You should carefully read the "Risk Factors" sections of this Quarterly Report on Form 10-Q and our Annual Report to gain an understanding of the important factors that could cause actual results to differ materially from forward-looking statements. Please also see the section titled "Special Note Regarding Forward-Looking Statements".

Overview

We are a pioneer and leading provider of ultra-low power semiconductor solutions designed to address the significant power consumption challenges of general purpose and Artificial Intelligence (AI) compute - especially at the edge.

Our customers rely on Ambiq to deliver AI compute closer to end users (edge environments) where power consumption challenges are the most severe. We seek to drive growth in AI adoption at the edge in the personal devices, medical/healthcare, industrial edge and smart home and building markets and continue to set new standards in edge AI performance and power efficiency. Over time, we expect to integrate our ultra-low power technology into additional chip products that benefit from greater power efficiency, including high-performance compute applications such as AI data centers and automotive.

To date, a majority of AI compute has been deployed in data centers due to its large physical scale and the need for wall plug energy, as AI compute requires enormous and steady energy resources. At the edge, however, power limitations have been especially acute due to small device size and limited battery life. We believe this greatly constrains the potential of AI to improve our daily on-the-go lives. Enabling AI at the edge, where the action takes place, with vastly improved power efficiency, will allow faster real-time decision-making due to data proximity, greater data privacy, higher energy efficiency from reduced network usage and less dependence on constant costly connections to the cloud. We believe new AI use cases will only be possible if edge devices are much more power efficient.

Our proprietary Sub-threshold Power Optimized Technology (SPOT®) platform is designed to fundamentally and cost-effectively reduce power consumption of battery- and wireline-powered devices alike. Depending on the application, devices incorporating SPOT demonstrate a two to five times reduction in power consumption compared to conventional integrated circuit designs. SPOT is a ground-breaking approach at the chip design level that incorporates sub- and near-threshold hardware, without using expensive manufacturing processes.

We provide a full stack solution encompassing tightly integrated hardware and software. Our solutions include a diverse family of systems-on-chip (SoCs) and the software required to enable on-chip AI processing, general compute, sensing, security, storage, wireless connectivity and advanced graphics. Our SoC solutions deliver compute at a very small fraction of the power consumed by our competitors' products.

Our ultra-low power SoCs serve a wide range of markets requiring on-device and real-time AI, including smartwatches and fitness trackers, augmented and virtual reality (AR/VR) glasses, smart rings, digital health monitors, security systems and access control, livestock tracking, crop monitoring and factory automation.

Body-worn AI devices drive a significant portion of our revenue today and often require weeks of battery life while running advanced AI-driven features. These devices increasingly offer on-chip AI-powered features such as speech recognition, domain-specific language models, image and video processing and sensing, further straining power consumption, which our solutions are positioned to address. However, as we continue to expand into new end markets, we expect there to be a meaningful growth opportunity for non-personal devices in 2026.

As global demand for our SoC solutions accelerates, our sales and marketing efforts are increasingly focused on our end customers in target geographies such as the United States, Europe and Asia (ex-Mainland China).

For the six months ended June 30, 2026 and 2025, we generated net sales of $59.0 million and $33.6 million, respectively, and net loss of $17.3 million and $16.8 million, respectively. As of June 30, 2026, we had an accumulated deficit of $374.0 million.

Follow-On Offerings

On January 26, 2026, we completed a follow-on offering of 2,679,600 shares of common stock, at a public offering price of $31.00 per share, of which 2,636,651 shares were issued and sold by our Company and 42,949 shares were sold by certain selling stockholders. We received net proceeds of $75.3 million after deducting underwriting discounts and commissions of approximately $5.0 million and offering expenses of approximately $1.5 million. We did not receive any proceeds from the sale of shares by the selling stockholders.

On June 25, 2026, we completed a follow-on offering of 2,300,000 shares of common stock, at a public offering price of $78.00 per share. We received net proceeds of $167.9 million after deducting underwriting discounts and commissions of $10.8 million and offering expenses of approximately $0.7 million.

