Organization, Consolidation and Presentation of Financial Statements [Abstract]
ORGANIZATION AND NATURE OF OPERATIONS	NOTE 1 — ORGANIZATION AND NATURE OF OPERATIONS Nature of Operations Alta Equipment Group Inc. and its subsidiaries (“Alta” or the “Company”) is engaged in the sale, service, and rental of material handling, construction, and environmental processing equipment in the states of Michigan, Illinois, Indiana, Ohio, New York (including New York City in our Material Handling segment), Virginia, Massachusetts (including Boston), Maine, New Hampshire, Vermont, Connecticut, Nevada, and Florida as well as the Canadian provinces of Quebec and Ontario. Unless the context otherwise requires, the use of the terms “the Company”, “we”, “us,” and “our” in these notes to the consolidated financial statements refers to Alta Equipment Group Inc. and its consolidated subsidiaries. Basis of Presentation The accompanying consolidated financial statements include the consolidated accounts of the Company and have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”). All intercompany transactions and balances have been eliminated in the preparation of the consolidated financial statements. Reclassification and correction Subsequent to the issuance of the December 31, 2021 financial statements, the Company’s management re-evaluated the presentation of its line of credit and concluded that it is more appropriately reflected as a long-term liability in the Company’s Consolidated Balance Sheets. As a result, the "Line of credit, net" as of December 31, 2021 has been restated to reflect such presentation. The correction resulted in an increase to long-term liabilities of $ 98.4 million and a corresponding decrease in current liabilities of the same amount as of December 31, 2021. The Company has concluded that this correction was not material to the previous periods.

