After over 22 years leading the organization, Mr. Roberto Setubal has reached the age limit for acting as our CEO. As of the Annual General Stockholders’ Meeting of 2017, Roberto leaves the Executive Presidency of Itaú Unibanco and, together with Pedro Moreira Salles, will act as co-chairman of the Company’s Board of Directors.

2017

Credit Intelligence Bureau

In January 2016, we announced that our subsidiary Itaú Unibanco S.A. entered into a non-binding memorandum of understanding (MoU) with Banco Bradesco S.A., Banco do Brasil S.A., Banco Santander (Brasil) S.A. and Caixa Econômica Federal in order to create a credit intelligence bureau, or Gestora de Inteligência de Crédito S.A. (“GIC”).

In November 2016, CADE (the Brazilian antitrust agency) approved the transaction with certain restrictions and, on June 14, 2017, GIC was incorporated by Itaú Unibanco S.A., Banco Bradesco S.A., Banco do Brasil S.A., Banco Santander (Brasil) S.A., and Caixa Econômica Federal (through its subsidiary Caixa Participações S.A. ).

GIC is structured as a Brazilian corporation and shareholders share its control, with each of them holding a 20% equity ownership. Its board of directors is composed of members appointed by the shareholders and its executives will be exclusively dedicated to GIC’s businesses, preserving the independent nature of GIC’s management. GIC’s technical and analytical platform will be developed and implemented through a services agreement with LexisNexis® Risk Solutions FL Inc.

Itaú CorpBanca

In April 2016, we closed the merger of Banco Itaú Chile with and into CorpBanca and, as a result, acquired the control of the resulting entity – Itaú CorpBanca. On that same date, we entered into the Shareholders’ Agreement of Itaú CorpBanca (“Itaú CorpBanca’s Shareholders’ Agreement”), which entitles us to appoint, together with the Corp Group, former controlling shareholder of CorpBanca, the majority of members of Itaú CorpBanca’s Board of Directors. These members are appointed according to the ownership interest of each party, and we have the right to elect the majority of members elected by this block. Also on that same date, Itaú Unibanco consolidated Itaú CorpBanca in its financial statements, adding approximately R$114 billion of assets to its balance sheet.

These operations were implemented as a result of the commitments we assumed in the Transaction Agreement, entered into with CorpBanca and its controlling shareholders in January 2014 and amended in June 2015.

In January 2017, we executed an amendment to the Transaction Agreement, which provided for (i) the postponement of the acquisition date of the shares held by Corp Group in Banco CorpBanca Colombia S.A. (“CorpBanca Colombia”) from January 29, 2017 to January 28, 2022, subject to receipt of the applicable regulatory approvals; (ii) the modification of the previously defined structure for the combination of operations of Itaú Unibanco and Itaú CorpBanca in Colombia to a sale and purchase of assets and liabilities, concluded in April 2017; and (iii) the replacement of the obligation to consummate an initial public offering (IPO) of CorpBanca Colombia for the obligation to register CorpBanca Colombia as a public company and list its shares on the Colombian stock exchange.

In accordance with the put option set forth in Itaú CorpBanca’s Shareholders’ Agreement, we increased our ownership interest on three occasions:(i) in October 2016, 10.9 billion shares of Itaú CorpBanca for approximately R$288.1 million, increasing our equity stake to 35.71% from 33.58%, and (ii) in September 2017, 1.8 billion shares of Itaú CorpBanca for approximately R$55.6 million increasing our equity stake to 36.06% from 35.71%; and (iii) in October 2018, we acquired 10.6 billion shares of Itaú CorpBanca for approximately R$365 million, increasing our equity stake to 38.14% from 36.06%. In all cases, there were no changes in the governance of Itaú CorpBanca.

Sale of Group Life Insurance Business

In September 2016, we entered into an agreement for the sale of our group life insurance operations to Prudential do Brasil Seguros de Vida S.A. The transfer of shares and the financial settlement of this transaction took place after compliance with certain conditions provided for in the agreement on April 1, 2017. This transaction reinforces our strategy, which has already been disclosed, to focus on mass-market insurance products that are typically related to retail banking.

