**INTRODUCTION**

In this Annual Report, references to "us," "we," and "Company" are to Euro Tech Holdings Company Limited and its subsidiaries, unless otherwise expressly stated or the context otherwise requires.

**Forward Looking Statements**

This Annual Report contains forward looking statements within the meaning of Section 21E of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), and Section 27A of the Securities Act of 1933, as amended (the "Securities Act"). Additional written or oral forward looking statements may be made by the Company from time to time in filings with the Securities and Exchange Commission (the "Commission") or otherwise. These statements are based on management's current expectations, estimates, assumptions, and beliefs about future events, conditions, and financial performance. Such statements may include, but are not limited to, projections of revenues, income or loss, capital expenditures, plans for future operations, financing needs or plans, the competitive environment, and plans relating to products or services of the Company, as well as assumptions relating to the foregoing. The words "believe," "expect," "anticipate," "estimate," "project," "intend," "plan," "may," "will," "would," "could," "should," and similar expressions are intended to identify forward-looking statements, which speak only as of the date the statement was made. Readers are cautioned not to place undue reliance on these forward-looking statements. Forward-looking statements are inherently subject to risks and uncertainties, some of which cannot be predicted or quantified. Future events and actual results could differ materially from those set forth in, contemplated by, or underlying the forward-looking statements. Important factors that could cause actual results to differ materially include, but are not limited to, those discussed under "Item 3.D — Risk Factors" in this Annual Report. Except as required by applicable law or regulation, the Company undertakes no obligation to publicly update or revise any forward-looking statement, whether as a result of new information, future events, or otherwise.

These forward-looking statements include, but are not limited to, statements about:

· our goals, business plans and growth strategies;

· our expectations regarding demand for, and market acceptance of, the products and services we distribute and provide;

· competition in the industries and markets in which we operate;

· our future business development, results of operations and financial condition;

· expected changes in our revenues and certain cost and expense items, and our margins;

· government policies and regulations relating to our corporate structure, business and industry;

· the regulatory environment in which we operate in mainland China, Hong Kong, and globally;

· our ability to comply with the continued listing standards of the Nasdaq Capital Market;

· general economic and business conditions in mainland China, Hong Kong, and elsewhere;

· assumptions underlying or related to any of the foregoing.

We caution you not to place undue reliance on any forward-looking statements contained in this Annual Report. These statements should be read in conjunction with the risk factors and other cautionary statements included in this Annual Report, including those set forth in Part I, Item 3.D "Risk Factors," Item 5 "Operating and Financial Review and Prospects," and the notes to our Consolidated Financial Statements, which describe factors that could cause our actual results to differ materially from those contained in any forward-looking statements. The risks described in this Annual Report are not exhaustive. We operate in a continuously evolving environment in which new risks and uncertainties emerge from time to time. It is not possible for our management to predict all such risk factors and uncertainties, nor can we assess the impact of all factors on our business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward-looking statements. We qualify all of our forward-looking statements by these cautionary statements.

You should not rely upon forward-looking statements as predictions of future events. We undertake no obligation to update or revise any forward-looking statements, whether as a result of new information, future events, or otherwise, after the date on which the statements are made or to reflect the occurrence of unanticipated events, except as required by applicable law or regulation.

**U.S. GAAP, Fiscal Year, and Exchange Rate Information**

The Company has prepared its consolidated financial statements in accordance with accounting principles generally accepted in the United States ("U.S. GAAP"). The Company's fiscal year ends on December 31. References in this Annual Report to "Fiscal 2023," "Fiscal 2024," and "Fiscal 2025" are to the fiscal years ended December 31, 2023, 2024, and 2025, respectively.

Unless otherwise indicated, all references in this Annual Report to "U.S. Dollars," "US$," or "$" are to United States dollars, all references to "HK Dollars" or "HK$" are to Hong Kong dollars, and all references to "RMB" or "Renminbi" are to Chinese Renminbi.

The Company maintains its books and records in U.S. Dollars. Its subsidiaries and affiliates maintain their books and records in U.S. Dollars, HK Dollars or Renminbi.

The Company's financial statements are presented in U.S. Dollars. Translations of amounts from HK Dollars into U.S. Dollars are made at the rate of HK$7.8000 to US$1.00, which was the year-end exchange rate as of December 31, 2025 and reflects the pegged rate between the HK dollar and the U.S. dollar.

For the purpose of translating Blue Sky's balance sheet items, which are denominated in Renminbi, into U.S. Dollars, the Company applies a two-step translation methodology consistent with its corporate structure. Renminbi-denominated balance sheet items are first translated into HK Dollars at the year-end RMB/HK$ exchange rate of RMB0.8957 per HK$1.00 as of December 31, 2025, and then translated into U.S. Dollars at the HK$/US$ year-end rate of HK$7.8000 per US$1.00, resulting in an implied effective year-end exchange rate of approximately RMB6.9865 per US$1.00. Income statement items are translated at the average RMB-to-US$ rate of RMB7.1737 per US$1.00 for Fiscal 2025. Exchange differences arising from translation are recorded in other comprehensive income.

We make no representation that any Renminbi, Hong Kong Dollars or U.S. Dollar amounts could have been, or could be, converted into U.S. Dollars, Hong Kong Dollars or Renminbi, as the case may be, at any particular rate, at the rates stated above, or at all.

**PART I**

**ITEM 3. KEY INFORMATION** 

**China Section**

**Our Corporate Structure** 

As an investor, you hold an interest in Euro Tech Holdings Company Limited ("Euro Tech"). Euro Tech is a holding company incorporated in the British Virgin Islands (the "BVI") and does not itself conduct any material operations. Euro Tech conducts its business operations exclusively through its direct and indirect subsidiaries, which are incorporated in Singapore, Hong Kong, mainland China, and the BVI, as further explained below. As an investor, you directly hold an interest in Euro Tech but do not directly hold equity interest in Euro Tech's subsidiaries - which are the entities through which the Company's business operations are conducted. This structure involves certain risks to you, as further described in Part I, Item 3.D "Risk Factors," below.

The Company has one wholly owned subsidiary in Singapore, namely, Euro Tech Global Pte. Limited ("Euro Tech Global"). Euro Tech Global serves solely as an investment holding company and does not conduct any operations directly.

Euro Tech Global has one wholly owned subsidiary in Hong Kong, namely, Euro Tech (Far East) Limited ("Far East"). Far East engages in the marketing and trading of water and wastewater treatment-related process control, analytical and testing instruments, disinfection equipment, supplies, and related automation systems.

Far East has one wholly owned subsidiary in mainland China, namely, Euro Tech Trading (Shanghai) Limited ("ETTS"). ETTS ceased its active business operations in 2021 and is currently inactive.

Far East holds 58% of the total equity of the following entities: (i) PACT Environmental Technology PTE. LTD., a company incorporated in Singapore ("Pact Singapore"), (ii) Yixing Pact Environmental Technology Co., Ltd., a company incorporated in mainland China ("Yixing"), and (iii) Pact Asia Pacific Limited, a company incorporated in the BVI ("Pact"). Pact Singapore focuses on marketing and provision of after-sales services for ballast water treatment systems and customized industrial wastewater solutions, as well as equipment fabrication. Yixing focuses on the design, manufacturing and operation of water and waste water treatment and water desalination machinery and equipment. Pact is currently a dormant entity with no active business operations.

Far East also holds 19.42% of the total equity of Zhejiang Tianlan Environmental Protection Technology Co., Ltd., a company incorporated in mainland China ("Blue Sky"). Blue Sky focuses on the design, manufacturing, installation, testing of waste-gas treatment equipment and operation management of the treatment of waste gases.

The following diagram illustrates the corporate structure of us and our subsidiaries (including Blue Sky in which we hold only 19.42% of the total equity thereof), as of the date of the Annual Report:

We acknowledge that Chinese regulatory authorities could disallow our holding company structure, which could result in a material change in our operations and/or a material change in the value of your securities, including causing the value of such securities to significantly decline or become worthless. Please see "Item 3.D - Risk Factors— Risks Related to the Company Itself – Chinese regulatory authorities could disallow our holding company structure" for a more detailed discussion on this matter.

**Risks Associated with Being Based in and Having the Majority of Our Operations in China**

We conduct a substantial portion of our business through our subsidiaries in mainland China and Hong Kong. We face various legal and operational risks associated with being based in and having the majority of our operations in mainland China and Hong Kong. Changes in PRC economic, political, or social conditions, or government policies could materially and adversely affect our business and results of operations.

The PRC government has significant authority to exert influence over the ability of China-based companies, including us, to conduct business, and investors in Euro Tech face potential uncertainty as a result. The PRC government may intervene in or influence our operations at any time, with little or no advance notice. These risks include, among others: significant oversight and discretion by PRC governmental authorities over our business and financing activities; requirements for regulatory approvals for overseas offerings by, and foreign investment in, China-based issuers; enforcement of anti-monopoly and data security regulations; and the risk of delisting if the Public Company Accounting Oversight Board (the "PCAOB") determines at any time that it is unable to conduct complete inspections of our auditors. The materialization of any of these risks may impact our ability to conduct certain businesses, accept foreign investments, or maintain our listing on a United States stock exchange.

In addition, there are risks and uncertainties regarding the enforcement of laws in China, and laws, rules, and regulations in China can change quickly with little advance notice. The materialization of these risks could result in a material adverse change to our business operations and financial condition, significantly limit or completely hinder our ability to offer or continue to offer securities to investors, and cause our shares to significantly decline in value or become worthless.

See "Item 3.D — Risk Factors — Certain Risks Relating to Doing Business in China" for a more detailed discussion of these matters, including risks relating to changes in Chinese laws and regulations (including those relating to taxation, environmental regulation, and restrictions on foreign investment), changes in PRC government economic and political policies, and uncertainties in the PRC legal system.

An investment in our shares involves a high degree of risk and should be considered speculative. You should carefully consider all of the risk factors set out in "*Item 3.D - Risk Factors*" and all other information contained in this Annual Report before investing in our shares. If any of the events described in those risk factors occurs, our business, prospects, financial condition, results of operations, or cash flows could be materially and adversely affected, the trading price of our shares could decline, and all or part of your investment may be lost.

**The Holding Foreign Companies Accountable Act**

Pursuant to the Holding Foreign Companies Accountable Act (the "HFCAA"), if the SEC determines that we have filed audit reports issued by a registered public accounting firm that has not been subject to inspections by the PCAOB for two consecutive years, the SEC will prohibit our shares from being traded on a national securities exchange or in the over-the-counter trading market in the United States.

On December 16, 2021, the PCAOB issued a report notifying the SEC of its determination that the PCAOB was unable to inspect or investigate completely registered public accounting firms headquartered in mainland China or Hong Kong. Union Power HK CPA Limited ("Union Power"), the firm that audited our financial statements for the fiscal years ended December 31, 2021 and December 31, 2020, was included in that report. As a result, on June 14, 2022, we were added to the SEC's conclusive list of "Commission-Identified Issuers" identified under the HFCAA.

| *[**Table of Contents**](#TOC)* |

On December 15, 2022, the PCAOB vacated its previous determinations that it was unable to inspect and investigate completely PCAOB-registered public accounting firms headquartered in mainland China and Hong Kong. Accordingly, as of the date of that vacatur, no issuers were at risk of having their securities subject to a trading prohibition under the HFCAA solely on the basis of those prior determinations.

In January 2023, we appointed J&S Associate PLT ("J&S") as our independent registered public accounting firm. J&S is headquartered in Malaysia and is subject to inspections by the PCAOB. We believe that the appointment of J&S has substantially reduced the risk of our being identified as a "Commission-Identified Issuer" under the HFCAA and the risk of our securities being prohibited from trading on a national securities exchange or in the over-the-counter trading market in the United States.

Each year, the PCAOB will determine whether it can inspect and investigate completely audit firms in mainland China, Hong Kong, and other jurisdictions. As of the date of this Annual Report, the PCAOB has not issued any determination that it is unable to inspect or investigate completely registered public accounting firms headquartered in any jurisdiction. However, there can be no assurance that the PCAOB will not issue such a determination in the future. If the PCAOB were to determine that it no longer has full access to inspect and investigate completely accounting firms in certain jurisdictions, and we use an accounting firm headquartered in one of those jurisdictions to issue an audit report on our financial statements filed with the SEC, we could be identified as a Commission-Identified Issuer following the filing of the Annual Report on Form 20-F for the relevant fiscal year. There can be no assurance that we would not be identified as a Commission-Identified Issuer for any future fiscal year, and if we were so identified for two consecutive years, we would become subject to the prohibition on trading under the HFCAA.

*See* "Item 3.D – Risk Factors— Risks Related to the Company Itself - The enactment of the Holding Foreign Companies Accountable Act and the adoption of any rules, legislations or other efforts to increase U.S. regulatory access to audit information could cause uncertainty and our securities listed on the Nasdaq could be delisted or prohibited from being traded over-the-counter if we are unable to meet the PCAOB requirement in time" for a more detailed discussion on this matter.

**Permissions or Approvals Required to be Obtained from Chinese Authorities** 

Our business focuses on the design, sale and distribution of water and wastewater treatment tools and equipment. The group companies that are active in business operations are Far East in Hong Kong, Pact Singapore in Singapore, and Yixing in mainland China. Euro Tech Global is the Company's wholly-owned subsidiary and an investment holding company. Far East is the wholly-owned subsidiary of Euro Tech Global. Far East holds 58% of the equity of Pact Singapore, Yixing and Pact respectively.

Based on our internal assessment, neither the Company nor any of its subsidiaries is required to obtain any permissions or approvals from Chinese authorities to operate their respective businesses or to offer the Company's securities, as currently conducted, except that group companies located in mainland China are required to obtain a business license to operate. As set out in the table below, such group companies have obtained their respective business licenses. Neither the Company nor any of its subsidiaries has ever been requested by any Chinese authority to obtain any other permissions or approvals to conduct their respective businesses or to offer the Company's securities. In addition, please note that Euro Tech Trading (Shanghai) Limited (listed below) has ceased its active business operations already.

We did not rely upon an opinion of counsel with respect to our conclusions regarding whether we are required to obtain permissions and approvals to operate our business or to offer securities to investors. The basis of our assessment is as follows:

· Business history: The Company has been primarily a distributor of advanced water treatment equipment, laboratory instruments, analyzers, test kits, related supplies, and power generation equipment (including recorders and power quality analyzers) for more than 20 years. During this time, we have never been required to apply for any permissions or approvals from Chinese authorities to conduct our business;

· Cybersecurity and data regulations: We are aware of regulatory developments relating to Chinese authorities' focus on cross-border data transfer, as further described in "*Item 4.B — Business Overview – Regulations*." We do not believe that our listing of ordinary shares requires permissions or approvals from Chinese authorities. As a distributor of advanced water treatment equipment, laboratory instruments, analyzers, test kits, related supplies, and power generation equipment to corporate customers (and not to individual end-users), we do not consider ourselves to be a critical information infrastructure operator or online platform operator subject to more stringent requirements under China's Cybersecurity Review Measures (effective February 15, 2022). Our customers in mainland China are corporate customers rather than individual customers, and accordingly we do not currently hold, and do not anticipate collecting, personal information of more than one million users, which we understand would otherwise subject us to review under the Cybersecurity Review Measures.

Notwithstanding the foregoing, it is possible that changes in applicable laws and regulations may render us subject to additional rules and requirements. It is also possible that government agencies may impose more stringent requirements in practice, or that our interpretation of applicable rules and regulations may prove to be inaccurate. The PRC government has indicated an intent to exert greater oversight and control over overseas offerings by, and foreign investment in, China-based issuers, and we cannot assure you that we will not be subject to additional requirements in the future.

See "Item 3.D – Risk Factor – Certain Risks Relating to Doing Business in China" for a more detailed discussion of these matters, including risks relating to changes in Chinese laws and regulations and cybersecurity and data protection compliance.

**Transfer of Cash through Our Organization**

Euro Tech may transfer cash to its subsidiaries through capital contributions and/or intercompany loans, and Euro Tech's subsidiaries may transfer cash to Euro Tech through dividends or other distributions and/or intercompany loans. Currently, Euro Tech's subsidiaries do not require loans or capital contributions from Euro Tech to fund their operations, and Euro Tech's subsidiaries do not currently intend to pay any cash dividends in the near future.

Dividends

During the three fiscal years ended December 31, 2023, 2024, and 2025, Euro Tech paid cash dividends to its shareholders (including U.S. investors) of nil, US$617,303.92, and nil, respectively. The source of such cash dividends was cash dividends and distributions received from Far East. For a discussion of mainland China and United States federal income tax considerations in connection with an investment in our ordinary shares, see "Item 10.E - Taxation."

During the two fiscal years ended December 31, 2023 and 2024, Far East paid cash dividends to Euro Tech of nil and US$974,359, respectively. During the fiscal year ended December 31, 2025, Far East paid no cash dividends to Euro Tech Global.

Euro Tech Global was incorporated in 2025. During the fiscal year ended December 31, 2025, Euro Tech Global paid no cash dividends to Euro Tech.

Cash Transfers for Working Capital Purposes

During the three fiscal years ended December 31, 2023, 2024 and 2025, Far East made cash transfers for working capital purposes to its wholly-owned subsidiaries in Shanghai, namely Shanghai Euro Tech Limited and Euro Tech Trading (Shanghai) Limited in the amounts of US$129,200, US$26,455, and US$52,411, respectively. Shanghai Euro Tech Limited was deregistered on October 8, 2024.

To date, Far East has made an aggregate capital contribution of US$350,000 to Shanghai Euro Tech Limited, its wholly-owned subsidiary, in satisfaction of its obligation to pay in the registered capital of that entity. Shanghai Euro Tech Limited was deregistered on October 8, 2024.

During the three fiscal years ended December 31, 2023, 2024, and 2025, other than the cash transfers described above, there were no transfers of other assets among Euro Tech and its subsidiaries.

**Restrictions and Limitations on Transfer of Cash and Cash Dividend Distribution**

Our cash dividends, if any, will be paid in U.S. Dollars. The PRC government imposes controls on the convertibility of Renminbi into foreign currencies and, in certain cases, on the remittance of currency out of China. A substantial portion of our income is received in Renminbi, and shortages in available foreign currencies may restrict our ability to pay dividends or satisfy other foreign currency-denominated obligations, if any.

Under existing PRC foreign exchange regulations, payments of current account items - including profit distributions, interest payments, and expenditures from trade-related transactions - may be made in foreign currencies without prior approval from the State Administration of Foreign Exchange of China ("SAFE"), provided that certain procedural requirements are met. Approval from appropriate government authorities is required if Renminbi is converted into foreign currency and remitted out of China to pay capital account expenses, such as the repayment of loans denominated in foreign currencies. The PRC government may, at its discretion, impose restrictions on access to foreign currencies for current account transactions in the future, in which case we may not be able to pay dividends in foreign currencies to our shareholders.

If we are considered a PRC tax resident enterprise for tax purposes, any dividends we pay to our overseas shareholders may be regarded as China-sourced income and as a result may be subject to PRC withholding tax.

Relevant PRC laws and regulations permit the PRC companies to pay dividends only out of their accumulated retained earnings, if any, as determined in accordance with PRC accounting standards and regulations. Our PRC subsidiaries may only distribute dividends upon approval of their respective shareholders, and only after meeting the PRC requirements for appropriation to statutory reserves. Under PRC laws and regulations, each of our subsidiaries incorporated in mainland China is required to set aside at least 10% of its after-tax profits each year - after making up for any prior years' accumulated losses - to fund certain statutory reserves, until the aggregate amount of such fund reaches 50% of its registered capital.

As a result of these and other restrictions under the PRC laws and regulations, our PRC subsidiaries are restricted from transferring a portion of their net assets to the Company in the form of dividends, loans, or advances. Although the Company does not currently require dividends, loans, or advances from its PRC subsidiaries for working capital or other funding purposes, the Company may in the future require additional cash resources from its PRC subsidiaries due to changes in business conditions, to fund future acquisitions or developments, or to declare and pay dividends or distributions to the Company's shareholders.

To the extent that cash in the business is held by a PRC entity, such funds may not be available to fund operations or for other use outside of the PRC as a result of interventions in, or the imposition of restrictions and limitations on, the ability of the Company or its subsidiaries to transfer cash, whether imposed by the PRC government or otherwise. Please see "Item 3.D – Risk Factors — The PRC government imposes controls on currency conversion and the remittance of funds out of China, which may restrict the Company's ability to transfer cash and pay dividends." for details on this matter.

**Cash Management Policies For Cash Transfer** 

Euro Tech and its subsidiaries have adopted substantially similar cash management policies, as described below. With respect to any transfer of funds, dividends, or other distributions to affiliated companies, the finance department of the relevant group company (the "Finance Department") must obtain the requisite approval of the board of directors and/or shareholders prior to applying to the competent governmental authorities and banks to effectuate the intended transactions. If any such transaction involves a payment to an overseas entity, the Finance Department must also submit a payment application to Euro Tech's Chairman and Chief Financial Officer and receive their approval in writing. Following receipt of such approval, the Finance Department may request the Chairman's authorized representative - who must not be an employee of the relevant group company - to affix the company's stamp to the payment application. With such stamped application, the Finance Department may then effectuate the fund transfer through the relevant bank. The Finance Department is also responsible for taking all actions necessary to comply with the applicable rules and requirements of the foreign exchange authority and tax bureau in China, to the extent applicable.

**D. RISK FACTORS** 

An investment in our shares involves a high degree of risk. Below please find a summary of the principal risks we face, organized under relevant headings. You should carefully consider the risks described below, together with all of the other information included in this Annual Report, before making an investment decision. The risks below are not the only ones we face. Additional risks not currently known by us or that we deem immaterial may also impair our business operations. If any of the following and other risks actually occurs, our business, prospects, financial condition or results of operations could suffer. In that case, the trading price of our shares could decline, and you may lose all or part of your investment. This Annual Report also contains forward looking statements that involve risks and uncertainties. Our results could materially differ from those anticipated in these forward looking statements as a result of certain factors, including the risks we face as described below and elsewhere. See "– Forward Looking Statements."

**Certain Risks Relating to Doing Business in China.**

**A substantial portion of our operations are located in China through our subsidiaries. Our ability to operate in China may be impaired by changes in Chinese laws and regulations, including those relating to taxation, environmental regulation, restrictions on foreign investment, and other matters.** 

We conduct a substantial portion of our business in China through our subsidiaries, whose operations are governed by PRC laws, rules, and regulations. The PRC government has exercised and continues to exercise substantial control over virtually every sector of the Chinese economy through regulation and state ownership. Because PRC laws, rules and regulations are relatively new and quickly evolving, and because of the limited number of published decisions and the non-precedential nature of these decisions, and because the laws, rules and regulations often give the relevant regulator certain discretion in how to enforce them, the interpretation and enforcement of these laws, rules and regulations involve uncertainties and can be inconsistent and unpredictable. Therefore, it is possible that our existing operations may be found not to be in full compliance with relevant laws and regulations in the future. In addition, the PRC legal system is based in part on government policies and internal rules, some of which are not published on a timely basis or at all, and which may have a retroactive effect. As a result, we may not be aware of our violation of these policies and rules until after the occurrence of the violation.

The PRC government has significant oversight and discretion over the conduct of our business, and may intervene in or influence our operations through adopting and enforcing rules and regulatory requirements. In recent years, the PRC government has published new policies that significantly affected certain industries such as the education and internet industries, and we cannot rule out the possibility that it will in the future further release regulations or policies regarding our industry that could require us to seek permission from PRC authorities to continue to operate our business. In addition, in recent years the PRC government has enhanced regulation in areas such as anti-monopoly, anti-unfair competition, cybersecurity and data privacy. The PRC government may further promulgate relevant laws, rules and regulations that may impose additional and significant obligations and liabilities on Chinese companies. These laws and regulations can be complex and stringent, and many are subject to change and uncertain interpretation, which could result in claims, change to our business practices, regulatory investigations, penalties, increased cost of operations, or otherwise affect our business. As a result, our business, financial condition and results of operations could be adversely affected and the trading prices of our ordinary shares could decline.

The PRC government has also enhanced its regulatory oversight of Chinese companies listing overseas, including enhanced oversight of overseas equity financing and listing by Chinese companies. It is uncertain when and whether we will be required to obtain permission from the PRC government to list on U.S. exchanges in the future, and even if such permission is obtained, whether it will be later denied or rescinded. No entity in our organization is currently (i) required to obtain permission from any Chinese authorities to list on any U.S. exchange or issue our ordinary shares to foreign investors or (ii) required to obtain permission from China Securities Regulatory Commission ("CSRC"), Cyberspace Administration of China ("CAC"), or any other governmental authority, and no entity in our organization has received any such permissions or any notice of denial of such permissions. However, our operations could be adversely affected, directly or indirectly, by existing or future laws and regulations relating to our business or industry, particularly in the event permission to list on U.S. exchanges becomes required, or if such permission may be withheld or rescinded once granted.

Governmental actions in China, including any decision to intervene or influence our operations at any time or to exert control over an offering of securities conducted overseas and/or foreign investment in China-based issuers, may cause us to make material changes to our operations, may limit or completely hinder our ability to offer or continue to offer securities to investors, and/or may cause the value of such securities to significantly decline or be worthless.

In addition, the PRC government has broad authority to nationalize or expropriate private enterprises or assets. Although we have no reason to believe that any of our operations or assets are currently at risk of nationalization or expropriation, there can be no assurance that the PRC government will not take such action in the future. Any such action could result in the loss of some or all of our investments, assets, or operations in China, and could have a material adverse effect on our business, financial condition, and results of operations.

**Changes in the economic and political policies of the PRC government could have a material and adverse effect on our business, financial condition and results of operations.**

We conduct a substantial portion of our business in China through our subsidiaries. Accordingly, our results of operations, financial condition, and prospects are to a significant extent affected by economic and political developments in China. In particular, the PRC government continues to exercise significant control over the economic growth of the PRC through the allocation of resources, the control of foreign currency-denominated obligations, the setting of monetary policy, and the provision of preferential treatment to particular industries or companies. The PRC government's economic policies may be adjusted or modified, or applied inconsistently from industry to industry or across different regions of China, and there can be no assurance that any such adjustments or modifications will not have a material adverse effect on our business, financial condition, and results of operations.

The growth of China's economy has slowed in recent years relative to prior periods, and uncertainty remains regarding the pace and trajectory of future economic growth. There have also been ongoing concerns regarding China's relationships with other Asian countries and with the United States, which may result in or intensify potential conflicts relating to territorial disputes, regional security, and trade. See "*Item 3.D — Risk Factors — Certain Risks Relating to Doing Business in China — Escalating U.S.-China trade tensions and tariff measures may materially and adversely affect our business, results of operations, and the price of our securities*" for a more detailed discussion of trade-related risks.

Geopolitical developments — including the ongoing Russia-Ukraine conflict and its effects on global energy markets, supply chains, and the operations of our European customers — continue to create uncertainty for our business. See "*Item 3.D — Risk Factors — Certain Risks Relating to Doing Business in China — The ongoing Russia-Ukraine conflict and related geopolitical tensions may adversely affect the business operations of our suppliers and customers and the terms of our business relationships with them*" for a more detailed discussion of these risks.

Global and regional macroeconomic conditions, including inflationary or deflationary pressures, changes in interest rates, and shifts in consumer and business confidence, may also adversely affect our business. Any continuing or worsening economic slowdown — whether in mainland China, Hong Kong, Europe, or globally, and whether arising from trade conflicts, geopolitical tensions, public health events, or other causes — could significantly reduce demand for the products and services we offer and have a material adverse effect on our business, financial condition, and results of operations.

The Company's results of operations may also be adversely affected by, among other things:

· changes in political, economic, or social conditions in China that affect the markets in which we operate or the demand for our products and services;

· the introduction of measures to control inflation or deflation, or broader macroeconomic stabilization policies affecting credit availability, interest rates, or business investment;

· changes in the rate or method of taxation applicable to the Company or its subsidiaries, including the imposition of confiscatory taxes or other fiscal measures that significantly increase the tax burden on our China operations;

· the imposition of additional restrictions on currency conversion or the remittance of funds overseas, including restrictions on the ability of our subsidiaries to distribute profits to the Company; and

· changes in tariff protection, import or export restrictions, or other trade measures that affect the products we distribute or the markets in which we operate.

We cannot predict the nature, timing, or scope of any future changes in PRC government economic or political policies, or the extent to which such changes may materially and adversely affect our business, financial condition, and results of operations.

**We are subject to International economic and political risks, over which we have little or no control.**

Doing business outside the United States subjects the Company to various risks, including changing economic and political conditions, currency fluctuations and exchange controls, armed conflicts and other geopolitical instability, trade restrictions, transportation disruptions, and unexpected changes in U.S. and foreign laws relating to tariffs, trade restrictions, foreign investment, and taxation. The Company has limited or no control over most of these risks and may be unable to anticipate changes in international economic and political conditions in time to adjust its business practices to avoid or mitigate the adverse effects of any such changes.

In particular, the Company is exposed to risks arising from the ongoing and escalating trade tensions between the United States and mainland China, including the imposition of significant tariff increases on goods imported into the United States from mainland China and retaliatory measures by the PRC government. While the Company does not derive revenues directly from the United States market, U.S.-China trade friction may adversely affect the broader economic environment in mainland China and Hong Kong, affect the purchasing behavior of the Company's customers, disrupt the Company's supply chains, or affect the availability and cost of products that the Company sources from international suppliers. The Company cannot predict the ultimate scope, duration, or further escalation of current trade tensions or their ultimate effect on the Company's business, financial condition, and results of operations.

**Macroeconomic conditions and global economic uncertainty may have a material adverse effect on our business and financial condition.**

Global economic conditions remain subject to significant uncertainty, driven by a combination of factors including elevated inflation in key markets, the downstream effects of monetary policy tightening on credit availability and consumer spending, ongoing geopolitical tensions — including the Russia-Ukraine conflict, Middle East instability, and U.S.-China trade friction — persistent supply chain disruptions, and diverging monetary policies across major economies. These conditions have contributed to heightened volatility in financial markets, tightening of credit conditions, and reduced business and consumer confidence in certain regions, including regions in which the Company operates or in which the Company's customers and suppliers are based.

A deterioration in global or regional economic conditions could adversely affect demand for the Company's products and services, reduce the willingness or ability of the Company's customers to commit to capital expenditure projects, result in pricing pressure, extend sales cycles, or lead to the delay, reduction, or cancellation of orders. In addition, adverse economic conditions may affect the financial stability of the Company's customers, increasing the risk of customer default or insolvency, which could result in increased credit losses and negatively affect the Company's cash flows and results of operations.

Adverse macroeconomic conditions may also impair the Company's ability to access capital markets or obtain financing on favorable terms and could result in increased costs of capital. Furthermore, a prolonged economic slowdown in mainland China, Hong Kong, or the other markets in which the Company and its customers operate could have a disproportionate adverse impact on the Company's business, financial condition, results of operations, and growth prospects.

The Company cannot predict the duration or severity of any current or future period of economic uncertainty or downturn, or the extent to which such conditions may materially and adversely affect the Company's business, financial condition, results of operations, or the market price of its securities.

**Our revenue and net income may be materially and adversely affected by any economic slowdown in China.**

The PRC government has in recent years implemented various measures to manage the rate of economic growth, including adjusting interest rates and deposit reserve ratios for commercial banks and implementing other measures designed to tighten credit and liquidity. These measures have contributed to a moderation of PRC economic growth. According to the National Bureau of Statistics of China, China's real GDP growth rate was 8.1%, 2.9%, 5.2%, 5.0%, and 5.0% in 2021, 2022, 2023, 2024, and 2025, respectively.

Any continuing or worsening slowdown in the PRC economy could significantly reduce domestic commerce and investment activity in China, including in the environmental technology and water treatment sectors in which the Company operates. An economic downturn — whether actual or perceived — a further decrease in economic growth rates, or an otherwise uncertain economic outlook in China or any other market in which the Company operates could have a material adverse effect on the Company's business, financial condition, and results of operations.

**We can provide no assurance that we will not be affected by higher rates of inflation in the future.**

The inflation rate in China, as measured by the consumer price index, was 0.99%, 1.96%, 0.24%, 0.24%, and nil in 2021, 2022, 2023, 2024, and 2025, respectively. The Company cannot determine the precise effect of inflation on its operations The Company does not believe that inflation has had a material effect on its revenues or results of operations during the periods covered by this Annual Report. However, there can be no assurance that the Company will not be materially affected by higher rates of inflation in future periods.

If the rate of inflation in China increases, the PRC government may introduce measures intended to reduce inflationary pressures. Any such measures may not be successful in reducing or slowing the rate of inflation, and efforts by the PRC government to curb inflation may simultaneously curb economic growth, increase the Company's overhead costs, and adversely affect the Company's revenues. Sustained or increased inflation in mainland China could have a material adverse impact on the broader PRC economy and could materially and adversely affect the Company's business, financial condition, and results of operations.

**The PRC legal system embodies uncertainties which could limit the available legal protections and expand the government's power.**

The PRC legal system is a civil law system based on written statutes. Unlike common law systems, decided cases have limited precedential value in the PRC. Since 1979, the PRC government has promulgated a comprehensive and evolving system of laws and regulations governing economic matters. The overall effect of legislation over the past four decades has significantly enhanced the protections afforded to various forms of foreign investment in China. However, these laws, regulations, and legal requirements change frequently, often with little advance notice, and their interpretation and enforcement involve significant uncertainty.

The Company may need to resort to administrative and court proceedings to enforce legal protections available to it by law or contract. However, since PRC administrative and court authorities have significant discretion in interpreting and implementing statutory and contractual terms, it may be more difficult to evaluate the outcome of administrative and court proceedings and the level of legal protection available to the Company than would be the case in more developed legal systems. Such uncertainties — including the potential inability to enforce contracts — could materially and adversely affect the Company's business and operations.

Furthermore, the PRC legal system is based in part on government policies and internal rules, some of which are not published on a timely basis or at all, and which may have retroactive effect. As a result, the Company may not be aware of any violation of these policies and rules until after the violation has occurred. Any litigation in China may be protracted and result in substantial costs and diversion of resources and management attention. Intellectual property rights and confidentiality protections in China may not be as effective as those available in the United States or other jurisdictions.

The Company cannot predict the effect of future developments in the PRC legal system, including the promulgation of new laws, changes to existing laws, or changes in the interpretation or enforcement thereof. These uncertainties could limit the legal protections available to the Company and its shareholders.

**You may experience difficulties in effecting service of legal process, enforcing foreign judgments or bringing original actions in China based on United States or other foreign laws against us, our management or the experts named in this Annual Report.**

The Company conducts a portion of its operations in mainland China and Hong Kong, and a portion of its assets are located in these jurisdictions. The Company's principal offices are located in Hong Kong, and certain of the Company's directors and executive officers reside in Hong Kong and mainland China. As a result, it may not be possible to effect service of process within the United States or elsewhere outside China upon some of the Company's directors and senior executive officers, including with respect to matters arising under U.S. federal securities laws or applicable state securities laws.

The Company understands that the PRC does not currently have treaties with the United States or many other countries providing for the reciprocal recognition and enforcement of court judgments. As a result, recognition and enforcement in China of judgments of U.S. courts in connection with any action, including actions predicated upon the civil liability provisions of U.S. federal and state securities laws, may be difficult or impossible. Investors may therefore have limited recourse against the Company, its directors, and its executive officers for matters arising under U.S. securities laws.

**Regulations relating to offshore investment activities by PRC residents may increase the administrative burden we face and create regulatory uncertainties that could restrict our overseas and cross-border investment activity, and a failure by our shareholders who are PRC residents to make any required applications and filings pursuant to such regulations may prevent us from being able to distribute profits and could expose our PRC resident shareholders to liability under PRC law.**

China's State Administration of Foreign Exchange ("SAFE") promulgated the Circular on Relevant Issues Concerning Foreign Exchange Control on Domestic Residents' Offshore Investment and Financing and Roundtrip Investment through Special Purpose Vehicles ("SAFE Circular No. 37") in July 2014. SAFE Circular No. 37 requires PRC residents to register with local branches of SAFE in connection with their direct establishment or indirect control of an offshore entity for the purpose of overseas investment and financing using legally owned assets or equity interests in domestic enterprises or offshore assets or interests — referred to in SAFE Circular No. 37 as a "special purpose vehicle." The term "control" under SAFE Circular No. 37 is broadly defined to include operation rights, beneficiary rights, or decision-making rights acquired by PRC residents in offshore special purpose vehicles or PRC companies through acquisition, trust arrangements, proxy arrangements, voting rights, share repurchase, convertible bonds, or other arrangements. SAFE Circular No. 37 further requires amendment to the registration in the event of any changes to the basic information of the special purpose vehicle — such as a change in a PRC resident individual shareholder, or a change in the entity's name or operating period — or any significant changes with respect to the special purpose vehicle, such as an increase or decrease in capital contributed by PRC individuals, a share transfer or exchange, a merger, a division, or any other material event.

In February 2015, SAFE issued SAFE Circular No. 13, which took effect on June 1, 2015. SAFE Circular No. 13 delegated to qualified banks the authority to process the registration of PRC residents' investments in special purpose vehicles pursuant to SAFE Circular No. 37, except that PRC residents who have failed to comply with SAFE Circular No. 37 remain subject to the jurisdiction of the local SAFE branch and must submit any supplementary registration application directly to the local SAFE branch.

If the PRC resident shareholders of the Company's offshore holding company do not complete their registration with the relevant local SAFE branch, the Company's PRC subsidiaries may be prohibited from distributing their profits and proceeds from any reduction in capital, share transfer, or liquidation to the offshore holding company, and the offshore holding company may be restricted in its ability to contribute additional capital to its PRC subsidiaries. Failure to comply with the SAFE registration and amendment requirements described above could also result in liability under PRC law for evasion of applicable foreign exchange restrictions.

The Company has requested all PRC residents known to it who hold a direct or indirect interest in the Company to make the necessary applications, filings, and amendments as required under SAFE Circular No. 37 and other related rules. However, the Company may not be aware of the identities of all PRC residents who hold a direct or indirect interest in the Company, and the Company cannot provide any assurance that these PRC residents will comply with its request to make or obtain the applicable registrations or otherwise comply with the requirements of SAFE Circular No. 37 or other related rules. The failure or inability of the Company's PRC resident shareholders to comply with the registration requirements described above may subject the Company to fines and legal sanctions, restrict its cross-border investment activities, limit the ability of its PRC subsidiaries to distribute dividends and other proceeds to the Company, and prevent the Company from injecting additional capital into its PRC subsidiaries. Failure to comply with the applicable foreign exchange registration requirements could also result in liability under PRC law for circumventing applicable foreign exchange restrictions. As a result, the Company's business operations and its ability to distribute profits to shareholders could be materially and adversely affected.

**If the custodians or authorized users of controlling non-tangible assets of our Company, including our corporate chops and seals, fail to fulfill their responsibilities, or misappropriate or misuse these assets, our business and operations could be materially and adversely affected.**

Under PRC law, legal documents for corporate transactions are executed using the chops or seals of the signing entity or with the signature of a legal representative whose designation is registered with the relevant local authority.

Although the Company generally uses chops to enter into contracts, the designated legal representatives of each of the Company's PRC subsidiaries have the apparent authority to enter into contracts on behalf of those entities without chops and to legally bind those entities. All designated legal representatives of the Company's PRC subsidiaries are members of the Company's senior management team who have entered into employment agreements with the Company or its PRC subsidiaries under which they agree to abide by their fiduciary duties and other obligations owed to the Company. To maintain the physical security of the chops of its PRC entities, the Company generally stores these items in secured locations accessible only by authorized personnel in the legal or finance department of each relevant subsidiary. Although the Company monitors such authorized personnel, there can be no assurance that such procedures will prevent all instances of abuse or negligence.

If any authorized personnel misuse or misappropriate the Company's corporate chops or seals, the Company could encounter difficulties in maintaining control over the relevant entities and experience significant disruption to its operations. If a designated legal representative obtains unauthorized control of the chops in an effort to gain control over any of the Company's PRC subsidiaries, the Company or the relevant PRC subsidiary would need to pass a new shareholder or board resolution to designate a new legal representative and would need to take legal action to seek the return of the chops, apply for replacement chops with the relevant authorities, or otherwise seek legal redress for the violation of the representative's duties to the Company. Any such action could involve significant time and resources and divert management attention from the Company's regular business operations. In addition, the affected entity may not be able to recover corporate assets that are sold or transferred without authorization in the event of such a misappropriation, particularly where a transferee relies on the apparent authority of the relevant representative and acts in good faith.

**The PRC government imposes controls on currency conversion and the remittance of funds out of China, which may restrict the Company's ability to transfer cash and pay dividends.**

The PRC government imposes controls on the convertibility of Renminbi ("RMB") into foreign currencies and, in certain cases, on the remittance of currency out of China. A substantial portion of the Company's revenues from its PRC operations are denominated in RMB. Under existing PRC foreign exchange regulations, payments of current account items — including profit distributions, interest payments, and trade and service-related foreign exchange transactions — can be made in foreign currencies without prior approval, subject to compliance with applicable procedural requirements. However, approval from, or registration with, the relevant PRC governmental authorities is required where RMB is to be converted into foreign currency and remitted out of China to pay capital account expenses, such as the repayment of loans denominated in foreign currencies. The PRC government may also, at its discretion, restrict access to foreign currencies for current account transactions in the future.

Under PRC laws and regulations, the Company's PRC subsidiaries may only pay dividends out of their accumulated after-tax profits as determined in accordance with PRC accounting standards and regulations. In addition, each of the Company's PRC subsidiaries is required under PRC law to set aside at least 10% of its after-tax profits each year — after making up for any prior years' accumulated losses — to fund statutory reserves, until the aggregate amount of such reserves reaches 50% of the subsidiary's registered capital. The Company's PRC subsidiaries may only distribute dividends upon approval of their respective shareholders after satisfying these statutory reserve requirements.

As a result of these restrictions, the Company's PRC subsidiaries are limited in their ability to transfer cash or assets to the Company. While the Company does not currently require dividends, loans, or advances from its PRC subsidiaries for working capital or other funding purposes, the Company may in the future require additional cash resources from its PRC subsidiaries due to changes in business conditions, to fund future acquisitions or development activities, or to fund dividends or distributions to the Company's shareholders. To the extent that cash held within the Company's PRC subsidiaries is needed to fund operations or other uses outside of the PRC, the ability to transfer such funds may be subject to intervention, restrictions, or limitations imposed by the PRC government. Any such restrictions could materially and adversely affect the Company's liquidity, financial condition, and ability to pay dividends to its shareholders.

**The Company is exposed to foreign currency risk.**

The Company operates in Hong Kong and mainland China and conducts trade with both local and overseas customers and suppliers. As a result, the Company is exposed to foreign exchange risk arising from various currency exposures, primarily with respect to transactions denominated in Hong Kong Dollars, Renminbi, U.S. Dollars, Japanese yen, and euros. Foreign exchange risk arises from committed and unmatched future commercial transactions — such as confirmed import purchase orders and sales orders — as well as from recognized assets and liabilities and the Company's net investment in its PRC operations.

The Company does not currently maintain a hedging program with respect to its foreign currency exposure. Significant fluctuations in exchange rates between the U.S. Dollar and the currencies in which the Company transacts business could have a material adverse effect on the Company's business, financial condition, and results of operations. Please refer to "Item 11 — Quantitative and Qualitative Disclosures About Market Risk" for a more detailed description of the Company's foreign currency risk exposure.

**Because our revenues are generated in Renminbi and our results are reported in U.S. Dollars, fluctuations in the value of the Renminbi could negatively impact our results of operations.**

The value of the Renminbi against the U.S. Dollar and other currencies is affected by changes in China's political and economic conditions and by China's foreign exchange policies, among other things. The PRC government has historically maintained a managed floating exchange rate system under which the Renminbi is permitted to fluctuate within a regulated band against a basket of foreign currencies. The RMB/USD exchange rate has experienced significant volatility in recent years.

In 2021, the Renminbi appreciated against the U.S. Dollar by approximately 2.3%, closing the year at approximately RMB 6.38 per U.S. Dollar. This appreciation reversed sharply in 2022, when the Renminbi depreciated by approximately 9.2% against the U.S. Dollar — one of the most significant single-year depreciations in recent history — driven in large part by the divergence between aggressive U.S. Federal Reserve interest rate tightening and the People's Bank of China's relatively accommodative monetary policy stance, closing the year at approximately RMB 6.96 per U.S. Dollar. Depreciation pressure continued in 2023 and 2024, with the Renminbi weakening by approximately 1.7% and 1.5% respectively against the U.S. Dollar in those years, reflecting persistent concerns about the pace of China's economic recovery and sustained U.S. Dollar strength. In 2025, the Renminbi appreciated by approximately 4.2% for the full year against the U.S. Dollar amid a softer U.S. Dollar and improving market expectations for China's economy, closing the year at approximately RMB 6.99 per U.S. Dollar. For the full year 2025, the annual average exchange rate was RMB 7.1429 per U.S. Dollar, representing a slight depreciation of 0.3% compared to 2024.

These fluctuations reflect the influence of a range of factors, including macroeconomic conditions in China and the United States, PRC monetary policy and the People's Bank of China's daily fixing mechanism, U.S. Federal Reserve policy decisions and their effect on U.S. dollar strength, and broader geopolitical developments including U.S.-China trade tensions. The ongoing escalation of U.S.-China trade tensions — including the significant tariff increases announced in 2025 — may add further uncertainty to the RMB/USD exchange rate outlook in future periods.

It is difficult to predict how market forces or PRC or U.S. government policy may impact the exchange rate between the Renminbi and the U.S. Dollar in the future. There remains significant international pressure on the PRC government to adopt a more flexible currency policy, which could result in greater fluctuations of the Renminbi against the U.S. Dollar. With the development of the foreign exchange market and progress towards interest rate liberalization and Renminbi internationalization, the PRC government may in the future announce further changes to the exchange rate system, and there is no guarantee that the Renminbi will not appreciate or depreciate significantly in value against the U.S. Dollar in the future.

Significant revaluation of the Renminbi may have a material and adverse effect on your investment. To the extent that we need to convert U.S. Dollar into Renminbi for our operations, appreciation of the Renminbi against the U.S. Dollar would have an adverse effect on the Renminbi amount we would receive from the conversion. Conversely, if we decide to convert our Renminbi into U.S. Dollar for the purpose of making payments for dividends on our ordinary shares or for other business purposes, appreciation of the U.S. Dollar against the Renminbi would have a negative effect on the U.S. Dollar amount available to us. In addition, appreciation or depreciation in the value of the Renminbi relative to U.S. Dollar would affect our financial results reported in U.S. Dollar terms regardless of any underlying change in our business or results of operations.

