4.4. Describe any judicial, administrative or arbitration proceedings to which the issuer or its controlled companies are a party, specifying labor, tax, civil, environmental and other cases: (i) that are not confidential, and (ii) that are material for the business of the issuer or its controlled companies, stating: a. court b. jurisdiction c. filing date d. parties to the proceedings e. amounts, assets or rights involved f. main facts g. summary of decisions on the merits issued h. case status i. if the chance of loss is: i. probable ii. possible iii. remote j. reason why this case is deemed material k. analysis of the impact in the event of an unfavorable decision For purposes of this item, we adopted as a materiality criterion operations involving amounts higher than R$1,124 million, which accounts for 0.5% of Itaú Unibanco Holding's Equity under IFRS as of September 30, 2025. Civil, tax and labor contingencies are the subject-matter of a provision whenever loss is assessed as probable. Provisions are also recognized, irrespective of the event of an unfavorable outcome to the company, for tax contingencies in which the outcome of the case depends on the recognition of unconstitutionality of legislation in force. Management believes that the provisions for judicial and administrative contingencies recognized are sufficient to cover probable losses that may be reasonably estimated. We believe that any losses arising from other administrative or judicial contingencies will have no adverse material effect on our business, financial position or results of operations. Civil Proceedings Case No. 0003056-02.2003.8.26.0200 a. Court: 2nd Civil Lower Court of Itapira (State of São Paulo). b. Jurisdiction: Superior Court of Justice (STJ) c. Filing date:08.06.2003 d.

f. Main facts: This is a lawsuit to review current account, loan and renegotiation agreements, in which the bank was ordered, by a final and unappealable decision (December 12, 2007), to exclude interest capitalization and refund overpaid amounts, adjusted to include interest in the same proportion as it had been charged by the bank. Upon calculation of the liquid amount, the lower court, based on the capitalized interest criterion and with 2,400.64% of compensatory interest incurred from 2003 to 2007, approved the amount of approximately R$7.6 billion to be refunded to the plaintiff (May 21, 2018). The Appellate Court of the State of São Paulo (TJSP) overturned this judgment to exclude capitalization and charge simple interest as of the date of summons (2003), reducing the award amount to approximately R$3.5 million (May 2, 2019). Itaú made a judicial deposit of the adjusted awards amount (R$5.9 million in August 2019). Plaintiff filed a motion for clarification, which was denied (November 4, 2019). Plaintiff and former lawyer filed special appeals, which were granted by the TJSP (April 20, 2021) and the case is to be held by the judge under advisement at the Superior Court of Justice (STJ). g. Summary of decisions on the merits issued: The decision issued at the cognizance phase, which is final and unappealable, has ruled that the bank review the contracts and exclude the capitalization amount, as well as refund twice the overstated amounts charged, adjusted to include interest earned at the same rates charged by the bank. Upon calculation of the liquid amount, a decision was issued approving the expert evidence in the amount of R$7.6 billion, with the following assumptions: capitalized interest and 2,400.64% of compensation interest from 2003 to 2007. The Appellate Court partially overruled this decision, reducing the amount in dispute to R$3.5 million by excluding capitalization and determining the inclusion of simple interest from the date of summons. h. Case status: The special appeals filed by the Plaintiff and former lawyer before the STJ against the appellate decision issued by the TJSP on April 22, 2019 are pending trial. i. Chance of loss: Remote. j. Reason why this case is deemed material: Amount in dispute. k. Analysis of the impact in the event of an unfavorable decision: In August 2019, the bank paid the award in effect in the amount of R$5.9 million. The remaining remote risk of loss is R$13.8 billion. Cases No. 0012488-09.2002.8.14.0301 and No. 0035211-78.2002.8.14.0301 a. Court: 5th Civil Lower Court of Belém (State of Pará). b. Jurisdiction: Appellate Court of the State of Pará (TJPA) c. Filing date: 03.18.2002 and 10.14.2002 d. Parties to the proceedings: Rondhevea Administração e Participações Ltda. vs. Itaú Unibanco S.A. and Itaú Corretora de Valores Mobiliários e Câmbio. e. Amounts, assets or rights involved: R$7,727,062,162.90 (September/2025). f. Main facts: Itaú is a defendant in two lawsuits filed by Mr. Antonio Cabral (later succeeded by Rondhvea Adm. e Participações). Itaú allegedly would have sold 6,360 shares issued by Itaú and 5,000 shares issued by Banco União Comercial (succeeded by Itaú) in 1985, without the plaintiff's authorization. In a final and unappealable decision, Itaú was ordered to award the plaintiff an amount corresponding to the share value and respective accessory obligations. Upon calculating the number of shares, under calculation of the liquid amount, the expert

