STRATEGIC REPORT
FOR THE YEAR ENDED 31 DECEMBER 2024

Introduction
 
The directors present their Strategic Report for the Company for the year ended 31 December 2024.

Business review
 
The business volume decreased in 2024 due to several projects completing their regular roll-out of our next-generation disaggregated fibre access platforms. The customer base has continued to grow, as Alt Net service providers have selected Adtran platforms and accelerated their network builds.

Principal risks and uncertainties
 
The dominant risks are supply chain constraints limiting our ability to serve customers in a timely manner and also the related price increases for electronic components and service costs, e.g. freight that have resulted from the imbalance of demand and supply. Furthermore, a scarcity of skilled personnel might have a negative impact on the roll-out performance. 

Financial key performance indicators
 
As a NASDAQ listed company, ADTRAN, Inc. does not publish KPIs on a country level. During quarterly calls with investors, guidance is provided for the respective upcoming quarter. See the most recent 10-K and 10-Q at investors.adtran.com.

Directors' statement of compliance with duty to promote the success of the Company
 
The Directors, as part of the Office of the Executive Chairman (“the OEC”), in line with their duties under section 172 of the Companies Act 2006 (“s.172”), act in a way that they consider would be most likely to promote the success of the Company for the benefit of its members as a whole, and in doing so have regard to a range of matters when making decisions for the long term, including the list of non exhaustive matters as set out in s.172. Factors contained within s.172 are considered when making key decisions and considering matters that are of strategic importance to the Company.
As part of the OEC’s decision-making process, consideration is given to the potential impact of decisions on relevant stakeholders, which include employees, customers, suppliers and regulators, whilst also having regard to a number of broader factors, including the impact of the Company’s operations on the community and environment, responsible business practices and the likely consequences of decisions in the long term.
The OEC regularly reviews the Company’s principal stakeholders and how it engages with them. This is achieved including through information provided by management and also by direct engagement by all of the OEC members with stakeholders themselves.
Further information on how the Company engages with its principal stakeholders can be found in the Directors' Report.


This report was approved by the board on 4 June 2026 and signed on its behalf.

INDEPENDENT AUDITORS' REPORT TO THE MEMBERS OF ADTRAN EUROPE LIMITED
 

Opinion


We have audited the financial statements of Adtran Europe Limited (the 'Company') for the year ended 31 December 2024, which comprise the Statement of Comprehensive Income, the Balance Sheet, the Statement of Changes in Equity and the related notes, including a summary of significant accounting policiesThe financial reporting framework that has been applied in their preparation is applicable law and United Kingdom Accounting Standards, including Financial Reporting Standard 102 ‘The Financial Reporting Standard applicable in the UK and Republic of Ireland' (United Kingdom Generally Accepted Accounting Practice).


In our opinion the financial statements:


give a true and fair view of the state of the Company's affairs as at 31 December 2024 and of its profit for the year then ended;
have been properly prepared in accordance with United Kingdom Generally Accepted Accounting Practice; and
have been prepared in accordance with the requirements of the Companies Act 2006.


Basis for opinion


We conducted our audit in accordance with International Standards on Auditing (UK) (ISAs (UK)) and applicable law. Our responsibilities under those standards are further described in the Auditors' responsibilities for the audit of the financial statements section of our report. We are independent of the Company in accordance with the ethical requirements that are relevant to our audit of the financial statements in the United Kingdom, including the Financial Reporting Council's Ethical Standard and we have fulfilled our other ethical responsibilities in accordance with these requirements. We believe that the audit evidence we have obtained is sufficient and appropriate to provide a basis for our opinion.


Conclusions relating to going concern


In auditing the financial statements, we have concluded that the directors' use of the going concern basis of accounting in the preparation of the financial statements is appropriate.


Based on the work we have performed, we have not identified any material uncertainties relating to events or conditions that, individually or collectively, may cast significant doubt on the Company's ability to continue as a going concern for a period of at least twelve months from when the financial statements are authorised for issue.


Our responsibilities and the responsibilities of the directors with respect to going concern are described in the relevant sections of this report.

