| **To the Management of**<br> **Comtrafo Ind**ú**stria de Transformadores** <br> Elétricos S.A. Cornélio Procópio – Paraná |
| **Qualified opinion** |
| We have audited the consolidated financial statements of Comtrafo Indústria de Transformadores Elétricos S.A. and its subsidiaries ("The Group"), which comprise the consolidated statement of financial position as of December 31, 2024 and the related consolidated statements of profit or loss and other comprehensive income, changes in shareholders' equity, and cash flows for the year then ended, and the related notes to the consolidated financial statements.<br> In our opinion, except for the omissions of the information described in the Basis for Qualified Opinion section of our report, the accompanying consolidated financial statements present fairly, in all material respects, the financial position of the Group as of December 31, 2024, and the results of its operations and its cash flows for the years then ended in accordance with IFRS Accounting Standards as issued by the International Accounting Standards Board (IFRS Accounting Standards). |
| **Basis for Qualified Opinion** |
| As discussed in Note 3, the accompanying consolidated financial statements are not presented in accordance with International Accounting Standard 1 – Presentation of Financial Statements, as they do not include comparative figures, which constitute a departure from IFRS Accounting Standards as issued by the International Accounting Standards Board (IFRS Accounting Standards).<br> We conducted our audit in accordance with auditing standards generally accepted in the United States of America (GAAS). Our responsibilities under those standards are further described in the Auditor's Responsibilities for the Audit of the Consolidated financial statements section of our report. We are required to be independent of the Group and to meet our other ethical responsibilities, in accordance with the relevant ethical requirements relating to our audit. We believe that the audit evidence we have obtained is sufficient and appropriate to provide a basis for our qualified audit opinion. |

| **Responsibilities of Management for the Consolidated Financial Statements** |
| Management is responsible for the preparation and fair presentation of the consolidated financial statements in accordance with IFRS Accounting Standards, and for the design, implementation, and maintenance of internal control relevant to the preparation and fair presentation of consolidated financial statements that are free from material misstatement, whether due to fraud or error.<br> In preparing the consolidated financial statements, management is required to evaluate whether there are conditions or events, considered in the aggregate, that raise substantial doubt about the Group's ability to continue as a going concern for one year after the date that the consolidated financial statements are issued. |
| **Auditors**' **Responsibilities for the Audit of the Consolidated financial statements** |
| Our objectives are to obtain reasonable assurance about whether the consolidated financial statements as a whole are free from material misstatement, whether due to fraud or error, and to issue an auditor's report that includes our opinion. Reasonable assurance is a high level of assurance but is not absolute assurance and therefore there is not a guarantee that an audit conducted in accordance with GAAS will always detect a material misstatement when it exists. The risk of not detecting a material misstatement resulting from fraud is higher than for one resulting from error, as fraud may involve collusion, forgery, intentional omissions, misrepresentations, or the override of internal control. Misstatements are considered material if there is a substantial likelihood that, individually or in the aggregate, they would influence the judgment made by a reasonable user based on the consolidated financial statements.<br> In performing an audit in accordance with GAAS, we:<br> - Exercise professional judgment and maintain professional skepticism throughout the audit.<br> - Identify and assess the risks of material misstatement of the consolidated financial statements, whether due to fraud or error, and design and perform audit procedures responsive to those risks. Such procedures include examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements.<br> - Obtain an understanding of internal control relevant to the audit in order to design audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of Group's internal control. Accordingly, no such opinion is expressed.<br> - Evaluate the appropriateness of accounting policies used and the reasonableness of significant accounting estimates made by management, as well as evaluate the overall presentation of the consolidated financial statements.<br> - Conclude whether, in our judgment, there are conditions or events, considered in the aggregate, that raise substantial doubt about the Group's ability to continue as a going concern for a reasonable period of time.<br> We are required to communicate with management regarding, among other matters, the planned scope and timing of the audit, significant audit findings, and certain internal control related matters that we identified during the audit.<br>/s/ KPMG Auditores Independentes Ltda.<br> Londrina - Paraná, Brazil<br> February 17, 2026 |

| **3** | **Basis of accounting** |

---

The consolidated financial statements have been prepared in accordance with IFRS Accounting Standards as issued by the International Accounting Standards Board ("IFRS Accounting Standards") except for the fact that the consolidated financial statements are not presented in accordance with International Accounting Standard 1 – Presentation of Financial Statements, as they do not include comparative figures, which constitute a departure from IFRS Accounting Standards

The issuance of the consolidated financial statements was authorized by the Group's management on February 17, 2026.

Details on the Group's accounting policies are shown in Note 7.

---

| | |
|:---|:---|
| **4** | **Functional and presentation currency** |

---

These consolidated financial statements are presented in Brazilian reais, which is the functional currency of the Company and its subsidiaries. All amounts have been rounded to the nearest thousand, unless otherwise indicated.

---

| | |
|:---|:---|
| **5** | **Use of judgements and estimates** |

---

In preparing these consolidated financial statements, management has made judgments and estimates about the future, that affect the application of accounting principles of the Group, and the reported amounts of assets, liabilities, revenues and expenses. Actual results may differ from these estimates.

Estimates and underlying assumptions are reviewed on an ongoing basis. Revisions to accounting estimates are recognized prospectively.

&nbsp;&nbsp;&nbsp;&nbsp;**a.** **Judgments** 

Information about judgments made in applying the accounting policies that have the most significant effects on the amounts recognized in the consolidated financial statements is included in the following note:

● Note 19 - recognition of provisions for contingencies: determining if there is a present obligation with probable likelihood of outflow of resources to settle the obligations.

&nbsp;&nbsp;&nbsp;&nbsp;**b.** **Assumptions and estimation uncertainties** 

Information about assumptions and estimation uncertainties as of December 31, 2024, that have a significant risk of resulting in a material adjustment to the carrying amounts of assets and liabilities within the next financial year is included in the following notes:

● Note 18 – Recognition of deferred tax assets: availability of future taxable profits against which deductible temporary differences and tax losses carried forward can be utilized.

● Note 10 – Key assumptions in determining the measurement of the impairment loss on trade receivables; and

● Note 19 - measurement of provisions for contingencies: main assumptions regarding the magnitude of the outflows of funds.

&nbsp;&nbsp;&nbsp;&nbsp;**c.** **Measurement of fair values** 

A number of the Group's accounting policies and disclosures require the measurement of fair value for both financial and non-financial assets and liabilities.

The Group established a control structure related to measurement of fair value.

When measuring fair value of an asset or liability, the Group uses observable data as much as possible. Fair values are classified at different levels according to hierarchy based on information (inputs) used in valuation techniques, as follows:

● **Level 1:** Quoted prices (unadjusted) in active markets for identical assets or liabilities.

● **Level 2:** Inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly (prices) or indirectly (derived from prices).

● **Level 3:** Inputs for the asset or liability that are not based on observable market data (unobservable inputs).

The Group recognizes transfers between levels of the fair value hierarchy at the end of the reporting period in which the changes occur.

---

| | |
|:---|:---|
| **6** | **Basis of measurement** |

---

The consolidated financial statements have been prepared on the historical cost basis, except for derivative financial instruments, which are measured at fair value at each reporting date and changes in fair value are recognized in the statement of profit or loss.

---

| | |
|:---|:---|
| **7** | **Material accounting policies** |

---

The material accounting policies applied in these consolidated financial statements are described below:

&nbsp;&nbsp;&nbsp;&nbsp;**a.** **Basis of consolidation** 

&nbsp;&nbsp;&nbsp;&nbsp;***(i)***  ***Subsidiaries*** 

The Group controls an entity when it is exposed to, or has rights to, variable returns from its involvement with the entity and has the ability to affect those returns through its power over the entity. The consolidated financial statements of subsidiaries are included in the consolidated financial statements from the date on which the Group obtains control, until the date on which control ceases.

&nbsp;&nbsp;&nbsp;&nbsp;***(ii)***  ***Transactions eliminated on consolidation*** 

Intra-group balances and transactions, and any unrealized income or expenses arising from intra-Group transactions, are eliminated.

&nbsp;&nbsp;&nbsp;&nbsp;***(iii)***  ***Non-controlling interests account policy*** 

Changes in the Group's ownership interest in a subsidiary that do not result in a loss of control are accounted for as equity transactions.

------

&nbsp;&nbsp;&nbsp;&nbsp;**b.** **Foreign currency** 

&nbsp;&nbsp;&nbsp;&nbsp;***(i)***  ***Foreign currency transactions*** 

Foreign currency transactions are translated into Brazilian reais, which is the functional currency of the Group, at the exchange rates prevailing at the dates of the transactions.

Monetary assets and liabilities denominated in foreign currencies at the reporting date are retranslated into the functional currency at the exchange rates at the reporting date. Non-monetary items that are measured based on historical cost in a foreign currency are translated using the exchange rates at the dates of the transactions. Foreign exchange differences arising on translation are generally recognized in profit or loss

&nbsp;&nbsp;&nbsp;&nbsp;**c.** **Revenue** 

The Group's revenue is generated primarily from three operating activities: (i) the sale of power transformers and related components in both domestic and international markets; (ii) the resale of electrical materials through retail operations; and (iii) the provision of electrical installation services. See Note 22 for detailed information on performance obligations and revenue recognition.

&nbsp;&nbsp;&nbsp;&nbsp;**d.** **Short-term employee benefits** 

Short-term employee benefit obligations are recognized as personnel expenses as the related services are rendered. A liability is recognized for the amount expected to be paid if the Group has a present legal or constructive obligation to pay this amount as a result of past service provided by employees and the obligation can be reliably estimated.

&nbsp;&nbsp;&nbsp;&nbsp;**e.** **Finance income and finance expenses** 

The Group finance income and finance expenses comprise:

● Interest income;

● Interest expense;

● Foreign exchange gains and losses on financial assets and liabilities; and

● Gains and losses on derivatives instruments transactions.

Interest income and interest expense are recognized in profit or loss using the effective interest method.

The 'effective interest rate' is the rate that estimated future cash payments or receipts through the expected life of the financial instrument to:

● the gross carrying amount of the financial asset; or

● the amortized cost of the financial liability.

------

In calculating interest income and expense, the effective interest rate is applied to the gross carrying amount of the financial asset (when the asset is not credit-impaired) or to the amortized cost of the liability. However, for financial assets that have become credit-impaired subsequent to initial recognition, interest income is calculated by applying the effective interest rate to the amortized cost of the financial asset. If the asset is no longer credit-impaired, then the calculation of interest income reverts to the gross basis.

&nbsp;&nbsp;&nbsp;&nbsp;**f.** **Income tax and social contribution** 

Current and deferred income tax and social contribution are calculated based on the statutory tax rates of 15%, plus a 10% surplus on taxable profit exceeding R$240 (annual basis) for income tax purposes, and 9% on taxable profit for social contribution on net income, taking into account the offset of tax losses and negative tax bases for social contribution, limited to 30% of the taxable profit for the year.

Income tax and social contribution expense comprises current and deferred income tax and social contribution. Current and deferred taxes are recognized in profit or loss unless they relate to a business combination or to items recognized directly in equity or in other comprehensive income.

&nbsp;&nbsp;&nbsp;&nbsp;***(i)***  ***Current tax*** 

Current tax expense represents the estimated tax payable or recoverable on the taxable profit or loss for the year, including any adjustments to tax payable in respect of prior years. The amount of current tax payable or recoverable is recognized in the statement of financial position as a tax asset or liability based on the best estimate of the amount expected to be paid to or recovered from the tax authorities, reflecting any uncertainties related to its determination, if applicable. Current tax is measured using tax rates enacted or substantively enacted at the reporting date.

Current tax assets and liabilities are offset only when certain criteria are met.

&nbsp;&nbsp;&nbsp;&nbsp;***(ii)***  ***Deferred tax*** 

Deferred tax assets and liabilities are recognized for temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and their corresponding tax basis. Changes in deferred tax assets and liabilities during the year are recognized as deferred income tax and social contribution expense.

Deferred tax assets are recognized in respect of deductible temporary differences and unused tax losses to the extent that it is probable that future taxable profits will be available against which they can be utilized. Deferred tax assets are reviewed at each reporting date and are reduced to the extent that it is no longer probable that the related tax benefit will be realized. Deferred tax assets and liabilities are measured using the tax rates expected to apply to the temporary differences when they reverse, based on tax rates that have been enacted or substantively enacted by the reporting date.

The measurement of deferred tax assets and liabilities reflects the tax consequences that would follow from the manner in which the Group expects, at the reporting date, to recover or settle the carrying amount of its assets and liabilities.

Deferred tax assets and liabilities are offset only when certain criteria are met.

------

&nbsp;&nbsp;&nbsp;&nbsp;**g.** **Inventories** 

Inventories are measured at the lower of cost and net realizable value. The cost of inventories is based on the weighted average cost method and includes expenditures incurred in the acquisition of inventories, production and conversion costs, and other costs incurred in bringing inventories to their present location and condition. In the case of work in progress inventories, cost includes an allocation of manufacturing overheads based on normal operating capacity.

The net realizable value is the estimated selling price in the ordinary course of business, less the estimated costs of completion and the estimated costs necessary to make the sale.

&nbsp;&nbsp;&nbsp;&nbsp;**h.** **Property, plant and equipment** 

&nbsp;&nbsp;&nbsp;&nbsp;***(i)***  ***Recognition and measurement*** 

Items of property, plant and equipment are measured at historical cost of acquisition or construction, less accumulated depreciation and any accumulated impairment losses (if any).

