Nature of Operations and Summary of Significant Accounting Policies | (1) Nature of Operations and Summary of Significant Accounting Policies Nature of Operations 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, 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 Company operates on a 52 or 53 week fiscal calendar with the fourth quarter ending on the Monday nearest December 31. Fiscal years 2024, 2023, and 2022 consisted of 52 weeks ended on December 30, 2024, January 1, 2024, and January 2, 2023, respectively. All references to years relate to fiscal years unless otherwise noted. Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America (U.S. GAAP) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amount of revenues and expenses during the reporting period. These estimates and assumptions are based on management’s best estimates and judgment. Due, in part, to the conflict between Russia and Ukraine as well as other global regions, the global economy and financial markets have been volatile in recent years. 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. Management evaluates its estimates and assumptions on an ongoing basis using historical experience and other factors, including the economic environment, which management believes to be reasonable under the circumstances. Management adjusts such estimates and assumptions when facts and circumstances dictate. The actual results the Company experienced may differ materially and adversely from its estimates. To the extent there are material differences between the estimates and actual results, the Company’s future result of operations will be affected. Principles of Consolidation The consolidated financial statements include the accounts of TTM and its subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation. Foreign Currency Translation and Transactions The functional currency of one of the Company’s subsidiaries is the Chinese Renminbi (RMB). Accordingly, assets and liabilities are translated into U.S. dollars using period-end exchange rates. Sales and expenses are translated at the average exchange rates in effect during the period. The resulting translation gains or losses are recorded as a component of accumulated other comprehensive loss in the consolidated statement of stockholders’ equity and the consolidated statement of comprehensive income. Net gains and losses resulting from foreign currency re-measurements and transactions are included in income as a component of other, net in the consolidated statements of operations and totaled $ 1,218 gain, $ 4,059 loss, and $ 12,756 gain for the years ended December 30, 2024, January 1, 2024, and January 2, 2023 , respectively. Cash Equivalents The Company considers highly liquid investments with insignificant interest rate risk and original maturities to the Company of three months or less to be cash equivalents. Accounts Receivable and Allowance for Doubtful Accounts Accounts receivable are reflected at estimated net realizable value, do not bear interest and do not generally require collateral. The Company performs credit evaluations of its customers and adjusts credit limits based upon payment history and the customer’s current creditworthiness. The Company maintains an allowance for doubtful accounts based upon a variety of factors. The Company considers both current and forecasted future economic conditions in determining the adequacy of its allowance for doubtful accounts. The Company’s allowance for doubtful accounts was $ 3,248 and $ 3,041 as of December 30, 2024 and January 1, 2024 , respectively. Inventories Inventories are stated at the lower of cost (based on standard cost, which approximates first-in, first-out method) or net realizable value. Assessments to value the inventory at the lower of the actual cost to purchase and/or manufacture the inventory, or net realizable value of the inventory, are based upon assumptions about future demand and market conditions. As a result of the Company’s assessments, when the net realizable value of inventory is less than the carrying value, the inventory cost is written down to the net realizable value and the write down is recorded as a charge to cost of goods sold. Property, Plant, and Equipment, Net Property, plant, and equipment are recorded at cost. Depreciation expense is computed using the straight-line method over the estimated useful lives of the assets. Assets recorded under leasehold improvements are amortized using the straight-line method over the lesser of their useful lives or the related lease term. The Company uses the following estimated useful lives: Land use rights 50 - 99 years Buildings and improvements 7 - 50 years Machinery and equipment 3 - 10 years Furniture and fixtures 3 - 7 years Upon retirement or other disposition of property, plant, and equipment, the cost and related accumulated depreciation are removed from the accounts. The resulting gain or loss is included in the determination of operating income in the period incurred. Depreciation expense on property, plant, and equipment was $ 105,233 , $ 99,155 , and $ 91,276 for the years ended December 30, 2024, January 1, 2024, and January 2, 2023, respectively. The Company capitalizes interest on borrowings during the active