The banking business continues to advance rapidly. Other industries have blossomed a lot. In 2016, the company maintained a strong growth rate in the bank IT operation and maintenance market in traditional strong fields, with revenue of 605 million yuan, an increase of 64% over the previous year, adding 60 new bank customers; other business areas, such as telecommunications and commerce, all maintained high growth, with 16 new commercial customers and 15 new government customers. The company is gradually implementing the strategic plan of “IT operation and maintenance coverage in all fields” to seize the market space for IT operation and maintenance services. Equity incentives have shown results. Endogenous growth can be expected in 2017. The company implemented its first equity incentive in 2014. By the end of 2016, the first share incentive grant portion had all completed the performance assessment goals, and completed the stock unlock process. The first equity incentive effect was remarkable. The growth in 2015 and 2016 continued to exceed the average growth rate of the industry and exceeded market expectations. In 2016, the company launched the second phase of the equity incentive plan, which encouraged a total of 159 core employees, and the number covered doubled compared to the first phase of equity incentives. With 2017 and 2018 as assessment periods, the company's internal momentum is strong, and endogenous growth can be expected. Expectations for epitaxial mergers and acquisitions have increased, and it is expected that the company's expansion into fields other than banking and telecommunications will be the main driving factor for the company's future performance growth. In a situation where operation and maintenance automation technology, especially the cloud operation and maintenance market, have not yet formed a uniform standard and market pattern, it will be a wise choice for the company to start horizontal epitaxial mergers and acquisitions. Coverage for the first time, giving it a “buy” rating. With its strong service capabilities and channel network, Yinxin Technology has occupied a leading position in the domestic IT operation and maintenance market. Relying on traditional fields of advantage such as banking and telecommunications, the company is actively expanding into various other industries in a planned and rhythmic manner. Based on the industry market environment and the company's future development strategy, the company's revenue for 2017 and 2018 is estimated to be 1.52 billion yuan and 2.13 billion yuan, and net profit of 182 million yuan and 257 million yuan. Combining the company's position in the industry and channel advantages, it was covered for the first time and given a “buy” rating. Risk warning: 1. Domestic IT spending has declined rapidly, and the IT operation and maintenance market industry is declining; 2. New technology is progressing rapidly, changing the business model of the industry.
