Units

Rights

From time to time, we may offer, issue and sell up to US$30,000,000 of any combination of the securities described in this prospectus in one or more offerings. We may also offer securities as may be issuable upon conversion, redemption, repurchase, exchange or exercise of any securities registered hereunder, including any applicable antidilution provisions.

This prospectus provides a general description of the securities we may offer. Each time we offer securities, we will provide specific terms of the securities offered in a supplement to this prospectus. We may also authorize one or more free writing prospectuses to be provided to you in connection with these offerings. The prospectus supplement and any related free writing prospectus may also add, update or change information contained in this prospectus. You should carefully read this prospectus, the applicable prospectus supplement and any related free writing prospectus, as well as any documents incorporated by reference, before you invest in any of the securities being offered.

This prospectus may not be used to sell our securities unless accompanied by a prospectus supplement. The prospectus supplement or any related free writing prospectus may also add to, update, supplement or clarify information contained in this prospectus.

Pursuant to General Instruction I.B.5. of Form F-3, in no event will we sell the securities covered hereby in a public primary offering with a value exceeding more than one-third of the aggregate market value of our Ordinary Shares in any 12-month period so long as the aggregate market value of our outstanding Ordinary Shares held by non-affiliates remains below $75,000,000.

The aggregate market value of our outstanding voting and non-voting common equity held by non-affiliates is approximately $11,405,600 based on the closing price of $4.24 per ordinary share on August 12, 2026 and 2,690,000 Ordinary Shares held by non-affiliates. During the 12 calendar months prior to and including the date of this prospectus, we have not offered or sold any securities pursuant to General Instruction I.B.5 of Form F-3.

Our Ordinary Shares are listed on the NYSE American under the symbol “LUD.” The applicable prospectus supplement will contain information, where applicable, as to other listings, if any, on the NYSE American or other securities exchange of the securities covered by the prospectus supplement.

We are both an “emerging growth company” and a “foreign private issuer” under applicable U.S. Securities and Exchange Commission rules and as such are eligible for reduced public company disclosure requirements. See section titled “Prospectus Summary — Implications of Being an ‘Emerging Growth Company’ and a ‘Foreign Private Issuer’” for additional information.

We may sell these securities directly to investors, through agents designated from time to time or to or through underwriters or dealers. For additional information on the methods of sale, you should refer to the section entitled “Plan of Distribution” in this prospectus. If any underwriters are involved in the sale of any securities with respect to which this prospectus is being delivered, the names of such underwriters and any applicable commissions or discounts will be set forth in a prospectus supplement. The price to the public of such securities and the net proceeds we expect to receive from such sale will also be set forth in a prospectus supplement.

We are a Cayman Islands holding company without any operation and our operations are conducted by our wholly owned subsidiaries in China and Hong Kong and this structure involves unique risks to investors.

There are legal and operational risks associated with being based in and having all our operations in China and Hong Kong.

The PRC government initiated a series of regulatory actions and made a number of public statements on the regulation of business operations in certain areas in China, including cracking down on illegal activities in the securities market, enhancing supervision over China-based companies listed overseas using VIE structure, adopting new measures to extend the scope of cybersecurity reviews, and expanding the efforts in anti-monopoly enforcement. We do not believe that we are directly subject to these regulatory actions or statements, as we do not have a VIE structure and our business does not involve the collection of user data, implicate cybersecurity, or involve any other type of restricted industry. Since these statements and regulatory actions are new, it is highly uncertain how soon the legislative or administrative regulation making bodies will respond and what existing or new laws or regulations or detailed implementations and interpretations will be modified or promulgated, if any, or the potential impact such modified or new laws and regulations will have on our daily business operations or our ability to accept foreign investments and list on a U.S. exchange. Any change in foreign investment regulations, and other policies in China or related enforcement actions by China government could result in a material change in our operations and/or the value of the securities we are registering for sale and could significantly limit or completely hinder our ability to offer or continue to offer our Ordinary Shares to investors or cause the value of our Shares to significantly decline or be worthless.

The Chinese government recently took regulatory actions on certain U.S. listed Chinese companies and made statement that it will exert more oversight and control over offerings and listings by Chinese companies that are conducted overseas, such as those related to the use of variable interest entities and data security or anti-monopoly concerns. On July 10, 2021, the CAC issued a revised draft of the Cybersecurity Review Measures (“Revised Draft”), which required that, among others, in addition to an “operator of critical information infrastructure,” any “data processor” controlling personal information of no less than one million users that seeks to list in a foreign stock exchange should also be subject to cybersecurity review.

On December 28, 2021, the CAC, the National Development and Reform Commission (“NDRC”), and several other administrations jointly adopted and published the Measures for Cybersecurity Review (the “Measures”), which came into effect on February 15, 2022. The Measures reiterate that, if an “operator of critical information infrastructure” or “network platform operator” that is in possession of personal data of more than one million users intends to list in a foreign country, it must apply for a cybersecurity review. The Measures further elaborates the factors to be considered when assessing the national security risks of the relevant activities, including, among others, (i) the risk of core data, important data or a large amount of personal information being stolen, leaked, destroyed, and illegally used or exited the country; and (ii) the risk of critical information infrastructure, core data, important data or a large amount of personal information being affected, controlled, or maliciously used by foreign governments after listing abroad.

We do not currently expect the Measures to have an impact on our business or operations as we do not believe that Luda PRC, Lingding PRC, Huanguang PRC, Qiyu Tongda PRC and Mayi PRC are deemed to be an “operator of critical information infrastructure,” “data processor,” or “network platform operator” controlling personal information of no less than one million users, that are required to file for cybersecurity review before listing in the U.S., because (i) as of the date of this prospectus, we are required to collect and retain some basic information furnished by our customers. We have collected and stored personal information far less than one million users, suppliers and employees in accordance with prevailing business practices; (ii) we do not place any reliance on collection and processing of any personal information to maintain our business operation; and (iii) data processed in our business should not have a bearing on national security nor affect or may affect national security; as of the date of this prospectus, we has not been involved in any investigations on cybersecurity or data security initiated by related governmental regulatory authorities, and we have not received any inquiry, notice, warning, or sanction in such respect. Therefore, we are not covered by the permission and requirements from the CSRC nor CAC, and except for the permissions with minimal impact on the operations, we have received all necessary permissions to operate our business in China and no permission has been denied. We has received all necessary permissions required to obtain from PRC authorities to operate its current business in China or issue shares to foreign investors, including Business License, Customs Registration Certificate, Bank Account Open Permit and Approval regarding Environmental Protection.

On July 7, 2022, the CAC issued the Security Assessment Measures, which came into effect on September 1, 2022. The Security Assessment Measures provide that certain types of data processors transferring important data or personal information collected and generated during operations within the territory of the PRC to an overseas recipient must apply for security assessment of cross-border data transfer. In addition, on September 28, 2023, CAC published the Provisions on Regulating and Promoting Cross -border Data Transfer (Draft for Comments), or the Cross -border Data Transfer Provisions. The Cross-border Data Transfer Provisions provide certain exemptions from obligations under the circumstances of cross-border data transfer, including, among others, the obligations for data security assessment, concluding a standard contract for provision of personal information abroad or passing the certification for personal information protection. However, the Cross-border Data Transfer Provisions were released for public comment only and their provisions and anticipated adoption date are subject to changes with substantial uncertainty, and their interpretation and implementation remain uncertain.

