GCT Semiconductor (GCTS) posts $1.9M Q1 2026 revenue amid losses and high debt
GCT Semiconductor Holding, Inc. reported net revenues of $1.9 million for the three months ended March 31, 2026, up sharply from $0.5 million a year earlier, driven by higher product and service revenue. Gross profit improved to $0.9 million, but the company still posted a net loss of $9.9 million, similar on a per‑share basis at $(0.15). Cash and cash equivalents rose to $7.2 million, mainly from financing activities, including $12.7 million of common stock sales under an at‑the‑market program and $2.8 million from Indigo convertible notes. Total liabilities were $96.3 million, with $52.7 million of borrowings and $5.0 million of convertible notes outstanding, leaving a stockholders’ deficit of $73.9 million and an accumulated deficit of $615.3 million. Management disclosed that recurring losses, negative operating cash flows, heavy near‑term debt maturities and dependence on additional fundraising raise substantial doubt about the company’s ability to continue as a going concern beyond twelve months.
Positive
- None.
Negative
- Substantial doubt about going concern: Recurring losses, negative operating cash flows, heavy near‑term debt maturities and dependence on additional financing led management to conclude there is substantial doubt about the company’s ability to continue as a going concern beyond twelve months.
Insights
Losses, heavy short-term debt and reliance on dilutive funding create elevated financial risk.
GCT increased Q1 2026 revenue to $1.9 million, but still generated a net loss of $9.9 million and used $7.4 million of cash in operating activities. The business is not yet self‑funding and depends on external capital.
Total liabilities reached $96.3 million, including $52.7 million of borrowings and $5.0 million of convertible notes, against cash of $7.2 million. Most debt is short term, with $49.1 million of principal due in the remainder of 2026, plus related‑party loans incurring 3% monthly penalty rates.
The company raised equity via a $75.0 million at‑the‑market program, selling $12.7 million in Q1 2026, and has up to $20.0 million each available under Indigo and Obsidian convertible note facilities. Management explicitly states that these conditions create substantial doubt about going concern; subsequent filings will be important to see if additional capital is secured and debt terms are extended.

Special Note Regarding Forward-Looking Statements
This Quarterly Report on Form 10‑Q (“Quarterly Report”) contains forward-looking statements within the meaning of the safe harbor provisions of the Private Securities Litigation Reform Act of 1995, including statements about our financial condition, results of operations, earnings outlook and our prospects. In addition, any statements that refer to projections, forecasts or other characterizations of future events or circumstances, including any underlying assumptions, are forward-looking statements. Forward-looking statements are typically identified by words such as “plan,” “believe,” “expect,” “anticipate,” “intend,” “outlook,” “estimate,” “forecast,” “project,” “continue,” “could,” “may,” “might,” “possible,” “potential,” “predict,” “should,” “would” and other similar words and expressions, but the absence of these words does not mean that a statement is not forward-looking.
The forward-looking statements are based on the current expectations of our management and are inherently subject to uncertainties and changes in circumstances and their potential effects and speak only as of the date of such statement. These forward-looking statements involve a number of risks, uncertainties or other assumptions that may cause actual results or performance to be materially different from those expressed or implied by these forward-looking statements. These risks and uncertainties include, but are not limited to, the following:
i
Table of Contents
A detailed discussion of risks and uncertainties that could cause actual results and events to differ materially from such forward-looking statements is included in the section entitled “Risk Factors” contained in our Annual Report on Form 10‑K filed with the U.S. Securities and Exchange Commission (“SEC”) on March 25, 2026. These forward-looking statements are based on information available as of the date of this Quarterly Report, and current expectations, forecasts and assumptions, and involve a number of judgments, risks and uncertainties. New risk factors emerge from time to time, and it is not possible for us to predict all such risk factors, nor can we assess the impact of all such risk factors on our business or the extent to which any factor or combination of factors may cause actual results to differ materially from those contained in any forward-looking statements. All forward-looking statements attributable to us or persons acting on our behalf are expressly qualified in their entirety by the foregoing cautionary statements. We undertake no obligations to update or revise publicly any forward-looking statements, whether as a result of new information, future events or otherwise, except as required by law.

Notes to Unaudited Condensed Consolidated Financial Statements
1. Organization and Liquidity
Description of Business
GCT Semiconductor Holding, Inc. and its wholly owned subsidiaries (collectively “GCT” or the “Company”) is headquartered in San Jose, California, with international offices in South Korea, China, Taiwan, and Japan. The Company is a fabless semiconductor company that specializes in the design, manufacturing, and sale of communication semiconductors, including high-speed wireless communication technologies such as 5G/4.75G/4.5G/4G transceivers and modems, which are essential for a wide variety of industrial, business-to-business (“B2B”) and consumer applications.
Liquidity
The accompanying unaudited condensed consolidated financial statements have been prepared assuming the Company will continue as a going concern, which contemplates the realization of assets, liabilities, and commitments in the normal course of business. Through March 31, 2026, the Company has incurred operating losses and negative cash flows from operating activities and had an accumulated deficit of $
In April 2025, the Company executed an at-market issuance sales agreement (“ATM Agreement”) with B. Riley Securities, Inc. and H.C. Wainwright & Co., LLC, acting as sales agents. The ATM Agreement allows the Company to sell its common stock for gross proceeds of up to $
In December 2025, the Company entered into a convertible promissory note purchase agreement with Indigo Capital LP (“Indigo”), which provides for the issuance of convertible promissory notes of up to $
In March 2026, the Company entered into a convertible promissory note purchase agreement with Obsidian Global GP, LLC (“Obsidian”), which provides for the issuance of convertible promissory notes of up to $
To fund its operations over the longer term, the Company will need to start generating positive cash flows, renegotiate its existing debt obligations, and raise additional capital through debt or equity financing. Management’s plans include seeking additional financing, such as issuances of equity, issuances of debt and convertible debt instruments. Sales of additional equity securities, convertible debt, or warrants by the Company could dilute the interests of existing stockholders. The Company will require significant additional financing to meet its planned capital needs and is pursuing opportunities to obtain additional financing through equity or debt alternatives. There can be no assurance that such additional debt or equity financing will be available on terms acceptable to the Company or at all. These factors raise substantial doubt about the Company’s ability to continue as a going concern beyond twelve months after the date that these unaudited condensed consolidated financial statements are issued. The accompanying unaudited condensed consolidated financial statements do not include any adjustments that might be necessary if the Company is unable to continue as a going concern.
2. Summary of Significant Accounting Policies and Basis of Presentation
Principles of Consolidation and Basis of Presentation
The unaudited condensed consolidated financial statements and accompanying notes include the accounts of the Company and its wholly owned subsidiaries, after elimination of intercompany balances and transactions. The accompanying unaudited condensed consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and the requirements of the Securities and Exchange Commission (“SEC”) for interim financial information. Certain information and disclosures normally included in annual consolidated financial statements prepared in accordance with U.S. GAAP have been condensed or omitted. Accordingly, these interim unaudited condensed consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements and notes thereto for the year ended December 31, 2025, which are included in the Company’s Form 10‑K filed with the SEC on March 25, 2026.
The information as of December 31, 2025 included in the unaudited condensed consolidated balance sheets was derived from the audited consolidated financial statements.