Other information


The other information comprises the information included in the Annual Report other than the financial statements and our Auditors' Report thereon. The directors are responsible for the other information contained within the Annual ReportOur opinion on the financial statements does not cover the other information and, except to the extent otherwise explicitly stated in our report, we do not express any form of assurance conclusion thereon. Our responsibility is to read the other information and, in doing so, consider whether the other information is materially inconsistent with the financial statements or our knowledge obtained in the course of the audit, or otherwise appears to be materially misstated. If we identify such material inconsistencies or apparent material misstatements, we are required to determine whether this gives rise to a material misstatement in the financial statements themselves. If, based on the work we have performed, we conclude that there is a material misstatement of this other information, we are required to report that fact.


We have nothing to report in this regard.


Opinion on other matters prescribed by the Companies Act 2006
 

In our opinion, based on the work undertaken in the course of the audit:


the information given in the Strategic Report and the Directors' Report for the financial year for which the financial statements are prepared is consistent with the financial statements; and
the Strategic Report and the Directors' Report have been prepared in accordance with applicable legal requirements.


Matters on which we are required to report by exception
 

In the light of the knowledge and understanding of the Company and its environment obtained in the course of the audit, we have not identified material misstatements in the Strategic Report or the Directors' Report.


We have nothing to report in respect of the following matters in relation to which the Companies Act 2006 requires us to report to you if, in our opinion:


adequate accounting records have not been kept, or returns adequate for our audit have not been received from branches not visited by us; or
the financial statements are not in agreement with the accounting records and returns; or
certain disclosures of directors' remuneration specified by law are not made; or
we have not received all the information and explanations we require for our audit.


Responsibilities of directors
 

As explained more fully in the Directors' Responsibilities Statement set out on page 3, the directors are responsible for the preparation of the financial statements and for being satisfied that they give a true and fair view, and for such internal control as the directors determine is necessary to enable the preparation of financial statements that are free from material misstatement, whether due to fraud or error.


In preparing the financial statements, the directors are responsible for assessing the Company's ability to continue as a going concern, disclosing, as applicable, matters related to going concern and using the going concern basis of accounting unless the directors either intend to liquidate the Company or to cease operations, or have no realistic alternative but to do so.

INDEPENDENT AUDITORS' REPORT TO THE MEMBERS OF ADTRAN EUROPE LIMITED (CONTINUED)


Auditors' responsibilities for the audit of the financial statements
 

Our objectives are to obtain reasonable assurance about whether the financial statements as a whole are free from material misstatement, whether due to fraud or error, and to issue an Auditors' Report that includes our opinion. Reasonable assurance is a high level of assurance, but is not a guarantee that an audit conducted in accordance with ISAs (UK) will always detect a material misstatement when it exists. Misstatements can arise from fraud or error and are considered material if, individually or in the aggregate, they could reasonably be expected to influence the economic decisions of users taken on the basis of these financial statements.


Irregularities, including fraud, are instances of non-compliance with laws and regulations. We design procedures in line with our responsibilities, outlined above, to detect material misstatements in respect of irregularities, including fraud. The extent to which our procedures are capable of detecting irregularities, including fraud is detailed below:

We determined that the laws and regulations which are directly relevant to the financial statements are those that relate to the reporting framework Financial Reporting Standard 102 and the relevant tax compliance regulations in the jurisdictions in which the Company operates. We evaluated the extent of compliance with these laws and regulations as part of our procedures on the related financial statement items.
In addition, there are other significant laws and regulations which may have an effect on the determination of the amounts and disclosures in the financial statements being those laws and regulations employment law, data protection regulation, fraud, bribery and corruption. For these laws and regulations, the consequences of non-compliance could have a material effect on amounts or disclosures in the financial statements, for instance through fines or litigation being imposed. As required by the auditing standards, auditing procedures in respect of non-compliance with these identified laws and regulations are limited to enquiry of the Directors and other management and inspection of regulatory and legal correspondence, if any.
We assessed the susceptibility of the Company’s financial statements to material misstatement, including how fraud might occur, by meeting with a number of individuals, including with individuals outside of the finance function, and conducted interviews to understand where they considered there was susceptibility to fraud. We evaluated management’s incentives and opportunities for fraudulent manipulation of the financial statements (including the risk of override of controls) and determined that the principal risks were related to areas of estimate and judgement in the financial statements.
Based on this understanding we designed our audit procedures to identify non-compliance with such laws and regulations and fraud risks identified in the paragraphs above. In addition to the audit procedures, we remained alert to any indications of non-compliance throughout the audit. The specific audit procedures performed included:
°Reviewed large and unusual bank transactions;
°Challenging assumptions and judgements made by management in its significant accounting estimates;
°Identifying and testing journal entries.

