Notes to Unaudited Condensed Consolidated Financial Statements

  1. Organization and Liquidity

Description of Business

GCT Semiconductor Holding, Inc. (formerly known as Concord Acquisition Corp III) 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, B2B and consumer applications.

On March 26, 2024 (the “Closing Date” or “Closing”), Concord Acquisition Corp III (“Concord III”), a Delaware corporation, consummated a series of transactions that resulted in the combination of Gibraltar Merger Sub Inc., a Delaware corporation and a wholly-owned subsidiary of Concord III (“Merger Sub”), and GCT Semiconductor, Inc. ( “Legacy GCT”), pursuant to a Business Combination Agreement, dated November 2, 2023 (as amended, the “Business Combination Agreement”), by and among Concord III, Merger Sub and Legacy GCT. Pursuant to the terms of the Business Combination Agreement, Merger Sub merged with and into Legacy GCT, with Legacy GCT surviving the merger as a wholly-owned subsidiary of Concord III (the “Business Combination”). On the Closing Date, Concord III changed its name from Concord III to “GCT Semiconductor Holding, Inc.”

The Business Combination was accounted for as a reverse recapitalization with Legacy GCT being the accounting acquirer and Concord III identified as the acquired company for accounting purposes. Accordingly, all historical financial information presented in the unaudited condensed consolidated financial statements represent the accounts of Legacy GCT. Subsequent to the Business Combination, the shares and net loss per common share information prior to the Closing have been retroactively restated as shares reflecting the exchange ratio established in the Closing of approximately 0.1868.

Prior to the Business Combination, Concord III’s public shares and public redeemable warrants were listed on the New York Stock Exchange (“NYSE”) under the symbols “CNDB.U,” “CNDB,” and “CNDB.WS,” respectively. On March 27, 2024, the Company’s common stock and public warrants began trading on the NYSE under the symbols “GCTS” and “GCTSW,” respectively. In connection with the Closing, Concord III’s Class A common stock and Class B common stock were recapitalized into a single class of common stock. See Note 3 for additional information.

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 and liabilities and commitments in the normal course of business. Through September 30, 2024, the Company has incurred operating losses and negative cash flows from operating activities and had an accumulated deficit of$557.1 million as of September 30, 2024. The Company’s existing sources of liquidity as of September 30, 2024 include cash and cash equivalents of$1.8 million. The Company has historically funded operations primarily with issuances of capital stock and the incurrence of debt.

In March 2024, the Company received$17.2 million in cash proceeds from the reverse recapitalization and PIPE Financing (as defined in Note 3), net of transaction costs. 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, from time to time, B. Riley up to $50.0 million worth of shares of the Company’s common stock at its request, at any time prior to June 2026, subject to compliance with the required conditions and limitations. Through September 30, 2024, the Company received$7.8 million in net proceeds under the Purchase Agreement.

Management believes that the available financing under the Purchase Agreementand other capital resources available to the Company, including future sales of products and services, will be sufficient to fund the Company’s operations for at least 12 months after the filing date of this Quarterly Report on Form 10‑Q. 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. There can be no assurance that such additional debt or equity financing will be available on terms acceptable to the Company or at all.

  1. 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 unaudited 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, 2023, which are included in the Company’s Form 8‑K filed with the SEC on April 1, 2024. The information as of December 31, 2023 included in the condensed consolidated balance sheets was derived from the audited consolidated financial statements. Certain amounts reported in the audited consolidated financial statements for the year ended December 31, 2023 have been reclassified to conform to the current year’s presentation.

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 and nine months ended September 30, 2024 are not necessarily indicative of the results to be expected for the year ending December 31, 2024 or for any other future annual or interim period.

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, common stock of Legacy GCT prior to the reverse recapitalization, 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.

Fair Value of Financial Instruments

The carrying amount of certain financial instruments held by the Company, such as cash equivalents, accounts receivable, contract assets and liabilities, accounts payable, and accrued and other current liabilities, approximate fair value due to their short maturities. The carrying amount of the liabilities for the convertible promissory notes and the historical convertible promissory notes (see Note 5) represents their fair value. The carrying amounts of the Company’s bank borrowings and lease liabilities approximate their fair values due to the market interest rates that these obligations bear and interest rates available to the Company.

