And now it is my pleasure to turn the call over to Ambiq Micro, Inc.’s CEO, Fumihide Esaka.

Fumihide Esaka: Good morning, everyone, and thank you for joining us. 2025 was a strong year for Ambiq Micro, Inc., defined by disciplined execution and accelerating demand for edge AI across our end markets. Our performance reflects both share gains and market expansion as we enable AI on more devices across more markets and in a growing number of use cases. We are entering 2026 with strong momentum. Based on current demand indicators, we expect outsized top-line growth. We remain confident in our long-term opportunity as we partner with customers to advance their edge AI roadmaps and deliver sustained growth. Starting with Q4 performance, we delivered our highest net sales quarter of 2025, exceeding guidance.

End-user demand outpaced our customers’ expectations, resulting in incremental expedited orders late in the quarter. Three key factors behind the net sales increase from Q3 were, first, strong end demand for our customers’ products; second, broader adoption of Ambiq Micro, Inc. solutions within customer portfolios; and third, customers upgrading to Apollo 5 for more advanced edge AI functionalities. Turning to the full year, 2025 was a milestone year for Ambiq Micro, Inc. Edge AI adoption was a clear growth driver, and we estimate that more than 80% of the units we shipped were running AI algorithms. Net sales and non-GAAP gross profit increased in every quarter of the year, and we delivered our highest-ever gross profit for the year.

We expanded our customer base across multiple end markets, including securing a large wearable customer. At the same time, we continued to strengthen and diversify our design funnel, particularly in medical, industrial, and smart home and building markets. As these programs move into production over the next 18 to 24 months, we expect incremental growth and revenue diversification. We also expanded our product portfolio to support more advanced edge AI applications, launching Apollo 510 Lite, Apollo 510B, and Apollo 330. On the software side, we introduced the Helia AOT and Helia RT AI runtime powered by our new Helia Core AI kernel library.

Finally, we completed a successful IPO, demonstrating strong investor demand and confidence in our strategy and long-term opportunity. Our 2025 performance highlights the strengths of our SPOT platform in delivering ultra-low-power solutions and enabling edge AI across an increasingly diverse set of applications and end markets. Based on our customer conversations, we see several trends accelerating edge AI adoption in 2026, with SPOT enabling powerful new AI capabilities across an expanding range of industries. We expect to further grow market share while broadening the overall opportunity. First, customers are adding more sophisticated edge AI capabilities into their devices to differentiate their products and drive demand.

Second, wearables are evolving into true personal health platforms requiring more advanced on-device intelligence and ultra-low-power performance. This includes real-time health insights across multiple wellness indicators. Third, wearables are expanding into new high-value form factors such as rings and eyewear. This broadens the addressable market and increases demand for low-power, high-performance edge AI solutions. Looking ahead to 2026, we expect customers to launch new models with more advanced features across diverse form factors, including rings, display-less bands, and watches. We also expect a new scaled global customer to enter into mass production this year. Products launched in late 2025 are continuing to ramp in volume.

At the same time, we anticipate ongoing migration to Apollo 5 as customers look for greater performance and AI capability. As a result, we expect 2026 to be a year of strong growth for Ambiq Micro, Inc. While we are making impressive progress, we remain early in a large and expanding edge AI opportunity. To capture this opportunity, we are taking focused action to accelerate growth over the coming years. First, we are leveraging our existing Apollo family and derivatives to expand aggressively into high-value markets. Second, we are developing new products that enable more advanced edge AI capabilities and expand our reach. We are making solid progress on both fronts.

Starting with market expansion, edge AI is becoming more capable and complex across medical devices, smart homes, and industrial markets. In healthcare, customers are building smarter cardiac monitors, senior care devices, and hearing aids, all with enhanced AI capabilities. In industrial markets, AI-powered sensors are enabling predictive maintenance and asset monitoring, which helps reduce downtime and improve operational efficiency. In smart buildings, edge AI helps manage lighting, HVAC, security, and occupancy data to optimize energy use in real time. While these markets are growing, design cycles remain longer, particularly in regulated and industrial environments.