Key Factors Affecting Our Business

We believe that the growth of our business and our future success are dependent upon many factors including those described under "Risk Factors" and elsewhere in this Quarterly Report on Form 10-Q and our Annual Report and the following key factors. While these factors present significant opportunities for us, they also pose challenges that we must successfully address in order to sustain the growth of our business and enhance our results of operations.

End Customer Concentration

We believe that our operating results for the foreseeable future will continue to depend to a significant extent on sales attributable to certain end customers. Our top three end customers collectively represented approximately 78% and 75% of our total net sales for the three and six months ended June 30, 2026, respectively. We expect to continue to expand our customer base with new product development to reduce customer concentration. We have demonstrated strong end customer growth with technology leaders validating our technology platform and our robust product offerings. We work with our end customers at the front end of their design cycles, helping them develop next-generation products. The collaborative nature of these relationships provides us with enhanced visibility into our end customers' future requirements, allowing us to expand our business and increase our content in future products.

Product Development and Adoption

We develop and sell leading-edge ultra-low power SoCs, tightly bundled with software and various other solutions that combine 32-bit microcontrollers (MCUs) with wireless connectivity and additional circuitry, such as graphics processing units, serial interfaces, and analog-to-digital interfaces. Our success is dependent on end customers adopting our new technology and preferring our products over competing offerings or technologies.

Our current end customer products are characterized by rapidly changing technologies, industry standards and technological obsolescence. We work closely with our end customers to understand their product roadmaps and strategies to forecast their future needs, which significantly influence our technology roadmap and development priorities. Our revenue performance is dependent on our ability to continually develop and introduce new products to meet the changing technology and performance requirements of the market and our end customers. Maintaining our competitive advantage is critical to our financial performance. We continue to expect to make significant investments in research and development, and our research and development expenses in a particular period may be significantly impacted by a specific product launch or engineering initiatives that we have undertaken to maintain our competitiveness or expand our product portfolio.

Unit Price and Volume and Gross Margins

Our revenue is driven by the number of units and average selling price (ASP) of our products, which can fluctuate from period to period based on the timing of our product lifecycle. The ASPs of our products vary significantly. While the ASP of any individual product generally decreases over time, our average ASPs have historically increased as we continue to introduce new higher-end products with higher ASPs.

Our product gross margins may fluctuate from period to period due to changes in our average selling price per unit due to new product launches and existing product mix with our end customer base. Our gross margins are also impacted by any changes to our manufacturing yield and wafer assembly and testing costs. We routinely experience increased prices for silicon wafers, packaging, printed circuit boards and testing costs, which are used in our manufacturing process. As a result, our gross margins are impacted by our ability to offset any increases in our cost structure through increased prices, productivity improvements or other means.

Cyclical Nature of the Semiconductor Industry

The semiconductor industry is highly cyclical and is characterized by constant and rapid technological change, rapid product obsolescence, price erosion, evolving standards, short product life cycles and wide fluctuations in product supply and demand. Historically, the industry has experienced significant downturns during global recessions. These downturns have been characterized by diminished product demand, production overcapacity, high inventory levels and accelerated erosion of average selling prices. Furthermore, any significant upturn in the semiconductor industry could result in increased competition for access to third-party wafer fabrication and assembly capacity. We are dependent on the availability of this capacity to manufacture and assemble our products and

we can provide no assurance that adequate capacity will be available to us in the future. Any downturns or upturns in the semiconductor industry could harm our business, financial condition and results of operations. Our revenue has historically been subject to some seasonal variation. However, with rapid changes in technology development and our markets, the seasonal factors that affect our business may change from time to time.

Geographical Concentration

As we focus on creating meaningful benefits to our end customers for their edge AI capabilities, we are shifting our geographic concentration. Historically, our sales were significantly concentrated with end customers in Mainland China. Given geopolitical concerns, subsidized competitors creating a price sensitive environment in Mainland China and our desire to service new markets in medical/healthcare, industrial edge and smart home and buildings, we continue to prioritize our management and sales efforts toward other meaningful geographies. During both the three and six months ended June 30, 2026, our net sales to end customers in Mainland China were 13.7%, as compared to 11.5% and 9.0% during the three and six months ended June 30, 2025, respectively. While this represents an increase, certain sales will continue to be evaluated if they represent higher-margin opportunities.

