Ambiq Micro Files for $85M IPO, Targets AI Edge Computing Market

Ambiq Micro Inc. is looking to raise as much as $85 million from an initial public offering.

The Austin-based manufacturer of ultra-low power semiconductors for artificial intelligence applications said it plans to market 3.4 million shares of its common stock at $22 to $25 each, according to a filing Monday with the U.S. Securities and Exchange Commission. If fully subscribed, Ambiq would raise from $74.8 million to $85 million.

It plans to trade under the ticker symbol AMBQ.

Ambiq said its move is driven by increasing adoption of AI across businesses and the need for low-power semiconductors.

"To fully realize AI’s potential, computation must move to the edge where data originates, enabling faster decisions, enhanced privacy, improved energy efficiency, and reduced cloud reliance," it said in its filing. "However, realizing this vision requires overcoming a fundamental challenge: power efficiency."

For the three months ended March 31, Ambiq reported a net loss of $8.3 million on revenue of $15.7 million. That was an improvement from a net loss of $9.4 million on revenue of $15.2 million a year earlier. For full-year 2024, its net loss was $39.7 million on revenue of $76.1 million. In 2023, its net loss was $50.3 million on revenue of $65.5 million.

The company was founded in 2010 and has offices in West Austin near the Riverplace neighborhood. It says its chips are used in more than 270 million devices, including most smartwatches and fitness bands. Most of its customers are in China, but the company said in its filing it plans to move to new markets "given geopolitical concerns" and "price sensitive environment."

One of Ambiq’s investors is Arm Holdings Plc, a British semiconductor company whose parent is Japanese investment group SoftBank Group.
