Rhea-AI Filing Summary

SEALSQ Corp (LAES) reported sharply higher scale for the six months ended June 30, 2026, with net sales of $11.2 million, up from $4.8 million a year earlier, driven by its semiconductor, quantum technology and cybersecurity offerings. Despite this growth, SEALSQ recorded an operating loss of $32.2 million and a net loss of $27.8 million, wider than the prior period. Operating cash flow was negative $23.7 million, but the company strengthened its balance sheet through $125.0 million of common stock issuance, ending with $486.1 million in cash and restricted cash and working capital of $485.7 million. Management states that, based on cash projections through September 30, 2027, SEALSQ has sufficient liquidity and prepares the accounts on a going concern basis.

SEALSQ completed two strategic transactions on June 1, 2026: a controlling 55.5% stake in Wecan Group SA, accounted for as a business combination with $6.2 million of goodwill, and a $5.8 million asset acquisition of Miraex SA focused on quantum photonic technology. The company also invested $7.0 million in EeroQ SAFEs and about $17.5 million in Quobly SAS preferred shares to deepen its quantum-computing ecosystem. Total assets rose to $614.6 million and total equity to $562.1 million, including growing noncontrolling interests from Wecan.

Positive

  • Net sales grew to $11.2 million from $4.8 million year over year, more than doubling scale in six months.
  • Cash and restricted cash reached $486.1 million, supported by $125.0 million of new common stock issuance, providing substantial liquidity.
  • Total shareholders’ equity increased to $562.1 million from $461.5 million, reflecting strong capital inflows and higher asset base.
  • SEALSQ completed strategic quantum and blockchain deals, including a 55.5% stake in Wecan and a $5.8 million Miraex asset acquisition, expanding technology capabilities.

Negative

  • Net loss widened to $27.8 million from $20.0 million, with an operating loss of $32.2 million despite higher revenue.
  • Net cash used in operating activities was $23.7 million, indicating significant cash burn from operations in the half year.
  • Research & development and general & administrative expenses rose substantially to $8.7 million and $23.1 million, respectively, pressuring profitability.
  • The Wecan acquisition added $6.2 million of goodwill, increasing future impairment risk if expected benefits are not realized.

Filing Explained

By June 30, 2026, SEALSQ had completed two acquisitions and reported 223,430,764 ordinary shares outstanding versus 191,525,129 at December 31, 2025.

The September 14 Form 6-K furnishes unaudited interim financial statements as of June 30, 2026; it records the completed June 1, 2026 acquisitions of a 55.52% controlling interest in Wecan and 100% of Miraex, and reports 223,430,764 ordinary shares outstanding at June 30 versus 191,525,129 at December 31.

Wecan was recorded as a business combination funded through a cash capital increase, with noncontrolling interests retained by other shareholders and a discretionary call option on their remaining shares beginning three years after the acquisition. Miraex was recorded as an asset acquisition, so its purchase cost was allocated to acquired assets and liabilities and no goodwill was recognized.

The filing also corrects prior-period comparative figures for previously unrecorded Swiss stamp-duty liabilities on share issuances; this is a retrospective presentation correction rather than a new financing. The higher ordinary-share count reduces an existing holder's percentage ownership absent offsetting changes.

The Wecan purchase-price allocation remains provisional, with valuations and related goodwill subject to completion within the one-year measurement period; the next stated annual goodwill impairment test is October 1, 2026.

going concern financial
"The Group incurred a net operating loss... and had positive working capital... SEALSQ has sufficient liquidity to fund operations."
Going concern is the accounting assumption that a company will keep operating and meeting its obligations for the foreseeable future. The phrase matters most when a company or its auditors disclose substantial doubt about it, a formal warning that the business may not have enough resources to continue without raising money, restructuring, or selling assets. That language in a filing or press release signals elevated financial risk.
business combination financial
"The acquisition was accounted for as a business combination in accordance with ASC 805."
A business combination happens when two or more companies join together to operate as one, like two friends merging their teams into a single group. This is important because it can change how companies grow, compete, and make money, often making them bigger and more powerful in the market.
asset acquisition financial
"The transaction was accounted for as an asset acquisition in line with ASC 805."
An asset acquisition is when a company buys specific pieces of another business—such as equipment, buildings, patents, customer lists, or inventory—rather than buying the other company’s stock. For investors, it matters because this lets a buyer add value or cut costs without taking on unwanted liabilities, similar to shopping for and installing only the useful appliances in a house instead of buying the whole property; the move can change future revenue, costs and risk.
noncontrolling interests financial
"Noncontrolling interests were measured at fair value using the implied equity value."
The portion of a subsidiary’s equity and profits that belongs to outside owners rather than the parent company; when a parent reports consolidated results it includes the whole subsidiary but shows the noncontrolling slice separately. Think of a company’s subsidiary as a pie where the parent owns most slices but some are held by other investors — noncontrolling interests tell you how much of the pie and its future earnings don’t belong to the parent, which affects how much profit and net assets are truly attributable to the parent’s shareholders.
Simple Agreements for Future Equity financial
"the Group entered into Simple Agreements for Future Equity (“SAFEs”) with EeroQ Corporation."
A simple agreement for future equity is a lightweight contract where an investor gives money now in exchange for the right to receive company shares at a later financing event, rather than buying shares immediately. Think of it as a voucher or IOU that converts into stock when the company raises a priced round; it matters to investors because it determines when they become owners, how much of the company they ultimately own, and how early risk and future dilution are shared.
measurement alternative financial
"the investment is measured using the measurement alternative and is recorded at cost, less impairment."

SEALSQ Corp Consolidated Financial Statements as of June 30, 2026

 

5. Notes to the Condensed Consolidated Financial Statements

 

Note 1. The SEALSQ Group

 

SEALSQ Corp, together with its consolidated subsidiaries (“SEALSQ” or the “Group” or the “SEALSQ Group”), was incorporated in April 2022 under the laws of the British Virgin Islands (“BVI”). The SEALSQ Group’s registered office is located in Tortola, BVI. The Group’s ordinary shares are listed on the Nasdaq Global Select Market under the ticker symbol “LAES” since May 23, 2023.

 

On January 1, 2023, the Group acquired 100% of the outstanding shares of SEALSQ France SAS (formerly WISeKey Semiconductors SAS) and its subsidiaries. Prior to this acquisition, the Group did not have any operations.

 

On August 4, 2025, SEALSQ acquired 100% of IC’Alps SAS, thereby broadening its services to Application-Specific Integrated Circuit (“ASIC”) design. On June 1, 2026, SEALSQ acquired 100% of Miraex SA (“Miraex”), a Swiss technology company focused on photonic integrated circuit technologies for quantum computing and quantum communications, and a controlling interest in the Wecan Group SA (“Wecan”), a Swiss company operating a blockchain-based digital infrastructure platform focused on secure, decentralized data exchange for the banking sector.

 

The Group operates in the semiconductor, quantum technology and cybersecurity industries. It designs and markets secure semiconductor products, including post-quantum secure elements, Trusted Platform Modules and custom ASICs, together with Public Key Infrastructure (“PKI”) and managed digital identity services, for applications spanning Internet of Things (“IoT”), industrial, government and digital-payment markets. The Group’s roadmap includes obtaining regulatory certifications for, and commercializing, its post-quantum secure semiconductor products. With its latest acquisitions, the Group aims to deploy secure quantum communication solutions.

 

Note 2. Future operations and going concern

 

The Group recorded a loss from operations in this reporting period and the accompanying condensed consolidated financial statements have been prepared assuming that the Group will continue as a going concern.

 

The Group incurred a net operating loss of USD 32.2 million in the six months ended June 30, 2026, and had positive working capital of USD 485.7 million as of June 30, 2026. Based on the Group’s cash projections up to September 30, 2027, SEALSQ has sufficient liquidity to fund operations. We note that, historically, the Group has been dependent on financing from its parent, WISeKey International Holding Ltd, or other investors to augment the operating cash flow to cover its cash requirements.

 

Based on the foregoing, Management believes it is correct to present these figures on a going concern basis.

