Notes

(1) All dollar amounts in this press release are in U.S. Dollars unless otherwise indicated.

(2) Use of Non-GAAP Financial Measures: In addition to reporting financial results in accordance with U.S. GAAP, the Company provides certain financial measures that are not in accordance with U.S. GAAP (Non-GAAP). These Non-GAAP financial measures have certain limitations in that they do not have a standardized meaning and thus the Company's definition may be different from similar Non-GAAP financial measures used by other companies and/or analysts and may differ from period to period. Thus it may be more difficult to compare the Company's financial performance to that of other companies. However, the Company's management compensates for these limitations by providing the relevant disclosure of the items excluded in the calculation of these Non-GAAP financial measures both in its reconciliation to the U.S. GAAP financial measures and its condensed consolidated financial statements, all of which should be considered when evaluating the Company's results.

The Company uses these Non-GAAP financial measures to supplement the information provided in its condensed consolidated financial statements, which are presented in accordance with U.S. GAAP. The presentation of Non-GAAP financial measures is not meant to be a substitute for financial measures presented in accordance with U.S. GAAP, but rather should be evaluated in conjunction with and as a supplement to such U.S. GAAP measures. OpenText strongly encourages investors to review its financial information in its entirety and not to rely on a single financial measure. The Company therefore believes that despite these limitations, it is appropriate to supplement the disclosure of the U.S. GAAP measures with certain Non-GAAP measures defined below.

Non-GAAP-based net income and Non-GAAP-based EPS, attributable to OpenText, are consistently calculated as GAAP-based net income (loss) or earnings (loss) per share, attributable to OpenText, on a diluted basis, excluding the effects of the amortization of acquired intangible assets, other income (expense), share-based compensation, and special charges (recoveries), all net of tax and any tax benefits/expense items unrelated to current period income, as further described in the tables below. Non-GAAP-based gross profit is the arithmetical sum of GAAP-based gross profit and the amortization of acquired technology-based intangible assets and share-based compensation within cost of sales. Non-GAAP-based gross margin is calculated as Non-GAAP-based gross profit expressed as a percentage of total revenue. Non-GAAP-based income from operations is calculated as GAAP-based income from operations, excluding the amortization of acquired intangible assets, special charges (recoveries), and share-based compensation expense.

Adjusted EBITDA is defined and calculated as GAAP-based net income (loss), attributable to OpenText, excluding interest income (expense), provision for (recovery of) income taxes, depreciation and amortization of acquired intangible assets, other income (expense), share-based compensation and special charges (recoveries). Adjusted EBITDA margin is calculated as adjusted EBITDA expressed as a percentage of total revenue.

Free cash flows is defined and calculated as GAAP-based cash flows provided by operating activities less capital expenditures.

The Company's management believes that the presentation of the above defined Non-GAAP financial measures provides useful information to investors because they portray the financial results of the Company before the impact of certain non-operational charges. The use of the term "non-operational charge" is defined for this purpose as an expense that does not impact the ongoing operating decisions taken by the Company's management. These items are excluded based upon the way the Company's management evaluates the performance of the Company's business for use in the Company's internal reports and are not excluded in the sense that they may be used under U.S. GAAP.

The Company does not acquire businesses on a predictable cycle, and therefore believes that the presentation of Non-GAAP measures, which in certain cases adjust for the impact of amortization of intangible assets and the related tax effects that are primarily related to acquisitions, will provide readers of financial statements with a more consistent basis for comparison across accounting periods and be more useful in helping readers understand the Company's operating results and underlying operational trends. Additionally, the Company has engaged in various restructuring activities over the past several years, primarily due to acquisitions and most recently in response to our return to office planning, that have resulted in costs associated with reductions in headcount, consolidation of leased facilities and related costs, all which are recorded under the Company's "Special charges (recoveries)" caption on the Condensed Consolidated Statements of Income. Each restructuring activity is a discrete event based on a unique set of business objectives or circumstances, and each differs in terms of its operational implementation, business impact and scope, and the size of each restructuring plan can vary significantly from period to period. Therefore, the Company believes that the exclusion of these special charges (recoveries) will also better aid readers of financial statements in the understanding and comparability of the Company's operating results and underlying operational trends.

In summary, the Company believes the provision of supplemental Non-GAAP measures allow investors to evaluate the operational and financial performance of the Company's core business using the same evaluation measures that management uses, and is therefore a useful indication of OpenText's performance or expected performance of future operations and facilitates period-to-period comparison of operating performance (although prior performance is not necessarily indicative of future performance). As a result, the Company considers it appropriate and reasonable to provide, in addition to U.S. GAAP measures, supplementary Non-GAAP financial measures that exclude certain items from the presentation of its financial results. Information reconciling certain forward-looking GAAP measures to non-GAAP measures related to outlook, estimates or business models, including A-EBITDA is not available without unreasonable effort due to high variability, complexity and uncertainty with respect to forecasting and quantifying certain amounts that are necessary for such reconciliations.

