OESX confirmed as Microsoft AI data center lighting vendor
Author argues Orion Energy Systems received a second multimillion-dollar MPHL2 order from a Fortune 20 hyperscaler he identifies as Microsoft, three months after the first, confirming Orion as the lighting vendor for Microsoft's Fairwater AI data centers. He notes Microsoft has 15 more buildings approved at Mount Pleasant, implying a queue of orders worth $45-60M from one campus versus Orion's $86M total 2025 revenue. Catalysts include continued reorders and Microsoft's doubling AI infrastructure spend. Main risks are the unconfirmed customer identity and reliance on continued Microsoft buildout.