Table of Contents
GCT SEMICONDUCTOR HOLDING, INC.
Notes to Unaudited Condensed Consolidated Financial Statements
The unaudited condensed consolidated financial statements have been prepared on the same basis as the annual consolidated financial statements and, in the opinion of management, reflect all adjustments, which include only normal recurring adjustments necessary for the fair presentation of the Company’s financial information. The unaudited condensed consolidated results of operations for the three months ended March 31, 2026 are not necessarily indicative of the results to be expected for the year ending December 31, 2026 or for any other future annual or interim period.
There have been no material changes in the Company’s significant accounting policies as compared to the significant accounting policies described in the Company’s Annual Report on Form 10-K for the year ended December 31, 2025.
Use of Estimates
The preparation of the accompanying unaudited condensed consolidated financial statements in conformity with U.S. GAAP requires management to make judgments, estimates, and assumptions about future events. These estimates and the underlying assumptions affect the amounts of assets and liabilities reported, disclosures about contingent assets and liabilities, and reported amounts of revenues and expenses. These judgments, estimates, and assumptions are used for but not limited to revenue recognition, provision for credit losses, deferred income taxes and related valuation allowances, inventory obsolescence, recoverability of long-lived assets, certain accrued expenses, stock-based compensation, determination of the fair value of the Company’s financial instruments, including convertible promissory notes, warrant liabilities, stock options, and common stock forward liability. The Company bases its estimates and judgments on historical experience and on various other assumptions that it believes are reasonable under the circumstances. Actual results could differ from these estimates, and these differences may be material.
Risk and Uncertainties
The Company is subject to certain risks and uncertainties and believes changes in any of the following areas could have a material adverse effect on the Company’s future financial position or results of operations or cash flows: 5G and other new product development, including market receptivity, the ability to satisfy obligations under development agreements with major partners, litigation or claims against the Company based on intellectual property, patent, product regulation or other factors, competition from other products, general economic conditions, the ability to attract and retain qualified employees and ultimately to sustain profitable operations.
The semiconductor industry is characterized by rapid technological change, competition, competitive pricing pressures, and cyclical market patterns. The Company’s financial results are affected by a wide variety of factors, such as general economic conditions specific to the semiconductor industry and the Company’s particular market, the timely implementation of new 5G and other new products, new manufacturing process technologies, and the ability to safeguard patents and intellectual property in a rapidly evolving market. In addition, the semiconductor market has historically been cyclical and subject to significant economic downturns. As a result, the Company may experience significant period-to-period fluctuations in the unaudited condensed consolidated operating results due to these factors.
The Company’s revenue may be impacted by its ability to obtain adequate wafer supplies from foundries and back-end production capacity from the Company’s test and assembly subcontractors. The foundries with which the Company currently has arrangements may not be willing or able to satisfy all of the Company’s manufacturing requirements on a timely basis or at favorable prices. The Company is also subject to the risks of service disruptions, raw material shortages, and price increases by its foundries. Such disruptions, shortages, and price increases could harm the Company’s consolidated operating results.
Provision for Credit Losses
The provision for credit losses is based on the Company’s assessment of the collectibility of its customer accounts. The Company reviews the provision for credit losses by considering certain factors such as historical experience, industry data, credit quality, age of balances, and current economic conditions that may affect a customer’s ability to pay. Uncollectible receivables are written off when all efforts to collect have been exhausted, and recoveries are recognized when they are recovered. The Company had a provision for credit losses of approximately $
Revenue Recognition
The Company’s revenues are generated by the sale of 4G and 5G mobile semiconductor solutions consisting of product and platform solutions aimed at the 4G LTE and 5G NR (New Radio) wireless communications industry, and related development services and technical advice and maintenance services. To determine when revenues are recognized, the Company performs the following five steps: (1) identify the contract(s) with a customer, (2) identify the performance obligation in the contract, (3) determine the transaction price,
7
Table of Contents
GCT SEMICONDUCTOR HOLDING, INC.
Notes to Unaudited Condensed Consolidated Financial Statements
(4) allocate the transaction price to the performance obligations in the contract, and (5) recognize revenue when or as the Company satisfies a performance obligation.
The revenues from product sales are identified and determined pursuant to purchase orders. The Company considers a performance obligation satisfied once it has transferred control of a good or product to a customer, meaning the customer has the ability to direct the use and obtain the benefit of the product, which is generally at the time of shipment.
Service revenues are identified and determined based on each service agreement and recognized over time or at a point in time, depending on the evaluation of when the customer obtains control of the promised goods or services, which is generally as services are rendered. Service revenue may include licensing fees, which are recognized upon delivery of the license, generally at a point in time. For contracts that include multiple performance obligations, the Company allocates revenue to each performance obligation based on estimates of the relative stand-alone selling price that the Company would charge the customer for each promised product or service.
All product revenue presented in the unaudited condensed consolidated statements of operations is recognized at a point in time, and all service revenue is recognized over time.
Concentration of Credit Risk
The Company’s financial instruments subject to credit risk concentration consist of cash and cash equivalents and accounts receivable. The Company maintains its cash and cash equivalents primarily with one financial institution located in the United States and another located in South Korea, where amounts deposited may exceed Federal Deposit Insurance Corporation or Korea Deposit Insurance Corporation limits. The Company’s accounts receivable balances are primarily derived from revenues recognized from customers located in the United States, China, South Korea, Japan, and Taiwan. The Company performs ongoing credit evaluations of the financial condition of its customers and distributors and generally does not require collateral.

Management closely monitors the creditworthiness and performance of these key customers and has established credit limits and terms to mitigate potential credit risks. The Company also continues to diversify its customer base and explore opportunities to reduce its reliance on a few major customers.
Foreign Currency
Financial statements of foreign subsidiaries that use the local currency as their functional currency are translated into U.S. dollars at the end-of-period exchange rates or at historical exchange rates for purposes of consolidation. Revenues and expenses are translated using average exchange rates during the reporting period. Translation adjustments are included in accumulated other comprehensive income or loss within stockholders’ deficit.
Gains and losses resulting from transactions denominated in a currency other than the functional currency are presented separately in the unaudited condensed consolidated statements of operations. For the three months ended March 31, 2026, the Company recognized realized foreign currency exchange gains of $
Convertible Promissory Notes
The Company has elected the fair value option to account for its outstanding convertible promissory notes, with changes in estimated fair value presented separately under the corresponding caption in the unaudited condensed consolidated statements of operations. The Company has made this election as the fair value option better reflects the underlying economics within convertible promissory notes. Through March 31, 2026, there were no changes in the instrument-specific credit risk that are required to be presented as a component of accumulated other comprehensive income.
Accumulated Other Comprehensive Income (Loss)
Accumulated other comprehensive income (loss) includes all changes within equity that are not the result of transactions with stockholders. Accumulated other comprehensive income (loss) includes foreign currency translation adjustments arising from the consolidation of the Company’s foreign subsidiaries.
Common Stock Warrants
Common stock warrants are classified as liabilities if they do not meet equity classification requirements based on their settlement mechanism upon a change of control and similar transactions. The corresponding liability is remeasured at fair value while the common stock warrants remain outstanding, with changes in fair value presented separately in the unaudited condensed consolidated statements

