Ambiq Micro, a US-based designer of ultra-low power semiconductor solutions, completed its secondary listing on the Singapore Exchange (SGX) mainboard on July 30, 2026 [1, 2, 3]. The listing was done by way of introduction, with no new shares issued or capital raised in Singapore [1, 2, 3].

The company maintains its primary listing on the New York Stock Exchange (NYSE), where it went public in July 2025, raising US$96 million in its initial public offering [2, 4, 3]. Ambiq Micro's NYSE shares closed at US$57.26 on July 29, 2026, the day before its debut on SGX [1, 2, 3].

On the SGX debut, Ambiq shares opened at S$73.74 and closed nearly flat at S$73.80, with about 380 shares traded worth roughly S$30,000 [1, 3]. Pol de Win, Head of Global Sales and Origination at SGX Group, said, "Ambiq’s debut makes it the first sizeable global fabless semiconductor design company on SGX, giving investors access to two of the fastest-growing areas in technology, namely AI and semiconductors" [2]. He added that "as AI moves out of the data centre and onto everyday devices, a Singapore listing elevates Ambiq’s profile with Asian investors while supporting its R&D and regional market expansion" [3].

Ambiq Micro has a significant research and development (R&D) and engineering facility in Singapore, which was expanded in February 2026 [1, 2, 3]. Supported by the Singapore Economic Development Board, the company is undertaking a multi-year R&D program in the country [2, 4, 3]. Ambiq specializes in ultra-low power semiconductor technology for AI running on battery-powered edge devices such as wearables and smart infrastructure [1, 2, 3].

Fumihide Esaka, Ambiq Micro CEO, said, "Singapore has been a strategic part of Ambiq’s growth for many years" and described the dual listing as reflecting "the significance of our long-term commitment to Singapore and the broader Asia-Pacific region" [1]. He also noted, "So many companies claim to be global, but they are often US-centric. The secondary listing is a reflection of commitment to Singapore and the Asia-Pacific region" [4].

The secondary listing aligns Ambiq's capital markets presence with its operational footprint and growth strategy in Asia-Pacific [1, 4].
