Page 17 of 24 Pages

This Amendment No. 6 (“Amendment No. 6”) amends the statement on Schedule 13D filed with the Securities and Exchange Commission (the “SEC”) on November 13, 2019 (the “Original Schedule 13D”), Amendment No. 1 filed with the SEC on January 30, 2020 (“Amendment No. 1”), Amendment No. 2 (“Amendment No. 2”) filed with the SEC on February 21, 2020, Amendment No. 3 filed with the SEC on April 1, 2020 (“Amendment No. 3”), Amendment No. 4 filed with the SEC on June 24, 2020 (“Amendment No. 4”) and Amendment No. 5 filed with the SEC on August 12, 2020 (“Amendment No. 5,” and together with the Original Schedule 13D, Amendment No. 1, Amendment No. 2, Amendment No. 3, Amendment No. 4 and Amendment No. 5, this “Schedule 13D”) with respect to the common stock, par value $0.001 per share (the “Common Stock”) of Cellular Biomedicine Group, Inc., a Delaware corporation (the “Issuer”).

Capitalized terms used herein and not otherwise defined in this Amendment No. 6 have the meanings set forth in the Original Schedule 13D, Amendment No. 1, Amendment No. 2, Amendment No. 3, Amendment No. 4 or Amendment No. 5. This Amendment No. 6 amends Items 4 and 5 as set forth below.

Item 4.

Purpose of Transaction

Item 4 of the Schedule 13D is hereby amended and supplemented by adding the following:

On February 8, 2021, a special meeting of stockholders of the Issuer was held. At the special meeting, the Issuer’s stockholders voted to approve the proposal to adopt the Merger Agreement by the affirmative vote of the holders of (a) at least a majority of all outstanding shares of Common Stock of the Issuer and (b) at least a majority of all outstanding shares of Common Stock of the Issuer owned by the Public Stockholders (as defined in the Merger Agreement).

Pursuant to the respective Support Agreements, the Rollover Shareholders have agreed, among other things, to (i) cancel the Rollover Shares for no cash consideration and (ii) subscribe for newly issued shares of Parent at or immediately prior to the Effective Time (as defined below), in each case, subject to the terms and conditions thereof. The information disclosed in this paragraph does not purport to be complete and is qualified in its entirety by reference to the Consortium Support Agreement, a copy of which is filed as Exhibit 18 to the Schedule 13D and is incorporated herein by reference in its entirety.

On February 19, 2021, the Issuer filed a Certificate of Merger with the Secretary of State of the State of Delaware, pursuant to which the Merger became effective. As of the effective time of the Merger (the “Effective Time”), each share of the Issuer’s Common Stock issued and outstanding prior to the effective time, other than the Excluded Shares (as defined in the Merger Agreement) that have been cancelled for no consideration, has been converted into the right to receive $19.75 per share in cash, without interest and net of any applicable withholding taxes. The Issuer ceased to be a publicly traded company and has become a wholly owned subsidiary of Parent.

As a result of the Merger, the Common Stock of the Issuer has ceased to trade on the NASDAQ prior to opening of trading on February 19, 2021 and became eligible for delisting from NASDAQ and termination of registration under the Act. The Issuer has requested that trading of its Common Stock on NASDAQ be suspended prior to opening of trading on February 19, 2021. The Issuer requested that NASDAQ file with the Commission a Form 25 relating to the delisting of the Issuer’s Common Stock from NASDAQ and the deregistration of the Issuer’s registered securities. The Issuer intends to file a Form 15 with the Commission under the Act, requesting the deregistration of the Issuer’s shares of Common Stock, under Section 12(g) of the Act and the suspension of the Issuer’s reporting obligations under Section 15(d) of the Act. The Issuer’s obligations to file with the Commission certain reports and forms, including Form 10-K, Form 10-Q and Form 8-K, will be suspended immediately as of the filing date of the Form 15 and will cease once the deregistration becomes effective.

The foregoing description of the Merger does not purport to be complete, and is qualified in its entirety by reference to the Merger Agreement, which is filed as Exhibit 13 to the Schedule 13D and is incorporated herein by reference in its entirety.

Item 5.	Interest in Securities of the Issuer

	Item 5 of the Schedule 13D is hereby amended and restated in its entirety to read as follows: The information contained on each of the cover pages of this Amendment No. 6 and the information set forth or incorporated in Items 2, 3, 4, and 6 are hereby incorporated herein by reference.

(a)-(b)	As a result of the Merger, the Reporting Persons do not beneficially own any shares of Common Stock or have any voting power or dispositive power over any shares of Common Stock.

(c)	The second paragraph in Item 4 of this Amendment No. 6 is incorporated herein by reference and is qualified in its entirety by reference to the Consortium Support Agreement. Except as set forth under Item 4 and this Item 5, the Reporting Persons have not effected any transactions in the class of securities reported herein in the last 60 days.
(d)	Not applicable.

(e)	As a result of the transactions described in Item 4, as of February 19, 2021, each of the Reporting Persons ceased to be the beneficial owner of more than 5% of the Issuer’s Common Stocks. Therefore, this Amendment No. 6 constitutes the final amendment to the original Schedule 13D or Schedule 13G.