Additionally, we source all of our wafers from TSMC, located in Taiwan. Deterioration in the political, social, business or economic conditions in the jurisdictions in which TSMC or other suppliers operate could slow or halt product shipments or disrupt our ability to manufacture, package, test or post-process products. In response, we could be forced to transfer our manufacturing, packaging, testing and post-processing activities to more stable, and potentially more costly, regions or find alternative suppliers. Therefore, our supply of wafers and other critical components may be materially and adversely affected by certain political, social and economic risks which could adversely affect our business, financial condition and results of operations.

Economic Volatility

Our sales and gross margin depend significantly on general economic conditions and the demand for products in the markets where our end customers compete. Weaknesses in the global economy and financial markets, including the impact of new and ongoing global conflicts may in the future lead to lower demand for our end customers' products that incorporate our products. Volatile and/or uncertain economic conditions, including increased inflation rates and the imposition of tariffs in the United States and abroad can adversely impact sales and gross margin and make it difficult for us to accurately forecast and plan our future business activities. In addition, any disruption in the credit markets could impede our access to capital, which could be further adversely affected if we are unable to obtain or maintain favorable credit ratings. If we have limited access to additional financing sources, we may be required to defer capital expenditures or seek other sources of liquidity, which may not be available to us on acceptable terms or at all.

The global macroeconomic environment could also be negatively affected by, among other things, increased U.S. disputes with countries that are existing trade partners, supply chain weaknesses and instability in the geopolitical environment in Asia, Europe and the Middle East. Deterioration in economic factors arising from trade disputes between the United States and China, in particular, could have an adverse impact on our financial results given its customer concentrations in both countries. Such challenges have caused, and may continue to cause, recession fears and fluctuations in interest rates and foreign exchange volatility.

Components of our Operating Results

Net Sales

We are a products-focused business. Our net sales are recognized when control of our products is transferred to our customers for consideration that we expect to receive for our products, net of returns and allowances. Our net sales are driven by the average selling price of our products, product volumes and mix of products sold. Our end customers represent the actual user of our product, whether sold directly to or through a distributor.

Cost of Sales

Our cost of sales includes the cost of purchasing finished wafers manufactured by independent foundries and costs associated with the assembly, testing, shipping and handling of products along with allocated costs for salary, stock-based compensation and related benefits for personnel involved in the manufacturing of our products. Cost of sales also includes depreciation for equipment and photomasks supporting the manufacturing process, write downs of inventory, sell-through of products previously reserved for, IP royalties, amortization of IP licensing fees, logistics, quality assurance, warranty and other costs incurred by us.

Operating Expenses

Our operating expenses are categorized as research and development costs or selling, general and administrative expenses and classified based on the descriptions below:

Research and Development Costs

Research and development costs are expensed as incurred. Research and development costs consist primarily of compensation-related expenses, including salaries, benefits, and stock-based compensation expense for employees that support our research and

development organization, external consulting and services costs, licensing fees, equipment tooling and allocations of other costs we incur. Assets purchased to support our ongoing research and development activities are capitalized when related to products that have achieved technological feasibility or have an alternative future use and are amortized over their estimated useful lives. We expect research and development costs to increase as a public company as we intend to reinvest our proceeds into our future product development and the expansion of our current product offerings.

Selling, General and Administrative Expenses

Our selling, general and administrative expenses consist of compensation-related expenses, including salaries, benefits, and stock-based compensation expense for employees that support our sales, finance, human resources, marketing, and other corporate functional support. Selling, general and administrative also includes insurance costs, rent and lease expenses, travel and entertainment, and general corporate expenses, such as accounting, audit, legal, regulatory, and tax compliance. We expect selling, general and administrative expenses to increase in absolute dollars as we incur increased accounting, legal and professional fees and other costs associated with being a public company.

Other Income, net

Other income, net reflects interest income generated from our cash and cash equivalents on hand being invested in interest-bearing accounts. Our other expenses are principally the mark-to-market valuation of our warrant liabilities and the impact of foreign exchange gains and losses on our results.

Provision for Income Taxes

Our provision for income taxes includes federal, foreign and state taxes. Income taxes are accounted for using the asset and liability method.