construction period of major capital projects. Capitalized interest is amortized over the average useful lives of such assets, which primarily consist of buildings and machinery and equipment. The Company capitalized interest costs of $ 4,006 , $ 2,272 , and $ 731 during the years ended December 30, 2024, January 1, 2024, and January 2, 2023, respectively, in connection with various capital projects. Major renewals and betterments are capitalized and depreciated over their estimated useful lives while minor expenditures for maintenance and repairs are included in operating income as incurred. Goodwill Goodwill represents the excess of purchase price of an acquisition over the fair value of net assets acquired. Goodwill is not amortized but instead is assessed for impairment, at a reporting unit level, annually and when events and circumstances warrant an evaluation. Goodwill is allocated to reporting units, which are operating segments or one level below the Company’s operating segments (the component level). Reporting units are determined by the discrete financial information available for the component and whether it is regularly reviewed by segment management. Components are aggregated into a single reporting unit if they share similar economic characteristics. The Company evaluates its goodwill on an annual basis in the fourth quarter or more frequently if it believes indicators of impairment exist. The Company assesses qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount or performs a quantitative impairment test. When tested quantitatively, the Company compares the fair value of the applicable reporting unit with its carrying value. In making this assessment, management relies on a number of factors, including expected future operating results, business plans, economic projections, anticipated future cash flows, business trends and declines in the Company’s market capitalization. The Company estimates the fair values of its reporting units using a combination of the discounted cash flow (DCF) and market approaches. If the carrying amount of a reporting unit exceeds the reporting unit’s fair value, the amount by which the carrying value exceeds the fair value is recognized as an impairment loss. See Note 6, Goodwill , for further details. Intangible Assets Intangible assets include customer relationships and technology, which are being amortized over their estimated useful lives on a straight-line basis. The estimated useful lives of such intangibles range from 5 years to 13 years . Impairment of Long-lived Assets Long-lived tangible assets, including property, plant, and equipment, assets held for sale, and definite-lived intangible assets, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying value of the asset or asset groups may not be recoverable. The Company regularly evaluates whether events or circumstances have occurred that indicate possible impairment and relies on a number of factors, including expected future operating results, business plans, economic projections, and anticipated future cash flows. The Company uses an estimate of the future undiscounted net cash flows of the related asset or asset group over the remaining life in measuring whether the assets are recoverable. If the sum of the undiscounted cash flows is less than the carrying amount of the net assets, impairment is measured based on the difference between the net asset’s carrying value and estimated fair value. Fair value is determined through various valuation techniques, including cost-based, market, and income approaches as considered necessary. The Company classifies assets to be sold as assets held for sale when (1) Company management has approved and commits to a plan to sell the asset; (2) the asset is available for immediate sale in its present condition and is ready for sale; (3) an active program to locate a buyer and other actions required to sell the asset have been initiated; (4) the sale of the asset is probable; (5) the asset is being actively marketed for sale at a price that is reasonable in relation to its current fair value; and (6) it is unlikely that significant changes to the plan will be made or that the plan will be withdrawn. Assets classified as held for sale are recorded at the lower of the carrying amount or fair value less the cost to sell. The Company classifies assets held for use when a decision to dispose of an asset or a business is made and the held for sale criteria are not met. In evaluating the recoverability of property and intangible assets subject to amortization, in a held for use business, the carrying value is first compared to the sum of the undiscounted cash flows expected to result from the use and eventual disposition. If the carrying value exceeds the undiscounted expected cash flows, then a fair value analysis is performed. An impairment charge is recognized if the carrying value exceeds the fair value. Leases The Company determines if an arrangement is a lease at inception. Operating leases are included in operating lease right-of-use (ROU) assets, and lease liabilities are included in other current liabilities and operating lease liabilities on the consolidated balance sheets. Finance lease ROU assets are included in property, plant, and