Dear Mr. Jiang:

This agreement (the “Agreement”) constitutes the agreement between D. Boral Capital LLC (“D. Boral”), uSmart Securities Limited (“uSmart,” together with D. Boral, the “Placement Agents”) and Neo-Concept International Group Holdings Limited, a Cayman Islands exempted company limited by shares (the “Company”), pursuant to which D. Boral shall serve as the lead placement agent for the Company, and uSmart shall serve as the joint placement agent for the Company, on a “reasonable best efforts” basis, in connection with the proposed placement (the “Placement”) of up to 14,850,000 Class A ordinary shares (the “Securities”) of par value US$0.0003125 (each, a “Class A Ordinary Share”). The terms of the Placement and the Securities shall be mutually agreed upon by the Company and the purchasers (each, a “Purchaser” and collectively, the “Purchasers”) and nothing herein constitutes that the Placement Agents would have the power or authority to bind the Company or any Purchaser or an obligation for the Company to issue any Securities or complete the Placement. This Agreement and the documents executed and delivered by the Company and the Purchasers in connection with the Placement, including but not limited to the Purchase Agreement (as defined below) shall be collectively referred to herein as the “Transaction Documents.” The date of the pricing of the Placement shall be referred to herein as the “Pricing Date.” The date of the closing of the Placement shall be referred to herein as the “Closing Date.” The Company expressly acknowledges and agrees that the Placement Agents’ obligations hereunder are on a reasonable best efforts basis only and that the execution of this Agreement does not constitute a commitment by the Placement Agents to purchase the Securities and does not ensure the successful placement of the Securities or any portion thereof or the success of the Placement Agents with respect to securing any other financing on behalf of the Company. The activities of uSmart in the United States will be chaperoned by D. Boral pursuant to Rule 15a-6 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”). With the prior written consent of the Company, the Placement Agents may retain other brokers or dealers to act as sub-agents or selected-dealers on its behalf in connection with the Placement. The sale of the Securities to any Purchaser may be evidenced by a securities purchase agreement (the “Purchase Agreement”) between the Company and such Purchaser in a form reasonably acceptable to the Company and the Placement Agents. Capitalized terms that are not otherwise defined herein have the meanings given to such terms in the Purchase Agreement. Prior to the signing of any Purchase Agreement, officers of the Company will be available to answer inquiries from prospective Purchasers.

In addition to the foregoing, the Company represents and warrants that:

The Company has filed with the U.S. Securities and Exchange Commission (the “Commission”), a registration statement, and any amendment or amendments thereto, on Form F-1 (File No. 333-288993), including any related prospectus or prospectuses for the registration of the Class A Ordinary Shares under the Securities Act of 1933, as amended (the “Securities Act”), which registration statement and amendment or amendments have been prepared by the Company in all material respects in conformity with the requirements of the Securities Act and the rules and regulations of the Commission under the Securities Act (the “Securities Act Regulations”) and will contain all material statements that are required to be stated therein in accordance with the Securities Act and the Securities Act Regulations. Except as the context may otherwise require, such registration statement, as amended, on file with the Commission at the time the registration statement became effective (including the Preliminary Prospectus included in the registration statement, financial statements, schedules, exhibits, and all other documents filed as a part thereof and all information deemed to be a part thereof as of the Effective Date pursuant to paragraph (b) of Rule 430A of the Securities Act Regulations (the “Rule 430A Information”)), is referred to herein as the “Registration Statement.” If the Company files any registration statement pursuant to Rule 462(b) of the Securities Act Regulations, then after such filing, the term “Registration Statement” shall include such registration statement filed pursuant to Rule 462(b). The Registration Statement was declared effective by the Commission September 30, 2025.

