Results of operations, net assets and financial position

Business development and operational performance

Revenue development and revenues by region

Revenues represent one of the four key performance indicators for Adtran Networks. The group's revenues in 6M 2024 amounted to EUR 217.8 million and were EUR 131.8 million or (37.7) \% and thus clearly below revenues of EUR 349.5 million in 6M 2023. Compared to revenues of EUR 109.6 million in Q1 2024, revenues in Q2 2024 slightly decreased by $1.3 \%$ to EUR 108.2 million. The decrease in revenues compared to 6M 2023 is driven largely by decreased demand from large network operators and the completion of some significant customer projects in previous periods.

In 6M 2024, EMEA (Europe, the Middle East and Africa) was once again the largest contributing sales region, followed by Americas and Asia-Pacific.

However, year-on-year sales in EMEA decreased significantly to EUR 111.1 million in 6M 2024 compared to EUR 203.3 million in 6M 2023 and represented $51.0 \%$ of total revenues in 6M 2024 after $58.2 \%$ in the prior-year period. In this region the decline compared to the prior year period is due in particular to project related activity coming to a close and reduction in demand from Tier 1large network operators.

Due to the reduced demand from large network operators revenues in Americas also decreased clearly by $33.7 \%$ from EUR 119.6 million in 6M 2023 to EUR 79.2 million in 6M 2024.

In Asia-Pacific, revenue slightly increased by 3.0\% from EUR 26.6 million in 6M 2023 to EUR 27.4 million in 6M 2024. Demand was primarily driven by network operators and enterprise customers.

Cost of goods sold decreased by EUR 90.9 million to EUR 141.0 million in 6M 2024. In 6M 2024, cost of goods sold included EUR 18.3 million (6M 2023: EUR 19.3 million) of amortization of capitalized development projects.
Gross profit reduced from EUR 117.6 million in 6M 2023 to EUR 76.7 million in 6M 2024, with gross margin at $35.2 \%$ in 6M 2024 also above the $33.6 \%$ reported in 6M 2023. The increase in the gross margin in 6M 2024 compared to 6M 2023 in particular results from disproportional reduction in the cost of goods sales in relation to the decline in revenues.

Within operating costs, sales and marketing expenses in 6M 2024 of EUR 30.5 million were below the prior-year number of EUR 35.4 million in 6M 2023. They amounted to $14.0 \%$ of revenues in 6M 2024 after $10.1 \%$ in 6M 2023.

General and administrative expenses of EUR 15.1 million in 6M 2024 also decreased compared to EUR 18.8 million in 6M 2023 and amounted to $6.9 \%$ and $5.4 \%$ of revenues, respectively.

Total R\&D expenses
Net R\&D expenses

At EUR 53.8 million in 6M 2024, R\&D expenses were slightly below the EUR 55.0 million seen in 6M 2023, comprising $24.7 \%$ and $15.7 \%$ of revenues, respectively. Gross R\&D expenses decreased to EUR 74.2 million in 6M 2024 compared to EUR 76.5 million reported in 6M 2023, while income from capitalization of development expenses decreased from EUR 21.5 million in 6M

2023 to EUR 20.4 million in 6M 2024. The capitalization rate in 6M 2024 amounted to $27.6 \%$, down from $28.1 \%$ reported in 6M 2023.

Adtran Networks operating result significantly degraded from positive EUR 14.3 million in 6M 2023 to negative EUR 14.2 million in 6M 2024. In the current period revenues decreased clearly negatively impacting operating result.

Pro forma EBIT represents one of the four key performance indicators for Adtran Networks. As pro forma EBIT excludes noncash charges related to stock compensation and business combinations as well as non-recurring expenses related to M\&A transactions, integration and restructuring measures. The management board of Adtran Networks believes that pro forma EBIT is a more appropriate measure than operating income when benchmarking the group's operational performance against other telecommunications equipment providers. In 6M 2024, Adtran Networks reported a pro forma EBIT of negative EUR 5.9 million after a pro forma EBIT of positive EUR 21.8 million in 6M 2023, representing negative $2.7 \%$ after positive $6.2 \%$ of revenues, respectively.

