In reporting its fourth-quarter earnings, Applied Materials (AMAT) announced net sales within its Energy & Environmental Services (EES) segment (which includes PV tool revenues) of US$606 million. Accordingly, Solarbuzz equipment supplier analysis reveals that AMAT has just reached a significant landmark: the first equipment supplier to reach and exceed the US$1 billion barrier for PV-specific trended ttm tool revenues. Certainly, this achievement offers comfort to tool suppliers that the PV segment has grown to an appreciable level. However, while every other PV tool supplier would welcome reaching this milestone, AMAT’s road taken to the US$1 billion PV revenue mark has been far from incident free.
