IHI Corp reported on Tuesday that its consolidated subsidiary, IHI Aerospace, has been suspended from taking part in competitive bidding run by the Japan Aerospace Exploration Agency, with the suspension effective from June 2 and lasting five months.
The action follows findings that the aerospace unit filed reports indicating certain contracted tasks had been completed when, in fact, portions of that work remained outstanding. IHI said the discrepancy led to costs being claimed on government contracts based on reports that did not accurately reflect the actual status of the work.
Market reaction was immediate. Tokyo-listed IHI shares fell as much as 7% to 2,411.0 yen, marking their lowest level since September 2025.
According to the company, the irregularities concerned contracts tied to maintenance of equipment used in the manufacture of space-related hardware and the procurement of components. An internal probe that examined 438 contracts going back to fiscal 2016 identified similar reporting problems in 14 contracts in total - 13 related to equipment maintenance and one linked to component procurement.
IHI said it informed JAXA of the matter in December 2025 and has continued to cooperate with the agency's investigation. The firm also reported that inspections performed by an independent quality assurance department did not find any impact on product quality or on the assembly of final products.
On the financial front, IHI stated it is evaluating the potential consequences for earnings and will disclose any material effects should they arise. The company has not announced any confirmed financial impact as of the statement.
Context summary - The suspension restricts IHI Aerospace from bidding on JAXA competitive contracts for a five-month period starting June 2. The issue stems from cost claims made on the basis of reports that did not reflect incomplete work. An internal review covering hundreds of contracts found a small number with similar problems. Independent inspections found no effect on product quality, and the company is assessing earnings implications.
Market reaction - Shares of IHI declined sharply following the disclosure, dropping up to 7% intraday to 2,411.0 yen.
Company actions - IHI reported the issue to JAXA in December 2025, has cooperated with the agency's probe, conducted an internal investigation covering 438 contracts, and carried out independent quality assurance inspections.
Note: The company has indicated it will disclose any material earnings impact if necessary.
