In recent years, China Bester has maintained rapid growth. While developing in an endogenous way, it also regards the growth of extended mergers and acquisitions as a powerful supplement for the company to become bigger and stronger. Especially after being listed on the main board of the Shanghai Stock Exchange in 2018, China Bester's capital status and financing capacity have taken a qualitative leap, further increasing the intensity of corporate mergers and acquisitions. China Bester adheres to the idea of M&A based on the main business and strengthening the core competitiveness, which is mainly reflected in improving the business layout, enhancing the service capacity, strengthening the weakness and extending the industrial chain.

In terms of improving its business layout, China Bester has carried out a series of M&A focusing on strengthening its professional and technical service capabilities and key service areas: in 2019, China Bester acquired Tianjin Posts and Telecommunications Design Institute in order to improve its survey and design service level and strengthen its technical talent strength. With the strong support of China Bester, the business of Tianjin Design Institute has expanded from the original China Unicom and China mobile to China Telecom, China Tower and ICT fields. In terms of management, the whole life cycle project management of China Bester company is grafted to improve its own project management ability.

In 2020, in order to expand the comprehensive maintenance service capacity, China Bester acquired Guangdong Minnov Technology Co., LTD step by step. After the acquisition, China Bester's comprehensive maintenance service area and service capacity have been improved. In order to cooperate with the company's international business development and improve its international layout, China Bester also acquired Ploywin, a local communication technology service provider in Hong Kong, to carry out broadband access projects in Hong Kong. Through the above acquisition, China Bester has the ability to provide integrated services covering design, construction and maintenance, which not only promotes business development, but also lays a good foundation for China Bester to carry out EPC business at home and abroad.

While actively exploring 5G new infrastructure business, China Bester has also laid out its business area around smart city and 5G industry applications. In May 2021, China Bester acquired Wuhan Tongsheng Transportation Facilities Co., LTD., which was competitive in industry qualification, market resources, project delivery and intelligent transportation system solutions, so as to enhance the company's comprehensive service capabilities in intelligent transportation, smart city and expand business volume. In addition, China Bester has made great efforts in the operation and technical services of shared e-bike platform, and has continuously tapped the growth point of intelligent transportation.

In order to complete the extension of upstream and downstream industry chain, the Group took a controlling stake in Wuhan Info-eternal Optoelectronics Co.,Ltd. in 2020 and Jingmen Rayzer Optoelectronics Technology CO., Ltd. in 2021. Rayzer's passive wave division products and Wuhan Info-eternal active optical modules are fully complementary, which can fully meet the needs of operators' communication network construction. In addition to the product quality and production capacity of the two companies have been fully recognized by customers, Rayzer has made progress in the field of laser radar for automatic driving, and will later cooperate with international well-known companies that produce vehicle laser radar to enter the field of automatic driving.

Through M&A, while giving full play to the original advantages, relevant enterprises can combine the brand, capital, resources and enterprise management advantages of China Bester to promote the development of various businesses, improve the comprehensive service capacity and core competitiveness of China Bester in relevant fields, and the overall profitability of the group.

In the future, focusing on smart city, 5G industry application and information and innovation industry, China Bester will increase its strength of equity participation, M&A and integration for enterprises and teams with technological advantages and characteristic products, so as to enhance the company's ICT technology research and development and overall solution capabilities according to its own strategic development plan and business development needs .