We are encouraged by our early traction and believe we are well positioned to expand our footprint as edge AI adoption scales across a broad range of end markets. Our integrated hardware and software platform is purpose-built for these transitions by combining AI-enabled processing, connectivity, and edge intelligence in a single ultra-low-power architecture optimized for power-constrained devices. Our recent partnership with RONS highlights this progress. Through the NavaSear brand, RONS is a leading provider of intelligent equipment operation maintenance solutions. By leveraging SPOT hardware and software, RONS will deploy large-scale, always-on battery-powered sensors. We expect this and similar engagements to increase diversity of our design funnel and unlock new and durable long-term growth in the industrial edge.

This is just one example of how SPOT is powering AI adoption across diverse end markets. We are building on this strong foundation with the ongoing expansion of our Helia AI software ecosystem. Helia will support more AI kernels, with performance improving over time. Paired with our AI development kits, Helia will help customers build ultra-efficient AI models for health analysis, speech interfaces, machine health monitoring, and more. Turning to our product roadmap, this morning we announced new technical details for Atomic. It is the first SPOT family built on a FinFET process with TSMC, enabling operation down to 300 millivolts, the lowest voltage in our company’s history.

This breakthrough pushes the boundary of ultra-low power while enabling significantly more sophisticated AI capabilities. This combination is essential for the next generation of battery-powered edge AI devices. Atomic is purpose-built for AI workloads that benefit from parallel processing rather than raw clock speed. With its integrated NPU, GPU, and embedded memory, we believe it will power a new class of intelligent devices, including advanced wearables, AR glasses, and smart cameras. At the same time, we see significant opportunity to extend our reach into new markets with Apollo derivatives that support smaller form factors and core edge AI capabilities. Reflecting stronger customer demand, we are accelerating development of both Atomic and Apollo product families.

Instead of a three-year step-by-step plan, we now plan to start development of Apollo 340 and Atomic 120 this year, along with ongoing work on Atomic 110. Apollo 340 is designed as a highly scalable platform to expand into new high-opportunity segments. It combines Ambiq Micro, Inc.’s energy efficiency with an attractive price point, compact form factor, and comprehensive developer support and reference designs. This will make it well suited for distribution channels, ecosystem partners, and reference designs, multiplying sales leverage and accelerating delivery of on-device AI to the mass market.

Turning to Atomic, the first SoC designed from the ground up for advanced AI, Atomic 110 will enable personal devices with smaller batteries to achieve longer battery life while supporting richer features such as natural-language voice interfaces and on-demand health analysis, unlocking new possibilities for personal life-logging devices. In industrial markets, Atomic will support more complex AI models for local, cost-effective predictive maintenance. In medical applications, it will enable more real-time, always-on, private metrics in smaller form factors. Atomic 120 will introduce capabilities tailored for smart cameras and next-generation smart eyewear, which is one of the fastest-growing categories in wearables. In summary, 2025 was a year of strong performance and focused execution for Ambiq Micro, Inc.

We believe in 2026 we are well positioned for significant top-line growth, supported by solid customer demand and accelerated product momentum. At the same time, we are intentionally increasing investment across R&D, software, and go-to-market initiatives to capture an even larger share of the expanding edge AI opportunity. Our ultra-low-power SPOT platform, combined with the strategic actions we are taking, is laying the foundation for sustained long-term growth. With that, I will turn the call over to Jeff to review the financials.

Jeffrey Winzeler: Thank you, Fumi, and good morning, everyone. Our 2025 performance reflects the benefits of our strategic repositioning, which strengthened the quality of our revenue base and aligned the company with long-term growth opportunities. At the end of 2024, we took deliberate steps to prioritize customers who view our ultra-low-power technology as a critical enabler of edge AI, while reducing exposure to efficiency-focused, feature-neutral customers primarily in Mainland China. As a result, we delivered sequential sales and non-GAAP gross profit improvement in every quarter of the year. Our full-year results reflect stronger margins and increased gross profit dollars by 32.1% on 4.7% lower net sales, achieving our highest-ever annual gross profit.

