Management Commentary
"Our recently completed IPO represents the next chapter of Ambiq's journey leading the edge AI revolution and bringing intelligence to edge devices," commented Fumihide Esaka, CEO of Ambiq. "Second quarter net sales increased 13.6% sequentially, reflecting solid customer demand for our highly differentiated technology platform. Ambiq's ultra-low power solutions have been incorporated into more than 280 million edge devices to-date, and we are well positioned to capitalize on the rapid growth of edge AI applications.
"One of our top priorities is the continued expansion of our technical innovation and product development roadmap. As evidence of our progress, we recently announced the expansion of our successful Apollo5 product family with the introduction of the Apollo510B wireless SoC. This solution integrates a low-power Bluetooth® radio, making it an ideal solution for always-on, connected edge devices."
Mr. Esaka concluded by stating, "Looking ahead, our well-received IPO provides us with the additional capital necessary to accelerate our strategic initiatives that include broadening our customer base as well as penetrating new end markets and geographies in support of driving long-term profitable growth."
Second Quarter 2025 Financial Results
Total net sales for the second quarter of 2025 was $17.9 million, compared to $15.7 million in the first quarter of 2025 and $20.3 million in the second quarter of 2024. The sequential increase in second quarter revenue was driven by increased customer demand and favorable product mix. The year-over-year decrease in net sales reflected Ambiq's strategic decision to diversify revenue toward higher value opportunities in geographies outside of China. In the second quarter of 2025, net sales to end customers in Mainland China were 11.5%, as compared to 42.0% in the second quarter of 2024.
Gross profit for the second quarter of 2025 was $7.2 million, or 40.1% of revenue, compared to $8.4 million, or 53.3% of revenue, in the first quarter of 2025 and $6.4 million, or 31.7% of revenue, in the second quarter of 2024. Non-GAAP gross profit for the second quarter was $7.6 million, or 42.7% of revenue, compared to $7.4 million, or 47.1% of revenue, in the first quarter of 2025 and $6.7 million, or 32.9% of revenue, in the second quarter of 2024. The sequential and year-over-year increase in non-GAAP gross profit for the second quarter of 2025 was primarily driven by a more favorable product and customer mix as Ambiq continued to execute on its strategic prioritization of geographies outside of China.
Operating expenses for the second quarter of 2025 were $16.0 million, compared to $17.1 million in the first quarter of 2025 and $17.4 million in the second quarter of 2024. Non-GAAP operating expenses for the second quarter of 2025 were $13.8 million, compared to $13.1 million in the first quarter of 2025 and $14.4 million in the second quarter of 2024.
Net loss for the second quarter of 2025 was $8.5 million, or ($18.89) per share, based on 449,785 weighted-average shares outstanding. This compares to a net loss of $8.3 million, or ($18.96) per share, in the first quarter of 2025, and net loss of $10.6 million, or ($34.59) per share, in the second quarter of 2024. The per share amounts have been adjusted to reflect a 1-for-28 reverse stock split that was effected prior to the Company's IPO. Second quarter non-GAAP net loss was $5.9 million compared to non-GAAP net loss of $5.2 million in the first quarter of 2025, and non-GAAP net loss of $7.4 million in the second quarter of 2024. The loss per share in the second quarter of 2025 was $(0.43) based on unaudited, pro forma common shares of 13.6 million as disclosed in the Company's prospectus.
Balance Sheet
Total cash and cash equivalents were $47.5 million as of June 30, 2025. Subsequent to the end of the second quarter, Ambiq completed its IPO and received net proceeds of $97.2 million from the issuance and sale of 4.6 million shares of common stock.
Third Quarter Business Outlook
Ambiq's current expectations for the third quarter of 2025 ending September 30, 2025, include the following:
- Net sales within a range of $17.5 million to $18.0 million
- Non-GAAP loss per share within a range of ($0.35) to ($0.28) based on unaudited pro forma common shares of approximately 18.2 million as disclosed in the Company's prospectus.
Ambiq's third quarter 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 to net loss, the most directly comparable GAAP measure, without unreasonable effort due to the high variability with respect to the impact of items such as income taxes, depreciation and amortization, stock-based compensation expense, gain on nonmonetary transaction, severance costs, initial public offering (IPO) and other transaction costs, warrant valuation and other items that are excluded from this non-GAAP measure.

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 net loss and non-GAAP gross profit, both non-GAAP financial measures, to help make strategic decisions, establish budgets and operational goals for managing the business, analyzing financial results, and evaluating business performance. 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 transaction, severance costs, transaction costs and warrant valuation. Ambiq defines non-GAAP gross profit as gross profit adjusted to exclude expenses not directly attributable to gross profit, such as depreciation and amortization, gain on nonmonetary transaction, and stock-based compensation.
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 net loss, non-GAAP gross profit may not be comparable to similarly titled measures reported by other companies due to differences in the way that these measures are calculated. Non-GAAP net loss, non-GAAP gross profit 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, net loss and gross profit calculated in accordance with GAAP.
Forward-Looking Statements
The statements contained in this press release that are not historical facts are forward-looking statements. You can identify forward-looking statements because they contain words such as "believes," "expects," "may," "will," "should," "seeks," "intends," "plans," "estimates," or "anticipates," or similar expressions which concern our strategy, plans, projections or intentions. These forward-looking statements may be included throughout this press release, and include, but are not limited to, statements relating to Ambiq's expectations around its strategic initiatives and expected third quarter business outlook. By their nature, forward-looking statements are not statements of historical fact or guarantees of future performance and are subject to risks, uncertainties, assumptions or changes in circumstances that are difficult to predict or quantify including those described in the section titled "Risk Factors" in Ambiq's prospectus filed with the Securities and Exchange Commission ("SEC") on July 31, 2025, as well as in other filings Ambiq may make with the SEC in the future. 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. Any forward-looking statement in this press release speaks only as of the date of this release. Ambiq undertakes no obligation to publicly update or review any forward-looking statement, whether as a result of new information, future developments or otherwise, except as may be required by any applicable securities laws.