Hedging options available in China to reduce exposure to exchange rate fluctuations remain limited. To date, we have not entered into any hedging transactions in an effort to reduce our exposure to foreign currency exchange risk. While we may decide to enter into hedging transactions in the future, the availability and effectiveness of these hedges may be limited and we may not be able to adequately hedge our exposure, or at all. In addition, our currency exchange losses may be magnified by PRC exchange control regulations that restrict our ability to convert Renminbi into foreign currency. As a result, fluctuations in exchange rates may have a material adverse effect on your investment.

**Escalating U.S. - China trade tensions and tariff measures may materially and adversely affect our business, results of operations, and the price of our securities.**

In recent years, trade and geopolitical tensions between the United States and China have escalated significantly. Beginning with the imposition of tariffs under Section 301 of the Trade Act of 1974 and continuing through successive rounds of tariff escalation, the United States has imposed substantial additional tariffs on a wide range of goods imported from China. China has responded with retaliatory tariffs and other trade countermeasures targeting goods of U.S. origin imported into China. As of the date of this Annual Report, these tariff measures remain largely in effect and the broader U.S.-China trade relationship continues to be subject to material uncertainty and further potential escalation.

A significant portion of our business consists of distributing products of U.S. origin to customers in mainland China. The impact of existing tariff measures is already being reflected in our operating results — our sales to customers in mainland China of U.S.-origin products decreased by approximately 50% during Fiscal 2025 as compared to Fiscal 2024, which we attribute in part to the effect of tariff-related uncertainty on customer purchasing behavior. As China imposes additional or higher tariffs on goods of U.S. origin — including the categories of products we distribute, such as laboratory instruments, analyzers, water treatment equipment, and related supplies — our Chinese customers may reduce or delay their purchases of such products, seek to substitute locally manufactured or non-U.S.-origin alternatives, or negotiate more favorable commercial terms. Any of these outcomes could result in a reduction in our sales volumes, compression of our profit margins, and a material adverse effect on our revenues and results of operations.

---

In addition, the imposition of tariffs and other trade restrictions by any country or region in which we operate could increase our costs, reduce the competitiveness of the prices of the products we distribute, restrict our ability to source products from existing suppliers, or adversely affect our ability to ship and deliver products to our customers in a timely manner. Any such development could harm our business, financial condition, and results of operations.

The current tariff and trade restriction environment also creates significant uncertainty for our medium- and long-term business planning. It is difficult to predict the future trajectory of U.S.-China trade relations, including whether existing tariff measures will be maintained, increased, reduced, or replaced with other forms of trade restrictions. Any further escalation of U.S.-China trade tensions — including through the imposition of additional tariffs, export controls, investment restrictions, sanctions, or other trade countermeasures — could further adversely affect our business and the markets in which we operate.

Political and trade friction between the United States and China could also materially and adversely affect investor sentiment toward companies with significant operations or commercial exposure in China, which could result in increased volatility in or a decline in the market price of our securities regardless of our operating performance.

**The PRC anti-foreign sanctions law may create conflicts of legal obligations for the company and could adversely affect our business and operations.** 

In June 2021, China enacted the Law of the People's Republic of China on Countering Foreign Sanctions (the "Anti-Foreign Sanctions Law"). The Anti-Foreign Sanctions Law grants the PRC government broad authority to take countermeasures against foreign states that the PRC government determines have adopted discriminatory restrictive measures — including sanctions — against Chinese citizens or organizations. Countermeasures available to the PRC government under the Anti-Foreign Sanctions Law include, among other things: freezing the assets of, and prohibiting transactions with, individuals and entities that directly or indirectly participate in the formulation, decision-making, or implementation of the relevant foreign sanctions; and restricting or prohibiting the activities of companies and individuals that comply with foreign sanctions measures targeting China.

The Anti-Foreign Sanctions Law creates a potential conflict of obligations for companies — such as Euro Tech — that operate across both U.S. and Chinese jurisdictions. Specifically, where the United States imposes sanctions that require U.S.-listed companies or distributors of U.S.-origin products to restrict their activities in China, compliance with those U.S. sanctions requirements could simultaneously expose the Company to liability or countermeasures under the Anti-Foreign Sanctions Law. Conversely, compliance with the Anti-Foreign Sanctions Law could expose the Company to liability under U.S. law. There is currently no clear legal mechanism for resolving such conflicts of obligations, and the resolution of any such conflict could require the Company to choose between compliance with U.S. law and compliance with PRC law.

The Anti-Foreign Sanctions Law may also affect the Company's relationships with its suppliers and customers. Suppliers of U.S.-origin products distributed by the Company into China may themselves be subject to U.S. sanctions compliance requirements that conflict with the Anti-Foreign Sanctions Law. Similarly, Chinese customers of the Company may be affected by U.S. sanctions, which could restrict the Company's ability to continue to distribute products to those customers. Any such development could result in a disruption to our supply chain, the loss of key customers or suppliers, or a material adverse effect on our revenues and results of operations.

The full scope and application of the Anti-Foreign Sanctions Law — including the criteria for determining which foreign sanctions measures trigger countermeasures, and the categories of companies and individuals subject to restriction — continues to evolve and remains subject to significant uncertainty. The PRC government has broad discretion in implementing the Anti-Foreign Sanctions Law, and it is not possible to predict when or how it may be applied in circumstances that affect the Company, its suppliers, or its customers.

There can be no assurance that the Anti-Foreign Sanctions Law, or any future PRC legislation with similar effect, will not be applied in a manner that materially and adversely affects our business, financial condition, and results of operations, or that we will be able to comply simultaneously with both U.S. and PRC legal requirements in the event of a conflict.

**U.S. export control laws and regulations, including restrictions on the export of certain products to China, may adversely affect our ability to distribute products and could have a material adverse effect on our business and results of operations.** 

As a distributor of products of U.S. origin — including laboratory instruments, analyzers, water treatment equipment, and related supplies — into China, the Company is subject to, and its business is materially affected by, U.S. export control laws and regulations. These include, among others, the Export Administration Regulations ("EAR") administered by the Bureau of Industry and Security ("BIS") of the U.S. Department of Commerce, and the regulations administered by the Office of Foreign Assets Control ("OFAC") of the U.S. Department of the Treasury. Compliance with these laws and regulations is the responsibility of the Company, its U.S.-based suppliers, and in certain cases, the end-users of the products the Company distributes.

BIS Entity List and Restricted Party Risks

BIS maintains an Entity List of foreign persons, organizations, and companies that are subject to specific license requirements for the export, re-export, or transfer of items subject to the EAR. Additions to the Entity List can be made at any time and without advance notice. If any of our existing or prospective customers in mainland China are added to the Entity List or any other BIS restricted party list, we may be prohibited from distributing products of U.S. origin to those customers, or our U.S.-based suppliers may be required to obtain export licenses — which may not be granted — before selling to us for distribution to those customers. In recent years, BIS has significantly expanded the Entity List to include a large number of Chinese companies across a wide range of industries, including the scientific instruments, analytical equipment, and environmental technology sectors that are directly relevant to our business.

Export Control Classification and License Requirements

Certain products that the Company distributes — including laboratory instruments, spectrometers, analyzers, and other advanced analytical equipment — may be subject to export control classification under the EAR and may require export licenses for shipment to China or to certain end-users in China. The export licensing requirements applicable to specific products may change as a result of updates to the Commerce Control List ("CCL"), changes in U.S. government policy toward China, or the reclassification of products by BIS. If products that we currently distribute without an export license are reclassified or become subject to new licensing requirements, we or our U.S.-based suppliers may be required to obtain export licenses that may not be available, may be subject to significant delays, or may be granted subject to conditions that restrict the categories of permitted end-users.

De Minimis Exemption

Under the EAR, products that contain a de minimis percentage of U.S.-origin controlled content may qualify for an exemption from U.S. export controls when exported to certain destinations, including China. Changes to the de minimis thresholds applicable to China — including potential reductions in the applicable de minimis percentage — could subject a broader range of products to U.S. export control requirements and could restrict our ability to distribute such products to customers in China without obtaining export licenses. The U.S. government has in recent years moved to tighten de minimis thresholds and related foreign-produced direct product rules applicable to China, and further changes in this area cannot be ruled out.

Supplier Compliance and Contractual Restrictions

In addition to our own compliance obligations, our U.S.-based suppliers are themselves subject to U.S. export control laws and may impose contractual restrictions on the distribution of their products to certain end-users, jurisdictions, or applications as a condition of their supply arrangements with us. If a supplier determines that compliance with U.S. export control requirements prevents it from supplying products to us for distribution in China, or imposes conditions on such supply that we are unable to satisfy, we may lose access to key product lines, which could materially and adversely affect our revenues and results of operations.

General Compliance Risk

Violations of U.S. export control laws and regulations can result in significant civil and criminal penalties, including substantial fines, denial of export privileges, and debarment from U.S. government contracting. Even where the Company itself is in compliance with applicable export control requirements, changes in U.S. government policy toward China — including the expansion of export controls to additional product categories, the addition of Chinese entities to restricted party lists, or the tightening of de minimis and foreign-produced direct product rules — could materially reduce the range of products we are able to distribute in China, limit our customer base, or increase our compliance costs.

We cannot predict the future trajectory of U.S. export control policy with respect to China, or the extent to which new or expanded export control measures may adversely affect our ability to source and distribute products of U.S. origin to our customers in mainland China. There can be no assurance that changes in U.S. export control laws and regulations will not have a material adverse effect on our business, financial condition, and results of operations.

**Chinese regulatory authorities could disallow our holding company structure.**

The Company is a holding company incorporated in the BVI and does not itself conduct any active business operations. The Company owns 100% of the shares of Euro Tech Global Pte. Limited ("Euro Tech Global"), which in turn owns 100% of the shares of Euro Tech (Far East) Limited ("Far East"). Far East holds the following equity interests in its subsidiaries and associated companies:

---

| |
|:---|
| 100% of the equity of Euro Tech Trading (Shanghai) Limited ("ETTS") in mainland China; |
| 58% of the equity of each of PACT Environmental Technology Pte. Ltd. ("Pact Singapore") in Singapore, Yixing Pact Environmental Technology Co., Ltd. ("Yixing") in mainland China, and Pact Asia Pacific Limited ("Pact") in the BVI; and |
| 19.42% of the equity of Blue Sky (Holdings) Limited ("Blue Sky") in mainland China. |

---

ETTS and Pact are no longer engaged in active business operations. Euro Tech Global, Far East, Pact Singapore, Yixing, and Blue Sky are engaged in active business operations.

As of the date of this Annual Report, PRC law does not expressly prohibit or restrict the Company from holding the equity interests described above. However, there can be no assurance that PRC regulatory authorities will not in the future disallow the Company's holding company structure, or otherwise prohibit or restrict the Company from holding the equity of any of its subsidiaries or associated companies. PRC laws and regulations are subject to frequent change, and the interpretation and enforcement thereof involve significant uncertainty. If PRC regulatory authorities were to disallow the Company's holding company structure or impose restrictions on the Company's ability to hold equity interests in its subsidiaries or associated companies, this would likely result in a material adverse change in the Company's operations and could cause the value of the Company's securities to decline significantly or become worthless.

**As a holding company, Euro Tech's ability to pay dividends and meet its other obligations depends entirely on distributions from its subsidiaries, which are subject to significant statutory and regulatory restrictions.** 

Euro Tech is a holding company and does not itself conduct any revenue-generating operations. All of the Company's business is conducted through its subsidiaries, principally Euro Tech (Far East) Limited in Hong Kong and Yixing Pact Environmental Technology Co., Ltd. in mainland China. As a holding company, Euro Tech's ability to pay dividends to its shareholders, meet its operating expenses, and satisfy any other financial obligations depends entirely on its ability to receive dividends, distributions, loans, or other payments from its subsidiaries.

---

| |
|:---|
| 23 |
| *[**Table of Contents**](#TOC)* |

---

The ability of the Company's subsidiaries to make distributions to Euro Tech is subject to significant statutory and regulatory restrictions, including the following:

---

| |
|:---|
| PRC statutory reserve requirements: Under PRC laws and regulations, each of the Company's subsidiaries incorporated in mainland China is required to set aside at least 10% of its after-tax profits each year — after making up for any prior years' accumulated losses — to fund certain statutory reserves, until the aggregate amount of such fund reaches 50% of its registered capital. Profits set aside for statutory reserves are not available for distribution. |
| Shareholder approval requirements: The Company's PRC subsidiaries may only distribute dividends upon approval of their respective shareholders, and only after meeting the applicable PRC requirements for appropriation to statutory reserves. This approval process may cause delays in the upstreaming of profits and may result in profits being retained at the subsidiary level for extended periods. |
| PRC foreign exchange controls: The PRC government imposes controls on the convertibility of Renminbi into foreign currencies and, in certain cases, on the remittance of currency out of China. The Company's PRC subsidiaries are required to comply with applicable foreign exchange regulations before distributing dividends or making other payments to the Company in foreign currency, which may restrict or delay the timing and amount of distributions the Company receives from its PRC subsidiaries. See "*Item 3.D — Risk Factors — The PRC government imposes controls on currency conversion and the remittance of funds out of China, which may restrict the Company's ability to transfer cash and pay dividends.*" for a more detailed discussion. |
| SAFE registration requirements: Under SAFE Circular No. 37 and related regulations, failure by the Company's PRC resident shareholders to complete required SAFE registrations could result in the Company's PRC subsidiaries being prohibited from distributing profits to the Company and restrict the Company's ability to contribute additional capital to those subsidiaries. See "*Item 3.D — Risk Factors — Regulations relating to offshore investment activities by PRC residents may increase the administrative burden we face and create regulatory uncertainties that could restrict our overseas and cross-border investment activity, and a failure by our shareholders who are PRC residents to make any required applications and filings pursuant to such regulations may prevent us from being able to distribute profits and could expose our PRC resident shareholders to liability under PRC law*." for a more detailed discussion. |
| Retained earnings requirement: PRC laws and regulations permit PRC companies to pay dividends only out of their accumulated retained earnings as determined in accordance with PRC accounting standards and regulations. If any of the Company's PRC subsidiaries has insufficient retained earnings, it will be unable to pay dividends to the Company regardless of the amount of cash it holds. |

---

As a result of these restrictions, the Company may not be able to receive sufficient distributions from its subsidiaries to fund its operating expenses, pay dividends to shareholders, or meet its other obligations in a timely manner, or at all. Even if the Company's subsidiaries have sufficient profits to distribute, regulatory restrictions may prevent or delay the upstreaming of those profits to the Company.

In addition, to the extent that cash in the business is held at the subsidiary level — particularly within PRC entities — such funds may not be freely available to fund operations or other uses outside of the PRC. There can be no assurance that the statutory and regulatory restrictions described above will not be expanded or tightened in the future in ways that further limit the ability of the Company's subsidiaries to make distributions to Euro Tech.

Investors in Euro Tech's ordinary shares should be aware that they hold equity interests in a holding company whose ability to generate returns for shareholders is entirely dependent on the financial performance of its subsidiaries and their ability to make distributions upstream through the corporate structure in compliance with applicable law. The Company's ability to pay dividends to its shareholders is not guaranteed, and there have been fiscal years in which the Company did not pay any dividends. See "Item 8.A — Consolidated Statements and Other Financial Information — Dividend Policy" for additional information on the Company's dividend history and policy.

**Our failure to comply with PRC cybersecurity and data protection laws and regulations — including the cyber data security administration regulations effective January 1, 2025 — could lead to government enforcement actions, significant penalties, and an adverse effect on our operating results.**

Regulatory authorities in China have enacted, and continue to enact, a comprehensive and evolving framework of laws and regulations concerning cybersecurity, data protection, personal information, and cross-border data transfer. These laws and regulations are complex, frequently updated, and their interpretation and application remain uncertain and subject to change. Our failure — or perceived failure — to comply with any of these requirements could expose us to government enforcement actions, significant penalties, restrictions on our business operations, and reputational harm.

PRC Cybersecurity Law

The PRC Cybersecurity Law, which originally took effect in June 2017, was amended by the Standing Committee of the National People's Congress on October 28, 2025, with the amended law taking effect on January 1, 2026 (as amended, the "PRC Cybersecurity Law"). The PRC Cybersecurity Law governs the construction, operation, maintenance, and use of networks in China and subjects network operators to various security protection obligations. The PRC Cybersecurity Law also provides that personal information and important data collected and generated by operators of critical information infrastructure ("CII") in the course of their operations in the PRC must be stored within the PRC, and imposes heightened regulation and additional security obligations on such operators. Among the key changes introduced by the 2025 amendment, the revised PRC Cybersecurity Law significantly strengthens the legal liabilities applicable to violations of cybersecurity obligations, including by imposing materially higher penalties for non-compliance.

The Company believes that it is neither a network operator nor an operator of CII within the meaning of the PRC Cybersecurity Law, and that it is in compliance with the PRC Cybersecurity Law as currently in effect. However, the interpretation and enforcement of the PRC Cybersecurity Law involve significant uncertainty, and there can be no assurance that the PRC government will not take a different view of the Company's compliance status. If the Company is determined by the PRC government to have failed to comply with the PRC Cybersecurity Law, the Company could be subject to materially higher fines and penalties than were applicable under the original law, suspension of business operations, and revocation of business licenses, any of which could have a material adverse effect on the Company's business, financial condition, and results of operations. The Company will continue to monitor developments in PRC cybersecurity regulation and will take such steps as it determines to be necessary or appropriate to maintain compliance with applicable requirements.

PRC Data Security Law

The PRC Data Security Law, which took effect on September 1, 2021, establishes a tiered system for data protection based on the importance of the relevant data. Data categorized as "important data" — as determined by governmental authorities through published catalogs — is required to be treated with a higher level of protection. Operators processing "important data" are required to appoint a data security officer and a dedicated management department, and to conduct periodic risk assessments and file assessment reports with the relevant regulatory authorities. The Measures for Security Assessment for Outbound Data Transfer, which took effect on September 1, 2022, require mandatory CAC security review prior to any cross-border transfer of "important data."

Cybersecurity Review Measures

The Cybersecurity Review Measures, which became effective on February 15, 2022, subject critical information infrastructure operators that purchase network products and services, or that conduct data processing activities affecting or potentially affecting national security, to cybersecurity review. The Cybersecurity Review Measures also extend cybersecurity review requirements to internet platform operators that hold personal information of more than one million users and intend to list securities in a foreign country. Our corporate customers in mainland China are businesses rather than individual consumers, and we do not currently hold — and do not anticipate collecting — personal information of more than one million users. We therefore do not believe we are currently subject to the Cybersecurity Review Measures as an internet platform operator. However, there can be no assurance that our assessment will not be challenged by the relevant authorities.

Cyber Data Security Administration Regulations

On September 24, 2024, the State Council of China issued the Cyber Data Security Administration Regulations (the "Data Security Administration Regulations"), which came into effect on January 1, 2025. The Data Security Administration Regulations represent a significant development in China's data governance framework and impose new obligations on data processors operating in China, including the following:

· Risk assessments prior to sharing important data: Data processors are required to conduct a risk assessment before providing, entrusting, or jointly processing important data with third parties, except where such actions are necessary to fulfill statutory duties or obligations.

· CAC security assessment for overseas data transfers: Data processors operating within China that need to transfer important data collected or generated domestically to overseas recipients must undergo a data export security assessment organized by the CAC prior to effecting any such transfer.

The full scope of application, implementation procedures, and enforcement priorities of Data Security Administration Regulations are still developing. There remains meaningful uncertainty regarding the practical interpretation and application of the Data Security Administration Regulations, particularly with respect to the definition of "important data" and the thresholds and procedures for triggering the CAC security assessment requirement for overseas data transfers.

Based on our current assessment, we do not believe that we process "important data" as that term is understood under the applicable regulatory framework, as our business primarily involves the distribution of water treatment equipment, laboratory instruments, analyzers, and related products to corporate customers, and we do not collect or process large volumes of personal data or data in sectors typically identified as generating "important data." However, given the evolving nature of the regulatory framework and the absence of comprehensive published guidance on what constitutes "important data" in our sector, we cannot provide assurance that we will not be determined by the relevant authorities to be subject to the requirements of the Data Security Administration Regulations, including the risk assessment and CAC security assessment requirements.

Personal Information Protection Law

The Personal Information Protection Law ("PIPL"), which took effect on November 1, 2021, integrates various rules with respect to personal information rights and privacy protection. The PIPL applies to the processing of personal information within mainland China as well as certain personal information processing activities outside mainland China, including those conducted for the purpose of providing products or services to natural persons within China or for the analysis or assessment of the conduct of natural persons within China.

General Compliance Risk

The cybersecurity and data protection regulatory framework in China is relatively new, rapidly evolving, and subject to significant uncertainty in interpretation and implementation. Any change in, or enhanced enforcement of, laws and regulations relating to privacy, data protection, and information security could substantially increase our compliance costs, limit the use or adoption of our products and services, or require changes to our operations. We cannot assure you that we will be in full compliance with all applicable cybersecurity and data protection laws and regulations at all times, and we may be ordered to rectify or cease any activities deemed non-compliant by governmental authorities, and may be subject to fines and other government sanctions, which could materially and adversely affect our business, financial condition, and results of operations.

In particular, given the uncertainties surrounding the interpretation and implementation of these laws and regulations, we cannot rule out the possibility that we, or certain of our customers or suppliers, may be deemed to be a critical information infrastructure operator or an operator processing "important data." If we are deemed to be a critical information infrastructure operator, our purchase of network products or services — if determined to affect or potentially affect national security — may be subject to cybersecurity review, and we may face restrictions on our ability to purchase products and services from our suppliers or provide products and services to our customers pending completion of that review. Any failure or delay in completing required cybersecurity review procedures could result in fines of up to ten times the purchase price of the relevant network products or services. If we are deemed to be an operator processing "important data," we will be required to identify and classify such data, monitor applicable government-issued data catalogs, conduct periodic risk assessments, comply with reporting obligations, and pass government security review prior to sharing such data with overseas recipients, which could have a material adverse effect on our results of operations and business prospects.

**PRC national security legislation and political developments in Hong Kong may adversely affect our business and operations.** 

The Company's executive and principal offices are located in Hong Kong, and our principal operating subsidiary, Euro Tech (Far East) Limited, is incorporated and operates in Hong Kong. Hong Kong is a Special Administrative Region of the People's Republic of China. Pursuant to the Sino-British Joint Declaration on the Question of Hong Kong (the "Joint Declaration") and the Basic Law of Hong Kong (the "Basic Law"), Hong Kong is afforded a high degree of autonomy except in matters of foreign affairs and defense, and maintains a legal system based on common law that is distinct from that of mainland China. This framework has historically been referred to as "one country, two systems".

In recent years, the legal and political environment in Hong Kong has undergone significant change. In June 2020, the Standing Committee of the National People's Congress enacted the Law of the People's Republic of China on Safeguarding National Security in the Hong Kong Special Administrative Region (the "National Security Law" or "NSL"). The NSL introduced four categories of offenses — secession, subversion, terrorist activities, and collusion with foreign forces — each carrying significant criminal penalties, including in certain cases a maximum sentence of life imprisonment. The NSL also established new enforcement mechanisms and authorities, including the Committee for Safeguarding National Security and the Office for Safeguarding National Security of the Central People's Government in Hong Kong.

In March 2024, the Legislative Council of Hong Kong enacted legislation under Article 23 of the Basic Law (the "Article 23 Legislation"), which had been required since Hong Kong's handover in 1997 but had not previously been enacted. The Article 23 Legislation introduced additional national security offenses, including treason, insurrection, sabotage, external interference, and theft of state secrets, and expanded certain existing offense categories. The Article 23 Legislation came into effect on March 23, 2024.

The enactment of the NSL and the Article 23 Legislation has introduced a new legal framework in Hong Kong that represents a significant departure from the legal environment that previously existed under the "one country, two system" principle. The full scope and practical application of these laws — including the definitions of prohibited conduct, the breadth of enforcement, and the extent to which they may affect business operations and the movement of personnel and information — continues to evolve and remains subject to uncertainty.

These legislative developments may adversely affect our Hong Kong operations in a number of ways, including by increasing regulatory and compliance risk for companies operating in Hong Kong, affecting the ability of our personnel to conduct business freely, and potentially restricting the flow of information, capital, and personnel between Hong Kong and other jurisdictions. In addition, the perception among foreign businesses, investors, and trading partners that Hong Kong's legal environment has become less predictable or less aligned with international norms may adversely affect business confidence, investment flows, and the broader Hong Kong economy, all of which could have a negative impact on our business and results of operations.

There can be no assurance that further changes to Hong Kong's legal or political environment will not occur, or that such changes will not adversely affect the Company's operations, financial condition, or results of operations. The Company's results of operations and financial condition may be materially influenced by the political situation in Hong Kong and by the general state of the Hong Kong economy.

**Certain Risks Relating to the Company's Business.** 

**Our operating results may fluctuate significantly from year to year. we cannot be certain that we will achieve or maintain profitability in the future.**

Our operating results historically have been difficult to predict and have at times significantly fluctuated from year to year due to a variety of factors, many of which are outside of our control.

During Fiscal 2025, the Company had revenues of US$13,265,000, operating loss of US$236,000, and loss before income taxes, equity in income of affiliates and non-controlling interests of US$140,000. In addition, we had income tax expense of US$27,000, and equity in income of affiliates of US$334,000. As a result, we had a net income of US$167,000 for Fiscal 2025 before giving effect to the effect on our results attributable to our non-controlling interests. The principal reason for the operating loss before income taxes, equity in income of affiliates and non-controlling interests for Fiscal 2025 was decrease in revenue from trading. After giving effect to the net income attributable to non-controlling interest, other comprehensive income / (loss) and comprehensive loss attributable to non-controlling interest, we had comprehensive income attributable to the Company of US$203,000 for Fiscal 2025.

During Fiscal 2024, the Company had revenues of US$15,383,000, operating income of US$386,000, and income before income taxes, equity in income of affiliates and non-controlling interests of US$519,000. In addition, we had income tax expense of US$72,000, and equity in income of affiliates of US$398,000. As a result, we had a net income of US$845,000 for Fiscal 2024 before giving effect to the effect on our results attributable to our non-controlling interests. The principal reason for the operating income before income taxes, equity in income of affiliates and non-controlling interests for Fiscal 2024 was primarily an increase in the gross profit margin of our trading, and engineering-related operations. After giving effect to the net loss attributable to non-controlling interest, other comprehensive income / (loss) and comprehensive loss attributable to non-controlling interest, we had comprehensive income attributable to the Company of US$715,000 for Fiscal 2024.

During Fiscal 2023, the Company had revenues of US$17,940,000, operating loss of US$249,000, and loss before income taxes, equity in income of affiliates and non-controlling interests of US$232,000. In addition, we had income tax expense of US$45,000, and equity in income of affiliates of US$1,927,000. As a result, we had a net income of US$1,650,000 for Fiscal 2023 before giving effect to the effect on our results attributable to our non-controlling interests. The principal reason for the operating losses before income taxes, equity in income of affiliates and non-controlling interests for Fiscal 2023 was primarily a decrease in the gross profit margin of our engineering-related operations. After giving effect to the net loss attributable to non-controlling interest, other comprehensive income / (loss) and comprehensive loss attributable to non-controlling interest, we had comprehensive income attributable to the Company of US$1,836,000 for Fiscal 2023.

As a result of these factors, comparing our operating results on a period-to-period basis may not be meaningful, and you should not rely on our past results as an indication of our future performance. Our operating expenses do not always vary directly with revenue and may be difficult to adjust in the short term. As a result, if revenue for a particular year or quarter is below our expectations, we may not be able to proportionately reduce operating expenses for that period, and therefore such a revenue shortfall would have a disproportionate effect on our operating results for that period.

**The ongoing Russia-Ukraine conflict and related geopolitical tensions may adversely affect the business operations of our suppliers and customers and the terms of our business relationships with them.**

The conflict between Russia and Ukraine, which began in February 2022 and remains ongoing, has caused significant and sustained disruptions to global supply chains, energy markets, and macroeconomic conditions. The resulting geopolitical tensions, economic sanctions, and elevated energy costs — particularly in Europe — have contributed to inflationary pressures, reduced business confidence, and constrained economic activity across multiple markets in which our customers and suppliers operate.

A number of our suppliers and customers are headquartered in Europe, and the continued effects of the Russia-Ukraine conflict on European economies may adversely affect their business operations and financial condition. As a result, these customers may take longer to make purchasing decisions with respect to our products, seek more favorable commercial and financial terms in their dealings with us, or postpone or cancel new projects and purchase orders. Any of these outcomes could adversely affect our revenues, profit margins, and results of operations.

The conflict has also caused, and continues to intensify, significant geopolitical tensions globally. The economic sanctions imposed in connection with the conflict are expected to continue to affect the economic conditions of the countries and markets targeted, and may have unforeseen secondary effects on global energy prices, commodity markets, logistics costs, and supply chains that could adversely affect our business operations. An escalation of the conflict or a significant worsening of its economic consequences could further amplify these risks.

We cannot predict the duration, resolution, or future trajectory of the Russia-Ukraine conflict or the extent to which its continued effects may materially and adversely affect our business, financial condition, and results of operations.

**Natural disasters, health epidemics, and other catastrophic events may materially and adversely affect our business and results of operations.**

Our business operations may be materially and adversely affected by natural disasters, extreme weather events, public health crises, or other catastrophic events beyond our control. Such events may disrupt our operations, those of our customers, suppliers, and business partners, and may affect regional or global economic conditions in ways that reduce demand for our products and services.

In particular, outbreaks of infectious disease or other public health emergencies — whether in mainland China, Hong Kong, Europe, or elsewhere — could result in governmental actions such as travel restrictions, quarantine measures, or business closures that disrupt our operations and supply chain, reduce customer demand, and adversely affect our financial condition and results of operations. The outbreak of COVID-19 demonstrated the significant operational, financial, and macroeconomic disruptions that a global pandemic can cause, including supply chain dislocations, reduced customer spending, and volatility in global financial markets. While the immediate operational disruptions caused by COVID-19 have largely subsided, the broader macroeconomic effects of the pandemic — including shifts in global supply chains, inflationary pressures, and changes in customer purchasing behavior — continue to affect the markets in which we operate.

We cannot predict the occurrence, duration, or severity of any future natural disaster, epidemic, or other catastrophic event, or the extent to which such events may materially and adversely affect our business, financial condition, results of operations, or the market price of our securities. Our ability to mitigate the adverse effects of such events may be limited by the availability of insurance or other protective measures, and any losses resulting from such events may not be fully covered by insurance.

**The Company's efforts to streamline its operations and increase revenues may not result in a return to profitability.**

The Company has implemented a number of measures to streamline its business activities in order to stem the decline in its revenues. Specifically, the Company has reduced the number of its employees, consolidated its offices, and ceased the active business operations of certain subsidiaries in mainland China due to their declining profitability. The Company has also been investing in the development and commercialization of its BWTS products and ballast water port solution systems as part of its strategy to diversify and grow its revenue base.

There can be no assurance that the Company's continued efforts to streamline its operations, grow its BWTS business, and promote its products will result in an increase in revenues or a return to profitability. If these efforts are unsuccessful, the Company's financial condition, results of operations, and cash flows could be materially and adversely affected.

**The market for retrofit installation of ballast water treatment systems has matured, and declining retrofit demand may adversely affect the Company's revenues and results of operations.**

The market for retrofit installation of ballast water treatment systems on existing vessels is maturing as a growing number of ship operators complete compliance with the IMO D-2 standard requirements. As a result, demand for BWTS retrofit products may decline over time. While the Company expects to offset this trend through growth in BWTS sales to the shipbuilding sector and through its port ballast water treatment solutions business, there is no assurance that such growth will be sufficient to compensate for any reduction in retrofit demand, and the Company's revenues and results of operations could be adversely affected.

**Increases in manufacturing and operating costs and/or the ability to achieve the savings anticipated from our structural cost improvement initiative may affect operating results.**

Our costs are subject to fluctuations, particularly due to changes in commodity prices, the price of raw materials, cost of energy and related utilities and cost of labor. The achievement of our financial objectives is reliant on our ability to manage these fluctuations through cost savings or recovery actions and efficiency initiatives.

We may pursue a number of structural cost improvement initiatives from time to time, but these efforts may not improve our financial performance or produce the full efficiencies and benefits we expect due to delays or other factors affecting our execution of these initiatives.

**We may be subject to a variety of litigation and similar proceedings in the course of our business that could adversely affect our financial statements.**

We may be subject to various litigations and similar proceedings incidental to our business that arise in the ordinary course of our business, including claims for damages arising out of the use of our products and claims relating to intellectual property matters, employment matters, tax matters, commercial disputes, environmental matters and personal injury. These lawsuits may include claims for compensatory damages, punitive and consequential damages and/or injunctive relief. The defense of these lawsuits may divert management's attention, we may incur significant expenses in defending these lawsuits and we may be required to pay damage awards or settlements or become subject to equitable remedies that could adversely affect our consolidated financial statements. Moreover, any insurance or indemnification rights that we have may be insufficient or unavailable to protect us against such losses and expenses. In addition, developments in legal proceedings in any given period may require us to revise our expectations regarding the outcome of certain matters or adjust the loss contingency estimate that is recorded in our consolidated financial statements, which could adversely affect our results of operations or cash flows in any particular period. We cannot assure that our liabilities in connection with litigation and similar proceedings will not exceed estimates or adversely affect our consolidated financial statements or reputation.

**Our business depends significantly on the strength of our product brands and corporate reputation; our failure to develop, maintain and enhance our product brands and corporate reputation may materially and adversely affect the level of market recognition of, and trust in, our products.**

In China's fragmented, developing and increasingly competitive consumer market, product brands and corporate reputation have become critical to the success of our new products and the continued popularity of our existing products. Our promotional activities may prove to be expensive and may fail to either effectively promote our product brands or generate additional sales.

In addition, our product brands, corporate reputation and product sales could be harmed if, for example:

· our advertisements, or the advertisements of the owners of the third-party brands that we market or those of our distributors, are deemed to be misleading or inaccurate;

· our products fail to meet customer expectations;

· we provide poor or ineffective customer service;

· our products contain defects or otherwise fail; or

· consumers confuse our products with inferior or counterfeit products.

**We have made and may make further acquisitions without your approval.**

Although we endeavor to evaluate the risks inherent in any particular acquisition, there can be no assurance that we will properly or accurately ascertain all such risks. We will have virtually unrestricted flexibility in identifying and selecting prospective acquisition candidates and in deciding if they should be acquired for cash, equity or debt, and in what combination of cash, equity and/or debt.

We have taken equity positions in related businesses. We will not seek stockholder approval for any additional acquisitions unless required by applicable law and regulations. Our stockholders may not have an opportunity to review financial and other information on acquisition candidates prior to consummation of any acquisitions under almost all circumstances.

Investors will be relying upon our management, upon whose judgment the investor must depend, with only limited information concerning management's specific intentions.

There can be no assurance that the Company will locate and successfully complete any such additional acquisitions, or any acquisition will perform as anticipated, will not result in significant unexpected liabilities or will ever contribute significant revenues or profits to the Company or that the Company will not lose its entire investment in any acquisition.

Risks related to our existing and future joint ventures, acquisitions and investments also include, as applicable:

· our ability to enter into, exit or acquire additional interests in our joint ventures or other acquisitions or investments may be restricted by or subject to various approvals under PRC law or may not otherwise be possible, may result in a possible dilutive issuance of our securities or may require us to secure financing to fund those activities;

· we may disagree with our joint venture partner(s) or other investors on how the venture or business investment should be managed and/or operated;

· to the degree we wish to do so, we may be unable to integrate and retain acquired employees or management personnel; incorporate acquired products, or capabilities into our business; integrate and support pre-existing manufacturing or distribution arrangements; consolidate duplicate facilities and functions; or combine aspects of our accounting processes, order processing and support functions; and

· the joint venture or investment could suffer losses and we could lose our total investment, which would have a negative effect on our operating results.

Any of these events could distract our management's attention and result in our not obtaining the anticipated benefits of our joint ventures, acquisitions or investments and, in turn, negatively affect the performance of such joint ventures, acquisitions and investments and their respective contributions to our results of operations.

**Dependence upon management.**

The Company is dependent upon the services of its executive officers, in particular Mr. T.C. Leung, the Chairman of the Company's Board of Directors, and Mr. David YL Leung, the Chief Executive Officer. The business of the Company could be adversely affected by the loss of services of, or a material reduction in the amount of time devoted to the Company by its executive officers. The Company does not maintain "Key Man" life insurances on the lives of any of its officers and directors. See – Item 6. "Directors, Senior Management and Employees."

**We have limited general business insurance coverage and we may be subject to losses that might not be covered by our existing insurance policies, which may result in our incurring substantial costs and the diversion of resources.**

We maintain various insurance policies to safeguard against risks and unexpected events. We have purchased product transportation insurance covering risk of product loss during transportation, property insurance for our warehouse covering the risk of product loss in the warehouse, and third party liability insurance for certain contracts. We also provide social security insurance, including work-related injury insurance, and medical insurance for our employees. However, we do not maintain business liability, interruption or litigation insurance, nor do we maintain key-man life insurance. We cannot assure you that our insurance coverage is sufficient to prevent us from any loss or that we will be able to successfully claim our losses under our current insurance policy on a timely basis, or at all. If we incur any loss that is not covered by our insurance policies, or the compensated amount is significantly less than our actual loss, our business, financial condition and results of operations could be materially and adversely affected.

**Our sale of products could subject us to product liability claims, potential safety-related regulatory actions or product recalls. These events could damage our brand and reputation and the marketability of the products that we sell, divert our management's attention and result in lower net revenues and increased costs.**

The manufacture and sale of products, such as BWTS, could expose us to product liability claims for personal injuries related liability claims. Also, if our products are deemed by the PRC authorities to fail to conform to product quality or personal safety requirements in China, we could be subject to PRC regulatory action. Violation of PRC product quality and safety requirements by products sold by us may subject us to confiscation of the products, imposition of penalties or an order to cease sales of the violating products or to cease operations pending rectification. If the offense is determined to be serious, our business license could be suspended and subject to criminal liabilities. Any product liability claim or governmental regulatory action could be costly and time-consuming to defend. If successful, product liability claims may require us to pay substantial damages. Also, a material design, manufacturing or quality failure in the products sold by us, other safety issues or heightened regulatory scrutiny could each warrant a product recall by us and result in increased product liability claims. Furthermore, customers may not use the products sold by us in accordance with our product usage instructions, possibly resulting in customer injury. All of these events could materially harm our brand and reputation and marketability of our products, divert our management's attention and result in lower net revenues and increased costs.

**We face significant competition from other distributors and manufacturers, which may adversely affect our business, revenue, and profit margins.**

We operate in a competitive market and face increasing competition from other distributors of substantially similar products, as well as from the manufacturers of those products themselves, both foreign and Chinese. Our principal competitors include foreign manufacturers and other distributors of their products based in Hong Kong and mainland China. As manufacturers increasingly seek to access the Chinese market directly — bypassing distributors such as ourselves — the competitive landscape has become more challenging.

Competitive pressures may cause customers to demand price reductions, which could compress our profit margins and adversely affect our revenue and results of operations. Additionally, a number of our existing suppliers have been selling their products into China directly and through other distributors, effectively competing with us for the same end customers. Our trading revenue decreased by approximately 23% during Fiscal 2025, and such declines may in part reflect competitive dynamics in our core markets. There can be no assurance that we will be able to maintain our competitive position, preserve existing customer relationships, or continue to compete effectively against current or new market entrants.

Increased competition could result in reduced sales volumes, loss of key customers or supplier relationships, downward pressure on pricing, and a material adverse effect on our business, financial condition, and results of operations.

**Dependence on vendors; lack of long term arrangements; loss of vendors**.

The Company distributes supplies manufactured by a number of vendors. Thermo Fisher Scientific Group ("Thermo"), Stanford Research Systems, Inc. ("Stanford"), Hach Company ("Hach"), and Hioki E.E. Corp. ("Hioki") are among the Company's largest suppliers in 2025, pursuant to short term arrangements. Although alternative sources of supply exist, there can be no assurance that the termination of the Company's relationship with any of the above or other vendors would not have an adverse effect on the Company's operations due to the Company's dependence on these vendors. A substantial number of the Company's suppliers have been selling their products into China directly and through other distributors. During Fiscal 2023, our sales revenue from trading activities increased by approximately 30%. During Fiscal 2024, our sales revenue from trading activities decreased by approximately 21%. During Fiscal 2025, our sales revenue from trading activities decreased by approximately 23%. A loss of a substantial vendor or substantial number of our other vendors and/or our competing with them would have a material adverse effect on our revenues from trading activities.

**The loss of any of our key customers could reduce our revenues and our profitability.**

For the year ended December 31, 2025, sales to our three largest customers amounted in the aggregate to approximately 35% of our total revenue. For the year ended December 31, 2024, sales to our three largest customers amounted in the aggregate to approximately 31% of our total revenue. For the year ended December 31, 2023, sales to our three largest customers amounted in the aggregate to approximately 31% of our total revenue. There can be no assurance that we will maintain or improve the relationships with these customers, or that we will be able to continue to supply these customers at current levels or at all. Any failure to pay by these customers could have a material negative effect on our company's business. In addition, having a relatively small number of customers may cause our half yearly or annual results to be inconsistent, depending upon when these customers pay for outstanding invoices.

In the years ended December 31, 2023, 2024, and 2025 we had 2, 1, and 3 customers that accounted for 10% or more of our revenues, respectively.

---

Our failure to maintain long-term relationships with any of these major customers would lead to the loss of our sales to such major customer, which would have an adverse effect on our business, financial condition and results of operations.

**We and our distributors are subject to various laws regulating our advertising and any violation of these laws by us or our distributors could result in fines, penalties and legal liabilities, harm our product brands and disrupt our business.**

We advertise and market our products. Our distributors often advertise our products they distribute. PRC advertising laws and regulations require advertisers and advertising operators, such as us and our distributors, to ensure the contents of the advertisement they prepare, publish or broadcast are fair and accurate, are not misleading and are in full compliance with applicable laws, through independent review and verification before displaying the advertisement through print media, radio or Internet portals. PRC unfair competition law also prohibits us and our distributors from displaying misleading, false or inaccurate information with respect to quality, function, use, or other features of products, through advertising. Violation of these laws or regulations may result in penalties, including fines, confiscation of advertising income, orders to cease dissemination of the advertising, orders to publish an advertisement icorrecting the misleading information and criminal liabilities. In circumstances involving serious violations, the PRC government may suspend or revoke a violator's business license. Moreover, government actions and civil claims may be filed against us for misleading or inaccurate advertising, fraud, defamation, subversion, negligence, copyright or trademark infringement or other violations due to the nature and content of our advertising produced by us or our distributors.

**Risks Related To the Company Itself.**

**Risks associated with the Holding Foreign Companies Accountable Act.**

The Holding Foreign Companies Accountable Act (the "HFCAA") and related regulations impose requirements on foreign private issuers whose auditors are not subject to satisfactory inspection by the PCAOB. Under the HFCAA, if the PCAOB is unable to inspect a company's registered public accounting firm for two consecutive years, that company's securities may be prohibited from trading on U.S. national securities exchanges and in the over-the-counter market.

On December 16, 2021, the PCAOB issued a determination that it was unable to inspect or investigate completely registered public accounting firms headquartered in mainland China or Hong Kong. Following that determination, the Company was identified as a "Commission-Identified Issuer" under the HFCAA on June 14, 2022. On December 15, 2022, following the execution of a Statement of Protocol between the PCAOB and the relevant authorities of the People's Republic of China, the PCAOB vacated its previous determinations and confirmed that it had secured complete access to inspect and investigate registered public accounting firms in mainland China and Hong Kong.

In January 2023, the Company appointed J&S Associate PLT, a Malaysia-based registered public accounting firm, as its independent auditor. J&S Associate PLT is registered with the PCAOB and is subject to PCAOB inspection, and the Company therefore believes it is not currently at risk of being identified as a Commission-Identified Issuer under the HFCAA.

As of the date of this Annual Report, the PCAOB has not issued any new determination with respect to its ability to inspect registered public accounting firms in mainland China or Hong Kong. However, the regulatory and legislative environment surrounding the HFCAA continues to evolve. Congressional discussions regarding the implementation and potential tightening of HFCAA requirements remain ongoing, and there can be no assurance that the PCAOB will not issue new determinations in the future or that legislative or regulatory changes will not impose additional requirements on foreign private issuers. Any such new determination or legislative development could adversely affect the trading of our securities on U.S. national securities exchanges.

We will monitor the PCAOB's determinations and any legislative or regulatory developments closely. If the PCAOB issues a new adverse determination with respect to registered public accounting firms in mainland China, Hong Kong, or Malaysia, or if the HFCAA is amended in a manner that subjects the Company to additional requirements, there can be no assurance that our securities would not be subject to trading prohibitions or other adverse consequences. Any such outcome could have a material adverse effect on the market price of our securities and our ability to raise capital in the U.S. markets.

**Control by T.C. Leung and David YL Leung; potential conflict of interests.**

T.C. Leung, the Company's Chairman of the Board, is the father of David YL Leung, the Chief Executive Officer of the Company. Therefore, as a practical matter, T.C. Leung and David YL Leung are able to nominate and cause the election of all the members of the Company's Board of Directors, control the appointment of its officers and the day-to-day affairs and management of the Company. As a consequence, T.C. Leung and David YL Leung can have the Company managed in a manner that would be in their own interests and not in the interests of the other shareholders of the Company. See – Item 6. "Directors, Senior Management and Employees" and Item 7. "Major Shareholders and Related Party Transactions."

**The Company does not control certain joint ventures or associated companies in which it holds interests or invests, which could limit Company's ability to identify and manage risks.**

The Company holds interests and has invested, and may continue to hold interests and invest, in joint ventures or associated companies in which it has a non-controlling interest; for example, Zhejiang Tianlan Environmental Protection Technology Co., Ltd. In these cases, Company has limited influence over, and limited or no control of, the governance, performance and cost of operations of such entities. Some of these entities may represent significant investments and potentially also use the Company's brand. These entities that Company does not control may make business, financial or investment decisions contrary to Company's interests or may make decisions different from those that Company itself may have made. Additionally, Company's partners or members of a joint venture or associated company may not be able to meet their financial or other obligations, which could expose Company to additional financial or other obligations, as well as having a material adverse effect on the value of its investments in those entities or potentially subjecting Company to additional claims.

