Condensed Consolidated Financial Information	NOTE 1. CONDENSED CONSOLIDATED FINANCIAL INFORMATION The condensed consolidated financial statements for the three and nine months ended September 30, 2023 and 2022 have not been audited, but in the opinion of management, all adjustments (consisting of normal recurring accruals, consolidating and eliminating entries) necessary for the fair presentation of the consolidated financial position, results of operations and cash flows of McGrath RentCorp (the “Company”) have been made. The accompanying unaudited condensed consolidated financial statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”). Certain information and note disclosures normally included in annual financial statements prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) have been condensed or omitted pursuant to those rules and regulations. The consolidated results for the three and nine months ended September 30, 2023, should not be considered as necessarily indicative of the consolidated results for the entire fiscal year. These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Company’s latest Annual Report on Form 10-K, filed with the SEC on February 22, 2023 for the year ended December 31, 2022 (the “2022 Annual Report”).

New Accounting Pronouncements	NOTE 2. NEW ACCOUNTING PRONOUNCEMENTS On March 27, 2023, the Financial Accounting Standards Board issued Accounting Standards Update ("ASU") 2023-01, Leases (Topic 842): Common Control Arrangements, which requires a lessee involved in a common control lease agreement to amortize leasehold improvements over the useful life of the improvements to the common control group, regardless of the lease term, as long as the lessee controls the use of the underlying asset. If the lessor obtains the right to control the use of the underlying asset through a lease with another entity not within the same control group, the amortization period cannot exceed the period of the common control group. Furthermore, the ASU requires the accounting for a transfer between entities under common control through an adjustment to equity when the lessee no longer controls the use of the underlying asset. The ASU is effective for fiscal years beginning after December 15, 2023. The Company does not expect the adoption of this ASU to have a material impact on the Company's consolidated financial statements.

Accounting Changes and Error Corrections [Abstract]
Implemented Accounting Pronouncements	NOTE 3. IMPLEMENTED ACCOUNTING PRONOUNCEMENTS Effective January 1, 2023, the Company adopted the ASU 2022-02, Financial Instruments—Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures, which eliminates the separate recognition and measurement guidance for troubled debt restructurings by creditors. In addition, the ASU requires disclosure of current-period gross write-offs by year of origination for financing receivables and net investments in leases within the scope of FASB ASC 326-20, Financial Instruments—Credit Losses—Measured at Amortized Cost. The adoption of this new guidance did not have a material impact on the Company's consolidated financial statements. Effective January 1, 2023, the Company adopted the ASU 2021-08, Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers, which requires an entity to recognize and measure contract assets and contract liabilities acquired in a business combination in accordance with ASC 606, Revenue from Contracts with Customers. Additionally, the ASU requires revenue contracts, including contract assets and liabilities, to be evaluated on the acquisition date and reported as if the contracts had originated with the acquirer, resulting in a measurement consistent with the recognition on the acquiree's financial statements. The adoption of this new guidance did not have a material impact on the Company's consolidated financial statements.

