Second Quarter 2026 Operational Highlights

“We achieved robust growth across our key financial and operational metrics in the second quarter of 2026, as our execution capabilities and high-quality deliveries continued to attract new orders,” said Josh Sheng Chen, Founder, Executive Chairperson of VNET. “We secured a 345MW wholesale order from a leading cloud service provider in the second quarter, bringing our total wholesale order wins to 862MW year-to-date. Meanwhile, we continued to expand our strategic resource reserves, securing approximately 1.4GW of land bank capacity during the second quarter, including 908MW in the Chinese mainland and 478MW overseas. This increased our total capacity to over 4GW, providing a clear, multi-year growth runway across both domestic and international markets.

“In addition, we deepened our collaboration with Contemporary Amperex Technology Co., Limited and signed a strategic cooperation agreement to jointly develop a three-layer integrated compute-energy ecosystem comprising gigawatt-scale compute-energy facilities, distributed compute-energy networks, and a zero-carbon token ecosystem. By combining our complementary strengths and deepening cooperation across technology, infrastructure and supply chains, we will jointly advance innovation in integrated compute-energy systems. Together, we aim to contribute to the next generation of digital energy infrastructure in the intelligent era.”

Peter Zhihua Zhang, Senior Vice President, Operational Finance of VNET, commented, “In the second quarter, our total net revenues increased by 14.2% year-over-year to RMB2.78 billion, mainly driven by 29.3% year-over-year growth in wholesale revenues. Wholesale revenues once again surpassed retail, increasing wholesale’s contribution to 39.8% of our total net revenues and reinforcing its position as our primary growth engine. Strong order momentum, long-term customer commitments and our well-paced delivery roadmap strengthen the visibility into our future revenue growth. Adjusted EBITDA increased by 25.4% year-over-year to RMB918.3 million, with its margin expanding by 3.0 percentage points to 33.0%. Moving forward, we will remain focused on disciplined execution across delivery, capacity expansion and capital allocation, driving high-quality growth and creating value for our shareholders.”
