Reading guide
Robin notes Appier’s planned March 31, 2021 listing on Japan’s Mothers market, under stock code 4180. Its prospectus was in Japanese. He shared several images that he himself guessed were balance sheets and income statements, with units he guessed were thousands of yen, and included the Japanese and English Japan Exchange Group links. His personal view was that one could certainly buy Appier in Japan, but those choosing to keep their capital in Taiwan, especially if they could not read Japanese, could pay closer attention to 91APP. This is a historical observation and personal view, not investment advice.