equipment, net and lease liabilities are included in other current liabilities and other long-term liabilities on the consolidated balance sheets. ROU assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent the Company’s obligation to make lease payments arising from the lease. Operating and finance lease ROU assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. As most of the Company’s leases do not provide an implicit rate, the Company uses its incremental borrowing rate based on the information available at the commencement date in determining the present value of lease payments. The operating and finance lease ROU assets also include any lease payments made and excludes lease incentives. Lease terms may include options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option. Operating lease expense is recognized on a straight-line basis over the lease term. Finance lease expense is recognized based on the effective interest method over the lease term. The Company has lease agreements with lease and non-lease components and accounts for the lease and non-lease components as a single lease component. Revenue Recognition The Company derives revenues primarily from the sale of PCBs, engineered systems using customer-supplied engineering and design plans as well as long-term contracts related to the design and manufacture of highly sophisticated intelligence, surveillance, and communications solutions, RF and microwave/microelectronics components, assemblies, and subsystems. In the absence of a sales agreement, the Company’s standard terms and conditions apply. Revenue is recognized when control of the promised goods or services is transferred to the Company’s customers, in an amount that reflects the consideration to which it expects to be entitled in exchange for those goods or services. The Company applies a five-step approach in determining the amount and timing of revenue to be recognized: (1) identifying the contract with a customer; (2) identifying the performance obligations in the contract; (3) determining the transaction price; (4) allocating the transaction price to the performance obligations in the contract; and (5) recognizing revenue when the corresponding performance obligation is satisfied. Revenue Streams For PCBs and engineered systems, including pursuant to the Company’s long-term contracts related to the manufacture of highly sophisticated intelligence, surveillance, and communications solutions, components, assemblies, and subsystems, orders for products generally correspond to the production schedules of the Company’s customers and are supported with firm purchase orders. The Company’s customers have continuous control of the work in progress and finished goods throughout the PCB and engineered systems manufacturing process, as these are built to customer specifications with no alternative use, and there is an enforceable right to payment for work performed to date. As a result, the Company recognizes revenue progressively over time based on the extent of progress towards completion of the performance obligation. Revenue recognized is based on a cost method as it best depicts the transfer of control to the customer which takes place as we incur costs. Revenues are recorded proportionally as costs are incurred. 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 December 30, 2024 and January 1, 2024 were $ 36,976 and $ 25,213 , respectively, and the provision is recorded as a reduction to gross margin on the consolidated statements of operations. In addition, the Company manufactures components, assemblies, subsystems, and completed systems which service its RF and Specialty Components (RF&S Components) and certain aerospace and defense customers. The Company recognizes revenue at a point in time upon transfer of control of the products to the customer. Point in time recognition was determined as the customer does not simultaneously receive or consume the benefits provided by the Company’s performance and the asset being manufactured has alternative uses to the Company. Performance Obligations Each distinct promise to transfer products is considered to be an identified performance obligation for which revenue is recognized upon transfer of control of the products to the customer. A contract’s transaction price is allocated to each distinct performance obligation and recognized as revenue when, or as, the performance obligation is satisfied. The majority of the Company's contracts have a single performance obligation as the promise to transfer the individual good or service is not separately identifiable from other promises in the contract and is, therefore, not distinct. As of December 30, 2024, the aggregate amount of the transaction price allocated to remaining performance obligations for the Company’s long-term contracts was $ 452,793 . The Company expects to recognize revenue on approximately 54 % of the remaining performance obligations for the Company’s long‑term contracts over the next twelve months with the remaining amount recognized thereafter. The remaining performance obligations for the Company’s short‑term contracts are expected to be recognized within one year . Transaction Price The Company provides customers a limited right of return for