These results validate our strategic repositioning, and with the strong momentum in the business, we believe we are well positioned to deliver sustainable growth over the coming years. Now turning to our fourth quarter results, we delivered the highest net sales quarter of 2025 with results ahead of our guidance on accelerating demand trends. Net sales of $20.7 million increased 2% year over year. Non-GAAP gross profit increased 75.5% to $9.4 million, while non-GAAP gross margin expanded almost 20 percentage points to 45.5%. This performance reflects the impact of the strategic repositioning I just described, with 8.6% of net sales driven by customers in Mainland China, down from 50% in 2024.

Sequentially, net sales increased 14.2%, driven by strong underlying demand. Non-GAAP gross profit dollars increased 15.9%, with non-GAAP gross margin expanding 70 basis points. The improvement was driven by a more favorable product mix, reflecting higher sales to customers deploying multiple edge AI capabilities on our SPOT platform. Turning to operating expense, non-GAAP R&D expense was $9.3 million, up 33% year over year and 34% sequentially. This reflects additional investment that began in the fourth quarter to support our product development for both the Atomic and Apollo families. Non-GAAP SG&A expenses were $7.3 million, up 19.7% year over year, largely due to public company costs.

Sequentially, SG&A increased 17.4%, driven by strategic investments in sales and marketing as well as higher incentive compensation reflecting stronger net sales performance in the quarter. Other income was $1.3 million, up $1.1 million year over year due to interest income earned on IPO proceeds. Fourth quarter non-GAAP net loss attributable to common stockholders was $5.9 million, a $1.7 million improvement year over year and $1.9 million lower sequentially. Non-GAAP net loss per share attributable to common stockholders was $0.32. We ended the quarter with no debt and $140.3 million in cash and cash equivalents, reflecting the proceeds from our IPO. And in 2026, we completed a successful follow-on offering that generated an additional $76.8 million.

Our strengthened cash position provides flexibility to fund growth initiatives and support our strategic priorities. Now turning to our outlook, for 2026 we expect the following: net sales to be in the range of $21 million to $22 million, reflecting the trends Fumi covered earlier; non-GAAP gross margin between 44% and 45%, reflecting the ramp of the Apollo 5 family. We expect to see improved yield and a better cost structure as this product family scales throughout the year. Non-GAAP operating expense of $18.0 million to $18.5 million, reflecting increased investment to support our strategic growth priorities, including approximately $1.7 million related to IP purchases in the quarter.

Non-GAAP loss per share of $0.39 to $0.33, based on weighted average share count of 20.38 million shares outstanding. As you update your full-year models, please keep the following in mind. We are encouraged by the demand inflection we saw in 2025. We see a clear path to strong net sales growth in 2026 driven by new model launches, ramping of a scaled global customer, higher volumes from recent customer introductions, and continued adoption of Apollo 5. We remain focused on driving continued yield improvements across the portfolio while recognizing that gross margin may be affected by broader industry cost dynamics and supply chain pressures. We expect non-GAAP operating expense will be approximately $30 million higher than 2025.

This higher spending is tied to the accelerated development of both Atomic and Apollo product families, reflecting strong customer demand. The increased OpEx includes growing Ambiq Micro, Inc. engineering headcount, utilizing contract engineering to provide flex in our model for both upside and downside flexibility, and $7 million to $10 million of IP purchases necessary for product development. Given the timing of IP purchases will be project-driven, do not expect operating expenses to be linear in 2026. In summary, our 2025 results reflect the strength of our competitive position, disciplined execution, and favorable secular tailwinds.

Apollo is now powering multiple generations of products in production, and our expanding portfolio of derivatives is supporting upgrade cycles and broadening our reach across customers and end markets. At the same time, we are investing to enable higher-performance edge AI applications and expand our long-term revenue opportunity. With Apollo driving growth and margin expansion today, and Atomic positioned to contribute meaningfully beginning in 2028, we believe we have multiple growth drivers to support sustainable growth over time. With that, I will turn the call back to Fumi before we open the line for Q&A.

