1103 ET - Nebius Group's Chief Executive Arkady Volozh says customer prepayments are becoming the standard structure of its agreements, helping the company get its capital back faster. For agreements in the third quarter, prepayments covered 100% of the company's associated spending plans, including data center construction and networking. That's up from a 50% to 60% share in the second quarter, he says. As a result, payback in the third quarter shortened to one year and seven months, from one year and 10 months, he says.