**The Company's inability to secure and maintain intellectual property rights for products, whilst maintaining overall competitiveness, could have a material adverse effect on its results.**

The Company is dependent on its ability to obtain and maintain trademarks, patents, licenses and other intellectual property (IP) rights covering its products and its design and manufacturing processes. The IP portfolio is the result of an extensive patenting process that could be influenced by a number of factors, including innovation. The value of the IP portfolio is dependent on the successful promotion and market acceptance of standards developed or co-developed by Company.

**Failure to deal effectively with fraudulent or illegal activities by our employees, business partners or service providers would harm our business.**

Illegal, fraudulent, corrupt or collusive activities or misconduct, whether actual or perceived, by our employees, representatives, agents, business partners or service providers could subject us to liability or negative publicity, which could severely damage our brand and reputation. We have implemented and continue to improve internal controls and policies with regard to the review and approval of merchant accounts, interactions with business partners and government officials, account management, sales activities, data security and other relevant matters. However, there can be no assurance that our controls and policies will prevent fraud, corrupt or illegal activity or misconduct by our employees, representatives, agents, business partners or service providers or that similar incidents will not occur in the future. Alleged or actual failure to comply or ensure our employees, representatives, agents, business partners and service providers to comply with these requirements could subject us to regulatory investigations and liabilities, which would materially and adversely affect our business operations, customer relationships, reputation and the trading prices of our shares.

**Security breaches and attacks against our systems and network, and any potentially resulting breach or failure to otherwise protect personal, confidential and proprietary information, could damage our reputation and negatively impact our business, as well as materially and adversely affect our financial condition and results of operations.**

Our cybersecurity measures may not detect, prevent or control all attempts to compromise our systems or risks to our systems, including distributed denial-of-service attacks, viruses, Trojan horses, malicious software, break-ins, phishing attacks, third-party manipulation, security breaches, employee misconduct or negligence or other attacks, risks, data leakage and similar disruptions that may jeopardize the security of data stored in and transmitted by our systems or that we otherwise maintain. Moreover, if we fail to implement adequate encryption of data transmitted through the networks of the telecommunications and Internet operators we rely upon, there is a risk that telecommunications and Internet operators or their business partners may misappropriate our data. Breaches or failures of our cybersecurity measures could result in unauthorized access to our systems, misappropriation of information or data, deletion or modification of user information, or denial-of-service or other interruptions to our business operations. If the security of domain names is compromised, we will be unable to use the domain names in our business operations.

We may not have the resources or technical sophistication to anticipate or prevent rapidly evolving cyber-attacks. As techniques used to obtain unauthorized access to or sabotage systems change frequently and may not be known until launched against us, there can be no assurance that we will be able to anticipate, or implement adequate measures to protect against, these attacks. We could also be subject to an attack, breach or leakage, which we do not discover at the time or the consequences of which are not apparent until a later point in time. We do not carry any cybersecurity insurance and actual or anticipated attacks and risks may cause us to incur significantly higher costs, including costs to deploy additional personnel and network protection technologies, train employees, and engage third-party experts and consultants.

Cyber-attacks and security breaches could subject us to negative publicity, regulatory investigations and significant legal and financial liability, harm our reputation and result in substantial revenue loss from lost sales and customer dissatisfaction, materially decrease our revenue and net income, and negatively affect the trading prices of our shares.

**The costs of complying with evolving regulatory requirements could negatively impact the Company's financial results. Actual or alleged violations of environmental laws or permit requirements could result in restrictions or prohibitions on plant operations, substantial civil or criminal sanctions, as well as the assessment of strict liability and/or joint and several liability.**

The Company may be subject to local laws, regulations, rules and ordinances relating to pollution, protection of the environment, greenhouse gas emissions, and the generation, storage, handling, transportation, treatment, disposal and remediation of hazardous substances and waste materials. In addition, the Company may have costs related to environmental remediation and restoration obligations associated with past and current sites as well as related to the Company's past or current waste disposal practices or other hazardous materials handling. Although management will estimate and accrue liabilities for these obligations, it is reasonably possible that the Company's ultimate cost with respect to these matters could be significantly higher, which could negatively impact the Company's financial condition and results of operations. Costs and capital expenditures relating to environmental, health or safety matters are subject to evolving regulatory requirements and depend on the timing of the promulgation and enforcement of specific standards which impose the requirements. Moreover, changes in environmental regulations could inhibit or interrupt the Company's operations, or require modifications to its facilities. Accordingly, environmental, health or safety regulatory matters could result in significant unanticipated costs or liabilities.

**Increased concerns regarding the safe use of chemicals and plastics in commerce and their potential impact on the environment as well as perceived impacts of plant biotechnology on health and the environment have resulted in more restrictive regulations and could lead to new regulations.**

Concerns regarding the safe use of chemicals and plastics in commerce and their potential impact on health and the environment and the perceived impacts of plant biotechnology on health and the environment reflect a growing trend in societal demands for increasing levels of product safety and environmental protection. These concerns could manifest themselves in stockholder proposals, preferred purchasing, delays or failures in obtaining or retaining regulatory approvals, delayed product launches, lack of market acceptance and continued pressure for more stringent regulatory intervention and litigation. These concerns could also influence public perceptions, the viability or continued sales of certain of the Company's products, the Company's reputation and the cost to comply with regulations. In addition, terrorist attacks and natural disasters have increased concerns about the security and safety of chemical production and distribution. These concerns could have a negative impact on the Company's results of operations.

**Far East has made payment for a property in Beijing, China but has not obtained title to such property from the PRC authority, which may result in legal proceedings and associated costs, expenses, and liabilities.**

Far East made payment for the purchase of a property located in Beijing, China and received rental income on such property pursuant to a series of lease agreements. The latest lease agreement relating to such property terminated in December 2025 and no rental income has been received from the property since that date. Notwithstanding its payment of the purchase price, Far East has not successfully obtained a Certificate of Real Estate Ownership or title to such property from the PRC authority. The property's book value as of December 31, 2025 was approximately US$71,000. Far East has made efforts to request the developer of the property to assist with obtaining the title, but those efforts have not succeeded. Far East is continuing to investigate available means by which to obtain title to the property but has not formulated a specific plan as of the date of this Annual Report.

If the property is to be disposed of, it is likely that Far East's title to the property will be challenged, in which case the Company and/or Far East will need to incur additional costs and expenses to confirm and defend its title to the property and the rental income previously collected. There is no assurance that Far East will succeed in its efforts to obtain title to the property. Far East's failure to obtain title could have a material adverse effect on the Company's financial position, results of operations, and cash flows.

**Certain legal consequences of incorporation in the British Virgin Islands; rights of shareholders not as extensive as in U.S. corporations.**

Principles of BVI corporate law relating to such matters as the validity of the Company procedures, the fiduciary duties of management and the rights of the Company's shareholders may differ from those that would apply if the Company were incorporated in a jurisdiction within the United States.

The rights of shareholders under BVI law are not as extensive as the rights of shareholders under legislation or judicial precedent in many United States jurisdictions. Under United States law, majority and controlling shareholders generally have certain "fiduciary" responsibilities to the minority shareholders. United States shareholder action must be taken in good faith and actions by controlling shareholders in a United States jurisdiction and executive compensation which are obviously unreasonable may be declared null and void.

The BVI law protecting the interests of the minority shareholders is not as protective in all circumstances as the law protecting minority shareholders in United States jurisdictions. The shareholders of the Company may have more difficulty in protecting their interests in the face of actions by the Company's Board of Directors, and may have more limited rights, than they might have as shareholders of a company incorporated in many United States jurisdictions.

**Anti-takeover provisions.**

The Company has 5,000,000 shares of "blank check preferred stock" authorized. The "blank check preferred stock" is intended to strengthen the Company's ability to resist an unsolicited takeover bid and may be deemed to have an anti-takeover effect. The Board of Directors has the right to fix the rights, terms and preferences at the time of issue of "blank check preferred stock" without further action by our shareholders.

**Uncertainty of enforcing United States judgments.**

There is some uncertainty whether BVI courts would enforce judgments of the courts of the United States and of other foreign jurisdictions, or enforce actions brought in the BVI which are based upon the securities laws of the United States. A final monetary judgment obtained in the United States will be treated as a cause of action in itself by the BVI courts so that no retrial of the issues would be necessary, provided that material preconditions are met and the proceedings pursuant to which judgment was obtained were not contrary to the rules of natural justice.

All of the Company's directors and executive officers reside outside of the United States, service of process upon the Company and such persons may be difficult to effect in the United States upon all such directors and officers.

All of the Company's assets are and will be located outside of the United States, in Hong Kong and the PRC, and any judgment obtained in the United States may not be enforced in those jurisdictions. Hong Kong courts will not directly enforce against the Company or such persons judgments obtained in the United States. There is also substantial doubt as to the enforceability in the PRC of actions to enforce judgments of the United States' courts arising out of or based on the ownership of the securities, including judgments arising out of or based on the civil liability provisions of United States federal or state securities laws or otherwise. See — "Certain Legal Consequences of Incorporation in the British Virgin Islands; Rights of Shareholders Not As Extensive As In U.S. Corporations."

**Being a Foreign Private Issuer exempts us from certain SEC and Nasdaq Stock Market requirements.**

We are a foreign private issuer within the meaning of rules promulgated under the Securities Exchange Act of 1934 (the "Exchange Act"). As such, with certain limitations, we are exempt from certain provisions applicable to United States public companies including: (1) the rules under the Exchange Act requiring the filing with the Commission of quarterly reports on Form 10-Q or current reports on Form 8-K; (2) the sections of the Exchange Act regulating the solicitation of proxies, consents or authorizations in respect of a security registered under the Exchange Act; (3) the provisions of Regulation FD aimed at preventing issuers from making selective disclosures of material information; and (4) the sections of the Exchange Act requiring insiders to file public reports of their stock ownership and trading activities and establishing insider liability for profits realized from any "short-swing" trading transaction (i.e., a purchase and sale, or sale and purchase, of the issuer's equity securities within less than six months). Because of these exemptions, investors are not afforded the same protections or information generally available to investors holding shares in public companies organized in the United States.

**Risks related to our listing on the Nasdaq Capital Market**

Our ordinary shares are currently listed on the Nasdaq Capital Market. In order to maintain this listing, we must satisfy minimum financial and other continued listing requirements and standards, including those regarding minimum bid price. If we fail to satisfy the continued listing requirements of the Nasdaq Capital Market, such as the minimum bid price requirement, Nasdaq may take steps to delist our ordinary shares.

Nasdaq's continued listing standards require, among other things, that our ordinary shares maintain a minimum bid price of at least $1.00 per share. If our ordinary shares fail to meet this minimum bid price requirement for 30 consecutive business days, Nasdaq will notify us of our non-compliance. Upon receipt of such a notice, we would generally have an initial period of 180 calendar days to regain compliance, which may be extended under certain circumstances. During any such compliance period, we may be required to effect a reverse stock split or take other measures to increase our share price above the minimum threshold.

A delisting of our ordinary shares from the Nasdaq Capital Market could adversely affect our ability to attract new investors, decrease the liquidity of our outstanding common shares, reduce our flexibility to raise additional capital, reduce the price at which our ordinary shares trade, and increase the transaction costs inherent in trading such shares with overall negative effects for our shareholders. In addition, delisting could harm our business, prospects, financial condition, and results of operations. We can provide no assurances that our ordinary shares will continue to meet Nasdaq's listing requirements or that we will be able to regain compliance in the event we receive a deficiency notice in the future.

**We are also required to meet certain, but not all, corporate governance criteria applicable to Nasdaq listed issuers.**

Although, in the past, we have been able to satisfy corporate governance criteria applicable to Nasdaq listed issuers, those criteria are difficult to comply with and include, among other things: (a) a heightened degree of independence of members of the board of directors with independent directors to, among other things: hold regular meetings among themselves only; (b) establishment of a code of conduct addressing compliance with laws; and (c) a limit on payments to independent directors and their family members (other than for services on the board of directors).

These corporate governance requirements and a strict definition of "independent director" make it more difficult to find independent directors for our Board of Directors. There is intense competition for qualified independent directors, including those persons with accounting experience and financial statement acumen to serve on audit committees. We believe that continued compliance with the corporate governance requirements applicable to Nasdaq listed issuers may be difficult and increase our costs and expenses as the costs of finding and compensating independent directors escalate and the costs of administering their new powers and responsibilities is an added financial burden. If we are unable to attract and keep a sufficient number of independent directors willing to take on the responsibilities imposed by such rules on what we believe to be commercially reasonable terms, our securities may be delisted from NASDAQ. See— "Being a 'Controlled Company' Exempts Us from Certain Other Corporate Governance Criteria Applicable to NASDAQ Listed Issuers."

**Being a "Controlled Company" exempts us from certain other corporate governance criteria applicable to Nasdaq listed issuers.**

As a result of T.C. Leung, the Company's Chairman of the Board, beneficially owning the majority voting power of our ordinary shares, we are a "controlled company" as that term is defined in rules and regulations applicable to NASDAQ listed issuers. As a "controlled company," we are not required to comply with certain NASDAQ corporate governance criteria including, among other things, the requirements that the majority of our Board be independent directors, and their having the authority to approve director nominations and executive officer compensation.

**We are not subject to various corporate governance measures, which may result in shareholders having limited protections.**

The Sarbanes-Oxley Act of 2002 ("SOX"), has resulted in the adoption of various corporate governance measures by securities exchanges and NASDAQ designed to promote the integrity of the corporate management and the securities markets. Being a "controlled company," we are exempt from many, but not all, of those requirements. Furthermore, the absence of such practices with respect to our Company may leave our shareholders without protections against interested director transactions, conflicts of interest and similar matters.

**We may be exposed to potential risks relating to our internal controls over financial reporting.**

Pursuant to Section 404 of SOX, the SEC adopted rules requiring public companies to include a report of management on the Company's internal controls over financial reporting in their Annual Reports, including Form 20-F.

We expend significant resources in developing and maintaining the necessary documentation and testing procedures required by SOX, there is a risk that we will not maintain compliance with all of these requirements.

In the event we identify significant deficiencies or material weaknesses in our internal controls that we cannot remediate in a timely manner our ability to obtain equity or debt financing could suffer and the market price of our shares could decline.

**The market price of our ordinary shares may be volatile or may decline regardless of our operating performance, and you may not be able to resell your shares at or above the price you paid.**

The trading price for our ordinary shares may be volatile and could fluctuate widely in response to a variety of factors, many of which are beyond our control. This may happen because of broad market and industry factors, including the performance and fluctuation of the market prices of other companies with business operations located in China that have listed their securities in the United States. The trading performances of these other companies' securities may affect the attitudes of investors toward similar companies listed in the United States, which consequently may impact the trading performance of our ordinary shares, regardless of our actual operating performance. In addition, any negative news or perceptions about inadequate corporate governance practices or fraudulent accounting, corporate structure or matters of these other companies may also negatively affect the attitudes of investors towards companies with business operations in China in general, including us, regardless of our conduct. The market price of our ordinary shares may fluctuate significantly in response to numerous factors, many of which are beyond our control, including:

· changes in the general environment and the outlook of the segments in which we operate;

· regulatory developments in the segments in which we operate;

· actual or anticipated fluctuations in our half yearly or annual results of operations;

· changes in financial estimates by securities research analysts;

· negative market studies or reports;

· changes in performance and valuation of our peer or comparable companies;

· announcements by us or our competitors of new services, acquisitions, strategic relationships, joint ventures or capital commitments;

· changes in pricing we or our competitors adopt;

· changes in our senior management;

· litigation and regulatory allegations or proceedings that involve us or our ecosystem participants;

· sales or anticipated sales of additional ordinary shares; and

· fluctuations in the exchange rate between the Renminbi and the U.S. Dollar.

---

In addition, the securities markets in the United States, China and elsewhere have from time to time experienced significant price and volume fluctuations that are not related to the operating performance of particular companies. These market fluctuations may also materially and adversely affect the market price of the ordinary shares.

**There are risks in purchasing low-priced securities.**

If our securities were to be suspended or delisted from Nasdaq, they could be subject to rules under the Exchange Act which impose additional sales practice requirements on broker-dealers who sell such securities to persons other than established clients and "accredited investors." For transactions covered by such rules, a broker-dealer must make a special suitability determination of the purchaser and have received the purchaser's written consent to the transaction prior to the sale. Consequently, such rules may affect the ability of broker-dealers to sell our securities and the ability to sell any of our securities in any secondary market that may develop for such securities. In the event our securities are no longer listed on Nasdaq or are not otherwise exempt from the provisions of the SEC's "penny stock" rules, such rules may also affect the ability of broker-dealers and investors to sell our securities.

**We may be considered to be a passive foreign investment company for the 2024 calendar year and may be a passive foreign investment company for future years, which would result in adverse U.S. federal income tax consequences to U.S. holders of our ordinary shares.** 

A non-U.S. corporation will be considered a passive foreign investment company ("PFIC") for U.S. federal income tax purposes, for any taxable year if either (i) at least 75% of its gross income for such taxable year is passive income or (ii) at least 50% of the value of its assets (based on an average of the quarterly values of the assets during a taxable year) is attributable to assets that produce or are held for the production of passive income. The annual PFIC determination to be made by a U.S. holder of our ordinary shares is an inherently factual determination based upon the application of complex U.S. federal income tax rules (which are subject to differing interpretations), the composition of our income and assets from time to time, and the nature of the activities performed by our officers and employees. We currently hold a substantial amount of cash and cash equivalents, and investments in PRC enterprises, and the value of our goodwill and other assets may be based in part on the market price of our ordinary shares, which has experienced significant fluctuations. Although the determination of PFIC status is subject to factual uncertainties because it depends upon the valuation of our ordinary shares, as well as our goodwill and other assets and income, and because there are uncertainties in the application of the relevant rules, we are uncertain if we would be considered to be a PFIC for 2025. In addition, as the determination of PFIC status is made on an annual basis and depends on variables over which we have limited control, there can be no assurance that we will not be a PFIC for 2026 or any future years. If we are a PFIC in any year, a U.S. holder may be subject to certain adverse United States federal income tax consequences, and is urged to consult with his, her or its tax advisor. See— *Item 10. "Taxation—United States Federal Income Taxation*."

**If we become directly subject to the recent scrutiny involving U.S.-listed Chinese companies, we may have to expend significant resources to investigate and/or defend the matter, which could harm our business operations, stock price and reputation and could result in a complete loss of your investment in us.**

U.S. listed companies that have substantial operations in China have been the subject of intense scrutiny by investors, financial commentators and regulatory agencies. Much of the scrutiny has centered on financial and accounting irregularities and mistakes, a lack of effective internal controls over financial reporting and, in many cases, allegations of fraud. As a result of the scrutiny, the publicly traded stock of many U.S. listed China-based companies that have been the subject of such scrutiny has sharply decreased in value. Many of these companies are now subject to shareholder lawsuits and/or SEC enforcement actions that are conducting internal and/or external investigations into the allegations. If we become the subject of any unwarranted scrutiny, even allegations that are not true, we may have to expend significant resources to investigate such allegations and/or defend the Company. Such investigations or allegations will be costly and time-consuming and distract our management from our business plan and could result in our reputation being harmed and our stock price could decline as a result of such allegations, regardless of the truthfulness of the allegations.

**ITEM 4. INFORMATION ON THE COMPANY**

**A. HISTORY AND DEVELOPMENT OF THE COMPANY**

The Company was organized under the laws of the BVI on September 30, 1996 for the purposes of raising capital and for acquiring all the outstanding capital stock of Euro Tech (Far East) Limited ("Far East"), a Hong Kong corporation. In March 1997, the Company acquired all the issued and outstanding capital stock of Far East and Far East became a wholly-owned subsidiary of the Company.

Yixing Pact Environmental Technology Company Limited, a Chinese company ("Yixing") and Pact Asia Pacific Limited, a BVI company ("Pact," collectively with "Yixing", "Pact-Yixing") became Far East's majority-owned subsidiaries in 2005. We acquired additional two percent (2%) and five percent (5%) equity interests in Pact and Yixing in January 2010 and July 2011, respectively, through Far East. Since then, Far East has been the holder of fifty-eight percent (58%) equity interests in Pact and Yixing respectively. In 2020, Pact-Yixing successfully developed and launched a ballast water port solution system for ship vessels and port harbors. This positions Pact-Yixing to be one of the first few companies in Asia capable of developing and selling such system for commercial use in the port and harbor sector.

Far East also owns a 19.42% equity interest in Zhejiang Tianlan Environmental Protection Technology Co. Ltd. ("Blue Sky"), founded in 2000. Blue Sky provides design and general contracting services, equipment manufacturing, installation, testing and operation management for the purification treatment of industrial waste gases (specifically as desulphurization, flue gas de-nitration, dust removal) emitted from various boilers and industrial furnaces of power plants, steelworks and chemical plants. By securing an equity stake in Blue Sky's business, we have a strategic partner to work within China's environmental protection business. With Blue Sky's technology and technical support, we believe we are able to provide services and environmental solutions not only for water and wastewater treatment but also for air pollution control for industrial clients in China.

Blue Sky's revenue decreased in Fiscal 2023 as compared to Fiscal 2022, increased in Fiscal 2024 as compared to Fiscal 2023, and decreased in Fiscal 2025 as compared to Fiscal 2024. The decrease in revenue in Fiscal 2025 was mainly due to the postponement of certain projects and a decrease in revenue from a Build-Operate-Transfer ("BOT") project. Blue Sky's net income increased in Fiscal 2023 as compared to Fiscal 2022, decreased in Fiscal 2024 as compared to Fiscal 2023, and decreased further in Fiscal 2025 as compared to Fiscal 2024. The decrease in net income in Fiscal 2025 was primarily due to a decrease in gross profit resulting from the decline in revenue, particularly revenue from a BOT project that carries a higher gross profit margin than Blue Sky's other projects. Blue Sky has listed its shares on the New Third Board in the PRC since November 17, 2015. The New Third Board in the PRC, a national over-the-counter market in the PRC regulated by the China Securities Regulatory Commission, serves as a trading platform for small and medium-sized enterprises. Any new issuance of Blue Sky's shares on the New Third Board will dilute our ownership in Blue Sky. On the other hand, the New Third Board provides us with an exit channel to sell our position in Blue Sky if the price is attractive.

In Fiscal 2025, Blue Sky made an income contribution of US$334,000 to the Company, compared to US$398,000 in Fiscal 2024 and US$1,927,000 in Fiscal 2023. The significant income contribution in Fiscal 2023 was attributed primarily to non-recurring income from the disposal of two desulfurization treatment plants in connection with a BOT project located in Shanxi, China, and is not expected to recur. The Fiscal 2025 and Fiscal 2024 income contributions were derived from operating income.

China's 14th Five-Year Plan promotes a cleaner and greener economy, with strong commitments to environmental management and protection, clean energy and emissions controls, ecological protection and security, and the development of green industries. This reflects a clear long-term commitment to sustainable economic development and China's ambition to play a meaningful global role in curbing greenhouse gas emissions. Management believes that the policy direction reflected in the 14th Five-Year Plan may benefit the Company's business as well as the business of its affiliate, Blue Sky, by increasing demand for environmental technology products and services of the type the Company and Blue Sky provide.

We previously had a 20% equity interest in Zhejiang Jia Huan Electronic Co. Ltd., a company incorporated in the PRC ("Jia Huan"), with total cost of investment US$2,486,000. On March 5, 2018, we entered into an Equity Transfer Agreement to sell this 20% equity stake of Jia Huan for a purchase price of RMB 31,312,500 to Ms. Jin Lijuan (the "Purchaser"), the wife of the holder of the remaining 80% equity stake of Jia Huan. In accordance with the terms of the relevant agreement, all approvals and registrations with the relevant governmental authorities were obtained, the closing of the transaction has been completed, and the Purchaser paid the purchase price to us in full in May 2018. As a result, we recognized a net gain of US$1,522,000 on the disposal of our equity interest in Jia Huan.

In 2019, the Company dissolved three subsidiaries — Chongqing Euro Tech Rizhi Technology Co., Ltd., Rizhi Euro Tech Instrument (Shaanxi) Co., Ltd., and Guangzhou Euro Tech Environmental Equipment Co., Ltd. — as part of its ongoing efforts to streamline its corporate structure and reduce operational complexity.

In January 2021, the Company closed the representative sales office of Shanghai Euro Tech Limited located in Beijing.

On July 2, 2021, the Company dissolved Shanghai Euro Tech Environmental Engineering Company Ltd. ("Shanghai Environmental"), a wholly-owned subsidiary organized under the laws of the PRC, in order to avoid duplication of costs and efforts with Pact-Yixing, in which the Company holds a 58% equity interest and which conducts similar business activities.

The Company also ceased the active business operations of Euro Tech Trading Services Limited ("ETTS") in 2021 and of Shenzhen Euro Tech Instruments Co., Ltd. ("SET") in 2022, and subsequently deregistered SET in 2024. Prior to the cessation of its active business operations, SET was engaged in the manufacturing of analytical and testing instruments. SET had incurred losses from its operations in the years preceding the cessation of its business, and the decision was made to wind down its active operations accordingly.

We incorporated Euro Tech Global as a wholly-owned subsidiary in 2025. Euro Tech Global holds 100% of the shares of Far East. We also incorporated Pact Singapore in 2024. Far East holds 58% of the shares of Pact Singapore.

Our principal place of business is located at Unit D, 18/F., Gee Chang Hong Centre, 65 Wong Chuk Hang Road, Hong Kong, China and the telephone number is 852-28140311. The SEC maintains an Internet site that contains reports, proxy and other information regarding issuers that file electronically with the SEC (such as the Company) and the address of that site is <u>http://www.sec.gov</u>. The Company maintains a website at http://www.euro-tech.com.

**B. BUSINESS OVERVIEW**

See – "Glossary."

· **Continuous-reading process analyzers and related products** - including process turbidimeters, pH controllers and analyzer accessories. These products are used to monitor and control drinking water quality and to ensure that water treatment procedures comply with applicable regulatory standards. See – "Glossary."

**Engineering and Manufacturing Activities**

Pact-Yixing, in which Far East holds a 58% equity interest, provides customers with engineering solutions for industrial water and wastewater treatment projects and develops ballast water treatment technology. Pact-Yixing conducts industrial water and wastewater treatment projects primarily for large multinational manufacturing facilities located in the PRC that are operated by companies headquartered in the United States, Europe, and Japan. Pact-Yixing's clients operate across a broad spectrum of industries, including semiconductor, pharmaceutical, petrochemical, automotive and auto parts, steel, food and beverage, and consumer products manufacturing.

Pact-Yixing also conducts process design projects for its clients. The mechanical and electrical engineering components of such projects are completed in-house, while manufacturing procedures are contracted to approved fabricators of components. Fabrication drawings are prepared in-house for submission to those fabricators under the supervision of Pact-Yixing's quality control engineers.

The water and wastewater treatment processes applied by Pact-Yixing encompass chemical, physical, biological, and membrane separation technologies, which are typically used in combination to treat specific industrial process feeds or effluents. On the water treatment side, Pact-Yixing designs and builds filtration equipment, ion-exchange softeners and demineralizers, reverse osmosis systems, electro-deionization systems, chemical treatment systems, and package-type mobile water treatment plants. On the wastewater treatment side, Pact-Yixing designs and builds biological treatment systems, oil coalescers, dissolved air flotation systems, lamella clarifiers, chemical reactor tanks, ultrafiltration and microfiltration systems, dewatering systems, and package-type mobile sewage treatment plants.

**Ballast Water Treatment Technology**

Pact-Yixing manufactures its own proprietary ballast water treatment system ("BWTS") for the maritime industry, targeting shipowners, shipyards, and port and harbor operators. In 2020, Pact-Yixing completed the first commercial sale of a ballast water port solution system, positioning it as one of the first companies in Asia capable of delivering a complete ballast water port solution system. Pact-Yixing promotes two principal BWTS product lines: on-board shipping applications and mobile port ballast water treatment reception facility applications.

Pact-Yixing continues to promote this technology for commercial sale to customers located in countries participating in the Belt and Road Initiative and in maritime cities across the Middle East, Southeast Asia, and Europe. The Company intends to continue identifying potential new markets and seeking distributors and partners in global territories to promote its BWTS products and engineering, procurement, and construction ("EPC") services for water treatment systems and equipment. The Company may seek additional capital through various means to fund this development. While efforts to refine and promote the BWTS may incur additional costs and expenses that affect results of operations in the near term, the Company believes that this technology will, in the long run, provide a competitive advantage and support its broader strategic objective of transitioning from a company primarily reliant on distribution and engineering activities to a technology-driven enterprise.

The Company has obtained a number of certifications and type approvals from governmental authorities and international classification societies in order to enhance the credibility and marketability of its BWTS products. Pact-Yixing has received type approvals from China Classification Society ("CCS"), the Russian Maritime Register of Shipping ("RS"), Lloyd's Register ("LR"), and Bureau Veritas ("BV"). The RS type approval covers the Company's full range of BWTS products, while the LR and BV type approvals cover the Company's partial range of BWTS products. In addition, Pact-Yixing has received an anti-explosion certificate from the China National Quality Supervision and Test Centre for Explosion Protected Electrical Products in respect of its BWTS products. The Company continues to seek additional type approvals from European and Asian classification societies to broaden the range of markets in which its BWTS products may be sold.

The development of the ballast water port solution has progressed from prototype stage to full commercial deployment. The Company received its first order for the ballast water port solution system from Shanghai Yanshan port in 2020, and has since completed seven additional commercial port BWTS projects in China, bringing its total number of completed commercial port projects to eight. The completed projects are located at Shanghai Yanshan port, Ningbo Zhoushan port, Taicang port, Lianyungang petrochemical port, Zhangjiang chemical port, a second petrochemical port in Lianyungang, Mou Ming petrochemical port, and a container port in Hainan.

The Company conducts ongoing promotional activities for such systems in China, and elsewhere, where appropriate. However, the intake of orders may be affected by, among other things, the success of the Company's marketing and sales efforts, and by the acceptance of the Company's products by customers.

**Business Strategy**

Revenues from the Company's trading activities have decreased in recent years, as a substantial number of the Company's suppliers have been selling their products directly into China and through other distributors, many of which are local Chinese companies that operate with lower overhead. In response, the Company has been shifting its emphasis from the distribution of instruments and equipment toward engineering, manufacturing, and technology activities.

For a discussion of the Company's financial performance from its principal business activities, including revenues and operating results from trading and engineering activities, see "Item 5 — Operating and Financial Review and Prospects."

**Principal Markets: Mainland China and Hong Kong**

The Company's operations are conducted, and its revenues are generated, almost entirely in mainland China and Hong Kong. Set forth below are the approximate percentage of the Company's revenue attributable to customers in mainland China and Hong Kong, respectively, for each of the fiscal years indicated:

---

| | | |
|:---|:---|:---|
| **Fiscal Year** | **Mainland China** | **Hong Kong** |
| 2023 | 40% | 55% |
| 2024 | 42% | 44% |
| 2025 | 50% | 45% |

Sales to customers situated in Macau and other markets outside mainland China and Hong Kong represented approximately 5%, 14%, and 5% of the Company's total revenues in Fiscal 2023, Fiscal 2024, and Fiscal 2025, respectively. The concentration of the Company's operations and revenues in mainland China and Hong Kong makes the Company particularly susceptible to changes in the political, legal, and economic environment of either jurisdiction.

Hong Kong.

Hong Kong is a Special Administrative Region of the PRC. On July 1, 1997, sovereignty over Hong Kong was transferred from the United Kingdom to the PRC pursuant to the Sino-British Joint Declaration on the Question of Hong Kong (the "Joint Declaration") and the Basic Law of Hong Kong (the "Basic Law"). Under the Basic Law, Hong Kong is afforded a high degree of autonomy except in matters of foreign affairs and defense, and maintains its own legislature, legal and judicial system, and full economic autonomy for a period of 50 years following the transfer of sovereignty.

In recent years, Hong Kong's legal and political environment has undergone significant change, including the enactment of the National Security Law in June 2020 and the Article 23 Legislation in March 2024. These developments have introduced material changes to Hong Kong's legal framework that may affect the environment in which the Company operates. There can be no assurance that further changes to Hong Kong's political or legal environment will not occur, or that such changes will not adversely affect the Company's financial and operating environment. See "Item 3.D — Risk Factors — PRC National Security Legislation and Political Developments in Hong Kong" for a more detailed discussion of these risks.

Revenue attributable to Hong Kong customers, expressed as a percentage of total revenues, increased by 7% in Fiscal 2023 compared to Fiscal 2022, decreased by 11% in Fiscal 2024 compared to Fiscal 2023, and increased by 1% in Fiscal 2025 compared to Fiscal 2024.

Mainland China.

Mainland China has been a socialist state since 1949, and its economy continues to operate under significant government oversight and control. In recent decades, the government has undertaken reforms to permit greater provincial and local economic autonomy and private economic activity. However, the direction of mainland China's economic policy has in recent years shifted toward greater state oversight of private enterprise and increased regulation of industries deemed strategically important. Any change in the political or economic conditions of the PRC, or in the policies of the PRC government, may substantially and adversely affect the business environment in which the Company operates and, in turn, the Company's business, financial condition, and results of operations. See "*Item 3.D — Risk Factors — Changes in the Economic and Political Policies of the PRC Government could have a material and adverse effect on our business, financial condition and results of operations*" for a more detailed discussion of these risks.

Revenue attributable to customers in mainland China, expressed as a percentage of total revenues, increased by 1% in Fiscal 2023 compared to Fiscal 2022, increased by 2% in Fiscal 2024 compared to Fiscal 2023, and increased by 8% in Fiscal 2025 compared to Fiscal 2024. See "Item 3.D — Key Information — Risk Factors."

**Our Growth Strategy** 

**Geographic focus of distribution activities**

The Company has focused its trading and distribution activities on Hong Kong, Macau, and the Guangdong province of mainland China. Given the proximity of these markets to the Company's Hong Kong headquarters, this geographic focus allows the Company to provide more responsive customer support and technical assistance while maintaining lower operational costs than would be required to support a distribution network across a wider geographic area of mainland China.

**Ballast water treatment systems**

Pact-Yixing manufactures and sells a proprietary BWTS targeting the maritime industry, including shipowners, shipyards, and port and harbor operators. The BWTS product line encompasses two principal applications: on-board shipping applications and mobile port ballast water treatment reception facility applications.

The development of the Company's BWTS dates to 2010, when Pact-Yixing began developing a non-chemical ballast water treatment solution. In 2012, Pact-Yixing successfully completed land-based testing requirements, and in 2014, Pact-Yixing passed ship-board testing and obtained certification from the China Classification Society ("CCS") in compliance with IMO convention requirements. On September 8, 2017, the IMO Ballast Water Management Convention entered into force following acceptance by 52 states representing approximately 35% of world merchant shipping tonnage. In July 2017, the IMO determined that the phase-in period for ballast water system retrofits would commence on September 8, 2019. The IMO convention stipulates that type approval for revised G8 requirements must be obtained for all BWTS installed on or after October 28, 2020, and Pact-Yixing has been in compliance with such requirements. Pact-Yixing has also received type approval certificates from Lloyd's Register, RINA and Bureau Veritas, and has been pursuing type approval certificates from additional European and Asian classification societies to expand its market coverage.

In 2018, the Company received a PRC government grant to fund the development of a ballast water port solution prototype. The prototype was completed in 2019, and the system was developed for commercial use in 2020. In 2020, Pact-Yixing completed the first commercial sale of a ballast water port solution system, positioning it as one of the first companies in Asia capable of delivering a complete ballast water port solution system. The Company has obtained 5 utility model patents and has 1 invention patent application pending in mainland China in respect of this port solution system.

The following table summarizes Pact-Yixing's BWTS sales over the past three fiscal years:

---

| | | | |
|:---|:---|:---|:---|
| Fiscal Year | BWTS for Ship Vessels | BWTS Port Solution Units | Key Markets |
| 2023 | 34 sets | 1 unit | China, Dubai, Turkey, Thailand, Singapore |
| 2024 | 45 sets | 1 unit | China, Dubai, Turkey, Singapore |
| 2025 | 30 sets | 2 units | China, Turkey and Dubai  |

---

The decrease in BWTS vessel unit sales from 45 sets in Fiscal 2024 to 30 sets in Fiscal 2025 reflects, in part, a broader industry trend toward market equilibrium for ship retrofit projects. As the compliance deadline under the IMO Ballast Water Management Convention's D-2 standard has now largely passed, the global pool of vessels requiring retrofit installation of BWTS has diminished. The Company does not expect this trend to materially affect its longer-term growth prospects, as demand for BWTS products in the shipbuilding sector and for port ballast water treatment solutions is expected to continue to grow.

The Company's BWTS products are capable of treating ballast water at rates of 50, 100, 150, 200, 300, 500, 750, 1,200, and 1,250 cubic meters per hour. The Company continues to invest in the development and promotion of its BWTS product lines and to enhance its after-sales services for BWTS customers, with the objective of maximizing the Company's value proposition in turnkey water-related treatment solutions for the maritime industry.

The Company has been actively promoting its BWTS products globally through participation in major maritime trade shows and exhibitions. In 2025, the Company participated in two maritime trade shows held in Singapore and Indonesia, respectively. The Company continues to seek additional distributors and to replace non-performing partners in maritime cities and countries in order to expand its market reach. The Company's former strategic OEM partner in Greece, which had previously distributed the Company's BWTS products on an exclusive basis to 20 countries across Europe, did not generate any sales during the partnership period. As a result, the exclusive arrangement was transitioned to a non-exclusive basis and the OEM business partnership was subsequently terminated. The Company also intends to expand its promotional efforts in Southeast Asia and Northern Europe to diversify its business and capture market growth opportunities in those regions.

The Company is actively promoting its mobile ballast water port reception and treatment solution in response to an emerging market for onshore systems capable of providing emergency and rapid treatment services. Demand for such systems is being driven by increasingly stringent local environmental regulations, particularly in regions experiencing high port congestion. As more countries establish and enforce rigorous environmental policies, port states are expected to further mandate compliance with ballast water treatment requirements, driving demand for port-based solutions across key markets. The Company is actively seeking strategic distribution and commercial partners to expand its presence in the port BWT solutions market, with a particular focus on Europe, where regulatory enforcement is among the most stringent globally.

**Industrial wastewater and Southeast Asia expansion**

The Company has incorporated Pact Environmental Technology Pte. Ltd. ("Pact Singapore") with the intention of expanding into the Southeast Asia region and the industrial wastewater market. Singapore's position as one of the world's largest shipping hubs, its strong regulatory environment, and its role as a regional business center make it a strategically important base from which to serve customers across Southeast Asia. The Company has also observed a trend of foreign companies expanding into or relocating to Southeast Asia, and believes that a presence in Singapore will provide better access to this growing market.

**Handheld ballast water checker** 

The Company has developed a handheld ballast water checker based on pulse amplitude modulation ("PAM") fluorescence technology, which is designed as a screening tool for shipowners, compliance officers, shipbuilders, and BWTS providers. The Company has obtained patent approval for this instrument in mainland China and has carried out testing at the land-based test facility of a Chinese National Engineering Laboratory for Ballast Water Testing, obtaining a certified test report in accordance with IMO type approval guidelines. The instrument has not been displayed at recent trade shows or exhibitions as it is not currently mandated by the market, and no commercial orders have been received to date. The Company continues to monitor market developments for potential future commercial opportunities for this product.

**Future Planning and Capital Requirements**

The Company anticipates that the costs of future product development and market expansion activities — including any acquisitions — would be funded from general working capital and, potentially, through arrangements with strategic partners in the shipping industry, funding from institutional investors, or private placements of the Company's securities. The Company has no current commitments for, and has received no binding indications of interest in connection with, any private placement of its securities. No assurance can be given that the Company's growth initiatives will succeed or continue to succeed.

**Product Distribution and Other Services**

**Scientific instruments**

The Company distributes analytical instruments, environmental quality monitoring instruments, sample pre-treatment equipment, and general purpose laboratory instruments. Analytical instruments distributed by the Company include, but are not limited to, chromatographs, Mass Spectrometers, flow injection analyzers, automated sample preparation workstations, and Atomic Spectrometers. Environmental monitoring instruments distributed by the Company include both air quality and water quality monitoring instruments. Air quality monitoring instruments are generally divided into those that monitor Ambient Air and those that monitor pollution sources. Revenues from the sale of air quality monitoring instruments are nominal, as the Company has been unable to secure distributorships for air quality instruments from brand-name manufacturers that primarily sell directly to customers or through their existing distributor networks. Sample pre-treatment equipment is used to prepare samples for chemical analysis, including the testing of pesticide and drug residues in food. General purpose laboratory instruments distributed by the Company include a variety of water quality monitoring and analysis equipment, such as continuous-reading process analyzers, process turbidimeters, pH controllers, and test kits for monitoring chemical content in water, including chlorine and fluoride concentrations. See "Glossary."

Customers for analytical instruments include government agencies, academic and research institutions, major laboratories, and beverage producers. The Company has supplied analytical systems to the Hong Kong Government Laboratory for the analysis of persistent organic pollutants ("POPs") and pesticides in the environment. Customers for water quality monitoring instruments also include government agencies. The Company derived approximately 58.9%, 51.6%, and 60.8% of its total revenues from the sale of scientific instruments during Fiscal 2025, Fiscal 2024, and 2023, respectively.

**Power solutions and process automation products**

The Company distributes general testing and measuring equipment, including multi-channel digital and analog recorders, signal amplifiers, calibration equipment, energy conservation and renewable energy equipment, power quality analyzers, and continuous emissions monitoring systems, to a broad range of industries including power generation, railway, aerospace, utilities, educational institutions, and telecommunications.

The Company also provides process control systems specifically designed for the industrial needs of its clients, including sensors, temperature and pressure gauges, power and energy consumption meters, flow meters, valves, temperature and pressure transmitters and control devices, temperature and pressure calibrators, and moisture, power, energy, and harmonic analyzers. Customers for these products include government water supply agencies, water treatment facilities, power and electric companies, petrochemical plants, and instrument manufacturers.

In conjunction with the distribution of programmable logic controllers, telemetry units, and supervisory control and data acquisition ("SCADA") systems and software, the Company also provides systems engineering services to government agencies, wastewater treatment and power generation plants, and beverage producers. Specific services include automated control system design and the operation and management of water, wastewater, and power generation projects. The Company has been cooperating with established technology companies on systems and special projects involving programmable logic control, telemetry units, SCADA systems, Human Machine Interface Software, and sequential event recording.

The Company derived approximately 38.6%, 46.5%, and 37.6% of its total revenues from the sale of power solutions and process automation products during Fiscal 2025, 2024, and 2023, respectively.

**Technical support**

The Company's technical support staff provides customers with maintenance, installation assistance, and calibration services, and assists sales personnel in providing technical advice and performing product demonstrations for customers. The Company derived approximately 2.5%, 1.9%, and 1.6% of its total revenues from technical support operations during Fiscal 2025, 2024, and 2023, respectively.

**Customers**

During Fiscal 2025, the Company distributed products to approximately 300 customers located in Hong Kong, mainland China, and Macau, including government agencies such as the Hong Kong Water Supplies Department, the Government Laboratory, and the Drainage Services Department, as well as universities and public utilities agencies. Sales to the Company's three largest customers amounted in the aggregate to approximately 35% of total revenues during Fiscal 2025, with one customer accounting for approximately 13% of total revenues.

During Fiscal 2024, the Company distributed products to approximately 300 customers located in Hong Kong, mainland China, and Macau, including government agencies such as the Hong Kong Water Supplies Department, the Government Laboratory, and the Drainage Services Department, as well as universities and public utilities agencies. Sales to the Company's three largest customers amounted in the aggregate to approximately 31% of total revenues during Fiscal 2024, with one customer accounting for approximately 15% of total revenues.

During Fiscal 2023, the Company distributed products to approximately 380 customers in Hong Kong, mainland China, and Macau, including the same categories of government and institutional customers noted above. Sales to the Company's three largest customers amounted in the aggregate to approximately 31% of total revenues during Fiscal 2023, with one customer accounting for approximately 14% of total revenues.

The number of customers served by the Company decreased significantly in prior years and has remained at approximately 300 to 380 in Fiscal 2023, Fiscal 2024, and Fiscal 2025, reflecting the ongoing contraction of the Company's distribution activities in mainland China as a greater number of the Company's suppliers have begun selling directly into the Chinese market. See "Item 4.B — Business Overview — Business Strategy" for a more detailed discussion.

**Sources of Supply**

The Company distributes products manufactured by major American, European, and Japanese corporations. The Company's four largest suppliers are Stanford, Thermo, Hach, and Hioki. Purchases from these four suppliers, expressed as a percentage of total purchases, were as follows:

---

| | | | |
|:---|:---|:---|:---|
| Supplier | Fiscal 2023 | Fiscal 2024 | Fiscal 2025 |
| Thermo | 42% | 26% | 32% |
| Stanford | 23% | 36% | 18% |
| Hach | 7% | 8% | 13% |
| Hioki | 5% | 5% | 6% |

---

The Company holds exclusivity agreements with many of its suppliers for specified geographic areas in respect of certain products. However, these agreements do not encompass all products distributed by the Company or all of the market areas serviced by the Company. Some of these arrangements are not memorialized in formal written contracts but are instead reflected in authorization letters or other correspondence that may not contain a complete description of the terms and conditions of the arrangement and may therefore be unenforceable.

The Company's principal supplier arrangements are as follows:

---

| |
|:---|
| **Thermo** — The Company holds an authorization certification from Thermo (currently valid until March 31, 2027) granting the Company rights to sell Thermo's Mass Spectrometry products to government agencies and hospitals in Hong Kong. |
| **Stanford** — The Company holds an Authorization Letter from Stanford appointing the Company as Stanford's sales representative in the PRC and Hong Kong. |
| **Hach** — The Company holds an Authorization Letter from Hach authorizing the Company as Hach's distributor in Hong Kong and Macau. |
| **Hioki** — The Company holds an Authorization Letter from Hioki appointing the Company as Hioki's sole agent in Hong Kong and Macau. |

---

Although alternative sources of supply exist for most of the products the Company distributes, there can be no assurance that the termination of the Company's relationship with any of these or other suppliers would not have a material adverse effect on the Company's business, financial condition, and results of operations.