When significant parts of an item of property, plant and equipment have different useful lives, they are accounted for as separate items (major components) of property, plant and equipment.

Any gains or losses arising from the disposal of an item of property, plant and equipment are recognized in profit or loss.

&nbsp;&nbsp;&nbsp;&nbsp;***(ii)***  ***Subsequent expenditure*** 

Subsequent expenditures are capitalized only when it is probable that future economic benefits associated with the expenditure will flow to the Group and the cost can be measured reliably. All other subsequent expenditure is recognized in profit or loss as incurred.

&nbsp;&nbsp;&nbsp;&nbsp;***(iii)***  ***Depreciation*** 

Depreciation is calculated to write off the cost of items of property, plant and equipment, net of their estimated residual values, on a straight-line basis over their estimated useful lives. Depreciation is recognized in profit or loss. Land is not depreciated.

The estimated useful lives of property, plant and equipment are as follows:

---

| | |
|:---|:---|
|  | **Years of** <br> **useful lives** |
| Vehicles | 04 years |
| Commercial Installations | 10 years |
| Machinery and equipment | 10 years |
| Furniture and fixtures | 10 years |
| IT equipment | 6 – 7 years |
| Communication equipment | 6 – 7 years |
| Tools and accessories | 10 years |

---

&nbsp;&nbsp;&nbsp;&nbsp;**i.** **Financial instruments** 

&nbsp;&nbsp;&nbsp;&nbsp;***(i)***  ***Initial recognition and measurement*** 

Financial assets and financial liabilities are initially recognized when the Group becomes a party to the contractual provisions of the instrument.

------

A financial asset (unless it is a trade receivable without a significant financing component) or financial liability is initially measured at fair value plus or minus, for items not measured at fair value through profit or loss (FVTPL), transaction costs that are directly attributable to its acquisition or issuance. Trade receivables without a significant financing component are initially measured at the transaction price.

&nbsp;&nbsp;&nbsp;&nbsp;***(ii)***  ***Classification and subsequent measurement*** 

*Financial assets - classification*

On initial recognition, a financial asset is classified as subsequently measured at: amortized cost or FVTPL.

Financial assets are not subsequently reclassified after initial recognition unless the Group changes its business model for managing financial assets. In such case, all affected financial assets are reclassified on the first day of the reporting period following the change in the business model.

A financial asset is measured at amortized cost if it meets both of the following conditions and is not designated as measured at fair value through profit or loss (FVTPL):

● it is held within a business model whose objective is to hold financial assets in order to collect contractual cash flows; and

● its contractual terms give rise, on specified dates, to cash flows that are solely payments of principal and interest (SPPI) on the principal amount outstanding.

All financial assets, except for derivative financial instruments which are measured at FVTPL, are measured at amortized cost.

*Financial assets* – *Business model assessment*

The Group maintains a single business model for all of its financial assets, which is solely to hold such assets in order to collect the related contractual cash flows. Under this business model, financial assets are managed with the objective of collecting contractual cash flows over the life of the instrument, and not for the purpose of selling them. Accordingly, all financial assets are evaluated for classification and measurement based on the Group's intention and ability to hold these assets to collect contractual cash flows that are solely payments of principal and interest ("SPPI").

*Financial assets* – *subsequent measurement and gains and losses*

---

| | |
|:---|:---|
| Financial assets measured at amortized cost | These assets are subsequently measured at amortized cost using the effective interest method. Amortized cost is reduced by impairment losses. Interest income, foreign exchange gains and losses, and impairment losses are recognized in profit or loss. Any gain or loss on derecognition is recognized in profit or loss. |
| Financial assets at FVTPL | These assets are subsequently measured at fair value. Net gains and losses, including any interest are recognized in profit or loss. |

---

------

*Financial liabilities* – *classification, subsequent measurement and gains and losses*

Financial liabilities are classified and measured as amortized cost, except for derivative financial instruments, which are measured at fair value at each reporting date and changes in fair value are recognized in the statement of profit or loss.

Financial liabilities (other than derivative financial instruments) are subsequently measured at amortized cost using the effective interest method. Interest expense, foreign exchange gains and losses are recognized in statement of profit or loss. Any gain or loss on derecognition is also recognized in statements of profit or loss.

&nbsp;&nbsp;&nbsp;&nbsp;***(iii)***  ***Derecognition*** 

*Financial assets*

The Group derecognizes a financial asset when the contractual rights to the cash flow of the asset expire, or when the Group transfers the rights to receive the contractual cash flows over a financial asset in a transaction in which essentially all the risks and rewards of ownership of the financial asset are transferred or in which the Group neither transfers or maintains all ownership risks and rewards of the financial assets and also does not hold the control over the financial asset.

*Financial liabilities*

The Group derecognizes a financial liability when its contractual obligation is discharged, cancelled or expires. A financial liability is also derecognized when its terms are modified and the cash flows of the modified liability are substantially different, in which case a new financial liability based on the modified terms is recognized at fair value.

On derecognition of a financial liability, the difference between the carrying amount extinguished and the consideration paid (including non-cash assets transferred or liabilities assumed) is recognized in profit or loss.

&nbsp;&nbsp;&nbsp;&nbsp;***(iv)***  ***Offseting*** 

Financial assets and financial liabilities are offset and the net amount is presented in the statement of financial position when, and only when, the Group currently has a legally enforceable right to set off the recognized amounts and intends either to settle on a net basis or to realize the asset and settle the liability simultaneously.

&nbsp;&nbsp;&nbsp;&nbsp;***(v)***  ***Derivative financial instruments*** 

The Group holds derivative financial instruments to hedge its exposure to risks of foreign currency changes.

Derivatives are initially measured at fair value. After the initial recognition, derivatives are measured at fair value and changes are recorded in statement of profit or loss.

------

&nbsp;&nbsp;&nbsp;&nbsp;**j.** **Impairment** 

&nbsp;&nbsp;&nbsp;&nbsp;***(i)***  ***Non-derivative financial assets*** 

*Financial instruments*

The Group recognizes Impairment loss on trade accounts receivables for expected credit losses on:

● Financial assets measured at amortized cost (trade and other receivables).

The Group measures impairment loss on trade receivables at an amount equal to expected credit losses for life, except for items described below, which are measured as expected credit loss for 12 months: and

● Other debt securities and bank balances for which the credit risk (i.e., default risk throughout the expected life of financial instrument) has not significantly increased since the beginning of initial recognition.

Impairment loss on trade accounts receivables are measured at a value equal to an expected credit loss for the instrument's entire life.

When determining if the credit risk of a financial asset has significantly increased since the initial recognition and when estimating expected credit losses, the Group considers reasonable and tolerable information that is relevant and available without excessive cost or effort. This includes quantitative and qualitative information and analysis, based on the Group's historical experience, credit assessment, and considering prospective information (forward-looking).

The Group assumes that the credit risk in a financial asset increased significantly if it is more than 360 days overdue.

The Group considers a financial asset in default when:

● It is highly unlikely that the debtor will fully meet its credit obligations to the Group without the Group needing to enforce collateral or take similar recovery actions.; or

● Financial asset is past due for more than 360 days.

*Measurement of impairment losses*

Impairment losses are estimates weighted by likelihood of credit loss. Credit losses are measured at present value based on all cash insufficiencies (that is, the difference between the cash flows owed to the Group in accordance with the contract and the cash flows that the Group expects to receive).

*Financial assets with recovery issues*

On each reporting date, the Group evaluates whether the financial assets accounted for at amortized cost are experiencing recovery problems. A financial asset has "recovery problems" when one or more events with a negative impact on the estimated future cash flows of the financial asset occur.

------

Objective evidence that financial assets had recovery problems includes the following observable data:

● Significant financial difficulties of the customer;

● Breach of contractual clauses, such as delinquency or late payment of more than 360 days;

● Restructuring of an amount due to the Group under conditions that would not be accepted in normal conditions;

● The probability that the borrower will enter bankruptcy or other financial reorganization; or

● The disappearance of an active market for that financial asset because of financial difficulties.

*Presentation of allowance for expected credit losses on financial position.*

Allowance for expected credit losses in financial assets measured at amortized cost are deducted from the gross carrying amount of the assets.

&nbsp;&nbsp;&nbsp;&nbsp;***(ii)***  ***Non-financial assets*** 

At each reporting date, the Group reviews the carrying amounts of its non-financial assets (except for inventories and deferred tax assets) to determine whether there is any indication of impairment.

For impairment tests, assets are grouped into the cash generating units (CGUs), that is, smallest identifiable group of assets that can generate cash inflows by continuous use, which are highly independent from cash inflows referring to other assets or cash generating units.

Recoverable value of an asset or CGU is the higher of value in use and fair value less selling costs. Value in use is based on estimated future cash flows discounted to present value using a discount rate before taxes that reflects current market evaluations of times value of money and the specific risks of the assets or CGU.

An impairment loss is recognized when the carrying amount of an asset or its CGU exceeds its recoverable value.

Impairment losses are recognized in profit or loss.

&nbsp;&nbsp;&nbsp;&nbsp;**k.** **Provisions** 

Provisions are recognized when the Group has a present obligation, as a result of past events, and it is likely that an outflow of funds will be necessary to settle the obligation.

Provisions for lawsuits are recorded based on best estimates of risk involved and are established at amounts considered sufficient to cover probable losses. The lawsuits estimated as possible losses are disclosed in the notes and those estimated as remote losses are neither provisioned nor disclosed.

Tax, civil and labor contingencies subject to judicial disputes are reassessed periodically and accounted for based on management assessment, supported by opinions of legal counsel and regarding the probable outcome of the legal proceedings at the reporting dates.

------

&nbsp;&nbsp;&nbsp;&nbsp;**l.** **Leases** 

At inception of a contract, the Group determines whether a contract is, or contains, a lease.

A contract is, or contains, a lease if it conveys the right to control the use of an identified asset for a period of time in exchange for consideration.

***As a lessee***

At commencement or modification of a contract that contains a lease component, the Group allocates the consideration in the contract to each lease component based on their relative stand-alone prices. However, for leases of property, the Group has elected not to separate non-lease components and accounts for the lease and non-lease components as a single lease component.

The Group recognizes a right-of-use asset and a lease liability at the lease commencement date. The right-of-use asset is initially measured at cost, which comprises the initial measurement of the lease liability, adjusted for any lease payments made at or before the commencement date, plus any initial direct costs incurred by the lessee and an estimate of costs to be incurred by the lessee in dismantling and removing the underlying asset, restoring the site on which it is located or restoring the underlying asset to the condition required by the terms and conditions of the lease, less any lease incentives received.

The right-of-use asset is subsequently depreciated using the straight-line method from the commencement date to the earlier of the end of the lease term or the end of the useful life of the right-of-use asset, unless the lease transfers ownership of the underlying asset to the lessee by the end of the lease term or the cost of the right-of-use asset reflects that the lessee will exercise a purchase option. In such cases, the right-of-use asset is depreciated over the useful life of the underlying asset, which is determined on the same basis as for property, plant and equipment. In addition, the right-of-use asset is periodically reduced by impairment losses, if any, and adjusted for certain remeasurements of the lease liability.

The lease liability is initially measured at the present value of the lease payments that are not paid at the commencement date, discounted using the interest rate implicit in the lease or, if that rate cannot be readily determined, the Group's incremental borrowing rate. the Group generally uses its incremental borrowing rate as the discount rate.

The Group determines its incremental borrowing rate by obtaining interest rates from various external financing sources and making adjustments to reflect the terms of the lease contract and the type of the leased asset.

Lease payments included in the measurement of the lease liability comprise the following:

● fixed payments, including in-substance fixed payments;

● variable lease payments that depend on an index or a rate, initially measured using the index or rate as at the commencement date;

● amounts expected to be payable by the lessee under residual value guarantees; and

● • the exercise price of a purchase option if the lessee is reasonably certain to exercise that option, and payments of penalties for terminating the lease, if the lease term reflects the lessee exercising an option to terminate the lease.

The lease liability is subsequently measured at amortized cost using the effective interest method. It is remeasured when there is a change in future lease payments resulting from a change in an index or a rate, when there is a change in the amounts expected to be payable under a residual value guarantee, when the Group changes its assessment of whether it will exercise a purchase, extension or termination option, or when there is a revised in-substance fixed lease payment.

When the lease liability is remeasured in this manner, a corresponding adjustment is made to the carrying amount of the right-of-use asset, or is recognized in profit or loss if the carrying amount of the right-of-use asset has been reduced to zero.

From January 1, 2021, to the extent that the basis for determining future lease payments changes as required by the interest rate benchmark reform, the Group remeasures the lease liability by discounting the revised lease payments using a revised discount rate that reflects the change to an alternative benchmark interest rate.

***Short-term leases and leases of low-value assets***

The Group has elected not to recognize right-of-use assets and lease liabilities for leases of low-value assets and short-term leases, including IT equipment. The Group recognizes the lease payments associated with these leases as an expense on a straight-line basis over the lease term.

&nbsp;&nbsp;&nbsp;&nbsp;**m.** **Fair value measurement** 

'Fair value' is the price that would be received to sell an asset or paid for the transfer of a liability in an orderly transaction between market participants at the measurement date, on the primary market or, in the absence thereof, on the most advantageous market to which the Group has access on such date. The fair value of a liability reflects its risk of default (non-performance).

A number of the Group's accounting policies and disclosures require the measurement of fair values, for both financial and non-financial assets and liabilities.

When one is available, the Group measures the fair value of an instrument using the price quoted in an active market for that instrument. A market is regarded as 'active' if the transactions for the asset or liability take place with sufficient frequency and volume to provide pricing information on an ongoing basis.