defective PCBs including components, assemblies, and subsystems. Estimates of returns are treated as variable consideration for purposes of determining the transaction price. The Company accrues an estimate for sales returns and allowances progressively over time based on the extent of progress towards completion of the performance obligation using the Company’s judgment based on historical results and anticipated returns. To the extent actual experience varies from its historical experience, revisions to the sales returns and allowances accrual may be required. Sales returns and allowances are recorded as a reduction of revenue and included as a component of other current liabilities on the consolidated balance sheets. Shipping and handling fees and related freight costs and supplies associated with shipping products to customers are included as a component of cost of goods sold. Warranty-related services are not considered a separate performance obligation. Incremental warranty costs that are not related to sales returns are recorded in other current liabilities on the consolidated balance sheets and cost of goods sold on the consolidated statements of operations. The following summarizes the activity in the Company’s sales returns and allowances: For the Year Ended December 30, 2024 January 1, 2024 January 2, 2023 (In thousands) Balance at beginning of year $ 12,301 $ 12,319 $ 12,853 Addition charged as a reduction of sales 2,787 4,692 2,410 Deductions ( 4,281 ) ( 4,719 ) ( 2,914 ) Effect of foreign currency exchange rates ( 30 ) 9 ( 30 ) Balance at end of year $ 10,777 $ 12,301 $ 12,319 Contract Balances Accounts receivable represents the Company’s unconditional right to receive consideration from its customer. Payments are generally due within 90 days or less of invoicing and do not include a significant financing component. To date, there have been no material credit losses on accounts receivable. A contract asset is recognized when the Company has recognized revenue, but not issued an invoice for payment. Amounts will be invoiced when applicable contract terms, such as the achievement of specified milestones or product delivery, are met. Contract assets represent unbilled amounts for work performed to date and are transferred to receivables when the entitlement to payment becomes unconditional. As of December 30, 2024, total contract assets were $ 386,817 , of which $ 381,382 are expected to be collected within one year and recorded as contract assets and $ 5,435 are expected to be collected after one year and included as a component of deposits and other non-current assets on the consolidated balance sheets. As of January 1, 2024, total contract assets were $ 303,307 , of which $ 292,050 were expected to be collected within one year and recorded as contract assets and $ 11,257 were expected to be collected after one year and included as a component of deposits and other non-current assets on the consolidated balance sheets. The increase in total contract assets in 2024 is primarily due to an increase in unbilled receivables. In 2024, there were no material impairment losses on contract assets. A contract liability is recognized when the Company has received payment in advance for the future transfer of goods or services. The Company’s contract liabilities are reduced as the contract requirements are fulfilled. Contract liabilities were $ 170,915 and $ 126,508 as of December 30, 2024 and January 1, 2024, respectively, and represent customer advances for work yet to be performed. The contract liabilities increased by $ 44,407 due to timing of customer billings and/or payments. Revenue recognized for the year ended December 30, 2024 from amounts recorded as contract liabilities as of January 1, 2024 was $ 37,457 . The Company has elected to account for shipping and handling activities as a fulfillment cost as permitted by the standard. All incremental customer contract acquisition costs are expensed as they are incurred as the amortization period of the asset that the Company otherwise would have recognized is one year or less in duration. Disaggregated Revenue 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 in both 2024 and 2023 . Revenue from products and services transferred to customers over time and at a point in time accounted for 97 % and 3 % , respectively, of the Company’s revenue in 2022. Disaggregated revenue by principal end markets within reportable segments was as follows for the periods shown: For the Year Ended December 30, 2024 PCB RF&S Components Total (In thousands) End Markets: Aerospace and Defense $ 1,127,529 $ — $ 1,127,529 Automotive 315,924 — 315,924 Data Center Computing 502,258 619 502,877 Medical/Industrial/Instrumentation 333,276 2,809 336,085 Networking 126,628 33,710 160,338 Total $ 2,405,615 $ 37,138 $ 2,442,753 For the Year Ended January 1, 2024 PCB RF&S Components Total (In thousands) End Markets: Aerospace and Defense $ 1,004,864 $ 18 $ 1,004,882 Automotive 359,455 — 359,455 Data Center Computing 318,769 51 318,820 Medical/Industrial/Instrumentation 365,611 3,448 369,059 Networking 145,347 35,004 180,351 Total $ 2,194,046 $ 38,521 $ 2,232,567 For the Year Ended January 2, 2023 PCB RF&S Components Total (In thousands) End Markets: Aerospace