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 April 30, 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.

Additional paid-in capital
During preparation of the Group’s 2025 financial statements, management identified an error in the accounting for Swiss issuance stamp duties arising on share issuances by the Group’s consolidated subsidiary SEALSQ Corp. The error resulted in an understatement of consolidated liabilities and additional paid-in capital, and an overstatement of the loss and noncontrolling interest associated with SEALSQ share issuances. Management evaluated the error in accordance with ASC 250 and applicable SEC materiality guidance and concluded that the previously issued consolidated financial statements were not materially misstated. The Group revised the comparative information presented herein to correct the immaterial error.
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.

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.
Business Combinations
The Group accounts for business combinations using the acquisition method in accordance with ASC 805. Identifiable assets acquired and liabilities assumed are recognized at their acquisition-date fair values, with any excess of the consideration transferred, the fair value of any previously held equity interest and the fair value of noncontrolling interests over the identifiable net assets acquired recognized as goodwill. In a business combination achieved in stages, any previously held equity interest is remeasured to fair value at the acquisition date, with the resulting gain or loss recognized in earnings.
F-12
| WISeKey International Holding Ltd | Condensed Consolidated Financial Statements as of June 30, 2026 |
Investment in Equity Securities
Equity securities are investments representing an ownership interest in an entity, excluding investments in consolidated subsidiaries, investments accounted for under the equity method and instruments subject to other applicable U.S. GAAP. The Group measures equity securities at fair value through earnings, except for equity securities without readily determinable fair values for which the Group has elected the measurement alternative under ASC 321. Under the measurement alternative, investments are measured at cost, less impairment, adjusted for observable price changes in orderly transactions for identical or similar investments of the same issuer.
Investments in Unconsolidated Affiliates
In line with ASC 323, the Group accounts for investments in entities over which it has significant influence, but not control, using the equity method of accounting. The Group evaluates the need for the equity method where influence exists despite lower ownership levels. Under the equity method, investments are initially recorded at cost and subsequently adjusted for the Group’s proportionate share of the investee’s net income or loss and dividends received. The Group’s share of the income or loss of these companies is reported in the consolidated income statement under equity in earnings of unconsolidated affiliates. The investment in these companies is reported in the consolidated balance sheet under investments in unconsolidated affiliates or related party affiliates.
The Group evaluates equity method investments for impairment when events or changes in circumstances indicate that the fair value of an investment may have declined below its carrying amount. If the decline in value is determined to be other than temporary, the investment is written down to fair value, and the impairment loss is recognized in earnings.
Segment Reporting
The chief operating decision maker, who is also the Chief Executive Officer, regularly reviews information collated into two segments for purposes of allocating resources and assessing budgets and performance. The Group reports its financial performance based on this segment structure described in Note 37.
Variable Interest Entities
The Group evaluates its interests in legal entities under ASC 810 to determine whether it has a controlling financial interest under the voting-interest or variable-interest entity model. A variable interest entity is consolidated when the Group is its primary beneficiary, meaning that the Group has both the power to direct the activities of the variable interest entity that most significantly impact its economic performance and the obligation to absorb losses or the right to receive benefits that could potentially be significant to the variable interest entity. The Group reassesses its consolidation conclusions when changes in governance, funding or other arrangements occur.
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.
F-13
| WISeKey International Holding Ltd | Condensed Consolidated Financial Statements as of June 30, 2026 |
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.
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 principles-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.

| WISeKey International Holding Ltd | Condensed Consolidated Financial Statements as of June 30, 2026 |
In December 2025, the FASB issued ASU 2025-11, Interim Reporting (Topic 270): Narrow Scope Improvements. This update clarifies and refines the guidance in ASC 270 to improve how entities prepare and disclose interim financial statements and notes in accordance with U.S. GAAP.
Summary: The update specifies that ASC 270 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 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 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.
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. The Group’s cash and cash equivalents are mostly held with one large financial institution. Management believes that the financial institution that holds most of its 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. It generally does 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 net trade accounts receivable balances (excluding related party receivables) represented 10% or more of total consolidated net trade accounts receivable balances as of June 30, 2026 and December 31, 2025. In addition, the Group notes that some of its clients are contract manufacturers for the same companies; should these companies reduce their operations or change contract manufacturers, this would cause a decrease in the Group’s customer orders which would adversely affect its operating results.