**Regulatory Environment**

Awareness of pollution and environmental issues has grown significantly at all levels of PRC government in tandem with China's rapid economic development. Environmental protection laws and regulations have been progressively strengthened, and budget allocations for environmental regulation, monitoring, and enforcement have increased substantially. The PRC's primary environmental protection agency is the Ministry of Ecology and Environment ("MEE"), which was established following the 13th National People's Congress in March 2018 to replace the former Ministry of Environmental Protection ("MEP") and to consolidate environmental oversight functions under a single streamlined ministry.

China's 14th Five-Year Plan (2021–2025) sets out ambitious environmental targets, including the continued rectification of ecological and environmental problems, improvements to sewage and waste treatment infrastructure, and the development of an environmental infrastructure network extending from urban centers to towns and villages. The Plan also emphasizes improvements to ship pollution treatment in the Yangtze River basin and the Yellow River basin. Following the successful implementation of the Yangtze River Basin Protection Law, the Yellow River Basin Protection Law came into effect in April 2023 and the MEE organized investigation and remediation activities at approximately 4,000 wastewater discharge points across Shanxi, Inner Mongolia, Shandong, Henan, Sichuan, Shaanxi, Gansu, Qinghai, and Ningxia provinces and autonomous regions. The MEE has also prioritized the control of PM2.5 particulate matter and ozone concentrations, the reduction of nitrogen oxides ("NOx") and volatile organic compound ("VOC") emissions, and the strengthening of integrated pollution control in the border areas of Jiangsu, Anhui, Shandong, and Henan provinces. The MEE has encouraged service providers to adopt new technologies for the renovation of exhaust gas treatment facilities, particularly for VOC treatment.

In August 2020, the Ministry of Transport ("MT") issued the Measures for the Prevention and Control of Water Pollution from Inland River Vessels under 400 GT, which requires ships generating domestic sewage to install treatment devices or storage facilities to prevent domestic sewage from polluting inland waterways. Port management departments and maritime management agencies are required to urge port and shipping enterprises to accelerate the construction and renovation of relevant facilities. In March 2021, the MT, together with the MEE and other relevant departments, issued the Opinions on Establishing a Long-term Mechanism for the Prevention and Control of Pollution from Ships and Ports in the Yangtze River Economic Zone, which required the completion of ship sewage treatment renovations by the end of May 2022, implementing the requirements of the Water Pollution Prevention and Control Law of the PRC and the Yangtze River Protection Law of the PRC.

On January 1, 2024, the Amendment to the Marine Environmental Protection Law came into effect, pursuant to which the PRC government has strengthened the supervision and management of marine environmental pollution from ships operating in port areas.

Management believes that the tightening of environmental standards and the expansion of environmental infrastructure requirements in mainland China, as reflected in the foregoing regulatory developments, may benefit the Company's business by increasing demand for the water and wastewater treatment engineering services provided by Pact-Yixing and the environmental monitoring and testing products distributed by Far East. See "Item 4.B — Business Overview — Principal Activities" and "Item 3.D — Risk Factors — Changes in the Economic and Political Policies of the PRC Government could have a material and adverse effect on our business, financial condition and results of operations" for additional context.

**Competition**

The Company faces competition in its distribution activities from other distributors of comparable products as well as from manufacturers who sell their products directly into the Hong Kong and mainland China markets. The Company's principal competitors in its distribution activities are manufacturers and distributors of laboratory instruments, analyzers, water treatment equipment, and related products located in Hong Kong and mainland China.

The Company believes that it competes with Chinese manufacturers primarily on the basis of product quality and technology, as the foreign-manufactured products the Company distributes are generally of higher quality and incorporate more advanced technology than comparable domestically manufactured products. The Company believes that it competes with foreign manufacturers and other distributors of similar products primarily on the basis of its established reputation and long-standing customer relationships in Hong Kong and mainland China.

In its engineering and construction activities, Pact-Yixing focuses on providing industrial water and wastewater treatment solutions to large multinational manufacturing companies operating in mainland China. Pact-Yixing competes in this market on the basis of the quality of its engineering solutions and the expertise of its technical and engineering personnel. Pact-Yixing faces competition from large PRC and multinational engineering companies that the Company believes compete primarily on the basis of pricing rather than technical quality or service standards.

In its ballast water treatment systems business, Pact-Yixing competes with other manufacturers of IMO-approved ballast water treatment systems globally. The Company believes that Pact-Yixing's competitive strengths in this market include its proprietary technology, its positioning as one of the first companies in Asia to deliver a complete ballast water port solution system, and its focus on markets in Asia, the Middle East, and Europe in connection with the Belt and Road Initiative.

For the fiscal years ended December 31, 2025, 2024, and 2023, the Company's gross profit margins were approximately 28%, 29%, and 22%, respectively.

**Sales and Marketing**

The Company distributes products primarily through Far East, its wholly-owned subsidiary in Hong Kong, utilizing a direct marketing and sales force as its principal channel for customer engagement. The Company's sales staff work directly with customers to identify appropriate products and solutions, assist customers in selecting equipment, accessories, and related supplies to suit their specific requirements, and provide technical support and after-sales assistance. The Company's sales force is compensated through a combination of base salary and performance-based sales commissions.

For the fiscal years ended December 31, 2025, 2024, and 2023, the Company's marketing and sales force consisted of approximately 11, 11, and 7 individuals, respectively. The increase in sales force headcount in Fiscal 2024 reflects the Company's efforts to expand its customer base and strengthen its sales capabilities in Hong Kong and mainland China.

**Major Customers**

The Company's revenues are partially dependent on sales to a limited number of significant customers, and the loss of any one of these customers could have a material adverse effect on the Company's results of operations. For each of the fiscal years ended December 31, 2025, 2024, and 2023, sales to the Company's three largest customers amounted in the aggregate to approximately 35%, 31%, and 31% of total revenues, respectively. The Company does not have long-term purchase commitments from any of its major customers, and there can be no assurance that such customers will continue to purchase products and services from the Company at historical levels or at all.

**Seasonality** 

Our engineering and construction activities are subject to seasonal variation. Construction of water and wastewater treatment systems is typically slower during the winter months due to adverse weather conditions in northern mainland China, which can affect outdoor construction activity and the transportation of equipment and materials. Construction activity also slows during major PRC public holidays — most notably the Spring Festival (Chinese New Year) holiday period — as government agencies, client facilities, and project sites are closed or operating at reduced capacity for extended periods. These seasonal factors may result in variability in our revenues and results of operations from quarter to quarter.

**Litigation**

From time to time, we are subject to legal proceedings, investigations and claims incidental to the conduct of our business. We are not currently a party to any legal proceeding or investigation which, in the opinion of our management, is likely to have a material adverse effect on our business, financial condition or results of operations.

**Regulations**

**Regulations on corporate governance**

On December 29, 2023, the Standing Committee of the National People's Congress promulgated the Amended PRC Company Law, which came into effect on July 1, 2024, superseding the existing PRC Company Law previously amended in October 2018. The Amended PRC Company Law made material amendments to corporate governance and shareholders' rights of PRC companies, including, among others, the statutory period for payment of registered capital, the composition of the board of directors and the board of supervisors, and the transfer of equity interests.

With respect to the period for payment of the registered capital, all shareholders of a PRC limited liability company are required to fully pay up their subscribed registered capital within five years from the date of establishment.

Companies established before the effective date of the Amended PRC Company Law are required to amend their articles of association to comply with the new time limits, and companies whose period of capital contribution or amount of registered capital is obviously abnormal may be required by the competent authority to make adjustments. If a shareholder fails to make capital contributions on schedule and in full, the company shall issue a written notice requiring payment within a grace period of no less than sixty days. If the shareholder fails to comply upon expiration of the grace period, the company may, upon a resolution of the board of directors, issue a written forfeiture notice, and the shareholder shall forfeit the equity interests in respect of which capital contributions remain unpaid. On July 1, 2024, the State Council issued the Provisions on Implementing the Registered Capital Registration and Management System under the PRC Company Law, providing for a three-year interim period from July 1, 2024 to June 30, 2027 during which existing companies may adjust their periods of capital contribution to comply with the Amended PRC Company Law. The adjusted period of capital contribution shall be recorded in the company's articles of association and publicized through the national enterprise credit information publicity system.

With respect to the board of directors and the board of supervisors, the Amended PRC Company Law eliminates the upper limit on the number of directors of a limited liability company, and stipulates that a limited liability company without an employee representative among its board of supervisors but with more than 300 employees shall include an employee representative as a director, to be democratically elected by the company's employees. Limited liability companies, joint stock limited companies with a small scale or small number of shareholders, and wholly state-owned companies may establish an audit committee to replace the board of supervisors and need not appoint any supervisor.

With respect to the transfer of equity interests, the Amended PRC Company Law stipulates that shareholders of a limited liability company may transfer their equity interests without the consent of other shareholders, provided that the transferring shareholder shall notify the other shareholders in writing. Other shareholders will be deemed to have waived their right of first refusal if they fail to reply within 30 days of receiving the written notice. If a shareholder transfers its equity interest, it shall notify the company in writing to request the company to update the register of shareholders and register the change with the competent enterprise registration authority. If the company refuses or fails to respond, the transferee and transferor may file a lawsuit with the competent court.

**Regulations on environmental protection**

The Company's engineering and distribution activities are subject to a range of PRC environmental laws and regulations. The principal legislation governing environmental protection in mainland China includes the Environmental Protection Law of the PRC, as amended and effective from January 1, 2015, which establishes the general framework for environmental protection, sets out the responsibilities of enterprises for preventing and controlling pollution, and provides for a system of environmental impact assessments, emissions standards, and regulatory inspections. The Environmental Protection Law imposes penalties — including fines, suspension of operations, and criminal liability — for violations of applicable environmental standards and requirements.

The Water Pollution Prevention and Control Law of the PRC, as amended and effective from January 1, 2018, governs the prevention and control of water pollution in mainland China. Under this law, entities that discharge pollutants into water bodies are required to obtain pollutant discharge permits and comply with applicable water quality standards. Industrial enterprises are required to install, operate, and maintain water pollution treatment facilities that meet applicable standards, and are prohibited from discharging untreated or inadequately treated industrial wastewater.

China's 14th Five-Year Plan (2021–2025) sets out ambitious targets for environmental quality improvement, including targets for reductions in chemical oxygen demand, ammonia nitrogen, nitrogen oxides, and volatile organic compound emissions, as well as targets for improvements in surface water quality. The Plan also emphasizes the development of green industries and clean production technologies. Management believes that the regulatory direction reflected in the 14th Five-Year Plan, and the continued tightening of environmental standards in mainland China, may benefit the Company's engineering and distribution activities by increasing demand for water treatment solutions and environmental monitoring equipment of the type the Company and Pact-Yixing provide. See "Item 4.B — Business Overview" for a more detailed description of the Company's environmental technology business.

**Regulations on product import and distribution**

The importation of goods into mainland China is governed by the Customs Law of the PRC, as amended, and the regulations promulgated thereunder by the General Administration of Customs. Imported goods are subject to customs duties, import VAT, and applicable regulatory requirements. Certain categories of imported goods — including laboratory instruments, analytical equipment, and water treatment equipment — may be subject to product certification requirements administered by the State Administration for Market Regulation or other competent authorities before they may be distributed or sold within mainland China.

Foreign-invested enterprises engaged in distribution activities in mainland China are subject to applicable foreign investment restrictions and are required to operate within the approved scope of their business licenses. Distributors of certain categories of goods may be required to obtain additional approvals, licenses, or certifications from relevant regulatory authorities.

Changes in PRC customs regulations, import duties, product certification requirements, or distribution licensing requirements could materially affect the Company's ability to source, import, and distribute products in mainland China. In addition, certain products of U.S. origin distributed by the Company may be subject to U.S. export control laws and regulations that restrict or prohibit their export to mainland China. See "Item 3.D — Risk Factors — U.S. export control laws and regulations, including restrictions on the export of certain products to China, may adversely affect our ability to distribute products and could have a material adverse effect on our business and results of operations" for a discussion of U.S. regulatory risks that may affect the Company's ability to source and distribute products of U.S. origin.

Additionally, changes in applicable tariff rates — including retaliatory tariffs imposed by the PRC on goods of U.S. origin — could increase the cost of imported products and adversely affect the Company's pricing and margins in the mainland China market. See "Item 3.D — Risk Factors — Certain Risks Relating to Doing Business in China — Escalating U.S.-China trade tensions and tariff measures may materially and adversely affect our business, results of operations, and the price of our securities" for a more detailed discussion of trade-related risks.

**Regulations on ballast water treatment**

The International Convention for the Control and Management of Ships' Ballast Water and Sediments (the "BWM Convention"), adopted by the International Maritime Organization ("IMO") in 2004 and entered into force on September 8, 2017, requires ships engaged in international voyages to manage their ballast water and sediments to a certain standard in order to prevent the spread of potentially invasive aquatic organisms and pathogens. Under the BWM Convention, ships are required to implement a ballast water management plan and to comply with applicable ballast water performance standards. The BWM Convention requires ships to be fitted with an approved ballast water management system ("BWMS") that has been type-approved by the relevant flag state authority in accordance with IMO guidelines.

In mainland China, ballast water treatment is regulated by the Maritime Safety Administration of the PRC (the "MSA") under the Regulations on the Prevention and Control of Pollution from Ships, as amended. Ballast water treatment systems sold for installation on ships operating in Chinese waters or registered under the PRC flag are required to comply with applicable MSA type-approval requirements.

The ongoing implementation of the BWM Convention across the global shipping fleet is the primary driver of demand for Pact-Yixing's BWTS products. Changes in IMO regulations, type-approval standards, or implementation timelines — or changes in PRC maritime regulations governing BWTS — could affect demand for Pact-Yixing's BWTS products or the Company's ability to sell them in certain markets.

**Regulations on intellectual property rights**

*Patent*

Patents in mainland China are principally protected under the PRC Patent Law, which was initially promulgated by the Standing Committee of the National People's Congress in 1984 and was most recently amended in 2020. A patent is valid for twenty years in the case of an invention, fifteen years in the case of designs, and ten years in the case of utility models. As of December 31, 2025, the Company had registered 7 patents and had 1 patent application pending in mainland China.

*Trademark*

Registered trademarks are protected under the PRC Trademark Law, adopted by the Standing Committee of the National People's Congress in 1982 and most recently amended in 2019, and the Implementation Regulations of the PRC Trademark Law adopted by the State Council in 2002 and most recently amended in 2014 and other related rules and regulations. The China National Intellectual Property Administration ("CNIPA") handles trademark registrations and grants a protection term of ten years to registered trademarks, renewable for additional ten-year periods upon request. As of December 31, 2025, the Company had registered 3 trademarks in mainland China with the CNIPA.

*Domain Names*

Domain names are protected under the Administrative Measures on Internet Domain Names promulgated by the MIIT on August 24, 2017 and effective from November 1, 2017. Pursuant to the Notice of the MIIT on Regulating the Use of Domain Names in Providing Internet-based Information Services, effective January 1, 2018, the domain name used by an internet-based information service provider must be registered and owned by such provider in accordance with applicable law. If the provider is an entity, the domain name registrant must be the entity (or any of its shareholders), or the entity's principal or senior management. As of December 31, 2025, the Company had registered 8 domain names in mainland China, including both active and administrative domain names.

**Regulations on Internet information security, censorship and privacy protection**

The PRC Cybersecurity Law, which originally took effect in June 2017, was amended by the Standing Committee of the National People's Congress on October 28, 2025, with the amended law taking effect on January 1, 2026 (as amended, the "PRC Cybersecurity Law"). The PRC Cybersecurity Law governs the construction, operation, maintenance, and use of networks in China and subjects network operators to various security protection obligations. The PRC Cybersecurity Law also provides that personal information and important data collected and generated by operators of critical information infrastructure ("CII") in the course of their operations in the PRC must be stored within the PRC, and imposes heightened regulation and additional security obligations on such operators. Among the key changes introduced by the 2025 amendment, the revised PRC Cybersecurity Law significantly strengthens the legal liabilities applicable to violations of cybersecurity obligations, including by imposing materially higher penalties for non-compliance.

On June 10, 2021, the Standing Committee of the National People's Congress promulgated the PRC Data Security Law, effective September 2021, which imposes data security and privacy obligations on entities and individuals carrying out data activities and introduces a data classification and hierarchical protection system based on the importance of data in economic and social development and the degree of harm that would result from its compromise, destruction, leakage, or unauthorized acquisition or use. Processors of important data are required to designate personnel and a management body responsible for data security, carry out risk assessments, and file assessment reports with the competent authorities. The PRC Data Security Law also provides a national security review procedure for data activities affecting or potentially affecting national security and imposes export restrictions on certain data and information.

The Cybersecurity Review Measures originally promulgated in April 2020 were superseded by the Revised Cybersecurity Review Measures jointly issued by the CAC and other PRC authorities on December 28, 2021, effective February 15, 2022. Under the Revised Cybersecurity Review Measures, operators of critical information infrastructure that intend to purchase network products and services affecting or potentially affecting national security must apply for a cybersecurity review. As of the date of this Annual Report, we have not been involved in any investigations or become subject to a cybersecurity review initiated by the CAC, and we have not received any inquiry, notice, warning, or sanction in such respect or any regulatory objection to our listing status from the CAC.

On July 30, 2021, the PRC State Council promulgated the Regulations on Security Protection of Critical Information Infrastructures, effective September 1, 2021. These regulations define critical information infrastructures as important network facilities or information systems of important industries or fields — such as public communications, energy, transportation, water resources, finance, public services, e-government affairs, and national defense — whose damage, loss of function, or data leakage may endanger national security, people's livelihood, or the public interest. Administration departments for each critical industry are responsible for determining which operators qualify as critical information infrastructure operators. As of the date of this Annual Report, we have not been involved in any cybersecurity review investigations nor received any inquiry, notice, warning, or sanction in such respect.

On September 24, 2024, the State Council issued the Cyber Data Security Administration Regulations, which came into effect on January 1, 2025. Data processors are required to conduct a risk assessment before providing, entrusting, or jointly processing important data. If data processors operating within China need to transfer important data collected or generated domestically to overseas recipients, they must undergo a data export security assessment organized by the CAC. See "Item 3.D — Risk Factors — Our Failure to Comply with PRC Cybersecurity and Data Protection Laws and Regulations — Including the Cyber Data Security Administration Regulations Effective January 1, 2025 **—** Could Lead to Government Enforcement Actions, Significant Penalties, and an Adverse Effect on Our Operating Results" for a more detailed discussion of the risks associated with these regulations.

Our business does not involve the collection, processing, or transfer of significant volumes of personal data of third parties, and we do not believe we are subject to the heightened obligations applicable to large-scale personal data processors under the applicable PRC regulatory framework. Based on our current assessment, we believe that, as of the date of this Annual Report, we are in compliance in all material respects with the applicable PRC laws and regulations on cybersecurity, data security, and personal data protection.

On July 7, 2022, the CAC promulgated the Measures for the Security Assessment of Cross-border Data Transfer, effective September 1, 2022. Under these measures, data processors are subject to a CAC security assessment prior to any cross-border transfer of data involving: (i) important data; (ii) personal information transferred overseas by operators of critical information infrastructure or by a data processor that has processed personal data of more than one million persons; (iii) personal information transferred overseas by a data processor that has already provided personal data of 100,000 persons or sensitive personal data of 10,000 persons overseas since January 1 of the preceding year; or (iv) other circumstances as required by the CAC. The interpretation and implementation of these measures in practice continue to evolve, and there remain uncertainties as to how they may affect our business operations.

On August 20, 2021, the Standing Committee of the National People's Congress promulgated the PRC Personal Information Protection Law ("PIPL"), effective November 1, 2021. The PIPL defines personal information as information related to an identified or identifiable individual recorded electronically or by other means, excluding anonymized information, and defines processing to include the collection, storage, use, handling, transmission, provision, disclosure, and deletion of personal information. The PIPL sets forth lawful bases for processing personal information — including obtaining the individual's consent, necessity for the performance of a contract to which the individual is a party, and compliance with statutory duties or obligations — and requires processors to clearly inform individuals of the purposes, methods, types, and retention period of processing, as well as the methods and procedures by which individuals may exercise their rights. Individuals have the right to withdraw consent at any time, and processors must not refuse to provide products or services solely on the grounds that an individual has declined to consent or has withdrawn consent, unless processing is necessary for the provision of those products or services. Any processor in violation of the PIPL may be subject to administrative penalties including rectification orders, warnings, fines, suspension of business, revocation of business licenses, and civil or criminal liabilities.

While we take measures to comply with all applicable data privacy and protection laws and regulations, we cannot guarantee the effectiveness of the measures undertaken by us or implemented by our business partners. As certain laws and regulations, including the PRC Data Security Law and the PIPL, continue to evolve, we may be required to make further adjustments to our business practices to ensure ongoing compliance.

**Regulations on foreign exchange**

Under the PRC Foreign Exchange Administration Rules and various regulations issued by the State Administration of Foreign Exchange ("SAFE") and other PRC government authorities, Renminbi is convertible into other currencies for current account items, such as trade-related receipts and payments and the payment of interest and dividends. The conversion of Renminbi into other currencies and the remittance of converted foreign currency outside mainland China for capital account items — such as direct equity investments, loans, and repatriation of investment — requires the prior approval of SAFE or its local office. Payments for transactions within mainland China must be made in Renminbi, and mainland China companies may not repatriate or retain foreign currency payments received from abroad without approval. Foreign-invested enterprises may retain foreign exchange in accounts with designated foreign exchange banks under current account items, subject to caps set by SAFE. Foreign exchange proceeds under current account items may be retained or sold to authorized financial institutions; proceeds under capital account items generally require SAFE approval for retention or sale.

SAFE has issued a series of circulars over the years that have progressively simplified and liberalized foreign exchange administration for direct investment activities. In summary: SAFE Circular 59 (2012, as amended in 2018) removed the requirement for SAFE approval to open foreign exchange accounts and simplified registration procedures for foreign investors acquiring equity interests in Chinese companies. SAFE Circular 13 (2015, as amended in 2019) further simplified foreign exchange registration for direct domestic and overseas investment by allowing investors to register directly with banks rather than SAFE. SAFE Circular 19 (2015) permits foreign-invested enterprises to settle 100% of their foreign exchange capital on a discretionary basis, provided that capital is used for the enterprise's own operational purposes within its scope of business. SAFE Circular 16 (2016) extended the self-discretionary conversion framework to foreign debts and established an integrated standard for conversion of foreign exchange under capital account items for all enterprises registered in mainland China. SAFE Circular 3 (2017) introduced capital control measures for the outbound remittance of profits from domestic entities to offshore entities, requiring banks to verify the genuineness of transactions by reviewing board resolutions, tax filing records, and audited financial statements, and requiring domestic entities to account for prior years' losses before remitting any profits. SAFE Notice 28 (2019) permits non-investment foreign-invested enterprises to use capital funds to make equity investments in mainland China in connection with genuine investment projects and in compliance with applicable foreign investment restrictions.

Pursuant to SAFE Circular 13 and other applicable foreign exchange regulations, when establishing a new foreign-invested enterprise, the enterprise shall register with the bank at its registered place after obtaining its business license. Any subsequent material changes — including any increase in registered capital or total investment — shall be registered with the bank after obtaining required approval from or completing the required filing with the competent authorities. Such foreign exchange registration with banks will typically be completed within four weeks of acceptance of the registration application.

If the Company intends to provide funding to its wholly foreign-owned subsidiaries through capital injection at or after their establishment, it shall register the establishment of, and any subsequent capital increase in, such subsidiaries with the State Administration for Market Regulation or its local counterparts, file such registration via the foreign investment comprehensive management information system, and complete the corresponding foreign exchange registration with the local banks.

**Regulations on foreign investment**

The Foreign Investment Law of the PRC, effective from January 1, 2020, and its implementing regulations, the Regulation on Implementing the Foreign Investment Law, effective from the same date, establish the principal legal framework governing foreign investment in mainland China. The Foreign Investment Law replaced the three prior laws governing foreign-invested enterprises — the Sino-foreign Equity Joint Venture Enterprise Law, the Sino-foreign Cooperative Joint Venture Enterprise Law, and the Wholly Foreign-owned Enterprise Law — and introduced a unified regulatory framework applicable to all forms of foreign investment in mainland China.

Under the Foreign Investment Law and its implementing regulations, foreign investment in mainland China is subject to a negative list system administered by the National Development and Reform Commission and the Ministry of Commerce. Industries on the negative list are either prohibited from foreign investment or subject to restrictions on the form or extent of foreign ownership. Industries not on the negative list are generally open to foreign investment on the same terms as domestic investment. The Special Administrative Measures (Negative List) for Foreign Investment Access sets out the current negative list applicable to foreign investment in mainland China.

The Foreign Investment Law provides that the legitimate rights and interests of foreign investors and their investments in mainland China shall be protected in accordance with law, and that the PRC government shall not expropriate foreign investments except in special circumstances and for public interest purposes, in which case fair and reasonable compensation shall be paid in a timely manner.

Yixing, the Company's 58%-owned subsidiary incorporated in mainland China, is a foreign-invested enterprise subject to the Foreign Investment Law and its implementing regulations. Changes in the foreign investment regulatory framework — including changes to the negative list or to the regulatory treatment of foreign-invested enterprises in the water treatment or environmental technology sectors — could affect the Company's ability to operate Yixing or to expand its operations in mainland China.

**Regulations on dividend distribution**

The principal laws and regulations governing the distribution of dividends by foreign-invested enterprises in mainland China include the Amended PRC Company Law, the Foreign Investment Law, and the Regulation on Implementing the Foreign Investment Law. Under the current regulatory regime in mainland China, foreign-invested enterprises in mainland China may pay dividends only out of their accumulated retained earnings, if any, determined in accordance with PRC accounting standards and regulations. A mainland China company is required to set aside as statutory reserve funds at least 10% of its after-tax profit each year, until the cumulative amount of such reserve funds reaches 50% of its registered capital, unless otherwise provided by applicable laws and regulations. A mainland China company shall not distribute any profits until any losses from prior fiscal years have been fully offset. Profits retained from prior fiscal years may be distributed together with distributable profits from the current fiscal year.

**Regulations on anti-corruption and anti-bribery**

The Anti-Unfair Competition Law of the PRC, as amended and effective from April 23, 2022, prohibits commercial bribery, which is defined as providing or offering money, goods, or other benefits to counterparties, third parties related to the transaction, or government officials in order to obtain a business opportunity or competitive advantage. The PRC Criminal Law also contains provisions that criminalize the payment of bribes to government officials and employees of state-owned enterprises. Violations of anti-corruption laws and regulations in mainland China may result in significant fines, criminal liability, and reputational damage.

The Company is also subject to the U.S. Foreign Corrupt Practices Act (the "FCPA") by virtue of its listing on the Nasdaq Capital Market. The FCPA prohibits U.S. issuers and their affiliates from making corrupt payments to foreign government officials for the purpose of obtaining or retaining business. Violations of the FCPA may result in significant civil and criminal penalties. The Company has implemented internal compliance measures designed to ensure compliance with applicable anti-corruption laws and regulations in the jurisdictions in which it operates.

**Regulations on taxation**

Enterprise Income Tax

On March 16, 2007, the Standing Committee of the National People's Congress promulgated the Enterprise Income Tax Law, subsequently amended on February 24, 2017 and December 29, 2018. The State Council enacted the Regulations for the Implementation of the Enterprise Income Tax Law on December 6, 2007, effective from January 1, 2008 and most recently amended on December 6, 2024. Under the Enterprise Income Tax Law and its implementing regulations, both resident enterprises and non-resident enterprises are subject to tax in mainland China. Resident enterprises are defined as enterprises established in mainland China in accordance with PRC laws, or enterprises established under the laws of foreign countries whose actual management is conducted from within mainland China. Non-resident enterprises are defined as enterprises organized under the laws of foreign countries whose actual management is conducted outside mainland China but that have established institutions or premises in mainland China or that derive income from within mainland China. A uniform corporate income tax rate of 25% applies to resident enterprises. Non-resident enterprises that have not formed permanent establishments in mainland China, or whose permanent establishments have no actual connection to their mainland China-sourced income, are subject to enterprise income tax at the rate of 10% on their income sourced from within mainland China.

Value-Added Tax

The principal legislation governing value-added tax ("VAT") in mainland China includes the Provisional Regulations of the PRC on Value-added Tax, as most recently amended in November 2017, and the related Detailed Rules for Implementation. All enterprises and individuals engaged in the sale of goods, the provision of processing, repair and replacement services, sales of services, intangible assets, or real property, and the importation of goods within mainland China are subject to VAT. The currently applicable standard VAT rates are 13% and 9% for most categories of taxable goods and services, with a 6% rate applicable to certain service categories, following successive rate adjustments made in 2018 and 2019. As of the date of this Annual Report, our mainland China subsidiaries are generally subject to VAT at rates of 3%, 6%, 9%, or 13%, together with related surcharges.

Dividend Withholding Tax

The Enterprise Income Tax Law provides that, from January 1, 2008, an income tax rate of 10% is normally applicable to dividends declared to non-mainland China resident enterprise investors that do not have an establishment or place of business in mainland China, or whose establishment or place of business in mainland China is not effectively connected with the relevant income, to the extent such dividends are derived from sources within mainland China.

Pursuant to the Arrangement Between the Mainland of China and the Hong Kong Special Administrative Region for the Avoidance of Double Taxation and the Prevention of Fiscal Evasion with Respect to Taxes on Income and other applicable PRC laws, if a Hong Kong resident enterprise is determined by the competent PRC tax authority to have satisfied the applicable conditions and requirements, the 10% withholding tax on dividends received by the Hong Kong resident enterprise from a mainland China resident enterprise may be reduced to 5%. However, pursuant to SAT Circular 81 issued by the State Administration of Taxation on February 20, 2009, if the PRC tax authorities determine that a company benefits from such reduced tax rate due to a structure or arrangement that is primarily tax-driven, the preferential tax treatment may be adjusted. In determining an applicant's status as a "beneficial owner" for purposes of the reduced withholding tax rate, the tax authorities will consider several factors, including whether the applicant is obligated to pay more than 50% of its income over a twelve-month period to residents of a third country or region, whether the business operated by the applicant constitutes actual business activities, and whether the counterparty jurisdiction to the tax treaty does not levy any tax, exempts the relevant income from tax, or levies tax at an extremely low rate.

Tax on Indirect Transfer

On February 3, 2015, the State Administration of Taxation issued the Circular on Issues of Enterprise Income Tax on Indirect Transfers of Assets by Non-PRC Resident Enterprises. Pursuant to this circular, an "indirect transfer" of assets — including equity interests in a mainland China resident enterprise — by a non-mainland China resident enterprise may be recharacterized and treated as a direct transfer of mainland China taxable assets if such arrangement does not have a reasonable commercial purpose and was established for the purpose of avoiding mainland China enterprise income tax. Gains derived from such indirect transfer may accordingly be subject to mainland China enterprise income tax. Factors relevant to determining whether there is a "reasonable commercial purpose" include whether the main value of the equity interest of the offshore enterprise derives directly or indirectly from mainland China taxable assets, whether the assets of the offshore enterprise mainly consist of direct or indirect investments in mainland China or whether its income is mainly derived from mainland China, and whether the offshore enterprise and its subsidiaries that directly or indirectly hold mainland China taxable assets have a genuine commercial character as evidenced by their actual functions and risk exposure. Where the payor fails to withhold any or sufficient tax, the transferor is required to declare and pay such tax to the tax authority within the statutory time limit. Late payment of applicable tax will subject the transferor to default interest. The circular does not apply to sales of shares by investors through a public stock exchange where such shares were acquired on a public stock exchange. SAT Circular 37, issued on October 17, 2017 and amended on June 15, 2018, further elaborates the implementation rules regarding the calculation, reporting, and payment obligations of the withholding tax by non-resident enterprises. There remain uncertainties as to the interpretation and application of these circulars, and they may be determined by the tax authorities to be applicable to our offshore transactions or sales of our shares or those of our offshore subsidiaries where non-resident enterprises, acting as transferors, are involved.

 **Regulations on Employment and Social Welfare**

Labor Contract Law

The PRC Labor Contract Law, effective from January 1, 2008 and amended on December 28, 2012, regulates the rights and obligations of employer and employee relationships, including the establishment, performance, and termination of labor contracts. Labor contracts shall be concluded in writing if employment relationships are to be established. Employers are prohibited from requiring employees to work beyond statutory time limit and shall pay employees for overtime work in accordance with national regulations. Employee wages shall be no lower than applicable local minimum wage standards and shall be paid to employees on time.

Social Insurance and Housing Fund

Pursuant to the PRC Social Insurance Law, implemented on July 1, 2011 and most recently amended on December 29, 2018, and the Regulations on the Administration of Housing Funds, promulgated by the State Council in 1999 and most recently amended in 2019, employers in mainland China are required to provide employees with welfare schemes covering pension insurance, unemployment insurance, maternity insurance, work-related injury insurance, medical insurance, and housing fund contributions.

Employee Stock Incentive Plan

Pursuant to SAFE Circular 7, issued by SAFE on February 15, 2012, mainland China citizens or non-mainland China citizens residing in mainland China for a continuous period of no less than one year who participate in any stock incentive plan of a publicly listed overseas company are generally required to register with SAFE through a qualified domestic agent — which may be a mainland China subsidiary of such overseas listed company — and complete certain other prescribed procedures. In addition, employees working in mainland China who exercise stock options or are granted restricted shares will be subject to mainland China individual income tax. The mainland China subsidiaries of an overseas listed company are required to file documents related to employee stock options and restricted shares with the relevant tax authorities and to withhold individual income taxes accordingly. Failure by employees to pay, or failure by mainland China subsidiaries to withhold, individual income tax in accordance with applicable laws and regulations may result in sanctions being imposed on the mainland China subsidiaries by the relevant PRC governmental authorities.

**M&A Rules and Overseas Listing**

On August 8, 2006, six PRC governmental and regulatory agencies, including the Ministry of Commerce and the CSRC, promulgated the Regulations on Mergers and Acquisitions of Domestic Enterprises by Foreign Investors, effective September 8, 2006 and revised on June 22, 2009. The regulations require, among other things, that if an overseas company established or controlled by mainland China companies or individuals intends to acquire equity interests or assets of a mainland China domestic company affiliated with such mainland China individuals, the acquisition must be submitted to the Ministry of Commerce for approval. The regulations also require that an offshore special purpose vehicle formed for overseas listing purposes and controlled directly or indirectly by mainland China citizens shall obtain CSRC approval prior to the overseas listing and trading of its securities on an overseas stock exchange. On July 6, 2021, the General Office of the Central Committee of the Communist Party of China and the General Office of the State Council jointly promulgated the Opinions on Strictly Cracking Down on Illegal Securities Activities in Accordance with the Law, which called for the strengthening of regulatory oversight of overseas listings by Chinese companies and the development of regulatory frameworks to address risks associated with China-based overseas listed companies, including cybersecurity and data privacy protection requirements. Any related implementing rules enacted pursuant to these opinions may subject us to additional compliance requirements in the future.

On February 17, 2023, the CSRC published the Interim Administrative Measures on Overseas Securities Offering and Listing by Domestic Enterprises (the "Overseas Listing Measures"), effective March 31, 2023. Under the Overseas Listing Measures, a filing-based regulatory system applies to indirect overseas offerings and listings by PRC domestic companies — that is, securities offerings and listings in an overseas market made under the name of an offshore entity but based on the underlying equity, assets, earnings, or other similar rights of a domestic company that operates its main business in mainland China. Any overseas offering of securities — including shares, convertible notes, and other similar securities — and any overseas listing by a PRC domestic company shall be subject to a filing requirement to be completed within three business days after completion of such offering or listing. Pursuant to the accompanying Notice on the Administrative Arrangements for the Filing of Overseas Securities Offering and Listing by Domestic Enterprises published on the same date, issuers already listed in an overseas market as of March 31, 2023 — including the Company — are not required to make any immediate filing. However, such issuers will be required to comply with the filing requirements under the Overseas Listing Measures if and when they pursue any future securities offerings or listings outside of mainland China, including follow-on offerings, secondary listings, and going-private transactions.

**ITEM 5. OPERATING AND FINANCIAL REVIEW AND PROSPECTS** 

The following discussion and analysis of our financial condition and results of operations should be read in conjunction with our audited consolidated financial statements and the related notes included in this Annual Report and in particular, "Item 4. Information on the Company — B. Business Overview." This discussion contains forward-looking statements that involve risks and uncertainties. Our actual results and the timing of selected events could differ materially from those anticipated in these forward-looking statements as a result of various factors, including those set forth under "Item 3. Key Information — D. Risk Factors" and elsewhere in this Annual Report. We have prepared our consolidated financial statements in accordance with U.S. GAAP.

**A. OPERATING RESULTS**

**Business Overview**.

The Company organizes its business into two operating segments:

· **Trading and manufacturing** - the Company acts as a distributor of a wide range of advanced water treatment equipment, laboratory instruments, analyzers, test kits, related supplies, and power generation equipment (including recorders and power quality analyzers); and

· **Engineering** - the Company, through its majority-owned subsidiary Pact-Yixing and its minority-owned affiliate Blue Sky, engages in water and wastewater treatment engineering and air pollution control.

**Overview of Financial Performance**

Total revenue decreased by 14.3% to US$15,383,000 in Fiscal 2024 and decreased by 13.8% to US$13,265,000 in Fiscal 2025. Net income decreased by 59.8% to US$734,000 in Fiscal 2024 and decreased by 78.6% to US$157,000 in Fiscal 2025.

Key Factors Affecting Operating Results

The following is a discussion of the key factors that have affected, and are expected to continue to affect, the Company's operating results, financial condition, and future growth prospects.

**Key Factors Affecting Operating Results**

**BWTS business performance** 

The Company's BWTS business performed strongly in both mainland China and international markets during Fiscal 2023 and Fiscal 2024, driven primarily by increasing demand in the maritime industry spurred by the IMO Ballast Water Management Convention requirements and increasingly stringent local environmental regulations. In Fiscal 2025, sales of BWTS for ship vessels declined as the market for medium to large ship retrofits approached equilibrium. This decline was partially offset by an increase in port BWT solution sales in mainland China, which increased from one unit in Fiscal 2024 to two units in Fiscal 2025. In light of these trends, the Company intends to place greater strategic emphasis on the development and commercialization of its port BWT solutions business, while continuing to serve demand in the vessel retrofit and shipbuilding segments. The Company has particularly observed strong demand from the energy-related shipping industry in the Middle East and from petrochemical port operators in mainland China, and expects demand for its BWTS products to remain a significant driver of revenue in the near term, subject to global shipping market conditions and the pace of regulatory enforcement across key jurisdictions.

The Company notes that ongoing geopolitical instability in the Middle East — including regional conflicts and disruptions to maritime trade routes — has introduced, and is expected to continue to introduce, uncertainty into the Company's ability to maintain and grow its BWTS business in that region. The Company anticipates that sales of BWTS products for retrofit projects in the Middle East may be further affected by these developments in the near term. Disruptions to shipping lanes or a reduction in commercial shipping activity in the Middle East could adversely affect demand from the energy-related shipping sector, which has been a significant source of BWTS revenue. The Company continues to monitor developments in this region and their potential impact on its business, and will update its disclosure as circumstances warrant.

**Wastewater treatment and environmental engineering operations**

The Company's wastewater treatment and environmental engineering business — conducted primarily through Far East and its subsidiaries, including Pact Singapore and Yixing — has been and is expected to continue to be affected by the level of capital expenditure committed by industrial and municipal customers to environmental compliance projects in mainland China, Hong Kong, and Southeast Asia. Demand for the Company's wastewater treatment engineering services is closely correlated with the regulatory environment in mainland China, including the enforcement of environmental protection standards by PRC government authorities and the prioritization of environmental infrastructure investment in national and regional development plans. Tightening of environmental standards and increased enforcement activity in mainland China are expected to support demand for the Company's environmental engineering services. However, any slowdown in industrial activity, reduction in government infrastructure spending, or deterioration in the economic environment in the Company's key markets could adversely affect customer capital expenditure decisions and reduce demand for the Company's products and services.

**Geographic and customer concentration**

The Company derives a substantial portion of its revenues from customers in mainland China and Hong Kong. This geographic concentration means that the Company's operating results are particularly sensitive to economic, regulatory, and political developments in these markets. In addition, the Company's revenue base is concentrated among a relatively small number of customers in certain product and service categories, and the loss of any one or more significant customers, or a material reduction in orders from such customers, could have a disproportionate adverse effect on the Company's revenues and results of operations. The Company's ability to diversify its geographic and customer base — including through expansion of its BWTS business in international markets such as the Middle East — is therefore an important factor affecting its long-term revenue stability and growth prospects.

**Foreign currency fluctuations**

The Company's operating results are affected by fluctuations in exchange rates, particularly between the U.S. dollar — in which the Company reports its financial results — and the currencies in which the Company conducts its business operations, primarily the Hong Kong Dollar, Renminbi, Japanese yen, and euro. As described in greater detail under "Risk Factors — Because a portion of the Company's revenues are generated in Renminbi and the Company's results are reported in U.S. Dollars, fluctuations in the value of the Renminbi could negatively impact the Company's results of operations," the Renminbi experienced depreciation against the U.S. Dollar during Fiscal 2022 and continued depreciation pressure during Fiscal 2023, Fiscal 2024, and Fiscal 2025, which has affected the U.S. Dollar value of the Company's RMB-denominated revenues and assets as reported in its consolidated financial statements. The Company does not currently maintain a hedging program with respect to its foreign currency exposure, and future exchange rate movements may continue to affect the Company's reported results of operations.

**Supplier and supply chain relationships**

A significant portion of the Company's products — including analytical instruments, environmental monitoring equipment, and BWTS products — are sourced from international suppliers, including Japanese and European manufacturers. The Company's operating results are therefore affected by the availability and pricing of products from these suppliers, the strength of the Company's supplier relationships, and the ability of suppliers to fulfill orders on a timely basis. Disruptions to global supply chains, including those arising from geopolitical tensions, transportation bottlenecks, or raw material shortages, could affect the Company's ability to fulfill customer orders and could result in increased costs or reduced margins. The ongoing U.S.-China trade tensions and associated tariff measures may also indirectly affect the pricing and availability of certain products that the Company sources from international suppliers.

**Macroeconomic and regulatory environment in mainland China**

The Company's operating results are significantly influenced by macroeconomic conditions and the regulatory environment in mainland China, which is both a key market for the Company's products and services and the jurisdiction in which certain of the Company's operating subsidiaries are incorporated. Factors that have affected, and are expected to continue to affect, the Company's operating results in mainland China include: the pace of economic growth and industrial activity; government spending on environmental infrastructure; the enforcement of environmental protection standards; and broader policy developments affecting foreign-invested enterprises operating in mainland China. Any significant deterioration in macroeconomic conditions in mainland China, or a shift in government policy unfavorable to environmental infrastructure investment or foreign-invested enterprises, could have a material adverse effect on the Company's revenues and results of operations.

**Results of Operations**

The following operating and financial review should be read in conjunction with the Consolidated Financial Statements and notes thereto appearing elsewhere in this Annual Report. All financial data referred to in the following discussion has been prepared in accordance with U.S. GAAP.

**Fiscal Year Ended December 31, 2025 Compared to Fiscal Year Ended December 31, 2024**

**Revenue; Gross Profit and Cost of Revenue.** Revenue decreased by US$2,118,000 or 13.8% to US$13,265,000 in Fiscal 2025 from US$15,383,000 in Fiscal 2024. Revenue from trading and manufacturing activities decreased by US$2,165,000 and revenue from engineering activities increased by US$47,000, respectively. The decrease in revenue from trading activities was primarily attributable to lowered sales US products to China following US tariffs and Chinese retaliatory measures.

Gross profit decreased by US$780,000 or 17.5% to US$3,674,000 for Fiscal 2025 as compared to US$4,454,000 for Fiscal 2024. During Fiscal 2025, the Company's cost of revenues was US$9,591,000, or 72.3% of revenues, as compared to US$10,929,000, or 71.0% of revenues, for Fiscal 2024. Cost of revenues expressed as a percentage of revenues increased by 1.3% in Fiscal 2025 as compared to Fiscal 2024. Cost of revenues from trading activities decreased by US$1,773,000 and cost of revenues from engineering activities increased by US$435,000. The overall change was principally attributable to decrease in revenue.

**Selling and Administrative Expenses.** Selling and administrative expenses were US$3,907,000 in Fiscal 2025, a decrease of US$160,000 or 3.9% from US$4,067,000 in Fiscal 2024. The change was principally attributable to controls over expenses.

**Equity in Income of Affiliates.** Equity in income of affiliates was US$334,000 in Fiscal 2025, a decrease of US$64,000, or approximately 16.1%, from US$398,000 in Fiscal 2024. The decrease was primarily attributable to a decline in Blue Sky's revenue resulting from the postponement of certain projects and a decrease in revenue from a BOT project that carries a higher gross profit margin than Blue Sky's other projects, both of which contributed to a reduction in Blue Sky's overall gross profit and net income for the period.

**Interest Income.** Interest income in Fiscal 2025 was US$82,000.00 as compared to US$96,000 in Fiscal 2024. The change was principally attributable to decrease of deposit interest rate.

**Other Income.** Other income was US$14,000 in Fiscal 2025 as compared to US$37,000 in Fiscal 2024. The change was principally attributable to decrease in rental income.

**Income Taxes.** Income tax expense was US$27,000 in Fiscal 2025 as compared to US$72,000 in Fiscal 2024. The change in tax expense was principally attributable to decrease of assessable profit.

**Net Income / (Loss).** Net income attributable to Euro Tech Holdings Company Limited's shareholders was US$157,000 in Fiscal 2025, as compared to US$734,000 in Fiscal 2024, representing a decrease of US$577,000. The decrease was primarily attributable to a decline in revenue from trading activities and a corresponding reduction in gross profit margin during the period.

**Fiscal Year Ended December 31, 2024 Compared to Fiscal Year Ended December 31, 2023**

**Revenue; Gross Profit and Cost of Revenue.** Revenue decreased by US$2,557,000, or 14.3%, to US$15,383,000 in Fiscal 2024 from US$17,940,000 in Fiscal 2023. Revenue from trading and manufacturing activities decreased by US$2,994,000, while revenue from engineering activities increased by US$37,000. The decrease in revenue from trading and manufacturing activities was primarily attributable to a substantial reduction in sales of high-value analytical instruments to the Hong Kong Government. Pact-Yixing's revenues of US$5,834,000 and US$5,797,000 were included in the Company's consolidated revenues in Fiscal 2024 and Fiscal 2023, respectively.