![](referenceform-iuhv10sec006.jpg)

appraiser disregarded the reverse split of shares as set forth by CVM Instruction No. 56/87, which took place in March 1987, at 1,000 for 1 share, and thus determined the amount of R$4 billion (expert opinion of August 30, 2017). These expert opinions were approved by the lower court judge (September 18, 2020), thus prompting Itaú to file the proper appeals, which were both granted with suspensive effect. One of the bank's appeals has already been adjudicated and granted, annulling the homologation decision due to lack of reasoning; a new judgment at the first instance is pending. The other appeal is still pending trial. Itaú had also filed complaints with the Disciplinary Board of Courts and the National Justice Board (CNJ), which were dismissed as the judge in charge had passed away. Itaú made a judicial deposit of the amount it understands as effectively due, which corresponds to the price of shares and accessory obligations based on the reverse split carried out in March 1987 (R$895,004.60 – October 2020). g. Summary of decisions on the merits issued: At the cognizance phase, the bank was ordered to pay plaintiff the amount corresponding to the shares sold without evidence of plaintiff's authorization, as well as corresponding earnings. Upon calculation of the liquid amount, the lower court judge approved the expert witness report (September 18, 2020), and stated, in both lawsuits, that the bank owed about R$4 billion. An appellate decision has already been handed down in one of the lawsuits, granting the appeal filed by the bank to annul the judgment of ratification due to lack of statement of reasons (ruling on May 15, 2023). h. Case status: In one of the cases, the motion for clarification was tried in February 2025 and the records are awaiting new decision in respect to liquidation issued at the lower court level. In the other, the appeal filed by the bank is pending trial by the TJPA. i. Chance of loss: Remote j. Reason why this case is deemed material: Amount in dispute. k. Analysis of the impact in the event of an unfavorable decision: Pay award corresponding to the value of shares and respective accessory obligations. Tax Claims Case No.16327.720661/2021-45 a. Court: Administrative appellate court - Administrative Board of Tax Appeals (CARF). b. Jurisdiction: Administrative appellate court (CARF). c. Filing date: 09.22.2021 d. Parties to the proceedings: Federal Government (National Treasury) vs. Banco Itaucard S.A. e. Amounts, assets or rights involved: R$1,231,917,544.38 (September/2025). f. Main facts: On September 22, 2021, a tax assessment notice was received aimed at the collection of social contribution (CSLL) on the grounds of alleged lack of addition, in Part A of LACS book, of debit balances related to counterparts of surplus and deficit of depreciation in 2017, as tax authorities consider them nondeductible. This assessment notice was upheld by the Federal Revenue Service Judgment Office (DRJ) at the trial of the objection filed, and a voluntary appeal was filed. O This voluntary appeal started to be tried at CARF, where, instead of entering judgment, the judge ordered the production of more evidence.

