REPORT ON REVIEW OF INTERIM CONDENSED CONSOLIDATED FINANCIAL INFORMATION

To the Shareholders and Management of

StoneCo Ltd

Introduction

We have reviewed the accompanying interim condensed consolidated financial statements of StoneCo Ltd (the “Company”) as at June 30, 2023 which comprise the interim consolidated statement of financial position as at June 30, 2023 and the related interim consolidated statements of profit or loss and of other comprehensive income for the three and six-month periods then ended, and of changes in equity and cash flows for the six-month period then ended and explanatory notes.

Management is responsible for the preparation and presentation of this interim consolidated financial information in accordance with IAS 34 – Interim Financial Reporting, issued by the International Accounting Standards Board (IASB). Our responsibility is to express a conclusion on this interim consolidated financial information based on our review.

Scope of review

We conducted our review in accordance with International Standard on Review Engagements 2410 - Review of Interim Financial Information Performed by the Independent Auditor of the Entity. A review of interim financial 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 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 interim condensed consolidated financial statements are not prepared, in all material respects, in accordance with IAS 34 – Interim Financial Reporting, issued by the International Accounting Standards Board (IASB).

The accompanying notes are an integral part of these unaudited interim condensed consolidated financial statements.

StoneCo Ltd. (the “Company”), is a Cayman Islands exempted company with limited liability, incorporated on March 11, 2014. The registered office of the Company is located at 4th Floor, Harbour Place 103 South Church Street, P.O. box 10240 Grand Cayman E9 KY1-1002.

On November 29, 2022, the Company announced that the Brazilian Central Bank (“BACEN”) has approved the technical requirement of change of control submitted by the Company amid a corporate restructuring involving the conversion of Eduardo Pontes interests in Company´s Class B super-voting shares from HR Holdings, LLC (which were held indirectly through holding companies) into Class A shares directly owned by his family vehicles ("Corporate Restructuring”).

As a result of the Corporate Restructuring, there was a decrease in the concentration of votes held by the Company’s founding shareholders and HR Holdings, LLC became the owner of 31% of the Company’s voting power, whose ultimate parent is an investment fund, the VCK Investment Fund Limited SAC A, owned by the co-founder of the Company, Andre Street.

The Company’s shares are publicly traded on Nasdaq (under the ticker STNE) and depositary receipts “BDRs” representing the Company’s shares are traded on the São Paulo exchange B3 (under the ticker STOC31).

The Company and its subsidiaries (collectively, the “Group”) provide financial services and software solutions to clients across in-store, mobile and online devices helping them to better manage their businesses, become more productive and sell more - both online and offline.

The interim condensed consolidated financial statements of the Group for the six months ended June 30, 2023 and 2022 were approved by the Audit Committee on August 11, 2023.

1.1. Seasonality of operations

The Group’s revenues are subject to seasonal fluctuations as a result of consumer spending patterns. Historically, revenues have been strongest during the last quarter of the year as a result of higher sales during the Brazilian holiday season. This is due to the increase in the number and amount of electronic payment transactions related to seasonal retail events. Adverse events that occur during these months could have a disproportionate effect on the results of operations for the entire fiscal year. As a result of seasonal fluctuations caused by these and other factors, results for an interim period may not be indicative of those expected for the full fiscal year.

The interim condensed consolidated financial statements for the six months ended June 30, 2023 have been prepared in accordance with IAS 34 – Interim Financial Reporting, issued by the International Accounting Standards Board (“IASB”).

The interim condensed consolidated financial statements are presented in Brazilian Reais (“R$”), and all values are rounded to the nearest thousand (R$ 000), except when otherwise indicated.

The interim condensed consolidated financial statements do not include all the information and disclosures required in the annual financial statements and should be read in conjunction with the Group’s annual consolidated financial statements as of December 31, 2022.

The accounting policies adopted in this interim reporting period are consistent with those of the previous financial year.

The preparation of the Group’s financial statements requires management to make judgments and estimates and to adopt assumptions that affect the amounts presented referring to revenues, expenses, assets and liabilities at the financial statement date. Actual results may differ from these estimates.

The judgements, estimates and assumptions are frequently revised, and any effects are recognized in the revision period and in any future affected periods. The objective of these revisions is mitigating the risk of material differences between the estimated and actual results in the future.

In preparing these interim condensed consolidated financial statements, the significant judgements and estimates made by management in applying the Group’s accounting policies and the key sources of estimation uncertainty were the same as those that are set the consolidated financial statements for the year ended December 31, 2022, with no changes except for updates described in Note 11.1.

In accordance with IFRS 10 - Consolidated Financial Statements, subsidiaries are all entities in which StoneCo Ltd. holds control.

The following table shows the main consolidated entities, which correspond to the Group’s most relevant operating vehicles.

