1. Qualitative information regarding financial results for the nine months ended
February 28, 2021
(1) Explanation of operating results
During the nine months ended February 28, 2021, the Japanese economy continued to face challenging
circumstances due to the impact of the novel coronavirus disease (COVID-19), yet production, exports
and other areas have been showing improvement as economic activity has resumed.
Despite the trend of recovery in capital investment among semiconductor-related companies, primaryusers of the products of MIMASU SEMICONDUCTOR INDUSTRY CO., LTD. (the “Company”),
investment momentum overall remained sluggish, reflecting a cautious stance. On the other hand,rising demand for semiconductor devices gave rise to steady production of semiconductor siliconwafers despite the COVID-19 pandemic.
Amid such business environment, the Company engaged in concerted efforts to improve its operating
results, which entailed striking a balance between promoting its cutting-edge processing technologies
and lowering costs, while also actively proceeding to promote sales of products developed in-house.
As a result, although net sales for the nine months ended February 28, 2021 decreased by 7.5% year onyear to ¥63,678 million, operating profit was ¥4,856 million (up 1.2% year on year), ordinary profit
was ¥4,813 million (up 6.3%), and profit was ¥3,296 million (up 5.8%).
Semiconductor Division
In this division, production was steady mainly for 300-millimeter wafers (including reclaimed wafers).
Under these circumstances, we have further promoted quality improvement and cost reduction.
Industrial Sales Division
In this division, we actively engaged in sales promotions of products developed in-house and otherproducts handled by the division. However, sales for both products decreased.
Engineering DivisionThis division specifically assumes the role of development and as such has been actively developing inhouse products and selling them through the Industrial Sales Division.
In addition, the division has been actively engaged in developing, designing and manufacturing devices
for use in the Semiconductor Division.
(2) Explanation of financial position
Total assets as of February 28, 2021 were ¥90,229 million, down ¥11,347 million from the end of theprevious fiscal year, mainly reflecting a decrease in property, plant and equipment. Total liabilities were¥24,388 million, down ¥13,646 million, mainly reflecting a decrease in trade payables. Total net assets
were ¥65,840 million, mainly reflecting an increase of ¥2,268 million in retained earnings.
(3) Explanation of earnings forecasts and other forward-looking statements
The earnings forecasts have not been changed from those announced on December 24, 2020.
