On August 13, 2026, ST Telemedia Global Data Centres announced up to US$1.37 billion (MYR5.6 billion) in green financing for its Johor campus and described up to 166 MW of future campus IT capacity, compared with the earlier 120 MW development potential. The financing ceiling is not expenditure already drawn, and planned campus capacity is separate from the first 16 MW facility, STT Johor 1, which remains under construction. The operator's December 2025 factsheet targets Q2 2027 readiness for that first facility.
