Founded in 2010 by University of Michigan researchers Scott Hanson, David Blaauw, and Dennis Sylvester, the company was originally incorporated as Cubiq Microchip, Inc. and changed its name to Ambiq Micro, Inc. in October 2012. Ambiq is headquartered at 6500 River Place Boulevard in Austin, Texas, with additional international operations and teams in locations including Shanghai and Shenzhen, China, Hsinchu, Taiwan, and Singapore. Fumihide “Humi” Esaka has served as chief executive officer since 2015, while co-founder Scott Hanson serves as chief technology officer.
The company’s core intellectual property is its patented Subthreshold Power Optimized Technology, or SPOT®, platform. The technology is intended to enable extremely low operating power while maintaining useful processing performance, making it suitable for devices where battery size, operating lifetime, heat, and charging frequency are important design constraints. Ambiq’s products include ultra-low-power real-time clocks, microcontrollers, wireless and sensor-oriented integrated circuits, and Apollo system-on-chip products. Apollo platforms combine embedded processors and memory with capabilities designed for edge artificial intelligence, allowing selected AI workloads to run locally on a device rather than requiring constant connectivity to a cloud service. Ambiq has also introduced Atomiq, a platform aimed at more advanced AI acceleration and memory-related innovation.
Ambiq primarily operates as a fabless semiconductor company. This means its business model emphasizes chip architecture, circuit design, software, intellectual property, validation, customer support, and product marketing, while wafer fabrication and much of the assembly and testing are outsourced to specialized manufacturing partners. Consequently, its bill of materials is centered on semiconductor wafers, packaging, testing, embedded memory, engineering resources, and third-party manufacturing services rather than owning and operating large fabrication facilities. This model can reduce fixed manufacturing investment, but it exposes the company to foundry capacity, supply-chain availability, packaging costs, inventory requirements, and semiconductor-cycle volatility.
Its target customers and applications include smartwatches and other wearables, healthcare and fitness devices, intelligent cards, wireless sensor networks, industrial equipment, smart-home products, and broader Internet of Things deployments. Ambiq supports customers through technical assistance and sales representatives. The company reported approximately 202 employees in the supplied company information, placing it in the 201-500 employee category, although employee counts can vary by reporting date and methodology.
The supplied financial snapshot identifies Ambiq as a publicly traded company on the New York Stock Exchange under AMBQ, with an IPO date of July 30, 2025. It reports trailing twelve-month revenue per share of approximately $4.01, negative net income per share of approximately $1.88, and a gross margin of about 42.3%. The same snapshot shows substantial research and development investment, with R&D expense equal to roughly 52.1% of revenue, reflecting the high engineering intensity of semiconductor and edge-AI development. Selling, general, and administrative expense was approximately 42.1% of revenue. Trailing twelve-month profitability metrics were negative, including a net profit margin of approximately negative 46.9% and negative free cash flow, indicating that the company’s financial profile reflects ongoing investment and operating losses rather than mature-scale profitability. Ambiq’s long-term opportunity is tied to the expansion of edge AI and connected devices, while its key challenges include competition, customer adoption cycles, manufacturing dependence, pricing pressure, product execution, and the need to convert technology advantages into sustainable revenue and cash flow.
YoYYoY means Year-over-Year. It compares the latest annual value with the previous annual value to show long-term trend strength.
QoQQoQ means Quarter-over-Quarter. It compares the latest quarter with the immediately previous quarter to show short-term momentum changes.
RevenueThe total money that came through the front door from selling things, before paying a single bill. Think of it as the grand total of every credit card swipe from customers. (YoY compares this year to last year's performance, while QoQ compares the current three months to the previous three).

Gross MarginThe basic markup. If they sell a $100 pair of sneakers, this percentage tells you how much of that price tag is profit right after paying for the rubber and shoelaces, but before paying for things like store rent or TV commercials.

Free Cash FlowThe holy grail of corporate cash. It's the spendable, physical money left over after the business pays for its daily operations AND buys the big, expensive upgrades (like new factories or servers) it needs to survive. This is the 'free' money they can use to pay dividends or buy back stock.

Operator: Good morning, and welcome to the Ambiq Micro Second Quarter 2026 Earnings Conference Call. As a reminder, this conference call is being recorded. [Operator Instructions] I'd now like to turn the call over to Ms. Charlene Wan, Ambiq's Vice President of Corporate Marketing and Investor Relations. Charlene, please go ahead.
Charlene Wan: On today's call, Ambiq's CEO, Fumihide Esaka, will provide an overview of the company's performance and strategy. CFO, Jeffrey Winzeler, will then discuss the quarter's financial results and outlook. Following their remarks, Scott Hanson, Ambiq's Founder and CTO, will join Fumi and Jeff for Q&A. Our earnings release is available on the Investor Relations page of our website at www.ambiq.com. We have also posted our earnings presentation on the Investor Relations section of our website. Before I turn the call over to Fumi, I'd like to remind our listeners that during the course of this conference call, management will discuss non-GAAP financial measures. Reconciliations of these non-GAAP measures to their most directly comparable GAAP measures are included in our earnings release available on the company's Investor Relations website. In addition, today's call will contain forward-looking statements representing management's beliefs and assumptions only as of the date made. Our most recent quarterly report on Form 10-Q and other filings with the SEC provide more information on specific risks that may cause the actual results to differ materially from current expectations. And now it's my pleasure to turn the call over to Ambiq's CEO, Fumi Esaka.
Fumihide Esaka: Good morning, everyone, and thank you for joining us. Since the start of the year, we've seen a step change in demand for Edge AI, which supports our strong performance and further increases our conviction in the magnitude and durability of the long-term opportunity. Across end markets, companies are embedding more sophisticated AI into a broader range of devices and end-user demand is far exceeding our expectations and those of our customers. With our full stack ultra-low power solutions, Ambiq's defining technologies are not only enabling but further accelerating this next chapter in AI. This positions us to continue outpacing the broader market as we take share and expand our addressable opportunity. This momentum is reflected in our second quarter results. Net sales were ahead of guidance, growing approximately 90% over last year and marking our fifth consecutive quarter of sequential growth. We also raised approximately $168 million in net proceeds through a successful follow-on offering. The strong investor interest serves as a proof point of confidence in our ability to capitalize on the meaningful opportunity ahead. Turning to the details of the quarter. Demand accelerated across customers, end markets and products. Customer programs grew on healthy end-user demand, positive response to customers' recent launches and continued ramping of our …