Gross profit increased by US$593,000, or 15.4%, to US$4,454,000 for Fiscal 2024 as compared to US$3,861,000 for Fiscal 2023. During Fiscal 2024, the Company's cost of revenues was US$10,929,000, or 71.0% of revenues, as compared to US$14,079,000, or 78.5% of revenues, for Fiscal 2023. Cost of revenues expressed as a percentage of revenues decreased by 7.5 percentage points in Fiscal 2024 as compared to Fiscal 2023. Cost of revenues from trading and manufacturing activities decreased by US$2,451,000 and cost of revenues from engineering activities decreased by US$699,000. The overall improvement in gross margin was principally attributable to a reduction in sales of high-value analytical instruments with lower gross profit margins and an increase in revenues from BWTS products with higher gross profit margins. Pact-Yixing contributed US$2,205,000 to the Company's gross profit in Fiscal 2024, an increase of US$736,000 from US$1,469,000 in Fiscal 2023, principally due to the increase in revenues from BWTS products at higher gross profit margins.

**Selling and Administrative Expenses.** Selling and administrative expenses were US$4,067,000 in Fiscal 2024, a decrease of US$36,000, or 0.9%, from US$4,103,000 in Fiscal 2023.

**Equity in Income of Affiliates.** Equity in income of affiliates was US$398,000 in Fiscal 2024, a decrease of US$1,529,000 from US$1,927,000 in Fiscal 2023. The decrease was primarily attributable to the non-recurrence of exceptional income recognized in Fiscal 2023 in connection with the disposal of two desulfurization treatment plants under a build-operate-transfer ("BOT") project located in Shanxi, China.

**Interest Income.** Interest income was US$96,000 in Fiscal 2024 as compared to US$37,000 in Fiscal 2023. The increase was principally attributable to higher cash balances held during the year.

**Other Income.** Other income was US$37,000 in Fiscal 2024 as compared to other losses of US$20,000 in Fiscal 2023. The change was principally attributable to foreign exchange losses recognized in Fiscal 2023 that did not recur in Fiscal 2024.

**Income Taxes.** Income tax expense was US$72,000 in Fiscal 2024 as compared to US$45,000 in Fiscal 2023. The increase in tax expense was principally attributable to an increase in assessable profits.

**Net Income.** Net income attributable to Euro Tech Holdings Company Limited's shareholders was US$734,000 in Fiscal 2024 as compared to US$1,828,000 in Fiscal 2023. The decrease was primarily attributable to the non-recurrence of the exceptional increase in equity in income of affiliates recognized in Fiscal 2023 in connection with the disposal of the two desulfurization treatment plants under the BOT project in Shanxi, China, as described above.

**B. LIQUIDITY AND CAPITAL RESOURCES**

The Company has primarily financed its accounts receivable, contract assets, inventories, and capital expenditures — including purchases of property, office furniture and equipment, computers, and calibration equipment — from its own funds. The Company has historically met its cash requirements through cash flows from operations, short-term borrowings, bank lines of credit, and long-term mortgage bank loans. The Company expects that its present cash reserves, cash flows from operations, and existing available bank credit facilities will be sufficient to fund its anticipated capital expenditure requirements, although no assurance can be given in this regard.

Working capital at the end of Fiscal 2025, Fiscal 2024, and Fiscal 2023 was US$4,659,000, US$5,224,000, and US$4,949,000, respectively.

As of December 31, 2025, the Company had US$4,283,000 in cash and cash equivalents, as compared to US$5,805,000 as of December 31, 2024 and US$5,453,000 as of December 31, 2023.

**Operating Activities**

Net cash used in operating activities was US$1,415,000 for the year ended December 31, 2025, as compared to net cash provided by operating activities of US$781,000 for the year ended December 31, 2024 and net cash used in operating activities of US$80,000 for the year ended December 31, 2023.

Net cash used in operating activities for the year ended December 31, 2025 was primarily the result of net income of US$157,000, equity in income of affiliates of US$334,000, amortization of right-of-use assets of US$150,000, an increase in accounts receivable of US$609,000, and an increase in contract assets of US$1,209,000. These amounts were partially offset by a decrease in inventories of US$156,000, an increase in accounts payable of US$445,000 and an increase in long-term operating lease obligations of US$151,000.

Net cash provided by operating activities for the year ended December 31, 2024 was primarily the result of net income of US$734,000, a decrease in accounts receivable of US$1,478,000, a decrease in inventories of US$223,000, non-controlling interests in income of subsidiaries of US$111,000, equity in income of affiliates of US$398,000, and amortization of right-of-use assets of US$132,000. These amounts were partially offset by a decrease in accounts payable of US$1,177,000.

**Investing Activities**

Net cash provided by investing activities was US$314,000 for the year ended December 31, 2025, as compared to US$302,000 for the year ended December 31, 2024 and US$317,000 for the year ended December 31, 2023.

**Financing Activities**

Net cash used in financing activities was US$317,000 for the year ended December 31, 2025, primarily as a result of purchase of treasury stock of US$319,000.

Net cash used in financing activities for the year ended December 31, 2024 was US$778,000, as a result of dividend payments of US$617,000, purchases of treasury stock of US$7,000, and repayments of bank borrowings of US$154,000.

Net cash used in financing activities for the year ended December 31, 2023 was US$82,000, as a result of proceeds from bank borrowings related to trade finance purchases of US$666,000, offset by purchases of treasury stock of US$14,000 and repayments of bank borrowings of US$734,000.

**Cash And Cash Equivalents — Summary**

The Company's cash and cash equivalents decreased from US$5,805,000 at the end of Fiscal 2024 to US$4,283,000 at the end of Fiscal 2025. The principal reason for this decrease was cash used in operating activities.

Cash increased from US$5,453,000 at the end of Fiscal 2023 to US$5,805,000 at the end of Fiscal 2024. The principal reason for the increase in cash was strong operating cash inflows during the year, partially offset by dividend payments of US$617,000.

**Accounts Receivable And Inventories**

The Company's accounts receivable decreased from US$2,864,000 at the end of Fiscal 2023 to US$1,386,000 at the end of Fiscal 2024, and increased to US$1,995,000 at the end of Fiscal 2025. Accounts receivable are expected to be collected under normal commercial trading terms.

The Company's inventories decreased from US$723,000 at the end of Fiscal 2023 to US$500,000 at the end of Fiscal 2024, and decreased to US$344,000 at the end of Fiscal 2025.

**Banking Facilities** 

As of December 31, 2025, the Company had various banking facilities available for overdraft, import and export credits, and foreign exchange contracts, from which the Company could access up to US$897,000. As of December 31, 2024, such available credit facilities amounted to US$897,000. These credit facilities were obtained on the conditions that, among other things, the Company pledge bank deposits of US$897,000 as at December 31, 2025, not create any charge or lien on its other assets in favor of third parties without the relevant bank's consent, and maintain a minimum level of net worth.

**Capital Expenditure**

The Company's capital expenditures were US$7,000, US$5,000, and US$5,000 in Fiscal 2025, Fiscal 2024, and Fiscal 2023, respectively. Capital expenditures during each of these fiscal years were incurred primarily in connection with the purchase of office equipment, furniture, and fixtures. The Company continues to invest in the development of new products. If new product developments are undertaken, the Company may incur significantly larger capital expenditures in future periods. The Company presently intends to fund any such expenditures from existing cash reserves, cash flows from operations, and available bank credit facilities, although no assurance can be given in this regard.

**Goodwill Impairment Assessment**

For the Company's Fiscal 2025 annual impairment assessment, the Company performed a qualitative assessment using information as of December 31, 2025. Under current accounting guidance, the Company is permitted to first assess qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount, as a basis for determining whether it is necessary to perform a quantitative goodwill impairment test. Based on this qualitative assessment, the Company determined that there were no factors indicating the need to perform a quantitative goodwill impairment test, and concluded that it is more likely than not that the fair value of the Company's reporting units exceeds their respective carrying values. Accordingly, no impairment to goodwill was recognized in Fiscal 2025.

For the Company's Fiscal 2024 annual impairment assessment, the Company performed a qualitative assessment using information as of December 31, 2024 and reached the same conclusion — that it is more likely than not that the fair value of the Company's reporting units exceeds their respective carrying values, and that no quantitative goodwill impairment test was necessary. Accordingly, no impairment to goodwill was recognized in Fiscal 2024.

**Anticipated Future Resources and Uses of Cash**

The Company has historically funded its working capital, capital expenditure, investing, and expansion needs from cash flows from operations, available bank credit facilities, and proceeds from the issuance of ordinary shares, and expects to continue funding these requirements from the same sources. The Company may also use its funds to form strategic alliances with third parties, invest in product research and development, expand its sales offices, or seek to acquire new products. The Company expects that its present cash reserves, cash flows from operations, and existing available bank credit facilities will be sufficient to fund its anticipated future cash requirements, although no assurance can be given in this regard.

**Holding Company Structure and Restrictions on Cash Transfers**

Euro Tech Holdings Company Limited is a holding company with no operations of its own. The Company conducts its operations in Hong Kong and mainland China primarily through its subsidiaries and operating affiliates.

Under the Company's current corporate structure, the BVI holding company holds 100% of the issued share capital of Euro Tech Global, a company incorporated in Singapore. Euro Tech Global in turn holds 100% of the issued share capital of Far East, a company incorporated in Hong Kong. Far East holds the Company's PRC subsidiaries and operating affiliates. The BVI holding company relies on dividend payments upstream through this chain of subsidiaries — from the PRC operating subsidiaries to Far East, from Far East to Euro Tech Global, and from Euro Tech Global to the BVI holding company — to fund its cash and financing requirements.

Under applicable PRC laws and regulations, the Company's PRC subsidiaries are permitted to pay dividends only out of their accumulated profits, if any, as determined in accordance with PRC accounting standards and regulations. In addition, the Company's PRC subsidiaries are required to allocate at least 10% of their accumulated after-tax profits each year to fund statutory reserves, until the cumulative amount of such reserves reaches 50% of the registered capital of the relevant entity. Statutory reserves are not distributable as cash dividends except in the event of liquidation. No dividends were distributed from the Company's PRC subsidiaries to Far East during Fiscal 2023, Fiscal 2024, or Fiscal 2025.

These restrictions on the ability of the Company's PRC subsidiaries to distribute profits upstream through the holding company structure may limit the Company's ability to access cash generated by its PRC operations and could adversely affect the Company's liquidity and its ability to pay dividends to its shareholders.

**Off-Balance Sheet Arrangements** 

The Company has not entered into any financial guarantees or other commitments to guarantee the payment obligations of any third parties. The Company does not have any retained or contingent interest in assets transferred to an unconsolidated entity that serves as credit, liquidity, or market risk support to such entity. The Company has no obligations under any derivative instrument and no obligations arising out of a variable interest in any unconsolidated entity that provides financing, liquidity, market risk, or credit support to the Company or that engages in leasing, hedging, or research and development services with the Company.

**C. RESEARCH AND DEVELOPMENT, PATENTS AND LICENSES, ETC.**

The Company did not incur any separately classified research and development expenses in Fiscal 2023, Fiscal 2024, or Fiscal 2025. The Company has, however, invested internal resources in the ongoing development of its BWTS product line and ballast water port solution system, including the development activities conducted by Pact-Yixing described under "Item 4.B — Business Overview — Our Growth Strategy."

The Company holds 5 utility model patents and has 1 invention patent application pending in mainland China in connection with its ballast water port solution system, and holds 7 registered patents and 1 patent application pending in mainland China in connection with its other products. The costs associated with obtaining and maintaining these patents have not been material. The Company also holds various distribution licenses and authorization agreements with its principal suppliers, as described under "Item 4.B — Business Overview — Sources of Supply." No material license fees were paid by the Company in connection with these arrangements during the periods covered by this Annual Report.

**D. TREND INFORMATION** 

**Regulatory Drivers**

The ongoing tightening of environmental regulations governing water pollution, marine pollution, and ship-related emissions in mainland China and internationally continues to present opportunities for the Company's water and wastewater treatment engineering and distribution businesses. As described in greater detail under "Item 4.B — Business Overview — Regulatory Environment," the PRC regulatory framework governing water pollution from inland river vessels has been progressively strengthened, and the Amendment to the Marine Environmental Protection Law, effective January 1, 2024, has further strengthened the supervision and management of marine environmental pollution from ships operating in port areas. The Company anticipates that these regulatory developments will generate increasing demand from ports, shipyards, and industrial operators to implement compliant water and wastewater treatment solutions.

**ESG and Sustainability Trends**

An increasing number of companies in mainland China and internationally have adopted internal Environmental, Social and Governance ("ESG") goals or face external ESG requirements from investors, regulators, or customers. The Company anticipates that this trend will increase demand among its existing and potential customers for environmental compliance solutions, including water and wastewater treatment systems and environmental monitoring products of the type the Company distributes and installs. As environmental regulations continue to be promulgated and enforced and as ESG considerations become more prominent in corporate decision-making, the Company expects that customers will increase their budgets for improving and upgrading their environmental protection infrastructure. The Company believes these trends will present increasing opportunities across both of its operating segments.

In mainland China specifically, the continued implementation of the national "dual carbon" policy — under which China has committed to reaching peak carbon emissions before 2030 and achieving carbon neutrality before 2060 — is expected to drive sustained government and private sector investment in environmental infrastructure, including water treatment, pollution control, and clean energy projects. The Company believes its products and services are well positioned to benefit from this policy-driven investment trend.

**Ballast Water Treatment System Demand**

The global regulatory framework governing ballast water management continues to evolve, with the IMO Ballast Water Management Convention having entered into force and enforcement activity continuing to intensify across key maritime jurisdictions. The Company has observed strong and growing demand for BWTS products from the energy-related shipping industry in the Middle East and from petrochemical port operators in mainland China, and anticipates that this demand will continue as shipowners and operators seek to achieve and maintain regulatory compliance.

The Company notes, however, that the ongoing geopolitical instability in the Middle East — including regional conflicts and disruptions to maritime trade routes — introduces uncertainty into the outlook for BWTS demand from that region. A material deterioration in maritime shipping activity in the Middle East, or a disruption to the Company's ability to serve customers in that region, could adversely affect the Company's BWTS revenues. The Company continues to monitor geopolitical developments in the Middle East and their potential impact on its business.

**U.S.-China Trade Tensions and Tariff Environment**

The escalation of U.S.-China trade tensions during 2025 — including the announcement of significant additional tariff measures by the United States government targeting goods imported from mainland China — represents a material trend that the Company is actively monitoring. While the Company does not derive revenues directly from the United States market, U.S.-China trade friction may affect the Company's business in a number of indirect ways, including:

· affecting the broader economic environment and business confidence in mainland China and Hong Kong, which could reduce customer capital expenditure on environmental infrastructure;

· affecting the pricing and availability of products that the Company sources from international suppliers, some of which may themselves be affected by trade restrictions or supply chain realignments; and

· creating uncertainty for Chinese subsidiaries of foreign companies — which represent an important segment of the Company's customer base for wastewater treatment systems — some of which may delay, suspend, or reconsider their business operations in mainland China in response to the trade environment.

The Company is unable to predict the ultimate scope, duration, or further escalation of current U.S.-China trade tensions or their ultimate effect on the Company's business, financial condition, and results of operations.

**Renewable Energy and New Market Opportunities**

The Company has observed a growing trend toward the use of renewable energy sources — including green hydrogen and biofuels — in the transportation sector, including for ship vessels and port operations. The Company believes that its technical expertise in water treatment is relevant to the production processes for both green hydrogen and biofuels, as water is a fundamental raw material in these production processes and water purification is an important component thereof. Accordingly, the Company believes it may be in a position to add value to the supply chain of renewable energy producers as this market develops.

In addition, the Company has observed that certain industries — including the liquefied natural gas ("LNG") industry — use pure or demineralized water as produced water in their internal production processes. As the Company's experience and capabilities in water treatment continue to develop, the Company believes it may have opportunities to serve customers in the LNG industry and other sectors in which water quality is a fundamental input to the production process.

The Company also intends to explore opportunities to work with new strategic partners to provide customized water treatment solutions for customers in sectors where water is a fundamental raw material or a key element of the production process.

**Digital Transformation and Smart Environmental Monitoring**

The Company has observed an increasing trend among industrial operators and municipal authorities in mainland China and Hong Kong toward the adoption of digitally integrated environmental monitoring and management systems, including real-time water quality monitoring, remote sensing, and data-driven compliance reporting platforms. This trend is driven in part by PRC regulatory requirements for environmental monitoring data to be reported electronically to government authorities in real time, and in part by broader industry adoption of digital transformation and Industry 4.0 technologies. The Company believes that this trend presents opportunities to expand its distribution of advanced analytical instruments, analyzers, and environmental monitoring equipment — products that the Company has historically distributed through its trading and manufacturing segment — and to develop value-added service offerings around these products. The Company is monitoring this trend and evaluating opportunities to enhance its product and service offerings in response.

**Competitive Trends**

The Company anticipates continued growth in the number of distributors and manufacturers of water treatment products competing in the markets in which it operates, including increasing competition from domestic PRC manufacturers of BWTS and wastewater treatment equipment, which may exert downward pressure on selling prices and margins in these product categories. The Company also expects to incur additional expenses in connection with the design and development of new products, and there can be no assurance that such cost increases will be offset by corresponding increases in revenues in the near term.

The Company believes that its long-standing relationships with established international suppliers, its technical expertise, and its track record of delivering complex engineering projects differentiate it from lower-cost competitors in its key markets. However, there can be no assurance that the Company will be able to maintain these competitive advantages in the face of increasing competition.

**General**

Other than as disclosed in this section and elsewhere in this Annual Report, the Company is not aware of any trends, uncertainties, demands, commitments, or events for Fiscal 2025 that are reasonably likely to have a material adverse effect on the Company's net revenues, income, profitability, liquidity, or capital resources, or that would cause the financial information disclosed herein to be not necessarily indicative of future operating results or financial condition.

**E. CRITICAL ACCOUNTING ESTIMATES** 

The preparation of the accompanying consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and judgments that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the consolidated financial statements, and the reported amounts of revenues and expenses during the reporting period. Certain accounting estimates require a higher degree of judgment than others in their application, including the recognition of revenue and earnings from engineering contracts satisfied over time, the valuation of goodwill, and the measurement of contract assets and contract liabilities. Management continually evaluates its estimates and judgments based on available information and experience; however, actual results could differ from these estimates.

**1. Revenue Recognition**

The Company recognizes revenue in accordance with Accounting Standards Codification ("ASC") Topic 606, Revenue from Contracts with Customers ("ASC 606"), as amended by Accounting Standards Update ("ASU") 2014-09.

The core principle of ASC 606 is that revenue should be recognized in a manner that depicts the transfer of promised goods or services to customers in an amount that reflects the consideration to which the Company expects to be entitled in exchange for those goods or services. The Company applies the following five-step model to achieve that core principle:

---

| |
|:---|
| Step 1: Identify the contract with the customer; |
| Step 2: Identify the performance obligations in the contract; |
| Step 3: Determine the transaction price; |
| Step 4: Allocate the transaction price to the performance obligations in the contract; and |
| Step 5: Recognize revenue when, or as, the Company satisfies a performance obligation. |

---

The Company's revenues are derived from both short-term and long-term contracts with customers in the engineering segment, as well as short-term contracts with customers in the trading and manufacturing segment. The accounting treatment applicable to each type of contract is described below.

**Performance Obligations Satisfied Over Time — Engineering Services**

Recognition of Performance Obligations

A performance obligation is a promise in a contract to transfer a distinct good or service to the customer and is the unit of account under ASC 606. The transaction price of a contract is allocated to each distinct performance obligation and recognized as revenue when, or as, that performance obligation is satisfied.

Engineering service projects typically span from several days to over five years. The majority of the Company's long-term engineering contracts contain a single performance obligation, as the promise to transfer individual goods or services is not separately identifiable from other promises in the contract and is therefore not distinct. Some contracts contain multiple performance obligations, most commonly where the contract covers multiple phases of the project life cycle. Revenue is recognized as performance obligations are satisfied over time, by reference to the progress toward complete satisfaction of each performance obligation.

Where the Company determines that reference to progress certificates issued by customers — with such additional adjustments as may be necessary — appropriately depicts the Company's performance in transferring control of goods or services to customers for individual projects, the Company recognizes revenue over time in accordance with the output method for measuring progress. Under the output method, revenue recognition is based on the stage of completion of the contract, provided that the stage of completion and the gross billing value of the contracting work can be measured reliably. The stage of completion of a contract is determined by reference to billing milestones or stages of work certified by the customer. Invoices are generally billed upon fulfillment of measurable performance obligations. The Company evaluates progress toward completion of each performance obligation at each phase of the contract and bills the customer in accordance with the contract price.

|:---|
| 73 |
| *[**Table of Contents**](#TOC)* |

---

Remaining Performance Obligations

Remaining performance obligations ("RPOs") represent the amount of revenues the Company expects to recognize in future periods from its contract commitments on projects in progress, and are referred to herein as "Backlog." Backlog includes the full expected revenue values for subsidiaries that the Company consolidates. Backlog may not be indicative of future operating results, and projects included in Backlog may be canceled, modified, or otherwise altered by customers.

Variable Consideration

Contract modifications through change orders, claims, and incentives are routine in the performance of the Company's engineering contracts and arise to account for changes in contract specifications or requirements. In most instances, contract modifications are not distinct from the existing contract, due to the significant integration services provided under the contract, and are therefore accounted for as modifications of the existing contract and performance obligation. Either the Company or its customers may initiate change orders, which may include changes in specifications or designs, manner of performance, facilities, equipment, materials, sites, or the period of completion of the work. Change orders that are unapproved as to both price and scope are evaluated as claims. Claims are amounts in excess of approved contract prices that the Company seeks to collect from its customers or others for customer-caused delays, errors in specifications and designs, contract terminations, change orders that are in dispute or unapproved as to both scope and price, or other causes of unanticipated additional contract costs.

In the event that a customer requests a change order — such as an upgrade of specifications, materials, or additional scope of work — prior to the completion of the project, the Company will negotiate and execute a supplemental agreement with the customer, subject to mutual agreement. The supplemental agreement contains its own terms and conditions for variable consideration and is generally integrated with the original master contract. Change orders typically result in an increase in the total billing to the customer and only rarely result in a reduction in the total contract value.

The effect of variable consideration on the transaction price of a performance obligation is recognized as an adjustment to revenue on a cumulative catch-up basis. To the extent that unapproved change orders or claims reflected in the transaction price — or excluded from the transaction price in the case of liquidated damages — are not resolved in the Company's favor, or to the extent that incentives reflected in the transaction price are not earned, there could be reductions in, or reversals of, previously recognized revenue.

**Performance Obligations Satisfied at a Point in Time — Trading and Manufacturing**

Revenue from the Company's trading and manufacturing contracts is recognized at a point in time. Revenue is recognized when control of the products has transferred to the customer, which occurs upon delivery of the products to the customer's designated point of receipt.

**2. Goodwill**

Goodwill is not amortized. The Company performs either a qualitative or quantitative assessment to review goodwill for impairment on an annual basis. This assessment is performed at the beginning of the fourth fiscal quarter, or when circumstances change that would indicate that impairment may have occurred, such as a significant adverse change in the business climate or a decision to sell a business unit.

A qualitative assessment considers financial, industry, segment, and macroeconomic factors. If the qualitative assessment indicates that impairment is more likely than not, a quantitative assessment is performed to determine whether impairment exists. The quantitative assessment begins with a comparison of the fair value of the reporting unit with its carrying value. If the carrying amount of the reporting unit exceeds its fair value, an impairment loss is recognized in an amount equal to that excess, limited to the total amount of goodwill allocated to that reporting unit.

**3. Accounts Receivable and Allowance for Credit Losses**

The Company does not charge interest to its customers and carries its customer receivables at their face amounts, net of expected credit losses. Consistent with industry practice, all accounts receivable are classified as current assets.

The Company grants trade credit to its customers on a non-collateralized basis and is therefore subject to credit risk related to changes in its customers' financial condition and overall economic activity. The Company evaluates the adequacy of its allowance for credit losses by analyzing specific account balances, historical credit loss experience, customer creditworthiness, current economic trends, and changes in customer payment terms. Customer balances that are determined to be uncollectible are written off against the allowance for credit losses.

**4. Inventories**

Inventories are measured using the first-in, first-out method and are stated at the lower of cost or net realizable value. The cost of finished goods comprises direct materials, direct production costs, and an allocated portion of production overhead costs based on normal operating capacity. Allowances are made for obsolete, slow-moving, or defective items where appropriate.

**Stock Option Plans**

2019 Stock Option and Incentive Plan

In April 2019, the Board of Directors approved the adoption of the 2019 Stock Option and Incentive Plan (the "Plan"), subsequently approved by the Company's shareholders. The Plan provides for the granting of options to purchase up to 500,000 ordinary shares (as adjusted in January, 2022) to officers, directors, and key employees. The Plan is administered by the Board of Directors or a committee appointed by the Board (the "Committee"). No option may be exercised more than ten years from the date of grant. The exercise price per ordinary share payable upon exercise of an option must not be less than 100% of the fair market value of an ordinary share on the date of grant, determined by reference to the average closing price of the ordinary shares for the ten consecutive trading days immediately preceding the date of grant.

Option Grants

In Fiscal 2019, the Company granted options to its officers, directors, and employees to purchase up to 51,000 ordinary shares at an exercise price of US$2.60 per share. These options became exercisable on January 1, 2022 and will expire on April 18, 2029. The fair value of these options was estimated at US$2.324 per share using the Binomial pricing model.

In Fiscal 2022, the Company granted options to its officers, directors, and employees to purchase up to 80,000 ordinary shares at an exercise price of US$2.80 per share. These options became exercisable on April 1, 2024 and will expire on April 18, 2029. The fair value of these options was estimated at US$1.3055 per share using the Binomial pricing model. Also during Fiscal 2022, 41,250 options were cancelled following the departure of the relevant employees from the Company.

No options were granted during Fiscal 2023, Fiscal 2024, and Fiscal 2025.

The Company recognizes stock-based compensation expense in accordance with ASC Topic 718, Compensation — Stock Compensation, which requires that the fair value of stock-based compensation awards, including employee stock options, be recognized as expense over the relevant service period.

**Issuance of Bonus Shares**

We issued bonus shares on January 21, 2022 to shareholders of record as of January 7, 2022; such shareholders received one (1) ordinary share for every two (2) ordinary shares held. All issuances resulting in a fractional share will be rounded down to the next whole share. We did not issue any bonus shares at any other time.

**C. BOARD PRACTICES**

**Terms of Directors and Executive Officers**

The Company's Board of Directors consisted of seven directors during Fiscal 2025. The term of each director expires upon the election and qualification of his or her successor at the next annual meeting of the Company's shareholders, anticipated to be held in November 2026. The Company's directors were re-elected at the annual meeting of shareholders held in November 2025. The service agreements between the Company and its directors do not provide for any benefits upon termination of their services.

The Company's executive officers are elected by and serve at the discretion of the Board of Directors. Each executive officer holds office until his or her successor is duly elected and qualified, provided that any officer elected or appointed by the Board of Directors may be removed at any time, with or without cause, by resolution of the Board of Directors. Any vacancy occurring in any office of the Company may be filled by resolution of the Board of Directors.

The Board of Directors held 5 meetings during Fiscal 2025.

**Board Committee**

Audit Committee

The Board has a standing Audit Committee to assist the Board in carrying out its oversight responsibilities. The Audit Committee operates pursuant to a written charter approved by the Board of Directors. The Chair of the Audit Committee determines the agenda for each Audit Committee meeting, and Audit Committee members receive relevant materials in advance of each meeting to allow adequate preparation.

**Dividend Policy** 

The payment of future cash dividends, if any, is within the discretion of the Board of Directors and will depend upon the Company's earnings, capital requirements, financial condition, and such other factors as the Board of Directors may deem relevant. The Company did not declare any dividend in Fiscal 2023, 2024 and 2025, except on May 28, 2024, the Company declared a dividend in the aggregate amount of US$617,303.92, paid to all holders of record of the Company's ordinary shares as of June 13, 2024. The Board of Directors does not presently intend to declare any cash dividends in the foreseeable future and instead intends to retain all earnings, if any, for use in the operations of the Company and its subsidiaries.

Euro Tech Holdings Company Limited is a holding company incorporated in the BVI with no operations of its own. The Company relies on dividends from its subsidiaries and affiliates in mainland China, Hong Kong, Singapore, and the BVI to fund its cash requirements, including any future payment of dividends to shareholders. The ability of the Company's subsidiaries in each of these jurisdictions to pay dividends to the Company may be restricted by applicable laws and regulations in their respective jurisdictions of incorporation or operation, as described under "Item 5.B — Liquidity and Capital Resources — Holding Company Structure and Restrictions on Cash Transfers."

**B. MEMORANDUM AND ARTICLES OF ASSOCIATION**

**Corporate History and Re-registration**

On January 1, 2005, the BVI Business Companies Act (as amended, the "BC Act") came into force with the objective of replacing the then-applicable International Business Companies Act (the "IBC Act") over a two-year transitional period. The Company was originally incorporated under the IBC Act. On January 1, 2007, the Company was automatically re-registered under the BC Act as a BVI Business Company. Companies that were automatically re-registered on January 1, 2007 were not required to submit a new memorandum and articles of association, and certain key provisions of the IBC Act were carried forward into the BC Act through transitional provisions (the "Transitional Provisions"). The Transitional Provisions preserved well-established concepts from the IBC Act — such as "authorized capital," "capital accounts," and "surplus accounts" — until such time as the relevant company elected to adopt and register a new memorandum and articles of association fully conforming with the BC Act.

In November 2011 and January 2012, the Company filed an Amended and Restated Memorandum and Articles of Association with the Registry of Corporate Affairs of the BVI Financial Services Commission, which became effective upon filing on November 29, 2011 and January 30, 2012, respectively. The amendments served, among other purposes, to: (i) disapply the Transitional Provisions; and (ii) remove the IBC Act concepts of authorized capital, capital accounts, and surplus accounts from the Company's constitutional documents, thereby eliminating a layer of requirements that would otherwise apply to share splits, reverse share splits, redemptions, and dividends. The Company's accounting treatment of share capital was not affected by these amendments. A summary of the amendments is set out in the Company's Forms 6-K filed with the SEC on November 30, 2011 and February 6, 2012, which are incorporated herein by reference.

The following is a summary of certain terms of the Company's Amended and Restated Memorandum and Articles of Association (the "Memorandum and Articles") and the BC Act relating to the Company's securities. This summary does not purport to be complete and is qualified in its entirety by reference to the BC Act and the Memorandum and Articles, copies of which have been filed with the SEC.

**Ordinary Shares**

Holders of the Company's ordinary shares are entitled to one vote per share on all matters to be voted upon by shareholders, including the election of directors. Holders of ordinary shares do not have cumulative voting rights in the election of directors. All ordinary shares rank equally with respect to liquidation and dividend rights. In the event of a liquidation of the Company, all assets available for distribution to holders of ordinary shares are distributable among them pro rata in accordance with their respective shareholdings. All outstanding ordinary shares of the Company are duly authorized, validly issued, fully paid, and non-assessable.

**Amendment of Memorandum and Articles of Association**

Pursuant to the Company's Memorandum and Articles and applicable BVI law, the Company's Memorandum and Articles may be amended by a resolution of the Board of Directors without shareholder approval. This includes amendments to increase or reduce the Company's authorized share capital or to change the par value of its shares. The ability of the Board of Directors to amend the Memorandum and Articles without shareholder approval could have the effect of delaying, deterring, or preventing a change of control of the Company without further action by shareholders, including in connection with a tender offer to purchase ordinary shares at a premium to the then-current market price.

**Minority Shareholder Protections**

Under United States law, majority and controlling shareholders generally owe fiduciary duties to minority shareholders, and actions by controlling shareholders that are manifestly unreasonable may be declared null and void. BVI law does not afford minority shareholders the same breadth of protections available under the laws of United States jurisdictions in all circumstances. In particular, BVI law does not permit a shareholder of a BVI company to bring a derivative action — that is, an action brought in the name of and for the benefit of the Company — and the circumstances in which other forms of shareholder action may be available under BVI law may result in the rights of shareholders of a BVI company being more limited than those of shareholders of a United States company.

**Preferred Shares**

The Board of Directors may, without further shareholder approval, issue preferred shares in one or more series and may, with respect to each such series, establish the designation and number of shares to be issued and the relative rights and preferences of that series, including provisions regarding voting powers, redemption rights, dividend rights, rights upon liquidation, and conversion rights. The issuance of preferred shares could adversely affect the rights of holders of ordinary shares by, among other things, establishing preferential dividend, liquidation, and voting rights. The Company has not issued any preferred shares and has no present intention to do so. The issuance of preferred shares could discourage or defeat efforts to acquire control of the Company through the acquisition of ordinary shares.

**Share Register and Transfer**

The Company maintains a share register at its registered office in the BVI. The Company's BVI registered number is 200960. The objects of the Company are to engage in any act or activity that is not prohibited under BVI law. Under the Memorandum and Articles, the Company is not required to treat the holder of a registered share as a shareholder until that person's name has been entered in the share register.

Holders of ordinary shares are entitled to one vote per ordinary share held of record. The voting powers, if any, of holders of preferred shares shall be as set out in the resolution of the Board of Directors providing for the issuance of the relevant series of preferred shares.

**Shareholders' Meetings**

The Board of Directors may convene meetings of shareholders at such times and in such manner and at such places within or outside the BVI as the directors consider necessary or desirable. Upon the written request of shareholders holding 10% or more of the outstanding voting shares of the Company, the directors must convene a meeting of shareholders.

A shareholder may participate in a meeting of shareholders by telephone or other electronic means, provided that all shareholders participating in the meeting are able to hear each other.

A meeting of shareholders is duly constituted if, at the commencement of the meeting, shareholders holding not less than 50% of the votes attaching to the shares or class or series of shares entitled to vote on the resolutions to be considered at the meeting are present in person or by proxy. If a quorum is not present, the meeting shall, if convened upon the requisition of shareholders, be dissolved; in any other case, it shall stand adjourned to the next business day at the same time and place, or to such other time and place as the directors may determine. If at the adjourned meeting shareholders holding not less than one-third of the votes attaching to the shares or each class or series of shares entitled to vote on the resolutions to be considered are present in person or by proxy, those present shall constitute a quorum; otherwise the meeting shall be dissolved.

Any action that may be taken by shareholders at a meeting may also be taken by a resolution consented to in writing or by electronic communication by shareholders holding a majority, or such greater number, of the shares entitled to vote as may be required, without the need for prior notice. If the resolution is not consented to by all shareholders entitled to vote, a copy of the resolution shall be sent to all non-consenting shareholders.

**Pre-emptive Rights**

Holders of ordinary shares and preferred shares are not entitled to any pre-emptive or similar rights in respect of any issuance of shares by the Company.

**Conflicts of Interest**

No agreement or transaction between the Company and one or more of its directors, or any person in which any director has a financial interest or to whom any director is related (including as a director of that other person), is void or voidable solely by reason of that relationship or interest, or solely because the relevant director is present at the meeting of directors or committee of directors that approves the agreement or transaction, or because that director's vote or consent is counted for that purpose, provided that the material facts of each director's interest in the agreement or transaction and his or her interest in or relationship to any other party to the agreement or transaction are disclosed in good faith or are known to the other directors. A director who has an interest in any matter to be considered at a meeting of directors or shareholders may be counted for the purpose of determining whether the meeting is duly constituted.

**Purchase and Redemption of Shares**

No purchase, redemption, or other acquisition of the Company's shares may be made unless the directors determine that, immediately after such purchase, redemption, or acquisition: (i) the Company will be able to satisfy its liabilities as they become due in the ordinary course of business; and (ii) the realizable value of the Company's assets will not be less than the sum of its total liabilities (other than deferred taxes) as shown in the books of account, together with its capital. In the absence of fraud, the determination of the directors as to the realizable value of the Company's assets is conclusive, unless a question of law is involved.

**Duration, Liquidation, and Merger**

The Company shall continue in existence until wound up and dissolved by a resolution of shareholders or pursuant to applicable insolvency or liquidation legislation in force in the BVI. Under BVI law, the Company may merge with another company — including a parent company or subsidiary — incorporated in the BVI or in a jurisdiction outside the BVI whose laws permit such a merger. Any merger must be authorized by the Board of Directors and approved by the shareholders of the Company.

**Board of Directors**

The business and affairs of the Company are managed by the Board of Directors, which may exercise all powers of the Company that are not reserved to the shareholders by BVI law or by the Memorandum and Articles.

**C. MATERIAL CONTRACTS** 

During Fiscal 2024 and Fiscal 2025, we did not enter into any material contracts, other than contracts entered into in the ordinary course of business and other than those described in "Item 4. Information on the Company" and "Item 7. Major Shareholders and Related Party Transactions – B. Related Party Transactions" or elsewhere in this Annual Report on Form 20-F.

**D. EXCHANGE CONTROLS**

**British Virgin Islands**

There are no BVI laws that impose exchange controls on the Company or that affect the payment of dividends, interest, or other payments to non-resident holders of the Company's securities. BVI law and the Company's Memorandum and Articles of Association impose no limitations on the right of non-resident or foreign owners to hold or vote the Company's ordinary shares.

**Singapore**

There are no exchange control restrictions in Singapore that restrict the Company's ability, through Euro Tech Global Pte. Limited, to pay dividends or make other payments to non-resident holders of the Company's securities. Singapore does not currently operate a foreign exchange control regime, and there are no Singapore laws that impose limitations on the right of non-resident or foreign owners to hold or vote the Company's ordinary shares.

**Hong Kong**

There are no exchange control restrictions on the payment of dividends on the Company's ordinary shares or on the conduct of the Company's operations in Hong Kong, where the Company's principal executive offices are located.

**Mainland China**

The PRC government maintains a unified exchange rate system and a comprehensive system of foreign exchange controls administered primarily by the State Administration of Foreign Exchange ("SAFE"). The Renminbi is not freely convertible into foreign currencies for capital account transactions. Cross-border transfers of funds — including the remittance of dividends, profits, and other distributions from the Company's PRC subsidiaries to entities outside mainland China — are subject to PRC regulations governing foreign exchange, which require, among other things, that such transfers be processed through banks authorized to conduct foreign exchange business and comply with applicable SAFE registration and approval requirements.

Under applicable PRC regulations, the Company's PRC subsidiaries may only pay dividends out of their accumulated after-tax profits as determined in accordance with PRC accounting standards and regulations, and are required to set aside a portion of such profits into statutory reserve funds before any dividend distribution may be made. As a result, the ability of the Company's PRC subsidiaries to remit funds to the Company's Hong Kong and Singapore intermediate holding companies — and ultimately to the BVI holding company — may be subject to restrictions and approval requirements under PRC foreign exchange control regulations.

The foregoing description of PRC exchange controls is based on laws and regulations currently in effect and is subject to change. Any future tightening of PRC foreign exchange controls could materially and adversely affect the Company's ability to fund its operations, pay dividends to shareholders, or otherwise transfer funds within its corporate group.

 **E. TAXATION**

The following summary of the material BVI, Singapore, Hong Kong, mainland China and United States federal income tax consequences of an investment in the Company's ordinary shares is based upon laws and relevant interpretations thereof in effect as of the date of this Annual Report, all of which are subject to change. This summary does not address all possible tax consequences relating to an investment in the Company's ordinary shares, such as the tax consequences under state, local, and other tax laws. Prospective investors are urged to consult their own tax advisors regarding the tax consequences of an investment in the Company's ordinary shares in light of their particular circumstances.

**British Virgin Islands** 

The Company and Pact Asia Pacific Limited are exempted from taxation in the BVI under applicable BVI law.

**Singapore**

The Company's subsidiaries incorporated in Singapore are subject to Singapore corporate income tax at a rate of 17%.

**Hong Kong**

The Company's Hong Kong subsidiary, Far East, is subject to Hong Kong profits tax on its assessable profits. Hong Kong profits tax is levied at a two-tier rate: 8.25% on the first HK$2,000,000 (approximately US$256,000) of assessable profits and 16.5% on assessable profits in excess of that threshold. Assessable profits are computed on the basis of income for financial reporting purposes, adjusted for items that are not assessable or not deductible for profits tax purposes.

**Mainland China** 

**Enterprise Income Tax**

The Company's subsidiaries in mainland China are subject to PRC Enterprise Income Tax ("EIT") under the PRC Enterprise Income Tax Law and its implementing regulations. The standard EIT rate applicable to the Company's PRC subsidiaries is 25%.

Euro Tech Trading (Shanghai) Limited ("ETTS"), a subsidiary of Far East, is subject to EIT at the standard rate of 25%, after offsetting any available losses carried forward. As of December 31, 2025, ETTS had an assessable loss carried forward of US$10,000, as agreed with the local tax authority, available to offset future taxable profits. Such losses will expire in 5 years from the year in which they arose. ETTS ceased its active business operations in 2021.

Shanghai Euro Tech Limited ("SET"), a subsidiary of Far East, was subject to EIT at the standard rate of 25% prior to its re-registration in October, 2024.

Yixing Pact Environmental Technology Co. Ltd. ("Yixing") is subject to EIT at the standard rate of 25%, after offsetting any available losses carried forward. As of December 31, 2025, Pact-Yixing had an assessable loss carried forward of US$662,000, as agreed with the local tax authority, available to offset future taxable profits. Such losses will expire five years from the year in which they arose.

Withholding Tax on Dividends

Under the PRC Enterprise Income Tax Law and its implementation rules, profits earned by the Company's PRC subsidiaries on or after January 1, 2008 and distributed to a foreign holding company are subject to a withholding tax at a rate of 10%, unless reduced by an applicable tax treaty. Aggregate undistributed earnings of Far East's PRC subsidiaries that are available for distribution to Far East were approximately US$0.6 million on December 31, 2025. The Company intends to reinvest these earnings and accordingly has not recognized any deferred tax liability for the PRC withholding taxes that would be payable upon their distribution to Far East. Distributions made out of earnings accumulated prior to January 1, 2008 are not subject to this withholding tax.

Reconciliation Of Statutory and Effective Tax Rates

The following table sets forth the items comprising the difference between income taxes computed at the applicable Hong Kong profits tax and PRC EIT statutory rates and the Company's effective income tax rates for Fiscal 2025, Fiscal 2024, and Fiscal 2023:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) Statutory reserve fund.

The Company's PRC subsidiaries are required to allocate at least 10% of their annual after-tax net income to the statutory reserve fund until the cumulative balance of that fund reaches 50% of the relevant subsidiary's registered capital.

Under applicable PRC laws and regulations, the Company's PRC subsidiaries are restricted in their ability to transfer certain net assets in the form of dividend payments, loans, or advances.

This discussion applies only to U.S. Holders (as defined below) that hold the ordinary shares as capital assets within the meaning of Section 1221 of the Internal Revenue Code of 1986, as amended (the "Code"). This discussion is general in nature and does not address all aspects of U.S. federal income taxation that may be relevant to particular investors in light of their individual circumstances.

This discussion is based on the Code, Treasury Regulations promulgated thereunder, and administrative and judicial interpretations thereof, all as in effect as of the date of this Annual Report, all of which are subject to change, possibly with retroactive effect, or to differing interpretation. This discussion does not address U.S. state or local tax considerations, non-U.S. tax considerations, or any U.S. federal estate, gift, Medicare contribution tax applicable to net investment income of certain non-corporate U.S. Holders (as defined below), or alternative minimum tax.

For purposes of this discussion, a "U.S. Holder" is a beneficial owner of ordinary shares that is, for U.S. federal income tax purposes: (a) a citizen or resident of the United States; (b) a corporation or other entity taxable as a corporation created or organized in or under the laws of the United States, any state thereof, or the District of Columbia; (c) an estate the income of which is subject to U.S. federal income taxation, regardless of its source; or (d) a trust if it is subject to the primary supervision of a court within the United States and one or more U.S. persons have the authority to control all substantial decisions of the trust or has a valid election in effect under applicable U.S. Treasury regulations to be treated as a U.S. person.

If a partnership (or other entity or arrangement treated as a partnership for U.S. federal income tax purposes) holds our ordinary shares, the U.S. federal income tax treatment of a partner in such partnership will generally depend on the status of the partner and the activities of the partnership. A partner of a partnership holding our ordinary shares is urged to consult its own tax advisor regarding tax consequences of an investment in our ordinary shares.

Each U.S. Holder considering an investment in, or holding or disposing of, our ordinary shares is urged to consult his or her own tax advisor concerning the U.S. federal, state, local, and non-U.S. income and other tax consequences of the purchase, ownership, and disposition of our ordinary shares in light of such U.S. Holder's particular circumstances.

Passive Foreign Investment Company Rules

The Company will be treated as a passive foreign investment company ("PFIC") for U.S. federal income tax purposes for any taxable year in which either: (a) at least 75% of our gross income for such taxable year is passive income; or (b) at least 50% of the value of our assets (determined on the basis of a quarterly average) during such year is attributable to assets that produce, or are held for the production of, passive income. For this purpose, passive income generally includes dividends, interest, royalties, rents (other than rents and royalties derived in the active conduct of a trade or business and not derived from a related person), annuities, and gains from assets that produce passive income. If we, directly or indirectly, own at least 25% (by value) of the stock of another corporation, we will be treated, for purposes of the PFIC tests, as owning our proportionate share of the other corporation's assets and receiving our proportionate share of the other corporation's income.

The annual PFIC determination to be made by a U.S. Holder of our ordinary shares is an inherently factual determination based upon the application of complex U.S. federal income tax rules (which are subject to differing interpretations), the composition of our income and assets from time to time, and the nature of the activities performed by our officers and employees. Although the determination of PFIC status is subject to factual uncertainties because it depends upon the valuation of our ordinary shares as well as our goodwill and other assets and income and because there are uncertainties in the application of the relevant rules, we are uncertain if we would be considered to be a PFIC for Fiscal 2025. In addition, as the determination of PFIC status is made on an annual basis and depends on variables over which we have limited control, there can be no assurance that we will not be classified as a PFIC for 2026 or any future calendar years.

If we are determined to be a PFIC for any taxable year, a U.S. Holder that holds our ordinary shares may experience certain adverse tax consequences. Such U.S. Holder could be liable for additional taxes and interest charges upon (i) distributions received by the U.S. Holder on our ordinary shares during the year, but only to the extent that the aggregate of distributions for the taxable year exceeds 125% of the average amount of distributions received by the U.S. Holder during the shorter of the preceding three years or the U.S. Holder's holding period for the ordinary shares, or (ii) upon a sale or other disposition of the ordinary shares at a gain, whether or not we continue to be a PFIC (each an "excess distribution"). The tax will be determined by allocating the excess distribution ratably to each day of the U.S. Holder's holding period. The amount allocated to the current taxable year and any taxable year with respect to which we were not a PFIC will be taxed as ordinary income (rather than capital gain) earned in the current taxable year. The amount allocated to other taxable years will be taxed at the highest marginal rates applicable to ordinary income for such taxable years and, in addition, an interest charge will be imposed on the amount of such taxes.

