Ambiq Micro, the Austin-based semiconductor designer, commenced trading on the Singapore Exchange (SGX) on Thursday (July 30), securing a dual-market foothold a year after its New York IPO as it expands its commercial presence across South-East Asia.
The Texas-headquartered group joined the SGX mainboard under the ticker AMQ. Its primary listing will remain on the New York Stock Exchange under the ticker AMBQ.
Executed by way of introduction, the secondary listing involved no new capital raise or share issuance. The transaction is aimed instead at expanding investor access across Asia, with shares trading in Singapore dollars in standard board lots of 10.
The public listing builds on a state-backed relationship dating to 2018, when EDB Investments (EDBI), then the investment arm of the Singapore Economic Development Board, led Ambiq’s $28 Mn Series E funding round.
Ambiq established a Centre of Excellence in Singapore in 2020, before opening a technology design centre in the city-state in 2022 focussed on integrated-circuit design, verification and hardware validation. Earlier this year, it expanded that footprint through a multi-year research and development programme supported by the EDB to advance its low-power semiconductor technology and scale its local engineering and commercial teams.
Ambiq designs chips and outsources wafer fabrication. It specialises in ultra-low-power microcontrollers and systems-on-chip (SoCs) for energy-constrained hardware, including wearables, medical electronics and smart-infrastructure sensors.
Its foundational Subthreshold Power Optimized Technology (SPOT) platform is designed to reduce energy consumption while preserving the processing capability required for edge AI, where some artificial-intelligence workloads move from remote data centres onto local devices.
Ambiq says its technology has powered more than 300 Mn devices globally. More than 80% of its first-quarter shipments were running AI algorithms.
Like many high-growth hardware companies, the group remains loss-making. First-quarter revenue for 2026 jumped 59.3% year on year to $25.1 Mn, but its net loss widened to $10.2 Mn from $8.3 Mn in the prior-year period. Research and development spending rose 47.7% to $12.8 Mn as the company increased spending on intellectual property, technology, contractors and employees.
For SGX, Ambiq adds a different kind of semiconductor company to a market historically represented by businesses such as Chartered Semiconductor Manufacturing, which operated foundries, and STATS ChipPAC, which specialised in assembly, packaging and testing.
Ambiq flips this traditional dynamic. By anchoring its high-value research and design operations in Singapore after listing in New York, the company gives SGX its first sizeable global fabless semiconductor design company. The debut effectively aligns Ambiq’s capital-market profile with its regional technology footprint.