Because of the inherent limitations of an audit, there is a risk that we will not detect all irregularities, including those leading to a material misstatement in the financial statements or non-compliance with regulation. This risk increases the more that compliance with a law or regulation is removed from the events and transactions reflected in the financial statements, as we will be less likely to become aware of instances of non-compliance. The risk is also greater regarding irregularities occurring due to fraud rather than error, as fraud involves intentional concealment, forgery, collusion, omission or misrepresentation.
A further description of our responsibilities for the audit of the financial statements is located on the Financial Reporting Council's website at: www.frc.org.uk/auditorsresponsibilities. This description forms part of our Auditors' Report.

2.Accounting policies (continued)

 
2.4

Foreign currency translation

Functional and presentation currency

The Company's functional and presentational currency is GBP.

Transactions and balances

Foreign currency transactions are translated into the functional currency using the spot exchange rates at the dates of the transactions.

At each period end foreign currency monetary items are translated using the closing rate. Non-monetary items measured at historical cost are translated using the exchange rate at the date of the transaction and non-monetary items measured at fair value are measured using the exchange rate when fair value was determined.

Foreign exchange gains and losses resulting from the settlement of transactions and from the translation at period-end exchange rates of monetary assets and liabilities denominated in foreign currencies are recognised in profit or loss except when deferred in other comprehensive income as qualifying cash flow hedges.

Foreign exchange gains and losses that relate to borrowings and cash and cash equivalents are presented in the Statement of Comprehensive Income within 'finance income or costs'. All other foreign exchange gains and losses are presented in profit or loss within 'other operating income'.

2.5

Revenue

The revenue received in respect of delivery of goods and services provided per the terms of the contract was recognised within revenue as outlined in further detail below. Any associated costs in respect of delivering these goods and services were recognised in Cost of Sales. Where the UK company has directly entered into the contract, the company is deemed to be acting as principal even if the parent has provided a written guarantee to the UK customer.
The Company processes a transfer pricing adjustment which ensures that an operating profit margin of 3% is achieved by the company. In the current year, Adtran Inc has raised an invoice to the Company and this is recorded within cost of sales.
Revenue is recognised to the extent that it is probable that the economic benefits will flow to the Company and the revenue can be reliably measured. Revenue is measured as the fair value of the consideration received or receivable, excluding discounts, rebates, value added tax and other sales taxes. The following criteria must also be met before revenue is recognised:

Sale of goods

Revenue from the sale of goods is recognised when all of the following conditions are satisfied:
the Company has transferred the significant risks and rewards of ownership to the buyer;
the Company retains neither continuing managerial involvement to the degree usually associated with ownership nor effective control over the goods sold;
the amount of revenue can be measured reliably;
it is probable that the Company will receive the consideration due under the transaction; and
the costs incurred or to be incurred in respect of the transaction can be measured reliably.

Rendering of services

Revenue from a contract to provide services is recognised in the period in which the services are provided in accordance with the stage of completion of the contract when all of the following conditions are satisfied:
the amount of revenue can be measured reliably;
it is probable that the Company will receive the consideration due under the contract;
the stage of completion of the contract at the end of the reporting period can be measured reliably; and
the costs incurred and the costs to complete the contract can be measured reliably.

 
2.6

Operating leases: the Company as lessee

Rentals paid under operating leases are charged to profit or loss on a straight-line basis over the lease term.

Benefits received and receivable as an incentive to sign an operating lease are recognised on a straight-line basis over the lease term, unless another systematic basis is representative of the time pattern of the lessee's benefit from the use of the leased asset.

