Kumamoto earthquake (2): Impacts minor for semiconductor cluster,

only Renesas has confirmed some damage to equipment

CITI'S TAKE

We have been monitoring earthquake-related company updates and

media reports through the evening of July 29. At present, no large-scale

equipment damage or situations likely to lead to long-term suspensions Masahiro ShibanoAC

like those from the 2016 Kumamoto earthquake have been confirmed. For +81-3-6776-4641

example, Tokyo Electron, Mitsubishi Electric, Horiba, and Sony report no masahiro.shibano@citi.com

human casualties or major building damage. Meanwhile, Renesas Arifumi Yoshida

apparently confirmed minor equipment damage at its Kawajiri and Nishiki +81-3-6776-4610

plants, but its clean rooms appear intact. As outlined in yesterday's arifumi.yoshida@citi.com
