Ambiq Micro, Inc. reported its financial results for the second quarter of 2025, revealing a decline in revenue and continued net losses. The company generated net sales of $17.9 million for the three months ended June 30, 2025, a decrease of 11.7% from $20.3 million in the same period of 2024. For the first half of 2025, net sales totaled $33.6 million, down 5.2% from $35.5 million in the prior year. The net loss for the second quarter was $8.5 million, compared to a loss of $10.6 million in the same quarter of 2024. The accumulated deficit as of June 30, 2025, stood at $337.0 million.
The company attributed the revenue decline primarily to a strategic shift away from its customer base in Mainland China, which has historically accounted for a significant portion of its sales. In the second quarter of 2025, only 12% of net sales were derived from customers in Mainland China, a notable drop from 42% in the same quarter of 2024. This shift is part of Ambiq's broader strategy to focus on markets such as medical, industrial, and smart home applications, which are expected to yield better margins.
Operationally, Ambiq Micro has made significant investments in research and development, with expenses totaling $8.9 million for the second quarter, slightly down from $9.4 million in the previous year. The company continues to prioritize product development to enhance its ultra-low power semiconductor solutions, which are critical for edge AI applications. The total operating expenses for the second quarter were $15.9 million, down from $17.4 million in the same period last year, reflecting a focus on cost management.
As of June 30, 2025, Ambiq Micro had cash and cash equivalents of $47.5 million, a decrease from $60.9 million at the end of 2024. The company reported a cash flow deficit of $10.5 million from operating activities for the first half of 2025, compared to $5.1 million in the same period of 2024. The company anticipates continued losses and negative cash flows until it can generate significant sales from its products currently in development.
Looking ahead, Ambiq Micro is focused on expanding its market presence and enhancing its product offerings. The company recently completed its initial public offering (IPO) on July 31, 2025, raising $97.2 million in net proceeds, which it plans to use to support its growth strategy and operational needs. However, the company remains cautious about the macroeconomic environment, including geopolitical tensions and supply chain challenges, which could impact its future performance.
