Trends of companies listed on the main board
1. Gaomeng New Materials: 2023 annual performance forecast
Forecast period: January 1, 2023 - December 31, 2023.
Projected results: loss.
Explanation of the reasons for the change in performance:
1) In 2023, the company will further clarify and consolidate the "2+3" product strategy, actively explore the market, and achieve a slight increase in sales revenue, but due to increased R&D investment and strategic talent reserves, the company's operating profit will decline slightly;
2) Wuhan Huasen Plastics, a wholly-owned subsidiary of the company, was affected by the sharp decline in domestic production and sales of Japanese automobiles, and its operating performance declined sharplyabout 300 million yuan;
3) Jiangsu Ruipu Resin Technology, a holding subsidiary of 51% of the company's shares, has continued to lose money in the past 2 years, and has not reached the performance commitment, and it is expected that there will be greater pressure to turn around losses in 2024, and it will not be able to complete the 3-year performance commitment, and the company intends to provide for goodwill impairment of about 32 million yuan.
2. Strong new materials: 2023 annual performance forecast
Forecast period: January 1, 2023 - December 31, 2023.
The company's losses in the reporting period are mainly due to the following reasons: (1) During the reporting period, the demand of downstream customers decreased, and the company's main business income declined. During the reporting period, some projects under construction were transferred to fixed assets, and the interest was no longer capitalized, and the financial expenses increased. (2) The company has carried out impairment tests on various assets, and intends to accrue a loss of 8 million yuan for inventory decline. (3) During the reporting period, it is estimated that the impact of non-recurring gains and losses on net profit will be 20 million 28 million yuan, mainly for subsidies.
3. SkyOcean New Materials: 2023 annual results pre-loss announcement
SkyOcean New Material's net profit attributable to shareholders of listed companies in 2023 is expected to be -87 million yuan to -99 million yuan, a decrease of 30.41 million yuan to 42.41 million yuan compared with the same period last year, a year-on-year decrease of about 54% 75%. After deducting non-recurring gains and losses, the company's net profit attributable to shareholders of listed companies in 2023 is expected to be -98 million yuan to -110 million yuan, a decrease of 30.71 million yuan to 42.71 million yuan compared with the same period last year, a year-on-year decrease of about 46% 63%.
The main reasons for the pre-loss of this period are: (1) During the reporting period, the competition in the photovoltaic film market intensified, and the main raw material EVA particles continued to decline, resulting in a simultaneous decline in the price of photovoltaic film products; Due to the existence of the procurement cycle of EVA particles, the profit of the product was further compressed during the decline of raw materials, which lowered the company's overall gross profit margin and led to a decrease in net profit; (2) At the end of the reporting period, the raw materials of photovoltaic encapsulation film** declined, and according to the requirements of the relevant accounting standards for enterprises, the price decline of this part of the inventory was charged, resulting in a decrease in net profit during the reporting period; (3) During the reporting period, the company's photovoltaic film business developed rapidly, sales continued to increase rapidly, the company built new plants, added new production lines, and expanded the production and operation team according to the established plan.
4. Dongfang Materials: Announcement of the expected increase in annual results in 2023
According to the preliminary calculation of the financial department, Dongfang Materials expects to achieve a net profit attributable to shareholders of listed companies of 49.8 million yuan to 59.8 million yuan in 2023, an increase of 30.08 million yuan to 40.08 million yuan compared with the same period last year, an increase of 152 yuan year-on-year60% to 20332%。It is expected that the net profit attributable to shareholders of listed companies after deducting non-recurring gains and losses will be 4.5 million yuan to 6.5 million yuan in 2023, a decrease of 2.42 million yuan to 420,000 yuan compared with the same period last year, a year-on-year decrease of 3497% to 607%。
The main reason for the expected increase in the performance of the current period is the impact of non-operating profit and loss, in view of the fact that the company's real estate located at No. 101, Huangjiao Road, Huangyan District, Taizhou City was expropriated, and the asset disposal income generated by the compensation involved in this expropriation has a positive impact on the company's 2023 annual results.
5. Haiyou New Materials: 2023 annual performance forecast
According to the preliminary calculation of the company's financial department, Haiyou New Materials is expected to achieve operating income of 480,000 in 2023000,000 to 500,000000,000 yuan.
