    • Aggressive UPS Line Conversion: Actively converting lines at the Ulsan facility to dedicated UPS battery production to preemptively capture accelerating demand in data center power solutions.

📝 Editor’s Comment (Perspective)

The analyst views Samsung SDI not merely as an indirect battery parts supplier through intermediary pack integrators, but as a strategic data center power solutions partner directly engaging global cloud service providers (CSPs) for multi-year procurement. This perspective emphasizes the structural transformation of earning power—driven by high-power BBU growth (+70% YoY market expansion in 2026) and proactive UPS capacity conversion at the Ulsan plant—over cyclical weakness in pure automotive EV cells.

To evaluate the ongoing validity of this investment thesis, key monitoring factors include the tangible execution of direct supply agreements with leading CSPs, market share expansion within the 2026 high-power BBU segment, and the operational ramp-up and margin delivery of the converted UPS lines at the Ulsan facility. These business developments can be tracked through upcoming quarterly financial announcements, company IR releases, and periodic regulatory filings.