The reconciliation of operating income (loss) to pro forma EBIT is as follows:

(in millions of EUR) 6M 2024 6M 2023
Operating income (loss) $(14.2)$ 14.3
Expenses related to share-based compensation 2.8 2.4
Amortization of intangible assets from business combinations 0.7 1.8
Expenses related to M\&A transactions, integration and restructuring measures 4.8 3.4
Pro forma EBIT $(5.9)$ 21.8

Beyond the operating result net income in 6M 2024 is impacted by net interest expenses of EUR 1.8 million (6M 2023: net interest expenses of EUR 1.7 million), which includes interest effects from lease accounting of EUR 0.7 million (6M 2023: EUR 0.3 million). Furthermore, net financial losses of EUR 0.1 million (6M 2023: net financial losses of EUR 2.8 million) relating to the revaluation of foreign currency assets and liabilities and the result on hedging instruments, impacted the net income in 6M 2024.

In 6M 2024, the group reported an income tax income of EUR 14.0 million after an income tax expense of EUR 2.9 million in 6M 2023. In both periods income tax effects result from the application of the expected tax rate to the relevant income before tax of the respective entity of the Adtran Networks group.

Summary: Business development and operational performance

In 6M 2024, Adtran Networks SE recorded a significant decrease in revenues with gross margin improving at the same time compared to the previous year. Operating result degraded significantly due to a disproportionately low decline in costs in relation to the decrease in revenues and was only partially offset by tax income. Thus, Adtran Networks reports a substantial decline in net result from a net profit of EUR 6.9 million in 6M 2023 to a net loss of EUR 2.0 million in the current period.

Net assets and financial position

Balance sheet structure

Adtran Networks total assets increased by EUR 24.9 million from EUR 657.8 million at the end of 2023 to EUR 682.7 million at the end of June 2024.
img-2.jpeg

Current assets amounted to EUR 346.1 million at the end of 6M 2024, EUR 11.8 million lower than the corresponding balance of EUR 357.9 million at the end of 2023 and accounted for $50.7 \%$ and $54.4 \%$ of total assets at these reporting dates, respectively. The decrease in current assets was mainly due to decreased inventories from EUR 106.3 million on December 31, 2023 to EUR 90.3 million at the end of 6M 2024. In 6M 2024 inventory turns declined to $2,9 \mathrm{x}$ compared to the value of $3,3 \mathrm{x}$ in 12 M 2023. Trade receivables decreased from EUR 115.6 million on December 31, 2023 to EUR 99.5 million at the end of 6M 2024 due to declined revenues in the current period when comparing to previous quarters. $\mathrm{DSO}^{7}$ were at 88 days in 6M 2024 and 71 days in 12M 2023. In contrast, cash and cash equivalents increased to EUR 41.5 million after EUR 30.6 million reported at the end of 2023. This results in particular from the cash inflows from financing activities and positive development of operating cash flow as further explained in the cash flow section.

Non-current assets increased clearly to EUR 336.6 million at the end of 6M 2024 from EUR 299.9 million at year-end 2023. The increase is due in particular to the rise in deferred tax assets due to the recognition of deferred tax assets on loss carryforwards from EUR 11.7 million at the end of 2023 to EUR 28.2 million as at June 30, 2024. In addition, the change in non-current assets was influenced in particular by the issue of a bond to Adtran, Inc. described in the Investments section.

Meaningful additional assets belonging to Adtran Networks are the broad and global customer base of several hundred service providers and thousands of enterprises, the "ADVA", "Oscilloquartz" and "Ensemble" brands, the vendor and partner relationships and a highly motivated and skilled global team. These assets are not recognized in the balance sheet. Customer satisfaction as measured by the net promoter score represents one of the group's four key performance indicators. Further information on the development of the Net Promoter Score ${ }^{8}$ is presented in the Annual Report 2023.

On the equity and liabilities side, current liabilities slightly increased by EUR 2.3 million from EUR 145.5 million on December 31, 2023 to EUR 147.8 million on June 30, 2024. Other current liabilities increased by EUR 4.7 million to EUR 41.8 million as of June 30, 2024. Current contract liabilities amounted to EUR 31.2 million as of June 30, 2024, compared to EUR 25.3 million reported at year-end 2023. At the same time, trade payables decreased to EUR 34.4 million at the end of 6M 2024, thus being EUR 8.7 million below the EUR 43.1 million reported at the end of December 2023. In 6M 2024, DPO ${ }^{9}$ amounted to 76 days compared to 62 days in 12M 2023.

