(a) Ending OEC — original equipment cost ("OEC") is the original equipment cost of units at a given point in time.

(b) Average OEC on rent — Average OEC on rent is calculated as the weighted-average OEC on rent during the stated period.

(c) Fleet utilization — total number of days the rental equipment was rented during a specified period of time divided by the total number of days available during the same period and weighted based on OEC.

(d) OEC on rent yield ("ORY") — a measure of return realized by our rental fleet during a 12-month period. ORY is calculated as rental revenue (excluding freight recovery and ancillary fees) during the stated period divided by the Average OEC on rent for the same period. For period less than 12 months, the ORY is adjusted to an annualized basis.

(e) Sales order backlog — purchase orders received for customized and stock equipment. Sales order backlog should not be considered an accurate measure of future net sales.

Full-year 2022 parts sales and service revenue improved 5.3% compared to 2021 pro forma revenue of $120.3 million.

In our ERS segment, rental revenue in the fourth quarter of 2022 was $123.4 million compared to $109.6 million in the fourth quarter of 2021, a 12.6% increase. Fleet utilization continued to increase, coming in at 86.3% compared to 83.7% in the fourth quarter of 2021. Gross profit in the segment in the fourth quarter of 2022 and 2021 was $77.8 million and $44.6 million, respectively, representing strong growth over the prior year period from both rentals and sales. Gross profit in the segment, excluding $39.8 million and $43.8 million of rental equipment depreciation in the fourth quarter of 2022 and 2021, respectively, was $117.7 million in the fourth quarter of 2022, compared to $88.4 million in the fourth quarter of 2021, representing strong growth over the prior year period from both rentals and sales. Gross profit from rentals, which excludes depreciation of rental equipment, improved to $96.7 million in the fourth quarter of 2022 compared to $82.7 million in the fourth quarter of 2021.

Revenue in our TES segment increased 39.6%, to $247.3 million in the fourth quarter of 2022, from $177.2 million in the fourth quarter of 2021, as an improvement in supply chain challenges allowed for greater order fulfillments. Gross profit improved by 89.7% to $44.4 million in the fourth quarter of 2022 compared to $23.4 million in the fourth quarter of 2021. In the fourth quarter, TES continued to see strength in product demand as sales order backlog grew by 6.3% to $754.1 million compared to the end of the third quarter of 2022, and is up 83.2% from the fourth quarter of 2021. On a sequential basis, supply chain headwinds lessened, with new equipment sales revenue increasing 42.3% in the fourth quarter of 2022 compared to the third quarter of 2022.

APS segment revenue experienced an increase of $3.2 million, or 9.3%, in the fourth quarter of 2022, to $37.5 million, as compared to $34.3 million in the fourth quarter of 2021. Growth in demand for parts, tools and accessories ("PTA") sales was offset by reduced tools and accessories rentals in the PTA division. Gross profit margin in the segment was negatively impacted by higher inventory costs due to shifts in product mix.

Net income was $30.9 million in the fourth quarter of 2022 compared to a net loss of $3.7 million for the fourth quarter of 2021. The improvement in net income is the result of gross profit expansion, offset by higher selling costs and interest expense on variable-rate debt and variable-rate floorplan liabilities.

Adjusted EBITDA for the fourth quarter of 2022 was $124.5 million, compared to $95.6 million for the fourth quarter of 2021. The increase in Adjusted EBITDA was largely driven by growth in rental demand and in new equipment sales, both of which contributed to margin expansion.

As of December 31, 2022, CTOS had cash and cash equivalents of $14.4 million, current and long-term debt of $1,361.7 million (net of deferred financing fees of $27.7 million), and current and long-term finance lease obligations of $5.0 million. Our net debt (non-GAAP measure as defined below) was $1,380.0 million as of December 31, 2022. Our net leverage ratio (non-GAAP measure), which is net debt divided by Adjusted EBITDA, was 3.5x as of December 31, 2022. Availability under the senior secured credit facility was $309.4 million as of December 31, 2022. For the twelve months ended December 31, 2022, we added net OEC of $92.4 million to our rental fleet. During the three months ended December 31, 2022, CTOS purchased approximately $8.0 million of its common stock under the previously announced stock repurchase program.

**2023 Outlook**

We are providing our full-year revenue and Adjusted EBITDA guidance for 2023 at this time. We believe ERS will continue to benefit from strong demand from our rental customers as well as for purchases of rental fleet units, particularly older equipment, in 2023. We also expect to further grow our rental fleet (based on net OEC) by mid- to high-single digits. Regarding TES, supply chain improvements, improved inventory levels exiting 2022, and record backlog levels should improve our ability to produce and deliver more units in 2023. "Our FY23 outlook reflects the ongoing strength of our end markets and the continued focus by our teams to

------

profitably grow our business. The outlook also reflects the moderated risks associated with some continued supply chain challenges, which we expect could persist through the fiscal year," said Ryan McMonagle, President and Chief Operating Officer of CTOS.

