This Amendment No. 14 to Schedule TO (together with any exhibits and annexes attached hereto, and as it may be amended or supplemented from time to time, this “Amendment”) is filed by (i) Fennec Acquisition Incorporated, a Delaware corporation (“Purchaser”) and a direct wholly-owned subsidiary of invoX Pharma Limited, a private limited company organized under the laws of England and Wales (“Parent”), which is a direct wholly-owned subsidiary of Sino Biopharmaceutical Limited, a company organized under the laws of the Cayman Islands (“SBP”), (ii) Parent and (iii) SBP, and amends and supplements the Tender Offer Statement on Schedule TO filed with the U.S. Securities and Exchange Commission (the “SEC”) on July 7, 2022 (together with any amendments and supplements thereto, the “Schedule TO”) by Purchaser, Parent, and SBP. The Schedule TO relates to the offer by Purchaser to purchase all of the issued and outstanding shares (each, a “Share” and collectively, the “Shares”) of common stock, par value $0.0001 per share, of F-star Therapeutics, Inc., a Delaware corporation (the “Company”), for $7.12 per Share, payable net to the holder in cash, without interest, subject to any withholding taxes required by applicable law, and on the terms and subject to the conditions set forth in the Offer to Purchase, dated July 7, 2022 (the “Offer to Purchase”), a copy of which is attached as Exhibit (a)(1)(a) to the Schedule TO, and in the accompanying letter of transmittal, a copy of which is attached as Exhibit (a)(1)(b) to the Schedule TO, and which, as each may be amended or supplemented from time to time, collectively constitute the “Offer.”

Except as otherwise set forth in this Amendment, the information set forth in the Schedule TO remains unchanged and is incorporated herein by reference to the extent relevant to the items in this Amendment. Capitalized terms used but not defined herein have the meanings ascribed to them in the Schedule TO.

Items 1 through 9; Item 11.

The Offer to Purchase and Items 1 through 9 and Item 11 of the Schedule TO, to the extent such Items 1 through 9 and Item 11 incorporate by reference the information contained in the Offer to Purchase, are hereby amended and supplemented by adding the following paragraph thereto:

“On February 1, 2023, Purchaser, Parent, and SBP extended the Offer to 5:00 p.m., Eastern Time, on February 8, 2023, unless further extended. The Offer was previously set to expire at 5:00 p.m., Eastern Time, on January 31, 2023. The Expiration Date is being extended in order to afford the Parties additional time to review, discuss and negotiate mitigation terms with CFIUS. The Depositary has advised Purchaser, Parent, and SBP that, as of 5:00 p.m., Eastern Time, on January 31, 2023, 15,305,013 Shares had been validly tendered into and not properly withdrawn from the Offer, representing approximately 69.57% of the outstanding Shares, and an additional approximately 1,735,138 Shares tendered pursuant to a notice of guaranteed delivery.

To afford the Parties additional time to negotiate the terms of a mitigation agreement and continue discussions with CFIUS, on January 30, 2023, the Parties voluntarily withdrew and immediately refiled the voluntary notice at the request of CFIUS. CFIUS’ acceptance of the refiled voluntary notice is effective as of January 31, 2023. Contemporaneously with the voluntary withdrawal and refiling, Purchaser, Parent, and the Company entered into Amendment No. 5 (“Amendment No. 5”) to the Merger Agreement on January 31, 2023. Amendment No. 5 extends the End Date of the Merger Agreement from “one (1) minute past 11:59 p.m., Eastern Time, on January 31, 2023” to “one (1) minute past 11:59 p.m., Eastern Time, on February 10, 2023.””

Amendment No. 5 extends the End Date of the Merger Agreement from “one (1) minute past 11:59 p.m., Eastern Time, on January 31, 2023” to “one (1) minute past 11:59 p.m., Eastern Time, on February 10, 2023.”

Other than as expressly modified pursuant to Amendments No. 1, 2, 3, 4 and 5, the Merger Agreement, which was previously filed as Exhibit 2.1 to the Company’s Current Report on Form 8-K filed with the Securities and Exchange Commission on June 23, 2022, remains in full force and effect as originally executed on June 22, 2022. The foregoing description of Amendment No. 5 does not purport to be complete and is subject to, and qualified in its entirety by, the full text of Amendment No. 5 attached as Exhibit (d)(13) hereto and incorporated herein by reference.”

Section 11 — “The Merger Agreement; Other Agreements” of the Offer to Purchase is hereby amended and supplemented by adding the following paragraphs at the end of the subsection titled “Termination”:

“As described above, the Merger Agreement may be terminated by either Parent or the Company, subject to certain exceptions, if the Offer Acceptance Time has not occurred on or prior to the End Date. On January 31, 2023, the Company, Purchaser, and Parent entered into Amendment No. 5 to extend the End Date from “one (1) minute past 11:59 p.m., Eastern Time, on January 31, 2023” to “one (1) minute past 11:59 p.m., Eastern Time, on February 10, 2023”. The Parties have extended the End Date to afford the Parties additional time to negotiate the terms of a mitigation agreement and continue discussions with CFIUS.”

CFIUS’ acceptance of the refiled voluntary notice is effective as of January 31, 2023. Contemporaneously with the voluntary withdrawal and refiling, Purchaser, Parent, and the Company entered into Amendment No. 5 (“Amendment No. 5”) to the Merger Agreement on January 31, 2023.
