• The company may be subject to PRC regulatory review and disclosure requirements, government interference, or restrictions on offering securities and raising capital outside China.
• The company faces risks related to cybersecurity and data protection laws in the PRC, with potential for material adverse effects on business, financial condition, and operating results.
• The company may require additional financing in the future, which may be costly, difficult, or impossible to obtain, potentially diluting shareholder equity or increasing debt service obligations.
• The company's business is subject to intense competition for users, usage time, advertising customers, technology, and skilled employees.

Future Outlook

The company intends to continue its balanced development approach between growth and profitability by focusing resources on more profitable businesses, particularly pan-entertainment mobile applications in overseas markets, and implementing cost-control initiatives. However, future trends in DAUs, MAUs, and revenues are uncertain and depend on various factors including market acceptance, competition, and the regulatory environment. The company may require additional capital for future business expansion.

Management Comments

• We have implemented a balanced development approach between growth and profitability by continuous transition of the strategy in relation to the acquisition of new users and the retention of existing users.
• We plan to continue to invest in the development of innovative products catering to users interests and demands in order to create more advertising spaces.
• We believe that our current cash, cash equivalents and restricted cash, the available credit under our existing credit facilities, and our anticipated cash flows from operations will be sufficient to meet our anticipated working capital requirements and capital expenditures in the ordinary course of business for the next 12 months.
• We believe that the termination of the Deposit Agreement will not have a material adverse impact on its operations or financial position.

Industry Context

StockSavvy.ai notes that CooTek's significant revenue decline and net loss in 2025 reflect broader challenges in the mobile internet and advertising sectors, particularly for companies operating in China. The shift towards in-app purchases as a primary revenue driver, while increasing gross margin potential, has not offset the overall revenue contraction. The company's strategic focus on overseas markets and cost-control measures are critical for navigating the current economic and regulatory landscape.

Comparison to Industry Standards

• CooTek's gross margin of 70.2% in 2025 is generally in line with or slightly below industry averages for mobile application developers that rely heavily on in-app purchases, which often have higher platform fees compared to advertising-based models.
• The company's significant reduction in sales and marketing expenses (45.0% of revenue) compared to previous years (55.3% in 2023) suggests a move towards more efficient user acquisition, a trend seen in the industry as user growth becomes more challenging.
• The substantial decrease in DAUs and MAUs (average DAUs for pan-entertainment applications fell to 0.4 million in December 2025 from 1.9 million in December 2023) indicates a significant contraction in user engagement, which is a key performance indicator across the mobile app industry.
• The company's net loss and negative working capital, leading to substantial doubt about its going concern status, is a critical concern that is not typical for healthy companies in the industry, highlighting significant operational and financial challenges.
• The termination of its ADS program and delisting from OTC Pink signifies a severe reduction in liquidity and access to capital markets, a situation not commonly faced by established players in the mobile app and gaming sectors.

Corporate Governance

Legal Proceedings

• A lawsuit initiated by a cloud services provider seeking return of preferential discounts and alleged liquidated damages under a service agreement is pending.
• In August 2021, Molihong was fined and ordered to confiscate illegal earnings for providing online publication without a license and for online pornography publication on Fengdu Novel.

Related Party Transactions

• An executive officer provided unsecured, interest-free loans totaling US$0.4 million as of December 31, 2025, to support working capital.
• The company holds a 4% partnership interest in a privately held investment limited partnership through an equity nominee arrangement with the same executive officer, with a carrying amount of US$0.3 million as of December 31, 2025.

Stakeholder Impact

• Shareholders face significant risks due to the company's going concern issues, revenue decline, net loss, and the termination of its ADS program, potentially impacting the value and liquidity of their investments.
• Employees may be affected by cost-control measures, including potential reductions in sales and marketing expenses and R&D staff.
• Creditors and lenders may face increased risk given the company's financial condition and reliance on short-term borrowings and potential future financing.
• Business partners, including advertisers and platform providers, may be impacted by the company's reduced scale of operations and potential financial instability.

Next Steps

• Continue implementing cost-control initiatives to improve cost and expense efficiency.
• Focus resources on more profitable businesses, particularly pan-entertainment mobile applications in overseas markets.
• Seek external financing to improve liquidity position and fund continuing operations.
• Renew short-term bank borrowings if needed and seek additional credit facilities from more financing banks.

Key Dates

Recommendation

The company's deteriorating financial performance, including a significant revenue decline, net loss, and substantial doubt about its going concern status, coupled with the termination of its ADS program and delisting from OTC Pink, presents a high-risk investment profile. The lack of independent directors and ongoing regulatory risks in China further exacerbate these concerns, making a sell recommendation appropriate for seasoned investors.
