Introductory Note

On May 19, 2022, Magnesium Bidco Limited, a private limited company incorporated in England & Wales (“Buyer”), completed the previously announced acquisition of Mimecast Limited, a public limited company incorporated under the laws of the Bailiwick of Jersey (“Mimecast” or the “Company”), by means of a court-sanctioned scheme of arrangement (the “Scheme of Arrangement”) under Part 18A of the Companies (Jersey) Law 1991 (the “Transaction”) pursuant to the previously announced transaction agreement, dated as of December 7, 2021 (the “Transaction Agreement”), by and between Mimecast and Buyer. Upon the consummation of the Transaction, Mimecast became a wholly-owned subsidiary of Buyer. Buyer is an affiliate of Permira Advisers LLC (“Permira”).

Item 1.01.

Entry into a Material Definitive Agreement.

In connection with the transactions contemplated by the Transaction Agreement and in order to pay for a portion of the Consideration, Mimecast BorrowerCo, Inc. (a Delaware corporation owned and sponsored by certain Permira funds), as borrower, and other guarantors party thereto, including the Company, entered into a Credit Agreement dated as of May 19, 2022, with Ares Capital Corporation, as Administrative and Collateral Agent, and PNC Bank, National Association, as Revolving Administrative Agent.

Item 1.02.

Termination of a Material Definitive Agreement.

At the effective time of the Scheme of Arrangement (the “Effective Time”), the credit agreement, dated as of July 23, 2018, as amended, by and among Mimecast, certain of the Company’s subsidiaries party thereto, as guarantors, certain financial institutions party thereto from time to time, as lenders, and JPMorgan Chase Bank, N.A., as administrative agent, was terminated, all obligations and guarantees thereunder were repaid and discharged (other than contingent obligations for which no claim has been made) and all liens granted in connection therewith were released.

The information contained in the Introductory Note of this Current Report on Form 8-K is incorporated by reference into this Item 1.02.

Item 2.01.

Completion of Acquisition or Disposition of Assets.

At the Effective Time, all Company ordinary shares (other than the Rollover Company Shares as described below) then outstanding were transferred from the Company shareholders to Buyer in accordance with the terms of the Scheme of Arrangement and the Transaction Agreement, and the Company shareholders became entitled to receive, in exchange for each ordinary share of the Company, $80.00 in cash, without interest, (the “Per Share Consideration”), subject to required withholding taxes.

At the Effective Time, or promptly thereafter on the day of the occurrence of the Effective Time, the Company’s Register of Members was updated in accordance with the terms of the Scheme of Arrangement to reflect the transfer of the Company ordinary shares under the Scheme of Arrangement to Buyer.

Pursuant to the Transaction Agreement, immediately prior to the Effective Time, by virtue of the Transaction and without any action on the part of the holders thereof, each vested Company share option was canceled and extinguished and automatically converted into the right to receive from Buyer an amount in cash equal to the product obtained by multiplying (i) the excess, if any, of the Per Share Consideration over the per share exercise price of such vested company share option, by (ii) the aggregate number of Company ordinary shares that were issuable upon exercise of such vested Company share option immediately prior to the Effective Time. Each vested Company share option that was outstanding immediately prior to the Effective Time that had a per-share exercise price that was equal to or greater than the Per Share Consideration was automatically canceled as of the Effective Time for no consideration.

Additionally, pursuant to the Transaction Agreement, immediately prior to the Effective Time, by virtue of the Transaction and without any action on the part of the holders thereof, each outstanding vested Company RSU award was canceled and automatically converted into the right to receive from Buyer an amount in cash equal to the product obtained by multiplying (i) the aggregate number of Company ordinary shares subject to such vested Company RSU award by (ii) the Per Share Consideration.

In addition, pursuant to the Transaction Agreement, immediately prior to the Effective Time, each Company share option and each Company RSU award (or portion thereof) that was outstanding as of immediately prior to the Effective Time and was not vested was, as of the closing, converted into and substituted with a cash award pursuant to the terms of the applicable Company share plan. Such cash award will remain subject to the same time-vesting terms and conditions that applied to the substituted Company share option or Company RSU award, as applicable, as in effect immediately prior to the Effective Time, including the requirement of continued service with Buyer or its affiliates through the applicable vesting date, and the applicable cash amounts shall be paid out, without interest and

less any applicable tax withholdings, on the next payroll date following the applicable vesting dates, as long as the applicable portion of the cash award became or becomes vested prior to the applicable holder’s termination of service with Buyer and its affiliates.

Pursuant to the Transaction Agreement, each of the following Company share options and Company RSU awards were deemed vested: (i) the portion of each Company share option or Company RSU award that was outstanding and vested as of immediately prior to the Effective Time or that became vested by its terms and without further action by the Company as a result of the Transaction, (ii) one hundred percent (100%) of each Company share option and Company RSU award (whether vested or unvested) that was outstanding and held by a non-employee member of the Board of Directors of the Company immediately prior to the Effective Time (the “Board Equity Awards”) and (iii) with respect to each Company share option and Company RSU award that was outstanding as of the date of the Transaction Agreement, twenty-five percent (25%) of the portion of such award that was unvested as of immediately prior to the Effective Time (other than any Board Equity Award and certain other equity awards specified in the Agreement), with such twenty-five (25%) to be applied pro rata across each of such holder’s unvested and outstanding Company equity awards, by grant date, award type, and vesting date.

The foregoing summaries of the Transaction and the Transaction Agreement do not purport to be complete and are subject to, and qualified in their entirety by reference to, the full text of the Transaction Agreement, which was previously attached as Exhibit 2.1 to the Current Report on Form 8-K filed by Mimecast on December 7, 2021. The Transaction Agreement is incorporated herein by reference.

On May 18, 2022, Magnesium Topco Limited (“Topco”), an affiliate of Permira, entered into certain contribution and exchange agreements and a shareholders agreement with certain members of the management or board of directors of Mimecast (the “Rollover Parties”), whereby, following the granting of the order by the Royal Court of Jersey sanctioning the Scheme of Arrangement but prior to the Scheme Record Time (as defined in the Scheme of Arrangement), the Rollover Parties contributed certain of their Company ordinary shares (the “Rollover Company Shares”) to Topco in exchange for equity interests in Topco.

Item 3.01.

Notice of Delisting or Failure to Satisfy a Continued Listing Rule or Standard; Transfer of Listing.

Prior to the Effective Time, the Company ordinary shares were listed and traded on the Nasdaq Global Select Market (“NASDAQ”) under the trading symbol “MIME.” On May 19, 2022, Mimecast notified NASDAQ that the Transaction had become effective and requested that trading of the Company ordinary shares on NASDAQ be suspended prior to the opening of trading on May 19, 2022. In addition, Mimecast requested that NASDAQ promptly file with the Securities and Exchange Commission (the “SEC”) a Notification of Removal from Listing and/or Registration under Section 12(b) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), on Form 25 to delist the Company ordinary shares from NASDAQ. As a result, the Company ordinary shares will no longer be listed on NASDAQ. Upon effectiveness of such Form 25, Mimecast intends to file with the SEC a certification on Form 15 under the Exchange Act, requesting the deregistration of all of Mimecast’s securities registered under Section 12(g) of the Exchange Act and the suspension of Mimecast’s reporting obligations under Sections 13 and 15(d) of the Exchange Act.
