As of December 31, 2023, OpenText reported the net assets of AMC and OT Connectivity as assets and liabilities held for sale in accordance with Financial Accounting Standards Board Accounting Standards Codification 360, Property, Plant and Equipment (“ASC 360”).

The unaudited pro forma condensed consolidated financial information has been prepared in accordance with Regulation S-X Article 11, Pro Forma Financial Information. The unaudited pro forma condensed consolidated financial information is prepared in accordance with generally accepted accounting principles in the United States (U.S. GAAP) on a carve-out basis using the Company’s historical consolidated financial statements and reflects certain assumptions and adjustments that management believes are reasonable under the circumstances and given the information available at this time.

The unaudited pro forma condensed consolidated financial information has been derived from the Company’s historical consolidated financial statements and reflects certain assumptions and adjustments that management believes are reasonable under the circumstances and given the information available at this time. This unaudited pro forma condensed consolidated financial information reflects adjustments that, in the opinion of management, are necessary to state fairly the pro forma financial position and results of operations as of and for the periods indicated. AMC results of operations were consolidated with those of the Company’s beginning on February 1, 2023. As such, the Company’s historical results of operations for the year ended June 30, 2023 included five months of AMC results. The unaudited pro forma condensed consolidated financial information presented herein does not include any adjustments for allocations of shared costs identified by management.

The accounting policies under U.S. GAAP that were used in the preparation of the unaudited pro forma condensed consolidated financial information are those set forth in OpenText’s financial statements included in its Annual Report on Form 10-K for the year ended June 30, 2023 and in its Quarterly Report on Form 10-Q for the fiscal quarter ended December 31, 2023.

(a)Represents the Company’s historical condensed consolidated statements of income for the six months ended December 31, 2023 and for the year ended June 30, 2023 and historical condensed consolidated balance sheet as of December 31, 2023, prior to any pro forma adjustments described below.

(b)Represents the results of operations of AMC Group for the six months ended December 31, 2023 and for the year ended June 30, 2023 and historical assets and liabilities as of December 31, 2023.

(c)Adjustment reflects the increase in cash and cash equivalents of $232.6 million resulting from the cash consideration received based upon the $2.275 billion purchase price, before taxes, fees and other adjustments and the utilization of proceeds to prepay long-term debt by the Company. See footnote 3 (d). The remaining cash proceeds of $232.6 million will be primarily utilized to settle income tax liabilities and transaction related expenses resulting from the divestiture. See footnote 3 (j).

(d)Adjustment reflects the estimated prepayment of the outstanding principal balances of the Company’s Term Loan B and the Acquisition Term Loan of $2.0 billion, net of unamortized deferred financing costs of $47.2 million, which are charged to Other income (expense), net upon repayment. See footnote 3 (h).

(e)Subsequent to December 31, 2023 and through the date of the Transaction, the Company has incurred additional non-recurring costs of approximately $33.7 million to complete the Transaction. These costs primarily relate to accounting, legal and other advisory fees associated with separation activities.

(f)In connection with the Transaction, OpenText and Rocket entered into a Transition Services Agreement whereby OpenText will provide certain post-closing services on a transitional basis. As management expects that the transition service costs and offsetting reimbursements will be primarily recorded in general and administrative expense, a pro forma adjustment reducing general and administrative expense by up to $32.2 million and $64.4 million for the six months ended December 31, 2023 and for the year ended June 30, 2023, respectively, is reflected for this contractual arrangement based on management’s reasonable estimate of the services and duration of service periods to be provided under the Transition Services Agreement. Actual reimbursement amounts and financial statement line item impacts of the above reimbursements may differ from the general and administrative expense adjustment presentation in the unaudited pro forma condensed consolidated financial information.

(g)Adjustment reflects the gain on disposition of $521.3 million before taxes, fees and other adjustments, based on the net asset value of the AMC Group as of December 31, 2023. The final purchase price will be determined subsequent to the closing of the Transaction to reflect adjustments in accordance with the purchase agreement, including customary net working capital adjustments and final gain on disposition will be calculated based on the net asset value as of the closing date. The actual gain on disposition may be different from the gain recorded herein.

(h)Reflects the debt extinguishment loss of $47.2 million related to the repayment of debt as described in 3 (d) above for the year ended June 30, 2023.

(i)Reflects the reduction in interest expense of $81.9 million and $95.1 million to give effect to the estimated repayment of debt described in 3 (d) above for the six months ended December 31, 2023 and for the year ended June 30, 2023, respectively.

(j)The pro forma adjustments to the historical condensed consolidated balance sheet reflect the tax effects expected related to the Transaction and the removal of certain deferred income tax liabilities in connection with the gain on disposition. The pro forma adjustments to the historical condensed consolidated statements of income reflect the tax effects of the transaction accounting pro forma adjustments at the expected applicable statutory tax rates and the expected tax effects on the gain on disposition. Income tax adjustments are anticipated to be settled within twelve months of the close of the Transaction, using the remaining cash consideration received. Actual cash tax payable may differ as a result of the utilization of tax attributes available to OpenText. See footnote 3 (c).
