Notice Regarding Difference Between Forecasted and Actual Performance

Asten Holdings Co., Ltd. (Headquarters: Chuo-ku, Tokyo; President and CEO: Satoshi Setoguchi; Securities Code: 8095) announces a discrepancy between the financial forecast previously disclosed on January 13, 2026, and the actual results announced today for the consolidated cumulative period of the second quarter (interim period) ending November 2026.

1. Difference Between Forecasted and Actual Consolidated Results for the Second Quarter (Interim Period) Ending November 2026

(Period: December 1, 2025 – May 31, 2026)

2. Reasons for the Difference Between Forecasted and Actual Consolidated Results

During the second quarter (interim period) consolidated cumulative period, sales revenue was generally in line with expectations. On the profit side, the chemical business, particularly the surface treatment chemicals division, contributed significantly to profits, exceeding forecasts. This was driven by increased investment in package substrate-related projects, spurred by the rapid expansion of the generative AI market.

Regarding performance from the third quarter onward, concerns remain about price trends and supply constraints in raw material procurement due to the situation in the Middle East. However, the specific impact is still under review. Therefore, the consolidated full-year forecast for the fiscal year ending November 2026 remains unchanged from the projection disclosed on January 13, 2026, in the 'Financial Results for the Fiscal Year Ended November 2025.'

*Forward-looking statements contained in this document, including performance forecasts, are based on information currently available to the company and on assumptions deemed reasonable. Actual results may differ significantly due to various future factors.
