Ambiq Micro, Inc. (AMBQ) is a Technology stock trading at $57.73 (as of 2026-08-20), with a market capitalization of $1.23B. Figures are sourced from first-party U.S. SEC EDGAR filings and market data.

Ambiq Micro, Inc. designs ultra-low-power integrated circuits and related subthreshold, power-optimized technologies, including low-power real-time clock and microcontroller products, for devices such as wearables, smart cards, wireless sensors, and IoT. It also provides SoC offerings for edge AI acceleration and sells its products through sales representatives, with technical support for customers.

Understand Ambiq Micro, Inc.: how it makes money

Ambiq Micro develops ultra-low-power integrated circuits for power-sensitive applications like wearables, smart cards, wireless sensors, and IoT products, and it makes money by selling chips such as Apollo (an edge AI system-on-a-chip) and Atomiq (AI acceleration with new memory innovations).

The core profit driver is converting adoption of Ambiq's ultra-low-power edge AI chips (Apollo and Atomiq) into chip sales volume, since the latest quarter shows strong gross margin (43.5%) but a deeply negative operating margin (-46.6%) when revenue is still very small in this dataset.

Revenue by segment (latest quarter)
Net Sales$0.0B

Business quality (Weak): Technology and product focus are clear (Apollo and Atomiq), and operating loss is material in the latest quarter, so investor attention should center on whether adoption translates into larger, more diversified, repeat sales.

Valuation: At 6× earnings, AMBQ trades 88% below the Semiconductors average (51×). Note: one-time items can distort reported P/E.

Bull case

  • Product adoption indicator: Units Shipped Running Artificial Intelligence Algorithms is 80%, suggesting a large share of shipments are used for AI-capable workloads.
  • Technology positioned for power-sensitive markets: Ambiq targets wearables, smart cards, wireless sensors, and IoT, supported by Apollo (edge AI SoC) and Atomiq (AI acceleration with memory innovations).

Bear case

  • Operating profitability remains weak: Operating margin is -46.6% in the latest quarter, even though gross margin is 43.5%, indicating costs are outweighing gross profit.
  • Customer concentration risk: Top Three Customer Concentration is 71.0%, which increases risk if a major customer reduces orders.
