Unity Software Inc. delivered exceptional Q4 2025 results, exceeding the high end of guidance with Grow revenue of $338 million (up 11% year-over-year) and Create revenue of $165 million (up 16% year-over-year excluding non-strategic revenue). Adjusted EBITDA reached $125 million, representing a 25% margin and a 200 basis point improvement year-over-year, driven by the rapid scaling of the Vector AI platform and disciplined cost management. Vector achieved its third consecutive quarter of mid-teen sequential growth, now representing 56% of Grow revenue, while the legacy IronSource ad network declined to 11% of Grow revenue and is expected to become immaterial by Q1 2026. For the full year 2025, free cash flow grew 41% to over $400 million with a 99% conversion rate. Looking ahead to Q1 2026, the company guides for total revenue of $480-$490 million and Adjusted EBITDA of $105-$110 million, with Vector expected to grow 10% sequentially and achieve a $1 billion annual run rate by the end of the year.

Vector AI Platform Scaling: The primary strategic driver is the rapid displacement of the legacy IronSource ad network by the Vector AI platform. Vector revenue has grown 53% in the first three quarters since launch and is now 56% of Grow revenue. Management emphasized that this shift is not just revenue replacement but a quality upgrade, moving from 'commoditized lower-margin ad network revenue for deeply differentiated AI platform revenue.' This transition is expected to materially enhance growth rates and profitability in 2026, with Vector projected to reach a $1 billion quarterly run rate by year-end.
Runtime Data Integration: A major technological catalyst is the integration of runtime engine data into Vector models, expected to go live in Q2 2026. Management highlighted that they have achieved over 90% opt-in rates for the developer data framework. While Bromberg cautioned this won't be a 'lightning strike moment,' he believes the addition of 'highly behavioral data' will result in 'significant compounding model improvements over time.' This creates a competitive moat by utilizing unique deep behavioral signals (physics, input, networking) that competitors lack.
Democratization via AI and Web: Unity is executing a strategy to expand its addressable market by moving authoring to the web browser and integrating AI tools. The upcoming 'Unity Studio' (browser-based) and 'Unity AI' (natural language game prompting) aim to turn Unity from a tool solely for software developers into a collaboration platform for entire creative teams (artists, designers, PMs). Bromberg stated this will 'massively expanding Unity Software Inc.'s utility and the size of our addressable market' by lowering the barrier to entry for non-coders.
Commerce and Monetization Synergy: The launch of enhanced in-app purchase commerce offerings (GA in Q2 2026) represents a strategic shift to integrate monetization directly into the creation flow. Bromberg noted that while the direct economics of transactions are 'modest,' the strategic value lies in 'optimizing and improving engagement in their games' and feeding data into Vector models to improve ad targeting. This creates a flywheel where better commerce data leads to better ad performance, which drives more ad spend.
China Market Expansion: Unity reported exceptional growth in China, with Create revenue up nearly 50% year-over-year in 2025. This success is attributed to unique interoperability with local platforms like Open Harmony and WeChat. Bromberg highlighted that Unity is the 'global abstraction layer' allowing developers to deploy everywhere, positioning the company to capture growth in the world's largest video game market. This diversification reduces reliance on Western markets and provides a strong foothold for future growth.
IronSource Decline Masking Growth: While management frames the decline of IronSource as a positive shift to higher-quality revenue, the rapid deterioration creates a significant near-term headwind. IronSource revenue declined $7 million sequentially in Q4 and is expected to be less than 6% of total revenue in Q1. This decline is currently masking the true growth potential of the Vector business, as total Grow revenue is only growing 11% YoY while Vector grows much faster. Investors must trust that Vector can scale fast enough to offset this rapid legacy revenue decay.
Competitive Threats and Market Noise: Management spent considerable effort addressing 'consternation' regarding competition from Meta and Google Genie. Bromberg's defensive tone regarding a 'LinkedIn post' about Meta suggests the stock is sensitive to competitive narratives. While Bromberg argues that world models are 'complementary, not duplicative' to game engines, the rapid advancement of generative AI video (like Genie) poses a long-term risk to Unity's 'Create' business if asset generation becomes too good or if competitors build proprietary engines that bypass Unity's runtime.
Execution Risk on Runtime Data: Management guided for runtime data integration in Q2 2026 but explicitly managed expectations down, stating it is 'not a lightning strike moment.' Given the high investor expectations surrounding AI, a slow ramp or incremental improvements in ROAS (Return on Ad Spend) could lead to multiple compression if the 'compounding model improvements' do not materialize quickly enough to satisfy the market.