Each prospectus used prior to the Registration Statement being declared effective by the Commission, and each prospectus that omitted the Rule 430A Information that was used after being declared effective and prior to the execution and delivery of this Agreement is herein called a “Preliminary Prospectus.” The Preliminary Prospectus, subject to completion, dated January 16, 2026 that was included in the Registration Statement immediately prior to the applicable time, which means 5:30 p.m., Eastern Time, on the date of this Agreement, is hereinafter called the “Pricing Prospectus.” The final prospectus in the form first furnished to the Placement Agents for use in the Placement is hereinafter called the “Prospectus.” Any reference to the “most recent Preliminary Prospectus” shall be deemed to refer to the latest Preliminary Prospectus included in the Registration Statement. All references in this Agreement to financial statements and schedules and other information which is “contained,” “included,” “described,” “referenced,” “set forth” or “stated” in the Registration Statement, the Preliminary Prospectus, the Pricing Prospectus and the Prospectus (and all other references of like import) shall be deemed to mean and include all such financial statements and schedules and other information which is or is deemed to be incorporated by reference in the Registration Statement, the Preliminary Prospectus or the Prospectus, as the case may be.

This Agreement (including the attached Indemnification Provisions) together with the Engagement Letter embodies the entire agreement and understanding between the parties hereto, and supersedes all prior agreements and understandings, relating to the subject matter hereof. If any provision of this Agreement is determined to be invalid or unenforceable in any respect, such determination will not affect such provision in any other respect or any other provision of this Agreement, which will remain in full force and effect, and that the obligations set forth in Sections 5 through 17 of the Engagement Letter and Annex A to this Agreement shall survive termination. This Agreement may not be amended or otherwise modified or waived except by an instrument in writing signed by both Placement Agents and the Company. The representations, warranties, agreements and covenants contained herein shall survive the closing of the Placement and delivery of the Securities. This Agreement may be executed in two or more counterparts, all of which when taken together shall be considered one and the same agreement and shall become effective when counterparts have been signed by each party and delivered to the other party, it being understood that both parties need not sign the same counterpart. In the event that any signature is delivered by facsimile transmission or a .pdf format file, such signature shall create a valid and binding obligation of the party executing (or on whose behalf such signature is executed) with the same force and effect as if such facsimile or .pdf signature page were an original thereof.

SECTION 14. CONFIDENTIALITY. The Placement Agents (i) will keep the Confidential Information (as defined below) confidential and will not (except as required by applicable law or stock exchange requirement, regulation or legal process (“Legal Requirement”), without the Company’s prior written consent, disclose to any person any Confidential Information, and (ii) will not use any Confidential Information other than in connection with the Placement. The Placement Agents further agree, severally and not jointly, to disclose the Confidential Information only to its Representatives (as defined below) who need to know the Confidential Information for the purpose of the Placement, and who are informed by the Placement Agents of the confidential nature of the Confidential Information. The term “Confidential Information” shall mean, all confidential, proprietary and non-public information (whether written, oral or electronic communications) furnished by the Company to a Placement Agent or its Representatives in connection with such Placement Agent’s evaluation of the Placement. The term “Confidential Information” will not, however, include information which (i) is or becomes publicly available other than as a result of a disclosure by a Placement Agent or its Representatives in violation of this Agreement, (ii) is or becomes available to a Placement Agent or any of its Representatives on a non-confidential basis from a third-party who, to such Placement Agent’s and its Representatives’ knowledge, as applicable, is not bound by obligations of confidentiality to the Company with respect to such information, (iii) is known to a Placement Agent or any of its Representatives prior to disclosure by the Company or any of its Representatives from a source not bound by obligations of confidentiality to the Company with respect to such information, or (iv) is or has been independently developed by a Placement Agent and/or the Representatives without use of any Confidential Information furnished to it by the Company. The term “Representatives” shall mean a Placement Agent’s directors, board committees, officers, employees, financial advisors, attorneys and accountants. This provision shall be in full force until the earlier of (a) the date that the Confidential Information ceases to be confidential and (b) two (2) years from the date hereof. Notwithstanding any of the foregoing, in the event that the Placement Agents or any of their respective Representatives are required by Legal Requirement to disclose any of the Confidential Information, such Placement Agent and their respective Representatives will notify the Company in writing, as promptly as practicable, prior to disclosure of such information, and furnish only that portion of the Confidential Information which such Placement Agent or their respective Representative, as applicable, is required to disclose by Legal Requirement as advised by counsel, and will use reasonable efforts to obtain reliable assurance that confidential treatment will be accorded the Confidential Information so disclosed.