 

Note 3. Basis of presentation

 

The condensed consolidated financial statements are prepared in accordance with the Generally Accepted Accounting Principles in the United States of America (“US GAAP”) as set forth in the Financial Accounting Standards Board’s (FASB) Accounting Standards Codification (ASC). All amounts are in United States dollars (“USD”) unless otherwise stated. 

 

These unaudited condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Group’s annual financial statements for the year ended December 31, 2025, as filed in the 20-F on March 31, 2026.

 

The Group’s interim period results do not necessarily indicate the results that may be expected for any other interim period or for the full fiscal year. The significant accounting policies applied in the annual consolidated financial statements of the Group as of December 31, 2025, contained in the Group’s Annual Report have been applied consistently in these unaudited condensed consolidated financial statements.

 

F-9

SEALSQ Corp Consolidated Financial Statements as of June 30, 2026

 

It is management’s opinion that all adjustments necessary for a fair statement of the results for the interim periods have been made. These unaudited condensed consolidated financial statements include a description of the nature and amount of material adjustments other than normal recurring adjustments.

 

Acquisition of Miraex SA

 

On June 1, 2026, SEALSQ acquired 100% of the outstanding shares and voting rights of Miraex. The Group concluded that the acquired set did not meet the definition of a business under ASC 805 and accounted for the transaction as an asset acquisition under ASC 805-50. Miraex’ assets, liabilities and results of operations have been included in the Group’s condensed consolidated financial statements from June 1, 2026. See Note 7 for further information.

 

The acquisition supports SEALSQ’s development of secure quantum communication solutions.

 

Acquisition of Wecan Group SA

 

On June 1, 2026, SEALSQ acquired a 55.5% controlling interest in Wecan. The acquisition was accounted for as a business combination in accordance with ASC 805, with SEALSQ identified as the accounting acquirer. Wecan’s assets, liabilities and results of operations have been included in the Group’s condensed consolidated financial statements from June 1, 2026. See Note 6 for further information.

 

The acquisition enhances SEALSQ’s digital security and trusted data-exchange solutions for sensitive industries.

 

Additional paid-in capital

 

During our 2025 financial reporting process, we ascertained that, although SEALSQ is a BVI company with a direct listing on a U.S. stock exchange, its tax residency status means that it is liable for stamp duties in Switzerland for its share issues. This resulted in the Group not accruing for stamp duties on its share issues since inception, which affected SEALSQ’s equity presentation of capital increases in the financial statements ended June 30, 2024, and December 31, 2023. The error resulted in an overstatement of the capital increase impacts in additional paid-in capital and an understatement of other current liabilities. We assessed that there was not a substantial likelihood that the error would have been viewed by the reasonable investor as having significantly altered the “total mix” of information made available, and as such concluded that a “little r” restatement was required. In application of ASC 250, we corrected the error in the current year comparative financial statements by adjusting the prior period information.

 

The tables below show the effect of the adjustment of the prior period information on the Condensed Consolidated Statements of Comprehensive Income / (Loss), Condensed Consolidated Statements of Changes in Shareholders’ Equity and Condensed Consolidated Statements of Cash Flows. The related interest accrual in relation to the late payment in prior years was deemed immaterial and was not adjusted in retained earnings, instead, a total cumulated interest expense of $30,138 was recorded in the income statement in the six months ended June 30, 2025 ($4,884 arising in 2023, $14,563 in 2024 and $10,691 in the six months ended June 30, 2025).

Note 4. Summary of significant accounting policies

 

Asset Acquisition

 

The Group evaluates acquisitions under ASC 805 to determine whether the acquired set meets the definition of a business. If substantially all of the fair value of the gross assets acquired is concentrated in a single identifiable asset or group of similar identifiable assets, the acquired set is not considered a business.

 

Acquisitions that do not meet the definition of a business are accounted for as asset acquisitions under ASC 805-50. The cost of an asset acquisition includes the consideration transferred and direct transaction costs and is allocated to the assets acquired and liabilities assumed based on their relative fair values. No goodwill is recognized.

 

Investment in Equity Securities

 

Equity securities are any security representing an ownership interest in an entity or the right to acquire or dispose of an ownership interest in an entity at fixed or determinable prices, in accordance with ASC 321, i.e., investments that do not qualify for accounting as a derivative instrument, an investment in consolidated subsidiaries, or an investment accounted for under the equity method.

 

The Group accounts for these investments in equity securities at fair value at the reporting date, except for those investments without a readily determinable fair value where the Group has elected the measurement at cost minus impairment, if any, plus or minus changes resulting from observable price changes in orderly transactions for the identical or a similar investment of the same issuer, in line with ASC 321. Changes in fair value are accounted for in the income statement as a non-operating income/expense.

 

Segment Reporting

 

Our chief operating decision maker, who is also our Chief Executive Officer, regularly reviews information collated into two segments for purposes of allocating resources and assessing budgets and performance. We report our financial performance based on this segment structure described in Note 38.

 

Recent Accounting Pronouncements

 

Adoption of new FASB Accounting Standard in the current year – Prior-Year Financial Statements not restated:

 

As of January 1, 2026, the Group adopted Accounting Standards Update (ASU) 2024-04, Debt - Debt with Conversion and Other Options (Subtopic 470-20): Induced Conversions of Convertible Debt Instruments, which clarifies the accounting treatment for certain settlements of convertible debt instruments that do not occur under the instruments’ preexisting terms.

 

ASU 2024-04 introduces a “preexisting contract approach” to determine whether an inducement offer should be accounted for as an induced conversion. Under this approach, an inducement offer is considered to preserve the form and amount of consideration if it provides the debt holder with at least the same consideration as the original conversion terms of the instrument. The assessment is based on the terms as they existed one year before the offer acceptance date, especially if the instrument was modified within that period. Additionally, the standard clarifies that induced conversion accounting applies to convertible debt instruments within the scope of Subtopic 470-20 that are not currently convertible, provided the instrument contained a substantive conversion feature at both its issuance date and the inducement offer acceptance date. There was no impact on the Group’s results upon adoption of the standard.

 

As of January 1, 2026, the Group adopted Accounting Standards Update (ASU) 2025-05, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses for Accounts Receivable and Contract Assets, which provides targeted simplifications to the current expected credit loss (CECL) model for certain short-term financial assets arising from revenue transactions.

 

ASU 2025-05 introduces a practical expedient that allows entities to assume that current economic conditions as of the balance-sheet date remain unchanged for the remaining life of certain current accounts receivable and current contract assets when estimating expected credit losses. This eliminates the need to develop forward-looking macroeconomic forecasts for these short-term assets, reducing complexity and documentation burden. The standard also includes related disclosure requirements for entities electing the practical expedient or subsequent collection approach. There was no impact on the Group’s results upon adoption of the standard.

 

F-12

SEALSQ Corp Consolidated Financial Statements as of June 30, 2026

 

New FASB Accounting Standard to be adopted in the future:

 

In November 2024, the FASB issued ASU 2024-03, Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses, which updates mandates that public business entities provide more detailed disclosures about specific expense categories in their financial statement notes, enhancing transparency for investors.

 

Summary: Entities are required to disaggregate certain expense captions presented on the income statement into the following natural expense categories, such as purchases of Inventory, Employee compensation, Depreciation and Intangible Asset Amortization. These disaggregated expenses must be presented in a tabular format within the notes to the financial statements for both annual and interim reporting periods. Additionally, entities are required to disclose the total amount of selling expenses and provide their definition.

 

Effective Date: ASU 2024-03 is effective for annual reporting periods for public business entities for fiscal years beginning after December 15, 2026, and for interim reporting periods within fiscal years beginning after December 15, 2027. Early adoption is permitted.

 

The Group expects to adopt the guidance when effective. Management is assessing the impact of the aforementioned guidance on its consolidated financial statements but does not expect it to have a material impact.

 

In September 2025, the FASB issued ASU 2025-06, Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software. This ASU makes targeted improvements to Subtopic 350-40 to increase the operability of the recognition guidance considering different methods of software development.

