Ambiq Micro, which designs ultra-low power chips for AI computing and other applications, filed on Thursday with the SEC to raise up to $75 million in an initial public offering.
Ambiq Micro provides ultra-low power semiconductor solutions designed to address the significant power consumption challenges of general purpose and AI compute, especially at the edge. The company's proprietary Sub-threshold Power Optimized Technology (SPOT) platform is a proprietary ultra-low power chip design platform, consisting of a set of chip design techniques that allow standard transistors to operate in an ultra-low power mode called "sub-threshold" and "near-threshold." Ambiq's solutions include a diverse family of systems-on-chip (SoCs) and the software required to enable on-chip AI processing, general compute, sensing, security, storage, wireless connectivity, and advanced graphics. The company's products power over 270 million devices today. It shipped more than 42 million units in 2024, and it estimates that over 40% of them ran AI algorithms.
The Austin, TX-based company was founded in 2010 and booked $77 million in sales for the 12 months ended March 31, 2025. It plans to list on the NYSE under the symbol AMBQ. BofA Securities, UBS Investment Bank, Needham & Co., and Stifel are the joint bookrunners on the deal. No pricing terms were disclosed.