Business Combinations [Abstract]
Acquisitions	NOTE 4. ACQUISITIONS On February 1, 2023, the Company completed the acquisition of Vesta Housing Solutions Holdings, Inc. (“Vesta Modular”), a portfolio company of Kinderhook Industries, for $ 437.2 million cash consideration on the closing date, which included certain adjustments, including net working capital and certain qualified capital expenditures. In connection with the acquisition, the Company purchased a representation and warranty insurance policy to provide certain recourse in the event of breaches of representations and warranties of Vesta Modular and the seller of Vesta Modular under the stock purchase agreement. Vesta Modular is a leading provider of temporary and permanent modular space solutions serving customers between its modular leasing and modular construction divisions. The acquisition was accounted for as a purchase of a “business” in accordance with criteria in ASC 805, Business Combinations , using the purchase method of accounting. Under the purchase method of accounting, the total purchase price is assigned to tangible and identifiable intangible assets acquired and liabilities assumed based on their fair values on the closing date. The excess of the purchase price over those fair values is recorded as goodwill. During the quarter ended September 30, 2023, the purchase price allocation was revised resulting in a $ 12.8 million reduction in rental assets, $ 10.1 million reduction in deferred income taxes, a $ 0.4 million reduction in accounts payable and accrued liabilities, and a $ 3.9 million increase in the customer relationships intangible asset. The net impact of these revisions resulted in a $ 1.6 million reduction in Goodwill for Vesta Modular. The financial results of Vesta Modular were a part of the Mobile Modular segment since February 1, 2023, including $ 9.5 million of transaction costs. On March 1, 2023, the Company completed the purchase of assets of Jerald R. Brekke, Inc., DBA Brekke Storage ("Brekke Storage"), for a total purchase price of $ 16.4 million. Brekke Storage is a regional provider of portable storage solutions in the Colorado market. The acquisition expanded the Mobile Modular Portable Storage fleet by approximately 2,700 units and provided a new regional operation to serve the Colorado market. The acquisition was accounted for as a purchase of a “business” in accordance with criteria in ASC 805 using the purchase method of accounting. The financial results of Brekke Storage were a part of the Mobile Modular segment since March 1, 2023, including $ 0.2 million of transaction costs. On April 1, 2023, the Company completed the purchase of assets of Dixie Temporary Storage, LLC ("Dixie Storage"), for a purchase price of $ 4.9 million. Dixie Storage is a regional provider of portable storage solutions in the South Carolina market and is highly complementary to the Company's portable storage business segment. The acquisition expanded the Mobile Modular Portable Storage fleet by approximately 800 units and provided a new regional operation to serve the South Carolina market. The acquisition was accounted for as a purchase of a “business” in accordance with criteria in ASC 805, Business Combinations , using the purchase method of accounting. The financial results of Dixie Storage were a part of the Mobile Modular segment since April 1, 2023, including $ 0.1 million of transaction costs. On July 1, 2023, the Company completed the purchase of assets of Inland Leasing and Storage, LLC ("Inland Leasing"), for a purchase price of $ 3.8 million. Inland Leasing is a regional provider of portable storage solutions in the Colorado market and is highly complementary to the Company's portable storage business segment. The acquisition grew the Mobile Modular Portable Storage fleet by approximately 600 units, which will further support the Colorado market. The acquisition was accounted for as a purchase of "assets" in accordance with criteria in ASC 805 and the assessment of the fair value of the purchased assets was allocated primarily to rental equipment totaling $ 3.0 million and intangible assets totaling $ 0.7 million. Supplemental pro forma information has not been provided as the historical financial results of Inland Leasing were not significant. Incremental transaction costs associated with the asset purchase were not significant. The following tables summarize the preliminary purchase price allocations reflecting estimated fair values of assets acquired and liabilities assumed in the Vesta Modular, Brekke Storage and Dixie Storage business acquisitions, with excess amounts allocated to goodwill. The estimated fair values of the assets acquired and liabilities assumed at the acquisition date are determined based on preliminary valuations and analyses. Accordingly, the Company has made provisional estimates for the assets acquired and liabilities assumed. The valuation of intangible assets acquired is based on certain valuation assumptions including cash flow projections, discount rates, contributory asset charges and other valuation model inputs. The valuation of tangible long-lived assets acquired is dependent upon various analyses including an analysis of the condition and estimated remaining economic lives of the assets acquired.

The combined acquired goodwill of $ 217.4 million reflects the strategic fit of Vesta Modular, Brekke Storage and Dixie Storage with the Company’s modular and portable storage business operations. The Company amortizes the acquired customer relationships over their expected useful lives of 11 years for Vesta Modular, 8 years for Brekke Storage and 9 years for Dixie Storage. The expected useful life for the non-compete agreements is 5 years. The trade name intangible acquired from the Vesta Modular acquisition will be amortized over it's useful life of nine months . Goodwill is expected to have an indefinite life and will be subject to future impairment testing. The goodwill is deductible for tax purposes over 15 years. The following unaudited pro forma financial information shows the combined results of continuing operations of the Company and Vesta Modular as if the acquisition occurred as of the beginning of the periods presented. The pro forma results include the effects of the amortization of the purchased intangible assets and depreciation expense of acquired rental equipment valuation step up, interest expense on the debt incurred to finance the acquisitions. A pro forma adjustment has been made to reflect the income taxes that would have been recorded at the combined federal and state statutory rate of 26.5 % on the acquisitions’ combined net income.

