Tecnisa S.A. and Subsidiaries Quarterly Information (ITR) at September 30, 2025 and report on review of quarterly information Report on review of quarterly information

To the Board of Directors and Shareholders Tecnisa S.A.

Introduction

We have reviewed the accompanying individual parent company and consolidated interim accounting information of Tecnisa S.A. ("Company"), included in the Quarterly Information Form (ITR) for the quarter ended September 30, 2025, comprising the balance sheet at that date and the statements of income and comprehensive income for the quarter and nine-month period then ended, and the statements of changes in equity and cash flows for the nine-month period then ended, and explanatory notes.

Management is responsible for the preparation of the individual parent company and consolidated interim accounting information in accordance with the accounting standard CPC 21, Interim Financial Reporting, of the Brazilian Accounting Pronouncements Committee (CPC) and International Accounting Standard (IAS) 34, Interim Financial Reporting issued by the International Accounting Standards Board (IASB), as well as the presentation of this information in accordance with the standards applicable to Brazilian real estate development entities registered with the Brazilian Securities Commission (CVM), applicable to the preparation of the Quarterly Information (ITR). Our responsibility is to express a conclusion on this interim accounting information based on our review.

Scope of review

We conducted our review in accordance with Brazilian and International Standards on Reviews of Interim Financial Information (NBC TR 2410 - Review of Interim Financial Information Performed by the Independent Auditor of the Entity, and ISRE 2410 - Review of Interim Financial Information Performed by the Independent Auditor of the Entity, respectively). A review of interim information consists of making inquiries, primarily of persons responsible for financial and accounting matters, and applying analytical and other review procedures. A review is substantially less in scope than an audit conducted in accordance with Brazilian and International Standards on Auditing and consequently does not enable us to obtain assurance that we would become aware of all significant matters that might be identified in an audit. Accordingly, we do not express an audit opinion.

Conclusion

Based on our review, nothing has come to our attention that causes us to believe that the accompanying individual parent company and consolidated interim accounting information included in the quarterly information referred to above has not been prepared, in all material respects, in accordance with CPC 21 and IAS 34, presented in accordance with the standards issued by the CVM, applicable to Brazilian real estate development entities registered with CVM, applicable to the preparation of the Quarterly Information - ITR.

Emphasis of matter

As described in Note 2, the individual parent company and consolidated interim accounting information included in the Quarterly Information Form (ITR) has been prepared in accordance with the accounting standard CPC 21, and International Accounting Standard (IAS) 34, applicable to Brazilian real estate development entities, registered with the CVM. Accordingly, the accounting policy adopted by the Company for the recognition of revenue from the sale of real estate units under construction, as regards to timing of transfer of control, is in accordance with the guidance in CVM Circular Letter/CVM/SNC/SEP 02/2018 as to the application of Technical Pronouncement NBC TG 47 (IFRS 15). Our conclusion is not qualified in respect of this matter.

Statements of value added

The quarterly information referred to above includes the individual parent company and consolidated statements of value added for the nine-month period ended September 30, 2025. These statements are the responsibility of the Company's management and are presented as supplementary information under IAS 34. These statements have been subjected to review procedures performed together with the review of the interim accounting information for the purpose of concluding whether they are reconciled with the interim accounting information and accounting records, as applicable, and if their form and content are in accordance with the criteria defined in the accounting standard CPC 09 - "Statement of Value Added". Based on our review, nothing has come to our attention that causes us to believe that these statements of value added have not been properly prepared, in all material respects, in accordance with the criteria established in this accounting standard, and consistent with the parent company and consolidated interim accounting information taken as a whole.

Explanatory Notes

TECNISA S.A.

EXPLANATORY NOTES TO THE QUARTERLY INFORMATION - INDIVIDUAL AND CONSOLIDATED ITRs FOR THE NINE-

MONTH PERIOD ENDED SEPTEMBER 30, 2025

(Amounts expressed in thousands of Brazilian reais (R$), unless otherwise indicated)

  1. OPERATING CONTEXT

    Tecnisa S.A. ("Company") is a publicly held corporation headquartered at Avenida Nicolas Boer, 399, São Paulo

    - SP, Brazil, and listed on B3 S.A., in the Novo Mercado segment, under the ticker symbol TCSA3.

    The Company's corporate purpose and main operating activities are the incorporation, purchase, and sale of ready-built or off-plan residential and commercial properties, land, and ideal fractions, the construction of properties, and the provision of real estate consulting services. Its activities may be carried out independently or in conjunction with other entities, through participation in wholly owned subsidiaries, under shared control, or in affiliated companies.

