SUPPLEMENT NO. 1, DATED JANUARY 21, 2026

(TO THE DEFINITIVE PROXY STATEMENT OF AA MISSION ACQUISITION CORP. DATED JANUARY 12, 2026)

SUPPLEMENT TO THE PROXY STATEMENT

This supplement to the Definitive Proxy Statement (the “Supplement”), supplements, updates and amends the Definitive Proxy Statement of the Company filed with the SEC on January 12, 2026. The following supplemental information should be read in conjunction with the Definitive Proxy Statement, which should be read in its entirety.

The Proposal No. 2 description on the cover page of the Letter to Shareholders of AA Mission Acquisition Corp. is hereby amended and restated as follows:

“A proposal, by at least two-thirds (2/3) of the then outstanding ordinary shares which are represented in person or by proxy and are voted at a general meeting of the Company, voting together as a single class, to further amend AAM’s investment management trust agreement, dated as of July 31, 2024, (the “Trust Agreement”), by and between the Company and Continental Stock Transfer & Trust Company (the “Trustee”), to allow the Company to extend the Termination Date up to twelve (12) times for an additional one (1) month each time from the Termination Date or Extended Date, as applicable, to February 2, 2027 (the “Trust Agreement Amendment”) by providing five days’ advance notice to the Trustee prior to the applicable Termination Date or Extended Date and depositing into the trust account (the “Trust Account”) $173,000, per one-month extension two (2) days prior to such Extension (the “Extension Payment”) until February 2, 2027 (assuming a Business Combination has not occurred) in exchange for a non-interest bearing, unsecured promissory note payable upon the consummation of a Business Combination (the “Trust Agreement Amendment Proposal”).”

The Twelfth paragraph on the cover page of the Letter to Shareholders of AA Mission Acquisition Corp. is hereby amended and restated as follows:

“Approval of the Trust Agreement Amendment Proposal requires the affirmative vote of at least two-thirds (2/3) of the then outstanding Ordinary Shares which are represented in person or by proxy and are voted at a general meeting of the Company, voting together as a single class pursuant to the Trust Agreement. If all outstanding Ordinary Shares are present at the Extraordinary General Meeting, then in addition to the Founder Shares, the Company will need 19,842,001 Public Shares, or 57.51% of the Public Shares, to vote in favor of the Trust Agreement Amendment Proposal to approve such proposal.”

The paragraph under the board order on the cover page of the Letter to Shareholders of AA Mission Acquisition Corp. is hereby amended and restated as follows:

“Your vote is very important. Whether or not you plan to attend the Extraordinary General Meeting, virtually or in person, please vote as soon as possible by following the instructions in the accompanying Proxy Statement to make sure that your shares are represented at the Extraordinary General Meeting. If you hold your shares in “street name” through a bank, broker or other nominee, you will need to follow the instructions provided to you by your bank, broker or other nominee to ensure that your shares are represented and voted at the Extraordinary General Meeting. The approval of the Extension Amendment Proposal requires a special resolution under Cayman Islands law, being the affirmative vote of the holders of at least two-thirds (2/3) of issued and outstanding Ordinary Shares entitled to vote and who, being present in person or represented by proxy at the Extraordinary General Meeting, or any adjournment thereof, vote on such matter. Approval of the Trust Agreement Amendment Proposal requires the affirmative vote of at least two-thirds (2/3) of the then outstanding Ordinary Shares which are represented in person or by proxy and are voted at a general meeting of the Company, voting together as a single class pursuant to the Trust Agreement. Approval of the Adjournment Proposal requires an ordinary resolution under Cayman Islands law, being the affirmative vote of the holders of at least a simple majority of the issued and outstanding Ordinary Shares entitled to vote and who, being present in person or represented by proxy at the Extraordinary General Meeting, or any adjournment thereof, vote on such matter. The presence, in person (including virtually) or by proxy, at the Extraordinary General Meeting of the holders of a majority of the Ordinary Shares entitled to vote as of the Record Date at the Extraordinary General Meeting shall constitute a quorum for the conduct of business at the Extraordinary General Meeting. Accordingly, if you fail to vote in person or by proxy at the Extraordinary General Meeting, your shares will not be counted for the purposes of determining whether the Extension Amendment Proposal, the Trust Agreement Amendment Proposal and the Adjournment Proposal are approved by the requisite majorities. If you fail to return your proxy card or fail to instruct your bank, broker or other nominee how to vote, and do not attend the Extraordinary General Meeting in person, the effect will be that your shares will not be counted for purposes of determining whether a quorum is present at the Extraordinary General Meeting and will not have any effect on whether the proposals are approved. If you are a shareholder of record and you attend the Extraordinary General Meeting and wish to vote in person, you may withdraw your proxy and vote in person.”

The fifth paragraph from the last on the cover page of the Notice of Extraordinary General meeting of AA Mission Acquisition Corp.

Approval of the Trust Agreement Amendment Proposal requires the affirmative vote of at least two-thirds (2/3) of the then outstanding Ordinary Shares and Ordinary Shares which are represented in person or by proxy and are voted at a general meeting of the Company, voting together as a single class pursuant to the Trust Agreement. If all outstanding Ordinary Shares are present at the Extraordinary General Meeting, then in addition to the Founder Shares, the Company will need 19,842,001 Public Shares, or 57.51% of the Public Shares to vote in favor of the Trust Agreement Amendment Proposal to approve such proposal.

