Competitive Intelligence

Global Market Structure & Dynamics

Industry Characteristics: The domestic market for pipe and fitting products in China is fragmented and highly competitive. The industry includes a few relatively large companies and over a hundred smaller regional companies. Competition also arises from imported products and globally recognized manufacturers. The market for some pipe and fitting products is characterized by low barriers to entry, leading to price competition and pressure on margins from less expensive domestic producers.

Competitive Positioning Matrix:

Direct Competitors

Primary Competitors: The filing does not name specific direct competitors but notes competition from "a few relatively large companies" and "more than one hundred smaller companies with regional presences" in China, as well as "products imported to China or produced by manufacturers that are already globally recognized." Regional Competitive Dynamics: The competitive landscape varies by region, with local protectionism and supply chain fragmentation within China posing challenges.

Risk Assessment Framework

Strategic & Market Risks

Global Market Dynamics:

• Economic Slowdown: Deterioration in global and Chinese economic conditions, particularly in the real estate and hospitality sectors, could reduce demand for the company's products and adversely affect sales and operating results.
• Customer Spending Decrease: Reliance on consumer spending to drive sales means a decrease in spending could negatively impact demand.
• Customer Concentration: While no single customer accounts for over 10% of revenue, reliance on specific industries (water and gas supply, construction) exposes the company to risks if these industries experience a protracted slowdown.

Operational & Execution Risks

Global Supply Chain Vulnerabilities:

• Supplier Dependency: Dependence on a few major vendors (two vendors accounted for 50% of purchases in 2025) for raw materials, though the company believes replacement vendors are readily available.
• Regional Disruptions: Supply chain fragmentation and local protectionism within China complicate raw material transportation and product delivery.
• Trade Restrictions: Potential imposition of trade barriers, customs duties, and tariffs in targeted emerging markets could reduce international business and profitability.

Financial & Regulatory Risks

Currency & Financial Risks:

• Foreign Exchange: Exposure to fluctuations in the RMB against the U.S. dollar, affecting reported revenues, earnings, and assets. Limited hedging transactions are available in China, and the company has not entered into any.
• Interest Rate Risk: Exposure to interest rate risk from short-term and long-term borrowings, with some loans subject to variable interest rates.
• Credit & Liquidity: Risk of weak liquidity due to past net cash usage in operating activities and long-aged accounts receivable. Outstanding bank loans ($18,392,331 as of September 30, 2025) pose refinancing risks.
• PRC Capital Controls: PRC government controls on RMB convertibility and capital transfers may restrict the ability of PRC subsidiaries to remit foreign currency for dividends or other payments to the holding company.
• Dividend Restrictions: PRC laws require subsidiaries to set aside statutory reserve funds, which are not distributable as cash dividends, limiting the holding company's access to funds.

Regulatory & Compliance Risks:

• Multi-Jurisdictional Compliance: Operations in China, Hong Kong, British Virgin Islands, Delaware, and Uganda subject the company to diverse and evolving regulatory frameworks.
• Trade Regulations: Potential impact from export controls, sanctions, and trade war impacts.
• Tax Regulations: Risk of being classified as a "Resident Enterprise" of China, leading to unfavorable tax consequences. Uncertainties in interpretation and enforcement of PRC tax laws.
• PRC Government Intervention: The Chinese government exerts substantial influence over business operations, with potential for new, stricter regulations or interpretations without advance notice, which could materially change operations or hinder foreign investment.
• Cybersecurity Review: Although the company does not believe it is currently subject to cybersecurity review by Chinese authorities, new regulations could apply in the future, potentially impacting operations or U.S. listing.
• M&A Rules: Future offerings or acquisitions may require approvals or filings with the China Securities Regulatory Commission (CSRC) or other PRC government authorities, which may be difficult to obtain.
• Labor Laws: Failure to make adequate contributions to employee benefit plans as required by PRC regulations may subject the company to penalties.
• HFCAA: Risk of delisting from Nasdaq if the PCAOB is unable to inspect the company's auditors for two consecutive years, although the current auditor is U.S.-based and not subject to PCAOB inspection for China-based companies.

Geopolitical & External Risks

Country-Specific Risks:

• Political Risk: Changes in political and economic policies of the PRC government could adversely affect overall economic growth in China and demand for products.
• Economic Risk: General economic conditions, natural catastrophic events, and public health crises (e.g., COVID-19) can adversely affect operating results.
• Regulatory Changes: Rapid changes in laws and regulations in China with little advance notice could adversely affect operations.
• Enforceability of Civil Liabilities: Difficulty for shareholders to enforce U.S. judgments against the company or its directors/officers due to assets and personnel being primarily located outside the U.S. and lack of reciprocal enforcement treaties.

