18/47 (a) exceeds the Preliminary Purchase Price, the Purchaser shall pay to the Seller an amount equal to such excess; and (b) falls short of the Preliminary Purchase Price, Seller shall pay to Purchaser an amount equal to such shortfall; (any such amount to be paid by Purchaser or Seller according to this Clause 4.3.2, the "Purchase Price Adjustment") 4.3.3 The Purchase Price Adjustment shall be due for payment within 3 (three) Business Days after the Purchase Price Documentation has become final and binding in accordance with Clause 4.3.1. 4.3.4 The Purchase Price Adjustment shall not bear any interest until the date on which the Purchase Price Adjustment becomes due under Clause 4.3.3. 4.4 Purchase Price for the GP-Share The purchase price for the GP-Share shall amount to EUR 35,000.00 (Euro thirty- five thousand) ("GP-Share Purchase Price"). 4.5 Payment of the Preliminary Purchase Price and the GP-Share Purchase Price at Closing / Payments 4.5.1 The Preliminary Purchase Price and the GP-Share Purchase Price shall be due and payable at Closing and shall be paid by the Purchaser to the Seller's Bank Account. 4.5.2 The payment of the Preliminary Purchase Price and the GP-Share Purchase Price and all payments to be made pursuant to this Agreement, shall be made when due by irrevocable SWIFT wire transfer of immediately available funds, free and clear of all costs, fees, deductions and charges, less any withholdings required under applicable laws, if any, in EUR. 4.5.3 Except as expressly set forth otherwise in this Agreement or any Exhibits hereto, all payments to be made by the Purchaser pursuant to this Agreement shall be made to the Seller's Bank Account. 4.5.4 Any failure by any Party to make any payment pursuant to this Agreement when it is due shall result in such Party’s immediate default, without any reminder by the other Party being required. The amount of any payment which is overdue shall be subject to late payment interest of 9 (nine) percentage points above the base interest rate (Basiszinssatz) p.a. Further claims and remedies of the other Party in connection with such failure shall remain unaffected. In the event that a late payment is due to a receiving bank not having completed its KYC/AML procedures with regard to the sender of funds, despite the sender having provided all documents and information so requested by the receiving bank, such late payment shall not result in late interest and the Party, whose payment is delayed shall complete the KYC/AML procedure as soon as reasonably possible.

19/47 4.6 VAT Any sum payable (in cash or in kind) by the Purchaser to the Seller under or pursuant to this Agreement is exclusive of any applicable VAT. The Seller undertakes not to waive a VAT exemption in respect of any supply under or pursuant to this Agreement. If any VAT is or becomes chargeable on any supply made by the Seller under or pursuant to this Agreement for which the Seller is required to account, the Purchaser shall, subject to the receipt of a VAT invoice complying with applicable Legal Provisions, pay to the Seller (in addition to any other consideration for that supply) an amount equal to such VAT. 4.7 Capital Maintenance If, after Closing, the Target Company enforces any claims against the Seller or its Affiliates resulting from a violation of the prohibition on returning contributions (Verbot der Einlagenrückgewähr) for periods up to and including the Closing Date, the Purchaser shall pay to the Seller (as an increase of the Purchase Price) such amount that the Seller or its Affiliates have actually paid to the Target Company (net of any Taxes incurred by the Target Company as a result of violation of the prohibition on returning contributions). 5. Representations and Warranties of the Seller The Seller represents and warrants (leistet Gewähr) to the Purchaser that the representations and warranties as set out in Exhibit 5 are correct and complete, unless expressly stated otherwise in Exhibit 5, as of Signing and Closing. 6. Indemnification 6.1 Indemnification by the Seller 6.1.1 Subject to the provisions of this Clause 6, the Seller shall indemnify and hold the Purchaser or, at the Purchaser's sole discretion, the Target Company harmless on a EUR-per-EUR basis from and against any Loss suffered or incurred by the Purchaser or the Target Company as a result of, arising out of or relating to any breach of any of the Seller's Representations and Warranties under or pursuant to this Agreement. 6.1.2 If and to the extent that any of the Seller's Representations and Warranties hereunder is incorrect or incomplete, the Seller shall put the Purchaser or the Target Company, as the case may be, into the position they would have been in had the representation or warranty not been breached (restitution in kind; Naturalrestitution). If the Seller is unable to achieve this position within 60 (sixty) days after having been notified by the Purchaser of the breach (Clause 6.2) or the Seller in its sole discretion deems such restitution in kind not feasible, the Purchaser shall be entitled to claim payment of the amount of the Loss pursuant to Clause 6.1.1.