If there is no quoted price in an active market, then the Group uses valuation techniques that maximise the use of relevant observable inputs and minimize the use of unobservable inputs. The chosen valuation technique incorporates all of the factors that market participants would take into account in pricing a transaction.

If an asset or a liability measured at fair value has a purchase and a selling price, the Group measures the assets based on purchase prices and liabilities based on selling prices. The chosen valuation technique incorporates all the factors market participants would take into account when pricing a transaction.

------

The best evidence of fair value of a financial instrument at initial recognition is normally the transaction price – i.e. the fair value of the consideration given or received. If the Group determines that fair value at initial recognition differs from transaction price and fair value is not evidenced, not even by price quoted in an active market for an identical asset or liability, neither based on valuation technique for which non-observable data is judged as insignificant for measurement, then financial instrument is initially measured at adjusted fair value, to distinguish the difference between fair value at initial recognition and transaction price. This difference is subsequently recognized in statement of profit or loss on an appropriate basis over the life of the instrument, or until such time when its valuation is fully supported by observable market data or the transaction is closed, whichever comes first.

| **8** | **Accounting standards issued but not yet effective** |

---

A number of new accounting standards are effective for annual reporting periods beginning after 1 January 2024, but earlier application was not permitted. Therefore, the Group has not early adopted the following new or amended accounting standards in the preparation of these consolidated financial statements

**IFRS 18 Presentation and Disclosure in Consolidated financial statements**

IFRS 18 will replace IAS 1 Presentation of Consolidated financial statements and applies for annual reporting periods beginning on or after 1 January 2027. The new accounting standard introduces the following key new requirements.

Entities are required to classify all income and expenses into five categories in the statement of profit or loss, namely the operating, investing, financing, discontinued operations and income tax categories. Entities are also required to present a newly-defined operating profit subtotal. Entities' net profit will not change.

Management-defined performance measures (MPMs) are disclosed in a single note in the consolidated financial statements.

Enhanced guidance is provided on how to group information in the consolidated financial statements.

In addition, all entities are required to use the operating profit subtotal as the starting point for the statement of cash flows when presenting operating cash flows under the indirect method.

The Group is still in the process of assessing the impact of the new accounting standard, particularly with respect to the structure of the Group's statement of profit or loss, the statement of cash flows and the additional disclosures required for MPMs. The Group is also assessing the impact on how information is grouped in the consolidated financial statements, including for items currently labelled as 'other'.

**Other accounting standards**

The following new and amended accounting standards are not expected to have a significant impact on the Group's consolidated financial statements:

● Classification and Measurement of Financial Instruments (Amendments to IFRS 9 and IFRS 7); *and* 

● Contracts Referencing Nature-dependent Electricity (Amendments to IFRS 9 and IFRS 7).

● Lack of Exchangeability – Amendments to IAS 21.

● Classification and Measurement of Financial Instruments – Amendments to IFRS 9 and IFRS 7, effective for annual reporting periods beginning on January 1, 2026;

● Contracts Referencing Nature-dependent Electricity – Amendments to IFRS 9 and IFRS 7;

● Annual Improvements to IFRS Accounting Standards – Volume 11;

● IFRS 19 Subsidiaries without Public Accountability: Disclosures; and

● Sale or Contribution of Assets between an Investor and its Associate or Joint Venture – Amendments to IFRS 10 and IAS 28, with an effective date to be determined.

&nbsp;&nbsp;&nbsp;&nbsp;(i) The Group benefits from state tax incentives related to ICMS (State VAT), which are classified as subventions for investment pursuant to Complementary Law No. 160/2017. This legislation established that incentives and tax benefits granted by the Brazilian states, including presumed ICMS credits and other fiscal-financial mechanisms, qualify as investment subsidies when intended to support the implementation or expansion of economic activities. As permitted by LC 160/2017, the Group excludes from the income tax basis the amounts corresponding to these ICMS incentives, which are recorded in a specific equity reserve ("tax incentive reserve") and are not available for distribution to shareholders. The related tax effects are reflected in the Group's current and deferred income taxes, as applicable.

&nbsp;&nbsp;&nbsp;&nbsp;**b.** **Reconciliation and changes in deferred income tax and social contribution** 

Changes in deferred taxes for year ended December 31, 2024 are detailed below:

&nbsp;&nbsp;&nbsp;&nbsp;(i) The Group determines its current income tax expense based on quarterly taxable income. In the fourth quarter of 2024, the Group generated a taxable loss, which may only be utilized as a deduction against taxable profits in future periods. Therefore, the Company recognized a deferred tax asset related to tax loss carryforwards in the amount of R$11,425.

Deferred tax assets and liabilities arising from temporary differences are recognized to the extent that it is probable that taxable profit will be available against which the deductible temporary differences can be utilized. The realization of these deferred tax balances will occur as the underlying temporary differences reverse in future periods, in accordance with the expected pattern of recovery or settlement of the related assets and liabilities.

In addition, based on projections of future taxable income, management recognized in 2024 the tax loss carryforwards related to the fourth quarter of 2024 and expects to realize the corresponding deferred tax assets within the next fiscal years.

The assessment of the recoverability of deferred tax assets is based on forecasts of taxable profits, which incorporate a number of financial and business assumptions as of the reporting date. Accordingly, these estimates are subject to uncertainty and may differ from actual results due to the inherent uncertainty associated with such projections.

Management reviews these assumptions on a periodic basis and, when necessary, adjusts the carrying amounts of deferred tax assets to reflect the expected level of realization.

| **19** | **Provision for labor and civil risks** |

---

The Group is involved in tax, labor and civil legal proceedings at various stages of litigation. Where applicable, these matters are supported by judicial deposits. Management, based on assessments performed with the support of external and internal legal advisors, recognizes provisions for those contingencies for which a present obligation exists and the risk of loss is considered probable.

The measurement of such provisions reflects the best estimate of the expenditure required to settle the present obligation at the reporting date, incorporating the uncertainties inherent in the outcome of these proceedings. Management also updates these estimates periodically to reflect new facts, legal developments, and the most current information available.

Below is presented the amount of provision for labor and other risks for years ended December 31, 2024:

&nbsp;&nbsp;&nbsp;&nbsp;**b.** **Tax incentive reserves** 

Brazilian Law No. 11,638/2007 introduced Article 195-A into Law No. 6,404/1976, which allows entities to appropriate the portion of net profit arising from government grants for investment to a Tax Incentive Reserve.

In this context, an entity may, in each reporting period, transfer from profit for the year to the tax incentive reserve an amount corresponding to the government grant received, so that such amount is not distributed as profits or dividends to shareholders. The adoption of this procedure is essential to ensure that government grants for investment are not subject to income tax (IRPJ) and social contribution (CSLL).

Accordingly, as the amounts arising from government grants were properly recognized in profit or loss for the period and included in retained earnings, The Group transferred the corresponding amount to the tax incentive Reserve, thereby meeting the applicable legal requirements. In 2024, the full amount of the government grant utilized was appropriated to the tax incentive reserve, totaling R$17,803.

&nbsp;&nbsp;&nbsp;&nbsp;**c.** **Legal reserve** 

The legal reserve is appropriated at 5% of profit for the year, up to the maximum limit of 20% of paid-in share capital, and is intended to ensure the integrity of share capital. This reserve may only be used to increase share capital or to offset accumulated losses.

&nbsp;&nbsp;&nbsp;&nbsp;**d.** **Working capital reserve** 

The working capital reserve is constituted in accordance with Article 38, paragraph 23, of The Group's Bylaws and is intended to support investments in non-current assets and increases in working capital, including through the amortization of The Group's indebtedness.

&nbsp;&nbsp;&nbsp;&nbsp;**e.** **Profit retention reserve** 

In accordance with Articles 197 and 202 of Law No. 6,404/1976, Management proposes the appropriation of the remaining balance of accumulated profits to the profit retention reserve.

------

&nbsp;&nbsp;&nbsp;&nbsp;**f.** **Distribution of dividends and interest on equity** 

Management ensures the distribution of profits to shareholders in the form of dividends, in accordance with Law No. 6,404/1976, at a minimum of 25% of profit for the year, after the appropriation to the legal reserve.

For the year ended December 31, 2024, shareholders approved total dividends of R$39,033, an amount that exceeds the mandatory minimum. Such amounts were paid in 2024.

In addition, interest on equity in the amount of R$36,766 was distributed, as presented below:

&nbsp;&nbsp;&nbsp;&nbsp;**b.** **Measurement of fair value** 

***Financial assets and liabilities at amortized cost***

The amounts of these financial instruments recognized in the statement of financial position do not significantly differ from fair value.

● **Cash and cash equivalents** - The carrying amounts informed in the financial position are identical to fair value because their yield rates are based on the changes in CDI rate (interbank deposit rate).

● **Trade and other receivables** - These arise directly from the operations of the Group, being measured at amortized cost and recorded at the original amount, net of a provision for losses, when applicable. The carrying amount approximates fair value, considering the extremely short settlement term of these transactions.

● **Loans and borrowing, trade payable, lease liabilities and other liabilities** - These are classified as financial liabilities measured at amortized cost in accordance with the contractual conditions.

***Financial instruments measured at fair value***

*Valuation techniques*

The table below presents the valuation techniques used to measure Level 2 fair values for financial instruments in the financial position:

---

| | |
|:---|:---|
| **Type** | **Valuation technique** |
| Derivative financial instruments | The fair value is calculated based on the present value of the estimated future cash flows. Estimates of future cash flows are based on quoted rates of swap. Estimated cash flows are discounted using a curve prepared based on similar sources and reflecting the relevant rate used by market participants for this purpose when pricing swaps. The fair value estimate is subject to a credit risk adjustment, calculated based on current prices of traded securities. |

---

&nbsp;&nbsp;&nbsp;&nbsp;**c.** **Risk management** 

The Group is exposed to the following risks resulting from financial instruments:

● Credit risk;

● Liquidity risk; and

● Market risk.

&nbsp;&nbsp;&nbsp;&nbsp;***(i)***  ***Risk management framework*** 

The Group's Financial Executive Board has full responsibility for the establishment and supervision of risk management structure.

The risk management policies of the Group are established to identify and analyze risks to which the Group is exposed, to set risk limits and appropriate controls, and to monitor risks and compliance with defined limits. Risk management policies and systems are reviewed regularly to reflect changes in the market conditions and in the Group's activities.

*Capital management* 

The policy of the Executive Board is to maintain a solid capital base to maintain the confidence of investor, creditor and market and the future development of the business. Executive Board also monitors the return of capital and also the level of dividends for shareholders.

The Group monitors capital based on the ratio of financial leverage. That index corresponds to the ratio divided between net debt and total capital.

Net debt, on its turn, corresponds to short and long-term loans and borrowing, derivative financial instruments and lease liabilities, less the amount of cash and cash equivalents. The total capital is calculated through the sum of shareholders' equity, as shown in the financial position, with net debt.

*Credit risk*

Credit risk is the risk of the Group incurring financial losses due to a client or financial instrument counterparty, resulting from failure in complying with contract obligations. Such risk is mainly due to trade accounts receivables.

------

The carrying amount amounts of financial assets represent the maximum credit exposure.

*Trade accounts receivables*

The Group's exposure to credit risks is influenced mainly by the individual characteristics of each client. However, management also considers the factors that may influence the credit risk of its client base, including the risk of non-payment of the industry and of the country in which the client operates.

The Financial Executive Board established a credit policy in which new client are analyzed individually to verify their financial status before the Group submits a credit limit proposal and payment terms.

The review carried out by the Management includes external ratings, when available, consolidated financial statements, credit agency information, industry information and in some cases, bank references. Credit limits are established for each client and are regularly reviewed.

The Group limits exposure to credit risk of accounts receivable, establishing a maximum payment period of 180 days.

The maximum exposure to credit risk for 'Accounts receivable' as well as by aging, is shown in Note 10.

At December 31, 2024, the exposure to credit risk for trade receivables by geographic region was as follows:

---

| | |
|:---|:---|
|  | **2024** |
| Brazil | 29,588 |
| Americas ex-Brazil | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;19,228 |
|  | **48,816** |

---

At December 31 2024, the carrying amount of the receivable from the Group's most significant customer was R$11,347.

*Expected credit loss*

The Group uses individual analysis to measure impairment loss on trade receivable.

The provision is calculated based on the individual assessment of each type of client contract, aging of the overdue balance and the actual experience of credit losses in the last 12 months, including quantitative and qualitative information and analysis, based on the Group's historical experience, credit assessment and considering prospective information.

Impairment losses on financial assets recognized in the year were disclosed in Note 10.

------

*Debt securities*

The policy of the Group for investments in debt securities (interest in earning bank deposits) is to invest in securities that have ratings attributed by the main credit risk agencies. Also, the Group monitors the amounts deposited and the concentration in certain institutions; thus, mitigates the financial loss in case of possible bankruptcy of a counterparty.

*Cash and cash equivalents*

The Group considers that its cash and cash equivalents have low credit risk based on foreign credit rating of counterparties.

*Derivative financial instruments*

Derivatives are contracted from banks and financial institutions that have market solidity.

*Guarantees*

There are no guarantees issued by the Group.

*Liquidity risk*

Liquidity risk is the risk that The Group may encounter difficulties in meeting its obligations associated with its financial liabilities as they fall due, whether settled in cash or with another financial asset.

The Group's approach to liquidity risk management is to ensure, as far as possible, that it always maintains sufficient liquidity to meet its obligations when due, under both normal and stressed conditions, without incurring unacceptable losses or risking damage to the Group's reputation. This is achieved through ongoing monitoring of cash flows, maintaining adequate levels of cash and cash equivalents, and access to committed credit facilities aligned with the Group's operational and financial needs.