Discontinued Operations and Disposal Groups [Abstract]
Discontinued Operations	NOTE 5. DISCONTINUED OPERATIONS On February 1, 2023, the Company completed the sale of Adler Tank Rentals, LLC to Ironclad Environmental Solutions, Inc. ("Ironclad"), a portfolio company of Kinderhook Industries, for a sale price of $ 268.0 million. The total transaction costs incurred from the divestiture was $ 8.9 million, with $ 6.7 million incurred during the nine months ended September 30, 2023, and $ 2.2 million incurred during the year ended December 31, 2022. The divestiture of the Company's Adler Tanks business represents the Company's strategic shift to concentrate its operations on its core modular and storage businesses. The sale price was subject to certain adjustments, including net working capital, certain qualified capital expenditures and certain transaction expenses to be borne by the Company. In connection with the sale, the Company entered into a number of ancillary agreements, including an escrow agreement associated with net working capital adjustments, a restricted covenant agreement, a transition services agreement, and a number of leases whereby Ironclad or one of its affiliates would be a lessee to certain properties owned by the Company that the Adler Tanks business would continue to utilize after the sale. These ancillary agreements do not provide for continued involvement by the Company in Adler Tanks. In accordance with ASC 205-20, Presentation of Financial Statements - Discontinued Operations and ASC 360 , Property, Plant and Equipment, the Company determined that the criteria for the presentation of discontinued operations and held-for-sale, respectively, were met during the first quarter of 2023. The following table presents the results of Adler Tanks as reported in income from discontinued operations within the condensed consolidated statements of income for the nine months ended September 30, 2023 and 2022: (dollar amounts in thousands) Nine Months Ended 2023 2022 Revenues Rental $ 6,520 $ 47,638 Rental related services 2,584 19,221 Rental operations 9,104 66,859 Sales 269 2,235 Other 65 1,082 Total revenues 9,438 70,176 Costs and Expenses Direct costs of rental operations: Depreciation of rental equipment 1,325 11,996 Rental related services 2,020 14,851 Other 1,270 9,783 Total direct costs of rental operations 4,614 36,630 Costs of sales 159 1,613 Total costs of revenues 4,773 38,243 Gross Profit Rental 3,926 25,859 Rental related services 564 4,370 Rental operations 4,490 30,229 Sales 110 622 Other 65 1,082 Total gross profit 4,665 31,933 Selling and administrative expenses 2,582 20,642 Income from operations 2,083 11,291 Interest expense allocation ( 374 ) ( 1,941 ) Income from discontinued operations before provision for income taxes 1,709 9,350 Provision for income taxes from discontinued operations 453 2,170 Income from discontinued operations $ 1,256 $ 7,180 Other Selected Information Adjusted EBITDA $ 3,682 $ 25,443 The following table presents the carrying value of the divested business' assets and liabilities as presented within assets and liabilities of discontinued operations on the condensed consolidated balance sheets as of December 31, 2022: December 31, (in thousands) 2022 Assets Accounts receivable, net of allowance for credit losses of $ 450 $ 20,086 Rental equipment, net 137,738 Property, plant and equipment, net 6,632 Prepaid expenses and other assets 191 Intangible assets, net 5,700 Goodwill 25,902 Total assets of discontinued operations $ 196,249 Liabilities Accounts payable and accrued liabilities $ 9,621 Deferred income taxes, net 43,550 Total liabilities of discontinued operations $ 53,171 For the nine months ended September 30, 2023 and 2022, significant operating and investing items related to Adler Tanks were as follows: September 30, September 30, (in thousands) 2023 2022 Operating activities of discontinued operations: Depreciation and amortization $ 1,457 $ 13,290 Gain on sale of used rental equipment ( 111 ) ( 478 ) Investing activities of discontinued operations: Proceeds from sales of used rental equipment 269 1,675 Purchases of rental equipment ( 25 ) ( 2,878 ) Purchases of property, plant and equipment ( 40 ) ( 88 ) The following table presents the reconciliation of income from discontinued operations to Adjusted EBITDA for the nine months ended September 30, 2023 and 2022: September 30, September 30, (in thousands) 2023 2022 Income from discontinued operations $ 1,256 $ 7,180 Provision for income taxes from discontinued operations 453 2,170 Interest expense 374 1,941 Depreciation and amortization 1,457 13,290 EBITDA 3,540 24,581 Share-based compensation 118 862 Transaction costs 24 — Adjusted EBITDA from discontinued operations $ 3,682 $ 25,443

