$AEHR has not disclosed the name. Alphabet ($GOOGL) is the strongest circumstantial fit based on TPU product timing, training-and-inference workloads and Ironwood's dual-chiplet architecture. Amazon ($AMZN) is also plausible because the initial Sonoma order closely preceded the Trainium2 production ramp.
No. Neither Alphabet ($GOOGL), Google Cloud ($GOOGL), $AEHR nor a manufacturing partner has confirmed that Google ($GOOGL) TPUs use Sonoma systems. The connection is an inference from public clues.
Yes. Trainium2's December 2024 launch matches the initial $AEHR system timeline, and AWS uses Trainium for training and inference at enormous scale. The weakness is that Trainium3 was already generally available before $AEHR announced its next-generation production win.
It helps investors independently track processor volumes, delays, capital spending and generation changes. Because the customer is unnamed, investors must instead rely on $AEHR's order announcements and management commentary, increasing information and concentration risk.