NOTES TO THE FINANCIAL STATEMENTS
FOR THE YEAR ENDED 31 DECEMBER 2024

2.Accounting policies (continued)

 
2.7

Pensions

Defined contribution pension plan

The Company operates a defined contribution plan for its employees. A defined contribution plan is a pension plan under which the Company pays fixed contributions into a separate entity. Once the contributions have been paid the Company has no further payment obligations.

The contributions are recognised as an expense in profit or loss when they fall due. Amounts not paid are shown in accruals as a liability in the Balance Sheet. The assets of the plan are held separately from the Company in independently administered funds.

 
2.8

Interest income

Interest income is recognised in profit or loss using the effective interest method.

 
2.9

Share-based payments

Where share options are awarded to employees, the fair value of the options at the date of grant is charged to profit or loss over the vesting period. Non-market vesting conditions are taken into account by adjusting the number of equity instruments expected to vest at each balance sheet date so that, ultimately, the cumulative amount recognised over the vesting period is based on the number of options that eventually vest. Market vesting conditions are factored into the fair value of the options granted. The cumulative expense is not adjusted for failure to achieve a market vesting condition.
The fair value of the award also takes into account non-vesting conditions. These are either factors beyond the control of either party (such as a target based on an index) or factors which are within the control of one or other of the parties (such as the Company keeping the scheme open or the employee maintaining any contributions required by the scheme).
Where the terms and conditions of options are modified before they vest, the increase in the fair value of the options, measured immediately before and after the modification, is also charged to profit or loss over the remaining vesting period.
Where equity instruments are granted to persons other than employees, profit or loss is charged with fair value of goods and services received.

NOTES TO THE FINANCIAL STATEMENTS
FOR THE YEAR ENDED 31 DECEMBER 2024

2.Accounting policies (continued)

 
2.10

Current and deferred taxation

The tax expense for the year comprises current and deferred tax. Tax is recognised in profit or loss except that a charge attributable to an item of income and expense recognised as other comprehensive income or to an item recognised directly in equity is also recognised in other comprehensive income or directly in equity respectively.

The current income tax charge is calculated on the basis of tax rates and laws that have been enacted or substantively enacted by the balance sheet date in the countries where the Company operates and generates income.

Deferred tax balances are recognised in respect of all timing differences that have originated but not reversed by the balance sheet date, except that:
The recognition of deferred tax assets is limited to the extent that it is probable that they will be recovered against the reversal of deferred tax liabilities or other future taxable profits; and
Any deferred tax balances are reversed if and when all conditions for retaining associated tax allowances have been met.

Deferred tax balances are not recognised in respect of permanent differences except in respect of business combinations, when deferred tax is recognised on the differences between the fair values of assets acquired and the future tax deductions available for them and the differences between the fair values of liabilities acquired and the amount that will be assessed for tax. Deferred tax is determined using tax rates and laws that have been enacted or substantively enacted by the balance sheet date.


 
2.11

Tangible fixed assets

Tangible fixed assets under the cost model are stated at historical cost less accumulated depreciation and any accumulated impairment losses. Historical cost includes expenditure that is directly attributable to bringing the asset to the location and condition necessary for it to be capable of operating in the manner intended by management.

Depreciation is charged so as to allocate the cost of assets less their residual value over their estimated useful lives, using either the straight-line or reducing balance method.

Depreciation is provided on the following basis:

Long-term leasehold property
-
Over 5 years on a straight line basis
Plant and machinery
-
Over 4 years on a straight line basis
Fixtures and fittings
-
25% reducing basis
Computer equipment
-
35% reducing basis

The assets' residual values, useful lives and depreciation methods are reviewed, and adjusted prospectively if appropriate, or if there is an indication of a significant change since the last reporting date.

Gains and losses on disposals are determined by comparing the proceeds with the carrying amount and are recognised in profit or loss.

2.12

Stocks

Stocks are stated at the lower of cost and net realisable value, being the estimated selling price less costs to complete and sell. Cost is based on the cost of purchase on a first in, first out basis. Work in progress and finished goods include labour and attributable overheads.

The company holds stock to ensure it is able to fulfil UK orders which are supplied as per the terms of the contracts in place with UK customers. The intercompany agreement in place with the US parent company, Adtran Inc, confirms that Adtran Inc warrants that the products in stock should be of satisfactory quality and as a result there is no stock provision recognised as faulty or obsolete stock items would be returned to Adtran Inc.

