According to the new delisting rules, there are four main situations in which the company is warned of delisting risks. One of them is that the company's net profit before and after deducting non-recurring gains and losses is negative, and if the operating income after deducting business income unrelated to the main business and transactions without commercial substance is less than 6,543.8 billion yuan, the company can be warned of delisting risk.

According to the annual report disclosed by Sinopec Oil Service, the company has suffered losses for two consecutive years. If it continues to lose money this year, Sinopec Oil Service may be ST. In addition, if the company is ST, it needs to pay attention to the reasons and specific measures, such as whether it can improve its operation and strengthen management to avoid being terminated from listing.

Therefore, it is suggested that investors should deeply understand the company's operating conditions, industry prospects and other factors when investing in stocks, and at the same time should abide by the principles of investment risk management and formulate reasonable investment plans and risk control measures.
