On June 22, 2020, the Issuer, Vector Holdco, Vector Fund ESC, Vector Fund FD (Vector Holdco, Vector Fund ESC and Vector Fund FD, collectively the “Investors”) and Blackstone Tactical Opportunities Fund—FD (Cayman)—NQ L.P. (the “VCOC Investor”) entered into an Investment Agreement (the “Investment Agreement”), pursuant to which the Issuer issued and delivered to the Investors, and the Investors purchased an aggregate number of 150,000 Series A perpetual convertible preferred shares, par value US$0.00001 per share (the “Series A Preferred Shares”), for an aggregate purchase price of US$150 million. Such Series A Preferred Shares will be convertible, at any time on and after the original issuance date, at the option of holders, into Class A Ordinary Shares at a conversion price of US$2.8333 per Class A Ordinary Share, or into ADSs at a conversion price of US$17.00 per ADS (such Class A Ordinary Shares and ADSs, the “Conversion

Securities”). The conversion prices are subject to adjustment under the terms of the Certificate of Designation (the form of which is attached as Exhibit A to the Investment Agreement). The Issuer will have the right to effect a mandatory conversion at its election, if its ADSs achieve a price threshold of 200% of the conversion price for a specified period. Such Series A Preferred Shares will bear dividend at a rate of 4.5% per annum and rank senior to the Issuer’s ordinary shares in liquidation.

Except as otherwise permitted by the Investment Agreement, no Investors shall be permitted to (i) within the six months immediately following the original issuance date, transfer any Conversion Securities to any other person; or (ii) until the first anniversary of the original issuance date, transfer any Series A Preferred Shares to any other person, without the Issuer’s prior written consent. In addition, subject to certain exceptions, without the Issuer’s prior written consent, the Investors may not transfer Conversion Securities or Series A Preferred Shares representing more than 1% of the Issuer’s total outstanding shares on anas-converted basis to any restricted person as identified in the Investment Agreement.

In connection with the Investment Agreement, the Issuer and the Investors executed and delivered a registration rights agreement, on June 26, 2020 (the “Registration Rights Agreement”), pursuant to which the Investors are entitled to customary demand registration rights, piggyback registration rights and FormF-3 or FormS-3 registration rights with respect to the resale of Class A Ordinary Shares (including those represented by ADSs) owned by the Investors (including those issued or issuable upon conversion of the Series A Preferred Shares held by the Investors).

The transactions contemplated by the Investment Agreement (including the issuance of Series A Preferred Shares by the Issuer to the Investors) were consummated on June 26, 2020.

The funds required for the Investors to purchase the Series A Preferred Shares were obtained from capital contributions from partners of the Investors. No additional consideration was or will be paid by the Reporting Persons for the receipt of such Series A Preferred Shares.

The foregoing summary of the Investment Agreement and the Registration Rights Agreement is qualified in its entirety by the full text of the Investment Agreement and the Registration Rights Agreement, copies of which are filed as Exhibit 99.2 and Exhibit 99.4 to this Schedule 13D.

Item 4. Purpose of the Transaction.

The information set forth in Item 3 is incorporated by reference in its entirety into this Item 4.

The Reporting Persons acquired the securities reported herein for investment purposes, subject to the following:

Pursuant to the Investment Agreement, for so long as the Investors (together with their respective successors and permitted transferees) beneficially own at least 50% of the Series A Preferred Shares and/or the Conversion Securities that they collectively held at the closing of the Investment Agreement (in each case on an as converted basis) (the “Minimum Shareholding Requirement”), the Issuer shall (i) not incur, without prior written consent of the Investors, any financial indebtedness resulting in consolidated total borrowings immediately following such incurrence exceeding 6.5 times the adjusted EBITDA for the Issuer’s last fiscal year, (ii) not incur, without prior written consent of the Investors, any capital expenditures over US$100 million with respect to any single data center project or for any individual capital expenditure item, and (iii) consult with Investors in good faith before entering into any acquisition, disposal, sale, transfer, lease or any other material agreement involving an amount of US$100 million or more.
