Japan push: The loan deepens STT GDC's local platform in one of Japan's established data centre markets. "The Tokyo campus is central to our long-term commitment to Japan," said Kiyoshi Maeda, chief executive officer for Japan, pointing to growing cloud, AI, and digital infrastructure demand.
The signal: The round ranks among the larger debt deals in its sector and region, sitting in the 91st percentile of all-time energy debt rounds tied to Singapore.
