(the Company or TTM) is a leading global printed circuit board (PCB) manufacturer, focusing on quick-turn and volume production of technologically advanced PCBs and backplane assemblies as well as a global designer and manufacturer of high-frequency radio frequency (RF) and microwave components and assemblies. 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 one-stop design and manufacturing solution enables 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, computing, automotive components, medical, industrial and instrumentation related products, as well as networking/communications infrastructure products. The Company’s customers include both original equipment manufacturers (OEMs) and electronic manufacturing services (EMS) providers. The accompanying consolidated condensed financial statements have been prepared by the Company, without audit, 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. It is suggested that these consolidated condensed financial statements 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 to the coronavirus (COVID-19) global pandemic, the global economy and financial markets have been disrupted and there is a significant amount of uncertainty about the length and severity of the consequences caused by the pandemic. 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. Actual results could differ materially from those estimates. The Company uses a 13-week fiscal quarter accounting period with the fourth quarter ending on the Monday nearest December 31. On January 19, 2020, the Company entered into a definitive equity interests purchase agreement with AKMMeadville Electronics (Xiamen) Co., Ltd (the Purchaser) for the sale of the Company’s following subsidiaries, which was completed on April 17, 2020: Shanghai Kaiser Electronics Co., Ltd. (SKE), Shanghai Meadville Electronics Co., Ltd. (SME), Shanghai Meadville Science & Technology Co., Ltd. (SP) and Guangzhou Meadville Electronics Co., Ltd. (GME) (collectively, the Mobility business unit). Prior to the closing of the sale of the Company’s Mobility business unit, all assets and liabilities attributable to the Mobility business unit have been aggregated under the captions “Current assets held for sale”, “Non-current assets held for sale”, “Current liabilities held for sale” and “Non-current liabilities held for sale”. For all periods presented in the consolidated condensed statements of operations, all sales, costs, expenses, income taxes and gain on sale attributable to the Mobility business unit have been aggregated under the caption “Income from discontinued operations, net of income taxes”. Prior year results have been recast to conform with the current presentation. Refer to Note 2, Discontinued Operations Unless otherwise noted, amounts and disclosures throughout these notes to consolidated condensed financial statements relate to continuing operations. These consolidated condensed financial statements reflect all adjustments (consisting only of normal recurring adjustments) which, in the opinion of management, are necessary to present fairly the financial position, the results of operations and cash flows of the Company for the periods presented. The results of operations for the interim periods are not necessarily indicative of the results to be expected for the full year. Reclassifications Certain prior year amounts in the consolidated condensed financial statements have been reclassified due to the sale of the Company’s Mobility business unit.

Discontinued Operations And Disposal Groups [Abstract]
Discontinued Operations	(2) Discontinued Operations On January 19, 2020, the Company entered into a definitive equity interests purchase agreement for the sale of the Company’s Mobility business unit. The sale was completed on April 17, 2020 for a base purchase price of $550,000, subject to customary purchase price adjustments. The base purchase price does not include certain accounts receivable of the divested business, which are estimated to total approximately $95,000. On April 18, 2020, the Company also entered into a Transition Services Agreement (TSA) with the Purchaser pursuant to which the Purchaser is receiving certain services (the Services) to enable it to operate the Mobility business unit after the closing of the sale of the Mobility business unit. The Services include finance and accounting, human resources, legal and compliance, sales, information technology, and other corporate support services. Under the TSA, the Services are being provided at cost for a period of up to 24 months. The Company does not anticipate this will have a material impact on its consolidated condensed financial statements. Further, on June 29, 2020, the Company entered into a Sales Force Agreement with the Purchaser pursuant to which the Company’s sales representatives will assist the Purchaser in selling PCBs manufactured by the Purchaser to certain customers for a commission for a period up to April 17, 2021. The Company does not anticipate this will have a material impact on its consolidated condensed financial statements. As the sale of the Company’s Mobility business unit represents a strategic shift that will have a major effect on the Company’s operations and financial results, in accordance with the provisions of FASB authoritative guidance on the presentation of financial statements, Mobility business unit results are classified as discontinued operations in the consolidated condensed statements of operations for all periods presented.

