Major Capital Increase through Bonus Shares at Itaú Unibanco

Itaú Unibanco Holding S.A. has announced an important development for its stockholders and the broader market—an increase in its subscribed and paid-in capital by over 12 billion Brazilian reais. The decision was made by the Company's Board of Directors during a meeting held on December 18, 2025. This strategic move is anticipated to strengthen the bank's financial position and enhance shareholder value without impacting the existing equity of shareholders.

Key Highlights of the Proposal

The proposal contains several critical components:
1. Capital Increase: The company's capital will rise from BRL 124,063,060,190 to BRL 136,909,898,070, reflecting a total increase of BRL 12,846,837,880, as recorded through capitalization of amounts set aside in the revenue reserves.
2. Bonus Shares Allocation: Under the new proposal, 321,170,947 bonus shares will be distributed free of charge to stockholders. This includes 163,623,582 common shares and 157,547,365 preferred shares. Stockholders will receive three new shares for every 100 shares they currently hold, thereby enhancing their investment in the bank.
3. Record Dates: Shareholders as of December 23, 2025, in Brazil, and December 29, 2025, in the U.S., will be entitled to the bonus shares. This dual market approach highlights Itaú Unibanco's commitment to providing value to all of its investors.
4. Post-Distribution Rights: The newly issued shares will enjoy the same entitlement to earnings as the common and preferred shares already held by stockholders starting December 30, 2025.

Important Dates and Trading Information

• - Trading Release for New Shares: The newly issued shares will start trading without bonus rights on December 26, 2025.
• - Share Accounting: The bonus shares will be accounted for on December 30, 2025, confirming the new holdings of shareholders.
• - Interest on Capital (IoC): Payments for IoC will remain at BRL 0.01765 per share (net amount of BRL 0.015). This ensures that total monthly payments to stockholders will rise by 3% once the bonus shares are included.

Fractional Shares and Auction Process

Shareholders will also be able to transfer any fractional shares that arise from the allocation of bonus shares from January 2 to February 2, 2026. Any untransferred fractions will be sold at auction, with net proceeds being distributed to shareholders on a date yet to be announced.

Cost and Tax Considerations

The attributed cost of the bonus shares is set at BRL 40.00 per share in accordance with relevant regulatory instructions. This valuation is essential for shareholders who utilize equity methods to assess their interests in the company.

Implications for International Investors

For those trading on international markets, such as ADR holders in the U.S., they will also be eligible for a 3% bonus share allocation. This means 3 new ADRs will be granted for every 100 ADRs held as of December 29, 2025. This aligns with Itaú's strategy to maintain parity across its markets while providing attractive opportunities for both domestic and international investors.

Itaú Unibanco's recent announcement serves as a significant milestone in its ongoing growth strategy, reinforcing the bank's commitment to delivering value to its stockholders while ensuring strong capitalization and financial health moving forward.