of operations. Common stock warrants that meet equity classification requirements are credited to stockholders’ deficit on their issuance dates and are not subsequently remeasured.
Segment Information
The Company operates in
Emerging Growth Company Status
The Company is an emerging growth company (“EGC”), as defined in the Jumpstart Our Business Startups Act of 2012 (the “JOBS” Act). Under the JOBS Act, EGCs can delay adopting new or revised accounting standards using private company timelines. The Company has elected to use this extended transition period for complying with new or revised accounting standards that have different effective dates for public and private companies until the earlier of the date that it (i) is no longer an emerging growth company or (ii) affirmatively and irrevocably opts out of the extended transition period provided in the JOBS Act. As a result, these unaudited condensed consolidated financial statements may not be comparable to companies that comply with the new or revised accounting pronouncements as of public company effective dates. The Company anticipates that its EGC status will expire in November 2026 based on the five-year anniversary of the initial public offering of Concord Acquisition Corp III, its predecessor reporting entity.
Recent Accounting Pronouncements Adopted
In July 2025, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2025-05, Measurement of Credit Losses for Accounts Receivable and Contract Assets (“ASU 2025-05”), which introduces a practical expedient allowing entities to assume that current conditions as of the balance sheet date remain unchanged over the remaining life of the asset when estimating expected credit losses for current accounts receivable and current contract assets within the scope of “Revenue from Contracts with Customers (Topic 606)”. ASU 2025‑05 is effective for annual periods beginning after December 15, 2025, and interim periods within those annual reporting periods, with early adoption permitted. The Company
Recent Accounting Pronouncements Not Yet Adopted
In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures (“ASU 2023-09”), which requires companies to disclose, on an annual basis, specific categories in the effective tax rate reconciliation and provide additional information for reconciling items that meet a quantitative threshold. In addition, companies are required to disclose additional information about income taxes paid. ASU 2023-09 is effective for the Company as an emerging growth filer for annual periods beginning after December 15, 2025, with early adoption permitted. The standard is required to be adopted on a prospective basis; however, retrospective application is permitted. The Company is currently evaluating the impact of the adoption of ASU 2023-09 on its consolidated financial statements and related disclosures.
In November 2024, the FASB issued ASU 2024-03, Income Statement - Reporting Comprehensive Income (Topic 220): Disaggregation of Income Statement Expenses (“ASU 2024-03”), which requires public entities to provide disaggregated disclosures of certain expense captions presented on the face of the income statement into specific categories within the notes to the consolidated financial statements. ASU 2024-03 is effective for the Company’s annual periods beginning after December 15, 2026, and interim periods within fiscal years beginning after December 15, 2027, with early adoption permitted. The ASU may be applied either on a prospective or retrospective basis. The Company is currently evaluating the impact of the adoption of ASU 2024-03 on its consolidated financial statements and related disclosures.
In September 2025, the FASB issued ASU 2025-07, Derivatives and Hedging (Topic 815) and Revenue from Contracts with Customers (Topic 606) (“ASU 2025-07”). The guidance refines the scope of Topic 815 to clarify which contracts are subject to derivative accounting. The guidance also provides clarification under Topic 606 for share-based noncash consideration from a customer in a revenue contract. The amendments in ASU 2025-07 are effective for fiscal years beginning after December 15, 2026, and interim

reporting periods, with early adoption permitted. The Company is currently evaluating the impact of the adoption of ASU 2025-07 on its consolidated financial statements and related disclosures.
In December 2025, the FASB issued ASU 2025-11, Interim Reporting (Topic 270) Narrow-Scope Improvements (“ASU 2025-11”). The amendments in this update clarify interim disclosure requirements and the applicability of Topic 270. The objective of the update is to provide clarity about current interim requirements. The amendments in this update also include a disclosure principle that requires entities to disclose events since the end of the last annual reporting period that have a material impact on the entity. The amendments in ASU 2025-11 are effective for interim periods within annual reporting periods beginning after December 15, 2027, with early adoption permitted. The Company is currently evaluating the impact of the adoption of ASU 2025-11 on its future interim consolidated financial statements and related disclosures.
In December 2025, the FASB issued ASU 2025-12, Codification Improvements (“ASU 2025-12”). ASU 2025-12 addresses suggestions received from stakeholders regarding the Accounting Standards Codification (“ASC”) and makes other incremental improvements to U.S. GAAP. The update represents changes to the Codification that clarify, correct errors in or make other improvements to a variety of topics that are intended to make it easier to understand and apply. ASU 2025-12 is effective for fiscal years beginning after December 15, 2026 and interim periods within those fiscal years. The amendments to ASC 260, Earnings Per Share, must be applied retrospectively, while all other amendments may be applied prospectively or retrospectively. Early adoption is permitted. The Company is currently evaluating the impact of the adoption of ASU 2025-12 on its consolidated financial statements and related disclosures.

7. Commitments and Contingencies
Litigation
The Company is subject to various claims arising in the ordinary course of business. Although no assurance can be given, the Company believes that it is not a party to any litigation of which the outcome, if determined adversely, would individually, or in the aggregate, be reasonably expected to have a material adverse effect on the business, consolidated operating results, cash flows or financial position of the Company as of March 31, 2026.
Third parties have from time to time claimed, and others may claim in the future, that the Company has infringed their past, current or future intellectual property rights. These claims, whether meritorious or not, could be time-consuming, result in costly litigation, require expensive changes in the Company’s methods of doing business or could require the Company to enter into costly royalty or licensing agreements, if available. As a result, these claims could harm the Company’s business, consolidated operating results, cash flows, and financial position.
Purchase Commitments
The Company has certain commitments for outstanding purchase orders related to the manufacture of certain wafers utilized by the Company and other services that, once the wafers are placed into production, are noncancellable. Otherwise, these production agreements are cancellable at any time, with the Company required to pay all costs incurred through the cancellation date. However, the Company does not have a history of cancelling these agreements once production has started. As of March 31, 2026, the Company had outstanding noncancellable purchase commitments for these production agreements of $

B. Riley Purchase Agreement
In April 2024, the Company executed a common stock purchase agreement (“Purchase Agreement”) with B. Riley Principal Capital II, LLC (“B. Riley”). Pursuant to the Purchase Agreement, the Company has the right, but not the obligation, to sell to B. Riley, from time to time, up to $
The Purchase Agreement was determined to be an equity-linked contract that contains a purchased put option on the Company’s common stock and variable share forward. These freestanding instruments are precluded from equity classification since the Purchase Agreement requires shareholder approval for the issuance of shares in excess of the applicable ownership limitation caps, which is not an input in a fixed-for-fixed option or forward on equity shares.
As of April 2024, the Company determined that the fair value of the put option was nominal due to the short settlement period of one

