Brilliant Technology: Located at the forefront of the rail transit market, it lays out traffic WiFi strategies. As a joint-stock high-tech enterprise focusing on traffic and traffic command automation, integrating scientific research, production and operation, Huihuang Technology has an advantageous position in the railway transportation and urban rail transit industry. The company focuses on product research and development, and relies on rail transit to carry out the strategic layout of traffic WiFi. We believe that Huihuang Technology has broad prospects for development and that the company has good growth potential. Demand for traffic WiFi is expanding, and the 100 billion market is waiting to be discovered. Huge traffic flows have spawned huge demand for traffic WiFi. As far as the whole country is concerned, there are very few WiFi supporting facilities in traffic scenarios, and they are still empty. Once they have sufficient capital and matching technology, they can occupy the 100 billion market. The full deployment of traffic WiFi is the general trend. Accelerate the strategic layout and enter the WiFi field. The company continues to increase investment in R&D to enhance the core competitiveness of product technology. The company relies on rail transit to enhance endogenous expansion capabilities, consolidate its market position, and promote the growth of various businesses. The company is also committed to expanding epitaxial business growth. It has successively invested in companies such as Flying Alliance, Safer Technology, and Colorful Access to actively develop Wi-Fi for mass transportation and build an integrated platform. Profit forecasting and investment ratings. We expect the company's revenue in 2016-2018 to be 699 million yuan, 888 million yuan and 1,131 million yuan respectively, and net profit attributable to shareholders of the parent company will be 100 million yuan, 138 million yuan and 169 million yuan respectively. Based on current share capital (no additional issuance has yet been considered), the corresponding EPS is 0.27 yuan, 0.37 yuan, and 0.45 yuan, respectively. Due to the steady development of Huihuang Technology's traditional main business, the “Big Transportation WiFi” strategy is progressing steadily, and it continues to maintain the “increase” rating. Stock price catalyst: The company received large orders; the transportation WiFi strategy implementation process exceeded expectations; the majority shareholders' fixed increase plan was successfully implemented. Risk factors: 1. Risk of declining national railway investment; 2. Risk of product technology innovation; 3. Risk of increased accounts receivable; 4. Management risk due to epitaxial expansion.