SECTION 15. NOTICES. Any and all notices or other communications or deliveries required or permitted to be provided hereunder shall be in writing and shall be deemed given and effective on the earliest of (a) the date of transmission, if such notice or communication is sent to the email address specified on the signature pages attached hereto prior to 6:30 p.m. (New York City time) on a business day, (b) the next business day after the date of transmission, if such notice or communication is sent to the email address on the signature pages attached hereto on a day that is not a business day or later than 6:30 p.m. (New York City time) on any business day, (c) the third business day following the date of mailing, if sent by U.S. internationally recognized air courier service, or (d) upon actual receipt by the party to whom such notice is required to be given. The address for such notices and communications shall be as set forth on the signature pages hereto.

SECTION 16. PRESS ANNOUNCEMENTS. The Company agrees that the Placement Agents shall, from and after any public announcement of the Closing, have the right to reference the Placement and the Placement Agents’ role in connection therewith in the Placement Agents’ marketing materials and on its website and to place advertisements in financial and other newspapers and journals, in each case at its own expense.

SECTION 17. LIMITATION OF LIABILITY. In no event shall the Placement Agents or any of their affiliates, directors, officers, employees, or controlling persons (within the meaning of Section 15 of the Securities Act, or Section 20 of the Exchange Act) be liable to the Company for any incidental, indirect, special or consequential damages (including lost profits) arising out of or in connection with this Agreement, whether or not such party was advised of the possibility of such damages. The liability of the Placement Agents and such other persons hereunder shall in no event exceed the aggregate amount of fees actually received by the Placement Agents pursuant to this Agreement (excluding any reimbursable expenses).

ANNEX A:

INDEMNIFICATION PROVISIONS

The Company agrees to indemnify and hold harmless the Placement Agents and their affiliates and their respective present and former directors, officers, employees, agents and controlling persons (each such person, including the Placement Agents, an “Indemnified Party”) from and against any losses, claims, damages and liabilities, joint or several (collectively, “Damages”), to which such Indemnified Party may become subject in connection with, relating to or arising from any transaction contemplated by this Agreement or the engagement of or performance of services by an Indemnified Party hereunder, and will reimburse each Indemnified Party for all out-of-pocket fees and expenses (“Expenses”), including the reasonable fees and expenses of counsel, as they are incurred in connection with investigating, preparing, pursuing or defending any threatened or pending subpoena, claim, action, proceeding or investigation (“Proceedings”) arising therefrom, whether or not any Indemnified Party is a formal party to such Proceeding; provided, that the Company will not be liable to any Indemnified Party to the extent that any Damages are found in a final non-appealable judgment by a court of competent jurisdiction to have resulted solely from the bad faith, gross negligence or willful misconduct of the Indemnified Party. No Indemnified Party will have any liability (whether direct or indirect, in contract, tort or otherwise) to the Company or any person asserting claims on behalf of the Company arising out of or in connection with any transactions contemplated by this Agreement or the engagement of or performance of services by any Indemnified Party hereunder except to the extent that the Company incurs Damages that are found in a final non-appealable judgment by a court of competent jurisdiction to have resulted solely from the bad faith, gross negligence or willful misconduct of the Indemnified Party.