------

![](referenceform-iuhv10sec007.jpg)

g. Summary of decisions on the merits issued: DRJ justified its decision on the grounds that the adjustments arising from surplus and deficit of depreciation cause no tax effects on CSLL, and should be neutralized off books by excluding or adding any corresponding revenues or expenses in the calculation of the contribution calculation basis. h. Case status: Appellate decision by DRJ: 09.23.2022; Voluntary Appeal filed before CARF is pending trial. i. Chance of loss: Possible. j. Reason why this case is deemed material: Amount in dispute. k. Analysis of the impact in the event of an unfavorable decision: In the event of an unfavorable outcome at administrative level, the case will be taken to the judicial courts, with possible pledge of guarantee required. Case No. 16327.721240/2019-17 a. Court: Administrative Board of Tax Appeals (CARF). b. Jurisdiction: Administrative appellate court (CARF). c. Filing date: 12.30.2019 d. Parties to the proceedings: Federal Government (National Treasury) vs. Banco Itaucard S.A. e. Amounts, assets or rights involved: R$1,527,876,792.80 (September/2025). f. Main facts: Tax assessment notices levied aimed at the collection of PIS/Cofins on the grounds of alleged failure to submit for taxation the economic-financial result of leasing operations carried out, with a 150% fine levied. Lawsuit attached to Case No. 16327.721239/2019-92 about the same subject matter challenged. On May 25, 2020, the administrative lower court handed down a ruling to uphold the tax assessment, with the company thus filing a voluntary appeal. The voluntary appeal started to be tried at CARF, where, instead of entering judgment, the judge ordered the production of more evidence. g. Summary of decisions on the merits issued: DRJ stated the reasons for upholding the tax assessment notice on the grounds that, during the contract term, the Bank accurately calculated the PIS/COFINS basis but had unduly reversed the depreciation surplus amounts at the end of each contract. h. Case status: Appellate decision by DRJ: 05.25.2020; Voluntary Appeal filed before CARF is pending trial. i. Chance of loss: Possible (R$168,527,410.14) and Remote (R$1,359,349,382.66). j. Reason why this case is deemed material: Amount in dispute.

k. Analysis of the impact in the event of an unfavorable decision: In the event of an unfavorable outcome at administrative level, the case will be taken to the judicial courts, with possible pledge of guarantee required. Case No. 16327.720188/2019-81 a. Court: Administrative Board of Tax Appeals (CARF). b. Jurisdiction: Administrative appellate court (CARF). c. Filing date: 02.27.2019 d. Parties to the proceedings: Federal Government (National Treasury) vs. Itaú Unibanco S.A. e. Amounts, assets or rights involved: R$1.561.558.885,86 (September/2025). f. Main facts: Tax assessment notice levied aimed at the collection of social security tax due on payments of employee and management profit sharing, meal voucher and food allowance paid in tickets and hiring bonus in 2014 On February 11, 2021, the administrative lower court handed down a ruling to partially uphold the tax assessment, with the company thus filing a voluntary appeal. On November 7, 2023, CARF ruled to grant the voluntary appeal to fully cancel the tax assessment. The Office of the General Counsel to the National Treasury (PGFN) filed a motion for clarification, which was granted but had no modificatory character, as it was handed down to merely correct clerical mistakes in the appellate decision document. A Special Appeal was filed by the PGFN, which is awaiting admissibility g. Summary of decisions on the merits issued: DRJ cancelled part of the tax assessment, which had been subject to review at the evidentiary remedy stage, during which an error in the assessed calculation was identified. With respect to the other cases presented by the defense, DRJ just upheld the tax assessment filed. Upon the trial of the Voluntary appeal filed, CARF ruled to cancel the tax assessment in full due to its groundlessness regarding the meal voucher and food allowance paid in tickets and hiring bonus, as well as to declare the tax assessment in connection with employee profit sharing null and void, in addition to dismissing the fine on assessment levied on debits on management profit sharing, considering that the amount due has been suspended at the judicial level. h. Case status: Appellate decision by DRJ: 02.11.2021; Appellate decision by CARF: 11.07.2023; Appellate decision by CARF on Motions for Clarification: 10.01.2024; Awaiting to be notified and a possible filing of a Special Appeal by the PGFN. i. Chance of loss: Possible (R$737,917,151.04) and Remote (R$823,641,734.82). j. Reason why this case is deemed material: Amount in dispute. k. Analysis of the impact in the event of an unfavorable decision: In the event of an unfavorable outcome at administrative level, the case will be taken to the judicial courts, with possible pledge of guarantee required.