20/47 6.1.3 If and to the extent a Loss is the result of an obligation or liability of the Target Company the non-existence of which has been represented or warranted, the Purchaser's Warranty Claim pursuant to this Clause 6 shall be equal to an amount which the Purchaser or the Target Company have to pay in order to fully settle, discharge and satisfy this obligation or liability. 6.1.4 The Purchaser shall have a duty to mitigate losses and damages (Schadensminderungspflicht) in respect of any damages and losses. Following the Closing, any failure by the Target Company to mitigate losses and damages shall be deemed a breach of the Purchaser's duty to mitigate losses and damages. If the Purchaser breaches its duty to mitigate losses and damages, any claim or Warranty Claim of the Purchaser shall be reduced by the amount of the loss or damage which results from such breach. The duty to mitigate any loss or damage shall in particular include the obligation of the Purchaser to give the Seller the opportunity to remedy the loss or damage by restitution in kind (Naturalrestitution) within the period stated in Clause 6.1.2 and to prevent any potential future loss or damage. 6.1.5 Each of the Seller's Representations and Warranties is limited to the scope of the statements contained in such Seller's Representation and Warranty itself. 6.1.6 To the extent permitted by law, any further claims and remedies, other than explicitly provided for under Clause 5, Clause 6, Clause 7, Clause 8 or Clause 9 of this Agreement, irrespective of which nature, amount or legal basis, are hereby expressly waived and excluded, in particular, without limitation, claims under contractual and pre-contractual fault (Pflichtverletzung aus dem Schuldverhältnis und dem vorvertraglichen Schuldverhältnis), positive breach of contract (Positive Vertragsverletzung) and/or the right to rescind this Agreement (Rücktritt or Wandlung), and any liability in tort (Deliktshaftung). Furthermore, the Parties explicitly waive the right to rescind or to adjust the Agreement on the grounds of error (Irrtum) or frustration of contract (Wegfall der Geschäftsgrundlage) or an adjustment of the Agreement based on any other grounds. The right to void (anfechten) or rescind (aufheben) this Agreement pursuant to Section 934 ABGB (Verkürzung über die Hälfte) shall be excluded. Sections 922–932, including in particular Section 924 2nd sentence, and Section 933a ABGB shall not apply. 6.1.7 It is expressly agreed by the Parties that no direct or indirect damage, loss, lost profits, costs, disadvantage, taxes, circumstance, action or event in connection with or as a consequence of the conversion pursuant to the conversion agreement dated 1 December 2025, by which voestalpine ▇▇▇▇▇▇ Profil GmbH, as the transferring entity, was converted by way of a conversion by formation into voestalpine ▇▇▇▇▇▇ Profil GmbH & Co KG (Target Company), as registered in the Austrian companies register on 02.12.2025 (02 December 2025) ("Conversion") being successfully challenged or terminated by a Tax Authority, shall entitle the Purchaser to (i) any Warranty Claim according to Clause 5 or a claim under the Tax Indemnity according to Clause 7 or any other claims of whatsoever nature and based on whichever title, from the Purchaser against the Seller (or its Affiliates) or (ii) a reduction of the Purchase Price (in particular according to Clause 4 or otherwise) and any such claims are expressly excluded and waived by the Purchaser. This exclusion and

21/47 waiver of any such claims according to the preceding sentence shall also apply if the Conversion is deemed void or voidable or otherwise legally flawed under Austrian corporate or civil law and shall also apply to Seller's Representations and Warranties, which do not refer to the Conversion but which may be rendered incorrect and/or incomplete due to any legal and/or factual defect of the Conversion. 6.2 Notice of Breach If the Purchaser becomes aware of any matter or circumstance that may give rise to a Warranty Claim against the Seller under this Agreement, the Purchaser shall within 30 (thirty) days after having obtained information about the matters giving rise to a potential Warranty Claim give notice in writing to the Seller, setting out the nature of the relevant claim, its factual and legal basis and – to the extent already known – the amount of the Loss involved. The failure of the Purchaser to fully comply with its obligations under this Clause 6.2 shall in any case be deemed a breach of the Purchaser's duty to mitigate losses and damages under Clause 6.1.4. but shall not act as a preclusion of the Purchaser's claims hereunder. 6.3 Limitation Periods All Warranty Claims of the Purchaser for breach of the Seller's Representations and Warranties shall become time-barred 18 (eighteen) months after the Closing Date, except for Warranty Claims for breach of Fundamental Warranties, which shall become time-barred 5 (five) years after the Closing Date and Warranties in relation to Taxes, which shall become time barred 90 (ninety) days following the end of the statutory limitation period (including any extensions, suspensions, or interruptions thereof) applicable to the relevant Legal Provisions so that the relevant Tax is final and non-appealable. For the avoidance of doubt, the limitation period shall be deemed to be extended for the duration of any audit, investigation, assessment, litigation, appeal, or other proceeding initiated by any Tax Authority or court in respect of the relevant Tax, and shall not expire until 90 (ninety) days after the final, non-appealable resolution of such proceeding and the expiry of any period for reopening or reassessment under applicable Legal Provisions. 6.4 Suspension 6.4.1 If the Purchaser asserts any Warranty Claim arising under this Agreement by written Notice to the Seller in accordance with Clause 6.2, the time-barring of such Warranty Claim shall be suspended (gehemmt). The suspension shall expire after 4 (four) months unless the Purchaser asserts the respective Warranty Claim in court before the expiry of this period. Any suspension under a Legal Provision remains unaffected. 6.4.2 Pending settlement negotiations shall only suspend the time-barring of a Warranty Claim if the Parties agree so in writing. In this case, the suspension shall end upon one of the Parties declaring the settlement negotiations to be terminated by written Notice to the other Party.

