Accounting Policies [Abstract]
Nature of Operations and Basis of Presentation	(1) Nature of Operations and Basis of Presentation TTM Technologies, Inc. is a leading global manufacturer of technology products, including mission systems, RF components, RF microwave/microelectronic assemblies, and technologically advanced interconnect products, including PCBs and substrates. The Company provides time-to-market and volume production of advanced technology products and offers a one-stop design, engineering, and manufacturing solution to customers. This solution allows the Company to align technology developments with the diverse needs of the Company’s customers and to enable them to reduce the time required to develop new products and bring them to market. The Company serves a diversified customer base in various markets throughout the world, including aerospace and defense; automotive; data center and networking; and medical, industrial, and instrumentation. The Company’s customers include OEMs, EMS providers, ODMs, distributors, and government agencies (both domestic and allied foreign governments). The accompanying unaudited consolidated condensed financial statements have been prepared by the Company pursuant to the rules and regulations of the SEC. Certain information and disclosures normally included in financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to such rules and regulations. These consolidated condensed financial statements should be read in conjunction with the consolidated financial statements and the notes thereto included in the Company’s most recent Annual Report on Form 10-K. The preparation of financial statements in accordance with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the Company’s consolidated condensed financial statements and accompanying notes. Due, in part, to the conflicts between Russia and Ukraine and conflicts in the Middle East, as well as other global regions, the imposition of, or changes to, tariffs by the United States as well as retaliatory tariffs or measures by other countries, and the rising prices of global crude oil, the global economy and financial markets have continued to be volatile. As such, the Company has considered information available to it as of the date of issuance of these consolidated condensed financial statements and is not aware of any specific events or circumstances that would require an update to its estimates or judgments, or a revision to the carrying value of its assets or liabilities. The actual results the Company experienced may differ materially and adversely from its estimates. Derivative Instruments All derivatives are recognized on the Company's consolidated condensed balance sheets at fair value based on quoted market prices or the Company's estimate of their fair value, and are recorded in current or non-current assets or liabilities based on their maturity. Changes in the fair values of derivatives are recorded in net earnings or other comprehensive income (loss), based on whether the instrument is designated and effective as a hedge transaction and, if so, the type of hedge transaction. Gains or losses on derivative instruments reported in accumulated other comprehensive loss are reclassified to earnings in the period the hedged item affects earnings. If the underlying hedged transaction ceases to exist, any associated amounts reported in accumulated other comprehensive loss are reclassified to earnings at that time. On June 18, 2026, in connection with the proposed STG acquisition (see Note 11, Commitments and Contingencies for further information), the Company entered into a deal-contingent, forward-starting, fixed-for-fixed USD/CHF cross-currency swap with a major financial institution. The swap was entered to economically mitigate the foreign currency risk of the CHF-denominated purchase price and convert a portion of the anticipated USD financing into fixed-rate CHF financing. The instrument is contingent upon the closing of the proposed STG acquisition. The swap has notional exchanges of $381,083 and CHF 306,200, provides for the Company to receive fixed USD interest at 6.0% and pay fixed CHF interest at 3.025%, has an effective date of September 30, 2026, and matures on September 30, 2033. The instrument does not qualify for hedge accounting at inception. As of June 29, 2026, the fair value of the derivative instrument was a net liability of $13,994, of which $6,825 is included as a component of prepaid expenses and other current assets and $20,819 is included as a component of other long-term liabilities. During the quarter and two quarters ended June 29, 2026, the change in fair value of the derivative instrument of $13,994 was recorded as an unrealized loss on derivative instruments in the consolidated condensed statement of operations. Recently Issued Accounting Standards Not Yet Adopted In December 2025, the FASB issued ASU 2025-10, Accounting for Government Grants Received by Business Entities, to provide guidance on how business entities should recognize, measure, and present government grants received. The ASU is effective for annual periods beginning after December 15, 2028, and interim periods within those annual reporting periods. Early adoption is permitted. The guidance may be applied on a modified prospective basis, a modified retrospective basis, or a retrospective basis. The Company is currently evaluating the timing of the adoption and the impact of this ASU on its consolidated financial statements and related disclosures. In September 2025, the FASB issued ASU 2025-06, Targeted Improvements to the Accounting for Internal-Use Software, which amends the existing standard to remove all references to prescriptive and sequential software development project stages. Under this guidance, eligible software development costs will begin capitalization when management has authorized and committed to funding the software project, and it is probable that the project will be completed and the software will be used to perform the function intended. The ASU is effective for annual periods beginning after December 15, 2027, and interim periods within those annual reporting periods. Early adoption is permitted as of the beginning of an annual reporting period. The guidance may be applied on a prospective basis, a modified basis for in-process projects, or a retrospective basis. The Company is currently evaluating the timing of the adoption and the impact of this ASU on its consolidated financial statements and related disclosures. In November 2024, the FASB issued ASU 2024-03, Income Statement-Reporting Comprehensive Income-Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses, which requires disclosure in the notes to the financial statements of specified information about certain costs and expenses. In January 2025, the FASB issued ASU 2025-01, Income Statement-Reporting Comprehensive Income-Expense Disaggregation Disclosures (Subtopic 220-40): Clarifying the Effective Date, which amends the effective date of ASU 2024-03 to clarify that all public business entities are required to adopt the guidance in annual reporting periods beginning after December 15, 2026, and interim periods within annual reporting periods beginning after December 15, 2027. Early adoption of ASU 2024-03 is permitted. ASU 2024-03 should be applied either prospectively to financial statements issued for reporting periods after the effective date or retrospectively to any or all prior periods presented in the financial statements. The Company is currently evaluating the new guidance to determine the impact it may have on its consolidated financial statements and related disclosures, but expects additional disclosures upon adoption.
