Despite declining full-year revenue, the significant margin expansion, strong Q4 performance, and raised guidance suggest improving execution and demand for Ambiq's edge AI products. Traders should monitor whether the sequential revenue growth continues into Q1 2026 and whether the company can return to full-year revenue growth while maintaining margin expansion.
