Ambiq Micro (NYSE:AMBQ) Announces Earnings Results

Ambiq Micro (NYSE:AMBQ) posted its quarterly earnings data on Tuesday. The company reported ($0.05) earnings per share (EPS) for the quarter, topping the consensus estimate of ($0.32) by $0.27, FiscalAI reports. The company had revenue of $38.14 million for the quarter. Ambiq Micro had a negative return on equity of 11.85% and a negative net margin of 37.77%. Ambiq Micro updated its Q4 2026 guidance to -0.090–0.030 EPS.

Here are the key takeaways from Ambiq Micro’s conference call:

• Third-quarter net sales rose 110% year over year to $38.1 million, marking six consecutive quarters of sequential growth. Management forecast fourth-quarter sales of $43.5 million–$44.5 million and full-year 2026 sales of about $140 million, nearly double 2025.
• Growth is broadening beyond wearables: the active customer base increased about 50% year over year, and seven customers each generated more than $1 million in quarterly sales, versus three a year ago. Ambiq expects non-wearables to reach low double digits as a share of revenue in 2028, with infrastructure and medical applications, plus AI software and models, offering additional potential.
• Supply remains tight, and some demand with short lead times went unfilled despite efforts to add capacity and expedite orders. Higher supply-chain costs are expected to keep fourth-quarter gross margin roughly flat with the third quarter.
• Third-quarter non-GAAP net loss was $1.2 million, while research and development expense rose 90% year over year as the company funds multiple product programs. Ambiq expects fourth-quarter non-GAAP operating expenses of $25.5 million–$26.5 million and a non-GAAP loss per share of $0.09–$0.03.
