Item 8.01 Other Events

As previously announced by Open Text Corporation (OpenText or the Company) on September 12, 2016, and reported on OpenText’s Current Report on Form 8-K dated September 12, 2016, the Company entered into a Master Acquisition Agreement dated September 12, 2016 (the Master Acquisition Agreement), with EMC Corporation, a Massachusetts corporation, EMC International Company, a company organized under the laws of Ireland, and EMC (Benelux) B.V., a besloten vennootschap organized under the laws of Netherlands (collectively referred to as Dell-EMC), pursuant to which OpenText has agreed to acquire (the Anticipated Acquisition) certain assets and assume certain liabilities of the enterprise content division of Dell-EMC (the ECD Business). The Anticipated Acquisition is expected to close within 90 to 120 days of the date of the Master Acquisition Agreement and is subject to customary regulatory approvals and closing conditions.

Filed herewith under the exhibits are the following:

The Company is not yet required to file the historical financial statements of the ECD Business under Article 3-05 of Regulation S-X under the Securities Act of 1933, as amended (the “Securities Act”), or pro forma financial statements giving effect to the Anticipated Acquisition under Article 11 of Regulation S-X under the Securities Act on a Current Report on Form 8-K. However, the Company is filing the historical audited and unaudited financial statements of the ECD Business and the unaudited pro forma condensed consolidated financial statements with this Current Report on Form 8-K to aid investor understanding and to comply with the rules of the Canadian securities regulatory authorities in connection with a proposed offering of its common shares that is being made in each of the provinces of Canada in addition to the United States.

The Acquisition

On September 12, 2016, OpenText entered into the Master Acquisition Agreement to acquire the ECD Business. The purchase price for the Anticipated Acquisition, which is payable in cash, is approximately $1.62 billion.

OpenText expects the initial closing of the Anticipated Acquisition to take place within 90 to 120 days of the date of the Master Acquisition Agreement, except in certain jurisdictions where requirements of local law require the transfer of local assets and liabilities to be deferred to a later date. The consummation of the Anticipated Acquisition is subject to certain customary conditions. The consummation of the Anticipated Acquisition is not subject to any financing condition. Further information about the Anticipated Acquisition, including a copy of the Master Acquisition Agreement, is contained in OpenText’s Current Report on Form 8-K filed with the SEC and the applicable Canadian securities regulatory authorities on September 13, 2016 and September 12, 2016, respectively.

The ECD Business

The following information should be read in conjunction with the financial statements of the ECD Business as of and for the years ended December 31, 2015 and 2014, and as of September 30, 2016 and for the nine months ended September 30, 2016 and 2015, included in this Current Report on Form 8-K as Exhibit 99.1 and Exhibit 99.2.

The ECD Business provides enterprise software and cloud solutions that help organizations leverage their business content throughout its lifecycle to drive their digital agenda. The ECD Business’ offerings include enterprise content management solutions and archiving software. The ECD Business’ enterprise content management solutions enable the digitization and flow of content through organizations and include intelligent capture of information, enterprise content library services, customer communications,

information governance and compliance as well as purpose built industry solutions. The ECD Business’ archiving software helps customers take cost out of their current information technology (IT) environments by archiving inactive information to decommission legacy applications and make their current applications run better.

The ECD Business is headquartered in Pleasanton, California. The ECD Business employs approximately 2,000 individuals and has more than 5,600 customers worldwide across the Americas, the “EMEA” region, which primarily consists of countries in Europe, Africa, and the Middle East, and the “Asia Pacific” region, which primarily consists of Japan, Australia, China, Korea, Philippines, Singapore and New Zealand. Customers of the ECD Business operate in a wide range of industry verticals, including those in which OpenText has a strong presence as well as those that complement OpenText’s current industry focus. For the year ended December 31, 2015, the ECD Business had revenue of approximately $581 million and gross profit of $384 million, compared to $629 million and $404 million in 2014, respectively. From 2014 to 2015, the ECD Business’ gross margins increased from 64.2% to 66.1%.

The ECD Business offers a suite of leading Enterprise Content Management (ECM) solutions with deep industry focus, including the Documentum™, InfoArchive™ and LEAP™ product families, as well as a secondary portfolio of related products. The Anticipated Acquisition is expected to deepen OpenText’s existing Enterprise Information Management (EIM) offerings with a substantial portfolio focused on ECM and Information Life Cycle Management markets.