*1 - CTOS is not able to forecast net income on a forward-looking basis without unreasonable efforts due to the high variability and difficulty in predicting certain items that affect GAAP net income including, but not limited to, customer buyout requests on rentals with rental purchase options, income tax expense and changes in fair value of derivative financial instruments. Adjusted EBITDA should not be used to predict net income as the difference between the two measures is variable.*

**PRO FORMA FINANCIAL INFORMATION**

The unaudited pro forma combined financial information presented on the subsequent pages give effect to the Company's acquisition of Custom Truck LP, as if the Acquisition had occurred on January 1, 2020, and is presented to facilitate comparisons with our results following the Acquisition. This information has been prepared in accordance with Article 11 of Regulation S-X. Such unaudited pro forma combined financial information also uses the fair value of assets and liabilities, including the fair value of tax assets and liabilities, on April 1, 2021, the closing date of the Acquisition, and makes the following assumptions: (1) removes acquisition-related costs and charges that were recognized in the Company's consolidated financial statements in the three and twelve months ended December 31, 2021, and applies these costs and charges as if the transactions had occurred on January 1, 2020; (2) removes the loss on the extinguishment of debt that was recognized in the Company's consolidated financial statements in the three and twelve months ended December 31, 2021 and applies the charge to the three and twelve months ended December 31, 2020, as if the debt extinguishment giving rise to the loss had occurred on January 1, 2020; (3) adjusts for the impacts of purchase accounting in the three and twelve months ended December 31, 2021; (4) adjusts interest expense, including amortization of debt issuance costs, to reflect borrowings on the ABL Facility and issuance of the 2029 Secured Notes, as if the funds had been borrowed and the 2029 Secured Notes had been issued on January 1, 2020 and used to repay pre-acquisition debt; and, (5) adjusts for the income tax effect using a tax rate of 25%.

**NON-GAAP FINANCIAL AND PERFORMANCE MEASURES**

In our press release and schedules, and on the related conference call, we report certain financial measures that are not required by, or presented in accordance with, United States generally accepted accounting principles ("GAAP"). We utilize these financial measures to manage our business on a day-to-day basis and some of these measures are commonly used in our industry to evaluate performance. We believe these non-GAAP measures provide investors expanded insight to assess performance, in addition to the standard GAAP-based financial measures. The press release schedules reconcile the most directly comparable GAAP measure to each non-GAAP measure that we refer to. Although management evaluates and presents these non-GAAP measures for the reasons described herein, please be aware that these non-GAAP measures have limitations and should not be considered in isolation or as a substitute for revenue, operating income/loss, net income/loss, earnings/loss per share or any other comparable operating measure prescribed by GAAP. In addition, we may calculate and/or present these non-GAAP financial measures differently than measures with the same or similar names that other companies report, and as a result, the non-GAAP measures we report may not be comparable to those reported by others.

Custom Truck LP became a wholly owned subsidiary of the Company on April 1, 2021. The Company's consolidated financial statements prepared under GAAP include Custom Truck LP from April 1, 2021. Accordingly, the financial information presented under GAAP for the twelve months ended December 31, 2022 is not comparable to the financial information of the twelve months ended December 31, 2021. As a result, we have included information on a "pro forma combined basis" as further described below, which we believe provides for more meaningful year-over-year comparability.

**Adjusted EBITDA**. Adjusted EBITDA is a non-GAAP financial performance measure that we use to monitor our results of operations, to measure performance against debt covenants and performance relative to competitors. We believe Adjusted EBITDA is a useful performance measure because it allows for an effective evaluation of operating performance, without regard to financing methods or capital structures. We exclude the items identified in the reconciliations of net income (loss) to Adjusted EBITDA because these amounts are either non-recurring or can vary substantially within the industry depending upon accounting methods and book values of assets, including the method by which the assets were acquired, and capital structures. Adjusted EBITDA should not be considered as an alternative to, or more meaningful than, net income (loss) determined in accordance with GAAP. Certain items excluded from Adjusted EBITDA are significant components in understanding and assessing a company's financial performance, such as a company's cost of capital and tax structure, as well as the historical costs of depreciable assets, none of which are reflected in Adjusted EBITDA. Our presentation of Adjusted EBITDA should not be construed as an indication that results will be unaffected by the items excluded from Adjusted EBITDA. Our computation of Adjusted EBITDA may not be identical to other similarly titled measures of other companies.

