Watch list
What moves the thesis, sorted by direction.
AI power crunch
Oracle powered a Utah site in under two months and AEP is deploying 700 MW for Google. Backlog is growing faster than revenue, and capacity is nearing 5 GW a year with more room in Fremont.
Profitable growth
Non-GAAP operating income was $286M in Q3, more than all of 2025; full-year guidance is now $960M–1.03B with EPS of $3.10–3.40.
Working capital and margin
Free cash flow was −$181M in Q3 as unbilled contract assets doubled to $859M and capex tripled to $153M. Margin guidance stayed at ~34% despite the revenue raise, on ramp and expediting costs.
Valuation and volatility
About 47× next year's consensus earnings with a beta near 3.8; shares fell 8.7% on report day and further after hours despite the beat.
