5. Expected operating performance in 2021 and sustainability of performance growth

(1) Expected operating performance in 2021

Benefiting from the strong downstream demand and the growing number of orders, the issuer expects the operating performance in 2021 as follows:

Unit: 10000 yuan

Year on year change rate of the project from 2021 to 2020

Year on year change rate of the project from 2021 to 2020

Operating income 127104998384734 51.59%

Net profit attributable to owners of parent company 1628416576395 182.52%

Net profit attributable to 1537731, 557239 and 175.96% of the owners of the parent company after deducting non recurring profits and losses

(2) Sustainability of performance growth

The downstream PCB industry has large space and rapid demand growth, which promotes the growth of China's electronic circuit copper foil market demand, and the localization proportion of high-performance copper foil products has increased, so the market prospect of China's electronic circuit copper foil industry is good; Through continuous research and development, the issuer continuously optimizes the product structure, and the proportion of high-end copper foil products is expected to continue to increase. On the premise of no significant adverse changes in the upstream and downstream of the industry and market supply and demand, the issuer's electronic circuit copper foil processing fee and sales revenue are sustainable to a certain extent; The issuer's implementation of vertical integrated development of PCB industrial chain can avoid the cyclical risk of a single product and improve the stability of the issuer's profitability. The specific analysis is as follows:

① The prospect of supply and demand structure of copper foil for electronic circuit is good 1

The downstream industry of electronic circuit copper foil has wide application fields, large market space and continuous growth of downstream demand. According to the prediction of HSBC Qianhai securities, the average annual compound growth rate of China's PCB output value from 2020 to 2025 is about 8%; It is estimated that the annual incremental demand of China's electronic circuit copper foil industry from 2020 to 2025 will be about 39000 tons, and the total demand is expected to be 448400 tons, 484300 tons, 523000 tons and 564900 tons;

In recent years, the expansion projects of copper foil enterprises are more concentrated in the field of lithium battery copper foil, and they are more cautious about the expansion of electronic circuit copper foil. Affected by the expansion cycle of about 24 months, according to the expansion plan of copper foil industry companies, from 2021 to 2024, China's annual new production capacity is expected to be 14400 tons, 21900 tons, 30000 tons and 22500 tons respectively, and the total production capacity is expected to reach 349800 tons, 371700 tons 401700 tons and 424200 tons.

Therefore, the supply and demand structure of copper foil for electronic circuits has a good prospect.

② Optimize the product structure and increase the proportion of high-end products

At present, the issuer has achieved 12 μ M ultra thin copper foil and 105 for HDI board μ The mass production and sales of m-thick copper foil has the ability of localization substitution in the field of ultra-thin copper foil and thick copper foil, and its processing cost is high. With the expansion of market demand, the increase of localization proportion and the upgrading of issuer's process technology and product structure in the future, the proportion of high-end and high-performance products such as ultra-thin copper foil and thick copper foil is expected to continue to increase, driving up the overall processing fee. 1. The following prediction of the future market demand and supply of electronic circuit copper foil is calculated according to the growth of PCB industry and the expansion of industry production. If there are great changes in the downstream and the same industry in the future, the market demand and supply may be adjusted.

In addition, from 2019 to the first half of 2020, due to trade friction, covid-19 epidemic and other factors, the prosperity of electronic circuit copper foil industry is low. Under this background, the issuer's capacity utilization rate and production and marketing rate from 2018 to 2020
