Accounting Changes and Error Corrections [Abstract]
Implemented Accounting Pronouncements	NOTE 3. IMPLEMENTED ACCOUNTING PRONOUNCEMENTS Effective January 1, 2024, the Company adopted the 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 adoption of this new guidance did not have a material impact on the Company's consolidated financial statements.

Acquisitions

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 was 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 Accounting Standards Codification ("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. The financial results of Vesta Modular were a part of the Mobile Modular segment since February 1, 2023, including $ 7.7 million of acquisition related transaction costs. On March 1, 2023, the Company completed the acquisition of Jerald R. Brekke, Inc., DBA Brekke Storage ("Brekke Storage"), for a total purchase price of $ 16.4 million. Brekke Storage was a regional provider of portable storage solutions in the Colorado market. The acquisition expanded the 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 Portable Storage segment since March 1, 2023, including $ 0.2 million of transaction costs. On April 1, 2023, the Company completed the acquisition of Dixie Temporary Storage, LLC ("Dixie Storage"), for a purchase price of $ 4.9 million. Dixie Storage was 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 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 Dixie Storage were a part of the Portable Storage 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 was 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 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 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. Vesta Modular: (dollar amounts in thousands) Rental equipment $ 212,639 Intangible assets: Goodwill 211,178 Customer relationships 29,900 Non-compete 7,100 Trade name 800 Cash 11 Accounts receivable 22,666 Property, plant and equipment 1,437 Prepaid expenses and other assets 3,550 Accounts payable and accrued liabilities ( 26,202 ) Deferred income ( 14,273 ) Deferred income taxes ( 11,596 ) Total purchase price $ 437,210 Brekke Storage: (dollar amounts in thousands) Rental equipment $ 10,798 Intangible assets: Goodwill 4,083 Customer relationships 949 Non-compete 59 Property, plant and equipment 875 Deferred income ( 382 ) Total purchase price $ 16,382 Dixie Storage: (dollar amounts in thousands) Rental equipment $ 2,758 Intangible assets: Goodwill 1,555 Customer relationships 259 Non-compete 22 Property, plant and equipment 318 Deferred income ( 161 ) Total purchase price $ 4,751 The value assigned to identifiable intangible assets was determined based on discounted estimated future cash flows associated with such assets to their present value. The combined acquired goodwill of $ 216.8 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 table reports the actual results of the Company for the three months ended March 31, 2024, and the unaudited pro forma financial information for the three months ended March 31, 2023. The 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 period 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. The pro forma results for the three months ended March 31, 2023, have been adjusted to include transaction related costs. This pro forma data is presented for informational purposes only and does not purport to be indicative of the results of the future operations or the results that would have occurred had the acquisitions taken place in the periods noted below: (Unaudited) Three months ended March 31, (dollar amounts in thousands, except for per share amounts) 2024 2023 (Actual) (Pro Forma) Pro-forma total revenues $ 187,827 $ 171,361 Pro-forma net income $ 22,848 $ 11,222 Pro-forma basic earnings per share $ 0.93 $ 0.46 Pro-forma diluted earnings per share $ 0.93 $ 0.46 Vesta Modular Actual total revenues $ 17,584 Actual net income $ 3,679 Actual basic earnings per share $ 0.15 Actual diluted earnings per share $ 0.15

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 were $ 8.8 million, with $ 6.7 million and $ 2.1 million incurred during the years ended December 31, 2023 and 2022, respectively. 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.