Fair value is defined as the exchange price that would be received for an asset or an exit price paid to transfer a liability in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. The fair value hierarchy defines a three-level valuation hierarchy for disclosure of fair value measurements as follows:

Level 1Unadjusted quoted prices in active markets for identical assets or liabilities.
Level 2Inputs other than quoted prices included within Level 1 that are observable, unadjusted quoted prices in markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the related assets or liabilities.
Level 3Unobservable inputs that are supported by little or no market activity for the related assets or liabilities.

A financial instrument's categorization within the valuation hierarchy is based on the lowest level of input that is significant to the fair value measurement. The Company’s Level 3 financial instruments consist of a common stock forward liability, convertible promissory notes, and warrant liabilities.

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 unaudited condensed consolidated operating results due to the abovementioned 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 determined that provisions for credit losses of approximately$1.1 million and$1.6 million were necessary as of September 30, 2024 and December 31, 2023, respectively.

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.

The Company’s net revenues and accounts receivable are concentrated among a few significant customers, which could expose the Company to financial risk in the event of adverse developments. The following represents the concentration of the Company’s gross accounts receivable among key customers to the extent their share exceeds 10%:

CustomerSeptember 30, 2024December 31, 2023
Customer A27%—%
Customer H20%19%
Customer I12%14%
Customer J12%27%
Customer K—%10%

The following table includes customers that individually accounted for more than 10% of the Company’s net revenues in the periods indicated:

Three Months EndedSeptember 30,Nine Months EndedSeptember 30,
Customer2024202320242023
Customer A—%—%27%—%
Customer B24%—%25%—%
Customer C—%—%12%—%
Customer D—%—%—%25%
Customer F—%13%—%13%
Customer H57%—%20%—%
Customer I—%24%—%—%
Customer J—%47%—%20%

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 diversifying its customer base and exploring 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 loss within stockholders’ deficit. Gains and losses resulting from transactions denominated in a currency other than the functional currency are included in other income (expenses), net in the unaudited condensed consolidated statements of operations. The Company recognized foreign currency exchange losses of$1.1 million and gains of$0.8 million for the three and nine months ended September 30, 2024, respectively. The Company recognized$0.9 million and$1.8 million of foreign currency exchange gains for the three and nine months ended September 30, 2023, respectively.

Convertible Promissory Notes

The Company has elected the fair value option to account for its outstanding convertible promissory notes. Changes in the estimated fair value of the outstanding convertible promissory notes are recognized in other income (expenses), net in the condensed consolidated statements of operations.

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 recognized in other income (expenses), net 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.

Certain Equity Contracts

The Company’s promises to potentially issue additional shares in the future based on certain market conditions, including the Legacy GCT Earnout Shares and the Sponsor Earnout Shares, are discussed in Note 3. These financial instruments were determined to be equity classified and credited to the stockholders’ deficit upon consummation of the Business Combination.

Emerging Growth Company Status

The Company is an emerging growth company, as defined in the Jumpstart Our Business Startups Act of 2012 (the “JOBS” Act). Under the JOBS Act, emerging growth companies 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.

Recent Accounting Pronouncements Adopted

In August 2020, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2020‑06, Debt—Debt with Conversion and Other Options (Subtopic 470‑20) and Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic 815‑40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity (“ASU 2020-06”). ASU 2020‑06 reduces the number of accounting models for convertible instruments and allows more contracts to qualify for equity classification. The Company adopted this guidance effective January 1, 2024 and notedno material impact on the Company’s unaudited condensed consolidated financial statements.

In October 2021, the FASB issued ASU 2021‑08, Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers(“ASU 2021-08”), which provides an exception to fair value measurement for contract assets and contract liabilities related to revenue contracts acquired in a business combination. ASU 2021-08 requires an acquirer to recognize and measure contract assets and contract liabilities acquired in a business combination in accordance with Topic 606. At the acquisition date, an acquirer should account for the related revenue contracts in accordance with Topic 606 as if it had originated the contracts. The Company adopted this guidance effective January 1, 2024 and notedno material impact on the Company’s unaudited condensed consolidated financial statements.