 

Summary: This update amends Subtopic 350-40 by removing references to prescriptive software development stages and introducing a principle-based approach for capitalizing costs. Under this approach, capitalization begins when management has authorized and committed to funding and it is probable that the project will be completed and used as intended. Additionally, the ASU introduces a framework for assessing significant development uncertainty, clarifies that specific asset disclosures apply to all capitalized internal-use software costs, and consolidates guidance for website development costs into Subtopic 350-40.

 

Effective Date: ASU 2025-06 is effective for all entities for fiscal years beginning after December 15, 2027. Early adoption is permitted.

 

The Group expects to adopt the guidance when effective. Management is assessing the impact of the aforementioned guidance on its consolidated financial statements but does not expect it to have a material impact.

 

In December2025, the FASB issued ASU2025-11, Interim Reporting (Topic270): Narrow Scope Improvements. This update clarifies and refines the guidance in ASC270 to improve how entities prepare and disclose interim financial statements and notes in accordance with U.S. GAAP.

 

Summary: The update specifies that ASC270 applies to all entities that provide a complete set of interim financial statements with notes. It clarifies the form and content of interim financial statements and accompanying disclosures, including a consolidated list of disclosure requirements relevant for interim periods. The ASU also codifies a disclosure principle requiring entities to report material events or changes that occur after the most recent annual reporting period, such as significant changes in estimates, accounting policies, or contingencies. These amendments improve clarity, consistency, and ease of application but do not change the fundamental nature of interim reporting.

 

Effective Date: ASU 2025-11 is effective for public business entities for interim periods within annual periods beginning after December15,2027. Early adoption is permitted. The Group expects to adopt the guidance when effective. Management is assessing the impact of the aforementioned guidance on its interim financial statements but does not expect it to have a material impact.

 

In April 2026, the FASB issued ASU 2026-01, Equity (Topic 505): Initial Measurement of Paid-in-Kind Dividends on Equity-Classified Preferred Stock, which eliminates diversity in practice by providing explicit guidance for instruments that previously lacked specific treatment under U.S. GAAP.

 

F-13

SEALSQ Corp Consolidated Financial Statements as of June 30, 2026

 

Summary: The update clarifies that issuers must initially measure paid-in-kind (PIK) dividends on equity-classified preferred stock using the contractually stated dividend rate rather than the fair value of the underlying shares. It also establishes consistent presentation and disclosure requirements for the issuance of these shares.

 

Effective Date: ASU 2026-01 is effective for all entities for annual reporting periods beginning after December 15, 2026, and interim reporting periods within those annual reporting periods. Early adoption is permitted. The Group expects to adopt the guidance when effective. Management is assessing the impact of the aforementioned guidance on its consolidated financial statements but does not expect it to have a material impact.

 

Note 5. Concentration of credit risks

 

Financial instruments subject to credit risk

 

Financial instruments that are potentially subject to credit risk consist primarily of cash and cash equivalents and trade accounts receivable. Our cash and cash equivalents is mostly held with one large financial institution. Management believes that the financial institution that holds most of our cash and cash equivalents is financially sound and, accordingly, is subject to minimal credit risk. However, to the extent that such deposits exceed the maximum insurance levels, they are uninsured.

 

Customer concentration

 

The Group sells to large, international customers and, as a result, may maintain individually significant trade accounts receivable balances with such customers during the year. We generally do not require collateral on trade accounts receivable.

 

Summarized below are the clients whose revenue was 10% or higher than the respective total consolidated net sales for the six months ended June 30, 2026 and 2025, and the clients whose trade accounts receivable balances were 10% or higher than the respective total consolidated trade accounts receivable balance as of June 30, 2026 and December 31, 2025. In addition, we note that some of our clients are contract manufacturers for the same companies; should these companies reduce their operations or change contract manufacturers, this would cause a decrease in our customer orders which would adversely affect our operating results.

Note 6. Business Combination

 

On June 1, 2026 (the “Acquisition Date”), the Group obtained control of Wecan, a Swiss company operating a blockchain-based digital infrastructure platform focused on secure, decentralized data exchange. The acquisition expands the Group’s secure digital identity and blockchain capabilities and is expected to provide technology, commercial and operational synergies.

 

The Group initially acquired a 31.87% equity interest in Wecan on June 27, 2025, for total consideration of USD 3.5 million and accounted for the investment under the equity method. The carrying amount of the investment was USD 3.4 million as of December 31, 2025. Immediately before the Acquisition Date, the Group continued to own 31.87% of Wecan’s outstanding ordinary shares. Through subscriptions in Wecan capital increases of CHF 5 million (USD 6.4 million at historical rate), the Group increased its ownership to 55.52% of the outstanding ordinary shares (51.93% on a fully diluted basis) and obtained control.

 

The acquisition was accounted for as a business combination achieved in stages in accordance with ASC 805 with SEALSQ identified as the accounting acquirer. The assets, liabilities and results of Wecan have been included in the Group’s condensed consolidated financial statements from June 1, 2026.

 

The form of consideration for the newly acquired interest was cash subscribed through capital increase. The preliminary acquisition-date fair value attributable to the acquisition consisted of the following components:

 

   USD’000 
Fair value of previously held equity interest   3,097 
Fair value of interest acquired through the June 2026 capital increase   6,423 
Total consideration attributable to SEALSQ   9,520 
Fair value of noncontrolling interests (“NCI”)   7,627 
Aggregate acquisition-date fair value, including NCI   17,147 

 

The amounts above are based on the implied Acquisition Date equity value derived from the June 2026 capital increase. The USD 6.4 million fair value of the newly acquired interest represents SEALSQ’s cash subscription in the capital increase at historical rate. The subscription cash was received by Wecan before the Acquisition Date and included in restricted cash in the Acquisition Date balance sheet, and it remained in restricted cash as of June 30,2026 when it was revalued. The acquired assets table below presents the gross acquisition-date balances recognized in consolidation. Noncontrolling interests were measured at fair value using the implied equity value and the applicable ownership percentage.

 

Immediately before the Acquisition Date, the Group remeasured its previously held equity interest in Wecan to its acquisition-date fair value of USD 3.1 million, resulting in a remeasurement loss of USD 320 thousand. Upon obtaining control, USD 51 thousand of accumulated other comprehensive income related to the previously held interest was reclassified to earnings, resulting in a net acquisition-date loss of USD 270 thousand. The remeasurement loss and related AOCI reclassification are presented in non-operating expense and non-operating income, respectively.

 

In connection with the acquisition, SEALSQ entered into a shareholders’ agreement that provides SEALSQ with an irrevocable call option to acquire all remaining shares of Wecan held by the noncontrolling shareholders. The option is exercisable solely at SEALSQ’s discretion beginning on the third anniversary of the Acquisition Date. The call option is an embedded feature of the noncontrolling interest and does not result in recognition of a separate derivative asset or liability or classification of the noncontrolling interest as redeemable equity.

 

The following table summarizes the preliminary allocation of the acquisition-date fair value as of June 1, 2026:

 

   USD’000 
Restricted cash   6,527 
Technology   4,062 
Trademarks   1,248 
Cash and cash equivalents   455 
Prepaid expenses and other current assets   286 
Crypto assets   71 
Accounts receivable   66 
Total assets acquired, excluding goodwill   12,715

Aggregate acquisition-date fair value, including NCI   17,147 

 

F-15

SEALSQ Corp Consolidated Financial Statements as of June 30, 2026

 

The acquisition-date amounts recognized are provisional because the Group has not completed its assessment of certain acquired assets and liabilities, including the valuation of acquired intangible assets, deferred revenue, employee benefit obligations, and the related deferred tax effects. The Group expects to finalize these valuations and the resulting goodwill within the measurement period, which will not exceed one year from the Acquisition Date. Measurement-period adjustments, if any, will be recognized retrospectively as of the Acquisition Date, with corresponding revisions to comparative information, as applicable.

 

Goodwill represents the excess of the aggregate acquisition-date fair value over the fair value of identifiable assets acquired and liabilities assumed. Goodwill is primarily attributable to the expected benefits from Wecan’s assembled workforce, future technology development, commercial expansion and other synergies that do not qualify for separate recognition as identifiable intangible assets. Goodwill has been allocated provisionally to the reporting unit included within the Group’s non-reportable segment. Goodwill is recorded in Wecan’s functional currency (CHF), is translated into USD at each reporting date in accordance with ASC 830.

