Accounting Policies [Abstract]
Nature of Operations and Basis of Presentation	(1) Nature of Operations and Basis of Presentation TTM Technologies, Inc. (the Company or TTM) is a leading global manufacturer of technology solutions including mission systems, radio frequency (RF) components/RF microwave/microelectronic assemblies, and quick-turn and technologically advanced printed circuit boards (PCB). 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, data center computing, automotive, medical, industrial and instrumentation related products, and networking. The Company’s customers include original equipment manufacturers (OEMs), electronic manufacturing services (EMS) providers, original design manufacturers (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 Securities and Exchange Commission (SEC). Certain information and disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America (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 conflict between Russia and Ukraine, and the conflict in Israel and the Gaza Strip, the global economy and financial markets have been volatile. As such, the Company has considered information available to it as of the date of issuance of these 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. The Company uses a 52/53 week fiscal calendar with the fourth quarter ending on the Monday nearest December 31. Recently Issued Accounting Standards Not Yet Adopted In March 2024, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2024-02, Codification Improvements - Amendments to Remove References to the Concepts Statements , to remove various references to concepts statements from the Accounting Standards Codification (ASC). These amendments clarify guidance, simplify wording or structure of guidance, and other minor improvements. The amendments are effective for fiscal years beginning after December 15, 2024, applied prospectively, with early adoption and retrospective application permitted. The impact of the adoption of the amendments in this update is not expected to be material to the Company's consolidated financial statements and related disclosures. In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures , which requires disclosure of disaggregated income taxes paid, prescribes standard categories for the components of the effective tax rate reconciliation, and modifies other income tax-related disclosures. The update will be effective for annual periods beginning after December 15, 2024. Early adoption is permitted for annual financial statements not yet issued or made available for issuance. 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. In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures , which updates reportable segment disclosure requirements primarily through enhanced disclosures about significant segment expenses. The amendments are effective for fiscal years beginning after December 15, 2023, and for interim periods within fiscal years beginning after December 15, 2024. Early adoption is permitted. The amendments should be applied retrospectively to 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. In October 2023, the FASB issued ASU 2023-06, Disclosure Improvements: Codification Amendments in Response to the Securities and Exchange Commission’s Disclosure Update and Simplification Initiative , which modifies the disclosure or presentation requirements of a variety of topics in the ASC in response to the SEC’s Release No. 33-10532, Disclosure Update and Simplification Initiative , and align the ASC requirements with the SEC’s regulations. For entities subject to the SEC's existing disclosure requirements, the effective date for each amendment will be the date on which the SEC's removal of that related disclosure from Regulation S-X or Regulation S-K becomes effective. However, if by June 30, 2027, the SEC has not removed the related disclosure from its regulations, the amendments will be removed from the Codification and not become effective. Early adoption is prohibited. The Company is currently evaluating the new guidance to determine the impact it may have on its consolidated financial statements and related disclosures.

Share Repurchase Program [Abstract]
Share Repurchase Program	(2) Share Repurchase Program On May 3, 2023, the Company's Board of Directors authorized and approved a share repurchase program (2023 Repurchase Program) , under which the Company may repurchase up to $ 100,000 in value of the Company’s outstanding shares of common stock from time to time through May 3, 2025 . The Company may repurchase shares through open market purchases, privately-negotiated transactions, or otherwise in accordance with applicable federal securities laws, including Rule 10b-18 of the Securities Exchange Act of 1934, as amended (Exchange Act), which sets certain restrictions on the method, timing, price, and volume of open market stock repurchases. In addition, the Company adopted one trading plan in accordance with Rule 10b5-1 of the Exchange Act to facilitate certain purchases that may be effected under the share repurchase program. The timing, manner, price, and amount of any repurchases will be determined at the Company’s discretion, and the share repurchase program may be suspended, terminated, or modified at any time for any reason. The repurchase program does not obligate the Company to acquire any specific number of shares. During the quarter ended July 1, 2024, the Company repurchased 1,390 shares of common stock for a total cost of $ 25,145 (including commissions) and during the two quarters ended July 1, 2024, the Company repurchased 1,990 shares of common stock for a total cost of $ 34,479 (including commissions). As of July 1, 2024, the remaining amount in value available to be repurchased under the 2023 Repurchase Program was approximately $ 41,088 .

