The average monthly revenue per RGU² continues to grow. In the last 12 months, we achieved R$67.2 (+6.9% YoY), boosted by revenues from B2C connectivity (+5.0% YoY) and B2C new businesses (+31.5% YoY), reinforcing the appeal of our ecosystem of services that go beyond connectivity.

Mobile Business Mobile Service Revenue (MSR) increased by +6.6% YoY, supported by Postpaid Revenue1 (+7.8% YoY), that represents 86.6% (+1.0 p.p. YoY) of MSR. Our strategy remains successful as we continue to grow our postpaid customer base (+6.9% YoY), ending the quarter with 72.1 million accesses. This was fueled by significant migrations from prepaid to control, and from control to pure postpaid, as well as new customer acquisitions. Additionally, postpaid ARPU (excluding M2M and dongles) increased +0.8% YoY to R$52.6, reflecting an improved customer mix and service revenue dynamics. The Company achieved its highest annual growth in Handsets and Electronics Revenue (+26.6% YoY) since 2Q21. This increase was fueled by a more competitive portfolio, and a new go-to-market strategy that enhanced the availability of in-store devices, accessories, and electronics in general. In 1Q26, sales of 5G-compatible smartphones accounted for 97.2% of total units sold (+7.8 p.p. YoY). Prepaid Revenue continues to show sequential improvements in its YoY performance; in 1Q26, it posted a slight decrease of -1.0% YoY, reflecting the continued migration of customers to hybrid plans. This is the fourth consecutive improvement in YoY variation since 1Q25, when the business declined -11.4% YoY. This was driven by monetization initiatives, such as higher top-up frequency, leading to a +10.0% YoY ARPU increase.

In 1Q26, homes connected reached 8.0 million accesses (+11.5% YoY), driving a +1.2 p.p. YoY increase in the take-up rate, that ended the quarter at 25.4%. Despite strong commercial activity, FTTH ARPU rose +0.8% QoQ to R$87.7 and FTTH churn remained flat YoY at 1.5%. Our convergent FTTH customer base comprises 5.1 million accesses, of which 3.6 million are via Vivo Total² (+32.6% YoY). This offer accounted for 83.2% of FTTH additions in our own physical stores in 1Q26, reinforcing the importance of convergence as a key growth lever. Vivo Total now represents 44.7% of all FTTH accesses (+7.1 p.p. YoY), clearly indicating significant potential for further expansion within the Company's existing customer base. Corporate Data, ICT and Digital Services revenue grew by +8.5% YoY, totaling R$1,423 million in 1Q26, of which R$1,013 million from Fixed Digital B2B revenues (+14.8% YoY). 1Q26 Results 5 1.

In 1Q26 LTM, digital services revenues reached R$5,401 million, up +23.8% YoY, accounting for 8.9% of total revenues (+1.2 p.p. YoY). Reflecting this momentum, the B2B increased its share to 22.6% of the Company's total revenues (+1.0 p.p. YoY).

We remain committed to our R$4.5 billion of asset sales from the concession to authorization migration (R$3.0 billion in copper and R$1.5 billion in real estate), expected to accelerate in 2026–2027 and be completed in 2028. From EBITDA to Net Income 1Q26 Results 9 1. Considers the net income attributed to Telefônica Brasil. EBITDA to Net Income – 1Q26 R$ million Financial Results The financial result in 1Q26 totaled a net expense of R$720 million, representing a +26.6% YoY increase. This performance was primarily driven by: • Higher debt levels following the FiBrasil acquisition, reflecting both the cash disbursement related to the transaction and the consolidation of its 3rd debenture issuance; • An increase in lease liabilities, as the Company continues to invest in network quality and expansion. Net Income In 1Q26, Net Income¹ reached R$1,261.1 million, up +19.2% YoY, the highest increase since 1Q24, driven by business growth, which underpinned EBIT growth of +16.9% YoY. Depreciation and Amortization Depreciation and amortization increased by +4.5% versus the same period last year. Since 2Q25, PPA-related depreciation and amortization have declined due to the conclusion of the amortization of part of the intangible assets recognized in the GVT acquisition (approximately R$24 million per quarter). This reduction was partially offset by higher IFRS 16 depreciation, mainly reflecting the consolidation of FiBrasil's assets and 5G-related investments. EBITDA EBITDA (Earnings Before Interest, Taxes, Depreciation and Amortization) for 1Q26 was R$6,209.3 million, an increase of +8.9% compared to 1Q25, with an EBITDA margin of 40.2%, +0.5 p.p. YoY. Capex 1Q26 Results 10 Free Cash Flow totaled R$2,199.9 million in 1Q26, increasing +3.6% YoY (+R$75.7 million), mainly driven by EBITDA growth, partially offset by higher tax payments and greater working capital consumption compared with 1Q25, which was impacted by nonrecurring events, such as the anticipation of payments in the prior year that resulted in a lower comparison base. 1. Does not include amounts related to IFRS 16 effects and licenses. Free Cash Flow Capex¹ totaled R$2,047.5 million in 1Q26, an increase of +9.6% YoY, accounting for 13.2% of Net Operating Revenue, +0.3 p.p. YoY, in line with 1Q25 and below our 2025 average, as we continue to pursue optimal Capex allocation. We continued to expand our 5G network, now live in 905 municipalities and covering 71% of the Brazilian population. Fiber remains a relevant growth driver, supported by investments in network expansion and customer connections, with homes passed and homes connected growing +6.2% YoY and +11.5% YoY, respectively. More than 75% of Capex is dedicated to strengthening both the mobile network and ongoing fiber expansion across 453 cities. Indebtedness 1Q26 Results 11 Loans, Financing and Debentures Net Debt \| ex-IFRS 16 L.T. Debt Profile Considering Cash, Investments and Derivatives, the Company reported a net cash position of R$4,490.6 million as of March 31, 2026. Including the effects of IFRS 16 leases, net debt totaled R$10,541.6 million at the end of 1Q26. Gross debt (excluding IFRS 16 leases) totaled R$4,838.1 million at the end of 1Q26, representing a -1.5% QoQ reduction, mainly driven by regular amortizations across loans, financings and other liabilities, which more than offset the consolidation of FiBrasil's debt during the period. As a result, net debt to EBITDA decreased from 0.5x in 1Q25 to 0.4x in 1Q26, underlining the ongoing strengthening of our balance sheet. Of the total gross debt, 99% is denominated in local currency and 1% in foreign currency. The Company's foreign exchange exposure is fully hedged through derivative instruments. 1.
