Accounting Policies [Abstract]
DESCRIPTION OF THE BUSINESS, BASIS OF PRESENTATION, AND SUMMARY ACCOUNTING POLICIES	1. Description of the Business, Basis of Presentation, and Summary of Significant Accounting Policies Holley Inc., a Delaware corporation headquartered in Bowling Green, Kentucky (the “Company” or “Holley”), conducts operations through its wholly-owned subsidiaries. These operating subsidiaries are comprised of Holley Performance Products Inc. (“Holley Performance”), Hot Rod Brands, Inc. (“Hot Rod Brands”), Simpson Safety Solutions, Inc., B&M Racing and Performance Products, Inc., and Speedshop.com, Inc. Investment funds managed by Sentinel Capital Partners hold a controlling interest in Holley. On July 16, 2021, (the “Closing” and such date, the “Closing Date”) the Company consummated the business combination (the “Business Combination”) pursuant to that certain Agreement and Plan of Merger dated March 11, 2021 (the “Merger Agreement”), by and among Empower Ltd., (“Empower”), Empower Merger Sub I Inc. (“Merger Sub I”), Empower Merger Sub II LLC (“Merger Sub II”), and Holley Intermediate Holdings, Inc. (“Holley Intermediate”). On the Closing Date, Empower changed its name to Holley Inc. See Note 2, “ Business Combination and Acquisitions,” for more information. Holley Intermediate, the predecessor to Holley, was incorporated on October 25, 2018 to effect the merger of Driven Performance Brands, Inc. (“Driven”) and the purchase of High Performance Industries, Inc. (“HPI”). The Company designs, manufactures and distributes performance automotive products to customers primarily in the United States, Canada and Europe. The Company is a leading manufacturer of a diversified line of performance automotive products, including carburetors, fuel pumps, fuel injection systems, nitrous oxide injection systems, superchargers, exhaust headers, mufflers, distributors, ignition components, engine tuners and automotive performance plumbing products that are produced through its two major subsidiaries, Holley Performance and Hot Rod Brands. The Company is also a leading manufacturer of exhaust products as well as shifters, converters, transmission kits, transmissions, tuners and automotive software. The Company’s products are designed to enhance street, off-road, recreational and competitive vehicle performance through increased horsepower, torque and drivability. The Company has locations in North America, Canada, Italy and China. Emerging Growth Company Status Section 102(b)(1) of the Jumpstart Our Business Startups Act of 2012 (“JOBS Act”), exempts emerging growth companies from being required to comply with new or revised financial accounting standards until private companies are required to comply with the new or revised financial accounting standards. The JOBS Act provides that a company can elect to opt out of the extended transition period and comply with the requirements that apply to non-emerging growth companies but any such election to opt out is irrevocable. The Company is an emerging growth company, and, as such, has elected to take advantage of the benefits of the extended transition period for new or revised financial accounting standards. Risks and Uncertainties COVID-19 has adversely impacted global supply chain and general economic conditions. The Company has experienced disruptions and higher costs in manufacturing, supply chain, logistical operations, and shortages of certain Company products in distribution channels. The full extent of the impact of the COVID-19 pandemic on the Company's business and operational and financial performance and condition is currently uncertain and will depend on many factors outside the Company's control, including but not limited to the timing, extent, duration and effects of the virus and any of its mutations, the utilization and effectiveness of treatments and vaccines, the imposition of effective public safety and other protective measures, the further impact of COVID-19 on the global economy and demand for the Company's products and services. Should the COVID-19 pandemic, including variants such as Delta and Omicron, not improve or worsen, or if the Company's attempt to mitigate its impact on its supply chain, operations and costs is not successful, the Company's business, results of operations, financial condition and prospects may be adversely affected. Basis of Presentation The accompanying consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America ("U.S. GAAP" or “GAAP”) and include the accounts of the Company and its wholly-owned subsidiaries. All significant intercompany transactions and accounts have been eliminated in consolidation. Summary of Significant Accounting Policies Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates. These estimates require the use of judgment as future events and the effect of these events cannot be predicted with certainty. The estimates will change as new events occur, as more experience is acquired and as more information is obtained. The Company evaluates and updates assumptions and estimates on an ongoing basis and may consult outside experts to assist as considered necessary. Cash and Cash Equivalents Cash and cash equivalents include cash and deposits with financial institutions with original maturities less than 90 days. The Federal Deposit Insurance Corporation insures financial institution deposits up to $ 250 . The Company maintains deposits exceeding $250 in certain accounts at financial institutions. At December 31, 2021 and 2020, the Company had cash in foreign bank accounts of $ 5,765 and $ 4,607 , respectively. Accounts Receivable and Allowance for Credit Losses Accounts receivable represent amounts due from customers in the ordinary course of business. The receivables are stated at the amount management expects to collect. The Company is subject to risk of loss from uncollectible receivables in excess of its allowance. The Company maintains an allowance for credit losses for estimated losses from customers’ inability to make required payments. In order to estimate the appropriate level of this allowance, the Company analyzes historical bad debts, customer concentrations, current customer credit worthiness, current economic trends and changes in customer payment patterns. Accounts are written off when management determines the account is uncollectable. Interest is not charged on past due accounts. Inventory Valuation The Company's inventories are stated at the lower of cost or net realizable value using the first-in, first-out (FIFO) method. Adjustments to reduce the cost of inventory to its net realizable value are made, if required, for estimated excess, obsolescence or impaired balances. Segments The Company's operations are managed and reported to its Chief Executive Officer (“CEO”), the Company’s chief operating decision maker, on a consolidated basis. The CEO assesses performance and allocates resources based on the consolidated results of operations. Under this organizational and reporting structure, the Company has one reportable segment. Goodwill Goodwill represents the excess of purchase price over the fair value of the net assets of businesses acquired. On an annual basis or whenever events or changes in circumstances indicate the carrying value of goodwill may have been impaired, the Company may perform a qualitative assessment to determine if it is more likely than not that the fair value of the reporting unit is less than its carrying amount, including goodwill. If the Company determines that the fair value of the reporting unit is less than its carrying amount or elects not to perform a qualitative assessment, it will perform a quantitative analysis; otherwise, no further evaluation is necessary. For the quantitative impairment assessment, the Company compares the fair value of the reporting unit to its carrying value, including goodwill. The Company determines the fair value of the reporting unit based on a weighting of income and market approaches. If the fair value of the reporting unit exceeds the carrying value of the net assets assigned to that unit, goodwill is not impaired and no further testing is performed. If the carrying value of the net assets assigned to the reporting unit exceeds the fair value of the reporting unit, then the Company will recognize a loss equal to the excess, limited to the total amount of goodwill allocated to that reporting unit. Impairments, if any, are charged directly to earnings. In 2021, the Company performed a qualitative assessment and did not identify any indicators of impairment. No impairment charges have been incurred during 2021, 2020, or 2019. Intangible Assets Other Than Goodwill Tradenames acquired in certain business combinations were determined to have indefinite useful lives and are not amortized, but instead are tested for impairment on an annual basis and when facts and circumstances indicate that the carrying values of the assets may be impaired. If such review indicates an asset’s carrying value may not be recoverable, an impairment loss is recognized for the excess of the carrying value over the fair value of the asset. As part of separate business acquisitions, the Company’s customer relationships, technology and certain tradenames were identified as definite-lived intangible assets. The customer relationship intangible assets are being amortized over a ten to twenty-five year life based on the attrition rate of customers. The technology intangible assets are being amortized over a five to fourteen year life based on the lifecycle of previous technology. The tradenames are being amortized over a fifteen to twenty year life based on the estimated life of the tradename. Property, Plant and Equipment Property, plant and equipment acquired in various acquisitions have been recorded at fair value. All other property, plant and equipment is recorded at cost. Depreciation and amortization are provided for using the straight-line method over the estimated useful lives of the assets. Estimated useful lives for new property, plant and equipment additions are seven years to twenty-five years for buildings and improvements and three to ten years for machinery and equipment. Maintenance, repairs, and betterments which do not enhance the value of or increase the life of the assets are expensed as incurred. Debt Issuance Costs Debt issuance costs are being amortized using the effective interest method over the term of the related debt. As of December 31, 2021 and 2020 unamortized debt issuance costs were $ 13,264 and $ 16,684 , respectively, and are included as a reduction of debt. In connection with the Company's refinancing of its existing credit facility in 2021, a loss on the early extinguishment of debt of $ 13,650 was recognized for the write-off of unamortized debt issuance costs. Additionally, the Company paid $ 13,413 in original issue discount and issuance costs related to the new credit facility. Amortization expense for debt issuance costs was $ 3,182 , $ 3,092 , and $ 3,097 in 2021, 2020 and 2019, respectively, which is included in interest expense in the accompanying consolidated statements of comprehensive income (loss). Self-Insurance The Company is self-insured for employee medical and prescription drug benefits up to certain stop loss coverage amounts. The Company accrues an estimate for unpaid claims, as well as incurred but not reported claims, based upon the Company’s claim experience and expectations of future claim activity. The resulting liability and expense are reflected as a component of accrued expenses, cost of sales and selling, general and administrative expenses in the accompanying consolidated balance sheets and consolidated statements of comprehensive income (loss), respectively. Revenue Recognition The Company recognizes revenue with customers when control of the promised goods transfers to the customer. This generally occurs when the product is shipped to the customer. Revenue is recorded at the amount of consideration the Company expects to be entitled to in exchange for the delivered goods, which includes an estimate of variable consideration, expected returns, or refunds when applicable. The Company estimates variable consideration, such as sales incentives, by using the most likely amount approach, which considers the single most likely amount from a range of possible consideration amounts. Estimates of variable consideration result in an adjustment to the transaction price such that it is probable that a significant reversal of cumulative revenue would not occur in the future. Sales incentives and allowances are recognized as a reduction to revenue at the time of the related sale. Revenue is recorded net of sales tax. Shipping and handling fees billed to customers are included in net sales, while costs of shipping and handling are included in selling, general and administrative costs. For more information about the Company’s revenue from contracts with customers, refer to Note 9 Revenue. Customer Sales Incentives Sales incentives provided take the form of either sales discounts or rebates and are treated as a reduction of net sales. The Company also maintains a cooperative advertising program with its customers and provides sales incentives to the extent of the estimated value of advertising provided by the customer on behalf of the Company. The costs incurred under the cooperative advertising program are included as a reduction of net sales. Sales Returns Estimated sales returns and allowances are recorded as a charge against gross sales in the period in which the related sales are recognized, net of returns to stock. The Company allows customers to return products when certain Company-established criteria are met. The Company estimates sales returns based primarily upon actual historical returns, planned product discontinuances, and promotional sales. Returned products, which are recorded as inventories, are