If for any reason other than in accordance with the previous paragraph of this Annex A, the foregoing indemnity is unavailable to an Indemnified Party or insufficient to hold an Indemnified Party harmless, then the Company will contribute to the amount paid or payable by an Indemnified Party for Damages and Expenses related thereto in such proportion as is appropriate to reflect the relative benefits to the Company and/or its shareholders on the one hand, and the Placement Agents on the other hand, in connection with the matters covered by this Agreement or, if the foregoing allocation is not permitted by applicable law, not only such relative benefits but also the relative faults of such parties as well as any relevant equitable considerations. The Company agrees that for purposes of this paragraph the relative benefits to the Company and/or its shareholders and the Placement Agents in connection with the matters covered by this Agreement will be deemed to be in the same proportion that the total value paid or received or to be paid or received by the Company and/or its shareholders in connection with the transactions contemplated by this Agreement, whether or not consummated, bears to the fees paid to the Placement Agents under this Agreement; provided, that in no event will the total contribution of all Indemnified Parties to all such Damages and Expenses exceed the amount of fees actually received and retained by the Placement Agents under this Agreement (excluding any amounts received by the Placement Agents as reimbursement of expenses). Relative fault shall be determined by reference to, among other things, whether any alleged untrue statement or omission or any alleged conduct relates to information provided by the Company or other conduct by the Company (or its employees or other agents) on the one hand, or by the Placement Agents, on the other hand.

No Indemnified Party will agree to settle any Proceeding and seek indemnification or reimbursement hereunder unless such Indemnified Party obtained the Company’s consent (which consent will not be unreasonably withheld) to such settlement. The Company agrees not to enter into any waiver, release or settlement of any Proceeding (whether or not any Indemnified Party is a party thereto) in respect of which indemnification may be sought hereunder without the prior written consent of the Placement Agents (which consent will not be unreasonably withheld), unless such waiver, release or settlement (i) includes an unconditional release of each Indemnified Party from all liability arising out of such Proceeding, (ii) does not contain any factual or legal admission by or with respect to any Indemnified Party or any adverse statement with respect to the character, professionalism, expertise or reputation of any Indemnified Party or any action or inaction of any Indemnified Party and (iii) does not preclude or purport to preclude the future business activities of any Indemnified Person.

In addition to any rights of indemnification or contribution set forth above, the Company agrees to reimburse each Indemnified Party for all out-of-pocket costs and expenses as they are incurred (including, without limitation, the reasonable fees and expenses of outside counsel) in connection with investigating, preparing or settling any Proceeding involving the enforcement of this Agreement or this Annex A.

The indemnity, reimbursement and contribution obligations of the Company are in addition to any liability that the Company may have at common law or otherwise to any Indemnified Party and will be binding upon and inure to the benefit of any successors, assigns, heirs and personal representatives of the Company or an Indemnified Party. The provisions of this Annex will survive the modification, expiration or termination of this Agreement.

Ladies and Gentlemen:

The undersigned, a holder of securities of Neo-Concept International Group Holdings Limited, a Cayman islands company (the “Company”), understands that you are the placement agents (the “Placement Agents”) named in the placement agency agreement (the “Placement Agency Agreement”) entered into between the Placement Agent and the Company, providing for the placement (the “Placement”) of securities of the Company (the “Securities”) pursuant to a registration statement and related prospectuses and supplements thereto filed or to be filed with the U.S. Securities and Exchange Commission (the “SEC”).

In consideration of the Placement Agents’ agreement to proceed with the Placement of the Securities, and for other good and valuable consideration, receipt of which is hereby acknowledged, the undersigned hereby agrees, for the benefit of the Company and the Placement Agents that, without the prior written consent of the Placement Agents, the undersigned will not, during the period specified in the following paragraph (the “Lock-Up Period”), directly or indirectly, unless otherwise provided herein, (a) offer, sell, agree to offer or sell, solicit offers to purchase, convert, exercise, exchange, grant any call option or purchase any put option with respect to, pledge, encumber, assign, borrow or otherwise dispose of or transfer (each a “Transfer”) any Relevant Security (as defined below) or otherwise publicly disclose the intention to do so, or (b) establish or increase any “put equivalent position” or liquidate or decrease any “call equivalent position” (in each case within the meaning of Section 16 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”) and the rules and regulations thereunder) with respect to any Relevant Security or otherwise enter into any swap, derivative or other transaction or arrangement that Transfers to another, in whole or in part, any economic consequence of ownership of a Relevant Security, whether or not such transaction is to be settled by the delivery of Relevant Securities, other securities, cash or other consideration, or otherwise publicly disclose the intention to do so. As used herein, the term “Relevant Security” means any Class A Ordinary Share, par value US$0.0003125, of the Company (“Shares”), warrant to purchase Shares or any other security of the Company or any other entity that is convertible into, or exercisable or exchangeable for, Shares or any other equity security of the Company, in each case owned beneficially or otherwise by the undersigned on the date set forth on the front cover of the final prospectus supplement used in connection with the Placement of the Securities (the “Effective Date”) or acquired by the undersigned during the Lock-Up Period, including, for the avoidance of doubt, any Relevant Security acquired by the Undersigned in the Placement.

