Item 6 Contracts, Arrangements, Understandings or Relationships With Respect to Securities of the Issuer

To provide financing for the acquisition by the Issuer of Interoute Communications Holdings S.A., a Luxembourg public limited liability company, the Issuer and the Fund entered into an Amended and Restated Securities Purchase Agreement, dated as of February 23, 2018, pursuant to which the Issuer agreed to sell to the Fund 170 shares of a newly created class of preferred stock of the Issuer, to be designated as the Series A Convertible Preferred Stock (the “Series A Preferred Stock”) for a total purchase price of $170 million. The 170 shares of Series A Preferred Stock issuable to the Fund would be convertible into 3,835,637 Shares (assuming there were no adjustments to the conversion price), reflecting a conversion price of $44.3212 per share. In order to simplify the issuance of the Shares, the Fund entered into the Purchase Agreement with the Issuer on May 30, 2018, providing for payment of the same aggregate purchase price contemplated by their purchase agreement dated as of February 23, 2018 but, instead of the Series A Preferred Stock, providing for the sale to them of that number of Shares into which their respective Series A Preferred Stock would have been converted upon issuance, such that the sale price per share would be the same as the conversion price of $44.3212 per share. This description of the Purchase Agreement is qualified in its entirety by reference to the full text of the Purchase Agreement, which is attached hereto at Exhibit 99.1 and incorporated by reference herein.

On May 31, 2018, the Fund and the Persons listed on Schedule 1 thereto entered into an Investor Rights Agreement (the “Investor Rights Agreement”). Pursuant to the Investor Rights Agreement, the Fund will be entitled to certain registration rights with respect to the Shares that it holds. In addition, the Fund is subject to a standstill provision during the period commencing on May 31, 2018 and ending on the earliest of (a) the date on which the beneficial ownership of the Fund and its affiliates collectively no longer represents at least five percent (5%) of the Shares of then outstanding Common Stock, (b) the three (3) year anniversary of May 31, 2018 and (c) the date of the consummation of a change of control (the “Standstill Period”). During the Standstill Period, the Fund agreed not to acquire beneficial ownership of any securities of the Issuer without the prior consent of the Issuer (which consent shall be deemed to have been granted if the Issuer does not affirmatively advise the Fund that the Issuer withholds such consent within one trading day after receiving such request for consent) so long as the total beneficial ownership of the Fund and its controlled affiliates in the Shares, after giving effect to such acquisitions, would not exceed 25% of the Issuer’s Total Voting Power at such time or take certain specified control actions toward the Issuer without the prior written approval of the Issuer or the Issuer’s board of directors. This description of the Investor Rights Agreement is qualified in its entirety by reference to the full text of the Investor Rights Agreement, which is attached hereto as Exhibit 99.2 and incorporated by reference herein.

On December 21, 2018, the Issuer granted consent (the “Consent Letter”) to the acquisition by the Fund and its controlled affiliates of Shares, at any time and from time to time, so long as the total beneficial ownership of the Fund and its controlled affiliates in the Shares, after giving effect to such acquisitions, would not exceed 25% of the Issuer’s Total Voting Power at such time. In addition, the Consent Letter provides that from the date of the letter and continuing until the later of (i) one year from the date of the letter and (ii) receipt of the approvals from the state public utility commissions for the State of Ohio and the State of Pennsylvania required in order for the Fund to acquire common stock representing 20% or more of the Issuer’s Total Voting Power, in any vote or action by written consent of the stockholders of the Issuer (including, without limitation, with respect to the election of directors), the Fund shall, and shall cause its controlled affiliates to, vote or execute a written consent with respect to the Voting-Restricted Shares held by the Fund and its controlled affiliates in accordance with the recommendation of the Issuer’s board or, if the Issuer’s board does not make a recommendation with respect to a particular matter, in proportion to the votes cast by the holders of the Issuer’s common stock other than the Fund and its controlled affiliates. The Fund also granted a related proxy to the Issuer. For purposes of this Consent Letter, (i) “Total Voting Power” means the aggregate number of votes which may be cast by all holders of outstanding common stock and all other securities of the Issuer entitled to vote in the election of directors and (ii) “Voting-Restricted Shares” means all shares of the Issuer’s common stock beneficially owned by the Fund and its controlled affiliates (and with respect to which such entities have voting rights) in excess of 19.9% of the Issuer’s Total Voting Power. This description of the Consent Letter is qualified in its entirety by reference to the full text of the Consent Letter, which is attached hereto as Exhibit 99.3 and incorporated by reference herein.

The Investment Manager is an investment adviser to its client, the Fund, which has the right to receive or the power to direct the receipt of dividends from, or the proceeds from the sale of, the Shares. The General Partner is the general partner of the Fund. Messrs. Sternberg and Stein are the managers of each of the Investment Manager and the General Partner.

The Reporting Persons are parties to an agreement with respect to the joint filing of this Schedule 13D and any amendments thereto. A copy of such agreement is attached as Exhibit 99.4 to this Schedule 13D and is incorporated by reference herein.

