ATS Disclaimer Non-IFRS and Other Financial Measures: Throughout this presentation management uses certain non-IFRS financial measures, non-IFRS ratios and supplementary financial measures to evaluate the performance of the Company. The terms "EBITDA", "organic revenue", "adjusted EBITDA", and "free cash flow", are non-IFRS financial measures, "adjusted earnings from operations margin" (or "adjusted EBIT margin"), "adjusted EBITDA margin", "organic revenue growth", "non-cash working capital as a percentage of revenues", and "net debt to adjusted EBITDA" are non-IFRS ratios, and "operating margin (or EBIT Margin)", "Order Bookings", "Order Backlog", "reoccurring revenues", "custom integration revenues", "equipment / products revenues", and "service including spare parts revenues" are supplementary financial measures, all of which do not have any standardized meaning prescribed within International Financial Reporting Standards ("IFRS") and therefore may not be comparable to similar measures presented by other companies. Such measures should not be considered in isolation or as a substitute for measures of performance prepared in accordance with IFRS. In addition, management uses "earnings from operations", which is an additional IFRS measure, to evaluate the performance of the Company. Earnings from operations is presented on the Company's consolidated statements of income as net income excluding income tax expense and net finance costs. Operating margin (or EBIT Margin) is an expression of the Company's earnings from operations as a percentage of revenues. Adjusted earnings from operations margin (or adjusted EBIT margin) is an expression of the Company's earnings from operations before items excluded from management's internal analysis of operating results, such as amortization expense of acquisition-related intangible assets, acquisition-related transaction and integration costs, restructuring charges, the mark-to-market adjustment on stock-based compensation and certain other adjustments which would be non-recurring in nature ("adjustment items") as a percentage of revenues. EBITDA is defined as earnings from operations excluding depreciation and amortization. Adjusted EBITDA is defined as EBITDA before adjustment items. Adjusted EBITDA margin is an expression of the Company's adjusted EBITDA as a percentage of revenues. Organic revenue is defined as revenues in the stated period excluding revenues from acquired companies for which the acquired company was not a part of the consolidated group in the comparable prior period. Organic revenue growth compares the stated period organic revenue with the reported revenue of the comparable period. Non-cash working capital as a percentage of revenues is defined as the sum of accounts receivable, contract assets, inventories, deposits, prepaids and other assets, less accounts payable, accrued liabilities, provisions and contract liabilities divided by the trailing two fiscal quarter revenues annualized. Reoccurring revenue for ATS is defined as revenue from ancillary products and services associated with equipment sales and revenue from customers who purchase non-customized ATS products at regular intervals. Custom integration revenues are defined as revenues from end-to-end manufacturing solutions customized to customer needs. Equipment / products revenues are defined as revenues from modular or standardized equipment and other products. Services including spare parts revenues are defined as revenues from consulting, digital and other services, including aftermarket services and spares. Free cash flow is defined as cash provided by operating activities less property, plant and equipment and intangible asset expenditures. Net debt to adjusted EBITDA is the ratio of the net debt of the Company (cash and cash equivalents less bank indebtedness, long-term debt, and lease liabilities) to adjusted EBITDA. Order Bookings represent new orders for the supply of automation systems, services and products that management believes are firm. Order Backlog is the estimated unearned portion of revenues on customer contracts that are in process and have not been completed at the specified date. Following amendments to ATS' Restricted Stock Unit ("RSU") Plan in 2022 to provide for settlement in shares purchased in the open market and the creation of the employee benefit trust to facilitate such settlement, ATS began to account for equity- settled RSUs using the equity method of accounting. However, prior RSU grants which will be cash-settled and deferred stock unit ("DSU") grants which will be cash-settled are accounted for as described in the Company's annual consolidated financial statements and have significant volatility period over period based on the fluctuating price of ATS' common shares. As a result, certain Non-IFRS Financial Measures used in this presentation (adjusted EBITDA) were revised from previously disclosed values to exclude the impact on stock-based compensation expense of the revaluation of DSUS and RSUs resulting specifically from the change in market price of the Company's shares between periods. Management believes that this adjustment provides further insight into the Company's performance, as share price volatility drives variability in the Company's stock-based compensation expense. Earnings from operations, operating margin, adjusted earnings from operations margin, EBITDA, adjusted EBITDA and adjusted EBITDA margin are used by the Company to evaluate the performance of its operations. Management believes that earnings from operations is an important indicator in measuring the performance of the Company's operations on a pre-tax basis and without consideration as to how the Company finances its operations. Management believes that organic revenue and organic revenue growth, when considered with IFRS measures, allow the Company to better measure the Company's performance and evaluate long-term performance trends. Organic revenue growth also facilitates easier comparisons of the Company's performance with prior and future periods and relative comparisons to its peers. Management believes that EBITDA and adjusted EBITDA are important indicators of the Company's ability to generate operating cash flows to fund continued investment in its operations. Management believes that adjusted EBITDA is an important measure to increase comparability of performance between periods. The adjustment items used by management to arrive at these metrics are not considered to be indicative of the business' ongoing operating performance. Reoccurring revenues, custom integration revenues, equipment / products revenues and service including spare parts revenues are used by the Company to understand the revenue portfolio of the Company. Free cash flow is used by the Company to measure cash flow from operations after investment in property, plant and equipment and intangible assets. Management uses the measure "non-cash working capital as a percentage of revenues" to assess overall liquidity. Management uses net debt to adjusted EBITDA as a measurement of leverage of the Company. Order Bookings provide an indication of the Company's ability to secure new orders for work during a specified period, while Order Backlog provides a measure of the value of Order Bookings that have not been completed at a specified point in time. Both Order Bookings and Order Backlog are indicators of future revenues that the Company expects to generate based on contracts that management believes to be firm. Management believes that ATS shareholders and potential investors in ATS use these additional IFRS measures and non-IFRS financial measures in making investment decisions and measuring operational results.
