Accounting Policies [Abstract]
Description of Business and Basis of Presentation	1. Description of Business and Basis of Presentation Description of Business Intevac, Inc. (together with its subsidiaries, “Intevac”, the “Company” or “we”) is a leader in the design and development of high-productivity, thin-film processing systems. Intevac’s production-proven platforms are designed for high-volume manufacturing of substrates with precise thin-film properties, such as for the hard disk drive (“HDD”) and advanced coatings (“ADVC”) (formerly known as display cover panel (“DCP”)) markets. Principles of Consolidation and Basis of Presentation The consolidated financial statements include the accounts of Intevac, Inc. and its subsidiaries after elimination of inter-company balances and transactions. The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results could differ materially from those estimates. Fiscal Year End Date Intevac operates under a 52-53 Reportable Segment During fiscal 2021, we sold the business of one of our reporting segments, Photonics. Therefore, we have one reportable segment remaining. See Note 2 for additional disclosure related to discontinued operations. The remaining segment, Thin Film Equipment (“TFE”), designs, develops and markets vacuum process equipment solutions for high-volume manufacturing of small substrates with precise thin-film properties, such as for the HDD and ADVC markets, as well as other adjacent thin-film markets. The TFE segment also previously designed, developed and marketed manufacturing equipment for the photovoltaic (“PV”) solar cell and advanced semiconductor packaging (“ASP”) industries. In March 2022, the Company’s management realigned its operational focus and eliminated several research and development (“R&D”) programs and product offerings. As part of this realignment effort, the Company ceased its efforts to develop and market several of its manufacturing platforms for the ADVC, PV and ASP industries. Discontinued Operations On December 30, 2021, the Company sold its Photonics business. Due to the sale of the Photonics business during the fourth quarter of 2021, we have classified the results of the Photonics business as discontinued operations in our consolidated statements of operations for all periods presented. All amounts included in the Notes to Consolidated Financial Statements relate to continuing operations unless otherwise noted. See Note 2. Cash, Cash Equivalents and Investments Intevac considers all highly liquid investments with original maturities of three months or less when purchased to be cash equivalents. Available-for-sale stockholders’ equity. Realized gains and losses and declines in value judged to be other than temporary, if any, on available-for-sale Restricted Cash Restricted cash of $600,000 as of December 30, 2023 secures a standby letter of credit obligation associated with a lease obligation and the restriction on the cash will be removed when the letter of credit expires. In addition, Intevac pledged $100,000 as collateral for various guarantees with its bank. Derivative Instruments and Hedging Arrangements Foreign Exchange Exposure Management re-measurement non-functional Fair Value Measurement—Definition and Hierarchy Intevac reports certain financial assets and liabilities at fair value. Intevac defines fair value as the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Fair value measurements are classified and disclosed in one of the following three categories: Level 1 Level 2 Level 3 Trade Accounts Receivable and Allowance for Credit Losses The Company’s accounts receivable are recorded at invoiced amounts less allowance for any credit losses. In accordance with the Financial Accounting Standards Board (“FASB”)’s Accounting Standards Update (“ASU”) 2016-13 that write-off Inventories Inventories are generally stated at the lower of cost or net realizable value, with cost determined on an average cost basis. Property, Plant and Equipment Equipment and leasehold improvements are stated at cost. Depreciation is computed using the straight-line method over the estimated useful lives of the assets as follows: computers and software, 3 years; machinery and equipment, 5 years; furniture, 7 years; vehicles, 4 years; and leasehold improvements, remaining lease term. Impairment of Long-Lived Assets Long-lived assets and certain identifiable finite-lived intangible assets to be held and used are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of such assets may not be recoverable. Determination of recoverability of long-lived assets is based on an estimate of undiscounted future cash flows resulting from the use of the asset and its eventual disposition. Measurement of an impairment loss for long-lived assets and certain identifiable intangible assets that management expects to hold and use is based on the fair value of the asset. When an impairment loss is recognized, the carrying amount of the asset is reduced to its estimated fair value. Acquisitions Acquisition Method. Acquisitions that meet the definition of a business under Accounting Standards Codification (“ASC”) 805, “Business Combinations,” (“ASC 805”) are accounted for using the acquisition method of accounting. Under the acquisition method of accounting, assets acquired, liabilities assumed, contractual contingencies, and contingent consideration, when applicable, are recorded at fair value at the acquisition date. Any excess of the purchase price over the fair value of the net assets acquired is recorded as goodwill. The application of the acquisition method of accounting requires management to make significant estimates and assumptions in the determination of the fair value of assets acquired and liabilities assumed in connection with the allocation of the purchase price consideration to the assets acquired and liabilities assumed. Transaction costs associated with business combinations are expensed as incurred and are included in general and administrative expense in the consolidated statements of operations. Contingent consideration, if any, is recognized and measured at fair value as of the acquisition date. Cost Accumulation Model. Acquisitions that do not meet the definition of a business under ASC 805 are accounted for as an asset acquisition, utilizing a cost accumulation model. Assets acquired and liabilities assumed are recognized at cost, which is the consideration the acquirer transfers to the seller, including direct transaction costs, on the acquisition date. The cost of the acquisition is then allocated to the assets acquired based on their relative fair values. Goodwill is not recognized in an asset acquisition. Direct transaction costs include those third-party costs that can be directly attributable to the asset acquisition and would not have been incurred absent the acquisition transaction. Contingent consideration, representing an obligation of the acquirer to transfer additional assets or equity interests to the seller if future events occur or conditions are met, is recognized when probable and reasonably estimable. Contingent consideration recognized is included in the initial cost of the assets acquired, with subsequent changes in the recorded amount of contingent consideration recognized as an adjustment to the cost basis of the acquired assets. Subsequent changes are allocated to the acquired assets based on their relative fair value. Income Taxes Intevac accounts for income taxes by recognizing deferred tax assets and liabilities using enacted tax rates for the effect of temporary differences between the book and tax bases of recorded assets and liabilities. Deferred tax assets and liabilities are recognized using enacted tax rates for the effect of temporary differences between book and tax bases of recorded assets and liabilities. Deferred tax assets are reduced by a valuation allowance if it is more likely than not that a portion of the deferred tax asset will not be realized. In determining whether to establish or maintain a valuation allowance against a deferred tax asset, the Company reviews available evidence to determine whether it is more likely than not that all or a portion of the Company’s net deferred tax assets will be realized in future periods. Consideration is given to various positive and negative factors that could affect the realization of the net deferred tax assets. In making such a determination, the Company considers, among other things, future reversals of existing taxable temporary differences, projected future taxable income, tax-planning The effective tax rate is highly dependent upon the level of Intevac’s projected earnings, the geographic composition of worldwide earnings, tax regulations governing each region, net operating loss carryforwards, availability of tax credits and the effectiveness of Intevac’s tax planning strategies. Intevac carefully monitors the changes in many factors and adjust its effective income tax rate on a timely basis. If actual results differ from the estimates, this could have a material effect on Intevac’s business, financial condition and results of operations. The calculation of tax liabilities involves significant judgment in estimating the impact of uncertainties in the application of complex tax laws. Resolution of these uncertainties in a manner inconsistent with Intevac’s expectations could have a material effect on Intevac’s business, financial condition and results of operations. Intevac recognizes accrued interest and penalties related to unrecognized tax benefits in the provision for income taxes. Sales and Value Added Taxes Taxes collected from customers and remitted to governmental authorities are presented on a net basis in the accompanying consolidated statements of operations. Revenue Recognition A majority of our equipment sales revenue, which includes systems, technology upgrades, service and spare parts is recognized when products are shipped from our manufacturing facilities. We recognize revenue for equipment sales at a point in time following the transfer of control of such products to the customer, which typically occurs upon shipment or delivery depending on the terms of the underlying contracts. Intevac recognizes revenue in certain circumstances before delivery has occurred (commonly referred to as bill and hold transactions). In such circumstances, among other things, risk of ownership has passed to the customer, the customer has made a written fixed commitment to purchase the finished goods, the customer has requested the finished goods be held for future delivery as scheduled and designated by them, and no additional performance obligations exist by Intevac. For these transactions, the finished goods are segregated from inventory and normal billing and credit terms granted. Our contracts with customers may include multiple performance obligations. For such arrangements, under the revenue standard we allocate revenue to each performance obligation based on its relative standalone selling price. We generally determine standalone selling prices based on the prices charged to customers or by using expected cost plus margin. Under the revenue standard, the expected costs associated with our base warranties are recognized as expense when the equipment is sold. Advertising Costs Advertising costs are expensed as incurred. Advertising costs were not material for all periods presented. Foreign Currency Translation The functional currency of Intevac’s foreign subsidiaries in Singapore and Hong Kong is the U.S. dollar. The functional currency of Intevac’s foreign subsidiaries in China and Malaysia is the local currency of the country in which the respective subsidiary operates. Assets and liabilities recorded in foreign currencies are translated at year-end included in stockholders’ equity as a component of accumulated other comprehensive income in the accompanying consolidated balance sheets. The effects of foreign currency transactions are included in other income (expense), net in the determination of net income. Losses from foreign currency transactions were $165,000 and $186,000 in 2023 and 2022, respectively. Comprehensive Income (Loss) The changes in accumulated other comprehensive income (loss) by component, were as follows for the years ended December 30, 2023 and December 31, 2022: Foreign currency Unrealized holding gains (losses) on available-for-sale investments Total (in thousands) Balance at January 1, 2022 $ 608 $ (30 ) $ 578 Other comprehensive loss before reclassification (331 ) (454 ) (785 ) Amounts reclassified from other comprehensive income (loss) 14 — 14 Net current-period other comprehensive loss (317 ) (454 ) (771 ) Balance at December 31, 2022 291 $ (484 ) (193 ) Other comprehensive income (loss) before reclassification (132 ) 422 290 Amounts reclassified from other comprehensive income (loss) — — — Net current-period other comprehensive income (loss) (132 ) 422 290 Balance at December 30, 2023 $ 159 $ (62 ) $ 97 Employee Stock Plans Intevac has equity-based compensation plans that provide for the grant to employees of equity-based awards, including incentive or non-statutory non-statutory non-employee Recent Accounting Pronouncements Not Yet Adopted In November 2023, the FASB issued ASU 2023-07, In December 2023, the FASB issued ASU 2023-09, We have assessed all other ASUs issued but not yet adopted and concluded that those not disclosed are not relevant to the Company or are not expected to have a material impact.

