Introductory Note

This Amendment No. 5 to Schedule 13D (this “Amendment No. 5”) amends and supplements the Schedule 13D filed with the Securities and Exchange Commission on November 3, 2017, as amended by Amendment No. 1 filed on March 14, 2019, Amendment No. 2 filed on March 15, 2020, Amendment No. 3 filed on March 10, 2021, and Amendment No. 4 filed on January 3, 2022 (the “Original Schedule 13D” and, together with this Amendment No. 5, this “Schedule 13D”), and is being filed on behalf of Mr. Li and Blue Dolphins in respect of the Class A ordinary shares, par value US$0.0005 per share (the “Class A Ordinary Shares”), and Class B ordinary shares, par value US$0.0005 per share (the “Class B Ordinary Shares” and, together with the Class A Ordinary Shares, the “Shares”), of Sea Limited, an exempted company incorporated with limited liability under the laws of the Cayman Islands (the “Issuer”). 

Unless otherwise stated herein, the Original Schedule 13D remains in full force and effect. All capitalized terms used in this Amendment No. 5 but not defined herein shall have the meanings ascribed to them in the Original Schedule 13D.

Item 4. Purpose of Transaction.

Item 4 of the Schedule 13D is hereby deleted in its entirety and substituted with the following:

The information set forth or incorporated by reference in Items 3, 5 and 6 of this Schedule 13D is hereby incorporated by reference in this Item 4.

The Reporting Persons acquired the Class B Ordinary Shares over which they have sole dispositive power prior to the Issuer’s initial public offering, which acquisition was financed by the personal funds of Mr. Li. These shares were acquired for investment purposes.

Mr. Li acquired the Class A Ordinary Shares over which he has sole dispositive power through the exercise of options or vesting of restricted share units granted under the 2009 share incentive plan of the Issuer. The option exercise price was financed by the personal funds of Mr. Li. The other Shares covered by this Schedule 13D are deemed beneficially owned by Mr. Li due to irrevocable voting proxies granted by various shareholders to Mr. Li.

At the annual general meeting of shareholders of the Company held on February 14, 2022 in Singapore (the “AGM”), the Company’s shareholders approved as a special resolution that the Company’s Eighth Amended and Restated Memorandum and Articles of Association be amended and restated by their deletion in their entirety and by the substitution in their place of the Company’s Ninth Amended and Restated Memorandum and Articles of Association to increase the voting power of each Class B Ordinary Share from three (3) votes to fifteen (15) votes on all matters subject to vote at general meetings of the Company and to reflect other relevant changes (the “Special Resolution”).

Immediately upon the Special Resolution being approved by the shareholders at the AGM, each of Tencent Holdings Ltd. and its affiliates (“Tencent”) converted all the Class B Ordinary Shares held or beneficially owned by it to Class A Ordinary Shares. Upon effectiveness of such conversion by Tencent, all outstanding Class B Ordinary Shares are currently beneficially owned by Mr. Li, the Issuer’s founder, Chairman and CEO. At the same time, the Irrevocable Proxy between Tencent and Mr. Li dated September 1, 2017 was also terminated.

Other than as set forth in this Schedule 13D, the Reporting Persons have no present plans or proposals which relate to or would result in any of the matters set forth in clauses (a) through (j) of Item 4 of Schedule 13D; provided that the Reporting Persons may, at any time, review or reconsider their position with respect to the Issuer and reserve the right to develop such plans or proposals.