Revenue Recognition

Revenue Recognition	3 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 842, Leases (Topic 842). Revenues determined to be non-lease related are accounted for in accordance with ASC 606, Revenue from Contracts with Customers (Topic 606). 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 satisfy the criteria for over time recognition are 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 Sheets. 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 Sheets 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 Sheets totaled $ 54.3 million and $ 40.7 million at March 31, 2024 and December 31, 2023, respectively. Sales revenues totaling $ 9.7 million were recognized during the three months ended March 31, 2024, which were included in the contract liability balance at December 31, 2023. 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 Sheets and totaled $ 8.4 million and $ 8.7 million at March 31, 2024 and December 31, 2023, respectively. The Company did not recognize any material contract asset impairments during the periods ended March 31, 2024 and December 31, 2023, respectively. The Company's uncompleted contracts with customers which meet the criteria for over-time revenue recognition have unsatisfied or partially satisfied performance obligations. As of March 31, 2024, approximately $ 50.3 million of revenue is expected to be recognized for unsatisfied or partially satisfied obligations. The Company expects to recognize revenue for approximately one half of these unsatisfied or partially satisfied performance obligations over the next 12 months, with the remaining balance recognized thereafter. For the three months ended March 31, 2024, approximately $ 40.2 million of revenue was recognized for sales and non-lease services transferred at a point in time and approximately $ 7.5 million of revenue was recognized for sales and non-lease services transferred over time. 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 three months ended March 31, 2024, the Company’s future minimum lease payments to be received under non-cancelable finance leases were $ 3.2 million. Of the total investment in sales-type leases, non-current future minimum lease payments are expected to be $ 0.8 million in 2025, $ 0.4 million in 2026, and $ 0.1 million in 2027. 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 three months ended March 31, 2024. Other revenues include interest income on finance leases and rental income on facility leases. In the three months ended March 31, 2024, the Company’s lease revenues were $ 140.2 million, consisting of $ 139.8 million of operating lease revenues and $ 0.4 million of finance lease revenues. 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 months ended March 31, 2024 include $ 0.3 million of sales revenues and $ 0.1 million of interest income. 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 Topic 842) and non-lease revenues (within the scope of Topic 606) and the underlying service provided for the three months ended March 31, 2024 and 2023: (in thousands) Mobile Portable Storage TRS- Enviroplex Consolidated Three Months Ended March 31, 2024 Leasing $ 94,890 $ 19,030 $ 26,245 $ — $ 140,165 Non-lease: Rental related services 4,272 4,391 623 — 9,286 Sales 25,326 1,212 6,539 1,719 34,796 Other 3,097 127 356 — 3,580 Total non-lease 32,695 5,730 7,518 1,719 47,662 Total revenues $ 127,585 $ 24,760 $ 33,763 $ 1,719 $ 187,827 2023 Leasing $ 82,003 $ 17,656 $ 30,322 $ — $ 129,981 Non-lease: Rental related services 4,550 4,424 726 — 9,700 Sales 16,967 638 4,623 941 23,169 Other 407 12 449 — 868 Total non-lease 21,924 5,074 5,798 941 33,737 Total revenues $ 103,927 $ 22,730 $ 36,120 $ 941 $ 163,718 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 and electronic test equipment 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, net Other income, net 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 from 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 (in thousands) 2024 2023 Weighted-average number of shares of common stock for 24,513 24,416 Effect of potentially dilutive securities from equity-based 51 126 Weighted-average number of shares of common stock for 24,564 24,542 There were 73,190 and 96,241 anti-dilutive securities excluded from the computation of diluted earnings per share for the three months ended March 31, 2024 and 2023, respectively. 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 months ended March 31, 2024 and 2023. As of March 31, 2024, 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 2023, with no indicators of impairment. In addition, no impairment triggering events occurred during the three months ended March 31, 2024, and there were no changes to the carrying value of goodwill during this period. 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 three months ended March 31, 2024 and 2023, was $ 2.6 million and $ 2.3 million, respectively. Based on the carrying values at March 31, 2024 and assuming no subsequent impairment of the underlying assets, the amortization expense is expected to be $ 7.7 million for the remainder of fiscal year 2024, $ 10.2 million in 2025, $ 9.8 million in 2026, $ 9.6 million in 2027, $ 8.2 million in 2028 and $ 4.7 million in 2029.