 

Goodwill is not amortized and is tested for impairment at least annually, or more frequently if events or changes in circumstances indicate that it may be impaired, in accordance with ASC 350. No impairment indicators were identified as of June 30, 2026. Goodwill is not expected to be deductible for income tax purposes.

 

The acquired technology and trademarks are being amortized on a straight-line basis over preliminary estimated useful lives of 15 years. The weighted-average useful life of the acquired identifiable intangible assets is approximately 15 years.

 

   USD’000 
Technology   4,062 
Trademarks   1,248 
Acquired identifiable intangible assets   5,310 

 

For the period from June 1, 2026, through June 30, 2026, Wecan contributed revenue of USD 24,333 and net loss of USD 148,543 to the Group’s condensed consolidated results.

 

Supplemental Pro Forma Information (Unaudited)

 

The following unaudited pro forma consolidated financial information presents the combined results of SEALSQ and Wecan as if the acquisition had occurred on January 1, 2025:

 

   6 months ended June 30, 
USD’000  2026   2025 
Revenue   11,487    5,453 
Net income (loss)   (28,209)   (21,300)

 

The unaudited pro forma financial information includes adjustments to reflect incremental amortization of acquired identifiable intangible assets, related income tax effects, the acquisition-date remeasurement of the previously held equity interest, acquisition-related transaction costs and elimination of intercompany transactions. The pro forma financial information does not reflect potential synergies or integration costs and is not necessarily indicative of the results that would have occurred or of future results.

 

Note 7. Asset acquisition

 

On June 1, 2026, SEALSQ Corp acquired 100% of the outstanding shares of Miraex SA, a Swiss technology company focused on photonic integrated circuit technologies for quantum computing and quantum communications.

 

The Group evaluated the acquisition under ASC 805, Business Combinations, and elected to apply the optional concentration test. Approximately 92.9% of the fair value of the gross assets acquired was concentrated in Miraex’ proprietary Thin Film Lithium Tantalate photonic integrated circuit technology. Accordingly, substantially all of the fair value of the gross assets acquired was concentrated in a single identifiable asset or group of similar identifiable assets, the acquired set did not meet the definition of a business, and the transaction was accounted for as an asset acquisition in line with ASC 805.

 

The total acquisition cost was USD 5.8 million (CHF 4.6 million) and consisted of the following components:

 

   USD’000 
Base purchase price   5,046 
Amounts paid to third-party convertible-loan holders   724 
Direct transaction costs   75 
Total acquisition cost paid in cash   5,845 

 

Direct transaction costs were capitalized as part of the cost of the asset acquisition. The Group’s CHF 0.5 million pre-closing convertible loan entered into on March 24, 2026, with Miraex, which was applied toward SEALSQ’s capital subscription at closing but was not included in the above base purchase price, and a separate CHF 0.5 million capital contribution to fund Miraex’ operations and development were accounted for as separate shareholder capital transactions and were not included in acquisition cost.

SEALSQ Corp Consolidated Financial Statements as of June 30, 2026

 

The following table summarizes the allocation of acquisition cost as of June 1, 2026:

 

   USD’000 
Acquired technology   7,524 
Property, plant and equipment   261 
Cash and cash equivalents   254 
Inventory   118 
Other receivables   81

Total assets acquired   8,294 
Deferred income tax liability   (1,128)
Financial liabilities   (765)
Pension liabilities   (270)
Accounts payable   (161)
Other liabilities   (125)
Total liabilities assumed   (2,449)
Net assets acquired / total acquisition cost   5,845 

 

The acquisition cost was allocated to the assets acquired and liabilities assumed based on their relative fair values, subject to the requirements of other applicable US GAAP. The principal asset recognized was acquired technology with an initial carrying amount of USD 7.5 million (CHF 5.9 million). A deferred income tax liability of USD 1.1 million (CHF 0.9 million) was recognized in connection with the acquired technology. Because the transaction was accounted for as an asset acquisition, no goodwill was recognized.

 

The acquired technology is being amortized on a straight-line basis over its estimated useful life of 14.6 years. Amortization commenced on June 1, 2026.

 

Note 8. Fair value measurements

 

ASC 820 establishes a three-tier fair value hierarchy for measuring financial instruments, which prioritizes the inputs used in measuring fair value. These tiers include:

 

Level 1, defined as observable inputs such as quoted prices in active markets;

 

Level 2, defined as inputs other than quoted prices in active markets that are either directly or indirectly observable; and

 

Level 3, defined as unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions.

 

   As of June 30, 2026   As of December 31, 2025   Fair     
USD’000  Carrying amount   Fair

   Carrying amount   Fair

Investment, current   2,449    2,449    10,032    10,032    2    12 

 

In addition to the methods and assumptions we use to record the fair value of financial instruments as discussed in the Fair Value Measurements section above, we used the following methods and assumptions to estimate the fair value of our financial instruments:

 

-Available-for-sale debt securities, noncurrent - fair value remeasured as of reporting period, based on information available.

 

-Investment, current – consists of a managed investment account held with UBS Switzerland AG. Although the account is made up of a diversified, actively managed portfolio, including publicly traded equity securities, investment funds and exchange-traded funds, fixed-income instruments, structured products, and fiduciary call deposits and short-term cash balances, with fair value levels ranging from Level 1 to Level 3, fair value is remeasured as of reporting period, based on the statement of assets made available by UBS at the reporting date, which falls under Level 2.

 

The carrying amounts of accounts receivable, accounts payable, notes payable, and indebtedness to related parties approximate their fair values due to the short-term nature of these instruments. The carrying amount of bonds, mortgages and other long-term debt approximates fair value as the underlying interest rates are consistent with current market rates. These financial instruments are not measured at fair value on a recurring or nonrecurring basis and are accordingly not included in the fair value hierarchy table above; the fair value information above is provided solely in accordance with ASC 825-10-50-10.

 

Investments in SAFEs and equity securities without a readily determinable fair value are accounted for under the measurement alternative in ASC 321 (cost minus impairment) and are therefore not fair value measurements; see Note 23 for the related carrying amounts and impairment assessment.

Note 12. Investment, current

 

Managed Investment Account

 

In November 2025, the Group entered into a discretionary asset management arrangement with UBS Switzerland AG (“UBS”) and opened an investment account under the UBS “Manage Premium” mandate (the “UBS Investment Account). Under the terms of the arrangement, UBS is authorized to manage the assets held in the UBS Investment Account on a discretionary basis within agreed investment parameters. The UBS Investment Account is maintained for investment purposes and not for day-to-day operating cash needs.

 

The UBS Investment Account consists of a diversified, actively managed portfolio, including publicly traded equity securities, investment funds and exchange-traded funds, fixed-income instruments, structured products, and fiduciary call deposits and short-term cash balances held to facilitate portfolio management.

 

The UBS Investment Account is classified as current investments and is measured at fair value at each reporting date. Changes in fair value, including unrealized gains and losses, are recognized in earnings. Fair value is determined based on UBS account statements reflecting observable market prices for the underlying investments.

 

Cash balances and call deposits held within the UBS Investment Account are not segregated or designated for operating use and are maintained as part of the overall investment strategy. Accordingly, such balances are not classified as cash or cash equivalents

 

Note 13. Government assistance

 

SEALSQ France SAS and IC’Alps SAS are eligible for research tax credits provided by the French government. As of June 30, 2026 and December 31, 2025, the receivable balances in respect of these research tax credits owed to the Group were respectively USD 6,613,247 and USD 4,578,813, each translated at the period-end exchange rate.

 

F-18

SEALSQ Corp Consolidated Financial Statements as of June 30, 2026

 

The credit is deductible from the entity’s income tax charge for the year or payable in cash the following year, whichever event occurs first. Refundable R&D tax credits are accounted for as government assistance in accordance with ASC 832 and are recognized in the consolidated financial statements consistent with the Group’s accounting policy.

 

In addition, the Companies are also entitled to receive other grants, including interest subvention—a government incentive that subsidizes or reduces the interest cost on eligible borrowings (see Note 28 for further details)—as well as reimbursements for certain expenses.

