"Over the last couple of years, Supermicro has been continuing our mission of becoming a strong global leader of server and storage solutions, especially the greenest and best TCO IT solutions. We have added many new product lines and dramatically increased our operational capacity worldwide.

"We are the only server and storage solution provider with more than half of our engineering, product development and final assembly based in the USA. Our engineering and R&D strengths allow us to quickly deliver the most advanced technology with the broadest range of server and storage products in our industry. We are very excited by our product solutions targeting Artificial Intelligence, 5G / Edge, and the evolving needs of the Enterprise, which offer our company a substantial growth opportunity in a $100B market."
