AMENDMENT AND SUPPLEMENT TO THE PROXY STATEMENT

The following disclosures (the "Supplemental Disclosures") in this Current Report on Form 8-K supplement, and should be read in conjunction with, the disclosures contained in the Company's definitive proxy statement (as the same may be amended or supplemented, the "Proxy Statement"), filed with the Securities and Exchange Commission (the "SEC") on December 1, 2025, in connection with the 2025 Annual Meeting of Stockholders (the "Annual Meeting") of Foxx Development Holdings, Inc. (the "Company"), which will be held on December 22, 2025. To the extent the information set forth herein differs from or updates information contained in the Proxy Statement, the information set forth herein shall supersede or supplement the information in the Proxy Statement, which shall be read in its entirety. All other information in the Proxy Statement remains unchanged.

On November 19, 2025, 182,214 shares of common stock (the "Incentive Shares") previously granted to 15 directors, officers or employees of the Company under the 2024 Equity Incentive Plan became fully vested. On December 4, 2025, the transfer agent of the Company, Vstock Transfer LLC, completed the processing of the issuance of the Incentive Shares. As the Incentive Shares were issued as of November 19, 2025, the holders thereof would be entitled to vote as of the record date for the Annual Meeting, which is November 28, 2025 (the "Record Date").

The purpose of the Supplemental Disclosures is to update the total outstanding shares of common stock, par value $0.0001 per share, of the Company ("Common Stock") as of the Record Date, and the relevant disclosure in the Proxy Statement relating to the total outstanding shares of Common Stock. In addition, the Supplemental Disclosures also disclose the age of Ms. Michelle Jie Shen, a director nominee. Terms used herein, unless otherwise defined, have the meanings set forth in the Proxy Statement.

Amendment to Page 2: the Questions and Answers About the Annual Meeting

Q: Who is entitled to vote at the Annual Meeting?

A: Holders of record of Common Stock at the close of business on the Record Date are entitled to notice of and to vote at the Annual Meeting or any adjournment or postponement of the Annual Meeting. As of the Record Date, we had issued and outstanding 7,058,727 shares of Common Stock which were owned by 28 stockholders of record.

Amendment to Page 4: the Annual Meeting - Record Date and Voting Power

Our Board fixed the close of business on November 28, 2025, as the record date for the determination of the outstanding shares of Common Stock entitled to notice of, and to vote on, the matters presented at the Annual Meeting. As of the Record Date, there were an aggregate of 7,058,727 shares of Common Stock outstanding, with each share of Common Stock entitling the holder thereof to one vote.

Amendment to Page 7: Proposal 1. Election of Directors - Nominees for Election as Directors

Ms. Michelle Jie Shen is 50 years old.

Amendment to Page 12: Beneficial Ownership and Other Matters

The table below provides certain information about beneficial ownership of Common Stock as of the Record Date with respect to: (i) each person, or group of affiliated persons, who is known to the Company to own more than five percent (5%) of the shares of Common Stock outstanding; (ii) each of the Company's directors; (iii) each of the Company's executive officers; and (iv) all of the Company's directors and executive officers as a group.

Except as otherwise noted, to the knowledge of the Company, all persons listed below have sole voting and dispositive power with respect to all shares of Common Stock they beneficially own, except to the extent authority is shared by spouses under applicable law. The applicable percentage of beneficial ownership is based on 7,058,727 shares of Common Stock outstanding as of the Record Date. In computing the number of shares of Common Stock beneficially owned by a person and the applicable percentage of beneficial ownership for that person, we deemed beneficially owned those outstanding shares of Common Stock underlying options held by that person that are currently exercisable or exercisable within sixty (60) days of the Record Date. We did not deem these shares beneficially owned, however, for the purpose of computing the percentage of beneficial ownership for any other person.

Unless otherwise indicated, the address of each stockholder is in care of Foxx Development Holdings Inc., 15375 Barranca Parkway C106, Irvine, CA 92618.