Accounting Policies [Abstract]
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	NOTE 2 — SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Use of Estimates The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Estimates are based on assumptions that we believe are reasonable under the circumstances. Due to the inherent uncertainty involved with estimates, actual results may differ. Refer to Critical Accounting Policies and Estimates within Item 7 herein for more information on items in the consolidated financial statements we consider require significant estimation or judgment. Inventory Valuation Inventories are stated at the lower of cost or net realizable value. Cost is determined by specific identification for equipment and a weighted-average method for parts. Net realizable value is the estimated selling price in the ordinary course of business less reasonably predictable costs of completion, disposal, and transportation. Included in new and used inventory is equipment that is currently on short-term lease to customers. The Company mainly transfers equipment from inventory into rental fleet based on the management’s determination of the highest and best use of the equipment. This inventory is carried at the cost of the equipment less any accumulated depreciation. Property and Equipment Property and equipment are recorded at cost and depreciated over their estimated useful lives using the straight-line method excluding certain categories of our rental equipment, specifically in what we determine to be rent-to-sell equipment categories. The rent-to-sell categories are depreciated on a percentage of rental revenue realized on the asset, or a unit of activity method of depreciation. The Company believes that the unit of activity method on these categories of equipment more appropriately matches revenue and depreciation expense versus a straight-line methodology, as asset utilization can vary month to month especially in our northern geographies where seasonality is a factor. In rent-to-rent product categories, where asset utilization is more stable, like in our Material Handling segment, we use a straight-line depreciation methodology, where estimated useful lives can range from five to ten years. The Company capitalizes expenditures for equipment, leasehold improvements, and rental fleet. Expenditures for repairs, maintenance, and minor renewals are expensed as incurred. Expenditures for betterments and major renewals that significantly extend the useful life of the asset are capitalized in the period incurred. When equipment is sold or otherwise disposed of, the cost and related accumulated depreciation are removed from the Consolidated Balance Sheets, with any resulting gain or loss being reflected in income from operations. Intangible Assets Intangible assets with a finite life consist of customer and supplier relationships, non-compete agreements, tradenames, and internal use software and are carried at cost less accumulated amortization. During the fourth quarter of 2021, the Company shortened the remaining useful lives of some tradename intangible assets resulting in accelerated amortization in the fourth quarter of 2021 and thereafter given our rebranding efforts on recent acquisitions. The estimated useful lives of the finite-lived intangible assets are as follows: Estimated Customer and supplier relationships 9 – 10 years Other intangibles 2 – 5 years Evaluation of Goodwill Impairment Goodwill is tested for impairment annually or more frequently if an event or circumstance indicates that an impairment loss may have been incurred. Application of the goodwill impairment test requires judgment, including: the identification of reporting units; assignment of assets and liabilities to reporting units; assignment of goodwill to reporting units; and determination of the fair value of each reporting unit. We estimate the fair value of our reporting units (which are our reportable segments) using a discounted cash flow methodology under an income approach, corroborated with the results of a market approach which analyzes the enterprise value (market capitalization plus interest-bearing liabilities) and operating metrics (e.g., earnings before interest, taxes, depreciation and amortization expenses) of companies engaged in the same or similar line of business that we deem comparable to our business and compare those metrics to those of the Company. We make judgments regarding the comparability of publicly traded companies engaged in similar businesses and based our judgments on factors such as size, growth rates, profitability, business model, and risk. We believe the combination of these valuation approaches yields the most appropriate evidence of fair value. Inherent in our preparation of cash flow projections are assumptions and estimates derived from a review of our operating results, business plans, expected growth rates, cost of capital, and tax rates. We also make certain forecasts about future economic conditions, interest rates, and other market data. Many of the factors used in assessing fair value are outside the control of management, and these assumptions and estimates may change in future periods. Changes in assumptions or estimates could materially affect the estimate of the fair value of a reporting unit, and therefore could affect the likelihood and amount of potential impairment. Financial Accounting Standards Board ("FASB") guidance permits entities to first assess qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount as a basis for determining whether it is necessary to perform the quantitative analysis. While the Company does not believe a qualitative assessment would have triggered the required quantitative assessment, the Company bypassed the optional qualitative assessments for each reporting unit and performed quantitative assessments at October 1, 2022, 2021 and 2020. We review goodwill for impairment by comparing the fair value of each of our reporting units’ net assets to their respective carrying value. If the carrying value of a reporting unit’s net assets is less than its fair value, we do not recognize an impairment. If the carrying amount of a reporting unit’s net assets is greater than its fair value, we recognize a goodwill impairment for the amount of the excess of the net assets over the fair value, not to exceed the book value of goodwill. Our annual goodwill impairment testing conducted as of October 1, 2022, 2021 and 2020 indicated that all our reporting units had estimated fair values which exceeded their respective carrying amounts. Based on the results of the tests, there was no goodwill impairment. Evaluation of Long-lived Asset Impairment (excluding goodwill) Our long-lived assets principally consist of rental equipment, leases, property and equipment, and other intangible assets excluding goodwill. We review our long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. In reviewing for impairment, the carrying value of such assets is compared to the expected undiscounted future pre-tax cash flows expected from the use of the assets and their eventual disposition. If such cash flows are not sufficient to support the asset’s recorded value, an impairment loss is recognized to reduce the carrying value of the asset to its estimated fair value. The determination of future cash flows as well as the estimated fair value of long-lived and intangible assets involves significant estimates and judgment on the part of management. Our estimates and assumptions may prove to be inaccurate due to factors such as changes in economic conditions, expected asset utilization levels, our business activity levels or other changing circumstances. In support of our review for indicators of impairment, we perform a review of our long-lived assets at the reportable segment level to conclude whether indicators of impairment exist associated with our long-lived assets, including our rental and non-rental equipment and right-of-use assets. Based on our most recently completed reviews in the fourth quarter 2022, there were no indications of impairment associated with our long-lived assets (excluding goodwill). Business Combinations We allocate the fair value of purchase consideration to the tangible and intangible assets acquired and liabilities assumed, and based on their estimated fair values on the acquisition date. Management develops estimates based on assumptions as part of the purchase price allocation process to value the assets acquired and liabilities assumed as of the acquisition date. These estimates are inherently uncertain and are subject to refinement. As a result, during the preliminary purchase price measurement period, which may be up to one year from the acquisition date, the Company may record adjustments to the assets acquired and liabilities assumed, with the corresponding offset to goodwill. Upon the conclusion of the measurement period, the Company will record any subsequent adjustments to the assets acquired or liabilities assumed in operating expenses in the period in which the adjustments are determined. Revenue Recognition Revenues are recognized when control of promised goods or services is transferred to customers in an amount that reflects the consideration the business expects to be entitled to in exchange for those goods or services. Control is transferred when the customer has the ability to direct the use of and obtain the benefits from the goods or services. The Company’s revenues accounted for under Topic 606 - Revenues from Contracts with Customers ("Topic 606") generally have the transaction price fixed and clearly stated in the customer contracts. Substantially all the Company’s sales agreements contain performance obligations satisfied at a point in time when control is transferred to the customer, generally at the time of delivery to, or pick-up by, the customer. For agreements with multiple performance obligations, which are infrequent, judgment is required to determine whether performance obligations specified in these agreements are distinct and should be accounted for as separate revenue transactions for recognition purposes. In these types of agreements, the Company generally allocates sales prices to each distinct performance obligation based on the observable selling price. Payment terms vary by the type and location of the customer and the products or services offered. Generally, the time between when revenue is recognized and payment is due is not significant. The Company does not evaluate whether the selling price includes a financing interest component for contracts that are less than a year or if payment is expected to be received less than a year after the good or service has been provided. Sales and other taxes collected from customers and remitted to government authorities are accounted for on a net basis and, therefore, are excluded from revenue. Shipping and handling costs are treated as fulfillment costs and are included in cost of revenue. The Company’s revenues do not include material amounts of variable consideration under Topic 606. Contracts with customers do not generally result in significant obligations associated with returns, refunds, or warranties. See Note 3, Revenue Recognition, for more information. Leases The Company adopted Topic 842 - Leases ("Topic 842") and all related amendments effective for the annual reporting period ended December 31, 2021, with an effective date of January 1, 2021, using the modified retrospective method. The Company as Lessee: We determine whether an arrangement is a lease at the inception of the arrangement based on the terms and conditions in the contract. A contract contains a lease if there is an identified asset and we have the right to control the asset for a period of time in exchange for consideration. Lease right-of-use (“ROU”) assets represent our right to use an individual asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. Lease ROU assets and liabilities are recognized at the commencement date for leases with terms greater than 12 months and meet our capitalization threshold based upon the present value of the remaining future minimum lease payments over the lease term. As most of our leases do not provide the lessor’s implicit rate, we use our incremental borrowing rate (“IBR”) at the commencement date in determining the present value of future lease payments by utilizing a fully collateralized rate for a fully amortizing loan with the same term as the lease. The Company applies the portfolio approach for the IBR on its leases based upon similar lease term and payments. The lease ROU asset also includes lease payments made in advance of lease commencement and excludes lease incentives. Operating lease expense for minimum lease payments is recognized on a straight-line basis over the lease term. The Company has lease agreements with lease and non-lease components. For real estate leases, these components are accounted for as a single lease component. For all equipment leases excluding vehicles the lease and non-lease components are accounted for as a single lease component. For vehicle leases, these components are accounted for separately. Variable lease expenses include payments based upon changes in a rate or index, such as consumer price indexes, variable payments on non-lease components related to leases that we account for as a single lease component, and charges fluctuating based on the usage of the leased asset. Short-term lease expenses include leases with terms at lease commencement of 12 months or less and no purchase option reasonably certain to be exercised, including leases with a duration of one month or less. Low-value lease expense includes leases with terms at lease commencement of greater than 12 months but do not meet our capitalization threshold, which is consistent with our property and equipment capitalization threshold. The Company’s lease agreements do not contain any material residual value guarantees or material restrictive covenants; however, there are certain lease agreements that include guaranteed purchase obligations for lift trucks. A ROU asset is subject to the same impairment guidance as assets categorized as property and equipment. As such, any impairment loss on ROU assets is presented in the same manner as an impairment loss recognized on other long-lived assets. The Company reviewed its lease ROU assets for impairment and determined that none of the assets were impaired during the years ended December 31, 2022 and 2021. Operating leases are included in Operating lease right-of-use assets, net, Current operating lease liabilities and Long-term operating lease liabilities on the Company’s Consolidated Balance Sheets. Finance leases are included in Property and equipment, net, Current portion of long-term debt, and Finance lease obligations, net of current portion on the Company’s Consolidated Balance Sheets. See Note 12, Leases, related to the required lease disclosures. The Company as Lessor: See Revenue Recognition within Note 2 and Note 3, Revenue Recognition, for more information. Income Taxes The Company was a newly formed corporation in 2020 for income tax purposes. Alta Enterprises, LLC was historically and remains a partnership for federal income tax purposes, with each partner being separately taxed on its share of taxable income (loss). There is no federal income tax expense (benefit) reflected in the Company’s financial statements for any period prior to the reverse recapitalization on February 14, 2020. As most of the activity resides in Alta Enterprises, LLC, the income tax impact to the Company represents the current income tax calculated at the consolidated return level, (“Alta Equipment Group Inc. and Subsidiaries”), and the deferred impact of the interest in the lower tier partnership. As it relates to being a consolidated return filer, and considering the operating entity is a 100 % owned partnership, the Company uses the guidance in Topic 740 - Income Taxes ("Topic 740") asset and liability method of accounting for income taxes, under which deferred tax assets and liabilities are recognized for the future tax consequences of (i) temporary differences between the financial statement carrying amounts and the tax bases of existing assets and liabilities and (ii) operating loss and tax credit carryforwards. Deferred income tax assets and liabilities are based on enacted tax rates applicable to the future period when those temporary differences are expected to be recovered or settled. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in income in the period the rate change is enacted. Deferred income tax assets are subject to valuation allowance considerations to recognize only amounts that are more likely than not to be ultimately realized. In accordance with Topic 740, we review the likelihood that we will realize the benefit of deferred tax assets and estimate whether recoverability of our deferred tax assets is “more likely than not”. In determining whether a valuation allowance is needed, on a quarterly basis we evaluate historical operating results, the existence of cumulative losses in the most recent fiscal years, expectations for future pretax operating income within the carryback or carryforward periods provided for in the tax law for each applicable tax jurisdiction, the time period over which our temporary differences will reverse and the implementation of feasible and prudent tax planning strategies. A cumulative loss in recent years is considered a significant piece of negative evidence that is difficult to overcome in assessing the need for a valuation allowance. Fair Value of Financial Instruments Fair value is defined as the amount that would be received for selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Accounting standards establish a fair value hierarchy which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The FASB fair value measurement guidance established a fair value hierarchy that prioritizes the inputs used to measure fair value. We assess the inputs used to measure fair value using the three-tier hierarchy. The three broad levels of the fair value hierarchy are as follows: • Level 1 — Quoted prices (unadjusted) in active markets for identical assets or liabilities • Level 2 — Quoted prices for similar assets and liabilities in active markets or inputs that are observable for the asset or liability, either directly or indirectly • Level 3 — Unobservable inputs for which little or no market data exists, therefore requiring a company to develop its own assumptions In instances where the determination of the fair value measurement is based on inputs from different levels of the fair value hierarchy, the level in the fair value hierarchy within which the entire fair value measurement falls is based on the lowest level input that is significant to the fair value measurement in its entirety. The estimated fair values of derivative financial instruments are valued using widely accepted valuation techniques including discounted cash flow analysis on the expected cash flows of each derivative. The fair value of interest rate caps is determined using the market-standard methodology of discounting the future expected cash receipts which would occur if floating interest rates rise above the strike rate of the caps. The floating interest rates used in the calculation of projected receipts on the caps are based on the period to maturity and an expectation of future interest rates derived from observable market interest rate curves and volatilities. The inputs used in the valuation of interest rate caps fall within Level 2 of the fair value hierarchy. Translation of Foreign Currency Assets and liabilities of our foreign subsidiaries that have a functional currency other than U.S. dollars are translated into U.S. dollars using exchange rates at the balance sheet date. Revenues and expenses are translated at average exchange rates effective during the year. Foreign currency translation gains and losses are included as a component of accumulated other comprehensive income (loss) ("AOCI") within the Consolidated Balance Sheets. New Accounting Pronouncements Pronouncements Not Yet Adopted Financial Instruments — Credit Losses In June 2016, the FASB issued ASU 2016-13, Financial Instruments — Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments . This standard prescribes an impairment model (known as the current expected credit loss (“CECL”) model) that is based on expected losses rather than incurred losses. Under the new guidance, an entity recognizes as an allowance its estimate of expected credit losses, which is intended to result in the timely recognition of losses. Under the CECL model, entities will estimate credit losses over the entire contractual term of the instrument from the date of initial recognition of the financial instrument. Measurement of expected credit losses is to be based on relevant forecasts that affect collectability. The scope of financial assets within the CECL model is broad and includes trade receivables from certain revenue transactions and certain off-balance sheet credit exposures. Different components of the guidance require modified retrospective or prospective adoption. As amended by ASU 2019-10, the ASU 2016-13 is effective for the annual reporting period beginning January 1, 2023. ASU 2016-13 will only be applicable to the Company’s receivables from revenue transactions, or trade receivables, except those arising from rental revenues as ASU 2016-13 does not apply to receivables arising from operating leases. The new guidance, limited to our non-operating lease trade receivables, will not have a material impact on the Company's consolidated financial statements or existing internal controls.

