News Summary
NegativeArm delivered strong earnings beats in Q4 FY2026 and Q1 FY2027 with record revenues and royalty growth, while successfully launching its AGI CPU with major partner commitments and $2B demand outlook. However, stock declined after both earnings reports, guidance disappointed relative to expectations, smartphone royalty growth is decelerating, and a material FTC antitrust investigation threatens the core licensing business model.
Red flags
- •FTC formal antitrust investigation into potential CPU monopolization and refusal to license designs to third parties
- •Stock fell 5.6% after Q4 FY2026 beat and 8% after Q1 FY2027 beat due to guidance disappointment
- •Operating margins compressed from 11% to 7% YoY in Q1 despite revenue growth, due to 28% operating expense increase
- •Smartphone royalty headwinds; full-year growth guided toward 'high teens' instead of 20%
- •AGI CPU supply chain uncertainty—manufacturing capacity locked only for initial $1B in orders, not secured for subsequent volumes
- •Qualcomm-initiated complaints also escalated to Korean and EU regulators with prior Korean office inspection