The increases were primarily due to an increase in the average selling price for our products coupled with an increase in demand for our products due to new product launch ramps.

Gross margin increased 490 basis points to 45.0% for the three months ended June 30, 2026 compared to the corresponding prior year period, primarily due to an increase in average selling price for our products. Gross margin decreased 190 basis points to 44.4% for the six months ended June 30, 2026 compared to the corresponding prior year period, primarily due to a non-monetary gain of $1.6 million in the first quarter of 2025, which did not repeat in 2026, partially offset by an increase in the average selling price for our products.

Average selling price increased for the three and six months ended June 30, 2026 primarily due to our customers transitioning to our new products.

The overall increases in research and development expenses were primarily attributable to increased intellectual property development and technology spend in addition to higher contractor and compensation-related costs, including both variable compensation for our internal incentive compensation program and share-based compensation expenses associated with RSU grants after our IPO. For the three and six months ended June 30, 2026 we hired an additional 15 and 23 employees, respectively, in line with our development plans.

Selling, general and administrative expenses during the three months ended June 30, 2026 increased $2.8 million, or 39.4%, to $9.9 million compared to the corresponding prior year period. The increase was primarily due to higher share-based compensation expenses associated with RSU grants after our IPO, as well as higher variable compensation for our internal incentive compensation program, internal and third-party sales commissions, which increased with higher revenue earned during the quarter, and incremental costs associated with our ongoing obligations as a public company, including audit, legal and compliance-related fees.

During the six months ended June 30, 2026, selling, general and administrative expenses increased $4.1 million, or 26.4%, to $19.6 million compared to the corresponding prior year period, primarily attributable to the above items, partially offset by the absence of non-capitalizable IPO expenses incurred during the first quarter of 2025.

The increases were primarily attributable to higher interest income earned on greater cash proceeds raised through our IPO and subsequent follow-on offerings in January and June 2026.

Provision for Income Taxes

We recorded minimal income tax expense for the three and six months ended June 30, 2026 on a pre-tax loss of $7.1 million and $17.3 million, respectively, yielding an effective tax rate of 0.01% and 0.02%, respectively. Our effective tax rate was lower than the U.S. statutory rate of 21%, principally due to the change in valuation allowance. We recorded minimal income tax expense for the three and six months ended June 30, 2025 on a pre-tax loss of $8.5 million and $16.8 million, respectively, yielding an effective tax rate of 0.17% and 0.11%, respectively.

Liquidity and Capital Resources

We have funded operations primarily through equity financings and cash from operations. We have historically incurred losses and negative cash flows from operations and anticipate continuing to incur losses as we heavily invest in product development. During the six months ended June 30, 2026, we reported a net loss of $17.3 million and had an operating cash flow deficit of $20.7 million. As of June 30, 2026, we had cash and cash equivalents totaling $366.8 million and accumulated deficit of $374.0 million.

In January 2026, we completed a follow-on offering, which resulted in net proceeds of $75.3 million after deducting underwriting discounts and commissions of approximately $5.0 million and offering expenses of approximately $1.5 million.

In June 2026, we completed a follow-on offering, which resulted in net proceeds of $167.9 million after deducting underwriting discounts and commissions of $10.8 million and offering expenses of approximately $0.7 million.

In addition to the net proceeds from our IPO and our subsequent follow-on offerings, we continue to improve our operating margins through revenue growth and strategic transition to more profitable opportunities. Our principal use of cash is to fund our operations, invest in research and development to support our growth and other general corporate needs.

We believe that our cash on hand and anticipated cash from operations will be sufficient to finance our operations for at least the next twelve months from the date of this Quarterly Report on Form 10-Q.

Our future capital requirements will depend on many factors including our growth rate, the timing and extent of our selling, general and administrative and research and development expenditures, and the continuing market acceptance of our products. Additionally, we anticipate continued additional costs associated with being a public company. If our current financial resources are not sufficient to satisfy our liquidity requirements, we may be required to seek additional financing. If we raise additional funds by issuing equity securities, our stockholders will experience dilution. Debt financing, if available, may contain covenants that significantly restrict our operations or our ability to obtain additional debt financing in the future. In the event that we need to borrow funds or issue additional equity, we cannot guarantee that any such additional financing will be available on terms acceptable to us, if

at all. If we are unable to raise additional capital when we need it, our business, results of operations and financial condition would be adversely affected.

