Piper Jaffray analyst James Fish notes that the $660M acquisition of Luxterra announced by Cisco (CSCO) yesterday will have "mostly negative" impact on datacom focused optical transceiver suppliers Finisar (FNSR) and Applied Optoelectronics (AAOI). For the former, the analyst notes that Finisar generates about 75% of revenues from datacom transceivers and has frequently experienced Cisco as a 10% plus customer, adding that the vertical integration of the deal will diminishing Cisco's need for merchant transceivers. For the latter, the analyst notes that while Applied Optoelectronics does not "directly sell these components", the Luxterra deal shrinks its market and may lead to more aggressive price moves by the competitors. Fish also sees Fabrinet (FN) as a direct beneficiary of the Luxterra deal given its position as its contract manufacturer that stands to benefit "as Cisco ramps production of SiP transceivers."