Fumihide Esaka: The opportunity ahead for Ambiq Micro, Inc. is large and growing quickly. We expect to deliver meaningful sales growth in 2026, and we are just getting started. As AI moves beyond the cloud and into everyday devices, our technology is helping lead this change. With SPOT’s industry-leading power efficiency, we enable intelligent devices that are mobile, secure, and personal. We bring powerful AI directly to where data is created and decisions are made. We believe this shift to true edge intelligence is a defining moment for our industry. We are excited about the role Ambiq Micro, Inc. will play in shaping this future. Thank you for your continued confidence and support. With that, I will open the call to questions.

Operator, please go ahead.

Operator: Thank you. The floor is now open for questions. If you have dialed in and would like to ask a question, please press star one. If you are called upon to ask a question and are listening via loudspeaker on your device, please pick up your handset and ensure that your phone is not on mute when asking your question. Again, it is star one to join the queue. Your first question comes from the line of Quinn Bolton of Needham & Company. Your line is open.

Quinn Bolton: Hey, guys. Congratulations on a nice finish to 2025 and a strong outlook for 2026. I guess, let me ask: Fumi or Jeff, you have mentioned several times your strong outlook for 2026. I am wondering if there is any sort of guidance you can provide around that. I mean, certainly, you could be on pace to generate north of $90 million of revenue, maybe even approaching $100 million. And a related follow-up: historically, you have seen revenue peak in June, just reflecting seasonality of some of your wearable customers. In 2025, you saw sequential growth throughout the year. What kind of revenue pattern quarter to quarter would you expect?

Do you think Q2 is the peak, or could it be a more linear ramp through the year? And then I have a follow-up.

Fumihide Esaka: Hi, Quinn. Thanks for the great comment. Like I said in the script, Q4, definitely, we are seeing as an inflection point. Customer forecasts are coming in extremely strong, and the trend will continue in 2026. Again, we see Q1, Q2, Q3 to be extremely strong, and Q4, I think we are still a little bit at a far distance, and typically seasonality will fix in Q4. But we clearly see a path to more than $100 million at this point, and we are very confident that we can achieve more than what we originally forecasted. Does that answer your question?

Quinn Bolton: That is great. And then a question if Scott is there. You announced that 12-nanometer SPOT technology gets down to operating voltage as low as 300 millivolts. If I looked at a more standard low-voltage process at TSMC for 12 nanometer, does that get down to 400, 500 millivolts? How much lower at 300 millivolts would the SPOT process be than the standard foundry offering at TSMC? Just trying to get a sense of the power advantage you bring with the 12-nanometer SPOT technology. Thank you.

Scott Hanson: Process nodes across foundries is going to be on the order of 700 millivolts, so 0.7 volts. We are running at a fraction of that operating voltage. If you are running at, let us say nominally, to make it easy math, 350 millivolts against a 700 millivolt competitor, that is going to give you a fourfold energy advantage. Of course, things are a little more complex than that. On the one hand, I have always said that a good portion of the SPOT advantage comes from all the stuff we do other than voltage scaling: the way we build our clock trees and our bus fabrics and our memories and everything else.

You have the potential to go more than 4x if you layer all that innovation in. We feel really good about what 12 nanometer is looking like and are excited about some of the early measurements that we are seeing in-house.

Quinn Bolton: That is great. Thank you.

Operator: Your next question comes from the line of Tore Svanberg of Stifel. Your line is open.

Tore Svanberg: Yes. Thank you and congratulations on the strong results. Fumi, could you talk a little bit more about some of the applications or end markets that are going to be driving the strong growth in calendar 2026? I mean, obviously, wearables have been a big part of the business, but you are now getting into industrial. Any more color on the types of applications that will be driving the growth would be very helpful.

Fumihide Esaka: Thanks. We are seeing strengths in every product line and end market. First, let me tell you that Apollo 3 family, 4 family, and Apollo 5 family are seeing very strong demand to enable edge AI. And, yes, major increase is still coming from wearable customers, but 25% of the funnel is now non-wearables and medical and so on. We do expect more than the original percentage of the share as non-wearables in 2026. The growth is phenomenal. You would expect our traditional industrial leaders, but some other medical and industrial applications will be contributing to our 2026 revenue.

Tore Svanberg: Very good. And as my follow-up, you talked about some volatility in the OpEx for the year. I was just hoping you could give us a little bit more feel for whether it is going to be first-half weighted or second-half weighted, because I think you did say it is not going to be linear. Any more color on first half versus second half would be very helpful. Thank you.

