These statements are based on certain factors and assumptions, including expected growth, market recovery, results of operations, performance and business prospects and opportunities regarding Dexterra, which Dexterra believes are reasonable as of the current date. While management considers these assumptions to be reasonable based on information currently available to Dexterra, they may prove to be incorrect. Forward-looking information is also subject to certain known and unknown risks, uncertainties and other factors that could cause Dexterra's actual results, performance or achievements to be materially different from any future results, performance or achievements expressed or implied by such forward-looking information, including, but not limited to: the ability to retain clients, renew existing contracts and obtain new business; an outbreak of contagious disease that could disrupt its business; the highly competitive nature of the industries in which Dexterra operates; reliance on suppliers and subcontractors; cost inflation; volatility of industry conditions could impact demand for its services; a reduction in the availability of credit could reduce demand for Dexterra's products and services; Dexterra's significant shareholder may substantially influence its direction and operations and its interests may not align with other shareholders; its significant shareholder's 49% ownership interest may impact the liquidity of the common shares; cash flow may not be sufficient to fund its ongoing activities at all times; loss of key personnel; the failure to receive or renew permits or security clearances; significant legal proceedings or regulatory proceedings/changes; environmental damage and liability is an operating risk in the industries in which Dexterra operates; climate changes could increase Dexterra's operating costs and reduce demand for its services; liabilities for failure to comply with public procurement laws and regulations; any deterioration in safety performance could result in a decline in the demand for its products and services; failure to realize anticipated benefits of acquisitions and dispositions; inability to develop and maintain relationships with Indigenous communities; the seasonality of Dexterra's business; inability to restore or replace critical capacity in a timely manner; reputational, competitive and financial risk related to cyber-attacks and breaches; failure to effectively identify and manage disruptive technology; economic downturns can reduce demand for Dexterra's services; its insurance program may not fully cover losses.

Non-GAAP Measures

Certain measures and ratios in this presentation do not have any standardized meaning as prescribed by GAAP and, therefore, are considered non-GAAP measures. Non-GAAP measures include "Adjusted EBITDA", calculated as earnings before interest, taxes, depreciation, amortization, equity investment depreciation, share based compensation, gain/loss on disposal of property, plant and equipment and non-recurring items; "Adjusted EBITDA as a percentage of revenue", calculated as Adjusted EBITDA divided by revenue; "Free Cash Flow", calculated as net cash flows from (used in) operating activities, less sustaining capital expenditures, lease payments and finance costs plus proceeds on the sale of property, plant and equipment; and "backlog" which is the total value of modular work that has not yet been completed that: (a) has a high certainty of being performed based on the existence of an executed contract or work order specifying job scope, value and timing; or (b) has been awarded to Dexterra Group, as evidenced by an executed letter of award or agreement, describing the general job scope, value and timing of such work, and where the finalization of a formal contract in respect of such work is reasonably assured and expects to be recognized in the next 12 months. Sustaining capital expenditures included in the definition of Free Cash Flow are replacement expenditures necessary to maintain existing business and/or leases necessary to maintain existing business. These measures and ratios provide investors with supplemental measures of Dexterra Group's operating performance and highlight trends in its core businesses that may not otherwise be apparent when relying solely on GAAP financial measures. Dexterra Group also believes that securities analysts, investors and other interested parties frequently use non-GAAP measures in the evaluation of issuers. Dexterra Group's management also uses non-GAAP measures in order to facilitate operating performance comparisons from period to period, to prepare annual operating budgets, and to determine components of management compensation.

These measures are regularly reviewed by the Chief Operating Decision Makers and provide investors with an alternative method for assessing the Corporation's operating results in a manner that is focused on the performance of
the Corporation's ongoing operations and to provide a consistent basis for comparison between periods. These measures should not be construed as alternatives to net earnings and total comprehensive income or operating cash
flows as determined in accordance with GAAP as indicators of the Corporation's performance. The method of calculating these measures may differ from other entities and accordingly, may not be comparable to measures used
by other entities. For a reconciliation of these non-GAAP measures to their nearest measure under GAAP please refer to " Reconciliation of non-GAAP measures" in the Management's Discussion and Analysis for the period ended
December 31, 2023.	2