Divestiture and Discontinued Operations	2. Divestiture and Discontinued Operations Sale of Photonics On December 30, 2021, the Company entered into an asset purchase agreement (the “Purchase Agreement”) with EOTECH, LLC (“EOTECH”) governing the sale of the Company’s Photonics business to EOTECH in exchange for (i) $70.0 million in cash consideration, (ii) up to $30.0 million in earnout payments and (iii) the assumption by EOTECH of certain liabilities of the Photonics business as specified in the Purchase Agreement. The transaction closed on December 30, 2021. Under the Purchase Agreement, EOTECH also agreed to pay to the Company, if earned, earnout payments of up to an aggregate of $30.0 million based on achievement of fiscal year 2023, 2024 and 2025 Photonics segment revenue targets for the Integrated Visual Augmentation System (“IVAS”) program as specified in the Purchase Agreement. At any time prior to December 31, 2024, EOTECH may elect to pay to the Company $14.0 million, which would terminate EOTECH’s obligations with respect to any remaining earnout payments. As of December 30, 2023, there have been no earnout payments under the Purchase Agreement. The cash proceeds do not include any estimated future payments from the revenue earnout as the Company has elected to record the proceeds when the consideration is deemed realizable. The Company believes the disposition of the Photonics business will allow it to benefit from a streamlined business model, simplified operating structure, and enhanced management focus. In connection with the Photonics sale, the Company and EOTECH also entered into a Transition Service Agreement (the “TSA”) and a Lease Assignment Agreement. The TSA, which expired on June 30, 2022, outlined the information technology, people, and facility support the parties provided to each other for a period after the closing of the sale. The Lease Assignment Agreement assigns the lease obligation for two buildings in the Company’s California campus to EOTECH. As part of the assignment, the Company has agreed to subsidize a portion of EOTECH’s lease payments through the remainder of the lease term which expires in March 2024. In August 2022, Intevac and EOTECH entered into a Shared Services Agreement (the “Shared Services Agreement”) to share certain building maintenance costs. TSA fees of $989,000 were earned in fiscal 2022. The agreed-upon charges for such services were generally intended to allow the service provider to recover all costs and expenses of providing such services. The TSA and shared service fees were included in selling, general and administrative expenses and cost of sales, respectively, in the Company’s consolidated statement of operations. Additionally, during fiscal 2022, the Company sold inventory in the amount of $148,000 to EOTECH. Charges for fiscal 2023 and fiscal 2022 associated with the Shared Services Agreement were $143,000 and $40,000, respectively. Accounts receivable from EOTECH of $62,000 at December 30, 2023 and $49,000 at December 31, 2022 were included in trade and other accounts receivable in the Company’s consolidated balance sheets. Discontinued Operations Based on its magnitude and because the Company exited certain markets, the sale of the Photonics segment represents a significant strategic shift that has a material effect on the Company’s operations and financial results, and the Company has separately reported the results of its Photonics segment as discontinued operations in the consolidated statements of operations for the years ended December 30, 2023 and December 31, 2022. The operating results of the discontinued operations only reflect revenues and expenses that are directly attributable to the Photonics segment that have been eliminated from continuing operations. The key components from discontinued operations related to the Photonics segment are as follows (in thousands): Year Ended, December 30, 2023 December 31, 2022 (In thousands, except per share amounts) Operating expenses: Selling, general and administrative $ (420 ) $ 321 Total operating expenses (420 ) 321 Operating income (loss)—discontinued operations 420 (321 ) Year Ended, December 30, 2023 December 31, 2022 (In thousands, except per share amounts) Other income (expense)—discontinued operations — — Income (loss) discontinued operations before provision for (benefit from) income taxes 420 (321 ) Provision for (benefit from) income taxes — — Net income (loss) discontinued operations net of tax $ 420 $ (321 ) The cash flows related to discontinued operations have not been segregated and are included in the consolidated statements of cash flows.

