Core ideas:
1. The company focuses on the field of aviation maintenance and microelectronics, and is a trinity high-tech enterprise with core equipment R & D and manufacturing, microelectronics, aviation engineering technology and services as its main business. The company's products are related to high-end equipment, commercial civil aviation and high-performance integrated circuit manufacturing, including aviation maintenance, aviation engineering technology and services, semiconductor manufacturing, 5G mobile communications, AI artificial intelligence, radar, automotive electronics, power electronics, optical fiber communications, 3D sensing, new energy, defense and other fields.
2. Aviation maintenance and maintenance business is still the main source of business income, and the proportion of microelectronics business income is increasing year by year. The company's current main business can be subdivided into five major businesses: aviation maintenance, core equipment R & D and manufacturing, aviation training, aviation leasing and microelectronics. In terms of operating income, aviation maintenance, maintenance, leasing and R & D manufacturing contributed mainly to revenue, but the proportion continued to decrease, and the microelectronics business began to accelerate the output value in the harvest period. In 2015-19, the contribution of the company's aviation maintenance, maintenance, leasing and R & D manufacturing business to revenue in the same period gradually decreased, from 76.69% in 2015 to 52.23% in 2019. The output value of the company's microelectronics business in the semiconductor field has gradually increased, and the proportion of revenue has increased from 4.74% in 2018 to 10.99% in 2019. The operating income of Haiwei Huaxin, a subsidiary engaged in this business, has increased rapidly from 4 million yuan in 2017 to 89 million yuan in 2019. In terms of profits, the company's overall gross profit margin has declined in recent years, but the decline has gradually slowed down. It is expected that with the increase in the proportion of revenue from the microelectronics business with high gross profit margin and expected fast growth, the overall gross profit margin is expected to stabilize and pick up. Affected by the intensification of competition in the original business market and changes in the business structure, the company's overall gross profit margin has dropped from 56.67% in 2015 to 41.85% in 2019, but the overall decline has slowed down, and the gross profit margin has remained around 41.84% in the past three years. Affected by the effect of scale, the release of production capacity and the improvement of demand, the gross profit margin of the company's microelectronics business has increased rapidly, from 34.90% in 2018 to 49.50% in 2019.

In terms of special equipment business, the company expanded more than 100 customers in 2019 and has more than 60 fixed customers, including core mainstream customers such as aerospace and communications. With the support of the equipment department, the company has obtained 18 targeted projects of science equipment products in 2019, ranking high. It is expected that the scientific research tasks will be completed and all of them will be converted into mass production within half a year to two years, becoming a stereotyped project in the equipment department. The company expects that the order of the department will reach more than 100 million in 2020, a substantial increase compared with 2019. In the field of civil products, the company focuses on 5G and other directions that have a high threshold and have a traction effect on the compound semiconductor industry. In 2019, the company has completed all the process research and development in the field of 5G base stations, and the RF GaN of 5G macro base stations has passed the reliability verification, which can provide a lower cost and more efficient chip manufacturing solution for 5G technology, and also marks that the company can provide manufacturing services for base station products.
The company said that in 2020, it will further increase the research and development of filters and SiC MOSFET products, and expand the production capacity of mass-produced products, achieve two-way expansion horizontally and vertically, and seize the construction opportunities of macro base stations and micro base stations.
(3) the third generation semiconductors represented by GaN mainly apply power electronics, microwave radio frequency and optoelectronics. GaN is one of the most potential semiconductor materials in the communication base station application field in the future. 5G communication popularity and domestic substitution acceleration in the core semiconductor field are expected to contribute to the momentum of business growth. According to the April 2019 journal "5G key Materials-A brief Analysis of the third Point Semiconductor material Market Development", GaN and SiC are also called the duo of the third generation semiconductors. Because of its large band gap, high breakdown electric field and stable chemical properties, GaN is one of the third generation semiconductor materials with the most potential for growth in the future in the field of communication base station applications. According to "focusing on the key technologies of the industry and seizing the development opportunity of the third generation semiconductors", the application of 5G communications will vigorously promote the industrialization of the third generation semiconductors. The transformation of the communications industry to the 5G era is expected to reshape the status quo of the radio frequency technology industry, or it will bring greater market opportunities for GaN radio frequency devices. According to the first document quoted in this paragraph, the global market for GaN radio frequency devices reached 3.1 billion yuan in 2018, of which the scale of base station-side GaN radio frequency devices is about 1.3 billion yuan. By 2023, the market size is expected to reach 9 billion yuan, with CAGR exceeding 23%. Among them, the market size of base station-side GaN radio frequency devices is expected to exceed 3.5 billion yuan.