The percentage of detractors is then subtracted from the percentage of promoters to obtain a net promoter score.

Non-current liabilities of EUR 154.8 million at the end of 6M 2024 increased from the EUR 134.3 million reported at the end of 2023. This significant increase is due in particular to the refinancing via a bank loan of EUR 70.1 million (USD 75.0 million) at the end of 6M 2024. The loan of EUR 52.8 million granted by the Adtran Holdings, Inc. at the end of 2023 was repaid in full in this context.

Stockholders' equity increased from EUR 378.0 million reported on December 31, 2023, to EUR 380.1 million on June 30, 2024. The equity ratio was at $55.7 \%$ on June 30, 2024, after $57.5 \%$ on December 31, 2023, while the non-current assets ratio amounted to $112.9 \%$ and $126.0 \%$, respectively, with stockholders' equity fully covering the non-current assets.

Capital expenditures

Capital expenditures for additions to property, plant and equipment in 6M 2024 amounted to EUR 5.6 million, down from the EUR 9.0 million seen in 6M 2023. The previous year's figure included investments in the expansion of the Terafactory in Meiningen.

Capital expenditures for intangible assets of EUR 25.4 million in 6M 2024 increased from EUR 22.8 million in 6M 2023. This total consists of capitalized development projects of EUR 20.5 million in 6M 2024 after EUR 21.5 million in 6M 2023 and capital expenditures for other intangible assets of EUR 5.0 million in 6M 2024 after EUR 1.3 million in 6M 2023. The investments in other intangible assets in the prior year period included in particular the capitalization of a joint development.

On June 4, 2024, Adtran Networks SE issued a loan to Adtran, Inc. After taking into account the interest accrued up to the end of the quarter and deducting the pro rata upfront fees, arrangement fees and legal fees charged on by Adtran, Inc. that were incurred as part of a joint credit agreement with Wells Fargo, the carrying amount of the loan on June 30, 2024 was EUR 15.5 million. Further information on the loan can be found in note (13) in the notes section of this report.

Cash flow

(in millions of EUR) 6M 2024 Portion of cash 6M 2023 Portion of cash
Operating cash flow 35.8 $86.3 \%$ 21.3 $43.8 \%$
Investing cash flow (39.4) $(95.1) \%$ (31.7) $(65.2) \%$
Financing cash flow 14.6 $35.2 \%$ 1.7 $3.5 \%$
Net effect of foreign currency translation on cash and cash equivalents - $(0.1) \%$ (1.1) $(2.4) \%$
Net change in cash and cash equivalents 10.9 $26.3 \%$ (9.8) $(20.3) \%$
Cash and cash equivalents at the beginning of the period 30.6 $73.7 \%$ 58.4 $120.3 \%$
Cash and cash equivalents at the end of the period 41.5 $100.0 \%$ 48.6 $100.0 \%$

Cash flow from operating activities was positive EUR 35.8 million in 6M 2024, after positive EUR 21.3 million in 6M 2023. The significant improvement in 6M 2024 is in particular due to high cash inflows from net working capital compared with the corresponding prior-year period.

Cash flow from investing activities amounted to negative EUR 39.4 million in 6M 2024 after negative EUR 31.7 million in 6M 2023. The increased use of funds for investing activities is largely due to the grant of a loan to Adtran, Inc. as described in the capital expenditure section above..

Finally, net cash inflows of EUR 14.6 million were reported from financing activities in 6M 2024, after cash inflows of EUR 1.7 million from financing activities in 6M 2023. In 6M 2024, the cash inflow results in particular from from taking out a new loan. The funds received from this loan were partially used to fully repay the loan to Adtran Holdings, Inc.

Overall, including the net effect of foreign currency translation of close to nil, cash and cash equivalents increased by EUR 10.9 million, from EUR 30.6 million at the end of December 2023 to EUR 41.5 million on June 30, 2024. In 6M 2023, cash and cash equivalents had decreased by EUR 9.8 million.

With the exception of local currency regulations for cash and cash equivalents in China amounting to EUR 3.4 million, there were no significant restrictions at the end of the quarter.