On February 17, 2023, the CSRC issued the Trial Administrative Measures of Overseas Securities Offering and Listing by Domestic Enterprises, or the Trial Measures, which became effective on March 31, 2023. On the same date of the issuance of the Trial Measures, the CSRC circulated No.1 to No.5 Supporting Guidance Rules, the Notes on the Trial Measures, the Notice on Administration Arrangements for the Filing of Overseas Listings by Domestic Enterprises and the relevant CSRC Answers to Reporter Questions on the official website of the CSRC, or collectively, the Guidance Rules and Notice. The Trial Measures, together with the Guidance Rules and Notice, reiterate the basic supervision principles as reflected in the Draft Overseas Listing Regulations by providing substantially the same requirements for filings of overseas offering and listing by domestic companies, yet made the following updates compared to the and Draft Overseas Listing Regulations: (a) further clarification of the circumstances prohibiting overseas issuance and listing; (b) further clarification of the standard of indirect overseas listing under the principle of substance over form, and (c) adding more details of filing procedures and requirements by setting different filing requirements for different types of overseas offering and listing. Under the Trial Measures and the Guidance Rules and Notice, domestic companies conducting overseas securities offering and listing activities, either in direct or indirect form, shall complete filing procedures with the CSRC pursuant to the requirements of the Trial Measures within three working days following its submission of initial public offerings or listing application. The companies that have already been listed on overseas stock exchanges or have obtained the approval from overseas supervision administrations or stock exchanges for its offering and listing and will complete their overseas offering and listing prior to September 30, 2023 are not required to make immediate filings for its listing yet need to make filings for subsequent offerings in accordance with the Trial Measures. The companies that have already submitted an application for an initial public offering to overseas supervision administrations prior to the effective date of the Trial Measures but have not yet obtained the approval from overseas supervision administrations or stock exchanges for the offering and listing may arrange for the filing within a reasonable time period and should complete the filing procedure before such companies’ overseas issuance and listing.

On February 24, 2023, the CSRC, the Ministry of Finance, the National Administration of State Secrets Protection and National Archives Administration of China promulgated the Provisions on Strengthening Confidentiality and Archives Administration of Overseas Securities Offering and Listing by Domestic Companies, or the Archives Rules, which will come into force on March 31, 2023. According to the Archives Rules, domestic companies seeking for overseas offering and listing shall strictly comply with relevant laws and regulations of the PRC and the Archives Rules, enhance legal awareness of keeping state secrets and strengthening archives administration, establish a sound administration system of confidentiality and archives, and take necessary means to fulfill confidentiality and archives administration obligations. Such domestic companies shall not leak any state secret and working secret of government agencies, and shall not harm national security and public interest. In addition, a domestic company that plans to, either directly or through its overseas listed entity, publicly disclose or provide to relevant individuals or entities including securities companies, securities service providers and overseas regulators, any document and materials that contain state secrets or working secrets of government agencies, shall first obtain approval from competent authorities according to law, and file with the secrecy administrative department at the same level. Moreover, a domestic company that plans to, either directly or through its overseas listed entity, publicly disclose or provide to relevant individuals and entities including securities companies, securities service providers and overseas regulators, any other documents and materials that, if leaked, will be detrimental to national security or public interest, shall strictly fulfill relevant procedures stipulated by applicable national regulations. The Archives Rules also specify that a domestic company that provides accounting archives or copies of accounting archives to any entities including securities companies, securities service providers and overseas regulators and individuals shall fulfill due procedures in accordance with applicable national regulations.

Our operations are located in Hong Kong and the PRC. As such we are subject to Hong Kong laws and PRC laws relating to the collection, use, sharing, retention, security, and transfer of confidential and private information, such as personal information and other data. These laws apply not only to third-party transactions, but also other parties with which we have commercial relations. These laws continue to develop, and the PRC government may adopt other rules and restrictions in the future. Non-compliance with these laws could result in penalties or other significant legal liabilities.

We believe, that as of the date of this prospectus, we have obtained all necessary permissions for a domestic company in China to engage in similar businesses, and are not required to obtain other permissions by including the CSRC, CAC or any other PRC authorities for its operations or issue our Shares including the Shares being registered for sale to foreign investors under existing PRC laws and regulations, and have not received any requirement or were denied such permissions or approvals by any PRC authorities. According to the Measures, if an “operator of critical information infrastructure” or “network platform operator” that is in possession of personal data of more than one million users intends to list in a foreign country, it must apply for a cybersecurity review. The Measures further elaborates the factors to be considered when assessing the national security risks of the relevant activities, including, among others, (i) the risk of core data, important data or a large amount of personal information being stolen, leaked, destroyed, and illegally used or exited the country; and (ii) the risk of critical information infrastructure, core data, important data or a large amount of personal information being affected, controlled, or maliciously used by foreign governments after listing abroad. As of the date of this prospectus, neither the Company nor its PRC subsidiaries possesses a large amount of personal information in their business operations or is recognized as an “operator of critical information infrastructure” by any authentic authority. Therefore, we do not believe that our PRC subsidiaries are deemed to be an “operator of critical information infrastructure,” or “network platform operator” controlling personal information of no less than one million users. We are required to collect and retain some basic information furnished by our customers, suppliers and employees in accordance with prevailing business practices, but we do not handle personal and confidential data of more than 1,000 individuals in the ordinary course of business. As of the date of this prospectus, we have not been involved in any investigations on cybersecurity or data security initiated by related governmental regulatory authorities, and we have not received any inquiry, notice, warning, or sanction in such respect. We have received all necessary permissions required to obtain from PRC authorities to operate its current business in China or issue shares to foreign investors, including Business License, Customs Registration Certificate, Bank Account Open Permit and Approval regarding Environmental Protection.

Neither the Securities and Exchange Commission nor any other regulatory body has approved or disapproved of these securities or passed upon the adequacy or accuracy of this prospectus. Any representation to the contrary is a criminal offense.

Investing in the shares involves risks. See section titled “Risk Factors” on page 7 of this prospectus.

Corporate History and Structure

We are a manufacturer and trader of stainless steel and carbon steel flanges and fittings products. Our history began with Luda HK which was incorporated in Hong Kong in 2004 and is principally engaged in the trading of steel flanges and fittings. Our Company is a holding company incorporated under the laws of the Cayman Islands with limited liability on October 21, 2021. Prior to the incorporation of our Company, the principal operations are carried out through Luda HK and Luda PRC which were founded by Mr. Ma Biu, our Controlling Shareholder. We have conducted a reorganization, primarily to facilitate our initial public offering, which was completed on December 19, 2023. On July 13, 2026 and July 14, 2026, we established Lingding PRC, Huanguang PRC, Qiyu Tongda PRC and Mayi PRC, which are indirect subsidiaries held by Luda PRC. The diagram below illustrates our corporate structure as of the date of this prospectus:

