Ambiq Micro files for IPO, set to trade under AMBQ ticker

Semiconductor company Ambiq Micro filed on Thursday for its upcoming initial public offering, and said it will trade under the “AMBQ” ticker on the New York Stock Exchange.

The Austin, TX.-based company generated $15.7M in revenue in the first-quarter of 2025, up from $15.2M in the year-ago period, the company said in its S-1 filing with the Securities and Exchange Commission. Revenue for the 2024 fiscal year was $76.1M, up from $65.5M in fiscal 2023.

Ambiq saw a $14.8M net sales increase in customers from the U.S., Europe and Asia (excluding Mainland China), a 94% increase from the year-ago period. Net sales from the aforementioned group grew to $38.1M in 2024, up 70% year-over-year. The company said it intends to focus its business outside of Mainland China.

Products from the company are inside more than 270M devices (many of them at the edge), including shipping more than 42M in 2024.

“We seek to drive growth in AI adoption at the edge in the personal devices, medical/healthcare, industrial edge, and smart home and building markets and continue to set new standards in edge AI performance and power efficiency,” the company said in the filing. “Over time, we expect to integrate our ultra-low power technology into additional chip products that benefit from greater power efficiency, including high-performance compute applications such as AI data centers and automotive.”

Ambiq competes with a number of large microcontroller companies, including Texas Instruments (NASDAQ:TXN), Microchip (MCHP), STMicroelectronics (NYSE:STM), Silicon Laboratories (SLAB), NXP Semiconductors (NASDAQ:NXPI), Renesas and Infineon (OTCQX:IFNNY). It also said it competes with connectivity companies such as Synaptics (SYNA) and other larger semiconductor companies, such as Qualcomm (QCOM).

The IPO is being led by BofA (BAC) Securities, and other investment banks on the offering include UBS (UBS), Needham and Stifel.