In June 2022, the FASB issued ASU 2022‑03, Fair Value Measurement (Topic 820): Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions (“ASU 2022-03”). ASU 2022-03 clarifies that a contractual restriction on the sale of an equity security should not be considered in measuring the fair value of the equity security and cannot be recognized as a separate unit of account. ASU 2022-03 also requires the investor to disclose the fair value of equity securities subject to contractual sale restrictions, the nature and remaining duration of the restrictions, and the circumstances that could cause a lapse in the restrictions. ASU 2022-03 is effective for annual and interim periods beginning after December 15, 2024, with early adoption permitted. The Company retrospectively adopted this guidance effective July 1, 2024 and notedno material impact on the Company’s unaudited condensed consolidated financial statements.

Recent Accounting Pronouncements Not Yet Adopted

In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures (“ASU 2023-07”), which expands annual and interim disclosure requirements for reportable segments, primarily through enhanced disclosures about significant segment expenses. ASU 2023-07 is effective for annual periods beginning after December 15, 2023 and for interim periods beginning after December 15, 2024, with early adoption permitted. The Company is currently evaluating the effect of the adoption of ASU 2023-07 on its unaudited condensed consolidated financial statements.

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 annual periods beginning after December 15, 2024, 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 effect of the adoption of ASU 2023-09 on its unaudited condensed consolidated financial statements.

  1. Reverse Recapitalization

In connection with the Business Combination described in Note 1, Concord III completed the acquisition of Legacy GCT and acquired 100% of Legacy GCT’s common stock. Legacy GCT received net proceeds of$17.1 million from the PIPE Financing (as defined below). Concord III incurred total direct transaction costs of$13.1 million, which were expensed by Concord III, and of which$0.9 million related to the PIPE Financing. Legacy GCT incurred transaction costs of$8.9 million, consisting of legal, accounting, and other professional fees, which were recorded as additional paid-in capital. Each share of Legacy GCT capital stock received a deemed value of$10.00 per share after giving effect to the applicable exchange ratio of 0.1868. Upon Closing of the Business Combination, the following occurred:

Each share of Legacy GCT common stock issued and outstanding prior to the Closing was cancelled and converted into the right to receive a number of shares of the Company common stock at the exchange ratio of 0.1868.

Each outstanding instrument of Legacy GCT stock options, restricted stock units (“RSUs”), and warrant shares were converted into equivalent Company stock options, RSUs, and warrant shares with the same terms and conditions and at the exchange ratio of 0.1868.

Certain GCT convertible promissory notes, including the CVT Financing (see Note 7), were automatically converted into the right to receive a number of shares of the Company common stock at the conversion price of$6.67 per share (see Note 7).

Immediately after the Closing, the Company’s outstanding common stock included the following components (in thousands):

Shares
Common stock of Concord III outstanding prior to the Business Combination3,941
Less: redemption of Concord III’s common stock(3,766)
Sponsor earnout common stock outstanding prior to the Business Combination8,625
Common stock of Concord III issued and outstanding8,800
Common stock issued in PIPE Financing4,530
Legacy GCT common stock32,503
Total common stock issued and outstanding45,833

The Business Combination was accounted for as a reverse recapitalization under U.S. GAAP because Legacy GCT was determined to be the accounting acquirer, and Concord III was identified as the accounting acquiree for financial reporting purposes. Accordingly, the consolidated financial statements of the Company represent a continuation of the consolidated financial statements of Legacy GCT, with the Business Combination treated as the equivalent of Legacy GCT issuing its common stock for the net assets of Concord III, accompanied by a recapitalization, and the net assets of Concord III were recorded at historical cost, withno goodwill or other intangible assets recorded. The results of operations prior to the Business Combination are those of Legacy GCT.

Legacy GCT was determined to be the accounting acquirer based the following facts and circumstances:

Legacy GCT stockholders comprised a relative majority of the voting power of GCT;

Legacy GCT stockholders had the ability to nominate a majority of the members of the board of directors of GCT;

Legacy GCT’s operations prior to the Business Combination comprised the only ongoing operations of GCT;

Legacy GCT’s senior management comprised the senior management of GCT;

GCT substantially assumed the Legacy GCT name;

Legacy GCT’s headquarters became GCT’s headquarters; and

Concord III did not meet the definition of a business.