Cautionary Statement Regarding Holding Foreign Companies Accountable Act

Our Ordinary Shares may be prohibited from being traded on a national exchange under the Holding Foreign Companies Accountable Act (the “HFCA Act”) if the Public Company Accounting Oversight Board (“PCAOB”) is unable to inspect our auditors for two consecutive years. On December 23, 2022, the Accelerating Holding Foreign Companies Accountable Act (the “AHFCA Act”) was enacted, which amended the HFCA Act by requiring the SEC to prohibit an issuer’s securities from trading on any U.S. stock exchanges if its auditor is not subject to PCAOB inspections for two consecutive years instead of three. On December 29, 2022, a legislation entitled “Consolidated Appropriations Act, 2023” (the “Consolidated Appropriations Act”) was signed into law by President Biden, which contained, among other things, an identical provision to AHFCA Act and amended the HFCA Act by requiring the SEC to prohibit an issuer’s securities from trading on any U.S. stock exchanges if its auditor is not subject to PCAOB inspections for two consecutive years instead of three years. On December 16, 2021, the PCAOB issued a report on its determinations that it was unable to inspect or investigate completely PCAOB-registered public accounting firms headquartered in mainland China and in Hong Kong, because of positions taken by PRC authorities in those jurisdictions. The PCAOB made its determinations pursuant to PCAOB Rule 6100, which provides a framework for how the PCAOB fulfils its responsibilities under the HFCA. The report further listed in its Appendix A and Appendix B, Registered Public Accounting Firms Subject to the Mainland China Determination and Registered Public Accounting Firms Subject to the Hong Kong Determination, respectively. Our current and predecessor auditors, AOGB CPA Limited and ZH CPA, LLC, respectively, are headquartered in Hong Kong, China and Colorado respectively. They are both registered with the PCAOB and are subject to laws in the United States pursuant to which the PCAOB conducts regular inspections to assess our auditor’s compliance with the applicable professional standards. In addition, they did not appear as part of the PCAOB’s report of determinations under the lists in Appendix A or Appendix B of the report issued by the PCAOB on December 16, 2021. On August 26, 2022, the China Securities Regulatory Commission, or CSRC, the Ministry of Finance of the PRC, and the PCAOB signed a Statement of Protocol, or the Protocol, governing inspections and investigations of audit firms based in mainland China and Hong Kong and taking the first step toward opening access for the PCAOB to inspect and investigate registered public accounting firms headquartered in mainland China and Hong Kong. Pursuant to the Protocol, the PCAOB shall have independent discretion to select any issuer audits for inspection or investigation and has the unfettered ability to transfer information to the SEC. On December 15, 2022, the PCAOB announced that it was able to secure complete access to inspect and investigate PCAOB-registered public accounting firms headquartered in mainland China and Hong Kong in 2022, and the PCAOB Board vacated its previous determinations that the PCAOB was unable to inspect or investigate completely registered public accounting firms headquartered in mainland China and Hong Kong. However, whether the PCAOB will continue to be able to satisfactorily conduct inspections of PCAOB-registered public accounting firms headquartered in mainland China and Hong Kong is subject to uncertainty and depends on a number of factors out of our, and our auditor’s, control. The PCAOB is continuing to demand complete access in mainland China and Hong Kong moving forward and is already making plans to resume regular inspections in early 2023 and beyond, as well as to continue pursuing ongoing investigations and initiate new investigations as needed. The PCAOB has indicated that it will act immediately to consider the need to issue new determinations with the HFCA Act if needed. As a result, the time period before the Company’s securities may be prohibited from trading or delisted has been decreased accordingly. Notwithstanding the foregoing, in the event it is later determined that the PCAOB is unable to inspect or investigate completely our auditor, then such lack of inspection could cause our Ordinary Shares to be delisted from the stock exchange. The delisting of our Ordinary Shares, or the threat of their being delisted, may materially and adversely affect the value of your investment. See Item 3.D. “Risk Factors — Our Ordinary Shares may be delisted from a U.S. exchange and prohibited from being traded over-the-counter in the United States under the HFCA Act if the PCAOB determines in the future that it is unable to fully inspect or investigate our auditors. The delisting and cease of trading of our Ordinary Shares, or the threat of their being delisted or prohibited from being traded, may materially and adversely affect the value of your investment.”

Permission Required from Hong Kong Authorities

Hong Kong is a Special Administrative Region of the PRC, having its own governmental and legal system that is separate from mainland China, and as a result, has its own distinct rules and regulations. Luda HK is the holding company of Luda PRC and is an operating subsidiary acting as a trading company. Based on our understanding of the current Hong Kong laws, as of the date of this prospectus, we, including Luda HK, have received and obtained all requisite licenses, certificates, authorizations, permissions or approvals from the Hong Kong authorities to operate our business in Hong Kong, including but not limited to obtaining a relevant certificate of incorporation and business license, and that we, including Luda HK are not required to obtain any permission or approval from Hong Kong authorities to offer the shares of Luda Cayman to foreign investors. However, uncertainties still exist due to the possibility that laws, regulations, or policies in Hong Kong could change rapidly in the future. Should there be any change in applicable laws, regulations, or interpretations that we or any of our subsidiaries are required to obtain such permissions or approvals in the future, we will strive to comply with the then applicable laws, regulations, or interpretations. In the event that we, including Luda HK, (i) do not receive or fail to maintain such permissions or approvals in the future, (ii) inadvertently conclude that relevant licenses, certificates, authorizations, permissions or approvals were not required, or (iii) are required to obtain such licenses, certificates, authorizations, permissions or approvals in the future following applicable laws, regulations, or interpretation changes, any action taken by the Hong Kong government could significantly limit or completely hinder our operations and our ability to offer or continue to offer securities to investors and could cause the value of our securities to significantly decline or be worthless.

Permission Required from PRC Authorities

The PRC government has recently initiated a series of regulatory actions and made a number of public statements on the regulation over offerings of securities conducted overseas. On December 28, 2021, the Cyberspace Administration of China, National Development and Reform Commission, Ministry of Industry and Information Technology, The Ministry of Public Security, the Ministry of State Security, Ministry of Finance, Ministry of Commerce, People’s Bank of China, State Administration for Market Regulation, State Administration of Radio and Television, China Securities Regulatory Commission, State Secrecy Administration and State Cryptography Administration jointly promulgated the Measures for Cybersecurity Review (2021 Version, the “Measures”), which became effective on February 15, 2022. The Measures require that among other things, and in addition to any “operator of critical information infrastructure”, any “data processor” controlling personal information of no less than one million users (which to be further specified) which seeks to list in a foreign stock exchange should also be subject to cybersecurity review, and which the Measures further elaborate on the factors to be considered when assessing the national security risks of the relevant activities. As of the date of this prospectus, we are not subject to cybersecurity review with the CAC to conduct business operations in China, given that: (i) we do not operate any network platform or provide any network service for individual users, (ii) all the customers and suppliers of our PRC subsidiaries are enterprises, (iii) we are required to collect and retain some basic information furnished by our customers, suppliers and employees in accordance with prevailing business practices, but we do not possess a large amount of personal information in our business operations, (iv) we are not recognized as “operators of critical information infrastructure” by any authentic authority, (v) we have not been involved in any investigations on cybersecurity or data security initiated by related governmental regulatory authorities, nor have we received any inquiry, notice, warning, or sanction in such respect. Nevertheless, the Measures was recently adopted and the CAC Notice for Soliciting Public Comments on the Regulations for the Administration of Network Data Security (Exposure Draft) is in the process of being formulated and the interpretation and application of these regulations are evolving. We have been closely monitoring regulatory developments in mainland China regarding any necessary approvals from the CSRC, the CAC, or other PRC governmental authorities required for the conduct of our business operations and overseas listings.

If we or our PRC subsidiary (i) do not receive or maintain such permissions or approvals, (ii) inadvertently conclude that such permissions or approvals are not required, or (iii) applicable laws, regulations, or interpretations change and require us to obtain such permissions or approvals in the future, we may face sanctions by the CSRC, the CAC or other PRC regulatory agencies. These regulatory agencies may impose fines and penalties on our operations in China, limit our ability to pay dividends outside of China, limit our operations in China, delay or restrict the repatriation of the proceeds from overseas offering into China or take other actions that could have a material adverse effect on our business as well as the trading price of our Shares. We could be required to restructure our operations to comply with such regulations or potentially cease operations in the PRC entirely. The CSRC, the CAC or other PRC regulatory agencies also may take actions requiring us, or making it advisable for us, to halt overseas offering before settlement and delivery of our Shares. In addition, if the CSRC, the CAC or other regulatory PRC agencies later promulgate new rules requiring that we obtain their approvals for overseas offering, we may be unable to obtain a waiver of such approval requirements, if and when procedures are established to obtain such a waiver. Any action taken by the PRC government could significantly limit or completely hinder our operations in the PRC and our ability to offer or continue to offer securities to investors and could cause the value of such securities to significantly decline or be worthless.