Financing and liquidity

Adtran Networks financial management is performed centrally by Adtran Networks SE. Its objective is to provide sufficient funds to ensure ongoing operations and to support the group's projected growth. Beyond the strong equity base appropriate for the business, Adtran Networks finances its business by means of liabilities with maturities typically exceeding the useful life of the assets being financed. For any liability taken, Adtran Networks is focused on minimizing related interest cost, as long as access to funds is not at risk. Excess funds are generally used to redeem liabilities.

Total financial debt increased by EUR 17.3 million to EUR 114.1 million at the end of 6M 2024. Liabilities to banks increased significantly from EUR 13.3 million to EUR 86.3 million. As from Q2 2024, Adtran Networks group has been financed by a joint loan agreement (Senior Secured Credit Facility) together with Adtran Holdings, Inc. at Wells Fargo Bank. On June 30, 2024, this resulted in a financial liability of EUR 70.1 thousand. As described in the cash flow section, the funds received from this loan were used to fully repay the loan provided by Adtran Holdings, Inc. Further information on financial liabilities can be found in note (15) to the consolidated financial statements. The current portion of liabilities from leasing increased by EUR 0.1 million to EUR 5.6 million while the non-current liabilities from leasing decreased by EUR 3.0 million to EUR 22.2 million.

On June 30, 2024, the group had utilized a committed borrowing facilities of USD 100.0 million in the amount of USD 75.0 million (on December 31, 2023: no committed borrowing facilities).

Net cash represents one of the four key performance indicators for Adtran Networks. Mainly due to the previously described decrease in cash and cash equivalents and increased financial liabilities, net debt improved from EUR 42.4 million at the end of 2023 to EUR 33.2 million in 6M 2024. Cash and cash equivalents on June 30, 2024, and on December 31, 2023 were invested mainly in EUR, USD and GBP.

At the end of June 2024 return on capital employed for the rolling twelve months period was at negative $3.1 \%$, down from the positive $3.0 \%$ reported in 12M 2023. This development is mainly due to the declining operating result in 6M 2024.

Summary: Net assets and financial position

At the end of 6M 2024 cash and cash equivalents increased, which contributed to a decrease in net debt. Adtran Networks net assets and financial position remain strong. The equity ratio further slightly decreased to $55.7 \%$ on June 30, 2024 compared to $57.5 \%$ at the end of 2023.

Events after the balance sheet date

There were no events after the balance sheet date that materially impacted the net assets and financial position of the group and Adtran Networks SE on June 30, 2024, or the group's and the company's financial performance for 6M 2024. Also, there were no events considered material for disclosure.

Risk and opportunity report

Adtran Networks future development is subject to various general and group-specific risks, which in certain cases can also endanger the group's continued existence.

The risks and uncertainties as reported in the "risk and opportunity report" section of the Group Management Report 2023 remain unchanged.

Outlook

For Q2 2024 Adtran Networks was able to reported results which were within the expectations despite the continuing difficult market environment. Revenue for Q2 2024 decreased by $36.4 \%$ to EUR 108.2 million compared to EUR 170.2 million in Q2 2023. 6M 2024 revenues were EUR 217.8 million down by $37.7 \%$ compared to EUR 349.5 million in the 6M 2023 period. The pro forma EBIT margin in Q2 2024 decreased to negative $2.3 \%$ compared to positive $7.1 \%$ in Q2 2023. Cash increased from EUR 32.9 million in Q1 2024 to EUR 41.5 million in Q2 2024. The increase is mainly due to a new loan agreement.

The management board expects demand to remain weak in the second half of 2024, especially for optical transmission technology. Global supply chains are largely intact again and Adtran Networks' ability to deliver has normalized due to increasingly local value creation. As a result, many customers no longer see the need to place their orders early. Instead, they are continuing to optimize their inventories and are exercising restraint with regard to debt-financed investments due to the still relatively restrictive interest rate policy of the central banks. This is having a negative impact on incoming orders.

Management expects this trend to continue in the third quarter and to improve again in the fourth quarter at the earliest. Nevertheless, the longer-term macroeconomic environment remains positive for Adtran Networks. The expansion of the communications network infrastructure continues unabated, albeit temporarily slowing down in some areas. The expansion of data centers, the growing importance of artificial intelligence, global initiatives to promote broadband expansion and the digital transformation of the private sector and public authorities and increased security awareness require significant investment in network expansion and digital infrastructure.