Risks and Uncertainties [Abstract]
Significant Customers and Concentration of Credit Risk	(3) Significant Customers and Concentration of Credit Risk Financial instruments that are potentially subject to concentrations of credit risk are primarily cash and cash equivalents and accounts receivable. The Company had cash and cash equivalents held by its foreign subsidiaries of $ 174,623 and $ 195,928 as of July 1, 2024 and January 1, 2024, respectively. The Company maintains its cash and cash equivalents with major financial institutions and such balances exceed Federal Deposit Insurance Corporation insurance limits. The Company has not experienced any losses in such accounts and believes it is not exposed to any significant risk on cash and cash equivalents. In the normal course of business, the Company extends credit to its customers. Some customers to whom the Company extends credit are located outside the United States. The Company performs on-going credit evaluations of customers, does not require collateral, and considers the credit risk profile of the entity from which the receivable is due in further evaluating collection risk. As of July 1, 2024 and January 1, 2024, there were no customers that accounted for 10 % or more of the Company's accounts receivable. The Company’s customers include both OEMs and EMS companies. The Company’s OEM customers often direct a significant portion of their purchases through EMS companies. While the Company’s customers include both OEM and EMS providers, the Company measures customer concentration based on OEM companies, as they are the ultimate end customers. For the quarter and two quarters ended July 1, 2024, one customer accounted for approximately 11 % of the Company's net sales. For the quarter and two quarters ended July 3, 2023, one customer accounted for approximately 13 % of the Company's net sales.

The Company expects to recognize revenue on approximately 49 % of the remaining performance obligations for the Company’s long-term contracts over the next 12 months with the remaining amount expected to be recognized thereafter. For contracts in which anticipated total costs exceed the total expected revenue, an estimated loss is recognized in the period when identifiable. A provision for the entire amount of the estimated loss is recorded on a cumulative basis. The estimated remaining costs to complete for loss contracts as of July 1, 2024 and January 1, 2024 were $ 35,227 and $ 25,213 , respectively. Revenue recognized for the two quarters ended July 1, 2024 from amounts recorded as contract liabilities as of January 1, 2024 was $ 28,205 . Revenue recognized for the two quarters ended July 3, 2023 from amounts recorded as contract liabilities as of January 2, 2023 was $ 27,069 . Revenue from products and services transferred to customers over time and at a point in time accounted for 96 % and 4 % , respectively, of the Company’s revenue for both the quarter and two quarters ended July 1, 2024 and July 3, 2023.

Income Tax Disclosure [Abstract]
Income Taxes	(9) Income Taxes The Company’s effective tax rate is impacted by the mix of foreign and U.S. income, tax rates in China and Hong Kong, the U.S. federal income tax rate, apportioned state income tax rates, the generation of credits, and deductions available to the Company as well as changes in valuation allowances and certain non-deductible items. No tax benefit was recorded on the losses incurred in certain foreign jurisdictions as a result of corresponding increases in the valuation allowances in these jurisdictions. During the quarter and two quarters ended July 1, 2024, the Company’s effective tax rate was impacted by a net discrete benefit of $ 3,348 and $ 2,861 , respectively. This is primarily related to a windfall tax benefit of the stock-based compensation releases and finalization of China and Canada corporate income tax returns, which was partially offset by the approval of the Company’s renewal application for High and New Technology Enterprise status for two of the Company’s manufacturing subsidiaries in China (including the impact on the respective subsidiaries’ deferred tax amounts), and accrued interest expense on existing uncertain tax positions. The Company has various foreign subsidiaries formed or acquired to conduct or support its business outside the U.S. The Company expects its earnings attributable to most foreign subsidiaries may be repatriated back to the U.S. and so a deferred tax liability has been recorded for foreign withholding taxes and the estimated federal/state tax impact on any repatriation. For those other companies with earnings currently being reinvested outside of the U.S., no deferred tax liability on undistributed earnings has been recorded.