A U.S. Holder that holds ordinary shares in any year in which the Company is classified as a PFIC may make a "deemed sale" election in a subsequent taxable year in which the Company is not classified as a PFIC. If a valid deemed sale election is made, the U.S. Holder will be treated as having sold all of its ordinary shares for their fair market value on the last day of the last taxable year in which the Company was classified as a PFIC, and the ordinary shares will no longer be treated as PFIC stock (provided the Company is not reclassified as a PFIC in a subsequent year). Any gain recognized as a result of the deemed sale will be subject to tax as an excess distribution received on the last day of the last taxable year in which the Company was classified as a PFIC. The U.S. Holder's tax basis in the ordinary shares will be increased to reflect the gain recognized, and the U.S. Holder's holding period will begin on the day after the Company ceased to be classified as a PFIC. No loss may be recognized in connection with a deemed sale election.

---

U.S. Holders may also be required to file certain information returns with the Internal Revenue Service in connection with an investment in a PFIC.

A U.S. Holder can avoid certain of the adverse rules described above by making a mark-to-market election with respect to its ordinary shares, provided that the ordinary shares are "marketable." Ordinary shares will be marketable if they are "regularly traded" on a "qualified exchange" or other market within the meaning of applicable Treasury regulations. If a U.S. Holder makes the mark-to-market election, it generally will recognize as ordinary income any excess of the fair market value of the ordinary shares at the end of each taxable year over their adjusted tax basis, and will recognize an ordinary loss in respect of any excess of the adjusted tax basis of the ordinary shares over their fair market value at the end of the taxable year (but only to the extent of the net amount of income previously included as a result of the mark-to-market election). If a U.S. Holder makes the election, the holder's tax basis in the ordinary shares will be adjusted to reflect the income or loss amounts recognized. Any gain recognized on the sale or other disposition of ordinary shares in a year when the Company is a PFIC will be treated as ordinary income and any loss will be treated as an ordinary loss (but only to the extent of the net amount of income previously included as a result of the mark-to-market election).

In addition, in order to avoid the application of the foregoing rules, a U.S. Holder that owns stock in a PFIC for U.S. federal income tax purposes may make a "qualified electing fund" election (a "QEF Election") with respect to such PFIC if the PFIC provides the information necessary for such election to be made. If a U.S. Holder makes a QEF Election with respect to a PFIC, the U.S. Holder will be currently taxable on its pro rata share of the PFIC's ordinary earnings and net capital gain (at ordinary income and capital gain rates, respectively) for each taxable year that the entity is classified as a PFIC and will not be required to include such amounts in income when actually distributed by the PFIC. We do not intend to provide information necessary for U.S. Holders to make qualified electing fund elections.

Prospective investors are urged to consult their own tax advisors regarding the U.S. federal income tax consequences of an investment in a PFIC, including the availability of any elections that may be available to mitigate the adverse consequences described above.

Sale or Other Disposition of Ordinary Shares

Subject to the discussion above under "Passive foreign investment company rules", a U.S. Holder will generally recognize capital gain or loss upon the sale or other disposition of our ordinary shares in an amount equal to the difference between the amount realized upon the disposition and the holder's adjusted tax basis in such ordinary shares. Any such capital gain or loss will be long-term if the ordinary shares have been held for more than one year and will generally be United States source gain or loss for United States foreign tax credit purposes. The deductibility of capital losses is subject to significant limitations. U.S. Holders are urged to consult their tax advisors regarding the tax consequences if a foreign withholding tax is imposed on a disposition of the ordinary shares, including the availability of the foreign tax credit under such U.S. Holder's particular circumstances.

Foreign Financial Asset Reporting

Certain U.S. Holders are required to report information to the Internal Revenue Service relating to an interest in "specified foreign financial assets," including shares issued by a non-United States corporation, for any year in which the aggregate value of all specified foreign financial assets exceeds $50,000 (or a higher dollar amount prescribed by the Internal Revenue Service), subject to certain exceptions. These rules also impose penalties if a holder is required to submit such information to the Internal Revenue Service and fails to do so. U.S. Holders are urged to consult their tax advisors regarding the possible application of these rules, including the application of the rules to their particular circumstances.

Backup Withholding Tax and Information Reporting

Proceeds from the sale or other disposition of a U.S. Holder's ordinary shares may be subject to information reporting to the Internal Revenue Service and, in certain circumstances, to U.S. federal backup withholding. Certain exempt recipients are not subject to these information reporting requirements. Backup withholding will not apply to a U.S. Holder who furnishes a correct taxpayer identification number and makes any other required certification, or who is otherwise exempt from backup withholding. U.S. Holders who are required to establish their exempt status generally must provide Internal Revenue Service Form W-9 (Request for Taxpayer Identification Number and Certification).

Backup withholding is not an additional tax. Amounts withheld as backup withholding may be credited against a U.S. Holder's U.S. federal income tax liability. A U.S. Holder may obtain a refund of any excess amounts withheld under the backup withholding rules by filing the appropriate claim for refund with the Internal Revenue Service in a timely manner and furnishing any required information.

Prospective investors should consult their own tax advisors as to their qualification for an exemption from backup withholding and the procedure for obtaining this exemption.

**J. ANNUAL REPORT TO SECURITY HOLDERS** 

Not applicable.

**ITEM 11. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK**

**Foreign Currency Risks**

The Company is exposed to market risk arising from changes in foreign currency exchange rates. The Company's revenues are denominated in Hong Kong Dollars and Renminbi. The majority of the Company's expenses and cost of revenues are denominated in Hong Kong Dollars, followed by Renminbi, U.S. Dollars, Japanese yen, and euros. As a result, the Company is subject to risks associated with fluctuations in the relative values of the U.S. Dollar, Hong Kong Dollar, Renminbi, Japanese yen, and euro.

The Company does not currently maintain a hedging program with respect to its foreign currency exchange rate exposure. Any material appreciation in the value of the Hong Kong Dollar, Renminbi, Japanese yen, or euro relative to the U.S. Dollar could increase the Company's expenses and cost of revenues and could therefore have a material adverse effect on the Company's business, financial condition, and results of operations.

**Inflation Risk**

The Company cannot determine with precision the effect of inflation on its operations. The Company does not believe that inflation has had a material effect on its revenues or results of operations during the periods covered by this Annual Report. However, there can be no assurance that the Company will not be materially affected by higher rates of inflation in future periods.

If the rate of inflation in mainland China increases, the PRC government may introduce measures intended to reduce inflationary pressures. Any such measures may not be successful in reducing or slowing the rate of inflation, and efforts by the PRC government to curb inflation may simultaneously curb economic growth, increase the Company's overhead costs, and adversely affect the Company's revenues. Sustained or increased inflation in mainland China could have an adverse impact on the broader PRC economy and could materially and adversely affect the Company's business and financial results.

**Interest Rate Risk**

The Company is not currently exposed to material earnings or cash flow risk arising from changes in interest rates on debt obligations, as the Company had no material bank indebtedness. The Company does not currently anticipate entering into interest rate swap agreements or similar instruments.

**PART II**

**ITEM 13. DEFAULTS, DIVIDEND ARREARAGES AND DELINQUENCIES**

None.

**ITEM 14. MATERIAL MODIFICATIONS TO THE RIGHTS OF SECURITY HOLDERS AND USE OF PROCEEDS**

On September 20, 2011, the Company received a deficiency letter from Nasdaq notifying the Company that it was no longer in compliance with Nasdaq's minimum bid price listing maintenance requirement, as the closing bid price of the Company's ordinary shares had fallen below US$1.00 per share for 30 consecutive trading days. In order to regain compliance with this requirement, in January 2012, the Company effected a reverse share split of its ordinary shares at a ratio of two shares for every eleven shares previously outstanding (the "Reverse Split").

To facilitate the Reverse Split, the Company amended the par value of its ordinary shares from US$0.01 per share to no par value.

In connection with the Reverse Split and to comply with applicable Nasdaq listing rules, in November 2011 and January 2012 the Company filed an Amended and Restated Memorandum and Articles of Association with the Registry of Corporate Affairs of the BVI Financial Services Commission. The amendments served, among other purposes, to: (i) disapply the Transitional Provisions carried forward from the International Business Companies Act (the "IBC Act") upon the Company's automatic re-registration under the BVI Business Companies Act (as amended, the "BC Act") on January 1, 2007; and (ii) remove from the Company's constitutional documents the IBC Act concepts of authorized capital, capital accounts, and surplus accounts, thereby eliminating a layer of requirements that would otherwise apply to share splits, reverse share splits, redemptions, and dividends. The Company's accounting treatment of share capital was not affected by these amendments. A summary of the amendments is set out in the Company's Forms 6-K filed with the SEC on November 30, 2011 and February 6, 2012, which are incorporated herein by reference.

For a more detailed description of the Company's corporate history, re-registration under the BC Act, and the terms of the Company's Amended and Restated Memorandum and Articles of Association, see "Item 10.B — Memorandum and Articles of Association."

**ITEM 15. CONTROLS AND PROCEDURES**

**Evaluation of Disclosure Controls and Procedures**

As required by Rules 13a-15(b) and 15d-15(b) under the Exchange Act, our management, with the participation of our Chief Executive Officer and Chief Financial Officer, has evaluated the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act), as of the end of the period covered by this Annual Report on Form 20-F.

Disclosure controls and procedures are defined under SEC rules as controls and other procedures that are designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported within required time periods. Disclosure controls and procedures include controls and procedures designed to ensure that information is accumulated and communicated to the issuer's management, including its principal executive and principal financial officers, or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosures.

There are inherent limitations to the effectiveness of any system of disclosure controls and procedures, including the possibility of human error and the circumvention or overriding of the controls and procedures. Accordingly, even effective disclosure controls and procedures can only provide reasonable assurance of achieving their control objectives.

Based on such evaluation, our Chief Executive Officer and Chief Financial Officer have concluded that, as of December 31, 2025, our disclosure controls and procedures were not effective to accomplish their objectives at the reasonable assurance level.

**Management's Annual Report on Internal Control over Financial Reporting**

Our management, under the supervision of our Chief Executive Officer and Chief Financial Officer, is responsible for establishing and maintaining adequate internal control over financial reporting as defined in Rule 13a-15(f) and Rule 15d-15(f) of the Exchange Act. Our internal control system was designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation and fair presentation of our consolidated financial statements for external purposes in accordance with generally accepted accounting principles. Our Chief Executive Officer and Chief Financial Officer assessed the effectiveness of our internal control over financial reporting as of December 31, 2025. In making this assessment, they used the criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission ("COSO").

Based on this assessment, our management has identified two significant deficiencies in our internal control over financial reporting. As defined in the standards established by the PCAOB, a "significant deficiency" is a control deficiency, or combination of control deficiencies, that adversely affects the company's ability to initiate, authorize, record, process, or report external financial data reliably in accordance with generally accepted accounting principles such that there is more than a remote likelihood that a misstatement of the company's annual or interim financial statements that is more than inconsequential will not be prevented or detected; and a "control deficiency" exists when the design or operation of a control does not allow management or employees, in the normal course of performing their assigned functions, to prevent or detect misstatements on a timely basis.

---

| |
|:---|
| 95 |
| *[**Table of Contents**](#TOC)* |

---

The significant deficiency identified relates to a lack of segregation of duties in bank payment processes. To remediate this deficiency, management has determined that dual payment authorization may need to be implemented for all bank accounts, such that no single individual has the ability to both initiate and approve bank transactions. This control enhancement is intended to strengthen oversight over cash disbursements and reduce the risk of unauthorized or inappropriate payments.

Although dual signatory authorization is not currently required for certain bank accounts, management has established procedures under which bank payments are subject to review and approval by different parties involved in the payment process. Specifically, the initiation and approval of payments are performed by separate individuals. Management believes that these procedures provide an appropriate level of oversight and function as compensating controls to partially address the risks associated with limited segregation of duties.

Notwithstanding the existence of significant deficiencies as described above, our management believes that our consolidated financial statements contained in this Annual Report fairly present our financial position, results of operations and cash flows for the years covered thereby in all material respects.

**Changes in Internal Controls over Financial Reporting**

Other than as described above, there were no changes in our internal controls that occurred during the period covered by this Annual Report that has materially affected, or is reasonably likely to materially affect our internal control over financial reporting.

**ITEM 16. [RESERVED]**

**ITEM 16A. AUDIT COMMITTEE FINANCIAL EXPERT**

Our Board of Directors has determined that Mr. Yi Sun, an independent director of the Company (under the standards set forth in Rule 10A-3 of the Exchange Act and the NASDAQ listing rules) and a member of our Audit Committee, meets the criteria for an "audit committee financial expert" as such term is defined in Item 407 of Regulation S-K promulgated by the SEC.

**ITEM 16B. CODE OF ETHICS**

Our Board of Directors has adopted a Code of Business Conduct and Ethics that applies to all of our directors, officers, and employees, including provisions that specifically apply to our chief executive officer, chief financial officer. and any other persons who perform similar functions for us. The Company will provide a copy of the Code of Business Conduct and Ethics, without charge, to any person who submits a written request to our offices at the address set forth on the cover page of this Annual Report. The Company will respond to all such requests within ten business days of receipt.

**ITEM 16C. PRINCIPAL ACCOUNTANT FEES AND SERVICES**

The following table sets forth the aggregate fees billed by J&S, our principal independent registered public accounting firm, in connection with professional services rendered for the fiscal years ended December 31, 2025 and December 31, 2024. No fees other than those set forth below were paid to J&S during the periods indicated.

The Audit Committee has adopted a pre-approval policy for the engagement of the Company's independent registered public accounting firm to perform permitted audit and non-audit services. Under this policy, which is designed to ensure that such engagements do not impair the independence of the Company's auditors, the Audit Committee pre-approves annually a range of specific audit and non-audit services in the categories of audit services, audit-related services, tax services, and other services that may be performed by the Company's independent registered public accounting firm, together with the maximum pre-approved fees payable as compensation for each category of pre-approved service. Any proposed services exceeding the applicable maximum pre-approved fees require specific prior approval by the Audit Committee.

**ITEM 16D. EXEMPTIONS FROM THE LISTING STANDARDS FOR AUDIT COMMITTEES**

The Company is subject to Rule 10A-3 under the Exchange Act, which requires that the audit committee of a listed company be composed entirely of independent directors, subject to certain exemptions.

The Company does not rely on any exemption from the audit committee independence requirements of Rule 10A-3 or Nasdaq Listing Rule 5605(c)(2)(A). The Company's Audit Committee currently consists of three members — Yi Sun, Janet Cheang, and Fu Ming Chen — each of whom the Board of Directors has determined satisfies the applicable independence requirements under Rule 10A-3 of the Exchange Act and Nasdaq Listing Rule 5605(a)(2). The Company is therefore in full compliance with the audit committee composition and independence requirements applicable to listed companies under Rule 10A-3 and Nasdaq Listing Rule 5605(c)(2)(A).

The Board of Directors has determined that Yi Sun meets the criteria for an "audit committee financial expert" as such term is defined in Item 407 of Regulation S-K, and that Mr. Sun qualifies as an independent director under the standards set forth in Rule 10A-3 of the Exchange Act and the Nasdaq listing rules.

Accordingly, no exemption from the listing standards for audit committees is being claimed or relied upon by the Company in connection with this Annual Report.

**ITEM 16E. PURCHASES OF EQUITY SECURITIES BY THE ISSUER AND AFFILIATED PURCHASERS**

**Share Repurchase Program**

On February 20, 2025, our board of director approved a share repurchase program to repurchase up to 350,000 ordinary shares for an aggregate purchase price of not more than US$500,000 over a period of one year (the "2025 Repurchase Program"). The 2025 Repurchase Program expired on February 19, 2026.

On March 3, 2026, our board of director approved a share repurchase program to repurchase up to 250,000 ordinary shares for an aggregate purchase price of not more than US$350,000 over a period of one year (the "2026 Repurchase Program"). The 2026 Repurchase Program will expire on March 2, 2027.

During Fiscal 2025, we repurchased an aggregate of 271,787 ordinary shares for an aggregate consideration of approximately US$318,593 under the 2025 Repurchase Program, at a weighted average price of approximately US$1.17 per share.

The table below summarizes all repurchases of the Company's ordinary shares made during Fiscal 2025.

**ITEM 16F. CHANGE IN REGISTRANT'S CERTIFYING ACCOUNTANT**

No change in the Company's certifying accountant occurred during Fiscal 2024 or Fiscal 2025, and no change occurred during any subsequent interim period prior to the filing of this Annual Report. Accordingly, the disclosure requirements of Item 16F(a) are not applicable with respect to Fiscal 2024 or Fiscal 2025.

**ITEM 16G. CORPORATE GOVERNANCE**

The Company is a foreign private issuer within the meaning of the rules promulgated under the Exchange Act. The Company's ordinary shares are listed on Nasdaq, and the Company is therefore subject to Nasdaq's corporate governance requirements. In addition, as a company incorporated in the BVI, the Company's corporate governance practices are also governed by applicable BVI law and the Company's Memorandum and Articles of Association.

**Foreign Private Issuer Exemptions**

As a foreign private issuer, the Company is permitted under Nasdaq Listing Rule 5615(a)(3) to follow home country corporate governance practices in lieu of certain Nasdaq corporate governance requirements. The Company's BVI counsel has provided a letter to Nasdaq certifying that the Company's practice of following the provisions of BVI law and its Memorandum and Articles of Association in lieu of certain Nasdaq corporate governance rules is not prohibited under any statutory provision of BVI law. The following summarizes the material ways in which the Company's corporate governance practices differ from the requirements applicable to domestic U.S. issuers under the Nasdaq listing standards:

---

| |
|:---|
| 98 |
| *[**Table of Contents**](#TOC)* |

---

**Controlled Company Exemption**

The Company has been designated as a "Controlled Company" under Nasdaq Listing Rule 5615(c), as a majority of the Company's outstanding ordinary shares are beneficially owned by T.C. Leung, who has disclosed his status as a "control person" in his filings with the SEC. As a Controlled Company, the Company is exempt from the following Nasdaq corporate governance requirements:

---

| |
|:---|
| the requirement that a majority of the Board of Directors be comprised of independent directors (Nasdaq Listing Rule 5605(b)(1)); |
| the requirement that the compensation of the Chief Executive Officer be determined or recommended solely by a majority of the independent directors or a compensation committee comprised solely of independent directors (Nasdaq Listing Rule 5605(d)); and |
| the requirement that director nominations be determined or recommended solely by a majority of the independent directors or a nominations committee comprised solely of independent directors (Nasdaq Listing Rule 5605(e)). |

---

The Company does not have a stand-alone compensation committee or a nomination and corporate governance committee. As a result, shareholders may not have the same protections afforded to shareholders of companies subject to all Nasdaq corporate governance requirements applicable to U.S. domestic issuers.

**Audit Committee**

Nasdaq Listing Rule 5605(c)(2)(A) requires each listed company to have, and to maintain, an audit committee of at least three members, all of whom must satisfy the independence requirements of Nasdaq Listing Rule 5605(a)(2) and Rule 10A-3 under the Exchange Act. The Company's Audit Committee currently consists of three members — Yi Sun, Janet Cheang, and Fu Ming Chen — each of whom the Board of Directors has determined satisfies the applicable independence requirements. The Company is in compliance with Nasdaq Listing Rule 5605(c)(2)(A).

**Section 16(a) Reporting Obligations**

Historically, the Company's officers, directors, and shareholders owning more than 10% of the Company's ordinary shares were exempt from the reporting obligations and short-swing profit recovery provisions of Section 16 of the Exchange Act pursuant to Rule 3a12-3 thereunder, and were therefore not required to file reports of their beneficial ownership of, or transactions in, the Company's ordinary shares on Forms 3, 4, and 5 with the SEC.

On December 18, 2025, the Holding Foreign Insiders Accountable Act (the "Act") was signed into law. The Act amends Section 16(a) of the Exchange Act to require directors and officers of foreign private issuers — including the Company — to publicly report their beneficial ownership of, and transactions in, the equity securities of the relevant foreign private issuer by filing reports on the SEC's EDGAR system. The new reporting requirements became effective on March 18, 2026, 90 days after the Act's enactment.

| *[**Table of Contents**](#TOC)* |

---

As amended by the Act, Section 16(a) requires the Company's directors and officers to file the following reports on EDGAR:

---

| |
|:---|
| **Form 3** — an initial statement of beneficial ownership, due at the time the Company's securities are registered on a national securities exchange, within 10 days of an individual becoming a director or officer, or by March 18, 2026 for existing directors and officers; |
| **Form 4** — a report of any change in beneficial ownership, due before the end of the second business day following the day on which the relevant transaction is executed; and |
| **Form 5** — an Annual Report covering transactions not previously reported on Form 4, due within 45 days after the end of the Company's fiscal year. |

---

The Section 16(a) reporting requirements as amended by the Act do not apply to beneficial owners of more than 10% of the Company's registered equity securities, who remain subject to the separate reporting requirements of Sections 13(d) and 13(g) of the Exchange Act. In addition, the Company's directors and officers remain exempt from the short-swing profit recovery provisions of Section 16(b) of the Exchange Act.

The Company is incorporated in the Cayman Islands, which is not a qualifying jurisdiction under the SEC's exemptive order dated March 5, 2026, and accordingly the Company's directors and officers are not eligible to rely on such exemptive relief and are fully subject to Section 16(a) reporting requirements.

The Company's directors and officers were required to file their initial ownership reports on Form 3 by March 18, 2026. Certain of the Company's directors and officers have filed, or are in the process of filing, their Form 3 initial ownership reports on a delayed basis. The Company is working with its directors and officers to ensure that all required filings are completed as promptly as practicable and that appropriate procedures are established to ensure timely ongoing compliance with Section 16(a) reporting obligations going forward, including Form 4 filings required within two business days of any reportable transaction.

**General**

The Company believes it is in compliance with all applicable Nasdaq corporate governance rules currently in effect and intends to comply with any future changes to those rules no later than the date on which such changes become effective.

**ITEM 16K. CYBERSECURITY** 

**Risk Management and Strategy**

We have implemented processes for assessing, identifying and managing material risks from cybersecurity threats and monitoring the prevention, detection, mitigation and remediation of material cybersecurity incidents. We have also integrated cybersecurity risk management into our overall enterprise risk management system.

We have established a dynamic and multi-layered cybersecurity defense system to effectively mitigate both internal and external cybersecurity threats. This comprehensive system spans multiple security domains, including network, host, and application layers. It integrates a range of security capabilities such as threat defense, continuous monitoring, in-depth analysis and rapid response. Our approach to managing cybersecurity risks and safeguarding sensitive data is multi-faceted, involving technological safeguards, procedural protocols, a rigorous program of surveillance on our corporate network, ongoing internal and external evaluations of our security measures, a solid incident response framework, and regular cybersecurity training sessions for our employees. Our cybersecurity department is actively engaged in continuous monitoring of our applications, platforms and infrastructure to ensure prompt identification and response to potential issues, including emerging cybersecurity threats.

We regularly engage third parties to assess our internal cybersecurity programs and compliance with applicable practices and standards. The bug bounty program we have established enables independent security researchers to aid us in identifying potential vulnerabilities and further mitigating risks. We have implemented a set of procedures to ensure effective management of the cybersecurity risks associated with the use of third-party service providers. These procedures include, but are not limited to, conducting cybersecurity assessments and tracking the capabilities and qualifications of third-party security service providers through our supplier assessment process. Additionally, for independent security researchers, we require adherence to the security-related agreement when submitting vulnerabilities.

As of the date of this Annual Report, we have not experienced any material cybersecurity incidents or identified any material cybersecurity threats that have affected or are reasonably likely to materially affect us, our business strategy, results of operations or financial condition.

**Governance**

Our board of directors is responsible for overseeing our cybersecurity risk management. Our board of directors: (i) maintain oversight of the disclosure related to cybersecurity matters in current reports or periodic reports of our company, (ii) review updates to the status of any material cybersecurity incidents or material risks from cybersecurity threats to our company, and the disclosure issues, if any, presented by our cybersecurity officer on a quarterly basis, and (iii) review disclosure concerning cybersecurity matters in our Annual Report on Form 20-F presented by our cybersecurity officer.

At management level, our cybersecurity committee is responsible for overseeing the process of assessing, identifying and managing material risks from cybersecurity threats to our company and monitoring the prevention, detection, mitigation and remediation of material cybersecurity incident. Our cybersecurity officer, as the management representative of our cybersecurity committee, reports to our board of directors on (i) a quarterly basis on updates to the status of any material cybersecurity incidents or material risks from cybersecurity threats to our company, and the disclosure issues, if any, and (ii) on disclosure concerning cybersecurity matters in our Annual Report on Form 20-F.

If a cybersecurity incident occurs, our cybersecurity department will promptly organize personnel for internal assessment and report to our cybersecurity committee. If it is further determined that the incident could potentially be a material cybersecurity event, our cybersecurity officer will promptly report the incident and assessment results to our disclosure committee and external legal counsel to the extent appropriate. Our cybersecurity officer shall prepare disclosure material on the cybersecurity incident for review and approval by our disclosure committee and board of directors, before it is disseminated to the public.

**REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM**

To: The Board of Directors and Shareholders of Euro Tech Holdings Company Limited

**Opinion on the Financial Statements**

We have audited the accompanying consolidated balance sheets of Euro Tech Holdings Company Limited (the "Company") and its subsidiaries (the "Group") as of December 31, 2025 and 2024, and the related consolidated statements of operations and comprehensive income, consolidated statement of changes in shareholders' equity, and consolidated statements of cash flows for each of the three years in the period ended December 31, 2025, and the related notes to the consolidated financial statements and schedule (collectively referred to as the "financial statements"). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Group as of December 31, 2025 and 2024, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2025, in conformity with accounting principles generally accepted in the United States of America.

**Basis for Opinion**

These financial statements are the responsibility of the Group's management. Our responsibility is to express an opinion on the Group's financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) ("PCAOB") and are required to be independent with respect to the Group in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Group is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits, we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Group's internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

**Critical Audit Matters** 

Critical audit matters are matters arising from the current year audit of the financial statements that were communicated or are required to be communicated to the audit committee and that: (1) relate to accounts or disclosures that are material to the financial statements, and (2) involved especially challenging, subjective, or complex judgments.

The communication of critical audit matters does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matters below, providing separate opinions on the critical audit matters or on the accounts or disclosures to which they relate.

*Revenue Recognition – Contracts recognised over time*

As described in Note 2 to the consolidated financial statements, the Group adopted Accounting Standards Codification (ASC) Topic 606, Revenue from Contracts with Customers. Under this standard, the Group recognizes revenue over time, reflecting the continuous transfer of control of goods or services to the customer. Revenue is measured using the output method, based on the achievement of contractual billing milestones.

We identified revenue recognition using the output method as a critical audit matter due to the significant judgments involved in determining the timing and amount of revenue recognized. These judgments include assessing the point at which control transfers to the customer, interpreting contractual terms, and evaluating whether revenue was appropriately recorded based on milestones achieved. The complexity and subjectivity associated with these assessments required extensive audit effort and a high degree of auditor judgment.

Our key consideration is our evaluation of revenue recognition involves assessing the appropriateness of the Group's application of ASC 606, including the identification and measurement of performance obligations, the determination of the stages of works certified by customers, and the classification of contract assets and liabilities. Our audit procedures to assess the above include:

1. Understand and evaluate the Group's revenue recognition policies and procedures including the adoption and application of ASC 606;

2. Evaluate the identification and measurement of performance obligations, including the Group's determination of whether they are distinct or combined;

3. Assess the methodology used to measure progress towards complete satisfaction of performance obligations over time, including the use of the output method or reliance on customer-certified progress;

4. Verify and review the classification and accuracy of contract assets and liabilities;

5. Test samples of progress billing to billing milestone as stipulated on contracts to ensure reasonable accuracy and completeness of revenue recognition;

6. Validate costs incurred for projects not yet completed at year end and revenue earned not yet billed to the customer (contract assets) and validate amounts received in advance from customers for work not yet completed (contract liabilities);

7. Validate invoices billed to customers subsequent to financial year end for revenue earned as at financial year end and validate receipt of payments for these invoices;

8. Reperformed the calculation of the revenue based on the percentage of completion method and where applicable, considered the implications of any changes in estimates; and

9. Assess the adequacy of the Group's disclosures related to revenue recognition under ASC 606.

**EURO TECH HOLDINGS COMPANY LIMITED**

**NOTES TO CONSOLIDATED FINANCIAL STATEMENTS**

**FOR THE YEARS ENDED DECEMBER 31, 2025, 2024 AND 2023**

**Note 2: Summary of Significant Accounting Policies** 

The accompanying consolidated financial statements reflect the application of certain significant accounting policies as described in this note and elsewhere in the accompanying consolidated financial statements and notes.

· Use of estimates

The preparation of the accompanying consolidated financial statements in conformity with GAAP requires management to make estimates and judgments that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Certain accounting estimates of the Group require a higher degree of judgment than others in their application. These include the recognition of revenue and earnings from engineering contracts over time, the valuation of goodwill, and contract assets and contract liabilities. Management continually evaluates all of its estimates and judgments based on available information and experience; however, actual results could differ from these estimates.

· Basis of consolidation

The accompanying consolidated financial statements include the results of operations of the Company and its subsidiaries. Significant intercompany transactions and balances have been eliminated.

· Subsidiaries

Subsidiaries are all entities over which the Group has control; has the power to appoint or remove the majority of the members of the board of directors; has the right to cast a majority of votes at the meeting of the board of directors or to govern the financial and operating policies of the investee under a statute or agreement among the shareholders or equity holders.

· Investments in affiliates

We account for our interest in an investment using the equity method of accounting per Accounting Standards Codification ("ASC") No. 323, "Investments - Equity Method and Joint Ventures" if we are not the primary beneficiary of a VIE or do not have a controlling interest. The investment is recorded at cost and the carrying amount is adjusted periodically to recognize our proportionate share of income or loss, additional contributions made and dividends and capital distributions received. We record the effect of any impairment or other than temporary decrease in the value of the investment.

In the event a partially owned equity affiliate were to incur a loss and our cumulative proportionate share of the loss exceeded the carrying amount of the equity method investment, application of the equity method would be suspended and our proportionate share of further losses would not be recognized unless we committed to provide further financial support to the affiliate. We would resume application of the equity method once the affiliate became profitable and our proportionate share of the affiliate's earnings equals our cumulative proportionate share of losses that were not recognized during the period the application of the equity method was suspended.

· Non-controlling interests

For entities that are consolidated, but not 100% owned, a portion of the income or loss and equity is allocated to owners other than the Group. The aggregate of the income or loss and corresponding equity that is not owned by the Group is included within non-controlling interests in the consolidated financial statements.

**EURO TECH HOLDINGS COMPANY LIMITED**

**NOTES TO CONSOLIDATED FINANCIAL STATEMENTS**

**FOR THE YEARS ENDED DECEMBER 31, 2025, 2024 AND 2023**

Non-controlling interests is presented as a separate component of equity in the consolidated balance sheets. Net income includes the net income attributable to the holders of non-controlling interests in the consolidated statements of operations and comprehensive income / (loss). Profits and losses are allocated to non-controlling interests in proportion to their relative ownership interests regardless of their basis.

· Non-controlling interest – put option

The management evaluates all of its financial instruments, including issued put options, to determine their appropriate classification as either liabilities or equity, following the criteria's outlined in ASC 480, " Distinguishing Liabilities from Equity". The Group has determined that the put option held by non-controlling interest will be recorded as equity if the fair value of the put option becomes material.

· Segment information

The Group reports segment information based on the "management" approach. The management approach designates the internal reporting used by management for making decisions and assessing performance as the source of the Group's reportable segments. The Group categorizes its operations into two business segments: Trading and manufacturing, and Engineering.

· Revenue recognition

The Company follows the revenue standard Accounting Standards Codification ("ASC") 606, Revenue from Contracts with Customers.

The core principle of the revenue standard is that a company should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. The following five steps are applied to achieve that core principle:

Step 1: Identify the contract with the customer

Step 2: Identify the performance obligations in the contract

Step 3: Determine the transaction price

Step 4: Allocate the transaction price to the performance obligations in the contract

Step 5: Recognize revenue when the company satisfies a performance obligation.

Our revenue is derived from both short and long-term contracts for customers in our engineering segment, as well as short-term contracts for customers in our trading and manufacturing segment. Accounting treatment for these contracts in accordance with Accounting Standards Update ("ASU") 2014-09 (Accounting Standards Codification ("ASC") Topic 606, Revenue from Contracts with Customer), is as follows:

<u>Performance obligations satisfied over time (Engineering services)</u>

Recognition of performance obligations

A performance obligation is a promise in a contract to transfer a distinct good or service to the customer, and is the unit of account in the new revenue standard. The contract transaction price is allocated to each distinct performance obligation and recognized as revenue when, or as, the performance obligation is satisfied.

Engineering service projects typically span between several days to over 5 years. The majority of our long-term contracts have a single performance obligation as the promise to transfer the individual goods or services is not separately identifiable from other promises in the contracts and, therefore, is not distinct. Some contracts have multiple performance obligations, most commonly due to the contract covering multiple phases of the project life cycle. Revenues are recognized as our obligations are satisfied over time, by reference to the progress towards complete satisfaction of that performance obligation.

**EURO TECH HOLDINGS COMPANY LIMITED**

**NOTES TO CONSOLIDATED FINANCIAL STATEMENTS**

**FOR THE YEARS ENDED DECEMBER 31, 2025, 2024 AND 2023**

If the Group expects the reference to progress certificates issued by the customers, with additional adjustments where necessary, depicts the Group's performance in transferring control of goods or services promised to customers for individual projects, the Group satisfies the performance obligation over time and therefore, recognizes revenue over time in accordance with the output method for measuring progress. Under output method, revenue recognition is based on the stage of completion of the contracts, provided that the stage of contract completion and the gross billing value of contracting work can be measured reliably. The stage of completion of a contract is established by reference to the contract based on billing milestone or stage of work certified by customer. Generally, invoices are billed upon fulfilment of the measurable performance obligation. The Company evaluates the progress towards completion of the performance obligation at each phase of the contract and bills the customer in accordance with the price agreed upon on the contract.

Remaining performance obligations ("RPOs")

RPOs represent the amount of revenues we expect to recognize in the future from our contract commitments on projects and are hereafter referred to as "Backlog". Backlog includes the entire expected revenue values for subsidiary we consolidate. Backlog may not be indicative of future operating results, and projects included in Backlog may be canceled, modified or otherwise altered by customers.

The following schedule shows a reconciliation of backlog representing the amount of revenue the Company expects to realize from work to be performed on uncompleted contracts in progress at December 31, 2025 and 2024, and from contractual agreements in effect at December 31, 2025, on which work has not yet begun:

---

| | |
|:---|:---|
|  | **US$'000** |
| Contract revenue on uncompleted contracts at December 31, 2023 | 4022 |
| New contract awards during the year | 5621 |
| Contract adjustment | 30 |
| Contract revenue recognized for the year | (5834) |
| Backlog at December 31, 2024 | 3839 |
| Contract revenue on uncompleted contracts at December 31, 2024 | 3839 |
| New contract awards during the year | 6272 |
| Contract adjustment |  |
| Contract revenue recognized for the year | (5881) |
| Backlog at December 31, 2025 | 4230 |

---

Our backlog increased from US$3,839,000 as of December 31, 2024 to US$4,230,000as of December 31, 2025, representing an increase of US$391,000. The increase in our backlog was primarily due to the delay in completion and fulfillment of existing orders by us in some of our existing projects. Nevertheless, the timing and extent to which backlog will result in direct revenue depends on many factors, including the timing of commencement of work, the rate at which we perform services, scope changes, cancellations, delays, receipt of regulatory approvals and the nature, duration, size, complexity and phase of the studies. In addition, delayed projects remain in backlog until they are canceled. As a result of these factors, our backlog is not necessarily a reliable indicator of future direct revenue and we might not realize all or any part of the direct revenue from the authorizations in backlog as of any point in time.

Variable consideration

Contract modifications through change orders, claims and incentives are routine in the performance of the Group's contracts to account for changes in the contract specifications or requirements. In most instances, contract modifications are not distinct from the existing contract due to the significant integration service provided in the contract and are accounted for as a modification of the existing contract and performance obligation. Either the Group or its customers may initiate change orders, which may include changes in specifications or designs, manner of performance, facilities, equipment, materials, sites and period of completion of the work. Change orders that are unapproved as to both price and scope are evaluated as claims. The Group considers claims to be amounts in excess of approved contract prices that the Group seeks to collect from its customers or others for customer-caused delays, errors in specifications and designs, contract terminations, change orders that are either in dispute or are unapproved as to both scope and price, or other causes of unanticipated additional contract costs.

In the event that customer requests a change of order (such as an upgrade of specifications, materials or additional work) before the completion of the project, the Group will negotiate and sign a subcontract with the customer, subject to mutual agreement. The subcontract has its own terms and conditions for the variable consideration and is generally integrated with the original master contract. This will normally result in an increase in additional billing to the customer and rarely a reduction in the total value of the contract. The effect of variable consideration on the transaction price of a performance obligation is recognized as an adjustment to revenue on a cumulative catch-up basis. To the extent unapproved change orders and claims reflected in transaction price (or excluded from transaction price in the case of liquidated damages) are not resolved in the Group's favor, or to the extent incentives reflected in transaction price are not earned, there could be reductions in, or reversals of, previously recognized revenue.

<u>Performance obligations satisfied at a point-in-time (Trading and manufacturing)</u>

For revenue recognized associated with its contracts with customers over time, for which the Group has an enforceable right to receive compensation. Many of our contracts contain specific provisions that determine when the Group can bill for its work performed under these contracts.

**NOTES TO CONSOLIDATED FINANCIAL STATEMENTSFOR THE YEARS ENDED DECEMBER 31, 2025, 2024 AND 2023**

Any costs incurred or any payment received for a long-term contract, for which revenue has not been recognized due to impracticability or inability to measure the performance obligation, is recorded as a contract asset and contract liability, respectively, on the Group's consolidated balance sheets. Revenue will be recognized when the performance obligation can be measured reliably and the criteria as stipulated under ACS 606 are met.

The Group's consolidated balance sheets present contract cost assets that represent our rights to receive payment for completed but not yet billed work and include costs incurred for contracts with customers as at financial year end less amounts received in advance from those customers at financial year end.

The Group's consolidated balance sheets present contract liabilities that contain deferred revenue that represent amounts received in advance from customers at financial year end in excess of any costs incurred on those contracts, which are in progress at year end, for which revenue has not yet been recognized.

Contract assets and contract liabilities arising from the same individual contract are presented net as either a single net contract asset or single net contract liability for presentation purposes.

· Research and development costs

Research and development costs ("R&D" costs) are expensed as incurred. The R&D costs amounted to approximately US$Nil, US$Nil and US$Nil for the years ended December 31, 2025, 2024 and 2023 respectively and were included in "Selling and administrative expenses" in the Group's consolidated statements of operations and comprehensive income / (loss).

· Advertising and promotional expenses

Advertising and promotional expenses ("A&P" expenses) are expensed as incurred. The A&P expenses amounted to approximately US$70,000, US$41,000 and US$29,000 for the years ended December 31, 2025, 2024 and 2023 respectively and were included in "Selling and administrative expenses" in the Group's consolidated statements of operations and comprehensive income / (loss).

· Income taxes

The Group follows the liability method of accounting for income tax. Under this method, deferred tax assets and liabilities are recorded for future tax consequences of temporary differences between the financial reporting and tax bases of assets and liabilities, and are measured using the enacted tax rates and laws that are expected to be in effect when the underlying assets or liabilities are recovered or settled. The Group also evaluates whether the recorded deferred tax assets and valuation allowances can be realized and, when necessary, reduces the amounts to what is expected to be realized.

The accounting guidance on accounting for uncertainty in income taxes also addresses derecognition, classification, interest and penalties on income taxes, and accounting in interim periods. The Group does not believe it has any uncertain tax positions through the periods ended December 31, 2025, 2024 and 2023 respectively which would have a material impact on the Group's consolidated financial statements.

Interest and penalties related to uncertain income tax positions are included in income tax expense on the Group's consolidated statements of operations and comprehensive income / (loss). Interest and penalties actually incurred are charged to interest expense and the other income, respectively if applicable.

The Group files tax returns in Hong Kong and the PRC. The tax returns for 2025, 2024 and 2023 are subject to examination by Hong Kong and PRC taxing authorities, commencing with the first year filed.

· Cash and cash equivalents

Cash and cash equivalents consist of cash on hand, and bank deposits with original maturities of three months or less, all of which are unrestricted as to withdrawal. There were no cash equivalents as of December 31, 2025 and 2024.

**NOTES TO CONSOLIDATED FINANCIAL STATEMENTS**

**FOR THE YEARS ENDED DECEMBER 31, 2025, 2024 AND 2023**

· Restricted cash

Restricted cash represents cash deposits retained with banks in the PRC for issuance of performance bonds and guarantees to the customers and cash deposited by the Group into separate accounts and designated as collateral for standby letters of credit in the same amount in accordance with contractual agreements.

· Accounts Receivable, net

The Group does not charge interest to its customers and carries its customer receivables at their face amounts net of expected credit losses. As is common practice in the industry, the Group classifies all accounts receivable as current assets.

The Group grants trade credit, on a non-collateralized basis, to its customers and is subject to potential credit risk related to changes in business and overall economic activity. The Group analyzes specific accounts receivable balances, historical bad debts, customer credit-worthiness, current economic trends and changes in customer payment terms when evaluating the adequacy of the allowance for doubtful accounts. In the event that a customer balance is deemed to be uncollectible, the account balance is written-off against the allowance for doubtful accounts.

· Inventories

Inventories are measured using the first-in, first-out method and are stated at the lower of cost or net realizable value. Cost of finished goods comprise direct material, direct production costs and an allocated portion of production overhead costs based on normal operating capacity. Allowance is made for obsolete, slow moving or defective items, where appropriate.

· Property, plant and equipment

Property, plant and equipment is carried at cost. Major modifications or refurbishments which extend the useful life of the assets are capitalized and depreciated over the adjusted remaining useful life of the assets. Upon retirement or disposition of property, plant and equipment, the cost and related accumulated depreciation are removed and any resulting gain or loss is recognized in consolidated income from operations. The cost of maintenance and repairs is charged to expense as incurred. Property, plant and equipment is reviewed for impairment and tested for recoverability whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. If the carrying value of property, plant and equipment exceeds its fair value, an impairment charge would be recorded in the consolidated statement of operations.

Depreciation of property, plant and equipment are computed using the straight-line method over the assets' estimated useful lives as follows:

---

| | |
|:---|:---|
|  | **Expected useful life** |
| Office premises | 47 to 51 years |
| Leasehold improvements  | Over terms of the leases or the useful lives whichever is less |
| Furniture, fixtures and office equipment | 3 to 5 years |
| Motor vehicles | 4 years |
| Testing equipment | 3 years |

---

· Impairment of long lived assets

Long-lived assets such as property, plant and equipment with finite lives are evaluated for impairment whenever events or changes in circumstances indicate that the carrying value of an asset may not be fully recoverable or that the useful life is shorter than the Group had originally estimated. When these events occur, the Group evaluates the impairment for the long-lived assets by comparing the carrying value of the assets to an estimate of future undiscounted cash flows expected to be generated from the use of the assets and their eventual disposition. If the sum of the expected future undiscounted cash flows is less than the carrying value of the assets, the Group recognizes an impairment loss based on the excess of the carrying value of the assets over the fair value of the assets. There was no impairment of long lived assets during 2025, 2024 and 2023, respectively.

· Long-term investment

The Group has elected to apply the measurement alternative to equity securities without readily determinable fair values. As such, the Group's non-marketable equity securities are measured at cost, less any impairment, and are adjusted for changes in fair value resulting from observable transactions for identical or similar investments of the investee.

· Leases arrangements

In the ordinary course of business, the Group enters into a variety of operating lease arrangements.

Operating right-of-use leases are included in operating lease right-of-use assets, current portion of long-term operating lease obligations and long-term operating lease obligations, net of current maturities on the Group's consolidated balance sheets, as appropriate. Operating lease right-of-use assets and operating lease liabilities are recognized based on the present value of the future minimum lease payments over the lease term at commencement date. As most of the Group's leases do not provide an implicit rate to calculate present value, the Group determines this rate by estimating the Group's incremental borrowing rate, utilizing the borrowing rates associated with the Group's various debt instruments. The operating lease right-of-use asset also includes any lease payments made and initial direct costs incurred and excludes lease incentives. Our lease terms may include options to extend or terminate the lease when it is reasonably certain that we will exercise that option.

Lease expense for minimum lease payments is recognized on a straight-line basis over the lease term.

· Goodwill

Goodwill is not amortized. The Group performs either a qualitative or quantitative assessment to review goodwill for impairment on an annual basis. This assessment is performed at the beginning of the fourth quarter, or when circumstances change, such as a significant adverse change in the business climate or the decision to sell a business, both of which would indicate that impairment may have occurred.

A qualitative assessment considers financial, industry, segment and macroeconomic factors, if the qualitative assessment indicates a potential for impairment, a quantitative assessment is performed to determine if impairment exists. The quantitative assessment begins with a comparison of the fair value of the reporting unit with its carrying value. If the carrying amount of the reporting unit exceeds its fair value, an impairment loss would be recognized in an amount equal to that excess, limited to the total amount of the goodwill allocated to the reporting unit. If the carrying value of goodwill exceeds its implied fair value, an impairment charge would be recorded in the consolidated statements of operations and comprehensive income / (loss).

As a result of the annual qualitative review process in 2025 and 2024, the Group determined it was not necessary to perform a quantitative assessment.

· Foreign currency translation

The assets and liabilities of the Group's subsidiaries denominated in currencies other than U.S. dollars are translated into U.S. dollars using the applicable exchange rates at the consolidated balance sheet date. For consolidated statements of operations and comprehensive income/(loss)' items, amounts denominated in currencies other than U.S. dollars were translated into U.S. dollars using the average exchange rate during the period. Equity accounts were translated at their historical exchange rates. Net gains and losses resulting from translation of foreign currency on consolidated financial statements are included in the consolidated statements of shareholders' equity as accumulated other comprehensive income. Foreign currency transaction gains and losses are reflected in the consolidated statements of operations and comprehensive income / (loss).