Transfers of Cash To and From Our Subsidiaries

On January 8, 2024, May 6, 2024 and August 26, 2024, Luda Cayman paid dividend of RMB9,250,000, RMB5,700,000 and RMB9,000,000, respectively, to Diamond Horses Group Limited. We may declare or pay dividends in the foreseeable future. Any future determination related to our dividend policy will be made at the discretion of our board of directors after considering our financial condition, results of operations, capital requirements, contractual requirements, business prospects and other factors the board of directors deems relevant, and subject to the restrictions contained in any future financing instruments.

We are permitted under the laws of the Cayman Islands to provide funding to our Operating Subsidiaries through loans and/or capital contributions without restriction on the amount of the funds loaned or contributed.

Subject to Cayman Islands law, the Companies Act and our amended and restated memorandum and articles of association, our board of directors may declare dividends in any currency. Under the laws of the Cayman Islands, an exempted company incorporated in the Cayman Islands may pay a dividend out of profit and/or share premium account, provided that in no circumstances may a dividend be paid out of the share premium if this would result in the company being unable to pay its debts as they fall due in the ordinary course of business.

Under Hong Kong law, a Hong Kong company may only make a distribution out of profits available for distribution. There are no restrictions or limitations under the laws of Hong Kong imposed on the conversion of HK dollars into foreign currencies and the remittance of currencies out of Hong Kong, nor is there any restriction on foreign exchange to transfer cash between the Company and its subsidiaries, across borders and to U.S. investors, nor are there any restrictions or limitations on distributing earnings from our business and subsidiaries to the Company and U.S. investors.

Subject to PRC laws, payments of current account items, such as trade and service-related foreign exchange transactions, can be made in foreign currencies without prior approval from State Administration of Foreign Exchange or SAFE by complying with certain procedural requirements. By contrast, approval from or registration with appropriate governmental authorities is required where RMB is to be converted into foreign currency and remitted out of China to pay capital expenses such as profit distributions and the repayment of foreign currency-denominated loans.

Implications of Our Being an Emerging Growth Company

As a company with less than US$1.235 billion in revenue for our last fiscal year, we qualify as an “emerging growth company” pursuant to the Jumpstart Our Business Startups Act of 2012, or the JOBS Act. An emerging growth company may take advantage of specified reduced reporting and other requirements compared to those that are otherwise applicable generally to public companies. These provisions include exemption from the auditor attestation requirement under Section 404 of the Sarbanes-Oxley Act of 2002, or Section 404, in the assessment of the emerging growth company’s internal control over financial reporting. The JOBS Act also provides that an emerging growth company does not need to comply with any new or revised financial accounting standards until such date that a private company is otherwise required to comply with such new or revised accounting standards. We have elected to take advantage of the benefits of this extended transition period provided under the JOBS Act for complying with new or revised accounting standards. As a result, our operating results and financial statements may not be comparable to the operating results and financial statements of other companies who have adopted the new or revised accounting standards.

We will remain an emerging growth company until the earliest of (i) the last day of the fiscal year during which we have total annual gross revenue of at least US$1.235 billion; (ii) the last day of our fiscal year following the fifth anniversary of the completion of this offering; (iii) the date on which we have, during the preceding three-year period, issued more than US$1.0 billion in non-convertible debt; or (iv) the date on which we are deemed to be a “large accelerated filer” under the Securities Exchange Act of 1934, as amended, or the Exchange Act, which would occur if the market value of the Ordinary Shares that are held by non-affiliates exceeds US$700 million as of the last business day of our most recently completed second fiscal quarter. Once we cease to be an emerging growth company, we will not be entitled to the exemptions provided in the JOBS Act discussed above. We are an “emerging growth company” as the term is used in the JOBS Act and, as such, we are subject to certain reduced public company reporting requirements.

Implications of Being a Foreign Private Issuer

We are reporting under the Exchange Act as a non-U.S. company with foreign private issuer status. Even after we no longer qualify as an emerging growth company, as long as we qualify as a foreign private issuer under the Exchange Act, we will be exempt from certain provisions of the Exchange Act that are applicable to U.S. domestic public companies, including:

	●	we are permitted to follow certain home country corporate governance practices in lieu of certain requirements under the NYSE American corporate governance listing standards. This may afford less protection to holders of our Ordinary Shares than U.S. regulations;

	●	the sections of the Exchange Act regulating the solicitation of proxies, consents or authorizations in respect of a security registered under the Exchange Act;

	●	we are not subject to proxy rules and are not required to provide as many Exchange Act reports, or as frequently, as a domestic public company;

	●	we are not required to provide the same level of disclosure on certain issues, such as executive compensation;

●

we are exempt from provisions of Regulation FD aimed at preventing issuers from making selective disclosures of material information;

●

the sections of the Exchange Act requiring insiders to file public reports of their stock ownership and trading activities and liability for insiders who profit from trades made in a short period of time; and

●

the rules under the Exchange Act requiring the filing with the Securities and Exchange Commission, or the SEC, of quarterly reports on Form 10-Q containing unaudited financial and other specified information, or current reports on Form 8-K, upon the occurrence of specified significant events.

Both foreign private issuers and emerging growth companies are also exempt from certain more stringent executive compensation disclosure rules. Thus, even if we no longer qualify as an emerging growth company but remain a foreign private issuer, we will continue to be exempt from the more stringent compensation disclosures required of companies that are neither emerging growth companies nor foreign private issuers.

In addition, as a company incorporated in the Cayman Islands, we are permitted to adopt certain home country practices in relation to corporate governance matters that differ significantly from the corporate governance listing requirements of the NYSE American. These practices may afford less protection to shareholders than they would enjoy if we complied fully with corporate governance listing requirements of the NYSE American. Following this offering, we will rely on home country practice to be exempted from certain of the corporate governance requirements of the NYSE American, such that a majority of the directors on our board are not required to be independent directors.

Implications of Being a Controlled Company

We expect that Diamond Horses Group Limited will hold more than 50% of the aggregate voting power of our total issued and outstanding share capital following this offering and we will continue to be a controlled company pursuant to “controlled company” defined under the NYSE American Company Guide. Accordingly, we will be a controlled company under the NYSE American corporate governance rules. For so long as we are a controlled company under that definition, we are permitted to elect to rely, and may rely, on certain exemptions from corporate governance rules, including:

	●	an exemption from the rule that a majority of our board of directors must be independent directors;

	●	an exemption from the rule that the compensation of our chief executive officer must be determined or recommended solely by independent directors; and

	●	an exemption from the rule that our director nominees must be selected or recommended solely by independent directors.

As a result, you will not have the same protection afforded to shareholders of companies that are subject to these corporate governance requirements.

Although we do not intend to rely on the “controlled company” exemption under the NYSE American corporate governance rules, we could elect to rely on this exemption in the future. If we elected to rely on the “controlled company” exemption, a majority of the members of our board of directors might not be independent directors and our nominating and corporate governance and compensation committees might not consist entirely of independent directors upon closing of the Offering. Our status as a controlled company could cause our Ordinary Shares to look less attractive to certain investors or otherwise harm our trading price. As a result, the investors will not have the same protection afforded to shareholders of companies that are subject to these corporate governance requirements.