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations.
This discussion and analysis of our financial condition and results of operations should be read together with our unaudited condensed consolidated financial statements as of and for the three months ended March 31, 2026 and related notes appearing elsewhere in this quarterly report on Form 10-Q (“Quarterly Report”) and our audited consolidated financial statements as of and for the years ended December 31, 2025 and 2024 and related notes included in our Form 10‑K (“Annual Report”) filing with the Securities and Exchange Commission (“SEC”) on March 25, 2026.
This discussion may contain forward-looking statements including, but not limited to, our expectations or predictions of future financial or business performance or conditions. Forward-looking statements are inherently subject to risks, uncertainties, and assumptions. You should read the sections in this Quarterly Report titled “Risk Factors” and “Special Note of Forward-Looking Statements” for a discussion of important factors that could cause actual results to differ materially from the results described in or implied by these forward-looking statements. Unless otherwise indicated, the terms “GCT,” “the Company,” “we,” “us,” or “our” refer to GCT Semiconductor Holding Inc., a Delaware corporation, together with our consolidated subsidiaries.
Overview
We are a fabless semiconductor company that specializes in the design, manufacturing, and sale of communication semiconductors, including high-speed wireless communication technologies such as 5G/4.75G/4.5G/4G transceivers (“RF”) and modems, which are essential for a wide variety of industrial, business-to-business (“B2B”) and consumer applications. We have successfully developed and supplied communication semiconductor chipsets and modules to leading wireless operators worldwide, as well as to original design manufacturers (“ODMs”) and original equipment manufacturers (“OEMs”) for portable wireless routers (e.g., Mobile Router (“MiFi”)), indoor and outdoor fixed wireless routers (e.g., customer premise equipment (“CPE”)), industrial machine-to-machine (“M2M”) applications and smartphones.
We oversee sales, marketing, and accounting operations from our headquarters in San Jose, California. The Company conducts product design, development, and customer support through our wholly owned subsidiaries located in South Korea, one of which serves as our research and development center. In addition, we utilize separate sales offices for local technical support and sales in Taiwan, China, and Japan.
Our current product portfolio includes RF and modem chipsets based on 4th generation (“4G”), known as Long Term Evolution (“LTE”), technology offering a variety of chipsets differentiated by speed and functionality. These include 4G LTE, 4.5G LTE Advanced (twice the speed of LTE), and 4.75G LTE Advanced-Pro (four times the speed of LTE) chipsets. The Company also develops and sells cellular Internet of Things (“IoT”) chipsets for low-speed mobile networks such as eMTC/NB-IOT/Sigfox, and other network protocols. 5G chipset added to our portfolio recently, with commercial shipments in the fourth fiscal quarter of 2025.
Even as more and more applications are deployed on 5G networks, we believe that demand for our existing 4G LTE product lineup (4.75G/4.5G/4G, etc.) will continue, because 4G products are expected to coexist in the market with 5G products at lower price points for some time in the same way that 3rd generation (“3G”) products coexisted with 4G products when 4G networks were first deployed. We commenced our first production shipments of our 5G products in the last quarter of 2025. Also, we expect the average sales prices for our 5G chipset to be approximately four times that of our 4G chipset, resulting in a significant increase in revenue and gross margins. We plan to continuously expand our product lineup to support 5G chipsets for future applications such as vehicle-to-everything standard (e.g., C-V2X), 5G-based satellite communication (e.g., Non-Terrestrial Network), and 5G-based IoT standard (e.g., RedCap). Our current chipset products are used in a wide variety of applications, including fixed wireless subscriber terminals (e.g., CPE), mobile wireless routers (e.g., Mobile Router/MiFi), various communication modules and devices, and industrial products.
Since inception, we have financed our operations primarily through cash receipts from customers, the issuance of convertible promissory notes, borrowings, and the issuance of capital stock.
Key Factors Affecting Our Performance
We believe that our future success and financial performance depend on a number of factors that present significant opportunities for our business but also pose risks and challenges, including those described in the section titled “Risk Factors” of our Annual Report on Form 10-K filed with the SEC on March 25, 2026.

Table of Contents
Commercial Deployment of 4G LTE and 5G Market
Our business depends upon the continued commercial deployment of 4G and 5G wireless communications equipment, products, and services based on GCT’s technology. Deployment of new networks by wireless carriers requires significant capital expenditures well in advance of any revenue from such networks. If the rate of deployment of new networks by wireless carriers is slower than our expectation, this will reduce the sales of products for use on these networks by OEMs and ODMs that use GCT technology. This would harm our revenues and our financial results. The worldwide commercial deployment and adoption of the narrow band LTE variants, Cat M and Cat NB, are expected to further expand the markets for IoT devices. If deployments of the Cat M or Cat NB standards are delayed or if competing standards for IoT devices become favored by wireless carriers, we may not be able to successfully increase sales of our Cat M and Cat NB products, which would harm our revenues and financial results. 5G RedCap and eRedCap appear to be of great interest to wireless carriers, although adoption is limited at this early stage. If an alternative were to appear in the short-to-mid-term this could result in reduced long-term demand for our RedCap and eRedCap chipsets. It should also be noted that RedCap and eRedCap is expected to be a replacement for CatM, Cat1bis and some Cat4 thus eventually reducing demand for the LTE IoT chipsets.
Development of New Products
The markets in which we and our customers compete or plan to compete are characterized by rapidly changing technologies, industry standards, and technological obsolescence. Our ability to compete successfully depends on our ability to design, develop, market, and support new products and enhancements on a timely and cost-effective basis. A fundamental shift in technologies in any of our target markets, such as the 5G wireless communications markets, could harm our competitive position within these markets. Our failure to anticipate these shifts, develop new technologies, or react to changes in existing technologies could delay our development of new products, which could result in product obsolescence, decreased revenue, and loss of design wins.
The success of our new products will depend on accurate forecasts of long-term market demand, customer and consumer requirements, and future technological developments, as well as a variety of specific implementation factors, including:
If we fail to introduce new products that meet the demands of our customers or our target markets, or if we fail to penetrate new markets, our revenue will likely decrease over time, and our financial condition could suffer.
Semiconductor and Communications Industry
The semiconductor industry has historically exhibited a pattern of cyclicality, which at various times has included significant downturns in customer demand. Cyclical downturns can result in substantial declines in semiconductor demand, production overcapacity, high inventory levels, and accelerated erosion of average selling prices. Such downturns result from a variety of market forces, including constant and rapid technological change, quick product obsolescence, price erosion, evolving standards, short product life cycles, and wide fluctuations in product supply and demand.
Recent downturns in the semiconductor industry have been attributed to a variety of factors, including global macroeconomic uncertainty, trade and geopolitical tensions including tariffs, weakness in end-market demand and pricing across semiconductor applications. In recent periods, portions of the semiconductor industry have experienced downturns driven by inventory corrections and reduced demand in certain end markets, while other segments have experienced increased investment and growth. These mixed industry conditions have impacted our business, as well as our suppliers, distributors, and end customers.
Because a significant portion of our expenses are fixed in the near term or are incurred in advance of anticipated sales, we may not be able to reduce our expenses rapidly enough to offset any unanticipated shortfall in revenue. If this situation were to occur, it could adversely affect our operating results, cash flow, and financial condition. In addition, the semiconductor industry has periodically