For our system and certain upgrade sales, our customers generally pay in three installments, with a portion of the system price billed upon receipt of an order, a portion of the price billed upon shipment, and the balance of the price due upon completion of installation and acceptance of the system at the customer’s factory. Accounts receivable, unbilled generally represents the balance of the system price that is due upon completion of installation and acceptance less the amount that has been deferred as revenue for the performance of the installation tasks. During fiscal 2023, contract assets decreased by $31,000 primarily due to billing of spare parts that were accrued and unbilled at December 31, 2022, offset in part by the accrual of revenue for a system delivered during fiscal 2023, which was pending acceptance as of December 30, 2023 and the accrual of revenue related to spare parts sold to a customer as of December 30, 2023. Customer advances generally represent amounts billed to the customer prior to transferring goods which represents a contract liability. The Company has elected to use the practical expedient to disregard the effect of the time value of money in a significant financing component when its payment terms are less than one year. These contract advances are liquidated when revenue is recognized. Customer advances with deliveries beyond one year are included in long term liabilities. Deferred revenue generally represents amounts billed to a customer for completed systems at the customer site that are undergoing installation and acceptance testing where transfer of control has not yet occurred as Intevac does not yet have a demonstrated history of meeting the acceptance criteria upon the customer’s receipt of product and represents a contract liability. During fiscal 2023, we recognized revenue of $3.6 million and $2.2 million that was included in customer advances and deferred revenue, respectively, at the beginning of the period. In May 2023, the Company received notice of the cancellation of a $54.6 million order for eight 200 Lean HDD systems due to the customer postponing previously planned media capacity additions, and, accordingly, the Company removed the order from backlog. The customer contract associated with the cancelled order requires the customer to pay the Company a prorated price based upon the percentage of work completed on the order. The Company has received customer advances in the amount of $19.1 million associated with the cancelled order, all of which will be utilized to settle this customer obligation. In September 2023, the Company applied $444,000 of billings against these advances in connection with inventory scrapped at the customer’s direction. In December 2023, the Company received notice of the cancellation of a $11.4 million order for two 200 Lean HDD systems due to the customer postponing previously planned media capacity additions, and, accordingly, the Company removed the order from backlog. The Company has not received any customer advances associated with the cancelled order. The Company expects to invoice the customer in the first quarter of fiscal 2024 for the cancellation fee associated with this order. On December 30, 2023, we had $42.4 million of remaining performance obligations, which we also refer to as backlog and expect to recognize as revenue: 79% in 2024 and 21% in 2025.

