Nidec Corporation is navigating a deepening crisis following the disclosure of over ¥1.1 trillion ($6.9 billion) in accounting-related write-downs and charges. The company’s stock plunged as much as 19.8% on October 1, 2026, after its auditor, PricewaterhouseCoopers (PwC), issued a disclaimer of opinion on the firm's annual securities report for the fiscal year ended March 2026.
This withholding of an auditor's opinion is a severe development in Japan’s regulatory environment. According to accounting experts, this represents a significant negative factor in the Tokyo Stock Exchange’s (TSE) review process, placing Nidec at a realistic risk of delisting. PwC clarified that the decision was due to a lack of necessary information during a complicated financial investigation, rather than specific allegations of management wrongdoing, though the company’s internal controls remain under intense scrutiny.
Following the departure of President Mitsuya Kishida—reportedly linked to inappropriate remarks regarding financial reporting—the company has appointed Michio Kaida to steer a new business plan. Nidec aims to pivot toward artificial intelligence, power generation, and energy storage sectors to restore investor confidence. However, the Forensic Ledger notes that leadership transitions in the shadow of an accounting fraud often struggle to regain market trust when the auditor's opinion remains disclaimed. As activist investors circle the firm, the primary challenge remains reconciling the accounting irregularities uncovered by the third-party committee—which amounted to ¥160.7 billion in cumulative profit inflation from 2021 to 2025—with the company's future operational viability.