Cash Flows from Operating, Investing and Financing Activities

Changes in the net cash provided by (used in) our operating, investing and financing activities for the six months ended June 30, 2026 and 2025 are set forth in the following table:

Operating Activities

For the six months ended June 30, 2026, cash flows used in operations was $20.7 million, primarily driven by the cash components of our net loss and $13.9 million of unfavorable changes in working capital driven primarily by building $12.4 million in inventory, partially offset by $1.4 million due to the timing of our sales to customers and payments to our vendors.

For the six months ended June 30, 2025, cash flows used in operations was $10.5 million. Operating cash flow generated during the six months ended June 30, 2025 was related to the cash components of our net loss and approximately $2.0 million of favorable changes in working capital driven primarily by $0.8 million of lower inventory purchases offset by approximately $2.8 million due to the timing of our sales to customers and payments to our vendors.

Investing Activities

For the six months ended June 30, 2026, we used $5.9 million in cash for investing activities, which related to $5.1 million of technology investments in intangible assets and $0.8 million in capital expenditures.

For the six months ended June 30, 2025, we used $3.1 million in cash for investing activities, which related primarily to $2.7 million of technology investments in intangible assets and $0.5 million in capital expenditures.

Financing Activities

For the six months ended June 30, 2026, we generated $253.0 million related to financing activities, driven by proceeds from our follow-on offerings of $243.9 million, net of deferred offering costs, underwriting discounts and commissions, proceeds from the exercise of stock options of $6.1 million and proceeds from the exercise of warrants of $3.0 million.

For the six months ended June 30, 2025, we generated approximately $0.2 million in financing activities, driven primarily by proceeds from the exercise of stock options.

Non-GAAP Financial Measures

We use non-GAAP net loss and non-GAAP gross profit, both non-GAAP financial measures, to help us make strategic decisions, establish budgets and operational goals for managing our business, analyze our financial results and evaluate our performance. We define non-GAAP net loss as our net loss adjusted to exclude expenses not directly attributable to the performance of our operations, such as income taxes, depreciation and amortization, stock-based compensation, gain on nonmonetary transaction, severance costs, IPO-related transaction costs, and warrant valuation. We define non-GAAP gross profit as our gross profit adjusted to exclude expenses not directly attributable to gross profit, such as depreciation and amortization, stock-based compensation and non-monetary transactions.

We present the non-GAAP financial measures non-GAAP net loss and non-GAAP gross profit in this Quarterly Report on Form 10-Q because we believe these non-GAAP financial measures provide additional tools for investors to use in comparing our core business and results of operations over multiple periods with other companies in our industry, many of which present similar non-GAAP financial measures to investors. However, our presentation of non-GAAP net loss and 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 and 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.

Some of these limitations are that non-GAAP net loss and non-GAAP gross profit:

do not reflect incomes taxes, which are necessary costs incurred in connection with our operations and reduce cash available to us;
exclude depreciation and amortization, and although these are non-cash expenses, the assets being depreciated may have to be replaced in the future, increasing our cash requirements;
do not reflect stock-based compensation expenses, which represent a significant cost of attracting and retaining qualified employees, and excluding them may underestimate the true economic cost of our workforce;
do not reflect gain on nonmonetary transactions;
do not reflect severance costs which represent costs associated with reductions in force;
exclude IPO and related transaction costs which represent non-recurring professional fees for advisory, legal, accounting, valuation and other professional or consulting services incurred related to the IPO; and
exclude warrant valuation costs, which represent the mark-to-market valuation of liability-classified warrants.

Because of these limitations, we consider, and you should consider, non-GAAP net loss and non-GAAP gross profit alongside other financial performance measures, including net loss and gross profit and our other GAAP results. A reconciliation of our non-GAAP net loss to net loss and non-GAAP gross profit to gross profit, the most directly comparable financial measures stated in accordance with GAAP, are provided below. Investors are encouraged to review the related GAAP financial measures and the reconciliation of the non-GAAP financial measure to their most directly comparable GAAP financial measure.

