Item 3. Incorporation of Documents by Reference.

The following documents, which have been filed or furnished by IOTHREE LIMITED (the “Registrant”) with the Commission, are incorporated in this Registration Statement by reference:

(1) The Registrant’s Annual Report on Form 20-F for the fiscal year ended March 31, 2025, filed with the Commission on June 30, 2025, as amended by Amendment No. 1 filed with the Commission on August 6, 2025;

(3) The description of the Registrant’s ordinary shares, of par value of $0.00625 each, contained in the Registrant’s registration statement on Form 8-A12B filed on April 9, 2025 pursuant to Section 12(b) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”) including any amendment or reports filed hereafter for the purpose of updating such description.

All documents filed with the Commission pursuant to Sections 13(a), 13(c), 14 and 15(d) of the Exchange Act after the date of this Registration Statement and prior to the filing of a post-effective amendment to this Registration Statement which indicates that all of the securities offered hereby have been sold or which deregisters all of the securities covered hereby then remaining unsold, shall also be deemed to be incorporated by reference into this Registration Statement and to be a part hereof from the date of the filing of such documents; provided, however, that documents or information deemed to have been furnished and not filed in accordance with the rules of the Commission shall not be deemed incorporated by reference into this Registration Statement.

Any statement incorporated by reference herein shall be deemed to be modified or superseded for purposes of this Registration Statement to the extent that a statement contained herein or in any other subsequently filed document that also is or is deemed to be incorporated by reference herein modifies or supersedes such statement. Any statement so modified or superseded shall not be deemed, except as so modified or superseded, to constitute a part of this Registration Statement.

Item 4. Description of Securities.

Not applicable.

Item 5. Interests of Named Experts and Counsel.

Not applicable.

Item 6. Indemnification of Directors and Officers.

Cayman Islands law does not limit the extent to which a company’s memorandum and articles of association may provide for indemnification of officers and directors, except to the extent any such provision may be held by the Cayman Islands courts to be contrary to public policy, such as to provide indemnification against civil fraud or the consequences of committing a crime. The amended and restated memorandum and articles of association of the Registrant provide that the Registrant shall indemnify its directors and officers, and their personal representatives, against all actions, proceedings, costs, charges, expenses, losses, damages or liabilities incurred or sustained by such persons, other than by reason of such person’s dishonesty, willful default or fraud, in or about the conduct of the Registrant’s business or affairs (including as a result of any mistake of judgment) or in the execution or discharge of his or her duties, powers, authorities or discretions, including without prejudice to the generality of the foregoing, any costs, expenses, losses or liabilities incurred by such person in defending (whether successfully or otherwise) any civil proceedings concerning the Registrant or its affairs in any court whether in the Cayman Islands or elsewhere.

The Registrant has entered into indemnification agreements with the Registrant’s directors and executive officers which provide, among other things, that the Registrant will indemnify its directors and executive officers to the fullest extent permitted by Cayman Islands law from and against all liabilities, costs, charges and expenses incurred as a result of directors and executive officers actions in the exercise of their duties as a director or officer.

The Registrant has purchased directors and officers (D&O) liability insurance, covering the period from April 10, 2025 to April 9, 2026. This insurance provides coverage for claims made against its directors, officers and certain employees arising from alleged wrongful acts in their official capacities. It also includes reimbursements to the Registrant when it is required or permitted to indemnify those individuals, as well as coverage for reasonable expenses incurred in preparing self-reports or responding to regulatory inquiries.

II-1

Insofar as indemnification for liabilities arising under the Securities Act may be permitted to the Registrant’s directors, officers or persons controlling the Registrant under the foregoing provisions, we have been informed that in the opinion of the Commission such indemnification is against public policy as expressed in the Securities Act and is therefore unenforceable.

Item 7. Exemption from Registration Claimed.

Not Applicable.

Item 9. Undertakings.

(a) The undersigned registrant hereby undertakes:

(1) To file, during any period in which offers or sales are being made, a post-effective amendment to this Registration Statement:

(i) To include any prospectus required by Section 10(a)(3) of the Securities Act;

(ii) To reflect in the prospectus any facts or events arising after the effective date of this Registration Statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in this Registration Statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high and of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than 20 percent change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective Registration Statement; and

(iii) To include any additional or changed material information with respect to the plan of distribution not previously disclosed in this Registration Statement;

II-2

provided, however, that the undertakings set forth in paragraphs (a)(1)(i) and (a)(1)(ii) above do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in periodic reports filed with or furnished to the Commission by the registrant pursuant to Section 13 or 15(d) of the Exchange Act that are incorporated by reference in this Registration Statement.

(2) That, for the purpose of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

(b) The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act, each filing of the registrant’s annual report pursuant to Section 13(a) or 15(d) of the Exchange Act (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to Section 15(d) of the Exchange Act) that is incorporated by reference in this Registration Statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(c) Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Commission such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.