Innovation & Technology Leadership

Research & Development Focus: ZK International is committed to R&D to improve existing products and develop new technologies for stainless steel products used in water and gas transmission systems. R&D efforts are integral to the company's competitive advantage and differentiation strategy, focusing on mechanical design, mechatronics, CAD design, mold design, and welding. Quality control is a key aspect of the R&D team's work.

As of the filing date, Zhejiang Zhengkang Industrial Co., Ltd. holds 12 Invention Patents, 25 Utility Model Patents, and 1 Design Patent in China. The company has not been granted patents outside of the PRC, which limits protection for international sales.
• Licensing Programs: Not explicitly mentioned.
• IP Litigation: The filing notes that policing unauthorized use of proprietary technology is difficult and expensive, and litigation may be necessary to enforce or defend patents.

Technology Partnerships: Not explicitly mentioned.

Leadership & Governance

Executive Leadership Team

International Management Structure: The filing does not provide specific details on the international management structure beyond the roles of the executive leadership team.

Board Composition: The board of directors consists of 5 directors, a majority of whom are independent as defined by the Nasdaq Capital Market. As of October 19, 2025, following a resignation, none of the current Audit Committee members meet the criteria of an "audit committee financial expert" as defined by SEC regulations. The Board is actively seeking to appoint a qualified independent director.

Regulatory Environment & Compliance

Multi-Jurisdictional Regulatory Framework: Primary Regulatory Environments:

• People's Republic of China: Subject to PRC laws and regulations including the Product Quality Law, Foreign Exchange Administration Regulations, Company Law, Wholly Foreign-owned Enterprise Law, M&A Rules, Anti-Monopoly Law, Data Security Law, Personal Information Protection Law, Measures for Cybersecurity Review, Trademark Law, Patent Law, Enterprise Income Tax Law, Value-added Tax Law, and Labor Contract Law.

• HFCAA: ZK International is not currently identified under the Holding Foreign Companies Accountable Act (HFCAA). Its current auditor, Fortune CPA, Inc., is headquartered in Orange, California, and is not subject to PCAOB inspection as of the filing date. The previous auditor, ZH CPA, LLC, was subject to PCAOB inspection. Uncertainty exists regarding the ability of auditors to fully cooperate with PCAOB requests for audit workpapers without Chinese authorities' approval, which could lead to delisting if the PCAOB is unable to inspect the company's auditor for two consecutive years.
• CSRC Filing for Overseas Listings: The Trial Administrative Measures of Overseas Securities Offering and Listing by Domestic Companies (effective March 31, 2023) require PRC domestic companies seeking direct or indirect overseas offerings and listings to file with the CSRC. ZK International is not currently required to obtain approval for its existing U.S. listing but may need to for future offshore offerings.

International Tax Strategy:

• Transfer Pricing: PRC tax authorities may challenge transfer pricing arrangements between the company's PRC subsidiaries and other entities.
• Tax Treaties: Dividends from PRC subsidiaries to the Hong Kong subsidiary (ZK Pipe Industry Co., Ltd.) may be subject to a reduced 5% withholding tax rate under the Double Tax Avoidance Arrangement if certain conditions are met, but this is not automatic and requires a tax resident certificate.
• EIT Law: Zhejiang Zhengkang Industrial Co., Ltd. benefits from a preferential Enterprise Income Tax (EIT) rate of 15% as a High and New Technology Enterprise (HNTE) until November 30, 2024. Other PRC subsidiaries are subject to a 25% EIT rate. Dividends to non-PRC resident enterprises are generally subject to a 10% withholding tax.

The company has experienced high employee turnover in its industry.

Currency Management & Financial Strategy

Multi-Currency Operations: Currency Exposure:

Hedging Strategies:

• Transaction Hedging: Not currently utilized.
• Translation Hedging: Not currently utilized.
• Economic Hedging: Not currently utilized. ZK International has not entered into any hedging transactions to reduce its exposure to foreign exchange risk, citing the limited availability and effectiveness of such transactions in China. The value of the RMB against the U.S. dollar is affected by China's political and economic conditions, and while the People's Bank of China intervenes to prevent significant short-term fluctuations, the RMB may appreciate or depreciate significantly in the medium to long term.