The following tables reconcile the most directly comparable GAAP financial measure to each of these non-GAAP financial measures.

Critical Accounting Policies and Estimates

Our discussion and analysis of financial condition are based upon the consolidated financial statements of this business, which have been prepared in accordance with GAAP. The preparation of these financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, sales and expenses and related disclosure of contingent assets and liabilities. On an on-going basis, we evaluate our estimates, including those related to bad debts, revenue reserves, inventory valuation, stock-based compensation, taxes on income, warranty obligations and contingencies and litigation. We based our estimates on

historical experience and on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates and such differences may be material to the financial statements. We believe that the accounting policies and estimates described below are the most meaningful to our operations or require management's most difficult, subjective or complex judgments. Judgments or uncertainties affecting the application of these policies may result in materially different amounts being reported under different conditions or using different assumptions. Accordingly, we believe these are the most critical to aid in fully understanding and evaluating our financial condition and results of operations. Our significant accounting policies are described in Note 1 to our unaudited condensed consolidated financial statements included in this Quarterly Report on Form 10-Q.

There have been no material changes to our critical accounting policies and estimates as described in our Annual Report on Form 10-K.

Recently Issued and Adopted Accounting Pronouncements

For more information regarding recently issued accounting pronouncements, see Note 1 to our unaudited condensed consolidated financial statements included elsewhere in this Quarterly Report on Form 10-Q.

Controls and Procedures

We are not currently required to comply with all the provisions of the Sarbanes-Oxley Act of 2002 (Sarbanes-Oxley Act). Our management is not required to certify as to the effectiveness of our internal control over financial reporting until our second annual report on Form 10-K following our IPO. Only in the event that we are deemed to be a large accelerated filer or an accelerated filer and no longer qualify as an emerging growth company will our independent registered public accounting firm be required to provide an attestation report on the effectiveness of our internal control over financial reporting. Further, for as long as we remain an emerging growth company, we intend to take advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not emerging growth companies, including, but not limited to, not being required to comply with the independent registered public accounting firm attestation requirement. However, we do have internal controls in place in key areas of risk.

Emerging Growth Company and Smaller Reporting Company Status

We are an "emerging growth company," as defined in the JOBS Act, enacted in April 2012. We intend to take advantage of certain exemptions under the JOBS Act from various public company reporting requirements, including not being required to have our internal control over financial reporting audited by our independent registered public accounting firm pursuant to Section 404(b) of the Sarbanes-Oxley Act, reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements, and exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and any golden parachute payments not previously approved. In addition, an emerging growth company can take advantage of an extended transition period for complying with new or revised accounting standards. This provision allows an emerging growth company to delay the adoption of certain accounting standards until those standards would otherwise apply to private companies. We have elected to avail ourselves of this provision of the JOBS Act. As a result, we will not be subject to new or revised accounting standards at the same time as other public companies that are not emerging growth companies. Therefore, our consolidated financial statements may not be comparable to those of companies that comply with new or revised accounting pronouncements as of public company effective dates.

We will remain an emerging growth company and may take advantage of these exemptions until the earliest of: (i) December 31, 2030; (ii) the last day of the fiscal year in which we have total annual gross revenue of at least $1.235 billion; (iii) the last day of the fiscal year in which we are deemed to be a "large accelerated filer" as defined in Rule 12b-2 under the Exchange Act, which would occur if the market value of our common stock held by non-affiliates exceeded $700.0 million as of the last business day of the second fiscal quarter of such year; or (iv) the date on which we have issued more than $1.0 billion in non-convertible debt securities during the prior three-year period.

We are also a "smaller reporting company" as defined in the Exchange Act. We may continue to be a smaller reporting company even after we are no longer an emerging growth company. We may take advantage of certain of the scaled disclosures available to smaller reporting companies and will be able to take advantage of these scaled disclosures for so long as our voting and non-voting common stock held by non-affiliates is less than $250.0 million measured on the last business day of our second fiscal quarter, or our annual revenue is less than $100.0 million during the most recently completed fiscal year and our voting and non-voting common stock held by non-affiliates is less than $700.0 million measured on the last business day of our second fiscal quarter.
