Commitments and Contingencies Disclosure [Abstract]
Commitments and contingencies	Commitments and contingencies Bank guarantees As of March 27, 2026 and June 27, 2025, there were outstanding bank guarantees on behalf of the Company's subsidiary in Thailand for electricity usage and other normal business expenses of Thai baht 77.3 million and Thai baht 75.7 million, respectively, or approximately $2.3 million for both periods. As of March 27, 2026, the Company had an outstanding bank guarantee on behalf of its subsidiary in China to support the subsidiary's operations of Chinese Renminbi ("RMB") 4.8 million ($0.7 million) and the bank guarantee was backed by cash collateral of $0.7 million. In addition, there were other immaterial bank guarantees on behalf of the Company's subsidiary in Israel to support the subsidiary's operations. Purchase obligations Purchase obligations represent legally binding commitments to purchase inventory and other commitments made in the normal course of business to meet operational requirements. Although open purchase orders are considered enforceable and legally binding, their terms generally give the Company the option to cancel, reschedule and/or adjust its requirements based on its business needs prior to the delivery of goods or performance of services. Obligations to purchase inventory and other commitments are generally expected to be fulfilled within one year. As of March 27, 2026, the Company had purchase obligations and other commitments to third parties of $2.74 billion. Capital expenditures In February 2025, the Company entered into a construction contract with a local contractor for construction of a new manufacturing building at the Company's Chonburi campus. The contract price is approximately $132.5 million (Thai baht 4.45 billion). As of March 27, 2026, the Company had total capital expenditure commitments to third parties of $164.7 million. Credit facility agreement On March 9, 2023, Fabrinet Thailand and the Parent Company (collectively, the “Borrowers”) and the Bank of Ayudhya Public Company Limited (the "Bank") entered into a credit facility agreement (the “2023 Credit Facility Agreement”), which provided a facility of $55.0 million. During the three months ended December 27, 2024, the Borrowers and the Bank amended the 2023 Credit Facility Agreement to reduce the facility to $30.0 million, which may be used for, among other things, an overdraft facility. The credit facility will mature on August 20, 2039. As of March 27, 2026, there was no amount outstanding under the 2023 Credit Facility Agreement. Under the 2023 Credit Facility Agreement, the Borrowers are required to maintain a debt-to-equity ratio of less than or equal to 1.5 times for Fabrinet Thailand and 1.0 times for the Parent Company. As of March 27, 2026, the Borrowers were in compliance with all of their financial covenants under the 2023 Credit Facility Agreement. Other Matters Following the February 2026 ruling by the United States Supreme Court striking down certain tariffs imposed under the International Emergency Economic Powers Act, U.S. Customs and Border Protection has since announced steps toward an administrative process to address potential tariff refunds. However, the availability, timing, and amount of any potential refunds remain uncertain and are subject to ongoing legal, regulatory, and administrative developments. The Company continues to monitor the situation, including any potential refunds of such tariffs, and evaluate the impact on its results of operations. As of March 27, 2026, the Company evaluated the potential recovery of previously incurred tariffs under a loss‑recovery model and has not recorded a receivable because recovery is not considered probable. Indemnification of directors and officers Cayman Islands law does not limit the extent to which a company’s memorandum and articles of association may provide for indemnification of directors and officers, except to the extent any such provision may be held by the Cayman Islands courts to be contrary to public policy, such as to provide indemnification against civil fraud or the consequences of committing a crime. Fabrinet’s amended and restated memorandum and articles of association provide for indemnification of directors and officers for actions, costs, charges, losses, damages and expenses incurred in their capacities as such, except that such indemnification does not extend to any matter in respect of any fraud or dishonesty that may attach to any of them. In accordance with Fabrinet’s form of indemnification agreement for its directors and officers, Fabrinet has agreed to indemnify its directors and officers against certain liabilities and expenses incurred by such persons in connection with claims by reason of their being such a director or officer. Fabrinet maintains a director and officer liability insurance policy that may enable it to recover a portion of any future amounts paid under the indemnification agreements.