Leases [Abstract]
Leases	(3) Leases The Company leases some of its manufacturing and assembly plants, sales offices and equipment under non-cancellable operating leases that expire at various dates through 2049. The majority of the Company’s lease arrangements are comprised of fixed payments and certain leases consist of variable payments based on equipment usage. These variable payments are not included in the measurement of the right-of-use (ROU) asset or lease liability due to uncertainty of the payment amount and are recorded as lease expense in the period incurred. Certain leases contain renewal provisions at the Company’s option. Most of the leases require the Company to pay for certain other costs such as property taxes and maintenance. Certain leases also contain rent escalation clauses (step rents) that require additional rental amounts in the later years of the term. Rent expense for leases with step rents is recognized on a straight-line basis over the minimum lease term. The lease agreements do not contain any material residual value guarantees or material restrictive covenants. The components of lease expense were as follows: Quarter Ended Two Quarters Ended June 29, 2020 July 1, 2019 June 29, 2020 July 1, 2019 (In thousands) Operating lease cost $ 2,227 $ 2,132 $ 4,708 $ 4,164 Variable lease cost 137 102 243 261 Short-term lease cost 169 144 398 185 Supplemental cash flow information related to leases was as follows: Two Quarters Ended June 29, 2020 July 1, 2019 (In thousands) Cash paid for amounts included in the measurement of lease liabilities: Operating cash flows from operating leases $ 4,342 $ 4,164 Right-of-use assets obtained in exchange for new lease obligations: Operating leases 3,205 12,896 Supplemental balance sheet information related to leases was as follows: As of June 29, 2020 December 30, 2019 (In thousands) Operating lease right-of-use assets $ 21,993 $ 22,173 Other current liabilities 7,641 7,111 Operating lease liabilities 15,015 15,413 Total operating lease liabilities $ 22,656 $ 22,524 As of June 29, 2020 December 30, 2019 Weighted average remaining lease term 4.1 years 4.4 years Weighted average discount rate 3.76 % 3.92 % Maturities of operating lease liabilities were as follows (1) (In thousands) Less than one year $ 8,339 1 - 2 years 6,111 2 - 3 years 3,413 3 - 4 years 2,540 4 - 5 years 1,725 Thereafter 2,415 Total lease payments 24,543 Less imputed interest (1,887 ) Total $ 22,656 (1) Excludes $851 of legally binding minimum lease payments for leases signed but not yet commenced.

Income Tax Disclosure [Abstract]
Income Taxes	(9) Income Taxes The Company’s effective tax rate is impacted by tax rates in China and Hong Kong, the U.S. federal income tax rate, apportioned state income tax rates, generation of credits and deductions available to the Company as well as changes in valuation allowances and certain non-deductible items. Additionally, 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 June 29, 2020, the Company’s effective tax rate was impacted by a net discrete benefit of $6,871 and $4,818, respectively. This is related mainly to release of uncertain tax positions due to the expiration of the statute of limitation in foreign jurisdictions netted against (i) an increase of valuation allowance and withholding tax expense related to the announced closure of two of the E-M Solutions plants, (ii) retroactive approval of the Company’s renewal application for High and New Tax Enterprise status for two of the Company’s manufacturing subsidiaries in China (including the impact on the respective Company’s deferred tax assets) and (iii) by the 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 United States. 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 and the estimated federal/state tax impact. For those other companies with earnings currently being reinvested outside of the U.S., no deferred tax liabilities on undistributed earnings are recorded.

Derivative Instruments And Hedging Activities Disclosure [Abstract]
Financial Instruments	(10) Financial Instruments Derivatives Interest Rate Swaps The Company’s business is exposed to interest rate risk resulting from fluctuations in interest rates on certain LIBOR-based variable rate debt. Increases in interest rates would 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 May 15, 2018, the Company entered into a four-year 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. As of June 29, 2020, the fair value of the interest rate swap was recorded as a liability in the amount of $19,582 and included as a component of other long-term liabilities. The change in the fair value of the interest rate swap is recorded as a component of accumulated other comprehensive loss, net of tax. No ineffectiveness was recognized for the quarter and two quarters ended June 29, 2020 and July 1, 2019. The interest rate swap increased interest expense by $2,342 and $367 for the quarters ended June 29, 2020 and July 1, 2019, respectively, and $3,517 and $706 for the two quarters ended June 29, 2020 and July 1, 2019, respectively. Foreign Exchange Contracts The Company enters into foreign currency forward contracts to mitigate the impact of changes in foreign currency exchange rates and to reduce the volatility of purchases and other obligations generated in currencies other than its functional currencies. The Company’s foreign subsidiaries may at times purchase forward exchange contracts to manage their foreign currency risks in relation to certain purchases of machinery denominated in foreign currencies other than the Company’s functional currencies. The notional amount of the foreign exchange contracts as of June 29, 2020 and December 30, 2019 was approximately $1,361 and $1,994, respectively. The Company has designated certain of these foreign exchange contracts as cash flow hedges.

Significant Customers and Concentration of Credit Risk	(12) Significant Customers and Concentration of Credit Risk In the normal course of business, the Company extends credit to its customers. Most customers to which the Company extends credit are located outside the United States. The Company performs ongoing 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. 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 ended June 29, 2020, one customer accounted for approximately 11% of the Company’s net sales. There were no other customers that accounted for 10% or more of net sales for the quarter ended June 29, 2020. There were no customers that accounted for 10% or more of net sales for the quarter ended July 1, 2019 and two quarters ended June 29, 2020 and July 1, 2019.

