As disclosed in our press release dated September 19, 2025 titled "Notice Regarding Commencement of Considerations to Spin Off the OMRON Device & Module Solutions Business," OMRON Corporation ("Company") has been discussing a spin-off of the business operated by the Device & Module Solutions Company ("DMB"). At the Board of Directors meeting held today, the Company resolved to transfer DMB to OMRON Devices Co., Ltd, a subsidiary of the Company, ("Succeeding Company"), through an absorption-type company split ("Absorption-Type Company Split"), to execute the transfer, within the OMRON Group ("Group"), of shares and assets related to this business currently held by Group companies in countries and regions worldwide ("Intra-Group Reorganization"), and to transfer all shares of the Succeeding Company to TCG2602 Co., Ltd. ("SPC #2"), a wholly owned subsidiary of TCG2601 Co., Ltd. ("SPC #1"), which has been established by The Carlyle Group (including its affiliate companies and other related entities, "Carlyle") ("Share Transfer"). The Company hereby announces that, effective today, it has concluded an absorption-type company split agreement with the Succeeding Company and a share transfer agreement with SPC #2 as described below.

In this Absorption-Type Company Split, the shares and assets related to DMB currently held by the Company will be transferred to the Succeeding Company. Additionally, the shares, equity interests, and assets related to DMB currently held by Group companies in various countries and regions worldwide are also to be transferred to the Succeeding Company or to overseas subsidiaries to be newly established by the Succeeding Company ("Overseas Succeeding Companies"). Meanwhile, in the Share Transfer, the Company will transfer all of the issued shares of the Succeeding Company to SPC #2. Of the series of transactions (collectively the "Transaction,"), the Absorption-Type Company Split will take effect on July 1, 2026, and the Share Transfer will be carried out on October 1, 2026, subject to the completion of any required clearances, approvals, and authorizations under competition laws and other applicable laws and regulations in Japan and abroad.

After the execution of the Share Transfer, the Company plans to take a stake in SPC #1 so that its shareholding ratio will be 5% ("Equity Investment"), as described in "II. Summary of the Transaction" below.
The name of the Succeeding Company will be changed to Aratas Corporation after the Absorption-Type Company Split takes effect.

Please note that, as the Absorption-Type Company Split is a simplified absorption-type company split involving the Company and the Succeeding Company, a subsidiary of the Company, some of its disclosure items and details have been omitted from this release.

I. Objectives of the Transaction

DMB is the Company's founding business, which began in 1933 with the manufacture of "timers for taking X‑ray photographs" for medical applications, and has accumulated related technologies in relay, switches, sensors, and other devices. These high-quality devices have contributed to the development of a variety of industries, providing element technologies that support the practical implementation of social systems, such as unmanned automated station systems equipped with automated ticket gates, and forming the foundation of the Industrial Automation Business, with industrial equipment at its core, thereby playing a key role in the technology platform that underpins the Group's value creation.

DMB has since achieved steady growth over a long term, but is now facing significant changes in its business environment. While the high-capacity relay market is expanding rapidly as end products become increasingly environmentally friendly, with electric vehicles (EVs) as a prime example, new players--notably local Chinese competitors--are emerging. This requires us to make business decisions with greater speed and to further expand investment if we are to outpace them and be the first to capture market opportunities. Given these changes in the external environment, as we announced in September 2025 in the "Notice Regarding Commencement of Considerations to Spin Off the OMRON Device & Module Solutions Business," the Company has been engaging in discussions on how we can build an autonomous business operation system and ensure sustainable growth for DMB, including through potential partnerships with external parties. Although the spin-off of DMB is expected to enhance decision-making speed, we have also recognized the need to make investments more promptly and on a larger scale than initially anticipated, which has led us to the conclusion that it would be optimal to sell DMB to Carlyle. This will not only create the optimal growth environment for DMB, but will also enable our company to further concentrate investments to accelerate the business portfolio restructuring set out in the "Medium Term Roadmap SF 2nd Stage" announced in November 2025 - namely, to expand the 13 focus businesses centered on IA (Industrial Automation) across the Device business and the Data Service business.

Since opening its Tokyo office in 2000, Carlyle has continuously expanded its operations in the Japanese market, accumulating extensive experience and expertise through numerous successful investments in Japan, thereby demonstrating a long-term commitment to the Japanese market. Carlyle has deep industrials expertise and supports businesses in this sector from strategy development through execution, including international expansion and the strengthening of business foundations and operations. In light of this, the Company has concluded that Carlyle is the right partner for DMB's business expansion after the spin-off.

After the Share Transfer, the Company plans to take a stake in SPC #1 so that its shareholding ratio will be 5%. By doing so, the Company will support the Succeeding Company's steady switchover to a new process as an independent company, while appropriately ensuring opportunities for the Succeeding Company and Group companies to collaborate in sales activities.

II. Overview of the Transaction

Under the Transaction, the Company will transfer the shares and assets related to DMB currently held by the Company to the Succeeding Company by means of the Absorption-Type Company Split, effective July 1, 2026 (subject to change). The Company will also transfer the shares, equity interests, and assets related to DMB currently held by its Group companies in countries and regions worldwide to either the Succeeding Company or Overseas Succeeding Companies by means of share or equity transfers, asset transfers, business transfers, or other similar methods. Please note that the Company aims to implement the Intra-Group Reorganization at the time close to the effective date of the Absorption-Type Company Split, to the extent practicable; however, depending on the progress in preparations for such transfers and the status of necessary procedures in each country or region, the Intra-Group Reorganization may be implemented at the time different from the effective date of the Absorption-Type Company Split in certain countries and regions.

With the above in mind, the Company will transfer all issued shares of the Succeeding Company to SPC #2 on October 1, 2026 (subject to change).

The Company plans to invest in SPC #1 to be held by Carlyle following the Share Transfer, as a result of which the Company will indirectly hold a 5% interest in the Succeeding Company.