Revenue from Contract with Customer [Abstract]
REVENUE RECOGNITION	NOTE 3 — REVENUE RECOGNITION We recognize revenue in accordance with two different accounting standards: 1) Topic 606, 2) Topic 842 in 2022 and 2021, and Topic 840 - Leases ("Topic 840") in 2020 . Disaggregation of Revenues The following table summarizes the Company’s disaggregated revenues as presented in the Consolidated Statements of Operations for the years ended December 31, 2022, 2021 and 2020 by revenue type and by the applicable accounting standard. Year Ended Year Ended Year Ended Topic 842 Topic 606 Total Topic 842 Topic 606 Total Topic 840 Topic 606 Total Revenues: New and used equipment sales $ — $ 817.2 $ 817.2 $ — $ 568.8 $ 568.8 $ — $ 410.3 $ 410.3 Parts sales — 234.8 234.8 — 178.5 178.5 — 129.6 129.6 Service revenue — 206.6 206.6 — 165.5 165.5 — 128.5 128.5 Rental revenue 180.1 — 180.1 155.5 — 155.5 118.8 — 118.8 Rental equipment sales — 133.1 133.1 — 144.5 144.5 — 86.4 86.4 Total revenues $ 180.1 $ 1,391.7 $ 1,571.8 $ 155.5 $ 1,057.3 $ 1,212.8 $ 118.8 $ 754.8 $ 873.6 The Company believes that the disaggregation of revenues from contracts to customers as summarized above, together with the discussion below, depicts how the nature, amount, timing and uncertainty of its revenues and cash flows are affected by economic factors. See Note 19, Segments, for further information. Leases revenues (Topic 842 in 2022 and 2021 and Topic 840 in 2020) New and used equipment sales: The Company enters into various equipment sale transactions with certain customers, whereby customers purchase equipment from the Company and then lease the equipment to a third party. In some cases, the Company provides a guarantee to repurchase the equipment back at the end of the lease term between the customer and third-party lessee at a set residual amount set forth in the initial sales contract or pay the customer for the deficiency, if any, between the sale proceeds received for the equipment and the guaranteed minimum resale value. The Company is precluded from recognizing a sale of equipment when it is obligated or has an option to repurchase or guarantees the resale value of the equipment to the customer for contracts determined to be operating leases. For these arrangements, because the Company generally receives the full amount of the consideration at the beginning of the arrangement, the Company initially records deferred revenue for the amount received and recognizes revenue on a pro-rata basis over the term of the contract under Topic 842 and Topic 840. Deferred revenue, with respect to the aforementioned sale transactions, represents the net proceeds upon the equipment’s initial transfer. These amounts, excluding the guaranteed residual value, are recognized into rental revenue on a pro-rata basis over the leased contract period up to the first exercise date of the guarantee. At December 31, 2022 and 2021, the total deferred revenue relating to these various equipment sale transactions amounted to $ 3.0 million and $ 2.9 million, respectively. The Company also recognized a liability for its guarantee to repurchase the equipment at the residual amounts of $ 7.0 million and $ 7.2 million as of December 31, 2022 and 2021. Rental revenue: Owned equipment rentals represent revenues from renting equipment. The Company accounts for these rental contracts as operating leases. The Company recognizes revenue from equipment rentals in the period earned, regardless of the timing of billing to customers. A rental contract includes rates for daily, weekly or monthly use, and rental revenues are earned on a daily basis as rental contracts remain outstanding. Because the rental contracts can extend across multiple reporting periods, the Company records unbilled rental revenues and deferred rental revenues at the end of each reporting period. Unbilled rental revenues are included as a component of “Accounts receivable, net” on the Consolidated Balance Sheets. Rental equipment is also purchased outright (“rental conversions”). Rental revenue and revenue attributable to rental conversions, are recognized in “Rental revenue” and “Rental equipment sales” on the Consolidated Statements of Operations, respectively. The Company also recognizes deferred revenue related to rental agreements. The adoption of Topic 842 in 2021 did not have a material impact on how lease revenues are recorded by the Company. Revenues from contracts with customers (Topic 606) Accounting for the different types of revenues pursuant to Topic 606 are discussed below. Substantially all of the Company’s revenues under Topic 606 are recognized at a point in time rather than over time. New and used equipment sales: With the exception of bill-and-hold arrangements and project-based revenues, the Company’s revenues from the sale of new and used equipment are recognized at the time of delivery to, or pick-up by, the customer, which is when the customer obtains control of the promised good. Under bill-and-hold arrangements, revenue is recognized when all configuration work is complete and the equipment has been set aside for final shipment, at which point the Company has determined control has been transferred. The bill-and-hold arrangements primarily apply to sales when physical shipment of heavy equipment to the customer is prohibited by law (e.g. frost laws) or requested by the customer due to their inability to arrange freight simultaneous to the satisfaction of the performance obligations, both are limited circumstances. The customer equipment sold under a bill-and-hold arrangement is physically separated from Company inventory and that equipment cannot be used by the Company or sold to another customer. The Company does not offer material rights of return. Revenue recognized from bill-and-hold agreements totaled $ 15.6 million for the year ended December 31, 2022. Project-based revenues, as referred to herein, are contracts with customers where the Company provides design and build solutions, automated equipment installation and system integration and installation and set-up of warehouse management systems and related hardware and software support services. This revenue is recognized as the performance obligations are satisfied over time using the cost-to-cost input method, based on contract costs incurred to date to total estimated contract costs. The Company recognizes deferred revenue with respect to automated equipment installation and system integration services, service maintenance contracts. Deferred revenue with respect to service sales represents the unearned portion of fees related to guaranteed maintenance contracts for customers covering equipment previously purchased. These amounts are recognized based on an estimated rate at which the services are provided over the life of the contract. The Company recognized approximately $ 77.5 million, $ 55.9 million and $ 14.9 million in project-based revenues for the years ended 2022, 2021 and 2020 respectively. Parts sales: Revenues from the sale of parts are recognized at the time of pick-up by the customer for over-the-counter sales transactions. For parts that are shipped to a customer, the Company elected to use a practical expedient of Topic 606 and treat such shipping activities as fulfillment costs, thereby recognizing revenues at the time of shipment. The Company does not offer material rights of return. Service revenue: The Company records service revenue primarily from guaranteed maintenance and periodic maintenance contracts with customers. The Company recognizes periodic maintenance service revenues at the time such services are completed, which is when the control of the promised services is transferred over to the customer. The Company recognizes guaranteed maintenance service revenues over-time using an input method of costs incurred to estimated costs over the life of the related contract, typically three to five years . Revenue recognized from guaranteed maintenance contracts totaled $ 21.4 million, $ 18.8 million and $ 16.4 million for the years ended December 31, 2022, 2021 and 2020 respectively. The Company also records service revenue from warranty contracts whereby the Company performs service on behalf of the Original Equipment Manufacturer (“OEM”) or third-party warranty provider. Rental equipment sales: The Company also sells rental equipment from our rental fleet. These sales are recognized at the time of delivery to, or pick-up by, the customer, which is when the customer obtains control of the promised good. In some cases, certain rental agreements contain a rental purchase option, whereby the customer has an option to purchase the rented equipment during the term of the rental agreement. Revenues from the sale of rental equipment are recognized at the time the rental purchase option agreement has been approved and signed by both parties, as the equipment is already in the customer’s possession under the previous rental agreement, and therefore control has been transferred as title has been transferred. Contract costs The Company does not recognize assets associated with the incremental costs of obtaining a contract with a customer that the Company expects to recover (for example, a sales commission). Most of the Company’s revenue is recognized at a point in time or over a period of one year or less, and the Company has used the practical expedient that allows it to recognize the incremental costs of obtaining a contract as an expense when incurred if the amortization period of the asset that the Company otherwise would have recognized is one year or less. The amount of the costs associated with the revenue recognized over a period of greater than one year is insignificant. Receivables and contract assets and liabilities The Company has contract assets and contract liabilities associated with project-based contracts with customers. Contract assets are fulfilled contractual obligations prior to receivables being recognizable for project-based revenue. Contract assets as of December 31, 2022 and 2021 were $ 3.6 million and $ 6.0 million, respectively. Revenue from recurring support services is recognized ratably over the contract period. The deferred revenue (contract liabilities) includes the unearned portion of project-based revenue. Total deferred revenue relating to automated equipment installation and system integration services, service maintenance contracts and equipment rental agreements as of December 31, 2022 and 2021 was $ 16.0 million and $ 16.5 million, respectively. In addition, deferred revenue includes the unearned portion of revenue related to guaranteed maintenance service contracts for customers covering equipment previously purchased. These amounts are recognized based on an estimated rate at which the services are provided over the life of the contract. Deferred revenue also includes the net proceeds upon sale of equipment with certain guaranteed purchase obligations. In total, deferred revenue as of December 31, 2022 and 2021 was $ 19.0 million and $ 19.4 million, respectively. For the years ended December 31, 2022 and 2021, the Company recognized revenue of $ 12.6 million and $ 8.5 million, respectively, from the prior year ending deferred revenue balance. We believe concentration of credit risk with respect to our receivables is limited because our customer base is comprised of a large number of geographically diverse customers.