Segment Reporting [Abstract]
Segment Information	(10) Segment Information The Company’s reportable segments are the segments for which separate financial information is available and upon which operating results are evaluated by the chief operating decision maker to assess performance and to allocate resources. The Company, including the chief operating decision maker, evaluates segment performance based on reportable segment income, which is operating income before amortization of intangibles. Interest expense and interest income are not presented by segment since they are not included in the measure of segment profitability reviewed by the chief operating decision maker. All inter‑segment transactions have been eliminated. Net sales by segment, operating segment income, and segment assets were as follows: Quarter Ended Two Quarters Ended July 1, 2024 July 3, 2023 July 1, 2024 July 3, 2023 (In thousands) Net Sales: PCB $ 596,107 $ 536,531 $ 1,157,948 $ 1,070,642 RF&S Components 9,030 9,978 17,302 20,304 Total net sales $ 605,137 $ 546,509 $ 1,175,250 $ 1,090,946 Operating Segment Income: PCB $ 90,927 $ 58,479 $ 160,579 $ 110,113 RF&S Components 2,052 3,202 3,714 5,370 Corporate and Other ( 41,402 ) ( 33,998 ) ( 81,884 ) ( 63,496 ) Total operating segment income 51,577 27,683 82,409 51,987 Amortization of definite-lived intangibles (1) ( 12,591 ) ( 6,275 ) ( 26,356 ) ( 34,047 ) Total operating income 38,986 21,408 56,053 17,940 Total other expense ( 8,454 ) ( 7,998 ) ( 11,452 ) ( 18,268 ) Income (loss) before income taxes $ 30,532 $ 13,410 $ 44,601 $ ( 328 ) As of July 1, 2024 January 1, 2024 (In thousands) Segment Assets: PCB $ 2,103,247 $ 2,032,202 RF&S Components 136,021 142,520 Corporate and Other 1,104,096 1,148,941 Total assets $ 3,343,364 $ 3,323,663 (1) Amortization of definite-lived intangibles relates to the PCB and RF&S Components reportable segments.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Financial Instruments	(12) Financial Instruments Derivatives Interest Rate Swaps The Company’s business is exposed to risk resulting from fluctuations in interest rates on certain SOFR based variable rate debt. Increases in interest rates increase interest expenses relating to the outstanding variable rate borrowings and increase the cost of debt. Fluctuations in interest rates can also lead to significant fluctuations in the fair value of the debt obligations. On March 23, 2023, the Company entered into a four-year pay-fixed, receive-floating (1-month CME Term SOFR), interest rate swap arrangement with a notional amount of $ 250,000 for the period beginning April 1, 2023 and ending on April 1, 2027 . Under the terms of the interest rate swap, the Company pays a fixed rate of 3.49 % against a portion of its Term SOFR-based debt and receives a floating 1-month CME Term SOFR during the swap period. At inception, the Company designated the interest rate swap as a cash flow hedge and the fair value of the interest rate swap was zero . The change in the fair value of the interest rate swap is recorded as a component of accumulated other comprehensive loss, net of tax in the Company's consolidated condensed balance sheets. No ineffectiveness was recognized for the quarter and two quarters ended July 1, 2024. Commodity Price Risk Management The Company