Q1 Seasonality and Guidance: Q1 guidance implies flat sequential growth for the Grow segment, attributed to seasonality and fewer calendar days. While Vector is expected to grow 10% sequentially, the overall business appears subject to significant volatility and seasonal lumpiness. The guidance for 'double-digit year-over-year revenue growth' in Create excludes non-strategic revenue, suggesting headline GAAP growth might lag operational performance.
Overall: Management exhibited a highly confident and assertive demeanor throughout the call, particularly CEO Matthew Bromberg, who actively dismissed external market concerns regarding competition and legacy business declines. There was a distinct shift from defensive to offensive when discussing the company's AI capabilities and market positioning, with Bromberg repeatedly emphasizing that Unity is just at the 'beginning of the trajectory' for Vector. The tone in prepared remarks was optimistic and focused on long-term transformation, while the Q&A session featured sharp, direct rebuttals to analyst skepticism.
Confidence: HIGH - Management displayed strong conviction backed by specific outperformance metrics (e.g., Vector growing 53% since launch, 90% opt-in rates for runtime data). Bromberg explicitly stated he has a 'difficult time understanding' market skepticism and rejected the idea of a 'natural ceiling' for their ad business, indicating high internal confidence in the product roadmap.
$480 million to $490 million
$105 million to $110 million
10% Sequential Growth
Comfortably more than $1 billion per year
Less than 6% of total revenue
Hedging & Uncertainty: Management used specific hedging regarding the timeline and immediate impact of new technologies, particularly around runtime data and AI. Bromberg used phrases like 'we don't anticipate that the inclusion of runtime data will produce a lightning strike moment, but rather it's our conviction that the addition of highly behavioral data will result in significant compounding model improvements over time.' This language tempers immediate expectations while maintaining long-term enthusiasm. Similarly, regarding AI, he used 'we believe' and 'our bet is' to frame strategic outlooks as calculated probabilities rather than certainties. However, hedging was notably absent regarding current performance metrics, where language was definitive ('comfortably exceeded,' 'exceptional performance').

Analyst Sentiment: Analysts expressed skepticism regarding the sustainability of Vector's growth versus the decline of IronSource, and probed heavily into competitive threats from Meta and Google Genie. There was clear concern about the 'end state' of game development in an AI world and how Unity's moat holds up.
Management Responses: Matthew Bromberg responded with high confidence and a touch of defensiveness, explicitly calling out 'consternation' and 'LinkedIn posts' as noise. He reframed competitive threats (Meta, Genie) as complementary opportunities, emphasizing Unity's unique position as the 'assembly point' for interactive content. Jarrod Yahes provided detailed financial backing to the growth narrative, focusing on margin expansion and cash flow.
Vector vs. IronSource Mix: Analysts sought clarity on how much of Vector's growth is organic versus cannibalization of IronSource. Management insisted Vector growth is driven by incremental demand and improved ROAS.
Competitive Landscape (Meta/Genie): Multiple questions addressed whether Meta's increased iOS competition or Google's Genie model threatens Unity's core engine or ad business. Bromberg argued these are complementary or irrelevant to Unity's specific focus on games.
Commerce Monetization: Analysts asked about the revenue potential of the new in-app purchase tools. Management clarified the economics are 'modest' but the strategic value lies in data and customer stickiness.
Runtime Data Impact: Questions focused on the tangible contribution of runtime data integration. Management emphasized it is a long-term compounding improvement rather than a short-term spike.
Unity is undergoing a significant quality transformation, successfully pivoting from a legacy ad network business to a high-growth AI platform (Vector). The Q4 results demonstrate that the core business is stabilizing and re-accelerating, with Create growing 16% and Vector growing mid-teens sequentially. The integration of runtime data into Vector in Q2 2026 represents a proprietary data moat that competitors cannot easily replicate, potentially driving sustained outperformance in ROAS. Furthermore, the expansion of the engine to the browser and the integration of AI authoring tools position Unity to capture a much larger share of the value chain in game development. While the decline of IronSource creates a near-term headwind, the shift to higher-margin AI revenue and the 41% growth in FCF demonstrate strong operational discipline. The risk of AI commoditizing asset creation is mitigated by Unity's 'assembly point' strategy, making the stock attractive at this inflection point.
Management views AI as a massive tailwind that will increase leisure time and lower the cost of game creation, expanding the total addressable market for interactive content.
Unity is experiencing robust growth in China (Create up 50%), driven by compatibility with local platforms like Open Harmony and WeChat, serving as a hedge against Western market saturation.
The ad tech landscape remains fiercely competitive with Meta and Applovin. Management acknowledged Meta's competitiveness on iOS but downplayed its impact, attributing Vector's success to superior ROAS and focus on the gaming vertical.