The Group aims to maintain the level of its cash and cash equivalents and other highly marketable debt investments at an amount in excess of expected cash outflows on financial liabilities (other than trade payables).

*Exposure to liquidity risk*

The following are the remaining contractual maturities of financial liabilities at the reporting date. The amounts are gross and undiscounted and include contract interest payments and exclude the impact of netting agreements.

| | | | | |
|:---|:---|:---|:---|:---|
|  |  | **Contractual cash flows** | **Contractual cash flows** | **Contractual cash flows** |
|  | **Carrying amount** | **> 1 year** | **1**–**2 years** | **> 2 years** |
| Loans and borrowings | 83,951 | 22,918 | 13,430 | 56,335 |
| Trade and other accounts payables | 23,218 | 22,308 | 910 | - |
| Lease liabilities | 4,919 | 3,432 | 3,150 | - |

---

*Market risk*

Market risk is the risk that changes in market prices, such as foreign exchange rates and interest rates, will affect the Group's earnings or the value of its financial instruments.

------

The objective of market risk management is to manage and control market risk exposures within acceptable parameters, while optimizing returns. The Group monitors its exposure to market risks on an ongoing basis and adopts strategies consistent with its risk management policies.

The Group enters into derivative transactions and other financial arrangements to manage market risks, primarily related to foreign exchange and interest rate exposures.

*Currency risk*

The Group is exposed to transactional foreign currency risk to the extent that there is a mismatch between the currencies in which sales, purchases, receivables and borrowings are denominated and the respective functional currencies of Group companies. The functional currencies of Group companies are Brazilian Reais (R$). The foreign currency in which these transactions are primarily denominated is USD.

The Group uses derivative financial instruments, primarily swap, to hedge its foreign currency exposure regarding loans in foreign currency. Most of these contracts have maturities of less than one year from the reporting date and, when necessary, are rolled over at maturity to maintain the desired level of protection.

Interest in borrowings is denominated in the currency of the respective loans. In general, borrowings are contracted in currencies that are aligned with the currencies of the cash flows generated by the Group's core operations, mainly Brazilian reais, but also US dollars.

With respect to other monetary assets and liabilities denominated in foreign currencies, the Group seeks to ensure that its net exposure is maintained at an acceptable level by purchasing or selling foreign currencies at spot rates, when necessary, to manage short-term volatility.

*Exposure to currency risk*

The summary of quantitative data about the Group's exposure to currency risk is as follows.

---

| | | |
|:---|:---|:---|
|  | **2024** | **2024** |
| ***In thousand of R$*** | **USD** | **EUR** |
| Banks | 23304 |  |
| Trade receivables | 19228 |  |
| Trade payables | (8772) |  |
| Loans | (18620) | (54389) |
| **Net financial position exposure** | 15140 | (54389) |
| Swap contracts 25.d (notional) |  | 54389 |
| **Net exposure** | 15140 |  |
| **Year-end spot rate** | 6.1923 | 6.4363 |

---

*Sensitivity analysis*

The chart below states the sensitivity of assets and liabilities in foreign currency and their impact on the Group's income in a scenario where the quote changes up to 25%, up or down the official quote on December 31, 2024 (PTAX).

A reasonably possible appreciation (devaluation) of US dollar in relation to the Reais on December 31, 2024 would have affected measurement of financial instruments denominated in foreign currency and affected shareholders' equity and income at amounts stated below:

The analysis considers that all the remaining variables, especially interest rates, will remain constant and any impact on forecasted sales and purchases will be ignored. In addition, the analysis did not consider the loan transactions, as these exposures are fully covered by the swap agreement contracted concurrently, resulting in no residual risk to be assessed separately.

---

| | |
|:---|:---|
|  | **2024** |
| ***In thousand of R$*** | **USD** |
| *Net exposure* | 15140 |
| *Income impact, net of tax* |  |
| Scenario I – Variance of +25% | 2498 |
| Scenario II – Variance of -25% | (2498) |

---

*Interest rate risk*

The Group believes it is not significantly exposed to interest rate risk. This assessment reflects the fact that the Group maintains a similar level of financial investments and borrowings indexed to floating interest rates, substantially linked to the CDI (Brazilian interbank deposit rate). Because both interest-bearing assets and liabilities are subject to the same post-fixed rate dynamics, movements in the CDI are expected to have an offsetting effect on finance income and finance costs. As a result, potential fluctuations in interest rates are not expected to generate material impacts on the Group's profit or loss or on the carrying amounts of its financial instruments.

&nbsp;&nbsp;&nbsp;&nbsp;**d.** **Derivative financial instruments** 

The amounts classified as derivative financial instruments refer to the fair value of swap transactions to hedge exposures in EUR.

As of December 31, 2024 the Group conducted operations with swap instruments, which constitute agreements with financial institutions to exchange cash flows based on predetermined rates on a future settlement date. There is no cash disbursement at inception, and upon maturity the settlement is performed based on the difference between the contracted rate and the effective settlement rate. The main purpose of these transactions is to protect future net income and cash flows arising from exposures to foreign-currency-denominated loans.

During the year, The Group entered into a swap agreement linked to a EUR-denominated loan with the objective of converting its exposure from EUR to Brazilian reais at a predetermined fixed rate. Through this structure, The Group economically transforms the original foreign-currency obligation into a fixed-rate BRL liability, thereby mitigating the effects of exchange rate volatility on its financial statements and enhancing predictability of future cash flows.

The fair values were estimated based on available market information and specific valuation methodologies, discounted to present value. (Methodology described above in item (b)).

------

The notional amount and contractual maturities of the swap are aligned with the EUR-denominated loan of R$54,389 thousand disclosed in Note 17, while the fair value amount of R$669 is recorded in the statement of financial position.

On December 5, 2025, the controlling interest of Comtrafo Indústria de Transformadores Elétricos S.A. ("Comtrafo") was acquired by AMSC (American Superconductor Corporation), through a transaction that resulted in a change in the Comtrafo's ownership structure.

This transaction did not involve the subsidiary Eletrotrafo Produtos Elétricos Ltda. ("Eletrotrafo") which was distributed to the previous shareholders via a spin off on December 5, 2025. The summary statement of financial position of Eletrotrafo as of December 31, 2024 included in the consolidated financial statements of Comtrafo before consolidation adjustments was as follows:

---

| | |
|:---|:---|
| Cash and cash equivalents | 19312 |
| Trade and other receivables | 9125 |

| **Total shareholders' equity** | **46457** |

---

Additionally, as part of this transaction, the related-party lease agreements for the sites housing the Group's manufacturing facilities, described in Note 20, were terminated in 2025, as these properties were also acquired by AMSC and subsequently merged into Comtrafo's property, plant and equipment.

As part of the changes in the shareholder structure, in December 2025 the Group's share capital was increased by R$366,085, as follows: (i) in cash for acquisition to property, plant and equipment in the amount of R$168,941, and (ii) R$197,143 from the utilization of reserves.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Note 19 - recognition of provisions for contingencies: determining if there is a present obligation with probable likelihood of outflow of resources to settle the obligations.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**b)** **Assumptions and estimation uncertainties** 

Information about assumptions and estimation uncertainties as of September 30, 2025, that have a significant risk of resulting in a material adjustment to the carrying amounts of assets and liabilities within the next financial year is included in the following notes:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Note 18 – Recognition of deferred tax assets: availability of future taxable profits against which deductible temporary differences and tax losses carried forward can be utilized.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Note 10 – Key assumptions in determining the measurement of the impairment loss on trade receivables; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Note 19 - measurement of provisions for contingencies: main assumptions regarding the magnitude of the outflows of funds.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**c)** **Measurement of fair values** 

A number of the Group's accounting policies and disclosures require the measurement of fair value for both financial and non-financial assets and liabilities.

The Group established a control structure related to measurement of fair value.

When measuring fair value of an asset or liability, the Group uses observable data as much as possible. Fair values are classified at different levels according to hierarchy based on information (inputs) used in valuation techniques, as follows:

**Level 1:** Quoted prices (unadjusted) in active markets for identical assets or liabilities.

**Level 2:** Inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly (prices) or indirectly (derived from prices).

**Level 3:** Inputs for the asset or liability that are not based on observable market data (unobservable inputs).

The Group recognizes transfers between levels of the fair value hierarchy at the end of the reporting period in which the changes occur.

---

| | |
|:---|:---|
| **6** | **Basis of measurement** |

---

The unaudited consolidated interim financial statements have been prepared on the historical cost basis, except for derivative financial instruments, which are measured at fair value at each reporting date and changes in fair value are recognized in the statement of profit or loss.

---

| | |
|:---|:---|
| **7** | **Material accounting policies** |

---

The material accounting policies applied in these unaudited consolidated interim financial statements are described below:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**a.** **Basis of consolidation** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;***(i)***  ***Subsidiaries*** 

The Group controls an entity when it is exposed to, or has rights to, variable returns from its involvement with the entity and has the ability to affect those returns through its power over the entity. The financial statements of subsidiaries are included in the financial statements from the date on which the Group obtains control, until the date on which control ceases.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;***(ii)***  ***Transactions eliminated on consolidation*** 

Intra-group balances and transactions, and any unrealized income or expenses arising from intra-Group transactions, are eliminated.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;***(iii)***  ***Non-controlling interests account policy*** 

Changes in the Group's ownership interest in a subsidiary that do not result in a loss of control are accounted for as equity transactions.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**b.** **Foreign currency** 

&nbsp;&nbsp;&nbsp;&nbsp;***(i) Foreign currency transactions***

Foreign currency transactions are translated into Brazilian reais, which is the functional currency of the Group, at the exchange rates prevailing at the dates of the transactions.

Monetary assets and liabilities denominated in foreign currencies at the reporting date are retranslated into the functional currency at the exchange rates at the reporting date. Non-monetary items that are measured based on historical cost in a foreign currency are translated using the exchange rates at the dates of the transactions. Foreign exchange differences arising on translation are generally recognized in profit or loss

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**c.** **Revenue** 

The Group's revenue is generated primarily from three operating activities: (i) the sale of power transformers and related components in both domestic and international markets; (ii) the resale of electrical materials through retail operations; and (iii) the provision of electrical installation services. See Note 22 for detailed information on performance obligations and revenue recognition.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**d.** **Short-term employee benefits** 

Short-term employee benefit obligations are recognized as personnel expenses as the related services are rendered. A liability is recognized for the amount expected to be paid if the Group has a present legal or constructive obligation to pay this amount as a result of past service provided by employees and the obligation can be reliably estimated.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**e.** **Finance income and finance expenses** 

The Group finance income and finance expenses comprise:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Interest income;<br> • Interest expense;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Foreign exchange gains and losses on financial assets and liabilities; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Gains and losses on derivatives instruments transactions.

Interest income and interest expense are recognized in profit or loss using the effective interest method.

The 'effective interest rate' is the rate that estimated future cash payments or receipts through the expected life of the financial instrument to:

● the gross carrying amount of the financial asset; or

● the amortized cost of the financial liability.

In calculating interest income and expense, the effective interest rate is applied to the gross carrying amount of the financial asset (when the asset is not credit-impaired) or to the amortized cost of the liability. However, for financial assets that have become credit-impaired subsequent to initial recognition, interest income is calculated by applying the effective interest rate to the amortized cost of the financial asset. If the asset is no longer credit-impaired, then the calculation of interest income reverts to the gross basis.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**f.** **Income tax and social contribution** 

Current and deferred income tax and social contribution are calculated based on the statutory tax rates of 15%, plus a 10% surplus on taxable profit exceeding R$240 (annual basis) for income tax purposes, and 9% on taxable profit for social contribution on net income, taking into account the offset of tax losses and negative tax bases for social contribution, limited to 30% of the taxable profit for the year.

Income tax and social contribution expense comprises current and deferred income tax and social contribution. Current and deferred taxes are recognized in profit or loss unless they relate to a business combination or to items recognized directly in equity or in other comprehensive income.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;***(i)***  ***Current tax*** 

Current tax expense represents the estimated tax payable or recoverable on the taxable profit or loss for the year, including any adjustments to tax payable in respect of prior years. The amount of current tax payable or recoverable is recognized in the statement of financial position as a tax asset or liability based on the best estimate of the amount expected to be paid to or recovered from the tax authorities, reflecting any uncertainties related to its determination, if applicable. Current tax is measured using tax rates enacted or substantively enacted at the reporting date.

Current tax assets and liabilities are offset only when certain criteria are met.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;***(ii)***  ***Deferred tax*** 

Deferred tax assets and liabilities are recognized for temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and their corresponding tax basis. Changes in deferred tax assets and liabilities during the year are recognized as deferred income tax and social contribution expense.

Deferred tax assets are recognized in respect of deductible temporary differences and unused tax losses to the extent that it is probable that future taxable profits will be available against which they can be utilized. Deferred tax assets are reviewed at each reporting date and are reduced to the extent that it is no longer probable that the related tax benefit will be realized. Deferred tax assets and liabilities are measured using the tax rates expected to apply to the temporary differences when they reverse, based on tax rates that have been enacted or substantively enacted by the reporting date.

The measurement of deferred tax assets and liabilities reflects the tax consequences that would follow from the manner in which the Group expects, at the reporting date, to recover or settle the carrying amount of its assets and liabilities.

