This is reflected in the continued growth of our AI-related business revenue, highlighting our steady progress in commercialization and accelerated deployment. Meanwhile, demand for AI-native applications in consumer scenarios continued to rise, driving the scaled application of Physical AI in real-life settings.

AI application & others revenue continued to outperform, increasing by 16.9% year over year and serving as an important driver of our structural growth, driven by continued expansion of cloud-based software offerings with AI application functions and application-level commercialization.

Meanwhile, profitability continued to improve, with GAAP operating margin reaching 9.2% and non-GAAP operating margin standing at 10.0%, demonstrating continued operating leverage and disciplined cost management.

Business Outlook

The overall operating environment remains complex, while continuing to show signs of normalization. Participants across the value chain – including manufacturers, brands, and channel partners – are maintaining a cautiously optimistic to planning. At the same time, we have observed more normalized project execution and continuous demand recovering across several of our core categories, suggesting that the market is gradually moving from adjustment toward a more stable operating rhythm.

Meanwhile, global AI development is entering a new stage of application-led growth. As AI technologies continue to evolve from foundational capabilities toward real-world deployment, enterprises and consumers are increasingly focused on practical use cases, scalable implementation, and scenario-based integration with physical devices. This trend is accelerating the convergence of AI and smart hardware, and is creating new opportunities for application innovation, product expansion, and ecosystem collaboration across a wide range of verticals.

Against this backdrop, Tuya continues to advance its AI-driven strategy by strengthening its AI developer platform, expanding application-level capabilities, and supporting broader deployment across diverse smart device and industry scenarios. The ongoing evolution of AI applications, together with its platform capabilities, ecosystem strengths, and global developer base, will continue to support the creation of diversified, higher-value opportunities over the long term.

In this environment, the Company will continue to maintain disciplined execution while selectively investing in AI-driven applications, platform capabilities, and ecosystem development. In response to this evolving market environment, the Company will continue to iterate and improve its products and services, enhance both software and hardware capabilities, and further support customers and developers in bringing AI-driven applications into practical deployment. At the same time, the Company recognizes that its future trajectory may continue to be influenced by a range of external factors, including shifts in consumer demand, regional economic divergence, inventory dynamics, foreign exchange and interest rate volatility, tariffs and trade policy adjustments, and broader geopolitical uncertainties.

Use of Non-GAAP Financial Measures

In evaluating the business, the Company considers and uses non-GAAP financial measures, such as non-GAAP operating expenses, non-GAAP profit from operations (including non-GAAP operating margin), non-GAAP net profit (including non-GAAP net margin), and non-GAAP basic and diluted net profit per ADS, as supplemental measures to review and assess its operating performance. The presentation of non-GAAP financial measures is not intended to be considered in isolation or as a substitute for the financial information prepared and presented in accordance with generally accepted accounting principles in the United States of America (“U.S. GAAP”). The Company defines non-GAAP financial measures by excluding the impact of share-based compensation expenses from the respective GAAP financial measures. The Company presents the non-GAAP financial measures because they are used by the management to evaluate its operating performance and formulate business plans. The Company also believes that the use of the non-GAAP financial measures facilitates investors’ assessment of its operating performance.

Non-GAAP financial measures are not defined under U.S. GAAP and are not presented in accordance with U.S. GAAP. Non-GAAP financial measures have limitations as analytical tools. One of the key limitations of using the aforementioned non-GAAP financial measures is that they do not reflect all items of expenses that affect the Company’s operations. Share-based compensation expenses have been and may continue to be incurred in the business and are not reflected in the presentation of non-GAAP measures. Further, the non-GAAP financial measures may differ from the non-GAAP information used by other companies, including peer companies, and therefore their comparability may be limited. The Company compensates for these limitations by reconciling the non-GAAP measures to the most directly comparable U.S. GAAP measures, all of which should be considered when evaluating the Company’s performance. The Company encourages you to review its financial information in its entirety and not rely on a single financial measure.

Reconciliations of Tuya’s non-GAAP financial measures to the most comparable U.S. GAAP measures are included at the end of this press release.