experienced increased demand and production constraints. As a fabless semiconductor company, we rely exclusively on third-party foundries, including certain major semiconductor foundries such as United Microelectronics Corporation, Samsung and Taiwan Semiconductor Manufacturing Corporation, for the manufacturing and supplies of its wafers and products. We do not have any formal foundry agreements that guarantee a minimum level of manufacturing capacity. In times of significant increasing demand for capacity, these foundries may experience production shortages and may not allocate sufficient manufacturing capacity to us. If this happens, we may not be able to produce sufficient quantities of our products to meet the increased demand. Any disruption in our supply chain can make it more difficult for us to obtain sufficient wafer, assembly, and test resources from our subcontract manufacturers. Any factor adversely affecting the semiconductor industry in general, or the particular segments of the industry that our products target, may adversely affect our ability to generate revenue and impact our operating results.
In addition, a shortage of manufacturing capacity can also impact the product development strategies of our major customers, which may, in turn, affect our business operations. For example, in 2022, the supply shortage caused our largest customer to change its priority on product development from 4G to the next generation of 5G products (at a time when our 5G product was not available), which resulted in the reduction of 4G activity and a decline in demand for our products.
In the past, the wireless communications industry has experienced pronounced downturns, and these cycles may continue in the future. A future decline in global economic conditions could have adverse, wide-ranging effects on demand for our products and for the products of our customers, particularly wireless communications equipment manufacturers or other members of the wireless industry, such as wireless network operators. Inflation, deflation, and economic recessions that adversely affect the global economy and capital markets also adversely affect our customers and our end consumers. For example, our customers’ ability to purchase or pay for our products and services, obtain financing, and upgrade wireless networks could be adversely affected, which may lead to many networking equipment providers slowing their research and development activities, canceling, or delaying new product development, reducing their inventories, and taking a cautious approach to acquiring our products, which would have a significant negative impact on our business. If this situation were to occur, it could adversely affect our operating results, cash flow, and financial condition. In the future, any of these trends may also cause our operating results to fluctuate significantly from year to year, which may increase the volatility of our stock price.
Key Components of Results of Operations
Net Revenues
The timing of revenue recognition and the amount of revenue recognized in each case depends on various factors, including the specific terms of each arrangement and the nature of the underlying performance obligations. Our net revenues are comprised of product and service revenues.
Product Revenues
Our product sales are generated from the sale of mobile semiconductor products. Product revenues are recognized at a point in time once control has been transferred to a customer, which is generally at the time of shipment.
Service Revenues
Our service revenues are generated from the sale of mobile semiconductor platform solutions aimed at the 4G LTE and 5G industries, development services, technical advice, and maintenance services. Service revenues are generally recognized over time as the customer obtains control of the promised services. Service revenue may include licensing fees, which are recognized upon delivery of the license, generally at a point in time.
Cost of Net Revenues
Our cost of net revenues consists of product and service costs. The cost of product net revenues consists of direct and indirect costs related to the manufacturing of our products. Direct costs include wafer costs and costs of assembly and testing performed by third-party contract manufacturers. Indirect costs consist of provisions for excess, slow moving and obsolete inventory, royalties, allocated overhead for employee costs and facility costs, warranty, and the amortization of our production mask sets and certain intangible assets. Shipping and handling costs incurred for inventory purchases related to the units sold and costs of product shipments are also recorded in the cost of net product revenues. Service costs consist of non-recurring engineering costs for service projects.

Operating Expenses
Research and Development Expenses
Our research and development (“R&D”) expenses consist of costs incurred to develop our products and services. These expenses consist of personnel costs, including salaries, employee benefit costs, and stock-based compensation for employees engaged in R&D activities, software costs, computing costs, hardware and experimental supplies, and expenses for outside engineering consultants. We expense all R&D costs in the periods in which they are incurred.
Sales and Marketing Expenses
Our sales and marketing (“S&M”) expenses consist of employee-related expenses, including salaries, commissions, employee benefits costs, and stock-based compensation for all marketing, sales, and sales support employees. S&M expenses also include local and centralized advertising costs and the infrastructure required to support our marketing efforts. We expense S&M costs in the periods in which they are incurred.
General and Administrative Expenses
Our general and administrative (“G&A”) expenses consist of various components not related to R&D or S&M, such as personnel costs, regulatory fees, costs associated with maintaining and filing intellectual property, meals and entertainment expenses, travel expenses, insurance expenses, and other expenditures related to external professional services including legal, engineering, marketing, human resources, audit, and accounting services. Personnel costs include salaries, benefits, and stock-based compensation. As we continue to grow and expand our workforce and operations, and considering the increased costs associated with operating as a public company, we anticipate that our G&A expenses will increase for the foreseeable future.
Other Income (Expense)
Interest Expense
Interest expense primarily consists of interest and amortization of related debt issuance costs related to our borrowings and penalties incurred on our borrowings that are past their maturity dates.
Gain (loss) on foreign currency transactions, net
Gain (loss) on foreign currency transactions consists of gains or losses, presented on a net basis, from transactions denominated in other currencies, primarily South Korean won.
Change in fair value of common stock warrant liabilities
Common stock warrants are classified as liabilities if they do not meet equity classification requirements based on their settlement mechanism upon a change of control and similar transactions. The corresponding liability is remeasured at fair value while the common stock warrants remain outstanding.
Change in fair value of convertible promissory notes
Change in fair value of convertible promissory notes includes measurement gains and losses related to the outstanding convertible promissory notes that are accounted for under the fair value option.

Net Revenues
Net revenues increased by $1.4 million, from $0.5 million for the three months ended March 31, 2025 to $1.9 million for the three months ended March 31, 2026. This change was due to an increase of $0.4 million in product sales and $1.0 million in service revenues.
Product sales increased by $0.4 million, from $0.1 million for the three months ended March 31, 2025 to $0.5 million for the three months ended March 31, 2026. The sales of our LTE platforms increased by $0.3 million dollars for the three months ended March 31, 2026 compared to the three months ended March 31, 2025. Additionally, the sales of our 5G platforms contributed $0.1 million to our product sales during the three months ended March 31, 2026, and there were no 5G platform sales during the three months ended March 31, 2025.
Service revenues increased by $1.0 million, from $0.4 million for the three months ended March 31, 2025 to $1.4 million for the three months ended March 31, 2026. The increase was due to the addition of 5G revenue during the three months ended March 31, 2026, which contributed $1.4 million to our service revenue, and there was no 5G service revenue during the three months ended March 31, 2025. This increase was partially offset by a $0.4 million decrease in LTE service revenue as our service project portfolio shifted to 5G service offerings.

Cost of Net Revenues
Cost of net revenues increased by $0.6 million, from $0.4 million for the three months ended March 31, 2025 to $1.0 million for the three months ended March 31, 2026. This increase was primarily driven by higher direct costs resulting from increased unit volume.
Product costs increased by $0.7 million, from $0.2 million for the three months ended March 31, 2025 to $0.9 million for the three months ended March 31, 2026. The increase was primarily attributable to $0.4 million in higher platform costs for LTE and 5G products, to support increased sales volumes. Additionally, production overhead and depreciation charges increased by $0.2 million each during the three months ended March 31, 2025, which was primarily related to 5G equipment and overheads.
Changes in service costs were nominal.
Our gross margin increased to 49% for the three months ended March 31, 2026 from 18% for the three months ended March 31, 2025 primarily due to changes in the revenue mix. Specifically, we generated higher margins from our service offerings and increased the share of 5G and LTE platform sales during the first fiscal quarter of 2026.
Research and Development Expenses
Research and development expenses decreased by $0.9 million, from $4.1 million for the three months ended March 31, 2025 to $3.2 million for the three months ended March 31, 2026. This decrease was primarily driven by a $0.5 million reduction in project-specific intellectual property expenses incurred in the first fiscal quarter of 2026 and a $0.4 million reduction in professional services provided by Alpha for the design of 5G chip products after the completion of this development project in the second quarter of 2025.
Sales and Marketing Expenses
Sales and marketing expenses remained consistent at $1.2 million and $1.1 million for the three months ended March 31, 2026 and 2025, respectively.
General and Administrative Expenses
General and administrative expenses remained consistent at $2.7 million and $2.6 million for the three months ended March 31, 2026 and 2025, respectively.
Interest Expense
Interest expense increased by $0.7 million, from $1.1 million for the three months ended March 31, 2025 to $1.8 million for the three months ended March 31, 2026. This increase was primarily due to the penalties incurred on our outstanding loans that are past their maturity dates.
Gain on Foreign Currency Transactions, net
Foreign currency transactions resulted in a gain of $2.6 million for the three months ended March 31, 2026 and a nominal gain for the three months ended March 31, 2025. The primary factor behind these fluctuations is our term loans portfolio, which is largely denominated in the South Korean won. The gain in the first quarter of 2026 was driven by higher appreciation of the U.S. dollar against the South Korean won compared to the first quarter of 2025.
Change in Fair Value of Common Stock Warrant Liabilities
The change in fair value of common stock warrant liabilities resulted in a loss of $3.1 million for the three months ended March 31, 2026 and a gain of $1.6 million for the three months ended March 31, 2025. The loss in the first quarter of 2026 was driven by a $1.4 million loss from private warrants due to increased volatility, and a $1.7 million loss from public warrants resulting from an increase in their quoted market price. The gain in the first quarter of fiscal 2025 was primarily driven by changes in the fair value of our common stock during the three months ended March 31, 2025.
Change in Fair Value of Convertible Promissory Notes
Losses from changes in fair value of convertible promissory notes were $1.3 million and nominal for the three months ended March 31, 2026 and 2025, respectively. This increase in expense in the first fiscal quarter of 2026 reflected the fair value adjustment of the notes and the associated discount at the time of settlement of common stock.

