ⓘ This article is third-party content and does not represent the views of this site. We make no guarantees regarding its accuracy or completeness.

Delivered record quarterly net sales, increasing approximately 90% year-over-year, driven by strong demand for edge AI solutions

Gross profit more than doubled year-over-year on higher net sales and margin expansion

Expect third quarter net sales of $36.0 million to $37.0 million, which would represent the sixth consecutive quarter of sequential growth

Ambiq Micro, Inc. (“Ambiq”) (NYSE: AMBQ), a technology leader in ultra-low-power semiconductor solutions for edge AI, today announced financial results for the second quarter 2026.

Second Quarter 2026 and Recent Highlights

  • Delivered strong net sales on growing edge AI demand momentum: Net sales increased approximately 90%, year-over-year, driven by accelerating edge AI demand across customers, end markets and products.
  • Gross profit outpaced net sales growth: GAAP gross profit increased approximately 113% and non-GAAP gross profit increased approximately 109% year-over-year, with GAAP gross margin and non-GAAP gross margin expanding by 490 basis points and 450 basis points respectively.
  • Enhanced financial flexibility to capitalize on growth opportunities ahead: Completed an upsized public offering in June, raising approximately $168 million in net proceeds.
  • Expanded edge AI software stack: Launched heliaCORE and compressionKIT to accelerate customers' deployment of small footprint and energy efficient AI models on the Apollo SoC families. We also announced heliaPROFILER, a new open-source profiling tool that speeds customers' AI model development.
  • Strengthened global capital markets access: Announced a dual listing on the Singapore Exchange Main Board under ticker AMQ, expanding investor reach across Asia and reinforcing our long-term growth strategy in the global semiconductor market.

Management Commentary

“Since the start of the year, we have seen a step-change in demand, further reinforcing our belief in the scale and durability of the edge AI opportunity. That momentum drove our net sales up approximately 90% year over year, marking our fifth consecutive quarter of growth, and we expect demand to strengthen even further in the second half of the year,” said Fumihide Esaka, CEO of Ambiq. “Given the rapid acceleration in AI demand, we and the broader semiconductor industry are facing supply constraints. Even with this, we are on pace to more than double net sales in the second half of 2026 compared to last year. We are acting decisively to expand capacity, support our customers and capture the full opportunity we see to enable the next generation of intelligent edge products."

*Non-GAAP gross profit, non-GAAP gross margin, non-GAAP operating expense and non-GAAP net loss are non-GAAP financial measures. See "Non-GAAP Financial Measures" below for definitions of each of these measures, and the tables accompanying this press release for reconciliations of these measures to their most comparable GAAP measure.

Third Quarter Business Outlook1

Ambiq’s current expectations for the quarter ending September 30, 2026, include the following:

  • Net sales within a range of $36.0 million to $37.0 million, reflecting accelerating demand for edge AI, partially constrained by industry-wide supply availability
  • Non-GAAP gross margin between 46.5% and 47.5%, driven by favorable mix and manufacturing efficiencies
  • Non-GAAP operating expense of $24.0 million to $25.0 million, reflecting investments to support product development and our strategic growth priorities, including planned intellectual property investments
  • Non-GAAP net loss per share within a range of ($0.20) to ($0.12) based on a weighted average share count of 24.17 million shares outstanding

1Ambiq's financial outlook is based on assumptions that it believes to be reasonable as of the date of this release, but may be materially affected by many factors, as discussed below in "Forward-Looking Statements." Actual results may vary from the guidance and the variations may be material. We undertake no intent or obligation to publicly update or revise this outlook, whether as a result of new information, future events or otherwise, except as required by law. The Company is unable to include a reconciliation of forward-looking non-GAAP net loss per share, non-GAAP gross margin and non-GAAP operating expense to the most directly comparable GAAP measure without unreasonable effort due to the high variability with respect to the impact of items such as depreciation and amortization and, stock-based compensation expense and other items that are excluded from these non-GAAP measures.

Non-GAAP Financial Measures

Ambiq supplements its reporting of financial information determined under generally accepted accounting principles in the United States of America (GAAP), including the use of non-GAAP gross profit, non-GAAP gross margin, non-GAAP operating expenses, non-GAAP R&D expenses, non-GAAP SG&A expenses and non-GAAP net loss. These non-GAAP financial measures help management make strategic decisions, establish budgets and operational goals for managing the business, analyzing financial results, and evaluating business performance. Ambiq defines non-GAAP gross profit as gross profit adjusted to exclude expenses not directly attributable to gross profit, such as depreciation and amortization, stock-based compensation and gain on nonmonetary transactions. Ambiq defines non-GAAP gross margin as non-GAAP gross profit as a percentage of net sales. Ambiq defines non-GAAP operating expenses, non-GAAP R&D expenses and non-GAAP SG&A expenses as operating expenses, R&D expenses and SG&A expenses, as applicable, adjusted to exclude expenses not directly attributable to operating expenses, R&D expenses and SG&A expenses, as applicable, such as depreciation and amortization, stock-based compensation, severance costs, and IPO and other transaction costs, as applicable. Ambiq defines non-GAAP net loss as net loss adjusted to exclude expenses not directly attributable to the performance of operations, such as income taxes, depreciation and amortization, stock-based compensation, gain on nonmonetary transactions, severance costs, IPO and other transaction costs and warrant valuation.

Ambiq believes these non-GAAP financial measures provide additional tools for investors to use in comparing core business and results of operations over multiple periods with other companies in the industry, many of which present similar non-GAAP financial measures. However, Ambiq's presentation of non-GAAP gross profit, non-GAAP gross margin, non-GAAP operating expenses, non-GAAP R&D expenses, non-GAAP SG&A expenses, and non-GAAP net loss may not be comparable to similarly titled measures reported by other companies due to differences in the way that these measures are calculated. These non-GAAP measures have limitations, and should not be considered as the sole measures of our performance and should not be considered in isolation from, or as a substitute for, the most comparable measure calculated in accordance with GAAP.

Ambiq's expectations, beliefs and projections are expressed in good faith and Ambiq believes there is a reasonable basis for them. However, there can be no assurance that management's expectations, beliefs and projections will result or be achieved and actual results may vary materially from what is expressed in or indicated by the forward-looking statements.
