Summary
Seth Fischer, founder and chief investment officer of Oasis Management, used the main stage at Sohn Tokyo 2026 to lay out a governance case against a family-run Japanese drugstore chain, which he did not name in the source material available to this summary. According to Fischer, the company granted stock options to its president and his brother at a price more than 99% below the plain option value calculated by its own valuation agent. He described the arrangement as a scheme for self-enrichment built on flawed valuations, a conveniently timed earnings downgrade and a weak board.
Fischer structured his presentation as a series of slides that built the argument before identifying the target. He pointed to a long-standing company, executive management that in his words "seems to have schemed for self-enrichment," a reliance on false valuations, and a weak board. He also noted that the company has been moved down from the Tokyo Stock Exchange's Prime section. His closing point was that under the right board and management, the company "will be far more valuable."
Oasis is now pursuing litigation against the brothers and others on the company's behalf, according to the source. Fischer asked that the brothers repay the options.
