| Focusing on Offshore Oil and Gas Equipment, Deepening “AI + Oil & Gas” Integration, and Injecting New Momentum for Sustainable Development

The proceeds from this private placement will be invested in high-end offshore oil and gas equipment and AI-powered digital oilfield services:

First, Shenkai will further enhance its R&D and manufacturing capabilities in deepwater oil and gas equipment, actively responding to the national strategy for domestic substitution. Key development areas include unmanned and intelligent integrated wellhead equipment and control systems, as well as fast logging equipment suitable for deepwater exploration. These efforts will continuously improve product innovation and manufacturing technologies, providing robust equipment support for overcoming international technical barriers and ensuring the independent development of China’s deepwater resources.

Second, through the strategic acquisition of BOET, Shenkai will leverage its technological strengths and resource advantages in AI-driven digital solutions for the oil and gas industry. By deeply integrating these capabilities with Shenkai’s existing survey, measurement, logging, and guidance systems, Shenkai aims to build digital intelligent wellsite solutions centered on “Survey–Measurement–Logging–Guidance–Drilling + AI Core.” This will establish a complete closed loop of “hardware equipment + AI-assisted decision-making + engineering services,” driving Shenkai’s business model transformation from an “oilfield equipment supplier” to a “comprehensive digital intelligent wellsite solutions provider,” and securing a first-mover advantage in the industry’s digital and intelligent transformation.

While delivering solid returns for all investors, the private placement investment projects also serve as a key foundation for Shenkai’s future industrial upgrading. They align with the national priorities of the 15th Five-Year Plan and will further consolidate and enhance Shenkai’s core competitiveness in the fields of energy equipment and engineering services.