The case is currently awaiting the potential filing of Internal Appeals by the parties. Internal Appeals were filed by the parties, pending judgment. g. Summary of decisions on the merits issued: Preliminary injunction and writ of mandamus were partially granted to dismiss the assessed portion calculated on a portion of profit sharing (the one meeting the legal frequency limits) which, therefore, is excluded from taxation. Furthermore, the part of the initial pleading intended to avert the entire original assessment (portion already paid, which we asked for refund only) was dismissed. The appellate decision on this appeal upheld the judgment, on the grounds that the defect of part of the profit sharing payments regarding the frequency does not apply to the entire profit sharing. h.

e. Amounts, assets or rights involved: In accordance with Law No. 12529/11, Article 37, item I, any violation of the economic order subjects the company to a fine ranging from one- tenth percent (0.1%) to twenty percent (20%) of the gross revenue of such company, group or conglomerate, earned in the last year prior to the filing of the administrative proceeding, in the business field in which the alleged violation was committed, which will never be lower than the alleged advantage gained whenever such calculation is possible. On the grounds of lack of definition of the calculation basis to be applicable, as well as the significant wide range of percentages applicable, it is not possible to estimate the fine amounts in the event of an unfavorable decision. f. Main facts: This is an administrative proceeding filed to investigate alleged cartel in the Brazilian onshore foreign exchange market involving the Brazilian currency (Brazilian real). These presumed antitrust conducts would have been engaged mainly in the FX spot and futures (derivatives) markets.

Parties to the proceedings: CADE ex officio vs. Itaú Unibanco S.A and Redecard S.A. e. Amounts, assets or rights involved: Not applicable. f. Main facts: In April 2019, the General Superintendency of CADE filed an administrative proceeding against Itaú Unibanco and Redecard to investigate an alleged antitrust practice in the credit card receivables market. Redecard had launched a program under which it would settle/clear credit card receivables in an account held at Itaú Unibanco in mere two days. CADE filed a preliminary injunction requesting the program to be suspended, which was dismissed as the program was upheld by virtue of a preliminary decision issued by the Federal Courts. In December 2019, Redecard decided to clear all bank accounts within two days, regardless of whether they were held at Itaú Unibanco, and as a result the lawsuit that upheld the program lost its purpose. Redecard and Itaú Unibanco filed their defenses, including legal and economic opinions, to evidence the inexistence of antitrust practices. The case was granted a favorable decision by the General Superintendency of CADE and the Department of Economic Studies, which understood there was no antitrust conduct in the case in question.

Three court members (José Levi, Charles Jaques, and Camila Alves) still need to vote. Members Diogo Thompson and Alexandre Cordeiro were disqualified from voting.

Case status: Currently pending at the CADE, with records to be seen by Member Camila Alves, who notified the Central Bank of Brazil as BACEN to provide information on the receivables market. In its response, the Central Bank has not provided significant information to the case. Member Camila Alves has set a ten-day period (counting from 4.7) for a statement to be expressed on Central Bank's response. Case may be included in the Appellate Court's agenda for a final decision to be rendered (if no other requests to see the records are made) by the end of the second half of 2025. i. Chance of loss: Possible. j. Reason why this case is deemed material: Image risk. k.

When the securities are debt-related, please indicate: i. Maturity, including early maturity conditions The maturity date of the Notes is April 15, 2031. If any of the following events occur (each one, an "Event of Default") and such occurrence survives time, the Trustee of the holders of the Notes, if so instructed by at least one-third (1/3) of the holders – computed at the face value of the Notes – or if so instructed by a special resolution of the holders of the Notes, will inform the Issuer of the accelerated maturity of the Notes, and the payment for which will become immediately enforceable, subject to the terms governing the calculation of the Early Redemption Amount.