FLOOR PLANS	NOTE 9 — FLOOR PLANS Floor Plan — First Lien Lender On April 1, 2021, the Company entered into a Sixth Amended and Restated Floor Plan First Lien Credit Agreement ("Floor Plan Credit Agreement") by and among Alta Equipment Group, Inc. and the other credit parties named therein, and the lender JP Morgan Chase Bank, N.A., as Administrative Agent. Under the Floor Plan Credit Agreement, the Company has a first lien floor plan facility (the "First Lien Floor Plan Facility") with its first lien lender to primarily finance new inventory. In connection with the acquisition of the stock of YIT, on July 6, 2022 the Company amended its Floor Plan Credit Agreement to increase the maximum borrowing capacity by $ 10.0 million from $ 50.0 to $ 60.0 million. The interest cost for the First Lien Floor Plan Facility is SOFR plus an applicable margin. The First Lien Floor Plan Facility is collateralized by substantially all assets of the Company. As of December 31, 2022, the Company had an outstanding balance on our First Lien Floor Plan Facility of $ 58.6 million, excluding unamortized debt issuance costs. The effective interest rate at December 31, 2022 was 7.0 % . As of December 31, 2021, the Company had an outstanding balance on our First Lien Floor Plan Facility of $ 30.6 million, excluding unamortized debt issuance costs. The effective interest rate at December 31, 2021 was 2.8 % . The Company routinely sells equipment that is financed under the First Lien Floor Plan Facility. When this occurs the payable under the First Lien Floor Plan Facility related to the financed equipment being sold becomes due to be paid. Original Equipment Manufacturer (“OEM”) Captive Lenders and Suppliers’ Floor Plans The Company has floor plan financing facilities with several OEM captive lenders and suppliers (the “OEM Floor Plan Facilities”, and together with the First Lien Floor Plan Facility, collectively the “Floor Plan Facilities”) for new and used inventory and rental equipment, each with borrowing capacities ranging from $ 0.1 million to $ 102.0 million. Primarily, the Company utilizes the OEM Floor Plan Facilities for purchases of new equipment inventories. Certain OEM Floor Plan Facilities provide for up to twelve-months interest only or deferred payment periods. In addition, certain OEM Floor Plan Facilities regularly provide for interest and principal free payment terms. The Company routinely sells equipment that is financed under OEM Floor Plan Facilities. When this occurs the payable under the OEM Floor Plan Facilities related to the financed equipment being sold becomes due to be paid. With the recent acquisitions, some of the Company’s OEM Floor Plan Facilities were amended to include new locations and new entities. The OEM Floor Plan Facilities are secured by the equipment being financed, and contain certain operating company guarantees. The interest cost is SOFR plus an applicable margin. The effective rates, excluding the favorable effect of interest-free periods, as of December 31, 2022 ranged from 6.8 % to 9.2 % . As of December 31, 2022 and December 31, 2021, the Company had an outstanding balance on the OEM Floor Plan Facilities of $ 198.3 million and $ 124.3 million, respectively. The total aggregate amount of financing under the Floor Plan Facilities cannot exceed $ 350 million at any time. The total outstanding balance under the Floor Plan Facilities as of December 31, 2022 and December 31, 2021, was $ 256.9 million and $ 154.9 million, respectively, excluding unamortized debt issuance costs. For the years ended December 31, 2022, 2021 and 2020, the Company recognized interest expense associated with new equipment financed under its Floor Plan Facilities of $ 2.7 million, $ 1.7 million, and $ 2.3 million, respectively.

LONG-TERM DEBT	NOTE 10 — LONG-TERM DEBT Line of Credit — First Lien Lender On April 1, 2021, the Company entered into a Sixth Amended and Restated ABL First Lien Credit Agreement (the “Amended and Restated ABL Credit Agreement”) by and among Alta Equipment Group Inc. and the other credit parties named therein, the lenders named therein, JP Morgan Chase Bank, N.A., as Administrative Agent, and the syndication agents and documentation agent named therein, superseding and replacing the Fifth Amended and Restated ABL First Lien Credit Agreement. Under the Amended and Restated ABL Credit Agreement, the Company has an asset based revolving line of credit (the “ABL Facility”) with its first lien holder with advances on the line being supported by eligible accounts receivable, parts, and otherwise unencumbered new and used equipment inventory and rental equipment. In connection with the acquisition of YIT, on July 6, 2022 the Company amended the ABL Facility by exercising $ 80.0 million of the $ 150.0 million accordion function increasing borrowing capacity from $ 350.0 million to $ 430.0 million, which includes a $ 35 million Canadian-denominated sublimit facility. The ABL Facility is collateralized by substantially all assets of the Company, and the interest cost is SOFR plus an applicable margin on the CB Floating Rate, depending on borrowing levels. As of December 31, 2022, the Company had an outstanding ABL Facility balance of $ 219.5 million, excluding unamortized debt issuance costs. The effective interest rate was 6.2 % at December 31, 2022. As of December 31, 2021, the Company had an outstanding ABL Facility balance of $ 100.7 million, excluding unamortized debt issuance costs. The effective interest rate was 2.3 % at December 31, 2021. Maximum borrowings under the Floor Plan Facilities and ABL Facility are limited to $ 780.0 million unless certain other conditions are met. The total amount outstanding as of December 31, 2022 and December 31, 2021, was $ 476.4 million and $ 255.6 million, exclusive of debt issuance and deferred financing costs of $ 2.1 million and $ 2.4 million, respectively. Senior Secured Second Lien Notes On April 1, 2021, the Company completed a private offering of Senior Secured Second Lien Notes (the “Notes”), for the purposes of, among other things, repayment and refinancing of a portion of the Company’s prior existing debt, reducing interest rate exposure and providing liquidity for financing of future growth initiatives. The Company sold $ 315.0 million of 5.625 % Notes which are due in 2026. The Notes are guaranteed (the “Guarantees” and, together with the Notes, the “Securities”) by the guarantors that are party thereto (the “Guarantors”) on a second lien, senior secured basis. The Notes were sold in a private placement in reliance on Rule 144A and Regulation S under the Securities Act of 1933, as amended, pursuant to a purchase agreement among the Company, the Guarantors, and J.P. Morgan Securities LLC, as representative of the initial purchasers. The Notes are guaranteed by each of our existing and future domestic subsidiaries that become a borrower or guarantor under our or the Guarantors’ indebtedness, including the Credit Agreements, as amended and restated concurrently with the closing of the Notes offering. The Notes and the Guarantees are secured, subject to certain exceptions and permitted liens, by second-priority liens on substantially all of our assets and the assets of the Guarantors that secure on a first-priority basis all of the indebtedness under our ABL Facility and the Floor Plan Facility and certain hedging and cash management obligations, including, but not limited to, equipment, fixtures, inventory, intangibles and capital stock of our restricted subsidiaries now owned or acquired in the future by us or the Guarantors. The Notes bear interest at the rate of 5.625 % per annum and will mature on April 15, 2026 . Interest on the Notes is payable in cash on April 15 and October 15 of each year, beginning on October 15, 2021. As of December 31, 2022, outstanding borrowings under the Notes were $ 311.2 million, which included $ 3.8 million deferred financing costs and original issue discounts. The effective interest rate on the Notes, taking into account the original issue discount, is 5.93 % . Term Loan On February 14, 2020, the Company entered into a Note Purchase Agreement for a second lien term loan (the “Term Loan”) in an aggregate principal amount of $ 155.0 million with a second-priority lien lender through syndication, with an initial maturity date of August 2025 . The term loan was payable, at the lender’s option, in quarterly installments of $ 1.9 million plus interest cost at SOFR plus 8 %. On April 1, 2021, in connection with the issuance of the new Notes, the Company repaid all of its outstanding obligations under the Term Loan, $ 147.3 million, completely discharging the Company of any further obligations to the lender. Extinguishment of Debt In the second quarter of 2021, and in connection with the repayment of the Term Loan, the Company recorded a loss on the extinguishment of debt in the amount of $ 11.9 million in the line item "Loss on extinguishment of debt" in its Consolidated Statements of Operations. This was in accordance with Topic 470-50 - Debt – Modifications and Extinguishments , as the transaction was determined to be an extinguishment of the existing debt and an issuance of new debt. The Company’s long-term debt consists of the following: December 31, December 31, 2022 2021 Line of credit $ 219.5 $ 100.7 High yield notes 315.0 315.0 Unamortized debt issuance costs ( 2.8 ) ( 3.3 ) Debt discount ( 3.0 ) ( 4.0 ) Finance leases 19.6 11.6 Total debt and finance leases $ 548.3 $ 420.0 Less: current maturities ( 4.2 ) ( 2.6 ) Long-term debt and finance leases, net $ 544.1 $ 417.4 As of December 31, 2022, the Company was in compliance with the financial covenants set forth in its debt agreements.

As of December 31, 2022, the Company recorded a $ 1.1 million liability which included $ 1.0 million related to present value of these minimum cash payments using a market participant discount rate and $ 0.1 million of imputed interest after a $ 0.8 million payment was made during 2022. As of December 31, 2021, the liability was $ 1.8 million.