uses various raw materials in the manufacturing of PCBs. Copper clad laminates (CCLs), a key raw material for the manufacture of PCBs, are made from epoxy resin, glass cloth, and copper foil. The Company only buys a small amount of copper directly. However, copper is a major driver of laminate cost. The Company enters into commodity contracts to hedge copper as a proxy for hedging laminate. As of July 1, 2024, the Company has commodity contracts with a notional quantity of (i) 0.6 metric tonnes for the period beginning July 1, 2024 and ending on September 30, 2024 , (ii) 0.5 metric tonnes for the period beginning October 1, 2024 and ending on December 31, 2024 , (iii) 0.5 metric tonnes for the period beginning January 1, 2025 and ending on March 31, 2025 , and (iv) 0.5 metric tonnes for the period beginning April 1, 2025 and ending on June 30, 2025 . The changes in the fair value of these commodity contracts are recorded in cost of goods sold in the consolidated condensed statements of operations. The commodity contracts decreased cost of goods sold by $ 609 and $ 1,040 for the quarter and two quarters ended July 1, 2024, respectively. The commodity contracts increased cost of goods sold by $ 1,423 and $ 382 for the quarter and two quarters ended July 3, 2023, respectively. These commodity contracts are not designated as accounting hedges. The fair values of derivative instruments in the consolidated condensed balance sheets were as follows: Asset/(Liability) Fair Value July 1, 2024 January 1, 2024 (In thousands) Cash flow derivative instruments designated as hedges: Interest rate swap: Prepaid expenses and other current assets $ 3,876 $ 3,253 Deposits and other non-current assets 1,917 — Other long-term liabilities — ( 1,476 ) Net asset $ 5,793 $ 1,777 Cash flow derivative instruments not designated as hedges: Commodity contracts: Prepaid expenses and other current assets $ 889 $ — Other current liabilities — ( 297 ) Net asset (liability) $ 889 $ ( 297 ) Amounts recorded in accumulated other comprehensive loss related to derivatives designated as cash flow hedges, as well as the amounts recorded in each caption in the consolidated condensed statements of operations when derivative amounts are reclassified out of accumulated other comprehensive loss were as follows: Quarter Ended July 1, 2024 Quarter Ended July 3, 2023 Financial Gain Recognized in Other Comprehensive Income Amounts Gain Recognized in Other Comprehensive Income Amounts (In thousands) Cash flow derivative instruments designated as hedges: Interest rate swap Interest expense $ 1,232 $ 1,158 $ 7,710 $ ( 968 ) Two Quarters Ended July 1, 2024 Two Quarters Ended July 3, 2023 Financial Gain Recognized in Other Comprehensive Income Amounts Gain Recognized in Other Comprehensive Loss Amounts (In thousands) Cash flow derivative instruments designated as hedges: Interest rate swap Interest expense $ 6,340 $ ( 2,323 ) $ 6,809 $ ( 968 ) The activity associated with the designated cash flow hedges reflected in accumulated other comprehensive loss was as follows: Two Quarters Ended July 1, 2024 July 3, 2023 (In thousands) Beginning balance, net of tax $ 1,263 $ ( 85 ) Changes in fair value gain, net of tax 4,740 5,140 Reclassification to earnings ( 1,728 ) ( 721 ) Ending balance, net of tax $ 4,275 $ 4,334