valued at the lower of cost or net realizable value. The physical condition and marketability of the returned products are the major factors considered in estimating realizable value. Income Taxes Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred 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 recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. The Company recognizes income tax positions only if those positions are “more likely than not” of being sustained upon examination by taxing authorities. Recognized income tax positions are measured at the largest amount that is greater than 50% likely of being realized. Changes in recognition or measurement are reflected in the period in which the change in judgment occ urs. The Company recognizes interest on liabilities for uncertain tax positions in interest expense and would recognize penalties, if any, in operating expenses in its consolidated income statements. The Company has no amounts accrued for such interest or penalties as of December 31, 2021 and 2020. Th e Company files income tax returns in the U.S. federal jurisdiction and various foreign and state jurisdictions. As of December 31, 2021 and 2020, the Company did no t have any unrecognized tax benefits. The statute of limitations remains open for U.S. federal income tax examinations for years ende d December 31, 2018 through December 31, 2020. U.S. state jurisdictions have statues of limitations generally ranging from three to eight years . The Company does no t expect the total amount of unrecognized tax benefits to sign ificantly change in the next 12 months. Impairment or Disposal of Long-Lived Assets The Company accounts for long-lived assets, including intangible assets subject to amortization, in accordance with the provisions that require long-lived assets, such as property and equipment, be reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to the sum of undiscounted net cash flows expected to be generated by the asset. If the carrying amount of an asset exceeds its estimated future cash flows, an impairment charge is recognized by the amount by which the carrying amount of the asset exceeds the fair value of the asset. Assets to be disposed of are reported at the lower of the carrying amount or fair value less costs to sell. Advertising Advertising production costs are expensed the first time the advertising takes place. Total advertising expenses were $ 6,299 , $ 4,379 , and $ 3,921 for the years ended December 31, 2021, 2020, and 2019, respectively. Advertising costs are classified as a component of selling, general and administrative costs in the accompanying consolidated statements of comprehensive income (loss). Research and Development Costs Research, development, pre-production and start-up costs related to both present and future products are expensed as incurred. Such costs amount to $ 28,280 , $ 23,483 , and $ 20,630 for the years ended December 31, 2021, 2020, and 2019, respectively. Other Comprehensive Income (Loss) Comprehensive loss encompasses all changes in stockholder’s equity and includes net income, change in the foreign currency translation adjustment and minimum pension liability. The Company’s accumulated other comprehensive loss shown on the consolidated balance sheets as of December 31, 2021 and 2020 consists of minimum pension loss of $ 302 and $ 690 , respectively, and foreign currency translation adjustments of $( 46 ) and $( 16 ) , respectively. Foreign Currencies The functional currency of the Company’s Italian subsidiary is the Euro. Assets and liabilities of foreign operations are translated using period end exchange rates. Revenue and expenses are translated using average exchange rates during each period reported. Translation gains are reported in accumulated other comprehensive loss as a component of shareholders equity and were $ 30 and $ 16 as of December 31, 2021 and 2020, respectively. The Company recognizes foreign currency transaction gains (losses) on certain assets and liabilities. These transaction (gains) losses are reported in other expense in the consolidated statements of comprehensive income (loss) and were $ 44 , $( 284 ) , and $( 27 ) for the years ended December 31, 2021, 2020 and 2019, respectively. Earnings per Share Earnings per share is computed by dividing net income or loss available to common stockholders by the weighted average number of common shares outstanding for the period. Diluted earnings per share is computed by giving effect to all potential dilutive common stock equivalents outstanding for the period. The dilutive effect of these potential common shares is reflected in diluted earnings per share by application of the treasury stock method. Warrants The Company reviews the terms of warrants to purchase its common stock to determine whether warrants should be classified as liabilities or stockholders' equity in its consolidated balance sheet. In order for a warrant to be classified in stockholders' equity, the warrant must be (a) indexed to the Company's equity and (b) meet the conditions for equity classification in Accounting Standards Codification ("ASC") Subtopic 815-40, Derivatives and Hedging-Contracts in an Entity's Own Equity. If a warrant does not meet the conditions for equity classification, it is carried in the consolidated balance sheet as a warrant liability measured at fair value, with subsequent changes in the fair value of the warrant recorded in the consolidated statements of comprehensive income as a non-operating expense. If a warrant meets both conditions for equity classification, the warrant is initially recorded in additional paid-in capital on the consolidated balance sheet, and the amount initially recorded is not subsequently re-measured at fair value. Equity-Based Compensation The Company accounts for equity-based awards granted to employees and nonemployees under the fair value method prescribed by ASC Subtopic 718-10, Stock Compensation. Equity-based compensation cost is measured based on the estimated grant date fair value of the award and is recognized as expense over the requisite service period (generally the vesting period). The Company accounts for forfeitures as they occur. The fair value of stock options is estimated using the Black Scholes option-pricing model. Restricted stock units are valued at the stock price on the grant date. The fair value of profit interest units ("PIUs") granted by Holley Parent Holdings, LLC (the “Holley Stockholder” or “Parent”) is estimated based on the Company’s estimated equity value for each unit class at the time of granting using the Black-Scholes option-pricing model, discounted to reflect market considerations for illiquidity. Fair Value Measurements Fair value is defined as the price that would be received for sale of an asset or paid for transfer of a liability, in an orderly transaction between market participants at the measurement date. In determining fair value, the Company utilizes valuation techniques that maximize the use of observable inputs and minimizes the use of unobservable inputs to the extent possible. The inputs used to measure fair value are prioritized based on a three-level hierarchy, which are defined as follows: Level 1 – Quoted prices (unadjusted) for identical assets or liabilities in active markets that the entity has the ability to access as of the measurement date. Level 2 – Significant other observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data. Level 3 – Significant unobservable inputs that reflect a company’s own assumptions about the assumptions that market participants would use in pricing an asset or liability. Derivative Financial Instruments The Company evaluates its financial instruments to determine if such instruments are derivatives or contain features that qualify as embedded derivatives in accordance with ASC Topic 815, “Derivatives and Hedging”. For derivative financial instruments that are accounted for as liabilities, the derivative instrument is initially recorded at its fair value on the grant date and is then re-valued at each reporting date, with changes in the fair value reported in the statements of operations. Derivative liabilities are classified on the balance sheet as current or non-current based on whether or not net-cash settlement or conversion of the instrument could be required within 12 months of the balance sheet date. Recent Accounting Pronouncements Accounting Standards Recently Adopted The FASB issued 2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. The amendments in ASU 2016-13 will provide more decision-useful information about the expected credit losses on financial instruments and other commitments to extend credit held by a reporting entity at each reporting date. The ASU is effective for annual reporting periods beginning after December 15, 2022. The Company early adopted the standard in 2020. There was no material impact of adopting this guidance on its financial statements. Accounting Standards Not Yet Adopted In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) which requires lessees to recognize right-of-use assets, representing their right to use the underlying asset for the lease term, and lease liabilities on the balance sheet for all leases with terms greater than 12 months. The Company has substantially completed its preparation for the adoption of this new accounting standard. This included assessing the completeness of our lease arrangements, evaluating practical expedients and accounting policy elections, and executing changes to our business process. ASU 2016-02 is effective for the Company beginning January 1, 2022. The standard requires the use of a modified retrospective transition approach, which includes a number of optional practical expedients that entities may elect to apply. The Company expects to elect certain practical expedients, including the package of practical expedients to not reassess prior conclusions related to contracts containing leases, lease classification and initial direct costs, and is evaluating the other practical expedients available under the guidance. The Company also plans to elect the optional transition method that will give companies the option to use the effective date as the date of initial application on transition, and as a result, we will not adjust our comparative period financial information or make the new required lease disclosures for periods before the effective date. The Company anticipates the adoption of this new standard will result in an increase of approximately 3 percent of total assets and approximately 4 percent of total liabilities on our consolidated balance sheet. We do not expect the new standard to have a material impact on the Company's consolidated statement of income or consolidated statement of cash flows. While we are substantially complete with the process of quantifying the impacts that will result from applying the new guidance, our assessment will be finalized during the first quarter of 2022. In August 2018, the FASB issued ASU 2018-14, Compensation – Retirements Benefits – Defined Benefit Plans – General (Subtopic 715-20). The ASU is effective for the Company for annual reporting periods beginning after December 15, 2021 with early adoption permitted. This guidance should be applied on a retrospective basis to all periods presented. The ASU will update disclosure requirements for employers that sponsor defined benefit pension or other post retirement plans. The Company is in the process of terminating its defined benefit pension plan and does not expect this guidance to have a significant impact on its financial statements or related disclosures. In December 2019, the FASB issued ASU 2019-12, Simplifying the Accounting for Income Taxes (Topic 740) which is intended to simplify various aspects related to accounting for income taxes. This ASU is effective for the Company for annual reporting periods beginning after December 15, 2021 and interim periods therein, with early adoption permitted. The ASU removes certain exceptions to the general principles in Topic 740 and also clarifies and amends existing guidance to improve consistent application. The Company does not expect the adoption of this ASU to have a material impact on its financial statements. In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848). The ASU provides optional expedients and exceptions for applying GAAP to contracts, hedging relationships, and other transactions affected by reference rate reform if certain criteria are met. Adoption of the provisions of ASU 2020-04 are optional and are effective from March 12, 2020 through December 31, 2022. As of December 31, 2021, the Company did not adopt any expedients or exceptions under ASU 2020-04. The Company will continue to evaluate the impact of ASU 2020-04 and whether it will apply the optional expedients and exceptions. In August 2020, the FASB issued ASU 2020-06, Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity (Subtopic 470-20). The ASU is effective for the Company for annual reporting periods beginning after December 15, 2023 and interim periods therein, with early adoption permitted as of the beginning of the Company's annual fiscal year. The ASU includes amendments to the guidance on convertible instruments and the derivative scope exception for contracts in an entity’s own equity and simplifies the accounting for convertible instruments which include beneficial conversion features or cash conversion features by removing certain separation models in Subtopic 470-20. Additionally, the ASU requires entities to use the “if-converted” method when calculating diluted earnings per share for convertible instruments. When adopted, the ASU will result in changes in the fair value of its public warrants being recognized through equity rather than through the statement o f income. The Company plans to early adopt the standard as of January 1, 2022.