RISK FACTORS

Investing in our securities involves a high degree of risk. You should carefully consider the risk factors set forth under “Risk Factors” described in our most recent Annual Report on Form 20-F, Amendment No. 1 to Form 20-F, and Amendment No. 2 to Form 20-F for the fiscal year ended December 31, 2025, filed with the SEC on May 15, 2026, June 26, 2026, and July 6, 2026, respectively, as supplemented and updated by subsequent current reports on Form 6-K that we will file with the SEC, together with all other information contained or incorporated by reference in this prospectus and any applicable prospectus supplement and in any related free writing prospectus in connection with a specific offering, before making an investment decision. Each of the risk factors could materially and adversely affect our business, operating results, financial condition and prospects, as well as the value of an investment in our securities, and the occurrence of any of these risks might cause you to lose all or part of your investment.

OFFER STATISTICS AND EXPECTED TIMETABLE

We have not determined the amount of net proceeds to be used specifically for the foregoing purposes. As a result, our management will have broad discretion in the allocation of the net proceeds and investors will be relying on the judgment of our management regarding the application of the proceeds of any sale of the securities. If a material part of the net proceeds is to be used to repay indebtedness, we will set forth the interest rate and maturity of such indebtedness in a prospectus supplement. Pending use of the net proceeds will be deposited in interest bearing bank accounts.

CAPITALIZATION AND INDEBTEDNESS

Our capitalization will be set forth in the applicable prospectus supplement or in a report on Form 6-K subsequently furnished to the SEC and specifically incorporated by reference into this prospectus.

DILUTION

If required, we will set forth in a prospectus supplement the following information regarding any material dilution of the equity interests of investors purchasing securities in an offering under this prospectus:

	●	the net tangible book value per share of our equity securities before and after the offering;

	●	the amount of the increase in such net tangible book value per share attributable to the cash payments made by purchasers in the offering; and

	●	the amount of the immediate dilution from the public offering price which will be absorbed by such purchasers.

DESCRIPTION OF SHARE CAPITAL

We are an exempted company with limited liability incorporated under the laws of the Cayman Islands and our affairs are governed by our memorandum and articles of association, as amended from time to time and the Companies Act, and the common law of the Cayman Islands.

The share capital of the Company consists of ordinary shares. As of the date of this prospectus, the Company’s authorized share capital is HK$1,000,000,000 divided into 4,000,000,000 shares with par value of HK$0.25 (equivalent to US$0.03) each and the Company’s issued share capital is HK$5,672,500 divided into 22,690,000 shares of par value of HK$0.25 each. As of the date of this prospectus, the issued and outstanding number of ordinary shares was 22,690,000 shares.

Our Memorandum and Articles of Association

The following are summaries of certain material provisions of the amended and restated memorandum and articles of association and of the Companies Act, insofar as they relate to the material terms of our ordinary shares.

Objects of Our Company. Under our amended and restated memorandum and articles of association, the objects of our company are unrestricted, and we are capable of exercising all the functions of a natural person of full capacity irrespective of any question of corporate benefit, as provided by section 27(2) of the Companies Act.

Ordinary Shares. Our ordinary shares are issued in registered form and are issued when registered in our register of members. We may not issue shares to bearer. Our shareholders who are non-residents of the Cayman Islands may freely hold and vote their shares.

Dividends. The holders of our ordinary shares are entitled to such dividends as may be declared by our board of directors. Our amended and restated memorandum and articles of association provide that dividends may be declared and paid out of the funds of our company lawfully available therefor. Under the laws of the Cayman Islands, our company may pay a dividend out of profit and/or share premium account; provided that in no circumstances may a dividend be paid out of our share premium account if this would result in our company being unable to pay its debts as they fall due in the ordinary course of business.

Voting Rights. Voting at any meeting of shareholders is by show of hands unless a poll is demanded. A poll may be demanded by:

●

the chairperson of such meeting;

●

by at least three shareholders present in person or by proxy for the time being entitled to vote at the meeting;

●

by shareholder(s) present in person or by proxy representing not less than one-tenth of the total voting rights of all shareholders having the right to vote at the meeting; and

●

by shareholder(s) present in person or by proxy and holding shares in us conferring a right to vote at the meeting being shares on which an aggregate sum has been paid up equal to not less than one-tenth of the total sum paid up on all shares conferring that right.

An ordinary resolution to be passed at a meeting by the shareholders requires the affirmative vote of a simple majority of the votes attaching to the ordinary shares cast at a meeting, while a special resolution requires the affirmative vote of no less than two-thirds of the votes cast attaching to the issued and outstanding ordinary shares at a meeting. A special resolution will be required for important matters such as a change of name, making changes to our amended and restated memorandum and articles of association, a reduction of our share capital and the winding up of our company. Our shareholders may, among other things, divide or combine their shares by ordinary resolution.

General Meetings of Shareholders. As a Cayman Islands exempted company, we are not obliged by the Companies Act to call shareholders’ annual general meetings. Our amended and restated memorandum and articles of association provide that we shall, if required by the Companies Act, in each year hold a general meeting as our annual general meeting, and shall specify the meeting as such in the notices calling it, and the annual general meeting shall be held at such time and place as may be determined by our directors. General meetings, including annual general meetings, may be held at such times and in any location in the world as may be determined by the Board. A general meeting or any class meeting may also be held by means of such telephone, electronic or other communication facilities as to permit all persons participating in the meeting to communicate with each other, and participation in such a meeting constitutes presence at such meeting. Unless otherwise determined by our directors, the manner of convening and the proceedings at a general meeting set out in our amended and restated articles of association shall apply, mutatis mutandis, to a general meeting held wholly by or in-combination with electronic means.

Shareholders’ general meetings may be convened by the chairperson of our board of directors or by a majority of our board of directors. Advance notice of at least ten clear days is required for the convening of our annual general shareholders’ meeting (if any) and any other general meeting of our shareholders. A quorum required for any general meeting of shareholders consists of, at the time when the meeting proceeds to business, two shareholders holding shares which carry in aggregate (or representing by proxy) not less than one-third of all votes attaching to issued and outstanding shares in our company entitled to vote at such general meeting.

The Companies Act does not provide shareholders with any right to requisition a general meeting or to put any proposal before a general meeting. However, these rights may be provided in a company’s articles of association. Our amended and restated memorandum and articles of association provide that upon the requisition of any one or more of our shareholders holding shares which carry in aggregate not less than one-third of all votes attaching to the issued and outstanding shares of our company entitled to vote at general meetings, our board will convene an extraordinary general meeting and put the resolutions so requisitioned to a vote at such meeting. However, our amended and restated memorandum and articles of association do not provide our shareholders with any right to put any proposals before annual general meetings or extraordinary general meetings not called by such shareholders.

Transfer of Ordinary Shares. Subject to the restrictions set out below, any of our shareholders may transfer all or any of his or her ordinary shares by an instrument of transfer in the usual or common form or in a form prescribed by NYSE American or any other form approved by our board of directors. Notwithstanding the foregoing, ordinary shares may also be transferred in accordance with the applicable rules and regulations of NYSE American.

Our board of directors may, in its absolute discretion, decline to register any transfer of any ordinary share which is not fully paid up or on which we have a lien. Our board of directors may also decline to register any transfer of any ordinary share unless:

●

the instrument of transfer is lodged with us, accompanied by the certificate for the ordinary shares to which it relates and such other evidence as our board of directors may reasonably require to show the right of the transferor to make the transfer;

●

the instrument of transfer is in respect of only one class of ordinary shares;

●

the instrument of transfer is properly stamped, if required;

●

in the case of a transfer to joint holders, the number of joint holders to whom the ordinary share is to be transferred does not exceed four; and

●

a fee of such maximum sum as the NYSE American may determine to be payable or such lesser sum as our directors may from time to time require is paid to us in respect thereof.