With the strategic decisions made in recent years, Adtran Networks has made comprehensive technological preparations for this transformation of networks with the aspects of cloud, mobility, 5G, automation and security. In addition to the high-quality performance features of optical data transmission, precise network synchronization technology and programmable cloud access solutions, the service portfolio is also delivering increasing added value. In addition, new opportunities to gain market share are emerging, particularly in Europe. The now openly communicated skepticism towards Chinese network equipment suppliers, in particular Huawei, and the planned takeover of Infinera by Nokia are reducing the number of potent network equipment suppliers for creating a future based on fiber optics.

(4) Significant accounting judgements, estimates and assumptions

The preparation of the groups financial statements requires management to make judgments, estimates and assumptions that affect the reported amounts of revenues, expenses, assets and liabilities and the disclosure of contingent liabilities on the reporting date. However, uncertainty about these assumptions and estimates could result in outcomes that could require a material adjustment to the carrying amount of the asset or liability affected in the future. Assumptions used to make estimates are regularly reviewed. Changes in estimates only affecting one accounting period are only considered in that accounting period. In the case of changes in estimates that affect the current and future accounting periods, these are considered appropriately in the current and subsequent accounting periods.

Discussed below are the key judgments and assumptions concerning the future and other key sources of estimation and uncertainty on the balance sheet date that have a significant risk of causing a material adjustment to the carrying amounts of assets and liabilities within the next financial year.

Development expenses

Development expenses are capitalized in accordance with the accounting policy described in note (4). Initial capitalization of costs is based on management judgment assuming that technological and economic feasibility is confirmed, usually when a product development project has reached a defined milestone according to an established project management model. In determining the amounts to be capitalized, management makes assumptions regarding the expected future cash generation of the assets, discount rates to be applied and the expected period of benefits. See note (12) for the carrying amounts involved.

Impairment of non-financial assets

The group assesses whether there are any indicators of impairment for all non-financial assets on each reporting date. Goodwill and other indefinite life intangibles are tested for impairment annually and at other times when such indicators exist. Other nonfinancial assets are tested for impairment when there are indicators that the carrying amounts may not be recoverable. When value-in-use calculations are undertaken, management must estimate the expected future cash flows from the asset or cash generating unit and choose a suitable discount rate in order to calculate the present value of these cash flows. See note (11) and (12) for the carrying amounts involved.

Employee Benefits

Pension and similar post-employment obligations as well as the related expenses are recognized based on actuarial calculations. The actuarial valuation of the present value of pension obligations depends on a number of assumptions regarding the discount rate, the expected salary increase rate, the expected pension trend, and life expectancy. In the event that changes in the assumptions regarding the valuation parameters are required, the future amounts of the pension obligations as well as the pension benefit costs may be affected materially. For further details on the valuation of pension obligations, see note (17).

Share-based compensation transactions

The group measures the cost of share-based compensation instruments for employees by reference to the fair value of the instruments on the date at which they are granted or on the balance sheet date. Estimating fair value requires determining the most appropriate valuation model for a grant of share-based compensation instruments, which is dependent on the terms and conditions of the grant. This also requires determining the expected life of the option, volatility and dividend yield, as well as further assumptions. See note (31) for the carrying amounts involved.

Provisions

Significant estimates are involved in the determination of provisions related to warranty costs and legal proceedings a. The estimate of warranty claims is based on historic data and is extrapolated into the future. Legal proceedings often involve complex legal issues and are subject to substantial uncertainties. Accordingly, management exercises considerable judgment in determining whether there is a present obligation as a result of a past event at the end of the reporting period, whether it is more likely than not that such a proceeding will result in an outflow of resources and whether the amount of the obligation can be reliably estimated. Other provisions are described in note (17).

Transaction price for customer loyalty programs

Points accumulated for purchases provide a material right to customers that they would not receive without entering into a contract. The transaction price is allocated to the product and the points on a relative stand-alone selling price basis. Management estimates the selling price per point on the basis of the discount granted when the points are redeemed and on the basis of the likelihood of redemption, based on past experience.

Accounting for combined supply and service contracts

Adtran Networks provides contracts that have more than one separate performance obligation (multiple element arrangements). The transaction price is allocated to the performance obligations in the contract by reference to their relative standalone selling prices. If a standalone selling price is not directly observable Adtran Networks will need to estimate it. These estimates have a significant impact on the timing of revenue recognition.