During the quarter we consummated a reorganization of the businesses carried out by our former subsidiary Cappta S.A. As a result of the reorganization, we no longer have an interest in the activities of providing technology solutions for payments in installments and we increased to 100% our interest in the technology solutions for electronic transfers. Both activities were up to June 30, 2023, carried out by Cappta of which we owned 59.6%. As a result of the transaction, we no longer have an investment in Cappta and we have a 100% interest in Stef S.A. The transaction did not have any material impact on our financial statements.

During the six months ended June 30, 2023 there were no other corporate reorganizations that changes the interests held by the Company in its subsidiaries.

The Group holds call options to acquire additional interests in some of its subsidiaries (Note 5.6) and issued put options to non-controlling investors (Note 5.9).

The Group holds call options to acquire additional interests in some of its associates (Note 5.6.).

Comprised of Banco Inter S.A. (“Banco Inter”)´s shares, acquired on June, 2021. During the first quarter of 2023, the Group sold its remaining stake in Banco Inter, representing 16.8 million shares. The shares were sold at a price of R$ 12.96, equivalent to R$ 218,105. The change in fair value of equity securities at FVPL for the six months ended June 30, 2023 was a gain of R$ 30,574 (for the six months ended June 30, 2022 was a loss of R$ 850,079), which was recognized in the statement of profit or loss.

Short and Long-term investments are denominated in Brazilian reais and U.S. dollars.

Accounts receivable are amounts due from card issuers and acquirers regarding the transactions of clients with card holders, performed in the ordinary course of business.

Part of the cash needs by the Group to advance payments to acquiring customers are met by the definitive sale of receivables to third parties. When such sale of receivables is carried out to entities in which we have subordinated shares or quotas, the receivables sold remain in our balance sheet, as these entities are consolidated in our financial statements. As of June 30, 2023 a total of R$ 325,420 are consolidated through Fundo de Investimento em Direitos Creditórios - Bancos Emissores de Cartão de Crédito - Stone III (“FIDC AR III”), of which the Group has subordinated shares (December 31, 2022 - R$ 1,116,264). When the sale of receivables is carried out to entities we do not control and in transactions where we do not have continuous involvement, the amounts transferred are derecognized from the accounts receivable from card issuers. As of June 30, 2023, the sale of receivables that were derecognized from accounts receivables from card issuers in our balance sheet represent the main form of funding used by the Group to fund our prepayment business.

Accounts receivable held by FIDCs guarantee the obligations to FIDC quota holders.

Accounts payable to clients represent amounts due to accredited clients related to credit and debit card transactions, net of interchange fees retained by card issuers and assessment fees paid to payment scheme networks as well as the Group’s net merchant discount rate fees which are collected by the Group as an agent.

Trade accounts receivables are amounts due from clients mainly related to subscription services and equipment rental.

As required by the BACEN regulation, the financial assets arising from banking solutions must be deposited in accounts custody by the BACEN or invested in Brazilian National Treasury Bonds, in order to guarantee the deposits from banking customers.

In June 30, 2023, the balances in transit were R$ 86,573 (December 31, 2022 - R$ 243,782).

In the ordinary course of the business, the Group funds its prepayment business through a mix of own cash, debt and receivables sales.

In August 2020, the first series of FIDC AR III senior quotas was issued, with an amount of up to R$ 2,500,000, and maturity in August 2023. They were issued for 36 months, with a grace period of 15 months to repay the principal amount. During the grace period, the payment of interest is made every three months. After this period, the amortization of the principal and the payment of interest is every three months. The benchmark return rate is CDI + 1.5% per year.

Payments of R$ 625,000 refers to the amortization of the principal and R$ 56,441 refer to the payment of interest of the first series of FIDC AR III.

In March 2021, the Group negotiated an amendment of the contract to postpone the payment date of the principal to March 2022 and the benchmark return rate became 100% of the CDI + 1.50% per year.

In February 2022, the Group negotiated an amendment of the contract to postpone the payment date of the principal to March 2023 and the benchmark return rate became 100% of the CDI + 1.80% per year. The mezzanine quotas were settled on March 2, 2023.

The Group has lease contracts for various items of offices, vehicles and software in its operations. The Group’s obligations under its leases are secured by the lessor’s title to the leased assets. Generally, the Group is restricted from assigning and subleasing the leased assets.

Bonds were issued in 2021, raising USD 500 million in 7-year notes with a final yield of 3.95%. The total issuance was R$ 2,510,350 (R$ 2,477,408 net of the offering transaction costs, which will be amortized over the course of the debt). The Group has entered into a hedge to protect its currency risk, see Note 5.6.1.

The Group issued CCBs (bilateral unsecured term loans), with multiple counterparties and maturities up to 12 months. The principal and the interests of this type of loan are mainly paid at maturity. The proceeds of these loans were used mainly for the advance payments to acquiring customers.