· Comprehensive income

We account for comprehensive income in accordance with ASC 220, "Comprehensive Income", which specifies the computation, presentation and disclosure requirements for comprehensive income. Comprehensive income consists of net income and foreign currency translation adjustments, primarily from fluctuations in foreign currency exchange rates of our foreign subsidiaries with a functional currency other than the U.S. dollar.

**FOR THE YEARS ENDED DECEMBER 31, 2025, 2024 AND 2023**

· Ordinary share

On November 22, 2011, the Company filed Amended and Restated Memorandum and Articles of Association with the Registry of Corporate Affairs of the BVI Financial Services Commission that on November 29, 2011 became effective as of the filing date to amend the Company's ordinary shares of US$0.01 par value capital stock to no par value capital stock. Treasury stock is accounted for using the cost method. When treasury stock is reissued, the value is computed and recorded using a weighted-average basis.

On October 8, 2019, the Company had stock split in the form of bonus shares at the rate of one ordinary share for every two ordinary shares held, creating 1,030,950 new shares of common stock.

On March 3, 2021, the Company had stock split in the form of bonus shares at the rate of two ordinary shares for every three ordinary shares held, creating 2,061,900 new shares of common stock.

The effect of the above stock splits have been reflected retroactively in the financial statements and net income per ordinary share computations.

· Net income per ordinary share

The Group computes net income per ordinary share using the treasury stock method. Under the treasury stock method, basic earnings per share attributable to Euro Tech Holdings Company Limited are computed by dividing net income attributable to Euro Tech Holdings Company Limited by the weighted average number of ordinary shares outstanding during the period. The Group reports both basic earnings per share, which is based on the weighted average number of ordinary shares outstanding, and diluted earnings per share, which is based on the weighted average number of ordinary shares outstanding and all dilutive potential ordinary shares outstanding.

Outstanding stock options are the only dilutive potential shares of the Company.

· Stock-based compensation

The Group determines compensation expense for stock-based awards based on the estimated fair values at the grant date and recognizes the related compensation expense over the vesting period. The Group uses the straight-line amortization method to recognize compensation expense related to stock-based awards that have only service conditions. This method recognizes stock compensation expense on a straight-line basis over the requisite service period for the entire award.

· Related parties

Related parties are affiliates of the Group; entities for which investments are accounted for by the equity method by the Group; trusts for the benefit of employees, such as pension and profit-sharing trusts that are managed by or under the trusteeship of management; principal owners of the Group; its management; members of the immediate families of principal owners of the Group and its management; and other parties with which the Group may deal if one party controls or can significantly influence the management or operating policies of the other to an extent that one of the transacting parties might be prevented from fully pursuing its own separate interests. Another party also is a related party if it can significantly influence the management or operating policies of the transacting parties or if it has an ownership interest in one of the transacting parties and can significantly influence the other to an extent that one or more of the transacting parties might be prevented from fully pursuing its own separate interests.

· Concentration

Financial instruments that potentially subject the Group to a concentration of credit risk consist principally of cash and cash equivalents and accounts receivable, net. The Group maintains substantially all of its cash and cash equivalent balances with large financial institutions which are believed to be high quality institutions.

The Group is subject to a concentration of risk because it derives a significant portion of its revenues from a few customers. The Group's top customers accounting for more than 5% of the Group's revenue generated approximately 48%, 47% and 41% of consolidated revenues for the years ended December 31, 2025, 2024 and 2023, respectively.

**NOTES TO CONSOLIDATED FINANCIAL STATEMENTS**

**FOR THE YEARS ENDED DECEMBER 31, 2025, 2024 AND 2023**

The Group grants trade credit under contractual payment terms, generally without collateral, to its customers, which include high credit quality electric utilities, general contractors, owners and managers of industrial properties and government departments.

Consequently, the Group is subject to potential credit risk related to changes in business and economic factors. At December 31, 2025, two (2024: Nil) of the Group's customers individually exceeded 10.0% of accounts receivable, net. The Group believes the terms and conditions in its contracts, billing and collection policies are adequate to minimize the potential credit risk.

· Finance costs

Interest relating to loans repaid is expensed in the period the repayment occurs.

· Warranties

The suppliers of the Group offer a standard one-year warranty to end customers of the Group. In certain contracts, a specific percentage is designated as warranty, and management has retained it as a "retainer fee" for potential warranty claims within an effective period subsequent to project completion. In the event that a warranty claim is made, the amount will be deducted from the retainer fee accordingly. This balance remains on the balance sheet in contract liabilities, until the expiration of the warranty period, after which it will be recognized as revenue if it has not been fully utilized. Historically, claims on warranties have been insignificant.

· Contract Assets and Contract Liabilities

Projects with performance obligations recognized over time that have revenue recognized to date in excess of cumulative billings are reported on consolidated balance sheets as "Contract assets". Provisions for estimated losses of contract assets on uncompleted contracts are made in the period in which such losses are determined.

Contract liabilities on uncompleted contracts are the amounts of cash collected from clients, billings to clients on contracts in advance of work performed and revenue recognized. The majority of these amounts are expected to be earned within 12 months and are classified as current liabilities.

· Shipping and handling costs

Amounts billed to customers related to shipping and handling are classified as revenues, and the Group's shipping and handling costs are included in cost of revenues.

· Retirement plan costs

Contributions to retirement plans (which are defined contribution plans) are charged to general and administrative expenses in the accompanying statements of operation as the related employee service are provided.

· Statutory reserves

The Group is required to make appropriation to reserve funds, comprising the statutory reserve fund and statutory staff welfare fund, based on after-tax net income determined with generally accepted accounting principles of the PRC ("PRC GAAP").

Appropriations to the statutory reserve fund is required to be at least 10% of the after tax net income determined in accordance with PRC GAAP until the reserve fund is equal to 50% of the entities' registered capital.

· Fair value measurements

The Company applies the provisions of ASC 820-10, "Fair Value Measurements", for fair value measurements of financial assets and financial liabilities and for fair value measurements of non-financial items that are recognized or disclosed at fair value in the financial statements.

**NOTES TO CONSOLIDATED FINANCIAL STATEMENTS**

**FOR THE YEARS ENDED DECEMBER 31, 2025, 2024 AND 2023**

The Group uses the three-tier hierarchy of fair value measurement, which prioritizes the inputs used in measuring fair value based upon their degree of availability in external active markets. These tiers include: Level 1 (the highest priority), defined as observable inputs, such as quoted prices in active markets; Level 2, defined as inputs other than quoted prices in active markets that are either directly or indirectly observable; and Level 3 (the lowest priority), defined as unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions.

As of December 31, 2025 and 2024, the Group determined that the carrying values of cash and cash equivalents, restricted cash, accounts receivable, net, prepayments and other current assets, contract assets, bank borrowings, accounts payable, contract liabilities, other payables and accrued expenses approximate their fair values because of the short-term nature of these instruments. The Group has also determined that the fair value of non-controlling interest - put option is immaterial as of December 31, 2025, and is immaterial for 2024.

· Recent accounting pronouncements

Changes to GAAP are typically established by the Financial Accounting Standards Board ("FASB") in the form of accounting standards updates ("ASUs") to the FASB's ASC. The Group considers the applicability and impact of all ASUs. The Group, based on its assessment, determined that any recently issued or proposed ASUs not listed below are either not applicable to the Group or may have minimal impact on its consolidated financial statements.

**Recently adopted accounting pronouncements**

In September 2022, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update (ASU) No. 2022-04 that requires additional qualitative and quantitative disclosures surrounding supplier finance programs intended to help investors better consider the effect of these programs on a company's working capital, liquidity, and cash flows over time. This update is effective for fiscal years beginning after December 15, 2022, including interim periods, except for the disclosure of roll forward information, which is effective for fiscal years beginning after December 15, 2023. Early adoption is permitted. The Company adopted this ASU on October 1, 2023, and it did not have a significant impact on our CFS.

In June 2022, the FASB issued ASU 2022-03 Fair Value Measurement (Topic 820): Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions ("ASU 2022-03"), which (1) clarifies the guidance in ASC 820 on the FV measurement of an equity security that is subject to a contractual sale restriction and (2) requires specific disclosures related to such an equity security. Under current guidance, stakeholders have observed diversity in practice related to whether contractual sale restrictions should be considered in the measurement of the FV of equity securities that are subject to such restrictions. To reduce the diversity in practice and increase the comparability of reported financial information, ASU 2022-03 clarifies this guidance and amends the illustrative example. ASU No. 2022-03 is effective for fiscal years beginning after December 15, 2023, with early adoption permitted. The Company is currently evaluating the extent of the impact of this ASU but does not expect the adoption of this standard to have a significant impact on our CFS.

In March 2022, the FASB issued ASU No. 2022-02, Troubled Debt Restructurings and Vintage Disclosures. ASU 2022-02 eliminates the accounting guidance on troubled debt restructurings for creditors in ASC Topic 310 and amends the guidance on "vintage disclosures" to require disclosure of current-period gross write-offs by year of origination. ASU 2022-02 also updates the requirements for accounting for credit losses under ASC Topic 326 and adds enhanced disclosures for creditors with respect to loan re-financings and restructurings for borrowers experiencing financial difficulty. ASU 2022-02 is effective for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years. The Company adopted this ASU on October 1, 2023, and it did not have a significant impact on our CFS.

In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments — Credit Losses, which changes the accounting for recognizing impairments of financial assets. Under the new guidance, credit losses for certain types of financial instruments will be estimated based on expected losses. The new guidance also modifies the impairment models for available-for-sale debt securities and for purchased financial assets with credit deterioration since their origination.

**NOTES TO CONSOLIDATED FINANCIAL STATEMENTS**

**FOR THE YEARS ENDED DECEMBER 31, 2025, 2024 AND 2023**

In March 2020, the FASB issued ASU No. 2020-04 providing optional expedients and exceptions to account for the effects of reference rate reform to contracts, hedging relationships, and other transactions that reference LIBOR or another reference rate expected to be discontinued. The optional guidance, which became effective March 12, 2020, could be applied through December 31, 2022. In December 2022, the FASB issued No 2022-06 extending the sunset date of the relief provided under ASU No. 2020-04 to December 31, 2024. The Company has various contracts that reference LIBOR and is assessing how this standard may be applied to specific contract modifications through March 31, 2025.

On March 28, 2023, the FASB issued ASU No. 2023-01, Leases (Topic 842): Common Control Arrangements. ASU 2023-01 is designed to clarify the accounting for leasehold improvements associated with common control leases, thereby reducing diversity in practice. The new standard was effective for the Company for its fiscal year beginning October 1, 2023, with early adoption permitted. The Company is currently evaluating the impact of adopting the standard on its CFS.

**Recently issued accounting pronouncements not yet adopted** 

In November 2023, the FASB issued ASU 2023-07, "Segment Reporting (Topic 280)" ("ASU 2023-07"). The amendments in ASU 2023-07 improve financial reporting by requiring disclosure of incremental segment information on an annual and interim basis for all public entities to enable investors to develop more decision useful financial analyses. Topic 280 requires a public entity to report a measure of segment profit or loss that the chief operating decision maker (CODM) uses to assess segment performance and make decisions about allocating resources. Topic 280 also requires other specified segment items and amounts, such as depreciation, amortization, and depletion expense, to be disclosed under certain circumstances. The amendments in ASU 202307 do not change or remove those disclosure requirements. The amendments in ASU 2023-07 also do not change how a public entity identifies its operating segments, aggregates those operating segments, or applies the quantitative thresholds to determine its reportable segments. The amendments in ASU 2023-07 are effective for years beginning after December 15, 2023 and interim periods within fiscal years beginning after December 15, 2024, adopted retroactively. Management expect the guidance will not have a significant impact on our CFS.

In December 2023, the FASB issued ASU 2023-09, Improvement to Income Tax Disclosure. This standard requires more transparency about income tax information through improvements to income tax disclosures primarily related to the rate reconciliation and income taxes paid information. This standard also includes certain other amendments to improve the effectiveness of income tax disclosures. ASU 2023-09 is effective for public business entities, for annual periods beginning after December 15, 2024. For entities other than public business entities, the amendments are effective for annual periods beginning after December 15, 2025. The Company is in the process of evaluation the impact of adopting this new guidance on our CFS.

In December 2025, the FASB issued ASU 2025-11 to amend the guidance in "Interim Reporting" (Topic 270). The update provides clarifications intended to improve the consistency and usability of interim disclosure requirements, including a comprehensive listing of required interim disclosures and a new disclosure principle for reporting material events occurring after the most recent annual period. The amendments do not change the underlying objectives of interim reporting but are designed to enhance clarity in application. The ASU is effective for fiscal years beginning after December 15, 2027, and interim periods within those fiscal years. Management is currently evaluating the effects impact that the adoption of this update may have on its financial statements.

The Group has reviewed all recently issued, but not yet effective, accounting pronouncements and does not believe the future adoption of any such pronouncements may be expected to cause a material impact on its financial condition or the results of its operations.

· Reclassification

Certain reclassifications have been made to prior year amounts to conform with the current year presentation.

**Note 3: Segment information**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) The Group reports under two segments: Trading and manufacturing, and Engineering.

Operating income represents total revenues less operating expenses, excluding other expense, interest and income taxes. The identifiable assets by segment are those used in each segment's operations. Intersegment transactions are not significant and have been eliminated to arrive at consolidated totals.

**Note 6: Contract assets and liabilities**

**Note 10 : Goodwill**

Reporting units - The Group's reporting units consist of its trading and manufacturing and engineering segments. Goodwill is not amortized, but instead is reviewed for impairment at least annually during the fourth quarter of each year at the reporting level, absent any interim indicators of impairment or other factors requiring an assessment.

Annual impairment assessment - For our 2025 and 2024 annual impairment test we performed a qualitative assessment, using information as of December 31, 2025 and 2024, respectively. Under current guidance, we are permitted to first assess qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount as a basis for determining whether it is necessary to perform a quantitative goodwill impairment test. We determined there were no factors indicating the need to perform a quantitative goodwill impairment test and concluded that it is more likely than not the fair value of our reporting units is greater than their carrying value and thus there was no impairment to goodwill.

In addition to our annual review, we assess the impairment of goodwill whenever events or changes in circumstances indicate that the carrying value of a reporting unit may be greater than fair value. Factors that could trigger an interim impairment review include, but are not limited to, significant adverse changes in the business climate which may be indicated by a decline in our market capitalization or decline in operating results. No impairments were recorded to our goodwill during the years ended December 31, 2025, 2024 and 2023. No material events or changes occurred between the testing date and year end to trigger a subsequent impairment review.

At December 31, 2025 and 2024, we had goodwill for our engineering segment with a carrying amount of US$1,071,000 and US$1,071,000, respectively.

The Plan provides for the granting of up to 300,000 (500,000 after bonus shares adjustment) Ordinary Shares (the "Share Limit"), in the form of options to Officers, Directors and Key Employees who perform services which contribute to the successful performance of the Company and its subsidiaries. In addition, the Plan provides that, on the first day of each fiscal year commencing on January 1, 2020, the Share Limit shall automatically be increased by that number of shares equal to 5% of the number of Ordinary Shares outstanding as of such date. The Board of Directors or a committee (the "Committee") appointed by the Board of Directors administers the Plan.

Appropriate adjustment in the maximum number of Ordinary Shares issuable pursuant to this Plan, the maximum number of Ordinary Shares with respect to which options may be granted within any 12-month period to any participant during the duration of this Plan, the number of shares subject to options granted under this Plan, and the exercise price with respect to options, shall be made to give effect to any increase or decrease in the number of issued Ordinary Shares resulting from a subdivision or consolidation of shares whether through reorganization, recapitalization, division of shares, reverse share split, spin-off, split-off, spin-out, or other distribution of assets to shareholders, issue of bonus shares or combination of shares, assumption and conversion of outstanding options due to an acquisition by the Company of the shares, stock or assets of any other company or corporation, other increase or decrease in the number of such shares outstanding effected, without receipt of consideration by the Company, or any other occurrence for which the Committee determines an adjustment is appropriate.

The purchase price per share of the Ordinary Shares to be paid upon the exercise of the option must be at least 100% of the fair market value of an Ordinary Shares on the date on which the option was granted. Under the Plan, if the Ordinary Shares are principally traded on a national securities exchange or the Nasdaq Global Market or Capital Market at the time of grant, the Company is required to use, at fair market value, the average of the closing prices of the Ordinary Shares for the ten consecutive trading days immediately before the date of grant. If the Ordinary Shares are traded on a national securities exchange or the Nasdaq Stock Global Market or Capital Market, but no closing prices are reported for such ten-day period, or if the Ordinary Shares are principally traded in the over-the-counter market, the Company is required to use, as fair market value, the average of the mean between the bid and asked prices reported for the Company's Ordinary Shares at the close of trading during such ten-day period before the date of grant. If the Ordinary Shares are traded neither on a national securities exchange, one of the Nasdaq's Markets nor in the over-the-counter market or if bid and asked prices are otherwise not available, the fair market value of the Ordinary Shares on the date of grant will be determined in good faith by the Committee or the Board of Directors, as the case may be.

The Board of Directors or the Committee, as the case may be, determines, at the time of grant, when each option granted under the Plan will become exercisable. Notwithstanding the foregoing, all options held by a key employee of the Company or its subsidiaries become immediately exercisable, whether or not exercisable at the time, upon the death or disability, and shall be exercisable within twelve (12) months after the date of death or disability, but in no event later than the expiration date of such Options.

During the year ended December 31, 2022, the Company granted such options to its officers, directors and employees, which allow them to purchase up to 80,000 ordinary shares. The exercise price of all options granted is US$2.80 per share. The stock options granted are exercisable on April 1, 2024 and terminate on April 18, 2029.

As of December 31, 2025 and 2024, there was no unrecognized stock-based compensation expense related to unvested stock options. The compensation expense for the year is Nil (2024: US$12,000 and 2023: US$47,000).

The Group applies the provisions of ASC 718-10, which requires to recognise expense related to the fair value of stock-based compensation awards, including employee stock options.

The Binomial option-pricing model is used to estimate the fair value of the options granted. This requires the input of subjective assumptions, including the expected volatility of stock price, expected option term, expected risk-free rate over the expected option term and expected dividend yield rate over the expected option term. Because changes in subjective input assumptions can materially affect the fair value estimate, in directors' opinion, the existing model may not necessarily provide a realisable measure of the fair value of the stock options. Expected volatility is based on historical volatility in the 180 days prior to the issue of the options. Expected option term and dividend yield rate are based on historical trends. Expected risk-free rate is based on US Treasury securities with similar maturities as the expected terms of the options at the date of grant.

**Note 20 : Pension plan**

Prior to December 1, 2000, Far East had only one defined contribution pension plan for all its Hong Kong employees. Under this plan, all employees were entitled to pension benefits equal to their own contributions plus 50% to 100% of individual fund account balances contributed by Far East, depending on their years of service with Far East. Far East was required to make specific contributions at approximately 10% of the basic salaries of the employees to an independent fund management company.

With the introduction of the Mandatory Provident Fund Scheme ("MPF scheme"), a defined contribution scheme managed by an independent trustee on December 1, 2000, Far East and its employees who joined Far East subsequently make monthly contributions to the scheme at 5% of the employee's cash income as defined under the Mandatory Provident Fund Schemes Ordinance. Under the MPF scheme, the employer and its employees are each required to make contributions to the plan at 5% of the employees' relevant income, subject to a cap of monthly relevant income of HK$30,000. Contributions to the plan vest immediately.

During the years ended December 31, 2025, 2024 and 2023, the aggregate contributions of the Group to the aforementioned pension plans and retirement benefit schemes were approximately US$186,000, US$191,000 and US$192,000, respectively.

**FOR THE YEARS ENDED DECEMBER 31, 2025, 2024 AND 2023**

As stipulated by the rules and regulations in the PRC, the PRC's subsidiaries contributes to state-sponsored retirement plans for its employees in Mainland China. PRC's subsidiaries' contribution approximately 16% of the basic salaries of its employees, and have no further obligations for the actual payment of pension or post-retirement benefits beyond the annual contributions. The state-sponsored retirement plans are responsible for the entire pension obligations payable to retired employees.

**Note 21 : Risk factors**

Financial risk factors

The Group's activities expose it to a variety of financial risks: credit risk and foreign exchange rate risk.

(i) Credit risk

The Group has no significant concentration of credit risk, cash in banks in Hong Kong and PRC is insured with limit of approximately US$102,000 and US$71,000, respectively per bank per each depositor. Uninsured cash in banks and restricted cash balances in Hong Kong and PRC are of approximately US$5,174,000 (2024: US$5,251,000). Cash transactions are limited to high credit quality banks.

(ii) Foreign exchange rate risk

The Group operates in Hong Kong, the PRC and trades with both local and overseas customers and suppliers, and is exposed to foreign exchange rate risk arising from various currency exposures, primarily with respect to purchases in Hong Kong dollars, Renminbi and Euros. Foreign exchange risk arises from committed and unmatched future commercial transactions, such as confirmed import purchase orders and sales orders, recognized assets and liabilities, and net investment in the PRC operations.

**Note 22 : Risk and uncertainty**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) Property title in the PRC

The Group, through its subsidiary, Far East received total rental income of US$7,000 in 2025 on a property in Beijing, China pursuant to relevant lease agreement from 2025 to 2027.The latest lease agreement has been terminated in December 2025. The Group made payment for the purchase of such property, but has not successfully obtained Certificate of Real Estate Ownership or title of such property from the PRC authority. The property's book value as at December 31, 2025 was approximately US$71,000. Far East has made an effort to request the developer of the property to assist with obtaining the title, but those efforts have failed. Far East is still investigating various ways to obtain the title but has not formulated a specific plan as of the date of this Annual Report.

In connection with the above, if the property is to be disposed, it is likely that Far East's title to the property will be challenged, and in such case the Group will need to incur additional costs and expenses to confirm and defend its title to the property and the rental income it has collected. There is no assurance that Far East will succeed in its efforts to obtain the title to the property and the rental income it has collected. Far East's failure in this regard could have material adverse effect on the Group's financial position, results of operations, and cash flow.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) Non-controlling interest Put Option

The Group granted the non-controlling interest of Yixing Pact Environmental Technology Co., Ltd. and Pact Asia Pacific Limited a put option, which is effective from 2009, requiring the Group to acquire part or all remaining shares of these two companies at a purchase price per share calculated by 5.2 times of their average net income for the three prior fiscal years divided by total number of shares outstanding at the time of exercise of such option. Such put option did not have an expiry date. The management of the Group has conducted an assessment of the fair value of the put option and determined it to be immaterial. The fair value assessment of the put option involves significant judgment and estimation, the management's reliance on internal expertise for the fair value assessment may introduce inherent uncertainties and potential for subjectivity.

 **Note 24 : Commitments and contingencies** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) Banking facilities

As at December 31, 2025 and 2024, the Group had various banking facilities available for overdraft and import and export credits from which the Group can draw up to approximately US$897,000 and US$897,000 respectively, of which approximately US$72,000 and US$183,000 were utilised for issuance of bank guarantees as security for the performance of various contracts with customers and import loans. The various banking facilities are secured by a bank deposit of approximately US$897,000 and various blanket counter indemnities and counter indemnities. The Group undertakes to maintain its tangible net worth not at any time less than approximately US$3,846,000 and was in compliance with the covenant.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) Non-controlling interest put option

The Group granted the non-controlling interest of Yixing Pact Environmental Technology Co., Ltd. and Pact Asia Pacific Limited a put option, which is effective from 2009, requiring the Group to acquire part or all remaining shares of these two companies at a purchase price per share calculated by 5.2 times of their average net income for the three prior fiscal years divided by total number of shares outstanding at the time of exercise of such option. Such put option did not have an expiry date. Based on the analysis under ASC 820 " Fair Value Measurement" , Level 3 inputs: unobservable inputs that are supported by little or no market ability, management of the Group has conducted an assessment of the fair value of the put option, refer below. The fair value assessment of the put option involves significant judgment and estimation, the management's reliance on internal expertise for the fair value assessment may introduce inherent uncertainties and potential for subjectivity.

The valuation technique used to determine the fair value of the put option was the Options Pricing Model (OPM).

The following inputs and assumptions were used in determining the fair value of the put options:

---

| |
|:---|
| Median price to earnings ratio of similar companies of 23,965 (Range 4, 7288 to 36, 7237) |
| Median discount for lack of marketability 15.7% (Range 8.4% to 28.7%) |
| Mean Annualized volatility of return of the underlying share for similar companies of 102.39% (Range 36.025 to 349.944) |
| The average life of a company is around 21 years according to research (<u>www.statista.com/statistics/1259275/average-company-lifespan</u>) thus an assumption on the life of the options was set as 20 years. |
| A dividend yield rate of 0% was used |
| For Yixing Pact Environmental Technology Co. Ltd, the China risk-free rate of 2.698% was used based on a tenor of 20 years (source- Bloomberg) |
| For Pact Asia Pacific Limited, the USD risk-free rate of 3.954% was used based on a tenor of 20 years (source- Bloomberg) |

---

The resultant strike price of the options was valued at $0 per share and the fair value of the options was valued at $0 as at 31 December 2025.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii) Insurance

The Group carries insurance policies to cover various risks, primarily general liability, automobile liability, workers' compensation and employee medical expenses under which we are liable to reimburse the insurance company for a portion of each claim paid.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iv) Purchase commitments

To manage the risk of changes in material prices and subcontracting costs used in tendering bids for engineering contracts, most of the time, the Group obtains firm quotations from suppliers and subcontractors before submitting a bid. These quotations do not include any quantity guarantees. As soon as the Group is advised that its bid is successful, the Group enters into firm contracts with most of its materials suppliers and sub-contractors, thereby mitigating the risk of future price variations affecting the contract costs.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(v) Litigations

The Group is now and may in the future be involved as a party to various legal proceedings that are incidental to the ordinary course of business. Management, after consultation with legal counsel, does not believe that the outcome of these actions will have a material impact on the consolidated financial statements of the Group. There are no significant unresolved legal issues as of December 31, 2025 and 2024.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(vi) Contingencies

The Group accounts for loss contingencies in accordance with ASC 450 and other related guidelines. As of December 31, 2025 and 2024, the Group's management is of the opinion that there are no commitments and contingencies to account for.

**Note 25: Subsequent event** 

On March 3, 2026, the Company approved a share repurchase program to repurchase up to 250,000 ordinary shares, for an aggregate purchase price of not more than US$350,000 over a period of one year.

In accordance with ASC 855, "*Subsequent Events*", which establishes general standards of accounting for and disclosure of events that occur after the balance sheet date but before consolidated financial statements are issued, the Company evaluated all events and transactions that occurred after December 31, 2025, up through the date the Company issued the audited consolidated financial statements. Other than the event disclosed above, there was no other subsequent events occurred that would require recognition or disclosure in the Company's audited consolidated financial statements.

**REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM**

To: The Board of Directors and Shareholders of Zhejiang Tianlan Environmental Protection Technology Company Limited

**Opinion on the Financial Statements**

We have audited the accompanying consolidated balance sheets of Zhejiang Tianlan Environmental Protection Technology Company Limited (the "Company") and its subsidiaries (the "Group") as of December 31, 2025 and 2024, and the related consolidated statements of operations and comprehensive income, consolidated statement of changes in shareholders' equity, and consolidated statements of cash flows for each of the three years in the period ended December 31, 2025, and the related notes to the consolidated financial statements and schedule (collectively referred to as the "financial statements"). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Group as of December 31, 2025 and 2024, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2025, in conformity with accounting principles generally accepted in the United States of America.

**Basis for Opinion**

These financial statements are the responsibility of the Group's management. Our responsibility is to express an opinion on the Group's financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) ("PCAOB") and are required to be independent with respect to the Group in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Group is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits, we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Group's internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

**Critical Audit Matters** 

Critical audit matters are matters arising from the current year audit of the financial statements that were communicated or are required to be communicated to the audit committee and that: (1) relate to accounts or disclosures that are material to the financial statements, and (2) involved especially challenging, subjective, or complex judgments.

The communication of critical audit matters does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matters below, providing separate opinions on the critical audit matters or on the accounts or disclosures to which they relate.

*Revenue Recognition – Contracts recognised over time*

As described in Note 2 to the consolidated financial statements, the Group adopted Accounting Standards Codification (ASC) Topic 606, Revenue from Contracts with Customers. Under this standard, the Group recognizes revenue over time, reflecting the continuous transfer of control of goods or services to the customer. Revenue is measured using the input method. The Group generally measures its progress to completion using an input measure of total costs incurred divided by total costs expected to be incurred.

We identified revenue recognition using the input method as a critical audit matter due to the significant judgments involved in determining the timing and amount of revenue recognized. These judgments include assessing the accuracy of the budgeted cost. Budgeted cost can vary, sometimes substantially, from substantially, from previous estimates due to changes in a variety of factors, including unforeseen or changed circumstances not included in management's cost estimates. The complexity and subjectivity associated with these assessments required extensive audit effort and a high degree of auditor judgment.

Our key consideration is our evaluation of revenue recognition involves assessing the appropriateness of the Group's application of ASC 606, including the identification and measurement of performance obligations, the determination of the stages of works certified by customers, and the classification of contract assets and liabilities. Our audit procedures to assess the above include:

1. Understand and evaluate the Group's revenue recognition policies and procedures including the adoption and application of ASC 606;

2. Evaluate the identification and measurement of performance obligations, including the Group's determination of whether they are distinct or combined;

3. Assess the methodology used to measure progress towards complete satisfaction of performance obligations over time, including the use of the input method;

4. Verify and review the classification and accuracy of contract assets and liabilities;

5. Test samples of cost to invoices to verify the actual cost incurred during the financial year;

6. Validate invoices billed to customers subsequent to financial year end for revenue earned as at financial year end and validate receipt of payments for these invoices.

7. Reperformed the calculation of the revenue based on the percentage of completion method and where applicable, considered the implications of any changes in estimates.;

8. Assess the adequacy of the Group's disclosures related to revenue recognition under ASC 606.

**NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS (CONT'D)**

**2.** **Summary of significant accounting policies (Cont'd)**

**(d)** **Revenue recognition (Cont'd)**

<u>Performance obligations satisfied over time (Design, installation and operation management services)</u>

Recognition of performance obligations

A performance obligation is a promise in a contract to transfer a distinct good or service to the customer, and is the unit of account in the new revenue standard. The contract transaction price is allocated to each distinct performance obligation and recognized as revenue when, or as, the performance obligation is satisfied. Engineering projects typically span between 12 to 36 months. The majority of our contracts have a single performance obligation as the promise to transfer the individual goods or services is not separately identifiable from other promises in the contracts and, therefore, not distinct. Some contracts have multiple performance obligations, most commonly due to the contract covering multiple phases of the project life cycle (design, installation and operation management services).

Revenues are recognized as our obligations are satisfied over time, using the ratio of project costs incurred to estimated total costs for each contract because of the continuous transfer of control to the customer as all of the work is performed at the customer's site and, therefore, the customer controls the asset as it is being installed. This continuous transfer of control to the customer is further supported by clauses in the contract that allow the customer to unilaterally terminate the contract for convenience, pay the Group for costs incurred plus a reasonable profit and take control of any work in process. This cost-to-cost measure is used because management considers it to be the best available measure of progress on these contracts. Contract costs include all direct material, labor, subcontract and other costs.

Items excluded from cost-to-cost

Pre-contract costs are generally not material and are charged to expense as incurred, but in certain cases pre-contract recognition may be deferred if specific probability criteria are met.

Variable consideration

Contract modifications through change orders, claims and incentives are routine in the performance of the Group's contracts to account for changes in the contract specifications or requirements. In most instances, contract modifications are not distinct from the existing contract due to the significant integration of services provided in the contract and are accounted for as a modification of the existing contract and performance obligation. Either the Group or its customers may initiate change orders, which may include changes in specifications or designs, manner of performance, facilities, equipment, materials, sites and period of completion of the work. Change orders that are unapproved as to both price and scope are evaluated as claims. The Group considers claims to be amounts in excess of approved contract prices that the Group seeks to collect from its customers or others for customer-caused delays, errors in specifications and designs, contract terminations, change orders that are either in dispute or are unapproved as to both scope and price, or other causes of unanticipated additional contract costs.

**ZHEJIANG TIANLAN ENVIRONMENTAL PROTECTION TECHNOLOGY COMPANY LIMITED**

**NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS (CONT'D)**

**2.** **Summary of significant accounting policies (Cont'd)** 

**(d)** **Revenue recognition (Cont'd)**

The Group estimates variable consideration for a performance obligation at the most likely amount to which the Group expects to be entitled (or the most likely amount the Group expects to incur in the case of liquidated damages), utilizing estimation methods that best predict the amount of consideration to which the Group will be entitled (or will incur in the case of liquidated damages). The Group includes variable consideration in the estimated transaction price to the extent it is probable that a significant reversal of cumulative revenue recognized will not occur or when the uncertainty associated with the variable consideration is resolved. The Group's estimates of variable consideration and determination of whether to include estimated amounts in transaction price are based largely on an assessment of its anticipated performance and all information (historical, current and forecasted) that is reasonably available to the Group.

The effect of variable consideration on the transaction price of a performance obligation is recognized as an adjustment to revenue on a cumulative catch-up basis. To the extent unapproved change orders and claims reflected in transaction price (or excluded from transaction price in the case of liquidated damages) are not resolved in the Group's favor, or to the extent incentives reflected in transaction price are not earned, there could be reductions in, or reversals of, previously recognized revenue.

**(e)** **Research and development costs**

Research and development costs ("R&D" costs) are expensed as incurred. The R&D costs amounted to approximately RMB22,049,000, RMB27,371,000 and RMB20,452,000 for the years ended December 31, 2025, 2024 and 2023 respectively and were included in "Selling and administrative expenses" in the Group's consolidated statements of operations.

**(f)** **Income tax** 

The Group follows the liability method of accounting for income tax. Under this method, deferred tax assets and liabilities are recorded for future tax consequences of temporary differences between the financial reporting and tax bases of assets and liabilities, and are measured using the enacted tax rates and laws that are expected to be in effect when the underlying assets or liabilities are recovered or settled. The Group also evaluates whether the recorded deferred tax assets and valuation allowances can be realized and, when necessary, reduces the amounts to what is expected to be realized.

The accounting guidance on accounting for uncertainty in income taxes also addresses derecognition, classification, interest and penalties on income taxes, and accounting in interim periods. The Group does not believe it has any uncertain tax positions through the periods ended December 31, 2025, 2024 and 2023 respectively which would have a material impact on the Group's consolidated financial statements.

The Group files tax returns in the PRC. The tax returns for 2025, 2024 and 2023 are subject to examination by the PRC taxing authorities, commencing with the first year filed.

**NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS (CONT'D)**

**2.** **Summary of significant accounting policies (Cont'd)** 

**(g)** **Cash and cash equivalents**

Cash and cash equivalents consist of bank deposits with original maturities of three months or less, all of which are unrestricted as to withdrawal and uninsured. There were no cash equivalents as of December 31, 2025 and 2024.

**(h)** **Accounts receivable and allowance for doubtful accounts** 

The Group does not charge interest to its customers and carries its customer receivables at their face amounts, less an allowance for doubtful accounts. As is common practice in the industry, the Group classifies all accounts receivable as current assets.

The Group grants trade credit, on a non-collateralized basis, to its customers and is subject to potential credit risk related to changes in business and overall economic activity. The Group analyzes specific accounts receivable balances, historical bad debts, customer credit-worthiness, current economic trends and changes in customer payment terms when evaluating the adequacy of the allowance for doubtful accounts. In the event that a customer balance is deemed to be uncollectible, the account balance is written-off against the allowance for doubtful accounts.

**(i)** **Classification of contract assets, net and liabilities** 

For revenue recognized associated with its contracts with customers over time, for which the Group has an enforceable right to receive compensation. Many of our contracts contain specific provisions that determine when the Group can bill for its work performed under these contracts.

Any revenue earned on a contract that has not yet been billed to the customer is recorded as a contract asset on the Group's consolidated balance sheets.

The Group's consolidated balance sheets present contract liabilities that contain deferred revenue that represent any costs incurred on contracts in process for which revenue has not yet been recognized.

**(j)** **Inventories**

Inventories are measured using the weighted average method and are stated at the lower of cost or net realizable value. Cost of finished goods comprise direct material, direct production costs and an allocated portion of production overhead costs based on normal operating capacity.

**(k)** **Property, plant and equipment and land use right, net**

Property, plant and equipment is carried at cost. Major modifications or refurbishments which extend the useful life of the assets are capitalized and depreciated over the adjusted remaining useful life of the assets. Upon retirement or disposition of property, plant and equipment, the cost and related accumulated depreciation are removed and any resulting gain or loss is recognized in consolidated income from operations. The cost of maintenance and repairs is charged to expense as incurred. Property, plant and equipment is reviewed for impairment and tested for recoverability whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. If the carrying value of property, plant and equipment exceeds its fair value, an impairment charge would be recorded in the consolidated statement of operations.

**NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS (CONT'D)**

**2.** **Summary of significant accounting policies (Cont'd)** 

**(k)** **Property, plant and equipment and land use right, net (Cont'd)**

Land in the PRC is owned by the PRC government. The government in the PRC, according to PRC Law, may sell the right to use the land for a specific period of time. Thus, all of the Group's land purchases in the PRC are considered to be leasehold land and are classified as land use right.

Depreciation of property, plant and equipment and amortization of land use right are computed using the straight-line method over the assets' estimated useful lives as follows:

---

| | |
|:---|:---|
| Land use right | Over terms of the leases |
| Buildings and leasehold improvements | 11 to 50 years, with 5% residual value |
| Furniture, fixtures and office equipment | 5 years, with 5% residual value |
| Motor vehicles | 5 years, with 5% residual value |
| Plant and machineries | 5 to 10 years, with 5% residual value |

---

---

| | |
|:---|:---|
| **(l)**  | **Intangible assets, net** |
|  | The Group is currently amortizing its acquired intangible assets, consisted of patents and others, with finite-lived over periods generally ranging between three to twenty years. |

---

**(m)** **Impairment of long lived assets**

Long-lived assets such as property, plant and equipment and intangible assets with finite lives are evaluated for impairment whenever events or changes in circumstances indicate that the carrying value of an asset may not be fully recoverable or that the useful life is shorter than the Group had originally estimated. When these events occur, the Group evaluates the impairment for the long-lived assets by comparing the carrying value of the assets to an estimate of future undiscounted cash flows expected to be generated from the use of the assets and their eventual disposition. If the sum of the expected future undiscounted cash flows is less than the carrying value of the assets, the Group recognizes an impairment loss based on the excess of the carrying value of the assets over the fair value of the assets. The impairment of long-lived assets amounted to approximately RMB Nil, RMB Nil and RMB Nil for the years ended December 31, 2025, 2024 and 2023 respectively and were included in "Selling and administrative expenses" in the Group's consolidated statements of operations.

**(n)** **Government grant income**

Government grant income consists of receipt of funds to subsidize the investment cost of technical development in China. No present or future obligation arises from the receipt of such amount.

Government grants are recognized in the consolidated balance sheet initially when there is reasonable assurance that they will be received and that the Group will comply with the conditions attaching to them. Grants that compensate the Group for expenses incurred are recognized as income in the consolidated statement of operations on a systematic basis in the same periods in which the expenses are incurred. Grants that compensate the Group for the cost of an asset are deducted from the carrying amount of the asset and consequently are effectively recognized in the consolidated statements of operations over the useful life of the asset by way of reduced depreciation expenses.

**NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS (CONT'D)**

**2.** **Summary of significant accounting policies (Cont'd)** 

**(o)** **Leases arrangements** 

The Group adopted ASU No. 2016-02, Leases (Topic 842). The Group leases certain equipment under finance leases. The economic substance of the leases is a financing transaction for acquisition of the equipment. Accordingly, the right-of-use assets for these leases are included on the Group's consolidated balance sheets in property, plant and equipment, net of accumulated depreciation, amortization and impairment losses, with a corresponding amount recorded in current portion of long-term finance lease obligations. The finance lease assets are amortized over the life of the lease or, if shorter, the life of the leased asset, on a straight-line basis and included in depreciation expense. The financing component associated with finance lease obligations is included in interest expense. Generally, for the Group's finance leases an implicit rate to calculate present value is provided in the lease agreement, however if a rate in not provided the Group determines this rate by estimating the Group's incremental borrowing rate, utilizing the borrowing rates associated with the Group's various debt instruments.

The Group determines if an arrangement is a lease at inception. Lease liabilities are the Group's obligation to make lease payments arising from a lease and are measured on a discounted basis.

**(p)** **Share capital**

Paid in capital refers to the registered capital paid up by the shareholders of the Company.

At December 31, 2025, there were 82,572,000 shares (2024: 82,572,000 shares) issued.

**(q)** **Use of estimates**

The preparation of the accompanying consolidated financial statements in conformity with GAAP requires management to make estimates and judgments that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Certain accounting estimates of the Group require a higher degree of judgment than others in their application. These include the recognition of revenue and earnings from contracts over time, contract assets, net and contract liabilities. Management continually evaluates all of its estimates and judgments based on available information and experience; however, actual results could differ from these estimates.

**(r)** **Related parties**

Entities are considered to be related to the Group if the parties, directly or indirectly, through one or more intermediaries, control, are controlled by, or are under common control with the Group. Related parties also include principal owners of the Group, its management, members of the immediate families of principal owners of the Group and its management and other parties with which the Group may deal if one party controls or can significantly influence the management or operating policies of the other to an extent that one of the transacting parties might be prevented from fully pursuing its own separate interests. A party which can significantly influence the management or operating policies of the transacting parties or if it has an ownership interest in one of the transacting parties and can significantly influence the other to an extent that one or more of the transacting parties might be prevented from fully pursuing its own separate interests is also a related party.

**NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS (CONT'D)**

**2.** **Summary of significant accounting policies (Cont'd)** 

**(s)** **Net income per ordinary share**

The Group computes net income per ordinary share using the treasury stock method. Under the treasury stock method, basic earnings per share attributable to Zhejiang Tianlan Environmental Protection Technology Company Limited are computed by dividing net income attributable to Zhejiang Tianlan Environmental Protection Technology Company Limited by the weighted average number of ordinary shares outstanding during the period.

**(t)** **Warranties**

The suppliers of the Group offer a standard one-year warranty to end customer of the Group. The Group only provides labour service to repair or replace parts. The Group does not maintain a general warranty reserve because historically labour costs for such repair or replacement have been de minimis.

**(u)** **Shipping and handling costs**

Amounts billed to customers related to shipping and handling are classified as revenues, and the Group's shipping and handling costs are included in cost of revenues.

**(v)** **Finance costs**

Interest relating to loans repaid is expensed in the period the repayment occurs.

**(w)** **Concentrations** 

Financial instruments that potentially subject the Group to a concentration of credit risk consist principally of cash and cash equivalents and accounts receivable, net. The Group maintains substantially all of its cash and cash equivalent balances with large financial institutions which are believed to be high quality institutions.

The Group is subject to a concentration of risk because it derives a significant portion of its revenues from a few customers. The Group's top five customers accounted for approximately 41%, 42%, and 38% of consolidated revenues for the years ended December 31, 2025, 2024 and 2023, respectively. For the years ended December 31, 2025, 2024 and 2023, one customer accounted for 16%, 16% and 22% of annual revenues, respectively.

The Group grants trade credit under contractual payment terms, generally without collateral, to its customers, which include high credit quality electric utilities, general contractors, owners and managers of industrial properties.

Consequently, the Group is subject to potential credit risk related to changes in business and economic factors. At December 31, 2025 and 2024, one (2024: Nil) of the Group's customers individually exceeded 10.0% of accounts receivable. The Group believes the terms and conditions in its contracts, billing and collection policies are adequate to minimize the potential credit risk.

**2.** **Summary of significant accounting policies (Cont'd)** 

**(x)** **Statutory reserve**

The Group is required to make appropriation to reserve, comprising the PRC statutory reserve, based on after-tax net income determined with generally accepted accounting principles of the PRC ("PRC GAAP").

Appropriations to the PRC statutory reserve are required to be at least 10% of the after tax net income determined in accordance with PRC GAAP until the reserve is equal to 50% of the entities' registered capital.

**(y)** **Fair value measurements** 

ASC 820 provides guidance on how to measure fair value for financial reporting purpose. The Group uses the three-tier hierarchy of fair value measurement, which prioritizes the inputs used in measuring fair value based upon their degree of availability in external active markets. These tiers include: Level 1 (the highest priority), defined as observable inputs, such as quoted prices in active markets; Level 2, defined as inputs other than quoted prices in active markets that are either directly or indirectly observable; and Level 3 (the lowest priority), defined as unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions.

As of December 31, 2025 and 2024, the Group determined that the carrying values of cash, and cash equivalents, accounts receivable, net, prepayments and other current assets, contract assets, bank borrowings, accounts payable, other payables and accrued expenses and contract liabilities approximate their fair values because of the short-term nature of these instruments.

**(z)** **Short-term and long-term investments** 

The Group has elected to apply the measurement alternative to equity securities without readily determinable fair values. As such, the Group's non-marketable equity securities are measured at cost, less any impairment, and are adjusted for changes in fair value resulting from observable transactions for identical or similar investments of the investee.

**(aa)** **Recent accounting pronouncements**

Changes to GAAP are typically established by the Financial Accounting Standards Board ("FASB") in the form of accounting standards updates ("ASUs") to the FASB's ASC. The Group considers the applicability and impact of all ASUs. The Group, based on its assessment, determined that any recently issued or proposed ASUs not listed below are either not applicable to the Group or may have minimal impact on its consolidated financial statements.

**2.** **Summary of significant accounting policies (Cont'd)** 

**(aa)** **Recent accounting pronouncements (Cont'd)** 

<u>Recently adopted accounting pronouncements</u>

In June 2016, the FASB issued ASU 2016-13, "Financial Instruments—Credit Losses (Topic 326), Measurement of Credit Losses on Financial Instruments". The new standard requires the measurement and recognition of expected credit losses using the current expected credit loss model for financial assets held at amortized cost, which includes the Group's accounts receivable, contract assets and non-current assets. It replaces the existing incurred loss impairment model with an expected loss methodology. The recorded credit losses are adjusted each period for changes in expected lifetime credit losses. The standard requires a cumulative effect adjustment to the consolidated balance sheet as of the beginning of the first reporting period in which the guidance is effective. ASC 326, Financial Instruments — Credit Losses is effective for public companies for annual reporting periods, and interim periods within those years beginning after December 15, 2019. For all other entities, it is effective for fiscal years beginning after December 15, 2023, including interim periods within those fiscal years. The standard is effective for the Group from January 1, 2024. The Group is in the process determining the impact of the adoption of this standard on its consolidated financial statements.