If our directors refuse to register a transfer they shall, within two months after the date on which the instrument of transfer was lodged, send to each of the transferor and the transferee notice of such refusal.

The registration of transfers may, after compliance with any notice required in accordance with the rules of the NYSE American, be suspended and the register closed at such times and for such periods as our board of directors may from time to time determine; provided, however, that the registration of transfers shall not be suspended nor the register closed for more than 30 days in any year as our board may determine. The period of 30 days may be extended for a further period or periods not exceeding 30 days in respect of any year if approved by the shareholders by ordinary resolution.

Liquidation. On the winding up of our company, if the assets available for distribution amongst our shareholders shall be more than sufficient to repay the whole of the share capital at the commencement of the winding up, the surplus shall be distributed amongst our shareholders in proportion to the par value of the shares held by them at the commencement of the winding up, subject to a deduction from those shares in respect of which there are monies due, of all monies payable to our company for unpaid calls or otherwise. If our assets available for distribution are insufficient to repay all of the paid-up capital, such assets will be distributed so that, as nearly as may be, the losses are borne by our shareholders in proportion to the par value of the shares held by them.

Calls on Shares and Forfeiture of Shares. Our board of directors may from time to time make calls upon shareholders for any amounts unpaid on their shares in a notice served to such shareholders at least 14 clear days prior to the specified time and place of payment. The shares that have been called upon and remain unpaid are subject to forfeiture.

Redemption, Repurchase and Surrender of Shares. We may issue shares on terms that such shares are subject to redemption, at our option or at the option of the holders of these shares, on such terms and in such manner as may be determined by our board of directors. Our company may also repurchase any of our shares on such terms and in such manner as have been approved by our board of directors. Under the Companies Act, the redemption or repurchase of any share may be paid out of our company’s profits, share premium or out of the proceeds of a new issue of shares made for the purpose of such redemption or repurchase, or out of capital if our company can, immediately following such payment, pay its debts as they fall due in the ordinary course of business. In addition, under the Companies Act no such share may be redeemed or repurchased (a) unless it is fully paid up, (b) if such redemption or repurchase would result in there being no shares outstanding or (c) if the company has commenced liquidation. In addition, our company may accept the surrender of any fully paid share for no consideration. See “Where You Can Find Additional Information.”

Variations of Rights of Shares. Whenever the capital of our company is divided into different classes the rights attached to any such class may, subject to any rights or restrictions for the time being attached to any class, only be varied with the sanction of a resolution passed by a majority of two-thirds of the votes cast at a separate meeting of the holders of the shares of that class. The rights conferred upon the holders of the shares of any class issued with preferred or other rights shall not, unless otherwise expressly provided by the terms of issue of the shares of that class, be deemed to be varied by the creation, allotment or issue of further shares ranking pari passu with such existing class of shares.

Issuance of Additional Shares. Our amended and restated memorandum and articles of association authorizes our board of directors to issue additional ordinary shares from time to time as our board of directors shall determine, to the extent of available authorized but unissued shares.

Our amended and restated memorandum and articles of association also authorizes our board of directors to establish from time to time one or more series of preference shares and to determine, with respect to any series of preference shares, the terms and rights of that series, including, among other things:

●

the designation of the series;

●

the number of shares of the series;

●

the dividend rights, dividend rates, conversion rights and voting rights; and

●

the rights and terms of redemption and liquidation preferences.

Our board of directors may issue preference shares without action by our shareholders to the extent of available authorized but unissued shares. Issuance of these shares may dilute the voting power of holders of ordinary shares.

Inspection of Books and Records. Holders of our ordinary shares will have no general right under Cayman Islands law to inspect or obtain copies of our list of shareholders or our corporate records. However, our amended and restated memorandum and articles of association have provisions that provide our shareholders the right to inspect our register of shareholders without charge, and to receive our annual audited financial statements. See “Where You Can Find Additional Information.”

Anti-Takeover Provisions. Some provisions of our amended and restated memorandum and articles of association may discourage, delay or prevent a change of control of our company or management that shareholders may consider favorable, including provisions that authorize our board of directors to issue preference shares in one or more series and to designate the price, rights, preferences, privileges and restrictions of such preference shares without any further vote or action by our shareholders.

However, under Cayman Islands law, our directors may only exercise the rights and powers granted to them under our amended and restated memorandum and articles of association for a proper purpose and for what they believe in good faith to be in the best interests of our company.

Exempted Company. We are an exempted company with limited liability under the Companies Act. The Companies Act distinguishes between ordinary resident companies and exempted companies. Any company that is registered in the Cayman Islands but conducts business mainly outside of the Cayman Islands may apply to be registered as an exempted company. The requirements for an exempted company are essentially the same as for an ordinary company except that an exempted company:

●

does not have to file an annual return of its shareholders with the Registrar of Companies;

●

is not required to open its register of members for inspection;

●

does not have to hold an annual general meeting;

●

may issue shares with no par value;

●

may obtain an undertaking against the imposition of any future taxation (such undertakings are usually given for 20 years in the first instance);

●

may register by way of continuation in another jurisdiction and be deregistered in the Cayman Islands;

●

may register as an exempted limited duration company; and

●

may register as a segregated portfolio company.

“Limited liability” means that the liability of each shareholder is limited to the amount unpaid by the shareholder on that shareholder’s shares of the company (except in exceptional circumstances, such as involving fraud, the establishment of an agency relationship or an illegal or improper purpose or other circumstances in which a court may be prepared to pierce or lift the corporate veil).

Transfer Agent and Registrar

The transfer agent and branch registrar for our Ordinary Shares, which will maintain our branch register located in the United States, will be VStock Transfer, LLC. Its address is 18 Lafayette Place, Woodmere, NY 11598.

Listing

Our Ordinary Shares are listed on the NYSE American under the symbol “LUD”

DESCRIPTION OF OUR WARRANTS

We may issue warrants to purchase our debt or equity securities or securities of third parties or other rights, including rights to receive payment in cash or securities based on the value, rate or price of one or more specified commodities, currencies, securities or indices, or any combination of the foregoing. Warrants may be issued independently or together with any other securities and may be attached to, or separate from, such securities. Each series of warrants will be issued under a separate warrant agreement to be entered into between us and a warrant agent. The terms of any warrants to be issued and a description of the material provisions of the applicable warrant agreement will be set forth in the applicable prospectus supplement.

We urge you to read the applicable prospectus supplements and any related free writing prospectuses related to the warrants that we may offer under this prospectus, as well as the complete warrant agreements and warrant certificates that contain the terms of the warrants.

DESCRIPTION OF OUR UNITS

We may issue units consisting of any combination of the other types of securities offered under this prospectus in one or more series. We may evidence each series of units by unit certificates that we will issue under a separate agreement. We may enter into unit agreements with a unit agent. Each unit agent will be a bank or trust company that we select. We will indicate the name and address of the unit agent in the applicable prospectus supplement relating to a particular series of units.

We urge you to read the applicable prospectus supplement and any related free writing prospectus, as well as the complete unit certificate that contains the terms of the units.

DESCRIPTION OF RIGHTS

We may issue rights to purchase Ordinary Shares that we may offer to our securityholders. The rights may or may not be transferable by the persons purchasing or receiving the rights. In connection with any rights offering, we may enter into a standby underwriting or other arrangement with one or more underwriters or other persons pursuant to which such underwriters or other persons would purchase any offered securities remaining unsubscribed for after such rights offering. Each series of rights will be issued under a separate rights agent agreement to be entered into between us and a bank or trust company, as rights agent, that we will name in the applicable prospectus supplement. The rights agent will act solely as our agent in connection with the rights and will not assume any obligation or relationship of agency or trust for or with any holders of rights certificates or beneficial owners of rights.