During 2021, the Group entered into hedge operations to protect its inaugural dollar bonds (Note 5.5.2.4), subject to foreign exchange exposure using cross-currency interest rate swap contracts. Additionally, in May 2023, the Group entered into hedge operations to protect bank borrowings (Note 5.5.2.5.), subject to foreign exchange exposure using cross-currency interest rate swap contracts. The transactions have been designated for hedge accounting and classified as cash flow hedge of the variability of the designated cash flows of the dollar denominated bonds / bank borrowings due to changes in the exchange rate. The effective portion of the derivative's gain or loss is initially reported as a component of accumulated other comprehensive income, recorded in a specific equity account, and subsequently reclassified into earnings in the same period the hedge object affects earnings, while any ineffective portion, when applicable, is immediately recognized in profit or loss. The details of the cross-currency swaps and their financial position as of June 30, 2023, are presented as follows.

Additionally, in 2023 the Group paid R$ 155,072, on coupon payments of the cross-currency swaps described above.

The Group is party to non-deliverable forward (“NDF”) contracts with different counterparties approved by the Board of Directors following the Counterparty Policy to hedge its foreign currency risk in U.S. Dollar and Euro. As of June 30, 2023, the Group hedged the notional of US$ 8,171 thousand using NDF contracts with rates between 4.7698 and 5.0492 of Brazilian Reais per each 1.00 U.S. Dollar, and the notional of € 570 thousand using NDF contracts with rates between 5.3040 and 5.4718 of Brazilian Reais per each 1.00 Euro. The maturity of the operations is up to August 2023. In the six months ended June 30, 2023, the amount related to these derivatives recognized in the statement of profit or loss was a gain of R$ 19,212 (gain of R$ 14,631 in the six months ended June 30, 2022).

The Group mitigates the interest rate risk generated by the gap between its prepayments of receivables (fixed rate) and its funding activities (either fixed or floating) with mixed maturities. This hedge is executed over-the-counter ("OTC") with multiple financial institutions following its Counterparty Policy. The contracted annual rate is between 11.3% and 14.3%. The notional of the operations is R$ 5,586 thousand and its maturities are up to December 2024. In the six months ended June 30, 2023, the amount related to these derivatives recognized in the statement of profit or loss was an expense of R$ 11,795 (expense of R$ 2,625 in the six months ended June 30, 2022).

The Group’s activities expose it to market, liquidity, credit, and counterparty risks. The two main market risks for the Group are interest rates and exchange rates. Interest rate risk arises from the fact the Group’s originates assets at fixed rates (credit card prepayment and loans) and funds itself both at fixed and floating rates with unmatched maturities of such assets. The second one is generated by the exchange rates among Brazilian Reais and the currencies of countries where the Groups has subsidiaries in addition to its indebtedness and expenses denominated in other currencies rather than BRL. The Group main liquidity risk is its inability to raise financing to continue its prepayment business, which although is not a legal obligation, is a relevant part of its revenues. has two. The counterparty risk is mainly generated by the counterparties that the Group engage with into financial contracts for hedging, investments and committed funding, in addition to its inherent credit risk exposure to credit card issuers.

The Board of Directors has approved policies and limits for its financial risk management. The Group uses financial derivatives only to mitigate market risk exposures. It is the Group’s policy not to engage in derivatives for speculative purposes. Different levels of managerial approval are required for entering into financial instruments depending on its nature and the type of risk associated.

Financial risk management is carried out by the global treasury department (“Global Treasury”) at the Group level. Global treasury identifies, evaluates, and hedges financial risks in close co-operation with the Group’s operating units.

The following table shows an analysis of financial instruments recorded at fair value by level of the fair value hierarchy:

As of June 30, 2023, there were no transfers between the fair value measurements of Level I and Level II and between the fair value measurements of Level II and Level III.

The table below presents a comparison by class between book value and fair value of the financial instruments of the Group, other than those with carrying amounts that are reasonable approximations of fair values:

StoneCo Ltd. is domiciled in Cayman and there is no income tax in that jurisdiction. The income earned by StoneCo Ltd. from its operations abroad can be subject to income tax at the main rate of 15%.

Considering the fact that StoneCo Ltd. is an entity located in Cayman which has no Income Tax, for the purpose of the following reconciliation of income tax expense to profit (loss) for the periods ended June 30, 2023 and 2022, it was applied the combined Brazilian statutory rates at 34%.

In Brazil such combined rate is applied, in general, to all entities and comprises the Corporate Income Tax (“IRPJ”) and the Social Contribution on Net Income (“CSLL”) on the taxable income of each Brazilian legal entity (not on a consolidated basis).

The Group has accumulated tax loss carryforwards and other temporary differences in some subsidiaries in the amount of R$ 151,866 (December 31, 2022 – R$ 144,529) for which a deferred tax asset was not recognized and are available indefinitely for offsetting against future taxable profits of the companies in which the losses arose. Deferred tax assets have not been recognized with respect of these losses as they cannot be used to offset taxable profits between subsidiaries of the Group, and there is no other evidence of recoverability in the near future.
