Ultra low power chip manufacturer Ambiq Micro (AMBQ.US) applies for IPO in the US, planning to raise 80 million US dollars.

Ambiq Micro, a ultra-low power chip design company based in Austin, Texas, officially disclosed the terms of its initial public offering (IPO) on Monday, July 21st, with plans to list on the New York Stock Exchange under the ticker symbol "AMBQ". According to the prospectus, Ambiq Micro plans to issue 3.4 million shares of common stock, with a price range of $22 to $25 per share. At the midpoint price of $23.5, the company's fully diluted market value is approximately $435 million. Founded in 2010, Ambiq Micro focuses on developing ultra-low power semiconductor solutions for artificial intelligence computing and other applications. Its core competitiveness lies in the self-developed SPOT platform (Sub-threshold Power Optimized Technology), which utilizes a set of patented chip design technologies to allow traditional transistors to operate at ultra-low power states near or below threshold levels. With this technology, Ambiq is able to significantly reduce chip power consumption, especially suitable for AI applications in edge computing scenarios. The company's products include a variety of system-on-chips (SoC) paired with embedded software that supports AI operations, general computing, sensing, storage, security, wireless connectivity, and graphics processing. To date, Ambiq's products have powered over 270 million devices, with 42 million chips shipped in 2024 alone, over 40% of which support AI algorithm operations. According to its disclosed financial data, Ambiq Micro generated $77 million in revenue in the past 12 months ending on March 31, 2025. The proceeds from this fundraising will mainly be used for product development, market expansion, and general operational purposes. In the context of the rapid development of the AI industry, the increasing demand for low-power, high-efficiency chips in edge computing has made Ambiq Micro's technological roadmap particularly critical. Compared to large-scale cloud-based models, Ambiq's solutions are more tailored to end devices such as smart wearables, medical monitoring, and industrial IoT scenarios, providing a natural advantage in power-constrained environments. The Ambiq IPO is being co-led by Bank of America Securities, UBS Investment Bank, Needham & Co., and Stifel. It is expected to be priced and listed for trading in the week of July 28, 2025.