Equity-Based Compensation

Equity-Based Compensation	Dec. 30, 2023
Disclosure Of Compensation Related Costs Sharebased Payments [Abstract]
Equity-Based Compensation	4. Equity-Based Compensation Intevac accounts for share-based awards in accordance with the provisions of the accounting guidance which requires the measurement and recognition of compensation expense for all share-based payment awards made to employees, consultants and directors based upon the grant-date fair value of those awards. The estimated fair value of Intevac’s equity-based awards is amortized over the awards’ service periods using the graded vesting attribution method. Descriptions of Plans Equity Incentive Plans At December 30, 2023, Intevac had equity-based awards outstanding under the 2020 Equity Incentive Plan and the 2012 Equity Incentive Plan (the “Plans”) and the 2003 Employee Stock Purchase Plan (the “ESPP”). Intevac’s stockholders approved all of these plans. The Plans are a broad-based, long-term retention program intended to attract and retain qualified management and employees, and align stockholder and employee interests. The Plans permit the grant of incentive or non-statutory On January 19, 2022, the Board of Directors adopted the 2022 Inducement Equity Incentive Plan (the “Inducement Plan”) and, subject to the adjustment provisions of the Inducement Plan, reserved 1,200,000 shares of the Company’s common stock for issuance pursuant to equity awards granted under the Inducement Plan. The Inducement Plan provides for the grant of equity-based awards, including nonstatutory stock options, restricted stock units, restricted stock, stock appreciation rights, performance shares and performance units, and its terms are substantially similar to the Company’s 2020 Equity Incentive Plan. The Inducement Plan was adopted without stockholder approval pursuant to Rule 5635(c)(4) of the Nasdaq Listing Rules. In accordance with that rule, awards under the Inducement Plan may only be made to individuals not previously employees or non-employee directors of non-employment with 2003 Employee Stock Purchase Plan The ESPP provides that eligible employees may purchase Intevac’s common stock through payroll deductions at a price equal to 85% of the lower of the fair market value at the entry date of the applicable offering period or at the end of each applicable purchase interval. Offering periods are generally two years in length, and consist of a series of six-month six-month The effect of recording equity-based compensation for fiscal 2023 and 2022 was as follows (in thousands): 2023 2022 Equity-based compensation by type of award: Stock options $ (14 ) $ (156 ) RSUs 2,154 2,184 PRSUs 1,592 2,379 Employee stock purchase plan 641 483 Total equity-based compensation $ 4,373 $ 4,890 Included in the table above: (a) A reversal of $462,000 in equity-based compensation expense related to forfeitures of awards due to our 2023 cost reduction plan for fiscal 2023. A reversal of $1.3 million in equity-based compensation expense related to forfeitures of awards due to our 2022 cost reduction plan and a $37,000 benefit related to the modification of certain stock-based awards for fiscal 2022. (See Note 13. Restructuring and Other Costs, Net); and (b) Equity-based compensation reported in discontinued operations of ($260,000) for fiscal 2023, and ($229,000) for fiscal 2022. Equity-based compensation expense allocated to discontinued operations for fiscal 2022 includes $75,000 related to the modification of certain stock-based awards and is net of a divestiture-related forfeiture benefit of $446,000 that was recognized when employees were conveyed to EOTECH upon closing of the Photonics divestiture. (See Note 2. Divestiture and Discontinued Operations.) Equity-based compensation expense is based on awards which vest. Intevac accounts for forfeitures as they occur, rather than estimating expected forfeitures. Stock Options The exercise price of each stock option equals the market price of Intevac’s stock on the date of grant. Most options are scheduled to vest over three The computation of the expected volatility assumption used in the Black-Scholes calculations for new grants is based on historical volatility of Intevac’s stock price. The risk-free interest rate is based on the yield available on U.S. Treasury Strips with an equivalent remaining term. The expected life of employee stock options represents the weighted-average period that the stock options are expected to remain outstanding and was determined based on historical experience of similar awards, giving consideration to the contractual terms of the stock-based awards and vesting schedules. The dividend yield assumption is based on Intevac’s history of not paying dividends and the assumption of not paying dividends in the future. The Company did not grant any stock options in fiscal 2023 and fiscal 2022. A summary of the stock option activity is as follows: Shares Weighted Exercise Weighted Average Aggregate Intrinsic Value Options outstanding at December 31, 2022 383,099 $ 7.07 2.40 $ 327,711 Options cancelled and forfeited (188,286 ) $ 7.97 Options exercised (52,813 ) $ 5.15 Options outstanding at December 30, 2023 142,000 $ 6.57 1.57 $ 900 Options exercisable at December 30, 2023 141,750 $ 6.58 1.57 $ 675 The total intrinsic value of options exercised during fiscal years 2023 and 2022 was $99,000 and $206,000, respectively. At December 30, 2023, Intevac had no unrecognized compensation expense related to stock options. RSUs A summary of the RSU activity is as follows: Shares Weighted Grant Date Fair Value Weighted Average Aggregate Value Non-vested 1,309,792 $ 5.14 1.21 $ 8,474,354 Granted 452,444 $ 4.66 Vested (584,627 ) $ 5.16 Cancelled (262,522 ) $ 5.12 Non-vested 915,087 $ 4.89 1.04 $ 3,953,176 Time-based RSUs are converted into shares of Intevac common stock upon vesting on a one-for-one three Intevac common stock on the date of the grant, and the compensation expense is recognized over the vesting period. At December 30, 2023, Intevac had $2.0 million of total unrecognized compensation expense related to RSUs that will be recognized over the weighted-average period of 1.04 years. A summary of the PRSU activity is as follows: Shares Weighted Grant Date Fair Value Weighted Average Aggregate Value Non-vested 1,089,339 $ 3.54 0.49 $ 7,048,023 Granted 525,656 $ 4.92 Vested (190,903 ) $ 4.26 Cancelled (263,799 ) $ 3.57 Non-vested 1,160,293 $ 4.04 1.99 $ 5,012,466 At December 30, 2023, Intevac had $2.0 million of total unrecognized compensation expense related to PRSUs that will be recognized over the weighted-average period of 1.16 years. In May 2023, we granted to members of our senior management awards of performance-based restricted stock units (the “2023 PRSU Awards”) covering an aggregate of 525,656 shares of Intevac common stock (at maximum performance). The 2023 PRSU Awards are eligible to be earned based on achievement of five strategic goals during a three-year performance period commencing on May 18, 2023 and ending on May 31, 2026 (the “2023-2026 Performance Period”). The 2023 PRSU Awards will vest, if at all, in five possible tranches. Each of the five tranches will vest only if the applicable strategic goal is achieved within the 2023-2026 Performance Period, and each tranche may only be achieved once during the 2023-2026 Performance Period. If a strategic goal is not achieved within the 2023-2026 Performance Period, the corresponding PRSUs will not vest, and all unvested PRSUs at the end of the 2023-2026 Performance Period will immediately be forfeited. Stock compensation expense is recorded based on the probability of achievement of the performance conditions specified in the PRSU grant. The Company evaluated the strategic goals in the context of its current long-range financial plan and its product development roadmap and determined the probability of achieving each goal for accounting purposes commencing in the quarter granted. Management expectations related to the achievement of performance goals associated with PRSUs with performance conditions are assessed regularly to determine whether such grants are expected to vest. The fair value of each PRSU is the Company’s stock price on the date of grant. Over the 2023-2026 Performance Period, the number of shares expected to be issued may be adjusted upward or downward based upon the probability of achievement of the performance conditions. In fiscal 2022, we granted to members of our senior management awards of PRSUs (“2022 PRSU Awards”) covering an aggregate of 1.2 million shares of Intevac common stock (at maximum performance). The 2022 PRSU Awards are eligible to be earned based on achievement of certain stock prices based on the average closing price of the Company’s stock over a 30-day Intevac estimated the weighted-average fair value of 2022 PRSU Awards using the following weighted-average assumptions: 2022 Weighted-average fair value of grants per share $ 3.58 Expected volatility 56.70 % Risk-free interest rate 3.11 % Dividend yield None ESPP The fair value of the employee stock purchase right is estimated on the date of grant using the Black-Scholes option pricing model with the following weighted-average assumptions: 2023 2022 Stock Purchase Rights: Weighted-average fair value of grants per share $ 0.91 $ 1.26 Expected volatility 40.33 % 52.57 % Risk free interest rate 5.15 % 1.94 % Expected term of purchase rights (in years) 1.08 1.24 Dividend yield None None The expected life of purchase rights is the period of time remaining in the current offering period.