Commitments and Contingencies Disclosure [Abstract]
CONTINGENCIES	NOTE 13 — CONTINGENCIES Guarantees As of December 31, 2022 and December 31, 2021, the Company was party to certain contracts in which it guarantees the performance of agreements with various third-party financial institutions. The terms of the guarantees range from 1 to 5 years. In the event of a default by a third-party lessee, the Company would be required to pay all or a portion of the remaining unpaid obligations as specified in the contract. The estimated exposure related to these guarantees was $ 1.5 million and $ 1.7 million at December 31, 2022 and December 31, 2021 , respectively. It is anticipated that the third parties will have the ability to repay the debt without the Company having to honor the guarantee; therefore, no amount has been accrued on the Consolidated Balance Sheets at December 31, 2022 and December 31, 2021, respectively. Legal Proceedings During the years ended December 31, 2022 and December 31, 2021, various claims and lawsuits, incidental to the ordinary course of our business, were pending against the Company. In the opinion of management, after consultation with legal counsel, resolution of these matters is not expected to have a material effect on the Company’s consolidated financial statements. Contractual Obligations The Company does not believe there are any off-balance sheet arrangements that have, or are reasonably likely to have, a material effect on the Company. As of December 31, 2022 and December 31, 2021 there was $ 4.9 million $ 3.4 million , respectively, in outstanding letters of credit issued in the normal course of business. These letters of credit reduce our available borrowings as disclosed in Note 10, Long-Term Debt.

Income Tax Disclosure [Abstract]
Income Taxes	NOTE 14 — INCOME TAXES The income tax provision (benefit) for the years ended December 31, 2022, 2021 and 2020 were calculated based upon the following components of income before income taxes: Year Ended December 31, 2022 2021 2020 U.S. income (loss) $ 9.0 $ ( 17.2 ) $ ( 30.6 ) Foreign income 1.6 — — Total income (loss) before taxes $ 10.6 $ ( 17.2 ) $ ( 30.6 ) The income tax provision (benefit) for the years ended December 31, 2022, 2021 and 2020 consisted of the following: Year Ended December 31, 2022 2021 2020 Current U.S. federal $ 1.9 $ — $ — U.S. state 0.6 — — Foreign — — — Deferred U.S. federal ( 0.7 ) 2.8 ( 5.0 ) U.S. state ( 0.8 ) 0.8 ( 1.6 ) Foreign 0.3 — — Total income tax expense (benefit) $ 1.3 $ 3.6 $ ( 6.6 ) For the years ended December 31, 2022, 2021 and 2020 the reconciliation between the income tax expense (benefit) computed by applying the statutory U.S. federal and state related income tax rate to the pre-tax loss before income taxes and total income tax expense (benefit) recognized in the consolidated financial statements was as follows: Year Ended December 31, 2022 2021 2020 Income tax expense (benefit) at statutory U.S. federal rate $ 2.2 $ ( 3.6 ) $ ( 4.3 ) Income tax benefit at statutory U.S. states rate, net ( 0.4 ) ( 0.6 ) ( 1.2 ) Permanent differences: Foreign rate differential 0.1 — — Officer's life insurance — — ( 1.7 ) Valuation allowance 0.8 7.6 — Fixed asset basis adjustments ( 1.6 ) — — Other 0.2 0.2 0.6 Total income tax expense (benefit) $ 1.3 $ 3.6 $ ( 6.6 ) The effective tax rate for the years ended December 31, 2022, 2021 and 2020 was 12.3 % , ( 20.9 )% and 31.9 % , respectively. The effective income tax rate in 2022 was primarily related to income tax expense associated with tax filing jurisdictions with no associated valuation allowance and 2021 was primarily due to the impact of the establishment of the valuation allowance against the deferred tax asset. The effective income tax rate in 2020 was primarily due to the impact of expenses and resulting tax losses associated with the reverse capitalization. The Company considers the undistributed earnings of its foreign subsidiaries to be indefinitely reinvested. The undistributed earnings of foreign subsidiaries and related unrecognized deferred tax liability are not material as of December 31, 2022. The Company will continue to evaluate its plans for reinvestment or repatriation of unremitted foreign earnings. If the Company determines that all or a portion of such foreign earnings are no longer indefinitely reinvested, the Company may be subject to foreign withholding taxes and U.S. state income taxes, beyond the one-time transition tax. The components of deferred tax assets and liabilities as of December 31, 2022 and 2021 were as follows: Year Ended December 31, 2022 2021 Deferred Tax Assets Net operating loss carryforwards $ 8.3 $ 10.8 Deferred revenue 0.7 0.7 Accounts receivable and inventories 6.0 4.3 Goodwill & intangibles 1.8 1.0 Accrued liabilities 6.0 3.4 Lease liability 35.2 29.5 Interest limitation carryforward 3.7 — Deferred payroll taxes and other (1) 1.8 2.4 Gross deferred tax assets $ 63.5 $ 52.1 Valuation allowance ( 8.8 ) ( 7.6 ) Deferred tax assets $ 54.7 $ 44.5 Deferred Tax Liabilities Property and equipment ( 25.3 ) ( 21.3 ) Prepaid expenses ( 1.5 ) ( 1.2 ) Lease right-of-use assets ( 34.3 ) ( 28.9 ) Gross deferred tax liabilities $ ( 61.1 ) $ ( 51.4 ) Deferred tax (liabilities) assets, net $ ( 6.4 ) $ ( 6.9 ) (1) Certain amounts in the prior year have been reclassified to conform with the presentation in the current year. This had no impact on the consolidated financial statements. For the years ended December 31, 2022 and 2021, the net change in the valuation allowance was increases of $ 1.2 million and $ 7.6 million, respectively. The valuation allowance increased in 2022 primarily due to the increases in deferred tax assets primarily related to interest limitation carryforward and accrued liabilities. The increase in 2021 was due to the establishment of the valuation allowance. The Company reviews the realizability of its deferred tax asset on a quarterly basis, or whenever events or changes in circumstances indicate that a review is required. In determining the requirement for a valuation allowance, the historical and projected financial results are considered, along with any other positive or negative evidence. All of the factors that the Company considers in evaluating whether and when to establish or release all or a portion of the deferred tax asset valuation allowance involves significant judgment. As of December 31, 2022 and 2021, the Company had federal net operating tax loss carryforwards of approximately $ 30.5 million and $ 42.7 million, respectively, which may be carried forward indefinitely and are eligible to offset 80 % of future taxable income. The Company also has state net operating loss carryforwards of approximately $ 32.2 million with varying carryforward expiration periods ranging from 2025 to 2041. We have established a valuation allowance fully offsetting the net operating losses that the Company does not expect to be realizable in the U.S. On March 27, 2020, the Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”) was enacted in response to the COVID-19 pandemic. The CARES Act, among other things, includes various income and payroll tax provisions, modifications to federal net operating loss rules and business interest deduction limitations. The CARES Act did not materially impact our effective tax rate for prior periods, although it will impact the timing of future cash payments for taxes. Under the CARES Act, as of December 31, 2022 and 2021, we have deferred employer payroll taxes of $ 0.6 million and $ 5.0 million, respectively. The Company has open tax years from 2019 through 2022 for U.S. federal and Canadian income taxes. The Company also files tax returns in numerous states for which various tax years are subject to examination and currently involved in audits. Typically states remain open for three years from filing, with the majority of the open years being 2019 to 2022.

Stock Based Compensation

Share-Based Payment Arrangement [Abstract]
STOCK BASED COMPENSATION	NOTE 15 — STOCK BASED COMPENSATION The Company’s plan is to have broad-based, long-term programs intended to attract and retain talented employees and align stockholder and employee interests. We calculated the fair value of the restricted stock units ("RSUs") and performance stock units ("PSUs") at grant date based on the closing market price of our common stock at the date of grant. The compensation expense is recognized on a straight-line basis over the requisite vesting period of the award. The number of PSUs granted depends on the Company's achievement of target performance goals, which may range from 0 % to 200 % of the target award amount. The PSUs vest ratably over three years including the one-year performance period . Upon vesting, each stock award is exchangeable for one share of the Company's common stock, with accrued dividends. The Company recognized total stock-based compensation expense of $ 2.7 million, $ 1.2 million and $ 3.6 million for the years ended December 31, 2022, 2021 and 2020 , respectively. Prior to 2020, the Company had implemented a Long-Term Equity Linked Incentive Plan (“the Plan”) for key employees. The purpose of the Plan was to retain and attract key employees with an opportunity to receive additional compensation in connection with a change in control of the company (“qualifying event”). The plan permitted the award of up to 15,686.28 incentive units and 7,843.14 appreciation rights. For the year ended December 31, 2020, the Company incurred $ 3.1 million of stock-based compensation expense as a result of vesting and extinguishment of the equity linked incentive plan as a result of the qualifying event on February 14, 2020. As of December 31, 2022, the total unrecognized compensation expense related to the non-vested portion of the Company's restricted stock awards was $ 1.9 million , which is expected to be recognized over a weighted average period of 1.4 years. As of December 31, 2022, the total unrecognized compensation expense related to the non-vested portion of the Company's performance stock awards was $ 3.9 million , which is expected to be recognized over a weighted average period of 1.9 years. The following table shows the number of restricted stock awards that were granted and vested during 2022: Restricted Stock Units Performance Stock Units Number of units Weighted average grant date fair value Number of units Weighted average grant date fair value Unvested units as of December 31, 2021 309,292 $ 9.71 — $ — Granted 125,599 11.82 424,538 12.14 Vested - issued ( 90,649 ) 9.24 — — Vested - unissued ( 55,976 ) 12.46 — — Unvested units as of December 31, 2022 288,266 $ 10.24 424,538 $ 12.14

