The latest verified development

Ambiq Micro, Inc. (NYSE:AMBQ), a designer of ultra-low-power semiconductors, last reported results in August 2026 for the quarter ended 30 June. Chief executive Fumihide Esaka said Ambiq expects Demand to strengthen even further in the second half of the year, while noting Supply constraints across the semiconductor industry.

Second-quarter results

Net sales were $33.9 million, up about 90% year on year and 35% from the previous quarter. Those growth rates imply sales of roughly $17.8 million a year earlier and $25.1 million in the first quarter.

GAAP gross margin was 45.0%, up 4.9 percentage points, and non-GAAP gross margin was 47.2%, up 4.5 points. Gross Profit more than doubled. The GAAP net loss was $7.1 million, or $0.32 per share, and the non-GAAP net loss was $1.8 million, or $0.07 per share. GAAP operating expenses were $24.0 million and non-GAAP operating expenses were $19.4 million.

The gap between GAAP and non-GAAP results is sizeable relative to the loss. The two net-loss figures differ by $5.3 million and the operating-expense figures by $4.6 million.

Funding and balance sheet

Cash and equivalents were $366.8 million at 30 June 2026, after a June public offering that raised about $168 million in net proceeds.

The offering matters for shareholders because issuing shares can increase the share count. The weighted average share count assumed in guidance is 24.17 million.

Listing history

Ambiq completed its initial public offering on 30 July 2025, so it has been public for just over a year and has a short trading record.

Third-quarter guidance

For the third quarter of 2026, Ambiq guided to net sales of $36.0 million to $37.0 million, non-GAAP gross margin of 46.5% to 47.5% and non-GAAP operating expenses of $24.0 million to $25.0 million. It guided to a non-GAAP net loss per share of $0.20 to $0.12. At the midpoint, sales would be about 7.7% above the second quarter.

Guided non-GAAP operating expenses are well above the $19.4 million reported for the second quarter, which explains why the guided loss per share is wider than the latest result despite higher sales.

Gross margin, spending and supply at Ambiq

Third-quarter sales guided at a $36.5 million midpoint meet non-GAAP operating expenses of $24.0 million to $25.0 million, up from $19.4 million. The guided loss per share of $0.20 to $0.12 therefore turns on gross margin holding near 47%.
