Financial Results for the Third Quarter of Fiscal Year Ending March 2025

February 6, 2025

Summary of 3Q results

  • Net sales declined YoY due to decreased sales volumes of various products, including products for construction machinery and for automobiles, despite the start of mass production on a large-scale project in the strategic business of precision spring components.
  • Despite the effects of decreased sales volumes, operating income grew YoY due to contributions from the precision spring components and improvements in costs and selling prices.
  • Ordinary income and net income rose YoY due to various factors, including higher operating income and reduction of non-operating expenses, despite the recording of extraordinary losses on our withdrawal from the German springs business and litigation related to a North American subsidiary.

  • • Indonesia: Slow automobile sales due to tightening of loan approval process

  • Due to progress in margin improvements, operating income grew sharply despite decreased sales volumes. FY2024 3Q is significantly more profitable compared to FY2023 3Q because FY2023 3Q was heavily impacted by a sharp decrease in quantity and resulting decline in productivity.
  • Net sales declined due to decreased sales volumes for automobiles and for construction machinery.
  • Operating income returned to profitability due to contributions from the start of a large-scale project in precision spring components, improvements made in selling prices, and improved earnings at the North American subsidiary.
  • Due to further increases in orders, MSM plans additional investment in equipment for precision spring components.
  • Net sales increased due to sales volumes of precision castings.
  • Due to product mix, operating income remained almost unchanged YoY despite increasing sales volumes.
  • While net sales remained almost unchanged YoY, operating income

declined due to a product mix and other factors.

  • Orders in FY2024 are projected to12.2 billion yen. These orders contribute to the future income in FY 2025 and after.

Impact of non-operating income/loss and extraordinary income/loss

  • Non-operatingincome/loss improved due to the reduction of non-operating expenses such as the improvement in foreign exchange profit and loss.
  • Extraordinary income/loss worsened YoY due to the recording of losses related to litigation related to a North American subsidiary in the third quarter (See the next page for more information) as well as the withdrawal from the German springs business.

Litigation and recording of extraordinary loss on North American subsidiary

Summary and background of litigation

  • This issue emerged when our North American subsidiary MSSC received a demand for price revisions on parts supplied from AirBoss Flexible Products Co., its supplier.
  • While our claims were initially upheld, the court decision ultimately upheld the claims made by Flexible.

December 2019 MSSC received notice of a demand for price revisions on parts supplied from Flexible its supplier, indicating that the supply of parts would cease if the demand was not met.

February 2020 MSSC filed with a local court for a preliminary injunction to ensure continuing supply. In response, a preliminary injunction was issued to continue the supply of the products at the current price. Flexible appealed against the judgement upholding MSSC claims.

July 2023

The Supreme Court remanded the case to the Circuit Court, where it resumed.

December 2024 The Circuit Court for the State of Michigan ordered MSSC to pay the demanded price retroactively and to pay

  1. late payment charge.
    January 2025 MSSC appealed the decision.

Impact on profit/loss

  • As a result of the court decision, we recorded an extraordinary loss of 0.7 billion yen as provisions for losses on litigationin the third quarter.
  • we are proceeding to negotiate with customers on rising procurement costs and on covering price revisions and other resultsin preparation for the event that MSSC loses the lawsuit and obligations for payment arise.
  • The point at issue in this decision is retroactive payments. We have already reached agreement with Flexible and customers regarding current prices.
    ⇒ Accordingly, we do not expect this case to result in losses beyond those recorded at this time.

Full-year performance forecasts

  • Forecasts for net sales, operating income, and ordinary income remain unchanged from previous forecasts. Progress toward these results is proceeding largely as planned.
  • The forecast of net income also remain unchanged from previous forecasts due to proceeding to negotiate with customers on covering price revisions, despite the recording of losses related to litigation involving the North American subsidiary in the third quarter.

We project an exchange rate of $1 = JPY150 (unchanged from the initial forecast).

  • Progress toward operating income of 3Q result and 4Q projections is proceeding largely as planned. Operating income is projected to improve in 4Q compared to 3Q for the following reasons:
    • Conclusion of price negotiations, including retroactive prices, mainly in the Springs Business
    • The tendency for Machinery Business sales to cluster toward the end of the year