 

Note 14. Other current assets

 

Other current assets consisted of the following:

 

USD’000  As of

Management evaluated the acquired identifiable intangible assets and other long-lived assets under ASC 360 and concluded that the asset group was recoverable, and no impairment loss was required as of June 30, 2026.

 

At December 31, 2025, the Group held 195,788,312 WECAN utility tokens received through token purchase and service arrangements with Wecan. Because Wecan was a related party, the WECAN tokens were outside the scope of ASC 350-60 and were accounted for as indefinite-lived intangible assets under ASC 350-30 using a cost-less-impairment model.

 

Immediately prior to obtaining control of Wecan on June 1, 2026, the carrying amount of the WECAN tokens was USD 561,377. Based on observable market pricing at May 31, 2026, the Group recognized an impairment loss of USD 322,668, reducing the carrying amount to USD 238,709.Upon consolidation of Wecan on June 1, 2026, the remaining USD 238,709 carrying amount was derecognized because WECAN is issued by a consolidated subsidiary and no corresponding obligation was recognized within Wecan. Accordingly, the consolidated carrying amount of WECAN tokens was nil at June 30, 2026.

 

The Group continues to track the underlying WECAN token quantities notwithstanding the nil carrying amount at June 30, 2026. Any subsequent external transfer or disposal will be accounted for based on the terms and substance of the transaction.

 

At June 30, 2026, the Group held 65,412 USDC tokens through Wecan’s Uniswap liquidity arrangement. The USDC tokens were owned and withdrawable by Wecan and had a fair value of USD 65,412 at June 30, 2026. The remaining USD 16,214 included within crypto assets and related balances relates to a market-maker receivable.

 

As of June 30, 2026, a balance of USD 2,786,454 of license fees was outstanding in line with agreed payment terms, made up of USD 1,906,039 payable in the next 12 months recorded in accounts payable and USD 880,415 payable in long-term recorded in other noncurrent liabilities on the consolidated balance sheet.

 

The useful economic life of intangible assets is as follows:

 

Technology 15 years

 

Trademarks 9 to 15 years

 

Patents 5 to 10 years

 

License agreements 1 to 3 years

 

Customer relationships 19 years

 

Other intangibles 2 to 9 years

Note 18. Leases

 

The Group has historically entered into a number of lease arrangements under which it is the lessee. As of June 30, 2026, the SEALSQ Group holds six operating leases which relate to premises.

 

We do not sublease. All our operating leases include multiple optional renewal periods which are not reasonably certain to be exercised.

 

As of June 30, 2026, the Group holds five finance leases relating to IT equipment. During the six months ended June 30, 2026, the Group completed one sale and leaseback transaction relating to IT equipment. The transaction met the criteria for a sale under ASC 606, and, accordingly, the Group derecognized the assets sold and recognized a right-of-use asset and lease liability in accordance with ASC 842. The leaseback arrangements are classified as finance leases.

 

During the six months ended June 30, 2026 and 2025, we recognized rent expenses associated with our leases as follows:

Total lease liabilities   5,889    6,320 

 

As of June 30, 2026, future minimum annual lease payments were as follows.

Less effects of discounting   (817)   (45)   (862)
Lease liabilities recognized   5,799    90    5,889 

 

As of June 30, 2026 the weighted-average remaining lease term was 7.50 years for operating leases and 2.90 years for finance leases.

 

As leases do not provide an implicit rate, we calculated an estimate rate based upon the estimated incremental borrowing rate of the Group. The weighted average discount rate associated with operating lease as of June 30, 2026 was 3.71%. The weighted average discount rate associated with finance lease as of June 30, 2026 was 2.92%.

 

Note 19. Goodwill

 

The Group performs its annual goodwill impairment test on October 1 of each year, or more frequently if events or changes in circumstances indicate that goodwill may be impaired. Under the quantitative test, the fair value of each reporting unit is compared with its carrying amount, including goodwill. If the carrying amount exceeds the reporting unit’s fair value, an impairment charge is recognized in an amount equal to the excess, limited to the total amount of goodwill allocated to that reporting unit.

 

On August 4, 2025, the Group acquired 100% of IC’Alps SAS. In connection with the acquisition, goodwill of EUR 4,815,338 was recognized as part of the purchase price allocation under ASC 805. On June 1, 2026, the Group acquired control of Wecan and goodwill of CHF 4,849,470 was recognized in connection with the acquisition, as further described in Note 6. Business Combinations.

 

In the ASIC segment, the goodwill relates to the acquisition of IC’Alps, which represents the reporting unit for purposes of goodwill impairment testing. During the six months ended June 30, 2026, management reviewed IC’Alps’ performance against budget as part of its interim goodwill impairment assessment. Based on this assessment, including current project activity and the longer-term business outlook, management concluded that a quantitative goodwill impairment test was not required, and no impairment loss was recognized as of June 30, 2026. The Group’s next annual goodwill impairment test will be performed as of October 1, 2026.

 

Goodwill arising from the Wecan acquisition is included within the Group’s non-reportable segment. Management evaluated whether any events or changes in circumstances through June 30, 2026, indicated that the goodwill may be impaired. No such indicators were identified, and no impairment loss was recognized as of June 30, 2026.

 

IC’Alps’ functional currency is the Euro (EUR) and Wecan’s functional currency is the Swiss Franc (CHF). Accordingly, goodwill recognized in connection with these acquisitions was recorded in the respective functional currencies and is translated into the Group’s reporting currency (USD) at each reporting date in accordance with ASC 830. Translation adjustments are recorded in accumulated other comprehensive income and do not impact net income.

The assessment of goodwill impairment requires judgment, including the evaluation of qualitative factors such as operating performance, projected cash flows, industry and market conditions, and other relevant events and circumstances. Changes in these factors could result in future impairment charges.

Note 21. Investments in unconsolidated affiliates

 

Quantix Edge Security S.L.

 

On September 11, 2025, SEALSQ made a EUR 0.75 million capital contribution to Quantix Edge Security S.L. (“Quantix”), a Spanish joint venture, and acquired a 5.0% ownership interest. SEALSQ determined that it does not control Quantix but has the ability to exercise significant influence. Accordingly, the investment is accounted for under the equity method of accounting. The investment was initially recorded at cost. No material basis differences requiring amortization were identified at the acquisition date.

 

Quantix was in a pre-operational stage as of June 30, 2026, and an equity method loss of USD 41,959 was recognized for the six months ended June 30, 2026. As of June 30, 2026, the carrying amount of the investment was USD 835,776 and no impairment indicators were identified.

 

Management evaluated the significance of Quantix under Rule 1-02(w) of Regulation S-X as of and for the six months ended June 30, 2026. None of the applicable thresholds exceeded 20%. Accordingly, summarized financial information is not required.

 

Note 22. Investments in unconsolidated related party affiliates

 

WISeSat.Space Corp

 

On November 6, 2025, the Group invested USD 10.0 million in WISeSat.Space Corp (“WISeSat Corp”) and acquired 870 shares, representing an 8.08% ownership interest; the remaining ownership interest is held by WISeKey. The Group determined that it does not control WISeSat Corp but has the ability to exercise significant influence. Accordingly, the investment is accounted for under the equity method. Because the Group and WISeSat Corp are under the common control of WISeKey, the investment is presented as an investment in an unconsolidated related-party affiliate. The investment was initially recorded at cost, and no material basis differences requiring amortization were identified.

 

F-23

SEALSQ Corp Consolidated Financial Statements as of June 30, 2026

 

For the six months ended June 30, 2026, the Group recognized an equity method loss of USD 340,817. As of June 30, 2026, the carrying amount of the investment was USD 9,617,266 and no impairment indicators were identified.

 

Management evaluated the significance of WISeSat Corp under Rule 1-02(w) of Regulation S-X as of and for the six months ended June 30, 2026. None of the applicable thresholds exceeded 20%. Accordingly, summarized financial information is not required.

 

Note 23. Other investments

 

Investment in SAFE

 

On December 4, 2025, February 16, 2026, and May 25, 2026, the Group entered into Simple Agreements for Future Equity (“SAFEs”, and individually, “SAFE”) with EeroQ Corporation (“EeroQ”), a privately held U.S.-based quantum computing company. The investments do not convey equity ownership, voting rights, or significant influence at inception.

