0713 GMT - Heavy artificial-intelligence investment will likely weaken credit metrics for Chinese and U.S. hyperscalers, but capital buffers can ease the strain, Moody's Ratings analysts say. U.S. hyperscalers' free cash flow is set to drop 2026-2027 as capex outpaces cash flow from operations. Leverage pressure is set to intensify as firms like Meta, Alphabet and Oracle step up debt issuances. Chinese hyperscalers face similar issues. Capex-to-operating cash flow ratios are up significantly and several firms will likely turn FCF negative in 2026-2027 as AI infrastructure and chip-procurement accelerate. R&D, model and application costs are also weighing on operating cash flow. Still, both sides have big cash cushions that--along with revenue and Ebitda growth--let them absorb 12-24 months of elevated capex without significantly hurting credit quality.
