Nidec may sue its own executives as 9% holder Oasis Management pushes a sale before an October 28 filing

Nidec has received the report on whether its own executives are liable for its accounting fraud and says it may sue them for damages. What its AI-cooling franchise is worth has stopped being a technology question: a delisting decision due October 28, and a 9% activist pressing for a sale, will set the price.

Shigenobu Nagamori, Nidec's founder and until this week its largest shareholder, meeting Prime Minister Narendra Modi in New Delhi in 2015. Oasis Management has now overtaken him as the company's biggest holder.

Nidec can now sue its own leadership. The Kyoto motor maker said on October 15 that it had received the report of a committee set up in March to decide whether current and former directors, auditors and vice presidents bear legal liability for the group's improper accounting, and that it will weigh claims for damages against them 27. The next morning UBS cut the stock to Neutral and the shares fell more than 9% 1. The underlying business is an AI-infrastructure franchise in working order; the discount on it is a trust discount, and a filing due October 28 decides how it resolves.

The engineering is ready; the accounts are not

Nidec, the world's largest maker of precision motors, spent this week's OCP Global Summit showing a 3.2-megawatt in-row coolant distribution unit for high-density AI clusters, built for 800-volt DC data-center power, with mass production planned for the first half of 2027 5. Its new chief executive, Michio Kaida, is shifting resources out of appliances and cars into energy infrastructure, AI products and semiconductors 8. But for the year ended March 2026 the company wrote down more than ¥600 billion after accounting fraud at subsidiaries in Italy, Switzerland and China, erasing practically all of the profit it had earned over the past decade, and PwC Japan has refused to vouch for its financial statements 8116.

October 28 is the gate

The Tokyo Stock Exchange put Nidec on special alert a year ago. The company must now file a securities report carrying an auditor's opinion by October 28; a missed deadline starts a delisting review, and the exchange may grant only until March 118. Suing executives is accountability, but a damages fight also extends the very overhang the listing needs lifted.

The 9 percent shareholder wants the sale run first

Oasis Management has raised its stake to 9.0%, passing founder Shigenobu Nagamori's 8.3% to become the largest holder 410. Seth Fischer wants the board to hire advisers and solicit preliminary bids now, before the exchange rules, because a delisting would strand minority shareholders 1011. Analysts expect buyers to do the opposite and wait for that ruling, so they can bid at a discount 11.

The AI buildout will pay whoever ends up holding these assets with clean books. Nidec shows where the bottleneck in AI infrastructure can sit: the cooling unit ships in 2027, but the audit opinion is due October 28.
