“Staying away from the comfort zone” Managerial Report 2nd Quarter 2022

1 João Vitor Menin CEO INTER&Co "Stay away from the comfort zone". If there is a phrase that best describes our second quarter, this is certainly the one. Though always true at Inter, in this quarter it cannot be more illustrative given the milestones we achieved. We successfully concluded the listing of our shares in Nasdaq, becoming the first ever Brazilian company to upgrade its primary listing from Brazil to the US, thus paving the way for many others to follow. Consistent to our legacy, we again prioritized the interests of our minority shareholders by structuring the transaction with an in-the-money cash option, together with incorporating world-class governance practices, such as the inclusion of explicit tag along rights. True to our mission of simplifying people’s life, we launched our global account enabling our Brazilian domiciled clients to transact internationally in a simple and cost efficient manner. This product was very well received by our clients, which reached about 140 thousand global accounts by the end of June. From a financial perspective, I’m proud to say that we continue growing at disruptive pace. Our total gross revenues grew at an impressive pace of +130% relative to the same quarter of the prior year, reaching nearly R$1.5 bn. The quality of our revenues continue to improve meaningfully, being highly diversified across products and with stronger growth on asset-light fee revenue over interest income. Without putting our innovation capacity ever at risk, we continue being highly committed to delivering strong operational leverage. This quarter alone, our total gross revenues grew strongly while our expenses decreased, resulting in an improvement of 3 percentage points in our cost to income ratio. Last but not least, our main competitive advantage continues to be our people and culture. I’m convinced that we have a fully committed, capable and eager team to continue defying the limits of what’s possible by staying away from the comfort zone. We thank all shareholders, clients, employees for your continued support, and reiterate that the best is yet to come as we work together to build Inter's future.

MANAGERIAL REPORT | 2Q22 Average revenue per active client (ARPAC) and Cost to serve per active client (CTSAC) Our ARPAC increased this quarter from R$28 to R$32, representing a 16% increase. In parallel, our CTSAC decreased from R$14.4 to R$13.7, representing a 4.5% decrease. This combined effect is the direct result of our operational leverage initiatives, which are still at the early stages, given the still short average life of our clients in the platform. Average revenue per active client (ARPAC) + Cost to serve per active cliente (CTSAC) In R$ (monthly) Client acquisition cost In R$ annualized In 2Q22, the client acquisition cost reached R$ 32 per client, an increase of 17.9% in annual comparison. The increase is mainly due to higher issuing costs related to the supply chain disruptions on global chip factories. 6 Client acquisition cost (CAC) 14 1Q22 15 4Q21 31 19 3Q21 34 30 11 28 2Q21 14 2Q22 1Q21 12 32 34 ARPAC CTSAC 15 16 12 16 27 2Q21 2Q22 32 +17.9% Marketing Costs Operational costs

In the cohorts from 1Q18 to 2Q22 clients generate R$5 to R$15 of monthly revenue during the first few quarters as clients and reach an average of R$26 after 5 to 8 quarter as clients. The mature cohorts reach a monthly ARPAC around R$50. There is also an acceleration of our monetization as they consume our products at a faster pace, cohort by cohort. 2022-Q2 2018-Q1 Quarters of Relationship Avg. R$26 (cohorts 1Q18 to 2Q22)

MANAGERIAL REPORT | 2Q22 Funding In R$ Billion Funding Floating revenues grew 286% in 2Q22 in annual comparison and reached R$ 167 million. This growth can be explained by the increase in demand deposit balances and Selic rate. Floating revenue In R$ Million Pix 7.7% Market Share In 2Q22, we reached 357 million transactions done by Pix, 30% annual growth, reaching 7.7% of the transaction market share. There was transacted about R$ 118 billion through Inter over the second quarter. 9 2Q22 167 2Q21 43 +286% 2Q22 33% 17.7 38% 5% 24% 2Q21 1% 47% 6% 35% 1% 25.9 12% +46% Funding volume surpassed R$ 25.9 billion, an increase of 46% in annual comparison. Given the current rate environment, consumers are naturally allocating their excess liquidity in higher yielding funding. Inter’s day-to-day banking vertical continues performing strongly and has rapidly adapted to the new environment of higher interest rates. Floating revenue is calculated on a managerial basis by multiplying the balance of demand deposits (net of reserve requirements) times 100% of the CDI rate. Demand deposits Time deposits Savings deposits Securities issued Creditors by resources to release

Gross loan portfolio4 In R$ Billion Credit underwriting In R$ Billion The DNA of our credit business is based on operating a loan portfolio which is highly collateralized. From our total portfolio of R$19.5 billion, 73% was either collateralized by assets, invoices or payroll flows. Though we remain committed to gaining share across products, we strategically decided to decelerate credit underwriting in the quarter, monitoring the performance of the portfolio in an environment of increasing NPLs. 11 NPL > 90 days In % In addition to having a highly collaterlized loan portfolio and a strong capital base, our coverage ratio reached 129% in the quarter. It is worth noting that our provisionings are done under IFRS based on the expected credit losses (ECL) model.

In our innovative marketplace business, we reached a record of 113 million gross revenues this quarter, 101% higher than in 2Q21. This growth is explained primarily by expanding take rates, followed by larger Gross Merchandise Volume (GMV). We achieved a record of 7.5 million transactions in the quarter, growing 44% relative to 2Q21. 12 Inter Shop revenues and Gross merchandise volume (GMV) In R$ Million Gross take-rate Net take-rate (%) Other Highlights: 73% of Inter Shop customers are recurrent 555,000 new customers More than 800,000 available SKUs and 900 sellers in Super App including new partnerships with Brastemp, Consul, ABC da Construção, Acer and Positivo/Vaio Launched an integrated end to end experience to book hotels Net take-rate also showed strong growth, reaching 4.4% in 2Q22, which supports our continued focus on margin expansion and cashback optimization.

The Company manages the market risk of positions classified in the banking book as well as in the trading book. The risk management team monitors mismatches between indexes and terms of active and passive positions, checking the strategies (and risks) assumed on a daily basis. The Bank currently has an adequate market risk considering the strategy and complexity of the business, as well as in line with the Institution’s Risk Appetite Statement. Additionally, it is noteworthy that Inter currently uses tools such as Value-At- Risk (VaR), delta EVE and delta NII in the periodic management of market risk. The management of liquidity risk independently promotes the daily control and monitoring of Banco Inter’s liquidity in accordance with Resolution 4557 of the Central Bank of Brazil, as well as in line with the best market practices.

Additionally, the Institution has a fragmented client base with demand deposits (and term deposits), as well as a robust (available) stock of collateral for the issuance of real estate credit notes (LCI) that potentially generate stability in liquidity management. 17 MANAGERIAL REPORT | 2Q22 Market risk management Liquidity management Appendix Activity ratio Activity ratio per quarterly cohort In %
