Ambiq Micro (AMBQ) stock jumped 30% to $59.51 on Tuesday after the Texas-based chip maker posted first-quarter results that beat Wall Street estimates on both the top and bottom lines.

Ambiq Micro, Inc., AMBQ

Q1 net sales came in at $25.1 million, up 59% from a year ago. Analysts had expected $21.5 million. The adjusted loss per share was 25 cents, an improvement from a loss of 38 cents in the same period last year and better than the consensus estimate of 36 cents.

The stock has more than doubled since Ambiq went public last July at an offering price of $24 a share.

Its products power smart watches, industrial sensors, portable game consoles, and smart-home devices. Over 80% of units shipped in Q1 were running AI algorithms.

Q2 Guidance Tops Estimates

For the second quarter, Ambiq is forecasting net sales of $31 million to $32 million. That came in well above Wall Street’s estimate of $25.7 million.

The company continues to operate at a loss. CFO Jeff Winzeler said on the earnings call that Ambiq would need around $47 million in quarterly revenue to break even.

Winzeler said the company is “hopeful” it can reach that level by mid-2028, or potentially as early as the end of 2027.

The company’s SPOT platform — its ultra-low-power chip architecture — is at the center of its edge AI push. Ambiq says it is expanding into a broader range of form factors, customers, and end markets.

A Bright Spot on a Dark Day for Chips

Ambiq’s strong print stood out on an otherwise rough day for the semiconductor sector.

The iShares Semiconductor ETF (SOXX) fell 5.8% on Tuesday, putting it on track for its worst single-day drop since October, according to Dow Jones Market Data.

While most chip names were in the red, AMBQ bucked the trend by a wide margin.

Q1 non-GAAP EPS came in at a loss of 25 cents versus the consensus of a loss of 36 cents. Revenue of $25.1 million beat the consensus of $21.49 million.

Ambiq’s Q2 net sales forecast of $31–$32 million represents continued sequential growth as it works toward its breakeven target.
