Ultra-low power chip maker Ambiq Micro (AMBQ.US) applies for a US stock IPO to raise US$80 million

The Zhitong Finance App learned that Ambiq Micro, an ultra-low power chip design company headquartered in Austin, Texas, USA, officially disclosed initial public offering (IPO) terms on Monday (July 21) and plans to list on the New York Stock Exchange under the stock code “AMBQ”.

According to the prospectus, Ambiq Micro plans to issue 3.4 million common shares, with a pricing range of $22 to $25 per share. At a median price of $23.5, the company's fully diluted market value is approximately $435 million.

Ambiq Micro was founded in 2010 to develop ultra-low power semiconductor solutions for artificial intelligence computing and other applications. Its core competency lies in the self-developed SPOT Platform (Sub-Threshold Power Optimized Technology), which uses a set of patented chip design techniques to enable traditional transistors to operate at extremely low “sub-threshold” or “near threshold” power consumption.

With this technology, Ambiq can drastically reduce chip power consumption, and is particularly suitable for AI applications in “edge computing” scenarios. The company's products include a variety of system-on-chip (SoC) with embedded software that supports AI computation, general computing, sensing, storage, security, wireless connectivity, and graphics processing.

At present, Ambiq's products have powered more than 270 million devices, and in 2024 alone, 42 million chips have been shipped, of which more than 40% support AI algorithm computation.

According to financial data disclosed by it, Ambiq Micro achieved revenue of $77 million in the past 12 months ending March 31, 2025. The company's current fund-raising is mainly used for product research and development, market expansion, and general operating purposes.

In the current context of the rapid development of the AI industry, demand for low-power, high-efficiency chips for edge computing has surged, making Ambiq Micro's technology route particularly critical. Compared to large model solutions that rely on the cloud, Ambiq's solutions are closer to terminal devices, such as smart wearables, medical monitoring, and industrial IoT scenarios, and have natural advantages in environments where power consumption is limited.

In AmbiQ's IPO, Bank of America Securities, UBS Investment Bank, Needham & Co. and Stifel are co-bookkeepers. It is expected to be priced and traded during the week of July 28, 2025.
