The blunt verdict
Unity is two businesses: Create, the game engine sold as subscriptions, and Grow, the mobile ads business rebuilt around the Vector AI platform. Both were broken in different ways, Create by the 2023 Runtime Fee disaster and Grow by a bloated ironSource inheritance. Since May 2024, CEO Matthew Bromberg has fixed the engine's trust problem, killed the bad ads assets, and expanded adjusted EBITDA margins from about 19% to 29% in six quarters. The investment question is whether that margin can reach the high 30s by FY2029 while revenue compounds in the mid teens. The evidence says yes, if Vector keeps scaling and the cost base stays reset. But at 36 times trailing adjusted EBITDA, the market already assumes the leverage story plays out, so the base-case return is a modest +29% and the bear case is a genuine -68%.
The business engine
Create Solutions is the subscription engine: engine seats (Pro, Enterprise, Industry) plus cloud services, about $157M of strategic revenue a quarter, growing roughly 14% excluding a prior-year item. Grow Solutions is the volatile engine: mobile advertising on Vector plus LevelPlay mediation, about $329M of strategic revenue a quarter, up 63%. Management splits revenue into strategic (the businesses it is keeping, up 38% in Q2) and non-strategic (the legacy pieces being wound down, guided to about $20M in Q3). One disclosure gap to respect: Unity does not report gross margins separately for Create and Grow, so the margin math in this report is built at the consolidated level.
The operating-leverage bridge: 29% to 37%
This is the core of the thesis. The FY2029 base case assumes a 37% adjusted EBITDA margin, bridged from Q2 2026's 29% in three pieces: Create pricing and subscription mix (+2 points, from the Pro and Enterprise price increases flowing onto a fixed R&D base), the exit of low-quality non-strategic revenue plus Vector and Grow scale (+2 points), and opex leverage on the reset cost base (+4 points, the largest piece and the most evidence-backed: adjusted sales and marketing and G&A already fell in absolute dollars in Q2 2026 while revenue grew 24%). Stock-based compensation, down from 32.9% of revenue in FY2024 to 14.6% in Q2 2026, helps GAAP profitability but is not double-counted in the bridge, since adjusted EBITDA already excludes it.
Vector and the Grow rebuild
Vector grew 23% sequentially in Q2 against management's 12-13% expectation, passed a $1B annualized run rate two quarters ahead of plan, and nearly tripled Day 28 campaign spend sequentially, with Day 28 ROAS adoption above 25% of the ad base. Late in the quarter, runtime data from about 3B monthly consumers began feeding Vector's live models. The ironSource cleanup is nearly done: the legacy Ads Network shut on April 30, 2026, Supersonic was sold to Tripledot in August 2026, and LevelPlay mediation was kept. The honest competitive read: AppLovin remains the leader in mediation and operates at 80%+ EBITDA margins; Unity is the challenger here, not the incumbent.
Meta Connect 2026: modestly positive, not a catalyst
Meta's September 23 keynote announced VR glasses for spring 2027 at $1,299.99 with Quest catalog compatibility, which expands the hardware base for Unity-built XR content, but no new Quest headset and no Unity-specific partnership. Meta's Horizon-native tooling competes only for low-complexity creators. The read-through is modestly positive to neutral: XR optionality intact, not a standalone catalyst, and the FY2029 model does not depend on it.
Balance sheet and the convert calendar
Net cash of about $115M ($2.352B of cash against $2.237B of converts) is a genuine repair, but the maturities need watching: $558M of 2026 notes to be repaid from cash in November 2026, $1B of 2027 notes (2% coupon, converting at $48.89) that either convert to equity if the stock cooperates or get repaid from cash, and $690M of 2030 notes (0% coupon, converting at $36.15) already in the money at $44.10. In the base case the 2027 notes convert; in the bear case they are a liquidity event.
Technical setup: momentum intact, extended
The stock is up roughly 96-136% over six months and sits about 29% above its 200-day average, with the February 2026 low of $16.78 looking like a completed bottom. The $41-44 zone has been month-long congestion; a clean break above $44-45 opens a run at the $52.15 52-week high, while failure to hold $41 exposes the 200-day near $34. Six months of near-doubling means the easy part of this chart is behind it: buy pullbacks, do not chase.
The ruler: valuation and FY2029 targets
At $44.10, Unity trades at about 9.6x trailing revenue and 36x trailing adjusted EBITDA, a full price that only makes sense if FY2029 EBITDA is roughly double today's. Targets use an EV / adjusted EBITDA framework: bear $14 (-68%, Vector stalls, margins settle in the low 20s, 12x multiple), base $57 (+29%, revenue compounds at about 16% to $3.4B, margin reaches 37%, multiple compresses from 36x to 20x as earnings compound), bull $93 (+111%, Vector sustains, enterprise becomes material, 40% margins, 24x). The base return is modest because the starting price already underwrites most of the recovery.
Risks and kill criteria
Principal risks: Vector deceleration, a mobile-ad downturn hitting the highest-margin revenue line, continued AppLovin mediation dominance, Create seat churn or poor price elasticity, the cost base reaccelerating, the $1B 2027 convert maturity, ongoing SBC dilution, and above all expectations: at 36x trailing EBITDA a single weak Vector quarter could cost 20-30% quickly. Kill criteria: Vector sequential growth stalling for two quarters, strategic Grow growth falling below 20%, or opex growing faster than revenue would break the leverage thesis outright.