 

The Group invested an aggregate of USD 7.0 million under the SAFEs, consisting of an initial investment of USD 1.0 million in December 2025, USD 1.0 million in February 2026, and a further investment of USD 5.0 million in May 2026.

 

The SAFEs provide the Group with contractual rights to receive equity interests or cash upon the occurrence of specified future events, including qualifying equity financing, liquidity events, or dissolution events.

 

The investments are measured at cost less impairment as they do not have a readily determinable fair value. The Group evaluates the investments for impairment and observable price changes in orderly transactions for identical or similar investments of the same issuer at each reporting date.

 

As of June 30, 2026, the carrying amount of the SAFE investments was USD 7.0 million. Management concluded that no impairment indicators or observable price changes requiring adjustment were identified during the period.

 

Investment in equity securities

 

On May 26, 2026, SEALSQ acquired 16,666 Series A preferred shares of Quobly SAS (“Quobly”), a French quantum computing company developing silicon-based quantum processors, together with attached anti-dilution warrants, for an aggregate consideration of EUR 14,999,400. The investment represents approximately 7.4% ownership of Quobly on a non-diluted basis and is accounted for as an investment in equity securities under ASC 321. As Quobly is a privately held company and the investment does not have a readily determinable fair value, the investment is measured using the measurement alternative and is recorded at cost, less impairment, and adjusted for observable price changes in orderly transactions for identical or similar investments of the same issuer.

 

As of June 30, 2026, the carrying amount of the investment was USD 17,453,872 (EUR 14,999,400) and management concluded that no impairment indicators or observable price changes requiring adjustment existed.

 

In connection with the investment, SEALSQ entered into a five-year Joint Cooperation Agreement with Quobly to provide EUR 5.0 million of future orders and annual prepayments of EUR 1.0 million. The initial prepayment for the first year was recognized under accounts receivable from other related parties and customer contract liability, current, as of June 30, 2026. Refer to Note 41 for the related-party disclosure.

Note 29. Indebtedness to related parties

 

On April 1 and October 1, 2019, the SEALSQ Group entered into loan agreements with WISeCoin AG, an affiliate of WISeKey, for, respectively. EUR 250,000 (the “WISeCoin Euro Loan”) and USD 2,750,000 (the “WISeCoin USD Loan”) (together, the “WISeCoin Loans”). The WISeCoin Loans bear interest at 3% per annum, amended to 2.5% on November 3, 2022, and have no maturity date.

 

On April 1, 2021, the Group entered into a Debt Remission Agreement (the “Debt Remission”) with WISeKey pursuant to which EUR 5 million (USD 5,871,714 at historical rate) of outstanding indebtedness was remitted without compensation. Under the terms of the Debt Remission, WISeKey retained the right to reinstate the debt and require repayment in fiscal years in which SEALSQ France SAS achieves positive income before income tax expense. Accordingly, the amount subject to the Debt Remission continued to be recognized as a noncurrent related-party liability and was revalued at each period end at the applicable closing rate. On December 20, 2023, WISeKey agreed to write off EUR 2 million (USD 2,191,282 at historical rate), leaving EUR 3 million (USD 3,105,300) outstanding.

 

In 2025, the Group repaid in full the outstanding EUR 3 million Debt Remission as well as the WISeCoin USD Loan principal in an amount of USD 2,750,000 and interest thereon of USD 403,420. The WISeCoin Euro Loan and interest thereon remained outstanding for a total amount of USD 305,700 as of December 31, 2025.

 

As of December 31, 2025, the Group owed WISeKey and its affiliates USD 2,180,054 in current payables corresponding to the WISeCoin Euro Loan, unpaid interest and management fees, and had a current receivable of USD 8,656,171 from WISeKey corresponding to management fees and advances.

 

As of June 30, 2026, the Group owed WISeKey and its affiliates USD 1,967,370 in current payables corresponding to the WISeCoin Euro Loan, unpaid interest and management fees. The WISeCoin Euro Loan and interest thereon remain outstanding and classified as current, for a total amount of USD 340,097 as of June 30, 2026.

 

As of June 30, 2026, the Group also had a current receivable of USD 16,672,411 from WISeKey and its affiliates corresponding to management fees and advances.

 

Note 30. Employee benefit plans

 

Defined benefit post-retirement plan

 

The Group maintains five pension plans: one maintained by each of SEALSQ Corp, Wecan and Miraex covering their employees in Switzerland, one maintained by SEALSQ France SAS and one maintained by IC’Alps SAS, both covering their employees in France.

 

All plans are considered defined benefit plans and accounted for in accordance with ASC 715 Compensation – Retirement Benefits. This model allocates pension costs over the service period of employees in the plan. The underlying principle is that employees render services ratably over this period, and therefore, the income statement effects of pensions should follow a similar pattern. ASC 715 requires recognition of the funded status or difference between the fair value of plan assets and the projected benefit obligations of the pension plan on the balance sheet, with a corresponding adjustment recorded in the net loss. If the projected benefit obligation exceeds the fair value of the plan assets, then that difference or unfunded status represents the pension liability.

 

F-27

SEALSQ Corp Consolidated Financial Statements as of June 30, 2026

 

The Group records net service cost as an operating expense and other components of defined benefit plans as a non-operating expense in the statement of comprehensive loss.

 

The liabilities and annual income or expense of the pension plan are determined using methodologies that involve several actuarial assumptions, the most significant of which are the discount rate and the long-term rate of asset return (based on the market-related value of assets). The fair value of plan assets is determined based on prevailing market prices.

 

The defined benefit pension plan maintained by SEALSQ France SAS and IC’Alps SAS, and their obligations to employees in terms of retirement benefits, is limited to a lump sum payment based on remuneration and length of service, determined for each employee. The plan is not funded, which means that there are no plan assets.

 

The pension liability calculated as of June 30, 2026 for SEALSQ Corp, SEALSQ France SAS and IC’Alps SAS is based on annual personnel costs and assumptions as of December 31, 2025. The pension liability calculated as of June 30, 2026 for Wecan and Miraex is based on annual personnel costs and assumptions as of May 31, 2026.

 

The expected future cash flows to be paid by the Group for employer contribution for the year ended December 31, 2026 are approximately USD 211,000.

Note 31. Commitments and contingencies

 

Lease commitments

 

The future payments due under leases are shown in Note 18.

 

Warranties and indemnifications

 

The Group’s product and service sales agreements are evaluated under ASC 606 and ASC 460 to determine whether a warranty is an assurance-type warranty (accounted for under ASC 460) or a service-type warranty that represents a separate performance obligation under ASC 606. All of the warranties described below are assurance-type: none provide the customer with a service beyond assurance that the related product or service will perform in accordance with its agreed-upon specifications, and none give rise to a separate performance obligation.

 

Certain of the Group’s sales agreements also include provisions indemnifying customers against liabilities arising from an infringement of a third party’s intellectual property rights, or from a breach of confidentiality or service-level requirements. It is not possible to determine the maximum potential amount payable under these indemnification agreements, given the Group’s lack of history of indemnification claims and the unique facts and circumstances of each agreement. To date, the Group has not incurred any costs, and has not recognized any liability, related to these indemnification obligations.

 

The Group also provides assurance-type warranties on its ASIC products, with the warranty period and remedy varying by the stage of the product life cycle at which the circuit is delivered. During the development phase (prototypes and pre-series chips), the warranty period is three to six months from the date of delivery. Once a circuit has reached volume production (delivered as a processed, unpackaged semiconductor chip or as a processed wafer), the warranty period is 24 months from the date of delivery, and available remedies include replacement of the product, a credit note, or a rebate on the purchase price.

 

In both cases, the customer may request that the Group initiate a diagnostic process to assess a potential defect. If the process determines the circuit conforms to specifications — excluding third-party IP or sub-blocks, and except where the customer has modified the product — or if the customer cancels the process before completion, the customer bears the cost of that process. The cost of any redesign outside the scope of the warranty, or of support requested after the warranty period has expired, is chargeable to the customer at cost or at agreed rates. The warranty excludes damage not attributable to the Group, such as damage resulting from improper storage or use by the customer.

