Subsequent Events [Abstract]
SUBSEQUENT EVENTS	SUBSEQUENT EVENTS On May 5, 2026, Flex announced its intention to separate its CPI segment from Flex and into an independent, publicly traded company (“SpinCo”). The separation of CPI into SpinCo will create a separate publicly traded company focused on data center power, digital infrastructure and power, thermal and compute integration. The spin-off of CPI from Flex is expected to be completed in the first quarter of calendar 2027 and is subject to the approval of Flex’s Board of Directors, shareholders, and the High Court of the Republic of Singapore and the SEC declaring SpinCo’s Form 10 registration statement effective. Subsequent to the spin-off of CPI from Flex, Flex will continue as an advanced manufacturing and supply chain solutions business consisting of its ITS and RMS segments. There can be no assurance that any separation transaction will ultimately occur or, if one does occur, of its terms or timing and there is no guarantee that the spin-off, if completed, will achieve the intended financial, strategic, and operational benefits. On May 1, 2026, the Company completed the business acquisition of 100% ownership of Electrical Power Products, Inc ("EPP"), a U.S. leader in critical power solutions for a total estimated purchase consideration of $1.1 billion of cash, subject to customary closing adjustments. The acquisition enhances the scale of the Company's U.S. critical power portfolio. EPP will be reported within the Power reporting unit in the CPI segment. Due to the timing of the EPP acquisition, it is not practical to disclose the preliminary allocations of the purchase consideration to the assets acquired and liabilities assumed. On April 30, 2026, the Company entered into, and fully drew down, a new $1.45 billion credit facility (the "New Credit Facility") which matures on the date that is 364 days after the date on which the term loans are first funded pursuant to the New Credit Facility. Proceeds from the New Credit Facility are to be used for general corporate purposes including the financing of the acquisition of EPP described above. Loans under the New Credit Facility bear interest at either the forward-looking term rate based on the secured overnight financing rate for a specified interest period or a rate based on the prime rate, in each case plus an applicable margin determined by reference to the Company's long-term issuer credit ratings from S&P, Moody's, and Fitch.