Note 6. Business Combination
On June 1, 2026 (the “Acquisition Date”), WISeKey, through its subsidiary SEALSQ, 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
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 | ||||
| Fair value of interest acquired through the June 2026 capital increase | ||||
| Total consideration attributable to SEALSQ | ||||
| Fair value of noncontrolling interests (“NCI”) | ||||
| Aggregate acquisition-date fair value, including NCI | ||||
The amounts above are based on the implied Acquisition Date equity value derived from the June 2026 capital increase. The USD
Immediately before the Acquisition Date, the Group remeasured its previously held equity interest in Wecan to its acquisition-date fair value of USD
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.

| WISeKey International Holding Ltd | Condensed Consolidated Financial Statements as of June 30, 2026 |
The following table summarizes the preliminary allocation of the acquisition-date fair value as of June 1, 2026:
| USD’000 | ||||
| Restricted cash | ||||
| Technology | ||||
| Trademarks | ||||

| Accounts payable | ( | ) | ||
| Total liabilities assumed | ( | ) | ||
| Net identifiable assets acquired | ||||
| Goodwill | ||||
| Aggregate acquisition-date fair value, including NCI | ||||
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 will be recognized in the reporting period in which the adjustment amounts are determined, including the related effects on earnings calculated as if the revised provisional amounts had been recognized on the Acquisition Date.
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

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. |

The following methods and assumptions were used to estimate the fair value of the Group’s 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. |
| - | Crypto assets measured at fair value - fair value remeasured as of reporting period, based on quoted prices on crypto exchanges. |
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 equity securities without a readily determinable fair value are accounted for under the measurement alternative in ASC 321 (cost minus impairment), adjusted for observable price changes, if any, and are therefore not fair value measurements; see Note 23 for the related carrying amounts and impairment assessment.
Note 9. Cash and cash equivalents
Cash and cash equivalents consisted of cash held in bank accounts with major financial institutions, USD fiat balances held on the Coinbase platform that are immediately withdrawable and not subject to restrictions, and investments in money market funds. Cash at banks represents deposits that are readily available. Money market funds represent highly liquid investments that are readily convertible into cash.

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 and 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
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 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 Group’s operating leases relate to premises and office equipment. The Group does not sublease. All of its 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, the Group recognized rent expenses associated with its leases as follows:

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
Impairment reviews have been conducted for the goodwill allocated to the reporting unit (“RU”) relating to the acquisition of SEALSQ France SAS (formerly WISeKey Semiconductors SAS) in 2016. Fair value has been primarily determined using the market approach based on the quoted market price of its publicly traded subsidiary, SEALSQ Corp, the main component of which is SEALSQ France SAS. The Company believes that the quoted share price of SEALSQ Corp provides a reliable observable input (Level 1) under ASC 820. Fair value is higher than its carrying value. Based on the analysis performed, the Company concluded that impairment of goodwill existed for the SEALSQ France SAS reporting unit as of June 30, 2026.
In the ASIC segment, 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.

F-26
| WISeKey International Holding Ltd | Condensed Consolidated Financial Statements as of June 30, 2026 |
The Group’s investments in FOSSA do not have readily determinable fair values. The Group has elected the measurement alternative under ASC 321, under which each investment is measured at cost, less impairment, adjusted for observable price changes in orderly transactions for identical or similar investments of the same issuer.
As of June 30, 2026, the Group performed a qualitative impairment assessment and evaluated available transactions involving FOSSA securities for observable price changes. The Group considered the differing economic and governance rights of the securities issued in FOSSA’s financing transactions and concluded that no transaction required an adjustment to the carrying amount of the Group’s existing investments. No impairment loss or adjustment for observable price changes was therefore recorded during the six months ended June 30, 2026.

Note 29. Employee benefit plans
Defined benefit post-retirement plan
The Group maintains defined benefit pension plans covering employees in Switzerland and France. These include plans maintained by WISeKey SA, WISeKey International Holding Ltd., SEALSQ Corp, Wecan and Miraex SA for employees in Switzerland, and plans maintained by SEALSQ France SAS and IC’Alps SAS for employees in France.
All plans are accounted for as defined benefit plans 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.
The Group recorded 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 WISeKey SA, WISeKey International Holding Ltd., 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 SA is based on annual personnel costs and assumptions as of May 31, 2026.