The following charts provide unaudited reconciliations of U.S. GAAP-based financial measures to Non-GAAP-based financial measures for the following periods presented.

(1) Adjustment relates to the exclusion of share-based compensation expense from our Non-GAAP-based operating expenses as this expense is excluded from our internal analysis of operating results. (2) Adjustment relates to the exclusion of amortization expense from our Non-GAAP-based operating expenses as the timing and frequency of amortization expense is dependent on our acquisitions and is hence excluded from our internal analysis of operating results. (3) GAAP-based and Non-GAAP-based gross profit stated in dollars and gross margin stated as a percentage of total revenue. (4) Adjustment relates to the exclusion of special charges (recoveries) from our Non-GAAP-based operating expenses as special charges (recoveries) are generally incurred in the periods relevant to an acquisition and include certain charges or recoveries that are not indicative or related to continuing operations and are therefore excluded from our internal analysis of operating results. (5) GAAP-based and Non-GAAP-based income from operations stated in dollars. (6) Adjustment relates to the exclusion of other income (expense) from our Non-GAAP-based operating expenses as other income (expense) generally relates to the transactional impact of foreign exchange and is generally not indicative or related to continuing operations and is therefore excluded from our internal analysis of operating results. Other income (expense) also includes our share of income (losses) from our holdings in investments as a limited partner. We do not actively trade equity securities in these privately held companies nor do we plan our ongoing operations based around any anticipated fundings or distributions from these investments. We exclude gains and losses on these investments as we do not believe they are reflective of our ongoing business and operating results. Other income (expense) also includes unrealized and realized gains (losses) on our derivatives which are not designated as hedges. We exclude gains and losses on these derivatives as we do not believe they are reflective of our ongoing business and operating results. (7) Adjustment relates to differences between the GAAP-based tax provision rate of approximately 17% and a Non-GAAP-based tax rate of approximately 24%; these rate differences are due to the income tax effects of items that are excluded for the purpose of calculating Non-GAAP-based net income. Such excluded items include amortization, share-based compensation, special charges (recoveries) and other income (expense), net. Also excluded are tax benefits/expense items unrelated to current period income such as changes in reserves for tax uncertainties and valuation allowance reserves and "book to return" adjustments for tax return filings and tax assessments. Beginning in Fiscal 2025, net tax benefits arising from the internal reorganization that occurred in Fiscal 2017 have been fully utilized and are no longer included. In arriving at our Non-GAAP-based tax rate of approximately 24%, we analyzed the individual adjusted expenses and took into consideration the impact of statutory tax rates from local jurisdictions incurring the expense.

(1) Adjustment relates to the exclusion of share-based compensation expense from our Non-GAAP-based operating expenses as this expense is excluded from our internal analysis of operating results. (2) Adjustment relates to the exclusion of amortization expense from our Non-GAAP-based operating expenses as the timing and frequency of amortization expense is dependent on our acquisitions and is hence excluded from our internal analysis of operating results. (3) GAAP-based and Non-GAAP-based gross profit stated in dollars and gross margin stated as a percentage of total revenue. (4) Adjustment relates to the exclusion of special charges (recoveries) from our Non-GAAP-based operating expenses as special charges (recoveries) are generally incurred in the periods relevant to an acquisition and include certain charges or recoveries that are not indicative or related to continuing operations and are therefore excluded from our internal analysis of operating results. (5) GAAP-based and Non-GAAP-based income from operations stated in dollars. (6) Adjustment relates to the exclusion of other income (expense) from our Non-GAAP-based operating expenses as other income (expense) generally relates to the transactional impact of foreign exchange and is generally not indicative or related to continuing operations and is therefore excluded from our internal analysis of operating results. Other income (expense) also includes our share of income (losses) from our holdings in investments as a limited partner. We do not actively trade equity securities in these privately held companies nor do we plan our ongoing operations based around any anticipated fundings or distributions from these investments. We exclude gains and losses on these investments as we do not believe they are reflective of our ongoing business and operating results. Other income (expense) also includes unrealized and realized gains (losses) on our derivatives which are not designated as hedges. We exclude gains and losses on these derivatives as we do not believe they are reflective of our ongoing business and operating results. (7) Adjustment relates to differences between the GAAP-based tax provision rate of approximately 22% and a Non-GAAP-based tax rate of approximately 24%; these rate differences are due to the income tax effects of items that are excluded for the purpose of calculating Non-GAAP-based net income. Such excluded items include amortization, share-based compensation, special charges (recoveries) and other income (expense), net. Also excluded are tax benefits/expense items unrelated to current period income such as changes in reserves for tax uncertainties and valuation allowance reserves and "book to return" adjustments for tax return filings and tax assessments. Beginning in Fiscal 2025, net tax benefits arising from the internal reorganization that occurred in Fiscal 2017 have been fully utilized and are no longer included. In arriving at our Non-GAAP-based tax rate of approximately 24%, we analyzed the individual adjusted expenses and took into consideration the impact of statutory tax rates from local jurisdictions incurring the expense.
