EXPLANATORY NOTE

IN8bio, Inc. (the “Company”) is filing this Amendment No. 1 to its Annual Report on Form

10-K

(this “Amendment”), originally filed with the Securities and Exchange Commission (the “SEC”) on March 13, 2025 (the “Initial Filing”). This Amendment is being filed solely to correct the exhibit list contained in Item 15 of Part IV of the Initial Filing.

In connection with the filing of this Amendment, the Company is including new certifications of its principal executive officer and principal financial officer pursuant to Section 302 of the Sarbanes-Oxley Act of 2002. Accordingly, Item 15 of Part IV of the Initial Filing has also been amended to reflect the filing of the new certifications. Since no new financial statements have been included in this Amendment and this Amendment does not contain or amend any disclosure with respect to Items 307 and 308 of

Regulation S-K,

paragraphs 3, 4, and 5 of the certifications have been omitted. In addition, because no financial statements are contained within this Amendment, the Company is not including certifications pursuant to Section 906 of the Sarbanes-Oxley Act of 2002.

Except as contained herein, this Amendment does not modify or update disclosures contained in the Initial Filing. This Amendment should be read in conjunction with the Company’s other filings made with the SEC subsequent to the date of the Initial Filing.

In this Amendment, unless the context requires otherwise, all references to “we,” “our,” “us,” “IN8bio” and the “Company” refer to IN8bio, Inc.