Business Combinations [Abstract]
BUSINESS COMBINATION AND ACQUISITIONS	2. BUSINESS COMBINATION AND ACQUISITIONS BUSINESS COMBINATION On July 16, 2021, Holley consummated the Business Combination pursuant to the terms of the Merger Agreement, whereby (i) Merger Sub I, a direct wholly owned subsidiary of Empower, merged with and into Holley Intermediate, with Holley Intermediate surviving such merger as a wholly owned subsidiary of Holley (“Merger I”) and (ii) Merger Sub II, a direct wholly owned subsidiary of Empower, merged with and into Holley Intermediate, with Merger Sub II surviving such merger as a wholly owned subsidiary of Holley (“Merger II”). Pursuant to the Merger Agreement, at the Closing, all outstanding shares of Holley Intermediate common stock as of immediately prior to the effective time of Merger I were cancelled and the Holley Stockholder, the sole stockholder of Holley Intermediate, received $ 264,718 in cash and 67,673,884 shares of common stock (at a deemed value of $ 10.00 per share). The Company’s common stock is listed on the NYSE under the symbol “HLLY.” In connection with the Business Combination, a number of subscribers purchased from the Company an aggregate of 24,000,000 shares of common stock (the “PIPE”), for a purchase price of $ 10.00 per share, or $ 240,000 in the aggregate. Per the Merger Agreement, $ 100,000 of the PIPE proceeds were used to partially pay off Holley’s debt. Pursuant to the Amended and Restated Forward Purchase Agreement (“A&R FPA”), at the Closing, 5,000,000 shares of the Company’s common stock and 1,666,667 warrants were issued to certain investors for an aggregate purchase price of $ 50,000 . Pursuant to the A&R FPA, each warrant entitles the holder to purchase one share of the Company’s common stock at a price of $ 11.50 per share (the ”Public Warrants”), subject to certain conditions. The Company also assumed 8,333,310 Public Warrants and 4,666,667 private placement warrants (the “Private Warrants”, and together with the Public Warrants, the “Warrants”) upon the Business Combination, all of which were issued in connection with Empower’s initial public offering. Each Warrant represents the right to purchase one share of the Company’s common stock at a price of $ 11.50 per share, subject to certain conditions. The Warrants are exercisable commencing on October 9, 2021 (the one-year anniversary of Empower’s initial public offering) and expire on July 16, 2026 ( five years after the Closing Date). The Public Warrants are listed on the NYSE under the symbol “HLLY WS.” Additionally, Empower Sponsor Holdings LLC (the "Sponsor") may be entitled to receive up to 2,187,500 shares of the Company’s common stock vesting in two equal tranches upon achieving certain market share price milestones as outlined in the Merger Agreement during the earn-out period (“the “Earn-Out Shares”). The Earn-Out Shares will be forfeited if the applicable conditions are not satisfied before July 16, 2028 (seven years after the Closing Date). The earnout is classified as a liability in the consolidated balance sheet and is re-measured at fair value with changes in the post-Business Combination fair value recognized in the Company’s consolidated statement of comprehensive income (loss) as non-operating expense. The Business Combination was accounted for as a reverse recapitalization in accordance with U.S. GAAP. This determination was primarily based on the Holley Stockholder having a relative majority of the voting power of the Company, the operations of Holley prior to the acquisition comprising the only ongoing operations of the Company, and senior management of Holley comprising the majority of the senior management of the Company. Under this method of accounting, Empower was treated as the acquired company for financial reporting. Accordingly, the Business Combination was accounted for as the equivalent of Holley issuing stock for the net assets of Empower, accompanied by a recapitalization. The net assets of Empower are stated at historical cost, with no goodwill or other intangible assets recorded. Reported amounts from operations included herein prior to the Business Combination are those of Holley Intermediate. The shares and corresponding capital amounts and earnings per share, prior to the Business Combination, have been retroactively restated based on shares received by the Holley Stockholder. The following table reconciles the elements of the Business Combination to the consolidated statements of cash flows for the year ended December 31, 2021: Recapitalization Cash - Empower's trust and cash (net of redemptions of $ 99,353 and 44,314 ) $ 107,017 Cash - Forward Purchase Agreement 50,000 Cash - PIPE Financing 240,000 Net cash provided by Business Combination and PIPE Financing 397,017 Less: cash consideration paid to Holley Stockholder ( 264,718 ) Net contributions from Business Combination and PIPE Financing $ 132,299 ACQUISITIONS During the three years ended December 31, 2021, the Company completed 12 acquisitions. These acquisitions are expected to enhance the Company's portfolio of products and services in the automotive aftermarket and automotive safety solutions market. The company accounts for acquisitions using the acquisition method, and accordingly, the purchase price has been allocated based upon the fair value of the assets acquired and liabilities assumed. The valuation of the assets acquired and liabilities assumed is subject to revision. If additional information becomes available, the Company may further revise the purchase price allocation as soon as practical, but no later than one year from the acquisition date; however, material changes are not expected. Goodwill generated by the acquisitions is primarily attributable to the strong market position of the entities acquired. Purchase price consideration for all acquisitions was paid primarily in cash. All acquisitions were for 100 percent of the acquired business and are reported in the Consolidated Statements of Cash Flows, net of acquired cash and cash equivalents. Acquisition-related costs, including advisory, legal, accounting, valuation and other costs, are typically expensed in the periods in which the costs are incurred and are recorded in acquisition and restructuring costs. The results of operations of acquired businesses are included in the consolidated financial statements from the acquisition date. In 2021, the Company acquired substantially all the assets of Finspeed, LLC (“Finspeed”), Classic Instruments LLC (“Classic Instruments”), ADS Precision Machining, Inc., doing business as Arizona Desert Shocks (“ADS”), Rocket Performance Machine, Inc., doing business as Rocket Racing Wheels (“Rocket”), and Speartech Fuel Injections Systems, Inc. (“Speartech”). These five acquisitions were individually immaterial business combinations that are material in the aggregate. Cash paid for the five immaterial acquisitions, net of cash acquired, was $ 19,685 , and was funded with borrowings from the Company's credit facility and cash on hand. The acquisitions resulted in both amortizable and non-amortizable intangibles and goodwill totaling $ 13,145 . The goodwill and intangibles generated as a result of these acquisitions are deductible for income tax purposes. Pro forma results of operations and the results of operations since the acquisition dates for these immaterial acquisitions have not been separately disclosed because the effects were not significant compared to the consolidated financial statements, individually or in the aggregate. The determination of the final purchase price allocation to specific assets acquired and liabilities assumed may change in future periods as the fair value estimates of inventory and intangibles are completed. The allocation of the purchase price to the assets acquired and liabilities assumed was based on estimates of the fair value of the net assets as follows: Cash $ 122 Accounts receivable 618 Inventory 3,975 Property, plant and equipment 2,274 Other assets 23 Tradenames 2,608 Customer relationships 2,450 Goodwill 8,087 Accounts payable ( 343 ) Accrued liabilities ( 129 ) $ 19,685 The fair value of the acquired customer relationship intangible assets were estimated using the excess earnings approach. The customer relationship intangible assets are being amortized based on the attrition rate of customers which have an estimated weighted average life of 18 years. The fair value of the acquired tradenames intangible asset was estimated using the relief from royalty method, a form of the income approach. The tradenames were determined to have an indefinite life. The remaining seven acquisitions completed during the three years ended December 31, 2021 are described below. Baer, Inc.

The allocation of the purchase price to the assets acquired and liabilities assumed was based on estimates of the fair value of the net assets as follows: Cash $ 218 Accounts receivable 94 Inventory 231 Property, plant and equipment 7 Other assets 60 Tradename 510 Technology intangible 5,695 Goodwill 2,072 Accounts payable ( 64 ) Accrued liabilities ( 4 ) Deferred tax liability ( 1,580 ) $ 7,239 The fair value of the acquired technology intangible asset was estimated using the relief from royalty method, a form of the income approach. The technology intangible asset is being amortized over the estimated lifecycle of the technology which was determined to be 14 years. The fair value of the acquired tradename intangible asset was estimated using the relief from royalty method, a form of the income approach. The tradename was determined to have an indefinite life. The contractual value of the accounts receivable acquired was $ 94 . The following table provides the unaudited consolidated pro forma results for the periods presented as if Baer, Brothers, AEM, Drake, Simpson, and Detroit Speed had been acquired as of January 1, 2020. For the years ended December 31, 2021 December 31, 2020 Pro forma net sales $ 727,369 $ 631,560 Pro forma net income (loss) ( 8,464 ) 31,435 The following table presents the supplemental and unaudited pro forma results as if Range, Drake, Simpson and Detroit Speed had been acquired as of January 1, 2019: For the years ended December 31, 2020 December 31, 2019 Pro forma net sales $ 584,270 $ 461,418 Pro forma net income (loss) 37,304 ( 8,799 ) The pro forma results include the effects of the amortization of purchased intangible assets and acquired inventory step-up.