Segment Reporting

Segment Reporting [Abstract]
Segment Reporting	NOTE 10. SEGMENT REPORTING During the quarter ended December 31, 2023, the Company determined that its Portable Storage business segment met the criteria for separate recognition as defined in the Accounting Standards Codification ("ASC") Topic 280, Segment Reporting. The guidance under this topic requires a public business entity to evaluate both quantitative and qualitative thresholds to determine the significance of a business segment and whether the separate reporting of a business segment enhances the users' understanding of the reporting entity's performance, future net cash flows and judgments. The Company evaluated the guidance within Topic 280 and made its determination to separately report the Portable Storage segment primarily due to the Company's continued growth in container fleet purchases and related increased revenues and improved profitability performance when compared to previously reported periods. In addition to this determination, the Company also divested its Adler Tanks business segment during the year ended December 31, 2023. Additional information regarding the divestiture of Adler Tanks can be found in Note 5 of the condensed consolidated financial statements. At March 31, 2024, the Company was comprised of four reportable segments: (1) its modular building segment (“Mobile Modular”); (2) its portable storage container segment ("Portable Storage"); (3) its electronic test equipment segment (“TRS-RenTelco”); and (4) 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 2023 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 and income before provision for income taxes. Excluding interest expense, allocations of revenue and expense not directly associated with one of these segments are generally allocated to Mobile Modular, Portable Storage and TRS-RenTelco based on their pro-rata share of direct revenues. Interest expense is allocated amongst Mobile Modular, Portable Storage and TRS-RenTelco based on their pro-rata share of average rental equipment at cost, intangible assets, accounts receivable, deferred income and customer security deposits. The Company does not report total assets by business segment. Summarized financial information for the three months ended March 31, 2024 and 2023 for the Company’s reportable segments are shown in the following table: (dollar amounts in thousands) Mobile Portable Storage TRS- Enviroplex 1 Consolidated Three Months Ended March 31, 2024 Rental revenues $ 76,496 $ 18,407 $ 25,429 $ — $ 120,332 Rental related services revenues 24,133 4,723 724 — 29,580 Sales and other revenues 26,956 1,630 7,610 1,719 37,915 Total revenues 127,585 24,760 33,763 1,719 187,827 Depreciation of rental equipment 9,874 965 11,527 — 22,366 Gross profit 61,845 17,103 13,875 445 93,268 Selling and administrative expenses 40,087 9,010 8,918 1,803 59,818 Other income ( 6,220 ) ( 1,319 ) ( 1,742 ) — ( 9,281 ) Income (loss) from operations 27,978 9,412 6,699 ( 1,358 ) 42,731 Interest (expense) income allocation ( 9,799 ) ( 1,420 ) ( 2,062 ) 577 ( 12,704 ) Income (loss) before provision for income taxes 18,179 7,992 4,505 ( 781 ) 29,895 Rental equipment acquisitions 59,263 5,128 3,393 — 67,784 Accounts receivable, net (period end) 166,382 14,117 22,637 8,814 211,950 Rental equipment, at cost (period end) 1,345,919 240,517 370,641 — 1,957,077 Rental equipment, net book value (period end) 1,013,965 220,811 133,766 — 1,368,542 Utilization (period end) 2 78.5 % 68.8 % 56.8 % Average utilization 2 78.7 % 69.8 % 56.5 % 2023 Rental revenues $ 64,056 $ 17,057 $ 29,134 $ — $ 110,247 Rental related services revenues 21,534 4,718 880 — 27,132 Sales and other revenues 18,337 955 6,106 941 26,339 Total revenues 103,927 22,730 36,120 941 163,718 Depreciation of rental equipment 8,657 787 12,389 — 21,833 Gross profit 46,171 15,451 15,620 125 77,367 Selling and administrative expenses 38,456 8,058 9,451 1,533 57,498 Other income — — — — — Income (loss) from operations 7,715 7,393 6,169 ( 1,408 ) 19,869 Interest (expense) income allocation ( 5,387 ) ( 884 ) ( 1,742 ) 549 ( 7,464 ) Income (loss) before provision for income taxes 2,328 6,509 4,653 ( 859 ) 12,631 Rental equipment acquisitions 54,448 7,651 10,112 — 72,211 Accounts receivable, net (period end) 135,104 13,776 24,493 3,633 177,006 Rental equipment, at cost (period end) 1,200,869 211,215 401,801 — 1,813,885 Rental equipment, net book value (period end) 901,090 195,074 171,104 — 1,267,268 Utilization (period end) 2 79.5 % 79.8 % 59.0 % Average utilization 2 79.4 % 80.8 % 59.2 % 1. Gross Enviroplex sales revenues were $ 1,719 and $ 941 for the three months ended March 31, 2024 and 2023, respectively. There were no inter-segment sales to Mobile Modular in the three months ended March 31, 2024 and 2023, which required elimination in consolidation. 2. Utilization is calculated each month by dividing the cost of rental equipment on rent by the total cost of rental equipment, excluding accessory equipment, and new equipment inventory. The Average utilization for the period is calculated using the average costs of rental equipment. No single customer accounted for more than 10% of total revenues for the three months ended March 31, 2024 and 2023. Revenues from foreign country customers accounted for 2 % and 3 % of the Company’s total revenues for the same periods, respectively. NOTE 11. SUBSEQUENT EVENT On April 23, 2024, the Company entered into a first incremental facility amendment with Bank of America, N.A., as Administrative Agent and the first incremental lender (“BoA”) and the guarantors named therein (the “First Incremental Amendment”).

Summary of Preliminary Purchase Price Allocations Reflecting Estimated Fair Values of Assets Acquired and Liabilities Assumed	The following tables summarize the 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.