Liquidity and Capital Resources
Since inception, we have financed our operations primarily through cash receipts from customers, the issuance of convertible promissory notes, borrowings, the issuance of capital stock, and the exercise of stock options.
With limited exceptions, we have incurred, and expect to continue to incur, significant operating losses. For the three months ended March 31, 2026, we had a net loss of $9.9 million. For the three months ended March 31, 2026, we used $7.4 million in cash in operating activities. As of March 31, 2026, we had an accumulated deficit of $615.3 million. Our unaudited condensed consolidated financial statements do not include any adjustments to reflect the possible future effects on the recoverability and classification of assets, or on the amounts and classification of liabilities, that might be necessary if we are unable to obtain adequate financing in the future. We undertake various activities to finance our operations, as further discussed below.
B. Riley Purchase Agreement
In April 2024, we entered into the Purchase Agreement and a related registration rights agreement (the “Registration Rights Agreement”) with B. Riley for an equity line of credit facility (“ELOC”). Pursuant to the ELOC, we have the right but not the obligation, to sell, from time to time, to B. Riley up to $50.0 million in aggregate gross purchase price of shares of our common stock in our sole discretion, subject to certain conditions and limitations, during the term of 24 months. Through March 31, 2026, we sold an aggregate of 2,438,737 shares of our common stock for $9.9 million under the ELOC and received cash proceeds of $8.7 million, after B. Riley withheld $1.0 million against the outstanding amounts payable. We have not sold any shares since April 2025.
At-Market Offering
In April 2025, we executed an at-market issuance sales agreement (“ATM Agreement”) with B. Riley and H.C. Wainwright & Co., LLC, acting as sales agents. The ATM Agreement allows us to sell our common stock for gross proceeds of up to $75.0 million from time to time, through at-the-market offerings or to the sales agents as principal purchasers (“ATM Offering”). As there is no commitment for future sales of additional shares under the ATM Agreement or the ATM Offering, we cannot predict how much, if any, additional proceeds may be realized. During the three months ended March 31, 2026, we received net proceeds of approximately $12.3 million in cash related to the ATM Offering.
Related Party Borrowings from Dr. Kyeongho Lee and Anapass, Inc.
In November and December 2024, we entered into term loan agreements with Dr. Kyeongho Lee (“Kyeongho Lee”), the chairman of our board of directors, pursuant to which we borrowed $2.9 million and $2.1 million, originally maturing in December 2024 and January 2025, respectively. In October 2025, we partially repaid to Kyeongho Lee $1.4 million of the term loans originally entered into in December 2024. In January and April 2026, we partially repaid to Kyeongho Lee $0.9 million and $1.2 million of the term loan originally entered in November 2024. The remainder of the term loans originally entered into in November and December 2024 are outstanding as of March 31, 2026. In January 2025, we entered into a term loan agreement with Kyeongho Lee, pursuant to which we borrowed $4.4 million maturing in February 2025, which remained outstanding as of March 31, 2026. For the three months ended March 31, 2026, we incurred penalties of 3% of principal per month on loans in the amount of $0.6 million that are past their maturity dates, calculated daily until the principal and accrued interest are paid. Outstanding penalties payable to Kyeongho Lee as of March 31, 2026 are $2.7 million.
In December 2024, we entered into a term loan agreement with Anapass, Inc., our major stockholder, pursuant to which we borrowed $3.4 million maturing in December 2025. In March 2025, we entered into a term loan agreement with Anapass, Inc., pursuant to which we borrowed $3.1 million maturing in March 2026. In July 2025, we entered into a term loan agreement with Anapass, Inc., pursuant to which we borrowed $2.1 million maturing in July 2026. In August 2025, we entered into a term loan agreement with Anapass, Inc., pursuant to which we borrowed $1.4 million maturing in August 2026. In September 2025, we entered into a term loan agreement with Anapass, Inc., pursuant to which we borrowed $10.7 million maturing in September 2026. In July 2025, we executed an amendment with Anapass, Inc. to extend the maturity date of a term loan, originally entered into in July 2016 with a principal of $4.5 million, from July 2025 to July 2026. In November 2025, we executed an amendment with Anapass, Inc. to extend the maturity date of a term loan, originally entered into in May 2022 with a principal of $2.2 million, from November 2025 to November 2026. In December 2025, we executed an amendment with Anapass, Inc. to extend the maturity date of the term loan originally entered into in December 2024 with a principal of $3.4 million from December 2025 to December 2026. In March 2026, we executed an amendment with Anapass, Inc. to extend the maturity date of the term loan originally entered into in March 2025 with a principal of $3.1 million from March 2026 to March 2027 and change the annual interest rate from 6.5% to 7.0%.