Debt Disclosure [Abstract]
Debt	6. DEBT Debt of the Company consisted of the following: December 31, 2021 2020 First lien term loan due November 17, 2028 $ 630,000 $ — Revolver 25,000 — First lien note — 541,969 Second lien note — 145,000 Other 3,812 4,701 Less unamortized debt issuance costs ( 13,264 ) ( 16,684 ) 645,548 674,986 Less current portion of long-term debt ( 7,875 ) ( 5,528 ) $ 637,673 $ 669,458 On November 18, 2021, the Company entered into a new credit facility with a syndicate of lenders and Wells Fargo Bank, N.A., as administrative agent for the lenders, letter of credit issuer and swing line lender (the "Credit Agreement"). The financing consists of a seven-year $ 600,000 first lien term loan, a five-year $ 125,000 revolving credit facility, and a $ 100,000 delayed draw term loan. As of December 31, 2021, the Company had drawn $ 30,000 under the delayed draw term loan. The delayed draw term loan is available for six months and is subject to the satisfaction of certain conditions precedent, including, but not limited to, the consent of the lenders providing the delayed draw term loan. In addition, the credit facility includes a letter of credit facility in the amount of $ 10,000 , pursuant to which letters of credit may be issued as long as revolving loans may be advanced and subject to availability under the revolving credit fac ility. The Company had $ 1,200 in outstanding letters of credit at December 31, 2021. Proceeds from the new credit facility were used to repay in full the obligations outstanding under both the Company’s existing first lien and second lien notes and to p ay $ 13,413 in or iginal issue discount and issuance costs related to the refinancing. The proceeds of any delayed draw loans made after closing may be used by the Company to finance acquisitions. The first lien term loan is to be repaid in quarterly payments of $ 1,500 from December 31, 2021 to September 30, 2028 with the balance due upon maturity on November 17, 2028 . Beginning with the fiscal year ending on December 31, 2022, at the end of each fiscal year, the Company is required to make a payment based on its available free cash flow (as defined in the Credit Agreement). Any such payments offset future mandatory quarterly payments. Amounts outstanding under the new credit facility will accrue interest at a rate equal to either LIBOR or base rate, at the Company's election, plus a specified margin. In the case of revolving credit loans and letter of credit fees, the specified margin is based on the Company's Total Leverage Ratio, as defined in the Credit Agreement. Commitment fees payable under the revolving credit facility are based on the Company's Total Leverage Ratio. At December 31, 2021, the weighted average interest rate on the Company's borrowings under the credit facility was 4.5 %. Obligations under the Credit Agreement are secured by substantially all of the Company’s assets. The Credit Agreement includes representations and warranties, and affirmative and negative covenants customary for financings of this type, including, but not limited to, limitations on restricted payments, additional borrowings, additional investments, and asset sales. It also requires that Holley maintain on the last day of each quarter, a Total Leverage Ratio not to exceed a maximum amount. At December 31, 2021, the Company was in compliance with all financial covenants. Some of the lenders and their affiliates have various relationships with the Company in the ordinary course of business involving the provision of financial services, including cash management, commercial banking, investment banking or other services. In 2021, as a result of prepayments of the Company’s existing first lien and second lien notes, losses of $ 13,650 w ere recognized on the early extinguishment of debt due to the write-off of unamortized debt issuance costs. The first lien note totaled $ 600,000 , comprised of two parts: a revolving component with maximum borrowings of $ 50,000 , and a $ 550,000 term loan. The proceeds of the new first lien term loan were used to repay the $ 537,820 outstanding principal balance of the existing first lien note, which resulted in a loss of $ 11,638 from the write-off of unamortized debt issuance costs. The interest rate for the first lien note LIBOR rate loans was 5.2 % at December 31, 2020. There were no prime rate loans as of December 31, 2020. The Company had $ 1,200 in outstanding letters of credit under the first lien note at December 31, 2020. The second lien note totaled $ 145,000 . On July 16, 2021, the Company used a portion of the net proceeds from the Business Combination to repay $ 100,000 of the outstanding principal of the second lien note, which resulted in a loss of $ 1,425 from the write-off of unamortized debt issuance costs. The remaining $ 45,000 outstanding balance was repaid with proceeds from the new first lien term loan, which resulted in a loss of $ 587 from the write-off of unamortized debt issuance costs. The interest rate for the second lien note LIBOR rate loan was 8.7 % at December 31, 2020. Sentinel Capital Partners Junior Fund I, a related party, held $ 20,000 of the second lien note at December 31, 2020. Future maturities of long-term debt and amortization of debt issuance costs as of December 31, 2021 are as follows: Debt Debt Issuance Costs 2022 $ 8,774 $ 1,769 2023 7,207 1,817 2024 7,215 1,708 2025 7,391 1,912 2026 31,300 1,964 Thereafter 596,925 4,094 $ 658,812 $ 13,264

Warrant Liability [Abstract]
COMMON STOCK WARRANTS	7. COMMON STOCK WARRANTS Upon the Closing, there were 14,666,644 Warrants, consisting of 9,999,977 Public Warrants and 4,666,667 Private Warrants, outstanding to purchase shares of the Company's common stock that were issued by Empower prior to the Business Combination. Each warrant entitles the registered holder to purchase one share of the Company's common stock at a price of $ 11.50 per share, subject to adjustments, commencing on October 9, 2021 (the one-year anniversary of Empower’s initial public offering), provided that the Company has an effective registration statement under the Securities Act covering the shares of common stock issuable upon exercise of the warrants and a current prospectus relating to them is available and such shares are registered, qualified or exempt from registration under the securities laws of the state of residence of the holder. The Warrants may be exercised only for a whole number of shares of the Company’s common stock. The Warrants expire on July 16, 2026 , the date that is five years after the Closing date, or earlier upon redemption or liquidation. Additionally, the Private Warrants will be non-redeemable and are exercisable on a cashless basis so long as they are held by the Sponsor or any of its permitted transferees. If the Private Warrants are held by someone other than the Sponsor or its permitted transferees, the Private Warrants will be redeemable by the Company and exercisable by such holders on the same basis as the Public Warrants. The Company may redeem the Public Warrants at a price of $ 0.01 per warrant upon 30 days' notice if the closing price of the Company’s common stock equals or exceeds $ 18.00 per share, subject to adjustments, on the trading day prior to the date on which notice of redemption is given, provided there is an effective registration statement and current prospectus in effect with respect to the ordinary shares underlying such Warrants throughout the 30-day redemption period. If the foregoing conditions are satisfied and the Company issues a notice of redemption of the Warrants, the Warrant holder is entitled to exercise his, her or its Warrant prior to the scheduled redemption date. Any such exercise requires the Warrant holder to pay the exercise price for each Warrant being exercised. Further, the Company may redeem the Public Warrants at a price of $ 0.10 per warrant upon 30 days' notice if the closing price of the Company’s common stock equals or exceeds $ 10.00 per share, subject to adjustments, on the trading day prior to the date on which notice of redemption is given. Beginning on the date the notice of redemption is given until the Warrants are redeemed or exercised, holders may elect to exercise their Warrants on a cashless basis and receive that number of shares of the Company’s common stock as determined by reference to a table in the warrant agreement. If a registration statement is not effective within 60 days following the Closing, warrant holders may, until such time as there is an effective registration statement and during any period when the Company has failed to maintain an effective registration statement, exercise warrants on a cashless basis in accordance with Section 3(a)(9) of the Securities Act or another exemption, but the Company will use its commercially reasonable best efforts to register or qualify the shares under applicable blue sky laws to the extent an exemption is not available. The Company’s Warrants were accounted for as liabilities in accordance with ASC 815-40 and are presented as warrant liability on the balance sheet. The warrant liability was measured at fair value at inception and on a recurring basis, with changes in fair value recognized as non-operating expense. As of December 31, 2021, a warrant liability with a fair value of $ 61,293 was reflected as a long-term liability in the consolidated balance sheet, and a $ 32,580 increase in the fair value of the warrant liability was reflected as change in fair value of warrant liability in the consolidated statements of comprehensive income for year ended December 31, 2021.