22/47 6.5 De Minimis Amount; Threshold The Purchaser shall not be entitled to any Warranty Claims under or in connection with this Agreement if and to the extent (i) an individual Warranty Claim does not exceed an amount of EUR 50,000.00 (Euro fifty thousand) (the "De Minimis Amount") and (ii) the aggregate amount of individual Warranty Claims does not exceed an amount of EUR 400,000.00 (Euro four hundred thousand) (the "Threshold"). Individual Warranty Claims not exceeding the De Minimis Amount shall be excluded for the purposes of determining whether the Threshold is exceeded or not. In case the Threshold is exceeded, the Seller shall be liable for the amount in excess of the Threshold (Freibetrag). For avoidance of doubt, the De Minimis Amount and the Threshold do not apply to Tax Claims, Customer Warranty Claims, voestalpine Equity Plan Indemnity Claims and Variable Employment Payment Indemnity Claims. 6.6 Liability Cap The Seller's aggregate liability under or in connection with this Agreement, including without limitation for breaches of the Seller's Representations and Warranties pursuant to Clause 5, Tax Claims, Customer Warranty Claims, claims under the voestalpine Equity Plan Indemnity and Variable Employment Payment Indemnity Claims, shall in the aggregate (in total) not exceed an amount equal to 17.5 % (seventeen point five percent) of the Purchase Price (the "Cap"). The Cap shall not apply to Warranty Claims of the Purchaser relating to a breach of the Fundamental Warranties, if any, for which the Seller's liability shall be limited to the Purchase Price actually received by the Seller under this Agreement. 6.7 Purchaser's Knowledge 6.7.1 The Purchaser shall not be entitled to assert any claim arising out of or in connection with this Agreement or otherwise to the extent that, on the Signing Date, the facts, matters, events, information or circumstances to which the respective claim relates have been fairly disclosed to the Purchaser or its Representatives as Disclosed Materials (the "Purchaser's Knowledge"). For the purposes of this Section 6.7, "fairly disclosed" means that facts or circumstances are provided in the Disclosed Materials in such manner, including by way of Q&A and references to answers given and documents provided in the Data Room, as can be reasonably expected from an objective point of view and in such manner that a reasonable professional buyer of the Target Company, assisted by professional advisors, could understand the relevance of such facts or circumstances. 6.7.2 The Purchaser confirms that it has inspected all publicly available information registers in connection with the Target Company and the Real Properties, including the land register, the commercial register and the cadastral map of contaminated

