These obligations arise from the enactment of the Holding Foreign Insiders Accountable Act (HFIAA), which is part of the U.S. National Defense Authorization Act for Fiscal Year 2026, as detailed in the material presented at the meeting.

**(ii)** In the second off-agenda item, the Board members, in compliance with Article 22, item vii, of the Bylaws, **<u>approved</u>** the Management's proposal to enter into a Share Purchase Agreement ("SPA") between the Company and **IHS Fiber Brasil – Cessão de Infraestruturas Ltda.**, with the objective of the Company acquiring 51% (fifty-one percent) of the share capital of **I-Systems Soluções de Infraestrutura S.A.

The Transaction hereby approved is subject to verification and fulfillment of certain conditions precedent, customary for this type of transaction, including, among others, the obtaining of the necessary authorizations from the competent authorities, such as the National Telecommunications Agency (ANATEL) and the Administrative Council for Economic Defense (CADE), as well as the applicable corporate approvals, as the case may be.

Upon consummation of the Transaction, the Company, which already held 49% (forty-nine percent) of I-Systems' share capital, will come to hold 100% (one hundred percent) of its shares, thereby rendering I-Systems a wholly owned subsidiary of the Company.

Finally, the Board Members **<u>authorized</u>** the Company's Officers to negotiate, enter into and sign any and all the terms, agreements, contracts, and other documents, as well as to perform all acts relevant and necessary for the implementation and closing of the Transaction, strictly in accordance with the terms and conditions set forth in the supporting materials presented at the meeting, which shall remain filed at the Company's headquarters.