Leases

In determining the lease term, management considers all facts and circumstances that create an economic incentive to exercise an extension option, or not exercise a termination option. Extension options (or periods after termination options) are only included in the lease term if the lease is reasonably certain to be extended (or not terminated).

Taxes

Uncertainties exist with respect to the interpretation of complex tax regulations and the amount and timing of future taxable income. Given the wide range of international business relationships and the long-term nature and complexity of existing contractual agreements, differences arising between the actual results and the assumptions made, or future changes to such assumptions, could necessitate future adjustments to tax income and expenses already recorded. The group establishes provisions, based on reasonable estimates, for possible consequences of audits by the tax authorities of the respective countries in which it operates. The amount of such provisions is based on various factors, such as experience of previous tax audits and differing interpretations of tax regulations by the taxable entity and the responsible tax authority. Such differences of interpretation may arise on a wide variety of issues depending on the conditions prevailing in the respective group company's domicile.

Deferred tax assets are recognized for all unused tax losses to the extent that it is probable that taxable profit will be available to utilize these losses. Significant management judgment is required to determine the amount of deferred tax assets that can be recognized, based upon the likely timing and level of future taxable profits together with future tax planning strategies. See note (25) for the carrying amounts involved.

Non-financial risks

The assessment of the impact of non-financial risks (global warming, circular economy, new regulations) on the recognition and measurement of assets and liabilities is based on significant management judgments and assumptions. Non-financial risks are assessed by management as long-term risks that currently have no significant impact on net realizable values, recoverable amounts, useful lives or the requirement to recognize provisions.

(5) Cash and cash equivalents

Cash and cash equivalents include current funds as well as current financial assets with a remaining maturity that does not exceed three months and that are readily convertible to a known amount of cash and only subject to an insignificant risk of changes in value.

On June 30, 2024, cash of EUR 3,404 thousand (December 31, 2023: EUR 2,545 thousand) held in China is subject to local exchange control regulations. These local regulations provide for restrictions on exporting capital from the country, other than through normal dividends.

Cash at banks earns interest at floating rates based on daily bank deposit rates.
Cash equivalents are invested for varying periods of between one day and three months, depending on the immediate cash requirements of the group, and earn interest at the respective short-term deposit rates.
(6) Trade accounts receivable

Trade accounts receivable are non-interest-bearing and are due within 30 to 120 days in general. For specific projects, other payment terms may be agreed.

Gross and net trade accounts receivable are as follows:

(in thousands of EUR) Jun. 30, 2024 Dec. 31, 2023

In Q4 2023, the group transitioned from a pre-existing factoring agreement to a joint receivable purchase and servicing agreement together with Adtran, Inc. as an additional seller. The new agreement results in the requirement to consolidate a special purpose entity which includes the sold trade receivables as well a financial liability.
(7) Inventories

In 6M 2024, impairment of inventories amounting to EUR 3,474 thousand (6M 2023: EUR 7,086 thousand) was recognized as an expense within cost of goods sold. This amount includes reversals of earlier write-downs amounting to EUR 1,775 thousand (6M 2023: EUR 932 thousand) due to higher selling and input prices.

In 6M 2024 and 6M 2023, material costs of EUR 82,625 thousand and EUR 176,129 thousand, respectively, have been recognized.
(8) Contract assets

Contract assets amounting to EUR 146 thousand (prior year: EUR 340 thousand) relate to claims from return deliveries. Contract assets are subject to the impairment requirements of IFRS 9, however the identified impairment losses were insignificant.

This 4th amendment to the previously existing agreement allows for a USD 100,000 thousand subline available for borrowings by Adtran Networks SE (the "subline"). At June 30, 2024, Adtran Networks SE has drawn USD 75,000 thousand out of this agreement. The loan matures on July 18, 2027 and can be repaid fully or in part at any time. As early repayment cannot be demanded by the lender, it is reported as non-current financial liability. At June 30, 2024, the variable interest rate for the loan amounts to $8.56 \%$ p.a. Interest expenses of EUR 450 thousand (USD 482 thousand) were accrued for the period from June 4, 2024 to the end of the current quarter. Moreover, Adtran Networks has paid upfront fees, arrangement fees and legal fees totaling EUR 520 thousand (USD 563 thousand) in connection with the closing of the Senior Secured Credit Facility. The fees will be expenses straight-line over the term of the underlying loan contract.