Table of Contents
2024 Convertible Promissory Notes
In February 2026, we executed an amendment to extend the maturity date of the 2024 convertible promissory notes from February 2026 to February 2028. In connection with the execution of this amendment, we issued a warrant to purchase 500,000 shares of our common stock to a holder of the 2024 convertible promissory notes (“February 2026 Warrant”). The February 2026 Warrant was immediately exercisable at $2.50 per share and will expire three years following the issuance date.
Indigo Convertible Promissory Notes
In December 2025, we entered into a convertible promissory note purchase agreement with Indigo Capital LP (“Indigo”), which provides for the issuance of convertible promissory notes of up to $20.0 million in aggregate (“Indigo Notes” or “Indigo Facility”). Each Indigo Note will be issued at a purchase price equal to 93% of its principal amount and matures 24 months from its issuance date and is convertible into our common stock at any time on or before its maturity date unless redeemed by us. The conversion price is 90% of the reference price, which is calculated as the lowest volume-weighted average price (“VWAP”) of our common stock over the three trading days immediately preceding Indigo's submission of a conversion notice. The reference price is subject to a floor of 96% of the average VWAP during this three-day period. No interest is payable on the Indigo Notes, and we have an optional redemption right beginning 12 months following the issuance of the Indigo Notes. Redemption between 12 and 18 months from issuance carries a 7% premium on the principal amount redeemed, increasing to 14% if redeemed between 18 months and maturity.
In December 2025, we issued two Indigo Notes, each with a principal amount of $1.0 million, and received gross proceeds of $1.9 million, reflecting the discount at issuance. In December 2025, the first Indigo Note was converted into 903,710 shares of our common stock. During the three months ended March 31, 2026, we issued three Indigo Notes, each with a principal amount of $1.0 million, and received gross proceeds of $2.8 million, reflecting the discount at issuance. During the three months ended March 31, 2026, the Indigo Notes with principal amount of $4.0 million converted into 4.4 million shares of common stock. No Indigo Notes remained outstanding as of March 31, 2026.
Obsidian Convertible Promissory Notes
In March 2026, we entered into a convertible promissory note purchase agreement with Obsidian Global GP, LLC (“Obsidian”), which provides for the issuance of convertible promissory notes of up to $20.0 million in aggregate (“Obsidian Notes” or “Obsidian Facility”). Through March 31, 2026, no Obsidian Notes have been issued.
Each Obsidian Note will be issued at a purchase price equal to 96.5% of its principal amount. Each Obsidian Note will mature 24 months from its issuance date and is convertible into our common stock at any time on or before its maturity date unless redeemed by us. The conversion price is 95% of the reference price, which is calculated as the lowest VWAP of our common stock over the three trading days prior to the submission of a conversion notice by Obsidian. No interest is payable on the Obsidian Notes, and we have an optional redemption right beginning 12 months following the issuance of the Obsidian Notes. Redemption between 12 and 18 months from issuance carries a 7% premium on the principal amount redeemed, increasing to 14% if redeemed between 18 months and maturity.
Additional Liquidity Needs
We expect significant ongoing operating expenditures to be necessary to successfully implement our business plan and market our products. Production shipments of our 5G products commenced in the fourth quarter of 2025, and we expect continued significant related expenditures, including production-related costs such as mask sets, wafers, and assembly and test costs, most of which will be incurred prior to the commencement of manufacturing and production.
As of March 31, 2026, our existing sources of liquidity include $7.2 million in cash and cash equivalents. Our internal sources of liquidity consist primarily of cash on hand and cash generated from operations (which has historically been negative). Our external sources include our ability to raise capital under our shelf registration statement, including the ATM, ELOC, the Indigo Facility and Obsidian Facility, and debt financings and extensions with lenders, including related parties. These external sources represent potential unused liquidity; however, the amount and timing of any proceeds depend on market conditions, contractual limitations, and our ability to satisfy applicable conditions. As of March 31, 2026, we have borrowings with a total principal amount of $52.1 million, which are contractually due within 12 months from this Quarterly Report. In addition, we have borrowings with a total principal amount of $0.7 million and a convertible promissory note with a principal amount of $5.0 million, which are contractually due between one and three years from this Quarterly Report. We will need to start generating positive cash flows, renegotiate our existing debt obligations and raise additional capital through debt or equity financing. There can be no assurance that such additional debt or equity financing will be available on terms acceptable to us or at all.

Table of Contents
If we do not have sufficient funds to make such payments, or if we cannot extend the terms of our existing commercial loans or to raise additional capital through equity or debt offerings, the payments can be delayed, which may adversely affect our business operations and financial performance. While we believe we will be able to secure additional capital and funding in the next 12 months to sustain our operations, there remains a substantial doubt about our ability to continue as a going concern. For a more detailed description of such risks, please see the section entitled “Risk Factors” disclosed in our Annual Report filed with the SEC on March 25, 2026.
We intend to mitigate the risk of a working capital deficit by continuing to pursue our 5G sales strategy and execute appropriate actions to secure funding as a publicly traded company, including the extension and refinancing of existing loans, public or private equity offerings, debt financings, and other means. In the second fiscal quarter of 2025, we filed a universal shelf registration statement on Form S-3 that allows us to raise up to $200.0 million through the issuance of our securities, including the $75.0 million for the ATM Offering.We have historically been able to raise capital through the issuance and sale of equity and equity-linked instruments, such as redeemable convertible preferred stock, convertible promissory notes, and borrowings, although no assurance can be provided that we would continue to be successful in doing so in the future.
We expect to use additional liquidity and our available cash and cash equivalents to finance the following activities:
While we believe we have a reasonable basis for our expectations and will be able to raise additional funds, we cannot provide assurance that we will be able to complete additional financing in a timely manner. In addition, the sale of additional equity securities could result in dilution to our stockholders. The incurrence of indebtedness would result in increased debt service obligations and may include operating and financial covenants that would restrict our operations. We cannot be certain that any financing will be available in the amounts we need or on terms acceptable to us, if at all. Should we enter into definitive collaboration and/or joint venture agreements or engage in business combinations in the future, we may be required to seek additional financing.

Overview of Cash Flows
During the three months ended March 31, 2026 and 2025, we funded our operations primarily through financing activities. This included the proceeds from the issuance of debt instruments, primarily to third parties in the first fiscal quarter of 2026 and related parties in the first fiscal quarter of 2025. We remain dependent on cash inflows from financing activities to fund our operating expenses. The repayment of the outstanding borrowings will require a combination of cash generated from future operations, additional financing activities, and renegotiation of maturity dates. We are continuously evaluating our capital structure and cash flow projections as we work towards meeting our debt obligations and other liabilities.
Operating Activities
Cash used in operating activities of $7.4 million during the three months ended March 31, 2026, was primarily attributable to our net loss of $9.9 million and a net change in our operating assets and liabilities of $3.6 million, partially offset by non-cash adjustments of $6.0 million. Non-cash adjustments consisted primarily of a $3.1 million loss from the change in fair value of warrant liabilities, a $1.3 million loss from the change in fair value of convertible promissory notes, a $0.6 million increase in provision for credit losses, $0.4 million in stock-based compensation, $0.3 million in depreciation and amortization charges, $0.2 million in amortization of operating lease right-of-use assets and $0.2 million related to the fair value of common stock warrants issued in connection with a convertible note extension. The change in our operating assets and liabilities of $3.6 million primarily resulted from a decrease of $2.5 million in accrued and other current liabilities, an increase of $0.6 million in inventory, an increase of $0.5 million in prepaid expenses and other current

assets, an increase of $0.4 million in accounts receivable, and a decrease of $0.2 million in lease liabilities, partially offset by a decrease of $0.3 million in contract assets, an increase of $0.1 million in contract liabilities, and an increase of $0.1 million in other liabilities.
Cash used in operating activities of $8.0 million during the three months ended March 31, 2025 was primarily attributable to our net loss of $7.0 million, non-cash adjustments of $0.8 million, and a net change in our operating assets and liabilities of $0.2 million. Non-cash adjustments consisted primarily of a $1.6 million gain from the change in fair value of warrant liabilities and a $0.3 million gain from the change in fair value of common stock forward liability, partially offset by $0.5 million in stock-based compensation, a $0.3 million increase in provision for credit losses, $0.2 million in depreciation and amortization charges, and $0.2 million in amortization of operating lease right-of-use assets. The change in our operating assets and liabilities of $0.2 million primarily resulted from a decrease of $1.9 million in accrued and other current liabilities, an increase of $0.4 million in contract assets, a decrease of $0.2 million in other liabilities, a decrease of $0.2 million in lease liabilities, an increase of $0.1 million in inventory, and a decrease of $0.1 million in other taxes payable, partially offset by a decrease of $1.1 million in prepaid expenses and other current assets, a decrease of $0.9 million in accounts receivable, an increase of $0.4 million in accounts payable, and an increase of $0.2 million in net defined benefit liabilities.
Investing Activities
Cash used in investing activities during the three months ended March 31, 2026 and 2025 was related solely to the purchases of property and equipment.
Financing Activities
Cash provided by financing activities of $14.1 million during the three months ended March 31, 2026, consisted of $12.7 million in proceeds from the issuance of common stock under the at-market agreement and $2.8 million in proceeds from the issuance of convertible promissory notes, partially offset by a $0.9 million repayment of our bank borrowings and a $0.4 million payment of common stock issuance costs.
Cash provided by financing activities of $7.7 million during the three months ended March 31, 2025 consisted of $7.5 million in proceeds from borrowings and $0.2 million in proceeds received from the issuance of common stock to B. Riley under the Purchase Agreement.
Commitments and Contractual Obligations
We have material commitments and contractual obligations, including leases, purchase commitments, and research and development agreements. We have various operating leases, under which we lease office equipment and office space. The operating leases have various expiration dates through 2028.
We have certain commitments for outstanding purchase orders related to the manufacture of certain wafers utilized by the Company and other services, and we have entered into a material research and development agreement. See Note 7 to our unaudited condensed consolidated financial statements included in this Quarterly Report for more information regarding our additional commitments and contractual obligations.
We have certain debt agreements in place related to convertible promissory notes and borrowings. See Note 6 to our unaudited condensed consolidated financial statements included in this Quarterly Report for more information regarding our debt arrangements.
Critical Accounting Estimates
Our management’s discussion and analysis of our financial condition and results of operations is based on our unaudited condensed consolidated financial statements, which are prepared in accordance with accounting principles generally accepted in the United States of America. The preparation of our unaudited condensed consolidated financial statements requires us to make estimates and assumptions that affect the reported amounts and related disclosures. We base our estimates on historical experience and other factors we believe are reasonable under the circumstances, which form the basis for judgments about the carrying value of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions due to inherent uncertainty in making them, and any such differences may be material.
There have been no material changes to our critical accounting estimates from those described in “Management’s Discussion and Analysis of Financial Condition,” “Results of Operations – Critical Accounting Policies and Significant Judgments and Estimates” disclosed in our Annual Report filed with the SEC on March 25, 2026, except that from the Closing we have certain contracts in our own equity that are subject to liability classification and remeasurement each reporting periods.

