TANH Amends 20-F/A, Highlights China Risks & Corporate Structure

TL;DR

**TANH's 20-F/A screams 'China risk' – proceed with extreme caution, as government intervention could wipe out shareholder value.**

AI Summary

Tantech Holdings Ltd (TANH) filed a Form 20-F/A on September 18, 2025, amending its annual report for the fiscal year ended December 31, 2024. This amendment addresses an SEC comment letter dated September 2, 2025, primarily focusing on risks related to its corporate structure and operations in China. The filing clarifies that TANH is a British Virgin Islands holding company, with a substantial portion of its operations conducted through PRC subsidiaries, and explicitly states that investors do not have direct ownership in these Chinese subsidiaries. The company confirmed it has no Variable Interest Entities (VIEs) and its industries are not currently subject to foreign ownership limitations in mainland China. However, the amendment significantly expands on the legal and operational risks associated with being a China-based issuer, including potential government intervention, changes in PRC laws, and the impact of the Holding Foreign Companies Accountable Act. The filing also includes a revised Report of Independent Registered Public Accounting Firm and updated financial statements, along with new exhibits related to a promissory note dated August 1, 2024, and auditor's consent.

Why It Matters

This 20-F/A filing is critical for investors as it explicitly details the significant and unique risks associated with Tantech Holdings Ltd's (TANH) corporate structure and its substantial operations in China. The clarification that TANH is a BVI holding company and investors do not directly own its PRC subsidiaries underscores the potential for regulatory intervention by the Chinese government, which could materially impact operations and shareholder value. In a competitive landscape where transparency and regulatory compliance are paramount, these disclosures highlight the heightened scrutiny faced by China-based issuers, potentially affecting TANH's ability to raise capital and its market valuation compared to peers with simpler, less risky structures.

Risk Assessment

Risk Level: high — The risk level is high due to the explicit and extensive disclosure of 'Risks Related to Doing Business in China,' which spans multiple pages and details numerous uncertainties. The filing states, 'the PRC government could disallow our holding company structure, which would result in a material change in our operations and the value of such securities could significantly decline or become worthless.' Furthermore, the potential for delisting under the Holding Foreign Companies Accountable Act if the PCAOB cannot inspect auditors for two consecutive years presents a direct and severe threat to investor liquidity and share value.

Analyst Insight

Investors should thoroughly review the expanded 'Risks Related to Doing Business in China' section. Given the explicit warnings about potential government intervention and the risk of securities becoming worthless, a cautious approach is warranted. Consider reducing exposure or avoiding new positions until there is greater clarity on regulatory stability and reduced geopolitical tensions.

FAQ

Risk Factors

• Uncertainty of PRC Legal System and Regulatory Changes [high — legal]: Investors do not have direct ownership in PRC subsidiaries, relying on a BVI holding company structure. Changes in PRC laws, regulations, or their interpretation could invalidate this structure, leading to a material change in operations and potentially rendering the securities worthless. The company explicitly states that the PRC government could disallow its holding company structure.
• Potential Government Intervention and Shifting Foreign Ownership Rules [high — regulatory]: PRC laws and regulations can change rapidly with little notice. Chinese regulatory authorities could alter rules regarding foreign ownership in the company's operating industries. While currently not subject to foreign ownership limitations, future changes could materially impact operations and the value of securities.
• Limited Legal Protections for Investors [medium — legal]: Uncertainties in the enforcement of PRC laws and regulations may limit the legal protections available to Tantech Holdings Ltd and its investors. This could materially and adversely affect the company's financial condition and results of operations, causing the securities to significantly decline in value or become worthless.
• Impact of Holding Foreign Companies Accountable Act [medium — regulatory]: The Holding Foreign Companies Accountable Act (HFCAA) poses a risk to companies listed in the U.S. with operations in China. If the company's auditors are not subject to inspection by the Public Company Accounting Oversight Board (PCAOB) for three consecutive years, its securities could be delisted from U.S. exchanges.
• Reliance on PRC Subsidiaries for Operations [medium — operational]: A substantial portion of Tantech's operations are conducted through its PRC subsidiaries. This reliance creates operational risks, as any disruption or adverse change affecting these subsidiaries directly impacts the company's overall business and financial performance.

Industry Context

Tantech Holdings Ltd operates in industries that are subject to evolving foreign investment regulations in China. While currently not facing direct ownership limitations, the dynamic regulatory landscape for foreign companies in China presents ongoing challenges. The company's reliance on PRC subsidiaries means its performance is closely tied to the operational and regulatory environment within mainland China.

