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."

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 availabilityNon-GAAP gross margin between 46.5% and 47.5%, driven by favorable mix and manufacturing efficienciesNon-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 investmentsNon-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.
