The fallout from Nidec Corporation’s protracted accounting scandal continues to draw scrutiny from activist short sellers. Carson Block, founder of Muddy Waters Capital, recently indicated that the external investigations conducted into the motor manufacturer’s financial practices likely missed critical periods of misconduct. Block, who first flagged Nidec’s aggressive accounting and questionable corporate governance in 2016, argues that the recent probe—which focused on fiscal 2020 through early 2025—fails to account for years of underlying issues that were evident long before the current investigation began. Nidec has faced significant turmoil, including the recording of 632 billion yen (approximately $4 billion) in write-downs and the placement of its shares under special supervision by the Tokyo Stock Exchange in October 2025. Since that regulatory intervention, the company’s market value has eroded by over 30%, leaving the stock trading near decade-long lows. While Nidec maintains that earlier periods were analyzed where necessary, the lack of a clean audit opinion remains a primary catalyst for investor anxiety. The situation highlights a recurring theme in Japanese corporate governance: a cultural aversion to conflict that often delays necessary transparency, complicating the efforts of activist investors to force meaningful reform. As the company struggles to regain its footing, the discrepancy between the scope of the official investigation and the historical concerns raised by short sellers suggests that the true extent of Nidec’s financial liabilities may remain obscured. ## Key Takeaways - Carson Block contends that recent Nidec investigations failed to address the full historical timeline of the company's accounting issues. - Nidec has recorded $4 billion in write-downs following the discovery of fraudulent activities at several subsidiaries. - The company remains under special supervision by the Tokyo Stock Exchange, with shares down over 30% since October 2025. ## Sources - Carson Block expects further fallout from Nidec scandal — UA.NEWS, November 5, 2026.
