AEHR had a tough 2018, mostly based on order delays. AAPL chose AEHR's flash testing equipment over TER & FORM in 2017 due to technological edge. AEHR technology allows testing at the wafer level, while competitors testing equipment cannot be used until the memory module is packaged. 10/18 earnings report was hurt by earnings delays. Cash flow position is dangerous and 1/19 earnings results are not certain.
