Changjiang Nengke replied to the inquiry letter: By 2025, the income from the three major oil companies will account for approximately 24%.

On July 2nd, Jiangneng Technology, known as the "invisible champion of electric desalination equipment" by the selling research institute, responded to the inquiries from the North Exchange regarding its 2025 annual report. Jiangneng Technology's main source of revenue comes from electric desalination and electric dewatering equipment, with its downstream customers mainly being oil and gas petrochemical companies. The North Exchange requested Jiangneng Technology to explain whether its cooperation with PetroChina, Sinopec, and CNOOC is stable, and if there have been any significant changes in the cooperation model. Jiangneng Technology stated that the growth in overseas revenue was due to the company seizing the opportunity of growing demand in overseas markets, increasing efforts to expand overseas markets, continuously gaining access to high-quality overseas customers, and the increase in overseas backlogs in 2024. In a stable overseas market environment and demand, with the company continuously expanding its overseas business, the growth in overseas revenue is sustainable. Jiangneng Technology's response indicated that in the fiscal years 2024 and 2025, the company's revenues from PetroChina, Sinopec, and CNOOC were approximately 170 million yuan and 70 million yuan respectively, accounting for 55.53% and 23.74% of the current operating income, with a slight decrease in revenue and percentage for the year 2025.