Revenue Recognition

Revenue Recognition	9 Months Ended

Revenue from Contract with Customer [Abstract]
Revenue Recognition	NOTE 6. REVENUE RECOGNITION The Company’s accounting for revenues is governed by two accounting standards. The majority of the Company’s revenues are considered lease or lease related and are accounted for in accordance with Accounting Standards Codification (ASC) 842, Leases. Revenues determined to be non-lease related are accounted for in accordance with ASC 606, Revenue from Contracts with Customers. The Company accounts for revenues when approval and commitment from both parties have been obtained, the rights of the parties are identified, payment terms are identified, the contract has commercial substance and collectability of consideration is probable. The Company typically recognizes non-lease related revenues at a point in time because the customer does not simultaneously consume the benefits of the Company’s promised goods and services, or performance obligations, and obtains control when delivery and installation are complete. For contracts that have multiple performance obligations, the transaction price is allocated to each performance obligation in the contract based on the Company’s best estimate of the standalone selling prices of each distinct performance obligation in the contract. The standalone selling price is typically determined based upon the expected cost plus an estimated margin of each performance obligation. Revenue from contracts that satisfies the criteria for over time recognition is recognized as work is performed by using the ratio of costs incurred to estimated total contract costs for each contract. The majority of revenue for these contracts is derived from long-term projects which typically span multiple quarters . The timing of revenue recognition, billings, and cash collections results in billed contract receivables and contract assets on the Company's consolidated balance sheet. In the Company’s contracts, amounts are billed as work progresses in accordance with agreed-upon contractual terms, either at periodic intervals or upon achievement of contractual milestones. Billings can occur subsequent to revenue recognition, resulting in contract assets, or in advance, resulting in contract liabilities. These contract assets and liabilities are reported on the consolidated balance sheet on a contract-by-contract basis at the end of each reporting period. The contract liabilities included in Deferred income on the Company’s consolidated balance sheet totaled $ 34.2 million and $ 27.4 million at September 30, 2023 and December 31, 2022, respectively. Sales revenues totaling $ 8.0 million and $ 19.0 million were recognized during the three and nine months ended September 30, 2023, respectively, which were included in the contract liability balance at December 31, 2022. For certain modular building sales, the customer retains a small portion of the contract price until full completion of the contract, or revenue is recognizable prior to customer billing, which results in revenue earned in excess of billings. These unbilled contract assets are included in Accounts receivable on the Company’s consolidated balance sheet and totaled $ 1.2 million and $ 0.6 million at September 30, 2023 and December 31, 2022, respectively. The Company generally rents and sells to customers on 30 day payment terms. The Company does not typically offer variable payment terms or accept non-monetary consideration. Amounts billed and due from the Company’s customers are classified as Accounts receivable on the Company’s consolidated balance sheet. For certain sales of modular buildings, progress payments from the customer are received during the manufacturing of new equipment, or the preparation of used equipment. The advance payments are not considered a significant financing component because the payments are used to meet working capital needs during the contract and to protect the Company from the customer failing to adequately complete their obligations under the contract. Lease Revenues Rental revenues from operating leases are recognized on a straight-line basis over the term of the lease for all operating segments. Rental billings for periods extending beyond period end are recorded as deferred income and are recognized in the period earned. Rental related services revenues are primarily associated with relocatable modular buildings. For modular building leases, rental related services revenues for modifications, delivery, installation, dismantle and return delivery are lease related because the payments are considered minimum lease payments that are an integral part of the negotiated lease agreement with the customer. These revenues are recognized on a straight-line basis over the term of the lease. Certain leases are accounted for as finance leases. For these leases, sales revenue and the related accounts receivable are recognized upon delivery and installation of the equipment and the unearned interest is recognized over the lease term on a basis which results in a constant rate of return on the unrecovered lease investment. As of the nine months ended September 30, 2023, the Company’s future minimum lease payments to be received under non-cancelable finance leases were $ 4.1 million. Of the total investment in sales-type leases, non-current future minimum lease payments are expected to be $ 0.9 million in 2024, $ 0.7 million in 2025, and $ 0.2 million in 2026. The Company’s assessment of current expected losses on these receivables was not material and therefore no credit loss expense was provided as of the nine months ended September 30, 2023. Other revenues include interest income on finance leases and rental income on facility leases. In the three and nine months ended September 30, 2023, the Company’s lease revenues were $ 147.2 million and $ 424.6 million, respectively, consisting of $ 146.7 million and $ 422.5 million of operating lease revenues, respectively, and $ 0.5 million and $ 2.1 million of finance lease revenues, respectively. The Company has entered into finance leases to finance certain equipment sales to customers. The lease agreements have a bargain purchase option at the end of the lease term. For these leases, sales revenue and the related accounts receivable are recognized upon delivery and installation of the equipment and the unearned interest is recognized over the lease term on a straight-line basis, which results in a constant rate of return on the unrecovered lease investment. The Company’s finance lease revenues for the three and nine months ended September 30, 2023 include $ 0.4 million and $ 1.8 million of sales revenues, respectively, and $ 0.1 million and $ 0.3 million of interest income, respectively. Non-Lease Revenues Non-lease revenues are recognized in the period when control of the performance obligation is transferred, in an amount that reflects the consideration the Company expects to be entitled to receive in exchange for those goods or services. For portable storage containers and electronic test equipment, rental related services revenues for delivery and return delivery are considered non-lease revenues. Sales revenues are typically recognized at a point in time, which occurs upon the completion of delivery, installation and acceptance of the equipment by the customer. Accounting for non-lease revenues requires judgment in determining the point in time the customer gains control of the equipment and the appropriate accounting period to recognize revenue. Sales taxes charged to customers are reported on a net basis and are excluded from revenues and expenses. The following table disaggregates the Company’s revenues by lease (within the scope of ASC 842) and non-lease revenues (within the scope of ASC 606) and the underlying service provided for the three and nine months ended September 30, 2023 and 2022: (in thousands) Mobile TRS- Enviroplex Adler Consolidated Three Months Ended September 30, 2023 Leasing $ 113,955 $ 29,711 $ — $ — $ 143,666 Non-lease: Rental related services 18,251 664 — — 18,915 Sales 58,867 8,341 9,515 — 76,723 Other 3,809 393 — — 4,202 Total non-lease 80,927 9,398 9,515 — 99,840 Total revenues $ 194,882 $ 39,109 $ 9,515 $ — $ 243,506 2022 Leasing $ 86,428 $ 32,265 $ — $ 17,825 $ 136,518 Non-lease: Rental related services 10,427 684 — 7,069 18,180 Sales 28,922 5,291 9,978 976 45,167 Other 61 287 — 323 671 Total non-lease 39,410 6,262 9,978 8,368 64,018 Total revenues $ 125,838 $ 38,527 $ 9,978 $ 26,193 $ 200,536 Nine Months Ended September 30, 2023 Leasing $ 324,033 $ 90,388 $ — $ 6,612 $ 421,033 Non-lease: Rental related services 41,133 1,952 — 2,557 45,642 Sales 115,828 19,545 11,379 269 147,021 Other 4,807 1,189 — — 5,996 Total non-lease 161,768 22,686 11,379 2,826 198,659 Total revenues $ 485,801 $ 113,074 $ 11,379 $ 9,438 $ 619,692 2022 Leasing $ 240,693 $ 92,585 $ — $ 48,548 $ 381,826 Non-lease: Rental related services 22,960 1,919 — 18,890 43,769 Sales 64,113 14,031 15,545 2,234 95,923 Other 94 824 — 504 1,422 Total non-lease 87,167 16,774 15,545 21,628 141,114 Total revenues $ 327,860 $ 109,359 $ 15,545 $ 70,176 $ 522,940 Customer returns of rental equipment prior to the end of the rental contract term are typically billed a cancellation fee, which is recorded as rental revenue in the period billed. Sales of new relocatable modular buildings, portable storage containers, electronic test equipment and related accessories and liquid and solid containment tanks and boxes not manufactured by the Company are typically covered by warranties provided by the manufacturer of the products sold. The Company typically provides limited 90 -day warranties for certain sales of used rental equipment and one-year warranties on equipment manufactured by Enviroplex. Although the Company’s policy is to provide reserves for warranties when required for specific circumstances, warranty costs have not been significant to date. The Company’s incremental cost of obtaining lease contracts, which consists of salesperson commissions, are deferred and amortized over the initial lease term for modular leases. Incremental costs for obtaining a contract for all other operating segments are expensed in the period incurred because the lease term is typically less than 12 months. Other Income Other income consists of the net gain on sales of property, plant and equipment. These sales are generally recognized at a point in time, with contractually defined performance obligations that are typically transferred upon the closing date of the sale. These types of sales are infrequent in occurrence and reported on the condensed consolidated statements of income within the scope of ASC 610, Other Income. Proceeds to be received on the sale of property, plant and equipment are included in Accounts receivable on the Company's condensed consolidated balance sheets.

