Ambiq Micro, a pioneer in ultra-low power semiconductor technology, has officially filed for an initial public offering on the New York Stock Exchange under the ticker symbol 'AMBQ', joining the wave of AI-focused chip designers capitalizing on the industry's explosive growth.
Founded in 2010 and headquartered in Austin, Texas, Ambiq reported a 16.1% increase in net sales to $76.1 million for 2024, while simultaneously reducing its net loss to $39.7 million from $50.3 million in the previous year. The company plans to use the IPO proceeds, which could reach up to $75 million according to SEC filings, for general corporate purposes including working capital, sales and marketing activities, and product development.
Ambiq's competitive edge lies in its proprietary Subthreshold Power Optimized Technology (SPOT) platform, which dramatically reduces power consumption in semiconductor chips. This technology enables AI processing at the edge - directly on devices rather than in cloud data centers - while extending battery life from days to months or even years. The company's solutions include systems-on-chip (SoCs) and software that enable on-chip AI processing, general computing, sensing, security, and wireless connectivity for battery-powered devices.
The company has already shipped over 270 million devices as of early 2025, with more than 40% of its 42 million units shipped in 2024 running AI algorithms. Ambiq's ultra-low power chips are particularly valuable for wearables, IoT devices, and other applications where energy efficiency is critical, with customers including major tech companies like Google and Huawei.
Ambiq's IPO comes at a strategic time as the global AI chip market experiences unprecedented growth. Industry analysts project the market to reach $166.9 billion in 2025, growing at a CAGR of over 20% through 2029. The edge AI segment, where Ambiq specializes, is particularly promising, with the market expected to grow from $20.78 billion in 2024 to $66.47 billion by 2030.
While Ambiq faces competition from semiconductor giants and is exposed to customer concentration risk by relying on a few large players, its focus on ultra-low power AI chips positions it well in the rapidly expanding market for energy-efficient edge computing solutions. BofA Securities and UBS are serving as the lead underwriters for the offering.
