Risk factors and legal proceedings

The risks TANCHENG GROUP CO., LTD. names in Item 1A of its 10-K filed Mar 31, 2026: 36 risks under these headings, as written.3

  • Risks Related to Doing Business in China
  • Because all of the Company’s operations are in China, the Company’s business is subject to the complex and rapidly evolving laws and regulations there. The Chinese government may exercise significant oversight and discretion over the conduct of the Company’s business and may intervene in or influence the Company’s operations at any time, which could result in a material change in the Company’s operations and/or the value of the common stock.
  • If the Chinese government chooses to exert more oversight and control over offerings that are conducted overseas and/or foreign investment in China-based issuers, such action could significantly limit or completely hinder Tancheng Group’s ability to offer securities to investors and cause the value of such securities to significantly decline or become worthless.
  • Changes in China’s economic, political or social conditions or government policies could have a material adverse effect on the Company’s business and operations.
  • Uncertainties with respect to the PRC legal system could adversely affect us.
  • You may experience difficulties in effecting service of legal process, enforcing foreign judgments or bringing actions in China against the Company or its management based on foreign laws.
  • The PRC government has increasingly strengthened oversight in offerings conducted overseas or on foreign investment in China-based issuers, which could result in a material change in our operations and our common stock could decline in value or become worthless.
  • Tancheng Group may rely on dividends and other distributions on equity from our PRC subsidiaries for its cash requirements.
  • Non-compliance with labor-related laws and regulations of the PRC could have an adverse impact on the Company’s financial condition and results of operation.
  • The recent joint statement by the SEC, and an act passed by the U.S. Senate and the U.S. House of Representatives, all call for additional and more stringent criteria to be applied to U.S.-listed companies with significant operations in China. These developments could add uncertainties to our continued trading on the OTC markets, future offerings, business operations, share price and reputation.
  • Fluctuations in exchange rates could have a material and adverse effect on the Company’s results of operations and the value of your investment.
  • Governmental control of currency conversion may limit the Company’s ability to utilize the Company’s revenues effectively and affect the value of your investment.
The other 25 risks
  • Certain PRC regulations may make it more difficult for the Company to pursue growth through acquisitions.
  • PRC regulations relating to the establishment of offshore special purpose companies by PRC residents may subject our PRC resident beneficial owners or our PRC subsidiaries to liability or penalties, limit our ability to inject capital into our PRC subsidiaries, limit our PRC subsidiaries’ ability to increase their registered capital or distribute profits to us, or may otherwise adversely affect us.
  • U.S. regulatory bodies may be limited in their ability to conduct investigations or inspections of the Company’s operations in China.
  • If we are classified as a PRC resident enterprise for PRC income tax purposes, such classification could result in unfavorable tax consequences to us and our non-PRC shareholders.
  • We face uncertainty with respect to indirect transfers of equity interests in PRC resident enterprises by their non-PRC holding companies.
  • The approval of the China Securities Regulatory Commission may be required in connection with the Contribution transaction under PRC law.
  • Risks Related to Our Business and Industry
  • We have a limited operating history, which may make it difficult to evaluate our business and prospects and may not be indicative of our future financial results.
  • Failure to effectively expand our sales and marketing capabilities could harm our ability to increase our customer base and achieve broader market acceptance of our products.
  • Significant competition in our industry could adversely affect our results of operations.
  • We have no business liability or disruption insurance, which could expose us to significant costs and business disruption.
  • Our outsourcing processing model presents several risk factors, including quality control, supply chain, financial, and intellectual property risks.
  • Defects in our products could result in loss of customers, reputational damage, and decreased revenue, facing warranty claims that may arise from defective products.
  • We may not be able to adequately protect our material intellectual property and other proprietary rights, or to defend successfully against intellectual property infringement claims by third parties.
  • The growth of our business may be adversely affected if we do not implement our growth strategies and initiatives successfully or if we are unable to manage our growth or operations effectively.
  • In order to compete, we must attract, train and retain highly qualified employees, and the failure to do so could have a material adverse effect on our results of operations.
  • We are dependent on the continued services and performance of our senior management and other key employees, the loss of any of whom could adversely affect our business, operating results and financial condition.
  • The recreational and tourism projects operate in a competitive industry and their revenues, profits or market share could be harmed if they are unable to compete effectively.
  • Declines in discretionary guest spending and guest confidence, or changes in guest tastes and preferences, could affect the profitability of the recreational business.
  • Risks Related to The Market for Our Common Stock
  • Our common stock is quoted on the OTC market, which may have an unfavorable impact on our stock price and liquidity.
  • We are subject to penny stock regulations and restrictions and you may have difficulty selling shares of our common stock.
  • We do not intend to pay dividends for the foreseeable future.
  • Our largest stockholder holds a significant percentage of our outstanding voting securities and may be able to control our management and affairs.
  • Fulfilling our obligations incident to being a public company, including with respect to the requirements of and related rules under the Sarbanes-Oxley Act of 2002, is expensive and time-consuming, and any delays or difficulties in satisfying these obligations could have a material adverse effect on our future results of operations and our stock price.
  • Compliance with changing regulation of corporate governance and public disclosure will result in additional expenses.
  • Provisions in our charter documents and under Nevada law could discourage a takeover that stockholders may consider favorable.

Legal proceedings

The Company may from time to time become involved in legal proceedings or be subject to claims arising in the ordinary course of its business. Litigation or any other legal or administrative proceeding, regardless of the outcome, is likely to result in substantial costs and diversion of its resources, including its management’s time and attention. As of the date of this Annual Report, the Company is currently not aware of any such legal proceedings or claims that in the opinion of its management will have a material adverse effect on its business, financial condition or operating results.