Deferred tax assets and liabilities are offset only when certain criteria are met.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**g.** **Inventories** 

Inventories are measured at the lower of cost and net realizable value. The cost of inventories is based on the weighted average cost method and includes expenditures incurred in the acquisition of inventories, production and conversion costs, and other costs incurred in bringing inventories to their present location and condition. In the case of work in progress inventories, cost includes an allocation of manufacturing overheads based on normal operating capacity.

The net realizable value is the estimated selling price in the ordinary course of business, less the estimated costs of completion and the estimated costs necessary to make the sale.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**h.** **Property, plant and equipment** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;***(i)***  ***Recognition and measurement*** 

Items of property, plant and equipment are measured at historical cost of acquisition or construction, less accumulated depreciation and any accumulated impairment losses (if any).

When significant parts of an item of property, plant and equipment have different useful lives, they are accounted for as separate items (major components) of property, plant and equipment.

Any gains or losses arising from the disposal of an item of property, plant and equipment are recognized in profit or loss.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;***(ii)***  ***Subsequent expenditure*** 

Subsequent expenditures are capitalized only when it is probable that future economic benefits associated with the expenditure will flow to the Group and the cost can be measured reliably. All other subsequent expenditure is recognized in profit or loss as incurred.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;***(iii)***  ***Depreciation*** 

Depreciation is calculated to write off the cost of items of property, plant and equipment, net of their estimated residual values, on a straight-line basis over their estimated useful lives. Depreciation is recognized in profit or loss. Land is not depreciated.

The estimated useful lives of property, plant and equipment are as follows:

---

| | |
|:---|:---|
|  | **Years of** <br> **useful lives** |
| &nbsp;&nbsp;&nbsp; Vehicles | 04 years |
| &nbsp;&nbsp;&nbsp; Commercial Installations | 10 years |
| &nbsp;&nbsp;&nbsp; Machinery and equipment | 10 years |
| &nbsp;&nbsp;&nbsp; Furniture and fixtures | 10 years |
| &nbsp;&nbsp;&nbsp; IT equipment | 6 – 7 years |
| &nbsp;&nbsp;&nbsp; Communication equipment | 6 – 7 years |
| &nbsp;&nbsp;&nbsp; Tools and accessories | 10 years |

---

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**i.** **Financial instruments** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;***(i)***  ***Initial recognition and measurement*** 

Financial assets and financial liabilities are initially recognized when the Group becomes a party to the contractual provisions of the instrument.

A financial asset (unless it is a trade receivable without a significant financing component) or financial liability is initially measured at fair value plus or minus, for items not measured at fair value through profit or loss (FVTPL), transaction costs that are directly attributable to its acquisition or issuance. Trade receivables without a significant financing component are initially measured at the transaction price.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;***(ii)***  ***Classification and subsequent measurement*** 

***Financial assets - classification***

On initial recognition, a financial asset is classified as subsequently measured at: amortized cost or FVTPL.

Financial assets are not subsequently reclassified after initial recognition unless the Group changes its business model for managing financial assets. In such case, all affected financial assets are reclassified on the first day of the reporting period following the change in the business model.

A financial asset is measured at amortized cost if it meets both of the following conditions and is not designated as measured at fair value through profit or loss (FVTPL):

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• it is held within a business model whose objective is to hold financial assets in order to collect contractual cash flows; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• its contractual terms give rise, on specified dates, to cash flows that are solely payments of principal and interest (SPPI) on the principal amount outstanding.

All financial assets, except for derivative financial instruments which are measured at FVTPL, are measured at amortized cost.

***Financial assets*** – ***Business model assessment***

The Group maintains a single business model for all of its financial assets, which is solely to hold such assets in order to collect the related contractual cash flows. Under this business model, financial assets are managed with the objective of collecting contractual cash flows over the life of the instrument, and not for the purpose of selling them. Accordingly, all financial assets are evaluated for classification and measurement based on the Group's intention and ability to hold these assets to collect contractual cash flows that are solely payments of principal and interest ("SPPI").

***Financial assets*** – ***subsequent measurement and gains and losses***

| &nbsp;&nbsp;&nbsp; Financial assets at FVTPL | These assets are subsequently measured at fair value. Net gains and losses, including any interest are recognized in profit or loss. |

---

*Financial liabilities* – *classification, subsequent measurement and gains and losses*

Financial liabilities are classified and measured as amortized cost, except for derivative financial instruments, which are measured at fair value at each reporting date and changes in fair value are recognized in the statement of profit or loss.

Financial liabilities (other than derivative financial instruments) are subsequently measured at amortized cost using the effective interest method. Interest expense, foreign exchange gains and losses are recognized in statement of profit or loss. Any gain or loss on derecognition is also recognized in statements of profit or loss.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;***(iii)***  ***Derecognition*** 

*Financial assets*

The Group derecognizes a financial asset when the contractual rights to the cash flow of the asset expire, or when the Group transfers the rights to receive the contractual cash flows over a financial asset in a transaction in which essentially all the risks and rewards of ownership of the financial asset are transferred or in which the Group neither transfers or maintains all ownership risks and rewards of the financial assets and also does not hold the control over the financial asset.

*Financial liabilities*

The Group derecognizes a financial liability when its contractual obligation is discharged, cancelled or expires. A financial liability is also derecognized when its terms are modified and the cash flows of the modified liability are substantially different, in which case a new financial liability based on the modified terms is recognized at fair value.

On derecognition of a financial liability, the difference between the carrying amount extinguished and the consideration paid (including non-cash assets transferred or liabilities assumed) is recognized in profit or loss.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;***(iv)***  ***Offseting*** 

Financial assets and financial liabilities are offset and the net amount is presented in the statement of financial position when, and only when, the Group currently has a legally enforceable right to set off the recognized amounts and intends either to settle on a net basis or to realize the asset and settle the liability simultaneously.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;***(v)***  ***Derivative financial instruments*** 

The Group holds derivative financial instruments to hedge its exposure to risks of foreign currency changes.

Derivatives are initially measured at fair value. After the initial recognition, derivatives are measured at fair value and changes are recorded in statement of profit or loss.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**j.** **Impairment** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;***(i)***  ***Non-derivative financial assets*** 

*Financial instruments*

The Group recognizes Impairment loss on trade accounts receivables for expected credit losses on:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;● Financial assets measured at amortized cost (trade and other receivables).

The Group measures impairment loss on trade receivables at an amount equal to expected credit losses for life, except for items described below, which are measured as expected credit loss for 12 months: and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;● Other debt securities and bank balances for which the credit risk (i.e., default risk throughout the expected life of financial instruments) has not significantly increased since the beginning of initial recognition.

Impairment loss on trade accounts receivables is measured at a value equal to an expected credit loss for the instrument's entire life.

When determining if the credit risk of a financial asset has significantly increased since the initial recognition and when estimating expected credit losses, the Group considers reasonable and tolerable information that is relevant and available without excessive cost or effort. This includes quantitative and qualitative information and analysis, based on the Group's historical experience, credit assessment, and considering prospective information (forward-looking).

The Group assumes that the credit risk in a financial asset increased significantly if it is more than 90 days overdue.

The Group considers a financial asset in default when:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;● It is highly unlikely that the debtor will fully meet its credit obligations to the Group without the Group needing to enforce collateral or take similar recovery actions.; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;● Financial assets are past due for more than 360 days.

*Measurement of impairment losses*

Impairment losses are estimates weighted by likelihood of credit loss. Credit losses are measured at present value based on all cash insufficiencies (that is, the difference between the cash flows owed to the Group in accordance with the contract and the cash flows that the Group expects to receive).

***Financial assets with recovery issues***

On each reporting date, the Group evaluates whether the financial assets accounted for at amortized cost are experiencing recovery problems. A financial asset has "recovery problems" when one or more events with a negative impact on the estimated future cash flows of the financial asset occur.

Objective evidence that financial assets had recovery problems includes the following observable data:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;● Significant financial difficulties of the customer;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;● Breach of contractual clauses, such as delinquency or late payment of more than 360 days;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;● Restructuring of an amount due to the Group under conditions that would not be accepted in normal conditions;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;● The probability that the borrower will enter bankruptcy or other financial reorganization; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;● The disappearance of an active market for that financial asset because of financial difficulties.

*Presentation of allowance for expected credit losses on financial position.*

Allowance for expected credit losses in financial assets measured at amortized cost are deducted from the gross carrying amount of the assets.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;***(ii)***  ***Non-financial assets*** 

At each reporting date, the Group reviews the carrying amounts of its non-financial assets (except for inventories and deferred tax assets) to determine whether there is any indication of impairment.

For impairment tests, assets are grouped into the cash generating units (CGUs), that is, smallest identifiable group of assets that can generate cash inflows by continuous use, which are highly independent from cash inflows referring to other assets or cash generating units.

Recoverable value of an asset or CGU is the higher of value in use and fair value less selling costs. Value in use is based on estimated future cash flows discounted to present value using a discount rate before taxes that reflects current market evaluations of times value of money and the specific risks of the assets or CGU.

An impairment loss is recognized when the carrying amount of an asset or its CGU exceeds its recoverable value.

Impairment losses are recognized in profit or loss.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**k.** **Provisions** 

Provisions are recognized when the Group has a present obligation, as a result of past events, and it is likely that an outflow of funds will be necessary to settle the obligation.

Provisions for lawsuits are recorded based on best estimates of risk involved and are established at amounts considered sufficient to cover probable losses. The lawsuits estimated as possible losses are disclosed in the notes and those estimated as remote losses are neither provisioned nor disclosed.

Tax, civil and labor contingencies subject to judicial disputes are reassessed periodically and accounted for based on management assessment, supported by opinions of legal counsel and regarding the probable outcome of the legal proceedings at the reporting dates.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**l.** **Leases** 

At inception of a contract, the Group determines whether a contract is, or contains, a lease.

A contract is, or contains, a lease if it conveys the right to control the use of an identified asset for a period of time in exchange for consideration.

**As a lessee**

At commencement or modification of a contract that contains a lease component, the Group allocates the consideration in the contract to each lease component based on their relative stand-alone prices. However, for leases of property, the Group has elected not to separate non-lease components and accounts for the lease and non-lease components as a single lease component.

The Group recognizes a right-of-use asset and a lease liability at the lease commencement date. The right-of-use asset is initially measured at cost, which comprises the initial measurement of the lease liability, adjusted for any lease payments made at or before the commencement date, plus any initial direct costs incurred by the lessee and an estimate of costs to be incurred by the lessee in dismantling and removing the underlying asset, restoring the site on which it is located or restoring the underlying asset to the condition required by the terms and conditions of the lease, less any lease incentives received.

The right-of-use asset is subsequently depreciated using the straight-line method from the commencement date to the earlier of the end of the lease term or the end of the useful life of the right-of-use asset, unless the lease transfers ownership of the underlying asset to the lessee by the end of the lease term or the cost of the right-of-use asset reflects that the lessee will exercise a purchase option. In such cases, the right-of-use asset is depreciated over the useful life of the underlying asset, which is determined on the same basis as for property, plant and equipment. In addition, the right-of-use asset is periodically reduced by impairment losses, if any, and adjusted for certain remeasurements of the lease liability.

The lease liability is initially measured at the present value of the lease payments that are not paid at the commencement date, discounted using the interest rate implicit in the lease or, if that rate cannot be readily determined, the Group's incremental borrowing rate. the Group generally uses its incremental borrowing rate as the discount rate.

The Group determines its incremental borrowing rate by obtaining interest rates from various external financing sources and making adjustments to reflect the terms of the lease contract and the type of the leased asset.

Lease payments included in the measurement of the lease liability comprise the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• fixed payments, including in-substance fixed payments;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• variable lease payments that depend on an index or a rate, initially measured using the index or rate as at the commencement date;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• amounts expected to be payable by the lessee under residual value guarantees; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the exercise price of a purchase option if the lessee is reasonably certain to exercise that option, and payments of penalties for terminating the lease, if the lease term reflects the lessee exercising an option to terminate the lease.

The lease liability is subsequently measured at amortized cost using the effective interest method. It is remeasured when there is a change in future lease payments resulting from a change in an index or a rate, when there is a change in the amounts expected to be payable under a residual value guarantee, when the Group changes its assessment of whether it will exercise a purchase, extension or termination option, or when there is a revised in-substance fixed lease payment.

When the lease liability is remeasured in this manner, a corresponding adjustment is made to the carrying amount of the right-of-use asset, or is recognized in profit or loss if the carrying amount of the right-of-use asset has been reduced to zero.

From January 1, 2021, to the extent that the basis for determining future lease payments changes as required by the interest rate benchmark reform, the Group remeasures the lease liability by discounting the revised lease payments using a revised discount rate that reflects the change to an alternative benchmark interest rate.

**Short-term leases and leases of low-value assets**

The Group has elected not to recognize right-of-use assets and lease liabilities for leases of low-value assets and short-term leases, including IT equipment. The Group recognizes the lease payments associated with these leases as an expense on a straight-line basis over the lease term.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**m.** **Fair value measurement** 

'Fair value' is the price that would be received to sell an asset or paid for the transfer of a liability in an orderly transaction between market participants at the measurement date, on the primary market or, in the absence thereof, on the most advantageous market to which the Group has access on such date. The fair value of a liability reflects its risk of default (non-performance).

A number of the Group's accounting policies and disclosures require the measurement of fair

values, for both financial and non-financial assets and liabilities.

When one is available, the Group measures the fair value of an instrument using the price quoted in an active market for that instrument. A market is regarded as 'active' if the transactions for the asset or liability take place with sufficient frequency and volume to provide pricing information on an ongoing basis.

