(c) The Company has prepared and filed the Registration Statement in conformity with the requirements of the Securities Act, which became automatically effective on February 11, 2025 (the “Effective Date”), including the Prospectus, and such amendments and supplements thereto as may have been required to the date of this Agreement. The Company and the transactions contemplated by this Agreement meet the requirements for use of Form S-3 under the Securities Act.

The Company agrees to pay the fees required by the SEC relating to the Shares within the time required by Rule 456(b)(1) of the Securities Act without regard to the proviso therein and otherwise in accordance with Rule 456(b) of the Securities Act and Rule 457(r) of the Securities Act. The Company has not received from the SEC any notice pursuant to Rule 401(g)(2) objecting to the use of the automatic shelf registration statement form. (d) The Common Stock is registered pursuant to Section 12(b) of the Exchange Act and is currently listed on the NYSE under the trading symbol “ACHR.” The Company has taken no action designed to terminate the registration of the Common Stock under the Exchange Act or delist the Common Stock from the NYSE. The Company (i) has not received any notification that the NYSE is contemplating a delisting of the Common Stock from the NYSE and

7 (ii) is in material compliance with all applicable listing requirements of the NYSE. The Common Stock is currently eligible for electronic transfer through the Depository Trust Company. (e) At the time of the filing of the Registration Statement and the Prospectus, at the earliest time thereafter that the Company or another offering participant made a bona fide offer (within the meaning of Rule 164(h)(2)) of the Shares, the Company was not and is not an “ineligible issuer” (as defined in Rule 405 of the Securities Act), including (i) the Company or any of its subsidiaries in the preceding three years not having been convicted of a felony or misdemeanor or having been made the subject of a judicial or administrative decree or order as described in Rule 405 and (ii) the Company in the preceding three years not having been the subject of a bankruptcy petition or insolvency or similar proceeding, not having had a registration statement be the subject of a proceeding under Section 8 of the Securities Act and not being the subject of a proceeding under Section 8A of the Securities Act in connection with the offering of Shares hereby, all as described in Rule 405 of the Securities Act, without taking account of any determination by the SEC pursuant to Rule 405 of the Securities Act that is it not necessary that the Company be considered an “ineligible issuer.” (f) The Transaction Documents have been duly authorized, validly executed and delivered by a duly authorized representative of the Company. The signature of the Company on each of the Transaction Documents is genuine, and such signatory has been duly authorized to execute each of the Transaction Documents. Assuming that each applicable Transaction Document is validly executed and delivered by a duly authorized representative of each Investor, such Transaction Document constitutes a legal, valid and binding obligation of the Company, enforceable against the Company in accordance with its terms, except as may be limited or otherwise affected by bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium or other laws relating to or affecting the rights of creditors generally.