 

In accordance with ASC 460, the Group has classified all of the warranties described above as assurance-type warranties, because each covers only the relevant product’s or service’s compliance with its agreed-upon specifications. No liability has been recognized for potential warranty claims under any of these warranties, as the Group cannot reasonably estimate the likelihood or amount of future payments. It is not possible to determine the maximum potential amount under these indemnification agreements due to our lack of history of prior indemnification claims and the unique facts and circumstances involved in each particular agreement. To date, we have not incurred any costs as a result of such indemnifications and have not accrued any liabilities related to such obligations in our consolidated financial statements.

Each F share confers upon the shareholder the following rights: the right to attend any meeting of shareholders; a number of votes per F share, on any matter that is submitted to a vote of shareholders, that would cause the total votes of all F shares to equal 49.99% of the voting power of all shares (or, if the applicable voting standard is “a majority of the shares present in person or represented by proxy and entitled to vote on such matter”, 49.999999% of the voting power of shares present in person or represented by proxy and entitled to vote on such matter); the right to an equal share in any dividend paid by SEALSQ against each other F share, which shall be five times greater than any amount paid by SEALSQ against each ordinary share but which shall not rank in preference to any other share; and the right to an equal share in the distribution of the surplus assets of SEALSQ against each other F share, which shall be five times greater than any amount paid by SEALSQ against each ordinary share but which shall not rank in preference to any other share.

 

The F shares are subject to mandatory and automatic redemption, in the event of a change of control (being the acquisition by any person or entity, alone or jointly, of more than 50% of the voting rights of any F shareholder which is a corporate entity), as determined by SEALSQ’s board of directors, in exchange for the issuance of new ordinary shares at a ratio of five (5) ordinary shares for each one (1) F share redeemed. The F shares are non-transferable

 

Equity transactions

 

At-the-Market Facility

 

On May 19, 2025, SEALSQ entered into an at-the-market (“ATM”) equity offering program pursuant to which it may offer and sell ordinary shares having an aggregate offering price of up to USD 100 million from time to time through a designated sales agent.

 

During the six months ended June 30, 2026, the Group did not sell any ordinary shares under the ATM program. As of June 30, 2026, approximately USD 28.9 million remained available for future sales under the ATM facility.

 

Share Purchase Agreement with Several Institutional Investors signed in March 2026

 

On March 15, 2026, the Group entered into a Securities Purchase Agreement (the “March 2026 SPA”) with several institutional investors in connection with a registered direct offering led by Maxim Group LLC. Pursuant to the March 2026 SPA, the Group agreed to sell and issue 22,913,630 ordinary shares and pre-funded ordinary share purchase warrants to purchase up to 7,500,000 ordinary shares (the “Pre-funded Warrants”), together with Class E ordinary share purchase warrants to purchase up to 60,827,260 ordinary shares (the “Class E Warrants”), for aggregate gross proceeds of USD 124,999,269.

 

Each Pre-funded Warrant is exercisable for one ordinary share at an exercise price of USD 0.0001 per share and is immediately exercisable until exercised in full. The Class E Warrants are immediately exercisable, have an exercise price of USD 5.50 per ordinary share, and expire seven years from the date of issuance. Each Class E Warrant is exercisable for one ordinary share.

 

F-29

SEALSQ Corp Consolidated Financial Statements as of June 30, 2026

 

The ordinary shares, Pre-funded Warrants, and Class E Warrants issued in connection with the March 2026 SPA were assessed as equity instruments and recorded within stockholders’ equity in accordance with ASC 480 and ASC 815. The gross proceeds from the transaction were allocated among the ordinary shares and the Pre-Funded Warrants and Class E Warrants based on their relative fair values at the issuance date, with the amounts allocated to ordinary shares recorded in the Common stock - Ordinary shares at par value and the excess credited to APIC, and the amounts allocated to the Pre-Funded Warrants and Class E Warrants recorded in APIC. The fair value of the ordinary shares was determined based on the quoted market price on the issuance date and the fair value of the Pre-Funded Warrants and Class E Warrants was estimated using a Black-Scholes option pricing model.

 

Issuance costs directly attributable to the transaction of USD 7,775,329 were recorded as a reduction of stockholders’ equity and allocated to the ordinary shares and the Pre-Funded Warrants and Class E Warrants on the same relative fair value basis. All pre-funded warrants were exercised as of June 30, 2026, resulting in the issuance of 7,500,000 ordinary shares.

 

Note 33. Revenue

 

Nature of goods and services

 

The Group generates revenues from the sale of semiconductors secure chips and from Digital Certificates, Software as a Service, Software license and Post-Contract Customer Support (PCS) for cybersecurity applications. Products and services are sold principally separately but may also be sold in bundled packages.

 

The Group also generates revenues by delivering custom ASIC (Application-Specific Integrated Circuit) design and development services during the pre-production phase, and by supplying manufactured ASIC chips during the production phase. These services and products are typically contracted separately but may also be bundled across multiple phases of the ASIC lifecycle.

 

For bundled packages, the Group accounts for individual products and services separately if they are distinct – i.e. if a product or service is separately identified from other items in the bundled package and if a customer can benefit from it. The consideration is allocated between separate products and services in a bundle based on their stand-alone selling prices. The stand-alone selling prices are determined based on the list prices when available or estimated based on the Adjusted Market Assessment approach (e.g. licenses), or the Expected Cost-Plus Margin approach (e.g., PCS).

 

The following is a description of the principal activities from which the Group generates its revenue across all reportable segments.

 

Product and services   Nature, timing of satisfaction of performance obligations and significant payment terms
Semiconductors secure chips  

Although they may be sold in connection with other services of the Group, they always represent distinct performance obligations.

 

The Group recognizes revenue when a customer takes possession of the chips, which usually occurs when the goods are delivered. Customers typically pay once goods are delivered.

     
SaaS  

The Group’s SaaS arrangements cover the provision of cloud-based certificates for authentication purposes such as Device Attestation Certificates (DACs) for MATTER Protocol, IoT Device-to-Cloud Authentication, or Device-to-Device Authentication. The Group recognizes revenue on a straight-line basis over the service period which is usually yearly renewable.

 

Where lifelong certificates are issued, the Group recognizes revenue when the certificate is delivered and usable by the customer.

 

Customers usually pay ahead of the service period; the paid amounts which have not yet been recognized as revenue are shown as deferred revenue on the balance sheet.

     
Software and INeS Certificate Management Platform  

The Group provides software for certificates life-cycle management and signing and authentication solutions through its INeS Certificate Management Platform. The Group recognizes revenue when the software has been delivered or the platform has been set up, and PCS revenue over the service period which is usually one-year renewable.

 

Customers pay upon delivery of the software or over the PCS.

     
Implementation, integration and other services   The Group provides services to implement and integrate multi-element cybersecurity solutions. Most of the time the solution elements are off-the-shelve non-customized components which represent distinct performance obligations. Implementation and integration services are payable when rendered, while other revenue elements are payable and recognized as per their specific description in this section.
     
ASIC Design   The services provided are structured into Work Packages (WPs), each representing a separate performance obligation. These could include services associated with the specification/ pre-study, design, prototyping or industrialization. Revenue is recognized over time using the cost-incurred method, as customers control the asset during development and the Group has a right to payment for performance to date. Payments are made progressively based on milestones and deliverables.
     
ASIC Production   Each purchase order for ASIC chips represents a distinct performance obligation to provide the specified quantity and type of chips. Revenue is recognized at a point in time, specifically, when control of the chip transfers to the customer upon delivery. The Company acts as principal, managing the full production process including subcontractor coordination, quality assurance, and logistics. Customers typically pay once goods are delivered.

F-32

SEALSQ Corp Consolidated Financial Statements as of June 30, 2026

 

The options granted were valued at grant date using the Black-Scholes model.

 

There was no grant of options on F Shares in the six months ended June 30, 2026.

 

Stock option charge to the income statement

 

The Group calculates the fair value of options granted by applying the Black-Scholes option pricing model, using the market price of an Ordinary Share of SEALSQ. Expected volatility is based on historical volatility of SEALSQ’s Ordinary Shares.