If there is no quoted price in an active market, then the Group uses valuation techniques that maximise the use of relevant observable inputs and minimize the use of unobservable inputs. The chosen valuation technique incorporates all of the factors that market participants would take into account in pricing a transaction.

If an asset or a liability measured at fair value has a purchase and a selling price, the Group measures the assets based on purchase prices and liabilities based on selling prices. The chosen valuation technique incorporates all the factors market participants would take into account when pricing a transaction.

The best evidence of fair value of a financial instrument at initial recognition is normally the transaction price – i.e. the fair value of the consideration given or received. If the Group determines that fair value at initial recognition differs from transaction price and fair value is not evidenced, not even by price quoted in an active market for an identical asset or liability, neither based on valuation technique for which non-observable data is judged as insignificant for measurement, then financial instrument is initially measured at adjusted fair value, to distinguish the difference between fair value at initial recognition and transaction price. This difference is subsequently recognized in statement of profit or loss on an appropriate basis over the life of the instrument, or until such time when its valuation is fully supported by observable market data or the transaction is closed, whichever comes first.

| **8** | **Accounting standards issued but not yet effective** |

---

A number of new accounting standards are effective for annual reporting periods beginning after 1 January 2025, but earlier application was not permitted. Therefore, the Group has not early adopted the following new or amended accounting standards in the preparation of these consolidated financial statements

**IFRS 18 Presentation and Disclosure in Consolidated financial statements**

IFRS 18 will replace IAS 1 Presentation of financial statements and applies for annual reporting periods beginning on or after 1 January 2027. The new accounting standard introduces the following key new requirements.

Entities are required to classify all income and expenses into five categories in the statement of profit or loss, namely the operating, investing, financing, discontinued operations and income tax categories. Entities are also required to present a newly-defined operating profit subtotal. Entities' net profit will not change.

Management-defined performance measures (MPMs) are disclosed in a single note in the consolidated financial statements.

Enhanced guidance is provided on how to group information in the consolidated financial statements.

In addition, all entities are required to use the operating profit subtotal as the starting point for the statement of cash flows when presenting operating cash flows under the indirect method.

The Group is still in the process of assessing the impact of the new accounting standard, particularly with respect to the structure of the Group's statement of profit or loss, the statement of cash flows and the additional disclosures required for MPMs. The Group is also assessing the impact on how information is grouped in the consolidated financial statements, including for items currently labelled as 'other'.

**Other accounting standards**

The following new and amended accounting standards are not expected to have a significant impact on the Group's consolidated financial statements:

*Classification and Measurement of Financial Instruments (Amendments to IFRS 9 and IFRS 7); and*

*Contracts Referencing Nature*-*dependent Electricity (Amendments to IFRS 9 and IFRS 7).*

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Classification and Measurement of Financial Instruments – Amendments to IFRS 9 and IFRS 7, effective for annual reporting periods beginning on January 1, 2026;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Contracts Referencing Nature-dependent Electricity – Amendments to IFRS 9 and IFRS 7;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Annual Improvements to IFRS Accounting Standards – Volume 11;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• IFRS 19 Subsidiaries without Public Accountability: Disclosures; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Sale or Contribution of Assets between an Investor and its Associate or Joint Venture – Amendments to IFRS 10 and IAS 28, with an effective date to be determined.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) The Group benefits from state tax incentives related to ICMS (State VAT), which are classified as subventions for investment pursuant to Complementary Law No. 160/2017. This legislation established that incentives and tax benefits granted by the Brazilian states, including presumed ICMS credits and other fiscal-financial mechanisms, qualify as investment subsidies when intended to support the implementation or expansion of economic activities. As permitted by LC 160/2017, the Group excludes from the income tax basis the amounts corresponding to these ICMS incentives, which are recorded in a specific equity reserve ("tax incentive reserve") and are not available for distribution to shareholders. The related tax effects are reflected in the Group's current and deferred income taxes, as applicable.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) The Group determines its current income tax expense based on quarterly taxable income. In the fourth quarter of 2024, the Group generated a taxable loss, which may only be utilized as a deduction against taxable profits in future periods. The Company utilized R$4,539 of tax loss carryforwards during the nine-month period ended September 30, 2025. Following this utilization, the deferred tax asset related to tax loss carryforwards totaled R$6,886 as of September 30, 2025.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) It relates to inventories written-off for which the tax deductibility will only occur by the end of the year, following administrative tax procedures.

Deferred tax assets and liabilities arising from temporary differences are recognized to the extent that it is probable that taxable profit will be available against which the deductible temporary differences can be utilized. The realization of these deferred tax balances will occur as the underlying temporary differences reverse in future periods, in accordance with the expected pattern of recovery or settlement of the related assets and liabilities.

The assessment of the recoverability of deferred tax assets is based on forecasts of taxable profits, which incorporate a number of financial and business assumptions as of the reporting date. Accordingly, these estimates are subject to uncertainty and may differ from actual results due to the inherent uncertainty associated with such projections.

Management reviews these assumptions on a periodic basis and, when necessary, adjusts the carrying amounts of deferred tax assets to reflect the expected level of realization.

The Group is involved in tax, labor and civil legal proceedings at various stages of litigation. Where applicable, these matters are supported by judicial deposits. Management, based on assessments performed with the support of external and internal legal advisors, recognizes provisions for those contingencies for which a present obligation exists and the risk of loss is considered probable.

The measurement of such provisions reflects the best estimate of the expenditure required to settle the present obligation at the reporting date, incorporating the uncertainties inherent in the outcome of these proceedings. Management also updates these estimates periodically to reflect new facts, legal developments, and the most current information available.

Below is presented the amount of provision for labor and other risks for the nine-month period ended September 30, 2025:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**b.** **Tax incentive reserves** 

Brazilian Law No. 11,638/2007 introduced Article 195-A into Law No. 6,404/1976, which allows entities to appropriate the portion of net profit arising from government grants for investment to a Tax Incentive Reserve.

In this context, an entity may, in each reporting period, transfer from profit for the year to the tax incentive reserve an amount corresponding to the government grant received, so that such amount is not distributed as profits or dividends to shareholders. The adoption of this procedure is essential to ensure that government grants for investment are not subject to income tax (IRPJ) and social contribution (CSLL).

Accordingly, as the amounts arising from government grants were properly recognized in profit or loss for the period and included in retained earnings,

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**c.** **Legal reserve** 

The legal reserve is appropriated at 5% of profit for the year, up to the maximum limit of 20% of paid-in share capital, and is intended to ensure the integrity of share capital. This reserve may only be used to increase share capital or to offset accumulated losses.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**d.** **Working capital reserve** 

The working capital reserve is constituted in accordance with Article 38, paragraph 23, of The Group's Bylaws and is intended to support investments in non-current assets and increases in working capital, including through the amortization of The Group's indebtedness.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**e.** **Profit retention reserve** 

In accordance with Articles 197 and 202 of Law No. 6,404/1976, Management proposes the appropriation of the remaining balance of accumulated profits to the profit retention reserve.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**b.** **Measurement of fair value** 

***Financial assets and liabilities at amortized cost***

The amounts of these financial instruments recognized in the statement of financial position do not significantly differ from fair value.

● **Cash and cash equivalents** - The carrying amounts informed in the financial position are identical to fair value because their yield rates are based on the changes in CDI rate (interbank deposit rate).

● **Trade and other receivables** - These arise directly from the operations of the Group, being measured at amortized cost and recorded at the original amount, net of a provision for losses, when applicable. The carrying amount approximates fair value, considering the extremely short settlement term of these transactions.

● **Loans and borrowing, trade payable, lease liabilities and other liabilities** - These are classified as financial liabilities measured at amortized cost in accordance with the contractual conditions.

***Financial instruments measured at fair value***

*Valuation techniques*

The table below presents the valuation techniques used to measure Level 2 fair values for financial instruments in the financial position:

---

| | |
|:---|:---|
| **Type** | **Valuation technique** |
| Derivative financial instruments | The fair value is calculated based on the present value of the estimated future cash flows. Estimates of future cash flows are based on quoted rates of swap. Estimated cash flows are discounted using a curve prepared based on similar sources and reflecting the relevant rate used by market participants for this purpose when pricing swaps. The fair value estimate is subject to a credit risk adjustment, calculated based on current prices of traded securities. |

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**c.** **Risk management** 

The Group is exposed to the following risks resulting from financial instruments:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;● Credit risk;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;● Liquidity risk; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;● Market risk.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;***(i) Risk management framework***

The Group's Financial Executive Board has full responsibility for the establishment and supervision of risk management structure.

The risk management policies of the Group are established to identify and analyze risks to which the Group is exposed, to set risk limits and appropriate controls, and to monitor risks and compliance with defined limits. Risk management policies and systems are reviewed regularly to reflect changes in the market conditions and in the Group's activities.

***Capital management***

The policy of the Executive Board is to maintain a solid capital base to maintain the confidence of investor, creditor and market and the future development of the business. Executive Board also monitors the return of capital and also the level of dividends for shareholders.

The Group monitors capital based on the ratio of financial leverage. That index corresponds to the ratio divided between net debt and total capital.

Net debt, on its turn, corresponds to short and long-term loans and borrowing, derivative financial instruments and lease liabilities, less the amount of cash and cash equivalents. The total capital is calculated through the sum of shareholders' equity, as shown in the financial position, with net debt.

*Credit risk*

Credit risk is the risk of the Group incurring financial losses due to a client or financial instrument counterparty, resulting from failure in complying with contract obligations. Such risk is mainly due to trade accounts receivables.

The carrying amount amounts of financial assets represent the maximum credit exposure.

*Trade accounts receivables*

The Group's exposure to credit risks is influenced mainly by the individual characteristics of each client. However, management also considers the factors that may influence the credit risk of its client base, including the risk of non-payment of the industry and of the country in which the client operates.

The Financial Executive Board established a credit policy in which new client are analyzed individually to verify their financial status before the Group submits a credit limit proposal and payment terms.

The review carried out by the Management includes external ratings, when available, consolidated financial statements, credit agency information, industry information and in some cases, bank references. Credit limits are established for each client and are regularly reviewed.

The Group limits exposure to credit risk of accounts receivable, establishing a maximum payment period of 180 days.

The maximum exposure to credit risk for 'Accounts receivable' as well as by aging, is shown in Note 10.

At September 30, 2025, the exposure to credit risk for trade receivables by geographic region was as follows:

---

| | |
|:---|:---|
|  | **September 30, 2025** |
| Brazil | 50,226 |
| Americas ex-Brazil | 3,440 |
|  | **53,666** |

---

At September 30 2025, the carrying amount of the receivable from the Group's most significant customer was R$9,815.

*Expected credit loss*

The Group uses individual analysis to measure impairment loss on trade receivable.

The provision is calculated based on the individual assessment of each type of client contract, aging of the overdue balance and the actual experience of credit losses in the last 12 months, including quantitative and qualitative information and analysis, based on the Group's historical experience, credit assessment and considering prospective information.

Impairment losses on financial assets recognized during the nine-month period ended September 30, 2025 were disclosed in Note 10.

*Debt securities*

The policy of the Group for investments in debt securities (interest in earning bank deposits) is to invest in securities that have ratings attributed by the main credit risk agencies. Also, the Group monitors the amounts deposited and the concentration in certain institutions; thus, mitigates the financial loss in case of possible bankruptcy of a counterparty.

*Cash and cash equivalents*

The Group considers that its cash and cash equivalents have low credit risk based on foreign credit rating of counterparties.

*Derivative financial instruments*

Derivatives are contracted from banks and financial institutions that have market solidity.

*Guarantees*

There are no guarantees issued by the Group.

***Liquidity risk***

Liquidity risk is the risk that The Group may encounter difficulties in meeting its obligations associated with its financial liabilities as they fall due, whether settled in cash or with another financial asset.

The Group's approach to liquidity risk management is to ensure, as far as possible, that it always maintains sufficient liquidity to meet its obligations when due, under both normal and stressed conditions, without incurring unacceptable losses or risking damage to the Group's reputation. This is achieved through ongoing monitoring of cash flows, maintaining adequate levels of cash and cash equivalents, and access to committed credit facilities aligned with the Group's operational and financial needs.

The Group aims to maintain the level of its cash and cash equivalents and other highly marketable debt investments at an amount in excess of expected cash outflows on financial liabilities (other than trade payables).

*Exposure to liquidity risk*

The following are the remaining contractual maturities of financial liabilities at the reporting date. The amounts are gross and undiscounted and include contract interest payments and exclude the impact of netting agreements.

---

| | | | | |
|:---|:---|:---|:---|:---|
|  |  | **Contractual cash flows** | **Contractual cash flows** | **Contractual cash flows** |
|  | **Carrying amount** | **> 1 year** | **1**–**2 years** | **> 2 years** |
| Loans and borrowings | 64,245 | 20,215 | 25,211 | 23,315 |
| Trade and other accounts payables | 30,195 | 28,749 | 1,447 | - |
| Lease liabilities | 5,346 | 4,112 | 1,681 | - |

---

***Market risk***

Market risk is the risk that changes in market prices, such as foreign exchange rates and interest rates, will affect the Group's earnings or the value of its financial instruments.

The objective of market risk management is to manage and control market risk exposures within acceptable parameters, while optimizing returns. The Group monitors its exposure to market risks on an ongoing basis and adopts strategies consistent with its risk management policies.

The Group enters into derivative transactions and other financial arrangements to manage market risks, primarily related to foreign exchange and interest rate exposures.

***Currency risk***

The Group is exposed to transactional foreign currency risk to the extent that there is a mismatch between the currencies in which sales, purchases, receivables and borrowings are denominated and the respective functional currencies of Group companies. The functional currencies of Group companies are Brazilian Reais (R$). The foreign currency in which these transactions are primarily denominated is USD.