  
2.13

Financial instruments

The Company only enters into basic financial instrument transactions that result in the recognition of financial assets and liabilities like trade and other debtors and creditors, loans from banks and other third parties, loans to related parties and investments in ordinary shares. 

Debt instruments (other than those wholly repayable or receivable within one year), including loans and other accounts receivable and payable, are initially measured at present value of the future cash flows and subsequently at amortised cost using the effective interest method. Debt instruments that are payable or receivable within one year, typically trade debtors and creditors, are measured, initially and subsequently, at the undiscounted amount of the cash or other consideration expected to be paid or received. However, if the arrangements of a short-term instrument constitute a financing transaction, like the payment of a trade debt deferred beyond normal business terms or in case of an out-right short-term loan that is not at market rate, the financial asset or liability is measured, initially at the present value of future cash flows discounted at a market rate of interest for a similar debt instrument and subsequently at amortised cost, unless it qualifies as a loan from a director in the case of a small company, or a public benefit entity concessionary loan.
Financial assets that are measured at cost and amortised cost are assessed at the end of each reporting period for objective evidence of impairment. If objective evidence of impairment is found, an impairment loss is recognised in the Statement of comprehensive income.

Judgements in applying accounting policies and key sources of estimation uncertainty

Agent vs Principal
Where the Company enters into contracts with UK customers and is delivering those contracts in the UK, the Company is deemed to be acting as principal. There are indicators that contradict this as there is an intercompany agreement which stipulates that the fulfilment of orders ultimately lie with Adtran Inc, the ultimate parent company, and some of the UK contracts do also refer to the Adtran Inc as a guarantor. That said, the Company enters into the contracts with the UK customers and the Company has the primary responsibility of delivering the goods and services as specified by the customer. 
Furthermore, there are indicators within the intercompany agreement which suggest that the risks associated with holding stock are with the US parent company, however, given that the stock is vital to delivery of the products and services associated with the contracts in place with UK customers and given the Company is responsible for storing the stock in the UK, this stock is held on the Company's balance sheet. There is no stock provision, as stock can be returned to the US parent company, Adtran Inc, if it is faulty or obsolete. Additionally, there is no warranty provision recognised in the accounts, as Adtran Inc are liable to pay any potential warranty costs incurred. 
Tangible fixed assets
Fixed assets are depreciated over their useful lives taking into account residual values, where appropriate. The actual lives of the assets are assessed annually and may vary depending on a number of factors. In re-assessing asset lives, factors such as technological innovation are taken into account. Residual value assessments consider issues such as future market conditions, the remaining life of the assets and projected disposal values.
Maintenance revenue
The maintenance service periods range from one month to five years. Customers are typically invoiced and pay for maintenance services at the beginning of the maintenance period. Revenue for maintenance services is recognised on a straight-line basis, over the maintenance period, as customers benefit evenly throughout the contract term. As such, the Company recognises deferred revenue for the maintenance services. The total balance of deferred income as at 31 December 2024 was £7.3m (2023  - £9.1m).
Debtor recoverability
Management applies its judgement when estimating the recoverable value of trade debtors, intercompany debtors, and other debtors. When assessing the recoverability, management considers factors including but not limited to the aging profile of the debtors and historical experience as well as certain strategic factors.
As at the date of signing the accounts, an amount of £490k has not yet been recovered in respect of trade debtors outstanding as at the year end. Although the timing of the collection of the amount is uncertain, management believe this amount will be recoverable.

The Company is a subsidiary of Adtran Inc. and forms part of a multinational group that is expected to be within the scope of the Pillar Two rules. The ultimate responsibility for assessing and managing the Group’s exposure to Pillar Two income taxes, including the preparation and filing of any GloBE Information Return, rests with another group entity and central tax function.
For the year ended 31 December 2024, no material Pillar Two current tax expense has been recognised in these financial statements. The Group continues to assess the potential exposure to top-up taxes in various jurisdictions, however, based on information available at the reporting date, there is not expected to be any exposure.
The Company will continue to monitor developments in legislation and the Group’s effective tax rate profile across jurisdictions, and will recognise any Pillar Two tax liabilities as and when they arise.
