Exhibit (a)(5)(vii)

E-mail Communication to Employees of Actuate Corporation dated January 2, 2015

Actuate employees,

Below are some questions and answers regarding the pending OpenText tender offer:

1. What will happen to my stock options?

At the closing of the merger (which will occur as promptly as practicable after the consummation of the tender offer), all Actuate options, whether vested or unvested, will be cashed out at the spread between $6.60 and the strike price of the option, and you do not need to exercise such options in order to receive this payment (less any required tax withholding) for them. Options with a strike price equal to or higher than $6.60 will be cancelled.

2. What will happen to my RSUs?

At the closing of the merger, all Actuate RSUs will become converted into the right to receive $6.60 in cash per RSU. This cash will be paid out on the same vesting and settlement schedules as originally applied to your RSUs, except that on the one-year anniversary of the closing of the merger, all such cash payments will vest and you will receive $6.60 per converted RSU that would have still been unvested on the one-year anniversary, which will be paid pursuant to the original settlement schedule that applied to such converted RSU (less any required tax withholding). During this one year period, you will continue to have the “double trigger” acceleration protection that currently applies to your RSUs.

3. What will happen to the Actuate shares that I hold through the Actuate ESPP?

Actuate shares that you currently hold will be treated as described in Question #4 below, regardless of whether you acquired them through the Actuate ESPP or any other method.

Until the earlier of (1) the end of the current ESPP offering period (which expires on January 31, 2015) and (2) the closing of the merger, payroll deductions will be made in accordance with your elections as they were in effect on December 5, 2014 (and you may not change your payroll deductions from the rate in effect on December 5, 2014, other than to discontinue your participation in the ESPP in accordance with the terms of the ESPP).

If the tender offer is consummated, the current ESPP offering period will be terminated early (effective prior to the expiration time of the tender offer) and your accumulated contributions to date will be used to purchase Actuate shares. You do not have to take any action with respect to such shares; rather, they will be converted at the closing of the merger into the right to receive $6.60 per share, net to the seller in cash, without interest and less any required tax withholding. If there are any accumulated contributions that were not used to purchase Actuate shares, then they will be refunded to you as promptly as practicable following the closing of the merger.

4. Aside from my stock options, RSUs and shares that would be acquired at the end of the current ESPP offering period, what will happen to my Actuate shares?

The tender offer from OpenText (which is being made through its affiliate, Asteroid Acquisition Corporation) is for all Actuate shares for $6.60 per share, net to the seller in cash, without interest and less any required tax withholding. All stockholders who properly tender their shares into the tender offer before the expiration time (9:00 A.M., New York City time, on January 16, 2015, unless the tender offer is extended or earlier terminated) will receive payment for their shares as soon as practicable following consummation of the tender offer.

If you are a stockholder and hold your shares through a broker (such as E*Trade), you will receive information (including by e-mail) from your broker regarding how to tender your shares. Please follow the instructions from your broker, which may require logging into your brokerage account with a “control number” and giving an affirmative instruction to your broker to tender your shares into the tender offer. If you have questions, we would recommend contacting your broker first; however, if you do not know your broker’s number or they cannot answer your questions, you may also contact D.F. King & Co., Inc., the Information Agent for the tender offer, with any questions. They can be reached at (877) 864-5059 or actuate@dfking.com. With respect to Actuate shares that you hold in an E*Trade account, the same procedure applies whether the shares were acquired through the Actuate ESPP or through any other method.

If you are a stockholder and do not hold your shares through a broker, you will receive printed materials with instructions on how to tender your shares. If you have not yet received those materials or have any questions, please contact D.F. King & Co., Inc., the Information Agent for the tender offer. They can be reached at (877) 864-5059 or actuate@dfking.com.

If you do not tender your shares and thereafter the tender offer is consummated, all Actuate shares will be converted in the merger into the right to receive the same amount of cash per share as if you had tendered your shares ($6.60 in cash, without interest and less any required withholding taxes). However, to ensure that you receive your payment as soon as practicable, we would encourage you to follow the requisite instructions and tender your shares prior to January 16, 2015.
