June 6, 2023​

To Brokers, Dealers, Commercial Banks, Trust Companies and Other Securities Intermediaries:

We have been engaged by ITB Holding Brasil Participações Ltda., a limited liability company organized under the laws of the Federative Republic of Brazil (“Purchaser”) and an indirect wholly owned subsidiary of Itaú Unibanco Holding S.A., a company organized under the laws of the Federative Republic of Brazil (“IUH”), to act as Information Agent (the “Information Agent”) in connection with the offer to purchase: (1) any and all outstanding common shares, no par value per share (the “Common Shares”) of Banco Itaú Chile (formerly known as Itaú Corpbanca), a publicly-traded special banking corporation (sociedad anónima especial bancaria) organized under the laws of the Republic of Chile (the “Company”), held by U.S. holders (within the meaning of Rule 14d-1(d) under the U.S. Securities Exchange Act of 1934, as amended (the “Exchange Act”), which defines a U.S. holder as “any security holder resident in the United States”); and (2) any and all outstanding American Depositary Shares (each of which represents one-third of one Common Share) (the “ADSs,” and together with the Common Shares, the “Shares”), held by holders, wherever located, in each case other than any Shares owned directly or indirectly by IUH and/or its affiliates, for 8,500.00 Chilean pesos in cash per Common Share and 2,833.3333 Chilean pesos in cash per ADS (together, the “U.S. Offer Price”), without interest and less (i) any applicable brokerage fees and commissions and (ii) applicable withholding taxes, upon the terms and subject to the conditions set forth in the U.S. Offer to Purchase and other related materials, including the form of acceptance for the Common Shares (the “Common Share Acceptance Form”), the letter of transmittal for ADSs (the “ADS Letter of Transmittal”) and the notice of “guaranteed delivery” for the ADSs (the “ADS Notice of Guaranteed Delivery”) which, together with any amendments or supplements thereto, collectively constitute the “U.S. Offer.” Purchaser is making a concurrent all cash tender offer directed to holders of Common Shares, but not holders of ADSs (the “Chilean Offer,” and together with the U.S. Offer, the “Offers”).

The U.S. Offer Price for Shares accepted for payment pursuant to the U.S. Offer will be paid to holders of Shares in U.S. dollars, less the amount of any fees or commissions, expenses and withholding taxes that may be applicable, to such holders. All payments for Shares accepted for purchase pursuant to the Offers will be made within four Chilean business days following the announcement of the results of the Offers (the

date of such payment, the “Settlement Date”). The U.S. Offer Price paid to holders of Shares will be converted into U.S. dollars based on the Observed Exchange Rate, published by the Central Bank of Chile (Banco Central de Chile) in the Official Gazette of Chile two Chilean business days immediately prior to the Settlement Date. All payments to holders of Shares tendered pursuant to the U.S. Offer will be rounded to the nearest whole U.S. cent. The U.S.$/Ch$ exchange rate as published by the Central Bank of Chile in the Official Gazette of Chile on June 2, 2023, was U.S.$1.00 = Ch$804.60.
