LPTH makes optical sensors with a specialty in molded optics The bullish case involves expanded markets in autonomous vehicles, 5G & IOT. 12-month backlog has increased 38% Consensus "expected" Rev increase for 2019 = ~18% 12% of Revs come from telecom sector and this should increase in H2/19 as the 5G roll out progresses beyond pilot cities. 5G applications for LPTH's molded optics business is a high margin portion of their business OTOH, 28% of Revs come from 3 customers. Loss of one these customers would be devastating (OCLR is a competitor) Patent position outside of molded optics is mediocre.