PIPE Financing

Concurrent with the execution of the Business Combination Agreement, certain investors entered into agreements and committed to purchase in a private placement an aggregate of 4,529,967 shares of the Company’s common stock (the “PIPE Shares”) at a purchase price of$6.67 per share for an aggregate purchase price of$30.2 million (the “PIPE Financing”) upon the Business Combination Closing. The PIPE Financing was consummated immediately prior to the Closing and resulted in net proceeds of$17.1 million to the Company.

Private Placement Warrants and Public Warrants

In November 2021, Concord III issued warrants to purchase shares of Concord III’s common stock that were assumed by the Company at the Closing of the Business Combination on the same terms and conditions: (i)9,400,000 warrant shares that were issued in a private placement and held by the sponsor and another company (the “Private Placement Warrants”) and (ii)17,250,000 warrant shares that were issued in connection with the initial public offering of Concord III (the “Public Warrants”).

The Private Placement Warrants were reallocated at the Closing of the Business Combination as follows: (i)4,492,650 warrants were vested and retained by the sponsor parties, (ii)2,087,350 warrants were reallocated from the sponsor parties to certain recipients at Legacy GCT’s discretion to incentivize investment, and (iii)2,820,000 were forfeited by the sponsor parties.

Subsequent to the Closing, the outstanding Private Placement Warrants and Public Warrants remained liability-classified as the applicable provisions precluding classification in equity did not change as a result of the Business Combination.

Legacy GCT Earnout Shares

At the Closing of the Business Combination, former Legacy GCT stockholders and other investors of Legacy GCT have the right to receive up to 20,000,000 shares of Company common stock (“Legacy GCT Earnout Shares”). The Legacy GCT Earnout Shares may vest between May 2024 and March 2029 if the volume-weighted average price (“VWAP”) of the Company’s common stock for any 20 trading days within 30 consecutive trading day periods exceeds the following amounts per share (“VWAP Threshold”): (i)one-third of the shares based on the$12.50 per share VWAP Threshold, (ii)one-third of the shares based on the$15.00 per share VWAP Threshold, and (iii)one-third of the shares based on the$17.50 per share VWAP Threshold.

In the event of a future transaction that results in a change in control in which shares of the Company common stock are converted into the right to receive cash or other consideration having a value equal to or in excess of a triggering event, then the Legacy GCT Earnout Shares subject to the applicable triggering event that have not been previously issued will be issued to the Legacy GCT stockholders effective as of immediately prior to the consummation of such transaction. In the event of a transaction that results in a change in control in which shares of Company common stock are converted into the right to receive cash or other consideration having a value less than a triggering event, then the Legacy GCT Earnout Shares subject to the applicable triggering event that have not been previously issued will be forfeited.

The Legacy GCT Earnout Shares were recognized at a fair value of approximately$108.8 million upon the Closing and classified within the stockholders’ deficit as they are indexed solely to the Company’s common stock and are otherwise not precluded from equity classification based on their settlement provisions. Under the reverse recapitalization method of accounting, the fair value of the Legacy GCT Earnout Shares was treated as a deemed dividend and, in the absence of retained earnings, credited to additional paid-in capital without any impact on the stockholders’ deficit balances.

Sponsor Earnout Shares

Concurrently with entering into the Business Combination Agreement, the sponsor parties and the Company entered into that certain sponsor support agreement, as amended, modified, or supplemented (the “Sponsor Support Agreement”). Pursuant to the terms of the Sponsor Support Agreement, the sponsor parties have the right to receive up to 1,920,375 shares of the Company's common stock (“Sponsor Earnout Shares”). The Sponsor Earnout Shares are legally outstanding and remain unvested through September 30, 2024. The Sponsor Earnout Shares may vest between September 2024 and March 2029 if the VWAP of the Company’s common stock for any 20 trading days within 30 consecutive trading day periods exceeds the following VWAP Thresholds: (i)one-third of the shares based on the$12.50 per share VWAP Threshold, (ii)one-third of the shares based on the$15.00 per share VWAP Threshold, and (iii)one-third of the shares based on the$17.50 per share VWAP Threshold.

The Sponsor Earnout Shares were recognized at a fair value of approximately$10.4 million upon the Closing and classified within the stockholders’ deficit as they are indexed solely to the Company’s common stock and are otherwise not precluded from equity classification based on their settlement provisions. Under the reverse recapitalization method of accounting, the fair value of the Sponsor Earnout Shares was treated as a deemed dividend and, in the absence of retained earnings, credited to additional paid-in capital without any impact on the stockholders’ deficit balances.

