In connection with the offering, Ambiq also plans to provide the underwriters with a 30-day option to purchase up to an additional 510,000 shares. This option is intended to cover any over-allotments and would be exercised at the initial public offering price, minus applicable underwriting discounts and commissions.
Ambiq has submitted an application to list its common stock on the New York Stock Exchange. If approved, it will trade under the symbol AMBQ.
BofA Securities and UBS Investment Bank are serving as the joint lead book-running managers for the offering. Needham & Company and Stifel will also participate as joint book-running managers.
Ambiq says its mission involves supporting the expansion of intelligence—including artificial intelligence and other forms—across a wide range of environments by offering semiconductor solutions that prioritize low power usage. The company works with customers to make AI processing possible at the network edge, a setting where constraints around energy use tend to be particularly demanding.
Ambiq’s approach centers on a set of technological developments built on its patented and proprietary Sub-threshold Power Optimized Technology (SPOT). This platform is designed to significantly reduce power requirements when compared with more conventional semiconductor design methodologies.
To date, Ambiq’s solutions have been integrated into more than 270 million electronic devices, contributing to a broad range of use cases that require efficient on-device computing capabilities.