and Defense $ 862,367 $ — $ 862,367 Automotive 428,022 — 428,022 Data Center Computing 378,114 34 378,148 Medical/Industrial/Instrumentation 486,088 5,708 491,796 Networking 278,911 52,414 331,325 Other 4,440 ( 1,052 ) 3,388 Total $ 2,437,942 $ 57,104 $ 2,495,046 Value-Added and Sales Tax Collected from Customers As a part of the Company’s normal course of business, value-added and sales taxes are collected from customers. Such taxes collected are remitted, in a timely manner, to the appropriate governmental tax authority on behalf of the customer. Value-added and sales taxes are excluded from reported revenues and costs of goods sold presented in the consolidated statements of operations and comprehensive income (loss). Stock-Based Compensation The Company recognizes stock-based compensation expense in its consolidated financial statements for its incentive compensation plan awards. The incentive compensation plan awards include performance-based restricted stock units (PRUs), restricted stock units (RSUs), and stock options. The associated compensation expense for all awards is based on the grant date fair value of the awards. For PRUs, compensation expense also includes management’s periodic assessment of annual financial performance goals to be achieved. Compensation expense for the incentive compensation plan awards is recognized on a straight-line basis over the vesting period of the awards. The fair value of PRUs is estimated on the grant date using a Monte Carlo simulation model based on the underlying common stock closing price as of the date of grant, stock price volatility, and risk-free interest rates. The fair value of RSUs is measured on the grant date based on the quoted closing market price of the Company’s common stock. Income Taxes Income taxes are accounted for under the asset and liability method. Deferred income tax assets or liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of assets and liabilities and their respective tax bases and operating loss and tax credit carryforwards. Deferred income tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be settled or realized. The effect on deferred income tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. Deferred income tax assets are reviewed for recoverability, and the Company records a valuation allowance to reduce its deferred income tax assets when it is more likely than not that all or some portion of the deferred income tax assets will not be realized. 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 foreign subsidiaries will not be indefinitely reinvested except for certain subsidiaries, and we have established a deferred tax liability for foreign withholding taxes 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. The Company recognizes the effect of income tax positions only if those positions are more likely than not to be sustained. Recognized income tax positions are measured at the largest amount that is greater than 50 percent likely to be realized. Changes in recognition or measurement are reflected in the period in which the change in judgment occurs. Estimated interest and penalties related to underpayment of income taxes are recorded as a component of income tax provision in the consolidated statements of operations. Fair Value Measures The Company measures at fair value certain of its financial and non-financial assets and liabilities 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 levels of the fair value hierarchy are: Level 1 — Quoted market prices in active markets for identical assets or liabilities; Level 2 — Significant other observable inputs (e.g., quoted prices for similar items in active markets, quoted prices for identical or similar items in markets that are not active, inputs other than quoted prices that are observable, such as interest rate and yield curves, and market-corroborated inputs); and Level 3 — Unobservable inputs in which there is little or no market data, which require the reporting unit to develop its own assumptions. Earnings (Loss) Per Share Basic earnings (loss) per common share excludes dilution and is computed by dividing net income (loss) by the weighted average number of common shares outstanding during the period. Diluted earnings (loss) per common share reflect the potential dilution that could occur if stock options, or other common stock equivalents were exercised or converted into common stock. The dilutive effect of stock options or other common stock equivalents is calculated using the treasury stock method. Comprehensive Income (Loss) Comprehensive income (loss) includes changes to equity accounts that were not the result of transactions with stockholders. Comprehensive income (loss) is comprised of net income (loss), changes in the cumulative foreign currency translation adjustments, pension obligation adjustments, and realized and unrealized gains or losses on hedged derivative instruments. Loss Contingencies The Company establishes an accrual for an estimated loss contingency when it is both probable that an asset has been impaired or that a liability has been incurred and the amount of the loss can be reasonably estimated. Any legal fees expected to be incurred in connection with a contingency are expensed as incurred.