Risks and Uncertainties [Abstract]
Concentrations	6. Concentrations Credit Risk and Significant Customers Financial instruments that potentially subject the Company to significant concentrations of credit risk consist of cash equivalents, short- and long-term investments, restricted cash, and accounts receivable. Intevac generally invests its excess cash in money market funds, certificates of deposit, commercial paper, obligations of the U.S. government and its agencies, corporate debt securities, asset backed securities and municipal bonds. The Company has adopted an investment policy and established guidelines relating to credit quality, diversification and maturities of its investments in order to preserve principal and maintain liquidity. All investment securities in Intevac’s portfolio have an investment grade credit rating. Intevac’s accounts receivable tend to be concentrated in a limited number of customers. The following customer accounted for at least 10 percent of Intevac’s accounts receivable at December 30, 2023 and December 31, 2022. 2023 2022 Seagate Technology 95 % 88 % Intevac’s largest customers tend to change from period to period. Historically, a significant portion of Intevac’s revenues in any particular period have been attributable to sales to a limited number of customers. Intevac performs credit evaluations of its customers’ financial condition and generally requires deposits on system orders but does not generally require collateral or other security to support customer receivables. The following customers accounted for at least 10 percent of Intevac’s consolidated net revenues in fiscal 2023 and/or 2022. 2023 2022 Seagate Technology 92 % 80 % Western Digital Corporation * 18 % * Less than 10% Products Disk manufacturing products contributed a significant portion of Intevac’s revenues in fiscal 2023 and 2022. Intevac expects that the ability to maintain or expand its current levels of revenues in the future will depend upon continuing market demand for its products; its success in enhancing its existing systems and developing and manufacturing competitive disk manufacturing equipment, such as the 200 Lean; its success in utilizing Intevac’s expertise in complex manufacturing equipment to develop and sell new manufacturing equipment products for ADVC.

This investment manager performs a review of the pricing methodologies and inputs utilized by the independent pricing services for each asset type priced by the vendor. In addition, on at least an annual basis, the investment manager conducts due diligence visits and interviews with each pricing vendor to verify the inputs utilized for each asset class. The due diligence visits include a review of the procedures performed by each vendor to ensure that pricing evaluations are representative of the price that would be received to sell a security in an orderly transaction. Any pricing where the input is based solely on a broker price is deemed to be a Level 3 price.