(25) Income tax

The tax expenses in 6M 2024 and 6M 2023 result from the application of the expected tax rate of the group to the current IFRS result. The expected tax rate is calculated based on a tax planning for the financial year. Tax income of EUR 13,985 thousand in the current reporting period is largely driven by the recognition of deferred tax assets on loss carryforwards (6M 2023: tax expense of EUR 2,921 thousand).

(26) Restructuring expenses

In 6M 2024, restructuring expenses amounting to EUR 4,464 thousand have been recognized (6M 2023: EUR 3,000 thousand), mainly related to severance agreements with employees.

(27) Consolidated cash flow statement

The consolidated cash flow statement has been prepared in accordance with IAS 7.
Cash and cash equivalents include short-term cash and short-term financial assets whose remaining maturity does not exceed three months. Bank overdrafts are reported in financial liabilities.

Cash flows from investing and financing activities are determined directly, whereas the cash flow from operating activities is derived indirectly from the consolidated income before tax. When cash flow from operating activities is calculated, the changes in assets and liabilities are adjusted for the effects of currency translation. As a result, it is not possible to reconcile the figures to the differences in the published consolidated statement of financial position.

The movements of liabilities from financing activities are as follows:

(in thousands of EUR) Lease liabilities Liabilities to banks Financial liabilities to Adtran Holdings, Inc. Total liabilities from financing activities
Jan. 1, 2023 21,202 56,430 - 77,632

Actual interest payments for liabilities to banks amounting to EUR 54 thousand (6M 2023: EUR 437 thousand), interest payments for financial liabilities to Adtran Holdings, Inc. amounting to EUR 848 thousand (6M 2023: EUR 955 thousand) and interest related to lease liabilities of EUR 709 thousand (6M 2023: EUR 306 thousand) are included in cash flow from financing activities.

Non-cash changes include effective interest rate changes on liabilities to banks as well as non-cash effective increases or decreases in lease liabilities due to consideration of new lease contracts or disposal of lease contracts.

Cash and cash equivalents to which the group only has restricted access are explained in note (5).
(28) Segment reporting

In accordance with IFRS 8, operating segments are identified based on the way information is reported internally to the chief operating decision maker, i.e. the management board, and regularly reviewed to make decisions about resources to be assigned to the segment and assess its performance. The internal organizational and management structure and the structure of internal financial reporting activities are the key factors in determining what information is reported. For making decisions about resource allocation and performance assessment, management does not monitor the operating results separately on the level of business units. Therefore the reporting on individual business segment does not apply.

Within the Adtran Networks group, management decisions are based on pro forma EBIT. Pro forma financial information excludes non-cash charges related to share-based compensation plans and amortization and impairment of goodwill and acquisition-related intangible assets. Additionally, expenses related to M\&A and restructuring measures are not included. Income from capitalization of development expenses is shown as a separate line item and not deducted from research and development expenses.

This document contains forward-looking statements using words such as "believes", "anticipates" and "expects" to describe expected revenues and earnings, anticipated demand for optical networking solutions, internal estimates and liquidity. These forward-looking statements are based on the beliefs of the management board and respective assumptions made, and involve a number of unknown risks, uncertainties and other factors, many of which are beyond Adtran Networks' control. If one or more of these uncertainties or risks materializes, or if the underlying assumptions of the management board prove incorrect, actual results can differ materially from those described in or inferred from forward-looking statements and information. Adtran Networks' supply chain has been affected by the global semiconductor crisis: component delivery times have increased significantly and, despite many countermeasures, Adtran Networks' delivery times to customers are also increasing. Although potential future component bottlenecks are systematically identified and analyzed, and supply chain management actively counteracts them, the risk remains that not all customers can be supplied within a timeframe that is satisfactory to them. In addition, the management board sees short-term risks on the purchasing side, as delivery times have already been reduced and customers are actively managing their own inventories. There is therefore a risk that customers will currently order less and reduce their inventories. All risks and uncertainties remain unchanged and are explained in the "risk and opportunity report" section of the Group Management Report 2023.