The prospectus supplement relating to any rights that we offer will include specific terms relating to the offering, including, among other matters:

●

the date of determining the securityholders entitled to the rights distribution;

●

the aggregate number of rights issued and the aggregate number of Ordinary Shares purchasable upon exercise of the rights;

●

the exercise price;

●

the conditions to completion of the rights offering;

●

the date on which the right to exercise the rights will commence and the date on which the rights will expire; and

●

applicable tax considerations.

Each right would entitle the holder of the rights to purchase for cash the principal amount of Ordinary Shares at the exercise price set forth in the applicable prospectus supplement. Rights may be exercised at any time up to the close of business on the expiration date for the rights provided in the applicable prospectus supplement. After the close of business on the expiration date, all unexercised rights will become void.

If less than all of the rights issued in any rights offering are exercised, we may offer any unsubscribed securities directly to persons other than our security holders, to or through agents, underwriters or dealers or through a combination of such methods, including pursuant to standby arrangements, as described in the applicable prospectus supplement.

PLAN OF DISTRIBUTION

We may sell the securities offered through this prospectus (i) to or through underwriters or dealers, (ii) directly to purchasers, including our affiliates, (iii) through agents, or (iv) through a combination of any these methods. The securities may be distributed at a fixed price or prices, which may be changed, market prices prevailing at the time of sale, prices related to the prevailing market prices, or negotiated prices. The prospectus supplement will include the following information:

	●	the terms of the offering;

	●	the names of any underwriters or agents;

	●	the name or names of any managing underwriter or underwriters;

	●	the purchase price of the securities;

	●	any over-allotment options under which underwriters may purchase additional securities from us;

	●	the net proceeds from the sale of the securities;

	●	any delayed delivery arrangements;

	●	any underwriting discounts, commissions and other items constituting underwriters’ compensation;

	●	any initial public offering price;

	●	any discounts or concessions allowed or reallowed or paid to dealers;

	●	any commissions paid to agents; and

	●	any securities exchange or market on which the securities may be listed.

Sale Through Underwriters or Dealers

Only underwriters named in the prospectus supplement are underwriters of the securities offered by the prospectus supplement. If underwriters are used in the sale, the underwriters will acquire the securities for their own account, including through underwriting, purchase, security lending or repurchase agreements with us. The underwriters may resell the securities from time to time in one or more transactions, including negotiated transactions. Underwriters may sell the securities in order to facilitate transactions in any of our other securities (described in this prospectus or otherwise), including other public or private transactions and short sales. Underwriters may offer securities to the public either through underwriting syndicates represented by one or more managing underwriters or directly by one or more firms acting as underwriters. Unless otherwise indicated in the prospectus supplement, the obligations of the underwriters to purchase the securities will be subject to certain conditions, and the underwriters will be obligated to purchase all the offered securities if they purchase any of them. The underwriters may change from time to time any public offering price and any discounts or concessions allowed or reallowed or paid to dealers.

If dealers are used in the sale of securities offered through this prospectus, we will sell the securities to them as principals. They may then resell those securities to the public at varying prices determined by the dealers at the time of resale. The prospectus supplement will include the names of the dealers and the terms of the transaction.

We will provide in the applicable prospectus supplement any compensation we will pay to underwriters, dealers or agents in connection with the offering of the securities, and any discounts, concessions or commissions allowed by underwriters to participating dealers.

Direct Sales and Sales Through Agents

We may sell the securities offered through this prospectus directly. In this case, no underwriters or agents would be involved. Such securities may also be sold through agents designated from time to time. The prospectus supplement will name any agent involved in the offer or sale of the offered securities and will describe any commissions payable to the agent. Unless otherwise indicated in the prospectus supplement, any agent will agree to use its reasonable best efforts to solicit purchases for the period of its appointment.

We may sell the securities directly to institutional investors or others who may be deemed to be underwriters within the meaning of the Securities Act with respect to any sale of those securities. The terms of any such sales will be described in the prospectus supplement.

Delayed Delivery Contracts

If the prospectus supplement indicates, we may authorize agents, underwriters or dealers to solicit offers from certain types of institutions to purchase securities at the public offering price under delayed delivery contracts. These contracts would provide for payment and delivery on a specified date in the future. The contracts would be subject only to those conditions described in the prospectus supplement. The applicable prospectus supplement will describe the commission payable for solicitation of those contracts.

Market Making, Stabilization and Other Transactions

Unless the applicable prospectus supplement states otherwise, other than our Ordinary Shares, all securities we offer under this prospectus will be a new issue and will have no established trading market. We may elect to list offered securities on an exchange or in the over-the-counter market. Any underwriters that we use in the sale of offered securities may make a market in such securities, but may discontinue such market making at any time without notice. Therefore, we cannot assure you that the securities will have a liquid trading market.

Any underwriter may also engage in stabilizing transactions, syndicate covering transactions and penalty bids in accordance with Rule 104 under the Securities Exchange Act. Stabilizing transactions involve bids to purchase the underlying security in the open market for the purpose of pegging, fixing or maintaining the price of the securities. Syndicate covering transactions involve purchases of the securities in the open market after the distribution has been completed in order to cover syndicate short positions.

Penalty bids permit the underwriters to reclaim a selling concession from a syndicate member when the securities originally sold by the syndicate member are purchased in a syndicate covering transaction to cover syndicate short positions. Stabilizing transactions, syndicate covering transactions and penalty bids may cause the price of the securities to be higher than it would be in the absence of the transactions. The underwriters may, if they commence these transactions, discontinue them at any time.

General Information

Agents, underwriters, and dealers may be entitled, under agreements entered into with us, to indemnification by us against certain liabilities, including liabilities under the Securities Act. Our agents, underwriters, and dealers, or their affiliates, may be customers of, engage in transactions with or perform services for us, in the ordinary course of business.

TAXATION

Please refer to “Item 10. Additional Information - 10.E. Taxation” of our 2025 Annual Report, which is herein incorporated by reference. Certain income tax considerations relating to the purchase, ownership and disposition of any of the securities offered by this prospectus will be set forth in the applicable prospectus supplement relating to the offering of those securities.

MATERIAL CONTRACTS

Our material contracts are described in the documents incorporated by reference into this prospectus. See “Incorporation of Documents by Reference” below.

MATERIAL CHANGES

Except as otherwise described in our most recent annual report on Form 20-F, Amendment No. 1 to Form 20-F and Amendment No. 2 to Form 20-F, in our Reports on Form 6-K furnished under the Exchange Act and incorporated by reference herein and as disclosed in this prospectus, no reportable material changes have occurred since December 31, 2025.

LEGAL MATTERS

We are being represented by Loeb & Loeb LLP with respect to certain legal matters of U.S. federal securities. The validity of the Ordinary Shares offered in this offering and certain legal matters as to Cayman Islands law will be passed upon for us by Conyers Dill & Pearman.

EXPERTS

The consolidated financial statements of December 31, 2025, included in this prospectus have been so included in reliance on the report of AOGB CPA Limited, Independent Registered Public Accounting Firm, an independent registered public accounting firm, given on the authority of said firm as experts in auditing and accounting. The office of AOGB CPA Limited is located at Suite 2501-03, Tesbury Centre, 28 Queen’s Road East, Admiralty, Hong Kong.

