Ambiq Micro, Inc. has successfully closed its upsized initial public offering (IPO), raising a total of $110.4 million. The company sold 4.6 million shares at a public offering price of $24.00 per share, with the underwriters' option to purchase an additional 600,000 shares fully exercised. The shares began trading on the New York Stock Exchange under the ticker symbol "AMBQ" on July 30, 2025 [1].

The IPO, led by BofA Securities and UBS Investment Bank as joint lead book-running managers, marks a significant milestone for Ambiq, a technology leader in ultra-low-power semiconductor solutions for edge AI. The company's mission is to enable intelligence everywhere by delivering the lowest power semiconductor solutions [5].

Ambiq's technology, built on its patented and proprietary subthreshold power optimized technology (SPOT®), offers a multi-fold improvement in power consumption over traditional semiconductor designs. This innovation is particularly relevant for wearable devices and other edge computing applications where power efficiency is crucial [5].

The company's focus on energy-efficient computing chips has drawn significant investor interest, reflected in the strong performance of its shares during the first trading day. Ambiq's shares rose 61% from their IPO price of $24.00, closing at $38.53 [1, 2, 3, 4].

Ambiq's customer base is concentrated, with sales to major tech companies such as Alphabet Inc.'s Google, Garmin Ltd., and Huawei Technologies Co. Ltd. accounting for more than 85% of its revenue in the most recent fiscal year [3, 4]. The company's technology is also expected to power devices like smart glasses, which run speech and image recognition algorithms on devices with very small batteries [3].

Despite the strong IPO performance, Ambiq reported a net loss of $8.3 million on revenue of $15.7 million for the first quarter of 2025, indicating that the company is still in the early stages of its growth trajectory [2]. However, the company's focus on AI-driven growth and its unique technology position it well for future success.