Fair Value Disclosures [Abstract]
FAIR VALUE OF FINANCIAL INSTRUMENTS	NOTE 16 — FAIR VALUE OF FINANCIAL INSTRUMENTS The carrying value of financial instruments reported in the accompanying Consolidated Balance Sheets for Cash, Accounts receivable, Accounts payable, Accrued expenses and Other current liabilities approximate fair value due to the immediate or short-term nature or maturity of these financial instruments. The following is a description of the valuation methodologies used for assets and liabilities measured at fair value on a recurring basis: Debt Instruments The carrying value of the Company's debt instruments vary from their fair values. The fair values were determined by reference to transacted prices and quotes for these instruments and upon current borrowing rates with similar maturities, which are Level 2 fair value inputs. The estimated fair value, as well as the carrying value, of the Company's debt instruments as of December 31, 2022 and December 31, 2021 are shown below: December 31, 2022 December 31, 2021 Estimated aggregate fair value $ 521.0 $ 432.0 Aggregate carrying value (1) 554.1 427.3 (1) Total debt excluding the impact of unamortized debt discount and debt issuance costs. Contingent Consideration The contingent consideration liability represents the fair value of the future earn-out that the Company may be required to pay in conjunction with the acquisitions upon the achievement of certain performance milestones. The earn-out for the acquisitions is measured at fair value in each reporting period, based on Level 3 inputs, with any change to the fair value recorded in the Consolidated Statements of Operations. The following table sets forth, by level of hierarchy, the Company’s recurring measures at fair value as of December 31, 2022 and December 31, 2021, which are presented in “Other current liabilities” and “Other liabilities” on the Consolidated Balance Sheets: December 31, 2022 Level 1 Level 2 Level 3 Liabilities Contingent consideration $ — $ — $ 9.8 December 31, 2021 Level 1 Level 2 Level 3 Liabilities Contingent consideration $ — $ — $ 2.8 The following is a summary of changes to Level 3 instruments as of December 31, 2022 and December 31, 2021: Contingent Consideration Balance, January 1, 2021 $ 1.8 Acquisition of Ginop 0.9 Change in fair value 0.1 Balance, December 31, 2021 $ 2.8 Acquisitions 6.9 Changes in fair value 0.5 Payments ( 0.4 ) Balance, December 31, 2022 $ 9.8 The following table represents the Company’s Level 3 financial instruments, the valuation techniques used to measure the fair value of those financial instruments as of December 31, 2022 and 2021, respectively, and the significant unobservable inputs: Instrument Fair Value December 31, 2022 Fair Value December 31, 2021 Principal Valuation Technique Significant Unobservable Inputs Contingent consideration $ 9.8 $ 2.8 Probability weighted range of outcomes See above Derivative Financial Instruments In the normal course of business, we are exposed to market risk associated with changes in foreign currency exchange rates and interest rates. To manage a portion of these inherent risks, we may purchase certain types of derivative financial instruments based on management's judgment of the trade-off between risk, opportunity and cost. We do not hold or issue derivative financial instruments for trading or speculative purposes. The impact of hedge ineffectiveness was not significant in any of the periods presented. Currency Derivative Contracts From time to time, we use foreign currency forward contracts to reduce the effects of fluctuations in exchange rates relating to certain foreign currencies. We had currency forward contracts outstanding with a notional amount of $ 9.2 million at December 31, 2022 that hedge our exposure to changes in foreign currency exchange rates for certain inventory purchases through August 2023. The unrealized gain on the foreign currency forward contracts for the period ended December 31, 2022 was not material. The Company has determined the currency derivative contracts are based on Level 2 inputs reflecting quoted market inputs. Interest Rate Cap During November 2022, we entered into an interest rate cap through December 2025 to protect cash flows from the risks associated with interest payments from interest rate increases on variable rate debt. The interest rate cap was designated and qualified as a cash flow hedge. The premiums paid are recognized in income when paid from the effective date through the termination date. All changes in the value of the cap are deferred in AOCI and subsequently recognized in earnings in the period when the derivative contract settles. As of December 31, 2022 , we have a notional amount of $ 200.0 million hedged at a strike rate of 4.5 % on one-month SOFR. The unrealized loss and hedge ineffectiveness on the interest rate cap for the period ended December 31, 2022 were not material. The Company has determined fair value on the interest rate derivatives based on significant observable inputs (Level 2) reflecting quoted market prices for similar instruments from commercial banks and inputs other than quoted prices that are observable (forward curves, implied volatility, counterparty credit risks) at regularly intervals. The following table sets forth the Company’s derivative financial instruments measured at fair value as of December 31, 2022 and December 31, 2021, which were presented in “Other assets” and "Other current liabilities" on the Consolidated Balance Sheets: Derivatives designated as hedge Financial Statement Location December 31, 2022 December 31, 2021 Interest rate cap fair value Other assets $ 3.5 $ — Foreign currency contracts Other current liabilities 0.2 —

Retirement Benefits [Abstract]
UNION PENSION PLAN	NOTE 18 — UNION PENSION PLAN The Company contributes to various multiemployer defined benefit pension plans under collective bargaining agreements that cover certain union represented employees. These multiemployer plans generally provide retirement benefits to participants based on their service to contributing employers. The benefits are paid from assets held in trust for that purpose. Plan trustees typically are responsible for determining the level of benefits to be provided to participants as well as the investment of the assets and plan administration. Trustees are appointed in equal number by employers and the unions that are parties to the relevant collective bargaining agreements. Expense is recognized in connection with these plans as contributions are funded, in accordance with U.S. GAAP. The risks of participating in such plans are different from the risks of single-employer plans, in the following respects: (a) Assets contributed to a multiemployer plan by one employer may be used to provide benefits to employees of other participating employers; (b) If a participating employer ceases to contribute to the plan, the unfunded obligations of the plan may be borne by the remaining participating employers; and (c) If the Company ceases to have a continuing obligation to contribute to the multiemployer plan in which the Company had been a contributing employer, the Company may be required to pay to the plan an amount based on the underfunded status of the plan and on the history of the Company’s participation in the plan prior to the cessation of its obligation to contribute. The Company’s participation in multiemployer plans for the annual periods ended December 31, 2022, 2021 and 2020 is outlined in the table below. For each plan that is individually significant to the Company, the following information is provided: • The “Pension Protection Act Zone Status” available is for plan years that ended in 2022 and 2021. The zone status is based on information provided to the Company and other participating employers by each plan and is certified by the plan’s actuary. This indicates the funded status of the plan with the status indicated by the colors of green, yellow and red with green being the most funded and red being the least funded. • The “FIP/RP Status Pending/Implemented” column indicates whether a Funding Improvement Plan, as required under the Code to be adopted by plans in the “yellow” zone, or a Rehabilitation Plan, as required under the Code to be adopted by plans in the “red” zone, is pending or has been implemented as of the end of the plan year. • The “Surcharge Imposed” column indicates whether a surcharge was paid during the most recent annual period presented for the Company’s contributions to any plan in the red zone in accordance with the requirements of the Code. • The last column lists the expiration dates of the collective bargaining agreements with the Company. Certain plans have been aggregated in the All Other Multiemployer Pension Plans line in the following table, as the contributions to each of these plans are not individually material. None of our collective bargaining agreements require that a minimum contribution be made to these plans. There are no plans where the amount contributed by the Company represents more than 5 % of the total contributions to the plan for the years ended December 31, 2022, 2021 and 2020.

Segment Reporting [Abstract]
SEGMENTS	NOTE 19 — SEGMENTS The Company has two reportable segments: Material Handling and Construction Equipment. All other business activities, including Ecoverse, electric vehicles and corporate are included in "Corporate and Other". The Company’s segments are determined based on management structure, which is organized based on types of products sold, as described in the following paragraph. The operating results for each segment are reported separately to the Company’s Chief Executive Officer to make decisions regarding the allocation of resources, to assess the Company’s operating performance and to make strategic decisions. The Material Handling segment is principally engaged in operations related to the sale, service and rental of lift trucks and other material handling equipment in Michigan, Illinois, Indiana, New York (including New York City), Virginia and the New England region (including Boston) of the U.S. as well as Ontario and Quebec provinces of Canada. As of December 31, 2022, the Material Handling segment included the YIT acquisition and its related results since the acquisition during the third quarter. The Construction Equipment segment is principally engaged in operations related to the sale, service and rental of construction equipment in Michigan, Illinois, Indiana, Ohio, New York, Florida and the New England region (including Boston) of the U.S. The Company retains various unallocated expense items at the general corporate level, which the Company refers to as “Corporate and Other” in the table below. Corporate and Other holds corporate debt, our electric vehicle and environmental processing equipment business activity as well as other activity not directly attributable to our Material Handling and Construction Equipment segments. Corporate and Other incurs expenses associated with compensation (including stock-based compensation) of our directors, corporate officers and certain members of our shared-services leadership team, consulting and legal fees related to acquisitions and capital raising activities, corporate governance and compliance related matters, certain corporate development related expenses, interest expense associated with original issue discounts and deferred financing cost related to previous capital raises and a portion of the Company’s income tax provision. There is also intercompany elimination activity presented within the Corporate and Other segment.