Acquisition of Citibank Retail Business in Brazil

In October 2016, we entered into an Equity Interest Purchase Agreement for the acquisition of the retail business conducted by Banco Citibank S.A. and other companies of its conglomerate (“Citibank”) in Brazil, including loans, deposits, credit cards, branches, on-shore wealth management and insurance brokerage, as well as of the equity investments held by Citibank in TECBAN – Tecnologia Bancária S.A. and in CIBRASEC – Companhia Brasileira de Securitização.

Citibank’s retail business in Brazil (which includes 71 branches) had, as of the date of execution of the Equity Interest Purchase Agreement, approximately 315,000 retail bank clients, approximately 1. 1 million credit cards and a credit portfolio of approximately R$6 billion and, as of December 31, 2015, approximately R$35 billion in deposits and assets under management. We estimate that the impact on our principal capital (Tier I) resulting from this transaction would be approximately 40 basis points (utilizing the Basel III methodologies).

In August 2017, CADE approved Itaú Unibanco’s acquisition of Citibank’s retail business in Brazil by means of Itaú Unibanco executing an agreement with CADE that includes measures to improve competition in the banking sector. In October 2017, we obtained the last required authorization with the Central Bank of Brazil in connection with such transaction.

With these regulatory approvals obtained, the financial settlement of the acquisition of Citibank retail business was carried out on October 31, 2017, the date when Itaú Unibanco became responsible for these operations. The financial settlement of the acquisition of the operations related to the individuals segment of Citibank Corretora and the corresponding transfer of these operations was carried out on December 1, 2017. The acquisitions of the equity investments held by Citibank in TECBAN and Cibrasec and the respective financial settlements were completed on December 26, 2017 after the compliance with the provisions in the respective stockholders’ agreements of these companies.

XP Investimentos

On May 11, 2017, Itaú Unibanco S.A. entered into a Share Purchase Agreement with XP Controle Participações S.A. (“XP Controle”), G. A. Brasil IV Fundo de Investimento em Participações and Dyna III Fundo de Investimento em Participações, among others (“Sellers”), for purchasing, at a first acquisition, 49.9% of the capital stock (representing 30.1% of common shares) of XP Investimentos S.A. (“XP Holding”), the holding company that consolidates all investments of the XP group (“XP Group”), including XP Investimentos Corretora de Câmbio, Títulos e Valore Mobiliários S. A(“XP Investimentos”), by means of a capital increase of R$600 million and the acquisition of XP Holding’s shares from the Sellers for R$5.7 billion, and these amounts are subject to contractual adjustments provided for since the execution date the agreement (“First Acquisition”). XP Holding´s total capital stock (before the First Acquisition) was valued at approximately R$12 billion.

Itaú Unibanco S.A. obtained authorizations from CADE, the Brazilian antitrust agency in March 2018, and from the Central Bank of Brazil (BACEN) in August 2018to consummate the First Acquisition. Accordingly, Itaú Unibanco S.A. signed (i) a Concentration Control Agreement (“CCA”) with BACEN and undertook the commitment to:(a) not to acquire the ownership control of XP Holding for eight years as from the execution of the CCA; and (b) cancel Itaú Unibanco’s call option and XP Controle’s put option; and (ii) a CCA with CADE and undertook the commitment to:(a) if requested, distribute its own investment products through open platforms from competitors of XP Holding’s platforms at an arm’s-length basis; and (b) not direct its customers to XP Holding’s platforms.

On the closing date of the First Acquisition, which will take place on August 31, 2018, Itaú Unibanco S.A. and certain of the Sellers will execute a Shareholders’ Agreement that will reflect, among others, provisions regarding the rights of Itaú Unibanco as a minority shareholder of XP Holding, as well as Itaú Unibanco’s right to appoint two out of seven members of the XP Holding’s Board of Directors.

Subject to the future approval from proper government authorities, in addition to the First Acquisition, Itaú Unibanco has agreed to acquire in 2022 an additional 12.5% stake of XP Holding’s capital stock, which will lead Itaú Unibanco S.A. to hold 62.4% of the total capital stock of XP Holding (equivalent to 40.0% of common shares) based on a multiple (19 times) of XP Holdings earnings.