    Since the Company's IPO in 2007, an important part of its business plan has focused on the development of the Jardim das Perdizes neighborhood. The first towers in the neighborhood were developed between 2013 and 2016 and, to continue with the launches, TECNISA had to wait for the auction of Additional Construction Potential Certificates ("CEPAC") under the Água Branca Consortium Urban Operation, which only took place in December 2023. At that time, Windsor Investimentos Imobiliários Ltda ("WINDSOR"), an SPE that develops Jardim das Perdizes and in which the Company held a 57.5% stake, acquired 206,152 CEPACs, sufficient for the construction of all the projects planned for the neighborhood according to feasibility studies. The acquisition required a disbursement of R$ 225 million, of which R$ 130 million related to TECNISA's stake in the project.

    While this strictly necessary move unlocked enormous value potential in TECNISA's main asset, it also increased its leverage levels. As a result, the Company has since sold some of its stake in the project, notably: R$ 50 million in the first quarter of 2024 and R$ 6.5 million in the first quarter of 2025, as disclosed on each occasion.

    The launches in Jardim das Perdizes that followed the acquisition of the CEPACs have shown sales performance in line with feasibility, with robust profit margins. However, the Company's projects outside Jardim das Perdizes have still seen margins squeezed by construction costs that have skyrocketed since the COVID-19 pandemic and could not be fully passed on in sales prices. In addition, some projects in the final stages of delivery faced

    Explanatory Notes

    labor shortage affecting the entire sector, leading to delays with implications for indirect costs and rework. Added to this, the worsening economic conditions, with the SELIC rate reaching 15% p.a., led to a significant increase in the cost of debt.

    This scenario caused the Company to exceed the financial covenants set forth in its debt agreements. It should be noted that the breaches were solely due to the exceeding of financial covenants and that the Company never failed to pay its debts, not even interest installments. The Company emphasizes that it has been successful in obtaining waivers from its creditors.

    The main banks offering real estatecredit have provided financing for all projects launched by the Company, signing the respective contracts under the Housing Finance System, i.e., using funds deposited in savings accounts, an increasingly scarce source of funding for which banks have been extremely strict in granting. This reinforces creditors' confidence in the Company's business conduct and solidity.

    FINANCIAL POSITION AND MANAGEMENT PLAN TO INCREASE LIQUIDITY (PARENT COMPANY)

    On September 30, 2025, the Company's (parent company) balance sheet shows an excess of current liabilities over current assets in the amount of R$412,099 (R$237,669 on December 31, 2024), substantially represented by loan and financing balances and related parties. In the consolidated balance sheet, current liabilities exceed current assets by R$75,068 (on December 31, 2024, current assets exceeded current liabilities by R$139,894).

    The Company's strategy to increase the parent company's liquidity is to sell units and complete construction projects that should contribute to cash generation, maximizing results and dividends. The Company has also been working intensively to reduce administrative expenses to keep them at levels appropriate to its operating context. Alternatives available for generating liquidity, if necessary, include the sale of receivables, the sale of land or project interests, as well as access to the financial and capital markets.

    An example of the search for liquidity alternatives was the negotiation for the sale of land in Jardim das Perdizes to CYRELA for R$ 510 million, as disclosed in a Material Fact on June 27, 2025 ("Transaction"). However, during the negotiations and discussion of specific details of the Transaction, situations arose that reduced the attractiveness of the proposal. As a result, on November 12, 2025, the Board of Directors decided to suspend negotiations, assessing that the loss in value resulting from the sale of the land under the conditions that were emerging at

    Explanatory Notes

    The operation would be much larger than the maintenance of the land and the cost of the debt.

    It is worth noting, as a subsequent event, a new fundraising of R$ 178 million through the issuance of debentures in December 2025, with a cost of CDI + 4.25% p.a. and final maturity in 2031, significantly extending the debt profile.

    The Company emphasizes that, after adjusting its debt, it will have a longer profile, with an average term of 3.0 years, compared to the current 1.5 years. On the other hand, regardless of the improvement in the debt profile and the relaxation of covenants, the Company may continue to evaluate proposals for the sale of assets under favorable conditions. It is also important to note that the recent deliveries of the Bosque Pitangueiras and Unik Residence developments, as well as the upcoming delivery of Reserva Figueiras, will contribute to cash generation in the coming quarters.