Management assesses the available positive and negative evidence to estimate if sufficient future taxable income will be generated to use the existing deferred tax assets. In fiscal 2014, a valuation allowance of $9.4 million was established to record the portion of the Singapore deferred tax assets that more likely than not will not be realized. The Company concluded that, as of December 29, 2018, it is more likely than not that the Company will generate sufficient taxable income in Singapore to realize its deferred tax assets and reversed the valuation allowance during the fourth quarter of 2018. This reversal resulted in the recognition of a non-cash In fiscal 2012, a valuation allowance of $23.4 million was established to record the portion of the U.S. federal deferred tax asset that more likely than not will not be realized. For fiscal 2023 a valuation allowance increase of $321,000 and for fiscal 2022 a valuation allowance increase of $3.1 million were recorded for the U.S. federal deferred tax assets. A valuation allowance is recorded against the entire state deferred tax assets, which consists of state income tax temporary differences and deferred research and other tax credits that are not realizable in the foreseeable future. As of December 30, 2023, our federal, foreign and state net operating loss carryforwards for income tax purposes were approximately $43.4 million, $18.6 million and $112.1 million, respectively. The federal and state net operating loss carryforwards are subject to various limitations under Section 382 of the Internal Revenue Code and applicable state tax laws. If not utilized, the federal net operating loss carryforwards and the state net operating loss carryforwards will begin to expire in 2034 and 2028, respectively. The foreign net operating loss carryforwards do not expire. As of December 30, 2023, our federal and state tax credit carryforwards for income tax purposes were approximately $18.9 million and $13.4 million, respectively. If not utilized, the federal tax credit carryforwards will begin to expire in 2024 and the state tax credits carry forward indefinitely. We account for Global Intangible Low-Taxed On August 16, 2022, the Inflation Reduction Act of 2022 (“IRA”) was signed into U.S. law. The IRA includes implementation of a new alternative minimum tax, an excise tax on stock buybacks, and significant tax incentives for energy and climate initiatives, among other provisions. The Company is evaluating the provisions included under the IRA and does not expect the provisions to have a material impact to the Company’s consolidated financial statements. A provision of the Tax Cuts and Jobs Act (“TCJA”) took effect on January 1, 2022 that amended Section 174 to require capitalization and amortization of research and experimental (“R&E”) expenditures and software development costs. The capitalized R&E and software development costs associated with research conducted in the United States is amortized ratably over a 5-year (15-year The difference between the tax provision at the statutory federal income tax rate and the tax provision for fiscal 2023 and 2022 on continuing operations was as follows (in thousands): 2023 2022 Income tax (benefit) at the federal statutory rate $ (2,266 ) $ (3,240 ) State income taxes, net of federal benefit 3 4 Change in valuation allowance: U.S 321 3,129 Foreign — — Effect of foreign operations taxed at various rates (266 ) (219 ) Research tax credits (1,009 ) (788 ) Effect of tax rate changes, permanent differences and adjustments of prior deferrals 5,039 2,441 Unrecognized tax benefits — — Total provision for income taxes on continuing operations $ 1,822 $ 1,327 Intevac has not provided for foreign withholding taxes on approximately $1.9 million of undistributed earnings from non-U.S. The total amount of gross unrecognized tax benefits was $7.6 million as of December 30, 2023, none of which would affect Intevac’s effective tax rate if realized. The aggregate changes in the balance of gross unrecognized tax benefits were as follows for fiscal 2023 and 2022: 2023 2022 Beginning balance $ 730 $ 718 Additions based on tax positions related to the current year 430 12 Increases for tax positions of prior years 6,448 — Lapse of statute of limitations (9 ) — Ending balance $ 7,599 $ 730 The Company does not anticipate any changes in the amount of unrecognized tax benefits in the next twelve months. It is Intevac’s policy to include interest and penalties related to unrecognized tax benefits in the provision for income taxes on the consolidated statements of operations. During fiscal 2023 and 2022, Intevac recognized a net tax expense (benefit) of $0. As of December 30, 2023, Intevac did not have any accrued interest related to unrecognized tax benefits. Intevac did not accrue any penalties related to these unrecognized tax benefits because Intevac has other tax attributes which would offset any potential taxes due. Intevac is subject to income taxes in the U.S. federal jurisdiction, and various state and foreign jurisdictions. Tax regulations within each jurisdiction are subject to the interpretation of the related tax laws and regulations and require significant judgment to apply. As of December 30, 2023, all of the tax years remained open to examination by the federal and state taxing authorities, for three The Inland Revenue Authority of Singapore (“IRAS”) conducted a review of the fiscal 2017 through 2019 tax returns of the Company’s wholly-owned subsidiary, Intevac Asia Pte. Ltd. IRAS had challenged the Company’s tax position with respect to certain aspects of the Company’s transfer pricing. The IRAS has concluded their audit and notified us on January 18, 2024 that there are no adjustments to our tax returns for years 2017 through 2019. Presently, there are no other active income tax examinations in the jurisdictions where Intevac operates.

Commitments and Contingencies	12. Commitments and Contingencies Leases Intevac leases certain manufacturing facilities, warehouses, office space, and equipment under non-cancelable The Company and EOTECH have entered into a Lease Assignment Agreement that assigns a portion of the Company’s lease obligation regarding its Santa Clara, California campus to EOTECH. The Company is contingently liable should EOTECH default on future lease obligations through the lease termination date of March 2024. The aggregate amount of the future lease obligations under this arrangement is $293,000 as of December 30, 2023. As the Company is not being released as the primary obligor under the original lease, the lease assignment has been accounted for as a sublease. In consideration of EOTECH’s assumption of the above-mentioned lease obligations, which assumed lease obligations pertain in part to excess space beyond that required for EOTECH’s currently anticipated operation of the Photonics business, the Company agreed to pay to EOTECH the amount of $2.1 million (the “Unused Space Amount”), which Unused Space Amount was payable in (i) one initial installment of $308,000 on January 10, 2022 and (ii) seven (7) equal quarterly installments of $259,000. The final payment was made in October 2023. The following table reflects our lease assets and our lease liabilities at December 30, 2023 and December 31, 2022.

These indemnification obligations are valid as long as the director or officer acted in good faith and in a manner the person reasonably believed to be in, or not opposed to, the best interests of the Company and, with respect to any criminal action or proceeding, had no reasonable cause to believe his or her conduct was unlawful. The maximum potential amount of future payments Intevac could be required to make under these indemnification obligations is unlimited; however, Intevac has a director and officer insurance policy that mitigates Intevac’s exposure and enables Intevac to recover a portion of any future amounts paid. As a result of Intevac’s insurance policy coverage, Intevac believes the estimated fair value of these indemnification obligations is not material. Other Indemnifications As is customary in Intevac’s industry, many of Intevac’s contracts provide remedies to certain third parties such as defense, settlement, or payment of judgments for intellectual property claims related to the use of its products. Such indemnification obligations may not be subject to maximum loss clauses. Historically, payments made related to these indemnifications have been immaterial. Letters of Credit As of December 30, 2023, we had letters of credit and bank guarantees outstanding totaling $700,000, including the standby letter of credit outstanding under the Santa Clara, California facility lease and various other guarantees with its bank. These letters of credit and bank guarantees are collateralized by $700,000 of restricted cash. Warranty Intevac provides for the estimated cost of warranty when revenue is recognized. Intevac’s warranty is subject to contract terms and, for its systems, the warranty typically ranges between 12 and 24 months from customer acceptance. During this warranty period any defective non-consumable On the consolidated balance sheets, the short-term portion of the warranty provision is included in other accrued liabilities, while the long-term portion is included in other long-term liabilities. The expense associated with product warranties issued or adjusted is included in cost of net revenues on the consolidated statements of operations. The following table displays the activity in the warranty provision account for fiscal 2023 and 2022: 2023 2022 (in thousands) Beginning balance $ 163 $ 346 Expenditures incurred under warranties (214 ) (312 ) Accruals for product warranties 262 147 Adjustments to previously existing warranty accruals (6 ) (18 ) Ending balance $ 205 $ 163 Legal Matters From time to time, Intevac receives notification from third parties, including customers and suppliers, seeking indemnification, litigation support, payment of money or other actions in connection with claims made against them. In addition, from time to time, Intevac receives notification from third parties claiming that Intevac may be or is infringing their intellectual property or other rights. Intevac also is subject to various other legal proceedings and claims, both asserted and unasserted, that arise in the ordinary course of business. Although the outcome of these claims and proceedings cannot be predicted with certainty, Intevac does not believe that any of these other existing proceedings or claims will have a material adverse effect on its consolidated financial condition or results of operations. In July 2020, Robin Quiusky, a former contract employee who worked for us via a staffing agency, filed an action against us under the Private Attorneys General Act (“PAGA”) in California state court (Quiusky v. Intevac, Inc., et al) alleging that the Company failed to provide rest and meal breaks, pay overtime and reimburse business expenses for non-exempt

