Access earnings results, analyst expectations, report, slides, earnings call, and transcript.
Overview
The earnings call presented mixed signals: a strategic shift away from China led to reduced sales there, but overall revenue increased sequentially. Gross profit improved YoY, but operating expenses rose sequentially. The Q&A revealed optimism about edge AI growth and a stable gross margin outlook, yet management's vague responses on key metrics and timelines dampened sentiment. Despite some positive financial metrics, the lack of clear guidance and ongoing losses suggest a neutral stock price movement over the next two weeks.
Key Financial Performance
Revenue $17.9 million in Q2 2025, compared to $15.7 million in Q1 2025 and $20.3 million in Q2 2024. The sequential increase was driven by increased customer demand and favorable product mix. The year-over-year decrease was due to the strategic decision to diversify revenue toward higher-value opportunities outside of China.
Net Sales to Mainland China 11.5% in Q2 2025 compared to 42% in Q2 2024. This significant reduction reflects the company's strategic shift to prioritize geographies outside of China.
Non-GAAP Gross Profit $7.6 million or 42.7% of revenue in Q2 2025, compared to $7.4 million or 47.1% in Q1 2025 and $6.7 million or 32.9% in Q2 2024. The year-over-year increase was due to a more favorable product and customer mix.
Non-GAAP Operating Expenses $13.8 million in Q2 2025, compared to $13.1 million in Q1 2025 and $14.4 million in Q2 2024. The slight year-over-year decrease reflects controlled spending while focusing on strategic initiatives.

Geographic diversification: Ambiq has significantly reduced its sales reliance on Mainland China, with sales to the region dropping from 42% in Q2 2024 to 11.5% in Q2 2025. The company is prioritizing other geographies as demand for edge AI grows globally.
New customer acquisition: Ambiq has secured new customers, including Whoop, which uses Apollo SoCs in its fitness trackers. The Whoop 5.0 and Whoop energy products offer advanced health monitoring with extended battery life.
Revenue growth: Q2 2025 revenue increased to $17.9 million from $15.7 million in Q1 2025, driven by increased customer demand and favorable product mix.

Risk or Challenges
Revenue Diversification: The company has significantly reduced its reliance on sales to Mainland China, which now accounts for only 11.5% of net sales compared to 42% in the same quarter of 2024. While this diversification reduces geopolitical risks, it also presents challenges in penetrating new markets and geographies, which may take time and resources to establish.
Profitability Challenges: Despite revenue growth, the company reported a net loss of $8.5 million for the second quarter of 2025. Non-GAAP gross profit margin also declined sequentially from 47.1% to 42.7%, indicating potential challenges in maintaining profitability.
R&D and Operating Expenses: The company is scaling its R&D and go-to-market capabilities, leading to increased operating expenses. Non-GAAP operating expenses rose to $13.8 million in Q2 2025, up from $13.1 million in the prior quarter. This could strain financial resources if revenue growth does not keep pace.
Market Competition: The company operates in a highly competitive semiconductor market, particularly in the edge AI space. The need to continuously innovate and launch new products like the Apollo and Atomic families adds pressure to maintain technological leadership.
Strategic Execution Risks: The company’s ambitious plans to expand into new markets, develop new product lines, and establish an IP licensing model for its SPOT platform involve significant execution risks. Delays or failures in these initiatives could impact long-term growth.
Economic and Geopolitical Risks: The shift away from Mainland China sales reduces exposure to geopolitical risks but also limits access to a large market. Additionally, global economic uncertainties could impact customer demand and supply chain stability.

Product development and innovation: Ambiq is scaling its R&D and go-to-market capabilities to capture edge AI opportunities. The company plans to expand its Apollo family and introduce the new Atomic product line, targeting high-performance and low-power AI applications. The Atomic family will feature a Neural Processing Unit (NPU) for advanced AI acceleration.
SPOT platform licensing: Ambiq intends to develop its SPOT platform into an IP and chip development platform for licensing to third parties over the next 3 to 5 years. This initiative targets specialized applications requiring power efficiency, such as data centers and automotive AI processing.

Key Q&A
Q:How does Ambiq define edge AI, and what percentage of sales fit that definition?
A:Edge AI is growing in medical, industrial edge, personal devices, smart home, and buildings. It is hard to define the exact percentage of AI use at end customers, but more than half of the business is already using intelligence on their devices, and this is expected to grow.
Q:What use cases and applications are asking for IP licensing and chiplet-type architecture, and can development be accelerated?
A:Data center, automotive, and mobile devices could benefit from SPOT technology. Development may be accelerated with enhanced R&D capabilities, more resources, and funding. A dedicated team is focusing on the 12-nanometer SPOT platform, which could help accelerate plans.
Q:What is the progress on non-wearable opportunities, particularly in medical and industrial sectors?
A:About 17% of the funnel is towards medical, industrial edge, smart home, and building. More than 20% of efforts are focused on defining Atomic edge AI in vision, showing significant progress.
Q:Were there any signs of pull-ins that impacted Q2 results?
A:There was some upside demand in Q2 due to uncertainty around tariffs, which drove revenue slightly higher than anticipated. This was the only pull-in activity observed.
Q:What are the order trends in the fitness tracker area, and how far in advance are Apollo processors shipped?
A:Orders are placed with a 16-week lead time. There is healthy growth in the fitness tracker area, and the company is optimistic about continued growth.
Q:What is the update on tariffs and their impact on the second half of the year?
A:The guidance for Q3 reflects some upside, and there is cautious optimism. Tariffs are not expected to be as impactful as previously thought, leading to a better outlook for the second half of the year.
Q:What are the expectations for gross margin in Q3?
A:Gross margin was 43% in Q2 and is expected to remain relatively stable, varying by a point or two depending on product mix and manufacturing yields.
Q:What applications are expected to generate revenue in the next four months?
A:No new applications are expected to generate revenue in the next quarter. However, AR glasses, worker safety monitors, and machine health monitors are already in the market and expected to grow.
Q:What is the update on the Atomic product development?
A:Early adopters are actively working on specifications. Activity has increased since the public offering, and progress is expected in the coming quarters.
Q:Review of Unclear Management Responses
A:Management avoided providing specific percentages for edge AI sales and did not give precise timelines for IP licensing acceleration or Atomic product availability. Additionally, they used vague language when discussing the impact of tariffs and the growth of certain applications.
