Ten years after Muddy Waters Capital first targeted Nidec Corp. for aggressive accounting and questionable corporate governance, the motor manufacturer finds itself at the center of a massive financial scandal. The company, which has failed to secure an auditor’s opinion on its financial statements, now faces the threat of delisting from the Tokyo Stock Exchange. For Carson Block, the current crisis is not merely a recent failure but a validation of long-standing concerns that were ignored by the market for years.
Nidec recently disclosed ¥632 billion (approximately $4 billion) in write-downs for the fiscal year ended March 31, 2026. While the company’s internal investigation covered the period from fiscal 2020 through the first quarter of 2025, Block argues that this scope is insufficient. By omitting the earlier years—specifically the period around 2016 when Muddy Waters first published its research—the investigation fails to address the root of the company’s cultural and governance dysfunction.
Block’s commentary highlights a broader frustration with the Japanese market’s resistance to transparency. He describes an "active conspiracy of silence" that protects problematic firms from accountability. With Nidec’s shares trading near decade-lows and the company under special supervision by the Tokyo Stock Exchange since October 2025, the situation serves as a case study in the limitations of Japan’s corporate reform agenda. For investors, the unresolved nature of these irregularities suggests that the full scale of Nidec’s financial misstatements may still be hidden, warranting extreme caution regarding the firm's remaining assets and future disclosures.