Earnings Per Share [Abstract]
EARNINGS PER SHARE	NOTE 20 — EAR NINGS PER SHARE Basic earnings per share (“EPS”) is calculated by dividing net income by the weighted-average number of shares outstanding during the period. Diluted earnings per share is calculated by dividing net income by the weighted-average number of common shares outstanding, after giving effect to all dilutive potential common shares outstanding during the period. We include all common shares granted under our stock-based compensation plan which remain unvested (“restricted stock units”), in the number of shares outstanding for our diluted EPS calculations using the treasury method. Basic and diluted EPS for the year ended December 31, 2022, 2021 and 2020 were calculated as follows: Year Ended December 31, 2022 2021 2020 Basic net loss per share Net income (loss) available to common stockholders $ 6.3 $ ( 23.4 ) $ ( 24.0 ) Basic weighted average common shares outstanding 32,099,247 31,706,329 26,612,982 Basic net loss per share of common stock $ 0.20 $ ( 0.74 ) $ ( 0.90 ) Diluted loss per share Net income (loss) available to common stockholders $ 6.3 $ ( 23.4 ) $ ( 24.0 ) Basic weighted average common shares outstanding 32,099,247 31,706,329 26,612,982 Effect of dilutive securities: Effect of dilutive non-vested restricted stock units 202,416 — — Diluted weighted average common shares outstanding 32,301,663 31,706,329 26,612,982 Diluted net loss per share of common stock $ 0.20 $ ( 0.74 ) $ ( 0.90 ) Securities excluded from the calculation of diluted loss per share were approximately 174,000 and 90,000 for the years ended December 31, 2021 and 2020 , respectively, because the inclusion of such securities in the calculation would have been anti-dilutive.

