🧾 What This Document Is

This is a 6-K form, which foreign companies listed on U.S. exchanges use to make important announcements to the market. This specific filing is a mandatory disclosure of a transaction with a "related party"—a company it's already connected to. The purpose is transparency, showing investors that dealings between these affiliated companies are fair and follow the rules.

👉 Why it matters: It ensures that the bank isn't making secret deals with its friends that could hurt regular shareholders. Think of it as a required public receipt for business done within the family.

🏢 What The Company Does

In simple terms, Itaú Unibanco is Brazil's largest private bank. It's a massive financial conglomerate that offers everything from basic checking accounts and loans to investment banking and insurance. This filing involves two parts of its extended corporate family:

• Itaú Unibanco S.A.: The main, controlled bank.
• Porto Seguro: A separate insurance company that is considered an "affiliate" of the bank (meaning there's a significant ownership or relationship link).

👉 The relationship: They are not strangers; they are business partners under a shared corporate umbrella. This transaction is about the bank's branches selling Porto Seguro's insurance products.

💰 The Financial Details

The core of the filing is an operating agreement. Here’s what you need to know:

• What it is: A formal agreement where Itaú's bank branches promote and sell insurance policies made by Porto Seguro.
• The Payday: For doing this, the bank gets paid. The monthly payment crossed a key threshold—over BRL 50 million—which is what triggers this public announcement.
• The Big Number: The bank estimates it will receive a total of approximately BRL 441 million from this agreement during the full fiscal year 2026.

⚖️ Is It a Fair Deal?

The company's management had to justify that this deal is fair. They state it:

• Meets "commutative conditions" – This is legalese for "a fair exchange of value." Both sides get something worthwhile.
• Follows their official policy on related-party transactions.
• Was not influenced by anyone from Porto Seguro within Itaú's decision-making process.

👉 In plain English: They're saying the deal is done at market rates, follows internal rules, and no one from the insurance company had a say in approving it from the bank's side.

🔄 Recurrence & Future Reporting

This is a recurring, ongoing business relationship—not a one-time event. Because it's part of the normal course of business, the company won't file a new announcement for every single payment this year. They have regulatory permission to be silent on further transactions under this same agreement for the rest of 2026.

📅 Key Dates & Context

• Announcement Date: April 1, 2026.
• Regulatory Backing: This disclosure follows specific rules set by Brazil's securities regulator, CVM Resolution No. 80/22.

👉 What this signals: Itaú is proactively following Brazilian corporate governance rules to assure the market that this related-party revenue stream is正规化 (regularized) and transparent.

🧠 The Analogy

Think of a popular airline that has an exclusive credit card. The airline (Itaú's bank) advertises and pushes the credit card (Porto Seguro's insurance) to all its passengers at the gate. In return, the credit card company (Porto Seguro) pays the airline a fee for every customer signed up. This filing is the airline telling its own shareholders, "Hey, we're making good money from this partnership, and here's the general amount."

🧩 Final Takeaway

Itaú Unibanco is publicly disclosing a lucrative, ongoing insurance-selling partnership with an affiliated company, Porto Seguro, that will bring in an estimated BRL 441 million in revenue in 2026. The move is a standard but important transparency exercise to assure investors the deal is fair and properly managed.
