Amendment Description	Astrea Acquisition Corp. II (the “Company,” “we”, “our” or “us”) is filing this Amendment No. 1 to the Current Report on Form 10-Q/A (the “Amendment”) to amend its Quarterly Report on Form 10-Q for the quarter ended June 30, 2021, as originally filed with the U.S. Securities and Exchange Commission (the “SEC”) on August 23, 2021 (the “Original Filing”), to reflect changes to Note 2, Revision of Previously Issued Financial Statements. In the Company’s previously issued financial statement filed with the SEC on August 23, 2021, a portion of the public shares were classified as permanent equity to maintain stockholders’ equity greater than $5,000,000 on the basis that the Company could consummate its initial business combination only if the Company has net tangible assets of at least $5,000,001 under the Company’s charter. Thus, the Company can only complete a merger and continue to exist as a public company if there are sufficient public shares that do not redeem at the merger and so it was deemed appropriate to classify the portion of its public shares required to keep its stockholders’ equity above the $5,000,000 threshold as “shares not subject to redemption.” However, in light of recent comment letters issued by the Securities & Exchange Commission (“SEC”) to several special purpose acquisition companies, management re-evaluated the Company’s application of ASC 480-10-99 to its accounting classification of public shares. Upon re-evaluation, management determined that the public shares include certain provisions that require classification of the public shares as temporary equity regardless of the minimum net tangible asset required by the Company to complete its initial business combination. In addition, management determined that the over-allotment option granted to the underwriters is considered to be a freestanding financial instrument and meets the definition of a liability under ASC 480, “Distinguishing Liabilities from Equity” (ASC 480). The determination was based on the understanding that the over-allotment option may be exercised subsequent to the transfer of the securities from the underwriters to the investors and that the option should be detached from the initial securities before it is exercised. The over-allotment option liability is measured at fair value at inception and subsequently until it is exercised or expires, with changes in fair value presented in the statement of operations. On February 18, 2021, the underwriters fully exercised the option to purchase up to an additional 2,250,000 units. The over-allotment liability was eliminated upon the forfeiture of the unexercised option. As a result, the Company’s management, together with the audit committee of the Company’s board of directors (“Audit Committee”), determined that the Original Financial Statement should be restated in this Amendment No. 1. This Quarterly Report is also being filed to amend Part I, Item 4 “Controls and Procedures” of the Original Quarterly Report to include a revised conclusion that the disclosure controls and procedures were not effective due to the material weakness in the internal control over financial reporting related to the Company’s accounting for complex financial instruments, and Part II, Item 1A “Risk Factors” of the Original Quarterly Report in order to include a statement that the Company identified a material weakness in the internal control over financial reporting related to the Company’s accounting and reporting of complex financial instruments Except as described above, this Amendment does not amend, update, or change any other items or disclosures in the Original Filing and does not purport to reflect any information or events subsequent to the filing thereof. As such, this Amendment speaks only as of the date the Original Filing was filed, and we have not undertaken herein to amend, supplement or update any information contained in the Original Filing to give effect to any subsequent events. Accordingly, this Amendment should be read in conjunction with the Original Filing and our filings made with the SEC subsequent to the filing of the Original Filing, including any amendment to those filings.
