© 2026 ambiq | all rights reserved Legal Disclaimer 2 Forward-Looking Statements This presentation includes “forward-looking statements” within the meaning of the “safe harbor” provisions of the United States Private Securities Litigation Reform Act of 1995. Forward-looking statements may be identified by the use of words such as “future,” “growth,” “opportunity,” “well-positioned,” "forecast," "intend," "seek," "target," “anticipate,” “believe,” “expect,” “estimate,” “plan,” “outlook,” “project,” “may,” “could,” and “should,” and other similar expressions that predict or indicate future events or trends or that are not statements of historical matters. These forward-looking statements may be included throughout this presentation, and include, but are not limited to, statements relating to Ambiq Micro’s (“Ambiq,” the “Company,” “we,” “us” or similar terms) expectations around its strategic initiatives, growth trajectory and expected third quarter and full year 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 10-K, as well as in other filings we may make with the SEC in the future. Our expectations, beliefs and projections are expressed in good faith and we believe there is a reasonable basis for them. However, there can be no assurance that our 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 presentation speaks only as of the date of this presentation. We undertake 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. 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 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 as operating expenses adjusted to exclude expenses not directly attributable to operating expenses 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 transactions 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 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.

© 2026 ambiq | all rights reserved Financial Outlook1 17 3Q 2026 Outlook Net Sales $36.0M - $37.0M Non-GAAP Gross Margin2 46.5% - 47.5% Non-GAAP Op Ex2 $24.0M - $25.0M Non-GAAP Net Loss Per Share2 $(0.20) – $(0.12) 1. As of August 11, 2026. 2. Ambiq'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 inclu de 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. 3Q26 Drivers ▪ Expect underlying edge AI demand to further strengthen in 2H26 ▪ Net sales constrained by industry-wide supply availability ▪ Working closely with supply chain partners to improve supply flexibility ▪ Gross margin benefitting from favorable mix and manufacturing efficiencies FY26 Expectations ▪ Approximately $135M in full-year net sales ▪ 2H26 net sales more than doubling year-over-year, even with supply constraints ▪ Modest year-over-year improvement in full year non-GAAP gross margin ▪ Operating expenses of approximately $85M, including $7 - $10M of planned IP investments
