Management's Report on Internal Control

NOTE TO READERS:

The following is an English translation of the management's report on internal control over financial reporting ("ICFR") filed under the Financial Instruments and Exchange Act of Japan. This report is presented merely as supplemental information. There are differences between an assessment of ICFR under the Financial Instruments and Exchange Act ("ICFR under FIEA") and one conducted under the standards of the Public Company Accounting Oversight Board (United States) ("ICFR under PCAOB");

• In an assessment of ICFR under FIEA, there is detailed guidance on the scope of an assessment of ICFR, such as quantitative guidance on business location selection and/or account selection. In an assessment of ICFR under PCAOB, there is no such detailed guidance. Accordingly, regarding the scope of assessment of internal control over business processes, we selected locations and business units to be tested based on annual consolidated net sales (after the elimination of transactions between consolidated companies) and consolidated total assets (after the elimination of transactions between consolidated companies) , and selected the companies with net sales and total assets of approximately two-thirds of the total amount on a consolidation basis as "significant locations and/or business units." At selected significant locations and/or business units targeted for assessment, our scope of assessment included business processes leading to sales, accounts receivable and inventories as significant accounts that may have a material impact on our business objectives. Further, in addition to selected significant locations and/or business units, we also included in the scope of assessment, as business processes having greater materiality, business processes relating to (i) greater likelihood of material misstatements and/or (ii) significant accounts involving estimates and the management's judgment and/or (iii) a business or operation dealing with high-risk transactions, taking into account their impact on the financial reporting.

1. Matters relating to the basic framework for internal control over financial reporting

Junta Tsujinaga, Representative Director, President and CEO, and Seiji Takeda, Managing Executive Officer, CFO are responsible for designing and operating effective internal control over financial reporting of OMRON Corporation (the "Company") and have designed and operated internal control over financial reporting in accordance with the basic framework for internal control set forth in "The Revision of Standards and Practice Standards for Management Assessment and Audit Concerning Internal Control Over Financial Reporting (Council Opinion)" released by the Business Accounting Council.

The internal control is designed to achieve its objectives to the extent reasonable through the effective function and combination of its basic elements. Therefore, there is a possibility that misstatements may not be completely prevented or detected by internal control over financial reporting.

2. Matters relating to the scope of assessment, the basis date of assessment and the assessment procedures

The assessment of internal control over financial reporting was performed as of March 31, 2023 which is the end of this fiscal year. The assessment was performed in accordance with assessment standards for internal control over financial reporting generally accepted in Japan.

In conducting this assessment, we evaluated internal controls which may have a material effect on our entire financial reporting on a consolidation basis ("entity-level controls") and based on the results of this assessment, we selected business processes to be tested. We analyzed these selected business processes, identified key controls that may have a material impact on the reliability of the Company's financial reporting, and assessed the design and operation of these key controls. These procedures have allowed us to evaluate the effectiveness of the internal controls of the Company.

We determined the required scope of assessment of internal control over financial reporting for the Company, as well as its consolidated subsidiaries and equity-method affiliated companies, from the perspective of the materiality that may affect the reliability of their financial reporting. The materiality that may affect the reliability of the financial reporting is determined by taking into account the materiality of quantitative and qualitative impacts on financial reporting. In light of the results of assessment of entity-level controls conducted for the Company and its consolidated subsidiaries, we reasonably determined the scope of assessment of internal controls over business processes. Consolidated subsidiaries and equity-method affiliated companies determined to have an insignificant quantitative and qualitative influence on the reliability of financial reporting are not included in the scope of assessment of entity-level controls.

Regarding the scope of assessment of internal control over business processes, we selected locations and business units to be tested based on the previous year's consolidated net sales (after the elimination of transactions between consolidated companies) and consolidated total assets (after the elimination of transactions between consolidated companies) , and selected the companies with net sales and total assets of approximately two-thirds of the total amount on a consolidated basis as "significant locations and/or business units." At selected significant locations and/or business units targeted for assessment, our scope of assessment included business processes leading to sales, accounts receivable and inventories as significant accounts that may have a material impact on the business objectives of the Company. Further, in addition to selected significant locations and/or business units, we also included in the scope of assessment, as business processes having greater materiality, business processes relating to (i) greater likelihood of material misstatements and/or (ii) significant accounts involving estimates and the management's judgment and/or (iii) a business or operation dealing with high-risk transactions, taking into account their impact on the financial reporting.

3. Matters relating to the results of the assessment

The above assessments determined that the Company's internal control over financial reporting was effective as of the last day of the fiscal year under review.
