YoY) . Prepaid revenue declined -3.9% YoY, due to the continued migration of customers to hybrid plans . Even so, this represents a slowdown in losses compared to previous quarters, driven by a sequential increase in recharge frequency . On a quarterly comparison, revenue registered an increase of +2.2%, the best sequential performance since 1Q25. Despite this recovery, prepaid accounts for 14.2% of MSR and 8.9% of Net Operating Revenue .

Our B2B segment continues to gain share within Vivo’s revenue, accounting for 22.6% of the total, an increase of +1.4 p.p. YoY, with 2025 marking its strongest annual growth in recent years .

B2C Products & Services Considering all B2C products and services — both connectivity and new business — the average monthly revenue per RGU¹ reached R$65.8 in 2025, reinforcing Vivo’s services ecosystem as a value proposition that goes beyond connectivity . 4Q25 Results | Costs Costs of Services and Products Sold increased by +9.7% YoY, boosted by the growth in revenues from digital services and electronics. Costs of Services and Products Sold Services +8.2% YoY | 11.3% of Revs (+0.1 p.p. YoY) The growth reflects the strong acceleration of digital solutions revenues, mainly in the B2B and music and video OTT services. Products Sold +11.6% YoY | 9.7% of Revs (+0.4 p.p. YoY) Expansion is driven by the strong sales performance of Handsets & Electronics. 7 4Q25 Results | Personnel: +6.4% YoY | 10.3% of Revs ( -0.1 p.p. YoY) The evolution reflects annual salary adjustments as well as headcount growth in areas such as Digital Services, IT and New Businesses . Commercial & Infrastructure: -2.6% YoY | 22.8% of Revs ( -2.3 p.p. YoY) The annual drop is mainly related to the one -time increase in infrastructure costs registered in 4Q24, as well as the reduction of network rental expenses . Provision for Bad Debt: +4.2% YoY | 2.5% of Revs ( -0.1 p.p. YoY) Annual increase aligned with the growth in postpaid and recurring revenue -generating customers . PBD decreased -0 .2% on a QoQ basis . PBD's control demonstrates the prioritization of customers in the payment of connectivity bills, in addition to the execution of credit and collection actions by the Company . General & Administrative: +8.2% YoY | 2.6% of Revs (+0.0 p.p. YoY) The growth was driven by higher expenses with external services, development and systems maintenance and other administrative services . Other Operating Income (Expenses): -35.2% YoY | 2.2% of Revs ( -1.4 p.p. YoY) In 4Q25, we had R$102.1 million¹ in benefits from the sale of concession related assets (R$96 million in copper and R$6 million in real estate), compared to R$206 million of asset sales and R$386 million from reversal of contingencies in 4Q24. We are committed to delivering on the R$4.5 billion of asset sales related to the migration from concession to authorization (R$3 billion in copper and R$1.5 billion in real estate), with the value capture mainly concentrated in 2026 and 2027. 8 Costs from Operations rose +4.4% YoY, driven by higher expenses related to commercial activity and partially offset by asset sales linked to the former fixed voice concession.

R$ million EBITDA We ended 4Q25 with an EBITDA (Earnings Before Interest, Taxes, Depreciation and Amortization) of R$6,699.0 million, +8.1% YoY, with an EBITDA margin of 42.9%, +0 .4 p.p. YoY . While EBITDA ex-Concession Migration Effects² reached R$6,596 .9, up +17.7% YoY, with a margin of 42.3%. EBITDA AL³ also expanded, +9.2% YoY, with a margin of 33.8%, up +0 .7 p.p. YoY . Depreciation and Amortization Depreciation and Amortization expenses increased +1.6% YoY, with a deceleration in the annual growth rate as results entered a more comparable basis . Since 2Q25, PPA depreciation and amortization have declined due to the conclusion of amortization related to part of the intangible assets recognized in the GVT acquisition, which previously amounted to approximately R$24 million per quarter . This effect was partially offset by higher leasing depreciation under IFRS 16, reflecting the incorporation of assets from the FiBrasil and CyberCo acquisitions . Financial Results Financial Results for 4Q25 amounted to an expense of R$663 .7 million, representing an increase of +93.8% YoY . This growth reflects an atypical comparison base in 4Q24, which recorded a positive effect of R$406 million, resulting from the reversal of monetary updates of provisions related to the migration from the fixed voice concession regime to authorization . Despite the increase in expenses, the impact was partially mitigated by the expansion of financial revenue, driven by the increase in the interest rate and improved liquidity throughout the period . Net Income In 4Q25, Net Income¹ reached R$1,876 .9 million, an increase of +6.5% YoY, driven by business growth which supported an EBIT evolution of +18.0% YoY . 9 4Q25 Results | Capex 1. Does not include amounts related to IFRS 16 effects, licenses and CyberCo Brasil acquisition. Capex¹ totaled R$2,359 million in 4Q25, a decline of -4.0% YoY, representing 15.1% of Net Operating Revenue, -1.7 p.p. versus the same period last year, following the trend of lower investment intensity . Free Cash Flow Free Cash Flow totaled R$2,287 million in 4Q25, growing +111.9% YoY, due to positive EBITDA growth, reduced disbursements from leasing contracts (which have varied little over the last six quarters), lower Capex execution, and reduced tax payments and financial expenses . In addition to these effects, we had a reduction in working capital consumption year-over-year, due to one -off events that increased consumption in 2024 . We continue to expand our 5G network, covering 716 municipalities (+1.4x YoY) and 67.7% of the Brazilian population . Fiber is also an important driver of the Company's growth, which translates into investments dedicated to expanding homes passed (+6.4% YoY) and homes connected (+12.0% YoY) . 10 For the year, Free Cash Flow after leasing payments reached R$9,153 million (+11.4% YoY), as a result of EBITDA growth, partially offset by higher lease payments, investments, financial payments and lower working capital generation . 4Q25 Results | Indebtedness Loans, Financing and Debentures Net Debt L.T. Debt Profile The Company's gross debt (ex-IFRS 16 leases) totaled R$4,914 million at the end of 4Q25, a decrease of -10.7% YoY, reflecting the settlement in July 2025 of the debenture related to the 7th Issuance, 1st Series , in the amount of R$1,500 million .
