Outlook is supported by AI-driven demand and a $25B revenue target by FY31, but high valuation and smartphone market headwinds pose risks.

The company reported strong Q2 2026 earnings, beating estimates with EPS of $3.12 and raising its full-year outlook, driven by robust testing demand. Revenue grew to $11.04B in 2025, with net income of $992M, though margins face pressure from lower-margin deals and rising costs.