Summary of Significant Accoun_2

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2022
Accounting Policies [Abstract]
Use of Estimates	Use of Estimates The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Estimates are based on assumptions that we believe are reasonable under the circumstances. Due to the inherent uncertainty involved with estimates, actual results may differ. Refer to Critical Accounting Policies and Estimates within Item 7 herein for more information on items in the consolidated financial statements we consider require significant estimation or judgment.
Inventory Valuation	Inventory Valuation Inventories are stated at the lower of cost or net realizable value. Cost is determined by specific identification for equipment and a weighted-average method for parts. Net realizable value is the estimated selling price in the ordinary course of business less reasonably predictable costs of completion, disposal, and transportation. Included in new and used inventory is equipment that is currently on short-term lease to customers. The Company mainly transfers equipment from inventory into rental fleet based on the management’s determination of the highest and best use of the equipment. This inventory is carried at the cost of the equipment less any accumulated depreciation.
Property and Equipment	Property and Equipment Property and equipment are recorded at cost and depreciated over their estimated useful lives using the straight-line method excluding certain categories of our rental equipment, specifically in what we determine to be rent-to-sell equipment categories. The rent-to-sell categories are depreciated on a percentage of rental revenue realized on the asset, or a unit of activity method of depreciation. The Company believes that the unit of activity method on these categories of equipment more appropriately matches revenue and depreciation expense versus a straight-line methodology, as asset utilization can vary month to month especially in our northern geographies where seasonality is a factor. In rent-to-rent product categories, where asset utilization is more stable, like in our Material Handling segment, we use a straight-line depreciation methodology, where estimated useful lives can range from five to ten years. The Company capitalizes expenditures for equipment, leasehold improvements, and rental fleet. Expenditures for repairs, maintenance, and minor renewals are expensed as incurred. Expenditures for betterments and major renewals that significantly extend the useful life of the asset are capitalized in the period incurred. When equipment is sold or otherwise disposed of, the cost and related accumulated depreciation are removed from the Consolidated Balance Sheets, with any resulting gain or loss being reflected in income from operations.
Intangible Assets	Intangible Assets Intangible assets with a finite life consist of customer and supplier relationships, non-compete agreements, tradenames, and internal use software and are carried at cost less accumulated amortization. During the fourth quarter of 2021, the Company shortened the remaining useful lives of some tradename intangible assets resulting in accelerated amortization in the fourth quarter of 2021 and thereafter given our rebranding efforts on recent acquisitions. The estimated useful lives of the finite-lived intangible assets are as follows: Estimated Customer and supplier relationships 9 – 10 years Other intangibles 2 – 5 years
Evaluation of Goodwill Impairment	Evaluation of Goodwill Impairment Goodwill is tested for impairment annually or more frequently if an event or circumstance indicates that an impairment loss may have been incurred. Application of the goodwill impairment test requires judgment, including: the identification of reporting units; assignment of assets and liabilities to reporting units; assignment of goodwill to reporting units; and determination of the fair value of each reporting unit. We estimate the fair value of our reporting units (which are our reportable segments) using a discounted cash flow methodology under an income approach, corroborated with the results of a market approach which analyzes the enterprise value (market capitalization plus interest-bearing liabilities) and operating metrics (e.g., earnings before interest, taxes, depreciation and amortization expenses) of companies engaged in the same or similar line of business that we deem comparable to our business and compare those metrics to those of the Company. We make judgments regarding the comparability of publicly traded companies engaged in similar businesses and based our judgments on factors such as size, growth rates, profitability, business model, and risk. We believe the combination of these valuation approaches yields the most appropriate evidence of fair value. Inherent in our preparation of cash flow projections are assumptions and estimates derived from a review of our operating results, business plans, expected growth rates, cost of capital, and tax rates. We also make certain forecasts about future economic conditions, interest rates, and other market data. Many of the factors used in assessing fair value are outside the control of management, and these assumptions and estimates may change in future periods. Changes in assumptions or estimates could materially affect the estimate of the fair value of a reporting unit, and therefore could affect the likelihood and amount of potential impairment. Financial Accounting Standards Board ("FASB") guidance permits entities to first assess qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount as a basis for determining whether it is necessary to perform the quantitative analysis. While the Company does not believe a qualitative assessment would have triggered the required quantitative assessment, the Company bypassed the optional qualitative assessments for each reporting unit and performed quantitative assessments at October 1, 2022, 2021 and 2020. We review goodwill for impairment by comparing the fair value of each of our reporting units’ net assets to their respective carrying value. If the carrying value of a reporting unit’s net assets is less than its fair value, we do not recognize an impairment. If the carrying amount of a reporting unit’s net assets is greater than its fair value, we recognize a goodwill impairment for the amount of the excess of the net assets over the fair value, not to exceed the book value of goodwill. Our annual goodwill impairment testing conducted as of October 1, 2022, 2021 and 2020 indicated that all our reporting units had estimated fair values which exceeded their respective carrying amounts. Based on the results of the tests, there was no goodwill impairment.
Evaluation of Long-lived Asset Impairment (excluding goodwill)	Evaluation of Long-lived Asset Impairment (excluding goodwill) Our long-lived assets principally consist of rental equipment, leases, property and equipment, and other intangible assets excluding goodwill. We review our long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. In reviewing for impairment, the carrying value of such assets is compared to the expected undiscounted future pre-tax cash flows expected from the use of the assets and their eventual disposition. If such cash flows are not sufficient to support the asset’s recorded value, an impairment loss is recognized to reduce the carrying value of the asset to its estimated fair value. The determination of future cash flows as well as the estimated fair value of long-lived and intangible assets involves significant estimates and judgment on the part of management. Our estimates and assumptions may prove to be inaccurate due to factors such as changes in economic conditions, expected asset utilization levels, our business activity levels or other changing circumstances. In support of our review for indicators of impairment, we perform a review of our long-lived assets at the reportable segment level to conclude whether indicators of impairment exist associated with our long-lived assets, including our rental and non-rental equipment and right-of-use assets. Based on our most recently completed reviews in the fourth quarter 2022, there were no indications of impairment associated with our long-lived assets (excluding goodwill).
Business Combinations	Business Combinations We allocate the fair value of purchase consideration to the tangible and intangible assets acquired and liabilities assumed, and based on their estimated fair values on the acquisition date. Management develops estimates based on assumptions as part of the purchase price allocation process to value the assets acquired and liabilities assumed as of the acquisition date. These estimates are inherently uncertain and are subject to refinement. As a result, during the preliminary purchase price measurement period, which may be up to one year from the acquisition date, the Company may record adjustments to the assets acquired and liabilities assumed, with the corresponding offset to goodwill. Upon the conclusion of the measurement period, the Company will record any subsequent adjustments to the assets acquired or liabilities assumed in operating expenses in the period in which the adjustments are determined.
Revenue Recognition	Revenue Recognition Revenues are recognized when control of promised goods or services is transferred to customers in an amount that reflects the consideration the business expects to be entitled to in exchange for those goods or services. Control is transferred when the customer has the ability to direct the use of and obtain the benefits from the goods or services. The Company’s revenues accounted for under Topic 606 - Revenues from Contracts with Customers ("Topic 606") generally have the transaction price fixed and clearly stated in the customer contracts. Substantially all the Company’s sales agreements contain performance obligations satisfied at a point in time when control is transferred to the customer, generally at the time of delivery to, or pick-up by, the customer. For agreements with multiple performance obligations, which are infrequent, judgment is required to determine whether performance obligations specified in these agreements are distinct and should be accounted for as separate revenue transactions for recognition purposes. In these types of agreements, the Company generally allocates sales prices to each distinct performance obligation based on the observable selling price. Payment terms vary by the type and location of the customer and the products or services offered. Generally, the time between when revenue is recognized and payment is due is not significant. The Company does not evaluate whether the selling price includes a financing interest component for contracts that are less than a year or if payment is expected to be received less than a year after the good or service has been provided. Sales and other taxes collected from customers and remitted to government authorities are accounted for on a net basis and, therefore, are excluded from revenue. Shipping and handling costs are treated as fulfillment costs and are included in cost of revenue. The Company’s revenues do not include material amounts of variable consideration under Topic 606. Contracts with customers do not generally result in significant obligations associated with returns, refunds, or warranties. See Note 3, Revenue Recognition, for more information.
Leases	Leases The Company adopted Topic 842 - Leases ("Topic 842") and all related amendments effective for the annual reporting period ended December 31, 2021, with an effective date of January 1, 2021, using the modified retrospective method. The Company as Lessee: We determine whether an arrangement is a lease at the inception of the arrangement based on the terms and conditions in the contract. A contract contains a lease if there is an identified asset and we have the right to control the asset for a period of time in exchange for consideration. Lease right-of-use (“ROU”) assets represent our right to use an individual asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. Lease ROU assets and liabilities are recognized at the commencement date for leases with terms greater than 12 months and meet our capitalization threshold based upon the present value of the remaining future minimum lease payments over the lease term. As most of our leases do not provide the lessor’s implicit rate, we use our incremental borrowing rate (“IBR”) at the commencement date in determining the present value of future lease payments by utilizing a fully collateralized rate for a fully amortizing loan with the same term as the lease. The Company applies the portfolio approach for the IBR on its leases based upon similar lease term and payments. The lease ROU asset also includes lease payments made in advance of lease commencement and excludes lease incentives. Operating lease expense for minimum lease payments is recognized on a straight-line basis over the lease term. The Company has lease agreements with lease and non-lease components. For real estate leases, these components are accounted for as a single lease component. For all equipment leases excluding vehicles the lease and non-lease components are accounted for as a single lease component. For vehicle leases, these components are accounted for separately. Variable lease expenses include payments based upon changes in a rate or index, such as consumer price indexes, variable payments on non-lease components related to leases that we account for as a single lease component, and charges fluctuating based on the usage of the leased asset. Short-term lease expenses include leases with terms at lease commencement of 12 months or less and no purchase option reasonably certain to be exercised, including leases with a duration of one month or less. Low-value lease expense includes leases with terms at lease commencement of greater than 12 months but do not meet our capitalization threshold, which is consistent with our property and equipment capitalization threshold. The Company’s lease agreements do not contain any material residual value guarantees or material restrictive covenants; however, there are certain lease agreements that include guaranteed purchase obligations for lift trucks. A ROU asset is subject to the same impairment guidance as assets categorized as property and equipment. As such, any impairment loss on ROU assets is presented in the same manner as an impairment loss recognized on other long-lived assets. The Company reviewed its lease ROU assets for impairment and determined that none of the assets were impaired during the years ended December 31, 2022 and 2021. Operating leases are included in Operating lease right-of-use assets, net, Current operating lease liabilities and Long-term operating lease liabilities on the Company’s Consolidated Balance Sheets. Finance leases are included in Property and equipment, net, Current portion of long-term debt, and Finance lease obligations, net of current portion on the Company’s Consolidated Balance Sheets. See Note 12, Leases, related to the required lease disclosures. The Company as Lessor: See Revenue Recognition within Note 2 and Note 3, Revenue Recognition, for more information.
Income Taxes	Income Taxes The Company was a newly formed corporation in 2020 for income tax purposes. Alta Enterprises, LLC was historically and remains a partnership for federal income tax purposes, with each partner being separately taxed on its share of taxable income (loss). There is no federal income tax expense (benefit) reflected in the Company’s financial statements for any period prior to the reverse recapitalization on February 14, 2020. As most of the activity resides in Alta Enterprises, LLC, the income tax impact to the Company represents the current income tax calculated at the consolidated return level, (“Alta Equipment Group Inc. and Subsidiaries”), and the deferred impact of the interest in the lower tier partnership. As it relates to being a consolidated return filer, and considering the operating entity is a 100 % owned partnership, the Company uses the guidance in Topic 740 - Income Taxes ("Topic 740") asset and liability method of accounting for income taxes, under which deferred tax assets and liabilities are recognized for the future tax consequences of (i) temporary differences between the financial statement carrying amounts and the tax bases of existing assets and liabilities and (ii) operating loss and tax credit carryforwards. Deferred income tax assets and liabilities are based on enacted tax rates applicable to the future period when those temporary differences are expected to be recovered or settled. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in income in the period the rate change is enacted. Deferred income tax assets are subject to valuation allowance considerations to recognize only amounts that are more likely than not to be ultimately realized. In accordance with Topic 740, we review the likelihood that we will realize the benefit of deferred tax assets and estimate whether recoverability of our deferred tax assets is “more likely than not”. In determining whether a valuation allowance is needed, on a quarterly basis we evaluate historical operating results, the existence of cumulative losses in the most recent fiscal years, expectations for future pretax operating income within the carryback or carryforward periods provided for in the tax law for each applicable tax jurisdiction, the time period over which our temporary differences will reverse and the implementation of feasible and prudent tax planning strategies. A cumulative loss in recent years is considered a significant piece of negative evidence that is difficult to overcome in assessing the need for a valuation allowance.
Fair Value of Financial Instruments	Fair Value of Financial Instruments Fair value is defined as the amount that would be received for selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Accounting standards establish a fair value hierarchy which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The FASB fair value measurement guidance established a fair value hierarchy that prioritizes the inputs used to measure fair value. We assess the inputs used to measure fair value using the three-tier hierarchy. The three broad levels of the fair value hierarchy are as follows: • Level 1 — Quoted prices (unadjusted) in active markets for identical assets or liabilities • Level 2 — Quoted prices for similar assets and liabilities in active markets or inputs that are observable for the asset or liability, either directly or indirectly • Level 3 — Unobservable inputs for which little or no market data exists, therefore requiring a company to develop its own assumptions In instances where the determination of the fair value measurement is based on inputs from different levels of the fair value hierarchy, the level in the fair value hierarchy within which the entire fair value measurement falls is based on the lowest level input that is significant to the fair value measurement in its entirety. The estimated fair values of derivative financial instruments are valued using widely accepted valuation techniques including discounted cash flow analysis on the expected cash flows of each derivative. The fair value of interest rate caps is determined using the market-standard methodology of discounting the future expected cash receipts which would occur if floating interest rates rise above the strike rate of the caps. The floating interest rates used in the calculation of projected receipts on the caps are based on the period to maturity and an expectation of future interest rates derived from observable market interest rate curves and volatilities. The inputs used in the valuation of interest rate caps fall within Level 2 of the fair value hierarchy.
Translation of Foreign Currency	Translation of Foreign Currency Assets and liabilities of our foreign subsidiaries that have a functional currency other than U.S. dollars are translated into U.S. dollars using exchange rates at the balance sheet date. Revenues and expenses are translated at average exchange rates effective during the year. Foreign currency translation gains and losses are included as a component of accumulated other comprehensive income (loss) ("AOCI") within the Consolidated Balance Sheets.
New Accounting Pronouncements	New Accounting Pronouncements Pronouncements Not Yet Adopted Financial Instruments — Credit Losses In June 2016, the FASB issued ASU 2016-13, Financial Instruments — Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments . This standard prescribes an impairment model (known as the current expected credit loss (“CECL”) model) that is based on expected losses rather than incurred losses. Under the new guidance, an entity recognizes as an allowance its estimate of expected credit losses, which is intended to result in the timely recognition of losses. Under the CECL model, entities will estimate credit losses over the entire contractual term of the instrument from the date of initial recognition of the financial instrument. Measurement of expected credit losses is to be based on relevant forecasts that affect collectability. The scope of financial assets within the CECL model is broad and includes trade receivables from certain revenue transactions and certain off-balance sheet credit exposures. Different components of the guidance require modified retrospective or prospective adoption. As amended by ASU 2019-10, the ASU 2016-13 is effective for the annual reporting period beginning January 1, 2023. ASU 2016-13 will only be applicable to the Company’s receivables from revenue transactions, or trade receivables, except those arising from rental revenues as ASU 2016-13 does not apply to receivables arising from operating leases. The new guidance, limited to our non-operating lease trade receivables, will not have a material impact on the Company's consolidated financial statements or existing internal controls.