23/47 sites atlas (Altlastenatlas). All information in this Clause 6.7 is considered Purchaser's Knowledge. 6.8 Limitation of Liability / No Other Sellers' Warranties 6.8.1 The Purchaser agrees to purchase and acquire the Share (and the GP-Share) based upon its own review, inspection, examination and determination of the Disclosed Materials and without reliance upon any express or implied representations, warranties or guarantees of any nature made by or on behalf of or imputed to the Seller except for the representations and warranties explicitly given by the Seller under the Agreement. 6.8.2 Without limiting the generality of Clause 6.8.1, the Purchaser acknowledges that the Seller gives no representation, warranty or guarantee with respect to any projections, estimates or budgets delivered or made available to the Purchaser of future revenues, future results of operations (or any component thereof), future cash flows or future financial conditions (or any component thereof). 6.8.3 Seller's liability under or in connection with this Agreement shall not exist if and to the extent that or shall be reduced to the extent that 6.8.3.1 the Loss is caused by an action or omission agreed to in this Agreement or otherwise with respect to any facts, matters, events or circumstances requested or approved in writing by Purchaser; 6.8.3.2 the Loss arises or is magnified by Purchaser's failure to perform its obligations under this Agreement or its duty to mitigate losses and damages; 6.8.3.3 provisions, reserves (Rückstellungen) or other provision have been made in the Closing Date Accounts reflecting facts or circumstances in relation to the Loss; 6.8.3.4 such liability would not have occurred but for an enactment or amendment of Legal Provisions or case law subsequent to the Signing of this Agreement. 6.8.4 The Seller shall not be liable for any Warranty Claim to the extent that the Loss serving as the basis of the Warranty Claim results from the Purchaser’s breach of any of the Purchaser’s undertakings provided in the Agreement or in the documents provided by the Purchaser. 6.8.5 If a Tax Claim is excluded according to Clauses 6.1.7, 7.2, or 7.3, this exclusion shall also apply to any and all Warranty Claims under any of the Seller's Representations and Warranties according to Clause 5, also if such Seller's Representations and Warranties do not refer to Tax issues but are rendered incorrect and/or incomplete due to the same facts or circumstances. 6.8.6 The amount of any Losses with respect to a Warranty Claim for which the Seller is liable shall be net of any amounts actually recovered by the Purchaser or the Target Company under insurance policies (net of any Tax or expenses incurred in

24/47 connection with such recovery). The Purchaser shall actively and diligently pursue recovery under all applicable insurance policies and take all reasonable actions necessary to procure such recovery (for the avoidance of doubt, this does not include the duty to initiate litigation). The Purchaser may notify the Seller of a Warranty Claim against the Seller in accordance with Clause 6.2, but only recover on such Warranty Claim once insurance coverage is finally denied. While the Purchaser is seeking recovery under insurance, the time-barring of the Warranty Claim in accordance with Clause 6.4 shall be suspended until the earlier of (i) the insurance finally denies coverage, or (ii) Purchaser ceases to actively and diligently pursue coverage under the insurance. 6.9 Third Party Claims 6.9.1 If a Warranty Claim notified pursuant to Clause 6.2 is a result of or in connection with a claim or demand (including, without limitation, any claim for breach of any of Seller's Representations and Warranties relating to Taxes by or liability to a Third Party, including, without limitation, any (Tax) Authority), in respect of which indemnification may be sought pursuant to this Agreement ("Third Party Claim"), the Purchaser shall, or shall procure that the Target Company will send a Notice to the Seller that a Third Party Claim has been asserted, within 14 (fourteen) Business Days after having received such Third Party Claim, stating, in reasonable detail, the nature of the relevant claim, its factual and legal basis and – to the extent already known – the amount of the Loss involved ("Third Party Claim Notice"). For the avoidance of doubt, a Third Party Claim shall expressly include any measures, orders or proceedings by any authority aimed at the recovery of assets obtained as a result of alleged unlawful conduct (Vermögensabschöpfung), including, without limitation, the recovery of purchase price proceeds from goods sold or exported in violation of any applicable Sanction Laws; any Loss arising therefrom shall be indemnifiable in accordance with this Clause 6.9.1. 6.9.2 The Purchaser shall 6.9.2.1 keep the Seller promptly informed of the progress of the Third Party Claim and provide the Seller with copies of all the relevant documents and such other information in its possession as may be reasonably requested by the Seller; 6.9.2.2 refrain from acting to the detriment of the Seller, in particular in respect to claim settling or otherwise acknowledging any such Third Party Claim, unless it has obtained prior consent of the Seller; 6.9.2.3 promptly allow and/or procure that the Target Company promptly allows the Seller at its own cost to participate, to the extent permitted by applicable laws, in particular as an incidental intervener (Nebenintervenient) in the conduct of a dispute, arbitration, negotiations, defense or appeal against a given Third Party Claim and/or procure that the Target Company performs all activities aimed at enabling the Seller to participate in the proceedings on Third Party Claims, if it so wishes provided that the Seller reimburses the Target Company for any external cost incurred due to specific written requests of the Seller;

