On March 30, 2026, OMRON Corporation, the Japanese industrial automation giant, officially announced the sale of its core electronic components business—the Device & Module Solutions (DMB) division—to Carlyle, a leading U.S.-based alternative asset management firm. The transaction is valued at approximately 81 billion yen.

This decision was not made abruptly. As early as September 2025, OMRON's Board of Directors had approved the divestiture plan and announced its intention to complete the separation of the DMB business by April 2026. Following six months of strategic evaluation and negotiations, the company ultimately determined to achieve operational independence for the business through a controlling stake sale.

Historical Origins and Business Value

DMB represents OMRON's founding business, with its history tracing back to the company's establishment in 1933. OMRON originally started by manufacturing X-ray timers for medical equipment and subsequently expanded its product portfolio to encompass precision electronic components such as relays, switches, sensors, and connectors. These high-reliability devices have not only enabled the automation of social infrastructure—including automated ticket gate systems—but have also served as the technological foundation for OMRON's industrial automation control equipment, playing a fundamental and pivotal role in the Group's value creation system.

Although the business generated revenue of 105.4 billion yen in fiscal year 2024, accounting for 13% of the Group's total sales, OMRON determined that more aggressive strategic adjustments were necessary amid the profound transformations in the global industrial landscape.

Intensifying Competition and Resource Reallocation

The primary factor driving OMRON's decision is the increasingly competitive market environment. While the rapid growth of the electric vehicle industry has triggered explosive demand for high-capacity relays and other products, competitive pressure from new entrants—including Chinese domestic manufacturers—has continued to escalate, fundamentally reshaping the industry landscape.

In its announcement, OMRON stated that despite progress in operational efficiency improvements through preliminary divestiture preparations, "the current business environment requires faster and larger-scale investments than anticipated" to maintain competitiveness. Transferring DMB to Carlyle will not only create an optimal growth environment for the business and provide greater flexibility in capital operations, but will also enable OMRON itself to concentrate resources on its core Industrial Automation (IA) business and data services domain.

Transaction Structure and Subsequent Arrangements

The transaction will be executed through a phased implementation approach:

Phase One (July 1, 2026): OMRON Devices Corporation, a subsidiary of the OMRON Group, will acquire the DMB business through an absorption-type merger, simultaneously consolidating related shares and assets held by the Group across various countries and regions. Upon completion of the merger, the company will be renamed "Aratas."

Phase Two (October 1, 2026): All shares of OMRON Devices will be transferred to a wholly-owned subsidiary of "TCG2601," a special purpose company established by Carlyle.

Notably, following the transaction's completion, OMRON plans to make a minority equity investment in the aforementioned special purpose company, maintaining a 5% ownership stake. This arrangement is designed to preserve sales cooperation opportunities with the successor company while supporting the business's smooth transition to a new operational structure as an independent entity.