Fair Value Measures

Fair Value Disclosures [Abstract]
Fair Value Measures	(13) Fair Value Measures The Company measures at fair value its financial and non-financial assets by using a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date, essentially an exit price, based on the highest and best use of the asset or liability. The carrying amount and estimated fair value of the Company’s financial instruments were as follows: As of July 1, 2024 As of January 1, 2024 Carrying Fair Value Carrying Fair Value (In thousands) Derivative assets, current $ 4,765 $ 4,765 $ 3,282 $ 3,282 Derivative assets, non-current 1,917 1,917 — — Derivative liabilities, current 65 65 297 297 Derivative liabilities, non-current — — 1,476 1,476 Senior Notes due March 2029 496,273 457,305 495,915 455,035 Term Loan due May 2030 339,780 347,585 341,921 351,743 ABL Revolving Loans 80,000 80,000 80,000 80,000 The fair value of the derivative instruments was determined using pricing models developed based on the 1-month CME Term SOFR swap rate, foreign currency exchange rates, and other observable market data, including quoted market prices, as appropriate using Level 2 inputs. The values were adjusted to reflect non-performance risk of both the counterparty and the Company, as necessary. The fair value of the long-term debt was estimated based on quoted market prices or discounting the debt over its life using current market rates for similar debt as of July 1, 2024 and January 1, 2024, which are considered Level 2 inputs. As of July 1, 2024 and January 1, 2024, the Company’s other financial instruments included cash and cash equivalents, accounts receivable, contract assets, accounts payable, and contract liabilities. The carrying amount of these instruments approximates fair value. The majority of the Company’s non-financial assets and liabilities, which include goodwill, intangible assets, inventories, and property, plant, and equipment, are not required to be carried at fair value on a recurring basis. However, if certain triggering events occur (or are tested at least annually in the case of goodwill) such that a non-financial instrument is required to be evaluated for impairment, based upon a comparison of the non-financial instrument’s fair value to its carrying value, an impairment is recorded to reduce the carrying value to the fair value, if the carrying value exceeds the fair value.

Commitments and Contingencies

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	(14) Commitments and Contingencies Legal Matters The Company is subject to various legal matters, which it considers normal for its business activities. While the Company currently believes that the amount of any reasonably possible loss for known matters would not be material to the Company’s financial condition, the outcome of these actions is inherently difficult to predict. In the event of an adverse outcome, the ultimate potential loss could have a material adverse effect on the Company’s financial condition or results of operations in a particular period. The Company has accrued amounts for its loss contingencies which are probable and estimable as of July 1, 2024 and January 1, 2024 and included as a component of other current liabilities. However, these amounts are not material to the consolidated condensed financial statements of the Company. Offset Agreements The Company has and may continue to enter into industrial cooperation agreements, sometimes referred to as offset agreements, as a condition to obtaining orders for products and services from customers in foreign countries. These agreements are intended to promote investment in the applicable country, and the Company’s obligations under these agreements may be satisfied through activities that do not require the Company to use cash, including transferring technology or providing manufacturing and other consulting support. The obligations under these agreements may also be satisfied through the use of cash for activities such as purchasing supplies from in-country vendors, setting up support centers, research and development investments, acquisitions, and building or leasing facilities for in-country operations. The amount of the offset requirement is determined by contract value awarded and negotiated percentages with customers. As of July 1, 2024, the Company had outstanding offset agreements of approximately $ 27,963 , some of which extend through 2028. Offset programs usually extend over several years and in some cases provide for penalties in the event the Company fails to perform in accordance with contract requirements. To date, the Company has not been obligated to pay any such penalties. Supplier Finance Program Obligations The Company has agreements with financial institutions to facilitate payments to certain suppliers.

Earnings Per Share [Abstract]
Earnings Per Share	(15) Earnings Per Share The reconciliation of the numerator and denominator used to calculate basic earnings per share and diluted earnings per share is as follows: Quarter Ended Two Quarters Ended July 1, 2024 July 3, 2023 July 1, 2024 July 3, 2023 (In thousands, except per share amounts) Net income $ 26,352 $ 6,824 $ 36,818 $ 1,010 Basic weighted average shares 101,234 102,759 101,593 102,570 Dilutive effect of performance-based restricted stock 2,655 2,061 2,400 2,005 Diluted shares 103,889 104,820 103,993 104,575 Earnings per share: Basic $ 0.26 $ 0.07 $ 0.36 $ 0.01 Diluted $ 0.25 $ 0.07 $ 0.35 $ 0.01 PRUs, RSUs, and stock options to purchase 330 and 177 shares of common stock for the quarter and two quarters ended July 1, 2024, respectively, and 524 and 345 shares of common stock for the quarter and two quarters ended July 3, 2023, respectively, were not included in the computation of diluted earnings per share. The PRUs were not included in the computation of diluted earnings per share because the performance conditions had not been met at July 1, 2024 and July 3, 2023, and for the RSUs and stock options, the options’ exe rcise prices or the total expected proceeds under the treasury stock method was greater than the average market price of common stock during the applicable quarter and two quarters and, as a result, the impact would be anti-dilutive.

