AI Infrastructure Expansion Supports Business Momentum

Gross margin improved to 9.9% during the quarter from 6.3% in the previous quarter. Non-GAAP gross margin also reached 10.1%, improving from 9.7% reported during the same period last year. The stronger margins reflected improved operational efficiency and higher demand for AI-related products.

Supermicro ended the quarter with $1.3 billion in cash and cash equivalents. However, total bank debt and convertible notes reached $8.8 billion during the same period. Despite higher debt levels, expanding AI infrastructure demand continued supporting the company’s growth outlook.
