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 26, 2026, the Company had purchase obligations and other commitments to third parties of $3.15 billion.

Credit facility agreement 2019 Credit Facility Agreement On August 20, 2019, Fabrinet Thailand (the “Borrower”) and Bank of Ayudhya Public Company Limited (the “Bank”) entered into a credit facility agreement (the “2019 Credit Facility Agreement”), which provides for a facility of Thai baht 110.0 million (approximately $3.6 million based on the applicable exchange rate as of September 27, 2019) and $160.9 million that may be used for, among other things, an overdraft facility, short-term loans against promissory notes, a letter of guarantee facility, a term loan facility and foreign exchange facilities. The Bank may approve any request for extension of credit under the 2019 Credit Facility Agreement and may increase or decrease any facility amount in its sole discretion. On August 17, 2026, the Borrowers and the Bank amended the 2019 Credit Facility Agreement to increase the facility to Thai baht 2.61 billion (approximately $78.3 million based on the applicable exchange rate as of August 17, 2026) and $100.0 million. The credit facility will mature on August 20, 2044. Under the 2019 Credit Facility Agreement, on August 17, 2026, the Borrower and the Bank entered into a term loan agreement (the “Term Loan Agreement”) in the original principal amount of Thai baht 2.50 billion (approximately $75.0 million based on the applicable exchange rate as of August 17, 2026). The proceeds from the term loan, together with cash on hand, were used to support the Company's capital expenditures. 2023 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 export bill discount. The credit facility will mature on March 9, 2043. As of June 26, 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 June 26, 2026, 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 alleged 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 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 complaint in its entirety based on jurisdictional grounds. The Plaintiffs subsequently appealed the Court’s ruling to the High People's Court of Fujian Province (the "Appellate Court"). In their appeal, the Plaintiffs claimed that Casix is the primary obligor to return the alleged unjust enrichment to the Plaintiffs. In November 2025, the Appellate Court upheld the Court's ruling and dismissed the lawsuit on jurisdictional grounds. In April 2026, the Plaintiffs appealed the Appellate Court’s ruling to the Supreme People’s Court of the People’s Republic of China (the “PRC Supreme Court”). The PRC Supreme Court held an initial hearing on July 2, 2026 and, on July 30, 2026, rendered a ruling accepting the case for retrial. The acceptance of the case for retrial does not represent a determination on the merits of the Plaintiffs' claims. 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. 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 June 26, 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.