Stock-Based Compensation

Share-Based Payment Arrangement [Abstract]
Stock-Based Compensation	(16) Stock-Based Compensation Performance-based Restricted Stock Units The Company maintains a long-term incentive program for executives that provides for the issuance of PRUs, representing hypothetical shares of the Company’s common stock that may be issued. Under the PRU program, a target number of PRUs is awarded at the beginning of each three-year performance period. The number of shares of common stock released at the end of the performance period depends on performance during the period and may range from zero to 2.4 times the target number for PRUs awarded before 2023 and zero to 2.0 times the target number for PRUs awarded in 2023 and thereafter. For PRUs awarded before 2023, the performance metrics of the PRU program are based on (a) annual financial targets, which are based on revenue and earnings before interest, tax, depreciation, and amortization expense (EBITDA), each equally weighted, and (b) an overall modifier based on the Company’s total stockholder return (TSR) relative to a group of peer companies selected by the Company’s compensation committee, over the three‑year performance period. For PRUs awarded in 2023 and thereafter, the performance metrics of the PRU program are based on (a) annual financial targets, which are based on revenue and EBITDA, each equally weighted, and (b) the three-year TSR performance result, which will be an additive component to the Company’s financial results of the aggregated three-year measurement period. Under the PRU program, financial goals with respect to one or more target milestones are set at the beginning of each fiscal year and performance is reviewed at the end of that year. The percentage to be applied to each participant’s target award ranges from zero to 160 % for PRUs awarded before 2023 and zero to 200 % for PRUs awarded in 2023 and thereafter, based upon the extent to which the target milestones are achieved. If specific performance threshold levels for the target milestones are met, the amount earned for that element over the three-year performance period will be applied equally for PRUs awarded before 2023 and 80 % for PRUs awarded in 2023 and thereafter, of the participants’ PRU award to determine the number of units earned. At the end of the three-year performance period, the total units earned, if any, are adjusted by the TSR calculation. The TSR calculation is a percentage ranging from zero to 150 % for PRUs awarded before 2023 and zero to 200 % for PRUs awarded in 2023 and thereafter, determined on the Company’s TSR based on stock price changes relative to a group of peer companies selected by the Company’s compensation committee for the same three-year period. For outstanding PRU awards granted before 2023, the TSR is used as an overall modifier of the three-year performance period such that the base calculations are multiplied by the TSR modifier, ranging from zero to 200 %, based on the relative performance of the Company’s stock price as compared to its TSR peer group. For PRUs awarded in 2023 and thereafter, the TSR calculation will be applied to 20 % of the participants’ PRU award to determine the number of additional units earned. Stock-based Compensation Expense and Unrecognized Compensation Costs Stock-based compensation expens e recognized in the accompanying consolidated condensed statements of operations was as follows: Quarter Ended Two Quarters Ended July 1, 2024 July 3, 2023 July 1, 2024 July 3, 2023 (In thousands) Cost of goods sold $ 1,941 $ 1,497 $ 3,970 $ 3,159 Selling and marketing 836 698 1,704 1,439 General and administrative 3,468 2,677 7,063 5,239 Research and development 335 249 630 524 Stock-based compensation expense recognized $ 6,580 $ 5,121 $ 13,367 $ 10,361 A summary of total unrecognized compensation costs as of July 1, 2024 was as follows: Unrecognized Compensation Costs Remaining Weighted Average (In thousands) (In years) RSU awards $ 56,973 1.7 PRU awards 7,314 1.8 Total $ 64,287