Restructuring Charges	13. Restructuring Charges During the third quarter of fiscal 2023, Intevac substantially completed implementation of a cost reduction plan (the “2023 Cost Reduction Plan”), which is intended to reduce expenses by reducing our workforce by 23 percent including employees and contractors. Intevac incurred restructuring costs of $2.0 million in severance, $2,000 in stock-based compensation associated with the modification of certain stock-based awards and other employee-related expenses associated with the 2023 Cost Reduction Plan. Additionally, as part of the 2023 Cost Reduction Plan the Company incurred a benefit of $462,000 related to the stock-based compensation forfeitures related to the employees affected by the reduction in workforce. Substantially all cash outlays in connection with the 2023 Cost Reduction Plan occurred in the third quarter of fiscal 2023. The cost of implementing the 2023 Cost Reduction Plan was reported under cost of net revenues and operating expenses in the consolidated statements of operations. Implementation of the 2023 Cost Reduction Plan is expected to reduce salary, wages and other employee-related expenses and contractor payments by approximately $4.6 million on an annual basis. During the first quarter of fiscal 2022, Intevac substantially completed implementation of the 2022 cost reduction plan (the “2022 Cost Reduction Plan”), which was intended to reduce our overall cost structure and optimize our operational design, inclusive of the stranded overhead associated with the divestiture of the Photonics business. The restructuring program includes management reorganization and the right sizing of certain technology development, marketing and administrative functions. We incurred restructuring costs of $1.2 million in estimated severance and the related modification of certain stock-based awards. Other costs incurred as part of the 2022 Cost Reduction Plan include: (i) a benefit of $1.3 million related to the stock-based compensation forfeitures related to the employees affected by the reduction in workforce, (ii) $1.5 million for fixed asset disposals and (iii) $755,000 for write-offs of excess inventory. The 2022 Cost Reduction Plan reduced the workforce by 6 percent. The cost of implementing the 2022 Cost Reduction Plan was reported under cost of net revenues and operating expenses in the consolidated statements of operations. Implementation of the 2022 Cost Reduction Plan reduced salary, wages and other employee-related expenses by approximately $2.1 million on an annual basis. During the fourth quarter of fiscal 2021, the Company recorded asset impairment and restructuring charges associated with the sale of the Photonics division including (i) $693,000 in severance and other employee-related costs related to the termination of the Photonics general manager; (ii) $1.2 million in asset impairment charges on the Company’s ROU asset and (iii) $665,000 in accruals for common area charges associated with an unused space commitment to EOTECH. In consideration of EOTECH’s assumption of certain lease obligations related to the Company’s Santa Clara, California campus, which assumed lease obligations pertain in part to excess space beyond that required EOTECH’s currently anticipated operation of the Photonics division, the Company agreed to pay EOTECH the amount of $2.1 million, which is payable in (i) one initial installment of $308,000 on January 10, 2022 and (ii) seven equal quarterly installments of $259,000. The Company recorded an asset impairment charge against its ROU asset in the amount of $1.2 million associated with the excess space noted above. The Company recorded a liability to EOTECH in the amount of $665,000, the amount related to common area charges which are not included in the base rental payments or the lease liability on the Company’s consolidated balance sheets.

Contingent Consideration	15. Acquisition of Hia, Inc. On August 26, 2022 (the “Closing Date”), the Company completed the acquisition of Hia, Inc., a supplier of magnetic bars, to bring the manufacturing of these magnetic bars in-house The Company determined this transaction represented an asset acquisition as substantially all of the value was in the technology intangible assets of Hia. Contingent consideration is not recorded in an asset acquisition until the contingency is resolved (when the contingent consideration is paid or becomes payable) or when probable and reasonably estimable. The first milestone was achieved and contingent consideration in the amount of $250,000 was paid on January 17, 2023 and was accrued in the fourth quarter of 2022. Upon recognition, the amount, including the tax effect of $67,000, is included in the measurement of the acquired asset. The technology intangible assets are being amortized on a straight-line basis over a period of 8.3 years. Total amortization expense during fiscal 2023 and fiscal 2022 was $136,000 and $42,000, respectively. Annual amortization expense related to the acquired technology intangible assets in each of the succeeding years is estimated to be approximately $136,000 per year from fiscal 2024 through fiscal 2030. The Hia acquisition was treated for tax purposes as a nontaxable transaction and, as such, the historical tax bases of the acquired assets and assumed liabilities, net operating losses, and other tax attributes of Hia will carryover.

Principles of Consolidation and Basis of Presentation	Principles of Consolidation and Basis of Presentation The consolidated financial statements include the accounts of Intevac, Inc. and its subsidiaries after elimination of inter-company balances and transactions. The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results could differ materially from those estimates.