 

In the six months ended June 30, 2026, a total charge of USD 3,969,010 for options granted to Board members, employees and external advisors was recognized in the consolidated income statement calculated by applying the Black-Scholes model at grant, in relation to options.

 

An amount of USD 4,247,067 was in relation to equity classified options whilst the remaining USD (278,057) related to liability classified stock options.

 

The following assumptions were used to calculate the compensation expense and the calculated fair value of stock options granted:

Note 38. Segment reporting

 

The Group has two operating and reportable segments that meet the criteria set forth in ASC 280-10-50: Semiconductors and ASIC.

 

Following the acquisition of IC’Alps on August 4, 2025, the Group updated its reportable segments to reflect changes in its internal management reporting structure. Prior to the acquisition of IC’Alps, the Group’s operations were primarily composed of the Semiconductors business and corporate activities. Corporate activities are now included within “Other profit or loss.” Prior period segment information has been recast to conform to the current year presentation.

 

The Group’s Chief Executive Officer, who is the Chief Operating Decision Maker, evaluates segment performance and allocates resources based on net sales, gross profit (where applicable), and operating income or loss. In making these decisions, the Chief Operating Decision Maker considers budgets, budget-to-actual variances, and key operating metrics, and allocates resources, including employees, property, plant and equipment, and financial resources, across the reportable segments.

 

Both the Semiconductors and ASIC reportable segments are strategic business units that offer distinct products and services and are managed separately because they require dedicated resources and targeted marketing strategies. The Semiconductors segment encompasses the design, manufacturing, sales and distribution of high-end, Common Criteria EAL5+ & FIPS 140-3-certified secure microprocessors. The ASIC segment’s operations include a complete offering for Application Specific Integrated Circuits (ASIC) and Systems on Chip (SoC) development from circuit specification, mastering design in-house, up to qualification and the management of the entire production supply chain. The ASIC reportable segment did not exist prior to August 4, 2025, when SEALSQ acquired IC’Alps.

 

The accounting policies of the segments are consistent with those described in the summary of significant accounting policies of the Group. Segment operating income includes directly attributable revenues and expenses. “Other segment items” include corporate expenses and other non-operating items that are not allocated to the reportable segments.

 

The Group accounts for intersegment sales and transfers as if the sales or transfers were to third parties, that is, at current market prices.

WISeSat.Space Subscription Agreement and De-SPAC Timeline Extension

 

On August 6, 2026, the Group entered into a Subscription Agreement with WISeSat.Space Holdings Corp., the entity that will become the publicly listed parent of WISeSat.Space Corp. upon completion of its previously announced business combination with Columbus Acquisition Corp. (Nasdaq: COLA), under which the Group committed to purchase USD 10 million of WISeSat.Space Holdings Corp. ordinary shares in a private placement. The purchase price per share will equal the redemption price paid to Columbus Acquisition Corp.’s public shareholders who elect to redeem their shares in connection with the business combination. Based on an assumed redemption price of approximately USD 10.66 as of June 30, 2026, the commitment would result in the issuance of approximately 938,086 shares. The subscription is conditioned on, and will close concurrently with, the closing of the business combination. As of the date of this report, the Group has not advanced any funds or recognized any asset in connection with this commitment. The date for completion of the business combination is expected to be on or before October 31, 2026.

 

Note 43. Impacts of ongoing conflicts and regulatory changes

 

Impacts of the war in Ukraine

 

Following the outbreak of the war in Ukraine in late February 2022, several countries imposed sanctions on Russia, Belarus and certain regions in Ukraine. There has been an abrupt change in the geopolitical situation, with significant uncertainty about the duration of the conflict, changing scope of sanctions and retaliation actions including new laws.

 

The SEALSQ group does not have any operation or customer in Russia, Belarus or Ukraine, and, as such, does not foresee any direct impact of the war on its operations. However, the war has also contributed to an increase in volatility in currency markets, energy prices, raw materials and other input costs, which may impact the Group’s supply chain in the future.

 

As of June 30, 2026, SEALSQ assessed the consequences of the war for its financial disclosures, including impacts on key judgments and significant estimates, and concluded that no changes were required. SEALSQ will continue to monitor these areas of increased risk for material changes.

 

Impacts of the Israel–Hamas and U.S./Israel–Iran conflicts

 

Israel’s declaration of war on Hamas in October 2023 has degraded the geopolitical environment in the region and created uncertainty. On February 28, 2026, the U.S. and Israel launched coordinated strikes against Iran: Iran’s retaliation attacks expanded the conflict beyond just Iran and Israel and have threatened some commercial routes, especially traffic through the Strait of Hormuz.

 

The SEALSQ group does not have any operation or customer in that region, and, as such, does not foresee any direct impact of these conflicts on its operations. SEALSQ’s supply chain is not dependent on commercial routes through and around the Strait of Hormuz. However, depending on their duration and intensity, these conflicts may adversely affect the global economy, financial markets and the Group’s supply chain in the future.

 

As of June 30, 2026, and as of the filing date, SEALSQ assessed the consequences of the war for its financial disclosures and considered the impacts on key judgments and significant estimates, and concluded that no changes were required. SEALSQ will continue to monitor these areas of increased risk for material changes.

SEALSQ Corp Consolidated Financial Statements as of June 30, 2026

 

Our business could suffer as a result of tariffs and trade sanctions or similar actions

 

The imposition by the United States of tariffs, sanctions or other restrictions on goods exported from the United States or imported into the United States, or countermeasures imposed in response to such government actions, could adversely affect our operations or our ability to sell our products globally, which could adversely affect our operating results and financial condition. Over the course of 2025 and 2026, U.S. tariff policy has continued to escalate and has proven highly volatile: the U.S. government has imposed a series of new tariffs on goods imported into the United States, courts have invalidated several of them, the administration has responded with successive replacement measures, and non-U.S. governments have responded with their own countermeasures, export controls, and legal challenges.

 

For example, in January 2026, the United States imposed a 25% tariff under Section 232 of the Trade Expansion Act of 1962 on imports of certain high-performance semiconductor products and derivative parts meeting specified computing-performance and memory-bandwidth thresholds (a category most associated with advanced graphics processing units and AI accelerators), subject to a number of end-use exemptions, including for U.S. data center, research and development, startup, consumer-electronics, industrial, and public-sector uses. This tariff is narrower in scope than the tariff on “all semiconductor chips” the administration had initially proposed in February 2025, but the U.S. Department of Commerce has reserved the right to broaden its scope to additional semiconductor categories following a mid-2026 review. Separately, in February 2026, the U.S. Supreme Court held that the International Emergency Economic Powers Act does not authorize the broad “reciprocal” tariffs the administration had imposed on imports from most U.S. trading partners, and those tariffs have since been invalidated. The administration responded by imposing a new 10% tariff under Section 122 of the Trade Act of 1974 on substantially all imports, which a U.S. trade court likewise found to exceed the government’s statutory authority in May 2026; that tariff expired by its own statutory time limit in July 2026 and has since been followed by new Section 301 tariff actions tied to separate manufacturing-overcapacity and forced-labor investigations covering dozens of countries. As a result of this rapid succession of new tariffs, court rulings, and replacement measures, the future of U.S. tariff policy, and the possibility of further new tariffs and countermeasures, remains highly uncertain.

 

Although a large amount of our supply chain does not currently directly import products to the United States as we supply to contract manufacturers outside the United States, there is a possibility that any future tariffs may still impact upon our ability to sell our products and to remain competitive in the market. Such escalations in these trade measures may directly impair our business by increasing trade-related costs or disrupting established supply chains and may indirectly impair our business by causing a negative effect on global economic conditions and financial markets. The ultimate impact of these trade measures is uncertain and may be affected by various factors, including whether and when such trade measures are implemented, the timing when such measures may become effective, and the amount, scope, or nature of such trade measures.

 

As of June 30, 2026, SEALSQ assessed the impact of these uncertainties for its financial disclosures and considered the impacts on key judgments and significant estimates, and concluded that no changes were required. SEALSQ will continue to monitor these areas of increased risk for material changes.