In July 2024, the number of Sponsor Earnout Shares subject to the market-based vesting condition was reduced to 570,796 shares of the Company’s common stock, as the sponsor parties did not meet the required performance condition for the entire grant. The remaining 1,349,579 shares previously included in the outstanding common stock were forfeited. No adjustments to the stockholders' deficit are required upon the forfeiture of the share-based awards that contain market conditions.

  1. Commitments and Contingencies

Litigations

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 September 30, 2024.

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 noncancelable. 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 September 30, 2024, the Company had outstanding noncancelable purchase commitments for these production agreements of $0.2 million.

Samsung Agreement Liability Release

In July 2020, the Company entered into a research and development agreement with Samsung Electronics Co., Ltd (“Samsung”). According to the agreement, the Company would design 5G chip products and Samsung would provide development and intellectual property support, mass production set up support including mask sets for manufacturing and engineering sample chip supply to the Company for a specific product. The total fee amount for the research and development (“R&D”) services pursuant to the agreement was$21.1 million. The Company bore the risk of R&D failure and was obligated to pay the$21.1 million total fee based on milestones defined in the agreement, of which$11.7 million was due based on development milestones and$9.4 million of additional NRE (“non-recurring engineering”) was to be paid within a maximum of 4 years after the planned product first shipment date. The Company recognized R&D expenses based on an estimate of the percentage completion of services provided by Samsung during the respective financial reporting period. In the first quarter of 2024, Samsung agreed to unconditionally release the Company from payment for work Samsung had completed to date because it had not met certain of the development milestones and due to a change in Samsung’s business strategy. As a result, the Company recognized a gain of$14.6 million upon such unconditional release of its liability to Samsung. During the period ended March 31, 2024, the parties mutually agreed that the agreement had expired and there were no remaining obligations of either party under the agreement.

Alpha Foundry Product Development Agreement

In February 2024, the Company and Alpha Holdings Co., Ltd. (“Alpha”) entered into a foundry product development agreement related to 5G chip development for a total fee of$7.6 million.

B. Riley Purchase Agreement

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$50.0 million worth of shares of its common stock (“Commitment Amount”), subject to certain limitations and conditions at the Company’s sole discretion. The price per share payable by B. Riley on each trading day represents an amount equal to 98% of the VWAP of the Company’s common stock for the applicable pricing period. The Purchase Agreement requires settlement in registered shares. In May 2024, the Company filed a registration statement on Form S-1 with the SEC, which became effective on June 6, 2024 (“Registration Statement”). The Company may sell shares of its common stock to B. Riley through June 2026 up to the Commitment Amount so long that it remains in compliance with the Purchase Agreement.

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 day or less, and the Company recognized a liability of$0.6 million related to the freestanding common stock forward contract. The fair value of the common stock forward liability represents the probability-adjusted present value of the discount to be granted to B. Riley with respect to the sales of its common stock under the Purchase Agreement compared to the VWAP of the company’s common stock for the applicable pricing period.

In connection with the Purchase Agreement, the Company issued 56,818 shares of its common stock (“Commitment Shares”), which included a make-whole provision requiring the Company to reimburse B. Riley in cash if the fair value of these shares is less than$0.25 million. The Company recognized this amount as a liability which remained outstanding as of September 30, 2024 since the Commitment Shares remained unsold by B. Riley.

During the three months ended June 30, 2024, the Company sold an aggregate of 678,462 shares of common stock for$3.3 million, of which$0.5 million was withheld by B. Riley against the outstanding amounts payable, and$2.8 million was received by the Company in cash.

During the three months ended September 30, 2024, the Company sold an aggregate of 1,421,715 shares of common stock for $5.5 million. B. Riley withheld an additional $0.5 million from the aggregate proceeds against the outstanding amounts payable, and $5.0 million was received by the Company in cash.

Issuance of Common Stock to Underwriter

In April 2024, the Company authorized the issuance of 110,000 shares of its common stock to an underwriter previously involved in activities leading to the Business Combination, contingent on the Registration Statement’s effectiveness. The Company determined that its obligation to issue the underwriter shares met the criteria for equity classifications, and the underlying shares of common stock were issued in June 2024. Based on the timing of approval, the Company recognized $0.7 million in charges to equity and included this amount in general and administrative expenses for thethree months ended June 30, 2024.