The paragraph under “Questions and Answers About the Extraordinary General Meeting — What vote is required to approve the proposals presented at the Extraordinary General Meeting?” is hereby amended and restated as follows:

“The approval of the Extension Amendment Proposal requires a special resolution under Cayman Islands law, being the affirmative vote of holders of at least two-thirds (2/3) of the issued and outstanding Ordinary Shares entitled to vote and who, being present in person or represented by proxy at the Extraordinary General Meeting or any adjournment thereof, vote on such matter. Approval of the Trust Agreement Amendment Proposal requires the affirmative vote of at least two-thirds (2/3) of the Ordinary Shares which are represented in person or by proxy and are voted at the Extraordinary General Meeting, voting together as a single class. Approval of the Adjournment Proposal requires an ordinary resolution under Cayman Islands law, being the affirmative vote of the holders of at least a simple majority of the issued and outstanding Ordinary Shares entitled to vote and who, being present in person or represented by proxy at the Extraordinary General Meeting or any adjournment thereof, vote on such matter.”

The paragraph under “Questions and Answers About the Extraordinary General Meeting — How will the initial shareholders vote?” is hereby amended and restated as follows:

“The initial shareholders have advised AAM that they intend to vote any Ordinary Shares over which they have voting control, in favor of the Extension Amendment Proposal, the Trust Agreement Amendment Proposal, and, if necessary, the Adjournment Proposal. The initial shareholders and their respective affiliates are not entitled to redeem any Founder Shares in connection with the Extension Amendment Proposal. On the Record Date, the Sponsor, AAM’s directors, officers and its initial shareholders and their respective affiliates beneficially owned and were entitled to vote an aggregate of 8,625,000 Founder Shares and 849,000 Private Shares held by the Sponsor and the officers and directors of AAM, representing approximately 21.54% of AAM’s issued and outstanding Ordinary Shares. Accordingly, if all outstanding Ordinary Shares are present at the Extraordinary General Meeting, then in addition to the Founder Shares, the Company will need 19,842,001 Public Shares, or 57.51% of the outstanding Public Shares, to vote in favor of the Extension Amendment Proposal to approve such proposal. Approval of the Trust Agreement Amendment Proposal requires pursuant to the Trust Agreement, the affirmative vote of at least two-thirds (2/3) of the then outstanding Ordinary Shares which are represented in person or by proxy and are voted at a general meeting of the Company, voting together as a single class.

To approve the Adjournment Proposal, assuming all outstanding Ordinary Shares are present at the Extraordinary General Meeting, then in addition to the Founder Shares, the Company will need 12,513,001 Public Shares, or 36.27% of the Public Shares, to vote in favor of the Adjournment Proposal to approve such proposal. The Adjournment Proposal will only be put forth for a vote if there are not sufficient votes to approve the Extension Amendment Proposal or the Trust Agreement Amendment Proposal at the Extraordinary General Meeting.”

The paragraph under “Questions and Answers About the Extraordinary General Meeting — How are votes counted?” is hereby amended and restated as follows:

Votes will be counted by the inspector of election appointed for the Extraordinary General Meeting, who will separately count “FOR” and “AGAINST” votes, “ABSTAIN” and broker non-votes. The Extension Amendment Proposal requires a special resolution under Cayman Islands law, being the affirmative vote of the holders of at least two-thirds (2/3) of the issued and outstanding Ordinary Shares entitled to vote and who, being present in person or represented by proxy at the Extraordinary General Meeting or any adjournment thereof, vote on such matter. Approval of the Trust Agreement Amendment Proposal requires pursuant to the Trust Agreement, the affirmative vote of at least two-thirds (2/3) of the then outstanding Ordinary Shares which are represented in person or by proxy and are voted at a general meeting of the Company, voting together as a single class. Approval of the Adjournment Proposal requires an ordinary resolution under Cayman Islands law, being the affirmative vote of the holders of at least a simple majority of the issued and outstanding Ordinary Shares entitled to vote and who, being present in person or represented by proxy at the Extraordinary General Meeting or any adjournment thereof, vote on such matter. With respect to the Extension Amendment Proposal, the Trust Agreement Amendment Proposal and the Adjournment Proposal, abstentions and broker non-votes will have no effect on outcome of any proposal brought before the Extraordinary General Meeting.

The paragraphs under “Extraordinary General Meeting of AAM — Quorum and Required Vote for Proposals” is hereby amended and restated as follows:

“The approval of the Extension Amendment Proposal requires a special resolution under Cayman Islands law, being the affirmative vote of the holders of at least two-thirds (2/3) of the issued and outstanding Ordinary Shares entitled to vote and who, being present in person or represented by proxy at the Extraordinary General Meeting or any adjournment thereof, vote on such matter.

On the Record Date, the Sponsor, AAM’s directors, officers and its initial shareholders and their respective affiliates beneficially owned and were entitled to vote an aggregate of 8,625,000 Founder Shares and 849,000 Private Shares held by the Sponsor and the officers and directors of AAM, representing approximately 26.80% of AAM’s issued and outstanding Ordinary Shares. Accordingly, if all outstanding Ordinary Shares are present at the Extraordinary General Meeting, then in addition to the Founder Shares, the Company will need 19,842,001 Public Shares, or 57.51% of the outstanding Public Shares, to vote in favor of the Extension Amendment Proposal to approve such proposal. Approval of the Trust Agreement Amendment Proposal requires pursuant to the Trust Agreement, the affirmative vote of at least two-thirds (2/3) of the then outstanding Ordinary Shares which are represented in person or by proxy and are voted at a general meeting of the Company, voting together as a single class.

The Adjournment Proposal will only be put forth for a vote if there are not sufficient votes to approve the Extension Amendment Proposal or the Trust Agreement Amendment Proposal at the Extraordinary General Meeting.”