FAIR VALUE MEASUREMENTS

Fair Value Disclosures [Abstract]
FAIR VALUE MEASUREMENTS	8. FAIR VALUE MEASUREMENTS The Company’s financial liabilities subject to fair value measurement on a recurring basis and the level of inputs used for such measurements were as follows: Fair Value Measured as of December 31, 2021 Level 1 Level 2 Level 3 Total Liabilities included in: Warrant liability (Public) $ 39,500 $ — $ — $ 39,500 Warrant liability (Private) — — 21,793 21,793 Earn-out liability — — 26,596 26,596 Total fair value $ 39,500 $ — $ 48,389 $ 87,889 As of December 31, 2021, the Company's derivative liabilities for its private and public warrants, the earn-out liability (see Note 2, “Business Combination and Acquisitions,” for more details), and the acquisition contingent consideration payable are measured at fair value on a recurring basis. The fair value for the private warrants, earn-out liability, and acquisition contingent consideration payable are determined based on significant inputs not observable in the market (Level 3). The valuation of the Level 3 liabilities uses assumptions and estimates the Company believes would be made by a market participant in making the same valuation. The Company assesses these assumptions and estimates on an on-going basis as additional data impacting the assumptions and estimates are obtained. The Company uses a Monte Carlo simulation model to estimate the fair value of its private warrants and earn-out liability. The fair value of the public warrants is determined using publicly traded prices (Level 1). Changes in the fair value of the derivative liabilities related to warrants and the earn-out liability are recognized as non-operating expense in the consolidated statements of comprehensive income (loss). Changes in the fair value of acquisition contingent consideration payable are recognized as acquisition and restructuring costs in the consolidated statements of comprehensive income (loss). As of December 31, 2020, the Company's financial liabilities subject to fair value measurement on a recurring basis consisted of acquisition contingent consideration payables of $ 9,200 , for which the fair value was determined based on significant inputs not observable in the market (Level 3). The fair value of private warrants was estimated as of December 31, 2021 using the Monte Carlo simulation model with the following assumptions: Valuation date price $ 12.99 Strike price $ 11.50 Remaining life 4.54 years Expected dividend $ — Risk-free interest rate 1.19 % Price threshold $ 18.00 The fair value of the earn-out liability was estimated as of December 31, 2021 using the Monte Carlo simulation model with the following assumptions: Valuation date price $ 12.99 Expected term 6.54 years Expected volatility 40.59 % Risk-free interest rate 1.40 % Price hurdle 1 $ 13.00 Price hurdle 2 $ 15.00 As of December 31, 2021 and 2020, the Company had accounts receivable, accounts payable and accrued expenses for which the carrying value approximates fair value due to the short-term nature of these instruments. The carrying value of the Company’s long-term debt approximates fair value as the rates used approximate the market rates currently available to the Company. Fair value measurements used in the impairment reviews of goodwill and intangible assets are Level 3 measurements. The reconciliation of changes in Level 3 during the year ended December 31, 2021 is as follows: For the year ended December 31, 2021 Private Warrants Acquisition Contingent Consideration Earn-Out Liability Total Balance on December 31, 2020 $ — $ 9,200 $ — $ 9,200 Cash paid for contingent consideration — ( 26,573 ) — ( 26,573 ) Liabilities assumed in recapitalization 9,613 — 17,722 27,335 Losses included in earnings 12,180 17,373 8,874 38,427 Balance on December 31, 2021 $ 21,793 $ — $ 26,596 $ 48,389

REVENUE

Revenue from Contract with Customer [Abstract]
REVENUE	9. REVENUE The principal activity from which the Company generates its revenue is the manufacturing and distribution of after-market automotive parts for its customers, comprised of resellers and end users. The Company recognizes revenue at a point in time, rather than over time, as the performance obligation is satisfied when customer obtains control of the product upon title transfer and not as the product is manufactured or developed. The amount of revenue recognized is based on the purchase order price and adjusted for revenue allocated to variable consideration (i.e., estimated rebates, co-op advertising, etc.). The Company collects sales tax and other taxes concurrent with revenue-producing activities which are excluded from revenue. Shipping and handling costs incurred after control of the product is transferred to our customers are treated as fulfillment costs and not a separate performance obligation. The Company allows customers to return products when certain Company-established criteria are met. These sales returns are recorded as a charge against gross sales in the period in which the related sales are recognized, net of returns to stock. Returned products, which are recorded as inventories, are valued at the lower of cost or net realizable value. The physical condition and marketability of the returned products are the major factors considered in estimating realizable value. The Company also estimates expected sales returns and records the necessary adjustment as a charge against gross sales. The Company’s payment terms with customers are customary and vary by customer and geography but typically range from 30 to 365 days. The Company elected the practical expedient to disregard the possible existence of a significant financing component related to payment on contracts, as the Company expects that customers will pay for the products within one year. The Company has evaluated the terms of our arrangements and determined that they do not contain significant financing components. Additionally, as all contracts with customers have an expected duration of one year or less, the Company has elected the practical expedient to exclude disclosure of information regarding the aggregate amount and future timing of performance obligations that are unsatisfied or partially satisfied as of the end of the reporting period. The Company provides limited warranties on most of its products against certain manufacturing and other defects. Provisions for estimated expenses related to product warranty are made at the time products are sold. Refer to Note 17 for more information. The following table summarizes total revenue by product category: For the years ended December 31, 2021 December 31, 2020 December 31, 2019 Electronic systems $ 324,522 $ 266,742 $ 199,295 Mechanical systems 161,836 119,784 92,498 Exhaust 76,971 71,915 51,802 Accessories 63,427 38,543 25,068 Safety 66,091 7,195 — Total sales $ 692,847 $ 504,179 $ 368,663 The following table summarizes total revenue based on geographic location from which the product is shipped: For the years ended December 31, 2021 December 31, 2020 December 31, 2019 United States $ 674,491 $ 502,661 $ 368,663 Italy 18,356 1,518 — Total sales $ 692,847 $ 504,179 $ 368,663

As of December 31, 2021, the Company's federal and state net operating loss carryforwards for income tax purposes were immaterial. A majority of the U.S. net operating loss carryforwards have no expiration date. The remaining state net operating loss carryforwards expire at various dates through 2035. The entire amount of federal net operating loss carryforward of $ 865 and a significant portion of state net operating loss carryforward of $ 566 relate to acquisitions, and, as a result, are limited in the amount that can be recognized in any one year. Uncertain Tax Positions Under the accounting rules for income taxes, the Company is not permitted to recognize the tax benefit attributable to a tax position unless such position is more likely than not to be sustained upon examination by taxing authorities, including resolution of any related appeals and litigation processes, based solely on the technical merits of the position. The Company did not have any uncertain tax positions for the year ended December 31, 2021. The Company recognizes interest on liabilities for uncertain tax positions in interest expense and would recognize penalties, if any, in operating expenses in its consolidated statements of comprehensive income (loss). In 2021 and 2020, the Company has no t recognized any amount of interest and penalties for uncertain tax positions in its consolidated statements of comprehensive income (loss). The Company files federal, state, and non-U.S. tax returns in various foreign jurisdictions. For state and non-U.S. tax returns, the Company is generally no longer subject to tax examinations for years prior to 2012. For federal tax returns, the Company is no longer subject to tax examination for years prior to 2018. The federal tax returns for 2018 through 2020 remain open for examinations. State income tax returns remain open for examination in various states for tax years 2012 through 2020. The Company's tax policy is to comply with the laws, regulations, and filing requirements of all jurisdictions in which it conducts business. Management regularly engages in discussions and negotiations with tax authorities regarding tax matters in various jurisdictions. Although the timing of the resolutions and/or closures of audits is highly uncertain, it is reasonably possible, that certain U.S. federal and non-U.S. tax audits may be concluded within the next 12 months, which could significantly increase or decrease the balance of our gross unrecognized tax benefits. However, the estimated impact of income tax expense and net income is not expected to be significant.

Retirement Benefits [Abstract]
BENEFIT PLANS	12. BENEFIT PLANS The Company has a defined benefit pension plan (the “Plan”) for its employees. The Projected Unit Credit Actuarial Cost Method is used to determine the normal cost of the Plan and estimated pension benefit obligation. During 2002, the Plan was amended to curtail accrual of future benefits under the Plan. The pension plan assets are managed to maximize total return over the long term while providing sufficient liquidity and current return to satisfy the cash flow requirements of the plan. The plan’s day-to-day investment decisions are managed by our outside investment manager; however, overall investment strategies are discussed with our employee benefits committee. Our investment strategy is to weight our portfolio towards large-cap, high-quality, dividend-growing equities that we have historically favored. As our plan matures and interest rates normalize, we expect a greater allocation to fixed-income securities to better align asset and liability market risks. Our fixed-maturity bond portfolio is investment grade. The plan does not engage in derivative transactions. On January 28, 2022, the Company approved the termination of our defined benefit pension plan, effective March 31, 2022. The distribution of the Plan assets pursuant to the termination will not be made until the plan termination satisfies all regulatory requirements, which is expected to be completed by the fourth quarter of 2022. Plan participants will receive their full accrued benefits from plan assets by electing either lump sum distributions or annuity contracts with a qualifying third-party annuity provider. The resulting settlement effect of the Plan termination will be determined based on prevailing market conditions, the lump sum offer participation rate of eligible participants, the actual lump sum distributions, and annuity purchase rates at the date of distribution. As a result, we are currently unable to reasonably estimate either the timing or the final amount of such settlement charges. Based on the valuation performed as of December 31, 2021, the Plan has an underfunded status of $ 862 . The following table shows the changes in the benefit obligation and plan assets and the plan’s funded status. December 31, 2021 2020 Change in Projected Benefit Obligation: Benefit obligation, January 1 $ 6,551 $ 5,993 Service cost 143 159 Interest cost 152 190 Benefits paid ( 349 ) ( 339 ) Expenses paid ( 135 ) ( 142 ) Actuarial (gain) loss ( 258 ) 690 Benefit obligation, December 31 $ 6,104 $ 6,551 Change in Plan Assets: Fair value of plan assets, January 1 $ 4,756 $ 4,089 Actual return on plan assets 499 559 Employer contributions 471 589 Benefits paid from plan assets ( 349 ) ( 339 ) Expenses paid ( 135 ) ( 142 ) Fair value of plan net assets, December 31 $ 5,242 $ 4,756 Underfunded status at end of period $ ( 862 ) $ ( 1,795 ) Amounts recognized in the consolidated balance sheet: Current liabilities $ — $ — Non-current liabilities ( 862 ) ( 1,795 ) Net amount recorded $ ( 862 ) $ ( 1,795 ) The accumulated benefit obligation for the Plan was $ 6,104 and $ 6,551 at December 31, 2021 and 2020. The Company made contributions of $ 471 , $ 589 and $ 285 in 2021, 2020 and 2019, respectively. There were no participant contributions in 2021, 2020 or 2019. Unrecognized actuarial losses are recognized as a component of accumulated other comprehensive income. The following table shows the balances reflected in accumulated other comprehensive income on a pre-tax basis for the periods presented: December 31, 2021 2020 Amounts recognized in accumulated other comprehensive loss (pre-tax): Net actuarial loss $ 283 $ 822 The pre-tax amounts recognized in other comprehensive income were as follows: For the years ended December 31, 2021 December 31, 2020 Actuarial (gain) loss arising during measurement period $ ( 513 ) $ 386 Amortization of actuarial loss ( 25 ) — Total recognized in other comprehensive (income) loss $ ( 538 ) $ 386 The following summarizes the components of net periodic benefit cost for the defined benefit pension plan: For the years ended December 31, 2021 December 31, 2020 December 31, 2019 Components of expense: Service cost $ 143 $ 159 $ 142 Interest cost 152 190 231 Expected return on plan assets ( 240 ) ( 255 ) ( 232 ) Amortization of net loss 25 — — Net periodic benefit cost $ 80 $ 94 $ 141 Weighted-average assumptions used to determine net cost: December 31, 2021 2020 Discount rate 2.38 % 3.25 % Expected return on plan assets 6.35 % 6.35 % The Company uses a measurement date of December 31 for its defined benefit pension plan. Weighted-average assumptions used to determine the benefit obligation: December 31, 2021 2020 Discount rate 2.78 % 2.38 % In order to develop the expected long-term rate of return on assets assumption, the Company considered the historical returns and the future expectations for returns for each asset class, as well as the target asset allocation of the pension portfolio. The fair value of the Plan assets at December 31, 2021 and 2020, by asset category, are as follows: For the years ended December 31, 2021 December 31, 2020 Common stock $ 789 $ 1,562 Mutual funds 2,171 2,202 Corporate / government bonds 2,354 982 Cash and cash equivalents 20 10 Total $ 5,334 $ 4,756 Following is a description of the valuation methodologies used for assets measured at fair value on a recurring basis as well as the general classification of such assets pursuant to the valuation hierarchy. Common Stock : The fair value of common stock investments is determined by obtaining quoted prices on nationally recognized securities exchanges (Level 1 inputs). Mutual Funds : The fair value of mutual fund investments is determined by obtaining quoted prices on nationally recognized securities exchanges (Level 1 inputs). Corporate/government bonds : The fair value of corporate/government bonds is based upon recent bid prices or the average of the recent bid and ask prices when available (Level 2 inputs) and if not available, they are valued through matrix pricing models developed by sources considered by management to be reliable. Matrix pricing, which is a mathematical technique commonly used to price debt securities that are not actively traded, values debt securities without relying exclusively on quoted prices for the specific securities but rather by relying on the securities’ relationship to other benchmark quoted securities (Level 2 inputs). The fair value of Holley’s pension plan assets at December 31, 2021 and 2020, by asset category using the Fair Value measurement hierarchy is shown in the table below. See Note 1, “Description of the Business, Basis of Presentation, and Summary of Significant Accounting Policies,” for more details about fair value measurements. December 31, 2021 Fair Value Level 1 Level 2 Level 3 Common stock $ 789 $ 789 $ — $ — Mutual funds 2,171 2,171 — — Corporate / government bonds 2,354 — 2,354 — Cash and cash equivalents 20 — 20 — Total $ 5,334 $ 2,960 $ 2,374 $ — December 31, 2020 Fair Value Level 1 Level 2 Level 3 Common stock $ 1,562 $ 1,562 $ — $ — Mutual funds 2,202 2,022 — — Corporate / government bonds 982 — 982 — Cash and cash equivalents 10 — 10 — Total $ 4,756 $ 3,584 $ 992 $ — Plan contributions are made and the actuarial present value of accumulated Plan benefits are reported based on certain assumptions pertaining to interest rates, inflation rates and employee demographics, all of which are subject to change. Due to uncertainties inherent in the estimation and assumption process, it is at least reasonably possible that changes in these estimates and assumptions in the near term would be material to the consolidated financial statements. The Company generally funds accrued pension cost based on minimum Employee Retirement Income Security Act funding requirements. Benefit payments are anticipated to be as follows: 2022 $ 372 2023 374 2024 371 2025 371 2026 371 2027 - 2031 1,850 401(k) Plan The Company has 401(k) savings plan for salaried and non-salaried employees. Participation in the plan is optional. The Company matches employee contributions up to 3.5 % each pay period. The Company made matching contributions of $ 2,579 , $ 1,997 , and $ 1,141 for the years ended December 31, 2021, 2020, and 2019, respectively. The Company had accrued $725 for Company match as of December 31, 2021, which is expected to be paid by the second quarter of 2022.