The Group uses derivative financial instruments, primarily swap, to hedge its foreign currency exposure regarding loans in foreign currency. Most of these contracts have maturities of less than one year from the reporting date and, when necessary, are rolled over at maturity to maintain the desired level of protection.

Interest in borrowings is denominated in the currency of the respective loans. In general, borrowings are contracted in currencies that are aligned with the currencies of the cash flows generated by the Group's core operations, mainly Brazilian reais, but also US dollars.

With respect to other monetary assets and liabilities denominated in foreign currencies, the Group seeks to ensure that its net exposure is maintained at an acceptable level by purchasing or selling foreign currencies at spot rates, when necessary, to manage short-term volatility.

*Exposure to currency risk*

The summary of quantitative data about the Group's exposure to currency risk is as follows.

---

| | | |
|:---|:---|:---|
|  | **September 30, 2025** | **September 30, 2025** |
| ***<u>In thousand of R$</u>*** | **USD** | **EUR** |
| Banks | 50909 | **-** |
| Trade receivables | 3440 | **-** |
| Trade payables | (4446) | **-** |
| Loans | (15995) | (35494) |
| **Net financial position exposure** | 33908 | (35494) |
| Swap contracts 25.d (notional) | - | 35494 |
| **Net exposure** | 33908 | **-** |
| **Period-end spot rate** | 5.3186 | 6.2414 |

---

*Sensitivity analysis*

The chart below states the sensitivity of assets and liabilities in foreign currency and their impact on the Group's income in a scenario where the quote changes up to 25%, up or down the official quote on September 30, 2025 (PTAX).

A reasonably possible appreciation (devaluation) of US dollar in relation to the Reais on September 30, 2025 would have affected measurement of financial instruments denominated in foreign currency and affected shareholders' equity and income at amounts stated below:

The analysis considers that all the remaining variables, especially interest rates, will remain constant and any impact on forecasted sales and purchases will be ignored. In addition, the analysis did not consider the loan transactions, as these exposures are fully covered by the swap agreement contracted concurrently, resulting in no residual risk to be assessed separately.

---

| | |
|:---|:---|
| | **2025** |
| <br>***<u>In thousand of R$</u>*** | **USD** |
| *Net exposure* | 33908 |
| *Income impact, net of tax* |  |
| Scenario I – Variance of +25% | 5595 |
| Scenario II – Variance of -25% | (5595) |

---

***Interest rate risk***

The Group believes it is not significantly exposed to interest rate risk. This assessment reflects the fact that the Group maintains a similar level of financial investments and borrowings indexed to floating interest rates, substantially linked to the CDI (Brazilian interbank deposit rate). Because both interest-bearing assets and liabilities are subject to the same post-fixed rate dynamics, movements in the CDI are expected to have an offsetting effect on finance income and finance costs. As a result, potential fluctuations in interest rates are not expected to generate material impacts on the Group's profit or loss or on the carrying amounts of its financial instruments.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**d.** **Derivative financial instruments** 

The amounts classified as derivative financial instruments refer to the fair value of swap transactions to hedge exposures in EUR.

As of September 30, 2025 the Group conducted operations with swap instruments, which constitute agreements with financial institutions to exchange cash flows based on predetermined rates on a future settlement date. There is no cash disbursement at inception, and upon maturity the settlement is performed based on the difference between the contracted rate and the effective settlement rate. The main purpose of these transactions is to protect future net income and cash flows arising from exposures to foreign-currency-denominated loans.

During the period, The Group entered into a swap agreement linked to a EUR-denominated loan with the objective of converting its exposure from EUR to Brazilian reais at a predetermined fixed rate. Through this structure, The Group economically transforms the original foreign-currency obligation into a fixed-rate BRL liability, thereby mitigating the effects of exchange rate volatility on its financial statements and enhancing predictability of future cash flows.

The fair values were estimated based on available market information and specific valuation methodologies, discounted to present value. (methodology described above in item (b)).

The notional amount and contractual maturities of the swap are aligned with the EUR-denominated loan of R$35,494 thousand disclosed in Note 17, while the fair value amount of R$3,511 is recorded in the statement of financial position.

On December 5, 2025, the controlling interest of Comtrafo Indústria de Transformadores Elétricos S.A. ("Comtrafo") was acquired by AMSC (American Superconductor Corporation), through a transaction that resulted in a change in the Comtrafo's ownership structure.

This transaction did not involve the subsidiary Eletrotrafo Produtos Elétricos Ltda. ("Eletrotrafo") which was distributed to the previous shareholders via a spin off on December 5, 2025. The summary statement of financial position of Eletrotrafo as of September 30, 2025, included in the unaudited consolidated interim financial statements of Comtrafo before consolidation adjustments was as follows:

## Exhibit 99.3

**Exhibit 99.3**

**UNAUDITED PRO FORMA COMBINED FINANCIAL INFORMATION**

On December 5, 2025 (the "Closing Date"), Mardin Participações Ltda., an entity incorporated in Brazil ("AMSC Brazil") and a wholly-owned subsidiary of American Superconductor Corporation, a Delaware corporation (the "Company"), entered into a Stock Exchange Agreement (the "Stock Exchange Agreement") with each of the sellers listed on the signature pages thereto (each, a "Stockholder" and collectively, the "Stockholders"), Comtrafo Indústria de Transformadores Elétricos S.A., an entity incorporated in Brazil ("Comtrafo"), Irineu Minato, an individual, solely in his capacity as the stockholder representative thereunder (the "Stockholder Representative"), the stockholder group members listed on Schedule I thereto (each, a "Stockholder Group Member" and collectively, the "Stockholder Group Members"), and the Company solely for purposes of Section 1.1(a), Article IV, Section 5.5 and Section 5.7 of the Stock Exchange Agreement.

Additionally on the Closing Date, pursuant to the terms of four separate Public Deeds of Purchase and Sale of Real Estate Property (each, a "Real Property Agreement<u>,</u>" and together, the "Real Property Agreements"), AMSC Brazil, through Comtrafo, purchased certain real estate assets that Comtrafo uses for administrative and manufacturing operations.

Pursuant to the Stock Exchange Agreement, AMSC Brazil, directly or indirectly acquired all of the issued and outstanding shares of Comtrafo, in exchange for (a) (i) 300,000,000 Brazilian Real in cash; and (b) 2,417,142 restricted shares of the Company's common stock, $0.01 par value per share (the "AMSC Shares") that were paid and issued, respectively, at closing. In addition, pursuant to the Real Property Agreements, AMSC Brazil through Comtrafo purchased certain real estate assets and transportation assets of Comtrafo for 155,564,538 Brazilian Real and 13,376,676 Brazilian Real, respectively, in cash. Additionally, AMSC Brazil has agreed to pay the Stockholders up to an additional 382,500,000 Brazilian Real in cash (the "Earnout") upon the achievement of specified earnings before interest, taxes, depreciation, and amortization ("EBITDA") objectives during the three years following the closing.

The unaudited pro forma condensed consolidated financial information contained herein is based on the historical financial statements of the Company, and the historical financial statements of Comtrafo, which are filed as Exhibit 99.1 and Exhibit 99.2 to this Current Report on Form 8-K/A, and has been adjusted to give effect to AMSC's acquisition of Comtrafo, which was accounted for under the acquisition method of accounting in accordance with Accounting Standards Codification ("ASC") 805, Business Combinations

The Comtrafo Acquisition will be accounted for as a business combination in accordance with accounting principles generally accepted in the United States of America ("US GAAP") (pursuant to Accounting Standards Codification Topic 805, Business Combinations ("ASC 805")), with AMSC treated as the "accounting acquirer." As a result of the Comtrafo Acquisition, AMSC controls Comtrafo as it beneficially owns 100% of the outstanding share capital of Comtrafo. The unaudited pro forma condensed combined financial statements were prepared in accordance with the acquisition method of accounting. Under the acquisition method of accounting, the purchase price is allocated to the identifiable tangible and intangible assets acquired and liabilities assumed based on their respective estimated fair values with any excess purchase price allocated to goodwill. Significant estimates and assumptions were used in determining the estimated purchase price and the preliminary purchase price allocation reflected in the unaudited pro forma condensed combined financial statements. The process of valuing the net assets of Comtrafo immediately prior to the business combination for purposes of presentation within this unaudited pro forma condensed combined financial information is preliminary. As the unaudited pro forma condensed combined financial statements have been prepared based on these preliminary estimates, the final amounts recorded may differ materially from the information presented.

The following unaudited pro forma condensed combined financial information is presented to illustrate the estimated effects of the Comtrafo Acquisition and the Megatran acquisition (as defined below).

The Comtrafo Acquisition is included in AMSC's historical results since December 5, 2025 as presented in AMSC's Quarterly Report on Form 10-Q for the interim period ended December 31, 2025. As a result, an Unaudited Pro Forma Condensed Combined Balance Sheet has not been presented. See Note 2 to the unaudited condensed consolidated financial statements within AMSC's Form 10-Q for the interim period ended December 31, 2025 for details of purchase consideration and the preliminary purchase price allocation. The unaudited pro forma condensed combined statements of operations for the year ended March 31, 2025, and the nine months ended December 31, 2025 are also based upon and derived from the historical financial information of the Company (as described in more detail below) and give effect to the Comtrafo Acquisition as if it had occurred on April 1, 2024. The unaudited pro forma condensed combined statements of operations for the year ended March 31, 2025 and the nine months ended December 31, 2025 are also based upon and derived from the historical financial information of Megatran Industries, Inc. ("Megatran"), which was acquired by the Company on August 1, 2024 (the "Megatran acquisition" and, together with the Comtrafo Acquisition, the "Transactions"). The unaudited pro forma condensed combined statements of operations for the year ended March 31, 2025 were adjusted to give effect to the Megatran acquisition as if it had occurred on April 1, 2024.

AMSC and Comtrafo have different fiscal year ends and prepare their financial statements under different accounting frameworks. Accordingly, the unaudited pro forma condensed combined statements of operations for the year ended March 31, 2025 combine AMSC's historical consolidated results for the year ended March 31, 2025 with Comtrafo's historical consolidated results for the year ended December 31, 2024. The unaudited pro forma condensed combined statements of operations for the nine months ended December 31, 2025 combine AMSC's historical consolidated results for the nine months ended December 31, 2025<sup>[1]</sup> with Comtrafo's historical consolidated results for the nine months ended September 30, 2025. These combinations reflect the differing fiscal periods of AMSC and Comtrafo and are presented solely to illustrate the effects of the Comtrafo Acquisition as if it had occurred on April 1, 2024.

<sup>[1]</sup> AMSC's historical consolidated results for the nine months ended December 31, 2025 include Comtrafo's results from Closing Date onwards i.e. from December 5, 2025 through December 31, 2025 and the Comtrafo historical consolidated results for the nine months ended September 30, 2025 include Comtrafo's results for the entire period. Management considered them as immaterial for the purposes of this ProForma presentation and accordingly did not adjust the AMSC historical results for any duplication. Comtrafo contributed $4.6 million of revenue and $0.9 million in net income for the Company for the nine months ended December 31, 2025.

Furthermore, Comtrafo has presented its financial information in accordance with International Financial Reporting Standards ("IFRS Accounting Standards") while AMSC follows US GAAP. As such, the unaudited pro forma condensed combined statements of operations for the twelve months ended December 31, 2024 and the nine months ended September 30, 2025 have been prepared by adjusting the historical financial information of Comtrafo from IFRS Accounting Standards to US GAAP. For more details, refer to Note 5.

The Megatran acquisition was a significant business acquisition as defined by Rule 3-05 and Article 11 of Regulation S-X, and, as a result, the Company filed with the Securities and Exchange Commission ("SEC") an 8-K/A on August 6, 2024, which included historical audited financial statements of Megatran as of and for the years ended December 31, 2023 and 2022 and unaudited pro forma condensed combined financial statements giving effect to the Megatran acquisition as of and for the year ended March 31, 2024 and for the three months ended June 30, 2024. Because both the Comtrafo Acquisition and the Megatran acquisition were deemed significant business acquisitions during the periods covered by unaudited pro forma condensed combined financial information, the pro forma information required by Item 9.01 of Form 8-K have been presented on a disaggregated basis due to the material nature of each such transaction.

The following unaudited pro forma condensed combined financial information has been prepared in accordance with Article 11 of Regulation S-X, as amended by the final rule, Release No. 33-10786 "Amendments to Financial Disclosures about Acquired and Disposed Businesses". Article 11 of Regulation S-X provides requirements to depict the accounting for the transaction ("Transaction Accounting Adjustments") and the option to present reasonably estimable synergies and other transaction effects that have occurred or are reasonably expected to occur ("Management's Adjustments"). AMSC has elected not to present Management's Adjustments in the unaudited pro forma condensed combined financial statements. The results set forth in the unaudited pro forma condensed combined financial information include adjustments that give effect to events that are directly attributable to the Comtrafo Acquisition.

The unaudited pro forma condensed combined financial statements should be read in conjunction with the accompanying notes to the unaudited pro forma financial information and:

● AMSC's historical financial statements and accompanying notes included in the Annual Report on Form 10-K for the year ended March 31, 2025;

● AMSC's historical financial statements and accompanying notes included in the Quarterly Report on Form 10-Q for the nine months ended December 31, 2025;

● Comtrafo's audited consolidated financial statements and accompanying notes for the year ended December 31, 2024, included as an exhibit in this Form 8-K/A;

● Comtrafo's unaudited consolidated interim financial statements and accompanying notes for the nine months ended September 30, 2025, included as an exhibit in this Form 8-K/A; and

● Megatran's unaudited combined financial statements for the six months ended June 30, 2024, included in AMSC's Current Report on Form 8-K/A (File No. 000-19672).

