Unity Q1: Revenue Up, GAAP Loss Widens on Intentional Restructuring; Vector Transition Becomes Key Q2 Test

What happened

Unity Software reported Q1 revenue of $508M, up 17% YoY, and adjusted EBITDA of $138M, but a GAAP net loss of $347M due to $279M in impairment charges tied to the ironSource sunset and planned Supersonic divestiture. The headline 'miss estimates' reflects GAAP earnings, which are distorted by these intentional write-downs as management clears non-strategic assets. Strategic Grow revenue, the core focus, jumped 49% YoY to $279M, driven by the Unity Ad Network on the Vector AI platform, partially offsetting ironSource declines. The critical test comes in Q2, when the ironSource direct-demand shutdown on April 30 fully impacts, and Unity guides Strategic Grow to $302-$306M (+50-52% YoY) with adjusted EBITDA of $130-$135M. The market now watches whether Vector can fill the air-pocket and whether Unity's portfolio reset delivers sustained growth.

Implication

Unity's strategic reset is showing operational cash generation ($66M free cash flow) and improving EBITDA margins, but the ironSource sunset introduces near-term revenue uncertainty. If Q2 Strategic Grow hits the guide, the base case of $30 is achievable; a miss could push the stock toward our $18 bear case. Holders should monitor Q2 print (due August 2026) for confirmation of Vector's ability to sustain growth post-sunset.

Thesis delta

The Q1 report confirms the portfolio reset is progressing—strong Strategic Grow growth and cash generation—but the GAAP loss headline masks the intentional charges. The near-term catalyst remains Q2's first full quarter without ironSource direct demand, and the guide suggests management confidence, but the 10-Q explicitly warns of higher-than-expected attrition. This shifts the call from 'wait and see' to 'Q2 print is the decisive proof point'; we maintain our WAIT rating with a 3-6 month re-assessment window.