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 as of June 29, 2020 and December 30, 2019 were as follows: As of As of June 29, 2020 December 30, 2019 Carrying Amount Fair Value Carrying Amount Fair Value (In thousands) Derivative assets, current $ 1 $ 1 $ 1 $ 1 Derivative liabilities, current 4 4 3 3 Derivative liabilities, non-current 19,582 19,582 12,067 12,067 Term Loan due September 2024 798,047 765,585 797,200 808,901 Senior Notes due October 2025 370,077 373,448 369,684 390,143 Convertible Senior Notes due December 2020 244,685 306,994 239,053 391,686 ABL Revolving Loans 70,000 70,000 70,000 70,000 The fair value of the derivative instruments was determined using pricing models developed based on the LIBOR 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 June 29, 2020 and December 30, 2019, which are considered Level 2 inputs. The fair value of the Convertible Senior Notes was estimated based on quoted market prices of the securities on an active exchange, which are considered Level 2 inputs. As of June 29, 2020 and December 30, 2019, the Company’s other financial instruments also included cash and cash equivalents, accounts receivable, and accounts payable. Due to short-term maturities, the carrying amount of these instruments approximates fair value. The Company’s cash and cash equivalents as of June 29, 2020 consisted of $305,263 held in the U.S., with the remaining $389,405 held by foreign subsidiaries. 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 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 June 29, 2020 and December 30, 2019. However, these amounts are not material to the consolidated condensed financial statements of the Company.

Earnings Per Share	(15) Earnings Per Share The following is a reconciliation of the numerator and denominator used to calculate basic earnings per share and diluted earnings per share from continuing operations for the quarter and two quarters ended June 29, 2020 and July 1, 2019: Quarter Ended Two Quarters Ended June 29, 2020 July 1, 2019 June 29, 2020 July 1, 2019 (In thousands, except per share amounts) Basic earnings: Basic earnings $ 9,346 $ 12,493 $ 6,126 $ 18,731 Diluted earnings: Net income $ 9,346 $ 12,493 $ 6,126 $ 18,731 Interest expense from Convertible Senior Notes, net of tax — 2,780 — — Diluted earnings $ 9,346 $ 15,273 $ 6,126 $ 18,731 Basic weighted average shares 106,295 105,470 105,990 104,893 Dilutive effect of performance-based restricted stock units, restricted stock units and stock options 1,190 637 1,441 967 Dilutive effect of assumed conversion of Convertible Senior Notes outstanding — 25,938 — — Diluted shares 107,485 132,045 107,431 105,860 Earnings per share: Basic $ 0.09 $ 0.12 $ 0.06 $ 0.18 Diluted $ 0.09 $ 0.12 $ 0.06 $ 0.18 PRUs, RSUs, and stock options to purchase 1,162 and 1,089 shares of common stock for the quarters ended June 29, 2020 and July 1, 2019, respectively, and 750 and 1,089 shares of common stock for the two quarters ended June 29, 2020 and July 1, 2019, 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 June 29, 2020 and July 1, 2019, and for RSUs and stock options, the options’ exercise prices or the total expected proceeds under the treasury stock method was greater than the average market price of common shares during the applicable quarter and two quarters and, as a result, the impact would be anti-dilutive. Outstanding warrants for the quarter and two quarters ended June 29, 2020 and July 1, 2019, to purchase common stock were not included in the computation of dilutive earnings per share because the strike price of the warrants to purchase the Company’s common stock were greater than the average market price of common shares during the applicable quarter, and therefore, the effect would be anti-dilutive. For the quarter and two quarters ended June 29, 2020 and for the two quarters ended July 1, 2019, the effect of shares of common stock related to the Company’s Convertible Senior Notes, based on the if-converted method, were not included in the computation of dilutive earnings per share as the impact would be anti-dilutive.

The Company has two reportable segments: PCB and E-M Solutions. The PCB reportable segment is comprised of multiple operating segments. Factors considered to determine whether operating segments can be aggregated into reportable segments included similarity regarding economic characteristics, products, production processes, type or classes of customers, distribution methods, and regulatory environments. 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.

Restructuring And Related Activities [Abstract]
Restructuring Charges	(19) Restructuring Charges On April 29, 2020, the Company announced the restructuring of its E-M Solutions business unit. The E-MS business unit consists of three Chinese manufacturing facilities with two being in Shanghai (SH BPA and SH E-MS) and one in Shenzhen (SZ). The Company will discontinue operations at the SH E-MS and SZ facilities while integrating the SH BPA facility into its PCB operations. The restructuring is another step in advancing the Company’s stated strategy of increasing its focus on differentiated higher margin products that more fully leverage the Company’s early engagement capabilities and industry leading engineering-based technology solutions. The closure of the SH E-MS and SZ facilities will not be immediate as the Company has obligations to fulfill with customers. The Company anticipates phasing out production over the remainder of 2020. As of June 29, 2020, the Company has incurred approximately $13,414 of restructuring charges since the April 29, 2020 announcement. The Company estimates that it will incur total charges related to restructuring of its E-M Solutions business unit of approximately $18,500 and accelerated depreciation expense of approximately $8,000. In connection with the restructuring of its E-M Solutions business unit and other global realignment restructuring efforts, the Company recognized employee separation, contract termination and other costs during the quarter and two quarters ended June 29, 2020 and July 1, 2019.