Regulatory Implications

The amendment highlights significant regulatory risks associated with Tantech's China-based operations, including potential government intervention and changes in foreign ownership rules. The company's BVI holding structure, while currently compliant, is subject to the PRC government's discretion and interpretation of laws, posing a substantial risk to investors.

What Investors Should Do

1. Review the expanded 'Risk Factors' section, particularly those related to China operations and corporate structure.
2. Assess the company's reliance on its PRC subsidiaries and the potential impact of regulatory changes in China.
3. Monitor any future communications from the SEC or the company regarding auditor inspections and compliance with the HFCAA.

Glossary

Form 20-F/A

An amendment to a Form 20-F, which is an annual report filed by foreign private issuers with the U.S. Securities and Exchange Commission (SEC). (This filing is an amendment to Tantech's annual report, addressing specific SEC comments.)

British Virgin Islands (BVI) holding company

A company incorporated in the BVI that owns assets or subsidiaries, rather than conducting direct operations itself. (Tantech Holdings Ltd is structured as a BVI holding company, with its primary operations in mainland China.)

PRC subsidiaries

Subsidiary companies incorporated and operating within the People's Republic of China. (A substantial portion of Tantech's business operations are conducted through these entities.)

Variable Interest Entities (VIEs)

A corporate structure used by Chinese companies to bypass foreign ownership restrictions in certain industries, where a foreign entity controls a Chinese operating company through contractual agreements rather than direct equity ownership. (Tantech explicitly states it no longer uses VIEs, but the historical context and potential for future regulatory scrutiny remain relevant.)

Guidance Catalogue for Industrial Structure Adjustments

A regulation in China that historically governed foreign investment restrictions across various industries. (This regulation was previously relevant to Tantech's control of Shangchi Automobile due to foreign ownership limitations in the auto industry.)

Special Administrative Measures (Negative List) for Foreign Investment Access

The current framework in China that specifies industries where foreign investment is restricted or prohibited. (This list now permits full foreign investment in the business conducted by Shangchi Automobile, allowing for direct ownership.)

Holding Foreign Companies Accountable Act (HFCAA)

A U.S. law that can lead to the delisting of foreign companies from U.S. stock exchanges if their auditors are not subject to inspection by the Public Company Accounting Oversight Board (PCAOB) for three consecutive years. (This poses a significant regulatory risk for U.S.-listed Chinese companies, including Tantech.)

Share consolidation

A corporate action where a company reduces the number of its outstanding shares by combining them into fewer shares, typically to increase the per-share market price. (Tantech underwent a one-for-forty share consolidation on February 13, 2025, which adjusted its outstanding share count.)

Year-Over-Year Comparison

This amendment to the Form 20-F for the fiscal year ended December 31, 2024, significantly expands disclosures on risks related to Tantech's corporate structure and operations in China, prompted by an SEC comment letter. While the original filing on May 15, 2025, provided the annual report, this amendment on September 18, 2025, introduces a more detailed discussion of legal and regulatory uncertainties, potential government intervention, and the lack of direct investor ownership in PRC subsidiaries. The company explicitly confirms it has no VIEs and its industries are not currently subject to foreign ownership limitations, a clarification likely driven by the SEC's focus on these structural risks.

KEY INFORMATION Our Corporate Structure and the Operations of Our PRC Subsidiaries Tantech Holdings Ltd ("THL," "we," "our" or "us") is not a PRC operating company but a holding company incorporated in the British Virgin Islands ("BVI"). As a holding company, we conduct a substantial portion of our operations through our subsidiaries based in mainland China. Therefore, investing in our securities involves unique and a high degree of risk. You should carefully read and consider the risk factors of this report (beginning on page 13), especially the risk factors under the caption "Risks Related to Doing Business in China" (beginning on Page 23). The securities registered under the Securities Act and the Exchange Act are of the offshore holding company, Tantech Holdings Ltd, a British Virgin Islands company, which owns equity interests, directly or indirectly, of the operating subsidiaries. Subsidiaries conduct operations in China and the U.S., and the holding company does not conduct operations in China or the U.S. As a holding company with no material operations of its own, the majority of the Company's business is conducted by our PRC subsidiaries with a portion operated by our non-PRC subsidiaries. Investors of our securities do not and may never have direct ownership in our subsidiaries based in China. This holding structure involves unique risks to investors in that the PRC government could disallow our holding company structure, which would result in a material change in our operations and the value of such securities could significantly decline or become worthless. See "Risk Factors — Risks Related to Doing Business in China."