Reportable Segment	Reportable Segment During fiscal 2021, we sold the business of one of our reporting segments, Photonics. Therefore, we have one reportable segment remaining. See Note 2 for additional disclosure related to discontinued operations. The remaining segment, Thin Film Equipment (“TFE”), designs, develops and markets vacuum process equipment solutions for high-volume manufacturing of small substrates with precise thin-film properties, such as for the HDD and ADVC markets, as well as other adjacent thin-film markets. The TFE segment also previously designed, developed and marketed manufacturing equipment for the photovoltaic (“PV”) solar cell and advanced semiconductor packaging (“ASP”) industries. In March 2022, the Company’s management realigned its operational focus and eliminated several research and development (“R&D”) programs and product offerings. As part of this realignment effort, the Company ceased its efforts to develop and market several of its manufacturing platforms for the ADVC, PV and ASP industries.
Discontinued Operations	Discontinued Operations On December 30, 2021, the Company sold its Photonics business.

Impairment of Long-Lived Assets	Impairment of Long-Lived Assets Long-lived assets and certain identifiable finite-lived intangible assets to be held and used are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of such assets may not be recoverable. Determination of recoverability of long-lived assets is based on an estimate of undiscounted future cash flows resulting from the use of the asset and its eventual disposition. Measurement of an impairment loss for long-lived assets and certain identifiable intangible assets that management expects to hold and use is based on the fair value of the asset. When an impairment loss is recognized, the carrying amount of the asset is reduced to its estimated fair value.

Acquisitions that meet the definition of a business under Accounting Standards Codification (“ASC”) 805, “Business Combinations,” (“ASC 805”) are accounted for using the acquisition method of accounting. Under the acquisition method of accounting, assets acquired, liabilities assumed, contractual contingencies, and contingent consideration, when applicable, are recorded at fair value at the acquisition date. Any excess of the purchase price over the fair value of the net assets acquired is recorded as goodwill. The application of the acquisition method of accounting requires management to make significant estimates and assumptions in the determination of the fair value of assets acquired and liabilities assumed in connection with the allocation of the purchase price consideration to the assets acquired and liabilities assumed. Transaction costs associated with business combinations are expensed as incurred and are included in general and administrative expense in the consolidated statements of operations. Contingent consideration, if any, is recognized and measured at fair value as of the acquisition date. Cost Accumulation Model. Acquisitions that do not meet the definition of a business under ASC 805 are accounted for as an asset acquisition, utilizing a cost accumulation model. Assets acquired and liabilities assumed are recognized at cost, which is the consideration the acquirer transfers to the seller, including direct transaction costs, on the acquisition date. The cost of the acquisition is then allocated to the assets acquired based on their relative fair values. Goodwill is not recognized in an asset acquisition. Direct transaction costs include those third-party costs that can be directly attributable to the asset acquisition and would not have been incurred absent the acquisition transaction. Contingent consideration, representing an obligation of the acquirer to transfer additional assets or equity interests to the seller if future events occur or conditions are met, is recognized when probable and reasonably estimable. Contingent consideration recognized is included in the initial cost of the assets acquired, with subsequent changes in the recorded amount of contingent consideration recognized as an adjustment to the cost basis of the acquired assets. Subsequent changes are allocated to the acquired assets based on their relative fair value.
Income Taxes	Income Taxes Intevac accounts for income taxes by recognizing deferred tax assets and liabilities using enacted tax rates for the effect of temporary differences between the book and tax bases of recorded assets and liabilities. Deferred tax assets and liabilities are recognized using enacted tax rates for the effect of temporary differences between book and tax bases of recorded assets and liabilities. Deferred tax assets are reduced by a valuation allowance if it is more likely than not that a portion of the deferred tax asset will not be realized. In determining whether to establish or maintain a valuation allowance against a deferred tax asset, the Company reviews available evidence to determine whether it is more likely than not that all or a portion of the Company’s net deferred tax assets will be realized in future periods. Consideration is given to various positive and negative factors that could affect the realization of the net deferred tax assets. In making such a determination, the Company considers, among other things, future reversals of existing taxable temporary differences, projected future taxable income, tax-planning The effective tax rate is highly dependent upon the level of Intevac’s projected earnings, the geographic composition of worldwide earnings, tax regulations governing each region, net operating loss carryforwards, availability of tax credits and the effectiveness of Intevac’s tax planning strategies. Intevac carefully monitors the changes in many factors and adjust its effective income tax rate on a timely basis. If actual results differ from the estimates, this could have a material effect on Intevac’s business, financial condition and results of operations. The calculation of tax liabilities involves significant judgment in estimating the impact of uncertainties in the application of complex tax laws. Resolution of these uncertainties in a manner inconsistent with Intevac’s expectations could have a material effect on Intevac’s business, financial condition and results of operations. Intevac recognizes accrued interest and penalties related to unrecognized tax benefits in the provision for income taxes.
Sales and Value Added Taxes	Sales and Value Added Taxes Taxes collected from customers and remitted to governmental authorities are presented on a net basis in the accompanying consolidated statements of operations.
Revenue Recognition	Revenue Recognition A majority of our equipment sales revenue, which includes systems, technology upgrades, service and spare parts is recognized when products are shipped from our manufacturing facilities. We recognize revenue for equipment sales at a point in time following the transfer of control of such products to the customer, which typically occurs upon shipment or delivery depending on the terms of the underlying contracts. Intevac recognizes revenue in certain circumstances before delivery has occurred (commonly referred to as bill and hold transactions). In such circumstances, among other things, risk of ownership has passed to the customer, the customer has made a written fixed commitment to purchase the finished goods, the customer has requested the finished goods be held for future delivery as scheduled and designated by them, and no additional performance obligations exist by Intevac. For these transactions, the finished goods are segregated from inventory and normal billing and credit terms granted. Our contracts with customers may include multiple performance obligations. For such arrangements, under the revenue standard we allocate revenue to each performance obligation based on its relative standalone selling price. We generally determine standalone selling prices based on the prices charged to customers or by using expected cost plus margin. Under the revenue standard, the expected costs associated with our base warranties are recognized as expense when the equipment is sold.
Advertising Costs	Advertising Costs Advertising costs are expensed as incurred. Advertising costs were not material for all periods presented.
Foreign Currency Translation	Foreign Currency Translation The functional currency of Intevac’s foreign subsidiaries in Singapore and Hong Kong is the U.S. dollar.