Revenue Recognition
Our revenues are generated from the sale of mobile semiconductor solutions, including products and platform solutions for the LTE and 5G industries, as well as development services, and technical advice and maintenance services.
The timing of revenue recognition and the amount of revenue recognized in each case depends on various factors, including the specific terms of each arrangement and the nature of the underlying performance obligations. Revenues from sales of our products are recognized upon transfer of control to the customer, which is generally at the time of shipment. Service revenues from development services, technical advice, and maintenance services are generally recognized over time as these performance obligations are satisfied.
We estimate potential future returns and sales allowances related to current-period product revenue. We analyze historical return rates and changes in customer demand when evaluating the adequacy of returns and sales allowances. Although we believe we have a reasonable basis for our estimates, such estimates may differ from actual returns and sales allowances. These differences may materially impact reported net product revenues and amounts ultimately collected on accounts receivable.
Provision for Credit Losses
Accounts receivable balances are primarily derived from revenues earned from customers located in the United States, China, South Korea, Japan, and Taiwan. We perform ongoing credit evaluations of the financial condition of our customers and distributors, and generally do not require collateral from our customers. We continuously monitor collections and payments from customers and maintain a provision for credit losses based on the collectibility of our customer accounts. We review the provision by considering certain factors such as historical experience, industry data, credit quality, age of balances and current economic conditions that may affect a customer’s ability to pay. Uncollectible receivables are written off when all efforts to collect have been exhausted and recoveries are recognized when they are recovered. We cannot guarantee that we will continue to experience the same credit loss rates that we had in the past. A significant change in the liquidity or financial position of any of our significant customers could materially affect the collectibility of our accounts receivable and our future operating results. The provision for credit losses was $4.6 million and $4.0 million as of March 31, 2026 and December 31, 2025, respectively.
Fair Value of Convertible Promissory Notes
We have made an election to account for certain promissory notes under the fair value option. The convertible promissory notes are recorded at their initial fair value on the date of issuance and then are adjusted to fair value upon any modification and at each balance sheet date thereafter. Changes in the estimated fair value of the convertible promissory notes are recognized as non-cash gains or losses in the unaudited condensed consolidated statements of operations within other income (expenses), net.
Our convertible promissory notes are valued using a discounted cash flow (“DCF”) model or a binomial lattice model (“BLM”), both of which are Level 3 fair value measurements. Significant assumptions used in the DCF include the remaining term and discount rate. Significant assumptions used in the BLM include volatility, remaining term, risk-free rate, and credit spread.
Contracts in Own Equity – Fair Value of Liability-Classified Warrants
We classify share-settled contracts, including warrants to purchase shares of the Company’s common stock, that do not meet the indexation guidance as liabilities. At the end of each reporting period, these liability-classified instruments are remeasured using an option-pricing model or the BLM. Significant assumptions are used in determining the fair value of our warrants and include volatility and the risk-free rate.
Recent Accounting Pronouncements
See Note 2 to our unaudited condensed consolidated financial statements included herein for more information about recent accounting pronouncements, the timing of their adoption, and our assessment, to the extent we have made one yet, of their potential impact on our financial condition and results of operations.
JOBS Act Accounting and Emerging Growth Company Elections
We are an “emerging growth company” (“EGC”), as defined in the JOBS Act. Under the JOBS Act, EGCs can delay adopting new or revised accounting standards issued after the enactment of the JOBS Act until those standards apply to private companies.
We have elected to use this extended transition period for complying with certain new or revised accounting standards that have different effective dates for public and private companies until the earlier of the date we (i) are no longer an EGC or (ii) affirmatively and irrevocably opt out of the extended transition period provided in the JOBS Act. As a result, our unaudited condensed consolidated

financial statements may or may not be comparable to companies that comply with new or revised accounting pronouncements as of the public companies’ effective dates.
Our EGC status commenced upon the completion of the initial public offering of Concord III in November 2021 and is expected to continue for up to five years from this date through November 2026, unless certain disqualifying events occur earlier, such as achieving large accelerated filer status.
Smaller Reporting Company Status
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 EGC. We have elected to 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 the market value of 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 the market value of 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.
Item 3. Quantitative and Qualitative Disclosures About Market Risk.
We are a “smaller reporting company”, as defined by Rule 12b-2 of the Securities and Exchange Act of 1934, as amended (the Exchange Act), and in Item 10(f)(1) of Regulation S-K, and are not required to provide the information otherwise required under this item.
Item 4. Controls and Procedures.
Disclosure Controls and Procedures
Under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, we conducted an evaluation of the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) as of March 31, 2026. Based on this evaluation, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were effective as of March 31, 2026 to provide reasonable assurance that information required to be disclosed by us in the reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, and that such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure.
Changes in Internal Control Over Financial Reporting
There have been no changes in our internal control over financial reporting identified in connection with the evaluation required by Rule 13a-15(d) and 15d-15(d) of the Exchange Act that occurred during the quarter ended March 31, 2026, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
Inherent Limitation on the Effectiveness of Internal Controls and Procedures
Our management, including our Chief Executive Officer and Chief Financial Officer, does not expect that our disclosure controls or our internal control over financial reporting will prevent all errors and all fraud. A control system, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, have been detected. These inherent limitations include the realities that judgments in decision-making can be faulty, and that breakdowns can occur because of a simple error or mistake. Additionally, controls can be circumvented by the individual acts of some persons, by collusion of two or more people or by management override of the controls. The design of any system of controls is also based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions. Over time, controls may become inadequate because of changes in conditions, or the degree of compliance with policies or procedures may deteriorate. Because of the inherent limitations in a cost-effective control system, misstatements due to error or fraud may occur and not be detected.

There have been no material changes to the risk factors we previously disclosed in our Annual Report filed with the SEC on March 25, 2026. Our operations could also be affected by additional factors that are not presently known to us or by factors that we currently consider immaterial to our business.