Lease commitments
The future payments due under leases are shown in Note 18.
Guarantees
The Group’s software and hardware product sales agreements generally include certain provisions for indemnifying customers against liabilities if the Group’s products infringe a third party’s intellectual property rights. Certain of its product sales agreements also include provisions indemnifying customers against liabilities in the event the Group breaches confidentiality or service level requirements. It is not possible to determine the maximum potential amount under these indemnification agreements due to the Group’s lack of history of prior indemnification claims and the unique facts and circumstances involved in each particular agreement. To date, the Group has not incurred any costs as a result of such indemnifications and has not accrued any liabilities related to such obligations in its consolidated financial statements.
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.
F-33
| WISeKey International Holding Ltd | Condensed Consolidated Financial Statements as of June 30, 2026 |
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
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. 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 its lack of history of prior indemnification claims and the unique facts and circumstances involved in each particular agreement. To date, the Group did not incur any costs as a result of such indemnifications and have not accrued any liabilities related to such obligations in its consolidated financial statements.

Note 32. 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, and, with the acquisition of IC’Alps, from the delivery of custom ASIC (Application-Specific Integrated Circuit) design and development services during the pre-production phase, and the supply of 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 table shows the 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 |
| Certificates | The Group recognizes revenue on a straight-line basis over the validity period of the certificate, which is usually one to three years. This period starts after the certificate has been issued by the Certificate Authority and may be used by the customer for authentication and signature, by checking the certificate validity against the Root of Trust which is maintained by the Group on its IT infrastructure. Customers pay for certificates when certificates are issued and invoiced. The excess of payments over recognized revenue is shown as deferred revenue. |
| 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 certificate life-cycle-management solutions and signing and authentication solutions, as well as 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 quarterly or yearly service periods; 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, including 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-shelf 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. |
| Space and satellite technology services | The Group provides project-based space and satellite technology services, including technical studies, demonstrators, hardware-related deliverables and associated support services. These services generally represent distinct performance obligations under customer contracts. The Group recognizes revenue at a point in time when the relevant contractual deliverable or service has been performed and accepted by the customer, which generally occurs upon delivery of the technical analysis, report, demonstrator, hardware-related deliverable, or other agreed milestone. Customers typically pay upon invoicing following completion and acceptance of the relevant deliverable or milestone. |
| 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. |

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 a WIHN Class B Share. Expected volatility is based on historical volatility of WIHN Class B Shares.
Prior to 2025, all option grants were classified as equity instruments. However, in the second half of 2025, WISeKey management decided to permit the withholding of shares as a means of meeting the grantee’s tax obligation in relation to their option exercise, which means that, for jurisdictions that do not have any withholding requirement, the awards are accounted for as liabilities under ASC 718, measured at fair value on the grant date and remeasured at each reporting period until settlement. The reclassification of some options from equity to liability and the related remeasurement at fair value at December 31, 2025 generated a net credit to the income statement of USD

Note 37. Segment reporting
The Group has
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.
Both the Semiconductors and ASIC reportable segments are strategic business units that offer specific products 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+ and FIPS 140-3-certified secure microprocessors. The ASIC segment’s operations include a complete offering of Application Specific Integrated Circuit (ASIC) and System on Chip (SoC) development, from circuit specification and mastering design in-house through qualification and management of the entire production supply chain. The ASIC reportable segment did not exist prior to August 4, 2025, when the Group acquired IC’Alps.
The Semiconductors segment is subject to export controls and government procurement regulations. The ASIC segment may also be subject to customer-specific regulatory and qualification requirements depending on end-market applications.
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.
F-45
| WISeKey International Holding Ltd | Condensed Consolidated Financial Statements as of June 30, 2026 |
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 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.

For purposes of the diluted net loss per share calculation, stock options, convertible instruments and warrants are considered potentially dilutive securities and are excluded from the calculation of diluted net loss per share, because their effect would be anti-dilutive. Therefore, the basic and diluted net loss per share were the same for the six months ended June 30, 2026, and June 30, 2025, due to the Group’s net loss position.

Note 42. Impacts of ongoing conflicts
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 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 material and other input costs, which may impact the Group’s supply chain in the future.
As of June 30, 2026, the Group 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. The Group will continue to monitor these areas of increased risk for material changes.

Impacts of the Israel–Hamas conflict 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 has threatened some commercial routes, especially traffic through the Strait of Hormuz.
The 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. The Group’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, the Group 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. The Group will continue to monitor these areas of increased risk for material changes.
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 the Group supplies 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, the Group 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. WISeKey will continue to monitor these areas of increased risk for material changes.