Share-based Payment Arrangement [Abstract]
EQUITY-BASED COMPENSATION PLANS	13. EQUITY-BASED COMPENSATION PLANS In 2021, the Company adopted the 2021 Omnibus Incentive Plan (the “2021 Plan”), which provides for the grant of restricted stock awards, incentive and nonqualified stock options, and other share based awards to employees, directors and non-employees. The 2021 Plan authorized 8,850,000 new shares of the Company’s common stock to be available for award grants. As of December 31, 2021, 6,797,101 shares of common stock remained available for future issuance under the 2021 Plan. Stock Options Stock option grants have an exercise price at least equal to the market value of the underlying common stock on the date of grant, have ten-year terms, and vest ratably over three years of continued employment. In general, vested options expire if not exercised at termination of service. On July 16, 2021, the Company granted 1,394,008 options to purchase shares of the Company’s common stock to key employees. These stock options had a weighted-average grant date fair value $ 3.88 per share and remain outstanding and unvested as of December 31, 2021. Compensation expense for stock options is recorded based on straight-line amortization of the grant date fair value over the requisite service period. A summary of stock option activity during the year ended December 31, 2021 is presented below: Weighted Average Weighted Remaining Aggregate Outstanding Average Contractual Intrinsic Value Stock Options Exercise Price Term (in millions) December 31, 2020 — $ — Granted 1,394,008 10.50 Forfeited ( 7,034 ) 10.50 December 31, 2021 1,386,974 $ 10.50 2.54 $ 3.5 As of December 31, 2021, there was $ 4,582 of unrecognized compensation cost related to unvested stock options that is expected to be recognized over a remaining weighted-average period of 2.5 years. The fair value of each stock option granted on July 16, 2021 was estimated on the grant date using the Black-Scholes option pricing model with the following assumptions: Weighted-average expected term 6.0 Expected volatility 40.3 % Expected dividend $ — Risk-free interest rate 0.94 % The expected term has been estimated using a simplified method, which calculates the expected term as the mid-point between the vesting date and the contractual life of the awards since the Company does not have an extended history of actual exercises. The expected dividend yield is assumed to be zero since the Company has never paid dividends and does not have current plans to pay any dividends. The risk-free interest rate is based on yields of U.S. Treasury securities with maturities similar to the expected term of the options. Expected volatility is based on an evenly weighted blend of implied volatility and historical volatility of publicly-traded peer companies since the Company has limited historical volatility. Restricted Stock Units Restricted stock units (“RSUs”) vest ratably over one to three years from the anniversary of the Closing Date, or July 16, 2021, and expire ten years from the date of grant. The fair value of a RSU at the grant date is equal to the market price of the Company’s common stock on the grant date. On September 23, 2021, the Company granted 658,891 RSUs to key employees and directors. These RSUs had a weighted-average grant date fair value of $ 12.06 per unit and remain outstanding and unvested as of December 31, 2021. Compensation expense for RSUs is recorded based on amortization of the grant date fair market value over the period the restrictions lapse. A summary of RSU activity during the year ended December 31, 2021 is presented below: Unvested Restricted Stock Units Weighted Number of Average Grant Shares Date Fair Value December 31, 2020 — $ - Granted 658,891 12.06 Forfeited ( 2,406 ) 12.06 December 31, 2021 656,485 $ 12.06 As of December 31, 2021, there was $ 6,875 of unrecognized compensation cost related to unvested RSUs that is expected to be recognized over a remaining weighted average period of 2.3 years. Profit Interest Units The Holley Stockholder has authorized an incentive pool of 41.4 million units of Parent that its management has the right to grant, which are designated as PIUs. Holley Stockholder grants certain employees of the Company PIU's, which are a special type of limited liability company equity unit that allows the recipient to potentially participate in a future increase in the value of the Company. PIUs are issued for no consideration and generally provide for vesting over the requisite service period, subject to the recipient remaining an employee of the Company through each vesting date. During 2021, the Holley Stockholder granted 6,546 PIUs that contained both time-based vesting criteria and performance-based vesting criteria related to the attainment of specified levels of return for certain other investors in Parent and the occurrence of certain events. The weighted-average grant date fair value of the PIUs granted in 2021 with performance-based vesting criteria was $ 1.25 and is being expensed over the requisite service period. During 2020 and 2019, the Holley Stockholder granted 4,507 and 2,967 PIUs, respectively, that contained certain performance vesting criteria related to the attainment of specified levels of return for certain other investors in Parent and the occurrence of certain events. The weighted-average grant date fair value of these performance based PIUs was $ 0.27 and $ 0.24 for grants in 2020 and 2019, respectively. No expense has been recorded for the 2020 or 2019 grants, as meeting the necessary performance conditions for vesting is not considered probable. Compensation expense related to PIUs is recorded based on the grant date fair value over the requisite service period. The table below summarizes the PIU activity for the years ended December 31, 2021, 2020 and 2019: Profit Interest Units Weighted Outstanding Average Grant Units Date Fair Value December 31, 2018 27,925 $ 0.27 Granted 3,906 0.25 December 31, 2019 31,831 0.27 Granted 5,932 0.28 Forfeited ( 2,193 ) 0.27 December 31, 2020 35,570 0.27 Granted 8,445 1.31 Forfeited ( 2,921 ) 0.30 December 31, 2021 41,094 $ 0.50 As of December 31, 2021, 2020 and 2019, the amount of unvested PIUs was 34,302 , 32,383 and 30,323 , respectively, with a weighted average grant date fair value of $ 0.48 , $ 0.26 and $ 0.28 as of December 31, 2021, 2020 and 2019, respectively. For the years ended December 31, 2021, 2020 and 2019, 3,629 , 1,679 and 1,508 PIUs were fully vested, respectively, with a total grant-date fair value of $ 3,069 , $ 487 and $ 437 in 2021, 2020 and 2019, respectively. As of December 31, 2021, there was $ 9,637 of total unrecognized compensation cost related to unvested time-based PIUs that is expected to be recognized over a remaining weighted-average period of 1.6 years. The fair value of PIUs is estimated on the grant date with the following assumptions: For the years ended December 31, 2021 December 31, 2020 December 31, 2019 Weighted-average expected term 2.0 3.4 4.1 Expected volatility 55.0 % 72.5 % 72.5 % Expected dividend $ — $ — $ — Risk-free interest rate 0.3 % 0.3 % 1.5 % PIUs are measured at the estimated fair value on the measurement date, which is typically the grant date. The fair value of PIUs is estimated using the Black-Scholes option pricing model. Determining the fair value of PIUs at the grant date is affected by estimates involving inherent uncertainties, as well as assumptions regarding a number of other complex and subjective variables. These variables include the fair value of the equity unit classes, value adjustments for a reduction in marketability, expected unit price volatility over the expected term of the units, unit redemption and cancellation behaviors, risk-free interest rates and expected dividends. The expected term has been estimated based on the contractual terms, vesting schedules and expectations of future unit holder behavior. The expected dividend yield is assumed to be zero since the Company has never paid dividends and does not have current plans to pay any dividends. The risk-free interest rate is based on yields of U.S. Treasury securities with maturities similar to the expected term of the options for each option group. As the Parent is a private company and does not have a trading history for its equity units, the expected price volatility for the equity units is estimated by taking the average historical price volatility for industry peers. Industry peers, which the Company has designated, consist of several public companies in the industry similar in size, stage of life cycle and financial leverage. Compensation Expense Equity-based compensation expense included the following components: For the years ended December 31, 2021 December 31, 2020 December 31, 2019 Stock options $ 824 $ — $ — Restricted stock units 1,070 — — Profit interest units 3,069 487 437 All equity-based compensation expense is recorded in selling, general and administrative costs in the consolidated statements of comprehensive income.