The Spruce House Partnership LP

c/o The Spruce House Partnership

435 Hudson Street — Suite 804

New York, NY 10014

Attention: Ben Stein and Zach Sternberg

Acquisition of GTT Communications, Inc. Securities

Messrs. Stein and Sternberg:

We refer to the Investor Rights Agreement, dated as of May 31, 2018, by and among GTT Communications, Inc., a Delaware corporation (the “Company”), and the Persons listed on Schedule I thereto, including The Spruce House Partnership LP (“Spruce House”). Each capitalized term used and not defined herein shall have the meaning assigned to such term in the Investor Rights Agreement.

Pursuant to Section 3.1.1(b) of the Investor Rights Agreement, the Company hereby consents to the acquisition by Spruce House and its controlled Affiliates of common stock of the Company, at any time and from time to time, so long as the total beneficial ownership of Spruce House and its controlled Affiliates in the Company’s common stock, after giving effect to such acquisitions, would not exceed 25% of the Company’s Total Voting Power at such time; provided that, if at any time the Company reasonably believes an acquisition by Spruce House or its controlled Affiliates of additional shares of the Company’s common stock will be treated as an “ownership change” as defined in Section 382 of the Code, the Company may notify Spruce House of such belief, and Spruce House shall not acquire any additional shares of the Company’s common stock until such time that Spruce House is advised by the Chief Financial Officer of the Company that the facts and circumstances giving rise to the Company’s reasonable belief that such acquisition would be treated as an “ownership change” as defined in Section 382 of the Code no longer apply. Upon Spruce House’s request from time to time, the Chief Financial Officer of the Company shall confirm whether the Company continues to reasonably believe that an acquisition by Spruce House or its controlled Affiliates of additional shares of the Company’s common stock would be treated as an “ownership change” as defined in Section 382 of the Code.

From the date of this letter and continuing until the later of (i) one year from the date of this letter and (ii) receipt of the approvals from the state public utility commissions for the State of Ohio and the State of Pennsylvania (the “PUC Approvals”) required in order for Spruce House to acquire common stock representing 20% or more of the Company’s Total Voting Power (the “End Date”), in any vote or action by written consent of the stockholders of the Company (including, without limitation, with respect to the election of directors), Spruce House shall, and shall cause its controlled Affiliates to, vote or execute a written consent with respect to the Voting-Restricted Shares held by Spruce House and its controlled Affiliates in accordance with the recommendation of the Company Board or, if the Company Board does not make a recommendation with respect to a particular matter, in proportion to the votes cast by the holders of the Company’s common stock other than Spruce House and its controlled Affiliates. For purposes of this agreement, (i) “Total Voting Power” shall mean the aggregate number of votes which may be cast by all holders of outstanding common stock and all other securities of the Company entitled to vote in the election of directors and (ii) “Voting-Restricted Shares” shall mean all shares of the Company’s common stock beneficially owned by

Spruce House and its controlled Affiliates (and with respect to which such entities have voting rights) in excess of 19.9% of the Company’s Total Voting Power. In furtherance of this paragraph, Spruce House and its controlled Affiliates hereby irrevocably appoint the Company and any individuals designated by the Company, and each of them individually, as the attorneys, agents and proxies, with full power of substitution and re-substitution in each of them, for Spruce House and its controlled Affiliates, and in the name, place and stead of Spruce House and its controlled Affiliates, to vote (or cause to be voted) in such manner as set forth in this paragraph the Voting-Restricted Shares that Spruce House and its controlled Affiliates are or may be entitled to vote at any meeting of the Company held after the date hereof (but prior to the End Date), whether annual or special and whether or not an adjourned meeting, and to act by written consent in lieu of a meeting to the extent permissible with respect to the Voting-Restricted Securities (the “Irrevocable Proxy”). The Irrevocable Proxy is coupled with an interest, shall be irrevocable and binding on any successor in interest of Spruce House and/or its controlled Affiliates and shall not be terminated by operation of law upon the occurrence of any event; provided, however, that notwithstanding any other provision hereof (i) the Irrevocable Proxy shall cease to apply to any shares upon the sale or transfer thereof by Spruce House or its controlled Affiliates to anyone other than Spruce House or its controlled Affiliates or any “group” (within the meaning of Section 13(d)(3) of the Securities Exchange Act of 1934) of which Spruce House or its controlled affiliates is a member and (ii) the Irrevocable Proxy shall terminate upon the earlier of the End Date or mutual agreement of the Company and Spruce House. The Irrevocable Proxy shall operate to revoke and render void any prior proxy as to any securities of the Company heretofore granted by Spruce House and its controlled Affiliates which is inconsistent herewith. Spruce House shall cause any of its controlled Affiliates that may from time to time beneficially own Voting-Restricted Shares, if and when requested by the Company from time to time, to promptly execute and deliver to the Company an irrevocable proxy, substantially in the form of the Irrevocable Proxy. This paragraph shall be effective only as to any shares of the Company’s common stock held by Spruce House and/or its controlled Affiliates that are, once purchased, Voting-Restricted Shares, and shall automatically cease to be effective and shall terminate upon any sale or transfer if, as result of such sale or transfer, Spruce House and its controlled Affiliates no longer hold any Voting-Restricted Shares (it being acknowledged that if Spruce House and its controlled Affiliates at any time cease to hold Voting-Restricted Shares but subsequently and prior to the End Date acquire shares of the Company that are Voting-Restricted Shares, this paragraph shall be effective as to such subsequently acquired shares). Nothing herein shall be construed to create any limitation on the sale, transfer or pledge of any shares of the Company’s common stock by Spruce House.