25/47 6.9.2.4 promptly allow and/or procure that the Target Company promptly allows the Seller at its own cost to defend the Third Party Claim by all appropriate proceedings and the Seller shall have the sole power to direct and control such defense. In particular, without limitation, the Seller may (i) participate in and direct all negotiations and correspondence with the third party, (ii) appoint and instruct the counsel acting, if necessary, in the name of the Target Company or the Purchaser (as the case may be), and (iii) require that the Third Party Claim be litigated or settled in accordance with the Seller's instructions, if it so wishes; and 6.9.2.5 coordinate with Seller and ask Seller for prior written approval regarding all actions taken by Purchaser or the Target Company that relate to any Third Party Claim. In addition, if requested by Seller, Purchaser must take all reasonable steps, actions or proceedings necessary to mitigate or defend any Third Party Claim and enforce all rights of the Target Company and the Purchaser against any person (other than the Seller) in relation to the subject matter of the Third Party Claim provided that the Seller reimburses the Target Company for any external cost incurred due to specific written requests of the Seller. 7. Tax Indemnity 7.1 The Seller shall indemnify and hold harmless the Purchaser or, at the Purchaser’s discretion, the Target Company on a EUR-per-EUR basis against: any Taxes of the Target Company arising in respect of (i) any taxable period (Veranlagungszeitraum) or any time period (or any portion thereof) ending on or before the Closing Date; or (ii) any Taxes for which the Target Company becomes liable after Closing by reason of any event occurring on or before the Closing Date or by reason of its membership or inclusion in any tax consolidation, fiscal unity, tax group or similar arrangement with the Seller or any of its Affiliates (including the Austrian VAT Group and CIT Group) with respect to periods ending on or before the date of leaving the respective group ("Tax Indemnity" and each claim under (i) and (ii) a "Tax Claim"). 7.2 The Seller’s obligation to indemnify the Purchaser or, at the Purchaser’s discretion, the Target Company, under this Clause 7 and especially Clause 7.1 shall not apply if and to the extent that: (i) Taxes have been paid or otherwise been settled before or on the Closing Date, provided and to the extent such Taxes were taken into account in the Closing Date Accounts; (ii) Taxes have been taken into account in the Closing Date Accounts as a liability for Taxes or provision for Taxes; (iii) with respect to Taxes the Target Company has to withhold any amounts under Legal Provisions but in relation to which a third party is liable and the Target Company is actually refunded by such third party for such amounts (it being agreed that the Purchaser shall procure that the Target Company uses commercially reasonable efforts to collect any such refund);

26/47 (iv) an actual and quantifiable cash Tax benefit becomes available to the Purchaser or the Target Company resulting as a consequence of a Tax audit of the Target Company whereby such Tax benefits shall only be taken into account up to the amount previously indemnified by the Seller in the event it results in cash Tax benefits that become payable by 31.12.2030 (31 December 2030) unless these have already been considered in the Closing Date Accounts and resulting Purchase Price calculation or where Seller, a Seller Affiliate or voestalpine AG has already benefited, or will benefit, from such matter (for example by a reduction of the taxable capital gain (Veräußerungsgewinn) crystallizing upon the sale of the Share; (v) with respect to Taxes, which were caused or increased after or on the Closing Date by an agreement or other measure or action taken by the Purchaser or the Target Company on or after the Closing Date, but with retroactive effect as of the Closing Date or at a time prior to the Closing Date except the agreement or other measure or action were taken in the course of corrections of errors by the Target Company or required by law. 7.3 Any claim excluded in accordance with Clause 6.1.7 shall not be indemnifiable by the Seller to the Purchaser including but not limited to a case where such Taxes are paid by the Target Company under the Tax Allocation Agreement. 7.4 In the event and to the extent that the Conversion (as defined in Clause 6.1.7) results in taxable income at the level of the legal predecessor of the Target Company which is allocable to voestalpine AG as head of the CIT Group, voestalpine AG shall charge Taxes on such taxable income to the Target Company as stipulated under the Tax Allocation Agreement (for the avoidance of doubt, this does not include the duty to initiate litigation). In the event that the Target Company for any reason refuses (including, without limitation, due to lack of liquidity/funds) payment under the Tax Allocation Agreement either (i) despite such claims being reimbursable under the Tax Allocation Agreement; or (ii) due to the Tax Allocation Agreement not applying after Closing the Purchaser shall reimburse voestalpine AG for any such amounts not reimbursed by the Target Company. The obligation of the Purchaser to reimburse the respective entity of the voestalpine Group shall be interpreted as an obligation in favor of third parties (echter Vertrag zugunsten Dritter). For the avoidance of doubt this Clause shall only apply to Taxes that are or should have been reimbursable by the Target Company (or its legal predecessor) under the Tax Allocation Agreement in application of the principles set out above. The same shall apply in the event and to the extent that the Conversion triggers VAT and such VAT is imposed at the level of voestalpine AG as head of the VAT Group in case that such VAT is not reimbursed to voestalpine AG from the Target Company, by way of the operation of the VAT Group. At the request of the Target Company, voestalpine AG, to the extent legally permissible, undertakes to issue an invoice in line with sec 11 or sec 12 (15) VAT Act (Umsatzsteuergesetz) as required by Target Company to recover such VAT as input VAT (Vorsteuer). For the obligation of the Purchaser under this Clause 7.4, Clause 7.7 applies mutatis mutandis.