DESCRIPTION OF THE BUSINESS, BA

DESCRIPTION OF THE BUSINESS, BASIS OF PRESENTATION, AND SUMMARY ACCOUNTING POLICIES (Policies)	12 Months Ended
	Dec. 31, 2021
Accounting Policies [Abstract]
Emerging Growth Company Status	Emerging Growth Company Status Section 102(b)(1) of the Jumpstart Our Business Startups Act of 2012 (“JOBS Act”), exempts emerging growth companies from being required to comply with new or revised financial accounting standards until private companies are required to comply with the new or revised financial accounting standards. The JOBS Act provides that a company can elect to opt out of the extended transition period and comply with the requirements that apply to non-emerging growth companies but any such election to opt out is irrevocable. The Company is an emerging growth company, and, as such, has elected to take advantage of the benefits of the extended transition period for new or revised financial accounting standards.
Risks and Uncertainties	Risks and Uncertainties COVID-19 has adversely impacted global supply chain and general economic conditions. The Company has experienced disruptions and higher costs in manufacturing, supply chain, logistical operations, and shortages of certain Company products in distribution channels. The full extent of the impact of the COVID-19 pandemic on the Company's business and operational and financial performance and condition is currently uncertain and will depend on many factors outside the Company's control, including but not limited to the timing, extent, duration and effects of the virus and any of its mutations, the utilization and effectiveness of treatments and vaccines, the imposition of effective public safety and other protective measures, the further impact of COVID-19 on the global economy and demand for the Company's products and services. Should the COVID-19 pandemic, including variants such as Delta and Omicron, not improve or worsen, or if the Company's attempt to mitigate its impact on its supply chain, operations and costs is not successful, the Company's business, results of operations, financial condition and prospects may be adversely affected.
Basis of Presentation	Basis of Presentation The accompanying consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America ("U.S. GAAP" or “GAAP”) and include the accounts of the Company and its wholly-owned subsidiaries. All significant intercompany transactions and accounts have been eliminated in consolidation.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates. These estimates require the use of judgment as future events and the effect of these events cannot be predicted with certainty. The estimates will change as new events occur, as more experience is acquired and as more information is obtained. The Company evaluates and updates assumptions and estimates on an ongoing basis and may consult outside experts to assist as considered necessary.
Cash and Cash Equivalents	Cash and Cash Equivalents Cash and cash equivalents include cash and deposits with financial institutions with original maturities less than 90 days. The Federal Deposit Insurance Corporation insures financial institution deposits up to $ 250 . The Company maintains deposits exceeding $250 in certain accounts at financial institutions. At December 31, 2021 and 2020, the Company had cash in foreign bank accounts of $ 5,765 and $ 4,607 , respectively.
Accounts Receivable and Allowance for Credit Losses	Accounts Receivable and Allowance for Credit Losses Accounts receivable represent amounts due from customers in the ordinary course of business. The receivables are stated at the amount management expects to collect. The Company is subject to risk of loss from uncollectible receivables in excess of its allowance. The Company maintains an allowance for credit losses for estimated losses from customers’ inability to make required payments. In order to estimate the appropriate level of this allowance, the Company analyzes historical bad debts, customer concentrations, current customer credit worthiness, current economic trends and changes in customer payment patterns. Accounts are written off when management determines the account is uncollectable. Interest is not charged on past due accounts.
Inventory Valuation	Inventory Valuation The Company's inventories are stated at the lower of cost or net realizable value using the first-in, first-out (FIFO) method. Adjustments to reduce the cost of inventory to its net realizable value are made, if required, for estimated excess, obsolescence or impaired balances.
Segments	Segments The Company's operations are managed and reported to its Chief Executive Officer (“CEO”), the Company’s chief operating decision maker, on a consolidated basis. The CEO assesses performance and allocates resources based on the consolidated results of operations. Under this organizational and reporting structure, the Company has one reportable segment.
Goodwill	Goodwill Goodwill represents the excess of purchase price over the fair value of the net assets of businesses acquired. On an annual basis or whenever events or changes in circumstances indicate the carrying value of goodwill may have been impaired, the Company may perform a qualitative assessment to determine if it is more likely than not that the fair value of the reporting unit is less than its carrying amount, including goodwill. If the Company determines that the fair value of the reporting unit is less than its carrying amount or elects not to perform a qualitative assessment, it will perform a quantitative analysis; otherwise, no further evaluation is necessary. For the quantitative impairment assessment, the Company compares the fair value of the reporting unit to its carrying value, including goodwill. The Company determines the fair value of the reporting unit based on a weighting of income and market approaches. If the fair value of the reporting unit exceeds the carrying value of the net assets assigned to that unit, goodwill is not impaired and no further testing is performed. If the carrying value of the net assets assigned to the reporting unit exceeds the fair value of the reporting unit, then the Company will recognize a loss equal to the excess, limited to the total amount of goodwill allocated to that reporting unit. Impairments, if any, are charged directly to earnings. In 2021, the Company performed a qualitative assessment and did not identify any indicators of impairment. No impairment charges have been incurred during 2021, 2020, or 2019.
Intangible Assets Other Than Goodwill	Intangible Assets Other Than Goodwill Tradenames acquired in certain business combinations were determined to have indefinite useful lives and are not amortized, but instead are tested for impairment on an annual basis and when facts and circumstances indicate that the carrying values of the assets may be impaired. If such review indicates an asset’s carrying value may not be recoverable, an impairment loss is recognized for the excess of the carrying value over the fair value of the asset. As part of separate business acquisitions, the Company’s customer relationships, technology and certain tradenames were identified as definite-lived intangible assets. The customer relationship intangible assets are being amortized over a ten to twenty-five year life based on the attrition rate of customers. The technology intangible assets are being amortized over a five to fourteen year life based on the lifecycle of previous technology. The tradenames are being amortized over a fifteen to twenty year life based on the estimated life of the tradename.
Property, Plant and Equipment	Property, Plant and Equipment Property, plant and equipment acquired in various acquisitions have been recorded at fair value. All other property, plant and equipment is recorded at cost. Depreciation and amortization are provided for using the straight-line method over the estimated useful lives of the assets. Estimated useful lives for new property, plant and equipment additions are seven years to twenty-five years for buildings and improvements and three to ten years for machinery and equipment. Maintenance, repairs, and betterments which do not enhance the value of or increase the life of the assets are expensed as incurred.
Debt Issuance Costs	Debt Issuance Costs Debt issuance costs are being amortized using the effective interest method over the term of the related debt. As of December 31, 2021 and 2020 unamortized debt issuance costs were $ 13,264 and $ 16,684 , respectively, and are included as a reduction of debt. In connection with the Company's refinancing of its existing credit facility in 2021, a loss on the early extinguishment of debt of $ 13,650 was recognized for the write-off of unamortized debt issuance costs. Additionally, the Company paid $ 13,413 in original issue discount and issuance costs related to the new credit facility. Amortization expense for debt issuance costs was $ 3,182 , $ 3,092 , and $ 3,097 in 2021, 2020 and 2019, respectively, which is included in interest expense in the accompanying consolidated statements of comprehensive income (loss).
Self-Insurance	Self-Insurance The Company is self-insured for employee medical and prescription drug benefits up to certain stop loss coverage amounts. The Company accrues an estimate for unpaid claims, as well as incurred but not reported claims, based upon the Company’s claim experience and expectations of future claim activity. The resulting liability and expense are reflected as a component of accrued expenses, cost of sales and selling, general and administrative expenses in the accompanying consolidated balance sheets and consolidated statements of comprehensive income (loss), respectively.
Revenue Recognition	Revenue Recognition The Company recognizes revenue with customers when control of the promised goods transfers to the customer. This generally occurs when the product is shipped to the customer. Revenue is recorded at the amount of consideration the Company expects to be entitled to in exchange for the delivered goods, which includes an estimate of variable consideration, expected returns, or refunds when applicable. The Company estimates variable consideration, such as sales incentives, by using the most likely amount approach, which considers the single most likely amount from a range of possible consideration amounts. Estimates of variable consideration result in an adjustment to the transaction price such that it is probable that a significant reversal of cumulative revenue would not occur in the future. Sales incentives and allowances are recognized as a reduction to revenue at the time of the related sale. Revenue is recorded net of sales tax. Shipping and handling fees billed to customers are included in net sales, while costs of shipping and handling are included in selling, general and administrative costs. For more information about the Company’s revenue from contracts with customers, refer to Note 9 Revenue. Customer Sales Incentives Sales incentives provided take the form of either sales discounts or rebates and are treated as a reduction of net sales. The Company also maintains a cooperative advertising program with its customers and provides sales incentives to the extent of the estimated value of advertising provided by the customer on behalf of the Company. The costs incurred under the cooperative advertising program are included as a reduction of net sales. Sales Returns Estimated sales returns and allowances are recorded as a charge against gross sales in the period in which the related sales are recognized, net of returns to stock. The Company allows customers to return products when certain Company-established criteria are met. The Company estimates sales returns based primarily upon actual historical returns, planned product discontinuances, and promotional sales. Returned products, which are recorded as inventories, are valued at the lower of cost or net realizable value. The physical condition and marketability of the returned products are the major factors considered in estimating realizable value.