Earnings Per Share [Abstract]
Earnings Per Share	NOTE 7. EARNINGS PER SHARE Basic earnings per share (“EPS”) is computed as net income divided by the weighted-average number of shares of common stock outstanding for the period. Diluted EPS is computed assuming conversion of all potentially dilutive securities including the dilutive effect of stock options, unvested restricted stock awards and other potentially dilutive securities. The table below presents the weighted-average number of shares of common stock used to calculate basic and diluted earnings per share: Three Months Ended Nine Months Ended (in thousands) 2023 2022 2023 2022 Weighted-average number of shares of common stock for 24,487 24,379 24,461 24,342 Effect of potentially dilutive securities from equity-based 38 125 66 174 Weighted-average number of shares of common stock for 24,525 24,504 24,527 24,516 There were 1,800 anti-dilutive securities excluded from the computation of diluted earnings per share for the nine months ended September 30, 2023, and 7,315 anti-dilutive securities excluded from the computation of diluted earnings per share for the same period in 2022. The Company has in the past made purchases of shares of its common stock from time to time in over-the-counter market (NASDAQ) transactions, through privately negotiated, large block transactions and through a share repurchase plan, in accordance with Rule 10b5-1 of the Securities Exchange Act of 1934. In August 2015, the Company’s Board of Directors authorized the Company to repurchase up to 2,000,000 shares of the Company's outstanding common stock (the “Repurchase Plan”). The amount and time of the specific repurchases are subject to prevailing market conditions, applicable legal requirements and other factors, including management’s discretion. All shares repurchased by the Company are canceled and returned to the status of authorized but unissued shares of common stock. There can be no assurance that any authorized shares will be repurchased, and the Repurchase Plan may be modified, extended or terminated by the Company’s Board of Directors at any time. There were no shares repurchased during the three and nine months ended September 30, 2023 and 2022. As of September 30, 2023, 1,309,805 shares remained authorized for repurchase under the Repurchase Plan.

