Performance Analysis

Unity’s Q3 featured a decisive acceleration in its Grow segment, with Vector AI, Unity’s machine learning-powered ad optimization platform, driving an 11% sequential revenue increase.

The Create segment, which encompasses Unity’s engine and subscription software, also delivered, with underlying subscription revenue up 13% year over year after adjusting for non-strategic revenue. China was a standout contributor, now representing 20% of total revenue, up from 15% a year ago, reflecting both Create and Grow segment tailwinds in the region.

Profitability also improved, with adjusted EBITDA margin reaching 23%, a 200 basis point increase year over year, as Unity maintained cost discipline and leveraged automation. Free cash flow hit a record, reflecting the company’s restructuring efforts and high-margin incremental revenue. Unity’s model is showing operating leverage, with high gross margins (82-83%) and fixed costs in cost of goods sold enabling strong cash conversion.

• Grow Segment Outperformance: Vector AI’s rapid adoption and effectiveness led to a $30 million sequential revenue increase, driving incremental high-margin growth.
• Create Segment Acceleration: Price increases, China momentum, and industry adoption boosted subscription revenue; Unity 6 downloads surged 42% quarter over quarter.
• Cash Flow Strength: Record free cash flow of $151 million, up $36 million YoY, underscored Unity’s cash-generative profile.

Unity’s financial trajectory now reflects both product innovation and disciplined cost management, with management signaling further upside from AI-driven automation and scale efficiencies heading into 2026.

Executive Commentary

Strategic Positioning

1. Vector AI as Growth Engine

Vector AI, Unity’s proprietary ad optimization platform, is now the primary driver of Grow segment performance. Its capacity to learn from real-time, high-volume behavioral data has enabled broad-based improvements in ad effectiveness, with management highlighting scalability across all customer types and game genres. The roadmap includes leveraging unique runtime data, which is expected to further differentiate Vector and begin impacting financials in 2026.

2. Create Segment Transformation and China Penetration

The Create segment, Unity’s core engine and subscription business, is benefiting from price increases, improved product quality, and strong adoption in China. Unity 6’s rapid uptake (9.4 million downloads, up 42% QoQ) and the launch of the Developer Data Framework are increasing stickiness and value for developers. China’s share of revenue rose to 20%, with Unity uniquely positioned to serve all major local platforms and automakers, reinforcing its status as a horizontal platform provider.

3. Cross-Platform Commerce and Ecosystem Expansion

Unity IAP, the new in-app purchase platform, enables developers to manage global commerce and catalogs across multiple payment providers from a single dashboard. While currently a value-add, management sees long-term monetization potential as app stores open and developers seek alternative commerce solutions. Unity’s partnerships with Stripe and Coda, and ongoing discussions with other payment providers, signal a strategy to embed Unity deeper into the monetization stack of the global gaming ecosystem.

4. Margin Structure and Cost Discipline

Unity’s cost structure is evolving, with automation and AI driving operating leverage. High gross margins, fixed cost leverage, and disciplined SG&A and G&A spending have enabled margin expansion even as cloud costs (second-largest expense) grow with usage. Management expects continued margin gains as revenue scales, with the potential to reinvest in high-return product initiatives.

5. Broader Platform Ambitions and Programmatic Ads

Unity is extending its platform reach, with initiatives in programmatic advertising (Audience Hub) and support for emerging platforms (Android XR, AR/VR). Management sees long-term opportunity in non-gaming advertising, leveraging Unity’s horizontal reach and privacy-safe data to attract brand advertisers. These moves position Unity as a foundational infrastructure provider for interactive content beyond gaming.

Key Considerations

Unity’s Q3 results reflect a business model pivoting from cyclical recovery to structural growth, as data-driven products and disciplined cost management converge. The company’s positioning at the intersection of creation, discovery, and monetization is being reinforced by:

Key Considerations:

• Vector AI’s Moat: Ongoing improvements and the upcoming integration of runtime data are set to deepen Vector’s competitive advantage and revenue contribution.
• China’s Expanding Contribution: With 20% of revenue now from China, Unity’s seamless integration with local platforms and automakers is accelerating growth and market share.
• Cross-Platform Commerce Opportunity: Unity IAP and partnerships with Stripe and Coda position the company to capture value as app store ecosystems open globally.
• Margin Expansion Levers: High fixed costs, automation, and cloud efficiency gains support a structurally higher margin profile as revenue scales.
• Programmatic and Non-Gaming Ad Initiatives: Audience Hub and other moves into programmatic advertising offer incremental growth vectors and platform diversification.

Risks

Unity’s forward trajectory is not without risk: The pace of adoption for new products like Unity IAP and the integration of runtime data into Vector remains uncertain and could lag expectations. Cloud cost inflation, regulatory headwinds in global app commerce, and intensifying competition from both gaming and non-gaming platforms could pressure margins or slow growth. Management’s guidance reflects confidence, but investors should monitor execution on AI and automation initiatives as well as the sustainability of China-led growth.

Forward Outlook

For Q4 2025, Unity guided to:

• Total revenue of $480 million to $490 million
• Adjusted EBITDA of $110 million to $115 million

For full-year 2025, management maintained a focus on:

• Mid single-digit sequential Grow segment growth, with Vector AI as the primary driver
• Steady Create segment revenue growth, led by subscriptions and China momentum

Management highlighted several factors that will impact Q4:

• Unite global user conference driving known expense items
• End-of-year salesforce accelerators tied to strong Create bookings

Takeaways

Unity’s Q3 marks a clear inflection, with data-driven products and operating leverage translating into improved revenue growth, margin expansion, and free cash flow. The company’s strategic investments in AI, global commerce, and horizontal platform capabilities are deepening its moat and expanding its addressable market.

• Vector AI’s scalability and upcoming runtime data integration are set to sustain Grow segment outperformance, providing a durable growth engine.
• Create segment momentum, especially in China, is diversifying revenue and reinforcing Unity’s horizontal platform strategy.
• Margin expansion and cash flow strength give Unity ample flexibility, but execution on new product rollouts and international growth will determine the pace and durability of the inflection.

Conclusion

Unity’s third quarter validated its transition to a data-driven, platform-centric business model, as Vector AI and subscription momentum combined with disciplined cost management to deliver both growth and profitability. The company’s deepening platform integration and expanding global reach position it for sustained upside, though execution risks around new product adoption and competitive pressures remain key watchpoints.
