Ambiq Sales Jump 110% in Third Quarter; Adjusted Loss per Share Reaches $0.05

Key Facts

Ambiq Micro reported results on November 10 for the third quarter ended September 30, 2026, recording year-over-year net sales growth of about 110%, according to a company statement. The company attributed the increase to strong demand across customers, product families and their various form factors. CEO Fumihide Esaka said the quarter marked the sixth consecutive period of sequential net sales growth. Esaka linked the trend to customer demand and strong supply-chain partnerships that helped the company secure production capacity. The results put sales growth at the forefront of the company's performance, while GAAP profitability remains negative.

Net loss was $7.056 million, or $0.29 per share under GAAP, compared with a net loss of $9.002 million and $0.72 per share in the third quarter of 2025. On a non-GAAP basis, the company posted a loss per share of $0.05, versus $0.22 in the year-earlier period. These are two different measures of profitability: the first follows generally accepted accounting principles, while the second is the adjusted measure reported by the company. The year-over-year comparison shows a narrower loss at the net income level and in loss per share under both measures. The company did not specify in its official results how much it exceeded analysts' estimates.

Gross profit improved alongside sales growth, with GAAP gross profit rising 132% year over year and non-GAAP gross profit increasing 128%. The GAAP gross margin widened by 440 basis points, while the non-GAAP margin widened by 390 basis points. Ambiq said its active customer base expanded by about 50% from a year earlier, in line with the broader demand the company reported across product lines and customers. The number of customers with sales exceeding $1 million each during the quarter also rose to 7, from 3 in the third quarter of 2025. These indicators show a broadening sales base alongside improvements in gross profit and margins.

As it expands its product lineup, Ambiq said the launch of heliaPROFILER and heliaAOT 1.0 marked its seventh software product launch or major release in 2026. The company said more than 300 million of its devices have been shipped worldwide. Its balance sheet showed cash and cash equivalents of $363.452 million on September 30, 2026, up from $140.275 million on December 31, 2025. This comes as the company plans to continue spending on product development and preparing new products for production. It said fourth-quarter expenses will include production-readiness costs for Atomiq110 and Apollo340.

Ambiq expects non-GAAP operating expenses of $25.5 million to $26.5 million in the fourth quarter of 2026, including production-readiness costs for Atomiq110 and Apollo340 and product development investments. It also expects non-GAAP net loss of $0.09 to $0.03 per share, based on a weighted average of 24.6 million shares outstanding. The company said non-GAAP gross margin in the coming quarter will be close to its third-quarter level, as manufacturing efficiency and product mix offset supply-chain cost pressures. Investors are therefore watching whether sales growth can continue alongside product spending and supply costs. AMBQ shares closed at $45.77 in the November 9 session, according to EL7 data.

On the outlook for sales, Esaka said the company expects a meaningful increase in net sales in the fourth quarter, along with another year of strong growth in 2027. The company did not provide a target for next quarter's revenue in its statement, but linked its outlook to continued demand and supply partnerships. The expense and expected-loss guidance is key to assessing this trajectory, as it points to continued investment even as sales are expected to rise. The outlook for steady non-GAAP margins also reflects the expectation that manufacturing efficiency and product mix will offset supply-chain cost pressures. Fourth-quarter results will be the next milestone in assessing the company's ability to turn a broader customer base and sales growth into sustained improvement in profitability.