Jeffrey Winzeler: Sure. As we think about OpEx for 2026, as you know and as we said on the call, we are going to invest roughly a $30 million increase in our OpEx year over year. The way that is going to break out is there are three major components that really drive that increased spending. The first is Ambiq Micro, Inc. headcount. We are going to hire more engineering in both hardware and software and continue to grow our internal capabilities. That spending will be somewhat linear as we add more people to the company. The second place that we are going to spend that money is in contract engineering.

This is important because it gives us scale both on the upside and the downside. It gives us a more variable cost structure. For that contract engineering, it will be very much project-based. As we think about the products that we are going to tape out in 2026, you would expect to see very high periods of engineering, probably more in the Q2, Q3 timeframe, where we will utilize that project engineering. The last place that we will spend a significant amount of money is in our IP acquisition. These IPs are necessary for us to build new products, and that is very project-based.

It is not a linear spend, and given it is to support products that we are going to tape out in the second half of the year, I would expect the majority of that spending to take place in the Q2, Q3 timeframe.

Tore Svanberg: Very helpful. Congrats again.

Operator: Thank you. And again, if you have a question, please press star one on your telephone keypad to join the queue. Your next question comes from the line of Vivek Arya of Bank of America. Your line is open.

Vivek Arya: In terms of elevated component pricing, are you seeing any impact on demand due to that? Are you relatively insulated from any pricing pressure from your customers as they want to preserve their margins? And how should we think about the gross margin trajectory through the year, given the introduction of a lot more new, higher-complexity Apollo SKUs with your customers and more design wins? Should we expect that to accrete significantly or remain around this 45% zip code?

Jeffrey Winzeler: When we think about margins, first of all, we are very happy with the margin accomplishments that we made in 2025. We increased our gross profit dollars by over 30% year over year, and we increased our gross margin year over year, going to 45% for total 2025. When we think about the margin equation going forward, there are two components. The first is the ASP side of the equation, and there we continue to focus on opportunities where we can maximize our value. We are very much looking for high-revenue opportunities where we get paid the most on a per-unit basis for our product.

On the cost side of the equation, we are very focused on things that we can control, which are yield across our product portfolios. That said, our efforts may be tempered by some of the dynamics that are happening in the industry. The increasing cost of being a fabless semiconductor company exposes us to higher pricing of our capacity, probably more in the back half of the year. That aspect of it we are monitoring very closely, and that could put pressure on our ability to grow margins year over year.

Vivek Arya: Okay. Thank you. And then in terms of this new customer you have got in 2025, any idea in terms of the timing of that ramp, when it becomes sizable? Should we expect that socket to be similar size to your other wearable customers, or will it remain a little bit smaller?

Fumihide Esaka: You mean 2026, right? That new customer is starting to ramp starting Q1 with very, very strong growth quarter after quarter, and we expect that 2027 will be even bigger. We are very excited to have that new customer being a big family.

Operator: Thank you. And we have a follow-up question from Quinn Bolton of Needham & Company. Your line is open.

Quinn Bolton: I know you do not give us a split quarter to quarter on Apollo 3, 4 versus 5, but it does sound like you are seeing broader adoption of Apollo 5. Could you give us any rough percentage of revenue that was Apollo 5 exiting 2025, and what percent of revenue it could reach in 2026? Is it a pretty significant mix shift up to Apollo 5? Any comments would be helpful.

Fumihide Esaka: Apollo 5 is definitely increasing, but again, the denominator—you know that our total revenue is growing faster than expected—and Apollo 3 is really enabling one of the big customers. Apollo 4 is enabling one of the newer customers that joined in 2025, and Apollo 5 is across all the customers. All of them are growing, and for Apollo 5, I have to say that the quantity itself is growing fast. If you ask about the percentage, we do not give out too much of that percentage, but the percentage is slowly growing, while the absolute quantity is growing fast.

Quinn Bolton: Okay. Got it. Thank you.

Operator: With no further questions, that concludes our Q&A session. This also concludes today’s conference call. We thank you for your participation. You may now disconnect.