27/47 7.5 Conduct of Tax Matters, Tax audits, assessments, claims and other proceedings that could reasonably give rise to a claim under this Tax Indemnity shall be handled in accordance with Clause 6.9 (Third Party Claims) and Clause 7.10 (Cooperation in Tax issues). For any Taxes relating to periods ending on or before the Closing Date, the Seller shall have the rights set out in Clause 7.10 to control or participate in such proceedings to the extent they affect Taxes for which the Seller may be liable under this Agreement. 7.6 Payment Mechanics. Amounts due under this Tax Indemnity shall be paid in cash: (i) 5 (five) Business Days prior to the due date for payment of the underlying Tax to the relevant Tax Authority, if the Tax has not yet been paid; or (ii) within 10 (ten) Business Days after receipt of a written demand (with reasonable supporting details) if the Tax has already been paid by the Purchaser or the Target Company. If and to the extent the Seller indemnifies the Purchaser and the Tax Indemnification Claim is subsequently reduced, such reduction amount shall be reimbursed by the Purchaser to the Seller, including all interest received thereon, within 10 (ten) Business Days following the receipt of the reduction amount by the Purchaser or the Target Company. 7.7 This Tax Indemnity shall become time-barred (verjährt) upon the expiry of 90 (ninety) days following the end of the statutory limitation period (including any extensions, suspensions, or interruptions thereof) applicable to the relevant Legal Provisions so that the relevant Tax is absolutely final and non-appealable and, therefore, can no longer be assessed and/or collected by any Tax Authority or Third party. For the avoidance of doubt, the limitation period for any Tax Claim shall be deemed to be extended for the duration of any audit, investigation, assessment, litigation, appeal, or other proceeding initiated by any Tax Authority or court in respect of the relevant Tax, and shall not expire until 90 (ninety) days after the final, non-appealable resolution of such proceeding and the expiry of any period for reopening or reassessment under applicable Legal Provisions. 7.8 For the avoidance of doubt: (i) this Tax Indemnity does not apply to VAT on supplies under this Agreement, which is governed by Clause 4.6 (VAT), (ii) nor does it alter the allocation of transfer and similar taxes under Clause 19 (Costs and Expenses). 7.9 Clause 6.1.6 (Exclusion of Claims and Remedies) and 6.6 (Liability Cap) applies to any Tax Claims under this Clause 7 and Clauses 6.1.4 (duty to mitigate losses and damages), 6.2 (Notice of Breach), 6.4 (Suspension), and 6.9 (Third Party Claims) shall apply mutatis mutandis to any Tax Claims under this Clause 7. 7.10 Cooperation in Tax issues 7.10.1 The Purchaser undertakes to procure that the Target Company prepares and timely files all Tax Returns for all periods prior to Closing, other than the Tax Returns for

28/47 31.03.2025 (31 March, 2025), and the Purchaser undertakes to procure that Target Company (each at the Seller's own cost): (i) permits the Seller to review and comment, within reasonable time, on each such Tax Return prior to it being filed; (ii) implements changes to such Tax Returns as the Seller may reasonably request in writing provided such changes are in line with, and permitted by, applicable law and jurisprudence; and (iii) to the extent permitted by law, prepares such Tax Returns consistent with past practice applied by the Target Company as the Seller may reasonably request in writing. 7.10.2 The Parties shall cooperate (and the Purchaser shall procure that the Target Company cooperates with the Seller) in good faith and to the extent reasonably requested by the other Party, in connection with the filing of Tax Returns for periods beginning prior to or until the Closing Date. Such cooperation shall include the retention and (upon Seller's request) the provision of records and information which are or may be relevant to any such filing as well as in relation to compliance with Pillar 2 Taxes matters for any accounting period ending on or before Closing Date and any accounting period commencing on or before Closing Date but ending after Closing Date in so far as such period relates to the Seller’s ownership of the Target Company, and the preparation and filing of any Pillar 2 Taxes documents taking into account applicable law and Tax Authority practice and guidance and the respective policies and practices of the Target Company before and after Closing Date. 7.10.3 Whenever any Tax Authority announces or commences a Tax audit or any other Tax or levy inspection or a joint audit of wage-dependent levies and/or asserts a claim, makes an assessment or an inspection, issues a request for supplemental information or otherwise disputes the amount of declared or self-calculated Tax for which the Seller is or may be liable under this Agreement, the Purchaser shall, if informed of such assertion, timely inform the Seller, and the Seller, at its own cost, shall have the right to control, decide on and carry out independently any resulting proceedings in all instances and to determine whether and when to settle any additional claims of the Tax Authority (if and to the extent such proceedings or determinations affect the amount of Tax for which the Seller may be liable), and whether and when ordinary or extraordinary remedies against decrees or decisions of the Tax Authority shall be taken. In particular, the Seller shall have the right to attend all meetings of a Tax audit with the Tax Authority. 7.10.4 Whether or not the proceedings are controlled by the Purchaser or the Seller, copies of any formal minutes, reports, decrees and decisions initiating the proceeding of the Tax Authority in connection with such proceedings shall be delivered to the Seller