In December 2019, the FASB issued ASU 2019-12, "Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes", which simplifies the accounting for income taxes. This guidance became effective for the first quarter of 2021 on a prospective basis. The implementation of ASU 2019-12 in the year ended December 31, 2021, did not have a material impact on the Group's consolidated financial statements.

In October 2021, the FASB issued ASU 2021-08, "Business Combinations (Topic 805)". ASU 2021-08 creates an exception to the general recognition and measurement principle for contract assets and contract liabilities from contracts with customers acquired in a business combination. Under this exception, an acquirer applies ASC 606 to recognize and measure contract assets and contract liabilities on the acquisition date. ASC 805 generally requires the acquirer in a business combination to recognize and measure the assets it acquires and the liabilities it assumes at fair value on the acquisition date. The ASU 2021-08 will become effective for fiscal years beginning after December 15, 2023. The adoption of this ASU is not expected to have a material impact on the Group's consolidated financial statements.

<u>Recently issued accounting pronouncements not yet adopted</u>

In December 2023, the FASB issued ASU 2023-06, "Reference Rate Reform (Topic 848): Deferral of the Sunset Date of Topic 848". This ASU defers the sunset date of Topic 848, which provides relief to entities affected by reference rate reform. The ASU defers the sunset date of Topic 848 from December 31, 2023, to December 31, 2025. The standard is effective immediately and the Group adopted the standard in December 2023 with no financial impact. The Group is currently assessing the impact ASU 2020-04, for which this ASU 2023-06 relates, will have on its consolidated financial statements.

The Group has reviewed all recently issued, but not yet effective, accounting pronouncements and does not believe the future adoption of any such pronouncements may be expected to cause a material impact on its financial condition or the results of its operations.

**6.** **Contract assets, net and liabilities**

Contracts with customers usually stipulate the timing of payment, which is defined by the terms found within the various contracts under which work was performed during the period. Therefore, contract assets and liabilities are created when the timing of costs incurred on work performed does not coincide with the billing terms.

The Group's consolidated balance sheets present contract assets, net which contains earned unbilled revenue associated with contract work that has been completed but not paid by customers, that are generally due once the job is completed and approved.

| **21**  | **Commitments and contingencies**  |

---

(i) Insurance

The Group carries insurance policies to cover various risks, primarily general liability, automobile liability, workers' compensation and employee medical expenses under which we are liable to reimburse the insurance company for a portion of each claim paid.

(ii) Purchase commitments

To manage the risk of changes in material prices and subcontracting costs used in tendering bids for contracts, most of the time, the Group obtains firm quotations from suppliers and subcontractors before submitting a bid. These quotations do not include any quantity guarantees. As soon as the Group is advised that its bid is successful, the Group enters into firm contracts with most of its materials suppliers and sub-contractors, thereby mitigating the risk of future price variations affecting the contract costs.

(iii) Litigation

The Group is now and may in the future be involved as a party to various legal proceedings that are incidental to the ordinary course of business. Management, after consultation with legal counsel, does not believe that the outcome of these actions will have a material impact on the consolidated financial statements of the Group. There are no significant unresolved legal issues as of December 31, 2025 and 2024.

(v) Contingencies

The Group accounts for loss contingencies in accordance with ASC 450 and other related guidelines. As of December 31, 2025 and 2024, the Group's management is of the opinion that there are no commitments and contingencies to account for.

## Exhibit 16.1

**EXHIBIT 16.1**

**<u>Insider Trading POLICY</u>**

**(Effective Date: April [\*], 2026)**

**INTRODUCTION & REASONS FOR AN INSIDER TRADING POLICY**

The Board of Directors (the "***Board***") of Euro Tech Holdings Company Limited (the "***Company***") has adopted this insider trading policy (this "***Policy***") to promote compliance by Insiders (as defined below) with laws that prohibit certain persons aware of material nonpublic information about a company from (i) trading in securities of that company, or (ii) providing material nonpublic information to other persons who may trade on the basis of such information. The Policy is designed both to satisfy the Company's obligation to prevent insider trading and to help Company personnel avoid the severe consequences associated with violations of the insider trading laws. For purposes of this policy, the term "Company" includes Euro Tech Holdings Company Limited and its subsidiaries.

Federal and state securities laws generally prohibit the purchase or sale of a company's securities by persons aware of material nonpublic information about that company. These laws also prohibit persons aware of such material nonpublic information from disclosing such information to others who may trade on the basis of such information. Companies and their controlling persons are also subject to liability if they fail to take reasonable steps to prevent insider trading by their personnel.

It is important that you understand the breadth of activities that constitute illegal insider trading and their potentially severe consequences. The U.S. Securities and Exchange Commission (the "***SEC***") and the Financial Industry Regulatory Authority investigate and are very effective at detecting insider trading. The SEC pursues insider trading violations vigorously. Cases have been successfully prosecuted against trading by insiders through foreign accounts, trading by family members and friends, and trading involving only a small number of securities.

Ultimately, you are responsible for determining whether you are in possession of material nonpublic information and ensuring that you, and your family members, household members and controlled entities whose transactions are subject to this Policy, as discussed below, comply with this Policy and do not engage in illegal insider trading. Any action on the part of the Company, the Compliance Officer (as defined below) or any other officer, employee or director under this Policy (or otherwise) does not in any way constitute legal advice or insulate an individual from liability under securities laws.

**ADMINISTRATION OF THIS POLICY**

The Company's Chief Executive Officer will serve as the "***Compliance Officer***" for this Policy and shall be responsible for the administration of this Policy. If the Chief Executive Officer is absent or is otherwise unavailable, or a matter under this Policy involves the Chief Executive Officer, then the Company's Chief Financial Officer or another employee of the Company designated by the Board shall serve as the Compliance Officer for this Policy.

**APPLICABILITY OF POLICY**

***Who is covered by this Policy?***

This Policy applies to (i) Board members, officers, and other employees of the Company and its subsidiaries, and (ii) any other persons, such as consultants, contractors and temporary staff, who have access to material nonpublic information and are designated by the Company as subject to this Policy (the persons described in clauses (i) and (ii) are collectively called "***Insiders***"). Consultants, contractors and temporary staff are not employees of the Company, and nothing in this Policy should be construed to the contrary.

This Policy also applies to Family Members and Controlled Entities (as such terms are defined below) of Insiders. Insiders are responsible for ensuring that any transaction subject to this Policy engaged in by a Family Member or Controlled Entity complies with this Policy.

For purposes of this Policy, with respect to any particular Insider, (i) a "***Family Member***" means (a) any family member (*e.g.*, spouse, parent, sibling or child) of such Insider who lives in the same household as such Insider and (b) any family member of such Insider who does not live in the same household as such Insider but whose transactions in Company Securities (as such term is defined below) are directed by such Insider or are subject to such Insider's influence or control (*e.g.*, a family member who consults with the Insider before they trade in Company Securities); and (ii) a "***Controlled Entity***" means any entity that such Insider controls or whose transactions in securities are subject to such Insider's influence or control.

***What transactions are covered by this Policy?***

*Transactions in Company Securities.*

Except for Exempt Transactions (as defined below), this Policy applies to all transactions in Company Securities, as well as to derivative securities relating to the Company Securities, whether or not issued by the Company (*e.g.*, exchange-traded put and call options).

For purposes of this Policy, "***Company Securities***" means any securities issued by the Company, including, but not limited to, shares of common stock, shares of preferred stock, securities convertible into or exercisable or exchangeable for securities issued by the Company (*e.g.*, put and call options, convertible debentures, warrants), stock options and other equity-based awards, and debt securities (*e.g.*, debentures, bonds and notes).

*Transactions in Other Companies' Securities.*

This Policy also generally applies to transactions in securities of any other publicly traded company when the Insider becomes aware of material nonpublic information about such other company in the course of employment with, or the performance of services on behalf of, the Company. All Insiders should treat material nonpublic information about other publicly traded companies with the same care required regarding information about the Company. Keep in mind that information that is not material to the Company may nevertheless be material to another publicly-traded company.

*Transactions After Termination of Insider Status.*

If you are aware of material nonpublic information at the time your status as an Insider terminates, notwithstanding the termination of Insider status, this Policy will continue to apply to your transactions in Company Securities until such information becomes public or no longer material.

***What transactions are <u>not</u> covered by this Policy?***

Notwithstanding anything to the contrary in this Policy, this Policy's trading restrictions do not apply to (collectively, "***Exempt Transactions***"):

· the purchase of Company Securities from the Company;

· the sale of Company Securities to the Company;

· the purchase and sale of mutual funds, similar professionally managed "commingled pools" or exchange-traded funds that invest in Company Securities in addition to securities of other companies;

· bona fide gifts of Company's Securities to other Insiders or Family Members or Controlled Entities of an Insider;

· the exercise of a stock option awarded by the Company under one of its equity incentive plans; provided that no shares of the Company are sold in the market to fund the exercise price of such stock option or to satisfy any tax withholding obligation (the "cashless exercise" of a Company stock option through a broker involves the sale of shares of the Company in the market, and therefore would not qualify under this exception); provided, further, that, for the avoidance of doubt, this Policy does apply to transactions in the shares issued upon exercise of a stock option;

· the surrender of shares of the Company to satisfy any tax withholding obligation in a manner permitted by the applicable equity award agreement; provided that no shares of the Company are sold in the market in connection therewith;

· transactions executed under a Rule 10b5-1 trading program that (i) is entered into at a time when not in possession of material nonpublic information concerning the Company, (ii) complies with Rule 10b5-1 ("  ***Rule 10b5-1***") promulgated under the Securities Exchange Act of 1934, as amended (the "  ***Exchange Act*** "), or any successor rule, (iii) meets the Company's Rule 10b5-1 trading program requirements (attached as Exhibit A), and (iv) has been approved in advance, in writing, by the Compliance Officer; or

· purchases of Company Securities in the Company's 401(k) plan, if any, resulting from an Insider's periodic contribution of money to the plan pursuant to the Insider's payroll deduction election; provided, however, that this Policy's trading restrictions do apply to elections an Insider may make under the 401(k) plan to: (i) increase or decrease the percentage of the Insider's periodic contributions that will be allocated to the Company stock fund; (ii) make an intra-plan transfer of an existing account balance into or out of the Company stock fund; (iii) borrow money against the Insider's 401(k) plan account if the loan will result in a liquidation of some or all of the Insider's Company stock fund balance; and (iv) pre-pay a 401(k) plan loan if the pre-payment will result in allocation of loan proceeds to the Company stock fund.

**STATEMENT OF POLICY**

***What is the Company's general policy on insider trading and disclosure of nonpublic information?***

The Company opposes the unauthorized disclosure of any nonpublic information by an Insider acquired in the course of employment with, or the performance of services on behalf of, the Company and the misuse of material nonpublic information acquired in the course of employment with, or the performance of services on behalf of, the Company in securities trading.

***What policies and procedures am I required to adhere to before trading in securities?***

*Trading on Material Nonpublic Information is Prohibited.*

Insiders may not engage in any transaction involving a purchase or sale of Company Securities, including any offer to purchase or offer to sell, directly or through family members or other persons or entities, if they are aware of material nonpublic information relating to the Company. Similarly, Insiders may not trade in the securities of any other publicly traded company if they become aware of material nonpublic information about that other company in the course of employment with, or the performance of services on behalf of, the Company.

Because the Company's stockholders and the investing public should be afforded time to receive and absorb material nonpublic information, for purposes of this Policy, as a general rule, you may not engage in any transactions prohibited by this Policy until after two (2) full Trading Sessions (as defined below) following the widespread public release of the applicable information. Thus, for example, if material nonpublic information is publicly disseminated *before* 9:30 a.m. Eastern Time on a Monday, you may not engage in any transactions prohibited by this Policy until after the Trading Session ends on Tuesday, assuming Trading Sessions took place on Monday and Tuesday. Likewise, if material nonpublic information is publicly disseminated *before* 9:30 a.m. Eastern Time on a Friday, you may not engage in any transactions prohibited by this Policy until after the Trading Session ends on Monday, assuming Trading Sessions took place on Friday and Monday. As another example, if material nonpublic information is publicly disseminated *after* 9:30 a.m. on a Monday, you may not engage in any transactions prohibited by this Policy until after the Trading Session ends on Wednesday, assuming Trading Sessions took place on Tuesday and Wednesday. However, if the applicable information is complex, such as a significant corporate transaction, it may be necessary to allow additional time for the information to be absorbed by the Company's stockholders and investing public. In such circumstances, you will be notified by the Compliance Officer regarding a suitable additional waiting period before you may engage in any transactions prohibited by this Policy.

For purposes of this Policy, a "***Trading Session***" means a regular trading session of the United States national securities exchange on which the Company's common stock is primarily listed, typically 9:30 a.m. Eastern Time to 4:00 p.m. Eastern Time on business days. For the avoidance of doubt, a Trading Session includes a pre-scheduled abbreviated trading session, such as sessions ending at 1:00 p.m. Eastern Time on the day before Thanksgiving and on Christmas Eve, where applicable.

*Black-Out Periods; Preclearance.*

While it is never permissible to trade based on material nonpublic information, the following procedures have been adopted to help prevent inadvertent violations of this Policy and to avoid even the appearance of an improper transaction*.*

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) <u>Regularly Scheduled Black-Out Periods</u>. Board members, Senior Management, Financial Team Members, Designated Employees (each as defined below) and Family Members and Controlled Entities of such individuals are prohibited from trading in the Company's Securities during the following periods (a "***regularly scheduled black-out period***"):

· the period beginning at 12:01 a.m. Eastern Time on the date that is two (2) calendar days prior to the end of each fiscal quarter until after two (2) full Trading Sessions following the widespread public release of the Company's financial results for the applicable quarter and, in the case of the fourth quarter, financial results for the year ended; and

· any other periods as determined by the Compliance Officer.

The individuals designated as "***Senior Management,***" "***Financial Team Members***" and "***Designated Employees***" are listed on Schedules A-1, A-2 and A-3, respectively. The Compliance Officer may, from time to time, update the list of individuals designated as, and/or designate additional individuals as, Senior Management, Financial Team Members or Designated Employees, in which case the Compliance Officer shall notify the affected individuals.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) <u>Special Black-Out Periods</u>. Insiders and their Family Members and Controlled Entities are prohibited from trading in the Company's Securities during the following periods (a "***special blackout period***"):

· from the time each such individual becomes aware of the material nonpublic information (the black-out start times often vary), until after two (2) full Trading Sessions following the widespread public announcement of the applicable information, unless the information released is complex, in which case it may be necessary to extend this period and the Compliance Officer will notify you of any such extension; and

· during other specified periods when significant developments or announcements are anticipated, as notified by the Compliance Officer.

You will be notified by e-mail when you may not trade in the Company's Securities during a special blackout period, in which event you will also be notified when trading restrictions are lifted. The existence of a special blackout period may not be announced to all Company personnel and you should not communicate the existence of a special blackout period to any other person. Even if the Company has not designated you as a person to whom a special blackout period applies, you should not trade if you are aware of material nonpublic information because you are responsible at all times for not engaging in illegal insider trading.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(3) <u>Preclearance Procedures</u>. In order to ensure compliance with this Policy and with any Section 16 reporting requirements, Board members, Senior Management, Financial Team Members, Designated Employees and their respective Family Members and Controlled Entities must obtain written preclearance from the Compliance Officer of any proposed transaction to which this Policy's restrictions apply prior to commencing any transaction in Company Securities, or in derivative securities not issued by the Company but that relate to Company Securities. The Compliance Officer is under no obligation to approve a transaction submitted for preclearance and may determine not to permit the transaction. When making a request for preclearance, the requestor should carefully consider whether he or she may be aware of any material nonpublic information relating to the Company and must fully describe the applicable facts and circumstances to the Compliance Officer. The procedure for making a request for preclearance may be obtained from the Compliance Officer.

*No Exception for Hardship.*

An Insider may, from time to time, have to forego a proposed transaction in Company Securities even if he or she planned to make the transaction before learning of the material nonpublic information and even though the Insider believes he or she may suffer an economic loss or forego anticipated profit by waiting. The existence of a personal financial emergency does not excuse you from compliance with applicable securities laws or this Policy.

***May I disclose nonpublic information about the Company or about other companies to others?***

*Maintaining the Confidentiality of Nonpublic Information.*

Unauthorized disclosure of any confidential information of the Company or of any other company of which you become aware of in the course of employment with, or the performance of services on behalf of, the Company is prohibited.

Maintaining the confidentiality of Company information is essential for competitive, security and other business reasons, as well as to comply with applicable securities laws. You should treat all information you learn about the Company or its business plans in connection with your employment with, or the performance of services on behalf of, the Company as confidential and proprietary to the Company. Inadvertent disclosure of confidential information may expose the Company and you to significant risk of investigation and litigation.

The timing and nature of the Company's disclosure of material information to outsiders is subject to legal rules, the breach of which could result in substantial liability to you, the Company and its management. Accordingly, it is important that responses to inquiries about the Company by the press, analysts or others in the financial community be made on the Company's behalf only through authorized individuals.

This Policy should not be interpreted to modify any agreement between the Company and an Insider relating to use or protection of confidential information, or the Insider's obligations relating to confidential information under the Company's Code of Business Conduct and Ethics or under any other Company policy.

If you receive inquiries about the Company from analysts, reporters, or others, decline to comment and direct them to the Chief Executive Officer or such other persons as the Chief Executive Officer may designate.

As a precaution, keep all memoranda, correspondence and other documents that reflect nonpublic information in a secure place (*e.g.*, a locked office or a locked file cabinet) so they cannot be accessed by third parties.

*Prohibition on "Tipping."*

Insiders may be liable under securities laws for communicating (or "***tipping***") material nonpublic information about the Company or about any other public company of which you become aware of in the course of employment with, or the performance of services on behalf of, the Company to another person who trades, directly or indirectly, on the information tipped to them. "Tipping" is illegal and prohibited under this Policy. No Insider shall disclose material nonpublic information relating to the Company or about any other public company of which you become aware of in the course of employment with, or the performance of services on behalf of, the Company to any other person (including, but not limited to, family members, friends, business associates and investors), unless any such disclosure is made in accordance with the Company's policies regarding the protection or authorized disclosure of nonpublic information. Further, Insiders may not make recommendations or express opinions on the basis of material nonpublic information as to trading in Company Securities. Even if you are not in possession of material nonpublic information, do not recommend to any other person that they buy or sell securities of the Company. Remember that "tipping" material nonpublic information is always prohibited, and that your recommendation could be imputed to the Company and may be misleading if you do not have all relevant information.

Do not discuss material nonpublic information where it may be overheard, such as in restaurants, elevators, restrooms, and other public places. Remember that phone conversations are often overheard and that persons other than intended recipients may retrieve voicemails, e-mails, text messages and other electronic communications.

***May I trade in Company derivative securities or short sell Company Securities?***

The Company considers it improper and inappropriate for Insiders to engage in short-term or speculative transactions in Company Securities or in other transactions in Company Securities that may lead to inadvertent violations of the insider trading laws. Accordingly, trading in Company Securities is subject to the following restrictions:

*Short Sales*. You may not engage in "short sales" of Company Securities (*i.e.*, sales of securities that are not then owned).

*Publicly Traded Options*. You may not engage in transactions in publicly traded options (*e.g.*, puts, calls and other derivative securities), on an exchange or in any other organized market on Company Securities.

*Standing Orders*. Standing orders should be used only for a very brief period of time and should not be used during any regularly scheduled black-out period or any special blackout period. A standing order placed with a broker to sell or purchase securities at a specified price leaves you with no control over the timing of the transaction. A standing order transaction executed by the broker when you are aware of material nonpublic information may result in unlawful insider trading and violation of this Policy. Should you have an open standing order, you must cancel the order before the beginning of a regularly scheduled black-out period or as soon as you become aware of material nonpublic information, including as soon as you become aware of the existence of a special blackout period.

*Hedging Transactions*. You may not engage in any kind of hedging transaction that could reduce or limit your holdings, ownership or interest in or to any Company Securities, including, without limitation, outstanding stock options, deferred share units, restricted share units, or other compensation awards the value of which are derived from, referenced to or based on the value or market price of securities of the Company. Prohibited transactions include the purchase of financial instruments, including prepaid variable forward contracts, instruments for the short sale or purchase or sale of call or put options, equity swaps, collars, or units of exchangeable funds, that are designed to or that may reasonably be expected to have the effect of hedging or offsetting a decrease in the market value of any securities of the Company.

*Margin Accounts and Pledges*. Securities held in a margin account or pledged as collateral for a loan may be sold without your consent by the broker if you fail to meet a margin call or by the lender in foreclosure if you default on the loan. Because a margin or foreclosure sale may occur at a time when you are aware of material nonpublic information or otherwise are not permitted to trade in Company Securities, you are prohibited from holding Company Securities in a margin account or pledging Company Securities as collateral for a loan.

***May I pre-establish a time for the purchase or sale of Company Securities at a time that I am not aware of material nonpublic information?***

Yes, directors, officers and other employees of the Company may establish written trading programs pursuant to Rule 10b5-1. Any such trading program is subject to the restrictions and limitation in <u>Exhibit A</u>, which may be updated from time to time to conform with changes to Rule 10b5-1 or the practices thereunder. Once a Rule 10b5-1 trading program is implemented in accordance with <u>Exhibit A</u>, trades pursuant to, and in accordance with, such program are not subject to the limitations and restrictions set forth in this Policy. Every Rule 10b5-1 trading program (or the form of program established by an investment bank or other third party) must be reviewed and approved by the Compliance Officer prior to establishment to confirm compliance with this Policy and applicable securities laws.

**POTENTIAL CRIMINAL AND CIVIL LIABILITY AND/OR DISCIPLINARY ACTION**

***What legal liability may I be subject to if I engage in securities transactions on the basis of material nonpublic information?***

Insiders that engage in securities transactions at a time when they are aware of material nonpublic information may be subject to penalties that include:

· imprisonment for up to 20 years;

· criminal fines of up to $5 million; and

· civil fines of up to three times the profit gained or the loss avoided.

***What legal liability may I be subject to if I disclose material nonpublic information to others who engage in securities transactions?***

Insiders may be liable for improper transactions by any person (commonly called a "***tippee***") to whom they have disclosed material nonpublic information regarding the Company or to whom they have made recommendations or expressed opinions on the basis of such information as to trading in Company Securities. The SEC has imposed large penalties even when the disclosing person did not profit from the trading. The SEC, the stock exchanges and the Financial Industry Regulatory Authority use sophisticated electronic surveillance techniques to uncover insider trading.

***Could the Company incur liability for my actions if I engage in securities transactions at a time that I have material nonpublic information?***

If the Company fails to take appropriate steps to prevent illegal insider trading, the Company may have "controlling person" liability for a trading violation, with civil penalties, as well as a criminal penalty of up to $25 million. The civil penalties can extend personal liability to the Company's directors, officers and other supervisory personnel if they fail to take appropriate steps to prevent insider trading.

***What disciplinary actions may the Company take for violations of this Policy?***

The Company expects strict compliance with this Policy and the procedures under this Policy by all Insiders. Failure to so comply may result in serious legal consequences for you, as well as the Company. A failure to follow the letter and spirit of this Policy and its procedures would be considered a matter of extreme seriousness. All Insiders must execute a certificate in the form attached as <u>Exhibit B</u>, pursuant to which they certify that, among other things, such persons are currently, and will continue to be, in compliance with this Policy.

Insiders who violate this Policy may be subject to disciplinary action by the Company. Such disciplinary action may include ineligibility for future participation in the Company's equity incentive plans, other Company imposed sanctions, suspension or termination of employment.

**DEFINITION OF MATERIAL NONPUBLIC INFORMATION**

Material nonpublic information has two important elements: materiality and public availability.

***What information is material?***

It is not possible to define all categories of material information. However, information should be regarded as material if there is a reasonable likelihood that it would be considered important to an investor in making an investment decision (*i.e.*, a decision to buy, hold or sell a security), or if it would significantly alter the total mix of information available to investors. While it may be difficult under this standard to determine whether particular information is material, there are various categories of information that are particularly sensitive and, as a general rule, should always be considered material. Examples of such information include:

· financial results;

· projections of future earnings or losses;

· news of a pending or proposed merger or acquisition;

· news of the disposition of a subsidiary or significant assets;

· impending bankruptcy or financial liquidity problems;

· gain or loss of a substantial customer or supplier;

· changes in a dividend policy;

· new project developments or announcements of a significant nature

· developments, decisions or communications related to the Company by regulatory authorities;

· stock splits;

· new equity or debt offerings;

· significant litigation exposure due to actual or threatened litigation or developments in existing litigation;

· significant changes in senior management;

· information as to the success, failure or even the unchanging status of particular aspects of the Company's business; and

· significant cybersecurity incidents, such as a data breach or any other significant disruption in the Company's operations or the loss, potential loss, breach or unauthorized access of its property or assets.

Both positive and negative information may be material. Because trading that receives scrutiny will be evaluated after the fact with the benefit of hindsight, questions concerning the materiality of particular information should be resolved in favor of materiality, and trading should be avoided.

***What constitutes nonpublic information?***

Nonpublic information is information that has not been previously disclosed to the general public and is otherwise not available to the general public. One common misconception is that material information loses its "nonpublic" status as soon as a press release is issued disclosing the information. In fact, information is considered available to the public only when it has been released broadly to the marketplace (*e.g.*, by a press release or an SEC filing) and the investing public has had time to absorb the information fully. For more information, see "STATEMENT OF POLICY—What policies and procedures am I required to adhere to before trading in securities?", above.

**ADDITIONAL INFORMATION: DIRECTORS AND OFFICERS**

Board members and certain officers of the Company are subject to the reporting obligations of Section 16(a) of the Exchange Act, which requires them to publicly report their beneficial ownership of, and changes in their beneficial ownership of, Company Securities by filing reports with the SEC. The Compliance Officer is responsible for assisting directors and officers in maintaining their EDGAR filing access and coordinating the timely preparation and submission of required reports. Directors and officers subject to the preclearance requirements of this Policy should notify the Compliance Officer of any proposed transaction in Company Securities sufficiently in advance to allow coordination of both preclearance approval and any associated Section 16(a) filing obligation.

Please note that the short-swing profit recovery provisions of Section 16(b) of the Exchange Act - which would require disgorgement of profits from purchases and sales of Company Securities within any six-month period - do not currently apply to the Company's directors and officers.

**POLICY INTERPRETATION AND AMENDMENTS**

The Compliance Officer is authorized to interpret this Policy as necessary. The Compliance Officer may authorize deviations in the procedures in this Policy, provided those deviations are consistent with the general purpose of this Policy and applicable securities laws. Any such deviations must be confirmed in writing.

Any amendment to this Policy must be approved by the Board.

**QUESTIONS ABOUT THIS POLICY**

Please direct your questions as to any matters discussed in this Policy to the Compliance Officer.

**As of [\*], 2026**

**Schedule A-1<u> </u>**

Senior Management

All Executive Officers (subject to Section 16(a) reporting obligations), including:

1. Chief Executive Officer

2. Chief Financial Officer

**Schedule A-2 <u>Financial Team Members</u>**

All members of the Company's financial team, including:

1. All members of Senior Management

2. All persons who directly report to the Company's Chief Executive Officer

3. All persons in a manager position or above in the Company's finance department

**Schedule A-3 <u>Designated Employees</u>**

None.

**<u>EXHIBIT A</u>**

Rule 10b5-1 trading programs established pursuant to this Policy (each a "***Program***") are limited to:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) A written trading plan (commonly called a non-discretionary Rule 10b5-1 plan) that permits automatic trading of Company Securities through a third party broker (an "***Automatic Trading Program***") established by a director, officer or other employee of the Company (a "***Program Eligible Person***" or "***you***" in this <u>Exhibit A</u>) at a time when the Program Eligible Person is not aware of material nonpublic information (and, in the case of Board members, Senior Management and Financial Team Members, not during a regularly scheduled black-out period or special blackout period). The Automatic Trading Program must specify the number (or dollar value) of Company Securities to be purchased or sold, the price (which may be a fixed price, market price or minimum/maximum price) at which the Company Securities are to be traded, and the date(s) on which the trades are to be made. Alternatively, the Automatic Trading Program may include a written formula or algorithm, or computer program, for determining the amount of securities to be purchased or sold and the price at which and the date on which the securities were to be purchased or sold (*e.g.*, the number of shares could be specified as a percentage of the holdings of the Program Eligible Person); or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) A Program where transactions in Company Securities are initiated by the trustee of a so-called "blind" trust, provided the Program is established by a Program Eligible Person at a time when the Program Eligible Person is not aware of material nonpublic information. A "blind" trust is a trust established by a Program Eligible Person. An independent trustee without any involvement or even knowledge of the Program Eligible Person must make the investment and disposition decisions. The trustee should be a recognized financial institution possessing trust powers. Under this type of Program, the Program Eligible Person cannot exert any influence over, or even communicate with, the trustee regarding specific investments. If the trustee becomes aware of material nonpublic information regarding the Company, whether from the Program Eligible Person or otherwise, the trustee may not engage in a purchase or sale of Company Securities.

*Additional Program Restrictions*. All Programs are subject to the requirements of Rule 10b5-1 and to the following:

· The Program must provide that no trades may occur thereunder until expiration of the applicable cooling-off period specified in Rule 10b5-1(c)(ii)(B), and no trades occur under the Program until after that time.

o The applicable cooling-off period varies based on the status of the Program Eligible Person.

o For directors and officers, the cooling-off period ends on the later of (x) ninety (90) days after adoption or modification of the Program; and (y) two (2) business days following disclosure of the Company's financial results in a Form 20-F or Form 6-K (in the case of interim financial results) for the fiscal period in which the Program was adopted.

o For all other Program Eligible Persons, the cooling-off period ends thirty (30) days after the adoption or modification of the Program.

· The Program must include an expiration date that is at least six (6) months but not more than eighteen (18) months from the effective date of the Program. Shorter-term Programs may be viewed as an attempt to make advantageous short-term trades, and longer-term Programs are likely to have to be amended or terminated, which defeats the ultimate purpose of Programs.

· Once the Program is established, the Program must not permit the Program Eligible Person to exercise any influence or control over the amount of Company Securities to be traded, the price(s) at which they are to be traded or the date(s) on which the trades are to be made.

· The Program Eligible Person cannot engage in any separate transaction (e.g., a hedging transaction) that directly or indirectly alters or offsets a trade under the Program.

· The Program must allow for the cancellation of a transaction and/or suspension of a Program upon notice and request by the Company to the extent the Program or any proposed trade thereunder (i) fails to comply with applicable law (e.g., exceeding the number of shares which the Program Eligible Person may sell under Rule 144 in a rolling three month period), or (ii) would create material adverse consequences for the Company (e.g., due to the imposition of lock-up agreements on the Program Eligible Person).

· Any Program entered into by a Program Eligible Person must be the only outstanding Program for such Program Eligible Person, subject to the exceptions set out in Rule 10b5-1(c)(ii)(D).

· Subject to and in accordance with the terms of Rule 10b5-1, a Program Eligible Person may not have more than one "single trade" Program during any twelve (12)-month period.

· The Program must be entered into (a) in good faith and not as part of a plan or scheme to evade the prohibitions of the securities laws (including, without limitation, Rule 10b5-1) and (b) at a time when the Program Eligible Person is not aware of material nonpublic information about the Company; and if the Program Eligible Person is a director or officer of the Company, the Program for such director or officer must include representations by the director or officer certifying as to the matters described in clauses (a) and (b).

*Amendment, Suspension or Termination of Programs*. Any modification or change to the amount, price, or timing of the purchase or sale of the securities underlying a Program is considered a termination of such Program and the adoption of a new Program. Amendments, suspensions, and terminations of Programs will be viewed in hindsight and could call into question whether the Program was entered into in good faith. As a result, amendments, suspensions, and terminations of Programs (unless in accordance with the terms of the Program when established) require preapproval of the Compliance Officer, who will inquire into the change in circumstances that has occurred since the inception of the Program giving rise to the requested amendment, suspension, or termination. Scheduled sales or purchases of securities pursuant to a Program will not be halted during the pendency of the amendment, suspension, or termination request. The Company has the right at any time to require additional and/or different requirements in connection with the amendment, suspension, or termination of a Program in order to protect you and the Company from potential liability. Further, a Program may be terminated or suspended by the Company at any time and for any reason.

In addition, you may voluntarily amend, suspend or terminate a Program, subject to these conditions:

· A Program Eligible Person must obtain preclearance from the Compliance Officer to amend, suspend or terminate their Program.

· A Program Eligible Person may not amend, suspend or terminate their Program during a regularly scheduled black-out period or special blackout period or if at the time of the amendment, suspension or termination, the Program Eligible Person possesses material nonpublic information concerning the Company. A Program Eligible Person must sign a certificate in favor of the Company affirmatively stating that they do not possess material nonpublic information concerning the Company at the time of the amendment, suspension or termination.

· The amendment, suspension or termination must include any applicable cooling-off period pursuant to Rule 10b5-1.

· No suspension of a Program may exceed sixty (60) calendar days.

· At least one (1) year must elapse between the termination of a Program and the entry into a new Program.

· A Program Eligible Person will be limited to one amendment or suspension of their Program during its term.

*Company Disclosure*. The Company will be required to make certain disclosures in accordance with Rule 10b5-1 regarding any adoption, modification or termination of a Program by any person subject to Section 16 of the Exchange Act. Upon the occurrence of any such adoption, modification or termination, such persons must promptly furnish the Compliance Officer with information regarding the date of adoption, termination or modification of the Program, the Program's duration, the aggregate number of securities to be sold or purchased under the Program and any other information reasonably requested by the Compliance Officer.

**You have the ultimate and exclusive responsibility for adhering to the requirements set forth herein. Any action on the part of the Company, the Compliance Officer, or any other person pursuant to this Policy (or otherwise) does not in any way constitute legal advice or insulate you from liability under securities laws. You must notify the Compliance Officer if you become aware of a breach of the requirements, either by you or by another person subject to this Policy. The Company shall have no liability to any Program Eligible Person as a result of the establishment of a Program, any disclosure by the Company with respect thereto, or any cancellation or transactions and/or suspension of a Program as discussed above.**

## Exhibit 97.1

**EXHIBIT 97.1**

**EURO TECH HOLDINGS COMPANY LIMITED**

**INCENTIVE COMPENSATION CLAWBACK POLICY**

The Board of Directors (the "<u>Board</u>") of Euro Tech Holdings Company Limited (the "<u>Company</u>") has adopted this Incentive Compensation Clawback Policy (the "<u>Policy</u>"), which requires the recoupment of certain incentive-based compensation in accordance with the terms herein and is intended to comply with Rule 10D-1 under the Exchange Act, and Nasdaq Listing Rule 5608, as each may be amended from time to time (together, the "<u>applicable listing standards</u>"). This Policy shall be deemed effective as of the Effective Date.

**1.** **Definitions** 

For purposes of this Policy, the following definitions shall apply:

a) " <u>Committee</u> " means the committee of the Board responsible for executive compensation decisions, which shall be composed entirely of independent directors, or, if no such committee exists, a majority of the independent directors then serving on the Board, or, if no such majority exists, the Board as a whole.

b) " <u>Company Group</u> " means the Company and each of its subsidiaries or consolidated affiliated entities, as applicable.

c) " <u>Compliance Officer</u> " has the meaning given to that term in the Company's Insider Trading Policy, as amended from time to time.

d) " <u>Covered Compensation</u> " means any Incentive-Based Compensation granted, vested or paid to a person who served as an Executive Officer at any time during the performance period for the Incentive-Based Compensation and that was Received (i) on or after the Effective Date, (ii) after the person became an Executive Officer, and (iii) at a time that the Company had a class of securities listed on a national securities exchange or a national securities association such as Nasdaq.

e) " <u>Effective Date</u> " means October 2, 2023, being the date on which the applicable listing standards became effective.

f) " <u>Erroneously Awarded Compensation</u> " means the amount of Covered Compensation granted, vested or paid to a person during the fiscal period when the applicable Financial Reporting Measure relating to such Covered Compensation was attained that exceeds the amount of Covered Compensation that otherwise would have been granted, vested or paid to the person had such amount been determined based on the applicable Restatement, computed without regard to any taxes paid (*i.e.*, on a pre-tax basis). For Covered Compensation based on stock price or total shareholder return, where the amount of Erroneously Awarded Compensation is not subject to mathematical recalculation directly from the information in a Restatement, the Committee will determine the amount of such Covered Compensation that constitutes Erroneously Awarded Compensation, if any, based on a reasonable estimate of the effect of the Restatement on the stock price or total shareholder return upon which the Covered Compensation was granted, vested or paid and the Committee shall maintain documentation of such determination and provide such documentation to Nasdaq.

g) " <u>Exchange Act</u> " means the U.S. Securities Exchange Act of 1934, as amended.

h) " <u>Executive Officer</u> " means the Company's president, principal financial officer, principal accounting officer (or if there is no such accounting officer, the controller), any vice-president of the Company in charge of a principal business unit, division, or function (such as sales, administration, or finance), any other officer who performs a policy-making function, or any other person (whether or not an officer of employee of the Company) who performs similar policy-making functions for the Company. Executive officers of the Company's parent(s) or subsidiaries are deemed executive officers of the Company if they perform such policy making functions for the Company. "Policy-making function" does not include policy-making functions that are not significant. Both current and former Executive Officers are subject to the Policy in accordance with its terms.

i) " <u>Financial Reporting Measure</u> " means (i) any measure that is determined and presented in accordance with U.S. GAAP, the accounting principles used in preparing the Company's financial statements, and any measures derived wholly or in part from such measures, including non-U.S. GAAP financial measures, (ii) stock price, or (iii) total shareholder return. Financial Reporting Measures need not be presented within the Company's financial statements or included in a filing with the SEC.

j) " <u>Home Country</u> " means the Company's jurisdiction of incorporation, *i.e.*, the British Virgin Islands.

k) " <u>Incentive-Based Compensation</u> " means any compensation that is granted, earned or vested based wholly or in part upon the attainment of a Financial Reporting Measure.

l) " <u>Lookback Period</u> " means the three completed fiscal years (plus any transition period of less than nine months that is within or immediately following the three completed fiscal years and that results from a change in the Company's fiscal year) immediately preceding the date on which the Company is required to prepare a Restatement for a given reporting period, with such date being the earlier of: (i) the date the Board, a committee of the Board, or the officer or officers of the Company authorized to take such action if Board action is not required, concludes, or reasonably should have concluded, that the Company is required to prepare a Restatement, or (ii) the date a court, regulator or other legally authorized body directs the Company to prepare a Restatement. A transition period between the last day of the Company's previous fiscal year end and the first day of its new fiscal year that comprises a period of nine to 12 months would be deemed a completed fiscal year. Recovery of any Erroneously Awarded Compensation under the Policy is not dependent on if or when the restated financial statements are filed.

m) " <u>Nasdaq</u> " means the Nasdaq Stock Market.

n) " <u>Received</u> ": Incentive-Based Compensation is deemed "Received" in the Company's fiscal period during which the Financial Reporting Measure specified in or otherwise relating to the Incentive-Based Compensation award is attained, even if the grant, vesting or payment of the Incentive-Based Compensation occurs after the end of that period.

o) " <u>Restatement</u> " means a required accounting restatement of any Company financial statement due to the material noncompliance of the Company with any financial reporting requirement under the securities laws, including (i) to correct an error in previously issued financial statements that is material to the previously issued financial statements (commonly referred to as a "Big R" restatement) or (ii) to correct an error in previously issued financial statements that is not material to the previously issued financial statements but that would result in a material misstatement if the error were corrected in the current period or left uncorrected in the current period (commonly referred to as a "little r" restatement). Changes to the Company's financial statements that do not represent error corrections under the then-current relevant accounting standards will not constitute Restatements. Recovery of any Erroneously Awarded Compensation under the Policy is not dependent on fraud or misconduct by any person in connection with the Restatement.

**2.** **Recovery of Erroneously Awarded Compensation** 

In the event of a Restatement, any Erroneously Awarded Compensation Received during the Lookback Period prior to the Restatement (a) that is then-outstanding but has not yet been paid shall be automatically and immediately forfeited and (b) that has been paid to any person shall be subject to reasonably prompt repayment to the Company Group in accordance with Section 3 of this Policy. The Committee must pursue (and shall not have the discretion to waive) the forfeiture and/or repayment of such Erroneously Awarded Compensation in accordance with Section 3 of this Policy, except as provided below.

Notwithstanding the foregoing, the Committee (or, if the Committee is not a committee of the Board responsible for the Company's executive compensation decisions and composed entirely of independent directors, a majority of the independent directors serving on the Board) may determine not to pursue the forfeiture and/or recovery of Erroneously Awarded Compensation from any person if the Committee determines that such forfeiture and/or recovery would be impracticable due to any of the following circumstances: (i) the direct expense paid to a third party (for example, reasonable legal expenses and consulting fees) to assist in enforcing the Policy would exceed the amount to be recovered, including the costs that could be incurred if pursuing such recovery would violate local laws other than the Company's Home Country laws (following reasonable attempts by the Company Group to recover such Erroneously Awarded Compensation, the documentation of such attempts, and the provision of such documentation to Nasdaq), (ii) pursuing such recovery would violate the Company's Home Country laws adopted prior to November 28, 2022 (provided that the Company obtains an opinion of Home Country counsel acceptable to Nasdaq that recovery would result in such a violation and provides such opinion to Nasdaq), or (iii) recovery would likely cause any otherwise tax-qualified retirement plan, under which benefits are broadly available to employees of the Company Group, to fail to meet the requirements of 26 U.S.C. 401(a)(13) or 26 U.S.C. 411(a) and regulations thereunder.

**3.** **Means of Repayment** 

In the event that the Committee determines that any person shall repay any Erroneously Awarded Compensation, the Committee shall provide written notice to such person by email or certified mail to the physical address on file with the Company Group for such person, and the person shall satisfy such repayment in a manner and on such terms as required by the Committee, and the Company Group shall be entitled to set off the repayment amount against any amount owed to the person by the Company Group, to require the forfeiture of any award granted by the Company Group to the person, or to take any and all necessary actions to reasonably promptly recover the repayment amount from the person, in each case, to the fullest extent permitted under applicable law, including without limitation, Section 409A of the U.S. Internal Revenue Code and the regulations and guidance thereunder. If the Committee does not specify a repayment timing in the written notice described above, the applicable person shall be required to repay the Erroneously Awarded Compensation to the Company Group by wire, cash, cashier's check or other means as agreed by the Committee no later than thirty (30) days after receipt of such notice.

To the extent that any recovery of Erroneously Awarded Compensation results in a change in the beneficial ownership of Company securities by a director or officer subject to the reporting obligations of Section 16(a) of the Exchange Act, the relevant person shall promptly notify the Compliance Officer, who shall coordinate the timely filing of any required report under Section 16(a).

**4.** **No Indemnification** 

No person shall be indemnified, insured or reimbursed by the Company Group in respect of any loss of compensation by such person in accordance with this Policy, nor shall any person receive any advancement of expenses for disputes related to any loss of compensation by such person in accordance with this Policy, and no person shall be paid or reimbursed by the Company Group for any premiums paid by such person for any third-party insurance policy covering potential recovery obligations under this Policy. For this purpose, "indemnification" includes any modification to current compensation arrangements or other means that would amount to *de facto* indemnification (for example, providing the person a new cash award which would be cancelled to effect the recovery of any Erroneously Awarded Compensation). In no event shall the Company Group be required to award any person an additional payment if any Restatement would result in a higher incentive compensation payment.

**5.** **Miscellaneous** 

This Policy generally will be administered and interpreted by the Committee, provided that the Board may, from time to time, exercise discretion to administer and interpret this Policy, in which case, all references herein to "Committee" shall be deemed to refer to the Board. Any determination by the Committee with respect to this Policy shall be final, conclusive and binding on all interested parties. Any discretionary determinations of the Committee under this Policy, if any, need not be uniform with respect to all persons, and may be made selectively amongst persons, whether or not such persons are similarly situated.

This Policy is intended to satisfy the requirements of Section 954 of the Dodd-Frank Wall Street Reform and Consumer Protection Act, as it may be amended from time to time, and any related rules or regulations promulgated by the SEC or Nasdaq, including any additional or new requirements that become effective after the Effective Date which upon effectiveness shall be deemed to automatically amend this Policy to the extent necessary to comply with such additional or new requirements.

The provisions in this Policy are intended to be applied to the fullest extent of the law. To the extent that any provision of this Policy is found to be unenforceable or invalid under any applicable law, such provision will be applied to the maximum extent permitted and shall automatically be deemed amended in a manner consistent with its objectives to the extent necessary to conform to applicable law. The invalidity or unenforceability of any provision of this Policy shall not affect the validity or enforceability of any other provision of this Policy. Recovery of Erroneously Awarded Compensation under this Policy is not dependent upon the Company Group satisfying any conditions in this Policy, including any requirements to provide applicable documentation to Nasdaq.

The rights of the Company Group under this Policy to seek forfeiture or reimbursement are in addition to, and not in lieu of, any rights of recovery, or remedies or rights other than recovery, that may be available to the Company Group pursuant to the terms of any law, government regulation or stock exchange listing requirement or any other policy, code of conduct, employee handbook, employment agreement, equity award agreement, or other plan or agreement of the Company Group.

The Company shall file this Policy as an exhibit to its Annual Report on Form 20-F in accordance with the requirements of the applicable listing standards and the rules of the SEC. The Company shall disclose in its Annual Report on Form 20-F any actions taken pursuant to this Policy during the relevant fiscal year, including any determination by the Committee that recovery of Erroneously Awarded Compensation would be impracticable, to the extent required by applicable SEC rules and listing standards.

**6.** **Amendment and Termination** 

To the extent permitted by, and in a manner consistent with applicable law, including SEC and Nasdaq rules, the Committee may terminate, suspend or amend this Policy at any time in its discretion.

**7.** **Successors** 

This Policy shall be binding and enforceable against all persons and their respective beneficiaries, heirs, executors, administrators or other legal representatives with respect to any Covered Compensation granted, vested or paid to or administered by such persons or entities.
