TANCHENG GROUP CO., LTD. Undergoes Significant Auditor Change Amidst Financial Concerns

Here's an updated look at the recent material event concerning TANCHENG GROUP CO., LTD., designed to give you a clearer picture of what's happening and why it matters for your investment decisions.

1. Event Description (what happened)

TANCHENG GROUP CO., LTD. recently announced a critical change in its independent auditor, signaling significant underlying challenges and strategic shifts. Effective February 27, 2026, the company's Board of Directors appointed Guangdong Prouden CPAs GP as its new auditor, replacing Onestop Assurance PAC. The company officially filed this decision with regulators on February 28, 2026.

This change is far from routine. It follows two consecutive years (2023 and 2024) during which the former auditor, Onestop Assurance, issued highly concerning opinions about TANCHENG GROUP's financial health and internal controls.

Key Issues Identified by the Former Auditor:

1. "Substantial Doubt About the Company’s Ability to Continue as a Going Concern": This severe warning means Onestop Assurance had significant reservations about TANCHENG GROUP's long-term viability. While the filing didn't detail specific financial metrics (like sustained operating losses, negative cash flows, or significant debt maturities), investors should understand this implies a precarious financial position.
2. "Material Weaknesses in Internal Control Over Financial Reporting": This indicates serious flaws in how the company manages its finances, records transactions, and safeguards its assets. The filing highlighted two critical areas:
   • Inadequate Oversight: Before October 2023, the company operated with only one director and executive officer, creating a lack of proper checks and balances. Currently, the company still lacks a dedicated Audit Committee composed of independent financial experts. Instead, the full Board of Directors serves as the Audit Committee, but without independent members, its oversight capabilities are compromised.
   • Poor Data Security: The company lacked formal procedures for backing up critical financial data or storing it securely off-site, exposing its financial records to significant risk of loss or compromise.

Crucially, both TANCHENG GROUP and Onestop Assurance PAC confirmed no disagreements regarding specific accounting principles, financial statement disclosures, or audit scope. This suggests the auditor change stemmed from fundamental concerns about the company's operational and financial integrity, rather than disputes over specific numbers.

TANCHENG GROUP's Stated Remediation Plan:

TANCHENG GROUP has outlined preliminary steps to address these critical findings and restore investor confidence:

• Strengthening Governance: The company plans to actively recruit and appoint additional independent directors to its Board. A key focus is establishing a fully independent Audit Committee with members who have relevant financial expertise. This committee will provide robust oversight of financial reporting and internal controls.
• Enhancing Data Security: TANCHENG GROUP plans to implement formal, comprehensive data backup protocols, including regular off-site storage, to protect its vital financial information.
• Addressing Going Concern: Although specific financial strategies were not detailed, the company expects to pursue initiatives to improve its liquidity, profitability, and overall financial stability. These efforts aim to alleviate the "going concern" doubt and could involve cost-cutting, revenue generation, or seeking additional financing.

2. Event Date/Timeline

• February 27, 2026: Effective date of the Board's appointment of Guangdong Prouden CPAs GP as the new auditor.
• February 28, 2026: Official filing date of the auditor change with regulators.
• 2023 and 2024: Years the former auditor, Onestop Assurance, issued concerning opinions on TANCHENG GROUP's financial health and internal controls.
• Prior to October 2023: Period when the company operated with only one director and executive officer, contributing to inadequate oversight.

3. Impact Assessment (who/what is affected)

This auditor change, combined with the serious issues raised, carries significant implications for the company's operations, financial reporting, and investor perception.

• Company Operations and Governance: The company's ability to operate effectively and maintain robust internal controls is directly affected. This requires significant remediation efforts in governance structure (Board and Audit Committee composition) and data management.
• Financial Reporting Reliability: Material weaknesses in internal controls undermine the reliability and trustworthiness of the company's financial statements, making it harder for stakeholders to assess its true financial health.
• Investor Confidence: The "going concern" warning fundamentally questions the company's long-term operational ability, significantly increasing investment risk and potentially eroding investor confidence.
• Regulatory Scrutiny: The SEC and other regulators will closely monitor TANCHENG GROUP's progress in addressing these issues. Ineffective remediation could lead to potential consequences.

4. Financial Impact (if applicable)

The primary financial impact stems from the "going concern" warning and the "material weaknesses in internal control over financial reporting."

• Precarious Financial Position: The "going concern" warning implies a precarious financial position, suggesting potential issues like sustained operating losses, negative cash flows, or significant debt maturities. While the filing didn't detail specific financial metrics, it implies a heightened risk to the company's long-term financial viability.
• Cost of Remediation: Addressing the identified material weaknesses (e.g., recruiting independent directors, implementing new data security systems) will incur costs for the company.
• Potential for Volatility: This news often leads to increased stock price volatility as the market digests the implications of the auditor change and underlying financial concerns.
• Impact on Financing: The "going concern" doubt could make it more challenging or expensive for the company to secure additional financing, if needed.

5. Key Takeaways for Investors

This period is crucial for TANCHENG GROUP to demonstrate its commitment to robust financial governance and operational stability. Investors should approach this situation with caution, seeking clear evidence of effective remediation before making long-term investment decisions.

• Increased Risk Profile: The "going concern" warning fundamentally questions the company's long-term operational ability, significantly increasing investment risk.
• Trust and Transparency: Material weaknesses in internal controls undermine the reliability of the company's financial statements, making it harder for investors to trust reported figures.
• Regulatory Scrutiny: The SEC will closely monitor TANCHENG GROUP's progress in addressing these issues. Ineffective remediation could lead to potential consequences.
• Potential for Volatility: This news often leads to increased stock price volatility as the market digests the implications.

What's Next for Investors:

• New Auditor's Role: Guangdong Prouden CPAs GP will now audit TANCHENG GROUP's financial statements for the upcoming fiscal year, providing a fresh perspective on the company's financial health and controls.
• Future Disclosures: Investors should closely monitor TANCHENG GROUP's next financial reports (e.g., quarterly and annual filings) for concrete updates on its remediation efforts. Look for specific details on new independent director appointments, the Audit Committee's formation, and progress in improving data security.
• Resolution of Going Concern: The most critical update will be whether the new auditor's report continues to include a "going concern" qualification, and what specific actions the company has taken to improve its financial viability.