The pro forma financial information is presented for illustrative purposes only and does not necessarily reflect what the combined company's financial position or results of operations would have been, had the Transactions and the related financings occurred on the dates indicated. They also may not be useful in predicting the future financial condition and results of operations of the combined company. The unaudited pro forma condensed combined financial statements do not include the realization of any cost savings from operating efficiencies, synergies or other activities, or the recognition of any cost increases or dis-synergies that might result from the Transactions. The Company's actual financial condition and results of operations may differ significantly from the pro forma amounts reflected herein due to a variety of factors.

**Notes to Unaudited Pro Forma Condensed Combined Financial Information** 

**Note 1** – **Description of the Transaction**

On December 5, 2025, American Superconductor Corporation completed the acquisition of Comtrafo Indústria de Transformadores Elétricos S.A. pursuant to the Stock Exchange Agreement. Under the terms of the Stock Exchange Agreement, AMSC acquired, directly or indirectly, all of the issued and outstanding share capital of Comtrafo in exchange for an aggregate purchase price of $202.7 million, consisting of:

---

| | |
|:---|:---|
| Cash payments | $88.3 |
| Issuance of 2,417,142 shares of Company's common stock | 78.5 |
| Contingent consideration | 35.9 |
| Total consideration | 202.7 |

---

Contemporaneously, real estate facilities, with over 100 acres of land, leased by Comtrafo for its factory operations, were purchased through the Real Property Agreements as part of the cash payment above. The total consideration payable pursuant to the above agreements aggregated $202.7 million and the above agreements were accounted for as a single business combination, in accordance with ASC Topic 805. The Company will record the assets acquired and liabilities assumed at their respective fair values as of the acquisition date. Due to the timing of the acquisition, the Company's purchase accounting related to the valuation of the inventory, fixed assets, intangible assets, goodwill and liabilities assumed is not yet complete and subject to revision.

On August 1, 2024, AMSC had consummated the Megatran acquisition, of which AMSC paid $30,000 thousand of cash and issued 1,297,600 shares of AMSC common stock to acquire all of the issued and outstanding shares of Megatran, based on the shares in issue as of August 1, 2024.

**Note 2** – **Basis of presentation**

The unaudited pro forma condensed combined financial information and related notes are prepared in accordance with Article 11 of Regulation S-X, as amended by the final rule, Release No. 33-10786 "Amendments to Financial Disclosures about Acquired and Disposed Businesses".

The unaudited pro forma financial information below combines the effects of the Stock Exchange Agreement and the Real Property Agreements, as these were negotiated as a single transaction and signed in contemplation of each other and together constitute the Comtrafo Acquisition. The Comtrafo Acquisition will be accounted for under the acquisition method of accounting for business combination pursuant to the provisions of ASC 805 with AMSC treated as the "accounting acquirer". As a result of the Comtrafo Acquisition, AMSC controls Comtrafo as it beneficially owns 100% of the outstanding share capital of Comtrafo. Under the acquisition method of accounting, the estimated purchase price will be allocated to Comtrafo assets acquired and liabilities assumed based upon their estimated fair values, using the fair value concepts defined in ASC Topic 820, *Fair Value Measurement*, at the Acquisition Date. Any excess of consideration transferred over the preliminary estimate of the fair value of identified assets acquired and liabilities assumed will be recognized as goodwill. Significant judgment is required in determining the preliminary fair values of identified intangible assets, property, plant and equipment, inventories, certain other assets, and assumed liabilities. These preliminary valuations of assets acquired, and liabilities assumed are determined using market, income and cost approaches from the perspective of a market participant, which requires estimates and assumptions including, but not limited to, estimating future cash flows in addition to developing the appropriate market discount rates and obtaining available market pricing for comparable assets. The final valuation may materially change the allocation of the purchase price, which could materially affect the fair values assigned to the assets and liabilities and could result in a material change to the unaudited pro forma condensed combined financial information.

The historical audited and unaudited consolidated financial statements of AMSC were prepared in accordance with US GAAP and presented in U.S. dollars. The historical audited consolidated financial statements and unaudited consolidated interim financial statements of Comtrafo were prepared in accordance with IFRS Accounting Standards and presented in Brazilian Real ("BRL"). As such, the unaudited pro forma condensed combined statements of operations have been prepared by adjusting the historical financial information of Comtrafo from IFRS Accounting Standards to US GAAP. Refer to Note 5 for more details on such adjustments.

The following unaudited pro forma condensed combined financial information presents the combination of the financial information of AMSC and Comtrafo adjusted to give effect to the Comtrafo Acquisition and other events contemplated by the Stock Exchange Agreement as described herein. The unaudited pro forma condensed combined statements of income for the nine months ended December 31, 2025, and the year ended March 31, 2025, combines the historical statements of income of AMSC and Comtrafo on a pro forma basis assuming the Comtrafo Acquisition had occurred on April 1, 2024, the beginning of the earliest period presented. Furthermore, since Eletrotrafo was not acquired as part of the Comtrafo Acquisition, Eletrotrafo's income and expenses were eliminated as part of Transaction Accounting Adjustments.

In addition, the unaudited pro forma condensed combined statements of operations (AMSC) for the year ended March 31, 2025 and the nine months ended December 31, 2025, are also based upon and derived from the historical financial information of Megatran, which was combined with the Company on August 1, 2024. The unaudited pro forma condensed combined statements of operations for the year ended March 31, 2025, was adjusted to give effect to Megatran acquisition as if it had occurred on April 1, 2024.

The unaudited pro forma condensed combined financial information is not necessarily indicative of what the actual results of operations and financial position would have been had the Transactions taken place on the dates indicated, nor are they indicative of the future consolidated results of operations or financial position of AMSC and they are based on the information available at the time of their preparation. Actual results may differ materially from the assumptions within the unaudited pro forma condensed combined financial information.

The unaudited pro forma condensed combined financial information is intended to provide information about the impact of the Transactions as if it had been consummated earlier. The pro forma adjustments are based on available information and certain assumptions that management believes are factually supportable and are expected to have an impact on AMSC's results of operations. In the opinion of management, all adjustments necessary to present fairly the unaudited pro forma condensed combined financial statements have been made.

**Accounting policies and reclassification**

For the purposes of preparing the unaudited pro forma condensed combined financial information, AMSC conducted a preliminary review of Comtrafo's accounting policies to identify significant differences. Based on its preliminary review, management identified certain accounting policy differences that were presented within the US GAAP adjustments and also certain reclassification adjustments to conform Comtrafo's historical financial statements presentation to AMSC's financial statement presentation (refer Note 5 for details). Management will perform a comprehensive review of Comtrafo's accounting policies. As a result of the review, management may identify differences between the accounting policies or financial statement classification of the two businesses which, when conformed, could have a material impact on the consolidated financial statements of Comtrafo and AMSC.

**Note 3** – **Transaction accounting adjustments**

The following pro forma adjustments (including eliminations) are included in the unaudited condensed combined pro forma statements of operations:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) To <u> </u> record an adjustment to remove balances associated with Eletrotrafo as Eletrotrafo was not acquired as part of the Comtrafo Acquisition. The following table presents Eletrotrafo's unaudited Statement of Operations for the nine months ended September 30, 2025, and the year ended December 31, 2024:

Eletrotrafo's historical results are presented separately solely to illustrate the elimination of its results, as it was excluded from the Comtrafo Acquisition.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) Comtrafo's property, plant, and equipment were accounted for at fair value at the date of acquisition. Furthermore, right-of-use assets and lease liabilities were derecognized as the related real estate properties were acquired as part of the transaction and are now presented within property, plant, and equipment. The related depreciation expense includes an adjustment to the unaudited condensed combined pro forma statements of operations as below:

● A net adjustment of $1,502 thousand to cost of revenues and $207 thousand to selling, general, and administrative for the year ended March 31, 2025, to (1) reflect the removal of historical depreciation expense of $378 thousand related to cost of revenues and $52 thousand related to selling, general and administrative and (2) recognize depreciation of $1,880 thousand related to cost of revenues and $259 thousand related to selling, general and administrative expenses.

● A net adjustment of $1,101 thousand to cost of revenues and $170 thousand to selling, general, and administrative for the nine months ended December 31, 2025, to (1) reflect the removal of historical depreciation expense of $291 thousand related to cost of revenues and $45 thousand related to selling, general and administrative and (2) recognize depreciation related to tangible assets of $1,392 thousand related to cost of revenues and $215 thousand related to selling, general and administrative expenses. The historical lease expenses of $874 thousand and $742 thousand for the year ended March 31, 2025, and the nine months ended December 31, 2025, respectively, were reversed from cost of revenues

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) The following table summarizes the preliminary estimated fair values of Comtrafo's identifiable intangibles assets as of the acquisition date, and their estimated useful lives, along with the estimated amortization expense calculated using the economic consumption method of amortization:

---

|:---|:---|:---|:---|:---|
| **(USD in thousands)** | **Estimated**<br> **fair value** | **Estimated**<br> **Useful**<br> **Life (months)** | **Amortization for nine months ended December 31, 2025** | **Amortization for year ended March 31, 2025** |
| **Intangible asset** |  |  |  |  |
| Backlog | $1772 | 16 | 443 | 1329 |

The historical amortization expense for the year ended March 31, 2025, and the nine months ended December 31, 2025, has been eliminated and amortization expense associated with the acquired intangible assets has been recorded within cost of revenues for backlog and within operating expenses for customer relationships.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) To record an estimated income tax benefit on pro forma adjustments to income related to the Comtrafo Acquisition, at 34% effective tax rate for the respective periods i.e. 16% for the year ended March 31, 2025 and 28% for the nine months ended December 31, 2025.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e) To reflect an increase in the weighted average shares outstanding for the period after giving effect to the issuance of AMSC common stock in connection with the Comtrafo Acquisition.

| Contractual relationships / backlog | $700000 |  |  |
| Total cost of revenues amortization of intangible |  |  |  |
| Customer relationships | 1280000 | 10 | 42667 |
| Total selling, general and administrative amortization of intangibles |  |  | 42667 |
| **Total costs in excess of tangible assets** |  |  | $42667 |

---

**Transaction accounting adjustments:**

The pro forma adjustments included in the unaudited pro forma condensed combined financial information are as follows (amounts in thousands):

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) To record the amortization expense associated with acquired intangible assets including Contractual relationships/backlog and Customer relationships for the fiscal year ended March 31, 2025. Since the Megatran Acquisition occurred on August 1, 2024, AMSC's historical income statements already include amortization expenses for backlog and customer relationships for 8 months (historical amortization). Hence, all amortization expenses related to backlog is already included in AMSC's income statement for the year ended March 31, 2025.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) To record an estimated income tax benefit on pro forma adjustments to income related to the Megatran acquisition, at 23.74% effective tax rate.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) To reflect an increase in the weighted average shares outstanding for the period after giving effect to the issuance of AMSC common stock in connection with the Megatran acquisition.

**Note 5** – **Reclassification and US GAAP Adjustments**

Comtrafo's historical financial statements have been prepared in accordance with IFRS Accounting Standards, which differs in certain material respects from US GAAP. In order to prepare pro forma financial statements, Comtrafo's historical financial statements have been adjusted to reflect Comtrafo consolidated statements of operations on a US GAAP basis by recording appropriate adjustments ("US GAAP adjustments").

During the preparation of this unaudited pro forma condensed combined financial information, management performed a preliminary review of Comtrafo's financial information to identify US GAAP adjustments, differences in accounting policies and financial statement presentation as compared to those of AMSC. At the time of preparing the unaudited pro forma condensed combined financial information, AMSC was not aware of any material differences other than the adjustments described herein. However, AMSC will continue to perform its detailed review of Comtrafo accounting policies, including convergence of its accounting policies to US GAAP. Upon completion of that review, differences may be identified between the accounting policies of the two businesses that, when confirmed, could have a material impact on the unaudited pro forma condensed combined financial information.

**Notes to US GAAP adjustments:**

&nbsp;&nbsp;&nbsp;&nbsp;**a)** **Operating leases** 

In Comtrafo's historical consolidated financial statements, leases were recognized on the balance sheet as right-of-use assets and lease liabilities, in accordance with IFRS Accounting Standards. The right-of-use asset was depreciated over the lease term on a straight-line basis, with the impact recorded in the income statement as depreciation expense within cost of revenues. The lease liability was amortized using the incremental borrowing rate, and the impact was recorded in the income statement as interest expense within net interest income.

Under US GAAP, operating lease expense is recognized on a straight-line basis over the term of the lease.

The following adjustments were made to the statements of operations:

---

| | | |
|:---|:---|:---|
| **(BRL in thousands)** | **For the year ended December 31, 2024** | **For the nine-months ended September 30, 2025** |
| Reversal of historical amortization expense under IFRS | (3973) | (3674) |
| Recognition of lease expense under US GAAP | 4689 | 4192 |
| **Cost of revenues (net impact)** | **716** | **518** |

---

Additionally, for the twelve months ended December 31, 2024, and the nine months ended September 30, 2025, historical interest expense of BRL 593 thousand and BRL 402 thousand, respectively, was reversed.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**b)** **Reclassification adjustments** 

Represents reclassifications of historical Comtrafo financial statement line items to conform to the expected financial statement line items of the combined company following the Comtrafo Acquisition.
