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.

Fourth Quarter Business Outlook

Ambiq’s current expectations for the fourth quarter of 2025 ending December 31, 2025, include the following:

• Net sales within a range of $18.5 million to $19.5 million
• Non-GAAP loss per share within a range of ($0.44) to ($0.34) based on 18.2 million pro forma shares, which represents the company's post-IPO common shares outstanding¹

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 per share to net loss per share, 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 attributable to common stockholders, non-GAAP gross profit, non-GAAP gross margin, non-GAAP operating expenses, non-GAAP R&D expenses, non-GAAP SG&A expenses, non-GAAP net loss attributable to common stockholders and pro forma non-GAAP loss per share attributable to common stockholders. These non-GAAP financial measures help 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, gain on nonmonetary transaction, and stock-based compensation. 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, IPO-related bonus and IPO and other transaction costs Ambiq defines non-GAAP net loss attributable to common stockholders as net loss attributable to common stockholders 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, IPO-related bonus, IPO and other transaction costs and warrant valuation. Ambiq defines pro forma non-GAAP loss per share attributable to common stockholders as non-GAAP net loss attributable to common stockholders divided by pro forma common shares outstanding, which gives effect to the automatic conversion of all outstanding redeemable convertible preferred stock, exercise of warrants to purchase common stock and settlement of IPO vesting RSUs into common stock that occurred immediately prior to the completion of our initial public offering, as well as the issuance of shares in our initial public offering, as if such transactions had occurred on July 1, 2025.

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, non-GAAP net loss attributable to common stockholders and pro forma non-GAAP loss per share attributable to common stockholders 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.
