We own and operate wafer fabrication facilities (“fabs”) in Icheon and Cheongju, Korea and Wuxi and Dalian, China. We also own and operate assembly and testing facilities for back-end processing of our products in Icheon and Cheongju, Korea and Chongqing, China. As part of our efforts to reduce unit manufacturing costs, improve manufacturing yields and enhance our profitability, we periodically phase out the operations of our older fabs or upgrade them to implement more advanced processing technologies. In addition to regular maintenance and enhancement of existing fabs, in October 2025, we opened the cleanroom of a new extension fab called “M15X” in Cheongju, which we plan to utilize to further increase our production capacity of next-generation DRAMs such as HBM. We began wafer input at the M15X in the first quarter of 2026 and expect to gradually ramp up our production volume. As part of our efforts to ensure our long-term competitiveness, we have also announced initiatives to construct an integrated industrial complex in Yongin, Korea for our next generation of fabs and research and development facilities. We began construction of our first fab at the Yongin complex in February 2025 with the phase 1 cleanroom of the first fab expected to open in the first quarter of 2027. We are currently constructing an advanced packaging plant called “P&T7” in Cheongju and expect to complete construction by the end of 2027. In December 2024, we also announced plans to build an advanced packaging plant in Indiana, United States, and expect to commence operations in the second half of 2028. In order to maintain our technological leadership, as well as to access new markets for our products, we engage in strategic initiatives, including making investments and acquisitions, from time to time. In October 2020, we agreed to acquire the NAND flash memory and storage business of Intel Corporation (“Intel”) (the “Intel NAND Business Acquisition”), including the NAND flash memory manufacturing facility in Dalian, China, NAND flash memory and SSD-related intellectual property and research and development personnel. As consideration for the Intel NAND Business Acquisition, we paid US$6.6 billion in December 2021 and US$2.2 billion in March 2025. We created a subsidiary in the United States to operate the acquired business under the brand name “Solidigm.” We also selectively acquire minority equity positions in other industry players to further strengthen our business relationships and acquire complementary businesses that we believe can further strengthen our leading position in the industry. Our principal executive offices are located in Korea.

About Ambiq Micro

Our mission is to enable intelligence (artificial intelligence (AI) and beyond) everywhere by delivering the lowest power semiconductor solutions. We are a pioneer and leading provider of ultra-low power semiconductor solutions designed to address the significant power consumption challenges of general purpose and AI compute – especially at the edge. Our customers rely on Ambiq to deliver AI compute closer to end users (edge environments) where power consumption challenges are the most severe. Our leading position is built upon our hardware and software innovations that deliver two to five times lower power consumption than traditional semiconductor designs. Our products power over 270 million devices today. We shipped more than 42 million units in 2024, and we estimate that over 40% of them ran AI algorithms. 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. 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. AI is perhaps the most disruptive and revolutionary technology trend of recent history, estimated to represent $23 trillion of global annual spend by 2040, according to McKinsey. AI use cases continue to permeate our lives and improve our daily productivity by enabling us to interact with devices via voice and gestures, unlock our homes with facial recognition, track health accurately and intelligently, and hold clear calls amidst loud background noise. To date, a majority of AI compute has been deployed in data centers due to its large physical scale and the need for wall plug energy, as AI compute requires enormous and steady energy resources. At the edge, however, power limitations have been especially acute due to small device size and limited battery life. We believe this greatly constrains the potential of AI to improve our daily, on-the-go lives. Enabling AI at the edge – where the action takes place – with vastly improved power efficiency will allow faster real-time decision-making due to data proximity, greater data privacy, higher energy efficiency from reduced network usage, and less dependence on constant costly connections to the cloud. We believe new AI use cases will only be possible if edge devices are much more power efficient. Our proprietary Sub-threshold Power Optimized Technology (SPOT) platform is designed to fundamentally and cost-effectively reduce power consumption of battery- and wireline-powered devices alike. Depending on the application, devices incorporating SPOT demonstrate a two to five times reduction in power consumption compared to conventional integrated circuit designs. SPOT is a ground-breaking approach at the chip design level that incorporates sub- and near-threshold hardware without using expensive manufacturing processes. We provide a full-stack solution encompassing tightly integrated hardware and software. Our solutions include a diverse family of systems-on-chip (SoCs) and the software required to enable on-chip AI processing, general compute, sensing, security, storage, wireless connectivity, and advanced graphics. Our SoC solutions deliver compute at a very small fraction of the power consumed by our competitors’ products. Our ultra-low power SoCs serve a wide range of markets requiring on-device and real-time AI, including smartwatches and fitness trackers, augmented and virtual reality (AR/VR) glasses, smart rings, digital health monitors, security systems and access control, livestock tracking, crop monitoring, and factory automation. These devices increasingly offer on-chip AI-powered features such as speech recognition, domain-specific language models, image and video processing, and sensing, further straining power consumption, which our solutions are positioned to address. As global demand for our SoC solutions accelerates, our sales and marketing efforts are increasingly focused on our end customers in target geographies such as the United States, Europe, and Asia (ex-MainlandChina). We were incorporated in Delaware on January 20, 2010 under the name Cubiq Microchip, Inc., and in October 2012, changed our name to Ambiq Micro, Inc. Our principal executive offices are located in Austin, Texas.
