Omron said on 1 October 2026 that it has completed the sale of Aratas, the company that now holds its device and module solutions business, to a wholly owned subsidiary of a company set up by The Carlyle Group, and that it has made its planned 5% investment in the buyer's parent.
What closed today
The business, which Omron calls DMB and which was run by its Device & Module Solutions Company, moved into Aratas through an absorption-type split that took effect on 1 July 2026. That step was already done. Today's closing is the transfer of all of Aratas's issued shares to TCG2602, a wholly owned subsidiary of a company set up by The Carlyle Group (including affiliates and related entities). The notice says both steps went ahead as planned, following Omron's announcement of 30 March 2026.
Where Omron's 5% sits
Omron does not hold 5% of Aratas. The notice's company overview lists TCG2602 as holding 100% of Aratas. Omron has instead invested in TCG2601, the parent of TCG2602, so that its voting-rights holding ratio in that parent is 5%. That investment was also completed today.
Aratas at a glance
Aratas is based in Kyoto, has capital of ¥1bn and a March 31 year end. Its business is described as the manufacture and sale of electronic components and electrical machinery. The notice does not give a transaction price. On future disclosures, Omron says only that it will report promptly anything that arises.