29/47 always provided and to the extent it concerns a matter that could potentially give rise to a Tax Claim. 7.10.5 Without prejudice to liabilities allocated in Sections 6 and 7, in the case that the Austrian VAT Group, including the Target Company, is challenged by a Tax Authority and any company of the VAT Group has to pay VAT on any intra-group services and/or deliveries, then (i) the companies of the VAT Group concerned will issue respective invoices to each other, as the case may be, and (ii) will settle or pay the respective VAT to each other, as the case may be. 7.11 GAAP Accounts 7.11.1 The Purchaser shall cooperate with the Seller to prepare and submit a balance sheet (Bilanz) and related profit and loss account (Gewinn- und Verlustrechnung) of the Target Company according to Austrian GAAP (UGB) and the tax balance sheet (Steuerbilanz) as per the Closing Date ("GAAP Accounts") in a timely manner for the Tax Returns. 7.11.2 The GAAP Accounts shall solely serve the purpose of allocating taxable partnership income from the Target Company to the Seller (up to and including Closing Date) and the Purchaser (as from Closing Date) and determining and reporting Seller's taxable income derived from the Target Company (including Seller’s capital gain crystallizing upon the sale of the Share) pursuant to, and in line with, Legal Provisions (including, but not limited to, Section 188 BAO) and shall not be used to calculate the Purchase Price and shall be disregarded when calculating the Purchase Price. Further, the GAAP Accounts may not lead to (i) any direct or indirect claim (whatsoever nature, in particular not under Clauses 5, 7, 8 or 9) from the Purchaser against the Seller (or its Affiliates) or (ii) a direct or indirect reduction or increase of the Purchase Price (in particular according to Clause 4). 7.11.3 The Parties shall cooperate in good faith in connection with the preparation and determination of the GAAP Accounts and the Parties shall provide each other, on reasonable advance notice and during normal business hours, with any information and documents, and access to the relevant employees of the other Party (or the Target Company) as each Party may reasonably request to prepare or review (as applicable) the GAAP Accounts. 8. Customer Warranty Claims Indemnity 8.1 At the Purchaser’s request, the Seller shall indemnify and hold harmless the Target Company from and against any Loss incurred by the Target Company to the extent resulting from warranty claims (Gewährleistungsansprüche) made by customers of the Target Company (i) other than Affiliates of the Purchaser (i.e., Kadant Inc. and its Affiliates); (ii) relating to any of the products listed in Exhibit 8.1 stating inter alia the respective product numbers ("Selected Products") provided the respective

30/47 Selected Products have been manufactured and sold to the respective costumer prior to the Closing Date; (iii) until the end of the respective warranty period for the respective Selected Product as agreed between the customer and the Target Company (however, subject to the Customer Warranty Claim Indemnification Period); and (iv) claiming the non-conformity of the respective Selected Products provided such non-conformity is described in the column "Abweichungsbeschreibung" (description of non-conformity) of Exhibit 8.1 ("Customer Warranty Claim"), if and to the extent that no reserve or provision has been made for such Customer Warranty Claim in the Closing Date Accounts.