Income Taxes	Income Taxes Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred 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 recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. The Company recognizes income tax positions only if those positions are “more likely than not” of being sustained upon examination by taxing authorities. Recognized income tax positions are measured at the largest amount that is greater than 50% likely of being realized. Changes in recognition or measurement are reflected in the period in which the change in judgment occ urs. The Company recognizes interest on liabilities for uncertain tax positions in interest expense and would recognize penalties, if any, in operating expenses in its consolidated income statements. The Company has no amounts accrued for such interest or penalties as of December 31, 2021 and 2020. Th e Company files income tax returns in the U.S. federal jurisdiction and various foreign and state jurisdictions. As of December 31, 2021 and 2020, the Company did no t have any unrecognized tax benefits. The statute of limitations remains open for U.S. federal income tax examinations for years ende d December 31, 2018 through December 31, 2020. U.S. state jurisdictions have statues of limitations generally ranging from three to eight years . The Company does no t expect the total amount of unrecognized tax benefits to sign ificantly change in the next 12 months.
Impairment or Disposal of Long-Lived Assets	Impairment or Disposal of Long-Lived Assets The Company accounts for long-lived assets, including intangible assets subject to amortization, in accordance with the provisions that require long-lived assets, such as property and equipment, be reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to the sum of undiscounted net cash flows expected to be generated by the asset. If the carrying amount of an asset exceeds its estimated future cash flows, an impairment charge is recognized by the amount by which the carrying amount of the asset exceeds the fair value of the asset. Assets to be disposed of are reported at the lower of the carrying amount or fair value less costs to sell.
Advertising	Advertising Advertising production costs are expensed the first time the advertising takes place. Total advertising expenses were $ 6,299 , $ 4,379 , and $ 3,921 for the years ended December 31, 2021, 2020, and 2019, respectively. Advertising costs are classified as a component of selling, general and administrative costs in the accompanying consolidated statements of comprehensive income (loss).
Research and Development Costs	Research and Development Costs Research, development, pre-production and start-up costs related to both present and future products are expensed as incurred. Such costs amount to $ 28,280 , $ 23,483 , and $ 20,630 for the years ended December 31, 2021, 2020, and 2019, respectively.
Other Comprehensive Income (Loss)	Other Comprehensive Income (Loss) Comprehensive loss encompasses all changes in stockholder’s equity and includes net income, change in the foreign currency translation adjustment and minimum pension liability. The Company’s accumulated other comprehensive loss shown on the consolidated balance sheets as of December 31, 2021 and 2020 consists of minimum pension loss of $ 302 and $ 690 , respectively, and foreign currency translation adjustments of $( 46 ) and $( 16 ) , respectively.
Foreign Currencies	Foreign Currencies The functional currency of the Company’s Italian subsidiary is the Euro. Assets and liabilities of foreign operations are translated using period end exchange rates. Revenue and expenses are translated using average exchange rates during each period reported. Translation gains are reported in accumulated other comprehensive loss as a component of shareholders equity and were $ 30 and $ 16 as of December 31, 2021 and 2020, respectively. The Company recognizes foreign currency transaction gains (losses) on certain assets and liabilities. These transaction (gains) losses are reported in other expense in the consolidated statements of comprehensive income (loss) and were $ 44 , $( 284 ) , and $( 27 ) for the years ended December 31, 2021, 2020 and 2019, respectively.
Warrants	Warrants The Company reviews the terms of warrants to purchase its common stock to determine whether warrants should be classified as liabilities or stockholders' equity in its consolidated balance sheet. In order for a warrant to be classified in stockholders' equity, the warrant must be (a) indexed to the Company's equity and (b) meet the conditions for equity classification in Accounting Standards Codification ("ASC") Subtopic 815-40, Derivatives and Hedging-Contracts in an Entity's Own Equity. If a warrant does not meet the conditions for equity classification, it is carried in the consolidated balance sheet as a warrant liability measured at fair value, with subsequent changes in the fair value of the warrant recorded in the consolidated statements of comprehensive income as a non-operating expense. If a warrant meets both conditions for equity classification, the warrant is initially recorded in additional paid-in capital on the consolidated balance sheet, and the amount initially recorded is not subsequently re-measured at fair value.
Equity-Based Compensation	Equity-Based Compensation The Company accounts for equity-based awards granted to employees and nonemployees under the fair value method prescribed by ASC Subtopic 718-10, Stock Compensation. Equity-based compensation cost is measured based on the estimated grant date fair value of the award and is recognized as expense over the requisite service period (generally the vesting period). The Company accounts for forfeitures as they occur. The fair value of stock options is estimated using the Black Scholes option-pricing model. Restricted stock units are valued at the stock price on the grant date. The fair value of profit interest units ("PIUs") granted by Holley Parent Holdings, LLC (the “Holley Stockholder” or “Parent”) is estimated based on the Company’s estimated equity value for each unit class at the time of granting using the Black-Scholes option-pricing model, discounted to reflect market considerations for illiquidity.
Earnings per Share	Earnings per Share Earnings per share is computed by dividing net income or loss available to common stockholders by the weighted average number of common shares outstanding for the period. Diluted earnings per share is computed by giving effect to all potential dilutive common stock equivalents outstanding for the period. The dilutive effect of these potential common shares is reflected in diluted earnings per share by application of the treasury stock method.
Fair Value Measurements	Fair Value Measurements Fair value is defined as the price that would be received for sale of an asset or paid for transfer of a liability, in an orderly transaction between market participants at the measurement date. In determining fair value, the Company utilizes valuation techniques that maximize the use of observable inputs and minimizes the use of unobservable inputs to the extent possible. The inputs used to measure fair value are prioritized based on a three-level hierarchy, which are defined as follows: Level 1 – Quoted prices (unadjusted) for identical assets or liabilities in active markets that the entity has the ability to access as of the measurement date. Level 2 – Significant other observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data. Level 3 – Significant unobservable inputs that reflect a company’s own assumptions about the assumptions that market participants would use in pricing an asset or liability.
Derivative Financial Instruments	Derivative Financial Instruments The Company evaluates its financial instruments to determine if such instruments are derivatives or contain features that qualify as embedded derivatives in accordance with ASC Topic 815, “Derivatives and Hedging”. For derivative financial instruments that are accounted for as liabilities, the derivative instrument is initially recorded at its fair value on the grant date and is then re-valued at each reporting date, with changes in the fair value reported in the statements of operations. Derivative liabilities are classified on the balance sheet as current or non-current based on whether or not net-cash settlement or conversion of the instrument could be required within 12 months of the balance sheet date.
Recent Accounting Standards	Recent Accounting Pronouncements Accounting Standards Recently Adopted The FASB issued 2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. The amendments in ASU 2016-13 will provide more decision-useful information about the expected credit losses on financial instruments and other commitments to extend credit held by a reporting entity at each reporting date. The ASU is effective for annual reporting periods beginning after December 15, 2022. The Company early adopted the standard in 2020. There was no material impact of adopting this guidance on its financial statements. Accounting Standards Not Yet Adopted In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) which requires lessees to recognize right-of-use assets, representing their right to use the underlying asset for the lease term, and lease liabilities on the balance sheet for all leases with terms greater than 12 months. The Company has substantially completed its preparation for the adoption of this new accounting standard. This included assessing the completeness of our lease arrangements, evaluating practical expedients and accounting policy elections, and executing changes to our business process. ASU 2016-02 is effective for the Company beginning January 1, 2022. The standard requires the use of a modified retrospective transition approach, which includes a number of optional practical expedients that entities may elect to apply. The Company expects to elect certain practical expedients, including the package of practical expedients to not reassess prior conclusions related to contracts containing leases, lease classification and initial direct costs, and is evaluating the other practical expedients available under the guidance. The Company also plans to elect the optional transition method that will give companies the option to use the effective date as the date of initial application on transition, and as a result, we will not adjust our comparative period financial information or make the new required lease disclosures for periods before the effective date. The Company anticipates the adoption of this new standard will result in an increase of approximately 3 percent of total assets and approximately 4 percent of total liabilities on our consolidated balance sheet. We do not expect the new standard to have a material impact on the Company's consolidated statement of income or consolidated statement of cash flows. While we are substantially complete with the process of quantifying the impacts that will result from applying the new guidance, our assessment will be finalized during the first quarter of 2022. In August 2018, the FASB issued ASU 2018-14, Compensation – Retirements Benefits – Defined Benefit Plans – General (Subtopic 715-20). The ASU is effective for the Company for annual reporting periods beginning after December 15, 2021 with early adoption permitted. This guidance should be applied on a retrospective basis to all periods presented. The ASU will update disclosure requirements for employers that sponsor defined benefit pension or other post retirement plans. The Company is in the process of terminating its defined benefit pension plan and does not expect this guidance to have a significant impact on its financial statements or related disclosures. In December 2019, the FASB issued ASU 2019-12, Simplifying the Accounting for Income Taxes (Topic 740) which is intended to simplify various aspects related to accounting for income taxes. This ASU is effective for the Company for annual reporting periods beginning after December 15, 2021 and interim periods therein, with early adoption permitted. The ASU removes certain exceptions to the general principles in Topic 740 and also clarifies and amends existing guidance to improve consistent application. The Company does not expect the adoption of this ASU to have a material impact on its financial statements. In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848). The ASU provides optional expedients and exceptions for applying GAAP to contracts, hedging relationships, and other transactions affected by reference rate reform if certain criteria are met. Adoption of the provisions of ASU 2020-04 are optional and are effective from March 12, 2020 through December 31, 2022. As of December 31, 2021, the Company did not adopt any expedients or exceptions under ASU 2020-04. The Company will continue to evaluate the impact of ASU 2020-04 and whether it will apply the optional expedients and exceptions. In August 2020, the FASB issued ASU 2020-06, Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity (Subtopic 470-20). The ASU is effective for the Company for annual reporting periods beginning after December 15, 2023 and interim periods therein, with early adoption permitted as of the beginning of the Company's annual fiscal year. The ASU includes amendments to the guidance on convertible instruments and the derivative scope exception for contracts in an entity’s own equity and simplifies the accounting for convertible instruments which include beneficial conversion features or cash conversion features by removing certain separation models in Subtopic 470-20. Additionally, the ASU requires entities to use the “if-converted” method when calculating diluted earnings per share for convertible instruments. When adopted, the ASU will result in changes in the fair value of its public warrants being recognized through equity rather than through the statement o f income. The Company plans to early adopt the standard as of January 1, 2022.
