Commitments and Contingencies Disclosure [Abstract]
Commitments and contingencies	Commitments and contingencies Bank guarantees As of June 27, 2025 and June 28, 2024, there were outstanding bank guarantees on behalf of the Company's subsidiary in Thailand for electricity usage and other normal business expenses totaling $2.3 million and $2.0 million, respectively, or Thai Baht 75.7 million and Thai Baht 73.2 million, respectively. In addition, there were other immaterial bank guarantees on behalf of the Company's subsidiary in Israel to support the subsidiary's operations related to the Israeli Customs department. 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 June 27, 2025, the Company had purchase obligations and other commitments to third parties of $1,409.6 million. Capital expenditure 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 June 27, 2025, the Company had total capital expenditure commitments to third parties of $201.3 million. 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. 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. As of June 27, 2025, 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 June 27, 2025, the Borrowers were in compliance with all of their financial covenants under the 2023 Credit Facility Agreement. Litigation and claim On June 28, 2024, Ngan In Leng and First Laser Limited (collectively, the “Plaintiffs”) filed a complaint in the Fuzhou Intermediate People’s Court (the “Court”) in Fuzhou, China against Fujian Enterprises (Holdings) Co., Ltd. (“FEHC”), Jian An Investment Limited (“Jian”), and Casix, Inc. (“Casix”), the Company's wholly-owned subsidiary located in the PRC. The complaint alleges unjust enrichment related to a purported investment in Casix by the Plaintiffs in 1997, which predates the Company's acquisition of Casix from JDS Uniphase Corporation. The Plaintiffs have requested that the Court order FEHC to return the unjust enrichment to the Plaintiffs in the amount of RMB 400 million, with interest from March 1, 2000, and order Jian and Casix to bear joint and several liability for all payment obligations of FEHC. In September 2024, the Court dismissed the lawsuit in its entirety based on jurisdictional grounds. The Plaintiffs have since appealed the Court’s ruling to the High People's Court of Fujian Province (the "Appellate Court"). In their appeal, the Plaintiffs now claim that Casix is the primary obligor to return the alleged unjust enrichment to the Plaintiffs. On November 24, 2024, the Appellate Court agreed to hear the appeal. At this time, the Company is not able to quantify any potential liability in connection with this litigation because of the early stage of this litigation.