Such books and records and such copies shall only be used (i) to

42/47 monitor compliance with the terms of the Agreement, (ii) in connection with or in preparation of any audits or filings (e.g., tax or customs), (iii) to comply with any Legal Provisions, regulations or professional standards or (iv) to the extent required to fulfill the obligations under this Agreement. 16.5 Any reference to the Target Company in this Clause 16 shall for the purposes of this Clause 16 also refer to voestalpine ▇▇▇▇▇▇ Profil GmbH. 17. Non-competition 17.1 To protect the goodwill of the Target Company, Seller covenants with Purchaser that, from the Closing Date and for a period of three years thereafter (the “Restricted Period”), Seller and its Affiliates (meaning solely, for the purpose of this Clause 17, direct or indirect subsidiaries controlled by Seller as of the Closing Date) shall not, whether for compensation or without compensation, directly or indirectly, engage in activities primarily directed at competing with the Business of the Target Company in the geographic markets in which the Target Company actively conducts the Business as of the Closing Date (“Competitor”). For clarity and without limiting the foregoing, the following shall not constitute a breach of this Clause: (i) Passive investments by Seller or its Affiliates of up to 5% of any class of securities of any company, whether or not such company is a Competitor. (ii) The continuation of Seller’s or its Affiliates’ existing business activities as of the Signing Date, provided that any trading activities overlapping with the Business remain only a minor part thereof. (iii) Provision of general services, advisory services, or products to third parties (including Competitors), provided such provision of services, advisory services or products is not specifically intended to support a Competitor’s direct competition with the Target Company. (iv) M&A activities, provided that any potential target is only to a minor extent engaged in activities that compete with the Business. (v) Nothing in this Section shall prevent Seller or its Affiliates from trading, offering, or developing their own business in the form and scope in which it exists at the Signing Date. 17.2 During the Restricted Period, Seller shall not, and shall cause its Affiliates not to, directly solicit the key employees listed in Exhibit 17.2.This restriction shall not apply to: (i) unsolicited approaches initiated by the employee; (ii) general or public job postings; (iii) recruiter outreach not specifically targeting these individuals. 17.3 The Parties acknowledge that the duration of the Restricted Period is necessary because the Seller holds materially relevant know how and confidential information

43/47 relating to the Business, the use of which in competition would significantly disadvantage the Target Company. A three year period is therefore reasonable and appropriate to protect the Purchaser’s legitimate interests and the acquired goodwill. 17.4 Notwithstanding the general rule in Clause 22.9, if any provision of this Clause 17 is held to be void, invalid or unenforceable, such provision shall be ineffective only to the extent of such voidness, invalidity or unenforceability, and only with respect to this Clause 17. The remainder of this Clause 17 shall remain valid and enforceable. The validity of the remaining provisions of this Agreement shall not be affected thereby. 18. Confidentiality 18.1 No Party shall make any press release or similar public announcement with respect to this Agreement or the transaction contemplated hereby other than the press releases and announcements mutually agreed between the Parties in advance of Signing and attached hereto (in the agreed form) as Exhibit 18.1. 18.2 After the dissemination of such press releases, the Parties shall treat as strictly confidential and not disclose or use any information received or obtained as a result of entering into this Agreement which relates to (i) the existence and/or provisions of this Agreement; or (ii) the negotiations relating to this Agreement, unless (a) the disclosure or use is required by law, any regulatory body or any recognized stock exchange on which the shares of any Party or an Affiliate of such Party are listed; or (b) the disclosure or use is required to vest the full benefit of this Agreement or of any other agreement entered into in connection with this Agreement by any Party; or (c) the disclosure or use is required for the purpose of any judicial proceedings arising out of this Agreement or any other agreement entered into under or pursuant to this Agreement or the disclosure is made to a Tax authority in connection with the Tax affairs of the disclosing Party; or (d) the disclosure is made to professional advisers of any Party on terms that such professional advisers undertake to comply with the provisions of this Clause 18.2 in respect of such information as if they were a party to this Agreement; or (e) the other Party has given prior written consent to the disclosure or use. 19. Costs and Expenses 19.1 Each Party shall be responsible for and bear its own costs and expenses incurred in connection with the preparation, conclusion and consummation of this Agreement and the transactions contemplated thereby, including without limitation the costs and expenses of its advisors, in particular attorneys' fees, auditors' fees, as well as fees of financial advisors, if any. 19.2 All costs, duties, transfer taxes and fees resulting from or in connection with the execution of this Agreement (including its Exhibits), including, but not limited to real estate transfer tax (RETT), registration fee and notarial fees (excluding (if applicable) fees for the storage of the USB), the costs in connection with obtaining the FDI and

44/47 the permit under the Lower Austrian Land Transfer Act (NÖ Grundverkehrsgesetz) shall be borne by the Purchaser, except for any cost for counsel of the Seller. 20.

Any waiver to this effect must be explicitly in writing. 22.9 If any provision of this Agreement is held to be illegal, invalid or unenforceable, in whole or in part, such provision or part shall to that extent be deemed not to form a part of this Agreement but the legality, validity or enforceability of the remainder of this Agreement shall not be affected.