The ECD Business markets and sells its products through a direct sales force and indirect channels such as independent distributors and value-added resellers.

Strategic Rationale for the Anticipated Acquisition

We anticipate the Anticipated Acquisition will provide several significant strategic benefits to OpenText, including the following:

3

Preliminary Financial Impact of the Anticipated Acquisition

The Company believes that the Anticipated Acquisition will contribute strong recurring revenues, net income and operating cash flow to OpenText. We expect to be able to align the ECD Business with OpenText’s target adjusted operating margin profile within 12 months of the completion of the Anticipated Acquisition, driven in large part by anticipated cost savings realized from the following areas:

We expect to incur non-recurring, one-time transition costs of approximately $15 million related to anticipated IT integration, employee on-boarding and contract negotiation, in the first year post closing. In addition, OpenText may incur other non-recurring, one-time transaction charges related to severance expenses and restructuring associated with the Anticipated Acquisition. These charges are similarly expected to be realized in the first year after closing.

OpenText anticipates that the Anticipated Acquisition will be accretive to the Company’s earnings per share (EPS) and non-GAAP-based EPS, beginning in the quarter the Anticipated Acquisition closes.

We caution you that OpenText may not realize the anticipated benefits of the Anticipated Acquisition. Additionally, the ECD Business is subject to risks similar to those applicable to OpenText’s existing business, and OpenText will continue to be subject to those risks following the Anticipated Acquisition. Such risks may be exacerbated should the Anticipated Acquisition close and the ECD Business’ products are added to OpenText’s existing EIM portfolio. See “Risk Factors” in Item 1A of OpenText’s Annual Report on Form 10-K for the fiscal year ended June 30, 2016 and in Item 1A of OpenText’s Quarterly Report on Form 10-Q for the quarter ended September 30, 2016.

Forward-Looking Statements

This report contains forward-looking statements concerning the future performance of OpenText’s business, its operations and its financial results and condition, including with respect to the Anticipated Acquisition, the financing transactions related to the Anticipated Acquisition, the anticipated cost savings from the Anticipated Acquisition and accretion to EPS and non-GAAP-based EPS beginning in the quarter the Anticipated Acquisition closes, and the anticipated integration of the ECD Business. Forward-looking statements are identified by words or phrases such as “anticipates”, “expects”, “believes”, “estimates”, “intends”, “could”, “may”, “plans”, “predicts”, “projects”, “will”, “would”, “foresees” and other similar expressions or the negative of these terms. These statements reflect beliefs and assumptions which are based on OpenText’s perception of historical trends, current conditions and expected future developments, as well as other factors management believes are appropriate in the circumstances. OpenText’s beliefs and assumptions are inherently subject to significant business, economic, competitive and other uncertainties and contingencies regarding future events and, as such, are subject to change. OpenText’s beliefs and assumptions may prove to be inaccurate and consequently the Company’s actual results could differ materially from the expectations set out herein.

4

Actual results or events could differ materially from those contemplated in such forward-looking statements as a result of risks and uncertainties. Certain of these risks and uncertainties are described from time to time in OpenText’s filings with the SEC, including, but not limited to OpenText’s Annual Report on Form 10-K for the fiscal year ended June 30, 2016 and Quarterly Report on Form 10-Q for the quarter ended September 30, 2016, as well as documents filed with securities regulatory authorities in Canada. If any of these risks or uncertainties materialize or any of these assumptions prove incorrect, the actual results or performance of OpenText and its consolidated subsidiaries could differ materially from those expressed or implied by forward-looking statements. Any forward-looking statement the Company makes in this report speaks only as of the date on which it is made. New risks and uncertainties arise from time to time, and it is impossible for the Company to predict these events or how they may affect the Company. In any event, these and other important factors may cause actual results to differ materially from those indicated by the Company’s forward-looking statements. The Company has no duty, and does not intend, to update or revise the forward-looking statements made in this document, except as may be required by law. In light of these risks and uncertainties, future events or circumstances described in any forward-looking statement in this document might not occur.
