The company manufactures and trades bamboo-based charcoal products (under the "Charcoal Doctor" brand) and engages in construction materials trading in the U.S. This Form 20-F covers the fiscal year ended December 31, 2025.

Key Financial Metrics (Fiscal Year 2025)

Material Changes vs. Prior Period

• Revenue Decline: Revenue decreased 10.7% to $38.36 million, attributed to reduced demand in the sluggish real estate market affecting household cleaning products.
• Significant Net Loss: The company reported a net loss of $31.04 million, a sharp deterioration from a $3.57 million loss in 2024. This was driven primarily by a $23.14 million impairment charge on long-term investments in mining entities (Libo Haokun and Fuquan Chengwang) due to government prohibitions on mining activities.
• Operating Expenses Surge: General and administrative expenses increased 295.6% to $19.26 million, largely due to a $15.9 million increase in the allowance for credit losses on accounts receivable.
• Discontinued Operations: The company divested its Electric Vehicle (EV) business in May 2025. Results from this segment are now reported as discontinued operations, resulting in a net loss of $0.06 million for the period.
• Acquisition Unwind: An acquisition of Xintong International Trading Co., Ltd. was terminated in December 2025. The company recognized a $4.42 million loss on the refund receivable and recorded a $54.05 million refund receivable asset.

Guidance, Outlook, and Risks

• Listing Compliance: The company received notice from Nasdaq that its closing bid price fell below $1.00 for 30 consecutive days. It has a 180-day compliance period (until September 22, 2026) to regain compliance or risk delisting.
• Internal Controls: Management concluded that disclosure controls and internal controls over financial reporting were not effective as of December 31, 2025. Material weaknesses include a lack of skilled financial reporting personnel, inadequate approval procedures, and lack of segregation of duties.
• China Regulatory Risks: As a PRC-based issuer, the company faces risks related to the Holding Foreign Companies Accountable Act (HFCAA), potential delisting if PCAOB inspections are obstructed, and evolving PRC regulations regarding overseas listings and data security.
• Liquidity: The company maintains a current ratio of 6.6:1 with $33.06 million in cash. However, it relies on dividends from PRC subsidiaries, which are subject to PRC restrictions and statutory reserve requirements.
• Outlook: The company plans to expand into the U.S. construction materials market but notes no assurance of profitability. It intends to retain earnings for operations and does not plan to pay dividends in the foreseeable future.

Investor Verification Checklist

• Investment Impairment: Verify the valuation methodology and recoverability of the $54.05 million refund receivable from the terminated Xintong acquisition.
• Receivables Quality: Assess the collectability of accounts receivable given the $19.88 million allowance for credit losses and the concentration of sales among three major customers (77% of total sales).
• Nasdaq Compliance: Monitor the company's ability to meet the $1.00 minimum bid price requirement by September 2026 to avoid delisting.
• Internal Control Remediation: Track progress on hiring qualified U.S. GAAP personnel and implementing segregation of duties to address material weaknesses.
• Regulatory Filings: Confirm compliance with PRC CSRC filing requirements for overseas listings and any potential cybersecurity review obligations.