The Lock-Up Period will commence on the date of this Lock-up Agreement and continue and include the date that is sixty (60) days after the closing of the Placement.

In addition, the undersigned further agrees that, without the prior written consent of the Placement Agents, during the Lock-Up Period the undersigned will not: (i) file or participate in the filing with the SEC of any registration statement or circulate or participate in the circulation of any preliminary or final prospectus or other disclosure document, in each case with respect to any proposed offering or sale of a Relevant Security except as required by the terms of the Placement Agency Agreement, the Purchase Agreement and the Securities subject to the Placement, or (ii) exercise any rights the undersigned may have to require registration with the SEC of any proposed offering or sale of a Relevant Security.

In furtherance of the undersigned’s obligations hereunder, the undersigned hereby authorizes the Company during the Lock-Up Period to cause any transfer agent for the Relevant Securities to decline to transfer, and to note stop transfer restrictions on the stock register and other records relating to, Relevant Securities for which the undersigned is the record owner and the transfer of which would be a violation of this Lock-Up Agreement and, in the case of Relevant Securities for which the undersigned is the beneficial but not the record owner, agrees that during the Lock-Up Period it will cause the record owner to cause the relevant transfer agent to decline to transfer, and to note stop transfer restrictions on the stock register and other records relating to, such Relevant Securities to the extent such transfer would be a violation of this Lock-Up Agreement.

Notwithstanding the foregoing, the undersigned may transfer the undersigned’s Relevant Securities:

provided, that (A) such transfer shall not involve a disposition for value, (B) the transferee agrees in writing with the Placement Agents and the Company to be bound by the terms of this Lock-Up Agreement, and (C) such transfer would not require any filing under Section 16(a) of the Exchange Act and no such filing is voluntarily made. Moreover, the undersigned shall be permitted to establish a trading plan pursuant to Rule 10b5-1 under the Exchange Act for the transfer of Relevant Securities, provided that (i) such plan does not provide for the transfer of Relevant Securities during the Lock-Up Period and (ii) to the extent a public announcement or filing under the Exchange Act, if any, is required of or voluntarily made by or on behalf of the undersigned or the Company regarding the establishment of such plan, such public announcement or filing shall include a statement to the effect that no transfer of Relevant Securities may be made under such plan during the Lock-Up Period.

For purposes of this Lock-Up Agreement, “immediate family” shall mean any relationship by blood, marriage or adoption, not more remote than first cousin.

The undersigned hereby represents and warrants that the undersigned has full power and authority to enter into this Lock-Up Agreement and that this Lock-Up Agreement has been duly authorized (if the undersigned is not a natural person) and constitutes the legal, valid and binding obligation of the undersigned, enforceable in accordance with its terms. Upon request, the undersigned will execute any additional documents necessary in connection with the enforcement hereof. Any obligations of the undersigned shall be binding upon the successors and assigns of the undersigned from the date of this Lock-Up Agreement.

The undersigned understands that, if the Placement Agency Agreement (other than the provisions thereof which survive termination) shall terminate or be terminated prior to payment for and delivery of the Securities to be sold thereunder, the undersigned shall be released from all obligations under this Lock-Up Agreement.

The undersigned, whether or not participating in the Placement, understands that the Placement Agents are proceeding with the Placement in reliance upon this Lock-Up Agreement.
