 in 2024 outperformed the market under the protection of the put - back clause [36]. 3.3 Post - market Allocation Suggestions - Focus on three types of opportunities: high - growth equity - biased convertible bonds such as Hao 24 Convertible Bond; low - price bonds with credit mispricing like Jingneng Convertible Bond; and short - duration high - YTM defensive bonds such as Lvyin Convertible Bond [40].