We define Adjusted EBITDA as net income or loss before interest expense, income taxes, depreciation and amortization, share-based compensation, and other items that we do not view as indicative of ongoing performance. Our Adjusted EBITDA includes an adjustment to exclude the effects of purchase accounting adjustments when calculating the cost of inventory and used equipment sold. When inventory or equipment is purchased in connection with a business combination, the assets are revalued to their current fair values for accounting purposes. The consideration transferred (i.e., the purchase price) in a business combination is allocated to the fair values of the assets as of the acquisition date, with amortization or depreciation recorded thereafter following applicable accounting policies; however, this may not be indicative of the actual cost to acquire inventory or new equipment that is added to product inventory or the rental fleets apart from a business acquisition. Additionally, the pricing of rental contracts and equipment sales prices for equipment is based on OEC, and we measure a rate of return from rentals and sales using OEC. We also include an adjustment to remove the impact of accounting for certain of our rental contracts with customers containing a rental purchase option that are accounted for under GAAP as a sales-type lease. We include this adjustment because we believe continuing to reflect the transactions as an operating lease better reflects the economics of the transactions given our large portfolio of rental contracts. These, and other, adjustments to GAAP net income or loss that are applied to derive Adjusted EBITDA are specified by our senior secured credit agreements.

Although management evaluates and presents the Adjusted EBITDA non-GAAP measure for the reasons described herein, please be aware that this non-GAAP measure has limitations and should not be considered in isolation or as a substitute for revenue, operating income/loss, net income/loss, earnings/loss per share or any other comparable operating measure prescribed by GAAP. In addition, we may calculate and/or present this non-GAAP financial measure differently than measures with the same or similar names that other companies report, and, as a result, the non-GAAP measure we report may not be comparable to those reported by others.

We present Pro Forma Adjusted EBITDA as if the Acquisition had occurred on January 1, 2020. Refer to the reconciliation of pro forma combined net income (loss) to Pro Forma Adjusted EBITDA for the three and twelve months ended December 31, 2021 in this press release.

**Gross Profit and Rental Profit Excluding Rental Equipment Depreciation**. We present total gross profit excluding rental equipment depreciation as a non-GAAP financial performance measure. We also present rental gross profit that excludes rental equipment depreciation as a non-GAAP financial measure. These measures differ from the GAAP definitions of gross profit, as we do not include the impact of depreciation expense, which represents non-cash expense. We use these measures to evaluate operating margins and the effectiveness of the cost of our rental fleet.

**Net Debt.** We present the non-GAAP financial measure "net debt," which is total debt (the most comparable GAAP measure, calculated as current and long-term debt, excluding deferred financing fees, plus current and long-term finance lease obligations) minus cash and cash equivalents. We believe this non-GAAP measure is useful to investors to evaluate our financial position.

**Net Leverage Ratio.** Net leverage ratio is a non-GAAP financial performance measure used by management and we believe it provides useful information to investors because it is an important liquidity measure that reflects our ability to service debt. We define net leverage ratio as net debt divided by Adjusted EBITDA.

**Adjusted EBITDA** is defined as net income (loss) plus interest expense, provision for income taxes, depreciation and amortization, and further adjusted for non-cash purchase accounting impact, transaction and process improvement costs, including business integration expenses, share-based payments, the change in fair value of derivative instruments, sales-type lease adjustment, and other special charges that are not expected to recur. This non-GAAP measure is subject to certain limitations.

(1)&nbsp;&nbsp;&nbsp;&nbsp;Represents the non-cash impact of purchase accounting, net of accumulated depreciation, on the cost of equipment and inventory sold. The equipment and inventory acquired received a purchase accounting step-up in basis, which is a non-cash adjustment to the equipment cost pursuant to our credit agreement.

(2)&nbsp;&nbsp;&nbsp;&nbsp;Represents transaction and process improvement costs related to acquisitions of businesses, including post-acquisition integration costs, which are recognized within operating expenses in our Consolidated Statements of Comprehensive Net Income (Loss). These expenses are comprised of professional consultancy, legal, tax and accounting fees. Also included are expenses associated with the integration of acquired businesses. These expenses are presented as adjustments to net income (loss) pursuant to our ABL Credit Agreement.

(3)&nbsp;&nbsp;&nbsp;&nbsp;Loss on extinguishment of debt represents a special charge, which is not expected to recur. Such charges are adjustments pursuant to our credit agreement.

(4)&nbsp;&nbsp;&nbsp;&nbsp;Represents the adjustment for the impact of sales-type lease accounting for certain leases containing rental purchase options (or "RPOs"), as the application of sales-type lease accounting is not deemed to be representative of the ongoing cash flows of the underlying rental contracts. This adjustment is made pursuant to our credit agreement.