Private Placement

In September 2024, the Company executed a securities purchase agreement with Anapass, Inc, and issued 741,603 shares of common stock (“Anapass Shares”) and 148,320 equity-classified common stock warrants(“Anapass Warrants”) in exchange for $2.2 million in cash (“Private Placement”). The Company allocated the proceeds based on the relative fair value of the securities issued, including $2.0 million to the Anapass Shares and $0.2 million to the Anapass Warrants. The Anapass Warrants are immediately exercisable at $3.02 per share and will expire five years following the issuance date. Anapass, Inc. remains subject to a lock-up and market stand-off agreement for any shares and share-based instruments issued to it by the Company through March 2025.

Common Stock Reserved for Issuance

Upon the Closing of the Business Combination in March 2024, the Company increased its total number of authorized shares to 440,000,000 shares, consisting of 400,000,000 shares of common stock and 40,000,000 shares of preferred stock.

In March 2024, the Company adopted the 2024 Omnibus Incentive Compensation Plan (the “2024 Plan”), under which 3,983,334 shares of common stock were initially reserved for issuance.

Founder Awards to Board of Directors

In 2021, an aggregate of 90,000 shares of common stock were transferred to three members of Concord III’s board of directors (“Founder Shares”). The Founder Shares contained double-trigger vesting, which required continuous service and a liquidity event for any shares to vest. As the required conditions were met upon the Closing, the Company recognized $0.9 million of stock-based compensation upon the Closing in March 2024.

Restricted Stock Units

In December 2023, various employees and directors of Legacy GCT were granted 392,000 RSUs that contain both a performance condition based upon a liquidity event and a service vesting condition such that (subject to the liquidity event condition being satisfied) the RSUs vest in four equal annual installments from the grant date (“2023 RSUs”). The liquidity condition was met upon the Closing.

In June 2024, the Company granted to the members of its board of directors certain share-based awards with a fixed monetary amount of $0.7 million equally allocated among six grantees (“2024 RSUs”). The number of shares issuable to each grantee under the 2024 RSUs is calculated by dividing one-fourth of the allocated fixed monetary amount by the closing price of the Company’s common stock at the end of each fiscal quarter between April 1, 2024 and March 31, 2025. The RSUs will vest on March 31, 2025, subject to the grantees’ continuous service to the Company and will be settled in common stock on various dates in 2026 and 2027. The 2024 RSUs are initially classified as a liability and reclassified to equity up to the monetary amount for which the number of shares to be issued becomes determinable. Through September 30, 2024, this determination was made for 80,916 shares based on the closing price of the Company’s common stock as of each fiscal quarter-end after the grant date.

In August 2024, the Company granted various employees 140,000 RSUs that vest in four equal annual installments subject to continuous service.

  1. Income Taxes

For financial reporting purposes, the Company’s effective tax rate used for the interim periods is based on the estimated full-year income tax rate. For the three and nine months ended September 30, 2024, the Company’s effective tax rate differs from the statutory rate primarily due to the valuation allowance recorded against the net deferred tax asset balance.

For the nine months ended September 30, 2024 and 2023, the Company recorded income tax of $0.2 million and $0.1 million, respectively. The effective tax rate is (2.6)% and (1.0)% fornine months ended September 30, 2024 and 2023, respectively. Through September 30, 2024, the Company was not under examination by any taxing authority.

As of September 30, 2024 the Company had unrecognized tax benefits of $3.1 million of which $1.7 million would currently affect the Company’s effective tax rate if recognized due to the Company’s deferred tax assets being fully offset by a valuation allowance. The Company does not anticipate that the amount of unrecognized tax benefits relating to tax positions existing as of September 30, 2024 will significantly increase or decrease within the next twelve months. There wasno interest expense or penalties related to unrecognized tax benefits recorded as of September 30, 2024.

A number of years may elapse before an uncertain tax position is audited and finally resolved. While it is often difficult to predict the final outcome or the timing of resolution of any particular uncertain tax position, the Company believes that its reserves for income taxes reflect the most likely outcome. The Company adjusts these reserves, as well as the related interest, considering changing facts and circumstances.