In view of this scenario, it is worth mentioning that the operation and management of the business of all XP Group’s companies, including XP Investimentos, will continue to be independent, segregated and autonomous, preserving its current principles and values. The control of the XP Group will continue to be held by XP Controle’s shareholders and the current officers and executives of XP Holding, XP Investimentos and other subsidiaries will remain in charge of their respective business, so as to ensure that XP Investimentos continues to operate as an open and independent platform, offering a diverse range of its own and third party products to its customers, competing freely with other brokers and capital market distributors, including those controlled by Itaú Unibanco’s conglomerate, without any restrictions or barriers. Itaú Unibanco will act as a minority shareholder and will have no influence on the commercial and operational policies of XP Investimentos or any other company in the XP Group, neither will have any preference or exclusivity rights regarding the sale of such products.

We estimate that the First Acquisition will impact Itaú Unibanco’s Basel index by 0.80%.

Initial Public Offering of IRB

In July 2017, IRB-Brasil Resseguros S.A. (“IRB”) carried out an initial public offering of its common shares, which consisted of a public offering for R$27.24 per share, and a secondary offering by its controlling shareholders of 63,960,000 registered book-entry common shares with no par value to (i) the public in Brazil, (ii) certain qualified institutional buyers in the United States (as defined in Rule 144A under the U. S. Securities Act of 1933, as amended, or the Securities Act), and (iii) institutional and other investors elsewhere outside the United States and Brazil that are not U. S. persons (as defined in Regulation S under the Securities Act, or Regulation S). As a result of this initial public offering, Itaú Vida e Previdência S.A. sold 677,400 common shares, representing the total interest held by Itaú Vida e Previdência S.A. in IRB’s capital stock, and Itaú Seguros S.A. sold 9,618,600 common shares, representing 3.1% of IRB’s capital stock, reducing its interest in IRB to 11.64% of IRB’s capital stock, remaining among the controlling block shareholders pursuant to the company’s shareholders agreement. The proceeds received by Itaú Seguros S.A. and Itaú Vida e Previdência S.A. in the initial public offering totaled R$280,463,040.00.

In accordance with Article 24 of CVM Instruction No. 400, the number of common shares initially offered could be increased by up to 9,594,000 common shares, representing up to 15% of the common shares initially offered, if the stabilizing agent (or any person acting on behalf of the stabilizing agent) exercises the over-allotment option. As a result of the full exercise of the over-allotment option by the stabilizing agent on August 28, 2017, Itaú Seguros S.A. became the owner of 11.14% of IRB’s capital stock.

2016

Acquisition of Recovery do Brasil Consultoria S.A.

In March 2016, after obtaining regulatory authorizations, we consummated the acquisition of (i) 89.08% interest in the capital stock of Recovery do Brasil Consultoria S.A. (“Recovery”), of which we purchased 81.94% from Banco BTG Pactual S.A. (BTG) and 7.14% from other shareholders, as well as (ii) approximately 70% of a portfolio of, at that time, R$38 billion in credit rights held by BTG.

Alliance with MasterCard in the payment solutions market in Brazil

In May 2016, the Court of CADE approved, with certain restrictions, a 7-year term agreement between our subsidiary Itaú Unibanco S.A. and MasterCard Brasil Soluções de Pagamento Ltda. (MasterCard), to create an alliance in the payment solutions market in Brazil (the Strategic Alliance), to operate, through a company controlled by MasterCard, a new electronic payment network under a brand with domestic and international acceptance.

Sale of Group Life Insurance Business

In April 2017, after obtaining the required regulatory authorizations and fulfilling conditions, we completed the sale of our group life insurance operations to Prudential do Brasil Seguros de Vida S.A. This transaction reinforces our strategy, which has already been disclosed, to focus on mass-market insurance products that are typically related to retail banking.

Acquisition of Itaú BMG Consignado shares

In December 2016, after obtaining the required regulatory authorizations and fulfilling conditions, we completed the acquisition of the total equity interest held by Banco BMG in Itaú BMG Consignado S.A., corresponding to 40% of Itaú BMG Consignado’s total share capital. We paid R$1.46 billion and are now the holders of 100% of the total capital.

Acquisition of ConectCar

On January 29, 2016, after obtaining the necessary regulatory authorizations and the fulfillment of conditions, we concluded, through our subsidiary Rede, the acquisition of 50% of the share capital of ConectCar Soluções de Mobilidade Eletrônica S.A. ("ConectCar") from Odebrecht Transport S.A., for the amount of R$170 million. The remaining 50% of ConectCar's capital stock is owned by Ipiranga Produtos de Petróleo S.A., a company controlled by Ultrapar Participações S.A. and the shareholders share control of ConectCar.
