I-VI Incorporated (IIVI) announced last Friday that it obtained antitrust clearance from the State Administration for Market Regulation of the People's Republic of China for the acquisition of Finisar (FNSR), and one condition is that II-VI and Finisar will separately operate the wavelength selective switch) business for three years, B. Riley FBR analyst Dave Kang tells investors in a research note. This is a positive for Lumentum (LITE) since the condition will limit the combined company's ability to join forces to close the gap, says the analyst, who believes Lumentum has a three-year lead in the high-end WSS segment. The analyst maintains a Buy rating on Lumentum and Neutral rating on II-VI.
