destination (nationally or internationally) as specified by the smartphone brand. Likewise, the EMS providers do not have the discretion to decide which component suppliers it will procure required components from, since this decision lies with the smartphone brand for whom the EMS provider manufactures the phones. Further, the smartphone brands avail of the services of third-party EMS providers only if they deem it commercially prudent as opposed to captively manufacture the components or assemble the smartphone in-house. And, even when the smartphone brand chooses to outsource the assembling of phone to an EMS provider, it outsources to multiple EMS providers, instead of going through a single contract manufacturer. Therefore, the addressable market for EMS providers is limited to the extent the smartphone brands decide to outsource their manufacturing requirement, which also can be multi-sourced through available EMS service providers. For the foregoing reasons, the ability of players in the smartphone manufacturing value chain seems to be rather constrained.
