Explanatory Note


This Current Report on Form 8-K/A (Amendment No. 1) amends the Current Report on Form 8-K filed with the Securities and Exchange Commission (the “SEC”) by Xenetic Biosciences, Inc. (the “Company”) on March 4, 2019 (the “Original 8-K”) announcing, among other things, the signing of an agreement to acquire the novel CAR T (“Chimeric Antigen Receptor T Cell”) platform technology, called “XCART,” a proximity-based screening platform capable of identifying CAR constructs that can target patient-specific tumor neoantigens, with a demonstrated proof of mechanism in B-cell Non-Hodgkin lymphomas.


This Amendment No. 1 is being filed solely for the purpose of replacing Exhibit 2.1 and Exhibit 10.1 from the Original 8-K with a new Exhibit 2.1 and Exhibit 10.1 in connection with the SEC’s new rules and procedures for exhibits containing immaterial, competitively harmful information and the Company’s withdrawal of its confidential treatment request pertaining to the same exhibits.


Except as specifically provided otherwise herein, this Amendment No. 1 does not reflect events occurring after the date of the filing of the Company's Original 8-K, or modify or update those disclosures that may have been affected by subsequent events. Accordingly, this Amendment No. 1 should be read in conjunction with the Original 8-K.




In connection with the Transaction, the Company has filed with the Securities and Exchange Commission (the “SEC”), a registration statement on Form S-4 that includes a combined preliminary proxy statement/prospectus. This communication is not a substitute for any proxy statement, registration statement, proxy statement/prospectus or other documents the Company may file with the SEC in connection with the Transaction. INVESTORS AND SECURITY HOLDERS ARE URGED TO READ CAREFULLY AND IN THEIR ENTIRETY THESE DOCUMENTS, ANY AMENDMENTS OR SUPPLEMENTS TO THESE DOCUMENTS, AND OTHER DOCUMENTS FILED BY THE COMPANY WITH THE SEC IN CONNECTION WITH THE TRANSACTION, BECAUSE THESE DOCUMENTS CONTAIN IMPORTANT INFORMATION.

This communication is not a solicitation of a proxy from any investor or security holder. The Company, its respective directors, executive officers and other members of its management and employees may be deemed to be participants in the solicitation of proxies from shareholders of the Company in connection with the Transaction. Information regarding the persons who may, under the rules of the SEC, be deemed participants in the solicitation of proxies in connection with the Transaction, including a description of their direct or indirect interests, by security holdings or otherwise, will be set forth in the relevant materials when filed with the SEC.