The consolidated financial statements of December 31, 2024, included in this prospectus have been so included in reliance on the report of ZH CPA, LLC, Independent Registered Public Accounting Firm, an independent registered public accounting firm, given on the authority of said firm as experts in auditing and accounting. The office of ZH CPA, LLC is located at 999 18^th Street, Suite 3000, Denver, Colorado, 80202 USA.

INTERESTS OF EXPERTS AND COUNSEL

No named expert of or counselor to us was employed on a contingent basis, or owns an amount of our shares (or those of our subsidiaries) which is material to that person, or has a material, direct or indirect economic interest in us or that depends on the success of the offering.

SERVICE OF PROCESS AND ENFORCEMENT OF CIVIL LIABILITIES

We are incorporated under the laws of the Cayman Islands. Service of process upon us and upon our directors and officers and the Cayman Islands experts named in this prospectus, many of whom reside outside of the United States, may be difficult to obtain within the United States. Furthermore, because substantially all of our assets and substantially all of our directors and officers are located outside the United States, any judgment obtained in the United States against us or any of our directors and officers may be difficult to collect within the United States.

We have irrevocably appointed Cogency Global Inc. as our agent to receive service of process in any action against us in any U.S. federal or state court arising out of this offering or any purchase or sale of securities in connection with this offering. The address of our agent is 122 East 42^nd Street, 18^th Floor, New York, NY 10168.

Conyers Dill & Pearman, our counsel as to Cayman Islands law, has advised us that there is uncertainty as to whether the courts of the Cayman Islands would (1) recognize or enforce judgments of U.S. courts obtained against us or our directors or officers that are predicated upon the civil liability provisions of the federal securities laws of the United States or the securities laws of any state in the United States, or (2) entertain original actions brought in the Cayman Islands against us or our directors or officers that are predicated upon the federal securities laws of the United States or the securities laws of any state in the United States.

Conyers Dill & Pearman has informed us that although there is no statutory enforcement in the Cayman Islands of judgments obtained in the federal or state courts of the United States, the courts of the Cayman Islands would recognize as a valid judgment, a final and conclusive judgment in personam obtained in the federal or state courts of the United States against us under which a sum of money is payable (other than a sum of money payable in respect of multiple damages, taxes or other charges of a like nature or in respect of a fine or other penalty) or, in certain circumstances, an in personam judgment for non-monetary relief, and would give a judgment based thereon provided that (a) such courts had proper jurisdiction over the parties subject to such judgment; (b) such courts did not contravene the rules of natural justice of the Cayman Islands; (c) such judgment was not obtained by fraud; (d) the enforcement of the judgment would not be contrary to the public policy of the Cayman Islands; (e) no new admissible evidence relevant to the action is submitted prior to the rendering of the judgment by the courts of the Cayman Islands; and (f) there is due compliance with the correct procedures under the laws of the Cayman Islands. However, the Cayman Islands courts are unlikely to enforce a judgment obtained from United States courts under civil liability provisions of the U.S. federal securities law if such judgment is determined by the courts of the Cayman Islands to give rise to obligations to make payments that are penal or punitive in nature. Because such a determination has not yet been made by a court of the Cayman Islands, it is uncertain whether such civil liability judgments from U.S. courts would be enforceable in the Cayman Islands. A Cayman Islands court may stay enforcement proceedings if concurrent proceedings are being brought elsewhere.

Substantially all of our assets are located outside the United States. In addition, a majority of our directors and officers are nationals or residents of jurisdictions other than the United States and all or a substantial portion of their assets are located outside the United States. As a result, it may be difficult for investors to effect service of process within the United States upon us or these persons.

Part II — Information Not Required in the Prospectus

Item 8. 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 the 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.

Our amended and restated memorandum and articles of association provide that we shall indemnify our 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, wilful default or fraud, in or about the conduct of our company’s business or affairs (including as a result of any mistake of judgment) or in the execution or discharge of his duties, powers, authorities or discretions, including without prejudice to the generality of the foregoing, any costs, expenses, losses or liabilities incurred by such director or officer in defending (whether successfully or otherwise) any civil proceedings concerning our company or its affairs in any court whether in the Cayman Islands or elsewhere. This standard of conduct is generally the same as permitted under the Delaware General Corporation Law for a Delaware corporation.

In addition, we have entered into indemnification agreements with our directors and executive officers that provide such persons with additional indemnification rights beyond those provided in our amended and restated memorandum and articles of association.

Insofar as indemnification for liabilities arising under the Securities Act of 1933, as amended, may be permitted to our directors, officers or persons controlling us pursuant to the foregoing provisions, we have been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act and is therefore unenforceable.

Item 10. 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 the 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 the 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 end of the estimated maximum offering range may be reflected in the form of prospectus filed with the SEC pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than 20% 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 material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement; provided, however, that paragraphs (a)(1)(i), (a)(1)(ii) and (a)(1)(iii) of this item 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 SEC by the registrant pursuant to Section 13 or Section 15(d) of the Exchange Act that are incorporated by reference in the registration statement, or is contained in a form of prospectus filed pursuant to Rule 424(b) that is part of the 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.

	(4)	To file a post-effective amendment to the registration statement to include any financial statements required by Item 8.A. of Form 20-F at the start of any delayed offering or throughout a continuous offering. Financial statements and information otherwise required by Section 10(a)(3) of the Securities Act need not be furnished, provided that the registrant includes in the prospectus, by means of a post-effective amendment, financial statements required pursuant to this paragraph (a)(4) and other information necessary to ensure that all other information in the prospectus is at least as current as the date of those financial statements. Notwithstanding the foregoing, a post-effective amendment need not be filed to include financial statements and information required by Section 10(a)(3) of the Securities Act or Item 8.A of Form 20-F if such financial statements and information are contained in periodic reports filed with or furnished to the SEC by the registrant pursuant to Section 13 or Section 15(d) of the Exchange Act that are incorporated by reference in this registration statement.

	(5)	That, for the purpose of determining liability under the Securities Act to any purchaser:

(i)

Each prospectus filed by the registrant pursuant to Rule 424(b)(3) shall be deemed to be part of the registration statement as of the date the filed prospectus was deemed part of and included in the registration statement; and

II-2

(ii)

Each prospectus required to be filed pursuant to Rule 424(b)(2), (b)(5) or (b)(7) as part of a registration statement in reliance on Rule 430B relating to an offering made pursuant to Rule 415(a)(1)(i), (vii) or (x) for the purpose of providing the information required by Section 10(a) of the Securities Act shall be deemed to be part of and included in the registration statement as of the earlier of the date such form of prospectus is first used after effectiveness or the date of the first contract of sale of securities in the offering described in the prospectus. As provided in Rule 430B, for liability purposes of the issuer and any person that is at that date an underwriter, such date shall be deemed to be a new effective date of the registration statement relating to the securities in the registration statement to which that prospectus relates, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof; provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such effective date, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such effective date.

(6)

That, for the purpose of determining liability of the registrant under the Securities Act to any purchaser in the initial distribution of the securities:

The undersigned registrant undertakes that in a primary offering of securities of the undersigned registrant pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser:

	(i)	Any preliminary prospectus or prospectus of the undersigned registrant relating to the offering required to be filed pursuant to Rule 424;

	(ii)	Any free writing prospectus relating to the offering prepared by or on behalf of the undersigned registrant or used or referred to by the undersigned registrant;

	(iii)	The portion of any other free writing prospectus relating to the offering containing material information about the undersigned registrant or its securities provided by or on behalf of the undersigned registrant; and

	(iv)	Any other communication that is an offer in the offering made by the undersigned registrant to the purchaser.

	(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 the 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 Securities and Exchange 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.
