Emerson, which said last June it would seek to spin off the network power business and explore options for its remaining non-core portfolio, is also talking with private equity firms about pursuing a transaction, including Platinum Equity LLC, the people added. Other companies have also expressed interest, according to the people. There is no certainty over which course of action Emerson will pursue and no deal is likely until later this year, the people said, asking not to be identified because the negotiations are confidential. Siemens did not respond to a request for comment, while Emerson and Platinum Equity declined to comment. The remaining non-core portfolio that Emerson has been looking to sell includes its motors and drives, power generation and remaining storage businesses. Collectively, these assets generate around US$200 million in annual earnings before interest, taxes, depreciation and amortisation, sources have previously told Reuters.