The Company also assesses potential impairment of its goodwill and intangible assets with indefinite lives on an annual basis regardless of whether there is evidence of impairment. If indicators of impairment were to be present in intangible assets used in operations and future discounted cash flows were not expected to be sufficient to recover the asset’s carrying amount, an impairment loss would be charged to expense in the period identified. The amount of an impairment loss that would be recognized is the excess of the asset’s carrying value over its fair value. Factors the Company considers important, which may cause impairment include, among others, significant changes in the manner of use of the acquired asset, negative industry or economic trends, and significant underperformance relative to historical or projected operating results. The Company last conducted a qualitative analysis of its goodwill and intangible assets in the fourth quarter 2022, with no indicators of impairment. In addition, no impairment triggering events occurred during the nine months ended September 30, 2023. Determining fair value of a reporting unit is judgmental and involves the use of significant estimates and assumptions. The Company bases its fair value estimates on assumptions that it believes are reasonable but are uncertain and subject to changes in market conditions. Intangible assets with finite useful lives are amortized over their respective useful lives. Amortization expense in the nine months ended September 30, 2023 and 2022, was $ 7.8 million and $ 4.4 million, respectively. Based on the carrying values at September 30, 2023 and assuming no subsequent impairment of the underlying assets, the amortization expense is expected to be $ 2.9 million for the remainder of fiscal year 2023, $ 10.3 million in 2024, $ 10.2 million in 2025, $ 9.8 million in 2026, $ 9.6 million in 2027 and $ 8.2 million in 2028.

Segment Reporting [Abstract]
Segment Reporting	NOTE 9. SEGMENT REPORTING The Company historically operated four reportable segments and divested its Adler Tanks business segment on February 1, 2023, see Note 5 to the consolidated financial statements for more information on the divestiture of Adler Tanks. The three reportable segments from continuing operations are (1) its modular building and portable storage container rental segment (“Mobile Modular”); (2) its electronic test equipment segment (“TRS-RenTelco”); and (3) its classroom manufacturing segment selling modular buildings used primarily as classrooms in California (“Enviroplex”). The operations of each of these segments are described in Part I – Item 1, “Business,” and the accounting policies of the segments are described in “Note 1 – Summary of Significant Accounting Policies” in the Company’s 2022 Annual Report. Management focuses on several key measures to evaluate and assess each segment’s performance, including rental revenue growth, gross profit and gross margins, income from operations, income before provision for income taxes and adjusted EBITDA. Excluding interest expense, allocations of revenue and expense not directly associated with one of these segments are generally allocated to Mobile Modular and TRS-RenTelco based on their pro-rata share of direct revenues.
